Limit the # of rows being housed in a SQL table
This is a table design issue. I have a table that stores IP addresses. The data in the table is queried very heavily. The IPs can have different flags such as "unblocked", "temporarily blocked" and "permanently blocked". 95% - 99% of the IP addresses do not have any type of block on them. Is there a way to limit the # of rows in t...

Flexible numeric string parsing in Python
Are there any Python libraries that help parse and validate numeric strings beyond what is supported by the built-in float() function? For example, in addition to simple numbers (1234.56) and scientific notation (3.2e15), I would like to be able to parse formats like: Numbers with commas: 2,147,483,647 Named large numbers: 5.5 billion ...
Get factors of a number
I need to get two factors ( x, y ) of a given number ( n ) such that: x * y <= n x * y should be as close to n as possible x and y should be as close to each other as possible. Examples: n = 16 => x = 4, y = 4 n = 17 => x = 4, y = 4 n = 18 => x = 6, y = 3 n = 20 => x = 5, y = 4 Any language will do but preferably php. EDIT -- CL...

Finding the first number in a string using .NET 3.5
I have a bunch of strings I need to extract numbers from. They're in the format: XXXX001 XXXXXXX004 XX0234X There's a lot of these, and i need to loop over them all and extract all the numbers. So what's the quickest/most efficient way, using ASP.NET 3.5, to find the first instance of a number within a string? Update I should've inc...
Algorithm for assigning a unique series of bits for each user?
The problem seems simple at first: just assign an id and represent that in binary. The issue arises because the user is capable of changing as many 0 bits to a 1 bit. To clarify, the hash could go from 0011 to 0111 or 1111 but never 1010. Each bit has an equal chance of being changed and is independent of other changes. What would you...
MATLAB generate random numbers
Hi I am trying to generate random numbers in MATLAB with a random MEAN value. For example, if I use e = mean(rand(1000,1)) the answer for e will always be close to 0.5. What I want is for the value of e (mean) to be random, so that e can be 0.1, 0.2, 0.3, etc... Is it correct for me to use e = mean( unifrnd(0,1,[1000,1]) ) ? Thanks...
Ruby: "in `<=': comparison of Fixnum with Array failed (ArgumentError)"

However, a particular method is giving me the error mentioned in the title: def get_simps(num) curr = 2 print("Working...") while (curr <...
Trying to generate several digit intervals in one number (LUA)
Basically I have to use a random function that can return a number between 0 and 2^16-1. I am trying to make use of this and generate let's say, 6 intervals between 1 and 6 (thinking of dice poker). Basically use that one number that is randomly generated for me (I can specify range only) and preferably only have to call it once. Then t...
Can 12.1 be represented exactly as a floating point number?
This is in reference to the comments in this question: This code in Java produces 12.100000000000001 and this is using 64-bit doubles which can present 12.1 exactly. – Pyrolistical Is this true? I felt that since a floating point number is represented as a sum of powers of two, you cannot represent 12.1 exactly, no matter how many...
Regular expression where part of string must be number between 0-100
I need to validate serial numbers. For this we use regular expressions in C#, and a certain product, part of the serial number is the "seconds since midnight".
