> Apple will liberally use an already-known VR technique that involves using eye-tracking to render objects in the user's periphery at a lower fidelity than what the user is focusing on.

Should be enough if they don't have to render that full view, but only what the retina is focusing on I would think.
Not sure if you were just abbreviating, but my understanding is that there's a "Rust" plugin for VS Code which is not the same as the rust-analyzer plugin, is nowhere near as good and yet shows up first in searches.
Judging any bleeding edge tech by its first prototype is not particularly useful. The point is not what Google Glass was, but what could've become with steady improvements.

VR cannot replace AR anytime soon due to some obvious safety issues. At the moment they are and will remain separate things IMO
It is a reasonably complicated Python script, so is a nice milestone of progress.
I'm glad this has been your experience.. my experience in cities is largely limited - Portland, LA, Seattle, NYC.

For me, I've encountered huge amounts of harassment in the first three cities. Oddly in NYC I didn't have a problem with it. In the first three, I've had problems in almost every neighborhood.

I honestly believe that somehow, your experience has been very different. I'm not sure why that is... perhaps you have a higher anxiety tolerance than I do. But I've been followed onto the train by a person speaking about shadows, and how he knows people who do "really bad things", situations like that, more than I can count.
It helps. The building code part especially makes a lot of sense. And also realizing that a crane would have to be involved once you get beyond individual sticks. Once you have a crane involved then you've got to get it on site, at which point you're already dealing with truck logistics.

Maybe I just like the idea of a truck rolling up with a flat-packed house, Ikea-style instructions, and a couple of 3 foot allen wrenches to put the whole thing together.
The one place where Scala really doesn't shine is ML. There's nothing even close to equivalent to PyTorch or Tensorflow.

Actually, languages with rich type systems in general seem to really struggle in this space.
I'm fine with this other than it's funded by taxpayer money. Robbing Peter for Paul no matter the outcome is still a crime. We already have enough police problems in this country, we don't need to put more non-violent people in jail if they don't want to participate in the system.

Instead, an alternative should be financial literacy so that people _want_ to do this organically. This sort of leadership is more likely to 'stick' and promote long term lasting effects rather than forced behavior under the threat of duress. It also removes any incentive for bad behavior by political parties "yeah, if you don't drive the right car, or get the right degree, or do xyz, we'll withhold access to your baby bond account"
Don't expect this to be a consumer focused VR headset. MR is for work, and this will be closer to a hololens usecase than a general purpose gaming system.
Why? You can be an apple fan and just not in the right bracket to afford the latest devices. I know plenty of people who love apple but they are still on iPhone 7 and 2015 macbook since they cannot afford anything newer. That's absolutely fine. It's like I love Omega watches but I can't afford a brand new one - so I have a vintage one instead since that was what I could afford.
1100km / c is 3.7ms. In free air, light speed is 50% faster. So long as the distance you are covering is more than 2200km, you'll overcome that. Of course, there's also the consideration that there can also be a lot of hops in terrestrial links and it's often very far from a straight line path.
Good post. Self-styled revolutionaries who are proud of themselves for torrenting consequence-free rub me the wrong way too.
The point about no deductibles isn't entirely true: if you are publicly insured, you have to pay 10€ for every day you spend in the hospital. There is a hard cap at 280€ per year, after that the insurance pays the 10€ per day. Also you don't have to pay it if you are underage, are on state-aid, or for a few other, rare reasons.
'This Whole Thing Has Numbed Me to Money': GameStop Investors After the Crash

It greatly depends on the techniques used for rendering. Current rendering engines are focusing on pixel perfection at every part of the screen as they don't know where you are looking. More and more games use a hybrid between path/raytraced effects and other shader effects that could benefit from knowing where the viewer is actually looking.
Especially raytracing can get huge speedups from sampling less rays: https://www.peterstefek.me/focused-render.html

Nvidia has researched in temporarally stable resoultion reduction at the edges (needed or you'll notice flickers in the blurring) as well as enhancing contrast which the eye is more sensitive to in the peripheral vision than sharp details.

Put a lot more research into this as well as proper support in the major 3D game engines and we have a winner.
Baltimore Has Officially Ended Its Creepy Spy Plane Program
I think the comment said he wanted an AR headset. Which is a bit different than VR.
If they actually did something like that, they could kiss their GCP, Google Docs, etc... contracts goodbye. Especially with government customers. They'd lose an entire country not just for search, but just about every other service they offer.
Impressive what can now be done with such precision with just a regular webcam. Previously special hardware like the Tobii eyetracker was required for this level of precision.
We live in a post big data world, few companies maintain datasets 10b rows+ for anything else a decent MPP database like Clickhouse.

Also beware - investing in technology that does not support standard SQL will create problems in the future, like MAPD - amazing database just there is no way to connect it to enterprise analytics software like Tableau.
You may be interested in https://immersedvr.com/. Some videos suggest that their coders use their VR workspace to code the app itself. Not exactly what you described of course :)
Aggressive conformists demand religious adherence to established institutions, because the institutions are a source of comfort to them. The parent poster comes off like an inquisitor silencing heretics, because that's exactly what he thinks he's doing.

I thought that article was going to be about the newer stuff like decorators, "async", and unchecked type hints. But no.

The Rust compiler is doing a reasonably good job on error messages. It's especially good at explaining that thing A being done here is incompatible with thing B way over there. It prints the source for both places, which is a rare feature.

A compiler that does global analysis can tell you more about what's wrong. Python, in its interpreter implementation, doesn't have the global info to tell you about global problems.
Just fyi, I'm about as far from a sheltered techie type as they come... since 18, I've lived in shared room situations with strangers on Craigslist for most of my life, often in the cheapest and most unsafe neighborhoods.

I actually have plenty of experience in the big city, it's not like I'm someone who comes from the rich burbs and then acts disgusted by the people around.

If anything, I've only become more bitter and hardened over time by living in the city. I was much more empathetic before it happened for 10 years+ and before I was put in so many unsafe situations.

Again, I'm not even referring to minority neighborhoods, actually most of these people are white (though certainly not all).
This has much to do with fading and such. If the polarization of the antenna sending is 90 degrees from the antenna receiving, for example, you will get no signal, even if close. This sort of thing can make the signal get weak as though it was 3x as far away at random as things move.
I'd argue it's just "languages that are not Python struggle in this space". Python has an undoubtably unique ecosystem and gravity around ML, but that's more a unique advantage of Python than a weakness of every other language design
Funny, every coach I ever had said "stick to the fundamentals". Probably just experience talking.
What is up with these app names? Enzyme? Tapenade?

I think part of the problem is the peripheral area where you wouldn't notice but still see is so thin that you don't save a lot. Maybe Apple has cracked it, though.
I agree with the sentiment, but it's also not helpful to lay blame equally. It's pretty obvious that the Republican party and their peripherals (fox news, et al) have caused way more damage than the Democrats.

(Not to say that the problems in our society can be distributed fully between those two groups).

Yeah - I don't love DG&E as a physical plant - I much prefer a very American-style one-story, big parking lot, urban sprawl kind of a datacenter ...

The issue is the he.net POP. We did use a fiber interconnect across Denver for several years to the coresite datacenter on (Denver) Pearl St. That was free because of a weird handshake deal we had from back in the day but when it stopped being free we really needed to go to DG&E to get 10gb links from Hurricane ...

I will also note that we partner with DenverOnline / Firstlink consulting which has their base inside DG&E so that also made good sense.

These are all business and personal relationships that go back to the mid-nineties and the Boulder bandwidth coop - we have a really great service and support infrastructure in Denver.
What language would you consider beginner-friendly?
In many cities, they are bused out to become someone else's problem.

I'm not sure what the solution is, but many of these people are obviously extremely unhappy, and they show no sign of changing soon.

If I viewed them as part of my community, it would probably be like pouring money into a black hole. Heroin tolerance goes up very quickly, and the associated costs go up just as quickly.
Self-Driving Safety and Systems
Tracking location by signal strength is highly error prone. Antenna orientation and multi-path can change signal strength a lot (+/- 6 dB easily) without the object actually moving. So the location data you get will be VERY approximate.
Look at the picture. The middle 'stick' of the three is just a bit longer.
Ask HN: How does Dosh make money?
Dosh is a rewards app. You submit your CC info, then somehow they tap into your transactions and pay something like 5% for dining at certain restaurants.

I noticed the app stopped working at one my favorite local spots after they switched POS systems. I stopped and talked to the owner, and he said much to my surprise he had never heard of the app.

I assumed previously that they were having the business owner pay them out, but that doesn't appear to be the case.

So what is their business model? I'm curious how the system works. Thank you!
Why was it painful? Learning JSX isn't that different from HTML.

If you're using React, and you're not using JSX you're gonna have a bad time. There is no option to work with plain html.
On the contrary, they didn’t know what to buy:

- an extruding, continuous freezer which clogged with mix-ins
- storage containers designed for milk which they destroyed by filling with ice cream mix
- square packaging which further complicates packaging
Why wouldn't you? The size of the community is definitely a significant advantage of Rust of OCaml, but if you want to use either then you need to be comfortable with reasonably niche things. Other than that, what is there? I don't believe multicore is relevant for the vast majority of projects (for instance those where JavaScript or Python could be plausibly used).

On the flip side, OCaml has a GC and Rust does not. For any other language and most usecases, that would be a dealbreaker. It's very cool how Rust has made it less so, but I'm not convinced it is magic enough to make it insignificant.
These military instructional videos are so great. They explain a lot of concepts very clearly. Nowadays videos seem to be more casual, with more focus on practice than understanding the theory.
> 5 years of cash flow

Physical sales are way, way, way down from 10 years ago already. It's only going to trend down further. I wouldn't call that a reliable source of cash flow.

They've already done that, Google's market share in government is approaching zero. They just aren't a B2B company, unlike Microsoft

Depends? Do you mean Uni comp-Sci classes, paid boot camps or what?
I suffered this a year ago and it sucked. But I scraped together help and advice and got it working and now it's just amazing and works perfectly with no maintenance. I'd love to pay it forward by working 1:1 with you to get yours working. I'm free any time during Toronto office hours if you'd like to take up the offer.

And of course if you want to keep using IntelliJ, that's an awesome tool as well.
Yea, tribal politics is so toxic and so incredibly entrenched in our government. There is no room for getting elected for someone who shuns parties in favor of saying that they decide for themselves on each and every issue and not what their tribe has already decided. I don't have the slightest clue about how to fight it or even make it slightly less bad.
And not a single director goes to jail. Not even for a weekend.
I meant that you wouldn't use a Church encoding workaround for a visitor pattern. (That's what you seemed to mean by "here's a way to encode them precisely.") Instead, you'd use the visitor pattern in the normal way. So the Church encoding workaround is useful in neither Haskell nor Java.

‘Holy grail’ nanoparticle injection that treats skin cancer developed by Yale
...Until it gets branded as a white supremacist tool for encrypted communications.

Call me extremely pessimistic but events like Jan 6. will be used as justification to start attacking applications that offer end-to-end encryption, and encryption in general. Just like 9/11 was used to justify eroding certain civil liberties.
You might have missed it, but they’ve publicised every year the advances in ResearchKit. It’s been around for 6 years now, and has influenced the design of several generations of watches. They have partnerships with various hospitals and universities, and severalstudies that were made based on data from Apple Watches.

You are disingenuous when you reduce the device to an accelerometer with a network chip. But even so, the problem with a lot of clinical studies is not the complex equipment required. Instead, it’s enrolment, and the fact that you have to go to a lab to perform tests and that nothing that happens outside these tests is measured. This could be gait, heartbeat, sleep patterns, or a lot of other things. The fact that people keep their Apple Watches on their wrist all the time, and that it’s easy to enrol and that there are significant data protection measures in places helps with the most complicated aspects of running a large-scale study.

I would suggest reading at least a Wikipedia article before spewing uninformed bullshit.
The future of AR is VR. With 8K screens you just redraw reality.
You are adding requirements and escape clauses to the federal charge of conspiracy that are not actually in the law. Here is the relevant text of 18 U.S. Code § 371:

> If two or more persons conspire either to commit any offense against the United States, or to defraud the United States, or any agency thereof in any manner or for any purpose, and one or more of such persons do any act to effect the object of the conspiracy, each shall be fined under this title or imprisoned not more than five years, or both.

The question, fundamentally, is whether or not what McKinsey did counts as to "effect the object of the conspiracy". If yes, there is no magic "go talk to your lawyer" phrase to escape criminal liability, for the same reason why you can't bring a lawyer with you and depend on attorney client confidentiality to protect you from search warrants and prosecution.
Laptop + magical AR/VR headset means you can always have your 3 monitor workspace, even at the coffee shop. Plus, you get fully private screens.
> Retaining talent is even more important than you might think. It’s crazy that in an industry where the main value is tied up so much to individual contributors, people change jobs every two years

For most companies I'm familiar with, switching jobs (usually to a different company) is the most effective (and often the only) path to achieving a significant raise or promotion without moving into management.
So News Showcase appears to be their end run around reality that they need to pay for news content they scrape with Search: They rolled it out with a plan to pay publishers to be a part of it, including the ability to use the content in Search, while claiming they are not actually paying for Search content.

But the biggest news is just that Australia called Google's bluff, and is going to pay up for the content they scrape.
Around the early/mid eighties, I got to play in a flight simulator for the new F1-11 avionics package Australia was buying (my dad ran the project building the sims).

It had a pair of Silicon Graphics Reality Engine IIs, one projecting a lower res image over the entire half-spherical screen, and the other driving a projector mounted on a gimbal that tracked the flight helmet - to display a high resolution image in the direct field of view of the pilot.

It was _possible_ if you tried, to "trick" the system so you could notice from the pilots seat what it was doing. But it was _remarkable_ the difference between sitting in the seat with the helmet on, and watching from behind where you could really obviously see the high res patch of sky moving around. Enemy planes turned from Space Invaders kind of pixel art into recognisable Russian fighter planes when the pilot looked at them. The "immersive reality" while flying the sim was amazing.
> low energy input (direct sunlight)

Direct sunlight is actually quite powerful, around 1kW/m^2 at sea level.

Although I'd guess most trees aren't particularly efficient at absorbing CO2 vs the energy they consume, which makes sense, since they only have to be as efficient as necessary to survive.
This is awesome! As fan of Rust and Python as I am I can't be more excited for this... great work everyone!!!
It's nonsense that happens to not raise an exception.

Typical use would look more like this:

x: list[int] = []

i.e. x is a list of integers that starts out empty.

It doesn't automatically do anything at runtime, it's basically a glorified comment for tools and libraries to use. So that does make it harder to figure out what it is.
Based on the article and some guesses, potential advantages to swappable batteries might be: weight (as you mention); cheaper/more environmentally friendly materials; lower risk of spontaneous combustion; less dangerous stuff leaking out when the unit is breached.
The Cadets at New Market
I was at a startup that ran for two years and wrote a lot of code.

At the liquidation, the entire body of code from the two years was auctioned for $1372 to one of the founders. Chances are, if he had not bid, it would have been abandoned entirely. I doubt he looked at it, after.
Python is great glue. But it's huge. Packed full of features. Has all sorts of syntactic sugar. It's the C++ of scripting languages. Great for an intermediate programmer who just needs to slap something together. But at the very beginning, these can actually be drawbacks because there's so very much to learn.

I would suggest something small, that you can realistically fit all in your head. I honestly believe Pascal is still an excellent choice. For something a little less low-level and more scripting-like, Lua seems nice. The JavaScript ecosystem is awkward, and there are things to criticize (no integers?) but by itself, it's a nice small language as well.
I write technical docs in Asciidoc format using AsciidocFX, I use Asciidoctor to convert to HTML, and Asciidoctor PDF to convert to PDF - It's a workflow I'm really happy with.
> The Apple TV has HDMI out—who knows where that signal is going!

Sure. You could also point your webcam at your TV and then malware on your computer streams that to the public. This is all just a matter of how likely each problem is in practice.

Lua was the first language i learned where i actually started to 'get' programming. I'd tried python and a bunch of other languages before that, but lua was simple and barebones enough i could focus on learning how to program instead of how the language worked.

When i tried to learn python i got caught up in trying to learn imports and classes and other things before i actually fully understood how stuff like variables, arrays and functions worked.
It sounds like the projections were caught up by reality. They spent too much, expecting the new shops to be as good as the old ones.

It's like if my mom and dad had decided to mass produce spring rolls. My mom actually made about 100K of them over 30 years, manually. If they'd built a factory, it would be a totally different thing. In fact, another immigrant did just this and his product is still for sale in supermarkets.

As an armchair CEO, why not just license? What you've produced with Oprah and Disney is not an amazing ice cream, you've made attention. By some stroke of luck, too. Chances are, ice cream being a rather ordinary thing, that your ice cream is ordinary and appeals to people about as much as an ordinary ice cream does. But you have that Disney tie-in, and you have celebrity attention. Why not turn your business into an Instagram marketing thing, go around chasing celebs, and let other people make the stuff, which they probably can scale better than you?
Is this only for Google traffic?
Thank you for the feedback. I was conscientious of that shadowing issue when writing it, but I just wasn't sure what to change on either side to differentiate them.
