As an educator I would've loved to have this last time I was teaching SQL. 1: No install 2: Ephermal (just reload if you've messed up?) 3: Good syntax highlighting 4: Visual UI to navigate the model Why to pay for it though? That

Actually debugging a PDF parsing issue as we speak and actually started writing a parser (partially to understand the issue, partially as a last resort as the code in the parser I was debugging felt a bit shoddy). The PDF format is frankly

This is the most important part. "...linear transformations between vector spaces." When you understand what that implies you can start reasoning about it visually. The 3 simplest (that you can find in blender or any other 3d prog

Honestly, many math teachers are kinda bad at conveying all that. When everything clicked a few years down the line it all became so simple. Like you mention "linear operation", the word linear doesn't always make intuitive s

Right, but it's not anything that most people will be directly exposed to (quantum tunneling effects in microprocessors might be more relevant but still hard to grasp for people). If water capture in arid environments actually scales w

If it's protecting something then yeah it stinks. In this case people are critical of other things also and want to voice those things for selfish reasons without getting into mud slinging contests with fanatics who are protecting ever

Maybe people are afraid to speak up? I've gotten a fair bit of backlash on my negative complaints about NextJS on Reddit, someone even necro-posting on a months old reply then continuing "debating". I think a somewhat neutral

It doesn't even need to be an error in the "assembler" but could be another part that converts from some internal highlevel IR, also for most cases split ops doesn't matter for register manipulating instructions (that y

I guess those that wrote the preemption were on X86 where this doesn't happen thanks to variable length instructions being able to hold the constant and thus relied on the code-gen to do it atomically, then the ARM port had an automati

Oh wait, looked at the source again, so it's some weird stateful collection thing triggered by the type coercion? By now I'm wishing that it was operator overloading.

Someone building their own probably isn't too afraid of missing out on a webgui or installing something like FreeNAS or whatever is the popular choice these days. I think the NAS market is in for an upheaval due to the markups for fair

And that was the downfall.. 1: Standardization was made by committee lovers and/or architecture astronauts leaving us with overly convoluted (sometimes to fit lacklustre object models in early OO languages) and complex ways of working.

While quantum-tunneling is quite niche I think it's given to demonstrate something with everyday life application (considering the outsized impact of microprocessors on society). This MoF thing is quite damn cool though, advancing mois

Probably written by Swedish persons, we also use -s suffixes in many places but basically never with apostrophes so using them when writing English can be a bit hard to get correct (and vice-versa going back to Swedish it's easy to add

C++ has std::format these days that does a far more sane thing, people are too quick to throw out the baby with the bathwater when it comes to bad things. Some OO is fine, just don't make your architecture or language entirely dependen

Fully agreed, var-arg functions are well established in JS so no need to abuse operators for these kinds of things.

This kind of stuff is why C++ developers has an almost overly allergic reaction to operator overloading.

Yeah, this is some weird "performance" optimizer that half-misuses terminology and complains that using an underlying container is bad for implementing their own basic container. Eh yes, you're implementing your basic contain

Doesn't mean that machines won't be built with other chips for a considerable time. That said, if you're putting something like Erlang on a chip, aren't one likely to want the extra memory (and performance) of a slightly

As nice as WebDAV would've been it's probably a non-starter in many scenarios due to weird limits, like Windows has a default size-limit of 50mb. I'm tinkering on a project where I'd like to project a filesystem from cod

Any interpreter could theoretically do those "marking" things, also JIT's do far more than just "bytecompile" hot loops, _all_ cooperative modern GC's are enabled by JIT semantics for things like read and/

There will always be enthusiasts to take the initial steps, the question is if they have the taste to make it a coherent system that isn't horrible to use. Counted out over N languages, we should see something decent land before long.

I wouldn't be surprised if it did take off, classic Wasm semantics were horrible since you needed a lot of language support to even have simple cludges when referring to DOM objects via indices and extra lifeness checking. WASM-GC will

There's 2 things, 1: JavaScript _interoperability_ , ie same heap but incompatible objects (nobody is doing static JS) 2: Java, Schemes and many other GC derived languages ,etc have more "pure" GC models, C# traded some of it
