Examining the User-Reported Issues With Upgrading From GCC 4.7 To 4.8
Not true. Check this out: CompCert, a formally proven C compiler (i.e. 100% perfect).
And you can use it today, for free (GPL), on real programs.
Ask Slashdot: Practical Bitrot Detection For Backups?
CrashPlan could help you a lot. First, CrashPlan is a backup system, so it makes and manages a copy of your data, including every version of every file. CrashPlan addresses the bitrot problem on their side by running their own checksums on the stored files : if they detect an issue with a stored file, they will replace it with the original version, still stored on their computer. If some files get corrupted on your computer, you can restore them from CrashPlan, but you will need something on your side to tell you that something went wrong. Now, even if you realize that the file is corrupted years after it happens, you can still recover the previous non-corrupted version from CrashPlan.
Now, 2TB is a bit much to store on CrashPlan's cloud : unless you have a very fast connection (at least 100MB) it's going to take you a while to upload your data. The solution is to run your own CrashPlan PRO Enterprise server onsite (with periodical offsite backups of course). Don't be fooled by the name, it's pretty easy to set up and administer, and the licenses are fairly affordable (75$/user/year).
I've supporting CrashPlan PRO Enterprise in my company for 3 years, with 25 clients and about 1TB of data. While I'm not super-happy with the way the Code42 people run their CrashPlan business, the tech is solid. I'm kind of thinking that other backup systems work in similar ways.
Now, I hope that you'll excuse me for asking this question, but which kind of crappy file systems and hard drives are you using that generate significant levels of "bitrot" in files which are basically just sitting there?
In France, a Showcase of What Can Go Wrong With Online Voting
A few facts :
- It's only a primary for the Paris mayoral election next year, i.e. not a national election.
- The journalists shown that it was really to vote as someone else if you knew a couple of easily and legally obtained piece of information about them i.e. no hacking involved. However, so far there's no indications that fraud is actually taking place.
- The same party is having a primary in Lyon as well, but they are using a traditional paper ballot, and so far it seems to be going pretty well.
OK, so electronic ballots are proved to be less "secure" than paper ballots, again. The UMP is proved to be technologically illiterate, again. Yawn.
Iran Unveils Its Own Stealth Fighter Jet, the Qaher F-313
Not sure whether this is a hoax or not, but the pictures seems to show a model, not a real plane. Have a look at the cockpit : http://edge.liveleak.com/80281E/s/s/19/media19/2013/Feb/2/LiveLeak-dot-com-4347f2b9fa55-f313_17_preview.jpg?d5e8cc8eccfb6039332f41f6249e92b06c91b4db65f5e99818bad29f444cd3d1ca14&ec_rate=200
I don't know anything about jet fighters, but I can recognize a Thrustmaster Mark II joystick stuck to a pole. And the material on the border of the cabin definitely looks like duct tape. And the canopy does not seem to lock into anything. And so on.
The Case That Apple Should Buy Nokia
Let's say Apple buy Nokia for those reasons (Maps, patents and Fuck Microsoft). Apple now has to fire 95% of the company (they only keep the IP lawyers and the mapheads). Nokia has 122,000 employees, many of them in Europe were they cannot be fired easily. That's 116,000 pink slips. A $100000 redundancy payment per person seems about right ("Apple is loaded"). That's about $12 billions. Combine that with Nokia's market cap (about $10bn) and the price rises to $22bn. I guess Apple could technically afford it, but the damage to their image could cost them even more.
Why You Shouldn't Panic About Closed Source MySQL Extensions
In VirtualBox v4.0, Oracle released the core as an open-source projet and the proprietary extensions as a plug-in. This proprietary extension is free for home use but commercial users must by a licence. The extension is not 100% necessary but does provides some very useful features, such as being able to connect to the "console" of a headless VM. Cool right?
Well, not really. There is at the moment no way to actually buy such a licence from Oracle, so all the people using VirtualBox v4.0 with this extension in a business are technically out of compliance.
VirtualBox is cool, but they really need some leadership from Oracle.
GPS Tracking of State Worker Raises Privacy Issues
The first Selsius phone was released in November 1997 and the company was acquired by Cisco in November 1998. That's a bit short to create much legacy code. Plus I think lots of the current IP phones they sell actually came from Linksys...

Man With 10 Million Air Miles Gets Plane Named After Him
There's about 300km from London to Amsterdam. However, due to this little thing called the North Sea, the trip on a high-speed train (a real one) takes a bit more than 4 hours (if you get your connection right between the Thalys and the Eurostar in Brussels). Otherwise it takes about 5 hours.
But of course the train will take you from Amsterdam Centraal to London Victoria, not from Schiphol to Hearthrow, Luton, or, God forbid, Gatwick.
So overall, I'm not sure which trip is going to release the largest amount of CO2. Probably the plane one, cause the Eurostar runs mainly on nuclear power...

Why did you leave a position as a "star programmer" to move into network administration? Why restart at the bottom of the ladder?
Ask Slashdot: How Do You File Paper Documents At Home?
I just scan everything. And I mean everything.
The Fujitsu S1500M is a great piece of kit, but pretty expensive. But it can scan and OCR big folders in a manner of minutes. And the software does not suck, which is much more than can be said about the software that usually comes with flatbed scanners. I just hope it could remove the staples as well.
All those scans are just dumped in one big folder. Then Spotlight makes it a breeze to find something. Anectodal evidence shows that it works on Windows too.
I still keep the original paper version, in one big paper folder. Once a year I review the content, throw away the outdated files and move the rest to long-term storage.
Now, if a provider offers an electronic delivery option, I usually pick that instead, if the provider is reliable.
What Kinect Could Be, But Probably Won't

Book Review: R Graphs Cookbook
Or any other spreadsheet program.
Now of course I admit that Excel is probably not as flexible as R. However, unless your job is to produce stunning, tailor-made graphs, a spreadsheet application will deliver results a lot faster.
No Contactless Payment System In Next iPhone
The NFC industry suffers from two bigs issues.
1. Huge installed base. There's already lots and lots of installed contactless systems : while many are supposed to follow standards, the standards are unfortunately not good enough to make sure that a NFC phone that would work in London would also work in Amsterdam.
2. Unclear business model. NFC involves too many powerful stakeholders : SIM card manufacturers, mobile phone manufacturers, service providers (banks, transportation operators), mobile telcos ... They all want a vut of the action: making them all agree on a clear business model is very difficult.
I hoped that the combined pressure and will of mighy Google and Apple would finally move things forward. Looks like the complexity of NFC defeated another big corp.
Security Strategy: From Requirements To Reality
Totally agree. This book gets great reviews because it is entertaining, but fails totally as an "guide". It will not turn anyone into a security practioner.
Regarding the author, while his heart is certainly in the right place, his research has erred a little on the sensatianalistic side ("Chip and Pin is Broken!"). I will have a look at this book, but my expectations are low.
When Rewriting an App Actually Makes Sense
... and most of them run in a controlled environment (server-side). So lots of Joel's advice is not going to apply.
Then they have the balls of comparing their move to the transition from Mac OS 9 to Mac OS X!
In the end, while their story is interesting, it adds really little value to the "Rewrite/No Rewrite" debate.
IBM Claims Breakthrough Energy-Efficient Algorithm
I'm all for energy-efficient algorithms and datacenter but this PR is nothing but green-washing. IBM's algorithm is just faster so it uses less energy. Duh.
Automatically spreading loads across datacenters in multiple locations to take advantage of local environmental conditions so you don't have to use chillers, now that's something.
After Learning Java Syntax, What Next?
Effective Java, Second Edition, by Bloch. This book is quite unique and can save you a lot of journey time as you travel the path from "beginner" to "expert". I wish it had been available when I started. Caution: it can make you grow a beard and mumble about the advantages of respecting the .equals() contract.
GSM Decryption Published
The weaknesses of this algorithm are well-known and a new version that fixes those issues has been available for a long time. Now, does anyone knows whether this new version has been deployed everywhere? Who is still relying on the older version?
BTW, the algorithm used by 3G networks is different. It is based on AES and the design is publically available.
