The Saguaro Astronomy Club (SAC) Database is the result of more than 20 years of devotion to create and maintain a list of more than 10,000 worthwile deep-sky objects within reach of many amateur astronomers. The database is managed by Steve Coe and has a historic data format. It contains lots of information about these objects, such as the object type, celestial coordinates (RA and Dec), brightness, position angle etc. but also links to charts in the first release of Uranometria 2000.0 and in the Tirion Sky Atlas 2000.0.
This weekend my parents bought a new Acer desktop that comes preloaded with Windows Vista. Upon first boot you have to choose the OS language. Usually from then on the setup works flawlessly. This time it didn't.
Some Vista users are caught forever in a reboot lock after undoing an OS update. In this case you can either be happy to have a Vista recovery DVDs at hand (which we obviously didn't have), or the only remaining option is a partition editor.
Lunar eclipses are beautiful events where you expect to see a full moon but instead you see Luna obscured while it crosses Earth's shadow. On August 16, 2008 there was a partial lunar eclipse, 15 days after August 2nd's solar eclipse.
Two things connect both eclipses. First it's common to have solar and lunar eclipses around the same time. Second, both events were challenging to observe due to high altitude clouds in Brussels.
Opening up a public website to allow people to comment is a risky endeavor nowadays. Vandalism and ‘blog spam’ can be very labor intensive to cure after an attack. Fortunately there are a couple products and services that help in fighting this Digital Evil through machine parsing.
Today I have been introduced to the magical world of Twitter, some sort of ‘nanoblog’ where you can post what you're currently doing, but not much more. Yeah right you'd think, since Facebook offers this function as well for quite some time already. Granted, but Twitter allows you to do so very simply through the Web or even via your cell phone.
Read this first!
You have been warned. Now read on :-)
If you own a Mio C620 GPS you may have noticed that you can not add POIs (points of interest) out of the box, unless you key in the details directly on your GPS unit. Since I wanted to add about 60 gas stations this was not an option. Hence I have been searching for a way to upload my list of gas stations to the Mio C620 GPS unit. And add a custom icon for these new POIs.
Bored of spam (unsolicited mails)? I bet it's hard to find someone who is not at least annoyed by this intrusive phenomenon. For a couple weeks I noticed many spammers switched tactics from misspelling words in the subject to plainly insulting the addressee. It appears spammers constantly learn from online experiences to trigger your reaction. I wasn't expecting flame war tactics to emerge in the spam plague.
I decided to create a Tech Tips section to my site. Enjoy!
One of Drupal's key success factors certainly is its huge collection of modules. However, the sheer number of developed modules does not ease your search for extra functionality. In addition, sometimes the same functionality is provided by more than one module. Probably you'll like DrupalModules.com: on this site you can conveniently search for modules, restrict your search to a specific Drupal major release, choose between similar modules based on reviews...
Although many hosting providers now offer hosting packages with PHP and MySQL, most do not offer cron functionality, i.e. the possibility to schedule tasks. The simplest way to set up these scheduled tasks within Drupal is by means of the Poor Man's cron Drupal module. Once installed it will check whether cron must be run whenever your Drupal site is visited.
