LittlePeter··on Show HN: Sabre – The bullshit-free (c) programming language
In my opinion, let num = 10 is not bullshit free, num = 10 is.
LittlePeter··on The Hazards of Asset Allocation in a Late-Stage Major Bubble
Or another one: sushi swap.

Perhaps this should be a measure of a bubble too: when you ran out of names and you start using food to name financial contracts.

LittlePeter··on Bitcoin and Pollution – The Definitive Answer
Is anyone else bothered by "The Definitive Answer" in the title? It implies the author presents irrefutable argument and if you don't agree then you're wrong, by definition.
LittlePeter··on The Downside to Life in a Supertall Tower: Leaks, Creaks, Breaks
Isn't suffering? That person had to stand in the elevator between steel plates and plywood!
LittlePeter··on Green hackers around the world, let’s destroy Bitcoin
Your argument is not even an argument, it's just: "In my opinion Bitcoin has value and porn does not".

For the same reason Bitcoin has value, you could argue porn has value.

At the very basic level, if someone is paying for it, who are you to decide it has no value to that person?

LittlePeter··on I told a cat food company how much they’d save by using taller cans (2020)
I had to Google, and I think this is what is meant with "Torvald's C++ response": http://harmful.cat-v.org/software/c++/linus
LittlePeter··on Pipenv: Python Dev Workflow for Humans
I thought `pip freeze > requirements.txt` would give you a list of all dependecies, even indirect ones. Am I missing something?
LittlePeter··on The reason Wall Street is terrified of the GME situation
> I think the hedge funds, clearing houses, and DTC executed a coordinated effort to put Game Stop out of business by conspiring to create a gargantuan number of counterfeit shares of GME, possibly 100-200% or more of the shares originally issued by Game Stop.

It would take more paragraphs of text to rebuke this crackpot conspiracy...

LittlePeter··on Statement of SEC Regarding Recent Market Volatility
It's something at least. You have to give SEC some time to investigate.

LittlePeter··on AOC calls out Robinhood for blocking GameStop, suggests holding a hearing
I find AOC actually refreshingly principled.
LittlePeter··on High-flying Reddit stocks whipsaw as platforms like Robinhood curb trading
in fact, I'd like a cronjob for that. we can't be reviewing only after something major happens.
LittlePeter··on Robinhood now has a 1-Star rating on the Google Play Store
There are 67.5m GME shares outstanding. So yeah, 300m+ people competing to own single share would drive GME up.
LittlePeter··on Robinhood, Trading 212 and others go down amid AMC and GameStop stock frenzy
The matching of orders for a single asset happens on one machine, call it matching engine. Matching is done based on price-time priority. Price is set by the trader, the time is set to the time the order was received by one of the order gateways sitting in front of the matching engine.

The order gateways' clocks are in sync, up to precision epsilon. So if you send two orders serially from same data center (to ignore effects of public Internet latencies and routing), and if they happen to be processed by different gateways, you still will see same ordering of your orders in matching engine, bar some cosmic ray events.

It is all commodity hardware running some flavor of Linux.

However this was couple years ago, they may be using ASICs and FPGAs now. The matching of orders for a single asset must still be done in single process otherwise you cannot guarantee price-time priority.

LittlePeter··on Firefox 85 cracks down on supercookies
What is exactly better? I am using FF and browse Google websites, but never noticed anything.

LittlePeter··on Bitcoin Core Lead Maintainer Steps Back, Encourages Decentralization
> Since we are inevitable heading over to a climate catastrophe it's really the time to advocate against bitcoin.

I would advocate for renewable energy. It's not like miners demand electricity to be from fossil fuels. The electricity gets paid for, how you use it is up to you.

If Bitcoin would run 100% on solar power I guess then it would be fine? Or maybe you're unhappy with Bitcoin because of its goal and not the means it gets there? That would be different discussion.

It feels like people want to argue against Bitcoin, don't have credible arguments, and bring out the climate card.

Climate is going to shit, but not because of Bitcoin.

LittlePeter··on Loon’s final flight
Was 9 years really needed to come to the conclusion that

> But in the end, it was just a fundamentally flawed idea. Satellites don't pop and fall out of the sky. Balloons do, frequently.

LittlePeter··on Novichok Nerve Agent Poisoning
I think when you have so many FSB agents it is hard to maintain the quality.

See for example here, where a bunch of FSB agent graduates decided to celebrate in the open: https://edition.cnn.com/2016/07/11/world/geliki-russia-fsb-j...

LittlePeter··on Ask HN: What companies are you excited about?
I on the other hand passionately hate Notion because of the terrible UX.
LittlePeter··on Ask HN: What companies are you excited about?
The GPT-3 result were jaw-dropping, until you realize that they have mostly been cherry picked out of multiple series of generated garbage.

But even if GPT-3 is good at text generation, what are practical applications of it except generating blog spam?

For a more hype-free review of GPT-3 I suggest: https://news.ycombinator.com/item?id=24907318

LittlePeter··on The Bit Short: Inside Crypto’s Doomsday Machine
> Why on Earth would $100 billion worth of Tether rushing for a conversion into anything else drag _down_ the price of BTC? Or any other coin for that matter?

Price in which terms? USD? USDT?

Suppose it turns out tether is a fraud. What will happen? Tether holders will try to sell it for USD or Bitcoin. High supply of tether will lead to higher BTC/USDT and higher USD/USDT rate. Those who managed to convert tether to BTC will likely try to convert BTC into USD. This will lead to relative over-supply of BTC versus USD and BTC/USD will decrease.

LittlePeter··on Licensing changes to Elasticsearch and Kibana
What does it mean for Elasticsearch Service on AWS?
LittlePeter··on Great Expectations: data testing, documentation, and profiling
Some of those terrible databases are Redshift, SQLite, Elasticsearch. Redshift does not enforce unique constraint, SQLite does not have datetime.

Sure a trigger can be used. But they can also be disabled. So you end up verifying all data has been inserted using the trigger anyway.

LittlePeter··on The neural network of the Stockfish chess engine
Leela played stockfish 200 games and won with 106 - 94 [1]. Not sure which version of stockfish was used.

Some of the Leela-Stockfish games are analyzed by agadmator on YouTube [2].

LittlePeter··on Over 73% of U.S. Adults Overweight or Obese
> but noone wants to talk about it as it directly threatens various established interests.

There are many people talking about it. Adhering to healthy life style is difficult for many people. Most obese know perfectly well why they are obese an what it takes to be healthy.

LittlePeter··on Predictions Scorecard, 2021 January 01
Scott Galloway's predictions for 2021 and review of 2020 predictions: https://www.youtube.com/watch?v=umUmrzounFI

I thought the content was good, though the constant yelling is a turn off.

LittlePeter··on Baleen Analytics
The author says that the difference between ETL and ELT is that ETL extracts data from a system with well-established schema while ELT can handle schemaless data.

I thought the difference between ETL and ELT was that ETL does the transformations outside the system where the data is eventually loaded, while ELT does the transformations inside the system where the data is loaded. It has nothing to do with whether the data has a schema or not. An ETL process can work perfectly with schemaless data.

I also found the language of the author to be a bit abstract with few examples. I could not understand some paragraphs.

Then there is this unnecessary comparison with the whales.

The author also self-cites their 4 other articles.

Overall I did not like the article.
