After writing I guess a 3 page essay describing my problem and after about a year of inactivity on stack exchange I remembered to sum up my problem, so please if you need more details tell me in the comments, and if is not the right place to ask please tell me too. My question is fairly simple, How does blender right now uses a CPU (2.8 or 2.9)? Is blender good at using high core counts of CPUs? and how much of an impact will more threads have on blender's performance. Now some context, I am upgrading from my computer bit by bit due to school and my budget, Unfortunately that is because of new blender versions requirements are higher, I picked up an entry level GPU and an SSD now I am searching for CPUs, I have always been loyal to Intel (Mine right now is a Core 2 Quad), but unfortunately the cheapest new i7 I could find of 8th or 9th gen was the budget of my whole computer, So I returned to i5s where my comparison is situated, I am comparing a a 6 core 12 thread intel i5-10400f cpu and an AMD Ryzen 7 2700X with 8 cores 16 threads, I didn't have any AMD cpu before and it is not that popular plus I use linux distributions of which AMD only fully support Ubuntu (I use Fedora), so question again: is higher threads and core counts matter in blender, or in other words what is the difference I will have for more thread and core counts? is it only in rendering? or also is calculations and simulations? And please if there is a detailed post/blog/manual describing this it would be helpful to mention it's link. Thanks is advance.
I wanted to get a 12 core CPU (Threadripper 1920X) and I wanted to know the max amount of cores Blender can use?
Android adware lets me opt out: is it safe? Recently my mom's phone running Android 5.0 has been infected with a piece of adware:    At first we thought this was caused by applications, but as you can see here, only the Google/METROPCS Internet browser is running.  In the photo, there is a button that reads 'opt out'. So I clicked on it and it took me to this link at http://tracker.tpc.re/optout/mobile/:    BUT both of these options smelly fishy. For starters, the manual app is not a download link in the play store but an APK, making it seem like a virus. The second (manual) as for sensitive information, which could harm me even more.   Which one of these options do I choose? Are they legit or do I have to do get rid of it another way? Removal of lines with no more or fewer than 'N' fields? It is generally believed and claimed that quantum computers can outperform classical devices in at least some tasks.  One of the most commonly cited examples of a problem in which quantum computers would outperform classical devices is $\text{Factoring}$, but then again, it is also not known whether $\text{Factoring}$ is also efficiently solvable with a classical computer (that is, whether $\text{Factoring}\in \text{P}$).  For other commonly cited problems in which quantum computers are known to provide an advantage, such as database search, the speedup is only polynomial.  Are there known instances of problems in which it can be shown (either proved or proved under strong computational complexity assumptions) that quantum computers would provide an exponential advantage? Graph editor for shape key animation I have animation where object changes his shape using shape keys, and I want to make some animation smoothing with graph editor. Is there a way to use graph editor for shape key animation? "At least one" - singular or plural subject? What is the purpose of the first test in an inductive proof? Learning about proof by induction, I take it that the first step is always something like "test if the proposition holds for $n = \textrm{[the minimum value]}$"  Like this:       Prove that $1+2+3+...+n = \frac{n(n + 1)}{2}$ for all $n \ge 1$.   Test it for $n = 1$:  $$n = \frac{n(n + 1)}{2} \implies 1 = \frac{2}{2}\textrm{, which holds.}$$  * The rest of the proof goes here *    So, I do it all the time (like a standard). But I never really thought about why. Why do I do such test? I can see that if the test does not hold, it cannot be proven by induction, I guess. But is there another reason we do this? Q&A Identification of seldom man-made physical objects not being piece of art? Is SE Q&amp;A format relevant for "identification of seldom physical objects observed in real world"?  Questions like "I do not know function of this object (picture) - which purpose does it have?"  In many cases I suppose these question could have civil engineering or handcraft i.e. cultural/historical background. In second case "SE history" might be okay. For first case, I do not know.

This click data is currently being evaluated to see what we can do with it. Ideas welcome! Using a diode to ensure current flows in only one direction, without causing a voltage drop To power my microcontroller (ATmega8), I am using a ~5.4V voltage source. I want to ensure that I don't accidentally connect the voltage source in reverse, and figured a diode would be a nice way to accomplish this as from what I have learned so far, a diode allows current to flow in one direction, and blocks it in the other.  But what I also learned is that diodes create drops in voltage. I have a few of the typical diodes (1N4001, 1N4148, etc.), and would like to use them to achieve the aforementioned result without dropping the voltage as it would be too low to power the IC.  My question is, is there any way to do this with a diode? Or do I need some other component (if so, what would you recommend)? conflict between hyperref and enumitem packages (and \refstepcounter) The solution outlined for each of the following two posts appears to conflict with the hyperref package.         Here is a MWE.  The desired output for the example is  1. Outer 2.1. This is line 2.1, in block 2.  2.2. Inner again 3. Outer again 4. Let’s end here   This output is indeed produced by the LaTeX source below, but if I uncomment the \usepackage{hyperref} line in the header, LaTeX gives me an error just after the \skipitem command, as described in the inline comment below:  \documentclass{article}  % \usepackage{hyperref} % if we uncomment the above line, we get an error as described below  \usepackage{enumitem}  \newlist{steps}{enumerate}{9} \setlist[steps]{itemindent=0pt} \setlist[steps,1]{label=\arabic*.,ref=\arabic*} \setlist[steps,2]{label=\arabic{stepsi}.\arabic*.,ref=\arabic{stepsi}.\arabic*}  \makeatletter \newcommand{\skipitem}{\refstepcounter{\@enumctr}} \makeatother  \begin{document} \begin{steps} \item Outer   \skipitem   % If we uncomment the \usepackage{hyperref} line in the header,   % we get the following error after the \skipitem above   %    % ./tmp.tex:20: Missing number, treated as zero.   % &lt;to be read again&gt;    %   \c@0.0ptxcii    % l.20   \skipitem   % \item[] \label{blockA}   \label{blockA}\item[]   \begin{steps}   \item\label{lineB} This is line~\ref{lineB}, in block~\ref{blockA}.   \item Inner again   \end{steps} \item Outer again \item Let's end here \end{steps}  \end{document}   Can someone help me work around this conflict, so I can use hyperref with this use of enumitems and refstepcounter?  Thanks.  (Note: smaller working examples are possible, but they give different error messages.  I'm hoping to get the current example working.) Is it possible to add new alphabets to unicode-math? In ordinary LaTeX, one can easily add new math alphabets by using \DeclareMathAlphabet. One is then able to use, say, cmsy, eus, and rsfs letters side-by-side. Unfortunately, there does not seem to be a similar mechanism in unicode-math, or at the very least \DeclareMathAlphabet doesn't do what it's supposed to do.  Question. How can I set up my own math alphabets in unicode-math?   Attempted workarounds  Since unicode-math has lots of math alphabets, one workaround might be to replace an unused alphabet with the desired one using \setmathfont[range=...-&gt;...]. This doesn't quite work right in my example:  \documentclass[12pt]{article} \usepackage{fontspec,xltxtra,xunicode} \defaultfontfeatures{Mapping=tex-text}  \usepackage{unicode-math}  \scrollmode  \setmathfont{xits-math.otf} \setmathfont[range={\mathscr,\mathbfscr},StylisticSet=0]{xits-math.otf} \setmathfont[range={\mathcal,\mathbfcal},StylisticSet=1]{xits-math.otf} \setmathfont[range={\mathtt-&gt;\mathcal}]{latinmodern-math.otf}  \begin{document} \[ \begin{array}{c} \mathcal{A B C D E F G H I J K L M N O P Q R S T U V W X Y Z} \\ \mathscr{A B C D E F G H I J K L M N O P Q R S T U V W X Y Z} \\ \mathtt{A B C D E F G H I J K L M N O P Q R S T U V W X Y Z} \end{array} \]   I suspect the problem is that the codepoints of the calligraphic letters in Unicode are not contiguous.   Using \mathversion seems to work better:  \documentclass[12pt]{article} \usepackage{fontspec,xltxtra,xunicode} \defaultfontfeatures{Mapping=tex-text}  \usepackage{unicode-math}  \setmathfont{xits-math.otf}  \setmathfont[version=eucal]{latinmodern-math.otf} \newcommand{\eucal}[1]{\mathchoice %   {\mbox{\mathversion{eucal}$\displaystyle\mathscr{#1}$}} %   {\mbox{\mathversion{eucal}$\mathscr{#1}$}} %   {\mbox{\mathversion{eucal}$\scriptstyle\mathscr{#1}$}} %   {\mbox{\mathversion{eucal}$\scriptscriptstyle\mathscr{#1}$}}}  \setmathfont[range={\mathcal,\mathbfcal},StylisticSet=1]{xits-math.otf}  \begin{document} \[ \begin{array}{c} \mathcal{A B C D E F G H I J K L M N O P Q R S T U V W X Y Z} \\ \mathscr{A B C D E F G H I J K L M N O P Q R S T U V W X Y Z} \\ \eucal{A B C D E F G H I J K L M N O P Q R S T U V W X Y Z} \end{array} \] \end{document}   But this feels very inefficient. Complete classification of the groups for which converse of Lagrange's Theorem holds Disable RAM stick in Windows 7 I have 2 8gb RAM sticks on my motherboard. One is faulty on some bytes and is giving me BSOD once in a while.  Is it possible to disable one of them without removing it physically? I want to keep it inside the motherboard as I dual boot with Xubuntu and I can block the fauly bits there, and as far as I know, it is impossible to block them in Windows. Recursively rename files and directories I want to subtract the current frame from a previous frame, I have a image sequence and I want blender to subtract the current frame from the frame with an offset of -4. If I am on frame 5 so blender will subtract and use frame 1. Make hyperref take pdfinfo from \title and \author I once read about an option for hyperref that automatically takes the info provided via the standard \author and \title, and puts it into the pdfinfo. Now I want to implement it in my template and can't find it anywhere in the hyperref manual nor anywhere else.  Did I dream about this or can someone help me out here?  (A similar, but more general question: ) Is it possible to use NBT tags in commands in Minecraft: Bedrock Edition? This question was recently split into different questions for each workaround. See   meta posts for more information.   Can you use NBT tags in commands? I’ve tried commands that normally work in Java Edition like: give @s minecraft:planks 30 1 {display:{Lore:[&quot;Wooden planks&quot;]}} give @s stone_pickaxe{Unbreakable:1b} give @s item_frame{EntityTag:{Invisible:1b}} summon villager ~ ~ ~ {Offers:{Recipes:[{buy:{id:&quot;emerald&quot;,Count:5b},sell:{id:&quot;diamond_sword&quot;}}]}} summon tnt ~ ~ ~ {Fuse:20s} What is the joint distribution of $Z=\min(X,Y)$ and $I_{Z=X}$? Assume that $X$ and $Y$ are independent random variables with $X \sim \exp(\lambda)$ and $Y \sim \exp(\mu)$. It is impossible to obtain direct observations of $X$ and $Y$. Instead, we observe the random variables $Z$ and $W$, where $Z = \min\{X,Y\}$ and $W =1$ if $Z=X$ and $W=0$ if $Z=Y$.  How to find the joint distribution of $Z$ and $W$? Where does Minecraft for Windows 10 store its data? I have searched in %appdata%, pulling up the list of files there, but there is no file labelled .minecraft. Searching %appdata%\.minecraft returns "no results found".   I also opened Minecraft to click on the resources button and could not locate that either.
