Welcome to Shrink
What did you expect them to do? Go home and go to sleep and come back in the morning to check the logs? Come on. They'd hardly close their eyes for a second with all the excitement.

They're all there monitoring the various systems because they're all responsible for various components of an incredibly complex piece of equipment.

Assuming the landing goes well, they all still need to be there to continually monitor the operation of the systems they're responsible for and provide feedback if things don't like how they expected - it's not just about landing there.

This is normal even when releasing a tiny piece of software; it's hardly surprising NASA do the same for a multi-billion dollar project.
Genuine excitement.
That's really cool. Would love it if they had some video, or alternatively made a visualization of the entire landing sequence using received data. Like for instance a video of the telemetry you took screenshots of.
It's A Matter Of Trust - Part 1
They made it very clear in the press conferences earlier in the day that they have no more control during EDL than the viewer watching it at home.

I don't think the control room was "nothing but show." They certainly could have all gone home, but given the time and energy invested in this mission over the last decade, It was importent to monitor the event as it happened even if it cannot be controlled.
This could be related to the new iPad mini and modified new iPad launch alongside the iPhone. I suspect that Apple is expediting review of updated applications to take advantage of new unannounced features in the next iteration of the iDevices.
That was my thought as well as I was watching the coverage. Not surprising given there are a lot of old school engineers at NASA/JPL.

That is the first time I've seen a real-life useful computer display actually look like something they dream up in the movies.

(counterexamples welcome!)
Pretty sure the GUI toolkit is Motif, window borders do look like gnome though.
I believe they said 232 meters at one point, not sure if that was 100% confirmed though
For the landing process, they were watching it unfold automatically and irreversibly on the 14-minute relativistic delay, just like us.

But I don't think that means their assembly there was "just for show". That's the best place to see every detail of how well things matched plans: to see discrepancies, in context and with collaborating peers, as soon as possible.

And now that it's down, there could be info that requires adaptive action. Even though interpreting such new data, devising a plan, and sending instructions would take hours or days, it's still a "control" function, just a slow and deliberate one.
Maybe the legendary Xv they used on Sojourney?

> GoPro has done a very good job finding the niche they needed to appeal to

I think they've done better than that: instead of finding a niche, they've found dozens if not hundreds of them. Each individual "extreme" sport is a tiny niche unable to support much of a video company, but by stumbling on the idea of various quality mounts and a solid (in all sense of the term), high-quality camera, gopro covers pretty much all sports at once. And from there, it spreads to every situation where a camera is "out in the open" where it might get banged up or fall.

That's not really a niche anymore.
I think the single-bit limitation is a real step backward.
But then, to decrease error probability arbitrarily close to zero, you need arbitrarily many parity bits. That is undesirable.

Shannon showed you can decrease it arbitrarily close to zero using a finite number of parity bits. Surprised?

Not content with that, Shannon showed how to compute the ratio of overhead you needed. He also showed that, if you used slightly less overhead than his formula, no matter how clever your code was, your error probability would be rather large.

Then, the reader felt humble and rather amazed.

About fifty years later, people started to figure out how to make codes (in general situations) that got very close to the best-possible ratio Shannon found.
I think a lot of people are getting a little sick of Apple's arrogance.

It was acknowledged that they didn't have any direct control over the landing. However, there's lots of work to be done immediately after and most obviously, it's incredibly exciting to see the data as soon as it is available and to know that years and years of hard work executed successfully.

Additionally, watching a room full of engineers "do their thing" does a lot to get the average layman excited about the research and science and may get schoolkids excited about the possibilities of space travel, STEM, etc.

What I find wonderfully ironic is that the "positive thinking" that was supposed to protect them from the fire probably increased the harm. As your link points out, the sweat on the bottom of the feet protects the firewalker from the hot coals. But, where does that sweat come from? In large part, it comes from being nervous. The positive thinking that Mr. Robbins encouraged could very well have reduced that nervousness, eroding the protection that his students had on their feet.

1) Discounts do not apply to "features", like data and text, which for most are now 50% or more of the monthly fee.
2) Family plans are rarely cheaper, unless your family members do not use their phones.
3, 4, 5) Irrelevant for unlimited prepaid plans.

I'm not sure there is a "misconception" -- the majority of users consume less than 2GB of data a month, so prepaid is cheaper option and can offer the exact same coverage (Straight Talk AT&T SIM).
The article makes a good case for the answer to its headline being yes.

Betteridge's Law isn't an irrefutable proof that the answer to all yes/no headlines is "no", and merely invoking it without further explanation is lazy.
Frankly that is better than any alternative they are really in a position to provide. I am sure it was hard for them to resist talking over it reading a bunch of tweets.

This depends on both a large density of users and readily available merchandise (e.g. a warehouse). Of course, in my experience, the only reason people go to eBay is for things they can't get on Amazon - collectibles, used clothing, items not manufactured anymore. None of these combine well with warehouses due to their relatively unique nature.

For one, the robot gearing was designed with zero backlash (well +/- 0.000001") using a novel set of EDMachining techniques developed to achieve this accuracy virtually no part distortion - which was reported in literature and trade journals. Eventually, this could lead to super precision/efficient mechanical systems in scientific instruments, micro-robotics, etc.

Arstechnica really have varied quality on their articles, I just can't believe this crap.

TLDR: Microsoft bundles a keyboard, that means that windows 8 has inferior touch to the competition.

Never mind that microsoft actually tries to make a tablet that is usable and not just a toy/large phone.

For me personally I'm a bit excited of the x86 version of the tablet, that truly is the first tablet I'd even consider purchasing (probably won't though). But regardless of what you think of the Surface, this article is pure crap.

But if you want your tablet to be just a tablet and to never force you to opt for conventional input devices, the message from Surface is loud and clear: Windows 8 isn't the operating system for you.

Clearly arstechnica isn't for me.

Seven E-Mail Marketing Mistakes to Avoid

Really the only downside for average consumers is that the gopro doesn't give as spectacular images in low light - for obvious reasons at that price point, and i haven't seen any alternatives that do much better. this is also an aspect that is rapidly improving.. right now, i don't see any way to jump on this bandwagon. they do it too well.
Yes, we could tinker away with all the computers from the early 80s. We were lucky, this lower level of access was unavoidable.

But what about today? One never needs to type "load" and "run". Instead of discovery by the kid, a parent who thinks programming might be interesting for their kid is a prerequisite. And then they need to be able to do the research and install perhaps Python. And then what?

Playing around with Lua inside of Codea sent me right back to the immediate gratification of my Apple ][

In the end, does the platform matter? When I was a kid, I took apart the TV so I could see what was inside. Curious kids today will be similarly compelled to jailbreak their iPad.

I'd be curious to know how many programmers there are here who are programmers because of a push in the right direction by an adult, or simply because there were curious kids.

You Know What's Cooler Than A Billion Dollars? A Billion Users.
I think the Curiosity team would object to your answer. They've been working on the project for almost a decade, have spent thousands (millions?) of man-hours on it, and have written 500,000 lines of code to control it. The dollar amount that has gone into building it is greater than the value of many fortune 500 companies!

There are probably some awesome innovations that came out of such a large project, it's a great question to ask.
That's amazing, I can't wait to see that :)
I think the difference here is pretty clear: If you want the best instruments you should look around internationally. There is so much diversity there, so much specialities, that you will always be able to find some places in the world that are exceptionally good at building them besides just the US.

However, if you actually want to get those things to the surface of Mars and let them do meaningful work, the best option is the US. ESA didn’t even manage a (successful) landing yet, Russia is failing constantly.
Exactly something like that I am looking for, thanks

This is a great inspiring article. However, I take issue with this bit:

"I’m 18 years old. I started to really buckle down and learn programming 2 months ago. I feel I missed a huge opportunity because I didn’t start learning earlier in life. I was raised in a city that is far from all the start-up hype. None of my peers are even remotely interested in web-developing. And it’s not because I’ve been hanging with the wrong group either."

The presumption here is that the 12 year-olds who did learn web development were either new a startup hub city, or had friends who were also interested.

Speaking in my case, that wasn't true. I started learning an actual programming language at 13 with Visual Basic as a freshman in High School. In Connecticut. But before that it was HTML and CSS. The barrier for actually learning web development is incredibly low; just view:source.

My point is, there's nothing stopping any 12 year old from learning the languages of the web; not time, not location, not friends. Only interest.

NASA TV Capture of MSL Curiosity Rover Landing on Mars
I think you're better off just charging per project. People are more comfortable paying $10k for some specialized help, even if it only takes 10 hours, than they are paying $1000/hour for 10 hours of work.

Something like what Paul Rand did when designing the NeXT logo. He charged $100k flat to "solve the problem" of creating a logo.

Fixed fees only work well when the client has a discrete problem that needs addressing, but in my experience those are the best projects anyway. Imagine a team of people struggling with some hard problem for 6 months and then you (because you're a specialist) solve it in 10 hours. Those are the absolute most fun things to do. Hero Projects.

I'm still not sure how this is economically viable. At the IRS rate of $0.55/mile and the average messenger pay of $12/hour, about four or more deliveries per hour would be needed to break even just for the hour. Add traffic and downtime for when the messenger has no deliveries and it doesn't seem possible.

For comparison, in Chicago a company called Dining-in has similar constraints -- delivering within about an hour a custom order. They charge $6.99 -- excluding the tip.
Mars Rover Landing a Success — What Happens Now?
This tweet reminded me of what's next:

"RT @DanielBrian: I love that @MarCuriosity launched Nov '11 but @NewHorizons2015 launched '06 & won't arrive @Pluto til 2015! Space is huge!"

https://twitter.com/NewHorizons2015/status/23236225947574272...

New Horzons is the spacecraft currently on its way to Pluto--it's expected to be in range in about three years or so.
I love webhooks - they provide a neat portable layer between services and devices.

Currently I have Growl set up on my desktop computer and run a number of desktop programs that talk to it. I have Growl set up to ping Prowl (previously Notifo, RIP), which in turn does a push notification to my iPhone.

Things like getting an email directly to me, or having something fail my continuous integration build system, or even my son logging onto our home computer hit my iPhone, and it's so damn easy to put together.

I was frustrated with the limitations of IFTTT - I still rely on it for a few things, but just running a simple .net program on my desktop computer that is on all the time gets me 90% of the way there. (Most of my use-cases are "if x happens, I want to know about it", the esoteric [to me] scenarios like saving every gmail to my dropbox or something are not interesting to me).
For that rate I'd maybe hire Simon Peyton Jones, but $1000 for iOS "optimization advice"? The market must be in a really bad place.
