Google Convoy

Spotted this when doing street view around Pyrmont Sydney – there’s at least two Google cars since one has captured this picture, looks like there might even be a third….

The watchers are watching the watched.

Unsure why there would be a convoy of cars, the few occasions when I’ve seen Google imaging cars in the past, they’ve always been standalone. Having said that, Pyrmont contains Google’s Australian headquarters, so maybe there’s a few special projects on the go.

linux.conf.au 2013 plans

It’s nearing that important time of year that the NZ-AU open source flock congregate that important and time honoured tradition of linux.conf.au. I’ve said plenty about this conference in the past, going to make an effort to write a lot more this year about the conference.

There’s a bit of concern this year that there might not be a team ready to take up the mantle for 2014, unfortunately linux.conf.au is a victim of it’s own success – as each year has grown bigger and better, it’s at the stage where a lot of volunteers consider it too daunting to take it on themselves. Hopefully a team has managed to put together a credible bid for 2014, it would be sad to lose this amazing conference.

As I’m now living in Sydney, I can actually get to this year’s conference via a business class coach service which is way cheaper than flying, and really just as fast once taking the hassles of getting to the airport, going through security and flying into account. Avoiding the security theatre is a good enough reason for me really – I travel a lot, but I actually really hate all the messing about.

If you’re attending the conference and departing from Sydney (or flying into Sydney from NZ to then transfer to Canberra), I’d also suggest this bus service – feel free to join me on my booked bus if you want a chat buddy:

  • Depart Sydney, Sunday 27th Jan at 11:45 on bus GX273.
  • Depart Canberra, Saturday 2nd Feb at 14:00 on bus GX284.

The bus has WiFi and power and extra leg room, so should be pretty good if you want to laptop the whole way in style – for about $35 each way.

Museum of Contemporary Art Australia

On one of our trips down to Circular Quay, we recently discovered the Museum of Contemporary Art Australia.

It’s a free museum with a range of interesting and unique exhibits and worth visiting if you have a couple of hours time to spare – since it’s right on Circular Quay it’s really easy to get to, plus it’s also right by The Rocks which is worth a visit.

The MCA was a really good visit, well worth checking out if you have time in Sydney – plus it’s free, which is a miracle for Sydney really. ;-)

Based on how much I enjoyed MCA, I’m even more keen to make a trip down to Tasmania in the near future to go visit MONA – I sadly missed it on my last trip as it hadn’t quite opened at that stage, but hearing lots of awesome stuff about it.

Sydney’s Powerhouse Museum

The Powerhouse Museum in Sydney is a science/tech/design museum offering a range of exhibits including space, robotics, history, fashion and other geeky and design related topics.

I went there on a special event day so the usual $12 entrance fee had been halved (yay!) and spent a few hours having a good look around the museum.

No tech museum would be complete without a steam exhibit – the powerhouse actually has some of the engines in a powered state, although there wasn’t a whole lot going on when I was there.

Before data centers, these were the power houses of industry.

There’s also a good exhibit of space technology, including an actual F-1 rocket engine, the most powerful liquid fuelled rocket ever developed and the machine responsible for powering the Saturn V which took humanity to the moon.

At times the selection of exhibits feels a bit disjointed, things certainly don’t flow quite as well as some of the other science and technology museums I’ve been to and some areas a bit worn and dated –  having said that, they are in the process of renovations, so it might be fairer to re-evaluate it in a year or so.

That being said, it’s worth a visit, just for some of the awesomeness they have there – plus how often can you take a picture of you and your partner standing underneath an F1 rocket engine? :-)

Bondi Beach

Seeing as I’m living in Sydney, I felt compelled to head out to visit Bondi Beach – it’s a pretty famous location, so figured it’s worth getting out there to check it out at least once.

All set up for a day at the beach, geek style!

All set up for a day at the beach, geek style!

Getting out to Bondi is a bit of a mission, since unfortunately the rail link doesn’t go the whole way – instead you catch the train to Bondi Junction, and then switch to bus in order to get to the beach.

You can buy a (pricey) ticket at any of the city train station machines that includes both the train and bus fare – costing about $8.80 return at an off-peak time.

The bus is the worst part of the trip, in future I’ll probably consider just walking it as it’s only 3.2km from the railway station – whilst the buses *do* have air con, any benefits are lost with the squeeze with numerous tourists squished into it, personally I’d rather be hot outside than hot squeezed into a metal tin with random strangers….

Bondi Beach. It has sand. Waves. Usual beach things really.

People are really the biggest issue with Bondi – it’s a nice beach in it’s own right, but the volume of tourists and shops around it kind of ruins the enjoyment somewhat, particularly when combined with the transport hassles. In summer the crowds can be massive, as much as 30 thousand+ – and it’s not a particularly large beach really.

The smaller beaches in walking distance to the south like Tarramara and Bronte look more appealing if you’re more of an introverted type, or take the ferry over to Manly for some of the nice beaches over there.

If you’re a tourist on holiday, you’re probably better off spending your time in Sydney to explore the city and waterfront and save the beach trips for when visiting Brisbane’s gold coast.

Having said that, if you’re in Sydney and don’t mind lots of people, it’s a nice beach and looks great for swimming and surfing, plus it’s well patrolled by surf life savers.

One of the perks of Bondi Beach is being able to meet pretty ladies.

Aside from the beach, there are a large number of eateries along the beach and in the surrounding streets – (like Funky Pies for some delicious vegetarian/vegan goodness), as well as a walk up over the rocky cliffs.

Looking back at Bondi

It was worth the visit, but I don’t think Bondi will become one of my regular visited locations, the transport hassles make it a bit difficult to get there – it’s easier for me to get out to Manly on the ferry than it is to get to Bondi on the train/bus.

It would be a different story if living locally or having a private transport option- some of my colleagues at work get there by bike which seems to work quite well for them.

Das Keyboard Ultimate Silent

With the recent move to Sydney, I’ve had to leave my beloved IBM Model M keyboards back in New Zealand – sadly they’re a bit heavy and large to effectively pack into my luggage without sacrificing some much needed clothes.

Even if I was to bring them over here to Australia with me, the Model M’s are too loud for me to use in a shared office environment – my Model M was previously banned from my last employers office after they could hear it through two walls and down a phone at the other end….

Instead I’ve brought a Das Keyboard Ultimate Silent. I’ve been a fan of the Das Keyboard idea for a while – just like the IBM Model M they’re traditional clicky mechanical keyboards, but have modern features such as USB, lighter bodies and (love them or hate them) Windows keys that are useful for both Windows and MacOS users.

Das Keyboards come in both labelled (Professional) and unlabelled (Ultimate) revisions, and the option of either standard loud clicky keys or the “silent” model – considering I’m working in a shared office space, I elected to go for the silent edition.

Mmmmm sleek black sexiness.

Mmmmm sleek black sexiness.

I’ve been using the Ultimate Silent for about two months now, general impressions are:

  • It’s an excellent keyboard that’s well worth the $150 AUD price tag. I’ve had heaps of comments from co-workers on how great it feels to type on, command line power geeks can’t be wrong. ;-)
  • The keys still have the tactile feedback of a mechanical clicky keyboard. Whilst the responsive spring-back is a little more subdued than on the Model Ms, it still delivers a very nice feel.
  • The blank keys are AWESOME. People who try to use my computer are always really put off at first, however if you’re a touch typist it won’t take long to get used to it.
  • It’s not exactly silent -“quieter” is a more accurate term, I certainly have the loudest keyboard in the office, but it’s nowhere near as loud as an actual Model M is. The sound is more a subdued tap as the keys hit the bottom of the keyboard when typing, rather than the audible click of a traditional clicky keyboard.
  • My colleagues are a pretty good bunch of people since they haven’t murdered me for loudly typing and stretching the “silent” label to the limits. ;-)
  • I have occasional issues with finding a particular symbol key (things like ^ or &), but I can touch type almost any of the 104 keys on it without an issue.

Personally I’ll keep using the IBM Model Ms as my personal keyboard, they’re great quality keyboards and I love the fact I can keep using something designed in 1980s (mine were manufactured in 1994) on my computer for possible the rest of my life, but I’d be very content with using a Das Keyboard personally as well as professionally if I didn’t already have the Model M.

It always amazes me how often geeks will spend huge money on their computers and then neglect the keyboard or buy something that features lots of flashy lights and special keys, but ignore the most important requirement of good typing ergonomics and performance.

I haven’t tried the clicky version of the Das Keyboard myself so I can’t really compare it – I expect you’d find that the clicky version has a even nicer feedback (like the Model M) but the silent is the better investment if you work near anyone else.

I brought mine from AusPCMarket who have local stock and it arrived in a couple of working days without an issue, otherwise buy direct from Das Keyboards.

Light Rail of Sydney

Ending up living in Sydney rather than Melbourne has brought one unfortunate side effect – a lack of awesome trams spread around the city. Thankfully it turns out one doesn’t have to go all the way to Melbourne just to get a light rail fix.

Sydney has two forms of light rails – the monorail which is to be decommissioned in 2013 and the more recent tram link that runs from Central station, through Pyrmont and out into Glebe.

mmmmmm light rail here, light rail there, light rail everywhere!

I haven’t been on the Sydney trams yet, based on the location of my apartment, central station and my office in Pyrmont, the tram tends to take me away from the direction I want to actually travel in – although that being said it may be useful if I ever want to go quickly from work to Central station and then transit onto the commuter rail network.

I’m hoping that Sydney considers adopting more light rail – whilst the commuter rail network is very effective at linking main centers, there’s a lot of Sydney that’s only linked by buses, which aren’t particularly fast and seem to be at their limits in regards to capacity.

Extending the tram lines out to places like Surry Hills and Bondi would be a huge plus, the linking of commuter rail and light rail has been very successful for Melbourne and there’s no reason why it couldn’t be replicated here as well.

Sydney Harbour Bridge Walk

One of my biggest annoyances about living in Auckland is that the only way to cross the Auckland Harbour Bridge was via car or bus –  so whilst my apartment would have been within feasible walking distance to the city, it was utter impossible to walk it.

Sydney has at least got this right and their famous harbour bridge is crossed by car, train, cycle and foot, which offers an excellent chance to see the bridge up close and get some amazing views over the city and harbour.

Views don’t get much more iconic than this. Amazingly hot dude and some building thingy in the background.

It’s an easy walk to get to if you’re a tourist – you just need to take the Northern Rail line Central, Wynward or Town Hall train stations and depart at the Milsons Point railway station on the North Shore, which is right where the bridge crossing starts for both pedestrians and cyclists.

Both the train and driving across the bridge offer views, but it’s nowhere near as excellent as checking it out on foot – and of course driving across will incur you some lovely tolls.

It’s hard to get a sense of scale – for reference there are two rail lines running through the right side tower, each capable of fitting a double decker train though it – or in the case of the left side, a road lane and a pedestrian path.

If I find my current 1 bedroom CBD apartment rent painful, I’d hate to think how much these places would be costing…

Sydney Opera House!

There’s one metric fuckload of steel in this.

It’s also really high!

Circular Quay, the international passenger terminal for cruise ships and the rocks.

I love these apartments at the city end of the bridge for being a neat varying stack of towers and roof gardens, but at the same time hate it’s blocky concreteness.

Interspersed concrete and greenary awaits at the end of the crossing – descend the steps to end up in “The Rocks”, the heritage part of Sydney

The crossing is well worth doing, it’s a real shame that Auckland hasn’t added a walk and cycleway of their own – not only is it a great recreational addition, but it also makes the lifestyle choice of walking or cycling to work from the North Shore feasible.

Australian National Maritime Museum

As part of my daily walk to work in Pyrmont, I pass the impressive Australian National Maritime Museum – considering they have both a Destroyer and a submarine parked in the harbor outside, I could hardly resist a visit for long. :-)

The museum has the usual range of maritime artifacts, exhibits about life at see, immigration, ship guns and steam engines, as well as a few neat items such as a maritime helicopter and small yachts and motor boats suspended inside.

Weird helicopter – kind of looks like some weird bug when viewed from underneath.

Of course for me, the real attraction was what was parked outside…

Above or below, either way we have your warfare needs sorted. :-)

Nowhere near as large as the cruise ships that now dock at Sydney, but still impressive when looking at them up close.

The best part is that yes, you can board both the destroyer and the submarine and explore them for yourselves! Unfortunately the day that I was there the submarine was closed, but I’m sure I’ll be back at some point and able to go inside it to explore more.

I had a good wander around the HMAS Vampire, a 1956 darling class destroyer built in Australia, and the last generation of warships before weapon systems moved from traditional cannons/big guns to missile based systems.

If you filmed a porno here, the title would be “one shade of gray”.

Military budgets don’t seem to extend towards having normal height ceilings.

Bit obsolete in the age of the drones and smart bombs, but nothing is quite as impressive as some big cannons.

I love the sci-fi look to these AA cannons.

Pyrmont Bridge with the wooden boat festival in the foreground.

Fuck your NBN and your UFB, fibre to the warship is where it’s at!

Server rooms have come a long way since. :-)

More computer users need to keep this in mind.

Early generation Nagios outage notification device?

Boom, boom, boom, boom, boom.

I can’t resist some good thick chains…. ;-)

Sir, we have a firing solution for the Apple store from the front turret!

I love warning signs like these “this shit be bad bro, try not to hang around here”

The rounds fired by these machine guns must be massive… probably tear a small boat apart.

Standing on the deck of the weapon of the 20th century looking out at the new weapons of the 21st century…. mega corporations.

If your target is too quick to move, there’s also the smaller patrol boats you can use to chase them down. They can’t have been too comfortable to spend time on, even sitting at the dock on a calm day the boat had a noticeable rocking to it.

The little offspring of the destroyer?

Whilst I couldn’t get inside on this trip, I got some great pictures of the HMAS Oberon diseal-electric submarine parked up alongside the destroyer. Whilst it’s not hard to find warships at maritime museums around the world, near-operational submarines are a little less common.

Long, hard, black… however now devoid of any seamen.

The little access hut looks a bit out of place compared with the sleek design of the rest of the machine.

Various snorkels and periscopes.

If you’re looking for some less recent history, the museum also has two large wooden ships –  replica of the endeavor as well as a restored tallship.

A clone of the ship HMS Endevour, used by James Cook for Britain’s “discovery” of New Zealand, Australia and other pacific locations.

I might have found something even more uncomfortable than economy class for traveling around the world on…

Some excellent views of Darling Harbor

Pyrmont bridge and Darling Harbor

If you have several hours to spare in Sydney, the museum is well worth a visit, especially if you love complex machines such as warships.

Debian Testing with Cinnamon

I’ve been running Debian Stable on my laptop for about 10 months for a number of reasons, but in particular as a way of staying away from GNOME 3 for a while longer.

GNOME 3 is one of those divisive topics in the Linux community, people tend to either love it or hate it – for me personally I find the changes it’s introduced impact my workflow negatively, however if I was less of a power user or running Linux on a tablet, I can see the appeal of the way GNOME 3 is designed.

Since GNOME 3 was released, there have been a few new options that have arisen for users craving the more traditional desktop environment offered – two of the popular options are Cinnamon and MATE.

MATE is a fork of GNOME 2, so duplicates all the old libraries and applications, where as Cinnamon is an alternative GNOME Shell, which means that it uses the GNOME 3 libraries and applications.

I’m actually a fan of a lot of the software made by the GNOME project, so I decided to go down the Cinnamon path as it would give me useful features from GNOME 3 such as the latest widgets for bluetooth, audio, power management and lock screens, whilst still providing the traditional window management and menus that I like.

As I was currently on Debian Stable, I upgraded to Debian Testing which provided the required GNOME 3 packages, and then installed Cinnamon from source – pretty easy since there’s only two packages and as they’ve already packaged for Debian, just a dpkg-buildpackage to get installable packages for my laptop.

So far I’m pretty happy with it, I’m able to retain my top & bottom menu bar setup and all my favorite GNOME applets and tray features, but also take advantages of a few nice UI enhancements that Cinnamon has added.

All the traditional features we know and love.

One of the most important features for me was a functional workspace system that allows me to setup my 8 different workspaces that I use for each task. Cinnamon *mostly* delivers on this – it correctly handles CTL+ALT+LEFT/RIGHT to switch between workspaces, it provides a taskbar workspace switcher applet and it lets me set whatever number of workspaces I want to have.

Unfortunately it does seem to have a bug/limitation where the workspace switcher doesn’t display mini icons showing what windows are open on which workspace, something I often use for going “which workspace did I open project blah on?”. I also found that I had to first add the 8 workspaces I wanted by using CTL+ALT+UP and clicking the + icon, otherwise it defaulted to the annoying dynamic “create more workspaces as you need them” behavior.

On the plus side, it does offer up a few shinier features such as the graphical workspace switcher that can be opened with CTL+ALT+UP and the window browser which can be opened with CTL+ATL+DOWN.

You can never have too many workspaces! If you’re similarly anal-retentive as me you can go and name each workspace as well.

There’s also a few handy new applets that may appeal to some, such as the multi-workspace window list, allowing you to select any open window across any workspace.

Window applet dropdown, with Nautilus file manager off to the left.

I use Rhythmbox for music playback – I’m not a huge fan of the application, mostly since it doesn’t cope well with playing content off network shares over WAN links, but it does have a nice simple UI and good integration into Cinnamon:

Break out the tweed jackets and moleskins, you can play your folk rock in glorious GTK-3 graphics.

The standard Cinnamon theme is pretty decent, but I do find it has an overabundance of gray, something that is quite noticeable when using a window heavy application such as Evolution.

Didn’t you get the memo? Gray is in this year!

Of course there are a lot of other themes available so if the grayness gets to you, there are other options. You also have the usual options to change the window border styles, it’s something I might do personally since I’m finding that the chunky window headings are wasting a bit of my laptop’s very limited screen real estate.

Overall I’m pretty happy with Cinnamon and plan to keep using it for the foreseeable future on this laptop – if you’re unhappy with GNOME 3 and preferred the older environment, I recommend taking a look at it.

I’ve been using it on a laptop with a pretty basic Intel GPU (using i810 driver) and had no issue with any of the accelerated graphics, everything feels pretty snappy –  there is also a 2D Cinnamon option at login if your system won’t do 3D under any circumstance.
