<p>There is a Bambu p1s on its way to me. I will exclusively print ASA and my impression was that the p1s has a good track record with ASA.
My prints will be mounted in glider cockpits and require the UV resistance.<p>Money is a bit tight, so I decided against prusa as my first printer.<p>I am curious if anyone has good experiences with alternatives for the p1s with regards to ASA printing?</p>

<p>Since we can't really formally prove most code, I think property based testing such as with hypothesis[1] would make sense.

<p>> All of the things you mentioned are designed and tested incrementally.<p>In a different way that what is proposed in this thread.
We don't build a small bridge and grow it. We build small bridges, develop a theory for building bridges and use that to design the big bridge.<p>I don't know of any theory of computing that would help us design a "big" program at once.</p>

<p>Not saying you're wrong, but I wonder what is the differentiating factor for software? We can build huge things like airliners, massive bridges and buildings without starting small.<p>Incremental makes less sense to me when you want to go to mars. Would you propose to write the software for such a mission in an incremental fashion too?<p>Yet for software systems it is sometimes proposed as the best way.</p>

<p>Gliders utilize Laminar profiles, while airliners use turbulent profiles.<p>The Laminar profiles perform better, but only when uncontaminated (no bugs or rain). Contaminated turbulent profiles perform better than contaminated Laminar profiles. 
Since regulations state that you should carry fuel for the worst case scenario, it does not yet make sense to design airliners with Laminar profiles.<p>Naturally, manufacturers are looking for ways around this.</p>

<p>Weight affects speed with minimum sink. That affects the diameter of the circle you fly. Since thermals have more lift towards the center (assuming perfectly circular thermals), you are not able to circle in the strongest lift. So you climb more slowly.<p>You can glide faster with the same L/D, so that might be worth it if you try to optimize for speed.</p>

<p>The same angle, but at different speeds. The speed is multiplied by the square root of the weight ratio (new/reference).<p>The minimum speed, at which the critical aoa is reached, increases. And therefore the take off and landing speeds.</p>

<p>Glide ratio and weight are not related. Weight shifts the glide Polar to higher speeds and theoretically improves it slightly due to Reynolds effects.</p>

<p>In agile circles I have seen this exercise:<p>Have two people sit next to each other, each with a blank piece of paper and a pen.<p>Have them both simultaneously write down the numbers from 1 to 1: one time in decimal, one time in roman numbers and one time as letters of the alphabet (a=1, b=2...)<p>One person goes about it system by system (first decimal, then Roman... ). The other goes about it number by number (1,I,A,2,II,B...)<p>Time them both and compare their times.</p>

<p>My understanding of Taoism is that it's all about moderation, balance.<p>There is probably a lot of long-term value in your process. Given my understanding, I would expect you to look at your employer holistically too, and realize that short term results are also valuable in their own way.<p>Like with yin-yang, short-term results hold within them the long term results: the money earnt enables the company to exist in the long term. Lessons learnt from delivering value can spark insight for architecture in the future.<p>Vice versa, the long term enables the short term. A codebase with little technical debt allows you to quickly implement changes in the short term.</p>

<p>>  The system dispensed with a passive common bus and replaced it with an active switching hub to which hosts were attached.<p>I get the impression that the standard still allows hubs to exist, but that you just don't see them in practice.<p>I would be interested if anyone has ever used a 100mbit hub.</p>
