Ask HN: What is a simple product that you would pay a monthly subscription for?
I am planning on creating a new online business for a simple product which people would pay money for. Would love to hear your thoughts. I have a few ideas:

1. A simple service which notifies you about tips through various channels (slack, email, telegram). It rotates through a list of your tips that you've created. These could be programming tips, quotes etc,.

2. A service which sends you a kindle document containing all your pocket links every week.

3. A service which converts an open source code repository into a readable ebook which can be read on a Kindle like device.

4. A service that allows you to create a private website and share it with only a few users (authentication via email).

5. A simple blogging engine driven by a Dropbox folder and Markdown.

Vision navigation systems are pretty effective these days - 'avoid big rocks' seems like a straightforward use case for that. And clearly the landing systems would need to account for some degree of rough terrain. The wheeled drones go through a tremendous amount of testing of the various conditions they would encounter - a flying drone would go through the same engineering rigour before it was approved for the mission.

Also, I believe most of the activity of these devices is planned out well in advance, so you could even add human review to some of that process. It could take a short flight for a few high-rez pictures, land right near (or exactly) where it took off from, send the pics back to earth for review to pick it's next landing spot.
These appeals to saving lives would be entirely unnecessary with just one small fix.

The supply of blood would be dramatically increased if the United Blood Services would simply pay $50 per unit. After testing and transportation, a unit of blood costs hospitals about $400. With transfusion services, the hospital charges the patient between $1400 and $3000 depending on provider. Adding a mere $50 to that in order to permanently solve supply constraints would be a huge win for everybody.
i can understand this sentiment, but there are many mental illnesses that bring pain to the people around the afflicted. why do we single drug addicts out for judgement?

At some point a drug addict, predisposition and circumstances aside, had to make a choice to start taking drugs. Someone with a mental illness never chose to flirt with mental illness, they’re just mentally ill.

Now, I also have a lot of sympathy for drug addicts, because we can’t ignore predisposition and environment, but it was still, somewhere in their past, a matter of choice. I don’t think that means we should hang them out to dry, but it’s not quite the same as someone who was just born sick. Of course that does exclude the hefty portion of the drug addicted populace who found their way to drugs as the result of a mental illness...

ChromeOS is very nice for non-development browsing/writing/music listening which we all do, the 12-13" models are a good form factor and have good battery life. Not to mention they're usually <$300 for the lower-end models.
I have the same setup and it's great for some development tasks, but its single-core speed can't match the latest processors. I actually installed Linux on my company-issued MBP and I run a bunch of dev tools on it via Xwin from my z620.

Businesses don't have a right to exist. If you need to do something unethical in order to keep your business afloat, maybe it deserves to go under?

Granted, the proprietors of said business may not see it that way… but no one commenting on this article is representing the Silicon Valley Community Foundation. As consumers (or, in this case, donors) we should hold businesses to a standard of absolute good. The market incentive to be ethical only exists if we create it.

The thing about science is that it's fairly easy to prove something is harmful. It's darn near impossible to prove something is safe. Organic food isn't 100% safe, and is more likely than conventional to be contaminated with pathogens such as e coli. But after 25 years of use with no proof otherwise, I'd say GMOs have met the burden of proof.
The experience I had with its touchpad and screen. The screen is mitigated by buying the FHD version. But the touchpad never works right. Basically two finger scrolling has never worked right. It’s almost like lag in that it’ll keep scrolling after I lift my fingers. Only the actual experience is worse than that. Issue persists past firmware and driver updates/changes.
In some ways couldn’t that be considered social engineering through ai? If the training set shows bias and this so does the algorithm, it’s a reflection of reality. Manually changing the algorithm to influence society on a grand scale is dystopian. It’s a dangerous path that sounds humanitarian but is really authoritarian.

> GPS is already less accurate the further from equator you get, as all the visible satellites are increasingly on one side of you.

Not contradicting you, but just to be clear: GPS satellites are not in geostationary orbits above the equator, or even in geosynchronous orbits. Rather, they are in medium-Earth orbits and their time-averaged density over the Earth is only a little lower over the poles as the equator. At some parts of the month, there are as many visible at the poles as at the equator. See Fig. 4 here:

The GPS Wikipedia page also has a reasonable illustration of their orbits.

Short Sharp Notes on Machine Learning
Can someone check my math/physics? The atmosphere on Mars is about 1.7% as dense as on Earth, meaning that a propeller on Earth will generate 58.8x more thrust than on Mars. An aircraft on Earth will weigh 2.6x of its Mars weight. Drones probably need a thrust to weight ratio of at least 1.5 to be reasonably maneuverable. A drone that has a 1.5 thrust to weight ratio on Mars would have a thrust to weight ratio of 1.5 * 58.8 / 2.6 = 33.9. That is certainly higher than hobbyist Earth drones that I’m aware of, but not terribly hard to imagine. The craziest racing quadcopters I’ve seen have power to weight ratios of around 10.

I've never heard of it being understood at all.
Mars is 140 million miles away from earth on average. Even if you could detect signals from GPS satellites on earth they would all be at a single point in the sky.

However, that does bring up an interesting idea. Maybe rovers could navigate using the position of the stars? It doesn't require you to launch 4+ GPS satellites into martian orbit.

> 1. Both models I’m interested in cost $2000. I’m worried that there’s a 20% chance I’ll end up with a camera that I never use because I don’t like it, and therefore have a $2000 device which is essentially useless to me. I value my spare time at roughly $25/hour. On financial reasons alone, how much time could I reasonably spend on doing research?

> ~16 hours. Because 20% × $2000 / ($25/hour).

I'm not sure if I have understood, I think in this example, the expected loss here is, 0 x 80% + -2000 * 20% = -400, thus the answer, is my understanding correct?
I see. Thanks for the clarification!
Look up Dell Developer Edition to see the lineup options. I went with a beefed up Precision 7710 that can handle 3 hard drives (2 NVMe and 1 2.5) and 64 GB of RAM personally. Started with just 16gb and 1 drive but I like the room to upgrade over time. :)

Opinions on this article ?
Dell XPS series looks fantastic from the outside, but there are a few things that stop me from wanting one, that I've mostly observed from other owners of XPS laptops, having not owned one myself.

1. The keyboard. It's apparently not so bad once you get used to it, but compared to typing on my Thinkpad I find myself unhappy with it; it feels spongier in comparison, and the key travel is pretty short (though not nearly as bad as the Apple butterfly switches.)

2. The docking situation. Thunderbolt 3 docks are not really that appealing to me because it becomes difficult to drive many displays at 60 FPS with them. In all fairness, the Thinkpad workstation dock can also only drive 2 displays 60hz 1080p OR 30hz 4k, but at least it's reliable, and my Thunderbolt port is still free if I want more displays at the cost of convenience.

3. Linux support is actually really awful. The XPS 13 developer edition is supposedly an exception, but I have heard that it's really only well supported with the exact version of Ubuntu it ships with, and that updates have occasionally broke the system. Admittedly, the same can be said for some Lenovo laptops. My P51 is pretty bad under Linux (though it's gotten to the point of being usable, thankfully.)

4. Reliability. A coworker has replaced his XPS like 2 or 3 times now, and one of the chargers also died. I hope that's the exception. Obviously even Thinkpads are not as rock solid as they used to be, but even though I found this level of failure to be pretty extreme, it lines up with what I've witnessed with other Dell laptops and is one of the primary reasons I've never owned one.

Honestly, the choice of laptop comes down a lot to priority, but I feel like XPS exceeds mostly in the categories of portability and style, two things that I do not value nearly as much as robustness and performance.

More than anything, the most important thing you can do is research the crap out of any option you're considering buying. I've found that Arch Linux wiki pages about laptops are quite useful, with the caveat that you have to be careful to not assume two similar models will perform similarly since that is often not the case.
Do people still fight with dependencies?

Apt or dnf or some other package manager (like yum or pacman) comes preconfigured and preinstalled on all but the most esoteric Linux distros, so unless you're doing some really esoteric stuff, if you're fighting with dependencies, I would assume something's gone wrong.

Which is to say, it still certainly possible to fall into dependency hell in this day and age, but the parent response belies a certain level of fear of installing things on Linux because of dependencies. I hear Windows still has this problem, decades later, and while Linux has it's own share of foibles, installing pre-packaged software is generally not the exciting/frustrating part. (Which Docker has made even easier!)

Earth's GPS satellites use earthward facing directional antennas, and even on Earth the signal is several dB below the noise floor, so our receivers have to use process gain to actually get anything useful out of them.

Mars is fifty million kilometers away. A GPS reliever on Mars looking for Earth satellites wouldn't be able to hear anything.

Right tool for the right job. Is K8s too complicated? For some use cases it is.

They probably should do a better job of discouraging certain use cases, but calling their elevator pitch “bullshit” is hyperbolic.

There are exceptions to every rule, but a good rule of thumb is cluster size. If you’re managing less than 25 servers than K8s is probably over kill. As you start to creep north of 40 servers K8s really starts to shine. The other place K8s really shines is dynamic load. I manage anywhere from 600-1000 16Gb VMs, I can’t imagine doing it without K8s.

If cluster size isn’t a good rule of thumb then application architectur probably is. If no one person in you company has a complete mental model of the application architecture or it is impossible because it is so complex, again container orchestration might be a good way to go.

Final point:
If you’re struggling with K8s swallow your pride and buy a managed solution, then learn as you go.

I think there is an important lesson in the approach to science that we see in the social sciences. Coming from a technical background we approach science, and data, as being the fundamental way of discover truth, but with humans there are often more than one truth.

We’ve seen the effect of it in management over the past 25 years. Today a good manager is expected to approach a team, not by instructing them in what to do and when to do it, but rather by creating a shared meaning through group conversation. It’s more important when you manage people who produce by thinking and being creative, but even at the factory line, this softer approach is proving useful.

We haven’t yet applied this to big data. I’m often sold ML as the ability to predict the future, and to some extend that is true. If I look at all the alcoholic families in my municipality and compare their case history with big data gathered on a national level, I’ll certainly be able to predict how many of their children we’ll need to remove. I just can’t predict which ones because determinism doesn’t actually work on something that complex.

The more data we have the less we understand about causality, something I’ve learned from history. If you look at the Roman Empire without digging into it, chosing Christianity seem obvious, but if you really get all the data on their options and then try to figure out why they did like they did, you’ll have no clue. Another example is online advertising, I read a news paper that I’ve never seen a single add for, and I see a lot of adds for news papers. I’m often called by news paper salesmen as well, but not for the one I read. This is because it doesn’t suit my elaborate online profile. My profile tells the add agencies what I should read, but it doesn’t tell them why, and the difference is failing them.

If we really want ML and big data to be truely useful, I think we need to learn from the social sciences, because they work much more with the complicated science behind the why.

I'm also running a t450, albeit w/ only 16gb ram and a 500gb ssd. Fan noise is not bad, certainly not loud enough to be distracting. I purchased mine refurb through Amazon for the 6 month warranty, but didn't need to use it. Wifi works great under Debian, but I could not get the Bluetooth card to work reliably. I replaced it with a card designed for the t430, but it wasn't all that easy. I would advise just using a USB Bluetooth adapter.

The only other complaint I have is that palm rejection for the track pad is poor, I eventually disabled the track pad entirely. I prefer the track point anyway, but I know a lot of people hate using them. Keyboard is excellent, IMO better than a MacBook. I would be curious, perhaps the OP used 2 500gb SSDs, you can get drive caddys to replace the DVD drive (I kept it, as I still need to read disks relatively often).

Is there a link to the tweet where he asked "what did you benefit from using K8?"
If you have enough time, a single satellite is enough, provided it's not in a geostationary orbit. My understanding is that this is part of the initial location of landers, but that once they're located there's no point, since it's easier to just optically determine how you moved.

On Earth, similar systems were used for the TRANSIT satellites, and the Cospas-SARSat program. The latter is really cool, as it used weather satellites in low earth orbit to find a person in distress, using a cheap transmitter that's placed on a plane, boat, or very famously, Richard Branson's watch.

The way it works is that the device transmits a very stable frequency. (Perhaps modulated by the identity of the person in trouble part of the time.) As the satellite passes by, it relays the signal to the ground in a way that preserves the doppler shift. When you know the position of the satellite and the doppler shift, you can know the closest point and the distance from it.

After a few passes of your one satellite (or multiple satellites, if you have them), you can get a location that's good enough to start search and rescue.

Of course, time has passed since this was designed in the 70s and early 80s, and now GPS has fallen in price to the point where it's everywhere. So now, the devices send GPS coordinates with the identity info.
> A normal man burns about 2,500 calories in a day. We burn between 7,000 to 9,000.

This kind of thing is fascinating to me. It reminds me of the guy [1] who took 64,000 extra calories of olive oil along on his tiny-yacht trip across the Atlantic, because it's so dense in calories. Or the fact that on the day a climber summits Everest, they'll burn around 20,000 calories. That's almost 40 McDonald's Big Macs worth of energy.
