Many IC manufacturers treat their "API" (hardware registers) as proprietary IP, require an NDA from the driver developers before releasing the development guide, and require an agreement not to publish the driver. I'm mostly

And as Feds demand skeleton keys to buildings, prepare for the death of cylinder locks? Prepare for a change in how we use it, not for its death.

I don't really understand your question here. NVM is non-volatile memory. Stick a filesystem on it and it's still non-volatile memory. Do you mean they were writing configuration files directly to a known address in Flash instea

If the NSA actually pays any consideration to how the value of their data helps find "terrorists"/criminals, iTunes data is probably not particularly valuable.

Very late response: this comment thread was a general discussion about privacy, it wasn't specifically about the article. And a maaku on HN could easily be this maaku on github from California: https://github.com/maaku

I don't know about the EU, but in the U.S. your statement is simply not true. Somebody absolutely can follow you around taking photos or videos, as long as you are in a public space and they can come up with any non-malicious excuse (

Yes, although I make fun of LLVM for the non-optimal code, I really doubt anyone would consider them 'bugs' -- and I did not. They aren't bugs, they are just optimizations that we haven't found a good way to automatical

It's not the extra 1000 instructions of this call that is concerning. It's the extra 1000 instructions per thing-that-would-have-just-been-a-null-check summed over every running process on your machine if this actually took off a

This is the response I was looking for. We keep making computers 2x faster, and then making software architecture 4x more wasteful (given, it's also 20x faster dev time). "if (ptr == NULL)" is usually two instructions and an

I'm always amazed by the strange assembly generated by modern compilers. LLVM will auto-vectorize a routine into this awesome NEON SIMD masterpiece... and then throw in a bunch of completely redundant stack loads/stores and refus

It usually is inline assembly, but you write it in C first and copy the disassembly as a starting point. We do this in the embedded world a lot because we're constantly switching architectures, and nobody memorizes the instruction s

Everybody I know who writes assembly language in practice now, self included, prototypes most of it in C first -- why not take the huge headstart from the compiler generated ASM? And I usually prototype the C in Python first :D

I moved here from the U.S. The process was fairly fast and simple, and as soon as you have a work permit you get all of the social benefits. It only takes 5 years to get citizenship, too. It's supposed to be fairly easy to bring a sp

I moved to Sweden from the U.S. about 3 months ago, and it was a very easy process (I already had a job lined up here). The hardest part is international interviews: they really want you to interview in person, and they really don't wa

Sweden has a pretty easy immigration path, is fairly friendly to immigrants, most natives speak English, and has a large tech community with not enough local talent.

I don't think these 'quick intro to bitwise operations' and/or 'cool bitwise operation tricks' articles ever go into enough detail to be safe. Bitwise operations can be _extremely_ useful, but it's surpris

Except this library doesn't have proper memory protection, and node.js has system access so it could just use GnuPG and be a lot more secure (and almost certainly faster, too).

by mrmekon 13y ago
This is not a PGP library. It's a wrapper around gpgme, which in turn is a wrapper around gnupg. node-gpg just exposes the GnuPG command line as javascript functions.

If anybody uses this, please keep in mind the differences in security possibilities between native C code and Javascript. Both this and GnuPG encrypt and decrypt data with PGP keys. GnuPG, however, does this securely , in many, many sense
