Denying service to my own mail server

We had some intermittent problems recently with a mail server not being available. As it turns out, I basically was doing a “denial of service” attack on my own mail server, thanks to some caveats in how IMAP, push notifications, and my mobile email client, K9 work together. The problem One of the mail servers […]

Deploying a website with lftp

There still are web hosting providers offering only ftp access to your website files. No fun if you’re used to version control systems and shell access. I had to deal with that situation, and used Linux’s strength: combining several small tools.

Getting my GSM modem working under Ubuntu

Add new GSM connectionAnother “hack post”, to capture how I got mobile broadband working on my Sony laptop. Sony makes laptops with cutting-edge features (small, solid-state disk, full HD screen) and a stylish look, but doesn’t like to help you take full advantage of it unless you’re on Windows. Undocumented tweaks to the hardware, hard-to-find technical information, and so on.

I bought a Sony VPCZ1 (to be more precise: VPCZ13C5E) with a WWAN module installed, with the idea that I could be online anywhere, without any dongles sticking out, or having to connect by tethering it to my phone over Bluetooth or USB. I’ll pay the extra fee… provided it works.

I have installed Ubuntu 10.10 (which was an effort in itself), and went on an excursion to get mobile broadband running.

Hacking away on my Zim notebook

Working with open source is fun because it lets me explore software and change little things. If you’re not really into code and config files, you might want to skip this post 🙂

Zim task list (default)Zim task listSince some time I use Zim, a desktop wiki, to take notes in meetings and at conferences. It shares a few good things with Tomboy, the default notebook on Ubuntu (linking pages, immediately saving what you type so you don’t loose anything on sudden power loss) but has a few things I prefer:

  • Notes are stored as plain text: easier to use other text editors, version control, and scripts, and if for any reason Zim fails, I can still access my data quite easily.

  • The main interface makes organising and navigating notes easier.

  • The Task List plugin extracts lines with possible tasks, so it’s easier to keep track of follow-ups or actions in notes by simply typing a line like:

The Task List itself is a separate window you can pull up, to see all open to do’s. But I wanted to fix a few things to make it more powerful in daily use.

Tasktop to improve a knowledge worker’s productivity

I’ve been using Mylyn for quite some years now. Mylyn introduced the concept of task-focused work: activate a task in your to-do list, and only see the files relevant to that task. Tasktop, the company behind Mylyn, extends Mylyn as Tasktop, with even more features, and promises “improved productivity, guaranteed.”. It works great when I am developing software, and also could support me as knowledge worker, for instance by managing bookmarks and browser tabs in Firefox. But I’d like to see it offer more support for task management within Firefox too. A bit like this.

Switching from Beagle to Tracker and solving the performance problems

When I update my laptop to the next version of Ubuntu (Lucid Lynx or 10.04 this time), I usually have a look at the general direction for some of the “ desktop core elements”, like desktop search. I decided to switch from Beagle to Tracker and hopefully have tackled the performance problems it seems to come with.
