Ask HN: How do you learn something you can't practice?
It seems like I learn best when I practice.

Learning about chess? Play the game and practice tactics.
Learning about programming? Do some exercises and projects.
Learning about cooking? Do some recipes.

But what about economics or philosophy?
How do you learn something you can't practice?
Wasn't this a MacBook feature at one point? That behavior sounds quite familiar to me.
The hacker news base and similar forum & social media 'nerd' spaces are no longer their largest customers. They've moved away from power users. Most people now using Windows, Android 12, iOS, don't care and only want a working machine that goes to the internet, plays netflix/disney+, and works with their social media websites/apps. It's about convenience instead of possibilities and tinkering.
As someone who's worked "in the trenches" of Famicom chiptune and emulation (especially the FDS chip), either this page has an unusually large number of inaccuracies, or the previous articles also have many inaccuracies but I don't know enough to point them out:

- The FDS's sample amplitudes are 6-bit, not 8-bit. FamiTracker doesn't let you set sample values above 63, and the topmost 2 bits are docmented as ignored in https://wiki.nesdev.org/w/index.php/FDS_audio#Wavetable_RAM_... and not written in the nsfplay emulator (https://github.com/bbbradsmith/nsfplay/blob/master/xgm/devic...).

- "A Gameboy wave is limited to, at most, 32 values. (17 in the sample above)" Where did you get the number 17 from? Is that because a 32-sample wavetable has 17 distinct frequencies ≤ Nyquist (0 through 16)? To my knowledge, the GB wavetable is hard-coded to 32 values, no more, no less. And in the screenshot, it is 32 samples long (as expected) and has 14 separate steps.

- "By the standards of Yamaha synthesizers, you might call this a “one-operator” FM synth." No, it's called a 2-operator FM synth, since the carrier wave counts as well. (The YM2612/2608 have 4 oscillators, and 1 to 4 of them can be carriers. This doesn't make it a 3op to 0op FM sound chip.)

Sorry, no tips for you to follow MI startups
If a hypothetical criminal valued breaking bitcoin at a significantly higher amount than the profit derived from mining, then the criminal would just attack the network and win. Remember that I'm not describing the security of a PoW network, I'm describing energy consumption and only assuming that individual miners will not mine unprofitably.
The whole premise that this might be something in everyday use one day seems completely flawed. Even at the 1cm cube of physics it’s huge compared to GPS and it uses incredibly expensive materials.

If you’re a nuclear submarine or stealth bomber it makes loads of sense. For anything else I don’t really get the point.

I worked at two FAANGs then moved to Michigan about two years ago, just outside of Ann Arbor. I get contacted by a decent number of recruiters but I'd estimate only about 5-10% of them represent companies with a Michigan presence.
I spent two weeks or so working at a government contractor. I put my two week notice in almost as soon as I’d started, and I permanently swore off the industry.

There were some genuinely good, smart people working there, but the culture was such that I’d be very surprised if they shipped a working product in 5 years time. If they did ship it, it would be an awful thing to behold.

I don’t know how to fix this issue. But from what I’ve seen and heard, the best minds (other than the rare altruist) stay in the private sector. It pays better, and there’s just so much less BS to deal with.
Sweet as, feedback acknowledged.
I can understand the reasoning behind it. But it's still unfortunate.
My apologies, I'll rein it in.
In the mid-90s I used to repair PCs. Customer brought PC in where left mouse button did not function.

Easy. Replace mouse. NOPE.

OK, software issue. Reinstall mouse driver. NOPE.

OK, deeper software issue. Replace HDD from working PC. NOPE.

OK, replace RAM? NOPE.

OK, replace motherboard and all add-in cards. NOPE.

At this point we have a different HDD, motherboard, CPU, RAM, video card and mouse. Still left mouse button doesn't work. Mouse moves fine. Right button works.

Only thing left is the case and the PSU.

Replace PSU. Left mouse button works perfectly.

I recommend learning how to focus on one thing at a time. A laptop with windows in full screen mode works for that. Close every app you don’t need to get the immediate task done. People are not very efficient at multitasking.

I went from three monitors and two computers to a 13” Chromebook laptop, because I traveled and worked remotely for six years. My focus and productivity improved, so did my customer satisfaction and income.
> The rate should probably adapt dynamically, like pick a target number for the gini coefficient (or whatever) and ratchet the tax rate as necessary.

High tax rates on the super rich are kind of this political pablum, where everybody buys into the idea of it because the thinking is Zuckerberg is going to pay all the taxes and then you won't have to, but it doesn't really solve anything.

Zuckerberg is never going to spend that much money on consumption. Not even 10% of it. Not even 1% of it. How could you even do that? You only need so much food, so many houses and jets.

The problem is that his wealth gives him control over "Meta" and therefore everyone. But that's the same problem even if he's only the CEO. It has little to do with what percentage of the company he owns; somebody's got to be the CEO. The actual problem is that the company's too big. You can't fix that with individual income tax rates.

And if you try, the amount of resources that will get poured into tax avoidance will just eat you alive. I mean it already does. Billionaires already shield most of their wealth from taxation whatsoever, so what does it matter the rate?

Fix the thing that causes billionaires to exist, namely market concentration that causes the founder of the winning company to be a billionaire instead of there being a thousand competing companies whose founders are all millionaires.

> I'm completely untroubled by so-called double taxation. Squint and it looks like a VAT.

This is completely the opposite of VAT. The whole point of VAT is that it isn't double taxation -- if a business buys wholesale for $80 and sells retail for $100, they only have to collect VAT on the $20 difference and not the whole $100, because the wholesale seller already collected it on the $80.

To do otherwise creates a massive incentive for vertical integration because if the wholesaler buys the retailer outright they wouldn't have to pay it twice. And so it is with corporate dividends.
The problem with this piece is that it spends more time discussing a word change that how to make interviews more like actual discussions.

The word "boss" was original chosen because it avoided implications of a power dynamic between the boss and the worker. Centuries later, it has re-acquired the same connotation.
Oh, I know that glass can be recycled. That is not a question to me. What I'm less sure about is whether it can reliably be recycled without being reforged. I'm also not sure whether glass recycling is much better on a net carbon front than manufacturing. I'm sure it saves the cost of silica mining, but then there is the cost of shipping the returns and getting rid of impurities . . . it would be an interesting thing to know.
I do the opposite. I do not eat breakfast and I'm completely fine. Dinner is around 6 p.m. so I go about 18 hours without food every day.

I only have coffee in the morning and the only calories in that come from a bit of milk I take in it.

I don't necessarily feel hungry at lunch time either. If there's something going on at work (prod issue, in the zone) I might find myself at 2 p.m. without having eaten.

Sometimes on the weekends I will have a leftover pancake w/ jam for breakfast. What I noticed is that if I've had that, I usually crave food again at noon.

Not sure where you get your information from. It says it right here, you can use "local computer" for training your model, and that includes AutoML. There is no cost to using Azure ML.
I don't think the e-waste is economically relevant. The environmental cost of Chia is much higher than the cost of cleaning up its e-waste. It's also much lower than than the cost would be if Chia were protected purely by energy.

To be more specific, the dominant cost is the opportunity cost of disk space. Producing and using a drive can't be accounted for as "e-waste", otherwise you'd be forced to claim that drive efficiency doesn't matter because more efficient drives produce just as much e-waste.
It's a cute story but one that is utter nonsense.

Anyone who is above junior level system or network administration should be able to instantly tell, on point #2 alone. If they don't, they do not understand the basics of TCP.

1)Wave propagation through copper wiring is a bit more than half the speed of light. Strike one.

2)His mail server sends a SYN which is acknowledged by an SYN-ACK back. His mail server does not know instantaneously that the other mail server is accepting the connection; it has to wait for a reply back. A mail server that is '3ms away' even assuming speed of light transmission and no switching/routing/transmission delay would be ~250 miles, not ~500.

3)A mail server does not instantaneously reply to a SYN packet, so there's delay there. Strike three.

4)There are multiple routers involved (at least two) and especially circa 2002 routing and switching probably accounts for a significant amount of delay. Routers and switches tend to be store-and-forward; they receive the entire packet, an interrupt is generated by the NIC, a routing decisions is made, the packet is shoved into the buffer of the outgoing NIC, etc. That doesn't even cover firewalling. 3ms delay through multiple circa-2002 routers, firewalls, and switches is not believable.

5)Transmission delay. Packet take longer than just "distance divited by the speed of light" to arrive somewhere. Given typical LAN/WAN connection speeds of the day, packet transmission delay would be a factor. Ie the time it takes for a complete packet's bits to be transmitted.

6)Jitter. Even the slightest jitter would have wildly affected his testing. Just 2-3ms of jitter (if we follow this guy's calculations) would result in undeliverable mail to almost anywhere, yet he claims mail within the radius was reliably delivered. The campus network (particularly inter-building links), internet uplink, backbones, other network, and other mail server all have jitter that combined would easily exceed 2-3ms.

I also find it extremely difficult to believe that sendmail on SunOS defaults to a 3ms timeout and lacks a sane default when not specified; 3ms isn't remotely sane even today, much less 2002. Anything less than 30 seconds would surprise me. Lot of old software had very long timeout values because of how common slow links and systems were.

This looks like a viral story told by an unemployed sysadmin to get his "I'm looking for a job" message out.

If he truly had the knowledge commensurate with 10+ years as a sysadmin, he knew it was bullshit, and I think he might have been very cleverly looking for places where technical knowledge was lacking and thus he'd either be the smartest guy in the room or have an easy time of things.
IMHO skip the word 'sexy'. It's a business tool. I see it's already removed from the website headline.

On the login page it says 'Welcome to Insite' and 'New to Product Path? Sign Up.' Isn't the company called DashMinds? The three names confused me https://www.dashminds.com/tools In the blog post https://www.blog.dashminds.com/post/new-app-insite it's introduced as 'InSite', not 'Insite'.

The contact link in the footer doesn't work, on about-us the email points to productpath.com but there doesn't seem to be a website on that domain. Privacy policy says getproductpath.com

Productpath is a waiting list, not launched. Insite was annouced 5 days ago as beta. Terms of service is only a couple of days old. How does that fit with "500+ Companies, 300,000+ Quizzes completed" claimed? I don't trust it. Many links don't work (e.g. logo top left), missing content, boilerplate pricing and faq, only available in the US. Little I see suggests 500 companies use the service.
agreed. Also, taking titles that you don't qualify for is a red flag to me.
So imagine this setting. You set up multiple learning stations / activity centres where students can independently learn on their own. These learning stations are analog and digital. They contain some tests that are mandatory and can be taken at any time by the students. To perform the tests the students go to one of maybe five workstations in secluded areas in the classroom that can be watched by the teacher. After each day the teacher can analyze the grading and can be reasonably sure nobody did cheat.
All great questions, but I suspect the answers are classified.
I recon that’s what said about solid state gyros and accelerometers, vibrating structure gyros were initially developed for the military now they are like a $1 a pop…

Thanks for the advice, joining a rocketship is what resonates the most with me to be honest.

Happiest I have been was when I was sleeping 5 hours a night maximum, always on the road visiting different customers' offices to work closely with them. Had an offer about a year ago to leave my current position and build out the data science team of a rocketship but didn't want to leave my team on their own.

The ‘inactivists’, tangling up the climate crisis in culture wars
> Which is noble, except they do this entirely by ripping off other people's R&D and undercutting lots of people including smaller players.

Most smaller player are also ripping off "other people's R&D". The only difference is that they charge 5x, 10x what Behringer charges. An extremely small number of people are doing new stuff.

It's even worse with guitar stuff. There are several Tube Screamer clones that sell for 250, 300, while the original is still under production for 120. The constant complaining about Behringer's one that costs $20 is petty and privileged.

No to mention Behringer has some pretty cool original designs. The Deepmind comes to mind.

Poor people also deserve to make music. You can bet I'll keep supporting them.
I grew up in Metro Detroit. Moved to California in 2015, and while it's been fun... I'm moving back to Michigan (Downtown Detroit/Brush Park) next week.

I certainly used to feel the lack of VC activity in Detroit, but that is also what made the startup scene so ridiculously scrappy. I truly believe constraint breeds innovation, and I miss that aspect of the companies I worked with and helped start in Detroit.

Theres a lot to love and hate about California, but for me the dealbreaker was the price of housing. You shouldn't need to be a Founder with a phat exit or Senior Engineer at FAANG to afford a house... While I myself could probably swing it, why would I want to live there long term if that's the case? I miss having friends and neighbors from different walks of life. Theres a perspective you get from being connected to the greater ecosystem of humans, and that is increasingly evaporating in the Bay. Pretty soon it may only be tech people left. Most of my friends who weren't in tech left long ago.

On a different note, what really excites me about Detroit at this moment is the vast opportunity to build and shape a city rising from the ashes. A friend of mine is starting an eVTOL company and getting a 12k sqft hangar at Detroit City Airport (class charlie, international airport) and it's going to cost less than my SF apartment. Theres actually another eVTOL startup already there that has some hangars in the same building. It's ~10 minutes from Downtown.

Ford is building their EV/Self driving HQ in Corktown. GM is going to be manufacturing their EV's (including the Cruise Origin) at the Factory Zero 10 mins from downtown.
Theres a ton of VC moving into the area, and an unbelievable amount of housing developments (~$200 million in brush park alone).

The momentum in Detroit is astounding and exciting, and when I'm ready to start another company it'll absolutely be there.

As America Falls Apart, Profits Soar
There are a lot of highly terrible government contracting agencies out there who charge enormous fees and who knows who actually does the work given the likelihood no one even validates any of the work. Suck our taxpayer money out of the system and leave trash in the wake.

You'd think an agency as important as the FBI would verify who is working on their systems, but probably no one did.

This article was really relatable. Not that I’m an entrepreneur, but thinking that I’m unique in the problems I face.

Actually, I still do think that. For my entire software dev career, I’ve mostly felt unmotivated, disconnected, slacking off, avoiding, procrastinating.

Covid pushed me over the edge. Now after having taken a year off, I’m starting to see the value of work (duty, service). I’ve been driving Uber, which has been fun. I like the pace and the people and driving.

But I’ve never had a coworker who was able to give me useful advice, as none of them seemed able to relate. So, I continue onwards solo to figure out how to develop a healthy relationship with work…
Utterly tasteless joke, but I upvoted you anyway, because I have a soft spot for offensive humor.
> Mac and Windows also have problems with such setups.

Lol no.

I have issues on my Windows laptop when I try to use 2x 4k + one 2k display display from the single thunderbolt connector, due to Dell TB19 dock allocating too much bandwidth for the DP and HDMI ports (while 2 of my screens are USB-C) regardless of the resolution they use or the number of screens connected.

But with just 2x 4k USB-C screen, it provides both power and display output over a single cable, both in Windows 10 and 11.

And if I connect the 3rd screen to the dock after connecting that single cable, everything works.

FYI, since it is a dock bug, the same thing happens in Linux.

> Not to mention having displays with different resolutions and refresh rates

Lol no!!!

My displays are different: the 3rd one connected by DP is an ultra wide CHG49 - so neither the same frequency, aspect ratio or DPI.

Yet it still all works fine. Linux users are weird when they start assuming just because I use Windows, I must have an experience as bad as theirs.

Even my terminal (mintty) is far better than the best Linux has to offer - and I'm not even talking about AHK that lets me control my keys in a language far more advanced what the few configuration xkb or xmodmap offer.
If you don't trademark it, it's not your name, because you have no right to disambiguate form anyone using the same name.
It was more of a half thought out idea than something concrete, currently drawing a blank on how the network would communicate the tracking information outside. I also seem to have misremembered various things about Ethernet tagging. :(

> It would prevent the reflection portion of these attacks (a bot could only reflect traffic back into its own IP block, not towards an arbitrary global target), and knowing which networks originated the traffic would enable other countermeasures.

That makes sense.
> I'll go further, why is it punishing customers allowed?

Because it isn't disallowed.
It’s not too difficult to see.

Eg : 2^3 x 2^5 = 2^8

Explicitly writing the powers as multiplications :

2x2x2 x 2x2x2x2x2 = 2x2x2x2x2x2x2x2

So multiplying powers of the same base is just adding the exponents.

Logarithms are the inverse of exponentiation.

Log2(N) counts how many factors of 2 are needed to multiply together to get N.

So Log2(2^x) = x

As per above example :

Log2(2^3 x 2^5) = 3 + 5
This author does not strike me as a honest or forthright narrator. I can see why an editor would nix her quotes.

Maybe checkout Advent of Code instead. Less mathy, more fun (IMO).
Agreed. I was sloppy in my previous comment, but what I wanted to explain is that we started with good old static imports, but needed a lot more dynamic stuff (heavily customizable deployments - onprem, dev, SaaS prod, etc)

Python can do this, but we had to accept that yep, we need a lot of elbow grease to be able to use regular libraries plus have a highly environment and request dependent "stack".
