athenot··on The EU sets the limit for bank transfer time to 10 seconds
This is changing with FedNow, where payments settle fast enough for synchronous applications.

athenot··on Expensive fridges are dying, leading to fraud claims
Mine does that too. Took off the back, found the drain where the condensation is supposed to go to. It's made of rusted steel. It's supposed to lead to the compressor where the heat makes it evaporate back into the room. But since it's rusted, it clogs and then eventually ices up, so the water spills into the inside back and lands under the vegetable tray.

I cleared mine out, all happy, and 3 months later it clogged back again. I don't bother fixing it because I need to remove all the contents of the fridge, then dissassemble the inside rear of the fridge to get access to the right spot. It's just a bad design.

athenot··on Ertdfgcvb
Yes the play area has an interactive renderer and an editor, with lots of fun builtins that one can modify in real time. Very cool stuff!

athenot··on Stockholm to ban petrol and diesel cars from centre from 2025
Having lived in both Europe and the US, yes you are correct that owning a vehicle does make many things more practical.

On the flip side, being required to drive everywhere because there is no transit option is a negative impact on quality of life, especially in cities.

Ultimately it comes down to how good the transit infrastructure is. Some cities make transit feel effortless and get you anywhere you need to be; others make you battle your way through it and lose a lot of time.

athenot··on Live near your friends
Since moving is not an easy proposition, taking the problem from the opposite end can be useful too:

Make friends with people who live near you.

Even though neighbors (or people in the neighborhood) may not be the "perfect friends" meeting all the common interests, I'm often surprised by really nice people in the area, people who I overlooked because I judged them too fast; cultivating those connections eventually creates new friends.

If you had a say in where you're living (as opposed to be forced to live there out of hardship), there are probaly at least some commonality with people nearby. Cultivate the common aspects and look past the differences as much as feasible. Human connections are rich and highly multi-dimensional.

athenot··on The dark side of tech culture
It can breed a culture of micromanagement. "Employee can only work X hours, we need to extract as much value as possible."

Yes, micromanagement will go against actual performance, but that's not how many managers are tempted to see it.

athenot··on Principles for building and scaling feature flag systems
Not OP but multiple code bases may refer to the same flag by a different constant. Having a single string that can be searched accross all repos in an organization is quite handy to find all places where it's referenced.
athenot··on Sorry, Your Paper Coffee Cup Is a Toxic Nightmare
The shop I go to offers a 50¢ discount to people who bring their own coffee cup. It's not that hard from a hygiene perspective: they have the cashier (who is already handling "dirty" money) walk over and fill the cup.

(I drink black coffee so I don't know if that applies to the specialty drinks; those are made by someone else.)

athenot··on How to drill your own water well
Thanks for posting this; I have Georgia granite under my feet in random and unpredictable quantities. I've noticed most of the "success stories" in the submitted article happen to be in sandy areas, or with softer ground.
athenot··on Japan’s 72 Microseasons (2015)
This is a very perceptive way to watch time pass when watching nature—and definitely useful when life revolved around things growing in the groud.

I wonder how much drift there is on the dates given, or if local climate yields highly predicatable weather patterns.

For example here in the South-East US, the "last frost" date can vary from mid February to late April but our weather patterns are higly variable.

athenot··on Ask HN: Where to find open-source house plans?
Humidity is one difference that comes to mind.

In most of Texas, the air outside is humid, you need a moisture barrier between your structural wall and your rainscreen/siding.

In Calgary, cold winters will have very dry air, so the humidity will be much higher inside the house. So the moisture barrier needs to be on the other side.

In either case, you don't want the insulation layer or the structural layer to be collecting condensation from the humidity / temperature differential, or you will get mold.

Disclaimer: not a builder, just deal with humid climate.

athenot··on A good measurement culture where numbers don’t replace common sense
> which was the threshold to qualify for your bonus

This is the problem: tying OKRs to bonuses. It sounds so logical from a naive standpoint and yet it has so many detrimental side-effects.

Where I'm at, we have a hybrid system that works quite well. OKRs are divorced from bonuses; and they are always "Stretch OKRs", ie. ambitious ones. Essentially they are the compass where team is headed. Then there are MBOs which are tied to bonuses. These are very conservative, so that the bonuses are attainable.

With this system, in practice, the MBOs are the subset of the Key Results that actually seem achievable within the quarter.

Of course there's a functional way to play this game and a dysfunctional one.

Working, functional version: spend time defining actual Objectives, regardless of whether we know how to measure them. That last point is very important. Only when the Objectives are defined (and they are almost always qualitative in nature), THEN come up with Key Results, to try to quantify the objective (and be open to adusting that). Finally, pick out the KRs that can be realistic, and make them the MBOs.

Dysfuntional version: start at the opposite side. Define MBOs. Then Key Results. And finally, try to BS some form of Objectives to make it all sound coherent. This biases towards both what is easy to measure and easy to quantify, to the detriment of business needs.

athenot··on Low dose radiation cancer 2x worse than predicted by LNT model
They wear 30lb lead aprons. On a practical note, it's back strain from having that thing on 10-12h a day.
athenot··on Rail company that launched first H2 line opts for all-electric future
Interestingly, the total amount of rail is about the same for EU and US, however in the EU, 55% of it is electrified, and only 1% in the US.

athenot··on PRQL: Pipelined Relational Query Language
I had the same question. From the docs, it looks pretty elegant:

    from employees
    join side:left positions (employees.id==positions.employee_id)
which translates to

    SELECT
      employees.*,
      positions.*
    FROM
      employees
      LEFT JOIN positions ON employees.id = positions.employee_id

It's also the materials used in modern furniture, which catch fire faster.

athenot··on The past is not true
This touches on Narrative Therapy. Events happened, yes. Facts are immutable and can't be changed or wished away simply because they are inconvenient.

Rather, how we make sense of them—and internalize them—affects our lives in significant ways, especially if the prevaling narrative we believe about ourselves prevents us from thriving.

athenot··on When Work Didn’t Follow You Home
10 years ago the specialty bulbs were all metal halide and CFLs but nowadays, they are LED and much better; some are even dimmable. Sites like 1000bulbs let you search by type, brightness (in lumens), color rendering index (CRI; over 90 is best), temperature (in K), angles (for spotlights).

Many people spend a small fortune on light fixtures and then use the cheapest bulbs in them. I prefer the opposite.

athenot··on When Work Didn’t Follow You Home
Point 1 is very important, I can confirm with also a decade of doing this.

One note I'd like to add is pay attention to your lighting, have a special "work-mode" set of lights that you turn on when you work and then turn off when you are no longer working.

I use the same work desk for non work stuff, but I turn off my "office lights" and it's a completely different vibe.

Everyone's tastes will be different but as for me, these are my preferences:

- Office lighting: at least 20k lumens of 5000K light with high CRI. For me I like to approximate the brightness of daylight. It's especially useful during the cloudy days of winter. My office is in a basement so the cheapest way to do that is string lights (like for outdoor patios), but with high quality LED bulbs.

- Personal lighting mode: regular house lighting, 3000K (so skewing towards a more yellowish, incandescent-like light). I still enjoy high CRI because I can't stand things looking bland but that's less important. More spot lights, less ambient light.

athenot··on Turmeric’s unexpected link to lead poisoning in Bangladesh
It's used medically, for example for nurses and doctors who work with radioactive tracers; they wear big aprons with lead in it which absorb any radiation that would be ok once in a while but that you don't want exposed to every single day at work.
athenot··on Why [“1”,“2”,“3”].map(parseInt) yields [1, NaN, NaN] in JavaScript (2011)
The article mentions using the Number constructor, which is even more elegant:

    > ["1","2","3"].map(Number)
    [ 1, 2, 3 ]
athenot··on The Pentagon’s $52k trash can
This is similar to hospitals sometimes billing $300 for a simple saline IV bag. Creative accounting where the cost of highly scrutinized items is reduced, so other items are inflated to essentially make up for the difference.
athenot··on Turning Joe Rogan down was the right thing to do
Productive scientific debating is usually done in writing, or over long periods of time, not in entertainment-driven TV shows. It's unfortunate both are called "debating" but mean something very different.
athenot··on How to do the thing you've been avoiding
Many of the comments here are about procrastination (and are all very good contributions to the topic).

However the article is more about expanding our thinking and challenging limitations that are self-imposed, which then prevent us from taking certain actions that can be highly significant (if not downright pivotal) for the goals we're pursuing in life.

Personally, one of my favorite phrases is "what if?", in a dreamy, anticipatory mindest of wondering what might be possible. Sometimes this allows me to see that an "evident" limitation can indeed be overcome.

athenot··on Rivian embraces Tesla's charging standard for EVs
This is true. Though the electric batteries do have the advantage of having already paid the "thermodynamics tax". Some of the energy in gas will go towards heat losses; energy that cannot be converted to movement.
athenot··on Surges of cosmic radiation from space directly linked to earthquakes
Maybe not control but the ability to have an advance warning would be a huge gain in terms of public safety.
athenot··on Linda Yaccarino is the new CEO of Twitter
Indeed, these are 2 different skill sets. But wouldn't that be a Chief Operating Officer then, instead of a CEO?
athenot··on Are We Close to AGI?
Both can be true.

On the one hand, I welcome the ability to leverage machines to automate work that I find boring, with ever-increasing complexity and cleverness. This frees me up to remain in the creative thinking headspace, and interpersonal relationships which are oh-so-necessary to build products. From a team perspective, this also allows a fixed-size group of engineers to take on ever increasing scopes and scale.

At the same time, society at large operates in a very different mode. I would argue that it has not finished "digesting" the previous technological advancements. While disruption is something to be celebrated on a personal level, in a society, it starts out as a net negative before benefits start to be realized. And as usual, it is the most vulnerable members who suffer the most, and the most powerful who gain the most.

I am optimistic in the short term for myself and in the long run I think it will be beneficial for society. But there will be a lot of pain born by the vulnerable.

athenot··on What I learned unsubscribing from 22 newspapers
Another option would be to mail a physical letter to their billing department stating that you are cancelling your subscription 30 days from now and any subsequent charges to the credit card will be disputed.
athenot··on A man who walked around the world
Part of this is an interesting side effect that interacting with people 1:1 is different than when the interaction is intermediated by a group or an ideology or a commercial platform.

I find that when I strip away group dynamics, people all have similar basic needs; that many fears are shared; that many people have similar hopes even if specific struggles or needs vary greatly.

Yes it's disappointing to find out that a nice person turns out to be part of a digusting group, but on the flip side, sometimes seeing the humanity in different people can help lessen the ideologic stronghold on some people. I have some narrow-minded friends and relatives who have been a bit less categorical just by hanging out with nice people who think totally differently than them.
