• Wordpress podcasting with youtube video hosting

  - by Salim Fadhley

  I'm trying to build a site based on Wordpress for a client. Eventually it will be used to publish videos which could be hosted locally, but to reduce costs it would be nicer if we could host all our videos on somewhere like YouTube or Vimeo. I'm looking for a plugin or a way of hacking an existing plugin in order to achieve this. The idea is that when we list a new item on the site, users of iTunes / iPod and any other (more) standards compliant podcatcher should be able to view the video. Ideally I'd like to get away without writing a single line of code, but that may not be possible. The best solution for me is the one which requires the least amount of work!

• Converting SQL to LINQ to XML

  - by Morano88

  I'm writing the following code to convert SQL to LINQ and then to XML: SqlConnection thisConnection = new SqlConnection(@"Data Source=3BDALLAH-PC;Initial Catalog=XMLC;Integrated Security=True;Pooling=False;"); thisConnection.Open(); XElement eventsGive = new XElement("data", from c in ?????? select new XElement("event", new XAttribute("start", c.start), new XAttribute("end",c.eend), new XAttribute("title",c.title), new XAttribute("Color",c.Color), new XAttribute("link",c.link))); Console.WriteLine(eventsGive); The name of the table is "XMLC" and I want to refer to it. How can I do that? When I put its name directly VS gives an error. Also when I say thisConnection.XMLC it doesn't work.

• Sharing Jinja2 templates between Pylons and Django applications

  - by Joe Holloway

  I'm writing a couple of Jinja2 templates that basically implement some common grid layouts. I'd like to be able to share this 'library' of templates between a Pylons app and Django app. I've hit a minor stumbling block in that Django's template context is accessible from the "top-level" of the template, whereas Pylons wraps your context inside the thread local c (or tmpl_context) variable. Here are some analogous examples that demonstrate this. Django from django.shortcuts import render_to_response ctx = {} ctx['name'] = 'John' return render_to_response('hello.html', ctx) hello.html: Hello {{ name }} Pylons from pylons import tmpl_context as c from myapp.lib.base import render c.name = 'John' return render('hello.html') hello.html: Hello {{ c.name }} What I'm trying to do is make it so that hello.html is the same across both frameworks. One way I see to do it is by wrapping the Django render_to_response and do something like this: ctx['c'] = ctx But that just doesn't feel right. Anybody see other alternatives to this? Thanks

• Supporting more than one codebase in ANSI-C

  - by Ilker Murat Karakas

  I am working on a project, with an associated Ansi-C code base. (let me call this the 'main' codebase). I now am confronted with a typical problem (stated below), which I believe I would be able to solve much easily if I had an object-oriented language at hand. The problem is this: I will have to start more than one codebases; i.e. I will have to start supporting a parallel codebase (even maybe more in the future). The initial codebases for all the new (i.e. parallel) codebases will initially be identical as the old (i.e. 'main') codebase. As we are talking about the 'C' language, I have till now been thinking of adding '#ifdef' statements to code, and writing the branch-spacific code inside those 'ifdef' blocks. Hoping that I made the problem clear (enough!), I would like to hear thoughts on clever patterns that would help me handle this problem elegantly in Ansi C. Cheers

• Best way to handle input from a keyboard "wedge"

  - by Mykroft

  I'm writing a C# POS (point of sale) system that takes input from a keyboard wedge magcard reader. This means that any data it reads off of a mag stripe is entered as if it were typed on the keyboard very quickly. Currently I'm handling this by attaching to the KeyPress event and looking for a series of very fast key presses that contain the card swipe sentinel characters. Is there a better way to deal with this sort of input? Edit: The device does simply present the data as keystrokes and doesn't interface through some other driver. Also We use a wide range of these types of devices so ideally a method should work independent of the specific model of wedge being used. However if there is no other option I'll have to make do.

• Are there Python ORMs out there that support multiple independent databases concurrently in use?

  - by sdt

  I'm writing an application in Python where I wish to use sqlite as the backing store for documents edited by the app, with documents generally living in memory, but being saved to disk-based databases when the application saves. Ideally I'd like to use something like an ORM to make access to the data from my Python application code simple. Unfortunately it seems like the majority of Python ORMs, including SQLAlchemy, SQLObject, Django, and Storm, associate the database connection (or engine or whatever) with the classes representing table data, rather than instances of those classes. This restricts these ORMs to working with a single database connection across all instances. Since I'd like to support having multiple documents open simultaneously, this isn't going to work for me. Are there any ORMs out there that support this usage model in Python? Bazaar seems to support this, but it's quite out of date, and at first glance appears to have some other shortcomings. Thanks for any suggestions!

• Cucumber vs. built-in testing? [Rails]

  - by yuval

  I asked a question about different testing frameworks yesterday. This question can be found here. Now that I have a better understanding of the different frameworks, I have a very simple question: With a basic understanding, but very limited experience with writing tests with rails' built in testing framework (basic assertions), would it be okay for me to jump directly to testing with RSpec, Webrat, and Cucumber? Thank you! As a side note: yes, this is an opinion based question, but I feel that the input received to this question is valuable enough to the community to keep this question open. Thanks.

• Automatic exit from bash shell script on error

  - by radman

  Hi, I've been writing some shell script and I would find it useful if there was the ability to halt the execution of said shell script if any of the commands failed. See below for an example: #!/bin/bash cd some_dir ./configure --some-flags make make install So in this case if the script can't change to the indicated directory then it would certainly not want to do a ./configure afterward it fails. Now I'm well aware that I could have an if check for each command (which I think is a hopeless solution), but is there a global setting to make the script exit if one of the commands fails?

• Increasing speed of webservice - howto

  - by Koran

  Hi, Our client-server product has the protocol between them as XML over HTTP. Here, the client asks a GET/POST query to the web server and the server responds with XML. The server is written using django. The server has to be on the web because there are many clients across the world using this. The server code uses extensive memoization and also there is very less db queries - most queries dont have any db queries, some of them has max 1. The biggest problem is the speed. Every query takes close to 5 seconds for the reply. The data replied is also very less - in the range of 4-6 Kb. What are the mechanisms to improve speed of the web service? Is this the usual way of writing a client-server? Are there other technologies and are we missing out on it? Thank you K

• Can I to remove the labels from the bibliography and keeping it in the reference?

  - by Tae

  I'm writing the bibliography of my report with thebibliography environment because I don't need a BibTeX database (or I don't have the time for learn how to customize or write a style). Well, using the optional argument [label] I can specify as I want the cite references are show, for example: \bibitem[PNUD1996]{PNUD1996} PNUD. Desarrollo Humano en Chile 1996. Santiago: PNUD, 1996. So, if I write: in \cite{PNUD1996}. it produces: in [PNUD1996]. But the label also appear in the bibliography: [PNUD1996] PNUD. Desarrollo Humano en Chile 1996. Santiago: PNUD, 1996. Can I to remove the label from the bibliography and keeping it in the reference? I mean, to get: in [PNUD1996]. and PNUD. Desarrollo Humano en Chile 1996. Santiago: PNUD, 1996. Thanks, and sorry for my English :(

• Best data-structure to use for two ended sorted list

  - by fmark

  I need a collection data-structure that can do the following: Be sorted Allow me to quickly pop values off the front and back of the list Remain sorted after I insert a new value Allow a user-specified comparison function, as I will be storing tuples and want to sort on a particular value Thread-safety is not required Optionally allow efficient haskey() lookups (I'm happy to maintain a separate hash-table for this though) My thoughts at this stage are that I need a priority queue and a hash table, although I don't know if I can quickly pop values off both ends of a priority queue. I'm interested in performance for a moderate number of items (I would estimate less than 200,000). Another possibility is simply maintaining an OrderedDictionary and doing an insertion sort it every-time I add more data to it. Furthermore, are there any particular implementations in Python. I would really like to avoid writing this code myself.

• Is there a limit on the number of mutex objects that can be created in a Windows process?

  - by young-phillip

  I'm writing a c# application that can create a series of request messages. Each message could have a response, that needs to be waited on by a consumer. Where the number of outstanding request messages is constrained, I have used the windows EVENT to solve this problem. However, I know there is a limit on how many EVENT objects can be created in a single process, and in this instance, its possible I might exceed that limit. Does anyone know if there is a similar limit on creation of mutex objects or semaphores? I know this can be solved by some sort of pool of shared resources, that are grabbed by consumers when they need to wait, but it would be more convenient if each request message could have its own sync object.

• Is there a lightweight multipart/form-data parser in C or C++?

  - by Hongli

  I'm looking at integrating multipart form-data parsing in a web server module so that I can relieve backend web applications (often written in dynamic languages) from parsing the multipart data themselves. The multipart grammar (RFC 2046) looks non-trivial and if I implement it by hand a lot of things can go wrong. Is there already a good, lightweight multipart/form-data parser written in C or C++? I'm looking for one with no external dependencies other than the C or C++ standard library. I don't need email attachment handling or buffered I/O classes or a portability runtime or whatever, just multipart/form-data parsing. Things that I've considered: GMime - depends on glib, so no go. libapreq - too large, depends on APR, badly documented, no unit tests. I've also looked at writing a parser with Ragel, but I can't figure out how to do it because the grammar is not static: the boundary can change arbitrarily.

• Validating an integer or String without try-catch

  - by Phil

  Ok, I'm lost. I am required to figure out how to validate an integer and String, but for some stupid reason, I can't use the Try-Catch method. I know this is the easiest way and so all the solutions on the internet are using it. I'm writing in Java. The deal is this, I need someone to put in an numerical ID and String name. If either one of the two inputs are invalid I must tell them they made a mistake. Can someone help me?

• overlay text on some else's window - HUD

  - by taglius

  I am interested in writing an app that overlays a small heads up display (HUD) over another application, in VB.NET. Does anyone have an example of this? I will need to enumerate all open windows to find the window that I want, and then overlay some text in a specific position on the window. If the user moves that window, my text will need to follow. (I will probably be painting the text in a loop over and over). Edit: nobody answered my original query - I added C# to the keywords to see if any of gurus in that language might have an answer. thanks.

• Why does the "choose files" button not work in Wordpress 2.5 when trying to upload photos?

  - by Great Kindness

  I've got Wordpress 2.5 installed on my website. It works well, but I can't get the photo uploader to work. When I'm writing a post, I click on the "Add media" button. In the "Choose File" tab, I see the "Choose files to upload" button. When I click on it, nothing happens. I searched the net and found nothing helpful. One page vaguely mentioned having the latest Flash player. I verified and confirmed that I have the latest player. Any ideas?

• API for accessing PHP documentation?

  - by Chad Johnson

  I'm done some Googling, and I've found nothing. I'm scoping out writing a plugin for an editor I use, and I am wondering whether there is a way I can access the PHP documentation via an API? For instance, I'd like to get raw access to the information (besides the comments) located here: http://php.net/file_exists. php.net seemingly uses MediaWiki which provides an API. The tutorial provides the example URL, http://en.wikipedia.org/w/api.php?action=login&format=xml. This does not work for php.net, however (http://php.net/w/api.php?action=login&format=xml). I'm just looking for a little information on how to interface with the PHP documentation.

• Is there an easy way to convert C# classes to PHP?

  - by John

  I am used to writing C# Windows application. However I have some free hosted PHP web space that I would like to make use of. I have a basic understanding of PHP but have never used it's object oriented capabilities. Is there an easy way to convert C# classes to PHP classes or is it just not possible to write a fully object oriented application in PHP? Update: There are no reliance on the .NET framework beyond the basics. The main aim would be to restructure the class properties, variable enums, etc. The PHP will be hosted on a Linux server.

• Grails / GORM, Disable First-level Cache

  - by Stephen Swensen

  Suppose I have the following Domain class mapping to a legacy table, utilizing read-only second-level cache, and having a transient field: class DomainObject { static def transients = ['userId'] Long id Long userId static mapping = { cache usage: 'read-only' table 'SOME_TABLE' } } I have a problem, references to DomainObject are being shared due to first-level caching, and thus transient fields are writing over each other. For example, def r1 = DomainObject.get(1) r1.userId = 22 def r2 = DomainObject.get(1) r2.userId = 34 assert r1.userId == 34 That is, r1 and r2 are references to the same instance. This is undesirable, I would like to cache the table data without sharing references. Any ideas? [Edit] Understanding the situation better now, I believe my question boils down to the following: Is there anyway to disable first level cache for a specific domain class while still using second level cache?

• How to organize code using an optional assembly reference?

  - by apoorv020

  I am working on a project and want to optionally use an assembly if available. This assembly is only available on WS 2008 R2, and my ideal product whould be a common binary for both computers with and without the assembly. However, I'm primarily developing on a Windows 7 machine, where I cannot install the assembly. How can I organize my code so that I can (with minimum changes) build my code on a machine without the assembly and secondly, how do I ensure that I call the assembly functions only when it is present. (NOTE : The only use of the optional assembly is to instantiate a class in the library and repeatedly call a (single) function of the class, which returns a boolean. The assembly is fsrmlib, which exposes advanced file system management operations on WS08R2.) I'm currently thinking of writing a wrapper class, which will always return true if the assembly is not present. Is this the right way to go about doing this?

• Android - Looking for an AOP solution

  - by Serj Lotutovici

  I'm writing an application that on the bottom line uses it's internal API for some manipulations. The problem is that to call any method provided by that class first I (or anybody who uses the API) have to call #prepare() and after that #cleanup(). It all worked fine until the application and the API started to grow. And the risk of not calling one of the supplied methods before or after the API is now to big to be ignored (which makes it a bug risky application). Searching for a solution I found this question. I use Google Guice in my app for other purposes, but Android doesn't support AOP, that's why a use only guice-no_aop-x.jar. So I end-up with two questions: Is there an AOP solution for android to implement the same approach that is shown in the link above? Or may be someone has an idea that will be suitable for my case? Thanks in advice!

• Obtain Update Table Lock at start of Stored Procedure in SQL Server

  - by Jim Hurne

  I'm writing a SQL Server stored procedure in which I want to lock a table for update before executing the body of the stored procedure. I don't want to prevent other processes from reading the table, but I do want to prevent other processes updating the table. Here is my first attempt: CREATE PROCEDURE someProcedure BEGIN SET TRANSACTION ISOLATION LEVEL READ COMITTED BEGIN TRANSANCTION SELECT COUNT(*) FROM TheTable WITH (UPDLOCK, TABLOCK) -- Pause procedure so that we can view the locks with sp_lock WAITFOR DELAY '00:15' -- Do stuff COMMIT END When I execute the stored procedure, and invoke sp_lock, I see that the table is indeed locked. However, it's locked with an Exclusive lock instead of an update lock: spid | dbid | ObjId | IndId | Type | Resource | Mode | Status ------------------------------------------------------------------ 63 | 10 | 233208031 | 0 | TAB | | X | GRANT How can I get an update (U) lock instead?

• Multiblog engine for asp.net

  - by Andrey

  I know, different forms of this questions were asked on this site multiple times, but I haven't seen a single answer that would satisfy my need. I need a ASP.NET based blogging engine that wouul use SQL Server as a back end and allow multiple independet blogs in one app instance. I'm writing a community website for major bank and blogging is the piece I'm not sure about. Answers to other questions include a broad spectrum from BlogEngine.NET (doesn't support multiple blogs) to CommunityServer (a beast! blogging is just asmall piece of it). I don't want to install a full-blown CRM and just use blogging, I want a blogging engine. I don't mind to buy a commercial one but I can't find one. I'm pretty much stuck, and any ideas are highly appreciated!

• Trying to load a DLL with LoadLibrary and get R6034 "An application has made an attempt to load the

  - by nonoitall

  I'm writing a wrapper program that loads Winamp input plugins. I've got it working well so far with quite a few plugins, but for some others, I get an error message at runtime when I attempt to call LoadLibrary on the plugin's DLL. (It seems to happen mostly with plugins that were included with Winamp.) A dialog appears and gives me the error code and message above. This happens, for example, with the in_flac.dll and in_mp3.dll plugins (which come with Winamp). Any ideas on how I can remedy this situation?

• Get data types from arbitrary sql statement in SQL Server 2008

  - by Christopherous 5000

  Given some arbitrary SQL I would like to get the data types of the returned columns. The statement might join many tables, views, TVFs, etc. I know I could create a view based on the query and get the datatypes from that, hoping there's a quicker way. Only think I've been able to think of is writing a .net utility to run the SQL and examine the results, wondering if there is a TSQL answer. i.e. Given (not real tables just an example) SELECT p.Name AS PersonName, p.Age, a.Account as AccountName FROM Person as p LEFT JOIN Account as a ON p.Id = a.OwnerId I would like to have something like PersonName: (nvarchar(255), not null) Age: (smallInt, not null) etc...
