Thx, my wife liked them too, I’m not a huge fan but they came with the house :)

Yeah, that sounds like an idea, but don’t you think that it might be too elastic? I have never used this glue.
- Comment on Broken stair step 3 days ago:
I added a new picture showing how much broke off. This is no simple re-gluing unfortunately.
- Comment on Broken stair step 3 days ago:
Thanks a lot for your reply! I’m not sure if I get it though. I attached another picture to my post that shows the step from the top. The part missing is a lot of material, I’m not sure how breaking everything up and glueing the tiles back should work. I’m confident that I could somehow model the little structure using some goey material and then glue the tiles back and apply grout but I’m not sure about the stability of this.
i could also just glue the whole block back in place using 2k glue or cement.

Maybe use a release and not a weekly build?
- Comment on After 3 prototypes and several motors I finally got this cat toy motorized, still pretty loud though I wonder if I can dampen the gearbox somehow 2 weeks ago:
Look into BLDCs maybe the ones for gimbals as you need very low rpm.

I’m not the designer of this. I’ve also wondered. Maybe it’s just a practical choice to have something tough to attach your wires to.

Not sure what MH is but in bigger systems magnetically coupled centrifugal pumps are used afaik.
- Comment on DIY experimental Redox Flow Battery kit 1 month ago:
The roadmap defines 3 milestone batteries. The first is released, it’s a benchtop device that you can relatively easily build on your own. It has an electrode side of 2 x 2cm2. It does not store any significant amount of energy. The second one is being developed right now, it has a cell the size of a small 3d printer bed (20x20cm) and will also not store practical amounts of energy. It will hopefully prove though that they are on the right track and that they can scale it up. The third battery only will store significant amounts of energy but in only due end of the year (probably later).
Current Vanadium systems cost approx. 300-600$/kWh according to some random website I found. The goal of this project is to spread the knowledge about Redox Flow Batteries and in the medium term only make them commercially viable.
The aniolyth and catholyth are based on the Zink-Iodine system in an aqueous solution. There are a bunch of other systems though, each with their trade offs. The anode and cathode are both graphite felt in the case of the dev kit.

You need Polypropylen filament for printing, graphite felt as electrode, grafoil gasket material as bipolar plate, brass plate as current collector (cut by cnc), silicone gasket material and a measurment device like a potentiostat.

Don’t recommend using FTP. It’s a shitty old protocol that needs to die. Just use nginx or apache with directory listing enabled.
- Comment on YSK that apart from not having a car, the single greatest thing you can do for the climate is simply eating less red meat 2 months ago:
If you don’t consent to being born into this world right now, would that not mean that you should just kill yourself? I off course don’t mean to say that you should, but I’m curious why you have a drive to live, and thereby consuming precious resources that could benefit less defeatist people. Or would you have chosen differently if you had been asked when you were born.
I understand that we seem to be in a global situation where imminent doom is unavoidable but maybe you should ask older people or read up, because I think these things happen on a regular basis.
And no, I don’t want to downplay the consequences of the multiple clusterfuck of global catastrophes we’re heading into (since a long time). Maybe I’m just a hopeless optimist :).

No, I rarely read the code of software I use, especially crypto code since thant’s not my thing. But good to know that you did. Thanks for your opinion.

- Comment on How to harden against SSH brute-forcing? 5 months ago:
Welcome to the internet! Your system will get probed. Make sure you run as little as possible services on open ports and only high quality ones such as OpenSSH. Don’t freak out because of your logs. You’re fine as long as your system is up to date and password login disabled! Don’t listen to the fail2ban or VPN crowd. Those are only snake oil.
A VPN is probably just as (in)secure as OpenSSH. There is no gain in complicating things. OpenSSH is probably one of the most well tested code for security around.

Cookie banners are not mandated by GDPR. It’s an unrelated piece of law.

Wafs don’t make you safer but create unnecessary attack surface. Just keep your machine and services up to date.

Argh, hate them!
- Comment on FuckYourHeadlights - A community for people to organise and vent about ridiculously bright lights 6 months ago:
I’m from Europe and headlights suck here too! It’s spectrum of LEDs and tall cars and probably bad regulations too.
- Comment on FuckYourHeadlights - A community for people to organise and vent about ridiculously bright lights 6 months ago:
My problem is that I drive a low car (Ford fiesta) and most other cars are taller, this makes them way more blinding.
- Comment on FuckYourHeadlights - A community for people to organise and vent about ridiculously bright lights 6 months ago:
What I currently do is to take out my own headlight from its holder and deliberately point into their eyes. At least the message should be clear.
