Apple Fixes Shellshock In OS X

kybred Re:Why isn't this auto-update? (174 comments)

I downloaded and installed this update. It updates bash to version 3.2.53(1), but a patch to version 3.2.54(1) is available on gnu.org. I'm guessing that there will be more updates since additional issues with the parsing in bash have been (are being) found.

Security Collapse In the HTTPS Market

kybred Re:So offer a cost effective replacement (185 comments)

Which kinda suck for use as a recurring payment method.

No they work quite well. When you setup the 'one-time' use number, you specify that it is for recurring charges. When the first charge hits it, the number is bound to that vendor. Any charge to that number from a different vendor will be rejected. This can cause a problem for some vendors that change card processors after you've set one of these up.

What about 3-phase power for lighting? When you full wave rectify 3-ph you don't get the 0 volt valleys in the wave. Of course, we're not going to re-wire all our houses for that.

Ask Slashdot: Who Should Pay Costs To Attend Conferences?

kybred Re:Your employer (182 comments)

Often the conferences have sessions on lessons learned, best practices, etc that can really help. The *one* time I went to a conference I made sure to bring back lots of notes on the sessions and to spread them out to my co-workers. They didn't get to go to the conference, but they still got some benefit from it. If management sees that kind of thing, they might be more willing to send someone, maybe rotating the person that gets to go.

Toyota and Tesla May Work Together Again

kybred Re:I hope Toyota doesn't write the software (51 comments)

The EE Times article is from 2013. Barr analyzed the source code and found numerous problems:

Having spent more than 18 months going in and out of the secure room to study Toyota's code, Michael Barr, CTO of the Barr Group, put together an 800-page report analyzing the 2005 Camry L4's software. On the witness stand, he walked a jury step by step through what the experts discovered in their source-code review. According to Barr's testimony, that review revealed:

        Software bugs that specifically can cause memory corruption

        Unmaintainable code complexity in Toyota's software

        A multifunction kitchen-sink Task X designed to execute everything from throttle control to cruise control and many of the fail-safes

        That all Task X functions, including fail-safes, are designed to run on the main CPU in the Camry's electronic control module

        That the brake override that is supposed to save the day when there is an unintended acceleration is also in Task X

        The use of an operating system in which there is no protection against hardware or software faults

        A number of other problems

Single bit flips can also be caused by memory corruption, not to mention tasks crashing.

Toyota and Tesla May Work Together Again

kybred Re:I hope Toyota doesn't write the software (51 comments)

Pretty sure those runaways were caused by morons who put their floormats over the accelerator, not software.

Pretty sure they weren't (at least, not all of them).

Having spent more than 18 months going in and out of the secure room to study Toyota's code, Michael Barr, CTO of the Barr Group, put together an 800-page report analyzing the 2005 Camry L4's software. On the witness stand, he walked a jury step by step through what the experts discovered in their source-code review.

...

Barr testified that the source-code review indicated "both that task could die by the memory corruption, and that also that one of side effects of that would be that this -- for example, that task died, that many of fail safes would be disabled." But is it possible to prove that the experts' discoveries in that cloak-and-dagger source-code room would manifest themselves in a moving vehicle? How do we know how a car might react to malfunctions or an outright failure in Task X?

...

However, we have confirmed in other vehicle testing that I'll talk about later, that if the incident begins with the peddle, [sic] brake peddle [sic] pressed at all, even lightly then the unintended acceleration will continue, potentially, forever unless the driver tries the risky thing of letting go of the brake while the car is driving away with him.

Oregon Sues Oracle For "Abysmal" Healthcare Website

kybred Not all states failed (212 comments)

Here's a success story about Kentucky's Kynect Exchange.

They need not have worried. Over the past year, Kentucky’s health care website has proved to be a huge success. More than a half-million Kentucky residents have signed up for the Bluegrass State’s version of Obamacare. A majority of Kentuckians approve of it. That this has happened in a deeply red state is unexpected but hardly an accident.

The lines of code immediately after the second 'goto fail;' up to the 'fail' label are unreachable. There is no label or closing brace after the second goto fail, so how would it get executed?

Least-cost routing threatens rural phone call completion

kybred kybred writes  |  about 2 years ago

kybred (795293) writes "Rural landline users are increasingly having problems with incoming calls not completing or being dropped. The culprit may be the bargain long distance carriers penchant for 'least cost routing' combined with the conversion of the Universal Service Fund to the Connect America Fund.
From the Fine Article:

"Rural phone companies are the victim here,” Steve Head says. “They charge a higher rate to terminate calls as it costs more for them. Shoreham Tel gets beat up because everyone calls them and says something is wrong with your system, but it’s not. We’ve been through all of their lines and equipment and there is nothing wrong with it; it’s the least-cost routing carriers."

Continuing Problems with Dallas Emergency Dispatch

kybred kybred writes  |  more than 5 years ago

kybred (795293) writes "The new emergency dispatch system in Dallas, Texas has not been getting very good reviews.

From downtime due to operator error

Friday's problems began about 7:30 a.m. when the dispatch system went down. While the system was offline, 911 operators wrote information on cards. Runners took those cards to police and fire dispatchers, who then sent out emergency workers. The system came back online shortly after 10 a.m.

To today's problems with a virus that has been found in the system.

The latest update says that it is still down."
