How I accidentally found a way to mess with “Peggy”

Dave Farquhar scams, security , , , ,

“Peggy” from “Computer Support Department” just won’t give up. He called me again at about 8 PM this evening. This time, I played along. I had a thrift-store junker PC for him to infect with his malware. The only problem was, the hard drive wasn’t connected and neither was the power cord. So I quickly hooked all that up, booted up, and then played along.

“I want you to click on Internet Explorer.”

“OK.”

“What do you see?”

“Page cannot be found.”

Thus I learned that Peggy isn’t very good at troubleshooting network issues. Read more

An upgrade. And an upsell.

Dave Farquhar Uncategorized , , , , , , , ,

I bought a new radio for my venerable 2002 Honda Civic this weekend. I want to be able to listen to security podcasts on my commute, which wasn’t practical with my factory radio. So, off to the nearest car audio shop (Custom Sounds) I went, skipping both Best Buy and Audio Express. I looked at a couple of $119 decks, then the salesman mentioned an Alpine HD radio deck for $129, and a Sony deck with Bluetooth for $149. Bluetooth didn’t really interest me much, but HD radio seemed worth the extra $10. To me, the secondary HD stations seem more interesting than the primary ones. Then again, I’m the guy who skips right past the hits on U2’s The Joshua Tree and cues up “Red Hill Mining Town.” The stuff I really like generally doesn’t do all that well on mainstream radio.

But my main motivation was to get a radio with a USB port, so I can snarf down a few hours’ worth of podcasts every week to a USB thumb drive, plug it in, and stay in touch with the security world. Total overkill for an Alpine, but like the salesman said, Alpines aren’t crazy expensive anymore like I remember them being in the early 1990s. Read more

Blame IT.

Earlier this month, Cringely blamed Best Buy’s IT for the company’s woes. His observations make sense. I can only add two things.

“It’s your happy place.”

Dave Farquhar model railroading, Toy trains , , , , , ,

Someone told me today that she didn’t quite get the appeal of model railroading, that it must be a male thing. And that’s fair: Model railroads were first invented by a dollhouse maker so they would have something to market to boys. That company still markets trains, but no longer markets dollhouses, so I guess you could say it was successful.

Here’s how I summed up the appeal.

Antivirus progress

Dave Farquhar security , , , ,

When Microsoft Security Essentials first came out, it was an improvement in antivirus performance. Now, it’s middle of the pack, according to PC Magazine. That’s great. Vendors are finally taking performance seriously.

What that means is that by replacing MSE with F-Secure Anti-Virus 2013, Kaspersky Anti-Virus (2013), Sophos Anti-Virus 10.2, ESET NOD32 Antivirus 6, Norton Antivirus (2013), Avast Free Antivirus 8, or Bitdefender Antivirus Plus 2013, you can speed up your computer. Considering Norton Antivirus was once bottom-of-the-barrel in the performance arena, I see this as a good thing.

Of the bunch, Avast is the only freebie. Though if your ISP offers one of the others as part of your subscription, or you don’t mind paying for antivirus, the others are an option. But maybe, just maybe, if I replace Microsoft Security Essentials with Avast, Peggy will quit calling me at dinnertime and telling me my computer is slow. But I doubt it. Read more

Windows vs. Linux kernel performance

An anonymous Microsoft developer spilled some juicy opinions about why Windows kernel performance isn’t all it could be and answered some longstanding questions about Windows vs. Linux kernel performance in the process. Although he has recanted much of what he said, some of his insights make a ton of sense.

Notes on the Compaq Presario SR2011WM

Dave Farquhar Hardware , , , , , , ,

I’ve been working on a Compaq Presario SR2011WM. It’s a basic, low-end, single-core Celeron D system from 2006 or so. It can take up to 2 GB of RAM, runs Windows XP adequately, and has SATA ports, so you can put an SSD in it if you want. But don’t be fooled by the name–the Celeron in this machine is single core, and has a Prescott-era Pentium 4 core in it at that, not a low-TDP, Pentium D-style core.

In case you’re wondering, the easiest way to get it to boot from USB is to plug in a USB drive, hit ESC as the system runs POST, then select your USB drive from the menu.

Now let’s talk about options for upgrades. Read more

Two simple ways to increase your credit score

Two simple ways to increase your credit score

I have a friend who makes more money than me, has no debt except for a small mortgage, and his credit score is 150 points lower than mine. By becoming more like me, you can increase your credit score.

The key difference between us is that he puts a couple thousand into a checking account at the first of every month and pays for everything with a debit card. I do the same thing, but use a credit card, and pay the credit card off at the end of the month.

The NSA’s guide to finding things on the Internet is available now

Dave Farquhar security ,

A wonderful NSA document called Untangling the Web, thanks to a FOIA request, is now available and free for all to download and use. Although dated, the book will prove highly useful. If you company or client is exposing data that it shouldn’t to the public Internet, this book will help you find it, so you can correct it.

The copy isn’t perfect. It’s a bit dated, and it’s a straight scan to PDF, so it isn’t searchable, and it’s not the clearest, cleanest copy. I’m cleaning up a copy for my own use right now. I expect to use it, and often. It isn’t a document I’ve been privileged to see before, so I’m excited to have a chance now to study it and learn its techniques. Read more
