• Why are embedded device apps still written in C/C++? Why not Java programming language?

  - by hinkmond

  At the recent Black Hat 2014 conference in Sin City, the Black Hatters were focusing on Embedded Devices and IoT. You know? Make your networked-toaster burn your bread 10,000 miles away, over the Web for grins and giggles. Well, apparently the Black Hatters say it can be done pretty easily these days, which is scary. See: Securing Embedded Devices & IoT Here's a quote: All these devices are still written in C and C++. The challenges associated with developing securely in these languages have been fought for nearly two decades. "You often hear people say, 'Well, why don't we just get rid of the C and C++ language if it's so problematic. Why don't we just write everything in C# or Java, or something that is a little safer to develop in?'," DeMott says. Gah! Why are all these IoT devices still using C/C++? Of course they should be using Java SE Embedded technology! It's a natural fit to use for better security on embedded devices. Or, I guess, developers really don't mind if their networked-toasters do char their breakfast. If it can be burned, it will be... That's what I say. Unless they use Java. Hinkmond

• GCC: assembly listing for IA64 without an Itanium machine

  - by KD04

  I need to try the following thing: I would like to compile some simple C code samples and see the assembly listing generated by GCC for IA64 architecture, i.e. I just want to run GCC with the -S switch and see the resultant .s file. I don't have an Itanium machine, so in order to do it myself I'll probably need a cross-compiling version of GCC built for x86 RedHat. I'm not interested in full cross-compilation, meaning that I don't need to generate the binaries at all. The easiest way, of course, would be to find an Itanium machine with with GCC and just try it there. Unfortunately, I don't seem to have access to any. Another option is to build a cross-compiling version GCC on my RedHat, but apparently that's quite an endeavor for someone who hasn't done it before (I assume that the fact that I only need .s output doesn't make it simpler). What other options are there, if any? Maybe there's some sort of a web front to an Itanium GCC compiler on the Net (something like Comeau Online or ideone.com, but with .s output)? Anything else? I would appreciate any help.

• Input/Output console window in XNA

  - by Will Bagley

  I am currently making a simple game in XNA but am at a point where testing various aspect gets a bit tricky, especially when you have to wait till you have 1000 score to see if your animation is playing correctly etc. Of course i could just edit the starting variable in the code before I launched but I have recently been interested in trying to implement a console style window which can print out values and take input to alter public variables during run-time. I am aware that VS has the immediate window which achieves a similar thing but i would prefer mine is an actual part of the game with the intention that the user may have limited access to it in the future. Some of the key things i have yet to find an answer to after looking around for a while are: how i would support free text entry how i would access variables during runtime how i would edit these variable I have also read about using a property grid from windows form aps (and partially reflection) which looked like it could simplify a lot of things but i am not sure how I would get that running inside my XNA game window or how i would get it to not look out of place (as the visual aspect of is seems to be aimed just for development time viewing). All in all I'm quite open to any suggestions on how to approach this task as currently I'm not sure where to start. Thanks in advance.

• Oracle VM Virtualbox 4.0 extension packs

  - by wim.coekaerts

  Some people have asked what this new extension pack is in Oracle VM Virtualbox 4.0 and how it's different from 3.2 and earlier releases. The extension pack is a restructuring of how Oracle VM VirtualBox is installed. Please take a look at http://virtualbox.org and read up on what the product install looked like prior to 4.0, you'll see the following : There were 2 versions to download : - Oracle VM VirtualBox (open source edition) OSE - download of the source tarball with a GPL license + compile needed to run. - Oracle VM VirtualBox PUEL (personal use/eval license) - download of an installable binary with a number of additional non-gpl license drivers, usb2, sata, pxe boot for e1000, vrdp server etc., all built in to the install. This contained the OSE edition + additional drivers with the installer. Customers could purchase an enterprise software license for the latter version. To make it easier to build and release additional drivers, they have been separated out and are now installed through an "extension pack" starting with Oracle VirtualBox version 4. This extension pack is still licensed the same way as in every prior version, via a PUEL license or with the ability to purchase a commercial license. It is now also possible for other companies or users that want to add extensions to do so by creating a similar extension pack -- and there's no need to do a new release of the entire product to do so. So it's a more flexible structure for installing VirtualBox and drivers and allows for more modular additions. The source code of Oracle VM Virtualbox is, of course, still available just like in 3.x, for 4.0. Like 3.x, not for the additional drivers which are now in the extension pack.

• What functionality should a (basic) mock framework have?

  - by user1175327

  If i would start on writing a simple Mock framework, then what are the things that a basic mock framework MUST have? Obviously mocking any object, but what about assertions and perhaps other things? When I think of how I would write my own mock framework then I realise how much I really know (or don't know) and what I would trip up on. So this is more for educational purposes. Of course I did research and this is what i've come up with that a minimal mocking framework should be able to do. Now my question in this whole thing is, am I missing some important details in my ideas? Mocking Mocking a class: Should be able to mock any class. The Mock should preserve the properties and their original values as they were set in the original class. All method implementations are empty. Calls to methods of Mock: The Mock framework must be able to define what a mocked method must return. IE: $MockObj->CallTo('SomeMethod')->Returns('some value'); Assertions To my understanding mocking frameworks also have a set of assertions. These are the ones I think are most important (taken from SimpleTest). expect($method, $args) Arguments must match if called expectAt($timing, $method, $args) Arguments must match when called on the $timing'th time expectCallCount($method, $count) The method must be called exactly this many times expectMaximumCallCount($method, $count) Call this method no more than $count times expectMinimumCallCount($method, $count) Must be called at least $count times expectNever($method) Must never be called expectOnce($method, $args) Must be called once and with the expected arguments if supplied expectAtLeastOnce($method, $args) Must be called at least once, and always with any expected arguments And that's basically, as far as I understand, what a mock framework should be able to do. But is this really everything? Because it currently doesn't seem like a big deal to build something like this. But that's also the reason why I have the feeling that i'm missing some important details about such a framework. So is my understanding right about a mock framework? Or am i missing alot of details?

• Windows Phone 7 event

  - by Dennis Vroegop

  This might not be of interest to anyone living outside of the Netherlands, but I still wanted to share this. On march 10th the dutch .net usergroup dotNed (of which I am chairman) organizes a LAN party together with the company Sevensteps. Sevensteps is a big player in the Surface area: they are one of the few companies whose applications are part of the standard tools you get when you buy a Surface unit. They were also present at the CES in Las Vegas earlier this year to introduce the SUR40, as mentioned in my previous post. But they do not only develop software for the Surface, they also do a lot of interesting things on other platforms. One of these is Windows Phone 7, or WP7 in short. Sevensteps and dotNed have joined forces to organize a free full day event where we will develop a WP7 application. The people attending will be developers (experienced and not so experienced on WP7), designers and all other sorts of people you’d expect in a project team. The day will start around 9.00 am and will end when the app is finished. We will form teams of both experienced and not experienced developers so that we can learn from each other. Each team will have their own task to perform, and in the end all parts will be assembled to form a killer WP7 app. As with everything that dotNed does this event is free for everyone. Microsoft will pay for dinner, Sevensteps will provide the room, lunch and ideas (and their expertise of course) and the rest is up to us! So if you are in The Netherlands that date, and you feel like hanging out with other WP7 or wannabe WP7 developers, join us! For more information (in Dutch) see http://www.dotned.nl Tags van Technorati: wp7,dotned

• The Bing Sting - an alternative opinion

  - by Charles Young

  I know I'm a bit of an MS fanboy at times, but please, am I missing something here? Microsoft, with permission of users, exploits clickstream data gathered by observing user behaviour. One use for this data is to improve Bing queries. Google equips twenty of its engineers with laptops and installs the widgets required to provide Microsoft with clickstream data. It then gets their engineers to repeatedly (I assume) type in 'synthetic' queries which bring back 'doctored' hits. It asks its engineers to then click these results (think about this!). So, the behaviour of the engineers is observed and the resulting clickstream data goes off to Microsoft. It is processed and 'improves' Bing results accordingly.   What exactly did Microsoft do wrong here?   Google's so-called 'Bing sting' is clearly a very effective attack from a propaganda perspective, but is poor practice from a company that claims to do no evil. Generating and sending clickstream data deliberately so that you can then subsequently claim that your competitor 'copied' that data from you is neither fair nor reasonable, and suggests to me a degree of desperation in the face of real competition.   Monopolies are undesirable, whether they are Microsoft monopolies or Google monopolies.    Personally, I'm glad Microsoft has technology in place to observe user behaviour (with permission, of course) and improve their search results using such data. I can only assume Google doesn't implement similar capabilities. Sounds to me as if, at least in this respect, Microsoft may offer the better technology.

• How to implement a no-login authentication system

  - by mrwooster

  I am looking to build a very loose authentication system that can track a user and link submitted data/comments to a specific user. The submissions are essentially anonymous, but a user may want to edit his submission/comment at a later date. I want the experience to be as smooth as possible so do not want to ask users to sign up for an account and then login each time. There is no point as their submissions are not in their name and to another user browsing the site, there is no way of linking a submission to a specific user (think anonymous comments on a blog post or pastie). However, the user should have the ability to edit (at least in the short term) the content they have posted. The way I imagine doing this would be to place a unique identifier in a cookie on the users machine. This would enable me to link a submission to a user, and while that cookie remained on the users machine, I would allow them to edit their content. Of course, if the cookie is lost, or the user accesses the site from a different browser, then they would not be able to edit their content, but this is not really an issue, they can always resubmit a new piece of content. Is there a better way of doing this? How can I implement this so that the user can edit their data for the longest possible amount of time.

• Have You Checked Our BI Publisher Channel at Youtube ?

  - by kanichiro.nishida

  These days, more and more people watching video online rather than reading. Steve Jobs once said people don’t read anymore. Well, I love books and still read a lot either on books, magazine, iPad, MacbookPro, or whatever the medium shows me letters! But I have to admit, sometimes it’s much easier to understand especially something like How-To by just watching video clips than reading it. And this is why we started our BI Publisher Channel at Youtube last summer. Since then we have uploaded over 10 video clips so far and and now we’re gearing up to add more and more clips. Now, we’re in a middle of finishing up our work for the next 11G 1st patchset release, which should be coming soon and will have a lot of great new features that I can’t wait to talk to you guys about. And of course we’re preparing introduction and How-Top clips. So please subscribe the BI Publisher channel now if you haven’t done yet and stay tuned for the new clips! http://www.youtube.com/user/bipublisher Also, we’d love to hear your comments for each clip, so please don’t forget leaving your comments there after you watch!

• What's the best way to manage error logging for exceptions?

  - by Peter Boughton

  Introduction If an error occurs on a website or system, it is of course useful to log it, and show the user a polite message with a reference code for the error. And if you have lots of systems, you don't want this information dotted around - it is good to have a single centralised place for it. At the simplest level, all that's needed is an incrementing id and a serialized dump of the error details. (And possibly the "centralised place" being an email inbox.) At the other end of the spectrum is perhaps a fully normalised database that also allows you to press a button and see a graph of errors per day, or identifying what the most common type of error on system X is, whether server A has more database connection errors than server B, and so on. What I'm referring to here is logging code-level errors/exceptions by a remote system - not "human-based" issue tracking, such as done with Jira,Trac,etc. Questions I'm looking for thoughts from developers who have used this type of system, specifically with regards to: What are essential features you couldn't do without? What are good to have features that really save you time? What features might seem a good idea, but aren't actually that useful? For example, I'd say a "show duplicates" function that identifies multiple occurrence of an error (without worrying about 'unimportant' details that might differ) is pretty essential. A button to "create an issue in [Jira/etc] for this error" sounds like a good time-saver. Just to re-iterate, what I'm after is practical experiences from people that have used such systems, preferably backed-up with why a feature is awesome/terrible. (If you're going to theorise anyway, at the very least mark your answer as such.)

• Attributes of an Ethical Programmer?

  - by ahmed

  Software that we write has ramifications in the real world. If not, it wouldn't be very useful. Thus, it has the potential to sweep across the world faster than a deadly manmade virus or to affect society every bit as much as genetic manipulation. Maybe we can't see how right now, but in the future our code will have ever-greater potential for harm or good. Of course, there's the issue of hacking. That's clearly a crime. Or is it that clear? Isn't hacking acceptable for our government in the event of national security? What about for other governments? Cases of life-and-death emergency? Tracking down deadbeat parents? Screening the genetic profile of job candidates? Where is the line drawn? Who decides? Do programmers have responsibility for how their code is used? What if a programmer writes code to pry into confidential information or copy-protected material? Does he bear responsibility along with the person who used the program? What about a programmer who knowingly or unknowingly writes code to "fix the books?" Should he be liable?

• Architecture a for a central renderer rather than self-rendering

  - by The Communist Duck

  For the architectural side of rendering, there's two main ways: having each object render itself, and having a single renderer which renders everything. I'm currently aiming for the second idea, for the following reasons: The list can be sorted to only use shaders once. Else each object would have to bind the shader, because it's not sure if it's active. The objects could be sorted and grouped. Easier to swap APIs. With a few macro lines, it can be easy to swap between a DirectX renderer and an OpenGL renderer (not a reason for my project, but still a good point) Easier to manage rendering code Of course, if anyone has strong recommendations for the first method, I will listen to them. But I was wondering how make this work. First idea The renderer has a list of pointers to the renderable components of each entity, which register themselves on RenderCompoent creation. However, I'm worrying that this may end up as a lot of extra pointer weight. But I can sort the list of pointers every so often. Second idea The entire list of entities is passed to the renderer each render call. The renderer then sorts the list (each call, or maybe once?) and gets what it wants. That's a lot of passing and/or sorting, however. Other ideas ??? PROFIT Anyone got ideas? Thank you.

• Is realtime validation of username good or bad?

  - by iamserious

  I have a simple form for the user to sign up to my site; with email, username and password fields. We are now trying to implement an ajax validation so the user doesn't have to post the form to find out if the username is already taken. I can do this either on keyup event or on text blur event. My question is, which of these is really the best way to do? Keyup From the user POV, it would be good if the validation is done as and when they are typing, (on key up event) - of course, I am waiting for half a second to see if the user stops typing before firing off the request, and user can make any adjustments immediately. But this means I am sending way more requests than if I validated the username on Blur event. Blur The number of requests will be much lower when the validation is done on blur event, But this means the user has to actually go away from the textbox, look at the validation result, and if necessary go back to it to make any changes and repeat the whole process until he gets it right. I had a quick look at google, tumblr, twitter and no one actually does username validations on keyup events, (heck, tubmlr waits for the form to be posted) but I can swear I have seen keyup validations in a lot of places too. So, coming back to the question, will keyup validations be too many for server, is it an unnecessary overhead? or is it worth taking these hits to give user a better experience? ps: all my regex validations etc are already done on javascript and only when it passes all these other criteria does it send a request to server to check if a username already exists. (And the server is doing a select count(1) from user where username = '' - nothing substantial, but still enough to occupy some resource) pps: I'm on asp.net, MS SQL stack., if that matters.

• Ubuntu Slow - What architecture does the Windows Installer install?

  - by Benjamin Yep

  I feel absolutely limited by using Windows, and I need to switch to a Unix environment. I once installed Red Hat on my lappie (screen + external monitor setup; 4GB ram; x64; runs fast) and it worked fine, but I saw that the computer cluster that is the birthplace of my unix knowledge switched to Ubuntu, so naturally I follow. To the point. When I installed Ubuntu onto my machine via the Windows Installer, it ran quite slow. Opening Firefox takes about 8-9 seconds, it freezes up often, unable to handle its own background processes. I saw in a thread that, perhaps, it is running slow because the Windows Installer is installing an x64 version. Of course, my computer has had no performance issues in the past(except that time with the trojans but you know, know one is perfect ;) ) Anyways, I uninstalled Ubuntu, freeing up the max allocated memory it took up, and continue to be sad, trapped in my MS world with only a buggy Cygwin, any assistance is greatly appreciated! :) Thanks ~Ben

• SQL Rally Nordic & Amsterdam slides & demos

  - by Davide Mauri

  Last week I had the pleasure to speak at two GREAT conferences (as you can see from the wordcloud I’ve posted, here for Stockholm and here for Amsterdam. I used two different filtering techniques to produce the wordcloud, that’s why they look different. I’m playing a lot with R in these days…so I like to experiment different stuff). The workshop with my friend Thomas Kejser on “Data Warehouse Modeling – Making the Right Choices” and my sessions on “Automating DWH Patterns through Metadata” has been really appreciated by attendees, give the amount of good feedback I had on twitter and on some blog posts (Here and here). Of course many asked for slides & demos to download, so here you are! Automating DWH Patterns through Metadata – Stockholm http://sdrv.ms/1bcRAaW Automating DWH Patterns through Metadata – Amsterdam http://sdrv.ms/1cNDAex I’m still trying to understand if and how I can publicly post slides & demos of the workshop, so for that you have to wait a couple of days. I will post about it as soon as possible. Anyway, if you were in the workshop and would like to get the slide & demos ASAP, just send me an email, I’ll happily sent the protected link to my skydrive folder to you. Enjoy!

• Freescale One Box Unboxing (then installing Java SE Embedded technology)

  - by hinkmond

  So, I get a FedEx delivery the other day... "What cool device could be inside this FedEx Overnight Express Large Box?" I was wondering... Could it be a new Linux/ARM target device board, faster than a Raspberry Pi and better than a BeagleBone Black??? Why, yes! Yes, it was a Linux/ARM target device board, faster than anything around! It was a Freescale i.MX6 Sabre Smart Device Board (SDB)! Cool... Quad Core ARM Cortex A9 1GHz with 1GB of RAM. So, cool... I installed the Freescale One Box OpenWRT Linux image onto its SD card and booted it up into Linux. But, wait! One thing was missing... What was it? What could be missing? Why, it had no Java SE Embedded installed on it yet, of course! So, I went to the JDK 7u45 download link. Clicked on "Accept License Agreement", and clicked on "jdk-7u45-linux-arm-vfp-sflt.tar.gz", installed the bad boy, and all was good. Java SE Embedded 7u45 on a Freescale One Box. Nice... Hinkmond

• What is an effective way to convert a shared memory-mapped system to another data access model?

  - by Rob Jones

  I have a code base that is designed around shared memory. Each process that needs to access the memory maps it into its own address space. The data structures in the shared memory are directly accessed, that is, there is no API. For example: Assume the following: typedef struct { int x; int y; struct { int a; int b; } z; } myStruct; myStruct s; Then a process might access this structure as: myStruct *s = mapGlobalMem(); And use it as: int tmpX = s->x; The majority of the information in the global structure is configuration information that is set once and read many times. I would like to store this information in a database and develop an API to access the database. The problem is, these references are sprinkled throughout the code. I need a way to parse the code and identify global structure references that will need to be refactored. I've looked into using ANTLR to create a parser that will identify references to a small set of structures and enter them into a custom symbol table. I could then use this symbol table to identify which source files need to be refactored. It looks like a promising approach. What other approaches are there? Of course, I'm looking for a programmatic approach. There are far too many source files to examine each one visually. This is all ordinary ANSI C. Nothing else.

• CA For A Large Intranet

  - by Tim Post

  I'm managing what has become a very large intranet (over 100 different hosts / services) and will be stepping down from my role in the near future. I want to make things easy for the next victim person who takes my place. All hosts are secured via SSL. This includes various portals, wikis, data entry systems, HR systems and other sensitive things. We're using self signed certificates which worked o.k. in the past, but are now problematic because: Browsers make it harder for users to understand exactly what is going on when a self signed certificate is encountered, much less accept them. Putting up a new host means 100 phone calls asking what "Add an exception" means What we were doing is just importing the self signed certs when we set up a new workstation. This was fine when we only had a dozen to deal with, but now its just overwhelming. Our I.T. Department has classified this as ya all's problem, all we get from them is support for switch and router configurations. Beyond the user having connectivity, everything else is up to the intranet administrators. We have a mix of Ubuntu and Windows workstations. We'd like to set up our own self signed CA root, which can sign certificates for each host that we deploy on the intranet. Client browsers would of course be told to trust our CA. My question is, would this be dangerous and would we be better off going with intermediate certificates from someone like Verisign? Either way, I still have to import the root for the intermediate CA, so I really don't see what the difference is? Other than charging us money, what would Verisign be doing that we could not, beyond protecting the root CA cert so it can't be used to make forgeries?

• Install Mac OS Lion on Macbook with existing Ubuntu 12.04 dual boot

  - by kash

  I don't usually create my own questions, because I can find what I need through other people's questions. However, this one doesn't seem to be anywhere, except in one place where someone is talking about not using Apple hardware. So here it goes. I am using Apple hardware. I have a MacBook 1,1 with Intel Core2Duo running Ubuntu Precise Pangolin flawlessly. I never considered starting with Mac OSx and dual-booting because I never liked Mac OS. Now that I'm realizing that the only way I'm going to be able to run my DAW (Reaper) nicely and use a Firewire recording interface is to run Mac OSx, I'm considering it again. I want to go the opposite direction of most people and install Mac OSx next to an existing Ubuntu installation and have a boot menu with refit. I've installed refit in Ubuntu and I've converted the .dmg file for Mac OS Lion to a .iso file. Now, should I mount the .iso in Ubuntu and run it there, or burn a DVD and restart? I'm trying to gauge how to do this without hurting my existing Ubuntu installation. I will of course keep looking for existing answers in the meantime.

• Choppy USB mice on just one of USB ports

  - by user20532

  I've got Lenovo b560 laptop with latest, properly updated Kubuntu on it (11.04 natty, kernel 2.6.38-8-generic). It has three USB2.0 ports onboard. I usually plug a mouse into one of them (I've got 3 different mice - in office, at home and for when on the go). Sometimes, usually after laptop awakening from sleep, the mouse still works but cursor movements are choppy, as if the processor was extremely loaded (it's usually not). I found that if I re-plug the mouse cord into the other USB port, it works just fine. If I plug it back to problematic port, it is still choppy and remains choppy until next boot. Of course I want my mice to always work fine. Problem is: I cannot reproduce this behavior for sure, it happens sporadically but regularly. I use different USB ports (problem has ever happened on each of them since), I use different mice (each has failed me this way at least once), I cannot generally find what exactly is going wrong and why plugging to different port fixes the mouse instantly. So I'd like to hear at least clues where to look at, what to try to identify my problem. A bit of update: while beginning this post, I had the issue once again. I have just replugged the mouse back to problematic port and it is not recognized at all. On the other port it works smoothly.

• I created a program based on an LGPL project, and I'm not allowed to publish the source code

  - by Dave

  I thought LGPL was a permissive license, just like MIT, BSD or Apache. But today I read, that only linking to LGPL (libraries etc) is allowed from closed-source code - other than that, it's copyleft - so I have to publish code that is based on an LGPL program. I created a program for my employer that is based on an LGPL program, but has considerable modifications to it. Of course, I am not allowed to put that modified source code out there. At the same time, I have to, if I distribute it (right?). So I wonder whether there is a workaround to this, so I can keep this closed-source (I wish I could publish the source) - any suggestions? My idea: can I put most functions of the original LGPL app into an external library, write the core executable from scratch, but refer back to the library for all functions that I haven't modified? Currently, everything is in a .jar file (it's Java/Swing). if you think my idea is legally/technically feasible - how much effort would it be to seperate what I wrote and what the original is? I'm not the most java savvy.

• Uses of persistent data structures in non-functional languages

  - by Ray Toal

  Languages that are purely functional or near-purely functional benefit from persistent data structures because they are immutable and fit well with the stateless style of functional programming. But from time to time we see libraries of persistent data structures for (state-based, OOP) languages like Java. A claim often heard in favor of persistent data structures is that because they are immutable, they are thread-safe. However, the reason that persistent data structures are thread-safe is that if one thread were to "add" an element to a persistent collection, the operation returns a new collection like the original but with the element added. Other threads therefore see the original collection. The two collections share a lot of internal state, of course -- that's why these persistent structures are efficient. But since different threads see different states of data, it would seem that persistent data structures are not in themselves sufficient to handle scenarios where one thread makes a change that is visible to other threads. For this, it seems we must use devices such as atoms, references, software transactional memory, or even classic locks and synchronization mechanisms. Why then, is the immutability of PDSs touted as something beneficial for "thread safety"? Are there any real examples where PDSs help in synchronization, or solving concurrency problems? Or are PDSs simply a way to provide a stateless interface to an object in support of a functional programming style?

• Use C2WTS to get a classic windows identity from a claims identity

  - by Sahil Malik

  SharePoint, WCF and Azure Trainings: more information I know you’re going to find this useful at some point. A lot of backend systems still demand classic windows identities, but everything we do now has moved to claims. So sometimes (albeit rare), we have to translate a claims identity into a classic windows identity. This is where the “Claims to Windows Token Service” comes into play. SharePoint 2010 and 2013 make use of this but you can use this in any .NET application. First of all, there are some basic requirements for this to work, First, you will need the string value of a UPN claim. Just a string value, really! This means you can also use FBA or anything else. The “proper” way to do this of course is that you must originate this from a AD backed claim. So a user authenticated using ADFS or similar would be perfect. Just remember that you must issue the UPN claim. Read full article ....
