No mention of runtypes which looks pretty similar? https://github.com/pelotom/runtypes

ZFS, Btrfs, etc. essentially provide that with filesystem snapshots; LVM snapshots probably also works for that. Not sure whether any easy tooling around it exists though.

I read 'Modem' instead of 'Modern' and it still made sense.

BeagleBones are awesome for these kinds of things. They are very similar to RPis but in addition to the ARM core they have two embedded hard real-time capable CPUs (dubbed PRUs) that run at 200 MHz.

This is fun in theory, but doesn't really give you a lot in practice. A few random points: * On many server systems swap is already disabled today (for availability reasons), so you don't really win anything. (Although what you&#x

Nice project! Unfortunately, as with most interpreters written in C, afl finds segfaulting bugs in a few seconds. In your case at least empty variable substitutions are broken. E.g., entering $ foo will crash.

It looks like Kelsey didn't write a lot of assembly before. There are quite a few things you either wouldn't do -- like `cld` for no reason -- or most people (and compilers) would do otherwise -- e.g., `xor ebx, ebx` instead of `m

Lesson learned: blacklists are catastrophic for security purposes, because you will always miss something. Even if you didn't miss anything, the next kernel release will just add something new that I can exploit.

Sure, but it's not any better than the Android FDE, and thus kind of defeating the point of the article. If everyone just uses the default setting, then iOS's encryption is theoretically and architecturally better, but it won&#x27

Given that app developers need to actively use those iOS features, the obvious question is: How much of my app data is actually encrypted that way? It's much harder to get these things right (e.g. you want your fancy sync and notificat

LargeCorp foo division buys BigCorp's foo division in order to disrupt the foo business? That seems... unlikely.

Whenever I mention that I don't use compilers I tend to get strange looks from people who cannot imagine writing assembly with using a C or Fortran compiler. And so I have to defend my choice and explain why, over and over. Some people

Yes. As one of my professors used to say: Using "quite obviously" in non-fiction is quite obviously wrong in most cases.

This actually exists in some countries. E.g. in Europe there are (were?) several companies selling modem/ISDN+satellite bundles. All the upstream and parts of the downstream would travel through land-line while larger downloads would b

Agreed. This shouldn't be an issue for anyone using cloud services -- or any computer really. Except for some super duper redundant mainframes maybe, you should always be able to deal with losing a component not matter what it is. If y

The cool thing about the address calculation is that there is a LEA instruction (load effective address), which gives you the resulting address. I.e. instead of actually loading the value from the calculated address in memory, it gives you

I would argue that copying more bytes (as demonstrated) is correct behaviour: (1.) The function is supposed to append a string to another, not paste a byte range into another one, leaving extra bytes at the end untouched. Thus the functio
