Travelling into heathrow in April , Have an IPhone 6 4g how much will a sim card cost,  pay as you go. Data calls and text. will it have a uk tel number?
Next month I am traveling to country X, where I would need Y minutes of calls, Z text messages and most importantly Q megabytes of data. How can I find the cheapest/most reliable SIM card for my needs?
Not able to calculate sum of multiple column where file data in different format .csv I have a scenario where i want to calculate sum of column   SAL|CAL|TAG|VAL 12.11"|"1.1"|"2.1"|"1.1 13.11"|"1.1"|"2.2"|"2.2 14.11"|"1.1"|"2.4"|"2.4   My below code not giving output giving output as 0.00  I need output for this column CAL VAL  awk -F'|' '{T+=$2} END { printf "%.2f\n", T }' demo.txt   output :  6.7 5.7 OS is openSUSE 12.1, PostgreSQL - 9.1, PostGIS - 2.0. Postgre/PostGIS are installed from Application:Geo repository.  After recent updates when I try to connect to my database I get the following error:      ERROR:  could not load library "/usr/lib/postgresql91/lib64/postgis-2.0.so":  /usr/lib/postgresql91/lib64/postgis-2.0.so: undefined symbol: pj_get_spheroid_defn   I searched the web for this error (, ) and seems that it may have something to do with ld.so.config (or ldconfig command). But I can't figure out what I have to do in my case. Today, on C.SE, I reviewed some 'Late Answers' and First Posts.  I was not even near my daily vote limit.  And yet, I was given a message that said      comments disabled on deleted / locked posts / reviews   It seems I was not the only one either:   The workaround, of course, was simply to go back and provide the guidance - but was this a design or a bug?  If it is design, why would you want to discourage the feedback? Especially with first posts, there is often a high percentage of 'didn't read the FAQ' usage, which can best be addressed by gently providing guidance. (e.g. "Unfortunately, this doesn't answer the question" or "This reads like a comment" or "This really isn't on-topic here - can I suggest you checkout our [faq]" etc...)  Timely first post guidance goes a long way towards making good users.   If it was a bug, was other functionality silently rolled out? I just can't find a decent (and free) one. What can I use? Loopy integral $\int xe^x\sin(x)$ Read columns from file, then column into an exsisting csv file Essentially, I have a csv file that contain multiple columns, called cols.csv  1,a,100 2,b,200 3,c,300 4,e,400   and I have a new csv file that has one column, called col.csv  f g h i   I want to copy the items in col.csv and append them to the end of each line in cols.csv so that, cols.csv now contains those  1,a,100,f 2,b,200,g 3,c,300,h 4,e,400,i   is that possible at all? i tried join, paste, nothing worked Every real number in $[0,1]$ has a decimal expansion $0.d_1d_2d_3...$, so construct an infinite tree rooted at 0 where each node has branches leading to $\{0,1,2,3,4,5,6,7,8,9\} $, and let each path through the tree represent the successive decimal digits of a real number. To enumerate them, go through the tree breadth-first i.e. layer-by-layer. I get that some spells are "especially swift" to cast and thus have a casting time of "Bonus Action". But is there any reason I couldn't cast such a spell as my Action?   Does it make a difference if the idea is for the one spell to be cast all by itself on a turn or if the desire is to use another Bonus Action (possibly a spell) on the same turn? PS1='$(pwd)' why this works and why is this different from PS1=$(pwd) Why when I enter this command the prompt changes to my directory?  PS1='$(pwd)'   I am using single quotes, which means no interpolation , a.k.a echo '$(pwd)' ——→ $(pwd)  Furthermore, say that we clarified why this works... why is it functioning differently from PS1=$(pwd) ? (no quotes at all)  By different I mean that if I use the quotes then the prompt will keep changing to my current directory as I navigate through the terminal. But if I don't use quotes, then the prompt will always remain the directory that I was in when I first entered the command PS1=$(pwd)  why?

Remove duplicate fields in a given column (after ID check) Process Unicode files with BOM correctly with POSIX tools Using bm with eulervm gives inconsistent ‘’ characters I prefer to use bm package to bold math. However, I noticed that when used with eulervm, this gives inconsistent results for ‘&lt;’ and ‘>’ characters.  I wonder what causes it and can the usage bm be fixed to get proper ‘&lt;’.  \documentclass{article}  \usepackage[utf8]{inputenc} \usepackage[T1]{fontenc}  %\usepackage{amsmath}  \usepackage[euler-digits,euler-hat-accent]{eulervm}  \usepackage{bm}  \begin{document}      \texttt{\hphantom{mathbold}\llap{bm}}: \quad $ 1 + 1 &lt; 3; \quad \bm{1 + 1 &lt; 3} $      \texttt{mathbold}: \quad $ 1 + 1 &lt; 3; \quad \mathbold{1 + 1 &lt; 3} $  \end{document} I am trying to install ia32-libs on Ubuntu 12.04 LTS (x86).
