I find interesting when faced a taken-for-granted situation, in particular in the tech world. This time’s history is about an Internet ADSL connection that allows all traffic but SSH. Yes, you read it correctly. It was very bizarre confirming such event was a real-life situation. I don’t claim to be a networking expert but at […]
Apache Phoenix is a relational database layer over HBase delivered as a client-embedded JDBC driver targeting low latency queries over HBase data. Apache Phoenix takes your SQL query, compiles it into a series of HBase scans, and orchestrates the running of those scans to produce regular JDBC result sets. What the above statement means for […]
How to get Movistar Peru (Internet Móvil) ZTE 3G MF193 modem to work under Debian jessie (unstable) with NetworkManager.
Couple of weeks ago I was in the situation of having to setup up a new laptop. I decided to go with wheezy’s DVD installer. So far so good. I didn’t expect (somewhere in the lies-I-tell-myself dept.) to have GNOME as the default Debian desktop. However after install I’ve figured it was the new GNOME3 […]
Update: I no longer use this key. Instead I’ve transitioned to a new key: D562EBBE. A bit late but I’ve created a new 4096 RSA GPG key. I’ve published a transition document as well. I hope I can meet fellow Debian developers soon to get my new key signed. So, if you are in town […]
Cloud is passing the hype curve and we are seeing more stable developments and offerings on the market. Lately I’ve been playing with RedHat’s Openshift. Openshift is a PaaS (Platform as a Service) offering that intends to be an alternative for vendors such as Heroku. The focus for such offerings is to give developers enough […]
Usually, when using Subversion’s SSH authentication facility, Subversion’s client will make use of your own SSH-generated key-pair and read it from the proper location, usually $HOME/.ssh. However, there could be situations when you’ll need to use a different key-pair. In such situations you can use a nice trick to have svn+ssh authentication work smoothly. Let’s […]
Using s3tools to interact with a S3-compatible storage service for non-Amazon providers.
While setting a puppet agent to talk to my puppetmaster I’ve got this weird SSL error: Error: SSL_read:: pkcs1 padding too short Debugging both on the agent and master sides didn’t offered much information. On the master: puppet master –no-daemonize –debug On the agent: puppet agent –test –debug Although I had my master using 3.0.1 […]
I do like the way programmers think in terms of DRY, for instance, among other forms of optimization. A couple of days ago I wanted to test different implementations of the same algorithm in C++. The usual approach would be to implement those algorithms, call them in main() and see the results. A more interesting […]
