At 865 nm, laser eye damage is due to the laser being focused by your eyeball into a small spot on your retina. This is in contrast to other wavelengths, like 1550 nm, which do not get focused, but can instead damage the surface or your eyeball at much higher powers.

However, when there are many 865 nm lidars around, each one gets focused to a different spot in your retina, so it is not any more likely to cause damage than a single lidar. Thanks to the low power of the Ouster lidar, it is Class 1 eye-safe at any distance.

If there were a hundred high-power 1550 nm lidars all pointed at the surface of your eyeball, however, I wonder if it would be more likely to cause damage?

The point is, meat is freaking delicious. You can't deny it. The smell of bbq will get most people drooling.

Some people, you will never convince to eat veggies instead, especially if they taste way worse than the meat they love. But if you have an alternative that tastes just as good, if not better, than meat, and is cheaper (with economies of scale), they would be more willing to go with the veggie option.
Or they could, you know, fix their review system.
There is both an overt development bureaucracy of Bitcoin and a shadow group. The overt effort is managed by MIT https://dci.mit.edu/ MIT developers have merge access to the Bitcoin official repo, which is truly the real power.

The shadow is who influences these people, and why. It really isn't conspiratorial - it's the long tail of influencers, media, meet-up groups, conventions, exchanges, and people who have a stake in Bitcoin.

Anytime there is a major disagreement, there is a fork. This is how numerous forks were created, the biggest of which are Bitcoin Cash, which later itself forked into Bitcoin Cash SV. A fork is just a group of developers who disagree with the official Bitcoin bureaucracy at MIT. If these dissenters have enough support then the new coin has value.

Bitcoin is old and stable, and through its age and stability it has gained trust. Major changes to Bitcoin simply won't happen anymore. The Lightning Network required very minor changes to the core protocol, and using Bitcoin's constrained tooling developers have (heroically!) engineered a scaling mechanism. It is not yet perfect nor easy to use, but over time the client services around it will improve.

The extreme wariness of core Bitcoin developers ensures that trust is maintained in the protocol. A major disaster in Bitcoin would be very bad for the whole industry.

If you don't like Bitcoin, just create your own coin, or fork from Bitcoin! Such is how so many new coins are made.
FANG recruiters will even give and encourage these study aids to candidates before their interview.
Uhh... I worked in an adjacent industry for a while and multiple interactions with big players and small players left me the distinct impression that it was the other way around. Little players just kept doing what they did the year before because it "worked," no matter how sub-optimal, no matter how long-term detrimental, while big players hired agricultural scientists that actually knew how to measure, optimize, and spend money on costly upkeep with an expected long-term payoff.
The there's too much to moderate argument for internet companies sounds like the too big to fail argument for banks.
There's an oddball NYC tradition of (not strictly observant) Jews going out for Chinese food on Christmas because those were the only restaurants that were open. The Chinese restarauteurs are appreciative, but sometimes mystified...
I agree on a lot of this.

The sceptical and possibly modernly-ignorant part of me is stuck in 1997 clicking "Yes I Am Over 18". I must be missing 20 years of Internet Technology Advancement somewhere and am open to edification.
Not about the gaming/IT industry but "Shoe Dog: A Memoir by the Creator of Nike" is another incredibly motivating founding story
The mining is also pretty centralised these days:

And the Chinese company that produces the most asic miners (Bitmain)... also runs a mining pool. Gambling. In a Casino. Shocking.
> By some estimates human beings perceive two events as instantaneous at around 100ms.

Would be fun to design a realtime audio app using that supposition.

Also, a question to troll fans of the phrase "Gell-Mann amnesia effect": how flippantly should I now reject the other paragraphs that are outside of my expertise?
This type of play usually used for short term buying and selling. I.e options.
Really enjoyed "The Idea Factory". I'm currently reading "Sandworm" - more cybersecurity related, but it's really good so far.
Performing the instruction is a 90% solution. You do a 90% solution for the CPU, a 90% solution for the PPU, a 90% solution for the sound, etc, and implement the dozen or so most common backswitching chips. Then 75% of games are playable and 40% of all games are bug free. Maybe less.

Then you start working on those last 10%s, which includes cycle accurate emulation. As it happens, there's a lot of work with goes into the final 10% of the various NES subsystems. Far, far more work than the first 90%.

As for what percentage of games need cycle accurate 6502 emulation I couldn't tell you.

Not that I want to apologize for poor performance, but I remember feeling let down by that review because some obvious differences between the platforms were not highlighted that should feed into the conclusions, not the least of which was the drastically different memory used between the two platforms.

The article was billed as "let's see the difference between AMD and Intel" but there were significant platform differences that made it not quite apples-to-apples.
Holders of Bitcoin also have a say in what forks are viable.
If I didn't in fact advertise on telephone poles, then I would say that wasn't my sign.

If I didn't advertise on telephone poles but somebody else was trying to frame me, and then I proceeded to act as though those signs were my own, then why would I not deserve punishment? If those signs advertised my business and I neglected to disown the signs because I was greedy, I think I'd deserve to be fined by the city. If I admitted on a recorded telephone call with a detective that the signs were mine, even if they weren't, then I've screwed myself with my own greed, which is fitting and just.
I do not think that is true. The winning chain will be the one where most people accept the coins from. Miner will only follow.
they could do it but they don't want to because they don't have to.
Even though developer slowed down, he did not abandon the project and continue to develop it in spite of not making it open source.

This requires tenacity and persistence, which is at display in this project.

I moved away from this programs since MS Windows is not important for my company or my customers. My teams and I on personal level didn't touch any MS windows OS or machine for over 6 years now. No one in my team even wants to touch anything with Microsoft OS, they prefer either FreeBSD, Linux or Mac OSX (mostly used as unix with a good peripheral device support). In a rare case if some customer wants some support on windows the first thing to do is to install WSL with Ubuntu and then it becomes useable.
Two of those three startups are clear losers. Not surprising.
It pains me to see another Coding Interview preparation tool. It's such a sad situation in the current industry.

Students learn to game the system to get a high paying job. Students who care about what they are working on will painstakingly try to perfect their projects. They don't have time to game the system and therefore have a hard time getting a coveted job.

Companies want to hire "the best" so they usually hire someone who can ace the company's interview. People who can ace the company's interview are usually those who studied for it.

I recently took over a codebase from an ex-employee who went to Google. People were happy for him but I am so indignant. His code caused me hell. One production bug after another led me to eventually throw out all of his code. His code was written by somebody who did not care and his tests were useless. I'm pretty sure during his time at our company he was focused on leetcoding so he could get somewhere better. I wanted to reach out to him on LinkedIn to give him a piece of my mind hoping it may make him a more responsible engineer but I decided against it. I focused on fixing the features for the users because it was the right thing to do.

I want to work with people who care about the product they are working on. People who care about building great products are not solving coding interview problems.
A lot of processed food is bad for you, but that doesn't mean that processed food is inherently bad for you.

Computer history is one of my favorite topics, so I've read a lot over the years. Here's my list:

>> Classic computer history:

- "Hackers: Heroes of the Computer Revolution", Steven Levy

- "The Innovators", Walter Isaacson

- "Valley of Genius: The Uncensored History of Silicon Valley", Adam Fisher [innovative format, tons of interesting tidbits after you get used to the style. Read only after the other two above]

- "The New New Thing: A Silicon Valley Story", Michael Lewis

- "The Second Coming of Steve Jobs", Alan Deutschman

- "Revolution in The Valley: The Insanely Great Story of How the Mac Was Made", Andy Hertzfeld

- "Masters of Doom", David Kushner

- "Idea Man", Paul Allen

- "Where Wizards Stay Up Late", Katie Hafner

>> Entertaining stories, but less historical value:

- "Ghost in the Wires", Kevin Mitnick

- "Chaos Monkeys: Obscene Fortune and Random Failure in Silicon Valley", Antonio Garcia Martinez

- "Hatching Twitter: A True Story of Money, Power, Friendship, and Betrayal", Nick Bilton

>> On my to-read queue:

- "How the Internet Happened", Brian McCullough [just started; very promising]

- "Troublemakers: Silicon Valley's Coming of Age", Leslie Berlin

- "Code Girls: The Untold Story of the American Women Code Breakers of WWII", Liza Mundy

- "Fire in the Valley: The Making of The Personal Computer", Paul Freiberger / Michael Swaine

>> Others worth mentioning (but just read a few chapters):

- "The Supermen: The Story of Seymour Cray", Charles Murray [about Cray Computers]

- "Racing the Beam" [about Atari]

- "Commodore: A Company on the Edge" [about Commodore]

>> Bonus:

- "Art of Atari", Tim Lapetino [great as a coffee table book, particularly if you grew up in the 80's :) ]
I'd just like to see high quality 1440 panel laptops come in vogue. Why do I need a 4K 13" laptop when I can't discern the difference between 1440 at regular sitting distance? Wasted pixels and wasted battery. Also, it seems like the 4K panels are the only ones with wide color gamut and proper color accuracy.
if you don't like youtube for your kids, ban it and give them access to netflix and the like.

somehow youtube became the parent that oversees what content your kids get. this to me is a dereliction of your parenting requirements.
Quite possibly, but they are also quite correct - you cannot scale a full mesh network to anything remotely resembling the capacity required, it has to be some kind of sharded, p2p topology.

At which point, and the irony here is quite profound I agree, you are starting to look at something that looks a lot like the existing banking system.
I have a category on my bookshelf of semi humourous memoirs of engineering projects.

The two classics are:

Surely You're Joking Mr. Feynman, about the Manhattan project and other places he ended up.

And Tracy Kidder's The Soul of a New Machine, about the engineering effort behind the Data General Nova. This one literally has a Pulitzer.

I also enjoyed The Race for a New Game Machine, but not as much as the above books.
Not being able to review all the content is entirely a problem for Google to solve. Maybe they should stop optimizing for growth and put up some hurdles to who can upload content?

This sentiment is so shocking that I had to say something.

Please no. Let's not encourage a world where people are even less free to share their ideas.

I get where you're coming from, but "Think of the children!" has been used to justify so many evils throughout history. It's an emotional appeal that should be resisted.

Putting up barriers would also be the first step towards losing dominance. But in the short term, it would suck not being able to share a video without waiting a long time or being approved.
here's another crazy idea:
if you're just going to hand over your kids to youtube then maybe your parenting priorities are missing.
Excerpt from the article: "Jason: I saw one troll spoofing your name and picture post an extremely nasty, long-winded comment on Goodreads, discussing intimate details of your family life and making it sound like you want to kill yourself. None of this could be considered a review of your book by any conceivable means, yet Goodreads still hasn't removed it. What's going on here?"

I'm really curious how anybody thinks this isn't harassment.
Unfortunately FMCW lidar is sweeping the lasers across the same band. You don’t need the exact frequency just a beat frequency that’s within your detection Bw.

Also balanced detectors have something called common mode rejection. This is not infinite. In high volume applications it’s difficult for this to be >25dB but you can buy some devices >35dB.

Given that Lidar dynamic range is ~100dB you will definitely see the DC. I’ve not thought about this too much but it seems like an issue for the AGC as your demodulator won’t be bothered by it.
The best way to realize how malleable you are is to imagine what beliefs you would hold if a baby of your identical DNA was born 5000 years ago to a royal family. You’d probably be completely down with slavery, pillaging, monarchy, etc.
Now zoom back one level. Most of the jobs (not all!) are doing something pointless like increasing advertising revenue.
I've had the Beyond Sausage at Dunkin Donuts. It was acceptable, but actually more spiced than you normally ever get from a sausage patty — probably to cover up for other deficiencies.
I believe that the 737 Max disaster was directly caused by the idea that management is a valuable skill on its own, that management is somehow separable from the domain-specific knowledge required in order to make an honest buck.

I don't think that's a fundamentally different idea, though. I think that's exactly the idea that drives any leveraged buyout or any cost cutting measure - that "good management" can make up for jettisoning whatever previously enabled a company or division to succeed.
Written for those who are hiring and good advice to freelancers too.
Seconding this recommendation, great book.

The Cuckoo’s Egg is not quite similar to Masters of Doom, Where Wizards Stay Up Late, or Hackers, but it’s an extremely good book about tracking hackers and Berkeley Unix (BSD). It’s motivating in a similar way though :)
“ Something like automatic per-issue bounties.” I physically shuttered at that thought. I get the intent, but having labored qualified and paid for in that way is sure to lead to a terrible issue system gamed by those “in the know” to exploit the rest.
So it's meeting someone via a mutual connection?
Good. Science is meant to be a honest search for facts: data, knowledge and wisdom. Being wrong is a feature. "I don't know" is an acceptable starting point with no shame attached. Being certain means a mountain of data to back it up. Being allowed to be wrong is a requirement. Anyone saying a scientist can't ever be wrong is likely placing oddball limits on progress that will only damage and limit the future[1]. How can you experiment if you can never be wrong?

It would be good if people knew about the mountain-of-data aspect of science. Even with that mountain, subtleties creep in and plenty of surprises still remain.

Even something like water probably has properties we are clueless about. Interesting aspects that might redefine science itself and create entirely new approaches to medicine or manufacture or whatever. Maybe if you change temperature and pressure enough in the right way you end up with exotic metallic / bonding properties. Or some new water-based ion structure having other properties. Who knows? Maybe not. Perhaps water is what it is and there is not much more to learn. Asserting we already know everything about water leads to dogma[2] and inflexibility. That's just one example.

Dark matter/dark energy may be a rounding error for all I know. Good. Now we know about the error. We* likely asked a bunch of other questions as well and now we have new answers about to appear because now that error has been confirmed.

* not me.

[1] being wrong about bridge structure is unhelpful as you drive over it. That kind of wrong is related but I'm not directly addressing that.

[2] dogma has expectations, rules and consequences. Science has plenty of people who forget this and turn their understanding into dogma. That too is a experience generating moment that will catch up with them later. Mountain-of-data + knowledge + wisdom.
do you agree that there are tradeoffs is system design?

A plane could weigh a lot less if we removed all the computers and sensors that it carries. However, as logical beings we make the trade off because speed isn’t as important as safety.
Well I'm designing a solar powered farming machine we hope we can make open source. A bunch of the parts can be printed on a $1000 printer. I hate proprietary technology, and I think our entire economy should consist of open/libre technology.

It definitely feels like "big business" is working against us in this regard. Everything new is locked down because the the rent-seeking those software locks enable. It's a drag on our economy and we've got to stop letting them do this to us.

To answer another question from the post:

"But do I want to do this? Asking mailing lists admins to trust me again,
with a new domain after the previous debacle, is a bit too much, isn't
it?"

I'm a list admin for a mailing list available on gmane. Granted, it
doesn't get much traffic. As a list admin, I feel that Lars -- via gmane --
is providing an invaluable service for my list.
At least for me, it's not too much to ask, though I'm a sample size of one.

I appreciate being able to use Gmane to read and contribute to so many mailing
lists, all from the comfort of my favorite newsreader (gnus).
Rather than having many sporadically-followed lists delivered via email,
I can access them over NNTP, saving disk space etc.
I'd miss it if it were gone.
If I am reading this correctly, in plain English what it seems like they are suggesting is that old Type Ia supernovae worked differently from newer supernovae; e.g. that a Type Ia supernova 5 billion years ago had a different brightness curve than a Type Ia supernova from 50 million years ago.

On its face this seems like an extraordinary claim; I can’t think of how to square it with the (fundamental) assumption that the laws of the universe have not changed during its lifetime.

It sounds like you are ignorant of the problem here.

YouTube throws up videos to children that look good until you get to the second of the video some psychopath has spliced into it. It’s literally not possible to safely put your kid in front of YouTube unless you have pre watched every video YouTube might potentially auto services up to your 3yo
For jobs there's a competitive selection process, so referrals from people who passed the competitive screening are likely to be in a top percentile.

With friend networks, most people don't have a competitive selection process - you're friends because you went to school together, lived in same area, etc.. The referral for dating isn't as likely to be in a top percentile, so it makes sense to go and cast a wider net.
It’s a how-bad-you-want-it filter. Plus a bit of an IQ test (to recognize which solution applies—of course even more studying can help here, too).

It’s working as intended.
I guess by blind I mean you did not know the person before and you have no known mutual connection to him or her.
I read with some surprise his claims that Amazon wouldn't take down a fake review (which posted fake anti-Semitic quotes, even when the publisher sent them the pages the quotes were supposed to be from). So I checked Amazon myself, and sure enough there is the number one review[1] claiming this tome continues the unfortunate slide of Patrick S. Tomlinson into an alt-right provocateur with blatant anti-Semitic tropes and characters littered throughout the book.

Ironically, most of the other one star reviews claim the book is full of "thinly-veiled, progressive tropes"

[1] https://www.amazon.com/Starship-Repo-Patrick-S-Tomlinson/dp/...
I think it might actually be the opposite.

Anecdata:

- <50% of the people who joined my team recently were referrals.

- >50% of my friends in "serious" relationships met offline.
It's all about looks and even more so these days!

Side rant...why on okcupid do I get 40 likes ..send messages to ten or 15 of them and no response. Online dating sucks! Many of those likes are probably fake created by OkCupid.
+1 These seem like they'd be perfect for it.
It feels like you're skipping through a few steps to create a specific conclusion in order to then refute it?

If a detective merely asks you "do you post signs with your name and number with an offer to buy houses", a lot more steps have to take place before reaching the point where you, personally and individually would see a fine for what is in more cases than not going to be a civil infraction that I would imagine, one can take photos of, go to your municipality and contest and say "those signs are illegal but are not mine, these signs are legal and belong to me".
Evaluating Machine Translation Using BLEU Score
I disagree. It's never been harder to compete by producing a long-term, very reliable machine.

* You have to make your machine good the first time. The customer buys it completely, no chance to update and fix things.

* Your machine is marketed as reliable. This means it has to be reliable, so you put a lot of effort / material / money into your machine, when your competition puts in much less.

* If your machine is indeed reliable, your customers won't show up for another in a few decades(!). They also won't need many spare parts. This will make your machine much more expensive up front. On a market where an average machine is priced in hundreds of thousands USD, this may be a deal breaker.

* Since you are a newcomer, there's little implicit trust to you, right when you are selling very expensive hardware much higher than competition.

It looks like everything is stacked against you.
sounds like microsoft is in it for the long hall. Hopefully they come out with more skus with top end hardware to pilot the industry forward for premium amd laptops
