I am not even sure if your comment is on topic, but I recall that RBAC is basically Sun's answer to sudo. As usual, instead of adopting in a well known, well liked, and well understood open source program into Solaris 8, Sun came up with its own "RBAC", which only works on Solaris and barely anyone used it.

Your comment reminds me the old Soviet joke about a director of a kolkhoz, who during an important meeting announced: "I have two news for you, one good and the other bad. The bad news is that we lost all crops and we will have to eat shit all of the next year. The good news is that we have plenty of shit!"

I was a college Solaris administrator from 1999 to 2007, and we stopped buying new Sun machines (mostly desktops, and some low end servers) at around year 2000, which can give you an idea how non-competitive they were in terms of hardware price-performance. And around that time, Intel Xeon was already slaughtering SPARC in CPU benchmarks like spec int/fp. Some have speculated that Sun's brand new UltraSparc III was briefly faster than intel around the year 2000 or so, but it took Sun like two years to start shipping those in significant numbers, and by then AMD/Intel left them in dust again.

Apple was always about FUD or making ridiculous marketing claims. I recall how in 1998, when they came up with the G3 PowerPC based computers, they were making the ridiculous claim that 233MHz G3 in an iMac was faster than 400MHz Pentium II, even though the claims were not based on some real world usage experience or benchmarks like spec int, but on some obscure Photoshop based benchmark if I recall that correctly. By the time Apple started using the G4 processors, claiming to be faster than Intel was not enough. Now they claimed that G4 is a supercomputer processor. Then couple of years later they announce the switch-over to Intel.. surprise surprise.

Granted, in the more recent times Apple hardware has usually been top notch, but companies will always have a need to spread marketing FUD against the competitor products..

Well, that shouldn't be an issue for 802.11ac or 802.11n. But like I mentioned in an other post, any AC router rated faster than AC1750 or AC1900 is overkill. You can make an argument that the two-stream AC1200 will suffice for 90% of households, since less than 5% or so of people have three stream capable wireless adapters.

It only would have MU-MIMO enabled devices, and they started hitting the market only this summer. So if you have three single stream AC clients and an AC17500/AC1900 three stream access point, then they all could talk it at once. However, there is still an issue with MU-MIMO, because MU-MIMO allows simultaneous clients only for uploads to the router. It won't help in situations one MU-MIMO client transferring files to another MU-MIMO client connected to the same radio on a AC.

The 1300Mbps is a scam figure because it's industry convention to report the layer 2 data transfer rate, but at that layer there is a lot of chatter dealing specifically with the physical link quality, which can be substantial with wireless. So indeed, in most cases you can take the number, then divide by two. That's the TCP/UDP data rate you will see in the best case scenario.

Moreover, 1300Mbps is the figure for the three-stream capable devices. But what's the percent of clients with three stream wireless adapters? About less than 5%?

Comment Re:Buy APs, not Wireless Routers (Score 4, Informative) 77

Yes, but why should I pay for all that routing functionality when I will turn it off anyway?

You don't have any other alternatives, at least when we're talking about home-network class hardware. The market for plain ACs is so thin, that it's much easier and cheaper to actually buy a wireless router.

Comment Re:Every paper must come with the code and data, b (Score 1) 213

That's just a small area of economic research. A lot of studies work with publicly accessible data after it had been 'massaged' one way or another. That's because typical census/survey data sets come in multi-gigabyte mess of numbers, while a typical research question needs to operate on a small subset or a transformation of that subset. How the researcher gets from the raw survey data file down to the data set he is analyzing is not always clear. Also, the statistical codes, which are not always trivial.
