  The 10 Greatest Hacks of My Life

My co-founder and I briefly considered applying to YCombinator for the Winter 2012 session. We eventually decided to bootstrap Curvio initially, and raise a seed round on our own after we launch (so far so good!). But looking over the YC application, one question intrigued me:Please tell us about the time you, tansey, most successfully hacked some (non-computer) system to your advantage.Now, there are a lot of ways to interpret this. A mechanical interpretation would be about...

  Why Windows?

Since the latest episodes of both Bent and Throw it Against the Wall have seen me mention Windows Phone 7, I think it’s about time I talk about why I like it. I know there’s a lot of scepticism surrounding it. And why not? Most people I know who were considering jumping the Microsoft ship did so in the dark days of Vista, so that’s their last experience with Windows. Anyone who saw their parents working on a Treo back in the nascent days of the Blackberry know the slop...

  Before Python

This morning I had a chat with the students at Google's CAPE program. Since I wrote up what I wanted to say I figured I might as well blog it here. Warning: this is pretty unedited (or else it would never be published :-).

  Fastjson just fixed a bug which might cause out of memory issue

Fastjson just fixed a bug which might cause service down a few days ago. This bug is caused by some mishandling of special character \x which is an escaped character to indicate hexdecimal number. The impact of this bug would be big if the attacker constructs a malicious data which would cause the service down.  The code which causes the issue is in com.alibaba.fastjson.parser.JSONLexerBase#scanString, when a JSON string is passed in, fastjson would parse the string character by c...

  In-memory key-value store in C, Go and Python

Subtitle: Wow Go’s net library is fast On paternity leave for my second child, I found myself writing an in-memory hashmap (a poor-man’s memcached), in Go, Python and C. I was wondering how hard it would be to replace memcached, if we wanted to do something unusual with our key-value store. I also wanted to compare the languages, and, well, I get bored easily! The code is on github as Key-Value-Polyglot. Each version implements enough of the get and set commands from the mem...

  memcpy() vs memmove() in C

memcpy() copies the bytes of data between memory blocks. If the block of memory overlaps, the function might not work properly. Use memmove() to deal with overlapping memory blocks. memmove() is very much like memcpy() but very flexible as it handles overlapping of memory blocks. example : char msg[50] = "abcdefghijklmnopqrstuvwxyz"; char temp[50]; main() { strcpy(temp, msg); printf("Original Msg = %s\n",temp); memcpy(temp+4, temp+16, 10); printf...
