No, You Don’t Have a Fax. An Analysis of a Spam Email

Examples of clues to look for.

A fake fax notice landed in my inbox and turned out to be a perfect teaching tool. I'll walk you through the clues that gave it away, from the sender's address to the hidden headers, and show you how AI is about to make spotting spam much harder.

We all get spam.

That might be the most obvious statement I’ve ever made here. Smile Unfortunately, it’s true, and seemingly truer every day.

I decided to use a piece of spam I got to show you how to identify spam.

How to Select Text Faster: Six Tricks You May Not Know

Some convenient text-selection techniques you might be missing.

Dragging a mouse across text works, but it's slow and awkward. I'll show you how to double-click, triple-click, or click in the margin to select words, paragraphs, and lines. Learn several easy selection tricks plus one small catch that can break a password.

This might fall into the category of “everyone knows that”, when, in fact, everyone does not know it. As a result, they’re missing out on some convenient and powerful techniques.

This is about several ways of selecting text.

I’ll also explain what selecting means.

First, do no harm.

Registry cleaners can be dangerous. I'll review when they might be appropriate, which I'd use, and how to use them safely.

Question: What is the best software to buy to fix and clean the Windows registry?

There is a wide variety of opinions on registry cleaners and PC cleaning tools. Many people believe they’re valuable, important tools to keep your system running smoothly.

I strongly disagree. Most of the time, they’re so much snake oil.

What External Drive Should I Get?

There are many choices, and they keep changing.

I'll review what matters when buying an external backup drive, plus a few current picks worth considering. Capacity, USB speed, SSD versus traditional hard disk, and portable versus desktop can all be confusing.

I frequently recommend you purchase an external hard drive for your backups. Backing up regularly to an external drive is probably the single most important step in an overall backup strategy.

The inevitable question is, “What external drive should I buy?”

The problem, of course, is that the answer keeps changing. Technology evolves, and as a result, so does my recommendation.

Let me give you a few guidelines, and then a few current (as of this writing) picks.

Should I Repair or Replace My Computer?

You can do either, but which is best?

Is it time to fix or replace your computer? The right choice depends on your budget, the machine's age, your warranty, and how much time you're willing to spend. I'll review the key factors and tell the story of my own laptop replacement.

Every so often, it’s time to replace one trusty but tired workhorse with a newer model. But leading up to that, there might be opportunities to repair or upgrade instead.

As you can imagine, there’s no single answer to this question. It depends on everything from your budget to the age of your computer to how you use it and your future plans.

Since I have no way of giving you a clear “repair or replace” answer for your specific situation, I’ll review what you should consider as you decide. I’ll also review the process that led me to replace one of my computers some years ago.

Checking and Repairing a Disk with CHKDSK

Your computer has a built-in tool for catching hard drive problems before they turn into bigger headaches. I'll walk you through running CHKDSK from Windows Explorer and the command line, explain what it checks, and show you where to find results after a scheduled scan.

CHKDSK has been around longer than Windows. This utility has changed dramatically for new environments and new disk formats, but in some ways, it’s pretty much the same old disk-checking utility we’ve used since the days of MS-DOS.

Regardless of its age or origins, CHKDSK is an important tool for disk maintenance and, in some cases, recovery from a variety of disk-related issues.

Let’s run CHKDSK.

Does All This Talk of AI Mean I Should Choose a Different Career?

Only if you’re looking for an excuse.

Worried that AI is making coding skills useless? Understanding how to code still gives you an edge, even in the age of AI tools and vibe coding. Find out why your passion and interests, not trends, should guide your tech career choices.

Question: For years, it’s been drummed into me that I should learn coding. Coding was the future, and it would lead to a great job. Now I hear that coding’s not the thing anymore, and I should focus on AI. How long will that last before it changes yet again? Should I just give up on a tech job?

No, you should not. Not if it’s your passion, anyway.

Here’s the thing. We’ve been in similar situations before. Don’t believe me? The title of this article is only one word different from another article I wrote: Does All This Talk of Outsourcing Mean I Should Choose a Different Career?

I wrote that article just over twenty years ago.

Everything old is new again.

Responses to Your Three Common Password Manager Objections

Security experts agree: you should use one.

Many people avoid password managers because they seem hard to set up, difficult to trust, or easy to lock yourself out of. I'll look at each objection and show you why they're not as concerning as they seem. Security experts say a password manager is the smartest step you can take.

A recent episode of the Random But Memorable podcast, “Another Masked Vigilante Fear with Karen Renaud”, discussed what keeps people from using password managers. The podcast’s guest had published an article in The Wall Street Journal called “What Keeps People From Using Password Managers?”

The article came down to three specific reasons.

I want to address them.

The 50-year Takeaway

Looking forward by looking back.

I'll look back at the pace of change in my 50 years in tech and ask the question, "What should today's kids learn for a future none of us can predict?" The answer isn't a skill at all. It's a way of thinking that remains critical no matter what you choose to do.

I’m Drowning in Spam. What Can I Do?

You can’t stop spam, but you can manage it.

Three hundred spam emails a day? You're not alone, and no, blocking senders won't fix it. I'll discuss why blocking is pointless, why a full spam folder means things are working, and how to trains your email program to keep more junk out of your inbox.
A Corgi sitting in front of a desktop computer from which a tidal wave of spam email is cascading over him.
(Image: Gemini)
Question: I receive about 300 emails daily. I have no one to help me and I would like to be able to block all this crap. I am not very smart about PCs and need simple instructions I can follow. If I continue to receive certain pornographic or offensive emails, how do I ban them? If I open it up to get their email address to try to block them, what happens then? I need all the help I can get because this is too much to take care of daily. I do delete my history daily, but I don’t think that helps in blocking them. I use Yahoo as my mail provider.

Assuming you mean you get 300 spam emails a day, I agree that’s a fair amount. Between my various email accounts, I suspect I probably get about the same.

The question is not how to stop spam. Ultimately, there’s no way for you and me to do that.

The question is how to deal with it when you get it so it’s a minor annoyance rather than an overwhelming chore, and how to avoid it — or at least minimize it — in the first place.

What Happened When My “Bank” Called Me

I practiced what I preach.

Your bank calls about a suspicious charge. The caller ID matches, they know your account details, and everything sounds legit. But is it really your bank, or is it a scammer? It happened to me. I'll share the steps I took to protect myself.

The other day, I got a call from my bank. They wanted to talk to me about a suspicious transaction.

They said it was my bank, but was it? It certainly started with the hallmark of a scam.

So, here’s what I did.

5 Steps to Better Wi-Fi In Your House

How to improve your wireless connection. (Hint: it’s not your ISP.)

I'll walk you through easy ways to place your router, cut interference, pick better channels, and boost your signal so every device connects faster.

Question: My WiFi supports 802.11 a/b/g/n. I want to know which is actually being used, and if it is not optimal, what can I do to improve it? Or is my slow Wi-Fi something I blame on my ISP?

The a/b/g/n are all different variations of the 802.11 Wi-Fi protocol. Which one gets used is mostly out of your control. On the other hand, there are definitely steps that can improve your Wi-Fi performance at home.

And we’ll also touch on one of my pet peeves: ISPs marketing themselves as having “the fastest Wi-Fi”, which has nothing to do with the service we pay them for every month.

Nope. Let’s not make that assumption.

Let me show you four different ways to reformat a disk.

How Passkeys Work (A No-Tech Version)

Simple in concept.

Passwords are on their way out. I'll discuss what passkeys actually are, how they work, what happens if you lose your device, and how they protect you from phishing, malware, and data breaches... without the technical jargon.

Question: I read your article What Is a Passkey?, and I watched your video, Say Goodbye to Passwords: Passkeys Explained Simply,  and I’m sorry, but if that’s “simple”, I’m never going to understand passkeys, much less use them.

I get it. In those articles, I went into some implementation details that, in all honesty, most people probably don’t care to know about. They ended up distracting from the important stuff.

Fair enough. Let’s see if I can simplify things further and use this opportunity to address some common questions and concerns.

How Do I Protect My Laptop Data From Theft?

Encryption, done properly, is the answer.

Lose your laptop, and your data could end up in the wrong hands. I'll walk you through the best ways to encrypt your files, from simple zip passwords to full disk encryption with BitLocker, VeraCrypt, or Cryptomator, so your secrets stay safe no matter what.

Question: I travel a lot, and have sensitive data on the laptop I take with me that I need as part of my job. But I’m in fear of losing the laptop and that this data will fall into the wrong hands. What do you suggest?

I know how you feel. I also have sensitive information on my laptop.

I can handle losing the laptop, but thinking about the data in the wrong hands… well… that would be bad.

I’ve used different solutions over the years, and they all share one thing in common: encryption.

Why Are There So Many Jerks Online?

Trolls, jerks, dicks, and entitled rectal orifices everywhere.

Are people are getting ruder online? You're not imagining the jerks, but you might be missing the bigger picture. I'll discuss why the internet doesn't really create more jerks, and why the good people around you still outnumber them by a mile.

Question: You’re full of crap. That didn’t work.

This was a comment on my Facebook fan page in response to a tip I’d posted. Apparently, the feature I was discussing either hadn’t yet been made available in the commenter’s account, or they couldn’t find it. As a result, I was the one at fault for trying to be helpful.

Now, I get this kind of thing from time to time. On my website, abusive questions are ignored and inappropriate comments deleted. On YouTube, I can’t really keep up, but I try to do the same.

The poster of this comment apparently thought twice about leaving it up. Shortly after I replied, “A personal attack? Wow”, his comment disappeared.

But it got me thinking. Is the internet turning people into jerks?

Back Up Your Email Using Thunderbird

If it’s only in one place, it’s not backed up.

If your email only lives in your inbox online, it's not backed up. I'll show you how to use a free program to download a full copy of your email to your own computer, plus how to save your contacts. That way, a hacked account never means losing everything.

Many years ago, I received a panic-stricken email from an individual whose account had been hacked. He had lost all access. His panic stemmed from the fact that, for whatever reason, the account held the only copy of his master’s thesis.

It was gone, and there was no hope of recovery.1

Hopefully, you’re not keeping something as important as a master’s thesis only in your online email account. That’s wrong on many levels. But I’m sure there are things in your account you never want to lose, such as photos, correspondence, or other things you’ve exchanged via email.

The problem is, of course, that if it’s only in your email account, it’s not backed up.

Let’s fix that. Let’s back up your email.

What’s the Best Two-Factor Authentication Method?

When you have a choice, that is.

Not all two-factor authentication works the same way. Some methods are more secure, some are more convenient, and some leave you open to sneaky attacks like SIM swapping. Here's my breakdown of hardware keys, authenticator apps, texts, email, and voice codes so you can pick what fits you best.

There are several approaches to two-factor authentication, and it can be confusing. Some are simpler, some are more convenient, and some are more secure than others.

Let’s compare the various ways two-factor authentication, or 2FA, can be implemented.

Should I Avoid Windows Update? It Burned Me

Only if you like living even more dangerously.

A bad Windows Update can cripple your computer. Once it happens to you, it's tempting to swear off updates forever. I'll explain why that's the wrong move, and share one habit that makes any update failure, from Windows or anything else, easy to recover from.

Question: I recently took an update via Windows Update, and after doing so, my machine wouldn’t even boot. It took a technician hours to get it working again. That’s not something I can afford to have happen again. I’m avoiding Windows Update from here on out.

That’s a conglomeration of many questions and problem reports I’ve received over the years. The pace picked up when Windows 10 was released.

Windows Update has a reputation for occasionally causing working systems to fail. The good news is, it’s almost always a tiny percentage of machines affected. The bad news is, that’s no solace if you’re affected.

I absolutely sympathize. I can understand why you’d be skittish about ever taking an update again.

And yet, you should.
