"do it themselves" or "do it by themselves"
Difference between myself and by myself
How do I fill arrays in Java? I know how to do it normally, but I could swear that you could fill out out like a[0] = {0,0,0,0}; How do you do it that way? I did try Google, but I didn't get anything helpful. Why does the Cauchy distribution have no mean? How to get a cross-origin resource sharing (CORS) post request working Is it possible to decompose a hermitian and unitrary matrix $A$ into the sum of the Pauli matrix Kronecker products?   For example, I have a matrix 16x16 and want it to be decomposed into something like $$A =\sum_{i,j,k,l}h_{ijkl}\sigma_i\otimes\sigma_j\otimes\sigma_k\otimes\sigma_l$$ I can't find any clear explanation how it can be done. I found only this for two-dimentional case: For some reason, the profile-hover view thingy is not loading at all(on Stackoverflow). I initially thought that it might be because of , but its been closed with the status, no-repro. Also, this is now persisting for the past 1 hour for me.  I tried to clear the cache and stuffs but nothing seems to be working, as the hover view is still not loading. Is this some sort of  or an issue with the browser? I'm using Firefox 25.0.1 on Win7 Pro(x86) machine. Here is a snapshot of it. Photoshop CS6 Resize Rectangle with Rounded Corners This question is about Photoshop CS6. Hopefully the feature was added in this version. Before posting I looked up Google and  and  but didn't find an answer for CS6.  So the question is: Is there a feature within CS6 or a script that allows to resize a vector element with rounded corners without using the Direct Selection Tool (white arrow tool) and not changing the border radius? What would be great would be something like simply using the transform tool or something like a grid resize tool. With the new permission model for Marketing Cloud Installed Packages, there is a problem with the "Read"-Scope for Data Extensions.

I have bound an event listener using the observe method, but I would also like to be able to fire the event programatically.  Thanks in advance How to use the Bradhley Hand font? I've checked the  that can be used through beamer class. I've successfully used most of the fonts, but when I tried to include the Bradhley Hand font, it did not work (it shows ordinary characters)?! How can I use it?  For example, when I use the following :  \documentclass[serif]{beamer}  \usepackage{mathpazo}  \renewcommand{\rmdefault}{ibh}  \begin{document} \begin{frame} $\frac{ \sqrt{ \mu(i)^{ \frac{3}{2}} (i^{2} -1) } } { \sqrt[3]{\rho(i) - 2} + \sqrt[3]{\rho(i) - 1} } $ \end{frame} \end{document}   it gives: What is the bug about: Keyword gets duplicated even when the query is not modified.  Impact: As far as i can tell - cosmetic.  How to replicate: Go to:  and keep pressing Search button. With each search there will be a duplicate python keyword appended to search box.  Best guess for what is causing it: I think you have somewhere a piece of code that appends tag as a keyword without checking if it is already present. My reasoning comes from this url:  not having the same issue - the tag is not present in it.

I'm using bash on Mac OS X. Now that I have Google Chrome all set up, I got myself a new laptop. Does anyone have any idea how to transfer my settings, cookies, favorites, etc?   I checked documents and settings\me\application data, and found nothing. In many experiments in quantum mechanics, a single photon is sent to a mirror which it passes through or bounces off with 50% probability, then the same for some more similar mirrors, and at the end we get interference between the various paths. This is fairly easy to observe in the laboratory.  The interference means there is no which-path information stored anywhere in the mirrors. The mirrors are made of 10^20-something atoms, they aren't necessarily ultra-pure crystals, and they're at room temperature. Nonetheless, they act on the photons as very simple unitary operators. Why is it that the mirrors retain no or very little trace of the photon's path, so that very little decoherence occurs?  In general, how do I look at a physical situation and predict when there will be enough noisy interaction with the environment for a quantum state to decohere? How to install ubuntu on lenovo g580? I'd like to install Ubuntu 13.04 on Lenovo g580 and I have this issue. After a few seconds of booting liveUSB screens gets black and nothing happens. I've read somewhere about connecting second screen to solve similar issue. Of course this didn't solve it, but it provided something like terminal with     initramfs>   and few basic commands ..  Is it possible to install Ubuntu on Lenovo g580 hardware? I also checked  Ubuntu 12.04: failed  Mint 13: SUCCEED (x32 and x64)  Is it because of drivers? Of course I want Ubuntu instead of Mint. :) Expressions - is there an easy and "visual" way to combine them into another expression? I have a small issue with configuring the lidR  for parametrizing the extracted raster files with grid_metrics() function.  My question is how to set in the catalog options that:   be able to overwrite the results with a second run if I want to run my script several times and I do not want to name each output differently. instead of .tif I would like to get .grd files as output.   My current code (which is working) is the following:  normalizedctg = catalog(workingdirectory) opt_output_files(normalizedctg) &lt;- paste(workingdirectory,"/clipped/normalized/{XLEFT}_{YBOTTOM}_height",sep="") height = grid_metrics(normalizedctg, max(Z),res = resolution)   But with a second run on the same code I get the following error:  Error in .getGDALtransient(x, filename = filename, options = options,  :    filename exists; use overwrite=TRUE Consider an isosceles triangle. Let r be the radius of the circumscribed circle and p be the radius of the inscribed circle. Prove that the distance d between the centers of these two circles is $$d = \sqrt{r(2p-r)}$$ How to wrap lines in a jtable cell? Is there an easy way to tell if a graph can be embedded on a Möbius strip (with no edges crossing)?  A specific version of this: if a simple graph with an odd number of vertices has all vertices of degree 4, can it be embedded on a Möbius strip?    Answer summary:   There are  for the Möbius strip that are   and drawn on . There are  for the Möbius strip, they are , and even better there are only .   I have not yet answered the second question, but Jim Belk's excellent explanation has given me good ideas. What is the best symbol to use for the d'Alembertian? Normally, most people use the symbol $\Box$ to represent the  (including the linked to Wikipedia page).  Recently I wanted to use \hat\Box and \tilde\Box, but they do not render very well.    What is the "best" way to create such symbols?    Aside: The above image is rendered using my local install of pdflatex: pdfTeX 3.1415926-1.40.10-2.2 (TeX Live 2009/Debian). The symbols seem to render fine on some online services: e.g. "" produces    from   \begin{align*} \Box &amp;= \sum_a \partial^a\partial_a \,, &amp; \hat\Box &amp;= \sum_a \mathcal{D}^a\mathcal{D}_a \end{align*}
