This is an absolutely magical and intuitive (not to mention beautiful) way to imagine the complex mathematical concept of a Markov Chain. This is the exact sort of pedagogical tools that MOOCs and other educational software platforms need to build and adopt to bring education into the 21st Century and finally replace traditional teaching methods. How does this compare to what even the best teacher could draw on a whiteboard? Teachers will still play an essential role in the emotional and social development of students, and they can then focus their energy on these things which software probably will struggle to ever replace.
I love the idea.

I notice that the only factors used don't seem to mention any political unrest. For example, the top rated city seems to be in Thailand... which has experienced a lot of political unrest recently: http://en.wikipedia.org/wiki/Thailand#2013.E2.80.932014_poli...
It misses Bangalore, India. You could live a good life for $750.00 a month. For an additional $35 a month, you can get a 60MBps internet connection. Weather is pretty pleasant throughout the year. You could sample quite an assortment of cuisines too. Meetups are fairly active as well.
Negatives: Traffic is terrible, but I stay indoors most of the time. Vendors do not speak English, but the number of non-Indians is high and the one can speak in English in any mid-sized shop.
Disclaimer: I am an Indian, but am not a native of Bangalore. I was initially resentful of having to stay in Bangalore, but of late have started liking the city.
Good webapp, that! You're doing something right!

Network effects always start with a small, dense network. Do you have a tight group of software developer friends? Have them sign up, share, talk to their bosses about hiring other developers. When hiring managers see that devs are there, they'll follow.
They don't currently but they will have to display ads eventually like Twitter, Facebook, Pinterest, Tumbler, and the like because a business can't run on VC fumes forever with stockholders.
Wait until you earn $2000, and then talk to an accountant, who will explain the tax stuff. Forget about patents and trademarks. Good luck!
They may have a chance of becoming a useful communication platform, but at $10bn, there's not a huge amount of upside left. I'm struggling to see how the very substantial risk of not becoming that platform could have been priced into the investment.
Wrote a basic strategy to sell call spreads and put spreads on various index ETFs. I only sell near-dated stuff <1 week expirations to avoid paying too much theta. A fairly consistent trading strategy can easily gross >50% returns on your capital. Not exactly "passive" - but with enough tweaks to the strategy you can get this to run with fairly minimal input time.
Note that you can have cheap equality detection by using e.g. flags or revision counters and so on (but there are limits due to JavaScript's nature..). The problem is that JavaScript currently doesn't support this properly out of the box, but Object.observe is coming in the next standard.

I personally like the safety benefits of immutability. You can give objects to functions and not worry about the functions changing the object. The only way to guarantee that otherwise is to clone the object, but that takes quite a bit of performance.
You start at 50% then it increases by 1% for each $2500 you earn. You continue building up like this until you reach 70%.

The interesting thing is that you can't control the price of your theme and it is set at the time of publishing by TF. Price range for WP themes is $35 - $50
"There is a big difference between the loss of 3000 people due to a deliberate attack on your country and the loss of 300,000 people due to heart attacks."

Since you obviously don't mean the heart attacks are worse, and we obviously don't agree, please support this rather than just asserting it. If it simplifies matters, first support that losing one person to deliberate attack is significantly worse than losing one person to illness. Then we can look at whether "significant" is significant enough.

One thing we can quickly agree on is that deterrence (or lack thereof) is more relevant in the case of an attack. But deterrence is only one kind of prevention. I don't see that the actual badness is greater in the case of the attack-caused death.

I definitely want to get around to doing work in Udemy, but I do have to say that they're not as big as, say, Youtube. :) For example, if you have a popular video, that gets embedded and linked to a lot. That builds link juice to your Youtube channel page and main site if write your video descriptions right, then suddenly you are ranking in Google search faster than you would normally. Same for a podcast and episode summaries. Having position and your own users in one channel also lets you ratchet up another by launching to those users. Over time, you build up big lists of people who you can re-launch updates or work with to develop new courses and products. Some people also use the leads to do affiliate marketing, but I personally prefer not to.

Anyway, owning your own traffic and lead list gives you the ability and permission to do that, so it's my approach.

btw, I forgot to mention I do have some free iOS apps to drive free users too. That by itself accounts for maybe 20% of my leads. I haven't touched Android yet.
Testing about a year ago. Had a 8x increase in CTR without much drop in CPC, so that was a big win for the site. I think there's more to squeeze out but it was written a long time ago in hobbled-together .asp, and that's not my forte. Someday I'll move it to a different back-end so I can experiment with things with more ease. For instance, I have content (with real words!) ready to go, but sadly the amount of work I'd need to do to hack the code to display it isn't worth it if I plan on changing the code out anytime soon.
What you wrote sounds to me like this: if SnapChat were something else, and not (just?) SnapChat, maybe in the same "space", it could be worth a lot.

Edit: I am deeply skeptical that a market filled primarily with people who have little or no income will support an ad-based revenue stream valued at $10bn. I would be even more skeptical if the revenue for SnapChat were supposed to come from a pricing structure.

We can complain all we want, but I struggle to see how we can place meaningful pressure on publishers.

I wanted to say that it's like iTunes and the switch to non-DRM, but I think the dynamic is different with Amazon as there isn't any meaningful competition on the e-reader device market as there was (and is) on the MP3 player market, where DRM was a major pain and thus a driver for DRM-free.

Short of Amazon pressuring publishers to drop DRM (which could well happen, but there's not a lot of business upside to it, although do downside either), I guess it will take a viable competitor to the Kindle that Amazon can't or won't provide an app for for DRM to get pressured out by end user market force.
Thanks for the advice. I think I'm going to hold off on actually making a service and consider doing something like Kickstarter. I want to see if I can get some funds to put together a better product and get a sense of the market / interest level.

Are there any protective steps I should take before doing that? I mean stuff like licenses / patents / trademarks / company formation etc.

Ask HN: New device, webapp and API to track your stuff, input appreciated
I've been working the last few months to create a easy to use low cost device for personal tracking called StowAware (https://stowaware.com) and just started shipping orders. The basic idea is a black box that you put in your car, scooter, shipment, backpack, or anywhere else you can make it fit and track its location for a year without recharging. I tried to build something that I would want to use and added features that seemed obvious like API/webhook access (with actual documentation at http://code.stowaware.com), controllable public sharing, on-demand lookups, https only access, turbo mode and an easy to use interface.

As a note of criticism, that video did not add to your post (it seems more like an ad for Stripe than an explanation video for your integration with Stripe), and the "humor" nearly made me close the tab.
We are still building the platform and inviting early adopters. We are a team of designers & developers and wants to solve the pain of giving away 50% of our sales on envato marketplaces.

I think it is because primes are widely accepted as remarkable. They are seen as things you discover - you don't invent them.

The fact that they have practical application is important too. Do we really want a legal system where you have to get clearances from the MPAA to make ship building software, for instance?
OP here, the post is only a simple trick that may be of some use to some people.

Eventually we merged that logic in an in-house app we built back in the days when the containers orchestration tools were still "rare", if i recall https://github.com/toscanini/maestro had just launched but wasn't really usable yet...

The only way to build a network is to start with a network. Here's a trick that's worked for me: Arrange with a conference organizer to connect people who are already there. After all, you know that these folks want to talk. once you have that critical seed, everything else will follow. Just make sure that your first users get real value out of your app!

I looked at rightjoin.io and the design is beautiful! Best of luck.
Please “steal” my idea
The feature set is comparable sans yet to come SortedSet and SortedMap (aka Red Black Tree). Performance should also be comparable if not slightly faster than mori in some iteration cases, as it's tuned for JS instead of ClojureScript and I've forgone some of the functional purity for speed. But this is anecdotal and I don't have any perf tests yet.
It should be factored in. But at the same time, screaming about the badness makes that worse. Refuse to be terrorized.
> It is happening for me right now

Yes, but for 90+% of the working population it is not happening right now, nor real soon.

> The "giant office" model is one that some companies still pursue

For values of "some" approaching "vast majority".

It's great that some people are able to work remotely now, and more will be able to do later. It will help the environment and generally be a good thing. But in most companies in most industries, this will not happen any time soon. It just isn't happening. Neither the hippest everything-aaS startups nor the most staid dinosaurs are eschewing coming into a common office en masse. There's no inflection point. Internet connections are faster and more reliable than ever, but so are the traffic jams at rush hour.

We've had more adoption rolling out whole new models of housing with 2.0 "walkable" suburbs than with working remotely.
I was thinking San Francisco, that sounds about for the bay area too.
HawtIO on JBoss Wildfly 8.1 – step by step
The SIM card is a full featured computer. It has memory, a CPU, and your telco operator can upload java applets to it which can interact with the baseband and the application processors.

And that's the point ... right now the stingrays and such simply act as IMSI catchers, etc., but if they can impersonate the carrier they can upload arbitrary java applets to the SIM card which can undermine the call-encryption app you are using. It's an obvious next step which you aren't protected against.[1]

I don't know if any SIM cards get DMA access the way some baseband processors (not all) do ...

[1] You could get one of those little sim wrapper foils and enable encryption-only for your SIM (which it almost certainly does not have now) which I think would defeat a lot of the carrier-impersonation attacks ...

"but how does ____ make money?"

Given how many times I've seen this in the last few years it might be time for me to figure out how to cash out before the lights go off.
Sure! I am probably biased, but I have been following Artemy and his studio from the early 2000s. He publishes semi-random notes on design, some of them influenced by realities of a post-Soviet state. Here is a link to the book: http://www.artlebedev.com/mandership/

Yes, it's from single theme. I'm currently at the highest rate of 70%.

There are a couple of high-selling authors on TF that established their theme clubs. They build up customer base using TF and then invite people to subscribe for a yearly fee to get access to all of their themes plus the ones to be released. I guess after you reach certain amount of customers such model is much more profitable.

Eg. http://www.themezilla.com/ and here's a link to their TF profile http://themeforest.net/user/OrmanClark

Wow! That's an amazing set of data! But as I watched the introductory video, a phrase caught my ear: "you can display this on NOAA Science on a Sphere or other spherical displays". Whaaaa? Spherical displays? And that was a throwaway phrase, like everyone has them. Here's what she was talking about, probably worthy of its own HN post: http://sos.noaa.gov/What_is_SOS/index.html
> Also, you don't have to control both ends. You just have to observe a given percentage of the traffic along its path(s), and you can determine a probability of which hosts lead to/from what traffic. If you're just trying to trace an unknown adversary, it may be able to [at the very least] identify the network they're on.

Really? I figured the number of hops involved meant as long as they couldn't control both Entry Guard & Exit Node you were relatively safe.

> The most effective way to mask the effects of passive statistical analysis is to employ either a masking effect or a countermeasure. Either make all the traffic look identical (and have its rate be identical and constant), or make all the traffic look random, insofar as garbage is injected or frames are truncated at every hop.

So, setup a webcrawler whenever you aren't using it that randomly crawls pages I suppose. Random garbage would make you easier to find, I suspect, since it doesn't fit with a "normal" pattern of any kind.

I mostly look at Tor out of curiosity. :)
> How is your experience with the reliability? I was recently up in Edmonton and anecdotally it seemed like people had serious issues with the NFC payment methods. Several times I saw people attempt to pay via NFC, try 5 times, then eventually pay via insertion+PIN. Looked profoundly frustrating.

Here (Austria) that's mostly because some people have cards without PayPass and they are not aware that they need new cards for it. I never had problems with it and always use it (even for transactions > 25 EUR) in which case it prompts for the PIN. It's super convenient and much faster.
I've seen (and supported) some dental software, and you're missing a detail: since your tooth-pulling coder is so solidly entrenched, no development beyond OS updates and imaging interfaces ever takes place. Therefore everyone suffers through mid-90s-era GUIs (and not the cutting edge from that time by any means!) until the dentists are all replaced by robots.
fyi - i can't downvote. not enough karma or something. /shrug

@mehmedrecip, You're basically right, but there's a modicum of luck in all these things. Anyway, I agree that rightjoin.io is beautifully designed.

I checked out the features and it looks like they know what they're doing. Good stuff, best of luck to them. The industry needs some new techniques.
Personally i would hardly consider Tampa and Orlando as Dixie. Slightly conservative? certainly. Though not Southern and more an odd mish-mash of liberal and conservative, mostly pro-development, but with an odd pro-environmental strain in the Tampa area. Gainesville, FL is an odd duck miniature city-state: half-Southern, half-hippie values, similar to Athens, GA.

It seems, we are seeing the repetition of the first tech bubble when it comes to overblown valuations. Those valuations aren't really on realistic future earning potentials anymore. They rather are on future expected selling price. The idea being that 'I buy something for 10 times as much as it is worth, in hopes that I find someone who will pay me 20 times as much as it is worth' etc. Obviously that can't go on forever and the bubble burst might be as dangerous and devastating as the first one, unless valuations magically cool down.
React immutability helpers pros:

- Work on regular JavaScript Object and Array so it's easy to get started and integrate to your app

- You don't need to wrap objects inside of Immutable to use it and you can use `obj.key` and `arr[0]` syntax for accessing them instead of `obj.get('key')` and `arr.get(0)`

cons:

- There are no safe-guards if you mutate the objects and it'll likely break your app in subtle ways. This kind of discipline is very hard to get in big projects

- You are stuck with primitive data structures (instead of map hash trie), so it's not going to be as performant and memory efficient.
The difference is that if you use Object.observe to track changes, then you don't have the ability to hold onto the previous version of an object and know what the old value was.

This is important for animations where you want to animate from the object's old value to the new value.
USPS has authority to run its own deficits quarter to quarter or year to year, and they have significantly improved their financial situation since the financial collapse and large drop in first class mail usage. Last year they would have run a surplus if it were not for the pre-funding liabilities: http://www.nytimes.com/2013/11/16/us/postal-service-trims-it... Congress needs to get out of the way and let the USPS succeed, but I fear the privatization interests are just setting them up for massive failure.
And to iterate a bit on my last point ... there are spaces where advertising is inherently valuable, where you have a captive or semi-captive audience ... I don't see messaging (at least in the mobile space) as particularly banner-friendly.

Now obviously I wish I knew how to target the mobile messaging market; I don't. But it seems like you could see mass migrations based almost exclusively on presentation the way MySpace rapidly lost to Facebook.
