ZLUDA is still alive. AMD sponsored it and the project was briefly halted during a dispute with them, but it’s been making steady progress. It doesn’t really make sense for AMD themselves or most use cases, though; any compatibility shim ju

The CUDA runtime coming with a gazillion reasonably decent kernels (DNN, BLAS, CUTLASS) and a concurrency system (NCCL) is a big deal; especially in the “early days” very few researchers or development runtimes were even writing their own k

Certainly not at these frequencies and corresponding high capacitance values; getting 22nF out of a PCB even with ECM would require quite a large surface area and at 220GHz you can't have that since your wavelength is so short; you&#x2

A sizable percentage of datacenters use open loop water spray towers, but the alternative, forced air exchange (ie add more giant fans) uses more electricity. It’s fairly complex to quantify which is “better” or “worse” but there exist data

That's not how this works, at all. Visual approach is a specific IFR procedure. It's basically designed to expedite and simplify the landing process in situations where the pilot can see the airport and traffic allows - instead of

It's "just" a restructuring; the previous setup was a really bizarre financial product where Citizens Bank gave you a 24-month 0% personal loan to buy an iPhone, but Apple would also buy your phone and loan out and sell you a

My experience has been that Qualcomm mobile phone chipsets don’t run Android on the modem side, but that standalone (ie laptop / USB / router) ones like this Quectel part sometimes do, in order to provide the userland components t

I don't think I'm really conflating anything, and I don't agree with your thesis even though I agree with individual points. 1) Yes, unless you add abstraction at the ABI/ISA level in hardware or microcode, which then de

The myth I was referring to was the overarching theme that “VLIW would have been practical if only a better compiler existed,” which I don’t believe to be true for modern or Itanium-contemporary general purpose computing patterns.

These worked well for “known” intra-task pointer aliasing situations, but if you don’t know what will be in cache due to preemption of any kind, you still don’t know how many cycles the speculative loads will take, so you get the same stall

No (sorry, I post this every time the Mythical Compiler Myth reappears), the problem with VLIW is that it fundamentally doesn’t work for anything with unpredictable memory access patterns, and modern general purpose computing has moved almo

This is a very good text and regarded as one of the greats for a reason, but it glosses over a lot of lower concepts (like OFDM, which if I recall occupies only a single short chapter) and focuses very heavily on MIMO. Proakis and Salehi (&

Zoom were a very longstanding modem company who expanded into cable and routers and licensed the Motorola brand in 2016.

Vendor wise, these were never really made by a “Motorola” -this is a Zoom router (thus the domain) that used the Motorola name under license. The “old” Motorola router division Motorola Home got sold to Arris _without_ the brand name in 201

It’s a completely different backend model; as far as I know alipay works just like PayPal where transactions are fully “internal” - the buyer pays Ant Group and the seller cashes out at a later date. UPI is a real inter-organization payment

Right, there are two problems there: * Pilots are very concerned about life and safety and are heavily exposed to drone “incident” related anecdotes, so they err far on the side of caution with drone sightings. Which is to say a very low pe

Most major airports will already have a counter-UAS system, it's a huge industry. One big issue with radar is that it has the same problem pilots and human observers do: it struggles to distinguish drones from anything else in the sky

This is weird to me too, especially to say in the present tense in 2026. I think I get the point about "Rust culture" (although it's too vague to agree or disagree with, probably on purpose). But in 2026, Rust is fully a comm

It’s a huge problem. The most common approach to address it is called smearing; the duration of each second for a 24 hour period ahead of the “leap” is adjusted. For strict ordering systems this works as each device maintains time sync with
