How to change the size of desktop icons? I tried gconf-editor as given at  .  I am not getting the option for changing size at app &gt; nautilus &gt; icon_view.  I am using Ubuntu 11.10. Kindly help me in changing default icon size.   I want to make them small. Is there a way to exclude other particle systems from the effects of a Wind effect? I have a scene with a number of particle systems. I'd like to have a separate wind effect for my main scene and another for an extra: an emitter + wind-effect to blow leaves into my scene. I can't find any way to exclude, so here I am. At the very worst, I can just render the main scene and then render the wind effect and composite it, but I figured I'd check first. Avoiding Error 1325 EsriPyFldr not valid short file name when uninstalling ArcGIS for Desktop? I am trying to uninstall ArcGIS 10.3.1 for Desktop from Windows 7 SP1 using Uninstall a program and I am receiving an error message (pictured below):     Error 1325.

Feed randomly gone on SE Android app SE Android App Version: 1.0.84  There is a display issue in the Feed section. The Earlier today, the below sections and the post title are not visible.

I want the author's name displayed like this "Arter, D." instead of David Arter Where does top command get all the data for CPU Utilization? Interpretation of ROC curve I have a ROC curve like the figure below:   What can be inferred given this kind of curve in general?  What are the differences of states 1, 2 and 3 in the figure?  What causes the diagram to jump straight from state 1 to state 3? Most of the ROC curves on the internet look like the figure below: I want to make sure all of the data in my plugins/themes is handled securely  before entering the database and before being output to the browser. My problem is that there are situations where the API handles the sanitization for you -- like when saving post meta fields -- and others where the plugin/theme author is wholly responsible for doing it -- like when saving custom settings.  For the scope of this question, I'm not concerned about validating data at the domain level -- e.g., checking that an Age field on a form is between 0 and 120, or that an e-mail address is valid. I'm only concerned about security -- e.g., escaping SQL queries to avoid SQL injection when saving to the database, or sanitizing data that's output to HTML templates to avoid XSS.  For output sanitization, I know that you always need to use functions like esc_html() and esc_attr() when echo'ing variables into HTML templates. But, what about when using ? Do they all sanitize the output already? If so, for which context (general HTML, tag attributes, etc)? Some functions have variants for different contexts (like the_title_attribute(), but most don't.  For input sanitization, I know that I need to use $wpdb-&gt;prepare() when making manual queries, but what about when using the Settings API to create a plugin settings page, or saving post meta fields for a custom post type?  Right now I've just been digging through Core and reading tutorials every time I use a function to find out if it sanitizes or not, but that's error-prone and time consuming. I'm hoping to find some kind of comprehensive list of all the possible situations and whether or not the API handles it. e.g.,  API validates/sanitizes   Saving post meta with update_postmeta() Saving user meta with update_user_meta() Outputting a post title - use the contextually appropriate variant of the_title() etc   You have to manually validate/sanitize   Saving plugin options with the Settings API. Pass a callback as the 3rd parameter of register_setting(). Direct database queries: Wrap the query in $wpdb-&gt;prepare(). Outputting variables in HTML. Use esc_attr(), esc_html(), etc etc   I'd also be interested to understand why the API provides it in certain situations, but not others. I'm assuming it has something to do with the unknown nature of the data, but would love to hear a thorough explanation. which of the two it is? How to remove selected commit log entries from a Git repository while keeping their changes? I would like to remove selected commit log entries from a linear commit tree, so that the entries do not show in the commit log.  My commit tree looks something like:  R--A--B--C--D--E--HEAD   I would like to remove the B and C entries so that they do not show in the commit log, but changes from A to D should be preserved. Maybe by introducing a single commit, so that B and C become BC and the tree looks like.  R--A--BC--D--E--HEAD   Or, ideally, after A comes D directly. D' representing changes from A to B, B to C and C to D.  R--A--D'--E--HEAD   Is this possible? if yes, how?  This is a fairly new project so has no branches as of now, hence no merges as well.

Favicon of Earth Science and Spanish are too similar (exactly the same in HNQ list) The favicon is used in various places around the Stack Exchange (SE) network, to identify the site. Currently, Earth Science has  for main and  for meta. The problem I see is that these are awfully similar (i.e. exactly the same, as demonstrated here) to those for Spanish.SE, which are  for main and  for meta. The larger versions offer slight differences, but it's still hard to tell quickly which is which. Power users on this site, did you guess right, even after some time to think about it? (Answers under spoiler tag).   for main and  for meta.  for main and  for meta.    The first one is Earth Science and the second is Spanish.

An accountant we know told us this was incorrect. Can he deduct the amount placed in individual Ira? Subsubsection: remove the newline (like paragraph) Using the article document class, how can one remove the newline at the end of a subsubsection title?  I am using \documentclass{article}; I do not currently use titlesec or any of the alternatives; I do use fancyhdr. Let $f(z)$ be entire function. Show that if $f(z)$ is real when $|z| = 1$, then $f(z)$ must be a constant function using Maximum Modulus theorem Let $f(z)$ be entire function. Consider the functions $e^{if(z)}$ and $e^{−if(z)}$ and applying the Maximum Modulus Theorem, show that if $f(z)$ is real when $|z| = 1$, then $f(z)$ must be a constant function.  (We take $f(z)=u(z)+iv(z)$)  I am confused as so far I have $|g(z)|=|e^{if(z)}|=|e^{-v(z)}|$ and then since $f(z)$ is real, $f(z)=u(z)$ and $v(z)=0$ so I assumed it would follow that $|g(z)|=|e^{v(z)}|=1$.  Similarly, $|g(z)|=|e^{-if(z)}|=|e^{v(z)}|=1$.  Using Liouville I assumed one could say that both $g(z)$ and $h(z)$ are bounded entire functions, they are constant and so it follows that $v(z)$ is constant, meaning that both its partial derivatives are equal to 0 and, due to Cauchy Riemann, both of the partial derivatives of $u(z)$ are equal to zero.  It would then follow that $f(z)$ is constant.  I don't know how to go about the question using the Maximum Modulus Theorem, also I feel I am overlooking the importance of $|z|=1$ perhaps?

When trying to SSH into a particular Mac machine it gives me the following error :  ssh_exchange_identification: Connection closed by remote host   I have done some google searches on the issue but I haven't seem to find a definite answer.
