I have an abacus and an instruction book on how to use it for decimal calculations. The five beads on the bottom each represent one, and a bead on the top represents 5 - yes: ten can be represented in two ways: a 5 bead and all five one beads, or by 0 beads on that digit's rod, and a one bead on the rod immediately to the left. You achieve proficiency by translating addition and subtraction tables into sqeezes and separations of bead patterns.

But why are there TWO beads at the top? Per instructions, one of them is never used!

After many years, I read that certain markets had a tradition of using hexadecimal(!) in which the two five beads and the five one beads gave an exhaustve range of 0 to 15. When I retire, I'm going to spend a few weeks learning the hexadecimal addition, subtraction, multiplication, and division tables and get them into my fingers. Finally, a superpower!

From what I've seen the Qualcomm chips are really great but impossible to buy if you're a normal human, the ST chips are pretty solid and have a configuration tool that works well in Linux and their -WB versions support wireless and bluetooth but use more power than the Qualcomm chips. Then there's microchip (owner of atmel) which has a wifi integrated chip, but it was really hard to get to work.

ESP32 was also super easy to get to work, and I prefer it to the microchip series, see it as a budget version of the ST chips (uses a lot more power but that's fine if it's not on a power limit), and much easier to source than the chips that are meaningfully better.

So yeah, plenty of vendors of equivalent functionality, just different ecosystems for the firmware, of course RISC-V isn't the same as ARM (which the older ESP32 used) so that introduces some quirks into the toolchain, and of course the vendors chips aren't pin-compatible.

You're definitely making a new board if you swap the microcontroller because it's out of stock, that's nearly impossible to avoid -- your best hope is to pick a vendor with a good track record or just buy all your inventory up front, and if you're super lucky the vendor will sell different versions with the same footprint and basic design with different amounts of RAM and such with different availability so that you can swap chips based on supply chain stuff for short term issues.

But a lot of these chips are still made by TSMC I'm sure, so I'm not sure it really addresses the root of how few companies are at the root of the supply chain.

Notice that it is not full bamboo, though. The crucial parts that take a lot of stress are still precision metalwork (e.g., axes, bearings, even the frame corners). I doubt an ancient civilization without very advanced steelmaking could pull such a "bamboo" bike.
Agree so much! having billions of individual intelligences running around with the ability to kill each other is actually hard to manage.

Change management is what makes organisations work, great processes or systems are just a bonus.
This is also a story about how complexity is at odds with availability on many levels. Ceph, the fancy RAID controller, and XFS are stacked building blocks to get more 9's of availability in the model where the enemy is hardware failures, but make it harder to understand the whole system well enough so you know you can operate, troubleshoot & recover it.
It also supports 6GHz, but that doesn't mean a specific radio supports all bands. This is a 2.4GHz-only part.
> Alternatively, you could try to "reform" trains. Instead of long ones that depart every several minutes, why not single, lighter wagons that depart when you need them?

I think that would be a pain to manage and would lower throughput by a wide margin.

As someone living in Paris, which supposedly has great public transportation (according to the local transit authority), what we need is more throughput.

The main issue I see is there not being enough trains, even on the automated lines. They practically come one after the other during rush hour. I don't have the actual numbers, but as an onlooker, it seems as if as soon as one train has left the station, the next comes in. I think this is the best throughput they can get for the given station length.

And yet, there are a few stations (mainly the "small ones") where you'll have to wait for up to ten minutes to be able to board a train, and even then you'll be squished by other passengers. That's because basically no one gets off the train at those stations, so no space frees up.

I think the issue is clearly around getting on and off the train. So now that we have automatic trains with automated gates, they could have different kinds of trains for rush hour. For example, there could be much less or no seats at all and the train doors could open upwards. So instead of the people having to squish through small openings, they could get on and off through practically the whole length of the train.

I always have the opposite idea, Chrome is a total mess for me when it comes to UX. Probably just what you are used to first.
But why have them at all, especially if we’re going to shoot for arbitrary amounts of time?

I don’t buy that IP protections incentivize innovation anymore than they prevent it. The reality is that the gains from intellectual property are not distributed evenly, and corporate executives know this. If IP is making you millions of dollars, that is a very different situation from IP just “making you a living.”

Even if you are doing well as a small IP-based business, you’re still stuck paying a premium on everything you buy (thanks to the existence of IP monopolies), and you still have little recourse against IP violations from large corporations and anonymous pirates.

I just don’t get how this isn’t all an enormous waste of resources for anyone but the already rich, or a completely raw deal for people who mod games, remix music, repair electronics, etc etc.
I think there is a small but important difference when Spotify enters the kind of agreement they did with JRE, effectively becoming his publisher. I see them as more responsible for his content than e.g the lyrics of any song in their catalog.

> Will you not shop at a bookstore that sells Alex Jones books?

It depends. I’m not going to judge a store by having a large selection of books including things I disagree with. But if the store has a huge display of Jones books on a big table in the center? An Alex Jones book signing is taking place in the store? Yeah I’m probably going elsewhere.

The risk here I think is that people like Alex Jones are included in what we call “the political spectrum”. He’s not part of it. Booting him isn’t a political stance. He’s not some voice of right wing politics or even extreme right or “alt right”.
Yes, but 5GHz is not mandatory for WiFi 6.

I think that things that are not js execution time for actual site functionality are much worse for the overall web experience, namely js execution time for ads/trackers and overall latency caused by bad connection quality or bandwidth.

Read the blog, found it somewhat interesting. Prohibiting destructors and only allowing consuming methods is certainly easier when you don't have an exception system.

Bidirectional pointers is definitely something it does better than Rust. Constraint references are an interesting idea. Clasps remind me of some Qt objects automatically detaching other objects listening to them, when destroyed (eg. QSortFilterProxyModel's source model, referenced by QSortFilterProxyModel, referenced by QAbstractItemView), but it feels ad-hoc for every individual type, and I don't know if there's underlying principles that all Qt types follow.

The descriptions of the language and others feel a bit crank-ish at times, I got lost a web of hyperlinks to various pages on the site and didn't read all of them, and apparently the language is not ready yet. I might check it out again when it's more complete.

ESP-NOW might be suitable, as it requires less power than regular wifi.

From the docs:

“ESP-NOW is a kind of connectionless Wi-Fi communication protocol that is defined by Espressif. In ESP-NOW, application data is encapsulated in a vendor-specific action frame and then transmitted from one Wi-Fi device to another without connection.”

This is probably the biggest database of bat-origin coronaviruses in the world, and we're in the middle of a bat-origin coronavirus pandemic. Even ignoring the question of SARS-CoV-2's origins, shouldn't this be of great scientific interest? (If it isn't, then what was the point of the research in the first place?)

Perhaps I could believe that a small group of virologists would have trouble keeping a website running, and that just by chance they gave up right around when a pandemic likely first entered humans, of the same type of virus that they studied in the same town--coincidences do happen. But now that this is a matter of international importance, do you really believe that no one in China has the technology to make this information available in any form? That seems impossible to me; so why don't they want to?

I appreciate the opportunity to discuss, and I do believe that you're sincerely convinced that the chance that virological research could result in such an accident is negligibly small. With respect, I'd suggest that your attitude seems typical of the profession, and that that's exactly when the worst accidents happen. Engineers are constantly taught that their work may bring catastrophe, and that it's their job to consider and manage every conceivable way that it could. I get the feeling that virologists aren't, perhaps because there are fewer past disasters to point to; though with the 1977 flu pandemic as a warning, that's not a great excuse.

"A one in 10,000 chance of dying in a plane crash in your lifetime is a not trivial probability.

I used to work for a consulting company with over 10,000 employees, many of whom traveled constantly for years on end, and, sure enough, when the AA plane to the Dominican Republic crashed in Queens, NY, one of the company's employees was on board. It was bound to happen sooner or later."

Me too, I just never switched when everyone else did. It's always just worked for me.
Great, can you tell me more about your position and why you feel that way?

As follow-on work to Dream, I'd like to take a very hard look at how we do JSON server-side, to really make it much easier. Although this is partially solved by using GraphQL more :) Ideally, in the end, we will have a very fluent server programming experience.

Same goes for SQL prepared statements. I'd like to decrease the amount of boilerplate somewhat, hopefully without resorting to preprocessing.

This is part of the reason I didn't add too many helpers for either JSON or SQL to Dream yet - there seems to be considerable room for improvement here.
I mean “sponsoring” or “enabling” to a level beyond just existing in their catalog does.

Buses are cheaper because they don't pay for the infrastructure.
I found this way of thinking - where you pool risks across the entire population - never particularly useful.

For example, the risk of drowning, here quantified as "1 in 1,128" is actually pretty much 0 for people who don't go swimming, and probably vastly higher for people who frequently swim in lakes.

Similarly, your risk of getting eaten by a shark - as miniscule it may be in the grand scheme of things - is profoundly higher when you're actually in the water somewhere in South Africa or Australia.

So in order to truly understand risks, one really needs to take one's personal setup and situation into account..

One downside of using wifi if that devices like phones really don't like network connections that don't route to the internet. You sometimes have to fight them to stop the phone "helpfully" falling back to 4G or popping up all sorts of warnings about degraded networking to the user.

[edit]: This is assuming you are connecting directly to the device of course. Connecting the ESP32 to your existing wifi is well supported and much more reliable.
Crazy Week for Indian Startup Ecosystem – Six Unicorns in a Week
I think Logitech is the Google of input devices. And not in a good way. They tend to design awesome, clever, stylish devices (used to be of good quality too, not so sure recently) only to kill them silently after a short time. And when I want to recommend one to others, buy a second one or replace mine a couple years later, I find they no longer exist. I've largely stopped buying higher-end Logitech devices because of that, even though I love(d) so many of their products.

Among cool Logitech products which have been killed even though they had no equally cool or better alternative:

1) Logitech diNovo Edge (a beautiful keyboard with an upright stand, ideal if you need desk space)

2) Logitech Presenter with green laser, timer and display

3) Logitech diNovo mini (the best ever tiny media center keyboard IMO which ran circles around the $20 cheap China ones you can get exclusively now; it looked so futuristic, it was even used (unmodified) as a prop in a sci-fi TV show as some kind of futuristic communicator

4) Logitech Cordless Optical Trackman (where the ball is in the middle and not operated by the thumb). This device is so great and coveted that it now goes for high three figures on eBay (originally less than $50).

And a couple more which I can't think of off the top of my head right now.

They came up with a few interesting products in the last years which I would have totally loved to buy but just didn't because I knew they were going to be killed again within a year or two.

What weird world is this where keyboards, mice and laser pointers become expensive "fashion accessories" and you can't rely on equal or better replacements being available at least for a 5-10 year lifespan?

It must be so frustrating to be a product designer at Logitech, designing all these beautiful, close-to-perfect devices only for some bean counter to pull them off the shelves if they can't create hundreds of millions in revenue from them... :-(

I've been a daily user and advocate of Firefox since Opera changed to using Chromium. But recently I've grown tired of their privacy hypocrisy and company decisions that I've uninstalled it and started to try out Edge/Brave/Vivaldi as my daily. It has pained me to do this as FF was my last safe haven away from Chromium.

If you dig into some settings and follow tech news, I have begun to question some of Mozilla's controversial settings, deals with 3rd parties and their political blog posts. I also have a problem with the CEO making $3m per year yet a continued market share decline since she came on.

Just a few of the things off the top of my head that I feel betray my trust of Firefox (all of these pertain to default Windows install):

1) Enabled by default all of your website DNS requests going to Cloudflare with a "promise" this information is not being used or sold. We all know how solid this promise has been for other large tech companies. All under the promotion that DoH protects you from your own ISP.

2) Upon install, FF installs a scheduled service that runs daily. From what I've found out, that service is sending back to Mozilla what your default browser is on YOUR PC (why is that their business). This scheduled service remains on your PC even after uninstalling Firefox and continues to run daily.

3) Enabled by default are Browser Studies and testing a clean install one is already installed and active called "F100 Snippets". Studies allow the Firefox team to install stuff right to your browser whenever they want, to gather telemetry .

4) "Recommended extensions" enabled by default. Got a nag for a recommended extension after few days of browsing. So FF must be scanning your browsing history in order for this to work?

5) this result: https://brave.com/brave-tops-browser-first-run-network-traff... . While it was from 2019 so needs to be updated, but upon first-run I was shocked at the results for FF here.

6) Firefox on Android has a known tracker embedded and enabled by default called Leanplum. From Mozilla's own website they state "Leanplum is a mobile marketing vendor"

I'd love to support and use FF solely again, but I think they need some serious shaking up, starting with a new CEO (who allows this stuff).
The way I see it, it's there to soak up flavours from food that the rice accompanies. I think the texture is quite pleasant as well.

Does that actually happen?

And it's worth noting that the EU is very, very different from country to country, so it's a bad idea to generalise.

None of them have at-will employment though, so it's an appropriate comparison to make.

I think the real difference here is what people value. Personally, I value having some advance notice that the boss hates me and wants me gone. This reduces my stress, and allows me to find another job before I stop earning money.

Perhaps other people value the efficiency that comes from being able to change staffing on a whim. I don't think either of these is wrong, they're just different statements of values.

And note that if we're talking about tech people founding US companies, it's driven predominantly by access to capital rather than anything else.

Do you have any examples of this?
Same here in London on the tube - if you need to wait more than 5 minutes you know that you basically have zero chance getting on the train that does arrive because it will be literally full of people - not just no seats left, but every possible available bit of physical space will have someone contorted into it, and the doors will slide against someone's back/arms/face as they slide close.

There are only 4 doors per carraige on most trains, which means physically getting people in an out when it is entirely full is difficult.

I've often thought that a train with no seats would be great, or ones where the entire side of the carriage just lifts up or rolls-up like a roller shutter would be a great timesaver and make everyone's lives a lot easier

> Rail freight dates from about 1930.

This must be a typo. Freight was transported across the US once the transcontinental link was completed in 1869. Also the standard oil trust was broken up in 1911: part of the antitrust was case was its control of rail transport of oil.

Why do you say that rail freight dates from about 1930? Or are you referring to a specific region?

Rail was a key to supply in WW1 and there were lines made in various countries for freight earlier than the 1930s. In the UK your find references to regular rail freight services from the first half of the 19th century.

Yup, and I see what the author is doing there. That's great, whatever. But if he is illustrating his point by trying to explain a magic trick, and even including a "spoiler warning," I want him to actually explain the magic trick. Otherwise, it's a kind of a comical piece of rhetoric. "Some jobs are like this magic trick I'm about to explain. First, you do something cool that seems like magic. Now you see, magic and work share an element of extreme tedium!"
