I'm a brother shill but a while back they experimented with a consumer-hostile firmware update for one of their models.

Since then, I've been edge blocking the rdns of update.brother.co.jp. It usually resolves to 4 IPv4 addys. Depending on the DNS resolver, they should lie in one of these subnets.

    3.164.143.0/24 # per asia dns
    13.249.98.0/24 # per us dns
    18.154.219.0/24 # can't recall
    18.155.68.0/24 # per alibaba dns
    18.160.225.0/24 # per he.net
edit: It looks like Brother is using cloudfront to provide CDN services. Every region I try I get a diff subnet. Better to query yourself than rely on my IPs.

Which model?

I’m also in Taipei. It’s the worst one ever I’ve felt in my life. Staying on the 7th floor with noway to escape in time is probably the worst feeling

As a Taiwanese, I got used to it.

I love hearing about these engineering challenges. Media loves to point to these design iterations as proof that the F-35 is over-hyped or inferior to existing jets. But what I see is innovation and trying new stuff. Sometimes failing, but in the end making an amazing jet.

I just kind of wish we lived in a world where we didn't NEED a new fighter jet and could instead invest this time and effort into peaceful pursuits.

Some would argue that arming oneself is the pursuit of peace.

Certainly, but I'd like to see the methodology of your experiments if you're able to say that a stimulant like coffee doesn't do anything, nor exercise. It might not do anything in the short term, but I dare you to drink 3x your daily coffee intake and see if you can't see any change, or to increase/quit your fitness routine and whether it doesn't do anything over a year.

I have tracked by BP over 50 kg of weight change, and BP correlates really nicely with fitness level, stress, etc. even though trends are visible over months, not hours.

There certainly are no quick fixes, apart from taking a BP pill (I take telmisartan+amlodipine, the latter replacing a diuretic that made me drier than the Sahara desert)

I was replying to another thread. I repeat here. My dad has hypertension due to [Conn's syndrome](https://en.wikipedia.org/wiki/Primary_aldosteronism). The only thing that helped tremendously was surgery.

You could of course argue that if he ate a ton of salt, his blood pressure would surge. But I wish he would've taken the surgery sooner rather than trying to out-diet and out-exercise his genetics as the diet/exercise had really small effect.

I suffer from hypertension (which pushed as high as 170/120) and went through a period where I was measuring my blood pressure many times a day to try to essentially hack what the problem was to try to find a natural solution.

What I learned is that, for me,

-salt intake had zero impact

-coffee had no impact

-stress level had almost no impact

-alcohol had no impact

-exercise / activity levels had no impact

The single and only controllable factor I could find, short of drugs, was that if I was cold my blood pressure spiked significantly. I had much higher BP in the winter than in the summer, and could improve it by wearing layers, gloves, etc.

My body decided to go full ham on blood pressure and it was destroying my kidneys. I would be constantly annoyed by the sound of my own heartbeat doing things like trying to sleep.

Telmisartan + Caduet (which is amolodipine + lipitor) and now my blood pressure averages 100/60. And courtesy of the lipitor my cholesterol and triglycerides dropped 60%, from high to normal. Many thanks to the very brilliant people who work in that field and developed those drugs.

Anyways, thanks for coming to my TED talk on the magic of modern medicine.

I've always felt one of the main reasons for this is that we never really got true microtransactions on the web. Pretty much all payment processors charge at least $0.20-30 per transaction.

My theory is that if there was a way to frictionlessly pay, say, $0.02 to access a piece of content ad-free, most people would be pretty okay with it. They key part is making the transaction frictionless - no more than 1-click/1000ms.

davidjytang · 2 years ago
If publisher accounts can be billed by the payment processor every month instead of every transaction and processor charges based on a percentage of monthly transaction.

I feel this is a business negotiation instead of a tech issue. But then I may be just clueless.

I speak Japanese and Spanish - when I went to Japan with my Mexican wife, she asked how to say "bread" in Japanese and I said "pan" and she said, "honey, you're mixing up your Japanese and your Spanish, that's the Spanish word for bread".
davidjytang · 2 years ago
Having gone through half a century of Japanese period, Taiwan also calls bread "pan".
