No Shortage In Tech Workers, Advocacy Groups Say

jacobsm Re:Two sides to every issue (401 comments)

Total BS. I'd take a American IT worker with an inflated ego over a corporate bean counter any day. I've been in the IT field since 1979, and trust me, I'm an expert in my speciality. They might be able to replace me with someone and pay then 1/2 of what I make, but they're not going to get my skillset.

Knowing what to do when things are going along swimmingly is easy. When the shit hits the fan, getting the corporate mainframe back running in minutes rather than hours, or G-d forbid days is worth every penny they pay me. I know it, the people who've been working with me for *mumble* years know it.

A bean counter, I doubt it.

Ask Slashdot: System Administrator Vs Change Advisory Board

jacobsm zOS Maintenance and CAB (294 comments)

I'm the zOS Systems Programmer at a Fortune 500 company. When we do system maintenance cycles our CRB just wants to know when the system environment is changing, not what's changing.

If anyone ever does want to know I do have detailed logs and a before and after image of the maintenance management database (SMP/E Consolidated Software Inventory) for them to peruse. They never do; since they don't understand zOS Systems Programming, and they shouldn't have to. It's their job to manage system availability and to ensure that proper testing and system validation activities were performed. It's my job to manage the environmental change.

For anyone who's foolish enough to ask for detailed documentation of every module, macro, load module, dataset, file in the Unix System Services file system that's being modified, well enjoy yourself.

What I won't stand for, is for someone to have veto power over what maintenance goes on. That's my decision, and since I'm the best person in the organization to decide, I do so.

Fifty Years Ago IBM 'Bet the Company' On the 360 Series Mainframe

jacobsm Re:software (169 comments)

You're 100% correct, but I'll add that it's very difficult to get management to bring in new people and give them the opportunity to learn from people who've had decades of experience in the technology and systems that the business depends on.

In my case I'm coming up on 36 years experience in the mainframe world, and I've got no one to teach my skillset to. As for people not wanting to work in a mainframe environment I've got a few comments that might help change their minds.

1) The mainframe isn't going away anytime soon.
2) Competition for jobs in the field is going to be on the side of the job seeker, not the employer once demand picks up (as we geezers retire) and supply of talent will be lower than for the more sexy IT positions.
3) According to the the free market system, if demand is high and supply low, prices rise. And in this case that means your salary.

Target Ignored Signs of Data Breach

jacobsm Re:To be fair? (95 comments)

Not only InfoSec, most warnings from the people who know up to the people who don't know, but have authority to act, or spend money are just ignored.

Several years ago I told Data Center management that a vital piece of hardware had reached end of life and needed to be replaced else we'd be at risk for a total system outage that might last for days.

They didn't want to spend the $30,000 dollars until they absolutely had to, so they ignored my recommendation. In the end, nothing bad happened, but it very easily could have and we'd have lost revenue in the millions of dollars, just so as not to spend money before they absolutely had to.

Complete Microsoft EMET Bypass Developed

jacobsm Re:Architecturally Insecure (116 comments)

I disagree. It's the direct descendant of S/360 and has about 50 years of steady product improvements built in. Malware, running with general user access rights cannot affect system processes in any way, and cannot alter(or read) any memory location that it doesn't have access to. The zSeries hardware, with the operating system is a powerful combination, that Windows and commodity hardware can't touch.

I'm a zOS Operating Systems Programmer with 35+ years experience, and while there have been published security and system integrity patches issued on occasion, Windows has it beat by a mile.

Complete Microsoft EMET Bypass Developed

jacobsm Architecturally Insecure (116 comments)

Windows, any version, is architecturally insecure. While it can be patched, you're never going to be able to completely eliminate the insecurities. Does Microsoft have a system integrity statement like this? I highly doubt it.

IBM’s commitment includes design and development practices intended to prevent unauthorized application programs, subsystems, and users from bypassing z/OS security – that is, to prevent them from gaining access, circumventing, disabling, altering, or obtaining control of key z/OS system processes and resources unless allowed by the installation. Specifically, z/OS “System Integrity” is defined as the inability of any program not authorized by a mechanism under the installation’s control to circumvent or disable store or fetch protection, access a resource protected by the z/OS Security Server (RACF®), or obtain control in an authorized state; that is, in supervisor state, with a protection key less than eight (8), or Authorized Program Facility (APF) authorized. In the event that an IBM System Integrity problem is reported, IBM will always take action to resolve it

Does Relying On an IDE Make You a Bad Programmer?

What Will Ubiquitous 3D Printing Do To IP Laws?

jacobsm Changes in technology always affects society. (347 comments)

Laws have to change as technology makes them obsolete. That's not to say that people who have an interest in living in the past won't kick, scream and bribe their congress critters, but eventually they'll lose.

From Heinlein's Life-Line;

There has grown up in the minds of certain groups in this country the notion that because a man or corporation has made a profit out of the public for a number of years, the government and the courts are charged with the duty of guaranteeing such profit in the future, even in the face of changing circumstances and contrary to public interest. This strange doctrine is not supported by statute or common law. Neither individuals nor corporations have any right to come into court and ask that the clock of history be stopped, or turned back.

NSA Foils Much Internet Encryption

jacobsm Deniability has been improved (607 comments)

Now that we know the NSA can intercept and decrypt any message, doesn't it also mean that they can change the message to whatever they want, re-encrypt it, and pull it out in a court of law as evidence?

If they do, or even if they don't, I can now say they did, and they can't prove they didn't.

Virtualization - Live Guest Relocation

jacobsm jacobsm writes  |  more than 5 years ago

jacobsm (661831) writes "Included in this past Tuesday's z/VM 6.1 preview announcement is a statement of direction for a "live guest relocation feature". IBM intends to further strengthen single system image support by providing live guest relocation. This is planned to provide the capability to move a running Linux virtual machine from one single system image member system to another. This is intended to further enhance workload management across a set of z/VM systems and to help clients avoid planned outages for virtual servers."

45th anniversary of the mainframe

jacobsm jacobsm writes  |  more than 5 years ago

jacobsm writes "Today, April 7th is the 45 anniversary of the announcement of the IBM System 360. This computer is the foundation of all current mainframe computer systems. Some other historic events in 1964 were, Ford motor company introduced the Ford Mustang on April 17 and Stanley Kubrick had lunch with Arthur C. Clarke at Tavern on the Green in NYC to discuss the possibility of making the "definitive science fiction movie".....the result was "2001: A Space Odyssey".

The Green Data Center: Steps for the Journey

jacobsm jacobsm writes  |  more than 6 years ago

jacobsm (661831) writes "It is part Sales talk but has a lot of interesting information also. The information technology (IT) industry is a big user of resources as well as an enabler of efficiencies that reduce CO2 emissions. However, as companies continue to grow to meet the demands of their customers and as environmental concerns continue to be an issue, organizations are looking for ways to reduce corporate energy consumption and to become more environmentally responsible; to become green. This IBM Redpaper can help your IT organization as it begins the journey to becoming a green data center. IBM wants to help others, particularly our clients, to chart a course to reap the benefits of lower costs and improved sustainability that running a green data center can provide. Understanding what is possible can speed your journey to an optimized green data center with sustainability designed into both the IT and facilities infrastructures. Although this paper is not all inclusive, it provides a quick start for going green in data centers. It also provides additional pointers and information. You can use this paper as a guide to becoming more energy efficient. A link to the IBM Redpaper can be found here: Download PDF (2.7 MB)"
