• Converting an int to an IP address

  - by User1

  Is there an easy way to convert an int to an IP address in PostgreSQL? I was able to go from IP to int using this code: SELECT inet '1.2.3.4'-'0.0.0.0' This doesn't work: SELECT 16909060::inet I didn't see anything in the documentation. Does anyone know how to do this?

• remove a varchar2 string from the middle of table data values

  - by Michelle Daniel

  Data in the file_name field of the generation table should be an assigned number, then _01, _02, or _03, etc. and then .ldf (example 82617_01.pdf). Somewhere, the program is putting a state name and sometimes a date/time stamp, between the assigned number and the 01, 02, etc. (82617_ALABAMA_01.pdf or 19998_MAINE_07-31-2010_11-05-59_AM.pdf or 5485325_OREGON_01.pdf for example). We would like to develop an SQL statement to find the bad file names and fix them. In theory it seems rather simple to find file_names that include a varchar2 data type and remove it, but putting the statement together is beyond me. Any help or suggestions apprecuiated. Something like ........... UPDATE GENERATION SET FILE_NAME (?) WHERE FILE_NAME (?...LIKE '%STRING%');?

• Limitations in running Ruby on windows7

  - by orkutscraps

  n the installation documentation to RoR it mentions that there are many limitations to running Ruby on Rails on Windows7, and in some cases, whole libraries do not work. How bad are these limitations, should I always default to Linux to code / run RoR, and is Iron Ruby expected to fix these limitations or are they core to the OS itself?

• How to implement low pass filter using java

  - by chai

  Hello Everyone, I am trying to implement a low pass filter in Java. My requirement is very simple,I have to eliminate signals beyond a particular frequency (Single dimension). Looks like Butterworth filter would suit my need. Now the important thing is that CPU time should be as low as possible. There would be close to a million sample the filter would have to process and our users don't like waiting too long. Are there any readymade implementation of Butterworth filters which has optimal algorithms for filtering. Regards, Chaitannya

• Why are configuration arrays acceptible parameters in PHP and Javascript?

  - by RenderIn

  In most other OO languages it would be sacrilege to have each function receive a single associative array of Objects rather than enumerating each in the method signature. Why is it acceptable and commonly used in most popular frameworks for both of these languages to do this? Is there some justification beyond wishing to have concise method signatures? I do see a benefit in this -- that the API could remain unchanged as new, optional parameters are added. But Javascript and PHP already allow for optional parameters in their method signatures. If anything, it seems like Java or another OO language would benefit from this more... and yet I rarely see this pattern there. What gives?

• How to treat compressed folders as files using ShellObject from WindowsAPICodePack?

  - by JustABill

  I am trying to implement a filesystem browser using the WindowsAPICodePack for C# (.Net 4), and it works pretty well, except that the ShellObject system treats zip files as folders, whereas I'd prefer they be files. Is there some way I can force it to work this way? The low-level interop it does is beyond me. As far as I can tell, internally it asks if the item is a Folder or a Filesystem element. It then uses this (and some type checks) to figure out what it actually is. Is it safe to force it to treat it as a file if it's Compressed? Or do I have to do something else?

• ssh-2 rsa body format?

  - by high6

  Is there any documentation on what the bignums in the body are? Like here is an example pubkey. ssh-rsa AAAAB3NzaC1yc2EAAAABJQAAAIBMgigwcBaB3sqogC/yVPANQJKjMwOvrdOKhBIVlI2eOIq6FEyzNI8cbRDbHo5muipun922bLoV+p/dPZ2/8wJ+zugLM8eCdsr+VbYZ3T5wb7bjd2swePOWtffnsXnHiP8aWyRj64vd/mRPR1gYErg8vb7vM5c4B2ANKHs/rP65Bw== rsa-key-20100514 It contains 3 bignums with the sizes 7, 1, 128. Now I am assuming the 128 is the key while the 7 is the shared. But what about the other one? Also the privkey contains a lot more bignums which I have no idea what they are.

• Is it possible to integrate user databases between Drupal and an ASP&SQL Server platform?

  - by hecatomber

  We have a game project designed on ASP&SQL Server, and we need to integrate it's user database with Drupal. This would be easier from Project to Drupal (since there is user_save and user_delete functions available globally by using drupal bootstrap) but I'm not sure if we can execute PHP functions on an ASP platform. Is there any documentation for this kind of problems? What do you suggest?

• Prevent Java from parsing the command line parameters

  - by User1

  Would like to make anapplication in Java that will not automatically parse parameters used on the command-line. Currently, java requires public static void main(string[]) as the entry point signature. I would like just a single string that I parse myself. Can this be done at all? Here's an example: java MyProgram.class Hello World I would want it to give me Hello World without requiring quotes around that string. I would even settle for java giving me the entire java MyProgram.class Hello World. I'm thinking this is something beyond Java and has more to do with the shell.

• SVN: Recurisvely add files?

  - by Mark

  I'm trying svn add *.py --force As the documentation suggests, but I know for a fact it's missing files nested in deeper folders. Why? Is there a standard way to do this with other unix commands too? */*.py will nab a few more files, but it's kind of a pain in the butt to do this for every possible depth.

• How are Cassandra's 0.7 Secondary Indexes stored?

  - by user574793

  We have been using Cassandra 0.6 and now have Column Families with millions of keys. We are interested in using the new Secondary Index feature available in the 0.7 but couldn't find any documentation on how the new index is stored. Is there any disk-space limitation or is the index stored similar to keys in that it's spread over multiple nodes? I've tried combing through the Cassandra site for an answer but to no avail.

• Getting back into C/C++ after several years

  - by themaninthesuitcase

  While at university I started my first programming with ANSI C, before we moved onto Java later in the course. Now I would like to go back to (re)learning C and C++ again to allow me to contribute with open source projects and also to expand my CV and improve my career prospects. Currently I mostly program in VB.net (I know I know, I try to not do things the nasty way you can with this) and am slowly picking up C# as I get some time at work. I also use a bit of java for Android dev. While I realise just doing it is the best way to learn, my exercise ideas are usually either trivial or beyond my current skills. What are some good sources for this initial relearn, I intend to possibly start helping with Chromium as other people seem to think this a good place to get started in OS. Basically any help getting back into this would be appreciated.

• Out of Memory Matlab Error

  - by Hani

  Dears. I am using Matlab 2009b and having an out of memory error. I read other posted sol but they are not useful for me. I am sure that i am doing things right but i must use very huge amount of array sizes. I think that the problem lies beyond the fact that Matlab does not enable an array to be in more than one OS block. I am using Windows 7. Is there a way to get rid of this problem. For example can i increase the array block that Matlab uses in Windows 7? Thanks...Hani Almousli
