So, my pettycoin talk from 6 minutes on is actually an explanation of sidechains.  If you're interested in #bitcoin and #sidechains I suggest it's the most accessible technical explanation currently available.

Plus, bonus Merkle jokes!  (Well, actually one joke repeated ad nauseum)

My linux.conf.au "Pettycoin 1.0" talk is going to be dense.  Mainly because it's about "What I should have done" which involves explaining enough of bitcoin internals to explain the sidechains paper, then going further and explain Gregory Maxwell's various proposals to scale bitcoin.

There are two big pluses to this: firstly, I haven't seen these concepts presented in easy-to-digest form before.  Secondly, attending this talk may give insight into improvements which some very bright people have proposed for bitcoin, which I thus expect to show up in sidechains in the medium term.

Where do I find (someone with access to) an original Breakout arcade machine? I want to know what the full angle for the spinner was, so I can calibrate mine.

Long version: I am introducing my daughter to video games in chronological order. We are starting with Breakout, 1976. I obtained a spinner, and am running DICE. But if she ever gets the chance to play a real one, it'd be nice if she weren't too off...

Go to scratch.mit.edu. Great programming environment for kids so you can create your own games from scratch.

I have done pong and frogger with my kids. And they have done some simple games of their own.

It is similar to programming lego mindstorms using blocks to build the logic.

Do you know someone who has made significant contributions to the Linux Australia community?  It'd be great if you could send in a few words about them for the Rusty Wrench 2015!

When I grow up, I want to be Jon.
 
So, after a fair amount of thought, I decided to toss some money into the OLS campaign (which ends on the 24th).

I had to think about it for a few reasons.  Like many people, I feel that the problems with OLS were avoidable — or at least foreseeable — and that things should not have gotten to the point they reached.  I was irritated by the initial appeal on the site, where Andrew claimed that nobody had told him that there were problems; I know that to not be the case.  It's easy to think that Andrew made his bed and can now sleep in it.

But, in the end, OLS was, for years, one of the chief gathering places for our community.  A lot of good work was done there, and a lot of fun had as well.  If we are truly a community, we can help out those among us who have run into trouble while trying to maintain a community institution.  So, I think, tossing something in is the right thing to do.

I would encourage Andrew, though, to apply the full amount that comes in against the outstanding debts and seriously reconsider any thoughts of continuing the event in the future.  It had a good run, but I think that its time has passed.
We have served the Linux Community for 15 years, but now we need some help.

Leslie's  http://hawthornlandings.org/2015/02/13/a-place-to-hang-your-hat/ #labhr post made me think of one particular contributor who I have to thank:

+Nelson Castillo has done awesome work finding bugs and reporting problems in the #pettycoin prototype.  Despite my warnings and insistence that nothing was ready, he bravely ventured in and the result of his reports and feedback was two releases which are actually vaguely usable!  His solid enthusiasm and interest are sure to take him far in whatever projects are lucky enough to attract his attention in future.

(And thanks for the great idea +Leslie Hawthorn! )

#lca2015 Looking for someone who has attended only one or two LCAs before to co-present the Newcomers session this afternoon.  Diversity is important, and I'm getting old and crabby :)  Inexperience a must!

Stewart Smith: I am with you on that one!  But maybe I am old enough to qualify as steampunk just as I am...  :-)

Spent some coding time looking at Invertable Bloom Lookup Tables, esp. as proposed to apply to transmission of #bitcoin blocks (a side effect is that there is now an invbloom #iblt #ccan module):

WTF happened while we are on holiday?
 
Freedom of the press is now but a memory.
Spy agency ASIO will be given the power to monitor the entire Australian internet and journalists' ability to write about national security will be curtailed when new legislation – expected to pass in the Senate as early as Wednesday – becomes law, academics, lawyers, the Greens party and rights groups fear.
