Hey coffee, thank you very much for your insights! It's appreciated :)

I actually wound up converting 4% of the 2200 to one-time paid accounts, and am experiencing a lot higher use with the new version. 20% of visits result in 2 or more people collaborating on a file.

Sadly I'm struggling to get actual monthly/yearly subscriptions, however I think this is more of a CTA problem than a problem with the product. I really need to focus on getting the landing page better, and having a better CTA within the app.

Thanks again!
That's true, but you didn't mention that prior to distributing economic power equally, leftists must first centralize it. Further, as a means of administrating the continued equitable distribution of monies, political power is gathered in institutions.

That's not the only reason, though; many leftists do not actually believe in distributing political power at all. The position that the state has a complete monopoly on the use of force is an example of this.
Some say this is an "inevitable" result of pushing boundaries. No. This is the result of a poorly managed program.

Some of the boundaries that are being pushed are how much oversight, how meticulous, etc you have to be. In other words, how well you have to manage the program, how tight a ship you keep.

Keeping a tight ship raises costs, and isn't the big emphasis of all this privatized space travel on reducing costs?
> UUIDs are really unnecessarily long for no good reason.

Their purpose is to be universally unique, presumably indefinitely. The practical choice is to align on a power of 2.

When UUIDs were invented, they were based on a MAC address plus a timestamp. MAC addresses are 48 bits, leaving 16 bits. Of these, between 1 and 3 are used up giving the variant code and another four bits are used giving the version code.

If they'd used 64 bits, there'd be between 8 and 11 bits left for a unique timestamp. Which is OK, but not a very strong guarantee for a "unique" scheme.

As it happens the length has made it possible to create multiple versions of UUIDs that are generated in different ways. UUID has been successful at separating the concerns of the structure of the ID from how it is generated. Most alternative schemes are effectively implementation-defined.

>I think you'll find that it hard to argue that the efforts of exploration are linked to our industrial pillage of the planet.

It might be hard to argue that our industrial pillage of the planet is solely a result of exploration. Anything weaker than that and I think you have the tougher position.
This is a valid certificate issued by GlobalSign, parse it yourself (the link is in the post)

(well, now revoked, but still...)
While true, it is also not as direct of a threat. CO2 is affecting us now, whereas asteroids, etc., are (thankfully) only possibilities. Serious ones, to be certain, but not immediately threatening.

CO2 is a direct and immediate threat.
Thanks. I expected the downvotes. But it breaks my heart that we have such a beautiful planet and we treat it like a trash heap, all the while dreaming of Mars and whatnot. Let's put our own house in order before we go off travelling.

Look, it's good to know yourself. The probability of getting seriously messed by acid is extremely low, but the number one risk factor for a bad trip is being afraid of having a bad trip. Just don't worry about it and if someday you feel curious, just relax and do it. It sounds like you have a pretty good perspective.

Also, I will bet you that it wasn't (just) acid that fucked that girl up. Concerts are a great place to be exposed to all kinds of interesting substances.

I guarantee you that if there was sufficient profit motive, you'd see hundreds of companies being formed to go to space.

Right now the risk makes it too expensive, so the profit isn't there. Much of the work Virgin Galactic and the others are doing will lower the cost eventually. When it gets low enough, there will be people lining up around the block to become asteroid miners, etc.

Lack of willing people will never be a problem.
This is all true, and I'm not here to say the original implementers did anything wrong. As you say though, UUIDs are a general solution, which means they're not going to be optimal for every problem.
I love Lua just as much as everyone else but I don't understand the need for eLua.

Lua was already designed for embedded use.

After reading the overview of eLua, I don't understand what it brings that standard Lua doesn't already provide.

http://www.eluaproject.net/overview

Anyone care to elaborate.

Edit: OT. Does anyone know what Mike Pall is working on since it's not LuaJit these days? http://luajit.org/sponsors.html
Yea those sound like good results.

It would be interesting to see, over say 1,000 free trials, how many you could covert into monthly subscriptions and understand if the numbers I mention align or not.

Sounds like you may do much better. Would love to hear the results when/if you figure it out.
Pre September 11, in Australia (early 2000, IIRC) - you can get a passport in as little as three hours if you have confirmed reservations on a flight (and can show the flight was recently booked - i.e. you didn’t sit on your ass til the last second before dealing with passports).
You know how the rhythm to "We Will Rock You" by Queen goes

Stomp Stomp Clap, Stomp Stomp Clap

The "Claps" are on 2 and 4, the first stomps of the pairs are on 1 and 3. Now imagine some boob wearing his sunglasses like a hat and a popped collar starts clapping on 1 and 3:

Stomp Stomp Clap, Stomp Stomp Clap
Clap Clap

That'd be annoying. The looks on Harry Connick Jr.'s face before he fixes the clapping tell it all.
Sharyl Attkisson releases video of apparent computer hack
any vehicle that is dependent upon currently available propulsion systems is a waste of time.

So... what, we just halt development of all vehicles, globally, period? Bye-bye trains, planes, cars, bicycles, and buses?

You can't develop the future of transportation or the future of propulsion systems if you literally shut down global commerce.

Besides, an airplane (for example) is not wedded to the engine. Developments in prop planes carried over directly to jet planes, once the jet engine matured. Any future propulsion system that can replace jet engines will probably not be hard to work into many plane designs of the day.
UUIDs are optimal for every problem, in that they are unique and fairly fast to generate. There can be no better solution than that, except maybe to save a few bits. And we're only talking about 16 bytes here; not much to complain about. They're cheap at the price.
> There are many, many examples of folks rich off of equity.

This is true, but you need to look at who they actually are. The majority of folks who become fabulously wealthy off of equity (read: owning a piece of a business) are the folks who start those businesses and manage to hold on to most or all of the equity.

Most of these businesses are obviously not in tech, but if you want to filter out non-tech companies, the power law distribution of equity-derived wealth in Silicon Valley still doesn't favor employees, even those who join companies early on.
This makes me think of all those crazy warning labels that warn you not to do some incredibly stupid thing (ie "don't use the hair dryer while sleeping"). You know every dumb warning has some sort of story behind it. :)
Refreshing is exactly what we're going for!
Can you justify this? I don't understand why that should be. (I also suspect that sending one person to Mars for a day will cost an order of magnitude more than all the remote hardware we've sent so far, so the comparison is unfair.)
1) One of my high school buddies who went to the Courant institute for his math Ph.D. defended his thesis and then it turned out his proof was one that his own advisor had completed 10 years ago in a side note to a publication of a bigger result. They still gave him the Ph.D. (and I think the advisor was reprimanded); he wound up in finance.

2) Although I'm a biochemist, I did a math degree at the UofC - one memorable lecture was the analysis class lecture where we proved that pi was irrational (Professor Carlos Kenig). It started with the assertion, "assume pi is less than 6". Then he said, "actually it doesn't really matter what the number is it still works, I don't know how to count past 2, I'm sure 6 is big enough."
No, but I think most people overoptimise on the shiny stuff ("oooooh, I saved some bits!") over the important stuff (nasty surprises, several years from now).

There's no reason for everybody to stay home and do housekeeping, then there's a big beautiful universe out there. Dare to dream big!
The accidents this week seem to have no bearing on that.

It may or may not be true, but it's the same thing it was last week.
Well, sure. Just look at all the jobs that are still being done by humans. Even fairly simple and formulaic jobs like working in a fast food restaurant are still in the human domain (that may be starting to change, finally, but it hasn't happened yet).

For that matter, look at the problem of operating an autonomous vehicle right here on Earth. Everyone from DARPA to MIT to Carnegie-Mellon to Google has been working on that one for the last sixty years or so. It's now gotten to where it kinda works. Sorta. In some conditions.

Remote control doesn't work well when there's a large speed-of-light lag between the earthbound operator and the vehicle. Mars is 6 minutes away, round trip, minimum and that's about the best case. For the outer planets, forget it. The Jupiter system is at least an hour round-trip (not that we'd be landing people on Jupiter itself, but there's a lot of interesting stuff in the system).

Your vehicle is toast long before you figure out that there's a problem.
Certainly I agree that UUIDs aren't going to collide. But UUIDs were created to solve a problem most people don't have - how to ensure unique IDs when there is absolutely no communication between the parties generating the IDs. The article was suggesting one alternative to the UUID, and I suggested another.
And yet I know several personally. Wealthy off of equity from being early employees. Maybe half a dozen. That's enough to make a person believe.
"The URL is as much a part of the UX as anything else."

Given what we've seen from the browser vendors lately (hiding bits of the address bar, etc), I'd say there's a lot of momentum to disagree with that statement.
You're focusing on books at the moment? looks like a neat little platform. Kudos, going to pass this along to some animator friends
The switch happens around the 0:40 mark, for those who may have thought that they missed it (as I almost did)
Yeah, mixing engineering and call center employee numbers in the same graph does make me think. It mostly makes me think diversity numbers in jobs that make more than $10 or $12 an hour are shit.
Sure but why? We have UUID's and good generators. Run with it.

UUIDs solve a problem many, many people do have - identifying things over time and space - without having to even consider communication/coordination. That's a very powerful property.
Looks like some changes are afoot/happened at YC. They are very sophisticated and deliberate in their PR pushes, so looks like Trevor has been leading the charge since PG is clearly stepping back.
Are you suggesting we send several generations of robots to Mars first? That's a great idea and exactly what we have been doing for decades.
Worth noting from the course listing that this is an English/Creative Writing class, not a Computer Science class. So I imagine you would be writing papers about wasting time on the internet rather than actually doing so.
I am entertained by the relation between the last two quotes in the article.
I think you're kind of missing the point. The Alaska crab program doesn't come to a complete stop for a couple years while there's an investigation and an attempt to make it safer. It won't be on the cover of the NYT. You don't need to go to Congress and request an additional $1.7 billion for another ship.

We are moving into Space at a snail's pace because we keep insisting on spending lots of money to try and send humans there "safely", and that's not really working out so well for us.
That was my thinking and certainly would help to have someone negotiate and present you properly. I am not looking but if you ping me, we can be in touch. My background is rails/javascript, I am lead at parkwhiz at the moment.

I always felt that relationship between recruiters and us was not right, both sides are not motivated to build relationships. I did build some and got some really nice people to help me when I need it. But this is more exception then the rule.
And so we just tell everyone in the space agency "Sorry guys, but we can't do any more space stuff besides ground-based telescopes until we come up with a better propulsion system. So we'll keep about 100 of you on board to come up with that and the rest of you are fired."

Meanwhile, all of the derivative research (effects of zero gravity, life support systems, shielding, re-entry, etc) stagnates. And I guess we should dismantle our satellite systems as well, since they require rockets to achieve orbit.

Maybe we should ban all cars while we're at it, since they pollute our environment. We should shut down the evil factories, too, so no electric cars, either.

Yup, we can just sit in a circle, singing kumbayah while we wait for that miraculous perfect power source that someone else will develop for us. Then, and only THEN, can we continue with "progress".
... Also, there was Neil Armstrong's ejection from the Lunar Landing Research Vehicle in 1966:

http://en.wikipedia.org/wiki/Lunar_Landing_Research_Vehicle

(And I see another test pilot, Joe Algranti, also had a very close call flying a second-generation LLTV -- ejecting 0.6 seconds before it crashed!)

NASA came very close to losing more astronauts during mission prep for Apollo, in addition to the Apollo 1 crew. (Even if we leave aside the four astronauts killed in T-38 crashes in the 1960s.)
Thanks Supreme Leader (former) of USSR aka 'the evil empire.'
We are friends and the question:

How did the USSR develop H-bombs so fast?

1.)of course there were NO SPIES and or alleged 'collaborators inside
the USA system.'

2.)there's a long history of autoiobography memoirs of leaders of
alleged 'EVIL EMPIRE.' Yeltsin is mentioned by name in book by
DEFECTOR Albek, Biohazard - secret biowar weapons.

3.)Yeltsin calls it a 'research facility' and it is true that it was inside
a 'milk factory' - going by memory, so check the book.

4.)Did the USSR need computers like Intel chip with the
obvioius flaws of sinh, transcendental numbers buillt into the
instruction set architecture?

5.)Answer: everything fails in the USSR empire EXCEPT FOR
excellent education as leaders in math and physics and
moscow ballet who not works for Cirque du Soleil.

6.) The SECRET of GOOGLE TALENT? recruit from russia and
promise plenty of vodka drinks / free snacks.

7.)simply review Khrushchev's flattery speech against the background
of the Russian tank. The result of Russia vs. Finland was the
FINLAND inventors making MOLOTOV COCKTAILS.
These homemade grenades would set the engine air filter on fire
resulting in engine exposions.

Finland has NO grenades. Allegedly double crossed by Britain and
the allies. Tanks were pinned down by children pouring water to
make slick ice skating ponds for the USSR TANKS.

So, the Russian Tanks had advanced designs and deep thinking.
The manufacturing was horrible.

12.)Supreme leader former of USSR Khrushchev is sadly misinformed.
"comrade HN of the first order." Please do not laugh.

Much of the books on H bomb development show the
trial and error and strong need for basic physics, rather than the
IBM Microsoft Windows software game emulations, IMHO.

As the USSR defector who ran the bioweapons labs put it
the scientists and organizational structures were filled with
KGB agents.

The KGB agents were 'incompetent scientists' who seem to be
only interested in snooping, rather than doing real work.
The TOP KGB had 2 or 4 phones on their desks and often no
PC computer, as they had NO ENGINEERING BACKGROUND.

So, support of scientists and engineers BULIDING THE H BOMB
with ADVANCED IBM computers is unlikely in such a culture of
paranoia.

PS. many of the KGB... they are gone so insert other 3 letter acronym
is going back to typewriters and paper. It must be a capitalist
plot this Microsoft Windows aka 'Evil Empire.'

insert your favorite quote from Austin Powers movie here.
PPS. the story of BIOHAZARD by USSR defector is much more
interesting. no need for very complex nuclear codes and the
ADVANCED IBM computers.
Here's another great one: a certain well known mathematican, we'll call him Professor P.T. (these are not his initials...), upon his arrival at Harvard University, was scheduled to teach Math 1a (the first semester of freshman calculus.)

He asked his fellow faculty members what he was supposed to teach in this course, and they told him: limits, continuity, differentiability, and a little bit of indefinite integration.

The next day he came back and asked, "What am I supposed to cover in the second lecture?""

The funny thing about this is that we covered all of that in a total of 6 hours (2 hours per day) during my first year in CPGE.
In this context, they mean embedded devices (typically running machine code on non-x86 architecture CPUs: ARM, AVR, etc).

They are either providing means to compile Lua code to machine code (or an interpreter/VM running on controller and executing Lua code). Also, they have unified hardware abstraction layer for all the different architectures and controlls supported, so that operating peripherals feels the same on all platforms.
"x The Alaska crab program doesn't come to a complete stop for a couple years while there's an investigation"

Neither will Virgin Galactic.

"You don't need to go to Congress and request an additional $1.7 billion for another ship."

Neither does Richard Branson.
So if the x86-64 ABI is suboptimal for getting a stracktrace, can anyone name an architecture's ABI that is better, and in what way?
That's a really grate way to sell tickets: "We now know just how careless we can be to limit in flight explosions to just one per year!" You can't use the same attitude that's now common in software startups with space vehicles, or any vehicles for that matter. "Ship now and fix problems later" does not work with real world products, and to be honest, should be avoided in software as well.
Hi again bad_user,

Glad your collection of best practices got the attention and discussion they deserved today. I notice you posted them to HN 8 days ago and nothing. Unpredictable eh?

One more request, with your best practice "3.2. MUST NOT put things in Play's Global" - could you add an example of the correct way to "come up with your own freaking namespace"?

I assume putting authentication in there like SecureSocial does is ok?
I would definitely pay. It is quite uncomfortable to sell yourself.

Perhaps here is a great idea for a startup!
there's no need not in this day and age to have test pilots. If they use computers, they can debug the engine in flight conditions by running maybe ten times as many test flights.

Delays of months between flights are dangerous. Until you have a 1000-10,000 flights to build up operational data and envelope, this is a death trap causing unnecessary deaths.
I think armchair quarterbacking is reckless and inexcusable. These people has been working on airplanes and space crafts for some time now and I would trust their judgment. Especially given that they put their own lives on the line.
actually the notion that european music is "harmonically rich and rhythmically unsophisticated" is incorrect; it's relatively modern phenomenon that the rhythms in european music were simplified. Traditional eastern european rhythms are incredibly complex and western european liturgical and vernacular music tended to have complex ryhthms until around the 16-17th century.

IIRC this was basically an effect of the church decided to try to monopolize music in the service of liturgy and "dumb down" the music so that everyone could participate in hymnals, etc.

This could also partially be a result of music printing; it's harder to notate complex rhythms - if you've ever sung medieval music that's pushed into modern notation, sometimes wierd things happen, like time signatures that don't quite line up with the all of the music lines because polyphony is going on; invasions of 3/4 measures in an otherwise 2/4 song, etc.
Gordon Mah Ung's Farewell Maximum PC
I disagree. With 1.23 billion users[0], Facebook is easily one of the most visited websites on the planet. Also up there? Google.

Convenience is winning the war, and that's only increasing. All data points to even more invasiveness of products, and even more acceptance by people. The people you talk to simply don't outweigh the greater voice of the sum total of users of the Internet.

There is no revolution. Nothing is fermenting, and there is no momentum, except from the hacker elite (us), and that's not going to change, if stock prices and usage rates are any indication.

No lag in working with the document, potentially signifying real close proximity. If you want to buy the narrative, that is. Heck, I can RDP in to my pc with another pc/laptop on a directly wired network, and still have splurges of x,y mouse mapping madness, often requiring a do-over (even if its just a few pixel-wide adjustments), none of that is apparent here, which suggests shenanigans, or a patched, improved RDP. Release the source! ok, that was kinda dumb.
I'm surprised he can count to 2. In CS it's just 0, 1, infinity.

Depends on what you read into "clever", I'd say. The standard for novelty that the USPTO uses makes anything "obvious to a person having ordinary skill in the art to which the subject matter pertains" non-patentable.

Great, I'll try to remember this to use it.

Actually, it could happen with chemical rockets -- if we abandon the idea of sending canned monkeys beyond the atmosphere.

We can afford to send up a couple of hundred tons of prokaryotic spores every year until the cows come home, with solar sails to get their packages up above solar escape velocity. Over a few decades or centuries that's a lot of unicellular organisms to scatter on the direction of exoplanets; we can hope that in a few million years one or another strikes edible dirt and begins to reproduce.

This is, however, not as mythically resonant as "space: the final frontier" ...
It also shows that the crew capsule doesn't survive rapid dissassembly of the engine. Which is another thing to work on. Sad to see this so quickly on the heels of the Orbital failure.
