• Aiming Netbeans code snippets

  - by rwallace

  Not quite sure whether I'm using the right terminology here, but Netbeans has a very nice feature where e.g. if you start typing for it will offer to write a code fragment looping over an array or list, basing it on the name and type of an array or list variable actually in scope. If more than one such variable is in scope it will guess, sometimes correctly and sometimes not. Is there a way to aim this feature at the correct array/list variable?

• How to select records as columns in SQL

  - by Leigh

  Hi, I have two tables: tblSizes and tblColors. tblColors has columns called ColorName, ColorPrice and SizeID. There is one size to multiple colors. I need to write a query to select the size and all the colors (as columns) for a that size with the price of each size in its respective column.

• Play video while downloading into local disk [AIR]

  - by vincentma

  Hello guys, Using NetStream, I can create progressive video player. But can I save the downloaded chunk to my local disk in AIR?? My first idea is that, download part of file into local disk, let NetStream pointing to that file, and then appends the chunks to that file (FileMode.APPEND) periodically. But it does not work and seems that NetStream would 'lock' the file preventing write operation. Any ideas?

• How to number the ls output in unix?

  - by Snehal

  I am trying to write a file with format - "id file_absolute_path" which basically lists down all the files recursively in a folder and give an identifier to each file listed like 1,2,3,4. I can get the absolute path of the files recursively using the following command: ls -d -1 $PWD/**/*/* However, I am unable to give an identifier from the output of the ls command. I am sure this can be done using awk, but can't seem to solve it.

• SWI-Prolog Semantic Web Library and Python Interface

  - by John Peter Thompson Garcés

  I want to write a Python web application that queries RDF triples using Prolog. I found pyswip for interfacing Python with SWI-Prolog, and I am currently looking into SWI-Prolog's RDF capabilities. I am wondering if anyone has tried this before--and if anyone has: what did your setup look like? How do you get pyswip to work with the SWI-Prolog semantic web library? Or is there another Python-Prolog interface that makes this easier?

• Is there a language that encourages good coding practices?

  - by Darrell Brogdon

  While I love PHP I find its biggest weakness is that it allows and even almost encourages programmers to write bad code. Is there a language that encourages good programming practices? Or, more specifically, a web-related language that encourages good practices. I'm interested in languages who have either a stated goal of encouraging good programming or are designed in such a way as to encourage good programming.

• jquery - detect if selector returns null

  - by peirix

  What is the best way to detect if a jQuery-selector returns an empty object. If you do: alert($('#notAnElement')); you get [object Object], so the way I do it now is: alert($('#notAnElement').get(0)); which will write "undefined", and so you can do a check for that. But it seems very bad. What other way is there?

• Is there something like the OllyDbg / SoftICE disassembler + debugger for java?

  - by Ran Biron

  Is there a utility similar to OllyDbg / SoftICE for java? I.e. execute class (from jar / with class path) and, without source code, show the disassembly of the intermediate code with ability to step through / step over / search for references / edit specific intermediate code in memory / apply edit to file... If not, is it even possible to write something like this (assuming we're willing to live without hotspot for the debug duration)?

• Working with arrays passed byref

  I would like for someone to explain this to me: function myFunction(array){ array = $.grep(array, function(n,i){return n > 1 }); } var mainArray = [1,2,3]; myFunction(mainArray); document.write(mainArray) // 1,2,3, but i'm expecting 2,3 but if i do something like array[3] = 4; in place of the $.grep line, i get 1,2,3,4. Shouldn't mainArray become the new array created by $.grep?

• What is the difference between "someValuesFrom" and "allValuesFrom"?

  - by ahmed

  In descriptive logic, what is the difference between "someValuesFrom" and "allValuesFrom"? In other words, the difference between (limited existential quantification) and (value restriction). For example, consider this picture: I have used the photoshop because I can't write some symbols. Is there any way to simplify the concept of somevaluefrom and allvaluesfrom?
