There's a similar pattern in rust: fn loop(a: &[u8]) { assert!(a.len >= 20); for x in (0..20) { let y = a[i]; //Do something with y } } Adding the assert bef

I'm fairly sure the ending lines: Hello Mike, Hello Robert, Goodbye Joe. were a reference to the movie. I went to go watch it again after reading this but you beat me to posting the link here ;)

I found the creator's HN account, looks like he planned on making one at some point: https://news.ycombinator.com/threads?id=Technologicart Maybe he'll see this post and finish the video :)

Are you aware that this can be done without elevated privileges using seccomp(2)[0] and ptrace(2)[1] using SECCOMP_RET_TRACE? (or with ptrace alone using PTRACE_SYSEMU) Although the ptrace API can be daunting and I believe it's somewha

For anyone interested in more information, I found the research paper[0] and website for the currency named "Unit-e"[1]. The paper seems to be quite extensive at 168 pages long and covers a lot more than the blockchain design. [0]

It's definitely still happening, however there are workarounds that bypass the driver's checks by changing hypervisor settings. One particularly insidious "feature" is that on the Quadro series of cards, which are ostens

NX does not need to be disabled[1] for the binary thanks to W^X[0]. As long as pages are never mapped as writeable and executable at the same time, you don't lose any protection. [0] https://en.wikipedia.org/wiki/W

I don't think this makes sense, while the C-level exec may have a lot more to lose measured on an absolute scale, the quality of their life will not change significantly following their resignation. However, the janitor potentially has

EDIT: After typing this up I realized big.LITTLE was mentioned and the article and it what OP was referring to but people may find the explanation useful so I'm posting it anyways I'm a little surprised no one else has mentioned t

For anyone (understandably) confused about the attacks and mitigations related to L1TF, I've found the linux kernel documentation on the mitigations[0] to be a great resource. One interesting thing is that to mitigate L1TF hyperthreads

It's interesting to compare this to the idea of the brain having two systems of cognition: a "System 1" process that is automatic and quick to respond, relying on memorized behaviors; and a "System 2" process that i

Just a correction on this, 1 million tons is equal to around 240 million gallons [0], which is roughly the volume of 362 olympic sized swimming pools[1]. [0] http://www.wolframalpha.com/input/?i=1+million+tons+of+water.

This is totally possible and is very similar to how I have my desktop currently setup. Check out this subreddit[0] and this Arch wiki page [1] for a step by step tutorial. The tricky thing is for optimal performance you have to give a guest

Oh, it definitely could be considered as evidence that Github is a better platform for code hosting than gitea, gogs, etc. However I think that the difference is popularity is far more likely to be caused by network effects around Github as

I'd guess that this is more due to the popularity of GitHub among potential contributiors to these projects. I've seen it mentioned many times here on HN that a potential contributor may not want to put in the effort to create an

The author also admits to downloading a fresh restore image from Dell, which I would assume would create a fresh install of Windows without any "tweaks," and then still experiencing the same issue.

I think one of the points that this and some of the other comments may be missing is that this isn't electron with vim keybindings, it's an electron gui for a real (neo)vim process running in the background. All your standard vim

To respond to this and the child comment, since Oni is a wrapper that communicates with an actual neovim process, most (neo)vim plugins should be useable with Oni. I've had great success simply telling Oni to read my existing init.vim
