Virtual embodiment is a bit different from regular VR and much more intense. Sure, I imagine there will be people that get freaked out in regular VR since fake violence is literally what people think real violence actually IS now. The fact that the unreal depiction doesn't resemble actual violence in any way except on a vague conceptual basis is totally ignored by most people. Luckily, though, things like PTSD are rooted in direct physiological effects rather than cognitive ones, so it won't cause too many problems in the long run.

Virtual embodiment requires a separate camera in addition to the VR. What they do is have you don a VR helmet, and in that you see the environment around you - but actually it's the camera mounted on your face. Then, however, the perspective begins to move. Without you moving yourself, the view you see moves, turns around, and you can see yourself. At this point, you basically feel disembodied. But then the perspective is slowly moved, with your real body still in view, into a 'virtual avatar' of some sort. From that point, everything you see is from that avatars perspective, and as far as your brain is concerned, that IS your body.

They have used this to transfer the perspective of large, imposing men into the virtual bodies of small women, then they have large, imposing male VR characters come in and begin shouting at them. As they look down, they see their thin arms, their short stature, their lack of muscle, etc, and they get legitimately scared of the huge male figure confronting them. Tests afterward showed that the men who underwent this experiment (men who had previously been abusive to their partners) showed a marked improvement in their ability to recognize fear in the face of others, an impairment common to most abusers.

It's a fascinating topic, and one of the leading researchers using it, a Dr. Metzinger, has proposed that a VR Code of Ethics be considered. I don't personally think we really have the ability to competently form such a code since we're pretty early on and don't really know how things will affect people, but it is an issue that's being considered. Any time potential censorship of things like this is proposed, I always consider the case of actors in films and plays. They're already far more "immersed" and doing things more "interactively" than any technology is likely to enable us to do. They use real guns (loaded with blanks), shoot them at real people, see blood packs explode, see those real people they personally know crumple to the floor or wail in pain, etc... and they're fine.
It's 100% manual[1]; that "safety" you're quoting is not referring to memory safety.

New repeated edits detection sneak-peek
I would also consider Nokia (HMD global).

> near-stock

I have now got a Nokia 7+ which has "Android One" (very close to AOSP) and it has been a great piece of hardware which gets updates. I think HMD Global dealt brilliantly with the security issue that affected some phones.

I agree about Moto though, in the past I have bought four Moto phones (G1, G3, G3, G4 - two were presents) and I had zero hardware faults (although they all stopped getting updates far earlier than I like). A G3 and G4 are still in daily use. One G3 broke a screen (teenager), and I can't remember who I gave the G1 to when I upgraded.

Multiple previous experiences with Nexus line have left me disappointed, and so far the Pixel's have been too expensive for me to want to learn the same mistakes again.

Hopefully the 3a will be better!
What is included in that R&D category? If it is mainly just maintaining their infrastructure, then there isn't much research happening, and thus nothing to even hope for in terms of breakthroughs.
there's all sorts of cultural stuff here - 'prime-time' on the broadcast networks has traditionally been off by one hour from the coasts (local time) - presumably originally to reduce the satellite demands when broadcasts first went national
You didn't even mention the Closure library which was released and then practically abandoned. We invested so much into Closure where I worked, with the promise that this is what Google used internally, when suddenly Angular dropped out of Google and that sucked up all the oxygen in the room.
Project Horizon: The American Military Base on the Moon
You're witnessing long-overdue movements in the direction of the Intention Economy [1] (a riff on the Attention Economy). In fact, the base concepts are not new - it's how companies do their buying, using RFPs. Now that we have computers, why should people have to schlep over listings filled with irrelevant stuff?

But the real problem seems this tendency to use Facebook for everything, when it's really not the best option for anything. Better platforms can provide filtered options automatically, reducing the work for both parties. I really hope FB starts losing its grasp on the web.

IntelliCode: how AI helps bring the wisdom of your community to daily development work, and a sneak peek at a new capability to detect repeated edits...
I wonder if things like I/O are heading to the Intel "tick/tock" model where expectation of change has to push out to 2 or more cycles, because it turns out endless innovation is just not sustainable.

So a new gizmo in even years, and a cheaper model plus some interesting extras in odd years?
Yeah, it's tactics but in the same vein where he says his legs are 'fu&ked' and wants someone else to pull more and then outsprints them in the end. This is a quote from Fuglsang:
“From when he attacked, I was still the one who was putting in the most effort because he always said that he was fucked. But he did the same at Strade Bianche, and there he still got me, so that's the game – that's the tactic."
Israel's generally quite comfortable with making religious allusions in its weapons systems - for example, the next step up in range/speed from Iron Dome is called David's Sling, and there have been military operations named e.g. Pillar of Cloud and Nachshon. Usually when they do that, though, they're direct Biblical quotes.
If your meter broadcasts your household energy usage, you may be able to use a ~$20 SDR dongle hooked up to a Raspberry Pi to read the kWh of the whole house several times per minute.

There are some little tools that make this easy: https://github.com/bemasher/rtlamr

You'll need to do a little detective work to separate yours out from the neighbors' but it's not hard.

For my house, I can also read water usage and natural gas the same way by alternating through the relevant frequencies.
Unfortunately, crawling isn't a terribly effective way of evaluating breakage, as the crawler doesn't sign-in, and therefore doesn't attempt to federate sign-in across multiple sites. That's part of the reason that we're not shipping this change today, but proposing it as a (near-)future step.

To that end, we've implemented the change behind two flags (chrome://flags/#same-site-by-default-cookies and chrome://flags/#cookies-without-same-site-must-be-secure) so that we can work with developers to help them migrate cookies that need to be accessible cross-site to `SameSite=None; Secure`.

Ideally, we won't unintentionally break anything when we're confident enough to ship this change.
Really disappointed in you Google for not addressing fingerprinting much sooner.
But that hash is a regular, fast hash that takes like 1µs to compute right? Doesn't that get lost in network jitter? Wouldn't averaging the time it takes to run for(i=0;i<Math.pow(2,18);i++); over 10 runs be much more accurate? Or is this meant to spite the 0.01% of visitors that really try not to be tracked and have turned off javascript?
I just grabbed the first google result. I didn't notice anything suggesting HPS and LED energy usage was comparable.
One thing to keep in mind, you are currently in a ten year bull market, the longest running in history. There is a hell of a lot of inertia there, so I really would not be counting my chickens just quite yet.

I disagree. I think Ruby/Rails is a good example of this. They maximize on developer happiness but that doesn’t stop users from using a bloated rails app. Take a look at GitHub/GitLab as an example of a Rails app I guess?
Be disappointed all you want, but they're not really "addressing" fingerprinting. It is exceptionally difficult --- computer-science Hard difficult --- to prevent fingerprinting; all you can really do is break popular libraries people use today. It's an arms race, and a much harder arms race than exploit-hardened runtimes are.
Can we design an LED that isn't affected by typical city fluctuations and spikes?
Lack of adequate support for versioning your schema and in general bad support for anything versioning with RDBMS is one of the main dislikes I have for SQL. I find SQL to be a beautifully expressive language when you get the hang of it, but no RDBMS that I know of has been able to adequately tackle the versioning problem at both the schema and the script level. Everyone's schema evolves over time, why is it so difficult for the RDBMS to try to capture the idea of database evolutions? This is the single biggest selling point for me in ORM land, because with regular (read: non-SQL) code you have all the typical version control mechanisms to help you manage changes to the schema. It's still not ideal, but a lot better than trying to manage this kind of thing in any of the tools that mainstream RDBMS have.
It's not meant to be permanent.

We already introduced tarrifs, they didn't hurt the economy overall, on the contrary.

What i don't think is sustainable is the 4million americans who lost their jobs to china because of the wheeling and dealing of Wall Street and Washington.

It's worth it because if he succeeds getting better deals all Americans benefit and we stop chinas blatant abuse of things like their developing nation status and complete lack of defending IP rights and access to chinese market for most companies.

That's whats not sustainable.
Unemployment hasn’t been this low in 40 years. Those drivers are gonna get sucked right up into the economy lickety-split.
I think you're confusing having different goals from yours with incompetency.
It grew by 10x, but I doubt Lyft's infrastructure or day-to-day engineering costs have grown anywhere near that much. That said, I have no idea what Lyft could spend $600MM on researching.

I'm in total agreement with you. I've tried different ORMs in different languages and I am always disappointed in how lackluster they feel in comparison to the Django ORM.

There are several things that bother me about using Django, but because of the ORM and it's tight integration with the rest of the system I don't think there is a more productive environment for me.

That being said I'm not a great developer. As a business-minded person who codes out of necessity, I find the Django tooling to be the right way to work most of the time.

Not having to deal with migrations is a thing of beauty.
that specific business activity is 7 years of non-compliance on top of however many years they had no actual user privacy before their 2012 agreement.

That specific business activity is selling information to advertisers, which is their entire business model.

So scale the fine to make 10 years of selling ads irrationally risky? I'm okay with that.
This is absolutely wrong. Fines scale with revenue because they are supposed to deter behavior. If I get fined $1000 the change in my behavior is different from that of a minimum wage earner and a multibillion dollar company.

FB has egregiously harmed consumers and has engaged in behavior that is criminal. In no way should they be left off the hook.

Surely there is a balance between overly taxing and letting them get away without paying them?
> For this reason it is safest to break sodium lights under water [...]

This sounds like dangerous advice. Sodium reacts exothermically with water producing NaOH. In practice this means it will violently boil and splatter strongly alkaline lye around. (Source: this is how my high school chem prof lost some of his eyesight.)
And when properly spec’d, light temperature is remotely configurable on the fly. Not so with non LED bulbs.
You have a healthy attitude towards competition.
> What does a profitable Lyft/Uber look like?

Only city centres. Uber, at least, is healthily unit profitable in New York and San Francisco (the last time I checked). Given ARPU is growing at both companies, the boundaries within which they can be possible would conceivably grow.

$3.49 is great, nice find. Hopefully now that Espressif has unveiled their fork of LLVM you (as well as myself :P) will be able to use Rust on the ESP chips soon enough.
That's not logically implied by the parent's statement.
It's a little surprising that population density isn't mentioned as a major factor in this video. While it doesn't explain the overall cost or cost overruns, it is a major factor in whether rail makes economic sense.

Here's some key statistics:

* US lower 48 states: 40 people per square km (km2)

* California: 92 people/km2

* DC-Boston (this is hand-wavey a bit): 200+ people/km2

* France: 270 people/km2

* Japan: 330 people/km2

* China: 130 people/km2

* Eastern China: 250++ people/km2

Most of the Chinese high speed rail is in the Eastern part of the country where roughly 400M people live. That's more people than the entire US in a space about double the size of California. Likewise Japan's high-speed rail links Osaka and Tokyo which are among the most densely populated areas in the world. A high speed rail trip between SF and LA could be free and you still couldn't have a remotely full train leave every 10 minutes like you do in Japan.

The Amtrak lines that make the most sense are the shorter length ones that connect cities. The video sort of mentions this and that is in line with the Brookings Institution[1] findings. There's no coincidence that most of these lines operate in some of the most densely populated areas in the US[2] (So. California, Northeast). The goal of transit isn't strictly to turn a profit and highways don't turn a profit either. It has other goals like replacing car trips and alleviating congestion but all of these require people to actually ride. To get riders, trains need to operate where people are.

Long story short, there are some areas where high speed rail makes sense in the US but the US simply doesn't need as much high speed rail as China does.

Unemployment is low, but workforce participation is also low. There are plenty of people not working, and those who are aren't being much more than they were ten years ago, despite inflation.
When it comes to price and pure hardware, nothing beats chinese phones, but the premium you're paying goes into better software and support.

As long as you're getting quality sleep, yes. But if you have sleep apnea or another condition that is affecting quality of sleep, greater quantity might be required to feel rested.
I think there’s a middleground there that if you want to support these countries then there should be a framework for this (Flutter Lite?).. But if you want the complete feature set that is “bloated” but has good ux/ui support then that should be fine as well.
> Net loss for Q1 includes $894 million of stock-based compensation and related payroll tax expenses, primarily due to RSU expense recognition in connection with our initial public offering.

I could be reading this entirely wrong, but doesn't this suggest that the primary issue during this quarter was administrative and one-off costs that won't be recurring far into the future?
Google's apps on iOS are pretty decent, though, and you can always like those services to the built-in apps if you prefer those.
Facebook does make privacy meaningless... and avoiding Facebook increases your chances of keeping some privacy but it is not guaranteed.

Wow, if this works, this is basically the end of CSRF. Essentially: CSRF relies on an HTTP POST to VICTIM.COM triggered by HTML on EVIL.COM, and that request carrying cookies. Today, even though SameSite exists, the default --- SameSite=None --- maintains that longstanding status quo. But after the change, the Chrome default will be SameSite=Lax, and while EVIL.COM will still be able to trigger POSTs to VICTIM.COM, those requests will no longer carry cookies.

To get the cookies to work from EVIL.COM, VICTIM.COM's developers will have to explicitly set SameSite=None on their session cookies. Which nobody will do, because nobody sets SameSite at all today.

Better still: 99 out of 100 CSRF exploits (maybe 999 out of 1000) target endpoints for which SameSite=None isn't needed; they're cookies nobody ever uses cross-site to begin with. There are only limited cases where anyone needs the behavior to change, and those cases don't track the most sensitive cookies.

As a vulnerability researcher for whom exploitable bugs mostly exist to spark joy: good riddance to CSRF. It was a dumb bug class, and never, ever fun to exploit.

Self-driving cars would be the only thing that makes sense, but it is a longshot and spending 80% of your revenue on that seems nuts.
$600MM/yr @ $200k/yr == ~3000 engineers?
FB has largely colluded with major media outlets in determining who would be "real" news. It has given the stamp of approval to most large media corporations.

Which is nonsense, I don't want it screening things. I want my family pictures and my friends thoughts and I don't care where they come from.

I don’t think it’s necessary to lose or fail in your career. However, there’s also something to consider - if you always succeed at everything, are you really being challenged? There’s a difference between always succeeding because you’re in your comfort zone or working on problems that don’t stretch you. For some folks, that’s probably fine. Depending on your line of work, it may not be enough if you really want to grow. Just my 2 cents.
They also said that theoretically they should be able to generate one million times more wattage given improvements to the design. Sure, it'll be 25-50 times less efficient than solar power, but it's certainly something.

Maybe we could make double-sided solar panels: One for the daytime, one for the nighttime.

4 microwatts per square meter is pretty useless.

4 watts per square meter is a breakthrough.
Isn't it funny how when you ask for citations, the other person flips out and says do it yourself? Like, I have to spend my time figuring out if you actually did research or pulled something out of your ass? Sorry bro, got better things to do with my time than your work for you.
Agree. That's the approach I took with Norm (https://github.com/dieselpoint/norm). The general idea is that I just wanted to get rid of JDBC boilerplate and use plain Java objects, but not stop using SQL. Being lightweight is the key.
That's nice; ls was fast enough for my personal use more than twenty years ago.

I don't have that many more files to list today, just some vastly larger ones.

Speaking of twenty years ago, that's about when some of the most stubborn programmers had quit the habit of using shifts instead of multiplies, and embraced floating-point.

Operations burned $85mm in Q1 ‘19 versus $80mm last year. Given revenues grew 95%, that’s a step in the right direction.

Lyft have half a billion dollars in cash on hand, however, which will only last another 6 quarters at this rate. At its core, that balance between unit profitability, growth and access to cash is the game.
I agree estimates are never going to be 100% accurate but that doesn't mean there aren't better ways to estimate than just applying guesswork based on your current teams circumstance.

The entire dev team walks out, and yes this actually happens surprisingly often and could happen to you’re team tomorrow. Now, what happens to all your estimates?

Well clearly anything short term is now worthless. You can build a new team and use older effort estimates as a guide, but with different skill sets and a massive learning curve they in no way translate into FTE hours.

Effort estimates can survive those kind of transitions. But, time outside of a functional team is not meaningful.
As a Canadian living within walking distance of the project, this is the first I've heard of blackberry's involvement. There are some people in tech that are excited about the project, but the vast majority of locals are extremely cynical of Google's intentions and skeptical of their long term commitment. The entire city team was fired not long ago for... Not quite incompetence, but close enough.

The fact is Toronto doesn't need this sort of project to begin with. There's more construction going on here than anywhere in North America and developers are fighting to build more, while prices continue to climb anyways.
The purpose of taxes is to gather funds for public services.
