I have a project in Blender that provokes a shape to move in certain ways based on two values (currently I manually change the values in the Python script in Blender and manually click to render to an MP4 file). The goal in mind is to have a web page that collects these two values and passes them into Blender to render a video (MP4) and write it out to a certain location. Essentially I want to automate the render upon the opening of this particular blender file.  I am relatively new to Blender, but I did notice that when I move my cursor over each setting, Python code is displayed. I have been trying to reference that code and the online documentation to auto-render, but I not having any luck.    The command shown to render is bpy.ops.render.opengl(animation=True). However, I am confused on where I would need to place this line of code to initiate the render. I have a python script that will open up blender and my blender file, but I just need a little guidance on how to pull off this next process.
Let's say we have a Python script my_script.py that does some data processing with Blender. This script accepts some arguments (e.g. arg1 arg2). How can I forward arguments to the script when using it with the CLI?  blender --background --python my_script.py   The only trick I could find was :  echo "arg1 arg2" &gt; my_input.txt &amp;&amp; blender --background --python my_script.py   Is this really the only way to do that?  Update  I found a  on Stack Overflow.
How to align content of a div to the bottom Say I have the following CSS and HTML code:    #header {   height: 150px; } &lt;div id="header"&gt;   &lt;h1&gt;Header title&lt;/h1&gt;   Header content (one or multiple lines) &lt;/div&gt;     The header section is fixed height, but the header content may change.  I would like the content of the header to be vertically aligned to the bottom of the header section, so the last line of text "sticks" to the bottom of the header section.  So if there is only one line of text, it would be like:   ----------------------------- | Header title | | | | header content (resulting in one line) -----------------------------   And if there were three lines:   ----------------------------- | Header title | | header content (which is so | much stuff that it perfectly | spans over three lines) -----------------------------   How can this be done in CSS?

How to check if a string starts with a specified string? (a) Solve the equation $yu_x+xu_y=0$  with the condition $u(0,y) = e^{-y^2}$. (b) In which region of the xy plane is the solution uniquely determined?     I did the first part but I don't understand how to do part b.  I read   But I don't understand how the argument is based. A more clear explanation is appreciated Accuracy Vs. Precision  What I would like to know is whether I should use System.currentTimeMillis() or System.nanoTime() when updating my object's positions in my game?  Their change in movement is directly proportional to the elapsed time since the last call and I want to be as precise as possible.  I've read that there are some serious time-resolution issues between different operating systems (namely that Mac / Linux have an almost 1 ms resolution while Windows has a  50ms resolution??).  I'm primarly running my apps on windows and 50ms resolution seems pretty inaccurate.  Are there better options than the two I listed?  Any suggestions / comments?

Performance of try-catch in php What kind of performance implications are there to consider when using try-catch statements in php 5?   I've read some old and seemingly conflicting information on this subject on the web before. A lot of the framework I currently have to work with was created on php 4 and lacks many of the niceties of php 5. So, I don't have much experience myself in using try-catchs with php. Setup Apache in Amazon AWS I tried to setup apache 2.2 in amazon aws using amazon ami. i did installed httpd and php and congirue http.conf to use /var/www/html.  Then put file index.html on that folder. But when i tried to use browser to browse my domain which is ec2-122-248-255-181.ap-southeast-1.compute.amazonaws.com, nothing was loaded.  I did start httpd by running apachectl start, and i can see it listening on port 80.  Does anybody know what is wrong? Creating if-else condition with ArcGIS API for JavaScript combo boxes? I'm a software developer and as such I build and run programs hundreds of times per day. I've noticed that since I started using Catalina, after compiling and linking there is a delay (which can be seconds) when the internet is slow or having problems (I have bad internet often). If I disable wifi and rebuild, the delay goes away. How can I disable this so my builds run faster? Last month, I was travelling on a backpacking trip across Russia and the Baltic states (Schengen zone). I'm an Indian by nationality. So I had to get the respective single entry visa for Russia and Schengen Europe.  At the border crossing into Estonia by road (at Ivangorod-Narva), I exited the Russian border with an exit stamp (so now I can't go back to Russia since I had a single entry visa). When I was at the immigration checkpoint of Estonia, I was heavily questioned on the intent of my travel to Europe while entering Estonia by road.   Though I finally got into Europe, It got me wondering - what happens if a foreign national is denied entry into a country not at the airport but by land between 2 countries he cannot go into ?  Generally, if you are denied entry at the airport the airline has the obligation to fly you back to your country. But what happens when you are stuck between two countries and you cant get into either ? What happens to you then ? Group presentation for discrete Heisenberg group Show that if $\sup\big\{\sum\lvert\, f(a)\rvert\big\}  0\}$ is countable. Let $f:A \to \mathbb R$ and suppose that $$ \sup\Big\{\sum_{a\in F}\lvert\, f(a)\rvert :  F\text{ is finite subset of }A\Big\} &lt; \infty $$ then the set $\{ a \in A : f(a) &gt; 0\}$ is countable.  My try: Define these element of ${ a ∈ A : f(a) &gt; 0}$, then $∑_{n=1}^\infty\lvert\, f(a_n)\rvert$ is determined, regardless of the method of arrangement.

Elementary argument for conservation laws from symmetries *without* using the Lagrangian formalism It is well known from Noether's Theorem how from continuous symmetries in the Lagrangian one gets a conserved charge which corresponds to linear momentum, angular momentum for translational and rotational symmetries and others.  Is there any elementary argument for why linear or angular momentum specifically (and not other conserved quantities) are conserved which does not require knowledge of Lagrangians? By elementary I mean, "if this is not so, then this unreasonable thing occurs".   Of course, we can say "if we want our laws to be the same at a different point in space then linear conservation must be conserved", but can we derive mathematically the expression for the conserved quantity without using the Lagrangian?  I want to explain to a friend why they are conserved but he doesn't have the background to understand the Lagrangian formalism.
