What salary do I need to buy a house?

Dave Farquhar Saving money July 19, 2017July 3, 2018college education, computer security, estate sales, interest rates, IRS, mortgage, oakville

What salary do I need to buy a house? I struggled with that question in my 20s and it probably kept me renting a year or so longer than I really needed to be. Then again, considering the housing crisis of 2007-2008, renting a year or so longer was a small price to pay to avoid potentially making the biggest financial mistake of my life.

One of the reasons for that financial crisis was not enough people asking that question. A second reason was banks being dishonest about the answer. For the record, I think buying a house is a good idea and it’s worth it. But you have to be sane about it to keep from getting into trouble.

Using Adsense with WordPress

Dave Farquhar Wordpress July 14, 2017January 28, 2018computer security, journalism, SEO

I first started using Google Adsense sometime in 2003 or 2004. But using Adsense with WordPress isn’t completely straightforward. So here’s an easy, concise guide to using Adsense with WordPress, including within your content.

I’m not a full-time blogger. I’m a computer security analyst by day, and blog part time. I went to journalism school in the ’90s in hopes of landing a job that doesn’t exist anymore. Some of what I learned about printing magazines applies to modern blogging. Some of it is subtly different. I don’t need to make a ton of money blogging, but I don’t blog to lose money either. There are an awful lot of bad people with bad motives making a lot of money online off sketchy or downright dishonest content. I’m writing this so the good guys can learn what the bad guys know, and make a little money too.

What happened to Digital Equipment Corporation?

Dave Farquhar Retro Computing June 20, 2017October 3, 20181980s, 1990s, altavista, amiga, apple, commodore, compaq, computer security, d-link, DEC, Digital Equipment Corporation, Digital Research, firewall, hp, IBM, intel, lexmark, linksys, macintosh, netgear, PIP, spam, syntax, unix, windows nt, x86

Digital Equipment Corporation was perhaps the second most important computer company in history, behind IBM. Its minicomputers challenged IBM, and, indeed, Unix first ran on a DEC PDP-7. DEC’s Alpha CPU was one of the few chips to make Intel nervous for its x86 line. It created the first really good Internet search engine. In a just and perfect world, DEC would still be dominating. Instead, it faded away in the 1990s. What happened to Digital Equipment Corporation, or DEC?

There’s a short answer and a long answer.

A Viglink review

I think the Web needs a non-spammy and honest Viglink review. So I’ll relate my experience using Viglink over the course of several years. I recommend it, generally. That said, takes some work, and that explains some of the other Viglink reviews you might see out there.

On Monday, March 13 at approximately 10:30 AM CST, I will be appearing on KFUO Radio’s Faith and Family program to discuss home computer security with host Andy Bates. One of the questions he’s planning to ask: How can I know how secure my home computer is? Or, to put his question another way, how safe is my computer from hackers?

I’m going to use this space to elaborate ahead of time on some of the things we are going to talk about. We could talk for an hour on any of the questions he’s going to ask, and he gave me three questions and 25 minutes. This is my workaround.

This, fortunately, may be the easiest question to answer and the easiest step to implement.

How easily can someone hack my home computer and steal personal information?

On Monday, March 13 at approximately 10:30 AM CST, I will be appearing on KFUO Radio’s Faith and Family program to discuss home computer security with host Andy Bates. Here’s the scariest question he’s planning to ask: How easily can someone hack my home computer and steal personal information?

Someone asked me that question at work once, except it was about a work computer. I whipped out a copy of a book about Metasploit, flipped to page 137, and started reading. My point was that I could teach this guy how. He didn’t take it well, so I don’t recommend doing that.

My point that I could teach this guy how to do it still stands, though. And I think I could teach Andy how too.

Pros and cons of RightTrack or SnapShot devices

Insurance companies are starting to offer discounts if you plug one of their devices, often called a RightTrack or SnapShot, into your car’s ODB2 port.

One of my college buddies asked me about them when his insurance company offered his family a 5% discount to plug these into their cars, and then make them eligible for up to another 25%. Those are compelling numbers. So what are the potential drawbacks?

Using Splunk to find bad guys in your network

Dave Farquhar security November 16, 2015April 23, 2017computer security, Log Logic, malware, splunk

I’ve covered event logging before, but the excellent site Malware Archaelogy has some cheat sheets that include Splunk queries you can use to find incidents or malware operating in your network, or even use to create dashboards so you can keep an eye on things. Malware Archaelogy’s list of events to log is a bit different from what I covered before, but there’s a considerable amount of overlap. You probably want what they recommend and what anyone else is recommending.

The key to corporate computer security is situational awareness, and I don’t think anyone sells a blinky box that provides enough of that. But you can build it with Splunk.

And, for what it’s worth, I do recommend Splunk. I’ve used Log Logic in the past, and its searches often take days to finish, which means Log Logic is so slow that by the time you find anything in it, it’s likely to be too late. Splunk isn’t quite real-time, but you can find stuff in a few minutes.
