• Problem with truncation of floating point values in DBSlayer.

  - by chrisdew

  When I run a query through DBslayer http://code.nytimes.com/projects/dbslayer the floating point results are truncated to a total of six digits (plus decimal point and negative sign when needed). { ... "lat":52.2228,"lng":-2.19906, ... } When I run the same query in MySQL, the results are as expected. | 52.22280884 | -2.19906425 | Firstly, am I correct in identifying DBSlayer as the cause of this effect? (Or the JSON library it uses, etc.) Secondly, is this floating point precision configurable within DBSlayer? Thanks, Chris. P.S. Ubuntu 9.10, x86_64 Path: .

• SQLite and PostgreSql longtext

  - by Nik

  Hello all, Does anyone know how to change a column in SQLite and PostgreSQL to LONGTEXT? I have done so in MySQL successfully with: "ALTER TABLE projects MODIFY description LONGTEXT;" But this clause doesn't seem to work on SQLite. I tried hard to find documentation on PostgreSQL, but that site's format really makes people puke. SQLite's website is better but the only command I find relevant, alter table, doesn't seem to support changing column data type at all. ( infact, it doesn't even allow changing column name!!!) Thanks all!

• Migrating from Maven to SBT

  - by Vasil Remeniuk

  Hi people, As you know, SBT is compatible with Maven in some way -- SBT recognizes simple Maven POMs and can use dependencies and repositories specified in them. However, SBT wiki says that, if inline dependency is specified in SBT project definition, POM will be ignored (so using both in this case is impossible): Maven and Ivy configurations (pom.xml and ivy.xml) are ignored when inline dependency declarations are present. Does anyone know, if any kind of converter from Maven POM to SBT project definition exists (translating POM's XML into project definition Scala code)? I'm considering writing such script (that will help to migrate my old Scala/Maven projects to SBT), but want to know first, if this functionality already exists. Thanks in advance.

• Force VSProps settings to override project settings

  - by Steve

  I have a vsprops file that defines the optimizations all of our projects should be built with for Visual Studio 2008. If I set the properties for the project to "inherit from parent of project defaults" it works, and fills them in the vcproj file. However, this doesn't protect me from a developer checking in a project file that changes the optimizations. In this case, the project settings are used over the vsprops settings. I need to make it so that vsprops always takes precedence over what is in the vcproj file. Is this possible? Other workarounds are also welcome.

• MIDlet + BlackBerry API = verification error?

  - by Kilnr

  Hi, Is there any way to write a MIDlet, but still use BlackBerry API classes and functions (including the APIs that require code signing)? In particular, I'm trying to use Kuix (http://www.kalmeo.org/projects/kuix). A pure MIDlet + Kuix (so without BlackBerry stuff) works perfectly after I converted the jar/jad to a cod file. As soon as I add BlackBerry API-stuff (CoverageInfo.COVERAGE_DIRECT in this case) I get a verification error when trying to run the cod file: Error starting $name: Module $name has verification error 2410 at offset 9a4f What can I do to solve this?

• Framework Similar to Pylons for Ruby

  - by Travis

  I've been using Python for most of my web projects lately, and have come to really love the Pylons MVC framework. I like the incredible transparency (lack of magic), the built-in components they selected (sqlalchemy, formencode, routes), and the ability to easily change things up (use a different ORM or templating engine). Moving forward, due to constraints at my company, I'm going to be trying out Ruby rather than Python. I'm wondering if people with experience in both have any recommendations for a Ruby framework that is comparable to Pylons. Python is to Django as Ruby is to Rails Python is to Pylons as Ruby is to ?

• Where do DQL statements live in an application that is using Zend Framework and Doctrine

  - by Dewayne

  In an application that is using Zend Framework 1.10 and Doctrine 1.2, where should the DQL statements live if our application is built such that it has a Service Layer and a Gateway(aka Doctrine_Table) layer. It seems that our possibilities include: 1) Placing the DQL statements in the Service layer which seems to be a bit too high in our application hierarchy to store DQL. 2) Placing the DQL statements within each model's Table/Gateway which seems a bit redundant because we also need to expose the DQL statements that do things such as getAllUsers() through the Service layer. Which of these is a preferable design? We intend to make use of the Service layer as much as possible so that other projects might consume various parts of our application.

• How do you share your git repository with other developers?

  - by semi

  I have a central git repository that everyone pushes to for testing and integration, but it only is pushed to when features are 'ready'. While in the middle of a big task, developers frequently have many commits that stay on their harddrives. Sometimes in the middle of these projects I'd like to either see what another developer is doing, or show him how I've done something. I'd like to be able to tell another developer to just "pull my working copy" The only way I can think of is having everyone run ssh on their development machines and adding accounts or ssh keys for everyone, but this is a huge privacy and permissions nightmare, and seems like a lot of work to maintain. Should we just be pushing to that central repository in these cases? Should we be pushing after every local commit?

• review on django book vs django tutorial

  - by momo

  going through both the django book and tutorial, am a bit confused to the differences in approach (aren't they both written by the same people?) can anyone who has experience in both give a short review on them? i have decent python skills (largely untested though), but no experience at all in web apps and am trying to decide which one to stick to. i briefly looked in to practical django projects but that was a bit too complicated for me, my background is primarily bash scripting, the python i know i learned from an instant hacking tutorial and diving into python.

• Add Reference to a WCF Service Executable

  - by Sphynx

  I have 3 projects in my solution. 1 - client, 2 - server, 3 - WCF service library. Server executable exposes the service provided in the library. I need to add a reference to it, rather than to the library directly. When I open "Add Service Reference" and click "Discover", it only lists the library data, and doesn't list the executable server option. How do I reference a WCF executable service, so the client code would be generated automatically? I use VS 2010. Thanks for your help.

• I do not write tests. Am I stupid?

  - by Josh Stodola

  I've done a little bit of reading on unit testing and TDD, and I've never seriously considered writing tests to such a precise extent. Granted, I am not working on any projects that are ridiculously huge. If all I build are small apps, am I stupid for not writing tests? Edit: To clarify, when I say "small apps", I mean apps that are not going to control a persons life and/or their belongings. I generally build things that are supposed to make peoples lives easier and to make them more efficient.

• Design - Where should objects be registered when using Windsor

  - by Fredrik Jansson

  I will have the following components in my application DataAccess DataAccess.Test Business Business.Test Application I was hoping to use Castle Windsor as IoC to glue the layers together but I am bit uncertain about the design of the gluing. My question is who should be responsible for registering the objects into Windsor? I have a couple of ideas; Each layer can register its own objects. To test the BL, the test bench could register mock classes for the DAL. Each layer can register the object of its dependencies, e.g. the business layer registers the components of the data access layer. To test the BL, the test bench would have to unload the "real" DAL object and register the mock objects. The application (or test app) registers all objects of the dependencies. Can someone help me with some ideas and pros/cons with the different paths? Links to example projects utilizing Castle Windsor in this way would be very helpful.

• Aptana Studio 2.0: How to checkout SVN Project to SFTP remote dir?

  - by Brian Lacy

  If you're familiar with the excellent Aptana Studio IDE, you know it's based on Eclipse. You also know it comes pre-packaged with SFTP capability. I need to work on a remote server, where I have Apache installed; SFTP is ideal for this. I've installed the Subclipse plugin, and I can access and checkout projects from the Repo. I can create a new project from SVN source, which will download all the source to my chosen workspace or a specified location. But I can't figure out a way to combine these features! I need to create a Project on a remote server via SFTP but I need to link the source to a repository. Is there any way to do this?

• There are lots of useful answers about estimating the cost of a project. Are there any recommendatio

  - by Chrys

  Let me clarify this a bit more. I started giving estimations about projects/tasks. I write everything down in a spreadsheet. I know that soon this spreadsheet won't help much (searching, recommending similar project estimations etc...) Do you have any recommendations for any tools I can use for keeping a track of all these estimations? Is there a tool out there that for example will give me related project estimations like stackoverflow gives me related questions when I type one question.

• When to use Spring Integration vs. Camel?

  - by ngeek

  As a seasoned Spring user I was assuming that Spring Integration would make the most sense in a recent project requiring some (JMS) messaging capabilities (more details). After some days working with Spring Integration it still feels like a lot of configuration overhead given the amount of channels you have to configure to bring some request-response (listening on different JMS queues) communications in place. Therefore I was looking for some background information how Camel is different from Spring Integration, but it seems like information out there are pretty spare, I found: http://java.dzone.com/articles/spring-integration-and-apache (Very neutral comparison between implementing a real-world integration scenario in Spring Integration vs. Camel, from December 2009) http://hillert.blogspot.com/2009/10/apache-camel-alternatives.html (Comparing Camel with other solutions, October 2009) http://raibledesigns.com/rd/entry/taking_apache_camel_for_a (Matt Raible, October 2008) Question is: what experiences did you make on using the one stack over the other? In which scenarios would you recommend Camel were Spring Integration lacks support? Where do you see pros and cons of each? Any advise from real-world projects are highly appreciated.

• How to learn as a lone developer?

  - by fearofawhackplanet

  I've been lucky to work in a small team with a couple of experienced and knowledgeable developers for the first year of my career. I've learned a huge amount. But I'm now getting transferred within my company, and will be working on solo projects. I'll cope, but I know I'll make mistakes and won't always produce the best solutions without someone to guide me and review my output. I'm wondering if anyone has any tips in this situation. How can I keep learning? What's the best way to monitor and asses the quality of my work? How can I ensure that my career and skills don't stagnate?

• C++: what regex library should I use?

  - by Stéphane

  I'm working on a commercial (not open source) C++ project that runs on a linux-based system. I need to do some regex within the C++ code. (I know: I now have 2 problems.) QUESTION: What libraries do people who regularly do regex from C/C++ recommend I look into? A quick search has brought the following to my attention: 1) Boost.Regex (I need to go read the Boost Software License, but this question is not about software licenses) 2) C (not C++) POSIX regex (#include <regex.h>, regcomp, regexec, etc.) 3) http://freshmeat.net/projects/cpp_regex/ (I know nothing about this one; seems to be GPL, therefore not usable on this project) Thanks.

• Our VPS is being used as a Warez mule

  - by Mikuso

  The company I work for runs a series of ecommerce stores on a VPS. It's a WAMP stack, 50gb storage. We use an archaic piece of ecommerce software which operates almost entirely client-side. When an order is taken, it writes it to disk and then we schedule a task to download the orders once every 10 minutes. A few days ago, we ran out of disk space, which caused orders to fail to be written. I quickly hopped on to delete some old logs from the mailserver and freed up a couple of GB pretty quickly, but I wondered how we could fill up 50gb will nothing much more than logs. Turns out, we didn't. Hidden deep within the c:\System Volume Information directory, we have a stack of pirated videos, which seem to have appeared (looking at the timestamps) over the past three weeks. Porn, American Sports, Australian cooking shows. A very odd collection. Doesn't look like an individual's personal tastes - more like the VPS is being used as a mule. We have a 5-attempts and you're blocked policy on our FTP server (plus, there is no FTP account with access to that directory), and the windows user account has had it's password changed recently. The main avenues are sealed - and logs can verify that. I thought I'd watch and see if it happened again, and yes, another cooking show has appeared this morning. I am the only one to know of this problem at my company, and only one of two with access to the VPS (the other being my boss, but no - it's not him). So how is this happening? Is there a vulnerability in some of the software on the VPS? Are the VPS owners peddling warez across our rented space? (can they do this?) I don't want to delete the warez in case it is seen as a hostile action against this outside force, and they choose to retaliate. What should I do? How do I troubleshoot this? Has this happened to anyone else before?

• importing a project into a svn repository question

  - by ajsie

  im using netbeans for svn. i open a project in netbeans and then i import it to a svn repo. it seems that although im only importing the project folder, svn creates .svn folders in all folders within this project folder. why is that? i thought that i was only creating .svn folders to checked out projects, not imported ones? now this folder acts very weird, when i open this folder as a project in netbeans, netbeans treats it like a svn folder some way. is this normal? cause i want this one to not be under SVN.

• How to implement SVN pre-commit hook with best performance?

  - by mliebelt

  We have the following tools in place: Subversion (Version 1.5.9) Polarion (version 3.2.2) Polarion is based on Subversion, so on every action that changes anything (which is often the case), Polarion will use a Subversion commit to change anything. All things are currently stored in one and only one repository, so every commit of every user (some 100-200 on the same repository) will trigger the pre-commit hook. So what is the best strategy to provide pre-commit hooks that will trigger only for some, but not all projects run as fast as possible, because every pre-commit hook will block all other commits. We have tried to implement pre-commit hooks with Java (using SVNKit), but this will start on every commit a Java VM. So any ideas how to implement that nicely?

• Is it possible to use WIndows Speech Recognition Engine in a word pronounciation game?

  - by XBasic3000

  I use to create an application that uses the windows speech recognition engine or the SAPI. its like a game for pronounciation that it give you score when you pronounce it correctly. but when i started experiments with SAPI, it has poor recognition unless if you load a grammar on it (XML) its give best recognition result. but the problem now is closest pronounciation from the input text will be recognize. for example: Database - dedebase - correct. even if you mispronounce it. it gives you correct answers. without using the xml grammar when you say database it give you "in the base/the base/data base/etc..." please post your answer,suggestion,clarication. votes for best answer. is it posible or not? by the way i use delphi compiler on the projects....

• Rsync over ssh: "ERROR: module is read only" suddenly appeared

  - by user978548

  I've used from some time rsync/ssh to backup my shared host contents to my personal Synology NAS (212j for that matter), and it worked quite well. For information, I use a password-less ssh connection. 3 days ago, I updated my NAS software and since (or at least I believe it's since that), the backup won't work anymore. I get the following error on the host: rsync: writefd_unbuffered failed to write 4 bytes to socket [sender]: Broken pipe (32) ERROR: module is read only ..which I do not understand. beside that nothing changed that I know of in both source and destination that can be related to rsync or ssh, I did check a few things and all seems to be alright: I can still connect through ssh from the host to my NAS with the good user, so ssh stuff like keys haven't changed. I also have the correct file permissions on the NAS (I checked, and also tried to create files, directories, .. with the user used by rsync through ssh). I read here and there that the error means that I have to ensure that my rsyncd.conf have the right read only = no in it, but as far as I know, I never used rsyncd as well as I never configured anything for it and until now it worked like a charm.. I use the following command to do the backup: rsync -ab --recursive \ --files-from="$FILES_FROM" \ --backup-dir=backup_$SUFFIX \ --delete \ --filter='protect backup_*' \ $WDIRECTORY/ \ remote_backup:$REMOTE_BACKUP/ So I'm stuck and really can't figure out what happened. Edit: As suggested in comments, I also tried passing commands to ssh (but not from inside a ssh session), that worked as expected, and also tried a single rsync command, which didnt worked, failing just like the complete backup command. (sharedHost):hostuser:~ > touch test.txt (sharedHost):hostuser:~ > rsync test.txt remote_backup:backups/test.txt ERROR: module is read only rsync error: syntax or usage error (code 1) at main.c(1034) [Receiver=3.0.8] rsync: connection unexpectedly closed (9 bytes received so far) [sender] rsync error: error in rsync protocol data stream (code 12) at io.c(601) [sender=3.0.7] and (sharedHost):hostuser:~ > ssh remote_backup 'touch /abs_path_to_backups/backups/test2.txt && echo "ProoF" > /abs_path_to_backups/backups/test2.txt' (sharedHost):hostuser:~ > ssh remote_backup 'cat /abs_path_to_backups/backups/test2.txt' ProoF

• Why doesn't Microsoft release a 'proper' AJAX grid for ASP.Net

  - by Maxim Gershkovich

  Why doesn't Microsoft release a 'proper' AJAX grid for ASP.Net either as part of Visual Studio or the AJAX control toolkit? Has there been any discussion that anyone is aware of regarding this issue? Also does anyone have any open source suggestions for 'proper' AJAX gridviews? So far I have found one.... http://dotnetslackers.com/projects/AjaxDataControls/Default.aspx PS: By proper I mean a grid that actually uses XML responses rather than the nasty html javascript based injection that is the current nastyness of the gridview (EVEN IN VS 2010).

• Modern, Non-trivial, Pygame Tutorials?

  - by Gregg Lind

  What are some 'good', non-trivial Pygame tutorials? I realize good is relative. As an example, a good one (to me) is the one that describes how to use pygame.camera. It's recent uses a modern PyGame (1.9) non-trivial, in that it shows how to use it the module for a real application. I'd like to find others. A lot of the ones on the Pygame site are from 1.3 era or earlier! Info on related projects, like Gloss is welcome as well. (If your answer is "read the source of some pygame games", please link to the source of particular ones and note what is good about them)
