I’ve encountered an interesting bug in Autopano Giga (APG), a product from Kolor, as subsidiary of GoPro.

The Symptom:

Whenever APG is running, it constantly triggers the Mac wifi control software airportd to actively scan for available WIFI networks.

This happens when the system is connected via Ethernet, and not even using WIFI for its network traffic.

This happens despite options to send analytics, and check for beta versions being disabled.

Below, is 10 seconds of captured logfile from OS X’s wifi.log, covering launch, and then immediate quit.

287 lines of logfile in 10 seconds, and that rate continues for as long as the software is running. Once again, this machine is not using WIFI for any actual network traffic, and APG isn’t transmitting any data over this – it’s merely waking up the WIFI system, and telling it to scan the local basestations, and then writing a massive amount of data to multiple logfiles. God only knows what this would do to the battery life on a portable.

Turning off WIFI is the only way to make it stop.

The Cause:

Kolor’s official twitter account suggested to me that this is caused by APG looking for updates.

• Where’s the setting to turn off checking for updates? I’ve turned off checking for beta versions, that makes no difference.
• APG attempts to connect to google on quit, which you would only know if you had Little Snitch installed and telling you what apps are trying to phone home behind your back.
• If it is an update check, why is APG looking for updates, every (approximately) 5 seconds as long as it is running?
• Why is it powering up the WIFI scan, when the system is set to use Ethernet as its network?

The Horror:

Didn’t really get much of a feeling for the ferocity of the storm that hit last night, the tail end of Tropical Cyclone Debbie, but going for a wander down to the river this afternoon, and clearly, we copped a fair wallop.

Once upon a time, in the near future, things were going well for software codemonkey & Machine Intelligence researcher Eddie Cartridge – gainfully employed, happy relationship, and a bright future ahead.

Unfortunately, he made the mistake of coming to the attention of a particularly unpleasant piece of software. Now, he’s an internationally wanted man, paralysed after a disastrous misstep with a neuro-enhancing hallucinogen known as The Deathline, and some shady characters are dragging him down a dark corridor, towards a blindingly bright room.

Meanwhile, his former partner is rediscovering her taste for the rush of The ‘Line, while introducing mortality to a great many Machine Intelligences at her employer, in pursuit of an answer to the question “Where’s Eddie?”.

This is the conclusion to Surfing The Deathline.

Somewhat delayed, but Here’s a reflection on 2016. It’s been a relatively quiet year, mostly spent on nagging health issues. Lots of physio rebuilding my knee, which periodically gets worse, in my opinion, because the post-operative rehab physio in 2012 got me jumping too early. Just as that was coming good, I managed to tear a ligament in my dominant hand, one that keeps the tendon centred over the top of the first knuckle, meaning it fell off to the side when I bent my finger down enough. A pretty terrifying experience all round, but after 2 months in a splint it’s slowly getting better.

In terms of art, the beginning of the year saw Surfing The Deathline – Fourth Dose released, and now at the beginning of 2017, Fifth Dose is out, which means it’s all done – I could be hit by a bus tomorrow, and the work is more or less what I intended. Finishing a project that’s been going for 14 years is interesting. It didn’t really have the commercial success I would have liked, but at least it’s done. Most importantly, I’m now free to look to new projects.

Some other notable events this year were a small retrospective of student sculptures at a laneways festival, and delivering a PetchaKucha talk about The Metaning at Nambour.

Going in to 2017, what are my goals? Right now, I’m going back through the old issues of Surfing The Deathine, and updating them to the style of the last part. Then? I’ve got a bunch of photographic projects planned, some will require space to set up lights etc, some are landscape based. Along with that, there’s sculpture – I’m going to need space to weld, after which I’m going to try to learn TIG welding properly, so I can do fine and neat work. Things to look at sculpturally are revisiting the ethernet figurative piece, even if it means I just have to buy bulk cable in various shades of blue. I’ve also got to get serious about investigating bending perspex rod without blistering it, so I can build small versions of my valve sculptures.

I think that’s enough to have on my plate for the moment.

Shooting at a Brisbane cat adoption organisation. Lesson learned – use a higher minimum shutter speed for auto-iso, or use shutter priority, and trust that the indoor conditions will stop the lens up to 2.8, which is the depth of field I was using for a lot of shots.

Cats can give some pretty arresting portraits, when they’re not attempting to crash their faces into the lens.

The anachronism of using wood to create a case for a technological item, is perhaps blunted by the use of kevlar in the laminate. It provides scratch protection when placing the phone up or down on a flat surface, especially for the camera lens. A big plus is the minimalist logo on the back – too many cases have the casemaker’s name in huge letters.

While the packaging states it’s for the iPhone 5/5s, it’s also fine with the SE.
