Not only that; but also, by virtue of the "promo pool" being the "losers" in this theory, it subclasses them without saying so (into at least three types - losers that will avoid promotion at almost all cost, losers that

I love reading the "things I won't work with" series ... a shame it's no longer being added to. Just curious: why did Derek Lowe stop writing these ?

A lot of these "organisational models" treat organisational behaviour as a kind of game; you can get ahead by exploiting game masters' mistakes, by cheating, or possibly by knowing and playing the rules really well. And just

DTrace and eBPF are "not so different" in the sense that dtrace programs / hooks are also a form of low-level code / instruction set that the kernel (dtrace driver) validates at load. It's an "internal" ar

you're right ... "rusty" memory there. You made me check the sources ... it uses libproc but not libdtrace. (can I be forgiven since I haven't really touched anything Solaris-ish for near 15 years ?)

You have rather high expectations towards the supervisor there ... maybe you were one of the "unlucky" ones who had a genius supervisor ... There aren't that many people in the world who write bootloader code daily for a livi

You can only grow the stack automatically if you "prereserve" the virtual address space for it. Then it becomes just a question of "committing" the memory at time of need. Default options to mmap() should actually give y

yes, truss has been based on / implemented in terms of dtrace since Solaris 10. (dtrace userland is a library; you can, if you so choose, write your own tooling there. The command is "just a wrapper", a lot of similarities to

Man this brings back so many memories :-) Definitely a fun read. Debugging crashes has, in the last decade or so, become something a bit like a "lost art". Noone looks at coredumps in the cloud ... I don't want to outdo you o

There is value way beyond the immediate service given in a human to human interaction; we're social animals after all and tend to derive a form of pleasure out of "being with others". In the same sense that granny went prayin

You "anything it wants" folks really annoy me a little. If the compiler can, compile-time, detect that code is prone to memory corruption, it can warn the developer. If it can't detect it at compile time, will and shall it ad

"real" (large) C/C++ programs get much of their complexity from the fact that it's hundred of "sources" (both compiled and libraries) that sometimes, or even often, share global state and at best use a form of

I was (more) of a Solaris/x86 kernel guy on that particular level and know the x86 kernel did not use task gates for doors (or any context switching other than the double fault handler). Linux did taskswitch via task gates on x86 till

Think of it in terms of REST. A door is an endpoint/path provided by a service. The client can make a request to it (call it). The server can/will respond. The "endpoint" is set up via door_create(); the client connects

The risk of injury as such has little to do with how strongly lit the path is; people break their legs at daytime hikes alright. Does it help recovery/discovery ? Maybe, but again that more depends how busy the road is; your "lone

PIPS made it very clear that the way-forward was a unixish kernel/base system - as Apple did, as Android did, and in fact, years before either, as Nokia did with Maemo/Meego. It was pure facade to say "continue with Symbian b

Amazing to see a curator attempt to give us an impression how lighting "felt" in antiquity. Today, we too often see light as mere utilitarian anathema to "darkness" - which breeds evil, is to be banned to the shadows, or
