After several months of discussion and work, we created a rating criteria for Bitcoin wallets to measure their effectiveness at protecting user privacy. Our criteria considers user protections on the blockchain, protections when receiving balance information and broadcasting signed transactions,

Creating the framework was the hardest part, and I think the most valuable.

+Justus Ranvier  I get that. But what It would still need other extra incentives is to spark a change that leads to that faster. I know you get what I mean.

Bitcoin's block size is determined by the economics of mining. Increasing the block size limit does not reduce Bitcoin's security.

I've never liked that Mircea Popescu and he's always got a mouthful of abuse for me when our paths cross.  He even accused me once of being a party in the GLBSE's demise and claimed I profited in it.  By stealing users funds just because I tried to say a few words in Nerfario's defense at the time.

Has something changed within the last 6-12 months about how bind mounts work?

Something I've done commonly is use /etc/fstab entries equivalent to:

mount -o bind / /mnt/root

This let me see the root device as in /mnt/root exactly as as it appears before anything else is mounted, "underneath" any additional filesystems.

This doesn't work any more.

I don't know exactly when this changed, but what I see now is that the behavior I get from specifying -o bind is the behavior previously obtained from -o rbind. It's like -o bind and -o rbind now do exactly the same thing.

Have you updated your Distro to one that uses systemd?
Systemd will parse the fstab for mounts, and sort the paths in a topological order, so that services which declare file paths they depend on can be started in-parallel with the file system mounts.
Possibly systemd decided that your bind-mount depended on everything else being mounted, so reordered it to be later.

Is it possible for a single decentralized blockchain to scale to a billion daily users?

yes, its accounted for due to the implementation of the decimal system that enables a bitcoin to be split in to (the satoshi) :-) one could argue the only question remaining is do people want to take part in it regardless of marketing efforts :-D
 I still own bitcoinengland.com and a few others and interest has slowed alot these days.
 Gox, BFL, china and the hackers have all give bad cred to the system and have set a corruption level before people have even had chance to get on board...
 but who knows...lets see what Greece gets up to :-D and lets be fair the way the wealth is flowing to the top of society, it may be the lesser of the two evils before long :-p

I need an initramfs to bring up my dmcrypt + mdraid + lvm root device.

I switched from a hand-rolled initramfs to dracut a few years ago.

Ever since dracut started using systemd, I haven't been able to build a new initramfs (about a year ago).

Fortunately I use monolithic kernels so I can keep reusing the same image, but the inability to create new initramfs images is starting to bite me, and I do not want to go back to making my own.

The problem I am running into is that even though systemd is bringing up all the requisite devices (verified by using rdbreak=pre-mount and checking to see that every luks device is active, the mdraids are assembled, and the logical volumes appear in /dev/mapper/), for some reason the start jobs for those tasks time out as if they didn't actually complete successfully.

I've spent most of Sunday searching for a solution to this problem and I found about a dozen mentions of this and similar problems over the last two years, but no conclusive solutions.

* I do not have a userspace firmware helper path configured into my kernel
* I do have dm_uevent enabled in the kernel
* I have lvmetad=1 in lvm.conf

My experience with systemd since the udev merge (both as part of dracut and in attempts to use as init) on four different Gentoo systems is a 0% success rate with regards to successfully using dm/md/lvm devices.

I know those kinds of devices work on Fedora systems, so it's not like systemd is inherently incapable of dealing with them, but what's the magic incantation I'm missing that will let systemd realize that the devices it's waiting on have actually started?

+Justus Ranvier I'm confused. You say that you don't store bitcoins on Coinbase, but you do interact with them (not clear why you would have to if not storing coins there). Also, if you didn't respond to them, then how do you know some kind of weird activity isn't happening without your knowledge using your account?

I'm not trying to defend them really, but just want to make things more clear. If you really weren't doing a lot of transactions through Coinbase, then why the email?

Coinbase is definitely more like a bank than anything else, but is usefully for purchasing some bitcoins and then transferring those to a regular wallet, and they are getting some large merchants to accept bitcoin, so that is very good for the community

I one made the mistake of assuming this store sold food, which I thought would be a reasonable assumption considering that it's called a Food Store. What this place actually sells is "food": synthetic food-like substances packaged in plastic and made from petroleum products, cellulose, and HFCS. If you want some actual food you need to drive a bit further to the HEB up the street.
