Boffins: There's a ninth planet out there – now we just need to find it

stephanh

Re: Planet?

Actually Uranus is only 14.5 times the mass of Earth, so it would seem quite possible for it to be a gas giant (well, "ice giant" really) like Uranus and Neptune.

Re: Planet?

But the rules don't care about mass. That is, by the way, what makes them so ridiculous. You would think the "dwarf" label would somehow refer to size but it doesn't. So a dwarf gas giant planet is a completely feasible outcome of the current rules.

In fact, it is generally considered possible that the outer Kuiper belt may still contain a Mars-sized or even Earth-sized object, just judging from the observed mass distribution of Kuiper belt objects. However, such an object would still not qualify as a "planet", even if it would be the size of Earth!

Microsoft offers Linux certification. Do not adjust your set. This is not an error

Re: Hmmm.

I don't. The only thing surprising about this is that it took them so long. Of course, Microsoft would prefer you running Windows on Azure. But if you are going to run Linux, they would rather have you run it on Azure. Because otherwise you might go to Amazon and who knows, one day you might decide that you can run your Windows VMs on Amazon too.

In other words, like every other business in existence, they would prefer you to use their toothbrushes AND their toothpaste, but if you insist on Penguin-brand toothpaste, then please at least use our brushes.

(I am not sure if they see this mostly as offensive or defensive. Offensive, in the sense of getting a foot in the door at Linux-only shops, or defensive in the sense of preventing Amazon getting a foot in the door in Microsoft-only shops.)

Re: I'm puzzled by the example

That's nothing.

The capital of Flanders is Brussels, even though Brussels is not part of Flanders. Perhaps they should have chosen Jerusalem instead, just to annoy everybody.

Re: Wow! 3 (count'em...THREE) files at a time!

It's still limited to three windows *visible* at the same time, which is completely ridiculous in a time where 27" monitors are becoming standard for software development work.

I checked the configuration file and this seems not to be configurable. As an aside, I noticed that the settings.json configuration file is in fact not valid JSON (comments are NOT allowed in JSON!).

Linux

Re: On linux? Meh, I'll stick with vim

Vim has had syntax highlighting for decades.

I just counted them, the standard distribution comes with support for 585 languages. Including such pearls as Cobol, 68000 assembly, ABAP, Verilog, and OpenSSH server[1] configuration files.

[1] For the OpenSSH client configuration files there is a separate syntax colouring. Of course.

Re: Ridiculously bloated!

Dunno about TECO but Ex is bloatware.

"Ex is very large - this version will not fit on PDP-11's without overlay software. Things that can be turned off to save space include LISPCODE (-l flag, showmatch and lisp options), CHDIR (the previously undocumented chdir command.)"

Research: Microsoft the fastest growing maker of tablet OSs ... by 2019

Facepalm

the joy of significant digits

"iOS will grow, but only from 22 to 23 per cent."

Well, glad they can predict what happens in 2019 down to 1% accuracy. I don't believe they can even measure current market share that accurately.

Have these people ever heard of error bars?

Microsoft Windows: The Next 30 Years

Re: I'll bet money...

If Microsoft stopped all its new product development today it could still be wildly profitable for at least 20 years by doing licensing and support for its currently installed user base.

Actually, this might be a better strategy than the one they are following now...

Re: @ Chairo (was:Thailand is the only Asian country never to be colonised)

Asian countries never colonized:

Turkey & Japan as already mentioned

Iran/Persia - territories lost to Russia but kept its independence

China - many "unequal treaties" and territorial concessions (Hong Kong, Macao) but never colonized as a whole

Nepal - had to cede territory to the British but kept its independency

Bhutan - similar story as Nepal

Mongolia - part of Qing China, declared independence after fall of Qing, under USSR influence but nominally independent

It's Gartner Magic Graph of Wonder time! And Google won't be happy

stephanh

A modest proposal

May I propose the following to the esteemed editors.

Whenever Gartner unleashes yet another of their reports on the world, rather than discussing the latest, could The Register take the report of, say, two years back, and review how much of it has come true?

I think this would be most enlightening.

NASA boffins on Pluto: We see skies of BLUE and... RED water ice

Re: RE:

Interestingly, on my OS X machine:

$ ulimit -n

256

So max 256 file descriptors per process. More than 99, but not greatly so.

(Of course, it is mostly so that buggy programs which open files in a tight loop don't bring down the entire system.)

The Steve Jobs of supercomputers: We remember Seymour Cray

Boffin

Cray FP != IEEE 754

Cray floating point arithmetic was notoriously erratic. Most floating point units use internally more precision during calculation to minimize round-off errors, but Cray didn't do that because of performance concerns. The result is rounding errors that would not occur on IEEE 754 FPUs.

See: http://www.cs.berkeley.edu/~demmel/cs267/lecture21/lecture21.html

"In particular, this means that if a and b are nearly equal, so a-b is much smaller than either a or b (this is called extreme cancellation), then the relative error may be quite large. For example when subtracting 1-x, where x is the next smaller floating point number than 1, the answer is twice too large on a Cray C90, and 0 when it should be nonzero on a Cray 2."

This does mean that algorithms written using the IEEE 754 guarantees on floating point rounding behaviour to avoid catastrophic cancellation (e.g. Python's math.fsum) don't work on the Cray.

Re: More Linux performance data please

If you want Linux, it makes definitely sense to look into second-hand laptops. Generally, the older the machine the better driver support. Also, more information is available on the Internet on compatibility.

Re: inverse square law and all that

The EM radiation of a cellphone is absorbed by the skin and does not penetrate further into the body. The skin is (slightly) heated, which appears[1] to be completely harmless, at least at the levels emitted by your iphone. Swallowing your phone is thus not recommended as it will lead to bad reception. Also make sure you are not holding it wrong.

[1] As demonstrated by countless studies, which you may want to believe where all funded by the big conspiracy for corrupting our precious bodily fluids.

Re: There's a special place for people like that...

Perhaps the wiring in the house was functioning as a low-frequency radio receiver. Low-frequency sounds would be more felt than heard. Earplugs would not be effective in such a case.

Microsoft's Bing hopes to bag market share with ... search apps

stephanh

30% of what?

Bing has almost[1] 30% of the US[2] desktop[3] market...

provided we also include Yahoo in their numbers (at approx 10%) which uses the same engine. Unfortunately for them, for the Yahoo use they get no revenue, in fact they have to pay[4] them.

[1] "Almost" is "not" spelled with six letters.

[2] Globally, Bing is "almost" as big as Yandex.

[3] So not including this newfangled "mobile" stuff.

[4] The payments accounted for 25% of Yahoo's revenue for 2013.

Admins! Never mind POODLE, there're NEW OpenSSL bugs to splat

stephanh

Re: heck, the way things are going

Industry average for "good quality" software: 1 defect per 1000 lines of code. Source: http://www.net-security.org/secworld.php?id=14871

OpenSSL source code: approx. 500,000 lines of code.

So four down, 496 bugs to go. And that is assuming the people adding "features" aren't putting them back in faster than they can be found.

Bash bug: Shellshocked yet? You will be ... when this goes WORM

stephanh

Re: Stupidest bug ever

Apparently the idea is that you can export a function, like you can export a variable (meaning it gets inherited by subshells). The function body is then communicated through an environment variable.

Example:

$ function foo { echo hello, world; }

$ export -f foo

$ tclsh # since bash doesn't show the magic variables...

% set env(foo)

() { echo hello, world

}

It just works?

As the formerly proud owner of a Macbook Air,

I just downloaded the bash source, downloaded the patch,

applied the patch, compiled, checked the resulting binary

and replaced /bin/bash and /bin/sh.

It Just Works. Kinda.

In the mean time, my Ubuntu machine got

the fixed version through the automatic update.
