  • Do higher resolution laptop displays matter for programmers?

    - by Jason Baker
    I'm buying a new laptop that I'll be using mainly for programming. A couple of options that really intrigue me are the Asus Zenbook UX31A and the new Retina Macbook Pro. It's obvious that the high-resolution displays on these laptops is useful for entertainment, photo-editing, and other things. My question is this: Do these displays provide any benefit for programmers? Do these displays make code any easier to read? Are they any easier on the eyes after a whole day of staring at the screen?

  • Blank screen after installing nvidia restricted driver

    - by LaMinifalda
    I have a new machine with a MSI N560GTX Ti Twin Frozr II/OC graphic card and MSI PH67A-C43 (B3) main board. If i install the current nvidia restricted driver and reboot the machine on Natty (64-bit), then i only get a black screen after reboot and my system does not respond. I can´t see the login screen. On nvidia web page i saw that the current driver is 270.41.06. Is that driver used as current driver? Btw, i am an ubuntu/linux beginner and therefore not very familiar with ubuntu. What can i do to solve the black screen problem? EDIT: Setting the nomodeset parameter does not solve the problem. After ubuntu start, first i see the ubuntu logo, then strange pixels and at the end the black screen. HELP! EDIT2: Thank you, but setting the "video=vesa:off gfxpayload=text" parameters do no solve the problem too. Same result as in last edit. HELP. I would like to see Unity. This is my grub: GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="video=vesa:off gfxpayload=text nomodeset quiet splash" GRUB_CMDLINE_LINUX=" vga=794" EDIT3: I dont know if it is important. If this edit is unnecessary and helpless I will delete it. There are some log files (Xorg.0.log - Xorg.4.log). I dont know how these log files relate to each other. Please, check the errors listed below.

  • "Il faut repenser les OS pour les processeurs multi-coeurs", d'après Microsoft

    "Il faut repenser les OS pour les processeurs multi-coeurs", d'après Microsoft Dave Probert est expert du noyau chez Microsoft. Selon lui, l'approche actuelle du multi-coeur n'est pas encore à même d'en exploiter toute la puissance, et est trop "compliquée". Aussi, propose-t-il une autre organisation. Car, d'après lui, "la solution" ne se situerait pas dans l'amélioration de techniques "comme le parallel programming, mais plutôt dans le refonte des abstractions de base qui constituent le modèle du système d'exploitation". Il explique qu'on ne tire pas assez parti des performances offertes par les processeurs multicoeurs et qu'aujourd'hui, on ne devrait plus avoir à patienter de...

  • Why isn't Java more widely used for game development?

    - by Anto
    I'm not a game developer or anything, but I know that Java is not very widely used for game development. Java should be fast enough for most games, so where's the catch? I can think of some reasons: Lack of game developers with expertice in Java Lack of good game development frameworks Programmers don't want to accept Java as a games programming language. Most only accept C++ as that? No support for game consoles (though the PC market still exists) It could of course be something else. Could someone who knows the business better than me explain why Java isn't getting momentum when it comes to game development?

  • Ubuntu on Mac mini and refit

    - by Thomas
    I have successfully installed Ubuntu pangolin 64 bit on a mac mini 2011 5,3 ( server version ). I have used the Ubuntu iso which I then converted to .dmg and dd'ed into an usb stick. I didn't want to keep OS X installed so I deleted the current partition and reformatted the drive as ext4 for / + a small swap partition. Everything seems to work nicely, but I have now a question since I read lots of reviews/howto when you people installed rEfit on Mac OS X. Did you use rEfit to be able to have a dual boot or there are other advantages by doing that ( apart that you will be able to download updated firmware for your hardware in the future via Mac OS ) like BIOS emulation and the like ?

  • Algorithms and Programmer's day-to-day job

    - by Lior Kogan
    As of July 10, 2012, Stack Overflow contains 3,345,864 questions, out of which 20,840 questions are tagged as "Algorithm" - this is less than 0.6% ! I find it disturbing. Many programmers have several years of academic education in computer science / software engineering. Most of them are smart... When asked, most would say that they love algorithms. Computer programming is generally about solving problems using algorithms... Yet, only 1 of 160 questions is tagged as algorithm related. What does it say about our profession?

  • Should a senior developer refuse to take paper exams during an interview?

    - by ??? Shengyuan Lu
    I found that many senior developers refuse to do paper exams in interviews. They regard the exam as a kind of humiliation, because they think that "They don't trust my programming ability even if I have five years working experience... only junior staff need take a paper exam...". However, Joel insists: 11. Do new candidates write code during their interview? Would you hire a magician without asking them to show you some magic tricks? Of course not. Is it justifiable if a senior developer refuses to take a paper exam in an interview?

  • Good university for computer science with plans for game development

    - by DukeYore
    I am starting my computer science degree at a local community college in programming using C++. However, I will be transferring to a 4-year university. Does anyone have any insight on university programs? I know Cal State Fullerton has a degree with a minor in Game Development. however, is that as important as getting a degree from a really great school? If I could shoot for something like Cal Poly would that be better? Or even Stanford or SF State being so close to so many gaming companies up there in the Bay area? Thank you in advance for any guidance.

  • Will high reputation in Programmers help to get a good job?

    - by Lorenzo
    In reference to this question, do you think that having a high reputation on this site will help to get a good job? Aside silly and humorous questions, on Programmers we can see a lot of high quality theory questions. I think that, if Stack Overflow will eventually evolve in "strictly programming related" (which usually is "strictly coding related"), the questions on Programmers will be much more interesting and meaningful ("Stack Overflow" = "I have this specific coding/implementation issue"; "Programmers" = "Best practices, team shaping, paradigms, CS theory"). So could high reputation on this site help (or at least be a good reference)? And then, more o less than Stack Overflow?

  • Oracle Exalogic Elastic Cloud - Planned Webcasts

    - by chuck.speaks
    I’m putting together a collection of recorded webcasts around Oracle Exalogic Elastic Cloud (Exalogic).  The plan is to do a systems overview and then multiple deep dives into hardware and software components that make up the engineered system. Those of you that are members of our partner community (Oracle Partner Network), drop me a note if you are interested in a full blown in-class delivery via PTS resources.  There is no schedule for these workshops but if there is enough interest, I would venture to guess it would roll out soon. Those of you with applications certified on Oracle WebLogic server that would like to scale to Exalogic, see me or watch this space.   Chuck Speaks chuck <dot> speaks at oracle <dot> com

  • Server Side Developer Prerequisites

    - by Jking
    I am new to server side development and am currently learning node.js. What sort of networking information should I be familiar with to allow for a smooth learning curve with server side development. Could anyone provide resources pertaining to the information required to get into server programming? To give you a better idea of my standpoint: I do not know how a server interacts with a database [Q: How does a NoSQL database, or database in general, communicate with a server?] I am unsure of how a web stack works [Q: I have heard of LAMP but do not know how Apache, MySQL, and PHP interact. Hopefully this applies to other stacks as well. How do the components of a stack work together? Also, is a MEAN stack an alternative, or is it completely irrelevant to this] I have trivial knowledge of internet protocol [however extremely inefficient][Q: What resources are beneficial when learning about networking, and how much/what knowledge should I acquire to program on the server side] I am unsure of what I am unsure of concerning networking information necessary to start development Information on how the client-server model works would be greatly appreciated

  • Availability Best Practices on Oracle VM Server for SPARC

    - by jsavit
    This is the first of a series of blog posts on configuring Oracle VM Server for SPARC (also called Logical Domains) for availability. This series will show how to how to plan for availability, improve serviceability, avoid single points of failure, and provide resiliency against hardware and software failures. Availability is a broad topic that has filled entire books, so these posts will focus on aspects specifically related to Oracle VM Server for SPARC. The goal is to improve Reliability, Availability and Serviceability (RAS): An article defining RAS can be found here. Oracle VM Server for SPARC Principles for Availability Let's state some guiding principles for availability that apply to Oracle VM Server for SPARC: Avoid Single Points Of Failure (SPOFs). Systems should be configured so a component failure does not result in a loss of application service. The general method to avoid SPOFs is to provide redundancy so service can continue without interruption if a component fails. For a critical application there may be multiple levels of redundancy so multiple failures can be tolerated. Oracle VM Server for SPARC makes it possible to configure systems that avoid SPOFs. Configure for availability at a level of resource and effort consistent with business needs. Effort and resource should be consistent with business requirements. Production has different availability requirements than test/development, so it's worth expending resources to provide higher availability. Even within the category of production there may be different levels of criticality, outage tolerances, recovery and repair time requirements. Keep in mind that a simple design may be more understandable and effective than a complex design that attempts to "do everything". Design for availability at the appropriate tier or level of the platform stack. Availability can be provided in the application, in the database, or in the virtualization, hardware and network layers they depend on - or using a combination of all of them. It may not be necessary to engineer resilient virtualization for stateless web applications applications where availability is provided by a network load balancer, or for enterprise applications like Oracle Real Application Clusters (RAC) and WebLogic that provide their own resiliency. It's (often) the same architecture whether virtual or not: For example, providing resiliency against a lost device path or failing disk media is done for the same reasons and may use the same design whether in a domain or not. It's (often) the same technique whether using domains or not: Many configuration steps are the same. For example, configuring IPMP or creating a redundant ZFS pool is pretty much the same within the guest whether you're in a guest domain or not. There are configuration steps and choices for provisioning the guest with the virtual network and disk devices, which we will discuss. Sometimes it is different using domains: There are new resources to configure. Most notable is the use of alternate service domains, which provides resiliency in case of a domain failure, and also permits improved serviceability via "rolling upgrades". This is an important differentiator between Oracle VM Server for SPARC and traditional virtual machine environments where all virtual I/O is provided by a monolithic infrastructure that itself is a SPOF. Alternate service domains are widely used to provide resiliency in production logical domains environments. Some things are done via logical domains commands, and some are done in the guest: For example, with Oracle VM Server for SPARC we provide multiple network connections to the guest, and then configure network resiliency in the guest via IP Multi Pathing (IPMP) - essentially the same as for non-virtual systems. On the other hand, we configure virtual disk availability in the virtualization layer, and the guest sees an already-resilient disk without being aware of the details. These blogs will discuss configuration details like this. Live migration is not "high availability" in the sense of "continuous availability": If the server is down, then you don't live migrate from it! (A cluster or VM restart elsewhere would be used). However, live migration can be part of the RAS (Reliability, Availability, Serviceability) picture by improving Serviceability - you can move running domains off of a box before planned service or maintenance. The blog Best Practices - Live Migration on Oracle VM Server for SPARC discusses this. Topics Here are some of the topics that will be covered: Network availability using IP Multipathing and aggregates Disk path availability using virtual disks defined with multipath groups ("mpgroup") Disk media resiliency configuring for redundant disks that can tolerate media loss Multiple service domains - this is probably the most significant item and the one most specific to Oracle VM Server for SPARC. It is very widely deployed in production environments as the means to provide network and disk availability, but it can be confusing. Subsequent articles will describe why and how to configure multiple service domains. Note, for the sake of precision: an I/O domain is any domain that has a physical I/O resource (such as a PCIe bus root complex). A service domain is a domain providing virtual device services to other domains; it is almost always an I/O domain too (so it can have something to serve). Resources Here are some important links; we'll be drawing on their content in the next several articles: Oracle VM Server for SPARC Documentation Maximizing Application Reliability and Availability with SPARC T5 Servers whitepaper by Gary Combs Maximizing Application Reliability and Availability with the SPARC M5-32 Server whitepaper by Gary Combs Summary Oracle VM Server for SPARC offers features that can be used to provide highly-available environments. This and the following blog entries will describe how to plan and deploy them.

  • Reuseable Platform For Custom Board Game

    - by George Bailey
    Is there a generic platform to allow me to customize the rules to a board game. The board game uses a square grid, similar to Checkers or Chess. I was hoping to take some of the work out of creating this computer opponent, by reusing what is already written. I would think that there would be a pre-written routine for deciding which moves would lead to the best outcome, and all that I would need to program is the pieces, legal moves, what layout constitutes a win/lose or draw, and perhaps some kind of scoring for value of pieces. I have seen chess programs that appear to use a recursive routine, so they think anywhere from 2 to 20 moves ahead to create varying degrees of difficulty. I have noticed this on chess.com. The game I am programming will not be as complex. Is there a platform designed to be re-used for different grid/piece based games. JavaScript would be preferable, but Java or Perl would be acceptable.

  • Working as an entry .Net Developer in the USA [closed]

    - by Abdullah
    I just have a question about .net entry level jobs in VA. I am a master degree student in field of software engineering but I am graduated from department of physics. I decided to work on Java first, but I have changed my mind because I don't have any Java programming background except Java class in master degree so I decided to work on C# because it was easy to me to work with Visual Studio and it's fun to me to work with SQL database and HTML stuffs. And I am a member of a IT consultant company in Reston where I took course from there about .net and I created online recruitment system for their web site. Now I am applying for CPT (internship) but I didn't work in a company as a .net developer so I don't have experience. Here is my question. If I get CPT and find a job, what do software companies want from an entry level .net developer? and what do they ask as interview questions?

  • How to use Fixedsys in the Gnome Terminal, or wherever monospaced fonts are required

    - by Walter Tross
    I think that the Fixedsys font is one of the most readable monospaced fonts for programming. It has zero antialiasing, with vertical lines mostly 2 pixels wide. Close to ideal for current monitor dot pitches, in my eyes (literally). After years of Windows at home (for family reasons) and Linux servers at work accessed through Cygwin on Windows (for company policy reasons), with Fixedsys as the shell and IDE font, I have decided to switch to the Ubuntu desktop. Eclipse and gedit are no problem, they accept the Fixedsys Excelsior TTF font. But the Gnome Terminal only accepts monospaced fonts. Although Fixedsys Excelsior is essentially monospaced, it contains larger glyphs (mostly for eastern languages), and also some ligatures. Since apparently ALL characters must have the same width for a font to be recognized as monospaced, Fixedsys Excelsior cannot be selected in all those contexts where monospaced fonts are required, including gnome-terminal. So what is the easiest/cleanest way to use a Fixedsys clone font in contexts that only accept monospaced fonts?

  • Multiple Object Instantiation

    - by Ricky Baby
    I am trying to get my head around object oriented programming as it pertains to web development (more specifically PHP). I understand inheritance and abstraction etc, and know all the "buzz-words" like encapsulation and single purpose and why I should be doing all this. But my knowledge is falling short with actually creating objects that relate to the data I have in my database, creating a single object that a representative of a single entity makes sense, but what are the best practises when creating 100, 1,000 or 10,000 objects of the same type. for instance, when trying to display a list of the items, ideally I would like to be consistent with the objects I use, but where exactly should I run the query/get the data to populate the object(s) as running 10,000 queries seems wasteful. As an example, say I have a database of cats, and I want a list of all black cats, do I need to set up a FactoryObject which grabs the data needed for each cat from my database, then passes that data into each individual CatObject and returns the results in a array/object - or should I pass each CatObject it's identifier and let it populate itself in a separate query.

  • Do employers prefer software engineering over CS majors?

    - by Joey Green
    I'm in grad school at a university that was one of the first to have a software engineering accredited program. My undergrad is in CS. An employer recently recruited at our university and hired 5 SE majors. None of them were CS. Do employers prefer software engineering majors? The reason I ask is because I can focus on many different areas during my graduate studies and really want to take the classes that will help me land a great job. Right now I'm either going to use CUDA and parallelize an advanced ray-tracer for a graduate project or do research on non-photo-realistic rendering in augmented reality. Pursuing these would leave very little SE classes in my schedule. If I went the software engineering route, I would probably either do research into data-oriented programming or software design complexity. Sometimes I think when I'm 40 and look back will it matter at all? For some reason I'm thinking not.

  • Can't decide between Java or Python for college [on hold]

    - by Will Harrison
    I'm returning to college in about a month for Computer Science. My problem is, I have been programming on the web since I left (4 years ago), using PHP, ASP.NET, and JavaScript. I want to bone up on a more general purpose language that is cross platform before I begin. I would also like to be using a language that is common at my school and I know that they teach the students C++, Java, and Python. I would like to choose between Java or Python but I'm not sure which one. What do you think would be better based on job prospects in the next 2 years and community?

  • Approaching Java/JVM internals

    - by spinning_plate
    I've programmed in Java for about 8 years and I know the language quite well as a developer, but my goal is to deepen my knowledge of the internals. I've taken undergraduate courses in PL design, but they were very broad academic overviews (in Scheme, IIRC). Can someone suggest a route to start delving into the details? Specifically, are there particular topics (say, garbage collection) that might be more approachable or be a good starting point? Is there a decent high-level book on the internals of the JVM and the design of the Java programming language? My current approach is going to be to start with the JVM spec and research as needed.
