Is it not possible to use Dynamic binding of sObject fields in a Lightning Component? I'm trying to loop a list of sObject fields and displaying the fields as column in a table.  In Visualforce, we could bind an sObject field like value="{!Contact[fieldName]}". But I'm unable to make this happen in a Lightning Component.  I'm trying to output my field data like this:  &lt;aura:iteration items="{!v.contactColumns}" var="col"&gt; &lt;td&gt; &lt;ui:outputText value="{!'contact.' + col.fieldName}"&gt;&lt;/ui:outputText&gt; &lt;/td&gt; &lt;/aura:iteration&gt;   But it is displaying Empty output, without any value.  Am I doing it wrong in preparing dynamic field value binding for ui:outputText in above code?  Ive even tried using force:outputField without any luck and same empty value output:  &lt;force:outputField value="{!'contact.' + col.fieldName}" /&gt;
Lightning aura:iteration over two objects with dynamic key I want to do simple thing - I want to iterate over list of two objects and use displayColumns as dynamic keys to get values from selectList object:  &lt;aura:attribute name="displayColumns" type="String[]"/&gt; &lt;aura:attribute name="selectList" type="Object[]"/&gt;   &lt;table&gt;     &lt;aura:iteration items="{!v.selectList}" var="elem"&gt;     &lt;tr&gt;         &lt;aura:iteration items="{!v.displayColumns}" var="col"&gt;             &lt;td&gt;{!elem[col]}&lt;/td&gt;         &lt;/aura:iteration&gt;     &lt;/tr&gt;     &lt;/aura:iteration&gt; &lt;/table&gt;   In pure JS I would do: elem[col.value], but in lightning compiler returns:      expecting a positive integer, found 'col' at column 6 of expression:   elem[col.value]: Source   Is there any workaround without creating proper object structure in controller?
Autodesk Maya symbol lookup error on start after installing AMD proprietary driver on Ubuntu 18.04 I've installed Maya 2018 on Ubuntu 18.04 and tested it with the amdgpu driver (open source) and it launched without problems, but some components were not working with the open source driver so I tried amd gpu pro 18.20 (amd closed-source driver). I ran  ./amdgpu-pro-install   but since then Maya won't work and gives this warning message:  ./maya.bin: symbol lookup error: /usr/autodesk/maya2018/bin/.. /lib/libOGSDeviceOGL4-16.so: undefined symbol: EVP_CIPHER_CTX_init   My card is hd7770 and it's supported by the amd closed driver, so what am I doing wrong? I have scripts calling other script files but I need to get the filepath of the file that is currently running within the process.   For example, let's say I have three files. Using :   script_1.py calls script_2.py.  In turn, script_2.py calls script_3.py.    How can I get the file name and path of script_3.py, from code within script_3.py, without having to pass that information as arguments from script_2.py?  (Executing os.getcwd() returns the original starting script's filepath not the current file's.)

Error message on Terminal launch How do you start Windows 10 in safe mode? I've been through the Windows 10 upgrade, and am experiencing a recurring "INTERNAL_POWER_ERROR", which is stopping me from logging in.  I'd like to be able to try to boot to safe mode, but it appears that pressing F8 during boot is no longer enough, so how can I boot in safe mode (or any of the other recovery options) on a Windows 10 PC that doesn't let me log on?

For example, this: Hello ---- this is some other text  renders as this: Hello this is some other text This is fine and works well. When I want to quote that text is when the problem arises, since this Markdown: &gt; Hello &gt; ---- &gt; this is some other text  When written down shows well in the preview but not when posted:  Hello this is some other text   As an example, see an screenshot of the preview:    and a screenshot of the posted content, where the ---- becomes a &lt;hr&gt;:  Note a similar bug I also reported: .

How to run Windows 10 from an external hard drive? I am currently able to boot from an external drive or multiboot USB. Taking this concept one step further, I have 3 questions:   1) Is it possible to install and run Windows 10 on a portable external hard drive or USB card with the same functionality of being installed on the internal drive?   2) Is it considered legal to do so or will it affect Windows updates in any way?   3) What are the steps to do that? (please outline steps I can follow so I don't lose a drive in the process). :)  EDIT: My question deals specifically with Windows 10, the legality and method of making it a standalone OS running from an external device and what effect if any it has on Windows Update; questions not dealt with in the other question.
