• Fill a Flash Drive with Portable Software using Lupo PenSuite

  - by Asian Angel

  A flash drive full of portable software is helpful to have along wherever you go. The Lupo PenSuite lets you choose from three different versions to get the best fit for your everyday needs. Note: If running the full version you will need a 512 MB USB flash drive or larger. Using Lupo PenSuite The one window to watch for during the setup process is where you have the opportunity to add a specific language pack if needed. Outside of that all that you need to do is sit back and wait for the suite to be extracted. Note: Extraction times will vary based on version and extraction location. Here we browsed to our flash drive to extract it to… Once the setup process is complete locate and double click the Lupo_PenSuite.exe file. This one time window will present you the opportunity to start using the suite immediately, or go directly into the options. When the suite is active you will have a new system tray icon that operates as a start menu button. At the bottom you can monitor the remaining room on your flash drive, and use the close button to exit the suite (may display as a power button based on menu theme). A quick look at the set up inside the suite. There is a pre-configured area for organizing and storing your personal files. Prefer a classic style menu? Just select for it in the options (various tab) and enjoy a smaller streamlined look. Note: You can also change the theme for the regular menu and add a user pic. The suite provides access to your portable software and online sites. You get to enjoy the best of both as shown in the following examples. Websites will open using the suite’s portable Firefox install. VLC is ready to play your downloaded videos. The suite also has some very nice photo editing programs added in. Installing Additional Apps If one of your favorite programs is not included in the suite version, it only takes a few minutes to add it in. Go to the Additional Apps webpage, download the app(s), and extract them onto your hard-drive. Note: Link for additional apps webpage provided below. Add the extracted app(s) to the MyApps folder in the suite’s folder hierarchy. Click on ASuite in the suite’s start menu. Drag and drop the portable app’s exe file into the MyApps section in the ASuite window. Your new software’s shortcut should display as shown here. Close this window when finished. Checking the suite’s start menu will show your new software ready to be used. Conclusion If you need a good portable software collection to carry with you on a flash drive then Lupo PenSuite is definitely worth taking a look at. We tested Lupo PenSuite on XP, Vista, and Windows 7 and it works great on all three. Another popular choice is PortableApps and you can check out our Review of that too they are essentially the same thing, each is just packaged differently.

• The enterprise vendor con - connecting SSD's using SATA 2 (3Gbits) thus limiting there performance

  - by tonyrogerson

  When comparing SSD against Hard drive performance it really makes me cross when folk think comparing an array of SSD running on 3GBits/sec to hard drives running on 6GBits/second is somehow valid. In a paper from DELL (http://www.dell.com/downloads/global/products/pvaul/en/PowerEdge-PowerVaultH800-CacheCade-final.pdf) on increasing database performance using the DELL PERC H800 with Solid State Drives they compare four SSD drives connected at 3Gbits/sec against ten 10Krpm drives connected at 6Gbits [Tony slaps forehead while shouting DOH!]. It is true in the case of hard drives it probably doesn’t make much difference 3Gbit or 6Gbit because SAS and SATA are both end to end protocols rather than shared bus architecture like SCSI, so the hard drive doesn’t share bandwidth and probably can’t get near the 600MiBytes/second throughput that 6Gbit gives unless you are doing contiguous reads, in my own tests on a single 15Krpm SAS disk using IOMeter (8 worker threads, queue depth of 16 with a stripe size of 64KiB, an 8KiB transfer size on a drive formatted with an allocation size of 8KiB for a 100% sequential read test) I only get 347MiBytes per second sustained throughput at an average latency of 2.87ms per IO equating to 44.5K IOps, ok, if that was 3GBits it would be less – around 280MiBytes per second, oh, but wait a minute [...fingers tap desk] You’ll struggle to find in the commodity space an SSD that doesn’t have the SATA 3 (6GBits) interface, SSD’s are fast not only low latency and high IOps but they also offer a very large sustained transfer rate, consider the OCZ Agility 3 it so happens that in my masters dissertation I did the same test but on a difference box, I got 374MiBytes per second at an average latency of 2.67ms per IO equating to 47.9K IOps – cost of an 240GB Agility 3 is £174.24 (http://www.scan.co.uk/products/240gb-ocz-agility-3-ssd-25-sata-6gb-s-sandforce-2281-read-525mb-s-write-500mb-s-85k-iops), but that same drive set in a box connected with SATA 2 (3Gbits) would only yield around 280MiBytes per second thus losing almost 100MiBytes per second throughput and a ton of IOps too. So why the hell are “enterprise” vendors still only connecting SSD’s at 3GBits? Well, my conspiracy states that they have no interest in you moving to SSD because they’ll lose so much money, the argument that they use SATA 2 doesn’t wash, SATA 3 has been out for some time now and all the commodity stuff you buy uses it now. Consider the cost, not in terms of price per GB but price per IOps, SSD absolutely thrash Hard Drives on that, it was true that the opposite was also true that Hard Drives thrashed SSD’s on price per GB, but is that true now, I’m not so sure – a 300GByte 2.5” 15Krpm SAS drive costs £329.76 ex VAT (http://www.scan.co.uk/products/300gb-seagate-st9300653ss-savvio-15k3-25-hdd-sas-6gb-s-15000rpm-64mb-cache-27ms) which equates to £1.09 per GB compared to a 480GB OCZ Agility 3 costing £422.10 ex VAT (http://www.scan.co.uk/products/480gb-ocz-agility-3-ssd-25-sata-6gb-s-sandforce-2281-read-525mb-s-write-410mb-s-30k-iops) which equates to £0.88 per GB. Ok, I compared an “enterprise” hard drive with a “commodity” SSD, ok, so things get a little more complicated here, most “enterprise” SSD’s are SLC and most commodity are MLC, SLC gives more performance and wear, I’ll talk about that another day. For now though, don’t get sucked in by vendor marketing, SATA 2 (3Gbit) just doesn’t cut it, SSD need 6Gbit to breath and even that SSD’s are pushing. Alas, SSD’s are connected using SATA so all the controllers I’ve seen thus far from HP and DELL only do SATA 2 – deliberate? Well, I’ll let you decide on that one.

• Using Live Data in Database Development Work

  - by Phil Factor

  Guest Editorial for Simple-Talk Newsletter... in which Phil Factor reacts with some exasperation when coming across a report that a majority of companies were still using financial and personal data for both developing and testing database applications. If you routinely test your development work using real production data that contains personal or financial information, you are probably being irresponsible, and at worst, risking a heavy financial penalty for your company. Surprisingly, over 80% of financial companies still do this. Plenty of data breaches and fraud have happened from the use of real data for testing, and a data breach is a nightmare for any organisation that suffers one. The cost of each data breach averages out at around $7.2 million in the US in notification, escalation, credit monitoring, fines, litigation, legal costs, and lost business due to customer churn, £1.9 million in the UK. 70% of data breaches are done from within the organisation. Real data can be exploited in a number of ways for malicious or criminal purposes. It isn't just the obvious use of items such as name and address, date of birth, social security number, and credit card and bank account numbers: Data can be exploited in many subtle ways, so there are excellent reasons to ensure that a high priority is given to the detection and prevention of any data breaches. You'll never successfully guess all the ways that real data can be exploited maliciously, or the ease with which it can be accessed. It would be silly to argue that developers never need access to a copy of the database containing live data. Developers sometimes need to track a bug that can only be replicated on the data from the live database. However, it has to be done in a very restrictive harness. The law makes no distinction between development and production databases when a data breach occurs, so the data has to be held with all appropriate security measures in place. In Europe, the use of personal data for testing requires the explicit consent of the people whose data is being held. There are federal standards such as GLBA, PCI DSS and HIPAA, and most US States have privacy legislation. The task of ensuring compliance and tight security in such circumstances is an expensive and time-consuming overhead. The developer is likely to suffer investigation if a data breach occurs, even if the company manages to stay in business. Ironically, the use of copies of live data isn't usually the most effective way to develop or test your data. Data is usually time-specific and isn't usually current by the time it is used for testing, Existing data doesn't help much for new functionality, and every time the data is refreshed from production, any test data is likely to be overwritten. Also, it is not always going to test all the 'edge' conditions that are likely to flush out bugs. You still have the task of simulating the dynamics of actual usage of the database, and here you have no alternative to creating 'spoofed' data. Because of the complexities of relational data, It used to be that there was no realistic alternative to developing and testing with live data. However, this is no longer the case. Real data can be obfuscated, or it can be created entirely from scratch. The latter process used to be impractical, now that there are plenty of third-party tools to choose from. The process of obfuscation isn't risk free. The process must access the live data, and the success of the obfuscation process has to be carefully monitored. Database data security isn't an exciting topic to you or I, but to a hacker it can be an all-consuming obsession, especially if there is financial or political gain involved. This is not the sort of adversary one would wish for and it is far better to accept, and work with, security restrictions that exist for using live data in database development work, especially when the tools exist to create large realistic database test data that can be better for several aspects of testing.

• Converting from mp4 to Xvid avi using avconv?

  - by Ricardo Gladwell

  I normally use avidemux to convert mp4s to Xvid AVI for my Philips Streamium SLM5500. Normally I select MPEG-4 ASP (Xvid) at Two Pass with an average bitrate f 1500kb/s for video and AC3 (lav) audio and it converts correctly. However, I'm trying to using avconv so I can automate the process with a script, but when I do this the video stutters and stops playing part way through. I have a suspicion its something to do with a faulty audio conversion. The commands I'm using are as follows: avconv -y -i video.mp4 -pass 1 -vtag xvid -c:a ac3 -b:a 128k -b:v 1500k -f avi /dev/null avconv -y -i video.mp4 -pass 2 -vtag xvid -c:a ac3 -b:a 128k -b:v 1500k -f avi video.avi There is a bewildering array of arguments for avconv. Is there something I'm doing wrong? Is there a way I can script avidemux from a headless server?

• Child transforms problem when loading 3DS models using assimp

  - by MhdSyrwan

  I'm trying to load a textured 3d model into my scene using assimp model loader. The problem is that child meshes are not situated correctly (they don't have the correct transformations). In brief: all the mTansform matrices are identity matrices, why would that be? I'm using this code to render the model: void recursive_render (const struct aiScene *sc, const struct aiNode* nd, float scale) { unsigned int i; unsigned int n=0, t; aiMatrix4x4 m = nd->mTransformation; m.Scaling(aiVector3D(scale, scale, scale), m); // update transform m.Transpose(); glPushMatrix(); glMultMatrixf((float*)&m); // draw all meshes assigned to this node for (; n < nd->mNumMeshes; ++n) { const struct aiMesh* mesh = scene->mMeshes[nd->mMeshes[n]]; apply_material(sc->mMaterials[mesh->mMaterialIndex]); if (mesh->HasBones()){ printf("model has bones"); abort(); } if(mesh->mNormals == NULL) { glDisable(GL_LIGHTING); } else { glEnable(GL_LIGHTING); } if(mesh->mColors[0] != NULL) { glEnable(GL_COLOR_MATERIAL); } else { glDisable(GL_COLOR_MATERIAL); } for (t = 0; t < mesh->mNumFaces; ++t) { const struct aiFace* face = &mesh->mFaces[t]; GLenum face_mode; switch(face->mNumIndices) { case 1: face_mode = GL_POINTS; break; case 2: face_mode = GL_LINES; break; case 3: face_mode = GL_TRIANGLES; break; default: face_mode = GL_POLYGON; break; } glBegin(face_mode); for(i = 0; i < face->mNumIndices; i++)// go through all vertices in face { int vertexIndex = face->mIndices[i];// get group index for current index if(mesh->mColors[0] != NULL) Color4f(&mesh->mColors[0][vertexIndex]); if(mesh->mNormals != NULL) if(mesh->HasTextureCoords(0))//HasTextureCoords(texture_coordinates_set) { glTexCoord2f(mesh->mTextureCoords[0][vertexIndex].x, 1 - mesh->mTextureCoords[0][vertexIndex].y); //mTextureCoords[channel][vertex] } glNormal3fv(&mesh->mNormals[vertexIndex].x); glVertex3fv(&mesh->mVertices[vertexIndex].x); } glEnd(); } } // draw all children for (n = 0; n < nd->mNumChildren; ++n) { recursive_render(sc, nd->mChildren[n], scale); } glPopMatrix(); } What's the problem in my code ? I've added some code to abort the program if there's any bone in the meshes, but the program doesn't abort, this means : no bones, is that normal? if (mesh->HasBones()){ printf("model has bones"); abort(); } Note: I am using openGL & SFML & assimp

• Procedual level generation for a platformer game (tilebased) using player physics

  - by Notbad

  I have been searching for information about how to build a 2d world generator (tilebased) for a platformer game I am developing. The levels should look like dungeons with a ceiling and a floor and they will have a high probability of being just made of horizontal rooms but sometimes they can have exits to a top/down room. Here is an example of what I would like to achieve. I'm refering only to the caves part. I know level design won't be that great when generated but I think it is possible to have something good enough for people to enjoy the procedural maps (Note: Supermetrod Spoiler!): http://www.snesmaps.com/maps/SuperMetroid/SuperMetroidMapNorfair.html Well, after spending some time thinking about this I have some ideas to create the maps that I would like to share with you: 1) I have read about celular automatas and I would like to use them to carve the rooms but instead of carving just a tile at once I would like to carve full columns of tiles. Of course this carving system will have some restrictions like how many tiles must be left for the roof and the ceiling, etc... This way I could get much cleaner rooms than using the ussual automata. 2) I want some branching into the rooms. It will have little probability to happen but I definitely want it. Thinking about carving I came to the conclusion that I could be using some sort of path creation algorithm that the carving system would follow to create a path in the rooms. This could be more noticiable if we make the carving system to carve columns with the height of a corridor or with the height of a wide room (this will be added to the system as a param). This way at some point I could spawn a new automa beside the main one to create braches. This new automata should play side by side with the first one to create dead ends, islands (both paths created by the automatas meet at some point or lead to the same room. It would be too long to explain here all the tests I have done, etc... just will try to summarize the problems to see if anyone could bring some light to solve them (I don't mind sharing my successes but I think they aren't too relevant): 1) Zone reachability: How can I make sure that the player will be able to reach all zones I created (mainly when branches happen or vertical rooms are created). When branches are created I have to make sure that there will be a way to get onto the new created branch. I mean a bifurcation that the player could follow. Player will follow the main path or jump to a platform to get onto the other way). On the other hand if an island is created by the meeting of both branches I need to make sure the player will be able to get onto the island too. 2) When a branch is created and corridors are generated for each branch how can I make then both merge or repel to create an island or just make them separated corridors. 3) When I create a branch and an island is created becasue both corridors merge at somepoint or they lead to the same room, is there any way to detect this and randomize where to create the needed platforms to get onto the created isle? This platforms could be created at the start of the island or at the end. I guess part of the problem could be solved using some sort of graph following the created paths but I'm a bit lost in this sea of precedural content creation :). On the other hand I don't expect a solution to the problem but some information to get me moving forward again. Thanks in advance.

• Application using JOGL stays in Limbo when closing

  - by Roy T.

  I'm writing a game using Java and OpenGL using the JOGL bindings. I noticed that my game doesn't terminate properly when closing the window even though I've set the closing operation of the JFrame to EXIT_ON_CLOSE. I couldn't track down where the problem was so I've made a small reproduction case. Note that on some computers the program terminates normally when closing the window but on other computers (notably my own) something in the JVM keeps lingering, this causes the JFrame to never be disposed and the application to never exit. I haven't found something in common between the computers that had difficulty terminating. All computers had Windows 7, Java 7 and the same version of JOGL and some terminated normally while others had this problem. The test case is as follows: public class App extends JFrame implements GLEventListener { private GLCanvas canvas; @Override public void display(GLAutoDrawable drawable) { GL3 gl = drawable.getGL().getGL3(); gl.glClearColor(0.0f, 0.0f, 0.0f, 0.0f); gl.glClear(GL3.GL_COLOR_BUFFER_BIT); gl.glFlush(); } // The overrides for dispose (the OpenGL one), init and reshape are empty public App(String title, boolean full_screen, int width, int height) { //snipped setting the width and height of the JFRAME GLProfile profile = GLProfile.get(GLProfile.GL3); GLCapabilities capabilities = new GLCapabilities(profile); canvas = new GLCanvas(capabilities); canvas.addGLEventListener(this); canvas.setSize(getWidth(), getHeight()); add(canvas); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); //!!! setVisible(true); } @Override public void dispose() { System.out.println("HELP"); // } public static void main( String[] args ) { new App("gltut 01", false, 1280, 720); } } As you can see this doesn't do much more than adding a GLCanvas to the frame and registering the main class as the GLEventListener. So what keeps lingering? I'm not sure. I've made some screenshots. The application running normally. The application after the JFrame is closed, note that the JVM still hasn't exited or printed a return code. The application after it was force closed. Note the return code -1, so it wasnt just the JVM standing by or something the application really hadn't exited yet. So what is keeping the application in Limbo? Might it be the circular reference between the GLCanvas and the JFrame? I thought the GC could figure that out. If so how should I deal with that when I want to exit? Is there any other clean-up required when using JOGL? I've tried searching but it doesn't seem to be necessary. Edit, to clarify: there are 2 dispose functions dispose(GLAutoDrawable arg) which is a member of GLEventListener and dispose() which is a member of JFrame. The first one is called correctly (but I wouldn't know what to there, destroying the GLAutoDrawable or the GLCanvas gives an infinite exception loop) the second one is never called.

• Why do I have two different DNS suffix lists?

  - by Rob Kennedy

  My Windows XP laptop has two different DNS suffix lists. The first is the one I see by selecting the Properties dialog of any of my network connections, selecting Internet Protocol Properties Advanced DNS tab, and looking at the list under the "Append these DNS suffixes (in order)" option. The second list is the one shown under "DNS Suffix Search List" when I run ipconfig /all. As far as I can tell, only the second list ever gets used to resolve unqualified host names. Why are there two different lists? How do I configure the second list? Or how can I make my computer use the first list?

• Persisting model state in ASP.NET MVC using Serialize HTMLHelper

  - by shiju

  ASP.NET MVC 2 futures assembly provides a HTML helper method Serialize that can be use for persisting your model object. The Serialize  helper method will serialize the model object and will persist it in a hidden field in the HTML form. The Serialize  helper is very useful when situations like you are making multi-step wizard where a single model class is using for all steps in the wizard. For each step you want to retain the model object's whole state.The below is serializing our model object. The model object should be a Serializable class in order to work with Serialize helper method. <% using (Html.BeginForm("Register","User")) {%><%= Html.Serialize("User",Model) %> This will generate hidden field with name "user" and the value will the serialized format of our model object.In the controller action, you can place the DeserializeAttribute in the action method parameter. [HttpPost]               public ActionResult Register([DeserializeAttribute] User user, FormCollection userForm) {     TryUpdateModel(user, userForm.ToValueProvider());     //To Do } In the above action method you will get the same model object that you serialized in your view template. We are updating the User model object with the form field values.

• XNA - Strange Texture Rendering Issue Using XNA BasicEffect

  - by Spencer Marr

  I have been reading and working through Riemers 3D XNA tutorials to expand my knowledge of XNA from 2D into 3D. Unfortunately I am having rendering issues that I am unable to solve and I need a point in the right direction. I am not expecting the Models to look identical to Blender but there is some serious discoloring from the texture files once rendering through XNA. The Character model is using completely incorrect colors (Red where Grey should be) and the Cube is rendering a strange pattern where a flat color should be drawn. My sampling mode is set to PointClamp. The Character model that I created has a 32 by 32 pixel texture that has been UV mapped to the model in blender. The model was then exported to .FBX. For the Cube Model a 64 by 64 pixel texture is used. foreach (ModelMesh mesh in samuraiModel.Meshes) { foreach (BasicEffect effect in mesh.Effects) { effect.Projection = Projection; effect.View = View; effect.World = World; } mesh.Draw(); } Does this look like it is caused by a mistake I made while UV Mapping or Creating Materials in Blender? Is this a problem with using the default XNA BasicEffect? Or something completely different that i have not considered? Thank You!

The model object should be a Serializable class in order to work with Serialize helper method. <% using (Html.BeginForm("Register","User")) {%><%= Html.Serialize("User",Model) %> This will generate hidden field with name "user" and the value will the serialized format of our model object.In the controller action, you can place the DeserializeAttribute in the action method parameter. [HttpPost]               public ActionResult Register([DeserializeAttribute] User user, FormCollection userForm) {     TryUpdateModel(user, userForm.ToValueProvider());     //To Do } In the above action method you will get the same model object that you serialized in your view template. We are updating the User model object with the form field values.

• Fixing up Visual Studio&rsquo;s gitignore , using IFix

  - by terje

  Originally posted on: http://geekswithblogs.net/terje/archive/2014/06/13/fixing-up-visual-studiorsquos-gitignore--using-ifix.aspxDownload tool Is there anything wrong with the built-in Visual Studio gitignore ???? Yes, there is !  First, some background: When you set up a git repo, it should be small and not contain anything not really needed.  One thing you should not have in your git repo is binary files. These binary files may come from two sources, one is the output files, in the bin and obj folders.  If you have a  gitignore file present, which you should always have (!!), these folders are excluded by the standard included file (the one included when you choose Team Explorer/Settings/GitIgnore – Add.) The other source are the packages folder coming from your NuGet setup.  You do use NuGet, right ?  Of course you do !  But, that gitignore file doesn’t have any exclude clause for those folders.  You have to add that manually.  (It will very probably be included in some upcoming update or release).  This is one thing that is missing from the built-in gitignore. To add those few lines is a no-brainer, you just include this: # NuGet Packages packages/* *.nupkg # Enable "build/" folder in the NuGet Packages folder since # NuGet packages use it for MSBuild targets. # This line needs to be after the ignore of the build folder # (and the packages folder if the line above has been uncommented) !packages/build/ Now, if you are like me, and you probably are, you add git repo’s faster than you can code, and you end up with a bunch of repo’s, and then start to wonder: Did I fix up those gitignore files, or did I forget it? The next thing you learn, for example by reading this blog post, is that the “standard” latest Visual Studio gitignore file exist at https://github.com/github/gitignore, and you locate it under the file name VisualStudio.gitignore.  Here you will find all the new stuff, for example, the exclusion of the roslyn ide folders was commited on May 24th.  So, you think, all is well, Visual Studio will use this file …..     I am very sorry, it won’t. Visual Studio comes with a gitignore file that is baked into the release, and that is by this time “very old”.  The one at github is the latest.  The included gitignore miss the exclusion of the nuget packages folder, it also miss a lot of new stuff, like the Roslyn stuff. So, how do you fix this ?  … note .. while we wait for the next version… You can manually update it for every single repo you create, which works, but it does get boring after a few times, doesn’t it ? IFix Enter IFix ,  install it from here. IFix is a command line utility (and the installer adds it to the system path, you might need to reboot), and one of the commands is gitignore If you run it from a directory, it will check and optionally fix all gitignores in all git repo’s in that folder or below.  So, start up by running it from your C:/<user>/source/repos folder. To run it in check mode – which will not change anything, just do a check: IFix  gitignore --check What it will do is to check if the gitignore file is present, and if it is, check if the packages folder has been excluded.  If you want to see those that are ok, add the --verbose command too.  The result may look like this: Fixing missing packages Let us fix a single repo by adding the missing packages structure,  using IFix --fix We first check, then fix, then check again to verify that the gitignore is correct, and that the “packages/” part has been added. If we open up the .gitignore, we see that the block shown below has been added to the end of the .gitignore file.   Comparing and fixing with latest standard Visual Studio gitignore (from github) Now, this tells you if you miss the nuget packages folder, but what about the latest gitignore from github ? You can check for this too, just add the option –merge (why this is named so will be clear later down) So, IFix gitignore --check –merge The result may come out like this  (sorry no colors, not got that far yet here): As you can see, one repo has the latest gitignore (test1), the others are missing either 57 or 150 lines.  IFix has three ways to fix this: --add --merge --replace The options work as follows: Add:  Used to add standard gitignore in the cases where a .gitignore file is missing, and only that, that means it won’t touch other existing gitignores. Merge: Used to merge in the missing lines from the standard into the gitignore file.  If gitignore file is missing, the whole standard will be added. Replace: Used to force a complete replacement of the existing gitignore with the standard one. The Add and Replace options can be used without Fix, which means they will actually do the action. If you combine with --check it will otherwise not touch any files, just do a verification.  So a Merge Check will  tell you if there is any difference between the local gitignore and the standard gitignore, a Compare in effect. When you do a Fix Merge it will combine the local gitignore with the standard, and add what is missing to the end of the local gitignore. It may mean some things may be doubled up if they are spelled a bit differently.  You might also see some extra comments added, but they do no harm. Init new repo with standard gitignore One cool thing is that with a new repo, or a repo that is missing its gitignore, you can grab the latest standard just by using either the Add or the Replace command, both will in effect do the same in this case. So, IFix gitignore --add will add it in, as in the complete example below, where we set up a new git repo and add in the latest standard gitignore: Notes The project is open sourced at github, and you can also report issues there.

• SQL SERVER – Solution to Puzzle – Simulate LEAD() and LAG() without Using SQL Server 2012 Analytic Function

  - by pinaldave

  Earlier I wrote a series on SQL Server Analytic Functions of SQL Server 2012. During the series to keep the learning maximum and having fun, we had few puzzles. One of the puzzle was simulating LEAD() and LAG() without using SQL Server 2012 Analytic Function. Please read the puzzle here first before reading the solution : Write T-SQL Self Join Without Using LEAD and LAG. When I was originally wrote the puzzle I had done small blunder and the question was a bit confusing which I corrected later on but wrote a follow up blog post on over here where I describe the give-away. Quick Recap: Generate following results without using SQL Server 2012 analytic functions. I had received so many valid answers. Some answers were similar to other and some were very innovative. Some answers were very adaptive and some did not work when I changed where condition. After selecting all the valid answer, I put them in table and ran RANDOM function on the same and selected winners. Here are the valid answers.

• Twitter Feeds in Umbraco using XSLT

  - by Vizioz Limited

  There are currently two packages tagged on the Umbraco forum that can be used to add a twitter feed to your website. I was playing around with "Twitter for Umbraco" by Warren Buckley and noticed a bug in the way it converted twitter @names to links, so I thought I would try and solve this using XSLT.It may also be useful for those of you using Darren Ferguson's "Feed Cache" package as the demo on Darren's site does not add links to the tweets.To use this XSLT you simple call the XSLT Template passing in your Twitter message:<xsl:call-template name="formaturl"> <xsl:with-param name="url" select="text"/></xsl:call-template>Then add the XSLT template to your XSLT macro (outside of the main template)<xsl:template name="formaturl"> <xsl:param name="twitterfeed"/> <xsl:variable name="transform-http" select="Exslt.ExsltRegularExpressions:replace($twitterfeed, '(http\:\/\/\S+)',ig,'<a href="$1">$1</a>')"/> <xsl:variable name="transform-https" select="Exslt.ExsltRegularExpressions:replace($transform-http, '(HTTps\:\/\/\S+)',ig,'<a href="$1">$1</a>')"/> <xsl:variable name="transform-AT" select="Exslt.ExsltRegularExpressions:replace($transform-https, '(^|\s)@(\w+)',ig,' <a href="http://www.twitter.com/$2">@$2</a>')"/> <xsl:variable name="transform-HASH" select="Exslt.ExsltRegularExpressions:replace($transform-AT, '(^|\s)#(\w+)',ig,' <a href="http://www.twitter.com/search?q=$2">#$2</a>')"/> <xsl:value-of select="$transform-HASH" disable-output-escaping="yes"/> </xsl:template>You should find that this now replaces all the @names, #names and URL's with links!

• Using Completed User Stories to Estimate Future User Stories

  - by David Kaczynski

  In Scrum/Agile, the complexity of a user story can be estimated in story points. After completing some user stories, a programmer or team of programmers can use those experiences to better estimate how much time it might take to complete a future user story. Is there a methodology for breaking down the complexity of user stories into quantifiable or quantifiable attributes? For example, User Story X requires a rich, new view in the GUI, but User Story X can perform most of its functionality using existing business logic on the server. On a scale of 1 to 10, User Story X has a complexity of 7 on the client and a complexity of 2 on the server. After User Story X is completed, someone asks how long would it take to complete User Story Y, which has a complexity of 3 on the client and 6 on the server. Looking at how long it took to complete User Story X, we can make an educated estimate on how long it might take to complete User Story Y. I can imagine some other details: The complexity of one attribute (such as complexity of client) could have sub-attributes, such as number of steps in a sequence, function points, etc. Several other attributes that could be considered as well, such as the programmer's familiarity with the system or the number of components/interfaces involved These attributes could be accumulated into some sort of user story checklist. To reiterate: is there an existing methodology for decomposing the complexity of a user story into complexity of attributes/sub-attributes, or is using completed user stories as indicators in estimating future user stories more of an informal process?

• Creating block devices for openstack deployment using MAAS and juju (nova-volume deployment)

  - by Tom Van Hoof

  Hi, I'm currently trying to get a openstack deployment working by using MAAS with 9 nodes and juju. To do this I found this guide, working with ubuntu 12.04 LTS https://help.ubuntu.com/community/UbuntuCloudInfrastructure and followed it as good as I can. After a vigorous amount of trial and error I finally got to the point where I'm supposed to deploy nova-volume using the "custom" config file. However when my node is started and shows up as running in the "juju status" report the service reports the installation failed. I'm trying to install with juju jitsu by the way. I think it has something to do with the following statement in the openstack.cfg file : nova-volume: # This must be a free block device that is writable on the nova-volume host. block-device: "xvdb" overwrite: "true" I did some research and found that (at least I think) this refers to a Xen Virtual Drive/device, and because the device is not present on the node it's being deployed to, the installation fails. What I don't understand is how I am supposed to have such a block device available on a machine which was completely managed by MAAS. Does anyone here have any experience with this and knows of a way to solve this, or am I missing something big here. Some kind of missing link between the MAAS and a separate XEN host ? My MAAS server is ubuntu 12.04LTS Server. All help is welcome. Kind regards, Tom

• Accessing Server-Side Data from Client Script: Using Ajax Web Services, Script References, and jQuery

  Today's websites commonly exchange information between the browser and the web server using Ajax techniques. In a nutshell, the browser executes JavaScript code typically in response to the page loading or some user action. This JavaScript makes an asynchronous HTTP request to the server. The server processes this request and, perhaps, returns data that the browser can then seamlessly integrate into the web page. Typically, the information exchanged between the browser and server is serialized into JSON, an open, text-based serialization format that is both human-readable and platform independent. Adding such targeted, lightweight Ajax capabilities to your ASP.NET website requires two steps: first, you must create some mechanism on the server that accepts requests from client-side script and returns a JSON payload in response; second, you need to write JavaScript in your ASP.NET page to make an HTTP request to this service you created and to work with the returned results. This article series examines a variety of techniques for implementing such scenarios. In Part 1 we used an ASP.NET page and the JavaScriptSerializer class to create a server-side service. This service was called from the browser using the free, open-source jQuery JavaScript library. This article continues our examination of techniques for implementing lightweight Ajax scenarios in an ASP.NET website. Specifically, it examines how to create ASP.NET Ajax Web Services on the server-side and how to use both the ASP.NET Ajax Library and jQuery to consume them from the client-side.

• Building a Store Locator ASP.NET Application Using Google Maps API (Part 3)

  Over the past two weeks I've showed how to build a store locator application using ASP.NET and the free Google Maps API and Google's geocoding service. Part 1 looked at creating the database to record the store locations. This database contains a table named Stores with columns capturing each store's address and latitude and longitude coordinates. Part 1 also showed how to use Google's geocoding service to translate a user-entered address into latitude and longitude coordinates, which could then be used to retrieve and display those stores within (roughly) a 15 mile area. At the end of Part 1, the results page listed the nearby stores in a grid. In Part 2 we used the Google Maps API to add an interactive map to the search results page, with each nearby store displayed on the map as a marker. The map added in Part 2 certainly improves the search results page, but the way the nearby stores are displayed on the map leaves a bit to be desired. For starters, each nearby store is displayed on the map using the same marker icon, namely a red pushpin. This makes it difficult to match up the nearby stores listed in the grid with those displayed on the map. Hovering the mouse over a marker on the map displays the store number in a tooltip, but ideally a user could click a marker to see more detailed information about the store, such as its address, phone number, a photo of the storefront, and so forth. This third and final installment shows how to enhance the map created in Part 2. Specifically, we'll see how to customize the marker icons displayed in the map to make it easier to identify which marker corresponds to which nearby store location. We'll also look at adding rich popup windows to each marker, which includes detailed store information and can be updated further to include pictures and other HTML content. Read on to learn more!

• Using Fiddler with BizTalk's HTTP Adapter

  - by Christopher House

  I'm working on an orchestration that's retrieving some data from a Java servlet.  The servlet takes a parameter string via HTTP post and returns POX (plain old XML, no SOAP here).  I was having trouble getting a valid response from the servlet when I was sending some test messages and wanted to see what my messages were looking like as they went across the wire.  Normally I was using WCF, I'd setup message logging, but since that's obviously not an option with the HTTP adapter, my thoughts turned to Fiddler.  A quick Google search turned up some promising results.  The posts I read all referred to using Fiddler with the SOAP adapter, but I thoght I could apply the same ideas to the HTTP adapter.  This led me to try setting the following context properties: HttpRequestMessage(HTTP.UseProxy) = true; HttpRequestMessage(HTTP.ProxyName) = "127.0.0.1"; HttpRequestMessage(HTTP.ProxyPort) = 8888; I rebuilt my orch, gac'd it, bounced my host and tried submitting a test message.  Fiddler was running but I didn't see any traffic show up.  I tried fully undeploying/redeploying my application and still, no traffic in Fiddler.  I was starting to think that BizTalk was ignoring the proxy settings.  To confirm this, I closed Fiddler and submitted a test message.  Sure enough, the orch ran to completion, proving that BizTalk was ignoring the proxy settings. I went back to my orch to see if there could be any other context proprties I needed to set.  I saw one that looked promising:  HTTP.UseHandlerProxySettings.  I set this to false, rebuilt my orch and this time when I submitted, I got an error message, which made sense, I didn't have Fiddler running.  I started up Fiddler, submitted another message and there it was, my HTTP traffic, just as I hoped.  And, I was quickly able to figure out what the problem was...I had forgotten to set HTTP.ContentType to application/x-www-form-urlencoded.

• ASP.NET MVC: Using jQuery context menu with tables

  - by DigiMortal

  I needed to add context menus to some tables of my intranet application. After trying some components I found one that does everything I need and has no overhead. In this posting I will show you how to use jQuery context menu plug-in and how to attach it to tables. I found context menu plug-in by Chris Domigan and it was very easy to integrate to my application (when comparing some other plug-ins that work only on demo pages and in simple scenarios). Thanks, Chris, for great work! Now let’s use this context menu plug-in with table. Before we go on let’s see what we are trying to achieve. The following screenshot fragment shows simple context menu that we want to attach to our table. And when we click some menu option then something should happen too. :) Installing context menu plug-in Download plug-in (if download link is broken then open demo page and I think you know how to get plug-in from there). Copy jquery.contextmenu.js to your scripts folder. Include it in your masterpage or in the page where you plan to use context menus. Make sure plug-in is included correctly (use Firebug or some other tool you like). Save the page. Defining context menu Now let’s define context menu. Here is fragment on context menu definition from my code. <div class="contextMenu" id="myMenu1">     <ul>     <li id="email"><img src="/img/e-mail.png" />E-mail</li>     <li id="homepage"><img src="/img/homepage.png" />Homepage</li>     </ul> </div> div with id myMenu1 is container of context menu. Unordered list inside container defines items in context menu – simple and elegant! Adding context menu to table I have table with persons. It is simple HTML. I omitted commands column from this and the next table to keep them simple and more easily readable. <table>   <tr>     <th>Name</th>     <th>Short</th>     <th>Address</th>     <th>Mobile</th>     <th>E-mail</th>   </tr>   <% foreach(var person in Model.Results) { %>   <tr>     <td><%=person.FullName %></td>     <td><%=person.ShortName %></td>     <td><%=person.FullAddress %></td>     <td><%=person.Mobile %></td>     <td><%=person.Email %></td>   </tr>   <% } %> </table> To get context menu linked to table rows first cells we need to specify class for cells and ID. We need ID because we have to know later which ID has the row on which user selected something from context menu. <table>   <tr>     <th>Name</th>     <th>Short</th>     <th>Address</th>     <th>Mobile</th>     <th>E-mail</th>   </tr>   <% foreach(var person in Model.Results) { %>   <tr>     <td class="showContext" id="<%= person.Id %>"><%=person.FullName %></td>     <td><%=person.ShortName %></td>     <td><%=person.FullAddress %></td>     <td><%=person.Mobile %></td>     <td><%=person.Email %></td>   </tr>   <% } %> </table> Now we have only one thing to do – we have to write some code that attaches context menu to table cells. Catching context menu events Now we will make everything work. Relax, it is only couple of lines of code, thank to jQuery. <script type="text/javascript">   $(document).ready(function () {     $('td.showContext').contextMenu('myMenu1', {         bindings: {         'email': function (t) {           document.location.href = '/contact/sendmail/' + t.id;         },         'homepage': function (t) {           document.location.href = '/contact/homepage/' + t.id;         }       }     });   }); </script> I think that first lines doesn’t need any comments. Take a look at bindings. We gave ID to table cells because it is carried also to bound events. We can use also more complex ID-s if we have more than one table with context menus on our form. Now we are done. Save all files, compile solution, run it and try out how context menu works. Conclusion We saw than using jQuery with context menu component allows us easily create powerful context menus for our user interfaces. Context menu was very easy to define. We were also able to attach context menu to table and use ID of current row entity also in events of context menu. To achieve this we needed only some minor modifications in view and couple of lines of JavaScript.

• Retrieve the content of Microsoft Word document using OpenXml and C#

  - by ybbest

  One of the tasks involves me to retrieve the contents of Microsoft Word document (word2007 above). I try to search for some resources online with not much luck; most of the examples are for writing contents to word document using OpenXml. I decide to blog this as my reference and hopefully people who read this post will find it useful as well. To retrieve the contents of Microsoft Word document using XML is extremely simple. 1. Firstly, you need to download and install the Open XML SDK 2.0 for Microsoft Office. (Download link) 2. Create a Console application then add the DocumentFormat.OpenXml.dll and WindowsBase.dll to the project, you can find these dlls in the .NET tab of the Add Reference window. 3. Write the following code to grab the contents from the word document and display it on the console window. You can download the complete source code here.

• Etch a Circuit Board using a Simple Homemade Mixture

  - by ETC

  If you’ve been dabbling in DIY electronics projects but you’re not so excited about keeping strong acids around to etch your circuit boards, this simple DIY recipe uses common household chemicals in lieu of strong acid. Electronics hobbyist Stephen Hobley wanted to see if he could create an etching solution that wasn’t as dangerous and noxious smelling at traditional muriatic acid solutions. By combining regular white vinegar, hydrogen peroxide, and table salt, he created a homemade etching solution from ingredients safe enough to store in your pantry. The only downside to his recipe is that, compared to traditional etching solutions, the process takes a little bit longer so you’ll have to leave your board in the solution longer. Not a bad trade off for the ability to skip using any oops-I-burned-my-skin-off acids. Check out the process in the video below: Hit up the link below for more information and and interesting explanation of the chemical process (he talks about not quite understanding it in the video but two chemists write in and give him the full run down).
