• What Design Pattern To Replace 'CurrentStep' Variable

  - by Rob P.

  Tried to search but didn't know how to phrase it. I've got some code that is essentially... Private CurMajorStep as Integer = 0 Private CurMinorStep as Integer = 0 Public Sub PerformNextStep() Select Case iMajorStep Case 0 ThingOne() Case 1 ThingTwo() Case 2 ThingThree() Case 3 ThingFour() Case 4 AnythingElse() Case 5 Finish() End Select End Sub And then, in some of those, the CurMinorStep keeps track of the current state of that particular 'step'. I hope that all makes sense. The code is messy and I know it's going to be problematic to maintain. Can someone point me to a clean OO pattern to handle this?

• which is the cleaner way to do this simple while?

  - by user363834

  I'm learning c++ and I want to make clean and readable code and I was wondering which way is better (while is supposed to make the factorial of 9) : 1 - int main(){ int i = 1,r = i; while (i < 10) { r *= ++i; } 2 - int main(){ int i = 1,r = i; while (i < 10) { i++ r *= i } 1 may be harder to understand but it's 1 less line, is it worth it? and what about performance. Obviously it wouldn't matter in such a trivial example but it would be a good practice to make fast code from the begining.

• Artificial Intelligence Project - What language should I go for?

  - by Kremlin Yocepf

  Hi, I am a computer science student and I am going to work on an artificial intelligence project which will compose a musical tune according to the genre and mood inputs. Are the algorithms to be used for this project likely to be very resource-consuming? Would it make any difference (in terms of speed) if I choose to go with Java rather than C++? (Note : I know only these two languages and I am more comfortable with Java than C++.) NB : Sorry for my poor English. If someone can, please clean up this post wherever necessary. Thanks.

• VirtualBox snapshots

  - by CodeMedic

  Heres what happened. I had a snapshot on which I was working from within a linux VM. A friend requested a clean VM as a clone of mine. So I closed / shutdown my running VM, made a copy of the Disk1.vdi along with the snapshots ({uuid}.vdi). Then I restarted the VM and did merged snapshots, deleted my home directory and made a tar+bz2 for my friend. Then after I restored my backups, I am not able to mount my snapshot. The VM seems to boot from my version before snapshot. I cant seem to find a way to mount back my snapshot. Any idea how to make VirtualBox see the snapshot and mount it?

• char '0x8' what character is this?

  - by OHHAI

  I have a large amount of data in a database. When I attempt to read a certain portion of the data and generate some xml and send it to a webservice I get the following exception... The char '0x8' in 'java.lang.IllegalArgumentException'. I'm guessing it is some bad data, as it has worked perfectly for about 7 months but now some user uploaded some new data that seems to have some issues. Anyone know what character this is so I can just run a sql query and clean it from the db? Thanks in advance.

• Changing populated DataTable column data types

  - by TonE

  Hi, I have a System.Data.DataTable which is populated by reading a CSV file which sets the datatype of each column to string. I want to append the contents of the DataTable to an existing database table - currently this is done using SqlBulkCopy with the DataTable as the source. However, the column data types of the DataTable need to be changed to match the schema of the target database table, handling null values. I am not very familiar with ADO.NET so have been search for a clean way of doing this? Thanks.

• Is there a faster way to remove un-referenced controls from a Form's designer file?

  - by Eric

  I started looking into the designer file of one of my Forms and noticed that a lot of the old controls I thought I had deleted are still being instantiated but are not actually used on the form. Is there any easy way to clean up these controls from the designer file that are not being used? Right now I've printed out a list of all the private fields at the bottom of the designer file that reference the controls of the form. I'm going down the list one by one trying to determine if the control is actually used or not, and then deleting those that I find are not on the form. The document outline is useful for figuring out what controls are on the form, but this is still a rather tedious process. Does anyone have a better way?

• how can i introspect properties and model fields in django?

  - by shreddd

  I am trying to get a list of all existing model fields and properties for a given object. Is there a clean way to instrospect an object so that I can get a dict of fields and properties. class MyModel(Model) url = models.TextField() def _get_location(self): return "%s/jobs/%d"%(url, self.id) location = property(_get_location) What I want is something that returns a dict that looks like this: { 'id' : 1, 'url':'http://foo', 'location' : 'http://foo/jobs/1' } I can use model._meta.fields to get the model fields, but this doesn't give me things that are properties but not real DB fields.

• Linq to SQL DateTime values are local (Kind=Unspecified) - How do I make it UTC?

  - by ericsson007

  Isn't there a (simple) way to tell Linq To SQL classes that a particular DateTime property should be considered as UTC (i.e. having the Kind property of the DateTime type to be Utc by default), or is there a 'clean' workaround? The time zone on my app-server is not the same as the SQL 2005 Server (cannot change any), and none is UTC. When I persist a property of type DateTime to the dB I use the UTC value (so the value in the db column is UTC), but when I read the values back (using Linq To SQL) I get the .Kind property of the DateTime value to be 'Unspecified'. The problem is that when I 'convert' it to UTC it is 4 hours off. This also means that when it is serialized it it ends up on the client side with a 4 hour wrong offset (since it is serialized using the UTC).

• Can I un-assign (clear) all fields of an instance?

  - by Roman

  Is there a simple way to clear all fields of an instance from a an instance? I mean, I would like to remove all values assigned to the fields of an instance. ADDED From the main thread I start a window and another thread which controls state of the window (the last thread, for example, display certain panels for a certain period of time). I have a class which contains state of the window (on which stage the user is, which buttons he already clicked). In the end, user may want to start the whole process from the beginning (it is a game). So, I decided. So, if everything is executed from the beginning, I would like to have all parameter to be clean (fresh, unassigned). ADDED The main thread, creates the new object which is executed in a new thread (and the old thread is finished). So, I cannot create a new object from the old thread. I just have a loop in the second thread.

• Friday Fun: Favorite Games to Play in Chrome

  - by Asian Angel

  Online games can provide a perfect break while you are working and being able to choose from a multitude of games makes it even better. If you are a game addict then you will definitely want to have a look at the Game Button extension for Chrome. Game Button in Action Once the extension has finished installing you are ready to enjoy all that gaming goodness. To get started just click on the “Toolbar Button” and choose a game category. For our example we chose “Shooting Games”. Once you select a game category a new window will open. Towards the lower right corner you will be able to access a scrollable drop-down menu and choose the game that you would like to play. Note: Some of these games come with sounds that can not be turned off so you may want to have the volume lowered all the way or your speakers temporarily turned off if you are at work. For our first game we chose “Snowball Throw”. Notice that there is a nice variety such as “DinoKids – Archery” to games like “Secret Agent”. You can see that our game was nicely sized…not too small and not too large. Go go snowballs! This is definitely a fun one to try…the best approach for this one is to use one hand for clicking the mouse and the other hand for moving it at the same time. If desired you can post your score and see other high scores afterwards. For our second game we decided to try “Target Shooter Firing Range”. This one is definitely a little harder because you have to be extremely precise while moving as quickly as possible. Not too bad for the score but that is ok. You will certainly be able to have fun finding the games that will become your favorites while enjoying the nice variety. Conclusion If you love online games and want a good variety to choose from then the Game Button extension will make a nice addition to your browser.

• Turn Non-Resizeable Windows into Rezieable Windows

  - by Asian Angel

  Are you frustrated with Windows app windows that can not be resized at all? Now you can apply some “attitude adjustment” and resize those windows with ResizeEnable. Before Everyone is familiar with the many app windows in their Windows OS that simply can not be resized. What you need is cooperation, not attitude. For our example we chose the “Taskbar and Start Menu Properties Window”…notice the cursor in the lower right corner. No resizing satisfaction available at all… After The program comes in a zip file with three files as shown here. Once you have unzipped the program place it in an appropriate “Program Files Folder”, create a shortcut, and you are ready to go. There will be a “System Tray Icon” with only two “Context Menu” items…“About & Quit”. Here is a quick look at the “About Window” that tells you exactly what ResizeEnable does. Notice that it does state that you may occasionally have a window that may not respond correctly. Now back to our “Taskbar and Start Menu Properties Window”. Notice the resizing cursor in the lower right corner….time for some fun! During our test the “Taskbar and Start Menu Properties Window” was suddenly a dream to resize. Daring to stretch the window even further…now that is what you call “stretching” the window out in comparison to its’ original size! Think of all the windows that will be much easier to work with now… Conclusion If you have been frustrated with non-resizeable windows then ResizeEnable will certainly bring a smile to your face as you watch those windows suddenly become a lot more cooperative. This is definitely one app that is worth adding to your system.

• How to Add Proprietary Drivers to Ubuntu 10.04

  - by Matthew Guay

  Does the hardware on your Ubuntu system need proprietary drivers work at peak performance?  Today we take a look how easy version 10.04 makes it to install them. Ubuntu 10.04 finally automatically recognizes and installs drivers for most hardware today, it even recognized and configured Wi-Fi drivers correctly every time in our tests.  This is in contrast to the past, when it was often difficult to get hardware to work in Linux.  However, most video cards still need proprietary drivers from their manufacturer to get full hardware video acceleration. Even though Ubuntu doesn’t include any non-open source components, it still makes it easy to install proprietary drivers if you wish.  When you first install and boot into Ubuntu, you may see a popup informing you that “restricted” drivers are available. You may see a notification asking you if you’d like to install optional drivers from your graphics card manufacturer when you try to enable advanced desktop effects.  Click Enable to directly install the drivers right there. Or, you can select the tray icon from the first popup, and click Install drivers. Alternately, if the tray icon has disappeared, click System, then Administration, and select Hardware Drivers.   This will open a dialog showing all the proprietary drivers available for your system, which may include drivers for your video card and other hardware depending on your computer.  Select the driver you wish to install, and click Activate. Enter your password, and then Ubuntu will download and install the driver without any more input.  After installation you may be prompted to reboot your system. Now, you should be able to take full advantage of your hardware, including fancy desktop effects with hardware acceleration. If you ever wish to remove these drivers, simply re-open the drivers dialog as above, select the driver, and click Remove.  Once again, a reboot may be required to finish the process. Conclusion Ubuntu has definitely made it easier to use Linux on your desktop computer, no matter what hardware you have.  If your video card or other hardware require proprietary drivers, it makes them available and simple to install.  And, best of all, all of your drivers stay updated with your software updates, so you can be sure you’re always running the latest.

• View Maps and Get Directions in Google Chrome

  - by Asian Angel

  Every so often we all need to look at a map for reference purposes or to get directions. If you are looking for a great quick reference app then join us as we look at the Mini Google Maps extension for Google Chrome. Mini Google Maps in Action While this may look like a rather basic map extension there is more to it than meets the eye at first glance. Here is the default view when you open Mini Google Maps for the first time. Things that we really liked about this extension were: Three different aerial views available (Map, Satellite, & Terrain) Three different viewing sizes available (and the extension remembers your chosen size) The ability to get directions in combination with a map We decided to try each of the viewing sizes available…here you can see the “Medium Setting”. Notice that the scale stays the same but you get more territory included to view. Then the “Large Setting”…which we infinitely preferred to the others. Once again look at the amount of territory included by default…very nice. Switching over to the “Satellite View”… Followed by the “Terrain View”. For our first example we decided to peek at Vancouver, British Columbia. After zooming out a little bit we had a very nice looking map. For the next test we asked for directions from Vancouver to Toronto. Both the directions and map turned out very well. And just for fun we looked up Paris, France with the “Satellite View”. Conclusion If you find yourself needing to view a map or get directions often then the Mini Google Maps extension will be a very useful tool for you.

• Enable Media Streaming in Windows Home Server to Windows Media Player

  - by Mysticgeek

  One of the cool features of Windows Home Server is the ability to stream photos, music, and video to other computers on your network. Today we take a look at how to enable streaming in WHS to Windows Media Player in Vista and Windows 7. Turn on Media Streaming on WHS To enable Media Streaming from Windows Home Server, open the Windows Home Server Console and click on Settings. Now in the Setting screen select Media Sharing, then in the right column under Media Library Sharing turn on Library Sharing for the folders you want to stream.   If you have a Windows 7 machine on your network make sure media streaming is enabled. You should then see the server under Other Libraries and can start streaming your media collection.   Stream Video to Media Player 11 Now let’s say you want to stream videos to another member of your household who’s using a Vista machine in another room through Windows Media Player 11. Open WMP and click on Library then Media Sharing. Now click the box next to Find media that others are sharing then click Ok. Now you should see the server listed under Library…where in this example it’s geekserver. Since we only enabled Video streaming for this example, we need to click on the category icon and select Video. Now you can scroll through the available videos… And start enjoying your favorite videos streamed from the server through WMP 11 on Vista. Of course you can use this method to stream photos and music as well, you just need to enable what you want to stream from the Home Server Console. You can also stream your media to Windows Media Center and Xbox which we will be covering soon.

• What&rsquo;s new in RadChart for 2010 Q1 (Silverlight / WPF)

  Greetings, RadChart fans! It is with great pleasure that I present this short highlight of our accomplishments for the Q1 release :). Weve worked very hard to make the best silverlight and WPF charting product even better. Here is some of what we did during the past few months.   1) Zooming&Scrolling and the new sampling engine: Without a doubt one of the most important things we did. This new feature allows you to bind your chart to a very large set of data with blazing performance. Dont take my word for it give it a try!   2) New Smart Label Positioning and Spider-like labels feature: This new feature really helps with very busy graphs. You can play with the different settings we offer in this example.     3) Sorting and Filtering. Much like our RadGridview control the chart now allows you to sort and filter your data out of the box with a single line of code!   4) Legend improvements Weve also been paying attention to those of you who wanted a much improved legend. It is now possible to customize the look and feel of legend items and legend position with a single click.     5) Custom palette brushes. You have told us that you want to easily customize all palette colors using a single clean API from both XAML and code behind. The new custom palette brushes API does exactly that.   There are numerous other improvements as well, as much improved themes, performance optimizations and other features that we did. If you want to dig in further check the release notes and changes and backwards compatibility topics.   Feel free to share the pains and gains of working with RadChart. Our team is always open to receiving constructive feedback and beer :-)Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Manage Files Easier With Aero Snap in Windows 7

  - by Mysticgeek

  Before the days of Aero Snap you would need to arrange your Windows in some weird way to see all of your files. Today we show you how to quickly use the Aero Snap feature get it done in few key strokes in Windows 7. You can of course navigate the windows in Explorer to get them so you can see everything side by side, or use a free utility like Cubic Explorer.   Getting Explorer Windows Side by Side The process is actually simple but quite useful when looking for a large amount of data. Right-click the Windows Explorer icon on the taskbar and click Windows Explorer. Our first window opens up and you can certainly drag it over the the right or left side of the screen but the quickest method we’re using is the “Windows Key+Right Arrow” key combo (make sure to hold the Windows key down). Now the Windows is nicely placed on the right side. Next we want to open the other window, simply right-click the Explorer icon again and click Windows Explorer.   Now we have our second window open, and all we need to do this time is use the Windows Key+Left Arrow combination. There we go! Now you should be able to browse your files a lot more simply than relying on the expanding tree method (as much). You can actually use this method to snap a window to all four corners of your screen if you don’t feel like dragging it. Once you play with Aero Snap more you may enjoy it, but if you still despise it, you can disable it too!

• Why do apache2 upgrades remove and not re-install libapache2-mod-php5?

  - by nutznboltz

  We repeatedly see that when an apache2 update arrives and is installed it causes the libapache2-mod-php5 package to be removed and does not subsequently re-install it automatically. We must subsequently re-install the libapache2-mod-php5 manually in order to restore functionality to our web server. Please see the following github gist, it is a contiguous section of our server's dpkg.log showing the November 14, 2011 update to apache2: https://gist.github.com/1368361 it includes 2011-11-14 11:22:18 remove libapache2-mod-php5 5.3.2-1ubuntu4.10 5.3.2-1ubuntu4.10 Is this a known issue? Do other people see this too? I could not find any launchpad bug reports about it. Platform details: $ lsb_release -ds Ubuntu 10.04.3 LTS $ uname -srvm Linux 2.6.38-12-virtual #51~lucid1-Ubuntu SMP Thu Sep 29 20:27:50 UTC 2011 x86_64 $ dpkg -l | awk '/ii.*apache/ {print $2 " " $3 }' apache2 2.2.14-5ubuntu8.7 apache2-mpm-prefork 2.2.14-5ubuntu8.7 apache2-utils 2.2.14-5ubuntu8.7 apache2.2-bin 2.2.14-5ubuntu8.7 apache2.2-common 2.2.14-5ubuntu8.7 libapache2-mod-authnz-external 3.2.4-2+squeeze1build0.10.04.1 libapache2-mod-php5 5.3.2-1ubuntu4.10 Thanks At a high-level the update process looks like: package package_name do action :upgrade case node[:platform] when 'centos', 'redhat', 'scientific' options '--disableplugin=fastestmirror' when 'ubuntu' options '-o Dpkg::Options::="--force-confdef" -o Dpkg::Options::="--force-confold"' end end But at a lower level def install_package(name, version) run_command_with_systems_locale( :command = "apt-get -q -y#{expand_options(@new_resource.options)} install #{name}=#{version}", :environment = { "DEBIAN_FRONTEND" = "noninteractive" } ) end def upgrade_package(name, version) install_package(name, version) end So Chef is using "install" to do "update". This sort of moves the question around to "how does apt-get safe-upgrade" remember to re-install libapache-mod-php5? The exact sequence of packages that triggered this was: apache2 apache2-mpm-prefork apache2-mpm-worker apache2-utils apache2.2-bin apache2.2-common But the code is attempting to run checks to make sure the packages in that list are installed already before attempting to "upgrade" them. case node[:platform] when 'debian', 'centos', 'fedora', 'redhat', 'scientific', 'ubuntu' # first primitive way is to define the updates in the recipe # data bags will be used later %w/ apache2 apache2-mpm-prefork apache2-mpm-worker apache2-utils apache2.2-bin apache2.2-common /.each{ |package_name| Chef::Log.debug("is #{package_name} among local packages available for changes?") next unless node[:packages][:changes].keys.include?(package_name) Chef::Log.debug("is #{package_name} available for upgrade?") next unless node[:packages][:changes][package_name][:action] == 'upgrade' package package_name do action :upgrade case node[:platform] when 'centos', 'redhat', 'scientific' options '--disableplugin=fastestmirror' when 'ubuntu' options '-o Dpkg::Options::="--force-confdef" -o Dpkg::Options::="--force-confold"' end end tag('upgraded') } # after upgrading everything, run yum cache updater if tagged?('upgraded') # Remove old orphaned dependencies and kernel images and kernel headers etc. # Remove cached deb files. case node[:platform] when 'ubuntu' execute 'apt-get -y autoremove' execute 'apt-get clean' # Re-check what updates are available soon. when 'centos', 'fedora', 'redhat', 'scientific' node[:packages][:last_time_we_looked_at_yum] = 0 end untag('upgraded') end end But it's clear that it fails since the dpkg.log has 2011-11-14 11:22:25 install apache2-mpm-worker 2.2.14-5ubuntu8.7 on a system which does not currently have apache2-mpm-worker.

• Skip “Next Links” with the PageZipper Bookmarklet

  - by Asian Angel

  No matter what browser you use sooner or later you will run across a website with an endless number of “next links” used for the sole purpose of generating page views. Now you can simply scroll through those articles without the “next links” using the PageZipper Bookmarklet. The Problem Here is a perfect example of a page view generating article. As you can see our browser is in a non-maximized state and the first part of the article takes up very little room in the browser window. Absolutely horrible… The PageZipper Bookmarklet in Action The bookmarklet is very easy to set up in your browser…simply drag it to your “Bookmarks Toolbar” and you are ready to go. Switching tabs back to the article we never even needed to refresh the page. One nice little click on our new bookmarklet and… It immediately went to work. When you use PageZipper you will see a page count in the upper right corner of the browser window area as shown here. You can see the transition between pages here…nice and smooth. When using the bookmarklet just keep scrolling down as needed to read the entire article. Six pages of reading condensed into one without having to click a single link. Now that is nice! Conclusion If you despise those irritating “next links” then the PageZipper Bookmarklet will be a perfect addition to your favorite browser.

• Display System Information on Your Desktop with Desktop Info

  - by Asian Angel

  Do you like to monitor your system but do not want a complicated app to do it with? If you love simplicity and easy configuration then join us as we look at Desktop Info. Desktop Info in Action Desktop Info comes in a zip file format so you will need to unzip the app, place it into an appropriate “Program Files Folder”, and create a shortcut. Do NOT delete the “Read Me File”…this will be extremely useful to you when you make changes to the “Configuration File”. Once you have everything set up you are ready to start Desktop Info up. This is the default layout and set of listings displayed when you start Desktop Info up for the first time. The font colors will be a mix of colors as seen here and the font size will perhaps be a bit small but those are very easy to change if desired. You can access the “Context Menu” directly over the “information area”…so no need to look for it in the “System Tray”. Notice that you can easily access that important “Read Me File” from here… The full contents of the configuration file (.ini file) are displayed here so that you can see exactly what kind of information can be displayed using the default listings. The first section is “Options”…you will most likely want to increase the font size while you are here. Then “Items”… If you are unhappy with any of the font colors in the “information area” this is where you can make the changes. You can turn information display items on or off here. And finally “Files, Registry, & Event Logs”. Here is our displayed information after a few tweaks in the configuration file. Very nice. Conclusion If you have been looking for a system information app that is simple and easy to set up then you should definitely give Desktop Info a try.

• JavaScript Data Binding Frameworks

  - by dwahlin

  Data binding is where it’s at now days when it comes to building client-centric Web applications. Developers experienced with desktop frameworks like WPF or web frameworks like ASP.NET, Silverlight, or others are used to being able to take model objects containing data and bind them to UI controls quickly and easily. When moving to client-side Web development the data binding story hasn’t been great since neither HTML nor JavaScript natively support data binding. This means that you have to write code to place data in a control and write code to extract it. Although it’s certainly feasible to do it from scratch (many of us have done it this way for years), it’s definitely tedious and not exactly the best solution when it comes to maintenance and re-use. Over the last few years several different script libraries have been released to simply the process of binding data to HTML controls. In fact, the subject of data binding is becoming so popular that it seems like a new script library is being released nearly every week. Many of the libraries provide MVC/MVVM pattern support in client-side JavaScript apps and some even integrate directly with server frameworks like Node.js. Here’s a quick list of a few of the available libraries that support data binding (if you like any others please add a comment and I’ll try to keep the list updated): AngularJS MVC framework for data binding (although closely follows the MVVM pattern). Backbone.js MVC framework with support for models, key/value binding, custom events, and more. Derby Provides a real-time environment that runs in the browser an in Node.js. The library supports data binding and templates. Ember Provides support for templates that automatically update as data changes. JsViews Data binding framework that provides “interactive data-driven views built on top of JsRender templates”. jQXB Expression Binder Lightweight jQuery plugin that supports bi-directional data binding support. KnockoutJS MVVM framework with robust support for data binding. For an excellent look at using KnockoutJS check out John Papa’s course on Pluralsight. Meteor End to end framework that uses Node.js on the server and provides support for data binding on  the client. Simpli5 JavaScript framework that provides support for two-way data binding. WinRT with HTML5/JavaScript If you’re building Windows 8 applications using HTML5 and JavaScript there’s built-in support for data binding in the WinJS library.   I won’t have time to write about each of these frameworks, but in the next post I’m going to talk about my (current) favorite when it comes to client-side JavaScript data binding libraries which is AngularJS. AngularJS provides an extremely clean way – in my opinion - to extend HTML syntax to support data binding while keeping model objects (the objects that hold the data) free from custom framework method calls or other weirdness. While I’m writing up the next post, feel free to visit the AngularJS developer guide if you’d like additional details about the API and want to get started using it.
