Ryan Campbell, over at particletree.com has recently published an article entitled: The Hows and Whys of Degradable Ajax.
It makes for an interesting read.
At my day job we’ve been adopting degradable javascript DOM scripting for some time, so degradable AJAX seems obvious to me. It is also the case, however, that many sites don’t bother with degradable code resulting in unusable pages for the 10% of people out there that have JavaScript turned off. Which is nasty.
Make sure when you read the article you read the comments - Jeremy Keith as ever is a wealth of information and catchy new designations!
On this day, in 1936, the last surviving member of the Thylacine species, Benjamin, died alone in his cage at the Hobart Zoo, Tasmania.
Yet another victim of mankind…
Why did I make this a blog entry? I don’t know - these things just matter to me…
Yow. Just discovered the solution to a bug I’ve experienced many times in the past! To be honest, I’m not sure why I haven’t looked for a solution before.
Often, having created a $_SESSION variable in PHP and then redirecting using the header command, you’ll discover your session has somehow disappeared! This is because you’ve technically done a redirect before PHP has worked out you’ve finished with the session. Solution? Tell PHP you’re done with the session using the session_write_close() function like so:
// Set up your session
session_start();
// Write something to it
$_SESSION['myvar'] = 'dave';
// Tell PHP you're done writing to it
session_write_close();
// Redirect
header('Location: mypage.php');What a doddle!
Typefaces (or Fonts). The intermaweb is full of them; some nice, some not so nice. Faruk Ates has recently posted a blog entry about the differences between serif and sans-serif typefaces and their use on the web. However, the article has brought me to an interesting question:
ClearType or no ClearType?
Windows XP allows you to select a better form of on-screen font rendering called ClearType within it’s display properties. This basically makes on-screen fonts a lot prettier. However, this feature is only available in Windows XP and is therefore limited to a select audience. For this reason, should we, as designers, have it turned on? Surely this could result in illegible fonts on our work for some systems that we’re just not aware of!
Personally, I keep ClearType turned off - but only because I spent many years working on a horribly archaic Windows 2000 system and couldn’t get used to ClearType when I upgraded. However this means that, whilst I’m working, my fonts are rendered in a more common format - allowing me to better design for a wider audience.
So, what’s general consensus on this?
According to New Scientist, China are on track to send a satellite to the Moon. Apparently they’re going to map it in 3D and do general science-type surveyanceseses.
I wonder what will happen when their survey finds no trace of an American landing mission…
