  • 'Tis a great question and one very worth digging into. First off, I suggest getting The Big Thirst from the library. It’s a great book describing the challenge of water for several cities across the world and the processes used to make your water safe.

    Second, I’d also suggest checking out some YouTube videos like this Animagraffs video: https://www.youtube.com/watch?v=KsVfshmK0Ak. As The Big Thirst and others describe, there are a plethora of engineering techniques now to purify water on a citywide scale, and it is very much up to local utilities to decide how they do it.

    Third, someone has already pointed out that there are water quality standards in N. Ireland. As others have noted, it needs to be “safe,” not “sterile.” Indeed, you actually do want some minerals in your water—otherwise it can be detrimental to your health. Drinking straight distilled water continuously, for example, is problematic because “pure” water will actually leach the minerals it encounters.

    Fourth, the purity of water is ultimately about how much money is invested in purifying it. Chip companies and scientific endeavors need higher levels of water purity for some of their processes. This can be achieved through the engineering processes mentioned above, producing incredibly pure water—which is actually dangerous to drink.

    Lastly, the purification of water from your swamp is a function of how much money the city is willing to spend, but it is feasible to take nearly any water and make it safe to drink with enough investment in infrastructure. As part of this, the pipes that deliver water to your house are crucial: they must remain full and pressurized (pushing clean water out, not allowing contamination in). I mention this because it’s important to understand that the infrastructure around water delivery is nearly as important as the treatment itself. (Similarly true for wastewater.)







  • A dishwasher has two major cycles that are relevant to dish soap. One is the I’ll show about 15 minutes. And the there is the main wash, which is like an hour plus depending. If you don’t use powdered dish soap and split it up then you’re missing the advantage of the prewash.

    Second half is focused on the effect of heat and why you should drain your water line of cold water through your faucet before you start your dishwasher. By doing that, you increase the heat and you increase the longevity of that heat on is that are in your dishwasher. It’s worth noting that heat is good for dishwashing liquid both because it helps the enzyme break down and also probably breaks down with the food material at some cases.

    Beyond that, he was very enthusiastic about his new soap, which he helped create, and rightfully so. Double blind test, it came out very well against premium pods, and he was able to prove his whole point about pods not being useful in a prewash.

    To quote from a paper on the topic of OS security:

    https://iststudentlab.uap.asia/student-exhibits/periodicals-on-advancements-in-operating-systems-and-networking

    According to the paper [5], windows is the most user friendly and has more hardware compatibility. In terms of security, Linux is the most secure among all OS given that it is an open- source operating system which gives users the ability to customize and implement security patches. As for memory management, macOS is the better option due to its fully integrated virtual memory system which is often on and continuously provides addressable space up to 4 per process. The virtual memory system allocates extra space for swap files on the root file system as a program uses space.

    All available OS offer some level of security features such as firewalls, antivirus software, and encryption [6]. macOS has a level of security due to its unique operating system designed specifically for Apple devices with no third-party developers involved. Linux, being open source, is often regarded as more secure than Windows, which is a target of many malware attacks [7].

    Have you used windows lately? I swear it’s become half-assed as an OS. Might still have the enterprise management features, but it’s incredibly painful in a mixed enterprise environment that is not standardized office boxes. (e.g. science equipment). I avoid it like the plague if at all possible due to it’s now quirky nature.

    I’m dating myself, but at least NT didn’t crash all the damn time when you access a share on a NetApp or install a new version of the evil Java… Etc.
