Uber is definitely not perfect as a business but the taxi companies are horrible all over the place. If taxi companies would just enter the 21st century, I would maybe never use Uber but the thing is, they don't. We see a LOT of rivaling apps by/for the taxi companies or just by a regional company because they don't want to give their money to a US company, but most of them are absolutely awful. The ones I tried in Barcelona were unusable, unreliable and just generally crap (disclaimer; I did not try Cabify yet). There are many in many countries but most of them, especially if they are created by a cap company, let you enter all kinds of info only to get to a screen says 'when do you need your ride?' and you can pick 24 hous from now or more. What is that? The GPS/Map feature looks generally untested and not working or not even there.

Besides the apps, most cabs are far more crappy than the Uber cars. I feel unsafe in a lot of them even though the cab companies insist they conform better to safety regulations; in Thailand, China or Hong Kong, cabs are mostly such garbage; smelly, usually missing seat belts, horrible suspension, drivers rude and not very good. Why would you go with them if there is an alternative? (Having said that, Barcelona is a notable exception; the cabs I was in seemed new and clean and the drivers friendly; not so in Malaga, Madrid or Faro for instance).

Then there is pricing; in a lot of places cabs are slightly cheaper for short distances than Uber, but long distance... I have had quotes of 400 GBP for a cab (and multiple companies) vs < 100 GBP for Uber for long distance.

If they would up their game instead of just whine and long for the olden days, then I would use them instead of Uber, but I cannot see it happen soon.
Because we tend to remember the few times where they get it very wrong (which is always going to happen because of the chaotic nature of weather) and ignore the large percentage of the time when they're right.

That's every single adult in the United States checking the weather four times a day. A bit more than I would have expected…
I'm curious how you determined GoDaddy to be trustworthy. A quick search for "godaddy horror story" returns a long history of warnings about shady practices...

Apple would never restore services to any individual or small business like this.

Neither would Google.

This is bullshit and Google should've been forced to deal with their mistake.
This is exactly what I've been doing for a while. I check whether my ideas are SOLID and this have been enough so far. When I change something it only affects its immediate surroundings so things are easy to fix. If something breaks it doesn't cascade throughout the system. I also like to have interfaces for all non-trivial things so I can stub them when I test and provide multiple implementations for different use cases (strategy). With this I feel that I'm insanely productive.
Quote from the research:

He may have misqualified 11% or more of those domains.
There really is a blind spot in the app distribution mechanisms. There is no way to distribute your app only to a selected amount of "customer / partners".

Either you put it on the app store, and everybody can download it, or you use an enterprise certificate but you're now at the mercy of apple having a different definition of what you're allowed to do with it and what constitutes a "member of the company".
hence the phrase: right combination of technologies.
Yes I do understand that. I don't really see any real difference between the two though.
You miss the point completely. The real issue is how much heads up you get before you get destroyed. This heads up time is what regulated cold war and kept both sides in check.

Effectively, each shuttle launch gives Russians a little heart attack and the culmination is basically each orbit that goes over Russia because SST is supposed to have capability to alter the course, dip in the atmosphere, drop the bomb and go back into orbit and they only get about 2 minutes of warning at best.

This warning time is crucial because that's all you got to decide whether you are under attack or not. For ballistic missiles launched from enemy territory you get half an hour and it means a bunch of people can gather data and figure out if it's real or fluke and make informed decision. You can't make informed decision in 2 minutes and it is extremely dangerous because it does not give you any capability to verify anything or ask anybody.
Just ignore the fact they're not in the field of CS or mathematics. ;)
disclosure - I have a significant interest in Apple.

Apple should shake down Google and Facebook, it'd be a good thing if the tech companies made their competition personal.

Sure, since about £200 of your trip are paid for by venture capitalists they can afford to offer such rates.
Yep, also never had an issue with it in practice.
This is unintuitive: the laser makes air heat up and expand. This is how the acoustic waves are created. But this alome is not enough for audible sound. Higher amplitude is required. They get it by "piling up" a wavefront (in colloquial terms) by moving the laser exactly as fast as the wave is moving away. This heats up more air and the additional expansion adds to the already traveling wavefront.
> I find it way easier to use Uber than get Taxis mostly due to the app based "click and collect" model

mytaxi.com does just that.
Even more so in places like India one of my co-workers a few years back mentioned that his family back home had lost property to "gangsters".
> We see a LOT of rivaling apps by/for the taxi companies or just by a regional company because they don't want to give their money to a US company, but most of them are absolutely awful. The ones I tried in Barcelona were unusable, unreliable and just generally crap.

Have you tried mytaxi? It works in many cities all over Europe (including Barcelone) and in my experience works pretty well, including the GPS feature and getting a ride immediately.
https://en.wikipedia.org/wiki/Uber#Criticism

Main criticism seems to revolve around Uber trying to bypass regulations that regular taxi firms have to abide by, paying holiday and sick leave, or vetting their drivers etc.
I think the parent took the literal answer of “no” to be a bit terse, depends on how you read that example conversation. I doubt anyone is arguing it’s actually rude to refuse to provide a phone number, just to not be snarky when doing so.
Source?

Also what's the proof that private organizations are a better solution to the problem?

Just look at the US prison system.
That sounds great when you have the data available! It sounds like your software is thoroughly tested. If only where I currently work had that...
As a new JS developer, I found React to be very intuitive as opposed to Vue.js. I remember trying to scour through some mastodon frontend code and it looked much more complicated.

Of course this is anecdata so take it as you will.
I'm not in the US, but as I like spending my weekends doing outdoor activities I check weather forecasts during the week a lot to try and plan what I'm going to do and where. Four times a day doesn't seem that much to me - I'd imagine people who work outdoors and farmers have even more reason to check the weather frequently.

[NB I even check multiple sources of weather information: BBC, Windy and MWIS].

The goal of the government is not to make money.

That's why people suggest to let the government run the nuclear power plants. Unlike a for-profit corporation, governmental organizations have little incentive to save money for maintenance by cutting corners.
>what about at 2 seconds away @ 65 MPH?

65 MPH is about 30m/s, your average lidar should be good upto about 200 meters, which is about 6 seconds at 65 mph.

> Will it detect a de-accelerating car faster than a camera that can detect a brake light?

Now this is an interesting question. yes and no. A lidar will on its own will not give you object recognition. It will tell you that a reflective surface of size _n_ is directly in you proposed path, and that since last scan its got closer. From that you can make a very accurate obsticle map.

I don't think that running a car soely on Lidar is actually all that feasible or a clever idea. Not without a boat load of mapping and processing to create a machine readable semantic map first.

Having a camera array _as well as_ lidar is a very good idea, as it can provide blended information from the lidar to the semantic map being generated by the camera and radar. Your example of brake lights is good, as it provides a cue as to what is likely to happen.

It also means that the high latency of a visual processing system is less of a problem, as the model can be updated by the lidar. Camera picks up a car, the model attaches it to the pointcloud it thinks is the car from the lidar/radar. When the lidar/radar updates it can create a prediction of where the visual system should look.

> detecting perpendicular cars vs parked cars at that range?

You don't have to. lidar gives you a point cloud, those points can be roughly translated into hard surfaces. if a hard surface is in your path or predicted path, take action until it isn't. Dealing with pointclouds for object avoidance is much much more computationally simpler, than having to infer 3d from either structure from motion, stereo or both.

https://github.com/raulmur/ORB_SLAM2 if you look at this slam system, the pointcloud it generates is very sparse compared to a lidar: https://youtu.be/W3ELziPYn5k?t=13

But as I said before, you need other sensors to get other data/corroborate world model.

>lidar was quite sensitive to dust, rain, snow, and fog.

It is indeed, like any other sensor

> Will weather cause the lidar to decay in similar ways to human eyes?

Most lidars operate in the far infrared. so will handle decay differently. Depending on frequency it'll either be sensitive to moisture, or not at all.
Missed that, sorry. Maybe with a psychotic pill (like there's atypical antipsychotics)
> No, they aren't. Not in any way, shape, or form. Private companies don't have any obligation to continue showing anything. They don't have any such 'moral' obligations at all. They aren't going into libraries and purging books.

What if the libraries are privatized?

> An actual purge would be something like systemically recalling, redacting, and deleting any remaining records of art that involve Cosby. Saying this is 'our libraries being purged' is completely alarmist and untrue.

No. An actual purge would consist of removing the work from circulation and locking the remaining copies in a restricted section in the library (a giftschrank). What you describe sounds like it's inspired by the fictional total censorship regime shown in 1984 [1] than by nonfictional examples.

[1] Which was probably lie even in the context of that fictional world; I wouldn't be surprised if the Inner Party actually had accurate archives kept in a giftschrank.
But one company can deal with multiple domains.
I have had quotes of 400 GBP for a cab (and multiple companies) vs < 100 GBP for Uber for long distance.

Is this because the cost of the taxi includes milage for the return to a base location? Taxis have been doing this sort of thing for a long time, so they include all the costs in their pricing models. Uber is designed for short hops around a city where there are rides to pick up in lots of locations. I strongly suspect that means the cost of the Uber doesn't include anything for the return trip so the driver will just have to suck up that cost. If taking long trips in an Uber gets popular you'll either see the cost go up or you'll never get a driver to accept the ride.
:-)

Well back when I worked for BT they had quarterly sprints but this was for things like major changes to the entire system.
It is rational from a self-serving standpoint from the taxist point of reference. The rational is to hurt Uber and consumers and by doing so giving Taxis an advantage (ie, they can now reach you faster than a Uber).

It is a huge loss if you look at it from a societal welfare point of view.

As I get older I am getting increasingly annoyed by anything that requires me to keep up with some sort of schedule or it falls apart. I particularly loathe monthly events (especially bills and subscriptions), and even yearly tasks seem like they are coming faster and faster.

I'm starting to wish everything would be designed with unattended 10,000 year time scales in mind.
The most rated answer by Dan Shappir took me down to memory lane. Worth reading, a very good history lesson.
No matter how complex your scheme is, if IP address is the only input, it's a (mathematical) function of f: IP → hash. Since IP(v4) space is 32bit (in practice, slightly less), if you know the function f, you can trivially enumerate all inputs.

From security point of view, if you use a fixed (unrelated to input) salt, the attacker will have a harder time to discover the function f (unless you store the salt next to your IP hashes). But from privacy point of view, in relationship between me (user) and you (service provider), you are the attacker. And you know your function f. Hashing IPv4 addresses, salt or not, gives me no privacy protection, since you can trivially reverse the hash - just due to small domain size. With IPv6, this problem will resolve itself somewhat; till then, I'd prefer if you encrypted those IPs with keys that have finite and short life time, in a way that a third party could audit if need be.
And to enforce standards, you better win some elections, right ? And how are you going to win them ?
I check the Air Quality Index probably 20X per day where I am in Thailand (Chiang Mai). Guess Americans are just neurotic when it comes to the elements.

The problem isn't really bad choices, it's uninformed choices. People don't realize how little data is needed to extrapolate a lot.

Then you usually get the "facebook is turning on my microphone without asking me" people. They just can't fathom that the precision with which they get ads could be the result of anything else.

This number probably includes things like swiping to the leftmost home screen on your phone to see the weather widget at the top. When it's that easy you can often check the weather unintentionally.
Making Election Day a federal holiday, or at least moving Veteran's Day to be concurrent, would be a good move.

Removing the Electoral College would be a good move.

Increasing and broadening the base of the estate tax would be a good move.

Increasing the highest bracket of the income tax would be a good move.

This isn't intended to be political, those are very specific policy actions clearly designed to reduce the inequalities of power by a) giving citizens more power, and b) taking power from the rich, and particularly from the rich who believe there is profit in supressing the people.
I would say that what enabled this in Oslo and similar local apps was a (relatively) respectable taxi industry. Taxi drivers had to agree to be honest about pricing and practices to standardize on an app and there are still plenty of places where they're more interested in profiteering from bad practices than being honest competitors.

I used to spend time in the south of France for work and the taxi drivers there were awful rip-off artists. They'd try to scam tourists for over twice the standard price. We used other known taxi firms and Uber moved in to save the tourists. The taxi drivers went on strike and rioted but being honest would have been better.

Uber is a distributed & centralized taxi company with software that isn't overly complex to copy on a local level. It had first mover advantage but is very susceptible to local competition, especially when local laws come into play (even if they're not obvious anti-competition laws).

In the end the main aim should be the drivers earning a decent wage, which is something Uber hasn't always been good at.

The name "comic" is totally wrong. The french name "bande dessine" illustrates better what it's all about. Take Pyongang by Guy Deslisle for instance. Since no one is allowed to take photos in many places north Korera, he created a "comic" book instead.

Yes; and what a lot of people omit is that if you have the full copyright to a GPL'd piece of software (because you don't accept contributions without extra license/assignment), you can publish it to the app store.

Why do you think Wesnoth is on iOS?
This is definitely wrong. In multiple conversations with Uber drivers, they prefer the longer trips as it makes them more money. They are able to not take long trips if they prefer (although they don't know the exact destination before accepting a trip, they are told if it is long one), and choose to do so.
Yes, it shows how much control Apple has and I am happy about it.
Anecdotally, that's why I use PCs (on Linux and Windows depending on the context) and an iPhone. I want my computer to be an open system where I'm not dependent on a single company for either hardware or software.

But I want my phone to just work reliably. I actually don't want it to be a full-fledged computer.
Agreed. On the other hand, you can't make courts fully robotic. The absurdly large size of existing laws are the consequence of trying to make them more like computer code, and having to patch countless vulnerabilities and corner cases in the process. In general, writing good laws as computer code is an AI-complete problem. That's why all laws leave some space for human judgment.
As a developer, you should be able to run the tests that are relevant to your work manually. The CI is there to do the complete validation, and to help you. Not to be in your way.
I wonder if tin foil can block this :p
OT: I'm not familiar with the app store details (I develop on Android) but if an Enterprise Cert is the only way, that's embarrassingly poor and I hope they improve it soon for the sake of other devs.

It's trivially easy to have a closed Beta/Alpha channel on the Play Store and updates are handled like with any other app update.

On Topic: it was only a matter of time until Apple restored the cert but I am still glad they revoked it as a very clear and loud warning. This might all just be grand posturing but it's good to see the big shots get a very public warning
I think the social welfare math is more complicated than you suggest. The cab driver jobs saved may offset the inconvenience for example.

Certainly from a car-hailing-rider perspective the Uber wait is worse but social welfare is much more complex.
It's actually pretty fun. Most yoga teachers use Instagram to share their schedules, it's a lot more dynamic, flexible, and engaging than a website or a mailing list (which some of us still have).

Posts are used as blogging tools. Along with fancy pictures of our latest poses, we like to write about the philosophy of yoga.

We also use DMs to communicate, along with WhatsApp, and stories to share random yoga and not yoga moments.

Yogis aren't just a group of gurus hanging at the top of a mountain :) Obviously, there is a conversation within the community about the usage of social media and addiction thereof.
Well if that smaller company is banned for life it is their own doing.

Meritocracy is a big word.

Chess is a meritocracy. So is tennis and sales. Anyone can play. The best player wins.

Chess coaching is not. Better coaches might win more or get better gigs, but stuff other than coaching "merit" can play a big role.

But rather than getting stuck in a semantic argument... What the article means is that it's a relatively accessible field, on the way that software engineering is. The formal pathways are not as locked in.

A motivated and talented individual can bootstrap a career without formal education, qualification or approval.

All this is relative to, for example, civil engineering, law, medicine... There you'll need qualifications earned via established formal channels, gatekeepers and such.
