The Physics of Space Battles

paulatz Re:It seems to me... (427 comments)

Likewise, perhaps *we* can't focus a laser today, but that's not an inherent limitation of lasers even by today's known physics, that's a limitation of our technology

I'm pretty sure the video author is not aware of it, but that's actually a limitation of physics, not of laser technology. The fact that you cannot focus a laser at long distances is related caused by momentum-position duality in quantum physics: Laser is basically a bunch of photons going all in the same direction, with the same color and coherent phases; technically with the same wavevector. However quantum physics dictates that there is going to be a certain spread, uncertainty, in the wavevector of each photon. This uncertainty is inversely proportional to the size of the chamber where the laser was initially pumped, namely the size of the laser gun.

It is really quite similar to projectile weapons: The longer the barrel, the more accurate the shot.

GNOME 3.14 Released

paulatz Re:Commands lines (248 comments)

Undead Waffle (1447615) | 4 hours ago | (#47990621)

And for your convenience gnome 3 removed the partial matches from the alt + f2 window. So much more elegant without all those pesky icons showing up. Also, good luck remembering what the the true name of the calculator is!

gnome-calculator

Seems pretty simple to me.

So easy, that it took you 3 hours to find out

Windows Tax Shot Down In Italy

paulatz Re:What about other devices? (421 comments)

An Italian judge decided this way: It means this is the law in Italy. You complaining on the internet won't change a damn, and I don't give a damn about it.

Yes, there have been legal judgments... Doesn't make them right. :)

They're not random people on the internet, hence they may be wrong

Windows Tax Shot Down In Italy

paulatz Re:What about other devices? (421 comments)

BTW, you CAN buy a Dell without Windows, you just have to order it that way, their business division sells them.

They only sell a few modem without operating systems, i.e. no laptops in europe.

FYI taxes are always included in the price in Europe. Free's 20€ are actually 19.99€ that get out of your pocket.

When will large-scale IPv6 deployment happen?

paulatz Re:Fuck IPv6 (305 comments)

Seriously, with NAT, you have a possibility of 64512 unique devices behind the router, you can port-forward any of them, and even use UPNP should you use to (not that I would).

TBH, I like the fact that my router is the only device facing the public network (security wise).

I like the fact that you think it provides any security. Just ask yourself this question: when I contact a server outside the NAT, how does it get back to me? Is there any special reason that prevents someone else to do the same?

Wayland 1.5 Released

I've had to remote Firefox too,

You're doing it wrong! Just set up an ssh tunnel and tell firefox to use it as sock proxy. This works seamlessly

Ubuntu Linux 14.04 LTS Trusty Tahr Released

paulatz Re:Code names (179 comments)

Quick - when was Hardy Herring? Did you have to go look?

I completely agree with this. I'm do not use Ubuntu regularly, but sometimes I have to help people who do. I do not know the names by hearth, I guess I can just do cat /etc/issue and get it? Nope! There is only says the version number. Ok, no problem, I'll google the number. No way, in the support forums everybody just uses the code name. Finally I have to check on wikipedia whatever name version 12.04 has.

To be fair, there is the same exact problem with Debian. It is true that Debian only has had like 6 releases since the beginning of time, but it adds the extra complexity layer of calling them stable, unstable and testing. So, let's check if debian 5.0 support this.. no information. Let's try if google for lenny returns something? Nope. Ok, let's see google for "debian stable" then manually check every result to see if it was published between 2009 and 2011.

Ask The Linux Foundation's Executive Director Jim Zemlin What You Will

paulatz Re:Uniformity b/w distros (58 comments)

Can the Linux Foundation set up a definition where things just have to be in certain locations, regardless of distro, and certain commands that just have to work, regardless of distro?

Satya Nadella Named Microsoft CEO

paulatz Re:NOOOOOOOOO (293 comments)

If you think that zero is Egyptian, than why not claim it is prehistorical? Indeed the first cave men already had the concept of nothing, zero wife, zero food but zero lions in sight. The Egyptian zero is "just" a reference on a distance scale; it marks the transition from zero meaning "nothing" to zero meaning "the reference"; great stuff but not yet there.

The digit zero, used in positional notation, is indeed Indian, as you correctly but partially quoted later. It is a fundamental advancement as it makes algebraic computation dramatically easier. Its actually what allows the transition from geometry-based mathematics, like in ancient Greece, to algebra-based mathematics, like in the Arabic world during the middle ages. And then all the way down to the Turing machine, which performs a minimal set of read/save and algebraic operation necessary to solve any decidable problem.

Sorry, the number zero was an created 3700 years ago, and not in India.

Sorry, but you're wrong, racist, and fat.

ZERO!

Like, literally, the number zero. Half of the binary digits where invented in India. The other half in Africa.

Former Dev Gives Gloomy Outlook On Linux Support For the Opera Browser

paulatz Re:Actually paid for this once... (181 comments)

and then they offered server side "rendering"

LOL, what was the idea behind that? Did it parse the html/javascript code and send you an animated .gif as a screenbuffer or what?

There are actually two features.

The first is actual server side rendering, where they would send you some kind of compressed image. This method is used by Opera Mini for android, "feature" nokia phones and I guess even iphones.

The other feature is a server side filtering, at the moment its called on the road mode, it strips unnecessary parts of the page (html comments, unused javascript..) and compress it, then it also recode embedded images with higher compression level. This feature s available on all platforms.

Fedora 20 Released

paulatz Re:It's a meta joke (147 comments)

If you want to know what you're installing you cannot know how long it ill take.

More accurately: The uncertainty of installation time multiplied by the uncertain of package content is greater than or equal to the reduced Plank constant.
