Is it possible, or is this a procedural generation bug?
I keep running into areas where I see a chest in a section of the room that seems completely walled-off. Is there any way to get to these, or is that just the randomly generated dungeon being a tease?  I had to splice two screenshots together to show an example of what I'm talking about:   Is there any way to get in there?
How do you return to the default view (the one you see when blender starts)? In Uzbekistan I was stopped, searched and questioned six times in one day.  At the border with Tajikistan, one official tried hiding my paperwork to elicit something from me.  In Kyrgyzstan, I was physically harassed and detained by the police, and about US$30 taken while they searched everything on me and a Dutch backpacker I was going to get food with.  I'm not particularly dodgy looking - it's happening to a lot of backpackers I meet.  Tourists are apparently a prime target for corrupt officials.  Any suggestions or tactics for avoiding these occurrences?  Aside from carrying only photocopies of your passport so that they can't hold your passport ransom, I've not heard many successful tips... I want to add a comma in the thousands place for a number.     String.Format()? I've somehow lost my id_rsa.pub file. I still have my id_rsa file. How do I recover the public key from the private key?  (This question came up after ssh-copy-id was reporting "ERROR: No identities found" while ssh-keygen reported "/root/.ssh/id_rsa already exists". ls ~/.ssh pointed out the problem was having id_rsa but not id_rsa.pub. I found the solution, but it was buried at the bottom of a long post on an Ubuntu support forum.) How do I safely delete all files with a specific extension (e.g. .bak) from current directory and all subfolders using one command-line? Simply, I'm afraid to use rm since I used it wrong once and now I need advice. My regex is matching too much. How do I make it stop? I have this gigantic ugly string: J0000000: Transaction A0001401 started on 8/22/2008 9:49:29 AM J0000010: Project name: E:\foo.pf J0000011: Job name: MBiek Direct Mail Test J0000020: Document 1 - Completed successfully  I'm trying to extract pieces from it using regex. In this case, I want to grab everything after Project Name up to the part where it says J0000011: (the 11 is going to be a different number every time). Here's the regex I've been playing with: Project name:\s+(.*)\s+J[0-9]{7}:  The problem is that it doesn't stop until it hits the J0000020: at the end. How do I make the regex stop at the first occurrence of J[0-9]{7}? Pass a PHP string to a JavaScript variable (and escape newlines) What is the easiest way to encode a PHP string for output to a JavaScript variable?  I have a PHP string which includes quotes and newlines.  I need the contents of this string to be put into a JavaScript variable.  Normally, I would just construct my JavaScript in a PHP file, à la:  &lt;script&gt;   var myvar = "&lt;?php echo $myVarValue;?&gt;"; &lt;/script&gt;   However, this doesn't work when $myVarValue contains quotes or newlines. How do I format my code blocks? How do I post text so that it is formatted as code?  What do I need to do so that my code shows up properly &mdash; not escaped or removed &mdash; when posted? And how to get the correct syntax highlighting?     For more information, see "" in the . init.m in Autoload directory is not read by parallel kernels in M11.2 Can I use a one time pad key twice with random plaintext? I understand the basics of OTP: $|\text{key space}| = |\text{plaintext space}|$ implies perfect security, key reuse destroys this.  Cryptanalysis on the $N$-Time Pad for $N &gt; 1$ involves finding patterns in the ciphertext; this, however, all seems based on the premise that patterns exist in the plaintext (e.g. English language).  My question is: if $m_1$ and $m_2$ are two truly random strings, and they are both encrypted with the same OTP key to yield $c_1$ and $c_2$, is it possible to recover $m_1$ and $m_2$ from $c_1$ and $c_2$?  In other words: while "perfect security" (aka perfect indistinguishability) is obviously lost (constructing a distinguisher for two messages is trivial), is the plaintext still safe? A coin with heads probability $p$ is flipped $n$ times. A "run" is a maximal sequence of consecutive flips that are all the same. For example, the sequence HTHHHTTH with $n=8$ has five runs, namely H, T, HHH, TT,H. Show that the expected number of runs is  $$1+2(n-1)p(1-p).$$  I have tried to use some generating function on this but calculus got pretty messy and didn't work. What is the Unix command to create a hardlink to a directory in OS X? How do you create a hardlink (as opposed to a symlink or a Mac OS alias) in OS X that points to a directory? I already know the command "ln target destination" but that only works when the target is a file. I know that Mac OS, unlike other Unix environments, does allow hardlinking to folders (this is used for Time Machine, for example) but I don't know how to do it myself. Beamer: how to justify the whole text? Sort by author in Alpha bibliography Using the alpha bibliography style, citations are sorted by the citation key. I'd like to use the same style of authors-year citation keys (e.g., [CP92]) but have the bibliography sorted by the first author's lastname instead of alphabetically by the citation key itself. This would keep the same papers by the same first author together.  For example, alpha would produce the following sorted order:        [Cha81] D. Chaum. Untraceable...   [CL04] J. Camenisch and A. Lysyanskaya. Signature...   [CP92] D. Chaum and T. Pedersen. Wallet...      Whereas, abbr would produce the following sorted order:        [1] J. Camenisch and A. Lysyanskaya. Signature...   [2] D. Chaum. Untraceable...   [3] D. Chaum and T. Pedersen. Wallet...      I am looking for the same sorting as abbr but maintaining the citation key style of alpha.  Is there a way to achieve this hybrid style? How to get rid of banding in illustrator while using gradient? How to get Rid of Banding in illustrator while using Gradient Is it okay to vectorize this image to make a poster out of it even though the image is not Creative Commons or anything like that? I'm not using any part of the image directly and only going to use it as a guide to make my own SVG version.  This is the image:    Here is .  It says that it is CC licensed but the original NatGeo one isn't, I don't think.  I don't plan to make money off it or anything, I just want a nice poster and the quality of the original isn't that good. $f$ differentiable except in $1$ point Assume we have a function $f : \mathbb{R} \rightarrow \mathbb{R}$ such that  $f$ is differentiable for all non-zero $x$, $f$ is continuous at $0$ and  $$\lim_{x \uparrow 0} f'(x) = \lim_{x \downarrow 0} f'(x) &lt; \infty. $$  Is it then true that $f$ is also differentiable at $0$?  If we drop the hypothesis that $f$ is continuous, this is not true since the signums function is a simple counterexample. But what if $f$ is continuous? I don't think this is true but I can't find a counterexample... Who are the Steam Mascots? So with the Steam Summer Sale in full swing, I've finally taken notice of the Steam Mascots.  Judging by the latest background, the black one, at least, has a name: Cyl.  Do the other two have names as well? Are there only these three?   What's their story? Image uploads from the editor strip preceding line breaks Recently, using the image uploader in the post editor has starting stripping preceding line breaks; placing the image directly after any previous text instead of at the current cursor position. This means that the inserted image is placed inline as part of the previous line of text rather than in a new paragraph as it did previously...  Before inserting the image (note the cursor position):        After inserting the image:        This also happens after the Markdown for a horizontal rule, which destroys the rule and gives us a bunch of hyphens followed by an image instead:        Seems the behaviour is a bit inconsistent... Sometimes I get the behaviour shown above and sometimes it leaves a single newline, I'm not sure when or why but single line breaks are ignored in Markdown so the rendered result is the same regardless.  Obviously it's useful to be able to have inline images, but I'm pretty certain most images aren't intended to (and shouldn't) be. I would like to get the path to the execution directory of a Windows Forms application. (That is, the directory in which the executable is located.)  Does anyone know of a built-in method in .NET to do this?
