Debian Maintainer Dashboard now provides iCalendar feeds

Contributors to Debian can now monitor their list of pending activities using iCalendar clients on their desktop or mobile device.

Github iCalendar issue feed now scans all repositories

The Github iCalendar feed has now been updated to scan issues in all of your repositories.

It is no longer necessary to list your repositories in the configuration file or remember to add new repositories to the configuration from time to time.

Get your Nagios issues as an iCalendar feed

The other day I demonstrated how to get your Github issues/bugs as an iCalendar feed.

I'm planning to take this concept further and I just whipped up another Python script, exposing Nagios issues as an iCalendar feed.

Get your Github issues as an iCalendar feed

I've just whipped up a Python script that renders Github issue lists from your favourite projects as an iCalendar feed.

The project is called github-icalendar. It uses Python Flask to expose the iCalendar feed over HTTP.

It is really easy to get up and running. All the dependencies are available on a modern Linux distribution, for example:

Quantifying the performance of the Microserver

In my earlier blog about choosing a storage controller, I mentioned that the Microserver's on-board AMD SB820M SATA controller doesn't quite let the SSDs perform at their best.

Just how bad is it?

I did run some tests with the fio benchmarking utility.

Lets have a look at those random writes, they simulate the workload of synchronous NFS write operations:

jSMPP project update, 2.1.1 and 2.2.1 releases

The jSMPP project on Github stopped processing pull requests over a year ago and appeared to be needing some help.

I've recently started hosting it under https://github.com/opentelecoms-org/jsmpp and tried to merge some of the backlog of pull requests myself.

There have been new releases:

Storage controllers for small Linux NFS networks

While contemplating the disk capacity upgrade for my Microserver at home, I've also been thinking about adding a proper storage controller.

Currently I just use the built-in controller in the Microserver. It is an AMD SB820M SATA controller. It is a bottleneck for the SSD IOPS.

Disk expansion

A persistent problem that I encounter with hard disks is the capacity limit. If only hard disks could expand like the Tardis.

Silent data loss exposed

I was moving a large number of image files around and decided to compare checksums after putting them in their new home.

Ouf of several thousand files, about 80GB of data, I found that seventeen of them had a checksum mismatch.

Running md5sum manually on each of those was showing a correct checksum, well, up until the sixth file and then I found this:

Lumicall: big steps forward, help needed

I've recently made more updates to Lumicall, the free, open source and secure alternative to Viber and Skype.
