Hi, Community!

Please meet  a new Developer Community UI release with new features and some bugfixes.

With this release we changed a color scheme to meet corporate colors more. 

We introduced browser notifications not to miss new posts on Developer Community. They would pop up only if you turn them on and only if you don't see the Community at the moment. 

Also we introduced the special inverse color for accepted answers. Like here:

Dear question authors! Please mark answers as accepted to make the world better (of course if there is an answer, you can accept).

We also fixed a few bugs.

Have you ever thought about leveraging IIS (Internet Information Services for Windows) to improve performance and security for your Caché web applications?  
Are you worried about the complexity of properly setting up IIS?

See the webinar Configuring a Web Server presented by @Kyle Baxter,  InterSystems Senior Support Specialist. Learn how to install IIS, set up it up to work with the CSP Gateway, and configure the CSP Gateway to talk to Caché.

If you have not subscribed to our Developer Community YouTube Channel yet, let's get started right now.  

Enjoy!

Hi, Community!

You know that your productions need to be monitored. But what should you be monitoring, and how?

Let me invite you to join Michael Brady, Technical Trainer with InterSystems Learning Services, to learn about message volume monitoring tools, what really happens when you purge a message and how you can monitor your disk space from afar.

This webinar is valuable for anyone managing Ensemble or HealthShare productions.

It will take place on Thursday, May 4, 2017 10:30 am Eastern Daylight Time (New York, GMT-04:00) 

Hi!

If you see this page you are in the InterSystems Developer Community!

You are very welcome!

This is the place where you can read about and discuss InterSystems products and technologies: InterSystems IRIS, Caché, Ensemble, HealthShare, DeepSee, and iKnow. 

What type of content can I find here?

We have three types of content on Developer Community(DC): articles, questions, announcements. And answers to questions. And videos.

The articles are about the best practices and experience with InterSystems technology and products. Both InterSystems employees and community members post articles.

Hi, Community!

With the recent release on Developer Community we have introduced member mentioning.

Now if you want to ping a member with email notification, just place in the post (or comment) following:

@name.surname

Once it is published, a member would get the email notification that he was mentioned in particular post/comment.

So, that's how I'm mentioning myself here: @evgeny.shvarov.

Have a great weekend!

Hi, Community!

This post is an invitation for you to use the voting system in Developer Community.

Hi!

Sometimes when I have Zen page in a browser (e.g. Management Portal page) and when my Internet connection interrupts, I see the alert window on the page, something like this screenshot:

​

Is there any setting for the CSP web app to prevent this alerts from popping up?

Hi!

Sometimes I need to filter the widget on a dashboard from a different cube. And I face the following problem:

Widget A refers to a query from Cube A and I want to filter Widget B from Widget B.

Widget's B pivot refers to Cube B, and which has different dimensions for the same data.

E.g. cube A has the dimension Author and the Cube B has the dimension Member for the same data. So  there is no way to filter such a widget B from the widget A.

Hi, Community!

How can I manage to show in MDX query months where every month shows the value of the last month?

Say, in HoleFoods the query:

SELECT NON EMPTY [Measures].[Amount Sold] ON 0,NON EMPTY [DateOfSale].[Actual].[MonthSold].Members ON 1 FROM [HOLEFOODS]

will show me the sum of revenue per month.

This query:

SELECT NON EMPTY [Measures].[Amount Sold].MAX ON 0,NON EMPTY [DateOfSale].[Actual].[MonthSold].Members ON 1 FROM [HOLEFOODS]

will show the Max revenue in a day for the given month.

But what MDX will show the months with the revenue for the last day in a month?

I'm moving *D globals from DatabaseA to DatabalseB.

After importing globals I need to rebuild indices for all the imported persistent classes.

Colleagues, maybe you know one command which does it for all the classes in Namespace?

Hi, Community!

Is there an option to get an archived file of globals in one command. Say for:

Do $System.OBJ.Export("Class1*D.GBL,Class2*D.GBL","data_gbl.xml")

get something like:

Do $System.OBJ.Export("Data*D.GBL","data_gbl.gz","gzip")

And also to have the convenient one click way to  import it to the namespace via terminal or Control Panel?

If anyone already has this module, share please?

It would be very convenient for import/export/continuous integration purposes cause globals can be really heavy.

Hi, Community!

There are plenty of questions on Developer Community every day, which is great!

And which is even better - there are plenty of answers! 

A few months ago we introduced a nice feature - 'accepted answer'.

'Accepted answer' is a checkbox on the left of every other answer you see in a question post. So it let's op to mark the particular answer as accepted one. If you do that, this question disappears from unanswered filter.

And, we introduced a special challenge of "Accepted answer" in Global Masters which gives 150 points for every answer which is marked as accepted.

Hi, Community!

Here are some news on Developer Community enhancements.

In March we fixed a lot of bugs and rearranged the notification system, so I hope you'll be happy with it now.

Enhanced content of the notification

With this new release in every email notification you'll see the reason, why did you get this particular notification and the option to unsubscribe of this types of notifications.

The notification will indicate whether you are subscribed to everything, or to particular group/tag, post or you got the message because you are following some member.

Hi, Community!

Would you please share your best practices for utilising 3rd party modules (say community solutions, frameworks, development tools/utils).

There are two approaches which I like:

1. New namespace for every new module

So, if you install something you install it in special separate namespace/database. MDX2JSON/DeepSeeWeb case.

If the package is intended to be used in other namespaces, map the packages to %All and have it available in all the namespaces in this Caché/Ensemble.

And there is one more benefit: it is easy to uninstall the module, just delete the namespace/database.

2.

Hi, Community!

Let me share the news about  InterSystems Technology Student Contest we just have launched!

Hi, Community!

I hope you know the option to use DeepSee analytics portal for Developer Community stats. You can find it in Community-Analytics menu.

Let me introduce the beta of new analytical dashboard 'Articles' Views', which is available in Authors folder.

It consists of two dashboards, first shows the running total of the views for the articles (to see the impressive growing curve).

The second shows the daily additions in unique views (to analyze the dates of spikes).

Use the filters of Author, Article name, Publishing year and year timescale of analysis.

E.g.

Hi Community!

We want to invite you to join the InterSystems Gamification Platform called Global Masters Advocate Hub!

The Global Masters Advocacy Hub is our customer engagement platform where you will be invited to have some fun completing entertaining challenges, earning badges for the contribution to Developer Community, communicating with other advocates, and accumulating points which you can redeem for a variety of rewards and special honors.

Hi!

There is a 'New_window' control in DeepSee Widget which opens the page in a new tab in a browser with a given URL.

With the help of this control you can open another dashboard and supply some parameters in SETTINGS clause.

Consider  I can setup in Dash1 the URL like: 

_DeepSee.UserPortal.DashboardViewer.zen?DASHBOARD=Postings.dashboard&SETTINGS=TARGET:W1;FILTER: [Author].[H1].[Author].%26[$$$VALUELIST]

to filter the widget W1 in Postings dashboard with filter [Author].[H1].[Author].%26[$$$VALUELIST], where $$$VALUELIST is some value from the listing in a widget in Dash1.

Hi!

Recently GitHub introduced topics for the projects.

So you can change your InterSystems related projects introducing the  topics to let it be categorized, more visible and searchable. Here is the list of good examples for your projects (some of them are clickable already):

intersystems, intersystems-cache, intersystems-ensemble, intersystems-healthshare, healthshare, intersystems-iknow, iknow, intersystems-deepsee, deepsee, cache-objectscript, csp, intersystems-zen, zen.

If you have any good ideas for topics or already using something, please introduce it here in the comments?

Hi!

Consider I have a class Package.Data with Property UniqueStringValue as %String.

I introduced the Index for this property:

 Index ValueIndex on UniqueStringValue [Unique];

It works well.  But if I try to check if there is an object with the certain value in code like this:

if ##class(Package.Data).ValueIndexExists(value)  

this expression fails, if value="value", even if there is an instance with instance.UniqueStingValue="Value"

How can I set the index to prevent saving case sensitive values in this class?

Hi, Community!

Consider I have ResourceA which is used by role RoleA in dev environment and want to deploy it with the solution on a target system.

Would you please share the best practices to make it?

Thank you in advance!

Hi, Community!

We have a new release here!

What has been introduced:

1. Better notifications

With this release I hope you will turn on back the email notifications because every new notification today in the beginning of itself will tell first, why did you get it describing the exact reason you got this particular notification.  And if you don't want this type of notification to be delivered anymore click unsubscribe link in the notification and it will lead to the settings of this very type to alter.

Also, I can indeed recommend digest mode (Use Subscriptions/Overview to turn it on).

Hi!

How can I show a number of rows in a given DeepSee pivot?

Hi!

There are DeepSee dashboards,  which make sense only when filtered.

Usually, they are used as Drill Target or New_window control with SETTINGS=Widget;FILTER=filtervalue.

Is there a way to hide such dashboard from the Catalog or/and request the filter value once it is opened by User?

Hi Community!

We are launching the new channel of InterSystems Technology content for you. Please welcome InterSystems Developers YouTube Channel!

What the content you will find there:

• Community Tools and Solutions for Developers - screencasts, promoting different 3rd party solutions for developers.
• Webinars - will contain webinars content made by InterSystems engineers.
• InterSystems Events - live broadcastings and reviews from different InterSystems events for developers.
• video.intersystems.com playlist - featured technical videos from http://video.intersystems.com library.
