• converting factored number to decimal in MS SQL

  - by LS

  I need to convert a number which gives decimals in factored format in to decimals, i.e. 11.16 is 11.5 in decimal. This is because 16 is in base of 32 and 11.16 should be read as 11+16/32 = 11.5 I get 11.16 as a string and I need to change it to 11.5 as numeric in MS SQL(2005) database. Any shorter way of doing this rather than splitting strings,converting to numerics,maths,convert to string, concatenate and then convert to numeric?

• Bash: how to process variables from an input file?

  - by gilgongo

  I've got a bash script that reads input from a file like this: while IFS="|" read -r a b do echo "$a something $b somethingelse" done < "$FILE" The file it reads looketh like this: http://someurl1.com|label1 http://someurl2.com|label2 However, I'd like to be able to insert the names of variables into that file when it suits me, and have the script process them when it sees them, so the file might look like this: http://someurl1.com?$VAR|label1 http://someurl2.com|label2 So $VAR could be, for example, today's date, producing an output like this: http://someurl1.com something label1 somethingelse http://someurl2.com?20100320 something label2 somethingelse

• Using a CSV/Text-File as a RecordSource for a Report

  - by Falcon

  I need an Access Report to use a CSV-File as a RecordSource. I have searched and tried many things, yet, I've found no way to achieve this. A temporary table in some other database is not an option. I've been trying to use a DAO RecordSet, but while I can read the RecordSet just fine I cannot set it as the report's RecordSet and I cannot use its Name as the RecordSource Property as both approaches lead to an error. Please help me find a way!

• Is it possible to decode an MMS+WMA2 stream using audio units on the iPhone?

  - by Nick Toumpelis

  I am not sure whether audio units can work as codecs in a streaming audio scenario on the iPhone. I've read in various places that it can be done, but I haven't seen any examples or proper documentation for that. Instead, I find that most of the apps released have utilised ffmpeg and libmms. I appreciate any help or pointers you can give me.

• for x in y, type iteration in python. Can I find out what iteration I'm currently on?

  - by foo

  Hi, I have a question about the loop construct in Python in the form of: for x in y: In my case y is a line read from a file and x is separate characters. I would like to put a space after every pair of characters in the output, like this: aa bb cc dd etc. So, I would like to know the current iteration. Is it possible, or do I need to use a more traditional C style for loop with an index?

• Entity binding WPF

  - by morphsd

  I'm doing some auction sale app and I'm new to Entity Framework. I used quickest way to create and bind Wpf control and entity(wizard and drag and drop) so VS2010 generated a lot of code for me. Now I have a problem... WPF control isn't syched to my entity. I read some articles and I understood that I have to use IObservable. Is there an easy way to do that without writing that generated code manually?

• iPhone team dev, do we all need the same OS?

  - by aruwanwan

  I´m just starting iPhone development with a small team of (really young and naive) colleagues, we all are fairly new to OS X, my question is: If we are planning to develop for every iPod Touch/iPhone out there (not the iPad, I read that thing requires Snow Leopard), what problems will we encounter when sharing code (and making commits) if we all have a combination of Leopard and Snow Leopard systems?

• Generic JSON parser in .NET / WPF?

  - by niklassaers

  I've read lots of tutorials on how to deserialize a JSON object to an object of a particular using DataContractJsonSerializer. However, I'd like to deserialize my object to a Dictionary consisting of either Strings, Arrays or Dictionaries, such as System.Json does with SilverLight when I say JsonObject.Parse(myJSONstring). Is there an equivalent to System.Json that I can use in my WPF project? (just a short background: I'm fetching JSON objects that have way to much info, and I just want to use a little bit to fill out a String array) Cheers Nik

• Bash: Is it ok to use same input file as output of a piped command?

  - by Amro

  Consider something like: cat file | command > file Is this good practice? Could this overwrite the input file as the same time as we are reading it, or is it always read first in memory then piped to second command? Obviously I can use temp files as intermediary step, but I'm just wondering.. t=$(mktemp) cat file | command > ${t} && mv ${t} file

• Real world examples of tree structures

  - by Arec Barrwin

  I'm looking for some examples of tree structures that are used in commercial/free software projects, modern or old. I can see examples on wikipedia, but I am looking for more concrete examples and how they're used. For example primary keys in databases are (from what I've read) stored in BST structure or a variation of the BST (feel free to correct me on this) My question isn't limited Binary Search Trees (BSTs), it can include any variation such as red-black, AVL and so on.

• How to do both ways integrations across different perfoce depots?

  - by Sorin Sbarnea

  I would like to know how we are supposed to do integration between different perforce servers/depots. I'm looking for a solution that would allow us to do both-ways integrations. Currently I found some information on Using Remote Depots article where they say how to map the remote depot as read only. Is there the only solution to do mappings on both servers? - this means that I could not use a single branch spec to do both ways integrations.

• Good ways to map a 2D side shooter (somewhat like liero, or soldat)

  - by Blaze

  I'm wondering what way would be best to render a 2D map for a shooter (these will be static maps) similar to Soldat. Multiple options I've considered are a tile based map (stored in txt files), or just creating different classes for the different terrains I plan to use and creating a data structure to read/store them in a file. (I want to also be able to include things like jumping/running on walls, sliding down walls/slopes ect) I feel like there must be a better way than either of these, but haven't been able to find definitive information :/ Thanks :)
