• why my C++ output executable is so big?

  - by Vincenzo

  I have a rather simple C++ project, which uses boost::regex library. The output I'm getting is 3.5Mb in size. As I understand I'm statically linking all boost .CPP files, including all functions/methods. Maybe it's possible somehow to instruct my linker to use only necessary elements from boost, not all of them? Thanks.

• thresholding to distinguish small features in noisy data

  - by Daniel

  Hi, I'm wondering what type of threshold would work well for distinguishing features that are very small (small in the xy sense) in comparison with the full spread, if that makes sense. The graythresh() function in Matlab that uses the Otsu method doesn't work too well for my data. Otsu is a clustering method where I think the # of pixels should be similar in each class, which is not the case for me so when I employ it I get a threshold that is way too small and falls well within a lot of the background noise that remains even after filtering.

• SharePoint 2010 - Change table row /cell hover effect

  - by Sam

  In SharePoint 2010 when you hover over a column heading (i.e. to sort) in a list table, you get a hover effect, how can you supress / change this? I can see it uses OnChildColumn(this), so is there a way to modify this - either preventing the effect (e.g. when sorting can't be done on a column), or using a different background image? Also want to do the same when you hover over a cell in any of the list table's contents.

• Python/Django: log to console under runserver, log to file under Apache

  - by Justin Grant

  How can I send trace messages to the console (like print) when I'm running my Django app under manage.py runserver, but have those messages sent to a log file when I'm running the app under Apache? I reviewed Django logging and although I was impressed with its flexibility and configurability for advanced uses, I'm still stumped with how to handle my simple use-case. My apologies for not being able to find the answer elsewhere-- this is a newbie question I know.

• RESTful API: How to model 'request new password'?

  - by Jan P.

  I am designing a RESTful API for a booking application and was quite happy to see I could map all details of the application to the 4 HTTP methods. /users - GET, POST /users/({id}|myself) - GET, POST, PUT, DELETE /users/({id}|myself)/bookings - GET, POST /users/({id}|myself)/bookings/{id} - GET, POST, PUT, DELETE Example: Updating my own user uses a PUT to /users/myself. But now I found out that one thing is missing: The possibility to request a new password if I forgot my old one. Any idea how I could add this?

• Speeding up Math calculations in Java

  - by Simon

  I have a neural network written in Java which uses a sigmoid transfer function defined as follows: private static double sigmoid(double x) { return 1 / (1 + Math.exp(-x)); } and this is called many times during training and computation using the network. Is there any way of speeding this up? It's not that it's slow, it's just that it is used a lot, so a small optimisation here would be a big overall gain.

• IIS 6.0 Server and Unicode Characters

  - by Srikanth

  We are performing a pen test on a simple asp application that uses MS SQL Database. It seems for the authentication they are using dynamic constructed queries but escaping single qoutes. When we use Unicode quotes like %uFFO7,%u02b9 etc we are able to successfully inject SQL injections. Want to understand is it more a kind of configuration issue of IIS server to cannonicalize Unicode characters or the way the validation function to escape single quotes is written is the cause of the problem?
