Huh, these numbers really disagree in a couple places.

Nevertheless it seems like the most important way to minimize CO2 is to focus on grains, and that milk, eggs, poultry, pork, and fish aren't all that bad compared to the average vegetable.

And milk's easy to budget for, two cups a day is only 10% of a kid's calories.
I'm a big fan of free speech and the US fourth amendment. The idea that we shouldn't discuss ethnic backgrounds and dogmatic religious beliefs doesn't sit well with me.
I can relate, it didn't make sense to me either in the beginning but eventually the penny dropped after working with it in a past company.

Rather than give a half cooked explanation here and risk more confusion, I'll update the readme with some examples and ping you if you're interested.
No thanks. I have hobbies.
Hi, let me help you "get" it with some counter anecdata: I've lived in places where I could fully hear spoken conversations of my neighbors. When you live in that situation for a while, hearing advice like "it's JUST 2 days a noise a year" and "Just suck it up" will drive you to a homicidal rage :)
It would be interesting to compare this to "A Formal Description of System/360" by Falkoff and Iverson[1], using APL as the notation language, from 1964.

Sadly it is pay-walled by the IEEE.

Conceptually, you just need to add an extra layer of indirection to local variable lookup.
It's problematic because the article isn't about their ethnicity, and your comment boils down to "hey guys just so you know, they're Jews." Who cares? Unless you're going to tie that back to the story somehow, what's the point of bringing it up? It's not explicitly antisemitic but it is a weird thing to highlight.
Yeah that article seems like a lot of tea leaf reading to me. All evidence points to SpaceX building orbital rockets cheaper than just about anyone else before reuse, but even if not reuse should drop their costs well below anyone else until blue origin comes online or until ULA decides to shake off the crust of old age. It's not at all surprising that investors are told not to expect to take a profit for 15 years because SpaceX is focused on growth and development. I wouldn't expect them to reinvest any less than 100% of their profits at this time. It makes just as much sense to assume they raised money to keep development moving at the pace they want which wasn't fast enough using profits alone.

Despite the fact that I own a Model 3 and own shares in Tesla I often find the critics make good points and just hope for the best anyways because I want electric cars to take over and I want self driving cars to develop sooner than later because driving is dangerous and tedious.

The SpaceX hate seems much less justified to me. SpaceX has been building launching, landing, and reusing rockets for years now. They've ushered in a new lower cost space age.
Furthermore, in my experience the usually poorly documented homebrew stuff is almost always worse than whatever crappy legacy but well-documented vendor their locked into.

Where by "while hanging out in your pocket" you mean "applied a not inconsiderable amount of pressure to a specific area of the phone in a specific direction".

Oh. And of course Samsung's own phones bend in pockets as well
That corporate ownership aspect is actually a good point. I'm not well-versed on the legal complexities of international ownership or the pros and cons of corporate governance in that situation, but it's definitely something worth looking into further.

On a related note, I find it frustrating how so much residential property in San Francisco is owned by Chinese investors/real estate moguls. I have no idea what the fallout would be to limiting the ability of international entities to own so much property here, but I imagine it would help with the sky-high rents. It's not a line of reasoning I've ever seen a good write-up on, so I would be curious to understand it better.
This piece is pretty ludicrous, right off the bat:

They hire one of the best chip design teams in the world. Musk said this no fewer than two times during the presentation.
In C the variable to be dereferenced can be uninitialized or it can result in a segfault. $$ is similar though the potential space indicated by an arbitrarily long string of characters is much larger than the potential space indicated by an integer or long - really I think PHP has an advantage here since it only needs to reference it's internal symbol table which it has full control over vs. memory at large where an erroneous symbol could actually be in a program's data memory and look like it's correct - a typo'd var var would have to be either a valid symbol name or necessarily be known to be bad.

This is a fair argument. But there were other factors in my argument. That social credit scores are used to determine more than "can you pay back your credit?"

It isn't hard to argue that FICO can be abused. But what's being argued here is that we don't need, nor want, a system that is more imposing than FICO. One that affects much more of your life, such as "can I use an airplane?"

> I am happy to be paid out of the money that I went out and brought in, but every company I have talked to is incredibly allergic to any suggestion that I be paid real money for the value I deliver.

Thats the wrong attitude, generally. You are a replaceable cog - just because you wrote a billing system that takes in millions a year doesn't mean you get the cut of those millions - the value isn't from the billing system, the value is from what the company provides, and unless thats billing systems then you're not going to get a cut. You're selling what is a commodity and asking to be paid as a specialist.

What if you buy meal kit in a supermarket (common here in NZ)?

I feel it's the delivery that's worst part of these. Grabbing one while you shop or on a way back from work seems genius.

Ultimately these companies don't really have a moat. Most supermarkets deliver to your home or carry their own set of kits...

There was a couple who lived out in somebody's garage for a few years after they got married and bought a house cash. I heard if on that Dave Ramsey show or whatever, it's amazing what people do to get through life. Some are strategizing ahead of others. Here in Florida if you live in a garage you might die without a proper A/C in there.
Unfortunately it's not quite that simple. The very same real world also contains offers that are customary given on the assumption that the other side says "thank you very much I will surely come back to you about this" as part of a politeness protocol but never even considers taking the offer seriously. "Please stay as long as you like" is how the last guests of a party thrown out.
Bingo! This is one of my pet peeves!

If you want to accurately measure the cost of sending a package (or passenger, or data packet), for any reasonable purpose, you can't use the "just one more" test. You have to say, "what if I increased the load by a million units? Okay, the unit cost should be regarded as a millionth of that."

Here's a great application of the concept when Netflix tried to use the "just one more" model: [1]

>The green marketing gurus at Netflix go even further, arguing that the mail is going to be delivered to your house anyway, so the environmental cost of delivering one of their DVDs is effectively zero. ... Here, the Green Lantern feels Netflix may be overplaying its hand just a little: Eventually, the addition of new mail into the system adds up, requiring more trucks, greater strain on the mail-sorting system, and so on. Since we can’t identify the impact of one extra piece of mail, we’re better off averaging the cost of delivering the mail over each item.

It was discussed on HN too: https://news.ycombinator.com/item?id=414173
Humans are able to perceive the world due to a bunch of monocular and binocular vision cues (https://en.wikipedia.org/wiki/Depth_perception). Out of these cues, cameras are not able to offer a few. For example, cameras can't offer accommodation as they can't mimic changing focal distances like a human does. Tesla also does not seem to have cameras that focus on different focal lengths as the human eye can.

In addition, even if we can get all the cues, current computer vision techniques are nowhere near as smart to figure out a lot of stuff that the brain can. There is no general AI that can learn from one instance of a test case as the human brain can. Even stuff that is simple to the human brain can trick computer vision (https://globalnews.ca/news/3654164/altered-stop-signs-fool-s...). There is a lot of catching up to do in terms of computer vision.

A LIDAR can help with these cases a lot. It's an extra input that generates a 3D point cloud of the surroundings around it. LIDARs have their own failures but can be combined with computer vision to compensate. This is the central idea behind sensor fusion. Not able to detect if an object is indeed a few feet in front of you due to confusing parallax? LIDAR can help. Looking at a new object that you have no idea what it is cause you have never seen it before? LIDAR can at least tell you how far away it is and it's shape in addition to how fast it is moving.

Now, LIDAR is not a panacea that comes to the rescue of computer vision's failings and solves all of AV's problems but it definitely furthers what a self-driving car can perceive and deliver a higher amount of safety to the end user.
I didn't get a chance to look at the paper, but I wanted to share my experience working at two social network companies and publishing an academic paper on the topic of machine learning on a social network graph. Many people think it's necessary to use graph based machine learning (or graph databases).

In practice I found it almost always better to just use a "flat" representation and do regular machine learning (or database schemas). I would love to hear if others disagree.
I agree in theory but not in reality. But it's the same situation where the the incentives of an LP and a VC are different (not really that different compared to a PE or Hedge Fund). Just like the incentives of a founder and a VC are aligned, until they aren't anymore. There's a reason LPs with squillions to invest carve off a tiny smidge to VCs, and it's not just returns - it's also downside protection. What's true for you and me for our personal finance is not necessarily true for the Harvard endowment.
The article touches on this briefly

From my understanding, the current challenge with ultra-low-latency is scale. Will it scale to 100, 1000, 100,000, concurrent users?

At the moment, everyone in the industry is working to figure out how to provide a viewer experience that is similar, or better than the current expectations of live streaming.

Live streaming is hard. Ultra-low-latency is just as hard.

However, I'm still not sure why we need ultra-low-latency. Will it improve the live experience? Maybe.
Aside from live-action sports or significant events, do we as content consumers really need ultra-low-latency?

Generally yes, but you can stack discounts often if you play the game. Things like shoes on clearance can end up at 15% of their original price- I've gotten a wide variety of stuff like that.

This reminds me some of what I've read about Blackwing pencils (originally made by Eberhard Faber Company), which were discontinued in 1998. The originals (NOS) were apparently quite sought after once production ceased. California Cedar Products is now making a "Blackwing" pencil[0] which purports to be the "revival", but there is some criticism[e.g., 1].

I have never used an original Blackwing, so I cannot comment on those, but the new ones are enjoyable to write with. It's similar to the feeling I have when using fountain pens – they're such an improvement for the act of writing that I actively seek out reasons to hand-write things.

The specifics of this chalk story versus the Blackwing story are different, but it's neat to see the passion people have for their writing implements. And that many of these, admittedly higher-quality, versions seem to be unable to survive the decrease in hand-written forms.

As for me, I do prefer chalk to whiteboards. I've always been slightly annoyed at getting chalk on my hands and so think I would have enjoyed using this chalk if I'd had the opportunity. But I see fewer and fewer chalkboards around.

As a Hong Kong citizen, I can tell you 2 mil is a realistic number. The prices in this city is the top 3 in the world. More expensive than San Francisco. There are no longer any housing available less than half a million except for government housing which you have to wait over a decade. Half a million will buy you an apartment the size of a normal bedroom in SF.
Right, but before he wrote the will, society implicitly gives the children the right to his inheritance.

So by creating the will, he actively took that away those rights from them, and gave away his fortune to someone else.
At my last job some busybodies started inspecting whether or not we have correct licenses for everything we use and explicitly deleted IrfanView from peoples' computers because they didn't. When word got around, actually went out and bought IrfanView license just for the "not gonna let you do that" moment. It's damn useful, and I've been using it for over a decade now on every Windows machine I had. Before that, I remember using something called "ACDSee", but they must have made the software worse in important ways, because I eventually switched to Irfan.
This is just a general issue with third party code - C/C++ libraries have always suffered from this weakness. Still, I've worked in places where if we were unable to distribute our library closed source the business wing wouldn't let us distribute it at all - everyone is welcome to their thoughts on copy-left software, but a thing that exists wouldn't have existed if we could only release it open-source (and yes, we even explained how licensing worked to the higher ups)

Your claim is misleadingly stated. When you say "top 20%" in this context, people would naturally think you mean top 20% by wealth, because that had been the context previously. Somebody would have to follow your link to see it's actually about income. That's a very different thing. I've seen this particular sleight of hand entirely too much lately on HN, to the extent that I'm seriously beginning to wonder if it's merely coincidence.
Lots of posts nowadays are just people humble bragging. This was read as an honest account of an enjoyable business ride.

I notice this all the time, some folks might be really outgoing, and love to talk and drive conversations, while others are content with staying silent. But all opinions on the team are valuable.

I've experienced this first hand where I've worked on great teams, and we all got involved in discussions about equally. I think it's easy to get someone quiet to speak up (if they have thoughts about the topic at hand they aren't saying), the more difficult challenge, at least for me, is trying to quiet down the team members that go on tangents.
Medical records, but on the blockchain – the history of a bad idea
[reposting earlier comment reply as a top level comment + edited]

Disclaimer: my whole career is on the consumer software side, so I can only speak to that. I have zero insight on Kleiner as it relates to enterprise.

My first time inside KP was in 2003, working out of their office for a few months during a coding internship at Digital Chocolate. Great snacks and drinks freely available made quite impression on me as a college student.

Second time was in 2011 when I came in to pitch my first startup with Aileen Lee. It was a pre-revenue consumer play, not particularly in her wheelhouse of e-commerce, so nothing came of it. She was pleasant and professional. My only complaint was that she/Kleiner didn't seem particularly "hip". Not that VCs are particularly known for their cool factor, but for some reason I had expected something a little less square based on Kleiner's reputation.

I think this otherwise excellent article does a disservice by not mentioning Ilya Fushman joining on their timeline of key events. (It does mention him later, mostly in passing). I've never worked with him, but we have mutual acquaintances and have probably been to a few of the same parties. From my perspective as a not-total-outsider, Fushman brings some fresh thinking to a firm that is badly in need of relevancy/culture refresh. If they'd had someone like him there in 2011, for example, that would have made for a much more interesting meeting for me and other other consumer-facing entrepreneurs.

Not sure if and when they'll ever regain the kind of dominance they had at their heyday, but I do think being hipster credibility matters for consumer plays, and with Fushman on board Kleiner now has a solid chance to play in this space again.
I just scrubbed through the presentation quickly today and happened to stop on a reporter's question about why they built their own chip and at what cost. Musk said basically there were more powerful chips and less powerful chips available but this one was with in their power requirements and had exactly the power they needed at a cost less than what they were paying including R&D costs.

I can understand that rationale, it's like making custom fit patch cables for your network rack that are exactly the length they need to be.
140k base for FAANGs allow them to get a few new hire suckers, and also keep the press and glassdoor away from what they're really paying people. It also depresses wages as other companies latch onto the 140k number and engineers going into FAANGs will ask for less. Most of the money is in RSUs.

Just avoid companies that aren't paying you enough - you can work your ass off and be doing wonderful new fancy specialized work and still make 50% of the prevailing wage, because the company won't pay more.

COMPAS is only used for those already suspected of/have committed crimes.

A social credit system affects ALL citizens.

Yes, there's controversy with COMPAS and I think you'll find that those that don't want social credit systems likely don't like COMPAS. But bringing up COMPAS is off topic. Especially when you compare it to China.

Let's reiterate and make this easy:

Does <government program> dictate if you and use an airplane? Does it also dictate if you can get a loan?

If you answer yes to (exclusively) BOTH of these questions, then the program might be a social credit system. If you answered no to one or more, then the program is likely not a social credit system.

Note: The China system answers yes to both of those questions. FICO fails on the airplane question. COMPAS fails on both.
>The cynic in me thinks all these companies are just continuing to push on something people don't want because it's a gold-mine of data collection opportunities.

No doubt! And the dumbest of IoT products like “connected mattresses” should prove that.

In my own defense, I’m doing a LOT of work to never ask the user for an account or password, never logging personal data, just shipping a nice device that does a helpful thing. But.... there is an obvious temptation to RECORD IT ALL (figure out what to do with it later!), but I’d be a massive hypocrite.

For me it’ll be a selling point that we don’t care who you are just that you have a device and want to do a thing.
Their most recent post about kernels is even better than this:

https://www.dhruvonmath.com/2019/04/04/kernels/

The matrix/function stuff is elementary enough that I understand it intuitively (I suck at math), although it's neat to be reminded that given a enough independent points you can reconstruct the function (this breaks a variety of bad ciphers, sometimes including ciphers that otherwise look strong).

The kernel post actually does some neat stuff with the kernel, which I found more intuitively accessible than (say) what Strang does with nullspaces.
