That, and it's not as if the microwave will explode the instant you turn it on while empty. It'll take a few minutes before the magnetron overheats.
> The beginner question is, why don't we use triangle waves of square waves

You can think in terms of complex exponentials, and the use of complex numbers makes even more sense when you know the differential equations can be solved by polynomial methods, which naturally leads to complex numbers.

However you can also answer "why sine waves not triangle/square waves" with a geometrical answer. (This is how I learned it at school, before I knew about complex numbers or differential equations.)

A property of sine waves is that their sums and products are also sine waves or simple combinations of a small number of sine waves.

The sine wave shape persists. This neat property is unique to sine waves, and you can think of it as a type of symmetry.

For example, in the simplest cases: adding two sine waves with the same frequency and different phase produces another sine wave with that same frequency. Multiplying two sine waves with different frequencies produces the same as a sum of two sine waves, having the sum-of-frequencies and difference-of-frequencies.

Doing so with any other wave shape results in a different wave shape than you started with.

A lot of audio and radio signal processing depends on this property, and the way sum-of-frequencies and difference-of-frequencies works for every sine wave component at the same time. Our whole concept of a radio "band" of signals that you can tune into comes from it.
I don't think the price was anything to do with it, we would be having the same discussions if it was Microsoft instead of Apple.
I said "censored or banned". Enough people are getting censored and they are moving. A lot of people that were conservative talking heads that were banned went on parler as that really is the only alternative that is getting traction at the moment.

So I am quite sure that there is a good bulk of people that are going there for those reasons. In anyevent it feels that a line has been crossed.
The issue isn’t really the paper (although one can argue that any single use item isn’t ideal), paper coffee cups contain a thin layer of plastic on the inside to prevent leaking, which prevents them from being easily recycled or biodegrading naturally (which also isn’t possible in a landfill). A minority of recycling plants actually has the capability to separate the paper from the plastic, but this is not time or cost efficient and so it’s easier to just throw it out.

Also, some places do brew or mix in a paper cup first, some will brew directly into your cup.
No, it's not.

These are specialized RF mosfets that cost hundreds of dollars a piece, and you currently need at least four to come close to the output power of a weak consumer microwave. The power supply and control and protection circuitry is also exotic and expensive.

A 2 kW magnetron costs six bucks in quantity.
This has legs. Adulthood has been a major disappointment thus far. I can say, without condemning myself, that I can no longer pursue happiness. Happiness is to found in moments and at the bottom of a bottle of beer, the rest of the time is mild stress and contentedness with ones lot and working on my goals without pomp or self adulation.
I have major depressive disorder, but I take Selective Serotonin Reuptake Inhibitor (SSRI) type medication, so my mood is kind of stable even despite the pandemic.

If you feel depressed, but did not managed to go to a specialist yet, I suggest you try it out because it makes a huge difference.
Zephyr = winning!

(except for the dumbass name, but could be worse, like Deb-Ian)
I don't think it's so easily arguable.

1. What you've written looks quite similar to the lenses approach.

2. I disagree that having nested records brings no benefit at all. What about when the types are generated on the backend so the shape of the model never goes out of sync across that boundary? For a non-trivial size application, I believe it's cheaper to use code generation to derive the type definitions, JSON encoders, and JSON decoders than it is to manually write all of it and try to make sure everyone on your team is disciplined enough to always make those changes.
The temperuture of the coffee will drop quickly, so I wonder if it would not resist to water consistently heaten for 2 hours or if it will fall apart after 2 hours if it contained hot water (that would be bad if you forgot your coffee on your desk).
Whenever I am forced to do surveillance based "authentication" (where they ask you all those questions about your past), I pretend to forget everything I know about my own life and just answer the questions using web searches (eg what city is some popular street in). I reckon this is a good way to avoid confirming any data that they only half know. So far I have not failed to "verify" using this technique.
Em... Eric had a disaster PR moment, while Sundar is just turning Google into another IBM.
God - we are all in the same boat. I have a 4.5 and a 1.5 year old. I can work 2-3 hours in the morning and then I have to push all my work to late evening and I stay up till 1 am completing before waking up early to help with cleaning, cooking, and then caring for the kids.

Can't wait for daycare and montessori to re-open :(
Why is that parasitic? If you provide a gas station and the truck drivers find it cost effective to refuel there, that sounds symbiotic?
But I use the 0% figure, so it is how much the company paid and not how much I get. If you count stock appreciation then a simple senior engineer can make 400-500k or more, but people don't really count that.
(Edit: Cut a response about the Mongols here bc I felt it came out a little snide. My understanding is the Mongols had no writing until Ghengis Khan, nowhere near the written culture of the chinese, but don’t know we’ll enough to argue the details)

> Military techniques that work transcend culture.

Material culture, ie no guns or steel armor. Military technique is highly contingent on the society and technology that gives rise to it: the army is always in some fashion a mirror of the state. For example Fire in the Lake is a really fascinating analysis of (in part) why transplanting western military practice to south Vietnam (as ARVN forces) failed while the Viet Cong flourished.

Ignoring that requires reducing military knowledge to contextless aphorisms like “decapitate the command structure”. I’m open to seeing evidence, but I’d be shocked if the Inca actually never thought of “kill the leader”.

I’m not saying that military history isn’t valuable or important. Obviously it is. My point is that the transmission of practice and the study of history are not the same thing. Calling the study of military history the decisive factor in military history is a strong claim that calls for strong evidence. Just identifying having a highly developed material culture with having greater access to historical knowledge doesn’t cut it.
Should every company that relies on Equifax be blamed for that one as well?
Afghanistan is the longest war 'undeclared war' in US history. Invaded for one reason destroy AQ (and Osama), and then simply stayed for no real sensible strategic purpose.

The war there will of course not end the country has been consistently at war for 50+ years pretty much. But the US portion of it will end, as the Soviet one did before.

P.S:

Where did you serve in Iraq?

How good was your understanding of Iraq politics back then? How aware were you of the different fraction in Iraqi politics and who was fighting who and why?

That was before all the COIN ideas, so I assume there was little education. Considering you were a Ranger you might have had more insight.
Only the government can use force openly on you with complete impunity.
This is true, but truly the customer's own benefits are being compromised here. They can obtain better effectiveness at lower prices and push their margins, but procurement policy is not something companies want to mess with too much.
It's also how they apply the same procurement policies to equipment purchases and software subscriptions. Some of those forms I don't even have a clue how to answer since it's so irrelevant.
I have certainly experienced many awful things in life, but I have not become depressed. Maybe I am just resilient, but I don’t think I am that unusual.

It is interesting that the response to my post has been to vote it down to oblivion. I posted hoping to see if the 2/3rd clinical depressed number is just a self selecting aberration, or HN really has become this bad.
> the UK and France deserve at least some of the "credit" for Israel's status

Definitely. I forget France's influence, but the UK literally granted them the territory without regard for the people that lived there already.

> I also object to it being seen as just a "forward operating base." For most of history the region has been highly prized as the crossroads of Asia, Africa, and the Mediterranean.

Sorry, I was being too simplistic. It is a very valuable geostrategic asset in many ways.
Doesn't seem to work on older phones, I've had to make the jump to VLC.
We are not talking about control here (two toddlers - 1.5 and 4.5 here). We are talking about diaper changes, cooking, feeding, putting to bed, online classes, entertaining them because they can't be outside with kids their own age, tantrums, and usual baby stuff. Doing work full-time and taking care of babies full-time is leading to a lot of depression and loss of concentration on the work-front.
No, you can directly rasterize to the screen buffer:

However, you’re limited to the CPU’s (relatively) mediocre processing power. This is exactly how some of the raycasted game engines were built, though:

And, if you look at open source raycaster engines, they’ll use either Mode 3 or Mode 4, usually with a background enabled:

How many user applications actually fashion a sandbox that is non-trivial to escape with those protections? I struggle to think of any outside of the more popular browsers. The Snap and Flatpak sandboxes are good case studies in the practical limits of Linux sandboxing: it’s rarely effective without designing your entire app around it because the way most applications interact with the system was never designed for it. X11 probably being the most egregious limiter, followed by no standard trusted file access UI.

On the server, there’s a reason Amazon built Firecracker and Google built gVisor instead of just using the Linux sandboxing primitives. I think calling them “industrial grade” is pushing it when they’re rarely used as the first line of defense against code that is expected to be actively hostile.
It is a big part of the reason that service providers and consultants exist and command the fees that they do. They are implicitly signing up to be the fall guy if the project doesn't go well.
That's a good point, but the world goes through something like half a trillion disposable cups per year. Even if 99% of them are used exclusively to store hot liquids in cars for over two hours, that still leaves 5 billion cups per year that we could usefully replace with these.
Imagine that the company is paying 25% extra because of these policies.
Any prior golden age you might care to look at was unevenly distributed. That was the case before the internet took hold in the 90's, during the rapid economic growth of the 50's, in the Renaissance, the heights of the Roman Empire...

Yes, that does not mean we shouldn't look back on the things in the past that were good & now are not. But if a wholesale reversion to a past time was possible, we would still find the golden parts of that earlier age to be apportioned to some, but not others.

Another consideration is that while I don't like life inside a panopticon, its absence in the 90's meant those of us fortunate to be "golden" simply had less awareness of those who weren't, hence the false impression that perhaps there was a lot more gold everywhere.
No. But every company that gives information to Equifax could and probably should be.
Yes, sorry, not a native speaker
When You Don’t Want to Be Here, but You’re Too Afraid to Die
I don't believe I said at any point that printf isn't useful, there's just reasons why you don't use it.

Heck, even on the PSP which had a fair amount of horsepower console logging was a blocking read and we avoided it unless necessary because it would throw off all sorts of timings(and drive the frame rate in the toilet).

In the microcontroller space, 2/3rds of what I'm debugging is cycle timing sensitive. I2C or SPI sequencing and there having a logic analyzer that I can cross-correlate with actual external signals is so much more useful. They've gotten cheap enough these days that it is sometimes just easier to connect one to a spare pin and toggle that pin based in the internal state I want to track.
"2006" should probably be in the title of this submission. But it and its comments are interesting.
What is this supposed to show?

I see a lot of iCloud and Software update stuff in there.

Nothing malicious from first glance.
I am sure the complexity is intentional.
As with anything, it is what you make of it. HN has a stereotype of MBA students that doesn't always hold up to the real world (though not all stereotypes are wrong).
Ya that would be really helpful. I've picked up bits and pieces of vim over the years. Recently, I even installed vimium on Chrome and the vim extension for VS Code in an attempt to get better at it.

It has been quite effortless to delete or replace words or lines but every time I've tried getting more adventurous with it - say, surround every line of text with double quotes etc, I end up finding the commands unintuitive or hard to remember.

There's also an issue with my older muscle memory of `CMD+Z` which works on a different stack than `u` and `CTRL+R` and I end up messing up my code.
Do you have any links to read about "developing 3 generations in parallel"?
Actually not really the case. The US never really relied on fossil fuel from the Middle East in the last couple decades.

That oil was important for Europe and most of all Japan and China. And that is still the case in many ways. Of course now the US maybe doesn't want China to have cheap oil anymore.

If it was about securing US oil, war in Venezuela and Canada would be far more sensible.

And even then the US didn't need to do anything, everybody would have happily sold the US oil without the need for any kind of war or US troupes of any kind.

The US increase intervention was required because of policy growth, where the US wanted an ever increasing control over these places for things other then oil. Once the Soviet Union was gone, the US started to dream of reshaping the the region and integrating it fully in the the US system.
On Twitch's point specifically, they claim:

Your suggestions are not inherently unreasonable but most of them amount to ways that a out-of-sorts normal person can make themselves feel quite a bit better, and have very little to do with steps that might help someone with severe clinical depression.

That long list of things might help someone (especially given "drink mostly water" tends to suggest "don't drink very much alcohol") but it's unlikely to contain anything particularly first-order for a genuinely depressed person, and some of the "don't think too much about your health" suggestions seem actively mischievous.

I've known a couple teetotalling regular-schedule folks with great exercise habits etc. etc. who have carried out their praiseworthy and abstemious schedules right up to they moment they stepped off a building or bridge, in one case leaving behind a couple small kids.
It would be helpful if you provided some context to why you developed these utils, like what exactly were you doing, what were the pain points, why haven't you adopted any of the existing tools, pros and cons of your approach, etc.
Emacs mostly has problems with external language servers because its plugin model is archaic and brittle to a large extent compared to that of say VS Code. It's also far more flexible but with power comes responsibility, and I've found Emacs extensions far more likely to interfere with each other than in less composable editors. You don't need Nix to fix this problem.
I buy 1/2 on bags of ground habanero pepper for like $5 a bag and put it on all my lunches and dinner. If you can see the powder on your food, it will be blazing hot.

I end up drinking about a liter of ice water and have to pause my eating several times. I often end up shivering after due to the sweating and the ice water.

Yum!
you're quite right about this.
although i would say that we do actually store memories in our bodies. this is where extended abuse and trauma really take their toll on people. think about shell shock in veterans. they train and train for combat. then they see combat and the trauma then embeds itself in the 'muscle memory' of training. then something random happens but triggers the muscle memory and the memories come flooding back.

same for say, abused wives. say they get out of their situation and meet a nice person. then one day that person gets angry that the dog shat in their best shoes and they have a fit which reminds her of her previous relationship. the memories come flooding back.

depression is the same. for me it's been a recurring failure of academic and meritorious achievements. in our society not achieving these things is like a frying pan in the face when you want to do something that requires experience say. sure, I've learned to duck, but everytime life swings a frying pan at my face [being fired, not meeting qualifications, being considered unreliable/unintelligent etc] all those old memories come back. so you end up dodging one frying pan and get hit by another, as if there were some kind of compound interest frying pan abyss. my metaphor for the muscle memory of depression. eventually you just take the hits cause what's the use in trying to dodge the pan?

i will say this though; after being on disability for a decade there is something bitter sweet about the rising levels of depression brought on by covid. while i don't wish depression on anybody whatsoever, and hope one day we'll find some perfect somatic solution to it, misery really does love company.

I'm not sure how to get the depression out of the muscle memory, but i do know we need to do a better job of getting people away from their trauma.

Apple single-handedly killed off the Safari extensions ecosystem for extremely dubious reasons. It would be inaccurate to say that they have locked down macOS to Mac App Store-only apps, but even if you ignore the embedded platforms the concerns about locking down macOS are extremely founded even as Apple repeatedly says they aren't trying to do this.
ever since the pandemic started, at work we've had a a chat channel for "socializing" with each other. One day someone posted a topic. Something like, "Tell us about where you grew up". And the head of security immediately replied and said, "let's talk about something that isn't a common security question".

I admit that I think that was 100% unnecessary, expecially in this situation, to put the kibosh on the conversation. But it made me realize how insane it is that something that is a common "get to know you" type question (tell me about where you grew up? (street, school etc) Tell me about your parents? (maiden name)) are also a common "security" questions.

Also, side note. I NEVER use real answers to those questions. I treat it as an extra password and store it securely that way. No way I'm going to turn my mother's maiden name (easily searchable if you know my full name) into a password!

This is a nice essay but I think it misses 3 key points:

1. FTC returns are predictable. The returns to taking an unbeaten path is anything but. Further, how will your peers and the world view you as CEO of New Idea Inc vs. L4 at Google?
2. Prestige is a cheap correlate, and thus substitute, for aptitude. Outside of Tech, verifying aptitude and fit is like trying to pay with physical gold whereas prestige is like paying with Amex Platinum.
3. Consulting and Finance offer exposure to a swath of otherwise opaque industries and opportunities. This appears to be especially true in industries driven by culture fit and trust. Why do many e.g. biotech companies eschew an MD/PhD CEO for an ex-MBB 'professional CEO'? Because the CEO exists raise money and that requires immense trust and penetrating opaque networks.

Perhaps returns to prestige are overrated, but I'll take the prestige 10/10. In my experience, the previously closed doors suddenly open themselves for you.
Isn’t it usually both? My compy’s on-site has multiple coding sessions and multiple design sessions.
I hate to be that guy but 2020 has been one of the best years of my life. My girlfriend and I moved out of our 600 sq/ft apt Oakland apartment for Colorado. We now have a good sized house with a large garage for wood working and my new found love of tig welding. It's honestly more walkable/bikable here than Oakland. My car is unlocked with things people could steal in it right now and I don't have anxiety about it.
I've always thought that Apple would do well to have someone on staff to give the things they make the "Hacker News" treatment.

You’re looking at the wrong pool of potential employees. On my team of ~40 people, I am the only one who was born in the U.S. They hire from all over the world and will pay what’s necessary to import top talent from other countries.

Also, 200,000 sounds way too high for total number of technical positions at these companies. There are a very large number of people working non-technical jobs there as well.
Centralized control means centralized pressure points. The idea that this is "not the way we operate" is laughably upside-down coming from any corporate entity.
