The One Secret Trick To Becoming A Genius Programmer

Okay, the title of this post is a bit of a lie. There's no one secret trick to becoming a genius programmer - there are two, and they're more habits than tricks. Nevertheless, these kind of 'secret tricks' seem to resonate with people, so I went for this title anyway.

Every once in a while, a somewhat strange thing happens to me. I'll be helping somebody out on IRC - usually a beginner - answering a number of their questions in rapid succession, about a variety of topics. Then after a while, they call me a "genius" for being able to answer everything they're asking; either directly, or while talking about me to somebody else.

Now, I don't really agree with this "genius" characterization, and it can make me feel a bit awkward, but it shows that a lot of developers have a somewhat idealistic and nebulous notion of the "genius programmer" - the programmer that knows everything, who can do everything, who's never stumped by a problem, and of which ther

Ubuntu on Acer Aspire Switch

The problem

What's the problem with this tablet? Why can't I just insert the USB and mash F12 until it boots? The tablet is made to run Windows 8.1 and Windows 8.1 only. Because of the stupidity that is UEFI (specifically it's "Safe boot" feature) we can't just boot from any USB stick we want.

Also, because someone thought putting a 32-bit UEFI on a 64-bit system was a good idea.

NOTE: This guide focuses on installing Ubuntu alongside Windows. If you're trying to replace Windows, then I assume you know enough about Linux to know which parts to change.

What you are trying to do is called a sparse checkout, and that feature was added in git 1.7.0 (Feb. 2012). The steps to do a sparse clone are as follows:

git init <repo>
cd <repo>
git remote add -f origin <url>
This creates an empty repository with your remote. Then do:

git config core.sparsecheckout true
Now you need to define which files/folders you want to actually check out. This is done by listing them in .git/info/sparse-checkout, eg:

mk-pmb

# New repository
mkdir <repo> && cd <repo>
git init
git remote add –f <name> <url>
git config core.sparsecheckout true
echo some/dir/ >> .git/info/sparse-checkout
echo another/sub/tree >> .git/info/sparse-checkout
git pull <remote> <branch>

# Existing repository

A quick run down on iptables rules

What is it?

iptables is a cli frontend to netfilter, the Linux kernel firewall/nat implementation for OSI layer 3 and 4.

Okay, give me more details

• When you run "iptables", the actual file being executed is "xtables-multi". That is, because the file name "iptables" is symlinked to "xtables-multi".

"How do I get started with Node?" is a commonly heard question in #Node.js. This gist is an attempt to compile some of the answers to that question. It's a perpetual work-in-progress.

And if this list didn't quite answer your questions, I'm available for tutoring and code review! A donation is also welcome :)

Setting expectations

Before you get started learning about JavaScript and Node.js, there's one very important article you need to read: Teach Yourself Programming in Ten Years.

Understand that it's going to take time to learn Node.js, just like it would take time to learn any other specialized topic - and that you're not going to learn effectively just by reading things, or following tutorials or courses. Get out there and build things! Experience is by far the most important part
