tdrdt··on Covid-19: Runny nose, headache, and fatigue are commonest symptoms of omicron
Note that this means a PCR-test will have no meaning other than you came in contact with Covid-19 somewhere between now and up to 3 months ago.

The PCR-test measures the existence of virus RNA. Not when you were infected, if you are sick of that virus and also not if you are contagious.

Because the symptoms are now similar to almost all other virus infections there is no way of knowing if you are sick of Omicron after a positive PCR-test.

Edit: For some confused people an example. You came in contact with Omicron but didn't get sick of it. 2 weeks later you came in contact with the RS virus and this time you got a runny nose so you get a PCR-test. The result is positive from the Omicron contact 2 weeks earlier. So they say you are sick of Omicron. But in fact you are sick of RS.

tdrdt··on Ask HN: I've lost faith in myself as a developer, how do I get it back?
Can be anything.

But from my own experience: it might have to do with lack of energy.

It sounds like you are responsible for the decisions you make. If you don't have a lot of energy you don't have energy to deal with possible bad outcomes. That's when you start to overthink your decisions to protect you from energy loss in case you made the wrong choice.

So check your energy levels.

And if the responsibility is too much for you be honest about it. Involve others to make the decision.

tdrdt··on Web3 is going just great
I'm into webdevelopment since 1999 but I still don't know what web2 is.

As a matter of fact the internet did not change that much as most people think. Ofcourse CSS changed and made things easier, Javascript is making application development more easy but in the end we are still transferring text and media.

Maybe the biggest change came when browser plugins started listening to http traffic. The change to https was one of the fastest on the internet and right now almost all our interactions on the web are 'secure'.

While I think blockchain tech is in some sense a new idea, I don't think it will change the internet very soon. I think it will come as soon as ipv6.

tdrdt··on Arkansas waitress fired after getting $4,400 tip
Maybe you are not aware of this but the vaccines don't prevent the spreading of the virus. This is because they prevent you from becoming sick, not from becoming infected or being contagious.

And after 6 months the effect of the vaccines starts declining and after 9 months they don't work anymore. That's why booster campaigns are starting now.

tdrdt··on Italy fines Amazon record $1.3B for abuse of market dominance
Am I right that this is (only) about unfair dominance in logistics? It looks like Amazon Prime is forcing sellers on Amazon to use Amazon logistics and thus putting others out of business.
tdrdt··on Pfizer and Biontech provide update on Omicron variant
Focus on case numbers by means of PCR tests is problematic because a PCR test only measures virus RNA, not the cause of sickness or contagiousness.

If a thousand healthy people come in contact with the virus it is possible they all will have a positive PCR test while not being contagious at the same time.

tdrdt··on Ikea Vindriktning Air Quality Sensor Review and Accuracy
The brand is Simr, but I think there are only 3 or 4 meters that are sold as whitelabel and rebranded a thousand times. I think it was around $30.

Outside it measures around 400ppm so the base point is good. Inside it measures 480ppm with good ventilation. When someone farts it goes to 2000ppm for a while. So I think it measures 'alright'.

tdrdt··on Ikea Vindriktning Air Quality Sensor Review and Accuracy
Exactly. Recently I bought a very cheap CO2 meter. It is inaccurate, but still accurate enough for 99% of the people.
tdrdt··on Estonian winter 1, delivery robots 0
Maybe the snow came by surprise.

There have been a lot of sudden snow lately. In the UK 50 people were stuck in a bar and I believe in Denmark people had to stay the night in IKEA.

tdrdt··on Blender 3.0
I have been using Blender for over 15 years and I also love it but also for different reasons.

When I started using Blender I came from 3DsMax. Max took almost half aminute to start, Blender maybe 2 seconds. And now, years later, Blender is still fast. The architecture is just very good. And maybe it's one of the best in the wold.

A lot of people hated the UI, but I always loved it. I love that you can arrange the panels the way you like. I wish programs like Photoshop could do this as well. And yes, since v2.8 everything became even better and the learning curve was lowered.

I also love all shortcuts and user interactions. This was really made for users. And maybe that's because Blender is mostly made by users.

And now v3.0! I am excited about two things: Cycles X (very fast rendering) and the overhauled Geometry Nodes.

I believe Geometry Nodes are the next big thing because this is Blender's answer to Houdini.

Edit: if you are interested in Geometry Nodes you should check out Erindale @ YT https://youtube.com/c/Erindale

He creates complete scenes without modeling a thing. The models are all procedurally built.

tdrdt··on Townscaper Running in the Browser
Ah thank you. I was in fact looking for that talk!

What I really like about this is that the base grid is not straight. Therefore the buildings are arranged in a very European style.

Here a very interesting talk by Oskar Stålberg where he explains how this works: https://youtu.be/1hqt8JkYRdI

It is running in Firefox on mobile just fine while I don't have a high end smartphone.
tdrdt··on Researchers shrink camera to the size of a salt grain
If you take a look at the paper it is only about the optics. Which is still a big achievement, but I think the complete system is a little bit bigger than a grain of salt. So the article should be taken with a grain of salt as well.

tdrdt··on Arctic Ocean started getting warmer decades earlier than we thought
Well lets say natural global warming will cause a rise of 5°C in the next 50 years. Then we have 50 years to adapt. But when we accelerate this change we might need to adapt in 5 years. And we might even cause a rise of 6°C instead of 5. I believe those are the big problems we are facing.
tdrdt··on Arctic Ocean started getting warmer decades earlier than we thought
Do you agree?

Absolutely!

I think we are very 'unlucky' (stupid) that we are accelerating a natural climate change that causes global warming.

tdrdt··on Arctic Ocean started getting warmer decades earlier than we thought
Personally I am still not convinced climate change is completely caused by human activity. But I think we are accelerating a natural climate change.

“Climate simulations generally do not reproduce this kind of warming in the Arctic Ocean, meaning there’s an incomplete understanding of the mechanisms driving Atlantification,”

My takeaway: because we still know so little about the mechanisms we should be more careful about our environment. It's very naive to pump tons of CO2 into the atmosphere without knowing what will happen.

The problem is that since the sixties scientists are predicting doom and this is causing people to become skeptical about new insights.

For example, after decades of sea level doom scenario's people are saying it is "slower than expected".

tdrdt··on Disney Combines CGI with Neural Rendering to Tackle the ‘Uncanny Valley’
I once talked to a painter who painted stunning portraits. He said that it took him less than a day to paint the portrait but then days to make the eyes and mouth believable.
tdrdt··on Could One Shot Kill the Flu?
I think this is the right answer. Like Corona it mutates too fast. So you need to vaccinate all living creatures that can transmit the virus all at the same time.

Another way to get rid of it is to go into a global 100% lockdown for two weeks at the same time. Again animals that can transmit it included.

tdrdt··on Fleet, a Lightweight IDE from JetBrains
To me it sounds like this is used to test a rewrite of all their IDEs because it is written from scratch.

I can imagine if this becomes a succes they will update all their IDEs or use Fleet as the new platform.

tdrdt··on Fleet, a Lightweight IDE from JetBrains
That's strange. When I open a 1m+ LoC in Rider it takes around 2GB of RAM [1] but is still very workable. Ofcourse it is not extremely fast but I am always impressed this even works with all the code hints, indexed code and what not.

By the way, sometimes a corrupted cache can be a problem. You can fix this via File -> Invalidate Caches.

tdrdt··on My friends Instagram was hacked and deep-fake videos posted in less than 6 hours
Doesn't this apply to the whole internet? Internet connects both good and bad people.

The moment you create something that can be used to upload any type of content, some people will exploit it.

tdrdt··on 90% of Black Friday deals were the same price or cheaper six months before
Most of those discounts are based on the advice price. And the advice price is a max selling price estimated by the supplier.
tdrdt··on PHP 8.1.0
I use C#, Javascript and PHP a lot.

PHP always wins when it comes to deployment and productivity. In my opinion that's the power of PHP.

It's also versatile. I used it for small projects, multi-million € projects, COM-port communication, API communication, prototyping and what not.

The syntax is not great, but to me PHP is this multi-tool that just gets the job done and will run reliable for years.

tdrdt··on In major shift, EU says vaccine boosters should be considered for all adults
They mutate 2 gnomes/month.

So we already have thousands of mutations. But changes we call variants happen much slower.

Still, the vaccins are based on the 2019 variant.

tdrdt··on Tracking Crucial Metrics of Earth's Global Warming
I think the point parent is making is that it is possible to cherrypick a reference period.

You can say that the melting of glaciers is an anomaly but when an ancient forest appears below the melted glacier how can we agree on what an anomaly is?

I don't want to deny global warming but I agree with the parent that it's difficult to state what an anomaly is.

Does anyone know why the change at the north pole is bigger than the south pole? Is this because the north pole is floating on water?
tdrdt··on What it's like to ride 900 km in a day
I never use a GPS.

But this was a long time ago. I think somewhere around Metz. The road was something like a primary road which turned into a highway. A paper map indeed confirmed the road changed into a highway.
