overall, what I really want to know is, _why_ does it work on windows? Or what are we doing differently on Linux so that it doesn't work? If anybody has any idea on how we could dig into this and figure it out on this level, this would probably allow us to get closer to the root cause? no?

Hi Zhengyang, Do you mind sharing _why_ you need the intrinsic declarations to stay around? It is possible that there is a better way of solving your problem. Thanks! -- Sanjoy

This might be off topic, but if R-core development ever moves to git, I think it would make sense to have its own git service hosted by a university, rather than using github or gitlab. It is possible via https://gogs.io/ project. Just for the record. Best, -m

I noticed just now that package.skeleton() produces R files in which the function names are escaped with backticks. ?Quotes says that "The preferred quote is the backtick (`)", but I don't understand _why_ this is preferred. ?formula gives some clues but points out that there are no guarantees that formulae using non-syntactic names such as `like this` will be accepted. What exactly do backticks do that single or double quotes don't? Where do I look for documentation on this? -- Robin Hank...

...ines identical to the one above and finally: the_last_package_I_installed_yesterday.rpm all the other rpms in reverse installation order I've seen via google that this should mean there is a damaged rpm database and it should be rebuilt with one or two command, however: 1) how can I find out _why_ the damage happened? 2) what are the right command and options to restore the database? The examples I've found are 5+ years old, so I'm not really inclined to run them as they are. TIA, Marco

I know the 'print command' directive is disabled when printing via CUPS, the man page says so. Can anybody explain _why_ this is the case? My situation: I'm administering a package that shares a server with other applications. This proprietary unix package needs some help printing with the layout etc. so various sed/awk scripts need to take place before printing. This has been running using a print command in s...

But the commit message says nothing about _why_ it is needed, so I cannot guess. I would very much avoid it however. Is it just an optimization? Paolo

Anyone interested in _why_ un*x systems use this structure, take a look at the FHS (Filesystem Hierarchy Standard) project at http://www.pathname.com/fhs/ A lot of it has to do with managing networks of machines in a professional environment, which is why it seems pointless to a single workstation installation for a hom...

Dear LLVM community. I have a function pass. This pass will insert a llvm intrinsic function prototype (llvm.memset.p0i8.i32) to the module at the doInitialize stage. Then at runOnFunction Stage, this pass will find the insert points and insert calls of this intrinsic function. However, when the -O2 flag is turned on, the strip unused function optimization will automatically delete this

...(rather than by position). Factors have their levels expanded as necessary [...]" The behavior has bitten me fairly hard, because I searched for the origin of the warning in all the wrong places before finding the real one after about 3 hours. (Although I still have not understood _why_ it results in that warning.) I believe the behavior of rbind.data.frame should be fixed, so that it ignores levels attributes when there is no factor class as well. The alternative would be to just add a warning to the documentation that 'unclass' on factors is insufficient if users want...

The documentation for png says: Windows imposes limits on the size of bitmaps: these are not documented in the SDK and may depend on the version of Windows.
