Path destination too long
How to delete a file with a path too long to be deleted
I used sculpting on a plane, and things looks great. However, when I press P to play, the whole ground become a mess. I can see through it in various places, and there are also nasty looking black edges everywhere.  another problem, I made a UV Sphere to display the sky, but when I press , P to play it disappears! Can I award user with special bounty after accepting his anwer? I have a , and I haven't start a bounty for this question. After I got my answer I'd like to give a user a special bounty, because I consider his answer very helpful and it saved me a lot of time. I've already accepted the answer. Is there a way how can I give him some bounty?  Thank you Coconut Water from White vs Brown Coconuts Does electricity flow on the surface of a wire or in the interior? Touchpad stopped working 20.04 How to use downloaded fonts with pdfLaTeX on Ubuntu I want to use the  font in my pdfLatex document.  What steps should I do for using a downloaded font   Should I download the TTF or the OpenType version? Where should I store the font? Should any font processing be done? How can pdfLatex find this font?   I am using TexLive 2011 installed in a custom location (/somepath/texlive/2011) on Ubuntu Intersection of the $p$-sylow and $q$-sylow subgroups of group $G$ I have been reading about the new Salesforce async triggers. Currently, I tend to handle these sort of needs with a trigger that passes data to a 'Handler class' that would evaluate if a certain change has occurred. If it has then we pass those Ids to a queueable class for further processing.   What advantage do CDC and async triggers offer over using queueable or batch apex? I'm struggling with the following question;     For every graph $G$ such that $K_3 \not\subseteq G$ (i.e. $G$ does not contain a triangle), prove that $\chi(G) \leq 2\sqrt{n} +1$ (where $\chi(G)$ denotes the chromatic number).   Any hints? I really cannot see the connection between the triangle-free nature of $G$ and a chromatic number being bounded above by $O(\sqrt{n})$. Which browsers are officially supported, and what else do I need? Etiquette, rules, or advice on which site to pose a question? (Or, why are there so many StackExchange sites?) Basically: I have a question I want to ask regarding using Apple's AppleScript/Objective-C bridge (Objective C wrapped in AppleScript, basically) to implement an HTML/WebKit-based pager (a drop-in for less, like vimpager) and a HTML-ized manpage writer, which should also be capable of rendering to PDF via pandoc/pdftex, etc.  Is this a:   Stack Overflow question? (C/Objective-C, APIs) Ask Different question? (AppleScript) Unix &amp; Linux question? (implementing a pager which is a drop-in for a *nix utility) TeX question? (PDF rendering) All of the above?   Where and how should I ask this, in order to increase the likelihood of the "right person" seeing it?    Edit: I believe this question was too hastily closed as a duplicate.  While the best answer to this question is indeed identical to answer to the other:     Ask the question on the site you think is most applicable. If ... it does not get any answer,   ask a moderator to migrate the question, or alternatively, delete it and re-ask it.   The so-called "duplicate" in question asks     Is cross-posting permitted on multiple Stack Exchange sites if the question is on topic?   whereas this question asks,     Where and how should I ask this [ question that is on topic on multiple Stack Exchange sites? ]     That is to say, if two similar but materially different questions have identical answers, it does not necessarily follow that the questions are likewise the same.  Calling them duplicate questions does a disservice to both and the site in general I think. Batch renaming files with pattern I have some files named like these:  63018933.mp4?token=1325697436_b0c3e70c6e339380b4a484c576a8c287  63808488.mp4?token=1325697401_4ae5f7a68d93873c8881b303e7655e14  How do I rename all them to, for example 63018933.mp4(remove characters after mp4)? Why do I see a saddle in this picture of a computer screen? I am not entirely sure this is an appropriate question for PSE, however since many of you have such diverse backgrounds, I'll give it a shot.  I have noticed that when one takes a picture of a computer, TV screen with a phone, you can "see" what looks like a saddle phase portrait.     Why does this happen? Does it have any relevance to differential equations or other areas of math? Will Windows 10's reset delete my Linux partitions? I'm having exactly the same issue as , also using Biber 2.14, albeit I didn't upgrade, downgrade, change TexLive version, change encoding or (seemingly) do anything. It's like Biber suddenly quit parsing dates on me.  Whether the bibfile is encoded in ASCII or UTF-8 makes no difference. Whether the date is a short format or the full YYYY-MM-DD makes no difference. I'm not sure what else to test.

In Termux I print the working directory with pwd and it shows $HOME/storage as:  /data/data/com.termux/files/home   My internal storage looks like this:  . ├── Alarms ├── Android |   ├──data |   |  ├── ... |   |  ├── com.termux |   |  |   └── files |   |  |       └── 0 items |   |  └── ... |   └── ... ├── DCIM ├── Download └── ...   My external storage looks like this:  . ├── Android |   ├──data |   |  ├── ... |   |  ├── com.termux |   |  |   └── files |   |  |       └── 0 items |   |  └── ... |   └── ... └── LOST.DIR   Neither my internal storage, nor my sd card, contain a /data/ directory at the root level. Where is this /data/ directory? For that matter, where is the root /storage/ directory? Where is the root /emulated/ directory? Where are any of these directories and why cant I access any of them? Its very easy to prove $p\mid n^p-n$ for p=3,5,7, it fails for p=9 because $$     (n+1)^9-(n+1)= n^9+9n^8+36n^7+84n^6+126n^5+126n^4+84      n^3+36n^2+8n $$ and $84= 2²\times 3\times7$. Is it true for any $p$ prime? I have checked many primes, but have no idea for the general case. Why NuGet adds app.config with assemblyBinding to LIBRARY projects during a NuGet package update? Integrating $\int^2_{-2}\frac{x^2}{1+5^x}$ $$\int^2_{-2}\frac{x^2}{1+5^x}$$  How do I start to integrate this?  I know the basics and tried substituting $5^x$ by $u$ where by changing the base of logarithm I get $\frac{\ln(u)}{\ln 5}=x$, but I got stuck.  Any hints would suffice preferably in the original question and not after my substitution.  (And also using the basic definite integrals property.)  Now I know only basic integration, that is restricted to high school, so would prefer answer in terms of that level. As the question title suggests, how do I see that every left ideal of a square matrix ring over a field is principal?
