W którym sensie publiczne? (Nie widzę sensu w którym one nie są, a np. autobusy MPK w Krakowie są.)

@ck @delroth

Then it would make sense to ask the person to do something equivalent to attaching the PDF, no?

You might wish to know that the Steerswoman series (if you squint, fantasy; if you squint a few chapter in in a different way, fpvrapr svpgvba) is very much not about preserving status quo.

(But be warned that it's an unfinished series, though there's IMO a good chance of it being eventually finished.)

@_thegeoff Uh, isn't the cap drawn backward?

@_thegeoff

Ah, right, if the input voltage is below the junction drop voltage of the transistor the sourced current doesn't matter at all.

(I once wanted to detect mains voltage via an optocoupler and blown it in, I think, all possible ways due to transients while arriving at something workable that wouldn't continuously dissipate a few watts into a resistor.)

@_thegeoff

Ah, so it assumes that the input signal can only source quite limited current (otherwise I'd expect the transistor to potentially get blown by high current during turn-on transient: there's nothing in-circuit that limits the inrush current through input, capacitor, and transistor).

@_thegeoff Is the capacitor in series with the input or somewhere else?

Unless the transistor is a FET, I don't see how that can work with a single resistor (I expect a resistor in series with transistor's base is needed, as well as a resistor that will allow the capacitor to both discharge and charge).

@b0rk

gpm provided that functionality on text terminals (using mouse to select and to command pasting): https://linux.die.net/man/8/gpm

@munin Isn't this a similar case to 401k plan providers, who (I think, I haven't been in the US for >5yrs) don't advertise much, because in both cases they are usually selected by company owners?

@enablelanguages I think that people would not consider e.g. the current German flag and Nazi German flag to be different versions of the same flag.

@_thegeoff I'm really curious how uniform will the thickness of the glass be. (I know glass bottles are made that way, but I always assumed that works by careful preforming of the hunk of molten glass that's blown up in the form.)

@_thegeoff Ah, and it's obviously convex (because otherwise how would you extract the final product).

@_thegeoff How are you going to remove the print from within afterwards? Also am curious why would you want the mould to be out of concrete -- it's neither flexible (like silicone) or easy to form (like casting sand).

@grimalkina

Ah, so you're thinking of it as a warning sign, in that unexplained drops (or maybe unexpected changes) suggest an undiscovered side effect of an intervention?

@grimalkina Why would we want to increase employee engagement? I don't doubt that it's correlated with things we[1] actually want, but ISTM that it's a poor proxy for them.

@mjg59

I wonder if adding a flag to openat which prohibits dotdot in the path argument itself would be helpful. It's probably way harder to plumb and obviously provides no way to deal with preexisting code, but provides a way to be careful that's much cheaper in terms of amount of coding/thinking/additional dependencies than what's available now.

@mjg59 I think it would be a bad idea in long term.

It's pretty common to join together pieces of paths from different sources. This case and the symlink case are more-or-less-legitimate situations when a program that would wish to set that prctl might need to deal with dotdot.

Given that we're talking about per-process setting, libraries would need to be able to deal with living in a process that has the prctl enabled. Many libraries don't have knowledge about provenance of paths they manipulate, so the most expedient way of ensuring they work is to do dotdot resolution themselves.

This makes bugs where dotdot resolution can be controlled by the user harder to detect, as the path is not passed to a syscall. It also causes libraries to wish to perform symlink resolution "manually", which works around protected_symlinks sysctl.

@_thegeoff

Yeah, you can see how many assumptions one must make to have students model convection: https://ipho.olimpicos.net/pdf/IPhO_2008_Q3.pdf (for example, the convection cell size is clearly mostly a property of the fluid, and yet I've never found any intuitive explanation for what the size should be or even any Reynolds-number-like symmetries).

Hmm... somewhat relatedly: can one get a conservation law from the symmetry that gives the Reynolds number (via Noether theorem on presumably some weird space that includes fluid properties)?

@_thegeoff

But they would impart only angular momentum to the pot, and not momentum (because they leave the surface level roughly constant and unchanged if averaged over horizontal circles a cm or two in radius). So, this explanation could be tested by letting the pot slide ~frictionlessly sideways and seeing whether its center of mass moves sideways, right?

@_thegeoff

Ah, and I think the rocking would start before major bubble-implosion-noise and clearly visible bubbles (and I messed up the explanation I was thinking of at that time -- the density changes would come from thermal expansion as opposed to steam creation).
