• How long can you be out of the MS market before it affects your career [closed]

  - by dave

  I've been working with .Net since it first came out and have done my best to use the latest and greatest things from Redmond. That being said, I've been working for the past year in the Python/Unix/Web world. In order to keep myself relevant in the MS world, I've been working part-time on a WPF project but I do not know how much longer that work will continue. So my question is: If I were to move totally to the Unix/Python/Web world, how long could I stay there before it starts getting hard to get another MS job? I am trying not to burn bridges in my career as I've found MS jobs pay better and tend to be more plentiful. PS: I like my Python job since it is something new and I get to work from home. It has provided a different view on coding that I've found useful. EDIT: I was out of the MS market for 12 months before attempting to get another MS job. No-one said "Gee you've been gone a while" but I did get a conspicuous lack of responses to job applications. My feeling is that the head-hunters do not bother to look beyond your last job. In the end, I got employment via my own network rather than the pimps. So, to answer my question: "not long, especially if you trust your career to head hunters."

• Remote Working & Relocation

  - by James Burgess

  Sorry if this question is a duplicate, I did some extensive searching and found nothing on quite the same topic (though a couple on partially-overlapping topics). Recently, whilst on holiday in Munich, Germany, I was taken aback by the sheer number of programming-related posts available in the city that I easily qualify for (both in terms of knowledge, and experience). The advertised working environments seemed good and the pay seemed to be at least as good as what I'd expect here in the UK. Probably 80% of the advertisements I saw on the underground were for IT-related jobs, and a good 60% of those I was easily qualified for. At the moment, I work as a freelancer mostly on web and small software projects, but seeing the vast availability of jobs in Munich versus my local area has me thinking about remote working. I'm unable to relocate for a job for the next 3 years (my wife has a contract to continue being a doctor at her current hospital for that time) but would almost certainly be open to it after that (after all, my wife and I both love Munich). In the meanwhile, I would be very interested in remote-working. So, my question is thus do companies ever take on remote workers (even with semi-frequent trips to the office) from abroad, with a view to later relocation? And, if so, how do you go about broaching the topic with a recruiter when getting in contact about a job posting? Language isn't a barrier for me, here, as 90% of the jobs I've looked up in Munich don't require German speakers (seems they have a big recruiting market abroad). I'm also under no illusions about the disadvantages of remote working, but I'm more interested in the viability of the scenario rather than the intricacies (at least at this point). I'd really appreciate any contributions, especially from those who have experience with working in such a scenario!

• Create device receive SMS parse to text ( SMS Gateway )

  - by Chris Okyen

  I want to use a server as a device to run a script to parse a SMS text in the following way. I. The person types in a specific and special cell phone number (Similar to Facebook’s 32556 number used to post on your wall) II. The user types a text message. III. The user sends the text message. IV. The message is sent to some kind of Device (the server) or SMS Gateway and receives it. V. The thing described above that the message is sent to then parse the test message. I understand that these three question will mix Programming and Server Stuff and could reside here or at DBA.SE How would I make such a cell phone number (described in step I) that would be sent to the Device? How do I create the device that then would receive it? Finally, how do I Parse the text message? I don't want to pay for cloud space, server scripting stuff or server space; I want to just use a free webserver to do this totally free - meaning I will have to do more on my own... My question can be seen in more depth in this visual flowchart

• Is an app that does nothing but link to a web site functional enough to meet Apple's iOS guidelines?

  - by Pointy

  I don't hang out on Programmers enough to know whether this question is "ok", so my apologies if not. I tried to make the title obvious so at least it can be closed quickly :-) The question is simple. My employer wants "home screen presence" (or at least the possibility thereof) on iOS devices (also Android but I'm mostly interested in Apple at the moment). Our actual application will be a pure web-delivered mobile-friendly application, so what we want on the homescreen is basically something that just acts as a link to bring up Safari (or Chrome now I guess; not important). I'm presuming that that's more-or-less possible; if not then that would be interesting too. I know that the Apple guidelines are such that low-functionality apps are generally rejected out of hand. There are a lot of existing apps that seem (to me) less functional than a link to something useful, but I'm not Apple of course. Because this seems like a not-too-weird situation, I'm hoping that somebody knows it's either definitely OK (maybe because there are many such apps) or definitely not OK. Note that I know about things like PhoneGap and I don't want that, at least not at the moment.

• Why don't C++ Game Developers use the boost library?

  - by James

  So if you spend any time viewing / answering questions over on Stack Overflow under the C++ tag, you will quickly notice that just about everybody uses the boost library; some would even say that if you aren't using it, you're not writing "real' C++ (I disagree, but that's not the point). But then there is the game industry, which is well known for using C++ and not using boost. I can't help but wonder why that is. I don't care to use boost because I write games (now) as a hobby, and part of that hobby is implementing what I need when I am able to and using off-the-shelf libraries when I can't. But that is just me. Why don't game developers, in general, use the boost library? Is it performance or memory concerns? Style? Something Else? I was about to ask this on stack overflow, but I figured the question is better asked here. EDIT : I realize I can't speak for all game programmers and I haven't seen all game projects, so I can't say game developers never use boost; this is simply my experience. Allow me to edit my question to also ask, if you do use boost, why did you choose to use it?

• Automated Acceptance tests under specific contraints

  - by HH_

  This is a follow up to my previous question, which was a bit general, so I'll be asking for a more precise situation. I want to automate acceptance testing on a web application. Briefly, this application allows the user to create contracts for subscribers with the two constraints: You cannot create more than one contract for a subscriber. Once a contract is created, it cannot be deleted (from the UI) Let's say TestCreate is a test case with tests for the normal creation of a contract. The constraints have introduced complexities to the testing process, mainly dependencies between test cases and test executions. Before we run TestCreate we need to make sure that the application is in a suitable state (the subscriber has no contract) If we run TestCreate twice, the second run will fail since the state of the application will have changed. So we need to revert back to the initial state (i.e. delete the contract), which is impossible to do from the UI. More generally, after each test case we should guarantee that the state is reverted back. And since, in this case, it is impossible to do it from the UI, how do you handle this? Possible solution: I thought about doing a backup of the database in the state that I desire, and after each test case, run a script which deletes the db and restores the backup. However, I find that to be too heavy to do for each single test case. In addition, what if some information are stored in files? or in multiple or unaccessible databases? My question: In this situation, what would an experienced tester do to write automated and maintanable tests. Thank you. More info: I'm trying to integrate tests into a BDD framework, which I find to be a neat solution for test documentation and communication, but it does not solve this particular problem (it even makes it harder)

• How does Wikipedia's SEO work?

  - by Josh Siegl

  i'm sorry if this question is misplaced or doesn't belong here. I'm currently developing an app for android and IOS and of course i'm thinking about the best ways to market it. Last night I Google'd somebody else's app and the third link in was a Wikipedia page on it, I never even thought of apps having Wikipedia pages, but alas there it was. And of course it was very helpful in determining exactly what the app did and in what cases it was useful for (something that's absolutely crucial for potential customers to understand). So then I got to thinking that I should create a Wiki for my app, but how does Wikipedia apply SEO? I know that the question could be overly complicated or specific, i'm just looking for general answers. For instance when somebody Google's my app, where does Wikipedia display on the results? When I create a Wiki for my app, how do I ensure that the Wikipedia page shows in the search results (is there any way to do that? ) I'm sure i'll find all of this out later when I create a Wiki for my app, I guess i'm just asking this out of curiosity. So how does Wikipedia's search engine optimization work? (on a page by page basis)

• What's the proper term for a function inverse to a constructor? Deconstructor, destructor, or something else?

  - by Petr Pudlák

  Edit: I'm rephrasing the question a bit. Apparently I caused some confusion because I didn't realize that the term destructor is used in OOP for something quite different - it's a function invoked when an object is being destroyed. In functional programming we (try to) avoid mutable state so there is no such equivalent to it. (I added the proper tag to the question.) Instead, I've seen that the record field for unwrapping a value (especially for single-valued data types such as newtypes) is sometimes called destructor or perhaps deconstructor. For example, let's have (in Haskell): newtype Wrap = Wrap { unwrap :: Int } Here Wrap is the constructor and unwrap is what? I've seen both, for example: ... Most often, one supplies smart constructors and destructors for these to ease working with them. ... at Haskell wiki, or ... The general theme here is to fuse constructor - deconstructor pairs like ... at Haskell wikibook (here it's probably meant in a bit more general sense). The questions are: How do we call unwrap in functional programming? Deconstructor? Destructor? Or by some other term? And to clarify, is this terminology applicable to other functional languages, or is it used just in the Has

• Why do memory-managed languages retain the `new` keyword?

  - by Channel72

  The new keyword in languages like Java, Javascript, and C# creates a new instance of a class. This syntax seems to have been inherited from C++, where new is used specifically to allocate a new instance of a class on the heap, and return a pointer to the new instance. In C++, this is not the only way to construct an object. You can also construct an object on the stack, without using new - and in fact, this way of constructing objects is much more common in C++. So, coming from a C++ background, the new keyword in languages like Java, Javascript, and C# seemed natural and obvious to me. Then I started to learn Python, which doesn't have the new keyword. In Python, an instance is constructed simply by calling the constructor, like: f = Foo() At first, this seemed a bit off to me, until it occurred to me that there's no reason for Python to have new, because everything is an object so there's no need to disambiguate between various constructor syntaxes. But then I thought - what's really the point of new in Java? Why should we say Object o = new Object();? Why not just Object o = Object();? In C++ there's definitely a need for new, since we need to distinguish between allocating on the heap and allocating on the stack, but in Java all objects are constructed on the heap, so why even have the new keyword? The same question could be asked for Javascript. In C#, which I'm much less familiar with, I think new may have some purpose in terms of distinguishing between object types and value types, but I'm not sure. Regardless, it seems to me that many languages which came after C++ simply "inherited" the new keyword - without really needing it. It's almost like a vestigial keyword. We don't seem to need it for any reason, and yet it's there. Question: Am I correct about this? Or is there some compelling reason that new needs to be in C++-inspired memory-managed languages like Java, Javascript and C#?

• Zoom Layer centered on a Sprite

  - by clops

  I am in process of developing a small game where a space-ship travels through a layer (doh!), in some situations the spaceship comes close to an enemy space ship, and the whole layer is zoomed in on the two with the zoom level being dependent on the distance between the ship and the enemy. All of this works fine. The main question, however, is how do I keep the zoom being centered on the center point between the two space-ships and make sure that the two are not off-screen? Currently I control the zooming in the GameLayer object through the update method, here is the code (there is no layer repositioning here yet): -(void) prepareLayerZoomBetweenSpaceship{ CGPoint mainSpaceShipPosition = [mainSpaceShip position]; CGPoint enemySpaceShipPosition = [enemySpaceShip position]; float distance = powf(mainSpaceShipPosition.x - enemySpaceShipPosition.x, 2) + powf(mainSpaceShipPosition.y - enemySpaceShipPosition.y,2); distance = sqrtf(distance); /* Distance > 250 --> no zoom Distance < 100 --> maximum zoom */ float myZoomLevel = 0.5f; if(distance < 100){ //maximum zoom in myZoomLevel = 1.0f; }else if(distance > 250){ myZoomLevel = 0.5f; }else{ myZoomLevel = 1.0f - (distance-100)*0.0033f; } [self zoomTo:myZoomLevel]; } -(void) zoomTo:(float)zoom { if(zoom > 1){ zoom = 1; } // Set the scale. if(self.scale != zoom){ self.scale = zoom; } } Basically my question is: How do I zoom the layer and center it exactly between the two ships? I guess this is like a pinch zoom with two fingers!

• Google analytics - drop in traffic

  - by user1001421

  Bit of a general question here. We are in the process of converting a number of our clients from older web sites to new ones. The problem we are getting, and sorry for being so general here, is we are getting a sharp decline in traffic as reported on Google Analytics. It's not a gradual decline, it seems to hit almost as soon as the new site goes live. I've just got a few questions to see if there is something we are doing wrong: a) We are using the same analytics accounts going from old to new site. Is this a bad idea? b) The actual analytics code is integrated into the pages using a server-side include. IS this a bad idea? c) We structure our sites differently to our old site. IE. The old sites would pretty must have all the web pages in the root directory, and hyperlinks would be linked to the page files: EG. <a href="somepage.aspx">Link</a> Our new sites now have a directory structure that pretty much reflects the navigation structure, and hyper links link to the pages directory instead of the actual page: EG. <a href="/new-items/shoes/">New shoes</a> Is this a bad idea. I'm really searching for a needle in a haystack here. Would appriciate any help or advice as to why we are getting such a sharp and sudden drop in traffic. Again, so this is such a general question. Thanks in advance.

• Lubuntu: How do I arrange windows with keyboard shortcuts?

  - by iveand

  I have been testing with Lubuntu and have found it really pleasant. However, I cannot find an answer for one essential (for me) feature: being able to arrange windows with keyboard shortcuts. In Ubuntu this is done with the "Grid" plugin in "compizconfig-settings-manager". Unity uses this as well for window arranging. I am not interested in the "drag to the left to take up 1/2 the screen", but rather just the "hit some key combo" to put the active window to the left 1/2 of the screen, for example. I found this entry in "askubuntu" asking a very similar question: Is there a way to make Openbox behave like the Compiz Grid plugin? But it seems the "answer to this question", namely pyTile (http://sourceforge.net/projects/pytile/), doesn't do what I would like it to do. I don't want to tile all current windows, I want to resize one window at a time as I specify (left, right, top, center, bottom, 1/2, 2/3, 1/3, etc.). And I would prefer to do so with the keyboard. I think it possible to install compiz in Lubuntu, but this seems like "overkill" for this one feature (Grid keyboard shortcuts). Any help out there? It would REALLY MAKE MY DAY!!!

• Is it possible to keep nm-applet running between invocations of WM startup?

  - by serverninja

  I am using nm-applet to interface with NetworkManager, running xmonad as a window manager. My X sessions (including nm-applet) are set up with a /usr/local/bin/xmonad.start script. My question is, how can I keep nm-applet running in the background as long as X is running, but not necessarily xmonad? As mentioned above, it is being started with xmonad (and dying with it when xmonad is restarted, etc). I am using gdm to manage my X sessions, and I'm running 10.10. Where's a good place to start nm-applet to suit my particular needs? I need to remove it from the control of xmonad, but don't know where to start it otherwise. Any help, tips, etc appreciated. Edit: problem seems to be with how I have integrated xmonad. I have the session script as a file in /usr/share/xsessions/xmonad.desktop with the following contents: [Desktop Entry] Encoding=UTF-8 Name=XMonad Comment=Lightweight tiling window manager Exec=/usr/local/bin/xmonad.start Icon=xmonad.png Type=XSession /usr/local/bin/xmonad.start contains the following: #!/bin/bash xrdb -merge ~/.Xresources xcompmgr -c & trayer --edge top --align right --SetDockType true --SetPartialStrut true --expand true --width 8 --heighttype pixel --height 18 --transparent true --alpha 0 --tint 0x000000 & gnome-settings-daemon & gnome-screensaver & if [ -x /usr/bin/nm-applet ] ; then nm-applet --sm-disable & fi /usr/bin/urxvtd -q -o -f & eval `ssh-agent` & if [ -x /usr/bin/gnome-power-manager ] ; then sleep 1 gnome-power-manager & fi /usr/bin/gnome-volume-control-applet & exec xmonad The question is how do I integrate xmonad, gdm, X, etc in such a manner to replicate the behavior I currently have except with nm-applet (and possibly other programs) running whether or not xmonad is?

• Best industry to work for as a developer.

  - by The Elite Gentleman

  Hi guys, Hmmm, StackOverflow now warns me of: "The question you're asking appears subjective and is likely to be closed." I've been an avid java (J2SE, JEE) developer for over 5 years now (and I'm not complaining, even though I want to go back to Delphi & C++). My contract has just ended and I'm wondering of possible job to further tackle. I've done banking and insurance industry for all my career (with 1 year on a Fortuner 500 company) and pretty much, banking is the slowest (and boring) industry to work for (IMHO) since they're strict in their business practices (fair enough). The upside is that they pay. My question is: What is the best industry for a developer, who tends to get bored relatively quickly, to work for? Is it also worthwhile for me to do consultancy (and if so, what type of consultancy)? PS There's no gaming industry in South Africa, so suggesting it requires that I have to travel to a country where gaming is alive! I don't see the Community Wiki checkbox, so I don't know how to make this a wiki.

• Does an inexperienced programmer need an IDE?

  - by Torben Gundtofte-Bruun

  Reading this other question makes me wonder if I (as an absolute beginner PHP programmer) should stick with WAMP and Notepad++ or to switch to some IDE like Eclipse. It's understandable that skilled developers will benefit from a big shiny IDE. But why should an absolute beginner use an IDE? Do the benefits outweigh the extra challenge of learning the IDE on top of learning to develop? Update for clarification: My goal is to get some basic programming experience. By choosing PHP and WAMP (and FogBugz and Kiln) I hope to avoid having to navigate the tricky / messy OS specifics and compiling etc. and just focus on basic functionality like an online user registration form. I've got lots of theoretical understanding from university a decade ago but no practical experience. I want to remedy that with a hobby project that would be similar to a real-world sellable web app. There are so many questions to ask. So many pitfalls I probably have to blunder into. This question is just one piece (my first!) of that puzzle.

• Managing constant buffers without FX interface

  - by xcrypt

  I am aware that there is a sample on working without FX in the samplebrowser, and I already checked that one. However, some questions arise: In the sample: D3DXMATRIXA16 mWorldViewProj; D3DXMATRIXA16 mWorld; D3DXMATRIXA16 mView; D3DXMATRIXA16 mProj; mWorld = g_World; mView = g_View; mProj = g_Projection; mWorldViewProj = mWorld * mView * mProj; VS_CONSTANT_BUFFER* pConstData; g_pConstantBuffer10->Map( D3D10_MAP_WRITE_DISCARD, NULL, ( void** )&pConstData ); pConstData->mWorldViewProj = mWorldViewProj; pConstData->fTime = fBoundedTime; g_pConstantBuffer10->Unmap(); They are copying their D3DXMATRIX'es to D3DXMATRIXA16. Checked on msdn, these new matrices are 16 byte aligned and optimised for intel pentium 4. So as my first question: 1) Is it necessary to copy matrices to D3DXMATRIXA16 before sending them to the constant buffer? And if no, why don't we just use D3DXMATRIXA16 all the time? I have another question about managing multiple constant buffers within one shader. Suppose that, within your shader, you have multiple constant buffers that need to be updated at different times: cbuffer cbNeverChanges { matrix View; }; cbuffer cbChangeOnResize { matrix Projection; }; cbuffer cbChangesEveryFrame { matrix World; float4 vMeshColor; }; Then how would I set these buffers all at different times? g_pd3dDevice->VSSetConstantBuffers( 0, 1, &g_pConstantBuffer10 ); gives me the possibility to set multiple buffers, but that is within one call. 2) Is that okay even if my constant buffers are updated at different times? And do I suppose I have to make sure the constantbuffers are in the same position in the array as the order they appear in the shader?

• Prevent Click Fraud in Advertisement system with PHP and Javascript

  - by CodeDevelopr

  I would like to build an Advertising project with PHP, MySQL, and Javascript. I am talking about something like... Google Adsense BuySellAds.com Any other advertising platform My question is mainly, what do I need to look out for to prevent people cheating the system and any other issues I may encounter? My design concept. An Advertisement is a record in the Database, when a page is loaded, using Javascript, it calls my server which in turn will use a PHP script to query the Database and get a random Advertisement. (It may do kore like get an ad based on demographics or other criteria as well) The PHP script will then return the Advertisement to the server/website that is calling it and show it on the page as an Image that will have a special tracking link. I will need to... Count all impressions (when the Advertisement is shown on the page) Count all clicks on the Advertisement link Count all Unique clicks on the Advertisement link My question is purely on the query and displaying of the Advertisement and nothing to do with the administration side. If there is ever money involved with my Advertisement buying/selling of adspace, then the stats need to be accurate and make sure people can't easily cheat the system. Is tracking IP address really the only way to try to prevent click fraud? I am hoping someone with some experience can clarify I am on the right track? As well as give me any advice, tips, or anything else I should know about doing something like this?

• Trying to find a recent - PHP book - that utilizes SOLID principles! [closed]

  - by darga33

  Pulling my hair out! I have heard of Martin Fowler's book PoEAA and the other book Head First OOA OOD but those are not in PHP. I desperately want to read them, but ONLY in PHP utilizing the - SOLID acronym - principles! Does anyone know of the absolute best, most recent PHP book that utilizes the SOLID principles and GRASP, and all the other best practices? I want to learn from the best possible source! Not beginner books! I already understand OOP. This seems like an almost impossible question to find the answer to and so I thought, hey, might as well post on stackexchange!! Surely someone out there must know!!!!!!!!!! Or if noone happens to know, Maybe they know of an open source application that utilizes these principles that is relatively small that is not a framework. Something that I can go through every single class, and spend time understanding the insides and outs of how the program was developed. Thanks so much in advance! I really really really really appreciate it! Well it looks like we aren't supposed to ask about best books, so nevermind this question! Sorry about that!

• What stops HTML5 and JS apps to perform as good as native apps?

  - by Amogh Talpallikar

  From what I understand, HTML is a mark-up language, so is the content of XAML, XIB and whatever Android uses and other native UI development frameworks. JavaScript is a programming language used along with it to handle client side scripting which will include things like event handling, client side validations and anything else C#,Java,Objective-C or C++ do in various such frameworks. There are MVC/MVVM patterns available in form frameworks like Sencha's, Angular etc. We have localStorage in form of both sqlite and key-value store as other frameworks have and you have API specification for almost everything that it missing. Whenever a native UI frameworks has to render UI , it has to parse a similar the markup and render the UI. Question break-down What stops from doing the same in HTML and JS itself ? Instead of having a web-control or browser as a layer in between why can't HTML(along with CSS) and JS be made to perform the same way ? Even if there is a layer,so does .net runtime and JVM are in other cases where C++,C are not being used. So Lets take the case of Android, like Dalvik, why Can't Chromium be another option(along with dalvik and NDK) where HTML does what android markup does and JavaScript is used to do what Java does ? So the Question is, Even if current implementations aren't as good, but theoretically is it possible to get HTML5 based applications to work as other native apps specially on mobile ?

• Remote server's x menus without vino, vnc etc

  - by Fredde

  A question where both google searches, as well as askubuntu and ubuntu forums searches fails though rephrasing the question a number of times. Have a Lubuntu server with some storage and functions and a lubuntu laptop. Previous when running winXP, I had Xming, could start a x-session on the server, got the lxpanel on the laptop, switching, running x-programs without a hitch though the lxpanel menu. A very neat and convenient solution. However the winXP crashed, me moving to lubuntu also for the laptop. still things work, I ssh into the server and can start x-programs without a hitch. But, as with all graphical desktops, I at times need access to the lx menus on the server to find programs and here the problems arise, most finding I got talk about installing VNC, vino etc overkills, avoiding existing X-integration between the servers. I'll like to do as I did with Xming, see the menu system on the server, in my "client's" xwin? Just to see the servers installed software without colliding with the laptop X-server, just using it as normal X-apps.

• Why don't windows of the same application behave as they should?

  - by Yuttadhammo

  Somewhere along the upgrade path, Unity has developed some strange logic behind window layering. First, before Oneiric, there was a way to see all the windows of an application - I think it was when you click on the icon in the launcher. Now, clicking on the icon often does nothing. Suppose I have two terminals open, one behind this Firefox window, and one in front of it. Clicking on the launcher does nothing - the only way to find the second terminal, afaics, is to move the Firefox window or use the task switcher. Secondly, once I have both terminals on top, then I decide to close one of them, suddenly they both disappear (the second one, for some reason, has gone into hiding behind the Firefox window). Third (though I can't pin it down now), sometimes when a window is on top, focus is still on a window in back; I click on the top x to close the window in front, only to find I've closed an important window in the back. (Update: this question details the problem) I can't really believe these are bugs, since they seem too obvious to not have been fixed by now. My question is, am I missing something? Some compiz option I can set to make it act like it used to? Or is this really how Unity is supposed to act?

• Tree Surgeon 2.0 - The future on the T4 Express

  - by Malcolm Anderson

  If you've never been a fan of TreeSurgeon (http://treesurgeon.codeplex.com/) then skip this post.However, if have been there have been some interesting developments over the last couple of years.The biggest one is T4Recently Bill Simser wrote a detailed post about the potential future of tree surgeon, called "Tree Surgeon - Alive and Kicking or Dead and Buried" He raised the question:Times have changed. Since that last release in 2008 so much has changed for .NET developers. The question is, today is the project still viable? Do we still need a tool to generate a project tree given that we have things like scaffolding systems, NuGet, and T4 templates. Or should we just give the project its rightful and respectful send off as its had a good life and has outlived its usefulness.For myself, the answer is, keep it.I've spent the last couple of years doing agile engineering coaching and architecture and from my experience, I can tell you, there are a lot of shops out there that would benefit from having Tree Surgeon as a viable product.  Many would benefit simply from having the software engineering information that is embedded in the tree surgeon site be floating around their conversation.Little things like, keep all of your software needed to run the build, with the build in the version control system.Have your developers and the build system using the same build.Have a one-touch buildSeparate your code from your interfacePut unit tests in first, not lastI've seen companies with great developers suffer from the problems that naturally come from builds taking 3 and 4 hours to run.  It takes work to get that build down to 10 minutes, but the benefits are always worth it.  Tree Surgeon gives you a leg up, by starting you off with a project that you can drop into your Continuous Integration system, right out of the box.Well, it used to be right out of the box.  Today, you have to play with the project to make it work for you, but even with the issues (it hasn't been updated since 2008) it still gives you a framework, with logical separations that you can build from.If you have used Tree Surgeon in the past, take a few minutes and drop a comment about what difference it made in your development style, and what you are doing differently today because of it.

• Installing Ubuntu along with windows 7 on shrunk partition

  - by Thabo

  I am new to Ubuntu OS and ask Ubuntu community. First this is not a duplicate question. Actually this a question which is a summery of all solutions and questions were posted in this community, related to Install Ubuntu along with Windows 7. I have bought a new Hp laptop with its original windows 7.I want to install Ubuntu along with windows 7 64 bit. I ran the Ubuntu 12.4 Desktop installation CD. But Ubuntu installer doesn't show the "along with windows 7 option"only it is showing two options. I read some questions and answers posted on this community. Specially following link Ubuntu 12.04 does not see windows already install on my computer (dual installation) I tried following thinks, I ran the terminal in live CD and tried sudo dmraid -rE command and dmraid remove command .But terminals says there is no dmraid partitions. So I tried another scenario checked my partitions with g parted.There are some partitions labeled C,HP tools,Recovery and System. C is containing windows 7 Files. So I shrank the volume of C Drive. Now I have 50000Mb of unallocated disk. I tried with Gparted to create a partition on that allocated space.It says some thing that you can't create more than four primary partition.Of course all other four partitions were created on widows are actually type of primary partition. So I went back to Windows 7 and tried to create a new volume on unallocated space.But unfortunately it says,If i create a new volume it will be the type of Dynamic partition.It says we cant boot another OS from that partition. So i cancelled that step. Now i have 50000Mb unallocated space but how can i install Ubuntu on that partition without harming the existing Windows 7? Because still I have only two options: Erase and install Ubuntu. Try something else. (I can see my unallocated space by going to "something else" option.)

• Using a permutation table for simplex noise without storing it

  - by J. C. Leitão

  Generating Simplex noise requires a permutation table for randomisation (e.g. see this question or this example). In some applications, we need to persist the state of the permutation table. This can be done by creating the table, e.g. using def permutation_table(seed): table_size = 2**10 # arbitrary for this question l = range(1, table_size + 1) random.seed(seed) # ensures the same shuffle for a given seed random.shuffle(l) return l + l # see shared link why l + l; is a detail and storing it. Can we avoid storing the full table by generating the required elements every time they are required? Specifically, currently I store the table and call it using table[i] (table is a list). Can I avoid storing it by having a function that computes the element i, e.g. get_table_element(seed, i). I'm aware that cryptography already solved this problem using block cyphers, however, I found it too complex to go deep and implement a block cypher. Does anyone knows a simple implementation of a block cypher to this problem?
