It is, the tail rotor is needed because on a conventional helicopter the main rotor is spun using a torque force from the helicopter body, through the engine/gearbox, and into the rotor. On this helicopter, the force is from the rotor through the rockets to the air, there's only a tiny friction force dragging the body along with the main rotor, and it looks like that's small enough to be counteracted by the aerodynamics.
>is "rm" (pronounced "remove") really synonymous with "delete". Do I call the deleters when I want to move house. How would my first cousins once-deleted feel?

I don't think it's good to make the command name an English word. Perhaps it would make the command easier to discover, but it would also introduce certain unpredictable connotations.

For instance, if the command was called 'remove', then someone might presume that it was being 'removed,' and 'replaced,' somewhere else. 'Remove' has the connotation that you are taking something and necessarily putting it somewhere else, which is not what 'rm' does.

'delete' has less ambiguity, but I'm not confident that similar mixups wouldn't happen. It's better for the command to be something ideosyncratic so that the user goes in with no assumptions about its function.

To paraphrase Rob Pike, the command is not remove, but 'rm'. It's called 'rm' because rm is what it does.

More mature users means different bullshit. The flight sim community is an example of one I'm involved in which has many forums with older users that grew out of 90s forums or even older BBSes and have a large older audience.

I wouldn't call those forums as having less bullshit than say the Reddit, which has the younger parts of the community.

As an online educator, this is the nut I’m trying to crack. Beginner stuff doesn’t interest me and advanced stuff is often so specialized you can’t really teach it. And selling to intermediate engineers is crazy hard it turns out.

Everyone thinks they can figure it out on their own and doesn’t want to be taught. Or works in areas so specialized only their teammates can help.

And you’re always fighting against a sea of $10 Udemy courses and free resources.

That said, I think it’s a crackable nut. It’s just a longer slog than beginner stuff.

This is one of the most difficult things to get when building your startup. At the beginning you have no way of getting accurate costs, and clearly, there's no one-size-fits-all approach for this.

Its just trial and error
When the engine on top of a helicopter spins the blades, they exert an equal torque force back on the body of the helicopter. In order to just spin the blades and keep the body straight, you have to cancel that torque by using a tail rotor which creates a force way back on the tail that with the length of the tail, cancels it out.

In the case of this helicopter, the force to spin the blades comes from the tips of the blades, expelling gas out the tips will push the blade tips forward, so the body doesn't push on the rotor blades at all to spin them.
Because the rotation is caused by a force at the rotor tips, so there is no torque on the aircraft. A conventional helicopter has an engine that is rotating a shaft connected to the rotor, so the engine is creating a torque on the shaft which causes the rotor to spin and then the shaft is creating an equal and opposite torque on the engine that is causing the aircraft to rotate the opposite way, which the tail rotor cancels.

I know that this is a joke

It's humor not a joke. There's deep wonderment at how much the world has changed behind it. A 16GB thumb drive holds 10,000 times more information. A floppy disk doesn't even have the most rudimentary electronics built in. You can't even turn one on.

The problematic part is "for the younger readers out there."
Leave that out and it's fine. Replace it with "Fuck, I'm old" and it's pretty good.

Technical articles are (well) technical and the author is not responsible for explaining what a floppy disk is in a world where google and wikipedia are eleven keystrokes away. The reader has to work too.

I like that.

Those four disks cost less than $1 each, and each individual one holds over one million bytes? Amazing.

They sound so useful that I bet people built whole collections of them, including devices just for organizing and protecting.

The difference is in where the torque is generated. In a traditional helicopter, the engines (mounted to the main body) generate torque to spin the main rotor. Since the body spins the rotor, by Newton's third law, the body and the rotor spin in opposite directions. Therefore, you need a tail rotor to counteract that.

With this design, the torque to spin the rotor is generated on the rotor itself, so there is no torque effect on the airframe. Note that there is still a (rotorless) tail with fins, probably to stabilize the aircraft in forward flight.

For more on this design, see https://en.wikipedia.org/wiki/Tip_jet
You can't see how that's a double edged sword though?

I buy a device, I even buy a special computer so I can build programs for the device... and now I have to pay $99/year just to comfortably run my own program on my own device? Even worse, I can't even continue to digitally interface with my own customers, people who Apple never helped me land as clients, without passing through Apple's arbitrary store rules AND paying them 30%?

That's fucking dog shit and it's going to have to change, especially given that they have 50% of the market in the US.

Ask HN: Best programming course for an absolute beginner?
A friend of mine, who has a banking background, asked me for a code/programming course recommendation. He isn't technically inclined, but I believe he's in the perfect spot to take up something new. Hence, I like to give a great recommendation, but have a hard time judging what would be a good choice for an absolute beginner.
GIFs That Explain Mathematical Concepts – IFLScience
But when the line is faint you get false negative from the machine.
A typical helicopter has a motor between the body and the blades. Imagine using a screw gun. When you go to tighten a screw, equal force is imparted back on your hand because it's using your hand to push against.

These designs have the rocket motors pushing between the blades and air. This means that the spinning main rotor is just sitting on a bearing and the rotor is not being pushed off of the main frame.

However. You still need tail control to point it the way you want and to counteract inefficiencies in the main rotor bearing, that is why their prototypes have a tail rotor. That said, it's not As needed. If you lose the tail on a normal single blade heli, you are in for one hell of a ride. On this, a little forward movement and the vertical tail of the heli is likely enough to keep it straight.
I bet if we check back in mid November, much of the information will be there.
No. If you really understand what you’re doing, which after 10 years you should, picking up a new framework or library is quick. You might not be writing the most idiomatic code after 3 days, but you’ll do fine.

That is true and I recognize the purpose of being a proficient Googler; however my concerns stem out of the idea that learning many of those skills are not taught at all or expected to be learned in situ through programming assignments.

Here are examples of what I mean:

- An undergraduate Networking/Security course may not provide practice on appropriately salting passwords. It is merely discussed as part of some larger conceptual model. Students are browbeaten in earlier courses to not simply copy/paste code they find on the internet

- Debugging practice has to come from the student's own generated code, but if they made a mistake, they already are showing they do not fully grasp the material. There have been efforts to explicitly train debugging [1] but they are still in early stages of researching their benefits.

You are so right. The market is super fragmented. And it feels like there is a new workflow tool everyday. Even I had built one similar to Kubeflow.

Finally, I think the survival of tools will come down to being able to compete on the price with leading cloud vendors.

Just like the choice of programming languages the decision would get down to your team's past experience and cost of ownership.

Completely agree on this. At least the major topic/language/framework discussed in those channels could be mentioned.
Some video games that explore the human condition and could be said to be Art with the capital A:

The Stanley Parable (deconstruction of what it is to play a game. It starts with a third person narration of your character being at work, pushing buttons all day without being quite sure why, and proceeds into multiple endings that deconstruct reality in quite creative ways that sometimes break the fourth wall)

Braid (Mario clone, but you can rewind time and there's a story line that riffs on the old Mario memes but uses them as a metaphor for the atomic bomb)

Dragon Age: Origins (DnD based game with excessively fiddly combat but a fairly massive branching story line, asking the user to make many moral choices, with outcomes ranging from mostly happy to everybody dies)

Portal I and II (notable for their sci-fi dystopian narrator GlaDOS, who is voice acted by an opera singer who plays a computer that has gone insane)

A lot of what computer games do as an art form is fundamentally different than other genres - their chief advantage is interactivity, which is something we haven't known what to do with in art very much prior to this, other than a handful of plays that break the fourth wall.

This interactivity allows for experiments in the concept of community and alternative models of fairness and social status. The reason I still would qualify these as art is that they are exploring these spaces in a non-systematic and intuitive manner rather than an academic one.

This puts MMOs at the top of the medium as an example of what games can do to explore the human condition. They can be life-consuming and addictive, but they explore alternative identities, economies, and social systems in a way and on a scale that no purely intellectual endeavor detached from real economic and political consequences has ever done before. As to what we take from this, I'm not sure other than World of Warcraft has taught me how naive libertarian economics can be given how completely a player was able to take over the entire server economy on one server by just buying low and selling high until his economic advantage was sufficient to control the market.

> There’s a very vocal group that tells you not to write in C because it’s unsafe

I get the reasoning to learn it. Just after you do learn it, stop and use something else. Unless you absolutely have to. I don't think anyone has attempted to compute the amount of money spent on buffer overflow hacks. But I'm guessing it's in the 10s to 100s of billions of dollars if you count all the viruses that took advantage of it in the past in Apache web server or Windows NT's NTFS (or sharing etc...) codebases. And that applies to C++ too.

And hey, I know that sounds extreme - but there really are situations of "unless you absolutely have to" but I wouldn't expect anyone to write a brand new queuing system or database in C or C++ anymore given the alternative languages available.
The problem with this "conversation intellectualism" it's all 30,000 feat drab cultural analysis of symptoms and no rigor to actually dissect causes. A good materialist approach might not charm at the moody cocktail party, but actually has explanatory power and proposes remedies.

If Ross Douthat thinks we've slowed technologically and modern technological gimmicks are trivial, well hahahaha, I agree, and he's just betrayed every conservative tenant.

- Space race was classic post-war consensus big goverment spending, and planning.

- Modern technologies, whether it's startups focusing on trains not plains, small powerplants not big ones, phones satellites and not wires in the ground, is entirely tech hacking around coordination failure. We've lost the ability to collaborate on the big stuff, and a lot of that is due precisely to conservationism weaponizing exiting structural failures in our governance model.

Art stagnation: well actually the popular art has been getting a lot better. Look at old music videos vs new ones, for example. Also R&B triumphing over rock as the foundation of pop means we get better rhythm and harmony, the twin pillars of syncretic music. But if high art is stagnent, well, that's clearly got to do with a the stagnation of the people on the top of the economic period with the leisure time. Nothing promotes changing tastes like changing audiences. Or blame underfunded schools and increasing in working hours for the non-rich.

Economic stagnation. Obviously wage growth decline is a proximate cause, not just a symptom (i.e. other factors might cause it or make it hard to fix, but if we could fix it it would help with the rest).

I could go on, but basically Douthat is just talking about symptoms to get along with the more literary coastal elites. It's shambolic. I'll take it more serious if he learns macroeconomics and becomes some sort of libertarian UBI-er.
There was a helicopter that used a ram jet IIRC. I guess the only problem there is you need a separate starter motor to get the rotor spinning fast enough for the ramjet to take over, but most helicopters have electric starters anyways.

On a tangent, the author has an article in the Atlantic about the increasingly strained economics of universities. Combine that with the novelty of Patreon's fundraising and it's worth pointing out the author's Patreon page. He has a very reasonable "buy me a coffee" subscription.

It's no one's fault that a chunk of society goes down the humanities PhD rabbit hole only to discover the adjunct professor job market is bonkers (some of the world's smartest [or some semblance of it] people competing intensely for almost no money).

Curious how this deals work moving training data around... If you're dataset is a few gbs moving it around is a good bit of overhead, and a decent chunk of local disk space for the host system. Probably not bad of there's a consistent task, but seems like a big problem if the tasks change often.

SAFe as I’ve seen and experienced it is a cumbersome, process-heavy system. Like most other project management systems currently in use in this industry it’s probably okay if 95% or more of the features are well-known and specified clearly. For any non-trivial software development work it’s a burden. For development touching other disciplines (e.g. statistics/ML, new product development) it’s more like an obstacle.

It really depends. For sure there are models which should be processed in the background. It is a very basic tutorial that shows how simple ML models can be used as REST API. In the tutorial I was using Random Forest trained on UCI Adult Income data set. The final model was small, and computing predictions was fast.

I would love to add more advanced part of the tutorial with background processing for large models.
I'm going to nitpick here, but RSS is a technology built on the Web, so it requires some sort of website control. So RSS podcasts require websites.
