SEE, Programming Abstractions, Assignment 1

SEE, or, Stanford Engineering Everywhere, has turned out to be my favourite E-learning resource; I’ve dipped into it a few times over the past few years but in light of my recent investment into a CUDA enabled Graphics Card, I thought that it was coming high time to brush up on my C++ programming, which I’ve basically left stagnant for two years after advancing no further than function pointers, structures, and templates.

So, in the spirit of openness that SEE tries to foster, I’ll be blogging my work through their CS106B course, Programming Abstractions, the second of three programming courses. (I passed on CS106A, Programming Methodology, since I’ve had enough Java shoved down my throat to last a lifetime…).

Add a Twitter @anywhere hovercard to links containing tweeps

Everyone and their dog has a walkthrough of adding @anywhere hovercards to your blog. But the default has a small failing that irked me when I was re-doing my Blogroll (check them out, they’re all great! I promise!), and that was that if you take a tweep, like @god for example, it’ll happily wrap the hovercard around it, but if you have a link to this great status that @god posted, @anywhere won’t pick this @god up.

Shaded Headers in Thematic

So, as you can see the blog is sporting a new, cleaner look. Nothing better than experimenting! One of the nicer aspects of the new setup is the shaded headers (ie. <h1>/<h2> tags).

Facebook Group Library

I am sick and tired of seeing ‘so and so joined SOMETHING COOL EVERYONE SHOULD SEE‘ only to check out the group and see its behind a join-wall. so I’m starting my own library of pointless Facebook  joinwall groups along with alternate source material and a brief of what is behind the joinwall. Affectionately known as FGL. Check it out and let me know what groups you want exposed.

US confirm status as ACTA transparancy stopping block

“In this upcoming round of ACTA negotiations, the U.S. delegation will be working with other delegations to resolve some fundamental issues, such as the scope of the intellectual property rights that are the focus of this agreement.  Progress is necessary so that we can prepare to release a text that will provide meaningful information to the public and be a basis for productive dialogue.  We hope that enough progress is made in New Zealand in clearing brackets from the text so that participants can be in a position to reach a consensus on sharing a meaningful text with the public.”

Listing just dot-files

Its a problem that I’ve come across, and I’m not the only one, so heres what works for me to find those pesky files that start with a .
ls -a | egrep -i "^\."

This only works in the current working directory, which is the normal usage.

FYI the reason that this is problematic is that the ‘.’ symbol is a single character wildcard; most people are familiar with the asterisk ’*’ indicating ‘anything, however long’, whereas the ‘.’ means ‘any single character’.

The command works by looking only at the first character of the file (‘^’, thats called a caret) and then removing the special meaning of ‘.’ by escaping it with the slash.

Update:18/4/10
@stevebiscuit correctly pointed out that the -i flag is unnecessary.

-iinstructs egrep to ignore the case of any matches, so that ‘HeLlO’ matches if you egrep -i for ‘hello’. Since there is no case for the ‘.’ symbol, the -i is pointless.
