saberdancer··on Where have all the insects gone?
If I was one of the richest man on the planet, I would also invest in various fields, which would probably mean I end up one of the single largest owners in that field (through sheer fact I am one of the richest people on the planet).
saberdancer··on Where have all the insects gone?
"An NBC News analysis also identified Gates as the largest farmland owner in the US.

Almost 300,000 acres is a lot of land for one family or private individual to own, but it’s still just a small part of the estimated 911 million acres of farmland in the US." - https://www.vox.com/recode/22528659/bill-gates-largest-farml...

Not sure what is the point of this "Bill Gates is single largest holder of US farmland" narrative. It seems like a conspiracy theory in the making.

When put into perspective, amount of farmland he owes is not that big, if it was in a single square it would be 20x20 miles.

saberdancer··on Leave no trace: how a teenage hacker lost himself online
It seems that they didn't need that mistake if they were checking connections to the VPN from KPN users.

They could do a cross reference by checking his connections to the outside and then times when the hacker was "attacking". They could also drop his internet connection for a bit to see if the hacker gets disconnected.

And looking at how it was portrayed, it's doubtful his PC was "clean", especially if they catch him in the act.

saberdancer··on Amazon copied products and rigged search results to promote its own brands
Difference is that in retailers, they take on the risk and product research. They buy the items from manufacturers, sell it and then sometimes they make their own cheap unlabeled versions (usually buying from the same manufacturer).

Amazon is offering a big open marketplace where they invite people to offer goods, then they observe which goods sell well and how are they made, then the push out the sellers and they offer their own versions of it, essentially pushing the risk onto sellers and only reaping the benefits.

They are abusing the trust of sellers on their platform and they get away with it because of their sheer size.

saberdancer··on Do Dev Careers Die at 35?
I'm 37. In the last 3 years I've become an independent contractor and I'm trying to build a small software development agency. It's slow going but it is the path that appeals to me.

I feel a lot of people move to dev management when they get older or just find a spot where they feel comfortable and the pay is good.

saberdancer··on Up to 600 watts of power for graphics cards with the new PCIe 5.0 powerconnector
Yes. That's one of the benefits.

Some people use electric heating even without crypto so using GPUs to mine crypto to get the same effect is a no brainer.

Problem is that during the summer you have to get rid of the excess heat, so you need air conditioning or perhaps open air cooling.

Not gonna lie, I've used my GPU to heat up my small room before.

saberdancer··on Solar-powered aircraft flown for nearly three weeks without landing
You are right but it depends on the skillset and general lifestyle needs of the person. I've watched (a little) some of the sail around the world channels on YouTube and one couple moved to a performance trimaran, the guys reasoning was that he wanted to have speed to get out of the way if the weather changed.

For those that do not really stray far from the shore or who are willing to take more risk for more comfort, they use a slower boat.

saberdancer··on Choosing the Right Wall Anchors
Plaster can be very thin and it isn't sandwiched between sheets of wallpaper. It's used to smooth out the wall texture.

You can also have concrete wall with plaster and then on top of it paint, no wallpaper at all.

saberdancer··on Open Source Tax Software
Yes, but the problem with taxation is if you are couple of months behind the change in regulation, you are in violation and depending on the country, you need to pay fines.

It's easy to have open source project where the stakes are "bad translation" or something that doesn't result in fines or problems with IRS/law.

saberdancer··on Watering and draining planets – math and data
Density does not have to be uniform.
saberdancer··on Dude, where’s my stuff
What really changed in those 40 years? He is still doing the same job, with the same effectiveness. It's not really unexpected that the $/hr would remain the same. Honestly I am more surprised that it correlates that well to inflation.
saberdancer··on Dude, where’s my stuff
With sufficiently high wages you can get people to change jobs to become truckers.

Problem here is that truckers are not working in vacuum, their wages come from the transport of goods. If the goods have low margins, wages of truckers cannot increase by much.

saberdancer··on What it's like to spend 40-50 hours in VR every week
I am always amazed that people tend to make this into such a big problem. I've used Quest in the sunlight, you just have to be aware of it and remove it carefully, if possible while in shade. With the passthrough or just moving the headset slightly above your eyes you can do this very easily and safely.
saberdancer··on 'Dieselgate' trial opens in Germany without ex-VW boss
I watched the video and I did not understand why would they go to such lengths to use "alternative" mode most of the time, only using the proper one when in the NEDC cycle. Only downside I could understand from the talk is that it would use more AdBlue which seems such an unimportant thing.

Is there something I am missing?

saberdancer··on Remembering When Only Barbarians Drank Milk (2018)
Your butter is probably modern factory made kind, which is pasteurized. It can last much longer than "natural" butters of old.

Same applies to milk. My parents used to boil milk up until 20 years ago, mostly because they grew up in households with cows and they boiled milk to kill bacteria. It took me years of showing them the label "Does not need to be boiled" to get them to drop the habit.

saberdancer··on Will the rich world’s worker deficit last?
Anywhere where the product can be imported from abroad. If you can buy product A from Mexico for 10 USD, but can't get workers to produce the same product for 10 USD in USA, you cannot realistically increase the price.
saberdancer··on Will the rich world’s worker deficit last?
And this is why raising minimum wage can lead to opposite effect than expected. Person making that 100 dollar product may be already at the limit of profitability for that specific product for the company. Raising minimum wage can cause them to become unprofitable, which means that the worker is let go.

For those with low skills, this can mean unemployment, even permanent one.

I think that a lot of the "worker shortage" is in fact companies being unwilling to understand that they are being outcompeted in the market, someone is able to make that 100 dollar product less costly and thus can attract more workers, or alternatively workers/resources cost less abroad.

saberdancer··on Fall of Saigon
If you don't expect Afganistan to fall to Taliban, why would you pull out?

I'm baffled that they made this big of a mistake, but if you operate from the assumption that ANA does not fold, you have no reason to pull out your embassy personnel or civilians in general.

saberdancer··on How Sweden became the Silicon Valley of Europe
Bank has their own system which uses a token to authenticate. It used to be a 2FA with a physical device but now it's a mobile app.

Government services have multitude of methods to log in, they include using a government issued ID with a card reader or using on of lesser auth methods like using the bank token.

I don't think you can use your government ID to log into your bank, even though it would make sense.

saberdancer··on American parents are sending their kids to 'Russian math' (2017)
My father repeated a year, bounced back from it and became a teacher later in life.

But usually it did not happen that often. When it did happen, it usually meant someone will change schools to a less demanding one (if in high school). So for example you may leave a gymnasium and go to a school for mechanics.

In elementary school it did not happen except for serious disciplinary problems. People with mental problems were able to have special programmes that tailored to their needs, so this did not result in repeating a year.

Teachers did not really like the idea of having someone repeat a year, so if you had a decent attitude you could get a passing grade but you had to put in the effort. This "effort" part is what is in my opinion biggest different, Eastern Europe schooling required you to put in a lot of work, if you were talented you didn't need to use so much time, but if you weren't natural at math, you had to put in plenty of hours to get decent grades. Problems usually were not of the sort that can't be learned through "brute force".

I've done some teaching on the side and when I was teaching a guy in a "US" school for children of diplomats, difference was that their problems were usually much more freeform and required deeper understanding but once understood, used primitive math or physics methods. Our normal schooling was different, it used advanced math or physics but the problems were often times many variants of the same problem (which allowed for brute force learning). Honestly I think that it would be the best to have both, as many of my fellow students did not really understand the material we studied but they could brute force it.

saberdancer··on Embarrassed by your Olympic javelin: did cavemen do it better? (2012)
It's not really an outlier, there are plenty of sports where there are long standing world records, some of them have been broken recently but stood for a long time. It's just the nature of having so many sports, not every sport will attract as much talent resulting in having a much bigger impact when that world class talent appears (Zelezny). Usually these sports are technical in nature and thus harder to dominate through sheer improvement in nutrition and muscle power.

Take for example Usain Bolt, he competed in the sprint but if he focused his career on some other less popular athletic sport he probably could have been WR holder there as well.

If you combine this with the fact that it's possible there was more doping in the past (especially 80s), you can get these incredible world records that stand for decades.

saberdancer··on Where are the robotic bricklayers?
These are prefab houses. They are built in factory and then pieced together on site. What the poster was asking for was free/cheap plans to build a house, without support.

Kind of like open source design of a house.

saberdancer··on It’s not a self-driving car unless you can sleep in it
My car has level 2 (ACC with steering) and I've found that the whole process is extremely stressful and hard for me. Initial problem was that I did not trust the car to actively steer, brake and accelerate while keeping me centered in the lane.

After a while that wore off but you still had to be hyper vigilant as the system can "fail" at any moment and you need to be in control immediately. I find it harder to do than regular driving as in level 2 you need to "drive" and pay attention to whether the system has stopped working properly or not.

It's an incredibly frustrating. I'm surprised people buy cars just for this capability. I love safety systems but this is just a disaster waiting to happen.

saberdancer··on It’s not a self-driving car unless you can sleep in it
You can assume that the taxi driver will be able to react to most possible events on your ride home. Right now self driving systems require active oversight and you can't sleep while you use them.

It's like comparing an experienced driver (taxi or not) and a student driver. I'd sleep with an experienced driver driving but I wouldn't even think about sleeping if I am being driven by a student driver.

saberdancer··on THW: Germany′s army of volunteers for disaster relief
What I feel makes it confusing is that it is not clear how you can have 10 years of volunteer firefighting at the age when you are eligible for mandatory military service.

I believe that the other commenters said that you could "commit" to being a volunteer for 10 years and thus could avoid mandatory military service. This is the part that was not clear.

saberdancer··on I had to give a wrong answer to get the job (2017)
We are trained to answer quickly, people find silence uncomfortable (except with close friends).

Just pausing and not answering quickly when given an offer is a power move. I know it consciously but I still find it hard/impossible to do in real life.

saberdancer··on Bouba/Kiki Effect
My guess is that the shape of our mouth/tongue makes us choose "bouba" for the rounded shape.
saberdancer··on Beyond “Fermi’s Paradox” XVI: What Is the “Dark Forest” Hypothesis?
We are early in our "Space age". It's possible that inexperienced civilizations emit their position only to start hiding after realizing the dangers. Other possibility is that we are in a short period until we are wiped out because we broadcast our position.

All of this would drastically reduce number of visible civilizations at any time making the detection of civilizations much less likely.

saberdancer··on My take on the study from MIT that predicts “societal collapse”
My takeaway was that Earth as a system has operated outside of these temperatures and did not result in a runaway effect.

This means that there are self correcting systems that allow Earth to be relatively stable and life bearing for billions of years.

My first thought is that with increase in temperature, you get an increase in plant life which reduces CO2 levels resulting in lower temperatures and less plant life.

saberdancer··on In 1850, Ignaz Semmelweis saved lives with three words: wash your hands (2015)
Your recollection does not match my recollection.

From what I remember, initially they were saying masks are not useful to protect against disease because of various different reasons. Some of them were that general public would not wear masks properly and it would lead to increase in touching your face.

This "anti mask" approach was there until they managed to get enough masks, then changing their guidelines to include masks or even mandate masks. This was publicly admitted.

In my opinion, this whole process was a big mistake as it led to confusion and increase in public distrust of the health officials. How can you suggests masks don't work then change it to masks work but we had to keep them for ourselves.

Second problem is how does the mask not work if the virus spreads through droplets - if masks don't work then it is spread as an aerosol which was initially dismissed.
