semerda··on American Academy of Sleep Medicine calls for elimination of daylight saving time
I read that “every year on the Monday after the springtime switch, hospitals report a 24% spike in heart-attack visits around the US.”. Source: https://www.businessinsider.com/daylight-saving-time-is-dead...

If this is true then daylight saving is a bigger killer than covid-19.

Why is this even up for a debate when we killed every country’s economy for Covid but here we are debating how our lifestyles will need to change if we remove daylight savings. ️

semerda··on Don't close your MacBook with a cover over the camera
Is this in response to FlexGate? https://www.macrumors.com/2020/05/08/flexgate-class-action-l...
semerda··on Vitamin D: the New Covid-19 Chloroquine?
I do quarterly blood panels to make sure all numbers are within range. All is good.
semerda··on Vitamin D: the New Covid-19 Chloroquine?
Ditto re 10K. I've been taking Vitamin D3 10K IU/day for 10 years and it has allowed my blood V-D3 levels to go from 12 ng/mL to ~50 which is within normal range. The NIH recommended dose has been going up over the last 2 decades starting at 400 IU and now 4,000 IU as we learn more and more about it's effectiveness.

Re lux with full body exposure. I was under the impression it's an hour per day to get 15-20 IU? Either way it means exposing legs, hands and face to the sun which most people rarely do on a daily basis.

semerda··on Remote work has its perks, until you want a promotion
Promotion or Responsibility? If a remote worker is trusted, gets things done and is an important cog in the wheel then limiting their growth would be an unwise decision and ultimately cost the company a great employee. So why would remote work be an issue with a promotion — maybe remote work is also a filter for below satisfactory people managers. Either way, HR will have a lot to rethink how they run.
semerda··on Moxie, a Social Robot That Helps Kids with Social-Emotional Learning
Was thinking same. Like facebook trying to connect people which they did to an extend but also gave many spite and anxiety.

The robot feels like a bandaid solution. If a robot is required then there are deeper issues that need to be addressed here.

semerda··on Moxie, a Social Robot That Helps Kids with Social-Emotional Learning
Isn't that what stuffed animals are for? I see my kids interacting with theirs. If they had a robot I'd be worried it'd spit out some nonsense (due to a bug or malicious sabotage) that could traumatize the kid. Besides that, imaginative thinking is a very important part of development (as my OT wife says) so I'd hate to kill it with a know it all robot.
semerda··on Vitamin D Insufficiency is Prevalent in Severe Covid-19
Most of us are Vitamin D deficient. We do not spend enough time in direct sunlight for an hour with all our limbs exposed.

I've been taking 5000 IU for last 10 years to maintain ~55 ng/mL after finding out I was dangerously low at 12 ng/mL. And I used to live in Australia, the land of constant sunshine.

I avoid listening to the FDA recommended dose which has historically been increasing every few years. Just get your blood work done and supplement to maintain around ~ 55 ng/mL. That's better than listening to generic advice.

Btw. This pissed me off when BlueShield few years ago stopped covering Vitamin D blood tests because of this nonsense:

Most People Don't Need Vitamin D Testing https://www.bcbs.com/news/press-releases/most-people-dont-ne...

"The U.S. Preventive Services Task Force recently found the current medical evidence insufficient to assess the balance of benefits and harms of screening for vitamin D deficiency in asymptomatic adults."

"The American Society of Clinical Pathology contributed the following recommendation to Choosing Wisely®, “Many people have low levels of vitamin D, but few have seriously low levels. Most of us don’t need a vitamin D test. We just need to make simple changes so we get enough vitamin D.”"

semerda··on Magic Leap reportedly slashes jobs and steps away from consumer plans
Unlike Magic Leap, wasn’t Segway the first personal transporter with self balancing technology? Ie. Setting a new bar. Hence others followed from that new standard. I’m not aware of Magic Leap setting any new bars.
semerda··on Magic Leap reportedly slashes jobs and steps away from consumer plans
As funny as this sounds I must agree. If they had something cool & innovative they could have shown the world and been upfront about the challenges to make it smaller. That could in turn bring new talent to help them. Instead we now see a drowning company.

In some way this reminds me of Theranos.

semerda··on Honda bucks industry trend by removing touchscreen controls
Ha! This reminds me of Navy and it’s destroyer doing the same thing.

“The US Navy will replace its touchscreen controls with mechanical ones on its destroyers” https://www.theverge.com/2019/8/11/20800111/us-navy-uss-john...

semerda··on Pro drivers are competing with gamers after F1 and Nascar canceled races
I'm sorry I should have been more clear that my car was built for the race track. Came on 2 bar of boost really hard and with a twin plate clutch meant only few people managed to drive it without stalling. A car built for the race track is not the same as your normal car. This is the difference I was trying to allude to.

But yes if you have a stock car and you take it on a race track you'll most likely be ok as long as you follow the rules.

semerda··on Pro drivers are competing with gamers after F1 and Nascar canceled races
Hahaha racing on an empty track in a car that’s built to handle like a go cart is nothing like the stress of a circuit race with other cars.

I used to race my modified turbo 500hp and I can tell you that game racing is nada to real life racing. Even knowing that taking a risk can cost you $$$ or your life is stressful enough.

With other cars on the track it’s many more variables to calculate and consider.

So let’s not kid ourselves. The delta is larger than one can anticipate without even factoring the physical stresses.

semerda··on Coronavirus has disrupted supply chains for nearly 75% of U.S. companies
Spot on! and it's not like drugs got any cheaper by outsourcing them to China. They are bloody expensive and of much lower quality than locally produced. The book "Bottle of Lies" exposes the low quality of all generics which make up 90% of the US supplies coming in from China.
semerda··on Amazon battles counterfeit masks, $400 hand sanitizer amid virus panic
Few days before the corona virus chaos started, we ordered a pack of PURELL hand sanitizers from Amazon. Then the chaos started and we wondered what will happen to our package. We tracked the package move around, then delays, then messages about possible delays, then it just never arrived.

I hit up Amazon.com and saw all these crazy markups on hand sanitizer. Eeek! But, I found 1 that was $10. Also from PURELL. Looked like the ones used at gyms. So I added it to my cart. Continued browsing and at checkout it got automatically removed. Subsequent searches revealed just the over priced hand sanitizers. Arrr!

Thanks Amazon!

semerda··on Covid-19 is now officially a pandemic, WHO says
Large-scale extreme response measures are a disaster waiting to happen.

1. 38% of nurses have children at school. Shutdown the country and 1/4 of the US healthcare industry will choose their children over work in a blink. We don't want to put any more pressure on the people working in healthcare.

2. 75% of US companies have now a disrupted supply chain. Yes the cons of outsourcing core economic functions like manufacturing drugs, hospital supplies etc... Mass mania followed by ongoing shopping sprees will set in further draining a crippled supply chain.

What we need more of is hygiene education (with strict fines) and detailed data about who, where and how they are affected by the virus. Being politically correct in a time where the world is at the brink of chaos is not going to save anyone. Sometimes hard debates need to be had and tight restrictions enforced. It's sort of like the Trolley problem.

semerda··on YC W20 Online-Only Demo Day
Try running the video stream (YouTube has VR mode) in something as simple as cardboard/daydream. There’s something calming and focusing when your peripheral vision is silenced.
semerda··on Telecoms say they have a First Amendment right to sell private data
What happens if they don’t reply or comply with the request? Is there a governing body an offender can be reported to?
semerda··on Reid Hoffman's $30M bet: Send partners, not cash, to startups
This assumes all problems are solved by throwing people at them.

Isn’t this also one of the common reason why startups fizz out burning unnecessary capital too early? Grow grow grow at all expense.

I see the value in having someone else help with recruiting et al but also see possible tension from burning unnecessary cash on headcount for the sake of growth too early.

What I miss?

semerda··on FDA clears ‘world’s first’ portable, low-cost MRI
Which country? Doesn’t sound like a US hospital.
semerda··on Every Google result now looks like an ad
Google is now an “ads search engine”. Eek!
semerda··on Epic Tells Customers It Will Stop Google Cloud Integrations
Epic is a cash cow private company. Sutter Health in the Bay Area paid $1B for its EHR. Epic stays quiet to protect its walled gardens; deeply integrated into hospital infrastructure. No doubt Google is a threat to them.

Here’s an old article I found that references this juicy revenue opportunity (the rest have been cleared by Epic, so the story goes): https://www.healthcareitnews.com/news/setback-sutter-after-1...

semerda··on Epic Tells Customers It Will Stop Google Cloud Integrations
At Sutter, every machine is Windows and runs Epic integrated. Epic is much more than EHR. It’s a hospital layer sitting ontop of Windows. Naturally, it integrates with Active Directory and I can see why Google would have little dominance.

Saying that, I wonder if Epic has a plan to go after smaller players who might be using Google Apps and fears google’s dominance.

semerda··on Visa Buys Plaid
Congrats to Plaid!

Overall, I'm no fan to these scrapers. Apart from the army of engineers (internal cost) required to maintain them, on the outside they sell a promise that is putting user's privacy at risk. This is especially prevalent in the bookkeeping space.

Many "me too apps" stitch their services using Plaid to provide bookkeepers with bank feeds & statements for their clients.

Other's use Xero's HubDoc (which Xero paid 70m for few years back) which basically does the same thing; scraping financial statements from many online services using a combination of tools and humans. It's a goldmine for hackers; plain text logins are stored in their database to practically many online accounts owned by business owners.

Amazing to what degree people will go to to save few hours of labor each month.

semerda··on Visa Buys Plaid
Open Banking Standards in Commonwealth Countries will make the need for these scrapers redundant and limit the tools use to the US only.

Never been a fan of scrapers. Very unreliable and a big security hole especially when MFA is used.

I wonder if the tightening data privacy regulations (CCPA et al) forced them to sell or whether it was just a good sale opportunity.

semerda··on Who’s Behind Those Mystery Drone Swarms? An Investigation
Curious why no one has used a telescope to check out the drones. This be a far simpler and cheaper solution than dispatching planes or landing on them. Would it not work?
semerda··on Reality has a surprising amount of detail (2017)
Ditto. Learning theory without real-life application makes it boring and people forget. Learning application without theory leads to hacks. Often the real-life application happens in the last year when it's too late for some. Maybe the interim assignments should be more real-life examples so students could see application of and be inspired to learn deeper.
semerda··on NASA Flew Gas Detectors Above California, Found ‘Super Emitters’
Where is EPA in all this?

Mountain View Shoreline (right behind Google HQ) used to be a landfill site for 3 decades before being turned into a park. Plenty of families visit it for the nature walks, kiddie play areas and water activities. Then few weeks back I heard a bang and hissing; a methane release valve opened https://youtu.be/kq3CnXU5OtU

I don’t know if this is normal for it to be so low but since then I’ve learnt the whole area has these to stop it from combusting. Methane is also a dirty gas that affects cognition.

Add to this the SuperFund sites water & land pollution and one has to question what the heck is going on here.

It gives a whole new perspective on how we are killing our earth hoping the problem will be solved by someone else in the future :(

semerda··on The iPhone 11 Camera, Part 1: A Completely New Camera
No it won’t. The framing will be identical. That’s how the DSLR world works. The viewfinder is used for framing & exposure check and then the rest is done behind the scenes.
