Need someone to clear up my mind about the CP of Pokemon
Factors for max CP at a particular trainer level?
What is necessary and/or sufficient for polynomials to provide isomorphic quotient rings? How to install folding at home (Folding@home FAHControl) on Ubuntu 19.10 Back in the dark days when I used to run windows I used to use MindJet Mindmanager and I found it to be very good.  Since I have been using Ubuntu as my main operating system I have been trying to find a replacement mind map software to use but have not had any luck finding a good replacment.  So far I have tried VYM, kdisset and Semantik. I have either found them not to be very good or have a nasty habit of crashing.   So I was wondering could anyone recommend good mind mapping software to use under Ubuntu? Optimal estimation of a single parameter given data at different scales Let $A,B,C,D$ be independent normal random variables distributed according to $\mathcal{N}(0,\sigma^2)$ and $E = A+B+C+D$.  The goal is to provide an optimal estimate of $\sigma^2$ given samples of $A,B,E$ but not $C,D$.  In this case optimal refers to minimising the root-mean square deviation of the estimate $\hat{\sigma}^2$:  $$RMSD(\hat{\sigma}^2) = \sqrt{\mathbb{E}\left[\left(\hat{\sigma}^2-\sigma^2\right)^2\right]}$$  I can think of a simple approach to estimate $\sigma^2$ given samples of $A,B$ which is to simply compute the sample variance. Also I know that the variance of $E$ is $4\sigma^2$ so I could compute the sample variance of $E$ and divide it by 4 to get an estimate of $\sigma^2$. However it should be possible to combine the information from both $E$ and $A,B$ to improve estimation $\sigma^2$. Could you outline the approach to use both sets of information? $$\lim_{x\to 0} \frac{\ln(1+x)}x$$  The process I  want to take to solving this is by using the definition of the limit, but I am getting confused. ( without l'hopitals rule)   $$\lim_{h \to 0} \frac{f(x+h) - f(x)}h$$  $$\lim_{h \to 0} \frac{\frac{\ln (1+x+h)}{x+h} - \frac{\ln(1+x)}x}h$$  $$\lim_{h \to 0} \frac{x\ln(1+x+h) - (x+h)\ln (1+x)}{hx(x+h))}$$  At this point I get confused because I know the answer is $1$, but I am not getting this answer through simplification of my formula. How do you join on the same table, twice, in mysql? I have 2 tables. One (domains) has domain ids, and domain names (dom_id, dom_url).  the other contains actual data, 2 of which columns require a TO and FROM domain names. So I have 2 columns rev_dom_from and rev_dom_for, both of which store the domain name id, from the domains table.  Simple.  Now I need to actually display both domain names on the webpage. I know how to display one or the other, via the LEFT JOIN domains ON reviews.rev_dom_for = domains.dom_url query, and then you echo out the dom_url, which would echo out the domain name in the rev_dom_for column.  But how would I make it echo out the 2nd domain name, in the dom_rev_from column? I can see by manipulating the expression why $\mathbb{E}X$ works out to be $\int_0^\infty 1-F(x)\,dx$, where $F$ is the distribution function of $X$, but what is an intuitive explanation for why that is true? If at each point we sum the probability $\mathbb{P}(X&gt;x)$, why should we end up with the expectation?  Thanks I was curious about how other people use the this keyword. I tend to use it in constructors, but I may also use it throughout the class in other methods. Some examples:  In a constructor:  public Light(Vector v) {     this.dir = new Vector(v); }   Elsewhere  public void SomeMethod() {     Vector vec = new Vector();     double d = (vec * vec) - (this.radius * this.radius); } Possible to lock focal length on zoom lens? (SELP1650) (This could turn out to be a bone, practical, product-specific query, but this is the internet so the worst that could happen is a 0 rather than a 1.)  Anyhoo: is it possible to lock a zoomable lens to a certain focal length? Is this a typical feature for a lens?  I want to keep my SELP1650 at X mm to help with some creative experiments, but the thing shifts whenever I move my hand against the lens ring. Does SELP1650 (or the body, Sony A6000) specifically have this option?  Or... is there a reasonably non-goofy DIY trick I could pull off, without bricking the thing? (anticipating a sarky 'duct tape' suggestion) force long text inside \item[{\texttt{}] to wrap Recording iPad screen using QuickTime I need to record a demo on my iPad's screen where I narrate what's going on but I also want the sounds from the iPad to be in the video. It seems that choosing the Mac Built-in Mic option causes only my voice to be in the video while choosing the iPad Mic option cause only the sounds from the iPad to be in the video. What can I do to put both in the video? Is there a Stack Exchange site for both technical and behavioural interview questions? Where I could ask questions about, for example:   Sample questions and solutions, experiences, or seeking advice for interviews A place where I could ask interview questions and what the best way to answer it (not just a correct way or the most efficient).   What to do in a certain situation such as negotiation, unfair interviews, etc.   Experiences interviewing at so-and-so company. Human-readable filesize with find's printf What does = +_ mean in JavaScript Cannot get onto Apple Developer Forums Every time I attempt to log on to the apple developer forums it tells me I need to create a new user account (even though I already have one), and when I try to sign up it gives me an error:   Anyone else have this issue and/or know how to fix it? Thanks! Unable to check a mdadm RAID1 array, says the file system's read only? I recently migrated a RAID1 from a CentOS 5 system to a CentOS 6 system and ever since when I attempt to perform a check I get the following:  $ echo 'check' &gt; /sys/block/md127/md/sync_action -bash: /sys/block/md127/md/sync_action: Read-only file system   This actually shows up from a CRON too, specifically, /etc/cron.d/raid-check. this is included in the mdadm RPM:  $ rpm -ql mdadm | head -5 /etc/cron.d/raid-check /etc/rc.d/init.d/mdmonitor /etc/sysconfig/raid-check /lib/udev/rules.d/63-md-raid-arrays.rules /lib/udev/rules.d/65-md-incremental.rules   Here I'm running the same command that's used by the CRON:  $ raid-check /usr/sbin/raid-check: line 96: /sys/block/md127/md/sync_action: Read-only file system   This typically runs once a week and sends an email which is what originally alerted me to the issue. But at any rate I'm at a loss why this RAID seems to be unable to be checked.  The RAID seems fine on inspection though.  $ cat /proc/mdstat  Personalities : [raid1]  md127 : active raid1 sda1[0] sdb1[1]       976759936 blocks [2/2] [UU]  unused devices: &lt;none&gt;   I point this out only because while googling I found this thread regarding a bug in mdadm but this was for a older version of mdadm.      Version info  $ lsb_release -d Description:    CentOS release 6.6 (Final)  $ rpm -q mdadm mdadm-3.3-6.el6_6.1.x86_64  $ mdadm --version mdadm - v3.3 - 3rd September 2013 In the discussion from a question I asked several days ago (), someone suggested that I use general.runalg() instead of processing.runalg() for running QGIS algorithms.    I've now used both, and haven't noticed a difference in either performance or syntax between them.  I'm just wondering what sort of differences there are between these two methods, and which one I should be using. How to print object content in correct way? Show that $\frac{1}{\sqrt{2\pi}} \cdot \left(\int_{- \infty}^{\infty} e^{itx} \cdot e^{-\frac{1}{2}t^2 } dx \right) = e^{-\frac{1}{2}t^2}$ I am struggling to show that $$\frac{1}{\sqrt{2\pi}} \cdot \left(\int_{- \infty}^{\infty} e^{itx} \cdot e^{-\frac{1}{2}x^2 } dx \right) = e^{-\frac{1}{2}t^2}$$  In the same paper we defined  $$F(t):=\left(\int_0^t e^{-x^2}\right)^2 \quad \text{ and} \quad  G(t):=\left( \int _0^1\frac{e^{-t^2(1+x^2)}}{1+x^2} \right)$$  I showed that both functions are differentiable with  $$F'= 2e^{-t^2} \cdot \int_0^t e^{-x^2}$$ $$G' = -2te^{-t^2} \cdot \int_0^1 e^{-x^2t^2}$$  It follows that $F' + G' = 0$ and $F + G = \frac{\pi}{4}$  With that I showed that $\int_{-\infty}^{\infty} e^{-x^2} = \sqrt{\pi}$.  Any help is appreciated. Why does magnetic force vary in proportion to the cube of the distance instead of the square? Magnetic forces vary from gravity and electromagnetic radiation (such as light) in that gravity and radiation diminish by the square of the distance from the source, but magnetism diminishes by the cube of the distance.  Why is this?
