  • What do you do when your naming convention clashes with your language?

    - by Jon Purdy
    Okay, this is one of those little things that always bugged me. I typically don't abbreviate identifiers, and the only time I use a short identifier (e.g., i) is for a tight loop. So it irritates me when I'm working in C++ and I have a variable that needs to be named operator or class and I have to work around it or use an abbreviation, because it ends up sticking out. Caveat: this may happen to me disproportionately often because I work a lot in programming language design, where domain objects may mirror concepts in the host language and inadvertently cause clashes. How would you deal with this? Abbreviate? (op) Misspell? (klass) Something else? (operator_)

  • Implementing a ILogger interface to log data

    - by Jon
    I have a need to write data to file in one of my classes. Obviously I will pass an interface into my class to decouple it. I was thinking this interface will be used for testing and also in other projects. This is my interface: //This could be used by filesystem, webservice public interface ILogger { List<string> PreviousLogRecords {get;set;} void Log(string Data); } public interface IFileLogger : ILogger { string FilePath; bool ValidFileName; } public class MyClassUnderTest { public MyClassUnderTest(IFileLogger logger) {....} } [Test] public void TestLogger() { var mock = new Mock<IFileLogger>(); mock.Setup(x => x.Log(Is.Any<string>).AddsDataToList()); //Is this possible?? var myClass = new MyClassUnderTest(mock.Object); myClass.DoSomethingThatWillSplitThisAndLog3Times("1,2,3"); Assert.AreEqual(3,mock.PreviousLogRecords.Count); } This won't work I don't believe as nothing is storing the items so is this possible using Moq and also what do you think of the design of the interface?

  • Fan very loud in Ubuntu 12.10

    - by Jon
    I recently installed 12.10 on my Desktop PC, moving away from Windows 7. For some reason, the fan in my computer is making an enormous amount of noise (it is running at full speed constantly). Under Windows 7, the fan would slow itself down and run at an acceptable noise level. Now, it is nearly unbearable. Checked the processes, and none are taking up a huge load on the CPU. Please help as I really can't endure this noise, and I do not want to go back to Windows 7 on this box. Some specs: - Intel 2.26 duo core - ATI 4870 - 4GB - 650W power supply

  • IE8 HTTPs Download Issue

    - by Jon Egerton
    I have a problem with a system I develop related to IE8 downloading over SSL (ie on sites using https://...) and is described on this MS kb article: http://support.microsoft.com/kb/323308 We use the HTTPCacheability.NoCache option as the data being downloaded is sensitive, and is downloaded from a secured site. I don't want that data to be cached on any of the proxies etc that the response passes through back to the client. The article describing the issue details a fix to the client side registry changing a BypassSSLNoCacheCheck setting. I don't want to loosen the system security just for IE8, as the system works fine on anything more upto date. Getting all the clients to apply the hotfix is difficult at best, and impossible at worst. We need to support IE8 in the system, at least for now. So: 1: Does the detailed hotfix have any implications for the security at the browser end in IE8 - does it mean the file will be cached? (in a place other than where the user saves the file). 2: Is there some way I can get these files downloadable with a change at the server end that doesn't break the security side of things?

  • How can I store all my level data in a single file instead of spread out over many files?

    - by Jon
    I am currently generating my level data, and saving to disk to ensure that any modifications done to the level are saved. I am storing "chunks" of 2048x2048 pixels into a file. Whenever the player moves over a section that doesn't have a file associated with the position, a new file is created. This works great, and is very fast. My issue, is that as you are playing the file count gets larger and larger. I'm wondering what are techniques that can be used to alleviate the file count, without taking a performance hit. I am interested in how you would store/seek/update this data in a single file instead of multiple files efficiently.

  • Opening / using WUBI after downloading

    - by Jon
    I have no problem downloading WUBI either using Firefox or IE. Either way, however, when I try to run or open it, I get a message to the effect that the file cannot run because the configuration is incorrect and "re-installing the file may help" (which it doesn't - I've tried several times). What am doing wrong ? I am running XP Pro. (Note: my Ubuntu CD works just fine but I want to install Ubuntu inside Windows).

  • How do I get the Netgear N150 USB wifi adapter working on 12.04?

    - by Jon
    Just installed latest version of ubuntu. I'm using a Netgear N150 Wireless USB Micro Adapter WNA1000M which keeps asking for network password over and over. I read elsewhere that I needed to install the latest driver for my chipset (RTL8188CUS) which I have and still no joy. If I run the steps listed in this thread while connected through ethernet, the wireless will connect just fine. If I disconnect the ethernet, the wifi will even continue to work, but after a restart or two I will lose connection. If I repeat the steps listed in the aforementioned thread, it will not re-connect wifi unless I run those steps while connected to ethernet.......so strange...

  • How do I access and enable more icons to be in the system tray?

    - by Jon
    So I'm messing around with Natty a little, and I noticed that all the apps that would normally use the system tray (or "notification area"?) aren't displaying there. Is that a bug, or is that the way it's going to be? I heard something about Ubuntu getting rid of that feature entirely. Is there a way to add it back? I mean, I didn't really like it, either, especially when there were apps that used it unnecessarily, but I can't use CryptKeeper at all now, or easycrypt, and I don't know whether Dropbox has synced without opening Nautilus.

  • How can I restart compiz from tty? (& Related, how can I set up a fallback WM?)

    - by Jon
    So I'm testing Natty, and Compiz keeps crashing on me. I expect this sort of thing from alpha software, of course, but it doesn't always give me the option to restart compiz, and for some reason doesn't have a fallback WM configured. Without a window manager, all my programs are still running, but they're not accepting input from the keyboard, and I can't switch between them. I can, however, press Ctrl+Alt+F1 and get a terminal, and I can killall Xorg to reset everything, but I'd rather just reset compiz if possible. If I try typing compiz --replace there in the tty, it complains "fatal--couldn't open display." Is there a way to have tty1 restart compiz? Like compiz --replace --display=something? Additionally, is there a way to configure a fallback window manager so that there's an easier way to recover from compiz crashing?

  • Calculating the rotational force of a 2D sprite

    - by Jon
    I am wondering if someone has an elegant way of calculating the following scenario. I have an object of (n) number of squares, random shapes, but we will pretend they are all rectangles. We are dealing with no gravity, so consider the object in space, from a top down perspective. I am applying a force to the object at a specific square (as illustrated below). How do I calculate the rotational angle, based on the force being applied, at the location being applied. If applied in the center square, it would go straight. How should it behave the further I move from the center? How do I calculate the rotational velocity?

  • PHP, when to use iterators, how to buffer results?

    - by Jon L.
    When is it best to use Iterators in PHP, and how can they be implemented to best avoid loading all objects into memory simultaneously? Do any constructs exist in PHP so that we can queue up results of an operation for use with an Iterator, while again avoiding loading all objects into memory simultaneously? An example would be a curl HTTP request against a REST server In the case of an HTTP request that returns all results at once (a la curl), would we be better off to go with streaming results, and if so, are there any limitations or pitfalls to be aware of? If using streaming, is it better to replace curl with a PHP native stream/socket? My intention is to implement Iterators for a REST client, and separately a document ORM that I'm maintaining, but only if I can do so while gaining benefits from reduced memory usage, increased performance, etc. Thanks in advance for any responses :-)

  • What's the best way to explain branching (of source code) to a client?

    - by Jon Hopkins
    The situation is that a client requested a number of changes about 9 months ago which they then put on hold with them half done. They've now requested more changes without having made up their mind to proceed with the first set of changes. The two sets of changes will require alterations to the same code modules. I've been tasked with explaining why them not making a decision about the first set of changes (either finish them or bin them) may incur additional costs (essentially because the changes would need to be made to a branch then if they proceed with the first set of changes we'd have to merge them to the trunk - which will be messy - and retest them). The question I have is this: How best to explain branching of code to a non-technical client?

  • Is there a mirror for the daily Natty ISO (/daily-live/current) in Asia?

    - by Jon
    I've been trying to download Natty for days now, but either the internet here in Vietnam is totally shot or the Ubuntu CD server has a lot of traffic, because I can't get it to download faster than about 15Kbps. Does anyone know of a mirror, preferably close to Vietnam, where I could download (zsync) this image faster? Googling hasn't helped me, nor has Ubuntu's list of mirrors (I get stuck in a rabbithole of FTP folders, and nothing seems to point to the daily image).

  • Best language or tool for automating tedious manual tasks [closed]

    - by Jon Hopkins
    We all have tasks that come up from time to time that we think we'd be better off scripting or automating than doing manually. Obviously some tools or languages are better for this than others - no-one (in their right mind) is doing a one off job of cross referencing a bunch of text lists their PM has just given them in assembler for instance. What one tool or language would you recommend for the sort of general quick and dirty jobs you get asked to do where time (rather than elegance) is of the essence? Background: I'm a former programmer, now development manager PM, looking to learn a new language for fun. If I'm going to learn something for fun I'd like it to be useful and this sort of use case is the most likely to come up.

  • USB (wireless) keyboard not recognised during install

    - by Jon C
    I'm just trying my first trip into the world of Ubuntu. Trying to install from CD on to a virgin machine, I get the initial language prompt, select 'English', I get the Ubuntu install options, select 'Install Ubuntu Server'. I'm then presented with a further 'Language for installation' screen. At this point my keyboard stops working...! Some specifics: I'm using a Logitech wireless USB keyboard - it works fine on another machine; Machine is a ProLiant Micorserver N54L (No PS/2 ports); BIOS USB support is set to Legacy. Any ideas...? Thanks, Jonathan

  • HP G42 Ubuntu live cd failure

    - by Jon
    Ok, I have tried every option under the sun. I have surfed through the internet for a good 3 hours straight and to no effect. I installed ubuntu on my HP G42 laptop, it worked fine, then when I tried installing the standard after installation updates my wifi failed. In my attempt to fix my wi-fi I rebooted my laptop, when I rebooted I was stuck on a black screen with nothing that I tried to fix it helping the situation. So I then tried to fix it by reinstalling Ubuntu. When I attempted to boot into the live ccd it failed leaving with the now familar black screen. After numerous attempts using instructions from live cd and instal failure blank screen... page and replacing my hard drive at a cost of $65 I am coming here for help. As for the actual DVD that I tried installing ubuntu from it was able to install ubuntu on a mac just fine after my issues on the HP. After installing the hard drive I loaded up windows just fine but I don't want windows I want ubuntu, can you please provide instructions on how to install ubuntu?

  • Using Single Image for Map in 2D Platformer

    - by Jon
    I'm fairly new to game development, and have been messing around with Slick2D. Currently, my map consists of objects that are represented as rectangles. If I wanted to use am image simlar to: How would I be able to use this image to make a level? That question is a bit vague, but like I said, I'm new to game development and am not familiar with terminology or procedures. But going along with this question, how would I also use non-rectangular objects/platforms? Thanks

  • Server asks for username and password on boot

    - by Jon
    I installed the Ubuntu server 12.04 easily, however, when I boot it asks for a username and password. I don't know my previous username or password from Windows XP. I am currently trying to install any version of Ubuntu I have in my arsenal to recover the PC, but all intents so far have failed. They worked on other computers but not on this one, the error I get is No DEFAULT or UI configuration directive found! I have tried all the solutions found on this site but to no avail. I don't have a Windows Ultimate boot disk and I'm out of CDs to burn. I can, however, make live USBs. Any Suggestions?

  • How can I get my battery level to display in the notification area (system tray)?

    - by Jon
    I'm trying to use the Awesome window manager with GNOME, i.e. running gnome-session --session=ubuntu on login, and it works great for the most part, except for the fact that the notification area/systray is missing a battery indicator. There's the Network Manager applet (nm-applet), a keyboard icon for switching keyboard layouts, but no battery icon as I would've hoped. I thought the command would be something like gnome-power-manager,

  • How to determine collision direction between two rectangles?

    - by Jon
    I am trying to figure out how to determine the direction a collision occurs between two rectangles. One rectangle does not move. The other rectangle has a velocity in any direction. When a collision occurs, I want to be able to set the position of the moving rectangle to the point of impact. I seem to be stuck in determining from what direction the impact occurs. If I am moving strictly vertically or horizontally I manage great detection. But when moving in both directions at the same time, strange things happen. What is the best way to determine what direction a collision occurs between two rectangles?

  • IP fail-over address. Do i need it?

    - by Jon
    I received an email from my web hosting provider where i have 2 dedicated servers saying that from now on I have to pay for my IP fail-over addresses. The server we have hosts a tool used internally by our company. Traffic to it is quite low. No more than 3 people will use it at the same time. If something happens we can wait a day to have the tool up and running again. Is it worth having these fail-over addresses? thanks

  • Stop IIS 7 Application Pool from build script

    - by Andrew Hanson
    How can I stop and then restart an IIS 7 application pool from an MSBuild script running inside TeamCity. I want to deploy our nightly builds to an IIS server for out testers to view. I have tried using appcmd like so: appcmd stop apppool /apppool.name:MYAPP-POOL ... but I have run into elevation issues in Windows 2008 that so far have stopped me from being able to run that command from my TeamCity build process because Windows 2008 requires elevation in order to run appcmd. If I do not stop the application pool before I copy my files to the web server my MSBuild script is unable to copy the files to the server. Has anybody else seen and solved this issue when deploying web sites to IIS from TeamCity?
