Never? There definitely was a double-width feature on those printers, as demonstrated in the manual: https://www.apple.asimov.net/documentation/hardware/printers...

How about a situation where the inner Optional<T> is acquired from another system or database, and the outer Optional<Optional<T>> is a local cache of the value. If the outer Optional is null, then you need to query the ot

Did you ever try doing your programming exercises in AmigaBASIC instead? It was also made by Microsoft, so it should have been quite compatible with GW-BASIC.

You can put pointers inside data structures on the heap, similarly to what you would do in C. The functions that process those data structures only need local variables (or stack slots) for a few pointers, and with those pointers they can f

The branch-and-bound algorithm does provide a proven optimal solution. This does not mean that P=NP because the size of the proof is not bounded by a polynomial in the input size, and neither is the algorithm runtime. Also, Euclidean TSP is

You could still save the branch-and-bound tree, the LP problems solved at the tree nodes, the derivations of the LP cutting planes, and the LP solutions that together constitute the proof. Then you could in principle create an independent v

Commercial Linux distributions like Red Hat, Suse and Canonical stake their reputation on compiling a trustworthy collection of open source software, in exchange for money. Unfortunately they disclaim any legal responsibility, but at least

Thanks for the reference, looks interesting.

Wow, thanks. As always, the best way to learn more on the internet is to be confidently and totally wrong!

The Burroughs-Wheeler transform has been described as a unique algorithm idea in that there are no non-trivial variations or related algorithms, unlike more conventional compression algorithms, which can be tweaked and improved in so many w

Based on the presented multi-core benchmarks, the single-core performance is 40-50% of a single M2 Ultra core: 40% on the HPL Linpack benchmark, and 50% on Cinebench. That is compared to the average M2 Ultra core, counting both the fast &qu

Based on a quick googling, apparently the original paper is "One kitchen is all you need" by Sister Eudocia, Isabelle DeVerneil, and Jane Hildebrandt, published in Modern Hospital vol. 79 issue 3, pages 120-122, 1952. https:&#x2F

The Nature paper refers to potential applications in spintronics. I'm guessing they mean some kind of improvements to MRAM devices ( https://en.wikipedia.org/wiki/Magnetoresistive_RAM ), which can be faster than con

An important point here is that the integral of the likelihood function over different parameter values is not constrained to be 1. This is why a likelihood is not a probability or a probability density, but its own thing. The confusing bit

This is also why it is surprisingly easy to break your dependencies when installing lots of stuff in pip: sooner or later you're going to end up with some dependency-of-dependency incompatible with a dependency. The practical solution

C++ templates do have the advantage that they can dispatch on their argument types. Lisp macros are expanded at a purely syntactic level, well before the compiler attempts to do any type deduction, and you cannot provide different macro exp

OEMs like it when it's them buying the cheap RAM chips and getting the juicy profits from huge mark-ups, not so much when they have to split the pie with Intel. As long as Intel cannot offer integrated RAM at price equivalent to extern

A Zen 5 core has four parallel AVX-512 execution units, so it should be able to execute 128 16-bit operations in parallel, or over 24k on 192 cores. However I think the 192-core processors use the compact variant core Zen 5c, and I'm n

Why would they not share that data as a justification for this decision to return to office for five days a week? That would give investors a reason to believe that Amazon productivity and share value will increase soon.

Yes, the so-called "network byte order". Now that big-endian has lost on all other fronts, it is time to switch to little-endian in all future network protocols. We could call it the krowten byte order.

If the data is not in cache, it takes quite a while longer from the time the CPU core issues a load instruction for the results to get back to the next instruction. The CPU core has to first try L1 and L2, do a TLB lookup to convert a virtu

At a basic level, anything with a working set on the order of 360 MB should benefit from 360 MB of combined L3 with a worst-case latency of 11.5 ns, regardless of which parts end up in which L2 slice (and the cache allocation heuristics des

Apple bought P.A. Semi in 2008 and put them to work on ARM cores right away. On the other hand, there were noises about the A-series being faster than x86 already at the time of Apple A13 in 2019. https://en.wikipedia.org/wi

Good point. It makes me wonder if modern out-of-order processors can skip performing unused computations altogether, if their result registers are overwritten by other data later (in program order).

Now that they are transitioning the desktop version of Outlook into an Electron-like webview, I suppose showing HTML directly in the webview is out of the question, and they must be using the Javascript version of Word to render HTML...
