I've always found that the big problem with insisting on go-big-or-go-home approaches to problems is that the odds are very good that you wind up landing on go home.

It might just be me - and I'm typing this while blearly-eyed tired - but it seems like insisting that systemic change is the only acceptable approach is a good way to make shockingly little progress. You wind up losing those all-or-nothing bets too often.

If the company helps some people and fails as a company, I'm going to call that a victory for humanity. I understand that some might choose to avoid a potential way to improve some lives out of a fear that it could backfire in some possible futures. I don't know what to say except that I disagree with that weighting of probabilities.

Having cooling be local as possible is exactly what matters. You might argue that a BedJet is silly, but the idea is similar in spirit [0]. The question is: why heat or cool the part of the air that makes contact with things that don't require it? It requires more energy and has costs like creating additional pollution.

I've had random ideas like wearing a wetsuit that regulates the temperature at right at skin-level, so something like this patch is both validation and a marked improvement.

> Having to carry a credit card balance isn’t much of a struggle.

Let's say you put $400 on a CC that has 18% interest rate. By paying only the minimum payment each month you end up paying a total of $598 after 4 years and 11 months. This means that for the next 4 years, a credit card is no longer a safe escape for you.

A better example would be an emergency Root Canal at $1,600. This would take you 12 years and 7 months to pay off.

Ask HN: What good use can I put my ~1500 sqft irregular basement to?
I have a decent sized based basement, just about 1500 sqft in all. It's irregular as in it is not one big hall. It is fully finished however & has many rooms, but some have concrete columns in them. It has a kitchen space (no appliances), bathroom (with running water, shower, toilet) & other rooms. The obvious solution would be to rent it out as a house to a bachelor or small family. But I want to explore if I can do something better. Also all my utilities like gas, water heater, water mains etc are housed in the basement, like bang in the middle. So renting seems inconvenient. The basement however has its own separate entrance. I can also enter from within the house. It's been lying vacant for the last 2+ years & I rarely ever use it or even go downstairs. I want to be able to make some use of it & hopefully earn a little side income. What are some options? I'm willing to invest a bit if necessary, but I have no idea where to start.

Are we living in the same world? Quantum mechanics, relativistic effects, mathematics ( game theory anyone? ) are blowing my mind. The world is more phantastic than anything one could imagine and we know that we don't know everything. The constraint to stay in this world is the least limiting for an interesting and compelling story.

I think the key to improving the US government is to bring the system closer to a one person, one vote situation. I believe the best way to achieve this would be to do the following: 1) Abolish the electoral college and go with the popular vote for the presidency. 2) Weight a senator's vote by the population of their state. So a senator from California would have more voting power than a senator from Alaska. 3) Draw congressional districts via an "I cut, you choose" type system [1]

Our current system has a number of problems. Swing states in presidential elections become the focus of presidential candidates and their platforms, even though those states are not home to the majority of the US population. Also, our current system creates weak links in the chain that are easier to exploit. For example, if you are a corporation looking to block legislation the most efficient means of doing so would be to contribute to the campaigns of the senators from smaller states. The average amount raised in 2012 by senate winners in California was $29.3M vs just $1.7M in Utah. It is much less expensive to influence smaller senate races, but the voting power a corporation would influence is the same. [2] If senate voting power was weighted by population, corporations or other groups would have to influence costlier senate races.

I think part of that is "Moneyball" has tended be more successful over the course of a 162 game season rather than the 5 or 7 game series of the playoffs where there can be a lot more variation in outcomes.

I also think the analytics quickly caught on across the league so the A's advantage was short lived. Now pretty much every team is very heavily invested in it.
Now I'm curious how, hundreds of years ago, engineers and architects determined what designs were viable.

Did they have quantitative data about materials' tensile strength, shear strength, etc.? If yes, what kind of math did they have for applying those data? If no, how did they safely design first-of-a-kind structures?
It matters because giving someone who can't manage money more money doesn't improve anything. Further, being semi-financially literate is probably a prerequisite for clawing your way out of poverty.

Dress-down / casual days seem to be promoted by people who are really into fashion, so that they can show off their new threads. They don't seem to realise or care that for many people clothes are just a boring practicality like toothpaste or umbrellas.

Only having a polarised wardrobe ( work or dog-walking ) I had nothing to fit that fashionable niche, so I decided to just wear the usual trousers / shirt / tie on Fridays and ignored the quizzical looks from the T-shirt&jeans brigade.

It's interesting the article says: ... even if there are no exogenous cues present, periodical patterns are still shown (1) indicating that these rhythms result from an internal time-keeping system. ... For humans, the most prominent circadian rhythm is the 24 h rhythm in the sleep-wake cycle.

I thought it's a well-studied fact that humans settle on a 30 hours sleep-wake cycle in constant light conditions?

> has aggressive ambitions on the world stage

Since its founding, the PRC has only fought two foreign wars, the last one being in 1979, in stark contrast to some other countries I could name. As a percentage of GDP, China spends about half what the US does on its military. It isn't China that has a dozen supercarrier fleets, it isn't China that has 600 overseas military bases, and it isn't China that has established military commands that span the Earth (China's territory falls under the American "Indo-Pacific Command," for example).

One could equally ask why the world should trust a company subject to the United States government. There is much more concrete evidence of American global surveillance than there is of Chinese global surveillance. The United States' foreign surveillance agency, the NSA, has a larger budget than all but a select few nations' militaries, not to mention intelligence services.

When it comes to surveillance, no one should trust any government (as a cute example, the Germans allowed the United States to build its massive new embassy right next to the Brandenburg Gate and the parliament building, and the United States repaid that kindness by installing equipment in the embassy to spy on the German parliament). China is no greater a worry than the United States is, and in practical terms, probably less of a worry. The concerns being expressed by the United States government at the moment are extremely hypocritical, and are driven by a larger fear of increasing Chinese global influence, which will eventually undermine the hegemonic position of the United States in the world.

Headline strongly debunked here:

https://twitter.com/p_millerd/status/1118071142311288838

Highlights:

"After some digging I found the 2016 appendix (again, 2017 not to be found). Only 12% of people couldn't actually pay the expense"

"Another survey question not highlighted actually gives some direct clarity on this question. It turns out only about 15% of people would not be able to cover a $400 expense [without impacting their ability to pay other bills]."

Note that "12% couldn't actually pay" is about equal to the 2017 official poverty rate of 12.3%. I don't find it surprising that people counted as "in poverty" would have problems covering a $400 immediate cash expense.
I didn't even sort of say that.
Some of the primitives exist for sharding within a single node, but to roll something the same as Citus would require a bit more work.

Citus is very much focused on simplifying all the extra work you'd have to do, to your application it still appears as if it is a single node–you don't have to wire together FDWs or teach your application to understand about different nodes/shards.

A lot of the work going into 12 we're pretty excited about at Citus because it can allow us to continue to tackle the scaling piece and leverage more of what it is in the box.
Throwing my own anecdote into the barrel:

Somehow, our HR provider company fucked up, and signed me up for the shittier of the two healthcare plans my employer provides, despite me signing up for the better version. All the paperwork shows that we had the good plan last year, but Aetna says we were on the shitty plan, with no out-of-pocket limit. To that end, our doctor's office is now billing us for $20k for a procedure my wife had to undergo.

We're lucky; we have $20k in savings. We can cover this without the bill going to collections and dinging our credit, while we deal with the god-awful chain of HR->provider->insurer, until we get paid back. I wonder how many of my coworkers couldn't.

I'd say most VC's are probably very interested in solutions for income inequality.

In the direction of getting their net worth equal to Bezos that is. In the other direction not so much perhaps.

But really what is people's obsession with "income inequality"?

Ya, the rich shouldn't run governments or be able to evade laws or abuse the poor (which is why we have governments who also perhaps should do more to care for the disadvanted), but other than that, if you have 10 dollars and I have one dollar it's preferable to both of us having 50 cents. I just don't get the obsession with "equality". Seems counterproductive. I truly am just confused by the obsession with it.
That's fascinating though, because Mirrorless cameras until so very recently were "the slow ones", and very much perceived as such, primarily and quite legitimately due to:

* refresh rate of EVF (vs optical viewfinder);

* Contrast Detect vs Phase detect autofocusing;

* as well as some design/control/menu choices

Even to this day, highest-end mirrorless are just starting to be trully competitive in the professional sport / action arena.

In other words, no active photographer I follow would use "mirrorless" as a universal shortcut slang for "fast, speedy, responsive". On the contrary...

So I don't feel it's a case of "every article needs to work hard to dispell myths"; but rather, an article not actively, for no seemingly good reason, starting wrong myths from scratch :).
> It is scary stuff as I don't think I can make a visit to a doctor for a non checkup type situation (injury) without the bill being more than $400.*

> And I have "good" insurance.

Well, not really, because even a crappy HMO gives you better guarantees than that.

You have a “good” insurance plan probably in the sense that providing the illusion of choice while heavily exposing you to cost for “covered” services is widely sold as “better” than a slight reduction in mostly illusory choice with far performance on the risk protection function that is the whole reason to buy insurance.
If the medieval French could, they would certainly build Notre Dame with steel and glass.

But they couldn't and so they built it with stone and misshapen bits of coloured glass. That's part of the achievement and of what makes it a monument. Otherwise the Luxor in Vegas would be an acceptable substitute for the giant piles of stones in Giza.
It seems more like a cumulative effect than one cause. Rising costs [of housing, health care, education, etc], stagnant wages, loss of retirement support, increased dependence on credit, recessions, and a continued disposable consumerism, all have an effect not just on personal wealth, but what one's wealth can do. And I don't think people were significantly more financially literate 20 years ago.
Burning copyright to the ground would be a significant improvement over the mess we have now. Artificial scarcity enriches a few at the expense of the many; hardly a desirable state of affairs.

Not to mention that if you're in that <$40,000 income bracket, you're almost guaranteed driving a car that has a very high probability of needing a $400 (or worse) repair quite regularly. You also likely live somewhere where you need that car functioning to get to work.
What a convenient rumor to start while their stock price is getting clobbered.
Indeed. Most of my family falls into both categories.

One the one hand it is infuriating to see them pay more for everything they buy because they are paying interest on everything they buy partly because they buy stuff they don't need or buy it sooner than they need to.

On the other hand there are incredible cultural pressures in america to spend spend spend and get newer/better stuff than you need (cars, houses, phones) and almost no cultural pressure to be prudent and responsible.

Probably doesn't help that there is a whole 'industry' whose only function is to capture 5-35% of the income of the poor and distribute it to the rich.
Indeed it may somewhat be a result of financial illiteracy, but today's young people are significantly better educated than previous generations (https://en.wikipedia.org/wiki/Educational_attainment_in_the_...).

With the cost of education, healthcare, and housing all rising significantly faster than inflation, it's possibly just harder for many to save up that emergency fund. Indeed, it's particularly difficult to justify having an emergency fund if you're also facing five figure 8% interest student loans.
I feel like this might be coming from a position far above minimum wage, because in practice the poor aren't that stupid. You get trapped in cycles of incredible housing expenses keeping you in constant short term debt and the lack of income leading you to constantly seek new revenue sources, but being in that condition is inherently expensive and money in is always trying to fill up a bucket with a hole in it.
Paypal does its best to make all its emails look like phishing by using a quadrizillion of different origins (stuff like paypal-service.com, paypal-australia.com.au, paypalcustomercommunication.com etc.) and routing links through another set of phishy origins and/or external third parties, and to top it all off they give bogus advice like "You can see this email is from Paypal because we are using your proper first and last name".

A lot of the bigger companies are guilty of this, Google is probably one of the few exceptions, since emails from Google tend to actually originate from ...@google.com, and their logins are all handled through accounts.google.com, unlike e.g. Microsoft which still has a handful of different login portals for the same account on non-microsoft.com domains (such as "msauth.net").

E.g. Dropbox sends emails from half a dozen or so origins, Microsoft uses a bunch, too, including shit like "microsoftmail.com" which rivals some of Paypal's choices for phishiness.

A correction to those The Verge articles: the Remembrance Agent was actually by Bradley Rhodes, not Thad Starner.

It's interesting that people are still using Twiddlers. At the time that Starner, Rhodes, and others at MIT were first experimenting with what happens when computer technology is always head-up, a typical kit was a Twiddler, Private Eye (mounted on eyeglasses/goggles or hat), and a computer that was hefty by today's standards. Steve Mann had some earlier, unique gear.

Rhodes had the hefty computer in a soft cube-shaped shoulder bag that looked like maybe it was a insulated lunchbox, with cables/tubes coming out of it, and going into clothing. He said it took a while to learn that some people were afraid to ask about it or say anything, because they thought it was a medical device.

It's great that the computer part can now be done with a tiny $5 Raspi0w. Or with smartphone hardware. (For the smartphone, preferably reflashed with PostmarketOS GNU/Linux, and adding HUD and some kind of discreet command input. Maybe you could do the input with finger on smartphone touchscreen in your pocket, and then you only need to add a HUD on BT/USB. Maybe more battery.)
> Real estate is a kind of property that one owns at the mercy of the state. It is not something that anyone -- other than sovereign governments -- really own.

That would be true if that tax was only on the value of the land. But it's not. The value of the structure on that land is part of the tax.
Ah, yes, the ultimate "fuck you, got mine" sentiment in action: benefiting from the level of unprecedented wealth and prosperity we live in, which came from humanity spreading around the globe and ingeniously utilizing its resources, and now wanting to pull the ladder of life itself up away from the next generation.

Remember, rising empires build roads, and declining empires build walls. The way out of the current climate crisis is not to wall off what we have and die in stasis; I'm afraid the only way out is through, and we're not going to get there by dwindling our own population.
I think it's more about aligning incentives with investors. Money put into a non-profit is a full write-off and so can really only have altruistic motivations. For-profit allows for investments that are motivated by a mixture of altruism and self-interest, which (for better or worse) allows for a much larger supply of capital.
Not when a minimum wage isn't a living wage. That sort of by definition means you don't have enough extra to save.
What industry are you referring to?
You are correct, and what you state with disparaging feeling, I state with glee. The joy of creation should not put food on the table. You should have to work like the rest of us. If you have no time, make time and budget to create in the time you do get.
