The "free" version of Vivado is used to develop for Xilinx/AMD's lower tier FPGAs. While offering what I assume are lower profit margins, these lower tier FPGAs make up a large portion of Xilinx/AMD's chip volume.

Xilinx/AMD charging for any of their tools is also a recent thing. 20 years ago, you could download these tools freely without even having to register on their website.

My minivan has more 50% weight capacity than a Toyota Tacoma. I can haul more construction debris and load/unload them easier because my tailgate is lower. I wouldn't want to try to haul mulch or manure though. That being said, most of my friends with trucks have caps on the back and can't haul mulch any easier than me.

Loading drywall into my minivan is a lot easier than a truck. I can fit whole sheets and close the back gate so I don't need to strap them down and they are protected from the elements.

mm/hr is more useful for areas that get lots of rain. When I was living in Seattle, chance of rain was meaningless but mm/hr made the difference between being able to do an outside activity or not. In California, chance of rain makes sense because it rains very little.

Jobs was actually a technician at Atari, assembling circuit boards during the night shift. Jobs was later paid by Atari to make Breakout, but basically subcontracted it to Wozniak for 50% of the contract. Jobs ended up paying Wozniak less than 1/10 of how much Atari paid him.

I think this can just be summarized to "write any HDL like you are modeling real hardware." Both VHDL and Systemverilog were primarily intended for validation and synthesis is a second class citizen.

You can pretty much do everything in Vivado from the command line as long as you know Tcl...

Also, modern Verilog (AKA Systemverilog) fixes a bunch of the issues you might have had. There isn't much advantage to VHDL these days unless perhaps you are in Europe or work in certain US defense companies.

I live near both wind turbines and oil/gas fracking sites in Colorado. The wind turbines are far less obtrusive. Fracking sites produce a lot of noise and they try to hide them with these giant walls that look like a post-apocalyptic fort. On top of that, because they don't disclose their fracking fluids you always kind of have ground water contamination near your home on the back of your mind.

I'm not even against fracking but the alternatives to wind and solar are more a public nuisance to live around.

TouchID doesn't really for me on my Macbook or iPad. It has about a 25% success rate. I think one issue is that I work with my hands a lot.

It is not cool or sexy, but a surface tablet makes a great travel device because it is a full computer that is also a tablet. You can also use it during takeoff and landing when laptops are not allowed.

The purpose of de minimus is to streamline small shipments, commercial or not. It can't really be abused unless the declared value is false and it is really over $800.

If you are taking issue with Temu-like shipments, that is more of a postal treaty issue.
