• installing ruby/gnome2 on ruby1.9

  - by sawa

  My purpose is to install ruby/gnome2 and make it work with ruby1.9 on Ubuntu9.10. I already have ruby/gnome2 working with ruby1.8, but I need to make it work with ruby1.9. I also have ruby1.9 working. When I run within ruby-gnome2-all-0.19.3: ruby1.9 extconf.rb it eventually gives me: Target libraries: glib, gdkpixbuf, pango, atk, gtk, gconf, libglade Ignored libraries: gnomeprintui, panel-applet, gtksourceview, gtksourceview2, bonoboui, bonobo, libart, goocanvas, rsvg, gnomeprint, gstreamer, vte, gnomevfs, poppler, gnomecanvas, gtkglext, gnome, gtkmozembed, gtkhtml2 so it seems some packages failed to be installed. When I look for the log for example for the gnomeprintui part, it exits after returning: cheking for libgnomeprinrui-2.2... no but apt-get says I have the newest version of it. Can anyone tell me how to resolve this problem?

• is there any light weight javascript date picker

  - by Zain Shaikh

  I am using JQuery Date picker, but it is too much heavy, the minified version of ui.datepicker.min.js is of 44 KB. the images of datepicker have their own weigh. the jquery framework is of 59 KB. and total images on page are of around 80 KB the total html of page is around 70 KB and the css file size is around 72 KB. and much more, and all the things go upto 600 KB. which is 0.6 MB. do you think user will wait for 600 KB to be downloaded in the browser? it may take upto 8 - 10 secs. and I dont think that user will wait for such long time. I want to keep my website light weight. is there any light weight javascript date picker.

• Entity Framework - Using a list as a paramater in a compiled query

  - by vdh_ant

  Hi guys Just wondering if anyone knows whether I should be able to pass in list into a compiled query and have the query perform a contains operation? The reason why I ask is that I have a scenario where I need to do this, yet at run time I am getting the following error... The specified parameter 'categories' of type 'System.Collections.Generic.List`1[[System.Int32, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]]' is not valid. Only scalar parameters (such as Int32, Decimal, and Guid) are supported. I can understand why this might be the case but I was wondering if anyone knows a way around it. Cheers Anthony

• Problem with constants in application.ini after PHP upgrade

  - by Marek

  Hi, I've upgraded PHP on my local dev system to version 5.3.0, and there is some problem when I use constants in application.ini - following manual http://framework.zend.com/manual/en/learning.quickstart.create-project.html I have: bootstrap.path = APPLICATION_PATH "/Bootstrap.php" which leads to: Warning: require_once(APPLICATION_PATH/Bootstrap.php) [function.require-once]: failed to open stream: No such file or directory in Zend\Application.php on line 320 any ideas? SOLVED: Actually name of my constant was _DIR_APPLICATION (code above was copied from ZF manual) - problem lies in this underscore at the begining - it seems that parse_ini_file() in PHP 5.3.0 doesn't replace constants named like this. Short test - you need two files: test.ini bootstrap.path = _DIR_APPLICATION "/Bootstrap.php" bootstrap.class = "Bootstrap" and test.php <?php define('_DIR_APPLICATION', 'test'); $data = parse_ini_file('test.ini'); print_r($data); try to run, then change constant name to 'DIR_APPLICATION' (in both files) and compare result ;)

• How do I get Nant to use the 4.0 compiler to target .Net 3.5

  - by Rory Becker

  Yes I know that sounds a little bit crazy, but I've got .Net 3.5 deployed in the field and I'd like to use the new 4.0 compiler to target it. There are several new syntactic sugar features in the latest versions of Vb.Net and C# which I would like to use,but I am unable (just yet) to enforce a new version of the .Net framework and CLR on my client base. Before the nay sayers jump in with both feet... I have just successfully used Studio 2010 to compile a 3.5 targeted app which used VB.Net auto properties (A new feature in VB.Net 10) so I know the compilers are capable somehow. So back to my question.... How do I convince Nant to use the 4.0 compiler, but to target .Net 3.5 (CLR 2.0) Update: I am using the csc and vbc tasks and not the Solution task. although I'd settle for an answer on how to do this direct with the compilers at this point.

• How to avoid clobbering files when creating a tar archive

  - by Andrew Grimm

  This question notes that it is possible to overwrite files when creating a tar archive, and I'm trying to see how to avoid that situation. Normally, I'd use file roller, but the version installed is playing up a bit (using 1.1 Gb of memory), and I'm not the system administrator. I looked at --confirmation and --interactive, but that only asks me if I want to add file x to the archive, not whether I want to overwrite an existing file. For example, tar --interactive -czvf innocent_text_file.txt foo* Will ask me about each file, but is perfectly happy to overwrite innocent_text_file.txt Is there any switch that acts like -i for cp? Note I am asking about creating an archive, not extracting an archive. Clarification What I'm worried about is accidentally doing something like this tar -czvf * #Don't do this! which would overwrite the first file listed in the glob. To avoid it, I want tar to complain if the first file mentioned already exists, like cp -i * #Don't do this! would check if it would cause you to overwrite an existing file.

• Looking for a reporting tool that will allow vector graphics in output file (PDF)

  - by Richard West

  I have been tasked with evaluating our current system that we use for creating and outputing reports. Currently we are using Crystal Reports ver 8, (I know that this is and old version.), which has a custom commandline app that we wrote in C# to execute the report for a given parameter passed through the command line. We like Crystal becuase it's easy to setup and design the report. It's also easy to print and create a PDF file from crystal using our custom commandline program. One of the problems/complaints that we have is that Crystal does does not appear to have a method that will allow us to create a PDF file with a vector images, such as our company logo. Crystal Reports always converts an image into a bitmap. When the PDF is printed, the results are less than flattering, and the PDF file size is increased. Does anyone have any recomendadtions for a reporting product that we should consider?

• Associating Worksheets with their Names using OpenXML SDK 1.0

  - by John Price

  I'm using version 1.0 of Microsoft's OpenXML SDK to do some basic parsing of .xlsx files. I can get and parse the worksheets, and I can get a list of worksheet names, but I cannot for the life of me figure out how to link up what name goes with what worksheet. I understand that an element like <sheet name="My Sheet" sheetId="1" r:id="rId1"/> in the workbook is linked up to a specific worksheet via the relationships defined in xl/_rels.xml, but I can't see where any of the relationship info is exposed in the API. I'm using C#, but any VB.NET examples would be just as helpful. I feel like this should be dead simple, but I can't figure it out. It also looks like it may be more straightforward in v2.0 of the SDK, but upgrading isn't an option at the moment.

• MS Access 2003 - Help understanding the structure of mdb, mde and be.....

  - by Justin

  Hi. I was just wanting some explanation as to what is going on once you have split your tables out into a back end file, and set an mde out for use. When a user accesses the mde, is the mdb still required to get to the tabes (or in order to make it work)? Let say I put these access apps on a shared drive for folks to use. If I split the be end on to the shared drive, and placed the mde on the shared drive, would I the mdb have to exist for that version mde to work (communicate with the tables)? Or does the mde sort of speak to the mdb which speaks to the tables? Hope this question makes sense. Thanks

• How can I make PowerShell run the original Start-Process cmdlet rather than the PSCX Start-Process c

  - by urig

  I have PowerShell v2.0 installed and on top of that, PSCX is installed. PSCX is the PowerShell Community Extensions (http://pscx.codeplex.com/Wikipage). It seems that I have two cmdlets called Start-Process installed and I'm guessing one is the original and the other is from PSCX. When I invoke Start-Process, the PSCX cmdlet is made to run. How can I make PowerShell run the original version instead? Helpful Evidence: When I run get-help start-process i get: Name Category Synopsis ---- -------- -------- Start-Process Cmdlet PSCX Cmdlet: Starts a new process. Start-Process Cmdlet Starts one or more processes on the local computer. When I run get-command start-process I get: CommandType Name Definition ----------- ---- ---------- Cmdlet Start-Process Start-Process [[-Path] <String>] [[-Arguments] <String>] [...

• Postgresql - one database for everyone, or one-database per customer

  - by user337876

  I'm working on a web-based business application where each customer will need to have their own data (think basecamphq.com type model) For scalability and ease-of-upgrades, I'd prefer to have a single database where each customer gets a filtered version of the data. The problem is how to guarantee that they stay sandboxed to their own data. Trying to enforce it in code seems like a disaster waiting to happen. I know Oracle has a way to append a where clause to every query based on a login id, but does Postgresql have anything similar? If not, is there a different design pattern I could use (like creating a view of each table for each customer that filters)? Worse case scenario, what is the performance/memory overhead of having 1000 100M databases vs having a single 1Tb database? I will need to provide backup/restore functionality on a per-customer basis which is dead-simple on a single database but quite a bit trickier if they are sharing the database with other customers.

• NULL handling with subselect in Hibernate Criteria API

  - by Jens Schauder

  I'm constructing a Hibernate Criterion, using a subselect as follows DetachedCriteria subselect = DetachedCriteria.forClass(NhmCode.class, "sub"); // the subselect selecting the maximum 'validFrom' subselect.add(Restrictions.le("validFrom", new Date())); // it should be in the past (null needs handling here) subselect.add(Property.forName("sub.lifeCycle").eqProperty("this.id")); // join to owning entity subselect.setProjection(Projections.max("validFrom")); // we are only interested in the maximum validFrom Conjunction resultCriterion = Restrictions.conjunction(); resultCriterion.add(Restrictions.ilike(property, value)); // I have other Restrictions as well resultCriterion.add(Property.forName("validFrom").eq(subselect)); // this fails when validFrom and the subselect return NULL return resultCriterion; It works ok so far, but the restriction on the last line before the return statement is false when validFrom and subselect result in NULL. What I need is a version which handles this case as true. Possibly by applying a NVL or coalesce or similar. How do I do this?

• What is the best way to set up a PHP development environment on a Mac?

  - by Edward Tanguay

  When I do PHP, I use XAMPP to set up a development environment on Windows, then upload to Linux servers, works very well. I'm now passing on a PHP project to a person who has a Mac so he needs a local PHP dev environment. I noticed XAMPP has a version for Mac which I will recommend. But knowing that Mac is always a bit different, has anyone used any other easy PHP environment setup tool for the Mac, or I could even imagine that Mac solves this issue more elegantly by e.g. having a web server ready to go upon first boot etc. What is the best way to set up a PHP development environment on a Mac?

• Web Application Project Deployment VS2010 - Precompile Views

  - by Malcolm Frexner

  Using Visual Studio 2010 Ultimate I created a ASP.NET MVC 2.0 Web Application. I read http://msdn.microsoft.com/query/dev10.query?appId=Dev10IDEF1&l=EN-US&k=k%28WEBAPPLICATIONPROJECTS.PACKAGEPUBLISHOVERVIEW%29;k%28TargetFrameworkMoniker-%22.NETFRAMEWORK%2cVERSION%3dV4.0%22%29&rd=true. Its about the new features for Web Application Deployment. I dont see an option to precompile Views. Also I dont see other options that where available in previous version of Web Deployment Project: ie if the web is compiled into a single assembly or into one assembly per page. I had the impression that Application Project Deployment is the scuccessor of Web Deployment Project.. maybe I am wrong about it. How should I precompile views now?

• Back again to use Rails 2.3.5 from Rails 3

  - by dreame4

  Hi, Recently, I had seen information about Rails 3.0 beta and I had wanted to trial it. So I used gem update and installed this version. But now, I need to go back to Rails 2.3.5. How could I do it? I was thinking about this two solutions: Uninstalling Rails 3. I read that somebody removed Rails 3 by using gem uninstall but he came across some problems then. Did anyone try to remove it in this way? Using different versions Rails at the same time. Is it possible at all? It will resolve all my problems but I could find nothing about this issue in google. Hope somebody could help me :) Greetings, dreame4

• Using MobileMe idisk as a git repository

  - by Ben Guest

  I am trying to use git and MobileMe as a version control system for a personal project I am working across several computers. So far i have done the following. Created and empty bare repository on my local computer $ mkdir myproject.git $ cd myproject.git $ git init --bare $ git update-server-info I then copied the myproject.git directory to the mobile me disk, and sync my computer with mobile me. I then switched to the directory where my project was on my local machine, set the remote origin and try to push the local repository to mobile me $ cd myproject $ git remote add origin https://<username>@idisk.me.com/<username>/myproject.git/ $ git push --all Im am then asked for my password twice. The first time is the mobile me password, any other password gets an error. After entering the second password, and believe me i've tried everything, terminal just hangs. So what am I doing wrong? (Besides trying to use mobileme as a git repository) Thanks, Ben.

• How to Use JQuery Click Event on Button in an AJAX Form

  - by dpierre23

  I admittedly don't know much about JQuery but I have an AJAX page where I need to trigger a click event when someone clicks a button, but because the button is not there on the initial page load, I'm having issues using the click event. In my code, I just want to run a function when a button is clicked. <script type="text/javascript"> //Run function when button is clicked $(document).ready(function() { $("#idOfButton").click(function() { doSomething(); }); }); //The function I want ran when page visitor clicks button function doSomething() { //Do Something } </script> Obviously this code doesn't work, but any suggestions on how to use .click? I'm only able to insert JS via a tag management system, so I can't hard code anything into the page. Also, the JQuery version is 1.4, so I can't use .on. Thanks for your help.

• how to automate upsizing from Access to SQL Server?

  - by Arne

  Hi, I need to automate the migration from an Access (2003) to an SQL Server DB (2005 or 2008). The upsizing should be done automatically as part of a build process. I need that because there are 2 versions of the software, a single user rich client and a web version. Access DB is used for single user to minimize setup effort, SQL Server to improve performance and scaling with many simultanious users. Access should be the "leading" DB, meaning devs do changes in Access DB and those are propagated to the SQL server within the build process. Many changes will occur, so doing it manually is not an option. I am new to the Microsoft world, so I dont know appropriate tools for that. What tools can I use and how? I know how to do it (by clicking) with the upsizing assistant. Perhaps I can automate that somehow? Thanks in advance for your answers. Cheers, Arne

• RegEx - Take all numeric characters following a text character

  - by Simon

  Given a string in the format: XXX999999v99 (where X is any alpha character and v is any numeric character and v is a literal v character) how can I get a regex to match the numeric characters following the v? So far I've got 'v\d\d' which includes the v but ideally I'd like just the numeric part. As an aside does anyone know of a tool in which you can specify a string to match and have the regex generated? Modifying an existing regex is one thing but I find starting from scratch painful! Edit: Re-reading this question I realise it reads like a homework assignment! However I can assure you it's not, the strings I'm trying to match represent product versions appended to product codes. The current code uses all sorts of substring expressions to retrieve the version part.

• Why doesn't the AdditionalLibPaths parameter work in MSBuild?

  - by AngryHacker

  I am trying to specify an additional folder to look for references when doing a command-line compile with MSBuild. The command line is as follows: msbuild C:\LUR.NET\LurReports.sln /t:Rebuild /p:AdditionalLibPaths=C:\Radio;TargetFrameworkVersion=v2.0 For whatever reasons, msbuild completely ignores the C:\Radio folder when looking for references. What am I missing here? P.S. I should mention that this box does not have Visual Studio installed. And the .sln is in version VS2008 and I am compiling it against .NET 2.0. P.S. I also tried placing double quotes around the path. Did not make a difference.

• Is it an MD5 digest in this Python script?

  - by brilliant

  Hello, I am trying to understand this simple hashlib code in Python that has been given to me the other day on "Stackoverflow": import hashlib m = hashlib.md5() m.update("Nobody inspects") m.update(" the spammish repetition here") m.digest() '\xbbd\x9c\x83\xdd\x1e\xa5\xc9\xd9\xde\xc9\xa1\x8d\xf0\xff\xe9' m.digest_size 16 m.block_size 64 print m I thought that "print m" would show me the MD5 digest of the phrase: "Nobody inspects the spammish repetition here", but as a result I got this line on my local host: <md5 HASH object @ 01806220> Strange, when I refreshed the page, I got another line: <md5 HASH object @ 018062E0> and every time when I refresh it, I get another value: md5 HASH object @ 017F8AE0 md5 HASH object @ 01806220 md5 HASH object @ 01806360 md5 HASH object @ 01806400 md5 HASH object @ 01806220 Why is it so? I guess, what I have in each line flowing "@" is not really a digest. Then, what is it? And how can I display MD5 digest here in this code? My python version is Python 2.5 and the framework I am currently using is webapp (I have downloaded it together with SDK from "Google App Engine")

• Ideas on collaborating with small number of people

  - by Mark Szymanski

  Hi, I am collaborating with someone on a project and currently use Skype for collaboration. I like it because we can be on a call to say things that are hard to say by typing out. We can share our screens so we can help with code writing. And we can use the text chat to copy-paste code between each other. We also use Subversion for version control. I just wanted to know what other people used for collaborating with others so I could see whats out there to use. Thanks!
