Weka Save Model Menu is Always Disabled - weka

I am trying out Weka and I've found that, so far, every option I've tried (all types of trees) for classification did not allow me to save the model because that option was grayed out and disabled. How do I save a model?

In WEKA explorer make sure "Output Model" is enabled from "More options". This setting should change to "Store Output Model" to make sense to be fair.

I replicated the results on my ArchLinux and mac OSx on Weka 3.8 and I did not have the problem you mentioned. Are you on Windows? If so, I recommend reinstalling the latest stable version.

Bugs Weka 3.8.6

After loading a dataset diabetes.arff and then choosing a classifier such as J48, I can start one test and after that the button "start" becomes disabled. Even clicking on stop it continues disabled. I changed the classifier to ZeroR and then the button became enabled again, but it does not work.I clicked several times and nothing. I also reinstalled Weka and tried other datasets, but every time the same problem.
I recorded a video to show this bug on https://1drv.ms/v/s!ApZk5TJm2dA3odp28KVQSssv34Lu4Q?e=uyrTD7
As an alternative, you could try the Weka Investigator, a more powerful tool than the Weka Explorer. The Investigator is part of the ADAMS framework. For your purposes, you can download the adams-ml-app snapshot from the snapshot download page
Have a look at the video of my talk from the Weka User Conference 2021, for an introduction to the tool.

Sitecore 8.1 experience editor is very slow

We upgraded the sitecore from 7.2 to 8.1. Since the upgrade the content authors are complaining that the experience editor performance is much slower than previous version. It takes long time to load and also editing experience is very slow as well.
For now I've reverted back to SHEER UI version of experience editor by updating experienceeditor.config.
I read this blog post below but option 1 and 2 states "be aware that there are significant consequences...".
http://kamsar.net/index.php/2015/02/sitecore-8-experience-editor-performance-optimization/
Has any one experience this issue? And have any recommendation for the fix?
Thanks.
Reverting to SheerUI is probably an option you could consider... we know it works faster that the SPEAK UI, so it's a quick win to help out your content editors at the moment.
However Sitecore is moving towards SPEAK, and so I'm not sure how long the SheerUI interface will still keep up with the new features of the Experience Editor.
In addition to the pre-compilation of Views, you COULD attempt Kam's optimization, but as he mentioned, there could be significant issues that come about because of it.
I would also have a look into some other possibilities for speeding it up, like:-
Use the application cache to increase the performance of loading the
Experience Editor ribbon. - (https://doc.sitecore.net/Sitecore%20Experience%20Platform/The%20editing%20tools/Improve%20the%20performance%20of%20the%20Experience%20Editor%20ribbon)
Using ContentSearch instead of Fast Query for the 'My Items' count - (http://mikael.com/2015/12/speading-up-the-sitecore-experience-editor/), or even turning off the count altogether (http://sitecoreblog.alexshyba.com/hidden_gem_of_sitecore_page_editor/). UPDATE: Sitecore now has a Support DLL for this. (https://kb.sitecore.net/en/Articles/2015/12/04/14/31/549951.aspx)
Customize or even disable the SuggestedTestsCountRequest. - (http://blog.horizontalintegration.com/2015/07/05/sitecore8-experience-editor-slow/)

WinCE 6.0: Customizing Control Panel (cplmain)

i work on a Windows CE 6.0 Image and added a Audio driver to my Solution (my solution is based on a image without audio). Sound works fine but i dont know how i can add the standard Windows CE 6.0 Sound Settings dialog to the control panel.
MSDN says the following:
"The Windows CE Control Panel allows users to set a variety of system-wide properties, such as mouse sensitivity, network setup, and the desktop color scheme. You can select specific functionality to include in your Control Panel by specifying them in your Cesysgen.bat file."
Can anyone explain how this works exactly via Cesysgen.bat? In my project i cant find any entry for cplmain in my Cesysgen.bat.
Could it be that those standard Applets are integrated into the control panel automatically? (maybe with "getProcAddress()" when a specific driver is loaded?) - This idea comes from "cplmain.def", there is written:
EXPORTS
CPlApplet
; These functions are exported for componentization
; We use GetProcAddress on ourselves to dynamically discover
; what components we have
I found a quite good explanation from Andrew Pearson here:
http://www.itlisting.org/4-windows-ce-embedded/a57eef4103191b7a.aspx
but i tried a few different things an nothing worked! So this confuses me even more. The only statement there i really understand now is:
The control panel, unfortunately, is about the single most confusing thing
to build in the whole tree.
Yes it is! Would be nice if anyone had an idea.
Kind regards,
Martin
I've created custom control panel applets before, and to be honest, trying to modify the existing applet is about the worst thing you can try. Generally what I do is just create a whole new applet, which is really just a DLL renamed to have a .cpl extension and that exports the CPlApplet entry point.
There's an example in MSDN that shows the expected values the OS will pass in to get your icon, tell you to start and those types of things.
Basically just build your own applet as a completely separate project, then include it in the MODULES section of your BIB file. Don't even mess with the existing train wreck of control panel code.

ShowEditor and Rich Text Field is not displaying in sitecore 7.1 application

We have migrated an application from sitecore 6.2 to sitecore 7.1.
We are facing an issue related to Rich Text Field which is not showing up when I open a content item. The Show Editor is also not popping up the Rich Text Editor for editing.
When I am facing this kind of issues after upgrading I tend to put tickets # support.sitecore.net and dig some deeper into it myself. What I normally do is get a clean web.config + complete fresh bin folder of the Sitecore version I've upgraded to. Also I make sure that I grab the /sitecore folder with it.
Then I will compare the fresh bin with the solution bin and replace any assemblies that are not the same. From there I will also do a folder compare (using beyond compare or any other good compare tool) to make sure I got all the necessary files from there. Also I make sure that I look for any posts on the Sitecore forum containing the same problems. Don't forget to view your logs, as they will sometime help you find your problem quicker.

How to get consolidated report of project mile stones for all projects in Redmine

We are Redmine as a Project management tool. It has been working great and we are happy with it. We now have a new requirement now. Our management wants to see a report showing each project's delivery date, manager, start date, total issues, open issues, closed issues. I searched at several places for quite some time and did not get a solution. I appreciate if someone can offer help.
This is, for me personally, the single thing JIRA is better at :)
Anyway, that being said, you can get a summary of all open versions on your "my page", eh, page, by using this plugin:
https://github.com/bradbeattie/redmine-my-widgets-plugin
And you can also add custom queries to "my page".
You can get much of what you want in the issue report. Click the Summary button in the sidebar of the issues page in each project. Example
Create one generic top level project. Calendar, gantt charts, issues, etc, for the top level project will show everything for every project that's nested underneath.
If you are properly adding roadmaps/milestones to all the projects, you can use My Roadmaps plugin to get a consolidated visibility:
http://www.redmine.org/plugins/my_roadmaps
It works fine with 1.2 and 1.4 versions.
