CarlRevell / toString(base).js

Last active January 1, 2016 18:19

Don't forget JavaScript will return strings converted to a given base from a number...

	parseInt(64).toString(); // "64"
	parseInt(64).toString(10); // "64"
	parseInt(64).toString(2); // "1000000"
	parseInt(64).toString(8); // "100"
	parseInt(64).toString(16); // "40"

CarlRevell / ie6-and-ie7-one-character-hacks

Created December 30, 2013 15:14

Old but sometimes useful single character CSS hacks for targeting IE6 and IE7, typically when testing some bugfix for these old browsers.

	#myelement {
	color: #999; /* shows in all browsers */
	color: #999; / notice the * before the property - shows in IE7 and below */
	_color: #999; /* notice the _ before the property - shows in IE6 and below */
	}

CarlRevell / git-snippets

Last active January 1, 2016 18:19

Useful Git commands I've used and forgotten...

	# shows changes required to get from master branch to recyclingMicrosite; effectively what’s in recyclingMicrosite that’s NOT in master.
	git diff --name-status master..recyclingMicrosite


	# The triple-dot syntax ... shows what is in either master OR recyclingMicrosite but not both
	# typically these are commits since recyclingMicrosite was branched from master.
	git diff --name-status master...recyclingMicrosite


	# remove the recyclingMicrosite branch from the repo

CarlRevell / MySQL-log-to-table

Created December 30, 2013 15:45

Turn on SQL statement logging in MySQL to a table mysql.general_log

	SET GLOBAL log_output = 'TABLE';
	SET GLOBAL general_log = 'ON';

CarlRevell / MySQL-log-to-file

Created December 30, 2013 15:46

Turn on SQL statement logging in MySQL to the file /path/to/your/logfile.log

	SET GLOBAL log_output = "FILE"; --which may be set by default, I think.
	SET GLOBAL general_log_file = "/path/to/your/logfile.log"
	SET GLOBAL general_log = 'ON';

CarlRevell / Microsoft-Word-reverse-page-numbering

Created December 30, 2013 15:49

Using a combination of Ctrl-F9 (to insert field codes), F9 (to show field codes) and Alt-F9 (not sure) I inserted the following formula into the document footer to display reverse page numbers.

{= {NUMPAGES} - {PAGE} + 1}

CarlRevell / cacheBusterMinutes.js

Created December 30, 2013 15:52

Returns the same cache buster value for a given number of minutes. I use it by appending '&cb=' + cacheBusterMinutes(5) for example to ensure the same URL is used for 5 minutes and then changes after 5 minutes with a different &cb querystring value.

	function cacheBusterMinutes(cache_for_minutes) {
	var d = new Date;
	return d.getFullYear() + ("0" + d.getMonth()).slice(-2) + ("0" + d.getDate()).slice(-2) + ("0" + d.getHours()).slice(-2) + ("0" + parseInt(d.getMinutes() / cache_for_minutes)).slice(-2);
	}

CarlRevell / styling-based-on-number-of-elements.css

Created December 30, 2013 15:56

Neat CSS trick styling child elements based on how many of them there are... I used this concept on a contacts page to increase line-height when there were only three contact details (name, title and tel) and reduce line-height when there were four details (name, title, tel and email) to maintain the same height for the contact block.

	/* one item */
	.employee span:first-child:nth-last-child(1) {
	width:100%;
	}

	/* two items */
	.employee span:first-child:nth-last-child(2)
	, span:first-child:nth-last-child(2) ~ span {
	width:50%;
	}
