in C#  I am trying to get both the URLs and the InnerTexts from a text file, I don't have access to a DOM object on the device (only a text file) I am using so have only RegEx to use.  &lt;a href="/LinkClick.aspx?fileticket=a random text string"&gt;I want this text&lt;/a&gt;   I would need all these sets throughout the text file:  URL = /LinkClick.aspx?fileticket=a random text string TITLE = I want this text
Im trying to craft a regex that only returns &lt;link&gt; tag hrefs  Why does this regex return all hrefs including &lt;a hrefs?       (?&lt;=&lt;link\s+.*?)href\s*=\s*[\'\"][^\'\"]+        &lt;link rel="stylesheet" rev="stylesheet"      href="idlecore-tidied.css?T_2_5_0_228" media="screen">     &lt;a href="anotherurl">Slash Boxes&lt;/a>   thank you
Mirrored object not symmetrical I am trying to mirror an object and the original is symmetrical along all axis, but when I attempt to mirror across the y axis, the mirrored side is tilted to a different angle. Cutting features to do opposite of clipping in ArcGIS Desktop? What´s the easiest/smartest way of getting the opposite output of the clipping tool?   I just need the area of feature A1 which is not covered by feature A2 in a new Layer/File.  Now, I get the result by union´ing both features and deleting the "wrong" parts by hand.  I'm using ArcGIS Desktop 10. Browsing the internet from the command line I've a friend that booked a round-trip journey. He booked A-to-B and B-to-A. Somehow he needed to be earlier at location B, so he took a train and did not take the flight from A to B.  When he went to the airport to take the "back home" flight (B-to-A), he was informed that his ticket was canceled because he did not take the A-to-B flight. They canceled the ticket and sold it to someone else.  Is this normal? The company said it was their right to do so, and he could not get the flight back. The company was Iberia. What is the difference between Θ(n) and O(n)? Looking for illustrator script to swap all objects with another I have a map with small circles for over 200 cities. I need to change all of the circles into map pins. Is there a way to do this? I think it's a script maybe.   I know how to select all objects of the same appearance and give them a new graphic style but that will only let me change the color, stroke, etc. not replace with a new shape. Is it possible for test error to be lower than training error Is it possible to have test error lower than training error?  I have a classification problem with 2000 samples, 500 of which are positives, 1500 are negatives. I split my data into 70% training data, 30% test data.  Run random forest with 200 estimators and cv=10. I did this several times and compared the recall and precision score and notice the scores for my test set is significantly better. Is this possible? A coworker and I are locked in a debate over the value of SEO keywords in the URL of a page. She wants to change all the filenames of the HTML pages of a fencing company so they look like residential-home-chicago.html, contact-chicago-contractor.html, and so on. She is convinced that because Google highlights keywords in URLs in search results, that means that putting keywords here is more valuable.  My position is that these do not improve SEO, since Google doesn't seem to give keywords in the URL any more weight than keywords in the body of the page, and . In the meantime, they make it harder for me to find the pages I want when its time to edit them, and the site as a whole looks cheap and spammy.   suggests to me that yes, keywords in URLs are useful, but not superior, and that they are more useful for human readability than search engine rankings.  I'm looking for authoritative sources that support either position, not blog articles from SEO optimization companies trying to promote themselves. Can I ask a postdoc who has closely supervised my research to write me a letter of recommendation?

I'm calling a function in Python which I know may stall and force me to restart the script.   How do I call the function or what do I wrap it in so that if it takes longer than 5 seconds the script cancels it and does something else? I have an external hard drive and I did something which I shouldn't have done, and I am annoyed that many files are prompting me about Administrator permissions to move a folder.  They are regular files.  How do I reset all the permission on the external hard drive? Is it possible to embed a scrollable frame inside a PDF? (This is an end-of-year crazy question)   Is it possible to embed a (scrollable) frame or a PDF inside a PDF? If so, how to do it in (pdf)LaTeX?  This is something pretty common in HTML (see for example ). Here it is a webpage with PDF frames   Here it is a fake screenshot so you get the idea.  Portable and non-portable (e.g. only-Acrobat) answers are welcomed.     Example of a down arrow below a frame. The up arrow can be on top of the frame and the triangles point up. I’m writing a document in the latex and it contains some BNF grammar noations in several places of the documents. (I used verbatim package in order to write these BNF grammar notations)  Now I want to add a new section to the document that shows name of all grammar notation and their page numbers. This should be similar to “List of Figures” page.  I’m new to Latex and your help will be very helpful for me.  Thanks I am new to Ubuntu and Linux in general.  I created a dual boot OS on my laptop (Windows 10 and Ubuntu).    Typing: sudo apt-get install python3-tk (or even python-tk) didn't work. Trying to install the python3-dev or python-devel (no luck). Downloading Tcl and Tk to manually install.   In Windows 10 Bash Subsystem the Tk and Tcl are already included, so I thought Ubuntu already had it.  But, I want to use my Ubuntu desktop to develop Python GUI apps.   So, how can I install the Tcl/Tk to be use in Python 3.5 for GUI development?   I loaded Python 3.5.2 fine but need the GUI modules enabled.  The code to test that Tk is working is:      Type python3    Type:     import tkinter    tkinter._test()  Result: a GUI pop-up displaying This is a Tcl/Tk version.. See permissions for new files on a given directory I don't understand how my Linux machine is operating on new files.   I have an Amazon Linux AMI (RHEL based distro) and when I execute umask I get 0002, so I get whenever I create new stuff other users won't get write access.  But then I go to my home directory and I type:  $ mkdir myDir $ touch myDir/myFile $ ls -l | grep myDir   and I get  drwxrwxr-x 2 myself myself 4096 May 11 22:37 myDir   and for the folder:  $ ls -l myDir -rw-rw-r-- 1 myself myself 0 May 11 22:37 myFile   So apparently there's more going on there then my umask, since myFile permissions are more restrictive than just write protection.  Digging deeper, if I try:  $ sudo touch /var/run/myPidFile.pid $ ls -l /var/run/ | grep myPidFile.pid -rw-r--r-- 1 root    root       0 May 11 22:42 myPidFile.pid   So myPidFile.pid gets a much more restrictive default permission, under /var/run then myFile gets under my home folder.  We could blame the root umask but if I run umask under root I get 0022 which is indeed more restrictive then my user's 0002 umask but still doesn't explain how the execution bit permission isn't set.  So how can I understand a folder's default permission on Linux? Which badges do not cause a notification for experienced users? Yesterday, I have received two : Revival, and Self-Learner. However I was only notified of the Revival badge, because apparently the Self-Learner badge is not considered "".  What badges have their notification suppressed if the user has a 200-rep account somewhere on the Stack Exchange network, i.e. they won't trigger a new item in our achievements dialog? Passing named arguments to shell scripts Is there any easy way to pass (receive) named parameters to a shell script?  For example,   my_script -p_out '/some/path' -arg_1 '5'   And inside my_script.sh receive them as:  # I believe this notation does not work, but is there anything close to it? p_out=$ARGUMENTS['p_out'] arg1=$ARGUMENTS['arg_1']  printf "The Argument p_out is %s" "$p_out" printf "The Argument arg_1 is %s" "$arg1"   Is this possible in Bash or Zsh? How do I change my Chrome language back to English?
