Command for forcing a pointer ungrab (captured mouse release) Sometimes Firefox doesn't release the mouse after dragging, so I need to kill the application to force it to release its pointer grab.  Is there any command to force an application to ungrab the pointer without killing it? After doing a "sudo su -" on an Ubuntu 12.04 notebook I did a "crontab -e", added this:   * * * * * env DISPLAY=:0.0 /usr/bin/gnome-calculator   and waited for minutes. Nothing Happened. I don't have any external monitors and if I run this command "env DISPLAY=:0.0 /usr/bin/gnome-calculator" in the terminal, it just works. But not from cron. Why?   The syslog only contains this:   May 24 14:37:01 localhost cron[1227]: (root) RELOAD (crontabs/root) May 24 14:37:01 localhost CRON[16432]: (root) CMD (env DISPLAY=:0.0 /usr/bin/gnome-calculator )   And I already tried an "xhost +localhost".   [root@NOTEBOOK /var/log] xhost access control enabled, only authorized clients can connect INET:localhost.localdomain SI:localuser:USERNAME [root@NOTEBOOK /var/log]    So the solution for another question like this on askubunut didn't worked. I  and am I sometimes find myself writing something like this:     XXX is a project I admire and am very interested in.   The "I &#60;verb> and am &#60;something>" feels strange here. It somehow sounds more natural in the third person: "He admires and is very interested in...."  Am I just imagining things – is it OK to use this construction, or should I use something completely different? Do WALLS matter if I'm building the 6-inch brick defense from Corruption/Crimson for my city? I think everybody with a history of participation can't help but notice the explosive growth of repeated duplicate questions. The work of looking for duplicates and then closing questions has overtaken the work of actually answering questions.  It's become virtually impossible to ask something which hasn't been yet asked. Lately I feel boredom each time I see a new question and start answering it only to realize after the first written sentence that I have answered similar questions five times over or seen them answered some ten times or more. I know where it's going to be going and what answers with what votes it is going to receive before any answer is even written.  It's obviously not the administration's fault, it is simply so. The questions is, what to do about it? Engaging more moderators to close and close duplicates won't work because it's already starting to repel users who get mad at their questions closed and become afraid of asking more or perhaps just go away.  The original idea of Jeff stated the the site is for questions that can be answered. Meaning no open-ended discussions. When I first read this I had a casual thought - well, and what's gonna happen when they all are asked and answered? Will it become a museum, a monument of wisdom and knowledge or what?  I'm not sure what to do about it. Perhaps deprecation/versioning of older questions so that their new versions can sparkle the tiresome evening...  POSTSCRIPTUM.  I recall Star Trek Voyager episode  when another Q asked Captain Janeway for asylum. He was tired of immortality and wanted to die. They opened a hearing and went on to visit the continuum to evaluate the living conditions there which caused the suffering and the wish to escape it in death. A lifeless picture presented itself to the visitors... a house lone in an open space, two people going about their business, nobody talking. When asked why they were silent, the following was said. It's been so long, all has already been said, all stories told, all jokes are made... there is nothing left to do...  Are we there as well?  UPDATE: Just saw this answer in another question:       Also, some of the core questions got asked early on in the life of the site. Great questions still come around from time to time, but many have already been asked.   Doesn't that confirm my point? Need to develop a tapered spacer for under a car lift on an angled concrete slab I need to fabricate/develop an angled spacer.  13 inch wide by 10 inch long, by 3/4 inch to 1 3/8 inch thick. This spacer is needed to go under two of the posts of a hobbyist car lift in my garage. The garage floor is angled by the door where two of the four corner posts will go. These two rear posts need to be on a flat surface and at the same level as the two front posts.  Each post pad will need to handle approximately 2000 pounds. I was thinking of building a 4-sided mold where the column pads would be on the angled concrete and pouring some type of epoxy, resin, or cement into the mold. Which the metal plate from car lift posts would sit on. enter image description here Hyperlinks to web sites using anchors sometimes don't work This is meant to solve this problem once and for all. What is every reason an object isn't showing up in a render or viewport in when using the cycles render engine? We have this large database (>1TB) that we intend to "shrink".  The database revolves around one main entity, let's call it "Visit".  For discussion, let's say it is a database for a medical practice.  There are a total of 30 visit "types", such as procedure, annual, follow-up, immunisation etc, each of which is a subsidary table to "Visit", e.g. "visit_immuno".  The database has accummulated some 12 years of data since 2000.  Someone has proposed that we keep about 3 years of data in the "live" version and have the rest live in an "old_data" database.  The date is ONLY stored in the "Visit" table since it is normalised.  The Visit table also contains a ROWVERSION column and a BIGINT pseudo-identity (clustered) column.  For all intents and purposes, let's say the clustering key is populated by a SEQUENCE (SQL Server 2012 Enterprise) - we shall name it cid.  The visit.date is not always in the same order as the clustering key, for example when a doctor goes on extended visitations and returns with his "briefcase" of data, it gets merged into the main table.  There are also some updates to the "visit" table that will cause the ROWVERSION column to be out of sync with both the cid and date columns - to put it simply, neither ROWVERSION nor cid would make suitable partition keys for this reason.  The business rule for removing data from the "live" is that the visit.date must be greater than 36 months and a child visit_payment record must exist.  Also, the "old_data" database does not contain any of the base tables except visit%.  So we end up with:  Live DB (daily use) - All tables Old-Data DB - older data for the visit% tables  The proposal calls for a Combined DB that is a shell containing Synonyms to ALL the base tables in the Live DB (except visit%) plus Views that UNION ALL across the visit% tables in the two databases.  Assuming the same indexes are created in the Old-Data DB, will the queries perform well on the UNION-ALL Views?  What type of query patterns might trip up the execution plan for the UNION-ALL Views? I need to do an  request in JavaScript. What's the best way to do that?  I need to do this in a Mac OS X dashcode widget. Removed Python 3 and now Ubuntu Software Center, terminal and other applications don't work I am a new Ubuntu user running Ubuntu 13.04.  I've been trying to install and use a DeDRM tool, but I've been having problems doing so. I was following some directions that said I needed a version of Python 2.7, but not anything Python 3.0 or later (because 3.0 versions are missing some necessary libraries?). I tried to install Python 2.7.5.6, but it didn't work. I thought it was probably because I had the later version of Python, so I went through terminal and removed Python 3.3, so I could install the earlier version of Python.  Now that I've uninstalled Python 3.3, a lot of applications no longer work, including the terminal and the Ubuntu Software Center. I have no idea how to fix this problem now. What is the Big-O time complexity of the following nested loops: for (int i = 0; i &lt; N; i++) {     for (int j = i + 1; j &lt; N; j++) {         System.out.println(&quot;i = &quot; + i + &quot; j = &quot; + j);     } }  Would it be O(N^2) still?

How to prove $\lim \limits_{n\to\infty}(n+1)\int_{0}^{1}x^nf(x)dx=f(1)$ I need help to prove this in real analysis. I think it uses IMVT, but not sure how to do it.

Make font size bigger than max limit of 1296 pt in Adobe Illustrator (2015)? For some reason and for many years there's a limit for font size in Illustrator. It is 1296 points max, so you can't go bigger without converting type to outlines first. Converting to outlines means you will not be able to edit type parameters and text it-self. Don't know how about you, but this makes me sad in non-destructive editing era.  What's your workaround? How to get cross-references to multiple figures? Mboxcox, interpreting difficult regressions Mboxcox in Stata suggests transforming my variables using a power of 0.1 for the independent variable, and 0.4 for the dependent variable.  I have run the model, and it fixes problems associated with the assumptions of OLS. But certainly, it complicates matters in terms of interpretations.  Please outline possible interpretations and solutions.  Dependent variable is in millions of dollars, and independent variables are number of years.  and a number of dummies which do not require transformation.
