sudo -s launches a shell in non interactive mode (which goes through .bashrc or .zshenv and .zshrc depending on your shell) whereas sudo -i emulates a usrer login which puts the shell in interactive mode (.profile, .zshenv)

Also -i does more stuff to simulate a login like setting $HOME and cd'ing there.

Usually you might want to use sudo -i or 'su -' which both simulate a login. But sudo su - really isn't needed any more since -i has been added

It still looks like East Texas is favorable for plaintiffs, and it still retains the reputation as the most favorable.
That makes sense, since most startups are technology users, rather than technology seller. e.g. for a startup selling tools/middleware, technology market-share is customer market-share.

Thinking further, startups might be early-adopters of new technology, that will eventually become mainstream. But it doesn't seem to be a reliable predictor, since many (most) new technologies don't reach critical mass before being replaced by the next new thing. eg. ASN.1 binary serialization format. http://en.wikipedia.org/wiki/Abstract_Syntax_Notation_One

When used as advertised, SVG is slow. But there's a way to use it that's actually much faster than Canvas for some purposes: batch up everything you want to render into a single blob of SVG text and then splat it on to the screen in one go using innerHTML. This is faster than drawing the same thing with a series of Canvas API calls and far faster than making incremental modifications to the SVG DOM.

I don't know about your target device. Is this for a kiosk, a game, a projected screen shomewhere?

I suggest using SlimDX, it has done wonders for me and it is really fast: http://slimdx.org/

Depending on the capabilities of your target device, you may choose XNA, which comes with a nice batch of features which does not necessarily has to involve games (I'm doing 3d mapping software and the speed is great, while displaying many many features on-screen).

A more important question should be: what do you want to draw? 2d or 3d? What have you tried already?

To play devil's advocate here, an investor SHOULD (although apparently few do) want to know about the 'potential' of the company after 500K users have signed up.

For this 'potential', not even the 500K means much. So, to understand this potential, what's an investor to do? One approach is to wait a few years, but then it's too late to invest. So, how can an investor understand in time to write a check to the entrepreneur? If I were writing checks, then I'd want a clear presentation in, say, a 'business plan' of just why the potential after the 500K users was so good.

Next, if I were an investor, I'd want this understanding of the potential after the 500K user BEFORE I wrote the seed stage check and before the 500K users had signed up. That is, I'd want before any checks were written a solid case made, on paper, that this was a good business direction.

I'd want to take that paper with that solid case, after the meeting with the entrepreneur, and study the case, think about it, etc. before deciding to write a check.

Actually, it really is possible to give good descriptions of significant projects just on paper and to do quite well evaluating the projects, again, just on paper. And, the evaluations can be so good that the subsequent execution can be quite reliable, even for leading edge projects. Examples? Well, there is a funder and user of technology. They are by a very wide margin the most important funder and user of high technology in Silicon Valley, the US, the world, and all of history in this solar system. Thankfully for US national security, this user is, yes, the US DoD. Some of their history includes WWII projects in radar, sonar, the proximity fuse, and the atom bomb. Then they did little things like the hydrogen bomb, ICBMs, SLBMs, GPS, stealth, the SR-71, the F-22, ARPAnet, aka, the Internet, little things like that. The evaluations were nearly all just on paper, and for approved projects the execution was good with very high reliability.

Evaluating projects on paper instead of just with 500K users can be important. Maybe you met the only VC left in the US ready, willing, and able to evaluate projects just on paper.

At Microsoft, I watched (from afar) the incredibly painful multi-year process of making a complex language runtime intended for one environment (.NET for IIS) satisfy the requirements of a very different environment (SQL Server). When fundamental design assumptions like "memory allocation failures can kill the process" have to change, it's a big deal.

Seems like process isolation a la fastcgi is the practical way to go, unless the V8 team itself wants V8 to be embeddable in a "reliable" way (meaning, it recovers from its own errors without corrupting the process it's embedded in).

You're exactly describing duck typing. Resolving it at compile time in a static, "safe" way is a useful feature to be sure, but that doesn't mean it's not duck typing.

Replace "Go" with "Python" in your final paragraph and it's just as true.

Implement __setitem__(key, value) and you can use it in a dict-like way such that you can say "foo[bar] = baz" where foo is an object of your defined type. Define __iter__ on your type and you can now say "for x in foo: ..."

This month's killer startups
I don't think anyone could give you a firm yes/no on that.

What is your major? Have you done anything that sets you out from the crowd (ran a successful startup already, etc).

To be honest, the answer might be "stay in school and complete your studies". I myself don't have a degree but then I have a technical background.
You are forgetting Eagle Claw, and the fiasco at Desert One.

Look, neither of us can prove our claims, since we weren't there. But I have read several news reports along these lines, that Obama pushed for more redundancy.

One might ask: why didn't the SEALs think of it? The answer can be (and here again, this is pure speculation just like yours) that the SEALs wanted the smallest possible contingent, to avoid being detected (2 helis are less likely to be detected as 4) and risking the Pakistanis' ire. But at some level, diplomatic considerations creep in; and Obama could have said (or thought) "I'll take care of the fallout; but I want you guys to be double-extra safe".

While it is easy to dismiss this news report as you did, I don't think that is the case here.

For example: in the photograph released by the WH (where everyone is huddled, watching the monitor), Obama is in a corner, and the military guy is centre stage. Don't you think if Obama was so self-promoting as you claim he is, that he would have maneuvered into a better shot? Maybe placed himself front-and-center, to show he's "in command" ??

In comparison: do you remember how Bush flew a jet onto the carrier, "Mission Accomplished" ? That is self-promotion.

Thanks in advance for any recommendation and please, feel free to recommend apps of your own creation.

Yeah but then Google is a multi billion dollar company while Backtype is a startup with only 4 people. BT also does way more analysis than Google in terms of user engagement etc. Google doesn't really dive into the data and make useful analytics out of that.

It's not about how much data, it's about how you utilize the data to obtain meaningful results.

A lot of people already see traveling as a big hassle and they feel they have been nickel-and-dimed by the airlines (no more hot meals like back in the day), they are groped and blasted with X-rays by TSA as if they are some tiny terrorists. (This is regardless that there are 2 separate entities involved, people see it as just one traveling experience).

So most people will do this ticket hack even if it saves them just $5, or even just out of spite ("You made me jump through hoops? OK, now you sit and wait for me, haha!" kind of reaction). I am not justifying it or saying they are right, just illustrating the possible thought process.

Now from a market point of view, airlines are trying to solve this insanely complicated problem on how to maximize their profits from all these seats on their flights. It is almost like trying to do central planning on an economy of a small country -- this seat on this flight should cost X because we think demand for it is Y, unless demand changes and then we can increase the price, and then there are different legs, through different hubs, other partner airlines that try to do the same, it is just so complicated. So they end up creating these inefficiencies with inadvertent arbitrage possibilities. And people are taking advantage. Apparently they know about it and they are trying to put all kind of threatening legal mumbo-jumbo in their fine print. But they can't enforce it.

I think as more people start finding out and doing this they could: 1) ban customers in the future, 2) make them pay a fee next time they purchase, 3) lobby the govt. to declare this a grave security concern and make TSA chase these people down 4) try to adjust their pricing and fair structure to do away with this inefficiency.

True. Bonobos are more closely related to humans. There's some incredibly fascinating information about how humans are related to bonobos in sexual behavior (and overall communal behavior) in the book Sex at Dawn. Highly recommended.
The first half of the article, which makes the point that there are enough contradictions in law to allow for the deduction of any politically desirable conclusions, is quite compelling. I believe that most judges are rather moderate in this respect, and usually choose to interpret law in ways that are close to generally accepted social norms; but the observation that there is a very great deal of subjective discretion involved in this process, and that the social norms do change from century to century is very acute.

The second half is, by comparison, a let down. I happen to believe that the state needs to have a monopoly of force, in part because there are regions that have tried a free market in violence (such as contemporary Somalia and 4th century BC Ancient Greece) and it hasn't worked so well for them. And a monopoly of force necessarily implies a monopoly of legislative and judiciary functions to guide that force in a manner that is not too harmful to the rest of society. It's no wonder the author waffles when confronted with the question of what market-based law would look like - it's simply a concept that can't be defined too precisely without making it look completely unpractical to even the most unbiased reader.

Also, the application is extremely lightweight and doesn't get in the way of the video --- a simple, yet powerful experience.

The difference between the graphics card in the Xbox360, and these is that the 360's runs at (i believe) 600MHz.

There is much more to a GPU than simply clock speed. Since modern GPUs do everything with programmable shader units, the number of units acting in parallel makes a big difference, as well as the efficiency of the units (cycles per instruction). Many mobile GPUs' shader units can be counted on one hand[1], while a modern AMD or nVidia GPU has hundreds (though the different architectures make a direct comparison of numbers almost meaningless).

[1] I had a hard time finding exact specs last time I looked, but I seem to remember reading about one popular SoC whose GPU had in the neighborhood of 4 pixel shader units.
Exactly. Oh no! Somebody got a stern talking-to. I am sure they learned their lesson. This is akin to a cop that murders an innocent bystander and gets a 10 day suspension with pay as punishment instead of 25 years in jail.

Corporate News 4: Facebook, Google mull tie-up with Skype
I don't think you can use Apple to make this point. Apple do not have a company colour and they just have one very simple logo: an apple (not a weird union of A, P, L & E). Software gets logos usually in the form of an icon. Hardware has iconic photography. Icons and logos change with time. This is sophisticated adult branding.
Yes, just like that. Inertia, rent-seeking and reflexive thinking are probably bigger threats to freedom than any latent imperialist tendencies in DC.
You may try alternating between blitting a texture of a circle and clearing the screen, depending on a check whether the time elapsed is over 0.033 ms.

The time elapsed should be in a fixed timestep, which is tied to the vsync. 0.033ms should be around 30 frames per second.

The trick here is timing. By folding, do you mean screen tearing?
Do you need to render the circle for a duration of 0.033ms and then hide it for the same amount of time, and then start again?

If you are rendering with GDI, going to DirectX will definitely help you.

Hope it helps at anything. I'm a bit sleepy, please excuse me if I'm a bit off the rail from your intended meaning.

In my case, I need to refill my 15 gallon tank 3 times for the whole roundtrip. So, my best case is 45 gallons, which at $4/gal is $180. It's true I'm left with some gas at the end, so perhaps that skews the calculation. If I could refill it with just enough, I could shave some bucks. But I prefer not to return home on empty fumes.

Next time you do the trip - calculate the cost. You'll see it's closer to the best airfare you can get on that route than you might think.

If you prefer to fully-load the airport commute and wait time, then you can equalize the time cost. And then you'll be comparing the actual costs against the benefits. I've found that the driving cost even not factoring in time and food / other stuff, is remarkably close to the airfare.

And don't forget the tolls. That adds close to $40. Blame the NJ Turnpike for much of that.
Apple has significant motivation to ditch x86 now that Intel has an effective monopoly in high end x86 chips. Intel's fab process is 2+ years ahead of the fabs used AMD and ARM competitors though, so Apple switching architectures will only make sense in the long run.

ARM competes because of a more power efficient architecture; however, this difference is less of an issue if Intel's fab process can get farther ahead of the competition.

In short term(next 4 years) Intel's lead fab lead will likely continue to grow, because Intel switched to Tri-Gate(FinFET) at the 22nm node while TSMC and others will not adopt similar technologies until 16nm node(2014 or later).
Yes - and if you have lots of baggage too. Something to consider.

Traveling with a family on a fairly short / medium-haul trip (no overnight stay necessary) with lots of baggage? Driving will trump airfare costs for certain.
Yet again the word ethics comes up when consumers attempt to act in their own best interest in a given marketplace. Why should it be ethics when it's just economics? The airline isn't chastised for being unethical when they make decisions in their economic interest, why should the consumer be?

To me that is a prime example of a self perpetuating bureaucracy. It is like a self-aware organ of a larger organism that refuses to die and does all it can to fight back and stay alive.

* For those who are wondering this is the Tennessee Valley Authority. Which was created during the Great Depression to help electrify the South. The South has pretty much been electrified but TVA still keeps on chugging along 80 years later.

I'd say that is definitely true, especially in America and the like.

In the developing world though, I imagine there are some huge advantages to the power consumption of this. These may make it feasible to run a computer lab off of solar panels.
