> Considering they have to pump in x-rays, does this even stand a theoretical chance of being net energy positive?

No. The cross section for photodisintegration of a deuteron is much smaller than the cross section for loss to electrons. So even if 100% of the neutrons produced lead to fusion (which I extremely highly doubt) it could not be anywhere close to breakeven.

The only way this might work would be if one could accelerate the deuterons directly and beam them at a deuterated target. But that's been done for 80+ years, so don't suddenly expect those results (that it cannot be close to breakeven either) to change.
Is Scrimba open source?
Not necessarily. Believe it or not, dexamethasone (another corticosteroid) is actually a second-line treatment for this disease because it reduces endogenous cortisol production without binding too tightly to the mineralocorticoid receptor in the kidneys.
> No. The CDC should be given full permissions to do what it needs to do to prevent a public health crisis.

So if the director of the CDC decided that, in order to protect the public health from an epidemic, everyone of, say, Chinese descent in the US needed to be herded into incinerators and burned, that would be okay?
I haven't been arsed to do it yet, but I'm often concurrently connected to separate wireguard subnets with their own dns so the sane thing to do would be to run a local dnsmasq and map it there instead.
It was an oddly contemptuous take IMO. Like what's the beef with having a single frying pan? If you really don't cook anything at all, why do you have even one? Or there's no reason you couldn't cook 3 meals a day in a single frying pan if you wanted to, just a little more cleaning.

As a small-kitchen-haver, cooking is perfectly doable. What's tougher is making enough food for 6 people or a 4-dish meal.

I don't have research to cite about specifically whether novel recommendations get clicked more often. However, YouTube makes $15 billion in revenue. The recommender is responsible for an enormous fraction of that revenue. Google and YouTube have an enormous group of talented ML engineers. I am certain that they have tested changing the proportion of novel recommendations, and whatever proportion they use is the proportion that maximizes engagement.

Personally, I hate the YouTube recommender as well. It's particularly aggravating that I'm stuck with it and its lack of configurability even though I pay YouTube to make the ads go away, so they get no additional revenue when I watch more.

However, Netflix does many of the same things as YouTube, including autoplay, because they have found that autoplay makes you watch more, and if you watch more, you're more likely to renew your subscription.
I've built that. This works on small, well synchronized teams, on small databases. Once you have to merge a branch, you start fighting over version ids or renumbering like it's BASIC. And remember that any long-lived dev session is effectively a branch. Heaven forbid you have environmental conditionals to apply.
I think it’s the opposite. Any idiot raccoon can raid a trash can and get lots of calories. And unlike rats we are generally not out there looking to kill them.

Wow, that's a very racist/sexist statement and you don't even leave a hint about why you think it's true. Worse, it reads like you expect it to be obvious. What about a person's gender or skin makes them "a bad demographic for social networking"?

Edit: Also presumptuous of you about the HN crowd. Where would you even get those statistics? HN doesn't collect that data.

The parent poster was asking about "well, isn't it an issue with your TSL definition of 'DDL schema access' if you can store data in JSON or EAV so it doesn't have a 'fixed schema'", and my answer is: No, that's fine.

Just like it would be fine for you to store or use binary/blobs/arrays/whatever. We've seen some crazy/cool use cases like developers storing binary 3D lidar data in TimescaleDB.

In fact, with these "right-to-improve" changes, you could even modify the database to embed custom logic inside TimescaleDB to handle your protobuf format (as opposed to UDFs or application code), and it would still be permitted.
I don't care that they made money, but I also don't trust Kendall to spin the topic if it suits their interests. Why would anyone trust the manufacturer of anti-facebook software about the dangers of facebook.

In this case, it doesn't much matter because they didn't say anything new or of substance. Facebook is designed to be "addictive". Any psychology undergrad could tell you this.

I have to admit, when I find a good sale, I have a hard time only buying what I need instead of 10X what I need since it's such a good deal (I have at least a 20 years supply of jeans unless I get fat).
The headline of the article, as is often the case, overstates what the actual research shows. Here is the actual claim made in the abstract of the paper:

"We show that single-neuron responses in the pallial endbrain of crows performing a visual detection task correlate with the birds’ perception about stimulus presence or absence and argue that this is an empirical marker of avian consciousness."

In other words: when crows who are trained to look for something show behavioral evidence that they see what they are looking for, the researchers can correlate that with neuron firings in their brains. Which, compared to the overblown claim of "higher intelligence", equates to "whoop de freaking do".
> We have a court system to decide if these decisions fall into the public health crisis prevention.

Wait, is that the argument that the CDC should be given full authority to decide what needs to be done to protect against the disease, or that the courts should supervise not just on whether the action is authorized, but also effective at the stated goal?
I do not read that the previous poster meant that the superior one was morally superior. Only superior in terms of violent power.

I think the origin of "Staff, Senior Staff, Principal" came from an attempt to create an IC track. You've been around a while, and you can execute stuff well on your own, where does your career go from there besides manager?

The fact that the assumption was manager is why we have a lot of these problems, tbh. I hate managers who hate managing but that's a separate discussion.

Also funnily enough I was just having a discussion how my company's career ladder explicitly says (in bold!) that promotion is not a reward. If it's not, what is it? What is the reward for hard work and growth, if it isn't that?

Ultimately what I see underlying this article and many like it is an assumption that, at least at an "enlightened" company, politics don't matter. If a company prioritizes low-impact high visibility, that's a stupid company... Yet I've never seen a company free of politics. There will never be a company where your personal assessment of impact of your work matters more than your boss's or their boss's.

We also can't pretend like the amount of work at any given level matches the number of engineers at that level (or who want to be at that level). It just never will. So there will be jockeying for position.

You shouldn't be playing politics all day (a trap I sometimes fall in) but you can't ignore it either. Politics often means justifying your work up the chain, being aware of priorities of those above you etc - it's not just kissing up. Ignore it at your peril.

Yes, the reason we have laws against face punching people who say dumb things is partly to protect free speech in the philosophical sense (there are obviously other reasons too, such as that it hurts).

This still doesn’t mean that speech without consequences is possible. The grandparent comment mentioned the loss of a livelihood as an example (unsure exactly what it refers to but could be e.g boycotts).
On the contrary, Google made Kubernetes precisely so they could commoditize every other cloud provider and then offer the strongest Kubernetes provider there is. When AWS is just a layer under Kubernetes, you can move your entire infrastructure to GCP by pushing your Kubernetes config to a different endpoint.

They succeeded quite well in that.
> If I am a bad actor I can submit an app for review and activate an evil mode after the application is approved.

While this is of course still possible, the store model allows you to disable the app and remove the store listing to prevent further distribution of the bad app. You would be giving this up ability if you allowed third-party distribution. The fact that review is necessary in the first place also serves as a deterrent, and if a bad actor is caught their developer account can be banned to prevent them from submitting any more apps.

> Maybe we can stop pretending that the lock is in place to protect the users

Not sure why you think this is a pretense. In 2019, Android devices were responsible for 47.15% of malware infections compared to 0.85% of iPhones (https://onestore.nokia.com/asset/205835). There is a clear security benefit to the locked-down store model.
You can copy business models but you can't copy trajectories. Their failure is not selling businesses fast enough. Perhaps they drank their own Koo-Aid and thought they could build an actual tech behemoth out of copying ideas but clearly all the things they copy have the same uncertainty that the original ideas they copy have.

Maybe they thought that they could pass that upper limit of uncertainty with capital and operational speed but that doesn't work for unproven ideas. It's not like a private equity buying a crackers company. Startups in general have very undefined horizons with no operational references or data to build on. How could something like FoodPanda be successful when all the other players in this space struggle and just a few are barely successful?

It does seem like an opportunity for startups to catch some amazing talent by being more open-minded in these types of interviews. Generally startups have a much smaller interview committee, sometimes even just 1-2 persons, so they can control better for not having these silly criteria.

I want to first help students connect with others university-wide. That way, a group of students can discover and connect with each other who otherwise might not because they don't share the same academic goals. Also, Alto is a synchronous platform so it's important that students, immediately after they sign in, can begin video chatting with someone. That's more likely to happen when it's open to the entire student population.

I plan on launching groups in the future, subject to change based on feedback, where any cohort, student org or course can have their own group. At this point, it'll be easier for any student to discover other students based on mutual personal/professional/academic interests and frictionless since everyone will already be on the platform.

What's the demographic of your cohort? Is it based on major, year or some other factor(s)? Is the Discord server you're talking about university-wide or cohort-wide?

I've only used Discord a few times so I'm unfamiliar with its features, but I think Alto has less friction when compared. Alto prioritizes video communication, makes it easy to discover any classmate in your school, and in the future, any classmate associated with any group all in the same place. Additionally, Alto allows you to directly invite another student to a video chat room and know within a few seconds whether or not that person wants to chat without messaging back and forth.

I may be completely wrong about Discord's existing capabilities so you'll have to correct me. Also, I would love to learn more about your experiences attending university remotely and using Discord. Let me know if you're free to chat!
Well it's a direct market, customer service is king.

The sellers cannot really move their 'brand' from one market to another. An opportunist could reserve their username on another market, and users know that anyone could be behind that new account. They don't trust the name, only the reviews you have on your particular market.

What I want to say is that the reputation of their anonymous brand is worth something, because they can't take it somewhere in a hurry and takes time to build (if you build it legitimately, it always seems easy to cheat with a bot).

Reviews from other users, (who also have a visible reputation, to combat botting), are taken seriously. The markets themselves provide escrow, if you screw your users and don't have a high standing you're likely won't be receiving payment.

This incentivizes sellers to provide a high level of customer service.

> Rents are not interstate commerce - they're local.

Existing Commerce Clause jurisprudence gives the feds authority to act to control things which indirectly touch on interstate commerce, which pretty expressly includes the interstate movement of humans and the impacts therefrom.

Its not a big stretch to get acting to control communicable disease from that. It is well-established that if it is acting to manage something it is authorized to manage, the feds don't separately need independent positive authority for the mechanism (in this case, the eviction moratorium), just the absence of a negative regulation. So, I don't think (other than the risk of current courts seeing the Commerce Clause more narrowly than existing precedent, a real risk given the rightward movement of the courts) the Commerce Clause is insufficient for federal authority.

I do think that the nondelegation doctrine may be a problem for the broad interpretation of the statute necessary to read it as putting this federal legislative authority in the hands of the CDC through the existing statute (whether that would mean the statute itself is read more narrowly or facially invalid is another question.)
Really?

Microsoft, Amazon, Google, and Apple already have my CC number. If I could buy all my apps through (ex:) the Microsoft store that exists on PC, Android, and iOS I could delete my CC info from Google and Apple. That's a win in my book.

Maybe the competition would force all of them to innovate a bit. Wouldn't it be nice if you could give your CC number, but set a hard limit on in-app purchases? Ex: Here's my CC, but you're not allowed to charge more than $50 / month to it. I bet there are a lot of people that have gotten multi thousand dollar IAP bills that wouldn't mind a better system for some of that stuff.

I'm in the process of writing up my thesis, focused exactly on this domain; collars for detection of eating, rumination, and oestrus behaviour (welfare and fertility), from Afimilk Silent Herdsman (collar system was originally a spinout from my University), combined with Automatic Milking Systems (robots) from Fullwood Packo (the Merlin).

In general, the cows are more driven to the robotic milkers by the feed they recieve while in the machine, rather than the feeling of relief (these systems generally provide an alert of cows being lazy...ones that haven't been milked in 10+ hours and need a shove), however these systems _do_ provide both improved health and improved productivity.

Even in experienced dairy herds, handling the animals and shoving them all to the robot at the same time causes stress. Having these machines running constantly (1 machine can handle a herd of ~50) lets cows regulate their own pattern, which can benefit herd dynamics as well (more timid animals can self regulate to a quieter period away from pushier animals). Farms can easily see 10-20% improvement on milk yield.

It also has the benefit that animals can go more or less often...you may have some animals who are comfortable with 3 visits a day, some comfortable at 4 (or even 5 if they have really high yield).
I wonder how this one will go. I wish I lived closer to most of these companies data centers. It'd be great living in Spookville, Virginia right about now if you were into these game streaming services.
this is interesting. theoretically, more liquidity should lead to more efficiency in the distribution of a commodity . in practice, there are obvious exceptions to this (the hunt brothers & silver, the oil markets from 2006-2010 etc).

I also wonder how a futures contract with instant liquidity interplays with standard water bills, which as far as I know are billed at rates that get adjusted yearly at most (at least here in LA).
I wonder could you breed crows like you do dogs or livestock by selecting for the largest brain in each generation? At least physiological changes seem to be pretty profound but maybe the brain is harder to coax to grow.
