Scripting for the rest of us

I have heard people say that everyone should know how to code. This struck me as wildly unlikely. People are just to busy and have too much on their plates to all become software developers.

haveibeenpwned now checks passwords too

There is a great tool called haveibeenpwned put out by Troy Hunt. You can enter an email address or username into this website, and it will tell you if it has been involved in a data breach.

Obviously, it is far easier to remember techielibrarians.com than a whole string of numbers. That is why we have DNS. DNS is simple in concept, but can provide some complications in practice.

Open source software and the values of librarianship

The Lebanon Public Libraries in Lebanon, NH run on free and open source software. This software accounts for about 95% of all the software that we use. This is not the norm for a library, but it should be. This is software that is in agreement with the values of librarianship. It allows us as librarians to serve our patron’s without the compromises that come from proprietary software. There are many benefits tofree and open source software. [Read More]
