@Rolf Kalbermatter, I will be redoing the export today based on the new scripts, if they work. So if you committed code recently, it will get included. I think you are the only one working on any code at the moment. I will add you as a collaborator on the repo so you don't need to fork. Once the conversion is complete: Make a branch on the git repo. Checkout the branch Do a file diff between your local SVN and the Git branch. Copy over the changed code from SVN to Git. Commit the branch. @LogMAN, unfortunately GitHub does not have a good way to group related repositories, so they visually seem to belong together. The only distinction is organizations. There's the Project feature, which I think just helps with development workflows. Having numerous OpenG repositories will make this a bit messy. But I guess there's no way around that. It seems GitLab and Bitbucket have a slightly better approach with this.

Thanks @LogMAN. After I get paying work done, I will try this out. For anyone else following along. If you are currently an OpenG developer ( @Rolf Kalbermatter?) and want to be added to the OpenG team on GitHub, send me a PM.

We can create a VIM array package for OpenG that is separate from the other array package. We could call it something else. So it could be distributed in 2017. Currently the entire OpenG sources are in a single repo. So you have to build everything in one LV version (2009). If we made each package its own repo then it could have its own LV versioning roadmap separate from the whole. See discussion here.

Well, I was hoping someone would continue the discussion, so great! We can redo the conversion. But is it really that critical to migrate the history intact? I question the need for that. If not we can start fresh. Authors - The conversion I went through had the ability to add email addresses to the author names. I just don't know what the email addresses are for the authors in Sourceforge. I've attached the author list if anyone wants to help flesh out the email addresses.Then we can rerun the conversion. Branches and tags. - I looked at the SVN repo and there's only one branch, SVN does not due branches well, so I'm not surprised nobody used that feature. There are a few tags and those are very old, circa 2007. Not sure if anybody cares about those. It seems the tagging procedure (if any) was dropped long time ago. You should be tagging with every release but that does not appear to have happened. One repo - The original SVN was a single repo, this is why i kept it the same. The conversion is a lot simpler. Breaking up a single SVN repo into multiple GIT repos and keeping the history intact seems complicated if you have commits that include files that cross library virtual boundaries. If you can think of a way to do this, that would help. Commit messages. - The commit messages are all there. It's the URLs inside the messages that are not pointing correctly, but I'm not sure what they should be point too and how to fix that during the conversion. Also, what if SourceForge changes the URL structure later? Again, is this important? Well, this is a good starting point. The alternative is to start fresh and create multiple GitHub repos, with the latest revision of the source. Then the SVN repo can be an archive if anyone wants to get at it. I welcome your help if you can create scripts to solve some of the above problems. authors.txt

I followed these instructions: https://www.atlassian.com/git/tutorials/migrating-overview I did that because my goal initially was to export to bitbucket, which I did. Then I changed my mind and decided that Github would be better for a community project like this. So then, since it was already in a Git format it was simple from within the Github website to select "import" and just point to the Bitbucket URL. Note: Those instructions work best if executed from a linux machine. I quickly spun-up an Ubuntu VM to do this.

I've exported the OpenG sources from Sourceforge SVN to Github. It's located here: https://github.com/Open-G I'm hoping this will encourage collaboration and modernization of the OpenG project. Pull requests are a thing with Git, so contributions can be encouraged and actually used instead of dying on the vine.

Not having looked at your code, do you think this should go into OpenG? How can we improve OpenG? Where is the OpenG repo?

I'm glad to see all these frameworks being bashed about. I like to read opinions from people who have tried the various frameworks and can compare based on real implementations. Not example code. Just came back from the US CLA summit (videos being posted to LabVIEW Wiki soon). Apparently there's YAF (Yet Another Framework) being used by Composed Systems and it was presented at the CLA summit: https://bitbucket.org/composedsystems/mva-framework/src/master/ It seems to be an actor-framework extension. Framework on top of framework? Jon argued that the complexity of a framework is secondary to the ability of a framework to allow certain programming concepts to be used during development. One being, separation of concerns. if you look at slide 4, Jon vehemently disagrees with that statement. In other words, you should not look at a complex framework and be afraid of it. Don't focus only on how easy it is to learn or get going with it. Question to you. What is important in choosing a framework? Here's a link to the slides: https://labviewwiki.org/w/images/2/24/Design_for_Change.pdf

The following slide was just presented at the CLA summit:

All of this spam was created a long time ago when the site was more vulnerable. The wiki has been locked down since then, and this should not happen again (but some get through). I deleted the first list of pages you mentioned. The uploaded images are tedious to delete because there no simple tool I've found to do it on a mass scale. Since they're not linked anywhere then they don't do much harm except use up server space. It seems you have time. So I will connect with you directly offline to give you some rights.

The OP didn't clarify his requirements so we could all be wrong. But ya, all you guys say is true. - Thanks. My intent was to start the conversation, not to provide the best solution. I just wanted to show how the delete from array works and to provide some visuals.

I dunno. Your question is not clear, but let me take a shot. This example deletes the last 3 elements of an array of strings. Don't forget that array indexes start at 0, not 1.

@Tim_S, the OP makes a valid point. All you say is true, however, the link remains broken and the person packaging the OpenG tools should either fix the link and provide the documentation, or remove the link from the package build.

We're starting to add the back catalog to YouTube. NIWeek 2018 videos are also up.

Mark of course has the originals and always will. So that's not an issue. However, nobody cares about some LabVIEW videos. Yes, that's a great idea. It's a wiki so anyone can add them if needed. Feel free to contact them or edit the page. That's because the videos are unlisted. We are doing this so that in order to view the videos you have to go to the wiki page as the entry point. This way they are kept within the community. This was the compromise to balance accessibility. We can deal with that issue if we hit it, which I doubt we will. Considering the videos are unlisted and we have approval by the presenters.

Hey folks. this year we're trying something new. All Videos for NIWeek 2019 can be found here: https://labviewwiki.org/wiki/NIWeek_2019 Feedback welcome. Thanks to @Mark Balla and other volunteers for recording the videos. Edit: We're starting to add the back catalog to YouTube. NIWeek 2018 videos are also up.

I don't have the time or desire to figure out how to automate this. But it's cool that trick works.

Is this error message coming from a VI that you are running on the RT target? Have you tried using the NI Distributed System Manager? I use that to debug Ethercat issues. When you switch to Active mode using NI DSM, it works pretty consistently. Unfortunately the NI Ethercat driver is a load of poop. Soft reboot of the controller usually fixes things up.

No.

I have no idea. That seems to be a URL in the old format which died a log time ago. The post probably still exists but was converted to a new URL format and there is no redirect.

What happens when you create a page? Do you get an error or something?

I think it's solved now.

Thanks for the interesting conversation. I've resolved the issue however, in a roundabout way and by cleaning up my code. The UDP communication code in question is a model written in LabVIEW running on VeriStand, which is essentially a bunch of LabVIEW RT timed loops running on a Phar Lap target. So the model essentially opens a UDP connection, sends the message, then closes the connection. This is done at a rate of 50Hz. I changed the code so that it opens the connection at the start of the test and the model just continuously sends the message at the 50Hz rate, then at the end of the test I close the UDP connection. This resolved the issue because now the ARP is not sent anymore, like at all. Well, maybe at the start? But I haven't checked that, so I should do that later. The explanation I can come up with is, I was closing the connection every 20ms, so the OS considered the port closed, so it took that time to do the normal housekeeping of sending the ARP? But since the port was always open to a known IP address (and thus mac ID), it didn't need to do the ARP. I don't know, just my guess. Ok, so bring on the comments about, why I would keep opening and closing the port. Bring it on, I can handle it... 😀

Looking at this post by an NI employee. It seems that the ARP table cannot be statically defined on Phar Lap.

I'm using LabVIEW to do all this. So not sure how to do RUDP. I'm using UDP because of the low overhead. But maybe I can still get the throughput with other methods. I will have to experiment and see. I've just never considered that this issue would come up at the slow rate I'm using. Edit: It seems like ARP has a configurable timeout. Since my test only lasts for about 2hrs. Perhaps i can do an ARP at the start of the test and set the timeout longer than 2hrs. Now to figure out how to configure this timeout in Phar Lap.
