I think it is always egregious, regardless of whether it happens all the time or not. For example, the USG is known to meddle with other countries elections. I don't think that's excusable. I assume the RNC played all kinds of tricks as well and that this is SOP for both parties. Wrong in every case.

You appear to be thinking of the CPA requirement which is for accountants, not actuaries. I'm an actuary, and the education requirements are thin https://www.soa.org/Education/Exam-Req/edu-vee.aspx.

You could theoretically get certified with only high school and work experience, although I don't think any employers would hire someone without a bachelor's. The degree can really be in anything though as long as you've passed an exam or two, as this shows an employer that you're serious and have learned at least something.

I believe the system works in our case because there is an ecosystem of employers, employees, recruiters, and government agencies that all buy into the exam process. It's sort of a throwback guild system that's not very similar to IT certifications such as CCNA.

I'm assuming you are ok with an association with cypherpunks / crypto-anarchy, because one certainly exists even if newcomers would rather relegate these roots to history. Hal Finney was a cypherpunk and bitcoin wouldn't be possible without his RPOW system. Wei Dai, who was cited in the original bitcoin whitepaper, was also a cypherpunk, and praised Tim May's crypto-anarchist manifesto. The list goes on...

There really was no "traditional approach" to creating a distributed digital currency at the time. The blockchain is a product of Satoshi's thought and is the central innovation in bitcoin. The principal issue was not anonymity but making a network that didn't require third parties to prevent double-spending. Genuine technical problems that a lot of smart people hadn't been able to solve were solved by bitcoin.

Bittorrent was way easier because it was about copying, whereas a currency has to in a sense make copying impossible via some sort of time-stamping to prevent double-spend.

The blockchain is not just a hash tree. There's other features that mesh together in the blockchain. For example a proof-of-work system that allows bitcoin to be distributed and trust-less by preventing Sybil attacks. While using rewards for this work as the sole means of money creation was anticipated by others, the automatic means of adjusting the cost function is a Satoshi original and very important to the success of bitcoin.

I was a little surprised to see this getting traction on HN too. It would be like seeing a link to the Wayback Machine or Wolfram Alpha with no qualification.

I interpreted this to mean that your private keys are probably not as safe as you think they are.

Really like the site.

Feature request: Shortened URL so the surprise isn't given away.

Another interesting bitwise trick: flip bit 5 to swap the case of an alphabetic letter.

Just curious, why is Mongo not good enough or do you just mean as opposed to BigTable?
