SPAM is a primary reason to block comments, after allowing comments on the site I had to delete many spam comments daily from the approval queue, that forced me to enable captcha for comments to prevent or decrease comments from spam bots.

Now everyone can comment on my blog, I will review the comments before publishing them though to keep it clean here.

There may only be a few hundred thousand users running desktop Linux worldwide, compared with tens of millions of Mac users and hundreds of millions of Windows users, but almost all of us are using Linux on a daily basis.

In addition to the article examples (see the source), most ADSL Home routers and Home WiFi Access points uses linux. You are using Linux.

Taking a screen shot in Ubuntu (and probably most GNU/Linux distributions) is basically by pressing your keyboard print screen button and then choosing where you want to save a PNG image of your screen without any additional applications required.

Steps:
1. Press Print Screen
2. Click on the Save button (or Choose a folder other than the default then Save)

I always use the middle (3rd) mouse button to open links in new tabs (I keep a large number of tabs opened) faster than right click then open link in new tab but javascript links won't work when opening them in new tabs. Smart Middle Click extension fixes this problem.

As a hacker with the pseudonym Myria reports in a blog entry, once Skype is launched it saves an executable file called 1.com in the user's temporary folder. This file contains code that transmits the data found in the BIOS address area of the application to be launched. It is not yet clear what the Skype software does with the data, which may contain, among other things, the motherboard serial number. The mysterious .com file was only noticed because of an error message that Skype outputs when it is launched on systems running on 64-bit versions of Windows. 64-bit versions lack the "NT Virtual DOS Machine" (NTVDM), which allows direct access to BIOS memory pages and is required to execute the program. Since myria's blog entry is dated February the 6th 2007 presumably Skype added the BIOS reading code to their applications relatively recently.

Egypt calling code is +20 and it was never +2. If you are living in Egypt and you think its calling code is +2 then make no doubt about it, you are not too far from ignorance, you might just be few steps away.

You do not believe me? Ask Google.com for: Egypt calling code or visit Wikipedia.org Egypt page

DNS servers should only do recursive lookups for its own network but Link.net prefers to make it open for the whole world.
I reported this problem to link.net dnsadmin today hoping that they will get it fixed.

$ host 196.218.128.1
1.128.218.196.in-addr.arpa domain name pointer host-196.218.1.128.tedata.net.

I have reported this typo mistake to tedata.net 3 days ago but it was not fixed yet. Moreover, PTR records are not enough for complete Reverse DNS, A records should also be created for these hosts.

Jan 09 2007 Update: tedata.net removed the PTR records for this IP block.
Jan 10 2007 Update: tedata.net brought back the PTR records and still incorrect.
July 05 2007 Update: Reported fixed on June 7th in a comment, I just checked and it is fixed.
