The Google problem is "normal", in my experience. If you're trying to access an inactive account, Google will almost always insist on a second factor (verification via secondary email account, phone number, etc). If you haven

I suspect it's some sort of color ASCII art format. Character/attribute pairs with probably some control information. That explains why the other files have readable text.

Linux is used in many more contexts than OpenBSD. Moreover, unlike OpenBSD, Linux explicitly promises not to break userspace on new releases. So yeah, the Linux devs are more hesitant about anything that might be a user-visible behavior cha

12-15 women working for 3 months is close to 4 person-years of work. That's higher than the numbers in Fenrisulfr's quote.

How does that book compare to the third edition of Ousterhout's _Tcl and the Tk Toolkit_? (other than that Ousterhout also covers Tk, obviously)

How much of this is driven by modern C++ style? I always assumed optimizers needed to become much more aggressive because template-heavy code results in convoluted IR with tons of unreachable code. And UB-based reasoning is the most effecti

The article doesn't make this explicit, but this game is just using LZEXE. This was an executable file compressor that was very widely used in the early 90s. An early project by Fabrice Bellard!

Suppose you protect a piece of data with a checksum. The data gets corrupted and the checksum no longer matches. That's a detectable error. But if you're unlucky, the checksum of the corrupted data matches the original checksum. T
