when I think NVM I think of Non-Volatile Memory something like RAM that doesn't go blank when you hit the power button

This is the "Persistent Memory" device class. See e.g. this article for a nice summary of the status quo: https://lwn.net/Articles/636096/

> but when you were a few years out of college, did you have 3-6 months of salary saved up? I certainly didn't.

Actually, I did and it was a top-priority for me.

IMHO the data transfer rate is the important info:

  First 3.5 GB : 196 GB/s == 7/8 of 224 GB/s
  Last  0.5 GB :  28 GB/s == 1/8 of 224 GB/s

"When the GPU is accessing this segment of memory, it should achieve 7/8th of its peak potential bandwidth, not far at all from what one would see with a fully enabled GM204. However, transfer rates for that last 512MB of memory will be much slower, at 1/8th the card's total potential." http://techreport.com/review/27724/nvidia-the-geforce-gtx-97...

I'ld love to see bug voting on Open Radar. Identifying the most important bugs would become much easier.

Soon it will support Spotlight. See https://openzfsonosx.org/wiki/Changelog#1.3.1-RC5

The "stopping privacy" argument could be a red herring.

"And if you're still running OS X Mavericks or below then why not try it out?"

In other words: "insecure" or "unstable" - choose one.

I'm all for upgrading to Yosemite, but this is a problem.

Haswell-E is Intel's high-end consumer CPU series and there's nothing wrong with that. However, only buy it if you regularly use software that is able to utilize that many cores/threads.

The dual-core CPU you are looking for is called the "Pentium Anniversary Edition: Intel Pentium G3258" and was released in July.

Support for the CPU code names in -march is a simple but really useful change:

   -march=nehalem, westmere, sandybridge, ivybridge, haswell,
   bonnell, broadwell, silvermont

Also this:

   -mtune=intel can now be used to generate code running well
   on the most current Intel processors, which are Haswell
   and Silvermont for GCC 4.9.

(Caveat: I haven't tried this myself!) Here's the analysis and an experimental patch from @i0n1c for the 64bit version of Mavericks' Security.framework (32-bit remains unpatched): http://sektioneins.de/blog/14-02-22-Apple-SSL-BUG.html

That's why you should use ssh-agent and protect your private key with a passphrase.

IMHO it's interesting that they continue to use CF cards in their pro bodies. Some expected the switch to smaller SD/SDHC/SDXC cards.

But I wonder why they decided to announce the 1D X so early? I suppose this will hurt their pro body sales for five months. (The new body will not ship before March 2012.)
