In France, speed of e-mobility devices is limited to 25 km/h on the streets and 6 km/h on the walk paths.

https://www.service-public.fr/particuliers/vosdroits/F308

Electrically powered vehicles (scooters, hoverboards, gyropods, monowheels) must use the bike path when it exists. Bicycles must travel on the roadway or on the bike path (if there is one).

The user must ride on the bike paths. If there are no bicycle lanes, the user may ride :

- on roads with a speed limit of 50 km/h,
- on pedestrian areas, provided that they ride at a moderate speed (6 km/h) and do not obstruct pedestrians.
Sidewalks may not be used unless authorized by the Mayor. In this case, the user must ride at a moderate speed (6 km/h) and not interfere with pedestrians.

Parking on sidewalks is permitted, provided it does not interfere with pedestrians. However, the mayor may decide to prohibit it.

Use is also permitted on private roads (e.g., private property road, driveway of a private residence).

The user must be at least 12 years old and must not exceed a maximum speed of 25 km/h. The vehicle cannot carry more than one person at a time.

The driver must wear retro-reflective equipment when

- traffic at night
- or insufficient visibility during the day.

As of July 1, 2020, your vehicle must be equipped with a braking system, a horn, lights (front and rear) and rear and side reflectors.

> Not only do you build internal software faster, you build more of it!

The problem isn't building too little software, it's building the right thing, making it robust, and making it usable all the while the requirements change to reflect reality and the underlying team shifts around over time. Simply building more software faster will give you more tech debt than you could've ever dreamed of.
There's a lot of misleading information flying around about how much the app costs.

The budget for the overall NHS Test and Trace system was £37bn last time I checked, and lots of news outlets seem to be trying to conflate that budget with either the cost of the tracing system (which didn't work very well) or the cost of the app. In reality, the vast majority of the spend has been on testing, and some of that budget likely remains unspent.
Not sure how another standard would make it better. But sure maybe something that used dash as a backend. It does seems like it really would suck to actually use, if my little experience with Javascript eco system is anything to go on. So different perspectives maybe?
Dumb question: Couldn't you build a roof from plain old solar panels, somehow sealed together? Put them next to each other with sealant in between horizontally, shingled vertically (this also allows you to have a drainage hole in the bottom of each panel if needed).

Besides the points all the other commenters made, there is an issue of congestion.

Trains and train tracks in the UK are _massively_ over-capacity. The West Coast Main Line, which is the main connection point between London and most of the Midlands and the North is the most congested train track in Europe.

Trains in the UK are expensive because we are decades behind in rail infrastructure spending while airports were targets of massive spending thanks to the boom in international low-cost flights in the 2000s and 2010s. HS2 should make train prices slightly more palpable, and hopefully more projects will follow.

Also, advance open-return tickets bought 24h in advance are massively cheaper than tickets last-minute tickets.

Hmm. In the Apollo 13 movie, high CO2 levels triggered a panic/anxiety attack in one of the astronauts. (Which may not have happened, or not as severely, in reality – but that’s adifferent issue. For one, astronauts are trained not to panic.) A quick google seems to confirm this. As for breathing in a paper bag, I believe that is one common way to deal with hyperventilation, which may also induce anxiety and thus lead to more of the same.
At this point Apple aren't going to persew it. The M1 spells the end of the hackintosh community
Agreed - framing it as "the app + system cost £37bn" would make you think that the app cost billions, rather than the app being approximately 1/10th of 1 percent of that figure.

My dad has a 3d TV and I found the main issue was just the fundamental physics - like unless the TV is absolutely massive like a cinema then there are fundamental limits on how "3D" it can appear.

This meant that even the relatively small amount of 3D content didn't really feel that 3D, it just felt like more realistic 2D.

And if there's only a small amount of content you might as well just go to the far superior 3D cinema for the experience.
I think we need a new journalism. One that can avoid the last 20 years of structured news. Though I think this is impossible now. Not without an outsized reaction by the population that doesn't even care.

I find it interesting that there seems to be a (wilful?) ignorance on the part of our government as to quite how big and powerful those corporations are.

There seems to be a bit of a "We're the government, so they'll have to do what we ask/tell" going on here I suspect. Probably coupled with incompetent IT project management that didn't bother to worry about the terms and conditions they signed up to, because that was too hard.
They're not talking about anxiety that makes sense here.
You being scared of your sister dying makes sense.
They're talking about irrational anxiety, like having a panic attack, because your stomach feels slightly funny, or because you slept weird, etc.
Those irrational anxieties are often times hard to pinpoint to an actual cause.
Like your sitting at home on a sunday and suddenly have a panic attack, without any immediate cause or threat.

> Can someone who knows more physics than I tell me if the question is even meaningful?

Any new physical property could potentially be exploited to improve some existing idea. The discovery of the electromagnetic force eventually gave way to WiFi and 5G. The discovery of the quantum realm for example has yielded the concept of quantum computing. If we can discover high dimensions, we can eventually interact with them and use them.
Elon Musk certainly DID NOT FOUND TESLA INC. Martin Eberhard and Marc Tarpenning founded Tesla inc in 2003. Sorry for the caps, but Musk invested later, after the first prototype (2004). Musk then ousted the original inventors from the company and sued them to for founder status. So, it's interesting that Musk is legally defined now as a founder of a company which he definately never founded.
It might be different outside of Europe, but we did go through a significant reduction in pre-flight times in our lifetimes: I remember scrambling with my family to arrive to the airport 3–4 hours in advance and spending all that time queuing.

Now for most of my flights I just check-in online, arrive to the airport an hour before departure, and spend 45 minutes and jaywalking around the airport while drinking overpriced coffee.
That's because MAME is distributed as a single executable which combines support for all the machines it emulates. If there was a mega 'multiple arcade machine FPGA core' that supported thousands of machines in one then you would need to do the same kind of installation management as different parts of that codebase matured. But when using FPGAs you normally have a seperate core for every machine being simulated. By the emulation analogy, you're actually switching between many different 'MAME versions', or single-game emulators when you switch between games on your FPGA.
I'm not sure you can call it an agreement in any true sense. Apple and Google dictated the terms for accessing the Bluetooth hardware in the particular way required. Many governments around the world wanted more direct access to the hardware than Apple/Google have permitted, or (voluntary or otherwise) access to location data. Google and Apple said if you don't agree to these terms, you don't get to access anything.

I'm not necessarily saying that's wrong or right. You could argue they're defending the user's rights against the tyranny of the British government. Or you could say they're constraining the user's and their democratically elected government's rights to voluntarily use data to help end a pandemic, while at the same time profiting off it themselves.

>What’s the angle here?

As someone who works professionally in this space, I can say that most commenters thus far have completely missed it. The angle here is Conversational AI in the Enterprise Call Center market. This is a market worth hundreds of billions of dollars annually. This announcement is almost certainly a reaction to the partnership between Genesys and Google to create Google Cloud Contact Center AI. I know a lot of people hate customer service chatbots, doesn't matter, companies are spending a fortune on them to replace agents and Microsoft/Google/Amazon want a slice of that pie.
From the Guardian article https://www.theguardian.com/technology/2021/apr/12/facebook-...:

> "But it quickly became clear that no one was interested in taking responsibility for policing the abuses of the president of a poor nation with just 4.5m Facebook users. The message she received from all corners – including from threat intelligence, the small and elite team of investigators responsible for uncovering CIB campaigns – was that the abuses were bad, but resources were tight, and, absent any external pressure, Honduras was simply not a priority."

We can assume that hostile nations have known this for awhile, and they have also been exploiting this. This is tragic but true.

Yep.

And "evil" is entirely subjective, one can easily say that Israel is evil for human rights and international law violations, and a similar argument can easily be made against the US, Turkey, UK, France, Saudi Arabia Iran as well.
So the US also signed the NPT where all the nuclear states also pledged to eliminate their arsenals... But we built a few more in '07. We also didn't sign the '17 treaty on prohibiting nuclear weapons.

Definitely not weird at all.
On the other hand bash is one of my favorite languages to develop for. It took many years to get proficient and you shouldn't try to do anything too complex but it has good sides:

1. The REPL is top notch.

2. Good documentation. Most commands come with a complete manual and examples are easy to find.

3. It's portable and has lots of available APIs, probably even more than C.

You sound stressed that there is a lot you don’t know. If you can be patient you can learn a lot in 10 years at a reasonable pace. I’d advise doing something like a “sweaty startup” just to get in the business mindset. This is the doing jobs for your neighbours or making stuff and selling it on eBay. The trick is selling people what they want, not what YOU are passionate about. Someone is more likely to buy a phone charger than a cool-idea-saas subscription. Use your day job to get leadership skills and spot problems too and learn a good all round “stack” ideally web dev based which you can reuse in your projects.

A visual cash flow tool for Small Business Owners or Professors?
Hello everyone!
I have a visual cash flow app, and I have been marketing it to small business owners. I have had a very hard time managing my business finances in spreadsheets. I have never been a numbers person so formulas in spreadsheets made my work 10x harder and time-consuming. I was looking for simplicity and an app that would help me understand my financial data with just a look.

I couldn’t find any, so out of bare necessity, I built one with the help of my team. It shows my cash flow projections and budgets in a simple chart and graph.

After launching a lifetime deal on Product Hunt we gained traction and few users purchased the deal and loved it.

But, Hacker News was the real game-changer. We discovered a niche we hadn’t thought of before. Professors who manage research labs in universities have limited resources to manage their grant funding and disburse scholarships to students. This segment has good scope and is really struggling with expense optimization and budgeting.

As per the advice of our current user who’s an associate professor at UWaterloo, we changed the terminologies in our app to suit the needs of the niche. We did our research and contacted Associate professors and Principal investigators on LI but we don’t have any response.

Now, I can’t help but wonder should we continue our efforts to market towards university professors or go back to small business owners?
What do you think? Should we change the current marketing plan and stick to the original? I really appreciate any feedback.

Thank you for taking the time out to read this.

> In 2012, I predicted that point-and-shoot cameras and camcorders were so dead that my son would never use them.

Point and shoot digital cameras are interestingly bad compared to cellphones nowadays. The camera will generally have better glass, better sensor, beefier battery, more space to house the components, but will get beaten by a 7mm thick phone in most circumstances. Amazing how much can be done just by crunching numbers harder and faster.

On the contrary, DSLRs and mirrorless cameras have held their own against camera phones. The hardware advantage is too vast to be bridged by software right now. Or maybe the camera manufacturers are starting to use some software tricks themselves in their newest stuff.
Bikes aren't great for the 'last mile' where you might get off a train and have a bit further to go. You can ride a scoot in pedestrianised areas too normaly, and you can't on a bike. Far harder to stash a bike behind your desk at the office, much easier with a scoot.

Of course the downside of this convenience is stealability.
I'm not saying that a particular technical approach is better, I'm just saying that from a product perspective the medical industry has specific requirements which are currently satisfied in Dragon and not in the generalised speech libraries Apple / Google have at the moment.

I've not got direct experience in healthcare, but do have experience in industrial voice, and this is an area where Apple/Google generalised libraries perform significantly worse than specialised software (Dragon is also big in this industry, albeit at the SDK level). In industrial voice the main requirements are high levels of background noise, restricted vocabulary (20-30 words) and people speaking very quickly.

> There seems to be a bit of a "We're the government, so they'll have to do what we ask/tell" going on here I suspect

That's the case (they are the government, they are in control, not Apple or Google), and certainly it should have been the case considering the situation. But that would have required the government to show some backbone and to use the power at its disposal. Instead it seems that the issue has been politically controversial so that the government decided not to act decisively on track and trace apps overall.

This is continuing with the controversy over "vaccine passports".
> the only limit is Shannon's limit, but that's only concerned with data rate.

But that limit, the capacity, is also the maximum possible limit of information transfer on the channel. Modulation schemes don't increase it or change it, they just push the achievable information rate of the system closer to the capacity.

POSIX shell is a bit quirky language and bash add a few quirks on its own, but you can write reasonably working shell code if you'll approach it like any other programming language: learn it (read guides, read man), choose a style guide (or write own), use static analyzers (shellcheck is a great tool), test code on different inputs, ask to review your code.

For some reason it is commonly believed that writing shell so easy that one don't need anything of this. Don't even need to learn it.
