• Google devient une entreprise plus chère que Microsoft, changement d'époque ou sous-évaluation du premier éditeur mondial ?

  Google devient une entreprise plus chère que Microsoft Changement d'époque ou signe que les marchés sous-évaluent le premier éditeur mondial ? Le fait est simple. Google a aujourd'hui une capitalisation boursière supérieure à celle de Microsoft. Son interprétation, elle, est beaucoup plus complexe. Certains y verront un changement de paradigme (vers le 100% Web, l'abonnement, le contenu et le mobile). D'autres, le signe que les marchés sous-estiment l'assise de Microsoft dont le portefeuille produits et les clients sont beaucoup plus diversifiés. Le Wall Street Journal pour sa part remarque que l'action de Google était au plus bas depuis 4 ans au début de l'été. Les analyst...

• How Do Computers Work? [closed]

  - by Rob P.

  This is almost embarrassing ask...I have a degree in Computer Science (and a second one in progress). I've worked as a full-time .NET Developer for nearly five years. I generally seem competent at what I do. But I Don't Know How Computers Work! Please, bare with me for a second. A quick Google of 'How a Computer Works' will yield lots and lots of results, but I struggled to find one that really answered what I'm looking for. I realize this is a huge, huge question, so really, if you can just give me some keywords or some direction. I know there are components....the power supply, the motherboard, ram, CPU, etc...and I get the 'general idea' of what they do. But I really don't understand how you go from a line of code like Console.Readline() in .NET (or Java or C++) and have it actually do stuff. Sure, I'm vaguely aware of MSIL (in the case of .NET), and that some magic happens with the JIT compiler and it turns into native code (I think). I'm told Java is similar, and C++ cuts out the middle step. I've done some mainframe assembly, it was a few years back now. I remember there were some instructions and some CPU registers, and I wrote code....and then some magic happened....and my program would work (or crash). From what I understand, an 'Emulator' would simulate what happens when you call an instruction and it would update the CPU registers; but what makes those instructions work the way they do? Does this turn into an Electronics question and not a 'Computer' question? I'm guessing there isn't any practical reason for me to understand this, but I feel like I should be able to. (Yes, this is what happens when you spend a day with a small child. It takes them about 10 minutes and five iterations of asking 'Why?' for you to realize how much you don't know)

• Google lance Tag Manager, un outil gratuit qui facilite la gestion du suivi et des balises de marketing des sites Web

  Google lance Tag Manager un outil gratuit qui facilite la gestion du suivi et des balises de marketing des sites Web Google vient d'annoncer le lancement de Google Tag Manager, son nouvel outil pour la gestion des différentes balises dans un site Web. Pour mieux monétiser leur site Web et contrôler la manière dont le contenu est utilisé, les gestionnaires de sites ont recours à des outils de suivi de statistiques comme Google Analytics. Pour chaque service, un morceau de code doit être intégré dans chaque page du site. Bien que d'une utilisation relativement simple, la multiplication de ces bouts de code sur une page peut rendre leur gestion fastidieuse. De plus, les requêtes entr...

• Accidentally deleted my windows 7 while installing ubuntu, trying to reinstall it

  - by user286874

  I had Windows 7 Ultimate on my desktop and I believe have downloaded the correct ISO file. I've been trying to use GParted and UNetbootin to create a bootable usb by formatting to FAT32, flagging the boot box, and writing to the flash drive with UNetbootin, but there have been problems. When I select my flash drive in the BIOS, it just reflashes the BIOS stock MSI picture 4 times then boots to Ubuntu anyway. Details: it's a new computer, self-built, hasn't shown any problems in the past, got Windows 7 through r/softwareswap so it's a MSDN file, the flash drive is a Sandisk U3 Cruzer, I uninstalled the bloatware when Iwas using Windows 7, but in the BIOS it still comes up as "Sandisk U3 Cruzer" I don't have a cCD/DVD drive. I dont care if I have to completely delete ubuntu in the process, I just need Windows 7 back by monday. I think the problem is because of the cruzer and am going to pick up a different flash drive today.

• What's the best way to handle numerous recurring log entries in game loop?

  - by Kaa

  I have a custom logging system, use of which is scattered all over the engine and game. The system is linked to a "LogStore" that has an std::vector<string> logs[NUM_LOG_TYPES] - each vector corresponds with it's log type (info, error, debug, etc.). There's one extra std::vector that has "coordinates" to all log entries in the order they were received. Now, all the logging output is also displayed inside my development console in the game. The game console is handled by HTML-type GUI and therefore requires a new <p> element being added for each log output. My problem is that the log entries that are generated in the main loop each frame freeze the engine, because they continue to add elements to the in-game console, and if the console or guy generates a warning - that creates an infinite logging loop. I want to solve it by handling the recurring log entries in an elegant way that lets you know that something is critically wrong, but won't freeze the engine - like displaying the count of errors in the last 60 frames instead of displaying errors themselves. But how do you guys handle this? Does anyone know any nifty tricks to do this? I understand the question may sound vague, but if someone came across this type of issue I'm sure they would know exactly what's happening. Example problematic log entries: OpenGL warnings (I actually do check for errors every frame in many places) Really any prints anywhere in the main loop (may be debugging, may be warnings)

• Premier jour de Qt chez Digia, après son rachat de Nokia : le framework restera disponible sous GPL et LGPL

  Il y a une quinzaine de mois, Nokia « refilait » le support commercial de Qt à Digia ; certaines rumeurs parlaient déjà d'une revente complète de tout ce qui concerne le framework, il ne s'agissait que du support commercial ? à l'époque. Ces rumeurs se révèlent maintenant confirmées : Digia s'apprête à acquérir tout ce qui concerne Qt de Nokia (toutes les activités Qt, dont le développement du produit, les licences open source et commerciales, tout le service commercial). Ceci intervient dans une période relativement sombre pour Nokia (« Nokia coule-t-il à pic ? »), avec parfois des décisions douloureuses et, selon certains, injustifiables (pour se relan...

  - by user205996

  I really searched for information to this problem but none of the guides or threads on forums have helped, either i cant search or this havent come up. No nomodeset, forcevesa, turning brightness up or anything have worked.... I bought the laptop with ubuntu 13.04 preinstalled, bumblebeedrivers were on it but primusrun broke on the ubuntu 13.10 update. Decided to reinstall ubuntu and install windows at the same time, so now I got windows up and running from uefi and have installed ubuntu 13.10, grub works for windows and everything seems like normal. But when I try to boot ubuntu i cant manage to boot into anything else than failsafe rootterminal. Screen just go black or i have a blank terminal flashing i upper left corner.... Dont know anything about X configuration or what to do. If anyone has an idea please let me know. Laptop: Clevo w230st intel i7 haswell intel hd4000 (?) nvidia gtx765m

• Is it a good practice to create a list of definitions for all symbols and words in a programming language?

  - by MrDaniel

  After arriving at this point in Learning Python The Hard Way I am wondering if this is a good practice to create a list of symbols and define what they do as noted in bold below, for every programming language. This seems reasonable, and might be very useful to have when jumping between programming languages? Is this something that programmers do or is it just a waste of effort? Exercise 22: What Do You Know So Far? There won't be any code in this exercise or the next one, so there's no WYSS or Extra Credit either. In fact, this exercise is like one giant Extra Credit. I'm going to have you do a form of review what you have learned so far. First, go back through every exercise you have done so far and write down every word and symbol (another name for 'character') that you have used. Make sure your list of symbols is complete. Next to each word or symbol, write its name and what it does. If you can't find a name for a symbol in this book, then look for it online. If you do not know what a word or symbol does, then go read about it again and try using it in some code. You may run into a few things you just can't find out or know, so just keep those on the list and be ready to look them up when you find them. Once you have your list, spend a few days rewriting the list and double checking that it's correct. This may get boring but push through and really nail it down. Once you have memorized the list and what they do, then you should step it up by writing out tables of symbols, their names, and what they do from memory. When you hit some you can't recall from memory, go back and memorize them again.

• what to learn & practice to be a programmer (not for Job) [closed]

  - by Hanan N.

  I want to be able to write programs (tools) for my own needs, and I want to tell the computer what to do, not to be strict to what other's told it to do. I have a good knowledge of Linux & Windows, I am also have a bit of Python in my head, but I think that I need some guidance on what languages or practices to invest my time into in order to be able to tell the computer what to do. I know there is a lot of posts similar to what I am asking here, but there is a big difference and so I have opened this thread. My goal isn't to work at a company, so I don't need to learn how to work as a team, I don't need to learn as much how to maintain my code nor how to write it nice for others to understand (I know it is important but not for me). I don't want to learn it as a profession, but as a serious hobby (you can call it hacking as long as you know what cracking means), my end goal is to be able to understand other's people code, and to write my own code with a lot of deep knowledge of the ins and outs of the computer system in order to gain from it as much as I can. So in essence my questions are: How can I understand, in depth, computers, in order to exploit them as much as I can? What should I learn? Are there any books that I should read? Is it possible to do this, or do I have to learn every aspect of programming?

• Has the Appindicator or GtkMenu API changed in Saucy?

  - by marxjohnson

  I've written a custom application indicator, which isn't working properly on saucy. The menu is initialised with a few items, then updates regularly, adding or removing menu items. This worked fine <13.10, but on 13.10, the line that adds the menu to the indicator produces the following warning: Warning: /build/buildd/glib2.0-2.38.0/./gobject/gsignal.c:2475: signal 'child-added' is invalid for instance '0x24390e0' of type 'GtkMenu' self.ind.set_menu(self.menu) And the items added to the menu subsequently dont appear. A bug has been filed against several indicators for the same problem, but it's not clear to me whether this is a problem with the indicators as a result of an API change, or a bug in the GTK or Appindicator libraries. Does anyone know?

• Microsoft va aider les développeurs en sortant un SDK pour Kinect, afin de favoriser les avancées technologiques

  Microsoft va aider les développeurs en sortant un SDK pour Kinect, afin de favoriser les avancées technologiques Depuis sa sortie, le Kinect a été détourné des centaines de fois, dans des projets toujours plus audacieux. Des initiatives pas toujours appréciées par Microsoft. Cependant, la firme s'apprête à faire un grand virage en faveur des bidouilleurs informatiques. En effet, elle va sortir un logiciel leur ouvrant la porte aux entrailles de la bête. D'ici quelques semaines, un SDK (réservé au utilisations personnelles, mais une version commerciale devrait suivre) sera publié, à destination des développeurs, dont Microsoft espère qu'ils emmèneront sa technologie au niveau supérieur en offrant "de nouvelles p...

• Placeholders in strings

  - by dotancohen

  I find that I sometimes use placeholders in strings, like this: $ cat example-apache <VirtualHost *:80> ServerName ##DOMAIN_NAME## ServerAlias www.##DOMAIN_NAME## DocumentRoot /var/www/##DOMAIN_NAME##/public_html </VirtualHost> Now I am sure that it is a minor issue if the placeholder is ##DOMAIN_NAME##, !!DOMAIN_NAME!!, {{DOMAIN_NAME}}, or some other variant. However, I now need to standardize with other developers on a project, and we all have a vested interest in having our own placeholder format made standard in the organization. Are there any good reasons for choosing any of these, or others? I am trying to quantify these considerations: Aesthetics and usability. For example, __dict__ may be hard to read as we don't know how many underscores are in there. Compatibility. Will some language try to do something funny with {} syntax in a string (such as PHP does with "Welcome to {$siteName} today!")? Actually, I know that PHP and Python won't, but others? Will a C++ preprocessor choke on ## format? If I need to store the value in some SQL engine, will it not consider something a comment? Any other pitfalls to be wary of? Maintainability. Will the new guy mistake ##SOME_PLACEHOLDER## as a language construct? The unknown. Surely the wise folk here will think of other aspects of this decision that I have not thought of. I might be bikeshedding this, but if there are real issues that might be lurking then I would certainly like to know about them before mandating that our developers adhere to a potentially-problematic convention.

• What Languages are mostly understood "intuitively" and could benefit from a more formal learning approach?

  - by keppla

  In a presentation, i stumbled upon the Statement "JavaScript is a Language everybody uses, yet nearly noone seems to find it neccessary to learn how it works". And indeed, not many of the programmers i know could explain javascript's prototype concept, or why functions need to be 'bound' to this. CSS seems to be another example of this behaviour: everyone knows how to put a 'class' to an element, and to write a style .myclass { ... }, but only a few even know of margin-collapse. My question is: are there more of those languages, technologies, concepts, that are so prevalent that we dont even notice them as something worth learning while we use them?

• Looking for job advice [closed]

  - by EntryLevelJavaDeveloper

  I am a software developer for a government agency in DC, and I have recently completed one year of employment. I am generally dissatisfied with my experiences here. I do not want to gripe too much, but I do not spend a lot of time doing actual development on projects. I am asked to do everything under the sun: write requirements, review specs, test, attend random meetings, but actual coding makes up a small fraction of my time. The coding itself is fairly straightforward and simple so it feels like I am not growing from my experiences. I am not tasked with more challenging work, and I find the experiences are not rewarding. If I had a stronger resume/more work experience, I'd leave the position immediately but combined with the present economy, I am hesitant to leave. I have several questions: Does anybody have experiences like this? How did you make the most of it? I am currently doing some side projects, making simple webpages for people, but aside from that, and open source projects, what other things are out there? What are general benchmarks for a developer after one year of professional experience? What should I be expected to know/do? I am outsider (coming from a math/science background) so I do not know what exactly I should know/do. Is it possible to obtain a mentorship with a mid/senior developer to learn? If so, how can I go about making contacts in the DC area?

• Can I make a business in teaching home users Ubuntu [on hold]

  - by Dorgaldir

  I was thinking about a way to bring Ubuntu to the bigger public, since it has great advantages for people in the lower income class that only use a PC for basic usage. They pay for a windows licence without actually needing windows because 95% of what they do is in a browser and the other 5% is typing a word document or making a simpel Excel sheet. So for these people something like Ubuntu is ideal, they can prolong the life of their old PC or laptop with Ubuntu and thus saving extra money. And as we all know, saving money is not only interesting for the lowest of income but for most of us. But when I talk to people they don't want to use Ubuntu because they know Windows and they don't know this, they'll complain about having to adapt to windows 8 but adapting to Ubuntu seems a bridge too far. But what if someone in the neighborhood gave simple Ubuntu courses. Teaching people about Ubuntu, stuff like: What is an OS What is Ubuntu How do I obtain Ubuntu How do I install Ubuntu How do I set up my email in Ubuntu How do I make a text document in Ubuntu How do I update my facebook wall in Ubuntu ... Simple basic PC usage, but within Ubuntu. But as much as I would like to work for free all day, I can't do this for free for people outside of my social circle. So I was wondering if it is possible to make a business and make money with giving Ubuntu courses, or are their steps to be taken before this is possible. However... Do I need an Ubuntu or Canonical license? Do I need to get a certificate? Do I have to make some kind of deal or contract with Canonical? Just to be clear this is all just an idea in my head at this point, I'm just gathering information. I'm not a teacher at a school, just a programmer that is thinking about options in life. Thanks in advance!

• How do i allow non-root access to /ttyUSB0 on 12.04?

  - by yurividal

  Since i updated from 10.04 to 12.04, i am unable to acces the device connected in /ttyUSB0 if i dont have root access. To be more specific, i use a usb-to-serial com port converter to acces and configure Cisco equipment with a software called Putty. It happens that, since i upgraded to 12.04, Putty only sees the connected device when i run it as "gksudo putty". If not, it says "unable to connect to port /ttyUSB0". I have managed to change the permissions via chmod 666, and it works, but if i disconnect the usb and reconnect, it goes back to root only. How do i permanently allow non-root access? I have a clue it might be via udev rules, but i have NO IDEIA how to do it. obs. Manufacturer and drivers "PROLIFIC"

• Vista missing from grub bootlist after installing ubuntu

  I installed Ubuntu on a logical partition a while ago. When I get to the grub bootlist, Vista is not there. What i get is this: Ubuntu, with linux 2.6.32-26 Ubuntu, with linux 2.6.32-26 (Recovery mode) Ubuntu, with linux 2.6.32-25 Ubuntu, with linux 2.6.32-26 (Recovery mode) Ubuntu, with linux 2.6.32-24 Ubuntu, with linux 2.6.32-26 (Recovery mode) Memory test (memtest86+) Windows vista (loader) (on/dev/sda1) windows recovery environment (loader) (on/dev/sda2) "Windows vista (loader)" is an acer erecovery manager Im guessing that grub installed on my primary partition so it overwrite the vista MBR and i dont have the option to boot vista. Is there some way i can just edit the MBR and add vista to it or how will i have to repair this? here is my boot script http://pastebin.com/7HZFjBT7

• PHP I am pulling my hair out trying to find the best! [closed]

  - by darga33

  PULLING MY HAIR OUT I have heard of Martin Fowler's book PoEAA and the other book Head First OOA OOD but those are not in PHP. I DESPERATELY WANT TO READ THEM, but ONLY in PHP utilizing SOLID principles! Does anyone know of the absolute best, most recent PHP book that utilizes the SOLID principles and GRASP, and all the other best practices? I want to learn from the best possible source! Not beginner books! I already understand OOP. This seems like an almost impossible question to find the answer to and so I thought, hey, might as well post on stackexchange!! Surely someone out there must know!!!!!!!!!! Or if noone knows Maybe they know of an open source application that utilizes these principles that is relatively small that is not a framework. Something that I can go through every single class, and spend time understanding the insides and outs of how the program was developed. Thanks so much in advance! I really really really really appreciate it!
