While I am certainly not a statistician, 25 subjects in each group sounds suspect. "Twice as likely" always makes me wonder what the absolute numbers are...
If 3 people messed up the plot order on paper and 6 people on the kindle, that gives a result "twice as likely", but does that really mean this test would repeat similarly with 10000 subjects.

TFA says:

  "The Kindle readers performed significantly worse on the plot reconstruction measure, ie, when they were asked to place 14 events in the correct order."

all of them? a few of them? what is "significantly"?

Comment: Impact on the Network? (Score 1) 281

No mention was made on the impact on the network of a new iPhone release. While many users upgrade from one phone to another on the iPhone release date, a huge number of new devices are also suddenly unleashed on the network on that date.

I am thinking that the network might simply throttle back all responses until the shiny new users quit playing with their new devices and go back to their normal day-to-day usage.

No way to tell if those searching for "iPhone slow" were new device users or old device users....

The problem isn't one guy showing up and doing something cool. The problem is next year 100 guys show up all with their drones all wanting to fly through the same fireworks display...cuz its cool.

Guaranteed, a couple of those 100 will have had a few too many brewskys....and that will lead to a new level of creativity/coolness. And that will lead to hospital visits.

What he says and what he can do are two different things. I don't doubt that they are trying to work out a scheme where the screen identifies itself accurately, but I think it is much easier (and not unreasonable) to charge for resolution.

You want to watch 720p on your 15ft screen, have at it...but we have this 4K version that you may be interested in for only a few pennies more!

The comments at the end of the CISCO article flush out the fact that they noticed a line of malicious javascript at the end of a large number of .js files but they have no idea how it got there.

In fact the list of JS files given include many that are not even running on Linux servers.

From TFA:

"With today's amount of detection data, just signaling an alarm isn't enough. The operator/analyst should be able to understand the risk as well as the recommendation of each incident, in order to be able to prioritize."

My experience is that companies skimp on the 7x24 NetworkOperationCenter personnel. Get cheap "eyes" on the logs and then hope that they are trained to recognize what is going on.....In most cases they just forward to someone else, and when you get the 15 false positive everybody relaxes and assumes the 16th is false as well...this is where the professionalism comes in.

Watching the video I am guessing one of the challenges is managing the center of gravity of the entire system. It looked like there was a spotter in the background making sure it didn't fall forward when the load was lifted.

The suit will need software similar to the Segway which keeps the center of gravity appropriately positioned. But Segway just needs to roll forward or backward a small amount to keep the center of gravity in balance...this suit will need to correct all of the joint positions in concert which seems to be a more daunting calculation.

The other challenge will be the power supply....

I have been in the telecom industry for for many years. The issue that most people don't understand is that the infrastructure is "shared" amongst all subscribers and somebody has to pay for it.

One of the common questions I always got from Telco operators is "how many subscribers can your mobile system handle"? My snide answer is "100 billion"....as long as nobody makes any calls. The question they should be asking is "how many simultaneous calls can your system handle?". Then the answer becomes 100,000 peak busy hour calls. The Telco customer should know what their *expected calls per hour per subscriber* are and then they can calculate the number subscribers they can handle.

The "expected calls per hour per subscriber" (or expected bandwidth per subscriber in this case) changes the calculation significantly. Netflix and other content providers have been a game changer in recent years because they have drastically changed that number. The ISPs know they can't provide every subscriber peak bandwidth at the same time. When subscribers used their "promised bandwidth" in 2 second bursts to quickly load a WWW page, the ISPs had no problem providing it. But now that subscribers are demanding their "promised bandwidth" in 2 hour "bursts", the playing field changes dramatically. ISPs, of course, can engineer for that load, but then "somebody" needs to pay for it. That "somebody" is either the subscriber in the form of higher ISP subscription rates, or the content providers in the form of "throttling fees" which they will undoubtedly pass on to their customers or advertisers.

Net neutrality simply shifts who is paying for the cost of all that equipment for our access. One way the end user will end up paying for it directly, and the other way the end user pays for it indirectly through higher content fees, or goods and services that are more expensive due to higher advertising fees. In the end we all have to pay for it.

I tend to fall on the side of Net Neutrality (and consequently would be willing to pay the ISP more for access), because otherwise the big players (Netflix, Google, etc.) will become more entrenched as they are able to pay the throttling fees while some upstart with a great service can't afford it.

I agree...the blogger has two data points, connects them and thinks its a "trend".

If you look at the traceroutes at the bottom of the blog, which he seems to believe make an argument for his point, the top two IP addresses are different between business and residence. The "residential" route could simply be overloaded due to everybody firing up netflix when they get home.

The OP has a genuine beef that he should get better bandwidth to Netflix, but he would have made a much better argument if he would have posted speed results to YouTube, dslreports, and other diverse sites not hosted on AWS....

Until then just two data points connected by a straight line...

I second exiftool. Lots of options to rename files. If you rename files based on createtime and perhaps other fields like resolution you will end up with unique filenames and then you can filter the duplicates

Here is a quick command which will rename every file in a directory according to createDate

  exiftool "-FileNameCreateDate" -d "%Y%m%d_%H%M%S.%%e" DIR

If the files were all captured with the same device it is probably super easy since the exif info will be consistent. If the files are from lots of different sources...good luck.

I am guessing that the motivation has more to do with a couple of profs complaining that their courses were not being taken, or their reputations were demeaned because the averages sucked.

Certainly anybody can do the averages, but the time to gather the data and complete the calculation for every one of the courses a student would be considering is probably not something the average student will do. But if it is simply a click away, then all students will do it, and some professors will suffer as the ratings make them look bad.

is what the compromised software really was. I am guessing that these "devices" all used the same opensource embedded WWW server that had a vulnerability.

Probably the biggest issue is that the fridge makers embed this stuff and don't bother to test it for vulnerabilities, assuming that someone else has already done the testing.

While I am a big fan of opensource, blindly using it in a commercial product will lead to all sorts of these types of incidents.

You are missing the point of the OP. While not elegantly worded, the original request is valid....

What are your secret CLI commands? These are the things that go INSIDE those bash scripts that make bash useful....Or maybe a bash construct that makes life super easy.

A new F18 HTPC install that I just did has 1897 different commands in /usr/bin, and an F20 upgrade that has been in service for a number of years now has over 3300 "commands" in /usr/bin....While I like to think myself a BASH power user, I am guessing that I actually know only about 10-20% of those commands. I know that many of those commands start GUIs and are probably not useful as CLI. But there may be a nugget of gold in the other 70% that I have missed after all these years.

My list is of useful commands:
- "Handbrake-CLI" for converting videos. It uses ffmpeg under the hood, but I don't need to remember all those parameters...I could just script ffmpeg, but Handbrake-CLI has already done that.
- "netcat" for just about anything over a network
- "flite" (festival) for voice synthesis (although I just discovered espeak)
- "sox" for converting audio files
- "asterisk" for making outgoing voice calls (not strictly CLI, but I can trigger a synthesized outgoing voice call with a bash script)

The one command I haven't found, that I want, is a speech to text command that will output on the stdout.
