one-line tree in python

One-line Tree in Python

Using Python's built-in defaultdict we can easily define a tree data structure:

def tree(): return defaultdict(tree)

That's it!

GDB init file to print STL containers and data members
#
# STL GDB evaluators/views/utilities - 1.03
#
# The new GDB commands:
# are entirely non instrumental
# do not depend on any "inline"(s) - e.g. size(), [], etc
# are extremely tolerant to debugger settings
#
# This file should be "included" in .gdbinit as following:
# source stl-views.gdb or just paste it into your .gdbinit file

Searches a graph and yields all the minimum spanning trees in order of increasing cost. This could be used to solve minimum spanning trees with constraints by yielding trees until we reach the first one which satisfies a constraint. For example it could solve the degree constrained minimum spanning tree DCMST

Build your own private, encrypted, open-source Dropbox-esque sync folder

Prerequisites:

  • One or more clients running a UNIX-like OS. Examples are given for Ubuntu 12.04 LTS, although all software components are available for other platforms as well (e.g. OS X). YMMV
  • A cheap Ubuntu 12.04 VPS with storage. I recommend Backupsy, they offer 250GB storage for $5/month. Ask Google for coupon codes.

Software components used:

  • Unison for file synchronization
  • EncFS for folder encryption

Better local require() paths for Node.js

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.

Possible solutions

Upcoming Features in C#

Mads Torgersen, MSFT

This document describes the C# language features currently featured in the March CTP. There's also discussion of a few of the VB features in the preview, where those are intended to be eventually implemented in C# as well.

Note that we have more language features planned that are not yet implemented. So look out for more to come in future CTPs and eventually a shipping version of C#.

This is my technical interview cheat sheet. Feel free to fork it or do whatever you want with it. PLEASE let me know if there are any errors or if anything crucial is missing. I will add more links soon.

ANNOUNCEMENT

I have moved this over to the Tech Interview Cheat Sheet Repo and has been expanded and even has code challenges you can run and practice against!
