The Razor for Lists of Regular Length

I’ve found that when reading how-to guides, philosophy, hundreds of blog articles in one sitting, etc., the following rule of thumb is useful:

Lists of important points rarely come in groups of round numbers like 5, 10, 100, 101, 50, etc. Usually, important points come in groups of unusual size such as 6, 17, 14, 231, etc. If there is a round number of items in the list, the author is likely just trying to write something people will read rather than about something that he/she cares about and ordinarily hasn’t investigated the subject thoroughly nor put only important items on the list.

I’m not really sure who came up with this razor (it wasn’t me), but it is useful for reading everything from eHow articles to The Art of War (of which approximately 3/4 is worthless babble and propaganda, the exception being the part on the various types of terrain).

Well, I hope that someone finds this heuristic useful.  Until next time…

What Web Users Need to Know About SPDY

ReadWriteWeb recently published a brief overview of SPDY, a new protocol developed by Google that makes web browsing more efficient. It combines the two-channel (control and data) communications approach of the older but still widely used FTP protocol with the power of the newer HTTP protocol.

As of this time, Microsoft is the only major vendor that hasn’t put SPDY support into its web browser default installations.

Since SPDY is implemented behind the scenes using free browsers and web server plugins, getting SPDY to work on your end won’t require much effort unless you do low-level web programming. But if you use the latest Chrome or Firefox, SPDY will speed up your browsing experience and cause your computer to consume fewer resources.

Background on Streamripper

Streamripper is a free software utility that allows ripping audio files from Shoutcast streams, analogous to recording the radio on cassette tapes. If the underlying Shoutcast stream supports it, Streamripper can separate out individual tracks–dividing commercials, songs, talk segments, and other audio intervals into individual MP3 files. Making recordings of Internet radio is in something of a legal grey area, but it is on much firmer legal ground than downloading music using file-sharing software. As long as you don’t distribute the recordings to others, you should be OK.

You can download Streamripper from the official web site and you can find Shoutcast streams on Shoutcast.com, which currently boasts over 50,000 Internet radio stations. A Streamripper plugin is also available for the popular Winamp software. There is no better way to legally download music from the Internet without paying for it.

Stanford’s Free Open Classes for Spring 2012

Stanford University is building on a highly successful experiment carried out in Fall 2011: offering free online classes to the public.  While these classes carry no college credit, you will receive a letter of achievement (containing your score) for successfully completing one.  If you are thinking about signing up, keep in mind that taking any of these classes is quite similar to taking a traditional college class for credit in terms of the time and effort involved.  They aren’t easy, and it takes serious  dedication to get a 100% in any one of these courses.

Review of Mailinator

Mailinator is a great service that lets you set up disposable email addresses with absolutely no effort whatsoever. You simply have email sent to <your mailbox name>@mailinator.com, go to www.mailinator.com, enter your mailbox name, and presto! You can see your email. Be aware that there is no security on Mailinator mailboxes, so they aren’t extremely well-suited to exchanging private information like passwords, but if you need a disposable email address for the purposes of avoiding spam, Mailinator is a great tool.

Microsoft Office Online on Skydrive

Microsoft’s latest foray into cloud computing is called SkyDrive.  They are currently offering 25 GB of free storage that you can access from anywhere with an Internet connection.  They also have a web application suite known as Microsoft Office Online that allows editing  Microsoft Word, Excel, and PowerPoint files stored on SkyDrive in your web browser.

Some believe that as users increasingly rely on small, handheld devices–cell phones, PDAs, tablets, and eBook readers–for their daily needs, use of web application suites may greatly increase.  Whether or not that is correct, you can now take advantage of web application suites for your own needs.

Introduction to Artificial Intelligence – Fall 2011

Peter Norvig, Google’s director of research, is teaching Introduction to Artificial Intelligence at Stanford University this fall.  The class can be taken for credit by Stanford students and is also free to the public.  There are two tracks available for completing the class: 1. The basic track, which features classroom lectures and basic quizzes and 2. The advanced track, which is the full course, with homework assignments and tests.  Members of the public who take the class can receive a certificate of completion, and it is completely free.
