Comment Re:"Knowledge-based" questions are really bad (Score 1) 349

This is why the method of answering "security questions" for resetting a password has been frowned upon in security circles for about 10 years now. For some reason there are still a lot of large businesses that haven't got the memo that with a little social engineering an attacker can find out enough about a person from public records, social media, etc to answer these questions in order to obtain a password reset screen. That's exactly how some high-visibility attacks occurred over the last few years, for example last fall when some celebs had their Apple accounts socially engineered and private (read "nekkid") photos stolen from their accounts.

The electric monopoly in my area does (or at least did) see solar as a threat to the status quo. They rolled out a pilot project to subsidize solar installations under some federal government program, but did so in a way that made it pretty obvious that they intended that the pilot project would fail. When it did, they were able to tell the media "well, interest in solar is extremely low, and based on how this project failed we are not going to roll out subsidized solar at this time (we *will* keep the unused federal dollars in a shady tactic but that's a different story)". It took another 5 years but they are now coming around but in the interim they were very anti-solar.

Comment Re:Good for him! (Score 1) 223

Perfect example of a Confusopoly. Make it just annoying enough so that the bulk of the people will just say "screw it" and the company makes a lot more money (or loses way less money than they would have).

Reminds me of the hoops that you used to have to go through to get rebates on electronics back in the 90's. It should have been simple: "fill out this form, cut the UPC code off of the box (making it impossible to return), wait 4-6 weeks, deposit the check". Unfortunately, a large percentage of the time there would be no check after 6 weeks, and the procedure to actually make the claim was annoying enough that most people said "screw it" and never pursued the issue, even if they remembered that they ever sent the rebate form in 2 months ago at all.

Comment Re:Commas matter. (Score 1) 88

No. The Oxford Comma specifically refers to a comma between the last two items in a series. "I went to the store for grapes, milk, and bread" versus "I went to the store for grapes, milk and bread".

The comma between the city name and the state is required; the additional comma after the state is usually needed for clarity when the city and state are used in a sentence.

Comment Re:Test string here: (Score 1) 399

Even if you are running homebrew's bash as your current shell, your command is just calling "bash" and not "/usr/local/bin/bash". I suspect that your PATH has /bin before /usr/local/bin. Try this instead:

env x='() { :;}; echo vulnerable' /usr/local/bin/bash -c "echo this is a test"

Comment Re:Proformance (Score 1) 370

The checksums don't really take up more physical overhead than a more traditional RAID + LVM setup, and performance is equivalent in my experience (albeit on Solaris 10 and not Linux). There is also the ability to turn on compression, which trades a little bit of CPU overhead for increased disk I/O performance. On a lot of workloads the difference can be dramatic.

If you are already comfortable with RAID + LVM, then I would wholeheartedly recommend ZFS for your main workstation. I would also recommend taking a look at FreeNAS if you are looking at building a network storage device. Snapshots, replication, ease of management are all ZFS strongpoints and ZFS is one of the things that I miss most about Solaris before Oracle bought them and priced themselves out of our datacenter.

Comment Re:jails and zones (Score 2) 29

When I was a sysadmin in our Unix team, I loved zones and championed them throughout our organization. In the span of a year, we migrated from scores of older, slower Sun systems into a blade chassis with 10 blades, each running Solaris 10 with up to two dozen zones each. Our big Oracle database used to run on a Sun E10000 system that was literally the size of full rack, and we moved it onto a zone on a T2 blade and gained a ton of performance. We even finally had a real DR solution, since the old solution was to manually mount the storage from the E10000 server onto a 280R that was 1/10th as powerful until we could get Sun out to fix the E10000. The new way was to setup SAN to SAN sync to our DR site, bring up the latest ZFS snapshot, and roll forward the transaction log.

Fast forward almost 10 years and Oracle has pretty much destroyed Solaris and priced themselves out of our data center. Even our most business-critical Oracle database is now running on RHEL now, and as soon as we finish migrating some production apps to RHEL VMs on Hyper-V, the Oracle hardware goes bye-bye. I have to manage some apps on RHEL and while I love working in Linux userspace again, I miss Solaris 10 for a lot of things. Stupid Oracle.

Comment Re:Amazon is right (Score 2) 306

That's Amazon's whole point. They have the data that shows that $9.99 is pretty much the sweet spot for "major label" authors, and 5.99-7.99 for all other authors. Publishers would make a lot more money if they priced the ebook at $9.99, but they have to protect their print sales so they generally price the ebook at $14.99 so that the $12.99 paperback looks attractive.

The other forgotten point in this discussion is that traditional publishing houses "cannabalize" their back catalogs and stop printing older paperbacks when they go out of print in order to promote their newer authors and/or new "bestsellers". Ebooks never need to go out of print so it doesn't make sense to do that, but they do it anyway. They drop a book for a while, and then reprint it right when the royalty deals with the author expires, extending the deal and their "ownership" of the copyright. It's pretty shady stuff.

That's the whole point. Every last one of these officers got above 90%, but the ones who (for example) got a 95% were promoted faster than the ones who got 93%. Answering one question wrong became at least a roadblock if not a career-killer, so they cheated to get 100%.

It like those "customer satisfaction surveys" that a lot of industries rely on. If you answer them correctly and accurately ("well they did the job adequately, no complaints so I give them 4 stars"), you are actually hurting the business or the customer service rep or the salesman. Anything less than "5-stars" becomes failure.

Comment Re:Libertarian nirvana (Score 1) 534

But the logical extreme of modern-day Libertarianism is Anarchism. We've pretty much tried every "-ism" on the books, both political and economic "-isms", and it's pretty clear from history that any "-ism", taken to its logical extreme, is a pretty bad thing that eventually collapses under its own weight and inevitable human greed and corruption. The best systems in place so far, are combinations that balance individual liberties with societies needs.
