I'd love to delete the Snap folder in my home. It takes 97 GB of space. No package manager should be allowed this amount of space in the /home mount point!  How can I safely delete Snap and all its content (without breaking dependencies)?  I am really not interested in hiding or moving the Snap folder. I wish to delete it and remove the package that is responsible for it. Really I was happy enough with aptitude.
I'm not particularly fond of apps cluttering my $HOME directory with their own files or directories. It's rarely a problem, because most apps have the courtesy to hide their data by prefixing it with a dot or conforming to the ~/.config standard. But not snap.  Q1: Have I misunderstood this directory?  Is ~/snap really a directory which I'm supposed to enter and access on a daily basis on a par with ~/downloads, ~/pictures, ~/work, etc?  Q2: In any case: Can I move it e.g. ~/.snap?  I can't find anything like /etc/snap, /etc/default/snap, or ~/.config/snap to tweak things. I tried export SNAP_USER_DATA=$HOME/.snap but it didn't work.
What is the Physical Meaning of Commutation of Two Operators? If $a,b,c$ are positive real numbers, not all equal, prove that  $$\dfrac{bc}{b+c}+\dfrac{ca}{c+a}+\dfrac{ab}{a+b}&lt;\dfrac{a+b+c}{2}$$  Progress: $\frac{bc}{b+c}-\frac{b+c}{2}=$ In Cycles, is there a way to create a procedural texture that follows the longitudinal lines of a sphere? Like a beach ball or globe? The texture should be able to be mapped to any sphere-shaped object, not just perfect spheres.    My current approach is to use a rotated wave texture, but that doesn't come from the poles (It uses latitudes) Ratio test and the Root test What is the simplest way to prove the Earth is round? Assume you've come in contact with a tribe of people cut off from the rest of the world, or you've gone back in time several thousand years, or (more likely) you've got a numbskull cousin.  How would you prove that the Earth is, in fact, round? Many programs needs folder names that starts with a dot, like .emacs.d, .gimp-2.2, .jedit etc. How do I create such a folder?  When using the Windows Explorer in Windows 2000 (and other versions), I get an error message saying "You have to enter a filename". The only solution I have come up with, is to open a command prompt (Start > Run > "CMD" > OK) and enter mkdir .mydir.  Why have Microsoft this error message in the Explorer, but not in the command shell? Is there any registry hack out there to fix this, so that I am able to enter the folder name directly in the Explorer?

"inputenc Error: Unicode char \u8" error while trying to write a degree symbol (invisible character) No matter how I try to do it I always get the following error :      !

Jenkins + git: "tell me who you are" error, why does it need to tag? Arguments for/against same birthday for siblings? My son is born on October 1st three years ago. My wife is pregnant again and the calculated delivery date is October 22nd. Both children are boys, 3 years apart. We might end in a situation where the delivery is earlier, for reasons irrelevant to this question.   I believe that around their birthdays is the only time in the whole year that the actual date matters. It really does boil down to practical considerations around patience (gifts) and planning. I think that if there is, say, a week or more between the birthdays then it's easy to separate but if the difference is only a very few days then it gets complicated, and that's the situation I'd like to avoid.  I know from friends that having the same birthday makes events easier to plan, from the parents' perspective. It would also remove the unhappiness of a small child saying "why does he get presents today and I don't." Being a twin, and married to one, I know that there's nothing problematic in sharing a birthday as long as both get their fair share of attention.    What are practical arguments for, and against, choosing the same birthday for the second child? What considerations apply when the second child's birthday is only a very few days after the elder sibling's? How can I make a bluish "white" LED less blue? Effective Refractive Index in Paper I am reading the paper, entitled "Artificial uniaxial and biaxial dielectrics with use of two-dimensional subwavelength binary gratings" by Eric B. Grann, M. G. Moharam, and Drew A. Pommet.   In the paper they mention this formula:        Do you know how it can be derived and where it comes from ? Find the nilpotents in $\mathbb{Z}_3[x]/(x^2-1)$ My company has recently exceeded our data storage cap (at 102% right now.. :/ ).  A large portion of the data that pushed us over our limit was due to an import of records.  The weird thing about this is that the records only had a couple of fields populated each out of the 200 total fields on the object.  What this tells me is that SalesForce holds the space for each field (since it knows the max-length of each field) rather than populating space only when the field is not null.  Does anyone know if this is the case?  To reiterate, and perhaps present this question more clearly:  If a field has a max character count of 1,000 and only 250 of those characters are actually being used, does SalesForce count the total data storage consumed by that field as 250 or 1,000? Unable to use built in events (Event Reference) Salesforce has functions that do a lot of basic web app functionality for you, called Event Reference. They can be found here   On the editRecord Event Reference, found here   essentaily, I create a   &lt;ui:button label="Edit" press="{!c.editRecord}"/&gt;   on my component, reference the attribute on the page and add the function from the docs in the controller  editRecord : function(component, event, helper) {     var editRecordEvent = $A.get("e.force:editRecord");      console.log("record id is: " + component.get("v.item.Id"));     console.log("editRecordEvent value is: " + editRecordEvent);      editRecordEvent.setParams({         "recordId": component.get("v.item.Id")     });      editRecordEvent.fire(); }   correct?  Here is the odd thing. From the console.logs, I get the record id, but the editRecordEvent returns undefined. What is going on? Is there something I need to reference in my component to use Event Reference? Weird font in system windows Suddenly all the system windows have this weird font. I can't read nor understand what the system is asking me. How can I change it to normal fonts?    I'm using OS X Yosemite 10.10.3 Where can we find frequently updated details about travel/entry restrictions due to Coronavirus (nCoV-19)? Due to the outbreak of nCoV-19 (Novel Coronavirus) many Countries have imposed several entry restrictions. But these are quite confusing for a lot of people. Some countries allow transit through parts of China (like Shanghai) but some restrict transit even through Hong Kong/Macau. Philippines restricted passengers coming from Taiwan too, but I think that that was later changed.  Where can one find a list of such restrictions for all the countries, ideally a source that is updated frequently I want to prove that $xe^{-x}$ is bounded by some constant for all the $x \in [0, \infty)$. So I take derivative of this guy, and found that on $x \in [0, \infty)$, its derivative is positive from $[0, 1)$, $0$ at $x=1$, and negative from (1, in infinity). So  $xe^{-x}$ achieves its maximum in $[0, \infty)$ at $x=1$, which is $1/e$. However, to prove that it's bounded by $1/e$, I need to prove that as $x$ goes to infinity, $xe^{-x}$ converges to $0$. Because otherwise, if it went to some value below $(-1/e)$, $xe^{-x}$ would not be bounded by $1/e$. How can I prove that $xe^{-x}$ converges to $0$? I mean, as $x$ goes to infinity, $e^{-x}$ converges to zero, but at the same time, x diverges to infinity. How can I formally prove that the product term converges to $0$? Do I need to use the epsilon definition of convergence to prove it?  Could you just show me the formal proof of $xe^{-x}$ converges to $0$? Or is there's any other way to approach this question? My professor suggested that I should use the power series for $e^{-x}$...?   Your help is greatly appreciated! Thank you so much!  I hope you enjoy your Saturday! What happens to objects that enter a Stargate from the destination side? We know that matter can only travel one way through a Stargate, ie. from the dialing gate to the destination. What happens to things that enter the wormhole from the destination side?   For example, if someone dials a gate that has tipped on its side (as in the SG-1 episode Hundred Days) and walks through, what happens when he reaches the other side and gravity causes him to immediately fall back into the gate?  Does the matter disappear, or does it pass through to the other side of the destination gate, as if the wormhole were not there?  Related:
