• How can I perform an idiomatic non-recursive flatten in ruby?

  - by nasmorn

  I have a method that returns an array of arrays. For convenience I use collect on a collection to gather them together. arr = collection.collect {|item| item.get_array_of_arrays} Now I would like to have a single array that contains all the arrays. Of course I can loop over the array and use the + operator to do that. newarr = [] arr.each {|item| newarr += item} But this is kind of ugly, is there a better way?

  What would be the most performant way to prepend a single character to a multi-gigabyte file (in my practical case, a 40GB file). There is no limitation on the implementation to do this. Meaning it can be through a tool, a shell script, a program in any programming language, ...

• Is it reasonable to use OpenGL for desktop applications?

  - by JamesK89

  I've been writing a small desktop gadget-type application that displays scrolling text along the bottom of the screen (Similar to the old CNN news ticker), however the performance of GDI is just unsatisfactory (As high as 8-12% on a quad core and 20% on a single core) even after I've attempted to clean out bottlenecks. I was considering using OpenGL instead to render everything, but I don't know if that is a reasonable option to require users to have hardware acceleration for a tiny app like this. Does anybody have any input on this?

• Comma separated list of values as different rows, not as fields for one row, for an SQL INSERT

  - by Petruza

  I want to make many inserts in a single SQL statement, pretty much like INSERT INTO xxx SELECT field FROM zzz But with values I don't have in a table, and are just a list of literals. Normal way would be executing one SQL query for each value, but if there exists a standard SQL statement, or MySQL-specific, it would be great.

• Adding javascript to every occurrence of a certain HTML element

  - by Acorn

  I was wondering if there was a way of adding javascript in every occurrence of a certain HTML tag, eg. <td onmousedown=""> At the moment I just have it in every single one of my td tags in my table, but there must be a cleaner way. Something like adding javascript in the way CSS adds formatting.

• How do I solve "405 Method Not Allowed" for our subversion setup?

  - by macke

  We're serving our source code using VisualSVN running on Windows Server 2003. Recently, we split a portion of a project into a new project in it's own repository, and then linked it back to the original project using svn:externals. Since then, we've been having issues when we try to commit files with Subclipse. The error we're getting is: svn: Commit failed (details follow): svn: PROPFIND of '/svn': 405 Method Not Allowed (https://svn.ourserver.com) Googling for a while didn't really help, our config seems to be correct. It should also be noted that we've been running this server for a while no without these problems and apart from splitting the project into two repositories, no changes have been made to the server (ie, config files are the same). It should also be noted that these errors only appear when we try to check in multiple files at once. If we check in one file at a time there are no errors. Also, it only appears in Subclipse as far as we know right now, Versions.app (OS X) seems to work fine so that is our current workaround. So, the questions is how do I analyze the error to find the cause and subsequently fix it? I'm by no means a svn guru and right now I'm clueless. EDIT: It seems we can check in multiple files in the same package, but not files from multiple packages. Also, when I "split" the project into two repositories, I imported the original repository with a new name. I did not do a dump and then import that dump. Could that be the source of our issues, and if so, how would I solve that? EDIT: After some jerking around it seems as though it is indeed related to when checking in files in different repositories. If I try to do a single commit in both Repo A and Repo B (referenced by svn:externals) at the same time, I get the error. Versions.app handles this correctly, but I guess it might just be doing two commits, not a single one. Subclipse fails miserably. For now, we simply do multiple commits, one for Repo A and one for Repo B, that works just fine. If anyone smarter than me could fill in the details why this is happening, whether or not this kind of setup is stupid etc, please go right ahead.

• Why is a .net generic dictionary so big

  - by thefroatgt

  I am serializing a generic dictionary in VB.net and I am very surprised that it is about 1.3kb with a single item. Am I doing something wrong, or is there something else I should be doing? I have a large number of dictionaries and it is killing me to send them all across the wire. The code I use for serialization is Dim dictionary As New Dictionary(Of Integer, Integer) Dim stream As New MemoryStream Dim bformatter As New BinaryFormatter() dictionary.Add(1, 1) bformatter.Serialize(stream, dictionary) Dim len As Long = stream.Length

• Selecting and Copying a Random File Several Times

• The PROMOTE TRANSACTION request failed because there is no local transaction active.

  - by Mark J Miller

  Under what circumstances would I see the above message? I have a single call to SQL Server which is wrapped in a call to TransactionScope. In our development and QA environments MSDTC is turned off and the call succeeds fine. However, in our production environment with MSDTC turned on we are failing with this call. Is there something that would cause this when I am sure we are not looking at a distributed transaction call at all?

• gedit underscore as a word_character

  Is it possible to configure gedit to treat the underscore character as a word character? Currently, it appears that the editor treats "two_words" as two separate words when selecting, instead of a single word as in many other mainstream text editors.

• MySQL - Calculating fields on the fly vs storing calculated data

  - by Christian Varga

  Hi Everyone, I apologise if this has been asked before, but I can't seem to find an answer to a question that I have about calculating on the fly vs storing fields in a database. I read a few articles that suggested it was preferable to calculate when you can, but I would just like to know if that still applies to the following 2 examples. Example 1. Say you are storing data relating to a car. You store the fuel tank size in litres, and how many litres it uses per 100km. You also want to know how many KMs it can travel, which can be calculated from the tank size and economy. I see 2 ways of doing this: When a car is added or updated, calculate the amount of KMs and store this as a static field in the database. Every time a car is accessed, calculate the amount of KMs on the fly. Because the cars economy/tank size doesn't change (although it could be edited), the KMs is a pretty static value. I don't see why we would calculate it every single time the car is accessed. Wouldn't this waste cpu time as opposed to simply storing it in a separate field in the database and calculating only when a car is added or updated? My next example, which is almost an entirely different question (but on the same topic), relates to counting children. Let's say we have a app which has categories and items. We have a view where we display all the categories, and a count of all the items inside each category. Again, I'm wondering what's better. To perform a MySQL query to count all the items in each category every single time the page is accessed? Or store the count in a field in the categories table and update when an item is added / deleted? I know it is redundant to store anything that can be calculated, but I worry that calculating fields or counting records might be slow as opposed to storing the data in a field. If it's not then please let me know, I just want to learn about when to use either method. On a small scale I guess it wouldn't matter either way, but apps like Facebook, would they really count the amount of friends you have every time someone views your profile or would they just store it as a field? I'd appreciate any responses to both of these scenarios, and any resource that might explain the benefits of calculating vs storing. Thanks in advance, Christian
