Here I'll date myself: I remember this as "diode with a gate". Back when we did circuit diagrams with stencils, you had the diode stencil which looks like a triangle with a line on top, and then with the electrical stencils you had "decorations".

The intention was to put down the original symbol on the paper, move the decorations stencil over top of it and then add the required decorations. It's why diode symbols look like this: https://imgur.com/a/0tSLV7O (notice "step recovery diode").

The "lightning bolt" isn't a lightning bolt, it's a hint that this diode is going to have a very sharp "snap off" in the waveform. See: https://www.electronics-notes.com/articles/electronic_compon...

OK so why do we have a seperate decorator for a diode? Can't we just have a pocket full of stencils for diodes? Space was at a premium back then. It goes back to daisy wheels and typeballs: https://en.wikipedia.org/wiki/Printer_(computing)#Impact_pri... You would have one position for "diode" and one position for "decorator" and the printer would know when it got one ASCII char it would print the diode, then send whatever the thin space is to advance the print carriage a small step, then print the decorator.

Someone should be able to find a daisy wheel or typeball dedicated to circuits and bear this out.
I have a feeling if OP had read some of the papers surrounding Daniel Kahneman (and the works Kahneman cited) he wouldn't be so sure about mankind's rationality.

It's like the vast majority of experiments on the subject ends up with "and then they proceeded to use their intuition and who they like more to make their decision".

Also, I think it was "Classical Rhetoric for the Modern Student" that also said that logical arguments are the weakest kind of rhetorical arguments since basically anything else is more likely to convince people.
> But I do know you can travel to NK and see for yourself.

My understanding is that tourists in North Korea only see what the government of North Korea wants them to see.

Here's one (admittedly potentially biased) source that claims as much:

"Tourist travel to North Korea is only possible as part of a guided tour. Independent travel is not permitted. If you are not prepared to accept severe limitations on your movements, behaviour, and freedom of expression, you should not travel to North Korea." [0]

> Selectively restoring data only for certain rows is super hard.

What's the right way to structure your data here that would make restoring more straightforward here? Is this backup/restore scenario niche or they should have designed for it?
The cost of server was lower and fixed (buy it once), the cost of datacenter is MUCH higher (minimum 500 users, pay per year).

Which is even more amusing when you realize Server has been Datacenter with a fake mustache for years now.
This is a bummer, but probably a reality. Perhaps some kind of LCD type tech could make for it to be more digital/less big metal moving around.
But who needs that?

A typical SLA precludes that by specifying the remedy for noncompliance with the performance measure. Only if they fail to apply the remedy is there a material breach. For a month-to-month SLA, this limits liability to one month's subscription, as agreed in black-and-white.

Customers that demand service level agreements often fail to recognise that they cut both ways.
I always use the mute switch on my microphone and not the mute switch in software.
The book's calls to action are as such:

> Know all the possibilities, think about the worst-case scenarios, and then find ways to eliminate the intolerable ones.

> Diversify

> Put deferred gratification ahead of immediate gratification so you will be better off in the future.

> Triangulate among the smartest people possible

Each of these have varying degrees of paragraphs detailing their nuance, but they all come back to the point of making personal decisions to navigate a decline rather than changing the system of decline.

> We can assume based on the article that the wife is the one doing the dishes. So, that means every time the husband leaves dishes out he is making more work for his wife than if he just put his dishes in the dishwasher.

Not necessarily the reasoning that it may be re-used is valid, also it may be that he would eventually put it in the dishwasher when the dishwasher is ready to be run. They could probably have come to an agreement that there was a specific spot that one singular glass can chill out (maybe not even in the kitchen).
ITT: armchair therapists whom I suspect have never cohabitated with a partner for multiple years.

Sincerely,

Armchair HN therapist
When you are the only one paying for apartment, hobbies and school, since those "minor" things are out of her mind she has all the time and energy to ngaf about it and bloat her ego, manipulate and gaslight you into thinking you are not good enough boyfriend... husband... father...

These are classic manipulation tricks of narcissists.

And the fact that she allows herself to engage in a 6 hour argument during workdays knowing or not caring that it will absolutely fuck up your entire focus and ability to concentrate for days and bring you closer and closer to burnout and not being able to actually work speaks volumes on how much she cares about you and what she is after in these relationships in general.

She doesn't want an equal she wants a servant. She wants a slave. Both physically and emotionally. Every second... She defines the rules of the game and you obey and play. It's a given. Your whole life with her is her play...

Ugh... I say F that life.

You need to celebrate the day you dodged that bullet. Not everyone has a mental courage to throw those human-sized parasites out of their lives.

People can live 40 years blaming themselves for not satisfying narcissists enough, they reshape their whole identities and morale in the process trying to shove themselves into a shape that will hopefully satisfy ever evolving demands of a narc and never getting satisfied with their lives in the process or becoming self-enclosed philosophers but in most cases just plain miserable...

They finally divorce, while the narcissist will happily jump onto the next victim berating and destroying the personality of the previous victim ignoring the fact that that person's whole life and identity was a sacrifice on the altar of the "wants" of a literal demon.

It's a vicious cycle.

Narcissists should be pariahs in any social circle. Their ability to deliver huge amounts of damage and mess somebody up mentally for years is so underrated that I believe whoever comes in contact with such a person has an obligation to not only immediately jump out of that relationship but also warn others about that person.

Just like coming in contact with COVID you tell others around you about the danger, you should do exactly the same about narcissists.

I wish you all the best and hope now you are more than well equipped to spot these creatures.

And don't forget to transfer the knowledge to your children to break the circle.
I think their application is grid scale and you can scale across hundreds of batteries to provide the throughput you need. I don't know how I feel about having a small molten ball of metal inside the hood of my car. Turns my car into the most dangerous gusher in the case of an accident (for those who aren't familiar, gushers are a gummy like candy with juice inside).
Argument forced on you for hours of time during work hours because your partner wanted it now sounds horrible. She is an entitled narcissist who has no respect for you, your time, and your work. Congrats on dodging a bullet by moving out.
It seems at least recent versions of the Tesla Model S and X have seperate computers for their infotainment system and autopilot [1]. That wouldn't have helped out the guy from the article, though, I believe he was manually controlling it.

If Teslas have their infotainment (running in React Native?) and motor control/drive by wire on the same computer, I'd be shocked. That's awful.

why does there need to be profit where there is no natural scarcity?
I agree. I look at every JIRA killer and think we could maybe move and nope...they're missing something we use. In many ways JIRA is like Excel. On the surface it can appear easy to replicate for a single user, then you realize every user uses 10 different features.
Wanna know something even crazier?

There's a radio station here in City1 that has the same morning show hosts as the radio station in City2. They literally do two shows, or pre-record one, I'm not sure. They talk about local City1 news and such, so they try and make it relevant and local. But it's crazy! Are there no radio personalities in my city they could have hired?

Bonkers.
Are you sure it was LSD?
As the article points out, using collected client data is problematic, because some errors will often be undetectable, as in numeric data. And in general, you would have to control for bit flips somehow caused by software.

I wonder whether a SETI approach would be useful here. Allocate, say, 1MB of memory. Fill it with some known bit pattern. Periodically check the memory and look for discrepancies. Do this once an hour, on 10M devices, and that is a LOT of monitoring. Report discrepancies along with time, location (including elevation), hardware and OS information.

I would think that this approach would provide a lot of interesting information about when and where bit flips occur, especially when matched against information on solar and atmospheric events (as in the article). Perhaps sensitive hardware and OS environments would be detected. Even completely negative results would be interesting: no bit flips observed would suggest that purported bit flips elsewhere might have other explanations.
I'm not surprised that there exist folks doing macro work on M43. And I'm not surprised that you can find such people in the corresponding forum on dpreview.com. :) I was not making a universal claim of nonexistence.

Hmm, interesting. I didn't know that
Why not Devanagari then? This Europe-centric point of view bother me.

Sure: As I mentioned in another comment, I'd add markers to enable arbitrary super and subscripting.

However, the question I responded to was asking what specifically people were missing in practice, and the examples I gave are things I personally would have used if they had been available.
> Sure, but how often do you have them on your person in time to take candid photos?

Totally bad argument in justifying phone cameras. If you are having the expectation of getting photos of similar quality as shown on the page, my question is, how often do you have a high quality ring light on your person along with a stable tripod?
The Logfile Navigator (https://lnav.org) is a TUI for viewing log files that can be configured to process structured JSON files. It has quite a few features, like filtering and color coding.

The documentation for writing a format file is here -- https://docs.lnav.org/en/latest/formats.html

The format file tells lnav what common fields are in the log messages and how to format them into plaintext for display. Here's an example configuration for JSON logs -- https://github.com/tstack/fullsail_lnav_config/blob/master/f...
There are ways to avoid your transactions being tracked. Coinjoin transactions, purchasing a miner for non-kyc bitcoin, payments on the lightning network, etc

Also, they can do all of those things, but you can setup your private keys in a way that your family will still have access to the bitcoin even if you are killed
I think the logic here is that it does not:

A) Need to be done now
B) Need to be done by the husband
C) A & B

If it's just a water glass, I'd not be surprised if the husband intends to (or would) reuse it from its position on the counter, hence the entire dishwasher->cupboard cycle is superfluous from the husband's point of view.
Theoretically I can stand up a mining operation in my apartment. That means that the 51% attack (as long as it can be detected) can be thwarted by folks at the grass roots level (as long as they actually care). Am I wrong about this?
On first and second read it sounded like you were saying it -should- be on page 83. My bad!

I read it to see if they were going to say of course not, because the iPhone exists, but it turns out no, so the next step is to point out the iPhone exists and Apple, out of all the [expletive deleted] companies in the world, needs no saving.
" serial communication is almost always faster than parallel communication."

Its a bit more complex than that. The PC serial port's top speed from the PC->printer/etc was significantly faster than serial at the time. Its only in the reverse direction that there were problems (note comment above about using the control lines for device->PC). And that is by design, the ISA/PCI/RAM/etc buses were parallel, and despite many of them becoming "serial" are still technically parallel (ex: PCIe) because its far easier to gang a bunch of serial data lines together and deal with said synchronization (which is frequently fixed by the hw design/trace length/etc) than attempt ever higher serial frequencies.

And that is fundamentally the problem with trying to use serial as a high speed peripheral interconnect (see HDMI vs displayport for an nice example of hitting walls). Eventually one runs out of bandwidth and the solution ends up being ganging a pile of them together into a... parallel bus. Its why thunderbolt will perpetually be a loser when it comes to GPU attach/etc. A serdes at N Ghz+PAM can just be put on a motherboard x16, and each line is synchronized at a higher level instead of each bit. Ex: PCIe 6. Same with RAM buses, the latency and bandwidth advantages have basically kept them parallel buses (using per line serdes kinds of tech), despite various serial memory standards.

Another example is ethernet where QSFP's are just x4 serial lines.. aka in parallel. SAS x4, etc.

So, these days like RISC/CISC its hard to be 100% correct calling some of these technologies pure serial or parallel.

We didn't invade after the Cuban Missile Crisis; in fact, Cuba remained closely aligned with the USSR until the end of the USSR. If Russia merely sanctioned Ukraine, nobody would be discussing this. Your rebuttal is facile.
in theory, shard your customer databases 1:1, job done. alas, in practice, many SaaS compromise this two ways:

a) overwhelmed by creeping featuritis, each customer's data has relationships to global tables, and

b) they backup their entire database cluster in one snapshot

and there maybe other gotchas for restoration, like relying on denormalized views and caches that have to be rebuilt. they may also have erroneously assumed that data protection's main value driver is whole-of-system disaster recovery, which can lead to pathologies such as "we don't have a single-customer restoration tool".

this is not a niche scenario
I'm surprised how many pro-cryptocurrency comments I see here on HN. I would expect people here to see through the hype and technobabble.
>There is no innovation in cryptocurrency

What other technology makes use of an immutable ledger, like you said?
Element was available from 2003-2011--are you talking about "certain demographics" who wanted the reliable automobiles that Honda made during that time? So weird.

That is in addition to offering AWD, stick shift, stow-able rear seating, better MPG, vinyl interior instead of carpet, removable moon-roof, none of which the Astro had.

Rule of Succession – Estimating true probabilities with few samples
Nice article, but the intro is a little lengthy.

I have one remark, though: If your language allows for automatic differentiation already, why do you bother with a neural network in the first place?

I think you should have a good reason why you choose a neural network for your approximation of the inverse function and why it has exactly that amount of layers. For instance, why shouldn't a simple polynomial suffice? Could it be that your neural network ends up as an approximation of the Taylor expansion of your inverse function?
F numbers have exactly the same meaning across different sized sensors: the ratio of the focal length to the aperture diameter. The size of the sensor does not even enter into the definition of the f number.

>For example, f/1.5 on the iPhone is equivalent to f/8.2 on a 35mm camera

This is a meaningless statement unless you specify what sort of equivalence you're talking about. I assume you mean to say that they're equivalent in terms of depth of field and in terms of the total amount of light gathered for a given angle of view. This, however, just goes to show that the 35mm camera doesn't have much of an advantage for macro photography. If the 35mm camera has to stop down at least to f8 (which it probably will, to get sufficient depth of field) then it won't gather any more light than the phone.

The basic point here is that for a given angle of view, you can only gather more light than the iPhone if the iPhone has depth of field to spare. Otherwise you can only gather more light than the iPhone by sacrificing depth of field. This is because both the total amount of light gathered (for a given angle of view) and the depth of field (for a given angle of view) are determined by the absolute diameter of the aperture.
I hear you and I'm afraid of the answer. I am extremely conflict averse.

I sit at the dinner table hoping to talk every night. She's busy scrolling facebook. Yes sometimes I end up on my phone as well, but I actively make the effort to be there to talk.

>you are undervaluing your partner's contributions

I am a big believer in legitimate praise and even giving compliments to strangers. Though obviously stearing clear of flattery and fakeness.

Once in a while she does find the energy to do something. I always notice and say something positive.
Forth works quite well for problems that fit its stack-based model, but that's not every problem. For instance, having to manage and permute data on the stack is often more awkward than doing the same things in languages that use ordinary variables. And working with only a single stack at a time, it's not clear how such languages might express parallelism, which is otherwise a very natural expectation for a functional language. Even things like complex data types, pattern matching etc. get needlessly awkward.
I like the feature of my video conferencing software that popups up a helpful overlay when I start speaking while on mute. It lets me know I'm muted in case I don't intend to be and reminds me I can press and hold space to temporarily unmute.

Obviously it's listening white muted to do this, but it seems legit.
Lol what if by spreading crypto knowledge in totalitarian states, you give people in those states a viable way to preserve their income and assets in a way that no other asset class can? Imagine someone trying to protest or escape a regime imposing capital controls on citizens such as North Korea or Canada. What if, those citizens could simply memorize or encode a 12-24 word phrase that could preserve their net worth against all forms of tyranny? What if by doing so, you create the conditions that lead to the eventual collapse or reform of said totalitarian state?
