It's funny. I think a lot of more software-y people just don't see the need for a lot of Framework features. I deal with a lot of hardware (as a hobbyist and a hardware engineer) and I've seen every USB standard connector in

It may appear to work, but it uses a lot more CPU than a decent 10G network card, despite being half the speed. I shudder to think what their 2.5G must've been if this is better.

I feel ya on the PCIe slot. And the on-board NICs are sub-par Realtek garbage, unacceptable both on features and quality. However, you can fit a small SFP+ card inside if you (a) cut out a correctly shaped hole in your case, and (b) turn th

Would a SLG46880 work for you? It has 28 GPIOs, enough LUTs to make a 21-input OR gate, runs off 2.3-5.5V (two VCCIO partitions, but you can tie them together). It costs like a buck in 5k quantities - they used to be much cheaper when you b

I don't know... Two people around me recently switched to Linux because they could not stand how bad Windows 11 got. I did not encourage either of them (I've got my share of frustrations after running a Linux desktop exclusively f

We have GHz femtosecond lasers. It's commercialized! Amplitude Systemes has them for sale! We build time references out of them! You can also make them out of semiconductors. VCSELs and other semiconductor gain media naturally have sho

Oh, fusion has been ready for this sort of application for over 70 years.

3% FWHM for something you could, at one time, buy for under $100 on eBay is very good. A typical scintillator + photomultiplier detector will get you about 6-7% (NaI:Tl scintillator). The Radiacode, which is super cute and all, gets about 7

A few years ago, CZT detectors made by eV Products showed up in quantity on eBay. Pretty much everyone interested in radioactivity seemed to snap one up back then. It took a fairly long time for folks to figure out how to use them well! But

Is this really even a little cursed? It's a perfectly nice device, and in fact has been manufactured as a chip before. Enpirion has made this under the name of EC2650QI 6A Voltage Divider: https://cdrdv2-public.intel.com&#x2

Does KVM hypervisor work? Previous Qualcomm CPUs have locked hypervisor mode behind Qualcomm proprietary blobs, and only allowed HyperV to use it - this was definitely the case for WOS laptops.

I believe the proper term for this kind of "as a one-time gesture of goodwill" is "ex gratia", and is more-or-less a standard form for compensation without admitting liability.

I think a lot of the negativity comes from the odd choice of keyboard layout. You can think of it as a weirdness budget: this is an odd-purposed device, running a specialty distribution of Linux by design. It is not portable despite having

Agreed, and I'm fairly impressed by the GPU effort. That said, it did take a very long time, even with the demonstrably extreme amount of excitement from the Linux community (Linus himself was thrilled to use a Macbook). What do you do

I mean, part of that is the difference between how easy it is to build a platform in Linux vs how hard it is to get into the tree. This is actually, in my mind, a major change in the Linux development process. Nobody expected Intel to provi

I wanted to give a quick explanation of the odd and off-hand "lightbulb" comment in the article. Why would an oscillator need a lightbulb? Especially since the article does not get into the weeds of building oscillators that would

The issue with the lengthy deliberative process is that it provides multiple opportunities for motivated, but ultimately damaging to the public, operators to intervene. In this case, I present to you the Americans for Common Cents: https:&

Unfortunately, the symmetry provided by higher levels of your software stack is not always reflected by the lower levels. This causes your symmetry to be created as an abstraction. (Subroutines are more efficient to implement than co-routin

I'd expect the loss coefficient (tan d) to be terrible . Cellulosics hold onto water quite well. You will not have a good time pushing anything high-speed through this kind of board. I would say the only practical application would be

It rises and falls. It's right in the title! Perhaps it has little jets, or maybe a particularly specialized form of antigravity.
