All of the above data warehouses have good support.
You can use almost any popular BI tool with all of them. All of the above have ODBC/JDBC drivers that BI tools can use. And since these are the most popular data warehouses out there, most BI tools implement their connectors.
That's actually a challenge that we tried to overcome - being able to get the big picture on the one hand, while still being able to catch and filter a single event.
You might want to dig in and truly understand what a "3 star" establishment is and the insane amount of hard work necessary to achieve it. The trick to earning any kind of Michelin Star, even one, is to keep the diner from ever seeing that work.
It may seem "amazing and enriching" from the outside, and sous-chefs that work in these establishments surely have a resume that will open doors around the world, but to think it's a fun or entertaining experience is an incorrect assessment.
Likewise, while I haven't worked in a CMMI-5 environment, I have worked in an organization where I was required to be trained in TSP/PSP which (arguably) provides an even lower defect rate than CMMI-5. The amount of process and paperwork required was absolutely ridiculous and eventually caused me to leave due to all the fun simply having been removed from the job.
It may produce high-quality output, but you won't enjoy doing it!
I wasn't talking about the awards specifically, but rather about the state of mind. And I'm sure working in such a restaurant is not for everyone. But it's nice to see people who actually enjoy the challenge.
Are there companies that take quality, perfectionism, innovation, workmanship to that level in the tech industry? And do they succeed more than other companies?
I still don't think that a blockchain is really the answer though. It's an answer to Zooko's Triangle, but it also removes an element of privacy.
Do we need global names? I just want to talk to my brother, my friend, my colleague; I don't really care about talking to people I don't know. Given that, what's wrong with identifying people as 'Billy's wife's mother'?
What are you thinking of specifically? The chain wouldn't contain any network of contacts (like GPG signatures) and only hashed information about the user.
Worst case is that a user's number of devices and public keys can be looked up.
> The chain wouldn't contain any network of contacts (like GPG signatures) and only hashed information about the user.
If 'hashed user information' means a function of the user's identifier (e.g. the user's email address, or some other global user ID), then privacy is lost because one could hash any user's ID and see what his public keys are; many protocols include an identifier for the sender's public key in order to guide the receiver, and vice-versa. This means that one could see what messages that user has sent or received.
If it doesn't contain some function of the user's identifier, then what would be stored exactly, and what would its utility be? If I can't consult the global blockchain asking, 'what is the key for smith@example.invalid?' then why have a global blockchain? If it's simply a record where key X says key Y is the same as key X, then key Y says no it's not, then key X says yes it is again … what's the value?
Blockchains are an amazing innovation for achieving global agreement. Because of this, they can be used to bind easy-to-remember petnames (like 'bill' or 'Bill Gates') securely, such that the entire world knows that BLOCKCHAIN('Bill Gates') is the founder of Microsoft, not his father or some random fellow. If you're not using a blockchain for global agreement, what's the point?
Yes, it's supposed to be a hash of the user's identifier.
The goal is of course being able to look up the keys of individual users based on their publicly shared identifier. This system isn't trying to hide a user's keys in any way, so I think we're simply trying to solve different things
> Yes, it's supposed to be a hash of the user's identifier.
Which is why it's a privacy issue: given someone's public identifier, I can see what his key is and how it changes over time. I can see if he has a key, which is interesting information. As I noted, I can probably monitor traffic to find messages encrypted by or to his key.
Heck, I can pregenerate many potentially-valid identifiers (e.g. [0-9az]+@[a-z][0-9az]+\.(com|net|org|edu) and look for them in the public blockchain, and use that to confirm whether the accounts are valid or not (this could be used to see if an email address is valid without ever sending email to it). I could use this to verify addresses before sending out spam or malware.
If I can see two identifiers who communicate with one another, I could use this to, say, malware purportedly from one to the other via unsigned email, who is likely to trust it because it appears to be from someone he knows.
You see the issues, I hope. This kind of thing really is tough.
