I am a novice photographer. I have a Fujifilm X100T, which has a fixed 35mm-equivalent lens. As today is the supermoon lunar eclipse, I want to capture the moon with my camera. I was wondering if anyone could suggest me good tips in how to shoot such celestial objects using a mirrorless camera.
This weekend is a "Supermoon" (the largest full moon of the year, in perigee, the closest to Earth). Would someone please advise how I could make the most out of my Canon PowerShot to photograph this phenomenon?    What settings should I use?    What times are the best with respect to the exact times of moonrise and moonset provided by the U.S. Naval Observatory? In other words, is it better 30 min before it crosses the horizon? Or just at the crossing? Are there any tips and tricks for a beginner to benefit from?  Are moonrises or moonsets generally better/easier to capture? Are there different techniques for different phases of the moon?   I read that full moon tends to come out flat, but I also want to benefit from the perigee.
Symmetrical twin paradox in a closed universe Take the following gedankenexperiment in which two astronauts meet each other again and again in a perfectly symmetrical setting - a hyperspherical (3-manifold) universe in which the 3 dimensions are curved into the 4. dimension so that they can travel without acceleration in straight opposite directions and yet meet each other time after time.  On the one hand this situation is perfectly symmetrical - even in terms of homotopy and winding number. On the other hand the Lorentz invariance should break down according to , so that one frame is preferred - but which one?  So the question is: Who will be older? And why?  And even if there is one prefered inertial frame - the frame of the other astronaut should be identical with respect to all relevant parameters so that both get older at the same rate. Which again seems to be a violation of SRT in which the other twin seems to be getting older faster/slower...  How should one find out what the preferred frame is when everything is symmetrical - even in terms of GRT?  And if we are back to a situation with a preferred frame: what is the difference to the classical Galilean transform? Don't we get all the problems back that seemed to be solved by RT - e.g. the speed limit of light, because if there was a preferred frame you should be allowed to classically add velocities and therefore also get speeds bigger than c ?!? (I know  is only a local theory but I don't understand why the global preferred frame should not 'override' the local one).  Could anyone please enlighten me (please in a not too technical way because otherwise I wouldn't understand!)  EDIT Because there are still things that are unclear to me I posted a follow-up question: How do I find out the number, type, resolution &amp; refresh rate of additional monitors I can attach to my MacBook or MacBook Pro?  This is an attempt at a canonical QA, as per the Meta QA -   to try prevent the myriad "same but different" questions we get on every possible combination of computers, cable &amp; monitors There are perfectly good resources out there that Ask Different should not have to duplicate the efforts of. Optional Methods in Java Interface Does a log transform always bring a distribution closer to normal? I have a highly right skewed data set with a large range of values (from 1 ~ 10^6) (can't share the actual data for work related reasons).   When I plot the log of the data instead, the distribution looks a lot more like a normal distribution.   Have I stumbled on a meaningful insight in the data set, or is just a general property of the log transform that it brings the distribution closer to normal? Play a Sound with Python What's the easiest way to play a sound file (.wav) in Python? By easiest I mean both most platform independent and requiring the least dependencies. pygame is certainly an option, but it seems overkill for just sound. Infinitely many primes of the type 5 mod 6. Problem: Prove that there are infinitely many primes of the type 5 mod 6.  My professor did the problem and the proof was horribly long. Can someone show me a shorter version of the proof of this problem. Converting from DMS to DD using Python in Field Calculator? I need to convert lat/long that is expressed as degrees, minutes, and seconds in the data into decimal degrees. For example, in the data, they are listed as N335042.06 in the Latitude column, and W86031.04 in the Longitude column. I have done this problem before where I created a script which converted DMS to DD, and vice-versa, so I guess I could use bits from that. But the problem I'm having is how to ignore (for lack of a better word) the 'N' and 'W' in the data? Can I skip them? And DMS are listed all together without any symbols or spaces.  Can I use len(), range(), split() to specify what part to read from the value? For example, can do the following?  N335042.06 where, 33 = degrees 50 = minutes 42.06 = seconds ...?  I came across  ESRI article, but it's in VB. Will probably use it as a reference but some of the terminology/syntax is different from Python.  Final code that works!   # Pre-logic def latDD(x):   D = int(x[1:3])   M = int(x[3:5])   S = float(x[5:])   DD = D + float(M)/60 + float(S)/3600   return DD  # Expression latDD(!Latitude!) How do the comment replies (aka &quot;pinging users&quot;) work?  Who can I send an @reply to? How do I respond to a specific user when entering my comment? Will they be notified? What do people mean when they talk about &quot;pinging&quot; another user?  Related: Is there a single word for "one who speaks/boasts a lot about everything"? I'm looking for a single word to most aptly describe a person possessing the following "qualities":   Appears to be superior in every technology/skill under the sun, which he deems worthy of knowing On being questioned/assigned the task, is found to have only superficial/no knowledge of the said skill. Inherent tendency to "one-up" anyone and everyone - example: "I didn't work hard at all in my undergrad days, but yet I have better/equal grades than you have! "   Could someone help?  Edit: I've got some very good responses, but despite popular opinion for "braggart", I'm going with "pretentious" as it suits what I was looking for more aptly IMHO. A better serial voting trap Currently we capture fanatic, voting ring or rage-type activities, by measuring the number of up-votes or down-votes between the same two users in a certain (relatively short) time period. When this is detected by the system, the votes are reversed, and I've never bothered to investigate what else happens after that - though I'm sure some form of wrist-slapping ensues.  While it is intended to be well-guarded for obvious reasons, the algorithm used is not exactly a secret, and I am sure there are plenty of examples where people are dangling (maybe intentionally, or maybe by dumb luck) just on the safe side of getting caught.  Personally I believe there are active, intentional, long-term vendettas in operation right now where users either:   blindly up-vote every answer from a user; or, down-vote a particular user once or twice a day, regardless of topic or quality.   Now, maybe the first one is valid - if I'm operating in the same tag-sphere as some smart person, it may just be that I'm constantly enthralled with their answers, and I'm not even noticing who they're written by. (Though, even Skeet isn't perfect, and I haven't up-voted every answer I've seen him post.)  But still, can we do a better job of catching - or at least noticing - this activity over the long term in addition to the short term?  The behavior is the same, and shouldn't be tolerated, regardless of the time frame - vengeful rage serial voting, blind staker crush serial voting, and painstakingly patient serial voting are all undesirable behaviors IMHO.  I'm not saying it has to do anything automatically, as I'm well aware of the possibility of false positives. And I'm not even sure what to propose as a time frame or a vote threshold.      But if a large percentage of my up-votes or down-votes are against a particular user, and especially if on a majority of those posts I am the only one voting in that direction, I think it should at least be raised as some kind of flag to moderators.   This would work much like how other suspicious activity is highlighted (but also not dealt with automatically). If a pattern becomes obvious and persists, then they can intervene in some way (or not, but at least they were provided with the information - just like they can reject and ignore manual flags). Today, all I can do is e-mail team@stackoverflow.com, and unless I know exactly which person(s) are involved, there is not much they can do about it.  And you're thinking, "Meh, let some hater down-vote you once or twice a day. Unless all you're posting is utter crap, it should be statistically insignificant." You're right. But reputation is not the point, and is not the motivation behind my request. What I'd like to see curtailed is the tendency for folks to down-vote a question or answer because of who posted it, not because of what it said or didn't say. When a down-vote is personal it can leave a person second-guessing the quality of their post. Which isn't necessarily a bad thing, except when it happens repeatedly.  Sorry for the essay but I wanted to try to anticipate and cover all the objections and hole-poking. If $F\supset E$ and $E\supset k$ are normal extensions. I want a counter-example where $F\supset k$ is not normal Difference between ulimit, lsof, cat /proc/sys/fs/file-max I've been getting java.io.IOException: Too many open files while running a Kafka instance and using one topic with 1000 partitions so I started investigating the file descriptors limits in my ec2 vm. I cannot understand which is exactly the limit for open files on a Centos 7 machine since all the following commands produce different results. The commands are:   ulimit -a: open files 1024 lsof | wc -l: 298280 cat /proc/sys/fs/file-max: 758881 (which is consistent with /proc/sys/fs/file-nr)   If the actual limit is the one the last command produces then I am well below it (lsof | wc -l: 298280). But if this is the case, the output of the ulimit command is quite unclear to me since I am well above the 1024 open files.   but are there all these seemingly "inconsistencies" between these commands? The  from Goblin Punch states the following:     Hungry Coffin   HD 6 AC 14 Slam 2d6 or 2d8 Swallow 1d6 + swallow   Fly 9 Int 5 Morale 12   It says the Hungry Coffin has "HD 6". This doesn't help me at all, because I still don't know what its average HP is, or how to roll its HP. How do I figure this out? Thanks! SEVERE: A child container failed during start java.util.concurrent.ExecutionException: org.apache.catalina.LifecycleException: I am quite new to DSLRs and one of the first things I noticed was the incredible focus points and appearance of depth that you can achieve. That is great in a lot of scenarios, but not in all. When filming a landscape as a whole, I do not want to have the focus on that single tree, but on the whole skyline.  Is there a way by which you can sort-of "disable" the focus, so that the raw image is recorded without any added blur? I suppose something as simple as this is only a small function you can turn off, but I can't seem to find it in the manual of my camera. I understand that the Announcer badge can be earned if the question is visited 25 times.  But is this only when I share a link to this question in one of my answers, or can I also share the link (with my user id somewhere to count the accesses) somewhere else, maybe Facebook? Headers and font in KOMA-script I am setting up the layout for my bachelor thesis using scrbook as basis for a self-made documentclass with twosided print. I want a header containing the current part number and name on the outer side (left on even pages, right on odd pages), the current chapter number and name on the center of the head and the same for section on the inner side. I found this example in the KOMA-Script documentation:  \usepackage{scrlayer-scrpage} \pagestyle{scrheadings} \automark[chapter]{chapter} \automark*[section]{}   It puts the chapter on the outer side on even pages and the section on the outer side on odd pages. Sadly, I was not able to modify this to fit my needs because I do not really understand the way KOMA-Script works here. If a part starts but there is still no chapter in it, the place for the chapter shall remain empty (same for chapter and section). Can anyone help?  Furthermore, I would like to change all fonts that KOMA-Script changes (e.g. toc, section, chapter...) back to the default computer modern as I do not like the font KOMA-Script uses here. Is there a better way than changing all the fonts manually like this:  \addtokomafont{section}{\fontfamily{cmr}\selectfont} Sharing Test code in Maven Avoiding Windows 10 Creator, but not other updates I try to add an item to my sharepoint list from a custom web part.
