It was a Boring Saturday again :P
So jus started exploring Brain F**K an awesome weird programming language
It has got just 8 alphabets + - < > , . [ ] that's it :)
This is like Maagi of programming languages :D
U wanna know the C representation of Brain F**K
char array[30000];
char *pointer;
That's it :) It has a global array of size 30000 with a pointer pointing to it :)
So I'm curious and tried this oneSo now UR curious? Jus Click the link to Execute this
1. Copy paste the code
2. Type some Name r the One u like in the input Eg. xxx'\n'
('\n' - For clarity it is actually Enter in ur keyboard.)
Don't forget to hit an enter at the end of the name else the code ll stuck in infinite loop
3. And Execute it :)
4. Don't laugh you are a culprit :P :P Who is that guy r girl? :D
I'm done :) U also wanna explore? U have one link ahead Brain F**K
Setting up chrome/firefox in linux based x86_64 EC2 instance In this post we'll see how to setup chrome/firefox in EC2 instance. Further we'll discuss the way to setup chromedriver with selenium [java] in EC2 instance aswell. Why is that difficult? Linux based EC2 instances lack gtk+ , which is a must to launch any GUI enabled applications. How to solve? Compile gtk+ from source. This gist by joekiller has the complete dependency tree resolved for installing gtk+ for x86_64 machines. Line 77 Basically installs firefox from its tarball. You can comment it out incase if you don't wish to. Incase Line 42 fails. Do a wget for direct tarball from here , instead the complex recursive wget. For Ex: wget http://releases.mozilla.org/pub/mozilla.org/firefox/releases/latest/linux-x86_64/en-US/firefox-18.0.2.tar.bz2 So, All done? Nopes, Now we can't run either of the browsers as we lack X11 server which does graphics operations & screen outputing. As our envir...
Hi, I think now I'm eligible to publish a blog post regd CQL. I wish this blog to be a tutorial rather a Syntax provider for various CQL queries Points to remember 1. CQL doesn't support Composite Types[likely to chage] 2. CQL doesn't support Super columns 3. Counter values are returned in native format [atleast in php/using cqlsh] Why should I prefer CQL? 1. Readability 2. Ease of use 3. SQL like 4. Stable Support: PHP => My Posts using PHPCassa Python => Refer Here and Download it here Java => JDBC Driver and Example is here Ruby => This might help Creating a Keyspace: cqlsh> CREATE KEYSPACE sample WITH strategy_class = 'org.apache.cassandra.locator.SimpleStrategy' ... AND strategy_options:replication_factor = 2; Note: : => Option Specifier Use a Keyspace: cqlsh> USE sample; Note: Don't forget to USE before use 'Sample' and 'sample' are different. Create Column Family: cqlsh...
After lots of googling I figured out how to access counter columns value via PHPCassa + CQL. Though it might not be efficient, this is all I was able to figure out after a long struggle :) First Connecting to and Selection from Cassandra Instance via PHP using PHPCassa $pool = new ConnectionPool("Stats",$servers); $raw = $pool->get(); $rows = $raw->client->execute_cql_query("SELECT 'a' FROM Impressions WHERE KEY='xxx'", cassandra_Compression::NONE); To Return Connection $pool->return_connection($this->raw); To Update Counter value via PHPCassa $pool = new ConnectionPool("Stats",$servers); $raw = $pool->get(); $rows = $raw->client->execute_cql_query("UPDATE TestCounter SET 'counter'='counter'+1 WHERE KEY='xxx'", cassandra_Compression::NONE); You can find a wrapper here So, once you are done with fetch successfully. This is the result you may get object(cassandra_CqlResult)#...
