The System Administrator will often come across a situation where an SSH connection to Host B is only possible by making a detour via SHH to Host A: client -> ssh A -> ssh B To shorten this two-step process, an entry can be made in the ~/.ssh/config of Host A as "Jumphost", to ensure that this step is always followed in future.

Recursively finding Windows Internet Shortcut (*.url) files and changing them into GNOME desktop files Over the past few days I have finally converted my wife's computer from WinXP to Linux (Ubuntu 10.10). One of the many fine points of the negotiation leading to this was that I needed to preserve her many Internet Shortcut files. Since she has literally thousands of them, and they are sprinkled about in many a nested folder, I needed a script that could find them, and create the equivalent GNOME desktop files. The following is my solution. Perhaps not the most elegant way to achieve these ends, but it worked great for me. However I cannot promise this script will not eat your files, so please test and use at your own risk ;-) Create the following script (e.g. using vi)

I've been asked on at least three separate occasions lately how to know if changing a particular postgresql.conf item requires a restart, or a reload, of PostgreSQL. Here is my quick and dirty favorite way to answer this question:
-- configs requiring postgresql restart
select name, setting, context
from pg_settings where context = 'postmaster';
-- configs requiring postgresql reload
select name, setting, context
from pg_settings where context = 'sighup';

When you pass large amounts of data to and from PL/R, quite a lot of time is needed for converting. A change is being tested which treats arrays of 4 byte integers and 8 byte floating point values as a special case, resulting in a dramatic performance improvement. In a recent post, I discussed PL/R performance related to seismic timeseries data stored as an array of floats that are all recorded during some seismic event at a constant sampling rate. The problem was that when dealing with, say, 14000 arrays of floats, each having on the order of 16000 elements, passing the data to and from PL/R proved slower than hoped.

The vast majority of Debian installations are simplified with the use of Preseeding and Netboot. Friedrich Weber, a school student on a work experience placement with us at our German office has observed the process and captured it in a Howto here: Imagine the following situation: you find yourself with ten to twenty brand new Notebooks and the opportunity to install them with Debian and customise to your own taste. In any case it would be great fun to manually perform the Debian installation and configuration on each Notebook. This is where Debian Preseed comes into play. The concept is simple and self-explanatory; usually, whoever is doing the installation will be faced with a number of issues during the process (e.g.

nVidia has made it known that the free nv Driver is no longer going to be supported. Starting with the newly publicised Fermi Graphics Cards, future cards from nVidia will no longer work with nv Drivers. Originally, nv Drivers from nVidia were developed to provide basic 2D performance. 3D support was neither wanted nor planned in the open driver, users with 3D requirements have always been referred to proprietary drivers from nVidia. In future, the nv driver will no longer be maintained and all users are referred to the proprietary drivers.
