I am inclined to try either FreeBSD or OpenBSD.

FreeBSD comes with the bonus that it is supported on some cloud and VPS offerings, so whatever I learn can come useful for practical purpose.

But OpenBSD also seems like a great idea because I have read great things about its security and documentation.

I am not inclined to try NetBSD because it seems to offer neither of these advantages.

Is my assessment right so far or very misguided?

Is there anyone who has used at least two of these three BSDs? What do they recommend?

90 hours/week = 18 hours/day (assuming 5-day work week). That leaves only 6 hours for other chores, travel and sleep. This is not sustainable.

So I'll assume people who can pull off a 90-hour work week work all 7 days of the week which would amount to 13 hours/day. That still leaves sufficient time for a 7-hour sleep and 4 hours of chores and entertainment.

Now, if you are your own boss where you decide the scope and the deadlines, the work is going to be fun and I can understand that you would not mind working 13 hours/day. But I don't think working 13 hours/day for a boss or a company that considers me a cost in a business transaction of buying my skills is going to be fun.

What is p and t? You say that this work shows that p and t are different. What two entities are proven to be equal then in this work?

So does this article prove that two uncountable infinities are equal? Can you tell us precisely what two entities have been proven equal in this article?

I understand aleph-0, aleph-1 and 2^aleph-0 and I also understand that if continuum hypothesis is true, then aleph-1 = 2^aleph-0. Is this what these mathematicians have proven, or have they proven something else?

Can you simplify for us what exactly have the mathematicians in this article proven?

I get that they have proven some infinity A = some infinity B but can you tell us what these A and B are.

Also, isn't the cardinality of reals equinumerous with that of the cardinality of the power set of naturals?

> In a breakthrough that disproves decades of conventional wisdom, two mathematicians have shown that two different variants of infinity are actually the same size

I thought there are only two types of infinity and Cantor already proved that they are different.

* Uncountable infinity which is the cardinality of the set of real numbers

* Countable infinity which is the cardinality of the set of integers

Cantor has already proved that uncountable infinity is larger than countable infinity.

Is this article claiming that mathematicians have proved that these two infinities are equal now? Doesn't that contradict Cantor's proof? What's going on here? Is the Cantor's proof flawed or have we introduced a contradiction to mathematics?

There is no need to imagine. Emacs, Vim, Atom, Notepad++, etc. are all free software.

> ... removal of most GNU tools ...

It is not that GNU tools were removed. It is more like GNU tools were not added. There is no reason too. Mac provides its own POSIX compliant tools. If you prefer GNU tools, well there is GNU/Linux. If you don't mind more traditional POSIX compliant tools, then macOS is a good option, as are FreeBSD, OpenBSD, etc.

It is not uncommon to come across open positions that actually do require Unix (not Linux) experience.

For example, American Express has a large deployment of AIX systems and they indeed look for candidates with experience in AIX systems, although I believe someone with experience in another Unix or Unix-like system should also be okay.

But I agree that such openings are usually quite specific about which Unix system they are working with.

Thank you for commenting here!

I am curious. Can you be a little specific and tell us what Linux or Unix experience do you have?

I mean can you specify the Linux distro names and the Unix brand names (AIX, Solaris, etc.) that you have worked with?

Don't you think the risk you are talking about in believing a 20 year old is exaggerated? Is it that hard to go back to the manager and ask if "Unix-like" is acceptable although the job description says "Unix"? Or just do a little bit of Googling to figure out if what the candidate is saying could have merit?

From my perspective, it appears that the recruiter is the jerk and not the candidate. I have met many computer-illiterate recruiters but never one like this who would repeat the same response over and over again despite the candidate having clarified his position.
