  • Java : Oracle publie d'urgence des correctifs contre le bogue des nombres à virgule flottante

    Java : Oracle publie d'urgence des correctifs contre le bogue des nombres à virgule flottante Mise à jour du 10/02/11, par Hinault Romaric Oracle vient de publier en urgence des correctifs pour le bogue des nombres à virgule flottante dans Java. Ce bogue entraine le blocage du Runtine Java lorsque celui-ci convertit le nombre 2.2250738585072012e-308 en binaire à virgule flottante. Un bogue qui peut-être exploité à distance sans authentification. L'exploitation de cette faille peut entrainer le blocage ou le crash du Runtine Java et permettre les attaques par Déni de Service.

  • Chrome : Roi, juste pour un jour, sur PC et un dimanche d'après StatCounter

    Chrome : Roi, juste pour un jour Sur PC et un dimanche d'après StatCounter Le chiffre est symbolique et l'on ne sait pas trop s'il ne restera pas plus comme un coup de publicité pour StatCounter que comme autre chose. Mais il n'en reste pas moins que pendant une journée, sur le segment des PC de bureau, Chrome a été le navigateur numéro 1 dans le monde. [IMG]http://ftp-developpez.com/gordon-fowler/StatCounter%2018%20Mars/Globalsmall.png[/IMG] Le 18 mars donc, le navigateur de Google a été plus utilisé qu'Internet Explorer.

  • Downgrading from ubuntu 11.10 to 10.10, keeping installed programs

    - by Peter
    I recently upgraded from 10.10 to 11.04 then 11.10, and I'd like to revert back to 10.10. I understand that you cannot downgrade a version as easily as you can upgrade, and that I'll probably have to get the boot CD again and reinstall the whole thing. I know that I can keep most of my files by saving the /home directory, so 2 questions: Once I've gone back to 10.10, can I juts copy my old version of home over the freshly installed one? Is there a way to keep all of my installed programs, or some sort of way of getting the new install to automatically install them? Will I have to go through the tricky setups of things like TeX all over again? Thanks

  • How to program something with the expectation that it will work the first time?

    - by Peter Turner
    I had a friend in college who programmed something that worked the first time, that was pretty amazing. But as for me, I just fire up the debugger as soon as I finally get whatever I'm working on to compile - saves me time (kidding of course, I sometimes hold out a little bit of hope or use a lot of premeditated debug strings). What's the best way to approach the Dijkstrain ideal for our programs? -or- Is this just some sort of pie-in-the-sky old fools quest for greatness applicable only to finite tasks that no one should hope for in our professional lives because programming is just too complex?

  • What's the best way to manage error logging for exceptions?

    - by Peter Boughton
    Introduction If an error occurs on a website or system, it is of course useful to log it, and show the user a polite message with a reference code for the error. And if you have lots of systems, you don't want this information dotted around - it is good to have a single centralised place for it. At the simplest level, all that's needed is an incrementing id and a serialized dump of the error details. (And possibly the "centralised place" being an email inbox.) At the other end of the spectrum is perhaps a fully normalised database that also allows you to press a button and see a graph of errors per day, or identifying what the most common type of error on system X is, whether server A has more database connection errors than server B, and so on. What I'm referring to here is logging code-level errors/exceptions by a remote system - not "human-based" issue tracking, such as done with Jira,Trac,etc. Questions I'm looking for thoughts from developers who have used this type of system, specifically with regards to: What are essential features you couldn't do without? What are good to have features that really save you time? What features might seem a good idea, but aren't actually that useful? For example, I'd say a "show duplicates" function that identifies multiple occurrence of an error (without worrying about 'unimportant' details that might differ) is pretty essential. A button to "create an issue in [Jira/etc] for this error" sounds like a good time-saver. Just to re-iterate, what I'm after is practical experiences from people that have used such systems, preferably backed-up with why a feature is awesome/terrible. (If you're going to theorise anyway, at the very least mark your answer as such.)

  • How can I correct the paper size (A4) for Canon i560 printer for 12.04?

    - by Peter
    How can I correct the paper size (A4) for Canon i560 printer for 12.04? Canon i560-Paper size error-with printer driver for Ubuntu 12.04 Precise Pangolin offers the same problem, but the answers are not very helpful/elegant to me. Especially the second is far too imprecise and the dimensions for A4 suggested there do not seem to be correct as they do not match with any other (and correctly working) A-Size dimensions. My i560.ppd has for A4 a length of [842] which is then the width for A3 throughout the ppd-file. A3 printouts are fine (So just the way it should be). A4 are not. Cannot figure out why.

  • Les appareils sous Android seraient plus sujets aux pannes matérielles que ceux sous Windows Phone ou iOS selon WDS

    Les appareils sous Android seraient plus sujets aux pannes matérielles Que Windows Phone et iOS selon WDS Le résultat d'une étude menée par la société WDS montre que les dispositifs sous Android seraient plus victimes de pannes matérielles que les autres. L'enquête a été menée pendant un an en Europe, en Amérique du Nord, en Australie et en Afrique du Sud. Elle s'appuie sur environ 600 000 appels clients et révèle que le taux de pannes des smartphones sous Android s'élèverait à 14%. Selon WDS, les pannes matérielles les plus fréquentes sur les dispositifs Android, seraient dues à la fragmentation de la plate-forme mobile et à son adoption par des constructeurs divers. ...

  • Ubuntu 12.04 - Wakes from Suspend by itself

    - by Peter
    This problem has only just started and I don't know what has changed to cause it. I suspend my ubuntu 12.04 PC and it used to stay asleep until I hit the enter key to wake it up but for the last week or so it's been waking itself up. I've checked the BIOS settings and all the Wake on Lan settings are Disabled. I've used the ethtool command and the wake on lan is set to "d" which I've read been off. Can anyone suggest anything?

  • How to get started in the development industry? [closed]

    - by Peter Fren
    My life is coding. I was born in 1982 and my first computer was an amiga. I started learning Amiga BASIC. To cut a long story short, I know many things about several programming languages. Being unemployed(I achieved the german abitur, should be similar to a high school degree and I studied a few semesters of mechanical engineering in 2002(I learned JAVA back then)) I have no idea how to use this ability. I have never done commissional work, every task I solved was based on my own wishes and desires. I do not know how to write a FSD or PRD or put it into code. So the question is, why should anyone hire me? I specialized in kinect development but all jobs I applied for on odesk and similar were awarded to others without me knowing why. I don't know what I should do with my skills professionally. What do you suggest? As this board has weird rules, tell me where to find answers if this is the wrong place.

  • How to minimize the usage of static variables and objects

    - by Peter Penzov
    I'm trying to implement this JavaFX code where I want to call remote Java class and pass boolean flag: final CheckMenuItem toolbarSubMenuNavigation = new CheckMenuItem("Navigation"); toolbarSubMenuNavigation.setOnAction(new EventHandler<ActionEvent>() { @Override public void handle(ActionEvent e) { //DataTabs.renderTab = toolbarSubMenuNavigation.isSelected(); DataTabs.setRenderTab(toolbarSubMenuNavigation.isSelected()); // call here the getter setter and send boolean flag System.out.println("subsystem1 #1 Enabled!"); } }); Java class which I want to call: public class DataTabs { private static boolean renderTab; // make members *private* private static TabPane tabPane; public static boolean isRenderTab() { return DataTabs.renderTab; } public static void setRenderTab(boolean renderTab) { DataTabs.renderTab = renderTab; tabPane.setVisible(renderTab); } // somewhere below // set visible the tab pane TabPane tabPane = DataTabs.tabPane = new TabPane(); tabPane.setVisible(renderTab); } This implementation works but I want to optimize it to use less static variables and objects. Can you tell me which sections of the code how can be optimized?

  • New to iPhone Development - iOS5 Storyboard

    - by Peter
    I'm new here and pretty new to iOS development. My question is basically, should I learn the old school development methods or just learn how to do things using the latest tools (i.e. Storyboard)? I've had a go with the Storyboard feature of XCode 4.2 and it's very powerful. My only concern is that it requires iOS 5. I don't mind learning the old way of doing things but I've been having trouble finding tutorials/examples for XCode 4.2 that don't use the storyboard. An example would be the with my trouble finding a good tutorial on how to embed a Navigation Controller into a TabBarController. A lot of the material out there seems to be for older version of XCode. Using the storyboard I'm able to set this up with seconds but still haven't managed to get it working without it. So in short :) would you guys suggest I continue my project using the Storyboard or make the extra effort to do things a little more manually?

  • Trying to install Proprietory Nvidia Graphics Drivers

    - by Peter Snow
    After reading and trying many different suggestions for some hours, I returned to this how-to: https://help.ubuntu.com/community/BinaryDriverHowto/Nvidia The first problem I encounter is how to identify which of the listed drivers support my Nvidia GEForce 630M graphics card. Following the links doesn't really help, since it is not stated there either (except where support for a new driver was added later which is explicitly stated, but the original devices covered are not). However, even if I knew, if it doesn't appear in the 'Additional Drivers' dialogue (see below), how will I install it? Second Issue: The article goes on to say that available drivers for my hardware are usually listed in 'Additional Drivers'. In my case, they aren't. Unfortunately, it doesn't tell me how to correct that or work around it? I've checked the bios and there is no way offered there to disable the integrated graphics, only the Nvidia graphics. I've also tried each available option in this: $ sudo update-alternatives --config i386-linux-gnu_gl_conf My system is an Acer Aspire 4752G bought May 2012. I'm running Ubuntu 12.04LTS. uname -a : 3.2.0-38-generic-pae #61-Ubuntu SMP Tue Feb 19 12:39:51 UTC 2013 i686 i686 i386 GNU/Linux It's 64bit hardware but I installed 32bit OS for greater software compatibility. Running $ sudo tail -fn 500 /var/log/Xorg.0.log | grep '(EE)' returns" (WW) warning, (EE) error, (NI) not implemented, (??) unknown. [ 28.886] (EE) Failed to initialize GLX extension (Compatible NVIDIA X driver not found) The reason for wanting the proprietor y drivers is because my laptop comes with 3D accelerated graphics adaptor and so rather than confining myself to struggling with the on-board graphics, I would rather use it. I also want to experiment with using it for bitmining (which uses the GPU's for computing power).

  • Le parti pirate vogue vers les législatives, et propose une campagne "libre et open-source", voterez-vous pour le parti en juin ?

    Le parti pirate vogue vers les législatives À un moment où tout le monde à les yeux rivés vers les élections présidentielles, les pirates regardent déjà plus loin vers l'horizon et scrutent les élections législatives de juin prochain. Leur objectif ? Obtenir leur premier siège à l'Assemblée nationale. Mais en premier lieu, le but du parti est de faire connaître leurs idées et d'amener des débats souvent ignorés par les autres partis. Siéger à l'Assemblée nationale serait l'idéal pour se faire entendre de la sphère politique. Mais, et c'est tout aussi important, les idées doivent aussi être entendues par les citoyens.

  • From Co-op to fulltime help with salary negotation [closed]

    - by Peter
    Hey I'm a coop student that worked at a particular medium size printing company for 8 months. I had a good time it was lax, sometimes insufficiently challenging but none the less I learned a whole lot. I stuck with them for another 5 months (including this month) at the same rate I was paid then, doing testing work, tool development, taking care of emergencies when the lead developers were away, and other smaller projects and now bigger projects and problem handling (bad printer output etc.). I know their website inside out (ecommerce), and I know their printing software inside out and have made many changes to them both without a hitch. I have also done a lot of refactoring of the existing code base which as far as Im concerned, I believe am the only one to do those sorts of restructuring even though there is constant talk about it. I guess the unit testing paid off and lets me see the value in modularity if even a tad more. Never the less I have faith in my skill and the restructuring I did turned out better than I had imagined . Now the problem is that I finish school next month and so I asked for a full time spot the month after. They have been expanding and have hired a new guy a few months after my coop spot, and just now they hired a new guy to deal with the CRM application. The lead developer who wrote all of the software had left 5 months ago so it was up to all of us to learn what he had done over 4 years (including db, networking). So now I'm afraid that if I assert myself for a salary similar to the other guys, which I believe I am certainly on par with, that I would be seen as ingrateful. It's hard to flip a switch and say, hey double my pay, although when I'm working with their bread and butter (printers) and writing new features, refactoring the whole application for extensibility. I love it regardless of pay. I also feel maybe I'm replaceeble, although nobody knows the website better than myself and the lead web dev (not by a long shot), and nobody knows the printer software/drivers better than myself. I just thought they would have brought up a raise earlier on, and now it feels like they don't value my work. I'm also tired of worrying about it. I think my question is, well what do I do next?

  • SQL vs. Oracle Live Debate (AKA Smackdown!)

    - by Peter W. DeBetta
    A few years ago I was speaking at a conference in Raleigh, NC where Ted Neward and I found a fun way to promote a Java vs. .NET debate that was planned one evening. We stood in the middle of a crowd during one of the breaks and starting “arguing” about Java vs. .NET with one another. Our voice levels quickly raised and we ended it by slapping each other across the face with a glove to request a challenge. It was a great way to segue to our announcing of the actual debate planned later that evening....(read more)

    Le HTML5, entre 6 et 10 fois moins rapide sur smartphones que sur bureau Le standard est-il vraiment adapté pour des jeux mobiles ? Le HTML5 sur mobile n'est pas encore tout à fait adapté pour les applications multi-plateformes complexes. C'est en résumé la conclusion d'une étude menée par la société spaceport.io qui souligne par exemple que le rendu des animations en HTML5 sur Smartphones et tablettes est très largement inférieur à celui sur PC de Bureau. Voilà qui a de quoi faire réfléchir sur la dimension "développer une fois, fonctionne partout" semblable à celle de Java et tant vantée pour la technologie Web comme alternative à des développements natifs.
