But the latest language darling is probably the last one anyone expected. Believe it or not, 2011 could be the year of C++. Last week, the latest version of the ISO C++ Standard was approved by unanimous vote. It's the first major revision of the language in 13 years. Now officially known as C++11, the new standard introduces features desig...

  A possible way to recover deleted files on Linux

Last week I was generating a MD5 sum for an virtual machine image on one OpenNebula server: # ls -l test.img -rw-r--r-- 1 root root 10486808576 Oct 12 02:21 test.img # md5sum test.img At the same time I was clearing the files on the server on another terminal and deleted the above image file mistakenly with : # rm test.img Since this image file is 10GB, it took some time to remove this file from the server, so I used the Ctrl+Z command to suspend the remove command. [1]+ Stopped ...

I wrote a post about how to install MySQL++ and I thought I will write a quick tutorial on how to use it too. This is a very basic MySQL++ program and it’s very self explanatory: #include <mysql++.h> #include <stdlib.h>   using namespace std; using namespace mysqlpp;   int main() { try { Connection conn(false); conn.connect("DB NAME", "DB HOST probably localhost", "DB USER", "DB PASS"); Query query = conn.query(); } catch (BadQuery er...

Like many others, I tried “outsourcing my life” using a digital assistant. A year and a thousand bucks later, I’ve received one department store recommendation and an admittedly adequate spreadsheet of competitive research.I have since cancelled. Why didn’t it work for me?I think I just didn’t trust it/them/him/her (that I even have this ambiguity is indicative of the issues).Most of my mindless time-sinks involve at least a credit card number and are often a con...
