Theres a few more types than that. But thats the gist of it.

"online" is generally a double conversion UPS.

These are generally the best for clean power to the electronics. Since its always supplied by the battery. Its also often one of the hardest on the battery.

Line-interactive are probably most common. They are pretty solid, but since there is a delay for the cutover, surges and really dirty spikes can make it through to the equipment. So say a lightning strike or REALLY bad surge on an overloaded generator can get through, whereas on a Double conversion it may just trip the fuse or breaker. Also running a whole home or standby generator on these line interactive can make them trip constantly since the generators often dont

A) run at 60Hz (ie: mine runs closer to 63Hz)

B) run with a pure sine wave

You can get inverter generators to help with this. But thats a cost too. And otherwise the solution is to "de-tune" the UPS sensitivity.

I de-tune this on mine. Its been fine, running on gennys during the rainy months for hours and every know and then...days at a time.

I have had to swap out power supplies more often..But even then, usually thats after like...5+ years of runtime.
In the case of Uber, "marketing" is often just direct or indirect subsidies of pricing (aka, selling $1 for $0.50). Its a questionable business model, though it appears to have worked for them to some degree, the rides segment of their business doesnt seem to be as reliant on that spend as it used to be, and is actually profitable.
Standby UPS topologies like the APC Back-UPS lines keep the battery out of the loop until a loss of power from the AC input is detected, at which point the inverter kicks on the the transfer switch takes the feed from there.

This is a design choice from APC, money is on the control electronics being powered off the battery meaning a dead or missing battery means the entire unit is non-functional. Making the unit resilient to this probably costs as much as a line-interactive unit, however, so you might as well just tell people to get a better unit than make a middle-ground solution.

I can answer this as I’m currently on a two-week holiday and I have a small homelab running at home.

First and foremost: fire alarms. Buy them, and use plenty of them.

Secondly: let your neighbors know you’re on vacation. This implies a certain amount of trust with your neighbors, but it’s good to be on good terms with them for more reasons than just this.

Thirdly: I get notifications if a server goes down or a fire alarm is triggered.

With all this in place, I don’t worry at all. I may be somewhat ignorant or oblivious to certain risks, but in general I trust the safety net I just described.
This fails because we only have one formal kind of payment - money - and in a monetised economy, nothing compares with it.

Money solves one problem - how to get people to do things that may be useful to others which they wouldn't otherwise do - but causes much worse problems in return.

The most obvious is money is such a riotously inefficient way to decide what is and isn't genuinely useful, especially collectively.

OSS doesn't really solve the usefulness problem. It's good at producing software that's appealing to people who like using and tinkering with OSS software - but no one else really cares unless it's handed to them inside a product which has been assembled to be useful. And even then it's about the product, not about a largely imaginary "freedom" which is inaccessible to most users because it specialised skills, advanced knowledge, and plenty of free time.

This doesn't make it useless, it just gives it a different domain to operate in. There's some overlap, but there are many potentially useful projects that don't happen because they don't appear inside either the commercial or the OSS circles.
> I suspect corporations don't want limit software engineers to those with licenses

It comes down to money, which includes liability. I suspect licensing won't ever happen in software unless law suits increase and licensing becomes a deterrent, at which point licensed developers will cost less after factoring for risk assessments. There are all kinds of unintended benefits for everybody that come from limiting negligence, which pays for itself. As a counter argument who benefits most from allowing the hiring and practicing of negligent developers?
what are your thoughts on https://www.youtube.com/watch?v=OwqIy8Ikv-c
Paying bribes is illegal; but facilitation payments are legal.

If you have an official who is refusing to perform their job, or taking inordinately long about doing it, then it's legal to pay them to do it. As long as you're not influencing their actual decision making process, i.e. causing them to overlook actual legal deficiencies in your paperwork, then it is legal.

It's called the facilitation payment exception to FCPA. Obviously one intending to make such a payment would be well advised to discuss with their lawyer to make sure it is indeed within the scope of the exception.
Bash script to debootstrap a minimal bootable Debian/Ubuntu system
Since installing Linux on old machines and using them as routers/servers is my hobby, I find myself installing on a regular basis. Since the default installations (even if you choose "minimal") tend to install a lot more stuff than I really need, I always found myself looking for ways to make it even leaner. So in the Debian/Ubuntu world this lead me to using debootstrap quite a lot (I also use --variant=minbase to make it even more minimal).

I did have a checklist written down to do things like partitioning, bootloader installation and network and other configuration with small snippets of bash but this still tends to be quite a long and manual process. That's why I recently decided to put all of that knowledge into a complete bash script so that I could get the installation done quicker. While the debian-installer with preseed route seems no longer viable since it looks like Ubuntu are discontinuing it at some point and I do tend to use both Ubuntu and Debian.

So, https://github.com/kvaidas/debootscript is the result.

Not only is this useful for under-powered machines, I also used this on machines at hosting companies after getting burnt several times by their custom "improved" images/configurations which break stuff at the worst time possible.

Some nice things about it are: having less stuff installed so possibly a smaller attack surface as well as a smaller amount of updates. Less diskspace usage so quicker and smaller images/snapshots/etc.

Of course this is just a bootable base system with networking and not useful right after the installation but since networking is already available, it's possible to use your favorite config management tools and existing playbooks to shape it into something actually useful - without doing stuff manually.

Note: this does turn off Install-Recommends and Install-Suggests so you might find some dependencies don't get installed automatically and you might need to intentionally install some dependencies.
Then the engineer designing the bridge should probably choose a different beam supplier who can stand by their product.
Apparently in PK these days government competes with agents on service and will take same money and deliver DL to your house
I think that this advice cannot be generalized. There are companies with large development teams spending staggering amounts of time solving problems they don't have and probably never will and companies burning through whatever goodwill they can find to extract maximum profit by throwing garbage, buggy, and incomplete software out into the market "because agile". Almost no one gets this right. I think the two sides feed off each other by each pointing to the other as an example.
When I'm testing locally with a trivial site, those favicon 404 requests bugged me when checking the log. I'm also a little bit obsessive about keeping my pages small. This resulted in me going down a rabbit hole of the GIF spec to see the smallest inline blank favicon I could create. I ended up with:

<link rel="icon" href="data:image/gif;base64,R0lGODlhEAAQAAAAACwAAAAAAQABAAACASgAOw==">

Putting that small line in my HEAD tag gets rid of those annoying extra requests, and results in no favicon (it's just a totally transparent image).

If interested in the format, I put a gist up at https://gist.github.com/billti/81d4b601c9022ba3655a3a03873ca... with the small node.js script I wrote to generate various examples. (You can see more examples and links in the comments in the top if interested).
A single, middle class income can certainly support a family of four in the majority of the US.

And back in 1970, could a single middle class income support a family of four in Manhattan? Urban centers have always been expensive.
But Google sells services too. If Apple is not making most of its money on hardware, then what differentiates Apple's incentives from Google's?
Do you think they'll simply decide, "We will not track people for targeting ads, and we won't sell their data"? But what if they find that that perspective doesn't actually help them sell their services, because the vast majority of consumers just don't know or care about these issues like HN users do? It didn't cost them much to have that perspective when most of their income was from hardware, but once it's coming from online services, it may turn out that they're leaving a lot of money on the table, which would be very easily made, by being less purist about the privacy issue. Not that they're super-purist now, from what I've heard...

1.4 km is a curious distance. Perhaps they are optics that didn’t make the 2 km cut and are sold at a discount?

I wouldn’t worry too much about the standards. There are lots of optics that don’t stick to the standards, but go above and beyond.

I’m more interested in the use case at hand and if the specs will support the use case.

I've also read both books. It's a good exploration into the minds of spiders and octopuses, if given "uplift".

A recent study I read about shows that spider intelligence is ill-studied but actually holds a wealth of interesting facets. Jumping spiders plan, such as when hunting, and can be surprised. They are also doing elaborate planning when building webs, and make adjustments to strength/stickiness in webs based on failed catches. It's sophisticated tool use. And yet their brains are teeny weeny puny things.

Another novel that you might enjoy if you haven't read is "A Deepness in the Sky", it's similar to Children of Time (and predates it), but told in a different way. Both are highly enjoyable and packed with ideas.
Amazon Renames Twitch Prime to Prime Gaming
I searched for a couple of celebrities, and in one case celebritynetworth.com is the top result, in the other it is the third result.

Both queries show info boxes with the estimated net worth, both cite other pages (no link to celebritynetworth.com), and one showed another number than celebritynetworth.com.

celebritynetworth.com has a robots.txt. This file has no restriction on Google or any other bot.

Each celebrity page seems to have the following meta tag:

<meta name=googlebot content="index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1">

Given the above, it seems like Google is correctly listing celebritynetworth.com high in it's rankings, and using other resources for the info box, which is what celebritynetworth.com is asking them to do.

While it's hard to speculate about what happened in the past, it looks like Google is doing the correct thing now, and that this information isn't actually so novel in general.
I live in a place where blackouts are very infrequent (perhaps a couple per year)

Ouch. Does anyone know where the author lives that a couple of times a year is considered "infrequent?"

Decades ago I lived in a rural area of America where we'd have power outages two or three times a year because of storms. But I've lived in more than a dozen cities since then, and the power has only gone out twice. Once about a decade ago during a tornado, and then again last year when the power company replaced a transformer across the street.

I ask because it's my impression that electric service has gotten much more reliable over the years. There are still access issues where I live now (believe it or not, thousands of Americans don't have access to the electric grid at home), but reliability seems improved. Am I living in a bubble when it comes to electricity?

Yet the economic expansion in the 80’s was some of the highest in the past 50 years.
Exactly! Maybe you've seen them before but what you just wrote are so-called "copatterns". See:

https://www.cs.mcgill.ca/~bpientka/papers/unnesting-copatter...

https://doi.org/10.1017/S0956796819000182

https://agda.readthedocs.io/en/latest/language/copatterns.ht...

Agda even has extra sugar on top for postfix projectors: you could write `myPair .ProjL` (as expression and as copattern). Syntax for pattern-matching anonymous function crucially uses that (yup, we have multi-clause anonymous functions!). You'd write:

introProduct f g z .ProjL = f z
introProduct f g z .ProjR = g z

or

introProduct = λ { f g z .ProjL → f z
; f g z .ProjR → g z }

Note that most languages already have that "codata" thing but it's usually called "record" or "struct".
I'm in my 30s, I've been a primarily web developer for 15 years, and I know there is software I wrote in 2008 that is still running today for processing the rent of 1000s of residents. It has been updated a few times, adding a console argument to automate the process more. It was originally a Bob-O-Matic process. At midnight on the first of the month, this old-timer Bob would launch the application, click one button to load the residents, double check the numbers, click another the button to pull the rent statements, check those numbers, and then click a third button to process the transactions which actually took about an hour to run through, and on occasion would actually crash once a year or so, but it had the ability to pick back up after a crash where it left off.

That was probably my first real bit of production code, it (un)fortunately replaced half a floor of people with one man, who faithfully clicked those buttons every first midnight for the next 10 years before he retired. It was then automated by the couple of South African contractors that replaced the NYC-based app development team.

The company spent about 12 years automating away almost every job except management.
That's odd, because my operating system, available software repositories, and desktop environment are all pretty great.

I don't know if anyone can suggest some tools, but my minor problem with PDFs is that any kind of data table gets absolutely mangled/unusable for cut/paste purposes after creation.

It's like somehow the PDF generation process randomizes the order in which it populates tables, such that selecting by a user later is generally impossible.

Maybe it needs to be interpreted / extracted from the PDF source itself, but average user graphical selection of a table is out the window.

You can't point to the grounding of the 737 Max 8 as a reliable indicator of the cost of regulation because:

1. Arguably this is the cost of regulations not being followed properly

2. This is an extra-ordinary circumstance that is costing much more than a regular plane would cost to get certified and fly (see point 1)

3. You are drastically underestimating the cost to the industry both in terms of reduced customer confidence, hull losses (~$100mil an airplane), and increased insurance premiums if we were to continue flying the Max 8.

But honestly, I'm having a really hard time understanding what your point is. Are you asserting that we should just fly the Max 8 and not worry about it? Are you asserting that airplanes aren't safer now? What are you getting at?
I think that's less on the format and more on the intent. For reports and what is traditionally viewed as "written form", reader is expected to have high tolerance for length and boilerplate.

I see it as the pendant of the "younger generations can't read anymore" critic, where lenghty, rambling and diluted prose is becoming harder and harder to parse and focus on.

On the other side page load speed and attention grabbing metrics are thoroughly studied for web pages and people value terseness, to the point of loathing click baits and endless listicles.
But what is harmful software? Today, while there are arguments about facebook being too addictive, it's really just competition between platforms, it's not everyone's opinion that the software engineers at facebook should be liable at this point for making an addictive algorithm. At some uncertain point in time, there's the possibility that facebook will be sued for the addictiveness and lose. Should that happen, I don't see why the software engineers should be partially to blame.
The article correctly and importantly points out that there are many types of UPS. Most recently, I got a production-grade APC SMX1500RM2U for home.

Another thing to be aware of, if your PC has a PFC power supply, is that it might reboot or have undefined behavior on event of the switchover to battery, unless the UPS is designed to avoid this.
Facebook Financial to Pursue Payments and Commerce, Led by Libra's David Marcus
I was told a saying that in China, at least you know who to bribe to get shit done. In India, you have no idea.
I don't think anyone is against your examples. The issue is WHERE the tax money is coming from and the PROPORTIONS of tax paid in relation to overall income.

Unfortunately right now the middle class is being stuck with most of the bill on a PER-CAPITA income basis. And considering the wealth gap between the rich and the middle class is SUBSTANTIAL, it means we're essentially having relatively poor people (middle class) pay the bills of very poor people (lower class).

When you zoom out a little (and remove irrational emotions about the topic clouding your perception), it's easier to see the disconnect.

> You can argue the same with CD’s but disc rot is an increasing issue.

Why not? I have a laptop with a 4th gen i5 that has VT-x. I've upgraded it to 16 GB RAM and an SSD. For now, it's a Spotify connect player but I'm contemplating running a couple VMs on it too, like pi-hole and whatnot.
This is much harder than it needs to be. But I also don't think agricultural land should be rezoned willy-nilly. Much of India's population (~60%) rely on agriculture. It should be with great thought that private parties should be able to convert the land (not just because it reduces land able to grow food and agriproducts), but also because it can be a way to dispossess the poor. For an example, see the plight of those whose land was taken to found a new capital city in the state of Andhra Pradesh. The landowners were more or less given a good price for their land. However, those who rely on the land - farm laborers and their dependents - haven't seen an improvement in their situation. They've essentially been turned into migrant workers; they were able to work on local land before. This is essentially what the English gentry did during the enclosures. The resulting "reserve army of labor" helped seed the English Industrial Revolution.

Can we comprehend them? From what I've read about it, consciousness in octopuses has to be completely alien to ours, because it's spread out over multiple brain centers, including one for each arm. So the arm is a semi-intelligent entity of its own.

No idea to what extent the article discusses this; part of it is blocked by a paywall, after which it continues about eating moluscs. But just like people eat octopuses, it's entirely possible that alien intelligence end up on our dinner plates before they end up at our negotiating table.

because he gets emails from the unit when it happens.

I had a script in a raspberry pooling my UPS each minute asking if the unit was running on AC or battery, and dropping that info into a file when it changed. I know the software/daemon can also do something like that.
I find it surprising that service panels don’t have more extensive protection features. I would like my main breaker to trip under any of these conditions:

- Sustained overvoltage. Any overvoltage lasting too long to be handled by a surge protector should trip the main breaker.

- Sustained undervoltage. Some devices don’t like this.

- Phase error. A two phase main should detect incorrect phase-to-neutral voltages and incorrect phase-to-phase voltages. A three phase main should also detect incorrect phase sequence. This should also catch some cases of a disconnected neutral.

- Excessive neutral to ground current. In the US, for reasons I personally strongly dislike, every “service” has a connection from ground to neutral, usually in the meter box or the main panel. Various errors can cause substantial current to flow through this connection and can be dangerous. For example, if a house and the utility both have excellent grounds but the house’s neutral feed breaks, all the voltages can be close to correct and the house’s neutral current will return to the utility through ground. This is dangerous and will not be detected by common equipment. (A whole-house residual current detector would satisfy this, too. I think these are used in Europe.)
