• CI Build status output alternatives

  - by Brett Rigby

  We currently use Cradiator to display the status of our continuous integration (CI) builds from CruseControl.net, on a 42" Samsung television on display high-up in our IT department. Cradiator is a great starting place, but we're getting to the point whereby we're having lots of projects on there and it's starting to get a bit 'full'. What I'd like to know is, what do you use to display your build statuses? Custom software? Off the shelf stuff? etc. Alternatively, I'm looking for ideas on how we improve on Cradiator.

• 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?

• Handover document for complete systems

  - by viraptor

  Hi, I need to create a handover document for a fairly large system consisting of all the stuff you'd expect from a telecom deployment: many servers, database clusters which copy some data between them in specific ways, tons of log files, both off-the-shelf and locally developed software, scripts, network configurations, local know-how, etc. It's really got as many sysadmin-typical elements, as development ones. The target of this document are in the first place sysadmins who take over the day-to-day operation tasks and some problem resolving, and in the second place people who want to learn about the system in general. Is there some place I can learn about how to write something like that? It could just as easily be a 10 page "what's where", as a 500 pages book about "all things telephony". Maybe it should be more than one document really. Please link some useful resources / books I could use for this task. PS: this is intended to be internal only, customer interactions etc. are out of scope here

• Transferring data to (Windows) Mobile Devices

  - by Ritu

  I created an app for Windows Mobile 6.5 and am fairly happy with it. However, if anyone else need to use this app, they will have to transfer an initial file (txt or csv) to the device. For a developer this isn't a problem but is this too much to ask of an end user? Granted, they will want to move (sync) data back to their desktop after the device's data have been updated. So how do other apps solve this problem? Do I need to provide some kind of syncing software?

• Can Connect to 3G Modem via GSMComm but cannot see any SMS

  - by user305044

  Hi, I'm trying to write an application that receives SMS messages into the app I'm developing (in C# if you care :). Research indicates the best bet is to use GSMComm library. I've downloaded the library and using the demo app I have managed to connect to the 3g modem (a Huawei E1756) but when I query it for SMS's received it comes back with 0. Interestingly if I use the software that comes with the application then I can see the messages. Anyone got any clues on why this would be? Or other tips on how to retrieve the messages? Cheers, Kym

• API For Flex Apps To Interact

  - by dimo414

  I have a large flex application (the app) running on one server, and many small flex applications (widgets) running on another server, which are to be included in the app so that visually the user see's one continuous application. Due to proprietary third party software, this structure cannot be changed. I am looking for some way to allow the app and the widgets to communicate, allowing the app to make changes to the widgets and the the widgets to notify the app when events are triggered, so that user interaction is fluid and continuous. There are a few related questions which indicate it's possible to do this by setting up event triggers and listeners. I am wondering if there is any standardized way to do this (the answers aren't very clear) or if anyone has developed a library or API to make this easier.

• What are the flavor-of-the-month technologies that have now become obscure?

  - by Andreas Grech

  For this question, I am looking for programming languages, technologies and standards that where considered as a flavour-of-the-month in their prominent time but have since been forgotten in today's programming world. Also, with what have they been replaced? I am relatively new to the software development industry compared to most of the people here (with just only 5 years of experience), and from this question I am looking to learn about some of the now-obscure technologies that have been around during your time. Just for clarification, what I mean by flavour-of-the-month is technologies that had been extensively in their time but today have become obscure and forgotten; maybe replaced by other better ones

• Dynamically setting WCF endpoint

  - by Matt

  Ive just started using WCF with silverlight and its working fine. But one thing that is bugging me is the address of the .svc. Why is it statically set in the .config? Would it be possible to set it when creating an instance of the proxy class? And if so, is there a way to set it to the current address? Our software will be deployed on many different domain and we cant change the config every time. The svc will always be in the same domain as the silverlight page. Thanks.

• Xcode 3.1.2 locks up when loading C++ project...?

  - by Stabledog

  I have a project which builds correctly from the command line. On one of my Macs (10.5) running Xcode 3.1.2, I can load it and build it in the Xcode IDE. On my other Mac (same configuration of software), Xcode sometimes loads the project, but always locks up with a spinning beach ball at some point before the build is done. Sometimes this occurs as the project is loaded, sometimes late in the build. I've tried doing a 'clean' on the project, I've tried pulling in the source code fresh from source control. So far, no luck -- I have to kill Xcode and in effect, cannot develop on this particular Mac. I've uninstalled and reinstalled Xcode. Any clues?

• .NET Multipage Tiff with Lossy Compression

  - by Adam Berent

  I need a way to take several jpgs and convert them into a single multi page Tiff. I have that working using GDI+ however it only works with the compression LZW which is lossless. This means that my 3 50KB Jpgs turn into 3MB multipage Tiff file. This is not something I can accept for the software that I am working on. I know that Tiff Image format can use a JPG compression scheme but GDI+ does not seem to support this. If anyone knows how to do this in .NET (C#) or of any component that does this conversion.

• 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.

• What do you read?

  - by sixtyfootersdude

  I have almost finished reading all the articles on Joel on software. I am a new developer and hoping to get something interesting to read. Here is what is currently on my list: Java Concurrency in Practice by Brian Goetz sed & awk by Dougherty & Robbins (O'Reilly) The Pragmatic Programmer by Andrew Hunt and David Thomas Head First Design Patterns Can anyone suggest anything else? Would especially like something similar to Joel. Something that is a bit edgy but informative. Pragmatic programmer has some key concepts but is a bit dry.

• ASP.NET 3.5 Stateless Session Managment and connection pooling?

  - by Norm

  I am designing an ASP.NET (3.5) web application that connects to a Rocket Software UniVerse database. I am in the planning stages right now and need some help in being pointed in the right direction. I am brand new to ASP and C#. I am shooting for a RESTful design and a MVC pattern. Rocket provides a .NET library called UniObjects.NET which handles everything for connecting and retrieving information from the database. What would be the best way to in general to log my users into the database, then use that session via connection pooling? I see that in 3.5 there is the ASP.NET Routing Infrastructure and that looks promising am I in the right direction on this? Also does C# support decorators like Python and Java?

• How to retain one million simultaneous TCP connections?

  - by cow

  I am to design a server that needs to serve millions of clients that are simultaneously connected with the server via TCP. The data traffic between the server and the clients will be sparse, so bandwidth issues can be ignored. One important requirement is that whenever the server needs to send data to any client it should use the existing TCP connection instead of opening a new connection toward the client (because the client may be behind a firewall). Does anybody know how to do this, and what hardware/software is needed (at the least cost)? Thanks in advance for any suggestions.

• Non-Profit Volunteer Opportunities

  - by Sean

  I have seen questions on SO regarding volunteering for potential employers or volunteering to help out on open source projects. But what about putting your IT skills to use at traditional non-profit organizations as a volunteer? I would like to volunteer some time to a worthwhile cause in 2010, but am having a hard time finding organizations who may need IT help. Does anyone do this? Are there any websites out there to help one find organizations looking for such help? I would think some must have a need for free software development type work? I saw a bit on 'WeVolunteer' that publishes a database of volunteer opportunities (http://www.wetv.com/volunteer.html), but it seems to be more 'typical' volunteer opportunities (soup kitchens, walk-a-thons, etc).

• Global variable not stable after platform changed.

  - by user350555

  Our embedded system is built on a hw/sw platform made by enea. After the platform updated recently, we found some operations on the global variable keep crashing the system. For example, we have a global map structure holding some data. We can insert/iterate the map once or twice, then the address of the elements in the map suddenly changed to some forbidden addresses like 0x0 or 0x1d, the system just crash. The only different before/after the platform update is : 1) sw part: It's a c++ software and We changed the compiler from diab cc to gcc. 2) hw part: we have a new board, but the cpu is still powerpc405s. I tried every possible way but still can't figure out the reason. Any thoughts?

• Does normalization really hurt performance in high traffic sites?

  - by Luke101

  I am designing a database and I would like to normalize the database. I one query I will joining about 30-40 tables. Will this hurt the website performance if it ever becomes extremely popular? This will be the main query and it will be getting called 50% of the time. The other queries I will be joining about 2 tables. I have a choice right now to normalize or not to normalize but if the normalization becomes a problem in the future i may have to rewrite 40% of the software and it may take me a long time. Does normalization really hurt in this case? Should I denormalize now while I have the time?

• MC75 using symbol.imaging.device libraries for program

  - by Christy

  UPDATE: I found another library in the Windows Mobile - CameraCaptureDialog - this did the job - never did figure out the zero length available devices... Hi all, I have a .net application running on a symbol mc75 (motorola) using the scanner. I am now trying to add functionality for the camera and I am running into issues. To find the 'devices' you are supposed to use the library's 'available devices' function. With the barcode it is symbol.barcode.devices.availabledevices and it returns two items (you can scan from the scanner or using the camera device) However, when I do the camera library it does not find any devices - symbol.imaging.devices.availabledevices returns 0 I can take a picture using the software on the mc75, so I know the functionality is there, I just can't figure out how to get to it programmatically.... Does anyone have any ideas? Thanks for any help!

• How to extract a single function from a source file

  - by Adam Matan

  Hi, I'm working on a small academic research about extremely long and complicated functions in the Linux kernel. I'm trying to figure out if there is a good reason to write 600 or 800 lines-long functions. For that purpose, I would like to find a tool that can extract a function from a .c file, so I can run some automated tests on the function. For example, If I have the function cifs_parse_mount_options() within the file connect.c, I'm seeking a solution that would roughly work like: extract /fs/cifs/connect.c cifs_parse_mount_options and return the 523 lines of code(!) of the function, from the opening braces to the closing braces. Of course, any way of manipulating existing software packages like gcc to do that, would be most helpful too. Thanks, Udi EDIT : The answers to Regex to pull out C function prototype declarations? convinced me that matching function declaration by regex is far from trivial.

• copying files from one windows server to another

  - by Saju Pillai

  I have to copy a file from a windows 2008 server to one or more windows 2008 servers. I have accounts on the target machines with enough privileges to let me use powershell remoting and use wmi. The remote machines do not run ftp, ssh or similar file transfer mechanisms. I am not allowed to install software or run new services on the target server. I can run services on the source server. The file copy action must be initiated from the source server. i.e. I cannot manually logon to the target machines and initiate the copy - though an automated way to do this is acceptable. Is it possible to use WMI or PowerShell Remoting to push or pull the file from the source to the target ? Is it possible to invoke some sort of built in http client or invoke the BITS service/agent on the remote servers to pull files from the source server ? Other suggestions please.

• Reporting. MS Word templates population required

  - by Andrew Florko

  Application we developed fills MS Word templates with data from Database. Customers require to have ability edit Word templates via MS Word (change style, font, layout e.t.c) with no additional software to be installed and no training. AFAIK, Sql Reporting Services and Crystal Reports can't populate MS Word templates produced in MS Word. So we implemented our custom solution that maps .net classes onto xml-saved MS Word documents. It looks like we declare class MyTemplate { // maps to [age] field declared in ms document straight in the text int Age { get; set; } // maps to table by attributes applied to property (omitted) List<Person> Persons { get; set; } } We also implemented images insertion. Are there any free libraries for this task or may be you use your own MS-word templators in your projects?

• How to avoid becoming a programmer while still beign closely involved with computer science/Industry

  - by WeShallOvercome

  I am studying computer science (A masters at an Ivy league), however most of the jobs i find involve way too much of programming. And frankly programming is not an issue, however programming without a meaning (read financial institution (non trading), other non mainstream jobs) bore me to death! I dont want to end up becoming a .NET,C#, Java kind of programmer. Can someone tell where i should look for jobs if i wish to do some real computer science work such as Machine Learning etc. I don't mind programming but becoming a Financial Software dev at Bloomeberg or an SDET at Microsoft isn't actually one of my goals. [note: I have interviewed for intern both positions listed above, and thankfully i got an intern for a data mining position in a top 750 Alexa rank web company] Sorry if angered anyone with a subjective question

• How can I make an Access database readable from the web while it is open in MS Access?

  - by djdilicious

  I have a website using ASP with an MS Access DB back-end for storing mainly blog posts. My company has a very long software approval process so I am stuck with what I have (i.e. I must use Access). I use server-side javascript to retrieve posts stored in the database using OLEDB calls. Everything works fine except that I cannot read any tables from the database when it is open in the MS Access program. The page displays an error message about the file being in use. This could lead to significant downtime while I am doing any work within Access. How can I make the file readable by my ASP application while it is open in Access?

• Commercial CMS on Google App Engine, violation of terms?

  - by Yaggo

  I'm developing commercial CMS running on Google App Engine. I'm thinking of selling it in two ways: 1) Software as a service (SaS). The CMS running in my App Engine account (as single app), hosting the sites of all customers. A turn-key solution for "end user" customers. 2) Licence for running the CMS in customer's own App Engine account. Targeted for digital agencies for reselling as SaS. Being not a lawyer myself, I don't trust my abilities to read between the lines of TOS jargon. Counting on the general knowledge of SO community, my question is: do the above scenarios violate the App Engine Terms of Service?
