This looks impressive, but I think an SVG image would be just enough and the right tool for single-color logos like those of Adobe, Twitter and Nike.

For Nike it will be just a background declaration, the curve with Bezier parameters and the foreground color. It will be much more compact and be able to scale.

And just as much cross-browser as CSS, which means not totally cross-browser. Your logos are broken in Opera and IE, for example.

I understand it takes much effort and expertize, but it's not the right tool for drawing images. You could do this by just exploring the UTF characters table and positioning differently colored characters near each other to make an image. But the fastest way to draw a vertored shape in a browser is still SVG.
Seems very reasonable from Ericsson's point of view, and was probably just a matter of time.

Sony Ericsson has moved away from using the hardware platforms delevoped by ST-Ericsson (since they have been too late to market) and using Qualcom like many other Android handset makers which means there's little point in keeping them in their portfolio. Also, with the standardized features of all Android phones, it won't help in selling new end-to-end network features to operators either since most handsets support the same features. Sony Ericsson has been quite late in launching new features (still no LTE phones for example), so Ericsson was already relying on other partners to support deals with operators.

Hopefully this makes Ericsson focus on their competency (networks) and allows Sony to do something interesting with the mobile phone branch.
Ask HN: Which is better. A server farm somewhere hot or somewhere cold?
Two recent articles caught my eye today. Both about new server farms being built/upgraded.

One is somewhere hot (North Carolina, Apple) [1]

The other is somewhere cold (Sweden, Facebook) [2]

Hot, (assuming more solar energy available) benefits are increased power from a solar plant but the farm requires more cooling. Cold, requires less cooling therefore less energy.

It's interesting [to me at least] because it raises the question of efficiency. i.e. do you build something that requires loads of power - but who cares 'cos we got tonnes of renewable energy... or do you try an require a lot less energy even though hydroelectric is not damaging to the environment the more you produce.

Of course - FB just probably needs a server farm close to North Europe users. Still, it's a big eco-plus in my book.
This has as much to do with using "stranded" hydropower up in the north as it does with taking advantage of low ambient temperatures for free air cooling.

That is probably technically difficult from any significant distance, because tiny differences in air temperature slightly alter the refractive index, and add random error to your measured brightness that most likely would dwarf the tiny fluctuations in light output.

On top of that, light output is a quantum phenomena, and this complicates any analysis from a significant distance.

For example, suppose that there is a 630 nm, 2 mA average red LED attached to the computer, with a clock speed of 1 GHz. Each photon has 6.6260695729E-34 * 299792458 / 630E-9 = 3.153088387521748e-19 J of energy, so the device emits 6.342987427548621e15 photons per second, or 6.342987427548621e6 per clock cycle. Assuming those photons are radiated in a perfect semisphere, and a 15cm telescope aperture at a distance of 100m, the number of photons per clock cycle is 6.342987427548621e6 * pi0.15^2 / (2pi*(100)^2) = 7.14 photons / clock-cycle.

From such a small number of photons, trying to detect a <0.002% change in voltage seems to be infeasible unless the attacker can make the computer repeat the exact same sequence of operations with predictable timing enough for an averaging procedure.

Obviously, if the attacker can get closer or use a massive telescope aperture, the attack might be more feasible.
Comparing the two is a bit like comparing Thomas Paine to Thomas Edison.

Stallman created a movement. A movement that largely predicted the ways technology and society interact. I think in 100 years people will still using the GPL. I can't say that about the iPod.
TVs are different, because with a TV you don't really care about how it looks.

Phones on the other hand ARE also fashion gadgets.

For this reason alone, there are companies out there that are dressing normal phones in gold and precious stones. It's crazy, but it goes to show that customers do want to set themselves apart.
Don't they already use true noise made by your computer hardware (analog)? For example fine measurements of fan speed, fluctuations in input power, and so on.

Show HN: Hot & Cold game in mobile web browser
After reading Mark Pilgrims "Dive into HTML5" (currently available at http://diveintohtml5.info) I wanted to play a little with the new API features. I started with Geolocation API, which actually is not a part of HTML5 specification. My main goal was to check if browser geolocation performance is sufficient to work in realtime tracking applications.
So I created this simple game, to be used in web browsers on mobile devices.

Well, the Linux kernel is GPL.
The point I'd make is that you still get BlackBerry style android phones, and crazy folding ones and many other form factors.

If you only compare a single blackberry-style phone from the pre-iPhone era and one slab phone (which doesn't look particularly iPhoney-except in relation to the hardware keyboard phone) then you'll make a good rhetorical point for people who already believe that Android is an iPhone clone. I don't know if you'll convince anyone else.

There was a similar, older comparison which resized the phones and kept hardware keyboards shut, which again, seems a bit disingenuous if the point is to show similarity.

Honestly, having experimented with various devices, I'm not sure there's a productive development environment out there with a keyboard. A tablet in a keyboard dock may well do the job, but if the keyboard is required for useful work don't we then have a de facto netbook?

Which is what I use, incidentally. Currently 10" but has been 9" before. Running Visual Studio 2010 for the zoomable IDE, and I find it makes a very nice development platform. Highly recommended for such use.

> Basically OS X destroyed Linux's chances on dominating the future desktop.

Yeah, because the constant feuds within the Linux community, the failure to settle on a common desktop platform, the crowd of "I-want-to-write-yet-another-irc-client" devs, and the utter lack of appreciation for end-user needs all have nothing to do with it.

What Stallman in particular and the Linux community in general fails to understand is that a broken or badly designed software for which you have the source is more of a prison to the user than a well-made, closed source one.

Before you flame me, I've been part of the Linux community from 1995 to 2008, and I dare say I was more than an annecdotic contributor. I still support the idea of free software, but community development simply doesn't scale.

I actually like "keep its hardwares cold". Point taken, that this is not the most rigorously edited article.
Cooling will be achieved by placing a VLS (Very Large Stetson) over the data center.
If your data centre uses less energy than your renewable energy source, then you can push the excess out onto the grid. Similarly, if you use more than you can produce, you have to pull the deficit from the grid. Either way, the less energy you use, the more energy has to be generated elsewhere. So energy efficiency still matters.

Against that, there are transmission losses. If your data centre in a cold dark place is powered by a solar array in a hot sunny place, you need less energy to spend on cooling, but you have less energy to spend because more energy will be lost in transmission. I don't know how they balance out.

(And if you have enough clients in the hot place who want low latency, it makes sense to put the data centre in the hot place even if it's less energy efficient.)
But they did have to cut features right? That's the whole point of the video you linked to (which I can't view for some reason). So they got some things, but didn't get others. Just like the Nexus One doesn't get the ICS launcher, clock widget, support for dual-cores & NFC chips (that it doesn't even have) or the new font but does get the very latest improvements to Google Maps, Youtube, and all these Google provided apps (most of which are available to 97.5% of Androids that visit the market, Maps to 98.9%, Google Translate 100% as it supports Android 1.5+):

https://market.android.com/developer?pub=Google+Inc.

And if the past is any guide, there will be newer and better apps added to that list shortly after they are previewed in the latest Android release, sometimes announced with very strict requirements but then later relaxed as features are backported e.g. the new Market that at first was 2.2+ only:

This is huge news. The ARM server market is going to get jump-started by this. Plus, it gives ARM a lot of credibility in the market now. I assume these servers will use Cortex A15.

Sadly, the entertainment industry is much larger and has a lot more money than the tech industry. And yes, Google, Facebook and other large companies are stepping up - they're the reason most people are even aware of the issues...
yes yes, a thousand times yes. There is some serious misinformation in this thread though. Apple has allow interpreters on the phone for a while, and the remaining restriction is that you can't download code or bring code in through the app document directory. This app breaks neither of these restrictions. In fact, there have been other lua interpreters running on the ios for a while now, see: http://www.mobileappsystems.com/products/iluabox

The difference with this app is that the ide is really a labor of love, and it is super fun to code in. Not that iLuaBox isn't, but all of the little features for tweaking colors and editing sprites are brilliant. The graphics and audio engine don't hurt either.

For those complaining that there isn't a companion engine that you can take the code out of codify and release actual games, you should take a look a corona. The api in codify is not so big that you wouldn't be able to clone anything that you made in it to another platform relatively easily. I do agree that there should be more lua based gl engines for iphone though. I am working on one, but as of yet it is totally for my own use, but only by virtue of the fact that it doesn't come with nice build scripts.

The other thing that some commenters miss is that you can use copy and paste in this app. That will open the gates to sharing code, it is as easy as: select all, copy, switch to safari, go to pastebin, send link to someone else. I suspect that some of the time the app spent in approval was them thinking about that.

On the Glass-Steagal reinstatement, even though you did not offer any argument against it except to repeat McCardle's claim that people don't know what they're talking about, I'll offer an argument for it even though I admit I'm not some financial expert.

Glass-Steagall meant that investment banks had to entice investors to put their money into the system. The repeal allowed investment banks to raid and leverage depositors accounts. This introduces systemic risk because depositors unlike investors view their savings as a demand account and receive little interest because of that. Their money is basically cheap for the banks to get and the depositors always expect that money to be there. Investors expect a return that justifies the risk that they are entering into together with the investment bank/brokerage. Their money is relatively expensive to banks to get because the investor knows that money could disappear. Once banks could treat all those deposits as levergable funds for risky investments they didn't have to entice the expensive investment money or use caution in their investments (FDIC will pick up the losses). So with the repeal of G-S, brokerages suddenly had access to huge piles of FDIC insured money and all that money needed some place to go... and we've coincidentally had 2 major bubbles since. First the dotcoms, then mbs's and other related cdo's and now Treasuries. Break up the banks, make the investment houses have to make sensible bets (not 50:1 levers) that return better returns for investors and force banks to make terribly boring investments to return terribly boring rates to depositors and we have the beginnings of the return of sanity in banking. Without that, we will continue to inflate bubbles, pay bonuses and then bailout losses after the unavoidable asset deflation.

Here is another, more informed than me, argument for reinstatement http://moneywatch.bnet.com/economic-news/blog/maximum-utilit... "However, whether the elimination of the Glass-Steagall act caused the present crisis is the wrong question to ask. To determine the value of reinstating a similar rule, the question is whether the elimination of the Glass-Steagall act made the system more vulnerable to crashes. When the question is phrased in this way, it’s clear that it has made the system more vulnerable for the reasons outlined above.

It should have been obvious for everyone right away that either Amazon was not selling excess capacity or depending on AWS would have been a very bad idea.

If Amazon was selling excess capacity, care to guess what would have happened to peoples services come the christmas rush, or any other crunch time for Amazon?

AWS have always been expensive for capacity you need most of the time compared to renting dedicated capacity elsewhere, as you're not only paying for the capacity, but for enough excess capacity for Amazon not to run into the PR disaster of not being able to handle requests for new instances.

The numbers and plain logic just never matched the perception of Amazon selling excess capacity.

The most amazing thing about AWS was how Amazon managed to get people to see it as the most amazing thing to ever happen for hosting and create the perception that you somehow paid for less, when for most typical web hosting scenarios you pay more for a service that is pretty much promised to be less reliable.

You can't force the minimum wage up any more than you can push on a piece of string. While you can certainly change legislation to make the minimum wage a set value, there will be offsetting measures felt elsewhere, usually an increase in unemployment and a general drop in living standards for all. You can't force someone to employ you anymore than you can force someone to be your friend.

Once houses have finished correcting lots of people will be able to afford them. Housing affordability is headed towards the best it's ever been.

I agree that things are bad, but going down the road of trying to force a solution by means of restrictions, price controls and regulations will only make the problem worse.

As I've posted in the past, places like Detroit should be cordoned off and turned into special economic zones like Hong Kong is to China. There should be a very low tax rate, no trade restrictions with other countries, and many other regulations, taxes and boondoggles dropped. There should be no (or very low, say 3%, for Military use) federal taxes and in turn they should receive no handouts or participate in any programs from the Federal government.

Do that I can guarantee that in 10 years the place will be booming, employment will be high and things will be moving in the right direction. With somewhere like Detroit, it's time people started thinking outside the box and experimenting with some rollback of the last 100 years of policy.

It depends what you want to show, in this case I was showing the size difference between a file unencrypted and encrypted. An all-zeros file has nearly no randomness, so it compressed very well. Then I show that somehow the encryption process takes away this lack of randomness, and leaves a file almost incompressible. I'm really just increasing the scale to make it more 'dramatic'.

If I happened to be showing how compressed codecs like jpeg, mp3 or h264 weren't compressible, I would definitely pick something more like an actual text file.

I'm not usually one to get into eco debates, but can anyone who's knowledgeable in the field tell me whether it's a good idea to build heat plants in places where they shouldn't be - I mean long term?

The way I see it now is that placing a structure which releases hundreds (thousands?) of kilowatts of heat in the ocean, rivers or arctic ice (as an example) is bad for the ecology - once the place heats up (and it will), it's not going to cool down by itself. This has the potential to rise overall global temperature if enough companies do this. Am I right or way off?
