• Extract number from string in Ruby

  I'm using this code: s = line.match( /ABCD(\d{4})/ ).values_at( 1 )[0] To extract numbers from strings like: ABCD1234 ABCD1235 ABCD1236 etc. It works, but I wonder what other alternative I have to to this in Ruby?

• Getting the position of the element in a list when it's drag/dropped (ui.sortable)

  - by Wurlitzer

  Hi, I have a sortable list like this one: http://jqueryui.com/demos/sortable Is it possible to get the start and end position of the element in the list, when it has been moved? I'm talking about their position number, in the list. For example, if I move element 2 to position 5 in the list, I'd like to assign those two numbers to variables. I'm new to jQuery - any help would be much appreciated.

• Why can't c# calculate exact values of mathematical functions

  - by Timo Willemsen

  Hey everyone, Why can't c# do any exact operations. Math.Pow(Math.Sqrt(2.0),2) == 2.0000000000000004 I know how doubles work, I know where the rounding error is from, I know that it's almost the correct value, and I know that you can't store infinite numbers in a finite double. But why isn't there a way that c# can calculate it exactly, while my calculator can do it. Edit It's not about my calculator, I was just giving an example: http://www.wolframalpha.com/input/?i=Sqrt%282.000000000000000000000000000000000000000000000000000000000000000000000000000000001%29%5E2 Cheers

• Regular expression to extract text between two sets of characters (Javascript)

  - by optician

  I would like to extract some text between two points in a string, in Javascript Say the string is "start-extractThis-234" The numbers at the end can be any number, but the hyphens are always present. Ideally I think capturing between the two hypens should be ok. I would like the result of the regex to be extractThis

• Performance Cost of a Memcopy in C/C++

  - by Cenoc

  So whenever I write code I always think about the performance implications. I've often wondered, what is the "cost" of using a memcopy relative to other functions in terms of performance? For example, I may be writing a sequence of numbers to a static buffer and concentrate on a frame within the buffer, in order to keep the frame once I get to the end of the buffer, I might memcopy all of it to the beginning OR I can implement an algorithm to amortize the computation.

• Converting a string into a list in Python

  - by Sam

  I have a text document that contains a list of numbers and I want to convert it to a list.

Does anyone know of an easy way to do this in Python? 1000 2000 3000 4000 to ['1000','2000','3000','4000']

• Python: concatenate generator and item

  - by TarGz

  I have a generator (numbers) and a value (number). I would like to iterate over these as if they were one sequence: i for i in tuple(my_generator) + (my_value,) The problem is, as far as I undestand, this creates 3 tuples only to immediately discard them and also copies items in "my_generator" once. Better approch would be: def con(seq, item): for i in seq: yield seq yield item i for i in con(my_generator, my_value) But I was wondering whether it is possible to do it without that function definition

• Can the .NET MethodInfo cache be cleared or disabled?

  - by Anton

  Per MSDN, calling Type.GetMethods() stores reflected method information in a MemberInfo cache so the expensive operation doesn't have to be performed again. I have an application that scans assemblies/types, looking for methods that match a given specification. The problem is that memory consumption increases significantly (especially with large numbers of referenced assemblies) since .NET hangs onto the method metadata. Is there any way to clear or disable this MemberInfo cache?

• Fastest way to find the largest power of 10 smaller than x

  - by peoro

  Is there any fast way to find the largest power of 10 smaller than a given number? I'm using this algorithm, at the moment, but something inside myself dies anytime I see it: 10**( int( math.log10(x) ) ) # python pow( 10, (int) log10(x) ) // C I could implement simple log10 and pow functions for my problems with one loop each, but still I'm wondering if there is some bit magic for decimal numbers.

• System loops using non-integers?

  - by mary

  I wrote a .sh file to compile and run a few programs for a homework assignment. I have a "for" loop in the script, but it won't work unless I use only integers: #!/bin/bash for (( i=10; i<=100000; i+=100)) do ./hw3_2_2 $i done The variable $i is an input for the program hw3_2_2, and I have non-integer values I'd like to use. How could I loop through running the code with a list of decimal numbers?

• Is it possible to create a patch using a set of changelists?

  - by webXL

  Problem: 2 projects shared trunk and were updating some of the same files. Now one project needs to be released, so a new branch was created from a checkpoint before the projects started. I have a list of just my changelist numbers from the mainline. Using that I can generate a list changed files and diff output using a script with a series of 'p4 describe #' commands. Can I reformat that output and apply it to the new branch somehow?

• Font Size Based on Char or Number Data

  - by debaucheryx

  I am trying to find a way to display numerical digits as a larger font size than chars on a website (not my idea!). The reason for this is to make the numbers stand out. I have looked for a font that would satisfy this without coding but I could not find any. Also, I don't want to slow down the website by having the font coverted to an image. Does anyone have a solution to this ridiculous problem?

• Extract two double Values from String using RegEx in Java

  - by tzippy

  I am reading a file by line and need to extract latitude and longitude from it. This how lines can looks: DE 83543 Rott am Inn Bayern BY Oberbayern Landkreis Rosenheim 47.983 12.1278 DE 21147 Hamburg Hamburg HH Kreisfreie Stadt Hamburg 53.55 10 What's for sure is, there are no dots surrounded by digits except for the ones representing the doubles. Unfortunately there are Values without a dot, so it's probably best to check for numbers from the end of the String. thanks for your help!

• Advantages and disadvantages of including PDB files with your release application

  - by zeocrash

  I've got a VB.net application. Currently the release version of the application is produced without a PDB file. This gives me error logs lacking useful details such as line numbers. I'm looking at including the PDB files with future builds but i'd like to know what the advantages and disadvantages of this are (performance wise, size wise, code security wise)
