Well sure, but the particle board thing tcompares to getting a cheap Android budget model though. Not last year's flagship at 40% of the cost. (Well, last year's iPhone hasn't dropped quite that much, but in the Android world they often do with some smart shopping.)

It changed my life and it was absolutely for the better and it was absolutely a book I shared with most all of my future sales pros. I would not be where I am today whatsoever.
I've been stuck on the iPhone SE since release and refuse to switch even though the home button is broken. I would consider switching to Android if a manufacturer released a premium phone with SE-like dimensions. There's literally nothing on the market with a decent spec anymore. "Compact" phones now have screens that are > 6 inches.

How many cases have Judicial Watch lost or been thrown out for not being legitimate? (Spoiler, they have a beyond excellent record)
I'm not sure we have any reason to believe this. There are two reasons given:

1. families had fewer kids after the 2008 recession.

2. Alternative forms of education.

The latter will be good news, if it does displaced old colleges. The former, which is waaay earlier in the article and therefore probably the more important cause (in the opinion of this article) could be swung at any moment by a change in immigration, welfare, or regulatory policies on state (for the latter two) or Federal levels.

I don't see much reason to take this prediction seriously. Are private investments or bonds of some kind in these institutions tanking?

Show HN: Man Pillows?
Because communism is inherently a violent and paranoid ideology. It's blatantly obvious even in the foundational literature from Marx. Marx openly advocated violence and threatened violence against anyone who was opposed to the proletariat.

Not only that, but he construed a framework in which anything opposing the proletariat, including "class antagonisms" that could be literally anything, should be opposed with force or the threat of force. Things like religion, private property, or anything that is not for the revolution is necessarily considered against the revolution.

When the foundation of a worldview is steeped in violence and using violence to get your political way, it's no surprise that the implementation of that worldview results in bloodshed and power vacuums.
It all goes in a circle though: why did city governments sanction taxi cartels (by issuing a fixed number of medallions)?

Because if anyone can be a taxi anytime (aka open market), then you get a race to the bottom, both in quality and availability. Then there isn't a steady supply and a lot of collateral problems (accidents, crime, etc). The solution a century ago was to regulate: limited number of taxis and minimum driver qualifications. In the days before apps and routing, it meant that there were taxis available most of the time, except for maybe at peak times.

My point is that taxis are an extremely good example of why you need regulation. Uber and Lyft will succeed to the point they can replace that regulation (cheap enough fares, good enough cars and drivers).

You could also argue that Uber and Lyft are controlling the taxi market because they don't let drivers set their own fare. From the point of view of the driver, taxi-driving is an Uber-Lyft-sanctioned cartel right now.

Physicians - always on the go, need access to calendar, reference apps, communication (messages, email)... to me, having a fast phone with a big screen is a no-brainer.
Interesting. What's the rationale?
Right, makes sense! In the future you might want to consider abstracting the storage layer out, so you could add a localStorage endpoint as well. I'm not sure if there's a big enough market to warrant that, but perhaps there is for some folks (people applying for cybersecurity type jobs, for example).

Fine, but laying off people who don’t work out is an ongoing process in all companies. If people haven’t already been let go as a part of the company’s existing management review process, what changed suddenly that the company can suddenly lay off a bunch of people in one go and “improve?”

Another way to think about it is that everyone has some productivity, some contribution to the company’s net progress. If someone’s contribution is negative, they should already have been let go.

If their contribution is less than others, maybe “bottom 10%,” but it is still positive, you may be letting go a relatively poor performer in a round of layoffs, but you’re still shedding a person with a positive contribution.

You are going to be worse off, no matter how you sugar-coat it.
I gave my old watch to my girlfriend and having her use it for sleep tracking has been super helpful in tackling her sleep issues. Once she saw her numbers for deep sleep every night, it kind of kicked her into action to address the root cause. Sometimes just quantifying something is really helpful. It's also been somewhat useful in comparing the various approaches (prescriptions, marijuana, vitamins, exercise, etc etc), because sometimes it's hard to judge how good of sleep you got one night if you're constantly getting terrible sleep every other night.
You have links to any published research? Is it published separately or as part of larger studies? I'm having trouble finding simple numbers.

Such numbers would be useful for determining a theoretical floor for gas, nuclear, etc providing baseline capacity.
Yes and no. I would love to use Slack over uChat, don't get me wrong, but uChat is a skin/integration of an enterprise chat app not a greenfield build.

Look familiar? https://mattermost.com/
Slack was evaluated a few times. The reason it was initially rejected when we first considered it is because it wasn't able to handle our scale at the time and the team over at Slack was not interested in prioritizing scaling for us over other things on their product roadmap.
thank you for the explanation
Glad to hear it!

Personally, I absolutely hate 3D Touch. I've never been able to get the hang of the distinction between it and a long press, so something as simple as moving apps around or selecting a character with an umlaut is incredibly frustrating.
Interestingly, your comment reminded me that I wanted to look into Mattermost and they have the Uber logo listed on their front page...
This is very cool.

Tangent idea: it seems like the way we describe Earth's movement in space (rotation + orbit + precesion) is akin to the image of the hand that draws itself; where instead of describing the whole trajectory, we instead describe it in terms of "circular components" (rotation, orbit and precesion, yes I'm aware the orbit is not perfectly circular).

The closest visualization of Earth's "full trajectory" in space, that I've been able to find, is a video on YouTube (https://youtu.be/0jHsq36_NTU), which unfortunately is a bit exaggerated and not very accurate.

Has anyone seen something better than the above?
There's a big difference between decent, ergononic equipment and high luxury though. The most expensive flagship phones compare to high luxury, not basic, functional, ergononic environments.
Citation? Can you find the analysis that a recession would help Trump get re-elected?

People fight against taxes.

Now imagine how much harder they would fight if the tax man wanted 100% of their income and wealth.

Now imagine what it takes for the tax man to overcome that resistance.

Purges, paranoia, and violence sounds like just the start.

All that matters is the economics.

We're at about the point of parity; BEVs cost more initially, but over the life of the vehicle, cost about the same as a comparable ICE. Whether you spend more or less comes down to how you use it.

Petro and ICE has been getting more expensive. Batteries and renewables have been getting less expensive, with a clear path for continued progress. It doesn't take a genius to figure out what's going to happen.

The infrastructure will come. Vehicle ownership costs, on average, 9 grand a year for Americans. So a BEV that can save even a modest fraction - say 20% - of that cost has a fairly large budget to work with for installing NEMA-50s where they're needed. On-street solutions are being developed, including some being deployed in the UK.

I don't think there will ever be a significant number of people doing fast-charge only.
At least that in the summer and spring time. Not so much during the winter.

The word that fits here is "lifestyle."

The iPhone is a lifestyle product. It does a lot of things, but it does some of them quite poorly.

The new camera is better than it used to be, but it's still a long way of short of the quality you'd expect from a high-end professional photo studio camera.

As a lifestyle product, the important factor is the narrative that buying it will put you within reach of that professional creative lifestyle.

In a sense it will, if your definition is limited to lifestyle social sites like IG and FB.

But in a more honest and realistic sense it won't, because it lacks the quality and the flexibility of real professional equipment. A good DSLR + glass will still kill it, and medium format - which is what the most successful full-time studio pros are likely to use - will absolutely destroy it.

There are still situations where that high end is needed. Fashion, ads, and high-end portraiture and photojournalism all rely on it. I don't think studio photographers working in those fields are going to be moving to an iPhone any time soon.

> As a consumer, do you want a bill for 2 cents a kWh? Or one for 15 cents a kWh?

If that energy produces zero carbon then I'll take the later. But we're also only talking a difference of 7c for PV and 10c for nuclear and competitive prices for coal and natural gas. I'll gladly pay more for the nuclear than pay less for coal and natural gas.
I have. If someone can’t save a few hundred bucks a month something is wrong.

Let’s use Dallas TX for example, even just waiting on tables you can make at least twice rent. Forgo a car and you’d be able to pocket $500 / mo or more if one was frugal.

It’s even more critical to save when at the bottom of the economic ladder, because it allows one freedom to pursue or invest in other opportunities (paying for school, moving, weathering unemployment, etc.)
Huh?

As I see it, "[i]f you don't know who you can trust to provide a trustworthy proxy service", you distribute trust among multiple providers, such that they must collaborate to pwn you. That's the basis of Tor. And you can do something similar, albeit far weaker, by using nested chains of VPN services.
They won't pay you, unless you're literally running part of the power grid.

> Generate surplus when the sun is shining or wind is especially strong, run from storage when demand exceeds supply, build both until there's enough.

That's the idea, but the battery capacity required would be enormous:

Batteries don't seem likely for a cost-effective replacement, but alternatives may develop down the road.

Maybe, but the problem is that in a restructure like this the high performers often leave in protest to the culture problems that a restructure creates and austerity measures.

Often though they don't cull low performers, they give each department a budget or a head count they have to hit. A department made up of high performers will have to cull a high performer to hit budget, a department which is overloaded will become more overloaded and people will quit in response.

In a company the size of Uber a restructure is often a pretty blunt instrument.
This reads like marketing material shoehorned into a soft-peddled criticism about human rights in order to generate buzz. What stretched my suspension of disbelief more than anything is that the author seems to think that people use this product in production, which AFAICT, no one really does.
What you describe more or less exists here in Spain. The (mandatory) national ID is a NFC smart card with a PKI key [1]. With that (among a lot of other things) I can login into my regional government website [2] and look at my (single-payer) healthcare medical history, download it, see who has requested access to it, restrict access to some parts of it, make an appointment, ask for a new doctor, etc. etc. Of course it is sadly more closed-source, proprietary, lowest-bidder work than your vision, but at least the idea is out there and available for millions of people already.

One thing I've learned time and time again in software is if something seems super simple on the surface, it almost always means there was a hell of a lot of engineering and attention to detail to make it seem that simple.
I guess if apartment renters have no easy alternative the city could charge a high premium, and it would be worth it to have overnight charging instead of chasing down a station on your own time.
Anyone else, from an industrial design standpoint, think the triple-camera nonsense is revolting to look at?
Then at least preform a trial in absentia rather than just putting them on the kill list.
...because it is different? If you're a small fry, you hurt fewer people, and any claims that it's a survival necessity are at least plausible. It's also quite likely that people you hurt are actually worse than you, as is possible with Greedo.

If you do the same as the director of FBI, _excuse me_, Lord of the Sith, things are quite different.

Edit: but also, Uber and Kalanick were never small fries. So that's where it breaks down.
Datomic with Rich Hickey
I agree, but they're both important moral failures that should be challenged.

Here's a wee anecdote. When I was in my teens and early twenties (read that as late 80's) I was an active member of CND, the SNP and Scotland Out of NATO. I was active in the NUS (National Union of Students) as well and even organised a protest and student strike at my Scottish shithole of a college in Perth - having managed to drum up around 400 students to march upon the Tory offices in Perth to demonstrate against cuts to student grants and burseries.

During this time I was never arrested or apprehended by the Police. In fact I've never been arrested or apprehended and as far as I know don't have a criminal or civil violation record (except maybe a handful of traffic violations - speeding, and a driving without due care and attention when I was 26 [reading my map]).

After I left college, and despite being qualified for many jobs, the interviews came and went over around 6-7 years and I wondered why? Until it came to light there was an organisation called the Economic League[0] which manually compiled lists of UK activists and fed them to many organisations as a form of blacklisting.

Whilst I was never able to establish that I might have been on their list, I had a fairly strong suspicion, with hindsight, I was listed. There's no way that the sort of jobs I was applying for, where right up until the last minute, the offers were withdrawn with no explanation.

I had a low-cost Renault once, the 1981 Le Car. Never again.
A lot of that is just technological maturity, I think. When smartphones first arrived, there were many, many, obvious upgrades that would make the experience better for the user of the device.

This is the golden age of any technology; the lack of something great, and seeing it approach from the horizon, then repeating with the next thing.

Smartphones definitely seem to be converging on a form factor and a feature set. This is what happened to "feature" phones that we all had just before the smartphone became available. Do you remember any features you were dying to have in your next flip-phone? I don't. They had matured.

What will happen after smartphones? It's anyone's guess, and I'd say that whoever is going to invent that new device already has the idea and is trying to get it developed.
You rock, as always :)
love the interactive demos.

one fundamental thing i always feel is missing with all these videos and articles about the spinny circles set end to end with different phases and amplitude is: why on earth do such configurations happen to have the capacity to approximate any function you prescribe??
to me this is the entire mystery behind fourier transforms.
the spinny circles are kind of unusual to look at, but do nothing to illuminate to me why convergence of fourier series happens, and for this reason exactly i am of the opinion that this meme analogy is not useful for beginners beyond entertainment.

of course the details for convergence of fourier series are the entire topic of classical harmonic analysis. one hand-wavy way to make sense of it is to first sample and then identify that the dft matrix for the vector space of sampled signals is a basis. kind of similarly, int dx sin x sin nx from 0 to 2pi is 0 for all n, and the span of {sin nx,cos nx} is somehow dense in some function space. although that isn't really very illuminating since to the uninformed it amounts to a numerical coincidence. every single article of this sort that i have seen falls flat in this respect and i feel like this most interesting part has been obscured.
> If it seems irrational to us, it's because there are other cost factors we don't understand.

Since they are shielded from almost all liability by law (something like $150 million liability cap + $12.5 billion industry fund; plausible disasters could reach $1 trillion+ depending on winds), it seems like there would probably be even more shutdowns if they had to pay for real insurance.
This is a very routine reply around here to every new iPhone announcement. Would you perhaps be able to elaborate on the features or improvements you did want to see but didn't?

I mean I have an iPhone 8 and what I see are:

- An edge-to-edge screen

- Longer battery life

- Faster processors

- Improved cameras (don't care much myself but it is still improved)

- FaceID

- Updated Wifi and LTE technologies (not sure how much hype that is)

- More durable (apparently) and more water resistant (at least compared to my 8)

- Multiple wireless headphone support (not sure I need this either but it is still a feature others will use)

I don't need to upgrade for any of these things, which is probably a good thing in terms of e-waste, but it is still definitely a clear upgrade from my current phone.
Unrelated to the post but I interviewd with GitLab this year and want to give them a shoutout. The whole process was smooth and the people I dealt with were SUPER friendly, even after I withdrew my offer for another.

Since then, I've moved most of my personal projects over to GitLab and try to evangelise them whenever possible.
I mean, it probably wasn't in the right programming language and was missing one little feature the org thought it needed and hell.... how hard is a chat application, right?

Offline wallets have limited utility. Once you want to do anything at all with the money it becomes vulnerable.
Solar and wind power are variable. They can't deliver power at night or when there's no wind. So to make them viable as the main source of energy they need batteries, to store a surplus during peak hours that can be used up when production is low.

Nuclear energy doesn't have that problem, so it doesn't have such a need for batteries.
I have a Watch 4, and contrary to how battery expectations usually go, the life on it is actually really solid. I’ve gotten close to 2 days on it before. I often wear it overnight, then put it on charge when I first wake up, it’s usually close/if not fully charge by the time I head to work.

91X broadcasts out of Tijuana as well, I believe. Broadcasting stops at midnight for the Mexican national anthem before resuming.
Some people would charge at home, some would charge at work, some would charge while shopping. People that can't do it will be a minority. By the time majority is electric, 350kw+ charging stations will become a norm, so it will be pretty much the same as gas station.

This is golden. Grow responsibily. Don't overhire. Consider overhiring neglegent and treat it as such. Dissmiss managers responsible for neglegence, before or with overhires. This will also alleviate the costs of overhiring.
I’m curious, are you worried that if everyone in your position doesn’t share data there will never be research on your condition and therefore no cures or better treatments?

I worry that one tradeoff of more privacy and less trust is that researchers won’t get the information they need to produce cures and treatments. It’s a faustian bargain that people who are sick have to either risk having their information leak, or risk science ignoring their condition entirely.
Not really. It's what's marketed as "VPN service".

And a key point of VPN services is that they don't share the ISP-assigned IP addresses of their users with anyone else. And they don't retain any logs, which an adversary could obtain in one way or another. Indeed, the best ones run totally in RAM, and don't have writable storage.

Edit: Also, using "VPN" in that context is not at all deceptive. Enterprise VPNs not only provide secure access to private resources. They also provide secure (and yes, often controlled) access to the Internet generally. And that's just what VPN services do. Except, mostly, for the "controlled" aspect. Although some VPN services do feature blocking of malicious sites, malware downloads, etc. Some even block age-inappropriate content.
