I also discovered this. I was panicking a little bit when I started smelling what seemed like sewage in my basement. In a 100 year old house, I was wondering what broke. After a few hours, I figured out that there were potatoes rotting in the pantry, which was more open to the basement than it was to the main floor of the house - so all the smell sank down there. It was honestly a relief.

The further you go, the more specialized it gets. There are people I know doing their PhDs in CS, but it was pretty much just straight math. I'm now an expert in a very specific area of robotics. But it's only worth it if you have a specific reason to go to grad school, like for a particular career path. If it's just because you like learning, it's not worth it. There's a big opportunity cost.

My older sibling did something similar - getting Ubuntu installed on my very first laptop (a 9" netbook) back in 2008 and replacing windows XP. But be warned: it is a slippery slope. At the time , I just wanted a computer that I could take class notes on (high school), and never wanted to touch programming or the terminal. Now I have a PhD in computer science. I still don't use Arch though.

And for me, as one of the few women in my CS program: plenty of opportunities, and plenty of douchebags.

These ads are getting so much more prevalent, and so much more subtly marked. Google (and places like reddit and Facebook) designs them to feel as much like organic content as possible. I have a pihole on my home network, in part to prevent exactly the type of mistake you described.

It's two-fold: lots of parking, and lack of good alternatives. If we just reduce parking requirements, but don't provide safe, reliable alternatives (eg quality public transit and bike lanes), you get angry drivers and sad (or dead) cyclists.

Oh boy, I keep a page just for this!.

I need to update it (for example, Arachne perimeters in PrusaSlicer now let you print extra thin perimeters), but it's useful to have a reference for common tolerances/dimensions like screw holes.

But a couple of my little additional pet peeves:

  • Don't put fillets on the underside of prints (against the bed). The nearly-flat angle always droops and looks bad. Use a chamfer instead, or make a fillet that actually starts at 30° from horizontal.
  • The weakest direction is between layers. Design your part such that you can print it in an orientation where the thin/weak parts aren't printed where the layer lines can snap (eg, print it flat vs vertical)
  • Just like the straight lines inside screw head holes, thinking ahead in your design can prevent/minimize the need for support material. The earlier you start thinking about this in you design, the easier it will be. For example, can a part be designed with a 30° slope on an underside instead of being flat? Can you think about your print orientation early in the design process to avoid overhangs?
  • Chamfer of fillet inside corners, if it's a structural part. This will greatly reduce stress concentrations.

Personally, I don't use 3 perimeters on most of my prints. On my prusa, they look totally fine with 2 perimeters. I only switch to 3 if I need the strength (which also almost always means I'm printing in PETG, rather than PLA, FWIW).

My city bans: converting single family home into two owner occupied units, as the city gets denser.

My city allows: international developer gutting a single family home into a 7 bed, 7 bath house to rent by the room at egregious rates by a corporate landlord, because it's still technically single family because there's only one kitchen.

These zoning laws are actively discouraging urban development that supports the residents.

It is possible to get transition care while on Medicaid in some states, at least. Because it's healthcare! So that would qualify at "taxpayer funded." I know some states explicitly ban it, and not sure what Medicare covers. There are also government employees who can get transition care through their insurance, so could be considered taxpayer funded?

In any case, I'd much rather have all trans people be able to get taxpayer funded transition related care.

Ha, realizing the oddity of my phrasing in hindsight. My guess was OP had some smidge of a memory hearing that insulating over wire was bad, so thought it would be worth a little context.

(In tithe US) It's not safe or up to code to cover knob and tube wiring with insulation because that can cause it to overheat and start fires. But this is modern Romex wiring, not 100+ year old wiring. Many wires in your house are running through insulation - like everything in an exterior wall. They're designed for this.
