It's always a method. Ruby doesn't expose instance variables unless you define accessor methods for them.

I use the TP-Link TL-WR902AC for this, it's cheap and has a MAC cloning feature that makes it pretty easy. Unfortunately the firmware isn't updated anymore and it's missing a VPN client, but apart from that it gets the job done.

Many delivery services are operating, or they could have a caregiver pick it up for them.

DoorDash is the worst. They inexplicably banned me from their platform after giving me a credit for a bad order. I filed several support tickets over several months and kept getting canned responses about how they were "looking into the issue." Eventually I just switched to Uber Eats.

I was an expecting an article about waterproofing differences between windows that open to the left and those that open to the right. Forgot this was HN.

The Hit AnyThing bot is pretty cool too. You can hear them both on "Computer Controlled Acoustic Instruments pt2 EP" (2015).

I love awk. I used to be afraid of it, but I started using it just to pluck columns, and over a couple years actually started to grok it.
Also, I learned today that cat takes a -n option to prepend line numbers to the output! My solution ended up being
cat -n faces.txt | sort -k2 -k1n | uniq -f1 | sort -nk1,1 | cut -f2-jenrzzz | 11 years ago | on: Huawei Watch
More convenient for the right index finger.

I didn't say it couldn't be questioned. I was just explaining some possible reasons why the patch was so esoteric, and pointing out that things that seem straightforward to MRI hackers often aren't to people who don't dig through Ruby internals every day.

It's an optimization hack. By nature, they aren't that nice to look at.
`sym_equal` only makes 2 appearances in the whole codebase (to be bound to `Symbol#==` and `Symbol#===` in string.c), so there's not a whole lot of room for confusion.
Also, this is Ruby core! Smart people do what works and makes sense to them and don't spend a lot of time worrying about how clear it is to us unwashed masses.

Actually, he wrote it!
jenrzzz | 11 years ago | on: Ask HN: Is it just me or why does Docker suck so much?
It may just be you, but given Docker's youth and novelty, you should expect some frustration. If everything about it seems like a pain in the ass, it might be the wrong tool for your use case.

That's why you need to find a bricklayer with a O(1) bricklaying technique.

You can use symbolic modes in chmod too if you can't remember the octal representation. For example, you could set 0755 with "u=rwx,go=rx."
