I want to select vertices by their indices (by vertex id) Like a python script,so that i can write the vertex id into it, and run the script,and it would automatically select those vertices   there is already an answer (python script) ,but it only works with one vertex when i tried with more than 2 vertices,it does not work :
How could I select one vertex from my mesh if I know ID of that vertex? I enabled bpy.app.debug = True and I can see all IDs but cant find a specific one.
How can you draw more detailed/smoother images in pygame? Im not familiar with Ubuntu or Linux in general but have succesfully installed dual-boot windows7/Ubuntu on a single harddisk on my private PC. I used the "Install Ubuntu alongside them"-option.   On my work PC I have an existing windows 7 64-bit installation that boots from BIOS firmware on a SSD drive (C:), and have my working data (documents etc) on a partition on a separate disk (D:). I now want to install Ubuntu (v 14.04.3) on the remaining unformatted space on D:\ using with the option of choosing system using GRUB. There are of cause fine descriptions around (e.g.  and ). My question is how to setup the partitions in the "something else"- option during the Ubuntu installation.   In  tutorial they assume that all partitions on the D-drive can be deleted; however I only obviously want to keep the working data on the existing D-partition, and place Ubuntu on the residual space (or part of it) on the D:-drive.  A) How is this ensured ? B) how many partitions should I make (boot, root, home, swap ?)  C) and should boot be made primary, and the others logical ? D) Should I set Device for boot loader installation as/dev/sdb - will this not erase the existing D-partion ? I tried to install wine using these commands: sudo apt-get install -y wine  And: sudo apt-get install wine  But terminal says that: Reading package lists... Done Building dependency tree        Reading state information... Done Package wine is a virtual package provided by:   winehq-staging 2.16.0~zesty   winehq-stable 2.0.2~zesty   winehq-devel 2.16.0~zesty   wine-development 2.0-3ubuntu1 You should explicitly select one to install.  E: Package 'wine' has no installation candidate  So there are 4 different version of wine. What is the difference between these versions. Which one is better? I wanted to install Internet Explorer from it and I installed winehq-stable. But I couldn't see that among applications in Winetricks. Do the other versions of wine have more applications to install? What is the difference? How do I get started playing Dungeons and Dragons 4th edition by myself? I've been wanting to start playing D&amp;D for some time, and I was wondering how I could get started by myself with relative ease. I own the first two player handbooks, and a set of dice. database disk image is malformed with dnf on Fedora 29 $\int_0^\infty \frac{\sin(x^2+ax)}{x}\,dx$ converges I want to show that the following converges for $a\ge 0$ $$\int_0^\infty \frac{\sin(x^2+ax)}{x}\,dx$$  We can show that $\lim_{x\to 0} \frac{\sin(x^2+ax)}{x} = a$, and with that fact it's straightforward to prove that $$\left|\int_0^\delta\frac{\sin(x^2+ax)}{x}\,dx \right|&lt; \infty$$ where $\delta &gt;0$ is a constant.  However I'm having trouble showing that the function decays quickly enough as $x$ goes to infinity. I know how to prove this when taking the integral of $\sin(ax)/x$, but that $x^2$ is causing me problems.  Any ideas? Thanks. MySQL Great Circle Distance (Haversine formula) I've got a working PHP script that gets Longitude and Latitude values and then inputs them into a MySQL query. I'd like to make it solely MySQL. Here's my current PHP Code:  if ($distance != "Any" &amp;&amp; $customer_zip != "") { //get the great circle distance      //get the origin zip code info     $zip_sql = "SELECT * FROM zip_code WHERE zip_code = '$customer_zip'";     $result = mysql_query($zip_sql);     $row = mysql_fetch_array($result);     $origin_lat = $row['lat'];     $origin_lon = $row['lon'];      //get the range     $lat_range = $distance/69.172;     $lon_range = abs($distance/(cos($details[0]) * 69.172));     $min_lat = number_format($origin_lat - $lat_range, "4", ".", "");     $max_lat = number_format($origin_lat + $lat_range, "4", ".", "");     $min_lon = number_format($origin_lon - $lon_range, "4", ".", "");     $max_lon = number_format($origin_lon + $lon_range, "4", ".", "");     $sql .= "lat BETWEEN '$min_lat' AND '$max_lat' AND lon BETWEEN '$min_lon' AND '$max_lon' AND ";     }   Does anyone know how to make this entirely MySQL? I've browsed the Internet a bit but most of the literature on it is pretty confusing. How to calculate $\lim_{n \to \infty}\sqrt[n]{\frac{2^n+3^n}{3^n+4^n}}$ I came across this strange limit whilst showing convergence of a series: $$\lim_{n \to \infty}\sqrt[n]{\frac{2^n+3^n}{3^n+4^n}}$$ How can I calculate this limit? Alias and functions From the bash manual     The rules concerning the definition and use of aliases are somewhat   confusing. Bash always reads at least one complete line of input   before executing any of the commands on that line. Aliases are   expanded when a command is read, not when it is executed. Therefore,   an alias definition appearing on the same line as another command does   not take effect until the next line of input is read. The commands   following the alias definition on that line are not affected by the   new alias. This behavior is also an issue when functions are executed.   Aliases are expanded when a function definition is read, not when the function is executed, because a function definition is itself a   compound command. As a consequence,   aliases defined in a function are not available until after that function is executed. To be safe, always put alias definitions on a   separate line, and do not use alias in compound commands.   The two sentences "Aliases are expanded when a function definition is read, not when the function is executed" and "aliases defined in a function are not available until after that function is executed" seem to be contrary to each other.  Can you explain what they mean respectively? Am wondering if somewhere there is a list of industry "minimums" for browser support. My company release two "portals" over the past 6 months and did very little to support IE8 users, who at this time, according to my G Analytics makes up about 14% of all IE visitors. Amazingly enough IE7 is 25%...  Figured support for IE7 was out the window already, but figured 14% was significant enough to warrant some support.  Any arguments to support my side of wanting to support IE8?  Any arguments to NOT support IE8? I have a bibliography in which a particular author wrote two papers in the same year.

How can I duplicate Apple's tiny USB power adapter? I'm designing a project that controls 110VAC (plug in, socket out), and also has a microprocessor inside.  I'd really like this project to not need a wall wart to get it's 5V, so I want to include a small DC power supply inside.    Apple's USB power adapter looks like a great small design that I can fit inside my case.  I'm guessing this is a switching power supply but I can't find any teardowns or schematics anywhere.  Does anyone know how this thing works?  I know I could make my own 110V->5VDC supply from a bridge rectifier and some caps, but I'd like to also be super safe.  What's in the Apple brick? Purpose of @ Symbol Before Strings? Sum of indepedent random variables and a constant Let $X_1$ and $X_2$ be independent Normal random variables with mean $\mu_1$ and $\mu_2$, and variances $\sigma_1$ and $\sigma_2$. Let $Y = X_2-X_1 + c$, where $c$ is a constant. For notational simplicity, let $Y = X' + c$, where $X' = X_2-X_1$ The moment generating function of a Normal random variable $X_n\sim N(μ_n,σ_n^2)$ is $$M_{X_n } (t)=\text{exp}\Big(μ_n t+\frac{σ_n^2 t^2}{2}\Big)$$ Then, $$M_{X'} (t)=\text{exp}\Big[t(\mu_1+\mu_2)+\frac{t^2}{2}(\sigma^2_1+\sigma^2_2)\Big]$$ Thus, by the uniqueness property of moment generating function, $X'$ is said to follow a Normal distribution with mean $(\mu_1+\mu_2)$ and variance $(\sigma^2_1+\sigma^2_2)$. How do I proceed from here to derive the following:  First, I want to establish that $Y$ is also a Normal random variable using the moment generating function. The constant $c$ bugs me, but I cannot ignore it. As per my understanding, $Y\sim N\big(c+\mu_1+\mu_2,\sigma^2_1+\sigma^2_2\big)$ (and I could be completely wrong). But I don't understand how to apply the moment generating function to prove that.  Secondly, I want to derive $P(Y \leq a)$, where $a$ is a constant. If I am not mistaken, $P(Y \leq a)$ can be written as $$P(Y \leq a)=\Phi\Bigg(\frac{a-X_2-X_1 + c}{\sqrt{2(\sigma^2_1+\sigma^2_2)}}\Bigg).$$ But how do I arrive at that.   Any help is high solicited and appreciated.
