It doesn't even have to be that high of level of competition, just highly competitive. I went to high school in the late 80s/early 90s. Cross country runners at multiple schools in our area were openly blood doping with autologous transfusions. Steroids were openly sold in the weight room and football locker room (and we were just a mid-tier football program). Supplements were constantly coming on the market ahead of regulation; even as a high school athlete I took supplements in good faith that later ended up banned.

We had a very small handful of generational athletes are our school during my time there (at the level where some here would certainly recognize their names). Some were clean at the high school level, some were not. Inevitably the ones who used performance enhancers started having injury issues at the college level that became worse in their post-college careers (olympic/pro). I don't know for certain if the clean athletes stayed clean after high school, but I learned from a couple of them later how hard it was to stay competitive against the wide spread use of PEDs in their various sports.

Basically, by using the 2-prong, you run a higher risk of your PC being destroyed by excess current. A surge protector will not help. A three prong adaptor will probably not help (unless the outlet box itself is grounded).

The GFCI will protect you if your PC gets energized by the circuit (e.g. if you have a metal case and the metal case gets energized).

A GFCI won't protect your PC against a power surge though. Your equipment would still get fried. (This is why an ungrounded GFCI carries a "No Equipment Ground" sticker.)

Wall to wall won't hold them, because they expand and contract a significant amount with any temperature change. Before using double sided tape or construction adhesive, I would suggest using low pile carpet tiles under the mats. With this, the mats won't get damaged if they shift, and it is easier to pick them up and clean them or clean under them (like if something gets spilled on them).

Buy a few rolls of mat tape and use those to cover all the seams. You can go with clear, or get colored opaque "striping" mat tape if you want to have some sort of pattern to your edges and completely hide the seams. That will make the tiles shift as one big mat, reduce gaps, resist spills and dirt getting under the mats, and make anchoring the mats more effective.

To really be certain, it would be a good idea to get a multimeter and verify that you are getting the correct voltage when testing between hot and ground (should be the same as testing between hot and neutral). You can do this carefully with the bare wire in the box before cutting it. But be careful, as you would be reaching into the back of the potentially live box with a probe while the circuit is energized!! (Highly recommend safety gloves if you do this.)

If you look for Tatami tiles, that's another type of closed cell EVA foam tile, also commonly called judo mats (normally 7/8" thick) or MMA mats (normally 1" thick). A step up from that would be cross-linked polyethylene foam (XLPE), with a vinyl facing; these are marketed as lightweight home wrestling mats. If you go that route, you will want rollout mats over folding mats for a more permanent installation.

Check out the video section here for some great and overly dramatic explanations:!

(They have some very extensive buyer's guides on this site too.)

Test them out first. There is a lot of variability in quality of these kinds of tiles. They often need to be taped together to prevent gapping, sliding, and spreading. Some tear very easily, others will take impressions easily (and permanently).

Even with quality tiles, there is a good chance they will still slide on the concrete and you might need something underneath to prevent that. When I have seen these used in dojos and gyms, they frequently use carpet tiles.

Be careful of varnished doors though when pulling from donated stock like that, as older door varnish contains lead. (We found this out when we looked into refinishing all the old wood doors in our 1920s house. Turns out it is not something to attempt without really good dust control, even outside.)

>You can go nuts with fiberglass and house wrap, but one little crack letting cold air in will chill a room out very quickly.

Or, conversely, why throwing down a simple draft blocker or tacking up a single piece of rigid insulation in the right spot, or even just putting plastic film over a key window, can make a huge difference in a room.

The problem comparing your quote with american states is the phrase "long been run". Boot is talking on time scales longer than the US has existed.

Most american states have flipflopped between Republican and Democratic multiple times in the last 160 years since the disappearance of the Whigs. (And the parties themselves have swapped positions several times during that space.)

Even a deep blue state like Illinois was under trifecta Republican control as recently as 1996. Deep red Missouri was under trifecta Democratic control from 1993 to 2000 (and has had Democratic governors for 20 of the last 30 years) and used to be a bellweather state.

The note in the corner is interesting, "Countries in this zone are very divided and doubtful that their differences can be overcome." Columbia is in that group and is 14th of 28 (from low to high) on the scale of "I do not feel these divisions can be overcome", putting them in the lower half of countries for doubt and below some countries even in the Moderately Polarized tier. The US sits at 17th, putting them also below countries in the Moderately Polarized tier.

On the other axis, Sweden has high doubt, but sits pretty close to the middle at 13th for degree of polarization, below some Moderately Polarized countires.

That might suggest that there should be a different way to group the countries when 1/2 of the severely polarized countries might not really represent the description of severely polarized?

Iowa is so high because there are only 3 public 4-year schools in the state and over 30 private 4-year schools. When you take the average by school instead of by student, that means that the more expensive private schools are going to drive the average.

This is also why the in-state and out-of-state are so close as most of the private schools probably do not have an in-state discount.

(Oregon has 7 public schools to 21 private. Vermont has 5 public schools to 11 private, but 4 of the public are considered a single system and so it might only be a 2 public schools for the purpose of this data source, even though all 4 have separate Title IV listings.)

It's not that the military code is high precision and civilian is not. M-code is just there to provide a standalone alternative to civilian band that is more resistant to jamming.

Differential gps and WAAS provide sub-centimeter accuracy with civilian bands.

Each state has a minimum level of training to be a license peace officer. That would appear to be what is in the chart. Beyond that, individual departments will have their own academies and their own requirements, as well as separate continuing education requirements.

This is part of why department certification is important. That certification has minimum internal standards for what the department must requirement and must teach in their own academies. Unfortunately, few US departments are certified (though most large cities).
