Secure socket timeouts on Windows

by Andrei Stebakov

This issue has been bugging me for a while now, but I hesitated to post it since I can't explain what's going on. Every time I do any operation in Pharo related to secure socket connection I have strange socket timeout even though I can connect to the URL using web browser. This time I was trying to install latest pharo 7.0 via pharo installer and I got ZdcSecureSocketStream waitForDataFor: hang over trying to download https://files.pharo.org/get-files/70/pharo-win-stable.zip I can paste that link in Chrome and it can download it for me no problem also I can download it using curl. This issue only happens to me at work, when I do the same from home I don't see this issue. Anyway, I am at a loss here and wonder how can I debug and fix this issue. Wondering if something like that happened for you guys.

MetaLink after on a message with argument

by Peter Uhnak

Hi, I'm trying to install an #after metalink to a MessageNode that has an argument, however it fails because the bytecode is missing the argument (I think). Note that #before control worked fine, so I am not sure whether this is a bug, not yet supported, or am I doing something wrong. code (tested in P6.1): ~~~~~~~~~~~~~~~~~ Something compile: 'add: aNumber ^ 1 + aNumber'. after := MetaLink new metaObject: [ self logCr: 'after' ]; selector: #value; control: #after. " after uninstall. " ast := (Something>>#add:) ast. node := ast sendNodes first. node link: after. Something new add: 3. ~~~~~~~~~~~~~~~~~~~ error: [image: image.png] Thanks! Peter

Re: [Pharo-users] About describing the JupzterTalk installation process: Which Linux distribution are you using?

by Jesus Mari Aguirre

Hi Mr.Hirzel about opening SVG, files, in fact you can open SVG as a morph using ( ASVGMorph fromFile: 'file.svg') but first you need to install XML parser from the catalog. I think there is a missing dependency. so you can do self display openInJupyter:(ASVGMorph fromFile: 'file.svg'). About nteract and jupytertalk, I mean you need to install jupyter if you want to use other kernels but node kernel so your plan about installing only nteract+jupyterTalk wonn't be factible. I already have JupyterTalk working on Pharo 32 bits(windows) but it is harder to install than Linux or Mac because you need to install zeromq 32 bits...it is not so complicated but you need to install an additional dependency. In a few days it will be available in JupyterTalk repository. El miÃ©., 29 ago. 2018 a las 19:38, H.
