As appealing as that narrative is (just utilize waste electricity, its cheap/free!) a plant (making anything, not just this chemistry) that only runs 50% of the time for e.g. nighttime electricity costs twice as much[0] as one that runs all the time.

To the parent re: efficiency and economics, the supplemental info: https://pubs.acs.org/doi/10.1021/jacs.9b07310 (as a rule, free/open access w/ 90% of the utility of a given paper) has the half cell potential at about 0.6V[1] vs RHE, which puts a whole cell potential at about 2V. So count the electrons to convert CO2 to propanol, take Coulomb's constant to get amps, convert to watts, and do the stoichiometry to get kwh/tonne propanol.

This is all ignoring throughput and CAPEX utilization, which is almost certainly poor (but not unexpected at this stage of research).

It is also worth noting that they are using a 3 dimensional, convoluted electrode (carbon cloth) to support their catalyst which may be responsible for the claimed 'trapping of CO'-effect, rather than their specific catalyst. Notably C3's have been observed before in CO2 reduction from less involved catalysts.

tl;dr Probably not very efficient at all, I'm too lazy to do the math. If it was efficient, it would probably still be wildly uneconomic to make propanol via this route.

[0]per unit of production, revenue

[1]Don't forget to account for side product production, per the supplemental information they are making about 600 moles of H2 per mole of propanol (hard to read the chart).

I know a lot of people who did like the "smart" features, in that they could stream online content of one kind or another direct to their TV.

I think the change we're starting to see among my group now is that the built-in software is starting to get out of date and not necessarily being maintained by the provider(s) of the service(s) affected, meaning from the user's point of view, the TV just turns on one day and can't connect to service X any more, with no way to fix it.

I'm not sure privacy has much to do with the discontent, because as you suggest, I doubt many people are even aware of the kind of tracking that is going on. When "smart" TVs or related devices get updated firmware and start doing things like injecting ads it really upsets people, but until they have some indication that any of this is happening, of course it doesn't really affect them or their opinions.
Could these legal arguments be extended to lookalike audiences that are built off of email lists that have a gender imbalance? That is, imagine I go to a university to recruit, and I talk with 200 male students and 10 female students. I then take their email addresses and make a lookalike audience to advertise my jobs to. Could that be challenged on the grounds that I am trying to advertise to male students? What if I don't know what goes into the algorithm of creating lookalike audiences — for example, how important gender is versus interests.

Well, I mean, if you'd rather a political than a mechanics-of-law explanation as to why the law treats two situations differently mo, it's legal because heterosexual couples plus women outside of such couples combine to form a powerful voting bloc, and gender rating, compared to it's absence with no other change in practice, is a benefit to that group.

Specifically, compared to perfect allocation of costs, it's a small subsidy from people outside of opposite-sex couples to opposite-sex couples, whereas not having gender rating with otherwise status quo policies is a large subsidy from women not in opposite-sex couples to men not in opposite-sex couples.

Under status quo policies, opposite sex couples are in practice fairly free to gender-optimize insurance pricing by putting the less expensive to insure driver as primary on the more expensive to insure vehicle, regardless of actual primary driver.

An arc on AC is more likely to be extinguished since the current drops to zero many times every second (so eg, on 50 Hz AC, an arc is not likely to last more than 1/100 of a second). DC switches and circuit breakers are designed with greater concern for arcs.
> And without an iota of malice in anyone's heart, relevant actors can reproduce the same exact disparities that perpetuate inequality. This is called systemic discrimination.

That’s not systematic discrimination. It’s express discrimination and illegal.

Systemic discrimination results from policies that are facially sex or race neutral, but have a discriminatory impact because of structural discrimination in society. (E.g. not hiring people for having marijuana convictions may be an instance of systemic discrimination if black people are convicted far more often for possession despite using drugs at similar rates to white people.)

There's another related point here too: women and other people who form smaller groups in some context talk to each other. Have openly shitty approach to them - it will be known. Treat them with respect - you'll get recommendations in that employee market.

Why not PV on the ground: because wire antenna is a lot cheaper.

Why people don't have to trust us: because the technology isn't physically capable of maintaining even that low energy density at the target, without the reference signal from the ground.

Why put the PV in space instead of on the ground: because there's 5.4X as much energy available and it's 24/7.

I haven't read the book, but the viewpoints he expresses in the interview are spot-on. DL can a great alert/suggestion mechanism in narrow domains, but it should never be trusted to make critical decisions. I believe that general intelligence will only be achieved through major advancements in general symbolic reasoning. Something like DL might play a small role in this breakthrough, but it will not be a core part of the solution.
Doctors want you in and out of the room in 5 minutes or less so they can pull the insurance money dispensing lever again.

The last physician I had any respect for was my own pediatrician and I had consulted him on various issues having gone through several GPs that got even simple diagnoses disastrously, hilariously wrong. Such as telling me the tiny red lump in my finger was an anthrax infection and notifying the health department when it was really a small benign vascularity that was removed in a fifteen minute procedure.

Since my pediatrician retired I just do all my own medical research and order my own lab tests. The advantage I have is that I have all the insight into my own body, history, and habits that no doctor these days ever takes the time to find out. You're just a money pinata.

The argument from the article is that in non-Apple ecosystem, the ongoing fee is 0, which is smaller than all 3 of your listed examples. Also, as opposed to "simple command-line build scripts", in non-Apple ecosystem, there is no script required to release versions. I don't see the argument weakened, but rather strengthened.

You know what? Reading your post has now made me want to convert another machine, that I have sitting right here, to use Xubuntu because Ubuntu does seem to have much more official support for things, plus I'd really like to compare it to Manjaro and finally many of our servers are running Ubuntu so it will be nice to get a deeper familiarity with it.

I was just this minute looking at .NET Core 3.0 as well because I had such a good experience with 2.2 on a recent job. Your comment actually alerted me to the fact that I can't get it yet :)

I was off of .NET for years doing mainly Node.js/Angular/React and I'm kind of excited to be getting back into .NET - I'm so glad my 15 years of .NET experience won't go to waste because ASP.NET has been looking very good in web server benchmarks. Plus, C# and .NET are much nicer to work with than JS/TS and Node IMO. Everything is just cleaner.

Anyway - good luck and I hope you have a lot of fun on your Linux desktop adventure. One of my favorite things about the switch over the past year has been the fun of being a sort of hobbyist again, exploring and figuring things out. At this point, I have setup 4 different desktops and I even got advanced touch gestures working on my cheap Acer E5-575g laptop. Can't wait to setup Xubuntu next! So, thanks to you as well!

The ad must have discriminatory intent [1]. So if you're selecting candidates with a black box ML model and you didn't explicitly include racial/gender preferences...

But "the algorithm was sexist, not me" is probably going to be a losing argument in any court case.

If you wanted to command, let's say $5-8 megabucks per year conservatively, I would sell the idea of self-programming systems. Automating software development to not need as many humans and implement prototype systems more rapidly is a business holy grail because it could significantly reduce the need for as many developers and their relatively large salaries. It will happen eventually, it's just a matter of time and who's going to profit that's the question. Furthermore, as automation intensifies over time, there will be overall fewer jobs but their salaries will continue to increase if they are related to automation and further reduction of jobs. If I were an AI researcher, I would be in self-programming systems, insist on patent assignment and consider forming a startup to deliver it as a hybrid cloud/on-prem SaaS... this would be the most obvious path to get rich from it.

Our project is using something like that - it started nice and simple, but got lots of ugly hacks now. We have some values which use two different sub-delimiters, multiple “mini-formats”, values which contain the name of other keys, magic atrings to represent “null”, and so on.

We got used to this, but results are pretty ugly. We get people confused about delimiter order, broken copy-paste, and so on. For the next project, I’d recommend something which can support complex structures. A schema validation would be nice, too.

It dodges the legal issue if you're very careful with your paper trail and get a sympathetic jury.

You won't get a sympathetic jury. People don't have a lot of empathy for algorithms. Maybe empathy for the people who write them, and then only maybe. But you'll be up against a huge slate of expert witnesses explaining how we already have lots of open sourced methods for teasing out these sorts of indirect indicators.
I think those are two separate issues.

The former is about operational readiness. If your army is unable to shoot at the enemy for whatever reason, you don't have a functional army. Wars are lost because of this (which leads to political concessions and loss of resources/influence/etc), and it's an important topic to consider when your goal is to maintain a standing army like the US.

The latter is, well, morality.

Of course, these two topics clash. How far do you go to ensure an obedient and effective army, while allowing leeway to refuse orders that are immoral?

How will you avoid-

> John Gabriel's Greater Internet Fuckwad Theory was proposed in the Penny Arcade (web comic) on March 19, 2004 by Mike Krahulik and Jerry Holkins. It says that when a normal person is allowed anonymity and an audience, they lose social inhibitions and act inappropriately.

If anything, the last decade has taught us the immutability of this law. Usernames and comment history seem to help somewhat with people acting accountable for their actions. Total anonymity seems to always lead to a cesspool like 4chan.
If we examine Fair Credit and Reporting Act (FCRA), we see that it is not ok to discriminate against protected groups like race even if that means you're taking on more financial risk. Let's assume the data indicates that certain minorities are much more likely to default on a loan. You still cannot use their race to deny them a loan.

The reason is that it would perpetuate inequality. Given that minorities were systemically discriminated against previously by red lining by the federal government and could not get a federally backed mortgage in for decades (which resulted in Urban ghettos, white flight, etc). And given that those injustices have not been properly corrected, discriminating based upon race must be forbidden in the credit markets.

But you can discriminate using other variables. For example, you can discriminate based on education, income, credit history, credit score, etc. And some of those variables might correlate heavily with race.

In that scenario, you can use FCRA compliant variables even if they correlate with race as those variables are (a) cleared by the government, (b) derived from actual facts about the individual (as opposed to predictions). Otherwise, if you in your underwriting machine learning model accidentally find a proxy variable for race that isn't an FCRA compliant variable, your compliance department will require you to not use that proxy variable in your underwriting model.

Your argument "I'm taking on an extra financial burden" doesn't excuse you from ensuring fair access to credit. That's akin to saying "the cost of being handicap accessible is unfair to my business as it costs us money so I don't want to do it". We have made certain rules to ensure people have a fair shot in life and those inherently cause an increased cost to businesses.

Now, there is actually more nuance to this. For example, if you provide a credit product but you only make that product available in certain zipcodes, you could actually run afoul of fair credit laws if the zipcodes you include versus exclude are heavily correlated with race. However, if you are a very small business and don't have the resources to provide your services in all markets / zipcodes, then you likely would be ok simply because having to provide your services in the many places might be an undue burden on the business. However, as you grow and become more financially stable, you would/night need to fix that.

I certainly don't blame the developer for not supporting macOS, but the reasoning he outlines in his post aren't particularly compelling to me. It seems to me porting his game over to MacOS in itself would be a larger undertaking and more valid complaint than the ones he's listed.

The notarization process potentially reducing the number of builds he can push to users in a day from 6 to something less seems like a feature, not a negative.

That's direct discrimination, and I don't see how “the current form of identity politics” supposedly creates an “out” for it. Please elaborate.

We have excess power in many places almost every day with wind and solar. Often the utilities get charged whether they use it or not. Sometimes they even get charged on top of their regular rate for not using it. The more solutions that use this surplus power, the more the utility can cost-effectively integrate renewables into the grid.
