[first post; hope it's not over the top or off topic]

A Lua testimonial: I've actively used Lua since version 5.1 (current version) was released (has it been 3 years now?). On Windows (only). After buying and poring over PiL, 2nd ed, my first trial was to replace an existing commercial scripting language in my text editor. That was completely successful, and got me up the learning curve.

Since then I've adopted it as my scripting language of choice at work, where it has almost totally replaced Perl (my previous choice).

* Yes, library support is limited, and lack of native regex support is on rare occasions a pain, but in my line of work these have not been significant handicaps.

* As mentioned by others, writing your own Lua functions in C is very approachable. SWIG? Who needs it? I used Perl heavily for years and after reading the docs was scared aware from writing C code to interface to Perl (or Python). Of course the counterargument is that with those P* languages, you don't _need_ to add much code that can only be written in C. Touche.

* If I had more time on my hands to hack, I could see making Lua the core technology for all sorts of low-level system- and embedded-app development [I was a "FORTH dreamer" for years, but Lua realizes a lot of the same dreams that FORTH offered but (for me at least) didn't deliver on].

* Since Lua is so tiny, it's easy to incorporate it, full-source-distro plus statically compiled EXE, into a project it's used in. I do just that, and among the benefits: NO installation needed (I hate installers, and while users expect installers for Windows apps, they don't miss having to run them to get my tools). Users pull down the Lua EXE (including a few custom/downloaded libraries statically linked in) along with the (non-Lua related) source code they're developing (Lua helps with all aspects of their build process) from SCM, and it's ready to run. If need be, it can be copied elsewhere and run. It just works. I can't imagine doing that with Perl/Python, which are also used by others at work, with the usual install/synchronization issues across dozens of hosts.

* I also appreciate that the language's designers have demonstrated a clear commitment to keeping the core language definition as simple as possible.

I'm not dissing the P* languages, one of which I loved for years, but it's nice to find a simple tool that isn't lacking in power. I'll keep using it until a better one comes alone!

Well then in this case you have a people problem, not a software problem.

Where I once worked, the -> operator was forbidden to appear in the C code we wrote. In place of w->x or f->title you had to write stuff like WIN(w,x) or FRM(f,title). WIN, FRM and the like were just C preprocessor macros. This was all to allow for some kind of weird future structure compatibility manageable by tricky macro redefinitions but I was never quite convinced.

That's asking a lot of people to review 3 paragraphs.
Months ago (or was it years), there was a similar article on here. You (or someone else from your startup) suggested the same thing. I signed up. Even though watching your video or reading your blog doesn't tell me what you do at all.

Now looking back, no mail in that time. No blog posts for a year. In other words: You don't call! You don't write!

Most universities make a large part of their money through research - the money will always be there so I don't see colleges ever going away.

What about the value of the diploma? Sure, I could code out of high school. But now employers can see my resume, my GPA, and my college achievements and get a fair idea about my abilities. Unless there is a great innovator that can provide a great testing/grading service for topics covered by traditional university classes today, there is no way that the university system will start faltering.
" You're already generating a gemspec for GitHub, why not using it for RubyForge?"

Because then I first have to ask Tom to create new project for me. :)

That's not a tremendous barrier, but with GitHub, whenever I get some code that looks like something I can spin off as a gem, it's almost frictionless to do it GitHub style.

That said, I have to give Joe a spin and see how it stacks up against Mr. Bones, which is what I've been using.
Careful.

What counts as a great innovation in alternate energy today requires at least being competitive with existing technology, which has almost one hundred years of development by tens of thousands of engineers at thousands of companies.

That also applies to coal vs charcoal.
as a foodie and a programmer my only suggestion is: we like pictures of food. if you can incorporate that cleanly in your site (fetch pics related to the question, display as nice thumbnails) then your site will look much more inviting.
Well, it's not what I recommend for major sites or businesses at all, but I can only tell you that this has worked fabulously on forums that get 1 million+ views a month and has been working for more than two years. I didn't expect it to be so effective, either.

As rantfoil said, if you're Yahoo or GMail or some other major site, they'll fix their bot right away. Yet if you're at all below their radar, this is the sort of easy trick that can buy you some time for spam control replanning. This works great for web software that is constantly attacked by generic script kiddie bots. It's a good bit easier than switching entirely to a different system for blogs, forums, wiki, or CMS when your captcha is broken.
Ah....clever. thx.
Except that if there are 4000 planes in the sky, that does make (assuming the planes are not overlapping, which seems largely safe) the probability 4000 times larger than for one plane.

As long as the planes don't overlap, the flight hours is the correct number to use, because more planes in the sky gives higher probability. It's not the number of meteors that matter, but the number of "potential meteor strikes".

Equivalently, you can say that the probability of a meteor hitting any one plane at a given time is the fractional area taken up by planes, which if there are 4000 planes in the air is 4000*5.82e-13. (Again assuming the planes don't overlap, which since 5.82e-13<<1 is a safe assumption.)
I guess it all depends:

seen them in tabular format ? you know they're great :
have you seen them abused ? you think you know :
have you thought about it ? you think you know :
get the gist from this ? good :
I can't help you ;
Just to play this game a little further, the probability is probably (!) smaller, because those meteors are not distributed uniformly across the Earth. Due to the direction of motion of the Earth through space and its sense of rotation, most meteors hit the area that is facing forward in space. That's the area on Earth where it's between midnight and noon, with the maximally forward one at 6am, ie sunrise.

Since I suspect, due to the way civilization works, there are more planes flying between noon and midnight than between midnight and noon, and the ones that are flying during that time are mostly intercontinental flights that go preferentially across the pole, there are probably less planes than average where those meteors hit.

But now I'm just speculating. ;-)
Was I the only person who was a little surprised that they didn't mention YSlow by name? That strikes me as somewhat rude, though I know Yahoo and Google aren't exactly best buddies.

Steve Jobs Said to be Returning to Work at End of June
I'm stuck with ClearCase at my current job.

Before making each change, my team's 'architect' (almost hard to say without laughing/crying) copies her entire checkout folder to a backup folder she has created... painstakingly numbering each backup by date and time. Her explanation: this way she'll be able to revert anything that goes wrong.

So yeah, not real sure why we bother with ClearCase when we have team members implementing ad hoc, informally-specified, bug-ridden, slow implementations of half of Git.

I'm not sure hackers do love cash more than a challenge.
Actually, I think this is a pretty realistic - and appealing - view of startups, but it's also very much a description of what the experience of a VERY small startup is.

I think it's important to note that there are different stages of a startup's lifecycle. It's been my experience that venture funded startups aren't nearly as risky as people make them out to be.

My guess is that the typical venture funded startup has a lifespan of at least 4 years. That's probably close to how long the typical college grad will want/should stay at their first job.

Bottom line: join a startup, don't start one.
We agree - everything copies everything. It's continual movement forward.
Danc's Miraculously Flexible Game Prototyping Tiles
The interviewers disbelief that food money is so important reminds me of my first experience with startups. When I was an undergrad I worked for a doomed startup, and I remember with all the various government and other sources of support out there, absolutely noone was willing to pay for rent or food. I mean the money had to specifically be for hardware or the like, but the biggest hurdle is the day to day money. Even living with your parents you need to buy some of your own food. It's not in the least bit trivial.
since the article seems to imply that chiropractic care is quackery, I have to ask: What do people have against chiropractors?

I don't know anyone who has much against chiropractors PERSONALLY, as persons making a living, but the practice of chiropractic makes factual claims about how many disease conditions can be treated by manipulation of the spine, and those claims are bogus. The state I live in treats chiropractors as one of several kinds of state-licensed healing practitioners, and I think the major health insurance networks here do "evidence-based" evaluation of treatments and reimburse for chiropractic treatment of back pain. But there would be no evidence-based reason to reimburse chiropractic treatment for high blood pressure or arthritis or many other things that a chiropractic training program (there is one in my state) might claim that chiropractic treatment can help. In some cases there are public agencies that pay for people's treatments, and it is important that the payers get right which treatments work for which conditions.

It's Cold Cash, Not Cold Feet, Motivating Runaway Brides in China
Beyond initial capital investment, regulation, and entrenched competitors, there is the "long tail" of production: namely, that most engineered products are built from parts sourced from many different vendors, sometimes thousands of miles apart.

Add in fluctuating energy prices (read: shipping costs), medical insurance premiums that rise year on year, and it's difficult to see what your costs will look like in five years.

In short, I agree: it looks expensive out there.
These tools (like YSlow) are oh so interesting when your clients install them in their browser and examine the site you built for them. Now, I'll get to hear complaints that we used too many inefficient CSS selectors (and that we're incompetent), ignoring the fact that a .0003 millisecond makes no difference to the client's website. It's not Google's fault, but I just had to sigh when I saw some of the rules (I'll expect a call by tomorrow haha). :-)

Someone made a relevant comment on the post about the need to further segment power users into early adopters and lead users. This resonates with my own experience.

With no disrespect intended, the early adopters in many markets are a little like heroin junkies willing to try anything new for 5 minutes. This may look great from a user registration perspective but, in general, these people have very little interest in buying into your long term vision.

Coming from a B2B background, I'm still working out the best way to engage at a deep level connections made through online marketing for hosted apps and getting that long term buy-in, if it's even possible. It's easier (for me anyway) to do this face-to-face because there is a more solid context for the relationship.
Thunderstorms can kill in a variety of ways -- the turbulence isn't your only problem, although I wouldn't bet that a storm as severe as this one (50kft tops) couldn't have done it.

The kind of bumps you get in something like that aren't what you think of as turbulence in a plane. Airlines have radar and always go around the big cells. This one would have been strong enough to fling people out of their seats and kill them from blunt force impact with the interior of the plane.

Second, in a thunderstorm, you have lots of rain, which if strong enough can interfere with the engines. There is also hail which can do significant damage to the skin of the plane and make it very difficult to handle. Third, there is lightning, and while airliners are supposed to be able to take a lighting strike, there are different types of lightning, and "positive lighting" has been known to poke holes in airplanes otherwise believed to be protected. Fourth, there can be lots and lots of ice. Airbus has already issued a letter warning of the danger of pitot icing as a result of this crash, and they know that at least one of the airspeed indicators wasn't working properly, probably because it was iced over.

Furthermore, with extreme turbulence, it can be difficult to even read the instruments. With lighting going off all around you, no visible horizon, and you being vibrated and thrown around in your seatbelts, it is very easy to become disoriented and lose control, possibly to the point of overstressing the airframe and ripping it apart.

A thunderstorm like this is about the most dangerous place for an airplane to be. I'm certain that one way or another, that is what did them in.

Fluffy and superficial.

That only goes so far. And if you have people sitting in their apartments, living off contributions and tips, isn't it going to be easy for the powers that be to pay off a large number of bloggers? Won't the situation be manipulated to recreate the one we have today -- journalism as just an aggregate of PR from various sources -- just delivered more efficiently at lower cost?

I could actually see it working in the other direction. Things like YSlow highlight good technique in a (seemingly) objective way.

As for your issue, I would hope that if a client is savvy enough to check with these tools, they could also understand when you tell them what is important and what is not.

H(m) -> SHA1(SHA1(m)) is not the same hash function as H(m) -> SHA1(m).
It is not luck. The probability of the article is almost correct, because the multiplication of the numbers is a first order approximation to the exact result.

Using Taylor series, if A<1

(1-A)^B = 1 – B A + B(B-1)/2 A^2 - B(B-1)(B-2)/6 A^3 + B(B-1)(B-2)/24 A^4 - ...

so

1-(1-A)^B ~= B A - B(B-1)/2 A^2 + ...

And if A is small enough (A<<1)

1-(1-A)^B ~= B A - B(B-1)/2 A^2

So, AB is a good approximation and if B is big (B>>1) the second order correction is

-B(B-1)/2 A^2 ~= -(AB)^2 /2

Then, with A=5.7e-13 and B=750e6*125=9.4E10, then

Exact: 1-(1-A)^B = 0.0520
Approximation: AB = 0.0534
Second Order: -(AB)^2 /2 = -0.0014

Power users are definitely useful, but I find that catering too much to the power users (who are more willing to try new things and have more specific feature requests) results in the end in a product that may be a little overwhelming to new users.

But yes, the power users are very important and must be nurtured to help generate more users. They are your most vocal fans, and word of mouth is priceless.
I've been using VitaList, and the best part is that they have an API (JSON or XML). I made a small app that fills in the one thing Vitalist doesn't have, auto scheduling. I know there's calendars, but I like for some things to just show up in my todo at certain times of a month, or once every few months, or every other week and putting 'Do Laundry' on every friday in my calendar is no good. Calendars don't auto roll tasks onward too, and I might not do my laundry on Friday, but by fridays its time to do that in the upcoming few days, so a rolling todo is better. VitaList is iPhone friendly as well, so I get my todo to go.

Once I thought they had lost my data. Turns out if you change your password and log back in with your old password, you get some weird old data from I don't know when -- this resulted in my recreating about 75% of VitaList on a Friday, and then realized I had not lost my data and stopped. I'm keeping that code around, just in case they start charging for the API or something... :).

edit: one more thing, i find the view by context feature really handy - my contexts are "home" "work" "errands" - and being able to quickly group by that (or by project) is nice.

"Distractions"?

Distractions from what?

You're idealizing life. There's no goal; we don't get points for making it to outer space or for reaching a singularity or for uncovering the secrets of the universe. You get a certain number of years to fill up with "distractions", and then you die.

You may not appreciate sports, but they bring joy to millions of people -- probably to many millions more than NASA does, and in a greater capacity. Denigrating that is extraordinarily narrow-minded.

He's posted an update of sorts:

I don't think he gets into the issue on content and that is important. What he says is relevant but another nagging issue is that there is no "diversity" at Universities anymore. Academia is an ideological monolith and the sign hanging from their ivory towers states very clearly that "conservatives need not apply".

It's true that other sources of knowledge are "cutting into the franchise" but the franchise itself has turned into something more like the Klu Klux Klan than Doctor Know.
I noticed that too a while back.

Ah, yes - I mis calculated p(strike of any meteor) by a factor of 3500 (the # of planes in the sky, according to the article). I think this should be applied to the probability, not the count of the occasions - but the numbers are small enough that it doesn't make much difference.

p(one or meteor strikes) = 1 - ( (1 - p(strike of any meteor))^ (total # meteors) )

(assuming statistical independence, etc).
p(strike of any meteor) = 5.82e-13 * 3500 = 2.04E-9
(total # meteors) = 3000 * 365 * 20 (for testing over 20 years)

p(one or meteor strikes) = 0.0436 = 4.36%
