• Does the Frontier Kernel have a future?

  - by pbreitenbach

  Whatever you think about Dave Winer, Frontier is an incredible piece of software. It includes quite a few advances that have yet to be surpassed: the object database, the database viewer, the scripting environment, the hierarchical-including website generation scheme, the elegant scripting language, the mixing of scripts and compilation, rapid prototyping, built in web server, simple debugger, cross-platform, simple UI, etc. My question: Dave turned Frontier over to open source and there is a Frontier Kernel project. However it is fairly quiet. Does Frontier have a future from here?

• Display On-Screen Television Graphics During Live Broadcasts

  - by ServAce85

  How and with what software do major television companies display on-screen graphics during their programs? For example: On ESPN, how do they produce the news ticker on the bottom (both graphically and from a source code point of view), create and display the scores of sports, and update and show selected stats on the fly? I've looked everywhere I can think of to find the answer, but I am at a loss. That's where you guys (and girls) come in. I hope you can help shed some light on this subject for me. Thanks in advance.

• Management Studio default file save location

  - by jayrdub

  Open a new query window. Write some SQL. Save the script, the Save File As dialog box opens - but always to the same default location in the Profiles directory. Is there any way to set my default file location? ...Like I used to do with apps from the 1980s? Under Tools|Options a default location can be specified for query results. I need the same thing for new queries (the text editor). Tried changing locations in the Registry but SSMS just overwrote my changes. Any suggestions? (I saw this unanswered question at http://www.eggheadcafe.com/software/aspnet/30098335/management-studio-default.aspx and I had same exact question so I just reposted it here)

• SDL_BlitSurface() not displaying image?

  - by Christian Gonzalez

  So I'm trying to display a simply image with the SDL library, but when I use the function SDL_BlitSurface() nothing happens, and all I get is a black screen. I should also note that I have the .bmp file, the source, and the executable file all in the same directory. //SDL Header #include "SDL/SDL.h" int main(int argc, char* args[]) { //Starts SDL SDL_Init(SDL_INIT_EVERYTHING); //SDL Surfaces are images that are going to be displayed. SDL_Surface* Hello = NULL; SDL_Surface* Screen = NULL; //Sets the size of the window (Length, Height, Color(bits), Sets the Surface in Software Memory) Screen = SDL_SetVideoMode(640, 480, 32, SDL_SWSURFACE); //Loads a .bmp image Hello = SDL_LoadBMP("Hello.bmp"); //Applies the loaded image to the screen SDL_BlitSurface(Hello, NULL, Screen, NULL); //Update Screen SDL_Flip(Screen); //Pause SDL_Delay(2000); //Deletes the loaded image from memory SDL_FreeSurface(Hello); //Quits SDL SDL_Quit(); return 0; }

• Erlang on a JVM/CLR

  - by Fortyrunner

  I've just started reading Joe Armstrongs book on Erlang and listened to his excellent talk on Software Engineering Radio. Its an interesting language/system and one whose time seems to have come around with the advent of multi-core machines. My question is: what is there to stop it being ported to the JVM or CLR? I realise that both virtual machines aren't setup to run the lightweight processes that Erlang calls for - but couldn't these be simulated by threads? Could we see a lightweight or cutdown version of Erlang on a non Erlang VM?

• Deploying Multiple Environments in Spring-MVC

  - by jboyd

  Currently all web apps are deployed using seperate config files: <!-- <import bean.... production/> --> <import bean... development/> This has disadvantages, even if you only need to swap out one config file, that I'm sure everyone is familiar with (wondering what just deployed without searching through XML is one of them) I want to add Logging to my application that basically says 'RUNNING IN PRODUCTION MODE', with a description of the services deployed and what mode they are working in. RUNNING IN PRODUCTION MODE Client Service - Production Messaging Service - Local and so on... Is this possible in Spring using a conventional deployment (putting a war on a server)? What other things do people do to manage deployments and software configurations? If not, what other ways could you achieve something similar?

• java System.nanoTime is really slow. Is it possible to implement a high performance java profiler?

  - by willpowerforever

  I did a test and found the overhead of a function call to System.nanoTime() is at least 500 ns on my machine. Seemed that it is very hard to have a high performance java profiler. For enterprise software, suppose a function takes about 350 seconds and has 12,500,000,000 times of method calls. Therefore, the number of calls to System.nanoTime() is: 12,500,000,000 * 2 = 25,000,000,000 (one for start timestamp, one for end timestamp) And the overhead of System.nanoTime in total is: 500 ns * 25,000,000,000 = 500 * 25000 s = 12500000s. Note: all data from real case. Any better way to acquire the timestamp?

• Embed remote desktop in browser

  - by Shaun_web

  I would like to embed a Remote Desktop session within my browser. I must use remote desktop because my clients can't install any additional software on the server. Here are some problems that I can already foresee: 1) I believe that I can embed an RDP ActiveX control, but then all I could support is IE. And even then, IE lockdown may forbid ActiveX controls. 2) I don't know anything about Apple computers, but I presume that they don't inherently run RDP? 3) I think there are ways to run RDP through a Java control. I don't have experience to know if this is a good or bad idea. I suppose that Java may even be disabled on some browsers, but don't know if this is a common case? So, what options have I got here to make this work reliably? I presume that I may need some default options (ie ActiveX), and then some fallback options (ie Java), and code to identify the correct option each time.

• jqueryui progress bar options like transparency and text

  - by cf_PhillipSenn

  Can I have text in the background of a jQuery UI progress bar? You know the kind I'm talking about don't you? The kind that where color:white because the progress bar is over it, and color:black because the progress bar hasn't reached it yet. I think I've seen that type of effect while installing software. Also, what about a background-image, which works, except that it is totally covered up by the progress bar? I'd like for the progress bar itself to be a little bit transparent.

• Performance statistics hooks

  - by tinny

  Lets be honest, most software that developers produce has quite modest performance requirements. E.g. Systems perhaps serving 100's of requests per second, if that. But lets assume for a moment (or even dream) that you where perhaps involved in the "next big thing" (whatever that means) and you wanted to put some sort of performance statistics logging in place to help you out when all those users come flying in. Performance statistics logging, how would you approach this requirement? Perhaps you would use some sort of generic framework for this? Or roll your own solution? What would you log? How granular? Or would you not even bother putting anything in place and rather deal with this issue when it actually became an issue? It would be really interesting to hear your thoughts on this topic.

• Tutorial for texture mapping a map onto an Open GL ES sphere?

  - by hotpaw2

  I'm not looking for a library or even open source code. I want to learn how to do this on my own. Where do I start to find an online tutorial, a book chapter, or other educational material for generating a polygonal model of a 3D sphere suitable for feeding to Open GL ES on an iPhone, and then mapping the polygons to some sort of 2D map data so I can texture map the sphere? Is there some sort of software tool (blenders? mayan?) with a tutorial on how to do generate this data? Where is the best place to start?

• Will GTK's pango and cairo work well in Cocoa and MFC applications.

  - by Lothar

  I'm writing a GUI program and decided to go native on all platforms. But for all the stuff i need to draw myself i would like to use the same drawing routines because font and unicode handling is so difficult and complex. Do you see any negative points in useing Pango/Cairo. Well on MacOSX i havent succeded installing Pango/Cairo yet. Looks like a bad Omen. I would also like to hear about the performance penality. The first time i looked at Pango i thought, yes thats the reason why Software is still getting despite better hardware.

• How to release a simple program

  - by Zenya

  What is the best practice for releasing a simple software? Suppose I created a very small simple and useful program or a tool and would like to share it with everyone by uploading it to my web-site. Do I need a license and which one? (I read http://www.gnu.org/ and http://www.fsf.org/ but still cannot decide - there are too many of them.) Do I need to put somewhere a copyright and what is the basic principles of creating "Copyright" string? How can I make a user, who is going to download and install my program, to believe that my program doesn't contain viruses or a malicious code?

• Remote DocumentRoot in Apache gives a 404

  - by kshouler

  I have the following specified in my httpd.conf, but I get a 404 when attempting to connect to the server from another machine. If I set the docroot to the default htdocs directory, everything works fine. (note.. I've also tried replacing the "//storage/data1" part of the path with the network drive letter "U:") ServerRoot "C:/Program Files/Apache Software Foundation/Apache2.2" DocumentRoot "//storage/data1/Engineering/Product Development" <Directory "//storage/data1/Engineering/Product Development"> Options Indexes FollowSymLinks AllowOverride None Order allow,deny Allow from all </Directory>

• Are there any open-source / free site analytics solutions that are intranet deployable?

  - by Richard Nichols

  There are plenty of statistics/analytics providers for Internet deployed software (e.g. Google Analytics), but I'm looking for an analytics tool to integrate into a LAN/intranet based web application. I'm aware of AWStats, but I'd prefer something with a design similar to Google Analytics, where a Javascript callback can be embedded into the app and call back to an analytics server. This doesn't require any sort of extra application server configuration and access to run. I'm thinking there's nothing available that isn't proprietary / pay-for, but I'd love to be told I'm wrong!

• How do negated patterns work in .gitignore?

  - by chrisperkins

  I am attempting to use a .gitignore file with negated patterns (lines starting with !), but it's not working the way I expect. As a minimal example, I have the folllowing directory structure: C:/gittest -- .gitignore -- aaa/ -- bbb/ -- file.txt -- ccc/ -- otherfile.txt and in my gitignore file, I have this: aaa/ !aaa/ccc/ My understanding (based on this: http://ftp.sunet.se/pub//Linux/kernel.org/software/scm/git/docs/gitignore.html) is that the file aaa/ccc/otherfile.txt should not be ignored, but in fact git is ignoring everything under aaa. Am I misunderstanding this sentence: "An optional prefix ! which negates the pattern; any matching file excluded by a previous pattern will become included again."? BTW, this is on Windows with msysgit 1.7.0.2.

• Is it possible to use HTTPS certificates for licensing?

  - by Ton van den Heuvel

  I am working on an application with multiple clients and a server running various web-services for the clients. To implement licensing I am thinking about using HTTPS as a protocol for the web-services using certificates that are issued by our company. By influencing the expiration date of a certificate for a client we can prevent them from using our software after their license term. It this possible and does it make sense to you? Additional information: I am planning on using Qt/C++ for the clients, and the Twisted framework for the web-services.

• First programming language: PHP, Ruby, Python?

  - by Victor

  I've been a Web developer for over 5 years and am looking to start building more complex Web apps. Currently, I know HTML/CSS/Javascript but I feel it's time to start learning something else. I work with a lot of applications based on PHP. I created a vBulletin forum on my own time and I would definitely want to build off of that since it has gained a bit of popularity. I also work with Wordpress quite often. All of the software I work with tends to be based on PHP but I hear a lot of people say Ruby or Python is better. Since I'm starting out, I really don't care which one I learn but I want to start right. Any recommendations for someone with HTML/CSS/Javascript knowledge but wants to branch out?

• Using a Kanban board per developer

  - by grimus

  I have been trying to get our software department to adopt some kind development process methodolgy. We only have 9 developers, and about as many projects. Currently, we can only be described as chaotic. Or perhaps 'crisis driven development' as I've seen another SO user call it. Using Kanban seems like a it could be a good fit for us. So I've discussed it with everyone else, everyone thought it sounded good. But when we discussed how the board(s) should be arranged, everyone wanted to do one board per person. Now, I've never tried Kanban, or any methodology really, but it feels like having each person managed on their own board would negate the benefits a Kanban process is supposed to provide. This notion makes me sad, and want to say 'ho-hum let's scrap this whole idea.' Do you think implementing a Kanban board per developer can be worthwhile?

• Transferring Data Directly between 2 Connections in Indy (TIdContext)

  - by killercode

  ive a sever running TIdTCPServer, and Client Using Web Browser (or any other software) to Communicate, i dunno the protocol, but what im trying to do is to Send The Data between the client and another Connection (Both Connected to the same TIdTCPServer) for example the data sent by the first client is transmitted to the second client, and the data sent by the second client is transmitted to the first client, like a proxy (i cant really use a proxy server since its just this one condition) and the TIdTCPServer should still be receiving other clients and processing their data. i stumbled upon the first line of code, since TIdContext.Connection.Socket.ReadLn requires a Delimiter, and the Client's Protocol is unknown to the server. any ideas? thanks.

• Why is autorelease especially dangerous/expensive for iPhone applications?

  - by e.James

  I'm looking for a primary source (or a really good explanation) to back up the claim that the use of autorelease is dangerous or overly expensive when writing software for the iPhone. Several developers make this claim, and I have even heard that Apple does not recommend it, but I have not been able to turn up any concrete sources to back it up. SO references: autorelease-iphone Why does this create a memory leak (iPhone)? Note: I can see, from a conceptual point of view, that autorelease is slightly more expensive than a simple call to release, but I don't think that small penalty is enough to make Apple recommend against it. What's the real story?

• How to change the BlackBerry volume, or mute it?

  - by devguy

  My current code is this: int volume = Alert.getVolume(); // reads 100 Alert.setVolume(0); It DOESN'T change the volume setting, like it would be supposed to do :( Even calling Alert.mute(true) doesn't produce any good effect. Audio.setVolume(0) also doesn't work! I'm running this on a Curve 8310. I have another software installed though that successfully manages to lower the volume setting a lot...so I suppose I'm doing something wrong. Any idea?

• How many layers is too many?

  - by Nathan

  As I have been learning about software development the last 2 years the more I learn, it seems the more gray areas I am running into. One gray area I have issues with right now is trying to decide how many layers an application should have. For example, in a WPF MVVM application what fashion of layering is ok? Is the following too separated? When I mention layering I mean creating a new class library for each layer. Presentation (View) View Model Business Layer Data Access Model Layer Utility Layer Or for a non MVVM application is this too separated? Presenation Business Data Access Model Layer Utility Layer Is acceptable to run layers together and just create folders for each layer? Any coloring of this gray area would be appreciated.

• Where to learn about HTTP?

  - by razass

  I am fluent in HTML and PHP and slowly learning JavaScript however I have noticed that there is a huge hole in my knowledge when it comes to understanding how web software communications actually work. I understand the flow of information across the net however I would like to learn about HTTP protocols to better understand how the data is actually sent back and forth through the internet to help me understand things like REST, HTTP Headers, AJAX requests, etc. However, I must be searching the wrong terms because I haven't been able to find a good description of HTTP protocols. Any help is appreciated to point me in the right direction. Thanks!

• How to get started with embedded systems in the airline or submarine industries?

  - by Jason

  Hi, Not 100% sure how to frame this question but here goes... I currently work as a Rails developer but want to work on more substancial / "meaty" projects and have always been very interested in embedded systems, especially systems that run on aircraft and especially submarines.....I know strange combination. I have been doing some searching & found lockheed martin produces a lot of underwater systems for various navys around the world e.g. http://www.naval-technology.com/projects/nssn/ However, there is very little information about what software is used within these systems, what OS's they use or anything else "technical", presume there is a lot of C / C++ involved but that is just a guess... so its hard to know where to even begin learning what is required to potential work in these areas. Just wondering if anyone has any experiance working with or more information about embeddeed systems in either the airline (onboard flight systems) or especially submarine systems? Thanks!
