Comment No really, READ IT ALL (Score 2) 170

It's pretty obvious who is and who is not reading the article here:

In short, there seems to be no evidence, at present, that the D-Wave machine is going to overtake simulated annealing for any instance size.

The author concedes that it is possible that this may happen, but:

Well, I concede that almost anything is possible in the future—but “these experiments, while not supporting D-Wave’s claims about the usefulness of its devices, also don’t conclusively disprove those claims” is a very different message than what’s currently making it into the press.

Additionally the author wants this to succeed because of possible results of its failure:

Academic QC programs will be decimated, despite the slow but genuine progress that they’d been making the entire time in a “parallel universe” from D-Wave. People’s contempt for academia is such that, while a D-Wave success would be trumpeted as its alone, a D-Wave failure would be blamed on the entire QC community.

Seriously, read the whole damn article.

The problem is that it's not faster, and while there's a study that concludes it is, the blog post specifically invalidates this:

Namely, the same USC paper that reported the quantum annealing behavior of the D-Wave One, also showed no speed advantage whatsoever for quantum annealing over classical simulated annealing. In more detail, Matthias Troyer’s group spent a few months carefully studying the D-Wave problem—after which, they were able to write optimized simulated annealing code that solves the D-Wave problem on a normal, off-the-shelf classical computer, about 15 times faster than the D-Wave machine itself solves the D-Wave problem! Of course, if you wanted even more classical speedup than that, then you could simply add more processors to your classical computer, for only a tiny fraction of the ~$10 million that a D-Wave One would set you back.

About the paper claiming it's faster:

As I said above, at the time McGeoch and Wang’s paper was released to the media (though maybe not at the time it was written?), the “highly tuned implementation” of simulated annealing that they ask for had already been written and tested, and the result was that it outperformed the D-Wave machine on all instance sizes tested. In other words, their comparison to CPLEX had already been superseded by a much more informative comparison—one that gave the “opposite” result—before it ever became public. For obvious reasons, most press reports have simply ignored this fact.

Same thing that happened with hotmail. They switch to Windows servers, it crashes and burns horribly, so they switch back. There's no quality control, no development, it goes to hell, and everyone switches to the far superior service Google offers (since they decided to grow their own and not acquire youtube).

Then they switch everyone over to zune.com or something to try capitalizing on their name .. or perhaps trying to gain a name, it's hard to tell really .. complete with commercials about people deleting hundreds of hours of video in a single click in the middle of other unrelated activities, because you know that's the feature we've all really been missing.

Yes, and that there is a "brick wall". First, the article may be wrong; exascale might hit by (or before) 2020. They've got 7 years. That's a long time in terms of technology; the first teraflops supercomputer was 1996, merely 17 years ago. Speed increase can't happen indefinitely, but we're not talking about indefinitely, just exaflops. Even if this is not achieved by 2020, they have not hit a "brick wall", because development will continue until it is achieved. There is nothing even slightly theoretical making exaflops unachievable.

In short, even if the article is right, it's wrong.

Sure but they're one of many. Even if one of the many don't accomplish this, surely another will. If not by (or before!) 2020, sometime later. People aren't just going to give up if it doesn't happen by some arbitrary date. This is my real point.

These days, how much is really revolutionary anyway? So many new supercomputing announcements are "we threw N parts at this, so it's Yflops".

Blech.

How can you go from "severe scope creep" to "hey let's add more scope!" with a straight face? Clearly, HTML is far beyond its original intent, and getting by on horrible hacks. Browsers can now do things on a shiny new 3.5GHz machine and $600 video card at nearly half the speed they could 14 years ago on a 200MHz P2 with a Voodoo2. Quake 3! Woo!

College textbooks are largely irrelevant in the age of Internet. They only exist to keep publishers and bought teachers rich.

This is really not the case at all. Your class may "require" stupid irrelevant textbooks; I had many like this myself. However, textbooks, i.e., field-specific moderately expensive ($50-80+) texts are often the only useful place to find information. Yes, you can find probably all the information on Java you care about on the web. However, you will have a much harder time finding information on compiler optimization, writing garbage collectors, or other "real" CS topics on the web, beyond very rudimentary hand-wavy descriptions.

You can find a lot of this information on the internet, usually in the form of papers behind a paywall (e.g., the ACM). However even then, it's usually not condensed into a useful form such that you can easily evaluate the pros and cons of various approaches. If you have to deal with these things, $100 for the textbook suddenly seems very reasonable.

Building your professional library as a student can be nice; however it would also be nice if professors focused on books that will have a long useful life.

Then take 20 seconds and search the web for real sources of information, not Slashdot or Random J Dude's blog about Java and how vaccines are giving us autism or whatever. Subscribe to the ACM or similar for your field and get access to great deals of actual research. Not cheap, but neither are print journals, and the coverage is far better.

Complaining about information not coming to you and that you have to discover it is pretty lazy in a very bad way. Assuming your slim selection of reading is actually giving you a broad picture of what's going on, especially if you're only reading a few sources, is only fooling yourself. However, the technology to actually collate information into an easy-to-read list obviously already exists.

OK I call BS:

There's a lot of awkward inconsistencies such as sometimes when you download a game from the store you get an unlock file, and others you get the full game, and other times you get random extra downloads on top, then it's non-obvious what files you can delete so you end up with these files that do nothing but you're unsure if it's safe to delete them.

This shows you have never actually used a PS3. After installation, there is just "the game". "Game data" and "Patch/DLC" may exist at some point, but only if you have run the game or downloaded them. These are all clearly labeled (assuming you know the definition of "DLC" or "Settings") and in a single location with the same game icon. There are no "files" that are "non-obvious".

For games where you download a demo and an unlock, these are merged into a single, unambiguous game. There is not even a separate "game data" at this point. From your description, it sounds like you saw someone download a demo, a game, and some DLC, and thought these were somehow all required to run the game.

While the demo+key solution may not seem like the most elegant, it's pretty nice when you try a game, decide you like it, and then don't have to spend another hour redownloading the full version .. you can just unlock it and continue playing in a minute or few total.

I do feel that objectively the 360 feels more polished, the controllers not only feel better to hold and use, but the PS3 buttons even just outright feel like they don't respond sometimes.

This is not "objective". Subjectively, to you, the 360 feels "more polished" and the controller "feels better to hold". I have the opposite experience; the 360's controller is OK, but I prefer the DualShock (and I have big hands). This is the first time I have ever heard of a non-broken PS3 controller feeling "like they don't respond sometimes".

Patching is horrendous, I had to download many 10s of gigabytes of patches for the handful of games I bought

OK at this point it's clear we're dealing with FUD. The biggest patch I've ever seen was around 200MB. The biggest downloadable full game I've ever seen is 14GB (though I typically buy discs .. infamous 2 was free for PS+). Never have these required "10s of gigabytes of patches".

The sign up process to Sony online was brutal, the site kept going down and I desperately tried to recover an SOE account from years ago but apparently that's a different Sony online thing to the Playstation one and that made it all a bit of a pain.

Er... so filling in a few blanks on the screen was "brutal"? I suppose if you're really a cluebie, you might confuse SOE and PSN, but nowhere is SOE or an SOE account mentioned in the signup process. Perhaps it would be nice if they merged these at some point, but that would get its own share of complaints. And let me tell you about the "recovery" process for XBOX/GFWL accounts...

In any case, this entire rant comes off either FUD, an incredibly inexperienced user, or someone who uses a 360 and watched their kids using a PS3.

#1 most important thing I consider when purchasing a laptop is that it doesn't come bundled with Windows. [...] Personally, I would and have paid more for laptops that come without OS.

This is actually kinda silly; there are businesses (including MS) literally paying money to have their stuff bundled on there which helps subsidize the box. If you buy it and nuke Windows and everything on the box, never booting it, you're costing these idiots money. Otherwise you will pay more yourself.

Plus, you get that little thrill when you d the Windows partition in fdisk.

Exactly why this is another troll piece. There is no evidence of "stigma" ... Linux has never had stigma attached, except maybe in the minds of Microsoft management. When has "Linux" and been "a mark or token of infamy, disgrace, or reproach"?

As a counterexample, Steam just got released for Linux and they had a big fanfare and sale. Where's the stigma?

There is no grand conspiracy to hide the fact it's Linux; Linux is already everywhere and it doesn't need marketing. It's cool that way.

And of course, Microsoft makes a "vacuum cleaners need plugged in" analogy while not realizing they are getting "unplugged", so to speak. With these fancy new vacuum cleaners, you only need to "download" the electricity when you're not using it! It's almost as if being plugged in all the time is highly inconvenient.

Sadly while T-Mobile has always had really good pricing in relation to AT&T and Verizon, they've always had really crappy coverage (though their service in covered areas always seemed decent). If you are someone who spends most of your time in a 4G-covered area, great. Otherwise, it's pretty much Verizon or bust (AT&T being pretty much the worst of both). Somehow T-Mobile always seems to get the best devices, though. I guess that and pricing set them apart.

If they can get their coverage up to rival Verizon, though, we can expect real competition... or increased prices.
