I've found the simpler solution that works for me is to fast for 16 hours, including the entire flight, and eat breakfast on the plane an hour before landing. Also, I sleep on the plane, starting right after takeoff, with a sleeping pill if needed. This has worked for me in both directions for flights like Vancouver to London (9+ hours). Instead of being ruined for a week, I get essentially no jet lag.

Yes this means turning down all food and alcohol on the plane, and just drinking water.

The idea is that your body has 2 clocks, a food clock and a light clock, and that the food clock will win if you fast and then break your fast (get it?) with an appropriately timed breakfast.

Chris very cool. We have a golang driver for helium that will be opened up soon.

The bridges use multiple omnidirectional chip antenna per radio. Each radio also has a u.fl connector so you have choices. Hope to see you sign up for the beta. Would love to see this in action.
So... the idea would be I'd design, engineer and manufacture a (presumably hardware) product at great expense that's essentially 'locked-in' to a single proprietary network that could a) spontaneously cease to exist due to insolvency or such, b) increase my access costs arbitrarily or through acquisition or c) become detrimentally unreliable through poor scaling or other disruption, and I would have absolutely no recourse or ability to transfer my products over to another method of communication without initially building in such a 'fallback' (in anticipation of these potential pitfalls) at even greater expense?

No thanks. Great on paper, but bad in practice, no?
While I see the appeal, every time I have to zoom in, a part of me wishes there was a nicer stylesheet for mobile, HTML-be-damned. I suppose tables really were anti-responsive: before them text naturally flowed, after them, text generally flowed again. Of course... Design could still mess things up ;-)
They said "the goal should be to find a way for people to meet their basic needs without needing a job."

e.g., if someone has off-grid battery tech and solar (or whatever else), they can knock off their electricity and gas bills. If they can automate the recycling of sewage into clean water, fertiliser and leftovers, and they had water storage, they could ditch their water bill.

If they had underground (think shipping containers) and automated food production, they could cover some of their food bills and still have ground level land free for entertainment.

Of my general costs, I'm not immediately sure how we would ultimately replace council costs (roads, etc) and internet connectivity.
We have managed to create around 4000 jobs for audio transcribers. Around 10% are regulars on our platform. Long way to go for a million.

I actually dont see this as shameless as you title it :) however I still think the quickest for me to get an email out to my subscribers is to sort Mailchimp first
I'll check your product for future emails based on my Mailchimp experience (pretty bad so far..)
> Why do so many people here think this kind of thing is okay when Facebook does it? Is it simply because they feel kinship to a tech-related company?

Yup. It's like asking in a wolf forum if having the sheep for dinner is considered ethical.
This doesn't sound that unbelievable to me. You don't need a lot of power to send a receivable radio signal. (GPS is a good example, the satellites are 20,000km away and transmit at 25W, but GPS still works just fine!)

The basic equation is:

channel capacity in bits/second = bandwidth in Hz * log2(1 + signal power / noise power).

So let's say they are using 1MHz of spectrum (WiFi uses 20-80MHz), are transmitting at 1mW EIRP, and have an omnidirectional receiving antenna (there is no such thing, but "assume a spherical cow", it's the worst-case anyway). At the claimed range of 4 miles, the signal will lose 100dB because of "path loss" (actually spreading out), giving you ~ 1e-10mW (-10dBm) of signal at the antenna. Let's set the noise floor at -60dBm which I have not really measured, but sounds good. That's 1e-6mW. Plug this into our formula and you get a bitrate of about 1 bit every 7ms. That's ~20 bytes per second!

So let's say that we want to collect a sample once a second from 256 devices. We get 20 bytes per second, so can sample every 256 seconds (let's say that's 5 minutes). There are 256 devices, so each one gets a 1 byte ID. Then you have 19 bytes of payload, which is fine for things like thermometers or your FitBit or whatever. Fill the rest with an error-correction code.

Now you have 256 devices, each using 0.01W of power for 1/256 of the time. With a 5Wh cell-phone battery, that's enough for 14 years of transmissions.

Now, to get thousands of devices, you can use more spectrum; there is plenty more in the ISM band. You can transmit with more power, 0.01W is what a Raspberry Pi IO pin can transmit connected to a long wire. You can get a directional antenna, since you probably aren't listening for signals from the sky or underground. You can also send less data.

Anyway, I ran the numbers and I don't think this company is claiming to violate any laws of physics! It all sounds quite possible, actually, with the right engineering work. I'm looking quite forward to purchasing an eval board!
That's how most of the teams have been able to counter Messi so far; whenever he gets the ball, make sure two or three guys are on him. That he's still scored four goals despite that is a testament to his prodigious skill, but its certainly been effective at cutting that number down.

> I've never really understood why people get in this mindset of "X is my editor, and I will only use X."

If you use certain software a lot, you'd find it behaviour and shortcuts ingrained into your subconscious mind. Like driving: an experienced driver doesn't consciously think of how to control the car, she just does.

This is what makes Emacs or vi users so efficient: they had years to get the operation of those editors ingrained into their brains. Which takes quite an effort, that is not worth repeating with another editor (unless yours is broken).
years ago, probably also in nature, I read that the only certain thing that the studies found about vitamins was that it made for expensive urine.
MongoDB memory management demystified (presentation from MongoDB world 2014)
Why only 128 ASCII Characters? Just so the secrets are manageable? I think that restriction should be removed... It would keep it's primary use case and make possible others.
As asgard1024 mentioned, yes you can make the paper available on your own personal site. However personal websites have a lifespan - people move institutions, change jobs (e.g. in my case into industry), and eventually die. Thus the need for a repository of publications maintained by a third party.

ACM's digital library serves this role - and well (for those with access to it) - but the fact that copyright is already surrendered by the author prevents any other third-parties from building similar repositories. Given that doing so is relatively cheap and easy with the technology available today, I see substantial value in making it legally possible for this to be done; an example where this has been done is arxiv.org. These sites are basically the Internet equivalent of libraries, and are analogous to mirrors or repositories of open source software.

Having this ability means we won't lose the material just because the author is no longer willing or able to maintain their personal website.
There is also infinality fontconfig mod, which brings even more options and some sane pre-sets (it can even mimic Windows).
I was a member for a few years. I left when my role moved away from software development for few years.

I'm thinking of rejoining, there are some interesting articles [Edit this is incorect: and if you pay for the digital library you get Safari Online access too I think]. ACM seems much more interesting than the BCS which (from an outside prejudice perspective) feels even less relevant.

Edit: Looking at the site again I'm wrong and Safari Online access is extra. Not sure if I'm misremembering or it has changed. Given this I'm unlikely to rejoin.

Very interesting resource!
It's amazing to see how after 10 years of using command line that you can learn new tricks. Every single day!
Any ideas how the whole thing will be implemented. The site only contains very generic information about it.

How are the interviews going to be conducted ? What will be the different forms of interviews (as most companies have different forms and phases of interviews) ? How will the feedbacks be given ?

Hope this just doesn't turn out to be just meeting place for anonymous interviewers and interviewees .
That is a fair point, in fact a very fair point if this was part of some "reporting" thing, the text might have been embedded in the email itself.... (Which raises other questions though, like signing and encryption and storage etc)
Chikun-What? A New Mosquito-Borne Virus Lands In The U.S.
Ask HN: Can someone in SV/SF please hire me?
I moved to SV several months ago thinking that it wouldn't be too difficult to find a job. Yet here I am, after spending several months looking for a job, sending a few dozen resumes and after having a few interviews, with no job found and feeling quite hopeless.

All I wanted from the beginning was to work for a small startup, but what I learnt after having a couple of interviews, is that the hiring process seems to be quite different to what I was used to... For example, we rarely talked about my experience, the projects I have worked on or about samples of my work. It's just a few technical questions, and then the whiteboard; it's hard coding with just a couple of markers (I barely know how to do handwriting anymore!)... I guess I'm used to: syntax highlighting, code completion, documentation, etc. These tools might be making us not so good with just an old plain text editor, but as far as I know, we use them in the name of productivity (really, try a different context: go make popcorn without a microwave oven). If you don't know what you're getting into, you're going to fail and feel like a fool real quick, which will also be the case if you don't practice this kind of problems a lot, and/or you don't have all your CS and technical knowledge very fresh in your mind.

I'm running out of time, so I decided to write this plea for someone out there that could help; all I'm looking for is a humble job where I can do coding for a living. Right now, I'd say I'm better at doing iOS development, but I'm familiar with Android, JavaScript, and Python; I also know SQL, and the usual JSON, XML, HTML, CSS. Can someone please give me a chance? I really need something right away.

Thanks.
My goal as an entrepreneur is to eliminate a million jobs.

Surely your goal as an antrepreneur shoul dbe to provide a million people with a desirable new product/service/ The word 'entrepreneur' means 'between-taker', ie someone that carries things back and forth between suppliers and consumers, like historical traders.

Identifying economic inefficiency and finding something to remedy it is one way of identifying your target consumer, but far from the only one. In your example of the shipping container, you neglect to consider that they're only useful insofar as there is sufficient trading activity taking place to fill the containers up. Labor shortages aren't often a big limiting factor on trade.

I think it would be great for society if there were less jobs and people were able to pursue more creative endeavors than menial jobs.

So do I, but creativity and productivity are wholly different things, especially when it comes to paying the bills.
Yes, I proxy some of my work ssh connections so I can access them despite working from home.

Yes, when I'm working from the library, I proxy all my work ssh connections over a ssh connection to my personal vps, because the library seemingly blocks everything except dns/http/https; sshd on my personal vps listens on port 443 for this very reason.

Yes, at work we use CloudFlare to proxy our website.

I confused OpenCyc with Freebase, which was linking to OpenCyc at least in the past. I know Freebase got acquired, but thanks for the clarification! It's really nice that Google is aggregating a lot of AI power. Combined with the robotics companies they've acquired, too, the direction is clear.
Changes to Gmail's spam filtering algorithms, however, do happen without your consent or knowledge. Similar to how changes to the algorithm governing FB's News Feed happen without your consent or knowledge, but you know that it exists. Like your spam folder, you can tab to "Most Recent" to see what you are missing.
Presumably, this would mostly be a connection standard for devices that aren't owned by "people", per se.

In a true Internet of Things, the Things that matter aren't really consumer goods; they're the Things which make someone money or perform some civic function, and for which it isn't readily apparent when they stop working, unless someone notices and reports the failure. When these devices can report their own failure, they can be fixed much more quickly.

The most vivid (and banal) example of this is a paper towel dispenser in a washroom, which can report when it runs out of paper. Other examples include power/water meters (which already operate over 3G), transit card readers (also 3G), traffic lights and cameras, parking meters, etc.

It'd also be interesting to use it for drones, though. Anything that can save battery life better spent on flying would be great for that industry.
If anyone's grasping about for a mobile app idea, this article seems to be crying out for some kind of accompanying configurator. I loosely grasp what it's trying to say about the causes of phase shifts, but to apply it to my next trip I'd need to reread the article and spend some time in front of a spreadsheet..

I'm not sure why I got downvoted, but, really, back at those times, maybe out of great respect, but he was "Douglas". :)
I've sent you an email. I would like to talk about this some more, thanks for replying.
For what it's worth, Rayiner's comments make perfect sense to me and in context of the broader thread. I wonder if you've approached them with a preconceived intent or argument and, as such, read into them?
I'm commenting because I'm genuinely curious about the technology, I'm not trying to tear anything down.

That said, the technology page is not very clear.

The wording doesn't currently indicate this is idealized or limit conditions. Because you say it covers tens of thousands of devices over such a large area, I assumed this would be expected (like a cell tower). Your description actually fits very closely with a cell network. Why would a device that covers only my home need to support connections with tens of thousands of devices? Would it cover me and all my co-workers at the office 1 mile away (well within it's 4 mile range)? Or would I be expected to have a bridge at home and in the office? Is it like a Femtocell in a mall or like the ZigBee bridge sitting in my living room?

Given that picture, I'm genuinely curious about the capabilities. Immediately below that paragraph are bars that show a 700+ day battery life and a transmission power of 0.025mA. Are these for a totally different use case? If so, I'm confused. If not, it's amazing and I'm very exited. How is a transmission power of 0.025mA @ 915MHZ possible at a range of 4 miles? I would have assumed 1000x that (at least) would be necessary on unlicensed ZigBee spectrum. Similarly power would need to be amped up on the receive side,... meaning receive windows would be costly.
"Our first MAN is being rolled out in San Francisco" for a fraction of a second I thought this is a network created by men walking on streets with some form of connectivity gadgets. You know, like the ones holding signs on the pavement. I guess I am watching too much louis ck.
I would not like to use Uber as an example of creating jobs.

I see them as KFC in the egg farming world - pushing all the capital expenditure and risk onto smallest individuals whilst then aggregating what should be a distributed market.

I think any company capable of directly claiming to create one million jobs will be this abusive on a massive global scale - not something I would want to invest in personally.

I can imagine plenty of ways to create a million jobs - invent fusion power, invent a foldaway surgery theatre, but they are not things that capture the value back to the originator (that is the genuine use for patents).

So this seems like "build a market platform, make sure it is not interoperable, find a business model that makes individuals dependant on you, while pretending they are businesses". I think I understand what YC is reaching for here - there is a coming hollowing out of jobs, somehow we need to create new jobs. I agree - but a business model that creates new jobs and captures that surplus seems to me abusive - or it is a marketplace open to competition from other marketplaces and that's rarely a way to make money. So far.

Edit: clarify as much as I can this early before coffee
> Why in the world should that be assumed instead of checked?

Because email is not encrypted and not secure... so any server or anybody in between GS and the google server that data wound up on, could have a copy or seen a copy.

Not to mention all the possible ways this data could be exposed. The receiver took a picture. Printed it. Saved to a file. Forwarded it and it was forwarded again. Not every device marks emails as "read" on the server. The point is, Google can't tell GS if this data is secure or not. Deleting the email is irrelevant at this point.

You are forced to assume it has been exposed because the data left your premise and your control.
To further complicate things, you also have to count the _customers_ of the firm in question. Amazon made certain things cheaper, and there are probably at least a few marginal businesses out there that can exist because of it.

A similar argument goes for eBay -- there are probably entrepreneurs out there who make a living in part because they can use eBay to buy things. This includes obvious stuff like resellers, but also less obvious stuff like a business that just uses eBay products as one of many inputs.
I was immediately reminded of GATTACA, which looks more prescient by the day.
The approach is not entirely new. A company called Sunmachine in Germany built a similar device producing 3KW and fed by wood pellets made from saw dust - so even more carbon friendly. Sunmachine had to file for bankruptcy as it couldn't find the working capital to produce the neccessary machines it had in its order books to bridge the gap before getting paid after installation of the units. It was aimed at the residential property market.

1.) Yes. Almost always.

2.) I use ssh to the tunnelr.com proxy/vpn service. It's usually just a
socks5 proxy link bound to the internal interface or localhost. Using a
VPN service is very useful since I get a choice of exit nodes all over
the planet which really helps a lot when traveling. I do a simple hop
count (tracert) to a few physically close nodes and pick the closest
available node.

https://tunnelr.com

If you don't like using ssh, they also support IPSec, L2TP, PPTP,
OpenVPN, and plain old unencrypted SOCKS (4a/5).

3.) My only real choice for ISP is Verizon Wireless, a cellular phone
network, through an G3 (EVDO) or G4 (LTE) dongle. Verizon Wireless does
all sorts of strange mangling, shaping, and recompression on network
traffic (such as degrading images with higher compression ratios). The
reason why they do this is simple; they expect the end device to be a
smart phone, and it is in the vast majority cases, except for their
dongle based customers.

Thanks! I'm happy with my current job, but would love to play with your eval boards (in my copious spare time :) when they're available. Send me an email (jon@jrock.us) and I'll buy a couple to try when they're ready.

It's rare when I see a startup on HN where I initially think "this is impossible", but do a little math and find that it's actually quite possible. Easy? No. But you're going to have a much better time working with the laws of physics in your favor than you would if you came up with something theoretically impossible :)

In the interim, check out http://wsprnet.org/. There are lots of people on the forums that are interested in weak signal work. If you have (or get) a ham radio license, you can try sending WSPR from a raspberry pi with a long wire connected to an I/O pin. It's pretty cool! (I've been meaning to set this up at work to see if I can get the signal at home on various bands, especially VHF around 144MHz or 1.2GHz. If that works, I have no doubt that you guys will be successful. And I think it will work.)
To those of you downvoting the above post, thank you.

I've been influenced by jetlag more than once and I can say hands-down the most effective and least cumbersome method I've found is just to take a Melatonin pill and drowse off to sleep 10 minutes later. If I'm still feeling it, I'd take another one before going to sleep the next night.
