New comment by tostr in "Is 3D printing being held back by an invalid patent?"

Since you wrote

> [...] is a significant limiting factor for the structural integrity of 3d printed parts

I went and checked. There is a youtube called MyTechFun[0] who does proper material testing, and being a patreon I have access to the entire table of his results. The comparison I made is tensile strength vs layer adhesion, which is the same test (basically pull until it breaks), but the sample is printed lying down or standing up. I expressed layer adhesion as a percentage of tensile strength, and sorted by this.

The best three I will show here (tensile and adhesion are in kg):

  Name, Tensile, Adhesion, Percentage
  YXPolyer Nylon[1], 63.1, 66.4, 105
  PolyMaker PLA Pro[2], 56.55, 50.6, 89
  PolyMaker CoPA[3], 66.3, 56.6, 85

While the tensile strength is higher for all (except one), it does not seem to be quite as limiting a factor as your claim makes it out to be. We can find percentages of >70% for all major filament types. But to be fair, most of them seem to cluster around 40-50%. While this is not great, given the choice of materials I think it can be worked around quite easily.

It saddens me to hear that, Paul made a lot of very interesting content if you are interested in guns, ammo and everything around it. It was also very much devoid of any politics or religion, which I deeply appreciated. This video is very much in character for him, it was so enjoyable to watch yet also filled me with more sadness than I would have expected.

His style is not for everyone, but if the topics he covers are of interest to you I very much suggest giving his channel a try, I know I learned many things from him & the team.

I just wanted to post that I can't find anything about it being forbidden, but there is actually a link in the post[1]. So basically the situation is:

Mit einer Funkanlage dürfen nur solche Nachrichten abgehört oder in vergleichbarer Weise zur Kenntnis genommen werden, die für den Betreiber der Funkanlage, für Funkamateure im Sinne des § 2 Nummer 1 des Amateurfunkgesetzes, für die Allgemeinheit oder für einen unbestimmten Personenkreis bestimmt sind.

Which in English would read something like this:

With radio equipment you are only allowed to listen to, or take note of in some other way, those messages that are addressed to the operator of the equipment, those messages that are addressed to ham radio operators in general, those messages that are addressed to the general public or for an undefined group of people.

This is of course absolutely unenforceable, untraceable and generally ridicoulus, but it is what it is. Imagine your neighbours having very loud arguments (or very loud 'horizontal discussions') in a clairaudient flat, and then telling you that you cannot listen to it. And being correct legally ;)

New comment by tostr in "Mounting your iPhone on your motorcycle can damage its camera (2022)"

tostr — Wed, 23 Aug 2023 09:26:12 +0000

Have you just mounted them, or mounted them and used the camera while riding the bike? The iPhone has sensor-shift image stabilization (what camera manufacturers are calling IBIS - In Body Image Stabilization) and if this is engaged (for example while filming) it would be much more prone to damage than if you are using the phone for, say, directions only with the system parked in transport mode.

At least this would be my assumption, I don't know where this problem comes from exactly.

New comment by tostr in "DIY Espresso (2020)"

tostr — Thu, 17 Aug 2023 12:25:26 +0000

That is a massive oversimplification. There are a huge number of variables that have a very noticeable impact on the coffee. Pressure (over time), temperature (over time), flow rate, composition of the water, puck resistance (and change over time), many ways to change how the water extracts from the puck, pre-infusion time (and temp. and pressure...). This is just the machine side, ignoring beans, grinding, distribution and tamping.

And the effect of a single one of those variables can be the difference between a god shot and something that tastes rather off. I am not saying you need a machine that allows you to control all of this to get good shots, but the effect on the result is still there. Something like a Decent DE1 can actually control a lot of this, a lever machine actually allows a lot of control as well. 100$ pump machine to an expensive espresso machine is a huge difference in many regards. Consistency being probably the biggest one.

So no, I do not thing your assessment on complexity of espresso making is an accurate representation. I concede however, that if you know what you are doing, good espresso can be had on cheap-ish machines, it's just much harder and less consistent.

New comment by tostr in "Debris found came from missing Titan sub, says friend of passengers"

tostr — Thu, 22 Jun 2023 22:40:10 +0000

From the page you linked:

>Why Isn't Titan Classed?

[...]

>Classing assures ship owners, insurers, and regulators that vessels are designed, constructed and inspected to accepted standards. Classing may be effective at filtering out unsatisfactory designers and builders, but the established standards do little to weed out subpar vessel operators – because classing agencies only focus on validating the physical vessel.

[...]

> The vast majority of marine (and aviation) accidents are a result of operator error, not mechanical failure.

Did they not consider that the reason for this fact is, oh I don't know, maybe because the vessels have passed the checks for mechanical integrity?

You can't make this stuff up...

actually, since there is a short delay between article loading and the nag screen, you can even click "reader mode" just after (re-)loading the page and get it to work

not as elegant as your solution, sure, but it works in a pinch (also probably easier to do on mobile)

Would you mind expanding a bit on your experiences with running linux on mac hardware? Especially the M1, what is your daily experience like? Any pain points or gotchas?

Reason for my question is that I used to run linux on the mac as well (10 years ago), and I love the hardware. I don't think there is anything that even comes close hardware-wise. But currently I am on mac os, well, because it works basically ;) But I would be curious to know if switching over again would make sense now, without too much hassle.

Are you saying 17deg from horizontal? Let's ignore wind and other influences. A normal plane can not climb more steeply than 17deg?

I'm not implying you're wrong, just very surprised to see this low a number. I would have guessed much closer to something like 45deg, maybe even more.

New comment by tostr in "Firefox 61.0 Released"

tostr — Tue, 26 Jun 2018 18:14:20 +0000

I only use firefox (for privacy reasons). But the macbook-burning-a-hole-in-my-pants behaviour that firefox creates on these sites has led me to using mpv with youtube-dl to watch most of youtube and all of twitch. If you have both installed you can just do a 'mpv https://www.twitch.tv/username' and it will work quite nicely. You might need to set up mpv to get the best quality, I think putting 'ytdl-format=bestvideo+bestaudio/best' in ~/.config/mpv/mpv.conf is sufficient. HTH.

I'd wager that my iPhone and MacBook (encrypted) are safer against 99% of all adversaries on this planet. Now maybe the NSA and some other high-level players can get around even the newest security features, but I'm pretty sure the crook that steals my phone can't, as well as my local police. What else should I be afraid off? If the NSA want to screw me, they will find ways around my computers. Same for CIA/FBI etc.

To me it appears that a modern iPhone is the most secure phone you can own. Not claiming to like it, but it is better than the one alternative OS you could use.

And other than the big players? Linux on your phone - probably a PITA; Linux on your Laptop/Workstation - fine if you don't need specific programs. But want to develop for iOS? It's mac all the way.
