Cool!  Thanks for the "shout out" too.  I remember working on it in late 1999, wondering what the heck we were doing when there was this scary Y2K that we had to worry about.  Little did we know then, how things would turn out.  Y2K was a bust, and Linux took off like crazy.

Now this is a cool use of technology for a good cause.

The flying robots predict where poachers will target wildlife and send in rangers to stop them before they can pull the trigger.

The small-print on these is so great :-)

Always nice when people recognize our efforts.
 
Reviewing presentations from a recent conference that I could not attend, on one slide was this ...

   Backward compatibility
    + The systemd developers don't seem to believe in it.
    + SUSE does, however

Yeah, I noticed that on SUSE systems "stuff still works" more than in certain other environments. Nice work, guys. Much appreciated. (Not the first time I have thanked them publicly for this kind of stuff.)

I just spent the last week or so (off and on) trying to build a working Linux kernel for my Raspberry Pi B board. It would compile just fine, but not work at all. Until yesterday, it never occurred to me that the necessary support was not in the official kernel tree.  I know the various ARM developers had  a history of not getting their changes merged into the official tree, but I thought they had been making good progress and were long past that. How long has the Broadcom bcm2708 been out? #Linux #RaspberryPi

Sounds like a related Linux-based effort, also commonly ARM targeted. That is: being lax about up-streaming your updates.

It's rather old, but I just saw this Sheldon comic. What can I say? It's so true.

Over the weekend our local, not a national chain, pet store was having their annual customer appreciation sale. Picked up a bunch of food, etc. and a nice T shirt. Dog owners will definitely be able to relate. :)

Argh. A spammer that doesn't realize they are a spammer. I got the following from a spam report I filed:
Hello SpamCop user,
 
The email marked as spam below is a part of our Technology prospect email nurture series which includes 6 emails over 30 days. The primary call to action in the emails is to ‘start a free trial’. We purchase technology lists from list providers and funnel them into the nurture on a monthly basis. Our internal Marketing Operations team has processes in place to deter spamming our database and are actively monitoring and scrubbing the database for inactive email addresses. There are also rules in place to avoid sending too many emails to active recipients.

Sigh.

Looks like Linux 4.1 is going to have a brand new low-level interface to kernel performance information. Including the ability for interactive data collection and analysis.  Nice.  :)
 
eBPF is scary powerful, hopefully more people learn about it through example scripts like these.
I've taken one small step with eBPF, but it heralds one giant leap for Linux tracing. # ./bitehist Tracing block device I/O... Interval 5 secs. Ctrl-C to end. kbytes : count distribution 0 -> 1 : 3 | | 2 -> 3 : 0 | | 4 -> 7 : 3395 |************************************* | 8 -> 15 : 1 | | 16 -> 31 ...

At SHARE, we typically have two keynote sessions per conference. The one on Tuesday has been security related for a while now. The video of the one by Phil Young, from SHARE 124 in Seattle has been posted to YouTube now. Titled "How to Embrace Hacker Culture For z/OS" I thought it was very good and hopefully something of a wakeup call for mainframe systems programmers that think no one is interested in trying to crack their systems.

IBM is once again demonstrating that it can be its own worst enemy. This time it involves their new mainframe system, the z13. IBM has a lot of things to be proud about with the z13, but their marketing messaging is definitely not one of them.

I don't understand. Why are you talking about a coupling facility in connection to Linux?
