What does your print statement look like?

Question: Does anyone have any recommendations that are likely to keep a large database healthy/speedy? I'm designing a database that is going to retrieve around thirty million data points a year, up to around three hundred million to a billion in a few years time when all of the sensors …

From my understanding MySQL locks a unit upon writing to ensure no reads happen during that: so writing blocks any reading you do. Depending on the storage engine you use ([more on that here](http://dev.mysql.com/doc/refman/5.1/en/storage-engines.html)) it may only block a row; or the entire table; you should probably choose to do …

Try [JUG](http://sourceforge.net/projects/jug/) that seems to be the one that works best for me; most of them out there seem unmaintained though.

You might be able to use the Google Charts API... https://developers.google.com/chart/ Other than that you could home-roll something with JQuery and/or HTML5 canvas elements. I'm sure there are a few people sitting around that would love to help as something like this is definitely needed out there (myself included)

How are you storing the images in the database? If they are just under the subdir, this should work, but if they are something like Base64, you'll need to use the data: uri format. Try doing a source view on your page to see exactly what is being output by …

A double takes up 64bits in memory (usually) you can find the specifics for your machine by using the sizeof() operator in C++. A float takes 32bits, again usually. Where an unsigned char has 8, meaning 256 values. If your round was above 255, it would cause your overflow. I …

[CODE] public class RectangleDemo { private class Rectangle { private double height; private double width; private String color; public Rectangle(double wid, double high){ height = high; width = wid; } public Rectangle(){ height = 1; width = 1; color = "White"; } public void setHeight(double high){ height = high; } …

Could you try giving us a little more information on the exact problem you're getting?

In order to get things working, you're probably going to have to find a way to hook in to the kernel on all operating systems in order for it to believe you have an actual ramdisk device. (In UNIX stle systems, you may be able to just connect to a …

Its unlikely you'll really need to worry about file size when you're dealig with a small dictionary, as you can get about 250 printed pages in a single MB of text, so a small dictionary shouldn't be a huge problem. That being said, if you really want it to load …

Are you looking for databases that have been attacked? If so, you should get some attacks pretty quickly by just putting one up... Other than that, you might be able to get some information at [url]http://isc.sans.edu[/url], they're pretty friendly towards researchers over there. - Joe

Hey, hope you still need this; I love seeing security stuff around: Joseph L. (if you need anything else and you can message me) 1. How important do you consider computer security? I am actually a security enthusiast, so information security is incredibly important, especially with so many institutions operating …

I think you're looking for something like this: [CODE] def mathFunction(x): return (x-1)*(x-3)*(x-5)*(x-7) for x in range(0,8): print x, mathFunction(x) [/CODE] Ranges take in up to 3 arguments, start, stop, and step: i.e. range(3) returns 0,1,2 range(0,10) returns 0,1,2,3,4,5,6,7,8,9 range(0,10,2) returns 0,2,4,6,8 There were two things problematic with your math …

[URL="http://docs.python.org/howto/regex.html"]Regular expressions[/URL] are probably your best bet being that you can't use a config parser.

This is probably not possible using conventional assembly, being that any kernel will stop your software from just randomly reading files as a security feature. You might be able to achive it through kernel calls though (check your man pages) or this manual: [URL="http://www.draga.com/~jwise/mach/documentation/essentials/manual/manual.pdf"]http://www.draga.com/~jwise/mach/documentation/essentials/manual/manual.pdf[/URL] Here is a book on assembly: …

Do you have a library that you're supposed to be using for the drawing? If not, you might want to look in to tk. [CODE]#!/usr/bin/env python from Tkinter import * tk = Tk() tk.wm_geometry("400x400") canvas = Canvas(tk, width=400, height=400) canvas.pack() canvas.create_line(0,0,400,400) canvas.create_line(400,0,0,400) tk.mainloop() [/CODE]

You could look in to building some kind of new NoSQL implementation, or something highly scalable on such a system (think perhaps a p2p dns system), they are all the rage these days.

I'd probably use something like Twisted if you can afford the size (it is kind of large). If things are on one network, you could just use a multicast packet to update all clients, that would probably be the cheapest assuming your router will handle it. Other than that, you …

It looks like f_path may be referencing the absoloute path to your images, rather than the path from the web root, so when the browser requests them you're getting the original absoloute path plus the web root, causing the images not to be found.

A bump might help here too. You might want to check out audiooop in Python: [url]http://docs.python.org/library/audioop.html[/url] Other than that, you might be able to check out how it is done in some of the free speech recognition softwares, like sphinx. - Joe

If you're in to math at all, I think Matplotlib is looking in to getting themselves working on Python3.

Just a guess: you might want to try escaping the dashes in your original date (use %2D instead of -) Hope it helps, - Joe

The problem with your first code (using socket) is that the actual section doing the writing isn't doing any output as that part isn't in the while loop: [CODE] import socket host = '' port = 8080 c = socket.socket(socket.AF_INET, socket.SOCK_STREAM) c.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) c.bind((host, port)) c.listen(1) while 1: csock, …

I've got some terminal session log files that I'd like to record in a video file, anyone know a good way to do this? Preferably it would be scriptable and not need X to be running so the server could do it automatically to these logs as they arrived. The …

It appears that you are using the same name for each textbox, typeTech? If so, only the last one on the page will be POSTed, try giving them different names, like 'deeptissue' then the POST value will be true or false, and you can test echo after a bunch of …

Python doesn't use a preprocessor, so you'll have to keep some kind of list to see what is defined in the current context, i.e. insert "BUG_XF_STALL" in to it when it is defined. Essentially, you'll need to write your own preprocessor. Then later on in your code you can use …

This site looks hand coded to me (from the weird looks of the source), so a good old text editor is all you need. You might be able to find some templates on-line though for free like at [URL="http://www.oswd.org/"]Open Source Web Design[/URL]. Flash would work, but remember that it won't …

If you provide the code you have for making the stick figure and buttons we should be able to figure out the best way for your program, otherwise we don't know what toolkit you're using (Tk, GTK, QT, WX, some derivative of pyGame). Perhaps you could hook an event to …

If you're in to games, you might want to try making Lingo, someone posted a problem they had in class about making the game and it looked fun enough that I might even try it (though I'm quite partial to the game). If you are looking to do something more …
