My guess from having formerly been married to a chemist is that machine-based chemistry is one of the most difficult areas of science. Chemistry is still equal parts art and science in that the techniques that will give accurate scientific results depend greatly on the types of things being measured for. For detecting a particular substance, there may or may not be a cheap or viable detecting device that could be built, depending on whether that thing is normally detected by chromatography, reaction with something else, spectroscopy, etc. For example, carbon monoxide detectors are great and cheap. But I think it's probably just really case by case. Chemistry is just super hard to generalize or systematize. I used to ask her why they don't have Star Trek tricorder type devices yet that can universally analyze substances, and that was more or less her answer.

Edit: for the difficulty of machine chemistry, see also the Theranos debacle.
Persistence. Set a low goal of 10 pages per day or 20 minutes or something really really achievable. Make sure you do at least that much per day. All the clever tricks in the world are worthless if you aren't putting in the time.
Wet clothes ... fail to insulate

Choosing the right clothes can help mitigate this detail. Wool, flannel and sometimes knits can keep you warm while wet.

I have no clue what kind of knits do so. I just know I had a cotton sweater once that was insulating while wet.
That's a future in which I would buy a $1000 Apple phone. And I think the tech is all there for Apple to do it.
Grady Booch on the Future of AI
I traveled for a year with not just my ~home, but my entire OS, settings,and applications all on a portable USB flash drive.[1] The data was backed up in the cloud and the drive encrypted. If I justed need to review a file, I had cloud access and viewers on my phone. When I needed to do any real work, all I had to do was plug my flash drive into any PC with a USB port.

A high quality flash drive[2] boots up instantly and loads apps instantly. I can't work on a 3" screen and don't want to carry around anything any bigger. So for me this is a better solution than a docking station for my phone.

A sustainable colony on earth would be a good pilot
I spoke to one of the project engineers at JPL’s Open House last year. He said the only planned mission for this unit is proof of concept. If they can make it fly on Mars they will be sending a bigger one with larger batteries and more instrumentation on a later mission. He said their constraint is his team has received a small allocation of antenna time during the overall mission. The 2020 Rover ops get priority.

I imagine based on past missions, probably after all objectives are achieved and time on the array is available, they’ll get creative and push the chopper a little more.
I had a hard time with IOCP and eventuall ditched it because I didn't find a way to avoid creating a separate read buffer for each and every handle.

Suppose I want to watch 10K connections, or files, or such. 4K should be a reasonable read buffer size. Do I really need to spend 40M of memory just to read from the handles simultaneously?
Crumpler Dry Red N5. Expandable, easy to clean, robust, with small features that I like a lot.
It has been serving me for 6 years and the only sign of its age is slight wear-off of the top handle. This particular model is discontinued, but they have Mantra which looks similar to N5.
A bit too legion of Doom in retrospect.

But you would get to heavily influence what contractors and vendors the company works with are good vectors.

As well as partnership and integrations.
This is best complemented with a multiserver, microkernel architecture. With an IOMMU, and with near everything including drivers running in userspace, all of this can be achieved:

https://en.wikipedia.org/wiki/MINIX_3#Reliability_policies

With a monolithic kernel such as Linux, the reliability benefits of running some drivers in userspace are negligible, as the TCB is still millions of LoCs with no proofs.

Fuchsia, Genode and HelenOS are relatively active, promising open source operating systems with a microkernel, multi-server architecture and drivers running as unprivileged processes.
It’s probably just that the dogs can detect a problem and are barking out of empathetic concern or fear (if not trained)
Good point which I forgot to mention in the article.

There are not a Linodes or Digital Oceans in Iceland so it’s definitely more expensive. I think it’s safe to say it’s almost double the price if you buy a VPS with similar specs. Check out 1984hosting.com or orangewebsite.com to figure out for yourself.
A Nose for Luxury
You just go to the executives and point out that you own 40% of the ownership, and you'd really like them to hire these couple of guys and put them on this team, and then not ask too many questions about what they're doing, or you'll use your 40% ownership to make their lives more difficult, which at 40% can easily involve ousting them personally. (See other people's comments about the difficulty of getting enough voters to actually vote to prevent a 40% stake from being the vote winner.)

The literal thing I just said isn't even that unethical; suppose you own 100% of a company, then telling it to hire someone specific and pay them this much and put them here would be fully within your rights as owner. (There's probably a legal hurdle or two to clear, but AFAIK it's nothing that will actually stop you.) How that changes ethically as your ownership stake decreases I'll leave as an exercise for the reader. What's unethical is what they'll be doing when they get there, and who else is tainted ethically depends on how much they know and what they do about it.
Swept back wings and larger intake/bypass engines does not make the airframe inherently unstable.

The fly-by-wire system has multiple redundancies and layered protection, including direct law (at least for Airbus). Fly by wire is, like you say, of course a great innovation for improved control and safety, but it's nice when the plane continues flying even during a failure, however unlikely.

I guess in the case of MCAS the software was activity working against the pilots so maybe it's more of a problem with the design of this particular system and training.
You are right of course. If nothing works anymore that is by definition most secure.
HN is a small, but not unimportant battlefield in the global information war.
Indexes in PostgreSQL: Btree
this reminds me of the time that I helped my dad migrate his data to a new imac. with somewhat low expectations, I asked him if he knew where all his important documents were on disk. to my surprise he said confidently "sure I do!". he then opened the "All My Files" link in finder. I guess in a certain sense he wasn't wrong, but I still had to spend hours disentangling the files he actually wanted from thousands of random temp files and downloads. I made him get an external drive to clone the old drive anyway, and every so often I would have to help him find something that we had missed in the first pass.

I remember wondering at the time: do windows and mac not do enough to help users organize their files, or are the cute little My Documents and Pictures folders that obscure the underlying filesystem already too much?
Nothing. I use Python for deep learning but don’t care for the language. I prefer Lisp languages, most comfortable with Common Lisp but love the ecosystem around Racket. Love Haskell but I am in a many year learning curve.
I'd recommend to use `--partial-dir=.rsync-partial` instead of `--partial`, as the latter does not prevent an incomplete transfer from looking like a complete one.
Again, you're completely right. You will get something easier to fit into your head.

Is it perhaps possible that there might be some room to question if the goal of something that fits neatly it one person's head is really the best one? For professional applications, some might opine that there could be other considerations. Certainly most of my comments about Clojure apply to any tools that work from the same mindset.

But perhaps I merely misunderstand an elegantly made point of yours - can you help me?
Presumably this effect was first noticed without any training, when dogs who'd witnessed their owners having seizures made the connection and started to get agitated when another was imminent.
Uber doesn't technically allow their drivers to carry your child alone.
So all you've really said is that this hypocrisy has been around since the 1930s.

Not putting inedible stuff in candy does make sense to me in the general case.

But frankly, so does basic gun control so what the fuck do I know.

I would also like to add I am of the personal view gun control is very much so unconstitutional. But I also don't think that wanting some basic gun control is a wrong thing. All that contradiction means is that we need to have a very careful discussion before drafting a very careful amendment.

It's pretty easy to permit the right to bare arms while still preventing the sale to anybody off the street. It won't fix everything, but it gets us a hell of the way there.

Being worried about a slippery slope is a concern, that is why I said careful amendment.
Rewrites are almost never the right call, I agree. The company knows this, but they also see how RoR has locked them in and that the web ecosystem has changed in a lot of ways that makes the RoR proposition not so great.

So they task one or two engineers to learn Go. They learn Go in one or two days, and rewrite some scripts in Go. Big success, the scripts are much faster and are statically typed. Then they decide that for a new piece of functionality they'll write it as a service. Since Ruby and Go are both officially support grpc languages, it's easy to connect them using a protobuf schema, and have the RoR app call out to Go.

Slowly over time, more new features are written as small Go services, until eventually everything in the RoR app is legacy, or can be replaced by any API gateway.

Now if the company needs to switch again, they can just rewrite individual services in a different language.
.NET and WPF are an abstraction of win32, I view it as a step in the right direction. How did .NET people cause everything to go downhill?
Actually, the UI was the best from all vendors. It was, after couple iterations, extremly slick and useful at the same time! The OS was the best probably too, but the ecosystem with apps sucked. The good thing, MS still has all that in the pocket to pull something off down the road- certainly, they must be working on something in that area.
This is the real key for me. Every day I play an instrument for at least 10 minutes, sing for at least 10 minutes, and exercise for at least 10 minutes. Sometimes guided practice, sometimes noodling, but always something.

A great mentor of mine told me that if you want people to code quickly and without so much bureaucracy, convince them they are just making V1, a toy implementation, a prototype, etc. As opposed to The Solution. I think the same thing applies with picking up new skills. Approach it as fun and it will be fun.

Cygwin just feels "heavy" when all I want is rsync. Without any package management (that I'm aware of) I can't just install rsync and whatever other dependencies it has, I have to put hunderds? more binaries on my system.
For those of you who don't work in the warehouse logistics space ProMat, which is to warehouses as CES is to home gadgets, is coming up in a couple of weeks so expect lots of warehouse robotics companies to continue making announcements.

The roboticization of manufacturing is mostly finished since factories work with identical outpus SKUs every time. Warehouses tend to have to handle a lot of different SKU but in a fairly regular way meaning that they're an environment that's pretty much ripe for robots to be entering just now. Goods to picker systems (like Kiva) have really taken off allowing robotic pickers like the one sold by us a nice ecological niche to fill. There are also companies with robotic forklifts and all sorts of other things.

I'm not entirely certain that the role these bots are performing wouldn't be better served by a large stationary robotic arm, as some other companies are working on now. It might very well be the best solution for unloading trucks?
That, and plasma active on the KDE side.

On the upside, this is still being worked on. The UBports community is still active, and KDE has been refining its plasma mobile interface. Purism's librem 5 should be convergence-capable.

Window toolkits are also being developed to help create responsive applications: Kirigami and libhandy, to name a few.

On the non-opensource front, there is also Microsoft's UWP, and samsung's DeX is showing some promise.

We're getting there, but slower than anticipated. The EOMA68 is also a promising concept, though slightly different, and more similar to what the parent describes.

Is anyone familiar with any "electronic nose" systems and what the cutting edge of them is now?

It does also fit with Apple's desire for more reasons to pay a lot for a phone. They seem to be running lower on those than they used to.
Not a rocket scientist, but I really wonder about the cost-effectiveness of this approach. Is it really more effective to do testing in prod (on another freaking planet) than to more thoroughly emulate the Martian atmosphere here first?
I don't see why this realization should be regarded as a counter argument to establishing a Mars colony. It's really really hard and a lot of problems need to be solved.

The most important thing for me is that most if not all of these problems are extremely relevant on earth and for dealing with climate change and overpopulation. Now one could say that we should then solve them for Earth first, but that's not how things work. We only have solar panels today because there wasn't any better way to power satellites. Earth makes things so easy that we won't go for >99% water reclamation, 0 waste green houses and so on.
There's quite a few diseases that can be smelled.

I think it's pretty interesting and often wonders if that's the reason some people have some kind of "sixth sense" when it comes to diseases.

A lot of tech people seem to be libertarian and don't like paying for public services that might go towards actually helping these people. In my experience people are not really that left wing in the valley when it comes to money.
Especially WPF is not an abstraction of Win32. Maybe Winforms could be called that but certainly not any of the XAML dialects.
It's just as likely that there were negative opinions created for your impression, and way people actually feel is coming to light. Disinformation cuts both ways.
> but that would require a base-station with solar or nuclear power source. I am not understanding how this drone would be effective in a mission!

We have a very good track record of sending large rovers with solar and nuclear power sources to mars. A rover would make a good mobile base station, with a helicopter for collecting samples from various places to bring to the rover's onboard lab.
There is also a linux subsystem for windows 10 which I have never used. Perhaps someone can say if that has rsync.

[ edit ] if that and cygwin are too heavy, you could request the samba team create a posix windows build of rsync. They had one long ago, but stopped supporting it. That would be a single binary. I suspect they will push back.
If it's the strength of a particular chemical signal -- like dogs can normally smell it, but it's suddenly stronger -- then that seems like it's going to make false detections very difficult. Training a machine to have an innate sense of how smell works under changing environmental conditions seems like it's going to be hard.
Bear in mind that the sense of smell is different from the other four senses in that there isn't a separate sense organ in the nose. The Olfactory bulb is actually part of the central nervous system. So to "grow a nose" you really mean "grow a brain".
Systems get better with refinement. The F35 is getting into the "mature technology" part of the progress curve now so it's naturally going to look better. It took a lot of money to get there but we're starting to see more positive results.

People are more likely to submit what they're reading if a similar post has already proven to be popular.

Overall JSF program aside, this is a fairly interesting and in depth (at least for this audience, this is probably just a high level overview to someone who works on electronic warfare technology) article on a particular subsystem so why wouldn't it be popular here?

But without saying "this is a test for Mars" such a colony will never be built. Even in Antarctica shipping in supplies once a year is just sooo much easier.

There really are too many "I know you better than you do" doctors out there. There should be a consumer panel that rates doctors according to their efforts towards a successful treatment.

Not necessarily, it was the best OS in the later revisions, but too late. Ecosystem with apps lacked behind- that's the reason it didnt succeed.
I've got a reasonably-high-end card from Chase, and I was impressed that they moved all personal information other than my name to the back. The front has only my name, the "chip," and the name of the bank and card. Which is still two more pieces of information than the Apple card.

And the back? It's a mess, and important info is being rubbed off every time I remove it from my wallet.

And the card itself, the blue-colored surface plastic is separating from the metal core at one corner, so what seemed like a nice satisfying metal card now seems cheap and disposable.

These are silly things to care about if you don't, but the fact that people do is why we have nice things.

We don't really 'see' things. Rather our eyes are just one of the means by which we correct our guesses about what's out there.
Or, maybe, humans have the olfactory capcities but these sensations are not transfered to the consious.
hahaha fair enough! :)
We have absolutely no idea what would have happened to Amazon if they prioritized profit over growth in the early years. There's no guarantee they'd be a successful company now in that alternative future. Undercutting the competition on prices to increase sales volume in the early years was key to their success.

FWIW Google Photos does exactly this. It even scans your directories and pops up a prompt "Hey, I found a new folder with images, want me to back it up?". I really wonder how this will turn out...
I've been happy with a Dakine Duel 26L. I know that's going to seem too pedestrian to some because it's pretty inexpensive, but it fit my requirements.

First, it had to be relatively compact. Specifically, it had to fit under a standard economy-class airplane seat with room for my big feet.

Second, I wanted something more vertically oriented than usual. Most backpacks have multiple pockets in a "sandwich" configuration, so everything slumps into the bottom of each one and the top remains completely slack. I hate that. Having two decently sized outer pockets in an over/under configuration really helps. The straps (it's meant to be a skateboard pack) are occasionally handy to hold a jacket or hoodie instead of stuffing it inside.

It's not as weatherproof as some, certainly not as stylish, but it has survived a dozen week-long coast-to-coast trips and still seems barely worn. I looked at a lot of camera and other packs that might satisfy my preference for verticality even better, but for one third the price this one has done just fine.
Several such stories imply that if we are ever able to build machines that can smell things, we might open up an entirely new world of diagnostic tools for medical sciences. Though I am not sure how well we understand how smell works and I recently read somewhere that human smell system might use quantum tunneling so I would say such a system might be decades away if not more.
