French Introduction
Source: Britannica.com
France has a long line of history. From the French Revolution to both World Wars and crisis within its own government, France have seen it all and have emerged stronger as a country.
The French Revolution was a movement that divided France between the years 1787 and 1799. Like most Revolutions there are the same simliar reasons. However, the French Revolution was the most violent of them all. For a decade, French Citizens destroyed their city in an attempt to overthrow power to regain indepemdence. The French Revolution came to an end when a general named Napoleon overthrew the government to establish independence.
The French Revolution had a profound impact on the hierachy structure that ruled France for so long. The French Revolution stripped powers form the Cathloic Church and put an end to the long reign of the French Monarchy. From The Revolution, ideas like liberty and freedom flourished throughout Europe (not just France) and paved the way to a better life for French Citizens.

How to disable the persistent battery icon that appears in YouTube on Pixel 4
by Ben SchoonSome early Pixel 4 owners have noticed that the battery icon in the status bar shows even when viewing YouTube videos in full-screen. It can be pretty annoying, but luckily there’s an easy solution to the problem.
It’s unclear why, but on the Pixel 4 and Pixel 4 XL the battery icon will show when you’re watching YouTube videos where, on other Android phones, it disappears alongside the rest of the status bar. One might assume this is a bug, but it might be intentional since the icon is “dimmed” to make it less obtrusive.
The issue was first highlighted on Twitter and saw several replies mentioning the same issue on other Pixel 4 devices.
There are a couple of quick troubleshooting fixes that can solve this problem. In my case, the status bar was never fully going away in any apps. For whatever reason, turning off developer options fixed the issue on my device and it has not come back since.
For most people that only have the battery icon, though, Android Police noticed that there’s a correlation between the battery icon and the Pixel 4’s Motion Sense feature. When the “Skip Songs” functionality is turned off, the icon disappears.

dpkg-maintscript-helper(1) dpkg suite dpkg-maintscript-helper(1) NAME dpkg-maintscript-helper - works around known dpkg limitations in main‐ tainer scripts SYNOPSIS dpkg-maintscript-helper command [parameter...] -- maint-script-parame‐ ter... COMMANDS AND PARAMETERS rm_conffile conffile [prior-version [package]] mv_conffile old-conffile new-conffile [prior-version [package]] DESCRIPTION This program is designed to be run within maintainer scripts to achieve some tasks that dpkg can't (yet) handle natively either because of design decisions or due to current limitations. Many of those tasks require coordinated actions from several maintainer scripts (preinst, postinst, prerm, postrm). To avoid mistakes the same call simply needs to be put in all scripts and the program will automati‐ cally adapt its behaviour based on the environment variable DPKG_MAINTSCRIPT_NAME and on the maintainer scripts arguments that you have to forward after a double dash. CONFFILE RELATED TASKS When upgrading a package, dpkg will not automatically remove a conffile (a configuration file for which dpkg should preserve user changes) if it is not present in the newer version. There are two principal reasons for this; the first is that the conffile could've been dropped by accident and the next version could restore it, users wouldn't want their changes thrown away. The second is to allow packages to transition files from a dpkg-maintained conffile to a file maintained by the package's maintainer scripts, usually with a tool like debconf or ucf. This means that if a package is intended to rename or remove a conffile, it must explicitly do so and dpkg-maintscript-helper can be used to implement graceful deletion and moving of conffiles within maintainer scripts. REMOVING A CONFFILE If a conffile is completely removed, it should be removed from disk, unless the user has modified it. If there are local modifications, they should be preserved. If the package upgrades aborts, the newly obsolete conffile should not disappear. All of this is implemented by putting the following shell snippet in the preinst, postinst and postrm maintainer scripts: dpkg-maintscript-helper rm_conffile \ conffile prior-version package -- "$@" conffile is the filename of the conffile to remove. prior-version defines the latest version of the package whose upgrade should trigger the removal. It is important to calculate prior-version correctly so that conffiles are correctly removed even if the user rebuilt the package with a local version. For example, for a conffile removed in version 2.0-1 of a package, prior-version should be set to 2.0-1~. This will cause the conffile to be removed even if the user rebuilt the previous version 1.0-1 as 1.0-1local1. If the conffile has not been shipped for several versions, and you are now modifying the maintainer scripts to clean up the obsolete file, prior-version should be based on the version of the package that you are now preparing, not the first version of the package that lacked the conf‐ file. package is the package name. If empty or omitted, the DPKG_MAINTSCRIPT_PACKAGE environment variable (as set by dpkg) will be used. All the parameters of the maintainer scripts have to be forwarded to the program after "--". Current implementation: in the preinst, it checks if the conffile was modified and renames it either to conffile.dpkg-remove (if not modified) or to conffile.dpkg-backup (if modified). In the postinst, the latter file is renamed to conffile.dpkg-bak and kept for reference as it con‐ tains user modifications but the former will be removed. If the package upgrade aborts, the postrm reinstalls the original conffile. During purge, the postrm will also delete the .dpkg-bak file kept up to now. RENAMING A CONFFILE If a conffile is moved from one location to another, you need to make sure you move across any changes the user has made. This may seem a sim‐ ple change to the preinst script at first, however that will result in the user being prompted by dpkg to approve the conffile edits even though they are not responsible of them. Graceful renaming can be implemented by putting the following shell snip‐ pet in the preinst, postinst and postrm maintainer scripts: dpkg-maintscript-helper mv_conffile \ old-conffile new-conffile prior-version package -- "$@" old-conffile and new-conffile are the old and new name of the conffile to rename. prior-version defines the latest version of the package whose upgrade should trigger the rename of the conffile (see the notes for rm_conffile above concerning the correct value). If prior-version is empty or omit‐ ted, then the operation is tried on every upgrade (note: it's safer to give the version and have the operation tried only once). package is the package name. If empty or omitted, the DPKG_MAINTSCRIPT_PACKAGE environment variable (as set by dpkg) will be used. All the parameters of the maintainer scripts have to be forwarded to the program after "--". Current implementation: the preinst checks if the conffile has been modi‐ fied, if yes it's left on place otherwise it's renamed to old-conf‐ file.dpkg-remove. On configuration, the postinst removes old-conf‐ file.dpkg-remove and renames old-conffile to new-conffile if old-conffile is still available. On abort-upgrade/abort-install, the postrm renames old-conffile.dpkg-remove back to old-conffile if required. INTEGRATION IN PACKAGES Given that dpkg-maintscript-helper is used in the preinst, using it unconditionally requires a pre-dependency to ensure that the required version of dpkg has been unpacked before. The required version depends on the command used, for rm_conffile and mv_conffile it is <IP_ADDRESS>: Pre-Depends: dpkg (>= <IP_ADDRESS>) But in many cases the operation done by the program is not critical for the package, and instead of using a pre-dependency we can call the pro‐ gram only if we know that the required command is supported by the cur‐ rently installed dpkg: if dpkg-maintscript-helper supports command; then dpkg-maintscript-helper command ... fi Debian Project 2012-05-04 dpkg-maintscript-helper(1)

BMW orders more than US$11 billion worth of battery cells
BERLIN: German carmaker BMW on Thursday (Nov 21) said it had ordered more than €10 billion (US$11.07 billion) worth of battery cells from Chinese battery cell maker Contemporary Amperex Technology Co (CATL) and Samsung SDI.
BMW said it had boosted its order with CATL to €7.3 billion from an original booking announced in mid-2018 that was worth €4 billion. It said the contract would last from 2020 to 2031.
BMW said it had also signed a battery supply contract with Samsung SDI worth €2.9 billion, valid from 2021 to 2031.
BMW said it would get the cobalt it needs for cell production from mines in Australia and Morocco and provide it to CATL and Samsung SDI. It said it would source the lithium from mines including in Australia.
BMW plans to have 25 electrified models in its offering by 2023, with more than half of them fully electric. It expects sales of electrified vehicles to double between 2019 and 2021.
Europe's auto industry is promoting zero-emissions cars as a way to comply with clean air rules, a strategy shift which forces carmakers to retool their supply chains to build electric, rather than combustion engine cars.

In the "old days," when programmers worked on printing terminals, editing was done one line at a time. Editors that let you move a cursor around the screen to select text to edit hadn't yet been invented, because there weren't any screens to look at text on!
With ever more advanced WYSIWYG (What You See Is What You Get) word processors and editing programs, it's easy for novices to think of line editors as a bizarre relic. Perhaps they are but if so, they are a relic of extraordinary power.
You see, line editors lend themselves to scripting the ability to write what in effect are editing programs that can be applied over and over to different files.
When we talk about "batch editing" or scripts, here are some of the programs you might use:
ed is the original Unix line editor.
ex supports a superset of ed commands; it is widely used from within vi, which is the ex "visual" or "screen" mode.
sed (Section 34.1) is an editor that can only be run with scripts or by entering a few short commands as command-line arguments; while it has many similar commands, it has some important differences (Section 34.2) from ed and ex.
awk (Section 20.10) is a great way to pull apart a line of text into a sequence of elements. Used frequently with sed.
patch (Section 20.9) is a specialized editor designed to apply editing scripts created with diff (Section 11.1). You can do this with ed or ex as well, but patch is especially clever at it.
Of course, editing is a continuum, and beyond sed and awk (Section 20.10) lie more complete programming languages like perl (Section 41.1) and python (Section 42.1) that are very adept at manipulating text.
TOR
When you write a script that contains a series of editing actions and then run the script on an input file, you take what would be a hands-on procedure in an editor such as vi and transform it into a look-no-hands procedure.
When performing edits manually, you get to trust the cause-and-effect relationship of entering an editing command and seeing the immediate result. There is usually an "undo" command that allows you to reverse the effect of a command and return the text file to its previous state. Once you learn an interactive text editor, you have the feeling of making changes in a safe and controlled manner, one step at a time.
Most people new to "power editing" will feel there is greater risk in writing a script to perform a series of edits than in making those changes manually. The fear is that by automating the task, something will happen that cannot be reversed. The object of learning scripting with ex or sed is to understand the commands well enough to see that your results are predictable. In other words, you come to understand the cause-and-effect relationship between your editing script and the output you get.
This requires using the editor in a controlled, methodical way. Gradually, you will develop methods for creating and testing editing scripts. You will come to rely upon these methods and gain confidence that you know what your script is doing and why.
Here are a few tips:
Carefully examine your input file, using grep, before designing your script.
Start with a small sample of occurrences in a test file. Run your script on the sample and make sure the script is working. Remember, it's just as important to make sure the script doesn't work where you don't want it to. Then increase the size of the sample. Try to increase the complexity of the input.
Work carefully, testing each command that you add to a script. Compare the output against the input file to see what has changed. Prove to yourself that your script is complete. Your script may work perfectly based on your assumptions of what is in the input file, but your assumptions may be wrong.
Be pragmatic! Try to accomplish what you can with your script, but understand that it doesn't have to do 100 percent of the job. If you encounter difficult situations, check to see how frequently they occur. Sometimes it's better to do a few remaining edits manually.
If you can add to these tips with your experience, tack them on.
One additional suggestion is to use a revision control system (Section 39.4) to preserve previous versions. That makes it easy to undo your edits.
DD
The key to making line editors work for you is understanding how to select (or "address") the lines that will be affected by the commands in your script.
In ed and ex, a command affects only the "current" line the first line of the file to begin with, and later the site of the last edit or movement command unless you precede the command with an address to indicate some other line or lines. In sed, most commands apply to every line unless you give an address.
Most line editors address lines in three ways:
with line numbers
with regular expression patterns
with special symbols
It's possible to address single lines or a range of lines.
Table 20-1 describes the addresses you can use with ex.
|
Address |
Description |
|---|---|
|
1,$ |
All lines in the file. |
|
% |
All lines; same as 1,$. |
|
x,y |
Lines x through y. |
|
x;y |
Lines x through y, with current line reset to x. |
|
1 |
Top of file. |
|
0 |
"Before the top" of file. Used to add text above top line: 0r, xm0, etc. |
|
. |
Current line. |
|
n |
Absolute line number n. |
|
$ |
Last line. |
|
x-n |
n lines before x. |
|
x+n |
n lines after x. |
|
-n |
n lines previous. |
|
- |
Previous line. |
|
+n |
n lines ahead. |
If the address specifies a range of lines, the format is:
x,y
where x and y are the first and last addressed lines. x must precede y in the file.
TOR, DG, and JP
Many line editor commands are not particularly useful in scripts. The two commands that you will use far and away the most often are s (substitute), to replace one pattern with another, and d (delete), to delete one or more lines. On occasion, though, you'll want to insert text from a script. (Editing scripts built by diff (Section 18.6) make heavy use of insert, append, delete, and change commands.) And of course, you need commands to write the file and quit the editor.
Here's the syntax of most of the commands you may encounter in ex editing scripts. (The ed editor understands the abbreviated versions of some, but not all, of these commands.) Elements in [brackets] are optional; don't type the [ or ]. The leading colon (:) shown in examples is the ex command character used to issue an ex command from vi; in a script, the colon would be omitted. The autoindent feature referred to below aids anyone writing structured text. Your editor can ease the burden of creating outlines and source code by positioning the cursor beneath the first character of the previous line.
[address] a[!] text .
Append text at specified address, or at present address if none is specified. Add a ! to switch the autoindent setting that will be used during input. For example, if autoindent was enabled, ! disables it.
[address] c[!] text .
Replace the specified lines with text. Add a ! to switch the autoindent setting during input of text.
[address] co destination [address] t destination
Copy[1] the lines included in address to the specified destination address.
:1,10 co 50 :1,10t50
[address] d [buffer]
Delete the lines included in address. If buffer is specified, save or append the text to the named buffer.
:/Part I/,/Part II/-1d Delete to line above "Part II" :/main/+d Delete line below "main" :.,$d Delete from this line to last line
[address] g[!]/pattern/[commands]
Execute commands on all lines that contain pattern, or if address is specified, on all lines within that range. If commands are not specified, print all such lines. (Exception: doesn't print when you use it from vi by typing : first. You'll need to add a p, as in the second example below). If ! is used, execute commands on all lines that don't contain pattern.
:g/Unix/ :g/Unix/p :g/Name:/s/tom/Tom/
[address] i[!] text .
Insert text at line before the specified address, or at present address if none is specified. Add a ! to switch the autoindent setting during input of text.
[address] m destination
Move the lines specified by address to the destination address.
:.,/Note/m /END/ Move block after line containing "END"
[address] p [count]
Print the lines specified by address. count specifies the number of lines to print, starting with address.
:100;+5p Show line 100 and the next five lines
q[!]
Terminate current editing session. Use ! to discard changes made since the last save. If the editing session includes additional files in the argument list that were never accessed, quit by typing q! or by typing q twice.
[address] r file
Copy in the text from file on the line below the specified address. If file is not specified, the current filename is used.
:0r $HOME/data Read file in at top of current file
[address] r !command
Read the output of Unix command into the text after the line specified by address.
:$r !cal Place a calendar at end of file
so file
Read and execute ex commands from file.
:so $HOME/.exrc
[address] s [/pattern/replacement/] [options] [count]
Replace first instance of pattern on each of the specified lines with replacement. If pattern and replacement are omitted, repeat last substitution. count specifies the number of lines on which to substitute, starting with address. The following can be used as options:
Prompt for confirmation before each change.
Substitute all instances of pattern on each line.
Print the last line on which a substitution was made.
c Section 17.9, \U Section 17.14
:1,10s/yes/no/g Substitute on first 10 lines :%s/[Hh]ello/Hi/gc Confirm global substitutions :s/Fortran/\U&/ 3 Uppercase "Fortran" on next 3 lines
[address] w[!] [>>] file]
Write lines specified by address to file, or write full contents of buffer if address is not specified. If file is also omitted, save the contents of the buffer to the current filename. If >> file is used, write contents to the end of an existing file. The ! flag forces the editor to write over any current contents of file.
:1,10w name_list Copy first 10 lines to name_list :50w >> name_list Now append line 50
[address] w !command
Write lines specified by address, or write full contents of buffer if address is not specified, to the standard input (Section 43.1) of command.
:1,10w !spell Send first 10 lines to the spell command :w !lpr Print entire buffer with lpr command
TOR and DG
Because vi is built on top of the ex line editor, you get all the power of a line editor as well. Any experienced vi user issues ex commands all the time but usually one by one, at the colon (:) prompt.
The one exception is the .exrc file (Section 17.5), which is, at bottom, a list of commands for ex to run on startup in short, an editor script.
What many beginners don't know is that you can save a sequence of ex commands in any file and execute it with the :so command (Section 20.4). For example, Bruce Barnett uses this trick to set himself up specially for editing FORTRAN programs (Section 18.10).
In general, sed (Section 34.1) is better for general-purpose batch editing such as making a set of global substitutions over and over again on multiple files therefore, :so is most often used for reading in setup commands. Keep in mind, though, any time you find yourself issuing the same commands over and over again, think script!
 They'll apply your same edits to other copies of the same file. This is handy if you have a lot of copies of a big file, spread around a network or on a lot of disks, and you want to make the same changes to all the
files. In fact, this is how the Concurrent Version Control (CVS) system works. Instead of sending new copies of the whole file, just have diff make a script and use that little script to update all the big files.
Here's a demo. I'm going to modify a program called pqs.c. Then I'll use diff and ed to apply the same changes to a copy of the file named remote-pqs.c (which might be at a remote computer):

At prompt 1%, I make the simulated "remote" copy of the pqs.c file. At prompt 2%, I make another copy of it; at prompt 3%, I edit the copy. Prompt 4% has a diff that shows the changes I made. Then, at prompt 5%, I run diff -e (Section 11.1); I save the result in edscr, which I show at prompt 6%.
Prompt 7% is important because diff -e doesn't add a w command to the script file. That tells ed to write its changes to the file. I use echo w (Section 27.5) to add the command.
In prompt 8%, I give ed the name of the "remote" file to edit as a command-line argument and give it the script file on its standard input. At prompt 9%, I do a diff that shows the changes have been made and the two versions are the same.
If you find yourself needing to keep multiple copies of the same set of files in sync with each other, you might want to consider using CVS. Not only is it a client/server system ready for network use, it is also designed for multiple users. Every check-in is logged, and updating a whole set of files (called "projects") can be done with the command cvs update. This can be a great timesaver for webmasters maintaining multiple web servers with static (or even dynamic) content.
Another great tool for synchronizing many filesystems is rsync. This program can be used to update a remote filesystem, say a web directory, with more current version of existing files or add new ones. The synchronization can go both ways. rsync even has built-in support for SSH. Here's an example of using rsync to publish new web documents to a live server:
$ rsync -urz -e /path/to/ssh local_dir hostname:/path/to/web/docs
The -u flag tells rsync to update the remote filesystem with newer files on the local system. The -r flag tells rsync to recurse into subdirectories. The -z allows the files to be gzipped during transfer (good for slow modem links). While it can be a client/server system, rsync can work just fine as a peer-to-peer system where it will need to run some commands on the remote machine. The -e flag provides the path to the rsh or ssh program that you to have rsync use. The next argument is the directory on the local machine rsync is to copy, and the last argument is the hostname and target directory to be updated. rsync is a very handy tool, and the manpage illustrates its flexibility.

What ed and ex lack in intutitive interface design, they make up for when used in batch editing shell scripts. For example, you might be maintaining a web site with a lot of static content all stored in traditional HTML files. One such file might look like this:

Hello, world!

Glad you could make it .
Here's a picture of my house:
One day, you get an email that all the images will now be served out of the directory /img instead of /graphics. Also, all existing gif files have been replaced with png files. Although these changes don't sound like much, making these modifications to a large number of files quickly becomes tedious. By writing a shell script that calls either ed or ex, you will not only solve today's problem, but you'll also be ready to make new changes to the files whenever that becomes necessary. A Bourne shell script that makes these changes looks like the following:
#!/bin/sh # Convert some of the hard coded values in HTML # into the new site schema # Patterns to be replaced old_graphics_dir="graphics" old_graphics_ext="gif" # new values new_graphics_dir="img" new_graphics_ext="png" # Make the changes for file in *html; do ed $file <<EOF 1,\$s/$old_graphics_dir/$new_graphics_dir/g 1,\$s/$old_graphics_ext/$new_graphics_ext/g w EOF done
The script is fairly simple. It defines a few variables to hold the patterns to be found and replaced. The replacement values are defined next. This script is meant to be run in the directory containing all the HTML files. The list of all files ending in "html" is iterated over in a for loop in which ed is fed commands from a here document. Recall that $ is a special character for Bourne shell and must be escaped in the line-addressing part of the ed command. After the search and replace operations finish, the ed buffers need to be written back to disk with the w command. This script works with both ed and ex.
In older versions of ed, you may find that if the first pattern doesn't match, ed doesn't even try the second pattern. If your version does this, one workaround suggested by Chris Torek is to use the global command g like this:
ed - $i << end g/$old_graphics_dir/s//$new_graphics_dir/g g/$old_graphics_ext/s//$new_graphics_ext/g w end
The addition of the - suppresses the two numbers that ed normally prints.

People use the ed editor with script files to make global edits. But many versions of ed can't edit large files. The ex editor is usually better, but it has limits, too. How large is "large"? That depends on your version. Most eds I've seen can't handle more than about 100,000 characters.
There are no limits on sed (Section 34.1), although you'll need to save its output somehow (Section 34.4), and your editing script may have to be changed to work with sed.[2] Here's what you'll see when ed fails:
% cat edscr s/Unix/UNIX/g w % ed - words < edscr ? %
The ? is ed's "verbose" way of telling you that something's wrong. This obscure message is especially bad if you write a shell script that edits multiple files in a loop; you may not notice the error or be able to tell which file had the problem. Be sure your script checks for errors!
Unfortunately for programmers, ed may not return an error status that you can test. There are workarounds, though. When the ed - command succeeds, it doesn't display anything. The simplest way to find errors is to check for any output on stdout or stderr. This chunk of a Bourne shell script shows how (your filename is in the shell variable $filename (Section 35.9)):
2>&1 Section 36.16, [ ] Section 35.26, $? Section 35.12
edout="`ed - $filename < edscr 2>&1`" if [ -n "$edout" -o $? -ne 0 ] then echo "$edout" 1>&2 echo "QUITTING: 'ed - $filename < edscr' failed?!?" 1>&2 exit 1 fi

Go to http://examples.oreilly.com/upt3 for more information on: patch
Like all of Larry Wall's widely used programs (including perl (Section 41.1), a software configuration script called Configure, and the rn news reader), patch betrays a whimsical intelligence of its own. Feed it any kind of diff listing (Section 11.1) (not just an editing script produced with the -e option the typical way before patch came around). patch figures out what it needs to do to apply the diff, and updates the file, supplying all the while a breezy commentary on what it's doing:
% patch < testfile.diff Hmm... Looks like a normal diff to me... File to patch: testfile Patching file testfile using Plan A... Hunk #1 succeeded at 2. done
As Larry once noted, patch has done an awful lot to "change the culture of computing." Almost all free software is now updated by means of patches rather than complete new releases. patch is smart enough to discard any leading or trailing garbage (such as mail headers or signatures), so a program source file can be updated by piping a mail message containing a diff listing between old and new versions directly to patch.
Here are a few of the other things patch is smart enough to do:
Figure out the name of the file to be updated and do it without asking (usually only if the diff file is a context diff (Section 11.3) produced with the -c option).
Look for a suitable RCS or CVS (Section 39.4) file and check it out, if the filename itself can't be found.
Handle diff listings that don't quite match. This makes it possible for patch to update a file that the recipient has already changed from the one that the diff was based on.
Save any pieces of the diff file that don't end up being used, in a file named by adding the suffix .rej (reject) to the name of the file being patched.
Back up the file that is being patched, appending the suffix .orig to the name of the file being patched.
Recognize that its input may actually apply to several files, and patch each of them separately. For example, a whole directory might be updated by a "patch" file that contained diff listings for each of the files in the directory. (By the way, the -d option to patch tells it to cd to a specified directory before starting work.)
Recognize (or at least speculate) that a patch might have been created incorrectly, with the old and new files swapped. Larry says, "Yes, I'm afraid that does happen occasionally, human nature being what it is." patch's -R option will force patch to reverse the sense of the patch; what's really amusing is to see patch suggest that this might be the thing to do, when things seem out of sync.
If you are a programmer, patch is worth studying just to see how much a program can do to anticipate errors, deal with fuzzy input, and in general "make the computer do the dirty work."
One last note: patch is so useful that it's been added to many Unix systems. Check to see if your system has it before installing the program. Some versions of patch we've seen are limted versions or buggy when they come from software vendors, though. The one on the book's website is worth comparing to yours.

Up to this point, we've shown you tools to do basic batch editing of text files. These tools, although powerful, have limitations. Although you can script ex commands, the range of text manipulation is quite limited. If you need more powerful and flexible batch editing tools, you need to look at programming languages that are designed for text manipulation. One of the earliest Unix languages to do this is awk, created by Al Aho, Peter Weinberger, and Brian Kernighan. Even if you've never programmed before, there are some simple but powerful ways that you can use awk. Whenever you have a text file that's arranged in columns from which you need to extract data, awk should come to mind.
For example, every Red Hat Linux system stores its version number in /etc/redhat-release. On my system, it looks like this:
Red Hat Linux release 7.1 (Seawolf)
When applying new RPM files to your system, it is often helpful to know which Red Hat version you're using. On the command line, you can retrieve just that number with:
awk '{print $5}' /etc/redhat-release
What's going on here? By default, awk splits each line read from standard input on whitespace, as is explained below. In effect, it's like you are looking at one row of a spreadsheet. In spreadsheets, columns are usually named with letters. In awk, columns are numbered and you only can see one row (that is, one line of input) at a time. The Red Hat version number is in the fifth column. Similar to the way shells use $ for variable interpolation, the values of columns in awk are retrieved using variables that start with $ and are followed by an integer.
As you can guess, this is a fairly simple demostration of awk, which includes support for regular expressions, branching and looping, and subroutines. For a more complete reference on using awk, see Effective awk Programming or sed & awk Pocket Reference, both published by O'Reilly.
Since there are many flavor of awk, such as nawk and gawk (Section 18.11), this article tries to provide a usable reference for the most common elements of the language. Dialect differences, when they occur, are noted. With the exception of array subscripts, values in [brackets] are optional; don't type the [ or ].
awk can be invoked in one of two ways:
awk [options] 'script' [var=value] [file(s)] awk [options] -f scriptfile [var=value] [file(s)]
You can specify a script directly on the command line, or you can store a script in a scriptfile and specify it with -f. In most versions, the -f option can be used multiple times. The variable var can be assigned a value on the command line. The value can be a literal, a shell variable ($name), or a command substitution ('cmd'), but the value is available only after a line of input is read (i.e., after the BEGIN statement). awk operates on one or more file(s). If none are specified (or if - is specified), awk reads from the standard input (Section 43.1).
The other recognized options are:
Set the field separator to character c. This is the same as setting the system variable FS. nawk allows c to be a regular expression (Section 32.4). Each record (by default, one input line) is divided into fields by whitespace (blanks or tabs) or by some other user-definable field separator. Fields are referred to by the variables $1, $2, . . . $n. $0 refers to the entire record. For example, to print the first three (colon-separated) fields on separate lines:
% awk -F: '{print $1; print $2; print $3}' /etc/passwd
Assign a value to variable var. This allows assignment before the script begins execution. (Available in nawk only.)
awk scripts consist of patterns and procedures:
pattern {procedure}
Both are optional. If pattern is missing, {procedure} is applied to all records. If {procedure} is missing, the matched record is written to the standard output.
pattern can be any of the following:
/regular expression/ relational expression pattern-matching expression BEGIN END
Expressions can be composed of quoted strings, numbers, operators, functions, defined variables, and any of the predefined variables described later in Section 20.10.3.
Regular expressions use the extended set of metacharacters, as described in Section 32.15. In addition, ^ and $ (Section 32.5) can be used to refer to the beginning and end of a field, respectively, rather than the beginning and end of a record (line).
Relational expressions use the relational operators listed in Section 20.10.4 later in this article. Comparisons can be either string or numeric. For example, $2 > $1 selects records for which the second field is greater than the first.
Pattern-matching expressions use the operators ~ (match) and !~ (don't match). See Section 20.10.4 later in this article.
The BEGIN pattern lets you specify procedures that will take place before the first input record is processed. (Generally, you set global variables here.)
The END pattern lets you specify procedures that will take place after the last input record is read.
Except for BEGIN and END, patterns can be combined with the Boolean operators || ( OR), && (AND), and ! (NOT). A range of lines can also be specified using comma-separated patterns:
pattern,pattern
procedure can consist of one or more commands, functions, or variable assignments, separated by newlines or semicolons (;), and contained within curly braces ({}). Commands fall into four groups:
Variable or array assignments
Printing commands
Built-in functions
Control-flow commands
Print the first field of each line:
{ print $1 }
Print all lines that contain pattern:
/pattern/
Print first field of lines that contain pattern:
/pattern/{ print $1 }
Print records containing more than two fields:
NF > 2
Interpret input records as a group of lines up to a blank line:
BEGIN { FS = "\n"; RS = "" } { ...process records... }
Print fields 2 and 3 in switched order, but only on lines whose first field matches the string URGENT:
$1 ~ /URGENT/ { print $3, $2 }
Count and print the number of pattern found:
/pattern/ { ++x } END { print x }
Add numbers in second column and print total:
{total += $2 }; END { print "column total is", total}
Print lines that contain fewer than 20 characters:
length($0) < 20
Print each line that begins with Name: and that contains exactly seven fields:
NF == 7 && /^Name:/
nawk supports all awk variables. gawk supports both nawk and awk.

Expressions using the operators +, -, *, /, and % (modulus) can be assigned to variables.
Arrays can be created with the split function (see below), or they can simply be named in an assignment statement. Array elements can be subscripted with numbers (array[1], . . . ,array[n]) or with names (as associative arrays). For example, to count the number of occurrences of a pattern, you could use the following script:
/pattern/ { array["pattern"]++ } END { print array["pattern"] }

The following alphabetical list of statements and functions includes all that are available in awk, nawk, or gawk. Unless otherwise mentioned, the statement or function is found in all versions. New statements and functions introduced with nawk are also found in gawk.
atan2(y,x)
Returns the arctangent of y/x in radians. (nawk)
Exit from a while, for, or do loop.
close(filename-expr) close(command-expr)
In some implementations of awk, you can have only ten files open simultaneously and one pipe; modern versions allow more than one pipe open. Therefore, nawk provides a close statement that allows you to close a file or a pipe. close takes as an argument the same expression that opened the pipe or file. (nawk)
Begin next iteration of while, for, or do loop immediately.
cos(x)
Return cosine of x (in radians). (nawk)
delete array[element]
Delete element of array. (nawk)
do body while (expr)
Looping statement. Execute statements in body, then evaluate expr. If expr is true, execute body again. More than one command must be put inside braces ({}). (nawk)
exit[expr]
Do not execute remaining instructions and do not read new input. END procedure, if any, will be executed. The expr, if any, becomes awk's exit status (Section 34.12).
exp(arg)
Return the natural exponent of arg.
for ([init-expr]; [test-expr]; [incr-expr]) command
C-language-style looping construct. Typically, init-expr assigns the initial value of a counter variable. test-expr is a relational expression that is evaluated each time before executing the command. When test-expr is false, the loop is exited. incr-expr is used to increment the counter variable after each pass. A series of commands must be put within braces ({}). For example:
for (i = 1; i <= 10; i++) printf "Element %d is %s.\n", i, array[i]
for (item in array) command
For each item in an associative array, do command. More than one command must be put inside braces ({}). Refer to each element of the array as array[item].
getline [var][<file] or command | getline [var]
Read next line of input. Original awk does not support the syntax to open multiple input streams. The first form reads input from file, and the second form reads the standard output of a Unix command. Both forms read one line at a time, and each time the statement is executed, it gets the next line of input. The line of input is assigned to $0, and it is parsed into fields, setting NF, NR, and FNR. If var is specified, the result is assigned to var and the $0 is not changed. Thus, if the result is assigned to a variable, the current line does not change. getline is actually a function, and it returns 1 if it reads a record successfully, 0 if end-of-file is encountered, and -1 if for some reason it is otherwise unsuccessful. (nawk)
gsub(r,s[,t])
Globally substitute s for each match of the regular expression r in the string t. Return the number of substitutions. If t is not supplied, defaults to $0. (nawk)
if (condition) command [else command]
If condition is true, do command(s), otherwise do command(s) in else clause (if any). condition can be an expression that uses any of the relational operators <, <=, ==, != , >=, or >, as well as the pattern-matching operators ~ or !~ (e.g., if ($1 ~ /[Aa].*[Zz]/)). A series of commands must be put within braces ({}).
index(str,substr)
Return position of first substring substr in string str or 0 if not found.
int(arg)
Return integer value of arg.
length(arg)
Return the length of arg.
log(arg)
Return the natural logarithm of arg.
match(s,r)
Function that matches the pattern, specified by the regular expression r, in the string s and returns either the position in s where the match begins or 0 if no occurrences are found. Sets the values of RSTART and RLENGTH. (nawk)
Read next input line and start new cycle through pattern/procedures statements.
print [args] [destination]
Print args on output, followed by a newline. args is usually one or more fields, but it may also be one or more of the predefined variables or arbitrary expressions. If no args are given, prints $0 (the current input record). Literal strings must be quoted. Fields are printed in the order they are listed. If separated by commas (,) in the argument list, they are separated in the output by the OFS character. If separated by spaces, they are concatenated in the output. destination is a Unix redirection or pipe expression (e.g., > file) that redirects the default standard output.
printf format [, expression(s)] [destination]
Formatted print statement. Fields or variables can be formatted according to instructions in the format argument. The number of expressions must correspond to the number specified in the format sections. format follows the conventions of the C-language printf statement. Here are a few of the most common formats:
A string.
A decimal number.
A floating-point number, where n is the total number of digits and m is the number of digits after the decimal point.
n specifies minimum field length for format type c, while - left-justifies value in field; otherwise value is right-justified.
format can also contain embedded escape sequences: \n (newline) or \t (tab) are the most common. destination is a Unix redirection or pipe expression (e.g., > file) that redirects the default standard output.
For example, using the following script:
{printf "The sum on line %s is %d.\n", NR, $1+$2}
and the following input line:
5 5
produces this output, followed by a newline:
The sum on line 1 is 10.
rand( )
Generate a random number between 0 and 1. This function returns the same series of numbers each time the script is executed, unless the random number generator is seeded using the srand( ) function. (nawk)
return [expr]
Used at end of user-defined functions to exit the function, returning value of expression expr, if any. (nawk)
sin(x)
Return sine of x (in radians). (nawk)
split(string,array[,sep])
Split string into elements of array array[1], . . . ,array[n]. string is split at each occurrence of separator sep. (In nawk, the separator may be a regular expression.) If sep is not specified, FS is used. The number of array elements created is returned.
sprintf (format [, expression(s)])
Return the value of expression(s), using the specified format (see printf). Data is formatted but not printed.
sqrt(arg)
Return square root of arg.
srand(expr)
Use expr to set a new seed for random number generator. Default is time of day. Returns the old seed. (nawk)
sub(r,s[,t])
Substitute s for first match of the regular expression r in the string t. Return 1 if successful; 0 otherwise. If t is not supplied, defaults to $0. (nawk)
substr(string,m[,n])
Return substring of string, beginning at character position m and consisting of the next n characters. If n is omitted, include all characters to the end of string.
system(command)
Function that executes the specified Unix command and returns its status (Section 34.12). The status of the command that is executed typically indicates its success (0) or failure (nonzero). The output of the command is not available for processing within the nawk script. Use command | getline to read the output of the command into the script. (nawk)
tolower(str)
Translate all uppercase characters in str to lowercase and return the new string. (nawk)
toupper(str)
Translate all lowercase characters in str to uppercase and return the new string. (nawk)
while (condition) command
Do command while condition is true (see if for a description of allowable conditions). A series of commands must be put within braces ({}).

awk was introduced as part of Unix's seventh edition and has been part of the standard distribution ever since.
In 1985, the authors of awk extended the language, adding many useful features. Unfortunately, this new version remained inside AT&T for several years. It became a regular part of AT&T's System V as of Release 3.1. It can be found under the name of nawk (for "new awk"); the older version still exists under its original name.
Go to http://examples.oreilly.com/upt3 for more information on: gawk
Unfortunately, nawk is not available on all systems. The good news is that the Free Software Foundation GNU project's version of awk, called gawk, implements all the features of the new awk.
In general, you can assume that what is true for nawk is true for gawk, unless gawk is explicitly called out. Scripts written for nawk are 100 percent compatible with gawk. If you want to use one of the nawk scripts and don't have nawk on your system, simply change the script to invoke gawk instead.
There are a few areas where gawk has introduced gawk-specific features; however, recent versions of nawk support many of these features, suggesting that the remaining differences are really very minor. This shouldn't matter in any case, since we do supply gawk on the disc.
This book doesn't cover any of the awks in detail. The recent awks, especially, have quite a few features in common so documentation for any one of them should help you learn the others.
In this book, we show scripts for awk as well as scripts that work only on nawk and gawk. But we barely scratch the surface of all the awks' features. The completely revised second edition of O'Reilly & Associates' sed & awk has detailed information on all of them.[4] There's also lots of documentation on the CD-ROM [see http://examples.oreilly.com/upt3]. Take your pick.

[1] Note that "t" is short for "to." The ed editor only has one-letter commands and since "c" was already taken for "change," they used "t" for "copy TO."
[2] By default, ed commands apply to the current line. sed commands are global. Also, relative line addresses like -5 don't work in sed.

React
This is a part of the series “Henry is getting ready for Olavstoppen”. You can find the other posts by following the tag “Getting Ready 4 OT”.
To learn React I have been following this React course by Wes Bos. And the following is mostly my notes and ramblings trying to digest it.
React is, according to reactjs.org, “A JavaScript library for building user interfaces.”
- Creating our first Component
- Writing HTML with JSX
- Linking up your CSS-file
- Passing dynamic data with Props
- Routing with React Router
- Helper functions
- Events, Refs and this Binding
- Rule number 1: Don’t touch the DOM.
- State
- Looping over something (and showing it in the view)
- ES6 destructuring assignment
Creating our first Component
Everything is a component.
// src/index.js
import React from 'react';
class SomeComponent extends React.Component{
render(){
return
Hello!

}
}
Every component needs a render()
method.
If we want this to actually render, we need to add some more code
// src/index.js
import React from 'react';
import { render } from 'react-dom'; //Since we are building a web-app
class SomeComponent extends React.Component{
render(){
return
Hello!

}
}
render(<SomeComponent />, document.querySelector('#main'));
Its good practice to put all components in separate files. So…
Let’s move our component into a folder called components. And name it as SomeComponent.js
.
// src/components/SomeComponent.js
import React from 'react';
class SomeComponent extends React.Component{
render(){
return
Hello!

}
export default SomeComponent;
}
Note: We need to import React in this file as well. Worry not; This won’t make your application larger when built. We also need to export our component so that other components can use it.
And we need to import it in our index.js
file.
// src/index.js
import React from 'react';
import { render } from 'react-dom';
import SomeComponent from './components/SomeComponent'; // <- Remember to import it
render(<SomeComponent />,document.querySelector('#main'));
Writing HTML with JSX
When returning HTML, you can only return one element. So you have to wrap siblings into a <React.Fragment>
or a

.
Comments need to look like this: {/* Comment */}
.
And the comment cannot be first (as a sibling) in a return statement… Because then you would return just the comment. Even the comments need to be wrapped.
// src/components/SomeComponent.js
import React from 'react';
class SomeComponent extends React.Component{
render(){
return (
<React.Fragment>
{/* Comment */}

Hello!

</React.Fragment>
);
}
export default SomeComponent;
}
Disclaimer: I hope this code works. Haven’t checked it since this is mostly for my own learning.
Linking up your CSS-file
To link your CSS file you just need to import it.
// src/index.js
import React from 'react';
import { render } from 'react-dom';
import SomeComponent from './components/SomeComponent';
import "./css/style.css"; // <- It's as simple as that!
render(<SomeComponent />,document.querySelector('#main'));
Passing dynamic data with Props
Props is the way we get data into a component.
How do we access the data when passing it as a prop?
There are no preset props, so you can just make up your own. Like myRandomProp
.
// src/index.js
import React from 'react';
import { render } from 'react-dom';
import SomeComponent from './components/SomeComponent';
import "./css/style.css";
render(
<SomeComponent myRandomProp="HELLO WORLD!"/>,
document.querySelector('#main')
);
Props are kind of an object of data that is sent into a component.
You can also send other types of props, like bools:
myBoolProp = {true}
or ints:myIntProp = {100}
.
Routing with React Router
The routing is not baked into react (like in angular), we have to use an external component. The two most popular ones are React Router and Next.js.
Let’s use React Router for now.
So we make another component and call it Router.js
in our components directory.
// src/components/Router.js
import React from "react";
import {BrowserRouter, Route, Switch } from 'react-router-dom';
const Router = () => (
<BrowserRouter>
<Switch>
<Route exact path = "/" component={SomeComponent} />
<Route exact path = "/store/:storeID" component={SomeOtherComponent} />
<Route component={NotFoundComponent} />
</Switch>
</BrowserRouter>
)
export default Router;
// src/index.js
import React from 'react';
import { render } from 'react-dom';
import Router from "./components/Router"; // <- Import the router
// import SomeComponent from './components/SomeComponent'; <- Remove this
import "./css/style.css";
render(
<Router />,
document.querySelector('#main')
);
Helper functions
Not something special for React, but it’s smart to put your “helper-functions” somewhere logical like a helpers.js
file.
// helpers.js
export default myHelperFunction(){
return(true);
}
Events, Refs and this Binding
Events
You can add events to elements by adding it inline onClick={this.handleClick}
import React from 'react';
class MyComponent extends React.Component{
handleClick(){
alert("Hello World!");
}
render(){
return <button onClick={this.handleClick}>Click Me!</button>
}
}
Note: We don’t want to write our onClick with “()“s cause that would make the handleClick trigger when mounting the module.
// The wrong way:
<button onClick={this.handleClick()}>Click Me!</button> //<- Wrong!
// This would make the handleClick trigger on mounting the module.
// The correct way:
<button onClick={this.handleClick}>Click Me!</button> //<- Correct!
// Our button will only trigger the handleClick when pressed.
Ref and Binding
The golden rule in react is: “Don’t touch the DOM!”, so we have to ref stuff by creating a ref in the top of your class and adding a ref-attribute to your element.
//NB this will not work
import React from 'react';
class MyComponent extends React.Component{
myInput = React.createRef();
handleClick(){
alert("Hello World!");
console.log(this.myInput); //<- UNDEFINED!
}
render(){
return <input ref={this.myInput} />
}
}
But trying to reach this.myInput
from another method in the same class would not work and just yield undefined.
So to circumvent this, we can rebind the this
to point to the same class in the whole class.
We do this in a Constructor function
import React from 'react';
class MyComponent extends React.Component{
myInput = React.createRef();
constructor(){
super(); // <- We need this
this.MyComponent = this.MyComponent.bind(this) // This binds the this-scope
}
handleClick(){
alert("Hello World!");
console.log(this.myInput);
}
render(){
return <input ref={this.myInput} />
}
}
Now we should be able to ref the input, but if we want to ref a lot of stuff, our class would soon be filled with a lot of this.MyComponent = this.MyComponent.bind(this)
.
The solution to this problem is to use a funky formatting of our methods that makes the method a property of the class.
handleClick = (event) => {
import React from 'react';
class MyComponent extends React.Component{
myInput = React.createRef();
handleClick = (event ) => { //<- THIS IS FUNKY!
alert("Hello World!");
console.log(this.myInput); // <- We can still reach it!
}
render(){
return <input ref={this.myInput} />
}
}
Rule number 1: Don’t touch the DOM.
We don’t want to touch the DOM when writing React apps. We want to change the data, and then see the DOM react to it.
State
State is essentially just an object that lives inside a component that stores data that itself needs and maybe also what other components needs.
Sharing state
We can’t pass data up, only down the stream. Therefore, we need to store stuff that should be shared in a higher component like the Appcomponent.
state = {
fishes:{},
order:{}
}
How do you use a method from Appcomponent in a child-component? The answer is Props!
So let’s say we have a method called addFish
. Then we cas send it to Inventory
-component as a prop like this:
// app.js
// Appcomponent
class App extends React.Component{
state = {
fishes: {},
order:{}
}
addFish = fish => {
console.log("Add some fish")
}
render(){
return(
<Inventory addFish={this.addFish} />
)
}
}
And then in our Inventory
-Component, we can access it through this.props.addFish
.
BUT: In order to update our state we want to:
// Take a copy of the existing state.
// ( We don't want to directly work on the state)
const fishes = {...this.state.fishes}
// Add our new fish to that new fishes variable
fishes[`fish${Date.now()}`]=fish;
// Update our state with the new ``fishes`` object
this.setState({fishes});
Note, we don’t need to pass our whole state to the setState()
-method, only the parts we want to change.
Then setState()
will update our state
-object in the current component.
Looping over something (and showing it in the view)
JSX does not have any logic like other template languages… So we need to do it with JavaScript.
{Object.keys(this.state.fishes).map(key => <Fish key={key}/>}
And relevant data as a prop…
{Object.keys(this.state.fishes).map(key => <Fish key={key} details={this.state.fishes[key]} />}
ES6 destructuring assignment
This:
const name = this.props.details.name;
const image = this.props.details.image;
const name = this.props.details.price;
Can be replaced with:
const {name, image, price}= this.props.details;

EasySettings
Introduction
What is it?
EasySettings is a library whose purpose is to help creating creative project with removing the part of creating ui to change some settings on the go.
Setup
To use this library you have to simply include two files from this repo:
EasySettings.js
found in/build/js/
EasySettings.css
found in/build/css/
Usage
Firstly start with creating panel and assigning it to variable. (See more here: module:Panel)
const panel = new EasySettings();
Then you can create section...
panel.createSection();
...and start Section.adding components (See more here: module:Section)
const section = panel.createSection()
section.Section.addHeader( null, { value: "Dropdown" } );
Thanks to the fact that createSection
as well as all of components return section object you can chain calls.
panel.createSection()
.Section.addHeader( null, { value: "Dropdown" } )
.Section.addDropdown( "dropdown", { options: ["Dropdown option #1", "Dropdown option #2"] });
Components
Basics
Every component is based on the same structure meaning:
Section.Section.addComponentName( id, options, callback );
id
– identifier of component used for getting an setting value of component. If you don't need use it simply set it to null
.
options
– JS object that specifies multiple options specific to the component.
callback
– function that is triggered on every change. Current value of component will be passed as first attribute.
List of all components:
Section.addButton( id, options, callback );
Section.addCheckbox( id, options, callback );
Section.addColorInput( id, options, callback );
Section.addDateInput( id, options, callback );
Section.addDateTimeInput( id, options, callback );
Section.addDropdown( id, options, callback );
Section.addHeader( id, options );
Section.addHTML( id, options );
Section.addNumberInput( id, options, callback );
Section.addParagraph( id, options );
Section.addPasswordInput( id, options, callback );
Section.addProgress( id, options, callback );
Section.addRadio( id, options, callback );
Section.addSlider( id, options, callback );
Section.addTextarea( id, options, callback );
Section.addTextInput( id, options, callback );
Section.addTimeInput( id, options, callback );
For more info about components see module:Section
Getting and setting values
To get value of component you can use module:Panel#getValue
Section.getValue( id );
To set value of component you can use module:Panel#setValue
Section.setValue( id, value );
You can also get values as JSON using module:Panel#getValuesAsJSON
Section.getValuesAsJSON( id );
And set them using JSON with module:Panel#setValuesFromJSON
Section.setValuesFromJSON( id, value );
Where id
is id of component specified at creation of component and value
is value to be set.
Miscellaneous
To toggle determination on progress bar use module:Panel#toggleIndeterminate
const panel = new EasySettings();
panel.Section.addSection()
.Section.addProgress( "progress", { value: 0.33, indeterminate: true } );
panel.toggleIndeterminate( "progress" ); // progress bar now is not indeterminate
If you want to smoothly animate through values you can use module:Panel#animateValue
const panel = new EasySettings();
panel.createSection()
.Section.addSlider( "slider", { value: 25, min: 0, max: 1000 }, ( v ) => {
panel.setValue( "input-number-slider", v );
} )
.Section.addButton( null, null, () => {
panel.animateValue( "slider", 500, 500 );
} );
// after clicking the button slider will animate till it gets to the value of 500
Demo
You can see demo of all components here: https://bibixx.github.io/EasySettings/demo/

2.5. ReferencesA reference serves as an alternative name for an object. In real-world programs, references are primarily used as formal parameters to functions. We'll have more to say about reference parameters in Section 7.2.2 (p. 232). In this section we introduce and illustrate the use of references as independent objects. A reference is a compound type that is defined by preceding a variable name by the & symbol. A compound type is a type that is defined in terms of another type. In the case of references, each reference type "refers to" some other type. We cannot define a reference to a reference type, but can make a reference to any other data type. A reference must be initialized using an object of the same type as the reference: int ival = 1024; int &refVal = ival; // ok: refVal refers to ival int &refVal2; // error: a reference must be initialized int &refVal3 = 10; // error: initializer must be an object A Reference Is an AliasBecause a reference is just another name for the object to which it is bound, all operations on a reference are actually operations on the underlying object to which the reference is bound: refVal += 2; adds 2 to ival, the object referred to by refVal. Similarly, int ii = refVal; assigns to ii the value currently associated with ival.
The important concept to understand is that a reference is just another name for an object. Effectively, we can access ival either through its actual name or through its alias, refVal. Assignment is just another operation, so that when we write refVal = 5; the effect is to change the value of ival to 5. A consequence of this rule is that you must initialize a reference when you define it; initialization is the only way to say to which object a reference refers. Defining Multiple ReferencesWe can define multiple references in a single type definition. Each identifier that is a reference must be preceded by the & symbol: int i = 1024, i2 = 2048; int &r = i, r2 = i2; // r is a reference, r2 is an int int i3 = 1024, &ri = i3; // defines one object, and one reference int &r3 = i3, &r4 = i2; // defines two references const ReferencesA const reference is a reference that may refer to a const object: const int ival = 1024; const int &refVal = ival; // ok: both reference and object are const int &ref2 = ival; // error: non const reference to a const object We can read from but not write to refVal. Thus, any assignment to refVal is illegal. This restriction should make sense: We cannot assign directly to ival and so it should not be possible to use refVal to change ival. For the same reason, the initialization of ref2 by ival is an error: ref2 is a plain, nonconst reference and so could be used to change the value of the object to which ref2 refers. Assigning to ival through ref2 would result in changing the value of a const object. To prevent such changes, it is illegal to bind a plain reference to a const object.
A const reference can be initialized to an object of a different type or to an rvalue (Section 2.3.1, p. 45), such as a literal constant: int i = 42; // legal for const references only const int &r = 42; const int &r2 = r + i; The same initializations are not legal for nonconst references. Rather, they result in compile-time errors. The reason is subtle and warrants an explanation. This behavior is easiest to understand when we look at what happens when we bind a reference to an object of a different type. If we write double dval = 3.14; const int &ri = dval; the compiler transforms this code into something like this: int temp = dval; // create temporary int from the double const int &ri = temp; // bind ri to that temporary If ri were not const, then we could assign a new value to ri. Doing so would not change dval but would instead change temp. To the programmer expecting that assignments to ri would change dval, it would appear that the change did not work. Allowing only const references to be bound to values requiring temporaries avoids the problem entirely because a const reference is read-only.
A const reference may be bound to an object of a different but related type or to an rvalue. |

First, we were curious to see what were people's sentiment about the vaccination process.
Are there a lot of unrest? Are what people saying objective? Are there a lot of negative emotions involved in
the language?
The model was trained on TextBlob to gain sentiments.
The polarity ranges from -1 to 1 - -1 being most negative and 1 being most positive. The subjectivity
ranges from 0 to 1 - 0 being the least subjective and 1 being the most subjective. People were quite
subjective when discussing vaccines. From the distribution, we can see that there are general normal distribution
from both positivity and subjectivity.
We tried to analyze if different communities (subreddits) exhibit different qualities in terms of positivity and
subjectivity. However, the distribution across all subreddits, the distribution seemed to be similar.
This was quite surprising that vaccination is quite a heated subject in this time, yet people
are trying to maintain subjectivity when discussing the matter.
Now that we have seen how people feel about vaccine in the online community. We wanted to
see what are the main concerns of the people. Utilizing gensim's LDA model, we were able to extract some of the
key topics that the communities were discussing online.
It occurred that many feared vaccination may be the cause of autism and cancer.
Also, many of the keywords and topics were related to children. As parents it is natural for them to
worry about the well being, and many seems to be concerned about giving vaccination to their children.
There were also some fundamental distrust in the government, researches, and clinical trials. Those
concerns should be addressed.
Because the global pandemic, many of the Covid-19 vaccine manufacturers' names were discussed. Namely, Pfizer
and AZ, whether taking one of the other is better for the people. Also, a lot about fever and various
covid side-effects were discussed widely.
These topics were used to create the main part of the survey. It was fascinating to
see the variety of topics in the reddit community.


What is this?
Pretty simple. Every 15 minutes, TSHN scrapes the first page of Hacker News and generates a new page containing the top stories from the past 24 hours sorted in descending order by overall points.

I was bored as we were having our winter holidays, so I started reading about
Beautiful Soup. I was simultaneously checking out HN in a different tab.
So I thought HN could be a nice place to start scraping. This is pretty useful as I keep checking on HN quite a few times during the whole day, having a sorted view for posts helps me read the interesting stuff first ^_^
Also a friend pointed out, it is particularly useful in the morning too check on interesting posts, which could have gone buried while you were sleeping!
How'd you do it?
Pretty simple! The code's up on
GitHub.
As I had mentioned before take a look at
Beautiful Soup and see how you can go about scraping the relevant data.
Once you are done with this, rest is just simple python script to combine the scraped data.
Thanks to
Bootstrap for the minimal UI.
Make ajax calls to fetch the data.
That's it.
Feel free to
Fork It.

#include <avr/eeprom.h>
This header file declares the interface to some simple library routines suitable for handling the data EEPROM contained in the AVR microcontrollers. The implementation uses a simple polled mode interface. Applications that require interrupt-controlled EEPROM access to ensure that no time will be wasted in spinloops will have to deploy their own implementation.
As these functions modify IO registers, they are known to be non-reentrant. If any of these functions are used from both, standard and interrupt context, the applications must ensure proper protection (e.g. by disabling interrupts before accessing them).
All write functions force erase_and_write programming mode.

Spiceworld -- Despite the spicy title, it's a rather vanilla movie, all things considered. If you're not a fan of the Girls, let me save you an hour and a half of saffron: don't waste your thyme on this one. However, if you don't hate them, or (like me) you think they're just plain savory, some sage advice is to cumin get it while it's still hot... due to chili reviews by cloves-minded critics, I cayenne see this bay-sically good-hearted flick tarragon from theaters before too long, parsley because the anti-Spice movement is inexplicably strong these days. The plot (what little there is), doesn't have too many leeks in it, and follows the girls through a series of capers they experience on the way to their first live show (which will turn out to be a lemon if the villain and his kelpers get their way). Peppered with silliness and grrl power, I was really arrow rooting for Our Heroes by the end of the movie. In particularly odd moments, Roger Moore shows his salt and earns his celery in an odd turn that most closely resembles a particular James Bond villain, anise no surprise when he shows up feeding a pig with a baby bottle. Throwing caraway, the Girls' on-screen manager is so hilariously bitter and uptight that one would expect him to bleed vinegar. Dill, despite some shortcomings (none of the humor was laugh-out-loud funny), it's clear the girls fenneled all they could (and they mint what they said) into their project, and while it mace seem strange to some, I found their enthusiasm suited me to a tea. Soy sue me, I liked it.
Overall, though I'm destined not to curry favor from others for this review, I'd gingerly recommend this movie, if for no other reason than it's allspice, and kept a goofy smile on my face the whole time. Cassia later.
