Hey Peter! :) Thanks for asking! Some of the things we want to do over the next year include:

1) Expand to offer more subjects. Students ask us all the time for tutoring in English and history. Someday we hope to offer tutoring in every common high school course, including foreign languages and computer science too!

2) Improve the reliability of the site. We have something like 100x as many tutoring sessions happening every day as we did last year, and we need to make substantial changes to the platform to keep up with the usage.

3) Upskill our volunteers to improve the quality of tutoring offered on the site. We want to offer additional training courses on tutoring skills and implement a peer feedback system so volunteers can help each other improve.

4) Reach more students! We want to get the word out to as many students as possible about our free service. If anyone reading can make an intro to a high school or nonprofit who needs us, we'd greatly appreciate your help.

Ask HN: Google Ads brand protect campaign costs
Hi guys, the Google algo has included our brand name as a synonym into other competitors broad campaigns that target different keywords then our brand name. This is causing us to pay a high price for traffic we've already paid for via other campaigns (including Google). Any advice on how to deal with this nasty situation?

The time it takes light to propagate is not a determining factor in whether or not a particular animal reproduces (namely whether or not it survives to reproduce), so what evolutionary advantage could "faster light" confer?

In a more general sense, just because something exists doesn't mean we would evolve the ability to capitalize on it. Think of all of the abilities that would obviously be pretty advantageous which have evolved in species other than ours--that we didn't evolve a hyper-sensitive sense of smell is clearly not because of some deficiency in the universe because dogs and bears and others managed to evolve it..
You’re right that was an off topic note.

I guess what I’m getting at is that most current browsers support very nice JavaScript features anyway. And instead of adding yet another layer between our code and the browser—embrace the current generation of (at this point very robust) language features available.

And if that’s not good enough use something like TypeScript!

from https://www.nypl.org/blog/2011/06/13/great-slocum-disaster-j... :

The PS Slocum, built in 1891, was a paddle boat or sidewheel passenger ship. On June 15, 1904, the ship carried 1,358 passengers, plus crew.

Chartered by the St. Mark's Evangelical Lutheran Church for $350.00, the passengers came mostly from the German-American community of the Lower East Side.

Most of the passengers were women and children. As the ship made its way up the East River, good times turned bad very quickly. There have been varying accounts of how the fire started, but it spread rapidly within a half hour of leaving dock around 9 a.m. The panic was horrific among the passengers as they faced death by drowning or being burned alive on the ship.

... Only 321 passengers survived from a total of 1,358 passengers. The final death count totaled 1,021. The next largest death toll in the United States would come decades later with 2,974 dead from 9/11.
That doesn’t say it’s discrete. Only that there is a limit to precise measurement.

This will be downvoted, but I'm a bit skeptical of the "integrate Rust into big C projects" trend. It seems to me that it adds a lot of complexity: now there are two toolchains you must understand in order to contribute. There will invariably be subtle bugs at the interface between the two languages. Yes, memory and type-safety are wonderful, but they are not the be all and end all.
Yup, there is an upstream issue to improve this: https://github.com/golang/go/issues/44920

FWIW I'm planning to work on the problem from downstream as well by adding more docs here: https://github.com/felixge/go-profiler-notes . I haven't gotten to the mutex profile yet, but I've covered the block profile in great detail. It actually overlaps with the mutex profile for contention, but it tracks Lock() rather than Unlock() which is subtly different like you pointed out!
It's actually rocket-based memory management. Ba dum tss!
Did you spend some time reading these posts? I actually did and found them both interesting.

The first confirms that once DJT was removed off of large platforms like Twitter, he lost a lot of followers and digital support, proof that large scale networks have a strong positive feedback loop.

The second provides 2 videos that go into excruciating detail on why Elon Musk is a fake futurist, ruthless capitalist and overall a terrible person (Including working his factory workers at the TSLA factory through COVID forcefully, threatening their jobs and saying we will be at 0 cases by the end of April 2020). At the very least, you should dislike Elon for his anti-union, ruthlessly capitalistic approach to human labor and selfishness.

Is it really that complicated? Someone else on your ISP is almost definitely sending abusive traffic and it gets your ISP greylisted. Instead of blaming cloudflare you could instead get your ISP to proactively block / ban abusers.
The main complaint about it “tracking the friend” seems invalid. The tag isn’t “moving with him”, it’s sitting on a counter. That isn’t tracking, more accurately it’s basically a lost tag at that point.
A bit more than marginally more complicated, if you consider the cases of parsing partial or incorrect programs.

You want to be able to (somewhat) parse those so that you can syntax-colour, auto-complete, and mark errors in a code editor.

I think those are the major reasons modern languages don’t do such things the C way.

> Intel Corp to create a new lobbying group to press for government chip manufacturing subsidies.

Assholes. They don't need subsidies to produce chips competitively in America (since they already do) and Intel is one of the reasons the industry is so reliant on TSMC.

I'd much rather see this money go to founding a domestic TSMC competitor than to Intel. Or even to TSMC to have them build plants in North America.

Fabless design is here to stay, so it behooves the country (and world) to have enough designless fabricators to ensure sufficient manufacturing capacity.
That's not an incorrect way of thinking! If we need it to be effective for self-defense and existence, it probably needs to be protected as such.
Remind me not to drive a vehicle where you implemented the control systems.

This is a great example of a little knowledge being dangerous. There's a reason control systems are not implemented the same way as a browser DOM. There's a reason control systems are designed to avoid subtasks, conditional execution, interrupts (as much as possible) and complex data models. The reasons are pretty damn solid, IMO.

Conceptually, you can talk about the two domains as being somehow equivalent. That says nothing about the appropriate implementations.
Thank you I really appreciate your encouragement. I understand why you may want to be anonymous and especially for the example you gave. I don't think that's my blocker however I can certainly give it a try.

Organizing my thoughts and second guessing everything feels like the main blocker. If you look at my response to a sibling comment, it's worth pointing out that it took over two hours to write (while in work meetings with only a few times I needed to chime in). For some reason a response like this only took about 10 minutes. Perhaps because this is more of a thank you with a fact/comment. The other is much more of an idea/concept.
Same, though I've heard of expensing software or business books, and of course conferences.

All of the 'trustless' tumbling solutions I've seen tend to leave some evidence on the blockchain, it often only dilutes the certainty that a particular input maps to a particular output.

IMO, the only "surefire" way to launder bitcoin is traditional money laundering: send a trusted person dirty bitcoins and they send you back bitcoins from a clean legitimate source. Strong incentive for launderer to take the funds and run, so trust is unstable in this model.
Oh man! Domain knowledge is absolutely HUGE. I cannot even begin to tell you how much I've had to dive into literature on topics well outside of my domain to begin to understand how to use my outside perspective to come up with solutions.

Yes, a fossilized (not petrified) object has a density similar to stone, typically around 2.7 kg/m^3. Bones, like most living tissues, have a density close to 1. So to a first approximation, this would have weighed 1,000 lbs when alive, comparable to the head of a modern elephant.
"Quantum speed limit" as is usually used in the field has little to nothing to do with the speed of light.

With more detailed purchase history available it seems like price indexes should switch to purely volume weighted adjusted price indexes. The quantiles of purchase history would show a much more accurate history of consumer behavior over time; A rise in the ~10th percentile price of goods by volume is a pretty clear indication of fundamental inflation whereas median or higher percentiles may only reflect fads, substituted goods, or improvements in quality, for example.

Maybe such an index already exists? It looks like CPI is switching to this kind of price adjustment for some categories but it seems like the data is readily available for basically all consumer goods; Are stores reluctant to share the volume and price of goods at the individual UPC level?
I'm ok with subsidies if they open up their designs.

Important to keep in mind that if a meteor hits Earth, Mars will still be more hostile to life.

The Earth has lost many species of animals due to planet-scale events, including at least one meteor, and still life continues. Mars has been dead and naked to solar radiation for the entire duration of all known life on Earth.

People love to romanticize things like this, but they're far removed from reality.

I very much want people to explore Mars, but permanent Mars colonies are incredibly unlikely within our, or our children's, lifetimes. We may very well grow up and die during a period of time where no human sets foot on another body outside of Earth.

The problems on Earth don't make it more appealing to colonize Mars, they make it harder to justify going there at all.

Apple's iOS platform matches both these conditions.
As a user, I'd love the option to decide whether I want to help in this system or not. Similar to how I can opt-in to sharing analytics with Apple.

I just might help out. But the idea that by owning an iPhone I'm automatically opted into this and I can't (temporarily) disable it is concerning. Especially since the feature to alert users of the possible privacy invasion outlined here, seems to not yet be working as advertised.

It's unclear to me if the "Participate in 'Find My Network'" option is what I'm talking about. But I also don't remember being asked about this at any point.
Apple and the likes need more chips to make more money and they have big coffers. Instead of public subsidizing those fat cats let them take care of that pesky money issue. They can afford it.

Swift Actors need some improvement.

For example, how could Swift Actors implement the following:

TrainController ≡
moving := False // train is initially not moving
isOpen := False // door is initially closed

open ↦ moving ?? // Received request to open door, there are two cases for moving:
False ↠ // Case moving=False, then
isOpen := True; // then set isOpen to True and then
DoorController.open // send door an open request in hole of the region
True ↠ Throw TrainMoving[] // Case moving=True, then throw TrainMoving

close ↦ Hole DoorController.close ; // Received request to close door, so send door a close request
// in a hole of the region and after door reports that it is closed,
isOpen := False // set isOpen to False

move ↦ isOpen ?? // Received request to move train, there are two cases for isOpen:
False ↠ // Case isOpen=False, then
moving := True; // set moving to True and then
EngineController.move // send engine a move request in a hole of the region
True ↠ Throw DoorOpen[ ] // Case isOpen=True, then throw DoorOpen

stop ↦ Hole EngineController.stop ; // Received request to stop train, so send engine a stop
// request in a hole of the region and after engine reports that it is stopped,
moving := False // set moving to False

I would say that a good data scientist can quickly estimate where their time is best spent, either accepting what someone else has told them as-is or investigating themselves from the ground up. There's always more to investigate so using your time efficiently is one of the most important DS skills. Like solving a multi-armed bandit problem.
My exact reaction as well. Or how about all that money used for stock buy backs over the last decade? Intel especially. It's been mismanaged and now it's putting its hand out for government money while having spent billions on stock buy backs. No more but of course it'll happen because the politics of it. Socialism for the rich and corporations, capitalism for the rest of us.
The flags were correct. The first link was unsubstantive, and you can tell from the comments why people were flagging it: https://news.ycombinator.com/item?id=27112503. The second was flamebait on the biggest flamewar topic in months. By the time it was posted HN had had a massive number of threads about it (see https://news.ycombinator.com/item?id=26713650). It's easy to see why users would consider yet another such post off-topic.

You don't have to resort to "beliefs" to explain those cases. You may be falling prey to the bias where the bad (what you don't like) stands out more than the good (what you like), leading to false feelings of generality.

Wealthiest entities on Earth lobbies government for handouts.

I'm not even being snarky, this is just a lobby group trying to socialize costs to avoid spending their own money. Explicitly: “Government should refrain from intervening as industry works to correct the current supply-demand imbalance causing the shortage,”. The industry is not stripped for cash at all, so if the government is not expected to steer, why should it put up the people's money?

Back in the early 2000s when hand-held GPS receivers/loggers started becoming relatively cheap, some white-hat hackers tried sending them through the mail to see how the postal system worked and produced several articles and presentations on the results.

It turned out the USPS took a very dim view of this kind of thing.

correct, but that does not make coverage calculations incorrect since it is based on the snooped FQDNs.
I wish smart folks would do better in terms of pointing out these generalized lessons as though they're universal.

The reality is that party rounds, like any form of funding, have positives and negatives, and whether they're good depends on who's funding and who's being funded.

If you're starting a company like Cameo, having a party round of athletes/actors/celebrities is likely more valuable than a regular round of traditional VCs.

> Libertarians who support UBI think of it as replacing the other stuff. This is a wildly unpopular opinion on the left, who want everything else (welfare, college, childcare, healthcare, retirement) and UBI.

Really? I've never heard this before, and I'm pretty far to the left. Replacing all those other things with UBI sounds like a no-brainer. Why administer N different welfare systems when you can administer one? But I think the larger issue is that "the left" does not at all agree that UBI is a good thing, regardless of implementation.

I think objections to replacing (specifically) Social Security are political in nature, not policy-based. In that anyone (left or right) proposing to eliminate Social Security -- even if it's replaced by something better and more comprehensive -- would get voted out next election cycle. It's a very touchy subject, I think.

One exception I will make is healthcare, though: I don't think we should keep our current healthcare system and just expect that, instead of getting insurance through their employers, everyone is expected to pay for it individually with their UBI check. We need a major overhaul that gets rid of the private insurance system (or at least makes it the "not really needed, but rich people can get it if they want" type of thing) and removes all of the unnecessary graft in medical billing. (I get that this is also a touchy subject, so I certainly accept that M4A or whatever is not the One True System and that there are other options that might work just as well. But our current system is absolute garbage.)
