> IIRC the only option at the time for running JS on the server was Rhino

Not really true[0]. You could run server side JavaScript with JScript[1] on IIS as far back as the days of IIS 3.0, circa 1997. JScript is ostensibly JavaScript and tracked the original Netscape releases and then the ECMA standards.

> Smart bulbs (by far the worst)

Maybe some. On the other hand, the Hue sitting here is cold to the touch when not emitting light and is drawing about 0.4W right now--I checked.
Kinda depends on the device. My desktop is at 5W for sleep state which equals around 10 quid per year if my napkin math isn't failing me (5 * 730 * 12 *0.23 /1000). So 30 for a household doesn't seem impossible

Then again that is acceptable to me. Recently realised that leaving it on overnight at 150W idle isn't the best of moves though so now using sleep. Still not quite clear to my why it is idling that high for relatively modern gear.

I say this, because it's very hard to write the policy yourself at the beginning. So let the system run for a week and then use the tools to build the policy for you.

I wish it's easier to sit down and write it, but it's not atm.
Twitter's censorship created the problem of echo chambers. Twitter was never full on hostile toward conservatives, it was more to do with specific issues/narratives.

Conservatives looked at mastodon. Mastodon was worse than twitter, conservatives never made it to mastodon. Mastodon was hostile toward conservatives and this was an unfortunate large mistake.

Conservatives built alternatives like parler or gab. But they failed because they were echo chambers.

>We’ve been steadily working towards the ultimate goal of providing a viable alternative to Twitter since 2016, and have proven the scalability and resilience of the platform through organic growth over the years.

Ironically many of these alternatives like gab stole Mastodon code to operate. Which is very interesting because why couldn't conservatives simply join the mastodon network? As an up and comer you would not only be best suited to invite anyone to your platform.

>listing only such servers that commit to standing up against racism, sexism, homophobia and transphobia.

Mastodon will never be in the spotlight because they have fallen into the same echo chamber problems. Gab supports free speech? That must make them racist transphobes!
They probably did...
Looking at the equation for the radiation pattern of the phased array, the angle dependence goes like sin(pi * (N * d/lambda) * sin theta). If N * d (i.e. the size of the array) is much smaller than lambda, there's no interference pattern.

To be more precise, for the radiation pattern to have a null, N * d must be larger than the wavelength.
One of my old coworkers actually went around with a plug-in power meter and measured what all of his appliances were using.

Ended up knocking something like $800/year off of his energy bill.

That's not to say that certain modern devices aren't highly efficient in standby, but to call this a fraud just doesn't seem right at face value.
I think what the authors are getting at is that many failure conditions are more likely to manifest under load. This includes various kinds of resource exhaustion, including those induced by leaks. It also includes things like timeouts due to long queues, and even race conditions. The higher the load, or the longer it's sustained, the more likely it becomes that such bugs will manifest. In every such system I've seen, from very early days of the internet or old-school HA to modern multi-thousand-machine clusters, there have been bugs that only showed up under heavy and/or sustained load. Both Erlang's supervisor trees and Recovery Oriented Computing (Berkeley/Stanford) are based on the observation that such failures will always be with us, and have influenced many subsequent systems - arguably including CockroachDB.

Interesting! Thanks for the info, I'll give them a go if I get a chance. Also good to know I wasn't just imagining it - my new keyboard will probably end up at home since it seems quieter, while the old one will move to work where it won't interrupt nap time so much.

1. How many people connect to shells on those microcontrollers?

2. How many people actually develop for those microcontrollers?

The numbers of devices doesn't matter. Exaggerating a bit, if you have 100 folks developing for 50 billion devices and 10 million developing for 10 billion devices, we will always optimize for the development experience of the 10 million developers, not the 100.

I'm quite convinced (based on job board statistics) that embedded developers are a minority.

And that's not even counting sysadmins, devops, testers, etc, in which case the community outside of embedded completely dwarfs the embedded community.
The article mentions Gates and how he was essentially retired by Musk with his "pregnant man" tweet . He basically dunked on him like young NBA players dunk on old ones putting their crotch in their face.

Gates, Buffett, Kochs, Waltons are old school billionaires, they behave and talk like old money European royality.

Gates real name is not even Bill but William H. Gates III. Tell me a name which sounds more like AngloSaxon aristocracy and old money than that. You can't.

Musk has shown his superiority both in the Forbes list, managerial capabilities, multitasking, the stock market as well as the ability to make people dream.

As a bonus to all of that he can communicate with the masses who want to follow people who speak their minds on social media and talk to the world and to their 80M followers like they would with their close friends in a room. And yes when you are with your close friends you'll attack, call names and even "fat shame" your enemies, because you know that your friends will always have your back, and Musk followers have his.

That's the reason why Musk is on his way to become the first trillionaire as all those other guys fall into irrelevancy.

People are enjoying this process and support him wholeheartadly. It's one of those rare alignments where Musk succeeding will benefit humanity both technologically as well as socially, politically and as a matter of how interpersonal relationships are handled (both online and offline).

Elon Musk is the man who sees infinite.

Are you sure this effect isn't a combination of the in-person education culture, developed over centuries, having difficulties adjusting to a new paradigm; and the measures themselves (e.g the skill of "coming into class") not being appropriate for the new paradigm?

This is remarkable work. It was great fun to play around with. I have just one request: could someone put together some of the same bits as a bare-metal app for a Raspberry Pi? It would be wonderful to be able to use a Pi as a retro 680x0 machine, not as an emulator with some vast underlying OS that needs to be patched, but just as a something monolithic and lightweight...
I'll ignore cheap as its subjective but where do you live that electricity isn't ubiquitous? are you atill waiting for that new fangled indoor plumbing yoo?
Strange, I've had a very different experience to the author of this, I've actually got a similar spreadsheet I may clean-up and post to show another view point, however in summary.

A couple of months ago I went on a little mission around the house testing the power consumption of devices on standby, as I noticed through my energy monitor that idle power consumption was about 0.4-0.5kW while everyone was sleeping at night, which seemed high to my research of national averages.

To my surprise a number of fairly modern devices I found to have utterly terrible standby power consumption, the new buttonless electric hob in my kitchen, the two monitors for my PC on standby, the TV & Blu-ray player and an Aircon unit just to name a few.

Since then I used a few Sonoff relays around the house to add these to Alexa, the results were actually quite amazing really, about £10 per week of electricity saved, so £30-£40 per month...

So in short, if your similar to me you can actually save £300 a year, I think the key take away here is clamp/monitor your own devices and take a judgement from there, no one house/setup is the same.

Edit, here's a very quick screenshot of the spreadsheet and data I've got to hand at the moment, in time I'll get something better cleaned up and together.

My 'base' load in the house is about 100W.. Containing 3 servers (one 10W-idle Skylake i5 NUC, the other 5W-idle Atom-based, one Raspberry Pi 4), one router, one fibre modem, one 4G backup modem, security system, 5 network switches around the house, 2 Access Points.. Oh and one light (NUC) desktop I run 24/7 but in low-power at night (with most processes suspended). It accumulates to about 100W. All in all that adds up to a lot more than 30 bucks/year, it's about 1 euro per day at current prices. But I need all this stuff.

Everything that drains considerable power is already on a switchbox. It's just the way it is, a smart house saves a lot of power but it costs some too.

Still, we've come a long way. 100W used to be one lightbulb. Now I can run my whole house on that.
What a fantastic little project. Thanks for posting this.
Uh, are you paying for enterprise support? Are you referring to your AWS team's solution architect as a sales engineer?

The support team I deal with has always pulled in the actual devs from AWS if we have a particular question about a service. In terms of understanding our product we send them diagrams and they are well informed.
You’re missing out
Both types of structures have collapsed.
Because they aren't considered political. Platforms are mostly only looking for political deviations, something that a politician or lobbying group could complain about.

If you tweeted that turning off your Apple devices would save 30£ a year, for example, and other people started picking up on it, Apple would complain and it would become political. Twitter exclusively hunts political deviation; they're not even nipple-hunters like the other platforms.

edit: even its search for threats/abuse seems to be modeled on the "Zero Tolerance" policies of suburban schools in the '90s-'00s. Posting finger-guns might get you deleted like it would have gotten a second-grader suspended.

And what is the cost of unplugging devices after every use?

Not just replacing sockets or cables, but is not true that (electronic) devices have a longer live if they are always plugged in?

Are electronic components happy now with the constant power on/off cycles?
In 2050 my daughter would pretty much be the same age as I am right now.

I think I would just spend the afternoon with her, would be interesting to talk with your own kids as complete "equals".

The Keurig is the worst offender... Enormous energy is expended to keep your water hot 24/7.
The author acts as if it's all bullshit, but actual measurements in my house disagree. I have a new (2021) 4k "sky box" from my ISP, a relatively new Android TV (2020), a PS4, a Logitech Harmony hub and a lan switch plugged into one socket. The measurement device shows a total of 35W continuous power usage when they're all in standby.

Programmed a rule in my home automation to turn off that whole socket if it's after 11pm and the lights are off, then back on in the morning. It's around 100 kwh per year, which is more than 30 euros at current energy prices over here.
Because every single JavaScript UI I use is a bloated, slow mess - even “optimized” apps like vscode feel like sludge to me compared to Sublime Text or Nova.

Last thing I want is a sluggish file manager that uses a crap tone of memory with a bunch of “ui renderer processes”.

Try Pathfinder, worth every penny in my opinion.

High-availability database systems go back to 1974 or so, with Tandem Computers.

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

"Tandem's NonStop systems use a number of independent identical processors and redundant storage devices and controllers to provide automatic high-speed "failover" in the case of a hardware or software failure. To contain the scope of failures and of corrupted data, these multi-computer systems have no shared central components, not even main memory. Conventional multi-computer systems all use shared memories and work directly on shared data objects. Instead, NonStop processors cooperate by exchanging messages across a reliable fabric, and software takes periodic snapshots for possible rollback of program memory state."

The general ideas of failover for high-availbility go back much further.

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

"The term "failover", although probably in use by engineers much earlier, can be found in a 1962 declassified NASA report. The term "switchover" can be found in the 1950s when describing '"Hot" and "Cold" Standby Systems', with the current meaning of immediate switchover to a running system (hot) and delayed switchover to a system that needs starting (cold). A conference proceedings from 1957 describes computer systems with both Emergency Switchover (i.e. failover) and Scheduled Failover (for maintenance)."

Also worth a mention that the well known Paxos distributed consensus algorithm was described in a 1989 paper by Leslie Lamport, and the almost identical (but less well known) predecessor Viewstamped Replication in a 1988 thesis by Brian Oki.

100 times this. I’ve worked at a company with a commit history going back to 1979 (literal paper logs at that point, plus in-file headers), and another company where we lost ~2 years worth of historical context/info to WIP commits because “our internal GitHub instance has that info” turned out to not be true when we migrated to a new instance. Nowadays, the relevant info from our PRs gets copied to git, and I hope in 40 years if someone has a question they can still see that history if needed.
Also rail networks require far more staff, and cost a huge amount to maintain. Trains have very large economies of scale, where the cost of journey rapidly come down with large volumes of passengers. Flights don't benefit from anywhere near the same savings when scaling up.

I hear you, though i can understand video makers' point of view; they are often at mercy of YT algorithm with no heads up, no recourse. Also quality content is being slowly edge out by attention grabbing mental pollution videos, actively promoted by said YT algorithm. That is one semi stable source of income for them that wont be pull from underneath them.

So I accept those ads as necessary evil. And I support few creators via patron.
The solution is to lower the cost of electricity. Why is nobody talking about this?!? I jest...

16 pence / kwh is pricy I think. Thats around $0.2/kwh whereas the US average is around $0.13... so around 50% more expensive in UK vs US.
There is a fair bit of my search that has moved to search which I don't think there is any advertising dollars in at the moment.
Thank you for the feedback!

To compare with Learn You a Haskell, I wanted to provide a different option / way of grasping the concept with, hopefully, examples that are relatable to some people more than LYAH. Having a few different explanations of the same thing is not a bad thing in my eyes since different things click with different people.

Regarding Monoid article -- it is sad to hear that since my goal was to provide something that would be unlike the "mathematically-abstract" posts. It has plenty of examples and a rather long exposition, and I am not sure how much more it is possible to improve it without losing any meaning for the word "monoid".

Semigroups and monoids is a rather awkward moment there, I didn't manage to find a perfect way to cover that. But, to be honest, I did mention what a monoid is plenty of times, and I did mention what an identity element is several times as well. So a careful reader should be able to imagine what a semigroup is if necessary.

Anyway, thank you for reading the articles and pointing my attention towards that. I will for sure look at that part again. :)

i lived with my mother in law for a short time when i was between apartments. she would occasionally go around the house and unplug all of my devices in the early mornings before I got up. this was originally just the xbox connected to the living room tv, but if I had my laptop plugged in (work or personal) it would get unplugged too. i don't know if it was a petty "power move" (pardon the pun) or if she genuinely thought the standby mode appliances were bleeding her dry, but she's a senior electrical engineer so she should really know better.

i was considering confronting her and putting in a kill-a-watt and paying her directly the couple bucks a month my standby devices used in power, but i figured that wasn't worth it.
My 9700K desktop draws 45-50W (excluding monitor) when idle. Main usage is:

- GPU at about 11-15W

- Fans on motherboard and case 7-10W

- Disks (1 HDD, 2xSSD): 5-10W

- Peripherals (keyboard, mouse, headset, ...) 2-5W

- CPU 5-15W

I can imagine a scenario with additional peripherals, beefier GPU, more PCI cards, more disks could absolutely reach upwards to 100W.
Maybe this is different based on where you are, I'm in the UK and get emailed about different Angular contracts every few days, it's in use everywhere here.
This is first level ignorance. Which is super amusing when coming from folks that otherwise pride themselves on reading long and dry manuals.

PowerShell has aliases. And it comes with a ton of them already defined, they're even listed in the command help page. Get-Content is gc. Heck, Get-Content is even cat.
It's just basic energy physics. Making something hot or cold is real work. Same with moving something or producing light. But light is extremely "cheap" compared to the rest. Computing data or rendering a video game isn't real work and would consume no power if it wasn't for the inefficiency of current flowing through the chip making it hot.
Can you give an example of a query that won't work with this demo?

Yes, for mindless short dopamine clips with large diversity of topics it is great.
We build and maintain a lot of Rails applications, with several of them almost a decade old. We have to keep them up to date, but Rails is stable and mature and this process is fairly easy. We come across a lot of web apps written in other ecosystems, using frameworks that were popular just a few years ago and have now been mostly abandoned. Or we get bit by an app that is a few years old and now has dependencies that are completely dead and core to the application. This isn’t the case with Rails. It is just as actively developed now as it was 10 years ago, and we are confident that it’ll be just as actively developed 10 years from now. Due to the fragmentation of these other ecosystems, even though the community as a whole may be larger, finding a stack that you can depend on for a long time can be a huge challenge.

Yup, the Basho folks were/are very good about that. BTW hi, we've quite likely met, though I don't know which Basho alum you are. ;) And yes, even I was a pretty late entrant to the HA game. I never worked on Tandem systems, but I worked with Tandem people at the job I mentioned, after having worked with both Stratus and Sequoia systems previously. Those were all FT rather than HA, but the point remains that work on making systems survive failures through redundancy goes back much further than the OP mentions.
A nice side effect of people doing this is that, depending on where you live, you might be able to obtain these older, less power efficient devices for relatively cheap on the used market. Of course if you can barely afford electricity buying them is probably not a bright idea, but for someone with e.g. their own PV system it can be a great way to save some money while also reducing the amount of e-waste going to landfills.

Even better, this is not limited to large power hungry appliances. You can build a surprisingly decent gaming handheld out of an old flagship phone with the help of rooting and some hardware mods [1], basically taking advantage of the low resale value of Android devices.

How would you make a logic programming system?
And if the heat goes into water, it needs even more power because water is notoriously hard to heat up.

At one point I owned many appliances that leaked heat, and I think I learned to estimate how much power they drew simply by putting my hand on them and feeling how hot they were. I'm not sure I have that superpower anymore. (Obviously it was never that exact, because it depends on many other things like volume, material, isolation, etc. But you can get fairly close for common household things – between a finger and a few heads in size, surrounded by air, plastic case.)
