Apple Ships OS X 10.7 Lion 'Gold Master' For July Push

Shin-LaC Re:Is XCode included in the download? (370 comments)

Apple contributed a lot of changes upstream, but they were not merged. At some point, they stopped and decided to focus on LLVM instead.

What are you talking about? gcc4 comes with Xcode (both the free Xcode 3 and the cheap Xcode 4).

Dropbox TOS Includes Broad Copyright License

Shin-LaC Re:Out of context (213 comments)

They should have said "to the extent necessary to perform the actions you request", or something to that effect. Instead, they say "to the extent we think it necessary for the Service", which basically means "however we want".

New Imaging Technique Helps Explain Unconsciousness

Shin-LaC What a silly spelling (78 comments)

It looks like they tried to type "Feiter" as if they were normal people naming a thing, but they forgot their caps lock on.

It always seemed to me that Chrome uses even more memory than Firefox.

NSA CS Man: My Tracking Algorithm Was 'Twisted' By the Government

Shin-LaC Why is it so bad, anyway? (267 comments)

Everybody knows that the US government intercepts the world's communications. If they now do the same to Americans, it just seems fair.

The Stanford Class That Built Apps and Made Fortunes

Shin-LaC Re:i call bullshit (125 comments)

Oh, I hear you. I'm getting an engineering degree, and it's fucking worthless. The best I can hope for is to make a decent living while contributing to the fortunes of people whose life has been and will always be much better than mine.

Essentially, there are three tiers of skills in our present world. The gold tier is entrepreneurship. The people who have it become rich and rule the world. The silver tier is money-twiddling. These people may not be gold, but they are close enough to money that they get rich as well. Then you have nothing, and twenty levels down you have the shit tier, where all the other skills are. We techies can at best aspire to be kings of beggars.

Comcast's 105MBit Service Comes With Data Cap

Shin-LaC Misogynist analogy (372 comments)

Basically, it's like marrying a gorgeous woman. She looks really hot, but you can never just let your lust run wild, because she thinks too highly of herself. Every instance of intercourse must be bargained for, and you're lucky to get it once a week; and when you do, she just lies there like a dead tuna. Soon, you begin to question whether it was worth spending so much money and effort on her.

OpenOffice.org To Be Given Back To the Community

I don't like the LibreOffice application icon. It looks too much like a generic document.

Firefox 5 In Aurora Channel

Shin-LaC Re:Please win back the long-time users (161 comments)

I also use Chrome on OS X, and the big feature that enabled me to switch was Keychain integration. I used Safari before, and the ability to share passwords between the two browsers has been invaluable. This feature has been requested for Firefox years ago, but never delivered. Until it is, I can't consider it a serious contender on OS X.

New Medical Camera the Size of a Grain of Salt

Shin-LaC Are you blind? (132 comments)

A cubic millimeter is hardly "at the size limit that the human eye can see unaided". A fleck of dust is quite a bit smaller than that, and perfectly visible.

Google Cuts Chrome Page Load Times In Half w/ SPDY

Shin-LaC Re:SPDY clarifications (310 comments)

Also, from the FAQ:

Q: Doesn't HTTP pipelining already solve the latency problem? A: No. While pipelining does allow for multiple requests to be sent in parallel over a single TCP stream, it is still but a single stream. Any delays in the processing of anything in the stream (either a long request at the head-of-line or packet loss) will delay the entire stream.

This does not make sense. You're still using TCP, which is a reliable transport protocol, which means packet loss is dealt with at the TCP level, and not seen by SPDY. So the effect of "delaying the entire stream" is exactly the same as with HTTP. The only difference is that you're using fewer TCP connections (one instead of several - in fact, this is one of your selling points!), so the probability that a request will be affected by packet loss in an unrelated request *increases*: packet loss slows down all subsequent traffic on SPDY, since it's sharing a single TCP connection, while with HTTP it only affects traffic that uses the same connection (out of several).

Google Cuts Chrome Page Load Times In Half w/ SPDY

Shin-LaC Re:SPDY clarifications (310 comments)

In the real world, packets loss rates are typically 1-2%, and RTTs average 50-100 ms in the U.S.) The reasons that SPDY does better as packet loss rates increase are several: SPDY sends ~40% fewer packets than HTTP, which means fewer packets affected by loss.

But the packets are bigger. If packets are lost due to noise, increasing the size of a packet increases the probability of having an error within it. 10 dollars says you "tested" this in a simulation by fixing the probability of losing a packet, instead of fixing the error distribution. That's going to overestimate the improvements of having fewer smaller packets.

Google Cuts Chrome Page Load Times In Half w/ SPDY

Shin-LaC Re:BAD (310 comments)

One year doesn't strike me as particularly slow, either. And what's the point of asking people to contribute now, when you've already designed and implemented your idea and put it in production? Isn't this the same Google that froze the WebM specification? Openness for standards is not the same thing as openness for source.

Firefox 5 Details: Sharing, Home Tab, PDF Viewer

Shin-LaC Re:Time for a reboot? (453 comments)

Hi there, I'm a Mac user. I won't care about anything you do in Firefox until you give me Keychain integration. Keychain support is what made Chrome a viable alternative to Safari, and in fact I mainly use Chrome at the moment. But without all my passwords, the barrier to seriously trying out Firefox as my main browser is just too high.

WebKit introduces fastest JavaScript engine

Shin-LaC Shin-LaC writes  |  about 6 years ago

Shin-LaC (1333529) writes "In a post on their official blog, WebKit developers introduced the "next generation" of their JavaScript engine, SquirrelFish Extreme, claimed to be twice as fast as its predecessor. The post lists several changes contributing to the performance improvements, including "bytecode optimization", a "polymorphic inline cache" (which sounds similar to V8's "hidden class transitions"), and a "context threaded JIT" compiler which generates native code (currently only for x86 processors) and is also applied to regular expressions. The new JavaScript engine is already available in the latest WebKit nightly builds.
According to comparative benchmarks, the new engine is around 35% faster than the V8 engine recently introduced in Google Chrome, and 55% faster than Mozilla's TraceMonkey."
