> Nothing, but they'll be wanting HoloLens-class devices to be running Windows. This thing runs Android.

The article states that Lenovo doesn't have strong opinions about which OS the hardware runs, so it sounds like Lenovo has hedged to also support Windows on the hardware when the time comes that Windows on ARM is out of Beta (around the time that the HoloLens 2 releases?). Microsoft will still have a play to convince people to buy the Lenovo hardware and run Windows on it, the hardware sounds classed to be capable of it, and that's probably a good competition for all involved.
If you want a shorter workweek you should definitely sign up for the 30 Hour Jobs list (https://30hourjobs.com/), but—keep in mind there just aren't that many companies that have advertised positions that qualify.

Which doesn't mean you should give up. What you can do as a programmer is _negotiate_ a shorter workweek. I've done it at multiple jobs, personally.

Here's one programmer I talked who has been working 4 day a week for 15 years: https://codewithoutrules.com/2018/01/08/part-time-programmer...

And if you want to do it yourself, the easiest place to do it is at your current job: https://codewithoutrules.com/2019/01/25/4-day-workweek-easy-...

(And for those who will chime in explaining how no company will ever agree to this, here are some more examples of people who have done it: https://codewithoutrules.com/2019/05/09/part-time-software-d...)
I don't know about everyone but I just looked and was shocked to learn 42% of Americans have passports, 10X the level 25 years ago.

Personally I rarely carry any ID at all, and when I do it's a non-"real ID" driver's license, which I have though I don't own a car. Almost anywhere where ID is "required" (including air travel) it turns out that if you don't have any you can still do what you want (note I'm old enough that I don't get carded for alcohol). I generally have ID with me only if I know in advance I'm going somewhere where I cannot do without it, a couple of times a month. I fly more than that!

(It's absurd that a driving licenses are also IDs, but that's another discussion).
No not under market rate, if your goal is to work 30 to 35 hours a week under market rate all power to you but if you expect to be getting paid $400k total compensation or more you better be giving me at least 40 hours of work that i expect from a senior engineer. 5 to 10 hours is a full day of work.
Everyone? I've had once since birth, but it's foolish to think "Everyone already has a passport". As of 2018, only a ~1/3 of US citizens (137,588,631) have an active passport: https://travel.state.gov/content/travel/en/passports/after/p...
Or maybe that is just what level 2 would be? Level 1 is doing cost-benefit analysis on all problems. Level 2 might be doing cheap meta analysis to determine if energy can be saved and a level 0 solution used, or if more thinking is required. I would think there is a top level, which is full memorization of the space in which thinking might occur. Than instead of any thinking taking place, a reference is made to this memory-truth-table and the correct action is produced in response. Such a truth-table sounds maybe a bit paradoxical though. Does it take into account its own presence in the situation?
I'm not an expert and I'm not that interested in arguing specific numbers - I have no emotional attachment to them. The article being discussed here disputes your claim.

A recent study estimates that more than a quarter of all that waste could be pouring in from just 10 rivers [...] The 10 rivers that carry 93 percent of that trash [...], so 10 rivers are said to contribute 25% of total trash and 93% of river-trash. That'd leave ~68% from the shore, which sounds very high.

I feel "abstraction" (as a term) is thrown around a lot, but should only apply to the conceptual system (aka, while in the computer science realm).

Once you're dealing w/ the implementation and it turns into something concrete (aka the engineering realm), it's just a layer of indirection (and it serves its purpose by reducing coupling), but you still have to consider that underneath all you're talking to some machine, over the network, there's latency, it can timeout, there could be a load balance in between, the cache may not be coherent for consecutive requests, you assume some operation is both atomic and produces instantaneous side-effects, and so on... if you ignore these details you end up w/ a system that looks great at a conceptual level but is full of problems and race conditions because you ignored physics.

TL;DR "Leaky abstraction" is pretty much a tautology if you look up the meaning of "abstraction"?
I live in sunny California but I still have problems with not enough sun. I used to be a cyclist and triathlete, being outside for many hours a week, and now I am doing maninly dancing. I am inside way more than I used to be. I can feel when I need more sun. Incedentally, I also had a recent physical where they measured that I had a vitamin D deficiency.

They said a lot of interesting things in this article related to the sun, so I leared some new things. At the same time I am surprised about some things they did not say.

I'm not an authority on the bodies need for sun, but I will give my non-scientifci observations. If some one finds this interesting they should do some additional research on the topic before they do anything I did, rather than just trust what I write here.

One thing that really interested me was an article I saw here on Hacker News a several months ago. It said it is well known people with higher vitamin D levels had some health bvenefits. However, one particular study found that giving vitiamin D supplements did not seem to give the same health benefits. The authors concluded from their results that people who have high vitamin D often get this from the sun, and the sun gives them a different result from just taking vitamin D supplements.

I tried going to a sun tanning salon and found that did make me feel a subtle "high", as if I had been out on a sunny day. (Your experience may very.) From what I understand it is UVB that is responsible for this, the "bad" UV. It is considered bad because your body does not shield against it and it does not cause you to tan.

General tanning salons want to give you UVA. The expensive machines limit your UVB exposure, and the cheaper ones give you more UVB (salons often have different options for beds). You want to go to the cheaper option. I used beds at tswo salons with 5% and 6% UVB, for reference. They should know the UVA/B statistics for the machines.

As far as length of time, you don't need to go that long. The point is not to get a tan necessarily. I found that i would get more tired if I stayed in too long, so there is sort of an optimal time, for me at least. (I am very pale, by the way.)

I also noticed that the sun tanning bed was not enough. It is almost as if there are two effects. I feel good from the tanning salon, but at the same time it feels like there is something missing. I also need to go outside, I assume to get visible light.

To repeat above, these are not scientific results. I find this seems to work for me, and that is good enough. I would not suggest someone trust what I say here as authoritative, but hopefully it can be an inspiration to look into this if you have similar problems.

FYI, one thing I want to look into as a result of this article is timing of getting visible light. I do know that if I wake up in pitch black I have trouble getting out of bed. I would link to get more bright light in the morning right when I wake up and see how that effects me.
> Giving money costs money. Letting people use a bus that was running anyway does not.

That bus isn't running anyway though. It's (at least partially) paid for by ticket sales, you'll have to offset that by increasing the government subsidies to 100%, which costs money.

Big tech companies still use very valuable process, usually high amounts of tech (some in house but there is a lot to learn from even that).

The prestige is that they are hard to get into so if you made it you passed their bar and you probably had some impact there and learned good process that you can bring to a usually less disciplined startup.
I find that my productivity, when I am specifically constrained to 30 or 35 hours a week, doesn't really change--because it puts a clear value on my time to other people.

Or, put more simply: I end up in way fewer meetings.

Not an option for everyone obviously but it's actually not a bad idea. I got an "extra large" rural mailbox a few years back and it's been great. Not everything fits of course but most basic book and small to medium parcels do. It also means I don't need to get my mail held even if I'm out of town for 10 days or so. My postal carrier even thanked me for getting it at one point.
It is not, because it is not the same execution model that is being compared, it is apples vs pears.

If I instead stay at my desk consistently, my week is over by Friday morning.
Of course I used the comments on PhDs to tease my friend. In reality, this article, and my friend (advancing use of VR, etc in education) are two great examples of using technology to discover and spread knowledge. Of course, network effects/diffusion are critical for the spread of knowledge. In both cases, by using accessible technology and by making knowledge digestible/approachable, you can increase the transmission rates.

This article takes a complex set of ideas and presents them by using appropriate symbols, building a base of knowledge, and then adding to it incrementally. I thoroughly enjoyed it, and I hope many of you take the time to enjoy it as well.

(One final thought - one of my early JavaScript projects a couple decades ago was to write a simulation like this using Conway's Game of Life and some GIF files I created in MS Paint of red/blue dots, two types of trees, or the front/back of pigs. So there's some nostalgia boosting my enjoyment here!)
If we are only allocating 10,000 acres a decade for land lost to power generation then solar is a non-starter. Solar Star is a 579-megawatt (MWAC) photovoltaic power station spread over 3,200 acres. For comparison Fukushima Daini was delivering 4400MW.
For an individual no, but with enough data points, which probably exist since roundup exists long enough, you could make a reliable prediction where it came from.
That seems like hyperbole to me. Remember, we live in a republican democracy. Yes, it works slowly (by design). But, it works. At least we don’t have a totalitarian state to deal with.

I used to be skeptical of this stuff, too. Then, we had 18 years of no major terrorist attacks.

The idea always existed in the space of possible ideas. The military-backed researchers just found it first.

Probing their ethics? Have you worked for any large corporations? They all do unethical stuff. It all depends on your views specifically.

I find copyright and patents to be unethical. Probably not many people I could hire if I employed a similar tactic.

Wow, what's the procedure like for when you don't have your ID if you don't mind me asking? What do you tell them when they ask why, how do they verify you, how early do you come/long does it take, etc.?
I wouldn't be surprised here if Microsoft was even intentionally lending the IP. Microsoft doesn't want to be the sole hardware vendor in a category, so encouraging HoloLens clones is probably somewhere on their explicit agenda.

You realize that a vanishingly tiny slice of developers make $400K a year, yes? Yeah, sure, a few companies pay that kind of money to a subset of their people. Nobody else does.

And that's fine. I'd have a hard time not sawing off a hand before working at three and maybe four of the "FAANG" group. And I like having a life, so I'll leave money on the table all day long.

Do you have an email / contact info I could reach out to?
In the current presidential administration, this has become a very good idea, to carry around excessive proof that you belong in this country....
You feel that way because it does not move the needle for someone to use your own product on such a small scale. Now let's say that same employee was socializing or coming in contact in some way with a decision maker for a potential large customer (or a current large customer). In that case you wouldn't feel the same way. And if you did feel the same way that wouldn't make much business sense because you know business and making a profit is important to most companies or should be. So sure it's easy to take that attitude because you think it doesn't matter (in this case) or because you aren't considering the very general sense of what it might mean to others.

It's is well known that companies go to great lengths for various reasons to encourage their employees to not only use their own products but to discount those products for an employee. As far as you paying for Cloudflare so you can see the end to end experience that's fine and that makes sense. However Cloudflare should consider reimbursing the nominal amount that you are paying. Further they should consider (Apple and Adobe did this as well as auto manufacturers) giving discounts to 'friends and family' because it's a decent source of feedback on the product. You know what else it does? It encourages friends and family to support the person continuing working for the company (because it's in their best interest because they get a benefit). I know of someone personally whose brother is high up at a well know auto manufacturer and the brother gets a car literally at no cost just to be an ambassador and encourage other sales at that company (and it works I have looked into buying the car as a result as have others).

Permanent residents (and non residents) already get their prints scanned at every entry. I'm a naturalized citizen now but was always mildly bothered by being singled out (my wife and kids are US citizens by birth) for that level of screening.
The Country That Exiled McKinsey
> We have enough land in most part of the world that if we lost, say, 10,000 - 100,000 acres a decade due to meltdown, we'd still be pretty okay

This is completely untenable. Perhaps you're okay with it if it occurs far from where you live, thus not affecting you, but it sure does affect other people. And the surrounding areas. It's not comparable at all with the other forms of energy production in that list aside from fossil fuels which are an even worse danger.

> we know how to engineer around systems failures.

We don't really know how to fix human-related errors, such as hubris, pride, laziness, shame, and so on. So many things are completely obvious in hindsight, but we continue to make similar mistakes now.

I travel with work a lot. Seems normal to carry some ID like a passport when travelling, to me.

Hotels often ask for ID. You don’t know if your plans will change and you’ll need to fly straight to another country, etc.
I did this every time I re-entered the US for several years. After a few times, they took to arresting me for 4-10 hours on EVERY ENTRY, sending busses without me, making me miss connecting flights, et c. One time I was locked in a room without food, water, or medication for 12 hours. (FWIW, I'm white, a US citizen, employed, and wealthy-by-most-standards-but-not-by-HNs.)

They'd sometimes simply intimidate me, sometimes they'd make a big show about searching everything I had (not even looking in every zipper pocket), et c. In all cases they would lie to me and tell me what I was doing was illegal. (Remember: making false statements to federal agents is a crime.)

I eventually stopped after a few years and would voluntarily yield to their probing questions to avoid delays; I continued to get harassed by border guards and sent to secondary (for an additional 1-10 hours of arrest) on every entry for approximately 4 years afterward, even when answering all questions in full voluntarily. These days, they don't ask me questions, and just wave me through. I'm curious what changed a year or two ago to make them stop harassing me for exercising my rights for 24 months some time ago.

Oh, I almost forgot: one time, they digitally penetrated a Canadian woman who was my travel companion, simply because, in secondary (where we ended up because of my previous rights assertions) we both declined to unlock our phones for the border cops. They strip searched us both, and denied her entry. Denying entry is somewhat understandable due to the failure to search her encrypted device (if a bit dumb), however, sexually assaulting her and forcing us both to manipulation of our genitals is a little bit beyond their mission, in my opinion.
How about focusing on public works so at least we get some contractually obligated public infrastructure out of the stimulus.

Architecting a scalable Graphite metrics deployment
I believe nuclear power is inevitable. Human power consumption has been growing exponentially, at some point renewable energy will not be able to catch up without causing extensive damage to our ecological system. There are finite amount of renewable energy per sqkm on earth, at some point the area required will begin to erode local ecology. Right now nuclear power appears to be the densest form of energy generation. I agree in the short term renewable energy is a great alternative to coal/natural gas.
One of the problems with the “defend science” movement is that it’s often being (mis)-used to support philosophical positions that are fundamentally unanswerable by science: concepts like afterlife, gender, and when life begins. I’m not saying I disagree with the popular viewpoints, but science is the wrong tool for the job. (Does human life have inherent value? I don’t know, but better predictive models and more experimentation isn’t going to answer that question.)
A rational company would, but in practice lots of companies either don't know how to measure productivity, or they are confused enough to believe that long hours will result in more output.

So as an employee you want to ensure you have a hard limit on how many hours you're expected to work (40 for regular jobs, or as in this case, less than that).
> most modern compiled languages you can add strings and get a string, but strings are in fact immutable and can't be added without making an entirely new string and disposing of the original two.

In my mind, I add two strings like so:

https://gist.github.com/seisvelas/c11d200d0040a3686e47af0068...

That is, I realloc the first string to fit the second inside of it, then add the second string into the new space. But I have no idea what I'm doing. I'm posting this comment so someone can explain to me why my way is bad and why I should be creating a new string to put the others inside (which apparently is what everyone else does!)
More fully quoting him might be helpful "“From my standpoint, the driver of this is the business tax reform… if we get investment going, we get productivity going, we get wage gain going, we invest another billion dollars. Every billion dollars AT&T invests is 7,000 hard hat jobs. These are not entry-level jobs. These are 7,000 jobs of people putting fiber in ground, hard hat jobs that make $70,000 to $80,000 per year,” Stephenson said at an event hosted by The Economic Club of New York on Wednesday."

Indeed. Whenever a commercial is on, I like to ask the kids "What is this ad trying to sell you?"
> I can't help but suspect that these ad-free kids need to be exposed to some advertising in an educational context so that they learn to recognize when somebody is trying to con them into buying shit they don't need and probably didn't want in the first place.

Do you mean something like, the Internet?

Advertising is so pervasive, you'd probably have to do something drastic like Amish style technology banning to avoid it; even that may not be enough.

As a side note, even though Netflix doesn't have separate advertising, I'm sure there's at least product placement and other forms of advertising in their content.
A better formulation:
Abstractions do not adequately describe the full working of a system. So higher-level approaches will always require a knowledge of lower-level operations.

However, the opposing and terribly named "Dependency Inversion Principle" is true much more often: "High level [approaches] should not be dependent on low-level implementations."
It's TV and movies. There's no reason to regulate the production of creative content. Just do something else with your time.
