Belgacom TV has said its customer base grew by 75,000 customers compared to 52,000 for the same period last year. “The number of net adds in the third quarter 2009 was positively influenced by the launch of “FAIR”, a company-wide programme to address cable competition,” according to the incumbent.

One of the reasons cited by the operator is the launch of the “Free TV” campaign, which refers to the monthly saving customers realize by signing up for this offer. The launch of new multi-play offer in July 2009 led to an all-time high sales figure for bundled offers (the so-called ‘Packs’) and Belgacom TV, adding respectively 70,000 and 75,000 customers in the third quarter 2009.

By end of September 2009, the total Belgacom TV customer base amounted to 663,000, including 88,000 second stream users. In one year time, Belgacom’s TV customer base grew by 220,000 customers. The continued customer growth is the main driver of the Belgacom TV revenue growth.

Compared to September 2008, the revenue grew by 51.2% to €94 million and now contributes for 5% to the total CBU revenue.

The television ARPU per household end of September 2009 was €20.10, or an increase of 1.8% compared to a year ago, driven by a lower impact of promotions. The third quarter ARPU of €20.6 significantly improved compared to the previous quarter as a result of increased sales of set-top boxes and slightly higher usage of on-demand services.

Solving slow weblogic startup in Linux

Sometimes you can have a lot of propblems starting Weblogic under linux. It can sometimes take ages before the Weblogic really starts.

Turns out Weblogic uses random number generator during start up.

Because of the bug in java it reads ‘randomness’ from /dev/random. /dev/random is very good random numbers generators but it is extremely slow.

It can take sometimes 10 minutes or more to generate one number. /dev/urandom is not that good, but it is instant.

Java somehow maps /dev/urandom file to /dev/random. That’s why default settings in $JAVA_HOME/jre/lib/security/java.security are useless.

Possible solutions:

Add “-Djava.security.egd=file:/dev/./urandom” (/dev/urandom does not work) to java parameters.

mv /dev/random /dev/random.ORIG ; ln /dev/urandom /dev/random

Best solution is to change $JAVA_HOME/jre/lib/security/java.security

Replace securerandom.source with
securerandom.source=file:/dev/./urandom

Then try to start the web
