Same! I remember a co-worker getting a call from a relative about it so I went to cnn.com. ...only to see it time out. Same with usatoday.com and abcnews.com. At that point I knew …

> stdout and stderr output often ends up in a black hole Ain't that the truth. Literally every crontab I've written for the last 10 years has had this in it: 2>&1 | logger -t cron-…

Beat me to it! I did in fact have experiences like that with Perl in years past.

Your username is nice nostalgia for me. :-)

This is one reason why whenever I build a new project, I build it inside of a Docker container. That way, the project has just the dependencies it needs, and I know I can rebuild i…

Check your Python version. Try switching to the newest version of Python with something like Pyenv, or even try spinning up a Docker image with something like: docker run -it -v $(…

Using CAs and signed certificates in SSH is definitely the way. If anyone wants to play around with that, without the risk of locking themselves out of a server, I built a little "…

I wrote my first ever TamperMonkey script, to add some tools to a Facebook group that I moderate: https://github.com/dmuth/facebook-javascript-toolbox

Author here! I built this website because while PECO does have a very nice outage map ( https://secure.peco.com/FaceBook/Pages/outagemap.aspx ), I found that when I lost power and …

Definitely. This is one of my favorite books due to both the writing style and the "behind the scenes" aspect of living and working in Antarctica.

Author here. I’ve been using Httpbin for years and have grown to love the site. However, I noticed that the project seems to have fallen into disrepair--the GitHub repo hasn’t been…

If you want to test to see if you're successfully sending out IPv6 traffic, I have an endpoint for that: https://httpbin.dmuth.org/ip/v6

I can offer what much younger me was once told by a senior engineer: 1) With respect to not having whitespace: "Not everyone is as smart as you, and you need to ask yourself, do yo…

I wrote an open source project that may be useful to people here: https://github.com/dmuth/git-rebase-i-playground It lets you create a Git repo with synthetic commits and has samp…

For those curious about how SSH CAs and key signing works, I wrote a blog post about that awhile ago: https://dmuth.medium.com/ssh-at-scale-cas-and-principals-b27... I also created…

That's interesting about the blocksize. I was never impacted by that because I mostly use dd for writing large files, and a large block size always made more sense to me. For examp…

Agreed--SSH certificate authorities (and principals) are powerful things that can be used to manage SSH access at scale. My workplace is a large enterprise that uses our own CA for…

I built something which may be able to help: https://github.com/dmuth/grafana-playground You'll want to spin this up in Docker Compose, and to add custom hosts upstream of you (suc…

We had something like this in a Philadephia sports stadium as well: https://www.inquirer.com/news/the-secret-apartment-vet-stadi...

If you use LetsEncrypt and Docker, I can recommend HTTPS Portal to automatically manage your SSL certs: https://github.com/SteveLTN/https-portal I use it for my blog and have never…

"Never ever copy your private keys on a computer somebody else owns." FTFY. In more detail: if your private keys ever leave your computer via the network, it's a good idea to consi…

> I got in a painfully stupid argument with a middle-age IT admin “we don’t want to our employees installing apps” If they think that any domain that ends in .app is for installing…

Very cool. I see my page ( https://hnbadges.netlify.app/?user=dmuth ) has the "colorful" flag, probably due to the profanity I have in my bio. :-)

I don't disagree with your post, but one thing I want to mention is the origin of the term "Incident Commander"--it doesn't exist to be cool, but rather derives from how FEMA handl…

Oh god yes! When I'm interviewing someone, especially for a senior position, I want to make sure that they know what they say they know on their resume. Having code up on GitHub, o…
