There are no clear guidelines to follow when you have to decide which one is better the old Myisam or the transaction based innodb.  In my experience the choice will differ from application to application and  database operations that are frequently used. 

Innodb comes with all the transactional database goodies and it is the choice if the database will be used as the OLTP with good number of reads and writes on it, It needs foreign key constraints . The table sizes aren’t big and the joins in the queries aren’t many.

But if the number of operations have to read most of the time and the application don’t require transaction control you must not overlook Myisam because it can give the kind of  boost to your databse performance no other DBMS can compete with. Suppose if number of writes are more then every time a table is updated it will be locked for other operation this is not a problem with innodb which is row based.

nnoDB is a largely ACID (Atomicity, Consistency, Isolation, Durability) engine, built to guarantee consistency and durability. It does this through a transaction log (with the option of a two-phase commit if you have the binary log enabled), a double-write buffer and automatic checksumming and checksum validation of database pages.Myisam isn’t crash safe and  if things go wrong getting db from the backup is the only choice.

Never think of mixed engine tables  unless it is absolutely necessary. The mixed type table will give trouble at replication and at the time of backup.Performance analyzing and balancing will be difficult and slow. If a crash happens then  to recover it wont be easy either.

Kaminey is a hatke masala movie first of its kind in bollywood history. While the critics are putting it in the tarantino style movies but there are many differences. You must watch it twice to have a opinion about it.  Other than the title of movie and glimpses of the past in between there is nothing else common with pulp fiction  or reservoir dogs. Vishal bhardwaj have his own style while all his previous movies are slow and spontaneous kaminey progresses too fast there are too many stories mingling with each other and central characters are twin brothers who hate each other. unlike of all the twin characters of bollywood they have a same accent and have a common problem with speech but they lives separately and when the need arises they are willing to sacrifice life of each other. The cinematography is best of the bollywood and the credit goes to tassaduq hussain who have earlier worked in omkara. I liked the go charlie scene which is filmed in a five star mumbai hotel. Producers presents it like a action movie of the 70s with all the guns , goons and dishum dishum. But the dhen te nan is more in the first half of drama then the final climax. The movie might not be popular with the naive indian movie goers but the urban class and the young generation will certainly like it. The movie should be watched by all the cinema goers as one critic have rightly put “like it or leave it you can not ignore it”. Other than the lead pair shahid and priyanka almost every character in the movie have a experience in stage acting. But shahid and priyanka are too good with acting particularly shahid is brilliant with most part of the movie the camera is on him. Amole gupta is great as a mee marathi manus politician of mumbai who hate all the outsiders coming to bombay. Though the movie is not yet opened in bombay because of swine flu there are many dialogs which are not understandable to non marathi peoples and the subtitles are in english for the part where african smugglers are conversing and also there were dialogs which are in english and bengali too. The creator are not at all taking the vast audience of bollywood in consideration. Earlier the language problem have hit the star studded omkara which have so many of its dialogs in the west U.P  dialects that was not understandable to vast indian audience who have missed their share of laughs because they cannot understand the words being sad. But that did not discouraged the director to do a similar thing in his next movie. The dialogs were pretty good and my favorite of all is when charlie says

waat iffey nahin lagti ki tu konfa rafta chunta hai.waat lagti hai iffe ki tu konfa rafta chodta hai.

The music is really good as in all the director’s movies and the songs and dance are in the sync with the story. Like both omkara and maqbool kaminey have one fast beat song, one public gathering song, one intimate romantic song and one is a slow song. Sung and picturised in the way with vishal bhardwaj stamp all over them.

Sometime ago I got a domain from yahoo domains service. I searched for the domain and selected to buy. somewhere midway in the process i left for some other task till the time i came back i wasn’t sure if i had already done the payment process and the interface which is much cleaner then godaddy or the likes but with unclear messages did not help. I clicked for something like deactivate so that i don’t have to be charged and i will complete the process from beginning.But the interfaces weren’t clearly conveyed it to me that i already got the domain and my payments have been accepted and most important what exactly the deactivate means there.

I got 2-3 mails from them first one order confirmed last one cancelled confirmed. So now i was clear that i have been charged and i cannot even access my account so i wrote to the support and they replied back that i must reactivate again.I did but now i was charged again for the domain which by the order receipt i already owned. So i wrote again to the customer support and he wrote since he cannot access the billing information i must contact billing department at: the rest is template mail.I never contacted them again.

Another one is of the auto bill pay service of icici which i wanted for my phone bills and after doing all the confirnation this and confirmation that they never activated it.Then again after a year they contacted me and apologised for last time but this time they will certainly do it may be some more months after.My vodafone number did not worked for a month because the customer care executive cannot get my address verified.  There are others from the SBI demat service, standard chartered and Bajaj allianz. The list is long the best option looks like to keep them away and live life like old fashioned way.
