TLB is only an indirect cause. This is because kernel scheduler preempts processes fairly infrequently (100 or 1000hz, or dynamic, but still capped to a small number). Scheduling q…

HTTP2 is all about "tcp-inside-tcp" states. https://github.com/golang/net/blob/master/http2/http2.go#L81 Wherever possible, they do the sensible thing - just goroutines for each fl…

What do you mean "accidentaly"? You either have the file pinned, or not. If its not pinned, you're not seeding anything. If it's pinned, you're liable same as with BT.

> IPFS feels closest to it as of now. I'm rather skeptic. IMO, IPFS is just overengineered bittorrent. At the lowest layer, the semantics are the same, except with really bad ideas…

GIT would come closest. Note that while it's not common now (aside from some first canaries, like scuttlebutt), GIT works perfectly fine as a P2P opennet. You are much less trapped…

All pubs on the wiki are indeed overloaded. Interestingly if one sets up their own, the other pubs eventually sync with it, only the desktop client seems to be unhappy with laggy p…

If you want a "modern web" example, nntpchan - despite the name, its not related to usenet directly, only uses the same method of federated pub/sub replication.

The answer is - it's sorta comparing apples and oranges - libraries, or general C++ inlining cruft can inflate the binary size a lot indeed. A much fairer comparison is to compare …

I'm posting this from chropera as we speak, and I used presto for a decade before that. While your points are spot on, there's one thing about Presto - performance, or more specifi…

Love how the algorithm is simple compared to iDCT based ones, very good job! > No text at all Or indeed anything which poorly maps to gradients. For this I'm thinking about instead…

> A fully concurrent GC is impossible That's a common misconception, of course mutability gc barriers can be made atomic. But it comes at significant synchronization cost, plus usi…

Current channels implementation uses fibers, ie everything runs on single thread and only stack is switched. There is no GIL. If you want true multithreading, simply use pthreads l…

Indeed it's becoming quite promising (using crystal already for few pet scripts which were too slow even for rubinius). Where it's most lacking at the moment is gc - it uses stop-w…

While the efforts of Matasano to make wargaming cool and hip again certainly is commendable, I think HR drones of the world also appreciate a game of "pretend to be sociable teampl…

Spender did excellent write-up about how it exactly works: http://www.reddit.com/r/netsec/comments/1eb9iw/sdfucksheepor...

Try dmesg.

You're correct. Bug is in 2.6.37-3.8.8, fixed in 3.8.9. http://lxr.linux.no/linux+v3.8.9/kernel/events/core.c#L5331

Not that I know of, hence 0day.

Either your kernel is patched, or the exploit does not work on your system. It certainly fails without -O2, glance over the code indicates horrible reliance on various UB on how gc…

Than you so much for this. You actually implemented Haskell/Caml for us, mere mortals, and as close to bare metal as possible. Bravo!
