>despite the aid of a shoe that designers say will make runners 4 percent more efficient.

Seems like this could be a big factor. A shoe itself acting as a spring and helping the runner make bigger strides with the same effort. I won't be surprised if the official race wouldn't allow these "enhanced" shoes.
This article is spot on. I grew up swinging on these as a kid, then helping out with the washing, then playing goon of fortune as I grew up.

I have been following this project since it was published on hackaday.io. Congratulations to Oskar and the rest of the contributors for getting it to at least alpha production.

Question: I could not find information on what kind of control modes are supported- position, velocity, current/force?

Aside: I have previously used another similar product: VESC, which was born as a driver for electric skateboard motors (Odrive was not available yet). I used two of them in current control mode with feedback from magnetic encoders. Since motor current is proportional to torque, it's quite useful control scheme if the motion equations of the system can be expressed in terms of force/torque (which most of them are, if you think about it).

One such example is car's accelerator pedal: it controls the torque exerted by motor, which exerts force against road, which makes mass to accelerate.
The acceleration in turn increases velocity of the car, which in turn changes the car's position.
While this looks obvious after one has thought about it, it actually means that the common linear control methods (e.g. PID) won't work optimally (if at all) if you try to control position by changing acceleration.

I was commenting to the GP about technologies to replace JavaScript. On the long term WASM is the best candidate, though it's indeed not one of the intended goals of the project. JS will be with us eternally, rest assured. But if DOM-enabled WASM would one day gain wide adoption, developers targeting contemporary browsers of the future would at least have a wider selection of runtimes to choose form in addition to JS.
Suggestion: why not use three cameras simultaneously, each from a different angle, then classify the three images? Those cameras must be nearly free in cost.

Also, to get more training data, what about setting up a puffer to blow the part back on the belt and tumble it? If you could configure the loader belt to load parts slowly and stop after one is seen, you could automatically re-image the first part an arbitrary number of times by blowing it backwards before letting it move along and restarting to first belt to get another.

And question: do you normalize out color at any stage? As in, classify a black and white image, with a separate classifier for the color?
Why didn't they just publish the torrents and the metadata? E.g. daily via automated torrents.
So that's where we are. And the US did terrible things. It shameful and it should never do those type of things again.

But the conflict should have been finished rather than being left to fester for decades. The society could have been rebuild and almost certainly would have prospered.

So now we have a problem. I don't think Kim can be left alone, he simply is too dangerous. Talks and negotiations and sanctions haven't worked. I doubt they are likely to in the future. I believe he will simply continue to acquire destructive technology affecting the balance of power in the region and possibly the world and at one point may well use it as he continually threatens to do.

I am pretty anti war. Extremely anti-colonialism. But in the case of NK I think the situation needs solving and soon. I believe they should be disarmed, by force if necessary and I'd support this even though I support almost no other US military adventures. It's a shame we let it get to this point but we did somehow. I say this as an American with American and allies interest in mind. I suppose there are other perspectives.

I'm not advocating removing the TSA entirely, just pointing out that we are paying a heavy price for a likely small benefit.

Locking the cabin door virtually eliminated the threat of turning jetliners into terrorist weapons at a tiny cost. But on top of that we've cost the country maybe a trillion dollars in excessive and invasive security procedures to prevent planes from being blown up. The TSA is only one part of those costs, longer travel times, reduced travel and lost liberties are a big part of it.

The value to terrorists blowing up an airliner is relatively small, there are far easier and cheaper ways to kill a few hundred people to make a political statement.

So my real question is, if we reduced spending on airport security, and reduced the level of security significantly so that we shaved 15 mins on average off every trip, would it be worth accepting a plane being blown up every few years?

Every year the US has nearly 1 billion trips by air. If you value travelers time at $20/hour, saving 15 minutes per trip directly saves nearly $5B a year. If the cost of saving those 15 minutes per trip is 50 lives per year, we are valuing each of those lives at $100m each. That seems incrediably excessive to me. Of course this is just a rough estimate, run your own numbers but it's hard to imagine the costs get down to a barely reasonable $10M per life level.

and remember that doesn't include the cost of the TSA or the cost of flights not taken.
If the government really cared, wouldn't/couldn't they just force banks to forbid transactions with known tax havens?

I think finding the topic is the harder issue. Or picking a topic among those you are interested in.

If you are interested in a specific topic, then usually you can find discussions of "game changing" books in that topic. Or trace the "tree" of current books to earlier books in the topic.

If you want to know what influenced an author, take a look at the sources the book cites. A quick Google search revealed a bunch of sites which offer search for book / pub citation info. Maybe that's a good place to start.

An interesting service might be to take this a step further and add some sort of visualization for a given topic.
While you have correctly identified a trait of those who graze the autistic spectrum, you also appear to have discounted the possibility of being able to ignore social pressure otherwise. I think you are kind of proving the point of the person you are responding to. To me it came off as if the comment made you uncomfortable, and you responded in a way that is, in my opinion, short-sighted. I believe what he meant is that often times with privilege, people don’t feel the need to defend a certain viewpoint - because they aren’t negatively affected by it.

Disclaimer: I grew up poor as dirt in a house of 7 children, so I’m definitely not speaking from experience as far as being privileged goes. I never graduated college, I just read regular old books. I do have a younger brother who struggles with a slight case of autism though, and he has no interest in computers whatsoever. In fact his life is somewhat in shambles. Also, the term “asperger’s” has been deprecated.

> Also, what does "fully converged" signify?

In machine learning/deep learning, the decrease in training loss has major diminishing returns as training continues. Eventually, training the model hits a point where the loss barely improves each epoch/iteration. (fun visualization from one of my projects: http://minimaxir.com/img/char-embeddings/epoch-losses.png)

In some cases, the loss can stop improving entirely, or increase.
That's a great idea. Even better if there were tiny dedicated LEDs near the front facing camera and microphone to make it 100% clear what they mean.

I have compiled a small list of motors that I think are suitable for robotics applications, along with some useful calculations, here: https://docs.google.com/spreadsheets/d/12vzz7XVEK6YNIOqH0jAz...

You can take a copy of the spreadsheet and enter in your own motors that you find. Also do note there is a second tab on the sheet that lets you explore cycle times on trapezoidal trajectories.
They probably mean all the `using` macros, which can obscure where functions are coming from, and make it hard to get a grip on which functions are available in a given scope.

It is not easy per-se, and yes it is used in many dissertations, but most of the limitations up to now have been more related to the performance required to implement a demodulator that runs at high enough frequencies in a low cost microcontroller or FPGA. This is becoming less of a problem with more powerful chips. I don't know if I'd call it a mainstream technique, but it is widely used in high performance IPM motor drives for servo applications.

I think this technique isn't commonly used in lower performance applications because it is an additional cost both in performance (need a more powerful processor) and complexity.

The big problem with high freq injection is that it requires some kind of saliency on the rotor, which means this only works for interior permanent magnet machines and not induction or surface PM machines unless they are specially constructed. I guess I don't know enough about hobby brushless DC machines to know if they are IPM or SPM, but my guess was IPM because they can be cheaper to build for high speed designs and I know hobby BLDCs can spin at 10s of thousands of rpm. Perhaps someone with more hobbyist know-how can chime in.

For this application (robotics) I think the other typical problems with high freq injection are negligible. For example you need a well-defined switching frequency that stays out of the way of your high frequency carrier. Many inverters pull back on switching frequency at high loads in order to lower switching losses, but if you lower the switching frequency too much you won't have enough voltage bandwidth to synthesize the high frequency carrier required for the self-sensing algorithm. I don't think this would be a big deal for robotics applications.

The testing company used appears to be ProctorU, I've used them 4 times for my own online degree. The controls go well beyond simple camera use, they do a lot of checking for programs in the background (programatically, not manually). It can be beaten by a motivated individual, but at the point significant cheating is an issue for a program, there are larger issues to address, like "why do our students feel compelled to cheat?" and "why are tests so valuable that cheating is effective?"

This may be an unusual opinion, but I read a lot, and I've found non-fiction books to just not be efficient means of educating myself anymore. Most topics can be illustrated and described in far fewer words than a book takes. I get about a third of the way through a lot of books and say "ok I get it", as the author basically just continues to say the same thing in different ways. I'm sure this is incentivized by current publishing structure.

Not only that, but figures and plots provide far more information density than words, and books don't frequently include them in large quantity. I've found scientific literature and a number of very high quality bloggers to be a much more efficient source of reading material.

That's not to say this is always true - biographies in particular seem to have the most consistently large content / page count.

I run a product team in a relatively mature SaaS business in the infrastructure space. As you probably know, infra is pretty crowded so there's no shortage of competitors. While we had a unique take at slicing out a niche vertical, I wouldn't say what we were doing was entirely novel when we were getting started. So, it's definitely possible to get into an area where there is already product validation.

As for competing on price. You'll quickly discover that if price is the only criteria which you win a deal that these tend to be your worst customers. They use the most of your resources, are least considerate when you screw up (and you will screw up) and don't expand sales necessarily well. When they realize that they can do something cheaper, they will be the first people out the door. That doesn't mean that customers aren't and shouldn't be price conscious. But, you really want to be winning sales based on perceived value, quality and strategic alignment. Your customers should place their loyalty in you by which you build new features in which they pay you more for. By doing so you inherently reduce churn, increase add-on sales, and turn your customers into your greatest marketing asset.

I don't have a question, but I did want to thank you so much for this service. For our usage, which involves lots of disparate services sitting in all sorts of places, it makes it quick and painless to shuffle around our graph of connections between them for development, debugging, and production testing.

It's a service that, for us, is worth its weight in gold for all the configuration and maintenance we don't have to do. It's definitely one of the first tools in our toolbox we reach for. Thank you very much for ngrok!
I'd like to add though that I disagree with the parent comment about privilege putting people ahead in the moral sense. I believe that some of the most compassionate people have grown that way through hardship.

Interesting! For myself, I tend to already know what topics I care about, e.g Entrepreneurship, History of Computing, Stoicism, etc. These topics usually become quite apparent when I look at my goals in life. Can you explain more about how you decide on topics?

As for the "game changing" books, I definitely agree! It seems that most areas seem to have those "seminal" books that most of the other books in the genre reference non-stop. One example that jumps out at me is Flow by Mihaly Csikszentmihalyi, which seems to be referenced by every book I can get my hands on.

The visualization of a tree is definitely interesting: I suppose the goal of it would to be able to find the roots.
i think 1-5% change in speed is a lot. its interesting tech but it needs to be more acurate. you can currently use floor sensors and high speed cameras. my experience is from sports though and not elderly care. it would be very nice to use something like this to analyse a football game or athletics.
One thing to keep in mind is that for many robotics applications, the duty cycle for high torque (i.e. acceleration) is often quite low. So they may still run fairly cool.
You must be kidding me. We hit a bug with the mysql2 gem where the client randomly crashes in libmariadbclient (but not libmysqlclient) only on debian (using Arch Linux and OS X for dev, but exact same versions of everything) and only for database names of length 25. And 28, but we cannot reproduce it on the repro docker image we made. And only if there are enough aliases in the query (could be as low as 5 but could need as much as 20+). And only if 'active_record' is require'd, but even when it's not used at all. And never ever under GDB or Valgrind, making it the perfect heisenbug.

That's a lot of stars to align there, but when they do, hell breaks lose just often enough to be sure it's not completely random, and obviously this hit one of our most finicky customers, and only in production because of course "#{customer}_production".size == 28 (and not 25, because nah that'd have been too easy to be able to reproduce the bug right away).

I've read more in the past 12 months than in the past few years, purely because I discovered a company in the UK called the Folio Society[1]. They sell beautifully bound and illustrated editions of fantastic books, although at rather high prices (£30-40 on average).

Previously the majority of the books I read came in the form of cheap ebooks from the Kindle store. As a result, I often abandoned them (or even just forgot about them), only reading a few chapters. Now though, when I spend £30 on a single book, damn right am I going to finish it.

Plus, as a result of the curation, there isn't a single book on their site that isn't at least worth a glance. The same can't be said for many physical bookstores, let alone Amazon, etc.

And, the best part is, I don't really need these expensive books anymore. I've gotten into such a habit of reading because of them that I'm buying regular books again and I'm reading for at least an hour or two a night.

I think that another way of looking at this story is some 'god' miraculously tidying up the litter that humans have carelessly left at the bottom of the ocean for one reason or another. In this magic universe the mystery tidy-up persons should be thanked for doing such a thorough job, leaving not so much as a bolt behind.

It is all so much easier if the human remains part is conveniently ignored.

I'd say not holding to the standards of robots.txt and 403-Forbidden is quite malicious, just not evil or bad. If you build a crawler, you should play nice. But bot A-D were easily discouraged.

Eddie however is another problem. It overloads the network, doesn't crawl and doesn't parse the responses. This is not crawler behaviour...

The rest of the post is solid inductive reasoning (from my perspective): the bot is identifiable by his behaviour. It has a faster response time that a source-relay-source roundtrip. Thus the bot must originate there.

This is supported that the anonymous relays were set up just before the attack, all at the same time. And after the attack stopped the majority of all traffic through the relays stopped.

There are also ways to keep your registration private without resorting to fraud. Though probably a number of people think of this as the 'easy' solution.
Does Neuralink Solve the Control Problem?
Oh wow. That's something new.

We currently have multiple dedicated servers out of OVH BHS Canada (bare metal servers) and I have never ran into that problem. Most of the time I believe OVH gives you all the tools necessary. If I recall correctly, I believe their power-cycle feature is sending a SNMP command to the UPS, so their online control panel should technically work, but mileage may vary.

We've started moving on to Colocated hardware though. Unless you specifically need OVH's VAC system or their network (or free 256 IPs with setup fees), I've found OVH's availability of hardware and configurations to be fairly lacking. Glad it works out for you guys though!
