  Guide on recovering data in MySQL

In our daily work, there might be mistakes made which got some data or even databases deleted in MySQL. If this happens on production, it would be a nightmare. In case this happens, normally DBA would jump in to save the world. And they would try to recover the data from the backup if there is any. But if there is no backup, then the show stops. Hence database backup is necessary on production environments to avoid such awkward situation. Also normally in MySQL, binlog should be enabled as well ...

  India: The World's Secret Silicon Valley

You might not know it, but a key cog in the global innovation machine is hiding in plain sight in the world's largest democracyReutersFor many firms, developing new products for consumers around the world is the most visible manifestation of innovation - the "real deal." But many people still see India as a place where other people's ideas are made or executed and not where innovation begins. (After all, you don't hear about an Indian equivalent to Google, iPod or Viagra.) Bu they're wrong. In m...

  Use pdb to help understand python program

  As I have mentioned in Why do I need a debugger?: (3) Debugger is a good tool to help you understand code. So when I come across difficulty to understand vfscount.py code in bcc project, I know it is time to resort to pdb, python's debugger, to help me. The thing which confuses me is here: counts = b.get_table("counts") for k, v in sorted(counts.items(), key=lambda counts: counts[1].value): print("%-16x %-26s %8d" % (k.ip, b.ksym(k.ip), v.val...

  Useful Bash Scripts

Many people hack together shell scripts quickly to do simple tasks, but these soon take on a life of their own. Unfortunately shell scripts are full of subtle effects which result in scripts failing in unusual ways. It's possible to write scripts which minimise these problems. In this article, I explain several techniques for writing robust bash scripts. Use set -u ...

  Why I left Google

Ok, I relent. Everyone wants to know why I left and answering individually isn’t scaling so here it is, laid out in its long form. Read a little (I get to the punch line in the 3rd paragraph) or read it all. But a warning in advance: there is no drama here, no tell-all, no former colleagues bashed and nothing more than you couldn’t already surmise from what’s happening in the press these days surrounding Google and its attitudes toward user privacy and software develo...

  Stop Making Apps

There are a bunch of iPhone apps I own though I have no clue what they do. These apps include but aren’t limited to; FLUD, Apptitude, Cartoonatic, Can’t Wait!, Punch, Pah, Prize Claw, Traveler, Concur, Jajah, Fast Customer, Pimple Popper and many more whose names I can’t even remember.Occupying my valuable homescreen real estate are also a bunch of apps whose purpose I remember only because they were built by people I know or am friends with, but that I sadly never use. And ...

  Why Do Some People Learn Faster?

The physicist Niels Bohr once defined an expert as “a person who has made all the mistakes that can be made in a very narrow field.” Bohr’s quip summarizes one of the essential lessons of learning, which is that people learn how to get it right by getting it wrong again and again. Education isn’t magic. Education is the wisdom wrung from failure. A new study, forthcoming in Psychological Science, and led by Jason Moser at Michigan State University, expands on this ...

  Why I Still Use Emacs

At school, I’m known as the Emacs guy; when people have questions about configuring Emacs or making it work a certain way, they often come and ask me. Sometimes, some people ask me why use Emacs at all? Isn’t it a really old editor and aren’t Eclipse or Visual Studio much better? I mean, they don’t have weird key bindings and have intellisense, that’s surely better for a programmer, right? I will attempt in this post to explain some of the reasons why I still c...
