• Good practice on Visual Studio Solutions

  - by JonWillis

  Hopefully a relativity simple question. I'm starting work on a new internal project to create tractability of repaired devices within the buildings. The database is stored remotely on a webserver, and will be accessed via web API (JSON output) and protected with OAuth. The front end GUI is being done in WPF, and the business code in C#. From this, I see the different layers Presentation/Application/Datastore. There will be code for managing all the authenticated calls to the API, class to represent entities (business objects), classes to construct the entities (business objects), parts for WPF GUI, parts of the WPF viewmodels, and so on. Is it best to create this in a single project, or split them into individual projects? In my heart I say it should be multiple projects. I have done it both ways previously, and found testing to be easier with a single project solution, however with multiple projects then recursive dependencies can crop up. Especially when classes have interfaces to make it easier to test, I've found things can become awkward.

• How can I get the touch screen working on a motion computing m1400

  - by pgcudahy

  I picked up a motion computing m1400 for cheap and was successful in getting 11.04 installed on it but have run into trouble getting the touch screen to work. This is one of the older tablet pcs that need a special pen for the touch screen. There are instructions out there for older versions of Ubuntu but they usually rely on a package called wacom-tools that is no longer in the repos. Is there any support for these old tablets or has time passed them by?

• Make a animation path separated by clicks

  - by Tomáš Zato

  I have a long text on powerpoint slide. Instead of separating it on multiple slides, I made an animation that moves it up using animation path, so that text hidden at bottom appears while text on top goes off screen. However, I need more move animations to reaveal more text (the text takes more than 2 screens). This means, I need two (or more) animation paths (of the same length) and I want them to move obejct from position, where the last path has left it. Instead, multiple animations always operate with objects original position. That's useless. You can download test document, where I made an example of what I want: animation test.pptx

• Higher Performance With Spritesheets Than With Rotating Using C# and XNA 4.0?

  - by Manuel Maier

  I would like to know what the performance difference is between using multiple sprites in one file (sprite sheets) to draw a game-character being able to face in 4 directions and using one sprite per file but rotating that character to my needs. I am aware that the sprite sheet method restricts the character to only be able to look into predefined directions, whereas the rotation method would give the character the freedom of "looking everywhere". Here's an example of what I am doing: Single Sprite Method Assuming I have a 64x64 texture that points north. So I do the following if I wanted it to point east: spriteBatch.Draw( _sampleTexture, new Rectangle(200, 100, 64, 64), null, Color.White, (float)(Math.PI / 2), Vector2.Zero, SpriteEffects.None, 0); Multiple Sprite Method Now I got a sprite sheet (128x128) where the top-left 64x64 section contains a sprite pointing north, top-right 64x64 section points east, and so forth. And to make it point east, i do the following: spriteBatch.Draw( _sampleSpritesheet, new Rectangle(400, 100, 64, 64), new Rectangle(64, 0, 64, 64), Color.White); So which of these methods is using less CPU-time and what are the pro's and con's? Is .NET/XNA optimizing this in any way (e.g. it notices that the same call was done last frame and then just uses an already rendered/rotated image thats still in memory)?

• Altering the Windows 7 grouping thumbnail preview

  - by russ

  I like the windows 7 grouping behaviour for multiple similar windows, except when I have multiple Explorer windows open. In this case, showing thumbnails of each open explorer window is next to useless, and I would like to know how to either: Disable thumbnail display completely (but preserve the grouping behaviour) Disable thumbnail display for a subset of programs (all explorer.exe instances) Change the number of similar programs that are open before the grouping behaviour falls back on a more sensible text preview when hovering over the taskbar icon (currently 14 or over) I don't particularly want to disable any other features of windows to get this behaviour, so disabling the theme compleletely isn't what I want to do. I definitely want to keep the grouping behaviour. Its just those thumbnail previews I would like to alter. Here are some screen shots of what I don't want, and what I do want: http://dl.dropbox.com/u/13184372/StackOverflow/BadGrouping.png http://dl.dropbox.com/u/13184372/StackOverflow/GoodGrouping.png

• Automatic switching between monitor configurations

  - by Michael Aquilina

  I have a laptop and an external monitor and i was wondering if there was a simple approach to switching between multiple monitor configurations based on the detected available displays. For example: When i am at home and i plug in my external monitor i would like this to automatically become enabled and the laptop screen to become disabled. As soon as i pull out the display cable for the external monitor, i would like the laptop screen to automatically become enabled. I was expecting this to just "work" just like it does in windows - but it seems to be much harder than that. I am aware of the xrandr command to turn displays on and off but i cannot seem to find a way to get this to work the way i describe above. I had also found this post about switching between multiple monitor configurations and the results seem a bit inconclusive. However i was hoping that with xrandr there would be a simpler solution. For me, the fact that when i pull out my external monitor the screen just goes black and i get an error message is a big issue holding me back from making the complete switch to linux as i move around alot as a student. My OS of choice is currently Kubuntu 12.04 but i am willing to change to something else if it provides a better way of setting up the described setup.

  I have installed Ubuntu 12.04 on Dell Vostro 1520 Laptop. But found Wifi is hardware locked, though wifi is working perfectly fine with Windows 7 in the same laptop. I tried to upgrade the drivers as mentioned in other posts/forums but could not resolve the issue. I had the similar problem with versions 11.* as well. Last time the Wifi worked with 10.* version. Please help me to get it resolved.

• Cloud hosting and single hardware point of failure?

  - by PeterB

  From talking to sales I thought Rackspace Cloud was running on a SAN and compute nodes (as VMWare's offerings do), only to find out it doesn't, so when the host server goes down for maintenance all cloud servers on the server go down (in our case for 2.5 hours). I understand Amazon EC2 also has this single-server point of failure. Which cloud hosting solutions don't rely on a single server? I've yet to find a list by architecture Is there a term that distinguishes between these types of 'cloud'? Is one of these 'grid computing' and the other 'virtualisation'? Can a SAN backed solution provide the same reliability as 2 mirrored cloud servers on (say) Rackspace Cloud? I am more familiar with the VMWare architecture and would like to understand the advantages and disadvantages of each approach. I understand the standard architecture is to have multiple cloud servers and mirrored data between them; until we need multiple database servers I'm wondering if a SAN/node hosting solution would provide the lack of downtime we need without the added complexity.

• What a .NET developer should know or practice (know how to do)? [closed]

  - by Olav

  I would like to have a list of basic tasks that .NET developers of different flavors using Visual Studio/SQL Server should be able to do. Ideally with a kind of lab environment where I could practice. VB.NET or C#, latest versions of ASP.NET, WPF and Silverlight. I am looking for small practical "atomic" tasks (like adding a db connection for example) I am looking for some existing labs/lists rather than specific points in the answers. (But I would not mind collaborating in developing material).

• how to store and retrieve/generate UI?

  - by thindery

  I'm working on a site that will have hundreds, and eventually thousands, of paper products that users can customize online. Here is a very simple sample of what needs to be generated based on the product id: demo. This is a very simple version. I plan on replacing text fields with prettier elements(like the slider on tab 3). I imagine most of this can be achieved via jquery. So basically a product will have multiple pages(tabs), with multiple form elements on each page. I've never done a large scale project like this before and I am looking for ideas/suggestions for how I can store the info for each product that needs to be generated to create the UI. For each product, I need to store how many pages there are, what form fields are on each page, and the order of the fields on the page. As well as setting default text values and form options(font size, etc). Then with all this info stored somewhere, I can have the web app retrieve it and generate the UI with text fields, sliders, and other jquery-ish form enhancements, for that particular product. Can anyone toss out some suggestions, links, blogs, tutorials? I'm not really sure where to begin with this or what I need to start to investigate. I have experience with php, mysql, javascript, jquery, html, css, and that is really about it. I'm open to learning(and would enjoy exploring) new frameworks, programming, etc that will really get this web app working correctly, efficiently, and effectively. Maybe I should start looking into a mvc framework? like i said, i really have no idea what is the best approach. please let me know your suggestions!

• How to use ccache selectively?

  - by Anonymous

  I have to compile multiple versions of an app written in C++ and I think to use ccache for speeding up the process. ccache howtos have examples which suggest to create symlinks named gcc, g++ etc and make sure they appear in PATH before the original gcc binaries, so ccache is used instead. So far so good, but I'd like to use ccache only when compiling this particular app, not always. Of course, I can write a shell script that will try to create these symlinks every time I want to compile the app and will delete them when the app is compiled. But this looks like filesystem abuse to me. Are there better ways to use ccache selectively, not always? For compilation of a single source code file, I could just manually call ccache instead of gcc and be done, but I have to deal with a complex app that uses an automated build system for multiple source code files.

• How to persuade C fanatics to work on my C++ open source project?

  - by paperjam

  I am launching an open-source project into a space where a lot of the development is still done Linux-kernel-style, i.e. C-language with a low-level mindset. There are multiple benefits to C++ in our space but I fear those used to working in C will be scared off. How can I make the case for the benefits of C++? Specifically, the following C++ attributes are very valuable: concept of objects and reference-counting pointers - really don't want to have to malloc(sizeof(X)) or memcpy() structs templates for specialising whole bodies of code with specific performance optimizations and for avoiding duplication of code. template metaprogramming related to the above syntactic sweetness available (e.g. operator overloading, to be used in very small doses) STL Boost libraries Many of the knee-jerk negative reactions to C++ are illfounded. Performance does not suffer: modern compilers can flatten dozens of call stack levels and avoid bloat through wide use of template specializations. Granted, when using metaprogramming and building multiple specializations of a large call tree, compile time is slower but there are ways to mitigate this. How can I sell C++?

• Where has /lib/udev/keymap gone? How do I adjust keymaps in Trusty?

But I face following error: sudo: /lib/udev/keymap: command not found I have udev version 204-5ubuntu20.2 (the version found in Trusty) I noticed that this version doesn't include keymap tool. But I notices that greater udev versions (which available for Debian, for example) include this tool. Could somebody explain this diff for me? =) And what should I do in this case - install package from Debian repo?

• What TLDs should I use for my NS records for redundancy? (DNSSEC support required)

  - by makerofthings7

  Question As a general practice, is it a good idea to use multiple TLDs for the name servers? How should I choose between which TLD would be a good candidate for being the root server for my NS name? More Info I am switching over 800 DNS zones to an outsourced DNS provider. I originally planned on setting the zone names to nsX.company.com, but think it would be best to have multiple TLDs such as .net , .org and .info Since I plan on supporting DNSSec at company.com I think all the 1st tier Name servers must support it as well. Part of the inspiration for this question came from our provider UltraDNS. In their configuration screen for our domains, they actively verify and alert us if our name servers aren't exactly: pdns1.ultradns.net pdns2.ultradns.net pdns3.ultradns.org pdns4.ultradns.org pdns5.ultradna.info pdns6.ultradns.co.uk

• Digitally Signed Malware on the Rise

  Brought to the forefront in 2010 with Stuxnet, the infamous worm aimed at sabotaging industrial infrastructure, the use of stolen digital certificates is relatively new. Stuxnet's creators digitally signed its rootkit components with stolen certificates from JMicron and RealTek, a pair of semiconductor manufacturers. The worm's existence and complexity caught the security community by surprise. In fact, many researchers predicted that malware creators would begin adopting the same technique to work around driver signature enforcement employed by Microsoft in its 64-bit versions of Windows V...
