Pebble circling the drain?

Seems like the recent cuts at Pebble have cut too deep into inventory control, the website, and customer service. Alex ordered a new Time two weeks ago, charged when it shipped (+$25 for express 2-5 business day delivery), queried after 5 days, told it hasn't shipped, told it was out of stock, offered refund, had order cancelled without apology. Website still says in stock.

I'm posting this as a warning to those who backed the recent Kickstarter, who (like me 2 weeks ago) thought it was a sure thing :(

Nooooooooooo! Ever since my Pebble got screen tearing, and I switched to Wear, I keep telling myself that the next one will be Pebble once again.

Back to work on #lightning today: writing standard docs towards which I can aim my implementation. One reason progress had been slow is that you need implementation and specs to evolve somewhat on sync for best results...

TIL that typing "stop" in a terminal in #Ubuntu Unity, it will stop your window manager, prevent keyboard input from entering any window, and even if you manage to cut & paste "start", it will say something about unknown session and you'll end up switching to a VT and rebooting.

Despite reports, it seems that stuck #bitcoin transactions due to full blocks aren't real: http://rusty.ozlabs.org/?p=573

I've talked to the developers at Greenaddress.it, and they seemed extremely good.  I haven't used their wallet myself, however...

Unconfirmed transactions in bitcoin were always a gamble, but the actual failure rates for large players doing this are generally kept under wraps. Combined with the notorious slow propagation of bad news in the Bitcoin community, this has lead to a belief that with a few precautions, unconfirmed txs can be accepted with minimal losses.

Turns out, it's hard and getting harder; the recently merged opt-in replace-by-fee doesn't actually move the needle that much. But it does really help in a variable-fees world, which seems to be the future...

+Alan Cox I don't think Intel makes any other string instruction than "stos" and "movs" particularly fast. Historically "scas" had certainly been very slow.

It is small, though.

Like all prototype implementations, #bitcoin #lightning is two steps forward, one step back. So I've started a blog about what I'm doing, aiming for weekly updates: https://medium.com/@rusty_lightning
Rusty is a Linux kernel dev who wandered into Blockstream, and is currently trying to produce a prototype and spec for bitcoin lightning.

Due to personal circumstances, I will miss ‪#‎lca2016‬. And I am missing it already. This is the conference series which I kicked off last century, and it feels like an ending. But it has grown so far beyond its humble beginnings that in recent years I've tended to just wander around awestruck and a little dazed. Have a great time everyone, and be great to each other...

Dear Internet,

    I have been searching for names suitable for a male child to grow into.  Marcus was good: latin roots, ending in -us for a classic male name, even containing an oblique Babylon 5 reference.

  However, his little brother is proving more difficult.  Repeating the -us trick gave me "Calculus" and "Abacus", and neither passed the wife acceptance test.  Satoshi was also right out.

  If you have any names you actually like, please share your wisdom...

git submodules seems like a horror show.

How do you write a makefile rule which checks out the git submodule?
A: Don't.  Just.  Don't.

Let's try the obvious:

daemon/jsmn/jsmn.c::
    git submodule update daemon/jsmn/

Submodule path 'daemon/jsmn' not initialized
Maybe you want to use 'update --init'?

OK, let's use --init then?

daemon/jsmn/jsmn.c::
    git submodule update --init daemon/jsmn/

This works only once!  Seems like if you run --init twice, git insists your outer repo is dirty, which neither git reset --hard nor git checkout fixes.  So, let's try running it without --init first:

daemon/jsmn/jsmn.c::
    git submodule update daemon/jsmn/ || git submodule update --init daemon/jsmn/

This doesn't work at all, because git submodule update spits out that error and exits with status 0.

submodules also splatters metadata into your repository which means they aren't restricted to branches (try having conflicting submodules in separate git branches!), and can't be carried as patches (which, in git, is a sin of the first order).

It seems like the current Best Practice is not to use submodules?
