  • When to drop an IT job

    - by Nippysaurus
    In my career I have had two programming jobs. Both these jobs were in a field that I am most familiar with (C# / MSSQL) but I have quit both jobs for the same reason: unmanageable code and bad (loose) company structure. There was something in common with both these jobs: small companies (in one I was the only developer). Currently I am in the following position: being given written instructions which are almost impossible to follow (somewhat of a fools errand). we are given short time constraints, but seldom asked how long work will take, and when we do it is always too long and needs to be shorter (and when it ends up taking longer than they need it to take, it's always our fault). there is no time for proper documenting, but we get blamed for not documenting (see previous point). Management is constantly screwing me around, saying I'm underperforming on a given task (which is not true, and switching me to a task which is much more confusing). So I must ask my fellow developers: how bad does a job need to be before you would consider jumping ship? And what to look out for when considering taking a job. In future I will be asking about documented procedures, release control, bug management and adoption of new technologies. EDIT: Let me add some more fuel to the fire ... I have been in my current job for just over a year, and the work I am doing almost never uses any of the knowledge I have gained from the other work I have been doing here. Everything is a giant learning curve. Because of this about 30% of my time is learning what is going on with this new product (who's owner / original developer has left the company), 30% trying to find the relevant documentation that helps the whole thing make sense, 30% actually finding where to make the change, 10% actually making the change.

  • Execute javascript in PHP

    - by Andreas Bonini
    I'm generating your typical Web 2.0 HTML page with PHP: it contains a lot of <script> tags and javascript code that will substantially change the DOM after the load event. Is there a way to get the final HTML code directly from PHP, without opening the page with any browser? For example, let's say the HTML for the page is (it's just an example): <html> <head> <script>...the jquery library code...</script> <script>$(document).ready(function() { $("body").append("<p>Hi!</p>");</script> </head> <body> </body> </html> This HTML is saved in the $html PHP variable. Now, I want to pass that variable to some function that will return $result = <html>....<body><p>Hi!</p></body></html>. Is this possible?

  • Is OpenGL required for my iPhone game?

    - by Ben X Tan
    On an iPhone: If I am writing a game that has multiple levels, with multiple animations (image sequences), jpg and png (transparent), some full screen and some not, some looped and some played once only. What is the best way of doing it? Each level might have up to 10MB of images. Add on to this music, and video (cut scenes). All 2D graphics, no 3D models. Is OpenGL required? Or can this be achieved with Quartz or Core Animation?

  • Wrong image dimensions when it's dynamically loaded on a page the 1st time

    - by Nikita Barsukov
    I have the following piece of Javascript code on my web-page var central_image = document.createElement("img") central_image.setAttribute("src", imgs[curr_image_no - 1]); central_image.setAttribute("name", "jpeg"); document.getElementById("photo").appendChild(central_image); central_image.onload = getDimensions(); //function that alerts image dimensions Now, when the central_image is loaded for the 1st time in Firefox, its height always equals to 0. In IE its dimensions are 28 x 30 pixels. When I reload image, its dimensions are OK in both browsers. I guess the problem is that function getDimensions() starts before image was loaded completely. How to change that?

  • How to build unlimited level of menu through PHP and mysql

    - by Starx
    Well, to build my menu my menu I use a db similar structure like this To assign another submenu for existing submenu I simply assign its parent's id as its value of parent field. parent 0 means top menu now there is not problem while creating submenu inside another submenu now this is way I fetch the submenu for the top menu <ul class="topmenu"> <? $list = $obj -> childmenu($parentid); //this list contains the array of submenu under $parendid foreach($list as $menu) { extract($menu); echo '<li><a href="#">'.$name.'</a></li>'; } ?> </ul> What I want to do is. I want to check if a new menu has other child menu and I want to keep on checking until it searches every child menu that is available and I want to display its child menu inside its particular list item like this Home ........

  • [C#][XNA] Draw() 20,000 32 by 32 Textures or 1 Large Texture 20,000 Times

    - by Rudi
    The title may be confusing - sorry about that, it's a poor summary. Here's my dilemma. I'm programming in C# using the .NET Framework 4, and aiming to make a tile-based game with XNA. I have one large texture (256 pixels by 4096 pixels). Remember this is a tile-based game, so this texture is so massive only because it contains many tiles, which are each 32 pixels by 32 pixels. I think the experts will definitely know what a tile-based game is like. The orientation is orthogonal (like a chess board), not isometric. In the Game.Draw() method, I have two choices, one of which will be incredibly more efficient than the other. Choice/Method #1: Semi-Pseudocode: public void Draw() { // map tiles are drawn left-to-right, top-to-bottom for (int x = 0; x < mapWidth; x++) { for (int y = 0; y < mapHeight; y++) { SpriteBatch.Draw( MyLargeTexture, // One large 256 x 4096 texture new Rectangle(x, y, 32, 32), // Destination rectangle - ignore this, its ok new Rectangle(x, y, 32, 32), // Notice the source rectangle 'cuts out' 32 by 32 squares from the texture corresponding to the loop Color.White); // No tint - ignore this, its ok } } } Caption: So, effectively, the first method is referencing one large texture many many times, each time using a small rectangle of this large texture to draw the appropriate tile image. Choice/Method #2: Semi-Pseudocode: public void Draw() { // map tiles are drawn left-to-right, top-to-bottom for (int x = 0; x < mapWidth; x++) { for (int y = 0; y < mapHeight; y++) { Texture2D tileTexture = map.GetTileTexture(x, y); // Getting a small 32 by 32 texture (different each iteration of the loop) SpriteBatch.Draw( tileTexture, new Rectangle(x, y, 32, 32), // Destination rectangle - ignore this, its ok new Rectangle(0, 0, tileTexture.Width, tileTexture.Height), // Notice the source rectangle uses the entire texture, because the entire texture IS 32 by 32 Color.White); // No tint - ignore this, its ok } } } Caption: So, effectively, the second method is drawing many small textures many times. The Question: Which method and why? Personally, I would think it would be incredibly more efficient to use the first method. If you think about what that means for the tile array in a map (think of a large map with 2000 by 2000 tiles, let's say), each Tile object would only have to contain 2 integers, for the X and Y positions of the source rectangle in the one large texture - 8 bytes. If you use method #2, however, each Tile object in the tile array of the map would have to store a 32by32 Texture - an image - which has to allocate memory for the R G B A pixels 32 by 32 times - is that 4096 bytes per tile then? So, which method and why? First priority is speed, then memory-load, then efficiency or whatever you experts believe.

  • Text misaligns in IE

    - by kingrichard2005
    I have a ASP.net web page I'm working with, I didn't create it myself, with the following HTML code: <DIV style="POSITION: absolute; TEXT-ALIGN: center; WIDTH: 1400px; TOP: 60px; LEFT: 125px"> <SPAN style="TEXT-ALIGN: center; FONT-SIZE: xx-large" id=labelInstructions>Some Text: <BR><BR></SPAN> <TABLE style="WIDTH: 1200px" border=1 align=center> <TBODY> <TR> <TD><LABEL style="FONT-SIZE: x-large" for=FileUpload1>ENTER Path: </LABEL><INPUT id=FileUpload1 size=70 type=file name=FileUpload1></TD> </TR> <TR> <TD><SPAN style="COLOR: red; FONT-SIZE: medium" id=fileUploadError><BR><BR></SPAN></TD> </TR> <TR> <TD> <TABLE style="WIDTH: 1200px" border=1> <TBODY> <TR> <TD style="WIDTH: 400px; FONT-SIZE: x-large" vAlign=top align=right>FILE CONTENT INSTRUCTIONS:</TD> <TD style="WIDTH: 850px; FONT-SIZE: x-large" vAlign=top align=left>INSTRUCTION 1<BR>INSTRUCTION 2<BR></TD></TR> <TR><TD></TD></TR> <TR> <TD style="WIDTH: 400px; FONT-SIZE: x-large" vAlign=top align=right>FILE CONTENT EXAMPLE:</TD> <TD style="WIDTH: 850px; FONT-SIZE: x-large" vAlign=top align=left>EXAMPLE 1<BR>EXAMPLE 2<BR><BR></TD> </TR> </TBODY> </TABLE> </TD> </TR> </TBODY> </TABLE> </DIV> When this html is displayed in IE, I notice that the alignment of the text in the cells in the inner table, i.e. the table that is in the third cell of the outer table, is distorted when zooming in and out on it. I have a fixed table setting in pixels instead of percentages, so I don't understand why this is an issue. I want the text in the cells to stay in the same position when zooming. The code must be manipulated from the code behind, so I cannot create a separate CSS file. Any help is appreciated. Here are two examples to illustrate what I'm talking about: Normal zoom at 100%: Zoom at 75%: Notice in the second image the two table cells at the bottom are slightly offset to the left. UPDATE: Yes, I understand, we will be implementing a new system in the near future. Obviously this is old and very non-standard, this was dropped in my lap when I started working with it. And we're coming up with plans for a new system to replace it, in the meantime, this is what I have to deal with.

  • Connect 4 with neural network: evaluation of draft + further steps

    - by user89818
    I would like to build a Connect 4 engine which works using an artificial neural network - just because I'm fascinated by ANNs. I'be created the following draft of the ANN structure. Would it work? And are these connections right (even the cross ones)? Could you help me to draft up an UML class diagram for this ANN? I want to give the board representation to the ANN as its input. And the output should be the move to chose. The learning should later be done using backpropagation and the sigmoid function should be applied. The engine will play against human players. And depending on the result of the game, the weights should be adjusted then.

  • How do you prove a function works?

    - by glenn I.
    I've recently gotten the testing religion and have started primarily with unit testing. I code unit tests which illustrate that a function works under certain cases, specifically using the exact inputs I'm using. I may do a number of unit tests to exercise the function. Still, I haven't actually proved anything other than the function does what I expect it to do under the scenarios I've tested. There may be other inputs and scenarios I haven't thought of and thinking of edge cases is expensive, particularly on the margins. This is all not very satisfying to do me. When I start to think of having to come up with tests to satisfy branch and path coverage and then integration testing, the prospective permutations can become a little maddening. So, my question is, how can one prove (in the same vein of proving a theorem in mathematics) that a function works (and, in a perfect world, compose these 'proofs' into a proof that a system works)? Is there a certain area of testing that covers an approach where you seek to prove a system works by proving that all of its functions work? Does anybody outside of academia bother with an approach like this? Are there tools and techniques to help? I realize that my use of the word 'work' is not precise. I guess I mean that a function works when it does what some spec (written or implied) states that it should do and does nothing other than that. Note, I'm not a mathematician, just a programmer.

  • Why function callback of Connection is not handled with Yahoo UI ?

    - by quilovnic
    I use Yahoo UI with Grails (so grailsui) and I try to upload a file with Ajax and get a JSON response from the server : The response is correctly returned by my controller but a popup is displayed to save the file but it's not a file it's a JSON result. My Yahoo Code is : callback = { success: function(o){alert('success');}, failure: function(o){alert('failure');} } YAHOO.util.Connect.asyncRequest('POST', '/my/url', callback); The http response is the JSON result. What's hell is wrong ? Why does I have dialog box to download the file ? Thanks a lot.
