Yes, the headline is rather self-defeating. I studied persuasion techniques before the Internet got big and one of the trendy manipulation approaches then was to write an article titled "Why XXX" when XXX is some assertion you make, perhaps even with evidence but for which you don't actually offer an explanation (the reader never discovers why XXX, they are only that XXX is true, and why XXX is generally something people would be curious about). This technique naturally has become an arrow in the quiver of click-baiters but with click-bait sooo big now, using such bullshit is more likely to hurt a serious article than help it.

The proper title would be "we show human-generated carbon is sufficient to explain climate for the X many years", a significant claim by itself.
Does this have the ability to export? Data portability is pretty important when putting your knowledge in a spaced repetition system.

Also, does it support import from Anki? That might be a major selling point.

Edit: It looks like this stores data in localStorage? From the Privacy Policy [0] page:

> Mochi does not store any of your data on its servers. All content created in Mochi is stored on your computer.

While that certainly makes privacy easy, I would want to know that this doesn't "back up" my notes anywhere. If the storage was corrupted I would hate to lose my hard work.

It's a couple cents difference most of the time in my experience, not worth driving in a different direction or such for that.
Are you thinking of encryption or something? Because that doesn't prevent an eavesdropper knowing how much data was transferred, to and from whom, and when. That could all be sensitive information.
A lot of advanced economies have low, or even negative, birth rates and they don't have repressive policies nor have even particularly tried to make things that way. So there may be positive ways of encouraging a low birth rate without the need for harsh enforcement.
I do not disagree with you. When you learn the stuff, it is perfectly OK to explain equations with words and even write equations with words. But this is akin to the comments of a program. Once you get down to work, in a professional setting, all mathematics uses single-letter variables

(and I may add that all programming should do the same).

I also agree with you that starting math with set theory is utterly ridiculous and even harmful. You should start with
arithmetic and with geometry (obviously, using single-letter variables when needed).
Tom Scott had a pretty good video about them: https://www.youtube.com/watch?v=nl2mQ2HiJZc

Minor correction: Tom Scott's video is great, but I was actually thinking of Motherboard's video which talks about modern undersea cables: https://www.youtube.com/watch?v=iMAThVcqzuk
The pictures are lovely and the reflections profound. But much of the cited data here appears wrong. For instance, the article states (italicized): "six hundred helicopter pilots were killed" and yet it was only 600 helicopter pilots who _flew_ liquidator missions[1], two of which were killed in an piloting accident and none were registered killed from immediate radiation exposure[2], though at least one eventually died from cancer likely from this exposure[3]. Similarly a claim of "Over six hundred thousand people were directly involved in dealing with the aftermath of the Chernobyl explosion" is not supported by the evidence[4].

I don't mean any of this to lessen the enormity of what happened and the tremendous, noble effort made by the liquidators to remediate what was there at great personal cost. It's just good when making specific claims for those claims to be substantiated.

> Which is why I'm under the impression that if you really want to go to college, you should be trying to get into a PhD

This indicates that you do agree with the original article. It's just that you've accepted lowering the standards a full level across the board. A PhD today becomes equivalent to the masters degree from a few years ago, masters now equates to old bachelors, bachelors now equates to old HS diploma. But with continued lowering of standards at each level, what inevitably happens is that the next higher level becomes a job qualification as companies look for high quality candidates. So in your system, it will only take a few years before it will require everyone to go to school for a masters to even get a job. This system is broken.

Replace "random" with "local" and "seasonal." Biodiversity and crop rotation are not whimsical HN topics. They have been around for a while.

It works in my backyard garden and neighborhood urban CSA. The CSA could increase their production significantly if/when technology like this matures. Most of my local, seasonal produce needs can already be supported within a few block radius of my home.

I too appreciate the diversity of thought on HN... lots of experts to share their knowledge.
This is a natural and expected consequence of tax law - specifically provisions in ERISA, which sets out the rules for 401(k) plans.

Google wants their 401(k) to be as efficient and useful as possible for their employees, which tend toward being highly-paid engineers and other professionals. ERISA has some fairness provisions, which means that all employees must be subject to the same plan rules, and the plan must pass certain tests of "highly-compensated" employee participation limits compared to non-highly-compensated ones.

So if you have a bunch of engineers and some janitors, and you offer a large 401(k) match that engineers use and value and janitors don't, you wind up having to unwind some of the engineer contribution and matching in order to keep things "fair".

But, crucially, ERISA doesn't have say anything about who has to be an "employee" versus hired on as a contractor. So all the janitors and cafeteria workers become contractors, and now your 401(k) plan counts junior developers as the "non highly-compensated" comparison class, and your 401(k) plan passes muster again.

This affects Google a lot because their retirement plan is highly optimized for allowing highly-paid employees to save a ton of money in a tax efficient manner. It'd be difficult to craft a better plan, and from what I've heard they've even automated using a niche tax loophole as well ("mega-backdoor Roth" - after-tax 401(k) contribution followed by immediate Roth conversion, basically allows an extra $20k/yr or so in Roth contribution room).

To be fair, a Japanese convenience store is far more useful than a Starbucks. You can buy all kinds of things there, including healthy foods. Starbucks mostly just has overpriced coffee drinks and confections. At a conbini, you can get a healthy meal, and you can even microwave it there, you can get cash from the ATM, you can get a SIM card for your phone, etc. The two just aren't comparable.

This is a good piece in the sense that it will get Apple to do something I've wanted for a long time, which is to ban all the third party frameworks that developers are shipping in their apps.

They should either provide their own first party frameworks or select a handful of vetted partners that are allowed to provide those services to developers.
I do not intend to play down the importance of using docker carefully.

But the reproducible build aspect of the critic seems unnecessary to me: Isn't that more a concern of the packaging system? (no python scripter)

If your packaging systems supports version selection/locking, then use your packaging system right. If your packaging system cannot pin a version, how should docker solve this?

There is absolutely nothing wrong with building your own for personal projects, especially fun ones. The "don't reinvent the wheel" is more about how if you are ENGINEERING something, you should fully understand standards and best practices, how to use them, any configuration if needed, and composition of tools.

The professional will use and understand tools, it's the enthusiast who builds his own.

Nuclear looks bad if you restrict it to 1940's technology. Which we have done. We don't allow ourselves to dream any more when it comes to nuclear. We are still building the same plants we designed for submarines and bombs, and wondering why they aren't great for power. There are safer, cheaper, lower waste alternatives if we'd allow ourselves to try them (Thorium reactors, for example).

Does wind power really reduce the speed of the earth? I'd assume wind energy comes from the sun heating the atmosphere, so wind power is really just solar power in a different form.

Solar makes me really sad. The amount of land it consumes is staggering. Land that can't be used for other living things. I saw the most beautiful farmland in Italy this month smothered under sterile black waves of solar panels.
Hopefully this might help you: you can use outline.com to read the paywalled articles. I've only found like one website for which it doesn't work.
Start with the animal table:

Animal(animal_id PK, ... animal attributes)

No need for join tables or surrogate keys on these tables. The animal_id can serve as both the primary key and foreign key.

Dog(animal_id PK FK, ... dog only attributes)
Cat(animal_id PK FK, ... cat only attributes)

No need for surrogate key on pet, and don't forget the owner key:

Pet(owner_id PK FK, animal_id PK FK)

This allows multiple owners of one animal. If you don't want that you need a unique constraint on animal_id.
Related to (2) and (5), nuclear advocates also tend to assume that the designs being safe if in the hands of a competent, well-supplied, conscientious organization is enough. I used to think the same, but seeing how nuclear plants are neglected even in Western European countries, I no longer think that assumption can be maintained.
Should tech workers quit firms that don’t value privacy?
I'm a bit surprised they run it at all.
My apologies for being unclear.

I’m saying gin=gout. No matter how smart you are, if you see only one side you can’t possibly tell if it’s a good argument as you have nothing to compare it against. Following on from that, thanks to all our human cognitive biases and limitations, the information doesn’t even need to be totally one sided. 20th century democracy worked acceptably well because vested interests controlling newspapers etc. couldn’t dominate every aspect of political discourse everywhere all the time — although there are a few interesting examples of them dominating specific demographics, and as a result a whole bunch of people have been needlessly demonised, which is literally how I know this is a problem that can happen.
Once our house is paid off (about 8 more years), the same would be true for us and we are not living a Spartan lifestyle even now (I'm also using the 3.5% SWR for planning).

Even if I could shorten the time-to-full-retirement by a couple years, it wouldn't do me any particular good. I generally like my field and my job. I'm tied to the area (can't freely travel 25+% of the time) by virtue of having kids in 2nd and 4th grade. So, there's no mathematical/financial reason to pursue a more Spartan early-retirement-extreme or MMM-approved spending plan.

With that in mind, I find I'm able to enjoy the luxury expenditures, because they aren't taking us off our plan. We travel for a week each winter to "someplace warm". We travel to visit family quite freely. The kids engage in whatever activities they want to try, without worrying about the costs. We own an airplane. We have cleaners that come by every other week. We buy quality food. We give to charities that are meaningful to us (many with money, some with significant amounts of our time as well).

On the other hand, we cut our own grass, do 95+% of our own car maintenance, almost all of our home maintenance, and cook most of our own meals, because we value the savings and example it sets for our kids (especially around charity and talking through the value of money).

Yeah this argument doesn't hold water for me either. Learning new notation versus learning a special-cased exception to the normal semantics of an existing piece of notation feel like really comparable levels of cognitive overhead to me.

I don't think this is necessarily a bad choice overall but I find this particular line of reasoning a bit specious.

So, you must think one of two things, then:

1. Google, with all of the subject matter expertise they can avail themselves of, is completely wasting their money on this research that has no hope of success.

2. It'd be a bad thing for the world if we got cold fusion, but Google made some money off of it.

Is that right?
> it has destroyed the planet.

Using a hyperbole to justify another claim doesn't support that claim, it just sounds poetic to people who already believe it. What evidence do you have that hubris will ultimately kill all of us? Do you have a time frame for that prediction? If not, then it's a meaningless claim.
For me the happy medium is using the tools to get the job done, even if it entails building from scratch certain parts of the overall system.
I guess I'd have to say it's not a stack overflow question without those implementation details at any rate, and the whole point of a question like this is you are nowhere near getting implementation details together.

Land ownership has a long-term positive growth trend going back a thousand years in western society. It’s as stable an investment as one can make. Average rate of return in North Am over 50 years is about 5% per year.
Sure - my point is that you could design the experiment such that it could. It's much more scientific.
I agree with the general sentiment that this is a better stack overflow question. But, it's made it to the HN front page, so it deserves some discussion.

In general, there is no one-size-fits-all answer, because the answer is really driven by your data. Which brings up the most important point:

Your database is your application's source of truth. It must have the best data model, and will most likely outlast all source code that you write.

So don't try to model your data as if you're writing an object oriented application. Model your data at the database first, and then write your application to fit the model of your data. (Don't put the cart before the horse.)

Anyway, the general patterns in this case are:

- One table with lots of null columns

- Lots of tables that join: (Animal joins pet joins Dog/Cat/Fish)

- Separate tables (Dog/Cat/Fish, no joins)

All approaches have tradeoffs. The one big table approach will have "waste" with the null columns, but remember that joining pet to animal to dog has a penalty on read, and that separate tables has implementation complexity.

IMO: If your entities are known, (IE, you won't add a new type of animal every month,) and your database is read-heavy, go with a single table with null columns. Otherwise, you need to justify the complexity of multiple tables.
> I don't know what ^ means here

Logical conjugation ("and"). I should have used ¬ instead of ! to have been more conventional.

> Is it [flawed to deduce (abnormal brain -> psychopath) from (psychopath -> abnormal brain)]?

Yes. That they show the group has a brain anomaly, and hypothesise a mechanism which links it to the behaviour is not enough. It's plausible that people who possess this brain abnormality within the rest of the population commonly are not psychopaths. You aren't going to find that within "22 healthy non-offenders", the sample is too small.

> So they found a link, causal or not, between abnormalities and psychopathy

I don't dispute this.

> There seem to have been other studies too, from wikipedia "Blair, R. J. R. (2003). "Neurobiological basis of psychopathy".

They aren't making the conclusion that the brain anomaly implies psychopathy, they only theorise a biological basis for it being foundational.

Furthermore their article they states: "However, all of these studies, with the exception of one by (Raine et al, 2000), have been with violent offenders rather than individuals with psychopathy. [...] Indeed, neuropsychological work with individuals with psychopathy, unlike work with individuals who are violent, has repeatedly found frontal functioning to be intact (Kandel & Freed, 1989)." This gives more weight to the argument that it is flawed to make deductions primarily by studying incarcerated offenders.

Neuropsychological studies are often compromising. Scanning brains is expensive. I don't believe that these researchers are stupid, as you asked, but it would be silly to say that scientists never theorise without concrete proof. Neurobiology is still highly hypothetical, and experiments are often very limited by practical and ethical concerns.

Contractors for large companies[1] in the US almost always goes through staffing firms - direct contracts with independent contractors are comparatively rare. And even when you do want to bring on an independent contractor, you usually still have to route them through some designated third party staffing firm so that the contractual relationship is IC <-> Staffing Firm <-> Client. This is all due to fact that there are huge liability[2] concerns related to classifying someone as an IC but treating them as an employee.

As such, there's almost always an intermediate taking a cut of the actual rate, even if you're a contractor to the staffing agency.

Then you've got agency relationships, like where I work at now. I'm a salaried, full time employee for the agency I work for and I make about the regional median for my role. But I'm contracted out to clients (including Google) and bill hourly. Depending on the client and the specific roles I'm billing as for a given project, an hour of my time gets billed out anywhere from 2x - 6x what my fully loaded hourly cost is to my employer (salary + benefits + payroll taxes). So the cost to the client is certainly in line with your expectations, but it doesn't come back to me.

[1] You don't see this as frequently at the SME end of the market for many reasons, not least of which is the deliberate inefficiency and increased costs of such a structure.

Simply comparing lifespans is extremely misleading. We need to look at the potential risk associated with waste.

Solar panel waste: grind and reuse. Health risk: negligible.

Battery waste: empty, disassemble and reuse. Health risk: very moderate.

Nuclear waste: highly radioactive for thousands of years. No way to recovery leaks in the environment. Health risk: very high.
