• Does anyone have experience simultaneously running a Drupal and Wordpress site and redirecting some

  - by DKinzer

  This is a really weird question and I apologize: I've been asked if it's possible not to import our blog from Wordpress to Drupal but just keep it in Wordpress as an archive and re-direct our users say from hostname/blog/... to hostname/wordpress/... when a URL matches the Wordpress URL pattern. I've never heard of anyone trying this and I'm wondering about pitfalls and whether or not it's even possible. Thanks! D

• Editing an UIImage

  - by wwrob

  I have an UIImage that I want to edit (say, make every second row of pixels black). Now I am aware of the functions that extract PNG or JPEG data from the image, but that's raw data and I have no idea how the png/jpeg files work. Is there a way I can extract the colour data from each pixel into an array? And then make a new UIImage using the data from the array?

• Is it possible to package an exe into an NSIS generated installer which runs first?

  - by nbolton

  Is it possible to generate an NSIS installer (using a .nsi) which packages an exe (let's say foobar.exe) which is then run before the installer actually installs the program as normal? I assume it'd have to extract the exe to a temp dir before running it, which is fine. It must be run before the main install however.

• How can I debug expect_before behaviour

  - by itj

  I am relatively new to TCL / expect and mostly modifying existing code. expect_before doesn't seem to do what I expect (which is fine) but I can't work out how to debug it. I have used -d option and am now using exp_internal -f "argh.log" 1 to create a log file, but it isn't helping me. expect_before -info seems useful, but I am not able to grab / display the output (I did say I was new to TCL)

• mysql insert multiple rows, return rows that failed

  - by Glenn

  When I try to insert (lets say) 30 rows in my table. For example INSERT INTO customers(cust_name, cust_address, cust_city, cust_state, cust_zip, cust_country) VALUES( 'Pep E. LaPew', '100 Main Street', 'Los Angeles', 'CA', '90046', 'USA' ), ( 'M. Martian', '42 Galaxy Way', 'New York', 'NY', '11213', 'USA' ), ... ; And cust_name has to be unique. How can I then identify the records that failed to insert because their cust_name already exists? Is it possible to return them?

• Powerbuilder "runtime"

  - by dariopy

  I've copied (not installed) a system developed with Powerbuilder, from a salvaged hard drive. I want to run the application, but of course, it asks for several DLLs and stuff like that, which are not registered in my current system. My question: is there a procedure to install a "powerbuilder runtime", so to say, in order to run the application?

• Ruby on Rails server running in production mode shouldn't show any error details?

  - by Jian Lin

  I thought I read that when a Ruby on Rails server is running in production mode, it won't say so much about an error (the details, showing the code)... but I just try to run the server using ruby script/server -e production and add a <%= x %> with the local variable x undefined. It showed a lot of error details including the code... is there a way to make it look better?

• Rails: Easiest way to provide file downloads?

  - by Schroedinger

  G'day guys, currently have almost finished writing a rails application that allows a CSV download of the database. This is generated when the index is first viewed. Is there an easy way to insert a link to a helper that returns a CSV document? That is to say is it easy to insert links to helpers? This would make a lot of problems I've been having much easier

• Makefiles, symlinked folder & relative paths

  - by l.thee.a

  Let say I have the following folders: /A/C /D/B/E /D/B/C (this is a symlink to /A/C created by ln -s) When one of the makefiles tries to use the path /D/B/C/../E it gets a "no file or directory" error. I understand why this happens; /A/E does not exist. However I have to use symlinks to populate the B folder and create the build tree (very long story). Any ideas?

• Throwing cats out of windows

  - by AndrewF

  Imagine you're in a tall building with a cat. The cat can survive a fall out of a low story window, but will die if thrown from a high floor. How can you figure out the longest drop that the cat can survive, using the least number of attempts? Obviously, if you only have one cat, then you can only search linearly. First throw the cat from the first floor. If it survives, throw it from the second. Eventually, after being thrown from floor f, the cat will die. You then know that floor f-1 was the maximal safe floor. But what if you have more than one cat? You can now try some sort of logarithmic search. Let's say that the build has 100 floors and you have two identical cats. If you throw the first cat out of the 50th floor and it dies, then you only have to search 50 floors linearly. You can do even better if you choose a lower floor for your first attempt. Let's say that you choose to tackle the problem 20 floors at a time and that the first fatal floor is #50. In that case, your first cat will survive flights from floors 20 and 40 before dying from floor 60. You just have to check floors 41 through 49 individually. That's a total of 12 attempts, which is much better than the 50 you would need had you attempted to use binary elimination. In general, what's the best strategy and it's worst-case complexity for an n-storied building with 2 cats? What about for n floors and m cats? Assume that all cats are equivalent: they will all survive or die from a fall from a given window. Also, every attempt is independent: if a cat survives a fall, it is completely unharmed. This isn't homework, although I may have solved it for school assignment once. It's just a whimsical problem that popped into my head today and I don't remember the solution. Bonus points if anyone knows the name of this problem or of the solution algorithm.

• How do you return stolen packets back to Netfilter

  Let's say I have intercepted a packet from Netfilter and subsequently returned NF_STOLEN. At some point I want to re-inject that packet back to, in this case, the TCP stream it came from.

• Insert the lowest possible unique positve integer in an atomic fashion in MySql

  - by Jason Christa

  Say I have a table with a unique positive integer field. I currently have rows with id's of [1, 2, 3, 4, 5, 8, 12, 35]. Is there a insert query that I could write that would assign the id field to the lowest unique positive integer (in this case 6)? It would have to do this atomically so there isn't the possibility of concurrent inserts wiping out each other or failing.

• MySQL create view from concat value

  - by cnotethegr8

  Lets say I have a table as follows, +----+-------------+ | id | value | +----+-------------+ | 1 | aa,bb,cc,dd | | 2 | ee,ff,gg,hh | +----+-------------+ I want to be able to search this table to see if id = 1 AND value = 'cc'. Im assuming a good way of doing this is to grab the id = 1 row and split its values into separate rows in a new view. Something like, +-----+ | val | +-----+ | aa | | bb | | cc | | dd | +-----+ I would like to do all of this in MySQL. How can i do this, and is there possibly a better way to do it?

• Django - urls.py - Filenames with a hash/pound (#) sign?

  - by miya

  I'm using django and realized that when the filename that the user wants to access (let's say a photo) has the pound sign, the entry in the url.py does not match. Any ideas? url(r'^static/(?P<path>.*)$', 'django.views.static.serve', {'document_root': MEDIA_ROOT}, it just says: "/home/user/project/static/upload/images/hello" does not exist when actually the name of the file is: hello#world.jpg Thanks, Nico

• Dynamically loading jQuery library from a custom component and ensuring only one instance.

  - by Paul Lucas

  Say I have a web component that uses jQuery and I want to distribute it as a packaged component. I need a way to ensure that the jQuery library is available on or after the page loads, but I also want to check that the containing html page, or another unknown component that may reference jQuery hasn't already added the library to the page. At the moment the best example I've seen is this http://www.squidoo.com/load-jQuery-dynamically It would need a little tweaking, but I was wondering if there were any other best practices.
