Glorious RIM
The Playbook has its good points, but this snafu with its Music player is even present after the OS 2.0 update, that arrived in February 2012.

Here are a few advertisements for good books on computing, the best utilities people, and, would you believe it, but Microsoft software is not the worst material to work with. You wouldn't be using computers were it not for the arrival of the Windows 3.0 (admittedly inadequate) Operating System, that enabled home computing to take off.

DHCP insecurity, and a discussion that will never end: Windows v Mac!! Note that this page has been edited for legibility and spelling. The links on the page will lead you to the source of the argument.

And A Few Magazines
Byte (which needs a subscription) and typical pages from Jerry Pournelle and another that mentions creeping loss of security. Direct link: Jerry Pournelle (ex-Byte, always at Chaos Manor).  The email pages on his home site contain many themes, politics especially and are not always about computing, as is clear from my criticism of one of the polemics that was posted.
Dr Dobb's Journal and a recent, important editorial, referring to corruption and lobbying
Linux Journal
Windows .NET Magazine the name may change, yet again, but the contents maintain their excellence.  It's now called Windows ITPro whatever.

Publishers, Instructors, Training, Courseware
Mark Minasi NT/Win2k/Linux author/guru/speaker & Senior Contributing Editor, Windows .NET or IT Pro or whatever Magazine

Daniel Petri site: has given me lots of excellent information. Good forums, too.

Warriors of the Net, the visual Internet cartoon.
Donald Knuth (Programming Arch Wizard: author of the "Art of Computer Programming" vols I-III published; awaiting IV-VI+, although I doubt that he'll ever complete his masterpiece)

John Dvorak for maximum tech links.

Utilities?

Visit SysInternals and the Winternals co-site if they are still working. Bought by Microsoft in July 2006. Mark Russinovich and Bryce Cogswell who thought up and made work all of the stuff that IT guys use, have now become Microsoft employees. I hope that they are placed at a high level and can improve the quality of MS software.

Dvorak keyboard layout at M W Brooks and here is a pdf of same. This is Microsoft's page, and here too are Dvorak drivers to download. Since I use an International keyboard layout, which enables typing of accents, umlauts, etc., I prefer to use keyboards with Dvorak keys installed. Most have an option to change back to Qwerty should you need to do so: sometimes necessary for certain OSs. Above is the two-handed Dvorak layout.

Here is a page that explains the inertia in the US about reversing the idiocy of using a keyboard layout (Qwerty) that was designed to slow the typist. There are examples revealing the relative efficiency of using a DSK.

This yellow object is an image from the middle of the last century: an old conversion factors list. In my mind it is really neat, simply to show what units were used prior to the implementation of the SI system. To retain accuracy of the image, it is easier to download and then view it, especially if your browser resizes images. The other two clickable images to its right are from HMSO, printed in 1945; interesting how we had to use tables of logarithms and antilogarithms and such. I have my father's Five-Figure Logarithmic and Other Tables, by Castle, printed by Macmillan in 1934: it's somewhat tatty, but it's valuable to me.

Boswell's Q&A: Subnetting. An email that you can receive from MCP sources.
And this is the OSI in diagrammatical form. How any network is run, in theory:


 

Kingston Memory, which is highly recommended by Jerry Pournelle, among others. As is Crucial. Whenever you feel extra memory is needed, and it's not between your ears. For example, go to either site and search for this type of RAM: PC2100 CL2.5 ECC DDR SDRAM DIMM. Be very careful not to mix modules in slot pairings. Disaster will strike.
