Like on for example a header, would having only icons be confusing for the user, or would having words and icons take up too much space? I think that the icon only design is really clean, but don't know if the users would know what the icons mean.  Here is an example of what I am talking about
Are there any rules on when to use icons vs. icons with text vs. just text links in a web application?  For example:    vs.   save  vs.  save    Extra question: Is  save -or- save  preferable?
When to pronounce ‹s› as /z/ in the middle of words? Center text in color box I wanto to center a text in a colorbox which is scaled horicontal over the complete site.    How is this possible?  \documentclass[ ]{scrreprt}  \usepackage[ ]{scrpage2}  \usepackage[ngerman]{babel}                 %% Deutsches Sprachpaket \usepackage[utf8]{inputenc}                 %% Eingabezeichensatz UTF-8 \usepackage[T1]{fontenc}                    %% Kodierung für Umlaute \usepackage[ngerman]{translator}            %% Für Abkürzungsverzeichnis benötigt \usepackage{lmodern}                        %% Moderne Version von Computer Modern \usepackage{setspace}                       %% Zeileabstand anpassen \usepackage{xcolor}                         %% Definieren von Farben  \begin{document}  \chapter{} \definecolor{lightgray}{gray}{0.5} \newcommand \colbox [1]{\par\noindent\colorbox{gray}{\begin{minipage}{\textwidth}{ {#1}} \hfill \end{minipage}}}  \colbox{TEXT}  \end{document}   Moreover I want to avoid the overfull hbox. I have seen a few  here on Meta&nbsp;Stack&nbsp;Exchange that cover parts of this, but they are often too local, and none of them seem to cover all the relevant scenarios.  I will break it up into multiple parts in order to make this more specific:     When should I vote on a question:   What are the qualifications for a question to be deserving of being up-voted? When shouldn't I vote up on a question? What are the things that would cause a question to need to be down-voted?   How should I go about down-voting the question (do I wait a little while to give the OP a chance to change it, or do I down-vote it immediately)?  When shouldn't I vote down on a question?  When should I vote on an answer:   What are the qualifications for an answer to be deserving of being up-voted? When shouldn't I vote up on an answer? What are the thing that would cause an answer to need to be down-voted?   How should I go about down-voting the answer (do I wait a little while to give the OP a chance to change it, or do I down-vote it immediately)?  When shouldn't I vote down on an answer?  When should I vote on a comment:   While votes on comments do not affect reputation points, it might be useful to new users to know when to up-vote them.    It seems that a full, comprehensive list of these would be invaluable to new users looking to figure out how the voting system works, but this list seems to be missing from the meta site. Can I request the code behind a research paper from the author? Is there any parameter (in terms of physical quantities such as mass, length, charge...) which can be used to decide when to treat a system quantum mechanically and not classically? Does an Enlarge/Reduce spell on a druid affect the beast form if the druid Wild-Shapes? If a druid (multiclassed into sorcerer) casts Enlarge on himself so that he becomes a Large humanoid (approximately twelve feet tall), and he then Wild Shapes in a brown bear, is the brown bear form normal size or doubled in all dimensions? Number of ways to stack poker chips if two stacks that can be obtained from each other by reflection are considered to be equivalent? How to fill in the Schengen visa application form when going to several countries? I will be traveling to France, Italy and Germany with France being my main destination. So I am applying in the French consulate for Schengen visa. I will be traveling on my own and will be staying in hotels.  I had some doubts with regards to filling the application form for Schengen visa.    Q22- Member State(s) of destination: Should I fill in all three of my destinations ? Q31 Surname and first name of the inviting person(s) in the Member State(s). If not applicable, name of the hotel(s) or temporary accommodation(s) in the Member State(s) : This field has barely a line of space to enter. Should I just enter the hotel name in France (my main destination) ?  Q32 Surname and first name of the inviting person(s) in the Member State(s). If not applicable, name of the hotel(s) or temporary accommodation(s) in the Member State(s): Same problem as Q31. Very little space. Should I just enter address of the one hotel I entered in earlier Q ? Backquote in lsblk output What does ` mean in this output from lsblk? Prove by induction that $(x+1)^n - nx - 1$ is divisible by $x^2$ Basis step has already been completed. I've started off with the inductive step as just $n=k+1$, trying to involve $f(k)$ into it so that the left over parts can be deducible to be divisible by $x^2$ but getting stuck on this inductive step. Is there any software or hardware which lets you stop, slow down, speed up or even reverse time? Obviously I'm talking about time in terms of the PC clock rather than real time.  We were testing an application we've developed at work by setting the clock forward and back to simulate different scenarios and I started thinking how useful it would be if you could adjust the rate(?) of the system clock with finer control. So you could make a minute pass in a second or a day pass in 30 seconds and watch how the program you're developing copes with changes in date and time.  Is there any such software available?   I'd be interested to hear if anyone knows of any software or hardware which can let you do some or all of the above. If a spell is cast on a moveable creature/object and lasts longer than a round, and the creature/object moves, does the spell move with it? Rank of a Matrix Sum I have $3\times3$ matrices such that S=A+B. I know there is an inequality connecting rank of the matrices A, B and its sum S. Could you write down that here? It will be a great help for me.  Means equation  or inequality connecting rank(S), rank(A) and rank(B). Dealing with non-integral powers on negative numbers If we are given an expression $(-8)^\frac26$, how do we solve it?  If it is $(-8)^\frac13$, we can find the cube root of -8 which is -2. However, if we square it first and find the sixth root, we get +2 (or maybe $\pm2$, which still isn't the same as just -2.  Also realised that when solving logarithmic and exponential questions, I had often made the assumption that if $b^a=b^c$, then $a=c$, either explicitly, or via some formula. I don't know if this is really true now.  So is there some convention by which we solve non-integral powers or is it just undefined to do so or something?  P.s. Talking of non-integral powers, will a quantity like $(-8)^{√3}$, will it be positive or negative. (Basically that's an irrational power now.) What books, journals, and/or electronic resources have you found most valuable for expanding your knowledge in the GIS field, and why? How to revert to GNOME Classic Desktop? What if a light clock travels perpendicular to mirrors that make up the clock? Is there a cleaner proof of convergence for this almost-telescoping series I was wondering how the convergence of the series $$\sum_{k\geq1}\frac{(k+1)^y-k^y}{k^x},$$ depends on $x$ and $y$, where $x$ and $y$ are real numbers. I've been able to show that it converges if and only if $y\leq x$, by distinguishing nine cases; whether $x$ and $x-y$ are positive, negative or zero. If desired I can include a sketch of my proof. My question is whether there is a proof that works for all real $x$ and $y$? Or at least a proof that seems less artificial? How do I sudo a command in a script without being asked for a password? Does a logistic regression maximizing likelihood necessarily also maximize AUC over linear models?
