A couple of experiences recently have reminded me that I ought to rely more on profilers when debugging performance problems. Usually I'll start with logging/printing or inline REPLs to figure out where the time is taking, but in heavily iterative functions, a profiler identifies the cause much more quickly.

1. Augeas path expression performance

Two users mentioned that Augeas's path expression performance was terrible in some circumstances. One was working on an Augeas provider for Puppet and it was slow matching entries when there were hundreds or thousands of services defined in a Nagios config, while netcf developers reported the utility was very...

I’d like to stop all re-shared posts appearing in my Facebook feed, and only
see newly created content from my contacts. Is this possible?

The problem with being the engine of your business is that, sometimes, engines stall.

Recovering now.

Discovering the IndieWeb movement was a 2015 highlight for me. It addressed many of my concerns about the direction of the modern internet, especially regarding ownership and control over that data.  But to truly own your own data, self-hosting is a must!

Background: Self-hosting your own stuff

I’m an ideas person. I have a number of projects – or, rather, project ideas – lined up, which I need to record and review. My blog provides me with the ideal space for that, as some ideas may attract the attention of others who are also interested. But why does this matter?

As someone who naturally likes to share experiences and knowledge, I see no benefit in not sharing my ideas too....

In my recent post on the Bac Posture Stand I mentioned that I had purchased the Varidesk Pro Plus 48. I promised to review this "in due course" and that time has now come!

The Varidesk Pro Plus 48 is "desk riser" that enables you to choose your working height. You can start the day standing up and then, after your executive lunch, you can spend your...

Where we require a lightweight mail client, we tend to use Sylpheed, a fork of the old Claws Mail.

It seems unlikely that you would be able to add an ActiveDirectory Address Book into such a lightweight email client, and indeed the manual states:

### FIXME: write this part.

But in fact it was trivially easy:


Whilst these instructions worked for us, do be aware that we are using Samba4 ActiveDirectory. In theory this is a drop-in replacement for Windows ActiveDirectory and these instructions should work unchanged.

Add LDAP Addressbook

Firstly run Sylpheed and go to Tools and Addressbook. Within the Sylpheed Addressbook...

After much research I decided to purchase ESET Antivirus for our Windows clients. But rather than install ESET Antivirus on each client in turn, I decided to install ESET Remote Administrator on an Ubuntu VPS. ESET Remote Administrator is a server program for controlling ESET Antivirus (and other ESET programs) on clients, you can use it to deploy the ESET Agent, which in turn can then install and monitor the ESET Antivirus software.

Our Windows PCs are controlled by an ActiveDirectory server (actually a Samba4 ActiveDirectory server, although that should not make any difference to these instructions).

I found the...

I have a problem with a Samsung M3 Portable USB3 external hard drive only working intermittently. I use a couple of these for off-site backups for work and so I need them working reliably. In fairness a reboot does cure the problem, but I hate that as a solution.

To troubleshoot this problem, the first step was to check the system devices:

# ls -al /dev/disk/by-id

But only my main two system drives were showing, and not the USB3 drive, which would have been sdc, being the third drive (a, b, c).

System Logs

The next step was to check the system logs:

# dmesg | tail

This showed no issues at all. Then I checked syslog:

# tail /var/log/syslog

This was completely empty, and had not been written to for almost a year. I can't quite believe I...
