  What does a WCF Service Library do that a regular class library doesn't? edit: i posted my own answer. Am I missing anything? Are they fundamentally both just class libraries with a few template classes added?

• Server-side auto-minify?

  - by Brendan Long

  Is there any way to automatically minify static content and then serve it from a cache automatically? Similar to have mod_compress/mod_deflate work? Preferably something I could use in combination with compression (since compression has a more noticeable benefit). My preference is something that works with lighttpd but I haven't been able to find anything, so any web server that can do it would be interesting.

  I would like a function that parses BB Code from vBulletin into a standard HTML markup. Without using the PEAR library or the PECL extension. Specifically the trouble I'm having is matching [quote=My Name]. The name 'My Name' isn't enclosed by anything and can contain spaces.

• Github post commit trigger build in Hudson with security enabled

  - by Jerry Cheung

  Github has no problem with triggering a build in Hudson with security turned off because the build is a public URL. But I'd like to be able to have logins required on Hudson so that people can't arbitrarily build. I tried looking for a HTTP basic auth method so I can include the credentials in the URL itself, but couldn't find anything like that. Has anyone used Hudson with Github and run into this problem?

• pdf viewer for pyqt4 application?

  - by japs

  Hi all, I'm writing a Python+Qt4 application that would ideally need to pop up a window every once in a while, to display pdf documents and allow very basic operations, namely scrolling through the different pages and printing the document. I've found the reportLab to create pdf files, but nothing about pdf viewers. Does anyone knows anything that might help. i was really hoping for the existence of something like the QWebView widget... thanks in advance to all

• Expected output from an RM-1501 RS232 interface?

  - by Jon Cage

  I have an old RM-1501 digital tachometer which I'm using to try to identify the speed of an object. According to the manual I should be able to read the data over a serial link. Unfortunately, I don't appear to be able to get any sensible output from the device (never gives a valid speed). I think it might be a signalling problem because disconnecting the CTS line starts to get some data through.. Has anyone ever developed anything for one of these / had any success?

• Upgrade guide for Kohana 3.0.9 (from 3.0.8)

  - by Darryl Hein

  Is there an upgrade guide for Kohana 3.0.9 from 3.0.8. I'm looking for something like what jQuery provides when they release a new version. It allows for a quick scan of the changes to notice if there's anything I could use or would change how I've done things. The resolved issues are part of this, but I'm looking for something more high level. The issues require reading everything in each issue and it's often hard to understand what's actually changed.

• REST, HTTP DELETE and parameters

  - by Chris McCauley

  Is there anything non-RESTful about providing parameters to a HTTP DELETE request? My scenario is that I'm modeling the "Are you sure you want to delete that?" scenario and eventually I end up having to pass a parameter to the delete request with "?force_delete=true" e.g. DELETE http://server/resource/id?force_delete=true If the user does not specify force_delete then I'm returning 409 Conflict - is that correct?

• Does reserving capacity incur two allocations or just one?

  - by FredOverflow

  std::vector<T> vec; // line #1 vec.reserve(100); // line #2 I am wondering if line #1 triggers a small allocation (say, memory for 10 Ts), or if the first allocation happens on line #2. Does the standard say anything about that?

• Is there a website to lookup barcodes?

  - by strange

  Hi I know there's a http://www.upcdatabase.com/ website that allows you to lookup barcodes. This website however does not return anything for thousands of normal household items. I have seen free apps on mobile phones that can do this and list the exact product name along with price comparison. Does anyone know of good websites (even commercial ones) that have a good/reliable database that one could use for lookups?

• Very simple regex not working

  - by Thomas Wanner

  I have read that to match a word inside of a string using Regular expressions (in .NET), I can use the word boundary specifier (\b) within the regex. However, none of these calls result in any matches Regex.Match("INSERT INTO TEST(Col1,Col2) VALUES(@p1,@p2)", "\b@p1\b"); Regex.Match("INSERT INTO TEST(Col1,Col2) VALUES(@p1,@p2)", "\bINSERT\b"); Is there anything I am doing wrong ?

  I have a database full of translations I'd like to generate either .po or .mo files. I'm using C#, but I could also port an implementation from PHP if one exists. I can't find any examples in any languages using anything other than GNUs gettext utilities. Does anyone know of one?

• Invoking shell commands from Squeak or Pharo

  - by squeaknewb

  How can you invoke shell commands from Squeak and Pharo? Do these environments have anything in them like the system() function in certain unix languages to run external shell commands, or the backticks (can't make them here do to the editor, but what you get when you push the key left of "1" and above "TAB") to capture the output of commands?

• simplest way to confirm payment via PayPal?

  - by Giles Bowkett

  Hi - what's the best way to simply get feedback from PayPal to confirm that your customer paid? It looks as if the answer is IPN - if so, my followup question is, can I enable IPN for only specific buttons? I don't want PayPal pinging my IPN listener for purchases that don't require any kind of IPN integration. I'm all about Agile and YAGNI, I don't want to do ANYTHING unnecessary.

• LyX - breaking long formula lines

  - by Amir Rachum

  How can I break long formulas in LyX into two (or more) lines? I know how to write several lines of equations in one "math box" but I'm looking for a solution to break lines even in the middle of a parenthesis. I'm using LyX 1.6.4 and currently, when the formula is too big, it doesn't do anything (it just doesn't print the last segment of it, which is "beyond" the page). Is this possible in LyX?
