There were also other issues like supplied credentials not being honored. And even one of the hosts you mentioned did not supply a tarball in the same way as the others and was giving Dale problems IIRC. ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Re: [Pharo-users] Smalltalk Programming Competition

by horrido

It's been one full month since the GoFundMe campaign began. We've raised C$3,080 from 25 generous contributors. It's a good start, but we're still a long way off. In order to make the goal more attainable, I've lowered the funding goal again, this time, to C$20,000. And for the last time. You see, C$20,000 is necessary for the MVC (not Model-View-Controller, but Minimum Viable Competition). Anything less and we don't have an impactful marketing event. Please spread the word on social media. Please make use of your email contacts. Let's reach as many people as we can. I will bet dollars to doughnuts that not every Smalltalk fan in the world is aware of this campaign and programming competition. It only takes about 1,000 people giving a paltry $20 each to make this happen. How hard can it be? horrido wrote > So far, we've raised CA$2,400 from 18 generous contributors.

gRPC for pharo?

by Holger Freyther

Hey, I have collected some experience using gRPC[1] and would like to make clients and be a server from Pharo. After digging into the gRPC implementation it seems feasible[2]. Would someone be interested in collaborating on an implementation? cheers holger [1] An RPC framework using HTTP2 and sending Google Protobuf serialized data. It is used by etcd (distributed key value store, master election), apparently containerd (of docker) and the list is probably increasing. It has interesting load balancing support... [2] Wrap the C-API with with FFI, modify the gRPC protobuf compiler to generate Pharo classes with slots for the native types, create a polling Pharo Process to pull the completion_queue. With ThreadedFFI we could have lower latency and have a blocking call on the completion queue.

Re: [Pharo-users] Pharo 6 Freetype plugin stopped working after Windows update

by PBKResearch

More specifically, it was suggested (by Herby, I think) that it is a timing problem with Windows loading several .dll files at the same time. If the loads complete in the right order, all is well; but in some cases, loading one .dll takes a bit longer, and it is not available when called by another. If correct, this explains why it happens intermittently. It also explains why it is so difficult to debug.

Re: [Pharo-users] XML support for pharo

Hi Oswall, for processing, take a look also at these three projects.
