Wipe free space on Mac with CCleaner

The well known Piriform’s  PC Optimization software CCleaner it is now available on Mac for Leopard, Snow Leopard and Lion. It this post I will show You how to use “Wipe Free Space” feature of CCleaner.

But why should I wipe the free space on a hard disk?

When you create any sort of file in your system, what happens here is that there is actually a certain  hard drive space that is assigned to that file. That memory space is unique to that particular file. Now, when you delete that file, it would then be transferred to the Trash. When you empty your Trash, you then get rid of the file effectively, right? Wrong.

The hard drive space that was once assigned to the deleted file remains in existence. As long as this still exists,  can be virtually recovered by skilled technicians or hackers. This is one of the principles of data recovery software. So if You want that an information sent to Trash to be effectively removed forever, you need to use a wipe free space software.

CCleaner it is able currently to do 3 types of wiping: Zero Out, 7-pass erase and 35-pass erase. Any of those methods will generally make impossible recovery using commercial grade software recovery. The number of erasing passes it is relevant just for very sensitive data that could be hardware recovered by specialized laboratories in an controlled environment using direct plate reading even from defective hard drivers. But in this case it is better to use dedicated erasing software that include DoD and other sophisticated algorithms.

From http://www.piriform.com/ccleaner you can download CCleaner for Mac.

You can install like any usual application, with a simple drag to application folder.

In the tools tab You will find the Erase Free Space button as you can see in this screenshot.

You can choose the hard drive volume of which you want to wipe the free space. After that you simply press the Erase Free Space button. Depends on the size of the disk, could run for few minutes or for hours.

Free Online Photo and Image Editor – IMAGEBOT

www.tipit.infoWe are often use online editors, like webmail as an email editor, Google Docs as Office suite replacement for simple Word and Excel documents. Even photo manipulation web tools are popular. Recently I found out that the first free vector art library OpenClipart is using a online web editor to edit their .svg files. Even was ignored by major vendors like Adobe and Corel, .svg format is popular to InkScape users.

This logo was generated using imagebot editor from http://www.flamingtext.com  http://www.flamingtext.com/imagebot/editor

The tool is pretty simple to use. You can easily and fast create banners or buttons. You can work with layers, basic shapes and some effects. You can also save the work as png, pdf, svg, or jpg.

I will recommend for web use or for print just for small formats. That is because the effects are rasterized as bitmap no matter if you save as pdf or svg. So it is not a true vector editor, but very useful for quick projects.

Speed up file tranfer between MAC OS X and Linux Samba Server

After scratching my head few weeks, tweaking a lot smb.conf on my linux box, I found a Finder workaround, based on turning off display of server in sidebar.

Symptom: Slow file transfer over the network, between a MAC OS X Lion machine and a Linux machine (archlinux, currnet version). Also slow transfer between MAC and a PC based file server. How slow, let say finder reports about 1 hour for a CD size .iso file.

How to do it:

  1. Open Finder Preferences
  2. On Sidebar tab, disable Connected Servers
  3. On General tab, check Connected Servers

As a result, the mounted volume will appear on the desktop instead of sidebar.

In my case, this Finder workaround helped me to increase the speed more than 20x.

Please let me know if this has improved the share browsing and the file transfer speed in your case.Thanks.


In more than 5 years of existence, this website was constantly upgraded as back-end software (WordPress) and as a content. Subsequently updates of WordPress engine left some bugs in the admin area over the time. Even after I erased full website, except the content and database, I was unable to make it work properly the visual editor.

Given that 70% of posts are in Romanian and most of them obsolete, I do not want to have headaches with restoring backup and cleaning obsolete posts.

I will try in the future to re post the most interesting ones from archive.

You can have as a reference the archive.org webpage:


Here You can find snapshots of the past 5 years.

Because I’m not living anymore in Romania, 99% of the content will be published in English or French.

The mission of this website will be the same: to share the knowledge in a simple way: offering tips, tricks and how-to.

Almost all recipes are personally tested, but this is not a guarantee that will work in Your particular case.


I recovered 90% of the old website.
