Cross Compiling Clarity

I have an important distinction to make clear... Cross Compiling is using a machine with a different processor type than the target machine for your program. So, you have a PC with an Intel Core 2 Duo in it, and you use a compiler to output an ARM executable, that is cross compiling. If you're on an Intel Core Duo toting 15" MacBook pro (from 2006 ) and you use that to produce the same ARM executable, that's still cross-compiling.  BUT if you use that MacBook to generate a windows executable it's not cross compiling, as the processor is the same in both targets, you're not crossing over... Some folks argue this differently, because you're crossing between the Windows and Apple OS's you're cross-compiling.  In my book, and by the definition given elsewhere, you're not, in this case you are cross-platform (the platform being the OS) but you're not cross compiling because the processors are the same family. That's all, I just wanted this out t...

C++: The Dilemma of using Exceptions

Image
As a C++ developer I've recently been in the midst of the Exceptions debate.  Exceptions as a feature of the C++ language have long divided the community, naively I've often put this down to their coming to the language from elsewhere (C perhaps) where exceptions were not the norm. This was a mistake, for in the projects I've previously worked upon the overhead of an exception compared to the ramifications of the error resulting in a crash have often totally outweighed the overhead, making deciding to employ an exception exceptionally easy (*bum bum*).  Exceptions were the norm, still are and should be to you too (according to the C++ Core Guidelines https://github.com/isocpp/CppCoreGuidelines/blob/master/CppCoreGuidelines.md#Ri-except ). The difficulty, the dilemma if you will, comes not from the feature, but the cost.  If you application domain demands high performance you can not risk using exceptions, the argument carries on therefore whether in not using them to avoi...

Server Admin : How Good is your Backup?

Image
How robust is your back up solution?  Go on, be honest with yourself, how good is it?... Because I've seen a whole host of them and, at this very moment, this is the screen up on one of my servers.... Yes, my raid 5, just a test raid 5 with three really bad recycled SAS drives in it has failed; this doesn't surprise me, but it does delay me because I now have to rebuild the data... However, I know my data is good.... Lets see how good my back up is. This back up is coming from a DD created raw image of the virtual disk, stored to and soon lifted from my NFS accessible ZFS mirrored back up server. Therefore you would be right to ask, why are you rebuilding the virtual RAID disk in the above screen shot?  Well, I'm going to test my back up strategy! I popped the known bad disk and the good disks out, replaced all three and I'm able to test a restore to a new virtual disk set, I have a USB boot drive ready, this is a test. This kind of test, a real live restore, is sorely ...
