All the functional checks are done in the producer and consumer client code - the only thing any Confluent hosted tier does is check to see whether the schema-encoded Kafka message contains a schema ID that matches one for that topic, it does absolutely no data validation otherwise.

So, if you have a bad client, you can publish data to a topic which does not validate against any schema, but the topic will accept it so long as the schema ID presented is valid. The entire thing is based on trust.

You can do much better validation than their implementation, essentially, and lose nothing.

It's important to note that over the last 15 years, cumulative U.S. inflation has been on the order of about 45â"55% depending on which exact months you choose and which price index you use. College prices have risen faster than inflation but everything is more expensive too.

The library is most likely benefiting from volunteer labor to run the program and take care of the machines. The university has to pay someone for that. Completely changes the way the services are offered since there are real costs of labor.

Comment Re:18 Inch Tsunami? (Score 1) 28

I mean, it depends on exactly how fast the water is moving (as well as how deep it is; both things matter). If we're talking normal river current (say, 1 foot per second), most adults can stand in eighteen inches and be fine, if it doesn't catch them off guard. If the current is faster, then it doesn't have to be as deep to have essentially the same effect, or if it's deeper, it doesn't have to be as fast.

There are of course some caveats to the above. One is, once you get past about 4-5 feet deep (depending on the person), you're floating or swimming anyway, so additional depth doesn't matter very much at that point; but additional velocity still makes a difference.

Not just Kafka, but also stream processing of Kafka originated data.

We use it to run a cities public transit realtime data system (track vehicles, display information on realtime maps, public information displays, make predictions), and it works well - there are features which I think are snake oil (schema registry for example), but its been rock solid, performant, and the UI is decent.

Oh, forgot to mention I'm from the Midwest. There's no room in the garage for a _car_ of all things, haha, that would be ridiculous. No, the garage is where we keep the garage stuff. You know, the lawn mower, snow blower, garden tools, step ladder, extension ladder, bicycles, sawhorses, sports gear, extra bricks left over from when the patio was put in, spare pieces of plywood, hedge trimmers, mattocks, old paint buckets, hula hoops, bungee cords, antifreeze, grill, charcoal, lighter fluid, and so on and so forth. There are four people in this household, so the garage is pretty much full. It think there might be a cheap plastic imitation of the Amulet of Yendor out there.

Web search is trending on a path similar to TV. At first, TV was free with no ads. Very quickly ads were introduced. Then came cable TV where you could pay and watch ad-free. Fairly soon after that cable TV had ads too. Then streaming did the same thing. The quest for every-increasing profits will have the same end result for paid search, eventually.

Your conclusion isn't wrong, but your supporting argument suffers from selection bias, confirmation bias, and a really small sample size.

Among other things, young people are overwhelmingly more likely to be interested in academic topics if their parents also were (and you can spend arbitrary amounts of time arguing nature-vs-nurture on this; my conclusion is that it's both, and they're usually in synergy with one another on this issue), and statistically that means they are overwhelmingly more likely to be interested in academic topics, if their parents have enough money to *buy* their kids things like books, magazines, and subscriptions to learning-related services (CrunchLabs, Curiosity Stream, Brilliant, etc.) Statistically, the majority of public-library users are below median income, and they're in the public library because it's affordable. Children from lower-income households, statistically, are more likely to check out a video game or a movie, than a book, unless they need the book for a project that someone (usually a teacher) is _requiring_ them to complete (and sometimes they don't even bother then). The kids who enjoy learning, *tend* an awful lot of the time to have access to information that is not dependent on the public library. Though of course there are exceptions. And sometimes there are people who *prefer* to use the public library for ideological reasons, even if they could afford to be independent of it; but such people are in the minority.

For what it's worth, I'm in the same camp as you, someone with a fairly academic bent who grew up relying heavily on public, free sources of information, especially public libraries. My dad had a graduate degree, but it was in a field not known for large salaries; my mom, who is no dummy but doesn't have a bachelor's degree, was actually the primary bread-winner throughout my childhood. (She attended a hospital-run nursing school, back when those were a thing, and so was a registered nurse.) But, statistically, we are in the minority on this.

With that said, it's absolutely true that lack of interest in information, is a much bigger problem than lack of access to information, in the modern world, especially in the developed world.

You:
> I need my system administration routine down around 30 minutes per month.

Also you:
> I want GUIs for all common tasks

Yeah, those are *fundamentally* incompatible goals. Doing system administrative tasks using GUI tools is always going to take a lot of extra time, because GUIs aren't really scriptable. I mean, yes, you can use fancy window-manager features and macro toolkits (like xdotool or whatever) up to a point, to recognize certain windows and automatically click certain things, but this is inherently brittle and high-maintenance, in addition to taking a *lot* longer to set up, than throwing a handful of commands in a script and calling it a day.

If you're doing system administration in a GUI, it's going to be more like 30 minutes per month *per major service* that you administer. So 30 minutes a month for the web server, 30 minutes a month for the RDBMS, 30 a month and sometimes more for the mail server, 30 minutes a month for the firewall, and so on and so forth. If you want 30 minutes a month total, you need something you can easily script and run on cron jobs, and that means command-line tools.

GUI tools seem attractive when you're new, because the learning curve is lower. But it's a trap. In the long run, they will continue demanding large amounts of your time month after month, year after year, decade after decade, until you finally get fed up and kick them to the curb.

They also get in the way of building homes.

For a while (no idea about current situation) but where I used to live in the UK you could not build a property because the Environment Agency had enacted new rules which capped water run off into watercourses, and no council anywhere in the UK had manageable plans to actually meet it with new developments, so nothing got built.

The rules were well intentioned, but came down like a hammer and stopped everything.
