> I actually do not understand why I would use Racket

You don't HAVE to.

But if you are interested, maybe this would help:

EDIT: Also, if you want a look at the dialects, check out the comic here: http://landoflisp.com/

Be advised that it is extremely difficult to "sell" Lisp and related languages to someone that hasn't bought the idea yet. No-one seems to have found a winning formula. All people see are the parentheses (although, for some reason, they don't see the ocean of []{}(); in other languages).

The normal experience is: you get tired of hearing about all those people preaching about Lisp(or Scheme) and decide to see for yourself. You take the plunge. You slave away at a book or two (or tutorials) trying to grasp the language. And then, at some point, it all just "clicks" into place and you see the light! That's what's its all about!

But then you start trying to explain it to other people... and you have exactly the same problem. All those features you now know about and can't live without? They are either difficult to explain without explaining more concepts, or they just don't see the value compared to what they are used to. "What do you mean, code is data? Code is not data, I use JSON for that."

Which is understandable. After all, if you are writing Scheme, you can easily see the value. You know how Java can spend years (and sometimes over a decade, see lambda) to get a new language feature? Well, with very few exceptions, you can do it yourself. You know 'for each'? A Scheme(or lisp) programmer could solve that in 5 minutes with a macro. But you can't, because you are not a Lisp programmer yet.

Similarly you probably see no problem at all with having YAML with a C program and maybe a scripting language too. Whereas a Lisp programmer would see that as a waste and just want to use S-Expressions for everything. Sometimes including HTML and CSS representation. And maybe more.

But there's an opportunity cost. Up to you if you want to pay for that.

What convinced me and I found it to be true: Lisp or Scheme (and I guess Haskell) _will_ make you a better programmer even if you don't end up using them in your day to day. It will expose you to concepts that you may not be familiar with - or may not had the opportunity to practice.

This is, again, subjective. Up to you. All programming languages are Turing-complete anyway.

I think the point is more that this kind of tech could be scaled up to make commercial airliners more fuel efficient too?
18 months, lol. His wife must be a saint.
I think this airplane is pressurized, flies very high and has a big turbocharger. And it has a diesel engine, so the MPG means a different thing - diesel is denser.

It's optimized differently to the experimentals, and it's more useful commercially. Flying high avoids a lot of weather issues. You don't have to cancel flights because of weather.

The drag from the streamlined shape is very low. It's just a textbook minimum drag shape.

The cruise speed advertised does seem high still.
I think it's interesting to learn what the objections were to the 19th amendment.
The last flight I was on had the window shutters down and lights off almost the entire flight.
Good point. There are other proctoring services that offer a human proctor. So, at one level, we would be competing with them.

But, more importantly, we tell our teachers that they should think of AutoProctor as more of a preventive tool. Just knowing that they are being monitored means that students are much less likely to cheat. Teachers tell us that student grades have dropped significantly since they started using AutoProctor. So, at least as of now, it seems to be working.

Another area we would have to worry about with a human reviewing the evidence is the Privacy. For now, only the algorithm and the kid's teachers have access to the data. Opening it up to third-party contractors would mean having to deal with all the issues that brings along.
>which makes rejection of their "validity" during activation a possibility (assuming Microsoft finds out, of course).

AFAIK Microsoft doesn't revoke existing activations, so you should be fine unless you need to reinstall. If you dont want that risk, a locally hosted kms server (running in a VM for maximum security) achives the same thing.

FWIW there is no official category 6, as 5 is deemed as essentially total destruction and there isn't much need for a 6. It's a topic of debate however.

Strictly speaking, there is nothing particular to Flash that precludes JIT compilation. In fact, AS3 code runs on a VM specifically built with JIT in mind. AS1/2 code does not, but that could be remedied with shittons of guard statements like modern JavaScript VMs have.

Teachers unions are only great for bad teachers; for good teachers they are at best grossly inadequate (see klyrs's response), and often outright harmful (for much the same reasons they're harmful to teaching).
Software version control by users is going the way of ham radio and people who repair their own cars. Not completely extinct, but such a small set of technically capable people that in practice it doesn't matter.

Real users don't know and don't care about software versions. They want computing experiences that "just work". They don't care or know about where the software runs, if there is telemetry, what the underlying format of the data is, etc. The article starts off with nice goals around automatic updates being user centric. But the list of requirements becomes absurd and only important to 1% of tech savvy users (formats, reverts, plugins, commercial messages, other software, telemetry, and multiple versions of UI are great if your users are software developers or IT, otherwise they are a waste of time & effort).
Although probably not the majority, many experimental aircraft do use car engines. I'm building a Zenith 750 kit aircraft and installing an engine from a company called Aeromomentum who convert Suzuki engines for use in light aircraft. The model I have installed is a 117HP engine originally designed for use as boat outboard motor. A sibling comment mentions that car engines aren't designed to operate continuously at high power. Outboards are. And there are benefits to using highly developed and tested engines vs traditional aircraft engines - efficiency being the most obvious.
There is very little to tell...

> It looks like the Yak-152 mentioned elsewhere in the thread can do about 14 mpg if wikipedia & my math is right.

Isn't the MPG highly dependent on what it's paired with? You can't expect a Honda Civic to hit it's stated MPG either if you overload the car or tow something, but if you replace a lot of parts with lighter equivalents (or put the engine in a lighter car) you would expect it to get a higher MPG.

One of the major points of this plane is that it's supposed to be extremely aerodynamic.
Well, at least it's clear that they have no competition in piston powered niche because all pressurised piston aircrafts died out. Any remote equivalents are dual engine planes.

This is an area where iOS sucks. Having faced some undesirable consequences in the past from greedy and/or downright malicious developers, I don’t have automatic updates turned on for apps.

But what makes things worse is that iOS doesn’t provide a way for a user to downgrade an app to a previous version. Since syncing app binaries to computers was also long removed (from iOS 9), the only special version of iTunes (12.6) to support the management of app sync not being updated, and Apple Configurator being messy for long, even users with a computer are left with no way to deal with these problems.

What Apple should do for iOS (and also Mac App Store), which I doubt it won’t until there’s an alternative store, is allow users to downgrade apps at least one or two versions right from the App Store. Put it in a place that’s not an “accidentally downgrade and shoot yourself in the foot”. Make a backup of the app data before any upgrade to facilitate a smoother downgrade.

Yep, absolutely. These constraints probably yield nothing in return. We have take compromise in some of these.
Big if true. The claimed performance on this is wild, especially since the pusher propeller configuration is usually less efficient than the puller configuration and its top speed is up there with the fastest piston engine aircraft (which are designed for speed not fuel efficiency).
WTF? that is ridiculous. I might drop Firefox over this.

That might sound crazy (FTP is an ancient protocol), but I spend a lot of time scouring FTP servers for old technical reports. Mozilla can't just wish FTP away.
While the shape might work well for drag, looks matter, especially with private aviation. This thing just doesn't look very sleek or impressive.

Cost to repair and insurance is also a very significant part of the cost, so if this is difficult to land or costly to repair, it won't be very popular.
Great to have such upperclassmen as role models as a student.

No one is forcing anyone to install an app store. But this logic you are already being forced to switch to Android and install a third-party app store for applications that aren't allowed on the Apple App Store or Google Play. The reality is that you aren't being forced to do that today and won't be if you can install software without approval from Apple in iOS.
Bandcamp, Patreon works well. No idea if it would work for something like Taylor Swift, but it absolutely works for smaller artists.

Even the most technologically lay person can "pirate" music. Most people I know just listen to music on youtube. Rarely if ever do profits from listening to small artists on youtube actually reach them. So, in effect, the product is easily acquired for free and there is no practical incentive to buy the product.

Yet indie artists still sustain themselves through sites like bandcamp, where devoted users can pay what they think the song/album is worth. I do so in the hope that they will create more works that I enjoy. That's the business model.
>For a lot of people, a home lab isn't just to provide themselves a service, they actively enjoy the setup and management.

It's probably more non-Japanese would pronounce the /l/ so differently that it would change the way the name sounds enough to be jarring to the individual who bears the name. That'd be a straight pain in the ass.
I don't know much about aircraft engines, but in fact straight-6 engines are inherently balanced, and a V12 is fundamentally two straight sixes, so at least in theory it would be quite possible to stop using one bank of cylinders if some of their cylinders suffered some form of non-catastrophic failure.
Good to know. Also, I never knew about kms servers; TIL.

マンコビッチ == MA-N-KO-BI-CCHI

manko is slang for vagina. bicchi is borrowed from English "bitch", but is used more like English "slut"

That said, those Russians could've used ヴィッチ WI-CCHI, such as in https://ja.wikipedia.org/wiki/%E3%82%B8%E3%83%A7%E3%83%B3%E3... So why does Mankovich use BI but Markovich uses WI ? Because expecting katakana spellings to make sense is already too much to ask for, let along expecting them to be consistent.

(Bonus: sandwich uses neither BI nor WI. It uses I. SA-N-DO-I-CCHI)

Don't force updates on people. For the ones who want to update asap they should be able to do so. I prefer to make sure a major update is not going to fuck my system then I will update as well, it's happened to me before multiple times and I am forever hesitant about this. It's also happened to me to get featured removed when updating so if something is working allright I will hesitate updating for a while.
I’ve been reading Lem’s work lately but haven’t gotten to this one. Do you recommend it?
Great concept, and not a criticism, but a bit of an anecdote

For Chinese-English it suggested "Lee", which as far as I know (my Cantonese and Mandarin aren't that great) is typically the Cantonese anglicisation of 李 (Mandarin Pinyin for this is Li)

My given English name is "Lee" and this actually causes no end of confusion in both Hong Kong and China, as it's typically used as surname - in fact, when I attempted to use 李 or even 李李 (which is what my Chinese grandmother in law calls me) as a first name on a visa that required a Chinese name to be added - they wouldn't allow it!

If anything - it illustrates why this is such a tough problem to crack!

To be clear, I'm no stranger to Lisps. I use Clojure a ton for personal stuff and on occasion have found ways to sneak it in to production.

The difference there is that Clojure isn't responsible for giving a wide enough ecosystem to justify investment, it just yoinks it from Java.

Racket doesn't have that ecosystem and probably never will. Macros on the level of common lisp and clojure are already found in those places. Racket gives, and seems to base it's pitch around, a far more flexible hammer than classic lisp macros.

But it doesn't do anything to offset the downsides of a small community or justify why that more powerful "actual mini language" level DSL is something to care about.

I am well aware of how macros can let you add your own language features and conveniences specific to your project. Homoiconicity is an all around neat property to have.

I'm just not buying a "beating the averages" style "you just see it as blub" explanation either. Mini languages do have niche uses. I acknowledge that. ANTLR wouldn't have users if they didn't. It's just not something I think is worth writing home about.
Router =/= Firewall.

If you are planning to host stuff, or even just to protect your own things, you better get something like Sonicwall or similar.

At my home I have a sonicwall, synology nas, 2 dell servers, power supplies. Not in a single closet though. To me, the server security is far more important than the looks. Spend the most money on firewall, rest is just for looks. Patch panel for home setup sounds excessive because I am not going to run all my cables thru my garage. Have individual switches in every room if you want. Most living spaces need only one or two ethernet cables, rest of the devices can be wifi easily.

I agree, Apple's approach forces one kind of value capture through in-app purchases, then they do a value capture on that value capture with the 30% take.

I'm paraphrasing Byrne Hobart here, but if they beefed up their App Store discoverability and had proper search functionality and a self-serve ad engine like Alibaba, their revenue model would reflect demand and then, finally, the Ubers and Facebooks would have to start paying significant amounts for all the free App Store support they've had this entire time.

The fact that digital content services like Spotify are expected to subsidise other companies with different business models like Facebook or Uber is indefensible IMO.
> I still wonder why so many people buy devices, where the only software you could run has to be approved by the manufacturer.

Because most of them don't really care until it directly impacts them, and because Apple spends a huge amount of money on their marketing.
I feel you’re missing the point here. Many power users opt to use the keyboard as the primary way of interfacing with the computer, and any change to that interface is highly disruptive and causes huge losses in workflow efficiency. This is the real complaint about UI changes - they ruin efficiency.

Using the keyboard is much more efficient that using the mouse, as the mouse is an imprecise input device - it requires a feedback loop to operate (you move the mouse, see where it is, continue to move it, observe again, etc, until you move it over the item you want). A keyboard is on or off - :wq does exactly two things extremely quickly - three keystrokes and you’ve saved and exited from a text editor. You can do this faster than the time it takes to move your hand to the mouse, let alone begin to move it.

All of that helps, but a pilot flying an unpressurized experimental can still get up to 17.5k' VFR on oxygen. Assuming the Celera cruises around FL250, you're talking the difference between ~300KTAS and ~350 KTAS at 200 KIAS. I'd be shocked if they cruise much above FL300, regardless of how high their service ceiling proves to be--for anything other than a really long-distance flight, they'll spend too much time climbing to altitude for it to be worth the effort.
> Edison was a major douche bag, an obvious sociopath, which sort of overshadows what he actually invented, which actually number in the low double digits

This is some sort of urban legend/myth that came about sometime in the early 2000s. Probably due to the Oatmeal.

Edison was not a sociopath. Specifically with respect to Dally, Edison kept Dally on the payroll even when he was too sick to work, and IIRC personally paid out Dally's immediate family a coninuing pension after Dally's death. For the era around 1900 that was unheard of, and at the very least, evidence of humanity that you don't seem to be willing to admit.
