Laptop Rescue Follow-up

This is a follow-up to my previous post (opens in new tab/window) about rescuing an old Windows laptop. Since publishing that article I’ve done a bit more work on the laptop to set it up for Skype. This article deals with setting up Skype sound settings for a USB microphone.

Laptop recycling

They always told me that it was possible to rescue old laptops too feeble by now to run Windows by installing Linux.  Despite being a Linux convert, I always took that with a fair bit of salt.  I was wrong.  Here’s the background.

Lisp development with GNU Emacs

Just out of interest I decided last week to revisit Lisp.  Usually I have no problem learning a new computer programming language, but when trying Lisp as part of an Open University post-graduate computing course about ten years ago, I didn’t really get on with it.  It wasn’t that I couldn’t do it.  I passed the module, after all, although not with a great mark.  It was more that I didn’t ‘get’ it.

Installing AdBlock in Firefox

I recently commented on a FaceBook entry complaining about some adverts in FaceBook.  My reply was to ask why the poster was seeing adverts at all.  In the subsequent discussion, it became clear that knowledge of AdBlock was not as widespread as I’d thought.

So here are some instructions for Firefox on Windows and Linux.

Photoshop CS2 under Linux

You can download and install PhotoShop CS2 on your Linux box.  This article explains how to do it.

Although I would always recommend using the GIMP for image manipulation on Linux (or on Windows or OS/X for that matter), some people seem wedded to PhotoShop – and those people might be your customers or college tutors or other people you can’t ignore.  So I’m going to swallow my principles and explain how to keep them happy.

Java Threads

Somebody asked me this week about Java threads.  In particular, they wanted to know how they were scheduled.

Now, before I go any further, I should state quite clearly that this is not my sphere of expertise; but I am perfectly capable of using Google and that being the case, the following is a summary of what I found.

Using TextPad for Java programming

A friend of mine recently started a Java programming class.  In the classes, they use Windows and TextPad, so my friend asked me if I could help him set up a similar environment on his Linux box (Ubuntu 12.04) under WINE.  Never being one to refuse to help a friend, I agreed.

The following instructions, though, apply just as well to Windows users.  Just ignore the references to WINE and issue the commands directly.  You may also find that you will not have to alter the Windows PATH variable, because it will be done for you during installation.  If you do have to alter it, though, don’t use regedit.  Do it the normal way, via My Computer or whatever Microsoft call it on your Windows version.

Another Windows 7 stupidity (or two)

For years I’ve had little or nothing to do with Windows and suddenly I find myself having to come to grips with it in order to teach others how to use it.

One of my users accidentally set the default program for .lnk files on her Acer Aspire One netbook to a specific program.  So then every desktop icon wanted to use Adobe Reader—as it happened—to open its associated executable.
