Since Novembmer ‘21 update, Active Directory new conditions may make it raise a CONSTRAINT_ATT_TYPE violation affecting other products.
I’ve been using Gentoo Linux for 20 years. Why? Because I cannot live without Linux and I haven’t found any Linux distribution that I like so much. Here I tell why.
So let me put it clear from the first line: trusting invalid certificates is wrong.
And now I will explain why it’s wrong and why there are few excuses for it.
We are talking here about certificates for SSL encryption, which serves basically two purposes:
Privacy — data is transferred encrypted and can only be decrypted by the intended recipient and not a third party wiretapping the line. Authentication — making sure the receiving end that will be able to decrypt the data is who they claim to be and data is not diverted to a different receiver by a third party with access to manipulating our transfers.
Let's start with a bit of history.
Casim.ir is a URL shortener developed by Nicolas Hoizey in PHP eleven years ago (stylized by then as Cas.im/ir) with the intention of creating a light and simple URL shortener.
About seven years ago, I installed it to create my own private URL shortener at chu.so and some other open and public ones with some modifications on Nicolas's project.
Shortly after, I started contributing to the project with improvements and bugfixes and almost instantly Nicolas gave me direct write permission.
So far, I've been using WordPress for this website. It's a very powerful and complete blogging software, with a lot of plugins, themes, search engine optimizations, etc. It has been in the market for more than 15 years and continues to be actively developed.

On the other hand, I haven't updated this blog for two years, with a single entry in the last 5 years.
Every time someone asks if I have heard about Bitcoin or tells me they want to invest, there are so many things that I think I could tell and so many links that I would like to share, that I thought it would be better to compile everything in a blog post. And, what the hell, nowadays you're nobody if you do not have a blog post about Bitcoin and which topic could be better to wake up my blog from its two-year lethargy than the bubble of the moment.
