That's rather surpising, coming from someone proficient in C. Perhaps you only need to discover the close connection between C and assembly. The layer between them is really razor thin — by learning a few C idioms (function prologue&#x

Having taken up x86 assembly coding again after many, many years (last time was on a 486, really), I find 64-bit assembly much easier to get started with compared to 32-bit: Simpler calling convention (on UNIX, at least), no segments, mor

Unless I misunderstand you, I thought the exact opposite was true: The separation of source from binaries is what made UNIX a success. When C was designed, it allowed one to take the source from one machine to another, disregarding the un

Note that I don't know anything about SGX, but skimming very briefly through the first part of the below slides [1], it may look like it's just the ability to create — at runtime — special memory regions that are unreadable ou

You don't need to go to such complicated lengths. Just perform enough tests (as in, a statistically large enough amount) and a distribution will form. That also captures the variability of real world network effects.

While true for large demos, the 4kb — perhaps even 64kb? — are still written very much by hand.

Haha, thanks for spotting that! It should lead to the link in the above comment of course.

The next step is smooth coloring. I've written a post explaining it here: https://csl.name/post/mandelbrot-rendering/ The js code can be tested on https://csl.name/mandelbrot

FWIW, I implemented some BB code in Python and made some pretty neat plots: https://github.com/cslarsen/busy-beaver Of course I cheat by knowing S(n).

I find that pointlessly pedantic. By the same measure, languages that don't offer bignums don't offer integers. Even Lisps need to implement closures in one way or another, and you may be surprised to see how they actually do it.

Well, as long as the functions are short and the name is descriptive, I always use short names when the meaning is clear. For example strlower, you don't need more than `s` as the parameter name. It will probably be short, so using `le

But that would only be possible from the same process space, right? So only applicable for plugins etc.? What I'd like to see is hotpatching the function for another process, but I guess that's very hard to do with ASLR. Probably

I google for "define:word" to check for spelling, but a thesaurus is usually available in the drop down menu. Then I search words with similar meaning to find the word on the tip of my tongue.

Thanks. It's definitely a lot of fun. And, as you can see, some things are not hard at all to detect. In fact, I was surprised how little knowledge you need to be able to flick through genome wide association studies (GWAS) and cas

Nice. But does it handle extended jumps? I know this is a problem for at least the Byteplay module.

I wonder if assembler is going to make a come back :). I'm certainly seeing a lot of cool projects that make assembly more accessible, not to mention a lot of good guides on the web. As for myself, I've recently made Python ctyp

Looks pretty neat, but the demo account is too limited. For instance, it found a problem with my other comment here, but wouldn't tell what (of course, I have to pay up 30 bucks to see what it found). And, I guess it's web-only, w

Thanks for the kind comment! I'm Norwegian, and I do consider English as one of my primary languages --- but it's not my native language, so it's easy to write something that doesn't sound right to others, not to menti

Exactly! The top-level is actually special in many circumstances. Some people have suggested removing call/cc from Scheme. I don't know if they want to put delimited continuations in its stead. See http://okmij.org&#x2F

Not by default, but I've seen some schemes offer serialization of continuations, for example http://wiki.call-cc.org/eggref/4/suspension

It says it's just setjmp/longjmp, but later on expands on that, saying you can jump not only up the stack, but down and sideways too (#1). I think the best explanation (mentioned in the article) is that you take a copy of the en
