Last time I checked (5 years ago), small satellites were a _booming_ industry, but also a very amateur / research oriented one. While a professional military or communications organization may launch a number of small satellites, they tend to go through the same process as when they're building a large one. As such, most of the small sat world is focused on amateurs launching small satellites of their own design, student organizations and startups launching 1U type boxes, and research efforts for which a tiny box is sufficient.

As for your second question, a few points:

1) yes, it is massively cheaper to give your nation cell coverage via satellite as opposed to via tower. There have been a number of success stories in Africa where a local government / business managed to put together the funds to buy a communications satellite, and overnight, the entire country has cell phones.

2) No, you wouldn't do this via a small sat, you'd need a real deal communications satellite to achieve this. One of the key features of small sats is that they are small enough that if you beg and plead enough to the powers that be, you might find room on a launch vehicle to launch your tiny satellite in some spare room. If this service can open that up to people who don't have governmental / educational connections, all the better.

3) There is research on creating swarms of small satellites that can communicate and act like one giant one. That's pretty cool. I worked with these guys http://www.spacecraftresearch.com/blog/?page_id=260 for a time, and they were working on setting up satellites that were so small, they couldn't even fit a real antenna on them, but figuring out basically a radio based encoding pattern so that you could pull their signal out from beneath the noise floor anyway.

That all said, the industry is dominated that way because of the difficulty of launching a satellite to begin with. If you can make it easier to launch sats of any type, then people will start building those too. Build it, and they will come.

The Markov property is that you can model the system as being dependent on the immediately previous state + noise.

The lottery ignores the previous state and is defined purely by the noise, so it is a (trivial) markov process.

More complex systems depend on the entire history (e.g. to model a poker player you have to consider all of their actions up to the current). Newtonian systems are markov, if you know the state of the system you can run it forward in time deterministically. Even if your knowledge of the state of the Newtonian system is not fully known, you can still run the distribution of states forward in time precisely.

current_state = previous_state + process_noise

typically expressed in matrix math but the idea is as simple as that.

I think the tech industry discounts the value of expanding your horizons. I have a background in design and writing, and when I choose to incorporate those disciplines into what I do with code, a lot of magic happens. Let's say I order a class like a do a news article (upside down pyramid, aka most important shit first). Or I apply my own design eye to the motion or interactivity of a static design. Or even to how I interpret the structure of the code?

Reach out. Learn as much as you can. You end up finding a lot of relationships between a lot of things in life that can apply equally to each other. Right now I'm digging deep into car repair. It's fun to find the correlations between the component systems of a car and software.
This is certainly also the most important thing for existing PHP developers still hanging on to the "old" way of writing PHP code. Having worked on sites where everything is an undocumented mess of manual multi-level includes with shared globals and half-baked implementations of things which already exist, in a better form, well tested and documented elsewhere, I feel like I need to shout from the rooftops php has a package manager! f_ing use it! and url routers are a thing now!

It really is surpising how far you can get with a little effort now in PHP, and how much suffering you can avoid by just letting go (of what, admittedly, makes the language fun for some - it's raw, ugly, stupid simple quick-and-dirty hackability) and embracing structure. And open source code.
Well, one problem is that some people, including myself, object to assigning probabilities to facts of nature. What is the probability that the mass of the Higgs Boson is 126 GeV +- 0.1 GeV? That doesn't make sense, it is either 100% or 0%, true or false, as the mass is a natural constant. It's like asking for the probability that 3 is between 2 and 5.

Of course, you can make statements like P(m=126) sensible, by recognizing P as degree of belief, or plausibility. These don't describe facts, but rather knowledge, or your uncertainty. The wonderful thing is that they fulfill the same axioms as ordinary probabilities, and thus you can use Bayes theorem and so on with them.

Distinct from degrees of belief are probabilities (or frequencies in some Bayesian literature). These do not describe your uncertainty, but are really physical properties, or facts of reality, in disguise. If you have a fair die, P(1) = P(2) = ... = P(6) = 1/6, the equality of the numbers means that all faces have the same area (under the plausible assumption that the die has a uniform density). The area of a face is (for small deviations from P=1/6) proportional to the probability to land on that face. So a probability of P != 1/6 means you have a deviation from the perfect cube form.

One reason I think it is very important to be aware of this distinction is that people object to "Bayesianism" because most Bayesians don't make the distinction. People do not reject Bayesianism because it's methods don't work, they reject it because it seems philosophically unsound. If they would stop calling plausibilities probabilities, a lot of discussion and confusion would go away IMHO.

(Maybe we should forgo all the p words and call the Bayesian quantity just "awesome score" or something. Less people would have problems with evaluating an arbitrary formula that doesn't have all the philosophical and political connotations that probabilities have.)
Trying once and failing do not mean we should never try again, I thought it was well understood here.

The backwards compatibility argument is interesting. I think it's really compelling, but it's also worth taking into account the pains that the Haskell community has been feeling since standardizing the standard library as insufficiently generic.

I have no idea if a similar problem is possible with Rust, but it'll be interesting to see how HKTs enter the scene if and when they do.

Right now, SpaceX can (and does) have access to that limited market by selling off payload on current launches. It's cheaper to just bootstrap on to an existing flight than dedicating an entire rocket to a small mission. If and when the Falcon rockets become reusable, it's very difficult to imagine this series ever being competitive. SpaceX aims for launch costs of $5-7 million when they achieve reusability, putting the per-kilo cost somewhere between $540-700. At that price, these rockets will have to have a total cost of only $350k to match what SpaceX offers.

These people must either believe that SpaceX won't achieve reusability, or their rockets will. Maybe a combination of both?
Incorrect. Thanks to the ability of the US to project conventional force, they have deployed troops in Eastern Europe, the Baltic and the Black seas, thus stopping any further Russian aggression. This could only be done through a show of force that displays the ability and willingness to engage Russian forces should they try their tactics on a NATO state.

Furthemore, the US are keeping their side of the agreement. They are providing Ukraine with military equipment and intelligence and leading the way in destabilizing Putin's regime through sanctions. Thanks to that multi-levelled support and offensive Russia is right now losing the war in Ukraine and is on the brink of a Revolution itself.

All of this with barely any help from central Europe, which has its head up its ass and has succumbed to Russian influence and propaganda.
Chip and pin pretty much solves this. My understanding is that its much more difficult to intercept the transaction due to the cryptography involved. No one handles your card or walks away with it like in the US. They bring the wireless cc terminal to you.

These are coming to the US in 2015. I suspect a lot of the issues we have today will be minimized as we move away from magstripes and waiters walking away with your credit card.

>My cash has never been stolen. I have never been mugged.

If you can figure out how to make this scalable to everyone, there will be no advantage to carrying plastic. I have my doubts that this is possible.

>My card is far more likely to be skimmed or be stolen/copied in a massive database like Target than for my cash to be stolen.

Mine was, at Target, my account was drained of about $2K, and it cost me about six phone calls over two days. The only lingering effect was an example of how trivial an experience with false charges on your debit is, which comes in handy during my rants about how many politicians, news outlets, and credit card marketers scream about card number theft in order to grab eyeballs and push agendas.

I'm not a big advocate of slutting your card around, but that's because I don't feel like broadcasting every single minor purchase I make throughout the day, and because it's slower and more annoying (to you and everyone around you) than having your cash ready before you get to the register. I'm embarrassed if by some lapse of routine I get to the checkout and have to use a card for a $10 purchase, and the first thing I do is apologize.

Do you have any examples of awesome restaurants that have poor ratings on Yelp? Assuming a sufficient number of reviews, Yelp ratings are at least "directionally accurate". In my experience, a place with four stars is decent and two stars is poor.

Many Asian restaurants in the Bay Area that I like are 3 or 3.5 stars, though many others with that rating are mediocre. But on the low or high end, it seems very accurate.

Excellent topic.

It resembles something I've heard graphics designer do when they try to appreciate the information hierarchy or the contrast on a creation, without being disturbed by the meaning of words of symbolic value of graphical elements.
Although, I disagree about comments. I mostly overcomment code, because sometimes, a project lacks a proper specification and it's sometimes the only place where to explain what you actually do.
Likewise, we are running our SaaS product's backend with full C# -based stack (built from scratch without using any PaaS specific technologies for IPC/RPC etc.etc. so can be run on any provider) on top of Windows VMs, but database is running in Postgres. The licensing being one of the major reasons for that and avoiding SQL Server, even though it was a technology I had lot of experience from before when I was doing IT administration in MS environments. But Postgres is not that dissimilar, at least when you tend to do lots of operations in the code and not inside the DB as storprocs..

Our client/agent piece is also written fully in C# (we support only Windows workstations at the moment so it was no-brainer decision) and recently I have been looking into Xamarin to leverage that investment when moving into other client platforms.

This has worked great as I have a history purely in Microsoft technologies so the administration is lot less of a burden compared to trying to figure out everything for some other stack. If you are fluent in one technology, why not use it, right? And besides, with Mono there's at least theoretical path for running parts of the backend on Linux, but in the big picture the licensing costs for Windows vs. Linux in managed hosting is peanuts.

The tone of your comment is fawning and is easily confused with trolling, and "brave" is a word commonly used contrarily to indicate disdain for someone's actions. That, or you're actually just trolling.
NB the diagrams weren't legible in the Kindle version I paid for (some years ago; hopefully it's been updated). The diagrams were fine in the PDF version that I found somewhere.
They already do: Facebook and Google both have a "pages" feature which is designed for exactly that. Most businesses don't seem to want their Facebook/Google page to be their official website though, perhaps they think it looks unprofessional.
I've been told by a close friend who's an early Baby Boomer who's parents were therefore in the Greatest Generation that thoroughly experienced the Great Depression that there was a lot of social pressure against households with more than one job holder.

I think we can expect plenty more insane proposals as our current Great Recession grinds on and on. Fortunately our system of government is more responsive to the people, and we've got all these Petri dishes of states and cities that are trying out some of these bad ideas for object lessons, like e.g. Seattle and Michigan with elevated minimum wages.

On the other hand Obamacare is pushing vast numbers of hourly workers into < 30 hours per week for any single job ... so, really, we're already starting to do this to people with lower paid jobs :-(....

IIRC, the VentureStar was going to use a linear aerospike. With at least one combustion chamber on each side, it seems an easier design than a ring.

Their design seem to indicate they may want to pump air through the spike body to either cool it or as to use it as "bypass" volume in an inverted turbofan-like design. It's intriguing.
RakNet is pretty legit. It's very low level so it doesn't make making a networking multiplayer video game easy, but it does do a good job solving one critical component in doing so. Great move.

>I am not sure how ATM/check card fraud is handled.

In my personal experience, through a couple of phone calls. I can't imagine that credit card fraud could be any easier than the experience that I had with debit fraud.

edit: http://www.consumer.ftc.gov/articles/0213-lost-or-stolen-cre...

tl;dr:

1) Maximum liability is $50 if you report a loss or theft within 2 days of being aware of the loss or theft, $500 afterwards, until 60 days after you receive the statement with the disputed debits on it.

2) Whether or not your card was lost or stolen (or cloned), 60 days after you receive the statement with the disputed charges on it, your liability becomes unlimited.

summary: Report loss or theft within 2 days, check your statements for crap charges at least once every 2 months, and your maximum liability is $50.
I use a lot of terminal applications for mail, irc, music player, chat. Then there are always about 9 permanent terminals for generic local stuff such as setting up tunnels, man pages, socks proxy, a calculator, etc. Then I've got 9 terminals per remote location / project I'm working on. These are shells for file system navigation, grepping, reference, editor, a few database sessions, log file tailing. Then there are the random terminals opened for who knows what. I generally keep the terminals for projects I work on the most open all the time.

30 sounds like a lot, but really it's a very easy workflow process to follow if you've got virtual desktops. For instance, all persistent stuff (irc, music player, chat) lives on desktop 1. Mail, password manager, todo list on desktop 2. Browser on 3. Local terminals on 4. Remote terminals in tabs on 5, etc. I've been using the same workflow for years (going on decades). I can switch to nearly every window in two keystrokes, which never change.

I didn't write that sentence very well if that's how it was interpreted, sorry. I meant to say that the abstractions available to Haskell are more powerful.

I can't really think of any abstraction that's not available to it - even an Object System is possible in Haskell, it just wouldn't be as easy to use as Monads are.

Yeah, but with Squarespace you actually have to do the work of building and updating your web site. I'm proposing Google, for example, use a mix of algorithms and design to expand that "info box" you get when you search for Willy's Pizza or Suds Laundromat into a full site, and sell it as a turnkey solution.

"Here's your (crummy, last-updated-2011) web site today, and here's the beautiful one we've already built for you, including full online reservations and take out ordering. With just a few clicks you can customize it with photos or a new menu. Pay us $NN/month and we'll immediately switch your domain to point at this shiny new site."

Squarespace could move in this direction, too, by continuing to specialize and extend its templates until a good looking, functional site takes an average of minutes. But Google has the advantage of already knowing enough about the average small business to build it a better web site in literally milliseconds.
Cheap way to drive from Santa Clara to San Fran?

Wouldn't that require Fox to argue that they're in the space launch business to demonstrate the potential for confusion?

We have launched a native ad diagnostic that lets you see how a piece of content (typically paid) has performed.

What we do that is different in this is estimate the earned media impressions based on our own network wide dataset. It's a great way to compare the relative performance of a couple of pieces of content. Ideally yours versus a competitors :)

Whack in a few pieces of content to see how it performed - we have a couple of examples there.

Over time we'll roll out more data as we can.
“I am really excited about the possibility of data also, to improve health,” said Page. “Imagine you had the ability to search people's medical records in the US.” Since it should be a well know fact that in ad subsidized business model the user is the product, and the customer is the advertiser, who do you think would be the clients of peoples "health data" Insurance companies? Others? Do n't you think that Google actually becomes kind of creepy lately?
Thanks for the responses.

I think eventually moving to a limited company is the way to go, however I spoke to an accountant earlier and based on my estimated turnover of 3-4K from September to April, he recommended I start as a sole proprietor to keep costs down. I think keeping costs down is going to have to be a priority, since i'm building from nothing. I'm based in the UK, so one-member LLC's arn't an option - it's "sole trader" or "Limited Company" with nothing in-between.

In terms of liability, I may take out some insurance just to cover myself in case of lawsuits.

Interesting - when you have 20 people working for you, and you need someone to manage your clients and their projects and timelines, and also figure out what your your staff should be working on, and also balance staff requests for holiday leave and sick leave, what do you plan on calling that person?
Unfortunately, it doesn't even matter. If the reader detects that you have a chip card, you cannot use the magstripe even if your chip is faulty. The error you will get, after swiping the card, entering the amount and then pressing enter waiting for confirmation will be "PLEASE INSERT CARD". Quite vague but that's exactly what you get.
