I thought that the cost of bringing the satellite into space exceeds the cost of the actual hardware a lot. Does it really make sense to harvest the parts? I'd like to see numbers.
It's not so simple, I don't think that your analogy is entirely correct. The developments required for the introduction of first commercial microprocessor were vast and most of that knowledge is still relevant or new ideas were built upon it. We already have most of the technological and scientifc knowledge so the leap needed to manufacture graphene chip is much smaller than in case of silicon.
Essentialy this guy has executed a hoax to test how much media attention he can get. And he's proud of it. Well maybe he wasn't aware of it being a hoax but his claim vs. actual "outcome" certainly seem like one.
The project is completely, utterly useless. Proves nothing, demonstrates nothing, it just does nothing. I tried very hard but can't find any value in it whatsoever.
I would be ashamed to advertise myself with something like this unless I were 14 and just started programming.
I skimmed through the article once more. It mentions that some security researchers use tools like arduino. Then there is a lengthy description of the new Arduino Due with no indication as to how you could use it (or how it is being used to such extent) to exploit hardware*. And finally author concludes that developers should test their hardware cause now (supposedly because of arduino due) everyone can try and exploit it.
Upon closer examination I conclude there is absolutely no thesis stated in the article. It is a brainless drone-written piece of trash that is barely coherent.
* I am sure that you could use arduino UNO to poke around some types of industrial hardware. I don't see how the coming of DUE is relevant here.
DISCLAIMER I, for one, am a big fan of arduino and other platforms that enable average basement joe to play with real, physical hardware.
There is no justification in the article for the thesis it states so boldly in its title, ergo, the article is completely worthless. Reads like an advertisement. Slow news day?
As far as the alternatives are concerned. Usually only LiPoly batteries are used in smartphones, etc. because other chemistries require sturdy metal casing (which is relatively HEAVY) and are hard to fit effectively in a thin, rectangular factor.
LiFePO4 lasts longer in terms of cycles, but has half the energy density of standard LiIon (and lower nominal voltage), I think that's why you don't see it in appliances. But it's an interesting battery - it has very low internal resistance which means you can pull a LOT of current from it what makes it great for certain applications (intermittent usage, high peak-current). What's more the LiFePO4 chemistry is safe, it won't explode in your face because of a short.
Another alternative are LiMn cells, they have the same voltage as ordinary LiIon (can be used as drop-in replacement), slightly lower energy density, can supply high currents and last twice (or maybe more?) as long. From what I hear this chemistry is not feasible for small batteries (in terms of volume). Oh and they rarely explode.
There is one problem with this. Yes, you can prototype on arduino very well, but suppose you tested everything and want to deploy your project on a dedicated board. I can't see hobbysts soldering QFP packages and making 3+ layer PCBs at home somehow. Compare that to soldering a DIP socket on a possibly one-sided board.
Maybe one project - one arduino isn't a problem for some. For me it's way to pricey and not a good solution to add a quite big board with a lot of redundant circuitry to every project.
Next thing - what about the mods, arduino forks, fully compatible alternatives? There won't be so many now.
What about the people who make the bike? Did they take into account how much they eat?
I am surprised they didn't count in the CO2 we exhale. Imagine that - living is not zero emission, let's commit a group suicide in the name of our mother earth.
I don't care if facebook is taken down. Yes I use it, but any part of my life doesn't depend on it. In case it would have been taken down, I would move to the Next Big Thing or just forget it. But I would really, really like to see a high-profile target taken down. Just for the sheer fun of it. Just to see it can be done by script kiddies. I imagine an event of this scale would really rise awareness about security on the web. Keep building sand castles...
As far as the method is concerned I suspect that the only method to do it, would be to publish some incriminating evidence involving facebook, spinning up a media scandal, but probably not prosecution (how do you call it - 'fruit of the poisonous tree'?).
There will always be something that doesn't work as it should or as you would like it to be. KDE 4 is a stable, solid desktop environment. I used KDE as my day-to-day working dekstop since 3.x. I jumped the wagon when they ironed out showstoppers in SC4 and don't look back.
BTW I wonder why there is so much complaining about KDE when it comes to some minor features? Such scale is unseen in windows world. Maybe windows users don't complain so much because ms doesn't care about fixing and improving things anyway? Here you can discuss and have things fixed or even redesigned in a matter of weeks or months.
Make them shorter so nobody will play long enough to notice how crappy and not engaging the gameplay is.
In ten years AAA games will be shiny, useless objects of desire. Buy it, launch it once or twice to see the breath-taking graphics, stuff the box on your shelf. Now you can stare at your precious shrine made of game-boxes. Don't play it, just own it.
Benchmark a very well known and supported OS vs. an obscure OS under VM - brilliant idea. Not that the VM will probably falsify the results completely.
Don't they know that VMs contain OS-specific hacks improving performance? At least VirtualBox last time I checked.
IMHO article is worthless. Oh and I would love to see a fresh alternative kernel with linux userland compatibility but I doubt HURD will step up to this task.
From what I've read I gather that Lamo has got some serious psychological issues. That business with Manning only confirms that the guy doesn't know who he is.
Well, I don't see your point. If the topic is valid and the blog post is interesting then what's wrong. Why dismiss something just because 'random guy' wrote it?
(Disclaimer: I'm not talking about this posting in particular)
I didn't read TFS thoroughly enough - KDM (which is the login manager) integrates with grub2. Probably it means that you can do some fancy stuff like tell it to reboot to freebsd, windows or osx (if you have multi boot).

Why would you need alpha with lossy compression? I can't imagine how terribly it would look.

+1 for Archer reference
No more downloading putty!
From what I see ncurses apps work great too.

Forget the tech demo RAGE is.

Yeah, that's exactly what we need. More rules, more books describing how to do *doing* something. Meta-meta-meta-everything...
And more companies that take a methodology which has quite sensible premises and transform it to a paper-pushing-based freak-child.

25USD? Probably only in the USA. I guess in Poland the price of the A/B models will be something like 75/100USD... Hooray global market!

Enough of this BS.

Since when we measure significance of a breach by the raw amount of data?

Great read about lamo. There was a lot more, but I can't seem to find it.
From what I've read I gather that Lamo has got some serious psychological issues. That business with Manning only confirms that the guy doesn't know who he is.

I read the TFS twice and WTF is it all about? No wasting time to read the TFA then.
I didn't read TFS thoroughly enough - KDM (which is the login manager) integrates with grub2. Probably it means that you can do some fancy stuff like tell it to reboot to freebsd, windows or osx (if you have multi boot).
