  • How to Recover that Photo, Picture or File You Deleted Accidentally

    - by The Geek
    Have you ever accidentally deleted a photo on your camera, computer, USB drive, or anywhere else? What you might not know is that you can usually restore those pictures—even from your camera’s memory stick. Windows tries to prevent you from making a big mistake by providing the Recycle Bin, where deleted files hang around for a while—but unfortunately it doesn’t work for external USB drives, USB flash drives, memory sticks, or mapped drives. Luckily there’s another way to recover deleted files. Note: we originally wrote this article a year ago, but we’ve received this question so many times from readers, friends, and families that we’ve polished it up and are republishing it for everybody. So far, everybody has reported success!

  • Sega lance des jeux vidéos dirigés par les jets d'urine, dont les consoles sont installées dans les urinoirs

    Sega lance des jeux vidéos dirigés par des jets d'urine, dont les consoles sont installées dans les urinoirs Ras-le-bol des jeux vidéos conventionnels ?

  • Google accuse Bing de copier ses résultats de recherche, suite aux résultats de tests qu'il a effectué

    Google accuse Bing de copier ses résultats de recherche, suite aux résultats de tests qu'il a effectué Google vient de porter de graves accusations concernant son rival Bing. Mountain View a en effet effectué dans le plus grand secret divers tests. Ainsi, cent termes qui ne génèrent habituellement aucune réponse sur le web ont été "truqués" par Google, qui a crée de faux résultats à leur sujet, qui n'auraient donc logiquement jamais du apparaître. Puis, la firme a attendu... Et, au bout de seulement quinze jours, ils sont apparus sur Bing. Ce qui a conduit Google a déclarer, furieux, que le moteur de recherche de Microsoft copie ses propres résultats, ajoutant même que "Microsoft ne le nie pas".

  • Google open-source sa plateforme de déploiement des logiciels Mac, Simian est désormais disponible sous licence Apache

    Google open-source sa plateforme de déploiement des logiciels Mac, Simian est désormais disponible sous licence Apache Simian est une plateforme développée par Google pour répondre aux besoins des développeurs et leur permettre de déployer des logiciels Mac OS X sur toutes les machines d'un parc informatique. La petite histoire voudrait que sa création aie été lancée suite aux attaques chinoises, qui auraient motivé la direction de Google pour migrer tous les employés de la firme sous des systèmes moins exploités par les pirates, comme Mac OS X et Linux. Ses possibilités sont nombreuses et devraient simplifier la vie des programmeurs adeptes de la Pomme : - déployer un logiciel ou une mise à jour sur u...

  • Les processeurs multi-cores pourraient gagner en performances, grâce à des communications internes six fois plus rapides

    Les processeurs multi-cores pourraient gagner en performances, grâce à des communications internes six fois plus rapides Des chercheurs américains, de l'Université de la Caroline du Nord, on fait une découverte qui pourrait améliorer les performances des puces multicores. En effet, la majorité des processeurs actuels de 4 ou 8 coeurs, connaissent des difficultés à voir leurs cores communiquer directement entre eux. Mais une alternative serait possible. Au lieu de devoir passer par la mémoire pour envoyer et récupérer des données, plusieurs coeurs travaillant sur la même tâche pourraient bénéficier d'une accélération matérielle. En effet, les ingénieurs développant le projet ont mis au point une HAQu (h...

  • Intel obligé de rappeler ses puces Sandy Bridge, à cause d'un problème de port SATA

    Intel obligé de rappeler ses puces Sandy Bridge à cause d'un problème de port SATA, il pourrait lui en coûter 1 milliard de dollars Mise à jour du 01.02.2011 par Katleen Parfois, une petite erreur peut chambouler de grandes choses. C'est ce qui est en train d'arriver à Intel, avec ces processeurs Sandy Bridge. La compagnie se voit en effet contrainte de les rappeler, ce qui risque de perturber le travail des constructeurs de PCs. En effet, les puces de la gamme Series 6 (qui sont incorporées dans tous les systèmes Sandy Bridge) ont un problème avec leur port SATA (Cougar Point) : il risque de "se dégrader avec le temps", ce qui pourrait avoir un impact sur les performances ou la fo...

  • Internship in License Contract Management

    - by cristian.condurache(at)oracle.com
    Hi Everyone, My name is Luca. I am an intern in the License Contract Management team in Italy. I have studied Economics and Business in Pescara and finished my Master’s Degree in July 2009. After a short work experience near my home town I decided to look for a job in an International Company. I got in touch with Oracle in January 2010. I had a telephone interview and then a face-to-face interview. On a cold and grey morning, I arrived in Milan....my first impression was fantastic....a big modern building with wide TVs everywhere. I was a little nervous but very excited. I understood this could be a great opportunity... The interview went well and I started to work in March. After a training period I was quickly involved in the closing of the last quarter of the fiscal year - of which May is the last month at Oracle. Working as a License Contract Manager is a real challenge for a fresh graduate. It involves thoroughly understanding the Oracle Policies and Practices with regards to License Contracts. In my experience, especially in May, I learnt to work under high pressure, within time constrains, and to keep up with constant changes. In this period I also had the opportunity to be involved in different negotiations, being directly in contact with the customers. This helped me to develop my relational skills during complex transactions. Looking back at the nine months at Oracle I can say I have a better understanding of the IT world. It is a complex environment that changes continously, offering new challenges to learn from everytime. If you have any questions related to this article feel free to contact [email protected]. You can find our job opportunities via http://campus.oracle.com. Technorati Tags: License Contract Management,oppotunity,Oracle Policies,internship

  • A bacon- (and module-) saving PowerShell incident

    - by AaronBertrand
    Earlier today I made a big goof. I opened a module in Notepad, intending to use it as the basis for a new module. I was in the process of using "File > Save As" when my phone rang just at the precise instant that, for some reason, made me click on "File > Save" by mistake. After hitting Ctrl+Z 30 times to try to get the old version of the module back, I remembered that Notepad has never had more than one level of Undo. Back when I was coding ASP by hand, I was very well aware of this, but I...(read more)

  • Windows Azure Emulators On Your Desktop

    - by BuckWoody
    Many people feel they have to set up a full Azure subscription online to try out and develop on Windows Azure. But you don’t have to do that right away. In fact, you can download the Windows Azure Compute Emulator – a “cloud development environment” – right on your desktop. No, it’s not for production use, and no, you won’t have other people using your system as a cloud provider, and yes, there are some differences with Production Windows Azure, but you’ll be able code, run, test, diagnose, watch, change and configure code without having any connection to the Internet at all. The best thing about this approach is that when you are ready to deploy the code you’ve been testing, a few clicks deploys it to your subscription when you make one.   So what deep-magic does it take to run such a thing right on your laptop or even a Virtual PC? Well, it’s actually not all that difficult. You simply download and install the Windows Azure SDK (you can even get a free version of Visual Studio for it to run on – you’re welcome) from here: http://msdn.microsoft.com/en-us/windowsazure/cc974146.aspx   This SDK will also install the Windows Azure Compute Emulator and the Windows Azure Storage Emulator – and then you’re all set. Right-click the icon for Visual Studio and select “Run as Administrator”:    Now open a new “Cloud” type of project:   Add your Web and Worker Roles that you want to code:   And when you’re done with your design, press F5 to start the desktop version of Azure:   Want to learn more about what’s happening underneath? Right-click the tray icon with the Azure logo, and select the two emulators to see what they are doing:          In the configuration files, you’ll see a “Use Development Storage” setting. You can call the BLOB, Table or Queue storage and it will all run on your desktop. When you’re ready to deploy everything to Windows Azure, you simply change the configuration settings and add the storage keys and so on that you need.   Want to learn more about all this?   Overview of the Windows Azure Compute Emulator: http://msdn.microsoft.com/en-us/library/gg432968.aspx Overview of the Windows Azure Storage Emulator: http://msdn.microsoft.com/en-us/library/gg432983.aspx January 2011 Training Kit: http://www.microsoft.com/downloads/en/details.aspx?FamilyID=413E88F8-5966-4A83-B309-53B7B77EDF78&displaylang=en

  • Ruby or Python?

    - by Bobby Tables
    Hi all, This question is extremely subjective and open-ended. It might even sound like something I should just research for myself and make my own decision. But I'd like to put it out there and get some thoughts from others. Long story short - I burned out with the rat race and am on a self-funded sabbatical this year. Much of it is to take a break from the corporate grind and travel around, but I also want to play around with new technologies and do some self-learning projects, to stay up to speed on programming, and well - I just love tinkering with programming, when there's no pressure! Here's the thing: I am a lifetime C/C++/Java programmer. I'm a bit of a squiggly bracket snob since I've been working with this family of languages for my entire programming career. So I'd like to learn a language which isn't so closely syntactically related to this group. What I'm basically looking for is a language which is relatively general purpose, fun to learn, has some new concepts that are different from C++/Java, and has a good community. A secondary consideration is that it has good web development frameworks. A tertiary consideration is that it's not totally academic (read: there are real world jobs out there using it). I've narrowed it down to Ruby or Python. My impression of Ruby is that it is extremely web oriented - that the only real application of it is as a server side scripting language for doing web stuff (mainly Ruby on Rails). For Python I'm not so sure. TL;DR and to put it as succinctly as possible: which of these would be better for a C++/Java guy to learn to get some new perspectives on programming? And which is more open and general purpose and applicable to a wider set of applications? I'm leaning towards Ruby at the moment, but I worry to an extent that it looks like it's used as nothing but a server side web language.

  • What are safe keys to remap in vim?

    - by Weeble
    So far I've been trying to use Vim in as vanilla a configuration as possible, so as to save myself hassle when moving between machines. However, there are a few things I'd really like to bind keys, such as to shorten "_diwP which I use often to delete the word under the cursor and replace it with one from the clipboard. Are there any particular keys that are conventionally reserved for user-defined mappings? The point of this question is mostly that I would like to avoid hassle later on when I decide to install some plugin or take my configuration files to vim on another OS and find that my key mappings clash with something else.

  • Studies on code documentation productivity gains/losses

    - by J T
    Hi everyone, After much searching, I have failed to answer a basic question pertaining to an assumed known in the software development world: WHAT IS KNOWN: Enforcing a strict policy on adequate code documentation (be it Doxygen tags, Javadoc, or simply an abundance of comments) adds over-head to the time required to develop code. BUT: Having thorough documentation (or even an API) brings with it productivity gains (one assumes) in new and seasoned developers when they are adding features, or fixing bugs down the road. THE QUESTION: Is the added development time required to guarantee such documentation offset by the gains in productivity down-the-road (in a strictly economical sense)? I am looking for case studies, or answers that can bring with them objective evidence supporting the conclusions that are drawn. Thanks in advance!

  • controlling an object through another object ?

    - by Stefano Borini
    Today I've seen the following pattern: you have an object A and an object B. Object B accepts a pointer to A at its constructor. Once B is created, there's a method B.doCalc() that performs a calculation (internally using A's information). The result is obtained with method B.getResult(). In order to perform another calculation, A is modified, and B.doCalc() is called again. What is your opinion on this choice ? I would have designed it differently, but I want to hear your voice. Edit : note that my main objection is to modify A to have a different result from B, without touching B. Although similar, I think that just this discipline expresses a much better feeling of what's going on. Instead of a = new A a.whatever = 5 b = new B(a) b.doCalc() res = b.getResult() a.whatever = 6 b.doCalc() res = b.getResult() You get the a pointer object from b itself. a = new A a.whatever = 5 b = new B(a) b.doCalc() res = b.getResult() a = b.getAPointer() a.whatever = 6 b.doCalc() res = b.getResult() because it makes more explicit the fact that a is taken from b and then modified. I still don't like it, though...

  • Learning to be a good developer: what parts can you skip over?

    - by Andrew M
    I have set myself the goal of becoming a decent developer by this time next year. By this I mean full experience of the development 'lifecycle,' a few good apps/sites/webapps under my belt, and most importantly being able to work at a steady pace without getting sidelined for hours by some should-know-this-already technique. I'm not starting from scratch. I've written a lot of html/css, SQL, javascript, python and VB.net, and studied other languages like C and Java. I know about things like OOP, design patterns, TDD, complexity, computational linguistics, pointers/references, functional programming, and other academic/theoretical matters. It's just I can't say I've really done these things yet. So I want to get up to speed, and I want to know what things I can leave till a later date. For instance, studying algorithms and the maths behind them is interesting and all, but so far I've hardly needed to write anything but the most basic nested loops. Investigating Assembly to have a clearer picture of low-level operations would be cool... but I imagine rarely infringes on daily work. On the other hand, looking at a functional programming language might help me write programs that are more comprehensible and less prone to hidden failures (at the moment I'm finding the biggest difficulty is when the complexity of the app exceeds my capacity to understand it - for instance passing data around was fine... until I had to start doing it with AJAX, which was a painful step up). I could spend time working through case studies of design patterns, but I'm not sure how many of them get used in 'real life.' I'm a programmer with basic abilities - what skills should I focus on developing? (also my Unix skills are very weak, and also knowledge of Windows configuration... not sure how much time I should spend on that)

  • Dependent on CVS tagging for automated builds

    - by OMG Ponies
    My current work relies on using tags in CVS for an automated build process (ANT currently) to build for respective environments (development, QA, production). From our research, neither Git or Subversion support tagging in the same manner. If we use Subversion or Git, they don't support tags (in the same manner - please correct me?). So how would ANT or Maven know what to pick up for the respective build? Example: For a webapp, when viewing our repository say for the web.xml file -- the history would look like: web.xml v1 ... web.xml v1.2.3 Tag: Prod web.xml v1.2.4 web.xml v1.2.5 Tag: QA web.xml v1.2.6 web.xml v1.2.7 Head The ANT build scripts are run as CRON jobs, at different times & intervals for different environments. The environment build is based on the repository checkout, based on the tag. Development continues, and eventually the respective tags are moved: web.xml v1 ... web.xml v1.2.3 web.xml v1.2.4 web.xml v1.2.5 web.xml v1.2.6 Tag: Prod web.xml v1.2.7 Tag: QA web.xml v1.2.8 Head

  • Best practise for Progress Bar in Python's PyGTK

    - by Matthew Walker
    I would like to get feedback on others' opinions of best practice for how to implement a progress bar in Python's PyGTK. The work that the progress bar was to represent was very significant computationally. Therefore, I wanted the work to be done in a separate process (thus giving the operating system the possibility to run it on a different core). I wanted to be able to start the work, and then continue to use the GUI for other tasks while waiting for the results. I have seen many people asking this question indirectly, but I have not seen any concrete expert advice. I hope that by asking this question we will see a community's combined expertise. I have read the FAQ and I hope that "Programmers" is the right place to ask.

  • Why is 2^16 a "special" number?

    - by javamonkey79
    OK, I feel stupid asking this - but in Jeff's article: Getting the Interview Phone Screen Right and originally stated in the 5 essential phone screen questions: They shouldn't stare blankly at you when you ask with 2^16 is. It's a special number. They should know it. I've been a developer\software engineer\code monkey\whatever for a little while now, and I don't think I've ever come across this. I mean, I can certainly count binary values do basic operations on them, etc, etc. But I don't see what is "special" about this value.

  • How should I pronounce the :: and -> in PHP?

    - by Renesis
    When I read these lines aloud to someone: $controller->process(); UserManager::getInstance(); How should the -> and :: be pronounced? Reading the characters themselves in cumbersome and I don't know of any nicknames for them. Being a developer who is used to C-style syntax, I'd like to say "dot", but I'd like something that is easy to say and people can easily understand. It would also be good to know if there are any pronunciations that have become de-facto standards among teams of developers.

  • How do I account for changed or forgotten tasks in an estimate?

    - by Andrew
    To handle task-level estimates and time reporting, I have been using (roughly) the technique that Steve McConnell describes in Chapter 10 of Software Estimation. Specifically, when the time comes for me to create task-level estimates (right before coding begins on a project), I determine the tasks at a fairly granular level so that, whenever possible, I have no tasks with a single-point, 50%-confidence estimate greater than four hours. That way, the task estimation process helps with constructing the software while helping me not to forget tasks during estimation. I come up with a range of hours possible for each task also, and using the statistical calculations that McConnell describes along with my historical accuracy data, I can generate estimates at other confidence levels when desired. I feel like this method has been working fairly well for me. We are required to put tasks and their estimates into TFS for tracking, so I use the estimates at the percentage of confidence I am told to use. I am unsure, however, what to do when I do forget a task, or I end up needing to do work that does not neatly fall within one of the tasks I estimated. Of course, trying to avoid this situation is best, but how do I account for forgotten/changed tasks? I want to have the best historical data I can to help me with future estimates, but right now, I basically am just calculating whether I made the 50%-confidence estimate and whether I made it inside the ranged estimate. I'll be happy to clarify what I'm asking if needed -- let me know what is unclear.

  • Online training modules / programs for best software engineering practices?

    - by Steve
    We're taking over a team in a foreign country and the programming standards there aren't up to par with US standards. Folks there lack the formal training and basic understanding of computing concepts of databases, how computers work, what good software engineering practices are. Short of sending these ppl to college again, are there good online courses available that we can enroll them into so that they can upgrade their skills? I am specifically looking for online training courses, but recommendations for books are also welcome. This is language-agnostic.

  • How do I mount Samba share as non-root user

    - by Android Eve
    Is there a step-by-step tutorial that instructs in detailed step-by-step how to smbmount a Samba share to be used by a non-root user on a Ubuntu 10.04 desktop? Note: there are numerous threads on Google search dealing with this seemingly new problem. Instructions that used to work on Ubuntu 8.04 (or an older version of smbfs) no longer work. I need something fresh, punctual and especially reproducible. Thanks.
