quantisan··on Ask HN: Designing the IT infra of a non-profit with a IT team of 1?
It sounds like they have a stack that's working already, is that correct? If that's the case, why are you tasked to re-design it? Why not keep things running and improve only when and where it's needed?
quantisan··on Ask HN: How to get better at higher level thinking?
One way to improve your ability to step back and think about the bigger picture is to make a habit of regularly reviewing your goals and priorities. This can help ensure that you are always working on the most important tasks and that your efforts are aligned with your overall objectives. Additionally, it can be helpful to break larger tasks down into smaller, more manageable chunks, and to make a plan for how to complete each step.

Another effective way to improve your ability to see the bigger picture is to gather input and perspectives from others. This can help you to consider different angles and to gain a more well-rounded understanding of the situation.

Additionally, taking breaks and practicing mindfulness can also help you to be more aware of your thoughts and to better understand the bigger picture.

Finally, Reflecting on your past mistakes can also be an important learning tool and can help you to avoid making the same mistakes in the future.

quantisan··on Remote startups will win the war for top talent
Regarding too easily getting frustrated over messaging, I have only one rule to avoid that and it's been working well for me -- Whenever any message threads that requires more than back and forth once over, hop on a Zoom call.
quantisan··on MyNoise – Background Noise Generators
We programmed this at a company hackathon a while back. We pivoted and presented it as an "open office eavesdropper" because our naive algorithm amplifies distant speeches pretty well unexpectedly. https://github.com/Quantisan/nullwave
quantisan··on Lessons learned from running Apache Airflow at scale
I feel you. That's why we wrote a little library on top of SFN so that we can program SFN with Clojure instead of YAML https://github.com/Motiva-AI/stepwise. Application code sits with SFN definition and SFN Tasks are automatically integrated as polling Activities from Clojure code.

Thoughtworks made a case for this distinction in https://martinfowler.com/articles/cant-buy-integration.html#...

quantisan··on When hiring developers, have the candidate read existing code
how do you ensure consistent criteria between candidates and avoid unconscious bias?
quantisan··on Ask HN: How to assess low ego personality during an engineering interview?
OP here. I ask the candidate to describe a time that they inconvenienced others. Describe the situation, what happened, what happened afterward. Basically poking at the situation to identify humility and accountability.

I'm not entirely convinced of this approach because it bias towards people who are good at interviewing or telling a story. So I'm wondering is there other method you found useful?

quantisan··on Ask HN: What cutting-edge technology do you use?
Changing the perspective a little... A few years ago, we applied client-side applications and edge computing for chicken farmers in Mozambique. https://www.quantisan.com/facebook-loving-farmers-of-mozambi...

That was a fun side project but I got ahead of myself in the tech and failed on finding a product-market fit.

quantisan··on Ask HN: Show your failed projects and share a lesson you learned
I spent a year during and after grad school writing a blog and building a tiny community on healthy living for elderly people. I remember a particular article I wrote on eating pineapples for healthy bowel movements really offended some in the community.

My grad research was on AI and robotics for elderly. I thought I knew my audience. How wrong I was. I didn't even reach out to talk to my audience, for crying out loud.

10 years later when I was working on a project for smallholder farmers in Mozambique. I made the point of moving myself to Africa and working alongside them for weeks. https://www.quantisan.com/facebook-loving-farmers-of-mozambi...

quantisan··on Ask HN: What's the best book you read in 2021?
The Relaxation & Stress Reduction Workbook by Davis, et al.

I was so stressed out to a point of collapsing, needing transfusions, and then being physically disabled for a month this year. Startup trouble, new baby complications, first child sleep regression, etc. all happening within weeks.

This book, with its practical, actionable suggestions, saved my sanity.

quantisan··on Genetic factor may soften Covid blow for Japanese: study
I can't tell if this is the ongoing Japanese media pushing their "Japanese is superior" agenda or is this legit...

for context, the local media has been going overtime spewing out outlandish theories on why the Japanese COVID numbers has been so low despite having all the recipes for otherwise. e.g. see their "This is a pen" test on TV comparing Japanese vs English https://youtu.be/mtnVU4BU39E?t=121 (youtube link directly to the cringey segment)

quantisan··on How credit cards make money
Frank Abagale (most known in Catch Me If You Can) has said that

> Every time you use [a debit card], you put your money and your bank account at risk. > > Instead, use a credit card. I use one for practically all of my purchases, even when I’m traveling abroad. With credit cards, federal law limits my liability if there’s an unauthorized use of my card. > > When I use a credit card, I’m spending the credit card company’s money every day until I pay my bill at the end of the month. Meanwhile, my money is earning interest in a bank account.

quantisan··on Ask HN: If the Internet were redesigned today, what changes would you make?
even before new requirements come up, some of the idiosyncrasies or edge cases would be overlooked in the new version and the project would take much longer than anticipated.

if the current tech is so messed up to warrant a re-build, why would one expect that all the requirements are properly captured?

having said that, stepping back and articulating the existing problems could be a viable first step. Identify and scope the problems before dreaming of solutions. /product engineer and party pooper hat off

quantisan··on The unintended consequences of working from home
I also live in rural Japan (Nagano) and work remotely for an oversea company for the past 4 years. I second that having some daily overlapping hours with the rest of the team is critical. Once me and my family got the hang of the shifted hours, it's a comfortable balance.

Indeed. The linked Apple Support page marked the page as published on Oct 1, 2019 so I assumed it's new.
quantisan··on Learn more about iCloud in China mainland
Learned this from one of the Blizzard threads [1]. I'm surprised this move by Apple went unnoticed on HN.

I'd love to see more real world examples too.

quantisan··on Clojure at Netflix (2013) [slides]
We use Clojure for the whole backend, Python for machine learning, and JS for frontend at Motiva AI. It's the fourth company that I worked at (UK and US) with Clojure as one of the main languages. I'd say hiring Clojure devs has been one of the best perks for working with Clojure. Consistently high quality people that I've had the honour to work with.

At Motiva, we've dabbled in other languages like Haskell, Scala, Rust, Go, etc. but Clojure has been what sticks for us on the backend team https://github.com/Motiva-AI. We are a fully distributed remote team and we are hiring. Drop me an email.

quantisan··on Ask HN: What's the mission of your company and why does it matter?
At https://ingrower.com, we provide a farm management app with human-expert assistance for smallholder farmers in East Africa. There are 500 million smallholder farmers in the world today. Most are operated by women of the house in developing countries growing greens or raising chickens in their homes. Imagine enabling some of them to generate an income with their smallholding farms. That's what we're trying to do at InGrower.
