> Their actual “job” is to make the most amount of money possible. That is generally true, but not of quasi-public utility companies. The government controls the price utilities charge, and could force them to invest in storage.

From your source: > this suggests an average of just under 18 trips per car every week. So cars on average are used multiple times a day. OP's claim that most cars aren't used is ludicrous.

Why do houses need storage? Why can't the grid operators do their job? Pumped hydro is a practical grid-scale storage solution that doesn't need lithium. [1] cost $4B for 24Gwh of storage. That's about the same as the cost of

> So what are the realistic options? Maybe the utility companies could do their job and provide a reliable electricity source, instead of outsourcing it to customers.

> Or better yet, owners set their car to only "bid" for a grid storage job when the cost-per-kWh is greater than the cost of degradation. It would have to be substantially greater. I'm not going to deal with reduced batter

This boils down to "There are lots of EV batteries, we can use them as storage!". It seems to ignore practical issues: People drive during the day, and charge at night. So you could use EVs as a buffer during the night, but they s

Very true! I wouldn't expect any blocking IO here (except for the first run). I would still expect the majority of the time be spent reading from memory vs CPU bound "number crunching". I should have been clearer. In my day j

I just did a very un-scientific benchmark to test this. I chose ripgrep as a conservative choice, since most of the time should be I/O anyway. I grepped for the word "Jesus" in a file that contained 100 copies of the king jam

Not really, no. We have evidence that even very low levels of lead is dangerous. The cost/benefit analysis is different. We have no idea what the "safe" level of PFAS is. Maybe its zero, like lead, but maybe not. Every sip of

Yeah, in the article they call a town with between 5,000 and 10,000 a "mid sized city". Completely ridiculous, IMO. People read misleading statistics that XX% of the population is urban, but that doesn't reflect reality.

I would love to see an actually fair comparison, where the native implementation uses io_uring and huge pages.

by dahfizz 4y ago
We already have things like io_uring to achieve this speedup. As usual, this benchmark is comparing against an extremely naive implementation. It even uses a non-optimizing compiler! A fair benchmark would take advantage of all the features

Its not unreasonable to point out that having your own car unlocks a lot of personal freedom and independence. That post is obvious flame bait but I find it hard to argue the underlying truth.

Every server I know makes over $20/hr in tips minimum. Double that on a busy weekend. And they don't pay tax on it, so its really more like $25/hr minimum.

I wish Linux didn't make managing huge pages such a pain in the ass. You have to "allocate" huge pages ahead of time by editing a file in /proc/sys before you can map the huge pages. Why can't free memory autom

Its literally one line of code, let slug = base32Encode( window.performance.now() ) Maybe 15 LoC if you don't want to import a b32 encoder. Hardly seems worth a dependency.

That is definitely taking the long way around.... Why not just grab a timestamp and base32 it yourself? ULIDs also use millisecond timestamps, and use implementation magic to sort IDs within a millisecond. If you are just using the timestam

by dahfizz 4y ago
If you are taking base32 as user input, you can translate '1' to 'I' so that the input is correct regardless of which the user types. But, needing users to read / type a base32 ID is always bad UX anyway.

I think people here are confusing "cook with" to mean either "the fuel source to cook" or "the oil in the pan to aid in cooking".

I'm not sure the economics works on something like that. Once you buy all the equipment, employees, and commercial buildings, it simply isn't going to be profitable to only run your factory 10% of the time (How often does solar po

How often do you need to scale up or down a printed document? I don't see how that is useful.

But you could upload a new program of movements on the same hardware. Requiring bespoke hardware for every possible task is like saying we shouldn't have CPUs - if you're gunna write a program, might as well put it on an FPGA.

Once you've taken VC money, its growth at all costs. Where "growth" is defined by inflating valuation, not necessarily "real" growth of the company. If you want to be frugal and grow responsibly, you have to do it w
