I want to access PC in LAN from other devices. I cannot use static ip for my PC. Is there a way to use hostname instead of dynamic ip to access PC so that even if ip changes i can access PC with its hostname? I am usin Linux.
I'm new to Linux (currently running Ubuntu 10.04) and I have just finished setting up SSH access to my Linux Machine.  Currently, I have to use ssh root@x.x.x.x to connect but would much rather be able to swap the IP for the computer name (like in Windows with \\name) or a domain name (like computername.example.com). I don't really know where to start so any help would be most appreciated.  Please go slowly, as mentioned - I am still new to this.  EDIT 1 Completely forgot to mention that I am trying to connect from Windows 7 (via PuTTY) - sorry.
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? Why can't variable names start with numbers? What is the definition of how to count degrees of freedom? resulted, rather as by-product, the discussion on how to count degrees of freedom (DOF). I extend that question here:   Are necessary1 derivatives such as velocities counted as individual DOFs or together with the respective coordinate2? Should complex valued DOFs be counted twice as in "two real-valued DOFs" or once as in "one complex-valued DOF"? (I mean, when one does not want to specify this explicitly)   Please answer with some reference, unless it turns out this is actually a matter of taste rather than a strictly defined thing.    1) I mean those a value of which is required as an initial condition 2) I count fields in QFT as coordinates as well, while space-time-coordinates are parameters to me, if that matters. I know a field actually has $\infty$ (or rather, $2^\aleph$) DOFs itself, but let's say e.g. "one $\mathbb R^3$ continous DOF" in that case Can an irrational number raised to an irrational power be rational?  If it can be rational, how can one prove it? Why does an unhinged body rotate about its centre of mass? Product of square of distances from vertices of a polygon of radius a I want to find out the following product.  $\prod_0^{n-1}  (r^2 + a^2 -2ra\cos(2k\pi/n - \theta))$ I have been trying to use complex numbers but did not work out. The book I am reading the result is directly stated as $r^{2n} + a^{2n} -2r^na^n\cos(\theta)$. Please help. Why was William Cage sent to the base? Confused About Trigonometric Substitution A general question asked from time to time on stack exchange is question of trigger bulkification.  Therefore I have 2 questions:   Which best practices are you using? What is the best way to handle updates of more than 200 records? (In case of more than 200 records the trigger is executed more than once.) Find files that a user can write, efficiently with minimal process creation I am root. I would like to know whether a non-root user has write access to some files - thousands of them. How to do it efficiently while avoiding process creation? Why are there two tensions on my free body diagram? A man sits on a platform attached to a pulley and pulls himself up as shown (ignore the angle of the rope - it should be vertical). Apparently, the man/platform object has a force of 2T pulling it up. Why is it not just T?  Much appreciated! Writing comments in QGIS Graphical Modeler I want to explain my model step by step so anyone can easely understand what's going on.

How does one edit the 'postgresql.conf' file with the pgAdmin app?  With pgAdmin 1.18.1 on Postgres 9.3.x, when I choose File > Open postgresql.conf I get a file picker dialog. And, yes, I'm connected in pgAdmin as the superuser 'postgres'.  I know I've done this in older versions of Postgres. Simultaneously merge multiple data.frames in a list How to figure if it is safe to travel to the area I am interested in? When planning a trip, I like to make sure I will feel safe enough (I am talking about war/terrorism risk, not pickpockets), or at least I like to have an idea about the risks. I know the risk could be subject to political views (for example the political stability of a region might not be acknowledged by every country) and therefore I am mostly interested in a Western country view.  In order to figure that, I thought about checking travel operators offers. I suppose if they do not organise trips to a specific region, it might be due to political instability risks. But it might be due to a lack of tourist interest too. As I tend to travel without their help, I am not really considering this kind of source as very helpful.  So I am interested in one (or two, for cross-checking) source(s) of information with a western view (I mean I understand the view could be biased) regarding the security of ideally any area in the world. My expectation is that, the same way I can browse a tour operator's catalog of visited areas, I could browse through the areas and see if it is recommended or not to travel there. Evenly spaced menu items on Toolbar Conjugation: Do we cite authors or papers? When referencing to another work in a scientific paper, do we cite the paper or its author(s)?  This question is intended to clarify the conjugation of the verb that follows the reference -- especially in these cases:   One author, two papers:     Jane Doe (2015a, 2015b) list-s the very specific conditions under which...   -> lists (singular: referencing to Jane Doe) or list (plural: referencing to both papers) Several authors, one paper:     John Doe, et al. (2015) claim-s this and that.   -> claim (plural: referencing to the multiple authors of the paper) or claims (singular: referencing to the single paper). How to evaluate $ \lim_{(x,y)\to(0,0)}\frac{y^2\sin^2x}{x^4+y^4} $ Is the graviton hypothetical? Wikipedia lists the  as a hypothetical particle. I wonder whether graviton is indeed hypothetical or does its existence directly follow from modern physics? Does observation of gravitational waves amount to the discovery of graviton or could there be gravitational waves not composed of gravitons?
