More importantly: why aren't TVs doing it? TVs should be turned off completely when you press the button, to save power. After that almost all smart TV boot up quite slowly. Which is sad :(
My GF's Samsung smart tv has to update at least once per week when you power it on. There're regular warnings for service unavailability. It spends time logging on each time you start it. Sometimes it won't even turn on when you press the button. It's a completely awful machine. I'd honestly rather have a CRT.
Can you not turn off the smart functionality and updates to use it as a monitor/traditional TV?

Pretty sure even most people with CS degrees could not configure Linux. It's pretty specialized knowledge as far as I can tell.
>Pretty sure even most people with CS degrees could not configure Linux. It certainly does not take a degree of any kind to "configure Linux". Not even if you're below average IQ.
Has nothing to do with intelligence.
This is just a different knowledge domain, and there is shockingly little overlap with a traditional CS education.

#94Our team was working on a vehicle telmatics platform ( connected cars ). We had a requirement in which the remote engine start time should be within 15 seconds from the time the customer clicked the start button on his phone. For this the QNX running in the vehicle had a fastboot mode , which came up within that timeframe , brought up the interfaces & established network connection to our server and started the car. Once the car is started , the system will go down and come back up in normal boot.
Now I know !

Roughly speaking it levels the playing field. With Open Source smart people and companies that attract smart people get an edge.
Good point! But the hazard is that the we risk getting FOSS software that is unnecessarily complex to configure because of this.
Configuration can be a pain. Sane defaults help and smart UIs help not to mention good documentation.
I've been playing with some software over the last week that has wiki for documentation and an active user forum with people willing to help. But it's completely disordered and incredibly hard to discover. Half the battle with usability is making it easy to use and understand.

#96An OS is recomputing the same functions over and over again when booting, so why not cache all of this, and make it instant?
The biggest problem with caching things during the boot process is that turning our devices off and on again will not magically solve our problems any more.
That's why there's always a seperate reboot option which tells the fairy to do her job.

I once had a brief conversation (via Reddit) with a guy using JACK for a commercial (embedded Linux) networked audio system. I wasn't aware of the exact specifics but I understand it was Sonos-style, embedded boards inside speakers. He wasn't particularly interested in talking about the work his team had done :P I think that proves your point.
This is a quite paradoxal phenomen that happens to some open source projects. The code is open and free, but some of the experts hold their knowledge very close to their chest. It's totally understandable since they of course need to make a living somehow, but it kind of defeats some of the benefits with open source.
I don't think it's such that the person in question doesn't want to share the knowledge, it's that imparting the knowledge is time consuming and draining.

#981 seconds seems a rather arbitrary measure. In HCI 100ms seems to be the value that's generally taken under which an action seems to be happening instantaneously [1] It's quite sad to see how we hardly use the computing power offered by our modern computers to actually speed up common tasks, but instead bloat it up with all kinds of stuff. [1] http://cogsci.stackexchange.com/questions/1664/what-is-the-t...
Even that may be debunked it seems it's now down to 13ms and that number is only due to testing equipment limitations of 13ms. According to "Mary Potter, an MIT professor of brain and cognitive sciences and senior author of the study".

To expand on this, its the difference between knowing a field of knowledge, lets take cooking, and how to use a tool, lets say a knife. While you can learn a lot about how to use a knife by going to culinary school much of the knife and the process surrounding what makes a good knife, good and bad knife, bad is very specific knowledge. The analogy kinda falls apart because you need to touch on the topics and metallurgy and industrial process but hopefully that paints a reasonable pictures. Linux is a tool, a very complicated tool with specific features. CS/SE/IS education is a very general set of skill which should apply across not just Linux but most/all of computing.

And QNX before that. But, that's a well-engineered, UNIX-like microkernel rather than Linux. Oh well...
QNX was open source for a while, what is surprising is that there doesnt appear to be an easily searcable version of the code available on google.
That was a bait and switch by management that I could tell. They got a bunch of contributions from the community then pulled it. Or just felt that it wasn't worthwhile after little contributions. I can't be sure.
Nonetheless, underlying technology is solid with that showing in Blackberry Playbook.
