I actually think Linus has had some of his rough edges smoothed out over the years. This was not nearly as combative as it could have been or may have been in the past!
Finite Automata and the Theory of Computation.

Lots of Turing Machines and constructing proofs. I'm not sure I would have passed if it wasn't for my friend who worked with me on the homework.

Re:Is AI the Next Crypto? Insights from 2M HN Comments on Wednesday November 08, 2023 @05:09PM (#38197829)
My private hypothesis here is that we're doing a better job as a society of encouraging "disconnection" from being "always online," which is documented to aggravate mental health issues[0].

It stands to reason therefore that the people who remain online to comment may have lower levels of mental hygiene by virtue of their ongoing exposure to the internet and social media, thus resulting in a gradual decrease in sentiment over time.

I made a safe-to-wake light for my son out of a Raspberry Pi. It serves up a responsive website on the local network so you can manually change the lights or update the schedule.

Been running like a champ for over 3 years now, which has been the most pleasant surprise. I'm used to ecosystem entropy causing things to break.

Re:Ask HN: How's the job hunt going? (For those laid off) on Tuesday November 29, 2022 @12:58PM (#33790866)
Sure!

For the first job, I bill hourly for the time I spend working. Here, I develop web applications to validate machine learning models for a company; I help organize results in a way that allows ML engineers to easily "spot check" the results of ML runs on data through a web interface.

The second job I have is in the "web3" space developing applications that run on a specific blockchain in which I've specialized. Compensation here is based on milestones and paid out in cryptocurrency.

In both cases, I am transparent about the progress I'm making and compensated accordingly. The hourly rate I charge as a contractor brings in an equivalent salary to what I had as a full-time employee in about 900 hours per year, which works out to be about 18/hours per week if you assume 2 weeks off.

Re:Ask HN: How's the job hunt going? (For those laid off) on Saturday November 26, 2022 @04:34PM (#33757003)
I transitioned from full-time employment to contracting in April 2022. I am currently over-employed and working two gigs simultaneously.

All leads have come from my personal network or my reputation as a known entity in a relatively niche field.

Only trouble I've had is invoice approval and waiting for money to be moved, but it has always eventually come through.

Cashflow remains equivalent to when I was an FTE, but I'm working fewer hours per day and working on more interesting things. A lot of that has to do with transitioning out of management, I think. I don't miss it :)

It took learning another language (Japanese) for me to finally make sense of my native language (English)'s grammar.

I still remember the day I learned the difference between transitive and intransitive verbs in Japanese and had that "ooooHHHHHH" moment in my head where all verbs everywhere finally made sense.

What a luxury to work at a place where tickets are defined and work is scoped out for you :)

If you're chafing there due to the lack of autonomy, I promise there are places hiring people whose strong suit is tackling ambiguity in addition to software development.

Are there any copyright concerns around doing this kind of thing? Surely SEGA will come after him for providing this as a free download?
Re:Create ad-hoc ClojureScript scripts on Node.js with nbb on Monday September 20, 2021 @04:06PM (#28598280)
This is like saying "you can't really leverage Java well without knowing JVM bytecode." Which is to say: I also disagree with you :)
Re:Create ad-hoc ClojureScript scripts on Node.js with nbb on Monday September 20, 2021 @01:15PM (#28596167)
I think the real advantage is scripting with a REPL in your IDE. Whipping up a script becomes trivial because you can test every data transformation (heck, every expression!) with a keystroke. There's no great way to do this in a language without s-expressions.
Re:Global deforestation peaked in the 1980s on Tuesday August 17, 2021 @06:25PM (#28215515)
I wonder how much of this changed due to public sentiment driven by pop culture? Movies like Fern Gully[0] and TV shows like Captain Planet[1] definitely had a hand in shaping my generation growing up.

Maybe not once you consider the R&D costs of figuring out how not to melt a solid gold Merlin engine ;)

BlackSky | Remote ;; Seattle, WA ;; Herndon, VA | Full Time | US Citizen

BlackSky is building the premier global intelligence platform. Our Platform delivers timely, relevant, and actionable information allowing our customers to make swift and informed decisions. In other words: we launch satellites and set up AI/ML pipelines on the torrent of data they send down. It's really cool.

You can see our business plans over at this SEC filing: https://www.sec.gov/Archives/edgar/data/1753539/000119312521...

We're especially looking to staff up our Platform team, which is responsible for building the software that delivers the data and insights our customers need. We have open positions for front-end, back-end, and full-stack developers; our language stack includes Java / Python on the back-end, and JavaScript (React) on the front-end.

We're a fully distributed team; the company is just over 150 people now, and we've got teammates in over 20 states. 100% Remote is 100% OK. Due to ITAR requirements, we are only hiring US citizens at this time.

Re:DoorDash removing 1-year cliff for equity grants on Wednesday July 07, 2021 @05:06PM (#27765730)
Typically, there's a "cliff" after the first year, at which point it switches to quarterly.

So you get nothing the first three quarters, but after quarter 4 (your first year at the company), 25% of your 4-year grant is immediately vested. Every quarter after that is another 6.25% of your initial grant.

I believe the point they were trying to make in the article is that, instead of quarterly grants following the pattern of:

    [0%, 0%, 0%, 25%, 6.25%, 6.25%, ...]

It would instead follow the pattern:

    [6.25%, 6.25%, 6.25%, 6.25%, 6.25%, ...]
```

I'm not sure I would classify that as "talking plainly." Words like that would put anybody on the defensive, and being on the defensive does not make people receptive to positive change.
Thanks for pointing that out -- I've updated the title :)
Do you think it's worth editing the title? Will I step on any metaphorical landmines because the HN community (for example) prefers immutability?

They linked a study from a medical journal. Are you asking for additional qualifications? Should there be restrictions on who is allowed to share scholarly articles?

How are things in PR these days? I can't imagine what it must be like to deal with a pandemic while simultaneously trying to rebuild basic infrastructure.

Have you been able to get back to some semblance of normalcy yet?

Ask HN: How much credit do you take for your accomplishments?

Something I've been struggling with recently is knowing how much credit I should be taking for my accomplishments.I would consider myself very successful by the measures that are important to me: great at my job, in a happy marriage, couple years away from financial independence... but I feel as though I can't take credit for these kinds of things, because I grew up a white male in a...

I believe this is less about hearing opinions and more about celebrating the next generation of hackers.

This is a fine example of a kid who has a strong opinion and, rather than shout it into their echo chamber on social media, they've taken the liberty of securing a domain name and creating a website capable of reaching a larger audience.

We here on Hacker News enjoy celebrating the initiative, the creative process, and the execution. Of course you'll find a wide range of opinions, but I think you'll find (and you imply as much by your question!) that most people on HN are happy to celebrate a the accomplishments of the next generation.

Thanks for taking the time to share, this feels like a good approach!
Re:No one gives a shit what programming language you use on Monday March 29, 2021 @09:59AM (#26621643)
The author of this post appears to do an excellent job of projecting negative emotions onto the tweet that broke the camel's back, so to speak.

He makes it appear as though the entire software development industry, and especially how developers carry themselves within it, is not to his liking. I think he is calling for more humility, but I'm not sure, because this appears to be more of an attack on a vaguely-defined group of people rather than a call to action or a proposal for how software developers could present themselves more to his liking.

Re:Japanese typography: Kilograms of sinograms on Thursday March 25, 2021 @11:25AM (#26581408)
> It is hard for me to read a text that is set only in hiragana (as in the Japanese version of Animal crossing on Switch for example, the characters only speaks in kana, with no spacing separating words...

I'm very curious as to why Nintendo made this choice!

Is it because the game is designed to be welcoming to children? In which case, why not use furigana and use it as an opportunity to learn Kanji though repetition?

Is it supposed to reflect the simplicity of a back-to-nature lifestyle and the characters therein?

I'm inclined to suspect is the latter of the two; especially if kana is only employed in character speech while other parts of the game use Kanji.

Has anybody played the Japanese version? Can you speak to the use of Kanji in the game?
