Learning physics is not the same as learning to do physics. If you want to learn how to really do it, you need to work problems.

This means you to learn the techniques, and you need problem books, with solved examples, that you can work through on your own, or with a small group. This is absolutely critical. This includes both complex mathematical calculations as well as back-of-the-envelope calculations.

Moreover, while textbooks are great references, nothing replaces a good video lecture or presentation, that gets to the heart of the physical concepts without being overly technical. n
And remember that physics is fundamentally an experimental science. It is not just advanced mathematics. Even if you yourself are not an experimentalist, you need to understand the basics.
Optimistically, we could flip this on its head and say that a marker of privilege will be driving an ICE vehicle. It'll become enthusiast-driven rather than necessity.
I'm working on the ALU right now :-) So far, it looks much more similar to the address adder than I expected. The same basic structure, but with control signals that adjust how the inputs are combined, so you get multiple operations.
The modern version of that is thunderbolt naturally.
I encourage you to be more quantitative. We trade money for safety constantly. Every time you drive your car to work you do so, and likewise every time you buy a small car.

As of a decade ago, incorrect airbag deployment killed one person for ever 7 lives it saved. Nonetheless, they were mandated by law for many classes of cars, and were purchased voluntarily for others. And this was the right decision. They could have spent thousands of dollars per unit to get the mistake rate even lower, but that wouldn't have been worth the money.
For most people they're personally investing their energy in what they consider more important issues. We all only have so much energy to go around, and this obviously comes low on GP's list. This is in the same vain as online advertising or buying food from supermarkets over local stores.
It's a long article of a dude trying to convince others that he's not responsible for his own actions and it's someone else's fault when he does something wrong.
One of the first programs I wrote on the Amstrad was a random number driven matchmaking program that would pair up boys and girls in my primary school class. I guess that was more titillation than love though.

I created a web based adventure in about 1998 for a girl’s birthday (featuring the A-Team, the cast of Friends, Peter Stringfellow, Alf from Home and Away, and many other celebrities whose photos I could find easily). I don’t have a backup, archive.org only had it partially and it was full of absolute filth so I wouldn’t really want to resurrect it.

In 2011 my wife (different woman, despite the excellence of the above) and I were struggling for baby names so I made a Mac app that used Bayesian stats to find out what kind of sounds and spellings you liked. I later polished it up and released it on the Mac App Store to some small but satisfying number of sales.

My son (named via the simpler algorithm of my wife deciding on her favourite name) is now 9 and I write code for/with him. Yesterday we wrote an app to show random arithmetic problems for him to practice on, in GAMBAS which is excellent for kids learning to code.

My dad wrote programming books in the 80s and we grew up around computers and learned to code quite young. I guess if anything I’d struggle to separate programming from love even if I tried.
that is awesome. So awesome maybe it should be the default.
I don't believe that's a reliable source, sorry.
It’s great seeing our game engine pop up in posts like this!
Would be a fun open source project to find the cheapest board that can fit in the box, ideally take some components (speakers, WiFi) and have similar functionality like controlling music, home devices, setting timers. I’d try to contribute if anyone is working on topics like this.
The Color of Pomegranades is a film that stuck deeply in my mind. Another russian was director is Tarkovsly and his The Mirror is also deeply abstraact and very visual.
Thank you for doing this. 8086 was my very first chip and I used it to run my qBasic "hello world" program on an IBM PC XT. Back then, I thought I was somewhat smart for being able to write a simple program, without giving much thought to the amazing work that went into creating these chips and related technology. I see what you're doing with reverse engineering and documenting as a very important part in preserving knowledge which is otherwise very likely to be forever lost due to IP, copyright and corporate policies. Thank you for your work. I hope you'll find strength and energy to continue.
it's absolutely a good business decision, because you place too much value in the bad pr. there is almost none.

facebook has done a crazy number of bad things. a few nerds like me hopped of, and total their user base grew. but nerds like me never had facebook in the first place.

linkedin used your password to log into your emails and download them, then spam people in your contacts with invites, coming from you. then they sold user data to facebook. now their app was caught copying clipboard data from your phone and computer. no one cares, except for me who has a harder time finding work -because i'm not on linked in.

giving you bad flight prices when you're looking for flights? that literally happened. but surprise -you don't remember.
Or you can use some basic math, and calculate how much tire/breaks wears(loses original matter) per 100 000 km and how mach of gas a car burns for the same distance and compare these numbers.
Opening Medium in an incognito window has so far away been enough for me to get past that.

Also, are we due for a snappier phrase than "requires registration"? Loginwall, registerwall, accountwall?
Gerard 't Hooft, Nobel laureate in physics has a list of resources to learn theoretical physics here:

https://www.goodtheorist.science/

Basically, whenever you become a physicist, especially a Nobel-prize-winning theorist (this even happened some to me during my non-theoretical PhD), you get a bunch of emails from cranks that believe they have "figured it out" without ever having engaged with the centuries of work and results that we are building on. So he made this reading list that he requires people to be familiar with before he engages with them. All the information you need is available and easily accessible and he just curated it into a full course.
Is this sort of "tu quoque" fallacy acceptable on HN? And you're talking about events from two decades ago. What relevance do they have today?
Hello there. This looks interesting, but I think that from a promotional standpoint, your website needs screenshots or a video of the user interface for your program. It's cool that you can make this music with it, but I would like to quickly get a feel for how your program is used.

IMO, most people will want to see that before they invest time reading documentation or downloading and installing your software.

Just my two cents! I hope this is helpful.
Are you sure? Where's the citation to back that up?

What I remember are many products released around that time by Google, et al that were sold to us as: we're making gobs of money off of our core offering (e.g. search + little text-based ads), that we can afford to all this other stuff for the benefit of humanity. So much was sold as "making the world a better place". The other sales pitch we got amounted to, "don't worry about it, we'll monetize later."

Nobody was up-front in those days. Which is why not a month has gone by where ToS or Privacy Policy changes need another click to accept to keep using. The frog was certainly slow-boiled.
> once the bootstrapped company has that, the would-be copycat would be playing catch-up to a no-longer-bootstrapped company

This counts on the bootstrapped company tapping outside capital once they hit their stride.

If it refuses to do so, it would be trivial to copycat and flank them in markets they haven’t yet captured, thereby boxing them in and reversing the first mover advantage with a scale advantage. The only protections against this are IP and true, technological moats.

Back button highjacking. The article not worth it.
I love how these onions are sold under fifty different fictitious brands, many of which are using highly misleading labeling and packaging. Maybe I'm just old fashioned, but it seem dishonest to sell California onions in a bag that prominently announces "UTAH ONIONS" and doesn't say "California" on it anywhere.

Yes, their organizational structure and the lack of trust that sometimes flares up between teams really shows in the integration. Which is, of course, exactly the level where most customers live. IAM used to be exactly that but they centralized that cross-cutting concern and it's improved a lot.
> One of the chefs needed 10 years of experience before they would let him do the egg sushi.

That only ever struck me as extremely pretentious, to be perfectly honest.

The chef in question needing 10 years of experience before they would let him do the egg sushi strikes me as essentially the same harmful mentality the Japanese have toward productivity, thinking that clocking in as many hours as possible equals productivity (regardless of what you got done in said hours).
Same with -The Thirteenth Floor", one of my favourite movie, make sure you don't read any spoiler about it though.

Nexts on the list:

Moon

Ex Machina - I personally have no issue with nudity but I wish there were less of it in that movie because I know it turned a lot of people off

The Green Mile - not quite changed my view, but reinforced it

Westworld 3rd season (first 2 seasons revisit themes from above movies, they are good but not necessarily new themes)

Breaking Bad - I tend not to like series and this is a really long one, but it really does make you question things.
Option + Click

And

Command + Option + Shift + Click

Works on most default OS things you can click on. Reveals a whole new set of amazing functionality.

Example: Doing so on the bluetooth icon on your menu bar, gives you the debug option for you to reset / restart bluetooth module.
Snowpiercer

Most people see this movie as a very on-the-nose example of class struggle. But I see it as a commentary on how we humans build and interact with the very system that we collectively create to sustain ourselves as a species. The system always has its apologists, supporters and opposition, but deep down all but the most extreme zealots understand that the system has to change with time or fail, and the longer it takes for change to occur, the worse the inevitable failure will be. It ties in nicely with what Nassim Taleb says about fragility of rigid systems.

In the movie the system is represented by the train and its architect. All people on the train are grateful for what the train has provided them: safety from certain death outside. The poor at the back of the train are constantly threatened and preached to by the train loyalists how important it is for everything to stay as it is, that the train is eternal and will be there forever as long as they obey and believe. But as it becomes apparent that the loyalists are lying and things don't seem all that rosy with the train, the poor start to push forward, for information, and ultimately, change. As they go forward in the train they discover that the wealthy passengers have fallen into either hypernormalisation or a drug fueled apathy. They either believe so much in the train that they can't see how it could ever fail, or they know that it will inevitably fail but have given up hope to do anythin about it - perhaps facilitated by their own relative comfort (why jeopardize such comfort for an uncertain, risky change?).

After watching the movie, it struck me how we're perpetually living in an unsustainable system, but we avoid the abyss by constantly changing from one unsustainable system to another.

> The US has killed thousands of civilians in its countless wars in the last decades.

> Just think of all the stuff that happened after 9/11 with Guantanamo Bay.

Name the people out there, and then we try to discern if they are terrorists or civilians.

I'm sure you haven't been under authoritarian regime once in your life, have you? I suggest you try living in Iran or Palestine for a while and then, with your first hand experience at hand, we can discuss who kills civilians by thousands.

If you haven't noticed, native Hongkongese have been begging the US to intervene recently. They know exactly how it feels when an authoritarian regime takes freedoms away from you.

Primer: Earnings Reports and Financial Statements
"Here is an excellent study with both theoretical and empirical results showing the efficacy and importance of universal mask wearing, even when cotton masks are used (PDF download is in the upper right corner)"

This is not a study of masks. First, and most importantly, it assumes that masks work, and makes a model of a world in which they work. From the methods:

"A gradual increase in mask wearing was modelled using a linear increase in the proportion of individuals randomly allocated with a reduced rate of transmission. The factor by which β was reduced was conservatively set to 2."

And for their second model:

"Varying degrees of mask effectiveness are modelled by the mask transmission rate T and mask absorption rate A, which denote the proportion of viruses that are stopped by the mask during exhaling (transmission) versus inhaling (absorption), respectively. We set T = 0.7 and A = 0.7"

So when you make a model that assumes masks reduce infection by half or more, the model shows that infections are reduced. Shocking.

Then, when they say that their models have a "nearly perfect correlation" with reality...they don't actually compare their models to reality, nor do they calculate any correlations. They simply quote a bunch of numbers they cherry-picked from news sites (with no controls or normalizations) classifying countries into "mask-wearing cultures"...which is so obviously silly that any halfway rational person should see right through it. This is a "paper" only in the sense that it might someday be printed on paper by someone who was gullible enough to believe it.

Regarding your comments on the researchers I mentioned: perhaps you should spend more time reading the articles you cite, and less time judging well-established scientists who disagree with your opinions.
It wouldn't make sense in a world with infinite and free food, but that is not the world we live in.
It's absolutely fascinating to read these replies! We have a very diverse set of people here.

I had no idea that people didn't drink milk on its own. Apparently some Europeans don't. I eat cereal mostly to drink milk. If Oatly was a good substitute, I'd probably have started using it. (I haven't tried it yet.)

340ml is 0.08 gallons. That's consistent with "about a bowl of cereal."
For an anniversary I built a (password-protected) site which showed a search box. When my wife searched for terms related to her, it would bring up pictures, stories, poems, etc. I'd had a bunch of friends secretly submit their own media so that there was a bunch of content! It took me probably a year to put everything together and come up with all the terms, but she loved it!
> Compared to 0% mask usage in Norway.

That is factually incorrect.

I see several people wearing masks, at least in Oslo. Both on the subway, but also people working in grocery stores etc.
Minority Report is thought provoking. The movie takes place in the future. The police have a new "precrime" division where they stop crimes before they happen.

Makes you think about how we apply AI today that makes decisions that can affect human lives.
Android phones are constantly stealing your data, I'm not sure why a processor vulnerability would be cause for alarm when your entire OS is a data exfiltration and surveillance platform.

Has HN just turned into Reddit? Do people really not care that people's privacy is being dumped down the toilet? Google is known for shit like this. They even scan your emails and alert you when bills are due. Shit like that is not ok. Don't fuck with my privacy unless I opt in.

I answered this line:
>>> My point is that US companies have to pay more because more things need to be taken care of by the individual instead of it being socialized to different degrees.

the point is you get all these benefits and on top of this you get several times higher salary (I'm from Europe myself originally for what it worth).
I think that’s sorted now. I had some weird issues when the last OS dropped but not seen it for months.
That drink is a latte, but a latte isn't that drink. A latte is made with two ingredients: espresso and milk. Anything else is a variation.
Hmm, I thought I remembered reading something to the effect that this was currently possible, but now trying to find more information about it I'm coming up empty.
"Reduce Motion" in Settings > Accessibility.

At some point in the last 8 years, Apple changed the animation for how a window becomes full screen. The default behavior is to expand while simultaneously shifting the window to the right, or conversely expand while the desktop shifts to the left.

Enabling "Reduce Motion" eliminates that behavior, and the full screen window fades in and out instead, which personally I prefer.
One way to discover this is to open a menu, then try hitting modifier keys.

Some functions will change, and some of the functions with shortcuts will add the modifier.

For example, open the Apple menu and press and release Option.

Some menu items that say "Foo..." which means they will have an "are you sure" dialog will change to "Foo" which means they will not confirm.
There’s a great, cheaper alternative to lawyering up when your participation is optional: don’t participate and don’t discuss anything.

I applaud any effort to improve communication within a team, and haven't tried this specifically, so take my criticism with a grain of salt.

My concern with this approach is that it relies on us to be self-aware of our idiosyncrasies and limitations. There are aspects of myself that I do think I understand well and could be well communicated with the tool like this, but I suspect that I might be blind to the more problematic aspects of my own personality, and that this lack of self-awareness exacerbates or is that the root of the problem.
Small knit pick, but speech to text isn’t lossless. How someone says the words has a lot of impact on the meaning of those words. It’s possible Amazon doesn’t care about that lost information but that is a completely different conversation.
The main thing is consistency, as ovens/cookers are temperature controlled. Other bootleg options are available:

Household clothes driers can get hot enough as well, but not all of them do.

Cars on a hot day can also get to the desired 140-150f+ range.

Concrete is not an ideal construction material if you are worried about reducing CO2 emissions.

It also follows that intercity travel should be restricted, for the same reasons.
Yes, if you want to have a pleasant earth to live on then feckless, wasteful travel should be restricted. This does not have to be done by rules -- simply charging people the full cost of their trip would place it out of their ability.

No, the outside temperature is rising, thanks to the freedom-loving, brave self-expression of car drivers crawling like ants to and from their places of consumption to their places of production.

> Why do you think Google would sell pii? It doesn't make business sense.

In these discussions, "selling PII" is sometimes a short for "providing a service that allows targeting ads based on PII without actually releasing PII itself to the service users", which is only a little less bad.
