te··on Show HN: Bomberland – An AI competition to build the best Bomberman bot
Where can I view recorded or real-time matches by existing bots? Where's the leaderboard?
te··on Ask HN: What problem are you close to solving and how can we help?
Splice you parent file at the time stamps, interleave the samples, then concat.
te··on Ask HN: What problem are you close to solving and how can we help?
At the risk of not being helpful: I have some json files that are updated weekly that I keep under source control in git. The week-to-week updates are often fairly simple, but git was showing some crazy diffs that I knew were way more complicated than the update. I soon realized that the data provider was not consistently sorting the json arrays; when I began sorting the json arrays by rowid everytime before writing it, the diff's were as straightforward as expected. I think I don't understand the problem you're encountering, because this solution seems too obvious.

Lol, if only.

te··on Tesla: Recalled touchscreens were meant to only last 5-6 years
You can guesstimate the average service life of a car using Little's Law: https://en.wikipedia.org/wiki/Little%27s_law

Share of new cars was 6.9% in 2019, ~5.0% in 2020, and scrappage rate was 5.1% in 2019 (source: https://news.ihsmarkit.com/prviewer/release_only/slug/bizwir...).

If the average in/out flow per year is ~5%, average life is 20 years. If 6%, ~17 years.

Nim or Julia?
te··on Why the Apple II Didn’t Support Lowercase Letters
We had an Apple II+ with the limitations you describe. However, we purchased and installed the 80-column card that provided both 80-columns and lowercase characters, which is what I think the parent comment is suggesting.
te··on How many pieces can a puzzle have?
Who is the manufacturer? I don't think I've ever seen a non-grid jigsaw puzzle before.
te··on Remark42: Self-Hosted, Lightweight Comment Engine
HTML. Say, a blog post. Or a technical document. Instead of comment threads at the bottom, I imagine the comments inserted/attached inline in the text, perhaps only visible with mouse hover or appearing in a sidebar.
te··on Remark42: Self-Hosted, Lightweight Comment Engine
I'm seeking a library that enables inline comments and annotations within a document. Can anyone recommend something?
te··on Stock and Flow (2010)
What is the (spiritual) successor of DYNAMO? Would Modelica be a fit?

Sorry, who is Calvin? Can't find any reference.

te··on Concurrent Hash Tables: Fast and General? (2019)
I'd probably look at this one as well: https://arxiv.org/abs/1809.04339
te··on Senate Stock Watcher
Nice job, I really like this and find it useful. A couple ideas I'd love to see implemented, depending on how far you want to go with this:

(1) On the "top 5 traded tickers" display, just go ahead and list all the tickers and not just top 5. This will summarize the day-by-day info on the left panel. Would be nice to sort the traded tickers summary by either count or ticker.

(2) So right now, we can select a date and see the reports from Senators that reported that day. Additionally, I'd like to name a Senator and see all their trades across all reports in a single screen. Finally, I'd like to click (or input) a ticker and see all reported trades for a given ticker among all Senators and all dates.

Thanks again. I wasn't even aware this info was now publicly reported. A small step forward, I guess.

te··on Ask HN: Introductory Books on the Stock Market?
I was put off by the title of this book, but after reviewing the Table of Contents, I'm quite intrigued and I'll be picking up a copy. Thanks for the recommendation -- I probably wouldn't have gotten past it's title without it.

te··on Banks, Arbitrary Password Restrictions and Why They Don't Matter
Sure, three-strikes-and-out reduces probability of brute forcing any particular account with forced 5-digit password, but if an attacker has a list of just 25k usernames, odds are that at least one is going to get brute-forced.
te··on How to Always Win at Dots and Boxes (2015) [video]
While I had no name recognition of this brilliant theorist, turns out he is the same guy that wrote Winning Ways for Your Mathematical Plays (recommended). Also found this sad news: https://news.berkeley.edu/2019/04/18/elwyn-berlekamp-game-th...

What are the n most useful knots for sailors? Other outdoorspeople? Eagle scouts? All-round handy problem-solver types?
te··on The Hanabi Challenge: A New Frontier for AI Research
From the paper:

> The main difference in Hanabi is that there is no “cheap-talk” communication channel: any signalling must be done through the actions played. It is therefore more similar in spirit to learning how to relay information to partners in the bidding round of bridge.

Jakob, why did you choose Hanabi instead of bridge itself? Bridge is obviously much more widely known and seems to present similar challenges.

If someone can figure out CO2 -> C6H12O6, it's probably worth more than $1mm.
te··on Basic Income Research Proposal
> you need to guarantee them that stability forever

In that case, you're going to have to be content with a thought experiment, because there is no entity that can credibly make such a guarantee.
