👍 #801 – How Much Can I Trust Information on the Internet?

Confident Computing #801 - How Much Can I Trust Information on the Internet?

Featured

This week's featured article is another that I've chosen for its timeliness: how to know what's accurate online. Particularly these days knowing what to believe -- knowing what to trust -- is critical to making informed decisions about how to go about living your life.

I don't think it's overstating things too much to say that knowing what to believe can even save your life, and the lives of those around you.

Please, please, please, approach the information you encounter online with a skeptical eye, and only pass along that which you have taken the effort to know is accurate.

"Https" doesn't mean everything most people thinks it does -- we'll look at one of the ways that https can be misleading and not at all secure.

Speed. We all want more, especially now. Here are the things to keep in mind.

"Internal Server Error" -- it's probably not your fault. Probably. Smile

Another "test" webinar

I continue to play with doing more live events, and ran a small audience webinar over the weekend as another test. I'm happy to say that for the most part things worked well. If this interests you at all you might want to keep an eye on my Twitter feed, or my Facebook page, for more last minute announcements. I hope to settle on a regular schedule in the coming weeks, and will announce that here.

A recording of this week's webinar is here: Setting Up Macrium Reflect Free (Webinar #2).

Peace. Stay healthy,

How Much Can I Trust Information on the Internet?

I'm a computer science student, and I'm confused about the extent to which I should rely on the internet for the information about computers. For example, if we take the term “IP address,” then a lot of information has been provided on (for example, Wikipedia), which is a lot more than what is written in the recognized books. My question is how much should I rely on the web for such technical aspects?

I originally addressed this question in an Answercast back in 2012.

It was an important question then, but oh, my, it's amazing to consider how much more relevant this question has become since then. Of course, it's not just about technical information, but also about information relating to just about anything you can imagine.

You know – like the news.

I'll look at the quality of information available on the internet and offer a few suggestions to help sort out what is good and what is questionable.

How Can an Https Website Still Not Be Secure?

I have heard that going to an “https” website isn't a guarantee of security, and that some data I enter might still be unencrypted. How can that be? I thought https was encrypted and could not be sniffed?

You're right: https is encrypted, and cannot be sniffed.

However, bad website design can foil everything. In fact, I'd go so far as to say bad website design can easily foil everything.

To really understand what can happen, we have to understand a little bit about how the web works, and what happens when you visit a webpage.

Why Doesn't My Internet Speed Match What I'm Paying For?

Through my ISP, I've contracted for 100 megabits per second of internet speed. The maximum speed that I can get, however, is about 30 megabits per second through WiFi. When I connect to the router via a LAN cable or I have the laptop right next to the router, I get 80 megabits per second, which is close enough for me. I've read that unless the WiFi signal is very strong, you never really get the advertised internet speed.

But my question is about the following: my ISP recommends one measure the speed using one specific link and their web page. And that speed is measured downloading a large file from a server that is some 100 km from where I live. I find that when I use one of the many speed-testing sites, I get about the same results if I specify the same server my ISP uses; when I choose servers which are much further away (like another continent), the speed sometimes slows to a crawl. So it would seem that there is a somewhat inverse relationship between the effective internet speed and distance. So my question is, what's the point of getting ultra fast internet when it hardly ever gets anywhere near the speed promised by the ISP?

There are several interesting issues here I want to cover. Internet speed confuses a lot of people, mostly because it combines many different issues under a single heading.

So, let's talk about your 100 megabits.

What's an "Internal Server Error" and How Do I Fix It?

I'm trying to download software from a specific site. No matter what I try to download, I get this error message:

Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator webmaster@******.com and inform them of the time the error occurred and anything you might have done that may have caused the error. More information about this error may be available in the server error log.
Additionally, a 500 Internal Server Error was encountered while trying to use an ErrorDocument to handle the request.

How is this resolved?

I'm very familiar with this error. I see it all the time when setting up or making changes to websites.

The good news? It's not your fault.

The bad news? There's probably nothing you can do.
