This change will require users to renew certificates on a nearly monthly basis. This is a manual process that will now have to be done up to 10 times per year, instead of just once. This change will not be evident to most Internet users and businesses. https://rietta.com/blog/unisuper-google-cloud-backup-failure-lessons-learned/ Mon, 03 Jun 2024 06:00:00 +0000 https://rietta.com/blog/unisuper-google-cloud-backup-failure-lessons-learned/ It has been reported that Google Cloud irrecoverably deleted the account of UniSuper, a $135 billion Australian pension fund. This happened when its account was wiped out due to a technical error on Google’s part. At the time, UniSuper indicated it had lost everything it had stored with Google, even its backups, and that caused two weeks of downtime for its 647,000 members. They were able to recover because their multi cloud strategy included data backup off the Google Cloud to another service [1, 2]. https://rietta.com/blog/aws-swap-file/ Thu, 04 Jun 2020 06:00:00 -0600 https://rietta.com/blog/aws-swap-file/ Amazon Web Services, or AWS, is the biggest provider of cloud computing services in the world. Even services like Heroku are a wrapper for AWS instances that applications sent to Heroku are deployed on. For developers first starting out with AWS, or for experimental applications that are intended for proof of concept or tech demos, the most cost-efficent way to deploy an application on AWS is to use the free tier of services. https://rietta.com/blog/find-top-referral-sources-with-raw-apache-access-log/ Sat, 22 Feb 2014 14:20:50 -0500 https://rietta.com/blog/find-top-referral-sources-with-raw-apache-access-log/ <p>In today&rsquo;s issue of the <a href="https://rietta.com/blog/categories/mastering-the-terminal/">Mastering the Terminal series</a>, I present to you the easy way to find your top website referral sources using only tools available on the Linux (or Unix) command line and your raw Apache access file.</p> https://rietta.com/blog/using-iptables-to-require-cloudflare/ Mon, 10 Sep 2012 00:00:00 +0000 https://rietta.com/blog/using-iptables-to-require-cloudflare/ For some of our clients, Rietta uses CloudFlare.com for its web application firewall and content distribution network (CDN) services. CloudFlare is installed on a domain by changing the domain&rsquo;s DNS servers to resolve to CloudFlare, which then proceeds to serve as a proxy between the web and the web server running the protected application. Once this is setup it is expected that all general web traffic will originate from the CloudFlare network, which is the proxy server. https://rietta.com/blog/wget-to-keep-new-rails-site-in-memory/ Tue, 10 Jul 2012 00:00:00 +0000 https://rietta.com/blog/wget-to-keep-new-rails-site-in-memory/ A Ruby on Rails web application can be really fast in production. However, for a site that receives less traffic the application can be very, very slow on the first request after it has gone dormant. One way to make sure that your site is always fast and never goes dormant is to setup an automatic process to periodically fetches the home page. On an Linux, FreeBSD, or Mac OS X system it is easy to setup an automatic fetch using cron and wget.
