Comment Re:LED Light Bulbs (Score 1) 479

Most LED degradation is due to heat. They still get quite toasty (of course nowhere near an incandescent). They also share the linear light dropoff as they age with fluorescent bulbs. However they don't have the warm-up issues of a fluorescent.

Thats the crux of it. The applications were spammy, brought nothing to the table except for a few pictures at $0.99. You could churn out 100 such applications in a day, and some people got close to that rate.

If Apple adjusts their policy towards habitual application spammers (have you seen the Games section?), it would also solve the problem. But its easier to just target soft porn.

Advertised speed class is different from actual quality. For instance, many off-branch CompactFlash cards do not support DMA - they are supposed to by the specification, but since little end equipment actually used DMA modes until very recently, very few people noticed. This is the same for SPI mode in SD cards (though not a requirement in microSD).

Well TPM is a relatively open standard. If you can find a fundamental flaw in the implementation, more power to you. That would be breaking TPM wide open, if accessible from the outside. This is akin to someone figuring out that all door locks from vendor X will open with a master key. Physically disassembling an IC, and taping one of its logic lines is specialized work (even in hardware engineering), as done in the TPM case. This attack is akin to someone cutting down your door with a chainsaw, cutting open your door lock, and making a duplicate key from looking at the pins.

You want contained hot aisles or contained cold aisles to maintain maximum efficiency. You want managed airflow.

Its perfectly ok for the hot aisle to be at 100+F. Its also perfectly ok for the cold aisle to be at the mid 70s, as long as there is no stratification or leakage (top of the rack should be within limits). What you want to see is offline CRAHs or VFDs installed in the CRAHs throttling back their airflow.

I work at a company which specializes in monitoring and helping customers improve their capacity and energy use. By placing air where it needs to go you can both cut costs and improve capacity. Sadly, very very few datacenters are run with the efficiency and managed airflow in mind (people even put perforated tiles in the hot aisle!). If you have containment, then you're 95% of the way there. Another more modern option is liquid cooled racks, or in-row cooling (APC Pods and the like).

I think both of us share the similar approach to style, which is in some ways minimalism. I use both Thinkpads and Macs, and both share the same design ideas. Both utilitarian, without gaudy mirrors or trendy glowing lights. Both are unobtrusive to using the actual computer.
