EC2 instance types's exact network performance?
...10%
*.8xlarge and marked specialty = 10 Gbit, expect ~8.5 GBit/s, requires enhanced networking & VPC for full throughput
m1 small, medium, and large instances tend to perform higher than expected. c1.medium is another freak, at 800 MBit/s.
I gathered this by combing dozens of sources doing b...
image processing to improve tesseract OCR accuracy
...e>mode>grayscale
image>scale image>1191x2000 pixels
filters>enhance>unsharp mask with values of radius = 6.8, amount = 2.69, threshold = 0
I then saved as a new jpg at 100% quality.
Tesseract then was able to extract all the text into a .txt file
Gimp is your friend.

What is the common header format of Python files?
...er to interpret the file using the given encoding. Most
notably this enhances the interpretation of Unicode literals in
the source code and makes it possible to write Unicode literals
using e.g. UTF-8 directly in an Unicode aware editor.
Problem
In Python 2.1, Unicode lit...
Finding all cycles in a directed graph
...er the starting point of multiple practical algorithms which apply various enhancements in order to improve performance and avoid cycle duplication. I was surprised to find out some time ago that these algorithms are not readily available in textbooks and on the web. So I did some research and imple...

A small enhancement in the answer which in practical may likely to use.

Git rebase: conflicts keep blocking progress

if you use Bash, enhance your bash prompt so it always presents this information automatically
One bit you mentioned I didn't understand: "and then try to carry on: at first i try a commit:"... why commit? In the middle of a rebase I think y...
When should we use intern method of String on String literals
...d to be interned. Apart from the leaner syntax, this is also a performance enhancement. But as others have pointed out, doing this harbors a great risk of introducing programming errors, so this should be done only as a desparate measure of last resort.
The downside is that interning a String takes...

Interface vs Base class
...nto a
rigid hierarchy.
Interfaces enable safe, powerful functionality enhancements via the
wrap- per class idiom. If you use
abstract classes to define types, you
leave the programmer who wants to add
functionality with no alternative but
to use inheritance.
Moreover, you can...
