Surprising behavior in GNU tar
Here's a fun game for you: what do you expect to be the state of the filesystem after running the following commands
in an empty directory on a Linux system?
$ touch foo:bar
$ tar -cpf foo:bar.tar foo:bar
$ rm foo:bar
$ tar -xpf foo:bar.tar
Do you expect the directory to contain the files
What if I told you that instead the directory would only contain
foo:bar.tar and stderr would say
tar (child): Cannot connect to foo: resolve failed
Yep! It turns out that GNU tar, if passed a …
I miss working from the office
I went into my office yesterday for the first time in a few months to pick some stuff up. We got notified
a couple of days ago to get any personal property out of the office before Thanksgiving or else it'd be
thrown out, so I guess we're moving out of the office. It was a pretty eerie place to be; even now, 8
months later, most people haven't been back and it kind of looks like the entire office was abducted by aliens in
Despite how weird it is, I still miss working out of the office.
Summertime California Sky
It's 9:45am on a cloudless Wednesday morning here in summertime California.
My light meter reads 14 lux pointed directly at the sky — about as much as the
middle of the night (with local light pollution), or about 1/1000 as much as a normal morning. They tell me that the skies are this apocalyptic shade of red due to the smoke from the 16 major wildfires currently burning in California. Local news has plenty to say on the cause if you want to read up. Damn if it isn't disconcerting to live through, though.
What world did I …
Hello hypothetical readers; sorry for my absence, but I've spent the last weeks pretty well busy – as I foreshadowed
in May, I have a son now!
It's been quite an adjustment. Isaac was born on August 7, 2020 after a very long labor, but he's happy and
healthy now. I got 3 weeks off of work, which I spent with my wife doing intensive child care. Let me tell you, I have a
whole new respect for single parents. Caring for an infant with just the two of us (since none of our families or
friends can visit or …
UC Botanical Garden
PSA for folks in the Bay Area: The University of California Botanical Garden has re-opened for limited, outdoor-only visits. Seems like a nice (and
reasonably) safe place to go during the pandemic. It's July, so not much is in bloom, but it's still beautiful.
It's like being Slashdotted, but it's not 2002 any more
So, my etcd post was cross-posted to Hacker
Reddit and probably
more places. For the good of my own sanity, I'm not going to try to read through the comment threads on those other
sites; generally, I try to avoid Hacker News anyway. Just some brief, off-the-cuff follow-ups:
- Yes, I recognize that the post from the other day was, uh, inflammatory. I did not write it as a persuasive
thinkpiece targeted at the critical 18-25 demo or whatever. It's just some notes while I was in the process of
rewriting some software from the etcd v2 API …
