What's the difference about /t̬/ and /d/? Creating a new DOM element from an HTML string using built-in DOM methods or Prototype What should I do when my neural network doesn't generalize well? I'm training a neural network and the training loss decreases, but the validation loss doesn't, or it decreases much less than what I would expect, based on references or experiments with very similar architectures and data. How can I fix this?    As for question        to which this question is inspired, the question is intentionally left general so that other questions about how to reduce the generalization error of a neural network down to a level which has been proved to be attainable, can be closed as duplicates of this one.  See also dedicated thread on Meta: Is it two-third or two-thirds? Is it two-third or two-thirds? If both are correct, how does their usage differ? Two diagrams side by side I am trying to put two feynman diagrams side by side, but they get displayed below eachother. I am using feynmf and subfloat.

How can I remove it completely?  Under configuration -&gt; completion nothing is checked. From where do I remove the auto-completion of these? jQuery call function from a string How to upgrade to GNOME 3.30 on Ubuntu 18.04.1 I think sometimes there is a need to post question as anonymous, reason being to avoid linking content of a question with the identity of the questioner. This may not be so evident or required on technical sites like stackoverflow.com but sometimes is a necessity on sites like  or maybe in future depression.stackexchange.com  On such sites user may not want to link his identity to some questions where he may detail about his being over-weight or skinny or maybe some other attribute which he may like to keep private and avoid making his concerns public, but still want to ask a question with valid data.  I am not suggesting that user asking question should not be registered or not responsible for content. I think all down-votes or up-votes should still be attributed to user, but this way most users would not suffer , and reputation could even be used for a bounty. The only change should be that while asking question a valid registered user can hide his identity (the whole user signature block/user card and the reputation should be replaced by "identity-hidden") and that question should not be listed in his public profile.  Anyway identity of questioner doesn't add much value to question. If we think such anonymous question may reduce social nature of Stack Exchange sites, and maybe majority of questions will become anonymous we can curb that by putting a daily or monthly limit per user or put a price of say 50 reputation per anonymous question.  PS: I don't think this is duplicate of        because motive for question and reason for feature request are different, and I propose a different solution too, because creating another account for asking such questions has many problems which having a single account doesn't have    I don't have to manage other account If I keep single account I still may want to keep my details to be linked to my non-anonymous questions I may want to use reputations I earned as bounty for anonymous questions    also allows anonymous questions and may be we can take some hint from there. Evolution of the Redundancy of the Genetic Code Add 1Password extensions support to the SE iOS app Please implement the URL scheme to call 1Password for password lookups on the iOS app.   a URL scheme for switching to 1Password to search item titles for a custom term, usually a service name like “twitter” or “evernote”. This speeds up the process for the user so they can copy something like their password and get back to your app  That will ease sign up speed using long, complicated or unmemorable passwords for many users of both apps. In the two years since the above blog was published there are now updated instructions for implementation and code on github: As we all know that Kurama's chakra is of the healing nature type. This is known from many mentions about it in the wiki page of .  My question is, what is the nature type of the chakra of the other Tailed beasts?  Note: This is my thinking why there should have been a nature type to each of the tailed beasts.   As we all know that when Rikudō Sennin was about to die, he split his powers among his two sons (the older son inherited his powerful chakra and spiritual energy, and the younger son inherited his powerful life force and physical energy). Similarly, when creating the nine tailed beasts from the Shinju, he must have split the chakra based on their nature so that each tailed beast had a unique natured chakra.  Any insight on this would be very much welcomed. Is it possible to follow a user automatically? I've been looking around and I can't seem to find an automatic (i.e. buzz- or Twitter-like) way to follow users inside Stack Exchange. Why haven't the developers added such a feature? It could help beginner users follow other beginners with the same interests. We would be able to learn from each others' questions and pitfalls. Also, it would reduce double posting. Is the universe finite or infinite? I thought the universe was finite, but then I read this:    And they seem to assume it is infinite. So which is it? Since I upgraded to the latest version of Ubuntu, I cannot install the Java OpenJDK package needed to compile Android custom ROMs. When I run sudo apt-get install openjdk-7-jdk, the following error appears:  Reading package lists... Done Building dependency tree        Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation:  The following packages have unmet dependencies:  openjdk-7-jdk :  Depends: openjdk-7-jre (= 7u51-2.4.6-1ubuntu4) E: Unable to correct  problems, you have held broken packages.   How do I fix this problem? ffmpeg settings for converting still images to video for archival I need to convert a set of still images (static cameras pointed at a road) to a video.  I have considered video codecs such as Theora, H.264, VP8, VP9, HEVC, Snow.   The video should have a minimum size with the maximum image quality. Now, from all available command-line arguments, I'm using framerate (fps), b:v (bitrate) and s (width*height). Also, for H.264 and HEVC there are -crf and -preset.  What other command-line arguments can be useful to achieve what I'm after? In ffmpeg dozens of command-line arguments and parsing each can take a long time. Wired connection not working Ubuntu 12.04 In Knuth's book "The Art Of Computer Programming Vol.1" there is a description about Euclid's algorithm to find the greatest common divisor of m and n.   And there is a phrase.     $m = qn+r$.  If $r = 0$, then $m$ is a multiple of $n$, and clearly in such a case $n$ is the greatest common divisor of $m$ and $n$. If $r \neq 0$, note that any number which divides both $m$ and $n$ must divide $m -qn =r$ , and any number which divides both $n$ and $r$ must divide $qn+r =m$.   I don't understand why any divisor of $m$ and $n$ must divide $m-qn =r$.
