I was just reading this Seeking Alpha article about Facebook and saw the attached image, where for a while “link sharing” on sites like Twitter, Facebook, and Pinterest overtook search engines in terms of “share of website visits,” but in 2017 search engines once again overtook sharing. The question is, does this mean that fewer people are using those social websites, or fewer people are sharing and clicking on those links?
As a note to self, I added SSL/TLS certificates to a couple of websites using LetEncrypt. Here are a couple of notes about the process:
- Read the LetEncrypt docs
- They suggest using certbot
- Read those docs, and follow their instructions for installing the packages you’ll need
- Make sure your server firewall rules allow port 443 (You may get an “Unable to connect to the server” error message if you forget this part, as I did)
- After making some backups, run this command as root:
Interesting discovery of the day: Even on an iPhone -- which was supposed to transform the "browsing the internet on a phone" experience -- almost all of the websites I have bookmarked and visit on a daily basis are WAP/WML websites, including WAP/WML versions of the NY Times, SJ Mercury News, Facebook, Google News, and ESPN.
Here's an interesting link about "Who has the most web servers?" It only briefly touches on guesses for the number of servers Google and Microsoft have, but they provide interesting numbers for companies like 1&1, Rackspace, and a few other big names, based on this "Netcraft hosting provider server count".
It used to really amaze me that some people always knew immediately when there were new updates to software applications -- and this goes back to the old days when many applications weren't self-updating. I always wondered how they knew about these software updates so fast. With today's RSS feeds it's pretty easy.
