rsync··on Cloudflare Email Service: private beta
Hosting your own email means the subpoena (or warrant) is delivered to you.

You get to respond to requests and your data cannot be handed over without your knowledge.

rsync··on EU age verification app not planning desktop support
Can you expand on:

"It has interesting permissions as well ..." ?

I assume a banking app needs (temporary) permission to use the camera for check photos or things of that nature ... and possibly (temporary) use of location data.

I would be alarmed if it requested microphone or access to either contacts or photo storage ...

rsync··on Privacy and Security Risks in the eSIM Ecosystem [pdf]
"Install phone company app ..."

You've already lost me there.

I don't install the samsung dishwasher app or the mcdonalds value points app or the Mountain Dew summer of fun app ... why would I install some random national carrier telco app ?

rsync··on OpenAI and Nvidia announce partnership to deploy 10GW of Nvidia systems
"In accounting terms, this is a shady business practice known as "round tripping" where you invest in a company for the sole purpose of them buying your product. It allows you to count your revenue multiple times."

... and we've seen this before in previous bubbles ...

rsync··on FLX1s phone is launched
"I think the crucial issue here is Android app compatibility ..."

I thought there was a robust android emulator for linux such that I could run android apps - and call an Uber or whatever - from desktop linux ...

Is that not so ?

rsync··on Are touchscreens in cars dangerous?
I think that touchscreens are dangerous in cars but I’m open-minded and can imagine implementations that wouldn’t be unsafe…

What I am absolutely convinced of is that touchscreens are cheap and tacky.

The current trend of so-called “luxury” cars with wrapping screens all the way around the passenger is terrible.

A high end, or luxury, car should have physical controls and physical dials/gauges.

I’m reminded of a quote I heard describing the then new Bentley SUV: “what a poor person thinks a rich person’s car looks like”.

rsync··on iTerm2 Web Browser
I want my terminal to be as simple, and dumb, as possible.

It should ignore unexpected inputs and formats. It should not know what a web page or an image file is.

It should have no idea what it is displaying nor what is happening on the remote end ... I don't want it to know I am more'ing or less'ing or paging, etc. Just show the output.

I feel so strongly about this that I am sometimes tempted to collapse output to ascii-256. I resist this temptation because I sometimes cut and paste foreign URLs ... which my terminal has no idea is a URL.

rsync··on Germany is not supporting ChatControl – blocking minority secured
Children shouldn’t have devices.

They certainly shouldn’t have always online devices capable of accessing social media platforms.

US father of three here and if they’re younger than 15 just hand them a Nintendo switch… if you hand them anything at all.

You will never win the arms race you’ll be fighting- against both your children and the platforms.

Just opt out.

rsync··on CPI for all items rises 0.4% in August, 2.9% YoY; shelter and food up
You are correct that this is confusing… one of these markets, broadly speaking, is wrong.

I think the bond market is betting on no rate cut and we are seeing early entrants into a larger flight to safety.

rsync··on CPI for all items rises 0.4% in August, 2.9% YoY; shelter and food up
ORCX exists …

I was very tempted by long dated puts on this when the intro-day high of +40% was reached…

rsync··on Browser Fingerprint Detector
"... so the fact alone that you're unique might potentially not matter if you're _differently_ unique every time you visit the site. Is there a flaw in this line of thinking?"

No, you're thinking correctly and the odd discourse that you (and I) see is based on two implicit assumptions:

1) Your threat model is a global observer that notices - and tracks and exploits - your supposed perfect per-request uniqueness.

2) Our browsers do not give us fine grained control over every observable value so if only one variable is randomized per request, that can be discarded and you are still identifiable by (insert collection of resolution and fan speed or mouse jiggle or whatever).

Item (1) I don't care about. I'd prefer per-hit uniqueness to what I have now.

Item (2) is a valid concern and speaks to the blunt and user-hostile tools available to us (browsers, that is) which barely rise to the level of any definition of "user agent" we might imagine.

I repeat: I would much prefer fully randomized per-request variables and I don't care how unique they are relative to other traffic. I care about how unique they are relative to my other requests. Unfortunately, I am wary of browser plug-ins and have no good way to build a trust model with the 12 different plug-ins this behavior would require. This is the fault of firefox and the bad decisions they continue to make.

rsync··on Dietary omega-3 polyunsaturated fatty acids as a protective factor of myopia
"... wow, not sure about avoiding cheese & milk - sounds risky for calcium/bones health ..."

A disappointing level of knowledge and sophistication in this late, 21st century era.

Your bone health is almost entirely correlated to the load bearing exercise and gravity stress that you put on your musculoskeletal system.

Fine optimizations to your diet (just like fine optimizations everywhere in life) are only sensible after you've taken care of the big, macro factors.

rsync··on I ditched Spotify and set up my own music stack
Genuinely curious…

Did you, in fact, rip your SACDs at their true, higher, resolution?

If so, how ?

rsync··on Airbus B612 Cockpit Font
Does the font change based on what the aircraft is doing?

I kid …

rsync··on Cloudflare Radar: AI Insights
"CF is trying to double dip: they are charging users for their CDN, and now they try to also charge for the privilege of accessing their user's content."

Don't forget that cloudflare provides service to the very botnets and flooders/booters they purport to protect against.

Would that be triple-dipping ? Or do we have a special term for this specific behavior ?

rsync··on We should have the ability to run any code we want on hardware we own
Just a nit …

As this is HN - a very thoughtful and technically astute demographic - it’s very unlikely that your parent, or others reading, own a “smart fridge”.

rsync··on Hardening Firefox – a checklist for improved browser privacy
A fools errand.

No matter how effective this list is, the settings will either revert, change, or be silently undone.

New settings will alter the efficacy of the old ones.

Existing settings will disappear.

The behavior you hoped to configure changed to its opposite.

Remember: there was one morning when we all woke up and saw every dns query sent to cloudflare doh by default, and with no opt-in.

rsync··on The web does not need gatekeepers: Cloudflare’s new “signed agents” pitch
“But the reality is how can someone small protect their blog or content from AI training bots?”

Why would you need to?

If your inability to assemble basic HTML forces you to adopt enormous, bloated frameworks that require two full cores of a cpu to render your post…

… or if you think your online missives are a step in the road to content creator riches …

… then I suppose I see the problem.

Otherwise there’s no problem.

rsync··on Ask HN: The government of my country blocked VPN access. What should I use?
Or, at least, that’s how it would work if it wasn’t for SNI…
rsync··on Paracetamol disrupts early embryogenesis by cell cycle inhibition
"Tylenol is very safe if taken as prescribed. The overdose amount is relatively low, but not uniquely low."

The issue is that the overdose of Paracetamol is relatively similar to the effective, or safe, dose:

"(overdose) of paracetamol is caused by taking more than the recommended maximum daily dose of paracetamol for healthy adults (three or four grams),[38] and can cause potentially fatal liver damage. A single dose should not exceed 1000 mg ..." [1]

See the problem ? A mere 3x the single dose puts one in "potentially fatal liver damage" territory.

This problem is compounded dramatically in small children where errors in the estimation of the child's weight can put you half way to overdose before you even start. Now add a meniscus error as you fill a clear plastic cup in the middle of the night ... or Mom gives a dose at 5am without knowing that Dad already gave a dose at 2am ... ugh.

Compare this to Aspirin where the overdose is as high as 15-30x the effective dose.

rsync··on A German ISP changed their DNS to block my website
Tangent: does anybody know which DNS server software that providers like dns4eu and nextdns use ?

Are they using nsd or bind or … did they write their own?

rsync··on Exploring EXIF (2023)

  magick convert IMG_1111.HEIC -strip -quality 87 -shave 10x10 -resize 91% -attenuate 1.1 +noise Uniform out.jpg
This will strip ALL exif metadata, change the quality, shave 10 pixels off each edge just because, resize to xx%, attenuate, and adds noise of type "Uniform".

Some additional notes:

- attenuate needs to come before the +noise switch in the command line

- the worse the jpeg quality figure, the harder it is to detect image modifications[1]

- resize percentage can be a real number - so 91.5% or 92.1% ...

rsync··on Seagate spins up a raid on a counterfeit hard drive workshop
It’s not that Chia is more intensive than any other high usage activity…

Rather, it is a combination of a highly intensive use case and a relatively morally bankrupt user base that results in a supply chain full of burned out SSDs.

I say relatively morally bankrupt… I am sure there are many delightful people out there mining Chia coin …

rsync··on Toothpaste made with keratin may protect and repair damaged teeth: study
Strange to see this at 246 points on the front page and no mention of bioglass such as novamin?

Is this mechanism different?

rsync··on Seagate spins up a raid on a counterfeit hard drive workshop
The supply chain - especially for SSDs - is full of old parts being sold as new:

https://kozubik.com/items/MaestroTechnology/

... some vendors have been found tampering with SMART data which can be done on certain models ...

In the post-chia[1] landscape, I would advise extreme caution in sourcing drives and a decent shortcut is to not buy from Amazon ...

"... the hacker subculture was intelligence influenced all the way down ..."

Oh stop.

There was zero intelligence at any of the five CuervoCons ...

rsync··on Enlisting in the Fight Against Link Rot
I run a public URL shorter and you are correct:

it is relatively simple and inexpensive to operate and there is no reason it can’t continue operating into the indefinite future.

I disagree with the op on one major point… They suggest that the proper way for a service like this to operate is with a public database of links…

However, when I think of all of the different ways, one might use a shorter, it seems obvious that many links would necessarily be sensitive and/or private.

Therefore, I consider myself to have a dual mandate: privacy of the links created, and a duty, that I have assumed, of running the service for decades.

rsync··on The surprise deprecation of GPT-4o for ChatGPT consumers
Can you elaborate?

Is this ID requirement for non-US persons?

What if the account is a corporate or a business account? Whose ID would you use?

rsync··on How to sell if your user is not the buyer
"Give them the best possible chance at convincing the leadership. Make them look awesome for even bothering the leadership with a choice like this."

We made a "CEO Page" for this purpose:

rsync··on Why Exercise Is a Miracle Drug
"We have ostensibly spent much of our evolutionary budget on the ability to run ~indefinitely no matter what."

This appears to be the case and this idea is explained, in-depth, in the excellent book:

_Born to Run_

... by Christopher McDougall.

I highly recommend it.
