Yeah, it's a little tone-deaf.

I understand it's meant to be tongue-in-cheek and all that. But if, for example, they used a swastika, even if they were using it in the context one of the dozens of cultures for whom it's a normal symbol, it would still be tone deaf.

A lot of people here are saying it's just a symbol, etc... But if it was a Christian cross, I bet a lot of HN readers would flinch with "I'm not supporting some fundy company!"
If your password is derived from a four word phrase (per the XKCD formula, which isn’t the only one), potentially all of the individual words could be inoffensive in isolation. There’s no obvious way to operationalize the human intuition of offense in a way that restricts the search space if you’re smart about it.
Having ridden existing rideshares, there is precious little quality assurance a simple voting system could not solve, as it has for uber/lyft.
I hope this kills the company. I think that working for Palantir is going to be the same as working for Philip Morris.
Seems like a weird reaction to hearing that a man has been indicted, but okay.
It's also worth mentioning that the Raptor engine is meant to use fuel made in ISRU systems on Mars. Most (nearly all?) components of Methane fuel for the Raptor can be extracted from the Martian soil, rocks, atmosphere, etc. A primary design consideration for Raptor was that it should enable Mars missions, and Mars missions are nearly impossible to do without manufacturing your fuel on location, so Raptor is ISRU-first with a Methane fuel.

Everything SpaceX does is moving towards a goal of enabling a colony of 1M+ people on Mars as soon as possible. A lot of people are confused by SpaceX decisions, but if you view it through the lens of Mars colonization, then it all usually makes more sense.

I think Raptor might be the first Methane-based rocket engine as well.
It's not about whether the government dislikes a company, but whether it believes the company is acting in bad faith.
No other rideshare inspects cars, this is a problem with uber also.
After reading almost all comments, all of this make me think that your positions on the debate are based on psychological characters. Some people are idealists: as Javascript is in some state, but could have been a lot better if history had been different, they CAN'T be happy, they won't. They need to find THE right tool before working with it (I'm an idealist). Then, you have other kind of people which are more adaptative: they tend to accept the situation "as is", and try to withdraw the maximum of benefits of the language. It's easier for them do deal with the issues because they accepted the situation initially. BTW, I think those people are more happy in their daily life. And last, the negationists: they refuse to accept the truth. Those people rely on wrong things (like trends) to evaluate the quality of the language. For them, if JS is used so much, it MUST be good, even if they're not sure why. They believe world auto-regulate itself with natural selection (like ultraliberal people). Plus, if they start to use it, they don't want to hear it's bad because it would question their choice, and by extension, their intelligence.
According to https://en.wikipedia.org/wiki/VP9, Sisvel said it will demand a licensing fee for VP9 from device makers.

It may make more sense to adopt AV1, which is truly license and royalty free, but the encoding and decoding speeds are slower or just on par with other standards. Its only real advantage appears to be significant bitrate savings, so seemingly only streaming video providers would benefit.
Ironic given where most of SV's money and tech knowledge came from.
But you are no safer than hitchhiking. Its an illusion.
The end game for Starhopper is the Super Heavy/Starship combo, which (if it all works out as planned) will be able to lift around 100 tons to low Earth orbit and be fully reusable with no refurbishment needed between flights.
Not an annoying question whatsoever.

Dense urban environments are challenging. The error distribution is more complex there, its hard to definitively say. The numbers I'm quoting is for open sky environments where you have plenty of satellites and little multipath.

For the average end-user, these are $500 GPS units (this is the one I work on: https://www.swiftnav.com/piksi-multi). The technology is already moving down the supply chain to ~$10 GNSS units from Broadcom and ST (we're doing this: https://www.swiftnav.com/news/swift-%E2%80%8B%E2%80%8Bnaviga...)

The issue with phones is mainly an antenna issue. Your phone antenna is tiny and squeezed in alongside half a dozen other antennas and radios. This degrades the GNSS signal quality a lot. A stopgap here is external GNSS antennas for your phone: you might plug your phone into your car and get lane-accuracy turn-by-turn directions, but it's unclear when we'll have high accuracy GNSS inside phones, but most major phonemakers are indeed working on this.
Perhaps a better investment would be to buy a road bike for $2,000. Spend $245 on a trainer and gear. Finally, get the subscription to the classes, and now you have both Peleton classes and a road bike.
This a hundred times. I've had people suggest that I could help my sleep apnoea by losing weight or quitting drinking on the internet after I've mentioned it.

Never mind when I was first diagnosed I was actually underweight because the chronic lack of sleep had completely removed my appetite and that I only drink a couple of times a year.

It also assumes that this advice isn't something my doctor wouldn't have given me if it were appropriate
I’m a mega bear on this. It’s Juicero 2.0

This is just creating a fleet of useless metal that will have software vulnerabilities up the wazoo in a decades time.
I've heard of 80000 hours before but if I'm not mistaken it's more for people who don't _have_ to work to earn money.

A while ago one of their career advice blog posts gained traction and it read absolutely as advice for someone who doesn't have to worry about money at all. One of the pieces of advice was something like "don't make long term plans" and there was no advice at all about compensation.

E:

Found the blog post: https://80000hours.org/2019/04/career-advice-i-wish-id-been-...

It includes advice such as "Don’t focus too much on long-term plans" and "Crowdsource your career decisions".
It's good short term anyway. Whether it bites them in the end is basically a question of whether they make their brand untrustworthy. They seem to be doing so.
Wouldn’t it make more sense to figure out a lunar-agriculture schema rather than replicate what we have done on earth?
In similar systems, the position is generally tracked with the combination of interial sensors (accelerometer / gyro / angular rate sensors) and external references like GPS and star trackers.

Inertial sensors are able to provide high frequency data on change in position and orientation. Higher frequency means the software can make much more rapid decisions to steer the rocket, on the order of 1000 a second or so, much more often than can be achieved with GPS.

The fact that inertial sensors don't rely on external signals (like GPS does) means that there is some degree of robustness- for instance, if there is a temporary disruption in GPS signal reception, the rocket will still have some idea of its position.

Over time, integration and measurement error accumulate from the inertial sensors. (Remember that they generally measure changes in position / orientation, not absolute position or orientation). For this reason, it is usually necessary to use external position and orientation references to correct the error that accumulates over time. GPS is used for this, and in some applications, star trackers can be used as an absolute orientation reference.

On the algorithm side, a Kalman filter combines measurements from all of the position and orientation sensors to generate a prediction of the current position / orientation / velocity / acceleration etc.

I find copy as Fetch easier to work off of (copies as prettified JSON instead of a single line CLI string) + it comes with the added bonus of being able to do any quick tinkering in the same dev tools window.

2115: A 100-Year Review of Ecomodernism
That's not obviously true by itself without some underlying unspoken premises we probably do not share.

I reject mercantilistic views of economy. They belong in the 1600s where they died.
Interesting that they're worried a prevailing attitude amongst the laborers in tech that we shouldn't be engaging in things Palantir profits off of (like migrant concentration camps) might cause them to attack the industry itself.
Setting it up with HAProxy is a bit tricky but possible as well!
You're judging RSS adoption by the number of people who search google for "rss feed"? This seems incredibly wrong. What am I missing?

The politics of tax reform are poison as well. There will always be winners & losers with any change, so opponents of change will always be able to say, "this proposals raises taxes on ___." Fill in the blank with whatever polls the best.

Of course politics has zero room for nuance, so we shouldn't hope that the tax code will become simpler in the foreseeable future.
I wouldn't say it's an impossible problem. It's fairly simple, in my mind.

If someone tries to send me a message on Signal it should go into purgatory. On my end, I should be able to see who is trying to send me the message (yes, including their phone number, given that is how Signal has decided to uniquely identify users) and I should be able to see what their public key is. Then I should be able to either accept that message, which would essentially make my presence on Signal known to the other party, or choose to first verify that the public key matches that of the other party via the existing "in-person" verification method.

Alternatively, I can leave the message in purgatory where a message from someone I don't trust belongs and eventually times out. Not only do I never see the contents of the message, but the sender of the message will also never know if I am on Signal.
I'm surprised by this move seeing as it seemed to be fairly heavily marketed, but the deprecation timeline seems generous.
Selfhosted TinyTinyRSS
Yup, leave that to Wall Street, defense contractors and oil companies. Can't have these engineers messing with the status quo.
As others have mentioned, there is a fear that if RSS users aren't viewing ads and RSS users keep decreasing in number, eventually, content producers will stop supporting it.
I think it's nice that someone is working for ethical hardware.

Is it possible to run more ethical software that doesn't track you? (not google-based android)
I agree definitely mostly dead and slowly dying off in exponential decay. Used to like my summaries but over time sites dropped it or only updated once in a blue moon. Mostly moved on to just bookmarking my favorite sites and making due.
What I meant was it's easier to eat less calories if you restrict the amount of time you're allowing yourself to eat not anything about absorption being different due to the compressed time frame.
In addition, if you're shipping smaller heavy items, you can get free shipping supplies like padded envelope and boxes for flat rate shipping which can be a better rate in some cases.
Yeah, seriously. Are email addresses even regular to the extent that a regex would work 100% of the time?
The main assumption everyone makes is that Tesla/electric cars will be more reliable compared to ice cars as they have fewer moving parts. Electric cars haven't been around long enough yet for long term evaluation.
Where to Find the Fastest Airport Wi-Fi in the U.S. and Canada in 2019
You buy a SIM card from a wireless provider, register your service, and you're connected to that provider's network. Depending on which country you live in, you may be asked to provide evidence of your identity to varying degrees.

For example, to set up my service in Australia, I bought a SIM card in a little packet at a corner store for A$40. The SIM card was from a specific wireless provider (Telstra, in this instance), but it was sitting side-by-side with SIM cards from other providers in the store. It came "pre-loaded" with 35GB of data to use on their network, plus unlimited SMS and voice calling, which was described on the packaging. When I put the SIM in the device I was prompted to go to a website to register my service, where I input a code from the SIM card packet to link the SIM itself. I was asked to provide my driver license number or passport number. I was then able to choose between three pre-selected phone numbers that were displayed on the screen. Click Finish, and my cellular service started working on my phone. Every month I have the option to renew my plan under the same terms, or choose a plan with different terms (more or less GB of data, for instance), or throw the SIM card away and switch to a different wireless provider.
This is why the real world runs on reasonable people, backed up with lawyers and judges to interpret laws and the mis-use of them either through badly written laws or unexpected consequences of reasonable intent - and why even people strongly publicly opposed to that end up reinventing it and forking Etherium when someone read "the code that is the law" more carefully than the people who wrote it.

A judge will (sometimes) look at a nov el abuse of the details of a law as its written, and make a determination based on the clear intent of the lawmakers even if it's not specifically covered by the written embodiment of thew law.

Anyone who thinks that's bad idea needs to get out more. (I'm not saying it always works out "best", but not having the ability for someone to say "Hang on, that's not the _intent_ of this tax rebate. You can no longer abuse it this way." is critically important, for a species that cannot write bug-free code in the super-restricted space of computer languages, never mind in the vastly more complex and error-prone space of human languages for laws and legal contracts.

I can’t answer all the questions but I can talk about RTK techniques. I recently used two $75 GPS receivers and two raspberry pis to create an RTK GPS system (real time kinematics). With RTK you have one receiver that is fixed - it does not move. The other receiver is on the thing whose position you want to measure, and the two devices are connected through the network. Because the system knows the fixed station is not moving, any drift in measurement represents the real time error of the current satellite constellation. The moving unit subtracts that error from its own measurements to get very precise figures for its position. In the system I built, it seems to have centimeter level repeatability. That is, if I am looking at the read out in real time and I stop moving the receiver, the drift in the measurement is a couple of centimeters. If I move it 20 centimeters that is pretty closely reflected in the read outs. Currently I don’t know the absolute accuracy of my system but the relative accuracy is very high!
This is just politics masquarading as tech issues. Take your concern trolling elsewhere.
Ask HN: Beginner Programmer: Haskell Book or SICP?
The extent of my programming involves MIT's Scratch, AppInventor, calculator games for TI83, some limited Javascript & Python from Codecademy, some HTML/CSS, and some CLI experience.

I'd like to learn programming & computer science, so I'm taking an intro programming class (CS 161), which uses Python. However, I want to do some learning before the class starts, and I bought the Haskell Book [1] about 2 years ago. I've completed the first 5 chapters. People highly recommend SICP [2], so I'm wondering if I should do them concurrently, or just pick one. I'd like to continue with Haskell, but if I'd be better off with SICP, especially for the Python class, then I don't mind putting Haskell on hold.

From reading HN over the years, I've gathered that many people believe functional languages better suited to learning CS. So I'm apprehensive about diving into Python and not grounding myself or exposing myself to functional disciplines.

Thank you for any advice

"Room temperature" already makes this concession as it means above 0C. In the context of superconductivity I would assume "room pressure" to fairly encompass pressures higher than 1 atm, though I don't know if there's a practical cut-off as there is for temperature.
Where is information stored securely? On a private server not accessible from outside and protected by law or on foreign publicly accessible servers not protected by local laws?
The headline is incorrect. "Large tech platforms shouldn't dictate policy winners and losers" is more accurate.

I think his view is well reasoned and while you can disagree ideologically, I would like to hear the reason.

I'm eager to hear what you think I'm incorrect about.

Clearly the baker in the story, who wins, lives in what most people would call an ethnic enclave (if such a thing exists). There's an expectation on the right that it's easy to identify when an immigrant is "one of the good ones" but that identification tends to be done at a comfortable distance, that doesn't tell people on the right anything about the people they're actually judging. As a result, the default view is that immigrants often aren't integrating, and that's bad. That's not a stormfront view - that's a very mainstream right wing view. The truth is that immigrants often desperately want to integrate, and that culture, and even celebrating and maintaining one's culture, is not incompatible with integration. People can and do have both. St Patrick's day doesn't stop people from celebrating the 4th of July. The difference between integrating and not integrating, from the signals given off by the right, is approximately 50-60 years. Suddenly, the Irish in NYC have all mysteriously integrated for some reason, when back in the 1850s they weren't integrated. So strange how that works, right?
I'm curious, what is the alternative to illegal migrant jails?
That link implies RDMA SMBd is not available on regular Windows 10 Pro. I wonder if that’s really true.
A minor addendum, you should feed your Kalman filter the gimbal and thrust of the rocket too, it'll happily chow down and combine that with everything else to further improve its estimate.
I wonder if there might be a way to utilize the same effect that creates a Prince Rupert's drop to create that sort of stress in a superconductor. Sure, it would be fragile but it would also be stable without external forces applied. The stresses contained within the surface layer of the bulbous end reach as high as 700mpa which might be increased by using better materials and colder "shock" processes.
From their unordered list of items on the technical roadmap they include the following.

- Make it safer for passengers and drivers

- Add drivers/passengers rating

- Make it easier to use and safer for moms/dads and children

- Make it easier to use for people with disabilities

Who knows if they'll do those things. They seem to be aware of some of the challenges. In regards to #2 they are probably planning on relying on donations in the short term.
This statement is accurate based on my interactions with general users.

It's not just "junk news" though. People can and have been caught out by things like Microsoft tech support scams, fake virus alarms and prominently displayed on the Microsoft news feed. I've reported to Microsoft before direct links to ransomware advertised on their news feed.

The Future of DigitalOcean Inc – Private Equity vs. IPO
Yeah, you know, I'm not really convinced myself to be honest. Obviously you want to take advantage of comparative advantage, etc. but is a more prosperous city one which has a less unequal income or wealth or does optimizing for top-line wealth just create everything else along the way? I don't really know.

I'm pretty comfortable abandoning the view. It wasn't built on a strong basis.
What is the Blub Paradox in computer programming
Dr. Gerald Pollack has studied the "fourth phase" of water, which are sheets of H1O1. Water in this phase is electrically negative and forms the surface of bubbles/droplets, vesticules in cells, clouds, plasma in blood, & drives movement of water in plants. This book explains a number of phenomena with models backed by experiment.
