Today I  on StackOverflow, which was accepted and upvoted 10 times. I received only a Nice Answer badge, while I was expecting an Enlightened one, as well. My answer was the first one for the question, also.  Do I miss something about the Enlightened badge rules ?
Today I've got 10 upvotes for an answer. Answer was a first answer in the question. I got an Nice Answer badge for this, but no Enlightened badge.  Shouldn't I get both?  is my answer :)
Does there currently exist a free online service that accepts a file, hashes it, takes an authoritatively chosen timestamp (from one or more time services), signs these and sends this signed message back? E.g. a digital notary, but only with regards to the timestamp and not the validity of the content as legal notaries might be obligated to guarantee.  Such a service might have an extremely simple API: Simply wget http://service/&lt;checksum&gt; and receive a signed message containing one or more timestamps and the checksum. The emphasis would be on the type of authority who might make such a service.  Edit: Although the original question did not emphasise the following, the Bitcoin-based timestamping services provided below do not rely on one authority, but rather the entire Bitcoin network. They can be seen as tamper-proof and verifiable without the help of the service that helped you sign it! How to enable automatic update in wordpress running on IIS7 and Windows 2008? I have a dedicated server using Windows 2008 and IIS7 running 5 blogs with Wordpress. I can't use the autoupdate feature of the wordpress neither the automatic plugin instalation.  I believe I must set writing permissions in some temporary folder, the question is which one. Do you have any idea? Calculate mean of ordinal variable I've read in a number of places that calculating the mean of an ordinal variable is inappropriate. I'm trying to get an intuition for why it might be inappropriate. I think it is because, in general, an ordinal variable is not normally distributed and so calculating the mean will give an inaccurate representation. Could somebody give more detailed reasoning for why calculating the mean of an ordinal variable might be inappropriate? Can I get UAC prompt for user from batch file? Can I get UAC prompt for user from batch file?  For example I need put some keys to registry under CurrentControlSet from batch file by     reg import path\to\my.reg   PS. runas is not a solution as my customers uses different Windows localisation and I can not guess which name used for Administrator account (this can be Администратор)...  And script don't know administrator password.  And UAC dialog box does not require password entering... I am a newbie in linux. I wanted to install ubuntu to my desktop. I currently have two partitions, Windows 8 in installed on one, and i have some important files in another partition. While installing ubuntu, if I chose "Replace Windows 8 with Ubuntu", do I lose the other partition too?   And are there other ways to leave the other partition as it is, and install ubuntu in the partition  where windows was installed. Screensaver with active desktop I am running XP and im looking for a screensaver that does not change the desktop. I.e when the screensaver is active, i want to be able to see my desktop as it is and any changes on the desktop to be visible. Only if i touch the mouse should the login prompt be displayed to inactive the screensave.   For example, i am usually either working on my desktop or laptop. On my desktop i have an applicaiotn running that is showing me stock quotes from the stock exchange. Everytime the screensaver activates i have to touch the mouse to bring the screen back.   What i want to be able to do, is to be working on my laptop and at any time look at the numbers on my desktop without the screensaver interfering. I want the screensaver to be active but its only job is to ask me to enter the password to unlock the screen. I should still be able to see teh stock prices as tehy are changing even while the screensaver is active.   Basicly is it possible to see the desktop while the screensaver is active?   Thanks Is there a way to disable certain Windows 7 keyboard shortcuts?  Specifically, in this case, I want to disable Alt+Space and WinKey+Space.

How to remove the association between two Gmail accounts? I want to remove that other account. Both of them are Gmail accounts. How could I do? Why does signing on to one site not sign me on to all of them? I've seen this question asked 3 times, but in none of those threads did I find a satisfactory answer.  I'm not asking about reputation: it makes sense that different sites should have different reputations.  However, consider the StackExchange drop-down menu at the top left of the screen.  When looking through the "Hot questions", the links are often to sister websites of StackExchange (programmers.stackexchange i.e.).  It doesn't make sense to me that if I go to one of those sister sites, I'm no longer logged in.  I feel like it's counterintuitive to click a link to go answer a question, only to find that you can't answer that question until you log in.  What is the reason for this?  Is there an option to do as I'm suggesting? Dual boot windows 8 and Ubuntu with Windows 8 Boot manager How to help a toddler overcome the fear of water on head? I've just gotten started with Nielsen and Chuang's text, and I'm a little stuck. They mention that theoretically, it would be possible to store an infinite amount of information in the state of a single qubit. I'm not sure I completely comprehend this.    Here's how I rationalized it: You take all the information you want to store, put it in binary form, and make it the real component of $\alpha $ or $\beta$ (the coefficients of the computational basis states).   Now I'm not sure if I've understood it right, but since it's still fuzzy in my head it would be great to get some kind of ELI5 explanation or possibly a more detailed picture of how this would, even theoretically, be possible.    Apologies if the question doesn't meet standards. I'm new to the forum and would be open to feedback regarding asking questions or answering them. Right-click on Touchpad not working after update to 18.04 LTS I have a Lenovo Yoga 910-13IKB. I was running Ubuntu 17.10 with no issues. I upgraded to 18.04 LTS and now my right-click on my touchpad does not register. I can only left-click.  I already tried the steps listed , but they did not fix the issue.  Does anyone know how to fix this?  Thanks. Most commented post should be the first post in the blog WordPress default setting is, most recent post is the first post of the blog.

I have sucessfully installed AniMove by activating experimental plugins (yay! thanks gis.stackexchange). But I can't find it in Qgis! Yes I have activated it. Where is it? Is this a common bug? I searched for it the toolbox, I looked up the names of the several single tools based on this  and only found "Kernel Density", which is filed under SAGA. But I don't have SAGA installed (and don't know if I need to?) I'm currently going through notes on a physics course and I'm having trouble understanding the difference between a tensor, a vector, and a matrix. I know that a vector is a kind of tensor and that a matrix is also a form of tensor, but what I'm having trouble understanding is how they differ, and how a vector is related to a matrix. I just want to write a script which changes my directory.  I put the below commands in the file /home/alex/pathABC  #!/bin/sh cd /home/alex/Documents/A/B/C echo HelloWorld   I did   chmod +x pathABC   In the Terminal, while in /home/alex, I ran ./pathABC, but the output is just HelloWorld and the current directory is not changed.  So what is wrong?
