That is the question. Although this failure occurs, relatively speaking rarely, I'm not so sure that Toyota has determined the root cause(s) of the failure. The number of combinations of inputs are huge, and the subset of those that can cause catastrophic failure is small. How can we be even reasonably sure that they have isolated those causes? In my opinion, as a software engineer with almost 30 years experience in embedded, real-time, large-scale, and high-reliability systems design and implementation I have to believe that this is not a coding error per se, but a design flaw in the system itself. Properly designed, safety critical systems will "fail safe". This is not happening. So, who knows if the changes made will make the system, over all, more or less safe? Without a complete model and access to ALL source code and the tool chain used to implement these systems, one cannot say.
Bottom line? There is no way to say that updating the software/firmware will make the system more, or less, reliable. Personally, I think it's a crap shoot. So, do the update. The results probably won't be more dire than the current situation, and may reduce the solution set for catastrophic failure scenarios.
I have found that some of the newer ethernet-over-powerline adapters work quite well in the home for this sort of bridging, and can handle up to a couple hundred mbps. I have a 200mbps Netgear pair that I use to bridge my home-office network to my wife's home-office network that is on another floor and other end of a long house.
He probably could have made serious $$ with this tape, but didn't. Hopefully it was out of respect for the Challenger crew. If so, I applaud this person as a man of ethics.
Just because a significant portion of Linux and open source software is developed pro-bono by the contributed efforts of many people, it does not mean that no one is paid to develop this body of work. Monetary contributions are made, people are paid so they can make a living. This is good and correct. Folks who think that all efforts toward the public good should be done for free should get their heads out of their nether regions.
The NY Times is shooting itself in the foot, big time. Readership == advertising revenues. Charging to read == less readership (they will lose me for sure) == less advertising revenues == lower profits == bigger losses == no more NYT.
I would tend to agree that discrete structures is most useful for general purpose programming. However, if you plan on getting into the lucrative field of high-preformance investment programming (financial derivitives, real-time trading algorithms, etc) then the second would be a good choice. So, take the first one first, and if you can, take the second one later. Both will stand you in good stead.
FWIW, I used to write risk-analysis software for the options trading industry. We used a lot of calculus and differential equations in computing the theoretical pricing and risk factors of derivatives. However, before that I did about 20 years developing real-time manufacturing systems software and knowledge of discrete structures, formal logic, and proofs (to detect race conditions in complex systems) was most useful there.
Any bets on how long it will take to crack this ill-considered DRM scheme? My guess is certainly less than 6 months from release. Why so long? Because they are likely using more robust encryption and it will take awhile to find the holes in it. In any case, the studios will still have to release content on DVDs for a long time, and that means it is less than 1 hour from release to wide availability on the internet... So, what does this buy the studios, content creators, actors, et al? More $$? NOT! Wider distribution of their work? Right... Can't get wider than universal access, which is what we pretty much have now. Such narrow-minded, short-sighted mavens of moronity should just shoot themselves and put us all out of their misery!
People purchase music they like and then play it relatively frequently. Movies are quite different. Most of us will watch a particular movie once, and possibly twice or three times if we really like it. Kids videos are somewhat different in that they (the kids) tend to want to watch stuff they like over and over. Until the movie industry realizes that they can sell more and make more by significantly lowering the price of movies, they are never going to overcome "piracy" and illegal sharing of their IP. FWIW, most of the movies my wife and I purchase are in the $5 remainders bin. If feature movies sold for under $10 USD each, there would be little or no financial incentive for pirates, and it would be more cost-effective for people who share ripped, substandard, copies to simply purchase the product with official media and quality.
A lot of IT support positions require on-call duties. I've been there, done that myself. However, if one is expected to be responsive during off-hours then two things need to be considered. One is that there should be some compensation for being available at all hours. Not at full salary/pay levels, but some financial incentive for those willing to be inconvenienced at the worst possible moments. Second, when the phone rings, whether a site visit is required or not, the overtime pay clock should start and not end until the call is complete, including travel time to/from the site if necessary. After all, if your support is a 3rd party person/organization, then they would properly insist on a retainer fee up front to cover the on-call clock for the period of the contract, and work clock time gets billed separately. Why should an employee who is expected to put in a regular shift on-site be treated any differently?
In the 70's and 80's, HP in Cupertino used to send engineering drawings (as microfich) to a facility near Santa Cruz, on the other side of the Santa Cruz mountains using carrier pigeons. It was faster and more reliable than using motorcycle courier, and in those days the Darpa-Net wasn't fast enough for the purpose. CPIP - Carrier Pigeon Internet Protocol - good bandwidth, not so good latency, though a packet ACK is easily accomplished with a phone call...:-)
I wonder how long it will be before all of this bozo's personal information will be scraped from the web and posted for all and sundry? I give it about 3 days, tops.
Caveat Emptor! And the labels are wondering why we aren't buying into their dren! They deserve to go out of business. I used to purchase over $1000 USD / year in CDs, but any more the only CDs I purchase are directly from the artists at their concerts or workshops.
This is just another example how big media is trying to circumvent the right of first sale. They would prefer that you aren't purchasing the product, but rather a non-transferable license to use the product. This effort must be thwarted at all costs, or pretty soon we won't be able to "own" anything...
It is so sad that someone who is so clueless is in such an influential position, and for life no less! Anybody else in favor of term limits for federal judgeships?
This is a good example of the razor blade principal. Most of these manufacturers make more off of consumables and add-ons than they do with the prime unit. Pretty soon these camera manufacturers will make it so you need to purchase their flash drives as well as their batteries, at a premium of more than double what you'd pay for the same thing from any reliable 3rd party. That was certainly the case of the backup battery I purchased for my Casio camera. Theirs was over $45. The replacement from a major battery manufacturer was about $15, shipping included! As far as I can tell, there is about zero difference in their performance and time-to-discharge or recharge. I'd guess that the replacement only differed in the label. They probably manufactured the OEM batteries as well.
I don't let anyone use my laptop. Period. I'd almost rather practice unsafe sex. The chances of getting a "terminal" infection are probably about the same, and sex is a lot more fun!
Say goodbye to Java. This is sounding its death-knell. Time to move the Eclipse project to some other software platform I think (if only that were feasible).:-(
After that mind-twisting season 2 finale, I was REALLY looking forward to another season! My opinion of this show is that it was one of the most well-written series of the genre, and it explored a lot of important social issues, such as the morality of Power. Anyway, I was hoping to see what John did with his emerging leadership skills and personal charisma.
As Bruce Schneier would say, this is simply Security Theater. As others have pointed out, making ones code "compliant" is trivial, and worthless! As a professional, and published, software engineer with almost 30 years experience in the development of large-scale, high-availability distributed systems, I think that this is absurd in the extreme, and it takes focus away from techniques that can truly improve system reliability and security.
I got a StarTech InfoSafe enclosure. Has both eSata and USB 2.0 external connections. Don't know off hand if it handles both sata and ide drives. I'm using sata-2 drives.

Just say NO! to H264.

Heck, I got my grandkids the Lionel Area 51 train set for xmas a few years ago. It had a glow-in-the-dark UFO following it!
I can just see the adv. on eBay now: Slightly used, somewhat radioactive train set. Glows in the dark! Minimum bid $50.00

Yet another reason to boycott Sony. The cassette deck I purchased about 5 years ago is probably the last penny that Sony will ever get out of me.
