This is just very cool.

I finally got around to play with the "AppImage" version of +Subsurface, and it really does seem to "just work".

It not only allows for a project to create a complex Linux application (in the case of subsurface, one that uses very recent library versions that many distributions don't even have available yet) that works on multiple distributions, you don't even need to really even install it. Download a file, mark it executable, and run it.

It comes with its own little embedded compressed ISO filesystem that gets mounted and contains all the required libraries.

Sure, it means that the end result is much bigger than a distro-native binary would be, but if you want a way to build applications for your users without limiting them to a particular distribution, or having to build fifteen different images, it really looks like it works very well.

I assume this is probably cleaner than building the package myself from source or using something like FPM(fucking package manager) to force the package build if I don't have enough info for the SPEC file?

Portland got one of those indoor skydiving places this week. Yay! So obviously I had to try it out immediately.

I didn't get any video of myself in the wind tunnel, but it's easy enough to visualize. Just close your eyes, and imagine seeing a flounder flopping around in a clothes dryer. You won't be far off.

So I learnt the trigonometric functions as being relationships in right-angle triangles ("sine is opposite over hypotenuse"), and have been a bit disappointed that my kids too seem to be learning that old way.

Learning sine and cosine as the movement on the unit circle would be so much more useful, I think. And explains why the signs go like they do, why radians are more "natural" than degrees etc etc.

This visualization is more of that.

Let's see how the whole FCC vs router upgrading thing turns out, but I'm happy to have been contacted by Dave Taht & co about at least trying to clarify that locking down WiFi routers isn't the answer..

It's not just that the various open router projects allow people to play with - and fix - their routers: the upgradable WiFi routers have also been instrumental in making it much easier to experiment with queuing algorithms and IPv6 etc.

Maybe someone should inform the FCC about the router botnets the stock vendors have enabled because of their faulty code.

So +Miika Turkia had some even more impressive pictures from under water.

Allegedly I was on pretty much all the same dives he was, but you'd never know it from the pictures. And I'd never actually realized that blennies (well, at least some of them) have "antlers". You basically don't see them without magnification. In Miika's case, that involved not only a macro lens but a wet diopter on top of that.
We had an enjoyable dive trip with +Dirk Hohndel and +Linus Torvalds in Bonaire. And here are my souvenirs from the trip for all to enjoy.

Shot with Olympus OM-D E-M5 and 60mm macro lens or 9-18mm wide angle. For some shots I had to use Nauticam's super macro converter to get required magnification. Lighting done by dual Inon strobes.

I'm sharing Dirk's pictures, because as usual, mine tend more to "blurry fish butt" than anything useful.

In fact, I have really given up on underwater photography, and only took my camera on one dive for comedic relief.

There were three serious photographers on the trip, all sending out their photos by email to the group at the end of the day, so I felt I had to participate to lighten the mood a bit and make everybody else feel better about themselves.
Pictures from the latest dive trip with +Linus Torvalds and +Miika Turkia (among others).
Thanks to Miika with a much stronger than usual bend towards macro photography... enjoy

And since people are always asking about this... All pictures were taken with an Olympus E-M5 and Olympus 12-50mm lens in a Nauticam housing with two Sea&Sea YS-D1 strobes.

We were diving at Divi Flamingo Bonaire +Divi Resorts with Serge and his wonderful team.

"What is this, a G+ for ants?"

The "new G+" seems to have dropped the support for more than two columns. So it's back to the bad old days of 50% gray horizontal space. Because clearly there is no better use for it.

Maybe google doesn't buy their engineers any good monitors, and so they haven't learnt about that whole 4k screen thing? But the old G+ at least gave me three columns.

Hey look. There's an actual study that says Sudafed PE is worthless junk.

Of course, you could have just asked any diver. The original Sudafed (without the "PE", and with pseudoephedrine - the one people make meth with and is thus often restricted) actually works, while the diving community knows that Sudafed PE is useless junk. Competent pharmacists I've spoken to seem to know it too.

So how about it, Johnson & Johnson - show some actual spine and remove that misleading junk from the shelves. It just makes you look bad.
Doctors and pharmacists call on the FDA to ditch phenylephrine.

"On the internet, nobody can hear you being subtle"

.. and it turns out that apparently you can replace "internet" with "stage".

So I'm back home from LinuxCon EU in Dublin, and notice that most tech news sites who reported on me being on stage took the whole "Next year is the year of the ARM laptop" at face value. 

Which is fine, but it kind of misses the whole point I was trying to make (and clearly failed at). I've been waiting for widely available ARM kernel development machines for years now, but it seems to always be "next year".

So I'm really hoping that we'll actually see a real ARM (well, preferably ARM64) machine one of these days that you can actually develop on, rather than treat just as a development target. The Rasberry PI's, Beagleboards etc are all fun, and all the cellphones and chrome books are clearly sellign well, but as a developer I feel something is still missing in the market.

I guess the journalists in the audience weren't familiar with the "The year of the <select something that never seems to happen>" meme in the Linux community.

Qualcomm and Samsung would have to develop something not destined for a phone. They seem to ignore the details about the ipad soc being a scaled iphone soc.

I'm sitting next to +Steven Rostedt​​ at the kernel developer panel (in the audience - I'll be up there tomorrow).

Steven may have picked the wrong seat for getting any pictures. At least +Greg Kroah-Hartman​​ is tall, so you can see part of him (and Julia Lawall) over the big black block in front (speaker?).

I feel vindicated in not being the only incompetent photographer around.

Just to show the difference in photography skills, here are mine. 

I tried to annotate the pictures with explanations. Because let's face it, they all need explanations.

This is why I have given up on underwater photography.

Don't be afraid of steep learning curves! There can be more to life than plowing the same rut deeper.

Today's poll is in honor of the homeopathy conference attendees tripping balls in Germany. Apparently they weren't very good at what they do, and didn't dilute their drugs enough.

So in honor of these people finally having drugs that did something, please fill in the blank:

I've been to Fish 'n fins twice now, once during off-season (June), and once during high season (November). Very professional. They clearly get very crowded during high season, but seem to successfully juggle having multiple boats out. Good diving, good people.
