A 2000kg car can produce 200hp, or 10 kg/hp. A 100 kg man + bike combo will produce 1/3 hp, so 300 kg/hp. The bikes are underpowered and every bit of extra performance is very welcome.

A bike manufacturer cannot produce a better man, but they can keep optimizing the bike itself and they will keep doing it until even the wealthiest customers balk at the cost. Which is why the best gear is out of reach for most people.

You can easily purchase a bike that is not that heavily optimized - they are $100 a pop in Walmart.

The details of these optimizations are numerous and elaborate, but they are only a consequence of the weight/power balance.

Might makes right with global financial markets: the US dollar is the world's reserve currency because the US will grind your country into paste if it needs to protect the supremacy of the USD.

Tether doesn't get to print currency. If Tether doesn't like it, too bad. Tether can get an aircraft carrier or a nuclear arsenal then we can talk.

Even YouTube premium doesn't get rid of that.
Guantánamo Bay files: Casio wristwatch 'the sign of al-Qaida'
Testing software is important because developers are expensive
LISP and its variants was the introductory programming language at MIT from the 1970s to the 2000s. Partly because they had the LISP/A.I. royalty on their faculty in this era. Students complained they wanted something more modern to get a better internship. They was silly because the majority of students entered MIT having already learned the latest fad language during high school.
What is MAP. That's a really hard term to search for so I'm not finding anything obviously relevant.
My son is 2 1/2 and loves to do jigsaw puzzles but with lego, he seems not very interested yet. Maybe 3d reasoning develops a bit later.. But for around that age or a bit older like 3-4, what sets work best? Simple block sets? Sets that include small lego people? Thank you. I grew up behind the iron curtain and lego wasn’t available until
I was a bit older and we were playing with other things
"It is cheap, basic and widely available around the world. Yet the Casio F-91W digital watch was declared to be "the sign of al-Qaida" and a contributing factor to continued detention of prisoners by the analysts stationed at Guantánamo Bay.

Briefing documents used to train staff in assessing the threat level of new detainees advise that possession of the F-91W – available online for as little as £4 – suggests the wearer has been trained in bomb making by al-Qaida in Afghanistan."
Major changes for Linux /home with systemd?
The number one mistake is thinking that everyone else is an engineer too. They put complexity in the product thinking that users will take the time to learn it. All users want is to have their problem solved the easies way possible. But engineers want to add features because they are cool as oppose to useful. It's a big mistake.
It would be cool to see a follow-up post that incorporates patterns (different marks likes dots and hatches, different densities, etc.) as an additional distinguishing characteristic for areas fills that aids accessibility.
Tether is meant to be pegged to the dollar. It is supposed to be printed in high quantities if high quantities of tethers are necessary to maintain the peg. Otherwise the peg would break and one tether would be worth more than one dollar.

Am I just being thick? It seems like the article has cause and effect the wrong way around. Demand for bitcoin would be expected to drive creation of tethers not the other way around.
Isn't Shah Rukh Khan an investor too in Byju's?

Edit: just a brand ambassador. He's still complicit in misleading millions of Indian kids.

Business model. Gc always pretended to be the place to get your first guitar, even advertised constantly about it. But their business model was service to people buy 100k or more worth of stuff. (schools and large bands) it is bad for their real business to service the little guy, they need to be free should the big spender walk in!

Small shops always gave better service to the little guy because that was their business.
I have been involved in embedded systems for more than 25 years now, and I barely do "pure" embedded development these days. That is projects that comprise only designing a specific PCB hardware, or writing the firmware drivers and top level application for them.

Except for a couple of years I have resided mostly outside of California, but when doing consulting I have mostly engaged with companies in the Bay area.

In the past when I did pure embedded development I had to fight tooth and claw to get rates close to $100/hour, while at the same time iOS app developers or webdevs were starting at $120-$140/hour easily, even after the mobile app craze. Despite taking into consideration that I am both a hardware and a software engineer, and rates outside of California were much lower ($45-$70/hour at the time). Which was one of the reasons I pushed hard to find my clients in the Bay area instead.

These days since I have more experience and business contacts I have diversified into more complex projects that have embedded components and pay me better since they belong to regulated industries. Even now I work with full-stack software programmers in AWS/GCP cloud apps, React/Vue frameworks, modern databases and connected middleware that make around $200/hour. For comparison, in the last years I have been involved in the development of a medical device where I did the hardware design (MCU/FPGA, signal acquisition), HDL/firmware programming (Verilog, RTOS, Linux, BLE), technical host tools (C++, Python, Qt) and was paid $180/hour, and lately a mobile robot project where I did the hardware architecture, integration and system control loops (MCUs), and prototyped the high level software application (RT-Linux, ROS, Nvidia Jetson) for $150/hour. An acquaintance in the valley that was working for a similar project but entirely in the ML/CV stack was billing $270/hour. That may be a bit extreme example since ML is hot today, but nevertheless.
The forced open bootloader proposal is the only right to repair law that makes any sense.
It's likely that most/all of that stablecoin was amassed by selling other crypto, which is zero sum. It's extremely unlikely that people took fiat currencies, and bought USDT directly from Tether, which is what they claim is happening.

No sane person would hold USDT over USD.
Gay marriage is a question of, among other things, mundane issues like taxation, upon which people can very reasonably disagree. Should Alan Turing have been able to put himself in a lower tax bracket by filing jointly with his 19-year-old roommate? It is a nuanced question; your answer might depend on what regime of divorce laws you're operating under (e.g. are you in a community property state or not).

If the service is acceptable, you tip ~20% (still okay to round down a few cents). If the service is bad, you don't tip 20%. Usually, if you complain, they will give you some part of your meal free or otherwise provide an adequate remedy, in which case you still tip 20%. Otherwise, it's okay to tip less. You can leave 10%. You can even leave 0%, but don't expect to come back. A sincere apology and attempt to remedy at least deserves some tip.

What? The fact that the fraud is successful for some non-zero amount of time is not evidence that it's not a fraud. It just evidence that it's a successful one, which is precisely what's being alleged. Enron, WorldCom, et al worked until they didn't.
Nice work!

You are suggesting private companies run their own immigration policy, which is insane.

You may think something is immoral, but we live in a nation with agreed upon processes for setting laws. You can't opt out of that and create your own private immigration law based on your own opinion.

You are free, however, to lobby and convince others to change the immigration laws. That is doing politics. You are free to even advocate for open borders if you want. It's a legitimate view. Reasonable people hold this view, although the same people understand you can't have a welfare state with porous borders. But it's not a view that most people agree with. Most prefer the generous welfare state and border control. Most people are perfectly fine with removing those who enter illegally back to their home countries.

If you think this is the embodiment of evil, then lobby to have the law changed, but don't try to enforce your own private immigration law. That's not doing "politics", that's throwing a tantrum. Politics involves working with the political system to convince a majority coalition to back your views. Throwing a tantrum is saying "ICE bad!! No business with ICE". Decide whether you want businesses to act like adults or like emotional children.
Tether is literally a short on bitcoin that is quick and cheap to transact in, it is keeping the price down rather than up. There's only 21 million bitcoins, but there's infinite tether. People really need to take a step back from mindlessly repeating things and think about what that actually means.

Go do a search of "tether site:news.ycombinator.com" to see how laughably wrong HN has been for the last 4 years on this subject. The adherents simply refuse to give up and many still identify with this "conspiracy"

I'm not sure we have enough eggs for the number of faces.

It's a widely known social norm in America. The same way you know to say 'thank you' or 'excuse me', Americans know to tip 20% for acceptable service.
Exactly. It’s 2 sides where one romanticizes “the other” and one romanticizes “mine”. You can argue morality all you want but it’s a social construct in either direction.
Ask HN: A digital picture frame that doesn't suck
Hey HN,

Looking to buy a digital picture frame as a gift, but nothing I am seeing instills confidence.

Would love to share directly to the frame via email, text etc, and avoid apps or memory card transfers.
How Microsoft made money from Android is quite interesting, and very ORACLE-like: Microsoft went around threatening OEM companies to pay up for a bag of patents it claimed Android infringed, but wouldn't publicly disclose which patents those were. Meaning OEMs couldn't create work-arounds. The mobile IP-wars were something.
If by “a few” you mean more than 5 then maybe. Free WiFi in all convenience stores, most train stations (almost all in bigger cities Tokyo, around half in bumfuck countryside where I live), many major public spots and department stores, expressway buses, and many cafes and restaurants all have free WiFi.

I was without a SIM card for several months recently and rarely had to go far finding connectivity.

Citation needed. Sometimes they can, but a large part of the time they are claiming things that they cannot hear if tested. They of course refuse scientific tests.
Do underwear have two pockets if the pocket is accessible from the inside and outside?

If exploitive or discriminatory practices exist, it's for our laws and courts to lay out the framework to address this and redress those impacted. If we have unaccountable agencies in government there should be mechanisms to dissolve them. I'm not saying this is what will happen, but the aim should be decentralizing power.

If there are failings in government, it's best to address the problems there. I'm not saying corporations won't expand its power over government if given the ability to do so, it's absolutely in its best interest to do so. The issue is they shouldn't be able to in the first place. A corporation is in essence an absolute dictatorship, and really shouldn't be given the power to exert an ideology over anything other than the purview of running the organization.
This has been posted a few times in the past, but I (re?)discovered it earlier today and have been having a lot of fun programming in it, so I figured I'd introduce it again.
My favorite C trick is not related to programming - but to debugging and disassembly. Unlike C++, there is no name mangling, so stack traces are a breeze to read, especially with -fno-inline-functions and -O0 or -O1. There is no implicit action at all (i.e. no exception handling or destructors) so there is a simple mapping between the assembly and source code.

My favorite "programming" trick only applies if I'm not sharing my code. I just forego header files entirely, and just #include the .c source files. Also, put `#pragma once` in all the .c files to avoid double-inclusion without the hassle of #if ... etc. This requires a bit more diligence since you can't have mutual recursion between source files.
I like American table service and can't stand European table service. I am a somewhat needy customer. I want another beer, different condiments, etc. and it's nice to not have to wait for them.
Exactly. Only those unaffected by a decision have the luxury of considering it entirely apolitical.
> In truth, the data dividend scheme hurts consumers, benefits companies, and frames privacy as a commodity rather than a right.

Privacy should be a right but it isn’t. At this moment privacy is very much a commodity or else we wouldn’t need articles like these.
> Most their costs are not cdn or video delivery. Its paying content creators.

if you're talking about youtube here (it's not clear from your context), youtube is paying content creators with 55% of revenue from an ad (since YT takes a 45% cut).

But YT only pays out when there's some $100 dollars of accumulated revenue for the content creator - hence there's also some arbitrage interest income that YT gets to earn 100%.
Couldn't you make the same arguments against eg Signal?
No, we like it because it gets us better service, at least the way we define better. Europeans are fine with less attentive waiters, but Americans are not. There's no sinister or complicated sociological reason beyond that.
My first modem was a Hayes-brand 300 baud modem. Atari 800 computer.

what makes you think you are special and able to resist manipulation?
The subset of techies you are talking about like to think that about themselves like that. They're as emotional and biased as the rest of us mortals, proof of that for example is characterizing the comment as irrational just because it doesn't "feel" rational to you, other comments talking about feminist re-educations camps or how climate change isn't that big of a deal.

I'm not trying to be antagonistic but one should be careful of thinking that they are inherently a more rational person.
If they would do what you say in your last paragraph, they would be cutting off new creators coming to the platform, which would be incredibly stupid since a lot of small time creators that make great content and wouldn't otherwise still make it big on YouTube.

Hiring people to do content instead couldn't replace that and hosting costs for small videos are not the biggest factor, I'm pretty sure.
Why would you not just get the original?
This isn't even new news: Tether changed their terms last year, and admitted/claimed to the NY Attorney General that they only have 74% cash last year.

Note that all of this is over a year before the Tether printer kicked into overdrive around April this year and started inflating from $4B to the current $18B+.
I agree with you. The keyboard/mouse has been a standard input combination for PCs since the 80s. Maybe it's time we added touch to the standard. Seems some additional input methods are likely well past due.
> Generally, it is considered preferable to find problems as early as possible.

Whole heartedly agree.

> If a program fails to compile or quickly crashes (because of a failed assertion), then I consider that better than having to unit test and fuzz test your code to find that particular problem.

This confuses me. My typical order would be:

fails to compile > unit test > quick crash at runtime > slow crash at runtime (fuzzing)

I am curious to understand why we differ there.
> Not exactly top of anyone sane's list of "problematic" charities.

The Salvation Army have a long history of homophobia. If you consider that anyone objecting to homophobia "insane" that say a lot about you, and none of it good.
Preferable in what way? Clearly the CIA has sinned and will likely continue to do so, but how can we evaluate an agency whose job by definition is either totally unseen (Espionage) or only reported on years after the fact (i.e. no one cares about the terrorist attacks that don't happen)
Thank you for saying this Ben! Be careful, Greenspan has a history of trying to burry criticism and threatening people who comment about him on the internet. He is probably looking up info about you right now.

On a personal level, optimization is a game and it's easy to get addicted to the game and forget about the goal.

There was a game called Vagrant Story on PSX where you can become invincible to all enemies. You can finish the game without this invincibility but it does look cool when no enemy can inflict any damage to you.

So my older brother went for the challenge. You can do this by getting an armor that makes small enemies damages smaller than the normal health recovery rate. Every time they hit you, it makes you stronger towards their element. This meant, my brother would turn on the psx, find a weak enemy, turn off the tv and let them inflict damage. He would let the psx on for days at a time. Put a little fan on the console and a glass of water on top (another optimization).

This also meant the rest of us couldn't use the PSX. Also, when my brother achieved his goal, he never played the game again.
The hygiene problem has multiple aspects. One issue is that the user's code can bind identifiers which the macro expansion expects to be predefined.

In a Lisp-1, we have to worry about this:

(let ((list ...))
(mac ...)) ;; expansion of mac wants to call (list ...)

Since the macro is not defining anything (its expansion is not introducing a binding for list), the ordinary gensym approach is not applicable.

THe problem persists into a Lisp-2 like Common Lisp, in this form:

(flet ((list (...) ....)) ;; binding in function namespace
(mac ...)) ;; wants to use (list ...)

Since local functions are rarer than local variables, and extra care can be taken in how hey are named, Lisp-2 mitigates the problem. Common Lisp goes a step further and makes it undefined behavior if code redefines a standard function (lexically or otherwise).

Hygienic macros solve this aspect of the issue as well. A hygienic (mac ...) can use (list ...) in its expansion. The hygiene mechanism ensures that this calls that list which is lexically visible at the macro definition (probably the global one in the library) even if the target site shadows list with its own definition.

Nobody's claiming that work is completely unrelated to religion or politics. That's just the inverse of the stupid claim that because work sometimes involves those things, we might as well do them as much as we want.
I just looked at coinbase's about page they have 35MM users now. Bitcoin is going through s-curve adoption like the internet. Fools on here look for conspiracy theories because they ignore demand increasing, for whatever reason.
He means that politics about ideas would sound like, "Should we spend more money on infrastructure vs. health care vs. lowering taxes," whereas politics about identity is "Black vs White vs. Gay vs Straight vs Native vs Immigrant, etc." There is no discussion to be had in the latter. When people are divided that way, politics is strictly negative sum.
> The imminent demise of tether has been predicted for many years now.

One thing that has stuck out at me from a white-collar crime reading spree is the amount of time that passes between something widely being seen as fraud by those who looked closely and when the walls actually start crumbling down. Enron, Madoff, Theranos, etc. all had people ringing the alarms long before the music stopped.
