Ask HN: What is the best DB for versioned time series?
6 by sambucini | 1 comments on Hacker News.
Dear all, time series DBs are a hot topic these days but given the focus on IoT -- or more generally measurement data -- the underlying data model typically assumes that for one time series there is only one data point per period of time, so it's really just one dimensional. However, if you work for example with forecast data (say for a stock price) you might wanna store every version of a forecast and not overwrite the previous forecast. What are in your experience the best time series databases that (natively) support two or more dimensions and also allowing queries on these other dimensions like "get forecast for delivery-time from x to y where forecast_time = z"? Thanks! sambucini

New top story on Hacker News: Real talk with a Blockchain Engineer
Real talk with a Blockchain Engineer
19 by stackzero | 6 comments on Hacker News.
I often hear these things touted by blockchain advocates: data ownership, supply chain, and "cutting out the middleman" I want to debunk these statements once and for all. Myth #1 Blockchain changes data ownership, giving power back to the consumer Anyone who becomes privy to some data has some ownership of it. Blockchain doesn't change that. If you want to share something with only a few select people you need inherent trust or an NDA. Myth #2 Blockchain can revolutionize supply chain Its a datastore with some cryptographic identity checks and tamper proof guarantees. It can't prove that a package made it from A to B or that it stayed at some ambient temperature IRL. It only records that someone attested to that, not whether its true. An ordinary database will do for an audit trail. Myth #3 It cuts out the Middleman You dont need blockchain to cut the middleman out of indusrty X. Any service trying to do this wants to be the new middleman with lower service fees cos' blockchain! Here are some axioms which I think will drive future blockchain use cases 1. The transfer of value must occur on the chain This is why digital currency is the #1 use case. We're already accustomed to digital value transfers when we use modern banking, the transfer of value is a few digits on our screens. 2. If you can't do 1) then it must be enforcable off-chain Take for example buying a house. I sign some papers at the bank and some more with an agent and then we all agree I own a house and owe the bank some money. We sign the papers because then its enforcable by law. Keyword "enforcable". If the legal system agrees a cryptographic signature on a digital record achieves this purpose then its as good as the paperwork. We're a few years away from proper legal recognition of smart contracts. Ricardian contracts seem to be a step in the right direction. Thanks for reading and hope it clears things up.

I have been using golang at work and personally for more than 2 years now. A problem i faced when I started and the problem new gophers even today is how to structure the project. Most (if not all) golang tutorials seem to be very simple and do not describe how to structure a large application. Following project is an attempt to Showcase a manageable project layout for services in golang. https://ift.tt/2zvGy73 This project is far from complete. Would like to hear some feedback from the community before continuing on this.
