I don't understand why IBM is so insistent that the two new LinuxONE mainframes are "the first Linux-only" machines. The first z890 model was a Linux-only system, and customers have been able to order IFL-only machines for quite a while.

My other problem with this set of announcements is the insistence on referring to "8,000 virtual machines" without mentioning that this is possible with only one of the hypervisors they list: z/VM.

Then, they show a list of open source packages that are "now available" for mainframe Linux that have been available for quite some time: Postgresql, MariaDB.

Finally, I hope they do a better job of figuring out the "metered" licensing costs. I would really hate to see Linux users jumping through the same sort of hoops and contorting themselves the way I see a lot of z/OS shops do to keep software costs under control.

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.

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?

And the good news just keeps coming. SUSE Manager 2.1 can now both manage clients on, and run the server on the mainframe.

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. :)

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.

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.)
