buildbot··on Bikeshedding, or why I want to build a laptop
Yes, if they did not solder on the memory it would use more power. The longer the lines are to your DRAM, the more impedance there is and you need higher drive power on your memory controller. LPDDR has been soldered forever as far as I know, though with the introduction of CAMM (compression attached memory modules), this has changed. I don’t know but I would bet money CAMM is still higher power for less bandwidth than DRAM packaged on the SoC base die or however apples does it.
buildbot··on My car charger can boil water really fast [video]
It’s a good point but there might be a pretty big difference in force because the ladled pint of water is not contained on any axis. A pint of water in a cup, with up as the only exit, subjected to the full current of a 3 phase 480v circuit is probably going to generate a good size jet of steam straight up.
buildbot··on Z2 – Lithographically fabricated IC in a garage fab
I was like, this seems like a small machine could automate a lot of it, now that the number of steps are down to around what ECN2 film dev requires…

Of course, that’s what they are doing it seems! https://atomicsemi.com/

Woah, “wafer level optics” sounds really fancy

buildbot··on Gemini 3 Pro: the frontier of vision AI
I’m a little surprised how open the help links are… I guess that if need help logging in you can’t be expected to well, log in.

That might be an interesting training set, a bunch of mazes…
buildbot··on A Cozy Mk IV light aircraft crashed after 3D-printed part was weakened by heat
I think an extended quote shows that this was a really bad call:

“ The aircraft owner stated that as the glass transition temperature listed for the CF-ABS material was higher than the epoxy resin, he was satisfied the component was fit for use in this application when it was installed. A review of the design of the laminated induction elbow in the Cozy Mk IV plans showed that it featured a section of thin-walled aluminium tube at the inlet end of the elbow, where the air filter is attached. The aluminium tube provides a degree of temperature-insensitive structural support for the inlet end of the elbow. The 3D-printed induction elbow on G-BYLZ did not include a similar section of aluminium tube at the inlet end. Tests and research Two samples from the air induction elbow were subjected to testing, using a heat-flux differential scanning calorimeter, to determine their glass transition temperature. The measured glass transition temperature for the first sample was 52.8°C, and 54.0°C for the second sample.“

buildbot··on Valve reveals it’s the architect behind a push to bring Windows games to Arm
Perhaps, I have yet to experience anything like what the older games had though.

It might just be the game too - I do think the auto aim is a bit high because I feel like I make aimbot like shots from time to time. And depending on the mode BF6 _wall hacks for you_ if there are players in an area outside of where they are supposed to be defending. I was pretty surprised to see a little red floating person overlay behind a wall.

Speaking of Anti-Cheat and secure boot, you need SB for Battlefield 6. The game won't start without it. So it's happening!

I don't hate the lack of cheating compared to older Battlefield games if I am going to be honest.

buildbot··on John Giannandrea to retire from Apple
To be super pedantic, wouldn’t the interface to a shell itself be a Command Line Interface? ;)
buildbot··on A new AI winter is coming?
People learning to code always have had those questions and issues though. For example, “git ate my code’ or “I don’t believe in python using white space as a bracket so I’m going to end all my blocks with #endif”
buildbot··on 1GB Raspberry Pi 5, and memory-driven price rises
Indeed…
buildbot··on 1GB Raspberry Pi 5, and memory-driven price rises
Indeed, it makes mini computers with soldered ram actually end up being quite cheap by comparison. HP will currently sell you 128GB AMD or Nvidia boxes for 1.7-2.8k depending on your flavor of choice. Not ECC though.
buildbot··on NVMe driver for Windows 2000, targeting both x86 and Alpha AXP platforms
This does work on a compaq DS10. You can't boot directly from it but linux will see the nvme disk right away from a livecd.
buildbot··on Apple Desktop Bus Protocol (2021)
Oh is that why I2C seems to just hang/break whenever I use it for a DIY project? Does everyone just reset the bus all the time?
buildbot··on PS5 now costs less than 64GB of DDR5 memory. RAM jumps to $600 due to shortage
It's not - ECC RAM still means real, between the RAM and CPU ECC. It's literally an extra 8 bits per channels, for an extra 16 bits per dim. 40 bits vs 32.
buildbot··on Datacenters in space aren't going to work
Which is why vacuum flask for hot/cold drinks are a thing/work. Empty space is a pretty good insulator as it turns out.

It’s a little worrying so many don’t know that.

buildbot··on Unpowered SSDs slowly lose data
Making sure all your important data can be read and is checked at read is like zfs scrubs sole purpose. Seems like at least a monthly scrub is a very good idea for SSDs.
buildbot··on We stopped roadmap work for a week and fixed bugs
They float around on ebay! Software might be an issue.
buildbot··on PS5 now costs less than 64GB of DDR5 memory. RAM jumps to $600 due to shortage
I have not seen that yet DDR5, I think the signal integrity requirements are too high now to even have unused pads open. Most sticks don’t appear to have many traces at all on the top/bottom sides, just big power/ground planes.

Also with DDR5 each stick is actually 2 channels so you get 2 extra dies.

buildbot··on NTSB report: Decryption of images from the Titan submersible camera [pdf] (2024)
Speaking of which I heavily recommend reading interview the prime ancestor comment to this chain linked. It’s really clear he knows what he is talking about.
buildbot··on Ubuntu LTS releases to 15 years with Legacy add-on
Not that you’ll agree, but cleaning the house sounds more like running rm -rf /tmp and docker system prune than upgrading from idk, bullseye to bookworm. Let’s call that a bathroom remodel? So sometimes you live in a historic house and the bathroom cannot be remodeled or changed because it’ll fall through the floor or King Louis the XV used it once. In software, the historic house could be the PLLc firmware controlling the valves in your nuclear reactor cooling loop.

It honestly makes sense. You are paying for the pressure engineering, and can take advantage of an off the shelf camera system. Maybe use a special lens or filter or something but why bother customizing the software/hardware of the camera much.

They probably should still know what it's doing though...

buildbot··on Android and iPhone users can now share files, starting with the Pixel 10
Is anything but the zip code actually checked ever? Besides the number and cv2 or whatever.
buildbot··on 'Calvin and Hobbes' at 40
Same here, though I started bloom county a lot later. Almost all of my 80s cultural knowledge stems from that comic haha…
buildbot··on How two photographers transformed RAW photo support on Mac
The OS supports it is all I was saying.
buildbot··on How two photographers transformed RAW photo support on Mac
It’s capable of doing so but is not the default for the built in camera app
buildbot··on How two photographers transformed RAW photo support on Mac
Natively it’s coming off the sensor like everything else, raw 8-16bit values. The OS then takes that stream and packages it into whatever, which on iOS can be a DNG, optionally pre-debayered with ai stuff in it (proraw), or just a standard, bayer mosaiced DNG, or JPEG, or HEIF, or JPEG XL.

Depending on the RAW, a conversion to DNG may not be lossless.

buildbot··on Europe is scaling back GDPR and relaxing AI laws
If I am not mistaken, the anarchist school of thought is okay with governance and even governments, but not with the concept of the state - an entity that exists to enforce governance with violence. For example, https://en.wikipedia.org/wiki/Anarchy,_State,_and_Utopia

I’m not 100% sure though.

edit - a (vs. the) school of thought is more accurate.

buildbot··on Living my best Sun Microsystems ecosystem life in 2025
I love my ultra 45, it’s certainly the best looking of the early 2000s unix workstations!

I lucked out and got a system with 16GB And 2x procs, added in the XVR-2500 and PcPro to play with. It’s also ex-Lockheed Martin which is fun/mildly alarming!

Since this thread is likely to draw knowledgable sparc people, there’s a totally unrelated question I have - I have a sun blade 150, and was looking around on the motherboard. There are few jumpers that say things like “x86 debug” or x86 rom something - and the socket is technically 378… and from what I can research, the chipset worked with x86… Was there a point at which the sun blade motherboard was setup to work with either sparc or x86?!

Not so crazy given AMD made a chipset that worked for both alpha and x86, and HP had the zx1 chipset that worked on itanium and hp-parisc?

https://en.wikipedia.org/wiki/List_of_AMD_chipsets 750/760 both work for https://en.wikipedia.org/wiki/Alpha_21264 https://www.openpa.net/pa-risc_chipsets_zx1.html
