I'm not a troll, I'm just confused by all of these global warming claims.

All politics aside, I've reached the point where I'm not sure who to believe anymore. On one hand I see stories such as TFA describing compelling AGW evidence that seems convincing, but on the other hand I see anti-AGW information that seems even more convincing. Could some objective person please take a look here and tell me who is actually lying?

When I read stories about data manipulation I get concerned. There appears to be clear evidence that the surface temperature records have been undergoing continuous retroactive modification. I understand that there may be some scientific rationale for making such modifications, but I don't have enough details to form a rational judgement. Were the error bars in the original data wrong? If not, then why do the adjustments exceed them by more than a factor of three (in many cases)? Why doesn't anyone point out that the unmodified data shows a completely different trend? Is the satellite temperature data wrong? If so, why, and why does it agree so well with the unmodified surface record? Why is it that none of the existing climate models produce accurate predictions based on historical data? Why should we trust those models to predict future trends when they can't reconcile historical data?

I know I'll probably get flamed for posting this, but I've decided to not post it anonymously anyway. Please leave the personal attacks out of your responses.

Thank you.

(I Started this comment over an hour ago so I hope this is still relevant.)

I'm betting they rolled out this software update in an attempt to correct for the problems described elsewhere regarding heaters staying on too long causing overheated rooms (and increased risk of fires). Apparently some Nest engineer(s) thought it would be a good idea to harvest power from two-wire thermostat systems but did not account for the fact that by harvesting power, they might lower the impedance of the load sufficiently for the heater to turn on. This fix should reduce the (significant) risk of fires associated with using the Nest thermostats, but now users will need to deal with dead batteries because of the reduced power harvesting.

Although I'm not a fan of everything they do, I respect their political activism. I follow the "YourAnonNews" twitter feed and I find many stories of interest that do not show up in the mainstream media. Just as in the normal population, there are bad people among them. One thing's for sure though; no matter whose side you're on, it always makes for good entertainment.

Comment Minor correction (Score 2) 99

Good article. However, there is one minor error: "A replica of the great seal is on display at the NSA National Cryptologic Museum."

The replica is at the International Spy Museum in Washington D.C. and the original is at the NSA Cryptological Museum.

I have seen them both and the replica is a very poor copy of the original wood carving.

Comment Windows vs. Linux vs. Andriod vs. IOS (Score 1) 352

I use terminal emulators on most popular platforms (excluding MacOS) and I have not yet found a perfect one. Windows has lots of good choices such as Hercules, PuTTY, Procomm, TeraTerm, uCon. The one real advantage that some of these have over anything available for Linux is the ability to throttle data being transmitted (such as an X-modem upload of a flash memory image). Another important feature missing from many of the Linux offerings is the ability to display serial line data as hex-ascii in realtime. Many embedded systems lack deep FIFOs or even interrupts so they will drop characters if the rate is too high. I have not seen a viable terminal program for Linux that handles this well. Aside from the built-in "cu", Linux has some pretty good offerings with Minicom and Kermit. Android has a built-in terminal which does a pretty good job. ConnectBot and SSHDroid are my favorite client/server. Sometimes I use SwiFTP to fill in the gaps. (Of course the GUI offerings such as ES File Explorer are good too.) IOS has limited offerings, but with the lack of serial ports I mainly just need SSH/FTP. SSH-Terminal does a very good job and even supports (some of) the X11 protocols. (For GUI I like Files Connect.)

Comment Yes, but can you trust your compiler tool chain? (Score 1) 130

This only works if Debian can guarantee the integrity of the development tool chain. See this >30 year old talk/paper by Ken Thompson describing the problem. Once inserted, the malware is persistent and invisible. Re-compiling your compiler and applications from known-good versions doesn't help.

Comment Perspective (Score 4, Insightful) 134

When considering whether or not it should be okay for the US government to have backdoor access to any device, one should also consider whether other governments should also have that same access. The answer shouldn't depend upon which government you support.

One should also remember that government employees with privileged access are people, and people can misuse the access they have.

We should recognize that the Fourth Amendment of the US Constitution was created to prevent this exact scenario. Law abiding people encrypt sensitive information to protect it from misuse by criminals, but the information can be misused by ANYONE with access.

Dividing a backdoor key between multiple parties simply creates a requirement that all parties agree to access the information before it can be accessed. It doesn't guarantee that the access will be lawful.

Comment Re:Go Dell (Score 2) 385

I think you meant to say E6440 not E6400. The E6400 is an ancient Core2Duo machine and is sadly underpowered. I recently bought a E6440 and replaced the 500GB (hybrid) drive with a 1TB Samsung EVO Pro (850). I also bumped the RAM up to 16GB. It's a very snappy lightweight machine. If a real workhorse is needed, get an M4800. Those are great as long as you aren't carrying them around much. I've still got a E6400, but I rarely use it anymore. My E6440 is a great portable machine. I've traveled with my M4800, but it's a real boat anchor.

I have Ubuntu Linux on all of the above mentioned Dell laptops and the only issue I've encountered is lack of networking capability (both WiFi and Ethernet) while using 12.04 on the M4800. This can be fixed by loading a newer kernel (3.13 instead of 3.2). The newer kernel is directly available from the Ubuntu repo, but obviously you need a network to do that. A quick workaround to get the networking going is to use a USB-to-Ethernet adapter for access to the repo. There are no issues with 14.04. Dell is still shipping 12.04 (they haven't upgraded their standard image to 14.04 yet), but their version of 12.04 includes the Dell patches to make everything work.

Comment Already in use elsewhere (such as Gig Ethernet) (Score 4, Informative) 47

The (copper) Gigabit Ethernet PHY transmits and receives simultaneously on four wire pairs. It accomplishes this with a hybrid that subtracts the transmitted signal from the one being received. Last year some newer WiFi access points debuted that could do the same thing with RF. (Gigabit Ethernet is technically RF too because each of the four wire pairs operate at around 125MHz. WiFi access points operate in the 2.4GHz and 5.4GHz bands.)
