  • Importance of certifications for Java programmer without BS degree?

    - by programmx10
    I've read some posts here and other places about how a lot of people don't put much value in certifications but I am beginning to think it may be necessary for me at this point to be able to move to a bigger company, etc. I currently work as a Java programmer with a startup and worked with a small company before that. Now that I'm applying with larger companies the hr people / recruiters have been asking a lot about certifications and some have directly suggested that someone in my position should probably get a few (they were trying to be helpful) since I haven't completed a BS degree yet (I bounced around a bit in college and ended up not finishing but have enough units to finish eventually, just its not something I can do nearly as easily as getting certifications). Anyways, just curious about what people think for someone in my situation where I do have an interested in working for large companies and do not currently have a BS degree (but do have experience already in the field). Any advice on which certifications beyond the SCJP would be appreciated as well

  • Trip Report: Scottsdale Arizona Event Conference Planning

    Monday May 10th, 2010 represents my largest and best event to-date, that I have ever hosted. For the last seven years, I’ve grown a technical audience around Microsoft programming / developers in the Phoenix area. Some travel from California, New Mexico, and other parts of Arizona, but for the most part the crowd is local. In years past, this all day event has been as small as 300 folks, and as large as 500, and I’ve tried been to venues around the valley some better than others. This...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • How can I instruct nautilus to pre-generate thumbnails?

    - by Glutanimate
    I have a large library of PDF documents (papers, lectures, handouts) that I want to be able to quickly navigate through. For that I need thumbnails. At the same time however, I see that the ~/.thumbnails folder is piling up with thumbs I don't really need. Deleting thumbnail junk without removing the important thumbs is impossible. If I were to delete them, I'd have to go to each and every folder with important PDF documents and let the thumbnail cache regenerate. I would love to able to automate this process. Is there any way I can tell nautilus to pre-cache the thumbs for a set of given directories? Note: I did find a set of bash scripts that appear to do this for pictures and videos, but not for any other documents. Maybe someone more experienced with scripting might be able to adjust these for PDF documents or at least point me in the right direction on what I'd have to modify for this to work with PDF documents as well.

  • New MyOracleSupport (MOS)Interface Coming 13 July 2012

    - by user793553
    On July 13, 2012, we plan to upgrade the My Oracle Support HTML-based user interface (UI) with additional functionality that will allow those users remaining on the Flash-based user interface to switch over to the HTML version. Our goal is to provide a single-online support portal so that all My Oracle Support users can benefit from the same features and functionality. Prior to July 13, 2012, users of Oracle On Demand, Oracle CRM On Demand, Taleo, and Oracle Configuration Manager should continue accessing the My Oracle Support Flash-based user interface. After July 13, 2012, the above features and functionality to support these users will be available on the HTML interface. All other users of My Oracle Support can make the switch now. Benefits of using the HTML-based user interface include: Streamlined, three-step process for initiating new Service Requests (SRs) Single, consistent workflow for both hardware and software incidents Enhanced personalization and filtering within the user interface New accessibility features (enabling screen readers, large fonts, etc.) Additionally, please note Internet Explorer 6 (IE6) will no longer be supported. For further information, please check Doc ID 1385682.1

  • Is there a correlation between complexity and reachability?

    - by Saladin Akara
    I've been studying cyclomatic complexity (McCabe) and reachability of software at uni recently. Today my lecturer said that there's no correlation between the two metrics, but is this really the case? I'd think there would definitely be some correlation, as less complex programs (from the scant few we've looked at) seem to have 'better' results in terms of reachability. Does anyone know of any attempt to look at the two metrics together, and if not, what would be a good place to find data on both complexity and reachability for a large(ish) number of programs? (As clarification, this isn't a homework question. Also, if I've put this in the wrong place, let me know.)

  • C++ compiler structures such as Virtual method Table etc

    - by Roger
    I am aware of the C++ Virtual Table which allows dynamic dispatch for doing things at runtime (although if I am honest I am not completely sure of the full list of things it achieves). I am wondering what other "low level" aspects of C++ are there, which one doesnt usually come across when learning the C++ language? Things like: -How is multithreading and locking on objects performed? -Overloading/overwriting functions -Generics Are there other "structures", similar to the vtable, which assist with these types of things on a lower level? (and if anyone can help with what the VTable actually does it would be most appreciated!)

  • LightScythe Creates Huge Light Paintings

    - by Jason Fitzpatrick
    Earlier this year we showed you how an LED POV staff could be used to visualize network data. This build takes it to another level and allows you to imprint entire words and images into photos. Gavin, a hardware hacker from Sydney, built an open-source POV (persistence of vision) staff after the Wi-Fi visualizer inspired him to begin playing with large POV builds. He built his POV staff using LED strips, wireless controllers, and a laptop to send the signals at the proper intervals to the staff. He can write words, create images, and even send Pac-Man racing across the frame. Hit up the link below to read more about his project and grab his schematics and parts lists.

  • How to calculate Sin function quicker and more precisely?

    - by user1297181
    I want to calculate y(n)=32677Sin(45/1024•n), where y is an integer and n ranges from 0 to 2048. How can I make this process quicker and more precisely? Now I want to show you a reference answer: Since Sin(a+b)=Sin(a)Cos(b)+Cos(a)Sin(b) And Cos(a+b)=Cos(a)Cos(b)-Sin(a)Cos(b). So I can store Sin(45/1024•1) andCos(45/1024•1) ` only.Then use this formula: Sin(45/1024•2)=Sin(45/1024•1+45/1024•1), Cos(45/1024•2)=Cos(45/1024•1+45/1024•1), .... `Sin(45/1024•n)=Sin(45/1024•(n-1)+45/1024•1) `, `Cos(45/1024•n)=Cos(45/1024•(n-1)+45/1024•1) `, This way maybe quicker without storing large array.

  • Is possible to write too many asserts?

    - by Lex Fridman
    I am a big fan of writing assert checks in C++ code as a way to catch cases during development that cannot possibly happen but do happen because of logic bugs in my program. This is a good practice in general. However, I've noticed that some functions I write (which are part of a complex class) have 5+ asserts which feels like it could potentially be a bad programming practice, in terms of readability and maintainability. I think it's still great, as each one requires me to think about pre- and post-conditions of functions and they really do help catch bugs. However, I just wanted to put this out there to ask if there is a better paradigms for catching logic errors in cases when a large number of checks is necessary.

  • Who uses GnuSTEP?

    - by adib
    This has been a big question lurking at the back of my head. From what I see, GnuSTEP nowadays is primarily a "hobby" project of a small but tightly-knit group of people. However I haven't seen a large commercial (off-the-shelf) application that uses it, apart from the small applications that comes with the GnuSTEP distribution. Heck, since even Ubuntu doesn't really use it then is GnuSTEP really more than being a "hobby" framework? I know that Sony's SNAP at one brief moment uses GnuSTEP, but they killed the platform before it can do anything meaningful.

  • How to give parallax backgrounds more depth

    - by user28015
    I have 3 tiled images of some sort of galaxy/space in the background of a 2D Game: The first one has an alpha of 100%, the second an alpha of 80% and the last one has an alpha of 60%. I scroll the the one in the background slower than the other ones of course. classic parallax. In the foreground I have some particles flying towards the player to simulate some dust / stars flying by. (I know that stars don't fly by, but I think we all have seen this in a lot of games). But I can't quite achieve the depth effect I am looking for. I want it to look "deeper". I did read something about using blending modes for the backgrounds, but that would require to render them as objects right? So the question is: What is a good technique to do a scrolling parallax background in GameMaker?

  • XNA: Runtime differences in ClickOnce install versus development version

    - by Sean Colombo
    I have a game written in XNA, and I use ClickOnce installers to distribute the game to testers. I keep once computer as a test machine which does NOT have development environments installed, so that I can test the installed version. We've found a reproducible bug in our game, but the bug ONLY occurs on the non-development machines that use the ClickOnce installer. The bug is related to some of our code for moving around 3D objects and is not tied to Networking or GamerServices. Are there known differences in the ClickOnce runtime and the version on dev? Are there any best-practices for debugging something like this?

  • What are some alternatives to ASI iMIS Content Management Systems? [closed]

    - by SLY
    Possible Duplicate: Which Content Management System (CMS)/Wiki should I use? I am working with a team to select a new content management system for a large membership organization (around 25,000 members). The organization has revenue so I'm not looking for a dirt cheap solution. The site currently uses ASI iMIS which is based on ColdFusion. It's difficult to work with and not flexible for our needs. What other possible alternatives to ASI iMIS are there? Ideally the solution would have some sort of support from the vendor. So far I've come up with: Drupal/Acquia SDL Tridion Plone Ellington (probably too news like) Pinax (probably not developed enough)

  • assistance recovering/reinstalling/installing ubuntu and win7

    - by razzrat
    New computer with Windows 7 installed, I defrag, shrink, re-boot from Ubuntu LiveUSB, go to gparted and look at partitions before installing Ubuntu....for some reason Win7 is still taking up 400G of my HD! I resized partition down with gparted, exit and yes of course I can't boot into Windows. When I go to install Ubuntu in new large unallocated space I get a blank screen at the point you are asked what kind of installation you want. I have Ubuntu 12.04 LiveUSB, Windows 7 re-installation disk and driver disks also. The HDD currently has 3 allocated partitions: 'diag' fat16, 'recovery' ntfs and 'OS' ntfs which has a red '!' next to it.

  • Threading iPhone

    - by bobobobo
    Say I have a group of large meshes that I have to intersect rays against. Assume also, for whatever reason, I cannot further simplify/reduce poly check count by spatial subdivisioning. I can do this in parallel: bool intersects( list of meshes ) // a mesh is a group of triangles { create n threads foreach mesh in meshes assign to a thread in threads wait until ( threads.run() ) ; // run asynchronously // when they're all done // pull out intersected triangles // from per-thread context data } Can you do this in ios for games? Or is the overhead of thread creation and mutex waiting going to beat-out the benefit of multithreading?

  • How should I choose quadtree depth?

    - by Evpok
    I'm using a quadtree to prune collision detection pairs in a 2d world. How should I choose to what depth said quadtree is calculated? The world is made mostly of moving objects1, so the cost of dispatching the objects between the quadtree cells matters. What is the relationship between the gain from less collision checking and the loss from more dispatching? How can I strike a balance that performs optimally? 1 To be completely explicit, they are autonomous self-replicating cells competing for food sources. This is an attempt to show my pupils predator-prey dynamics and genetic evolution at work.

  • How important is to avoid name collisions between libraries belonging to different domains?

    - by Sergio
    I have written a small open source Java library for facilitating conversions between different types of objects (in the style of Google's gson, but quite more general). It seems to me that a nice natural name for my library is JConverter, after browsing in the web to see if another library with the same name already exists, I found a library with the same name for Joomla. My concrete question is: How important is to avoid naming collisions when creating an open source library if an existing library with the chosen name already exists in a complete different domain ? (in my concrete case, these are libraries even implemented for different languages).

  • Gnome 3 and compiz, everything works except Explode and Leaf Spread animations

    - by Erik
    I am using 11.10 with Gnome 3, I have installed Compiz, and have got it functioning almost how I want it. I want my windows to Leaf Spread, which seems to work fine for a few minutes after I enable it and restart my machine. However, over the time of a few window closes, I notice that the objects are not showing up little by little until the Leaf Spread just doesn't show at all? This really isn't a big deal, but I'd like things to work properly. Can anyone shed some light on this?

  • How can I neatly embed Flash in a page in a way that is cross-browser compatible?

    - by Mark Hatton
    When I receive Flash objects from my designer, it comes with an example HTML page which includes both <object> tags and <embed> tags as well as a whole heap of JavaScript. If I copy and paste this code in to my webpage, it works, but the code looks a mess (and there is so much of it!). If I remove the extra code and try either just <embed> or <object> on their own, it works in some browsers, but not others. Is there a neat, minimal method that works in all the major browsers?
