I have read the question  and confirmed that my configuration works fine with valid non-Freetype font names as passed to, e.g., xfontsel. However, I would like to use Freetype fonts instead.  With urxvt I specify my font as xft:Source Code Pro:size=9 in my X resources; the same specification works fine when given directly with the -fn command line option.  However, if I use the same specification with the -f option to cssh or the terminal_font setting in .clusterssh/config I get an error message:  Fatal: Unrecognised font used (xft:Source Code Pro:size=9). Please amend $HOME/.clusterssh/config with a valid font (see man page).   How can I specify this font to ClusterSSH?  (For those whom might be helped by a look at the source code, the error originates in the get_font_size() function of /usr/share/perl5/App/ClusterSSH.pm on my system; I suspect it's the $xdisplay-&gt;QueryFont($font); call that's failing.)
In my cssh config file, I have:  terminal_font=6x13   this default font is too small for me.   man cssh says, I can specify other font size with the -f argument, while using "standard X font notation".  is a wikipedia page containing some other fonts types. Unfortunately, none of these work for me:  $ cssh host1 host2 -f "7x14" Fatal: Unrecognised font used (7x14). Please amend $HOME/.clusterssh/config with a valid font (see man page).   Why does "7x14" not work?  How can I use bigger fonts with cssh ?
We have no mention of Voldemort in Harry's sixth year. So, I was wondering- what could Voldemort have been doing? Calculating the limit $\lim((n!)^{1/n})$ Find $\lim_{n\to\infty} ((n!)^{1/n})$. The question seemed rather simple at first, and then I realized I was not sure how to properly deal with this at all. My attempt: take the logarithm,  $$\lim_{n\to\infty} \ln((n!)^{1/n}) =  \lim_{n\to\infty} (1/n)\ln(n!) =  \lim_{n\to\infty} (\ln(n!)/n)$$ Applying L'hopital's rule:  $$\lim_{n\to\infty} [n! (-\gamma + \sum(1/k))]/n! = \lim_{n\to\infty} (-\gamma + \sum(1/k))=  \lim_{n\to\infty} (-(\lim(\sum(1/k) - \ln(n)) + \sum(1/k))  = \lim_{n\to\infty} (\ln(n) + \sum(1/k)-\sum(1/k)  = \lim_{n\to\infty} (\ln(n))$$ I proceeded to expand the $\ln(n)$ out into Maclaurin form $$\lim_{n\to\infty} (n + (n^2/2)+...) = \infty$$ Since I $\ln$'ed in the beginning, I proceeded to e the infinity  $$= e^\infty  = \infty$$  So am I write in how I approached this or am I just not on the right track? I know it diverges, I was just wanted to try my best to explicitly show it. Travelling to Italy without my spouse who is a UK citizen I have an ArrayList&lt;String&gt;, and I want to remove repeated strings from it. How can I do this? Flag dialogue popup is stacked behind realtime-post-deleted-notification banners There is a little bug that becomes visible when a page contains realtime-post-deleted-notification banners (that's the CSS classname of these red banners appearing on answers which just got deleted, see screenshot below) and you try to open the flag dialogue above them:    Obviously, the dialogue appears below the banners, which it clearly should not do. It also has no input focus, trying to interact with the dialogue fails and either closes it (clicking outside of the red banners) or reloads the page (clicking on the red banners).  The cause for this is simply the z-index ordering in the site's CSS. Relevant CSS snippets:  .realtime-post-deleted-notification {     position: absolute;     text-align: center;     z-index: 100; }  .popup {     display: none;     padding: 15px;     position: absolute;     z-index: 10; }   So the fix for this minor bug would probably be to raise the z-index of the popup class to something greater than 100. Is it possible to produce a context free grammar for Tikz path? node? Even further, I would be happy to see a definition of the tikz language in the usual manner programming languages such as Java and Pascal are defined.   The reason I ask is that I keep getting mysterious error messages for the tiniest typos. Essentially, incorrect use of the underlying languages leads to a "crash" of the compiler. This crash sometimes gives useful error messages, but sometimes they are hard to decipher. I have a Multisite Wordpress installation with 7 different blogs. I want to show an aggregate of the summaries of posts from those 7 blogs in the main blog. Do you know a good way to do this? Suppose we have a ball floating in liquid A. Then we pour a liquid B on top of the ball (Assuming that the liquid is poured such that the ball doesn't oscillate) . The ball rises up. Why?  According to me, the liquid on top (liquid B) will exert a force downward on the ball and it should go lower. The particles in the liquid B will exert an normal force which is acting downwards on the ball. How can adding liquid B make it rise up, that is, provide an upward force?  Taking a specific case, density of B > density of ball > density of A   what would happen? Which shell am I running on? How to create svg symbols that have modifiable fill color, stroke color and stroke width? I want to create some svg symbols for Qgis using Inkscape, those symbols must have attributes as described in the question. For the last two days, I have been experimenting as instructed by  and mimicked some symbols came bundled with qgis that have desired attributes without any success.  Finally I experimented with the simplest form of symbol: I created an svg that contains only a circle in Inkscape and tried to modify it.  The original file () have this line:  &lt;path    sodipodi:type="arc"    style="fill:#ffffff;fill-opacity:1;stroke:#000000;stroke-width:1.01988637;stroke-miterlimit:4;stroke-opacity:1;stroke-dasharray:none"   I modified it into:  &lt;path    sodipodi:type="arc"    style="fill:param(fill) #ffffff;fill-opacity:1;stroke:param(outline) #000000;stroke-width:param(stroke-width) 1.01988637;stroke-miterlimit:4;stroke-opacity:1;stroke-dasharray:none"   Saved as  and selected it as point symbol, but Qgis couldn't change all three parameters at the same time.  What did I do wrong or should do differently?  My system: Qgis 1.8.0 on Ubuntu 12.04 64 bit, Inkscape 0.48, Gedit 3.4.1 text editor. Is it positive or negative for the average website to allow search engines to index user comments? I've been trying to answer this question myself by researching and searching on google but I haven't been able to come with a final answer. I have some hypothesis I would like share anyway:   The average website intends to reach the higher audience possible. User generated content by comments is an efficient way of increasing the relevance and the valuable information of the average website. Indexing comments will make any site attractive to spammers. Indexing comments is more convenient for new/low-traffic websites than it is for old/high-traffic websites. The web in general is currently choosing not to index comments in the average website because of fear to the SPAMMERS. The average author of a content-valuable comment would like his comment to be indexed Not indexing comments discourages the creation of content-valuable comments.   So, what do you think finally? Is it positive or negative for the average website to allow search engines to index user comments? Why? Faster Press and Hold Character Picker Does anyone know how to make the character picker appear more quickly?   I use it enough now in my German language studies that it has become second nature for the critical marks and much faster than using the alt+keypress shortcuts.   Only problem is that it's so second nature that sometimes it doesn't pop up quickly enough so I end up typing the character and the number shortcut sometimes (IE u2 instead of ü). Anyone know how to make it appear with less delay? Ideally, I'd love if I could just hold the character and press the number but it appears that OSX insists on waiting for the menu to pop up. update-java-alternatives vs update-alternatives --config java On Ubuntu 12.04 LTS I have installed Sun's JDK7, Eclipse, and the Arduino IDE. I want the Arduino to use OpenJDK 6 and want Eclipse to use Sun's JDK 7.   From my understanding I need to manually choose which Java to use before running each application. This led me to the update-java-alternatives -l command. When I run this I only see the following:   java-1.6.0-openjdk-amd64 1061 /usr/lib/jvm/java-1.6.0-openjdk-amd64   but when I run update-alternatives --config java I see the following:   *0  /usr/lib/jvm/java-6-openjdk-amd64/jre/bin/java   auto mode 1  /usr/lib/jvm/java-6-openjdk-amd64/jre/bin/java   manual mode 2  /usr/lib/jvm/jdk1.7.0/bin/java                   manual mode 3  /usr/lib/jvm/jre1.7.0/bin/java                   manual mode   I don't understand why the update-java-alternatives doesn't display the same 3 options. I also don't understand how to switch between OpenJDK6 and JDK7. How I can go about using the OpenJDK6 for Arduino development and Sun JDK7 for Eclipse/Android development? Is there a way to make the following return true?  string title = "ASTRINGTOTEST"; title.Contains("string");   There doesn't seem to be an overload that allows me to set the case sensitivity.. Currently I UPPERCASE them both, but that's just silly (by which I am referring to the  issues that come with up- and down casing).  UPDATE This question is ancient and since then I have realized I asked for a simple answer for a really vast and difficult topic if you care to investigate it fully. For most cases, in mono-lingual, English code bases  answer will suffice. I'm suspecting because most people coming here fall in this category this is the most popular answer.  answer however brings up the inherent problem that we can't compare text case insensitive until we know both texts are the same culture and we know  what that culture is. This is maybe a less popular answer, but I think it is more correct and that's why I marked it as such. I am curious how people picture geometrically how the covariant derivative acts with regards to vector fields. I understand that it is merely an object which has been defined for some use and obeys certain conditions but how would you picture such a thing geometrically? In other words, when someone asks you what the covariant derivative is, how do you explain it in absence of a formal definition? Is a switches voltage and current rating a hard limit? I am aware    but I ask this regarding SE-2.0 sites, as the example I will take gaming:  Both answers on the question  make perfect sense to me, i.e. on the one hand this might overuse the tagging system but on the other hand it would help a lot for filtering.  Therefore I suggest a system which, in this case, would internally store the platforms to which a tag is relevant and   if a question is tagged with one of these platforms, nothing special will happen and the question is to be considered platform specific (e.g. a bug which only appears on the PS3 version) if the question is not tagged with a platform, the only result will be that the tag filter mechanism works a bit different compared to what would happen if the question was (invisibly) tagged with all platform tags:   If the invisible tagging is definite on interesting or ignore (i.e. there is not at least one ignored and one interesting tag) the usual mechanism works. if the tagging is ambiguous (i.e. contains both interesting and ignored tags), no filtering happens at all    The actually attributed tags must of course override this behaviour. That way questions about a game one likes but which is available for a platform one doesn't care about will still be highlighted unless specifically tagged with that platform, but no additional tags have to be used to filter a game which is only available on ignored platforms.  This can of course easily be extended to other sites, e.g. the  may be interesting both general and for c++ but totally uninteresting if the question is only about a JavaScript implementation.  I am only unsure whether search should include those hidden tags, too. What are the current travel restrictions on individuals entering the United States from regions affected by Covid-19? This community wiki explains the current restrictions by the United States of America on the entry of individuals who may pose a risk of transmission of the SARS-Cov2, the virus which causes the Covid-19 disease. How to connect portable monitor USB Type-C to graphic card with display port or hdmi Suppose that $\hat{x}$ is the least squares solution of $Ax = b$.  That is, $\min{|r|}, r = Ax - b$ with respect to $x$.  Is $\hat{x}$ also the least squares solution of $JAx = Jb$?  I suspect so, but I'm not sure how to prove it.  If $J$ is invertible, it's easy enough to prove as you can just cancel it out from both sides.  But what if it's not invertible?
