The workarounds on this page mostly suggest to use large public resolvers. Feature request (not sure if the author is on HN): it would be interesting to know which domains are blocked by 9.9.9.9, 1.1.1.1, and especially the new DNS4EU service.

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?

  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% ...

Is Chia particularly harder on drives then other typical uses? Speaking as someone who wouldn't say no to a stack of cheap, used, multi-TB drives.

rsync · 8 days ago

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 …

Strange to see this at 246 points on the front page and no mention of bioglass such as novamin?

Is this mechanism different?

They are their drives. They are reset and re-sold as new.

rsync · 8 days ago

The supply chain - especially for SSDs - is full of old parts being sold as new:

... 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 ...

at some point someone is going to discover the history that the hacker subculture was intelligence influenced all the way down. it has never not been within a degree of separation at every angle from the IC.

it's fine, hackers were probably one of the few constructive successes to come out of it ever. Personally, I suspect the hacker project was on the scale of what the US did during the cold war with abstract expressionist art[1] and literary magazines[2].

As a funnel for getting great, principled talent into the IC, we should be happy and grateful there were people to balance what was coming out of the colleges.

Just because the classified world values hacker skills doesn't mean people shouldn't. I'd say the opposite. There is absolutely a secret world that is accessible on a need to know basis, and it hides everywhere in plain sight for those with the skills to see it. All you have to do is be the among the very best at what you do, in whatever field you are in, and you will encounter it. Saying the Army undermines the subculture that was defcon misses the point. The message of hacking was, develop elite skills and others will find you. not only has this not changed, it is more true than ever.

Oh stop.

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

Considering a URL shortener is basically a KV data store, why? It's an insanely low amount of code to maintain a URL shortener.

rsync · 12 days ago

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.

EagnaIonat · 15 days ago

Totally agree. The API is not shut down yet though.

But one annoyance is to use the GPT-5 API you have to fork over your ID/Passport and a picture of yourself.

rsync · 15 days ago

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 commented on How to sell if your user is not the buyer writings.founderlabs.io/p... · Posted by u/mooreds

doesnotexist · 17 days ago

Situations like this are instances of the https://en.wikipedia.org/wiki/Principal%E2%80%93agent_proble...

In this case, corporate management holding the purse strings but their workers (devs) using the actual tools. The solution they offer to founders is to make the user your champion and have them sell your product for you.

"The meta point here is that you're not going to talk to the credit card holder; the user/dev is going to do that for you.

Give them the best possible chance at convincing the leadership. Make them look awesome for even bothering the leadership with a choice like this. Make it obviously awesome for them to decide “yes”. These users/devs are your sales people."

Maybe that works for dev tools with freemium models, but in many industries where this problem arises its just not possible to even get your product in front of the users. Take hospital systems and EHR purchasing where Doctors and Nurses are the users of the EHR day in and day out but it is the hospital administration that ultimately gets to decide which EHR is deployed. How do you get users to be champions of your product if you can't even get it in front of them?

We made a "CEO Page" for this purpose:

> The author Daniel Lieberman has put it well: Exercise is healthy and rewarding even though it’s something we never evolved to do.

We have ostensibly spent much of our evolutionary budget on the ability to run ~indefinitely no matter what. Compared to virtually any other animal, we can vastly outperform them in the most arduous environments. Our bodies are mechanically optimized for running at every level. We have connective tissue that stores and releases energy. Our bodies can reject on the order of 1kW+ of heat steady-state through the magic of evaporative cooling.

"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.
