Free your Mac memory for free


Mac OSX is beautiful, not only in its design, but also in its memory management. However, sometimes the inactive memory takes long time before released.

According to Apple support Inactive memory is

information in memory is not actively being used, but was recently used.

For example, if you’ve been using Mail and then quit it, the RAM that Mail was using is marked as Inactive memory. This Inactive memory is available for use by another application, just like Free memory.

However, if you open Mail before its Inactive memory is used by a different application, Mail will open quicker because its Inactive memory is converted to Active memory, instead of loading Mail from the slower hard disk.

In many cases you will need to jump from a heavy application into another, and then you will need either to accept the system performance, which is not deadly bad, or use a simple command line to free your memory.

First, how to monitor your memory?
Mac OS X comes with Activity Monitor Application that gives you a glimpse about your system resources, one major resource is your memory.
Read Apple help on Reading system memory usage in Activity Monitor

Now, how to free the inactive memory without having to reboot?

Open your terminal app and run
purge

Checking the ManPage of Purge, purge task defined as force disk cache to be purged (flushed and emptied) with a description Purge can be used to approximate initial boot conditions with a cold disk buffer cache for performance analysis. It does not affect anonymous memory that has been allocated through malloc, vm_allocate, etc.

No need to download an app to free your memory and moreover, you do not need to buy an app for that purpose, it comes for free.

Burn: Simple but advanced burning for Mac OS X


Burn Main Window (Image)

There are a lot of ways to approach burning discs. Burn keeps it simple, but still offers a lot of advanced options.

Keep your files safe and share them.

Burn your files to a disc so you can access them later on. Choose different filesystems so you can share your files with people with different operating systems.
Change advanced settings like, file permissions, the disc icon, file dates and more on the fly in Burns inspector.

Let the music be with you.

Create standard Audio-CD discs with ease. Just drop your audio files in Burns audio list. Want more music on your disc, Burn can create MP3 discs. More and more players support these discs. Higher quality, no problem, Burn can create DVD-Audio discs, which can contain more and higher quality files.
Burn offers advanced options like CD-Text and mp3 tag editing to personalize your disc.

Share your movies.

Made your own movies and want to share them with family and friends? No problem. Burn can create a wide range of video discs. From VideoCD to DVD-Video discs. And DivX discs to fit more of your videos on a disc.

To personalize your DVD-Video disc, burn can create interactive menus. Choose a theme in Burn or create your own.

1 + 1 makes 2.

Allready have discs you like to reproduce. Don’t worry, Burn can help you. Burn can copy discs or use disk images to recreate your discs. With one drive Burn still will be able to copy a disc, by temporary saving the disc.

Converting.

Forget worrying about conversion. Burn will take your video and audio files and turns them in the right format.
In the preferences you can set the options for quality and size.

Installing Android on iPhone 3G


So the verdict is out! You can’t get the most of iPhone OS 4.0 on your iPhone 3G but 3Gs and since I don’t have iPhone 3Gs nor can afford to buy it now or even interested in it anymore, I’m considering installing Android on my iPhone 3G.

None of the blogs I checked confirmed whether it can be usable, it seems to be experimental until now. So if anyone have experience in this, please let me know!

I miss this blog and I miss Ubuntu Community


I have been away from this blog for many reasons starting from personal decision to quit the professional programming life so I can go back to my real thing which is Politics ending with the lack of a better option; However I’m sure the years of programming life would have influence on my next step in life but not sure how yet.

I’m still interested in opening vim and coding but probably from now on it’s going to be for fun only; however I hope the theory that says if you code for fun you might end up making a profit more than you planned would work but yet I’m not going to spend lots of time on it as I decided to take a different path now.

The last straw was when I decided to resign from Dot.Jo (Which is an amazing company) to put more efforts on Ubuntu Community in the Kingdom and Arab world. Thankfully we succeed but partially due to the recession hit. It didn’t allow longer breath especially with the lack of sponsorship, we were so close to have National Open Source Office but I’d blame the recession and probably some other factors.

I’ve also decided to hand out access of communities I was handling like Jolug and specifically Ubuntu Arabic team, Ubuntu Jordan to some new blood; The good ones are taken seems to be true in communities case, all qualified people I approached were bloody busy to handle anything and right now Ubuntu Arabic and Ubuntu Jordan on idle mode.

As a amateur programmer from now on I might try to play with Django but not sure how it will go with the limited time for my hobbies but I will do my best to keep this blog updated at least with some general stuff but of course will try to stay away from iPhone VS android war; but don’t take it as a promise ;). I will also try contribute to Ubuntu Community, at least seasonally.

Until the next post.
