• Recommendation for tool/framework that follows the naked objects pattern?

  - by Marcus Munzert

  I am searching for a tool/framework that follows the naked objects pattern and is written in Java. I know about tools like for instance JMatter, Naked Objects and Domain Object Explorer. That's not exactly what I am searching for, though. Open source would be great, but doesn't need to be. My intention is to use that tool/framework for the purpose of model-driven software development to do the modeling part. Ideally, such a tool/framework would provide the option to use JPA to store/load objects.

• What should I do to recompile my static library (originally written in VS6) in visual studio 2008?

  - by user370387

  There is a static library A with c++ classes wrapped by a C API in VS6. I developed a static library B in VS6 using callbacks from library A. The library B is used by the program C (commercial software) as a "user defined library" and linked to produce the program D. Questions: 1) When program C uses VS 6 it works, should it work fine with VS 2008? Because it doesn't. 2) When I tried to recompile library B in VS 2008 it gave me a .lib file with only 28KB, and the old one had more than 2MB. Is it ok? What Am I probably doing wrong? Thanks in advance

• Continuous integration with multiple branch development

  - by ryanprayogo

  In the project that I'm working on, we are using SVN with 'Stable Trunk' strategy. What that means is that for each bug that is found, QA opens a bug ticket and assigns it to a developer. Then, a developer fixes that bug and checks it in a branch (off trunk, let's call this the bug branch) and that branch will only contain fixes for that particular bug ticket When we decided to do a release, for each bug fixes that we want to release to the customer, a developer will merge all the fixes from several bug branch to trunk and proceed with the normal QA cycle. The problem is that we use trunk as the codebase for our CI job (Hudson, specifically), and therefore, for all commits to the bug branch, it will miss the daily build until it gets merged to trunk when we decided to release the new version of the software. Obviously, that defeats the purpose of having CI. What is the proper way to fix this issue?

• How have your coding values changed since graduating?

  - by Matt

  We all walked out of school with the stars in our eyes and little experience in "real-world" programming. How have your opinions on programming as a craft changed since you've gained more experience away from academia? I've become more and more about design a la McConnell : wide use of encapsulation, quality code that gives you warm fuzzy feelings when you read it, maintainability over execution performance, etc..., whereas many of my co-workers have followed a different path of fewer middlemen layers getting in the way, code that is right out in the open and easier to locate, even if harder to read, and performance-centric designs. What have you learned about the craft of software design which has changed the way you approach coding since leaving the academic world?

• "Winamp style" spectrum analyzer

  - by cvb

  I have a program that plots the spectrum analysis (Amp/Freq) of a signal, which is preety much the DFT converted to polar. However, this is not exactly the sort of graph that, say, winamp (right at the top-left corner), or effectively any other audio software plots. I am not really sure what is this sort of graph called (if it has a distinct name at all), so I am not sure what to look for. I am preety positive about the frequency axis being base two exponential, the amplitude axis puzzles me though. Any pointers?

• What is the benefits and drawbacks of using header files?

  - by vodkhang

  I had some experience on programming languages like Java, C#, Scala as well as some lower level programming language like C, C++, Objective - C. My observation is that low level languages separate out header files and implementation files while other higher level programming language never separate it out. They use some identifiers like public, private, protected to do the jobs of header files. I saw one benefit of using header file (in some book like Code Complete), they talk about that using header files, people can never look at our implementation file and it helps with encapsulation. A drawback is that it creates too many files for me. Sometimes, it looks like verbose. It is just my thought and I don't know if there are any other benefits and drawbacks that people ever see and work with header file This question may not relate directly to programming but I think that if I can understand better about programming to interface, design software.

• Can't find Peopleware anywhere?

  - by ooo

  Many folks say that Peopleware is one of the best books for software professionals and managers, as I see a lot of people recommending it in the "have to read list." The strange thing is that I can't find a bookstore anywhere that actually has it. I found it on Amazon, but Borders, Barnes & Nobles, etc. don't have it and keep telling me it's out of print. Can anyone shed some light on whats going on here? Amazon doesn't stock it, it says its available from a few 3rd party sellers, but I tried two of them and both of them eventually refunded me and cancelled the order after stalling for a month.

• Can't edit IORegistryEntry

  - by yangumi

  Hi, I am creating a software on Mac and I would like to change the value of an IORegistryEntry. I can view it on the IORegistryExplorer, but I can't edit it. So it's my understanding that I have to edit it via code. Here is my code: CFMutableDictionaryRef matchingDict = IOServiceNameMatching("AppleUSBMultitouchDriver"); io_service_t service = IOServiceGetMatchingService(kIOMasterPortDefault, matchingDict); if(service) { CFStringRef manufacturer = IORegistryEntryCreateCFProperty(service, CFSTR("Manufacturer"), kCFAllocatorDefault,0); NSLog(@"%@", (NSString*)manufacturer); kern_return_t err = IORegistryEntrySetCFProperty(service, CFSTR("Manufacturer"), CFSTR("test")); NSLog(@"error = %d", err); } This will output 2010-04-10 16:09:09.015 Test[41548:a0f] Apple Inc. 2010-04-10 16:09:09.015 Test[41548:a0f] error = 0 But after I check the value in the IORegistryExplorer, it still doesn't change. Does anybody have any suggestions? Thank you

• What are the exact versions of stuff you have to install in order to be able to step-debug a Scala p

  - by Alex R

  How do YOU debug a Scala program? I mean YOU as in the person posting the Answer :) Please answer only from personal experience, not from stuff you've heard or read on the Internet. You should not believe everything you read on the Internet, especially tales of complex open-source software configurations that actually work :-) The are many Java tools which claim to support Scala in some way or another, but I have so far struck out in trying to get any one of them to actually let me set a breakpoint in Scala code and step through it. These are big, major open-source IDEs I'm talking about here. The main problem in getting a debugger to work seems to be the "version hell" with fast-changing IDEs, Plug-Ins, JDKs, and the Scala language itself. Hence, the more detailed re-statement of the question is appropriate: What is the exact version number of the IDE, Plug-In, JDK, Scala, and even Operating System, that you are successfully using? My question is related to this one, but wider in scope: http://stackoverflow.com/questions/2272705/how-to-debug-scala-code-when-outside-of-an-ide Thanks

• What's the best way to implement one-dimensional collision detection?

  - by cyclotis04

  I'm writing a piece of simulation software, and need an efficient way to test for collisions along a line. The simulation is of a train crossing several switches on a track. When a wheel comes within N inches of the switch, the switch turns on, then turns off when the wheel leaves. Since all wheels are the same size, and all switches are the same size, I can represent them as a single coordinate X along the track. Switch distances and wheel distances don't change in relation to each other, once set. This is a fairly trivial problem when done through brute force by placing the X coordinates in lists, and traversing them, but I need a way to do so efficiently, because it needs to be extremely accurate, even when the train is moving at high speeds. There's a ton of tutorials on 2D collision detection, but I'm not sure the best way to go about this unique 1D scenario.

• Floating point Endianness?

  - by cake

  Hi I'm writing a client and a server for a realtime offshore simulator, and, as I have to send a lot of data through a socket, I'm using binary data to maximize the ammount of data I can send. I already know about integers endianness, and how to use htonl and ntohl to circumvent endianness issues, but my application, as almost all simulation software, deals with a lot of floats. My question is: Is there some issue of endianness whean dealing with binary formats of floating point numbers? I know that all the machines where my code will run use IEEE implementation of floating points, but is there some endianness issue when dealing with floats? Since I only have access to machines with the same endian, I cannot test this by myself. So, I'll be glad if someone can help me with this. Thanks in advance.

• Windows XP Rejecting Digital Signature

  - by ajs410

  I don't want to see unsigned driver warnings while installing a driver, so I'm trying to digitally sign a driver using signtool, inf2cat, and a Software Publishing Certificate. Vista x64 requires the drivers to be digitally signed or it flat out rejects them, but I have managed to get Vista x64 to accept the driver, so I know I'm doing the process correctly. However, I repeat the process for the Windows XP x86 driver. inf2cat and signtool both return successful results, signtool verifies the digital signatures, right-click - properties on the file verifies the digital signature too. However, when I go to load the driver in Windows XP, it still prompts me with an unsigned driver warning. Why does XP consider the file unsigned, but Vista does not?

• asp.net mvc cookies not persisting on local server (aspnetserve)

  - by DW

  Hi. Trying to run an MVC app on the 'portable' web server. Software is aspnetserve. (http://www.ohloh.net/p/aspNETserve) Cookies do not persist. They do fine when I run from visual studio debug. Code is fine, seemingly. Only are dead (fail to persist from page to page) when I use this server. My solution requires deploying a portable local solution like this for the app. (this isn't just being done for purposes of testing) Rather stumped right now. Any bright ideas? Thank you.

• "Introduction to Computer Science and Programming" for a beginner.

  - by Richard

  Hi everyone! Im new here and also new to developing software and programming, and with new I mean 0 experience or schooling for it. As Im currently studying medicine via internet and I use a computer on an average of about 8-9 hours a day, this has lead me to get very interested in programming. I got a link from a fellow Redditor and I got some questions before I dive into this project. http://ocw.mit.edu/OcwWeb/Electrical-Engineering-and-Computer-Science/6-00Fall-2008/CourseHome/index.htm Is this too much/hard for a beginner? Is Python™ programming language the way to go or would I be better off learning some other kind of language to begin with? What other ways of learning basic programming by myself is there? Are there any better ways for a complete beginner to start off? Thank you for your time!

• Converting a 16 bit tiff file to something viewable online?

  - by msandbot

  I need to take a 16 bit .tiff file and make it viewable on my website. To even view .tiff files many browsers require plugins. I found a software that could convert them to .jpg files but I was wondering if there is a way to do this independently. I am making my website using Ruby on Rails. I must be able to do the conversion from the website because the whole point of the website is to upload large folders of .tiff files and display them in an online slideshow. Any help would be appreciated. Thanks!

• Collaborative kernel development

  - by Raffo

  Hi, I have to develop a patch for the linux kernel (2.6) for an university course I'm attending. I have to develop this patch with a friend of mine and we need to edit the same files on our computers (2-3 PCs). So, we want to use something like a collaborative editor and/or a version control system. The problem is that we never used something like that and that we cannot release our software as open source till we take the exam. Obviously, we're using linux. I'm here to ask you suggestions in order to manage our work in the best way. Thank you

• SimpleDB direct client access

  - by AlexJReid

  One of the useful things about S3 for content storage is that a client can directly make a direct HTTP request to download the object. For instance, this is how Twitter serve up avatar images. SimpleDB provides an HTTP interface to data. Rather than having to write a proxy that sits inbetween SimpleDB and the client, is it possible for client software (i.e. desktop, mobile) to make calls to read values from a SimpleDB domain, without sharing credentials that shouldn't be shared? Or is a proxy in-between the only way to go?

• How to quantify your "slow" development machine?

  - by lance

  ( Please provide the question this one duplicates. I'm disappointed I couldn't find it. ) My development machine is "slow". I wait on it "a lot". I've been asked by decision makers who want to help to fairly and accurately measure that time. How do you quantify the amount of time you spend waiting on the computer (during compiles, waiting for apps to open every day, etc). Is there software which effectively reports on this sort of thing? Is there an OS metric (I/O something something, pagefile swapping frequency, etc, etc) that captures and communicates this particularly well? Some sort of benchmark you'd recommend me testing against?

• C# Count registry keys existing using a partial value

  - by cheeseman

  Microsoft.Win32.RegistryKey registryPath = Microsoft.Win32.Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Wow6432Node\Testing"); Microsoft.Win32.RegistryKey entryKey = registryPath.OpenSubKey("Entry Point"); I have a lot of keys in Testing, in the format: "Entry Point 011", "Entry Point 123" - so Entry Point with random numbers after it. Would I be able to search the registryPath variable above and get a count of the number of keys containing the "Entry Point" keyword? Assuming that there are also other keys existing without this keyword. At the moment I have been using a for loop and looping for all possible combinations to get a count of all the keys, checking if the key exists or not, but as there are keys as high as "Entry Point 9000" having a for loop execute 9000 times is very inefficient. for (int i = 0; i <= highestEntryPointValue; i++) { Microsoft.Win32.RegistryKey entryKey = steamApps64.OpenSubKey("Entry Point " + Convert.ToString(i)); if (entryKey != null) { count++; } }

• Does anyone have an updated version of the SQLite .NET assembly, ie. SQLite 3.6.23.1 + possibly .NET

  - by Lasse V. Karlsen

  I'm at my wits end with the best .NET assembly version of SQLite, the one found at http://sqlite.phxsoftware.com. The only maintainer doesn't seem to have the time to update the library and it generally takes months, if not more, for newer versions to surface. Luckily, he has published the source code, so I'm hoping that someone else has made his/her own copy of it, and made the changes, and would be willing to share a copy. I've seen comments on the forums for the library to this effect, but sadly even the forum software seems to be grinding to a halt these days as password reminder emails seems to be lost to the big void, so I can't ask the few there that has said they have done it. So I'm here, hopefully the big userbase of StackOverflow can help. What I'm looking for: Updated with the latest changes to SQLite, ie. SQLite version 3.6.23.1 Possibly built for .NET 4.0 (I can do that if I can get a copy of working source) Does anyone have, or know of anyone, that has done this?

• Need some advice on a language to use for a 'presentation display board'

  - by joe90

  As part of the project i am working on I am looking to produce some software that works on a LCD display (think call center info boards) and displays various graphs (the bars grow etc in realtime, so incoming call stats etc etc) and flicks between various 'plug-ins'. The problem is deciding what language to use.. I am thinking about using the XNA framework, as this will allow me to do some nice 3d effects, add a nice glow effect, play videos etc. I can have for example the company logo defused spinning slowly behind the current data display. I know however, the XNA framework is a bit left field for this. Or is there a better alternative? Thanks..

• Does anybody have practice in programming PCMEF - architectures?

  - by Erkki

  PCMEF is an architecture style presented in the book Practical Software Engineering by Maciaszek and Liong. The layers are: P: Presentation C: Controller M: Mediator E: Entity F: Foundation. It is some kind of enchancement compared with MVC - architecture. I recommend it to interactice, data and communicating - oriented purposes. I have programmed it using Visual Prolog. Foundation in my applications is the data model (domains) for the application. PCMEF is like a simulated computer: Presentation is the display, Controller the user interface and event handling, Mediator the internal logic and data highway. Entity is the database or external interfaces and F defines the knowledge. This is a really nice small architecture. Does any other have experiance of it?

• Microphone input

  - by George

  I'm trying to build a gadget that detects pistol shots using Android. It's a part of a training aid for pistol shooters that tells how the shots are distributed in time and I use a HTC Tattoo for testing. I use the MediaRecorder and its getMaxAmplitude method to get the highest amplitude during the last 1/100 s but it does not work as expected; speech gives me values from getMaxAmplitude in the range from 0 to about 25000 while the pistol shots (or shouting!) only reaches about 15000. With a sampling frequency of 8kHz there should be some samples with considerably high level. Anyone who knows how these things work? Are there filters that are applied before registering the max amplitude. If so, is it hardware or software? Thanks, /George

• 600 tables in DDBB

  - by Michael

  Hi all, I'm a very young software architect. Now I'm working in a very large and I have to lead a group of developers to rewrite all the mortgage system of the bank. I'm looking at database tables and I realize that there is no any data model, neither documentation. The worst part is that there are about 1000 tables in dev environment, and like 600 in production. I trust more the production environment, but anyway, what can I do? I mean, I can suicide me or something, but is there any good reverse engineering tool, so at least I could get the schema definition with the relations between tables and comments extracted from the fields? Can you advice me something? Thanks in advance.
