[wanton orchid]

I know

for you to know if you wonder
that result is for 5C

[twin dew]

Ok, so no problem for almost any Li-Ion battery.

Just a thing that would be easy to not know about.

[wanton orchid]

I consider 3C maximum achievable for more than few minutes without killing battery array
and it's not recommended

Anyway the led will burn like hell otherwise

I planned for led temperature power throttling

[twin dew]

Some cells meant for RC etc. use are specced to be good up to 25C IIRC.

[wanton orchid]

but it's practical long life pocket light
so it's not li-on cheating

So no over 5C

and it's already a LOT

focus is only compactness

so nimh/alkaline planning

btw what I calculated is maximum spec nimh 5C
if you have cheaper battery you will not achieve that unless you go 7C
but I would tell to only do that for like 30s maximum

planning for battery temperature and tension drop protection too

I want the best of the best of pocket light

it's not simple

but it's exciting

Anyway more than that and it's the led that is throttling

the idea is to have an equilibrium
where you are permitted to use the best out of every part
on-demand

permanent power settings does not allow to go that high

only flash button allow that

[twin dew]

Much better idea IMHO to use Li-Ion at this time, even if just one of the standard cylindrical cells with all the protections both physical and electrical already included.

[wanton orchid]

why ?

[twin dew]

Much higher power delivery for same size, both in current and over time.

[wanton orchid]

lion have more throughput but less capacity
and the led will only rarely be used at its maximum power

remember light sensitivity is logarithmic
2 step back of flashing max and you are already down to 1C

[twin dew]

No... Li-Ion has higher power density and lighter weight than NiMH.
Alkaline primary cells can be better, not sure.

[wanton orchid]

wrong

li-on is lighter for power

but have less volume density

[twin dew]

Ah, yeah, ok.

[wanton orchid]

especially for small batteries which still must get the protection layers

[twin dew]

Was already checking...

[wanton orchid]

Also nimh is more stable when not used quickly

li-on definetely is better for blast

but led you are only ever blasting with at this point

it will stay at 0.2-1C range most of the time

and for night small use it will even drop much lower

and it will stay in pocket for so long until you use it

[twin dew]

The Wh rating between similar size NiMH and Li-Ion seems to be somewhat conflicted, because of the way different discharge voltage curves and the higher losses to internal resistance in NiMH.

[wanton orchid]

Also the alkaline compatibility is appealing
makes it extremely reliable in event of searching for battery

[twin dew]

Remember that the mAh ratings aren't comparable between them.

Because of the voltage difference, need to be moved to mWh or similar.

[wanton orchid]

I looked it up, for small standard batteries it's still lower than nimh (even if not a lot)
also have higher self discharge
less stability
and is more costly

[twin dew]

The self-discharge is the other way in most sources at least.

Li-Ion having way lower than NiMH.

3% vs. 30% or so.

[wanton orchid]

this is actually in my requirements
user must be choosing it's batteries freely
it can even use it with only partially battery filling (but power limiting)

you can get a alkaline on the floor
put it single in
and you have still enough lighting for finding you keys under your bed
or getting to that car fuse

or putting up your camping inflated bed

it even use both AA and AAA
so whatever you find will do

[twin dew]

I do in fact have a flashlight that can take 3x AAA alkaline (with holder) or single 18650 Li-Ion (with sleeve).

[wanton orchid]

that's nice

3 goals :
not limiting
absolutely reliable (not environment or context dependent)
most compact possible (practical pocket use mandatory)

everything else is equilibrium

[twin dew]

And Li-Ion works much better at low temperatures than NiMH. (near and below 0C).

[wanton orchid]

I didn't find much info on this

the nimh I looked up are rated for down to -20C operation

and I don't trust lion on your car cockpit under sun
after you throw the light to your friend 50m away at camping

(not recommended, you could hurt your friend badly)

[twin dew]

Yes, they work, but the voltage and capacity take big hit after 0C:

But so does the Li-ion too, trying to find comparable chart.

Lot of charts, but which would be apples-to-apples.

So similar.

That is for specific 18650 2000mAh cell rated for -40-85C

[wanton orchid]

hte graph looks quite the same

[twin dew]

Yup, was wrong.

[wanton orchid]

only Li-on allow to have more room for power conversion

already high V

[twin dew]

Part is just that the voltage drop is higher as percentage.

[wanton orchid]

would need 0 point graph to compare fairly

[twin dew]

And that 0.2C discharge is IMHO pretty slow.

AFAIK the difference would get bigger with higher rates.

[wanton orchid]

kind of stuff boring to calculate tbh, I just find Ni-mh standard battery is more available and more stable usually

it have other advantages than current

as I said for everyday ligh use, 0.2C is enough

5C is 4000lumen

you can do thing at ~300lumen

[wanton orchid]

fair, I still think Li-on have other problems

[twin dew]

But seems there has been reinvigoration of NiMH research since NiCd was outlawed for most uses in EU.

And they have gotten much better from what I remember 20 years ago.

Still got replaced by Li-Ion in almost all niches already.

[jagged snow]

Except EVs, for some reason

The battery tech with just about the worst degredation properties and we're going to stick it in a car that spends most nights plugged in'

[twin dew]

Most EVs use some form of lithium batteries.
Just some holdouts still clinging to NiMH.

[jagged snow]

Toyota just built a massive new nimh fab in the US

And are launching a new ev platform on nimh

[twin dew]

Yeah, Toyota is holdout.
But they also try to keep Hydrogen alive etc.

No-one else is doing NiMH anymore AFAIK for cars.

Mainly it is about what specific Li-Ion composition you use, or if you go LiFePo instead.

And even Toyota has used Li-Ion in some models, including Prius.

[edgy hazel]

LiFePo? More like Life Poo

[wanton orchid]

btw Baldur, I'm also planning for self heating in low temp conditions
as anyway the light will get hot, and I want battery temp monitoring
its not that hard to have accessories to increase battery thermal insulation
and let it heat up in the cold

that way it can even be used at -40°C

also led efficiency increase with cold

[edgy hazel]

First print with a 1mm nozzle went well...

I think I'll stick with vase mode for that one

Shit is slurping up filament too

[charred pewter]

that looks ... intentional

[edgy hazel]

I wish

[charred pewter]

how did it even do that ... was it just a kink in the filament spool that it came around at each time ?

[edgy hazel]

that, my friend, is called the z-seam

[charred pewter]

z fighting !

[edgy hazel]

it's where the printer starts/stops a layer/line

[jagged snow]

use better slicer settings

[charred pewter]

ah

[edgy hazel]

uSe bEtTeR SlIcEr sEtTiNgS

[jagged snow]

1mm is tough to make pretty no matter what

And it doesn't matter much for gridfinity anyways

[edgy hazel]

shut up. I know. I don't wanna learn big nozzle shit. Vase mode works and that's all I want 😭

[jagged snow]

I mean all I'm suggesting is set z-seam to random and be done with it

[edgy hazel]

that was gonna be my next try, but after that... I'm out. Back to .4mm

NEW GLORB

[charred pewter]

teh heck

[edgy hazel]

only AI stuff I support tbh

[edgy hazel]

nah fuck 1mm nozzles holy shit

[wanton orchid]

I just thought of something
if you know beam steradian, and you know lumen
then, knowing that lux is actually just lumen/m²
it may be actually less error prone and more straight forward to just translate lumen+beam_steradian into throw

I should work on this

that would become the easy no error way

oh wait, I just noticed it would still not take into account beam initial size

my bad

it would probably simplify to
sqrt(candela/lux) anyway

Candela =　Lumen/BeamSteradian
lux = lumen/m2
candela/lux = m2/beamsteradian
beam steradian = m2/r2
candela/lux = m2 * r2/m2 = r2
sqrt(r2) = r
r = (fake)throw

[edgy hazel]

Bro about to calculate the mass of Unobtanium

[maiden coyote]

Trying to fix cat 5 in a crawl space because of rodents by using a couplers and I put one of the connectors on backwards...

Don't have enough cable to do another one.

[steel peak]

wonder if anyone made LCARS like for integrated home

majel barrett surely said enough words for AI to learn it right

[winged valley]

MARIE makes assembly coding fun ngl

[maiden coyote]

What do.

I wrote this, it normalizes any whole number to 10 in increments or decrements of 1

In the grand scheme of things this is super duper ultra basic but still fun

[winged valley]

MARIE is "Machine Architecture that is Really Inuitive and Easy" its meant for teaching how computers work on the lowest levels

[wanton orchid]

just tell people back to transistor

[maiden coyote]

It's probably not easy enough for me sadly. I'm pretty much an idiot when it comes to that stuff.

[wanton orchid]

and then binary
then addressing
then instruction, and everything lights up
once then you add clock

then you start learning assembly, then C

then you finally get how shit java is

[maiden coyote]

Can't believe I crimped the cat5 connector on backwards in a place where it can't be cut and redone.. I ended up crimping the other side on in the same assbackwards mannor and it seems to work :3

[wanton orchid]

how did you locked yourself into this ?

I mean it really cant be redone ?

[maiden coyote]

it cannot be redone.

[winged valley]

Technically it doesn't matter how the connectors are wired as long as its the same on both ends but

Did you at least avoid crosstalk

[maiden coyote]

not unless I repull the wire.

no idea. I did the best I could with what I had

[wanton orchid]

only if pairs are respected still

[wanton orchid]

if you never mix the 2 orange cable things with the 2 green cable thing, then you are good

[winged valley]

That's why I said technically. Electrically speaking all that matters is you have the same connection wire-wire

[maiden coyote]

instead of orange, stripe gn, blue, solid green, brown

[winged valley]

Messing up the twisted pairs adds interference, but might still be usable (at 10/100M lol)

[maiden coyote]

it's brown, solid green, blue, striped gn, orange

[wanton orchid]

if your cable is longer than few meter, it can be absolutly catastrophic

[maiden coyote]

since it's in the middle of a run. I doubt it'll matter.

[winged valley]

Technically

[winged valley]

That's fine

[maiden coyote]

cable is 25 meters long.

[wanton orchid]

this is not like DC, the pairs need to be pairs and twisted to transmit signal

[maiden coyote]

I'll take it lol

Yeah, but at a connector, they're no longer twisted.

[winged valley]

Yeah that wiring is fine, the little plastic insulator between the pairs would prevent any issues from wiring it backwards like that

[maiden coyote]

and you can have like 10 patch panels on a run and still push 1gbps

[wanton orchid]

I dont care, if you mix between pairs, the signal wires will be split, and pairs will not exist anymore
it's only good if you didnt mix pairs

[maiden coyote]

Yeah, I didn't mix pairs.

[wanton orchid]

then its completly fine

[maiden coyote]

the tester would fail it if I did. I think

[winged valley]

You'd have inconsistent results

Also dang you got that nice premo tester

[maiden coyote]

neat tester and it's only like $100 usd if you do a lot of cat5 and you don't have one. it'll measure the length of wire and tell you where the break is

[winged valley]

My company is a one man army rn so probably not gonna be doing a lot of cabling

[maiden coyote]

in my case, it told me pairs 3/6 were 80ft, and all the others were 26ft.. stands to reason there's a problem at 26ft.

[wanton orchid]

connecting pair 1 into pair 2, and backward, and changing in-pair wire 1-2 -> 2-1 -> 1-2
is completly fine
but if you do
a1 a2 b1 b2 -> a2 b1 b2 a1
its completly broken

[maiden coyote]

not much good when you've got attics and crawl spaes.

[winged valley]

So how does crosstalk mitigation through twisted pairs even work? Without researching it my intuition tells me it staggers the bits across each wire

[maiden coyote]

because the pairs are +/- pairs

[winged valley]

oh

[maiden coyote]

so any emf that would be radiated is canceled out.

[winged valley]

Wait so then RJ45 transmits over 4 data lines?

[wanton orchid]

if you mixed, the signal pairs goes into some other physical pair wires
its completly broken, because its not dc at all, the whole point is signal
which to be transmited is wave of some sort
here it is pulse
the pulse follow wires, and are twisted to keep equilibrium and reduce external tension interferences, so the signal stay the same
its basically a wave between the 2 wires

[winged valley]

So the only differences between it and USB2.0 is 2 more data lines, shielding, and signal frequency?

[maiden coyote]

I think so.

[wanton orchid]

if they go in others twisted pairs, its just completly throwing it out the window

[maiden coyote]

it transmits over 4 pairs or 8 conductors.

so it's technically 4 usb cables plus the network stack :p

[wanton orchid]

the coding is not the same

[winged valley]

Yes I know the protocols aren't the same I was talking about physical difference

[wanton orchid]

I didnt say protocol, I said coding

protocol is on top of signal coding

[maiden coyote]

cat6 and cat 7 are pretty close to usb cable wise.. as cat7 has each pair shielded + an outer shield around the cable.

my mistake just cat 7

[winged valley]

Isn't 5e also per pair shielding or is that just a divider

[maiden coyote]

you can get cat 6 with a shield around the cable. and you should if your cable goes outside

[wanton orchid]

network cables are completly tuned for long distances

as do the signal going on it

[maiden coyote]

long distance being 100m and then repeaters every 100m up to 1000m

[wanton orchid]

usb fade out at 3m
network cables fade out at 150m

[maiden coyote]

100m for poe & 1gbps

[wanton orchid]

for basic spec

you can go further with good cables and/or network equipment

you also can go further with same basic spec but have bad performance

[maiden coyote]

ubiquity yelled at me in the design center when I gave it longer than 100m run so I just assumed it's 100m

[wanton orchid]

that's .. weird/stupid

maybe they just dont want to warrant you for problems with that as this is out of basic spec

[maiden coyote]

also if you're doing cabling for a customer you really want it to work, and work right.. so going back and saying I ran a cable too long and now you need a repeater looks really bad.

poe can also be picky

[wanton orchid]

for instance my intel nic can do 100m 5e 10G, when 10G is only specced for 6 and above
it can do 150m 10Gbe with 6a

it can do more with 1Gbe

[wanton orchid]

poe is MORE peaky

when it comes to length

because it actually have power loss in the wire

at some point it cant power the end equipment

because all the power is lost in the wire

[maiden coyote]

that's probably why ubiquity design center got mad over 100m.

[wanton orchid]

increasing power to compensate can be a fire hazard

its completly forbiden by spec, for electrical and domestic safety reasons

(its not likely ofcourse, but no spec wants to take that risk)

[maiden coyote]

yeah to my understanding the switch and device negotiate a maximum power, such as 10W, the device can use 9.8W without issue, but it cannot exceed the maximum of 10.

[wanton orchid]

and the powering device cannot exceed like 12.5W

[maiden coyote]

100W I think :x

[wanton orchid]

(example)

[wanton orchid]

no, thats for the most powerful spec, and its at the limit of standard domestic wire limits

if you negotiate 10W it cant go above 12.5 or something

[maiden coyote]

gotcha. yeah, so whatever voltage drop there is.. it won't compensate for it.

[wanton orchid]

it will by spec, but not too much

[maiden coyote]

poe is like 48-57V for most things, which puts it at about 1A on poe++

[wanton orchid]

wikipedia :

[wanton orchid]

yes, twisted pairs are not large

[maiden coyote]

I think poe++ uses all the pairs to deliver power though

[wanton orchid]

but not equally

[maiden coyote]

so you have 24x4 and 24x4 which gives you an effective awg of 21 roughly

[wanton orchid]

note how maximum power spec allow for up to 20W lost in the wire

which is a lot

[maiden coyote]

the only device I have that needs more than 5W is a switch that provides more poe

[wanton orchid]

poe passthrough ?

[maiden coyote]

but for ap's and cameras.. 99% of those are using roughly 5W

[wanton orchid]

this is neat, yet to see one irl

[edgy hazel]

wait until you find out about raspi hats 😄

specifically the POE one

[wanton orchid]

25W raspi5

[maiden coyote]

poe in, passthrough poe out.

[wanton orchid]

iirc latest netgear wifi ap goes up 35w

[maiden coyote]

yeah, and the newest unifi ones have a built in cooling fan

[edgy hazel]

the basic one from raspi itself can only do 12.5W 😦

[maiden coyote]

I was thinking about getting a raspi poe cluster.

[wanton orchid]

they are working on the 5 version poe+

[edgy hazel]

inofficial ones already exist too

[maiden coyote]

I have plenty of extra power

[wanton orchid]

I like the idea of having in-network single wire raspberry 5 netowrk controler

[maiden coyote]

store.ui.com/us/en/pro/category/all-wifi/products/u7-pro 21W of poe power consumption

[edgy hazel]

I'm about to get 2 for my 2 model 2b

simply because of the one cable thing

[maiden coyote]

only need to run one cable to your raspi's.

you can get something like this

[edgy hazel]

yeeessss >:)

[quasi citrus]

What is a use case for this?

[wanton orchid]

it looks fat compared to the announced official one

[edgy hazel]

one for your 3d printer, another one for your 3d printer, one CA, one running cronjobs 24/7

[wanton orchid]

oh

[quasi citrus]

Feel free to DM the link if it was for me

[wanton orchid]

www.raspberrypi.com/news/designing-the-poe-hat-for-raspberry-pi-5-compact-efficient-power-and-networking/

[maiden coyote]

raspi cluster. so lets say I need to host a wireguard sever to a specific vlan, that would be the way. another one could serve as cloudflared tunnel server so you can punch through a cgnat. You'll likely need a usb ethernet adapter for that pi. ( if any of you smart people know how to trunk vlans through a rpi let me know)

[wanton orchid]

wht

isnt rpi linux

linux vlan support is native

[maiden coyote]

you could also setup another one with as a dns server with pi hole

I wouldn't know how to do it.

[wanton orchid]

just do ip li ad li BaseName VlanName type vlan id 876

[maiden coyote]

I'd also have to configure my switch to do it too.

or no? I'm kind of new to that stuff.

[wanton orchid]

yes

[maiden coyote]

I thought so

[wanton orchid]

vlan are not network features, they are multiple network multiplexing

[edgy hazel]

or just go untagged

[wanton orchid]

so you have to use the switch features and switch must be aware of it

[edgy hazel]

let the switch tag your shit. 10000 times easier in a homelab

[wanton orchid]

thats not how it works when you specifically want a trunk port

but for other part of the network yes

[edgy hazel]

trunk

[wanton orchid]

just PVID / Untag them

[edgy hazel]

on a pi

[wanton orchid]

with their specific vlan

[wanton orchid]

yes, why not ?

I was just answering wolfgrimm

[edgy hazel]

tbh I'm still used to rpi 2b speeds. This thing will shit itself and die if I press the keys too fast

If it receives packets from two different vlans it'd probably die

[wanton orchid]

depending on switch vendor, the tagged port on the left may be called "trunk" port

but I personally prefer the real setting, where you just put whatever port you want with tagged or untagged settings

Note: default vlan id of switch ports are important
because the equipment connected to it are not vlan aware, so they do not tag their frame, and so their untagged frame must be identified for the same vlan

[wanton orchid]

put the exact same vlan id, as you setup on your switch, its physical id
it must match
it will create virtual interfaces in linux which will just tag the frame on the main link interface
and read frame with the same tag back

in my example the vlan id is 876 obviously

wolfgrimm, waiting on your feedback

[maiden coyote]

so select the vlands I want the port to be tagged with and press save

so native vlan to none, and select the two vlans I want to trunk to the pi.

I don't have a pi to do this with right now. but I'm going to save this for future use, I have fiber.. but my fiber doesn't seem to be the most reliable connection there is. I'm getting high latencey alerts at around the same time every few days.. and sometimes It'll just die for about a miunte.

[wanton orchid]

thats a single port setting there ? or is it the vlan setting panel ?

[maiden coyote]

single port setting

[wanton orchid]

so I think "native vlan" may stand for Default vlan (id) of the port?

[maiden coyote]

I think so.

[wanton orchid]

tagged vlan management stands for access controling the vlans

basically allowing or refusing untagged or unknown vlan tags

[edgy hazel]

native vlan is untagged. So the switch will assign the frame a vlan tag

[wanton orchid]

tagged vlan is you select all the vlans you want the port member of
and it will automatically tag every frame of these

[maiden coyote]

and that should limit the pi on that port to the cloudflared tunnel, and the secondary wan of my gateway

[wanton orchid]

so for pi
you dont touch native vlan
you put custom for tagged vlan management
and you select the 2 or more vlan you want to be sent on your pi with tag

and pi side you ask it to read the tag for those on virtual vlan interfaces as I already shown

[edgy hazel]

Iirc (and correct me if I'm wrong) unifi handles it a bit differently. Native Vlan sets a tag and the other options are just allow/deny other vlan tags (and doesn't modify them)

[wanton orchid]

so let say you select tagged vlan 45 and 257 on this
you can in pi do
ip li ad li BaseIfName VlanWhatever type vlan id 45
ip li ad li BaseIfName VlanOther type vlan id 257

[maiden coyote]

that seems fairly straightfoward.

[wanton orchid]

and communicate with these vlan by using VlanWhatever and VlanOther virtual interfaces

[maiden coyote]

that's what it says when you hover over it.. so if none is selected then only vlans that are tagged under custom will be allowed

[wanton orchid]

on the switch any port you want simply connected to the vlan you want, you just
set the "native vlan" to it

[maiden coyote]

and tag the second vlan under custom

[edgy hazel]

no it can only tag one vlan

under custom you allow/block specific vlans that are sent from the host

[wanton orchid]

what do you mean herg, if you talk about adding tag to incoming untagged its just the "native vlan" thing

[maiden coyote]

it lets me select them all

[edgy hazel]

which will act like the allow all option

[maiden coyote]

ah alright

[wanton orchid]

it specifically says that it will tag every vlan in "allow all"
and you can set per vlan in "custom"

[edgy hazel]

iirc it just doesn't drop them and tags all untagged packets

tagged packets are still sent to their previously tagged vlan and aren't modified/tagged

[wanton orchid]

untagged packets are not part of vlans unless its the native/default vlan you setu up

[edgy hazel]

yes and you tag a packet via the native vlan option.

[wanton orchid]

thats what I said

[edgy hazel]

tagged packets are still sent to the vlan that was tagged in the packet originally

[wanton orchid]

but you seem confused by the other vlan options,

obviously

[edgy hazel]

I am not

but thank you for assuming

[maiden coyote]

ui makes it look simple and confusing

[edgy hazel]

still better than cisco lmao

[wanton orchid]

you literally said that it will not tag tagged packets

sounds like you are trying to add confusion

[maiden coyote]

I think I've got the jist of how to set it up.

[edgy hazel]

yes if you set the native vlan option

[wanton orchid]

the native option is only for untagged packets

because it is the native option

I dont know what you are trying to explain, nobody said otherwise

[maiden coyote]

so setting the native to none will tag all incoming packets, or will it drop them if they don't match the vlan's specified under custom?

[wanton orchid]

it really looks to me that you are confusing incoming and outcoming packets in what we talked about herg

[edgy hazel]

none will not tag anything and only let the ones that are tagged and allowed through

[wanton orchid]

they will either drop or put it on the default vlan (the one you didnt set up)

[maiden coyote]

Alright, that's what I was trying to accomplish

I don't want unfirewalled traffic in my network.

[wanton orchid]

I'm still scared of if information was understood properly or not

[quasi citrus]

I have trouble following along but that is due to lack of basic knowledge. Very interesting either way 🙂

[edgy hazel]

sometimes you gotta trust the process and the other person. Explain it too much and you'll sound like a condescending ass

[winged valley]

Oh VLANs I'm gonna have to learn advanced networking at some point

[wanton orchid]

I will summarize :
2 packets for port :

incoming packets :
either tagged or untagged,

• if untagged (usual netowrk unaware of vlan)
  it will follow the "native"/unaware/untagged/default vlan setting, sending it on the matching vlan (or default network, you could also call it vlan0)
• if tagged :
  the switch already know the vlan for it, its in the tag, but you can choose if it will accept it or not with "vlan management"

outgoing packets :

• if default network (or hidden vlan0) will push it untagged as expected
• if coming from a vlan, you can choose if the port sends for that vlan, and if it sends (the port is member of that vlan) optionally if it sends it tagged or untagged (but it may not be allowed to send it untagged, as it can be confusing for the connected equipment (but the switch does not care if you know what you are doing))

[wanton orchid]

I prefer sounding like a condescending ass, but you probably already noticed that

[edgy hazel]

I did

[winged valley]

I mean there's a pretty easy way to avoid sounding like a condescending ass

Which is to quickly and naturally say whatever it is

Like it sounds so offhand you were just responding without putting much thought into it

Then instead of being condescending you're just pointing something out / answering a question

So now you have the satisfaction/security of knowing they understand, and if they didn't understand they'll usually say something

[edgy hazel]

and 99% of the time it's not something that's risking lives anyways

[wanton orchid]

I summed up, all the behavior you can tweak on a port

[maiden coyote]

it's neat.

[wanton orchid]

sometimes you do not have the "default untagged ouput" network
because it is either implied by the "native"/default vlan/network
or under control with effectively the vlan output setting its linked to

[quasi citrus]

My pihole in a docker container wants me to learn about it.

[maiden coyote]

when you start doing vlans, you can plug your unfirewalled internet connection into a tagged port on your switch that's connected to all your other devices, but it will only allow traffic from that port to go to your gateway/firewall.

[wanton orchid]

there is one thing security wise to caring for once vlan is setup :
bandwidth and priority control

a contained vlan, can still try to starve the other important vlans

full management switch allow for priority/throttling control too

[maiden coyote]

I've seen the options for that in my switch settings. since I've got what amounts to a overkill home network with a few exposed services, it's one of those that's cool but I'll never use it options lol

[quasi citrus]

I really have to learn how to properly and securely set up a dyndns as a safe setup and allowing internet communication for an app to my home network server. But so far it has been a task I didn't feel up to yet as my information level on networking is good but I feel it is not good enough to be sure it is safe.
I hate it that my tandoor instance (recipe and shopping list program) can't be accessed when out of the house

[wanton orchid]

lot of stuff we talked about sounds overkill for that

[quasi citrus]

Yes. In the end probably all what I need Is done via proper port forwarding on the router?

[wanton orchid]

mostly, and not opening machine firewall too much

the dyndns part is independent

[quasi citrus]

And making sure the port forwarding is only done to that server that only takes communication on that port?

[wanton orchid]

and must be adressed on its own

[quasi citrus]

Yeah but before I do that I want my rest of the setup to be sound 😄

[wanton orchid]

ports can only be forwarded to one machine in home router setup

because they are single ports

on single addresses

[quasi citrus]

I Remember a discussion a few days ago about that proper phrasing 😄

[wanton orchid]

only in firewall opening of the router you can allow for multiple machine port access, because of each machine addresses (ipv6 setup)

but then its not called forwarding

its just opening the routing firewall

it may not be there at all (fully open)

[quasi citrus]

Thank you for explaining

[wanton orchid]

to be honest I dont like literal dyndns, because its very not secure
I prefer provider api safe pocking,
using official api, or using provider software to update the dns

[quasi citrus]

Only knew about Dyn DNS as a solution to my problem. Will have a look at that. Thank you

[wanton orchid]

for instance I have some dns at ovh
and I (re)wrote a python script to manage it (after I took the spine of it on some random github)

the very basic is always the same, you want some client, to tell the provider to update the name to the new address

[quasi citrus]

Should be within my realm of competence I guess

[wanton orchid]

but you do not want anybody to be able to freely update it

so it must use a secure protocol

ovh python script use https

with ovh account created bot credential

[quasi citrus]

How come you ended up with ovh?

[wanton orchid]

because their dns management solution is literally free

and I'm not in the best situation in my life

[wanton orchid]

* the dns itself is not free, obviously

[quasi citrus]

Student at the end of student life here. Money will be there but surely is not atm

[wanton orchid]

btw .ovh domains are accessible

they are not expensive

you can also manage externally bought dns

by asking for the dns server to be the ovh owned ones

[quasi citrus]

~~ 1 €/y for a .de domain ~~: 👀

[wanton orchid]

you can also buy other domain type from ovh

now ofcourse amazon or google have similar services, but I know ovh well because I'm working with it

and I prefer that for european stuff

[quasi citrus]

Yeah makes sense.

[edgy hazel]

if you wanna go .de I do recommend strato. A bit more expensive, but worth it for their support. They know their shit

If I really have issues with dns or other similar stuff I call em

[quasi citrus]

Thx for the input!

[edgy hazel]

(even if it's not their area or job)

[quasi citrus]

This seems to be a first year only thing.

[edgy hazel]

it's always. .de domains are usually ~2€/mo

[wanton orchid]

I wanted a open api for writing custom client to manage my stuff, and I wanted it to be cheap
ovh makes it cant be cheaper
and its just a rest https api
using it from basic python setup is easy

I prefer when you just pay fixed amount per year

for .com its usually 15euro/y

iirc

[edgy hazel]

Basically every shop offers that yes

Locking people into a contract 101

[quasi citrus]

My brother stole my lastname.de though 🙈 he is my younger brother. So shame on me for not being fast enough:-D

[wanton orchid]

you can ask him to give you ruling on firstname.lastname.de then

[edgy hazel]

Go for lastname.com and SEO the shit out of your site for payback

[quasi citrus]

Haha, love that first.last.com idea. He offered other options. somehow that idea didn't come to our minds yet

[winged valley]

Why has nobody put something like this into a contract

"According to a survey issued to N people, it has been established that the layman's understanding of these contract terms is blank. This layman's understanding ties into our terms by blank blank blank. Any deviation or attempt to find and exploit a "loophole" in our terms which is countered by the layman's understanding will be denied"

As I was writing that, I think I know why

It would be reaaallllyy hard to write a clause like that

[languid gulch]

yea, they're not about to idiot-proof a contract. the idiots are who they're trying to exploit with the contract

[languid gulch]

so, because of course this is how things happen, tho thankfully it ended up being nothing

had the new car for less than 2 weeks, got rear ended

no visible damage, more of a shock since it was the first time (somehow) it's ever happened to me

couple days later i noticed that one of the fender wells had a weird bit of exposed car paint, looks like the bonk might have busted a couple clips

so i get under it to look a bit closer, sure enough, yup, another clip missing that holds the rear bumper.

and then i see the chunk of metal sticking out of the tire

[jagged snow]

Oh no

[languid gulch]

best news: metal was a construction staple, while it punched thru all it needed was a patch, & the bumper damage is limited to the license plate mounting screws scuffing up the bumper

so between a rear ending & a hole in the tire it was a $25 fix. bumper clips from amazon & it'll be good as new

also i got get a decent look under an electric car for the first time

besides the turn signals & a couple of proximity sensors, there's nothing under the bumper

this could have easily been a $3000 day, so i'm happy

[jagged snow]

That's good at least

Body work gets pricey fast if you have to take it in

[languid gulch]

yup, had the guy give it a once over, & he did point out that it had been bonked before enough to need a paint job

but the bumper was original

and unless you're a pro you basically couldn't tell

used car, i wasn't expecting perfection

& it wasn't enough damage for anyone to claim anything

[twin dew]

The default pinout is already stupid.
Doing the same stupid pinout in opposite order doesn't matter at all, when both connectors are the same.

[twin dew]

The 100m distance limit is because of timing.
Not because of fade.

So if you do ethernet cable longer than 100m, it won't work because the time for the signal to traverse the cable will be too long.
Not because the signal degrades too much.

But seems that timing thing doesn't matter with current Point-to-Point links, only with old HUB using shared segments.

So with full-duplex point-to-point links (computer to computer or computer to switch) that doesn't matter anymore.

In HUB using network it was limit between two farthest points in the same segment, where HUBs just connect cables in the same segment together.

So:
Computer - 30m - HUB - 30m - HUB - 30m - Computer would be 90m segment.

But as no-one is even producing Ethernet HUBs anymore...

[wanton orchid]

yep I was not thinking about true hubs at all

there is no static timing communication in the protocol
so as the signal/data lines follow the signal timings
receiver does not care at what exact time it was sent by transmitter
so you can have infinit long cable as long as signal is going through

appart from practical limits, like management layer who expect direct link to have negligible transmit time

as long as it's under 1ms
it's ok

[twin dew]

With the old style there was the limit for the collision detection window which caused that timing limit.

And I was misremembering what was the source of that timing limit in the protocol.

Because I just remembered they had to do changes when moving from 10Mb to 100Mb to keep the same max distance limit in the protocol to some timing thing.

But at 100Mb/s, HUBs were still a thing, not so at 1Gb/s anymore.

[midnight osprey]

guys, any idea why some of these options are blocked by other apps?

[twin dew]

Just showing where the other ones are slotted in at the moment if you don't place the thing on that slot?

[midnight osprey]

nice thought but they are not in those slots

not even on the same monitor

its like they are locked the slots down

happened about a month ago and persists between reboots, not just sleep

[wanton orchid]

it's not where it is
it's just where it will go
just select the one you want and it'll go away/elsewhere

[twin dew]

Or go into Settings and disable the thing where Windows autoplaces other apps based on your manual placement.

Which is on by default IIRC.

Or was it just that it asks what you want to place in the other slots?

[dire igloo]

The missile knows where it is...

[edgy hazel]

Gridfinity fucks

[pure karma]

by knowing where it isn't

[edgy hazel]

What is bro doing

He just went ~

[sterile plinth]

any suggestions for a 75% keyboard under 90$, ideally 2.4ghz wireless

keychron v1 max matches all of these criteria but the framing around is a bit too big and i think it would annoy me

[edgy hazel]

Didn't you ask that already a few days ago?

[sterile plinth]

yeah i was already looking at keychron ones but this kinda threw me off

[twin dew]

"2.4GHz wireless" means what?
Because there isn't one tech.
And it really doesn't matter what band the wireless system uses if it needs specific dongle.

[sterile plinth]

not bluetooth

[twin dew]

2.4GHz is just one of the "free for all" bands available.

[sterile plinth]

dongle pretty much

for 1000hz polling rate

the keychron k2 pro is much smaller the way i like it but only bluetooth which is like 80hz polling

[twin dew]

So what you wanted was "Non-bluetooth, 1000hz polling supporting wireless connection".

Not "2.4GHz wireless", which includes bluetooth and various solutions that don't do 1khz.

[sand saddle]

Doubt there’s any bluetooth 1000hz implementation anyways

[sand saddle]

You need a wrist rest anyways

[sterile plinth]

yes

[twin dew]

Yes, the "non-bluetooth" part was redundant.

[sterile plinth]

i guess thats just the laymans term, anyway if you find anything of that kind let me know~

[twin dew]

That is just bullshit marketing term that doesn't mean anything in reality.

Just that almost everyone uses the 2.4GHz ISM band as it is free-to-use.
Including 2.4GHz WLAN and Bluetooth, and lot of other stuff.

As the lower ISM bands are much less suitable, and the 5GHz ISM is costlier to implement and has less penetration.

[sterile plinth]

ok what i meant is 1000hz stop bullying me about my lack of wireless stuff language 😭

just bluetooth is always associated with low polling rate

[mental oriole]

Wired superior

[soft bloom]

like, why need wireless in a first place?

[edgy hazel]

Yeah wireless keyboard is pretty useless unless you do either a lot of business travel or want to game on your couch with a keyboard for some fucken reason

[soft bloom]

but gamepad is better for couch. you wont get nice expreience with keyboard without table

[pure karma]

even for a mouse there is only personally one scenario where there are more benefits than cons whit wireless and thats my laptop

[edgy hazel]

nah mouse is a different story and is 100% preference

the cable is fucking annoying on something you have to move ...

[twin dew]

Not when it is "mounted" properly.
And then you don't have to care about charge.

[tough owl]

For those of you with like comptia certs and alike which ones do y’all recommend start with and then build from there? Summer is starting and I’m looking to fill my time and try to make the most of it

[twin dew]

Almost all of the various certs are just pure cashgrabs.
And only matter if someone mandates employee to have one.

[tough owl]

my school highly suggests I get certs in some areas and looks for them when hiring employees

[edgy hazel]

I did but thank you. I just don't like it

hence the preference part

[jagged snow]

I'm currently working on cisco ccst networking

Will be about 175 all told

I prefer it to the comptia certs since it's lifetime, so no renewals

[soft bloom]

i feel like there's simply very little wired mouses left

afair wired vertical mouse is rare

[edgy hazel]

no? The majority of wireless mice can also be used via cable

also there are still a lot of """"esport"""" mice which are cable only to reduce weight

[jagged snow]

There are also a lot of """"esport"""" mice that are wireless to reduce cable drag

[soft bloom]

my local market tells me otherwise.
also, not so bad i guess...
https:// hard.rozetka.com.ua/ua/mouses/c80172/

[jagged snow]

Oh no, only 27 thousand

[edgy hazel]

just because it's wireless doesn't mean it can't be used wired

[soft bloom]

vs 30k

but less than 1k combined

[jagged snow]

Wow... 10% fewer

[soft bloom]

than what is "combined" for?

[edgy hazel]

I have no clue, but that number is 100% wrong

[jagged snow]

That means there are barely any wired mice out there at all! You'll never be able to buy one!

[edgy hazel]

prolly just bad categorisation

[soft bloom]

if i sleect single store (meaning definitely no duplicates) - relation becames 3 to 1 for wirless

ok, to be fairthis should be conducted on something like amazon

but that would not be my expreience a was talking about

[dire igloo]

Wireless is becoming more and more popular, but wired is still being kept for lower latency, infinite battery life, lower weight and lower cost

[jagged snow]

Not to mention better durability

Rechargeable wireless mice can have the battery go bad

Especially if they stay plugged in most of the time and only get unplugged occasionally

[soft bloom]

easier to have accumulators

[twin dew]

Accumulators?
You mean capacitors?
Way too high self-discharge.

[jagged snow]

And too low energy density from a weight perspective

[jagged snow]

Accumulator was the old name for them in the states back in the day

[dire igloo]

Could be Denglisch too.
"Akku" (Akkumulator) = rechargable battery

Not really the proper technical term for it tho

[soft bloom]

rechargable batteries

[soft bloom]

funny, i was convinced that i saw "accumulator" on the batteries themselves, but only found single one, and it was written as "accu", without the rest of the world

[twin dew]

And in English, Accumulator is not synonym for rechargeable batteries.

[soft bloom]

recently, in other english discord, i got assured that "acum" is understood. but, to be fair, there it could have been replaced with "capacitor"

acum is funny word to write in the modern state of internet

[twin dew]

WTF is "acum"?

never heard of as a word.

[soft bloom]

short for accumulator

hehe, i made that ("acum") up probably 🙂

but its exactly how i would refer to rechargable battery in my tongue

[jagged snow]

Nope, I've sen it as well when working with large scale hydraulics

[twin dew]

Accumulator is thing in hydraulics and pneumatics.

[jagged snow]

Specifically that shortening of acum, accu, or accum

[soft bloom]

people will short the heck out of words if given the opportunity

that's what kin-dza-dza teaches us about

[twin dew]

But any such thing will be jargon for LONG time.

And bad idea to use outside the specific niche.

[dire igloo]

The result of male self-satisfaction

[dire igloo]

Y'all'd've

[jagged snow]

Oh that's interesting

[twin dew]

Yeah, mainstream English is weird and doesn't have separate words for primary batteries and rechargeable batteries.
Both are just batteries.

Compared to most other languages I know of.

[jagged snow]

I never really thought about that, interesting distinction.

[twin dew]

Finnish too has "akku" for rechargeable ones and "paristo" for primary ones.

"patteri" was common-speak, but wrong word.

[edgy hazel]

currently printing one of these badboys for one of our old server @dire igloo

[dire igloo]

Nice

My sister went to a job expo once, came back with a BND cloth bag

Still jealous of her for it

[charred pewter]

speaking of 3d printing ....

[mental oriole]

[night girder]

Read today: first emulator to hit app store is already removed

[charred pewter]

i still have a teekwood drawer holder full of original floppies (the 3.5" kind)

[night girder]

www.macrumors.com/2024/04/15/apple-removes-igba-from-app-store/

[twin dew]

But 3.5" disks aren't even floppy!

[charred pewter]

how bout a game emulator that lets one play all the 32bit games they lost during the 64bitageddon

[willow pike]

it was an unauthorised copy of someone else's emulator and probably had heinous ad tracking shit stuffed into it

[charred pewter]

most likely.... sketchy as shit devs always trying to sneak filth in

[night girder]

if it flops. It's a floppy disk.

[charred pewter]

i always thought the 3.5" disks were "hard disks" ... and the 5 1/4" were the actual 'floppy disks" 😄

[night girder]

it has to flop to be a floppy disk

[charred pewter]

took me awhile to realize ...

and when 'hard disks' came about, i thought all they were was a stack of floppies in a harder container ... then was equally confused why the 3.5" were not also 'hard disks' 😄

[edgy hazel]

SSDs must have confused you a lot

[night girder]

not probably, it had 😂

[visual tree]

Wait till young generation finds out about the punched cards

[night girder]

but the real crime is, it weren't apple adds 😂

else they might have gotten away with it.

[night girder]

or cd's - It's going in the same direction as floppy disks. Eventually.

Cloud service for music. Cloud service for movies.

[visual tree]

I wonder if there are still shops nearby renting DVD's and VHS

[night girder]

Games downloaded from the cloud.

[visual tree]

or they are dead already

[night girder]

It died in my country. You barely find them.

There was some news a while back of ubisoft pulling the plug from a game.

It also dissapeared from people's game library

I read some arguments who said: "Well, even if you have a CD of the game, doesn't mean you can still run it in 20 years".

[mental oriole]

The crew got nuked from peoples accounts, because ubisoft be like... buy the newer one

[night girder]

and other people are just pissed. "I paid for the product, you cannot take it from my library".

[night girder]

This one!

[twin dew]

But that is on the CD haver then, not the publisher.
So very bad "comparison".

[visual tree]

Just read the owner of the last shop in the capital city renting DVD's and VHS was found dead in his apartment last year 👀

[night girder]

Huh?

[twin dew]

I mean the person saying that was idiot.

[night girder]

Why?

I cannot install age of empires (still have the disks) anymore on W11.

[twin dew]

Yes, new HW or OS cannot always run the old game.
But you can keep the old HW and SW.

But if the downloadable game is just removed, there is nothing you can do.

Except warez.

And various solutions to running old games have been developed that the game owner can deploy.
No such luck if the game was just removed.

[edgy hazel]

I mean you could probably install the missing libraries and also run in compat mode if you'd like to have more security holes than d-link

[night girder]

People just don't like that someone else decides over a product you own.

[twin dew]

Because if they can removed like that, you didn't actually own it.
Even when it was "sold" and not "licensed".

[night girder]

We don't own games. For a long time now.

[twin dew]

Not anymore basically.

[edgy hazel]

no you can definitely own games

[night girder]

We pay, a "hire" fee to play the game. Or something.

[twin dew]

But not being able to run old physical game you have, isn't in any way comparable to situation that "sold" game is just removed.

[night girder]

We can. But most of us don't. Steam goes bankrupt = RIP libraries.

[edgy hazel]

🏴‍☠️

[night girder]

Yeah, with all the added risks.

[edgy hazel]

risks like stealing my data which everyone else is already doing

[night girder]

Let's just hope this is not the dawn of a new age, and other developers start doing to same

Removing older games from libraries when they release a new game to push sale.

[edgy hazel]

I mean they don't have to straight up remove it. They can just kill the servers which EA has been doing for years

[night girder]

I did read that the Crew was barely played.

[night girder]

If dedicated servers that's a non issue.

Probably the reason why TF2 is still alive.

[edgy hazel]

EA should give you enough of a hint

[night girder]

and that's why I try to buy games for dirt cheap (the sales on steam)

Slowly the new price will be 70 euro's for a new game. Fuck that.

[visual tree]

Lmao 🤣 https://www.youtube.com/watch?v=tWFiCtvhwec

[night girder]

and when they pull the plug, poof game gone 😄

[visual tree]

Can't believe they made such an amateur mistake

[night girder]

oh, and for the other 50% of the game, you might need to wait a few years.

And there is a slight change the developer will never finish the other 50% of the game because they need to start working on sequel

That's AAA games to me in a nutshell. A huge freaking risk.

[tough owl]

What a shame 😔

[night girder]

I wonder how this will go, I have a bad feeling. But maybe I am wrong.

[dire igloo]

I like Helldivers 2 for what it is.
Great mix of live service (constantly new content, grind is being rewarded) and "F2P"/casual playability

Also "only" $40 for the game

[night girder]

I have a issue with it.

[dire igloo]

And it's fun and looks great, doesn't run well on anything tho

[night girder]

This is cool. https://www.youtube.com/watch?v=tLcnJEMnlTs

[maiden coyote]

Bed not level?

[edgy hazel]

Nah everything is straight af

[charred pewter]

lol yeah ... its not floppy, its not hard, its ... its .... MAGIC

wasnt there a short stint of 'crystal drives' ...

[wooden vessel]

I've been following the ocean cleanup for years. They are doing amazing work.

their river interceptors are very clever as well

[night girder]

Yes, and the background of the company is also amazing. Friend of mine went to the same school in Delft (The Netherlands) as the CEO.

[edgy hazel]

what is harder? "Solid" or "Hard"

[charred pewter]

Hard Scale

[night girder]

They also keep on improving and experimenting. I love it.

[charred pewter]

scratch it with your thumbnail

solid state (immoveable), hard disc (still spins), floppy (totally useless) ...

[night girder]

The other part is, it's also a possitive story. They don't stare themselves blind at the "Why is this happening?" but at the "What can we do about it?"

[charred pewter]

(thats what she said)

[night girder]

And actually come up with a solution that works. In an ideal world, there would be no trash in the ocean, but thinking like that get's us nowhere. This project puts words into action.

[wooden vessel]

My parents were dutch so the accent is always a treat to hear. Their effort to iterate the oceangoing build were great to see, and it looks like system 03 will be launched as they have it, one question is... how many. I was so glad to see them starting with the Dominican for their river project, the amount of styrofoam in their waterways -- seen it with my own eyes -- was astounding

[night girder]

From the video, I gathered that they will focus on 1% of the rivers because they believe they cause 80% of garbage in the ocean. For the interceptors that is.

[wooden vessel]

seven installed in kingston, jamaica. The barricade design in guatemala has caught 800 kkg of trash, it's so OP and yet a drop in the bucket.

[edgy hazel]

kkg?

[night girder]

That's something I was wondering, how much garbage are they removing and how much garbage is added every year

You aren't dutch by any chance are you? Because we have a proverb for this; "Dweilen met de kraan open" 😂

[wooden vessel]

kkg is 1000 kg

[edgy hazel]

oh so tons

[languid gulch]

MEGAGRAM

[wooden vessel]

[edgy hazel]

[languid gulch]

DECAGRAM

[night girder]

Haha, ok 😄

[wooden vessel]

I try to avoid the American habit of claiming cultural heritage that's dim. I like a good rijstaffel and enjoy various other dutch things, and I'm blunt, but these are things i picked up rather than taught culture

mopping with the tap open. i like it

[winged valley]

Americans have many annoying political habits

[edgy hazel]

like a friend of mine who always was like "I'm jewish" and then like 2 years later it turns out he's 1/16th jewish and also an atheist lmao

[winged valley]

Whole country is so polarized its nonsensical

[night girder]

It sounds weird in english, so I wasn't sure if I could just translate it 😂

but yeah, I hope that isn't the case for the ocean project. But it probably is. If they can upscale the project more and more it can make a difference. This is just the seed planted. Hopefully it grows into a forest.

[wooden vessel]

I can't even talk about it without losing my cool.

[winged valley]

Understandable

[night girder]

That's why we don't talk about it in this channel.

[winged valley]

Yeah

[languid gulch]

yup

[wooden vessel]

and it's not even my country, i have to tell my maga republican cousins I DON'T CARE DO U and it sails right over their head

kkk

[edgy hazel]

fuck

[jagged snow]

Also wearing hats too often can cause early balding

[edgy hazel]

FUCK

bro I had blue hair, bleached hair, manbun, I smoke, eat burgers and love hats....

it's so over

[tough owl]

bros gonna be a baller bald person

[edgy hazel]

I won't even have to shave to go bald

just give me like 10 more years and it's all gone

[soft bloom]

i'm confused, why eating condoms is even a thing?

oh...

english words in other languages can be weird

[edgy hazel]

didn't plan on bringing my sex life into my hairline discussion

[soft bloom]

you probably wont need that knowledge, but for some reason, "preservative" is how eastern europe named "condom". and what "preservative" actually means is named "conservant"

[jagged snow]

That is actually really funny

[tough owl]

Translating into other languages is funny

[jagged snow]

@tough owl you like IEMs right?

https://youtu.be/2eOcsAebO1k?si=RmzsDW-U3IeOneHx

[tough owl]

Uh

I was interested in buying some but never did

[soft bloom]

yes. but what is funnier is how my mind casually replaces "preservative" with something i know should be "condom"

[jagged snow]

I can't believe this isn't something we've come across before

[night girder]

it's not a common word

I mean, atleast in english afaik

maybe KEKw uses the word more 😂

[maiden coyote]

Yay water damage!

oh.. that's not good. something disinterested.

[jagged snow]

What's that on?

[maiden coyote]

blue parrot bluetooth headset

[night girder]

blue parrot? 🤨

never heard of it

[maiden coyote]

high end headset aimed towards drivers

[night girder]

ah makes sense

I was thinking gaming headset 😂

[maiden coyote]

this one was almost $300 usd i think the dude said

[jagged snow]

Ah, that's too bad
How'd it happen?

[maiden coyote]

something around there.

[night girder]

not fixable?

[maiden coyote]

I don't know yet. one of the leads on the pic is gone. but I think there's enough there to fix that

there's another component next to it that's broken in half

oh, maybe it's not broke

[soft bloom]

which one?

[night girder]

preservative

[maiden coyote]

I think it's fixed. Yay

[jagged snow]

Cool, glad to hear it

[tough owl]

Nothing like my school hooking up a 4:3 monitor to a 10th gen i7 and Radeon pro wx3200

[languid gulch]

i graduated this century, but i still had to learn how to use microfiche because the university had archive data in that form

[tough owl]

I’ve never heard of that

[winged valley]

4:3 doesnt mean anything

Is it 720p 4:3? Then its funny

[twin dew]

Usually means that the monitor is OLD.

[winged valley]

Usually but shh details are important

[twin dew]

But I'm not aware of any 4:3 monitor ever being 960x720.
1024x768 would be the common near it.

Which is why there are/were so many 1366x768 TVs and monitors, instead of the sane 1280x720.

[edgy hazel]

Weren't like most of the videos CGI anyways?

[twin dew]

No.

None of the Boston Dynamics videos were CGI AFAIK.

https://www.youtube.com/watch?v=HQ1WEiMwV7Y

Basically the movement cannot be motion captured, as the center of gravity etc. is too far off from human.
Movement is way too perfectly real to be manual rigging.
And light, shadows etc. are too perfect to be CGI with any normal process with realistic amount of computing power used to generate.

[soft bloom]

Well, ofcourse, if i need one, i buy it - not talk about it somewhere.

[charred pewter]

its fake ... so was the moon landing ...

[thick radish]

I imagine it could easily be faked today, but not when it was actually shown

[charred pewter]

like all the ships and sets in the original Star Wars were made with CG 😄

(the tech didnt exist back then!)

[twin dew]

No, only the last one is computing power related.
So you COULD render it all with good enough raytracing solution, but the amount of rays and bounces would be insane.

So still way easier to do it real, than with CGI.

[charred pewter]

building physical robots is easier than complex cgi ... hmm ...

[twin dew]

To the level those videos are without any CGI blemishes.

Yes, you could do it with CGI, but not to the level of all-around realism those videos are.

[charred pewter]

i have to wince when i saw the outtakes reel when they would bust a gasket or rip a hose and sparks/fluids spewed out... like ... OUCH ... have to feel for those guys

[twin dew]

That Corridor Crew video goes into the kind of things you would see when you looked closely if it was CGI.

With clipping, shadows etc.

[charred pewter]

yeah

was a good watch .. had to stop watching at the end with the stupid vpn advertisement though 😉

[twin dew]

Reflections, color and light matching...

And like shown and talked in that video, Corridor Crew had made several CGI robot videos that people thought were real XD

And showed artifacts in those as comparison.

[jagged snow]

Spotify keeps telling me that they've detected suspicious activity and reset my password pretty much every week

[winged valley]

Okay I might be dumb but I can't find info on this

Coaxial MHF4 connectors, you know the ones used for wifi antennas on laptops, are they polarized or no

Because I need to splice the cableside connector onto a cable

[twin dew]

You cannot basically.

[jagged snow]

Well yes, but the polarity shouldn't matter if you're actually using it as a wireless antenna

[twin dew]

Without very specialist tools.

[winged valley]

I assumed the pad in the center is signal and the housing is ground but when testing they appear to both be the same connection

Unless its 2 layers

[jagged snow]

You should read up on how radio works

[winged valley]

In between the sheathing

[jagged snow]

Antenna has impedance calibrated to the frequency it's designed to work with, but not much or any resistance to dc

It's more or less just another piece of wire

[twin dew]

Coaxial means the form, inner signal conductor with another shield/ground conductor around it.

With very specific measurements, to get right impedance.

[winged valley]

Oh okay so its 2 layers

Well that sucks

So its impractical to splice then

[jagged snow]

Yes

[twin dew]

And you need to keep those specifics in any connection too.

[winged valley]

Well, it was to fix the aux line on a 2 cable wifi card anyways, so I suppose it will be fine without it

The aux antenna is only for redundancy right?

[twin dew]

Not anymore.

[winged valley]

Oh whats it for now

[twin dew]

Without it you at best case halve the transfer rate AFAIK.

And might make the whole thing just not work.

[winged valley]

o

that's bad

[jagged snow]

And you also loose many of the features required to make it compliant with newer wifi standards

[winged valley]

This is an 8th gen intel laptop so what are the odds of it not really mattering

[jagged snow]

Starting with ac if memory serves

[winged valley]

AC is WIFI 5 isn't it?

[twin dew]

Yes

[jagged snow]

Yeah
Spec has been around since 2015

[twin dew]

Just the name Wifi 5 wasn't around yet when AC came out.

But basically you cannot splice any coaxial cable being used as antenna cable manually.
And mounting connectors in anything smaller than the "full-size" like used for TV and radio is real pain.
And the cable, connector and tool need to match exactly.

From one manufacturers MHF4 connector catalog.

Still needs connector specific crimper tool.

And to get the tiny cable cut right manually...

The tolerances: 0.1mm

[twin dew]

Sorry, +-0.1mm, so 0.2mm total.

[winged valley]

I did the splice

Its insulated at least, 110% not to spec but it IS connected and insulated, so probably better than nothing

[charred pewter]

thats odd ! ... maybe check if the email box you used is in the haveibeenpwned list ?

[winged valley]

Btw I measured the voltage on a Dell 65w barrel plug charger (using probes, I don't have a fancy charger tester) and it said 0.03 volts. Knowing Dell, the charger might be screwey with its output. So should I trust my reading of 0.03V and assume dead charger or is it inconclusive

No internet info on this

[edgy hazel]

Got that custom firmware on my printer now. Shit is banging I have so much control over everything now

[jagged snow]

Email has been in a few big leaks but it's never caused an issue before

[jagged snow]

By the way, you've all seen the new generation of humaniod robot from boston dynamics?

https://youtu.be/29ECwExc-_M?si=F3diNJPitlRCsx3F

Looks absolutely wild

And its movement is starting very much to approach sci fi/uncanny valley

[languid gulch]

it really is amazing how long it's taken to duplicate something as seemingly simple as walking

[jagged snow]

It really is

Tendons and muscles are remarkably difficult to imitate

[gilded helm]

And we're still just really getting started. Even in just 5 years, it's going to be nuts to see the progression.

Even a year from now, the additional movement training data you'll be able to shove into one of those will probably make a dramatic improvement.

[languid gulch]

i know disney decided to add in some uniformed/costumed robots to sub in for actors doing acrobatics

[dire igloo]

What's that name for the paradox where stuff that's easy for humans is hard for computers and vice versa?

[languid gulch]

oof. no idea

[sharp oasis]

Yall want a draken?

Only a small payment of $249,000

(I'm kidding dw)

It's actually $249,000

Who afford these

[languid gulch]

a new cessna 172 is 400-600k

with a waiting list

[sharp oasis]

How the fuck

Is a Cessna more then a J35 draken

[twin dew]

New vs. very old.

[sharp oasis]

What the fuck

[languid gulch]

upfront cost vs maintenance & red tape

[twin dew]

Old cessnas are about 100k.

Flightworthy ones.

[sharp oasis]

Bruh

So it's quite litterally cheaper for me to buy the draken

[twin dew]

Aircraft are EXPENSIVE.
And there is lot of red tape.
And the maintenance is very expensive.

[sharp oasis]

Ofc

[languid gulch]

buy, yes. fly, no

[sharp oasis]

Fly no that thing would one eat fuel

[twin dew]

And maintaining old military jet is either insanely expensive or not possible.

[sharp oasis]

Two I'd need training

[languid gulch]

🤣

[sharp oasis]

As yeah I don't think you avg dood is gonna hold up well after pulling 7gs Ina extended mach turn

Heck I don't think the draken would like that much

[languid gulch]

it'd be like buying an original GT40 for $25k. sure, it was cheap, but also there's no way in hell you'd be able to take it on the road, & changing the oil would be a $1500 job

[twin dew]

No, as in getting it officially flightworthy can cost many times that buying price.
If even possible.

And then each flight-hour might cost 10-50k

[sharp oasis]

Basically millionaire shit

Would make a cool flightsim

[languid gulch]

i can drive about 15 minutes & see stuff just as cool

[sharp oasis]

It'd be cheaper to buy a Wiesel 1A4 that's been demilitarized. And have it shipped here to canada

Like alot cheaper

There's one selling In the UK for god knows what

Goofy goober 5ton tank

[languid gulch]

this was a couple weeks ago

[sharp oasis]

@twin dew so itd need to be inspected again

But has spare parts for the engine

[twin dew]

No, has spare engine.
But many of the parts are calendar time limited too.
Not just use-time limited.

[tribal kraken]

My friend has Ikarus C42 ultra light aircraft with group 3 people. Plane bought used was around 60k€ and license course about 6€ per pilot. Thats maybe the cheapest way into flying hobby in Finland atleast. Some 2-stroke open cockpit ultra-lights would be even cheaper but...

[sharp oasis]

So it's two engines to maintain

For the aircraft and inspection

It's just about cheaper then a new cessna

[languid gulch]

a lot of that stuff was made to be used within a certain amount of time, so god knows if any of it would ever be certified to fly

[sharp oasis]

If say it passed

[languid gulch]

who wants to check the turbine for microfractures

[sharp oasis]

If it fails. Damn that's gonna be costly to fix

[languid gulch]

just a bit

[sharp oasis]

If it's fixable

[languid gulch]

you can't fix that. replacement is the only option

[twin dew]

Well, that is part of the mandated maintenance program, and you don't get to fly it legally if you don't follow that...
Which is why the price per hour of flight time is so expensive, as that includes the maintenance amortization.
Not just fuel and immediate costs.

[sharp oasis]

There's also apparently a airworthy MI24P

Like fully inspected and stuff

But it's more then the draken

[languid gulch]

think i'd feel safer in a Yugo

[sharp oasis]

And I'd need to somehow get the government to not mind the fact I now own a decommissioned attack helicopter

Let alone warplane

[languid gulch]

🤣

[sharp oasis]

The Feds at my door. Hey why the fuck do you have a fully air worthy MI24P in your back yard

Me: I was bored

[languid gulch]

"Revenue Service here. you claimed a $120.000 deduction called "Gigantic Mistake"?"

[sharp oasis]

The CRA coming after me after I buy a draken and helicopter.

[languid gulch]

"How did a 1963 Saab cost you $400,000 in the past year?"

[sharp oasis]

Why is there massive holes in your payche

[sharp oasis]

uhhh it's a really expensive car I. Guesss

;)

They seize my property and find a fucking airplane

[languid gulch]

take it out on the road, it's a classic saab

claim it as a luxury company vehicle

[twin dew]

That is the point that most of the plugs are both.
So you can use the cords in either area.

A hybrid E/F plug (officially called CEE 7/7) was developed in order to bridge the differences between E and F sockets. This plug, which is basically the earthed universal Continental European standard, has earthing clips on both sides to mate with the type F socket and a female contact to accept the earth pin of the type E socket. The original type F plug, which does not have this female contact, is now obsolete.

Voltage (120V or 230V), frequency (50hz or 60hz), and that neutral, phase and ground are correctly connected.
How that is accomplished doesn't matter much.
And lot of current things use universal power supplied, so they can take any combination of the voltage and frequency in common use (marked on the PSU).

On desktop computer PSUs, I meant almost any AC to DC converter.

[twin dew]

Because the plug for wall installation is usually mandated by law?
So the law would need to be changed?

[soft bloom]

this sounds like type e is better than F

but having ground is definitely better, isn't it?

(even though i'm yet to see a socket that has it, lmao)

*grid socket

fuses in plugs are lit

unless you break them too often

but at least that way you wont have half the appartment shut off because you turned on e-kettle

huh

pun intended?

couple of years ago when i returned into city, and lived with parents a bit, i had to call eletrician to check on the switch that leads into appartment. 1) beacuse it was shutting off by itself 2) because i noticed it was sparkling (well, connection to it). it was as simple as replacing one of the wires and secutring connection. but it was a messy old box full of dust and uncovered wires...

[twin dew]

Early aluminium wire usage is dangerous.
And caused significant amount of house fires over time.

That is early aluminum wiring use for houses IIRC.

Didn't know that if you used same type of connecting as with copper wiring, they would loosen over time and cause the connections to get hot.

The wiring itself wouldn't have needed replacing.
Just everything else would have needed to be redone to be aluminium wire compatible and with suitable connection methods.

Including any connections between wire segments.

Just needs suitable wire size.
Which is larger for aluminium wiring than for copper wiring.

But still cheaper.

Which is why there was try to move to aluminium wiring from copper.
Which failed because of "skill" issues.

Yes, if the breakers were changed to higher rating, the wiring needed to be redone anyways.

No matter what material.

Got bad name from those early style problematic installations.

And needs more knowledge from the installer to do it safely.

Often it is the other way today.
Use copper for the low power lines and aluminium for the high power utility sockets.

Or fixed stuff.

You're disappointed in the entire state of Germany or just the "producer" who imported the stuff from china, slapped their label on it and you fell for it?

Wat

[soft bloom]

dam
i want to backup the backup
so i made a zip of the backup
and now i want to put a password on it
but i dont remember what password i used for backup
and even not sure if it has one...
(talking about classic Deja backup app)
what to do now?

[edgy hazel]

Well I hope you'll use a password manager now

[soft bloom]

for backup? never

also because that puts you at risk of making a loop

[edgy hazel]

a loop?

[soft bloom]

when you encrypt with password that was backud up inside

[edgy hazel]

and how does that affect anything?

[soft bloom]

suppose you need that backup cause you lost originals

how are you going to retrieve the password to restore from backup?

[edgy hazel]

by not encrypting your password manager backup at all?

since y'know, it's already encrypted

[soft bloom]

so you want to make a separate backup for password manager that will be stored separately?

at a risk of forget about it because you complciated backup process

[edgy hazel]

you should backup every service separately anyways

that's just best practice

(and it also just gives you finer control)

My smartass router qos rules somehow decrease ping under load, but that means regular ping without load sucks

Bufferbloat A+ what can I say

[edgy hazel]

https://tenor.com/view/thanos-perfectlybalanced-gif-18301221

[sand saddle]

The router is just lazy and doesn't start working until a proper load is put on it

[sand saddle]

This is actual bs, wonder how I could fix this

25th percentile is better with no load, but everything beyond that gets fucked ping wise

[edgy hazel]

simple, saturate your network. Just constantly DoS someone

[jagged snow]

That could be something on your ISP side too

[sand saddle]

Maybe it's the website's problem?

[sand saddle]

Shouldn't be, this started happening after I switched the router

[jagged snow]

That's strange behavior

[edgy hazel]

[sand saddle]

If I disable qos active upload gets fucked

[sand saddle]

The problem was simply my small brain.
Instead of restarting my PC I restarted the router hoping it would fix things. But how would that help, right? So after my PC restart it's looking like this:

[edgy hazel]

it's still running

You should go catch it
