All of the illustrations I can see appear to be just that: Illustrations. I have real trouble believing that they will be shipping an aircraft, even a hobbyist aircraft, without at least one honest-to-goodness picture of a prototype. (UPDATE: http://www.eaa.org/news/2011/2011-04-14_aero.asp has a picture of a prototype that has not been flown yet).

And manufacturing with carbon fibre is non-trivial. The bicycle industry is full of horror stories about design firms that outsourced the manufacturing and wound up (heh) shipping frames that cracked or split. It's a wonderful material, but it isn't a no-brainer. I would expect that having designed such a thing, they would need to build a succession of prototypes, followed by choosing a manufacturer very carefully, and then doing some prototypes with the manufacturer to iron out the issues involved when scaling up to production processes.

So where are the pictures of the prototypes?

And about what they call "Tech:" They. Must. Be. Joking.

Where is the discussion of the airfoils chosen or how the hull is designed for takeoff from water? What's the maximum wave height this craft can deal with before you say "Too choppy, can't fly?" What's the takeoff speed? "Runway" distance required? Stalling speed? Where is the designer bragging and boasting about the unusual wing design and what problem it solves?

This web site does NOT satisfy my sniff test.
How do I transfer my coins from one computer to another? I found digging through my application data to find the wallet.dat file is unintuitive.. along those same lines, how many less technical users have lost extremely important data because they never made a backup? Additionally what if I want one wallet so I can go to a physical store, and use my phone to pay? The shuffle seems very inefficient to me. Perhaps people could setup servers to host their own wallet... however that creates another barrier of entry to less technical users.

Look at this crazy shit: http://www.stronggames.com/bitcoin if I want to buy a game I have to somehow obtain 40 bitcoins (the markets are great for speculators, but its not 2 buttons simple for people who just want some coin) after I somehow obtain the bitcoins I need to tell them about it...

In the form that it is in today, this is a currency for geeks. Awesome? (hell yeah!) but sometimes you need to do business with non geeks, and its just not ready yet for them.
That's not inflation, though, that's just a price change...

I agree with you (and upvoted you). The reasons is simple to express emotion and obviously to get attention.

A little bit of history. I don't remember exactly when in the 90's it changed but at a certain point there were actually certain words banned from being used in domain registrations.
Not just their own chip, arguable one of the highest performance ones. At Intel, the mobile division was simply trying to keep pace with Arm with Apple always a distant dream. Later at Arm, no one had any idea what the hell Apple was doing. They pay for the ISA and that is basically as far as I ever saw the collaboration going (besides poaching top engineers).

Most interesting thing I ever saw was that they bought Intrinsity[1] to create custom EDA tools for them. There is a decent technical moat to overcome.

Every society needs rules, ways to enforce these rules, ways to teach these rules, and ways to get people to align to common objectives.

Throughout history societies have used religion as a way to do this. Every society usually had one official religion that was used in this way: ancient egyptians, ancient greece, roman empire (first a religion copied from greece, later replaced by christianity, where the center of christianity was actually moved to rome), european kingsdoms with different versions of their official christian religions, and other countries throughout the world.

It's a pretty simple mechanism: follow our rules, god sees everything, if you don't follow the rules you will be punished, i.e., go to hell, if you follow the rules you will be rewarded, i.e., go to heaven.

We do the same thing with children in the hope that they'll listen to their parents: if you are a good boy/girl you get presents from sinterklaas (santaclause), if you are bad you will be be punished. Dutch santaclaus will take the bad children to spain, which is our version of hell ;-)

Funny thing is that children around the age of 8 will be smart enough to understand that they've been lied to and that santaclaus doesn't exist, whereas with religion some adults never get to this point of enlightenment.
Here are several from a comment 2 years old,

https://www.reddit.com/r/askscience/comments/9qw3y0/do_count...

And here is a meta analysis that suggests hand washing has a significantly protective effect, while wearing masks has a protective effect just not significant,

https://www.sciencedirect.com/science/article/pii/S175543651...

Given that information it would make sense to broadly encourage hand washing over wearing masks. And that's exactly what the CDC did.

Looking at the state of things now, I see far more messaging about wearing masks than washing hands, and I'm not convinced that this has been beneficial. OTOH, maybe we were screwed either way. Some people have been determined to ignore guidelines.
Well its both sides of the political spectrum; not just limited to one side.

Actually, it's more like those who are guilty like deleting their own recordings, messages and pictures off of social media after the event is broadcasted all over the world, including the Proud Boys, BLM, Antifa and Patriot Prayer.
> Nowadays Plummer does not have to dip his toes into the waters of x86 assembly. Having enjoyed Pascal in school, he "rediscovered much of the same 'elegance and cleanliness' in C#."

I can definitely relate to that.
This seems to yeild some of the "portrait mode" effects. Seen in smart phones.
1) People are calling this an “insurrection” because it’s so directly an attack on country leadership. (Whereas the incidents you’re referencing are predominantly riots and attacks on the police.) There may be hypocrisy here, but I don’t think that word is a part of it

2) I think the major difference in the left’s eyes is that those protests were against police brutality and racism, whereas this is an attack on our democracy and an attempt to overrule a free and fair election. Motives matter

3) Invading the capital building wielding deadly weapons is (pretty objectively) more serious than attacking the outside of a single federal courthouse (not to minimize that of course)
> everyone hates the umpire.

I'd say @dang is pretty liked around here! Ups to the great umpire, keep it up. This shit is hard.
Whataboutism at it’s finest.

What do you think the establishment would have done if BLM protesters stormed congress?
These responses are over the top. The photo of the congressional office that is circulating shows a wireless Logitech keyboard and mouse, and an unlocked workstation. That tells a pretty damning story about the ambient level of security awareness in congressional offices. Congress has a very serious technology competence problem. Probably a better long term strategy to focus on that.
If I had to go back to the office I would simply work for big tech.
I managed distributed teams long before COVID. Having people meet in person a few times a year does wonders for team cohesion.

Some people handle remote communications just fine. Others were raised on a steady diet of internet flame wars and approach the screen names in their company chat the same way: As enemies to argue with every day.

Putting people in front of each other associates a real person with that screen name. Everyone starts treating each other better and working more cooperatively. The transformation is almost instant.

One important tip: Face to face meetings need to happen on regular company time as much as possible. Avoid anything on weekends or after hours as much as possible. You don’t want the team building to be an extra ask on top of their normal workload. It is their workload. Obviously flights and hotel stays must be an exception, but keep it in bounds of normal working hours as much as possible.
For everyone that complains about interacting with colleagues. I feel that this can be addressed by having managers do periodic offsite meet-ups.

However there are those people that comes to the office to talk all day, and honestly, for everyone else's productivity, it's better they work from home.
I much prefer a 4k monitor as my primary, and my laptop below it (open, as a small second screen).

Going outside, working just off the laptop, is a definite shift. It usually means less coding, but sometimes it pushes me to be productive in areas I normally neglect (documenting, planning, organizing).

To do real development, I am very dependent upon a big monitor. If I travel, I take one or rent one.

Honestly though, sometimes I just go for a walk. And often during that walk, with no screens, my brain magically sorts through some problems and gives me new insights.

If you work from home though, most people agree on dedicating some space and properly equipping it. Working always only on a laptop in a floater kind of way is something that I suspect most people cannot do with any real level of productivity.
Well, yes, I would suppose it's n^2, but with a very small constant as most e-mail clients run on computers.
I have a hard time wrapping my head around why companies are mandating 100% return to office.

I doubt it lasts, at least in software. Talented people are going to have lots of remote options making it harder to find good people willing to show up for daily cubicle warfare.

I was someone who preferred to be in the office every day prior to the pandemic. But after adjusting, I really, really like working from home. Truth is, I can't imagine I'll ever take another job that expects me to show up to an actual office everyday. I'm sure I'm not the only one.
> the blame for this lies in management and the seniors on the team

It absolutely does. Point is a lot of industries never formalized training, instead relying on osmosis across teams. That creates a--hopefully temporary--disadvantage for new hires. Again, in some fields.
The complete inability to predict anything useful[1] is a clear marker of the failure of this model though…

I custom build mine out of marine ply and scrap scaffolding pipe (a few years ago, don’t have it anymore), it was handy at times but I ended up sitting down more than I expected, basically any time I had to really focus I’d sit down.

I think it’s because I have 30 years of body memory saying programming should be done sat down, I know others who’ve used them and like them so really it comes down to trying a cheap one and see how you get on.
Why do you care how they spend your fare? You should care if you are getting a fair value for your fare.
So, if you have a main street shop, it would be ok to have detectives monitor people as they enter the store (EDIT to add: or, actually, as they're window shopping), take notes as to what they buy, surreptitiously check their ID, and then follow them home (or place a bug on their car) to find out where they live, what car they drive, etc., so that you can better understand "who my customer is and why they're not buying my product"?
Speaking to your first point I am using my laptop at my desk and portably. At my desk I use an aluminum stand that raises the computer off of the table and into a more comfortable viewing position and I connect a portable mouse and keyboard. It is totally possible to comfortably use a laptop at your desk.
I think this last point is a really good one and is something that people who haven't been on the selling side don't really appreciate - it is often difficult to decide what to charge for and how much since different customers derive different amounts of value from a product in different ways.
Nice job! It's fun. The jump is a little too slow for me though. And it's very frictionless. Awesome that this was done in html5.

Yeah I think it's important to remember that the guy is pretty busy, probably gets more than one of these kind of emails (probably on both sides) a week. Also some of the hardcore free software crowd is pretty radical and these are the kind of people he probably deals with the most thus that could shape his opinion of things.
>surround sound for headphones (defined as: HRTF implementations) don't work

I'm not trying to be an ass, but do you have any hard evidence or citations for that claim?

I have been a skeptic of the technology as well, but just 2 weeks ago I tried a demo [1] that was _very_ convincing. In short, I wore ~$30USD headphones while a device with some positional sensors was moved around my head and music played. The only sound emitted was from the drivers in the headphones, but I do not exaggerate one bit when I say that my brain was tricked into believing the sound originated from the mystery box moving around my head.

Perhaps you have some scientific reason for why in theory (or fact) it doesn't 'work' in the physical sense, but my anecdotal evidence supports that there is a way to do a 'good enough' job where the brain is successfully tricked.

I admit to feeling there's still a bit of a snake-oil salesmen aspect to this technology, but the guys at Visisonics spun off their company from research at University of Maryland. They're not just another ragtag shop implementing your last decades' positional audio algorithms. They really seem to be pushing the space forward.

One of the main concepts in physically based rendering, more than whether it uses path tracing or ray tracing or global illumination, is the notion of correctly modeled energy conservation with respect to the rendering of surfaces.

I think the greater problem is not with the standards (which I know nothing about) but with who is teaching it. I have talked to people who are elementary school teachers who know nothing about mathematics, yet they are given the task to teach it to children. They have little understanding of why the mathematics they teach is important and useful. If you don't give children a solid foundation in their formative years, they will always struggle with mathematics.
I wouldn't be threatened. One of the most poignant value propositions is about hosting.
Firstly, I think you probably mean +0.01 +0.70 +6.00

Also, when you say the +0.01 and +0.70 there, aren't you implicitly borrowing anyway? It's just "easier" borrowing -- you say that 0.09 + 0.01 = 0.10, as opposed to explicitly borrowing the 1 to the second decimal and subtracting the 9. Similarly, you say that 0.30 + 0.70 = 1.00 instead of borrowing the 1 to the first decimal.

I can see why this makes mental maths easier, but I don't see that it is any deep conceptual improvement over the borrowing. Is one of the goals of Common Core to improve mental arithmetic? If so, then this makes sense. Otherwise, unless you properly explain why the two are equivalent, and why the other method is faster, it's more like a neat sleight-of-hand trick that might leave kids slightly more confused about why it is "better" than the borrowing method.

Aaron is going to be so great. I’m actually interviewing him later today :) Quite a day!
This made me discover Apple’s Settings profiles, and how this can replace complete apps such as Cloudflare 1.1.1.1 (for the DoH part, not for wrap).

Are there any other common tricks to use settings profiles instead of apps on iOS?
Right. They are calles a Mass (or a Masskrug). While "stein" is a German word, it isn't used in German for the glasses[1]. The German term is "Krug" or "Bierkrug", or in the case of 1 liter, a Masskrug.

In the Oktoberfest time you can find bundles of a 1l can of Oktoberfest beer and the fitting Masskrug in the supermarkets. For Oktoberfest, special charges of beer are brewed. To compensate for the large servings (1 liter) it is even stronger than normal beer at about 6.5%. So the inexperienced should be careful with that, or they are going to make experiences. Been there, done that! :)

1) I would expect the name comes from "Steingut", which is a ceramic. It was traditionally used for making beer mugs, but today, mostly glass is used.
For us developers and tinkerers that like to abuse our systems every which way: I’m inclined to agree with you. For everyone else: I’m not so sure. MacOS (and iOS) has made it super simple for me to help my parents and other lesser tech literate people I know, and really hard for them to screw up (too badly.)

I bet there’s a better middle ground to be found, but I’m not yet convinced that macOS is fundamentally broken beyond repair. I’m on the fence, currently.
I am not an Apple customer myself, so I have no idea how Apple works. I assumed that the store employee could redirect her if necessary.
> I saw this app with a few friends and we jokingly clicked 'buy' thinking it was a joke, to see what would happen.

It should not be possible to buy anything this expensive with a press of a button. They should ask for additional, confirmations, even call the buyer if it's this much.

Also unconditional refund should be available for every app during at least some time after it's purchased. I actually had no idea Apple users can't return an app they don't want.
This looks super interesting, I have previously considered using the Bayesian Optimization[0] package for some work, but the ability to switch out the underlying algorithms is appealing.

Perhaps a bit of a far out question - I would be interested in using this for optimizing real-world (ie slow, expensive, noisy) processes. A caveat with this is that the work is done in batches (eg N experiments at a time). Is there a mechanism by which I could feed in my results from previous rounds and have the algorithm suggest the next N configurations that are sufficiently uncorrelated to explore promising space without bunching on top of each-other? My immediate read is that I could use the package to pick the next optimal point, but would then have to lean on a random search for the remainder of the batch?

I'm old enough to have passed through one or more rationalist phases already. Note that I love rationality, and depend on it for my bread and butter, but this doesn't earn my endorsement of any specific "rationalist" author or movement.
> The fingerprint readers work! The webcams work! Audio works! Wifi works! All with close to zero hassle (had to enable a PAM option to use the fingerprint reader with sudo, but otherwise no problems).

You're happy now, but wait until you try using the trackpads.

There's only one company in the world that cares enough about ergonomic fit and finish to make a laptop that's actually pleasant to use over long periods of time: Apple. The kinks will be worked out with the M1s and macOS in general, and then Linux will look like the joke it is by comparison again.
Cool stuff, any hybrid gives me something to think about, thanks a lot.

And PS, I'm not wedded to the complex Pathfinder rule system to any degree really. I mention it primarily for context.
If you have taken engineering at a college level you probably least bumped into a handheld HP calculator at least once.

If you have taken an introduction to the Unix/Linux shell, you most probably saw the dc command.
And just like that, the technological world takes a step backwards. It's akin to when Concorde was decommissioned; the standard way to sell streamed movies may become to have a physical copy, with all the limitations that causes. This time it's due to legal restrictions.

Whilst this change will hopefully benefit customers and help lower prices, anyone can see that this is not the optimal solution.
A bad example of mental model or visibility. Android back button.

Sometimes it takes you to the main app screen, sometimes it takes you to the previous app.

Same with multitasking. Sometimes the task will run in the background. Sometimes it will be killed. Not fun if you keep thinking that im app is still online...
There are two problems with that.

1. In practice you almost never want to load a random library that says it supports a certain interface, you will want a specific library. Notable exceptions are glibc where the interfaces are well-defined over several decades but that brings us to...

2. Few libraries implement the same exact interface. Mongrel and Unicorn have totally different interfaces. Phusion Passenger is also a web server but works in a fundamentally different way from either of them. Hpricot and Nokogiri are both XML parsers but their usage API is different.
I'm guessing people are buying into the standard anti-powerpoint rant. I don't see much value in it either. I don't particularly care whether speaker X wants to give their slides away or not. But the concept is, as usual, generating a fair amount of me-too-ism.

Oh well...
I'm in my 30's and wear a watch all the time (apart from in bed). I did go for a period (about two years) of not wearing one but it always didn't feel right. The reason for not wearing one then was because my previous one broke and I convinced myself I didn't need it due to the phone in my pocket.

I'm currently wearing the one my girlfriend got me for Christmas and, not only does it make my wrist feel better, it reminds me of her all the time which makes me feel closer to her (sorry for the sloppiness!).
People blur to maintain the general look of the original image. Having black boxes everywhere is jarring.

In that case, why not erase the numbers and replace them with random digits?
I think you are putting too much weight on the name.

Humans brains are by nature powerful association engines. People tend to associate brand names with their purpose and (perceived) quality pretty quickly. If you've heard of that a once and the product turns out to be good then you are likely to remember it in the future. Why do you think Coca Cola is called Coca Cola and not Black Sweet Beverage? Heineken instead of Dutch Beer? Nike instead of Expensive Nice Shoes? Names do not have to be descriptive.

It confuses people for maybe a few minutes. Then they look for information, find it, and they move on. There's absolutely no point giving products generic names because in the long run it hurts the authors by being unable to differentiate themselves from others who do the same thing.

Don't know what "nokogiri" is? Search the internet and the first result will tell you. Looking for an XML parser but don't know its name? Search the internet and the first result likely gives a good recommendation.
