Yes, and there's good reason why people wouldn't think to tack a tack box to the wall just to hold a candle. The box is holding the tacks already, so you've just replaced one problem with a different one. We don't pull all stops out to solve problems because usually doing so makes more problems. One time I had to take the bottom panel on my fridge off to switch how the door hinged. I couldn't find the last screw that was holding it in place, so I couldn't get it off. If all I cared about was 'solving the problem' I'd have taken out my tools and broken the plastic panel off and switched the door. But then I'd have a broken panel... so I kept looking and eventually found how to actually remove it.
I agree with your point, just wanted to add that from the Unicode perspective emoticons (=ASCII smiley) and emojis are
not the same.

Q: Are emoji the same thing as emoticons?

A: Not exactly. Emoticons (from “emotion” plus “icon”)
are specifically intended to depict facial expression
or body posture as a way of conveying emotion or
attitude in e-mail and text messages. They originated
as ASCII character combinations such as :-) to indicate
a smile—and by extension, a joke—and :-( to indicate a
frown. In East Asia, a number of more elaborate
sequences have been developed, such as (")(-_-)(")
showing an upset face with hands raised. Over time, many
systems began replacing such sequences with images, and
also began providing ways to input emoticon images
directly, such as a menu or palette. The emoji sets used
by Japanese cell phone carriers contain a large number
of characters for emoticon images, along with many other
non-emoticon emoji. [1]

"He starts with the assumption of 100dB as the max power but OSHA's ultrasonic recommendation[1] is actually 145dB which is 31,000x more power.. Even if you use 130dB, it's still 1,000x more power than he assumes."

It's not bad, it's that this has already been done nine months ago. The linked post isn't updated - in which case I wouldn't have a problem with it - it's just another outlet for HN to vent at the injustices of the VC world.
At least they're keeping it now. We lost many hours of stuff because they just recorded over the tape.
Interesting article from 2010. So what you are saying is that they can dedicate one core to multiple users(who hosts multiple websites) using processor affinity?
As a self funded founder I feel you that the stories about what we do are unheralded and we have different challenges than other businesses (good ones that force us to find the right answer quicker).

There are businesses that are not self fundable, though and will take massive amounts of investment to make happen. Uber is one since they need to get critical mass of drivers/riders in many cities to take over. uBeam is also one of those companies, as a whole lot of R&D has to be done to take it to market. They have a thesis and if correct will have a big impact and can only be done with some real investment (can you imagine self-funding this??). This seems like the perfect thing to invest in.

Its super easy to poke holes in other peoples business but we are also not working with all the information. Let her work!
I would classify that as FUD.

The article complains that Vanguard's 10x less expensive wrapper fund isn't as inexpensive as buying separate Admiral's share versions of their index funds. They neglect to mention the minimum investment amounts for Admiral shares nor the risk of behavioral or technical errors rebalancing that could eat away any gains you might get from maintaining a fund mix yourself across several accounts. This actually happened to me and wiped away a few months of gains.

I personally keep separate funds, but I do it because I have many accounts with varyings amounts of money and need to maintain an asset allocation across all of them. Retirement funds make that hard as does lack of fund choice in many accounts.

For people not willing or stressed out by managing their money, wrapper funds offered by Vanguards are a great option that shouldn't be confused with other target retirement funds that are based on active trading strategies. In the future it's possible they will make an Admiral version.

Also, how does one average their level of knowledge against things they don't know? If you asked me how good I was at C# 3 years ago, I probably would have said 75%. Three years later, I would say 65%.

I'm significantly better at C# now than I was 3 years ago, but I'm also more aware of the things I don't understand. I also recently saw a Jon Skeet talk and it ruined my level of self-worth.
I have long suspected that the story of "The Aristocrats" is a hoax, although I've never bothered to pursue the question: https://en.wikipedia.org/wiki/The_Aristocrats_%28film%29

My reasons for this are a) it is very difficult to find any pre-2005 citation for the joke, despite one supposed reference from 1975; b) the details of the story don't seem to me very plausible given what I know of comedians; and c) it's the kind of thing Penn Jillette would do.

So the story may have already played out in the modern era, if not in this case then perhaps in others: the 'Net is so full of nonsense and mis-information it would be very hard to tell. Social fragmentation of information sources likely makes it even easier today... you could argue that Birthers and the like are an example of this kind of hoax (or victims of it.)
What you describe is next event estimation.
HN pages are small, the HTML is generated on the server, and they render nearly progressively. That is, the renderer doesn't need to block waiting for many CSS, JavaScript, or font files to download.

Most development practices considered "modern" prevent progressive rendering. Common tools like Bootstrap or Jquery, as normally used, cause page rendering to block until large libraries are downloaded, despite the fact that only a tiny portion of bootstrap or Jquery are actually used by the page.

The largest reason of all is that most developers dismiss such concerns as old school worries and like to harp on and on about how tools like Angular enforce wonderful software engineering practices, ignoring that most such frameworks, as commonly used, bloat pages and cause incredible rendering delays.

The difficulty with improving performance is that most "modern" pages have numerous render-blocks. The page doesn't get fast until you fix all of them. This is the reason most wise suggestions to speed up a page make little difference when tested individually.

6 Startup Strategies That Turn Off Most Investors
No, forum.dlang.org is not crazy-fast. Other sites are crazy-slow.

Write compact and easy-to-render HTML, it's no rocket science. Write some trivial CSS, you don't need Bootstrap. Make something dead-simple and call it flat design. If you have more than one stylesheet, concatenate them into one. Consider minifying. You don't need a 200 kB JS framework in order to fade in some hover menu. If you do need more than one JS file, concatenate them into one. Minify/uglify and move the <script> tag to the bottom of your HTML.

You don't need 2 MB worth of stock photos. Recently, there was a page on HN with an uncompressed 12 MB banner photo. That is insane.

You don't need those heavyweight social plugins, they ruin your day (performance-wise). If your content is great, people will find a way to share. If your boss specifically asks for Facebook and Twitter buttons, just link to https://www.facebook.com/sharer/sharer.php?u=http://www.exam... and https://twitter.com/home?status=This%20is%20great:%20http://.... [1]

Don't just embed YouTube iframes, they are even worse. Use yt-embed.js [2].

Is a web font really necessary? If it is, do you really need Bold Italic? Sure as hell you don't need Ultralight+Light+Semilight+Regular+Bold, just because there is one ubercool Ultralight tagline in the footer.

Make sure Nginx or Apache gzip HTML, CSS and JS and send far-future Expires headers for all your static assets. Make sure that there are no redirects, they add latency.

If you follow these simple rules, your page weighs under 50 kB and needs no more than 10 HTTP requests. You don't even need complicated CMS caching and CloudFlare. But hey, there are some 10,000 cache plugins for WordPress, just install one.

Is it ridiculously hard to go to the nearest university and ask a physics professor if an idea is even plausible? If it is, then maybe investors should pass on stuff they don't understand.
My first thought on reading the headline was: hadn't they better get printing working first? I just assumed it still doesn't because after five years or so of not being able to print anything but postscript files to a postscript printer I completely gave up on printing on linux, because like you, no amount of messing with configuration stuff would make it work (I could on rare occasions get CUPS configured on a single machine with one printer, but it was always an incredibly fragile and delicate arrangement that fell to bits when anyone looked at it sideways.)
I'm inescapably drawn to the idea that selling goofy ideas to cash-heavy investors is a form of short-selling, and every "hot" market has a fair amount of short-selling activity going on. In fact it got me wondering why the typical startup founder isn't primarily engaged in shorting their own stock, given that the majority of startups fail. The answer has to be that the founder has enough of their own skin in the game, and limited access to pocket the cash themselves, that they can't profit from this ploy.

> 3D printers required solid model generation, slicing using either some proprietary software or solidworks, and transmission to the device over network share, ftp, or sneakernet.

These days(for me, and most of the stuff I've seen) it's solid model generation, slicing using free/open source(slic3r or equivalent), transmission over usb.

It's an interesting idea, but part of the problem is slicing is currently a tricky operation. I change settings based on a variety of things. I'm not certain what this is cutting out, cause I doubt they made their own slicer. If this is just taking pre-sliced data files, then you have to run everything through your slicer before you can send it to CUPS anyways. If they are integrating a slicer into CUPS, that'd be interesting, but I'd be really interested to see how they handle the many many settings that you can(need) to configure to get your slicer to output a file that the printer will work with.

Another issue is quality of progress display. I like to be able to see the print while it's printing, and track variables like temp of the printhead and progress through the print. Bear in mind, the average hobbyist 3d printer is going to take more then a couple hours to print anything of halfway decent size, so "oh you can just sit and watch it" isn't an answer. I personally use OctoPrint, which lets me track the print, and even see it using a webcam.

It doesn't matter, they'll burn most of it up, raise another round and pivot into a B2B client-customer IM app with patented business emoji or something.

No lessons will be learned, nobody will understand physics more because the things they (re)learned about basic science will be lost behind the veil of "stealth mode" and all of society will be a bit poorer in the end.

It doesn't matter because the money will vaporize, nobody will learn anything and we'll get another useless app that nobody will use (unless they do then they'll be lauded for great execution and their investors will be called visionaries, the pivot from ear shattering charge-tech to chat app will be just a footnote in everybody's success story).

Then the whole thing will be acquired by IBM or something and will disappear into history.
The batching that Disney is doing is a very recent direction and not something that is common - PBRT serves as a straight forward reference implementation.

You are right though that it would be fascinating to see the speed difference. My guess is that it would be substantial.

Even compiling PBRT with Intel C++ instead of Microsoft's C++ compiler gives a %30 - %50 speedup, likely due to reordering instructions for better memory coherency on a granular level (batching rays would give better memory coherency on a very broad level).

Flat files are very fast. The OS caches the files most of the time in memory. OS caching only becomes a problem when the hot data exceeds the memory.

By the nature of HN, there isn't that much hot data. Only the couple dozens of links in the HN front page are popular. May be couple hundreds or couple thousands people actively voting. All those don't take too much space and can fit in memory comfortably so the entire data set can be operated inside memory essentially.

The front page has 30 articles. Assuming 100k per one yields 3MB. It has about 1000 vote points. Assuming 50 bytes per vote, it's about 50k. So you can fit the entire front page data in under 4MB. That's tiny amount of data to work with.

meh, the only similarities between 3d printers and "normal" printers is the word printer in the name and the fact that they are output devices. 3d printers have much more in common with 3 axis CNC machines then with printers. In fact, the control code that many hobbyist 3d printers use is actually based on the control code used by CNC machines.
I agree with you completely. While I'm not totally on board with what the NIH is described as doing, what you say is not against what the parent said. The issue is that new bods are very likely to have a lot more useful year left, which counts in the equations.

Let's say the NIH values a year of life at X. There is a 90 year old and a 10 year old who need the same treatment that costs 10X. We should be much more willing to give the treatment to the 10 year old because he has a much better chance of 'earning back the investment', whereas statistically, the 90 year old is overwhelmingly likely to die in the next 10 years.
I mostly disagree although I understand and appreciate the sentiment of your post.

You have to consider first of all that we're working with scarce resources. When we're not, it's not even an issue to compare two lives if you can save them both. But in the case that there are limited resources and you happen to have to choose between focusing on two different groups of people and make that tradeoff, you inevitably have to base your decision on something.

Now if you have a 15 year old kid and an 80 year old person, and both are dying from some preventable disease at a rate of 1% per year, and you have a scarce budget to focus on researching one particular disease, which one do you choose to focus on?

Well flipping a coin is probably shit. But making a ranking based on qualify adjusted life years[0] probably makes more sense. Of course it's not perfect, but it's not beyond offensive if you ask me to go about reasoning like this to partially inform policy decisions.

Some of them are natural islands that have been artificially expanded to support a military presence.

The 12 NM territorial limit for a natural island certainly allows the power owning it to build barracks, airfields, and artillery batteries within that limit. And that prevents other countries from claiming or disputing the island.

$vqt is an exchange traded product that does a kind of dynamic hedge fund replication aimed to get better Sharpe ratio first and returns second.

It doesn't work because the rules are fixed but the market is changing. The model is tuned with a handful of coefficients and you could keep it going a while just updating those coefficients. Now so many vol products are on the market, the dynamics are entirely different.

Anyway buying vol is like selling short. Once in a while you get a good trade, but usually you are wrong because vol correlates like -0.7 with beta, and with the money you spend on the hedge you might as well buy more beta.
I grew up with people having natural colored teeth. People with artificial teeth color were those with false teeth. I find myself gradually getting used to it, but initially it did look like these people had quite serious dental problems: a problem bad enough to require all their teeth be replaced by artificial dentures. This is not attractive.

I have the same reaction to perfectly straight teeth or teeth without canines. It looks like false teeth. Crooked teeth isn't a good look either, of course, but forcing out all natural variation just looks like someone's had a problem. Uncanny valley: like someone with a synthetic flesh on their artificial hand.

I am interested in what is going to happen to the housing market. These systems typically have a 20 year contract. If the house is sold before that, then the purchaser has to assume the contract and the solar system. Those contracts could be extremely undesirable if the energy rates change a lot, better panels come out, financing/subsidies differs, it is better to use solar for hot water instead of electricity, battery storage turns out better, or a whole host of other scenarios.

If you were looking to buy a house, and it was 7 years into a 20 year solar contract (hence locking in the rates/financing of 7 years ago), wouldn't you want it either removed so you can put in something better, or be compensated for taking on such obligations?

I can't find out how often houses are sold in California, but it seems like ~7 years is normal.
I have to say that I find the whole concept of treason weird and outdated. Especially for civilians.
OK, but if someone who made a fortune in Germany moves to Switzerland and buys a Mercedes, does that not add about $50 K to Swiss GDP? The reasons I suspect it might are (1) GDP is essentially a measure of economic activity, i.e., transactions, and (2) how all of the small tax shelters, Monaco, Lichtenstein, etc, have very high per-capita GDP.

Regarding (1), it is possible that living in a tax shelter gives residents without a fortune more opportunities to make money than living in a country like Germany or the US does, but I lean towards the possibility that per-capita GDP is simply inaccurate or flawed as measure of the economic prospects of the residents who don't have fortunes.

Also, Singapore's per-capita GDP is very high compared to the personal income of its human residents (I have read) and I figure that was because a large fraction of Singapore's businesses are owned by non-Singaporeans (which has been the case, BTW, since Singapore's founding by British trading interests).
