The generalized form of this would take arbitrary cleanup actions, not just file deletions, and would look a lot like atexit(); In fact, one could put a SIGABORT handler in that would (a) deregister itself and (b) call exit() to run atexit

Automobile franchisees (car dealers) skew overwhelmingly conservative. Draw your own conclusions.

At the time he said it, and about the time of the decision he was making, what you say about the TCL ecosystem was not necessarily true. I was using TCL/TK in '95, and it was clunky then. I have the same misgivings about LUA now,

ASN.1/BER is a pain in the ass. I'd rather gzip json. Or poke chopsticks in my eyes. (creds: http://tools.ietf.org/html/rfc1697 )

Shared libraries and DLL's came into being before the software patent flood opened, probably by 10 years or so.

The Economist rather notably omitted the seeds of the current state sowed in the Sykes Picot agreement, which made a hash of things just as the old local power structure was in collapse. Rather than create a stable start for the region as

Common CRT capability is also how we got the 320x240 (bad TVs) and 640x480 (better TVs) resolutions.

by dbrower 12y ago
Coding forms? No. Commonly available CRTs were designed for 525 line alternate frame TV, which really give about 262 lines of resolution. That gives a just-barely legible 10 dots for a text line on a 24 line display. -dB

There's nothing that requires most auto id keys to be monotonically sequential, which is the bottleneck when distributed. If uniqueness is all that's required, blocks of id's can be handed to different hosts and replenished

I take it to imply the 'system' they are programming is the distributed/concurrent complex they are running. To other people, 'system' is below that, and this is application programming, or "middleware" I

Thanks, I appreciate the discussion.

Yes, fsync typically chews a boatload of CPU running down the pages in the cache to see what pages need to be written, then all the i/o path to enqueue the writes.

Boo hoo. If that's what it takes to perform, then it should be done. Ingres had it in the 90's. A win for OLTP, sometimes a lose for DSS queries with scans.

The things that want sync don't usually want a promise for future time, they want positive ack the data is on the storage. So a deadline approach is pointless. Async w/O_DIRECT is the correct approach, despite the complexity. T

fsync has been broken since it was introduced in BSD4.x. It's never worked well, usually flushing the whole machine cache in one huge batch of i/o. I'm told current versions on Linux will restrict it to the one open file,

Thanks, I appreciate the answer, and am trying to be more informed. On transaction count, I think "we" /may/ care about transaction count, if the majority of transactions are shams or gaming the trading system. To the e

I think a reasonable question is why we consider /more/ transactions a good thing, if a large fraction of them are for holding periods in small number of seconds. I think I am questioning the fifo paradigm, which creates these arb

Can someone explain why any of these is a bad idea? (a) completed transaction tax; (b) regulatory fee on offers/cancellations; (c) insertion of random delays into offers/cancellations; All could increase friction and reduce the sp

Jeez, it would be nice if someone, somewhere, would define GAME_JAM for those of us out of that bubble.

Go ahead and poke the beast. You'll be hard pressed to find anyone who knows more about the rot-gut work of displaying 3d spaces in realtime on cheap hardware.

"It seems they often assert controversial opinions as accepted truth." This would be my main content complaint as well. But what I really find objectionable is the non-student subscription price, > $200 for a renewal.

MJ "leans in" pretty hard too. The recent story on Elon Musk tries very hard to be a hatchet job, and comes off badly because of the forced angle.

I take this as an overgeneralization from the bugs the original author runs into most often, which may be domain specific -- overflow in signal processing being endemic to the problem. In many other cases, one of the common bugs is unexpect
