AIX and mysql binaries PDF Print E-mail
Written by Michael Felt   

Before MYSQL had been purchased by Sun binaries for AIX were easy to find. These days you need to go to https://downloads.skysql.com/archives to find my MYSQL and SUN provided. Oracle basically stopped supporting any hardware category they were not selling.

Still, good to know someone copied everything that was out there under the "copy-able" license.

Now you know where to go!

 
Open Source Software happiness PDF Print E-mail
Written by Michael Felt   

Time for some happy frustration Wink as I start getting back to packaging software for AIX. I would probably have a lot less trouble if I took AIX 6.1 as the base level - but I am trying to compile everything using the IBM xlC compiler (v11) and AIX 5.3 TL7 (CSP).

My first serious project,  several years back, was ASF (Apache Software Foundation) HTTPD. ASF has always been very open and willing to listen and make changes when applicable - and give constructive hints when that was more applicable. And, for the record, I managed to get both HTTPD 2.2.28 and 2.4.9 repackaged without too much of a problem last week - check out httpd://dl.aixtools.net/httpd for files - if interested.

POWER8 Announcements - What's New? PDF Print E-mail
Written by Michael Felt   

The coming days (as I unfortunately missed the pre-release news) more and more will be revealed about what is new in POWER8. I am very curious of course.

One item that caught my attention - immediately - is the focus that was takenon improving the SMT thread (or logical CPU) performance of the processor cores compared to performance metrics that are based on all threads collectively - for maximum gain.

Why is this important? Because even today many applications are still single-threaded. Or, unfortunately most applications, even modern ones, do not utilize the benefits of super scalar multi-threading (POWER multi-threading is known as SMT - Simultaneous Multi-Threading whereas Intel is best known for HyperThreading).

Security is layered like an Onion PDF Print E-mail
Written by Michael Felt   

An Operating System cannot secure everything

I do not know much about Axiomatics but their ad caught my eye. And got me thinking it was time to write a quick blog entry.

Axiomatics have a product that implements what they call ABAC - Attribute Based Access Control. They state that this goes beyond RBAC - Role Based Access Control. And I agree - from an architectural (i.e., the layers of an onion) viewpoint - that they are correct.

I hope this triggers a thought process in you as it did in me and remember that as you think about how to keep your system secure you need to remember security is implemented layer by layer.

Over the years new technologies appear - and define new layers. Over 30 years ago simple file protection bits was enough, then technologies like sudo became the next layer, and now at the OS level we have RBAC technologies and at application level a new (open) standard - XAMCL .
