I’m a griddy customer and am still happy with the service after this past week. Griddy is not for everyone not by a long shot but I think it’s getting unfair press on this past week.

As a Griddy customer I wanted to share some additional perspective:

Griddy’s app provides real-time prices as well as the projected prices for the next couple days.

During the past week i was getting notifications every five minutes on the current price.

Their interface shows your daily energy usage in terms of kwh as well as price.

The whole point of being a customer at griddy is to reduce power use during spikes. They do a great job providing data on when you need to reduce usage. It’s in their interest for customers to have this data. As far as i can tell they only make their money from the $10 monthly fee. High prices don’t help them.

In the end we essentially unpowered everything. We charged phones, left our modem/router on and kept our gas furnace set to 59. With blankets it was fine for us and we knew this was a possibility going into this plan (minus the extra difficulty of covid)

I think it’s disingenuous to have these articles about high bills without providing how much energy they were consuming and what they were using it on. Even at $9/kwh a $9000 bill would more energy usage in a couple days than we have in a month or more (we live in 4 bed house)
> its not like those fields teach about childhood development.

I agree, Pedagogical science fits in STEM and I think it's very important we deeply invest in childhood development. I mostly think the subject matter of school is questionable, not the fact we go to school (hence why I suggested we also fund STEM degrees for anyone smart enough to finish it)
Program synthesis seems like the most promising area of research for that—treat compilation as a search problem or even a series of search problems rather than as a pipeline of (mostly) deterministic steps. Couple a compiler with search-based optimization, some kind of lightweight verification and a more interactive interface with the programmer and you have a programming environment that can aggressively use today's powerful compute resources to provide a qualitatively different experience.
No its not - If you read the article

> The Common App’s data does not include community colleges because they typically allow anyone to enroll. But those schools, which often provide low-income students a first step into higher education, also saw steep declines. In the fall of 2020, freshmen enrollment fell by more than 20 percent.

The two trends in the article are a 17% increase in applications for the most selective institutions and a 20% drop for community colleges.

The Times uses weasel words here

>some selective schools saw big increases from students who are typically underrepresented at elite institutions. The University of California, Berkeley, received 38 percent more applications from Black, Latino and Native American hopefuls than in 2019.

Meaning only some selective institutions, the Berklely increase in applications was because they waived the standardized test.

Knowing application patterns this is bad news - it means that poorer people, especially undergrads have not applied this year.

It is unlikely that those same people just turned around and applied to Cornell. I argue that the increase in apps to elite institutions is from people who left the workforce from good jobs. They are making a strategic move to weather the COVID storm and come out on the other side better off.
I've never seen any references to any Lisp work without symbol interning. I suspect MacCarthy had this idea before any code had been written.

I also suspect that property lists came into being organically as part of incremental development, as follows.

Initially, symbols would have had some built-in storage fields, such as a place to store a function or value.

As development went on, the researchers wanted to attach more information to symbols pervasively. In the system itself, they waned to indicate whether a function is in machine language or in Lisp. Plus, likely, there were situations in which it was desirable to attach application-specific data to a symbol (that is not simply its value).

At that point, the idea would have been obvious: let's not make symbols any larger with more fixed fields that waste memory, in order to represent rare properties that only a subset of the symbols have. Let's attach a dynamic list to them with variable properties. Since not all symbols have all properties, the properties cannot have fixed positions in these lists, which requires associative lookup. A symbol with no properties at all wastes only one storage cell to represent the empty list, which is the last such cost that has to be paid to support any number of properties.

Single examples don't refute the statement that many poor rural areas are quiet. However, if many poor rural areas are quiet, then the assertion that quiet is a luxury is contradicted.
No one knows. That's not public information.

It doesn't take into account that at 400 shorting GME became a much more appealing idea than even at 20/share. Everyone knew 400/share was unmaintainable.
Do what every other state does and not leave an essential utility to survival up to the free market? Texas is the only state that has this problem and it’s the only state with an independent power grid.
You could already own land, houses, cattle, ownership shares in companies that produce useful goods other humans want, all things the government doesn't control. If the concern is the government could potentially seize control of those things, sure, but a sufficiently malicious government can seize control of you and no amount of magic numbers on a USB stick is going to stop them.
Very cool and interesting that the green pentagon clock had several images of non pentagons. It’s getting the general flat sides correct, but not counting the number of vertices.
FWIW, I accumulated a bunch of docs writing resources while rewriting the Redux core docs tutorials last year:

https://github.com/reduxjs/redux/issues/3609

I specifically recommend Divio's "Documentation System" structure, and the Vue docs "Writing Style Guide" section as being particularly good resources:

https://documentation.divio.com/

https://v3.vuejs.org/guide/contributing/writing-guide.html

And here's one of the new tutorials I ended up writing, which took inspiration from many different sources:

https://redux.js.org/tutorials/essentials/part-1-overview-co...
It is a number set by Texas law as the maximum price of electricity [0]. The arguement that the commision used to justify staying with the maximum price seems straightforward:

> At various times today, energy prices across the system have been as low as approximately $1,200. The Commission believes this outcome
is inconsistent with the fundamental design of the ERCOT market. Energy prices should reflect scarcity of the supply. If customer load is being shed, scarcity is at its maximum, and the market price for the energy needed to serve that load should also be at its highest.

[0] Actually, there are 2 maximum prices, and $9/PWh is supposed to be the greater of them. Due to the high price of natural gas, the "lower" maximum turned out to be more expensive, to the commission waved the rule that would have switch to using the other maximum.
I'm not sure that's actually true, given how common software security vulnerabilities are.
If you have enough money you can move to a good public school district or pay for private school. If you are poor you must accept the monopoly school in your district - that is the rule.

I myself enjoy having choices for myself and my children but that is a consequence of money. This is why I support school vouchers - let parents determine how to spend their money, and let schools compete for students.
This case stops short of proving exactly what percent they are currently backed at - there is almost certain some level of "legit" deposits (Tether has value in evading capital controls). The weight of evidence is strongly in favor of past financial crime, and the imposed transparency requirements suggest NYAG suspects these issues are ongoing. I dont suspect they will ever provide satisfactory evidence of legitimacy, and the DOJ is almost certainly investigating them by now.
If more kids get into STEM, then eventually STEM salaries will regress to the norm.

Have you ever had a manager who helped you achieve heights you hadn't imagined? How about a manager who made your life miserable?

I've experienced both. Your manager is critically important to your career and to your overall happiness. Our mission is to elevate managers to maximize the success of their teams and organizations. We envision a world where everyone in the workforce is deeply understood, supported, and empowered to reach their goals.

We live and breathe our own product and are looking for people who want to grow and be heard!

Women and underrepresented groups are strongly encouraged to apply. See full roles at https://risingteam.com/careers or email me at jeff@risingteam.com.
Thank you. I've been trying to be open to that possibility but so far it has eluded me. I really appreciate your compassionate encouragement.
In the early 70s I was part of an experiment that did just that. We were one very large class of grades 1-6. Older kids were assigned younger ones to mentor.

I was in it for two years; it was a really good experience. As for the outcome, all I know it wasn't broadly adopted.

> Moreover, it's a lot easier to learn CS on your own or on the job. ;-)

HackerNews tradition requires that I point out the considerable difference between software developer skills and knowledge of computer science.

Coding experience doesn't give you what a degree in computer science gives you, neither is a degree in computer science a substitute for experience as a developer.
Strong agree. This is a lazy polemic. Take, for instance, this one amazing part:

> Goldman Sachs, Citadel, Andersen Horrowitz those guys are making transaction fees

"Andersen Horrowitz"? Does the author have any idea who he is criticizing or what industry they're in?

> Failing microcap stock

GME is not a microcap stock, and it was not a microcap stock, even before this entire saga

> I make no pretense that I don’t despise the bitcoin philosophy

Erroneous double negative here, does he even proofread his own work?

Somewhere in here he states that "Bitcoin doesn't work". I've seen a lot of lazy criticisms of Bitcoin, but this one just falls flat -- of course it works. Say what you will, but the entire system works with continuous uptime, the ability to transact, etc. etc. That's why it's worth a trillion dollars.

Saying that you don't understand how bicycles stay upright doesn't make them fall over. And similarly, saying that Bitcoin doesn't work, well, doesn't make it stop working.

I think Griddy sounds like an innovative service, one I'd consider using if I had the equipment necessary to drop off-grid when prices are high.

The problem is that they sold it to people who didn't understand the risks, and if that weren't the case, they would probably have too few customers to support the business model.

I mean, greater brevity in theory, but having used both s-expressions and JSON for config files, I can tell you that the s-expression version ends up noticeably less verbose and noisy in practice.

> This despite the fact that that notation is decades older than almost every other syntax out there and yet still lost the popularity contest.

Beyond some minimal level, quality and popularity aren't all that heavily correlated; something not becoming popular tells us almost nothing about it.

For solo development? I don't think it's good, but ultimately you should do whatever works for you. When you work on a team, though, it might be hard to break the habit later if this is what you're used to, and you really really will need to. Nobody wants to see "snapshot" commits in a shared repo; commits will need to actually accomplish a clear goal. Also, I find it very helpful to be able to make independent changes in separate commits (sometimes I see something wrong that's unrelated to whatever I'm doing), then reorder (rebase) them to polish them sometime before pushing. If you don't get in the habit of making your commits somewhat orthogonal, you won't be able to do these kinds of things (whether on teams or solo).
Your own initial comment in this thread was about AWS kicking social media platforms off of their service. That is what I am responding to.
> Free speech is a sign that your society is strong, peaceful, or successful, because it doesn't need to suppress subcultures or ideas by force. That suggests that the society is built, if not on consent, at least not on hiding something or getting people to pretend that they agree with things they don't.

In the U.S. we heard a lot about this idea during the Cold War and also during earlier days of tensions with China. Something like:

There's a conflict of these civilizations going on. How do you know which is right? Well, presumably the one that's not afraid to let you hear the other one's narrative or opinions. The one where you can buy the other one's newspapers if you want. That one doesn't have anything to hide, while the one where you can only get access to the local government's view of things presumably has a lot to hide and a lot to fear.

(However, I no longer think this distinction has been as clear-cut as we think. During parts of the Cold War, the U.S. government did a lot to reduce Americans' exposure to Soviet media or messages, or to stigmatize or deter in various ways the advocacy of the idea that the Soviet Union was right or that its system was better. Present-day Americans are also pretty concerned about Russians or others telling us things that we might find internally divisive. Some of these concerns are mediated by the idea that propaganda is bad or of no particular value if it is either false or conceals its origins, which might be approximately right, although the U.S. government has not consistently accepted either of those as ethical constraints on its own propaganda activities, and some recent American discourse has also evinced a surprising level of similarity to the Chinese idea that true information, or sincerely expressed ideas, might sometimes be bad for a society just because they are disruptive or divisive for it and not because they constitute lying or misrepresentations.)

(I also noticed that both North Korea and South Korea have laws prohibiting receiving or spreading propaganda from the other Korea. Even though I think it's obvious who has more to fear from the free flow of information across the Korean border, the symmetry in this legislation seems to show a lack of absolute self-confidence on the South Korean government's part...)
They do to a degree. Nobody's going to court over a $200 bounced charge that you could argue shouldn't have been there in the first place. Most services will just close your account and move on with their lives.
Youtube is/was disk killer for some reason. Used to listen a lot of music from it, but the constant heavy disk usage put me off. 16GB on Linux, zero swapping, Chrome browser. Switched to old school MP3 playing via Audacity and never looked back.

You can see what is wearing your disk under process / activity manager.

The M1 behaviour can it be Chrome + Youtube,Netflix,Spotify usage related?

> 8GB of ram isn't a lot.

True, my 3 year old phone has 8GB ram. On a laptop, 8GB is just anemic.
>Second, the distinction between normative and descriptive statements, as you define them, is not always clear-cut.

True but does not matter. Those statements, that fit into the descriptive/normative categories are the key ones of any text, the rest is either allusion or up for the courts to decide.
IMO phrasing like "looks like there might be voter fraud" would not have let to the storm of the capitol.

>"I think all <insert group> are criminals"? Note that the "I think" was implicit in your phrasing

The difference of normative/descriptive statements is the same as subjective/objective ones. "I think ..." already started subjectively and can only have a descriptive component, if its backed up with a statement like "because X is ...".

>"Donald Trump is a criminal."

>The US approach to this is to generally try to avoid having the government be the arbiter of truth

But courts decide who is a criminal or not. And when such a decision is made, you could legally call Trump a criminal.
Experts are frequently heard in court to distinguish it, so why not extend it? It does not have to the ministry of truth (political) but we all require the authority, that tells us the way things are, hopefully in an unbiased way.

They are not 10 to 20 years ahead of the curve. The Sampo and Satori generations are very much in the same age bracket as Western millenials.

Stagnation and resignation has also been the answer for millenials in the West. If by revolution you mean the recent Capitol riots, most of the protesters were over 40 and well off. If anything I'm surprised by how politically apathetic this (my) generation is.
Companies absolutely are looking at how good the CS program is at Keene State College.
Yes, you can have multiple reviewers.
> If someone is ideologically possessed, they will use these tools to skewer outgroup ideas but not apply them to ingroup ideas.

Not just that, but ideologically-possessed people will flat-out reject a truth-finding methodology that results in conflicts with their worldview.

There's no point in giving someone the tools to find the truth if they're so wedded to their "truth" that evidence will not make them change their minds.
I think Tether is mostly a fraud, but the market for escaping capital controls (aka money laundering) is almost certainly $30B/year or more.
> no incentive to save

I highly disagree with this. The S&P 500 has returned 400% since the crash in a mere 12 yrs. If doubling your money every 6 years does not sound excellent to you, the it's a financial education that is lacking, not real opportunity.

> in-person communities are fractured by many different spoken languages

I actually have found this really enjoyable, to have lots of opportunity to speak/learn Spanish.

> cultural promotion of pornography, sex, and drugs.
Given how these affect the reward centers of the brains, IMO these should all be reserved as post success rewards. If someone wants to smoke weed all day and do nothing, that sucks. But if they're high achieving and want to relax _after_ killing it, who are we to tell them no?

Branding everyone who disagrees with you a white supremacist is not a good way to win supporters to your cause.

I encourage you to de-program yourself by paying attention t what those who have different opinions have to say about their experiences.
I wonder if this works for efferent behavior too. Perhaps when throwing a rock, we actually throw it a thousand times in our brain before letting go of it, as feedback from our muscles converges with our perception of ballistic forces. Like running a thousand simulations and picking the best one, as the event is happening.
It's not. My MBP (non M1) has 28,891. The battery would be dead as a doornail. I imagine MacOS just has the ability to put the SSD to sleep when idle.
Neat, but it honestly feels like a step backwards for me. I don't pass multiple parameters into print() or console.log() for Python or JS. I use f-strings in Python 3, .format() in Python 2, and template strings in JS. They just read better to me.
Beaglebone is even worse, with a PowerVR GPU and blobs to make the PRUs work correctly.

It's pretty difficult to find a device with completely open drivers, let alone open firmwares and memory initialization.
It's not far off for graduate jobs already.

Unionization will fix this. A glut of STEM candidates will not.
Wow. How long ago did you get the MBP 16"? I've been running this system as my daily driver for >12 months and see very different numbers from you:

hopefully tomorrow is in 2021, regardless of time zone or day and month.
Yeah, but that's only because retail investors got locked out of the market at $400. The clearing houses spontaneously jacked up collateral requirements for the stock and almost every broker either locked investors out of trading or explicitly banned additional purchases of the stock.

You can actually compare the timings and see that the second this happened the price imploded.

If the market didn't lock up like that the shorts would have been completely annihilated. The populist play was a good one, but they we're playing a rigged game and the buyers found that out the hard way at the 11th hour.
I'm fine with the norm. The norm is better than losing all hopes or a bleak future. The norm is a job that pays ordinary salary but gives me hope that I sharpen my skills and get rewarded accordingly (no guarantee, of course, but there's hope).

I'm grateful that STEM pays so well nowadays, but I don't mind if my pay goes back to norm in exchange for many people having a better future. I don't see the current K12 system will help, though.

Insights on how Pfizer protects from potential vaccine-related lawsuits
Ain't even the market mechanisms themselves that drive the high prices; rather, it's what those market mechanisms track.

Transitioning from land prices to land rental values - i.e. gradually moving toward a 100% land value tax - would address both high prices and scarcity by taxing land consumption - and, accordingly, encouraging urban density in order to amortize that tax, thus alleviating scarcity and reducing residential expenses. Same market at play (a land value tax definitionally taxes the market value of land); vastly improved outcome.
