• Python: How to quit CLI when stuck in blocking raw_input?

  - by christianschluchter

  I have a GUI program which should also be controllable via CLI (for monitoring). The CLI is implemented in a while loop using raw_input. If I quit the program via a GUI close button, it hangs in raw_input and does not quit until it gets an input. How can I immediately abort raw_input without entering an input? I run it on WinXP but I want it to be platform independent, it should also work within Eclipse since it is a developer tool. Python version is 2.6. I searched stackoverflow for hours and I know there are many answers to that topic, but is there really no platform independent solution to have a non-blocking CLI reader? If not, what would be the best way to overcome this problem? Thanks

• I need guidance in building my first C# project

  - by grokker

  Hi I'm a PHP developer and I have some experience with Java. I'm trying to learn C# and my first project would be a program that starts the timer on a PC by clicking a button on another PC in the network. The problem is, I don't know where to start? What do I need to read up on? The OS for both PCs is Windows XP so they're desktop apps. I'd appreciate any help from you C# gurus. I hope my start as a C# programmer would be successful. Thank you!

• If I had to create a server farm what should I do? (how others companies work?)

  - by Michel

  I have a business idea but this is not really my field so I'm trying to understand what I'm really dealing with. I have a general understanding of how a web farm works, I'm a web developer and I understand the technology behind it, but I'm curious to know specifically how a web farm is set up and which professionals are involved. Things to consider probably are the hardware, the power supply, the software managment, the cooling system and if possible the usage of green technology/power recycling. Basically, can you explain me how a web hosting company is structured and how it works? A big question, I know, but from what I already read here about the subject a lot of you know this stuff. Thanks for your time guys!

• Android API Target Level 5 and 6 for Ubuntu

  - by Sebi

  Today i installed Ubuntu 10.4 and Eclipse Galileo. Then I downloaded the Android SDK and tried to install all packages via the Android SDK Tools. But unfortunately, only the Target Levels 3, 4, 7 and 8 were available. API Level 5 and 6 are missing. Does anybody know the reason for this? I already did a Google search and there seems to be nobody with the same problem. I also tried to restart it and nothing happens, the API Levels are still missing.

• FastObjects.NET(is an OODB from Versant) performence in Real Scenerios?

  - by Lalit

  FastObjects.NET Saves the whole class object(if marked with attribute Persistent) at once in file system(using serilization or similar technology). They are promissing that it is even faster then normal SQL DB approach. My team also thought it is better and faster to save the whole object once instead of each field one by one. Defination of their website: FastObjects .NET 10.0 fully conforms to the Microsoft.NET 2.0 framework. Tightly integrated with Visual Studio 2005, it offers a developer-friendly, object-oriented alternative to a relational database for .NET persistence. I want to have your experiences of using FastObjects in production scenerio? They are promising for Indexing/Transaction/clustoring/replication.

• android localization: Is it a good practice to have only needed resource to put in localized folder?

  - by MobileDev123

  Hi, My application has 4 languages in it. However only one module needs to be localized out of 5, This module has 4 layout files and some images, remaining files can be there in default layout folder and drawable folders. My question is : is it good practice to put only needed files in localization folders, if I leave other files in its respective folders and don't copy them in translation folders, does my application throw NullPointerException when my application runs in other language? and Does android market have any size limit? (Also being a BB developer,AFAIK they do not allow OTA, if the application size grows more than 3 mb) [In case i need to copy the layout and image files]. Note about NullPointerException : it throws in string if you omit some string in localization and application runs in that particular locale. Thanks

• What ever happened to Java and Sun?

  - by leeand00

  What happened to Java and Sun? The community surrounding them had some of my favorite tools and software to develop with. The Java platform anyway, still looked like it had some promise to it: Groovy and Grails. Why does all of this seem to be going the way of the dodo lately? (Yes, I know their stock price is dropping badly.) Is it just the economy? Or did the lack of cohesion (i.e., not settling on a framework) among the community finally lead to its demise?

• How do you install cocos2d-iphone on the Mac?

  - by johnfromberkeley

  There are no good instructions for installing cocos2d for iPhone on the mac. I downloaded the current build from git, a folder called "cocos2d-iphone-0.99.1". i put this folder in /Developer/Libary. Q: is this right? I tried running the file called "install_template.sh". it said the templates were already installed. Instead, I manually dragged the templates folders where they belong, and they ~do~ appear in the XCode's "New Project" dialog. When I create a new cocos2d project, I see all these red links for project files, instead of the regular black links. When I try to open them in the finder, nothing happens. I can tell that something is not linked. Can someone please help walk me through this? Thanks!

• how to find which libraries to link to? or, how can I create *-config (such as sdl-config, llvm-con

  - by numeric

  Hey, I want to write a program that outputs a list of libraries that I should link to given source code (or object) files (for C or C++ programs). In *nix, there are useful tools such as sdl-config and llvm-config. But, I want my program to work on Windows, too. Usage: get-library-names -l /path/to/lib a.cpp b.cpp c.cpp d.obj Then, get-library-names would get a list of function names that are invoked from a.cpp, b.cpp, c.cpp, and d.obj. And, it'll search all library files in /path/to/lib directory and list libraries that are needed to link properly. Is there such tool already written? Is it not trivial to write a such tool? How do you find what libraries you should link to? Thanks.

• Wrapping C/C++ inside Java

  - by Ashwin

  I develop applications/programs in C/C++. I am more versed in these two languages and love being a C++ developer. I am wondering how to create a Java program that contains all my C++ code. I mean, I would like to wrap all my C++ code (that is already developed) inside Java class. But clueless how to do it. Please post your responses or methods/steps on integrating C++ inside Java. (using JNI is the way, but I could not figure it out on www how to use it) FYI, I use Eclipse IDE to develop. How and what packages should I include in my project workspace?

• Why should i POST data rather then GET?

  - by acidzombie24

  I know you dont want to POST a form with a username and password where anyone could use the history to see or situations where repeat actions may not be desired (refreshing a page = adding an item to a cart may not be desired). So i have an understanding when i may want to use one over the other. But i could always have the server redirect the url after a get to get around the cart problem and maybe most of my forms will work perfectly fine with get. WHY should i use POST over get? I dont understand the benefits of one over the other. I do notice post doesnt add data to the history/url and will warn you about refreshing the page but those are the only two differences i know of. Why as a developer might i want to use one over the other?

• Metro style apps with Html and C#

  - by labroo

  According to this slide http://geekswithblogs.net/images/geekswithblogs_net/technetbytes/windows-8-platform-tools.jpg Does it mean I have to use XAML view with C# if I want to develop a metro styled application? Can I use a HTML/JS/CSS - C# combination with event handlers and all? Something like ASP.NET Webforms/MVC . I know it is not the same client server architecture, but since metro styled apps support HTML/JS, I was wondering. I can use Win-JS. But can I rather write C# than Javascript, and use HTML rather than XAML?(I dont know XAML and I like C#) All the C# samples I found online use XAML.

• How to decrease front end development time in a company/team environment?

  - by metal-gear-solid

  How to decrease front end development time in a company/team environment? My company is asking to suggest idea to make front end development process faster? Some points I realized main problem is client never provide right information at first time and many front end developer works on same project on same CSS so everyone makes his own method sometimes. It increase time of process. Graceful degradation and progressive enhancement both takes time to think and development. should we think about it? it increase the project cost. How to judge time estimation by just seeing a PSD for to make PSD in Cross browser Compatible XHTML CSS. Most of the time I always give less time then then takes more time. Any other suggestions to improve work efficiency in a team (50 people) environment?

• Project-wide additional library paths -- MSVS2008

  - by sacamano

  Hi there. I'm setting up a VC++ project in MS Visual Studio 2008 that'll be used by several people. I wanted to keep things as simple as possible so I've set up Additional Include Directories via the Project properties. I've also set up additional library files via Tools - Options - Projects and Solutions - VC++ Directories. However, my issue is that I really need to set up Additional library PATHs, because I am using an SDK which does inline linking of libraries. I could just tell each one of the participants to manually add the library path to their MSVS2008 environment, but it would be handy if I could integrate the RELATIVE library path in the project itself.

• Opening up TCP Sockets in j2ee Webapplication

  - by Gvenez

  Hello, We have to communicate with a C++ component from a J2ee web application and my proposal involved using JMS server to communicate with the C++ component which is located on other machine. However the developer of the C++ component wants me to open up TCP/IP sockets from the webapplication and communicate over XML. My view is that socket programming in web application is error prone and will not scale well since there is a limited amount of sockets that can be opened up. Please let me have your architecture/design preference on using JMS vs TCP/IP sockets. Thank you

• How do I change the number of thumbnails seen in the Android sample Home application?

  - by Todd

  I am working with the sample Home application project on http://developer.android.com/resources/samples/Home/index.html I've added another value to the THUMBS_IDS and IMAGE_IDS Integer arrays in the Wallpaper class for a total of four wallpaper options. When I run the application with Device API version 7, Skin: HVGA, hw.lcd.density: 160, in portrait layout, the fourth wallpaper option is not shown. I need to use the directional keys in the emulator to see the 4th wallpaper option, because the first option is centered. I have modified only the wallpaper.xml file with a variety of android:layout_* options with no success at this point. How do I show all four of my wallpaper options?

• Should we develop code on a local machine in a VLAN?

  - by red tiger

  Because of security reasons, we will not be able to use IIS on our local machines. I'm sure that many of you have faced the same problem, so how did you solve it? Here are the options that we're looking at: Create a VLAN that is isolated from the network for development. This will allow us to use any software, including IIS, that we want. A disadvantage is testing Web services with external organizations, which can be overcome by using stubs. Not use a VLAN and use only the ASP.NET Development Server that comes with Visual Studio, and then deploying that code to the development server. This has the disadvantage of not being able to replicate the production environment during local development. In addition, at least one developer needs IIS for GIS development, so he couldn't develop locally. Thank you for comments or suggestions that you may have!

• Authorization/Licensing of Webservice

  - by Burhan

  I have developed a web service which accepts the login credentials from the XML message passed to it. I have concerns over this method as the developer who consumes the service can easily share the login credentials and my service can be called from some other application that uses the same credentials. Is there any way that I can issue a 'license' to some specific applications? So that, even if credentials are shared among the consuming apps, only authorized ones can successfully consume the service. P.S: I thought about implementing IP restrictions but that doesn't serve the purpose as we may have different applications installed on a same server (we do have such a scenario implemented).

• In Visual Studio 2010, intellisense isn't showing for long method signatures

  - by sohtimsso1970

  The problem is exactly as asked in the question title. When I'm typing in the text editor and referencing a public method that has a long signature (lots of parameters, usually 10 or more) the intellisense just stops working. It will sometimes flicker; other times it will not show at all. Only seen this happen with C#, but I don't use anything else. It might happen in VB too. Don't know. Anyone else seeing this? I've Googled for an hour but can't seem to iron it out. I've restarted VS, rebooted the machine, enabled/disabled intellisense in Tools - Options. NOTHING works.

• How to print all rows in one page with Crystal Reports

  - by Matt

  I am using Crystal Reports 2011. I am totally new to crystal reports and reporting tools in general. I just added my data fields to the details section, but instead of showing all the rows in one page, a new page is created for each row. I did not use any grouping or change the section paging settings. This only happens for a blank report, when using the report wizard it works fine, but I can't see the difference between what I did and what the report wizard did.

• Best practices for packaging resources (jpg's, sound, video) in an iPhone app?

  - by Mel

  I'm a newb iPhone developer writing an app that has several large JPGs and sound files. Everything works ok if I drag these non-code resources into my project. But I am wondering if this is the right way to package my app. In Windows development, I would create a "resource DLL" that keeps the .exe size small. What is the equivalent for iPhone? I think I should be creating a "bundle" - can someone please give me some pointers to using these and how to link them into my main project? Thanks!

• How exactly can Python compliment your C# skills for windows based development?

  - by JL

  I'm looking for a fun challenge, and am thinking about learning Python. I've heard really good things about the language. My question is, how (if at all) can Python compliment the skills of a typical C# developer working mainly with MS technologies on a Windows Platform. Some examples of typical C# dev on windows would be (SOA applications, web applications, windows services, automation, xml handling) Surely there must be some scenarios where knowing Python would help you get certain tasks done quicker or more efficiently than using traditional C# / MS technologies. If you know of any specific scenarios, then please share. And lastly should this question be a community wiki?

• How can I create a sample SQLLite DB for my iPhone app?

  - by Dr Dork

  I'm diving in to iPhone development and I'm building an iPhone app that uses the Core Data framework and my first task will be to get the model setup with a few that will display it. Thus far, I have the model defined and my Managed Object Files created, but I don't have a database with any sample data. What's a quick way to create a DB that conforms to my schema? Are there any tools that can generate a sample DB using my schemas? Is there a good tool I can use to directly manipulate the data in DB for testing purposes? Thanks in advance for your help! I'm going to continue researching this question right now.

• Export from a standalone database to an embedded database.

  - by jdana

  I have a two-part application, where there is a central database that is edited, and then at certain times, the data is released and distributed as its own application. I would like to use a standalone database for the central database (MySQL, Postgres, Oracle, SQL Server, etc.) and then have a reliable export to an embedded database (probably SQLite) for distribution. What tools/processes are available for such an export, or is it a practice to be avoided? EDIT: A couple of additional pieces of information. The distributed application should be able to run without having to connect to another server (ex: your spellchecker still works even you don't have internet), and I don't want to install a full DB server for read-only access to the data.

• Web GUI frameworks for Phone development

  - by Runner

  I looked already and could't find anyting good. So a question is, are there any good web frameworks that would allow to easily develop GUI for the majority of high end phones? By this I mean It would have to work the same on majority of high end phones (forget the low cost ones) It would have to simplify the development and hide the ugly details from developer Clear design and good documentation. Also some stability on the market. The focus in on good looking and easy to make GUI. Javascript is only a plus. So basically I am looking for something like jQuery or maybe ExtJS for phone development. EDIT: It would be a big plus if it could be consumed in Delphi EDIT 2: If it was not clear, I am looking for a web base solution. So the target is HTML output and not native code.
