It seems like they tried, but no blockchain expert would go near it because it was so clearly a Ponzi-type scheme. Just look at the website: http://web.archive.org/web/20150302021347/http://www.onecoin...

To be clearer, this is a retrospective of the DEF CON CTF, not the entire conference. I enjoyed the writeup of the Pew Pew challenge. That sort of challenge is exactly what high-level CTFs need, making them more fun and visual and accessibl

When using Tor it is important to be indistinguishable from other Tor users. If you can be fingerprinted by user agent, screen size, fonts, add-ons, or numerous other indicators, then the anonymity set of your browsing behaviour essentially

I found a benchmark that suggests the performance gap between a pipe and input redirection is insignificant for most workloads, but there would indeed start to be a difference for the exact case discussed here (grepping a large file): http

It annoys me whenever somebody brings this up. People do this because it's easier to modify commands at the end of your prompt than near the beginning. Especially in this case, where the grandparent wants to quickly switch between benc

Another reminder that the advice doled out to teens to "follow your passion" when selecting a major and a future career, is rather irresponsible. Cal Newport's "So Good They Can't Ignore You" is a great read on

I've used Z3 a lot for CTF challenges, but in my day-to-day work have never encountered any problems that it would be useful for. I'm interested to know how people have used it in the course of their work?

Of all the Voynich theories, I find those suggesting it was produced through a mechanistic method to be most persuasive. Several statistical properties of the words just don't match up with any natural languages, and there is a large a

I just dug around a bit to find the likely source of the "crypto magic pixie dust" quote, and I think it's Gary McGraw. He uses that phrase a lot, and a search of "crypto fairy dust" in Google Books brings up books

This is a great introduction to fuzzing, I love the section about minimising the corpus of fuzzed inputs and turning that into a test suite. That's something that should be done with all parsing software!

I'm disappointed that the article didn't explore another perspective on Milton's Satan, which is that the "Devil's party" is deliberately cast as more appealing than the virtuous one. Milton's point is tha

Managed to get over 120. Because the red terminator can't cross the edges, but you can, the key is to use the edges as much as possible and to avoid going through the center unless you are lined up to get the food.

It's good to hear that Thunderbird is getting more resources. One UI bug that I didn't see mentioned in the post though, and that shouldn't exist in 2019, is that Thunderbird loses the scroll position of a tab when changing t

I also had a similar idea a few years ago for a CTF challenge, coming at it from a "modern Caesar cipher" perspective: https://laurencetennant.com/unicode-shift-cipher Also a crude "modern Bacon cipher"

The article doesn't go into much detail nor even explore all the possible etymologies. My copy of the Oxford English Dictionary suggests that the meaning of 'quiz' may be associated with the word 'inquisitive'. Anot

I think the piece was aiming for maximum irony. Also note: "In a 2001 study two scholars in Canada (LINK) showed that comprehension declines as the number of hyperlinks in a document increases."

I was more confused by the parameter being named 'num' before having the String function called on it and its length taken - when in fact 'num' should be a binary string when it's passed into the function. But maybe

All due respect to Rob Pike, but I think David Batley nails it in his response: > tl;dr: they replaced a cryptic, undocumented implementation, which starts an entire bash shell just so it can exit, and replaced it by a fast ELF binary,

Because that's not how array initialisation works in C. The specified indices are initialised with the provided values, and the missing elements are always initialised to 0. See for instance section 6.7.9 of the C99 standard. Perhaps y
