Dell lattitude 6430u drifting mouse pointer

Today i received  a brand new laptop shipped to my home  from my company. I opened it and booted it and immediately I realized something strange that I cant use the touchpad as no matter what I do the pointer would just drift randomly to one corner of the screen. I tried various options and I was surprised to see that even when I touch the sides of laptop that were not part of touchpad area the pointer would drift.  I thought may be its the first boot and somehow using keyboard I finished the initial windows boot. But again after restart same issue.

I plugged in an external mouse and it would work fine. I tried using the joystick pointer and it would also drift.

I tried various options and then thought I got a lemon or something went weird in shipping.  I read a forum about pressing Fn + F6 to disable joystick.  I tried that and it worked like a charm.

WTF this is second issue I saw with Dell, not sure what their QA team tested before certifying the laptop.  Anyways I work 90% using external mouse so I am ok.

I will anyways wipe windows clean and install ubuntu. Hoping I wont run into any more surprises.

Spring query timeout or transaction timeout

If you are using spring to manage transactions then you can specify default transaction timeout using

    <bean id="transactionManager"
        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />
        <property name="defaultTimeout" value="30" /> <!--30 sec--->             
    </bean>

or you can override the timeout in the annotation

    @Transactional(readOnly = false, timeout=30)


or if you are doing it programatic transactions then you can do


DataSourceTransactionManager transactionManager = new DataSourceTransactionManager(dataSource);
transactionManager.setDefaultTimeout(30);

 or you can override the timeout for one particular transaction

TransactionTemplate transactionTemplate = new TransactionTemplate();
transactionTemplate.setTimeout(30);

Python adding pid file

I have a thumbnail generator that launches multiple processes and the correct way to shut it down is to send kill -HUP to the parent process. To automate I had to write a pid file from python, it was a piece of cake
def writePidFile(): pid = str(os.getpid()) f = open('thumbnail_rabbit_consumer.pid', 'w') f.write(pid) f.close()
