I think it's hard. I think it's REALLY hard - but I'm more than happy to learn, I just don't know what to do. And that's after reading Tim Ferris, signing up to various blog sites and reading as much as possible.

There seams to be plenty of books on marketing theory out there; but very little in the way of practical, actionable advice.

python's not necessarily slow -- are your tests typically CPU bound or I/O bound? If the latter, I suspect the difference between Python and other languages will be insignificant.

More powerful ARM CPUs (ARM7 or better IIRC) can take advantage of pypy.

I suppose it isn't too surprising they don't have any clip longer than 10 seconds in that video.

Lets guess that it is going 1.5m/s (a bit more than 5km/hr or 3.3 mph which is a brisk walking speed). And lets assume the typical rider is 75kg (about 165 lbs). that takes about a kW to get up to speed but you only need it once you get to speed and it looks like it gets there quickly so over 3 seconds or so, figure a 3k watt-seconds. Then driving along you're probably at 1/4 (really efficient) to 1/2 (more typical) power covering rolling friction. (more if you are going up hill [sin(grade) * mass]) so in that size "plate" you can get maybe 10Wh of battery? That puts run times in the 60 - 70 seconds range. Followed by a 30 - 90 minute charge cycle (depending on how aggressive you can be)

I love the form factor and the concept, but we just don't have energy density in our batteries yet AFAICT.
I wonder what efforts were made to 'business-ise' and what the initial plans were. Was it reliance on serendipity for the good work to attract cash? It seems odd at first look, and forgive me if I'm way off base, to contribute to the commons for the greater good and then begrudge it's use.

Perhaps future growth vectors could include building a more robust community and actually setting out business plans around the product. This would begin to tackle two of the author's biggest gripes, support and revenue.

The nginx 'pro features' model springs to mind, or of course support contracts that could open doors.
I don't understand who this is for. To be able to remain balanced on a small patch of ground that can zip around in any direction under your feet with no handholds requires MORE balance than ordinary walking. That means that almost anyone who could safely use this would have to be healthy enough to walk normally. Walking is almost as fast, vastly more flexible, convenient, reliable, cheap....

Yes, it's more tiring, but someone who could safely use one of these could also safely cruise around on a scooter with larger wheels and a handle for much higher speed, much lower cost, more stability, no fear of running out of power, better handling over uneven surfaces, etc.

The people who need powered transportation on walkways tend to be those with limited personal mobility, and most of them would be at great risk balanced on one of these things. They need something stable to sit on, not something unstable to stand on.

The best market I can think of for these things is relatively young, healthy workers gliding around the smooth floor of a very large warehouse all day long carrying small objects. But that's not how they seem to be positioning this thing, and most of those jobs will be robotized, because the little warehouse scooter doesn't really need the person.
When a NIF causes a crash it does take down the whole VM. I think the way to isolate NIFs is have them on their own nodes.

You can, in fact, prove non-existence deductively through proof by contradiction.

Proofs can be valid even if their premises (assumptions) are not true. Mathematics does not rest on the truth of it's assumptions, but on the validity of it's proofs.

If you can create an interesting system of proofs off of an a different sent of premises, then that can also be very useful (see non-euclidean geometry). If you can't create an interesting system, then those premises have no value.

I also disagree that all our reasoning about the world is probabilistic. By saying that all reasoning is inductive, you make you earlier assertion that "I'd say that when it comes to existence, it is always inductive." empty because you are claiming that all reasoning is inductive.

"there is no integer that is not a factor of another integer"

I believe this is a tautology. It is true by the definition of integers (which you provide in the statement itself). It therefore doesn't make a statement about non-existence, but rather, the quality of integers.
yeah, of course: nobody cares.
The major 'culture shock' difference I've heard from Vancouverites that have gone to Seattle is that the dense, urban lifestyle of Vancouver isn't quite as easy to take advantage of in Seattle. In Vancouver it's pretty easy to live without a car and bike everywhere in protected bike lanes, but Seattle is much more spread out, is more car oriented, with has weaker transit and cycling infrastructure, and the hills can be a drag.

This has not been a deal breaker for anyone I know in Seattle but they've mentioned their disappointment, having gotten used to a certain lifestyle in Vancouver. Depending your interests Vancouver's easily car free lifestyle might not matter at all, or it might be worth the paycut.
I don't think this concept of "beta male" even exists in reality. Seems to be just a way for a certain group of men to excuse themselves from making active positive changes in their own lives.
I'm not who you are replying to, but I am a developer at Merge who is excited to try out your toolkits! I think there are a ton of opportunities for medical image analysis in the PACS world. I really hope that IBM will challenge us with the task of integrating Watson-technology into the PACS workflow. We've got some really smart employees here and I am hopeful this represents a huge opportunity for us.

(Secretly I can't help but think the smart business decision is to "black box" the image analysis as much as possible, but I can't help but being giddy about it even so!)
Thanks!

To make it short: I am currently building a strategy online game as a browser-game (only a current browser and JavaScript is needed). I think, that currently most online games lack strategic/tactical depth and rely on almost all the same mechanics (city-building and build up the biggest army), with only small differences (topic, graphics and some minor mechanics are different, the basics are mostly the same).

I hope, that I can convince enough grognards that online-gaming can have depth.

Thanks to you I've found this great article: https://en.wikipedia.org/wiki/List_of_commercial_failures_in...

Also thanks for your comment, that's the reply I was hoping for. I think a lot of the reasons why and how games fail (commercially) have changed with things like social media and increased usage of stock game engines. Unfortunately most of the post mortems of failed (indie) games I've read are of rather bad games. This is what I've meant when I said I've never heard of a great failed game. The most vocal group are people with a bad game who feel like they're entitled to earn millions (rethoric hyperbole intended).
The Ellsberg Paradox
Do you have an example of one such characteristic that has been disproved?

I would posit the opposite: As the capability of our language to describe characteristics of god expands, it becomes harder to disprove god because the number of possible descriptions increases.

This really doesn't matter, the FBI nor anyone else will be dealing with decryption by building probabilistic modules on RNG generation using various given states and the average use of some one's mouse.

TrueCrypt like many other FDE's has 2 keys, your Data Encryption Key which is generated by the software using random values, and your Key Encryption Key which is generated from a pass phrase and no random data since it has to be generated every time.

The KEK is generated using a key derivation function most commonly PBKDF2, this is by far the easiest vector to attack because this vector is vulnerable to 2 fairly easy attacks.

Brute force against the KDF which generated the KEK and brute force against the user which generated the pass phrase.

Bad entropy or not the FBI will not be breaking AES anytime soon heck if AES can be broken atm with entropy as bad as some rolling a D20 the US government won't use it because you can be sure that some implementations of it in use by the USG have probably even shittier pseudo random number generators than that...
> You can assign multiple IAM roles to an instance profile, which is what is associated with an instance.

Perhaps there is some contradiction in the IAM docs, but I couldn't find that reference. This seems to indicate that only one role can be assigned to an instance profile:

"Note that only one role can be assigned to an Amazon EC2 at a time, and all applications on the instance share the same role and permissions." (first paragraph, last sentence)

Is it tough? There are only seven fundamental units. https://en.wikipedia.org/wiki/SI_base_unit

Just represent every unit in terms of them then it's good.

One problem with the array you came up is that the units are not orthogonal, since Joules = Newtons * Meters.
I don't understand the question. Your link has examples of closures right in it, so naturally if you're doing anything like that, you'll want them.
Cool how a small, very soft launch spiralled into a huge virtual launch party. The product caught people's imagination and interest, you'd have to conclude.
First off, it depends on the assumption that infinity exists.

Secondly, just because something is a tautology, does not mean it is not a statement about non-existence.
In addition to Web App Hacker's Handbook, I would like to recommend "Gray Hat Hacking The Ethical Handbook" (3rd or 4th Ed.) Focuses on the attack and defense in equal light.
That seems pretty unfeasible for a startup unless it already has significant traction. So it seems like bank startups are out of the question.

> But the worry is that in 2015, no matter how good your game is, the audience has way way way way too many amazing games to choose between.

And it has also become way too easy to acquire games. Back in the 1980/90's, unless I wanted a specific game, I could easily spend an hour in a store trying to decide which one game I could afford to buy.

Meanwhile, it took less than a minute to purchase Spider: Rite of the Shrouded Moon on Steam, looks like fun, cheers.
It sounds like you have more fundamental architecture issues. Language is mostly orthogonal to this and switching languages won't necessarily make anything better, though I personally find bash to be clumsy for writing anything large and kind of slow too.

So first, don't dismiss C. C still dominates in embedded environments for good reasons. Every processor has a C compiler, C is fast, C gives you a degree of compiler checking, C is small, and writing re-usable libraries in C is a well-understood thing (this is the basis of every Linux/Unix distro). And yes, you can write tests for C. Look at CTest for one.

If you really want a scripting language, then Lua is generally the top choice for embedded. Lua is tiny, fast, 100% ANSI C (which means you can port it anywhere because as mentioned, everybody has a C compiler), and Lua is extremely extensible for custom needs. Lua is also designed to interoperate with C so if you are really concerned with performance, you can pretty easily split up the performance sensitive stuff into C and write the rest in Lua.

A friend of mine who used to work at McDonalds, told that "custom" burgers are always made to order, so he advised that if you want a fresh hamburger, order a cheeseburger with no cheese - you'll get a fresh made to order hamburger and cheese on the side.
Compensation in the games industry varies wildly. In my opinion, this is because there are many people who have <5 years experience and few people who have 10+ years. The veterans have high salaries and other forms of compensation (profit sharing, bonuses) while newbies are given less than in an average consulting/web shop.
I'm using "nonlinear" in a very different sense, but thanks for the answer.
From the article:

Even though it looks tiny and so lightweight (it’s made of aluminum), it can easily carry 120kg and you can travel at max speed of 10 kmph for at least 12 km. After that you’ll probably need a re-charge, and apparently it’ll take 3 hours for that.

Essentially, you're saying they are flat-out lying.

Could be, of course. But that's quite a claim.
> Even in mathematics, if one doubts basic entities as numbers and their properties, the whole establishment of mathematics starts to crack, at least for that particualr one human being.

That's not how it works. Numbers are their properties. You are free to use any properties you want when you commit mathematics, and you will get different sorts of behavior from your numbers depending on your choices. There is nothing to doubt about a set of properties being itself. No 'establishment' tells you how numbers work. Use whatever you like.

I can see why. This argument goes beyond simply just landlords and rent into a critique about the dark sides of capitalism itself.

In capitalism you can not only own land as an landlord but you can also own labor. Someone who owns the corporation, can sit on the profits, dividends, and growth without producing actual GDP himself. It's very similar to the landlord situation. The owner of the corporation essentially sucks the lifeblood of the work output generated by employees while doing no work himself. Y-Combinator at its very core is a product of this system, hence the possible downvotes.

Capitalism is great, but landlords and freeloaders who get richer and richer without producing any GDP themselves is a huge negative attribute that is intrinsic to capitalism. Ironically, it is the hopeful opportunity of becoming a freeloader that drives the risk-taking entrepreneurial qualities which in turn make capitalism so effective.

It's worth noting that while Vancouver has absurdly expensive detached housing (East Van: $1.2 million[1], west side more) the rental prices in Vancouver (~$1200-1400 for single bedroom in new building) do not reach the absurd prices seen in SF.

Unlike SF, Vancouver builds plenty of condo apartment buildings, so if you wanted to buy a single bedroom apartment you could do so for $300k-400k. I'm not saying that's not expensive considering the average income in Vancouver, the real estate market is definitely in a bubble, but it's at least within reach, whereas detached housing prices exist in their own bizarre reality.

Andrew Zirm: An Astrophysicist with a Down-To-Earth Calling
First thoughts are offshore microstates, unregulated virtual currency banks, or be extremely well connected to financial and political figures. I'd be drawn towards an autonomous, low cost, high volume virtual operation. A traditional brick and mortar bank would seem an odd thing to start at this point in time, unless your operation could be mostly automated in some way.

What are you thinking?
Even if the oil and gas boom continues, it won't involve many people. Oil and gas wells, once producing, are unattended.
Also, this article says about Obama's father "His late father, Barack Obama, was a finance minister in Kenya" which differs from what the wikipedia page says about his father "senior economic analyst in the Ministry of Finance".
More complete quote from the article:

in late 1984 and early 1985, he was betrayed to the KGB. (CIA officials believe the informant was Edward Lee Howard, a one-time CIA trainee who had been fired after failing a series of polygraph tests. Howard, who defected to the Soviet Union after Tolkachev’s arrest, denied betraying the Soviet spy. Howard died in Moscow in 2002.)

The Official Story per Wikipedia and consistant with the implication he was just a trainee (https://en.wikipedia.org/wiki/Edward_Lee_Howard):

Howard was hired by the CIA in 1980 and was later joined by his wife, Mary, where they were both trained in intelligence and counter-intelligence methods. Shortly after the end of their training and before going on their first assignment, a routine polygraph test indicated that he had lied about past drug use, and he was fired by the CIA in 1983 shortly before he was to report to the CIA’s station at the American embassy in Moscow.

It's hard to imagine how he'd get the right sort of info on such a critical spy.
Pretty much zero, would guess it's probably even harder than just purely guessing the key at this point ;)

True Crypt also implements xor-encrypt-xor which means you don't only need to know where the data is but also to which blocks it was written to and what as int the adjacent blocks. Later versions of TrueCrypt implemented XTS which even made this more "complicated" to guess, especially when you tried intentionally to attack the block cipher by flooding it with data that you expect to be padded in a predictable manner.

I'm sorry but i for once would be really surprised if the US government or any other entity has actual cryptographic attacks against modern encryption standards that do not involve engineered back doors (And things like the ECC fiasco doesn't count since it's pretty unlikely that even with knowing the seed values the NSA could actually decrypt anything) into the cryptography software or the system in general.

They can and do of course attack the weak links and go after the users and their keys and password when they are vulnerable to be stolen.
One more thing. Be careful of "object oriented" design if you are thinking about shared libraries and re-usability. Depending on your definition of "object oriented" and the language you pick, it actually causes tighter coupling between components because the type system often encourages everything to be related.

Since you mentioned Go, Go's approach to object-oriented tends to use interfaces which tends to avoid this problem. But your milage will vary depending on the popular semantics of whatever language you choose and also the conventions library writers use if you choose to use pre-existing libraries.
Die, bitch.
So if I were to state "you have no understanding of logic" that would be meaningless?

I would argue that the statement does indeed have meaning, because you have some understanding of logic. If the statement had no meaning it would be impossible to disprove.

It is quite possible to create a meaningful definition that has no referent: "My first born child" is a statement that can have at most 1 referent but can also have 0 referents.

Just the fact that it is possible that a definition has 0 referents does not make that definition "a contradiction" or "meaningless".
Or it can be more likely a plea that he decrypts the drive on the condition it will not be used to press new charges against him?
What I wrote was a bit dense and extracting what I was try to say was not easy (this is bad writing on my part). What I was trying to say is the average intelligence of the children is the same as the average intelligence, but the actual values of the children will be scattered and this scattering will show a normal (bell curve) distribution. Putting this into numbers if the father has an IQ (g these days) of 110 and the mother an IQ of 150 then their children will be expected to have an average IQ of 130, but their actual IQs might be 115, 140, 160, and 100.
I've used them to build a serialization/deserialization library for a proprietary protocol. To cut down on needless boilerplate I had the metaclass build setter/getter/en- and decoders from a static member variable. Inspired also by how Django describes its data model.
I am staggered by how well this article describes the way I think, what i do and the impact of my work on my life.
If, I'm reading you right, I think you are saying there is a distinction between:

a) The thing itself
b) A name for the thing itself

The question is then, can there be a real b) if there is no corresponding "a)", the thing that is being named.

It would seem the obvious answer is, no. However, I'm sure you could try to construct some twisted logic in an attempt to allow it. Such a logic would probably have flaws (incompleteness theorems likely have something to do with it) and are likely near useless.

I would agree that there are multiple definitions of existence that can be considered fruitfully. However, as a matter of formal logic, attempting to disprove/prove the non-existence of a 'thing' [0] is a trap.

[0] I use quotes here, because I'm not sure anyone here has yet defined what exactly a 'thing' is. :)
I'm sorry but I can't belive anyone can take this site for a serious source.
