Re: [Pharo-users] Updating singletons

by Steffen MÃ¤rcker

Hi Konrad, sorry, I might have misread your question such that it was about updating references to an obsolete object. However, there is another fun possibility to figure out that a change happened that does not involve configuration - though, a bit hacky. ;-) You could write the accessor method such that it recompiles itself with the first access after loading new code. For example: > Singleton>>uniqueInstance > instance := self class new. > self class compile: 'uniqueInstance ^instance'. > ^instance Best, Steffen Am .01.2019, 18:04 Uhr, schrieb Konrad Hinsen <konrad.hinsen(a)fastmail.net>: > Hi Steffen, > >> Have you considered to yield (an) proxy object(s) instead of the >> actual > Singleton in uniqueInstance?

Re: [Pharo-users] Discord Server invite is now private because of spammer

by Dimitris Chloupis

After discussing it with Stef and Esteban and of course Ben . we reached the conclusion to have only a few days keeping the invite link private. After that it will become public again to make it easy for people to join without any hassle. If the problem reappears we can discuss whether further action is needed, in the meantime I will try to ban members generated by the bot. I wont be deleting it without consulting you first. Admins please refrain from creating additional invite links, one should be enough and will make everyone life a lot easier. The new link has no expiration date. Making the invite link public means that the links to the link , like the one on the website , will have to be updated to the new one. I do not have access to those places so people that do will have to update it. I will make the link public in this thread in a few days. in case the people that are responsible for sharing the link are not admins in Discord and they cannot access it. Again I apologize for the inconvenience but it was a necessary action to minimize the problem. I am at your disposal for any further clarification and assistance.

Re: [Pharo-users] Discord Server invite is now private because of spammer

by Dimitris Chloupis

I leave the handling of the invite link up to the admins. I made several of you admins as experienced members of this community so that you can handle situations like this. As always my policy has been to make the first step and let others do the rest. The incident is not one, I had to ban 3 members , obviously dummy accounts for the spammer, to have to delete the invites. When it was first recommended I refused to do it but as they say, third is the charm. If you use several invites there will be no way to know which invite was used by the spammer. I do not think disabling the embeding of links is a good idea, cause we heavily rely on them , especially for helping newcomers. It will also make little diffirence to the spamming because the bots wont care and continue spamming. Those members are clearly bots because the same exact message is post each time and I doubt that someone goes to this trouble to do this manually. In any case, I leave it up to the community, if you want the old method and endure the spamming that's up to you. I do not have the time or desire to do heavy moderation anyway, so its unlikely any method will be future proof.Any direction you decide to follow, you have my blessing. In any case spamming is far from Discord exclusive problem and it has happened even in this mailing list. So there is no ideal solution.

Change the name of the programer in the image

by Alidra Abdelghani

Hi, In a fresh Pharo image, when you edit your first method the system asks you for your name. Sometimes, I share some images with my students so I wonder if it is possible for them to enter their name instead of mine when they edit their own code? Thanks in advance Abdelghani

Discord Server invite is now private because of spammer

by Dimitris Chloupis

Hello people , as you may or may not be aware we have a spammer that posts links to sexual content sites. This is of course an unacceptable situation so I had to delete all existing invite links. This means that from now on I will not allow members to create their own invite links and I will also not allow more than one link to be active at a time so I know which link is compromised. The invite link will no longer be public but shared privately only by Admins to people who are already active here and it will be shared only through personal emails and messages. I have also raised the level of automatic moderation , from now on new members wont be able to post in our server unless they have a verified email with Discord. Also all messages are automatically scanned by Discord from now on for improper behavior. I am sorry for this inconvenience but its all part of having a very active community, it was just a matter of time till we attracted the attention of spammers. This does not affect our almost 1000 existing members on Discord server so if you already a member you have nothing to worry about. This affects only new people who like to join. If you are new and you like to join I will send you an invite link ONLY if you are active in this mailing list and after you are ask for one. You can use this thread by providing your Discord ID (you get this when you register with discord) and I will send you a personal message in Discord with an invite link. By active I mean that you have substantial participation in this mailing list which means at least 3 posts. If you are a member or admin and post the link publicly , its not a problem, but please be aware that if the link is compromised then I will delete it and create new making new members unable to join with the old one. So use the link wisely. You can also contact one of the other admins , if you know who they are and they know who you are. If you dont then use this thread and be patient. Once you join there are no restrictions or anything else that will make your life not easy. Happy Pharoing ;)
