Warning for Newbies using LiveCD/DVDs

Warning for Newbies Using Live CD/DVDs

It is an advantage to use PAE based distributions.

PAE stands  for Physical Address Extension (32 and 64 bits machines)

Now that it very easy to obtain a Linux Live there are certain prerequisites or conditions one must satisfy before experimenting with them. I would list some of the mistakes I have done and continue to make in spite of the familiarity. Some of them I call killer sharks. The take over the entire system with minimum warning and they forget Live Booting is fun and game and there should no be any commitment to them like Microsoft Apple Mac as from the box.

1. First priority is the graphic capability. NVidia is the graphic card Linux find it easy to configure. Lot of manufacturers do not provide necessary OEM data for Linux to configure them. If you have the wrong card you may not be able to join the fun. They may boot up bit might do some damage to the card. The damage may be due to wrong low level configuration or due to graphic intensity of the distribution. One example is SuSe which is graphic intensive KDE. On the other hand it may be like Swift Linux with low graphic intensity with the mind set for old computers and may not be suitable for graphic card with much power.

2. Second is the RAM. I recommend minimum of 1 GiB but more the merrier then the live session will be quite fast to boot and execute its virtues.

3. Third is the monitor. Lot of old distribution cannot configure LCD monitors. I of course in my early days with wrong horizontal and vertical configuration burnt few cathodes out of commission. Now of course most distributions tell you it has not got the driver for the card and uses the least harmful configuration for the live sessions.

4. If you have got a hard disk without an operating system or data no harm can be done. I often use the live session for preparing the hard disk. Partitioning and formatting can be done to get the hang of the process but with Operating system and data in the hard disk and no changes to the hard should be done without saving data.

5. Doing any of these without a UPS power supply is a risk. If power fails one should immediately terminate the session.

What can go wrong for Android Tablets?

Lot can go wrong with Android tablets.
This was posted in 2011 and Google has improved.
I started using an android and testing it on real time.
I will post you with my updates, some of them are already in asokaplus.
Long period elapsed from the concept to execution and most of it was tested on high end of the market.
The average user was not involved in the decision making.
It was probably an effort of a small team which worked hard (dedicated to the task at hand). To begin with it was the development of the browser. Then the tiny OS without security enhancements.
It was a new browser not a time tested one.
There were many suitable candidates for this new browser in the  Linux community and none of them were considered or compared with the Chrome. 
Now take FireFox.
It has lot of loop holes when used in the Microsoft Environment.
It originated from Linux but then arched its way out to embrace Microsoft community.
With that it lost the security features.
It is possible to customize it in the Linux environment and even in that environment some cookies till lately (penetrated even my computer) do some undesirable things.
I was doing lot of downloads without a firewall and hacker (most likely windows guy from India-that is far as I went in search of the guy) installed a script in the browser.
Fortunately I detected it in matter of hours and took necessary steps.
Instead of point to point I went for Torrents which has a way of of using the port and testing the threads.
Even torrents can be attacked and it happened to LinuxTracker and lately Linux foundation is affected by a similar attack.
If Linux could be attacked it is going to be chicken feed for attackers in Microsoft environment.
Chrome will have to deal with this threat.
It has no human resource to deal with like in the Linux Community.
In a commercial environment Linux does not prosper as was shown in Fedora Project.
Fedora’s contribution was marginal when compared to Debian.
It was today I (rather PCLinux) detected something fishy.
I was using point to point download overnight (two files) and one of them (either Zenwalk or Absolute Linux let in a cookie in between the download streams disrupting my download (point to point) today.
Equally it could have happened after the downloads were finished and I did not terminate the download as usual and left the computer running.
If I had the torrent running this would not have happened which I usually do.
I removed all the Google Cookies (including useful ones) to get some sanity back and system running smoothly.
Any browser is vulnerable and not foolhardy.
So Google gadgets are also vulnerable.
In any case I do not use Chrome.
I am into Cloud computing I have to and I will be using the browsers.
I think Linux has to develop a utility like torrent to deal with this problem and Google with its limited staff cannot do that.
For cloud to succeed something better than the browser has to take the  tiny  computing moments and events into control.
I believe the browser is not the best vehicle for Cloud computing.
Time will tell whether my apprehensions are true or false.
Google cannot do it alone.
The stakes are high if they fail. 
Like viruses for Microsoft viruses it will be Cookies for Google that set in a bad omen (for Chrome and Google).
It has to forge a friendship with Linux Community for it to be successful.
The mistake it did was to declare it’s kernel is pure and original. It is not and it is vulnerable.
Linux has to look forward to the challenge and take a giant stride now  (before it is too late) in Cloud Computing.
Linux can do it with or without Google’s help. That is my belief.

WordPress Web Hosting

WordPress is a Open Source Content Management System (C.M.S) that provides a simple web application platform for web hosting.

If you a Linux geek you can download it and tweak it to satisfy your needs but the open license prevents you from developing new themes other than what is already agreed and known as the standard.


It probably developed from
Ubuntu Turnkey applications and has a significant market share of web hosting for smaller companies. 
My intention here is to let you know that there is http://www.wordpress.org that gives you a blog space like here in Google’s blogspot that can be your personal web site before you mature into a Web Wizard. 

Other reason for me to
highlight it here, is that it has support for Sinhala fonts and Tamil fonts for your web writings. 

Do not wait till Government provides you with necessary infrastructure in IT including fonts, go and become a Web Star (not a Mega Star) by learning the basics with WordPress

It is easy as a word processing program and you will ascend to greater heights once you master the Codes.

A glossary of the Codecs are published elsewhere free for access.

It is free but once you are mature you can pay a nominal fee and upgrade your blog site which for me is almost a complimentary website without annoying advertisements that hide your creativity.

I downloaded
WordPress some months ago but failed to write something about it since I was obsessed with Linux 100 Live CDs. 

Now I am quietly delving into inner strengths of Linux and Open Source talking about WordPress is appropriate here.

The omission was a serious lapse on my part and my apologies for that.

WordPress
is as important as Dropbox for new wave of web activity with cloud computing on the horizon.
