tdudhhuon The xz sshd backdoor rabbithole goes quite a bit deeper

Sometimes I think it could be someone who was forced to embed the backdoor but was smart enough to make it detectable by others without raising suspicion by the entity that was forcing him.

tdudhhuon What makes housing so expensive?

Isn't the main problem that all the jobs are located at central spots? There is a huge amount of land where people can live. But building a cheap house at a location where you can't find a job leads to nothing.

There is also a kind of hype of homesteading. But you should not underestimate the huge amount of work it takes to keep yourself alive. So for most that is not an option.

tdudhhuon Smoking cannabis is now legal in Germany

Hidden alcoholism is a huge problem.

There are estimates that 70% of alcohol addiction is hidden.

tdudhhuon Smoking cannabis is now legal in Germany

While I think freedom is good, I also think there are more people destroying their lives with drugs than people who can regulate their use.

I've seen so many people waste their life on weed and alcohol that I can't be very happy about this news.

tdudhhuon Ethereum has blobs. Where do we go from here?

Yes, they can prove ownership of an art peace but can not prove the art peace even exists.

tdudhhuon Ethereum has blobs. Where do we go from here?

https://internetcomputer.org/

A YT video about this: https://youtu.be/wk3FxuA5DKs

I am still very sceptical about this because it looks very slow, but it seems to work.

tdudhhuon Sam Bankman-Fried sentenced to 25 years in prison

I think this is a wise answer. Thank you.

tdudhhuon Ethereum has blobs. Where do we go from here?

Some days ago ICP showed it can run ML on a blockchain.

While this is nice and does show that distributed computing is a real possibility I also don't think that anyone is going to switch from Amazon/Azure to ICP any time soon.

But I must say the idea is really nice. It's very easy to develop Actor model based software and deploy it on ICP.

tdudhhuon Sam Bankman-Fried sentenced to 25 years in prison

The difference between opinions in this thread is interesting.

I think it's mainly because some see a punishment as revenge and others as correction.

But, as user publius_0xf3 is showing, revenge does not work. The victims don't get their money back.

If this sentence is used as correction I also think it does not work. Would such a correction really take 25 years? His life is over. I don't see how such a long time is helpful to him, to his victims and to society.

tdudhhuon Schiphol conducts trial with self-driving buses on airside

Self driving is a bit of a stretch here. There are already a lot locations around the world where autonomous vehicles are driving, even in the Nederlands.

For example in the Netherlands there is a container terminal that has been using autonomous trucks for decades. And since 1999 there have been autonomous busses in Rotterdam.

Yes they are self driving, but not as smart as self driving means today.

tdudhhuon My Apple Vision Pro Nightmare

"The earliest computers were open sandboxes of creativity ... But later generations of devices, especially smartphones and tablets, are increasingly walled gardens"

Exactly what Alan Kay has been saying for years.

tdudhhuon Recent 'MFA Bombing' Attacks Targeting Apple Users

Why? You can rate limit the business logic but still show the user the default flow.

For example: if a user is requesting a reset password link 10 times a minute you can just send the link one time but display everytime that a reset link was sent by email.

tdudhhuon Inkjets are for more than just printing

I expected a much higher price. While $190000 is steep it doesn't seem that much for such printer. For example: Nexa3D ships SLS printers for over $500000

tdudhhuon Friends don't let friends export to CSV

"Of course there are better formats, but all these sources aren’t able to agree on some successful format."

It's the same with csv. They come in all kinds of formats because nobody agreed on the standard. Comma separated, semicolon separated, pipe separated, escaped, not escaped.

Everytime I have to deal with csv I first have to figure out how to parse it in code.

So I think the author is right, we must agree on a better format because that is what friends do.

You are also right because it's an illusion to think that this is going to change anythime soon. But who knows..

tdudhhuon Swedish composer becomes Spotify's most-famous musician you've never heard of

I wonder if this is the same for all those fireplace and aquarium movies on streaming services.

tdudhhuon High-speed microscale 3D printing

"which I never read about on Tom's or Ars"

Aren't those consumer websites?

The 3D printing industry is over 50 years old. And I believe metal printing has the biggest market. But those printers are super expensive. Not something an avarage consumer is going to buy.

By the way: I don't think you can buy a Carbon printer. You need a service contract so you can lease them.

tdudhhuon High-speed microscale 3D printing

Maybe for some types of osmosis?

Creating tiny holes for osmosis is of course already possible but with 3D structures it might be possible to create things like ventury effects.

tdudhhuon High-speed microscale 3D printing

This almost sounds like what Carbon [1] is doing with their 'normal' resin printers. They project images through the bottom of a vat filled with resin. But a special membrane creates a small 'dead zone' where the resin does not cure. This makes continuous printing possible at an almost infinite z / height resolution. I believe they also use this for chemical properties because the small interface is full of oxygen.

tdudhhuon Glassdoor is now adding real names to user profiles without consent

Pro tip: always use example.com because then you are sure you are not spamming someone's inbox.

tdudhhuon Flightradar24's new GPS jamming map

Is interference the same as jamming?

I am absolutely no expert in this but I can imagine that even natural occurrences can interfere with the GPS.

tdudhhuon Climate Change Speeds Up as Major Indicators Blow Off the Charts, WMO Warns

Disclaimer: I am 100% convinced climate change is real and humans have some influence in it.

My question: do we even know what the baselines are? If we look at the history of the world climate has never been constant. So on one hand I am afraid humans messed up, on the other hand it's very difficult to see if the current climate change is totally caused by humans. Especially now El Niño is causing changes all around the world.

tdudhhuon Long Covid brain fog may be due to damaged blood vessels in the brain

When you look at the Epstein-Barr virus we call the result of the infection all kinds of syndromes.

Personally I had Long Epstein-Barr for almost a year. So I know it's no joke.

Most virus infections can cause long term problems.

tdudhhuon WebSockets vs. Server-Sent-Events vs. Long-Polling vs. WebRTC vs. WebTransport

Not in the article by also relevant is short polling. While this does not send messages from a server to a client it can still be useful when all other options are not available (on shared hosting for example).

In my experience it even works great when the poll interval is long (for example 20 seconds) but when you also include the message list in each response. That way the client will be up to date when it interacts with the server: user presses a button -> the client sends a request to the server -> the server reponds with data and also a list of the latest messages.

tdudhhuon Ask HN: Do you also marvel at the complexity of everyday objects?

Recently I was repairing a BambuLab A1 mini 3D printer.

Man, there is a lot of thought and tech in those things!

So yeah, sometimes I Marvel.

tdudhhuon Losing faith in testing

I am not saying you should not test. To me it seems obvious that you test what you create. But it is impossible to test everything.

When you fail fast you are quicker to notice it yourself. And when it was deployed without you nothing the bug it will still surface very early because it breaks your app.

Broken gets fixed, shitty lasts forever.

tdudhhuon Losing faith in testing

I have more faith in 'fail fast/early'.

It's impossible to test everything. But if you fail fast at least you know something is broken.

tdudhhuon How web bloat impacts users with slow devices

You are right.

I browse the web on Firefox with uBlock Origin, 3rd party cookies disabled, and so on.

So I am missing the bloat most people talk about.

But still apps like Clickup are really slow. It's just bad software.

tdudhhuon How web bloat impacts users with slow devices

Not only the user is affected by this.

The difference between a 2MB and a 150KB CSS file can be a lot of bandwidth.

The difference between a bad and good framework can be a lot of CPU power and RAM.

Companies pay for this. But I guess most have no clue that these costs can be reduced.

And some companies just don't care as long as money is coming in.

tdudhhuon BlenderBIM – add-on for beautiful, detailed, and data-rich OpenBIM with Blender

CAD modeling in Blender is only possible with geometry nodes.

I did some projects using geometry nodes. It is a nice step towards CAD modeling because it is fully parametric.

CAD models are mathematical models and thus infinit accurate. Solid models are not. But sometimes they are good enough. I create a lot of models in Blender for 3D printing.

tdudhhuon Building Meta's GenAI infrastructure

As far as I know training is the main issue.

I don't know a lot about ML. Does anyone know if it is possible to keep training the system while it is running?

That would help a lot if you don't have the possibility to use huge training sets as a starting point.
