The pitch from Small Robot Company's home page (https://www.smallrobotcompany.com/):

> We’re an agri-tech start up commercialising a deceptively simple idea: small robots not big tractors.

> Because unfortunately big tractors are neither efficient nor environmentally friendly. Currently, 95% of energy is used ploughing. And ploughing is only necessary because of heavy machinery crushing soil.

> We are building robots that will seed and care for each individual plant in your crop. They will only feed and spray the plants that need it, giving them the perfect levels nutrients and support, with no waste.

> This level of detail allows you to be kinder to soil, kinder to the environment, more efficient, more precise and more productive. It’s the best of all worlds. An increased yield, as well as minimal chemical usage. So you can increase revenues by up to 40%, reduce costs by up to 60%.

> Our robots are being designed and built by farmers, for farmers. Because we have spent the last year talking to you, we know you don’t want to buy robots. You are worried about the cost, and what happens if they break down. Instead you can lease our robots through a Farming as a Service (FaaS) model.

Obviously it may not be as good as it sounds. But it sounds amazing.

Also these quotes from the article about scale were interesting:

> The agility of agricultural robots means small farms with compact fields will no longer be at a disadvantage; independent shops and restaurants will be able to grow their produce on smallholdings efficiently tended by Rachel-like machines.

> ...

> “Most people think this is going to be expensive, is going to do everyone out of a job and is going to be good for the big farms, not the small farms,” he says. “It’s actually the exact opposite. The big farms are all about economies of scale: big fields, big tractors. We are developing small machines. I believe the extra production we need to feed the planet is going to come from small farms that can’t use those economies of scale.”

I love the idea of a farmer on 2 acres competing with Big Ag on price.
A bit OT, but perception of discrimination is itself subject to bias, for example discrimination of women and minorities is taken seriously while discrimination of whites and men is laughed off. Bias in perception of discrimination would prevent you from even recognizing existing biases, not to mention weighting them correctly, and possibly lead you to aggravate existing discrimination.
I found this really useful. I've had multiple, unsuccessful attempts at grokking category theory, and never really felt I got it. The closest was John Baez's online course [0].

I don't have a particular aptitude for maths (as an engineer by training, maths makes sense to me as a tool for solving problems - not as a source of study in and of itself).

Most all the introductions to CT I've read get into the maths very early. That's entirely understandable. I personally find I need a more intuitive description of the concepts first, using non-mathematical exemplars. OP is, thus far, the introduction that best articulates things for me in those intuitive terms.

That's in no way a criticism of more formal/abstract treatments: I've great admiration for those who naturally create and assimilate things that way. I wish I was one.

I'm not really sure wasm is meant to compete with JS like that though?

To me the main benefits of wasm are that you can
* make web pages with languages besides JS
* do lower level things not possible with JS (low latency real time games?)

If you already know JS well and want to make a normal website I don't think you need WASM necessarily although it will enable those who don't know JS or want to use JS to make them too.
A few years ago I built a toy app for the Marvel API as a code challenge for a consulting job: https://github.com/ceautery/sixDegreesOfSpidey

It's cute, but needs updated for a security vulnerability in jQuery, and I need to dig in and see why the mocha test for Absorbing Man got borked... although y'all are welcome to submit PRs if you're still looking for Hacktoberfest credits.

The README contains some of the oddities I found in the API, like some search types are more reliable than others, everyone eventually teams up with Iron Man or Wolvie, and the data is pretty incomplete (which makes sense if you have 79 years worth of data to compile from printed media).

* EDIT * - I've done the cardinal sin of leaving my API keys in the project. Marvel doesn't currently give you a way to generate new keys (that I could find), so enjoy while you can, but you should probably sign up your own account once my keys start hitting their API limit.
It won't save you - gait detection is also being used in places like China and that's a lot harder to protect yourself from.

Systems also tend to use regular and infrared images for detection too (at least in the case of ALPR).

We need people to care about these things and how the data is used, we need laws for rules around collection, access, and rights. We need to work together towards maintaining the ideas that support western democracy rather than moving towards nationalism.

I worry that instability from climate change and the refugee crisis that comes from that instability will make things worse, along with the current centralization of wealth/inequality issues and rise of more populist right wing movements.

Individual technical solutions will likely not do much to protect you if we lose the cultural framework around democracy.

Yea, I know it might require the RISC OS kernel to be relicensed.
The T480 is the last of its kind after they butchered the X280. I still have my X230 and use it once and a while but my XPS13 running High Sierra gets more screen time for me.
> Like all coaxial connectors, it was designed to present as little change in the characteristic impedance of the feedline as possible by keeping the spacing between the center conductor connection and the outer shell as close to the feedline dimensions as possible.

The above supposedly explains why coax is better for high frequency, but the sentence isn't parsing for me. Can anyone explain it a bit more?
How efficient is laser weeding in time and energy?

Like, can the robot move down the row as fast as a human weeding by hand? Can it carry a car battery and weed for an eight hour shift?
>So China has the technology to destroy satellites [

Any country that can launch a satellite has a technology to destroy one. It's called a missile. You don't even need to go to orbit - just intersect the orbit of the target and dump a bucket of nails in its path.
Last time I went through some sort of acquisition process, the purchaser had some third party look at the source code looking for stuff as you described to be corrected and this was at least five years ago.
The "global" refers to the fact that it works globally, not that it exists for the good of humanity.

Navstar (owned by USDoD, what is commonly called "GPS"), GLONASS and soon Galileo all have global coverage.
In thinking about this last paragraph, I think it may imply I am suggesting that /only/ government can solve these issues. it would more accurately reflect my position to say that a diverse set of players can participate here, Gov't being one important one.

> I liked to think that maybe they just assumed the influencer was going to mention it was paid or everyone understood that was the case but me .... but it never was actually spoken about.

All major social media (Instagram, Youtube, ...) require you to disclose any promotions. It's absolutely normal in "old" media. I think that it's assumed if the audience was composed of actual business people.
> How has that strategy worked out for Cuba / Iran / North Korea?

It hasn't been attempted. Kim Jong-un, for example, has been raised in Switzerland, dito for MANY children of autocracies, dictatorships and other detestable regimes from all over the world. Their blood money (or, in earlier times their blood diamonds) was, is and always will be welcome for Western banks.
Any country/company who has launch vehicles can destroy satellites. SpaceX could just as easily destroy satellites.
Due to COCOM limits, GPS was never an option for China to use on their missiles.

Edit: I'm wrong.
Good luck!

One thing you might want to highlight is all the developer time that's wasted searching for things (or how to do things) in JIRA. It causes frustration and is a true waste of time.

But again, I don't think there's one issue tracker to rule them all. Gitlab's appeal was less about it being way better, and more about it being fully integrated.
Rust can be difficult to learn and frustrating, but it's also very exciting
It's amazing to look back and see how the public support built up for this over last 40 something years. I am not sure how many more years before this country follows Canada or Uruguay.

I’d assume you would get a performance (and therefore battery) benefit by not maintaining a js layer, though a js layer is a perfectly acceptable temporary solution.
> I am not sure how many more years before this country follows Canada or Uruguay.

At least two more years.
One awesome thing about WebAssembly is that it makes a lot of sense as an extension language. Instead of building around the JVM or .NET to get access to languages on those platforms and instead of standardizing on one embedded language (Lua, Python or JavaScript), I can use anything that supports WebAssembly and double dip with that same ecosystem working in the browser. And that list of supported languages will only continue to grow since we finally have an alternative to compiling to JavaScript.

Now, I don't think it'll "take over" the way C has, but I also wouldn't be surprised to see it edging out other VMs in many contexts, like the Lua or Python VMs, which may end up porting to WebAssembly instead of trying to justify another dependency for your app.

I hope we'll finally get to the point where I can choose what language to use for a specific task based on the merits of the language instead of making the larger argument that it's worth getting it to work in our existing app.
I think they can be both - the liberal vs conservative part is merely the means by which you do so - do you vote small parts of other people's property to the task or do you donate your own property voluntarily to the task.

And lest this seem like a conservative jab - it is not intended in any such manner - I willingly admit that in those times the system worked completely different than it does now in ways that would create a great deal of consternation in both modern liberals AND conservatives.
This. . . doesn't sound convincing to me.

Soil displacement is a function of machine weight AND surface area of tires/treads. Additionally, I'd expect the sharp edges of steel treads to disturb soil much worse than a similarly-weighted tractor with rubber tires.

Without doing extensive calculations, my anecdotal evidence is that I've seen bulldozer track "scars" from a single path that are decades old, while the damage from thousands of bicycles collectively veering from a paved path onto grass appears to heal itself in a year or two.

Well, I wonder if they can link you to your taste in pornography? Facial recognition detects you keep showing up in the adult health aisle in Walmart every few weeks for condoms and lubrication. Also facial recognition noticed you spend 15% more time looking in the direction of other males verses females we predict there is a 74% chance that you are homosexual. I agree facial recognition is an invasion of privacy and seems to have all sorts of bad uses. I hope we as a society at least limit corporations from using it against us. I highly doubt we will stop the government from using it but we don't need Walmart tracking us.
It might appeal to those people who are nostalgic about the sort of elegance and simplicity of the design that went into MS-DOS/Windows 3.1. RISC OS is not quite like that, but it is a fantastic system in its own right, especially since it runs natively and fast on the Raspberry Pi. I hope that this move will create a huge surge in community support of this beautiful OS.
COCOM is a non issue when building your own devices from scratch.

GPS satellites are transmit only so they can’t impose such limits directly it’s device manufacturers that implement COCOM.
Are we back in VR winter? It feels like it hasn't caught on aside from a segment of gamers.
If the religious requirements of the CoC aren't going to be enforced, there's no reason for them. They exist because Richard Hipp is religious.
I saw an interesting hoodie with the brim of the hood was a row of flashing IR LEDs. I asked if they had forgotten to turn on their LEDs and they said "take a picture." I did and got just a bright glowy spot where their face should be. It was pretty impressive, but it would not be hard to put an optical filter on specific wavelengths from LEDs if that became more common.
Yep! IIRC, Carmack learned a lot from Abrash, and then eventually hired him at ID Software. They've been working together for ages.

I think it's pretty transparently clear that even if you hate the drug itself, there have been no obvious disasters in the legalized states. Tax revenue plus no hugely obvious negative effects is a hard argument to deny.

On a broader level, this is exactly what federalism is about - states being able to try things to experiment, without committing the entire country irrevocably.
"the mission to reinvigorate the RISC OS market"

They're nearly 20 years too late for that. The only compelling reason to use RISC OS over anything else these days is nostalgia. Still, it might be an interesting project to hack on.
Relink it again man, I for example just missed it and never seen your project.

I looked it up, and it seems pretty cool and well made.
Kudos on keeping releasing new products.

Maybe people want a slightly different version of the product ?

I for example just never use such things in my professional/personal life.
Maybe your target crowd isn't on HN ?
Maybe submit towards a more subject related news site ?
My workplace is the exact opposite. They scoff at types let alone categories. One guy literally told me, and I kid you not, that he doesn't need type checking, all he needs is to be "careful."

We don't learn things together, instead what happens is if I present something new, another person stays silent looks it up at home on google and comes to work the next day pretending he's an expert on the topic. It's toxic.

He's been really clear for multiple years now that he signed up to put a billion people in VR. I don't think high-end PC-powered, room-scale rigs have any real part in that mission. Are you suggesting he would leave?
I’d describe the acronym as ‘catchy’ more than I’d describe it as ‘useful’.
Fair enough. But I don't think avoiding politics is possible when making a clear distinction between his and other approaches is important to the author.

It's a tricky communications problem to say "I think my approach is better" about a hot topic, explain why, and convince people it really is different, while not implying other ways are worse. I'm inclined to be forgiving, as long as there's an attempt at politeness.
I can't wait to see people get reported for merely being slightly afraid of hell rather than in actual dread of hell.

Of course, since there's no enforcement mechanism this seems to be just an attempt to get credit with customers without actually caring about the question they were really asking.
That's exactly what I was thinking when I tried a more theoretical approach to my web emulator. I wrote a little about my approach in the Wiki [1]. Definitely one of my worst hacks :-) .

I like those insights. The danger with labeling words as violence though is that it leads many to the conclusion that words should be policed in the way physical violence is. A critical difference between words and physical violence is that words can cause harm to a listener based on the listener's interpretation and reaction to those words. If a fist hits my jaw I can't control whether it breaks it. But I have control over how I interpret people's words, and the effect they have on me. A person's words can hurt others even when that is not the speaker's intent, and indeed, sometimes there is no way to express a certain idea that won't hurt certain people. But that should never be pretense to treat words like physical violence in the way we police the latter.

(I'm not meaning to suggest that you were advocating for that. Just that it's a risk of not clearly distinguishing between words and physical violence.)
> One thing that I think is finally entering the mainstream is that 3D printing is actually a MUCH more labor-intensive process than typical mass production techniques.

I suppose you could 3D-print a mold, and from there do cheap production.
This is an interesting not fully resolved debate in geology/paleontology. This is a great article that discusses some of the need for the debate, and the comments on the article in later issues name some of the other major players.

I have wondered about this as well. Sometimes when entering Walmart I intentionally look way down as to try avoid any part of my face on their main camera. I know they have other cameras in the store but as a small for of protest I like to avoid that first cam.
As someone who dabbles with gardening and know some farmers. It is not as trivial as you think.

It helps me to remember in a public forum, whether my point is acknowledged by the OP or not, is only a small fraction of the number of people who may read and accept it. If the OP unreasonably denies or refutes it, in fact they may be silently judged accordingly.

No need to make your good point a hostage in your own mind to whether the OP will publicly accept it.
Which code of conduct was that rule in? :)
”Apple is open sourcing LisaOS”

They will allow the computer history museum to host the source code, but chances are it won’t be under an open source license. That’s what they did before. QuickDraw and MacPaint have a ”available only for non-commercial use” clause,
for example (http://www.computerhistory.org/atchm/macpaint-and-quickdraw-...)

And AmigaOS? Does anybody know who owns the rights to that? ;-)

I just hope we don't end up like California and keep hundreds in fines for smoking in public, open containers in cars, having more than 30 grams, etc. People should be allowed to possess any amount they want, grow as many plants as they want, etc. What's the point of legalization if a police officer can still stop you and search to make sure you have under 30 grams? What's the point of legalization if smoking weed still prevents you from buying a gun or holding down a federal job?

I like Larry Sharpe's viewpoint here - Marijuana should be regulated like onions.
Laws are only as reliable as the integrity of those who write and enforce them.
The 90's were great for independent software vendors and we'd want to bring that aspect of it back so it works out perfectly ;)

I've been thinking about a suite of robots on the residential level that could not only mow the grass and edge it, but also shovel snow, and perhaps eventually prune plants and pick the harvest. Would such a suite (or a base plus a suite of attachments) be practically affordable soon (say, cost less than $5k retail)?

Edit: oops, I guess this should be directed at the small robot company, not the space bots with laser company.
You could just as well typo the ".SECOND" in the above.

The flu shots are not anywhere near 100% effective, which likely has to do with what you note: they are based on a laboratory concoction that tires to predict what the new strain might look like.

Plus, aren't you polluting your immune system with the long-term presence of antibodies that soon become irrelevant (if they ever were relevant to begin with?) It's like stockpiling garbage information in a database. Over time, could this constant introduction of rubbish not tax the capacity of your immune system, so that you lose immunity to something important like tetanus?

There is some evidence that chronic flu shot users, those who get them year after year, actually become weaker against the flu.
