The Solvers Manifesto

http://www.solversmanifesto.com/

The Solver Manifesto shows our dilemma, as a web developer, probably not much to the backend developer, or system developer. But definitely web developer, which is a big chunk of software development jobs.

We are not engineer, we are not paid as much as an Expert, and we don't get respected like a artist. Yet, we hired because we knows how to program, yet we have to make things nice. And yet, our opinion is not respected. Even when technicians fixing stuff, nobody question how they do it. Not for us.

Random Python Learning : partial

On the holiday I decided to learn more on python, and really there is much to learn!!!!!!

One of the module I learn about is the functools module. 

One of the interesting function that I learn is partial, basically it is partial application of a function

for example

import functools

def adder(a,b,c):
    return a+b+c

def adder2(a,b):
    return a+b

add_three = functools.partial(adder,1,2)
add_one = functools.partial(adder2,1)

print add_three(1)
# would print 4

print add_four(3)
# would print 6

So you can wrap a existing without rewriting it, but give some default value to the existing function. And is actually used in python decorators.

Diff'ing and Patching

So I got like a few folders with different version source code, erm text files which I am comparing in my work. Either way, thanks to unix tools like diff and patch, things is some what easier. Though it is better to use version control, which I stupid enough not to

to compare files with diff, it is just a matter of

diff original new

then my team is creating the file on windows, which have \r\n, and me on linux, which \n. So to avoid this on diff

diff -w original new

this should able to ignore difference in white space character such as \r\n, which may not be a wise choice for python, because of the indentation sensitivity, which I trust my team sane enough not to mix tab and space(yes, for non-python progammer you can all laugh)

Since I have a directory, so i would run

diff -rw original-folder new-folder

pipe it to less just for making it readable.

If i'm lucky, it is just adding stuff to the text file, i would generate a patch, for that file by

diff -u original new > original.patch

and applying it with

patch original < original.patch 

in the folder. which i should really use -p1 option in the patch command, but there is a few folder have the same name, so i just put it in that folder and run it without -p1

of course sometime thing is not as easy. so it is nice to use to see all the difference with highlighting. which here i use vimdiff. which i use

vimdiff original new

Then I realize that doing all the diff and patch can be a pain in the back. So, a better use the code with version control, what ever reason, or how rush it is.

Actually in the current project i am working on, this would be a real issue, the user will describe the wrong type of solution(they insist of doing it their way). And along the way, will change their mind.

Even when we describe how it would work, or they describe what it should work, when we build it, they might change their mind, because they only see it once it is done.
