Right now, there are approximately five languages that are presumed to be acceptable for core applications in the base system: C, C++, Shell (which probably means specifically bash), Perl, and Python. The most recent language to be added to

This reminds me that at some point I should write up my exploration of the x86 encoding scheme, because a lot of the traditional explanations tend to be overly focused on how the 8086 would have decoded instructions, which isn't exactl

The Øresund Bridge is a combined road-rail bridge. (As an interesting aside, the Swedish railroad system drives on the left, while the Danish one drives on the right, so the trains have to cross to the other side after crossing the strait.)

It is definitely way too easy to accidentally confuse "x is true" and "x is proven to be true" on topics of undecidability, and this is one of those times where the answer is in fact obvious, but it takes you 15 minutes

With a strong Anti-SLAPP statute, the person who files the lawsuit is on the hook for the defendant's legal fees, which would (in theory) let the defendant hire an attorney on contigency fees. Of course, one of the other issues is ther

Look, I work on compilers, and I have no idea what you're even trying to refer with "planned obsolescence" here. And 5/10 years is a very short time in compiler development planning! Prototypeless-functions in C were d

It's been a long time since I last stared at DER, but my recollection was for the ASN.1 schema I was decoding, basically all of the tags ended up not using the universal tag information, so you just had to know what the type was suppos

I'm hardly a connoisseur of DER implementations, but my understanding is that there are two main problems with DER. The first is that the format isn't really parseable without using a schema, unlike (say) XML or JSON. This means y

I'm extremely uncertain of my history here, but my recollection is that SSA wasn't seen as practical until the development of the dominance frontier algorithm for inserting phi nodes, which seems to be 1991.

SSA isn't about saying mutation is evil. It's about trivializing chasing down def-use rules. In the Dragon Book, essentially the first two dataflow analyses introduced are "reaching definitions" and "live variables&
