1. maj 2019 / admin / Kommentarer lukket

This is just a follow up on this post: https://azure.microsoft.com/en-us/blog/simplifying-security-for-serverless-and-web-apps-with-azure-functions-and-app-service/ for a bit more clarification on the roles and policies required in KeyVault to make this work.

The enable an Azure Function to access secrets in KeyVault you have to do the following:

Create a system assigned managed identity to the Function. Just go to Platform Features in your Function and select Identity and enable the System assigned identity – remember to click save!
Giving the role “Managed Application Reader” to the managed identity of the Function.
1. Go to KeyVault and click on “Access control (IAM) in the menu and click on “Role assignments”.
2. If you want to see existing App/Functions that have assignments select “App Services or Function Apps” from the Type dropdown menu.
3. Click on Add and select the “Managed Applications Reader” from the Role drop down menu.
4. Type in the name of your Function and select it from the menu – make sure you select the actual identity of the Function – see the icon in the screendump below.
5. Click on save.
Assigning at least the “Get Secret” policy to the service principle of the managed identity.
1. Click on “Access policies” in the KeyVault menu
2. Click on Add and click on the “Select principal” fly out menu and type in the name of your Function
3. This time it’s the service principal we want to select – click on it and click on select
4. From the “Secret permissions” drop down menu select at least the “Get” permission.
5. Click on OK.

You’re done and you should now be able to get secrets from your KeyVault in your application settings in your Function.

8 Principles of Open Government Data

17. marts 2016 / admin / Kommentarer lukket

Open Government Data Principles

Government data shall be considered open if it is made public in a way that complies with the principles below:

1. Complete: All public data is made available. Public data is data that is not subject to valid privacy, security or privilege limitations.

2. Primary: Data is as collected at the source, with the highest possible level of granularity, not in aggregate or modified forms.

3. Timely: Data is made available as quickly as necessary to preserve the value of the data.

4. Accessible: Data is available to the widest range of users for the widest range of purposes.

5. Machine processable: Data is reasonably structured to allow automated processing.

6. Non-discriminatory: Data is available to anyone, with no requirement of registration.

7. Non-proprietary: Data is available in a format over which no entity has exclusive control.

8. License-free: Data is not subject to any copyright, patent, trademark or trade secret regulation. Reasonable privacy, security and privilege restrictions may be allowed.

Compliance must be reviewable.

Definitions

1.	“public” means:The Open Government Data principles do not address what data should be public and open. Privacy, security, and other concerns may legally (and rightly) prevent data sets from being shared with the public. Rather, these principles specify the conditions public data should meet to be considered “open.”
2.	“data” means:Electronically stored information or recordings. Examples include documents, databases of contracts, transcripts of hearings, and audio/visual recordings of events. While non-electronic information resources, such as physical artifacts, are not subject to the Open Government Data principles, it is always encouraged that such resources be made available electronically to the extent feasible.
3.	“reviewable” means:A contact person must be designated to respond to people trying to use the data. A contact person must be designated to respond to complaints about violations of the principles. An administrative or judicial court must have the jurisdiction to review whether the agency has applied these principles appropriately.

Common Date Time formulas for Sharepoint – Calculated Fields

18. marts 2014 / admin / Kommentarer lukket

From http://abstractspaces.wordpress.com/2009/05/02/common-date-time-formulas-for-sharepoint-calculated-fields/ for future reference:

Get Week of the year
=DATE(YEAR([Start Time]),MONTH([Start Time]),DAY([Start Time]))+0.5-WEEKDAY(DATE(YEAR([Start Time]),MONTH([Start Time]),DAY([Start Time])),2)+1
First day of the week for a given date:
=[Start Date]-WEEKDAY([Start Date])+1
Last day of the week for a given date:
=[End Date]+7-WEEKDAY([End Date])
First day of the month for a given date:
=DATEVALUE(“1/”&MONTH([Start Date])&”/”&YEAR([Start Date]))
Last day of the month for a given year (does not handle Feb 29). Result is in date format:
=DATEVALUE (CHOOSE(MONTH([End Date]),31,28,31,30,31,30,31,31,30,31,30,31) &”/” & MONTH([End Date])&”/”&YEAR([End Date]))
Day Name of the week : e.g Monday, Mon
=TEXT(WEEKDAY([Start Date]), “dddd”)
=TEXT(WEEKDAY([Start Date]), “ddd”)

The name of the month for a given date – numbered for sorting – e.g. 01. January:
=CHOOSE(MONTH([Date Created]),”01. January”, “02. February”, “03. March”, “04. April”, “05. May” , “06. June” , “07. July” , “08. August” , “09. September” , “10. October” , “11. November” , “12. December”)
Get Hours difference between two Date-Time :
=IF(NOT(ISBLANK([End Time])),([End Time]-[Start Time])*24,0)
Date Difference in days – Hours – Min format : e.g 4days 5hours 10min :
=YEAR(Today)-YEAR(Created)-IF(OR(MONTH(Today)<MONTH(Created),AND(MONTH(Today)=MONTH(Created),
DAY(Today)<DAY(Created))),1,0)&” years, “&MONTH(Today)-MONTH(Created)+IF(AND(MONTH(Today)
< =MONTH(Created),DAY(Today)<DAY(Created)),11,IF(AND(MONTH(Today)<MONTH(Created),DAY(Today)
> =DAY(Created)),12,IF(AND(MONTH(Today)>MONTH(Created),DAY(Today)<DAY(Created)),-1)))&” months,
“&Today-DATE(YEAR(Today),MONTH(Today)-IF(DAY(Today)<DAY(Created),1,0),DAY(Created))&” days”

Suggestions for SharePoint Conference 201x

19. november 2012 / admin / Kommentarer lukket

Just got back from an amazing week at the SharePoint Conference 2012 in Las Vegas. Great sessions, great networking (with the people in mean), great social events and not so great swag.

On the way out someone asked me what could be done to improve the experience at the next conference.

This year two things comes to mind:

Presentation skills and wired networking for presentations
Use SharePoint to organize and deliver the conference

Presentation skills

Presentation skills are vital to deliver any message and especially when doing technical talks slides and demos have to be dead on. The presenter has to engage the audience and not just deliver a recital from the yellow pages. If the presenter is exited and energetic then the message usually comes across much clearer.

Techniques like knowing how to use magnifier and larger fonts in Visual Studio is just a prerequisite. Unfortunately I experienced several presenters that didn’t use these basic tools and settings which made it impossible to see what was presented on the screens.

Overall I would have to say that the level of presentation skill and talent was lower this year than before. So this is a must for the next conference.

This is a no-brainer for anyone delivering presentations anywhere. I never never go to a customer and rely on wireless connectivity. Wifi and 3/4G hotspots are just to flakey. Next time please make sure that presentations use wired networking so that demos doesn’t fail because of network congestion.

Use SharePoint to organize and deliver the conference

Not using SharePoint to deliver the conference and engage the attendees is simply a mind blower for me. How cool would it be to use SharePoint to collaborate on the sessions – see and try the demos for your self in real time. To get instant access to the code and slides. To interact with the other attendees using social and other features. Use Yammer to setup a private network for the conference – I could have done that in 2 minutes.

So next time – use SharePoint to organize and deliver the conference.

Dansk selvbetjening skyder forbi de unge

2. oktober 2012 / admin / Kommentarer lukket

I følge Dansk IT og den seneste IT i Praksis 2012 skyder de danske selvbetjeningsløsninger forbi de unge fordi de er mere vant til at bruge løsninger som Facebook, Twitter osv.

Jeg tror årsagen ligger et helt andet sted.

Selvbetjening hos Skat

Tillad mig at komme med et lille eksempel fra det virkelige liv. Hvis jeg f.eks. gerne vil kontakt med Skat skal jeg på forsiden hos Skat først vælge hvem jeg overhovedet er og hvordan jeg vil logge på?!

Hvis jeg så ved at jeg vil bruge NemId, ja så er det frem med det elskede lille papkort og igennem den velkendte logon dialog (hvor selvom jeg allerede har valgt at jeg vil bruge NemId alligevel kan vælge andre muligheder?).

Efter logon møder jeg så nedenstående oversigt fra Skat der kan tage pusten fra enhver. Her kunne Skat godt lære noget af kommunerne der efterhånden har opdaget det med vise information der passer på min siutation. Når jeg nu er logget på med NemId, hvorfor så ikke starte med at vise information der er relevant for mig lige nu udfra skats oplysninger om mig og datoen taget i betragtning.

Jeg tror ikke at man skal være en særlig stor ekspert indenfor UX før man kan sige at oplevelsen godt kan gøres bedre – både for unge, ældre og gamle.

Selvbetjening hos Danske Bank

Hvis jeg nu vil i kontakt med min bank (i dette tilfælde Danske Bank) i stedet for Skat, så tager jeg min SmartPhone op af lommen og starter Danske Mobil App’en.
Her mødes jeg med følgende skærmbilled:

Hvis jeg trykker på den grønne knap for at logge ind.

Kan jeg nøjes med at indtaste et brugerid og en pinkode som jeg har aftalt med banken. Jeg behøver slet ikke at have mit lille papkort med – jeg skal bare have min SmartPhone, og hvis jeg er mellem 18 og 40 år gammel så er der mere end 99% sandsynlighed at jeg har min telefon og ikke mit papkort i lommen.
Når jeg er logget ind kan jeg med fingeren navigere og vælge hvilken funktion jeg vil bruge.

Nu vælger jeg at se kurslister for danske kroner mod dollars.

Jeg kan også foretage se saldo på mine konti, betale regninger og alle de andre ting som man forventer af en netbank.

Ambitionsniveauet skal op

Forskellen på Danske Mobil og Skats selvbetjeningsløsninger kan ikke være større. Skat virker kun på en computer og kræver NemId, Danske Mobil virker på Apple og Android og kræver ikke NemId. Hvis Danske Bank har vurderet, at det ikke er nødvendigt med NemId for at gøre deres mobile netbank sikker, hvorfor kan Skat så ikke også? Skat har brugt millioner af skattekroner på det ene SOA projekt efter det andet, så man skulle da tro at der var en webservice eller to der kunne bruges som bagende til en Skat mobilselvbetjening. Det er lige før jeg vil tilbyde at implementere en løsning til Skat gratis hvis jeg så må få en krone bagefter for hver borger der bruger løsningen.
Jeg tror slet ikke at problemet med de unges forbrug af selvbetjeningsløsninger har noget at gøre med Facebook, Twitter eller sociale medier i det hele taget – jeg tror mere at de offentlige selvbetjeningsløsninger har for dårlig UX og så er de ikke til stede der hvor de unge er online, nemlig på telefon og ikke på computer. I Danmark er udbredelsen af SmartPhones ligeså høj som i Sydkorea og alligevel kan man stadig ikke betale med sin telefon (pånær Roskilde Festival) eller komme i kontakt med det offentlige med mindre man er på jagt efter et toilet.
Det handler om at hæve ambitionsniveauet i stedet for at lave løsninger der er kryblet på forhånd for at leve op til WCAG L2 og alle mulige andre tilgængelighedskrav der (retteligt) skal gøre det muligt for personer med diverse perceptionshandicap at bruge løsningerne i stedet for at bruge pengene på de 99% (mit bud, fra hoften) der rent faktisk ikke har nogen handicap.
