    TeX doesn't use lines, it uses boxes and there are some subtle differences in the concept. If your game, you can use METAFont to create paths and build boxes around it and then typeset in those that but it gets messy and it breaks the "does this look good" metrics. Its on par with writing in basic TeX without even loading the plain.tex macro set.

    TeX could be retrofitted to cope with modern fonts, but modern fonts (and many included with TeX) just don't have the proper kerning tables and other metadata to make the results look good. While there are some font designers working on that issue, their fonts tend to be the ones for European marketing and not describing complex math formulas.

    As far as that XML pixie dust that seems to be the drug of choice, Knuth proved that it is bad parsing before it ever even existed yet it grows more common every day.

    Did Toowoomba ever solve their waste disposal issue? If their plan ever happened, their filtered water would then be piped upstream where it would be filtered by billions of tons of rock in a natural ecosystem which is not much different than building a water plant downstream of a sewage plant the process that makes it safe for humans to reconsume involves other natural processes.
    Did you mean Gloucester as the city in the the UK that is using some wastewater for industrial use and watering parks? London also often gets mentioned.
    Tamworth is another that fits into the category of "they aren't doing it"
    There is waste water that is being used, just not directly back into a system for human consumption. Plenty of golf courses are watered with water from a sewage plant.
    There are several South African plants that I know about but none of that water is intentionally for use by humans.

    West Basin (and most of the others in the US including about 50 that aren't listed in that report): Typical Purple Pipe system in the US.
    UOSA: injects water into the biological active area of the river
    The table 6 shows 0 used as drinking water.
    Namibia... uses a massive algae pool
    Singapore: the main plant showing "its safe for humans". It costs them more than desalination but they make water for silicon industry and a trivial amount ends up in bottled water to be sold at the plant tour gift shop.
    Japan: recycle water can be used for some indoor use like toilets.
    Belgium uses a biological pool for at least 2 months.

    Can you name one place that intentionally takes sewage water and filters it and puts it back in the drinking water without a large natural process being involved? The novelty bottled drinking water from NewWater in Singapore doesn't count since it get cleaned up for semiconductor use before having some other minerals added and put back in and given to tourist of their plant. If you take human sewage and dump it in the ocean, the oceans chemicals will destroy any viruses and prions that made it that far. If you don't use a natural filter such as the ocean or billions of tons of sand and natural biological filters (like Singapore), your counting on absolutely no holes in two consecutive membranes which are stressed to nearly their bursting pressure for years. If you think mad cow is bad, wait until the results come out when someone is stupid enough to try what your proposing with blackwater. The lead and heavy metal content in the road runoff in Melbourne is so high that its cheaper to desalinate than remove the metals.

    Water tanks were removed because it they do bad things for river health and they are a major source of nasty things like malaria. I have seen very few water tanks aren't perfect for breeding mosquitos.

    Australia is running out of water due to incompetence. I have on my desk the Victorian Desalination Project IfEoI which appears to be written so that only one company can provide a solution. They keep talking 3.1 billion dollars yet the plant is only 4 times larger than the Tampa FL plant that cost $150 million. They also want to take the desalinated water and pump it very far uphill and far away to be stored yet the plant size will be able to meet the daily demands of the city which is all much closer to sea level. It cost $.035/kl to pump water up 100 meters based on current prices and assuming 100% efficient pumps. I have spoken to 3 companies that could provide a solution yet not one of them will be submitting to the local governments paper game since they are convinced they can't win. A billion dollar project is going to cost the average Victorian family about 1000 not including costs dealing with interest.

    The world does have CPUs that aren't x86. For some of them, adding a stack frame is adding numbers to the constants you use relative to the stack pointer. When you have to build a virutal machine to run 16 or 32 bit code on an old 8 but CPU there are other tricks as well.

    And according to the parser, that has nothing to do with the indenting, line spacing or in some cases the curly braces. My take on a code is it has to be understood at several levels and one of those is a higher level where such things are trivial all the way down to knowing that the sub brace has been added so they can put a extra variable on the stack. Remember in C the {} does mean "create a new stack frame" as well as grouping.

    Because what you might call a coding standard describing how to format a line of code just happens to be a trivially small piece of the pie. The core involves design and implementation details. I look at so many projects today that are never done. They all comes from a lack of understanding the basics. We tend to throw new languages at problems in an effort to solve the real problems yet more and more projects are late, over budget and never fully complete. My core coding standard is "write it in a language where it can be finished" which is knocking out more and more of the trendy languages since you can't complete a project if its core run time keeps changing. I have written a number of programs that are done. They don't get updated, they don't need to since they just keep meeting their requirements decade after decade yet statement formatting wasn't a major issue with most of them and the ones that it did were languages that predate the free form concepts like FORTRAN on punch cards.

    The T1s have lots of contexts so they can deal with running poorly optimised code that spends all of its time chasing pointers. A typical T1 CPU will run program 1, grab a pointer, try to load its data and stall from a cache miss but that switches to program 2 which had already stalled and now has its data ready so it can grab that, do a pointer calculation and stall again so the CPU is off to thread 3. The key to the T1 is there is not context swap between them. The T1 seems to very quick running poorly optimised ODD code but its a real dog running anything that has been optimised. Running hand optimised code on it is a waste of time. The T1 is the pinnacle of the solution "All problems in computer science can be solved by another level of indirection"

    The mob ties are interesting. It would appear that sometimes the local mob is the only factor with any civic pride who is willing put push the issue. I saw an article many years ago where someone researched the road construction in Kansas City during the mob rule there. It turns out that the city paid about 10% more for the roads built during that time than they should have. The big kicker is the quality of the roads built at that time was substantially better than roads built before or after and there appears to be some very impressive return on investment since. Some of the roads were still in great shape even though they had no maintenance at all in the decades wince they were built.
