Rust is awesome. It's likely a better fit than Go for applications like this, as it has more predictable performance[1], and more control over the scheduler (as you have to roll one yourself). I attempted an implementation of Tor in Ru

There are separate reader/writer goroutines, I don't think splitting them up further would've helped much. The problem is that all connections may end up needing something from all other connections, and as soon as one of the

Ha, I see how it can sound like that :-) Yes, it broke the speed record: a multithreaded application outperformed the singlethreaded version. But I wasn't happy with the result. It consumed an order of magnitude more memory, and gc tim

Hi. I wrote the post, happy to answer questions. * yes, more modern versions of Go would likely mitigate some of the memory pain * yes, crypto/tls is fast now * no, crypto/tls still has insufficient functionality for implementing

This is awkward... When newzbin shut down, I was without a NZB provider for a week. Then 2 days ago I paid for my membership at NZBMatrix. And now it's gone?

Non-native English speaker here, I volunteer at several companies to translate their interfaces. Almost all people can read basic English (especially those who access Github), so translating the Github interface seems rather pointless to

Transaction fees are a 'gift' from the person doing the transaction to the person that's processing the transaction. Processing transactions is done in blocks, and the process is called 'mining' because for every processed block, the person

For the record, distributing Python scripts doesn't have to mean distributing the source: it's possible to just execute the compiled .pyc files, which are harder to crack than (for example) Java's .class files. Also, since xor is just a CPU

I've been using Windows 8 since roughly two weeks before its launch, and I agree with most of the article. In fact, I just realized that I never use a single "Modern UI" app for the simple reason that they force my entire screen (2560x1440,

Happy to see that a big site is finally starting to support WebM. I hope that they've chosen to not support h264, because of its proprietary nature?

You don't have to get the base port on each try, you can just re-use the previous result. I achieved this by simply storing them on the global scope and only keeping the "last" and "before last" port numbers. https://gist.github.com/38c043

https://gist.github.com/38c0430b5084f8442858 You only need 1 call per possible number for each chunk, yes. But since the numbers are random between 0 to 999, that averages to 500 requests per chunk. Additionally, you don't have to do any

Yes it was. But you could optimize the brute forcing so much that you needed only ~2400 calls to the API to crack a 12 digit password.

You should try to extract the ones from iOS 5. They're hardcoded in Twitter.framework (simulator versions as well) and can be extracted with the simple "strings" tool. I'm not going to post them here though.

I'd argue that this is actually good for security in that keyloggers are indeed useless. There's one downside: if the bank gets hacked, you lose your password. But seriously, let's face it, that's not an issue because nobody uses the same p
