• Scala: Can't catch exception thrown inside a closure

  - by Dmitriy

  Disclaimer: absolute novice in Scala :( I have the following defined: def tryAndReport(body: Unit) : Unit = { try { body } catch { case e: MySpecificException => doSomethingUseful } } I call it like this: tryAndReport{ someCodeThatThrowsMySpecificException() } While the call to someCodeThatThrowsMySpecificException happens just fine, the exception is not being caught in tryAndReport. Why? Thank you!

• Subroutine to apply Daylight Bias to display time in local DST?

  - by vfclists

  UK is currently 1 hour ahead of UTC due to Daylight Savings Time. When I check the Daylight Bias value from GetTimeZoneInformation it is currently -60. Does that mean that translating UTC to DST means DST = UTC + -1 * DaylightBias, ie negate and add? I thought in this case for instance adding Daylight Bias to UTC is the correct operation, hence requiring DaylightBias to be 60 rather than -60.

• New Bluetooth API question

  - by Ralphz

  I have written a small app that puts my bluetooth in discoverable mode for a long time (G1 - API 1.6).

I'm ok with saying ok for the first time but not every 300s :)

• Installing Ruby 1.9.1 on Ubuntu?

  - by Björn

  I wonder about installing the latest version of Ruby on Ubuntu 9.04. Now I can run through the ./configure and make stuff fine, but what I wonder about: how to avoid conflicts with the packaging system? For example if some other package I install depends on Ruby, wouldn't the package manager install the (outdated) Ruby package and in the worst case overwrite my files? So I think I need some way to tell Ubuntu that Ruby is in fact already installed?

• How to configure .NET's WebBrowser to obey the current language settings

  - by Ross Goddard

  I am using the System.Windows.Forms.WebBrowser object for displaying and printing a report. Unfortunately the Page Setup dialog is not obeying the language settings on the user's computer and all of the text is coming up in English. The .NET dialogs for opening and saving a file are coming up in the correct language but not the Printing/Page Setup dialogs for the Web Browser.

• Drupal: assign block to a specific content type

  - by bert

  I made a customized template called node-mynode.tpl.php Whenever a node of type mynode is requested, then node-mynode.tpl.php is automatically used. However, now user wants to see a specific menu block in this case. Question: How can I assign a block to a specific content type? Hint: I have started to look at URL aliases with Pathauto. I suspect one solution may lie in this direction.

• What's faster? select [object] or select new {[object].value1, [object].value2} with linq

  - by Darcy

  I was hoping some of you guru's out there know the answer to this question. Which is faster? A or B A: var item = from d in database select d; B: var item = from d in database select new {d.item1, d.item2}; SEEMINGLY, it seems like selecting part of the table object would be faster than selecting the entire object, but something tells me its not necessarily the case.

• Why does a Non-existant page returns 302 status when using a custom 404 page in asp.net

  - by webdevbytes

  I have setup custom 404 page custom404.aspx that returns a 404 Not Found error correctly, however the non-existant page that was initially requested returns a 302 Found status. So when I test thispagedoesnotexist.aspx, it returns a 302 Found then the custom404.aspx loads and returns a 404 Not Found status. I want to make sure that search spiders/bots understand that the requested page does not exist and should not show up in any search results. Is this the case? Cheers

• Resize form based on if subform visible

  - by dmr

  I have a form with a subform on it. If subform contains no records, it's visible property is false. In that case, I'd like the outer form to shrink so that there isn't a big empty space where the subform was. The long way to do this would be by setting the position for all the controls on the form based on whether the subform is visible. However, is there an easier way to do this (maybe with the can grow/ can shrink property)?

• Eclipse: view a document using custom spacing, save using the file's spacing

  - by Steven Sproat

  I have a silly use case for eclipse: At work, they use 2 spaces for a tab character. Indentation looks really squashed and I'm finding it obstructs readability. Now, I can't set Eclipse to use 4 spaces for a tab as it'll edit any files I change, and obviously don't want to violate the coding standards. So, can I have a custom view onto my document, with saving maintaining the original spacing? Cheers

• JBoss Service with SSL and Protocol Buffers

  - by mlaverd

  Hello everyone, I'm interested in building a JBoss service. Because I'm reusing some existing code, the service must be able to talk SSL/TLS and Protocol Buffers. The documentation I see on the JBoss wiki makes it look like services have their transport and data interpretation handled by JBoss itself. Is it really the case? How could I implement this requirement? Regards, M-A

• CodePage ID to CodaPage name: GetEncoding equivalent in Delphi?

  - by Steve

  Hello all, I'm looking for a Win32 equivalent of the .Net Encoding.GetEncoding Method to be used in Delphi7. What I would like to achieve is to convert a Codepage ID (ie.: 28592) to a Codapage name (iso-8859-2 in this case). I've found a Win32 function called GetCPInfoEx, but that returns a long CodePage name, and I need the short one, like the ones listed on this page: (see Name column) http://msdn.microsoft.com/en-us/library/system.text.encoding.aspx Thank you!

• Automatically open files given as command line arguments in Python

  - by mk

  I have a lot of Perl scripts that looks something like the following. What it does is that it will automatically open any file given as a command line argument and in this case print the content of that file. If no file is given it will instead read from standard input. while ( <> ) { print $_; } Is there a way to do something similar in Python without having to explicitly open each file?

  I'm considering optimal open source solution for storing xml documents with further querying on them effectively. Amount of data will be small.
