Nobody knows about PAUSE frames until they bite you.

I found out about them when someone at a place I worked wanted to design a custom Ethernet driver for an embedded device. There was no good reason for it, could have run the regular one shipped for that device (it was an RPi equivalent kinda unit).

So there they went and months later, it emerged. Everyone was amazed: oh wow handcrafted Ethernet driver, impressive.

Except what ensued was months of debugging and wireshark captures. Not handling PAUSE frame and flooding the network with packets took a good chunk of that time. Of course it was blamed on stupid switches and broken protocol and not on the bad decision to re-write a known, well defined and stable protocol without a good reason to do so.
But other phenomena correlated with sunspots do cause UHF interference

What would be some examples of such phenomena, bearing in mind that we're talking about very short-range wireless links in a band shared with primary military users?

It's not as if conflicts in that band haven't arisen before:

This doesn't really help for anything except for content editing (e.g., markdown). Consider the above example: the original poster now has all these files they've changed on disk. The best case scenario now involves opening all those files up one by one and pasting them into the browser's textarea. (Can you change multiple files this way and wrap it up into a single atomic commit? Whatever the case, this actually results in a lot more pointy-clicky, not less.)

A patch is a unit of change. Historically, that's the type of unit that the open source world has operated with. The only reason we're having this conversation right now is because GitHub decided to build on top of pull requests instead of patches for lock-in reasons. GitLab has no such motivations, so it's silly to continue following them, especially since Git has had native support for patches from the beginning.

Just support patches already.

That second discussion got heated quite fast. I agree with the downvoters though. 3D printing a medical device is not something to take lightly.

Edit:

Here's why I agree.

You download this design from the internet, and 3D print the parts. You then assemble it. Awesome!

Some time later, you get an allergic reaction. You use the pen, but it fails to work correctly. Who's responsible? The designer? You (if you're alive)? The printer manufacturer? Your friend who emailed you the design? etc.

There's a reason why even getting such a simple design considered for FDA approval and certified for use on live humans is such a long and complex process. It's easy to make something that works some of the time, but it's extremely hard to make it work essentially every time, especially in life-or-death scenarios.

Of course, the price hike is terrible and the company behind it deserves punishment, but that doesn't make it OK to endanger the lives of people.

This is taking startup minimalism to new levels. i.e just build a web page with no actual code. But this is what Sam Altman advocated in one of his lectures - how these students stuck posters everywhere on campus about food delivery with no product.

Scarcity demands innovation. I don't think its being taken lightly; more like, "a private company is gouging medical users and the government won't step in". Not left with many options when your life depends on it.

EDIT: Alternatively, a "better" temporary solution would be to arrange for the import of these from Canada, where the price is fixed by the government.
How many people will this price hike kill? I'm sure that's estimable.

This doesn't really describe how development is going to get faster. It just lumps the next big leap into unsupervised learning - which isn't really an understood concept as the author describes.

The "unsupervised learning as black box" argument always bothers me. It looks too much like the consciousness debate. The theory that UL is an emergent property from massively scaled NAIs is at least plausible IMO, but that wasn't really discussed.
But with day trading you have the same problem you have with poker - there isn't any way to know if you're better than other people. Your advantage will be so small you can lose money month after month even if you've managed to tilt the odds in your favor. Worse, you can easily trick yourself into thinking you can make money on average after a prolonged lucky streak.

In poker it's possible to be enough better than the competition that your advantage is obvious (to people who are similarly skilled, at least). I'm not sure that's the case with day trading.

what keeps me from exercising is me.

i think it helps to have a partner or group to exercise with.

example, i am more inclined to exercise when my workmates or relatives invites me.

it also helps to have a purpose in exercising.

I hate to be the negative guy, but isn't this the obvious, standard, well known way of building a greenhouse? You want to prevent hot air from escaping, you put up something that contains the air. An actual greenhouse doesn't really rely on "the greenhouse effect" of allowing visual light to pass but being opaque to infrared. It's all about preventing hot air from rising. This can be easily seen in polyethylene windowed greenhouses, which get just as hot as glass greenhouses, even though polyethylene is just as transparent to IR as to visible light.

That part of the piece seemed like something the MIT press office coaxed out of them to get a human interest angle TBH.

Really, most of their improvement over the 2014 version seems to come from the spectrally-selective absorber coating, which is a lot more expensive than bubble wrap. So they say this solution might be ~10x cheaper than existing solar destilling plants, but they also say it will need replacement ~10x as often. So depending on exactly how the numbers work out, this might mean slightly cheaper, more labor-intensive desalinisation plants, but we're not covering any deserts just yet.

This also happens in compltely normal operation, like if you're using a TCP-based MPI implementation and do an all-versus-all message send. The destination buffers will fill quickly from all the senders, the receiver drops the packets, TCP sees that as a timeout after 250ms, and requests a retransmit. In principle, using PAUSE frames allows the sender to get feedback to pace its sends.

Took me a long time to debug my MPI performance problems because of this.

Ask HN: EBook Best Practices
I am hoping to get some personal stories from HN...Please feel free to link to prior write ups about your experience with your own eBook(s)

1. Genre of your book(s)?

2. Distribution (Amazon, iBooks, print, etc...) and outcomes (% of sales)?

3. Pricing?

4. Marketing (if any)?

I previously posted https://news.ycombinator.com/item?id=10182723 about my Dad's project to transcribe ~600 letters after nearly a year he is set to publish volume 1 (not bad for an 82 year old who is legally blind). I am going to assist him with the distribution, so while I am formatting for (ePub and mobi) I thought I could get some HN insight/experiences to help on the next steps.

The current plan is distribute this non-fictional work through Amazon, Apple iBooks, and directly through the book's website (dearmomebook.com). There is no marketing budget, but from the prior HN post we gained 150 emails of interested readers so I plan to notify them when the book is available. The price is harder, my Dad has left that in my hands and the obvious balance is getting the book into the hands of the most readers while not sell my Dad short. Uniquely, I feel the largest market for his book is overseas Asia, South East Asia, and maybe in Russia...so perhaps audience demographic/nationality may be a beneficial bonus question if that information is readily available.
Let's not pretend that there's a properly functioning market here. The only reason for the price hike is to line pockets, not because demand fell or it suddenly became that much more expensive to produce.

In a society where some mild form of anorexia was the norm, that headline would be actually insightful.
This article describes using JWT in a web-server environment where session cookies are likely a better solution.

JWT and Stored Sessions have their place.

If you are running a single web server and your client is connecting via a webpage (or possibly an app), then storing session data in a key-value store is probably a better solution.

If you've got multiple (micro) services being accessed via an API, I say JWT all the way.

JWT's can be expired (which the author does not address), expiring does not mean the user needs to login again. The app logic can request a new JWT based on some internal logic, maybe the user needs to login, or maybe they just get issued a new JWT.

If your JWT key is compromised, you've likely compromised something else on your system as well. You are no longer secure and need to do something about it. JWT is the least of your worries at this point.

The "cannot push messages" doesn't make any sense to me. If you're polling the server, you poll with the JWT, the server unpacks it and sees which user made the query. You can put anything you want into a JWT. Which leads to the next point.

Data overhead... really? I just checked our JWT, which has some data about user, expiration, permissions and it's 200 bytes. You can add much more data and you still won't likely hit the 1kb data. Even if you did. 1kb it's 1kb, I'd suggest that is if you are being irresponsible and putting way too much into the JWT itself.

I'm not saying JWT is perfect, as I said, a simple website, use sessions, but the way Rahul has picked apart JWT is like a chef trying to cut a cake with a spatula. It works, but you're better off using a knife.

Interesting.

I can't imagine that I'm alone in this, but when I use the computer, I'm usually trying to get something done. Now, I realize that my security systems are often trying to help keep me from doing something foolish, but much like software updates, I'm not interested in taking my off of the task at hand.

I'm not sure how the software is supposed to wait until after I've done something stupid, but I agree that I would be more available (attention-wise) to take note of it afterwards.
I could see this being adapted as a good v2 for http://riemann.io/dashboard.html ;

Obviously there are lots of dashboards in the world, but while there are substantial differences in UX (OpenMCT seems more approachable whereas riemann dash is very simple & "efficient" over a tall learning curve), the core "feel" of nestable / composable realtime data widgets between these two is noticeably more similar than either vis-a-vis any other relevant project I've played with.

That is likely true to some extent. The question is to what extent?

100% of the surplus accruing to pharmaceutical does not go toward research. Of the X% that does go to research, that marginal increase is likely not as effective as the budgets before the increased margin.

Also, patents shift effort from areas with low patentability prospects to areas with higher patentability prospects, even if the rate of return in terms of public health would have been substantially higher if the former opportunities were maximized first.

For that and many other reasons, the net social gain from pharmaceutical patents is contentious. Many economists have argued that the only justification is improved incentive to cover the cost of our expensive regulatory environment. Patents for almost everything else? Almost certainly a net loss.

There's little evidence that patent monopolies are needed to induce investment, generally. Don't forget that there's almost $100 trillion in liquid, investable assets floating around out there. There's more than enough capital to fund anything with even a tiny predicted profit. But individual capitalists want to maximize their returns, and monopolies often provide better margins. That good patents attract more capital is not evidence of anything; capital will first go to anything that promises higher returns relative to anything else, even if the net effect is reduced overall wealth creation for investors.

Imagine two countries with equivalently sized economies at year 1. The first is run by a dictator who will use the power of the state to extract wealth from the citizens. Part of the process involves giving sweet-heart deals to foreign investors, partly as a way to off-shore the money. For those investors the returns are 20%.

The second country is a stable democracy with low corruption. Politicians only seek foreign investment when it makes fiscal sense, and the terms only provide returns of about 10%.

In the short-term, where do you think all the capital will go to first? Over 30 years, where do you think most of the net global wealth creation will come from?

Ergo, that investors prefer investments backed by patents is proof of nothing.

That the U.S. and developed countries are leaders in research and investment also proves very little. We're also leaders in areas like consumer and industrial design, organizational management, etc, with no or minimal regulatory protection. We could be (and arguably are) leaders in technology despite protections, not because of them.
Dying because you can't afford a device you need is also not something to take lightly. It may not be a good idea, but blame should lie with the manufacturer for raising the price to such ridiculous levels.
-Don't say no to opportunities that take you out of your comfort zone. Embrace them and remember the variety of experience when you are younger pay dividends later when you are even more risk averse.

-Take your passions seriously. If you find something that interests you, go for it all the way even if you're tired, lazy, busy.

-Be the one who initiates things with regards to social and business relationships. It's okay to get burned but keep leading by example.

-Stop living in your head. It's great to have an imagination and think steps ahead. However until you can make it a reality, your head becomes your biggest obstacle.

-Make exercise and other healthy habits a part of your routine. No, you won't be a robot. You'll actually be sustainably developing your sense of discipline.

-Following the money may leave you stuck with just a number but no further prospects. Make sure you're keeping yourself marketable and taking side gigs to keep yourself sharp.
