I accidently pinned my own message. I managed to unpin it, but it still remained as starred.  When I try to unstar the message I get a message saying that I can not star my own message, and the message remains starred.  So there are two issues here:   The error message is incorrect, and; It is not possible to unstar the message.    Here is a screenshot:    FWIW, I am the room owner.
Some months ago, I linked to  in the CSS chat room and  in case anybody who cared happened to drop by:  In case anybody else noticed that  questions are now highlighted a little differently, I'm actively investigating this; here's the meta thread  It was unpinned quite some time ago by one of the other room owners. I don't need it anymore anyway since the issue has been . I notice, however, that it's still visible in the starred list, with the only regular (not pinned) star being my own:  When I try to click on the star to unstar it, chat thinks I'm trying to do otherwise and simply tells me I can't star my own messages. I can easily delete this message, but I'd very much like to unstar it instead, thankyouverymuch.

I have told it to put the file in the tmp directory (although this can be changed if needed).  This is run as part of a cron job, the user is an "export" user set up especially for this task. The end goal is for the exported file to end up in /home/export/created_file.csv.  1) postgres can't stash the exported file straight into the home directory of another user without setting up the folder to be overly permissive.  2) the export user can copy the file from /tmp to it's home directory, but then can not clean up (delete) the postgres owned file in /tmp.  This is a daily process and so old files will need to be deleted in some way. I can add a cron job to clean up the files afterwards but I was hoping for a cleaner solution - either a way to change the permissions on the file that postgres creates, or some way to give the export user the additional permission of being able to delete that file in advance of it's creation.  Giving the export user the same permissions as postgres in general however isn't an option, as it would then have free reign over the database.  Any advice, be it unix based or postgres based would be very welcome, thanks. Why does the introduced part-title in letter appear twice? Determining audio level peaks with ffmpeg Is there a plugin I'm missing that allows me to determine the volume samples over the length of an audio file?

Find $a$ such that $(x+a)(x+1991)+1=(x+b)(x+c)$ with $a,b,c\in\Bbb Z$ Find all integer values of $a$ such that the quadratic expression $(x+a)(x+1991)+1$ can be factored as a product $(x+b)(x+c)$ where b and c are integers.   I tried to do it by comparing the two expressions but I can't proceed. Does installing and using Wine open up your Linux platform to Windows viruses?

Height of an HTML select box (dropdown) Can someone confirm that its not possible to change the height of a dropdown that is shown when you click on a select box.

I've tried without much success to add a curved line feature to the ArcGIS JavaScript map.    I created a polygon with a curved edge in ArcMap:   However, when I load this same feature in the web API, it becomes segmented:   The problem started when I tried to create a curved feature from the JavaScript API itself, which only seems to allow full circle features (not circular arcs).  This makes me think that curves are still unsupported in the JavaScript API. Do you know any way around this? Do you have any other ideas on alternatives I can use to create and correctly view curved features? I have a sentence that contains a number of long dataset names. I would like to allow LaTeX to break these names at certain positions that I would like to specify somehow just like I can use \- to allow a word break with hyphenation. But: I would like LaTeX not to insert a dash (which could be mistaken as belonging to the dataset name). How can I do this?   (Something similar is realized in the url package so I guess I could just read that code :) I would not like to use the url package here to be able to make a syntactical (and typographic) difference between urls and datset names.) "To do this" or "For doing this" to start explaining something? Many questions have been asked and answered about "to + bare infinitive" vs "for + gerund" in the middle of a sentence.  However, when one wants to start explaining something, what is better? For instance:  "Now, let us focus on baking the bread.   To do this, start by turning the oven on.", or For doing this, start by turning the oven on."?   Are there even better expressions? I have not found anything concerning this situation, and I feel that the answers about the same problem but in the middle of a sentence do not apply here. Do Americans remove the "t" in "wanted"?

How to re-download Lion to create a VMWare Fusion 4 virtual machine? I have a MacBook with Lion installed.  I bought VMWare Fusion 4 because I want to create a Lion VM.  As far as I can tell I need to point VMWare to the Lion installer that is downloaded from the App Store, but that file deleted itself after Lion was installed.  How do I re-download the Lion installer (and keep it around) to create a VMWare Fusion 4 virtual machine?
