Maybe a bit on the optimistic side? But exciting to consider the possibilities!
> As shown above, in 1804 each Representative represented approximately 40 thousand people. Today, the average population of congressional districts is nearly 700 thousand and growing.
> In order to restore the House to the citizenry, our total number of federal Representatives will have to be increased substantially. Achieving this goal is essential to extending the ground of public confidence in our government and ensuring the beneficent ends of its institution.

Then your hot lunch will buy you another hot lunch down the road!
The NYA happening with a few CEOs "behind closed doors", was pretty much a result of the year and a half of no progress on the safe hard fork part. Also remember the miners aren't really a fan of cheap transactions, which eats into their profits, and does fundamentally alter their ROI.
Segwit2X was originally sold as a compromise. Activate SegWit for the future since it requires software updates as you noted for the additional transaction formats, and schedule a 2X HF to help the network grow immediately.
> The big-blocker anti-segwit movement stalled work for years, politicized the Bitcoin space, and contributed to making many of the core devs be the target of harassment
I agree sadly, but unfortunately it was the same story on the reverse side. Look at the ridicule and scorn Mike Hearn and Gavin got for their big block proposals in 2015.
SegWit2x is basically the mining faction stealing the network away from the Core development group, forcing everyone in Bitcoin to switch software if they still want their transactions confirmed.
Not that I really disagree with them - as _something_ needed to happen, as demand (whether real or manufactured) has led to 100% full blocks for months, resulting in long transaction delays and high fees, and the rise of competing currencies, fracturing the market.
We will see if one side backs down before the HF, but due to both incredibly entrenched positions I think we are going over the edge.
I think that 2X will destroy a lot of confidence in Bitcoin, as it proves that the network can be stolen away to change the rules, and would be managed by a much smaller dev group.
Though, the Bitcoin network can survive as a zombie forever with just a couple miners and zero devs. So it may not 'fail' in that sense, just become very stable.
Gavin Andresen was that force in Bitcoin for years, as lead developer and chief evangelist, but now he plays a minor role; recently with big $$ in play and the big community split, not to mention the insane personal attacks, it is much harder to maintain influence.
I find that this is a good balance to keep the well-written comments that add to the discussion and deserve a second chance.
The whole idea behind an actual HSM is that you never trust any computer it is plugged into, it is designed to be impossible to retrieve the key stored in the device via any means. All signing operations are done internally in the device itself - you simply can't mess up and accidentally leak key information.
Though I can pretty much guarantee these devices are not directly posting transactions on a blockchain, the cost in CPU power and battery consumption is too high and the devices would cost way more than $6 in that case.
If there is still a server in between making the transactions, does it still make sense to invoke the "blockchain" terminology? To me that is where the hype part comes from.
Maybe using NB-IoT and a GPS, it could be plausible? Not at $6 now, but maybe $20, and assuming NB-IoT networks exist where your package is going.
No details, so it might be complete hand-wavy vaporware.
Also, rant, I am frustrated with the use of 'blockchain' for things that should be in a database. Makes me think the company is only hype and buzzword-driven.
So maybe check there for more explanation... all credit for the research and investigation goes to the article's author. It was really a good 'deep dive' into the internals of Struts to see how such a subtle bug could be turned into RCE.
Summary: Attacker sends a malformed Content-Type header on file upload, which throws an exception due to the Content-Type being unknown. But, in the exception text is the direct, unsanitized user input from the header.
There is not a specific text localization handler for struts.messages.upload.error.InvalidContentTypeException, so a generic exception handler ends up being used to process the exception. This generic handler turns out to parse the unsanitized user input as OGNL markup, running the attacker code when processing the exception text.
Some effort is made to blacklist loading other Java libraries in the text rendering context, however it was easily defeated by emptying the blacklist in the attacking code before calling the blacklisted modules.
Speaking with IBTimes UK, co-founder and CEO of CloudFlare, Matthew Prince, said that his company would not be blocking its service to websites listed, as it would mean submitting to "mob rule".
"Individuals have decided that there is content they disagree with but the right way to deal with this is to follow the established law enforcement procedures. There is no society on Earth that tolerates mob rule because the mob is fickle," Prince said.
...
"We're the plumbers of the internet," Prince said. "We make the pipes work but it's not right for us to inspect what is or isn't going through the pipes. If companies like ours or ISPs (internet service providers) start censoring there would be an uproar. It would lead us down a path of internet censors and controls akin to a country like China."
Must have been in a pretty bad mood.
Executing the Ethereum VM and smart contracts on the Bitcoin blockchain...
You can treat Bitcoin the same way you treat USD, there are a lot of places that accept BTC directly. Phone apps make transactions easy.
