  • 7 Ways To Free Up Hard Disk Space On Windows

    - by Chris Hoffman
    Hard drives are getting larger and larger, but somehow they always seem to fill up. This is even more true if you’re using a solid-state drive (SSD), which offers much less hard drive space than traditional mechanical hard drives. If you’re hurting for hard drive space, these tricks should help you free up space for important files and programs by removing the unimportant junk cluttering up your hard disk.

  • Software engineering project idea feedback [on hold]

    - by Chris Sewell
    I'm a third year student currently undergoing my project/dissertation section of my degree. I have drafted a proposal for my final year project and would appreciate any feedback. The feedback can be anything constructive either specific to this proposal, the area that I will be working and researching in or my ideas. I will accept all input. Aims My aim is to attempt a proof of concept and prototype a runtime-as-a-service (RaaS). This cloud based runtime will allow clients to dynamically offload tasks or create cloud applications. Currently software-as-a-service (SaaS) cloud applications are purpose built and have a predefined scope in which they can assist or serve the client; this scope cannot be changed without physical alteration to the client and server software. With RaaS the client potentially could define any task it wanted at any time depending on its environment variables, the client and server would then communicate parameters and returns for that task. For the client to utilize a RaaS it must be able to conceive and then define a task using an appropriate XML vocabulary. As the scope of the cloud solution is defined by the client at its runtime, the cloud solution only has to exist for as long as the client requires it to as opposed to a client using a dedicated service. Deliverables The crux of the project will require an XML vocabulary in which the client and server will communicate. I’ll prototype the server application that will dynamically create and manage cloud solutions. The solution will be coded using an interpreted language, such as python or javascript, which can evaluate expressions in runtime or a language that can dynamically compile such as C# or Java. As a further proof of concept I will also produce a mock client that offloads tasks to the server. The report will attempt to explain the different flavours of cloud computing solutions including infrastructure-as-a-service (IaaS), platform-as-a-service (PaaS) and SaaS including real world examples and where the use of a RaaS could have improved the overall example solution. Disclaimer: I'm not requesting stakeholders in my project nor am I delegating work. Any materials other than feedback, advice or directions will not be utilized.

  • HTG Explains: Learn How Websites Are Tracking You Online

    - by Chris Hoffman
    Some forms of tracking are obvious – for example, websites know who you are if you’re logged in. But how do tracking networks build up profiles of your browsing activity across multiple websites over time? Tracking is generally used by advertising networks to build up detailed profiles for pinpoint ad-targeting. If you’ve ever visited a business’ website and seen ads for that business on other websites later, you’ve seen it in action.

  • My First 5K

    - by Chris Williams
    So… yesterday I registered for my first 5K event. It’s in Eden Prairie this weekend. It’s a pretty major milestone for me, especially since I absolutely hate running with a passion. Still, I have to admit I’m rather excited about it. Given that this is my first event, I have no illusions about winning. My immediate goal is simple… don’t come in last. I’ll let you know how it goes.

  • Antenna Aligner part 2: Finding the right direction

    - by Chris George
    Last time I managed to get "my first app(tm)" built, published and running on my iPhone. This was really cool, a piece of my code running on my very own device. Ok, so I'm easily pleased! The next challenge was actually trying to determine what it was I wanted this app to do, and how to do it. Reverting back to good old paper and pen, I started sketching out designs for the app. I knew I wanted it to get a list of transmitters, then clicking on a transmitter would display a compass type view, with an arrow pointing the right way. I figured there would not be much point in continuing until I know I could do the graphical part of the project, i.e. the rotating compass, so armed with that reasoning (plus the fact I just wanted to get on and code!), I once again dived into visual studio. Using my friend (google) I found some example code for getting the compass data from the phone using the PhoneGap framework. // onSuccess: Get the current heading // function onSuccess(heading) {    alert('Heading: ' + heading); } navigator.compass.getCurrentHeading(onSuccess, onError); Using the ripple mobile emulator this showed that it was successfully getting the compass heading. But it didn't work when uploaded to my phone. It turns out that the examples I had been looking at were for PhoneGap 1.0, and Nomad uses PhoneGap 1.4.1. In 1.4.1, getCurrentHeading provides a compass object to onSuccess, not just a numeric value, so the code now looks like // onSuccess: Get the current magnetic heading // function onSuccess(heading) {    alert('Heading: ' + heading.magneticHeading); }; navigator.compass.getCurrentHeading(onSuccess, onError); So the lesson learnt from this... read the documentation for the version you are actually using! This does, however, lead to compatibility problems with ripple as it only supports 1.0 which is a real pain. I hope that the ripple system is updated sometime soon.

  • How can I resize an external USB NTFS partition?

    - by chris
    I have a new USB drive which came with a single NTFS partition. How can I shrink that so that I can create an ext4 partition? gparted does not seem to have the "Resize" option highlighted. Update: After following the directions below, after unmounting I am still not able to resize the partition. There is a warning though: "Unable to find mount point. Unable to read the contents of this file system! Because of this, some operations may be unavailable. The following list of software packages is required for ntfs file system support: ntfsprogs". However, with the partition mounted, I can read & write to the file system on the drive just fine, and ntfsprogs is installed and current. What's next?

  • Am I the only one this anal / obsessive about code? [closed]

    - by Chris
    While writing a shared lock class for sql server for a web app tonight, I found myself writing in the code style below as I always do: private bool acquired; private bool disposed; private TimeSpan timeout; private string connectionString; private Guid instance = Guid.NewGuid(); private Thread autoRenewThread; Basically, whenever I'm declaring a group of variables or writing a sql statement or any coding activity involving multiple related lines, I always try to arrange them where possible so that they form a bell curve (imagine rotating the text 90deg CCW). As an example of something that peeves the hell out of me, consider the following alternative: private bool acquired; private bool disposed; private string connectionString; private Thread autoRenewThread; private Guid instance = Guid.NewGuid(); private TimeSpan timeout; In the above example, declarations are grouped (arbitrarily) so that the primitive types appear at the top. When viewing the code in Visual Studio, primitive types are a different color than non-primitives, so the grouping makes sense visually, if for no other reason. But I don't like it because the right margin is less of an aesthetic curve. I've always chalked this up to being OCD or something, but at least in my mind, the code is "prettier". Am I the only one?

  • My First 5K, the recap.

    - by Chris Williams
    It was a nice day to be outside (and trust me, those aren't words you'll hear from me often.) I got to the site around 7:45, hit the pre-reg table and got my number along with a goody bag full of coupons for racing gear, a water bottle and a tshirt. Oh and a map. Stashed all that stuff in the jeep, emptied my pockets of everything but my iPhone and my jeep key, and proceeded to walk around for a bit as people started showing up and signing in. It was fairly breezy, and there was definitely a storm coming... but it was anyone's guess on when it would actually arrive. It was interesting to see everyone who was participating. If I had to guess, I would say the event was 60-70% women, with a pretty broad distribution of age... as young as 13 to well over 60 (in both genders.) I don't know exactly how many folks were there, but it was well over 300. Eventually it was time to kick things off, and everyone made their way to the start line. All of the 5k and 10k runners were mixed together, starting at the same time. All the walkers and the people with strollers or dogs were in the back. It was pretty chaotic at first, once things started, but it thinned out fairly quickly. The 10k people and the hardcore runners sped ahead of everyone else and the walkers gradually lagged behind. The 5K course was pretty nice, winding around a lake down in Eden Prairie. The 10K course overlapped most of ours, but branched off a couple times too. I didn't run the whole time, but I started the race running and I ended it running, and did a mix of walking and running along the way. I met my goals, which were a) don't ever stop and b) don't be last. The weather managed to hold out for the entire race. It never got too hot, there was a nice breeze and it was mostly overcast. Pretty much perfect in my book. About 20-30 minutes after I left, the rain came down pretty hard. I had a good time, and will most likely do more of them. We'll see.

  • How To Extract Individual Files From a Windows 7 System Image Backup

    - by Chris Hoffman
    Windows 7’s backup control panel has the ability to create full system image backups. While Windows says you can’t restore individual files from these backups, there’s a way to browse the contents of a system image and extract individual files. System image backups are meant for restoring an entire system. If you want to easily restore individual files, you should use another type of backup – but you don’t have to restore an entire system image to get a few important files back.

  • useradd instead of adduser,

    - by Chris at Well
    So I installed Ubuntu 13.04, set up sftp, that's all good. Setting up vsftpd for regular FTP users (we need those too, sadly. sftp isn't for good for all our purposes), i accidently used useradd to create one of the users instead of adduser. This user can't log in to frig all. I tried to delete the user and re-add it with adduser, no dice. It creates the user, but the permissions are frigged up. Any idea how I can completely undo a useradd, so that I can adduser this person and have everything coming up Milhouse again? Sorry boys, I frigged up hard.

  • Screenshot Tour: Ubuntu Touch 14.04 on a Nexus 7

    - by Chris Hoffman
    Ubuntu 14.04 LTS will “form the basis of the first commercially available Ubuntu tablets,” according to Canonical. We installed Ubuntu Touch 14.04 on our own hardware to see what those tablets will be like. We don’t recommend installing this yourself, as it’s still not a polished, complete experience. We’re using “Ubuntu Touch” as shorthand here — apparently this project’s new name is “Ubuntu For Devices.” The Welcome Screen Ubuntu’s touch interface is all about edge swipes and hidden interface elements — it has a lot in common with Windows 8, actually. You’ll see the welcome screen when you boot up or unlock a Ubuntu tablet or phone. If you have new emails, text messages, or other information, it will appear on this screen along with the time and date. If you don’t, you’ll just see a message saying “No data sources available.” The Dash Swipe in from the right edge of the welcome screen to access the Dash, or home screen. This is actually very similar to the Dash on Ubuntu’s Unity desktop. This isn’t a surprise — Canonical wants the desktop and touch versions of Ubuntu to use the same code. In the future, the desktop and touch versions of Ubuntu will use the same version of Unity and Unity will adjust its interface depending on what type of device your’e using. Here you’ll find apps you have installed and apps available to install. Tap an installed app to launch it or tap an available app to view more details and install it. Tap the My apps or Available headings to view a complete list of apps you have installed or apps you can install. Tap the Search box at the top of the screen to start searching — this is how you’d search for new apps to install. As you’d expect, a touch keyboard appears when you tap in the Search field or any other text field. The launcher isn’t just for apps. Tap the Apps heading at the top of the screen and you’ll see hidden text appear — Music, Video, and Scopes. This hidden navigation is used throughout Ubuntu’s different apps and can be easy to miss at first. Swipe to the left or right to move between these screens. These screens are also similar to the different panels in Unity on the desktop. The Scopes section allows you to view different search scopes you have installed. These are used to search different sources when you start a search from the Dash. Search from the Music or Videos scopes to search for local media files on your device or media files online. For example, searching in the Music scope will show you music results from Grooveshark by default. Navigating Ubuntu Touch Swipe in from the left edge anywhere on the system to open the launcher, a bar with shortcuts to apps. This launcher is very similar to the launcher on the left of Ubuntu’s Unity desktop — that’s the whole idea, after all. Once you’ve opened an app, you can leave the app by swiping in from the left. The launcher will appear — keep moving your finger towards the right edge of teh screen. This will swipe the current app off the screen, taking you back to the Dash. Once back on the Dash, you’ll see your open apps represented as thumbnails under Recent. Tap a thumbnail here to go back to a running app. To remove an app from here, long-press it and tap the X button that appears. Swipe in from the right edge in any app to quickly switch between recent apps. Swipe in from the right edge and hold your finger down to reveal an application switcher that shows all your recent apps and lets you choose between them. Swipe down from the top of the screen to access the indicator panel. Here you can connect to Wi-Fi networks, view upcoming events, control GPS and Bluetooth hardware, adjust sound settings, see incoming messages, and more. This panel is for quick access to hardware settings and notifications, just like the indicators on Ubuntu’s Unity desktop. The Apps System settings not included in the pull-down panel are available in the System Settings app. To access it, tap My apps on the Dash and tap System Settings, search for the System Settings app, or open the launcher bar and tap the settings icon. The settings here a bit limited compared to other operating systems, but many of the important options are available here. You can add Evernote, Ubuntu One, Twitter, Facebook, and Google accounts from here. A free Ubuntu One account is mandatory for downloading and updating apps. A Google account can be used to sync contacts and calendar events. Some apps on Ubuntu are native apps, while many are web apps. For example, the Twitter, Gmail, Amazon, Facebook, and eBay apps included by default are all web apps that open each service’s mobile website as an app. Other applications, such as the Weather, Calendar, Dialer, Calculator, and Notes apps are native applications. Theoretically, both types of apps will be able to scale to different screen resolutions. Ubuntu Touch and Ubuntu desktop may one day share the same apps, which will adapt to different display sizes and input methods. Like Windows 8 apps, Ubuntu apps hide interface elements by default, providing you with a full-screen view of the content. Swipe up from the bottom of an app’s screen to view its interface elements. For example, swiping up from the bottom of the Web Browser app reveals Back, Forward, and Refresh buttons, along with an address bar and Activity button so you can view current and recent web pages. Swipe up even more from the bottom and you’ll see a button hovering in the middle of the app. Tap the button and you’ll see many more settings. This is an overflow area for application options and functions that can’t fit on the navigation bar. The Terminal app has a few surprising Easter eggs in this panel, including a “Hack into the NSA” option. Tap it and the following text will appear in the terminal: That’s not very nice, now tracing your location . . . . . . . . . . . .Trace failed You got away this time, but don’t try again. We’d expect to see such Easter eggs disappear before Ubuntu Touch actually ships on real devices. Ubuntu Touch has come a long way, but it’s still not something you want to use today. For example, it doesn’t even have a built-in email client — you’ll have to us your email service’s mobile website. Few apps are available, and many of the ones that are are just mobile websites. It’s not a polished operating system intended for normal users yet — it’s more of a preview for developers and device manufacturers. If you really want to try it yourself, you can install it on a Wi-Fi Nexus 7 (2013), Nexus 10, or Nexus 4 device. Follow Ubuntu’s installation instructions here.

  • How to Run PowerShell Commands on Remote Computers

    - by Chris Hoffman
    PowerShell Remoting allows you to run individual PowerShell commands or access full PowerShell sessions on remote Windows systems. It’s similar to SSH for accessing remote terminals on other operating systems. PowerShell is locked-down by default, so you’ll have to enable PowerShell Remoting before using it. This setup process is a bit more complex if you’re using a workgroup – for example, on a home network — instead of a domain.

  • Enemy Spawning method in a Top-Down Shooter

    - by Chris Waters
    I'm working on a top-down shooter akin to DoDonPachi, Ikaruga, etc. The camera movement through the world is handled automatically with the player able to move inside of the camera's visible region. Along the way, enemies are scripted to spawn at particular points along the path. While this sounds straightforward, I could see two ways to define these points: Camera's position: 'trigger' spawning as the camera passes by the points Time along path: "30 seconds in, spawn 2 enemies" In both cases, the camera-relative positions would be defined as well as the behavior of the enemy. The way I see it, the way you define these points will directly affect how the 'level editor', or what have you, will work. Would there be any benefits of one approach over the other?

  • Extending Expression Blend 4 &amp; Blend for Visual Studio 2012

    - by Chris Skardon
    Just getting this off the bat, I presume this will also work for Blend 5, but I can’t confirm it… Anyhews, I imagine you’re here because you want to know how to create an addin for Blend, so let’s jump right in there! First, and foremost, we’re going to need to ensure our development environment has the right setup, so the checklist: Visual Studio 2012 Blend for Visual Studio 2012 OK, let’s create a new project (class library, .NET 4.5): Hello.Extension The ‘.Extension’ bit is very very important. The addin will not work unless it is named in this way. You can put whatever you want at the front, but it has to have the extension bit. OK, so now we have a solution with one project. To this project we need to add references to the following things: Microsoft.Expression.Extensibility (from c:\program files\Microsoft Visual Studio 11.0\Blend\   -- x86 folder if you are on an x64 windows install) Microsoft.Expression.Framework (same location as above) PresentationCore PresentationFramework WindowsBase System.ComponentModel.Composition Got them? ACE. Let’s now add a project to contain our control, so, create a new WPF Application project, cunningly named something like ‘Hello.Control’… (I’m creating a WPF application here, because I’m too lazy to dig up the correct references, and this will add all the ones I need ) Once that is created, delete the App.xaml and MainWindow.xaml files, we won’t be needing them. You will also need to change the properties of the project itself, so it is only a class library. Once that is done, let’s add a new UserControl, which will be this: <UserControl x:Class="Hello.Control.HelloControl" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="300"> <Grid> <TextBlock Text="HELLO!!!"/> </Grid> </UserControl> Impressive eh? Now, let’s reference the WPF project from the Extension library. All that’s left now is to code up our extension… So, add a class to the Extension project (name wise doesn’t matter), and make it implement the IPackage interface from the Microsoft.Expression.Extensibility library: public class HelloExtension : IPackage { /**/ } We’ll implement the two methods we need to: public class HelloExtension : IPackage { public void Load(IServices services) { } public void Unload() { } } We’re only really concerned about the Load method in this case, as let’s face it, the extension we have doesn’t need to do a lot to bog off. The interesting thing about the Load method is that it receives an IServices instance. This allows us to get access to all the services that Expression provides, in this case we’re interested in one in particular, the ‘IWindowService’ So, let’s get that bad boy… private IWindowService _windowService; public void Load(IServices services) { _windowService = services.GetService<IWindowService>(); } Nailed it… But why? The WindowService allows us to register our UserControl with Blend, which in turn allows people to activate and see it, which is a big plus point. So, let’s do that… We’ll create an ‘Initialize’ method to create our new control, and add it to the WindowService: private HelloControl _helloControl; public void Initialize() { _helloControl = new HelloControl(); if (_windowService.PaletteRegistry["HelloPanel"] == null) _windowService.RegisterPalette("HelloPanel", _helloControl, "Hello Window"); } First we check that we’re not already registered, and if we’re not we register, the first argument is the identifier used by the service to, well, identify your extension. The second argument is the actual control, the third argument is the name that people will see in the ‘Windows’ menu of Blend itself (so important note here – don’t put anything embarrassing or (need I say it?) sweary…) There are only two things to do now - Call ‘Initialize()’ from our Load method, and Export the class This is easy money – add [Export(typeof(IPackage))] to the top of our class… The full code will (should) look like this: [Export(typeof (IPackage))] public class HelloExtension : IPackage { private HelloControl _helloControl; private IWindowService _windowService; public void Load(IServices services) { _windowService = services.GetService<IWindowService>(); Initialize(); } public void Unload() { } public void Initialize() { _helloControl = new HelloControl(); if (_windowService.PaletteRegistry["HelloControl"] == null) _windowService.RegisterPalette("HelloControl", _helloControl, "Hello Window"); } } If you build this and copy it to your ‘Extensions’ folder in Blend (c:\program files\microsoft visual studio 11.0\blend\) and start Blend, you should see ‘Hello Window’ listed in the Window menu: That as they say is it!
