Enhanced recovery isn't carbon sequestration. You're not actually sequestering that much carbon with a C02 flood. That's not why oil companies tend to support CCS.

CO2 is only useful for enhanced recovery in a few scenarios. It only works in non-water-wet reservoirs, which are fairly rare. You wouldn't use it in other cases even if someone was paying you to. (You'd lose vastly more money in lowered recovery factor compared to optimal methods for the reservoir than you'd get paid. Better to use the correct methods and inject C02 into something you're not producing from.)

Big oil companies are in favor of CCS because they're the ones who can do it most effectively and have invested the most R&D in carbon sequestration strategies.

Like it or not, big oil isn't some evil mustache twirling villain. Yes, Exxon has taken some dicey moves with lobbying, but most of the oil industry has been very aware of climate change for quite awhile now and has been heavily investing in ways of tackling it (or at least they were ten years ago when I worked in oil - I assume that's still the case). They're basically waiting on regulatory changes to make it profitable.

The technical challenge right now is efficient C02 capture. We've largely shown that long-term C02 sequestration should work. However, we still don't have a ton of ways to capture carbon at scale that don't involve significant energy expenditures. The whole system needs to be carbon negative to work, and the methods we currently have don't scale terribly well in that regard. (i.e. Carbon capture is most feasible right now during electricity generation and other industrial processes that produce high concentrations of C02. To have a global impact we need to get it to work at atmospheric concentrations.) That's something that actually is a fairly tractable problem, it just needs large scale focus. To get that in our current system, you need to make it economic to capture and sequester carbon.

We, as a society, are still dependent on hydrocarbons for lots of things. We really still can't easily replace them -- we're structured around cheap fuel with a very high energy density. Electric cars certainly help, but they can only replace some uses. We just don't have the technology to replace a large chunk of our current hydrocarbon uses. It's an energy density problem.

You want to change something, change the regulatory system. Regulate C02 as a pollutant, sure. You have to be careful how you implement that, though, or you'll most heavily impact the most venerable portion of the population with price increases. For that reason, cap and trade is also a good approach. So are many of the carbon market strategies. Yeah, some of those ideas come from the conservative side politically -- it doesn't make them ineffective.

Vilifying oil companies just demonstrates ignorance of both the problem and the solutions. Big oil is part of the solution as well.

The SQLite creators have a great deal of documentation that's targeting database administrators and users and trying to explain what this thing is, when I think they really should have just targeted people who need a nice file format and a clean API.

> Casual users don't install an OS

Your definition is useless: it would just mean that casual users simply never use Linux OS at all, and aren't supposed to use it, as these with your definition also wouldn't have an awareness to specifically buy a separate computer with preinstalled Linux.

To make a definition of a "Linux casual user" in any way meaningful, you have to assume that it's somebody who would like to try to use Linux, especially without a specific desire to pay for a new computer for that.

Oh, and also without the specific desire and readiness to use command line having the ingrained assumption that the GUI tools simply don't work, which is relatively common case in desktop Linux, even with LTE.

By the way, my quote also shows what Ubuntu consider their casual user, based on the strengths they advertise:

"The latest version of the world’s most widely used Linux platform for Kubernetes, multi-cloud and machine learning."

I'd say, from their point of view, the target user on that page is, interestingly, somebody who needs but is undecided which Linux platform to use for "Kubernetes, multi-cloud and machine learning."

Which is also interesting, but also doesn't follow that such a person would expect his installed OS to have broken applications every 6 months because of OS experimentation in compositors or whatever.

> Have you tried to figure out where to install the server or asked what the system requirements were for it?

Not exactly, but asking "where to install the server & client and what are the system requirements for each" is not that different to asking "where to install the client and what are the system requirements for it", even when there is no server.

> Have you grown concerned that once the system moves into production the O&M team won't know how to operate "yet another database"?

Yes. Because the production concerns of SQLite are not nil.

> Do you spend agonizing hours trying to figure out if it supports multithreaded connection pools for multi-user writes?

Not agonizing hours, but it is just a slightly rephrased version of a valid question about SQLite w.r.t. concurrent file access (as with locks on file access for any file). Other commenters have brought this up in terms of multi-user access slowing down applications, and setting up intermediary DB access processes using IPC to facilitate this.

> The people asking these questions are stupid

I disagree

> no different than "CSV is serverless" or "JSON is server-less"

CSV and JSON lack any protocol or queryable interface: unless you're using some ancillary tool like `jq` as a comparison, CSV and JSON as filetypes are both "serverless" and "clientless" so not particularly comparable. An article on those would be quite different.

Reddit. It's still usable with a third-party app (Apollo) even though they completely slaughtered their web UI.
I was thinking about the same. If there are any affiliate marketing people in here, can you tell us more about your workload, RoI, setup and problems? :D
Sure, I can get behind that. The logic that handles the read/writing and SQL parsing is all part of the library for sure.

But that library is absolutely not required nor is SQL. One could build their own library that read/write to SQLite files entirely without any of that if they wished. Some people have done ground up rewrites in other languages other than C, but have more or less stuck with the same internal logic and the use of SQL as the read/write logic.

It absolutely is not hyperbole.

Any test that leads to unnecessary treatment is unsafe. That list typically includes anything with false positives. For example, excessive testing for certain cancers (like breast cancer) lead to higher death rates.

Here's a concrete example where poorly-understood genetic testing has led to unnecessary surgery, which is obviously not safe.

Alright, yeah, I pulled up basic formulas on profitability ratios to check my math:
https://thismatter.com/money/stocks/valuation/profitability-...

I've talked myself into: maybe 24% is technically "profit margin," but only because banks are weird and profit margin makes no sense for them.

If you have a grocery store and you sell $100 of fruit, maybe $1 is profit. It makes sense to say you have a 1% return on investment. $1 Profit / $100 revenue.

That makes sense.

But a bank loans out $100 at 5% interest. It collects $5 next year while the loan is still outstanding, of which $4 go to operating expenses.

That is $1 profit on $5 of revenue, so 20% profit margin, by the formula. But it took $100 to get you there, just like the grocer, so 20% feels inflated for basically the same result. (In other industries you don't sell a peach only for the buyer to later give you a new peach back, so that throws all of this off.)

(You raised ROE, which I think typically ROE for banks is 5-8%, and it's really dependent on random factors like how they treat shareholders, so you might be right? But I think we can set that aside too.)

So none of this makes sense and maybe I give up?

I can see why the industry just decided ROA is the measure here. It's not completely crazy, and seems to generate reasonable results relative to other industries.

And if we're really asking, "hey, I have $100, maybe was loaned it by a lender or depositors, and I can magically run a buffet or a bank next year, what do I expect to earn?"

Then yeah, we really want to be comparing the profit margin of the buffet to the ROA of the bank, as incommensurable as those sound. Maybe this isn't completely crazy and the industry lit has this already figured out in the most reasonable way.

Dear dang, please could you unflag my comment?

I am up for a debate, and I am happy to be shown other perspectives. Yet flagging my comment seems to be the easiest way to scrub something you don't like, while avoiding constructive debate. It seems to me that you are labeling my writing as starting an 'ideological flamewar', when I would argue I back up my arguments with leading research/references.

I just replied to another comment below, with more links: https://news.ycombinator.com/item?id=22153575

When I googled ‘flamewar’, wikipedia defines it as:

"a flame war is a series of flame posts or messages in a thread that are considered derogatory in nature or are completely off-topic"

I am making connections that I think are worthwhile. They might seem overly critical and negative to those who are not familiar with the arguments. Do you want to limit connections you don’t make yourself, and discard them as ‘off-topic’ because you aren’t familiar with the research?

That sounds a bit like cherry-picking to me.

I don’t understand how constructive critique like this can be flagged, and my comment muted/hidden. Are we not all humans typing away at our keyboards here? Is your perspective really the ‘right’ or only useful perspective?

The only reason I can think of for you and others to flag my comment is if my comments are getting in the way of you or others in Silicon Valley from charging your rents? Is it that you see some truth in what I share that you might not be comfortable with?

this is all assuming that with nation state resources they can identify use of VPNs at the user level.

That's not something we have any control over, is it? Whether it's allocated to internet or some other channel, these companies are going to advertise to acquire and retain customers, and that advertising cost is baked into their prices.

Useful, but one thing: a USB-3 port can be compatible with a USB-2 port, so one might expect that 2 USB-2 ports can also be covered by a device with two USB-3 ports (as long as they have the same connector), but I don't think the search works like that.
