  • While installing Ubuntu from Ubuntu Desktop (from USB)

    - by Andres
    I downloaded the Ubuntu Software to create a USB to install Ubuntu. I rebooted my PC (Windows 7), in wich i did a partition (:E) just for Ubuntu. But when i start the installer, it says there's no other OS in my computer, and doesn't give me the option to install it in :E, just the option to format the WHOLE hard drive and install it there. What can i do? Also, i tried Wubi before, but it had an error with "wubildr.mbr"

  • Should CSS be listed on your resume under Languages?

    - by Sandeepan Nath
    I have some doubts like Whether CSS should be put under Languages or not? Although Wikipedia says Cascading Style Sheets (CSS) is a style sheet language ... But do they write CSS under the languages section of the resume, along with PHP, etc? Similarly what about HTML? I have some doubt and I don't want to sound like someone who is not aware of the trends. Just to give an example, currently I have the following languages,frameworks, technologies, etc. listed under the "Technical Expertise" section of my resume - Technical Expertise * Languages - Proficient - PHP 5, Javascript, HTML ?*,CSS ?*,Sass ?*. Beginner - Linux Bash. * Databases - MySQL 5. * Technologies - AJAX. * Frameworks/Libraries - Symfony, jQuery. * CMSes - Wordpress. Although my domain is Web-development/design, I welcome domain-agnostic answers which can provide some generic ideas/reasoning. I have seen, a lot of people messing up these sections (even more serious than my doubts :) ), putting things under wrong sub-headings and thus putting a big question mark on their understanding of those things. I don't know much about XML, Comet Technology etc. Considering those are included too, What things should be put under Languages? E.g. Should CSS be put under Languages? Please give some reasoning to support your views. Where should the others (XML, Comet, cURL etc. ) be put? I welcome some examples of how you put it. Or do you have an additional Keywords section where you write all the unsortables ? Considering a set of standards like W3C standards, etc. do you have a standards sub-heading? I guess I have put the contents of other sections Okay. But do let me know about your ideas and reasoning. After all, I understand there may not be a single answer to this, but let's see what is the trend. Thanks Updates Further, do you mention design patters you have used? Web Services etc.? Where do you mention SOAP, XML etc...

  • Modifying Contiguous Time Periods in a History Table

    Alex Kuznetsov is credited with a clever technique for creating a history table for SQL that is designed to store contiguous time periods and check that these time periods really are contiguous, using nothing but constraints. This is now increasingly useful with the DATE data type in SQL Server. The modification of data in this type of table isn't always entirely intuitive so Alex is on hand to give a brief explanation of how to do it.

  • Application switcher is broken

    - by Byron Hawkins
    After a normal update of my Ubuntu 12.04 install last week, my application switcher has stopped working. I've tried all different settings in CompizConfig, including a variety of shortcut keys and both switcher versions ("Application Switcher" and "Static Application Switcher"). So far there has been no way to get any form of application switcher to appear on my screen. Can anyone give me an idea what might be wrong, or where I might look for more information? Thanks for your help.

  • How do I set up anonymous email forwarder using cPanel?

    - by Gravitas
    Some companies demand your email address, then send you spam. I'm quite familiar with cPanel. How would I set up an anonymous email forwarder, so I can give them a valid email address, and kill that email address if the company turns into an evil spammer? Note that to be effective, it would have to filter out any email addresses listed in the body of the forwarded email (otherwise those email addresses will end up on their spam list too).

  • What is the correlation between the quality of the software development process and the quality of the product?

    - by Ophir Yoktan
    I used to believe the practicing "good" software development methods tends to yield a better product in the long run. However, I've seen quite a few cases where "quick-and-dirty" \ "brute-force" \ "copy-paste" programming appeared to give decent results quicker, and cheaper. This appears especially in cases where time to market is more critical then maintenance overhead. Is there a correlation between the quality of the development process and techniques and the quality of the product?

  • Design pattern for an ASP.NET project using Entity Framework

    - by MPelletier
    I'm building a website in ASP.NET (Web Forms) on top of an engine with business rules (which basically resides in a separate DLL), connected to a database mapped with Entity Framework (in a 3rd, separate project). I designed the Engine first, which has an Entity Framework context, and then went on to work on the website, which presents various reports. I believe I made a terrible design mistake in that the website has its own context (which sounded normal at first). I present this mockup of the engine and a report page's code behind: Engine (in separate DLL): public Engine { DatabaseEntities _engineContext; public Engine() { // Connection string and procedure managed in DB layer _engineContext = DatabaseEntities.Connect(); } public ChangeSomeEntity(SomeEntity someEntity, int newValue) { //Suppose there's some validation too, non trivial stuff SomeEntity.Value = newValue; _engineContext.SaveChanges(); } } And report: public partial class MyReport : Page { Engine _engine; DatabaseEntities _webpageContext; public MyReport() { _engine = new Engine(); _databaseContext = DatabaseEntities.Connect(); } public void ChangeSomeEntityButton_Clicked(object sender, EventArgs e) { SomeEntity someEntity; //Wrong way: //Get the entity from the webpage context someEntity = _webpageContext.SomeEntities.Single(s => s.Id == SomeEntityId); //Send the entity from _webpageContext to the engine _engine.ChangeSomeEntity(someEntity, SomeEntityNewValue); // <- oops, conflict of context //Right(?) way: //Get the entity from the engine context someEntity = _engine.GetSomeEntity(SomeEntityId); //undefined above //Send the entity from the engine's context to the engine _engine.ChangeSomeEntity(someEntity, SomeEntityNewValue); // <- oops, conflict of context } } Because the webpage has its own context, giving the Engine an entity from a different context will cause an error. I happen to know not to do that, to only give the Engine entities from its own context. But this is a very error-prone design. I see the error of my ways now. I just don't know the right path. I'm considering: Creating the connection in the Engine and passing it off to the webpage. Always instantiate an Engine, make its context accessible from a property, sharing it. Possible problems: other conflicts? Slow? Concurrency issues if I want to expand to AJAX? Creating the connection from the webpage and passing it off to the Engine (I believe that's dependency injection?) Only talking through ID's. Creates redundancy, not always practical, sounds archaic. But at the same time, I already recuperate stuff from the page as ID's that I need to fetch anyways. What would be best compromise here for safety, ease-of-use and understanding, stability, and speed?

  • How and when to ask for a pay raise?

    - by Nico
    When should one ask for a pay raise? Will I know when the time is right for a pay raise? or should I just think "I deserve a pay raise for X and Y." When would be a moment to ask for a pay grade? For instance, if you are in a company that outsources to others, could it be the right moment to ask when they move you to a different physical workplace? Maybe a few weeks/months after you started working as a consultant at the client? Should you ask for one after engaging new technologies or something you've never worked with before? In short, should you ask for a raise for a "business motive" (they move you, they assign you new responsibilities), a "professional motive" (you are required to learn new languages or technologies), or a "personal motive" (you are having twins, your mother died and you need to arrange the funeral), or are all of the above potentially valid motives? How should one ask for it? Asking for a pay raise can be difficult for some people, how you deal with this? Do you just walk up to your manager and tell him "I need more money", "I think I deserve a pay raise"? Do you suggest you might have other offers on the table? Couldn't this be counterproductive if you actually really want to stay in the company you are in (because you like the environment, made a few friends, and like all the features they give you besides your pay grade; say: free sodas, parties, after-offices that happen pretty often, a ps3 you can grab when you are tired or want to chill out, courses, english classes, football games, etc, etc. [these would be my reasons not to leave]). I mean, how would you ask for a pay raise, effectively, but without pretending to threaten to leave the company if you don't get it? Because you don't actually want to. How would you deal with their answer? If they tell you they don't think you deserve a raise, would you ask for their reasons, would you get furious and trash the room? If they give you their reasons why they think you don't deserve a pay raise yet, would you discuss this with them or just take their opinion as factual? What if they ask you how much more you think you deserve to be being paid? Should you have thought this before-hand, or expect them to set the new grade? If they do agree to a pay raise, should you expect extra work to be thrown your way, or should everything remain the same, except your pay grade?

  • Take advantage of the stimulus plan by hiring someone!

    - by Randy Walker
    In case you didn’t know, businesses can take advantage of the stimulus package by hiring an unemployed worker.  The Hiring Incentives to Restore Employment (HIRE) Act can pay the business portion of the Social Security taxes as well as give you a $1000 general business tax credit. If you’re unemployed, make sure and mention this to a potential employee! You can find out more information from here on Intuit’s website.  http://www.qbenews.com/QB_Payroll/1003_qbpb/landing_01.html

  • How can I implement 2D cel shading in XNA?

    - by Artii
    So I was just wondering on how to give a scene I am rendering a hand drawn look (like say Crayon Physics). I don't really want to preprocess the sprites and was thinking of using a shader. Cel shading supplies the effect I want to achieve, but I am only aware of the 3D instances for it. So I wanted to ask if anyone knew a way to get this effect in 2D, or if cel shading would work just as fine on 2D scenes?

  • How can I replicate Google Page Speed's lossless image compression as part of my workflow?

    - by Keefer
    I love that Google's Page Speed is able to losslessly compress a lot of my images, but I'd love to make it part of my workflow, prior to uploading a site and making it live. Is there anything I can run locally to give me the same lossless compression? I currently export images from Export For Web from Photoshop, and use a little application called PNGCrusher to reduce file size of PNGs. I'd love to find a faster way though than saving out and replacing the individual images from Page Speed's results.
