gardarh··on Apple Has 1,000 Engineers Working On Chips For The Post-PC Era
Let me rephrase: What is the main difference (feature wise) between the Exynos 4210 and A5? What technical backing does their marketing have (9x better this and 100% faster that).

Samsung is pretty explicit about what their SoC contains: http://www.samsung.com/global/business/semiconductor/product... - well they have to, opposed to Apple they're selling the chip seperately.

Sometimes I think the hype around Apple's A4/A5 chips is a bit much. Does anyone know if these chips are significantly different from e.g. Samsung's Exynos chips or for that matter any other chip on this list: http://en.wikipedia.org/wiki/ARM_Cortex-A9_MPCore ?
gardarh··on Why all HDMI cables are the same
I don't feel very confident about the article after reading the following: "Before sending the signal out via the HDMI output, the 1s and 0s are rearranged to minimize how many transitions there are. So instead of 10101010, the transmission may look like 11110000. If you really like math, how it does this is cool [wikipedia link to 8b/10b encoding] ..."

It's the other way around, the encoding makes sure there is a bit transition every now and then (details in wiki article); this is done in order to preserve the clock in the signal.

When someone writes an article on such a technical subject and messes up a technicality it makes me wonder whether there are more serious factual errors in there.

I agree with his point though, my $10 HDMI cable works perfectly :)

gardarh··on What's New in Google Chrome 12?
Whoops, huge misunderstanding. Apparently this is natively supported by the print dialog in Mac OS X too. I don't usually use Macs but I do now so I thought this was a novelty.

However the print/save feature mentioned in TFA only applies to PDF documents... It doesn't allow you to directly save webpages as PDFs which was what I thought.

Nevertheless it's not possible to save webpages to pdf natively on Windows without software printers such as pdfcreator. That hasn't changed... but would be a nice feature :)

Finally! A feature so blindingly obvious but missing from all browsers: Native print to PDF
gardarh··on Detroit DIYer cooks up stronger, lighter steel, shames scientists
I didn't know there was much steel in laptops.
gardarh··on Poll: Have you had a SSD fail?
This is off topic, but isn't Dropbox essentially a backup service? Also, having your important files in git isn't really helpful unless you git repo is remotely stored and backup up.

For your sake I hope it is.

gardarh··on I hope IPv6 never catches on
The article states that offloading work from routers to clients is useless today because memory and CPU is cheaper due to Moore's law. Well guess what, traffic has increased as well.

What you must think about is "where are the bottlenecks". When you are connecting to a client on the other side of a large network (e.g. the internet) and you're not getting the same amount of bandwidth your last-mile connection should provide you with you have to ask yourself: what's keeping the speed down?

Turns out that router processing is still a bottleneck. And by delegating the mundane router work of handling packet fragments and doing checksum validation to the end terminals we are getting a much more efficient network than with IPv4. IPv6 headers are also much simpler making it easier (faster) to process with ASICs.

Stating that reducing work is useless because we work much faster now than way back when is not a good argument.

gardarh··on The silent icelandic revolution the media don't tell you about
As an Icelander I must say this article is terribly poorly written. I don't really understand what this silent revolution is about. Generally speaking, if a "revolution" isn't discussed by any media outlet and cannot be found on Google (in a country where government censorship essentially does not exist) I'd say that it isn't just silent, it simply doesn't exist.

There was never a referendum on whether banks should be recapitalized or not, they simply were recapitalized. However there was a referendum on the Icesave deal (about terms of repayments of deposits of UK/Dutch depositors into an Icelandic bank) after the president was petitioned not to agree with the parliament decision to do so. The president formally has power to do this but no president acted on it until the incumbent one in 2004 (50 years after Iceland became a sovereign state) and again in 2010 regarding the Icesave deal. This deal is actually quite different from what the Irish government is currently doing by saving its bank system, the old Icelandic banks did go into bankruptcy in 2008 have since been restarted as new institutions partly owned by the government and partly by the old bankrupt estates. The deal is about sovereign political responsibility and having a national referendum about it is quite paradoxical in my view since the end result is basically asking: Do you want to pay a great deal of money or not?

Of course the matter is more complicated than that. And is subject to lengthy spin-filled bullshit ridden politics.

About the constituent assembly: It was supposed to have already started but due to legal issues in the elections it hasn't started yet and is in a bit of a limbo. The matter of this assembly is, of course, quite political as well.

Finally, the exaggerated comments on "capitalism" and "communism" in the article are very exaggerated. Iceland has conventionally been a nordic welfare state with a strong healthcare system, public school system, etc. The atmosphere before 2008 was leaning towards the right but shifted a bit to the left after the big bank collapse. It feels to me it's shifting back to the right now as people realize that huge tax hikes aren't that great either.

Bottom line: this article is terrible, poorly written and not very informative. I don't really understand how it got any attention on HN.

gardarh··on Ask HN: What Firefox/Chrome extensions do you use?
Firefox: - Firebug (my life wouldn't be same (or sane) without it) - Remove cookies for site (one click to remove all cookies for current domain, essential when developing cookie based sites) - FireGestures (lets you go back, reload, close tabs, etc. by preconfigured right click gestures - a feature invented by Opera I believe, I can't browse without it) - AdBlockPlus (I hate to admit this but a news site I visit frequently is so loaded with flash ads that my machine almost becomes unresponsive upon visiting)

Chrome: I try to find the same extensions as for Firefox but: - Firebug lite was missing the "Net" panel last time I checked - I haven't found a gestures addon that doesn't suck - I haven't found a remove cookies for site add-on

So migrating to Chrome has been quite hard for me.

PS. Yes, I'm a web developer

You just have to love those kinds of comparisons: apparently no browser on earth has anything IE9 doesn't have.

Or wait, they wouldn't leave anything out on purpose, would they?

Support for the most widely used OS in the world perhaps?

gardarh··on One shot, once a minute catches a Tit.
The probability of an event occuring once you know it occured is, surprisingly, "very likely near 1".
gardarh··on Opera browser is much faster than a potato
This is such a beautiful slap in the face for the Chrome video. Which was pretty cool by the way :)
gardarh··on Testing A Proxy In Python
Wow, that's great! I'm going to run that script every time I'm considering opening a browser window. Perhaps this could be a Firefox add-on that would alert you every time your internet is not working... because you might not notice it otherwise and start browsing on a broken internet.
