Persistence of data across sessions
by graham telfer Sept. 6, 2011

Sept. 6, 2011

Hi there, I completed the Bank Account tutorial written for Squeak. It worked fine but I have a question about persistence of data. After I built the bank account and gave it a balance history I saved and quit. Later I wanted to go back to it. The account and its details were gone and I could only create a new account. How is data saved across sessions in Pharo?

I made something that accesses the standard crypt(3) and libxcrypt libraries with FFI. I've only used it on linux. I have made a Gemstone port. The package is named PasswordHashingFFI and is in the Cryptography repository on squeaksource here: http://www.squeaksource.com/Cryptography With them you can do md5, DES, sha256, sha512, and bcrypt. The Cryptography repository has native implementations of md5, DES, sha256, sha512. I don't know about the security implications of using FFI vs. native vs. a plugin.

Status of crypto libraries for Pharo?
by Larry White Sept. 4, 2011

Sept. 4, 2011

Hi, I'd seen some mail in the archives saying that the old, Smalltalk native encryption libraries were abandoned and new libraries should wrap some standard implementation. I'm looking at the moment for symmetric algorithms and an md5 hash for storing passwords. Does anybody know the status of these things? Thanks much. Larry

Node.js seems to be a wrapper around a C-Library that provided async IO for all platforms. Wouldn't it be possible to provide binding for the C part of Node-JS and use that for async/Event based IO?
