Uh, no. They're actually way ahead of us. The F-35 was a response to the Su-27. They're two generations ahead of that now. The Sukhoi series is faster, better armed, better armored, more maneuverable, has a longer range, and basically kicks the crap out of anything we have. We'd better hope we don't get in a real war with the Russians or the couple of countries that can afford to buy their gear.

The Russians have done fantastic things with the Su-27 family. It is interesting to note that when the first prototypes of the Su-27 flew they badly underperformed. The Su-27 prototypes just could not match the relatively new F-15, which already held several world records. Rather than scrap it or built it as-is, the Russians went back to the drawing board and radically re-designed the plane. The result was nothing short than spectacular as the new Su-27 started capturing all sorts of records for time-to-height was capable of performed a variety of awe-inspiring maneuvers etc.

On a side note, one of the main weaknesses of the F-22 and US aircraft in general is their relatively short range. This is not a problem when you are operating in "small" countries and launching from carriers situated nearby but for any kind of operation over a large operational theatre (Russia, China, etc.) you depend on in-flight refuelling or the use of drop tanks. The former means that you have to protect those support assets and the latter nullifies your stealth capability. Stealth is sexy and handy when everything works out perfectly but it does impose its own limits and problems.

I would also be willing to bet that maintenance and repairs on Russian aircraft would be much simpler and cheaper, which matters in a real confrontation.

Anyone who dismisses the capability of the current crop of Russian aircraft, particularly when in the context of potential conflicts, is being disingenuous at best or has no idea what they are talking about.

+ - Dark Matter May Not Be Completely Dark

StartsWithABang writes: If you take two clusters, groups, or individual galaxies and collide them together, you'd expect the stars to pass through unperturbed, the gas to experience friction, slowing down and heating up, while the dark matter, if it's truly collisionless, will do the same thing as the stars. But if there's a tiny frictional force at work on dark matter, it, too, will slow down a little bit. A team looking at 72 groups and clusters saw no effect of slowing down, but then on the 73rd one, they saw a separation between the mass reconstruction and the stars. Is this the first sign of dark matter's interactions, or is it simply an astrophysical effect, or maybe even a fluke? A good recap and rundown of what we're looking at to the best of our knowledge.

... That is an advertised 18 hour battery life on day one with a brand new device. That means you'll probably be lucky to get 12 hours a day in a year or two, since rechargeable batteries tend to age poorly. By comparison, the upcoming Pebble Time advertised a week of battery life for the base model, and ten days for the Steel version.

My Garmin Fenix 2, which is an outdoor sports watch, has an advertised battery life of up to 5 weeks in watch mode, 50 hours in 1/min GPS mode and 20 hours in 1/15s GPS update mode. It has everthing (GPS, barometer/altimeter, compass, thermometer, plethora of built-in sports tracking modes, smart notifications from /any/ smartphone) in a standalone package. Granted the hockey-puck design will only appear to those that like diving watches, which works just fine for me.

Your mode of life will be changed to EBCDIC.
