At last life can begin to return to normal in our household.  The final element of the kitchen project was the glass 'splashback' which went in behind the the cook-top this week. Yes, it is rather red.

The builders, engineers, joiners, plumbers, electricians, floor sander, carpet-layer, and glazer are all done.  The painter still has some finishing work to do outside and he'll be back in a couple of weeks once the putty has had time to cure.

The dingy 1970's look is all gone and in its place we have a light, airy, open and inviting space. Now all we have to do is pay for it.

The end is in sight at last. The painters have finished except for a little work outside. The new kitchen cabinetry was delivered today and is currently filling up all the space in the new kitchen.

The floor sander chap has been and done around those parts of the floor where the cabinets will stand. This means that when the installation is complete (and the builders in their work boots are gone) the main floor will be sanded without the need for the machine to get up close to the new cabinets.
The kids are demo'ing the platform I built for wallpaper stripping and painting of the wall by the stairs. Because the ceiling is so high I needed something solid enough to support a small step ladder. There's no doubt, this thing is solid. I'll almost be sad to see it go but it takes up too much space in the garage. So if you want it and you have a dollar you might get lucky.

Since the last release of SSHMenu went so smoothly, I thought I might as well do another...

SSHMenu is somewhat of an enigma - it's a GUI tool for people who work at the command-line. In theory it shouldn't appeal to the point-and-click crowd (since they don't use command-lines) and it also shouldn't appeal to the command-line crowd (since they don't use GUIs). Of course the world is not black and white and most people choose the combination of tools that work best for them.

I lean strongly towards the command-line myself and yet I developed SSHMenu because I wanted a GUI solution to a particular problem. I wanted to be able to easily initiate a new SSH connection in a new terminal window. I wanted the ability to define the position and size of the new window and to use colours to indicate the class of machine the window was connected to (eg: production vs test vs development). The solution that worked for me was to implement an applet that provides a menu of frequently used connections.

It turns out that there are some people who also want to be able to set up profiles for frequently used connections, but they don't want to use a menu. When they're typing at a command prompt and want a new SSH window, they don't want to reach for the mouse - they'd prefer to type a command. Release 3.18 of SSHMenu adds a feature to support this group of users. Now they can use SSHMenu's GUI dialog for the infrequent task of defining a new connection, but for the frequent task of initiating a connection they can use the command-line.

Here's an example. Say you have a server called 'fitzy' that hosts your web development environment. Perhaps you frequently connect to this host to run 'tail' against the Apache error log. Since the lines of output tend to be quite long you prefer to use a small font and a wide window positioned across the the bottom of your screen. You can set that all up using SSHMenu's 'Host' dialog:

And now you can initiate the connection in a new window with this command:

    sshmenu-gnome fitzy

Of course 'sshmenu-gnome' is rather a long and unweildy command to type frequently so it's likely that you'd alias it to something shorter like 'connect' or 'sshm'. The SSHMenu distribution includes a bash completion function called _sshmenu which allows you to do tab completion of host definition titles from the command line. If you set up an alias for the main command, you'll want to associate the completion function with your alias as well:

    alias sshm=sshmenu-gnome
    complete -F _sshmenu sshm

So there you go. If you like to use multiple terminal windows it might be a useful addition to your toolbox.

I finally got around to pushing out a new release of SSHMenu. It includes some bug fixes, minor tweaks and one particularly cool new feature. As I'm sure you'll recall SSHMenu is a very simple GNOME panel applet that provides a menu of hosts for you to connect to via SSH. Point ... click ... shell window appears:

The advantage of this system is that when you define a host connection you get to specify things like the window size and position, terminal profile (for font size and colour, etc.), SSH connection parameters (e.g.: username or port forwarding options) and even a command to run on the target host (e.g.: tailing a log file).

The disadvantage of course, is that you have to define at least some of those things - you can't use SSHMenu to connect to a host unless you've defined a connection. Following a suggestion from Chris Siebenmann, release 3.17 has changed that. Now the applet includes a handy little text entry box.  Type a hostname in the box, hit Enter and you're connected. Even better, the text box does auto-completion so if you've connected to a host before then you can type in the first few letters and select the host from the list:

The available options for auto-completion include:

• hostnames you've typed in the box previously
• hosts that are already defined in your menu
• an option to take the hostname you've just typed and add it to your menu

The history file for the auto-completion box lives in $HOME/.sshmenu_history. You can open this file in a text editor and paste in a list of hostnames from your DNS zone file to pre-seed the auto-completion list. At this stage there's no way to remove things from your history file other than with a text editor but I hope to fix that in a future release.

Now for the bad news ...

You can't actually use this cool new feature yet.  Earlier this year Detlef Reichl did some work on the Ruby-GTK bindings to add some features to the panelapplet library that he needed for his teatime applet. His patches were accepted and released in version 0.19 of the bindings. Two of those patches are required to run the new features in SSHMenu. Version 0.19 of the bindings has made it into Debian 'unstable' and hopefully will be in the next Ubuntu release. Until then, if you want this feature then you're going to have to build the libraries yourself.

And finally ... while I was developing this new feature I took the opportunity to move the source code from Subversion to Git. What a blessed relief!

Thomas and I have discovered some great books together and the Wellington City Libraries have served us well. When finding books for Thomas I'm obviously influenced by what I was reading at his age but we made some great new discoveries together.

Paul Jennings' writing is designed to ignite a passion for reading - especially in boys. His stories are always intriguing and importantly they're also not overly long. I found a collection of many of his stories in one large book. Thomas worked his way through one story at a time and before he knew it he'd read a whole book! Having proved to himself that he was capable of reading a 'proper' sized book he then launched into reading the Harry Potter series.
Unintimidating books are important for building confidence in a young reader. Some other titles Thomas enjoyed included Jon Scieszka's Time Warp Trio series; any of Roald Dahl's kids' books; Zizou Corder's Lion Boy series and anything by Louis Sachar (including the fantastic 'Holes').
One of my all-time favourites when I was young was Willard Price's Adventure series. Thomas also enjoyed that series but sadly he never shared my passion for Arthur Ransome's Swallows and Amazons books.
Eoin Colfer's Artemis Fowl series are great adventures, intelligently crafted and funny to boot. Thomas initially enjoyed these books but then went off the whole fairy theme. He rediscovered the series a couple of years later and devoured the lot - elevating Colfer to 'favourite author' status. Another of Colfer's books that we particularly enjoyed (aside from the Artemis Fowl titles) was 'The Supernaturalist'.
The Septimus Heap series from Angie Sage was a hit with the whole family and these were the first 'big' books that Emily read. Still on the theme of magic and dragons, the Eragon series from Christopher Paolini is probably at the top of Thomas' all-time favourites list. Emily Rodda's Deltora Quest books would be high on his list too.

When the Alex Rider 'Stormbreaker' movie first came out Thomas and I both read through all Anthony Horowitz's Alex Rider books. An older cousin then turned Thomas onto the Power of Five series which targets more mature readers and he ripped through those in short order.

Recently Thomas and I have been reading the Pendragon series from D J MacHale. I've got to admit that the quality of writing is not exactly first class (the books read more like screenplays than novels) but they're gripping stories all the same. I'm just working my way through book 9 in the series so despite my reservations there's obviously something that keeps me reading.
We both read and enjoyed 'Tunnels' by Brian Williams and Roderick Gordon. When the followup book 'Deeper' appeared, Thomas tried it but got bored and gave up. I tried it too and also got bored. Eventually (about 3/4 of the way through the book) the story finally got going and by the end I was actually enjoying it although I really didn't sympathise with any of the characters. When the third book 'Freefall' was released I read it and enjoyed it despite the plot having proceeded well beyond any last vestige of plausability. I don't know how many books are planned but I hope it's not more than four.
As I've said here before, John Marsden's Tomorrow series is high (possibly top) on my all-time favourites list. The quality of the writing is excellent and the characters began to feel like members of our family. It's probably a little old for Thomas but I'm confident it will grab him eventually.

Unfortunately the technique of picking books that appeal to me, simply doesn't work when I'm finding reading material for Emily. She does enjoy reading but doesn't get immersed to the same degree as Thomas (her run with Angie Sage's books being the exception to that rule). She'll be turning 10 soon and is a capable reader so if anyone can suggest great books for girls I'd love to hear from you.

I was looking through the 'Young Adult' fiction section at the library and came across this classification.  Someone was having fun ...

It's all rather exciting! After I left for work this morning the builders moved in and the demolition work began ...

The aim of the project is to add some dining/living space (we're not sure which yet) to the kitchen by extending through into what is currently a laundry. The laundry was a rather large room and included a shower that we never used and a toilet that didn't work.

One of the windows will be removed altogether and in front of it we'll have a cupboard laundry containing the washer + dryer + tub. One of the other windows will be removed and replaced with french doors. There's a long way to go yet but at least we have professionals on the job.

Just in case there's a programmer left on the planet who hasn't seen this link:

James Iry's ‘A Brief, Incomplete, and Mostly Wrong History of Programming Languages’

Yes, it's geek humour but it's very funny geek humour!

OK, so my headline may be exaggerated but lately I've been reading "The Tomorrow Series" by Australian author John Marsden and Wow! These are awesome books.  If you haven't read them, start now:

The main thing that impressed me about the series was how well written they are. The characters are realistic and believable and I really cared what happened to them. In fact it might be said I cared too much. When things went well I enjoyed their successes.  When things went badly I felt a physical knot in my stomach as I read on to find out how things would be resolved.

It is tempting to describe what the books are about. Indeed I have enthusiastically succumbed to that temptation with friends and acquaintances as I worked my way through the series. Despite my enthusiasm I saw people's eyes glaze over as they thought things like "I don't read kids book", or "I don't read war stories", or "blokey adventure books aren't my thing". The books definitely don't fit into those pigeon holes but I can see how someone might mistakenly think that they did. It would be a real shame if I put you off reading these books because you will love them.

This link has been doing the rounds.  Apparently it's hilarious. I like to think I have a sense of humour, but I just don't get the joke.

My best guess is that it's 'funny' because the text doesn't fit in the box. There are two fairly obvious possibilities: either the box isn't big enough or the text font size is too big. Either one would be trivial to fix with a line of CSS. In fact you could easily do it in such a way that if the user chose to increase their browser font size the box width would increase too. An alternative possibility is that the wrong text is in the box. The box might have been designed to contain a certain type of data and the text that's ended up there is not what the box was designed to cope with. Maybe in this case the best thing to do is to simply hide the 'overflow' since it shouldn't be there anyway. Once again, you can achieve that easily with one line of CSS.

Still guessing here, it's probably also 'funny' because this would never happen if you laid out your page with tables instead of CSS. I'm not sure if that's actually true but if you did specify a width on your table and then you put data in it that was too big then most browsers would ignore your width setting and increase the table size. Is that the right thing for the browser to do? Probably not. It certainly has the potential to screw up the rest of your page layout and relying on the browser to do something other than the specific thing you asked it to do would seem a risky proposition at best.

The whole tables vs CSS 'dichotomy' is nonsense anyway. They are not mutually exclusive and they each have their strengths (I certainly don't want to try and lay out tabular data using only CSS). At least with CSS you have this option:
