Whenever I add a text object it always defaults to Bfont. How do I change that? I have not seen any settings in the user preferences. (However there is a setting to change the UI font.)
I have been playing with the settings for the text object recently, and every time I add a new text object, I need to change the font to my favorite one. (Eurostile LT ExtendedTwo) Is there any way to change the default font so I do not need to change it every time I add a new text object?   Example:
Are any of the USB ports on a Macbook Pro "always on" Always on USB ports will provide power to a device even when the laptop is shut down. Obviously this can be problematic for battery issues, but sometimes a user wants this capability all things considered.  Do the Macbook Pro offer this on any of the USB ports and if not is there any chance its wired and just has to be enabled? What is tail recursion? What exactly is the difference between a parametric and non-parametric model? I am confused with the definition of non-parametric model after reading this link  and .   Originally I thought "parametric vs non-parametric" means if we have distribution assumptions on the model (similar to parametric or non-parametric hypothesis testing). But both of the resources claim "parametric vs non-parametric" can be determined by if number of parameters in the model is depending on number of rows in the data matrix.  For kernel density estimation (non-parametric) such a definition can be applied. But under this definition how can a neural network be a non-parametric model, as the number of parameters in the model is depending on the neural network structure and not on the number of rows in the data matrix?  What exactly is the difference between parametric and a non-parametric model? In the annual rep league, why isn't the difference between rep earned this year and total rep always the same? In the  here on Meta Stack Exchange, it shows that I've earned 9,876 rep this year, and 10,359 rep overall. (It's updated every day at 0:00 UTC, and I so far have earned 1 rep today, since an answer I downvoted a while ago was deleted.)  The difference between my total rep and the rep I earned this year is 483, which means 483 of the rep I've earned is rep I earned in 2017 or earlier. This amount normally never changes, though I can see some reasons why it might change, such as if rep is recalculated and something affects a rep event occurring in a previous year (e.g. a vote from last year was invalidated due to user deletion, a post I made at that time was deleted or undeleted, etc.)  This amount, 483, was a recent change; it used to be 461. Ordinarily, I'd chalk this up to a rep event from last year being recalculated, but I've gone through my full rep history and I can see nothing of the sort happening. On the other hand, on the same day that this number changed from 461 to 483,  was undeleted, recalculating my rep and giving me back 22 (which happens to equal 483-461). It therefore makes sense if that post was from a previous year. However, the post is from this year, so it doesn't make very much sense.  Is there a bug in the way yearly rep in the rep league is calculated, in that rep regained from an undeleted post made the same year is not re-added to the rep earned this year (while it is subtracted properly upon deletion)? Or is there some other event that occurred in the three weeks before 2018 that I had my account that caused this difference to change, that I'm not seeing, and the change being equal to that is just a coincidence? Should we use plural or singular for a fraction of a mile? I have seen people say both 0.25 mile and 0.25 miles. Should we use plural or singular for a fraction of a mile? How to show $a,b$ coprime to $n\Rightarrow ab$ coprime to $n$? Let $a,b,n$ be integers such that  $\gcd(a,n)=\gcd(b,n)=1$. How to show that $\gcd(ab,n)=1$?   In other words, how to show that if two integers $a$ and $b$ each have no non-trivial common divisor with and integer $n$, then their product does no have a non-trivial common divisor with $n$ either.     This is a problem that is an exercise in my course.   Intuitively it seems plausible and it is easy to check in specific cases but how to  give an actual proof is not obvious. The Quotation Mark character in TeXworks editor has vanished Now, my version of TeXworks is 0.4.5r.1280 and I can't have the " character on the keyboard.    I have ``  or '' instead. Why?  And It's the same with Alt+034. I'm very disappointed with that. What happens when I terminate a process and the socket send buffer is not empty? In Windows (and probably in other operating systems), if a process has a TCP connection with another process on another machine, and then I terminate the process, an RST packet will be sent to the other machine to indicate the end of the connection.  Now imagine that when the process is terminated, there were still some data left in the send buffer. What will happen in this case, will these remaining data be sent to the other machine followed by an RST packet, or will these remaining data be ignored and only an RST packet is sent? The MySQL manual at  covers this.  Usually I just dump the database and reimport it with a new name. This is not an option for very big databases. Apparently RENAME {DATABASE | SCHEMA} db_name TO new_db_name; .  This needs to work with , which stores things very differently than . What OpenType math fonts are there available for usage in TeX/LaTeX, e.g. with the unicode-math package?

Duplicate user in reputation league So I understand that this has happened in the past: , but all of the &quot;duplicate&quot; posts are marked as  so here is a new bug report: On the , I am listed twice:  While that's fun and all, it isn't exactly right. What happened to the voting buttons? Starting from yesterday, the up-/downvote buttons seem to have moved from the left of a post towards above (in the middle) of the bodies of all questions and answers. Here is a screenprint of a sample (containing such buttons for both a question and an answer to it):    This happens on an iOS device (running 9.3.5), using various browsers and this in any SE site. No idea so far how it looks like in the most recent iOS version. Same for the (green) checkbox below those voting buttons (to mark an answer as accepted). Is this intended to be like this (IMO it looks ugly ... and a huge waste of available space), or is it rather some sort of CSS related issue that needs to be fixed? PS: Looking at the same page around the same time on a Win PC (using any of the common browsers) seems to work fine. df -h - Used space + Avail Free space is less than the Total size of /home As the output of df -h shows here, something is eating up 5GB of free space. So, it's not available to use.   I'm also noticing sometimes that the hard disk gets filled up to 100% sometimes. So, I had to restart the machine or delete some unncessary files. Only noticed these in /home partition. Don't know whether these two are related, but appreciate if anyone can put some insight into this.  $ df -h Filesystem            Size  Used Avail Use% Mounted on /dev/sda8             100G   92G  2.7G  98% /home Scroll to bottom of div? I am creating a chat using Ajax requests and I'm trying to get messages div to scroll to the bottom without much luck. I am wrapping everything in this div: #scroll {     height:400px;     overflow:scroll; }  Is there a way to keep it scrolled to the bottom by default using JS? Is there a way to keep it scrolled to the bottom after an ajax request? Legendre symbol, second supplementary law $$\left(\frac{2}{p}\right) = (-1)^{(p^2-1)/8}$$ how did they get the exponent. May be from Gauss lemma, but how.  Suppose we have a = 2 and p = 11. Then n = 3 (6,8,10), but not  $$15 = (11^2-1)/8$$  n is a way to compute Legendre symbols from Gauss lemma: $$\left(\frac{a}{p}\right) = (-1)^n$$ Proving that two matrices are congruent, in order to establish a rank and signature result. So, my friend just implemented a bunch of new mods into his SMP server, which meant a host of new commands to play with.  I thought I'd give the /mobspawn command a few goes, and see what I could achieve.  So I headed off to the server's jail (I forget why this particular location compelled me), and gave it a few spins.    I seem to have made a bit of an error in judgement.     What can I do to get rid of this mess?  Is there a command or some other technique I can use to clear out any mobs in my immediate vicinity? Difference between "try to do" and "try and do" What is the difference between try to do and try and do?  To me (non-native speaker), asking someone try and do this seems a bit rude. It's like saying you can try all you want but this must be done: try and fail is not an option. However, asking someone try to do this means I am asking you to try: success is bonus, failure is OK. How to change user in WinSCP? I'm using WinSCP to access Unix computers. How can I change user after I have logged into a Unix server using WinSCP?  E.g. I have personal account in Unix computer A. I can log into this computer using PuTTY and then change user to root user  $sudo /usr/bin/su - rootuser   How can I do the same thing using WinSCP? I don't know the password for rootuser.
