biggestdummy··on The 1788 Doctors' Riot
Healthcare is so corrupt that life expectancy in the US went from 40 years old in 1880 to nearly 80 years old today. What a crime! https://ourworldindata.org/life-expectancy
biggestdummy··on Some thoughts on the $660k copy of Super Mario Bros
Have you seen India this week? Michigan?

Airlines are still working at skeleton staff. Most of the country has little/no indoor restaurant seating. Sporting events are highly limited. Concerts and Conferences aren't happening - or even scheduled to happen in most cases.

The current federal Unemployment extension is thru Sept 6. Which might be a bit pessimistic, but IMO better to leave some margin for safety.

biggestdummy··on Some thoughts on the $660k copy of Super Mario Bros
We (in the US, at least) are paying able bodied people not to work, precisely in order to have them not work. The policy being that it is better for the entire society if all the laid-off service economy people (retail, hospitality, entertainment, restaurants, etc.) stay home. If we did not pay them, they would find other work, which would require them to leave home. Which would be counter to the public health policies. Staying home is the _point_ of the policy, not a side-effect.

Tons of complexity behind this, but the simple problem is source of truth. When you store data in multiple places, if they become unsynchronized, which is the true answer??? Within a monolithic system, you don't have differing clocks, network partitions that can be very weird, etc. And, a related problem, which is race conditions. What if you are reading one copy of the data while the other replica is being updated. Most complexity, imo, arises from this fundamental problem and the various techniques to deal with it.
biggestdummy··on Are there large deployments of of Cassandra or Scylladb today?
Apple, Netflix, Hulu, Uber, Instagram, Verizon, T-Mobile, AT&T, Walmart, Disney, Cisco, etc. etc. Honestly, I'd be surprised if there were a large, modern company that didn't have Scylla or Cassandra somewhere in its stack.
biggestdummy··on The Mark Cuban Cost Plus Drug Company
Yes, a tablet is a single pill. Sometimes you'll split the pill, so a tablet might be 2 doses. But 1 pill.

Note that retail pricing is an unreliable indication of actual cost to consumers. They jack it up so that they various plans can claim huge discount policies. Some of these plans are free, so there's very few people who are paying this "retail" price.

The pill makers get paid by the consumers and, in most cases, by the plan-owners. And such agreements are made exceedingly complicated. IMO, only to make them more opaque and more difficult to regulate.

Unfortunately, such a system is highly regressive as the richest tend to have the best plans, the poorest tend to have a meager plan, and the transient have no plan other than showing up at a hospital.

biggestdummy··on No One Wants Used Clothes Anymore (2018)
This is a fallacy. Most people enjoy creating/building/earning if they are given a path to doing so. Helping unfortunate, poor, disabled, and even the occasional lazy person is no vice.
biggestdummy··on The “$20M to $500M” Question: Adding Top Down Sales
I think your #1 problem is market. It seems hard to try and make money directly from the "Frugal community" - a community defined by a desire to not spend money. You don't need Sales. You need a different market (spenders) or a different revenue source (ad-driven). Or just make it an avocation. Not all things must create revenue to be valuable.
biggestdummy··on Do not sign a contract with Snowflake
I'm confused. What are you are asking for them to do?

You pre-paid for $10k of usage, with an agreement to roll-over unused credits into next year's contract. The plain definition of roll-over includes the fact that you'd have an active future account. Otherwise, they'd just say "prepay credits never expire". Imagine trying to use roll-over minutes on a phone plan where you cancelled the phone.

$1k/yr seems like a very low minimum which will serve as basis to roll your $9k of existing credits into.

Sounds to me like you just didn't think about or budget for this. Doesn't sound like any misrepresentation to me.

biggestdummy··on Ask HN: How to learn sales?
Hire someone. Or, if you don't have money, bring on a co-founder.

All the books and suggestions could make you better. But if you've never sold, there's probably a 10% chance that you'll _ever_ be good at it. And if you had an interest, you probably would have done some SA/SE work earlier in your career - given that you haven't, your chances are probably lower.

Finding a good salesperson is also no easy task. Best advice is to recruit someone who has sold you something. You have the relationship already, and you know that they are able to build trust and win business.

biggestdummy··on Oracle’s BlueKai tracks people across the web – that data spilled online
How, exactly, are the ads supposed to be targeted if data isn't being sold? How is Fiat supposed to learn that you are interested in buying a car, if there's no tracking and sale of your browsing history? Not saying that being tracked is good. Just that saying "I'm ok with targeted ads, but not ok with tracking" doesn't make a lot of sense.
biggestdummy··on Jepsen: PostgreSQL 12.3
Odd that you would point out MongoDB as your named example, as it is pretty awful at sharding/clustering. For HA, the more better example would be Cassandra or Scylla. Mongo's success is more tied to the ease of development with a native JSON document DB, rather than any claims to scalability. (Insert "Mongodb is webscale" video here.)
biggestdummy··on Scraping Recipe Websites
Among other things, I am a cookbook author, so I know a fair bit about this.

Ingredient amounts are not subject to copyright protection. Any prose - intros, descriptions, instructions are covered by copyright the same way that any other book would be. So, yes, this kind of activity is likely in violation of copyright.

Let me also say that I find it a bit insulting that people who make a living creating IP (software) would be happy to disrespect the IP of these recipe authors. By taking the recipes from outside of the revenue source (a book, a banner ad, a cookie, whatever), you are stealing from the author and the publisher.

I make 25 cents on every book that is sold. So I don't actually care if you steal from me. The money is tiny. But it is a bit insulting when people - in my own living room, reading my copy of my book - decide that they want to take a picture of a recipe instead of buying a copy. It devalues the hundreds of hours and thousands of dollars that I sunk into the creation, cooking, and photography of the book.

So here's the moral of the story. Waiters should leave good tips because they know that waiters depend on tips. And IP creators should know better than to steal IP.

biggestdummy··on DynamoDB Compatibility Layer for Apache Cassandra
Correction - ScyllaDB. https://www.scylladb.com/alternator/
biggestdummy··on Scylla Cloud: The Fastest NoSQL Database as a Managed Service
Fair notice: I work at Scylla. There's a whitepaper that compares Scylla vs Dynamo on performance, functionality and price. https://www.scylladb.com/wp-content/uploads/comp-scylladb-vs...
biggestdummy··on KeyDB: A Multithreaded Redis Fork
And Alibaba did it a couple years ago with Pedis! https://github.com/fastio/pedis (looks like the project is still active, but I don't really know of anyone else who uses it.)

biggestdummy··on Going Head-To-Head: Scylla vs. Amazon DynamoDB
Are you serious? Or is my sarcasm meter faulty?

So you solve 500 errors by provisioning 4x your usage? Seems like solving a leak in the gas tank by instructing the user to simply fill up the tank more often.

Nice business if you are the gas station!

biggestdummy··on I/O Access Methods for Linux
Yes, video streaming and management is a use case as you describe. Metadata is kept in memory, and the video files, themselves, are stored on an inexpensive media - usually as file system. So queries about "what can i watch" are quick, but loading the video can take seconds. But any use case where you want to keep state over time - sums, averages, maxes, histories - requires you to keep all the individual points of data in the database. Those are the (increasingly common) use cases that I run into where very fast disk storage like Scylla are important.
biggestdummy··on I/O Access Methods for Linux
Agreed. For certain use cases (session store, user profile store), the lower cost of memory and the relatively slow growth of data will mean that they will usually fit in memory. But, in my experience, there's a larger, and growing, class of use cases (ML, IOT, Fraud detection, Gaming data) where both the amount of raw data captured and the expectations for data retention are causing the total dataset to spiral into the dozens or hundreds of TB, with expectations for real-time SLAs on query. That's what I was talking about.
biggestdummy··on I/O Access Methods for Linux
In my experience, the amount of data many applications are expected to access is growing geometrically, while RAM costs are declining only arithmetically. There certainly are in-memory use cases, but for most use cases it is not now (and probably won't become) economical.
biggestdummy··on Paul S. Otellini has died
Disagree. Just because they are business accomplishments doesn't mean that they are without value. He likely worked incredibly hard to achieve those results. Why shouldn't they be recognized along with his mentoring and philanthropic works?
