"Maker" schedule vs. "Manager" schedule

Interesting post about how programmers think v/s managers think about meetings
http://www.paulgraham.com/makersschedule.html

I myself feel like if there is a meeting scheduled at 11 AM than between 8:00 - 11:00 AM I should not pick a task that takes more than 2-3 hours. The reason is that context switch is so expensive that if I leave a task in between than coming back and picking it up again will again require additional 15-20 mins to reestablish the context. Hats off to Paul for writing such a good post.

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()
