In the recent process of processing data with the shell, it was found that the read command would replace \ t with a space when reading the data, and \ t discard at the end of the line. Look at the help of Read, find-R can retain the escape character, searched for someone also said can use-r, but my experimental results are even if-R is still still. Unfortunately, data processing with awk should be used. Using \ t as the data field delimiter is often used during data mining, and the default key

Just started to touch the mobile page refactoring, is not very confused how much size should be made? 320, 640 or 720? Do you need to write other sizes to fit different screen sizes when you refactor the pages according to the 640 design? - This stems from a viewport and px understanding .A lot of mobile pages have been refactored, but it's unclear why you should design the page in 640 size. Give the element a fixed pixel value, but the strange thing
/** * from the DP unit according to the resolution of the phone to be px (pixels) */public static int dip2px (context context, float Dpvalue) { final Floa T scale = context.getresources (). Getdisplaymetrics (). density; return (int) (Dpvalue * scale + 0.5f); } /** * According to the resolution of the phone from px (pixels) to the unit to be DP */public static int Px2dip (context context, float Pxva
In some cases, the artist often give me the PX this time we need to according to the screen resolution to turn PX into a dip or SP below is the calculation formula:Package Com.example.test5;import Android.app.activity;import Android.content.context;import android.os.Bundle; Import Android.util.displaymetrics;import Android.util.log;import Android.view.view;import Android.view.view.onclicklistener;import And
In Android, the unit conversion between dip (dp) and px is dip2px dp to px without context algorithm (and to obtain the screen width and height), and androiddip2px

Article Introduction: but the exception of 12px Chinese characters is that the 12px (1.2em) size of Chinese characters obtained by the above method is not equal to the font size defined directly with 12px, but slightly larger. This problem Jorux has been resolved, only in the body selector in the 62.5% to 63% can be normal display. The reason may be that when IE deals with Chinese characters, the precision of floating-point values is limited. Don't know if it
Quoted here is Jorux's
Quoted here is Jorux's "95% Chinese web site needs to rewrite the CSS" article, the topic is a bit scary, but it is now a number of domestic web page production defects. I have not been clear about the relationship between PX and EM and the characteristics, after seeing the harvest is really great. Usually use PX to define fonts, so can not use browser font amplification function, and most foreign websites
In CSS stylesheets, we often see the length units such as PT, Px,em,ex, in, and so on. What do they mean, what's the difference?

Also talk about the difference between PX
PX, PT, EM, ex, and in are our common length units, especially in the font size of Web pages. But do you know how PX, PT, and EM are exchanged? Here Icech for everyone to find a px, PT, EM and percent size conversion of a table, especially for the conversion of font size is very convenient. I hope you can enjoy it!
