dsil··on Launch HN: Mozart Data (YC S20) – One-stop shop for a modern data pipeline
I have a lot of experience with this coming from a background in healthcare. We are not HIPAA compliant yet, so that might be a dealbreaker for some.

There are workarounds, eg for database connectors, and some other connectors, we let you specify which schemas/tables/columns to sync, so you can choose to not sync PII columns (or hash them), and still get a ton of value from the other data and/or aggregates.

And not for PHI, but some of our customers pull all their data into Mozart, write some data transformations within Mozart to redact sensitive data, then use role-based-access-control to give the rest of the company full access to redacted tables, and only certain people have access to the full data.

That said, the security of our customers' data is our top priority regardless of what type of data it is. We're currently in the process of being audited for SOC2 type2.

Sorry, we don't support self-hosting yet.

I should clarify, step 1 in most pipelines is pulling data out of the sources and replicating it in Snowflake. Then a multi-source join is a normal ANSI SQL join on literal tables in different schemas of the same database, not "tables".

(Some call this model "ETLT", where the first ETL part is just moving data from APIs or other databases into a shared db, and the extra "T" joining that data across sources or otherwise organizing it in useful ways.)

Thanks!

Thanks for the feedback, maybe we need to make that clearer. We do host/store the data - under the hood we're using Snowflake for warehousing, but we don't currently provide visualizations too. Once your data is organized most people hook up a BI tool, and/or export to Excel/Gsheets.

Components of this certainly already exist, we're trying to put it all together in a single platform and make this functionality easier to use.

dsil··on Bitcoin Falls Below $2,000
Maybe, or maybe not
dsil··on Buck – A build system developed and used by Facebook
It's important because a lot more gets done when multiple people are being paid to work on bugs & features full-time than when it's, say, one person trying to find some spare time in their evenings.
dsil··on An Open Letter to the Uber Board and Investors
About $25 of my dollars that would have gone to them went to Lyft instead this week.

Sounds like he is anti-abortion.

dsil··on Uber's Loss Exceeds $800M in Q3 on $1.7B in Net Revenue
Network effects are incredibly important for the service they're able to give. Where I live they have so many active drivers that I never have to wait more than 5 minutes if I request one sometime between ~8am-10pm.

And that effect is even larger for things like Uberpool, where a smaller network means they may have to go way out of the way to find another rider going to a similar destination, making your ride take longer and the service worse.

Network effect also extends to their other services, like Ubereats, where they can get you your food faster and more accurately-timed than their competitors, because of their larger network of drivers.

fyi, your cards from the 90s might be worth thousands of dollars.
dsil··on Python 3 Is Winning Library Developer Support
I really like the showing-his-work, via ipython/jupyter notebooks. Unfortunately it's behind an azureml login so it can't be directly linked.
dsil··on Porting third-party programs to TempleOS
The author of TempleOS posted to reddit/r/programming, and is commenting on it there:

dsil··on Microsoft accepting Bitcoin
Essentially the fee is split up by everyone who is running the nodes that make up the Bitcoin network. The more hash-power you have the larger your share of the fees.
dsil··on Coinbase Insured
Unless I'm misunderstanding, they're really saying they're now insured for ~3% of the BTC they hold. For security, they've always said they only store about that much online, the rest is offline cold storage, but this post says:

"Coinbase is now insured against theft and hacking in an amount that exceeds the average value of bitcoin it holds in online storage at any given time."

So you're still at the mercy of their offline storage security. Not saying there is a better option for most people, but this wouldn't protect you against a Gox-like breach.

dsil··on Gavin Andresen, the Most Powerful Person in the World of Bitcoin
That's part of being "finicky".
dsil··on Uber vs. Car Ownership
Hold on, what you're missing is the last part of the essay, the difference in value of time spent driving vs time spent riding an Uber.

Say you averaged going 45mph. Then your 9000 miles took 200 hours. And you'd spend $4000 extra to use Uber, so not having to drive would cost $20/hour.

Depends how you'd use that time, but for many it would be well worth $20/hour to be able to do other things, like bill hours.

dsil··on Computer Science: the 8th Highest Paid College Major
Almost everything above is some sort of engineering:

1) Petroleum Engineering

2) Actuarial Mathematics

3) Nuclear Engineering

4) Chemical Engineering

5) Aerospace Engineering

6) Computer Engineering

7) Electrical Engineering

(on web at least you have to click the little arrows on the sides of the images, not sure on iPad)

There's no point to doing that. He can't step down or be removed as the inventor of javascript, but he could step down or be removed as CEO of Mozilla.
