A leech called Credit Card.

If you are one of the guys who just draws his/her credit card faster than Quickgun Murugan draws his gun out at the drop of a hat then this entry is for you.

There are a few rules one should always follow to make sure that the interest you pay on your debt is not making a hole in your pocket.

Rule No 1. Never keep your outstanding credit on your Credit Card. The interest rate is the highest and it will bleed you.

Rule No 2. Never borrow on your credit card  for the same reason.

Rule No 3. If in case your Credit Card ended up having a big outstanding, beg , borrow , steal , but clear the debt as you may not realize that  your are paying a bomb as an interest on your outstanding.

Rule No 4. Learn to use Credit card for transactions wisely and to your advantage. Know your billing cycle and you will never pay a dime more.

Rule No 5. Credit card buying is only for a stop gap arrangement and not to a medium to incur more debt for sure.

Rule No 6. Well if you need to borrow and you just have nothing to pledge then go for a personal loan for maybe 24 months or more. It will be a tad lesser than CREDIT CARD.

If you can altogether do without one then DUMPing your Credit Card for good could be a wise idea. Debit cards are accepted everywhere nowadays.

Protocol Buffers

Every time I see teams working on a new project , they say oh well, lets design the interfaces first. And then they again go through the draconian ritual of defining xml schemas and agree on data formats and the protocol. And I just hate XML and SOAP and all that's chatty. Every time programmers are figuring out newer inefficient mechanisms to parse data. The amount of time that is spent on this again is ridiculous and unjustified.

Now look at Jabber's protocol or the XMPP protocol as they call it. Hugely popular as it may be  , but its still pretty inefficient considering many times the xml envelop in which the payload is sent is several times heavier than the actual data itself. 

Usually the data construction and parsing logic has no error handling which can cause a small invalid data to crash the entire system This is often due to weak logic both on the sending party and receiving party.

I am hoping protobuf will address these issues. You are only considering what to exchange , the how factor is always figured. And yes you save some code as well.

Postgres gets Inbuilt Replication - Icing on the cake

For a couple of projects , I used postgres extensively. I like postgres a lot. Its a very robust database and even libpqxx client libraries have very neat error handling. I almost dumped it for mysql just beacuse mysql has inbuilt replication.

I gave Rubyrep a try and the initial tests results were very encouraging. For some reason I switched to the latest version of Postgres - 9.0 and what a surprise package it was.

Here is a small comparison between Postgres and Mysql replication.

I aint never going to Mysql ever. Postgres is the database for me.

VOIP on BIackberry without BIS and Internet

Sounds too good..yeah. thats what I thought when visited tringme's website. Tringme client for BlackBerry suppports SIP protocol and look what it says..

No Internet or BIS service needed
This is another great news! TringMe application works even if you do not have internet plan on your Blackberry. All operators offers both Email only or Email+Internet (BIS) plan for Blackberry. Many users does not opt for BIS and only uses Email only plan which is definitely cheaper. The downside of that is that most application will not run on Email only plan. If TringMe's application does not find any data connectivity, it uses Email channel to communicate and enables users to initiate calls even if they do not have internet plan.


SWEET !!

DroidPro - one more blackberry wanna be.

Motorola launched the next version of their Droid series which is an Android based phone. From the looks of it , it seems like its trying to lure blackberry users.

DroidPro

They can put in a Qwerty  key pad but how do they match RIM's messaging  and email service. Blackberry enjoys its status owing to the fact that its truly a complete flawless communication device for the business and professional community. Another reason Android phones don't really score with me is that most of the phones suck so badly at battery life.

Even what's more amazing is that a lot of the student community has been adopting Blackberry. That being said , I still keep the finest phone made till date:- My Blackberry 9700. The IPhone is for the kids.

Symbian Foundation shuts down by december 2010

And there are the androids, iphones and blackberries but symbian is still the most dominant OS on mobile phones today. Symbian and Nokia is still clueless about how to handle the licensing issues around their platform. It turned from commercial to free and now they are shutting down the nice looking site free symbian goodies saying Nokia is reworking licensing of the Symbian platform and the free stuff will be available through an alternative open and direct channel.

Nokia is definately not being open and direct about this one.

Here is what symbian.org says

Nokia commits to make the Symbian platform available under an alternative open model


AMSTERDAM, SYMBIAN EXCHANGE & EXPOSITION (SEE), NOVEMBER 8, 2010 – Following a strategy review, the board of the Symbian Foundation has today decided to transition the role of the non-profit organisation. The foundation will become a legal entity responsible for licensing software and other intellectual property, such as the Symbian trademark. Nokia has committed to make the future development of the Symbian platform available to the ecosystem via an alternative direct and open model.


“The founding board members took a bold strategic step in setting up the foundation, which was absolutely the right decision at the time,” says Tim Holbrow, executive director, Symbian Foundation. “There has since been a seismic change in the mobile market but also more generally in the economy, which has led to a change in focus for some of our funding board members. The result of this is that the current governance structure for the Symbian platform – the foundation - is no longer appropriate.


“However, the platform enjoys strong support from some of the largest and most innovative device creators in the world. And we continue to see solid momentum behind the platform, with 25 percent of all Symbian-based devices shipping in the last 12 months.*
