jacinda··on Good genes are nice, but joy is better (2017)
I think you may be referring to the Roseto effect. https://en.wikipedia.org/wiki/Roseto_effect

This community had unusually low rates of heart disease despite a large range of traditional risk factors. The general consensus was that this was due to the community-oriented nature of the town. Later they did follow-ups and found that as the town became more stereotypically "American" the mortality rates due to heart disease increased, especially among younger men.

jacinda··on How to organize yourself as a solo founder
Eh, whatever works. Some people like the ease of working anywhere, some people are more motivated by seeing a physical representation of their progress (possibly similar to how people remember chronological events better when read from a physical book vs an e-book or on-screen: https://www.fastcompany.com/40476984/this-is-how-the-way-you...).
jacinda··on Tim Cook tells employees the return to offices will begin on April 11th
Less mental overhead and friction in terms of setting it up. 1000s of years of evolution. The experience of people who post on HN and their comfort with digital interaction may not reflect how a majority of people feel.

I wonder if there is confirmation bias in the opinions of people who are voluntarily spending a large amount of time on forums already. They had a preference for written asynchronous communication already.

jacinda··on The war on gifted education
> I hit a wall when stuff got genuinely difficult or required significant work.

This was, to me, the greatest benefit of being put in a gifted program in 3rd grade. I was so used to everything being easy that I cried at home that I had homework taking longer than 10 minutes that I actually had to concentrate on. I asked my dad to go back to the regular program, and he said I should stick it out for at least another month. I did, and learned how to work through things that seemed challenging at first.

The experience of having to put forth effort early(ish) in my life set me up far better for dealing with life later, because I learned how to push past things that were uncomfortable instead of giving up (i.e. "grit" became a part of my psyche when it was still pretty flexible).

I probably could have learned this lesson in other ways, but the fact that it's one of my clearest childhood memories certainly speaks to the impact it had on my life. And I know plenty of friends whose first experience needing to put effort happened in college, and things seemed a lot harder for them emotionally.

jacinda··on Launch HN: Courier (YC S19) – Developer infrastructure for product notifications
Hi Troy! Was happy to see this on the front page this morning!
jacinda··on Career advice nobody gave me: Never ignore a recruiter
I hadn't really thought about this before, but your comment made me realize the costs that used to be associated with spam calls in the past.

Monetary or social costs were both asymmetrically in favor of the receiver because a long-distance call was expensive and a local spam call would eventually incur a high social cost (either in the innocent case of teenage prank calls being figured out by parents or the less innocent cases where the police or phone company might need to trace the source).

jacinda··on Don't start with microservices – monoliths are your friend
> But all those data sources are connected to from the same runtime, right?

Yes, this is an accurate assessment from what I've seen.

> And to run it locally you need access to dev versions of all of them.

In my experience, no. If the runtime never needs to access it because you're only doing development related to datastore A, it shouldn't fall over just because you haven't configured datastore B. Lots of easy ways to either skip this in the runtime or have a mocked interface.

> And when there’s a security vulnerability in your comment system your tape library gets wiped.

This one really depends but I think can be an accurate criticism of many systems. It's most true, I think, when you're at an in-between scale where you're big enough to be a target but haven't yet gotten big enough to afford more dedicated security testing at an application code level.

jacinda··on Mammals dream about the world they are about to experience before they are born
Having gone through it, while it's true you need more calories after the baby is born (I breastfed and pumped exclusively and was told it's about 500 calories per day vs 300 or so extra prior to birth) the strain on your body is lessened because you are producing a single item (milk) going to one part of your body that's drained periodically.

In contrast, by the third trimester of pregnancy, your total blood volume has increased by approximately 50% (3-4 pounds of additional blood), not to mention an extra 2-3 pounds of retained fluid, 2 pounds of amniotic fluid, and 1.5 pounds of placenta. All told, this is another ~10 pounds on top of the baby. Additionally, the mother / placenta is performing all respiratory and blood filtration functions on behalf of the fetus (the kidneys don't really do much prior to birth other than produce urine).

Personally, while breastfeeding and newborn care was exhausting, it felt more akin to training for an athletic event vs having another entity symbiotically tied to my system like pregnancy.

jacinda··on Mammals dream about the world they are about to experience before they are born
> this is commonly attributed to the fact that human babies have immature brains that cannot mature due to birth canal constraints, which is constrained by pelvis size which is constrained by the need to walk upright

Interestingly, the EGG hypothesis postulates that the constraining factor is not pelvis size, but rather that neonates consume so much energy that we give birth just before a women's metabolic limits would otherwise be overrun (leading to both maternal and infant death). Based on this, the increased energy demands of our larger brains mean that we have to sacrifice neonatal motor skills or drastically improve the metabolic efficiency of adult women.

https://www.pnas.org/content/109/38/15212

> In humans, maximum sustained metabolic rate is thought to be 2.0–2.5× basal metabolic rate (BMR).

> By 9 mo, metabolic demands of the fetus threaten to push maternal energy requirements beyond 2.1× BMR. Extending gestation by even one month would likely require metabolic investment beyond the mother’s capacity. Instead, the mother delivers and the neonate’s growth rate slows relative to its fetal growth rate, keeping both the offspring’s and the mother’s energy requirements in check.

jacinda··on Preschool children rarely seek data when observation and testimony conflict
> I guess that confirmation bias is just an efficient way of learning about the world, do not waste time if things seem to fit your current understanding of the world.

Interesting observation - in this light, confirmation bias could almost be considered a variant of Occam's razor.

jacinda··on The Document Culture of Amazon
The author implies that going to meetings later if you've already done the reading is an option at Amazon.

> If a document is provided early and I have a conflict at the begining of the meeting I can read the document ahead of time and join the meeting 10-20 minutes late without missing anything.

jacinda··on When You Get into Unschooling, It’s Almost Like a Religion
> plenty of people try it, find it doesn't work for them, and quit.

This seems like it would lend itself to selection bias - only people for whom homeschooling is a good fit continue to pursue it.

jacinda··on Tech sector job interviews assess anxiety, not software skills: study
One alternative is providing candidates with a problem to work on for a few hours on their own (have them bring their own laptop, allow them access to Google and their own development environment), then have them walk you through their solution.

Do this as part of the interview and not something they have to do in their "spare time" at home. It's not uncommon for large companies to do all-day interviews anyway, so a way to structure this can be to have the interviewee come in in the morning, provide them the problem and allow them to ask any questions they might have (as if it was a real work problem), then allow them the morning to work on it.

Then in the afternoon you can review the solution and ask them to talk through how they arrived at it and what their thoughts were during the process.

jacinda··on Tech sector job interviews assess anxiety, not software skills: study
Given that women seem to be around twice as likely to suffer from anxiety as men, this is a result I was not at all surprised to see.

jacinda··on Not everyone has an internal monologue
Yeah, I don't know about that. I definitely have aphantasia but have a strong inner monologue and can (roughly) hear things in my mind.

The only reason I have an understanding of what a "mind's eye" might be like is that I do dream visually. This is apparently not uncommon among aphatasics.

jacinda··on Nerve transfer restores hand function, elbow extension in paralyzed patients
As someone who has been pregnant and had a baby, it's much more than feeling kicking "sometimes." It's all sorts of movements, and you can even tell which part of the body is where (depending on the position of the baby). They'll even do somersaults in there before they get too big.

The movement is frequent enough that a measure of health for the baby starting about 3/4 of the way through the pregnancy is to have the mother count movements until she reaches 10, which should take between 30 minutes and 2 hours.

jacinda··on What's next for SemVer
I don't know anything about the 1 -> 6 jump, but the jump to 18 was because they switched to time-based versioning last year (2018). First release of 2019 was 19.0.

jacinda··on AWS Ground Station – Ingest and Process Data from Orbiting Satellites
Vacuums (or near vacuums) are actually good insulators. Double-walled insulated travel mugs are a great example of this.

Also, if you think about this in the context of the Sun, you get a really visceral feel for just how much energy is being produced. Black-body alone is transferring that energy to us. Scary.

jacinda··on Zulip – Open-source, threading-based Slack alternative
Oh, that’s awesome! I need to pay more attention to your Changelog.
jacinda··on Zulip – Open-source, threading-based Slack alternative
Yes, they do, if all the messages are read in the topics. Then it shows a "more topics" if you want to go back further. However, it will display all the topics with unread messages in them (even if this is more than 5).

If you're ending up with a lot of unread topics you don't care about, the answer is to mute that topic (you can mute a single topic without muting the whole stream, which is awesome but a lot of people I've worked with didn't realize you could do this).

jacinda··on Zulip – Open-source, threading-based Slack alternative
Random topics are no big deal in Zulip either. You can either a) edit the name of the topic at any time if needed or b) create a new topic as topics are cheap
