What lemonade can teach us: A value is defined by how much personal importance we attach. Attributeless things are worthless.

Found it via twitter and worth a read.

Since a few months I had the very strange issue that the default samplerate is 48KHz which caused me to set it manualy each time I wanted to play “normal” encoded audio. When I upgraded to windows 7 the control panel stopped displaying. It launches correctly when windows starts but it won’t open the control panel when i click it – and it’s strangely enough to mention that the pane preview works fine. Since I am listnen to music primary via winamp, I could work around the samplerate issue via the out_aiso plugin, so that I can listnen to music again.

However, the disappearing of the control panel “on screen” can be eventually solved if you do the following very few steps:

• close the control panel
• open up rededit
• navigate to HKEY_CURRENT_USER\Software\Creative Professional\E-MU USB Audio Control Panel
• delete the following entries: “WindowX”, “WindowY”
• launch the CP again and you will see it again

In this post I’ll show you the one and only correct way to use sprites and the very little benefit if you use sprites the wrong way.

It’s in everyones mouth but a lot of people do not understand fully what sprites are supposed to optimize. Well we want so badly to reduce the HTTP requests but as I’ll show you, a lot of people do not understand how to write efficient selectors for sprites.

Here’s a meaningfull chart I’m going to explain a few pixel down.

The first “wrong way” uses multiple images and no sprites and show you what you might except. For each image a request gets done. 22ms were used.

The second wrong way shows you something, a lot of people wouldn’t have guessed. For each CSS selector a request is made! The reason is, that the Browser does not know that the image has been already requested and requests it again. The browser then, when it does it’s pre-processing understands, that tghe ressource has been already requested and grabs it ideally from the browser-cache. However that’s just 4ms faster than without sprites.

.icon-mail 			{ background: transparent url(images/sprite.png) 0 0 no-repeat }
.icon-mail-add 		{ background: transparent url(images/sprite.png) 0 -40px no-repeat }
.icon-mail-attach 		{ background: transparent url(images/sprite.png) 0 -80px no-repeat }
.icon-mail-delete 		{ background: transparent url(images/sprite.png) 0 -120px no-repeat }
.icon-mail-edit 		{ background: transparent url(images/sprite.png) 0 -160px no-repeat }
.icon-mail-error 		{ background: transparent url(images/sprite.png) 0 -200px no-repeat }
.icon-mail-go 			{ background: transparent url(images/sprite.png) 0 -240px no-repeat }
.icon-mail-link 		{ background: transparent url(images/sprite.png) 0 -280px no-repeat }
.icon-nail-open 		{ background: transparent url(images/sprite.png) 0 -320px no-repeat }
.icon-mail-open-image 	{ background: transparent url(images/sprite.png) 0 -360px no-repeat }

The third and correct way uses one selector containing the sprite and a few others to change only the position of the sprite. As you can see in my fancy chart, the benefit is: 4ms for the whole test document. Thats 5.5 times faster than the first example and unbelievable 4 times faster than the second example, which uses the very same sprite!

.icons { background-image: url(images/sprite.png); background-repeat: none }
.icon-mail 			{ background-position: 0 0 }
.icon-mail-add 		{ background-position: 0 -40px }
.icon-mail-attach 		{ background-position: 0 -80px }
.icon-mail-delete 		{ background-position: 0 -120px }
.icon-mail-edit 		{ background-position: 0 -160px }
.icon-mail-error 		{ background-position: 0 -200px }
.icon-mail-go 			{ background-position: 0 -240px }
.icon-mail-link 		{ background-position: 0 -280px }
.icon-nail-open 		{ background-position: 0 -320px }
.icon-mail-open-image 	{ background-position: 0 -360px }

ps: You need something like firebug or httpwatch to check it for yourself.

Every once in a while I write something really personal – and today is such day. As I’ve posted earlier on my flicker account, my step dead died a lonesome death. A few weeks have passed and all I can say is that time moves pretty fast. Your Mom gives birth and it’s you – your parents raise you and especially when you’re young – time moves so slow – you can’t become old enougth to early. However – the older one become, the faster lifes moves. Not forgetting: the faster it goes on – the less we do remember certain things. Less we wonder and slowly we loose the ability to be surprised.

This post is personal – as I’ve already mentioned – and I guess I am in the position to say that I’ve matured without becoming old. And for my step dad – I’d arrogate to oneself that i knew him that much, that he was a good person suffered a great burden he was unable to fight. Over a few years he has supported me financially and personal – because as he stated – he was able to at that time. I know he had a good reputation and people liked him for his honesty and the ability to say whats important. The sadly part about it – he wasn’t able to do all the good things to himself – which he adviced to others. It’s always easy to give good advice …

And the good thing is – he’ll be in my heart – forever. No matter how fucked up the situations sometimes was with him … he tought me a few essential things I continue to teach aswell to others:

• have a real opinion
• believe in yourself
• it doesn’t matter what other people say – as long as you don’t betray yourself

In two weeks will be the ceremony and I guess it’s my first funeral after all … and the family will come together – after long period of being not together.

May he rest in peace and whatever he has wished for shall come true in eternity.
Word!

PS: A few links I’ve just discovered about him (in german):

• abendblatt about his death notice and obituary
• grüne wedel (scroll down to Bernd Reifhardt) about his political career
• abendblatt about his political retirement in 2002

try to run a cleanup and remove all obstructed files from your local copy. Or better said: copy them to a save place! Now remove all .svn dirs from your copy and run an update on your local project and copy back the »obstructed« dirs/files. Hit refresh and commit it. That should fix the “obstructed” files.

The reason might be, you’ve copied from another repos some files – including – some .svn dirs.

if you install apache/php and get the following error:
Warning: Unknown: failed to open stream: Permission denied in Unknown on line 0
Then consider to check the permissions.

What user/group has the apache?
ps -ef | grep apache

Who owns the files in your htdocs?

…

Because it is most likely that you need to chown your htdocs, and or add a user to the correct group.

At work we’ve ordered a new server and I’ve installed and configured apache, mysql, php5 and lighty + some tools, when spontaneously ‘less’ died and also ‘vim’ broke. Then mysql didn’t start, because ‘There’s not enough space in /var/lib/mysql/’ and the eth0 changes I made broke aswell. reinstalling mysql didn’t solve it – actually the installation broke. Dependencies errors and the same ol ‘not enough space’ stuff. ‘Dmesg’ is reporting ‘Invalid field in CDB’ a few times and that eth0: link is not ready…

This is a fresh server with 500gig and only 1% is in use – so there is space and I guess there is something else wrong. fsck ‘mention’ that the superblock is corrupted. Well ok – I know it is not so wise to run fsck on a running mashine – it would be more wise from lilo or a live cd – but it is a ‘managed OS’ so the hoster do not provide such thing. If the worse get worse, I can call them and let em reinstall everything but all my configurations would be lost – or at least I had to copy my configs to the new one.

Right now I am in fsck’s interactive mode and pushing the confirm button repeatedly and /lost+found is getting affiled.

And then some message:
/dev/sda1: 37458/30277632 Dateien (1.3% nicht zusammenhängend), 2216874/121093945 Blöcke
and the console stands still. no Ctrl+C, no ‘enter’, no nothing works…

*duck*

and then

… and even today: awesome!

bigger, better, faster. (AMD Athlon 64 X2 5600+ Dual Core / 4 GB DDR2 / 2 x 400 GB SATA II / Debian)
Well ok – bigger, and better than the current one

We woke up at 7am and I was tiered as fuck, because it was after 1am
when we finaly went to bed. I kinda hate it when I go on a trip – the
preperation sucks but luckily we’ve managed everything in time, at
least we didn’t miss the train. What can I say – the weather is and
was fine – the sun is shining and I try to be relaxed.

Of course we went to the ‘Semper opera’, the ‘Zwinger’, the
‘Frauenkirche’, took some tourist-like photos and spent the evening at
‘Neustadt’.

Right now we wait for the ship to ‘Rathen’ to see the ‘Elb-Sandstein
Mountains’ and I am starving and hope there something to eat on board.
A sausage with mustard + a bun would be great!
