A question for the creators of XO
-
Hi @olivierlambert,
Can you tell me which JavaScript features are not available in Ruby or PHP? -
@jasonnix On the other hand, why should one use Ruby or PHP when Javascript fits the projects requirements? Javascript is a State of the Art development environment with a lot of available and capable resources. According to the (maybe biased ) conclusion of the State of Javascript 2022 survey, JavaScript and TypeScript are more vibrant than ever. You don't normally change horses in projects like this without good reason.
Would love to understand why you are asking though.
-
Thanks @gskger.
I asked because languages like PHP and Ruby are very popular in the web and have many developers. you said "Javascript is a State of the Art development environment with a lot of available and capable resources.", I want to know what features are there in this project that PHP or Ruby can't do. -

A feature comparison (or retrospective evaluation of the decision) is not needed anymore for a project that already choose a development environment years ago, engaged people with the required skills and build a deployment process around a commercial product.
Could XO be build with PHP or Ruby? Probably yes. Does it add value to the product? Probably no, because it working just fine with Javascript as a future proofed development environment.
I apologize if I still not get why you are asking.

I start to wonder if we are talking to an actual human or an LLM I still don't get the point of this discussion.

Hi @olivierlambert,
No, I'm not a bot. I asked it because I need your experiences. I want to make a panel for Xen. -

Hi @olivierlambert,
No, I'm not a bot. I asked it because I need your experiences. I want to make a panel for Xen.So you know how to program with PHP and Ruby and not with Javascript, so the question is really "Why can't this be rewritten so I can help?"
-
@DustinB you are really asking to rewrite the full XO project in PHP so you can contribute? or did I miss something
since there is only 136K line of code to rewrite, maybe it can be a good weekend project ? -

Javascript and node.js seem to be more popular than PHP and Ruby:

I dont think a lot of ppl use PHP anymore, its a good language to get started with coding but its not something you want to run in mission critical production environments.
I think node/java is a good choice for this project since it can be used for both backend and frontend, it runs smooth on pretty much all distros that supports it and now days a lot of ppl know node/java so it is easy to find ppl to code for you.
-
PHP is still widely used and there's some neat frameworks. But again, seeing the language only from its popularity is wrong. It's an entire "ecosystem" you need to look at:
- being reasonably good for your existing team (ie if your team like the language/framework or not, doesn't matter if it's personal taste, it will have an impact on the team performance)
- if the language is not too niche to easily find more devs when you grow
- that the language pros are worth it in your context (ie we don't specifically need something too complex to learn like Rust to build an UI): all about usage context. It's obviously different for an hypervisor or a toolstack
- there's a big enough ecosystem (libraries, packaging, sec updates etc.)
And probably other things I forgot. So as you can see, there's not one reason to adopt a language, but many and most of all them depend on the project and people around it.

If by
make a panel for Xen
you mean a dashboard to visualize or controll a Xen-enabled host or the virtualized guests, I would suggest to start learning about XAPI or better XO API.How you design or implement such a panel is up to your ideas, capabilities and choice of the tools you are familiar with, be it Ruby, PHP, Java or Javascript. Also check out XCP-ng Center which is maintained by @michael-manley in a community effort and uses C# to controll Xen-enabled hosts.
-
Hello @olivierlambert,
As far as I have heard, JavaScript and Java programming languages โโare insecure. I don't know how true this is. I know VMware vCenter uses HTML5 in one mode, although some features are missing in this mode. -
Hello @gskger,
Thanks again.
In my opinion, one of the mistakes that Vates made was removing the XCP-ng Center. Citrix XenServer still supports XenCenter. -

In my opinion, one of the mistakes that Vates made was removing the XCP-ng Center. Citrix XenServer still supports XenCenter.Vates didn't remove it, its a package maintained by the community, and only the community. Vates has their own project that they are building and maintaining.
-
@jasonnix As @DustinB already explained, Vates is the company behind XCP-ng and Xen Orchestra (XO). XCP-ng Center was (and still is) a community driven project not related to Vates. Search about the pro's and con's in the forum, there are a lot of good arguments. But for commercial customers, XOA is the way to go (and for most homelab user probably as well)
Last time I looked, XenCenter is now closed source and even behind a paywall (not sure about that), while Xen Orchestra is fully open source with all functionality in the from source version.
Since this is getting off-topic: did the communities feedback on your initial question help you to move forward? All good for your panel on Xen?

The official product to manage XCP-NG is Xen-Orchestra (XO) and XOlite.If you want you could contribute to the XCP-ng Center, the repository is still alive and can be found here: https://github.com/xcp-ng/xenadmin

@jasonnix please do more research before posting and telling things that are untrue. This behavior is not encouraged here.

@gskger, yes. I need to see if Ruby can easily do what I want.
