• How to replace GRUB with BURG without overwriting MBR?

  - by StepTNT

  I'd like to install BURG but I don't want it to overwrite my MBR. That's because I've got two bootloaders in my system : Default Windows 7 in MBR Grub in /dev/sda2 With the first power button, it will boot into Windows and with the second button it boots from /dev/sda2, loading Grub and then Kubuntu. Now I want to replace GRUB with BURG. I've installed Burg with burg-install /dev/sda2 --force because I don't want my MBR to be overwritten (pressing the first power button MUST load Windows and avoid showing any sign of Linux). Setup was completed without errors, If I open burg-manager it loads my settings, allowing me to change them and to test everything with burg-emu, so I've changed my settings but the second power button still loads GRUB (Even a different version from the default Kubuntu one). How can I replace GRUB that's on /dev/sda2 with BURG and without overwriting MBR?

• Simple alternating text in Visual Basic 2008

  - by Josh Grate

  I have a simple completed program, but i would like to add one more feature to it but I'm not sure how. I have it set up to send a message automatically every 7 seconds when a text field is selected, repeating the message of course. What I would like for it to do is alternate between two separate messages, instead just repeating the one. I would like the new program to post at an interval of 12 seconds. Can you help me? Here is my coding. Public Class Form1 Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick SendKeys.Send(TextBox1.Text) SendKeys.Send("{ENTER}") End Sub Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Timer1.Enabled = True Timer1.Interval = (TextBox2.Text) End Sub Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click Timer1.Enabled = False End Sub Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Timer1.Enabled = False End Sub End Class

• Question about Partitioning

  - by Trent C

  I am looking to dual boot Windows 7 and Ubuntu 13.10. I have been using windows for work and school for over a year, and have about 100 gig of stored files (backed up of course) and some paid programs. Because of this, I really want my partitioning experience to go well. Unfortunately, I am running into a bit of an anomoly When I load GPart, I see that my sda drive is unallocated http://i.imgur.com/Hi2XhIr.png Whereas my sdb appears to contain all of the windows files and partitions, and make up my C: drive http://i.imgur.com/aaCOXje.png Is this going to be an issue, as all literature on dual boot installation references sda? How do I work around it? System Info: Lenovo IdeaPad Y570- 750GB HDD with 64GB SSD Processor: Intel® Core™ i7-2670QM CPU @ 2.20GHz × 8

• Random MongoDb Syntax: Updates

  - by Liam McLennan

  I have a MongoDb collection called tweets. Each document has a property system_classification. If the value of system_classification is ‘+’ I want to change it to ‘positive’. For a regular relational database the query would be: update tweets set system_classification = 'positive' where system_classification = '+' the MongoDb equivalent is: db.tweets.update({system_classification: '+'}, {$set: {system_classification:'positive'}}, false, true) Parameter Description { system_classification: '+' } the first parameter identifies the documents to select { $set: { system_classification: 'positive' } } the second parameter is an operation ($set) and the parameter to that operation {system_classification: ‘positive’} false the third parameter indicates if this is a regular update or an upsert (true for upsert) true the final parameter indicates if the operation should be applied to all selected documents (or just the first)

• How to Disable or Uninstall Android Bloatware

  - by Chris Hoffman

  Manufacturers and carriers often load Android phones with their own apps. If you don’t use them, they just clutter your system and sometimes in the background, draining resources. Take control of your device and stop the bloatware. We’ll be focusing on disabling – also known as “freezing” bloatware here. It’s a safer process than uninstalling the bloatware completely, and is also easier to accomplish with free apps.

• How can I convert an image from raw data in Android without any munging?

  - by stephelton

  I have raw image data (may be .png, .jpg, ...) and I want it converted in Android without changing its pixel depth (bpp). In particular, when I load a grayscale (8 bpp) image that I want to use as alpha (glTexImage() with GL_ALPHA), it converts it to 16 bpp (presumably 5_6_5). While I do have a plan B (actually, I'm probably on plan 'E' by now, this is really becoming annoying) I would really like to discover an easy way to do this using what is readily available in the API. So far, I'm using BitmapFactory.decodeByteArray(). While I'm at it. I'm doing this from a native environment via JNI (passing the buffer in from C, and a new buffer back to C from Java). Any portable solution in C/C++ would be preferable, but I don't want to introduce anything that might break in future versions of Android, etc.

• How to crawl a webPage with dynamic content added by javascript

  - by blunderboy

  I guess there is a news that Google bots have the capability to understand our javascript code. It means this is possible to fully crawl a webpage which has lazy loading feature enabled. I am using Apache Nutch to crawl websites but I don't think it has the capability to fetch the URLs being injected in HTML page by javascript when the page is scrolled down. I see a lot of websites doing lazy loading for performance issue. So Can somebody please explain me how can i crawl the data which comes in HTML page on lazy load. (On scrolling the page down).

• Are unit tests really used as documentation?

  - by stijn

  I cannot count the number of times I read statements in the vein of 'unit tests are a very important source of documentation of the code under test'. I do not deny they are true. But personally I haven't found myself using them as documentation, ever. For the typical frameworks I use, the method declarations document their behaviour and that's all I need. And I assume the unit tests backup everything stated in that documentation, plus likely some more internal stuff, so on one side it duplicates the ducumentation while on the other it might add some more that is irrelevant. So the question is: when are unit tests used as documentation? When the comments do not cover everything? By developpers extending the source? And what do they expose that can be useful and relevant that the documentation itself cannot expose?

• Unable to install 12.10 on asus r500v

  - by bmdr38

  I have been unable to get beyond the grub boot screen of the live dvd/usb. The Try Ubuntu without installing, Install Ubuntu, etc menu shows, and I have tried adding/replacing nomodeset and no splash with neither helping. Even "Check disc for defects" does not display anything when selected. I am at a complete loss as to how to fix this one. I have had many successful installs in the past, but this is definitely a first for me. Just as FYI, Gfx card: Geforce GT 635M I realize this particular card has Optimus on it, however even the alternative boot/command line install fails to load. Any help would be appreciated. I realize there have been multiple threads on this, but none of the methods within them have solved this yet. Thanks

• Tp_smapi on Thinkpad T440

  - by user2597381

  I have a Thinkpad T440 with Ubuntu 14.04 (using i3wm). I have had trouble installing tp_smapi. I successfully installed it with dpkg -- can't remember whether I used apt or just downloaded it somewhere -- but I can't load the module. When I use modprobe on tp_smapi, I get this: "modprobe: ERROR: could not insert 'tp_smapi': No such device or address" Note that this is different from the error I get when I mistype the module name. I read somewhere that I might have to rebuild my kernel for it to work, but I'd thought that the kernel I was using (3.13.0-24) had that already set up. Has anyone gotten it to work? I hate how Lenovo manages the batteries!

• Wiki based requirements engineering tool

  - by Shanon

  Hi, I'm looking to to build a wiki based tool the helps/aides in the requirements engineering process. More specifically I am hoping to end up with a tool that helps inexperienced users easily create and design requirements documents on a wiki platform. I was wondering if there exist any wiki/wiki platforms that either already exist or are easily extendible or would be worth looking at that for this purpose. For instance some of the features I was hoping to add would be to add structure to a document so that information is filled out in a standardised manner. Another idea I was looking at was to somehow create relationships between different types of documents (for example- a goal diagram gets evolves/ helps in the development of the class diagram). So far I have come across FOSwiki which claims to to fully customisalble...but I'm not sure what it means and what I can really do with that. Any input on FOSwiki is also highly appreciated.

• Printing in booklet fomat

  - by To Do

  In the past I had a printer that had the booklet format option that would print the document two pages at a time ordered in a way that folding the whole printout would produce a booklet which could be stapled in the middle. My current printer does not support this feature. I would like to use some utility or script to convert an A4 pdf to an A5 booklet one. I found this page but I'm getting an error : pdfjam ERROR: can't find pdflatex! How do I get past this issue? Does anybody know of any other solution? I'm on Ubuntu 12.10 AMD64

• What causes the iOS OpenGLES driver to allocate extra memory?

  - by Martin Linklater

  I'm trying to optimize the memory usage of our iOS game and I'm puzzled about when/why the iOS GLES driver allocates extra memory at runtime... When I run our game through Instruments with the OpenGL ES Driver instrument the gartUsedBytes value can fluctuate quite wildly. We preload all our textures and build the buffer objects up front, so it's not the game engine requesting extra memory from GL. Currently we are manually requesting around 50MB of GL memory, yet the gartUsedBytes value sits at around 90MB most of the time, peaking at 125MB from time to time. It seems to be linked to what you are rendering that frame - our PVS only submits VBO's for visible meshes. Can anyone shed some light on what the driver is doing in the background ? Like I said earlier, all our game engine allocations are done on level load, so in theory there shouldn't be any fluctuation on GL memory usage while the level is running. Thanks.

• How to merge multiple internet connections into one

  - by Luis Alvarado

  My PC has 2 wired cards. Both gigalan. It also has 2 wireless cards. One broadcom with proprietary drivers and ralink with open software (which works much better than broadcom). My cellphone can share its connection wirelessly to my PC. But I also have a wired connection. So I have multiple connections that I can use to have internet. How can I merge 2 or more connections together and balance them to enjoy one unified internet experience that it is the sum of all internet connections connected to it. For example if I have an internet connection that offers 1024KB/Sec and another that offers 512KB/Sec and one small one that offers 128KB/Sec, after load balancing and merging all connections, I could download at a speed of 1664KB/Sec using all 3 internet connections as one for example. This question has always intrigued me.

• Funky Behavior NoTracking Query Entities

  I’ve been using a lot of NoTracking queries to grab lists of data that I don’t need change tracked. It enhances performance and cuts down on resources. There are some nuances about these entities, however. One of the interesting behaviors of EF4’s Lazy Loading is that even if you have entities that you have queried with NoTracking on, they will still lazy load related entities.

• Installing Ubuntu on virtualbox with a windows 8 host

  - by ubershmekel

  Installing ubuntu-13.10-desktop-i386.iso gets me to the graphical login screen but after I enter the password I get a black screen. Ctrl-Alt-F2 brings me to a terminal where I can restart lightdm, enter my password again to see another black screen. The screen saver can actually kick into action there and I was told to update packages, but no unity or other ui, just blackenss. The host is windows8-x64 and Virtualbox 4.3.2. I tried installing ubuntu-12.04.3-desktop-i386.iso but that hung during setup. Is there a way to debug? I'm now trying to install Debian to see if that works but wow the network installer takes its sweet time... Update: Debian does work though it gives me a notification that Gnome 3 failed to load. The visual desktop works though so I don't know if there was a substantive problem.

• Do you use to third party companies to review your company's code?

  - by CodeToGlory

  I am looking to get the following - Basic code review to make sure they follow the guidelines imposed. Security code analysis to make sure there are no loopholes. No performance bottlenecks by doing a load test etc. We have lot of code coming in from third parties and is becoming laborious to manage code reviews and hence looking to see if others employ such practices. I understand that it may be a concern for some and would raise the question "Well, who is going to make sure the agency is doing their job right?" But basically I am just looking for a third party who can hold all vendor code to the same standards.

• Manipulating DOM using jQuery

  - by bipinjoshi

  By now you know how to alter existing elements and their attributes. jQuery also allows you insert, append, remove and replace elements from HTML DOM so that you can modify the document structure. For example, say you are calling some WCF service from client script and based on its return values need to generate HTML table on the fly. In this article I am going to demonstrate some of these jQuery features by developing a simple RSS gadget that grabs and displays RSS feed items in a web form.http://www.bipinjoshi.net/articles/90f4fbef-ef36-467b-8ca0-d0922a5902b0.aspx
