Comment: MOOCs are more than classes (Score 1) 182

by davec (#47900777) Attached to: The MOOC Revolution That Wasn't

I've signed up for lots of MOOCs just to check out what is being covered, or what has changed since I took a class in college. I've also finished a couple of MOOCS that I thought were useful. I've also registered for MOOCs just so I can download the course materials to go over someday when I have spare time. I wouldn't count the times I didn't participate and finish the course as failures, I was just using the class in a different way.

And are we talking about a full BBQ, or just a singe? I'm not too concerned that 28,000 birds a year get a suntan!

I suspect that if fully cooked meals are dropping out of the sky at an alarming rate, there would be an issue with coyotes and other scavengers hanging out at the Sizzler. Maybe the the solution is to just add some ADA parking and a Coke Freestyle machine.

ok, so 28,000 per year, lets break that down.

with about 8 hours per day of operational time, it's 10 each hour. That's the high number. 1 every 2 minutes is 30 an hour, so you've already exaggerated 3x the exaggeration in the post.

80 birds a day? who is cleaning up the bodies? show me 1 picture of 80 dead birds at one of these facilities.

~3 birds each day seems like a lot of KFC for a power plant....

anyway, seems like the environmental impact is quite less than mining of coal etc etc, and more easily chirps, clicks, etc to scare the birds away? Or maybe a little metal eagle or hawk statue on the roof..

absolutely agreed. Though I don't have direct evidence to support this statement, I would guess that a neuron fires at a similar enough speed as a transistor. Consciousness is a very complex computation from billions of neurons *written in assembly* essentially. If/when we make an AI, it's likely to be compiled code running on a chip with less transistors than we have neurons, 100 Billion neurons vs 1.4Billion transistors in an i7 for instance.

That said, this is assuming that we limit consciousness to what humans perceive, the computer may have a somewhat different version of it. I suspect that we will try to build a human type consciousness into the machine though.

This is really the point. The $40K+ prosthetic is simply over engineered. It's a poor argument saying that we should support engineers, their families, their companies, etc so that they can charge a disabled person $40K when we could have a single developer make a much simpler product that can be produced at a local 3D fab shop or in the garage of an enterprising neighbor.

Clearly this is an early version, though fully functional. Improving aesthetics can certainly be an optional component. Today, a black or clear acrylic prosthetic would be of very little concern to many people and I only see that as becoming more of a non-issue.

The other interesting part of this is that someone in need of such a device could invest in the tech to customize and produce a device specific to their needs. maybe they have a palm, or less to work with. Customizing the device to suit them at their own pace with rapid prototyping changes their disability. The thriving makers movement can facilitate the sharing of schematics so you might find a near-ready model that you can alter to fit. maybe even spawn a boutique prosthetic shop in your town.

really, there are 3 options
1) a second array
2) tape (biggest are 5TB right now...)
3) online

1* RAID6 (or raid5+hot spare) would be 7x 4TB drives and could be built for about $1200 using a cheap workstation and external drives w/ freenas
2* tapes would be expensive and cumbersome IMHO. Also expensive!
3* I say this is an option but it's not realistic. if you have a typical 4Mbps upload from Cox/Charter/etc then the initial seed would something like 2 year!

Don't be a jerk! This is an absurd request. You get to record but your 'clients' cannot? I'm guessing the owners don't actually want to be in business. Even a no-camera policy is completely ridiculous for a fore-hire limo service.

This is where I'd like too see the defacto monopoly of cable companies broken by making them common carriers. Basically, do what the gov' did to telecos creating the iLEC and cLEC system. This way other carriers can buy fiber and get on the wire.

for many cities, the cable lines are actually owned by the municipality and managed by the cable company, so this would be a somewhat simple transition. DOCSIS already has the ability to allow this explicitly in the standard.

I'm using btsync as well. I have about 20 sites with various synced folders. I have two primary nodes at my office and at my home that have all folders synced, they are essentially where I create all folders. People each get their own folders (actually zfs volumes). I run ubuntu w/ zfs and dedup the storage pool.

When I create a small NAS, I use a refurb computer with ubuntu, zfs even for a single disk (for compression, dedup, snapshots), and samba to share the files at the site.

I use apache w/ webdav and a link for the .zfs/snaphosts directory to a history directory and to once daily snapshots. Can access the files through webdav AND access historical copies..
