  • Best practices for managing deployment of code from dev to production servers?

    - by crosenblum
    I am hoping to find an easy tool or method, that allow's managing our code deployment. Here are the features I hope this solution has: Either web-based or batch file, that given a list of files, will communicate to our production server, to backup those files in different folders, and zip them and put them in a backup code folder. Then it records the name, date/time, and purpose of the deployment. Then it sends the files to their proper spot on the production server. I don't want too complex an interface to doing the deployment's because then they might never use it. Or is what I am asking for too unrealistic? I just know that my self-discipline isn't perfect, and I'd rather have a tool I can rely on to do what needs to be done, then my own memory of what exact steps I have to take every time. How do you guys, make sure everything get's deployed correctly, and have easy rollback in case of any mistakes?

  • Switch Gmail Icons Back to Text Labels

    - by Jason Fitzpatrick
    If Gmail’s icon-based buttons annoy you, it’s now possible to switch them back to the old text labels with a simple settings toggle. At MakeUseOf they highlight the new option in Gmail and how you can switch back to the old button layout: So how do you make that happen? All you have to do is click on the cog button, choose “Settings”, and go to the the General tab. Scroll down to find the “Button labels” setting, and change it from icons to text. I know what I’ll be doing shortly; text-based button labels here I come.

  • Noob-Friendly Guides to WSGI?

    - by Johnny McKenzie
    world! I have recently been delving into server-side code web development with python, and I have hit a brick wall; you see, I know little about server side code and HTTP (other than the v. basics with php shudder), and all of the docs for wsgi that I have found seem to be for people already well established in the field. Are there any n00b happy guides for server-side scripting (the theory of), or on wsgi out there. Http would be helpful, video tuts are also greatly appreciated. Thanks in advance.

  • A certain flash application causes a system crash

    It's no surprise I guess. Go here to try it! http://www.belgeler.com/blg/2hni/griffiths-introduction-to-electrodynamics-3-ed-solutions-manual It's wonderful, after a few seconds, top shows that our good friend plugin-container takes 83% of the physical memory (8 GB) before everything freezes and the PC doesn't respond. I'm using Ubuntu 12.04 and I have an nvidia (GTS 250) card with the "post-release updates" version of the driver. OFFTOPIC: Yes, it's the solutions manual. I'm self-studying so I don't have a professor to check my work. Please don't judge me :)

  • How to connect Nexus 7 with Ubuntu

    - by gotqn
    I want to move some files from my PC to Nexus 7. The tablet is connected to my PC's USB port and it is successfully charging. Unfortunately, the PC is not detecting the devices - what I expected is to be shown the Nexus 7 tablet as external devices (like my USB flash memory). As the tablet is connected to the my home internet network, I have checked if it will appear in the "Networks" section but it does not. I am using Ubuntu 12.4 LTS. Is there a easy way to connect the devices to my PC and move some information between them?

  • Intel HD graphics on Ubuntu

    - by tiax
    My girlfriend got a new Subnotebook for Christmas (Sony Vayo VPCY21S1E), which comes with an "Intel HD graphics" vga adaptor. When I try to boot the Ubuntu installer from USB, the screen goes blank after a short while, before I even see the Ubuntu logo. However, when I select "nomodeset" in the boot options, I can boot it to the CLI login prompt. When I start X, though, that only works in VESA mode (I've read Intel eventually got rid of Usermode Mode Setting and only offers KMS now, which I've disabled to get it to boot). What can I do to enable a) higher resolution than 1024x768 in VESA b) hardware acceleration for compiz, video playback, etc?

  • What is Atomicity?

    - by James Jeffery
    I'm really struggling to find a concrete, easy to grasp, explanation of Atomicity. My understanding thus far is that to ensure an operation is atomic you wrap the critical code in a locker. But that's about as much as I actually understand. Definitions such as the one below make no sense to me at all. An operation during which a processor can simultaneously read a location and write it in the same bus operation. This prevents any other processor or I/O device from writing or reading memory until the operation is complete. Atomic implies indivisibility and irreducibility, so an atomic operation must be performed entirely or not performed at all. What does the last sentence mean? Is the term indivisibility relating to mathematics or something else? Sometimes the jargon with these topics confuse more than they teach.

  • Weekend Project: Make Your Own Ferromagnetic Fluid

    - by Jason Fitzpatrick
    Experiments this simple and fun give you no reason to leave all science-based goofing off to the professionals: whip up a beaker of ferromagnetic fluid to capture magnetic waves in motion. The premise is simple: by combing a viscous liquid (in this case vegetable oil) with a magnetic powder (in this case MICR copy toner) and introducing a strong magnetic source (such as neodymium rare earth magnets), you can actually see the magnetic waves in physical space. It’s like the old magnetic filings on the table top trick, but in 3D. Check out the video above to see how you can mix up a batch of your own.

  • Looking for literature about graphics pipeline optimization

    - by zacharmarz
    I am looking for some books, articles or tutorials about graphics architecture and graphics pipeline optimizations. It shouldn't be too old (2008 or newer) - the newer, the better. I have found something in [Optimising the Graphics Pipeline, NVIDIA, Koji Ashida] - too old, [Real-time rendering, Akenine Moller], [OpenGL Bindless Extensions, NVIDIA, Jeff Bolz], [Efficient multifragment effects on graphics processing units, Louis Frederic Bavoil] and some internet discussions. But there is not too much information and I want to read more. It should contain something about application, driver, memory and shader units communication and data transfers. About vertices and attributes. Also pre and post T&L cache (if they still exist in nowadays architectures) etc. I don't need anything about textures, frame buffers and rasterization. It can also be about OpenGL (not about DirecX) and optimizing extensions (not old extensions like VBOs, but newer like vertex_buffer_unified_memory).

  • Which of the following relational database management systems would a company adopt (for migration), if any, MS Access, MS SQL Server or MySQL?

    - by Hassan Hagi
    Dear programmers, as part of my final year university project, I am conducting research into relational database management systems such as Microsoft Office Access 2007, Microsoft SQL Server 2008 and MySQL 5.1. The description does not need to be detailed however; I am trying to find empirical evidence and professional opinion/fact to determine which of the three databases are best suited for the required size of company (stated or unstated). OS: Microsoft windows (XP or newer) Please consider the following, but full details are not necessary: Memory management Migration Design constraints Integrity (data and others) Triggers User constraints Ease of use Performance Crash Recovery (not the operating system) Total Cost of Ownership (TCO) Also any info on Open source (to do with the three RDBMS) Thank you for your time and help.

  • Willkommen in der Cloud. Aber nur mit den richtigen Standards.

    - by A&C Redaktion
    Cloud Computing ist das „In"-Thema, über das Anwender, Partner und Anbieter gleichermaßen heiß diskutieren. Reinhard Arnhold, Director Channel Sales, ist ein echter Kenner der Materie und zeigt im Video die unterschiedlichen Perspektiven auf, die ein ISV einnehmen kann. Die Geschäftsmodelle erfahren durch die Möglichkeit des Cludcomputings eine neue Dimension. Für welches Modell sich ISVs hierbei auch entscheiden, den richtigen Standard bei der Lösungsarchitektur zu wählen, das ist, so Reinhard Arnhold, eine der wichtigsten Erfolgsvoraussetzungen. Für ISVs, die aktuell noch keine Cloud Computing-fähigen Anwendungen haben, hat Reinhard Arnhold eine gute Botschaft. Oracle ist vorbereitet, mit der standardisierten Oracle Architektur den ISVs den Weg in die Cloud zu bahnen. Erlauben Sie ein kleines Wortspiel: Das ist der „Stairway to heaven". Es kann also ganz einfach sein, den geschäftlichen Himmel durch die Cloud zu erreichen.

  • A Closed Mind Killed the Retail Star

    Im on the plane flying back to New Zealand and Im astonished how quickly things have changed since I was last in the US. This trip I visited LA, Las Vegas and San Francisco and I was overwhelmed by the change that I witnessed in 12 short months. This morning following my memory map I headed towards the large  CompuServe electronics store in downtown San Francisco where my wife and I brought a digital camera in 2006. Homing in on the spot I was disappointed to see it had turned into yet another...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Are certification courses worth it?

    - by Bill Williams
    I'm planning on getting certification in Database Development for SQL Server (MSTC - 70-433). I'm a junior level report writer at a new job and the company is offering to pay the majority, if not all, of training course fees. The course is five days. I noticed that MS has a self-paced training kit (book) that I could use. I'm wondering if this would be a better option because it will allow me to go as quick as possible. I've also heard about video training sessions (Lynda.com) but they seem to go at slow pace. My questions are: What should I expect at a certification course? Is it hands-on training? Small classes with personal feedback or not? Would I be better off learning at my own pace using the training kit? (I'd rather this not turn into a certifications are pointless discussion..)

  • Day 1 - Finding Like Minds

    - by dapostolov
    So, is being a Game Developer any different from being an IT Developer? I picture a poorly lit environment where I get to purchase my own desk lamp; I'm thinking one of those huge lava lamps that pump out so much heat you could fry an egg on it. To my right: a "great wall" of empty coke cans dwarf me. Eating my last slice of pizza I look across my desk to see a fellow developer with a smug look on his face;  he's just coded his latest module for the game and it looks like he's in nirvana. My duty, of course, is to remind him to keep focused on the job at hand. So, picking up my trusty elastic and aerodynamically crafted paper bullet I begin a 10 minute war of welts and laughter which is promptly abrupted by our Project Manager demanding more details from our morning Scrum meeting. After providing about 5 minutes of geek speak and several words of comfort to make his eyes glaze over...it hits me, the idea for the module...beckoning my developer friend over, we quickly shoo the Project Manager away and begin our brainstorming frenzy ... now, where'd I put that full can of coke? OK. OK. This isn't probably the most ideal game developer environment, but it definitely sounds fun to me...and from what I gather is nothing like most game development companies. But I'm not doing this blog series to "go pro"; like I stated in my first post I want to make a 2D game from an idea my best friend and I drummed up long, long ago. I'm in this for the passion AND I want to see how easy it is for us .Net Developers to create a game. So where do I start? Where can I find like minded individuals? What technologies are there? What do I need to make a video game? The questions are endless....AND...since I already have an idea ... lets start with ... Technology (yes, I'm a geek, live with it...) Technology OK. Predominantly, games are still made in C++ or even C. I'm not sure how much assembly code is floating around lately, however, that is not my concern. I do know C / C++ from my past, enough to even get me by, but I'm mainly interested in a recent, not-so-new, technology called XNA. What is XNA? XNA allows us .Net Developers to make 2D / 3D games for windows, Xbox*, and Windows Mobile 7*. * = for a nominal fee *cough* The following link is your one stop shop to XNA game development: http://creators.xna.com/en-US/education/gettingstarted The above site hosts information such as: - getting started - a sample/instructional shooter game in 2D / 3D with code (if I'm taking too long for you in this blog series) - downloads - starter kits... http://creators.xna.com/en-US/education/starterkits/ And of course...forums. You can also subscribe and pay for their premium membership which gets you some pretty awesome tutorials, resources, downloads, and premium community support. Some general Wiki information about XNA: http://en.wikipedia.org/wiki/XNA_%28Microsoft%29 Community Support OK. Let's move on to industry and community support. Apart from XNA, there are some really cool sites out there, I just haven't found all of them yet. However, I found a really cool Game Development website called Gamastura. You can click on the following link to get you there: http://www.gamasutra.com/ The site is 100% dedicated to "The Art & Business of Making Games". Armed with blogs, twitter, jobs/resumes and most importantly industry news; one could subscribe to the feed and got lost in the wealth of information it provides. On a side note: I remember Gamasutra being around when my best friend and I wanted to make a video game...meaning, they've been around for a while now. I think the most beneficial aspect of this site is to understand the industry you want to get into. Otherwise, it's just a cool site to keep up to date with the industry in general. Another Community Support option is LinkedIn. Amongst the land of extremely bloated achievements and responsibilities lay 3 groups (that I have found) that deal with game development.: http://www.linkedin.com/groups?gid=59205 - Game Developers http://www.linkedin.com/groups?gid=824817 - DirectX Game Developer Network http://www.linkedin.com/groups?gid=756587 - DirectX Developers The Game Developers group in LinkedIn is by far the most active of the three and could possibly provide a wealth of support. What I've done thus far: - I lightly researched the XNA technology - I looked around for some community sites to assist me - I downloaded the XNA Game Studio 3.1 on my PC and installed it on my IDE - I even tried both tutorials! http://creators.xna.com/en-US/education/gettingstarted/bgintro/chapter1   Best Regards D.

  • Azure Blob storage defrag

    - by kaleidoscope
    The Blob Storage is really handy for storing temporary data structures during a scaled-out distributed processing. Yet, the lifespan of those data structures should not exceed the one of the underlying operation, otherwise clutter and dead data could potentially start filling up your Blob Storage Temporary data in cloud computing is very similar to memory collection in object oriented languages, when it's not done automatically by the framework, temp data tends to leak. In particular, in cloud computing,  it's pretty easy to end up with storage leaks due to: Collection omission. App crash. Service interruption. All those events cause garbage to accumulate into your Blob Storage. Then, it must be noted that for most cloud apps, I/O costs are usually predominant compared to pure storage costs. Enumerating through your whole Blob Storage to clean the garbage is likely to be an expensive solution. Lokesh, M

  • How to refactor an OO program into a functional one?

    - by Asik
    I'm having difficulty finding resources on how to write programs in a functional style. The most advanced topic I could find discussed online was using structural typing to cut down on class hierarchies; most just deal with how to use map/fold/reduce/etc to replace imperative loops. What I would really like to find is an in-depth discussion of an OOP implementation of a non-trivial program, its limitations, and how to refactor it in a functional style. Not just an algorithm or a data structure, but something with several different roles and aspects - a video game perhaps. By the way I did read Real-World Functional Programming by Tomas Petricek, but I'm left wanting more.

  • Car Modelling for race game

    - by Mert Toka
    I am taking Computer Graphics course this semester and we have a video game competition. I am making racing game with simulated dynamics. Our professor told us that we don't have to do much of a modelling but since we haven't started the gaming part and since I have free time I want to model the car. My question is firstly which software do you recommend to design game components? I know Maya right now. Secondly, if I design the car or any other part, what should its polygon count in order to run game smoothly? I can design pretty much everything but I assume that it is hard to design low-poly models.
