Carquestions investigates the inside story behind Toyota’s recall involving a stuck gas pedal. Its being reported that it could be the most expensive recall in history. This could also be a problem for other manufacturers who use similar systems if it turns out to be a software bug or shared common part. This is a good example of how expansive and expensive a recall can be when you use common parts. The parts company that made the gas pedal, CTS (a Canadian company) has supplied Ford, GM and Chrysler among others.

ABSTRACT
Advanced Topics in Programming Languages: JSR-305: Java annotations for software defect detection
This talk will describe the current status of JSR-305, Java annotations for software defect detection. This JSR will define several standard Java annotations for properties such as @Nonnegative and @Nonnull that can be used to document your design intentions in a way that be interpreted by multiple software tools (such as FindBugs and IntelliJ). In addition, the talk (and JSR) will discuss the need for inherited and default JSR-305 annotations and propose a way to provide them.
We’ll also discuss our proposal to define meta-annotations, that allow…

The Apollo 5 mission was intended to test the Lunar Module in a space environment, in particular its descent and ascent engine systems, and its ability to separate the ascent and descent stages. The descent engine would become the first throttleable rocket engine fired in space.
The mission was also intended to perform a “fire in the hole” test – as depicted in the mission’s insignia – whereby the engine of the ascent stage would be fired whilst still attached to the descent stage. This would simulate the conditions experienced in an abort during descent to the lunar surface.
It had been planned to launch Apollo 5 in April 1967 and so delivery at the Cape was hoped for around September 1966. But delays kept occurring. Although the lunar module was fully designed, there was trouble fabricating the custom made parts. The all important engines were also having problems. The descent engine was not burning smoothly and the ascent engine was having fabrication and welding difficulties.
The launch vehicle for Apollo 5 was the Saturn IB, a smaller rocket than the Saturn V but capable of launching an Apollo spacecraft into Earth orbit.
On 22 January 1968, eight months after the planned launch date, Apollo 5 lifted off just before sunset. The Saturn IB worked perfectly, inserting the second stage and LM into a 163 x 222 km orbit. The Lunar Module separated 45 minutes later, and after two orbits started a planned 39 second burn of its descent engine. This was curtailed after four seconds by the onboard guidance computer, which detected that the engine’s thrust was not building up rapidly enough. This was due to a software bug; the propellant tanks were only partially pressurised, and it took longer than the programmed four seconds to reach full acceleration.
The ground controllers moved to an alternate plan. They turned off the guidance computer and started an automatic sequence programmed into the onboard computer. This fired the descent engine two more times. It then performed the “fire in the hole” test and another ascent engine burn.
After four orbits the mission was over, and the two stages were left to decay into the Pacific several hundred kilometres southwest of Guam on 12 February.

Pretty weird iPhone bug
Error : It is the Deviation from actual and the expected value.
Bug : It is found in the development environment before the product is shipped to the respective customer.
Defect : It is found in the product itself after it is shipped to the respective customer
"Software bug" is nonspecific; it means an inexplicable defect, error, flaw, mistake, failure, fault, or unwanted behavior of a computer program. Other terms, e.g. "software defect", or "software failure", are more specific.
While the word "bug" has been a part of engineering jargon for many-many decades; many-many decades ago even Thomas Edison, the great inventor, wrote about a "bug" – today there are many who believe the word "bug" is a reference to insects that caused malfunctions in early electromechanical computers.

THERE IS A BUG WITHIN LOW LEVEL SOFTWARE THAT WILL AFFECT MACHINE ON THE 20TH OF OCTOBER.
If there is, it’s the first I’ve heard of it. However, if the world didn’t end after Y2K, I think we’ll survive Y2k10.

ABSTRACT
I’ll talk about some of my experience in using and expanding static analysis tools for defect detection. The FindBugs tool developed at the Univ. of Maryland is now being widely used, including inside Google.
I’ll give an overview of FindBugs, show some of the kinds of errors we routinely find in production code, discuss the methodology we use for enhancing and expanding FindBugs and some of the recent additions to it, discuss ways of incorporating FindBugs into your development process (such as being able to get a report of all the warnings introduced since the last release of your software), and talk about the future of static analysis,…

like what above said,u know,there are always latest microsoft bugs,u have to fix them over and over again,so are there any FREE software which can discover the bugs and fix them? thx
Do you have auto windows updates turned on. You really should.
Where can I download free, virus/bug free software, that uses greenscreen/bluescreen + effects, off the internet?
I would suggest one of the following as possible tools:
Wax
Blender
T@BZS4
Blender is the best, but also the most complex. All are free.
Community guidelines at Yahoo! Answers forbid me from posting a link here to a useful website that I run. However I suggest a quick look at my profile might help…
Thanks.. Freevideoman
