For specialty lenses of various kinds, some people find it makes sense. But in general, as you say, there are compromises in using adapters in terms of function, size, etc. and usually it makes more sense to sell the existing lens and buy a native one.
I am suspicious about this statement for the following reasons:

* Some ST patents [0] say they are doing time of flight but have actually came up with slight variation on reflected signal phase shift measurement (see reply by Animats).

* Seeing internal API functions like this [1] in APIs they provide for sensors of this family. Of course, this might be something else (e.g. phase shift of internal PLLs/whatever).

* The shortest time in which this sensor performs measurement is on the order of few tens of milliseconds, and the high accuracy modes take up to 100ms. True time-of-flight systems (e.g. [2]) should have the answer ready on the order of nanoseconds (for the distances this sensor works at) and I haven't yet seen designs where there is so significant post-processing of the data which could explain this latency.

Don't take me wrong, I've worked with VL6180X and VL53L0X (and look forward to work with VL53L1X), and these sensors are the best in this size but I'm just suspicious that they are directly measuring time for the signal to bounce back, but are instead inferring the time based on some other measurements.

Actually, this made me think that I probably have photodiodes with wide enough bandwidth laying around so I could check the transmitted signal on oscilloscope.

This blogger, 8 years ago, wrote an excellent blog post detailing his method for improving his English: http://askakorean.blogspot.com/2010/01/koreans-english-acqui...

Warning: it’s not an easy solution, just an effective one. The main idea is “memorize more” and “practice more”. Judging by his blog posts, it seems to work.
This is true, but you also must engage in a GDPR contract with Google Analytics. I believe they have recently added this as a feature somewhere.
Article 13, to my reading, provides no basis for requiring locality information or security policies. The retention declarations I’ve seen have been legal niceties that don’t answer the question in a way that makes it clear what the retention policy is.

I’m not suggesting that the letter won’t get a response. I’m suggesting there isn’t anything in it that would cause a large organization to send any different a response than if they got a letter written in crayon that said “gives us the GDPR data”.

In that way it’s not a “nightmare” letter. It’s the default thing you pay lawyers for.

It also matters if you’re catching a regional rail train (e.g. on the Metro-North or LIRR), which tend to run on time to the minute.
I use my chromebook with crouton all the time. This semester for example, I did embedded development with mbed-cli (uses gcc for arm) and emacs. I also wrote LaTeX both on overleaf and on my chromebook (many gigabytes). I live with few hundred megabytes left and I listen to online radio instead of having gigabytes of songs. I delete stuff that I don't use and everything is fine.
Because without intelligent computers, the world we've built for ourselves would just... stop working. They have brought us medical advancements not possible 20 years ago. So we would pull the plug and kill many people. Not only that, but countries are competing against countries with their technology. So if America pulls the plug, everyone else is far more advanced and you have lost your military and political power. There is no "pulling the plug" unless the world is willing to pull the plug and willing to deal with what amounts to another dark age-- in which case, technology such as we see today is likely to develop again.

This tech is almost inevitable. We are creator beings. We want to make something that matches our intelligence-- and we always have. We've made pantheons of Gods to match and overcome us, we've made these autonomous beings in the stories we tell and in the dolls we played with when we were kids. The problem is that we don't know what machine intelligence may do when we let it out in the world. If they can learn the tasks we want them to learn, can they then learn how to learn a task we didn't assign them to? What kind of task would that be? How would we control it?

There may be no controlling it. But if we started focusing on this problem right now we may be able to figure it out. Instead, most everyone in AI is working to pump out as many "smart" things as possible, trying to develop better learning algorithms, get AI to become as human as possible, trying to make machines that behave like us but better, without paying attention to the future costs.

Maybe for the first time in human history we can learn without making the mistake.
I don't buy it, many international cities have just as big and complex systems. Trains generally run on time in Paris, London, Tokyo, Seoul, Beijing. Seems just about everyone can do it except us. I think it's a valid question to ask, given that there's nothing exceptional about NYC compared to others in its "weight class".
Here in Paris, the rail & subway company instead of "personal injury on a track level", use "people accident". I'd say that most of the lines in Paris are the same.
ZINGO: Bingo Cards for Mark Zuckerberg's Testimony
Not reliably. International corporate ownership is very complex. And consider the following: Apple instructs one of its employees to quit and start a new company. That company files the patent and gets it approved for cheap. Apple buys the company the next day. It's very hard to create a system here that's not readily gameable.
It's amusing that you view 4 years of college as excessive when your profiles states you are a lawyer. This means that you yourself spent between 7 and 8 years working on a degree.

The nuance you’re missing here is that advertisers can only ask Facebook to show to such and such from high level categories. Gay Male 18-35, San Francisco, into dogs, for example. That’s it. Facebook will then bill that advertiser based on how many people see that ad.

The advertiser has no idea who you are or even if they got your attention to the ad they just paid for.
So... People shouldn't use drugs that work for them because the bacteria will develop drug resistance to the drugs which are already useless because you can't use them otherwise the bacteria will become resistant?
In fact, I think the author is underestimating the impact, right here: "Of course, making this change will have a dramatic impact on your revenue for single-visit traffic, because you basically have to design your ad model to work completely differently from how it works today."

No, it will basically make a newsmedia site unprofitable. I think it is the EU that has not fully thought this through. Most of the news industry is already sickly, financially, and they mostly have no model other than advertising (with a very few exceptions). The reason all this data got collected, was to try to make the advertising valuable enough that they could sell it. It may be that it never really worked, but it sure won't work without it. I think either the EU will backtrack on this once they see that Google and Facebook can easily force people to consent (because people consider those websites too valuable to do without), but most other advertising-supported media cannot; or they will see that the long-term impact of this is that it accelerates the current death spiral of newsmedia, as all ad spending goes to Google and Facebook and almost no one else.

I leave it as an open question as to whether this would be a good or bad thing.
I have a limiting rule, living in New York, to leave for meetings no later than 1 hour before the start time. It ensures I’m relaxed and on time. It gives me a moment to observe before the action begins. And it forces me to be more judicious about the number of meetings I book. (Granted, this only works since I can be productive on my phone while I wait.)
> Similarly, in formal logic "true" and "provable" are not equivalent.

This tells me you've totally misunderstood my comment. More simply, "true" and "true" are equivalent, and "provable" and "provable" are equivalent. But while "valid" and "valid" are equivalent in the other definition, "typed" and "typechecked" are not.
If that is true, and there is no way for Facebook to survive AND give users more control over what, how, and when their data is shared then they may actually be in trouble.
Also TLS SNI transmits the hostname in plaintext at the start of the TLS handshake.
When you are brainstorming with yourself, during your commute, shower or whatever, do it aloud and in English. This helped me think in English and increased the speed at which I was able to turn a thought into a proper sentence, bypassing translation.
To me (as a life long New Yorker) this is yet another sign of our decaying society - our crumbling empire. I've often wondered if the people of Rome understood that their empire was crumbling. Did they actually see the signs as it happened, or did it occur in such a way that the slow-motion decline wasn't sharply felt? The problems here aren't just the subways. The roads, the bridges and other infrastructure are also crumbling around us. The airports are a disaster of endless construction that never get completed and just add to the misery of travelers and the sense of overall decay. The LIRR is as bad or worse as the crumbling subway system. More New Yorkers are living paycheck to paycheck as the cost of housing, healthcare, insurance, and education soar far beyond what working people can afford. Our bloated bureaucracy continues to grow like a cancer, guided by the likes of the eminently corrupt Andrew Cuomo (and his allies in both political parties who serve the same moneyed interests), draining ever-more resources while providing ever-fewer critical services. Homelessness and poverty are increasing, while those at the very top of the economic pyramid are growing fabulously wealthy. Among this myriad of growing problems, we as a nation continue to ignore these issues and pour our limited resources into endless foreign wars and occupations. Unfortunately, dark days are ahead.

Google has been working on making Google Analytics GDPR compliant, but you must actively change some settings to pseudonymize collected data and also sign/accept a GDPR contract with them. Also you must make sure to not explicitly add any personal data to GA. For example avoid sending any user names, email addresses, ip addresses, or any form data to Google Analytics as part of event data.

I don't have an overview of all steps required but provided you do this then GA should still be allowed to be used without explicit user permission.

I spent whole days reading Tolkien outloud while sitting on the balcony. At the time I did not know the meaning of many of the words but knew how to pronounce them. I avoided reaching for the dictionary so as to not interrupt the flow of my speech.
Most annoying is that they rarely if ever post the notices of partial service shutdowns outside the fare gates.
>Are you shooting in raw and editing your photos?

Yep, I do the whole works. All of them in RAW, spending an hour or so editing in Lightroom (with favorite presets), have a flickr (like every other DSLR owner). But it stopped being fun after seeing that so many people do the same 'artistic' stuff, it doesn't feel like I'm doing something 'worthwhile' anymore. Now I just want to take photos and videos with friends. I find them more important.

I used to care about the right focus, shutter speed etc. But with a phone, if you use the portrait mode, you get something like f/1.5, and if you don't, you get something like f/18. So that almost takes care of the focus problem for a lot of cases.

When it comes to shutter speed, I use the high shutter speed when there are faster moving objects. That's a problem with a phone, but with enough photos taken quickly, one of them usually turns out good. People use low shutter speed only for long exposure shots like nightsky, waterflow, etc. which isn't a 'normal' photo.

Low light is one place I guess where a phone can't exactly do as well, but as I said, it just needs to be good enough, and not perfect.

About the battery of DSLR, often I don't take it out anymore, and between uses, the battery is so low that I have to charge it. So it leave it, and next time, its pretty much dead. Poor maintenance, but it again ties into if it is worth it.
It increases the cost and complexity of an ISP tracking you, which is a win within itself. Plus some services share public IPs or are behind a global cache (e.g. Cloudflare) making it harder to pinpoint exactly which endpoint you tried to access.

Is it perfect? No. It is better than yesterday? Yes.

I call these "micro-wins." One micro-win won't make a difference, but two, three, four, and so on eventually start to have an impact. And that's all we can hope for.

Even often cited VPNs just shift the problem downstream. Instead of your ISP monitoring you, the VPN provider themselves could, or if you host it yourself then your server/virtual server's ISP could. VPNs themselves are another "micro-win" but people often claim they're a complete bulletproof solution.
11 Games You Didn't Know About (But Should)
As somebody who got later into macbooks, and begrudingly had to admit they were objectively superior, here's what I'd like to know about a competitor.

1. Does the screen ever flicker?

2. Has a key ever come off?

3. Does it ever fail to sleep when you close the lid

4. Would you worry if you drop it from waste height 5 times (closed, but running, onto a hard-wood floor) ?

5. Have you had any driver problems, have you ever had to reinstall the OS?

6. Have you had it crash one you more than once every 3 months?

7. Have you had any glitches (audio dying, network problems, charging problems)

Saying no to all of these is my personal benchmark for my air. I haven't used PC laptops in a while now, so I'm genuinely curious if the higher-end competitors can compete on this reliability benchmark.
Same here, out entire dev shop is X1 Carbons on Linux.
Station supports battery swapping as well, initially we are supporting Genze and few other PMV manufacturer's removable battery packs.

Scooters used by Bird, Lime and Spin don't have removable battery packs.

JUMP and LimeBike don't have removable packs for their e-bikes.

FordGoBike and Scoot have removable battery pack fleet, similarly HOPR cylce is also moving towards battery packs.

Station can be stationary or moving (on demand), everything charges inside the station so we don't have to change the location frequently.

Our station technology will also enable other manufacturers to move towards swappable battery packs, as of now there isn't any infrastructure available that enables hassle free battery swapping. PopWheel is building that infrastructure, but the idea is to charge everything not just micro-mobility.

Decentralized Solar is also on our roadmap, we can be the new PG&E that develops application specific infrastructure to deliver energy on demand.

So, we should all be monitoring all legal changes for every Internet connected country? Is PRC's great firewall a good thing? Because that is where things like GDPR will push the rest of us. The easiest way to comply with this murky EU regulation is to block the EU... especially since we cannot deny service on a case-by-case basis.

Linux desktop is doing fine. But I prefer to avoid GTK when possible. It's years behind Qt. Some thing like Firefox are necessary though, but it's a pity it's stuck with GTK.
Certainly, but that was no doubt true before it became an immigrant community. First generation immigrants are more likely to have experienced a very different level of wealth earlier in their life, which makes one's attitude towards the possibility of losing it different than if you were born into that class and society and had always been there.

But, I could be wrong.
Everyone else syndicates and usually only controls a small market. HBO is only in a few countries, for example, and all of their content ends up accessible in other areas. You can buy all of it from iTunes!
I'm confused as to why anyone would strongly believe something like this without any tangible evidence. For one thing, there are hundreds of hardware hackers that look for things like this, so it seems like if it were an issue one of them would have found evidence of it. For another, China knows this and wouldn't want to risk their global reputation in trade for something (spying on average citizens) that would have very little payoff compared to the long-term economic damage it would do.

Besides, as another commentator pointed out, if you're going to be worried about a country spying on you, it should at least be your own country.

To be clear, I am only talking about the interpretation of the regulation, not my own considerations.

The article made it sound like IP addresses are always personal data. My point is that, if I run a website and keep generic nginx log files, is it really personable data with regards to my website?

Yes, the ISP can link that IP address back to a person, but if that person came to me as the website administrator and asked for all data held for that person, I would actually not be able to make the connection.
It certainly has been abused. But I think it’s throwing the baby with the bath water to some extent.

People won’t be immersed in something that doesn’t bring them value. Some products would make money from users by showing them ads, others would ask those users to pay. Both would want to create immersive experience in my opinion. I would even argue that less immersive experience (getting bored or distracted) leads to ad clicks. Whereas a service that charges wants to keep users truly engaged.
Then you connect to one and boom, isp knows who you connected to.

Plundering the funds meant for unsexy long-term projects to fund services well in excess of current tax revenue is extremely good politics. Liberals love sexy new infrastructure and services, conservatives love the relatively low taxes, no one really gives a shit how smoothly public transit will be working in 30 years.

I wonder when someone is going to take on the task of figuring out how to encrypt SNI
Not sure why you're getting downvoted actually.

Yes, this treatment can probably help some people, but it's probably also true that deploying this en masse would not be a great idea from a long-term ecological perspective.

Low-dose antibiotics are already widely used today in farm animals because it lets them gain weight more quickly ( = more profit for the farmer). And now the bacteria have spread out of farms and into the ER rooms and are killing people. Another form of socialized externalities.
These are valid points. Encrypted DNS stops your ISP from sniffing DNS requests, but does not directly stop them from seeing IP based traffic, and potentially deducing the domain name, if that IP address is from a suitably unique source. (Shared hosting might thwart this somewhat.)

The slightly bigger problem is HTTPS with SNI, which leaks the host header in plain text before establishing the connection. It's an unfortunate necessity as long as hosting providers need to use virtual hosts behind a shared IP address, but it's also one more potential snooping vector to deal with.
Why did the media have to discover this? Doesn't FB have all the data on what these third-party developers are doing?
I code myself. I've watched it. Pretty good learning platform (never had a look at a MOOC before): I am impressed (but I will take a look at other MOOCs mentioned in this discussion and I will certainly be less impressed very soon). Finished the first week. Right now, I find it a good introduction for someone who has no knowledge of code and statistics. IMHO, the main advantage would be that such a person may learn what coding and statistical reasoning looks like. The main disadvantage would be that this person think he has learned enough and keeps not trying to learn more about those topics. What an enlightening free week for the people: first look at "Do you trust this computer?", then attend this MOOC "Data8.1x"?
I would trust the Russian mob before I would trust Comcast
If I can make a connection between an IP address and a person, yes then it is personal data, no doubt.
I prefer the careful manual selection of the shooting parameters and lens of a DSLR over my iPhone much like I prefer driving a stick shift over an automatic.

Unfortunately for DSLRs for my purposes, the joy of shooting one is vastly outweighed by the inconvenience of transporting it.

Once ICEs are dramatically less convenient than electric vehicles, I suspect I’ll give up stick shift too. Hoping that day is a long way away.
