> But without making it clear to anyone else in the volunteer community that that's what you've done.

You mean like pretty much 100% of everything else going on in a typical open source community?

I’d wager at least 99.99% of the users don’t even knows who or how many maintains a piece of software, nor if updates are based on external patches or (core) internal development.

They just sit there entitled and expect free (gratis) software which works for them without providing anything in return.

I’m not saying that because I’m a bitter maintainer, but it’s just a fact of life.

You couldn't inform these users about any changes at all even if you wanted to, because they’re simply not involved and they never will be.

Anyway, if they cared, if they were somewhat involved, they would know. As it stands, it’s their own fault for blindly trusting random code from the internet.

And really: mostly changing maintainer for a new, more motivated one usually works out better, even for these users, so why should the burnt out previous maintainer feel bad about this?
This is a suspended style, unlike the Japanese maglev- it's much more like the old transrapid[1] which used a set of coils underneath the track to pull up the train. There are pros and cons to both.

The Japanese maglev uses large unpowered copper coils in the sidewalls[img:2]. They're arranged and interconnected in such a way that they keep the train up and centered. They're quite expensive to build, but more energy efficient.

The suspension style can use smaller coils but they need their own power, which is lossy and can limit the length of the track. In both cases the train typically needs its own generator to create all the power.

The article says that the plan is to make the cars very light, which is plausible- train cars are way heavier than needed; they weigh several times more (~1000 lbs/person) than the people and luggage they can fit. The strength is important though, as the car needs to pull the rest of the train as well. It may limit the number of passengers per train.

They'd have to build entirely new rail for the entire line from Beijing to Shanghai. That would be a very large investment, many times more expensive than just rail. China is preparing for a never-before-seen level of infrastructure and doing anything they can to avoid cars, which would be an ecological and logistical disaster for them.

Maglevs are kind of questionable. The use case comes from moving between large cities- plausible in America, but China already has some of the largest airports in the world and less of a middle class to use them.

I don't have access to a proper data acquisition system that can sample at kHz rates and I'm not willing to buy one out of pocket.

SCADA systems and HMIs are generally not set up to poll data from PLCs faster than 1 Hz.

Using a driver for the PLC communications protocol I write all of the variables of interest to a CSV file at 10 Hz.

PLC scan times are usually 10-100Hz so while I can't capture everything the PLC sees or higher frequency components to the signals than the PLC can measure, it is happy middle ground between a proper DAQ and just using the HMI software.

In addition a DAQ wouldn't be connected to all of the PLC IO but with this system I can easily grab all the PLC tags I want, as well as internal PLC tags that are not IO points.

Most HMI software has pretty brutal plotting capabilities as well (Citect process analyst being the only one that is better than passable), so on top of getting at least 10x the resolution in the data I get to use KST which is great for zooming and panning on the plots, creating sets of plots, or different plots for specific tests.

Not all HMI software even allows plot configurations to be saved, so you can spend a lot of time just re-adding the time series to the plot and setting the scales.

The plots are used for commissioning reports and records.

Seems like a pretty easy settlement. Hope she gets a lot for this.
Please don't normalise the use of the term "SJW". It's use as a pejorative has far-right origins that attempts to shame social progressivism. Those accused of being one should be proud of promoting feminism, civil rights, and multiculturalism. It is not a bad thing.
I'm basically incredulous to the point where I simply don't believe this is true.

If this was an exercise in 'how to start false rumours to ruin someone' - then it's not just 'questionable', it's shocking.

I can see this as part of an exercise to demonstrate how these things are 'powerful' - but as a training exercise .... it's so abrupt I just don't believe it.

If this is part of the curriculum it should be posted somewhere, no?

Edit:

Here is a paper from Paris School of Economics [1] a 'Grande Ecole' where profs have basically studied how information flows through social networks.

I can easily see a professor teaching this course asking students to 'start some kind of rumouor' to see how the information propagates through social networks.

I don't for a second believe that this would be taught in a manner such that students are being 'instructed on how to use rumours to advance their careers' or some kind of nefarious thing.

I believe it's totally misrepresentative to indicate that schools would be doing such nefarious things, and I think that for whatever reason the OP has possibly misunderstood the nature of this kind of activity.

A quick glance at the paper reveals that this is just regular, kind of interesting social science.

Get a lawyer and get an accountant. Don't do your own taxes. Don't try to file paperwork for business things if you're not 100% confident that you'll do it completely correctly. The $300 you spend on a lawyer to file something will save you thousands in the long run.
I think what parent is trying to say is that there's a present (with different choices in the past) where Hacking Team et al. are illegal, and governments and corporations instead pay out mandated bounties for responsibly disclosed cybersecurity research.

I'd prefer that present. But it's certainly not the one we're living in.

And the NSA, Russian APT 28/29, Chinese APT 1 have responsibility. Not just for their own actions, but for creating a world in which similar actions by anyone are normal.

Matching pills with pictures/dimensions/etc. in pill reports isn't meaningful at all without the results of the reagent kit. If the reagent kit results line up with the pill report results it provides SWIM with an idea of the strength of the active ingredients. It's a sad joke that in 2019 intelligent adults in America can't just walk into any pharmacy and buy a box of 100mg cross scored MDMA tablets with expiration dates.

Again, IANAL, but what I’m reading does not seem relevant to libel. Namely, the pejorative title of the website has nothing to do with the claims they’re making.

If the doc had a libel case, why the hell did they not go for that, instead?
No kidding, JS off by default and not running code you don't trust will always be a good idea. I also agree that I'm not really concerned about exploits that require running code on my machine; if the latter happens, I have far more serious things to worry about.

The exploits that do worry me, are ones that can be done remotely without any action from the user. Heartbleed is a good recent example. Fortunately those tend to be rare.

Security is always relative to a threat model, and not everyone wants perfect (if that can even be possible) security either, contrary to what a lot of the "security vultures" tend to believe.
I think "a pale copy of the real thing is orthogonal. The "real world" is perfectly capable of creating pale copies with many communities as the pressure leads to shallow pleasantries, pressure to conform for the sake of conformity when nobody really likes the status quo but does so because it is expected, keeping up with the Joneses and more instead of what people are actually interested in and value.

Of course it is a matter of how you use it - with both smartphones and "real world".

> As I passed them, I noticed another racial reality. It wasn’t only Brandon and the other young men in the cellblock who were black. So was everybody in the courtroom—not just the judge, but the court reporter, the bailiff, and the juvenile prosecutor. So was the police officer who had arrested Brandon, not to mention the police chief and the mayor. Even the building we were in—the H. Carl Moultrie I Courthouse, named after the city’s first black chief judge—was a reminder of the African American influence on D.C.’s legal system.

> This wasn’t my first time in an all-black D.C. courtroom, but something—probably my anger at the Martin Luther King speech—made the reality stand out that day. When I got back to my office, I continued the racial tally. I had been to the detention facility that would be Brandon’s new home more times than I wanted to count, and I knew that all the guards there were black, too. The city council that wrote the gun and drug laws Brandon had been convicted of violating was majority African American and had been so for more than twenty-five years. In cases that went to trial, the juries were often majority black. Even some of the federal officials involved in D.C.’s criminal justice system were African American, including Eric Holder, then the city’s chief prosecutor.

> In September 2014, the Sentencing Project issued a report comparing the attitudes of whites and blacks regarding crime and criminal justice policy. It found that when Americans were asked, “Do you think the courts in this area deal too harshly or not harshly enough with criminals?” more whites (73 percent) than blacks (64 percent) said “not harshly enough.” Media coverage of the report emphasized what the Sentencing Project called “the racial gap in punitiveness.” But the fact that almost two-thirds of blacks displayed such punitive attitudes received little notice. How could it be that even after forty years of tough-on-crime tactics, with their attendant toll on black America, 64 percent of African Americans still thought the courts were not harsh enough?

One of the ways we “otherize” African Americans is by denying that, just like white people, they want secure neighborhoods. And because they disproportionately live in poor neighborhoods, they are disproportionately affected by crime.
> Our spreadsheets hammered home that what contributed most to our happiness was time spent together or with friends — while, crucially, not working — and there was no way to get more of that if we continued to live in the Bay Area, one of the most expensive parts of the country. So I proposed an idea that would have seemed radical were there not so much data backing it: “I think you should quit your job, we should sell our house, and we should move somewhere cheaper,” I told my husband matter-of-factly one day. So we did.

I do like that the impact is in "equivalent CO2 tons" allowing comparison across more than emissions. Yes, scaling by cost is questionable but allows simple policy comparisons.

Good luck finding any analog gear period that can saturate 24 bits and not have noise in the LSBs, it just doesn't exist. That's not the point of 24-bit audio, it's not needing to worry about clipping. That's why knocking it down to 16-bit for playback is practically speaking fine.
The average life of a car is only 10 years? Wow. I tend to use my vehicles much longer than that and I don't spend a lot on repairs.

Maybe this average is a result of accidents after a certain age. Almost any accident in a 15 year old car will cost more than the vehicle to fix professionally. I was surprised by the number though (which, to be fair, they didn't actually list).
The MNT Reform[1] is an interesting option, although it's not available quite yet. One thing in particular your post made me think of is the fact that they've changed the battery to a bunch of 18650s that you can swap out at your leisure. Also, it's all completely open with schematic and source code online, and they mention that if they make a RISC-V board, it'll fit in this one's chassis.

I have not found the cultural climate on HN to be opposed to the GDPR at all. Both its goals and its implementation seem to be popular here overall, and most comments I see that are critical of it get enough downvotes to have their text significantly desaturated even if they're making a good argument.

It's my impression, though I have not worked in the field that people operating ad networks believe some kind of tracking is necessary to prevent click fraud, and do not want to sell ads free of any tracking even when they have customers asking for the option. I don't know how true this claim is or whether alternatives have been adequately explored.

What I do know is that some of the industries that use ads, such as newspapers are struggling to make enough money to continue operating. Nobody will miss a scummy adtech firm, but people might miss local news outlets. It's valid to talk about the impact on business not just in terms of profits, but also considering potential positive externalities of the continued operation of a given business.
With at-will employment, Chipotle can fire her for no reason at all.

> This means that employers may terminate employees for any reason or for no reason at all, as long as it is not illegal. [1]

Wrongful termination would only apply if Chipotle fired her for being a member of a protected class, or as retaliation for asserted their legal rights.

Neither of which applies here.

> it’s petty theft, car break-ins and such. Nothing to worry about

Why are people so chilled-out and blasé about having their things taken or damaged? Are you genuinely not bothered about the destruction due to a political belief about property or do you think it's unavoidable? It doesn't happen in most places - it doesn't have to be that way.
To say that this article is misleading is not enough. This article appears to be deliberately deceptive. Nissan Leafs are specifically known to have battery problems such that they lose a large percentage of their storage after a few years. The reason the batteries need to be recycled for other uses is because they keep having to be replaced, and they need to do something with the old batteries that are no longer useful for cars. Sure the battery might outlive the car, doing something else. Meanwhile, the car will need several battery replacements.

Exactly, fully agree. It's a DSL of this era.
Just follow the rules that Benjamin Graham set out and invest for the long term and don't speculate - which is what a lot on here think investing is.
Is everyone who doesn’t agree with “social progressivism” considered far right now? What you’re doing is language policing, which is one of the reasons many find SJWs offensive.

You could lose a car on the back for departing passengers and pick one up on the front for embarking one’s. Only a bit of loss in kinetic energy needed (to slow down the last car and get the first car up to speed).
This seems like a pretty even-handed analysis of the consequences of GDPR. I correctly predicted most of them, and have been highly criticized for it.

It’s truly stunning to me that a community like HN that consists of many current and future startup executives can be so adoring of regulation that has “been the death knell for small and medium-sized businesses“ and for which “compliance costs are astronomical” according to the article. I sense that it is mostly the vocal minority making these comments that ignore the seriously negative consequences of GDPR and paint any company or person that is critical of it as a privacy abuser. I suspect that it is the same small group of abusive users that downvote any comment critical of GDPR into oblivion. Still, it is a very bad look for a community that claims to be so invested in startup culture.

It really is OK to recognize that something with good intent (privacy legislation) can be poorly written and consequently fraught with problems (like GDPR). Any idiot could have predicted that the fine structure they imposed meant potential death for small businesses and a mere speed bump for large ones. GDPR should be torn up and rewritten. The fine structure should be a percentage of revenue, period - not 4% of revenue or €20 million, whichever is higher. That is ludicrous and was designed specifically to drive small businesses out of the market.
> Pretty cool business model where putting dangerous vulns in your product can help you capture 90% of the market.

This is extremely disingenuous phrasing. You seem to be trying to craft a narrative that makes putting security vulnerabilities in products an intentional thing to sabotage people, time, and resources.
But actually those that use "SJW" in this way are not in the main stream - so yes they are considered far right.
I’d have kept my Leaf if I could have upgraded the battery pack when it came time to replace it.
Journos did the same to Nick Sandmann and IIRC CNN's people were in on it. It's not just random tweeters, the priests of facts and truth are no better.
It is generally adversarial to call people labels they wouldn't use themselves. Sometimes that adversarial tone is warranted. On Hacker News, in a top level comment that's starting off the conversation is probably not one of those places.
I think few people would disagree with you. But this is really the biggest danger. If you look at the studies that have been let's kindly say 'found to be less than well supported', you'd also find many that you would intuitively agree with the outcome of, or at least want to agree with. Psychology, and social psychology in particular, has a habit of confirming our biases and making us feel good. This, in turn, takes us off our guard for bad science. And by "us", I think this is something that's likely even issue within the field itself. You don't get a 23% replication rate without there being some very severe problems within a field.

Take for contrast, astrology. We all now know it's obviously fake. It even relies upon things we know are wrong, such as assuming planets can magically stop and start going the other way in their orbital trajectory. That assumption was based on an optical illusion driven by the assumption that everything revolved around the Earth. But for hundreds of years astrology was treated as respectable a science as any other. And I think it was for a similar reason. So compelling and entertaining are the correlations for astrology that even today you have millions, if not billions, of people that still partake in it to varying degrees.

The psychology replication crisis is, in my opinion, hurting science as a whole. We should not indulge bad science even if it happens to tell us what we want to hear. It's making a mockery of what science is truly about.
Yes, current nuclear technology will not play a big part in preventing climate change because:

It’s not infinitely powerful: It only contributes 5% to the world’s energy supply[159] and even in China, where regulation is lax and public opposition to nuclear is not as big an issue for policy-makers, few reactors are currently being built (_six_ in the last 18 months).

It carries safety risks.[160] While advanced nuclear power in some advanced economies might actually reduce nuclear proliferation risk by using up nuclear material, in other countries, nuclear power might increase proliferation risks.[161]

It will not be used in many emerging economies.[162] Consider that only 1–5 countries in Sub-Saharan Africa are currently plan to have commercial nuclear power and these countries are at least 10 years away from starting construction on nuclear plants.[163]

Continued reliance on outdated nuclear technology might not have the same crucial global technology spillovers as investments in other clean energy (including advanced nuclear). Since the best path towards global decarbonization is through global technology spillover into emerging economies, the actors that have the best emissions score may, surprisingly, not be the most effective actors at reducing the global rate of emissions in the future.

We need more energy R&D to make nuclear better new small modular nuclear reactor designs.

It depends a lot on where you live. Cold climates with salt and ice destroy cars. Loads of rain can do it too. Where I live in SoCal cars last absolutely forever. You see people driving early 90s Hondas all the time and they've just gradually fixed stuff. The body is worn but basically good after almost 30 years. I imagine here a Leaf could outlast its batteries, but maybe not in Michigan or New York.

The battery is the most costly part of an EV but battery prices are falling rapidly. The rest of an EV is simpler and has fewer moving parts than a gas car and will probably last longer.
