blkhawk··on Someone got an LLM running on a Commodore 64 from 1982, and it runs as well
If anyone wants to try it with an esp32:

https://github.com/DaveBben/esp32-llm

needs a board with PSRAM but they are surprisingly plenty these days - almost standard. I tried it a few months back.

blkhawk··on AI's energy footprint
I find that message very curious because the message itself clearly does not cost much but the machines it is send on do. So the more messages that are send the less the messages will cost.
blkhawk··on AI's energy footprint
the numbers in the article are all over the place. I mean the article seems to try and some of the more general calculations on paper should work out but especially the image gen ones I can sorta disprove with my own experiences in local gen.

Even were it matches sorta (the 400 feet e-bike thing) that only works out for me because I use an AMD card. An NVIDIA card can have several times the generation speed at the same power draw so it all falls down again.

And the parameters they tried to standardize their figures with (the 1024x1024 thing) is also a bit meh because the SAME amount of pixels in a different aspect ratio can have huge variations in gen speed and thus power usage. for instance for most illustrious type checkpoints the speed is about 60% higher at aspect ratios other than 1024x1024. Its all a bit of a mess.

I loved that show. It showed how children deal with new technology different from how adults deal with it. It predated even google glass by half a decade.

blkhawk··on The Awful German Language (1880)
yes, this can cause even major-ish UI issues - like in android where this happens:

cut,copy,paste auschneiden,kopieren,einfügen

this can break the UI so you have scroll on a popup just to copy a piece of text because google put "copy" last in the selection.

blkhawk··on Nextcloud cries foul over Google Play Store app rejection
yes, exactly - it has an "AutoUpload" function that worked super well. Make a photo and by the time you put the phone down its on a folder on your desktop read for say putting something on eBay.

it stopped working well or at all over the last 2 years or so. I think if a simple "allow access to the photo folder" would have fixed it they out have used it. maybe it doesn't get the events when a photo is made?

any idea how i could implement that for comfyUI on the 9070? Going to try to apply whats in the reddit post to my venv and see if it does anything.
blkhawk··on LTXVideo 13B AI video generation
I have a 9070 XT... rockm ATM is unoptimized for it and the generation speed is less than what it should be if AMD isn't fudging the specs. Also the memory management is dire / buggy and will cause random OOMs on one ruin then be fine the next. splitting workflow helps so you can have one OOM crash in between. VAEs also crash from OOM. This is all just software issues because vram isn't released properly on AMD.

*OOM = Out Of Memory Error

I think AI could actually makes it fairer for the average player because it "smears" the time a bit to a general "vibe".

That said I too was a bit annoyed by how it rendered the byzantine empire. I thought Carthage was meant. So i was over by a thousand years.

blkhawk··on Mere weeks after Starship's breakup, the vehicle may soon fly again
The issue is that he is doing actual damage because it turns out that what was thought to be an aspirational goal (going to Mars) is the actually only goal. That means all the uses this new capability has become superfluous until that goal is achieved.

To me it became clear he is actually a moron and there is no deeper plan when the aspirational starship concept wasn't paired with him pointing out the other advantages it has.

For example:

* the estimated useable m³ capacity makes a special variant of a starship the equivalent to the ISS in capacity - now imagine docking 4 of those to a HUB. And that is without reusing the wet-workshop concept of space-lab.

* for the same reason nobody point out that it makes zero sense to use a starship as a landing system and not turn it into an instant moon base. The wet workshop concept applies here as well.

That is just two ways starship could be used as soon as it is orbit capable - Neither would need atmospheric re-entry

blkhawk··on E Ink’s color ePaper tech gets supersized for outdoor displays
RE: the external clock - in my setup I got the power draw down to ~24µA with just a crystal but its possible that a completely external wakeup could be lower. Not that i think it makes a difference with that dev board :)

You inspired me to redo mine since I saw a new type of colour e-ink display (Spectra C6)

In nat. gas this is possible - its called pyrolisis - as an alternative to steam reformation it is generating pure carbon and hydrogen instead of the CO2 and Hydrogen that steam reformation does.

Its main downside is that it takes more energy so you get less usable energy out of the process.

You can do it with other organic fuels as well and the simplest process is making charcoal from wood but its not as clear a way to separate out carbon there.

blkhawk··on E Ink’s color ePaper tech gets supersized for outdoor displays
I made my own version of this and I am seeing a lot of interesting choices so I am intrigued. The lack of soldering means you probably don't do that normally.

I find it wild that you used a dev board because the LDOs on them are most of the time very bad and you do seem to use 5V instead of bypassing that. The type you get normally uses 1mA just sitting idle.

Why did you use an external RTC instead of just soldering a 32.768khz crystal to the esp32? Okay if my assumption above is correct that answers that. but the external wakeup has no real advantage in power draw.

The relay eats some current and a mosfet in its place would probably be better. I assume you added it because the e-ink hat has no proper shutdown. From the looks of it you can just bypass the BUCK converter on it so just run it off 3.3-3.6v. There is a smaller BOOST converter in there that might still waste power so the mosfet might still be needed. This beings me to my next point:

you can completely do away with the DCDC boost converter by using a LiFEPO4 battery. All you need extra is monitor the voltage and have your display warn once it falls below 3V.

Anyway 9-10 months is remarkable for the LEGO approach.

blkhawk··on Order Declassifying JFK and MLK Assassination Records [pdf]
Maybe its truly a nothing-burger. even if released uncensored the most salient information would be details about how the secret service deployed and what they did wrong? Personally I think that is probably the most likely thing that would be still considered classified even if the details are completely obvious.

I mean most classified information is classified because its classified. By that I mean it is classified because nobody declassified it. That gets you hilarious press conferences like that navy UFO thing in trumps last term where the spokesperson could only say "the US does not have the technology to build a flying object like this" (paraphrased from memory).

I am pretty sure an analyst looked at the footage and identified a sea-bird and the US does not have the technology to build a bird exactly. But analyst output is automatically classified so.....

blkhawk··on Using ChatGPT is not bad for the environment
I did a bit of research and even water just "involved" in the process is counted as used in this context. For instance river water that is used for cooling and returned is counted.

I think these sort of graphs are simply misleading and should not be used.

blkhawk··on Using ChatGPT is not bad for the environment
The one near here just has heat exchanges. But even if all the others use evaporators then potential water usage is extremely misleading because its not like the water is consumed - its just temporarily unavailable.

Also why doesn't uploading a 1GB file to my NAS boil a liter of water? are maybe all the switches and routers used between me and the datacenter water-cooled? I mean I can see such switches existing but I don't see them be the norm. Why doesn't the DSLAM on the Street outside emit steam. Is there maybe one bad switch somewhere that just spews steam?

What I am saying is that at least that graph is without further explanation... bad.

blkhawk··on Using ChatGPT is not bad for the environment
what does "water used by data center" even mean? Does it consume the water somehow? What does it turn into? Steam? So uploading a 1GB file boils away nearly 1 liter of water? Or is it turned into bits somehow in some kind of mass to energy conversion? I sorta doubt that. Also this means data centers would have cooling towers like some power stations. Are we talking about the cooling towers of power stations?

I think at least that graph is complete non-sense. I will try and have chatGPT explain it to me.

blkhawk··on Bypassing regulatory locks, hacking AirPods and Faraday cages
Then don't bloody call it a hearing aid then in those countries - call it "adjusted transparent mode with equalizer". Stuff that coincidentally works as a hearing aid is not regulated as far as I can tell anyway simply because I never heard of a government that would confiscate an amplifier with an equalizer function build in as soon as somebody plugged headphones and a microphone into it.
blkhawk··on IRC Today hosted IRC bouncer
well I am completely with you there - but you have to remember what the words "Corporate Firewall" might mean and that the only thing apparently protecting us from a Russian takeover is closing off all outgoing ports except 80 and 443 :)

I don't have an IP where i can just run Quassel on 443. Using it over websockets on a subdomain might indeed solve my troubles.

blkhawk··on IRC Today hosted IRC bouncer
It started locking off basic features behind paywalls and is nagging you about it. Before the rise of discord and in the professional space teams it also started to close off external API gateways to for instance IRC.

Its the basic enshitification playbook really. They got steamrolled during COVID by zoom and later teams somewhat interrupting the process.

blkhawk··on IRC Today hosted IRC bouncer
personally I think discord is shit - I wish it would go away. IRC is a lot more resilient towards takeovers and enshittification. look at what happened to slack.
blkhawk··on IRC Today hosted IRC bouncer
That is for web-IRC. Its getting to the same result slightly different than via native apps. Has advantages tho.
blkhawk··on IRC Today hosted IRC bouncer
Quassel IRC is another solution for this - it also works extremely well with the only downside being that it isn't tunneled over HTTP/S by default. Oh and it is self-hosted.

I can recommend it for a Windows/Linux/Android hybrid environment from personal experience
