Why did the SE team unfeature the recent announcement about font changes? I noticed that  about the change of fonts was once featured in Meta, but now, it seems that it is no longer featured. How long do Meta posts stay featured?  I'm not asking about the technical reason why the post is no longer featured, which is what  is asking about. Instead, what I'm asking is why the SE team chose to remove the  tag from the post and when they remove the tag from posts. Those are not answered there.
When and why is the [featured] tag removed by the Community user? I've found that the Meta (moderator only) tag  is automatically  by the  user. So, I want to know when and why is the tag  is removed by this user?  Is there any mechanism for this removal or is there simply a specified time period after which the  is automatically removed by the Community user?
I have a Linux CentOS server, the OS+packages used around 5GB. Then, I transferred 97GB data from a Windows server to two folders on this Linux server, after calculated the disk usage, I see the total size of the two folders is larger than the disk used size.  Run du -sh on each folder, one use 50GB, the other one use 47GB  But run df -h, the used space is 96GB. (50GB + 47GB + 5GB) > 96GB  Is there any problem? Those two folders contain lots of files (1 million+). Thanks. Consciousness is an electrical and chemical interaction in the brain, caused by neurons firing and chemical interactions. How does a mechanical "force" cause this to stop working?  i.e. How does a mechanical action (such as a punch to the head) cause this electrical/chemical system to stop working (leading to unconsciousness)? One click to site meta? Right now from a main site, it takes TWO CLICKS to get to http://meta.SITE.stackexchange.com/ - ONE!  TWO!

I currently have an ec2 &quot;t2.nano&quot; instance up and running. I would like to switch to a &quot;t2.micro&quot;. In order to do that, I need to stop the instance. But I would lose my IPv4 address in the process. And I do not want that (because I have several ssh tunnels up and running from rasps in the wild that are currently hard coded to connect to this IPv4 address). I decided to create an Elastic IP address. But I understand that by creating an Elastic IP address and assigning it to my current ec2 instance, I would lose my current IPv4 address too. Is it possible to create an Elastic IP address from the current IPv4 address of my ec2 instance? If so, how can I do this operation? When Cantor's Intersection theorem won't work with closed sets Give an example to show that Cantor's Intersection Theorem would not be true if compact sets were replaced by closed sets.    Compact set is closed and bounded, so what I'm going to find is something that is closed but not bounded.  By the Cantor theorem, which says that a decreasing sequence of non-empty compact subset will have a non-empty intersection.  What I was trying to approach is how two sets just "touched" and as if they have not bounded, two sets "touched" nothing. But I cant give an example for that Schengen Visa Refusal: Justification for the purpose and conditions of the intended stay was not provided Schengen refusal formulae can be difficult to understand sometimes.    When an applicant receives a refusal with "Justification for the purpose and conditions of the intended stay was not provided", what does it mean? Need to reset the value of sequence in Oracle Equation of motion of a free particle We know that the equation of motion of particle can be derived from the respective action. But in the book I am reading, the author is saying:     ... timelike worldline of a massive particle is parametrised by proper time, $x^a=x^a(\tau)$. The velocity (tangent) vector is $u^a \equiv \dot{x}^a(\tau)$. This is normalised as $u^au_a =-c^2$.   How can one derive e.o.m? Can I insert elements to the beginning of an element using .appendChild()? If the user selects an option in a dropdown box, there must be added a label and a textbox. Using appendChild, these elements get added to the end of the container.  var newFreeformLabel = document.createElement('label'); newFreeformLabel.innerHTML = 'Omschrijving:';  var newFreeformField = document.createElement('input'); newFreeformField.className = 'textfield'; newFreeformField.name = 'factuur_orderregel[]';  var newFreeformSpacer = document.createElement('div'); newFreeformSpacer.className = 'spacer';  container.appendChild(newFreeformLabel); container.appendChild(newFreeformField); container.appendChild(newFreeformSpacer);   The issue is that these elements should be inserted at the beginning of container, not at the end.  Is there a solution to this in PrototypeJS? SIB 2009, Problem #2 Let $f(x)$ be a continuous function, whose first and second derivatives are continuous on $[0,2π]$ and $f&#39;&#39;(x)≥0\:\:∀\:x∈[0,2π]$.

Is there a bulletproof way to know a file has been successfully decrypted? I am wondering whether there is a bulletproof way to know if one is successful in decrypting a file.   As an example, say I encrypt a text file and protect it with a 3 letter password. I use brute force to decrypt it, but two different passwords lead to a file that contains English intelligible text. Is there a way for me to know which one is the original one? In other words, is there an infallible way to know I've entered the password correctly? Difference between shadowing and overriding in C#? What would be the sum of the following series?  $$\sum_{n=1}^{\infty} \frac{1}{n \cdot 2^n}$$  Thanks I expect to be working on a web application within the next several months and I'd like to "shoehorn" a Spanish language version of the site. If a large enough number of Spanish language users begin using the site we'll likely hire a professional translator (or at least recruit someone who actually knows the language), but in the meantime is there a good cheat sheet I can use for common UX keywords, like "OK", "Submit", "Cancel", "Delete" and "Save"?  I know I could use an online translator, but I'm concerned the translator would not pick up on context (thus giving me a Spanish word meaning something closer to "Take" for "Accept" or "Surrender" for "Submit", etc.)  I'm not looking for a 100% solution, just something to give me the bulk of the keywords until there's enough reason to hire a real translator. This site will be in a beta development phase for a long time, I think, so we're not expecting a huge user base to start things off. How can I remove fonts that I never use, from libreoffice and linux in general? There are a lot of extra fonts that all seem to look alike and just annoy me in the drop down list. Is there anyway I can erase them from the system? I've been thinking about switching to Ubuntu full time, but there are still some programs left behind that I haven't found any equivalent to yet. Does anyone know of a music player similar to Foobar2000 (I've read it doesn't handle well in WINE)? Can misused Schema.org hurt SEO? I've inherited a site where I noticed that    there is an excessive use of Schema.org in all navigation elements pages describing products are marked as itemtype="http://schema.org/CreativeWork"   So I'm wondering if these tags are sending the wrong message and not truly optimized. I realize that the nav (1) is done in some themes, but I'm more worried about (2). Can it be a hit SEO-wise to mislabel pages instead of products? Prepositional Phrase - confused - at or in
