Ubuntu 11 - Creating a LAMP sandbox to play with

Deploy an Ubuntu LAMP server on your old PC, plug it to your home network and start web developing. The following guidelines were tested on a Pentium III x86 CPU processor, Ubuntu 11 Desktop edition and Windows 7 as the complementary primary PC. This is not a detailed tutorial, it is a notepad of necessary software and Ubuntu 11 specific solutions.

Facebook Wall: Clear everything

Facebook Wall: Clear everything - Remove ALL Activity

I had a problem to solve, clear my entire Facebook wall. By "clear" I mean to delete everything, status updates, links, events, photos, videos and their comments. The Facebook GUI does not provide such a function. I had to delete my facebook account -which I didn’t want to- or delete every single wall post manually one by one.

I then remembered my novice Perl skills. I had spare time, therefore I booted my Debian, I wrote a Perl script and voila! My Facebook wall was reborn.

Use Photoshop 32bit with Lightroom

You want more RAM, therefore you have installed a 64bit OS.
In this case I am talking about Windows 7 64bit.

Adobe Photoshop comes in two versions, 32bit and 64bit. Both of them are being installed at once on your system. The 32bit version can utilize almost 2GB RAM for each session. The 64bit version can utilize almost all your RAM... But not all your necessary third party plugins have upgraded yet to 64bit.

Lightroom comes in two versions too. If you are on Windows 64bit, the Lightroom 64bit will be installed. The problem is that you still mainly use Photoshop 32bit (cause of the plugins) but Lightroom opens the Photoshop 64bit for further editing. It is a normal behaviour, the 64bit version is the default one, you are on a 64bit OS afterall.

Firefox 4 font rendering

The much anticipated Firefox is out in the wild waiting to be downloaded. The feature list is long and exciting. Lifehacker has a nice article about what’s new and awesome in Firefox 4.

One thing I didn’t like was the Opera-like menu button. Opera is a respectful and innovation leading browser, it doesn’t look good to replicate exactly the Opera’s menu button changing only the color. Anyway, I can live with that, I love Firefox, I use it everyday. But… there is another thing… that is really annoying, the font rendering. Yep hardware acceleration support (Direct2D and DirectWrite is only available on Windows 7 and Windows Vista SP2) made the fonts blurry that in some cases causes astigmatism.

Thoughts on justified text

I had to come into a conclusion about fully justified text. I noticed that notaries in Greece (an observation from when I was a kid) always use justification, even in the old days of DOS text editors and monospaced fonts (ugly). I think it’s an old rule started from the manuscript writers. It is also correlated to formality. I, myself, instinctively still correlate "justified text" to formal text and I used justify alignment a lot.

Well I changed my mind a bit. Why bother about a sense of formality when text is not pleasant to the reading eye. I am not talking about unjustified - Left-Aligned (Ragged Right) VS justified. Every choice has advantages and disadvantages.

Mobile Codes

the qr code of this article

At the footer you can see the “Mobile Me!” block. It has a barcode image. It is a special barcode, a mobile code.

What are mobile codes?

“Mobile codes” are codes in the same way as ordinary barcodes are, but their matrix structure can hold more information. The codes are also mobile in the sense that you can use the camera on your mobile device to scan and decode them.

Read that info later and sync your browsers

If you have more than one computer or a smartphone, you found/will find yourself at least once into the situation bellow:

“You found something interesting in the web. You do not have the time to read it now. Whether you want to bookmark it or just keep it in mind to read it later, you have another problem to solve. Where are you going to read it later, on your notebook at home, on your smartphone or on any other of your computer/internet devices? The time factor (when are going to read it) may also indicate the computer/device you will use. What is the easiest way to note it down and read that note on any of your computers?”

Firefox profiles tip!

I like Firefox. Not because it is the fastest or it has the smallest memory footprint. I like it because I like it...

Ok, I have other reasons too. One main reason is its customization abilities. It can be a simple whitespace with an address bar or a web developer’s toolkit or everything you can build with the thousands of Firefox plug-ins (now called add-ons – extensions)

My daily/casual internet browsing requirements differ from the web developing ones and one thing for sure is that I hate bloated software. Too many extensions installed equals to “bloated” for me.
