I needed to extract certain Boost headers from its huge code base for memory mapped file & shared memory containers. The first idea came to my mind was a simple grep command for ‘#include’ statements and then parse the paths. This is simple but not so useful for the cases when headers are conditionally included. For example: #ifndef NO_STL #include… Read more →
To confess, this is the first time I write unit testing for Java & C++ and it turned out this was rather simple. This weekend Daniel is hosting hackathon at his place and invited Kong & me to come over. The first thing we did was TDD. Daniel was fluent in TDD & pair-programming as his company used Ruby and actively… Read more →
The NginX server from the Ubuntu LTS repo was 1.1.x and did not support WebSockets. The minimum version of NginX that supports WebSockets is 1.3.13. Note that supports comes in the proxy module. I upgraded to 1.4.1 by compiling from source and the proxy module is enabled by default. Now you can taste WebSockets via NginX proxy at http://pico.simpleit.us/ . Only valid… Read more →
After much consideration, I finally moved away from Apache & mod_php to NginX & PHP FPM. The site works much faster and no more I/O & CPU issues. I suspect my Apache was hacked last time, resulting in weird I/O behaviour and spikes in CPU usage. The next steps: Install uWSGI for Python and Ruby Run NodeJS behind NginX proxy… Read more →
I was cleaning up Apache config and removed the default 000-default & default-ssl from the Apache sites-enabled sub-folder. To my surprise the default page now goes to a web app that I did not expect. It took me a sec to realize 2 things: The first VirtualHost config that has format *:80 (HTTP) or *:443 (HTTPS) was considered the default… Read more →
Snow Leopard is supposed to be a slimmer and more stable version than Leopard. When it comes to default password input, Leopard is far better as Snow Leopard has a few drawbacks: 1. It cannot input password in languages other than English! Leopard did that just smoothly. 2. It does not have input language at password by default like Leopard…. Read more →
Previously I hosted all DNS records for simpleit.us with NearlyFreeSpeech (https://www.nearlyfreespeech.net/). They provide cheap DNS hosting at 1c/day per zone. Initially I didn’t hosted my DNS records with Linode as I was interested in redundancy. However, later I realized that I didn’t have any back-up/disaster recovery site on par with the VPS hosted with Linode. The account I have with… Read more →
Was not using this blog for quite a while as it lacked the features I needed such as reordering of the images in a gallery. Today I got an email from Posterous announcing a bundle of new features such as updated web editor, more flexible image/photo management and 2 new themes. I love the new theme named “Minimal” (currently in… Read more →
By default, Nokia Qt does not ship its Qt C++ framework with OpenSSL enabled. This degrades value of the framework and you won’t be able to access HTTPS pages or SSL enabled web services. The examples that require SSL won’t work as well. Take examples\webkit\googlechat for example. This post gives an approach to enable OpenSSL for Qt C++ framework on… Read more →
