Theres a desolation that settles into your soul around your late 40s or early 50s. Not everyone, but its fairly common. You have to figure a way out of it. People think its about accepting the increasing context of limitations in your life, but I think its more than that. You just dont give a shit anymore about so many things. Like going to work and keeping your boss happy. Or where you want to travel on vacation.
Occasionally this outputs F'DK'M instead of GAELAN for me. Maybe an issue with some of the fonts?
> It definitely sacrifices some important aspects of APL

It sacrifices the most important aspect: The notation.

From A Conversation with Arthur Whitney[1]

BC To ask a slightly broader question, what is the connection between computer language and thought? To what degree does our choice of how we express software change the way we think about the problem?*

AW I think it does a lot. That was the point of Ken Iverson's Turing Award paper, "Notation as a Tool of Thought." I did pure mathematics in school, but later I was a teaching assistant for a graduate course in computer algorithms. I could see that the professor was getting killed by the notation. He was trying to express the idea of different kinds of matrix inner products, saying if you have a directed graph and you're looking at connections, then you write this triple nested loop in Fortran or Algol. It took him an hour to express it. What he really wanted to show was that for a connected graph it was an or-dot-and. If it's a graph of pipe capacities, then maybe it's a plus-dot-min. If he'd had APL or K as a notation, he could have covered that in a few seconds or maybe a minute, but because of the notation he couldn't do it.

Another thing I saw that really killed me was in a class on provability, again, a graduate course where I was grading the students' work. In the '70s there was a lot of work on trying to prove programs correct. In this course the students had to do binary search and prove with these provability techniques that they were actually doing binary search. They handed in these long papers that were just so well argued, but the programs didn't work. I don't think a single one handled the edge conditions correctly. I could read the code and see the mistake, but I couldn't read the proofs.

Ken believed that notation should be as high level as possible because, for example, if matrix product is plus-dot-times, there's no question about that being correct.

I have been on a low carb / ketosis diet for a while and I find that this gives me better control of when I go to sleep and when I wake up. Might be worth a shot.
I wonder if it is the same transition that an illiterate adult goes through if and when they finally learn to read. Most of us probably don't remember the feeling of doing that when we were young children.
That was brilliant. I completely agree that there is no other way to bring the Republicans back from the brink but to beat them for as many offices as possible.
Similar age, and I experience this most when I'm depressed (which is mostly seasonal for me, winter is often very unproductive and very foggy for me, if I don't get myself to somewhere with some sun).

Getting my depression sorted usually sorts the fogginess and mental sluggishness. Though I'm confident I'm not as quick witted as I was in my 20s and 30s. I have a lot more knowledge and a bit more wisdom but I'm not as "smart" as 25 year old me; I'm nicer and more empathetic, though, so that counts for something.

When I'm not depressed learning new things is slower and a bit more labored but not hugely so. I've been getting back into serious music study after years of only casual playing and I think I'm learning new pieces and techniques at almost the same pace I did when I was younger, though I'm basing that assessment on recollection which can be hazy after ~20 years.

I think there's also a tendency to lose the growth mindset as you age. I struggle with it sometimes. When starting a new project where learning a bunch of new stuff is required, there's sort of a grumpiness about it...it's like, "I've already learned and done real work in a half dozen programming languages, why do I have to learn another one?" With a dash of "I'm too old to be wasting time on these detours into obscure territory. I'm already an expert in all this other stuff, I should be focused on maximizing the value of that expertise." Even though, honestly, learning new stuff is more fun than the actual building things and using existing expertise is often boring and predictable; but this mindset gets in the way, anyway. It's quite a pickle to be in.

Think of the quality of life that could be achieved if we take all the money from the drug cartels and use it to feed and shelter the homeless of the world.

It's a nice sentiment about an idealistic world but ultimately meaningless beyond producing feelings of guilt for the target.

How much should cellular service cost that covers an area as wide as the U.S.? I currently pay $220 a month on T-mobile all taxes and fees included for unlimited data and voice on 5 phones and an iPad. 2G roaming in most of the world and faster roaming in Mexico. I also get 10GB of 4G tethering on one line and unlimited 512mbps tethering on all devices. We also get a family Netflix plan included.
Work is the default, and it will consume as much time as you let it.

In my experience there's nothing more to figure out than setting the boundary and enforcing it on yourself.

Having said that, everyone has time to do as many pushups as they possibly can on a daily basis. This alone will make a substantial difference, and after months or years of doing this, you'll be both feeling better and in a much better position physically to do something more time-consuming like running.

Before you shower every morning, get on the floor and do pushups. This probably only takes a minute of your time in the beginning. Gotta start somewhere, quit making excuses.
I never went to burning man, but I definitely want to attend one of those years.

That being said, I cannot stand the Koolaid that you basically hear from everyone coming back from Burning man. It usually breaks down to the fact that Burning man is a perfect inclusive society and that everyone loves happy there without money and that's what society should be.

SURE, but never forget that the extremmely vast majority of the people at Burning man are rich yuppies from San Francisco or Bohemians//Artists that managed to find a way to live on the cheap.
I'm pretty sure you will not find a lot of representation of average americans that can get only 10 days off a year.

And here's some extra info that accompanied this data:
"The growth in the rich and upper middle class and the declining proportion of the population in the middle and lower classes indicate widespread economic growth between 1979 and 2014, but that growth was not distributed equally. On average, incomes grew 53 percent over the period. If the growth had been equally distributed (figure 3), then the shift upward would have been much greater. At the extremes, the proportion of the poor and near-poor population would have dropped to 12.8 percent, and the proportion that is rich would have barely increased (to only 0.5 percent of the population) because the growth among the near-rich with even growth would have been much less than what happened with uneven growth. With even growth, the size of the middle class would have declined but the growth in the upper middle class would have added another 6 percentage points and reached over a third (35.2 percent) of the nondependent adult population."

This is a wee bit disappointing in its analysis. If you fancy a better background read into some of the dystopian TV series of the 70's (I'm 51 so this is the era of UK TV I grew up watching as a child) then get a copy of "Scarred For Life Volume One":

The most irritating thing with these competitive/algo stuff is that no matter how many times you master it - eventually you always forget it, because you don't need it on a daily (or more like yearly) basis in the real world.
I created my own starter about 4 years ago and have been feeding my little family of four using it ever since. I'm very happy to not have to buy that terrible bread that they offer in the stores anymore.

My understanding is that it really doesn't matter where you get the culture from. It takes a couple of weeks to get a starter started so if you want to get into sourdough baking I'd recommend just buying one if you can get one from anywhere else.

(I created my own mostly out of curiosity, it's fun, but it takes a couple of weeks)

I often hear about how for example the sourdough bread in San Francisco is special and that this has something to do with the culture. I don't think this is the case. My understanding is that you tweak the taste using temperature and proofing time (and flour mix, obviously). Personally I don't want my bread to be sour, so I generally feed the culture frequently and proof the dough at around 27C. If you lower the temperature and proof for longer you get a more sour tasting bread.

If you just want to make a tastier bread then simply using very small amounts of baker's yeast and a long proofing time (at low temperature) will get you very far. It takes time to develop the flavours and the main reason the store bought bread is so bad is simply that it's produced so quickly.

Oh and I can also recommend the dutch oven trick, with sourdough or not, it really is a very simple way to make great bread at home.
PDF is interpreted PostScript. It is not a programming language as PostScript is.

Edit: PostScript has to be interpreted and rendered, PDF only has to rendered. You can't jump to page 100 in a PostScript if you haven't interpreted page 1 to 99 before. A PDF can do that.
At least the school my fiancée is currently attending (Kellogg) is decidedly not stuffed with people 2-3 years in investment banking. A lot of people here are exactly the same graduating class (2011) because of the almost mandatory 5 years. There are exceptions, but a large portion of the people I've met during these past two years are exactly my fiancée's age.

Manufacturing companies usually have to run this through preprocessing in order to make the interference lithography work properly. In the end, they produce a bunch of IC masks, and it's always possible to ""manually"" (with expensive tools) cut another hole in the mask.
I've wondered something about dreams that if taken as explanation is very similar

Conjecture: during sleep the mind moves short term to long term memory, when formed, the memory fires adjacent nuerons and these fired nuerons form the dream

In your case, seeking an old memory may have fired other adjacent nuerons, perhaps ones that have been dormant for some time

I will do this when trying to remember something.. think around an memory and my own exposure to it contextually hoping to indirectly find the desired memory
Yeah, understanding the internal combustion engine should not be a prerequisite for riding a bus.
That's fair -- I'd forgotten the context of the quote I picked out, as it's been years since I read this article.

Generally when it comes to a medication you're expected to take for years or the rest of your life, I'd want very strong evidence in its favor. The well-known problems and biases in biomedical research mean I need to consider a wider range of claims than the most official reviews, unfortunately.
When Gmail first rolled out, this was one of the most often asked questions. The usual answer was that the question is wrong, because Gmail is different and one doesn't need sorting. Fast forward 14 years and users still have to use workarounds like size:20m (that appeared in 2012 IIRC). It doesn't show message size either as if it didn't matter at all.

I think you're overstating the effect. Most people I meet at Kellogg (I'm not attending, but my fiancée is) are here with 4-5 years of experience.
Is it really though? How do you convert your dirty money into cryptocurrencies without leaving a damning electronic paper trail? Buying them from strangers in the food court at the mall? Surely this channel is not sustainable at scale.
When snoozing with Inbox, did it allow you to type in a snooze time that would be interpreted intelligently (e.g., "8 hours" or "3pm May 5")? Or does Inbox only allow you to select from a predefined list of options ("tomorrow", "next week") or use their clunky date picker? Both Streak (a Gmail plugin) and FollowUpThen (an email forwarding service) allowed you to type basically anything, which was way faster.

Decoupling capacitors are in a unique position: practically every bit-flip in a chip turns into a glitch signal on the power lines. Normally the capacitor is there to supress those signals by shorting them to ground, but it's also ideally positioned to analyse them.

Yeah, this merger (for whatever reason) reminds me a lot of the US Air/American Airlines merger of a few years ago. On the one hand, going from 4 to 3 'major' players seems an obvious loss for consumers. On the other hand, unless these two combine, I don't really see either of them able to really challenge AT&T/Verizon long term, which means that a merger to create three large players is better for consumers than a series of events that ultimately ends with two major players - and that seems like a fairly realistic outcome in this space.
What's so righteous about the status quo? I'll put it to you as succinctly as possible:

I can hold money in a checking account and have the same amount of money next week, or next month

Inflation is largely predictable, and pretty much non-existant compared to crypto volatility

Fraud, phishing, and hacking will not cause me to lose my life savings. My mother is not technologically savvy at all. I would be terrified to let her keep any significant portion of her savings in a system where a hash with a typo will cost you you everything.

For as much as cryptocurrency supporters will harp about the evils of Wall Street; the explicit scams, pump and dumps, and market manipulation by 0.001% of crypto holders make Goldman Sachs look like a company of boy scouts. 2008 Financial recession? Ha, wait until you see what happens when Chinese mining pools decide it's time to weed out the small fish (ie, every other month or so). Sure, lecture me all you want about how the Federal Reserve is evil - but at least they don't prey on investors with explicit pump and dumps, useless ICOs, or that shit circus Tether.

Although there are certainly smart people working in the blockchain space - most cryptocurrency/blockchain supporters are needlessly confrontational, smug, have a limited understanding of economics or financial engineering, and use ad hominems when they're confronted by arguments they can't debate against.

From an economics and engineering perspective, there are a lot of holes in blockchain and crypto as a technology. This is reflected in the fact that there are currently no useful innovations built on blockchain, other than money laundering, and cryptocurrency (which has no inherent value itself).
And it requires users that want to override it (a common issue with final stuff on Android) to use native extensions to patch the memory of the parent class at runtime (or use other forms of reflection).
I certainly didn't mean to imply (nor state) that a net worth of $5MM was middle "middle class", merely that someone with $1MM was technically in the dastardly "millionaires and billionaires", but wasn't someone that confiscatory and redistributive tax policies should heavily target, and that single digit millions wasn't outrageously wealth hoarding.

If our family had $5MM net worth and paid off our house, we'd be looking at a passive income stream of somewhere around $120K/yr, or about what two median public school teachers make. That's hardly Scrooge McDuck or "day drinking mojitos on the fantail" territory...
> with fewer easily processable resources available

I don't think that that is true. For one, the meaning of "easily" shifts all the time, second, I don't see the problem when people actually have something worthwhile to do with their lives.

I am very concerned about what we do to the environment (as someone who had chronic heavy metal poisoning treated by chelators in a university clinic when I hear about mercury in sea fish it actually has a deep personal meaning), but that is a different issue than resource extraction (which of course may make the environmental situation even worse).

On the other hand, I see researching and developing capabilities to understand and manipulate the environment on a large scale much much better as a very worthwhile economic endeavor. For example, this also gives us a starting point for future projects in space, including "terraforming". It's obviously something we could have lots of fun developing - instead of selling insurance, "financial tools" (on top of financial tools), and other BS "products". People working in that sector, which could very well be(come) a major part of humanity, would not have the problem of finding their job meaningless, as so many do today. That the control system we use to steer humanity is incapable of steering us into such an obviously useful and worthwhile direction, but instead steers us towards environmental destruction, creating meaningless jobs, gets people to cheat one another like there's no tomorrow and being honest actually takes a real effort tells me our control system is really bad and out of control. Th eproblem is that the control system (e.g. "finance") has become the final target, instead of being seen as a tool. Instead of optimizing the tool for society we try to optimize society for the tool ("everybody has to be in the stock market - for retirement!" -- Wallstreet approves).
> It seems like BO's engines are smaller and/or have deeper throttle capabilities, so they actually do hovering and controlled descent.

Blue Origin only uses one engine for New Shepard, so it's actually proportionately much larger than the Merlin engines on Falcon 9. The reason they can hover is that New Shepard is fundamentally a MUCH lower performance vehicle than Falcon 9. This allows them to land with a larger fraction of their launch mass, decreasing the amount of throttling required.

The single BE-3 engine used by New Shepard can throttle from 490KN to 89KN, about 18%. The 9 Merlin 1D engines on a Falcon 9 first stage can throttle to 39%, but 8 of them can be shut down during landing for a total throttle capacity of 4.33%. The fact that New Shepard can hover with 18% throttle but Falcon 9 can only do a suicide burn with 4.33% should tell you everything you need to know about the relative performance (and use cases!) of the two rockets.
Ask HN: Working as programmer in science?
I started programming during my post-grad in nuclear physics, but after the post-grad in fundamental sciences I went to industry and for the last 4 years I've been working in web development. I kind of long for somewhat more meaning in the product I'm working on. More in the sense that it's not for buying-selling stuff online, but for helping scientists. (For the record: I don't want to be a scientist again, because I'm very happy with being a programmer.)

Does anyone here work (worked) in a research center as a full-time programmer? Could you tell about your experience there?
I've heard the argument before that you want to encourage, as the article calls it, rent seeking because it demonstrates flaws in the market/regulation and if more people exploit them they become more visible. When they're sufficiently visible they can be addressed by the public. It seems like this cycle must exist in order to make progress in economic regulation. It also feels like a society needs a strong leader who can unite people under a preferred economic policy in the first place. No progress will be made endlessly bickering over preferred political ideaology and thrashing on regulatory laws and guidance. How do you make progress in the US where we endlessly bicker over policy direction and have marginalized the utility of a strong leader? I don't know.
