• What causes POCO proxy entities to only sometimes be created in Entity Framework 4.

  - by Kohan

  I have set up my POCOs and I have marked their public properties as virtual and I am successfully getting Proxies most of the time (95%) but randomly I am getting EF return some proxies and some non-proxies. Recycling the app pool when this happens will then fix this instance of the error and it will go away for an amount of time. Then it will re-occur in some other random (it seems) place. What can cause this sort of behaviour? Thanks, Kohan

• 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.

• regular expressions: ignoring certain chars globally

  - by shi kui

  Consider it that '_'s in a number doesn't change that number's value so 1000==1_000==10_00. The Problem: given numbers like 1_244_23 1412_2 1_1111 etc..., how could I decide whether certain number appears in that collection? For example: 1244_23 yes, 11_111 yes, 1412_1 no. How could using regex to solve this? I mean, if I could tell the regex engine just ignore these '_''s when matching then this problem becomes trivial? How could I do so?

• 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!

• Grunt: Bower for development and CDN for production - is it possible?

  - by EricC

  For development, I guess it is fine to use a plugin like https://github.com/stephenplusplus/grunt-wiredep But for production I would like to use CDN where such exists. Does it exist a Grunt plugin that goes through the bower.json file and replaces this with a CDN-link from the most popular ones (and if a component is present in more than one CDN, then pick one based on rank-setting or random or something).

• Who owns forum users or are user grabbers legal?

  - by Eugene

  Hi, I am not very strong in "legal or not" questions so I hope someone can help me here. How legal is the following: I create my forum, then choose a random existing forum (not mine), take a user from that forum (username, avatar, etc) and create an identical account at my forum. I know that this is extremely hard to prove and everything but anyway: how legal are the described actions? Thanks!

• C++: type Length from float

  - by anon

  This is kinda like my earlier question: http://stackoverflow.com/questions/2451175/c-vector3-type-wall Except, now, I want to do this to a builtin rather then a user created type. So I want a type "Length" that behaves just like float -- except I'm going to make it's constructor explicit, so I have to explicitly construct Length objects (rather than have random conversions flying around). Basically, I'm going into the type-a-lot camp.
