Builds in Go 1.5 will be slower by a factor of about two. The automatic translation of the compiler and linker from C to Go resulted in unidiomatic Go code that performs poorly compared to well-written Go. Analysis tools and refactoring helped to improve the code, but much remains to be done. Further profiling and optimization will continue in Go 1.6 and future releases. For more details, see these slides and associated video.

And replacing it with something slower.

Not quite. kmscon uses the same key binding format as X because it re-uses the same code.

I tried using it once, I replaced one of my consoles with kmscon and the only difference I saw was a subtle change in text colours. The fonts and other terminal behaviour seemed identical.

But it only seemed to work for me with the open source driver for nvidia cards. And that has other limitations.

To fix this would require moving the HID key value translations into the kernel keyboard driver, rather than having it (mostly) in user space in all three instances (X, Weyland, console).

Or just remove in-kernel VT consoles completely, and replace them with a user-space implementation.

newgrp is a setuid binary. During the startup of that process, if the vulnerable environment variable is set, dyld will open the requested file. Since stdin=0 / stdout=1 / stderr=2 should be the only open files, the next available file descriptor would be 3. So open() should give dyld that file descriptor.

newgrp will then drop it's privileges and run your shell, perhaps by calling exec() without forking another process. Since the file wasn't specified to close on exec, the shell will inherit the open file descriptor.

If we pass "echo "[something]" >&3" to stdin of newgrp, the echo will be executed in the new shell. Even though that shell is running as the logged in user, fd=3 was opened by root. So the result can be appended to any file you want.

That's a good description, but everyone is still missing the actual cause. Firstly, the European Union is founded on an ideology that doesn't allow for an economic crisis. Second, when the crisis hit in 2008, the Greek *private* sector *reduced* their bank borrowing. Their money supply shrank, velocity shrank too, jobs were lost, tax receipts went down. Their government debt ratio went up, not because they were borrowing more, but because GDP fell. But the Euro doesn't allow Greece to run a large deficit, nor to increase their debt level, so they can't stimulate their economy to prevent further job losses.

The Greek government weren't in good shape before, but the combination of a crisis and the rules imposed by the Union have wiped them out.

If it wasn't for Newton, we wouldn't have to eat bruised apples.
