"The problem the pattern attempts to solve: identify the URLs in an arbitrary string of text, where by “arbitrary” let’s agree we mean something unstructured such as an email message or a tweet."

"Oftentimes, you'll want to fit a line to a bunch of data points to make it easier to spot patterns or relationships. It might be observations over time or it might be two variables that are possibly related. In either case, a scatter plot just might not be enough to see anything useful. This tutorial will show you how to graph a fitted line, or loess curve, to such a scatter plot."

"Don’t you hate when you can’t remove that file full of cleartext passwords from your github account? Even if you git rm it, it still is accessible in previous versions of the tree. So, you need to rewrite the entire tree. Fortunately, this is really easy with git."

"If anyone is interested in chatting about what makes a fund a more "successful business" drop me a line. Getting more AUM (assets under management) is the goal of most funds. The maintenance fees of 2% are ridiculously high.

The magic threshold in the business is $100m AUM with +36 months of exposure because these are the operational levels, where most institutions start looking around at allocations. Please note instituional sales cycles for allocations are 9-12 months, while family offices are estimated at 12-18 months."

"In gift wrap emergencies when you've got the present but need some wrapping, here's an idea for turning a magazine page into a bow. (There may be better ways to stick this thing together, but I used what I had on hand: staples and adhesive glue dots)"

"Are you familiar with RSpec, new to Sinatra, and can’t get the two to cooperate? This article maybe of use to you. Alternatively, if you’re like me and you’re simply new to this universe all together, this article can certainly be of use."

"You know that excellent explanatory piece you produced four weeks ago as a sidebar to a big news story on your topic? Rescue it from the archives and put it in a nice, prominent place online. Link to it with a clear, compelling headline.

Pull together a page online with links to several such explanatory pieces (from your site and elsewhere), along with good, useful digests of all of them. Make it so that users don’t have to visit every link to get a picture of the story, but have places to go when they want to know more. Set a recurring reminder to check in on this page once a week. Create a shortened URL for this page and repeat it every time you cover this topic."

"RSpec, Cucumber, Webrat, RCov and Autotest are a powerful combination of tools for testing your Rails app. Unfortunately getting them to all work nicely together can be a bit of challenge. I recently configured a development environment from scratch on OS X 10.5 Leopard and kept track of all of the little details."

"These web pages are about a project I've been working on. Put briefly, it's a WWAN (Wireless Wide Area Network) router. In more human terms, it's a compact little box that gets data from cellular towers and re-shares it for multiple computers to use.

To use it all you do is plug it in to the cigarette lighter of a car (or a 12v supply when at home). It automatically boots up and links in to Verizon's "Broadband Access" service, turning itself into an access point. Turn on your laptop, join the network and voila -- you're on the net! It's just like using a hotspot (such as they have at Starbucks and airports), but it goes anywhere you car goes."

"Let's go through a specific example of setting up a Semantic Forms-based wiki from scratch. Let's say that you want to create a wiki that shows all the books you have at home. We'll then go through the steps specified in "Getting started"."
