Why open hardware needs open software - and more from Wayne Stambaugh of KiCad - SnapEDA Blog
Some of the commercial EDA CAD tools are very expensive. A lot of people cannot afford or justify the cost of them. This effectively limits the number of users who can take advantage of design released under an open hardware license. And if you’ve been around long enough, you also know how these tools will often change their file formats. So then you can’t open designs with the old versions. We’ve all been through that merry-go-round.

ESD & Thee
More on snake oil. Wearing latex gloves or finger cots will not aid or abed the prevention of ESD. Think about it. By the time you place latex or other magic gloves on the gloves are at the same potential as your body. They will not generate an additional charge nor will they aid in dissipating a charge. Latex gloves and finger cots serve a very important purpose both in a surgical operating room and in a super clean room where electronic assembly takes place. Our hands, even when washed thoroughly, contain oils and micro contamination. Latex serves as a barrier for contamination but not a very effective barrier for ESD. Which at this point are negligible. I have worn my share of latex as well as other conductive gloves, I have worn my share of special conductive booties with cute tails one tucks into their shoes. I have also treated my hands with special conductive lotions as well as walked miles of floor space covered with ESD wax. I have calibrated countless ESD workstation mats and devices to test wrist straps before personnel touch ESDS devices. This was all done in very, very specialized manufacturing areas. This was not your kitchen table or computer room. I have in turn built many computers on my kitchen table and in my computer room without a mishap related to ESD. My success in this area is not attributable to super special precautions, snake oils or magic but rather applying good workmanship habits. Think about ESD, think about how to avoid ESD and you will do just fine.
