Why I set work aside for a while before calling it done

Dave Farquhar Writing , , ,

A former supervisor called me the other day. He’s having quality control issues at his new gig, and quality control was one of the things I did when I was working for him. He wanted my insight. And he was very direct with one question he asked me.

“You would always set work aside and then come back to it,” he said. “Why?”

He knew my tactic worked, but wanted to know why it worked. Read more

How to increase the capacity of a Log Logic appliance by 45%

Dave Farquhar security, Software , ,

My 9-5 gig revolves primarily around Tibco LogLogic (I’ll write it as Log Logic going forward, as I write in English, not C++), which is a centralized logging product. The appliances collect logs from a variety of dissimilar systems and present you with a unified, web-based interface to search them. When something goes wrong, having all of the logs in one place is invaluable for figuring it out.

That value comes at a price. I don’t know exactly what these appliances cost, but generally speaking, $100,000 is a good starting point for an estimate. So what if I told you that you could store 45% more data on these expensive appliances, and increase their performance very modestly (2-5 percent) in the process? Read on.

Hacker chasing, circa 1987

I’m catching up on reading. Next on my reading list is The Cuckoo’s Egg, (Amazon link), Clifford Stoll’s memoir of chasing down a computer hacker in the late 1980s. In it, he describes a very different world, ruled by mainframes and minicomputers, where Unix was something special, IBM still made PCs, but desktop PCs and Macintoshes only received occasional mention, and academia and the military owned the Internet, almost literally. And, oh, by the way, the Cold War was still raging.

The remarkable thing about this book is that it’s an approachable spy thriller, written in 1989, that explains computer security to an audience that had never seen or heard of the Internet. You don’t have to be a security professional to appreciate it, though it’s a classic in the computer security world–many people read it in the late 1980s and early 1990s and decided to get into the field.

How to get started in regulatory compliance

Dave Farquhar security , , , , , , ,

I had a search query about getting started in regulatory compliance, which I’ve written about before, but more from an organizational perspective. That won’t help you much from a career perspective.

I think most any CISSP will answer that question similarly, so I’ll take a stab at it. Read more

How to edit a hosts file in Android

Someone asked me how to edit a hosts file in Android, which was a trick I used to recommend in Windows. Editing a hosts file is really two questions: Do you really want to edit it, or do you want to replace it?

Another perspective on Y2K

Dave Farquhar Retro Computing , , , , , , , , ,

Rob O’Hara stumbled across a stash of Y2K survivalist magazines and wrote about it. I wasn’t going to be surprised if there were some minor glitches, but I wasn’t expecting the apocalypse. I withdrew a couple hundred bucks from the bank a few days in advance and filled my bathtub with water the night before, so I would have a supply of money and water to tide me over if some glitch interrupted either of them for a day or two.

In late 1999, a lot of people said I was being reckless. Today, people think I was being excessively paranoid. It’s funny how perspectives change. Read more

Cringely takes on Ashton Kutcher’s movie about Steve Jobs

Dave Farquhar Macintosh, Retro Computing , , , , , , , ,

Mark Stephens, a.k.a. Robert X. Cringely, wrote last week about his disappointment in Ashton Kutcher’s movie Jobs, about the late Apple co-founder and CEO.

Here’s the most important part of his quasi-review:

[S]omething happened during Steve’s NeXT years (which occupy less than a 60 seconds of this 122 minute film) that turned Jobs from a brat into a leader, but they don’t bother to cover that. In his later years Steve still wasn’t an easy guy to know but he was an easier guy to know. His gut for product was still good but his positions were more considered and thought out. He inspired workers without trying so much to dominate or hypnotize them.

Indeed. Read more

DoSing your cubicle neighbor

Dave Farquhar security, War Stories

My baby at work is a centralized logging tool. That means my system has to touch every other system in this large company’s large network, which is kind of cool. Not many projects deal with that many different things, and I’m seeing some things I haven’t seen since college–and never expected to see in the real world, actually.

A week or two ago, we had some trouble pulling the logs in from a highly specialized system. That happens. Unix is easy, Windows is almost as easy–yes, the world of logging is a little bit upside down–but the one-off systems that don’t fit into neat categories take a lot longer to bring into the fold.

The problem was that the user account my tool uses kept getting locked out. Read more

How many Fortune 25 companies does it take to change a light bulb?

Dave Farquhar Humor/Satire, War Stories , , , , , ,

I’m working right now for a Fortune 25 company. This story is going to sound like bragging, so I’ll ask forgiveness in advance. Maybe if I mention I’m a contractor, then it’s not bragging quite so bad. Read more

Where Microsoft lost its way

John C. Dvorak wrote an analysis of how Microsoft lost its way with Windows 8 this week.

All in all it sounds reasonable to me. His recollection of DOS and some DOS version 8 confused me at first, but that was what the DOS buried in Windows ME was called. But mentioning it is appropriate, because it shows how DOS faded from center stage to being barely visible in the end, to the point where it was difficult to dig it out, and that it took 15 years for it to happen. He’s completely right, that if Microsoft had pulled the plug on DOS in 1985, Windows would have failed. Read more
