sparsely··on Show HN: Resume maker with no sign-up or subscription
Very clean, nice work!

My main feedback would be to make the photo optional - it's quite culture and job dependent whether a photo is included on a CV.

sparsely··on Trailerduck is a smart e-bike trailer
There's a big difference in perceived (and probably actual) safety between sharing a narrow bikelane with current pedelecs and an electric moped. I do think that the use cases for bikelanes should be made more explicit and varied, but unless cities start building substantially bigger ones I don't think they can get much faster.

In any case, in cities something which can go over 25kph without pedaling is likely safe enough to drive like a vehicle.

sparsely··on Footage of Australian Raven Attacking a Wing Drone in Canberra, Australia
How much noise do these make? Camera drones in parks are already pretty loud and that thing looks even bigger.
sparsely··on Michelin's airless tires are scheduled for market launch in 2024
There have been a number of reports of components of rubber tiers being harmful to humans[1] or the broader environment[2] beyond the waste issue, would be interesting to know if these manage to improve on that.

sparsely··on China’s dodgy-debt double act
"Smart" money has been betting against Evergrande for years, and losing money on it until very recently. I heard of one asset manager who in hindsight was totally correct about the fundamentals give up trading them at all, they so consistently lost so much money on it (the market can stay irrational etc.). It's a dangerous game!

Mike Bird at the WSJ has been going on about this for years as well.

sparsely··on AI movie posters
Impressed by the prominence of the peaches in the Call By My Name poster.
sparsely··on More wind energy was installed in 2020 than any other energy source
It depends on the region obviously, but often peak wind power is in mornings and evenings, which complements solar nicely.
sparsely··on Why observability requires a distributed column store
TIL! Still, the common usage within technology is not that meaning, and many of the claims are put perhaps more strongly than is justified.
sparsely··on Why observability requires a distributed column store
Both articles try to redefine "Observability" into a set of requirements that (they claim) only their product meets. It's fine to argue that your product is the best, but it's a bit much to come up with an entirely new definition for a widely and loosely used word, which is not that similar to the common meaning.

Why X requires you to buy our product
sparsely··on PlsExplain: A small dynamic programming language where every value is explained
F# definitely has the most complete implementation that I've seen, I'm sure other languages would let you hack something together though.

sparsely··on PlsExplain: A small dynamic programming language where every value is explained
F# does exactly this, except it understands the rules of units cancelling etc.
sparsely··on Demand for air conditioning is set to surge by 2050
The significantly reduce heat from solar radiation - you might still need AC units, but they need to do less work and be on less often.
sparsely··on Demand for air conditioning is set to surge by 2050
The difference in design between buildings in hot European countries, which almost universally have shutters and other forms of shading, and American ones which might have a porch if that, is striking. It's an extremely effective, cheap, and low carbon way of controlling temperatures which only requires small changes to design and behaviour.
sparsely··on Second Hottest July in Europe on Record, Third Warmest July on Record Globally
Greece and Eastern Europe have had real scorchers, some of my colleagues there have been having miserable summers
sparsely··on Use Spreadsheets Everywhere
I think Airtable is starting to get us there, but it's a long way to go.

Something that combined Airtable, excel, and maybe a more userfriendly (and more restricted) version of darklang for defining formulae could be really slick.

sparsely··on Entire German bond yield curve back in sub-zero territory
Someone should go tell the German government this, over loadspeakers, outside their homes at all hours until they actually get on with it and do it.
sparsely··on 5 Habits of Highly Ineffective Remote Workers
I feel like more and more Medium articles require a login now. It's a instant tab close from me. Surely there's a better way to host your text articles for free?
sparsely··on A monorepo misconception – atomic cross-project commits
I don't think synchronized deployments is really possible - you'd have to either still do the iterative thing, or possibly have some versioning system in place
sparsely··on The Utility of Mathematics
That's my understanding as well (although I have no idea what his opinion on "external reality" would be - probably that we can't test any theories about it as opposed to the world of human perception, so it isn't a useful idea).

I think the way some philosophers tend to phrase it is that we develop mathematics as a common language which we agree to use to communicate our theories, which we can attempt to verify via perception. Our choice of axioms etc is pretty free, but we tend to pick the ones which are both minimal and most useful for communication and making verifiable predictions.

I think that where the positivists and Quine differ is that the positivists say that once you have chosen axioms, you can make purely analytic statements, whose truth (within that system), only depends on reasoning according to those axioms, as opposed to statements whose truth does depend on our perceptions. Quine disagrees either that this is a useful distinction or that there is any difference at all, I'm not sure.

sparsely··on The Utility of Mathematics
I'm not knowledgeable enough about their works to say anything interesting, but on the philosophy side of this there were a lot of developments in the 20th century, notably the logical positivists (e.g. Carnap) and later Quine.

Quine disagrees with the logical positivists in a way that I find a little tricky to pin down, despite his and their writing being much clearer than "continental" philosophers, but I have found everything I've read from either camp very thought provoking.

sparsely··on Edgedressing
The only real solution to this would seem to be some sort of standardisation about how captive portals should work, but the providers of these services don't seem like the sort who would jump on to that sort of thing quickly.
sparsely··on 30 Years in Hong Kong
That's the same sort of freedom that the foundation's name refers to, so SA scoring well adds up.
sparsely··on SQLBolt – Interactive lessons and exercises to learn SQL
Nice and interactive, seems like a good place to start.

Although the second question ("Find the director of each movie") does accept "SELECT title as director FROM movies;" as an answer.

sparsely··on Functools – The Power of Higher-Order Functions in Python
I think you've kind of proven the op's point, these all have different patterns and are in different places.
sparsely··on Cryptocurrency Blockchains Don’t Need to Be Energy Intensive
If you're doing productive work then you're already producing something of value, and can likely sell more easily and safely using the existing financial system. It would have to be some sort of productive work that is not otherwise valued due to limitations in our economic system, perhaps climate change related actions as explored in Ministry for the Future. Still seems like it would just be easier to pay people normally to do that work.
sparsely··on Temporal: Getting started with JavaScript's new date time API
The Temporal proposal is dramatically better than moment.js (and Luxon, the better version of moment). It accurately models a much wider range of time based concepts, and draws on (mostly just copies) the last 30 years of developments in this space from other languages (mostly Java)
sparsely··on Reading Grossman's “Stalingrad” and ”Life and Fate”
He was! He worked on "A Writer at War", and if you check the quotes and references in Stalingrad a huge number are from Grossman or Ehrenburg
sparsely··on Reading Grossman's “Stalingrad” and ”Life and Fate”
Life and Fate is a truly incredible book - readable, thought provoking and deeply moving. Wildly underappreciated.

There's also an excellent translation with light commentary of Grossman's journalistic notes and articles from the war, "A Writer At War". Something that separates him from even certain more modern commentators is an intense concern for the experience of the ordinary soldiers, not just the cut and thrust of grand strategy and leadership.

sparsely··on Deep JavaScript
I glanced through it and it has some interesting stuff, but I suspect you'll write better code in 99% of jobs if you don't read it, and don't know about most of the techniques described
