  • JSP Model 2 Architecture and Dependency Injection

    - by Robert
    If I'm writing a web application that uses the model 2 architecture, is it possible to use the Google Guice framework (or really any IoC container)? The reason I ask this question is because everything I've researched about DI, IoC, et cetera always uses Spring, Hibernate or some other framework/container in their examples. I'm just using Java classes, controllers, and JSP's to build this application and I can't find any good documentation about the subject.

  • High-Powered Sites for low Cost

    - by HighAltitudeCoder
    Ahh, I am experiencing the intimidation of my very first post - visible by the whole world. Ok, here goes.   This first post is nothing exceptional.  It is simply a recommendation based (fittingly, I suppose) upon the job search you may be gearing up for.  I find myself in this very situation right now.  And, I will take my own recommendation after posting this entry. Job-Seekers: To the left you will notice two links under "Recommended Learning".  I have found these links to be invaluable when it comes to re-tooling, re-familiarizing, or otherwise resharping my skills when looking for that next job. Often, you will find job-postings with the text, usually posted after a laborious list of qualifications indicating the company's desire to hire candidates who know what they are doing: "...Looking for a candidate who can hit the ground running...".  The interesting thing about this post to me is I've encountered many individuals who, after speaking and working with them for some time, I've realized are perfectly capable of hitting the ground running - and FAST.  But what if they speed off in the wrong direction? The next time you spearhead a major task in your job, ask yourself: Am I headed in the wrong direction?  There are many ways to do this.  In fact, I've found in this new field there are more tempting ways to steer your project in the wrong direction than there are good ones.  I don't want to suggest that every one of my posts will fall into the "right direction" category, however I do think a healthy dose of introspection of the pros and cons will always be beneficial before you set off. That said, allow me to expound on the previously mentioned links. These web sites are invaluable.  They demonstrate the capabilities of existing as well as new and upcoming tools available in several IDE's.  I've viewed many tutorials in LearnVisualStudio.NET, and only one or two so far in TrainingSpot, however I've been delighted in their simplicity and straightforward approach to proper usage of the particular tool or concept being discussed.  They have not (so far in my experience) demonstrated ways in which to use the tools that become cumbersome, impractical, or error-prone. Each website has step-by-step videos that can be paused, replayed, and most importantly, they are done in real time.  As the author is typing, the viewer gets to experience the coding experience from a first-person perspective, including syntax errors, unexpected behaviors, IDE setup idiosyncracies, everything.  A subtle value I've gained from these videos is that a certain degree of confusion and introspection is normal when working with new tools and exploring new paths.  They (as well as your own experience) are not to be feared, but enjoyed.  I highly recommend them. Good work, guys!

  • Estimates, constraint and design [closed]

    - by user65964
    For your next two software projects (assuming that you're getting programming assignments, otherwise consider the program to find the min and max of a set of rational numbers) estimate how much effort they would take before doing them, then keep track of the actual time spent. How accurate were your estimates? State the requirements, constraint, design, estimate (your original estimate and the actual time it took), implementation (conventions used, implement/test path followed.

  • What is lightweight lock in distributed shared memory systems?

    - by Kutluhan Metin
    I started reading Tanenbaum's Distributed Systems book a while ago. I read about two phase locking and timestamp reordering in transactions chapter. While having a deeper look from google I heard of lightweight transactions/lightweight transactional memory. But I couldn't find any good explanation and implementation. So what is lightweight memory? What are the benefits of lightweight locks? And how can I implement them?

  • Which is better a computer science degree or a Software engineer degree?

    - by Shadow wolf
    I'm asking here so since you all have experience in or around game programming, that's what I want to do, and I’m trying to find as many options as I can before my senior year, which is next year. So do you have any opinions on the matter of which would give me a better education in programming? Please no talking about anything other than the two degrees because I know of game programming degrees out there but I like to see which of these would provide the best alternate choice.

  • Search For a Query in RDL Files with PowerShell

    - by AllenMWhite
    In tracking down poorly performing queries for clients I often encounter the query text in a trace file I've captured, but don't know the source of the query. I've found that many of the poorest performing queries are those written into the reports the business users need to make their decisions. If I can't figure out where they came from, usually years after the queries were written, I can't fix them. First thing I did was find a great utility called RSScripter , which opens up a Windows dialog...(read more)

Do you know where I can find this kind of licence text ?

  • How can I get magnet links for Ubuntu?

    - by badp
    Torrent files are being increasingly scrapped for magnet links, "mini torrent files" in concise and plain-text form that can be simply copy pasted around. Those link to the actual .torrent file "in the BitTorrent cloud", without relying on servers that may be temporarily overtaxed ("OMG NEW UNBUNT MUST GET NAO") or simply offline. Does Canonical offer magnet links for their Torrent distributions? Where can one find them?

  • Declaring variables in SQL

    I would like to blog more about the problems I encounter on a daily basis.  I find that taking 10 minutes or so to write a simple solution to my problems helps me retain that information.

  • Ubuntu 12.10 Crashing Compiz/Unity (not Nvidia related)

    - by iamronen
    I've upgraded from 12.04 to 12.10 and compiz and/or unity are constantly crashing rendering my computer useless (no top bar, no dash, no window decorations). I have just discovered that when I login with the guest account everything seems to be working OK. I've been through all the threads I could find and haven't found a resolution. This isn't Nvidia related (I am running on a System76 laptop with ATI Radeon). Is there any way I can go about isolating the problem and restore my user account?

  • Question about design

    - by lukeluke
    Two fast questions about two design decisions: Suppose that you are checking collisions between game elements. When you find a collision between object 1 and object 2, do you play immediately a sound effect or do you insert it in a list and, in a later a stage, do you process all sound effects? Same question as above for user input. When the user presses key 'keypad left' do you insert the event in a queue and process it later or do you update character position immediately? Thx

  • Need Help with partitions and such Dual Booting 13.10 w/ windows 7

    - by Aymax
    so I've spent the past couple days freaking out about this and looking for answers, and I decided to resort to asking on forums. probably should have before I wasted 2 entire days. so I am trying to DUAL-INSTALL Ubuntu 13.10 with my x64 Windows 7 home premium computer. I have 6 gb of ram, 1TB hard drive, and a 3.3GHZ dual core processer (just in case it matters). I've managed to figure some things out. I've burned the ubuntu files onto a DVD, and I have been able to successfully run it off the disk. I also shrunk my Windows partition by 120Gb and partitioned that for Ubuntu (all using the windows Disk Manager). Problems: When I turn my computer on with the DVD in the tray, the computer cant find windows. it flashes a screen real quick that says something about not being able to find an operating system, and then goes to "grub" and asks what i want to do with Ubuntu. this scares me, because I don't know if that means that I will not be able to boot windows if I install Ubuntu. The Ubuntu 13.10 installer does not detect my Windows operating system. I only have the options to Erase everything on my drive, or "something else." I choose that, which brings me to 3 I don't understand the partition table. I have no idea which drive im selecting to install stuff on, much less which one to select. I tried to tell by the amount of memory partitioned off, but none of the numbers seem to be accurate. Plus, all the names are dev/sda(#). I know Ubuntu knows the name of my partition, because on the sidebars it shows the names of the different drives, including the partition I made; so why don't they use the names? I have no idea what I'm going to be erasing. I've read that I should know which is which by the file system type, but they are all NTFS, including the one I made. my only other option was FAT, none for EXT2 or any of that like people said to do. My main concerns are that of accidentally erasing windows or not being able to access windows. any feasible solution is helpful, weather it helps me with the install or to make Ubuntu see windows. I realize this question has been asked much, but i have found no feasible answers so far. I am relatively new to this, and have never installed an operating system before, so I do not know most of the jargon. please keep it relatively simple, please. I am not a programmer. Thanks.
