Now, the general idea and implementation of Tide was simple and it shouldnât be much work to make it run on Pharo 6.1 (somethings changed, but I do not think too much in that area). There is still the problem around Amber, but thatâs more a question for Amber list, I have no idea of its current status (and on how the amber part of tide would work). cheers!

State of Tide / Amber ?

by in_pharo_users＠nym.hush.com

Dear List, I was trying to set up Tide / Amber. I found a Tide version for Pharo 3, but optimistically I tryed to set it up with Pharo 6. Then I went to 5, 4, and then I used 3. I set Tide up according to the instructions, and well, the JSON interface seemed to work fine. This may not be the concern of this list: Then I tried to get Amber running, but I failed. I found no description thatI was able to follow to success. What is the state of Tide? Is it still actively supported, or has it either vanished into a proprietary enterprise or been abandoned? If it went to proprieary, is a successor still available? Has it been abandoned in relation to technical or other shortcomings of the concept? Can anyone help me to get Tide running on Pharo 6? Kind regards, basket

Pharo-users] SSL Exception when installing DataFrame

by Baveco, Hans

I get the same error when trying to install other packages (e.g. Cruiser) (SSL Exception: connect failed [code:-5]), Also when trying to do a software update from the System menu. This is Pharo 6.1 on windows 7 It might be somehow related to Iceberg: the Iceberg item in the World menu has gone after trying to update?? Hans

Something is happening...

by Marcus Denker

Hi, There is something odd happeningâ¦ or better: There is *a lot* happening. Just one example: for the Newsletter, the original idea was to send out once a month a post with 3 things, some of them recycled (e.g. pointers to existing projects, re-use âsuccess storiesâ, things like that. Now already some months ago I had to add âand here are some other interesting announcements, blog posts, videosâ. But this month, the list of things for the newsletter TODO list contains over 60 entries. With the exception of maybe 5, these are just things that happened between sending the February newsletter and today. Newsletter March should be ready till this thursday, I hope, subscribe or read the oder ones here: http://newsletter.pharo.org <http://newsletter.pharo.org/> Marcus

Hello, I can not manage this syntax that seems to be simple.
