I was going to put ethernet surge protectors on both sides. My plan was a PoE switch (Ubiquiti flex) with two cameras and an AP, powered by my main switch which is on a UPS. How much safer is using fiber, and giving up on battery backup? I&

I recently moved into an all-brick house, it's really quite amazing to me just how much it kills 5 GHz wifi. I knew it was a thing that happened, but it was interesting to walk around with a signal tester and observe it first-hand. Eve

There's a good comparison on the Scoop wiki [1]. Chocolatey is a mixed bag. Since it is basically just wrapper scripts around upstream installers, it very much depends on what the upstream installer does. To me, it acts less like a pac

Google started doing leap second smearing [1] in 2008, which basically slows down each second over a 24-hour period, noon to noon UTC. ntpd also supports this [2], though I'm not sure how popular it is in practice. Anyone making use of

Seconded. This is a very compelling read, and a great graphic novel style. One of the things Joe says several times is how part of the design of the elan program is to be so absolutely insane that it literally sounds unbelievable if describ

Does Fossil have a unique or killer feature that makes it a good alternative to git, other than "simpler to use"? I don't like the monoculture either, but at this point some knowledge of git is an essential skill. In fact p

I think my first intro to this was from a Not Just Bikes video on speed limits [1], and that profoundly affected my opinion on this stuff. I now think a lot of road design is just utterly broken, and it includes speed limits, what that chan

Like so many things, this is just all about trade-offs. Self-host is not a silver bullet, it just swaps in a different set of problems. Risk is part of it. Cloud service disappearing, discontinuing, failing, changing pricing, or modifying p

I'd argue there are better API patterns for this though -- keeping in mind this values code readability (and correctness) over micro-optimization: .setPriceInCents(100); .setMassInKilograms(2); .setTimeoutInMilliseconds(3

Totally agree, but then I would expect the code would be: request.setConnectTimeout(getDefaultTimeoutFromEnvironment()) with getDefaultTimeoutFromEnvironment() returning a Duration. Ideally this is consistent throughout the codebas

This doesn't work looking at a PR. It also doesn't make a unit error stick out, as you have to take the time to specifically hover to check. What I mean by this is consider you've opened a mature code base and are browsing ar

There's a performance penalty which happens if you don't need async (eg, if the innermost thing is actually using Task.FromResult), and I've never tested but there's probably some cutoff point where if an awaited operati

Most of the problems I've seen of this sort are from easy-to-make design issues, like constantly reassigning a string value to modify it (lots of allocations, with lots of GC), or using an IEnumerable with .count() then iterating with

I agree with what you're saying as far as framing it around "don't say hello": it's really saying "don't just say hello and wait", but that's not as catchy. If you ignore the literal "no h

Yeah, this is a good idea. I'd add a tip: start writing your notes in the speaker notes and leave the slides blank, instead of the other way around (which is kind of what PowerPoint's UI pushes you towards). Only create the actual
