 | In linux/unix/bsd type OSs, you can chant kill -9 [I]parentProcID[/I] from the command line. No clue on Windows OSs Usually, you would call wait() or some variant after sending the kill signal to the child, then die gracefully yourself (sys.exit(0), maybe; or exit with the exit status of the child; …  |
| | I don't have a compiler set up on this laptop, so I'm working by eye. Thus, I may have the comparisons reversed on lines 9 and 15 (?) ... and for that matter maybe one lines 7 and 13 (?). But here's approximately what I would do:[CODE]int lessthan(const void *a, … |

| | Please tell us how the program is invoked, what happens, what is the exact failure mode, and text of failure. Can you (just) process all the files? That is: If you comment out the list1.append(tokens[1] etc, and just throw the results away, does the program run to completion? What happens …  |
| | You just have to look at the code: When you call the function what is the argument that is passed in? You can think of each invocation (whether called from 'outside' or from 'inside') as a distinct function. This is the function:[CODE]def func(depth): if depth > 0: return function(depth - …  |
| | Is it as simple as word.txt versus word[B]s[/B].txt? Try this:[CODE]import os os.listdir('.')[/CODE] If that gets an unexpected result, it should give you a good clue.  |
| | In my (humble?) opinion, there is very little value to the SOAP protocol. Some, maybe, but RESTful behavior offers pretty much the same thing with a lot less hassle. |
| | Some of the audio formats are published, some not. Most of them have at least some information about the format available via online searches. Some search like [I]type[/I] format (for [I]type[/I] being whatever data format you are interested in. As I recall it, mp3 files have a nice regular format … |

| | You need a system that creates an ordinal value for each hand (the rank of the hand) and you just compare the ranks. The trick, then, is to write that function. I'm not a poker expert, but I'd do something like: Recognize all the possible ways the hand can be … |
| | I think your comparison of B with A has already been done when you compared A with B. The cost of doing this work is [B]O[/B](n^2), which is not small for your data set. If you can reduce it by a factor of 2, it is probably worth doing. Thus, … |

| | From your description "... a varying number of fields and values..." I would think you want a non-relational data store. Depending on things you didn't say, you might want to use your described structure, using pickle/unpickle to persist it to disk; or you might want to go with something like … |

| | snippsat has it right. You can, however, manipulate global variables from inside a function if you declare them global, though for most purposes this is not a good idea. For instance[CODE]def makeage(): global age # set age = some calculation here # and the global age is altered[/CODE]You have a … |
| | You need to specify the problem much more completely, and you need to try to do the work yourself, at least some, or we won't help. What is a "time table" and what does it mean to generate one? When you post your first code, be sure to use the … |
| | You need that [iCODE]root[/iCODE] and [icode]root/module2[/icode] be in [icode]sys.path[/icode] which can be done like this in [iCODE]somescript[/iCODE]:[CODE]import os import sys rootpath = os.path.dirname(os.path.abspath(os.curdir)) sys.path.append(rootpath) mod2path = os.path.join(rootpath,'module2') sys.path.append(mod2path) import common import someotherscript[/CODE]Of course you also need to be sure that all these things exist; it would be nice not to … |

| | The language is almost irrelevant: Some jobs need one, some another (and then only to get your first position in the firm). What matters is professionalism, background, personality, and things that schools mostly don't teach...[B]and[/B] the ability to do "the job" in one or more languages, which you do need … |
| | Level 0 is what amount of detail? (What [B]is[/B] the data?) Where does the data start? (Who asks or tells?) What stage(s) does the data go through on the way to the final sink/end? What is the end result? (Who receives or stores?) |
 | Yes, as long as you are thoughtful/careful about what you mean by "sort of substring". [url]http://dev.mysql.com/doc/refman/5.0/en/string-functions.html[/url]. Generally speaking, you may find it better to do the comparison outside the database, unless you are doing some kind of matching SELECT |

The steps are [LIST=1] [*]read the file into memory [*]update the memory version of the file [*]write the file to a new name (maybe [iCODE][I]original[/I].tmp[/iCODE] or the like) [*]rename the original file (maybe … |
| | This is bash running on OS/X. The pv command is "pipeviewer", which invoked -L1 limits throughput to 1 byte per second. Using two windows, first I chanted [iCODE]ps -l[/icode] in window 2. The result is as seen below, and is the base case of two bash shells running. [code]508% ps … |

 | Re: Matrix mess Awsome! As a general rule, non-template code that is more complex than a single loop or a single if test should be compiled into its own object file (starting from its own cpp file), and the executable then depends on that object file as well as the one holding main(). … |
| | Re: Where to put \n [CODE]def wordReverseToLines(word): for i in range(len(word)-1,-1,-1): print (word[i]) # or def wordReverseUsingList(word): arr = [x for x in word] arr.reverse() print ("\n".join(arr))[/CODE] |

| | <sarcasm>I suggest Visual Basic since it is less general, only runs on Microsoft platforms, and is considerably less cutting edge than PHP.</sarcasm> |
| | Re: FTP Script First: Please us the (CODE) button when you post. It is good in lots of ways, and a requirement when you post code at DaniWeb. Second: You seem to be trying to build a baby source / revision control or backup system. Why reinvent this functionality when there are many … |
| | It is sometimes better to make things a [B]little bit[/B] more complex than they need to be right now if you can foresee the possibility of needing that complexity. In particular, moving toward a normal form is often worth doing to avoid having to stop everything while you rebuild a … |
| | Re: Need ideas! Uncommon? Use the Lego robot system to deliver messages among faculty. How about using a computer program to randomly assign students to seats in their classes, and see if changing the seating changes grades. |
| | C and C++ are more difficult languages to start with, though very powerful/fast-running and certainly not impossible. Free if you use the various Gnu compilers. Much documentation. Since you are just starting, I recommend that you try something with a smaller entry cost. Python would be good since it is … |

| | The real question is "Why do you want a million numbers in your excel file?" Excel probably can cope, but as long as you are handling the file now, why not do some work on the information [B]before[/B] you write it back out? You can use (g)awk to do really …  |

| | Suggestion zero: When you submit code, put [CODE] and [/[I][/I]CODE] tags around it. This gives line numbers and syntax highlighting in the display; and keeps your indentation: All good things. Also, when you post to DaniWeb, you agree to follow the DaniWeb rules, one of which is to use [CODE] … |

| | What is the result you want? Is it a library? executable? Something else? Whatever it is, you put that on the left of the colon, a list of the required prerequisite "things" (object files, libraries etc) on the right, and how to put them together to make your result on … |
