From what I understand that does not really work. For example, you can't have jet fuel manufacturing based on negative prices, because you need to have high utilisation rate for manufacturing equipment itself. It's not economically viable to have that equipment sitting idle during times of normal electricity prices.

> The other day I installed an app in Linux that logs my activities

May I inquire about the name of this app? Is it desktop-environment specific?
wow, this is wonderful, SaaS for the people and not exploiting or selling their information! I'm in awe.
It feels like open source, what other industries can be disrupted, in this with help from devs?
Brazil's First CoronaVirus Vaccine
I completely agree. This is a bit of a process though, look at how Texans with variable rates responded to extremely high (90 times normal rate) prices: some just said f*ck it and managed to use 10-20K USD electricity in a few days.
I had a handful of go-to car services in NYC prior to Uber/Lyft. Just put their numbers in speed dial, talk to a dispatcher and the car is there in 10 minutes or less. And they were doing this with a handful of people who barely speak English out of a garage in central Brooklyn. Running a global business is hard, but providing services to 1000 local businesses isn't.
Ancient rectangles with pictures of fruit have been unearthed. The rectangles are believed to have been part of a religious ceremony of prayer and reconcilliation with the Ancient Server Pantheon of gods to sumnmon the growth of fruit-bearing trees. It is not known whether such "trees" actually existed in the past. Most scientists believe that "trees" were figments of the primitive imaginations of our ancient ancestors.

The purpose of the archaic rectangles was discovered after GhI, the student who had unearthed them, accidentally spilled a simple solution of quarks from his shirt pocket, mysteriously powering the rectangles. Upon powering-up, the rectangles displayed previously unknown hieroglyphs. The heiroglyphs are under investigation by the CIA, which is believed to have secret information on the glyphs, due to the CIA having existed since Neanderthal man lived.

The lead archeologist, Dr. XyZ of Mars University, noted that this sort of amazing technology is, "outside of our current understandings of the universe and cannot be dupicated with our current level of knowledge". To the derision of his colleagues, Dr. XyZ immediately called a news conference with the Free Peoples of Mars, Venus, and the 1000 Satellites of Love. At the news conference, Dr. XyZ stated the rectangles and the Server Pantheon prayers had been used to create the giant rectangles which reach to the sky in the ancient cities. The Empire CIA Building is the most famous of these sky-rectangles. Dr. XyZ was immediately fired from his post.

I have a lingering suspicion though that the cross connector pads, despite looking identical, serve their own specialized functions and cannot be freely mixed. I.e. it would be highly challenging to have all the pads accept USB or HDMI.

> Out of curiosity, what can go badly? They offer a counter and then fire you a couple months later, after they've found a more "loyal" (or just cheaper) replacement?

Definitely they question loyalty. In general all companies have an expectation of loyalty from employees they will throw away at a moment’s notice without any remorse

I leave jobs for two reasons: abusive employers/coworkers ot money. Because of this I would never accept a counter-offer, obviously I wouldnt stay in an abusive alsituation, and if another company sees me as more valuable than my current employer then the fear of losing me won’t change my soon to be former employer’s view.
I would rather be dead in a ditch than set foot in one of their cars. Because I expect it would be basically the same thing.

Their website has thousands of words about how horrible Uber and Lyft are, but not one word about how they are going to approach trust and safety. I really hope there's an experienced labor marketplace executive in the room who knows anything about this business, rather than a bunch of drivers who decided to run one of the riskiest operations for personal safety that one can imagine (there's a reason why parents don't allow their kids to get into cars with strangers).
Seems like those department heads are bad at scaling up their department's services to adequately utilize the resources at their disposal. They're probably arrogant pricks who make everything flow through them anyway, meaning they're the bottleneck that caused the slowdown in the first place.
I'm curious if you're trying to highlight the wisdom or dramatic aspect of the Perl initiative that's the subject of the OP.

----

If you're not intending to highlight either of these things, then I suspect you perhaps haven't understood the OP.

Perl has long had features that Perl folk consider better than Python's equivalents -- the issue you raise ('strict' lexical scoping) is an exemplar -- but Perl as it currently is has these features switched off (in the name of backwards compatibility).

The proposal in the OP is that Perl folk will consensually agree on which of 30 years worth of accumulated advances in Perl to switch on by default, and then newbies will automatically get that improved Perl by default.
The difference would be in the hyper-visibility of the deaths.

To show what I mean, compare the level of reporting and political backlash from [1], involving two construction workers against [2], involving 11 other deaths, that were only revealed after an audit. Visibility matters. I don't think it's unfair to say that if any deaths happen here that there would be far more global visibility than [1].

And besides, it's a silly armchair idea that doesn't make any sense whatsoever after ten minutes of scrutiny.

A few people in this thread are talking about electric heating being awful. And yeah, I think traditional electric resistance heating is expensive and not very high quality, but modern electric heat pumps are one of the most efficient forms of space heating we have, they can be run in reverse to cool houses too, and they increase comfort a lot — many systems allow you to have room-by-room control of the temperature. Plus they're used everywhere in Asia already.

Here's an example of someone's experience installing and using a "mini-split" heat pump for their house: https://www.sustainablelafayette.org/single-post/home-electr...

> Name calling only reflects rather poorly on you

I wonder what name you think I called you, since I didn't call you a name.

> Of course the article is trying to induce shame

Okay, Captain Crazy. (there: that's what name calling looks like)

> “Throwing the word "lying" into an argument like this counts as name-calling and flamebait in the sense that the site guidelines use these terms. It leads to distracting, shallow, and therefore more boring conversation. Would you mind reviewing the rules and please not do that?

So, this is also crazy, but interesting. I noticed in the above thread that Richard accused a git feature of "lying," which is something a sane person would not take personally, and you absurdly accused him of lying, and apparently you view this as somehow a useful tit-for-tat instead of the terrible behavior it is.

But this is delusion. I didn't use the word lying at all, so I wonder what the heck you're even talking about. It's not your honesty or lack thereof that is striking or interesting enough to comment on, it's your bizarre defensiveness about features and documentation, to the point of attacking people who certainly mean well.
If there’s no force behind the law then it’s just a suggestion
If "they" can include or omit "hallmarks", so can any other "nation state" operatives. In other words, this whole idea is complete bullshit, as it seemed to be when I first read it?
I'm not sure how valid an argument that is. If the Scotts didn't sell it, consumers would just buy it elsewhere. As non-fossil picks up, the demand and profit will just go down. Perhaps it's actually better to have the Scotts pump it up and transport the products to UK houses than getting it from across the planet. And oil is more than something you burn: the plastic itself is actually a carbon store (less CO2 to go in the air), we just have a problem keeping it out of nature and the production process needs electrification iirc (maybe there are also GHG byproducts, I don't recall atm).
ooh this is serendipitous, I'm going to need to do some deep research into term rewriting soon.

mentally, I'm modelling term rewriting as a state space search where each edge transition is a single possible rewrite. As always with state space search, the goal is to find the global optimum.

It's funny how many problems come back to search heuristics.
On the Google Play Store, they have app IDs com.driver.coop and com.rider.coop. I figure these should be coop.drivers.driver and coop.drivers.rider. This suggests to me that Google aren’t verifying domain ownership in app IDs, which I find a tad surprising. I had just assumed they would, and thus that you could trust that apps on the Google Play Store with IDs like com.example.foo or io.github.example.foo were actually from whoever ran example.com and example.github.io. That sounds like a mild phishing opportunity (only mild because I doubt most ever notice app IDs).
> So I have no idea what you're talking about.

Then you should also read the sentence directly after the one you quoted, in which it's explained:

> > The equipment that sits around waiting for low or negative electricity prices represents locked up capital, and ongoing maintenance and depreciation costs.
Hashtables are probably more directly useful than all the binary tree gymnastics.

The K&R C Programming Language book has nearly the same example (although I recall it using linked-lists for hash collisions and not probing).

I would be mildly suspicious of anyone claiming to have a recent CS degree who wasn't familiar with the ideas.
Also, looking at the article, they are quite complex! It looks like handling emojis in a proper manner has a large investment and the payoff is somewhat small.
Where are they getting "petabytes" of daily data from? Even if you took every single transaction anywhere near the industry, in all its details, and represented it in a verbose format like JSON or XML, that's still only kilobytes of data times billions of transactions = terabytes.

If they were gathering tons of video, maybe. Or vast numbers of high-precision sensors generating data continuously. But I didn't see anything like that.

It's just hard for any human activity to generate that much data. Is "petabytes" just some kind of hype, or is there something I'm missing?
It's not 'corrupt' to spy on other nations and it's not 'corrupt' to facilitate it.

It's not rooted in 'insecurity of the belief in a style of government' it's rooted in basic security measures. Western nations spy on other nations as a matter of national security policy much like they invest in early-warning satellites.

The 'corruption' stems from the type of authority that drives the activity, their motivations, and what they do with the power.

Monitoring is in place and usually it is caught in time. Downtime is acceptable in this environment, I don't think its worth being woken up in the middle of the night when it can just be resolved in the morning.
Any perspective is usually purely idealistic and strongly influenced by the environment you were educated in. We tend to consider the theoretical aspects of democracy as the golden standard but ignore the practicalities of the implementation.

So as we take the idealistic approach, any hacking campaign lead by Western intelligence agencies or any initiative to weaken encryption are for most people "pure" in intentions, they're anti-terrorism, they're fighting pedophiles. But any enemy doing the same, China, Russia, NK, Iran, etc. are engaging in terrorism, authoritarianism. It's always very black and white because that's how people are educated.

The absolutely overwhelming majority of people are able to go about their lives every day never questioning how they can hold such dissonant opinions in their head simply because they were told "it's ok when we do it, it's bad when they do it".

And as you can see even the "democratic" approach has a chilling effect. The suggestion most people take away from a cursory parsing of the title or article is that Google acted irresponsibly. Imagine the day this point of view becomes prevalent fueled by the typical political campaign populism. Imagine people and companies being put off from touching the topic out of fear that they're branded irresponsible and unwittingly hindering anti-terrorism efforts because they're disclosing problems of general interest.
I also like that the boat is stuck, but not for the same reasons.

A stuck boat in general is not usually a big deal, but this particular stuck boat is giving visibility to how fragile and interconnected everything is. Of course we "know" that, but we often don't see the extent of it until a disaster happens.

A system's capacity got stretched. For a while this worked fine, but safety margins became smaller. It was just a matter of time before an accident like this would happen. And there is no redundancy (on this part of the canal).

So I like this stuck boat because it shows where "the system" has weaknesses. The system extends of course into many areas. Trade, finance, engineering, probably politics, etc.

Unfortunately, due to greed (oops, "efficiency") we will always be running systems at, or slightly beyond capacity so accidents/disasters like this will continue to happen.

I also like that the boat is stuck simply because it is an example of how quickly the world can "unite" in peaceful discussions around an absurd situation.
The mess at Medium: 14 current and former employees explain what went wrong
I didn't know pheasants were released each year for shooting. I assumed there was an established native population.

I've been clay pigeon shooting and it was fun but I was quite disgusted by the amount of waste involved. The shotgun cartridges are not only plastic themselves but eject a piece of plastic wadding out the end of the gun littering the environment. You can get biodegradable wadding but it's not required everywhere and the plastic cartridges are cheaper. Together with the released pheasants this strikes me as quite a big environmental impact.

This. Transition to renewables is not just about replacing power plants, it is about changing demand structure.

Negative prices are an incentive to build power buffers, or to use power when it is plenty. You can even do crazy things like make steel.

One funny side effect that might happen is that for individuals, power will not become more expensive from renewable energy, but rather cheaper - so cheap that the metering it is more expensive than the electricity, so there will be flatrates (up to a certain usage). The reason is that personal usage is just a drop in the ocean compared to all the cars and all the other things that now run on fossil.
I agree that they aren't the most professional thing to use, but I'm not sure why I agree

Maybe it's some kind of bias?
The simplicity of the stuck big boat doesn't matter to some people. The schizos have already done their research and figured out that it's Hillary Clinton's boat, and that it was EMP'd in a show of force to metaphorically represent her imprisonment. And the fact that they don't just take a few tugs and pull it out is because they are doing it on purpose to disrupt world trade enough to justify the "great reset."

There's your look into the insanoverse that some of our compatriots live in.

> When these devices reach their EOL as a phone/tablet, they would make wonderful SBCs with integrated touchscreen

Try postmarketos, it's designed to run vanilla Linux on old devices such as phones.

CPU and USB OTG generally works, which already make for a pretty general-purpose machine. The touchscreen also works most of the time. The rest is generally hit-or-miss, depending on how much time you or the maintainer spends on making it work, or if there has been a mainlining effort.
In my company we have a different "trial period" for promotions and "role-shifting", outside the goals' framework. In my case that doesn't apply then, but I understand your point. You can as well put in place goals for the report in a private way (e.g.: discussions in 121s).
Still, it's worth applauding. Though you're very right that the layman reader will see this as "we're almost there" whereas getting total electricity production to match demand on average is really only the first few percent of the work ahead.

The unexpected value of innovation design for anything you do
This is an outcome of my frustration to explain to people what I do – who is an innovation designer?

But no one would care just about that, of course, so I tried to describe the reasons of why good design principles are useful to anyone who aspires to be a better problem-solver.

I wonder if other designers here would explain it in a different way (how?), and what materials/methods do you think are best for beginners in innovation/product design?

Hey HN,

Thanks @Aissen.
Didn't know whether the project's unfinished state was worthy of it, but happy to see this appear on my favorite minimalistic website : - )

Here is the full video: https://www.youtube.com/watch?v=L1Ui-y8ajJ0&list=UU49EYw900L..., which also provides a bit of the background. And the project website has more of the story + demos.

I'll answer the existing comments, and welcome any new questions, whether deeply technical or completely casual. (After all, the project's goal lies at the intersection of these two!)
Our company does OKRs, which is also basically just measurable goal setting.

I feel like if I was in a decision-making position in the company, OKRs would make more sense. If I have that kind of power and responsibility of deciding what the company is going to do, then I also have to decide what we want to achieve.

But as a software engineer, I don't have any such responsibility. I make what I am told to make. My only goal is to do enough work well enough that the company thinks it is satisfactory. Beyond that I just want to do as little as possible in exchange for the most compensation possible. I also don't have any long term career goals other than to escape capitalism. Therefore when I'm asked to set goals, I find it exceedingly difficult.
My direct boss, yes, absolutely he could do everything I do and perhaps even do it better. His mind is brilliant for being able to see the big picture and know the potential pitfalls. When I spitball ideas at how to solve a problem, he seems 5 steps ahead. With that said, he plays a different role. He is more like the arbiter between business and engineering. And I like him having that role.

With that said, I actually DO NOT want my C-suite to have coding prowess. I prefer them to be gifted in their areas. I love knowing that our CEO is one heck of an inspiring guy but I don't want him meddling in engineering. I'm sure he's smart enough that he could figure it out, but that would be a waste of his talent. Right now, his brilliance is evident in the people he's put into leadership. They're all experts of their domain. This frees him up to do more CEO things (like get our next round of funding)
Sure, but that doesn't mean that any one person is protected from, say, a capricious and arbitrary manager — and it's absolutely legal.

In any case, saying "a company cannot fire you just like that" is patently false in jurisdictions with at-will employment, which is what I was pointing out in the OP's comment.

Can anyone recommend a PDF to HTML converter?
If the app was open source/free in some way, and coops forked some of the money into development, maintenance, infrastructure, etc, then maybe it could really undercut the big guys, have quality, innovate fast and etc and also distribute capital fairly. So instead of having a big guy owning everything and dealing all the cards, the development people would get paid for the service provided to the coops, who in turn provide service for consumers. I've actually had conversations with a friend on doing this exact kind of thing.

25% of lowest demand sounds amazing! I'm mostly a pessimist about renewables due to the storage issue so I would have guessed more like 2-5%.

Assuming lowest demand is at night, that means that building just 3 more batteries you could power the whole state for an hour at night?
