  • Installed Ruby 1.9.2 but new gems won't create scripts into /usr/bin

    - by karatedog
    I had previously ruby 1.8 on my Ubuntu 10.10, which I removed through Synaptics. Then I have installed ruby 1.9.1 also via Synaptics (which is then saying that itself is version 1.9.2). Then I installed ruby-debug19 and rspec gems with sudo gem install ruby-debug19 rspec However I can't start rdebug or rspec, but I can invoke the debugger from inside my ruby script, so the debugger is working. I inspected the starting scipts rdebug and rspec and then I realized that they are still old scripts back from ruby1.8 time. In other worlds, the current 1.9 install of these gems haven't created the starting scripts anywhere. What is the easiest solution for a lazy soul like me? It looks like removing-reinstalling ruby 1.9.2 won't help, and installing these gems over and over againg won't create the starting scripts.

  • Running a .bash file in Eclipse

    - by Anne Ambe
    I know this is really an Eclipse issue but I can't seem to login in their forum. I am running eclipse juno for some c/c++ development.However, I wrote a .bash script that initiate the entire program.As input argument to this script, I have a a configuration file which is one directory lower than the .bash file. In terminal I just do: ./startenb.bash ./CONF/ANNE it runs just fine. How can I configure the external tools in eclipse to take this file path as input argument? Any help or old thread vaguely addressing this issue is highly welcome.

  • Do I need to contact a lawyer to report a GPL violation in software distributed on Apple's App Store?

    - by Rinzwind
    Some company is selling software through Apple's App Store which uses portions of code that I released publicly under the GPL. The company is violating the licensing terms in two ways, by (1) not preserving my copyright statement, and not releasing their code under the GPL license and (2) by distributing my GPL-licensed code through Apple's App Store. (The Free Software Foundation has made clear that the terms of the GPL and those of the App Store are incompatible.) I want to report this to Apple, and ask that they take appropriate action. I have tried mailing them to ask for more information about the reporting process, and have received the automated reply quoted below. The last point in the list of things one needs to provide, the “a statement by you, made under penalty of perjury,” sounds as if they mean some kind of specific legal document. I'm not sure. Does this mean I need to contact a lawyer just to file the report? I'd like to avoid going through that hassle if at all possible. (Besides an answer to this specific question, I'd welcome comments and experience reports from anyone who has already had to deal with a GPL violation on Apple's App Store.)

  • Fresh install 12.04 Performance & Stability: SONY VPCCW2S1E

    - by George Katsanos
    just yesterday I installed 12.04. Is it normal that installing a package (Chrome for example) takes 5 to 10 minutes (compared to Windows 7 for example which takes 2 or 3)? (with end result: installation failed) Otherwise is it normal that while the system is doing some installation,extracting packs and so on, other applications often become unresponsive? Sidenote: I don't care about fancy desktop effects, I installed ubuntu to go on and experiment with web servers, memcache, Varnish and git/svn. So basically I plan to do lots of console-only operations. My surprise was also the difference of stability compared to an old FreeBSD installation I had on a dinosaur P3 550Mhz :) (I am on a SONY VPCCW2S1E) (I guess it might have to do something with my problems?)

  • Poor mobile performance when running from Eclipse

    - by Yajirobe_LOL
    So after weeks of thinking my rendering code was bad, I accidentally discovered the following: Running my game on a Nexus S From Eclipse (Debug as - Android application): 12fps From the device while still attached to USB (getting log info in Eclipse still): 24fps From the device while not attached via USB: 56fps I was wondering if anyone else has issues like this? I mean, the problem really isn't a problem since the final release build will likely have good performance, but for the time being I don't want to have to keep (un)plugging my device in and out when testing code all day long. Is there some remedy for this or does anyone have any input/advice? Thanks.

  • Sphere-Sphere intersection and Circle-Sphere intersection

    - by cagirici
    I have code for circle-circle intersection. But I need to expand it to 3-D. How do I calculate: Radius and center of the intersection circle of two spheres Points of the intersection of a sphere and a circle? Given two spheres (sc0,sr0) and (sc1,sr1), I need to calculate a circle of intersection whose center is ci and whose radius is ri. Moreover, given a sphere (sc0,sr0) and a circle (cc0, cr0), I need to calulate the two intersection points (pi0, pi1) I have checked this link and this link, but I could not understand the logic behind them and how to code them. I tried ProGAL library for sphere-sphere-sphere intersection, but the resulting coordinates are rounded. I need precise results.

  • What's the most important trait of a programmer desired by peer programmers [closed]

    - by greengit
    Questions here talk about most important programming skills someone is supposed to possess, and, a lot of great answers spring up. The answers and the questioners seem mostly interested on qualities related to getting a better job, nailing some interview, things desired by boss or management, or improving your programming abilities. One thing that often gets blown over is the genuine consideration for what traits peers want. They don't much value things like you're one of those 'gets things done' people for the company, or you never miss a deadline, or your code is least painful to review and debug, or you're team player with fantastic leading abilities. They probably care more if you're helpful, are a refreshing person to talk to, you're fun to program in pair with, everybody wants you to review their code, or something of that nature. I, for one, would care that I come off to my peers as a pleasurable programmer to work with, as much as I care about my impression on my boss or management. Is this really significant, and if yes, what are the most desirable traits peers want from each other.

  • New JDeveloper/ADF book hits the bookshelves

    - by Grant Ronald
    I've just received a nice new copy of Sten Vesterli's book Oracle ADF Enterprise Application Development - Made Simple.  I was one of the technical reviewers of the book but I'm looking forward to be able to read it end-to-end in good old fashioned book format this coming week. The book bridges the gap between those existing books that describe Oracle ADF features, and real world ADF development.  So, source control, bug tracking, estimating, testing, security, packaging etc are all covered.  Of course, every project and situation is different so the book could never supply a one-size-fits-all guide, but I think its a good addition to your ADF bookshelf.  I'll hopefully post a full review in the coming weeks. Oh, and congratulations Sten,  having gone through the pain of writing my own ADF book, I take my hat off to anyone who goes through the same journey!

  • Scheduling Jobs in SQL Server Express

    As we all know SQL Server 2005 Express is a very powerful free edition of SQL Server 2005. However it does not contain SQL Server Agent service. Because of this scheduling jobs is not possible. So if we want to do this we have to install a free or commercial 3rd party product. This usually isn't allowed due to the security policies of many hosting companies and thus presents a problem. Maybe we want to schedule daily backups, database reindexing, statistics updating, etc. This is why I wanted to have a solution based only on SQL Server 2005 Express and not dependent on the hosting company. And of course there is one based on our old friend the Service Broker.

  • Beginning with first project on game development [closed]

    - by Tsvetan
    Today is the day I am going to start my first real game project. It will be a Universe simulator. Basically, you can build anything from tiny meteor to quazars and universes. It is going to be my project for an olympiad in IT in my country and I really want to make it perfect(at least a bronze medal). So, I would like to ask some questions about organization and development methodologies. Firstly, my plan is to make a time schedule. In it I would write my plans for the next month or two(because that is the time I have). With this exact plan I hope to make my organisation at its best. Of course, if I am doing sth faster than the schedule I would involve more features for the game and/or continue with the tempo I have. Also, for the organisation I would make a basic pseudocode(maybe) and just rewrite it so it is compilable. Like a basic skeleton of everything. The last is an idea I tought of in the moment, but if it is good I will use it. Secondly, for the development methodologies, obviously, I think of making object-oriented code and make everything perfect(a lot of testing, good code, documentation etc.). Also, I am going to make my own menu system(I read that OpenGL hasn't got very good one). Maybe I would implement it with an xml file, holding the info about position of buttons, text boxes, images and everything. Maybe I would do a specific CSS for it and so on. I think that is very good way of doing the menu system, because it makes the presentation layer separate of the logic. But, if there is a better way, I would do it the better way. For the logic, well, I don't have much to say. OO code, testing, debuging, good and fast algorithms and so on. Also, a good documentation must be written and this is the area I need to make some research in. I think that is for now. I hope I have been enough descriptive. If more questions come on my mind, I will ask them. Edit: I think of blogging every part of the project, or at least writing down everything in a file or something like that. My question is: Is my plan of how to do everything around the project good? And if not, what is necessary to be improved and what other things I can involve for making the project good.

  • Approach on working with many programmers on one module/feature

    - by Panoy
    How can 2 or more developers code a certain feature/module of a software? Let's assume that the module is big and feature rich. How would they prevent each other from overlapping their code? Say, we have the same method but is implemented in a different way. Do you think it might be better to have one focused at a specific feature only? Is a version control system like Git would help solve the problem? Is it correct that it allows developers to have these "branches" and then merge it later on? What's your take on this?

  • What are best practices when giving a presentation to programmers?

    - by blunders
    I've watched 50 plus presentations on programming topics, although most have been online; example, Google Tech Talks -- and have ad-hoc experience on what formats work for programmers, or practices to take into account when presenting to a group of programmers. That said, I'm open to any suggestions, but here's some topic of the top of my head: Programming Jokes, Images, etc. Posting Code for download Contact Info Collecting feedback Presenting Code on Screen If it matters, in this case -- I'm giving a presentation on using a scripting language to extract, transform and load data to a local user group who's focus is the scripting language; Ruby in this case. Questions, feedback, requests -- just comment, thanks!!

  • Help with creating symbolic link

    - by user1737794
    I'm a little bit confused with how the symbolic links work. I hope someone can guide me in the right direction. I want to put a demo online from our software, which normally only runs locally on a Mac Mini. So I put all the files in the var/www from my Ubuntu 12.04 server installation. There are a lot of hardcoded links in the software which point to "/Applications/XAMPP/xamppfiles/htdocs/narrowcasting" Of course I can change all these code on my html/php files in /var/www, but that would be quite annoying. I hope I can fix this by creating a symbolic link. For example I have a directory called thumb in /var/www/thumb. The php code is trying to put a image in /Applications/XAMPP/xamppfiles/htdocs/narrowcasting/thumb. Can anyone give me a tip how to achieve this with a symbolic link? Thanks in advance.

  • Integration Patterns with Azure Service Bus Relay, Part 2: Anonymous full-trust .NET consumer

    - by Elton Stoneman
    This is the second in the IPASBR series, see also: Integration Patterns with Azure Service Bus Relay, Part 1: Exposing the on-premise service Part 2 is nice and easy. From Part 1 we exposed our service over the Azure Service Bus Relay using the netTcpRelayBinding and verified we could set up our network to listen for relayed messages. Assuming we want to consume that service in .NET from an environment which is fairly unrestricted for us, but quite restricted for attackers, we can use netTcpRelay and shared secret authentication. Pattern applicability This is a good fit for scenarios where: the consumer can run .NET in full trust the environment does not restrict use of external DLLs the runtime environment is secure enough to keep shared secrets the service does not need to know who is consuming it the service does not need to know who the end-user is So for example, the consumer is an ASP.NET website sitting in a cloud VM or Azure worker role, where we can keep the shared secret in web.config and we don't need to flow any identity through to the on-premise service. The service doesn't care who the consumer or end-user is - say it's a reference data service that provides a list of vehicle manufacturers. Provided you can authenticate with ACS and have access to Service Bus endpoint, you can use the service and it doesn't care who you are. In this post, we’ll consume the service from Part 1 in ASP.NET using netTcpRelay. The code for Part 2 (+ Part 1) is on GitHub here: IPASBR Part 2 Authenticating and authorizing with ACS In this scenario the consumer is a server in a controlled environment, so we can use a shared secret to authenticate with ACS, assuming that there is governance around the environment and the codebase which will prevent the identity being compromised. From the provider's side, we will create a dedicated service identity for this consumer, so we can lock down their permissions. The provider controls the identity, so the consumer's rights can be revoked. We'll add a new service identity for the namespace in ACS , just as we did for the serviceProvider identity in Part 1. I've named the identity fullTrustConsumer. We then need to add a rule to map the incoming identity claim to an outgoing authorization claim that allows the identity to send messages to Service Bus (see Part 1 for a walkthrough creating Service Idenitities): Issuer: Access Control Service Input claim type: http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier Input claim value: fullTrustConsumer Output claim type: net.windows.servicebus.action Output claim value: Send This sets up a service identity which can send messages into Service Bus, but cannot register itself as a listener, or manage the namespace. Adding a Service Reference The Part 2 sample client code is ready to go, but if you want to replicate the steps, you’re going to add a WSDL reference, add a reference to Microsoft.ServiceBus and sort out the ServiceModel config. In Part 1 we exposed metadata for our service, so we can browse to the WSDL locally at: http://localhost/Sixeyed.Ipasbr.Services/FormatService.svc?wsdl If you add a Service Reference to that in a new project you'll get a confused config section with a customBinding, and a set of unrecognized policy assertions in the namespace http://schemas.microsoft.com/netservices/2009/05/servicebus/connect. If you NuGet the ASB package (“windowsazure.servicebus”) first and add the service reference - you'll get the same messy config. Either way, the WSDL should have downloaded and you should have the proxy code generated. You can delete the customBinding entries and copy your config from the service's web.config (this is already done in the sample project in Sixeyed.Ipasbr.NetTcpClient), specifying details for the client:     <client>       <endpoint address="sb://sixeyed-ipasbr.servicebus.windows.net/net"                 behaviorConfiguration="SharedSecret"                 binding="netTcpRelayBinding"                 contract="FormatService.IFormatService" />     </client>     <behaviors>       <endpointBehaviors>         <behavior name="SharedSecret">           <transportClientEndpointBehavior credentialType="SharedSecret">             <clientCredentials>               <sharedSecret issuerName="fullTrustConsumer"                             issuerSecret="E3feJSMuyGGXksJi2g2bRY5/Bpd2ll5Eb+1FgQrXIqo="/>             </clientCredentials>           </transportClientEndpointBehavior>         </behavior>       </endpointBehaviors>     </behaviors>   The proxy is straight WCF territory, and the same client can run against Azure Service Bus through any relay binding, or directly to the local network service using any WCF binding - the contract is exactly the same. The code is simple, standard WCF stuff: using (var client = new FormatService.FormatServiceClient()) { outputString = client.ReverseString(inputString); } Running the sample First, update Solution Items\AzureConnectionDetails.xml with your service bus namespace, and your service identity credentials for the netTcpClient and the provider:   <!-- ACS credentials for the full trust consumer (Part2): -->   <netTcpClient identityName="fullTrustConsumer"                 symmetricKey="E3feJSMuyGGXksJi2g2bRY5/Bpd2ll5Eb+1FgQrXIqo="/> Then rebuild the solution and verify the unit tests work. If they’re green, your service is listening through Azure. Check out the client by navigating to http://localhost:53835/Sixeyed.Ipasbr.NetTcpClient. Enter a string and hit Go! - your string will be reversed by your on-premise service, routed through Azure: Using shared secret client credentials in this way means ACS is the identity provider for your service, and the claim which allows Send access to Service Bus is consumed by Service Bus. None of the authentication details make it through to your service, so your service is not aware who the consumer is (MSDN calls this "anonymous authentication").

  • Will an Atheros AR928X work with WPA2?

    - by Tommy
    Basically I need only the answer to above question. Please think of that I am new to linux. For further explanation here is the full story: I have the following problem. My friends notebook (Vista) has got a trojan and refuses to work anymore. The Avira Rescue CD did not help either. So I tried an old (9.1) Ubuntu CD and backed up all the essential files. Since we have no Windows Install Disk we want to put Ubuntu on that notebook. But with the 9.1 version there is no WLAN. Systemtest tells me, that it finds an Atheros AR928X, but ifconfig does not show that and the network manager tells me there are no LAN/WLAN devices. So: does that work easier with the new Ubuntu version or is that network adapter a known troublemaker? And: if I get the adapter to work, will it work with the WPA2-network around here?

  • Why was Python's popularity so sudden? [closed]

    - by Eric Wilson
    Python first appeared in 1991, but it was somewhat unknown until 2004, if the TIOBE rankings quantify anything meaningful. What happened? What caused the interest in this 13 year old language to go through the roof? Is there a reason that Python wasn't considered a real competitor to Perl in its first decade of existence? Is there a reason that Python didn't continue in relative obscurity for another ten years? I personally think that Python is a very nice language, and I'm glad that I'm not the only one. But it doesn't have corporate backing or a killer feature that would explain a sudden rise to relevance. Does anyone know the story?

  • Commit Review Questions

    - by Wes McClure
    Note: in this article when I refer to a commit, I mean the commit you plan to share with the rest of the team, if you have local commits that you plan to amend/combine, I am referring to the final result. In time you will find these easier to do as you develop, however, all of these are valuable before checking in!  The pre commit review is a nice time to polish what might have been several hours of intense work, during which these things were the last things on your mind!  If you are concerned about losing your work in the process of responding to these questions, first do a check-in and amend it as you go (assuming you are using a tool such as git that supports this), rolling the result into one nice commit for everyone else.  Did you review your commit, change by change, with a diff utility? If not, this is a list of reasons why you might want to start! Did you test your changes? If the test is valuable to be automated, is it? If it’s a manual testing scenario, did you at least try the basics manually? Are the additions/changes formatted consistently with the rest of the project? Lots of automated tools can help here, don’t try to manually format the code, that’s a waste of time and as a human you will fail repeatedly. Are these consistent: tabs versus spaces, indentation, spacing, braces, line breaks, etc Resharper is a great example of a tool that can automate this for you (.net) Are naming conventions respected? Did you accidently use abbreviations, unless you have a good reason to use them? Does capitalization match the conventions in the project/language? Are files partitioned? Sometimes we add new code in existing files in a pinch, it’s a good idea to split these out if they don’t belong ie: are new classes defined in new files, if this is something your project values? Is there commented out code? If you are removing an existing feature, get rid of it, that is why we have VCS If it’s not done yet, then why are you checking it in? Perhaps a stash commit (git)? Did you leave debug or unnecessary changes? Do you understand all of the changes? http://geekswithblogs.net/wesm/archive/2012/04/11/programming-doesnrsquot-have-to-be-magic.aspx Are there spelling mistakes? Including your commit message! Is your commit message concise? Is there follow up work? Are there tasks you didn’t write down that you need to follow up with? Are readability or reorganization changes needed? This might be amended into the final commit, or it might be future work that needs added to the backlog. Are there other things your team values that you should review?

  • Should I be put off a junior role that uses an online development test?

    - by Ninefingers
    I've applied for a junior development role, or rather been found by a recruiter looking for a developer. In order to get to a telephone interview stage I've been asked to sit one of those online coding assessments. This wasn't quite what I expected. I consider myself a fairly good developer for my age and experience, but I've no illusions about being Don Knuth or anything. The test was a series of incredibly obtuse questions asking about the results of various obscure evaluations. About 30 minutes in I was thinking to myself I hadn't intended to enter an obfuscated code contest/code golf exercise. After my last telephone interview I was asked to build something. I did. That seemed fair. Go away and work this out is more my in office experience of programming than "please evaluate this combination of lambdas, filters, maps, lists, tuples etc". So I'm a little put off, to be honest. I never claimed to know the language inside out or all the little corner cases. My questions, then: Should I be put off? Why? Why not? Are these kinds of tests what I should be expecting for junior roles? Should I learn stuff exam style? That seems to be the objective of these tests, for which you are timed and not supposed to use references or books? Normally, in the course of development I have a fairly good idea of basic types, rules, flow control and whatever. Occasionally I'll come up on something I need to use a regex for and have to go and remind myself of the exact piece of syntax I need if trying what I think should work doesn't. Or I'll come up against a module I've not used before and go and look it up. For example, if I wanted to write a server using sockets in C right now, I'd probably check the last piece of code I wrote doing that (and or the various books I have) and work from there. Chances are I probably couldn't do it exactly from scratch and from memory, although I can tell you you'd need a socket(), bind(), listen() and accept() call and you might also want select() depending on whether you intend to pthread_create or not. So I know what the calls are, but not their specific parameter list. What are your experiences if you are a recruiting manager? Are you after programmers who can quote you the API or do you not mind if your programmers have a few books on their desk and google function calls every so often?

  • How to incorporate existing open source software from a licensing perspective?

    - by Matt
    I'm working on software that uses the following libraries: Biopython SciPy NumPy All of the above have licenses similar to MIT or BSD. Three scenarios: First, if I don't redistribute those dependencies, and only my code, then all I need is my own copyright and license (planing on using the MIT License) for my code. Correct? What if I use py2exe or py2app to create a binary executable to distribute so as to make it easy for people to run the application without needing to install python and all the dependencies. Of course this also means that my binary file(s) contains python itself (along with any other packages I might have performed a pip install xyz). What if I bundle Biopython, SciPy, and NumPy binaries in my package? In the latter two cases, what do I need to do to comply with copyright laws.

  • Most efficient way to rebuild a tree structure from data

    - by Ahsan
    Have a question on recursively populating JsTree using the .NET wrapper available via NuGet. Any help would be greatly appreciated. the .NET class JsTree3Node has a property named Children which holds a list of JsTree3Nodes, and the pre-existing table which contains the node structure looks like this NodeId ParentNodeId Data AbsolutePath 1 NULL News /News 2 1 Financial /News/Financial 3 2 StockMarket /News/Financial/StockMarket I have a EF data context from the the database, so my code currently looks like this. var parentNode = new JsTree3Node(Guid.NewGuid().ToString()); foreach(var nodeItem in context.Nodes) { parentNode.Children.Add(nodeItem.Data); // What is the most efficient logic to do this recursively? } as the inline comment says in the above code, what would be the most efficient way to load the JStree data on to the parentNode object. I can change the existing node table to suite the logic so feel free to suggest any changes to improve performance.

  • Building a Flash Platformer

    - by Jonathan O
    I am basically making a game where the whole game is run in the onEnterFrame method. This is causing a delay in my code that makes debugging and testing difficult. Should programming an entire platformer in this method be efficient enough for me to run hundreds of lines of code? Also, do variables in flash get updated immediately? Are there just lots of threads listening at the same time? Here is the code... stage.addEventListener(Event.ENTER_FRAME, onEnter); function onEnter(e:Event):void { //Jumping if (Yoshi.y > groundBaseLevel) { dy = 0; canJump = true; onGround = true; //This line is not updated in time } if (Key.isDown(Key.UP) && canJump) { dy = -10; canJump = false; onGround = false; //This line is not updated in time } if(!onGround) { dy += gravity; Yoshi.y += dy; } //limit screen boundaries //character movement if (! Yoshi.hitTestObject(Platform)) //no collision detected { if (Key.isDown(Key.RIGHT)) { speed += 4; speed *= friction; Yoshi.x = Yoshi.x + movementIncrement + speed; Yoshi.scaleX = 1; Yoshi.gotoAndStop('Walking'); } else if (Key.isDown(Key.LEFT)) { speed -= 4; speed *= friction; Yoshi.x = Yoshi.x - movementIncrement + speed; Yoshi.scaleX = -1; Yoshi.gotoAndStop('Walking'); } else { speed *= friction; Yoshi.x = Yoshi.x + speed; Yoshi.gotoAndStop('Still'); } } else //bounce back collision detected { if(Yoshi.hitTestPoint(Platform.x - Platform.width/2, Platform.y - Platform.height/2, false)) { trace('collision left'); Yoshi.x -=20; } if(Yoshi.hitTestPoint(Platform.x, Platform.y - Platform.height/2, false)) { trace('collision top'); onGround=true; //This update is not happening in time speed = 0; } } }

  • Disk utility running for a long time

    - by Nik
    I had a spare, old external usb hard disk which stopped working long time back due to improper removal of disk. I tried fixing it in windows (when I did not have ubuntu yet), however I couldn't fix it. So I tried formatting the disk and creating a new partition using the disk utility in ubuntu. However it seems to keep running without any indication of the progress or whatsoever. I have no idea what is happening. I have attached a screenshot below to show what I mean. As you can from the screenshot above it seems to be working on it but no indication on the progress or what it is doing. Any attempt to exit it or do any other task like safe removal or format partition leads to the the following dialog box. What should I do? Wait or restart the computer..???

  • Custom per domain CSS in Internet Explorer

    - by Damiqib
    We have an old web app, which would be much more usable if it could be visually tweaked a bit. Being in a corporate environment - IE (always using the latest version) is all I can use. Also app in question being 3rd-party - there's no way to change it's own CSS files. Is there a way to use per domain injected custom CSS in internet Explorer. Let's say I want to change the background-color of domain http://oldapp.localintranet/ - is there any way to make this happen? Place to put a custom.css-file? With an add-on/extension?
