• dpkg behaving strangely?

  When I use apt to get a package, I have been receiving the same error message. Here is an example trying to install wicd (which is already installed): Reading package lists...

• Web developer has become uncooperative, what should we do to rescue our site? [closed]

  - by TOM

  What can an individual or a company do if the web designer who has designed their website becomes completely uncooperative? In our case He refuses to meet with us for discussions. He refuses to give us training on the effective use and management of the website he has designed for us (and has been paid in full for) despite this training being part of the original contract. Last year he disappeared for a number of months ,refused to answer emails or phobe calls and was totally unavailable to help us He refuses to give us the details of the hosting of our website. We have totally lost faith in this arrogant and unreasonable guy and would like to break off all relationships with him but ,it appears, he's got us over a barell

• Obtaining a HBITMAP/HICON from D2D Bitmap

  - by Tom

  Is there any way to obtain a HBITMAP or HICON from a ID2D1Bitmap* using Direct2D? I am using the following function to load a bitmap: http://msdn.microsoft.com/en-us/library/windows/desktop/dd756686%28v=vs.85%29.aspx The reason I ask is because I am creating my level editor tool and would like to draw a PNG image on a standard button control. I know that you can do this using GDI+: HBITMAP hBitmap; Gdiplus::Bitmap b(L"a.png"); b.GetHBITMAP(NULL, &hBitmap); SendMessage(GetDlgItem(hDlg, IDC_BUTTON1), BM_SETIMAGE, IMAGE_BITMAP, (LPARAM)hBitmap); Is there any equivalent, simple solution using Direct2D? If possible, I would like to render multiple PNG files (some with transparency) on a single button.

• What do I do if a user uploads child pornography?

  - by Tom Marthenal

  If my website allows uploading images (which are not moderated), what action do I take if a user uploads child pornography? I already make it easy to report images, and have never had this problem before, but am wondering what the appropriate response is. My initial thought is to: Immediately delete (not just make inaccessible) the image File a report with the National Center for Missing and Exploited Children with all information I have on the user (IP, URL, user-agent, etc.), identifying myself as the website operator and providing contact information Check any other images uploaded by that IP user and prevent them from uploading in the future (this is impossible, but I can at least block their account). This seems like a good way to be responsible in reporting, but does this satisfy all of my legal and moral responsibilities? Would it be better not to delete the image and to just make it inaccessible, so that it can be sent to the National Center for Missing & Exploted Children, the police, FBI, etc?

• What naughty ways are there of driving traffic?

  - by Tom Wright

  OK, so this is purely for my intellectual curiosity and I'm not interested in illegal methods (no botnets please). But say, for instance, that some organisation incentivised link sharing in a bid to drive publicity. How could I drive traffic to my link? Obviously I could spam all my friends on social networking sites, which is what they want me to do, but that doesn't sound as fun as trying to game the system. (Not that I necessarily dispute the merit of this particular campaign.) The ideas I've come up with so far (in order of increasing deviousness) include: Link-dropping - This is too close to what they want me to do to be devious, but I've done it here (sorry) and I've done it on Twitter. I'm subverting it slightly by focusing on the game aspects rather than their desired message. AdWords - Not very devious at all, but effectively free with the vouchers I've accrued. That said, I must be pretty poor at choosing keywords, because I've seen very few hits (~5) so far. Browser testing websites - The target has a robots txt which prevents browsershots from processing it, but I got around this by including it in an iframe on a page that I hosted. But my creative juices have run dry I'm afraid. Does anyone have any cheeky/devious/cunning/all-of-the-above idea for driving traffic to my page?

• How do you turn a cube into a sphere?

  - by Tom Dalling

  I'm trying to make a quad sphere based on an article, which shows results like this: I can generate a cube correctly: But when I convert all the points according to this formula (from the page linked above): x = x * sqrtf(1.0 - (y*y/2.0) - (z*z/2.0) + (y*y*z*z/3.0)); y = y * sqrtf(1.0 - (z*z/2.0) - (x*x/2.0) + (z*z*x*x/3.0)); z = z * sqrtf(1.0 - (x*x/2.0) - (y*y/2.0) + (x*x*y*y/3.0)); My sphere looks like this: As you can see, the edges of the cube still poke out too far. The cube ranges from -1 to +1 on all axes, like the article says. Any ideas what is wrong?

• Validating allowed characters or validating disallowed characters

  - by Tom

  I've always validated my user input based on a list of valid/allowed characters, rather than a list of invalid/disallowed characters (or simply no validation). It's just a habit I picked up, probably on this site and I've never really questioned it until now. It makes sense if you wish to, say, validate a phone number, or validate an area code, however recently I've realised I'm also validating input such as Bio Text fields, User Comments, etc. for which the input has no solid syntax. The main advantage has always seemed to be: Validating allowed chars reduces the risk of you missing a potentially malicious character, but increases the risk the of you not allowing a character which the user may want to use. The former is more important. But, providing I am correctly preventing SQL Injection (with prepared statements) and also escaping output, is there any need for this extra barrier of protection? It seems to me as if I am just allowing practically every character on the keyboard, and am forgetting to allow some common characters. Is there an accepted practice for this situation? Or am I missing something obvious? Thanks.

• Advantages of Hudson and Sonar over manual process or homegrown scripts.

  - by Tom G

  My coworker and I recently got into a debate over a proposed plan at our workplace. We've more or less finished transitioning our Java codebase into one managed and built with Maven. Now, I'd like for us to integrate with Hudson and Sonar or something similar. My reasons for this are that it'll provide a 'zero-click' build step to provide testers with new experimental builds, that it will let us deploy applications to a server more easily, that tools such as Sonar will provide us with well-needed metrics on code coverage, Javadoc, package dependencies and the like. He thinks that the overhead of getting up to speed with two new frameworks is unacceptable, and that we should simply double down on documentation and create our own scripts for deployment. Since we plan on some aggressive rewrites to pay down the technical debt previous developers incurred (gratuitous use of Java's Serializable interface as a file storage mechanism that has predictably bit us in the ass) he argues that we can document as we go, and that we'll end up changing a large swath of code in the process anyways. I contend that having accurate metrics that Sonar (or fill in your favorite similar tool) provide gives us a good place to start for any refactoring efforts, not to mention general maintenance -- after all, knowing which classes are the most poorly documented, even if it's just a starting point, is better than seat-of-the-pants guessing. Am I wrong, and trying to introduce more overhead than we really need? Some more background: an alumni of our company is working at a Navy research lab now and suggested these two tools in particular as one they've had great success with using. My coworker and I have also had our share of friendly disagreements before -- he's more of the "CLI for all, compiles Gentoo in his spare time and uses Git" and I'm more of a "Give me an intuitive GUI, plays with XNA and is fine with SVN" type, so there's definitely some element of culture clash here.

• Scalable solution for website polling

  - by Tom Irving

  I'm looking to add push notifications to one of my iOS apps. The app is a client for a website which doesn't offer push notifications. What I've come up with so far: App sends a message to home server when transitioning to background, asking the server to start polling the website for the logged in user. The home server starts a new process to poll for that user. Polling happens every so many seconds / minutes. When the user returns to the iOS app, the app sends a message to the home server to stop polling. The home server kills the process polling for the user. Repeat. The problem is that this soon becomes stupid: 100s of users means 100s of different processes. It's just not scalable in the slighest. What I've written so far is in PHP, using CURL to do the polling and I started with PHP a few days ago, so maybe I'm missing something obvious that could help me with this. Some advice would be great.

• Moving my sprite in XNA using classes

  - by Tom

  Hey, im a newbie at this programming lark and its really frustrating me. I'm trying to move a snake in all directions while using classes. Ive created a vector2 for speed and ive attempted creating a method which moves the snake within the snake class. Now I'm confused and not sure what to do next. Appreciate any help. Thanks :D This is what i've done in terms of the method... public Vector2 direction() { Vector2 inputDirection = Vector2.Zero; if (Keyboard.GetState().IsKeyDown(Keys.Left)) inputDirection.X -= -1; if (Keyboard.GetState().IsKeyDown(Keys.Right)) inputDirection.X += 1; if (Keyboard.GetState().IsKeyDown(Keys.Up)) inputDirection.Y -= -1; if (Keyboard.GetState().IsKeyDown(Keys.Down)) inputDirection.Y += 1; return inputDirection * snakeSpeed; } Appreciate any help. Thanks :D EDIT: Well let me make everything clear. Im making a small basic game for an assignment. The game is similar to the old snake game on the old Nokia phones. I've created a snake class (even though I'm not sure whether this is needed because im only going to be having one moving sprite within the game). After I written the code above (in the snake class), the game ran with no errors but I couldn't actually move the image :( EDIT2: Thanks so much for everyones responses!!

• what is message passing in OO?

  - by Tom

  I've been studying OO programming, primarily in C++, C# and Java. I thought I had a good grasp on it with my understanding of encapsulation, inheritance and polymorphism (as well as reading a lot of questions on this site). One thing that seems to popup up here and there is the concept of "message passing". Apparently, this is something that is not used whilst OO programming in today's mainstream languages, but is supported by Smalltalk. My questions are: What is message passing? (Can someone give a practical example?) Is there any support for this "message passing" in C++, C# or Java?

• Why do my Google sitelinks show gibberish for a PDF link?

  - by Tom

  I have a website which Google lists nicely along with site links. One of the site links - to a PDF file - shows un-human gibberish e.g 67,8;45:: 56 83 @7<1. (7/0;,*;: /59( (7/0;,;<7, <7)(60:4 (9<7 /+ +2, VU I thought it might be due to the PDF's title property so I changed it. But there hasn't been an improvement to the site link. Other PDF site links are fine and display the title property as desired. Does anyone know how I might rectify this problem or what might be the cause? My uninformed guess is it's some transliteration problem between code and display text which, I suppose, means I ought to recondition the PDF file in some way. Not sure how.

• Drawing shapes dynamically on an image through web browser

  - by Tom Beech

  We have a scenario where we create floor plans of locations when we visit. The floor plan is finally shown on the web. It's come to the point now where we want to show floor plans but have a key with various items on them, when an item on the key is clicked, the image should highlight all the areas of the floorplan that have that specific item. I guess we're looking for some sort of open standard javascript lib to deal with SVG (has to work pre IE9 so pure SVG wont cut it) and the floor plans have to be able to be created through a .net application to be deployed on the web. I'd rather stay away from flash if at all possible to be honest. Below are a few conceptual images of what we're trying to achieve.

• Removing date from Google SERP

  - by Tom Gullen

  We are going through our site analysing the SEO. I find that sometimes on a google results page, some results show a date, others don't. Example (from same query): I prefer the result not to have the date in it, as 20 Oct 2009 probably has an adverse effect on the clickability of the result. Is this Google putting it in? Or the page itself? Or a combination of both (IE, if over a certain age, it includes date). The two URLs are: http://www.scirra.com/forum/perlin-noise-plugin_topic38498.html http://www.scirra.com/forum/dungeon-maze-generator_topic40611.html Any way to remove the dates? I'm thinking, if the age of the thread is 4 months don't display the date on the page, then Google might not find a date reference for it?

• How different is WPF from ASP.NET [closed]

  - by Tom

  I have been quickly moved over to a different project at work because the project needs more help. I was chosen because they are confident in my abilities and they thought I would be best fit for the next couple weeks to help finish the application out. I am a little nervous. I do tend to pick things up quickly. I was moved to a different project at the beginning of this year and now I know it like the back of my hand. Previously I was on another project. Both of these projects were an ASP.NET web application, which I believe is considered a winforms web application? The project I am moving to is a desktop WPF application. I have read that many people enjoy developing their applications with WPF. I just have never dealt/worked with WPF before. I like to consider myself pretty good at ASP.NET/C# and I do a solid job. We deal with a lot of data processing from the database and report generation. So I do get to experience C# more so than some web applications where the C# end of it is mostly just event driven and simple instructions. How different are the two? Will it be completely foreign to me? Or is it just a different way of looking at a problem and I can familiarize myself quickly? Thanks for the input.

• Why is my Ubuntu 10.10 CD not booting?

  - by Tom Brito

  I have downloaded Ubuntu 10.10 and burned the ISO but it will not boot. I discarded problems with the ISO, as I've downloaded from the official website with no errors, and burned it with no errors. I discarded problems with the burning, as looks like it was recorded with no errors here and later in another computer. I discarded problems with my DVD reader as other cds boots fine. I'm currently using Ubuntu 9.10, I know I can upgrade via internet, but I have this same problem with my Windows XP cd, so I really would like to discover what's going on here.. My Ubuntu 9.10 cd boots just right, but the new one not. What else can be? Or what more precise tests can I make to discover where's the problem? --More info What happens when I try to boot with the Ubuntu 10.10 cd is that it behavior like there's no bootable cd in the drive. It just don't find the boot on the cd, and start the HD system. My notebook is an Amazon PC Intel Celeron 1.5 with 2Gb memory, a DVD-RW driver, HD samsung with 260GB.

• What features does D3D have that OpenGL does not (and vice versa)?

  - by Tom

  Are there any feature comparisons on Direct3D 11 and the newest OpenGL versions? Well, simply put, Direct3D 11 introduced three main features (taken from Wikipedia): Tesselation Multithreaded rendering Compute shaders Increased texture cache Now I'm wondering, how does the newest versions of OpenGL cope with these features? And since I have this feeling that there are features that Direct3D lacks from OpenGL's side, what are those?
