I'm thinking that this would be a great device to hand over to family members for when they need help with their computer. Ask them to plug them in & log-in remotely: may be easier than starting RustDesk, and can help with bios &am

I'd be curious to know the compiler used by the Geekbench version they tested. MSVC2019+ now include "volatile metadata" to the output executables to make emulation on ARM faster[0][1], though it seems to be off by default si

Honestly, this whole KVM thread is a bit confusing to me. I've always equated KVM with keyboard/video/mouse switches: enabling multiple computers to be controlled by the same I/O devices. Nowadays I just use a multi-sour

I tried that a few years ago. The result was worse than swapping. The kernel really tries its best not to kill anything, and you end up with "thrashing" again, where code pages (shared objects, executables, mmaped files) are evict

Great build! I am certainly taking mental notes for when/if I get my own house one day. The biggest change compared to a regular house is putting the computers in a server room, and this can probably be retrofitted into almost any hous

You are buying a copy though, and would be expected to have the right to resell it. So digital stores go out of their way to "license" the copyrighted work instead of selling you a copy. I have been thinking about this lately, and

Yes, this could have been a 5-sentence PSA. I found the article hard to read, with comparatively little content for the length.

Probably not with DIMM modules, as longer traces mean higher latency (speed of light is ~30 cm in 1ns). GDDR typically uses larger buses (more wires) for higher bandwidth, even more so for HBM, so DIMM would be hard. Maybe CAMM would be up

I think it's generally OK if you leave the shielding unconnected at one end (good practice anyway to avoid ground loops). There is an electrically-insulating transformer in the connector (nothing that would resist a lightning strike, o

UV can be built (or downloaded) as a single optionally statically linked with the libc executable file, with no other dependencies. That makes it very easy to distribute on weird systems.

Oh, I had no idea you could perform such a "broadcast" ping on link-local addresses. Now, that is a nice trick that will save me some typing between computers. mDNS / Avahi is also great if the machine advertises itself: ju

Just a token fee like $5 would discourage spamming claims, though it does make fighting against re-uploads of the same content harder (the power balance isn't too bad for the play store where there is an entry fee for publishers as wel

AFAIK (at least it worked like that some 10 years ago) the captive portal just intercepts the HTTP page load and inserts its own content (most often a 302). So it just has to be a http web page. Firefox uses http://detectportal.f

I once forgot my phone in a French airport (Lyon). Back then I had a "bulky" (hardened, like the crosscall brand) phone. I had trouble finding it in their system as they logged it as having a phone case. I initially put up a reque

The kit I bought 10 months ago had the issue. Luckily I was only unable to read some chips, and did not fry anything. Definitely check it before using it.

Please make sure you fix the 3.3 V output if you get that device. Most revisions have a PCB layout issue that will output 5V even in 3.3 V, which has bricked stuff before. There are many ways to fix it, one trace cut and one jumper is how I

I read trough the planned improvements a while ago, and came to the conclusion that most would be mostly useful in ultra crowded environments such as stadiums, etc, so not very useful for a consumer. Would you agree? Roaming improvements ar

AFAIK you can't usually replace CPU microcode, as it is signed. Seizing it here, in RW memory, really begs to toy with it: add instructions, edit them. Could you teach your CPU to understand RISC-V? This is just one random idea. But al

Some phones do too, it depends on their power management integrated circuit (PMIC) and driver. Though it's always better to physically disconnect the battery when not in use, as there is always a trickle current otherwise (most "s

Yeah, I'm dubious of the "3x wafers" claim, but I heard "3x wafer capacity", which sounds more logical. More steps per wafer (for TSVs) -> more time spent in the fan per wafer & machines busy with HBM wafer -

Hmm, I have a mouse and trackballs from ploopy, they run QMK, so why was a new project needed? What is the added value? To me, the missing feature in the QMK ecosystem is a devices too device communication channel. For now there is only c

I almost wrote the same comment — the first part, anyways. In theory, it should be feasible to provide a "shim" to bridge the API gap between Linux and Windows internal APIs. The catch here is that Linux is a moving target. AMDGPU

One very nice use case that I haven't seen anyone else talk about is touchscreens. I have assigned my touchscreen to be in a separate seat. This allows me to interact with apps without moving my cursor or changing my window focus. For

It's possible with wayland seats, if the compositor supports it. I've used sway this way. Assign M+K A to seat A and M+K B to seat B. I only wish I could change the focused window decoration depending on the seat (say: one blue se

How do they handle the signature requirement for the VBIOS? I could perform such a mod, but the requirement for a signed VBIOS puts me off. What if timings are wrong, such as with this attempt: https://www.computerbase.de/fo

Regional keyboards are a mess for coding. I'm much happier with a qmk-enabled keyboard where I remap keys in hardware. For instance, on a French keyboard: - easy: " ' , : * ! - _ = ( ) - harder (shift): numbers . µ ? / ℅

Sure! I ordered the necessary part years ago, but didn't get around to do it yet. Having someone else interested may finally motivate me. Please leave some contact info on your HN profile (or use mine), so that I can let you know.

Interesting project! I am relatively skilled at FPS with a mouse, but would like to improve with my trackball (so that I don't have to change my setup when playing an FPS). This could cone in handy, though I imagine that there aren&#x2

I don't have the time to provide such a detailed answer, but there are a few options. At least on Sway (and I imagine other wlroots-based compositors) it's very easy to do: create a virtual output and start a VNC server attached t
