"LED's are nearing theoretical max efficiency, somewhere near 220lm/watt for pure white light."

Cree has already hit 300+ lumens per watt at room temperature and 1W power throughput, and are showing no signs of slowing. The problem with LEDs is not wave issues, but the Auger Effect where electrons recombine with the LED junction material instead of going through the electron hole.

However, CRI is still meh. For gem work, you want sunlight or incandescent, nothing else is acceptable because you need a true blackbody radiator. LEDs work fine for isolating and orienting stars, adularescence, schiller, and sheens, but are horrible for tenebrescent gems, some dichroic gems, and such.

Also, some LED-covered wavelengths are still utterly useless when compared to other sources. UVB LEDs at their best are only about 2% efficient. You might as well stick with a raw phosphor-less fluorescent tube with glass filters for UVC and UVA on it at that point, you'd still push roughly 30% efficiency.

Red LEDs are also still rather meh on the efficiency scale.

I wish they'd just build something simple, like AREXX. There's a reason AREXX ports were in almost every AmigaOS app: It was trivially simple to get started. The network effects were huge - pretty much any app was simple to automate. People to some extent built their apps as message pumps where input events (mouse, keyboard) triggered the same command hooks as AREXX messages, so every little piece of the app was scriptable.

If you wanted a more advanced API than AREXX could reasonably accommodate, it was easy enough to layer the more complex bits next to it.

The threshold for people to take full advantage of DBus is still too high. Maybe there's a need for something that complex for inter-application communication, but if so we'd also benefit from something simpler.

Maybe it's just a documentation failure... I don't know.
Should the electronic brain managing these funds do something smart in the event of a down turn? It would be nice if these funds made more rational choices than humans.

This is sensationalism at its best and repeats what people have been preaching for years, one big example being Ray Dalio https://www.youtube.com/watch?v=PHe0bXAIuk0. The fact the US market is probably in the late cycle says nothing about how long that could last or about the state anywhere else in the world. Yes the Fed will be raising rates, yes money won't be as cheap but there are still companies making products and making a difference in the economy. There are still good investments to be made in emerging markets, which are less mature in their cycle, and even can be found in the US's more mature part of the cycle. I don't know how many fund managers invest strictly according the the cycle, I'd say 0, but instead use it as a piece of information to help make their decisions and help rationalize valuations, metrics, etc. Regardless, diversify your holdings from just US securities (again something that has been said forever) and if there is a market downturn, it will probably come back up eventually. It is, after all, a cycle.
> That doesn't seem the central assumption of Anthony here,

Yes, that's my point. It's the interviewer who has this idea that faith should be reliable and that's what I was questioning. Or did you mean the interviewer (Anthony with an h) ? I am a bit confused right now..

No they weren't.
Maybe others think differently but I see those two companies as a way to set it & forget it invest. I can afford to invest $X every month. I'm going to put it in a robo-ETF company & not think twice about it. That means not paying attention to the market at all & playing the long term.

The only thing I might do, which contradicts what you suggest, is try to increase my input each month during a bear market if I can afford it.

Downturns usually happen sometime after GDP reaches the potential GDP. Timing the downturn is almost impossible. It relies too much on 'animal spirits'. Downturn within 1-5 years is very likely.

Illustrative picture:

for those of us in the bottom 95% of incomes the downturn has been going on 30 years.
Other thing: Their entire revenue stream is based on percent fees from current assets. During market downturns, total assets drop, which means their revenue drops. Not only are more of their customers likely to withdraw funds during a downturn, but the companies themselves have never existed during a downturn.
I look at crypto as a deflationary asset class that can't be influenced by central banks as much, so they might withstand the credit contraction cycle rather well. There are factors that make the whole equation complicated like: regulation, small market cap, hype, relative novelty etc.
Eh, you prefer using bind() or something? Because that still creates another function.
I've got friends in the Canadian version, WealthSimple. They've got some pretty good writers that put out articles related to money and saving and what-have-you and wrote this one a little while back:

They really seem to want to help educate their customers. Of course, they want to do this because the more educated they are on the matter, the less likely they'll pull their money out.

There is something to be said for simplicity but it gets worse with time and exposure. Many of these older cars have first run issues like exotic oil types or vanos type engines + known mileage warts and expensive replacement parts.

I used to drive old used junk all the time and the truth of the matter is that the newer the better and you will miss what you don't have. Yes, the car industry is a racket but keep in mind that a car is not an investment except in some wealthy circles.
Sardinia's virtual currency
"Antivirus can actually open you up to certain attacks with memory corruption vulnerabilities in the file parsers that automatically run."

Yeah, I thought the idea of firewall == snake oil was pretty well-accepted among computer-literate people. The kind of people who might benefit from it will just make an exception for malicious software without reading the prompts, and power users know what to download.

And in addition to that it makes people even more insecure as it promotes a false sense of security. It seems that having a firewall makes people even more likely to turn their brains off and clicking "yes" on any dialogue without reading it. Favorite quote after finding malware on someone's system: "But I have a firewall, this is impossible!"

But most importantly is probably the viewpoint of the top comment: Banks and other companies have changed the narrative so that users are responsible for their poorly implemented security features.

This is quite absurd, when you think about it.
The rational thing is to buy more cheap stocks during a downturn. The is called "rebalancing".
I'm so filled with dread by this future we're heading into. I'm 29 and I feel impossibly tired because whatever I do I'm heading the same way everyone else is and it doesn't look good.

Sure, lots of things will get better, but I don't think it can get better overall when we're giving this much knowledge of human nature to companies that'll certainly leverage it against our rational interests.

The more I read about neuroscience and modern psychology, the more I realize how much of our more basic (in the evolutionary sense) intuitions can be exploited by people that know how to, and this much information gives them that. It's been done before, yeah, but not to this extent and it worries me to no end.
Most likely because this research seems to deal with materials that emit, and not absorb.
There are some cars that already do this.

It's a lot simpler with independent electric motors per wheel, but generally not that useful as self drivings cars can already parallel park just fine.
Agreed. It seems like a great deal of engineering distractions from the core problem to solve. Seems like they were using precious resources to fluff up a potential keynote and make a car from a scifi movie.

Yeah, Skyrim was a major break from the earlier Elder Scrolls games by abandoning pre-made classes. It's probably a good idea in many ways, but you run into a similar problem if you want to level up in skills that aren't actually that much fun (which is basically anything except fighting.) If you want to be a master blacksmith, instead of spending time re-reolling, you spend it... crafting hundreds of iron daggers.
On top of that, I'd consider adding a bit of idempotency to the form submission -- to make sure that if the request did in fact succeed even though you did not get the confirmation of a success, subsequent retry/resubmit attempts won't result in duplicate entries.

A rough way to do this would be to add a hidden UUID value in the form data that is generated once up front and used by both the client and the server to ensure that the result of the first successful request can be cached and re-returned.

Serious, non-snarky question: In what way is a book better than a link on Hacker News or Facebook?

The problem I see (and have yet to get a good answer for) with all of these extreme productivity tactics like shutting off all internet access is that carry a value judgment that older > newer, for all values of information absorption. It reminds me of how some of the financial advice for people in debt is to eschew all forms of credit and live on cash only. Which is fine until you need to buy a house...

If the problem is being distracted from the real world, and that's truly a negative, rather than filling dead time that couldn't really be used for anything else (waiting in line, etc), being absorbed in a book is functionally no different from being absorbed in a newsreader app. With that in mind, where and why is this value judgment coming from?

I see a poster upthread mentioning we've "forgotten how to be bored".

I don't know about people here, but I saw boredom as an awful state of mind even before the proliferation of smartphones. Could someone help me understand what the bigger picture here is?
The downturn cycle is every ten years it seems. Is there a similar recession cycle? I can only think of 3 instances where the recession was substantial in both unemployment above 10%, big drop in GDP, and length of time it lasted:

- The Great Depression (1930)

- The 1980s recession (1980)

- The Great Recession (2008)
It will, if nothing else, demonstrate the utter idiocy of thinking a real estate developer understood the economy better than a professional politician. Except that the evidence will be explained away by anyone who believed that in the first place.

Downturns do favour anti-establishment candidates, so I'd pay attention to the Bernie wing in the next few years.
If systemd does it right (just like it did with making service management) then I see no issues with this.

Indeed, thanks for the pointer! Removed that now (it was left-over from before we got SELinux support).
Whats scary is we are still basically in pump mode from the last recession. The gov will not have much power to "fix" the next one. Not to mention the major debt many states carry now such as IL.
Generally robo-investors do the same thing all the time:
The portfolio expects to have these holdings at these target percentages of the portfolio. If one holding is low and another is high (by more than some specific margin) sell a bit of the high one to buy a bit of the low on.

This eases your fall in a market where different things are falling at different rates, theoretically.

>They claim is biased but is it really biased? How do they know? I think this is just making up excuses so they can collect more data.

Informed, constructive opinion there.

One clear sign of the bias is that the crash rate of the browser goes up massively every time a new version transforms from beta to release. Clearly, it's not renaming that string that makes the browser crash. The populations are just fundamentally different.

To give an obvious example, beta users are overwhelmingly more like to have up to date video drivers. (Which can be seen in crash reports, but is also very logical).
A 4dr crew cab can haul the kids to soccer and move furniture all while requiring one parking spot. It's a good multi-tool at the expense of operating costs. The cost of insurance, registration and (possibly) parking buys a hell of a lot of gas.

Think of a vehicle as having indoor storage, long term comfort (space to not be cramped) outdoor storage and passenger capacity. Crew cab trucks are used like full size sedans with outdoor storage instead of a trunk. That's a pretty good blend for most use cases since most people can use the second row as a trunk when not carrying passengers.

Insurance, registration and parking costs are a disincentive to buy specialist vehicles (like the electric commuter cars HN loves).
I think the naming is counterproductive. How many things exist that are called "NEO" these days?

This article mentions assets decoupling from the price of oil. I've found that the price of oil is generally useless: either people think it will cost more to move things and they then reduce their expectations, or they think the oil companies are driving the economy and will make more profit, and then they increase their expectations. This all seems to depend on which side of the bed they get up on.
>capitalist crisis

If not liking your boss is a capitalist crisis I much prefer it to the current socialist crisis going on in Venezuela.
I'm not sure we can get a bust when all the major reserve banks (especially the US Federal Reserve) keep propping up the economy. The real question is how much longer can investors take advantage of this? We've basically been in QE since 2009 (almost a decade?). The real test, as said in other comments here, will be when the US Federal Reserve pulls back. If the markets can take the burden then it'll survive but maybe at a lower rate of growth. If they can't bare any burden I think we'll see it immediately.
Passion for your job is overrated
Each standard deviation of excellence earned along any dimension extracts a greater toll on all others. It's good to have a specialty along one or two axes, especially given that you may not care much to be good at the grand lot of the other available skills you could attain. But to truly excell (3 or more sigma, let's say) is time-expensive.

Agreed, although if you look at the code, they do in fact do that - it's only removed from localStorage after receiving a 200 status response. Any other status code will leave the data in localStorage and display an error message.
They definitely should have not wasted time with multitouch and just used a stylus and a physical keyboard for iPhone. Right? Any time someone says “no stylus” it’s time to refocus right? After all, that just isn’t how portable devices in 2002 already worked?

Apple doesn’t care about incremental improvements when talking about a new product category. They look to leapfrog. Have you considered the benefit of spherical wheels? I haven’t, but I am not part of that project.

Incrementalism would have been making a better Apple Newton or a prettier Palm Treo. Or a slightly better Tesla. Why bother entering the car market if you’re just going to marginally compete with everyone else?

It seems like you don’t get Apple or their history of product development.

How Political Conspiracy Theories Are Born: 3 Case Studies
I am probably one of the few techies in the world that does not own/use a smartphone. Since 2011 I have used a cheap Verizon flip phone for exactly this reason; I want more control over my life. NOTHING is that important that I need to be plugged in 24/7. My wife has a smart phone which is great for when we travel (maps, Yelp, Fandango, Uber, etc.) Don't get me wrong, I was standing in a long line outside the Apple store the day the first iPhone came out. However, over the years I came to realize that in order to have the amount/type of work/life balance I desired, technology would have to take a back seat to my relationships and interests outside of my career.

I haven't looked back.
Show HN: ClearPrice.co – Glassdoor for SaaS Pricing
I spent a few years running my own startup and helping get another startup going as one of the first employees (we went from 3 employees to almost 40). A lot of my time went into finding pricing for various services, which is a huge waste when there's so much to do at an early stage or growing startup. I didn't want to spend time on demos and phone calls just to find out it was out of my budget.

ClearPrice will let you know right way whether or not it's worth using that time talking to a salesperson or going through a demo. You'll also know if you're paying a fair price for the service you're getting by letting you see what other companies your size are paying.

> A common answer to all of this is that if people refuse to contact you using other means, they are not really your friends.

People who make this claim ought to stop speaking out loud to their friends, and insist on communicating in sign language only, or by writing things down on paper. They might realize that their friends aren't really their friends, either, when you start insisting on making them jump through arbitrary hoops.
Do you text?

EDIT: someone downvoted me, probably interpreting my question as a snark. It was a serious question: I'm considering to do what you are doing and I'm wondering whether you ditched texting too and whether that got you social repercussions.

In my country it's a bit more complicated even because everybody WhatsApps and nobody uses SMS, so a true dumb phone won't cut it if you want dumb + text.
Burnout and Twitter fatigue
The antithesis of predicting that the eventual downturn will happen is "it's different this time" claiming that the cycle has been broken and there is only upturns to come.

The former are always right and the latter are always wrong.

There have always been a unlocked phones. But, in many cases these phones did not even have data ports, just the built in connection to a walled garden unless you physically opened them.

The whole point is that many programmers, even in Western Europe, are not that expensive. When one makes less than $20k/year, those "mere" $4k suddenly pay for a full trimester of work, rather than less than a month.
The concept isn't novel. In fact, I would argue that they're late to this game. I am using Scripbox for a while which works fine. As I see, they're not launching their own fund, they would be investing in existing ones, which kind of makes "Vangaurd for India" a misnomer.

I think the addressable market is huge, partly because the major things allowed in the tax saving section 80 (C) are life insurance premium, a government backed retirement fund (PPF), and long term mutual funds. The last one is the easiest to invest into. That means it's relatively easy to onboard working professionals if they are want to save tax in that section.

One issue is that the public isn't knowledgable enough about merits of equity markets. For some, it's a gamble and would rather go with fixed-rate funds.
