After comparing the configuration files, I discovered that the troubling variable is DB_CHARSET. The default config setting is ‘utf8′. But if you have been updating the software versions, your database table is [...]

This competes with Amazon.com’s SQS , S3 (storage) and EC2 (hosting) services which are used by many startups… The applications will get google’s massively scalable infrastructure, failover.

I keep forgetting some of the functions in excel and it is embarrassing to search for the same things every time.
PERMUT(n, r) = nPr = n! / (n - r)!
COMBIN(n, r) = nCr = n!/((n-r)!r!)
FACT(n) = n! = 1*2*3*…*n
BINOMDIST(s, n, p, cumul) Probability that there will be exactly s successes in n trials, each [...]

A beautiful song composed by Shankar-Ehsaan-Loy and sung by Shankar Mahadevan.
Lyrics by Gulzar
सन सना ता रा रे रारा सन सना
आसमाँ के पार शायद और कोई और आसमाँ होगा

ओ… मैं हवा के परों पे कहाँ जा रहा हूँ कहाँ
कभी उडता हुवा कभी मुडता हुवा मेरा रास्ता चला

Here are some recipes for interpreting stream of bytes as different C types. I will keep adding more to this as I go…
Convert a byte stream (embedded in a string) into 1 byte signed integers:
“\xfc\xfd\xfe\xff”.unpack(”c*”)
=> [-4, -3, -2, -1]
Convert a byte stream (embedded in a string) into 1 byte unsigned integers:
“\xfc\xfd\xfe\xff”.unpack(”C*”)
=> [252, 253, 254, 255]
