What Is Cron?
In simple terms, cron is a job scheduler in unix-like operating systems. It is also called as system cron or OS cron especially if the discussion is also about WP Cron. The job can be anything that needs to be done at a particular time. The job could be an one-time job (such as launching a rocket at a scheduled time) or repetitive (such as turning the lights on upon sunset and turning them off upon sunrise, every day!). Basically, the system cron is a program that runs all the time just to trigger a particular action at a particular time. You can throw hundreds of tasks on it to do at various intervals. System cron is like robot who is always available at your service!

WordPress Object Cache system allows transients to be stored in object cache backend, such as APC, Memcached or Redis. Without an object cache, the transients are stored in the database itself. This is the default. You could verify this yourself by looking at the (wp_)options table in the database. Fortunately, we have options to store these transients in the memory using one of the backends mentioned above. Among these, Redis has become stable and is production-ready. There are two WP plugins available that use Redis as WP Object Cache. First one is Eric Mann’s plugin. The second plugin is by Till Krüss who forked the former and made it better.

My first blog post was written way back in 2011. Since then, I have written only 33 articles (excluding this). Considering, I always keep a (physical) diary of events and thoughts, it is nothing but a low volume blog. This year, I wish to write more. So, I will be participating in 52 Week Writing Challenge. I already have a few ideas in my mind to start with.

Often, I create a development site, such as dev.example.com, test.example.com or staging.example.com, before making any change in the production site. I even have a dedicated server to host the dev site of all my clients. If you don’t have a development site on your own, please do create it. It’d save you a lot of time in the future. Your production site might become overnight success and you can’t afford to tryout important changes in the production site.

Web server market is dominated by Apache HTTP server that enjoys its status because of its open source nature and because of its role in bringing the masses to the world wide web. Without it, we may not have had so many web hosts and web sites. However, its memory footprint has been a concern until today.
Nginx is the second largest in terms of Web Servers Market Share. While Nginx is still open source, the constant upselling of its commercial subscription may not be welcomed by everyone. Don’t get me wrong. I use Nginx too for its low memory footprint and its efficiency in serving static files.
Microsoft’s IIS is third most popular web server. It is rock solid, having its own use cases.
OpenLiteSpeed is very limited in its functionality.

Today is the day when Google has started implementing mobile friendliness as a search engine ranking factor. The actual announcement in this regard was done two months ago in the official WebMasterCentral blog. It also started showing a tiny warning in the official blog since then. If you use WordPress and if your site is not mobile friendly, yet, there are options to convert it (for free) to fit into mobiles nicely.

Last month, a WordPress site with a fairly active forum (related to Beatles) needed to be migrated to another server. The forum had a new post at least every 30 minutes, including on week ends when the traffic to the site is the lowest.
This is the rough overview of the process: Continue reading “Mitigating DNS worries while changing hosts!”
