Disk full, du tells different. How to further investigate?
How can I manage the "Open with Explorer" button based on user permissions? How can I mine redstone ore? I found redstone ore in Survival Mode (Minecraft Pocket Edition) and tried to use all five tools to collect it. It took about a minute or two to break, but I couldn't collect anything from it once broken.  How do I mine redstone ore? Combinatorial argument to prove the recurrence relation for number of derangements Give a combinatorial argument to prove that the number of derangements satisfies the following relation: $$d_n = (n − 1)(d_{n−1} + d_{n−2})$$ for $n \geq 2$.  I am able to prove this algebraically but not able to see the combinatorial example. bisectors of an angle in a triangle intersect at a single point - proof verification Let´s consider a general triangle ABC. Let´s draw two angle bisectors from vertices A and B.  It is obvious that these two angle bisectors intersect at a single point X. Since X lies on the angle bisector from A its distance from side b is the same as its distance from side c. As X also lies on the angle bisector from B, its distance from side c is the same as its distance from side a.  By transitivity the distance from the point X to the side b has to be the same as the distance from X to the side a. Therefore the angle bisector from C (which is the set of points equidistant from b and a) has to go through X.  It seems as a very simple argument. Is it correct? Can't get RTL8125B working on 20.04 Finding the maximum likelihood estimator (Theoretical statistics) Let $X_1, X_2, ..X_n$ represent a random sample from this pdf:  $$f(x|\theta)= \frac{3x^2}{\theta^3}, 0\leq x\leq \theta$$ (with 0 elsewhere)  Could someone explain how I would find the maximum likelihood estimator (MLE) of this pdf? I know I have to get the likelihood function L, then the log likelihood function, then differentiate, but I am getting lost in the calculations. Thanks! Best way to extract a subvector from a vector? Suppose I have a std::vector (let's call it myVec) of size N.  What's the simplest way to construct a new vector consisting of a copy of elements X through Y, where 0 &lt;= X &lt;= Y &lt;= N-1?  For example, myVec [100000] through myVec [100999] in a vector of size 150000.  If this cannot be done efficiently with a vector, is there another STL datatype that I should use instead? Use of "though" versus "however" Consider the sentence      E-books are on the rise, but they haven't suppressed paper books though.    This usage seems to be quite common, but when I learned English  I was taught to use "however" where I now read "though". My questions on this use of "though" are:     Is this a new trend? Is it restricted to American English? Is "though"  considered more colloquial than "however" ?    And on a syntactic level: Do you put a comma before "though"? I have installed Google Drive on Windows Server 2008 R2. When I login to the server, Google Drive starts automatically and synchrnoizes files, pulling changes down from the cloud. All good so far.  However, I would like the sync to run even if I am not logged in. Is there any way to start the sync process automatically, maybe as a scheduled task?  I have other jobs on the server which distribute the files by FTP so I would like the server copies of the files to be up to date. Yes, I know the topic has been discussed before. I know that Meta already has threads that complain about how flagging doesn't work. I wanted to give a practical example.  Today, a  came in to the  chat and asked the :  Hey guys, as soon as I embed javascript, all my html elements are gone. Even if the script is empty!? ...Can anyone help out? The example is really minimalistic &lt;script type='text/javascript' src=&quot;http://ajax.googleapis.com/ajax/libs/jquery/2.0.3/jquery.min.js&quot;/&gt; &lt;script type='text/javascript' src=&quot;script.js&quot;/&gt; These lines make everything vanish. script.js is empty! I use google chrome and the file is on localhost  Some context:  The JS room encourages people to come and ask questions that are too small/badly put for main. The room encourages people to just ask questions rather than ask to ask. In fact we even have a bot that prompts users to just ask if they have a question whenever they join. The above user has a good Q to A ratio having 1K rep in the main site and over 80 answers. The user has no negative context in the chat. No previous offenses or anything like that.  That message got 7 flags  Had a mod (ThiefMaster) not been present and invalidated those flags in time that user would have probably been suspended from the chat. This is bad, it sends the wrong message and it is very rude. Now, some other rooms don't allow people to just come and ask questions right away so maybe users from other rooms validated the flag. Maybe users thought he was being rude? I don't know. I do know that we don't want this sort of negative atmosphere in the JS room (and I'm sure other useful rooms such as PHP don't want it either), we have enough on our hands trying to maintain a community while helping people joining and handing with vamps/trolls. Possible solutions:  Drop spam/offensive flags altogether. Make spam/offensive flags room specific for big enough (tm) rooms. Give room owners just the ability to invalidate spam/offensive flags. Following , I would like to know what exactly it means for a tag to be marked as blocked (formerly blacklisted) on a Stack Exchange site.  Does it mean I can't use that tag on my question? What are the reasons for blocking a tag? Who can block tags? Why am I being prompted to remove a tag from a question I'm editing? How do I verify that a string only contains letters, numbers, underscores and dashes? I know how to do this if I iterate through all of the characters in the string but I am looking for a more elegant method. Multiple Inheritance in java Persistent Network Configuration using KVM and libvirt Quotient rings of Gaussian integers How do I transcode a Javascript string to ISO-8859-1? I'm trying to get apache to redirect from http to https, however I want them both on the same port (20100, but I doubt that will matter). Basically what's going on  except I'm not doing this for webmin. Currently I have it configured to serve HTTPS, and when I access with HTTP I get:  Your browser sent a request that this server could not understand. Reason: You're speaking plain HTTP to an SSL-enabled server port. Instead use the HTTPS scheme to access this URL, please.   There seem to be a lot of somewhat similar questions, however I am unable to find one that actually answers my question. Defend against flag spam in chat We have incidents where we get 10+ flags from the same room in rapid succession. This happens on multiple occasions and we have reason to believe it's a single user doing this.  I don't think it's of value to allow a single user to flag more then n messages in a small time period.  If we could have some anti-flag spam measures put in place, then that would be great. Allow users to leave an anonymous comment when voting I don't know if people don't explain why they up or down vote because they don't care or because they don't want the person to know they voted on an answer (or question)... But, it might be nice to be able to leave a comment anonymously as to why it was voted.  It could give us more insight as to people's thoughts on posts.    Really, I think this would come into play a lot more dealing with down votes more than up votes, but I could see it being beneficial in both situations.   See also Let $f:S^{2n} \rightarrow S^{2n}$ be a continuous map. Show that          there exists $x \in S^{2n}$, such that $f(x) =x$ or $f(x) = -x$;   any continous map $g: \mathbb R P^{2n} \rightarrow \mathbb RP^{2n}$ has a fixed point;      I think 1 implies 2. So, how can I find an $x$ in 1?  Thanks for the help.
