• What is Cyber Monday? [Infographic]

  - by Jason Fitzpatrick

  Nearly everyone is familiar with Black Friday, the massive shopping day right after Thanksgiving, but Cyber Monday is a recent invention. Check out this infographic for the low down. Cyber Monday is only a scant six years old, an invention of online retailers looking to create a shopping day to compete with the in-store frenzy of Black Friday. Although quite a few retailers offer online Black Friday deals, Cyber Monday is a the biggest day for online deals–many shoppers fail to find the things they were looking for on Black Friday and turn to online sources.

• Spring can commit Transaction in finally block with RunTimeException in try block [migrated]

  - by Chance Lai

  The project used Spring + Hibernate Sample code: public void method(){ try{ dao.saveA(entityA); throw RuntimeException; dao.saveB(entityB); }catch(RuntimeException e){ throw e; }finally{ dao.saveC(entityC) } } Finally, just entityC will be saved in database in test. I think saveA, saveB, saveC in the same transaction,they should not be committed. In this case, I want to know why entityC is committed. How does Spring do this in the finally block?

• How do you put a database online?

  - by Dezrik

  I have a very beginner question regarding web development. I've had some experience with JSP, Hibernate, and MAMP to create a simple system for tracking inventory and sales. But this was all done locally on one computer. This time, I want to create a system that could be accessible online. It's to help my mother track her business wherever she goes. So there would be similar aspects like tracking inventory and sales. I understand that you have to have a server in which to host all the files in. But I don't understand how you can access your database online. Or what sorts of applications or products should be used. Currently the host of my database is localhost. How do put it online such that you can still do CRUD operations? Are there any guides to do this?

• OWSM vs. OEG - When to use which component - 11g

  - by Prakash Yamuna

  A lot of people both internal to Oracle and customers keep asking about when should OWSM be used vs. OEG. Sometime back I posted Oracle's vision for layered SOA security Here is a quick summary: Use OWSM in Green Zone Use OEG in Red Zone (DMZ) If you need end-to-end security in which case they will want both OWSM and OEG. This is the topology I would recommend for most customers. If you need only Green Zone security - then use OWSM in conjunction with Oracle FMW products like SOA Suite, OSB, ADF, WLS, BI, etc both on the Client Side and Service Side (assuming you are using FMW technologies for both Clients and Services). If you need only Red Zone security - then use OEG on the Service Side. You can use OWSM for the Client Side if you are using FMW to build your clients.

• Can't access Windos 7 OS in Ubuntu

  - by Myers

  When I try and Access my Windows 7 OS I get the following memo and I have no idea what to make of the code. Error mounting /dev/sda2 at /media/name/Windows7_OS: Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,dmask=0077,fmask=0177" "/dev/sda2" "/media/name/Windows7_OS"' exited with non-zero exit status 13: ntfs_attr_pread_i: ntfs_pread failed: Input/output error Failed to read NTFS $Bitmap: Input/output error NTFS is either inconsistent, or there is a hardware fault, or it's a SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows then reboot into Windows twice. The usage of the /f parameter is very important! If the device is a SoftRAID/FakeRAID then first activate it and mount a different device under the /dev/mapper/ directory, (e.g. /dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation for more details. What should I do ?

• Would you make your website's source code public?

  - by Karpie

  Back story: My best friend is a self-taught coder for a community art site, written in PHP. Some time ago he mentioned he wanted to make the source code of the site public, to which my response was total horror - surely it was going to be full of security holes waiting to be found, and it was going to lead to hacking and errors on a huge scale. He never ended up doing it. Current story: I'm starting development of a community website built in Rails, and for ease of use I was going to use Github for version control. Then I realized it was pretty much exactly the same thing as my friend making his source code public - which made me stop and think. Would you make your website's completely-custom source code public? Or is this a case of open source gone too far? (note: I don't think this applies to people who run things like Wordpress. Or does it?)

• Unable to boot either Ubuntu or Windows after kernel panic

  - by Josh Taylor

  Hi, Today I have been unable to boot into my Ubuntu (10.10) or Windows (7) partition. Ubuntu kernel panics on boot with the error: init: hash.c:296: Assertion failed in nih_hash_search: hash != NULL I can boot into a LiveUSB environment, and from there can access all my files on my 3 partitions (1 ext4, 2 NTFS). I have also ran fsck on the ext4 partition and ntfsfix on the 2 NTFS partitions, both not finding any errors at all. And Grub is intact and have also tried a reinstall of it. So at the moment I'm currently stuck using a LiveUSB, and would like to see if there are any other options other than reinstalling. Thanks. Update I've now ran chkdsk using my Windows recovery disk, and it found errors and fixed them, but I am still unable to boot into either Windows or Ubuntu Update #2 I've decided to just re-install Ubuntu and start again as I didn't really want to spend any more time looking around whilst I need this computer for work. Thanks for all your help though.

• How can I get pictures from Shotwell on the notebook to the desktop?

  - by Meng Tian

  My father has a desktop and a notebook. The desktop is way more powerful and has RAID set up, so he uses it for editing and storing his pictures. But he spends several months a year away from home. So he has a notebook for this. He imports the pictures into shotwell on his computer. He likes to organise his pictures on the notebook already, by creating and naming the right events, deleting pictures and sometimes editing a bit. When he is back home, he wants to get his pictures on the desktop, without losing the names of the events in shotwell. Sadly, one cannot merge two shotwell databases, nor is it possible to import another database. Do you know any way, I can manage this? Or did I just miss something?

• Looking for a light weight note program.

  - by Erin

  This might belongs on superuser but for me it's part of programming so i will ask it here. I find I use notepad to keep chunks of data that are important but not important enough to keep in my head. The one problem with this is I end up with a lot of files on my desktop that I don't know what they are for, or I don't save the file and my computer gets rebooted for some reason. So that big ramble leads to the question. I am looking for a note taking system that is light weight and easy to manage. I would rather it not be a huge application like onenote but if that is what you are using and is is working well for you could you explain how you are doing it? Thanks Erin.

• Google is not treating two Austrailian schools as separate sites when both are subdomains of qld.edu.au

  - by LuckySpoon

  My question relates to two websites, each of which is a "Calvary Christian College", however in two totally different locations and unrelated to each other entirely (except by name, and domain). All schools in the state are issued a .qld.edu.au, in this case calvary.qld.edu.au and calvarycc.qld.edu.au. Now what's interesting is that these domains are crossing each other in sitelinks for searches such as "calvary christian college townsville" (if you check the sitelinks 2/6 are to a different domain). I've put a demotion in for this ages ago (we control calvary.qld.edu.au), however we're seeing no change on the results page. I have been able to get the owners of calvarycc.qld.edu.au to submit demotions for our domain, which should go in sometime this week. What can we do to tell Google that these websites are not interchangeable, despite both appearing as "subdomains" of qld.edu.au. We can possibly open channels of communication with the administrators of qld.edu.au but will need to tell them what we need to change, and at this point I'm out of ideas.

• Screen Lag/Running Slow

  - by Nick M

  I am having trouble with Ubuntu 12.10. Everything is working fine, although there is a slight problem. It seems to lag every once in a while, as in I will move the mouse, then about two seconds later the cursor will actually move on the screen. Is there any way to fix this? This is my first day using Ubuntu and I put it on a computer I built myself. I don't have much experience so a detailed answer would be very much appreciated.

• Unable to recognize hard drive after replacing a drive

  - by Peter Schriver

  I have a Poweredge 830 that I had been using with 1 OS Sata drive and 3 data drives. One of the drives had some failing sectors so I replaced it with a different drive. For some bizarre reason the computer would not reboot so I disconnected all of the media drives and did a clean reinstall on the OS drive. Only the boot drive and one of the media drives are now recognized by my Bios. Drive 0 and 2. Drive 1 and 3 are listed in the Bios as "Unkown Device" Any help would be appreciated I think there may be something wrong with the install. For some reason when I attempt to change the display it says I have a laptop.If you think a reinstall is in order I will try that.

• Checking is sides of cubes are solid

  - by Christian Frantz

  In relation to this question: http://gamedev.stackexchange.com/a/28524/31664 And a question I asked earlier: Creating a DrawableGameComponent And also because my internet is too slow to get on chat. I'm wondering how to check if the sides of a cube are solid. I've created 12 methods, each one creating indices and vertices for sides of a cube. Now when I use these methods, the cube creates how it should. All 6 sides show up and its like I didnt change a thing. How can use if statements to check if the side of a cube is solid? The pseudocode from the question above shows this: if(!isSolidAt(x+1,y,z)) verticesToDraw += AddXPlusFace(x,y,z) But in my case is would be: if(!sideIsSolid) SetUpFrontFaceIndices(); My method simply takes these index and vertex values and adds them to a list indicesToDraw and verticesToDraw, as shown in the answer above

• Hardware Compatibility

  - by thebradnet

  I am looking into buying a LENOVO RD330 SERVER with a ThinkServer RAID 500 Adapter II RAID controller. I am having problems finding out if all of the hardware that I am wanting will be compatible with Ubuntu. I have check the "Certified Hardware" list but the list is very limited. Both the computer and the RAID controller say they support RedHat and Suse but obviously Ubuntu isn't mentioned. I have talked with my vendor and they also not certain if this hardware will work. I have also Google around and the RAID controller appears to be an LSI chipset. But again I haven't been able to find any definitive information saying that this will work. Any suggestions on how I can find out if the hardware will work?

• What to do?! Upgrading from 12.10 to 13.04 failed :(

  - by Jon Ramirez

  I got an update reminder to go from 12.10 to 13.04. I followed the instructions, was able to download the package, and started installing. Up to a point where my computer (seemed to) restart and there was just a black screen (with the backlight on) for more than an hour. Then I decided that this was too long for an installation and forced my laptop to shut down. I think that messed it up. Now I'm stuck in what seems to be 13.04 with bits of 12.10 in it. I tried to upgrade again through software updater but it goes to Partial Upgrade. But when I try that, I get this error message: "An upgrade from 'raring' to 'quantal' is not supported by this tool." Help! What should I do! I'm running my Ubuntu on my Dell Inspiron.

• Virtualbox will run from 32bit installation CD but not 64bit.

  - by MetaDark

  I am trying to set up Windows in Virtual Box, so I don't need to reboot in the rare occasion that I actually need it. The problem is, Virtual Box doesn't preform any errors when I insert the 32bit installation CD but when I try to use the 64bit installation; What!? I am already using the installation disc! I've checked my BIOS to see if I have SVM (AMD's version of VT) disabled and all I see is "Enabled" I have a K9N6PGM2-V2 motherboard A Triple Core AMD Athlon II A Nvdia NForce 430 integrated graphics card 4GB of RAM An 80GB IDE And a 1TB SATA I don't think the last three specifications matter but just in case XP I am pretty sure the CD isn't broken ( I am going to make sure in just a moment ), what could be the cause to this problem? Edit: The 64bit installation CD is not broken, but I found out when trying to install from the 32bit version that it's trying to upgrade, not preform a fresh install - Odd.

• GPL'ing code of a third party?

  - by Mark

  I am facing the following dilemma at the moment. I am using code from a scientific paper in a commercial project. So basically I copied and pasted the code from the paper's pdf into my code editor and use it in my own code. The code in the paper does not have any copy restrictions or license(like the GPL) so I thought I would be ok using it in a commercial project. However, I have seen several gpl licensed open source projects that use the exact same code from the paper to the point of having the same variable names like in the paper. So what happened here is that a gpl license was put on a third parties non gpl'ed code. Are these open source projects in violation of the gpl or would I be in violation of the gpl because I use code which has been gpl'ed? My common sense tells me it is not allowed to gpl somebody elses non-gpl'ed (like in this case from the paper) code but I though I would ask anyway.

• Why are most GNU's software written in C

  - by BallroomProgrammer

  I am a Java developer, and I rarely write GUI program in C. However, I noticed that many GNU's projects, such as PSPP, R, Dia, etc., are written in C, instead of Java or C++. I personally don't mind this, but I am really curious why GNU favors C so much. My understanding is that C is the one that supports the least in object-oriented programming, and today's CS education really emphasizes OOP, as OOP really makes codes more reusable. In this case, why would so many developers choose to develop in C instead of C++ or Java. Does anyone know why GNU's software are so exclusively written in C? Do you think or GNU's software should be written in C++ or Java so that the source code could be more useful to people? Why or why not?

• Mi-Fi LEGO Contest Showcases Ultra Minimal Sci-Fi Designs

  - by Jason Fitzpatrick

  Many LEGO creations showcased by geeks across the web involve thousands upon thousands of bricks to create perfectly scaled recreations of buildings, movie scenes, and more. In this case, the goal is to recreate an iconic Sci-Fi scene with as few bricks as possible. Courtesy of the LEGO enthusiast site The Living Brick, the Microscale Sci-Fi LEGO Contest or Mi-Fi for short, combines Sci-Fi with tiny, tiny, recreations of scenes from shows and movies in the genre. Hit up the group’s Flickr pool for the contest to check out all the great submissions–including a tiny Star Gate, a mini Star Destroyer, and a surprisingly detailed scene from Planet of the Apes.

• How can I get H.264 support?

  - by Chad--24216

  Canonical Limited is shown as a licensee of H.264. I am interested in being able to play H.264 video online when using the Chrome web-browser in Ubuntu (and in the future on Firefox when Firefox supports H.264). Is H.264 support enabled on self-installs of Ubuntu? If not, is there some way I can buy H.264 support for my Ubuntu install? Assume a scenario where I self-installed Ubuntu on a computer that came pre-installed with Windows OS. I'd like to know any and all options available to me for getting H.264 to work on Ubuntu.

• What does "context-free" mean in the term "context-free grammar"?

  - by rick

  Given the amount of material that tries to explain what a context-free grammar (CFG) is, I found it surprising that very few (in my sample, less than 1 in 20) give an explanation on why such grammars are called "context-free". And, to my mind, none succeeds in doing so. My question is, why are context-free grammars called context-free? What is "the context"? I had an intuition that the context could be other language constructs surrounding the currently analyzed construct, but that seems not to be the case. Could anyone provide a precise explanation?

• Request Validation in ASP.NET 4.0

  - by Ben Bastiaensen

  Up to ASP.NET 3.5 Request Validation is enabled by default. In order to to disable this for a page you needed to set the ValidationRequest property in the page directive to false. This is no longer the default case in ASP.NET 4.0. If you want to use this behaviour you need to add the follwing setting in web.config  <httpRuntime requestValidationMode="2.0" /> Of course you need to check all input in the page for XSS or other malicious input if you set the pages request validation to false.

• How to choose the right web development language for my app without much programming experience?

  - by twinbornJoint

  I have my own idea for a web application, and I am not a programmer. The application will work similar to Facebook and Twitter, profiles and feeds. I have learned some computer science theory, all the way up to OOP, but have no practical experience. Without any experience, is there a way I can evaluate the different language and platform choices available to me? What kind of things should I be looking at? Ease of setup? How many followers it has? How can I evaluate whether a language will have the capabilities I need?
