Yeah, the numbering confused me as well when I first started looking at it, but it does make sense after a bit. You have the model class: i3, i5, and i7 and then you have the model numbers.

The marketting class tells you at a glance (for a given generation) how the CPUs compare: a 2nd gen i7 has more features and generally faster than a 2nd gen i5, etc... Then the model number shows the relative performance/feature within a given generation: 2500 has fewer features or performance than a 2700, etc...

What may not be apparent at first blush is that it is the model number that encodes the generation bit, not the model class. Tthey've gone through 4 generations of Core i7/i5/i3 and the marketting classes haven't changed. The model numbers have changed, though:

Core i7 965 (Nehalem)
Core i7 2700K (Sandy Bridge)
Core i7 3770K (Ivy Bridge)
Core i7 4770K (Haswell)

As you can see, the first digit encodes the generation of chip, with only the original Core i7 generation being the outlier. You can't usually compare across generations, since there are too many variables, though you can crudely estimate that a Zxxx model will be better than a Yxxx model.

The big pain is knowing what features a given chip has and for that you need http://ark.intel.com/

Do you have a 2012 model Nexus 7? That is what I have an never got an OTA push of Lollipop so I updated manually using the factory image. I'm wishing I hadn't. The tablet was slow enough with KitKat, but now it's essentially unusable. I don't know if it's the bad flash or what.

I don't know if others are getting the OTA for their Nexus 7 (2012), but it wouldn't surprise me if Google decided not to push it with all the problems many people are having with the update.

I remember watching one of those daytime court shows. The plaintif had asked his friend (the defendant) to drive his car and he got pulled over for going through a red light or somesuch. The plaintiff was telling the judge: "Everyone knows that green means go, yellow means slow down, and red means stop." The judge just looks at him and says: "Wrong. Green means it's legal to enter the intersection, red means it's illegal to enter the intersection (except when making a right hand turn where allowed), and yellow means that the light is about to change to red."

I think that was the most satisfied I've ever been watching a daytime court show.

1) You can still use rsyslog (or syslog-ng or ...) with journald if you want and I believe all the major distros still do: http://blog.gerhards.net/2013/...

You never want to turn off the engine while driving, since you lose power steering, power breaks, and other power functions that make it easier to control your vehicle. If you find yourself in an uncontrolled acceleration, there are much better options to take control of your vehicle: apply the brakes or put the car in to neutral. Your brakes are more than adequate to stop the vehicle and since basically every car sold has a rev-limiter, your stuck accelerator won't kill your engine if you pop it in neutral.

Car and Driver found that even a 540hp Roush Mustang only took 900ft to stop from 100MPH with both pedals to the floor. Most tests only took less than a couple hundred feet to stop: http://www.caranddriver.com/fe...

Your comment makes no sense, since reusing those frequencies for more efficient newer technologies (4G) will improve their network.

The reason that 2G has better signal quality than 3G in your area is that the 3G signal is overloaded. Since 3G phones will prioritize 3G signals over 2G signals (since they are more efficient and capable of more bandwidth) and most people have 3G phones, most phones are on 3G signals.

AT&T are in a bind right now (as are most other cell providers). More people are trying to use more data over wireless all the time, which means that their cell networks are getting overcrowded and way oversold. They need to add more capacity, but that requires either more RF bandwidth (necessitating new phones/devices to use the new frequencies) or they need to replace their current services with more efficient protocols that are more spectral efficient (moving to LTE). This is part of the latter. By reusing the bandwidth that is currently in use for 2G as 4G (or shift 2G -> 3G, 3G -> 4G), they can add more capacity to their network, thus improving the network quality for everyone (except those still using 2G only devices).

Yeah and it was like, what, +5 there a couple days ago. Did it ever get to +5 in January in Minnesota 20 years ago? It sure as hell didn't in northern ontario.

Hell in Minneapolis, it hit 50+ twice in January, 4 days over 40, and half the month so far has had a high above freezing. December was about the same. It has been quite the warm winter here. This change to more seasonable weather has been welcomed by me, especially finally getting some more snow.

I have Alltel data service as I live in a rural area where the only alternatives are 24-36Kbps dialup or 400-700k satellite. I pay about $60 per month and Alltel is "unlimited," however with the Verizon takeover I'm not sure how this will affect things. I typically get speeds between 400-800Kbps, but have gotten up to 1Mbps on occasion. If you want more information about the various services look at www.evdoforums.com. Note that like any wireless technology, the total bandwidth at the tower is shared by all clients and as more people use the service, the speeds go down.

Personally, I can't wait to move and get cable or DSL.
