I have a shapefile with 3800 polygons representing the smallest administrative areas in Ireland. Many of these, in rural areas, have tiny populations, under 100 people. In urban areas, all would have adequate populations.  For each area I have a population figure, and various other attributes, all of which can be intelligently summed to give valid results for areas produced by combining the smaller areas.  I need to merge the areas to get say, 500 or 600 areas of reasonable population. I need to leave the larger (in population) areas alone, where possible. I would greatly prefer to do this automatically. This is necessary for model fitting purposes, primarily.  I've looked at a number of the dissolve questions here:   'Batch Dissolve Polygons based on Attributes in QGIS or FWTools' I think would require me to know which areas to merge, when this is what I need to calculate. 'Practical way of managing polygons and unions of them' and 'How do dissolve polygons from shapefile using open source tools?' have the same issue.   Any suggestions? Fibonacci sequence and Euclidean algorithm's connection. Send urgent mail in Gmail Is it possible to set the "urgent" flag in Gmail for outgoing mail? I'd like to be able to flag time-sensitive emails as such. I read this book once when I was in middle school. A girl solves a murder or a mystery on a spaceship. It was a thin paperback books.   All I can remember is that there was an alien, and there was a movie star or actress or famous makeup artist on the ship traveling with another woman. By the end of the book the murderer was the woman the actress was traveling with who forced her to use her makeup skills to disguise her, and she was really some kind of alien.

Which one of the above sentences are incorrect and why? How to run sudo command with no password? How does the ubuntu user on the AWS images for Ubuntu Server 12.04 have passwordless sudo for all commands when there is no configuration for it in /etc/sudoers?  I'm using Ubuntu server 12.04 on Amazon. I want to add a new user that has the same behavior as the default Ubuntu user. Specifically I want passwordless sudo for this new user.   So I've added a new user and went to edit /etc/sudoers (using visudo of course). From reading that file it seemed like the default ubuntu user was getting it's passwordless sudo from being a member of the admin group. So I added my new user to that. Which didn't work. Then I tried adding the NOPASSWD directive to sudoers. Which also didn't work.   Anyway, now I'm just curious. How does the ubuntu user get passwordless privileges if they aren't defined in /etc/sudoers. What is the mechanism that allows this? Terminology of the sequences of promoters in relation to DNA strands I'm studying molecular biology and I'm trying to understand an experiment which shows the importance of promoters in the relative transcription level (RT). The image below comes from Rolf Knippers' book "Molekulare Genetik" (8th edition).    The legend says (among other things):     Die erste Zeile gibt die normale "Wildtyp"-Sequenz der 5'-flankierenden Region wieder.   Which, in english, means something like:     The first line repeats the normal wild-type sequence of the 5' flanking region.   The column on the right gives the relative transcription (RT) level, 1.0 being the highest possible level of transcription. As we can see, the lines where some parts of the "5' region" have been deleted give quite low RT levels, since some regions of the promoter are missing.  My questions are the following:  1) According to  and , I understand that RNA polymerase reads and uses both coding and non-coding strands in order to synthesize RNA. Therefore, how did they manage to use the sequences strands regions had been deleted to make a polymerase "read them" and perform transcription?  2) If the polymerase reads the template strand in the 3' -> 5' sense, shouldn't we talk of "ATAT box" or "TAAC box" instead of "TATA" or "CAAT" boxes? Does it mean that the "promoter" regions they are using on the graphic above are actually on the coding strand?  Thanks a lot for your help. How to add a custom action to the list ribbon?

This works fine; I can see and transfer files with Nautilus. However, I often want to use the terminal to move large numbers of files, and I cannot seem to find the device anywhere in the filesystem tree.

Can you catch a native exception in C# code? In C# code can you catch a native exception thrown from deep in some unmanaged library?

Prove that the convergence of $\sum{a_n}$ implies the convergence of $\sum{\sqrt {a_k} \over k}$ if $a_n \ge 0$.  Proof:  I will attempt to show that the cauchy criterion is met so $${\sum_{k=n}^m {\sqrt {a_k} \over k}} \le \epsilon $$ for all $n,m \le N_1$. Im disregarding the absolute value since its all positive terms.   Since $\sum{a_n}$ converges, we know that the $\lim \limits_{n \to \infty} a_n =0$ So there exists some $N_2$ such that for all $n \ge N_2$, $$   a_n \lt \ {{(m-n)}^2k^2(\epsilon)^2} $$ I am again disregarding the absolute values because its always positive Let N=max{$N_1,N_2$} then for all $n,m \ge N$ $$\sum_{k=n}^m {\sqrt {a_k} \over k} \le \sum_{k=n}^m {\sqrt {{(m-n)}^2k^2(\epsilon)^2} \over k} \le \sum_{k=n}^m{(m-n)(\epsilon)} = \epsilon $$  Maybe this is just crazy, should I just use Cauchy-Schwarz inequality and forget about this or could I possibly make this method work? I have the CKeditor plugin installed by itself (i.e. not using WYSIWYG module.) Then, it uses a CKEditor library located in sites/all/libraries/ckeditor. This works fine. I'd like to add more plugins to it; namely, the footnotes plugin. (For the moment, please refrain from "just download a new library from ckeditor.com and replace it"; there were other issues/considerations involved.)  Now, I see this everywhere when I try to look for a solution  config.extraPlugins = 'footnotes';   I tried adding that to admin/config/content/ckeditor/edit// -> Advanced Options -> Custom JavaScript configuration, but it white screens the editor.  I tried adding it to the config.js in sites/all/libraries/ckeditor like below, but it had no effect.  CKEDITOR.editorConfig = function( config ) {   config.extraPlugins = 'footnotes'; };   I can't really add it to a ckeditor.config.js file, dump that file in my theme, and choose "Yes" for "Load ckeditor.config.js from the theme path", since (for content creation/editing) it uses the admin theme which is different from the theme we're developing.  So, I'm at a loss. The only other thing I can think of is to use a hook in the module we have for the site, but I'm not sure if that's write/what hook would be called.  Is it just me, or does it seem like clear documentation on how to manage CKEditor in Drupal is severely lacking? Any help would be appreciated.  UPDATE: After some testing, it looks like the "Custom JavaScript configuration" is supposed to work, but it is possibly broken for CKEditor 4.4+ I read something (can't seem to find it now) that suggested the plugin/widget import was broken on 4.4+, so I changed to 4.3 and the extraPlugins worked. Now, I wasn't able to get footnotes working (which is what kicked this whole thing off), but some other plugins that previously failed during the same steps now work on 4.3. So, there's that. I'm wondering now if it's something with footnotes itself. How to make equally sized windows in corners of the screen? What is the term for a sentence which reads same forwards and backwards? Please note, I'm not asking for a palindrome.  I mean to say that only the word  order is rearranged, not the actual spelling of the word.  An example might be as follows:     First ladies rule the State and state the rule: ladies first. There has got to be the establishment of a universal auxiliary language.   Does the verb got add more to the context or is it there just for emphasis? Is it even grammatical?  Using Google-Ngrams I found a few similar versions as follow: . For example;   For many from the North, however, it has seemed difficult and there has seemed to be a problem. There has come to be a convolution between this become enmeshed concept of marriage as it exists in the sacred and how it exists in the secular. Most of the time since I have been here, there has appeared to be considerable feeling in the minds of a few. There has had to be some negotiation, obviously, but I think we provided what our soldiers need and what our country needs.   In general, I wanna know if 'have/has'+past-participle+'to be' is grammatical. How can you prove that the normal equations: $(X^TX)\beta = X^TY$ have one or more solutions without the assumption that X is invertible?  My only guess is that it has something to do with generalized inverse, but I am totally lost.
