US Scientists Predict Long Battle Against Ebola

I do like to drink my Columbian coffee, that according to you own link was probably indigenous to and first cultivated in Yemen.

You should try Colombian coffee instead!

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.

Red Hat Releases Ceylon Language 1.0.0

kybred Re:harmful constructs (159 comments)

For some reason, I always hate it when people choose an explicit

if (boolean == true)

rather than just

if (boolean)

I'm glad those people have to hunt for extra bugs ;)

Absolutely! If you give the boolean variable a good name it makes the code read logically:

if (thing_is_valid)
{
        do_stuff();
}

HP Discontinue OpenVMS

kybred VMS VERSION 4.1: (An official DEC memo) (238 comments)

VMS VERSION 4.1: (An official DEC memo)

Please stop submitting SPR's. This is our system. We designed it,
we build it, and we use it more than you do. If there are some
features you think might be missing, if the system isn't as
effective as you think it could be, TOUGH. Give it back, we don't
need you. See figure 1.

(slashdot whitespace filter won't allow the ASCII art middle finger graphic that should be here)
                                                        Figure 1.

Forget about your silly problems, let's take a look at some of the
features of the VMS operating system.

1) Options. We've got lots of them. So many in fact, that you need
      two strong people to carry the documentation around. So many
      that it will be a cold day in hell before half of them are used.
      So many that you are probably not going to do your work right
      anyway. However, the number of options isn't all that important,
      because we picked some interesting values for the options and
      called them...

2) Defaults. We put a lot of thought into our defaults. We like
      them. If we didn't, we would have made something else be the
      default. So keep your cotten-picking hands off our defaults.
      Don't touch. Consider them mandatory. "Mandatory defaults" has
      a nice ring to it. Change them and your system crashes, tough.
      See figure 1.

3) Language Processors. They work just fine. They take in source,
      and often produce object files as a reward for your efforts. You
      don't like the code? Too bad! You can even try to call
      operating system services from them. For any that you can't, use
      the assembler like we do. We spoke to the language processor
      developers about this, they think a lot like we do. They said
      "See figure 1.".

4) Debuggers. We've got debuggers, one we support and one we use.
      You shouldn't make mistakes anyway, it is a waste of time. We
      don't want to hear anything about debuggers, we're not
      interested. See figure 1.

5) Error logging. Ignore it. Why give yourself an ulcer? You don't
      want to give us the machine to get the problem fixed and we probably
      can't do it anyway. Oh, and if something breaks between 17:00 and
      18:00 or 9:30 and 10:30 or 11:30 and 13:30 or 14:30 and 15:30 don't
      waste your time calling us, we're out. See figure 1.

6) Command Language. We designed it ourselves, it's perfect. We
      like it so much we put our name on it, DCL - Digital's Command
      Language. In fact we're so happy with it, we designed it once
      for each of our operating systems. We even try to keep it the
      same from release to release, sometimes we blow it though. See
      figure 1.

7) Real Time Performance. We got it. Who else could have done such
      a good job? So the system seems sluggish with all those priority
      18 processes, no problem, just make them priority one. Anyway,
      realtime isn't important anymore like it used to be. We changed
      our groups name to get rid of the word realtime, we told all our
      realtime users to see figure 1 a long time ago.

In conclusion, stuff your SPR. Love VMS or leave it, but DON'T complain.

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."

FCC approves broadcasts that may jam GPS

Prior to the decision, representatives of the U.S. GPS Industry Council and prominent GPS manufacturers presented a report showing consumer GPS device began to be jammed at a power level representing a distance of 3.6 miles (5.8 kilometers) from the simulated LightSquared

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."
