Linux for Older PCs : From Ubuntu to Vector Linux

My linux journey began with Red Hat and Corel Linux, in the 90s. For a long time, I just couldn't convince my dad to install linux on his windows laptop, the only computer we had then. Then came the 21st century, with linux distros getting more user-friendly with easier and manual-free installations. I shifted from being a long time RedHat Fedora fanboy to an interim PCLinuxOS fan to finally an Ubuntu believer.

Finally after 2 long years, this week, I decided to move on a bit, and try something new. My PC is getting older and constantly struggles to carry the huge processing needs for the latest KDE4 or Gnome and the delicious compiz, which has now become an integral part of the entire Linux Experience.

This week, I tried Vector Linux, a slackware based distro, known to be fast and stable, ideal for older machines like mine and yet never compromising on the features. Read on, to see if it delivered what it promised.


Before we start, here is my PC configuration. It's an old Compax nx7010 business laptop with a Pentium M(Centrino) 1.6 Ghz processor, 1.5GB of Ram and a 64 MB ATI Radeon 9200 gfx card. It's pretty fancy for a 5 year old laptop, but it cost a bomb back then.

I downloaded the VL 5.9 Standard Edition iso from the Vector Linux Homepage and gave it a try.


1. Installation
VL has a decently friendly text-based installer. I found it easy at most times but the partition tool still needs some rework. If you are not comfortable using fdisk or similar text based partition utilities, I would suggest creating the swap and root partitions beforehand using gparted or something else, and just select them for installation. It is a lot easier this way.
The installation was really really fast, finished in less that 20 minutes. Lilo autodetects other OSs on your system and configures easily. VL also prompts you to configure xorg and suggests drivers for your card. In my case, fglrx doesn't work for older ATI cards (pre Radeon 9550), so I selected the opensource radeon drivers. You can also configure your network settings. The system reboots to boot into your new VL environment.

2.Interface, design and usability
VL uses Xfce as it's default desktop/window manager. It also comes with jvm, fluxbox and other light alternatives. The default Xfce environment looks really polished with Thunar being the default file manager.


It's nice to log in as Root for a change, though it is never recommended. On top of the standard xfce applications set, VL offers its own control center called VASM where you can configure - display, network, boot systems etc.


Another nice addition is the package manager GSLAPT, which looks like a skinnier half brother of synaptic but has everything you will ever need to install the extra packages.


Overall, for newbees it's a pretty friendly experience, and seasonal Xfce users will be delighted with the VASM and SLAPT.

2.Quirks, Pains and Woes
I am really tempted to recommend it to everyone, but no OS is perfect, including VL. Firstly, I wasn't really impressed with the partition tool in the installer. Secondly, newbees who select the wrong graphics driver will be left wondering why their Xorg crashes with "no screen found" each and every time they do "startx". Thirdly, the built in wifi configuration in VASM refused to obtain an IP address from my d-link router. VL comes with Wifi-Radar, which again gave the same message. I finally had to get Kdenetwork manager, just to get my wifi connected. Users from other distros - Ubuntu, Suse, Fedora etc. will definitely miss the extensive package support in Vector Linux, which currently has a limited package repository. There are some articles online, which talk about using Slackware packages directly on VL, which I still need to read. Overall some hits and some misses.

3. Final verdict
Once all the initial quirks are resolved (especially the xorg issue), VL is a really solid distro. It is fast as expected from Xfce.
For older machines, fluxbox is a really nice alternative. VL packs a wbar, a mac like dock on startup, which can be activated for Xfce with following command.

$ wbar -above-desk -pos bottom -isize 40 -nanim 5



The best way to really speed up things is by choosing a lower desktop resolution. It really works but would you wish to give up your crisp high resolution for a faded 16 bit low res? The choice is yours, speed vs looks. And yeah, forget compiz. The last one really hurt.. right? Enjoy your linux experience, and please do give VL a try. I am off to try Mandriva 2009 RC2, but I have a gut feeling, I will be back again to VL. Have a nice weekend folks!

Test driving the new Ubuntu 8.10: Intrepid Ibex Alpha6

A few days back, Ubuntu announced the release of the alpha6 of the next Ubuntu release, titled as Intrepid Ibex. Along with a new version of the kernel and X.org server, it has some useful improvements. Here is a sneak peak of what to expect from the next release.

A gentle reminder, please don't try this on a production Environment.
Now, let us get started shall we.
Fire up your update manager, from System > Administration > Update manager or

$ sudo update-manager -d





Update manager will ..prompt the availability of 8.10 in the repos. Click on "Upgrade".



Sit back and relax, as the update starts. Restart the machine to complete installation and Voila, the new system is ready for testing.


Great, now let us look at some of the new improvements that Ibex has to offer.

1. An Improved Network Manager

• With 3G Support
  
• you don’t have to log in to connect (this is also of of the most requested features),
• PPP and PPPOE connections management,
• management of many active devices.

2. Synaptic

• Improved interface
• Auto completion of search results (no need to click search)
  

3. Nautilius

• Finally! Tabbed browsing
  

4. Private Folders

Ubuntu now offers your own personal protected (chmod 700) and encrypted folders under ~/Private. In alpha execute the following to get this feature.

$ sudo apt-get install ecryptfs-utils auth-client-config
$ sudo auth-client-config -p ecryptfs_standard \\
-t pam-auth,pam-session,pam-password ecryptfs-setup-private

5. Guest Accounts
Ibex will have a new "Guest" account. Guests have almost no rights. They have no access to other users’ files and they cannot save any files permanently (guest’s home directory is temporary). This is a nice security feature if you want to give your friends' a internet browsing access or for other simple tasks, without compromising your system's security.

Final Word,
From the regular end-users' perspective, the alpha6 has nothing ground breaking to offer. Most of the new features are good to have, but not a must to have. You see the difference right.I didn't encounter any major issues using the alpha, but if you have a stable 8.04 working on your box, I would suggest waiting for the final 8.10 release. But, if you are feeling a little adventurous, just like me, go one and give it a try. You won't regret it.
Enjoy the Ubuntu Experience and keep supporting the Open Source community. Thanks.

What have I been up to lately

This is another filler post. Blogging time is hard to come by these days, with a full time job which keeps me quite occupied throughout the week. Here is the list of posts that I am hoping to complete by this weekend.

1. A review on the online money management site : Buxfer
2. Sneak peak into the upcoming Ubuntu 8.10: test driving Intrepid Ibex alpha6
3. OSs for older machines - Ubuntu vs Vector Linux

Browsers get Speedier and the competition heats up...

This is more like a filler post as I hardly have time to blog on weekdays. This week had so many really interesting things happening in the tech world that I just couldn't help ..myself.

Google loves to hog the limelight and they did it again in great style by releasing "Chrome", the google branded web browser based on WebKit. Touted as the fastest and safest browser ever, with a new Javascript virtual machine called V8, and a multiprocess approach to individual tabs, Chrome is an amazing experience. I tested it on my office Vista machine, and it was clean, easy to use, light and really fast. First impression, an awesome "A". As firefox is blocked in office, and Chrome surprising installs without Vista prompting me for an Admin password, I can see how Chrome easily replaces ie7 for me in my workplace.

To make things more interesting, Brendan from Mozilla posted results of their own new Javascript engine Tracemonkey for their next generation browser Firefox 3.1, on his blog, showing how it kicks chrome's butt in the SunSpider Benchmarks.
I did a quick test and found it really snappy and fast compared to the current Firefox 3. It's still an alpha so don't expect great things from it yet :).

The already saturated Browser market has yet another competitor, which surprisingly has the potential to outshine the leaders. But the fox is still not out of the race yet. M$'s got a lot of work to do now, if it still wants to keep up in the race.

I am still waiting for Chrome's native linux version. Or else, will have to use Wine to run it, but then that's for the weekend. Good Night everyone.

Test Driving the new Thunderbird3 alpha2 (Shredder) on Linux

Feeling a little adventurous today? Want to get your hands dirty on something cool and really alpha. Here is something for you all.
The nice folks at mozilla spunoff Thunderbird into a separate project called Mozilla Messaging with a prime objective of developing Thunderbird3 (codenamed Shredder), the next generation open-source email/messaging client.

Some of the notable enhancements in Thunderbird 3 would be the integration of Lightening (a calendar extension), improved search and some configuration and user interface improvements.

A gentle warning, it is not meant for production environments. Let us start, shall we

1. Download the linux version of Shredder alpha2.

2. Extract the contents to a local folder (in my case Desktop).

3. Browse to the folder and Run the application by either from shell (as below) or by double clicking on a binary file called "thunderbird".



$ ~/Desktop/thunderbird/thunderbird


4. Thunderbird launches with a welcome screen, where you can configure your accounts (in my case, Gmail)


5. Like Thunderbird2, setting up Gmail accounts is a breeze. Enter your username and password, and you are done. Note: it sets up pop access.


6. You can specify all your account settings like before.



I wasn't expecting any new features as Shredder alpha2 is meant to test the transition to the latest gecko 1.9 engine, on which firefox3 is also based upon. Play around and if you do find bugs, report it back.
Well, that's it, happy alpha testing and keep supporting the mozilla foundation.

Google Insights: Finding Paris for Danes

Numbers intrigue me a lot. For instance, did you know, more Danes have searched for Paris Hilton, than anywhere in the world in the last 30 days(including the Americas). And did you also know, Obama has a huge fan following in Kenya.
There was a time when collecting statistics such as ..these would have taken months and even years. But now, by just observing user browsing and searching patterns, a lot of really interesting and sometimes useful information can be collected in no time at all.

We discussed Twist, few months back which analyzes Twitter posts. But, then how many people really use twitter? What is it that almost the entire world uses, more frequently than anything else? This might help you.



If you answered "Google", you are almost right. Though lately, there has been a huge shift towards social networking - Facebook and Myspace and stuff. But, one has to admit, Google knows more about people, than anyone else.

Google seems to have spun off "trends" as "Insights for Search". Insights analyzes user search behavior over the last 4 years across regions, cities and time lines. A statutory warning here: It's really quite addictive.

For instance, as a Linux enthusiast based in Singapore, I was disheartened by the fact that the awareness and interest for Linux has been falling continuously over the last 4 years. With this statistics, I know we've got to pull up our socks and try harder.



Another example could be, as a Microsoft X360 sales guy in Singapore, this following consumer trend is a warning bell to cut prices, increase awareness and throw in more promotions.



I could go on and on, but Google Insights is an amazing tool. It doesn't guarantee accuracy but paints a really interesting picture of what's buzzing the tubes. I only wish there was a way to filter positives from the negative "insights". Some things top the list for all the wrong reasons. But yeah, in future, context based searching will hopefully resolve this issue. Better not to discuss Cuil here :)

Insights showcases the amount of information Google collects. It also reinstates the reason why they are the biggest targeted online advertising agency. And it also reaffirms my faith in Google, that if there is anything to be searched online, Google will find it for here. God speed my friend and keep the numbers flowing :)

Cloud Computing: What it means for Enterprises?

Data is the single most important asset for any modern enterprise. Transaction histories, customer records, asset inventory lists, intellectual property, etc. Even the modern currency is just bits of 1s and 0s flowing through secure networks.

Data centers are the lifelines of such enterprises and companies spend millions, and sometimes billions to manage and run such data processing centers. Lately, due to rising costs in terms of maintenance, capital expenditures, enterprise licenses, power etc, companies are looking for cost effective alternatives. Analysts predict, by 2012 the power costs for running data centers will jump 13 folds. 60% of power consumed for cooling these centers is wasted due to inefficiency and there is a huge impetus to go green and be more power efficient in the long run.

A common technique followed by modern organizations to control rising costs is to consolidate a large number of scattered server farms, network rooms, communication centers and data centers around regions to smaller and centralized data centers. Also known as data center consolidation, this is a key driver behind reducing costs and optimizing existing resource by improving the utilization rates. Virtualization solutions like Vmware have also enabled better utilization rates by running multiple Os' and applications on a single server.

Cloud Computing views technology resources and infrastructure as "always on" services, where customers can tap into this vast pool to run their own applications and services. From the customer/end-user’s perspective, they only need to care about the subscription fees charged by the service provider. The Service Level Agreements (SLAs) ensure a minimum level of service quality and support.




Companies like IBM, Google, Amazon and Yahoo are the early promoters of this new phase in computing. Google which invested more than a billion USDs in Capital expenditure last year offers the Google App Engine service whereas Amazons S3 is quite popular among startups and SMEs who can’t afford to run and manage their own data centers.

Cloud computing in some sense, is a mirror of data center consolidation initiatives. Using Economies of Scale, by hosting applications from thousands of customers in centralized data centers, hosts increase the utilization rates of their existing systems, can negotiate with vendors for larger discounts, forecast energy requirements and can have a small set of on-site trained workforce along with a cheap outsourced support staff.

An important question that arises now is what keeps a modern day enterprise to shy away from cloud computing? In fact, isn’t reducing costs the prime focus of companies in such times of recession and economic slowdown?

Well, the answer is that it’s not that straight forward as it seems. Firstly, is it safe to trust a 3rd party to take care of your sensitive business data? Will your customers agree with it? What about regulatory requirements? Countries like Japan and Korea discourage the practice of storing local production data on international servers.

Moreover, some critical business applications can suffer from unacceptable latency issues due to the proximity and bandwidth connecting to the "cloud" network. In such cases, you have to fallback to your existing infrastructure resource or search for other "clouds" that would satisfy your latency requirements.

To sum up, Cloud computing seems like the right way forward. It's takes away the pain that comes with managing your own infrastructure. Along with the major technology breakthroughs, legal processes and controls are also needed in place before it can be accepted into mainstream. Service providers will have to work harder to build the trust amongst customers and guarantee a resilient, secure and stable infrastructure solution.

A lot of work is still needed but at least we are headed in the right direction. 2012 – Era of cloud Computing? Only Time will tell…
