About Dong Knows Tech

Hello! You’re looking at yours truly.

Hi everyone, Dong Ngo’s here! (Weird last name? Dong “Know” will do.)

Who is Dong Ngo?

You probably remember me as the “router guy” at CNET during its heyday. Fair enough! From late 1999 until mid-2017, among other things, I reviewed networking gadgets there.

What you sure don’t know is how my obsession with technology started.

As a teenager, I ran into a piece of repurposed packaging cardboard with a life-size QWERTY keyboard drawing on it. I used it to practice typing with all ten fingers, just for fun. (There’s more to this, but that’s a different story.) Years later, I got a hold of a real keyboard with a computer attached to it, and my life changed forever.

In a way, that piece of cardboard was my first touchscreen. Now, like many of you, cutting down on screen hours is my daily struggle. So, I’ll make sure your visit to Dong Knows Tech is worth it. I’m not going to waste your time!

A bit of personal stuff

I was born and raised in a tiny village in North Vietnam, among paddy fields. The part just before I arrived had been ravaged during the American war. We literally had nothing, tech- and non-tech-wise.

I spent most of my childhood as a farmer, without electricity or running water, and I had no experience with shoes until I was 17. Now I live with my little family (wife and two toddlers) in the San Francisco Bay Area. It has been a long and memorable journey to a real American dream.

English is not my first language. (Not even my second, or third, so to speak.) That said, once in a while, please excuse my French! 🙂


What can you expect from Dong Knows Tech?

“This Dong guy knows tech!” is something you might notice. But that’s not the point of this website. (“Dong Knows Tech” might or might not be an alternate way to pronounce “Dong Ngo’s Tech.”)

What you should pay attention to is that I do my own research and review products independently.


  • I don’t take money to say good (or bad) things, nor do I say good things so I can sell something.
  • I don’t publish just marketing materials, specs, or commentaries and call it a review.
  • I don’t steal content from other websites in any form whatsoever.

Dong’s promise

After years in the mainstream business of tech news and reviews, I understand how things work and the amount of shenanigans folks have to deal with online. That said, here’s my promise:

My reviews and how-to posts on this website derive from my thorough first-hand testing or real-world experience. You’ll find here no bullshit, no click baits, no patchwriting, no pointless listicles, and no product pushing.

I don’t have a quota. My only pressure is the desire to share what I know to help make your life easier, one appropriate tech decision at a time.

In short, “Dong Knows Tech – And THAT’s good for YOU!” is real. I mean it.

(That is, of course, if you spend time and read what I have to say. Else, it’s only good for somebody else!)



The world of tech is fluid — things can change quite dramatically over time. You’ll note that I often update many of my posts, but nobody can keep tabs on everything or test every scenario.

That said, the reviews and how-to posts on this website are accurate to the best of my knowledge but not necessarily free of errors or mistakes.

The point is: I can be wrong.

(And I’d be happy to share over a drink the stupid mistakes I’ve made, tech- or non-tech-wise.)

So, use the content at your own risk. I assume no responsibility for any consequences that might arise from your consumption of the information posted here.

(But I can tell you for sure that it’s OK to make mistakes as long as you learn from them. In that sense, a mistake is better than nothing at all.)

How can you support Dong Knows Tech?

The devil is in the details. Running a tech website, especially one free of bullshit, involves so many things and substantial financial costs. It can be time-consuming, too.

And I’m doing this all by myself, down to the look and feel of the site itself, in addition to taking care of my growing family. (Yes, I have a day job.)

I didn’t start this website to make money. It’s been a labor of love, as you might have noticed in the little details. But I do hope someday I can make it my full-time job and possibly even more.

That said, if you want to support my work, there are three things I’d like to ask of you.

  1. Please take your time and really read my articles, especially the explainers and how-to, instead of skimming over them and then sending me questions, hoping to get a quick, easy answer. (Seriously, you’ll note that I work hard on the writing, it’s only fair that you do your part on the reading.)
  2. When you run into a typo in an article, please report it by selecting (highlighting) the text in question and hit the red button to the right of the screen. Or you can call that out in the comment section below each post. (I proofread myself, and that’s very challenging.) Thank you!
  3. Please turn off your adblocker — ads help pay for my expenses — and send useful articles to your friends. If you’re so inclined, feel free to buy me a coffee. (I live off of coffee, that’s true.) Also, when you run into sites that reuse my materials without disclosing the source, please let me know.

I welcome suggestions and appreciate constructive criticisms. Please keep them coming!
