I think the biggest difference is most games tend to have anything not dead + positive resource stream = a win. People tend to build city's / county's / etc that go through a major such phase to maximize resource collection.

In reality you generally don't want to have 40 years of suck to get to some long term gain, because you need to live those 40 years.
Really cool! It looks like they have some overshoot on their servos. I think adding some damping to their control loop to get closer to critical damping would shave a few percent off their time.

This is awesome. I love that this is what they did to solve this problem, versus something overly technical, like tuning the cameras or post-processing the images.

Is this article appropriate for hacker news? Keeping in mind that to be on topic means: anything that gratifies one's intellectual curiosity. I know that the guideline is generic, but I am seeing more and more articles that encourage emotional distress rather than entice intellectual curiosity.
I don't even mentally error check placenames in the UK - someone could tell me Wibly-upon-Fluberstuck was a place and I'd probably believe it.
Speaking as someone who has definitely had lazy tendencies in the past and did very well before college while doing almost nothing, this does feel very fitting to my personal history.

Although I would argue that the failure is one of the educational system - not that I try to avoid taking responsibility, but children in this context are the innocent participants in a system set up for them by adults. Innocent as in that they don't know any better until they're older.

The problem is one of understimulation. I do actually like to work hard, and always have. But for topics that bore me, where I don't see the point, why would I invest more than the minimum amount of effort to pass the grade, so that I can focus on things that I do care about? Of course I realise now that I was pubescent ignoramus, but you can't expect a teenager to realise that. That's the responsibility of the adults around them. Again, that is what I mean with teenage innocence.

Also, I remember one time another very bright classmate in middle school told me "being gifted is a mental illness of the parents". I don't know if he came up with that or if he stole it from somewhere, but it always stuck with me: a lot of kids (mostly guys, I suspect) who think they're oh so smart are really pampered by their parents - for one, it made me realise my mom praised my abilities way too much (luckily early enough to realise she was wrong quite often).

I can't find the article right now, but later I read somewhere that praising children for being gifted - "wow, you must be really smart to get this!" - discourages them from practising hard. Praising them for their accomplishments - "wow, you must have worked really hard to solve this!" - does the opposite.

Actually, `noreturn` is a standard part of c[1]. Can just specify as _Noreturn, or include a header that aliases it directly to noreturn. Don't know about c++, but it probably has it as [[noreturn]]?

I've slowly developed my own system to focus my efforts. It's mostly manual now but I'm automating it.

Daily: Reference my weekly goals and decide what I intend to do for the day. Look back on the previous day and pull over not-done items that I still need to do. It's very tactical execution. Examples are cleaning the house, finishing up taxes, or scheduling lunch with a friend.

Weekly: I write a summary of the areas in life I care about (work, family, social interactions, fitness, reading, volunteering) because my memory isn't great. I also reflect on the previous week's goals. Then I decide on goals for the next week. It's similar to iteration retro/planning at work. The big thing to watch for is intentions that show up multiple days but I don't end up executing. This is a sign that either I need to focus on it more, or stop wasting energy on it if it's not actually important. Examples of weekly goals are getting 7 hours of sleep, going to the gym 3 times, or building a feature in a side project.

Quarterly, or whenever I finish a big goal: Review the big picture goals. Are they the right goals? Are my weekly goals helping me achieve them? Examples of these are training for and running a 15k, completing a side project, or starting a band.
This Is the NEW Rimac C_Two – EXCLUSIVE FIRST LOOK
The author admitted the stronger-than-needed title in the first comment, but I'd like to make it clear when talking about practical personal security:

There are ~100,000 people in the world that would think to run a GPU password cracker on your Firefox master password hash, if they had access and wanted to snoop.

There are ~1,000,000,000 people that would think to open your browser and go to a website you use to try to gain access to it.

In some sense, although it's hard to quantify security, using a master password is 10,000x more effective than not.

I use to visit a barber twice a month to maintain my hair. The total time cost was 5 hrs/month, and a cost of $50/month. Now I shave my head 3 times a week. The total time cost is 8 minutes a shave, or 1.5 hours/month and a cost of $10/month.

The 3.hrs/month and $40/month extra is nice, but I wouldn't recommend it to someone as a productivity hack.
Yes, but in my creatine blend I also have psyllium powder. It acts as a laxative since raw flour can is a good way to get constipated.
I agree that there's nuance. Renewables and energy storage receive subsidies, yet there is no carbon tax to level the playing field with traditional fossil peakers (or even load following or base load fossil, for that matter).

Besides California, Arizona, Hawaii, Massachusetts, New
Jersey, New York, and Washington are also mandating utility scale energy storage. I anticipate additional states mandating the same in the near (1-3 years) future, which will contribute to driving down the cost of energy storage as manufacturing scales up. Time will tell.
Nuclear also needs to be paired with storage. It generates electricity at a constant rate. Typically it overproduces at night and underproduces during the day. Thus, storage is used to absorb the overproduction at night and augment underproduction during the day.

Granted, this kind of research may find the kind of quick-on, quick-off generation that's needed when there's a lot of renewable power in the mix.
>Can you elaborate on this? What do you mean by 'protected' and 'high entropy key'?

I can't be sure, but I believe GP is referring to how Firefox Sync originally encrypted all the data locally with a long key before uploading it to Mozilla servers. To sync your data onto a new device you would have to transfer the key, which was done by generating a 16 char temporary password at one end, and then typing it at the other. Your private key data would then be sent, encrypted, to the new device.

At some point, if memory serves, Mozilla decided this was too complicated for ordinary users, and now only stores your sync data protected by whatever password you type in - which is going to be potentially brute-forceable.
I agree as well. MS13 is certainly an issue, but it's being leveraged to sell a broader agenda about immigration. Not a fan of hacker news being pulled into that fray.

Hell of an endorsement.
Palentir exists because unconstitutional, illegal or retroactively legal, and in any case absolutely breathtakingly overreaching mass spying (including domestic spying via incidental collection) programs like Stellar Wind, Muscular, XKEYSCORE, Prism, etc exist. Palantir's job is to take massive amounts of data and make it intelligible using visualization and search tools. It makes money off of programs that either shouldn't exist or should be severely restricted.
Are you talking standard Google developer workstation specs? That's not much different than the thinkservers we use as desktops. But considerably beefier than what non-desktop devs might be accustomed to.
> Is this what molecular mimicry is ?

Yes, but it usually works the other way around, i.e. the immune system should not recognise the "specific gluten protein" because it looks like self. After all the microbe(?) that produces it is trying to survive by looking like its host, it isn't trying to induce thyroiditis in its host.

Another common case is mimicry of the A, B blood antigens and the Rhesus factor. Patients that are AB+ treat A,B and Rhesus factor as self and so can accept blood from any donor (i.e. AB+ is the universal recipient). In contrast, O- patients who do not treat A,B and Rhesus factor as self and due to mimicry will likely treat them as foreign bad (as opposed to foreign neutral), so if they receive a transfusion from any other blood type the immune system will attack the transfusion. Since O- lacks A,B and Rhesus it is the universal donor.

"Clean energy" is a bit of an overstatement, given that any fission reactor, no matter how advanced, will produce radiation out the wazoo. It will also irradiate the containment, leading to nuclear waste both in the construction of the reactor and the burned fuel.

The issue of nuclear waste hasn't been solved. Most countries do not have a proper storage site yet, and people understandably don't want to live anywhere near such a site.

I'd prefer solving that problem first, before creating incentives to produce ever more nuclear waste.

Yes. The waste issue has already been more or less solved.

Whether the cost can be made sufficiently cheap is another question. Inflation adjusted estimates have (somehow) been climbing since 60s when we actually built nuclear plants.

> I wonder how much of hunger is an emotion

I don't know what the scientific definition of emotion is (wikipedia seems to suggest there is no real consensus), but I am inclined to believe that at least part of the hunger process is an emotion, as it calls one to action, and it involves a desire for food. Rational thinking, typically seen as a contrast to emotions, does not do involve either.

And to phrase myself differently: I've noticed that I do sense hunger, as in all the sensory aspects of hunger (an empty stomach, consequences of low-blood sugar), but I don't feel hunger (the discomfort of having an empty stomach or low blood sugar, the craving for food). The latter feels more like an emotional aspect to me.

Interesting link to the ventromedial prefrontal cortex - it's not like my experience, but it reminds me of a few people I know.

> This can be incredibly debilitating because these people end up having to rely on “rational” thinking only and can take incredible amounts of time to make what seems to be a simple decision.

This makes a lot of sense to me for a number of reasons. There is nothing in rational thought that immediately calls to action. Yes, you can use it to reason and figure out truths and what you really want to do, but underlying all that is an emotional foundation of what you want. Without emotion, without wanting, rationality can give truths without leading to conclusions of what to do with those truths. There also is probably less of a sense of urgency without emotions, so one can take their time to weigh all the options (even though there might not be any time).
It is unfortunate that Mozilla does this without telling the user that you need a good password (or better, generating one for you), but you can just use a good password. 21 random base 64 characters is almost the strength of the 128-bit encryption. You can memorize it easily by writing it down (divide into three groups of seven) and entering it from the paper for two or three weeks. The trick is to try never to get it wrong (you will occasionally anyway, but try not to guess - the right answer eventually come to mind effortlessly before you look at the paper, which should be turned to not normally be visible). On linux, you can use `base64 < /dev/urandom` (or `tr -dc "[:graph:]" < /dev/urandom` which picks from a few more characters) to get the password.

One method of creating adversarial examples in a "black box" setting is to create and train a local model as a stand-in for the actual model using the inputs and outputs of the actual model.

Can you provide a citation for waste being solved? My understanding is that there is no long term storage facility, all waste is being stored in "temporary" facilities on site, and that any reactor capable of reprocessing nuclear waste ("burning it up") has never been operated at commercial scale.

It's not dishonest.

Electrical storage is a possible add-on to any power source, fossil fuels included.

But it's a significant pro if a source that don't require a s
storage solution. If economical, large scale storage were closer to being solved, you might be able to take it for granted. But not yet.

On the payment side of things, Stripe isn’t the only option available. The pro is that it has the fastest Onboarding workflow and a super slick api. The con is that you pay for it.

If you are margin conscious or your business revolves primarily around payments you can do better.

If that is the case for you, build with stripe through MVP stage but keep in mind you may want to swap out one day while building.

I’ve seen some niche businesses save 1% over stripe. That doesn’t apply to everyone but is frequently overlooked.
The technology to process the spent rods is far from being commercialized and widely available. So far, "spent rods" are accumulating all over the world, mostly in temporary storage. Some in unsuitable long term storage.

We can talk about acceptable nuclear waste production as soon as this changes...
Still no reason to give up hope.
A key point is that they have not measured the effect yet so it's not known whether the entanglement will be measured. Both papers describe a gravitational entanglement detection through measurement of evolution of a separate quantum phenomenon (e.g. nitrogen spin in a diamond lattice).

One challenge, which is commonly a problem for laboratory gravitational experiments, is that many other force interactions dominate over short distance scales (electric, magnetic, or even vibrational phonons) so excluding those is critical to showing the entanglement is gravitational. This means near perfect electrical, magnetic, and vibrational isolation... and probably measuring their coupling amplitude them to show that it is perfect.

As usual in experimental physics, the problem is not in detecting the effect, but in not detecting all the other interfering effects. It borders on proving a negative.
I started out with methylphenidate, but that gave me extremely high blood pressure and anxiety. It also completely removed my appetite Since about half a year I'm on lisdexamphetamine and it works a lot better, except for the hunger bit (although that also is a bit better).

Also, I can't drink coffee, not even a single cup in the morning, or I will end up skipping an entire night of sleep. That part is supposedly fairly unusual for AD(H)D so I'm wondering if I might be slightly misdiagnosed or something

EDIT: adderall = ritalin, vivanse = lisdexamphetamine, so my story has similarities to awsedrftg except my appetite is affected differently.
I use Ike for Android (Eisenhower time management matrix). It's adapted for people who can't use 'Delegate' for less important tasks:

Everything else I've tried for task management left me kinda paralysed trying to figure out what to do first and procrastinating.

The `Don't` quadrant is also a good place to record the things I do to procrastinate.

Keeping it all on my phone and not syncing it to a device that I actually use for work also stops me idly peeking at other tasks and loosing focus on what I need to finish (at which point I just take a break instead)

The app I use can have multiple matrices for work/home/whatever, but I tend to just usea single matrix and focus on managing all of my time.
