Are the small ones on the floor chonky blade servers?

clear ferry
#

Well, they are edgeline 1000s

#

Kinda blade ish

#

Not quite

#

More, edge nodes for rough environments

#

That have cartridges

#

We have the Moonshot 1500 too which fits 200 servers in 4.8u

#

Or was it 4.2

Did someone say internet backbone

rapid tendon
#

Figured out root cause, the hdd i was using was starting to fail

#

Glad i picked up a spare cuz gut feeling told me there was a chance

hollow glacier
#

cool

#

my nvme drive in my pc died last week

#

still sad about it

#

i specifically said it wasnt haos cuz if it was buggy shit we'd all be complaining daily

rapid tendon
#

got an ssd this time around instead of spinning rust

hollow glacier
#

yep

rapid tendon
#

Also explains why i couldn't find logs of the root cause when it came back up from reboot lol

#

restore process took a lot longer than the estimated 45 mins by the webui

#

2.5h

#

But, i'm back up and running 🙂

#

Interestingly, the restore process doesn't restore network config

#

does restore the DNS servers set in the network config, but not the network interface setup

#

was slightly frustrated by that but it's not that big of an issue tbh

#

i can see the value of being able to restore a backup to say a secondary system before replacing it, making sure services are running so it's a relatively seamless replacement

hollow glacier
#

and the network config used to be 1:1 after a restore

#

but that would fuck up when i wanted to restore to a test VM

#

so imo probably best that way

#

you'll need to do a full host reboot after a restore btw. also we are in #the-water-cooler this is a shitpost den

do you guys think a 90* adapter for the 12vhpwr is a good thing to buy?

solar zealot
#

eh i see its 3-4 weeks delivery time lol

#

Has anyone used the Govee Outdoor Permanent light? And if so, have you added your own custom jumpers to go from soffit to soffit? If so to Q2, have you had issues with the last few lights now working?

I only added about 25 feet total of jumper wire, and also didn't use about 8 of the LEDs, and I am having issues with the last 5-7 LEDs lighting up or even being recognized in the Govee app.

I bought a different power adapter that is still 36V, Sam as the original, but has 144W of output, double the original power adapter which is rated at 72W. I was thinking this would give it enough umph to let the whole strand, but it is dying off at the same spot.

Any suggestions of what to try next?

# hollow glacier if you want a reliable led strip setup with proper power injects you build them ...

I hear what you're saying but it's also naive to think that everyone has That's required to do that or the bandwidth to learn it. Some people (like myself) like to tinker with home assistant and not necessarily build everything from scratch. Not that I don't want to but I simply don't have enough time to learn everything about it.

So my question wasn't designed to be a debate whether you should use pre-built versus homemade strips, there's a question of if I'm missing something about why the rest of the strip isn't lighting like it should.

solar zealot
#

its kinda caused by the voltage drop over the lenght of the strip

#

you could try and see if both halfs will run properly in parallel and if so, add some injection in either the middle or the end

verbal silo
hollow glacier
solar zealot
#

its effectively trying to achieve the same, but in a slightly more flexible way

prisma briar
solar zealot
#

i kinda wonder why those strips not have that stuff in built

hollow glacier
#

Because they prey on naive people who think they’re buying a premium product at a premium price

verbal silo
hollow glacier
#

Check solder joints or clips it’s most likely just a bad connection on data wire

solar zealot
#

i mean if their product page says that will work, it should

hollow glacier
#

If he cut them to length and attached wires to jump areas with no leds there’s just most likely a bad connection

verbal silo
#

I mean, of course you are not SUPPOSED to modify them like that, but I did do some research before and saw more than a few people wrap far more length that I did around their house with them.

hollow glacier
#

I’m not suggesting you did anything wrong

verbal silo
#

I soldered the first time, but the uncontrollable nature of doing it while on a ladder outside led me to believe I just got crappy cold solder connections so I clipped them all and did crimps with the same results.

hollow glacier
#

I only use wled open source app and firmware but we have to go in and change led count. You’ve done that but leds are dead right? It’s possible you bridged power and ground and zapped one. Cut the first led off that isn’t turning on and try again

#

Usually it just zaps one led if that happens

verbal silo
#

I'll take a look at the link you sent earlier and see if that leads me anywhere before I put another cut in the strand.

hollow glacier
#

I linked power injection cuz at first glance i thought you were talking about brightness and colors at end of strip not being the same as the beginning

#

got a general ssh question someone might be able to answer - I have Server A which can locally connect to Server B. I'd like to access server B via SSH but through an open port that's open on Server A, but already has sshd running. I think the solve would be an SSH tunnel if I understand them correctly

#

does that sound right?

solar zealot
#

yesish

#

the tunnel would be from you to A so you can connect to B

#

pretty much like a proxy

smoky birch
#

well, that's kind of how I'm operating rn - I can SSH into Server A because there's an open port, and that machine can SSH into B. Ideally though I'd like to SSH directly to B through a tunnel I think. Trying to SSH git pull a repo on Server B

#

B doesn't have a port forward

#

It's only accessible on the LAN but it's a different port

solar zealot
#

another option would probably be to forward all traffic from some port on A to ssh on B

#

but that may be a mess to configure

smoky birch
#

yeah... my goal is to not need another open port... I think if I configure the tunnel to bind to the open SSH port on A, it should work because the user managing git doesn't exist on A, so I think it would try B?

solar zealot
#

no

#

you cant really have two things on one port and have it figure itself out that easily

smoky birch
#

so I'd need to kill sshd on server A

solar zealot
#

that would kinda kill ssh access and the tunnel

smoky birch
#

yeah

solar zealot
#

you may just setup a dedicated ssh profile which will ssh into A and then ssh into B over A

#

or the tunnel solution

#

or forwarding via iptables

#

i dont think there are more viable options

smoky birch
#

i think I got something... on my localhost:
ssh -L localport:serverB:serverBSSHPort serverAUser@serverA -p serverAPort

#

telnet localhost 1234:

SSH-2.0-OpenSSH_9.2p1 Debian-2+deb12u1
solar zealot
#

yes thats pretty much how a tunnel works

#

but dont use telnet

smoky birch
#

telnet was just to demonstrate that it's pointing to the correctp lace

solar zealot
#

i see

smoky birch
#

didn't clarify that debian one is Server B

#

and yeah ssh localhost -p localport is gucci

#

localport is 1234

#

appreciate your help 👍

#

heh, new problem - git cloning a repo from localhost:1234 prompts for a password

#

i think i'm missing the ssh key

#

Sort of off topic, but I got notified by my router today of a suspicious connection to my home assistant, at the time my DNS service was completely stopped so I don't anticipate any connection outside my local network. Any thoughts? The conspiracist inside me says Netgear is making these up so I eventually pay for their security services

It's probably just a bot

If it's a datacenter it's either a bot or someone doing something nefarious

primal laurel
#

They're trying to poke holes

smoky birch
#

Had someone hitting me from an Amazon AWS datacenter from multiple IPs

#

Reported to Amazon and never saw it happen again

#

I guess I assume they were doing nefarious - they were hitting my authentication page with incorrect password attempts

#

HA was sending me notifs

west trout
#

Any suggestions for increasing the security?

#

I could VPN my home assistant I guess

smoky birch
#

if you're not already, fail2ban on home assistant host

west trout
#

I'll look into it, thank you

smoky birch
#

only open absolutely necessary ports

#

reverse proxy is a good way to keep things local

#

er, map local things to outward facing things without exposing too much

primal laurel
#

I'm always on a vpn but I also have nabucasa

smoky birch
#

does netgear tell you anything specific about the connection, like the port trying to be accessed? @west trout

west trout
#

Not on the app, let me check on computer

#

Probably a log somewhere

smoky birch
#

yeah

west trout
#

While looking for the log, I read that Netgear has a lot of false positives

#

For their security attack detection

#

Damn log already wrote over itself

smoky birch
#

did HA notify you of anything?

in the UI

#

No

I hope I am using the correct channel for my message, apologies in advance if I don't.
I am looking for a developer who can help me build a custom integration for home assistant that integrates with an ip gateway by sending a set of hex commands over udp to steer a gateway.
Pls message me here if you are interested or if you have any advice on whom to reach out to.

The 48kw plug yes

clear ferry
#

Which equates to about €25 per month

#

And yes, most modern norwegian houses have 3phase power

#

My house only has 3phase 230v, but post 90s do 3phase 400v

solar zealot
#

I think this would cost around 6 bucks a day here

clear ferry
#

Oh, my math was wrong, it will cost me €2.5 per day

#

With current prices

#

with <2020 prices it would have been €0.5 per day

#

So roughly the cost of a netflix 4k subsciption today

#

which I have cancelled

glacial knot
clear ferry
#

No

#

The distribution is 230 or 400

#

Then from the house breaker we then do either L1+N+PE \ L2+N+PE \ L3+N+PE if it is 400v in, and different portions of the house uses different phases, but if it is 230v distribution it would be L1+L2+PE \ L1+L3+PE \ L2+L3+PE

#

If memory serves right

#

So my house as 230v in, so I'm limited to 7.4kW EV charging, but if I had 400v I could do 22kW

primal laurel
#

you mean 7.4kW single phase?

#

You would only get 400V if you connected your load between two phases. Single phase to neutral would get you 230V

clear ferry
#

Yes

#

House is 230 3ph in

#

and all is 1ph from there

#

Modern houses is 400v 3ph in

#

so you can do both 1ph and 3ph from there

finite atlas

just do 3x 7.4kW charging

No 23V. From 253V to 207V

It's to account in variances between regions/locations, not day to day variances for one spot

#

Yes

clear ferry
prisma briar
#

idk about Europe but in the US apartments frequently use a lower voltage for two phase, too, 208v vs the 240v in homes.

primal laurel
prisma briar
#

It's also a factor of how far you are from a substation

#

If you're seeing a full 10% swing from day to day in one spot there's probably a problem somewhere

finite atlas
primal laurel
#

It's pretty normal here, due to the large amount of solar panels

#

I am even hitting 253V on very sunny days and then the inverter shuts off

prisma briar
#

Not sure what the gap with no data is from but voltage here is generally rather stable

#

And that range is only that wide because that sensor has a fishtank heater on it that turns on/off frequently

It does not very much at our house as well, located in germany.

from last summer

#

this is what massive solar does to the grid

#

huge amount of power available, nobody to use it. Power becomes worthless

prisma briar
#

Sounds like a good thing tbh

primal laurel
#

it can be very profitable for those on dynamic contracts. I expect prices to go towards minus 1 euro/kWh on some hours in the summer

prisma briar
#

There's some solar around me, mostly gas power stations though

primal laurel
#

I counted the roofs here once, it's about 50/50 solar vs no solar

#

probably higher now

prisma briar
#

Not many homes have solar here but there's a few fields where they laid out solar around

#

Basically no wind power where I am, too mountainous

primal laurel
#

Solar is great. Very cheap, lasts a long time

#

Our government made it so profitable its basically a no brainer

#

Cost recovered in 3 years or less if you do well

prisma briar
#

There's solar rebates here but I'd have to convince the city to cut nearby trees down or my roof is in the shade most of the day

#

And I don't really want to lose those trees or think they would cut them down anyways

primal laurel
#

It depends. Usually cutting some branches is enough

#

I have also seen that in the cold season you suffer much less from shade from trees because the leaves fall, but obviously you also have less sun

#

In the summer the sun is much higher in the sky, so in general you suffer less from shade

#

But I have modelling tools to check that for me haha

NOTE: ...

subtle pasture
#

My outlets read 123v on average, with a maximum variance of +/- 2 volts.

prisma briar
#

114 seems high for a UPS to kick in at

subtle pasture
#

114v is when it starts regulating voltage back up to a stable level (transformer running). 106v is when it trips completely to battery power.

#

APC default for Smart-UPS units

clear ferry
#

I'll probably buy solar when I buy a new house

subtle pasture
# prisma briar

The voltage in this graph would basically leave the transformer and fan humming all day, which technically also shortens the lifespan of the unit.

prisma briar
#

Sounds like a bad UPS configuration

subtle pasture
#

That's how all line interactive APC UPSs operate...

#

They'll also start running the transformer if line voltage is too high, and trip to battery if line voltage becomes excessive.

prisma briar
#

If your stuff is destroying/aging itself because it's at 114v instead of 120v it's a crappy unit

clear ferry
#

Mmmm line active

#

Love that shit

subtle pasture
#

And it's better for it to run the transformer than it is for it to run from batteries, because batteries age a hell of a lot faster than the other compontents in the UPS

prisma briar
#

Sounds like a waste for just powering home computers

#

Modern PSUs are happy down to like 85V

subtle pasture
#

I mean, no waste here. My line voltage is usually well within the butter zone, so the UPSs sit idle all day

subtle pasture
prisma briar
#

I think mine trigger brownout protection at 90v

subtle pasture
#

It's usually adjustable within a range

prisma briar
#

But a modern computer PSU will run happily on a constant 85v

subtle pasture
#

Usually the issue we have here is line voltage being too high. I have a client right next to a substation, and the transformer in the UPS in their server rack runs almost constantly because the line voltage likes to hover between 126 and 130v.

#

Poor UPS is regulating down to 120v all day long

subtle pasture
#

And I'd fully expect a UPS to compensate for that

prisma briar
#

Yea, the UPS should be on well before 85v, but 114v seems high

subtle pasture
#

Transfer voltage is 120v +/- 5% by default on APC UPSs

#

114v would be pretty low voltage for the grid in my area.

#

You could reconfigure a UPS to deal with that, but it's not gonna be happy out of the box. lol

subtle pasture
#

Anything is possible when you don't label the axis on your graph...

prisma briar
#

Also when you're not afraid to make a GPU take a kilowatt

subtle pasture
#

Eh, Nvidia has some sanity in that department. The RTX 4090 is perfectly capable of drawing 1kW, but the performance gain of a few percentage points over 450w isn't worth it, so they capped it.

dusky plank
#

a kilowatt seems about right

Bildschirmfoto_2023-11-13_um_17.44.39.png
subtle pasture
#

Granted, they could have capped it significantly lower than 450w and still retained 90% of the performance.

prisma briar
#

The 4090 is capped at 600w out of the box

#

As long as you have the right power connector

#

If you only have a 3x 8 pin adapter it'll cap at 450w

subtle pasture
#

Then TechPowerUp has the specs wrong for the 4090

#

They list it as 450w for the founders edition

prisma briar
#

By capped I meant what you can configure it to take, not it's default limit

#

But it's just a power draw slider

subtle pasture
#

But as discussed, there's literally almost no point in adjusting that slider.

#

Even flashing it with a 1kW BIOS doesn't net you more than a couple percentage points

prisma briar
#

I got about a 11% boost in performance between 300w and 600w

#

So I run it at 300w

subtle pasture
#

You also start to get paradoxical effects where lower power targets perform better if your cooling can't keep up

prisma briar
#

There's 5lbs of copper and fans on my 4090, it better keep itself cool

#

That is in no way an exaggeration either

subtle pasture
#

I already get inverse scaling on a 3080. lol

#

I run my power target at 96% because it actually performs better that way

prisma briar
#

I couldn't get my 4090 to thermal throttle, it always started complaining of an unstable power supply at around 580w draw and refused to go higher

#

It gets really loud though

subtle pasture
#

It's not that it was thermal throttling, it's that it would run slightly warmer with the higher power target, so it'd drop a boost bin or two at the worst possible moments.

#

Reducing the power target led to better 1% lows. Go figure 🤷‍♀️

primal laurel
#

I upgrade my gaming PC every 4 years or so. Next gen the main differentiator is going to be perf/W for me lol

prisma briar
#

I'm not spending this much on a GPU again, that's for sure

#

Only got it for VR anyways and game devs seem to have given up on VR

subtle pasture
#

I bought my 3080 in the middle of the GPU shortage for $999

#

Also for VR, because a 2070 wasn't cutting it.

dusky plank
#

my GT 710 was 10$

#

I don't game

prisma briar
#

I sold an RX 5700x for $700 and got a 3070 during the shortage for $850, later sold the 3070 for $300 and got a 3090ti, found nvidia screwed up displayport on the 3090ti and it wasn't going to work reliably with my headset and got a 4090 instead.

subtle pasture
#

Though at least I also have triple monitor to use the 3080's horsepower with. Driving 5760x1200 is pretty demanding in its own right.

prisma briar
#

My VR headset screens are 7680x2160

subtle pasture
#

I had 3x DisplayPort monitors + 1x DisplayPort headset connected to my 2070 no problem.

#

Want to do that with a 30 or 40 series? Gotta go Quadro.

prisma briar
#

Or get an mst hub

subtle pasture
#

Doesn't work, tried several

#

The Valve Index absolutely refuses to work with an MST hub, as does Nvidia Surround / G-Sync

prisma briar
#

I have gsync through one

subtle pasture
#

I could technically get output from all three monitors using an MST hub, but they wouldn't create a display group.

prisma briar
#

Never tried surround, and yea, an index won't work

subtle pasture
#

The Nvidia Control Panel just wouldn't see the monitors connected to the MST hub as avaiable for Nvidia Surround, at all

prisma briar
#

I have a USB/Displayport KVM switch that acts as a MST hub too that's been solid for me

#

Weird

subtle pasture
#

Apparently it's expected. Nvidia doesn't certify Surround to work through any kind of hub or daisy chain.

prisma briar
#

There's HDMI to Displayport adapters too

So you can't even sacrifice a monitor to plug in the Index in a semi-automated fashion, gotta physically swap cables.

I don't need a repeater, I just need my card to have a 4th DisplayPort output likethe 20 series did <_<

Isn‘t usb-c -> DP a thing?

USB-C can do alt dp mode and carry displayport but it needs to be fed from a displayport source.

subtle pasture
#

Only certain USB-C ports support DisplayPort output. The RTX 20 series had one such USB-C port onboard, which is where the 4th native DisplayPort output comes from.

prisma briar
#

You can get USB-C cards with a Displayport in that'll give you USB + Displayport out over a USB-C cable

subtle pasture

Yeah, but you have to connect a DisplayPort output from your graphics card into the USB-C card for that functionality to work

#

They'll have a DP-in port for that

Yup.

My motherboard has two USB-C ports with DisplayPort support, but they connect to Intel Integrated Graphics, which is useless for my purposes

With a latency hit, and good luck getting VR, Surround, or G-Sync working like that...

I guarantee you I can't make a Nvidia Surround group with a display connected to Intel Integrated Graphics

the talk was about the 4th output

Right, a 4th native Displayport output on the primary GPU is required here

Otherwise you run into issues with simultaneous support for a VR headset AND a triple-monitor setup with Surround and G-Sync

Get an ultrawide and reduce your screen count

subtle pasture
#

Most solutions for connecting three DisplayPort devices to an RTX 30 or 40 series card result in something breaking

#

Or Nvidia could stop nerfing thair consumer products. Remember when you could run 5 displays off one card? GTX 1080 was their last consumer card to support that. Limit is 4 now...

#

And 4x DP outputs wasn't a problem for the 20 series. Could have been included on the 30 and 40 series, but they decided to restrict it to workstation cards.

I'm fairly certain every consumer nvidia card has been limited to a max of 4 displays

I had two 900 series cards, they were hard limited to four monitors per card.

#

I had nvidia optimus working between that and an igpu so the igpu output was rendering on my 970, even then it would only activate four displays. I tricked it to get around it by making the last display my final monitor + the monitor I was putting on my igpu and making the framebuffer that got copied to the igpu start half way through the final monitor

#

I know AMD supported 6 Displays since the HD6000 series
Which is somewhere around GTX 600 iirc. And AMD was slightly earlier on consumer cards

prisma briar

So it thought that my final monitor and the monitor on my igpu were clones but the 'clone' was offset

my first Nvidia Surround setup was two GTX 260's in SLI

Huh, that's a very interesting thing
Because that's more Crtcs then
The panning isn't done by the card.
Should have been possible to use independent entirely
Though maybe not exposed properly by some older config

I think that thing was intended for video walls, though

The first four screens would pan, the fifth offset clone one was always locked where it should be

When Nvidia dropped SLI support, multi-card spanning went out the window. Only Quadro/workstation cards can do it now.

I used a hacked nvidia driver to SLI two different 970s around 2018, I wonder if anything like that could still be done

subtle pasture
#

I've done the "dGPU outputs through the iGPU" thing before, and there's always noticable latency

#

Which would lead to the 3rd monitor being de-synced from the first two

prisma briar
#

Are you actually gaming on all three at once?

#

If not it's not really a concern

subtle pasture
#

Yeah, Nvidia Surround merges the monitors into one giant monitor in hardware.

#

OS sees one giant ultrawide

prisma briar
#

I know what Surround does

glacial knot
#

Though the latency would be a bit higher

subtle pasture
#

I still don't want one monitor a frame or more behind the others. My HD 6970 did that in Eyefinity, and it suuuuucked

glacial knot
#

If you want actual synced scan out, there's some proprietary Intel tech though

subtle pasture
#

If you used mismatched outputs on the HD 6000 series (like 2x DP and 1x HDMI) the HDMI monitor would be a frame behind and/or experience constant tearing even with V-Sync enabled. It made turning feel "wobbly"

glacial knot
#

They use it to drive 8k Displays
Because they didn't fit the pipe of a single scanout engine

prisma briar
#

There's a program for VFIO to stream a display from a gpu assigned to a VM to a GPU on the host through a shared memory block that from what I've heard is <1 frame latency, idk why the OS wouldn't be able to equal that.

subtle pasture
#

I've also used software-based triple monitor, and the latency on monitors that aren't on the primary card was awful

glacial knot
subtle pasture
#

SoftTH actually works pretty well when you can connect all monitors to one card, though

prisma briar
subtle pasture
glacial knot
#

Scanout on a different GPU necessarily has to transfer the framebuffer

Vfio allows to transfer a handle instead

prisma briar
#

For looking glass it renders on the guest gpu then reads it back into system memory to be rendered on the host gpu

🤷 back in the day my displays were heterogeneous enough for it to not matter

Thankfully haven't had that issue with any of my DisplayPort monitors, though I have had that issue with various DisplayuPort-to-HDMI adapters

Having to disconnect and reconnect the one monitor on an adapter got old real fast

Yea, passive/active
And active without external power can be super iffy

It was an active DisplayPort to Dual-Link DVI adapter with external power that was the most flaky actually...

Anything advertising above 1080p@60 active without extra power is either straight lying or unstable

I had one of those
Earlier days of DP, and hardware was just generally worse

#

One of the cooler things that DisplayPort supports, that nobody uses, is software defined display coordinates.
DisplayPort spec allows you to carve up an attached display into any number of sub-displays, but literally nothing supports it.

#

I'll even see 4k monitors and ultrawides that support splitting the screen into quadrants, or in-half, but they do it using multiple cables rather than the built-in features of DisplayPort

glacial knot
#

Pretty sure the ones that do it in one cable do it via MST

subtle pasture
#

MST is its own thing, seperate from software defined displays

glacial knot
#

Do you have a link for that?

Never heard of it, and a quick text search for "software" in the DP wiki article shows nothing

MST basically is software defined displays

MST is basically two cables routed through one

subtle pasture
# glacial knot Do you have a link for that?

I'm not sure it's an explicit feature. My understanding was it was inherent to the technology, and how display surfaces can be arbitrarily defined from the available total screen area.

subtle pasture
#

I've not seen a monitor that uses MST to turn itself into 2 monitors, though I have seen monitors with two inputs that can simulate being two monitors.

Why would one monitor use MST to turn itself into two?

#

Window management often works better that way

glacial knot
#

Usually exists because it's 2 panels either way
Either to support older standards via 2 inputs, or just weird tech

prisma briar
#

There are so many better solutions for window management than making your monitor appear as two screens using MST

subtle pasture
#

Being able to switch between "two 16:9 displays" mode, and "one 32:9 display" mode, is handy

glacial knot
#

🤷

#

Not every feature is useful

subtle pasture
#

When I get an ultrawide in here, I'll absolutely be connecting it twice so I have the option of making it simulate dual monitor

prisma briar
#

I get the point of using two cables to an ultrawide and using surround, one cable is limited by bandwidth and starts using DSC

#

At least at 144Hz+ refresh rates

#

But one cable to an ultrawide using MST sounds like the worst of both worlds, lol

subtle pasture
#

In the example of splitting up an ultrawide, bandwidth limitations aren't a concern. The cable is either carrying one 3840x1080 stream, or two 1920x1080 streams. Basically the same bandwidth either way.

#

The difference is the OS sees one monitor or two, and I didn't need to run two cables

#

But I have yet to see a monitor that can do that using MST. They all require 2 cables 🤷‍♀️

prisma briar
#

There's ultrawides out there like the 5120x2160 ones that exceed a single DP cable's bandwidth so a second cable is the only way to get an uncompressed image on them

#

3840x1080 will fit on one cable

subtle pasture
#

Latest DP spec handles those resolutions fine now

glacial knot
#

Unless you run a very specific config, they will tear between the two images though

#

It's a dumb solutions to run

prisma briar
subtle pasture
#

Being able to spoof that you have two display devices comes in handy

glacial knot
prisma briar

I couldn't even get nvidia surround to activate on my ultrawide when I tried, whenever I activated it it got the resolution wrong and nothing I did would get it to go to the right resolution

subtle pasture
#

Well yeah, LinusTechTips did a video about an old monitor that worked like that

#

And it did have tearing

prisma briar
#

I can't imagine gsync would work like that either

subtle pasture
#

I think it was a really early 4k monitor that required multiple inputs + a computer that supported spanning, and they couldn't fix the tearing at the seam.

subtle pasture

That was the monitor they tested with that like 500ft thunderbolt cable I think

Three ultrawides spanned is kinda unusable

glacial knot

Yea. I know that Intel has tech to avoid that
But 🤣 Intel GPUs and use cases that care

But the entire point of wanting to emulate multiple smaller displays with one large one is to not span things

If I wanted to span things, I'd leave it as one large display. lol

KDE can do that

And it gets its own resolution, color depth, and refresh rate

#

I'm not sure KDE can do all that...

glacial knot
#

Neither can any hardware

prisma briar
#

The refresh rate and color depth are up to your hardware, all the software is going to do is define a custom region for a monitor

#

But you can use it for things like getting multiple task bars on one monitor/making windows maximize to only half the screen

subtle pasture
#

It was limited to changing display modes at every scanline, so you were limited to multiple horizontal monitors per-monitor, but it was still pretty damn cool

prisma briar
#

Sounds 50x more useless on an Amiga

subtle pasture
#

Nah, it was really useful when you had older applications that needed low-res screen modes on an Amiga running a hires desktop

#

You could pull a 640x480 monitor over a 1280x960 monitor seamlessly

#

No mode switching, it was just changing right at the scanline between the two modes

prisma briar
#

With features like that how did they ever lose

subtle pasture
#

If you had a PC card installed, you could even pull DOS (or if you had a fast enough one, the Windows desktop) down (running at its own resolution, refresh rate, and color depth) over your Amiga workbench

prisma briar
#

I imagine that wouldn't work at all on any monitor that actively monitored the sync

subtle pasture
#

And it was all happening in hardware, not with windows or a window manager

prisma briar

That could only ever work on really dumb CRTs

The screen geometry would be way off though

subtle pasture

I'm fairly sure it was still just RGBHV

True enough, it's similar enough to VGA that it'll work on VGA monitors that A) support slow scanrates,and B) support sync-on-green

prisma briar
#

Oh, it's RGsB

glacial knot
subtle pasture
#

It supports changing things mid-scanline, so...

prisma briar
#

Changing resolution half way through a frame like that would surely cause weird problems like the screen bouncing though

subtle pasture
prisma briar
#

Looks like it's only changing the horizontal resolution to me

#

Which is a lot simpler than actually changing the full mode half-way through

#

Probably just pixel doubling though

subtle pasture
#

Both the horizontal and vertical resolutions are altered

glacial knot
subtle pasture
#

Commodore referred to this tech as "ViewPort" if you want to look into it

glacial knot
#

not really. It's not super interesting. Unless you have a direct link supporting your claim that it did something that shouldn't be possible, I'll assume you are wrong

prisma briar
#

I see nothing about this that indicates it's changing the mode being output to the screen in one frame

#

Seems more likely it's using pixel doubling, all the resolutions are multiples of the step below

subtle pasture
#

Pixel doubling wasnt a thing on the Amiga, it would just run a lower resolution...

#

There was literally no need to pixel double a resolution on an analog CRT

prisma briar
#

What you're describing isn't a thing.

prisma briar
#

At the best that'd give you a really shaky image

clever mortar
#

BBC B did something similar from memory

#

Flipped the mode part way through - Elite did that

subtle pasture
#

Then how do you get images like this, with 320x256 progressive-scan on top and a 640x512 interlaced on bottom?

gNrlW.png
prisma briar
#

You may be able to increase the horizontal sample rate but that's all you'd be able to change

prisma briar
subtle pasture
#

Commodore has always described this as the mode being changed at the scanline at the boundary between the two screens

prisma briar
#

Each display mode specifies (among other things) a pixel resolution and a monitor scan rate. Though the Amiga has the unique ability to change pixel resolutions on the fly, it is not possible to change the speed of a monitor beam in mid-frame.
Therefore, if you set up a display of two or more ViewPorts in different display modes requiring different scan rates, at least one of the ViewPorts will be displayed with the wrong scan rate.

subtle pasture
#

Also, if it were always running a higher res and pixel doubling, a lot of software would balk due to a lack of memory. The lower resolution screen modes were required to access higher color depths.

glacial knot
#

You modeset to whatever looks closest as superset and do some client side processing

glacial knot
prisma briar
glacial knot
#

emulating that isn't super hard
Actually doing that over the wire is an entirely different thing

prisma briar
glacial knot
#

you can easily emulate that on modern hardware with quite a bit more freedom via planes
But you still modset the display to a single specific mode.

prisma briar

You absolutely cannot change your vertical sample rate half-way through displaying a frame/field.

The screen would lose tracking and start bouncing up and down

In VMWare terms.
Enabling "Fault Tolerance" on a VM or container means it'll survive anything as long as one FT-compliant host remains running. The VM or container is run, in lockstep, on at least two physical hosts at all times. You could walk up to the rack and yank a blade out, and the VM or container would keep running like nothing had happened.
Enabling "High Avaiability" just means the VM or container will automatically restart on another host if the original host dies. There will still be service interruption.

They repeat this song and dance every few minutes.

#

do you use the zigbee integration in HA?

subtle pasture
#

Unplug the Hue hub, they all stop blinking and stay connected to Home Assistant no problem

prisma briar
#

I use ZHA, yea. My thermostat didn't work with Z2M.

subtle pasture
#

Yeah, using ZHA

#

I'm a little perturbed that a un-associated Hue hub can still screw with my bulbs, though. I'm assuming the hub sends out some kind of magic packet that their bulbs listen for, even when paired to some other Zigbee coordinator/router

prisma briar
#

I think they use bluetooth to scan for nearby bulbs

subtle pasture
#

They're waaay too far away from the hub for Bluetooth to reach

dusky plank
#

do you know how far btle reaches?

Hue doe ssome non-standard stuff

Also, some of these hue bulbs are so old they don't have bluetooth

dusky plank

It seems like the Hue hub is broadcasting something that kicks Hue bulbs into pairing mode, regardless of their current connection.

#

better answer me how to get browser NOT turn to google if I give them non-standard TLDs (my domains)

prefix http://

dusky plank

whout that ^^ and without ports ^^ and without ending slash

all of these suck on mobile

prisma briar
dusky plank
#

exactly

glacial knot
#

onsome browsers you can press the down arrow, and the suggestion box will have an entry with the magnyfing class for search and one with the globe to browse to the woname

subtle pasture
#

The Hue dimmer remote can also kick bulbs into pairing mode, no matter what they're already connected to (hold the I and O buttons on the remote, at the same time, near a bulb. It'll start blinking)

#

So they've got some special thing the bulbs listen for...

glacial knot
#

what device and browser do you use? It just works™ for me

prisma briar
#

The first comment seems to imply all you need is the trailing / and not the full http://

glacial knot
#

oh wait no. I have a normal TLD

dusky plank
#

yes adding "/" solves that, still sucks

#

I have normal TLDs too, but I don't want to google my internal ones

glacial knot
#

I know some browser (probably firefox) has an option to set the mode
And either use a rough metric, or fall back to DNS and connect if it resolves, otherwise search

    Manage search engines...
    Add a new search engine and use these as the 3 values:

    c. http://%s/
    Make default
glacial knot
#

LoL just use https

prisma briar
#

Just make a custom search engine for your hostname that redirects to your hostname. :P

dusky plank
#

I have to test that

subtle pasture
prisma briar
#

It won't do the tld but it'd do a host

dusky plank
#

but then I can't google sentences anymore in the url bar

#

life sucks

#

I get it

subtle pasture
#

The web interface for Tasmota is one that's real annoying to get to if your browser keeps trying to swap to HTTPS

prisma briar
#

You can make it so entering a word in the search bar triggers it as a custom search engine, though now that I think about it you have to hit space afterwards anyways

dusky plank
#

thank you @prisma briar though for that workaround which breaks other stuff

prisma briar

I have some set up at work, I can do 'ip <ip>' to look up an IP address in our IPMI

I have one to look up customers too

how?

#

thats why you have 4 monitors right?

subtle pasture

3 monitors, and no...

#

I've been using Firefox since like 2005. It always had both bars enabled, by default, until recently.

#

Just kept with it 🤷‍♀️

prisma briar
# dusky plank how?

If I type "google " in my address bar (including the space) it turns into the second photo and then takes me to the third when I hit enter

subtle pasture
#

It's real annoying to type a search into the combination address/search bar and the browser randomly decides to open a bookmark or history item instead of searching.

glacial knot
#

yea, omnibox can be rather surprising

subtle pasture
#

So I keep the search box enabled so I can explicitly tell it to search

prisma briar
#

And I have basically the same thing set up going to a PHP page I have at work that fills out a post form on our ipmi tool to do a search for an IP

Had a 3D print fail, lol

#

a 5 year old belt on the printer snapped and the x axis got stuck in place

#

It was clearly trying to escape

#

It tried taking the silicone insulation from the hotend with it, had to cut the stick of filament from the top to free it

primal laurel
static schooner
#

It printed a mobile body and made a break for it

prisma briar
#

I put a 4 color mixing hotend on my ender 3 and was doing a test print with it, first few layers went down fine but I woke up to that.

#

It was supposed to be a few multicolor rainbows

subtle pasture
#

The location of the switch is known from the homing process, so if it doesn't trigger when the stepper is at the expected location, there's a problem of some kind

#

It's usually used to stop a print if there are skipped steps, but a snapped belt would get detected too. lol

prisma briar
#

This was the first time I've had a belt fail after probably thousands of prints

subtle pasture
#

Yeah, like I said, it's usually used as a way to stop a print if an axis skips steps

#

Handy to have enabled for long overnight prints so you don't come back to a giant pile of spaghetti or a massive layer shift

well, don't need help but ..something I never saw before ...and I find it a little weird

context: I have a ZigBee switch named "Fan" which, well, runs a fan. At the end of the season, I store the fan and unplug the plug. Since it generates something on logs all the time, I delete the switch from Z2M completely.
However, I don't want to re-do automations every season, so I just disable the parts of the automations that contain that switch, instead of deleting them.

Since couple of days, it felt weird, and I investigated what's going on with my HA. Apparently this disabled section was making the every relevant automation to "fail to setup"

#

so enabled:false doesn't work like commenting out a section

#

I work in DevOps so i value stability more these days

ashen magnet

I'm kind of invested in this setup now. I wrote bootstrap scripts for yadm so I install it and run one script and nearly everything is right.

#

I put the stuff that has to be stable in vms on the proxmox cluster

Haha I get it, I had soooo many custom scripts and hooks for pacman on arch

#

Took a while to migrate to Fedora, ngl

I love yadm. It's made things so simple.

can you define devops?

#

are you the guy that makes the software go brr, or are you the guy that makes the software go brr on the distributed infrastructure or are you maintaining the distributed infrastructure?

boreal cave

I use ansible, lots of people find it clumbersome, but I work with it all day with terraform so I’m used to it for deployments

I still quite enjoy tinkering. I'm semi retired (doing some IT work for the company I founded, upgrading from the podunk setup I was using from the original 4 guys up something more appropriate for the 70+ employees we have now). I hired a guy with the right credentials and use a few hourly people to fill the gaps and try to keep my work hours down to 20 a week (usually fail) but I do ahve time for tinkering.

boreal cave
#

My dev env actually lives inside esxi lol

ashen magnet
#

I hate vcenter so much....

#

I got tricked into using that on our few dell servers

#

it's such a pain in the butt to do anything with it because we don't have a massive san backending the whole thing and all the high availability stuff in pla

#

we ended up going proxmox at our two satellite offices just because the experience was so much nicer int he context of running vms for stuff like domain controllers and other non intensive things.

#

head office has esxi and vcenter and I am counting down the days until I can rip it out.

boreal cave
#

When I was a sysadmin taking care of it, I scripted everything in powercli so everything gets pulled to a backup server, then into backblaze

ashen magnet
#

we ended up using datto for backup

boreal cave
#

I think I go 5-6 months before manually checking up on it

#

It’s either total neglect or I trust it 🤔

#

But of both

#

Bit

ashen magnet
#

my problem was more upgrading vcenter and esxi is a bit of a nightmare via their systems that take forever and their virtual tpm stuff, while seemingly very secure, contemplates having a control cluster to handle it for the main cluster when my total server infrastructure across 3 offices is smaller than the envisioned control cluster, lol

Can you help me? I'm looking at a few TRVs/radiator thermostats to use with Home Assistant. I'd prefer them not to be too big, since one of them is right next to a door opening. I've looked at Tado, which looks great, but you have to pay 200 DKK a year for some features. I wonder if I could create a flow in Home Assistant that would do the same thing without paying. Otherwise, there's Aqara, which also looks great, but I'm not sure if I'm missing out on any functionality. It's also cheaper.

They give us a discount for proving we're competent enough to not be filing stupid tickets

No, it doesn't. There's no regulations in any country about the level of support provided between two private companies on multi-million dollar contracts.

This isn't a humanitarian or rights or discrimination issue

I have no idea why you think that would be illegal or regulated. Calling it discrimination is absurd, too.

And if all you can say to explain it is 'well you must not live in the EU' I'm going to assume you're talking out of your ass.

Microsoft very much does charge based on classifications that depend on a number of certifications in a company

It's a standard step of review when entering into a contract with another company to review how much the deal is going to cost you and adjust the deal accordingly.

My issue with that one vendor is that they require yearly renewal
