We should be much more worried about the higher level interfaces/languages that app developers actually program to. They're stuck in the stone age. The level of abstraction needs to be raised many notches and programmers need to b

It's not literal even in Itanium's case, as it's about leveling the voltage droop and not temperature. There can be many other kinds of run-ups to steady state happening in processors for microbenchmarks. Caches/TLBs, br

I wouldn't count 55,000 out of 3 billion Internet users as "wide use". There is virtually no chance that a random person you want to communicate with is set up with PGP and connected to the web of trust.

It doesn't special case the asm.js JS subset same way as Firefox does, but V8 guys are paying attention to optimizing asm.js-style code.

That's picking data, switching to swedes from scandinavians generally.

by zurn 12y ago
The web page doesn't say anything about asm.js - so this is a generic JS JIT that happens to beat V8 in asm.js? V8 doesn't explicitly support asm.js so it's easier to beat than Firefox.

You can do the exact same thing with disks to arrange data sequentially though.

staving off catastrophic climate change is the issue, more natural gas doesn't help.

Someone should set up a bet about what point in time more than 50% of MITM attempts with revoked (& Heartbleed-snarfed) certs will be caught by default configured browsers. "Never?" This and lack of PFS are much bigger catastr

KVM support indeed sounds nice, though they advertised it already before for POWER7/PPC970 hardware... Re endianness, Linux is comfortably bi-endian and so is approximately all portable Linux software. Certainly there isn't any &q

IBM's semi guys have been doing all kinds of wacky things with low volume chips (and also high-volume, see eg. prev gen consoles). For example their System/360 compatible mainframe CPUs are doing 5.5 GHz now. https://en

AMD has also been fabless for a while. Somehow the chips keep showing up...

So they're saying it's easier to use a brand new incompatible little endian Linux personality, with associated new toolchains and new ports of low level stuff etc compared to the standard Linux PPC64 stuff... Sounds kind of surpri

IBM beat that by a hair or two, 5 GHz POWER6 processors came out in in 2007. And the newer, faster POWER7 chips are clocked lower. Clock frequency != performance.

WebRTC works pretty well on Android. But apparently Apple has kept it out of iOS Safari and doesn't allow other browsers to implement it?

Would be a shame since SNI appeared in browsers ~2007. IE 6 is hardly worth wasting the Internet's last IPv4 space on.

> you can't even write a container (a map/dictionry/linked-list/etc) without giving up type safety Nit: they're typesafe (when done using interfaces), just not statically so.

Linux doesn't have a good culture of security. Local root bugs are dime a dozen. Security fixes in the kernel are not flagged as such. There's no systematic effort to stop the most common types of security bug (memory bugs in some

The Chrome sandbox setup doesn't correspond to a regular linux application talking to the kernel though. It has a 2-layer sandbox, with the seccomp-bpf and setuid sandboxes. They restrict the kernel interface to a whitelisted subset.

How is the isolation in Xen better than Chrome sandboxes - do you mean the attack surface is smaller, the code quality better, or the task somehow inherently simpler/easier? From where I sit, vulnerabilities in virtualization have seen
