As a computer scientist, I prefer the design of Ethereum over most blockchain technologies. It as a significant improvement over older peer computing compensation models. Ethereum is a peer computing network with a fair compensation algorithm.
However it is not perfect. The people behind Ethereum know that and are moving to improve that.
Ethereum 2.0 will be a new blockchain based on Proof Of Stake. Proof Of Stake means the companies adding transactions to the chain must offer some of their currency to be given a transaction to process. If they are caught cheating the system they lose their stake.
Personally I prefer this model for many reasons. The biggest benefit is the reduction in compute power needed to process transactions. Bottom line – it is better for the environment.
I’m hoping this gets done in 2019 and gains a strong following.

Did you know you can tell Selenium IDE to execute certain commands only if a specific element exists on the page? The if element exists trick makes your web app testing scripts far more interesting. Here is a quick example using Selenium IDE 3 — the “new” Selenium IDE.
Log out a standard user
In this use case a WordPress multisite standard user is logged in. We can only execute our commands if we are a super admin. When trying to open a URL that is only available to the super admin an error page shows up. Thankfully this page also comes with an easily identifiable body ID set to error-page.Read More
After a year-long hiatus, one of my favorite web app testing tools is back. It is nice to have Selenium IDE back as a viable option. Yes, it is similar to the old version. No, it is not perfect. It is a lot easier to use than nearly any other web app testing option available.Read More
In what has become a nearly annual tradition, WordPress has released yet another update that broke thousands of plugins across the Internet. As usual, they claim this is in the best interest of security. Thus the breaking change was done with ZERO notification to developers. It was also forced onto most sites as a “security patch release” which will update any site that does not forcibly stop automatic updates.
Communication From WordPress Core Is Horrid
While I don’t have an issue with breaking changes for true security issues, what IS a problem is pushing out a change with almost ZERO testing to millions of websites with ZERO communication. They gave absolutely no warning to thousands of sites that this “update version” was coming and that it would knowingly break things. They did not communicate to site owners so they could block updates. They did not communicate to plugin or theme developers so they could come up with new releases.
A quick intro to Vue. If you are a jQuery fan I highly recommend looking into adding Vue to your developer toolbox.
