> Disagree, in my favorite language you just add "?" to the possibly-erroring function et voilá, error propagated

And one of the first things I had to learn in rust was how make this happen with different error types. After that it was pretty much the same as exceptions. What functions return errors is a little more obvious, at the cost of extra boiler plate (most stuff being Result<...> anyway)

Checked exceptions Java style could be a perfect balance with just a few modifications. Compiler/IDE should mostly know whats thrown where, so specifying it manually should rarely be necessary. And still could visualize what can fail and with what errors.
I'll put Soros down as one of the traders who definitely did have a lot of insight.
Yeah, torn down to make units to sell (which makes sense given the incentives).
That's not necessarily true. Amazon may provide cheaper distribution/shipping thereby reducing the end-user price even though the supplier is paid the same.

Amazon is also increasing the overall reach of each supplier thereby increasing demand and sales volume.

It also opens up new arbitrage opportunities. For some people, the convenience of Amazon is worth paying a higher price for certain items. Due to those consumers, sellers like this can make substantial profit: https://www.youtube.com/watch?v=vzrtdUCsYTQ

The behavior shown in the video is a great example of the 'pie' actually expanding. The arbitrage seller is creating demand at Walmart and other local businesses, Amazon is making some profit, and the end-buyer is also better off since they gained the convenience which they likely value > the original price + arbitrage margin.
We are talking about Canada, not the world. Also 3 years, not 30 years.

Also the poverty line here is totally different.
It does, thanks! This does indeed look like good stuff. It is true that font-rs is not fully optimized for large areas, as it depends on memory fill and cumulative sum for each pixel. These are not hugely expensive, but it sounds like a sophisticated approach (as taken by Blend2D) can do better. Happy to see the work.
I'm pretty sure this is fixed in the latest version. I can copy the user/pass directly from the extension menu. It also works fine on Microsoft and Google.
It's a testament to two things:

1. Biology is hard, unimaginably harder than writing a piece of software, for example.

2. The way research is funded is horribly inefficient and in serious need of an overhaul. I'm all for pouring more money into research, but too much research takes place in bloated universities and too little money trickles down to the scientist doing the actual work.
As to why I'm commenting on it: because it was submitted for our comment, and this is my comment.

Was it? Is there any particular expectation that HN users must comment on stories, as opposed to simply reading them and gaining whatever value they gain from that exercise?

I don't know about you, but I certainly don't feel compelled to comment on every HN post. And judging by how many posts hit the /newest page and disappear with 0 comments, I don't think I'm alone in that...
Software then moves a lot slower, because most user applications are pretty bad at using more than one core efficiently; and these CPUs have been mainstream for some 15 years now.

The hardware is certainly much more capable than what little use the software tends to make of it.
SpaceX fires up Falcon Heavy Block 5 for the first time, launch date announced
> The article isn't advocating that you buy a coffee every single day. It's saying a. focus on larger issues and b. it's okay to do a little self care and a little self indulgence.

I agree. But I don't think the people making the argument for spending less money on coffee are arguing against those two things.

They are not talking about never going to a Starbucks. As you point out, there are circumstances where buying a latte can provide a lot of value. But those situations don't account for most of the money being spent on $5+ lattes. In most cases, it's people in poor financial health, who are not saving enough, and who spend a significant amount on minor luxuries which don't actually contribute meaningfully to their lives. They do it just out of habit. It feels like a sacrifice to stop, but only because it requires giving up a habit. All habits are hard to give up.
Unless we come up with some objective criteria to compare touchpads, this may be a subjective judgement.

Nevertheless, there are a large volume of people who subjectively believe Apple's touchpads 'feel' better and more precise, beyond just multi touch gestures.

You could compare it to the handling of a car. There is some consensus luxury cars feel better to drive.
Batteries have cycle life of thousands of cycles so you can't really compare the costs of production and storage directly.

1. I would like if this had a citation. Any citation.

2. I'd like to see a rather more sophisticated breakdown of where the poverty has been reduced. Has poverty gone done universally across all groups? Including First Nations? This opinion piece puts a lot of emphasis on grassroots community-level change starting the ball rolling, but has that actually happened on the Prairies or the Atlantic provinces?
> We can't have it both ways. Either we have a "the rules are the rules" approach or we have a principled approach. You can't appeal to the "spirit" of a soulless ruleset.

Sure you can. A judge could rule that you're breaking the spirit of the law issue appropriate fines. If this became common practice, people and companies would stop utilizing so many "loopholes".
I'm not against LGBT representation at all. I've just had the thought that 1/4 (lead) characters on shows I watch seem to be LGBT. And that's probably an exaggeration, like someone else said. I do think it's important that if a screenwriter is going to write a gay character into the story, he do it with purpose and feeling rather than just to check a box. Make the viewer empathize and feel for the character.

Currently watching Dear White People. It's great. Most racial minorities seem well-represented these days. Off the top of my head, Muslim-Americans and Middle-Easterners could use some more representation. Indians too.
That is mentioned as one of the reasons in the article.
If you're unclear on who is peaceful and who is aggressive, take a look at whose army is in whose country.

Motel 6 to Pay $12M after Improperly Giving Guest Lists to ICE
It doesn't matter, 2% or 3% is just splitting hairs. I also apparently underestimated the percent of US GDP going to federal taxes; it's around 19%, not 10%. So there is still more a lot more new tax money coming in than is necessary to service the new debt.

"3.9% of GDP invested initially"
How is this investing 3.9% of GDP? It costs 0$ in investment for the government to issue new bonds. The only way federal debt costs the country is in the interest spent on servicing it. As long as the tax base increases faster than the interest spent on servicing debt (and also accounting for population growth) there is no economic problem with increasing the federal debt.

And again, I am not arguing that the things we are spending the government money on are rational. I think we could do a lot better by cutting military spending and increasing funding for non-military research and infrastructure without deficit spending (which is certainly possible). But technically the current deficit spending is not unsustainable
Author here. What a surprise to open HN and see this on the front page :) Happy to answer any questions.
It's fine for unemployment to exist - for people to be seeking work but not finding it. The idiotic part is that we've structured everything so the reality is, for most people, continued unemployment leads to poverty.
The data brought to light by Factfulness also contradicts this NYT article, which claims the US is not addressing poverty. In fact, the US and most western nations -- and indeed the world as a whole -- are getting richer with less poverty. Already extreme poverty is virtually nonexistent in Level 4 nations like the US.
Ask HN: We have 5 dimensions: air, sea, land, space, and cyber.  What's next?
Most people think that there are four classical dimensions in nature. They include air, sea, land, and space.

Then came the fifth dimension: cyberspace. What will be next? Some people believe that brain-computer interface might be it. Or could it be something else like quantum cyberspace? Does anyone have a guess/hypothesis on where evolution is going? Any data that suggests something?
City Skylines does have one form of pollution you didn't mention: Noise pollution. People next to busy streets get sick and die from the noise.

Water pollution generally only happens when a player starts sucking out too much water from a river and reverses its flow.

I do agree that the mass dieoffs from a single drop of polluted water are probably too much. A significant production drop as people are under a boil water advisory at first might be better, and only becoming a major die off if you neglect to fix the problem. The water treatment plant could be more interesting if people were always dying at a low/modest rate from even "clean" river water until you built it.
How to Speak Up in a Meeting, and When to Hold Back
802.11n? It's 2019, for crying out loud, I can understand not having WiFi 6 yet, but this is way too retro...

I was looking at a ThinkPad X! Extreme yesterday. Better specs (8th gen Intel CPU, dual M.2 slots, GeForce 1050, 802.11ac of course) for less money. The System76 laptops also look more modern.
I may be wrong in the interpretation, but LCOE would seem to apply only to the actual capacity, and not the grid‘s entire throughput.

Yet batteries would only be needed for a fraction of the installed power, to adjust for fluctuations in supply and demand. Most power would never see the battery in such a grid.

And, of course, batteries are only one of multiple strategies to get supply and demand to equalize. Smart consumers is probably the most underdeveloped now, from cars that would charging (and possibly even discharge into the grid if your schedule allows), washing machines picking the best times when possible, or cooling and heating working with their respective reservoirs.

Automatic server scaling and healing on DigitalOcean
Depends where you are. Pretty sure I've made under $25/hr most of my development career. And that was just fine, in the Atlantic City, NJ area, because the cost of living was pretty low and I had no interest in moving or commuting to a big city.

EDIT: Although I guess it might've been a bit more if you include the value of health insurance and such.
> This says that if you take free energy, store it in batteries, and pull it back out later, you will have to pay $187/MWh.

Yes, but with that cost you can repeat that thousands of times instead of just once.

You're demanding that everyone else has to show that they're ready to abandon their principles, lest you judge them instransigent and unreasonable. What changes have you made to your worldview, without seeing something significant change?

Probably never: your views are shaped by observations of concrete realities and reflections on the consequences of those. And unless those realities change or you get new information, you couldn't come up with a coherent set of new views if you wanted to.

> It's not a rhetorical question if there are multiple valid answers

It's still a question intended for rhetorical effect. I wasn't saying that makes it invalid, it's just annoying if you're repeating it while dismissing the answer given.

Your ability to eat and pay rent should not be dependent on your income as a game developer. You know there are some professions where the pay is so low that yes, people really need to live paycheck to paycheck. Game developers do not, sorry.
Unless you're planning to go into a career in equities/fixed-income research, or trading, I don't see why you'd want a Bloomberg terminal. I don't even know if they make subscriptions available for individuals.

An MBA's value isn't based on surface-level stuff like coursework on marketing or strategy; you can get that anywhere. It's in the recruitment network that a high-ranking school attracts. It's the difference between having Google or Goldman send alums to campus to interview people, and applying online into the black box of an Application Tracking System.
Blu-Ray audio and video quality is significantly better than streaming which is why I still subscribe. Streaming is certainly more convenient for stuff that doesn't really need very high quality though.
Hm, kind of like race versus ethnicity.

You should check it out more! I love it. There are some similarities to the way your project is put together.
Or they realize the problem isn’t fixed if they give away their money. It’s structural — why give up what you’ve gotten if it won’t fix anything?

That's not what Damore actually said but he was fired under "creating a hostile workplace" which is up to interpretation of a private company.

Or "Why hasn't our IT/infosec department detecting the hacking that has presumably already happened?"
I agree, but I think it's worth clarifying:

I think Christians have done ourselves no favors with the imprecision of the use of the word "Faith." One finds in the Bible or Augustine or Aquinas, or more recently CS Lewis, they all use a particular, consistent meaning of the word that is different from the common meaning. I think what you mention (i.e., faith is the continuing affirmation in something that has been tested) is consistent with that. Unfortunately, many people have used it to mean something like credulity, superstition or blindness (see, for example, the expression "You have to take it on faith"). I think it's important to communicate that Faith is not a thing we do for good luck like some superstition, and it's not a thing that we prefer like one flavor of ice cream to another, nor is it something that simply works for us like some kind of work out routine - that is, something that is useful but ultimately arbitrary.
A multi million dollars tech company with tens of employees cannot run a sane infrastructure with a single digit of servers.

For a trivial website in production: 2 web servers + 1 database + 1 replica.

For internal tooling: 1 CI and build server + 2 development and testing servers + 1 storage, file share, ftp server + 1 backup server.

For desktop support: At least 1 server for DHCP, DNS, Active Directory + firewall + router.

That's already 10 servers and not counting networking equipment. Less than that and you're cutting corners.
That's how the economy works. Everybody watches each other and makes adjustments. And with the financial sector being so big there are also a lot of feedback loops.
The author's point is that decades of wage stagnation combined with tremendous inflation in big ticket items (housing, healthcare, education) have made it impossible for the bottom 80% to save. That cohort will be perpetually broke because of housing, healthcare, and education. The other 20% won't notice the difference.

Rent? Enjoy annual increases that eclipse your wage growth.

Bought a home with rented money? You still have to pay the mortgage even if you get laid off. You still owe the same amount even if property values tank. If you deplete your savings you might face foreclosure, which, compounded with a down market could wipe out your equity. Most home"owners" don't understand these risks.

Major illness or emergency? Your insurance plan is tied to your job. A full time job in a competitive field at a generous company will get you decent, affordable coverage. A full time job at a company that's circling the drain or is focused on shareholder value will get you expensive coverage that doesn't cover much. A part-time job means you get to look for health insurance on your own, a process that confounds even healthcare economists, and the quality of your options varies greatly from state to state. This is where you'll eventually end up anyway, since you'll be too sick to work. Your company will find a way to fire you. Once you deplete your savings, you might qualify for aid, but not much.

Your parent/uncle/niece/unmarried SO needs money to treat a chronic illness? Government assistance won't cover everything. Neither will crowd-begging or their savings. Or yours.

Have young kids? Daycare costs $15k-30k per year. Kindergarten is only 4-5 hours a day, elementary school is 6-7 hours. One parent can only work part time--very, very close to home, or drops out of the workforce for 10+ years. This destroys their career and lifetime earnings.

Kids want to go to college? Financial aid is "need based". Live on the coast where your salary is high but so is the rent on your modest home? Too bad, need is not regionally adjusted. Are you poor and broke? OK, you have a need. Decades ago your child would receive grants, now they'll receive grants and loans. Hopefully you planned and parented well so they go to an in-state state school, otherwise they end up shackled to a mountain of debt.

Frugality won't save you. Don't be stupid and live way beyond your means, but a latte a day doesn't matter. The most important thing is to get in the top 20% on one salary and hope you stay there.
There are situations where it makes sense to create a shared chart that can be used by multiple teams to implement their services, but to be extensible enough to work with other common services. For example, cert-manager and external-dns. Or for a local environment, you may want to use Minio for AWS-compatible storage but Service Catalog and AWS Service Broker for other environments.
Capex for lithium batteries is on the order of $100/kWh (kilo- not mega-). Other battery technologies will not be much better. You are confusing amortized cycle costs for capex costs.
