Uh, maybe in some places in Canada? I grew up in Nova Scotia and seeing a doctor with an appointment was possible within a week, emergency was always possible right away. (Had 34 stitches by the time I was 17 due to growing up on a farm so I had a lot of experience.)

Here in Austria it's even easier, I can go directly to my family doctor at any time and wait ~hour with no appointment necessary. Xrays, or other things are usually possible same day and even elective surgery that improves quality of life is free and is plannable within a couple months with the recovery time as paid leave from work.
> Never mind that the average wait time to see a doctor in Canada is almost 20 weeks...

This is just false.

The number you're referring to is from here: "Specialist physicians surveyed report a median waiting time of 19.8 weeks between referral from a general practitioner and receipt of treatment—shorter than the wait of 21.2 weeks reported in 2017. This year's wait time is 113% longer than in 1993, when it was just 9.3 weeks."

It's for receiving treatment from a specialist (surgery, etc.) not 'seeing a doctor'.

Somewhere around 40% of Canadians reported being able to see their primary care physician the same day. Very few reported a wait of longer than 7+ days.

Many parts of Canada are very remote. The average waiting time for someone in a major city is not as long as that.
It is not twenty weeks to see any doctor: it is twenty weeks to go from a referral from a general practitioner to receiving treatment from a specialist [0][1][2]. I’m not sure if things like consultations are counted are as treatment or not.

I understand that. I was on prozac for years. I chose to come off it because it was messing me up, otherwise I'd have been happy to take it for the rest of my life (why not?)

I was aware that if the blackness returned and going back onto prozac failed to work (which can happen) then my lifespan would be a few months at the most.

People without really bad depression can't understand how bad it can be. Death really is better.

>Yahoo) requires users to submit their websites. It worked well enough.

It didn't work well enough because back in 2000, Yahoo was one of the first companies to license Google's search engine. (The previous year, AOL licensed Google's search engine.)

Yahoo incorrectly thought that their "portal" and user-submitted "directories" were more important to web surfers than search algorithms like Google's Pagerank. They eventually realized their misjudgment and then tried to build a Google clone through acquisitions like Inktomi and Overture:

Median is the 50th percentile, it's unaffected by Bill Gates. So half the median is a better measure than half the mean.

However as you say it's still a measure of disparity, not an absolute level.
The biggest problem with full electric powertrains is size of batteries and its weight. Keeping the size of batteries small and weighing less is a bonus in ICE car conversions, like I mentioned in my initial comment. Plus better replenishing time, which in most hydrogen fuel cells cars is around 3 minutes.

Edit: the Riversimple Rasa uses a hybrid lithium based battery/supercapacitor pack for this purpose.
I don't think it's very complex. Only look at the target users! :-)

Jokes aside, lack of basic code protection (aside of script minimization and/or obfuscation) it's that prevents me from using Electron/Atom/whatever. I know anyone could decompile a C# application easily, but I find the javascript case worst.

Do you know any commercial applications using any of these solutions? (I'm speaking of shareware / paid software, not "Whatsapp desktop" type)
Also, assuming reasonable values for the weight of your wife and the power draw of your appliance LEDs, if she has to bend down to unplug an appliance she burns through an appreciable fraction of the power savings. For example, if she's 50 kilos above the waist, and the appliance LED draws 50 milliwatts, then the energy she burns straightening up after bending down 1 meter is equivalent to nearly 3 hours of leaving it on:

(50 kilograms ⋅ 9.81 (m/s^2) ⋅ 1 meter) / 50 mW = 2.725 hours

Of course, your wife doesn't run on pure electricity - the energy she expends probably took a very inefficient route to get to her. On the other hand, depending on what she eats and where you live, agriculture may still be a greener form of energy than wall current. If she's vegan and your power comes from coal, it might be worth it; if she eats beef and your power is hydroelectric, it definitely isn't.

Easy solution: install switches at waist height. But be sure to factor in all that extra resistance from the longer power wires!
Thought the same. 2000 pages - Basics was probably an understatement...

Just looked at a few pages and it seems really illustrative. I am just a light-weight mathematician as a computer scientist, but I really would have liked such a comprehensive script for studying. I hate it when profs reduce everything to minimal definitions and expect studends to make sense of it. There are countless books but it is always a gamble that they focus on the topic at hand and don't suffer from the same problems.

This even gives you "motivational examples" which are extremely helpful for comprehension in my opinion.
Name, DOB, and address is available via the Electoral Roll. While I don't think NAB is blameless, at some point the blame lies with companies that accept insufficient forms of authentication.

For example, to transfer funds with my bank, I get texted a 2FA code and this is a mandatory requirement for online banking at CBA.
Every time I hear about Electron, I have mixed feeling about it, is it :

* one the best thing that happened to desktop software as it enable web developers to build desktop portable app

* one of the worst thing that happened, because it makes the desktop world rely on Google and decrease even more the expectations on how much resources an app should consume

What are your opinions ?
> Oh awesome! This one also has a tiny filesystem and prompt, but no UI for typing machine code in, is that right?

Yes, but it offers more to the programs that it loads. There's a trade-off when you go this low on disk space!

> But the filesystem supports more than one sector per file?

SaxOS supports half the disk, but each file has to be 512 bytes [1]. There are potentially work arounds for this limitation of one sector per file, but it's just hacky. (For example, you could name your files txt0, txt1, ... - or you could leave some header information in your program's file for more data.) I will fix this in a future version though, the plan is to keep loading sectors by the same name in the file table.

> Saxos is open-source, unlike BootOS, even if maybe that would be clearer if you used a widely-recognized license.

When I wrote this I had no idea about licenses :) I will look to update this, but the project is mostly just archived for now.

> I don't think BootOS tries to export its filesystem API to user programs. BootBASIC in particular doesn't seem to have a way to save and load programs.

It takes very little to extend the functionality of your kernel to your implementing programs, hopefully BootOS will do this in the future. At some point I want to write a simple self-writing documentation (using the comments structure) so that I can always produce up-to-date documentation for the OS.

> Brilliant work!

Thanks!

I was trying to build a very small low end compression algorithm for it to, but unfortunately I came hard up against entropy. The idea worked (as I envisioned it) but it had the effect of just transforming the dimension the data was stored in and adding unthinkable amounts of computational power and memory being required to get it back.

> (Apparently I heard about this before and never looked at it? Because I have a clone of it on my laptop dating from September 14th.)

Awesome! My plan for quite a while has been to write a small book and guide people through building their own very simple OS. I think people building their own 512 byte boot-able kernel is a nice intro into OSes whilst also having enough limitations that at some point you can say "this is complete". Anyway, it's what I wish had existed when I first set out may years ago!

Speaking of which, I must give a shout out to MikeOS which is where I learned about assembly and OSes [2].

Oh I dunno. A potentially serious side effect of clinical depression is death. See my other comment https://news.ycombinator.com/item?id=20572927

The side effects of prozac and gamanil for me weren't at all nice but they were far better than the blackness.

In those circumstances, 'could' could be quite good enough for me.

Too many wealthy Americans suffer from some version of this. If you are born to wealth and grow up in wealth I guess your viewpoint of the universe won’t be a very accurate one. The disproportionate power that wealth grants to you then becomes even more destructive.

Thalidomide. One enantiomer is a great morning sickness drug, the other causes catastrophic birth defects.
Yes, that's exactly the reason. They are filtering racemic Ketamine just so that they can patent and upsell it at exorbitant rates.
I'm not sure I understand the question[0] fully but thalidomide? https://en.wikipedia.org/wiki/Thalidomide

"Thalidomide is provided as a racemic mixture of two enantiomers; while there are reports that only one of the enantiomers may cause birth defects, the body converts each enantiomer into the other through mechanisms that are not well understood."

[0] because a racemic mixture (https://en.wikipedia.org/wiki/Racemates) is a 50/50 mix of enantiomers: "In chemistry, a racemic mixture, or racemate [...] has equal amounts of left- and right-handed enantiomers of a chiral molecule" so if you took a racemic mixture surely you'd be getting a combination of the enantiomers' effects?

I have used Tk (through Python's tkinter) for several touch-based "kiosk" applications. It is surprisingly useful and productive for that. What you need is small (~100 lines) custom ttk style which adds larger padings to buttons and such and maybe makes it look "modern", flat and colorful and that's it. It certainly makes more sense than making such things web-based.
It would be great to give this feedback to the Blender team. Once you're used to something it can be difficult to see the parts where it is more difficult than it could be. So Blender needs continuous feedback from people who haven't used it that much before.

In EV conversions I've seen, the fuel gauge is typically repurposed to display battery state of charge, and the tachometer to display power output/regeneration.

That is something has always confused me a bit. Many people tend to object to universal system on the basis that it leaves it up to the government. But if you don't have universal systems the government, and the companies operating in the market, have little incentive to take care of its citizens. Because the cost of not doing so is left to you. Even if you want to argue that a health care system is a factor of how healthy people are, it is the universal systems that have the incentive that people are healthy. It is those systems that more often regulate things like transportation or drugs as public health issues.

> “Math Basics” is quite the misnomer—it gives the impression that one would need to study all of the contents of this book to be an effective practitioner in CS or ML.

To me basics mean that if you study this entire book you won’t be able to understand ML otherwise it would say comprehensive. Furthermore the math presented in this book are all taught in 1st year courses for most CS programs I’ve encountered.

> Keep in mind it can take an hour, and sometimes way more, to really absorb a single page of a math.

Learning is a personal experience and happens at differing rates for different people. While I do agree this book is rather terse and would serve as a good reference any added explanations around the proofs would force a split to multiple publications so I can see why the authors chose to present it in the way they did.

I've been saying for about 5 years now that this is potentially a billion dollar market waiting to happen. Even more so now with many large economies looking at aggressive forced electric car purchases. Congratulations to those guys for getting the business off the ground.

Another potentially massive market will be in making "legacy" cars become autonomous, but that's still unknown as to when that market will really hit off as the technology still isn't there (or approved of by law makers). Still, moving first on that could really be big.

In general I think there is a massive market in old vehicles that isn't been capitalized on. Of course you have scrap, part selling, fixing, etc - but some of these working vehicles (with little wrong) get scrapped for no reason. From a green carbon footprint stand point, a lot of the car's carbon footprint is in making the vehicle itself. When you buy a 10+ year old car I think you're doing more to save the planet, regardless of whether the emissions are higher.
Uh, I don't mind if getting to the doctor or dentist for a non-urgent problem takes a week or so. I also don't mind if you have to pay a nominal fee (we've got a flat fee of about 20€ for a doctors visit, regardless of what treatment you receive).

The important bit is when you have an acute accident, you'll get treated immediately (without checking your insurance first!) or develop life-threatening illness like cancer, you get good care without going bankrupt.

In this regard, most European countries are vastly better than the United States.

It's also important to know that Europe is not a single country and the health care varies a lot country by country. I have heard horror stories about the health care in some southern European countries that might be a lot worse than the US.
