Give up 4:3/5:4 monitor? There's no reason if it still works.

IMHO, 4:3 or 5:4 (which I'm using right now) is much better for most of the computing tasks I do -- see my cousin post on text line widths. I'd gladly get a new monitor with such dimensions (and a modern resolution, naturally).

For the inevitable comments on turning a widescreen monitor in a vertical orientation, please go and educate yourselves on subpixel font rendering. Of course, as videos don't use that, an ideal monitor might have their subpixels oriented in the long direction, so it could serve both purposes optimally.

Comment: Re:Theora is like MPEG-4 ASP (DivX) (Score 1) 81 81

I'd prefer cooler vp8 or even cooler vp9 because they soundly beat theora in rate/distortion.

(Did you mean "theorems"?)

I'm aware of the Theora codec. "Theora" is also a fancy Latin-like plural for "theorem", though probably not technically correct in English (cf. virus/viri).

You just need to stretch out your browsers windows so that it is wide enough to accommodate the headline layout as envisaged by the might /. design team.

Or in other words the idiots at /. designed a layout that looks good on their monitors and never tested it beyond that. Why should they, as it works on their systems!

The /. designers must now be wondering why newspaper text is laid out in narrow columns. After all, a newspaper has a lot of horizontal space, so why don't they just print long lines of text...

Comment: Re:No HDMI 2.0 support, not even in Fiji (Score 2) 87 87

Displayport to DVI/HDMI can be done with a passive adapter. Basically, DP can output DMI/HDMI signal once it detects that kind of a monitor. I'm not sure if this applies to newer versions of HDMI, though.

The whole separation between AV and PC worlds seems silly anyway. For example, the first time I connected my AMD GPU to my "computer" monitor via HDMI, the computer was detecting/sending a correct resolution, but the output was shrunk, leaving black bands on all sides and the image ugly and blurred. It turned out that the HDMI output does 15% underscanning by default, presumably to compensate something that TVs do. And presumably because HDMI implies TV which implies I don't care for exact pixels (what's this 4k or 1920x1080 crap anyway), just a huge picture. Fortunately, the default could be easily overridden. I understand this kind of thinking might have been important in the days of analogue TVs, where you needed the occasional adjustments to account for different source materials in a less well-defined analogue display, but in the days of full HD and beyond it's just idiotic.

Comment: Re:"Up To..." (Score 4, Interesting) 81 81

"Up To" is a weasel word/expression. It doesn't actually mean anything, or at least nothing useful to the consumer.

To a mathematician, knowing that something is "up to" a number is very valuable. Not only does it guarantee that a value is bounded, it also gives an explicit upper bound. In this case, when the rate of bits per second is bounded, we know that the amount of data as a function of time is Lipschitz continuous, which enables all kinds of cool theora to be applied. So while it may not seem much to a mere mortal consumer, mathematicians all over the world are overjoyed.

Comment: Infinity... or maybe not (Score 1) 1067 1067

In measure theory, a positive number divided by zero is defined to be infinity, and there's likewise a negative infinity. OTOH, in complex analysis there's a single point at infinity. I'm sure there are other well-defined notions of infinity, and you can dig deeper into things like compactification. However, none of the definitions of infinity is equal to zero, for the obvious reason that 0 times 0 is still 0. Also, you need rules such as infinity times zero being undefined, so by having a numerical value for infinity (like NaN) would just push the problem further. The unfortunate fact is that the set of real numbers is not closed with respect to division, and you have to deal with it one way or another, rather than hiding the problem.

Humans do not work that way! It's like font scaling where larger sizes are proportionally slimmer, if you want a geek analogy. The body mass index is mass/(height squared) for a reason, not height cubed. Of course, the square law isn't precise by any means, starting with the fact that healthy humans come in many different shapes and proportions.

Comment: Re:Skype ui inconsistencies (Score 2) 186 186

Speaking of Linux, I recently uninstalled Skype as it was the only software that needed 32-bit compatibility libraries. I didn't want to worry about updating them all the time for one crappy closed application. I guess this isn't such a problem on Windows which provides this compatibility anyway, but I thought it's there for running old and unsupported binaries, not some new releases in a 64-bit era.

Aren't you glad you're not getting all the government you pay for now?
