 | OK. masijade gives up, but I will take a swing at it: When you need something to be in your working environment "forever", then you do it by editing one of these two files: [ICODE]$HOME/.bash_profile[/ICODE] or [ICODE]$HOME/.bashrc[/ICODE] Use the first file if it exists, else the second. Use a text … |

| | Mm. So you unzipped the distribution, looked inside, found the installation instructions and followed each of the steps religiously? If that doesn't work, then perhaps use one of these wrapper distributions: or equivalent which are supposed to make installing a working system somewhat (or much) easier.

 | Re: Bootstrapping The story is that if you try to pull on your boots (which you do by holding the bootstraps and pulling upward), and the boots are a 'perfect fit' (very tight), then you might pull yourself up into the air by your bootstraps. Hence the name 'bootstrapping': A compiler that … |
| | I don't do MSSQL, but for other databases, it is perfectly ok to keep all the data in one (set of) table(s) and simply run the query for the most recent N rows (or for all the rows within a time range, or however you prefer), as long as there … |

 | my guess: You compiled to an executable that has the same name as an exe that displays a bouncing ball... and that existing exe is first on your path. Just a guess. |
| | I found the [URL="http://en.wikipedia.org/wiki/Boyer%E2%80%93Moore_string_search_algorithm"]wikipedia[/URL] article easy to understand. The main thing, for me, was to [I]get[/I] that the preprocessing allows the algorithm to skip forward by more than one character when there's a miss. |
| | Re: threading Yes, that is approximately the usual way to create Python threads. Why do you need locking? Best to be a bit more specific about your question. |
 | There is also the use of a scripting language to present the UI, trigger core routines written in C, C++, Prolog, FORTRAN, or whatever. Python has a quite accessible interface for doing that. The upsides to doing it this way: [LIST] [*]You can prototype entirely in the scripting language: Quick …  |

| | I don't know what you mean by 'subtracting lists'. With your[icode]listSum()[/icode]you implicitly start with the accumulator set to 0. What is the initial value of the accumulator for a subtraction? Or do you want to 'subtract' one list from another? As a set or each element from its matching element? …  |

| | Well for starters, lines 6 through 25 make me itchy. This is what I would do (assuming you really want a single dimension array of boxes)[CODE] bricks = [] for i in range(-5,6): bricks.append(box((i,9,0),1,1,'white',materials.marble)) for i in range(-4,5): bricks.append(box((i,8,0),1,1,'white',materials.marble)) [/CODE]That seems to answer your first question. On the other hand, … |
| | Re: A test for input First: Please use the (CODE) button when posting code. It does all good things, no bad things, AND it maintains indentation, which is critical for Python. Second: I would use a dictionary like this: items = { 'd': ("Dagger", 10), 's': ("Sword", 50), # and so forth } # and … |

I see several candidates: [LIST] [*]line 2: Why return void when you can return something useful (there may be a good reason, but a comment might help) [*]line 15: I think you want [icode]while(*itBegin < *pivot)[/icode] [*]line 17: You are not looking at the … |

| | If you don't need to keep track of the history of the changes, then if you merely UPDATE the row instead of adding a new row each time, your problem is solved. To keep a history, you can store a "running total" so that your "view" query only looks at … |

| | You really have no useful choice about wasting space for unanswered questions: You can have a lot of little tables, one for each question, each holds a foreign key: patient_history.id and the various answer fields; or you can have one wide table that has a lot of nullable answer columns. … |

For simple singly linked lists: [LIST=1] … |
 | I would have used a list of pairs, or maybe if there are a lot of options and looking up the hints is important, a dictionary, though that isn't the right thing here.

| | The issue is, I think, whether online gaming skills do actually translate into the work environment (and how well, and is the transfer useful). For instance, I can imagine some online leader whose persona is considerably rougher than I'd want a manager to have in a company where I worked. …  |
| | Yes, this does seem somewhat complex, but you can do it in steps. After each step, make sure your program continues to work as well as it can at that step. [LIST=1] [*]First, think about how this program interacts with the user. Write something that does the interaction, but none … |
| | That would work, as would pulling a significant chunk (1000?) bytes from the board and comparing its hash with the last hash. I'd do it in Python because I'm a Python kinda guy, but wget or cUrl would work well from the shell. |

| | There are three aspects you need to think about: The data that is stored, how to let people look at the data, and how to allow the data to change. This is traditionally called MVC: Model (data), View, and Controller. For the [B]model,[/B] a relational database is actually the easiest … |
| | First, a bit of historical information: [url]http://en.wikipedia.org/wiki/Thomas_Bowdler[/url] The word is actually [B][I]bowdlerize[/I][/B]. That's fun, but not important. Second, a list is indexed by an integer, not a key, so you want something like [CODE]for i in range(len(s)): ... s[i] ... # [B]not[/B] s[w][/CODE] Third, you will need to call your …  |
| | Good for posting code. Not so good for not using the (CODE) button. When you re-paste, highlight your code and press the button (or press first, then paste between the code-tags). You really need that for Python: Indentation counts, and that is how you get it; you also get line … |
| | You don't need to have a[ICODE]break[/ICODE]commend in the[ICODE]quitLoc[/ICODE]function. Just erase the two instances at lines 5 and 11 and all will be well: if/elif will enter only one of the blocks, then exit the function with a None return value Aside: All those globals are bad form... but I'm not … |

| | Ug. How did you manage to get rid of the line numbers and code coloring? Use the (CODE) button next time, please. There are a lot of problems, but lets start with just three: 1. What you show can't even be running: It would stop with a problem on the … |
| | Delete duplicate post. Sigh. |
| | Why use partition() instead of split()? What happens with 'malformed' lines such as [ICODE]word1\tword2[/ICODE]. Using split() would fix that problem (but cause the generator to store a lot of data if the lines are long). |
| | You got fooled by the instruction in the posting box. code-tag must be followed by code-tag, and similarly for icode and icode. That instruction fooled me too.
