Should I edit my deleted answer or add another answer?
I already have the "Edit Questions And Answers" privilege. Yet, if I approve someone else's edit, I'm told that more votes will be required before the edit is accepted.  This seems a bit peculiar to me, since I could just copy the edited version and paste it myself. Per line text gradient (ala beeline reader) What does 2>/dev/null mean? I would like a brief explanation of the following command line:  grep -i 'abc' content 2&gt;/dev/null Do you have advantage when multiple sources give advantage and only one gives disadvantage? As I understand it:   if you have Advantage from two different sources, you simply have Advantage (no stacking) if you have advantage from one source, and disadvantage from one source, they cancel out.     So what if you have advantage from two or more sources, and disadvantage from one source?  My assumption is that you simply have advantage, or put another way, you have Advantage on a roll when the # of Advantages > # of Disadvantages (and vice versa).  Is that correct?

I only have access to the server via a terminal and I can't use graphical tools such as GParted! I want to create a new partition from a part of the root (about 768mb) for swap.  # df -h Filesystem      Size  Used Avail Use% Mounted on /dev/vda         20G  1.3G   18G   7% / udev             10M     0   10M   0% /dev tmpfs           199M  4.9M  194M   3% /run tmpfs           100M   12K  100M   1% /run/user tmpfs           5.0M  4.0K  5.0M   1% /run/lock I just watched a TV show and the guy says:     I ain't trying to fight with nobody with a baby.   So here, I can't understand the "nobody" since it make no sense to me, but it sounds like anybody, and if it's "I ain't trying to fight with anybody with a baby." that makes sense to me. Does the PHB+1 character-building limit in Adventurers League include spells? I’m thinking of trying out a Hexblade Warlock in Adventurers League, which limits players to PHB+1 for character-building.  The problem I have with this is that the Hexblade is from Xanathar's Guide to Everything, but I really want the booming blade cantrip as well from the Sword Coast Adventurer's Guide. Is this legal in Adventurers League play? Someone has asked for answer to these topics. However, I still want someone to provide me with simple and universal answers. I recently read a sentence from the English-speaking person. It is in an article. It is, ' The available options for mitigating pad cratering are not universally effective (see link below), but they may be helpful on a case by case basis until more crack resistant laminates are developed and become available.  '  If I am to write this, I will use 'a case-by-case basis until more crack-resistant laminates'   Can anyone tell me when to use a hyphen to coin a new word? "exec: gnome-session: not found" when logging in using lightdm On login the password is accepted but I'm returned to the login screen. Tried multiple times even after reboot... same behavior.  I left my laptop (Lenovo Ideapad z510) in suspend mode (lid down) last night, but it did not resume this morning, as it usually does. It had shutdown or crashed, and on booting with Ubuntu the login failure mentioned above started.  cat ~/.xsession-errors /usr/sbin/lightdm-session: 1: /usr/sbin/lightdm-session: ls: not found /usr/sbin/lightdm-session: 104: exec: gnome-session: not found   Okay. I've tried a bunch of suggestions from    Changed id to /usr/sbin/id in /etc/profile removed .Xauthority removed /tmp removed,  purged and re-installed lightdm checked .profile for syntax errors (source .profile worked fine, so I guess no syntax errors)   Nothing worked. My guest login is working fine, so another user should also work. I'm now going to create another user and continue working, but a solution to this problem is still warranted... it's likely going to repeat in future.  Installing and reconfiguring gdm also did not work.  sudo apt-get install gdm Using \vfill between two texts works:  \newpage bla \vfill blabla   but it doesn't work if there is no text before it:  \newpage \vfill blabla   How can this be achieved? I've been using gksudo nautilus and sudo nautilus through Alt+F2.   What's the difference? They look very similar! Intuition of the meaning of homology groups Ubuntu16.04 boots into initramfs Ubuntu doesn't boot up and it goes into initramfs. I am writing from a live CD trial session. what should I do?  I understand that the boot flow is broken and that when the files from root are going to be loaded into the ram, it does not find the files in the root directory. Please correct me if I'm wrong.  The following is the output from ashell as I input the "exit" command:  (initramfs) exit /dev/mapper/ubuntu--vg-root contains a file system with errors, check forced. Inodes that were part of a corrupted orphan linked list found.  /dev/mapper/ubuntu-vg-root: UNEXPECTED INCONSISTENCY; Run fsck MANUALLY.     (i.e., without -a or -p options)  fsck exited with status code 4. The root file system on /dev/mapper/ubuntu--vg-root requires manual fsck Is it possible to make a simple query to count how many records I have in a determined period of time like a year, month, or day, having a TIMESTAMP field, like:   SELECT COUNT(id) FROM stats WHERE record_date.YEAR = 2009 GROUP BY record_date.YEAR   Or even:  SELECT COUNT(id) FROM stats GROUP BY record_date.YEAR, record_date.MONTH   To have a monthly statistic.

Circuit tester trips new GFCI I replaced a non-protected receptacle with a GFCI type and now my circuit tester trips the GFCI as soon as it is plugged in.  The receptacle tested fine before replacement, ground, neutral, hot, etc.  I've double checked the hot/neutral/ground connections.  I've also tried it with the downstream load disconnected.   The GFCI trips the moment I plug in my circuit tester (before pushing the test button).  Otherwise things check out OK.  I can plug in a power tool without it tripping.  Also, the integrated test/reset button work correctly.   I've read that the integrated test button is the only one that truly matters. Is this correct or should I be concerned? I'm sure a home inspector will red flag this if their tester has the same result.  Update  My tester is by "Commercial Electric".  The tester is one of the palm sized three prong type with three leds to indicate the condition of the circuit and a button on top to test GFCI. It's new from the local box store. Calculate expected values using logistic regression coefficients The outcome of the logistic model is binary (0;1) - intervention that occurs in hospital (3838 interventions in 51096 cases). I am modeling the effect of age groups (60 to 74; 75 to 89 and 90+) and sex (female) on the outcome. My reference age group is male aged 18-59.  My logistic regression coefficients look like this:  intercept  -4.313 female      0.5117 age 60-74   0.4081 age 75-89   1.1761 age 90+     1.5612.   Corresponding odds ratios:  female      1.668 years60_74  1.504 years75_90  3.242 years90     4.764   Now I am trying to obtain a probability of an outcome = 1 for each case.
