matco11··on The fig is an ecological marvel
A few years ago, I got a little put off by the wasps-fig thing, then, after some research, I found that wasps have nothing to do with the species of figs that are consumed by humans
matco11··on Clubhouse is the big stinker that nobody wants to talk about
For me Clubhouse worked for a few weeks, not a few days… I haven’t used it for the past few months, but I think it’s just a matter of time before they figure things out to make it more usable again:

1) I feel the growth in the number of users (and rooms) has overwhelmed their notifications-based system;

2) the “enjoy the live conversation or nothing” approach they have works great for content creators (which is key), and for people that enjoy serendipity (which is great), but makes it hard to use for many users that may just want to enjoy the content and are not in creator mode at all times.

A lot of the great stuff that happens on CH just happens at the wrong time of the day.

Adding DMs was a great way to help translate participation in rooms into something more valuable and that continues to bring value beyond (outside) CH.

I suspect next steps are going to be in the direction of:

1) supporting the many people that would be willing to trade interactivity in a room for greater flexibility to listen to it passively but at any time;

2) introducing a content recommendation system that allows users to discover the right content that is not live;

3) bring on a user rating system that relies on more than just the number of followers.

matco11··on Open Decision-Making (2014)
Lots of interesting pearls of wisdom. I really enjoyed reading this and found it useful.

Perhaps it’s me, but it almost feels like the author perceives that managing a company is the same as making a stack of decisions, and the piece covers well how the CEO relates to other employees in the decision-making process.

While making decisions is certainly an important part of what a CEO does, managing a company also involves managing how decision making happens within the organization: that often means helping decision making happen with less and less direct involvement of the CEO.

Indeed, as an organization grows, the number of decisions to be taken grows too, and so an important aspect of any framework for effective decision making involves managing people, and designing the organization, in such a way that decisions are moved away from the CEO.

In this sense, it would have been interesting to read more about when and how a CEO should let others take over the process for certain decisions, how a CEO should pick which decisions to be involved in and which should be delegated, or how a CEO should evaluate the performance of the organization’s decision making capabilities.

matco11··on Update to our privacy policy and apology
>The old privacy policy contained a provision that discouraged children under 13 years old from using the program. After extensive further consultation with our lawyers, we have determined that this provision is unnecessary given the actual mechanics of data transmission and storage.

This is great. Does anyone have any idea on how the actual mechanics of data transmission and storage can play on the legal side of things to enable use by under 13?

matco11··on What should the CPU usage be of a fully-loaded CPU that has been throttled?
Perhaps, the system should report two numbers: the % usage of the CPU overall resources and the % usage of the throttled resources.

There is no constraint that one has to use only one number. Perhaps, in 2021, CPUs are complex enough to deserve more than one number to give a useful representation of utilization, as it works with all sorts of factories/plants. Also, who would love to see in the metrics reported CPU usage per core?

matco11··on Peloton's $3k treadmill now comes with surprise 'subscription fee'
I am confused. I almost bought the Peloton treadmill months ago and it was pretty clear that the $40 subscription was needed and was on top. To me, the $40 subscription for treadmill is not new news
matco11··on The Big Alien Theory
I like this idea, but I am not convinced about how it is applied here.

If they could have made this video a 200 years ago, the population on earth would have been 800mm people, instead of 7.7bn people. Same humans, same planet, but ~10x difference in what our existence implies about population of other forms of life existing out there

matco11··on Benzene detected in many sunscreen products
Talc is a mineral in clay mined from underground deposits. It’s the softest mineral known to man and that makes it useful in a wide range of consumer and industrial products. Asbestos is also found underground, and veins of it can often be found in talc deposits, leading to a risk of cross-contamination, geologists say.

matco11··on Remains of nine Neanderthals found in cave south of Rome
that’s not what they say it happened. The human remains accumulated there over time.

From the article:

> Experts believe the individuals lived in different time periods. Some bones could be as old as 50,000 to 68,000 years, whereas the most ancient remains are believed to be 100,000 years old.

matco11··on Ask HN: What was the biggest leadership challenge of your career?
Amazing of you to share this. It will get better. You will feel better.

I understand how you feel now, but (I am sure) very many people out there would rather trust their data to (a future) you given how careful you have been, how much you have cared, and how much you have learned from this.

matco11··on Ask HN: My startup has more annual subscribers than monthly. What to make of it?
Sounds great. Maybe, in addition to working on price segmentation, one way to leverage the behavior (“stickiness” as you call it) of your users is to create a mechanism to make them refer new customers to you: you can create an inexpensive growth engine, for example like Dropbox did with its referral program.
matco11··on Ask HN: My startup has more annual subscribers than monthly. What to make of it?
Because the discount rate of the yearly plan is financially very attractive (17% off), there are really two main reasons people go for the monthly option: 1) they are unsure if they are going to like your product enough to be willing to go for the bigger commitment of the yearly subscription 2) they can’t afford the yearly payment upfront (this is especially valid for very expensive subscriptions)

On the yearly subscription, do you charge for the entire year upfront? If not, you are eliminating reason 2) above to go for monthly

How is the distribution of vintages of your user base? Depending on your growth (and churn) rate, the distribution of old (>1 year old) vs. new (<1 year) users might drive more yearly subscriptions: the slower you grow, the more old users you will have in your mix of paying users. Old users already know they like your product and are much more willing to take the commitment of the yearly subscription to get the financial savings.

...so that might explain why you have a majority of annual plans. It’s always a good idea to experiment with your prices and segment the market, it’s almost always a good idea to do it without disrupting (too much) your existing user base.

matco11··on A Brief History of the Hedge Fund
That’s what he originally had. ...Then he had a rough patch and asked his investors to switch to 2/20, so that he could keep operations running also during bad years. His investors agreed and 2/20 was born...
matco11··on Ask HN: Advice on Finding Manufacturers?
Your question does not provide much detail to go by... but three important, general principles to go by are:

1) make sure the manufacturer you are talking to is already manufacturing comparable products - efforts to make them manufacture a type of product they are not already familiar with are likely to fail;

2) make sure the manufacturer you are talking to is already manufacturing at a level of quality that is in line with the quality you want - efforts to make them manufacture at a higher level of quality than the manufacturer is accustomed to are likely to fail;

3) familiarize yourself with regulations for the manufacturing, import/export, and sale of the product you want to develop before you talk to the manufacturer - regulations will always eventually catch-up with you and you risk wasting effort, money and time not covering them in advance.

matco11··on PS5 Teardown [video]
You can see that a lot of love went in the design of this thing, both inside and outside.
matco11··on Ask HN: How do I help an underperforming team get on track
Build their confidence. Review at the end of every deployment what went wrong and what they have to change to make things work next time. Review also what they did well, so they build confidence.

Make them feel like each failure is an opportunity to learn that they need to put to good use for the next deployment.

Build a process that turns your team into an effective team

matco11··on Ask HN: What collaborative whiteboard are you using?
Miro.com is great. It is so much more than a whiteboard. We use it for brainstorm sessions, retros and all sort of things.
matco11··on Apple will host WWDC virtually, beginning June 22
Yes... if we can all get WWDC swag! ;-)
matco11··on The Petrucci Music Library
Link on Ottaviano Petrucci

“He was born in Fossombrone. Around 1490 he went to Venice to learn the art of printing. [...] Petrucci's later work was extraordinary for the complexity of his white mensural notation and the smallness of his font, and he did in fact print the first book of polyphony using movable type.“

matco11··on We need to take CO2 out of the sky – an overview of climate tech
Yes, it does.

GREAT work.

Two (small) comments: - Perhaps the review of the re-forestation option could mention that this has a number of positive side effects (outside of carbon capture), for example on rainfall and wildlife.

- as there is a time constraint on co2 capture (e.g. 2050), and as the various co2 capture solutions are not all at the same stage of maturity, it could be useful to have a table/chart that summarizes which co2 capture options are deployable now vs. at some stage in the future

matco11··on How These Things Work – A book about CS from first principles (2016)
One of my favorite books on subject is The Elements of Computing Systems: Building a Modern Computer from First Principles by Noam Nisan https://www.amazon.com/Elements-Computing-Systems-Building-P...
matco11··on Ask HN: Are books worth it?
Not all books are good.

Your learning comes from the experiences of your life. Reading a good book is like learning someone else’s life.

...That’s why a truly great fiction book may be worth 100x a truly great non-fiction book.

matco11··on Viaweb's First Business Plan (1995)
Before Google was created (and for a few years after) you would have used other search engines/portals. In my experience, the most common back then were (in no particular order): Yahoo, Lycos, Infoseek, Excite, Altavista, Webcrawler.

Also, internet service providers usually provided their own portal, to support less-experienced users.

As a company/site, you depended on - adding yourself - to the lists on these portals to be discovered by customers.

As a user, you depended on the listings on these portals/search engines to discover sites/companies you were interested in.

matco11··on MyPayrollHR CEO Arrested, Admits to $70M Fraud
The issue is that the cost of direct deposits should be lower, so that they can be more widely adopted
matco11··on Currency (Restrictions on the Use of Cash) Bill 2019
There are countries where this type of restrictions to using cash for large payments have been in place for many years. They help with: - mitigating money-laundering risk - more effective application of sales tax - more effective enforcement (in combination with other tools) against income tax evasion.
matco11··on Ask HN: What do you do with your Raspberry Pi?
1x Raspberry Pi 3 to power a weather station sampling wind direction, wind speed, air temperature, soil temperature, air humidity, rainfall and push data to Weather Underground.

1x Raspberry Pi 3 to teach the kids how to code in Python and do math games.

matco11··on Founder Books
Books influence us and shape us. We are what we are because we are formed by our experiences throughout our life. Reading a good book is like living someone else’s life.
matco11··on 25M Brits would struggle in a cashless society
It seems to me that a cashless society can have many advantages - when everything works well. Yet, cashless societies would be pretty disastrous in case of natural disasters, acts of war, acts of terrorist, industrial accidents, and any other circumstances that would take out electricity and/or telecommunications. To me that seems a good reason to kill the case for going cashless nationwide.
