ARM In Supercomputers — 'Get Ready For the Change'

Victor Liu Re:Does it really matter? (238 comments)

On the point or portability, there's then a distinction of your focus. If you do research on numerical methods, then yes, you would write highly optimized code for a particular machine, as an end in and of itself. I myself am merely a user, and our research group does not have the expertise to write such optimized code. We pay for time on supercomputing clusters, which constantly bring online new machines and retire old ones. Every year our subscription can change, and we are allowed to use resources on different computers. Therefore, from my standpoint, portability is very important. Otherwise, if we were to write our own code in-house, we basically have a 1 year (ok, fine, maybe 2 or 3 year) window in which to develop, test, and run it. It just doesn't seem worthwhile to spend so much effort developing a one-time use piece of code. I'd rather write something which will outlive my stay in the research program.

ARM In Supercomputers — 'Get Ready For the Change'

Victor Liu Re:Does it really matter? (238 comments)

As someone who does heavy duty scientific computing, I wouldn't say that "most" of the actual process power is in GPUs. They are certainly more powerful at certain tasks, but most applications run are legacy code, and most algorithms require substantial reworking to get them to run with reasonable performance on a GPU. Simply put, GPU for supercomputing is not quite a mature technology yet. I am personally not too interested in coding for GPUs simply because the code is not portable enough yet, and by the time the technology might be mature, there might be a new wave of technology (like ARM) that could be easier to work with.

Microsoft Surface Struggles to Ship A Million Units

Victor Liu Re:The actual reason (375 comments)

Why is there so much hate for netbooks? I've got a 10 inch eeePC from 3 years ago and I absolutely love it. I use it almost everyday and it still has great battery life of 3-4 hours down from 7-8 originally. Plus having a nearly full size keyboard makes doing actual work possible.

Intel Designs Faster, 3D Transistor

Victor Liu Re:Cooling (141 comments)

No. The fin is at one of the bottom-most layers of the chip. All the metalization layers for wires sit on top of the transistors.

Flash On Android Is 'Shockingly Bad'

Victor Liu Re:"None" is better than inconsistent? (657 comments)

Yes, none is better. I'd rather not be given an option if I don't really like either. Furthermore, if you accidentally click on a link with Flash content, your browser may slow to a crawl.

A New Species of Patent Troll

You purchased some random kitchen tool (1) without knowing what it does and (2) without any idea what you were going to do with it? Man have I got some fine products to show you...

You mean to say they plan to also build a weather machine to replicate the ever sunny skies here?

Something For (Almost) Every Developer

Victor Liu Re:VS upgrade cycle (263 comments)

From what I can tell, VS2010 is going back to the old model of just including all the DLLs in the app directory. VS2008 was a huge pain with its manifests and SxS assemblies and crap.

Why You Should Use OpenGL and Not DirectX

Victor Liu Re:Killer App (515 comments)

... and that killer app would probably be easier to write in DirectX.

Why You Should Use OpenGL and Not DirectX

Victor Liu Re:OpenGL and the rant about marketing (515 comments)

This is not entirely true for a framework like OpenGL. You surely can add your own features or improve performance on your end, but these changes must be incorporated into graphics card drivers by vendors in order to have a wide audience. This is where it helps to have the industry clout that Microsoft does (not that this is necessarily a good thing, but they have the power to push through changes into hardware using their DirectX specs).

The Most Useless Key On My Keyboard Is...

Victor Liu F1 key (939 comments)

Real men don't ask for help! But seriously, every a Windows pplication uses F1 as a shortcut key for opening up Help. I so rarely use Help that I really don't need a shortcut key for it. Worse, it's next to Esc, which I do use quite often to unselect active menus, etc. Accidentally hitting F1 in, e.g. Visual Studio, wastes a good few seconds as the bloated Help window loads.

Making Magnetic Monopoles and Other Physics Exotica

Victor Liu Re:Monopoles Are Easy (104 comments)

That most certainly does not result in a monopole. You'd get a quadrupole I think.

Modern LaTeX Replacement?

Victor Liu Re:Our professors seem to favour MathType (918 comments)

Note that MathType is only really for adding equations into Word documents; it supplants the MS Equation editor, and probably isn't meant for a whole lot more. My adviser (in EE) also uses MathType for formulas and class notes. However, these tend to be short documents that are less than 10 pages long typically, with no need for serious cross referencing. Once you start trying to write serious documents on the order of a hundred pages, with cross references all over the place to equations, tables, and figures, MathType and Word's capabilities begin to pale compared to LaTeX.
