A 1.2x speedup affecting a primitive operation is huge.


Losses of ten percent on these nutrients do not seem like that big of a deal. Worst case we can enrich. Climate change is an enormous problem. But the nutrient levels in rice are an invisibly small speck on the face of that problem.

Don’t get me wrong. This is interesting, and the research is important. But this comment is for people like me who sometimes feel the news is about to make them hyperventilate. You can skip that for this one.


Ten percent is a big deal if you're already malnourished, as 11% of the world currently is[1].

I don't disagree about enrichment, but this is a pretty big problem in terms of eliminating poverty and minimizing (or improving) subsistence farming.

[1]: http://www.fao.org/state-of-food-security-nutrition/en/


10% is a very big deal. We talk about trying to 'eat healthy', but what happens when all your food is becoming less healthy? This is a tragedy of a worldwide commons. Because it's not just rice, extrapolating from it, this is something that affects all plants globally. And it isn't just humans that are affected: this affects the animals that eat plants. What happens to environmentally stressed endangered species who now get less nutrient value from what they eat? This isn't an isolated study: people have been looking at this (albeit with little funding) for 20 years.

Rice is a staple for more than half the human population in the world, and hence anything that affects its nutrition profile is bound to have a huge effect on several countries, their policies on healthcare, hunger alleviation and poverty alleviation. Enriching rice may not be easy to do at this scale across many countries.

The Wikipedia article on rice [1] says:

"Rice is the staple food of over half the world's population. It is the predominant dietary energy source for 17 countries in Asia and the Pacific, 9 countries in North and South America and 8 countries in Africa."

[1]: https://en.wikipedia.org/wiki/Rice


I think the impact is greatest on those who rely on rice as the majority of their sustenance and can not afford to purchase enriched goods or supplements.


How do you enrich rice?


Not only can you do it, it's Federally mandated in the U. S.: https://www.law.cornell.edu/uscode/text/7/1431c

As to how, my understanding is that it's just coated with nutrients; easy peasy.


A lot of people wash rice before cooking it which also washes the enrichment off it.


Thanks

Getting married is expensive? How so?


The legal fees themselves aren't very expensive. If you can resist the societal pressures to have a large and extravagant wedding with many guests, then even the wedding itself isn't particularly expensive.

The main cost of getting married is getting divorced. Legal fees add up a lot here, and the division of assets is costly.

Now, you could argue your marriage won't end in divorce, but 60% of marriages in the US do.


Perhaps worth noting: that "60% of marriages end in divorce" number is quirky when you pull back the skin.

60% of marriages end in divorce, but most people who marry do not get divorced from their first marriage. The 60% number is bumped out due to the segment of the population that get married 3 or 4 times.


Interesting, thank you :) I'm still seeing divorce rates of 30-40% for first marriages, depending on generation.

Anecdotally, I know a lot of people who are either divorced in their 30s, or still unmarried in their 30s. Considering the difficulties a woman has conceiving beyond their mid 30s, I think the explanation is here in our faces.

My grandma had 5 kids and was married at 19.


> My grandma had 5 kids and was married at 19.

Funny that you've mentioned correlation and no causation, and then brought this up. How old was your grandma when she had her first kid?


That division of assets is cheaper if you married someone who earns as much as you.


Getting married in a traditional way is cheap, but most people blow off tradition to get some fancy pinterest barn, with fancy pinterest lights, with some fancy pinterest minister, some fancy pinterest vows, and fancy pinterest invitations. We paid $80 for a marriage license. The church was free. The ceremony was free. The celebrant was free. The wedding was free. We also got married in the most beautiful church in San Francisco (in my opinion at least)

We were going to use the church hall for the reception, but my parents wanted us to get another reception venue. That would have been free. A traditional cake and punch reception with some music would have set us back maybe $300, but even that could have been foregone. My wife's parents didn't do any of that. Just got married the old-fashioned way.


I am really happy for you, and wish you the best in your marriage :)


Let's not mention the taxes for getting married w/out children. Unless you have dependents (children) or one income (which makes one spouse the other spouse's dependent), getting married as a DINC (Dual Income, No Children) is a fiscal disaster in the US right now.


You won’t, because you were smart and rented instead. :)


haha, but what if it doesn't pop and we see something like Japan's economy from the early 90's on? High prices that never come down, combined with wage stagnation? We're kind of already seeing it now.


You can then move to a flyover state in the mid-west, and buy a palace for the $100,000/year you were stashing away.


This is the future. Silicon valley rent problems are a network optimization problem best solved by pushing resources to the edge of the graph.


Ya it has to be. We have so many square miles of underutilized cheap land between the costs it's crazy. The federal government owns around 60-90% of the land in the western states too. If only there was a way to communicate without being face to face.


Especially with the type of technical work that's so predominate on the west coast.

A lot of that work could be moved to cheaper interior parts of the country.


Yet for some reason tech giants insist on building more opulent, centralized megaoffices in unaffordable areas. Perhaps it is because they do not bear the brunt of these costs.


One reason is that the executives who make the decisions on office locations can easily afford to live nearby. And most of them prefer to live in fashionable areas.


Japanese real estate has been in a hole for a long time. It's significantly cheaper to live in Tokyo than in a major US city now.


Wages have to stagnate for a whole long time for our 200k+ salaries to lose their value.

I'll worry about that in 10 years if that happens. Plenty of time.


Woah, when did renting became the smart choice?


As a thought experiment, imagine that you could rent a million dollar house for 1$/year. Then renting is obviously the smart thing to do. So rental yields are an important factor, as are your expectations of house price growth, opportunity costs etc.

But if rental yields are low (as they are now) and you do not expect house prices to rise at a fast rate in the future, renting can easily be the smart choice.

Regarding future house price increases. It seems to me that house prices can be approximated as a function of rents, interest rates (determining required return on owning a house), and anticipated growth in house prices (which again can be decomposed into growth in rents, reduction in interest rates and 'irrational' growth). Using London as an example. Rental yields appear to be around 3.5% in London at the moment, which suggests to me that a good deal of anticipated growth is priced in. But where can that growth come from? Rents are a function of incomes and are unlikely to outpace inflation. Interest rates seem to be more likely to go up than down. So it seems that house prices are unlikely to rise, and once that is realized by the market, prices may even come down as participants stop anticipating growth just because "London house prices always go up".

House prices going up faster than rents in recent decades can probably be explained by interest rates being in a downward trend over the same decades. Now we seem to be in at least somewhat of a bubble due to irrational future growth expectations.


I'm general, when the price-to-rent ratio is too high. Last I heard San Francisco averages >30. It only makes sense (financially) to own if the price-to-rent ratio is under ~15. If you're an investor looking to become a landlord don't even consider buying a property if the price-to-rent ratio is greater than 8.

Its a smart choice in other situations too - like when you are intending to live somewhere on a temporary basis, for example. You would certainly be better off (again, financially!!) if you were renting a room for a couple hundred bucks a month if that allowed you to sock away $2,000 a month into your retirement funds. That's provided you have the ability to actually save/invest the extra money you have, a mortgage can act like a forced savings account for some people.


Its too late to edit this post, but I should be more clear that the parent post is a major generalization, your individual factors will vary if it makes sense (financially!) to rent vs buy for your primary residence. Price-to-rent ratio is a big factor, but not the only one. There's also a lot of luck and factors out of your control that contribute to if you make out ahead (financially!) either way. I just looked up the data on Zillow and the average P/R ratio in San Fran isn't as bad as I thought, but still extremely high.

Anyway, when you're talking about buying vs renting you're also heavily involving non-financial factors that are usually MUCH more important than financial factors (assuming you have some sort of a budget); so something might be a "smart choice" for an individual but not the most financially optimal one. Just like eating lentils and ramen noodles every day might be the most financially optimal choice but is probably not a "smart choice" for most people. In fact, if you have a family you probably aren't going to make the most financially optimal housing choice unless you absolutely have to.

A real world example:

I have friends who are renting a decent single family house with tons of land for an absurdly low price (family price!) and the landlord (family member) even pays utilities because it's just "easier" and she isn't trying to make a profit. Factoring in depreciation and amortized repair/upkeep costs the landlord is almost certainly subsidizing their housing costs. Financially, great deal! They will almost certainly never have a chance to have a full house that cheap ever again. Staying there as long as the landlord lets them is the most financially optimal choice. However, for a number of complicated (but understandable) reasons, my friends hate it and are planning to move whenever they have saved up more and paid down their loan balances.


There's a great writeup on this -- I may have even seen it here [1]. On average house prices tend to keep up with inflation and trail the market across the US. In specific markets that may not be true, then there's all your expenses. Ultimately, it depends on your personal situation if you should buy or rent, and the New York Times has a great calculator [2].

tl;dr: It's not always the smart choice to buy. Or to rent.

When it became the only choice


If you were smarter you'd have commuted in from the suburbs and banked the money for retirement.


Spending your day commuting and living in a car dependent hell hole is smarter, just because you can retire a bit sooner? What alternative universe has HN transformed into?


For NYC it can be an easy 30-45 minute train ride where you are free to occupy your time with something productive.


Something productive that can be done in a car or train you mean. Not, say:

- Being with your kids, spouse or helping them out to school or work

- Housekeeping

- Working out

- Doing anything that requires undisturbed attention


As someone with a long train commute, my train time is basically my non-productive "me time". Read a book, read the internet, take a nap, program on fun, non-work projects. If I'm at home, I'm usually engaged in child-care or house-care of some flavor or another, with very little time for simple idleness.


To your last point: in NYC it's pretty easy to do things requiring "undisturbed attention" on a 45 minute express Metro North train into the city from the suburbs. It's a very different experience from the subway.

As for the other three, I guess I could say that I'm not sure it's realistic to try and budget your time so efficiently that a 30-45 minute commute is intolerable. Many people have commutes for which that's a margin of error on how long it will take them - that sounds like a real problem.

Aside from working from home full time, what kind of commute are you looking to have, and at what distance from work? It's not realistic for most people to achieve a 15 minute commute, so 30-45 in a train really isn't that bad. If it really matters then you could do things on the train that would normally keep you from your spouse or kids at home :)


I'm one of those 30-45 minute margin-of-error folks- I'd move into Hoboken or Brookyln for a 45 minute commute in two seconds!


My friend does the Go Train from Oshawa to Toronto every work day. She spends the time on the train either reading a book or watch a video of a show she is following.

On the way home she will sometimes watch a movie and finish it at home. Time on the train does not have to be work or a vegetable.


Just to add perspective here. Toronto anywhere proper, you have to get on a bus generally, to get to the station. Then you have to take the train south to Union. Then take the GO, East to Oshawa. The entire trip can be done in less than hour, but you are walking between connecting options for 10-15 minutes which limits your "free time."

The idea here is many people want a house and if you aren't DINKs then Oshawa was cheaper in housing a while ago. Now it's almost similar to Toronto cost and rent is nearing.


You can trivially get a 30 minute commute just within SF. I imagine other expensive cities are similar. Living within a few minutes of work is a real luxury for all but remote workers.


Depending on how early you retire it can be the smart choice.


That’s 2+ hours per day of your life that you’re never getting back. You can always make more money, but time lost is gone forever.

How much is 2x5x52 = 520 hours worth to you?

If you’re selling your time for even just $100/hour that’s $52,000/year right there. With a 300k salary your hour is worth way more than $100. For your family, it’s priceless.


If you commute by train it’s not all necessarily wasted time. You can read, play games, listen to podcasts, etc.

I always read many more books when I commuted than when I didn’t commute. I find myself making new year’s resolutions to read more. But it was easy when I had the commute as a forcing function. (Not having internet on the subway probably helped...)


If you don’t think reading books is valuable enough to do when you aren’t commuting, is it really valuable to you? Or are you just doing the best you can to salvage a shitty situation?

(I audiobook when running so I’m no better)


I always find other more pertinent/alarming things I need to do at home and the forced lack of internet makes me focus more than I normally would.

Admittedly this doesn't say great things about my attention span...


I think it is valuable, I’m just bad at organising and prioritising my spare time!


300k a year post tax, 50 weeks a year, 50 hours a week, that's $120 an hour.

If it takes an extra hour a day and $500 a month that's $3000 to save a month in housing costs


Don’t forget to take transportation cost out of your $3000 per month.

I live across the street from the office and yes the rent is stupid, but my commute is a 5 minute walk.

And rent is still stupid in a 30min radius (for a total of 1h/day). You really have to go 1h+ radius to make a significant dent in rent around here (SF).


I did - $500 a month. I have no idea what communitng costs, and little idea about rent.

I have a 5 second commute from the bedroom to the office (3 minutes if I go downstairs and boil the kettle first), far easier. Monthly Mortgage is less than the weekly rent that one colleague pays in London, and he still has a 45 minute commute each way.


If you are working for somebody else, you can't exactly make any extra money by working extra hours. At least in a programmers case.

The only real thing to gain in this case is convenience.


I work full time in software engineering and do occasional paid freelancing work. It's quite possible to be full time and work extra.


Depends on your contract and whether you get paid overtime.


It's essentially unpaid work. So you "upgrade" your 40 hour week to a 50 hour week.


In SF the suburbs are called Silicon Valley and are also expensive.


Sufficiently expensive that when I consider Silicon Valley jobs in my future, I also consider getting a pilot license and commuting by plane from the central valley.


There are also suburbs across the bay that are cheaper.


Maybe.

Right now though, my 401k has been doing 15-18% for the last couple of years. My condo has been going up in value by about 13%/year, but I put 20% down and I think I'm at 30-35% equity, and my monthlies are cheaper than an equivalent rental.

The rent + invest vs buy + bank on property value debate is age old, and I won't restart it here, but so far, I'm not doing terrible.


Is that commonly done? I would guess this means the withdrawn paper contains an egregious error. Does anyone know?


Go has been out for almost a decade and they’re still working on the package management story.


I’m super bullish on rust. I feel like it was designed with the right intentions.


Yep. There are some languages that start out trying to solve fundamental productivity issues in previous languages - some more than others.

I think we had a generation of ecosystems with Node, Ruby, Python, that tried to do solve the unapproachable systems around the Java/etc ecosystems and make them more open.

They succeeded, but the next generation seems to have been about solving the plethora of tools that came with those languages. Rust, Go, etc, having first-party tools are trying to improve upon that, and yes I think Rust is by far the best implementation I've seen.

I'm interested to see what the next generation is.


I love rust, but the standard libraries are nowhere near the same abstraction level of nodejs.

All services I've deployed built on rust pulls in a kitchen sink of deps.

Granted. I get a static binary as my end result, so maybe it's fine.


Rust is designed that way, to be fair. They expressly did not want to be batteries included like python is. The reasons are what they are and not particularly relevant to the conversation, but pulling in well designed third party crates is the point.


Speaking from a python user's perspective, the batteries included philosophy works great when you have a neutral implementation. Python does a good enough job, and provides extensibility in a way that I don't need to download a package to do basic things. On the other I have to spend hours trying to find a package in JS that just gets shit done. The third party package way is only required for ui parts because you don't want everything to look generic. But having a good standard library to do non user facing stuff is essential. That's why every node project ends up with a thousand dependencies. Because the language is not batteries included. There in JS there is no "one correct and obvious way to do everything" which makes doing basic programming painful.


Let alone G* when CLU had them in 1975, but lets not rush.


Food and water are pretty cheap these days in advanced countries. Very few people have trouble getting enough of them. Similarly, crime has been plummeting in most areas during the measured period. Lead in water is also a rare problem to have these days, Flint MI notwithstanding.

The main cost issues today are healthcare, education, and housing.


The people on the standards committee, at least for C++, tend to be heavy users of the language.


My theory is there ware two kinds of programs.

Type one: where all the side effects are hidden behind an OS call.

Type two: Where side effects are primary and unavoidable.

People on the standards committee universally write type one code (compilers and the like). Where the Linux kernel is type two.


Nobody doubts he knows what he is talking about. The question is whether he’s making his points effectively (no).


Can you prove swearing is ineffective? (Fuck no.)


“We don’t have to pay attention to it because it’s important to our political enemies.” Picture a man standing in the middle of a track as a 100 car train barrels down the track toward him. “Watch out, a train is coming!” I yell. “You would say that. Democrats always do,” he says, and resolutely stands his ground.
