Compiling LaTeX on Windows: An alternative method 2007-07-22 20:12:00 The usual method
to compile latex is by using "latex" command, and if the latex file contains bibliography, it will be a very tedious and repetitive job.To produce a dvi file:latex yourfile.texbibtex yourfile.texlatex yourfile.texlatex yourfile.texTo produce a pdf file:pdflatex yourfile.texbibtex yourfile.texpdflatex yourfile.texpdflatex yourfile.texHowever, for the windows user, with miktex, there is an alternative that could simplify all those tasks - the texify.To produce a dvi filetexify yourfile.texTo produce a dvi file and clean all the auxilary filestexify -c yourfile.texTo produce a pdf file (to clean all the auxilary files, just add -c as above)texify -p yourfile.texTo produce a dvi file and run the default viewer (add -p for pdf)texify yourfile.tex --run-viewer

Python: Conditional Statement with lambda 2008-04-06 15:29:00 Let say that we have a conditional statement:In Python
, we can write it in three ways:>>> f = lambda x: x > 2 and (x + 1) or 0or>>> f = lambda x: 0 if x <= 2 else (x + 1)or>>> f = lambda x: [x + 1, 0][x<=2]However, if the number of conditions if more than 2, it is best to use the first method.For example, consider this conditional statement:The Python code is like below:>>> f = lambda x: (x>=5 and x+1) or ( (x < 5 and x > 2) and 3) or 0We read it as:if x >= 5, f(x) = x + 1else, if x > 2 and x

Add all the natural numbers below 1000 that are multiples of 3 or 5 2008-04-09 19:27:00 Problem #1 of Project EulerAdd all the natural numbers below 1000 that are multiples of 3 or 5.Analysis:Sequence of multiple of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, ..., 999Sequence of multiple of 5: 5, 10, 15, 20, 25, 30, ..., 995So, the sum is 3 + 5 + 6 + 9 + 10 + 12 + 15 + 18 + ... + 999Take note that we have to remove the duplicate of 15, 30, 45, ..., 990Method # 1: using PythonAll the natural numbers below 1000 that are multiples of 3 or 5, are divisible by either 3 or 5. Hence, we need to add the numbers that are only divisible by 3 or 5. That is very easy in Python. Using the % operator will give use the remainder of the division.For example, 4%2 = 0, 4%3 = 1.Therefore, in order to ad the number that is divisible by 3 or 5, we have to check for the remainder. We will only add the
