And I agree, the build quality is really nice - just wish they sold the screen protector during the kickstarter - I have the silicon protector and wifi dev board but my LCD screen is scuffed from carrying it around in my pocket.
Ask HN: Optical phase detection for detection/ranging replace Lidar?
No background in this field. Can optical phase detection (of a high-enough resolution) be used for detection/ranging in place of a more complex system like LIDAR? I.e. a good-enough 3D map can be generated using an array of phase detection pixels?
If anything, the smaller an organism, the more it can take advantage of Van der Waals force, static, bioelectromagnetics.
Slightly related to the article, I watched a jumping spider crawling on my bench jump off the edge and curve its trajectory to land on my stainless steel dishwasher which was to the right of its initial jumping arc - I wonder if it was able to use the hairs on its body to create a static response or even as control surfaces.
Rules of Acquisition
My experience is that dev's have...mixed feelings about it because it can get in the way of "actual work" but only a few of those dev's are as good and organised as they think they are. The rest it's like herding cats and without Jira or an equivalent they'd be churning out dogshit.
Swearing, when used properly, punctuates an otherwise boring corporate message.

I think it's a case of there being multiple truths, and depending where you sit on the food chain you'll sing one and not the others:
1. If you're a highly competent dev it gets in the way and wastes valuable time
2. If you're a project manager with thousands of moving parts and a diverse array of talent from almost useless to God-tier it can help keep things on track
3. If you're a rookie you can at least quantify and digest which tasks require your attention and not feel overwhelmed
4. By virtue of some common personality flaws you over-estimate how good you are, underestimate what you need to do, and work on the wrong task and still say it's a pile of shit despite it being exactly what you need
Who is and how do you define that? I'd say in some very important spaces they're leaders, such as performance per watt in the mobile CPU space.
> by 2040 will be viewed as Xerox came to be
If you mean PARC's transition from an innovator to the one trick pony Xerox of today I'd say the difference is Apple keeps delivering high quality products and services in an expansive set of markets - some in so much demand you can't even buy today if you have the money.
Those products are rarely if ever the first to market, but always highly competent and aspirational to own. Their consistency in achieving this approximately a decade after Job's death should be a good indicator that they have a robust research, design and marketing process that will keep them moving.
I'm sure detractors would put their money on marketing being the primary driver, while happily ignoring Apple's achievements in engineering market-leading SOC's.
So we're going into uni-body territory but with a faster, simpler process than milling/printing. If Apple is happy buying thousands of milling machines for laptops and phones, a chassis injection mould might be the process they'd need to break into the car space.

I'd give the McDonalds burger a go though - it's always interesting to see how far food tech can be pushed and how different it is from the real-deal. The key in my mind is synthetic collagen to give fake meat the bounce/snap/chew of real meat (FWIW I don't eat fake meat often, just interested in food tech in general).
Optus is terrible. It's worth paying a slight premium for Telstra 4G. I'm on a 45gb cell phone plan for AUD$60 and it works everywhere, even in tunnels or remote areas, with speeds that shame my Fibre To The Building connection (though not in latency). My work laptop uses Optus and regularly loses connection despite being in an inner city suburb and close to a cell tower.
With regards to the featured article, I'd say multiple factors are at play - Roman concrete has amazing properties and structures that used it combined with good quality-control (i.e. correct material ratios in the concrete) and good engineering survived.
The human elements, quality-control and design, are less interesting than a magical substance.
Or they can go down the Trojan Horse route and bolt one of their A-series chips as a co-processor to a board with an x86 CPU, begin the process of rewriting the OS and other assets in their control to run on ARM and provide some encouragement for dev's to make the switch over the next 4-5 years.
By having an ARM co-processor lightening the load running system assets they could balance the parts cost by using a previous generation x86 CPU.
They've already offloaded the System Management Controller, image signal processor, audio controller, and SSD controller to the T2 chip (64-bit ARMv8 A10 derivative: https://support.apple.com/en-us/HT208862) - the next step would be integrating T2 into a full blown CPU/SOC. Maybe T2 was the beginning of the Trojan Horse?
I'm friends with a homeless Australian Aboriginal lady and she chooses to remain homeless/jobless despite offers of help as it provides her with a level of control over her life (she had a violent past), but not for a second would I say all people in similar situations want the same thing.
The part that's hard to grasp by well-intentioned people is that you can't always help. Two truths, neither cancel out the other: [1] We need to invest in permanent shelters (i.e. homes) for the poor/homeless who want to pull themselves out from their misfortune and live a more normal life. [2] Homelessness is something we need to embrace by providing covered/sheltered well-lit public spaces where someone can set up a 0-day camp to safely rest without someone tapping them on the shoulder to ask if they're OK.
Two more truths: [1] Many homeless have mental health issues which, if treated, could help them live a better life. [2] Many homeless are mentally fine, in control, and your offers of help are somewhat patronising. They'd prefer a nice cold beer or bottle of red than your free pass to a hostel.
Nothing special. Cognitive dissonance is alive and well in the filthy-rich through to the dirt-poor. As we can see - your level of personal agency will be the determining factor in how much the world suffers from it.
Unfortunately we silo our processes in virtual-mental-machines at the expense of good ideas cross-pollinating terrible ones.
While entering my passwords into FF and exporting/importing bookmarks was a minor (and brief) annoyance, the utter joy of using a feature rich and secure browser with no ads made it worth the switch, even if I don't have keychain integration.
Give it a go, even just for a week.
