Thanks for the heads up – fixed the decoding issue

Comment on encdec – BaseXX Encoding and Decoding in JavaScript by Rob

Thanks for you efforts. I’ve think there are a couple of bugs in the javascript.

Firstly -
“if (num) {encode = alphabet[num] + encode;}” in “encode” and
“decoded += multi * alphabet.indexOf(s[i]);” in “decode”

This way of handling a string index works in Chrome/Firefox/Safari, but not in MSIE (even v9) as far as I can tell.

A more universal alternative is probably:
“if (num) {encode = alphabet.charAt(num) + encode;}” in “encode” and
“decoded += multi * alphabet.indexOf(s.charAt(i));” in “decode”

The second bug is in the cache mechanism. For example:

var base58 = encdec(); // defaults to base58
console.log(base58.encode(255)); /* output = 5p */
console.log(base58.decode(’5p’)); /* output = 255 */
console.log(base58.decode(‘p5′)); /* output = 255 – should be 1338! */

This is because in “decode” the line that caches the current decoded variable
“cache[s] = decoded;” is working with a reversed version of the “s” parameter.

This can be corrected by having another variable which saves a copy of “s” before it’s reversed eg “t = s;”, then using “cache[t] = decoded;”

Cheers.

I used it in a custom module. So yes, you would typically replace the hook part of the function name with the name of the module e.g. in the foo module the function name would be views_query_alter(&$view, &$query)

Could you please ellaborate a little more on how to implement your solution? Should this function be in template.php or in a custom module? The hook part of the function name should be replaced? Thanks

Ian, thanks ever so much for the write-up. More importantly thank you for being there. It was good to finally meet you (in-real-life), glad you enjoyed the conference.

Comment on A Show Grid Bookmarklet for the Drupal ninesixty Theme by derhasi

Hi Ian,
thanks for the bookmarklet. Mentioned it in http://drupal.org/node/1175762 .

I worked out a smaller call using jquery:
javascript:(function() {jQuery('body').toggleClass('show-grid');})();
For the moment I only tested it in chrome …

Comment on That Yellow Highlight Colour in RGB and Hex by Jonathan

this is the best pastel yellow color there is, mixed with the matching red and green and you’ve got yourself a winner!

Comment on Detecting A Drupal Users First Login by Ian

Ah, good point – hadn’t thought of that. The site I used this on was set to log a user in straight away once they’d registered, hence the values being the same.

Nice! Someday I might actually be able to make sense of those one-liners

Comment on Base58 Encoding in Python by Steve Anderson

Here’s a version which is not necessarily easier to read (read “not easier to read”), but does some mapping and recursive shizzle.

def encode(num):
“”" Returns num in a base58-encoded string “”"
num = max(num, 0)
return “%s%s” % (encode(num / base_count), alphabet[num % base_count]) if num else ”

def decode(s):
“”" Decodes the base58-encoded string s into an integer “”"
return sum(map(lambda elem: base_count**elem[0] * alphabet.index(elem[1]), enumerate(s[::-1])))

It passes all your tests but I haven’t checked it on anything else!
