• Is PHP's json_encode guaranteed to produce ASCII string?

  - by Milan Babuškov

• regarding C++ stl container swap function

  - by sm1

  I recently learned that all stl containers have swap function: i.e. c1.swap(c2); will lead to object underlying c1 being assigned to c2 and vice versa. I asked my professor if same is true in case of c1 and c2 being references. he said same mechanism is followed. I wonder how it happens since c++ references cannot be reseted.

• Is there any analog of TCPvcon which allows to close TCP connection on remote machine?

  - by Miollnyr

  Hi, I started to use SysInternals suite, and it is great. But I wonder, whether there is any analog of TCPvcon, which allows to logon to remote machine, like psexec does, and then get list of TCP connections from there (similar to pslist functionality), and then to close some of connections (similar to pskill functionality). I am speaking about windows console tools and I would like to avoid installing something on remote machine is this is possible.

• Why is it safe to use copy & paste in Flash but not in Javascript?

  - by Lenni

  I'm trying to use copy'n paste in one of my web apps and have read a few articles/SO questions about it. Most people say that using Flash is the only option since most browsers don't allow access to the system clipboard because of security concerns. I can understand this but I wonder why it is okay for Flash do this, but not for the browser. Or has it got nothing to do with security and it is simply to complicated to implement this for cross-platform browser vendors?

• ASP.NET MVC image upload store location (db vs filesystem)

  - by adrin

  I am writing web application using ASP.NET MVC + NHibernate + Postres stack. I wonder if images uploaded should be stored in database as binary blobs or on filesystem (and reference only in db). One advantage of db storage I can think of is easy backup/recovery of all data without reverting to filesystem copy tools. On the other hand I suspect that filesystem access may be faster (but is it especially when dealing with many concurrent requests?) What are your suggestions?

• Is it a good idea for me to learn Python before C or some other Compiler language?

  - by Dream Lane

  Right now I am going through MIT's introduction to Computer Science course via OpenCourseWare. As a part of this course I am learning the Python Language. I've read a lot of things about the benefits of learning C. Before I dig any deeper into Python I wonder if I will be hindered or helped by learning Python first. Do you think that I will develop any bad habits or anything like that from Python?

• How to emulate PHPs preg_split in ruby to capture offsets and delimiters?

  - by dimus

  I wonder if there is a way to get offsets and delimiters while I am splitting a string in ruby analagous to PHP preg_split: preg_split("/( |&nbsp;|<|>|\t|\n|\r|;|\.)/i", $html_string, -1, PREG_SPLIT_DELIM_CAPTURE|PREG_SPLIT_OFFSET_CAPTURE); I imagine I can achieve it by traversing string by characters or using something heavy as treetop, but I would like to use something more convenient.
