Continuous demand for growth together with free trade and the Internet have put all businesses under immense competitive pressure. Companies focusing on one or two unique selling points have to be competitive in every single possible event to stay in business. Working on cost and processes is something all companies can do but it is much more complicated to work with intangible assets like the perception of the company and its products and services. Still many very successful companies have built powerful brands often in combination with innovative business models. Efficient processes and cost control are hardly the primary reasons for the success of Apple, Google, Twitter, Skype and Facebook. Even for successful companies like IKEA – masters of efficient processes and cost control – their innovative business models and excellent branding are their main reason for success.
Every once in a while I find myself with the task of renewing our SSL certificates. Normally I would spend about 30 minutes searching the internet for the set of commands to generate all the files in the required formats (.pem, .csr, .p12, etc). Sounds quite simple and easy but it gets tedious and can consume quite some time as all steps must be carefully reviewed. So I created this handy script to automate the whole process.
Usually I would use apachetop. But some times you don’t have it installed in your server, and installing a web log analyzer (or any other software for that matter) is not always an option. In those cases I use this little one-liner that shows the hits per second in real time:
The Internet of Things is happening. It doesn’t matter if The Internet Of Things phrase has become a buzzword that is being used for almost anything; the reality is that it is happening right now. The idea of interconnecting everything to create a smart network of things has fascinated us for a long time, and we’ve been waiting for the refrigerator that identifies bad eggs and places an order at the local supermarket for far too long. We may not be there yet, but we are getting closer. That being said, where do we start? Read on to see a proof of concept using an Arduino Uno board and Ogangi’s M2M platform.
Some time ago we created an EBS backed LVM volume on Amazon EC2. The setup is working without issues and we have tested that our snapshots can be restored to another instance without consistency issues. Right now we need to increase the size of the volume as the data we store in it has been growing quite a lot. The process could not be simpler:
We have a very large monolithic database that we’ve recently migrated into Amazon EC2. This DB has been growing quite fast these past weeks, and we were about to hit the 1TB cap for EBS volumes on Amazon EC2. I’m not quite sure why do they have this limit, given the size of Amazon’s infrastructure, or why doesn’t Amazon offer an official alternative (like RAID1 via the Web Interface) to overcome this limitation. I’m quite sure this is a problem that is affecting a lot of customers, and attacking it would seem a priority to me.
