This is exactly what has been playing out in the Netherlands the past couple of months: the weather institute (KNMI) released their own weather app that is functionally the same (in some cases superior) as the commercial apps that want your consent to track and serve ads.

The commercial parties sued KNMI, even though they use the public data provided by KNMI. Luckily they lost: https://www.dutchnews.nl/2025/02/knmi-weathers-legal-app-sto...

And as a bonus, there was some Streisand Effect when this was in the news, and people have been moving to the KNMI app in droves.

I'm still not quite sure how to take this, does this mean that:

We can not fix problematic netcode (this is a running joke in the TF2 comminity)

We can fix game balance issues (that could also be fixed through configs)?

I've been using it for about a year now and for personal stuff its fine. Just some sheets and the occasional document and there haven't been any issues with formatting and such that tend to pop up when moving between MS and others. It runs with a single window too, where all docs and sheets are open, I like that.

My pixel 4a lasted about 3 hours before the update, now its about an hour. Even with the discount in the store, it was cheaper to get the pixel 8a and some cash from a local vendor. The ticket to get the reimbursement went surprisingly fast, still waiting on money though.

Yesterday I got my new 8a, installed grapheneos and it works very well! So far no massive issues. When I tried this on the 4a some years ago, netflix complained about general certificate stuff and casting was broken, microG et al was barely holding on. Now, no problems at all!

I play one game at a time for about a month and then move to the next. When I first played Mario Odyssey on my switch I was over the moon with how much pure fun it was compared to all the good looking and serious RPGs I played in the decade before. I had forgotten games can be this enjoyable. Nowadays I try to do these super fun games in between my souls-like sessions.

I got to visit the telescope earlier this year, its pretty cool. In a forest outside some small towns. For how well connected the Netherlands is, its pretty hard to reach.

We looked at the sun and some planets in radio frequencies (its all radio astronomy with LOFAR nearby).

That they can listen to Voyager with such an old instrument is incredible. It must help that the satellite is aimed at us.

I bought a dumb tv some 2 years ago. 4k, 50ish inch and it has a chromecast v2 attached. Works great.

The funny part is when younger family members come over, they get frustrated there's no netflix button on the remote! Last time that lead to a drawing sessions instead of some paw patrol nonsense.

About a month ago I would've said the automatic upgrades. But a few weeks ago I tried to upgrade, my custom setup couldnt be resolved by the image builder (probably old software installed). I decided to backup, export the uci commands too and do a clean install. Setting up was super easy from the uci commands and it turns out the rest of my setup was not essential.

Then I had to join a vlan for my new ISP. That was a tough one! Evenings of reading threads and going through documentation and there was no clear answer. In the end I asked an LLM and the instructions were so easy, it made me wonder how I missed it.

So I would join some other calls in here for common setups.

What they don't tell you is that if you write out all the indices (mu and nu represent 4 spacetime coordinates, antisymmetric components (f_abc = -f_bac, etc), the kappas and lambdas I don't even remember!), and their contractions [1], this giant equation becomes a few times larger than its current form.

Physicists like to contract and shorten everything, and while it is fun, you need a dictionary of rules and conventions to write out the full form.

Luckily there are many tricks to use in these shorter representations, but one tends to forget the incredible amount of information within them.

I was just thinking about the distances used: in LIGO/VIRGO, the sizes of the chambers is 4 km, and the interferometric distance they look for is 10^{-18} m to detect a GW.

For the baseline of DUNE we have 1300km, so that would mean 10^{-15} m if we do a very simple comparison. (I am not that familiar with GW detection!).

Measuring neutrino events at such a resolution would seems not realistic currently, as most detector measure events at sizes of cm (reactor experiments)- to meters (atmospheric / galactic). However, don't discount someone coming up with a brilliant insight to actually do this measurement. Some things we measure today were thought impossible not that long ago, like GWs and the Event Horizon black hole image.

This is the dream of multi-messenger astronomy:

Simulations show that next generation gravitational wave detectors will be able to detect the initial part of the wave before the actual merger of objects (or collision?). If you can identify this signal in time, you could make the 'regular' telescopes look into that particular direction and look for a signal in light, and you could use a neutrino detector at the same time (think IceCube, KM3NeT, Baikal and others that look at large parts of the sky) to look in the neutrino channel.

This way you would have gravitational wave-, light- and neutrino-channels from a single object. This is still many years (decades?) away, but would be incredible for studying exotic objects.

If you mean, measuring the neutrino baseline difference when a GW passes through the Earth, perhaps. I never thought about it, but its definitely intriguing.
