How to use AT commands in Android by 'root' the phone We have various Android devices from Spike, Samsung, Micromax, etc. How can we issue AT commands from Android to the modem? We searched in Google Play but did not find any app related to this.   suggests:     [F]irst you have to root the phone...`    How can we do this? Why don't std::algorithms work directly on containers as well? How do you retrieve items from a dictionary in the order that they're inserted? Is it possible to retrieve items from a Python dictionary in the order that they were inserted? When I open the terminal on my Mac, this is what it shows:  australia:~ rod$   I don't live in Australia, don't have anything to do with Australia, nor have ever setup terminal as Australia.   Where does that name come from, why is it there, what does it mean and how do I change it (or should I even change it at all)? Wifi not working (Intel) on HP Spectre x360 13 Random test data: How to do it right? Several months ago I started an experiment in test automation. Each test, before it starts, picks up random test data. For instance, when my test requires a user with administration privileges, I draw a random account and then I from a group of admin users for this account I draw a random admin user.  The reason for using random test data was two-fold:    First, when we were using static, i.e., hard-coded test data, sometimes tests started to fail, because test data no longer existed in DB, e.g., a user has been removed from the database (we're having production dump in our test DB, so I guess the user has been deleted in production). When we started to find such users at runtime, the problem disappeared.  Second problem was that it was not really clear why certain test data were used for a certain test. We have inherited tests from the other team and couldn't understand their intentions behind, for instance, using user "xyz@awesome.com". By writing queries to find data, we started to explicitly state what type of test data we want, e.g., that we want a user with administration privileges.   While my approach solved both problems, it introduced also some new issues:   Tests occasionally fail, because they pick up wrong test data. This is because queries are sometimes incorrect. For instance, once a test drawn a random account that had no administrators at all. Good thing about that is that this way I keep learning new things about the system under tests, e.g., that there must be business reasons to have accounts without administrators. Test setup becomes more and more complex, as queries start to grow and thus tests seems now a bit more complex to understand.   I was also hoping to increase coverage and find more bugs by using random test data just like it is done in fuzz testing. Instead, I mostly found bugs in my test and learned how little I know about the system under test. Finally, ROI doesn't seem big. Before the change there was a cost of maintaining static test data (updating test data if they were outdates). Now I have to maintain complex queries when the test takes "wrong" test data and this tends to occur more often than outdating of static test data previously.  I wonder whether using random test data really makes sense and how to do it right? How does the coin limit work? The new gym update , including a limit of 50 coins earned per day. How does this limit work? Is each pokemon limited to accruing 50 coins per day? Are all my pokemon limited to a collective 50 per day? My teammates keep feeding my Dragonite and she has been at the gym for almost a week; will she return with 50 coins for each day she was there? Fewer than 50 for the days I had other pokemon in the gym? Or will she accumulate vast sums of coins over the week, but only deliver me 50 (or fewer) when she comes back based on what I have collected from returning pokemon that day? Why can't photons have a mass? Could you explain this to me in a short and mathematical way? This example illustrates some conflict between xelatex and natbib- and footnote-generated superscripts.  The semi-colon between distinct citations is not typeset as a superscript, nor is the dagger.  The asterisk, however, looks fine to me.  Any suggestion on how to make these auto-generated superscripts look more normal?   Update Mostly fixed, see second screenshot below.  Update 2 Fully fixed!

Thanks Can we make it more plain to recruiters that we're not open to relocation? The preference for being open to relocation is a checkbox, and if you don't check it, nothing about relocation shows up in your profile.  Evidently recruiters can't understand that a lack of "I am open to relocation" is the same thing as "I am not open to relocation", and so every single contact I've gotten through Careers is for a job that I would have to relocate for.  Can we make it more obvious to the recruiters (especially ones from Amazon) that we have not checked that box on purpose? How do single photons travel from here to there I know there have been similar questions but I'm still unclear what the overall consensus is. (1) I assumed and have read that photons travel in straight lines unless deflected by gravity but there are conflicting theories. (2) I have heard that single photons takes every possible path but that makes no sense. Why would a single photon traveling from here to the moon go to every other place in the universe along the way.  (3) I can understand a single photon traveling as a particle or packet of energy but I have a hard time understanding a single photon traveling as a wave. I have never understood any attempts to answer this.  (4) Does a single photon have a frequency and what causes the frequency? If not then how does it have energy? I have many questions about single photons and their frequency. For any two sets $A,B$ , $|A|\leq|B|$ or $|B|\leq|A|$ Let $A,B$ be any two sets. I really think that the statement $|A|\leq|B|$ or $|B|\leq|A|$ is true. Formally:     $$\forall A\forall B[\,|A|\leq|B| \lor\ |B|\leq|A|\,]$$   If this statement is true, what is the proof ? Boundary of Ball of radius R has zero measure Paperback novel about a man who kills a birdlike alien on his balcony with a watering can Reference label with included file and relaxed clearpage I am running into a rather weird error that apparently originates from the combination of \include, \let\clearpage\relax and a referenced label after a page break.  In this particular example, the label mylabel defined in the listing cannot be referenced anymore when the reference and the label are close enough to a page break.  The MWE consists of two files, the main-file and an included file. I am using the \let\clearpage\relax command to . The error does not occur if the file is \input instead of \included.  \documentclass[11pt,twoside]{book} %  \usepackage[utf8]{inputenc} % Enoding \usepackage[english]{babel} % Language \usepackage{listings} \usepackage{forloop}  \begin{document} \begingroup \let\clearpage\relax  \include{includedfile} % changing include for input would work  \endgroup \end{document}   Included file:   \newcounter{ct} \forloop{ct}{1}{\value{ct} &lt; 40}% {%     .\\ }  Listing \ref{mylabel}.  \begin{lstlisting}[caption=somecaption, label=mylabel] some code; \end{lstlisting}   Running this example will have an output where the label cannot be referenced (even after multiple runs):    Now, one solution is to use \input as mentioned earlier but I am rather interested in why this happens. Does the \clearpage command fulfil an important function for references to work? And can the error be avoided without removing \let\clearpage\relax while using \include?  EDIT: I just found  with the same issue (though it does not have a definite answer).
