Native code, that is trusted on the basis of having been signed by a special editor cert which the user has to accept. You may have encountered it if you've ever used windows update. Not sandboxed at all, unlike Java.

I don't see it in netstat -s. Possibly you'd have to hack up a netfilter rule.

There's nothing the XP computer can do to fix that, as it is the victim of the delays and needs the cooperation of other hosts that are to some degree involved in causing the problem. As I understand it, ECN on the Mac enables the Mac to co

Continuing this bufferbloat conversation, here is a shameless plug about CoDel: https://news.ycombinator.com/item?id=3948725 It implements the “look at the time you've had a queue above threshold” bit.

This is a new algorithm to fight bufferbloat by Kathleen Nichols and Van Jacobson. It has no tunables, and is able to adapt to bandwidth changes of two orders on magnitude, making it suitable for radio links (3G, WiFi). Patches for the Cero

Huh, I wasn't aware ECN wasn't enabled everywhere yet. To enable it on Linux: sudo sysctl net.ipv4.tcp_ecn=1 Across reboots: echo net.ipv4.tcp_ecn=1 |sudo tee /etc/sysctl.d/10-ecn.conf Other OSes: https://en.wikipedia.org

Sure. Quite possibly we'll just see refinements at the edges of what we have access to (because at most scales, physics is already very accurate) rather than outright revolutions.

We've done things that seem like magic to some hunter-gatherer; that doesn't imply everything that seems like magic to us will come true. (does anyone have a catchy name for this fallacy?) The boundary between things we know to be possible

Since ureadahead looks at blocks and not files, it has a potential speed advantage if the boot process is opening some large files but not reading them in full. Edit: except the ureadahead packfile only points to the blocks and files, it do

The OSX feature apparently notices files which are slowly appended to (downloads) and defragments them. It does not reallocate a set of files (such as the ones touched at boot) to be adjacent on disk, which is what e4rat does.

I have btrfs (with lzo compression) on a rotating disk, and the boot feels a little slower (one or two minutes total?) for reasons I haven't really examined. I'll have to check if something messed with ureadahead.

I wonder how much improvement that brings over standard ureadahead (see yason in this thread for how they differ). For zram, no need for a ppa, a zram-config package has been added in precise.

As I understand it the motion blur is a product of lossy compression (CCD has very short pixel-local exposure times; the shearing the article refers to appears when sweeping the whole image); which means that yes, stabilisation algorithms w

To be fair, faster answers + the ability to undo a do-what-I-mean guess lets me correct Google's assumptions pretty fast. The tools at the left allow for some quick refining as well; that's pretty useful when I need particularly fresh resul

I'm a bit wary of calling an fpm-generated deb a native package, those are about as well integrated as a checkinstall (make install -> deb) or an alien (rpm -> deb) package. fpm may still be useful for this use case, but it doesn't

He mentioned the data structure is large, so it's a safe assumption to say the cpu caches won't be useful except maybe for the very top of the tree, and that there is no locality when traversing a tree path.

Distributed thinking isn't rational even if the actors are, it all depends on the rules of the game. For example, the optimal strategy in a prisonner's dilemma hurts both players; tragedies of the commons have similar effects at a larger sc

This is a biological metaphor that has been stretched too far. Natural selection has produced impressive systems and ecosystems that provide some redundancy, but humans are much better at deliberate effort and fast conscious feedback loops,
