yes, that's why I spent one full day making those messages configurable. as soon as we can run the build process again, our pharo vms will have pharo messages :) Esteban On Tue, Feb 5, 2013 at 10:00 PM, StÃ©phane Ducasse <stephane.ducasse(a)inria.fr > wrote: > thanks for reporting it. > Today in a lecture the students got problem on Ubuntu they got another > message "there are three ways to use a squeak-imageâ¦." > > Stef > > On Feb 5, 2013, at 9:58 PM, Steve Graham wrote: > > > I downloaded Phar 1.4 one-click onto my Linux Mint system.

thanks for reporting it. Today in a lecture the students got problem on Ubuntu they got another message "there are three ways to use a squeak-imageâ¦."

Error installing version 1.4

by Steve Graham

I downloaded Phar 1.4 one-click onto my Linux Mint system.Â When I ran the .sh file, I got the following error: could not find module vm-display-X11 Aborted I foundÂ that file in the path though: steve@steve-Satellite-L555D ~/Desktop/Pharo-1.4-one-click.app $ find . | grep vm-display ./Contents/Linux/vm-display-null ./Contents/Linux/vm-display-X11 steve@steve-Satellite-L555D ~/Desktop/Pharo-1.4-one-click.app $ Any ideas? TIA, Steve

Re: [Pharo-users] We would love some help

by Miguel Moquillon

In fact, the one-way hash functions (MD5, SHA-1, SHA-256/512, ...) are not for password encryption, they are for computing a digest of messages in order to ensure their integrity. These functions usually suffer of recognizability and of computing speed and hence they cannot be used to encrypt passwords. To encrypt passwords, some features are added to these well-known hash functions in order to generate more entropy in the computing of the digest: salting and stretching. For example, the algorithms used in the Unix systems are variations of MD5 and of SHA-256/512 using these two techniques. In another way, in effect, there is a family of cryptographic algorithms that is more suited to encrypt the passwords: the adaptive key derivation functions in which we can find bcrypt but also PBKDF2 and scrypt. (OpenBSD, an operating system obsessed with security, uses bcrypt as its default authentication mechanism). Beside the cryptographic functions for passwords, there is also some recommendations to follow. Among them: - prefer passphrases to passwords: the user can more easily remember them and they add inherently more of entropy, - for each authentication failure, multiply by 2 or more the time between two retries.
