Ask Slashdot: Best Way To Store Data In Hard Copy?

Capitaine How do you backup your backup program? (329 comments)

How do you backup your backup program? I you use a special encryption and coding (e.g. barcode) program, you will need it in 10, 20, 30 years when you disaster actually happens. How do you make sure that the program you need to recover you data still is available?
Their is few doubts that OCR will still be available. However, barcodes and LUKS might be obsolete...

French Intelligence Agency Forces Removal of Wikipedia Entry

Capitaine Re:Whut? (179 comments)

As an employee, you are not responsible for everything your company does. Neither in the USA nor in France. The threats addressed to the administrator were mearly intimidation and had not any legal base. Twitter has many lawyers who would have defeated this trap. The admin was isolated.

Crowd Funding For Crank Physics

Capitaine Actually, it works ! (379 comments)

The guy uploaded the analysis from a professor of Florida University which notes improvements over regular cranks... However, not the ones claimed in the video.
What is nice is that the first paragraph contradicts the video : "As far as mechanical advantages is concerned, the angle crank does not offer any more than the traditional straight-link crank[...]". The Pr sees the higher momentum of inertia as beneficial for pedalling as well as the bending mode, concluding that those two properties are obviously not intended.

As far as I am concerned I am not quite sure I would like to have more momentum of inertia to overcome and I find the effective improvement from flexure mode dubious.

The Scourge of Error Handling

Capitaine Re:The third option (536 comments)

My work implies writing aeronautical software specifications. In order to facilitate FAA/EASA certification of the system, we are required to stick to the KISS principle. Data validity checks are done almost everywhere, but we are asked to design the logics so that they do not need to use these data validity statuses. Degraded mode is done through the use of failsafe values. The consumer of a data do not need to know the status of the producer. The whole system is designed so that it works and is robust with minimal use of alternate logics.

This principle works well with dataflow oriented program and might be adaptable to other domains.

Toshiba Pursues Copyright Claim Against Laptop Manual Site

Capitaine Re:Thanks, Toshiba (crosses off purchase list) (268 comments)

Because Toshiba sells repairs. Or at least sells nice "Toshiba-authorised" stickers to repair-shop which in exchange expect advantages over non authorised shops. It's actually written in the middle of TFA citing Toshiba lawyers:
“The manuals are only available to Toshiba authorised service providers under strict confidentiality agreements.” “It is not our company policy to grant authorisation for the use or reproduction of Toshiba manuals to anyone who is not an authorised Toshiba service provider.”

Ask Slashdot: What Stands In the Way of a Truly Solar-Powered Airliner?

Capitaine Re:Um... (590 comments)

Jet engines are quite inefficient. The main problem being power I would start with props.
To get an idea of the power needed, just take a regional aircraft, for example an ATR equiped with two PW100. That makes roughly 7000kW of energy provided to propellers. Lets suppose you have 100%-efficient electrical motors, and let aside aircraft internal consumption.
Now this paper suggest that high density power solar cells provides about 1kW/sqm. The only challenge is to find 7000sqm of surface exposed to the sun on a 22m long and 24m wide aircraft.

So far, the only electrical plane that I have been able to see were ultra light aircraft which could barely support they own weight and a pilot. Still a long way until commercial exploitation.

Industrial Control Software Easily Hackable

Capitaine Re:Not such a bad idea... (194 comments)

Security is not in requirement specification, why would they implement it ?

"- Boss, I got an idea. We could implement two-factor authentication, full AES encryption of network data and D-H key exchange in our industrial software. Nerds will love it. It would cost x k$ (with x > 0).
- Hum, no. And gtfo of here."

FAA Permits American Airlines To Use iPads In Cockpit "In All Phases of Flight"

Capitaine Re:How about just an iPhone and save even more? (372 comments)

I guess Apple will just start to comply to all standards concerning aeronautical grade software and hardware and perform common cause analysis to avoid this from happening. I'm sure Apple is concerned with our safety.

Know What Time It Is? Your Medical Device Doesn't

But if you worked for the CERN and used your phone to measure neutrinos travel time (everyday life application), you would have biased results.

Know What Time It Is? Your Medical Device Doesn't

Capitaine Re:NTP and hospitals (290 comments)

Medical equipments have to cope with safety issues. I would not be surprised if it would be more important for a medical equipment to have a stable clock than an accurate one. Moreover, I guess most hospitals would prefer to set manually the time on each clock than having to set up and maintain a NTP system for non critical applications.

Despite Drop In Piracy, French Music Industry Still In Decline

Capitaine Re:Simple Answer: (272 comments)

Actually, the "Hadopi" only monitors P2P trackers. Most French now use DDL. If you look at their hadopi's graphs, you'll see that sales skyrocketed since Megaupload seizure. Just wait a year and you'll see that MU old competitors will just have taken its market shares.
For the topic, you may know Gojira.

French President Proposes Jail For Terrorist Website Visitors

Capitaine Re:Attacking the soul of France... (402 comments)

Nicolas Sarkozy has been elected thanks to far right supporters votes. Now new elections are coming and he tries again the magical recipe which got him elected. During his whole mandate, Nicolas Sarkozy tried to keep this support in order to minimize the threat of the main far right party, the Front National. However, this policy eventually got him criticism from liberals of his own party.

Since the retirement of its old leader, the Front National is led by the old leader's daughter, Marine Le Pen, who tries to establish its party as a "normal party" and get rid of racism accusations. This policy seems to work and she gathers more and more official support... from people who voted Nicolas Sarkozy. The actual president has therefore to fight for far right votes without loosing to much votes from center-right to his socialist opponent. Moreover, the president Sarkozy has a long history of fight for Internet regulation, pleading for a "civilised Internet". Several laws he passed eventually got deemed unconstitutional or contrary to the European Convention on Human Right.

Finally, Sarkozy has always been very communication and PR oriented. He always reacted very fast (1 day reaction time, much better than French administration) to any event with big declarations about new laws that are to be applied "very soon". This last proposal just doesn't represent anything. It could not pass the constitutional court and cannot even be voted. French presidents start their mandates directly after their election and the legislative session of his current mandate has already ended. That's nothing but communication.

Campaign Urges People To Send MPAA and RIAA Copied Currency

Capitaine Re:Genius. (413 comments)

MPAA and RIAA often argue that piracy is theft. The whole point of this campaign is to illustrate the difference between piracy and theft by providing an example of object which copy is worthless while theft isn't.

For Sale: Internet Spying Business Developed For Gaddafi

Capitaine Re:I'm sure someone will find a use for it (36 comments)

Well, to be jailed, they should have done something illegal. Being French, I know the French government sometime take liberties with the rule of law but I would prefer them to avoid it. The bid was backed by French government and was aimed at "fight against terror". Being unethical doesn't make it illegal. The problem comes more from politicians than arms dealers.

If You're Fat, Broke, and Smoking, Blame Language

Capitaine Re:I'd love to see some numbers on this... (297 comments)

TFA explains that English and Spanish are strong-FTR languages. French tenses being close to Spanish ones, I guess that French is also classified as strong-FTR. Therefore, you cannot conclude that it is due to the difference of languages, both being strong-FTR languages.

EU ACTA Chief Resigns

Capitaine Re:Partially wrong (253 comments)

Went on respective websites, searched in the main page, International, Tech and Economy pages. I guess that searching for ACTA means you already know it was signed, confirming what the original poster wrote. I must however admit I overlooked your first link in my research.

Just checked out the 3 major French (Le Monde, Liberation, Le Figaro) and German (Frankfurter Algemein, Süddeutscher Zeitung, Die Welt) newspaper website. No trace of the ACTA. Nothing more in economical newspapers. Your words are safe.

The New Transparency of War and Lethality of Hatred

Capitaine Re:Bogus premise (591 comments)

The problem comes mainly from the differences between real war and what government sells you/media shows you. War doesn't mean bringing peace with happy soldiers, impressive fireworks and no civil casualties. Yeah war is hating and killing, mutilating. People often forget that. So when an image of real war just gets out, it shocks the people who though we fought with an ethic of war. I guess this video is actually quite mild.
