So many companies have come and gone in the "print on demand" space. The barriers to entry are low and the market, while shrinking, is still quite large... If you consider the market those that send stationary (cards, letters, etc.). Having started a company in the space (engreet.com, since renamed https://www.thegreetingcardshop.com by its new owners), the fallacy is that most folks that send offline won't make the jump to digital. It's a different demographic that is slowly dying (sadly). From cardstore.com to Minted, there's still a market out there, but it's a fraction of the offline spend.
Aside from highly localized municipal efforts, the only way anything is going to be done about this is a top-down approach from the federal government. PR campaigns need to be conducted, funds for LEO training/equipment to conduct stings need to be allocated, all that. This needs to make going after drunk driving look like a drop in the barrel. As much as I hate wanting to expand the influence of our law enforcement bodies, I don't see any other way out of this epidemic.
> Microsoft’s CEO Satya Nadella recently emailed staff saying that if they didn’t support building a more inclusive culture, “your rewards, your career trajectory, and possibly even your employment will be impacted.”

Translation:

"If you keep pointing out we illegally discriminate during hiring and promotion, we'll fire you."

His comment is a jab at the people complaining about actual racism at Microsoft -- a veiled threat meant to appease radicals who throw a tantrum if people don't cater to their bigoted world views, which all call for institutionalized racism to be enacted.

Identity politics, and its manifestations such as "diversity", are merely authoritarian bigotry.

The entire basis of it is a kind of racial and sexual essentialism, one of the most thoroughly debunked kinds of bigoted beliefs. Without a belief in that tribal essentialism, none of what the "diversity" advocates argue for even makes sense.

"Diversity" is bigotry.

Launch HN: Trexo Robotics (YC W19) – Robotic Legs for Kids with Cerebral Palsy
Hi HN community! We're Rahul and Manmeet, co-founders of Trexo Robotics (https://trexorobotics.com)
At Trexo Robotics, we're building wearable robotic devices to help children with disabilities learn to walk, in many cases for the first time in their lives.
Video: https://youtu.be/3LW4LJIpa2o

We are both Mechatronics undergrads from the University of Waterloo. Rahul later completed a Master's in Robotics at the University of Toronto and I've done my MBA at Rotman.

We started this a few years ago when I (Manmeet) found out that my nephew, Praneit, has Cerebral Palsy, and that he would not be able to walk. Not walking can lead to contractures, hip subluxation, and many physiological and psychological issues for kids. We wanted to change that. We decided to use our robotics background, along with help from friends and the top rehabilitation researchers in North America, and in 2016, watched my nephew take his first steps using our device. Watching Praneit walk is definitely the proudest moment of my life, and we realized that there are families all over the world that can benefit from this, so we started Trexo Robotics.

The Trexo device is available for $899 per month (via financing) or can be purchased outright for $29,900.
It is an exercise and therapy tool, allowing children to get the benefits of daily walking at their homes. We decided to design it so that it attaches onto an existing walker. Currently, it only works with Rifton's Dynamic Pacer, but hopefully, we can add other walkers later on as well. Our controller allows you to modify the gait pattern to adapt to the needs of different kids and adjust the amount of force/assistance that the robot provides on each joint.
We are already launched, with kids using it to walk thousands of steps daily. It has been amazing to see the interest of families.
Our device is available for pre-order. Our 2019 production is already fully reserved, and we are now taking reservations for next year.

Really interested to hear the HN community's thoughts on our approach, and experiences families or others have had in this space.

Let's say you're right. Then shouldn't we solve that instead of jumping straight to price controls?
Not surprising, since recent hype around luxury clothing brands was formed in Instagram. Checked now number of people I know who follows accounts of these brands: gucci - 3, versace - 0, louisvuitton - 4, dior - 2. None of them can afford their products and they aren't especially interested in fashion design. What these companies did to achieve that level of marketing? It's probably much more effective and insane than traditional "glossy magazines".
It sounds like the issue is people in some sort of management or leadership role who are also leading protests in the same area (AI ethics)? This isn't exactly a conflict of interest, but it sounds like a conflict of something?

My commute in SV is entirely surface streets (by design). Since moving here I have observed what I call the "California stop": at a red light, drivers will stop 2-3 car lengths behind the next driver. Enough that a clever smart car driver could comfortably pull into the space.

Every time I see it, the driver is looking down at what I assume is a phone. They are so eager to get back to their phone they stop the car early.

I agree that we need a better term, but I don't perceive it as being co-opted by the alt-right so much as a pejorative that gives the user an air of bad faith. I want a neutral label for people who advocate for race/gender caste systems in the name of "equality" and who override standard terms (like "racism", "equality", "white supremacy", etc) with opposite meanings. It would be really useful for advancing the conversation.

Rust is the same in this regard, you can bind it to any other language. And it doesn't have the horrible downsides of C. So why not use it?

That's an issue as well, and this of course runs deep. But starting somewhere should be still possible.
No thanks. We should probably try to scale back corruption rather than ramping it up.

Yes, the successful drug companies make a high profit margin, but you're ignoring all the companies that spend hundreds of millions and then go under because their drug doesn't work.

Their research is no paid for by the US gov't. Basic research is heavily subsidized, but basic research doesn't get you a drug and basic research is the cheapest part of the entire process. They are still shoving billions of dollars into bringing drugs to market, again, often not successfully.

I agree with the basic sentiment that EVs have potential but aren't quite there yet.

One issue that I've seen raised a few times now is how honest the environmental credentials of these EVs really are. Sure, you aren't emitting pollution from your petrol/diesel engine as you drive. However, you have the emissions from whatever electricity source you use for charging instead, which obviously depends on how environmentally friendly or otherwise your power supply is. Crucially, you also have the effects of manufacturing these vehicles. Particularly when it comes to the batteries, those are still very significant. On top of that, batteries for EVs are heavy, and shifting all that extra weight around has a cost as well.

Just last week, there was a study being widely reported that suggested the true overall lifetime CO2 emissions given typical lifetime and usage levels for a car would make an electric vehicle worse than a diesel one of otherwise similar specification, much of this due to the hidden costs in mining key elements used in the battery.

Given that some of the materials involved are also relatively rare (or at least relatively difficult to supply viably in large quantities) I think the jury is still out on whether the modern generation of EVs will bring the big improvements that some of the environmentalists are hoping for.

Edit: To those anonymously downvoting, it would be more constructive and probably a lot more interesting to discuss actual facts and scientific evidence. For example, if you know of substantial, robust research on the environmental impacts of mining the materials needed for EV batteries on a scale where these vehicles become mass market rather than a niche product, please share it so the rest of us can learn something. Likewise, if you have substantial knowledge about the likely efficiency of improving EV technology, charging facilities and the sources behind them compared to other new or evolving models for powering vehicles over the next 10-20 years such as hybrid models or alternative fuels, please comment accordingly.

I'm perfectly content for a phone to detect via GPS/IMU that it's in a moving vehicle and send up a big angry prompt like "Please confirm that you are a passenger and not driving this vehicle. Phone interactions are being logged and will be available to law enforcement if a collision occurs."

I say this as a bike commuter who sees phones being used at stoplights every day, and as a parent of kids who walk to school. But also has a driver who occasionally fiddles with Google Maps on the road and could use the reminder myself.
The 3DS has a sandboxed BASIC implementation available complete with exporting and loading programs (http://smilebasic.com/en/), so other programming-in-a-VM games would probably be fine, presuming the developer was actually upfront about that at the time so proper security and content-rating testing could be done.

And just think about what most file and I/O wrappers, that are part of the standard library in most higher level languages, e.g. file objects in python, streams in C++ etc., naturally do: They also just wrap (for example) POSIX file descriptors, which are handles, with their own handles, i.e. the file object/Stream/whatever.
My discipline comes from a lifetime of sports and has carried over to my work life (even though I now do martial arts as a hobbyist instead of competing as a college athlete); many of these can be read as workout / health points but are actually applicable across your life.

It starts from the long-term goal: if you want to be extraordinary, you need to do things differently than the ordinary. People are going to give you a hard time about some of the changes you're making, so you need to be ready to ignore them and accept the fact that if you want to have a different level of discipline than others you need to do things differently.

Discipline is compound interest in your life - you are doing the little things the right way every day, and all those pennies are eventually going to add up into millions. This applies to food, working out, pushing on projects, learning new skills etc.

The best advice is to make it easy for yourself - pick a FEW, SIMPLE, things that you can control and start from there. Stop eating the same snack or having a glass of wine after work. Start waking up at 6 am. Then evolve to going to the gym from there. Build habits.

You also need to accept that you're not perfect, and no man is an island. This part was the hardest for me - I built up walls around myself (thinking that I needed to keep my habits exactly as they were since they had gotten me this far) and thus cut off opportunities and other people. Eventually I was able to be a bit more chilled out while still keeping the discipline in the right areas. I found that 7 habits of highly successful people really helped me; I also recommend "Wooden on Leadership" and "The Score Takes Care of Itself" as examples of champions putting this bottoms-up approach into practice over years and reaping the rewards.

There is no shortcut. There is nothing fancy. Control what you can control, don't worry about the rest of it, and trust in the process. Feel free to message me if I can be helpful
> First we need cheap options for all before we should worry about luxury treatments.

In this context the "luxury treatments" are drugs under patent and the "cheap options for all" are generics.

And then we can identify a specific problem -- we don't have enough generics because unless a drug is under patent, nobody has the incentive to pay to put it through FDA trials.

But you can't solve that by removing the profit from the "luxury drugs" -- that only makes it worse. Then nobody has the incentive to pay for FDA trials for anything.

The actual problem is that FDA trials are an unfunded mandate. Either they need to be made significantly less expensive somehow or the government needs to fund them itself so that more unpatented generics can actually get approved.
Ask HN: Best place to sell a web app?

Depends on the city, most American cities aren't structured in a way that makes sense for public transportation. They are designed around the assumption of car ownership. And that still leaves the question of how to bridge the huge gaps between cities without cars.

As far as I can tell, the idea of “same size means establishing a bijection” appears (in a formal sense) at essentially the same time as it was discovered that there are pairs of infinite collections where you can’t do that (i.e. with Dedekind and Cantor in the late 1800s), so I don’t think that second definition ever actually existed in a meaningful sense, although I think your intuition seems reasonable (albeit “bending” holds the wrong connotation, imo, as this would seem to be a rather principled generalization of an existing concept rather than an arbitrary decision among a number of somewhat reasonable options). Regardless, I’d be very interested to read a survey of the history of ideas about cardinality/ordinality if you have a good one, since modern treatments of these ideas are radically different than how humans understood them even 150 years ago.
I really like this paper. There's a large class of problems where tracing GC is very suboptimal from a performance/efficiency perspective but classic manual memory management is unacceptable from a security/correctness perspective.
I believe there are two parts to this argument:

1. articles should start with a brief summary of their context, arguments and conclusions.

2. articles should explain their terminology.

The first point I agree with (and believe most do). But the second point is arbitrary, and in my personal opinion, the linked article is fine in this regard (anyone familiar with X-Windows should be familiar with Wayland as a concept, and every single article related to Wayland cannot be expected to explain core abstractions like compositors).
