I've done a similar journey during this lock down year. I started off with a small design of a custom latency measurement thingie that was a "rats nest" with wires and components soldered to an arduino. Converting it to a PCB, I used easyeda.com. I recommend that over KiCad, which I later tried but it's clunky compared to Easy EDA. KiCad feels like blender before the re-work they did. Or InkScape. Opensource has such incredibly crappy ui:s sometimes... Yay Blender!

First batch was bare PCB from jlcpcb.com and components from digikey. Handsoldered it. And it worked!! OMG, the JOY!! I highly recommend to do some simple own pcb design.

Then I did v2: STM32, ws2812b, tiny smt components. I used jlcpcb assembly service, complemented with some components they didn't have in their (limited!) smt library. Bringup of the first stm32 was a bit of a nightmare. I had missed pulling a boot0-pin low (~2 days wasted). A co-worker is madly in love with rust and made me write the whole code in Rust (2 weeks maybe, not "wasted" per se - but oh man can embedded rust be... a lot of fun... sometimes). Missed pullups on i2c lines. So much learning on version two.

Version three I tried to keep is simple. But also smaller. I had an idea to use 3.5mm audio cables for power and data. I thought SMD audio cable contacts would be rugged. I was wrong - they came off. I had bought a syringe with solder paste and one with flux. Totally recommend getting a flux syringe! So good! But that solder paste... I maybe didn't grok how to use it, but it did not reflow well enough to make the audio cable contacts stay put when used.

Got version four a couple of weeks ago. Doing pcbway.com with them doing the full smt and through hole soldering. This is how to do it! I do not at all understand why all are raving about jlcpcb.com - they have such a limited library. Why not make a proper pcb shop solder it all? It doesn't cost that much more. If time is a factor it is a lot cheaper. V4 feels like a winner - shipping them out to customers now.

I've also done some other boards during the lock down, such as control boards for RC cars in three versions, and three versions of an Ethernet connected microphone. I'm still on EasyEDA, but as mentioned I now let pcbway do soldering of everything.
> I have no idea why motorcycles aren't more used, especially in areas where there's no real winter.

As a motorcycle rider myself, I think you simply don't understand how bad it gets in ATL (both during summer and winter).

I currently live in Seattle, and it rains quite often, but it is just a drizzle most of the time, and I can still ride quite comfortably. Summer is a bit too hot at times, but nothing wild. Winters are fine too, aside from those very rare snow days.

Before moving to Seattle, I used to live in ATL, and I can tell you I would never ride a motorcycle there for multiple reasons.

1. It doesn't rain as often in ATL as it does in Seattle, but when it does, it comes out of nowhere and it pours buckets. Impossible to ride, even driving a car feels extremely risky with those rains.

2. Winters in ATL tend to be colder than in Seattle a lot of times (not averaged out, but on a day-to-day basis; e.g., one day in January you wear a winter coat, a week after you wear shorts and a tshirt, and another week later you are back to your winter coat), and summers are always much much hotter and much more humid. Weather swings much stronger in both directions. Humidity is a total killer. Riding in ATL during summer is pretty much impossible, unless you invest into cooling solutions (like cooling vests and such, which barely work for longer than 20 minutes at a time, as I found out from my own experience). You mention Phoenix, but the crucial difference is that air in Phoenix is very dry, which is much better for riding (or being outside in general). I witnessed 95F+ temps in Seattle (which also has dry air) a few times, and didn't even blink an eye and was able to stay comfortably outside. In ATL, I couldn't stand being outside even for a few mins once the temps climbed above 75F. Overall, I would say ATL has way way less rideable days than Seattle, and that's despite the Seattle rain.

3. Last, but not the least, drivers. While this isn't the main factor in my decision to never ride in ATL, it could be for a lot of people. Drivers are very aggressive, with many coming from very rural or suburban GA, driving giant trucks and having some animosity towards motorcycle riders specifically. I am not joking about the last one, I legitimately heard multiple people claim they wished it was legal to hit motorcycle riders on the road. But again, this point is just a minor one for me, as it is much more subjective than the first two and can be just written off as my personal experience aka anecdata.

With that in mind, I just want to say that this is not my critique of ATL as a city overall, just when it comes to riding a motorcycle there. If ATL manages to get the career opportunities for devs going with all those tech companies opening big offices there, and it all succeeds, I would consider moving back, despite the weather. ATL has quite a lot of things worthy of praise and appreciation that I miss while living in Seattle.
I can't open the article. With the issue of environmental sustainability nearly fully addressed, what's the issue now?

People will soon be spending larger portions of time in their cars, and there will be novel ownership models once fully autonomous driving is achieved. We may even end up living and working there.

Anti-car sentiment will become a luddite view. Transportation (as well as the networking of physical spaces) has always been a major driver (no pun intended) of human progress. Perhaps it's fitting that a "newspaper" is expressing this sentiment.
The long term roadmap for MyCoin™ is to hit twelve bajillion transactions per second by next Tuesday.

It isn't easy to hit those throughputs on a normal system where nodes are reliable and trustworthy, workloads are carefully controlled, and latency is under a millisecond. There's no reason to think Ethereum can pull it off.
Fair point, but part of risk analysis is looking at what can happen when a tool is not used as designed. Obviously you can't cover all eventualities, but one thing you should do is focus on the worst possible outcomes and work them backwards.
Watching the live feed was a blast. When they said they received the exact landing coordinates I was extremely curious to see it plotted vs their targeted landing zone, but unfortunately they haven't shown it yet. However, I could audibly hear an engineer in the background say "Oof, well, we'll take it!"

Anyone seen anything about the precise location yet?

Belarus previously had 99% of its electricity produced by thermal plants. The new NPP will produce 30% of the power in Belarus and seriously reduce greenhouse gas emissions.

You can set your own threshold that's not way beyond. The point is that it's not unfalsifiable. There are pretty reasonable scenarios where you could find a group of consistent market-beaters and falsify it.

If there aren't enough exploitable inefficiencies in an entire career to make that proof, then that's an interesting data point all on its own.
Doesn't, I wanted to show how it can be wired to request.
That is most certainly correct. They also mentioned that these are images from engineering cameras, so they are normally responsible for navigation. The real HD footage will come in over the next hours as the bandwidth just is not large enough.

The Lost Book of Remedies
minimaxir: Great insight and probably merits an edit for precision. My understanding is that Byte-Pair encoding is done at the character and word level (and maybe even the sub-character level), but not at the higher-level representations such as paragraph, section—and beyond. Am I mistaken? Taking a few steps back, is that an effective way to pinpoint context?

The goal should be to properly ascertain context at multiple levels. When I am reviewing a document, I scan the document title and section headings to grasp the structure of the document prior to diving into the relevant clauses and their elements. If there are external references, I will integrate them before reading the clause in order to capture the complete rule. A crucial mistake in contractual interpretation is falsely attributing an element from one rule or section to another, or excluding an element. What applies in A context might not apply in B context, or it may be conditional on another factor C.

The criticism I intended to make was that GPT-3 likely is not (accurately) identifying the right context “bucket” before making the prediction and that perhaps could be improved by tokenizing different levels of context. I may have falsely reasoned that this could be best accomplished through tokenization at different levels. In context of the paper, GPT-3 referenced Tinder and MommyMeet when I inputted Linkedin’s Privacy Policy. Also, if GPT-3 contains Section 230 in its training data, it did not look to the definition list at the bottom of the statute to the define a key term (I excluded the definitions from the input). My hunch is that a better approach would localize based on the document, section and clause type to precisely narrow the context before utilizing character and word level predictions.
So should you be able to take a free copy of a movie that people spent years and millions of dollars making?

I think a little more nuance is warranted here.

> lower GDP growth on average

Europe is the largest surplus region on the planet.

I don't get where this idea came from, Europe does the most impressive technology, but doesn't constantly market themselves as well.

US is the largest deficit ( needs to constantly import capital to just survive ) country on the planet.

If your GDP growth comes from debt, then you are doing it wrong.
Consumer protection doesn't apply to broad statements like "secure". Just because a kwikset advertises "For use on exterior doors where keyed entry and security is needed" doesn't mean you're entitled to a refund if someone picks it, even if kwiksets are usually seen as low-security locks.

NASA's ability of succeeding at landing things successfully on the first try on foreign bodies since 1969 is mind-blowing.

https://en.wikipedia.org/wiki/Mars_Climate_Orbiter

> The spacecraft encountered Mars on a trajectory that brought it too close to the planet, and it was either destroyed in the atmosphere or escaped the planet's vicinity and entered an orbit around the sun. An investigation attributed the failure to a measurement mismatch between two software systems: metric units by NASA and non-metric ("English") units by spacecraft builder Lockheed Martin.

https://en.wikipedia.org/wiki/Mars_Polar_Lander#Landing_atte...

> Communication was expected to be reestablished with the spacecraft at 20:39:00 UTC after having landed. However, no communication was possible with the spacecraft, and the lander was declared lost.

The parent's point, and I don't know if it's well-founded or not (and consequently I'm not endorsing it, only clarifying), is that adding more waste doesn't seem to worsen the problem.

As an aside, if you must snark, it's best to do it when you're following the thread of the conversation.
Close, it's 1/10th of the spectrum not 1/10th of the intensity.

The 'fancy mirrors' required would simply be a prism. You'd separate out the red and blue light and aim it at the plants, and send the green and infrared light to solar cells, to be used for running red and blue LEDs. (Or you could use flourescence if you had something that glowed red or blue when exposed to green or IR light).

Check out this spectral plot for chlorophyll-a and -b:

http://hyperphysics.phy-astr.gsu.edu/hbase/Biology/ligabs.ht...

and compare it to this plot of the solar irradiance at Earth's surface:

http://hyperphysics.phy-astr.gsu.edu/hbase/vision/solirrad.h...

There are peaks in the clorophyl absorption spectrum at 400-500 and 600-700 nm (blue to UV and red), but the sunlight provides energy in an atmosphere-attenuated blackbody curve everywhere from 300-1000nm.

In theory, by providing illumination with just 10% the energy of the sunlight's full spectrum in a narrow band from 420-430nm where photosynthesis is most efficient, you could have plants receive the same amount of energy.

Unfortunately, solar cells have the exact same problem: Just as the proteins in chlorophyll only use certain spectral energies, so too the semiconductors only make efficient use of certain energies. Multi-bandgap solar cells can help:

https://en.wikipedia.org/wiki/Multi-junction_solar_cell#/med...

but in both chemical and electrical solar energy extraction, you're working with a particular photon energy and there's going to be waste.
I'm doing probably the umpteenth repost of this article here because I wonder to what extent it's still good advice. In particular, if I engage directly with users, e.g. by contacting them about a problem they're having with my product, will I creep them out, and possibly lose a sale, by letting them know that I'm watching them? Has sensitivity to privacy invasions gone up enough that we have to be more careful now about doing things that don't scale?
From the announcement it seems this is driver-side only, so a big nope.
Citadel is basically a vacuum cleaner for top-end talent.
Worth noting that these first pictures are sent in the first seconds after touchdown, you can even still see the dust in the air from the landing (even if it was craned down to reduce dust). It also explains the very low resolution in general, they want to get confirmation ASAP, no time for high quality high resolution images.
Wind did fail spectularly. It was producing 15% of its installed capacity last night. It's all the way up to 30% now with more favorable conditions. Every other generation source vastly outperformed wind.

Saying that wind exceeded expectations is like saying that your QB with a broken leg exceeded expectations by making it to the bench. You should still be looking for a QB that can play.

If the argument is that wind is nearly useless in the winter by design, then that is all the more reason to promote alternatives. No one freezing right now is going to be comforted by the knowledge that our wind capacity was planned to be unavailable when it's coldest.

Solar is fine, and is a trivial amount of the installed capacity in any case.

Didn't they reuse the solid rocket boosters for the shuttle? (Granted, they were delivered by Morton Thiokol and didn't function well in cold weather...)
Thank you for bringing up that little gem, A4Tech KV-300H is indeed excellent value for its price. It had very good user reviews in my country; I bought it few years ago for about 20€, as a successor to an Apple Wireless Keyboard. Sturdy, wired, classic full-size ANSI layout, with accessible modifier keys (no FN/multimedia keys). A bit creaky, but nice option if one prefers low profile, chiclet keyboards.

Also, for some people comfort beats all other factors, including durability. Mechanical or not, since I switched to Microsoft Natural Ergonomic 4000 at work, I really don't care what is under the keycaps. Improvement in comfort is so massive for me, that even if keyboard would completely break every 2 years, I would just happily buy another one.
What is the worst that can happen? We don't get our own money back from ourselves?

Our future selves find that the cupboard is bare because our present selves squandered it all. Printing money now is a gamble that the real economy of goods and services will expand at that rate over the long term. It’s not by any means certain that it will.

You just need to hedge the fixed mortgage you are selling and add some interest to make profit.

The lower "HazCams" hazard avoidance cameras (which captured those initial photos) are there to detect hazards (rocks, trenches, etc.). They are stereoscopic, lightweight, and high resolution.

My guess is that using color sensors would have either increased the 3D mapping precision or added weight/power/bandwidth requirements, or otherwise been less robust in that environment.

Those cameras were also pre-deployed for the landing phase and likely transmit more quickly due to the lower data information. The other cameras were shielded for the landing phase.

The navigation and other cameras are in color, and I expect we'll be seeing better images shortly.

Not exactly. I have a Model M made in '86 or so, and I used that for a while but wanted a more modern version so I got the Unicomp. I was sorely disappointed because it was not the same keyboard. The Unicomp was significantly lighter than the IBM model, and I could flex the body of the Unicomp without too much effort whereas you could park a tank on the IBM.

The innards may be mostly the same, but it definitely was not a "Model M, but made more recently and with USB".
Great to see people learning and designing PCBs themselves - it's a fun and rewarding hobby!

There are a whole bunch of improvements I'd suggest with this particular design and article though: (also, doing six respins for a board this simple is a bit painful, and I'd encourage people to submit their layout to someone for a design review before going through this many iterations - I've reviewed things for friends in exchange for a pint of beer!)

- this board has no ground plane, and no return paths near the data traces - this will be an absolute EMI nightmare and also signal integrity will suffer. At very least, dedicate the bottom layer to ground (and flood-fill it) - the return path for digital signals (and anything above a few KHz) is directly below the signal path - see https://incompliancemag.com/wp-content/uploads/2017/04/1705_....

- (the clock design, in particular, is completely against ST's recommendations - there's no ground plane and traces running directly underneath!)

- panelisation: as others have mentioned, even for large-scale production runs, the PCB manufacturers will do a better job of panellising themselves, and can stack your boards in amongst other boards on the same panel if you're not taking up a whole panel.

- unless you've got a good reason to do it, having a serial programming interface with a serial/USB chip isn't the easiest way of doing it - exposing SWDIO/SWDCK/SWO to a suitable connector and using an ST-Link in-circuit programmer is generally an easier and more space-efficient way! They seem to have gone that way in the last couple of revisions.

There are a bunch of other things I'd probably do differently, but this is all to say - if you do decide to take up this hobby, please do get your designs looked at by someone knowledgeable, you'll learn a lot that way!
any chance you could help find a source for that?
There are a lot of people out there with unfounded mistrust. Some of it is justified, some of it is not. These things are not mutually exclusive.
