If Java ( or Pyhton etc. for that matter ) were fast enough why did Google choose C++ to build their insanely fast search engine.
Because their developers knew it better? Because it had better 64-bit support when they started it? Because full GC's weren't compatible with their use case and IBM's parallel GC VM hadn't been released yet? Because they could get and modify all the source to all the libraries?
I don't know the answer, but there are a lot of possibilities besides speed. You're jumping to an awfully big conclusion there, Mr. Coward.
I can vouch that FiOS's 20/5 service really does deliver that speed almost all the time. Occasionally it dips a little bit (not sure why), but generally I can download a couple gigs in 15 minutes or so and upload my site way, way faster than with Comcast.
I read all 3 Baroque books, and I don't know why but I found them immensely entertaining while everyone else I know stopped somewhere in the first book (which in subsequent publications was itself turned into 3 books). They were like a kid's serial novel from the 1800's or something. Like reading an entire narrative based on all the "150 years ago in Scientific American" sections. The only thing that frustrated me about the books at all was not knowing whether I actually knew any accurate history after reading them, since large portions of the events and characters are fiction with enough reality thrown in to make it interesting. (Kind of like some of the Illuminatus Trilogy that way.)

Why Corporates Hate Perl

I don't think so. It's much, much harder to write crappy code in Java than it is in Perl. Java enforces a lot of practices in its syntax that annoy the code hacker type but make the software much more maintainable down the road.
Oh, and queue the predictable (and incorrect) responses about how you can't "steal" digital images. To steal a photo or a picture, you would have to take a physical copy belonging to someone, and deprive someone else of that physical copy, without their permission according to SlashDot, but not the English dictionary.
Pet Peeve of mine: That's not the definition of "steal". It's only the SlashDot conventional wisdom. It's really not that hard to look up words on the internet. Here's a link to a dictionary.
Steal: 1 a: to take or appropriate without right or leave and with intent to keep or make use of wrongfully
Appropriate:
3 : to take or make use of without authority or right
I hadn't watched any of it until I accidentally hit the "On Demand" button on my FiOS TV remote last night. FiOS has "highlight reels" of the Olympics, which is way, way more watchable than the live feed.
Look, I develop Java all day long and work on an enterprise-class distributed workspace written in 100% Java. I also have an app for sale on Apple's iPhone App Store. I'm entitled to my opinion, and I'm not talking from a position of ignorance.
I really do prefer Java as a language. But for user interaction, you just can't beat Interface Builder and Apple's libraries. Especially Core Animation combined with the rest of UIKit for the iPhone.
I would have preferred Apple had adopted Java back in the late 90's and done all of Cocoa in it, personally. That being said, yes, Java as it stands today is more limiting for writing rich client apps than Apple's Objective-C UIKit.
It's not about the language. It's about the libraries. And Apple is currently second-to-none in that department for user interaction.
And really, the amount of Objective-C specific stuff you have to know to write compelling content for the iPhone isn't that huge. The most popular apps seem to be either 90% Interface Builder work, or 90% OpenGL ES work.
One thing I noticed is that the curves and shiny surfaces look really, really smooth but that the straight lines look aliased and fake. The railings look like they were drawn in with a line tool.
You don't have to go esoteric on power connectors to find one reversible... every MacBook and MacBook Pro has the magnetic plug that can go in either way. You can plug it in in the dark, because orientation doesn't matter and it pulls itself into place when it's nearby.
It would be awfully cool if all the connectors were like that. Just sweep your hand along the back of your laptop to disconnect everything.
It's not dispersion either (how clumped-together people are), Japan, the US and Canada have similar dispersions.
[Citation needed]. Almost all of Canada lives in their top few cities. Most Canadians live within an hour of the US border. And Japan is a tiny, tiny country compared to the United States. I think our geography and dispersion really do affect broadband availability, and you'll have to cite more than a vague opinion to convince me otherwise.
That being said, my 20/5 FiOS service with fiber TV and gobs of HD channels is more than I need right now, so I'm not particularly worried.
OpenGL's ES variant is what you need if you're going to the iPhone, which I care a lot more about than Linux. It would be nice to have more native games on the Mac, but I'm not too concerned about that, either.
It's possible the iPhone will keep a solid core of folks on OpenGL until Khronos comes around.
The App Store will need considerable improvement if Apple is to keep up.
Keep up with what? No one else has anything like it yet. At least wait until the first big competitor emerges to decide what Apple has to do to "keep up" with them.
Yes, the App Store needs refinement. On the other hand, Apple now has a HUGE amount of data they can sift through to improve things. They know where referrers are coming from. They know how many hits each page is getting relative to the number of purchases. They have a database of all the descriptions, icons, and screenshots of all applications and can analyze what sells and what gets attention. They know how all the sell rates change as advertising hits their site.
The competitors are going to be coming up against a vast mine of data that Apple can use to refine their product.
Actually, it's not. This URL is there to blacklist Core Location lookups. The original article is wrong and has been debunked repeatedly, most convincingly by Daring Fireball. That's not to say that Apple couldn't revoke a certificate to disable an app, but that's a different mechanism than that described in the article.
Even the title sounds pretty silly to a pilot. Air traffic controllers didn't land the plane-- the pilot did. It MIGHT have been a story if the guy was flying through dense clouds and fog and lost control just as another radar contact was intersecting his vector at high speed or something.
A lot of people are asserting a lot of things on Slashdot, but none of us actually knows what's going on. Or who really broke the cease-fire first. If you weren't there, don't be so sure about who did what when. The fog of war makes that impossible for anyone to know, let alone an armchair observer half a world away.
There's a quote from Mark Twain that goes: "Sorry this letter is so long. I didn't have the time to make it shorter."
I don't consider what you said at odds with what I said at all. I know you were trying to be ironic, but it's true. Apple's genius really is simplifying things such that people consider them geniuses for doing so.
Apple's genius is in deciding what to take out, not what to put in. They don't provide mp3 players that look like your TV's remote control with 200 buttons and dozens of modes. They provide products that give you an intuitive, tactile sense of what you're doing when using their product. Since the iPod, their ads tend to reflect that minimalism as well. It doesn't work for anyone-- some people don't feel like they're getting their money's worth of buttons on an Apple product. But a lot of people find it valuable.
The difference, though, is that people who have frequently used both often tend to develop that exact same opinion. So the marketing really isn't trying to spin much, which makes it even more sticky.
I have no idea. I have no evidence that it is or isn't the JVM, except that on desktop machines slower than the PS3 our enterprise-class desktop Java application loads much faster than a Blu-Ray disc. So I don't automatically assume it's Java. It could just as easily be buffering, initializing various codecs, badly laid out Blu-Ray discs causing lots of seeks, BD+ DRM, updating the local file system with information about the movie, or any combination of the above.
The bottom line is that Java's actually not slow, so my off-the-cuff guess is that it's not the cause of the slowdown.
I'm against the death penalty, but if I were for it I can think of few crimes worse than tampering with our system of government. Enough men and women have died to create it and uphold it that I feel it's at least as bad a crime as murder. Prison sentences and fines seem pretty petty compared to the integrity of our nation.
Do you have any evidence at all that the JVM is contributing materially to the delay? Or just trolling?
Java was invented for embedded devices. It's used in billions of devices around the world. The only reason you happen to know Blu-Ray also uses it is because Microsoft made a stink about it while trying to push their own proprietary standard.
