Radio Snack used to offer a portable word processor that used strange floppies that looked just like ordinary 3.5" ones, but were smaller, like 2.8". I always wanted to get some and leave them lying around to confuse people and tell them "oh yeah, they shrunk in the wash."
ocean sigil
You want “vintage” this is an HP2100 circa 1979. Note the toggle switches. That is how you entered the boot loader.
Note the paper tape reader above the monitor. The bootloader could enable the paper tape reader and that could enable the mag tape reader. Far left
16k core memory in that one!!
late fulcrum
Reminds me of a PDP-11/05 I used to use. It was fancy, however, after toggling in a very basic (3 instruction) boot loader, it could boot from its 8" floppy drive! It also used core memory, so when you turned it on, it simply picked up where it had left off, you didn't have to boot it again.
ocean sigil
This was a bit more primitive -- 13 instructions for the bootlader -- then a couple of feet of paper tape to get to the mag tape. No floppies at this time. The core memory was great though as you mentioned. As long as you kept it powered it was quick to get going again!
This unit was on a research ship - whenever the ships crane started up, the power voltage would sag and the system would crash. It would survive if it was "halted". We tought the crane operator to push the "HALT" button any time the crane was to be used if no one was in the "computer room". Saved a lot of lost data!
I think I mis-spoke - this may have been 1976
By 1979 I think we moved to DEC LSI-11's with 8" floppies

frail forge

jaunty jetty
then you got a better bin, sweet
CPUs are too complicated and precise to reliably create at peak quality, so they bin out what gets made based on how good it is, since your CPU is running the same parameters at 500mV less, A, it's consuming less watts per performance, and B, you could overclock it further
(note that there's about 50 bajillion ways in which this isn't true, the first one being that they're not running at the same parameters and your current CPU is just configured to run at a lower performance for the sake of thermals and power consuption)
(the second being that CPUs don't tend to run at constant parameters anymore, and you're not comparing apples to apples)

hmmm, speaking of CPUs
One of the major differences between the M0 and M4 lines is that M4s have predictive execution and M0s don't; so does that mean that M4s are potentially succeptible to Meltdown/Spectre?
yea the M0 has a 3 stage pipeline, and the M4 has a 3 stage pipeline with 'branch speculation'
(M7 has a 6 stage superscalar pipeline with branch prediction, which I guess is better than speculation)
jaunty jetty
nah, I have an M3
the M3 does not have prediction or speculation
huh, I guess that's why the M1, M2 and M3 never got popular
late fulcrum
Meltdown/spectre depend on predictive cache filling, and I don't think the M4 has a cache.
jaunty jetty
that appears correct, so good
the M7 has instruction and data caches, so maybe it is succeptible
(M1 and M2 don't exist)

someday the space aliens will make an entropy-increasing machine to hurry the end of things
jaunty jetty
that sounds more like a human thing to do
it'll probably be how we invent warp drives, but it'll take a thousand years for us to realize that they're hastening the end of usable existence, somebody write this book
wasn't there a story in TNG where there was a region of space where warpdrives didn't work because too much warping had been done there for too long so the subspace was all busted
dusty citrus
We're not going to get there. ;)
warp drive is just a sci fi trope; not related to reality at all.
jaunty jetty
I'm using it as a standin for some kind of pFTL process, but except for the subspace stuff that they kinda wrote out, warp travel is a viable premise

can't cherry-pick which fantasies had enough elements in them to have later correlated to something we did in fact, to (such as icarus).
jaunty jetty
the physics we know say this would work, making it happen is a different conversation
dusty citrus
Anything near light speed has the cow-catcher problem.
How are you going to avoid running into obstacles?
jaunty jetty
warp travel doesn't rely on high relativistic velocity
dusty citrus
(including helium atoms, which are radiation to you, at those kinds of velocities)
jaunty jetty
you shrink the space in front of you, expand the space behind you, and stay perfectly still as the space you're in travels at an arbitrary velocity, you don't have the cow-catcher problem because there's no net velocity
dusty citrus
hehe.
jaunty jetty
if you 'run into a thing' it enters the warp field and has no relative velocity added
dusty citrus
also there's the small matter of tracking your location when the basic geometry of spacetime from your point of view moves things outside your reach to places you cannot specify.
jaunty jetty
if it was travelling with a high relative velocity to your velocity then it will continue to move in the moving reference frame as if it were outside the reference frame
dusty citrus
If there are any experiments done (there won't be) those folks aren't coming back to report on it (at all).
I'm really not worried about this. I saw it come from nothing into its present form.
There was almost none of this when I was very young. Wasn't in the catalog yet. ;)
jaunty jetty
currently we don't have the physics to actually establish a warp field, and we don't have a power source large enough to do it; but they're improving the efficiency of establishment by magnetudes, and you can't make predictions about future developments in physics
dusty citrus
You can very much make predictions.
Generally you will overestimate how soon it can get here in any form of interest.
jaunty jetty
when Alcubierre first published this it took the atomic energy of jupiter to establish a warp field, and now it only takes the atomic energy of the moon
dusty citrus
The number of people who think they know something about this (at all) is suspiciously high.
jaunty jetty
as we get closer and closer to fissussion power, and it gets easier to do, and they figure out how exotic particles work, it's entirely possible that humans will abstain from self destruction for long enough to give it a shot
dusty citrus
You cannot avoid them, even in as small a population as the Adafruit discord server.
jaunty jetty
ok, you can't make negative predictions about physics, you can't say we won't ever figure a thing out, or discover a way to do something
you can say "we'll never know for sure what's in the center of jupiter", and there's a whole future of probabilities that you're wrong
dusty citrus
You can make very useful estimates as to the likelihood a class of event can or will occur, in the conceivable future.
jaunty jetty
and you have a very high probability of being wrong because you lack the understanding that leads to the discovery
dusty citrus
Bingo.
jaunty jetty
everything we have now suggests that pFTL is somehow possible, warp is just the possibility we know the most about currently
maybe we'll figure out wormholes
we know almost nothing about wormholes currently
last I heard, we're not entirely sure that wormholes actually exist, just that relativity says they could, but maybe somewhere else there's another mechanism that prohibits them
dusty citrus
I'm all for keeping Roger Penrose employed and teaching (if he still is).
jaunty jetty
he looks fun, but he's 87, so I'd imagine he's mostly retired
btw, pFTL: pseudo Faster Than Light, processes for travelling from one position to another in a shorter period of time than light requires, without violating the speed of light
dusty citrus
jaunty jetty
with warp, the space you're in is moving, you are not moving in the space, so you have a very low speed in relativistic terms but space is not constrained by the speed of light so you can move between the points faster than light can without dealing with time dilation
with wormholes, you travel an alternate route that abuses the shape of space to be shorter than a traditional route
dusty citrus
ducks back into the woodwork. ON a mission!
jaunty jetty
various fictions have also proposed shifting into an alternate space where the speed of light is higher or just speed is entirely different
late fulcrum
jaunty jetty
Stargate uses several of these, the stargates themselves establish wormholes through subspace, where the speed of light is very high, and the outbound gate disassembles the travelling object, encodes it into data, transmits the data in a high energy format, and the inbound gate then reconstructs them, so while in the wormhole the traveller is photons and travels at the speed of light in a place where the speed of light is much higher
there's also several forms of ship based transit, notibly hyperdrive, which does a similar thing but without the disassembly so it's still limited by the relativistic behaviors of hyperspace and therefore much slower
eh, there are plenty of examples of other civilizations in star trek messing things up royally by mishandling experimental technology
like I remember an episode where a klingon bird of war was experimenting with a prototype cloaking device that used a slight dimensional shift method to be 100% undetectable, but it went wrong and they got trapped oscillating between dimensions forever
and I feel like there was an episode where the cardassians were experimenting with a new disruptor weapon and it went wrong when the gun created a contagious slow acting atomic disruption effect that destroyed the ship and left the few who escaped slowly dying and infecting their saviors with it
if you consider the new movies, the romulans had a fricken ship covered in lazers with goop that creates black holes "for mining"
however, there was the episode of Voyager where Tom Paris made the Delta Flier go Warp 10 which caused him to devolve into a newt until time looped and then this time it broke
one problem I have with this thread is that there are a large number of humans in the borg, so logically the borg should have immediately become a way bigger threat

project idea, a tea robot
It'd be like a tower with a little platform for the cup (mostly so you put the cup in the right place), and an arm, the arm is able to pivot to one side by maybe 90 degrees, and on top there's a motorized spool with a slot in it.
You take the tag of the tea bag and put it in the slot, then there's a basic calibration process where you use 2 buttons on a keypad to move the teabag up and down to teach it the size of the bag and the length of the string, which it saves.
Then you give it a cup of hot water and select a preset for steep time and as if by heretical magic when the time is up it lifts the tea out, scoots to the side, and drops the tea bag into a receptical like a small plate or bowl; if it's bluetooth maybe you control all of this with your phone, and it sends you a notification.
Various sensors could make this easier, like 2 prox sensors so it can self calibrate, a load cell under the cup station, a camera to try and identify tea by it's packet. The toughest upgrade would be to make it more self sufficient
I can't imagine a maker building a device that can open a packet without damaging the tea bag and then locate and grab the tag to then attach to the machine somehow
wet imp
I've meant to build this for like five years
jaunty jetty
if only I had an erector set and some small motors
does the CPX have a prox sensor? maybe this is one of those perfect CPX projects
wet imp
Alternatively: a loose tea machine
jaunty jetty
there's a lot of ways that would be much more complicated; but I think the solvability is higher overall
wet imp
Yep
jaunty jetty
so, most tea bags are lightly colored, and the CPX has a bunch of bright neopixels plus a light sensor, maybe reflect light off the bag, measure the lux, and I guess you need to put the light sensor in a tube to constrain it's view but that could serve as a prox sensor
jaunty jetty
turn all the lights on and move the bag up and down until you detect a significant increase or decrease in lux; based on direction that's the top or the bottom, then find the other side; you want to have the light sensor roughly at where the waterline in the cup will be, which is difficult to predict
it's probably easier to use some actual sensors that are good at this, maybe have one on top as well to check the water level instead of making assumptions
vestal phoenix
Keurig Tea. Earl Grey. Hot.
jaunty jetty
oh good point, a loose-leaf machine can have multiple teas to choose from and could respond to tube-ladies
what's needed is a basic dosing system that doesn't destroy the tea
vestal phoenix
Ghost in the Shell geisha performing tea ceremony?
jaunty jetty
dosing is probably one of the largest problems not yet readily solved by the maker community
the best I can think of is a conveyor belt in a conic container that dumps onto a scale and then that scale dumps into a receptical
wet imp
Volumetric dosing in teaspoon-ish quantities seems okay
Conveyor belts are a worse idea than a spinning plate with a teaspoon ish cutout
jaunty jetty
tea is allocated in grams
wet imp
Scale makes it slow
jaunty jetty
since this isn't a continuous process I'm not that concerned with speed
keurigs are incredibly slow but you only use them a few times a day so it's fine
the problem with a sliding plate is it functions as scissors, so every time you use it you cut all of the tea that crosses the top of the plate. Over time you'll powderize a considerable amount of tea
the problem with paddle wheels (and conveyors) is they agitate the tea and will cause it to slowly grind itself down
the way they do it in industry is the tea is already collected onto a long conveyor belt, not in a big reservoir. They get the raw tea in bags, scatter it one time on the conveyor, that runs through an oven, then the conveyor splits up to sorting machines that put the result back on conveyors and eventually they get to the dosing system which drops the tea into grabbers that are also scales, when the grabber has enough it drops it's tea into a second grabber which does the same but larger, when it's full it drops it into a container.
You don't have any tea just sitting around in a bin being ground on other tea, all these things generally happen once so the wear is very limited
it's like the difference between shoveling gravel from one place to another vs putting it in a rock tumbler
maybe a vacuum system?
it'll be loud and unpleasant
what if static electricity.....
wet imp
Hahaha
jaunty jetty
like, use static to make a little electromagnet for tea where a little finger covered in charge pokes in and some tea comes with it
jaunty jetty
but the chops!
wet imp
Plate spins, tea falls into cutout, plate spins further, tea is transfered further without the dropper losing any more tea
Chops?
jaunty jetty
a plate with a hole in it is scissors
jaunty jetty
ok so, can this be solved at the other side, plate with a hole in it, shifts over so the hole is covered on top and can drop it's contents out the bottom, there has to be a thing on top that the hole moves under and that's what makes the scissors
can the thing that covers the whole be pliant in a way that it will keep most of the tea out, but anything sticking out of the hole is let through?
jaunty jetty
I think this is about the limits of theorycraft, need to do practical testing to figure out how this works
wet imp
I'm going to go do some practical testing
By making myself some gunpowder
I really like good loose leaf tee
jaunty jetty
gunpowder tea? why is that a thing? I noticed I have a container named that recently
how do gunpowder dispensors work
wet imp
Why? Because gang pao de sounds like gunpowder. And means freshly brewed
jaunty jetty
oh, that makes sense
jaunty jetty
this one dispensor seems to use a vibration system to move gunpowder grains through a horizontal tube connected to the reservoir, I guess that's good enough to prevent any shock or shear that could cause a detonation, but it's going to be trouble with tea that will tangle together
this advertising and training video has convinced me that the Hornady Lock-N-Load Autocharge Powder Dispenser is not capable of reliably dispensing the requested amount of explosives and Hornady believes this is an unsolvable intrinsic fault in trying to dispense granular product; also they're bad at planning because this guy was almost always surprized by the machine, or outright contradicting it
what I'm thinking is the fixed part is a bunch of spring loaded fingers with silicone on the outside and flexible silicone tips, each finger has a stop so they won't drop into the pocket, and maybe the upper part of the finger has ridges so it grips more strongly. Near the tip maybe there's a little hook situation where it's like
/
/
_>```
the fingers will help the wall to conform to the heap sticking out of the whole instead of being lifted the whole way acrosssince the dosing will definitely be inaccurate you'd probably want to dispense several times to create one serving of tea, and I think keeping the pocket small might improve performance in general
... but tea is so little...
if you're doing like 5~10 doses per serving then you can add or remove a dose to compensate for inaccuracy, but if it's just 3 or so I think you'd just be compounding the inaccuracy without any actionable recourse

a little puck sort of thing that you set on your counter in sight of your gas range, and it's got a ring of IR sensors positioned approximately at the height of the burners, so it can detect if any burners are on, and then it uses BLE to tell an app on your phone that does a few things
First, when you're home, and the stove is on, you'll have a constant notification about it
Second, if the phone leaves a geofence while the puck detects fire, an alarm goes off
4, you can check in the app any time, if you're home it will give you a meter of what the puck is sensing, if you're not home it will report the state when you left
so it looks like most flame sensors detect the IR emission of hot CO2, which has a wavelength between 4 and 5 micrometers
that'll work with natural gas and propane so good

but about those resistor values
to renew, if you could only have 5 resistor values, what would you pick
late fulcrum
If I could only have 5 resistor values? Hmm. 10Ω, 1k, 10k, 270k, 1M.
jaunty jetty
what's attractive about 270k?
also, thanks, it's very insightful that you skip everything between 10 and 1k
late fulcrum
I use the higher values (270k and 1M) for high-impedance stuff like weak pull-ups, static dissipation, and biasing). I could go with 100k instead of 270, I suppose (can parallel two 270k to get 135k, or put two 100k in series for 200k if needed).
While there is some use for 470k and 330k for current limiting things like LEDs, those can be had by paralleling 2-3 1k resistors. I'm fond of 4.7k for base current limiting, but 1k or 10k will generally do, and 2 10k in parallel would be 5k.
5k gives a nice round ~1mA into the base for a 5V supply.

A while back, a surplus outfit offered a sack of 1000 white LEDs for $4, so I bought a sack. The local makers quickly learned I was happy to give out handfuls of LEDs to people who wanted them.
While designing version 2 of a project I'm working on, I think I discovered why I never got version 1 to work. Apparently I hadn't been looking closely enough at part numbers, so while I got the size, color, and polarity of my LED displays correct, I had bought some with a variant pinout (-12 instead of -11), and (of course) those were the ones I happened to put in my breadboard. Now I'm tempted to dig out the -11 parts and see if it works with those.

apparently some group is building a system of robotic cranes that will lift, stack, and unstack concrete blocks as a large scale electrical storage system, when blocks descend the crane uses regenerative braking to generate electricity
they mention in the article, totally out of nowhere, that wind is a concern; but this doesn't need to be outside, they could create a cylindrical hole in the ground and shift things internally, plus the gantries could run from a pinion in the center to a rail system around the outside along the top, freeing more space in the center and allowing the arms to move separately

To add a little to @proven olive -- bringing up money with family tends to be source of stress. Especially in this context.
It's also not wrong to want more. Desire to have more, do more is what propels the world. So, where do we go from here?
I'd encourage you to reframe the issue: ask yourself, why do I want more money? So I can buy more? (if so, what am I lacking?) So I can do more things (concerts, events, etc)? So I have a safety net if things go sideways?
These are all very legit concerns, and they vary from person to person.
Now ask yourself: What can I do to fix that other than asking for more money directly?
Can I ask to take on more responsibilities at home for a greater allowance?
What can your folks do to assuage a concern for financial safety (can they help you if times get bad, can they help you do something to help you save money?)
Is it feasible to take on a job or an additional job for additional income?
And if all of this hypothetical questioning is for naught -- then ask yourself: What can I do to ensure that money isn't an issue for the future?
Is there a career field that I enjoy as well that pays very well? What skills can I build for that even now?
What soft skills can I learn to help get my foot in the door? The World Wide Web + youtube + online courses are great for this. Resume building, interview taking, technical writing, public speaking, etc. These skills will help earn you mad dollah dollah yo, regardless of which field you choose. And moreso, not having them will cap you prematurely.
I won't go into detail, but there entire lists of "essential life skills". Everything from laundry to 401k management to mortgage basics. These might not earn you money, but they'll keep you from getting swindled.
And trust me...there are too many people who delightfully prey upon ignorance and inexperience.

I discovered that if you remove a cpu from a laptop while it's on
the cpu will be perfectly fine

cause I went and got my s478 pentium 4 out of a storage building.. and tried to put it in my old laptop(chipset apparantly wasnt compatible so wouldnt boot) so I put it's old cpu back in... but after trying to boot it with the p4.. the battery got a charge... and I thought I fried the original cpu after putting it in with the battery in
turns out I just forgot to lock it in, .. and that's why it wouldnt boot even with the old cpu
cause I went above and beyond on ebay to find a new cpu... then I went back to the laptop.. realizing the cpu wasnt locked down
and I facepalmed so hard my hand went clean through my head.. and I locked it in
and it booted up
moral of the story.. dont forget to unplug all power sources from a computer before working on it.. and always lock the cpu in

I have the soluton to global warming, we build a gant shutter disk in space, that spins really fast, and has panels that we can shift around, and PWM dim the sun
we'll have to make it 60Hz so cameras work correctly in america and parts of Japan
as dumb as that sounds it kinda seems like a thing that could be done, it'd be very difficult and take a fraction of the earth's work capacity for a long time, but the other options are less doable, like we really have no practical option to sequester greenhouse gasses at a meaningful scale
and the disk wouldn't even need to be the diameter of the earth, even the penumbra will be meaningfully reduced flux density
jaunty jetty
if my math is correct the shutter disk would be ideal at about 8.6e5km inward from the earth, and then it's shadow would cast on the entire surface. This is the position at which it can be the smallest and still do that, but we probably wouldn't want to build the shutter big enough to block out the entire sun, just enough sun to make a difference. It would at that position need to have a diameter of 15.8 megameters to block the whole sun, or about 5 megameters to block 10% of the sun
for reference, the earth is 12.7 megameters in diameter
late fulcrum
That's a lot of rotating mass, and as it pivots to be in the correct position as the earth orbits the sun, it's going to try to precess. Countering that is going to be tough.

if it were at L1 instead of prenumbra make that 3.6Mm

a company was trying to sell those maybe 5 years ago as an alternative to regularly changing the batteries in your smoke alarms
idle iron
it says it is "wifi connected cloud-enabled 9v battery"
i think what it does is just detect when power is being used and send you alert
jaunty jetty
that's a major upgrade, before it just told you when to replace the battery
I'd still say that at over 30$ per battery, the reduction in safety of absolving the home owner from routinely confirming their smoke alarms are working is not worth the feature set
(and note, these are primary cells, non-rechargable)
idle iron
I wonder if you can take it apart and use its inners for something else
like instead of detecting if the 9v is using power, check if something else is
jaunty jetty
I bet that would be very difficult, but you can probably build a compact wifi battery tester using an ESP32, or ESP8266 with an ADC network
all you need is a voltage divider and an analog read pin or ADC
idle iron
I should get a wi fi feather, i dont have one yet. When the m4 feather is in stock again maybe ill grab both
jaunty jetty
the M4 doesn't have wifi
idle iron
why id grab both lol
jaunty jetty
ah
wing idea, kinda took a while off these; an ESP module on a wing but only wired up to serve as a wifi slave via SPI or I2C
there's probably other better ways than to slave a fully functional battle processor for such a minor feature, but there's currently zero wings that will give a feather wifi or BLE
and neither the M0 Express or M4 Express are available in feathers that have connectivity modules built in
idle iron
would this work? https://www.adafruit.com/product/3061
jaunty jetty
that's an M0, not express, so it doesn't have the 2MB flash chip and therefore has a limited capacity to be used with CircuitPython, MakeCode, or other fancy things that take up a lot of space
idle iron
i can use Arduino, kinda lol
jaunty jetty
arduino is fine but when you start to do things on the network C starts to get really complicated in ways Python is built to make simple
the M0 Express uses normal SPI on an internal bus, so maybe there could be an Express wing with maybe several flash chips, but that would interfere with using the external SPI bus
on the M0 wifi, the ATWINC1500 module is on the external SPI bus
idle iron
ty for info
jaunty jetty
the feather M4 has it's flash chip on an internal QSPI bus so external SPI is free to suport an ATWINC module
that said I think the ATWINC1500 is defunct now? seems like the library support has faltered and it's a real pain to use
idle iron
I have not used wifi yet
jaunty jetty
so, all of the M0 have their connectivity module on the external SPI bus. I assume all of them make proper use of a selector pin so you can have multiple things on that bus but it really complicates the code to have to be considerate of not being able to just access the flash whenever
I wonder if I could just take the eagle files from the M0 atwinc and delete the M0, charge controller, USB port, etc

one of the casters on my cat litter is failing, and it's causing a lot of drag, so now the belt is slipping and the pully is slowly grinding off the belt
vestal phoenix
Cat litter box rover that follows the cat around? I can see some engineering challenges.
jaunty jetty
it's stationary, there's a barrel rolling on 4 casters with an agitator system
I'm going to have go replace that soon but I can't, and ideally I need to rebuild the carriage again so that caster and the other on the same side are fixed; and if I'm buying new casters I should get ones with actual bearings instead of plastic on shaft
vestal phoenix
Harbor Fr sells a moving dolly that's cheaper than if you were to buy the set of casters and wood to make the frame. And they always have a discount coupon available.
jaunty jetty
maybe yea, I'll have a look; but I need a fixed wheel, those dollies usually have 4 spinners
the way I have it there's 4 casters, each is swung so the wheel is outside of the square formed by their mounts, then the weight of the barrel is supposed to maintain alignment; but it turns out that on the downward size of the barrel's rotation the self alignment force is very weak so any kind of disruption will push them out of stability and they'll start to resist alignment
I'd either need to mount those casters on a vertical surface or use a fixed wheel. Luckily I only need the fixed wheels to be aligned with each other and close enough to square with the spinners, on the up side of the rotation the spinners self align perfectly
vestal phoenix
if you have the rock tumbler/compost turner arrangement, many ways to fix the casters from turning.
jaunty jetty
yea, the tough part is a design that doesn't require high precision
I also need to design some kind of light weight saloon door that will force the one cat to actually be all the way inside before she pees
vestal phoenix
Maybe theres some research by temple grandin on how to make one.
jaunty jetty
temple grandin?
I'm figuring I just need to find a reasonably priced spring hinge that doesn't push so hard it stops the cats, but does push hard enough to hold the doors closed while they rotate with the barrel

I hope you've got a solid chiller in your HVAC

Has the power company sent you a thank you card, for putting their kids through college?
karmic kite
its 2degrees Celsius here, just less reason to turn on the heat 😛
jaunty jetty
there comes a point when you still have to run a chiller even when below 0C
karmic kite
I'm sure we'll find that point eventually.
looking at getting a blade server and migrating all my servers into that

jaunty jetty
got any local datacenters? they're more common than you'd think
also difficult to find since obscurity is a kind of security
karmic kite
I mean I like having physical access to my own data, and I find its cheaper not to rent space
grave crest
I'm just saying, as much as I enjoy running my own private cloud at home, I keep it to a handful of devices just for the resource consumption sake + manageability sake.
2x synology NAS boxes (replicated)
1x getting-older ThinkServer tower (3ghz xeon, quad core total) as an ESXi host.
[that will be replaced eventually with a pair of Intel NUCs or custom tower with an obscene amount of resources]
Primary driver computer (laptop/desktop) + tablet + phone.
When I was in college, I used to run probably 5-6 physical boxes. Kept the Rochester windows open year-round.
Now? I pay for my own power. I'm busy with work + life, less time tinkering around for the sake of it -- any tinkering I do needs to be focused: what do I want to accomplish & learn from it?
And having a ESXi host with beefy specs means I can spin up any service to play around on-demand. Bare-metal hardware tinkering? No thank you.
The Synology NAS arrays are feature-filled and turn-key out of the box. They're so easy to work with, and require none of the troubleshooting + validation that a FreeNAS would require. I can set them up in an afternoon....and spend the rest of my time with family and friends and cat videos on Youtube 😃
jaunty jetty
local datacenters provide physical access on demand
karmic kite
I mean I don't mind having the devices around, studying for ccnp and ccna the other advantage is watching different traffic route. Most of these boxes are varying game servers for what ever our friends group is playing at the time, the file servers we both keep as redundancy to our code projects, and then varying os's for testing projects
so most of it could be done with VM's
and I used to have a bunch on AWS but that was starting to get to be a hassle
grave crest
VMs are amazing. ESXi/HyperV...even VirtualBox can do so much.
I'm not joking -- in enterprise environments, I've seen a Virtualization setup (compute + transport + storage) that was 6U of rackspace replace the footprint of 3x 40U cabinets (120U total) of legacy hardware -- and they were thrilled at the performance increase too.
Imagine all that power, cooling, maintenance....totally a non-issue.
Granted, consumer gear doesn't yield such dramatic returns, but when you can consolidate 3-4 physical boxes with a home-built ESXi host....that's fewer boxes to maintain. To cool. Better usage of available resources too.
plus, all the benefits of a hypervisor such as snapshots and backups.
jaunty jetty
can speedfan successfully control fans, if it's running on a VM?
grave crest
I honestly don't know, you'll have to look into if Speedfan has any software/plugs available for VMware/etc
Every hypervisor is different -- costs, features, limitations, etc
It's something that requires a fair bit of homework before implementing -- but VMWare's ESXi is the big dog currently. They're also somewhat costly, depending on which license you use.
There still may be free/limited use licenses which won't impact a hobbyist/home-useer, but won't function well for an enterprise-class business user.
karmic kite
The host machine still controls the fans
I'm hoping to find a blade server on ebay to be able to handle it
currently I cycle through vm's as I need them

@karmic kite you might be able to arduino-program a fan controller, then have a vm and the arduino talk over serial

I kinda am a fan of controllerless design... Id be tempted to set a thermistor to a pwm control circuit but I feel like the on board controllers still will work better:P
jaunty jetty
the thing is you don't want a linear control response
you want to ramp up from 0, plateu at a low level, maybe have a few plateu ramps, and then curve up to 100%

Of course nowhere near as intricate but it works pretty well. Helps that the ARM M4F has a floating point accelerator, so the thing runs at over 30 FPS

Aha, thanks. And yes, I had to add it for the atmosphere 😉
abstract violet
would this be possible in Circuitpython? and the eventual Adafruit Handheld Gaming Circuitpython thingy!
royal crag
90% sure it can be done. IDK if the M0 can keep up performance-wise, but the entire thing was written in "arduino" so it can be ported easily
The entire thing is derived from a 3D raycaster I made in C for the PC. I have some optimizations there that I wanna implement into the MCU version
abstract violet
oh id think this would be at least M4
not sure of the difference between the M4F vs. SAMD51 M4
royal crag
The F suffix indicates the hardware floating point accelerator
Haven't read up too much on it but I'm guessing single-cycle math operations
abstract violet
does that factor in the performance on that sort of application? sorry lotsaquestions/noob here
royal crag
All good, glad to share 😄
For this, yes. I do quite a bit of math for the raycasting. It's all multiples and array traversing
And then a lot of ugly value mapping for the textures
abstract violet
ooh, the NRF52840 is a "M4F" i think...
royal crag
Let me look this up too...
Yeah that core is an M4F at 64Mhz. The MSP432 in the video is only at 48Mhz ("only", hah)
abstract violet
ooh with some room to spare.. for some wireless gaming action 😮
royal crag
Oh yeah, plus with some optimizations to the code you'd have plenty of CPU time to do some more neat things with it!
I'm making a second revision of that device with a PIC16, which is an 8-bit processor with no accelerator of any kind. Not sure if I'd be able to recreate the same thing, but it'd be fun trying 😅
abstract violet
now I'm curious, have you built other similar things? @royal crag 😮
royal crag
A few, but I'm terrible at documenting these things...
allow me to scour my archives for some photos...
abstract violet
I'm actually not sure which mcu adafruit is secretly planning to use for their gaming device but :}
yes please 😄
royal crag
So here's the device in all its glory. Was planning on making it a fully-fledged PDA with a battery, wireless, etc. But the MSP432 isn't the easiest to get started with...
Plus it needed two power rails, it still used a full-fat "launchpad" carrier board, and it was bulky.
Plus the inexperienced me decided to use solid core wire... that was fun, didn't finish that without any burned fingers.
This is the second version I'm working on
Much smaller, but no joystick or gaming specific controls
Right now it's in the breadboarding phase, to make sure I can drive all the peripherals correctly before soldering it all together of course
abstract violet
@royal crag wow! this looks awesome, can see a 3D printed case and bam. Nice wiring job anyway 😄 maybe have the soldering equivalent of a thimble xD (if it exists..)
royal crag
I could certainly use one of those, yes!
This was one of my more complete projects... https://cdn.discordapp.com/attachments/171968614067470336/464554821857574912/P_20180705_174400_vHDR_On.jpg
A little game of Simon with a PIC12 written completely in assembly
abstract violet
oooh complete with sound
royal crag
I'm very close to making a case for that too
abstract violet
ofc
royal crag
That was a little tricky to do... Had to utilize a lot of peripherals and interupts to get it to behave like the original
abstract violet
is that powered by a cell battery?
royal crag
Currently not powered by anything https://cdn.discordapp.com/attachments/171968614067470336/464554584636129280/P_20180705_174352_vHDR_On.jpg
But a cell battery would work well
That PIC is rated for 2.0-5.5 volts. Very flexible, and no need for a boost/buck converter to keep voltage
abstract violet
have not played around with a pic before
royal crag
They're... different, I should say
Getting into it was cheap if you have the right stuff. $4 worth of parts and you can build a simple serial port programmer for them
Then just read up on MPASM, download the assembler for free, and off you go!
Though the older/lower end parts don't have in-circuit debugging, so if something's not right you may have to resort to an emulator to see what's happening
Also if you're using all the pins like I am, it's impossible to attach a debugger
abstract violet
looks really nice and compact though, and minimal use of components a +
royal crag
Oh yeah, would you look at that!
But of course that one's so much nicer, proper keypad, colour LCD, case, everything 😆

Second form seems likely to be something you have to interact with ( a database ) to become aware of it.
Well my feeling is it should be transcribe-able by anyone (especially not the intended or initial recipient).

I've read about them. ;)
jaunty jetty
my left eye is about twice as bad as my right eye, but they're mostly pointing in the right directions
dusty citrus
I've got a 39" display viewed at about five to seven feet and that's STILL not enough for either eye; when I put on the 1.25+ diopter drug store glasses, it addresses the right eye (but feels wrong) and the left is worse than unaided vision. ;)
I don't notice this for viewing motion pictures but text exposes the vision defect immediately.
jaunty jetty
well, knock out the left lens
dusty citrus
you crack me up. thats a pretty good idea.
The left eye, unaided, is better than the right eye, unaided.
They reverse when I put the diopter in front of both.
jaunty jetty
is getting an eye exam off the table?
dusty citrus
I think 1.25+ diopter was not meant for vision at 6 feet. Probably at 20" or so.
It shouldn't be but realistically it'd be unusual for me to give in and do something like that.
jaunty jetty
it's not for any specific distance, it's to correct the eye

What I Don't like is the lack of a firm commitment up front.
jaunty jetty
what do you mean?
dusty citrus
Tell me "IT's eighty five dollars to you, by the time you walk out the door" and I Might walk IN that door.
The diopter system is magnification.
I don't want to be on the hook for more money than I have budgeted, for anything I ever spend money on.
jaunty jetty
you can establish the cost of an eye exam up front, have the exam, pay what you agreed on, and leave
dusty citrus
Lots of vendors construct their exchanges so that knowledge up front is essentially unavailable without some strong form of consumer 'pushiness' exhibited.
I don't like that game. At all.
jaunty jetty
the price of your lenses should be fixed, it's based on your prescription, most stores have a stock of preground lenses in a diversity of parameters, when you ask for glasses they take the two they need and cut them to fit the frame you like
and of course every frame has a totally arbitrary price
dusty citrus
If they advertized the amount I'm willing to pay they'd get so many takers they'd run out of business due to lack of profit and high demand.
jaunty jetty
at every step it's possible to know exactly what you would pay, but not necessarily how much the next step would cost
dusty citrus
Haha. Thanks.
Thats' what I'm talking about.
It's a game I do not wish to fund in any way.
jaunty jetty
having good vision is worth it
just break it out into a week or two, start with the eye exam, it costs one thing for everybody
dusty citrus
Those are big hurdles for me.
jaunty jetty
how about this, a good shop gives you your prescription on a sheet, and then you can do whatever with that
like go on amazon and buy 2 pairs of glasses that are close to each eye and build some frankengooglers
there may be a shop near you that will put lenses in a frame for very cheap, and you can buy frames online for much cheaper than in store
dusty citrus
I wear two pair one over the other when I need more magnification than one can provide.
I spent an overnight at the expense of a well-known race car mechanic (who now does consumer repairs on expensive cars) helping with his computer troubles. He's a friend of my brothers.

You can always visit your local Lions club, many of them offer free basic eye testing (it's a cool gadget, takes about 30 seconds). Armed with that, you can order glasses inexpensively online.
jaunty jetty
that's a different thing
that's an eye health exam
to get a prescription you have to do the thing with the fliping bits and reading off a chart, but some elements of an eye health exam can get them in the ballpark faster
late fulcrum
To get an accurate prescription, you have to do all that, but you can get a quick-and-dirty prescription that way. An eye health exam by a professional is a really good idea, but I mentioned the alternative for folks that don't want to blow a lot of bucks and just want to see better.
If you're curious, this is the device they use. It uses visible and infrared light to calculate the focussing characteristics of the eye, then computes the reverse transform to yield the correction needed. http://www.iscreenvision.com/
I gave it a whirl shortly after I'd had a professional eye exam, and the results were reasonably close.
Also useful for getting prescriptions for babies who can't talk yet, let alone read an eye chart.
jaunty jetty
ah I was thinking about the thing they have at the eye doctor that also takes about 30 seconds

I used to photograph people every day, for their passport photo. Many did not think they looked 'right' without their eyewear.

if you think you're going to end up wearing them all the time then pay attention to the nose thingies. I have two pair, the pair I like more is all resin square hornrims but because of that the nose pads are integral and the way they sit on my nose becomes painful after a few hours. The other pair has the little plastic bits on a bit of hard wire, I need to have them adjusted but they sit more on top than on the sides
