Mac Pro first impressions

I received my late 2013 black cylinder Mac Pro last Monday. I ordered the 6-core model with D700 GPUs, since the higher-core models can’t Turbo boost to the full 3.9GHz the 4-core and 6-core ones can, and thus for most poorly-parallelized apps will underperform. I had to get a Promise Pegasus J4 with a pair of Samsung 840 Evo SSDs to hold my files, as I need nearly 2TB to do so and that is not available on the internal SSD, and it would be a shame to hobble this machine with spinning rust.

Some notes I have not seen in the many reviews sloshing around the Internet this far:

  • It is not actually black, rather a dark metallic gray, the color of hematite.
  • The TOSlink digital optical out is now capable of 192kHZ/24 bit audio, whereas the old Mac Pro was limited to 96 kHz. Unfortunately, it is very hard to find POF cables and DACs that can reliably sustain that data rate.
  • It is dead quiet compared to the old Mac Pro, and even my work iMac.
All in all, a remarkable engineering feat. A HP Z820 may have more memory capacity, expandability and total horsepower in its BMW-designed case, but Apple is the one pushing the envelope in terms of design.

Externalities again

I just wasted half an hour of my life on the phone with my credit card company’s fraud department, as someone attempted to buy expensive tickets from an airline in Panama. Most likely my card number was compromised by Target, although it could also be due to Adobe.

It is actually surprising such breaches do not occur on a daily basis—the persons paying for the costs of a compromise (the card holder, defrauded merchants and their credit card companies via the cost of operating their fraud departments) are not the same as those paying for the security measures that would prevent the said breach, a textbook example of what economists call an externality. There are reputational costs to a business that has a major security breach, but they are occurring so often consumers are getting numbed to them.

Many states have mandatory breach disclosure laws, following California’s example. It is time for legislatures to take the next step and impose statutory damages for data breaches, e.g. $100 per compromised credit card number, $1000 per compromised social security number, and so on. In Target’s case, 40 million compromised credit cards multiplied by $100 would mean $4 billion in damages. That would make management take notice and stop paying mere lip service to security. It might also jump-start the long overdue migration to EMV chip-and-PIN cards in the United States.
