I want to download my data from QGIS to an existing table in Postgresql. I tried to use DB Manager, but the field add to existing table doesn't work. Maybe somebody knows what the problem is?  Or is there another way to solve the problem?
I want to append some data to a layer in my PostGIS DB using a shapefile, but when I use the Import layer/file tool in QGIS, it doesn't allow me to choose the append option.  Why is this and how do I get it to allow me to append?
reconfiguration issues with dpkg I ran into some problems installing a package with apt. The terminal hung up during an install and I saw no other choice but to close the terminal. The problem, however, is that I can't seem to solve the issues that this has caused.   As is typical, I get:  E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable) E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?   This gets me nowhere and I'm locked out until I run sudo dpkg --configure -a. Makes sense. However, this process spits the following out and then hangs on the last line:  Setting up virtualbox-dkms (5.2.10-dfsg-6) ... Removing old virtualbox-5.2.10 DKMS files...  -------- Uninstall Beginning -------- Module:  virtualbox Version: 5.2.10 Kernel:  4.15.0-23-generic (x86_64) -------------------------------------  Status: This module version was INACTIVE for this kernel. depmod...

When I try to fix the broken packages (sudo apt install -f), the system also hangs on the same line, although the output is different:  Reading package lists...

Loading new virtualbox-5.2.10 DKMS files... Building for 4.15.0-23-generic Building initial module for 4.15.0-23-generic   I am unable to get out of it unless I kill the process. This I do by checking what is currently running related to apt (ps aux |grep apt), and then I kill the relevant processes with sudo kill -9 process_number_here.  If I try to run things after that, it tells me I still need to reconfigure dpkg.  I tried looking around for more solutions to dpkg and all I really see is the nuclear option:  sudo rm /var/lib/dpkg/lock sudo rm /var/cache/apt/archives/lock sudo rm /var/lib/apt/lists/lock   I also delete the files in /var/lib/dpkg/updates because when I did some digging one of the files inside had the exact same text as the above long output... but I fully admit to being out of my league here and I don't know what to do.   Taking a look at the error messages, I recognize that it hangs on building something related to the kernel. But I have no idea where to even start solving that. Any help is appreciated. My system is ubuntu 18.04 Evaluate the sum: $\sum\limits_{n=0}^{\infty} \frac1{F_{(2^n)}}$ Evaluate the sum:  $$\sum_{n=0}^{\infty} \frac{1}{F_{(2^n)}}$$  where $F_{m}$ is the $m$-th term of the Fibonacci sequence. I need some support here. Thanks. Many spells have "At higher levels" that provides for more targets or more damage.  For example Magic Missile can be cast as a second level spell and shoot 4 missiles instead of it's 3 as a first level spell.  Can a spell without that verbiage, such as Firestorm be cast in higher level slots for the same effect as the lower level spell? What is the difference between "I am done" and "I am through"? How does new shield system work? After the upgrade I can't figure out how the new shield system works. I have the option to discard the shield, and I notice I have a new potion in the inventory.  More importantly, I got attacked (and lost) twice in a short amount of time and don't have a shield. When do you now get shield? 8 bits representing the number 7 look like this:  00000111   Three bits are set.     What are algorithms to determine the number of set bits in a 32-bit integer? Prove that if $V$ is an inner product space, then $|\langle x,y\rangle| = \Vert x \Vert\Vert y\Vert$ if and only if one of the vectors $x$ or $y$ is a multiple of the other.  I am given a hint to let $a= \frac{\langle x,y\rangle}{\|y\|^2}$, and let $z = x - ay$, then prove $y$ and $z$ are orthogonal and $|a|= \frac{\|x\|}{\|y\|}$. I don't know how they come up with this, what was the original idea? Javascript function only works if there's an alert [Probability]need help to understand the following expression So assume $Y$ and $X$ are exponentially distributed with parameters $y_1$, and $x_1$ respecitively.  assume c is a constant.  I am having huge trouble to understand the integration of the following expression.  $P(Y&lt;c/u(X))$  $=\int_{t}^{\infty}f_X(x)\int_{0}^{c/u(x)}f_Y(y)dydx +\int_{0}^{t}f_X(x)\int_{c/u(x)}^{\infty}f_Y(y)dydx$  where t is the cross-point that $u(x)$ change sign    here $c/u(x)$ is given by the plot below, t is the point crossing the zero:   Confusion:   I don't understand the second integration of the second term "$\int_{c/u(x)}^{\infty}f_Y(y)dydx$", this isn't right because Y an X only defined for y>0, and x>0. So it's the first quadrant in this plot. According to the microtype manual, Kerning, Spacing and Tracking are not enabled by default in pdftex (>= 1.4). What are the reasons for this?

I am looking for a word that would describe being obsessed with the details of a larger entity such that the "looker" neglects to see the whole or (perhaps more importantly) the purpose of the whole.  Basically, "not seeing the big picture".  What can [more] succinctly describe this?  Edit: I just found this post: . I think I want the exact opposite. I never had this problem until today. When I watch a youtube video everything is fine, until I make the video fullscreen. It actually continues to play perfectly when fullscreen, but when I then exit fullscreen my sidebar and topbar are gone, and the screen is just frozen. Also my cursor is gone. It does seem to respond to ALT-F4, but it takes about 15 seconds to even close the window, and after that everything is unusable (basically frozen). What's strange though, when I re-enter fullscreen after exiting (and unity being frozen) the video plays perfectly still.   For now my workaround is opening tty1 and executing pkill -u username which logs off the user. I have looked at /var/log/syslog but it seems to be empty.  Is this freezing a common problem, if not, how can I make steps to fix this?

EDIT 3: Reinstalling chrome didn't help. Will try chrome 32-bit too now... Why are these numbers not equal?

How about having a badge "Irritable" for a user who downvotes over 20 times in a month and then have maybe further "Furious" for over 50 downvotes in a month....just a fun suggestion...since i see people downvote like crazy at times...there should also be a way to downvote a comment i think in addition...
