New LLVM Debugger Subproject Already Faster Than GDB 174

kthreadd writes "The LLVM project is now working on a debugger called LLDB that's already faster than GDB and could be a possible alternative in the future for C, C++, and Objective-C developers. With the ongoing success of Clang and other LLVM subprojects, are the days of GNU as the mainstream free and open development toolchain passé?" LLVM stands for Low Level Virtual Machine; Wikipedia as usual has a good explanation of the parent project.

Yes, I agree totally. Having these results floating around uninterpreted by someone who really knows the science is just a recipe for silliness, but also some real harm could come if people jump to conclusions.

At one point, our obstetrician ordered up a "routine genetic screening" while my kid was in utero. I guess he was looking for Downs or something where the markers are well-known. What came back was a report of a marker - a "backwards" chromosome, and a cryptic one-liner about possible dire stuff and a reference to an academic paper on which the marker identification was based. Our obstetrician, a very experienced guy, couldn't tell us anything about what dire stuff we might be facing, or what the probability was, or what it all meant. He noted that according to the paper, if one of the parents had the same marker and was fine, then the probability was very high that the marker was benign. We also contacted the geneticist who performed the test for more information and counseling, and she had no further information about the meaning of the results. So we tested both of us parents (not cheap!) and mine came back with the same marker. Big sigh of relief -- no, no particular reason to consider aborting the fetus.

In the interim, we tracked down the researcher who wrote the original paper. Google and email are wonderful things. The researcher turned out to be a nice post-doc at Columbia Presbyterian. She couldn't tell us what dire consequences we might be facing or their probabilities, either. I don't think she'd ever been anywhere near a clinical situation. She had only published a paper noting the correlation and indicating that this might be a fruitful area for further research. She was quite surprised that a commercial genetic testing company was using her results as the basis for a test used for routine genetic screening.

This is very young science, folks. This is just one tiny example, and there are a lot of genes! It's going to take decades to sort through all the data we already have to figure out what it means. Doing this over the counter now is really jumping the gun.
