Google Shenanigans

For years it has been a common theme among programmers that Google's search results have changed for the worse. It feels like the suggestions are becoming less and less applicable over time. Today, I spotted one of the worst cases that I have seen so far when searching for a documentary called "Flatten the Curve Flat Earth" (2022). This documentary is about flattening the curve of the earth and has nothing to do with medicine. However, Google automatically interprets it as a kind of medical statement:  Notice especially the second search result where "m...

The X Community Notes Are Different, Are They?

In some cases, Wikipedia feels the need to "clarify" a certain video, which a commenter aptly called the "the blue box of gaslighting":  Now X community notes was promised to be something else, but to me it does look very similar. The note posts some helpful "context":  The reason that I'm critical is that especially on a topic like this, the note doesn't add any information. People who believe that the moon landing was staged will still believe that a...

Making IPv6 work with Caddy and Hetzner

After a few hours of fiddling, this site is now properly accessible via IPv6. My configuration uses Caddy as the reverse proxy meaning that it forwards the requests to the right service based on the `Host` that the browser specifies. Thanks to this, one server can host hundreds if not thousands of websites from one IP. In my Caddyfile, I had specified the following ```caddyfile www.huijzer.xyz { redir https://huijzer.xyz permanent } huijzer.xyz { reverse_proxy 127.0.0.1:3000 } ``` And then I thought that for IPv6 maybe this last part should have been ```caddyfile huijzer.xyz { reverse_p...

Do Not Put Your Site Behind Cloudflare if You Don't Need To

At the time of writing 12:43 UTC on Tue 18 Nov, Cloudflare has taken many sites down. I'm trying to browse the web, but about half of the sites show an error:  Most of these sites are not even that big. I expect maybe a few thousand visitors per month. This demonstrates again a simple fact: if you put your site behind a centralized service, then this service is a single point of failure. Even large established companies make mistakes and can go down. Most people use Cloudflare because they have been scared into the idea that you need DDoS protecti...

Generating an SSH key for a webserver

Assuming you have the SSH password for a webserver called say `case` and email `[email protected]`, you can generate a key as follows: ``` ssh-keygen -t rsa -b 4096 -C "[email protected]" -f ~/.ssh/case ``` Next, add the server, which has say username `user` at location `case.example.com`, to your `~/.ssh/config`: ``` Host case HostName case.example.com User user IdentityFile ~/.ssh/case ``` Then you can copy this key to the server ``` ssh-copy-id -i ~/.ssh/case [email protected] ``` and afterwards log in with ``` ssh case ```

Ondernemer op Reddit over subsidies

> De enige vorm van “subsidie” die ik als ondernemer concreet ervaar, zijn de belastingen die ik betaal. Het lijkt – en ik zeg nadrukkelijk lijkt – alsof je reactie komt vanuit een positie waarin men niet hoeft te dragen wat ondernemers dagelijks moeten dragen. Zonder een gezond bedrijfsleven bestaat er geen economische ruimte voor sociale voorzieningen of luxe waar we als samenleving allemaal van profiteren. > > Ik zeg niet dat vermogenden nóg rijker moeten worden, maar ik kan je verzekeren dat het tegenwoordig voor veel ondernemers, zelfs met een goedlopend bedrijf, buitengewoon moe...

Some Thoughts on High Frequency Currents and Oxidative Stres...

s As I wrote before, there is much research that shows that electromagnetic radiation causes oxidative stress. This means that electromagnetic radiation can knock an electron out of a molecule, which is called ionizing radiation. Some people say that electromagnetic radiation from radio frequencies is non-ionizing, but this contradicts the fact that many studies have shown that radio frequencies also produce oxidative stress. The higher the frequency, the more ionizing (read: damaging) the radiation is. Similarly, it is known that x-rays at wavelengths below 10 nm will destroy cells. Electro...

Cell and DNA Damage and Repair from Different Kinds of Radia...

tion A very interesting fact from the book _Light: The Medicine of the Future_ (1990) by Jacob Liberman is that far-ultraviolet radiation (UV-C), 100-280 nm, causes DNA damage and shortens cells' life spans, according to a study by Dr. Smith-Sonneborn. However, she found that near-ultraviolet radiation (UV-A), 320-400 nm, repaired cells and reverses aging. Even more, it repairs DNA while damaged DNA is known to cause cancer. This suggests that sunlight can repair cells and reverse aging since sunlight that reaches the earth is mostly above 270 nm, according to Wikipedia: !spectrum of solar...

Solar Cell Spectral Sensitivity

I just came across the book _Solar Secrets_ (2014) by Peter Lindemann. It observes that most solar panels are optimized to perform on bright sunny days whereas they barely perform on cloudy days. This while there are panels that capture light of lower wavelengths and are therefore much less affected by clouds. The author shows this in the following figure from page 17:  Here it can be seen that Amorphous Silicon (a-Si) solar panels produce energy from the 500 to 700 nm wave length range while Crystalline...

AI Crawler Mitigation via a Few Lines of Caddy

To mitigate AI crawlers, simply require a bit of Javascript: ```caddy domain.com { # Match all requests without a "verified" cookie" @unverified not header Cookie *verified* # Serve them a JS page that sets the cookie handle @unverified { header Content-Type text/html respond <<EOF EOF 418 } # Handle all other requests normally reverse_proxy localhost:3001 } ``` This works because these crawlers have disabl...

On Pearl Powder

I've seen freshwater pearl powder being presented as healthy primarily due to it being a natural source of various minerals. Although the sales talk sounded convincing, it's probably good to verify the claims. Pearl powder is part of traditional Chinese medicine and was mentioned in the _Hai Yao Ben Cao_. First of, freshwater pearl powder contains primarily calcium carbonate (CaCO₃) and magnesium carbonate, and some proteins, glycoproteins, and polysaccharides (Loh et al., 2021; Latire et al., 2017). Pearls according to a test with a spectrometer also contains 0.2% natrium, 0.04% manganese,...

On the Health Effects of Electromagnetic Radiation

We've all seen or heard people who claim that electromagnetic radiation has negative health effects. I decided to look into the scientific literature to see whether the claims are true and if yes what health effects one could expect. The search is a preliminary one so it will not be particularly structured. As a start, Wikipedia makes an interesting claim on the non-ionizing radiation page. The article writes that: > Non-ionizing (or non-ionising) radiation refers to any type of electromagnetic radiation that does not carry enough energy per quantum (photon energy) to ionize atoms or molecul...

A new description for the YouTube Wikipedia "fact checking"

In a YouTube comment, someone gave a great description for the Wikipedia fact-checking:  The correct description for this "context" is "the blue box of gaslighting". In general, the word "context" visible above the box is also misleading since providing "context" is often an euphemism for lying. Brought you to by a comment below a AwakenWithJP video.

What to do to understand the Western world

If you want to understand the Western world, just read the scriptures of the three main religions. Even when you are not religious that **DOES NOT MEAN** other people are also not religious. Billions of people read these scriptures weekly if not daily. They explain 90% of what's happening. I'm often reading books where some author put in countless hours of research to figure out a certain event, and while I'm reading it and can't help but notice that it's often exactly in accordance with the religious beliefs of the subject.

Companies are Lying About AI Layoffs

Companies are saying that the economy and AI are causing the large amount of tech layoffs, but Vanessa Wingårdh looked at the H-1B visa data and noticed that the companies are lying. She argues that the American employees are being replaced by cheaper H-1B visa workers. WSJ also reported on this due to some senators speaking up. As proof she uses the H-1B data from the U.S. Citizenship and Immigration Services. When filtering by fiscal years 2023, 2024 and 2025, the number of Beneficiaries Approved for some of the big corporations as of 30 June 2025 are shown in the second column below. I al...

Wolves in the Netherlands

In the Netherlands, we currently have about 100 wolves walking around. Politicians say this is a "natural phenomenon" and that they walked here from their own volition. Meanwhile animals in rural areas are being killed by these wolves and even a runner has been attacked, while the government forbids the shooting of them because they want to first "establish a healthy state of conservation." The media is now even informing people about how to spot the difference between a wolf and a dog. Various other groups question the theory since the Netherlands is a tiny country which no real large swaths...
