Motion control is control of actuators, like motors for example. Open loop means driving the motor with no feedback source. Closed loop, alternatively, means using a feedback source like an encoder or other sensors to measure the position or velocity of the motor, and then using software that monitors that sensor and adjusts the control parameters to ensure that the desired position, velocity, and/or acceleration is achieved. This is referred to as “closing the loop” because you have the controller going to the motor as one half of the loop, and the encoder going back to the controller (and the control system code) as the other half of the loop.

Precise motion control often uses control loops (the loop of code that checks the sensor and adjusts the output) that run at 20 kilohertz, 40 kilohertz, or higher. Since the control loop is a bunch of lines of code, this means you want to execute a bunch of lines of code repeatedly at this high rate of speed. For example on an 8Mhz micro controller clock running a 40 kilohertz loop, there’s only enough time to run 200 instructions per loop! (8Mhz/40kHz=200) 200 instructions isn’t a lot, so it would be tough to run a complex motion control loop in that space. And if you want to run multiple control loops to control multiple motors - forget it.

The teensy 32 bit micro controllers are a lot faster - I see a 72mhz and 180mhz option. Either of those would be solid for motion control. However if you want to control multiple motors and possibly perform some other functions, such as computing motion commands from G code in the case of a 3D printer control board, you need all the speed you can get. In that case, these new boards offer plenty of clock speed to play with!
He did it by exploding the deficit (bunker busting tax cuts). Basically taking money from America's children to give to America's adults, who are too miseducated to realise.

I think the article strayed a bit far into metaphor, but the core story is about the red queen hypothesis.

The red queen hypothesis is that organisms adapt and change in response to an ever-changing background environment, just to maintain the status-quo. The changes ripple out, causing all neighboring organisms to adopt changes as well, to try and maintain their relative position in the environment. The name "red queen" comes from Lewis Carroll's Looking Glass, "Alice finds herself running faster and faster but saying in the same place. ... 'Now, here, you see, it takes all the running you can do, to keep in the same place.'"

How this relates to bananas is that reproduction is one of the ways organisms adopt changes to themselves (new DNA). The gros micheal bananas and cavendish bananas do not reproduce, they are all clones. As a result, all of the bananas are a monoculture which allows pathogens to spread quickly and destroy them. New bananas are likely to have the same problem, unless they reproduce and are not clones.

What I find more interesting is that similar problems occur in computing systems, where many datacenters or computing environments (hospitals, large enterprise offices) are running all the same or nearly same operating systems. The fast spread of worms and viruses are usually because the same exploit works everywhere, due to the monoculture.
I would think that IR sensors would be a natural choice,
more for ‘lost child’ or ‘injured hiker’ than for
the simpler ‘lost hiker’ scenario. One of the SAR
challenges for lost children is that they might too
frightened to leap up and wave their arms at searchers,
either human or robotic. Calling a lost child by name helps,
but IR seems like a natural choice - is there a weight,
battery, or cost downside?

Oh sorry, you are probably right there. I don't know the US system in detail and from a quick search, it looked like ch.7 would be the same stuff I've had experience with in Germany.
I agree that sass enables nice readable BEM, but I don't really think that BEM makes markup any easier to read than something like tailwind.

If you're into knowing where your class came from, it seems tailwind would be even better for you because now you have access directly to your styles right there in your markup. Skip the class step altogether!
> That's pretty solid, and far from "inconclusive."

It's literally what he said: "inconclusive, needs more study".
> Well it’s not always that the darling TL sucks

While I've definitely seen instances of the darling being a TL, my biggest issue is when its an individual contributor. I've had to deal with cases where the company's "ninja" was some dude who just hid in a corner pumping shitty code 18 hours a day, ignoring all pagers, requests for help, his teammates, or even his own TL. But he shipped software that kind of sortoff worked (well, as long as his teammates handled every pager notification that came every time it failed). Management loved him because of his "productivity" and hated how everyone else was so slow (because they were deleting with the fallout of his crap).

It was awful.
> From CIA, and TSA, to your local police department, everybody would have jumped all over it.

If CIA had it, you wouldn't hear about it. I don't see any reason why these countries couldn't pilot it for their border security before TSA, though.

FWIW, polygraphs are still used for security clearance screening. So, they are at least accurate enough for that use. They get a bad rep because they aren't admissible in court, but it's not like they have zero correlation to truth telling. They are still quite accurate.
And they're going live? You've done work? Haven't been paid? Don't have an actual job position? Contract?

Looks to me like you're being manipulated, or taken advantage of, or they're just really naive. Something like that.

The other question I have is, can you take them live and have it work?

And can you keep it working?

Once you have the answer to those things, very politely tell them what you will do, what you require them, and then don't do another thing until that's agreed to and happens.

They've got a lot of problems, and if you ask me they're looking for a person to blame about those problems. Looks like it's you.

Did you keep a log of your activities?

I suggest you get that polished up and ready to use.

Somewhat fraudulent? Purposefully misleading?
This view assumes that news that cultivates conflict and dwells on catastrophe is the natural way of things. Every news source chooses what to cover, and most of them currently choose in a manner to maximize viewership.

It's important to know that bad things are happening in the world, but there's a big difference between hearing that a number of murders happened and reading an hour long story about each individual murder.

Whenever we stay with the in-laws and watch a lot of local news, I am always blown away both by how negative it is, and how uninformative it is.

I think we could replace a lot of news with news from 10 years ago and no one would ever know the difference because almost none of the news affects them personally, but they carry around anxiety with them constantly because they learned implicitly from the news that the world is a scary place. That seems at least as much like propaganda as this.
Well, let's back up. Lie detection is not completely unsolved. Polygraphs are used extensively by security services for clearance screening. They are reasonably good barometers of truth telling. They are not good enough to be admissible in court, but that doesn't mean they have no correlation to the truth.

Even if all this "AI" does is match the quality of a polygraph, it is probably extremely useful in screening people rapidly at the border.

The rich pay most of the taxes, therefore they will "benefit" most from tax cuts, if you define "benefit" as "keeping your own money." How can someone who pays no or little income tax get a huge benefit from a tax cut?

> The polite open secret of espionage is that spying on your allies isn't just normal, it's part and parcel of basic modern statecraft.

And the corollary to the fact that spying on all of your enemies and all of your friends is considered a basic necessity for modern states: when political actors start press releasing accusations of spying, the aim is generally the manipulation of public opinion, not actual concern.

> There's really no need to suspect a commercial conspiracy when normal diplomacy is sufficient to explain this kind of thing.

I don't know that the two are particularly distinguishable.

NixOS is difficult to start out with, and great after that :p.

Started using it recently for work and it has been reliable thus far. The only issue that I've had was when upgrade to Mojave where a patch was needed. But to do this you clone the nixpkgs repo (of package descriptions), cherry pick the fix, point the package manager to the repo, and it continues to work.

One can create docker images from the machine definitions, so the target need not be nixos, but anything that runs docker.

But if you're not the type of person to pull through difficulties then this distro is not for you (yet).

The iPhone X, which is the fastest phone I can think of, gets around 500-600 gigaflops which would put it just off the Top 500 list in 2004. If we multiply by 30 for 15 Tflop/s, that's the bottom of the Top500 in 2009. Last year the bottom was 400-500 Tflop/s, which is about 1,000 iPhone X's. I mean you don't have to be in the top 500 to be a supercomputer, but I would expect it to be several hundred and not around 30.
I think that faith in the United State's economy has gone up as our administration, for better or for worse, has taken a hardline stance on "America First".

Both are federated platforms based on open protocols, capable of being self-hosted.

Feature-wise, Mastodon is a microblogging platform, defaulting to 500 characters per post, and supporting hashtags, images, and video, as well as lists and blocking/muting capabilities.

Diaspora (and the related Friendica and Hubzilla) are social-graph posting platforms, with Markdown-based formatted posts of significant length,[1] organised around Aspects (similar to G+ Circles),[2] and hashtag-based interest seaarch/streams. Images and video supported, multiple Notifications types.

Friendica and Hubzilla add groups and other features, as well as more robust blocking (a distinct weakness of Diaspora).

The core issue is that it is too hard to update the full .NET Framework without making breaking changes in this Operating System component. As actually mentioned by David Fowler, if there are missing API that are required in .NET Core, requests for them can be made.

I cannot find the comment from @terrajobst in Github anymore but it states that it is simply not possible to port some of the breaking changes to the .NET framework (because they are breaking changes in the CLR, and maintaining a third CLR version (2.0, 4.0, vnext) is very hard because of a number of shared components used).

edit: It appears some comments have been deleted, luckily we have still mail notifications from Github.

> > Do what you promised: make .NET Framework a stable framework that evolves slower instead of a dead end for the ones who trusted you when migrating to ASP.NET Core.

> That still makes the assumption that .NET Framework will eventually get all features .NET Core has, but with a time delay. We learned that's simply not realistic. We can either decide not to innovate drastically in .NET Core or accept the engineering reality that a good chunk of the new features will never make it back to .NET Framework. We believe that we serve our customers best to preserve .NET Framework's core value prop (a mature & rich development platform) while also allowing customers to exploit new capabilities on .NET Core. Moving forward, I'd expect that we'll be more willing to innovate in areas that require runtime, library, and language changes like we did for Span<T>. While these things are costly, they also allow us to change the way people can write code. A good example of this is default implementations of interfaces, the ability to author generic code involving arithmetic, being able to use hardware intrinsics etc. And those features are likely exactly the kind we're not going to backport to .NET Framework due to risk.

And later on:

> > What prevents you from introducing a new side-by-side .NET Framework version (let's say .NET Framework 5) that includes those "risky" changes? Again, it's not a technical issue.

> What makes you think it's not a technical issue? Shipping side-by-side versions of .NET Framework isn't a workable solution. First of all, it's fairly expensive due to the fact that it's an OS component and thus needs to be serviced. You have no idea how complex our branching/servicing/patching strategy for .NET Framework 3.5 and 4.x is. Adding a 3rd one is close to impractical. Secondly, just doing that also has risks, as we need to make changes to activation in order so select the correct runtime for things like COM activated managed components. And that begs the question of whether or not we support in-proc side-by-side as well and with how many combinations. It's not a simple task and not free of risk either.
It's a really hard problem. It costs over $100m to build and launch a spacecraft. Then the spacecraft has to catch up to the piece of junk, then do something to deal with the junk. We don't know what exactly it would do to deal with the junk.

Then the spacecraft would have to catch up to another piece of junk. That's hard because it's expensive in terms of fuel to change orbit. Thus the spacecraft would only be able to deal with a very limited number of pieces of junk before it ran out of fuel and became junk itself.

So, it would cost $millions per piece of junk. With hundreds of thousands now and millions in a Kessler scenarios it would be fiendishly expensive.

Partly correct.

If you try to measure Trump by some conventional, objective-reality based means, he is IMO, probably the worst president America's ever had.

But people didn't vote for him based on such reasons and his supporters don't judge him on such metrics. Trump is a subjective feeling and he makes his base feel pretty great, so...
I am curious, how could the market efficiently avoid the continued increase in atmospheric CO2 without government interventions? Isn't the continued use of incredibly cheap energy sources like oil too tempting?

"Helped" is a loaded word since everyone has a different opinion of what helped is.

I'm not a big fan of Trump, but I do have to admit he is delivering on what he said he'd do. Pass tax reform, curtail immigration, go up against China in terms of trade, get conservative judges on the Supreme Court, start the peace process with North Korea.

A lot of people may hate him, but he is getting a lot more stuff done than past presidents.
Beyond the fact that I don't really believe Wil is entirely innocent in his complaints, he simply had to change instances.

You can't handle the cognitive load of attaching a unique identifier to your account? You don't need to pick an airline or game credit cards - just sign up next time you book a flight with a major airline and you will build up points in the background.
I was with you until:

> But I guess this is boring by comparison to imagining that a historical financial center only functions through ill-gotten commercial intelligence.

Nobody said anything about "only functioning because..."

The entire basis for your position seems to be that an intelligence apparatus can only do exactly one thing at a time. It can either be for diplomatic reasons OR commercial spying, not both...

In reality governments extract as much value out of the intelligence networks and collected information as they can. If the collected information is going to help a domestic business interest against a foreign one (e.g. contract negotiations, mergers, sales, etc) you can bet your butt that tips will be supplied.

You really think that the US government doesn't routinely "tip" off Boeing and several European countries Airbus?

Countries look out for their own self interests beyond anything else. Expecting that they'll only do so some of the time rather than all of the time, seems like an opinion based more around how you'd wish a country to act morally, rather than the reality on the ground.
