Can I roll a d10 twice for rolling percentiles?
When rolling percentages, do 1d100 and two d10s (percentiles) share the same probabilities?
Why are there hexagonal holes in my donut? I'm currently making a donut using blender gurus tutorial. I have no idea why, but there are holes in my icing. Does anyone know what could be causing it? Thanks for any help. Controlling the direction of curve extrusion Is there an easy way to control how the extruded width of a curve object is oriented, for example like this     or this     The curve in the images above has only two control points, and I got the effect by rotating one of the points. However, for a curve with lots of control points it would be somewhat difficult or at least tedious to achieve this. Is there a simpler way? Reordering polygon shapefile permanently? I have secured a visa for the US, be it an ESTA or another visa requiring me to go for an interview. My understanding is that obtaining a visa for the US does not guarantee me entry into the country. Rather, :  Entering the United States A visa allows a foreign citizen to travel to a U.S. port-of-entry (generally an airport) and request permission to enter the United States. A visa does not guarantee entry into the United States. The Department of Homeland Security (DHS), U.S. Customs and Border Protection (CBP) officials at the port-of-entry have authority to permit or deny admission to the United States. If you are allowed to enter the United States, the CBP official will provide an admission stamp or a paper Form I-94, Arrival/Departure Record.  What happens once I arrive in one such port-of-entry? Will I have to go through customs checks? Will I have to talk to an immigration officer explaining my reasons for visiting the US? What documentation, if any, should I bring? Is the documentation I brought for the interview enough? What if I did not attend an interview since it was not required (for example if I obtained an ESTA online)?

I'm just going to throw this out there, but Google indexes Stack Overflow really quickly For example, I  after using Google to try to find an answer. I then turned back to Google and did a search for  and it was already the first result! Similar searches also put my question on the first page, usually in the top 5!  This is insanity. Did I get lucky and post just before an indexing? Is the popularity of SO leading to Google indexing extremely frequently? Or is Jeff using some kind of crazy SEO? Prove that $∂A$ is closed given $∂A = \text{Cl}(A) − \text{Int}(A)$ Similar questions have been asked, but none with the given information. My textbook doesn't give me the fact that  $∂A = \text{Cl}(A) − \text{Int}(A)$. If that were the case, I could just state that definition and note that it's the intersection of closed sets.   I have very little knowledge of set theory and proofs, so I'm not sure how else to prove this. As always, I appreciate any help.  The question comes from “Introduction to Topology: Pure and Applied” by Colin Adams and Robert Franzosa.   "Let $A$ be a subset of a topological space $X$. Prove that $∂A$ is closed given  $∂A = \text{Cl}(A) − \text{Int}(A)$" Is the following sentence correct English?      Have you the address?   The address in question is obvious to the person being asked.  It's normal to ask such a question as "Do you have the address?" or even "Have you got the address?" But is it acceptable to use just the verb have without do or got? Is it possible to make the default scene fill two monitors at startup? I know how to set up the default scene by pressing Ctrl+U, but whenever I startup Blender it always fills only one of my screens, even if I set it to fill both before setting the default scene. I end up having to resize it every time I start it up. Is there a way to set this to happen by default? How to plot an emission spectrum? Are there any good tools besides SeleniumRC that can fetch webpages including content post-painted by JavaScript? One major shortcoming of curl is that more and more wepages are having their main piece of content painted by a JavaScript AJAX response that occurs after the initial HTTP response. curl never picks up on this post-painted content.   So to fetch these types of webpages from the command line, I've been reduced to writing scripts in Ruby that drive the SeleniumRC to fire up a Firefox instance and then return the source HTML after these AJAX calls have completed.  It would be much better to have a leaner command line solution for this type of problem.  Does anyone know of any? Equivalent of "former" and "latter" for more than 2 items Former and latter are valid only when there are two choices.

View history of commands run in terminal Is there a way to save all my typed terminal commands and view it like history in a log book? Imputing missing observation in multivariate time series The orbit of satellites around Earth eventually decays, or so I read. This is typically caused either by atmospheric drag, or by tides. I would assume most satellites have a limited service life in orbit. Hence the question - What is the typical orbital life of a satellite? How long before it's successor must be launched into orbit ?

SQL injection that gets around mysql_real_escape_string() Show timestamp of a vote in the tooltip when mousing over it Sometimes I come across an old question or answer that I voted on in the past, but I don't clearly remember when (or sometimes even why) I voted it up or down. Being able to see the date/time that I cast a vote would help me remember my mindset at the time.   When mousing over the toggled vote, the tooltip reads the same as if I hadn't voted, with no further information. For example:     This answer is useful (click again to undo)   The only way to get the timestamp is if I try to click the vote to undo it and get the locked vote message:     You last voted on this answer [datetime] Your vote is now locked in unless this answer is edited   However this requires me to guess that the vote is locked - if there was an edit since then I'll actually undo the vote and erase the info I was looking for.  Feature request: Please add the vote timestamp to the tooltip when mousing over a cast vote. This is already done with the green acceptance checkmark for example.
