karol··on Willingness to look stupid
Of course, write a book about it.
karol··on Willingness to look stupid
This is terrible advice, I would call it a lack of willingness to communicate openly. Also even if you are in the highest echelons of intelligence making yourself look stupid will close access to some opportunities that might propel you forward. Also, over time this behaviour might form a habit that will also influence your personal life.
karol··on The Nobel Prize in Chemistry 2021
It doesn't.
karol··on Lab-grown meat may never be cost-competitive enough to displace traditional meat
Most of the things you listed sound like simple, indisputable issues everyone agrees about. This is actually not the case. I suggest researching into this a bit further. There is a documentary Sacred Cow and a book Being Ecological by T Morton, which are a good start. Also this article: https://www.theguardian.com/commentisfree/2018/aug/25/vegani...

Leaving aside the truth in these claims, if the article linked in this thread demonstrates that natural processes are more energy efficient than labwork, the choice in a clean energy starved society should be very simple. I can't imagine why we need to mine the metals, build the panels or wind turbines, build the lab buildings and the equipment just to get a chunk of nutrients of questionable quality (drenched in antibiotics).

karol··on Lab-grown meat may never be cost-competitive enough to displace traditional meat
Why do we insist on growing meat in the lab, when it already grows on animal in a natural way?

It could be seen as a naïve question however I think it's a part of bigger trend where humans are trying to replace natural processes with cultural. Isn't the science-fiction dream to grow babies in an artificial womb and give them to parents "when they are ready".

This trend worries me. I think we should go the other way and acknowledge and accept that we are animals and part of the animal kingdom in every way.

karol··on Experts vs elites
Are you saying he is pontificating to be counted among the elites?
karol··on Is catching Covid now better than more vaccine?
Polio is not a coronavirus. SARS has different mutation rate, so this needs to taken into account. Additionally cats, dogs and other animals can be infected and produce unique mutations, unlike polio.
karol··on Climate change: IPCC report is 'code red for humanity'
We still cannot be sure if it is anthropocentric climate chance but that doesn't really matter. If we want to "return to baseline conditions" - what we try to show on graphs, then we need to cool down the atmosphere using aerosols: https://www.sciencedaily.com/releases/2016/05/160519120731.h...

Realistically there is not and there isn't going to be in the current decade an agreement between nations on CO2 reduction. Whatever we change in EU China and India is going to undo by mining coal. So geo-engineering negotiations should start now.

karol··on The UK’s delta surge is collapsing
Anecdotally, I never installed it for the same reason.
karol··on Paid in Full: an internet where every interaction is a financial transaction
I understand this perspective. To me your example clearly points out where neoliberalism has its limits. What strikes me is how linear this thinking is. In real life we need to receive a mixture of good and bad examples to truly advance our experience, whereas this model seems like it would be a stream of mini pseudo-advancements packaged in transactional wrapping to maximize creator's benefit. Saying that, I am also aware that many existing ways of monetization already work like that.

I think existing internet contains both the commercial and benevolent 'free, no strings attached' models and to me it strikes a good balance.

karol··on Farming robot kills 100k weeds per hour with lasers
I have a feeling that the creators might be wrongly assuming that we could evolve plants to thrive in extreme monocultures (no other plant or animal life). I suspect these efforts will be met with diminishing returns of a) seeing lower yields because plants don't need to compete for resources b) really hard to go beyond 99% of desired plant because of energy consumption c) weeds adapting to fool the AI and resemble desired plants in phenotype and d) people who tread on the soil to weed by hand interact with the soil in a different way than a robot on wheels.
karol··on Paid in Full: an internet where every interaction is a financial transaction
I hate the idea of wrapping all interactions into transactions. It flies in the face of an idea that might I want to give something away for free. I would then presumably need to package this into a transaction for 0 cents. Economy is part of life, but we also interact on biological, spiritual and emotional planes which may be driven by different economies.
karol··on Tell HN: Today I learned Epub is just HTML/CSS
Does it mean you could build a better web for knowledge sharing than medium and similar? It seems epub only supports a subset of CSS.
karol··on Wall Street Begins Trading Water Futures as a Commodity
You are kindly ignoring speculation. What you presented is an efficient market hypothesis, however markets are not efficient. They invite speculation bubbles and they do crash.
karol··on Twitter still hasn't unlocked the New York Post's account
It seems to work for me now: https://twitter.com/nypost/status/1316437892122710022
karol··on I was tricked into thinking I had “grit”
When I worked for a pensions company they sat me next to the CEO. He was a pleasant man most of the time, who could sometimes show a touch of arrogance towards his PA. I saw him mostly work at a slide deck all week and reading a book called Grit. Later I noticed he put a few sentences from the book into his deck. "We don't go home when we are tired, we go home when we are done" stuck in my head.

After a few years of my own struggles at being consistently productive my conclusion is grit is an emergent behaviour you cannot optimise for. You most probably want to use different words such as 'consistency' (this one works for me). I see grit as something opposite of health and balance. A short-term display of stamina that might trigger unwanted consequences in other areas of life.

karol··on I think Catalina 10.15.4 broke SSH
With this foresight he sadly didn't enable CloudFront and the website went down.
karol··on Chrome deploys deep-linking in latest build despite privacy concerns
Why is this feature so interesting it got implementation priority? Does this enable some commercial activity by Google?
karol··on Build Your Own React
What's interesting is the React team had to implement their own DOM manipulation abstraction, with efficient change management and not interrupting the main JS thread. Their implementation strikes me as a possible general purpose implementation that could eventually replace the way DOM works.
karol··on The Golden Scale: A Collection of Norwegian Folktales
This is a reminder of what the web should be about - publishing great content in an accessible format.
karol··on Prospecting for gold by looking in leaves has proven itself in Australia
Why do we need to mine for gold in 2019?
karol··on Fear, trust and JavaScript: When types and functional programming fail
The author seems to confuse static code analysis with runtime values.
karol··on Our Solar System Is Even Stranger Than We Thought
As a side note, the drawing attached to this article is of Edward Tufte's quality, so much information condensed into a simple-looking drawing and it's so easy to get the idea from a single glance.
karol··on I don’t know how to create a website
Apart from websites there are now other things that people deliver via HTTP and browser or a "web view". I would argue that the market for websites has shrunk. There is a booming market for web applications that are just the best way to create a gateway between customers and ever changing business logic. In this space there is a proliferation of tooling and compilers and it's only going to get more complicated in the sake of betterment (JS as a compilation target). I'd focus on fundamentals, one of which is user experience. It doesn't matter if the flow is created in Go, React or closure, it still needs to be user-friendly, intuitive and secure at the same time. The domain knowledge is much more important than tooling.
karol··on Ask HN: Is it too late to find a mentor after 30 for a software developer?
Broadening a subject, I was a mentor to a few junior devs and loved the experience. This was in my last full time employment. Now I became a contractor for all the perks involved but I miss my mentoring role slightly. Do you know of any good places online where I could help someone with building their skills?
karol··on NTSB: Tesla’s Autopilot UX a “major role” in fatal Model S crash
> The machine learning algorithms that underpin AEB systems have only been trained to recognize the rear of other vehicles, not profiles or other aspects.

Not something I have known about Tesla's autopilot before reading this.

karol··on Ask HN: What does your diet look like?
Typically I eat 3 meals during the day plus some snacking. My diet consists of 70% plants, 10% diary, 10% bread and 10% meat. This year I started making a vegetable-based smoothies every day to help with snacking and staying hydrated. I also add some Huel to the smoothie and so far I can say it has had a positive effect. I do not eat sweets (almost never) and I drink 2-3 coffees per day. I drink bear/wine occasionally and don't smoke.
karol··on What does ‘that = this’ in JavaScript mean?
This an ugly convention. By always using `that` you lose an opportunity to create a meaningful variable name which would be more descriptive. Why not use?

    var widget = this
Besides using more functional approach and arrow functions you can free up your code from lining methods via this keyword.
karol··on What does ‘that = this’ in JavaScript mean?
By using `self` you shadow a global variable which is a reference to the current context (window object) in which the code is executed.
