Yes. We use PowerChute everywhere; it's a good product.

But, at least in a production system, you still should be doing regular "real" failover tests to ensure that what is supposed to happen does really happen. For example, a common problem is a sequence like:

- Power fails, UPS predicts 20 minutes of runtime;
- Servers are set to shut themselves down when 5 minutes of runtime remains;
- Fifteen minutes later, the servers start their shutdown sequences;
- The increased CPU and disk activity from the shutdown increase the power draw, causing the battery to empty and all power to be cut 90 seconds earlier than expected.

Another issue is that software added during a system's lifetime can cause a server that took 180 seconds to shut down last year to now require 240 seconds.

Either issue can mean you wind up with servers that powered off with a 90% completed shutdown.

The only way you'll discover these kinds of problems is to actually simulate a real power fail once in a while.

Really, a $150 investment to protect your $500+ computer is more than worth it.

Don't forget to add the cost of replacing the UPS battery every year or two. Plus the time to setup and regularly test the fail-over and auto-shutdown.

FWIW I generally use a UPS on the servers and firewalls, but not on any of the clients.

+ - Canadian Police Recommend Ending Anonymity on the Internet-> 1

Submitted by Anonymous Coward
An anonymous reader writes "Michael Geist reports that last week the Ontario Provincial Police, one of Canada's largest police forces, recommended legally ending anonymity on the Internet. Noting the need for drivers licenses to drive or marriage licenses to get married, the police suggested that an Internet license that would reveal all users is needed to address online crime. The Canadian Supreme Court strongly endorsed a right to anonymity earlier this year."

The previous record of 17 patches is from 2011. All of the upcoming patches fix serious security problems under topics of remote code execution, elevation of privilege, security feature bypass, information disclosure, and denial of service. The affected products are Windows, Internet Explorer, .NET, Office and Exchange. Karl Sigler, threat intelligence manager at Trustwave, explained that one of the critical bulletins may also address the Windows OLE remote code execution flaw."

BALR *,13 to you, sir.

surely it was

        BALR 15,0
        USING *,15


PS: I blame this to be the start of the enormous overuse of #define in subsequent decades, as most people thought it was cool to equate R15 to 15 (etcetera) and then write the above as

        BALR R15,R0
        USING *,R15

leading to the endless nested equating we get in modern C and C++.

PPS: for the worst such mess ever created, does anyone else remember the COBOL "ALTER" command?

Using a text editor to write code for a device like an iOS device, that simply displays the weather or a stock price is so ... 1960s?

Well -- 1970's maybe. 1960's were more about drum storage and all that. Even in the early '70s, the 029 keypunches didn't let us correct typos -- you had to hold the "dup" key down to duplicate the bit you got right, and then carry on keying from where the mistake started. The 129's were much better, as they only punched the card after you finished the whole line.

Although come to think of it, I did write a nice simple weather app in 360/Assembler for a class in 1974.

+ - 2015 Corvette Valet Mode Recorder illegal in some states->

Submitted by innocent_white_lamb
innocent_white_lamb (151825) writes "The 2015 Corvette has a Valet Mode that records audio and video when someone other than the owner is driving the car. Activating the Valet Mode allows you to record front-facing video as well as capture audio from within the car so you can help keep your Corvette safe when itâ(TM)s in the hands of others.

Well it turns out that recording audio from within the car may be considered a felony in some states that require notice and consent to individuals that they are being recorded and now GM is sending notices out to dealerships and customers alerting them to this fact as well as promising a future update to the PDR system."

Hello fellow pedant.

You have to extend the planes into the plane of the camera view.

When the front and back planes are extended it is entirely possible for the camera view plane to be perpendicular to both. In fact, it would be impossible for it to be perpendicular to only one since you pointed out that the front and back planes are parallel.

True. Mea culpa.

What I was objecting to was something else, implied in parent post, to the effect that the lens axis lay on the both the front and back planes of the phone at the same time. But I expressed it poorly.
