  • How can I justify software testing to management?

    - by Nate
    I work for a small company (less than 200 employees) whose software group only makes up a small part of our staff (4 employees, occasionally with a few contractors). The four of us have been making strides in transitioning to better practices, and one of the next logical steps is to improve our testing. As anyone who has done any meaningful tests knows, testing takes a lot of time - and at my company, it takes too much time to justify to management, so we generally do what little we do on the sly. I don't think this is serving us well, as we keep coming up against otherwise avoidable problems when we ship under-tested software. I would like to be able to come to management with a justification for hiring a dedicated software test engineer (someone who can both write automated tests and perform manual ones). Are there any good published studies that show the benefits of adding such a position to a small company? Where can I find information about costs associated with the position? I plan on doing a little number crunching on our own history, but having some external sources to point to would help bolster my case.

  • How to integrate Windows Server 2008 R2's NPS with Cisco switches?

    - by Massimo
    I need to evaluate in a lab environment the use of Windows Server 2008 R2's NPS for 802.1x authentication with Cisco Catalyst 3750 switches; the general idea is to only let clients connect to the company network if they can provide valid domain logon credentials, placing them in a restricted VLAN instead if they can't. NAP would also be a bonus, but it can be evaluated later; the main point now is only 802.1x authentication. Although I have very good knowledge of Windows and Active Directory (on the Microsoft side) and quite good knowledge of Catalyst switches (on the Cisco side), I'm totally new to 802.1x; I'd really like some general guidelines and help here, and some sort of implementation guide would also be very useful.

  • Hidden files in Nautilus after extracting ISO

    - by Luis Alvarado
    I need to first point to the image below to explain a bit about what I find weird here: I extracted the informacion from an ISO I from Nautilus I could only see two folders but from the terminal I can see the rest of the files and folders. This folders do not have the . character in from of them to hide them from plain sight. When I try to "Show hidden files" in Nautilus, Nautilus closes itself. It does not show the hidden folders or files. Somehow they are hidden without using the normal dot in the beginning of the name. The have my user permission but no way of seeing them from Nautilus. I can interact with them but the fact that they appear hidden when I can see them inside the ISO and after extracting them they disappear is what confuses me. What permission or setting makes this folders appear hidden and does not let Nautilus show them and like I said before, trying to show them with the "Show hidden files" option crashes Nautilus and exits it. Forcing me to have to open Nautilus again from the Launcher.

  • How not to suffer from ideologists when you're a pragmatic person?

    - by Lukas Eder
    My story: I'm a pragmatic person. Sometimes, the most simple solution to a problem to get the job done is the one that fits best for me, if its not an utter blasphemy and reproach to any design principles. Check out my answer to this question on stackoverflow. Simple. Works. Was accepted. Could be improved. Is clearly not perfect. And along comes this guy. He downvotes me, comments on the question how his answer is better, more accurate etc and calls me "plain wrong". Reminds me of this comic strip. :-) While on stackoverflow I can laugh at these things because those people are far away, in the real world I'm suffering from ideologies every now and then. Heck, I'm not creating a miracle piece of software, I need to keep that huge legacy thing running, and it's an adventure to me every day. I don't have the time or passion to beautify my code (or other people's code) to that extent. My question(s): How do you deal with ideologies / ideologists, when you're a pragmatic person? How do you deal with pragmatism / pragmatists, when you're an ideologic person? I'm interested in both point of views. Tell me your experience. But please, be fair, somewhat objective, and understand that you may NOT be entirely correct and your opinion is NOT the only true one... :-)

  • how to create iso dvd image for use with mac/osx "Disk Utility"?

    - by adolf garlic
    This seemed way easier on my pc. I would just pop a blank dvd in the drive, it asked what I wanted to do with it, to which I would respond, "burn dvd with nero" (paraphrasing), then I would pick "new" and just drag and drop the folders in there. Mac appears to have "Disk Utility" which just requires that I 'choose an image' but then doesn't bother to detail - how to do this - what the options mean e.g. format "mac OS extended (journaled)" is that ever going to be readable on a non mac machine? I want to create an ISO standard dvd as per the 'default' you'd get on nero. All the stuff on the web points to doing things with 'terminal' (the whole point of buying a mac was to get away from command line jiggery pokery - I'm trying to burn some photos not land a friggin lunar module here!) Please, if you can just provide some simple instructions on what I need to achive this I'd be extremely grateful. Ta muchley in advance.

  • Email solution for new domain [on hold]

    - by user196286
    I registered my domain at NameCheap, and have it hosted now at AWS Route 53. However, I'm at a loss for how now to set up sending transactional email. I hear Amazon SES is a good solution, but that requires me to verify my e-mail. I don't have email set up (no e-mail addresses at my domain nor a email client to receive the email verification). As an added wrinkle, I have my sitename.com bucket redirecting to www.sitename.com, and I'm hosting my site on Route 53 using www.sitename.com. However, does this screw things up if I need to switch my MX records since perhaps the 'www' throws things off (would it point to mail.www.sitename.com)?

  • High Availability Configuration using Heartbeat and Pacemaker

    - by pradeepchhetri
    I have the following setup: I have configured high availability between two load balancers (HAProxy) so that if HAProxy1 get down, the floating IP gets transferred to the other load balancer HAProxy2, hence all the clients will get the response from HAProxy2, which at the back-end is doing LB among the sme two webserver. This is for removing the single point of failure in case of only one HAProxy. Whenever I stops the hearbeat in HAProxy1, the floating IP goes to HAProxy2. But I want to configure such that whenever the process haproxy goes down, the floating IP should get assigned to HAProxy2. Can someone tell me how to implement it ?

  • SQL SERVER – Grouping by Multiple Columns to Single Column as A String

    - by pinaldave
    One of the most common questions I receive in email is how to group multiple column data in comma separate values in a single row grouping by another column. I have previously blogged about it in following two blog posts. However, both aren’t addressing the following exact problem. Comma Separated Values (CSV) from Table Column Comma Separated Values (CSV) from Table Column – Part 2 The question comes in many different formats but in following image I am demonstrating the same question in simple words. This is the most popular question on my Facebook page as well. (Example) Here is the sample script to build the sample dataset. CREATE TABLE TestTable (ID INT, Col VARCHAR(4)) GO INSERT INTO TestTable (ID, Col) SELECT 1, 'A' UNION ALL SELECT 1, 'B' UNION ALL SELECT 1, 'C' UNION ALL SELECT 2, 'A' UNION ALL SELECT 2, 'B' UNION ALL SELECT 2, 'C' UNION ALL SELECT 2, 'D' UNION ALL SELECT 2, 'E' GO SELECT * FROM TestTable GO Here is the solution which will build an answer to the above question. -- Get CSV values SELECT t.ID, STUFF( (SELECT ',' + s.Col FROM TestTable s WHERE s.ID = t.ID FOR XML PATH('')),1,1,'') AS CSV FROM TestTable AS t GROUP BY t.ID GO I hope this is an easy solution. I am going to point to this blog post in the future for all the similar questions. Final Clean Up Act -- Clean up DROP TABLE TestTable GO Here is the question back to you - Is there any better way to write above script? Please leave a comment and I will write a separate blog post with due credit.

  • Where is a good place to start to learn about custom caching in .Net

    - by John
    I'm looking to make some performance enhancements to our site, but I'm not sure exactly where to begin. We have some custom object caching, but I think that we can do better. Our Business We aggregate news stories on a news type of web site. We get approximately 500-1000 new stories per week. We have index pages that show various lists of the items and details pages that show the individual stories. Our Current Use case: Getting an Individual Story User makes a request The Data Access Layer(DAL) checks to see if the item is in cache and if item is fresh (15 minutes). If the item is not in cache or is not fresh, retrieve the item from SQL Server, save to cache and return to user. Problems with this approach The pull nature of caching means that users have to pay the waiting cost every time that the cache is refreshed. Once a story is published, it changes infrequently and I think that we should replace the pull model with something better. My initial thoughts My initial thought is that stories should ALL be stored locally in some type of dictionary. (Cache or is there another, better way?). If the story is not found, then make a trip to the database, update the local dictionary and send the item back. Since there may be occasional updates to stories, this should be an entirely process from the user. I watched a video by Brent Ozar, How StackOverflow Scales SQL Server, in which Brent states "the fastest database query is the one that you don't make". Where do I start? At this point, I don't know exactly what the solution is. Is it caching? Is there a better way of using local storage? Do I use a Dictionary, OrderedDictionary, List ? It seems daunting and I'm just looking for some good starting points to learn more about how to do this type of optimization.

  • How to set up JBoss with S3_Ping on AWS?

    - by Jonik
    I'm looking into running clustered JBoss on Amazon Web Services (AWS). I'd like to try out S3_PING, i.e. making JBoss use an S3 bucket for dynamic node discovery etc, since no multicast is available. I found a piece of example config XML related to S3_Ping, but I'm not sure where in JBoss installation you're supposed to configure this. So, what JBoss config files would I need to tweak to get S3_PING working? Can anyone point me to a more complete example? JBoss 5.1.0 GA. (This is probably more a JGroups/JBoss question than anything else. I've already got the S3 bucket for this set up, so no problem there.)

  • 2D Collision masks for handling slopes

    - by JiminyCricket
    I've been looking at the example at: http://create.msdn.com/en-US/education/catalog/tutorial/collision_2d_perpixel and am trying to figure out how to adjust the sprite once a collision has been detected. As David suggested at XNA 4.0 2D sidescroller variable terrain heightmap for walking/collision, I made a few sensor points (feet, sides, bottom center, etc.) and can easily detect when these points actually collide with non-transparent portions of a second texture (simple slope). I'm having trouble with the algorithm of how I would actually adjust the sprite position based on a collision. Say I detect a collision with the slope at the sprite's right foot. How can I scan the slope texture data to find the Y position to place the sprite's foot so it is no longer inside the slope? The way it is stored as a 1D array in the example is a bit confusing, should I try to store the data as a 2D array instead? For test purposes, I'm thinking of just using the slope texture alpha itself as a primitive and easy collision mask (no grass bits or anything besides a simple non-linear slope). Then, as in the example, I find the coordinates of any collisions between the slope texture and the sprite's sensors and mark these special sensor collisions as having occurred. Finally, in the case of moving up a slope, I would scan for the first transparent pixel above (in the texture's Ys at that X) the right foot collision point and set that as the new height of the sprite. I'm a little unclear also on when I should make these adjustments. Collisions are checked on every game.update() so would I quickly change the position of the sprite before the next update is called? I also noticed several people mention that it's best to separate collision checks horizontally and vertically, why is that exactly? Open to any suggestions if this is an inefficient or inaccurate way of handling this. I wish MSDN had provided an example of something like this, I didn't know it would be so much more complex than NES Mario style pure box platforming!

  • ASP.NET: Serializing and deserializing JSON objects

    - by DigiMortal
    ASP.NET offers very easy way to serialize objects to JSON format. Also it is easy to deserialize JSON objects using same library. In this posting I will show you how to serialize and deserialize JSON objects in ASP.NET. All required classes are located in System.Servicemodel.Web assembly. There is namespace called System.Runtime.Serialization.Json for JSON serializer. To serialize object to stream we can use the following code. var serializer = new DataContractJsonSerializer(typeof(MyClass)); serializer.WriteObject(myStream, myObject); To deserialize object from stream we can use the following code. CopyStream() is practically same as my Stream.CopyTo() extension method. var serializer = new DataContractJsonSerializer(typeof(MyClass));   using(var stream = response.GetResponseStream()) using (var ms = new MemoryStream()) {     CopyStream(stream, ms);     results = serializer.ReadObject(ms) as MyClass; } Why I copied data from response stream to memory stream? Point is simple – serializer uses some stream features that are not supported by response stream. Using memory stream we can deserialize object that came from web.

  • Koans, now available in Python flavor

    - by Greg Malcolm
    Recently a Python developer friend with whom I was pair programming with suggested that I show him how to write a little Ruby. I responded by telling him to check out Ruby Koans as a starting point. However I wanted to try that in reverse at the same time with me learning some Python. I did a bit of googling, and sure enough someone had started writing some Python Koans. It just needed finishing... So, a few weeks later Python Koans is now complete and ready for action! It is available through Mercurial on Bitbucket: http://bitbucket.org/gregmalcolm/python_koans/wiki/Home It is also mirrored on Github: http://wiki.github.com/gregmalcolm/python_koans/ Converting it was fairly easy. Aside from the differing philosophical approaches behind the two languages, Ruby and Python are fairly similar. We had to come up with completely new material for a few subjects like multiple inheritance and decorators, but for most features in Ruby there is something roughly comparable in Python. I highly recommend writing tests (or koans) as a means to lean a new language or framework. I've learned a lot from doing this.

  • Difference between multiple NS and NS having multiple A

    - by Jake
    I found this Can an NS Record Point To Multiple A Records?, but wonders what is the difference, if any. For example: mydomain.com. IN NS ns1.myhost.com. mydomain.com. IN NS ns2.myhost.com. ns1.myhost.com. IN A 111.222.333.1 ns2.myhost.com. IN A 111.222.333.2 versus mydomain.com. IN NS ns.myhost.com. ns.myhost.com. IN A 111.222.333.1 ns.myhost.com. IN A 111.222.333.2 EDIT: actually, come to think of it, it could be said the same for MX records. Any breaking differences? EDIT 2: then again, MX allow use of priority values so its a different case, in that one-ip-per-domain is more useful sometimes.

  • Edd strikes again &ndash; IronRuby for Rubyists on InfoQ

    - by Eric Nelson
    Colleague, friend and generally top guy on IronRuby Edd Morgan has just been published over on InfoQ. To wet the appetite… a snippet or three. IronRuby for Rubyists IronRuby is Microsoft's implementation of the Ruby language we all know and love with the added bonus of interoperability with the .NET framework — the Iron in the name is actually an acronym for 'Implementation running on .NET'. It's supported by the .NET Common Language Runtime as well as, albeit unofficially, the Mono project. You'd be forgiven for harbouring some question in your mind about running a dynamic language such as Ruby atop the CLR - that's where the DLR (Dynamic Language Runtime) comes in. The DLR is Microsoft's way of providing dynamic language capability on top of the CLR. Both IronRuby and the DLR are, as part of Microsoft's commitment to open source software, available as part of the Microsoft Public License on GitHub and CodePlex respectively… And Metaprogramming with IronRuby The art and science of metaprogramming — especially in Ruby, where it's an absolute joy — is something that could very easily span an entire article. As you would hope, IronRuby code is fully able to manipulate itself allowing you to bend your classes to your whim just as you would expect with a good dynamic language… And Riding the irails? So let's get to the point. I think it's a solid bet to make that a large proportion of Ruby programmers are familiar with the Rails framework - perhaps it's even safe to assume that most were first led to the Ruby language by the siren song of the Rails framework itself. Long story short, IronRuby is compatible enough to run your Rails app… Now… get yourself over to the full article and also check out some of Edds other work below.

  • Should a programmer "think" for the client?

    - by P.Brian.Mackey
    I have gotten to the point where I hate requirements gathering. Customer's are too vague for their own good. In an agile environment, where we can show the client a piece of work to completion it's not too bad as we can make small regular corrections/updates to functionality. In a "waterfall" type in environment (requirements first, nearly complete product next) things can get ugly. This kind of environment has led me to constantly question requirements. E.G. Customer wants "automatically convert input to the number 1" (referring to a Qty in an order). But what they don't think about is that "input" could be a simple type-o. An "x" in a textbox could be a "woops" not I want 1 of those "toothpaste" products. But, there's so much in the air with requirements that I could stand and correct for hours on end smashing out what they want. This just isn't healthy. Working for a corporation, I could try to adjust the culture to fit the agile model that would help us (no small job, above my pay grade). Or, sweep ugly details under the rug and hope for the best. Maybe my customer is trying to get too close to the code? How does one handle the problem of "thinking for the client" without pissing them off with too many questions?

  • Implementing an automatic navigation mesh generation for 2d top down map?

    - by J2V
    I am currently in the middle of implementing an A* pathfinding for enemies. In order to implement the actual A* logic, I need a navigation mesh for my map. I am working on a 2D top down rpg map. The world is static, meaning there is no requirement for dynamic runtime mesh generation. My world objects are pixel based, not tile based and have associated data with them such as scale, rotation, origin etc. I will obviously need some vertex data being generated from my world objects, maybe create a polygon generation from color data? I could create a colormap with objects for my whole map, but I have no idea how to begin creating nav mesh polygons. How would an actual navigation mesh generation look like with this kind of available information? Can anyone maybe point to some great resources? I have looked into some 3D nav mesh tools, but they seem kind of overly complex for my situation and also have a lot of their req data available from models. Thanks a lot in advance! I have been trying to get my head around it for some time now.

  • how to find a good data center?

    - by drewda
    At my start-up, we're getting to the point where we should be hosting our servers at a data center. I'd appreciate any tips and tricks y'all can offer on finding a reputable place to colocate our racks. Are there any Web sites with customer reviews of data centers or should I just be asking around at techie events? Are unlimited bandwidth plans a gimmick or becoming the norm? Is it worth establishing a redundant set of machines at a second data center from Day One? Or just do offsite back-ups? Thanks for your suggestions.

  • How do I stop ubuntu from detaching minimize/maximuze/close buttons?

    - by Shahbaz
    Some time ago I managed to get ubuntu to keep the window menubars in the menu rather than the bar above (I'm not sure if this part is unity or compiz, or what's the difference). That was by removing indicator-appmenu Anyway, so now everything is fine except one thing: If I have a window that is full screen, the minimize/maximize/close buttons are still grabbed by the bar on the top. Usually this doesn't cause a problem because the upper-left corner of the full screen window and the whole screen are not too far apart. However, one thing happens to me a lot, and that is I am working on something (programming), then I need to check some things from other places so I open some windows, see what I want and switch back to my work. Those windows however are temporary so at some point I want to close them. Now here's what happens: I have the focus on some window and I can't close the maximized window behind it unless I click on the window first, so that the buttons appear and then close it. I couldn't find anything on the internet about this. Is this something that's hardcoded in unity/compiz/whatever or is there actually a way to configure this?

  • How can I convince my boss to invest into the developer environment?

    - by user95291
    Our boss said that developers should have fewer mistakes so the company would have money for displays, servers etc. An always mentioned example is a late firing of an underperforming colleague whose salary would have covered some of these expenses. On the other hand it happened a few times that it took a few days to free up some disk space on our servers since we can't get any more disk. The cost of mandays was definitely higher than the cost of a new HDD. Another example is that we use 14-15" notebooks for development and most of the developers get external displays after they spent one year at the company. The price of a 22-24" display is just a small fraction of a developers annual salary. Devs say that they like the company because of other reasons (high quality code, interesting projects etc.) but this kind of issues not just simply time-consuming but also demotivate them. In the point of view of the developers it seems that the boss always can find an issue in the past which they could have been done better so it's pointless to work better to get for a second display/HDD/whatever. How can I convince my boss to invest more into development environment? Is it possible to break this endless loop?

  • Inconsistent accessibility error in xna.

    - by Tom
    Hey all, you may remember me asking a question regarding a snake game I was creating about two weeks ago. Well I'm quite far now into making the game (thanks to a brilliant tutorial I found). But I've come across the error described named above. So heres my problem; I have a SnakeFood class that has a method called "Reposition". In the game1 class I have a method called "UpdateInGame" which calls the reposition method to load an orange that spawns in a random place every second. My latest piece of code changed the reposition method to allow the snake I have on the screen to not be overlapped by the orange that randomly spawns. Now I get the error (in full): Error 1 Inconsistent accessibility: parameter type 'TheMathsSnakeGame.Snake' is less accessible than method 'TheMathsSnakeGame.SnakeFood.Reposition(TheMathsSnakeGame.Snake)' C:\Users\Tom\Documents\Visual Studio 2008\Projects\TheMathsSnakeGame\TheMathsSnakeGame\SnakeFood.cs 33 21 TheMathsSnakeGame I understand what the errors trying to tell me but having changed the accessiblity of the methods, I still can't get it to work. Sorry about the longwinded question. Thanks in advance :) Edit: Code I'm using (Game1 Class) private void UpdateInGame(GameTime gameTime) { //Calls the oranges "reposition" method every second if (gameTime.TotalGameTime.Milliseconds % 1000 == 0) orange.Reposition(sidney); sidney.Update(gameTime); } (SnakeFood Class) public void Reposition(Snake snake) { do { position = new Point(rand.Next(Grid.maxHeight), rand.Next(Grid.maxWidth)); } while (snake.IsBodyOnPoint(position)); }

  • Cannot install Windows 8 Transformation Pack on Windows 7

    - by Mehper C. Palavuzlar
    I am trying to install Windows 8 Transformation Pack v4.0 on my Sony Vaio laptop with the following options: When I run (as administrator) the setup file, it starts to install but gives the following error at some point: The file 'C:\Windows\Fonts\segoui.ttf' could not be opened. Please check that your disk is not full and that you have access to the destination directory. Since I run the installer as administrator, this error message seems strange to me. Segoe UI font is also installed on my PC. When I try to install with default system fonts (without Segoe UI), it gives the same error again: What should I do to solve this problem?
