Is "Bowling alone" (by R. Putnam) a good read? in c/books@lemmy.ml

Thanks, that's good to hear. If its well readable, I think I'll order it.

Thanks for your input! I think the current version even received an update about the internet.

The topic of the book sounds interesting, but I'm wondering if it is still a good read today/aged well and if it is suitable for someone who isn't already familiar with sociology much. Is the writing style easily digestible, or is it a "hard read"?

Is there any mailcap tool on OpenBSD? (feddit.de)

I'm looking for a tool, that allows me to open different files with an appropriate tool automatically. I've got xdg-open available on my system, but it seems quite cumbersome to configure. Thus I was looking for an alternative.

The mailcap format seems to be somewhat common and easy to use, but pkg_info -Q mailcap returned no results. Is there any tool that supports mailcap files in the ports, that I missed?

If there is none: Is there a good alternative, that you use?

What is so special about the natural logarithm? What is it good for? in c/nostupidquestions@lemmy.world
[–] dieter_hermann@feddit.de 1 points 1 year ago

Your explanation makes a lot of sense to me! I didn't know that exp'(x) = exp(x), but can see how this could be an interesting property and in turn makes ln interesting.

You saying, that it often doesn't matter which logarithm is used, made me check and realize that log_a(x)/log_a(y) is the same as log_b(x)/log_b(y). Thus I understand that it really doesn't make a difference which logarithm is used when "comparing the magnitude" (not sure if this is the right term) of numbers.

I feel like I have a much better understanding of ln now. I'll assume that the base of an algorithm is often basically a random choice and base e is often used because of its "interesting trivia".

Thanks a lot!

I understand that log2 is useful for informatics, e.g. to determine how many bits I need to represent a given number. I understand that log10 is useful to determine the order of magnitude of numbers.

However, I'm having trouble understanding what makes ln interesting. It seems like it's used a lot, but to me it just looks like a logarithm with a very weird base. What are the uses for this logarithm?
