drited··on Experiments on a $50 DIY air purifier (2020)
Interesting thanks! So I guess you change them weekly then?

How often (if at all) do the filters require washing to keep them going for that long?
drited··on Moderna Is About to Begin Trials for HIV Vaccine
Having taken the Moderna mRNA Covid-19 vaccine I'd be curious to hear HN'ers thoughts on this part of the article which I wasn't aware of until reading just now:

'Moncef Slaoui, head of Operation Warp Speed until January 2021, was formerly a board member of Moderna and only sold his stake in the company days after his appointment by former President Donald Trump for an estimated $10 million, prompting concerns about the program’s neutrality.'

drited··on Spreadsheet formulas for personal finance
The Datastream excel plugin from Refinitiv is one paid option used by professionals.

Or if it is just for personal use you could probably scrape yahoo's historical data tables (check their terms of use etc first of course)

drited··on Spreadsheet formulas for personal finance
How long would you expect someone in a high volatility profession to be out of work for? The logic would really only be flawed if someone became long term unemployed or didn't have enough cash reserve to cover a few months of temporary unemployment and hence was risking selling equities from savings at a time of unemployment (which could well correlate with low equity valuations)
drited··on Win at Risk by using systems thinking
Australia plus something else is good though as it both gives you easy to protect reinforcements in Australia plus the ability to influence the board elsewhere. For example Australia plus South America.
drited··on Win at Risk by using systems thinking
Agreed! There's often a little jostle during the starting land grab to get Australia: easy to defend and those extra reinforcements really matter in the early game.
drited··on Study shows how taking short breaks may help our brains learn new skills
The book Brain Rules by John Medina is worth checking out for some suggestions on possible answers. I don't think science has definitive answers yet but if I remember correctly it's thought that the circuits involved in what the brain learned during the day are active during certain sleep stages which helps with consolidation of memory due to strengthening of connections involved. It's 10 years since I've read into this but I think the biology involved was that oligodendrocytes lay down thicker myelin on axons that are active, resulting in faster/stronger connections in the circuits involved. There's also inhibitory actions of established networks which have to be overcome by new circuits which takes sustained 'attack' over time. If the inhibition didn't happen the previously learned activities would turn noisy very quickly so there's a tradeoff between learning speed and maintenance of high fidelity signal for existing pathways in the brain. I guess the brain has evolved to accept new networks from actions that are repeated and thought about repeatedly because these generally are important whereas stuff that is thought about only once probably isn't.

EU based startups led by female CEOs may be interested to know that the EIC Accelerator program aims to fund a portfolio of companies with at least 35% led by women.

At interview stage gender balance is a factor in prioritization with companies with female CEOs being prioritised until 40% of invited companies have female CEOs.

drited··on Tesla has suspended vehicle purchases using Bitcoin
This is getting to be a mindless discussion so this'll be my last response on it

>> Issue 100 million shares at 0.01 cents per share and go public. That's now a $10k dollar public company. Next, you do an increase in capital stock by selling 1 million additional shares at 0.5 dollars per share to gullible investors. See how that works and why public valuation based on share value isn't always the most useful tool in assessing a company's finances

Tesla's free float is worth over $453 billion and over $20 billion worth of stock trades each day. This isn't a penny stock whose illiquid float can be pushed around like that.

Regarding company finances, after its capital raise last year TSLA has a large cash balance. $17.4 billion at the most recent quarter end. A few hundred million from the bitcoin sale doesn't move the needle.

What matters when you're considering whether Musk would do this or not is whether it would be material to him. It wouldn't because most of his wealth is tied to the value of his stock, which in turn is tied to the market value of the company. The bitcoin profits made an impact of maybe a tiny fraction of a percent of the value of the company and his wealth. Not worth 5 minutes of his time over 3 months.

He updated his view to the correct one. Do you really want to be part of a lynch mob that makes it harder for public company CEOs to update their view to the correct one by coming out with tinfoil conspiracies to explain actions that were probably just the result of lack of attention?

drited··on Tesla has suspended vehicle purchases using Bitcoin
>>'took him months to learn'

You say that like he didn't have two giant companies to run.

He wasn't studying bitcoin all this time.

>>Q1 profits

Company valuation depends on decades of earnings. Current earnings matter little to the valuation of high growth companies.

>>excuse me

You're excused. It's clear that assessing public company valuations is not your area.

drited··on Tesla has suspended vehicle purchases using Bitcoin
While a popular opinion, that does sound more tin foil hat to me than the alternative that he updated his knowledge in the last few months and/or had his opinion on Bitcoin changed by communication from others in the organisation.

Tesla is a 568 billion market cap company. The profit it made on Bitcoin doesn't move the needle enough to justify some elaborate scheme to pump and dump. Musk is no stranger to whimsical decisions that, while involving a large amount of money in absolute terms, are not material in the context of the much larger value of his shares in Tesla.

drited··on Farming robot kills 100k weeds per hour with lasers
From the perspective of a farm /plant owner with a commodity product who is trying to compete internationally that's kind of a 'let them eat cake' solution though isn't it (not robotics - a wage hike)? Margins can't be much above the minimum to earn an OK-ish return on capital in such an industry. If that move makes them unprofitable then it's not a viable solution.

You should have googled the situation before you made that assertion. Her father is in jail for 22 years due to the atrocity of the crimes he committed in his attic against that 10 year old girl. Per news coverage of the matter in the Guardian the role Aimee gave him after he had been charged with child abuse and rape(1) quote 'may have allowed him to interact with vulnerable people.'(2)

It is also of note that the claims the 10-year old girl made about the abuse conducted in the attic of the family home aligned with what the police found in the attic on the day of the arrest.

drited··on Ask HN: What was the biggest contributor to your happiness in the past year?
Spending time with my kids (but that isn't a change from normal times).

Since I live in a rainy country which enforced a 5km movement restriction over the winter and have young kids who needed home schooling and minding in the evening, what was a change was exploring different apps in VR after they'd gone to bed with the Oculus Quest 2. There's something about getting out into different places.. Seems like a basic human need. VR helped to scratch those itchy feet!

While I was stuck at home I even switched from working out on the cross trainer to working out with The Thrill of the Fight VR. I was amazed to discover that by really going at it I can get the same or better workout heart rate stats in Thrill of the Fight to the fairly intense level I was doing on the cross trainer. So much fun. It really doesn't take much motivation at all to work out that way.

drited··on New report on Apple’s VR headset: 8K in each eye, potential $3k price tag
Those are terrific resources, thank you!
drited··on New report on Apple’s VR headset: 8K in each eye, potential $3k price tag
This was amazing to read thank you for taking the time to discuss all of these VR tools and how they are used. I have a friend in a similar situation who is getting an Oculus Quest 2 soon and this information will be very useful to them.

Best of luck with the app development it sounds fantastic m

drited··on New report on Apple’s VR headset: 8K in each eye, potential $3k price tag
What about if you could sit next to your friends in VR to share the excitement even if they're physically remote from you?
drited··on New report on Apple’s VR headset: 8K in each eye, potential $3k price tag
Add the ability to watch the game with all your friends next to you in VR sharing the excitement just like you would if you were in the stadium sitting next to each other and that's a killer app IMO. I think the sky sports app in oculus is like that but haven't tested it
drited··on GameStop Is Rage Against the Financial Machine
Yes true but a green shoe (to the hedge funds who need to exit) could be done more quickly.
drited··on GameStop Is Rage Against the Financial Machine
If part of the 200 paid for your long position in the share was paid for with a margin loan, then you may only have put 40 of equity in the account with the remaining 160 paid for with a loan. You're exposed to a maximum loss of 200.
drited··on GameStop Is Rage Against the Financial Machine
If it gaps down stop loss orders won't execute at the stop loss order price (because there is no buyer at that price). Therefore previous paper profits are not locked in with certainty with stop loss orders. You need prices to swoop down in an orderly way with sufficient liquidity for stop losses to work in the way I think many imagine they do.
drited··on GameStop Is Rage Against the Financial Machine
Yes and if it gaps down their broker won't be able to sell fast enough to cover the margin loan. The broker can then usually come after the person's other assets (ie traders can lose more than the cash they transferred to the account in the first place).
drited··on GameStop Is Rage Against the Financial Machine
The company could issue new stock (to get a lifeline of cash from inflated price)

I know someone who tried to convince VW management to do that during the Porche/VW squeeze. They didn't but I see no reason why another management team wouldn't act differently.

drited··on Over 80% of Covid-19 patients in a hospital study have Vitamin D deficiency
This isn't really a 7th option because it overlaps with some of the previously mentioned ones, but perhaps individuals who don't supplement with vitamin D are more likely to catch Covid-19 because they also don't take other precautions like wearing masks.

Anecdotally it seems those I know who are most concerned about Covid-19 know all about the possible link with vitamin D and are taking supplements while also being careful by wearing masks, sanitising etc.

drited··on Vitamin D, part 1: back to basics
I sense you didn't read the 1500 words? Most of it is about the very item you raise, i.e correlation not causation.
drited··on Coronavirus: Oxford vaccine triggers immune response
The OP was critiquing the media reporting on the study not the study itself so I think your suggestion that the OP misunderstood the point of the study is off base.

The OP did not claim that the study sought to answer the questions posed. The article does answer the question 'Is it safe?' with the word 'Yes' so I believe you are actually in agreement with the OP and the OP did understand that it is really early to say that, hence the critique.
