What kind of crisis are you thinking? Because if you're talking something like 2008 again, dividend stocks should be fine -- the market value of the stock will drop, but the dividends should remain stable. In fact, the smart investor loves those times -- it's a great time to accumulate assets.

If you're talking something like a collapse of the entire economy, then yes, tangible assets like gold and real estate are much better. It's not impossible, but I don't know if it's especially likely that's going to happen....

That said, I do invest in gold/silver and real estate as well for various reasons. I also invest in dividend stocks for other various reasons. They all have a place in my strategy.

I haven't done much research on emerging markets, but isn't that a very high-risk/high-reward investment? For now, while I'm still stuck at my job and not yet "rich" (by my conservative definition) I'd rather mitigate my risk and have some control over my investments -- I plan to be successful and well-off, I'm not just hoping that I get lucky and one of my investments' value goes through the roof.

(I'm not criticizing and I didn't downvote you. I'm actually interested to hear others' investing strategies, maybe I can learn something new!)

I worked hard to get onto the front page of google for "email to google drive", and I have a few links from other places that drive a bit of traffic.

I experimented with adwords and stumbleupon but nothing caused enough conversions to be worth it. Every now and then I turn adwords back on to play with keywords a bit, but it's just not worth it at the low price point.

This title made me think, "wow, the Tor team is usually pretty on-the-ball, did they really write a sentence that started with 'Black Hat researchers', as if that was a thing?"

It's a truly bad title; it editorializes, it's contradicted by the article ("maybe" is not "affirmatively"), and it confuses its subjects with the venue they happen to present at (think about how nonsensical "ACM researchers do X" or "USENIX researchers do Y" sounds).
The link to my data visualization was on front page for ~8 hours. I got 10K hits first day, 2500 second day, 400 third day. The post was not specifically pimping my side project, but was a visualization of Seed Funding. That being said we had about 500 people from HN request beta access.

link: https://www.machete.io/board/view/seed_db_funding_rounds/157...

If you want to track visits from HN, MAKE SURE YOU ENABLE HTTPS BY DEFAULT AND LINK TO AN HTTPS LINK. It is in the http spec that no referrer info is passes from an https site (like HN) to an http site.

One last bit - we are hosted on a small Azure instance, we used loader.io to test what kind of a load we could handle and it shit out pretty quickly. We implemented some output caching and it handled the HN flood just fine (200-300 concurrent users).

I created http://jscompress.com/ several years ago as a simple online JavaScript compression tool that can also combine multiple files into a single output (and guarantees they will be compressed in the order input).

It's been making around $200-300 per month for several years, and this year has jumped up to $300-500 per month. This is only from Google Adsense: http://cl.ly/WobJ - I also always get a nice holiday spike in traffic and revenues, even though there is nothing seasonal about compressing some JavaScript.

It's zero maintenance, and sometimes I even forget about it. I spend maybe 1-2 hours updating the website to a new Uglify.js version per year. It's a simple single file node.js app hosted for free on Heroku.
Hmm, it seems to be written in TypeScript, but the source is only provided in JavaScript.
Been on the frontpage a few times, mostly weekends. 2/3 days got me 30,000 to 60,000 hits/day (24h) per time. My website is static, optimized and hosted on a cluster of geo-spread nodes so they were still doing nothing, the statistics server (piwik) did have a load of 4 at peak...

I have not done any marketing and my friends like to use it so its fun.
I take issue with the presenting of this.

The prime itself is kind of useless. What is useful is the number, plus the instructions about what to do with it, how to run it, how to apply it.

This is similar to saying "Book is just a collection of letters, but you can distribute the actual letters one by one and it's allright, isn't copyright absurd?".
I knew that Chiang Mai would've been there surely.
The argument that "it's just numbers" was considered insipid 20 years ago. There's a Dilbert where Wally says "I was just transmitting 1s and 0s, it's your computer that is really at fault for encoding them into <whatever the thing that got him into trouble with HR>." We are, of course, not meant to take Wally's argument seriously.

I could encode my inciting of a mob to violence as a prime number. No one, least of all HN, should accept this argument that "it's just a number."

If NFC ever takes off as a must-have in the payments world, I'm sure Square would try to use the NFC in phones through their app.

But given that they've already tried a "Just use the app, forget your wallet" approach that didn't take off like they wanted, I'm guessing they're not ready to try anything outside of mainstream payment cards.
I suppose so. However I don't think many people are really going to try that one, especially given the US Govt, while perhaps lenient on the DeCSS prime, would probably not be quite so lenient on a child porn prime. It's also just against basic human morality, really.
25k users is amazing. With a premium plan you should be able to convert that into excellent revenue. I suspect getting on CNet, Lifehacker and PCWorld helped a lot there - mind sharing how you got published in those places?

The site is a bit lacking in documentation (typical side project issue). It's $3/m or $30/year. I get a good mix of both types of subscriptions. I figure the price is low enough that it's not a barrier to entry for the majority of people. I also need to document better what premium accounts get you (ability to upload to different folders, etc).
I worked remote. In Canada at least they had no problem with me working on a tourist visa provided I wasn't doing any direct business in Canada - i.e. couldn't get hired, couldn't work out of a clients office etc. I had a 10-15 minute interview about it at customs, I was completely honest, and they were fine with it. As an Irish national I was allowed 6 months there just from filling in a form when I landed.

3 Ways to Engage Mobile Users this Summer
Right, and that's what is interesting about the OP.

They found a piece of information that is notable in its own right (by being one of the larger primes discovered through a particular algorithm). This single piece of information, without any further interpretation, can executed in order to perform the illegal DeCSS operation. IOW, somebody tells you that it's the Nth largest number proven prime by {mumble], and you copy that number out of the math book into an executable file, run it, and you're a criminal.

Sad to see the word 'hackathon' being misappropriated by a bunch of companies seeking people to test their API's and maybe inspire a bit of new business developments for free.

OpenState.eu is as far as I understood part of this, which I find even sadder since nothing about this concept comes near their goals as stated on their site:

"Open State represents a community of developers and re-users of open data. We work on the basis of a number of open data programs around political transparency, education, culture and health care. Therefore we influence policy in the field of digital transparency, open government and freedom of PSI and data collected by the (semi) public sector."

Please stop using the word hackathon for a lame attempt at sharecropping people.
It's reductionist nonsense, just as much as it's nonsense to say that certain weapons are an "illegal arrangement of atoms" or poisoning someone is an "illegal sequence of chemical reactions" or weaponized anthrax is an "illegal sequence of DNA."

NB: I'm not in favor of making certain kinds of encryption illegal, or DeCSS like tools. I'm also not in favor of making the meat-space equivalent, burglars' tools, illegal. There's nothing special about numbers.
This is good info, the only things I would add here:

* carbohydrate intake should really depend on your activity level. I'm guessing the majority of the people in these studies were sedentary so a ketogenic diet is a pretty good option. People who are more active should consume some carbohydrates because glycogen depletion tends to mess with energy levels.

* A higher dietary protein intake has been shown to increase satiety and lead to weight loss by itself. Regardless of your diet you should increase your intake of high protein foods; beans and low fat cultured dairy are good sources.
This comment will probably get overlooked, but how do you get into the "digital nomad" lifestyle? Basically, what kind of work allows you operate 100% remotely? Thanks.
Only if you could do that by some meaningful and simple process. If you simply generate a table (of the same length as the source code) that produces the source code when added to the bible, that's just basic cryptography, a sort of indirect way to store the source code.
Mori also provides clojure like functionality for the new collections greatly simplifying how you would use them - if you don't use Clojure you might think of the additional functions as an underscore for immutable collections.

I don't see a reason to use any other immutable js lib when Mori exists.
If you'll notice, there's no guarantee that it will be grammatically correct. There's just some statistical likelihood that it will be.

I built an information website (not USA) that now pulls in roughly $8800 a month via adsense. To get to that figure takes about 500k user sessions/month (lots of long tail traffic). Runs on a single medium website instance in Azure, takes about an hour a day in maintenance and monitoring for malicious traffic like scraping that can be a problem for info sites (I've mostly automated this).

The initial time outlay was quite large, but it was always approached from the point of view of generating a lot traffic to get the payback.

You're right, the "it's just a number" argument doesn't hold up. What's interesting in this case though, is that it's not just any other number, but a prime of mathematical relevance.
NFC (specifically PayPass, PayWave & Interac Flash) is becoming fairly ubiquitous in Canada.
The thing about the illegal prime wasn't so much that it's "just a number", rather that it would be archived and published independently because it's a novel prime for mathematical value, not for the purpose of breaking DRM, hence providing an interesting test to free speech law (can you really say that a specific prime cannot be published in a list of primes simply because it happens to represent DeCSS's source code?)
I'm not sure if its a good idea to share the exact topics, but generally they are language learning and software training (for example, specific CMSs).

I do everything through my own sites and find customers through via free podcasts, free and promoted youtube videos, etc. Udemy's on my list, but I believe in always owning your own brand, customers and leads.
My total hits on / of when PDFy hit the frontpage (https://news.ycombinator.com/item?id=8034431), and remained there for some 24 hours, iirc:

That said, the Hacker News post led to a bunch of other places writing about it a day or so later, the most notable of which was Gigazine:

If I recall correctly, my HTTPd was hit with some 50-100 reqs/sec total (for static + dynamic). It didn't really have any issues with it, despite running on a cheap VPS with 512MB of RAM, on a non-optimal stack (lighttpd + PHP + MySQL).

I've noticed a significant increase of recurring traffic since (it still hovers at about 5-15GB of traffic a day as opposed to the 2GB before, and there's a steady stream of uploads).

As long as you don't run something obscenely heavy like WordPress or Joomla, and you don't use Apache, you'll probably be fine.

The API serves nearly 1 billion calls per month, with lots of variations and spikes. That, combined with my lackluster ops skills, makes AppEngine's autoscaling a perfect fit for my use case and skill-level.

Yes, it's probably more expensive than if I used EC2, but I've never been awoken in the middle of the night to need to reboot a server, troubleshoot a memory issue, or scale up my instances.

The way he describes linking/including .c files is identical to how you can link-in/include assembly code via .s files. I don't see the latter going away (the standard `math` package uses this extensively), so why should the former---even if Go 1.4 or later itself doesn't use it..

As an OpenPandora backer back in the day, I can totally vouch for the problems the project had from their Asian parts manufactures. In fact, I think just about everything can be attributed to sourcing their parts in Asia. I think they later moved some aspects of production to Texas or something, but at that point it was too late.

I can also totally understand the position they were in. My understanding is the vast majority of parts manufactures are over there, and surely all the cheap ones. The Pandora was already going to cost over $300 USD, and I remember the project was taking on some of the costs themselves when reality didn't match with their projections. If they had any hope of getting it out the door at a price that people would willingly pay, you have to take on some risks.

Care to explain how and why the fraud rate went up?

Chip and PIN cards are widely deployed here in Spain, and all cases of fraud around me involved drunk people not covering the keypad when entering their PIN. In ATMs there's a nice animation of a hand covering the number pad, but not on POS (LCD displays just say "Enter your PIN"), and many people are careless or forget to do so.

I used to hear more cases of CC fraud back when magnetic strips were used, but I might just be biased.
The complex relationship between humans and data
Note that this wasn't due to trouble with calculating groundspeed, it just turned out that figuring out where a bomb would hit requires way more than just altitude, groundspeed, and position. Still, the fact that it's complicated is quite relevant here, especially since the bomb was dropped with a parachute. Somewhat counterintuitively, bombing accuracy was a pretty big driver behind a lot of the nuclear arms race, and improving accuracy is why bombs increased in power rapidly up to the 60s, then gradually declined.
This is great! Request - could you add the ability to choose your city and normalize the others? Example, I live in NYC, and I want to consider a move, how much cheaper is it? So if NYC cost is normalized to 1, then I can quickly understand the relationship to other places.
"Fail Safe" [1] is also an excellent movie. I believe it was based on the same book as Strangelove, but is a drama and not a dark comedy. Excellent movie and cast.
I'm not an expert on this area but I believe NFC smartphones can't currently act as payment terminals because PCI rules mandate that such things should be self-contained single-purpose devices with their own PIN pad.

However, the game could change completely with the move to tokenization.

That's really cool that contactless is so ubiquitous in Oz. As a nation you guys are very much ahead of the game on the whole contactless/NFC thing.
Excellent point. If you have a sphere that can maintain 2000C and melt through rock, toss it into a steam turbine and hook it up to the grid.

> You aren’t a lawyer, and clearly don’t have (much) practical experience as a foreign worker, and yet you still give out legal advice.

Ah hate to pull this card, but I've been an expat now for almost 14 years :) worked in Japan and Singapore (legally, with correct working visa etc etc), and just for this last year I've been a nomad flitting from country to country.

You mention "some countries" - sure some are stricter than others, but are any of the countries you're talking about on this list?

It would be insane for a country in Asia (except the ones still developing) to have such requirements. It is entirely routine for folks from companies in (for example) Singapore, to travel regionally for business on an extremely frequent basis.

I normally frown upon making assumptions of people :) but since you assumed I didn't have much practical experience as a foreign worker, I'm going to also assume you haven't done much business in Southeast Asia.

Berlin has a debt of over 60 billion euros, with an annual budget of 20 billion, 5.5 of which comes from the other laenders. This is huge, the other laenders have complained multiple times that they need to cut costs. Its GDP is 80 billion, compared to frankfurt (70 billion) or munich (60 billion) it's nothing as its a much bigger city. Berlin doesn't have a financial sector or any major industry really. Population has stayed (more or less) the same for the last 60 years.

Yes Berlin looks amazing considering ww2 & cold war, but is nowhere near the major european capital it should be.

Also, London today from London 2 decades ago is very different, a simple example is canary wharf that didn't have a single sky scraper 23 years ago.
