Command to italicize text with slanted numbers I often find myself adding a lot of \textsl{} around inside \emph{} or \textit{} blocks because I find italicized digits to look too "showoffy" and "baroque" and to hinder legibility (I'm using $$ when the number has a mathematical sense, but this situation occurs in less technical texts like CVs, and such.).  Could someone help me write a renewcommand to automate this, or better, a single low level command that makes \emph, \itshape, \textit and friends choose slanted over italic for numbers? I'm not too familiar with the low level latex font selection system nor with a way to detect digits from regular letters.  Edit: MWE of what I need and what I want to avoid  \documentclass{article} \begin{document} He thought: '\emph{Why 1234567890 apples?}' then he realized '\emph{ah yes, he has \textsl{1234567890} childs}' \end{document}   gives:   I find the italicized version (first one) of 2,3,4 and 7 to look especially bad. Sass Interpolation of Mixin, Function, and Variable names xslt processing on select attribute on apply-templates illustrates drag coefficients for several shapes:    It is generally accepted that some variation of the teardrop/airfoil shape has the lowest drag coefficient.  I was wondering what shape has the highest drag coefficient.  The image suggests that it is a flat plate, and that would seem to be an intuitively correct answer, but is that correct?  Is there some other shape (perhaps with a concave front or back relative to motion) that has an even higher drag coefficient? Expected number of hamiltonian paths in a tournament The following theorem is from Alon&amp;Spencer's The probabilistic method, in the beginning of chapter 2:  Theorem 2.1.1: There is a tournament $T$ with $n$ vertices and at least $\frac{n!}{2^{n-1}}$ Hamiltonian paths.  Briefly the theorem is proved by looking at $X_\sigma$ the indicator random variable for a permutation $\sigma$ giving a Hamiltonian path, that is, satisfying $(\sigma(i),\sigma(i+1))\in T$ for $1\leq i \lt n$. Then   $\sum \mathbb{E}\left[X_\sigma\right] = \frac{n!}{2^{n-1}}$.  I don't understand where did this value ($\frac{n!}{2^{n-1}}$) came from! could someone explain it please? Using the validation data I'm unclear on the exact process of using the validation data.  Let's say that I fit my neural network model and adjust hyperparameters using the training set and validation set. Do I then evaluate the test set on this model? Or do I recombine the validation and training sets and fit a fresh model with the hyperparameters that I found during the validation phase, and then evaluate on the test data? I have seen a number of different notebooks and examples that do both ways.  Surely, once I've found my hyperparameters, it makes sense to fit a fresh model using the full training set (recombined with validation set), since the validation loss has no effect on the weights. How do I replace the *first instance* of a string in .NET? How can I get an email message's text content using Python? I've used recursion quite a lot on my many years of programming to solve simple problems, but I'm fully aware that sometimes you need iteration due to memory/speed problems.  So, sometime in the very far past I went to try and find if there existed any "pattern" or text-book way of transforming a common recursion approach to iteration and found nothing. Or at least nothing that I can remember it would help.   Are there general rules? Is there a "pattern"? I live &amp; work in the UK.  Having pretty much exhausted all of the avenues I can find for saving (none of which have great returns anyway at the moment, obviously), I have recently started looking to buy my first house.  I have a reasonable sum saved up for a deposit, but I'm wondering what to do with that in the mean time, as a fair amount of it is not currently earning any interest. For the moment, I have put any surplus, that I'm not earning interest on into premium bonds, just in the off-chance that I win something with it, but this is obviously more of a lottery than an investment, and I'm not 'expecting' to win anything noteworthy with it.  Ideally, I would like to buy a house within the next year or so, so investing in the stock market is not really an option, as I understand the commonly accepted advice is that you invest with a minimum 5 year horizon.  What other options do I have for any surplus cash while I look for a house? Are there any non-decreasing securities on the stock market? Are there any securities traded on the stock market (i.e. ETPs) that never decrease in value?    As an aside (in case anyone mentions bonds):  I'm aware there's ETFs for AAA-rated government bonds, but even these dip significantly.  For example, the  has dipped by 9% in a 85-day period before (21/08/2016 to 13/11/2016). Unable to lock the administration directory (/var/lib/dpkg/) is another process using it?

How can I fix this? How do I include lines in resolv.conf that won't get lost on reboot? Syntax error on print with Python 3 Clicking on a notification on Android app opens an empty feed When I receive a message on an SE post, I get a notification like this:    If I double tap this notification, the SE application opens, but my feed is empty approximately half the time. It looks like this:    If I refresh the feed (slide from the top), the feed does refresh and shows the new notification.   The notification, above, leads to  comment.  I haven't figured out the pattern yet, but this occurs roughly half the time I open a notification. It's occurred for chat messages, comments and answers - but not consistently. I have received notifications for the same post (for example, the two comments after the one linked above) that do not show an empty feed. But, a chat message barely 10 minutes later will show the empty feed again.  I am utilizing the beta app - version 1.0.72 on Android 5.0.1. What was the joke that Geordi told Data in TNG: "Encounter at Farpoint"? states:     Apparently at some point during this mission, Geordi La Forge told Data a joke, which the humorless android did not "get" until years later, when he activated his emotion chip during the events of Star Trek: Generations.    Is it known what the joke is? I made chili and it's too hot! If I cook it longer will the heat calm down? Currently, once an edit by a user without full edit privilege is suggested, it can be either approved or rejected.  There is a known edge case that cause suggested edits to get auto rejected: (aka edit conflict)   User with full edit privilege click "edit" and start typing. Let's name this user Joe. Since the user from previous step did not yet send the edit, users without full edit privilege can still click the "edit" as well, oblivious to the fact someone else is editing the same post in those very seconds. Such user click "edit" too and start typing. Let's name this user Kenny. Kenny is faster than Joe: he send his edit first, creating new suggested edit. Joe is still typing. Joe finally done typing. He send his edit to its merry way oblivious to the consequences. As result of the full edit made by Joe, Kenny's suggested edit is kicked away and rejected. Boom.   This is all known and reported many times.  where the user got it hard with at least two auto rejections in short period of time. Some concrete examples: , , .  For edge case, it became pretty thick edge. This is not just minor hassle: enough rejections, and the user is banned from suggesting for a whole week: and remember we're talking here about good edits made by good users. The above used to count for the ban, but . Thanks Gilles for requesting such a change!   I know it was already suggested to lock edits and similar solutions, but I suggest whole different approach: instead of auto rejecting the suggested edit, dismiss it, i.e. cancel it like it never existed same way a bounty can be revoked by moderator.  In the edit suggestion page it will show "Dismissed" instead of Approved or Rejected maybe with a tooltip explaining what caused this. This will soften the blow from those edge cases, taking the edge out of them. :) How do I find out the number, type, resolution &amp; refresh rate of additional monitors I can attach to my MacBook or MacBook Pro?  This is an attempt at a canonical QA, as per the Meta QA -   to try prevent the myriad "same but different" questions we get on every possible combination of computers, cable &amp; monitors There are perfectly good resources out there that Ask Different should not have to duplicate the efforts of. Any nice, stable ways to keep a window 'Always on top' on the Mac?
