• SQL Concatenate

  - by Bunch

  Concatenating output from a SELECT statement is a pretty basic thing to do in SQL. The main ways to perform this would be to use either the CONCAT() function, the || operator or the + operator. It really all depends on which version of SQL you are using. The following examples use T-SQL (MS SQL Server 2005) so it uses the + operator but other SQL versions have similar syntax. If you wanted to join two fields together for a full name: SELECT (lname + ', ' + fname) AS Name FROM tblCustomers To add some static text to a value: SELECT (lname + ' - SS') AS Name FROM tblPlayers WHERE PlayerPosition = 6 Or to select some text and an integer together: SELECT (lname + cast(playerNumber as varchar) AS Name FORM tblPlayers Technorati Tags: SQL

• Any way to list similar commands?

  - by Septagram

  When you write the command name wrong, bash often does this: septi@norbert:~$ good No command 'good' found, did you mean: Command 'gold' from package 'binutils' (main) Command 'gmod' from package 'gmod' (universe) Command 'goo' from package 'goo' (universe) Command 'god' from package 'god' (universe) Command 'geod' from package 'proj-bin' (universe) Command 'gord' from package 'scotch' (universe) good: command not found Or sometimes it does this: septi@norbert:~$ nftp No command 'nftp' found, but there are 23 similar ones nftp: command not found Is there any way to ask bash to show these 23 similar commands for me? And, is there a way to show similar commands, including those that aren't yet installed, instead of running the application, ftp for example?

• Finding a good University [closed]

  - by Liamh101

  I've currently been searching for good Universities to study Software Engineering or Computer Science at. The three Universities I've chosen so far are: Brighton University (This is my main pick so far) Plymouth Uni Manchester Metropolitan I would just like to know from people who have actually studied at these places to see if there all that there cracked up to be and I'm not going to be wasting up to four years of my life with a course that isn't very well taught. Would love to hear from people and if there are any Universities in the UK that you are/have studied at and are finding really good for learning Programming that would be nice too. Thanks!

• How to make Ubuntu LiveCD be able to use USB Flash drive and external hard drive?

  - by ????

  I am booting up Ubuntu 2012.04 LiveCD... and was able to do /sudo mount /dev/sda1 /mnt and be able to see files in /mnt, which is the main hard drive that can't boot up any more. So to copy files from /mnt to an external hard drive or USB flash drive, I connected a 1TB external hard drive and 2 USB flash drives to the computer, but for some reason, in "File Systems", I can't drag and drop files from /mnt into those external hard drive or USB flash drives? I can't open or look into those drives either... How to make it work?

• C# XNA Make rendered screen a texture2d

  - by redcodefinal

  I am working on a cool little city generator which makes cities in the isometric perspective. However, a problem arose where if the grid size was over a certain limit it would have awful lag. I found the main problem to be in the draw method. So I took the precautionary step of rendering only items that were onscreen. This fixed the lag but, not by much. The idea I have is to render the frame once and take a snapshot. Then, display that as a texture2d on screen. This way I don't have to render 1,000,000 objects every frame since they don't change anyways. TL;DR - I want to Take a snapshot of an already rendered frame Turn it into a Texture2D Render that to the screen instead of all the objects. Any help appreciated.

• Can desktop applications be written using javascript?

  - by jase21

  Is it currently possible to write desktop applications using javascript, html, css? Possible solutions: Use Adobe AIR runtime and program in js. But no, if I'm using AIR, the AS3 suites it the most. So not a good option. GWT: No because it uses Java and then convert it to js or what ever. Pyjamas: Interesting. But I'm currently focusing on JavaScript. So I don't want to use python and cross-compile to js. Run a local server and use the browser in full screen mode. Sort of okay, but still its the same browser thing. And difficult to distribute. So what is the best option? I'm excited about node.js which is the main reason for looking into JavaScript. Otherwise I would have choose python.

• Setting a leader from a sprite array

  - by Craig

  I'm looking to set a leader from an array of sprites, I keep on getting a NullReferenceException was unhandled error from within my main game class when calling the UpdateMouse Method. What have I dont wrong here? class MouseSprite { Random random = new Random(); private MouseSprite leader; public void UpdateBoundaryBox() { mouseBounds.X = (int)mousePosition.X - mouseTexture.Width / 2; mouseBounds.Y = (int)mousePosition.Y - mouseTexture.Height / 2; } public void UpdateMouse(Vector2 position, MouseSprite [] mice, int numberMice, int index) { Vector2 catPosition = position; int enemies = numberMice; this.alive = true; mice[random.Next(0, mice.Length)] = leader;

• Texture not drawing on cubes

  - by Christian Frantz

  I can draw the cubes fine but they are just solid black besides the occasional lighting that goes on. The basic effect is being set for each cube also. public void Draw(BasicEffect effect) { foreach (EffectPass pass in effect.CurrentTechnique.Passes) { pass.Apply(); device.SetVertexBuffer(vertexBuffer); device.Indices = indexBuffer; device.DrawIndexedPrimitives(PrimitiveType.TriangleList, 0, 0, 8, 0, 12); } } The cubes draw method. TextureEnabled is set to true in my main draw method. My texture is also loading fine. public Cube(GraphicsDevice graphicsDevice, Vector3 Position, Texture2D Texture) { device = graphicsDevice; texture = Texture; cubePosition = Position; effect = new BasicEffect(device); } The constructor seems fine too. Could this be caused by the Vector2's of my VertexPositionNormalTexture? Even if they were out of order something should still be drawn other than a black cube

• How access PhysicalMaterial from Actor Class?

  - by EmAdpres

  I use Projectile for my weapon system and UDKProjectile has two main function to handle Hit of projectiles(=bullet of my weapon): simulated function ProcessTouch(Actor Other, Vector HitLocation, Vector HitNormal) // For Actors simulated event HitWall(vector HitNormal, actor Wall, PrimitiveComponent WallComp) // Everything except Actors ( I guess) the first method, the function just give me the actor which I hit and my question is How I can get that actor's physical material by first parameter ( Other ), in order to make a proper react about it ( for example a proper Sound of collide ) ... A tricky (but hateful ) way which I knew works is, make a Trace from a little back of that actor to that actor, and use HitInfo parameter which include physical Material ! But there should be a more standard way !

• Site Description h2 vs p

  - by user1010609

  I tend to follow this html structure while creating new site on my main page: <div class="header"> <img alt="keyword" title="keyword logo" src="keyword.png" /> <div> <h1>keyword</h1> <p><b>keyword + hierarchy keywords</b></p> </div> </div> As you can see Im using <p><b></b></p> to put short description of the site in it but I was wondering If maybe h2 would be better to use here?

• In Joomla how to change the module mod_news_show_gk3???

  - by Emerson

  How can I change the mod_news_show_gk3 module to: Change the size of the post image. It uses the first image of the post, but it seems to not be resizing the image. Add an extra field: It is important to show in the main page what is the source of the post. I would then like to add an extra field during post editing time, namely "source", and then I would like to show the source below the title and before the text. Change the title size. Title is oversized and I couldn't find any way to decrease its size. Add a border around the section. Here is the address: http://central.antinovaordemmundial.com/ Thanks!

• bump mapping with 2 normal maps

  - by DorkMonstuh

  I was wondering if its actually possible to do bump mapping with 2 normal maps... I have tried doing it this way however I get a function overload on max and dot. uniform sampler2D n_mapTex; uniform sampler2D n_mapTex2; uniform sampler2D refTex; varying mediump vec2 TexCoord; varying mediump float vTime; void main() { mediump vec4 wave = texture2D(n_mapTex, TexCoord - vTime); mediump vec4 wave2 = texture2D(n_mapTex2, TexCoord + vTime); mediump vec4 bump = mix(wave2, wave, 0.5); //this extracts the normals from the combined normal maps mediump vec4 normal = normalize(bump.xyzw * 2.0 - 1.0); //determines light position mediump vec3 lightPos = normalize(vec3(0.0, 1.0, 3.0)); mediump float diffuse = max(dot(normal, lightPos),0.0); gl_FragColor = mix(texture2D(refTex, TexCoord), bump, 0.5); }

• How to make content display on their proper pages on search engines

  - by Dendory

  So my site has a blog and gallery, both working the same way. There's an index, and each post has a permalink going to the individual entry. However, if I search for some of the content on Google, often it returns a link to the index, just because it happened to have been on the first page when it was crawled, instead of the individual post pages. This is especially true in cases of images. How can I make it so that Google returns the proper pages for the posts instead of just the main page of my site? My whole site is custom php code I made.

• What to choose for beginner: PHP/Python/Ruby

  - by Nai

  I'm a beginner teaching myself to code but I would like he insight of the PSE community and helping choose where to start. My main objective is to be able to create a basic website to first test my business idea and from there iterate on it quickly to minimise my learning time. The most important criteria for me is speed. An example of speed would be pre-built components available open source and not having to write one from scratch. From my research, this seems to be a death match between the following languages and frameworks: PHP and CakePHP Python and Django Ruby and Rails Assumptions: I am going to be equally good (or bad) in all 3. It is going to be equally easy to find competent developers in either language. I know this to be false already by lets assume that it is. This question is not meant to karma whore as I've seen how passionate some of these standoff questions have been and I'll be happy to turn it into a community wiki.

• Is it bad form to stage a function's steps in intermediate variables (let bindings)?

  - by octopusgrabbus

  I find I tend to need intermediate variables. In Clojure that's in the form of let bindings, like cmp-result-1 and cmp-result-2 in the following function. (defn str-cmp "Takes two strings and compares them. Returns the string if a match; and nil if not." [str-1 str-2 start-pos substr-len] (let [cmp-result-1 (subs str-1 start-pos substr-len) cmp-result-2 (subs str-2 start-pos substr-len)] (compare cmp-result-1 cmp-result-2))) I could re-write this function without them, but to me, the function's purpose looks clearer. I tend to do this quite in a bit in my main, and that is primarily for debugging purposes, so I can pass a variable to print out intermediate output. Is this bad form, and, if so, why? Thanks.

• Programming language specific package management systems

  - by m0nhawk

  There are some programming languages for which exist their own package management systems: CTAN for TeX CPAN for Perl Pip & Eggs for Python Maven for Java cabal for Haskell Gems for Ruby Is there any other languages with such systems? What about C and C++? (that's the main question!) Why there are no such systems for them? And isn't creating packages for yum, apt-get or other general package management systems better? UPD: And what about unification? Have someone tried to unify that "the zoo"? If yes, looks like that project didn't succeed.

• Terra lang and Lua

  - by msalese

  I was reading on terralang site about terra language as "a new low-level system programming language that is designed to interoperate seamlessly with the Lua programming language..." Zach DeVito (the main author) write about the use of terra : A scripting-language with high-performance extensions..... An embedded JIT-compiler for building languages..... A stand-alone low-level language.... But (may be my fault) I don't understand if terra is: a luaJit competitor a better system to interface with c library something better than luaJit using llvm Can someone help me to better understand what is going on terralang project ? Thanks

• How to make LBP-1120 Canon printer work?

  - by cipricus

  Initially this question was limited to 11.10. Now I am in (Lubuntu) 12.10. (On the changes in the question see this meta question). Considering 11.10 I have tried different (or not so different) approaches - that also other users commented here. My main references were: the ubuntu official documentation website on the LBP Canon driver package, this Unixmen solution which partly refers to Radu Cotescu script that aims at providing a near-automated install, and an updated by Unixmen version of that very script (download here). None worked for me.

• What's the difference between the code inside a finally clause and the code located after catch clause?

  - by facebook-100005613813158

  My java code is just like below: public void check()throws MissingParamException{ ...... } public static void main(){ PrintWriter out = response.getWriter(); try { check(); } catch (MissingParamException e) { // TODO Auto-generated catch block out.println("message:"+e.getMessage()); e.printStackTrace(); out.close(); }finally{ out.close(); } //out.close(); } Then, my confusion is: what the difference if I put out.close() in a finally code block or if I just remove finally code block and put out.close() behind catch clause (which has been commented in the code). I know that in both ways, the out.close() will be executed because I know that whether the exception happened, the code behind the catch clause will always be executed.

• Secure Open Source?

  - by opatachibueze

  I want to make a delicate application of mine (an antivirus actually) open source but I want to have a control on who really obtains the source or not. Preferably they should apply and I or administrators approve their applications. Is there any online platform for this? The main reason for the control/security is to possibly prevent malware makers to easily discover how to bypass the stealth checking methods it utilizes for malware detection. Edit: I am looking for advice - possibly to hear from someone who has done something similar. Thanks!

• How to proxy with apache site from same domain but another port as a subfolder?

  - by myWallJSON

  So I have a problem - I have my main site on apache web server on debian on port 80; I develop a web server (in some C++ or C#) and it currently runs on port 6666. But some people are living under firewalls and can access only port 80. I wonder if it is possible via apache map all requests to say mysite.com:80/6666/url as if they were to mysite.com:6666/url, not map via redirection, but really make apache stream content from my site to user as if it were in some folder?

• Tunnels in pseudo 3D racing game

  - by Nicholas

  How would one go about doing tunnels in a pseudo 3D racing game ? The main problem I have at the moment is perspective - I cant think of a way, beyond having to Z sort the sprites and tunnel coordinates, so that vehicles are displayed in front of the tunnel entrance and somehow block the display when out of site. I would like my tunnels to be used on both flat, curved and hills and slopes. The tunnel enterance/exit is made up of 3 separate graphics, (left, right and top), whilst inside the tunnel it is just one line graphic along the top (the idea being its supposed to be a set distance above the current vertical road position). As you can see from the picture, the vehicles are still being rendered whilst in the tunnel. I've converted the Code Incomplete road system to GLBasic.

• blurry images with mogrify & convert

  - by user140393

  Does anyone know why this image is so blurry? I did a convert from pdf to png and it turned out like that. Before deleting imagemagick and it's entire toolset from software-center most of my image programs were displaying like this image. Now for the most part it's just blurry, though a couple still display like that such as gimp. I am running in xfce maybe it's to do with the distribution enviornment. Main issue is the absurd blurriness. I reinstalled all additional packages that were available for imagemagick in the software-center I use convert *.pdf *.png & mogrify -format png *.pdf to convert Now on the other hand if I converted the file to djvu and converted that to a tif. The images have no problem converting. More so it does not generate an oversized tif file of around 25mb compared to 3mb with djvu which is super clear & no blurriness.
