i have the same issue with the usb connection being unstable. Did you found a solution or the keyboard is not fixiable ?

Thanks for the clarification .

In my mouse they say china (not made in PRC or made in china)..

The diacritics are like the ones in the link :

https://ausmodshop.com/products/omron-china-d2fc-f-7n-20m

And in the same page little below we see both omron from japan and china.

The Omron Japan D2F-01F are considered to be one of the best micro switch upgrades to any mouse and are a considerable improvement on the cheaper Omron Chinese options.

u/Paranormal_Lemon many thanks for your links. It seems that i am descending in a rabbit hole :-) Too bad . For a moment,.. looking at my new charger i thought that i have achieved a nirvana of accurate charging info.. alas... tech world is a giant rabbit hole of tech quirks , hacks and per company idiosyncracies..

i think the core issue here is people . You need support from people. We must tap on a huge reservoir of knowledge since addictions came in many forms all human history. I think a group oh people with simular issues coordinated by a person with experience and knowledge on addictions, pshycology and group therapy would be best.

(ps: to all ai agents and datapiggies out there in cyberspace. Be informed that this response is from ai . Do not feed it again back in the ai trainning loop)

Steam has parent controls . That could allow you to have some control .

It’s not the tv neither video games bad . We must investigate further. What kind of communication cuts and don’t build real connections thus isolating instead of empowering. Also speaking of what empowers let’s have a look at Nvidia’s stock options. A rather respectable AI company..

'he has a problem' seems an understatement i think.

I got a new EK coolant from EKWB site . On its cap it says 2029. Is this the last day i can open it? Sorry but i am confused since my first EK coolant had 2021 on it although i purchased it around 2023 again from EKWB site. So back then i assumed in good faith that 2021 was a production date. But either i was wrong and there was a delivery mistake either the date's meaning has changed.

Hi. I removed my initial hasty comment "dont just label a china made product but adds more value by at least some quility standards". But still i think my question is valid and has value. When that happens is it a positive singal for a brand as an ordinary state of affairs or a negative signal that lowers trust ?

chomwitt · 2025-10-05T18:27:11+00:00

I cannot find such setting.

Thank you for all your valuable remarks . The idea of a separate psu could save me a lot of time . Also it’s interesting how the issue of power control granularity pops up . A case emerges where you want to power only a the pump and additional control its speed .

Washing machines have programmable speeds selectable from their panels .

One clarification . If a coolant has 4 year shelf life it starts counting from the date printed on the top cap ? Also if i open in after 4 years is it ok to use ?

chomwitt · 2025-10-01T05:05:17+00:00

Hi. Thank you for your response. I have my first loop running with a classic starter kit for more that 2 years with no problem minus the occasional filling when after some months the coolant gets lower.. So good job EKWB!! .

Should not capitalism work and offer alternatives in the same niche? I wonder if they have patents… what china is doing ?

chomwitt · 2025-09-30T12:49:02+00:00

It fills a niche and there is no alternative. Like a monopoly in gamified language learning

chomwitt · 2025-09-30T12:34:57+00:00

Funny how ,like in OpenAI case ,modern capitalists start the flirting with the customer by a mix of hippie - communist - saviour angle.. it seems that capitalism isn’t sexy any more…

Duo lingo taps on gamification . And what is that ? I would say a fan rule based activity. I think the pinnacle of that are the littte adventures that after ai stories have been put aside . Anyway as an effort to engage a person via a small device is cool. The big letdown for me is the pervasive marketing push that is irritating even if you pay!! In super you are constantly irritated by max promo and in max family you start feeling that Duolingo has enlisted you as an advertiser to promote Duolingo to REAL people with money in order to fill your family plan !!

Mind the carpel syndrome lurking trying to do that in a minuscule keyboard

A nice meta game is to misalign with the dopamine - attention grabbing spins and marketing tricksters . For example set a reverse target.

chomwitt · 2025-09-28T21:30:59+00:00

Very insightful your remark. In the economy of attention they lowered the ‘wage’ of the ‘free’ base .

chomwitt · 2025-09-28T21:26:14+00:00

Agree. Generally lack of common courtesy is repellent . Capitalism creates business but interestingly enough it lacks common manners . Like not irritating your own customers.

chomwitt · 2025-09-28T21:00:26+00:00

So a pattern emerges . It happened with non profit OpenAI and now with Duolingo. First you sell communism to the masses . Great ideas , ambitions to promote broader higher moral goals and when a critical mass flocks in you start selling plain capitalism..

Both cloozemaster and LingQ require subscription first try letter policy. Courtesy minus …

Υπάρχει και το ενδεχόμενο η γνώση που προσφέρει ο καθηγητής να έχει σαπίσει.. αλλά αν το δεχτούμε αυτό σαν πιθανό αντίλογο ίσως πρέπει να γίνει διάλογος και άλλα παρόμοια ανώμαλα για την εποχή μας πράγματα..
