The Internets Election
One re-occuring theme in modern history is man vs machine. The bronze age, the industrial revolution, mathematics the technological age etc. Every so often, man makes such breakthrough in learning that it’s almost beyond his capacity to fully understand the new world in which he lives.
Usually this gap in understanding shows up in war. The Manhattan Project was a dream project for any ambitious physicist until they stepped back to really understand the scope of what they created.
Fast forward to today.
It’s been an interesting time to be in tech. This election cycle was…interesting. I’m not going to get into politics, but rather the way news and data is being weaponized. I don’t think many people realize how big automation and bots really are. I know I didn’t until I worked in digital publishing and learned about programatic sales, automated bidding and the scope of user tracking. Think those posts in the comment section are from real people? It’s becoming increasingly likely they are automated or paid trolls.
I didn’t always care about privacy. I wasn’t doing anything illegal, what should i worry about? But the amount of information that is available is staggering. This information can work in subtle ways. Someone knows that you’re looking for a plane ticket, and probably also the days you really want to travel, they are probably charging you a premium for your ticket, see Vitaly Tsyvinski’s excellent travel app. Or alerting potential employers that you are pregnant, or have small kids and making a judgement on your ability to contribute to the company before you even have an interview, or that you may have health issues that you prefer to keep private. Soon, employers will have an insane amount of data about applicants. I can’t imagine the repercussions.
This election cycle saw a record amount of buzz around fake news, foreign actors and email dumps. Not to mention connected devices taking down some of the most robust websites on the planet. It’s one thing when the internet explodes and gives us the crying Michael Jordan meme and occassional corporate email hack that spills all of Hollywoods gossip. But we may be moving past such rather innocent uses of its power, and I’m not even sure if there’s anything we can do to stop it.

Hierarch Kekropus:
The Giants used the Kamael as soldiers in the war, particularly our three great Kamael heroes, Harkilgamed, Katenar and Rodenpicular.
Each wielded a special weapon against the forces of Einhasad, and they fought well, even forcing the goddess an dher nine daughters
to retreat after being seriously injured. Thanks to their help, the Giants even captured Einhasad's castle.
They believed that the war had been won, but that was not the case. Beside herself with rage, Einhasad struck the capital city of the
Giants, Grande Perion, with the Hammer of the Stars. Fireballs fell from the heavens, destroying the first empire of the Giants.
Einhasad's daughters hunted the few survivors.
In the midst of this chaos, the Giant who was in charge of developing the Kamael sealed both the surviving Kamael and Arviterre
Laboratory to hide it from Einhasad. His hope was that one day, the descendants of those Kamael would prove a poison dagger that would
ultimately destroy the gods. His plan depended on the seal eventually being removed, but with most of the Giants dead or in hiding, we
were forgotten by the world...

library for calibrating and calculating GOEL370 oxygen sensor I needed to log these sensors in an existing CAN BUS setup and made my own amplifier.
No dependency found
g370_calbr(word in an) return word
This function assumes 20.95% oxygen concentration and returns the calibrating value. Call this one when your sensor breathes well ventilated air. Store the calibration value for use with the g370_ox() function.
g370_ox(word in an, word in calibr) return word
This function takes the word output of the D/A converter (0..1023) and the calibration value it returns a word value of the oxygen concentration in % * 100. So if the oxygen concentration is 21%, the function returns 2100.

Run Lola Run
**** (out of four)
Written and Directed by Tom Tykwer
Starring: Franka Potente as Lola Moritz Bleibtreu as Manni Herbert Knaup as Lolas Vater Nina Petri as Jutta Hansen
Run Lola Run could have been the new Pulp Fiction. It breathed life and electricity into a genre that seemed dead, or to most people, didn't even know existed. To write about it is to remember it's pulse, it's quick, lightning like photography and sound that rarely stopped, only to catch it's breath, then moved and ran, ran, ran - until at the end of the movie you were exhausted. As odd or cliche as this may sound, I left the theater catching my breath - feeling awkward that I was walking home rather than running.
Set to techno music, a rhythmic force of dance and action, the movie was paced like a cheetah running after it's prey. To sit still to it seemed unnatural. It blends animation, violence, love, revelation and hysterical action in an 85 minute movie. Five minutes of Lola is more entertaining than two hours of any recent Hollywood action film.  Lola runs to help him, thinking up different ways to get the money and avoiding pitfalls. Lola is a wonderful character, a new heroine that stands up to old female cliches, screams and shatters them.
Along the way, we see how split-second decisions and actions affect the rest of our lives. A boy offers to sell Lola his bike while she runs. She refuses, then immediately see several snapshots of him being mugged, beaten up, pity taken on him by a woman, and getting married to her. Tykwer makes a convincing life in the span of ten pictures. Snap, snap, snap, snap is your life. Depressing.
This is style merging effortlessly with substance. You couldn't have one without the other; the plot would die without Tykwer's speed-induced direction. But the direction is fun and plausible, instead of being a headache, because the setup presents a good life-or-death situation. It wastes no time to grab in an audience. Anything that seems out of place 0r silly is ignored because the movie goes too quickly to realize what is happening. Snap, snap, snap and the story jumps from a person who tells Lola to "Fuck Off" and then shows that woman's life.
That the movie wasn't more of a success in America surprises me. It is young and paced towards the 15-30 crowd, marketing's money darlings, the same crowd that producers created half of the past ten years of movies for. It offered many of the same qualities that made Pulp Fiction such a breakout. It was new, or seemed new anyway, with a direction and flash that inspired countless filmmakers to make direct photocopies. Audiences didn't seem to mind either, making Pulp Fiction and it's subsequent ripoffs lots of money. Lola also seemed to be fresh, in a different sort of way, but still fresh.
While it was a foreign film, complete with American-hated subtitles, this could have been overcome with a wide release and any sort of marketing campaign. Just a few trailers could have sparked interested. The success of this film was due solely to work of mouth. It played in independent theaters (the one I saw it in offered pillows to replace the dilapidated seat cushions). However, Lola wasn't given a wide release and suffered. What could have been a Blair Witch Project, was instead made into an Afterlife.

| PERLFAQ5(1) | Perl Programmers Reference Guide | PERLFAQ5(1) |
You might like to read Mark Jason Dominus's "Suffering From Buffering" at <http://perl.plover.com/FAQs/Buffering.html> .
Perl normally buffers output so it doesn't make a system call for every bit of output. By saving up output, it makes fewer expensive system calls. For instance, in this little bit of code, you want to print a dot to the screen for every line you process to watch the progress of your program. Instead of seeing a dot for every line, Perl buffers the output and you have a long wait before you see a row of 50 dots all at once:
# long wait, then row of dots all at once while( <> ) { print "."; print "\n" unless ++$count % 50; #... expensive line processing operations }
To get around this, you have to unbuffer the output filehandle, in this case, "STDOUT". You can set the special variable $| to a true value (mnemonic: making your filehandles "piping hot"):
$|++; # dot shown immediately while( <> ) { print "."; print "\n" unless ++$count % 50; #... expensive line processing operations }
The $| is one of the per-filehandle special variables, so each filehandle has its own copy of its value. If you want to merge standard output and standard error for instance, you have to unbuffer each (although STDERR might be unbuffered by default):
{ my $previous_default = select(STDOUT); # save previous default $|++; # autoflush STDOUT select(STDERR); $|++; # autoflush STDERR, to be sure select($previous_default); # restore previous default } # now should alternate . and + while( 1 ) { sleep 1; print STDOUT "."; print STDERR "+"; print STDOUT "\n" unless ++$count % 25; }
Besides the $| special variable, you can use "binmode" to give your filehandle a ":unix" layer, which is unbuffered:
binmode( STDOUT, ":unix" ); while( 1 ) { sleep 1; print "."; print "\n" unless ++$count % 50; }
For more information on output layers, see the entries for "binmode" and open in perlfunc, and the PerlIO module documentation.
If you are using IO::Handle or one of its subclasses, you can call the "autoflush" method to change the settings of the filehandle:
use IO::Handle; open my( $io_fh ), ">", "output.txt"; $io_fh->autoflush(1);
The IO::Handle objects also have a "flush" method. You can flush the buffer any time you want without auto-buffering
$io_fh->flush;
The basic idea of inserting, changing, or deleting a line from a text file involves reading and printing the file to the point you want to make the change, making the change, then reading and printing the rest of the file. Perl doesn't provide random access to lines (especially since the record input separator, $/, is mutable), although modules such as Tie::File can fake it.
A Perl program to do these tasks takes the basic form of opening a file, printing its lines, then closing the file:
open my $in, '<', $file or die "Can't read old file: $!"; open my $out, '>', "$file.new" or die "Can't write new file: $!"; while( <$in> ) { print $out $_; } close $out;
Within that basic form, add the parts that you need to insert, change, or delete lines.
To prepend lines to the beginning, print those lines before you enter the loop that prints the existing lines.
open my $in, '<', $file or die "Can't read old file: $!"; open my $out, '>', "$file.new" or die "Can't write new file: $!"; print $out "# Add this line to the top\n"; # <--- HERE'S THE MAGIC while( <$in> ) { print $out $_; } close $out;
To change existing lines, insert the code to modify the lines inside the "while" loop. In this case, the code finds all lowercased versions of "perl" and uppercases them. The happens for every line, so be sure that you're supposed to do that on every line!
open my $in, '<', $file or die "Can't read old file: $!"; open my $out, '>', "$file.new" or die "Can't write new file: $!"; print $out "# Add this line to the top\n"; while( <$in> ) { s/\b(perl)\b/Perl/g; print $out $_; } close $out;
To change only a particular line, the input line number, $., is useful. First read and print the lines up to the one you want to change. Next, read the single line you want to change, change it, and print it. After that, read the rest of the lines and print those:
while( <$in> ) { # print the lines before the change print $out $_; last if $. == 4; # line number before change } my $line = <$in>; $line =~ s/\b(perl)\b/Perl/g; print $out $line; while( <$in> ) { # print the rest of the lines print $out $_; }
To skip lines, use the looping controls. The "next" in this example skips comment lines, and the "last" stops all processing once it encounters either "__END__" or "__DATA__".
while( <$in> ) { next if /^\s+#/; # skip comment lines last if /^__(END|DATA)__$/; # stop at end of code marker print $out $_; }
Do the same sort of thing to delete a particular line by using "next" to skip the lines you don't want to show up in the output. This example skips every fifth line:
while( <$in> ) { next unless $. % 5; print $out $_; }
If, for some odd reason, you really want to see the whole file at once rather than processing line-by-line, you can slurp it in (as long as you can fit the whole thing in memory!):
open my $in, '<', $file or die "Can't read old file: $!" open my $out, '>', "$file.new" or die "Can't write new file: $!"; my $content = do { local $/; <$in> }; # slurp! # do your magic here print $out $content;
Modules such as Path::Tiny and Tie::File can help with that too. If you can, however, avoid reading the entire file at once. Perl won't give that memory back to the operating system until the process finishes.
You can also use Perl one-liners to modify a file in-place. The following changes all 'Fred' to 'Barney' in inFile.txt, overwriting the file with the new contents. With the "-p" switch, Perl wraps a "while" loop around the code you specify with "-e", and "-i" turns on in-place editing. The current line is in $_. With "-p", Perl automatically prints the value of $_ at the end of the loop. See perlrun for more details.
perl -pi -e 's/Fred/Barney/' inFile.txt
To make a backup of "inFile.txt", give "-i" a file extension to add:
perl -pi.bak -e 's/Fred/Barney/' inFile.txt
To change only the fifth line, you can add a test checking $., the input line number, then only perform the operation when the test passes:
perl -pi -e 's/Fred/Barney/ if $. == 5' inFile.txt
To add lines before a certain line, you can add a line (or lines!) before Perl prints $_:
perl -pi -e 'print "Put before third line\n" if $. == 3' inFile.txt
You can even add a line to the beginning of a file, since the current line prints at the end of the loop:
perl -pi -e 'print "Put before first line\n" if $. == 1' inFile.txt
To insert a line after one already in the file, use the "-n" switch. It's just like "-p" except that it doesn't print $_ at the end of the loop, so you have to do that yourself. In this case, print $_ first, then print the line that you want to add.
perl -ni -e 'print; print "Put after fifth line\n" if $. == 5' inFile.txt
To delete lines, only print the ones that you want.
perl -ni -e 'print if /d/' inFile.txt
Conceptually, the easiest way to count the lines in a file is to simply read them and count them:
my $count = 0; while( <$fh> ) { $count++; }
You don't really have to count them yourself, though, since Perl already does that with the $. variable, which is the current line number from the last filehandle read:
1 while( <$fh> ); my $count = $.;
If you want to use $., you can reduce it to a simple one-liner, like one of these:
% perl -lne '} print $.; {' file % perl -lne 'END { print $. }' file
Those can be rather inefficient though. If they aren't fast enough for you, you might just read chunks of data and count the number of newlines:
my $lines = 0; open my($fh), '<:raw', $filename or die "Can't open $filename: $!"; while( sysread $fh, $buffer, 4096 ) { $lines += ( $buffer =~ tr/\n// ); } close $fh;
However, that doesn't work if the line ending isn't a newline. You might change that "tr///" to a "s///" so you can count the number of times the input record separator, $/, shows up:
my $lines = 0; open my($fh), '<:raw', $filename or die "Can't open $filename: $!"; while( sysread $fh, $buffer, 4096 ) { $lines += ( $buffer =~ s|$/||g; ); } close $fh;
If you don't mind shelling out, the "wc" command is usually the fastest, even with the extra interprocess overhead. Ensure that you have an untainted filename though:
#!perl -T $ENV{PATH} = undef; my $lines; if( $filename =~ /^([0-9a-z_.]+)\z/ ) { $lines = `/usr/bin/wc -l $1` chomp $lines; }
The easiest conceptual solution is to count the lines in the file then start at the beginning and print the number of lines (minus the last N) to a new file.
Most often, the real question is how you can delete the last N lines without making more than one pass over the file, or how to do it without a lot of copying. The easy concept is the hard reality when you might have millions of lines in your file.
One trick is to use File::ReadBackwards, which starts at the end of the file. That module provides an object that wraps the real filehandle to make it easy for you to move around the file. Once you get to the spot you need, you can get the actual filehandle and work with it as normal. In this case, you get the file position at the end of the last line you want to keep and truncate the file to that point:
use File::ReadBackwards; my $filename = 'test.txt'; my $Lines_to_truncate = 2; my $bw = File::ReadBackwards->new( $filename ) or die "Could not read backwards in [$filename]: $!"; my $lines_from_end = 0; until( $bw->eof or $lines_from_end == $Lines_to_truncate ) { print "Got: ", $bw->readline; $lines_from_end++; } truncate( $filename, $bw->tell );
The File::ReadBackwards module also has the advantage of setting the input record separator to a regular expression.
You can also use the Tie::File module which lets you access the lines through a tied array. You can use normal array operations to modify your file, including setting the last index and using "splice".
# ... { local($^I, @ARGV) = ('.orig', glob("*.c")); while (<>) { if ($. == 1) { print "This line should appear at the top of each file\n"; } s/\b(p)earl\b/${1}erl/i; # Correct typos, preserving case print; close ARGV if eof; # Reset $. } } # $^I and @ARGV return to their old values here
This block modifies all the ".c" files in the current directory, leaving a backup of the original data from each file in a new ".c.orig" file.
Use the File::Copy module. It comes with Perl and can do a true copy across file systems, and it does its magic in a portable fashion.
use File::Copy; copy( $original, $new_copy ) or die "Copy failed: $!";
If you can't use File::Copy, you'll have to do the work yourself: open the original file, open the destination file, then print to the destination file as you read the original. You also have to remember to copy the permissions, owner, and group to the new file.
open my $tmp, '+>', undef or die $!;
Otherwise, you can use the File::Temp module.
use File::Temp qw/ tempfile tempdir /; my $dir = tempdir( CLEANUP => 1 ); ($fh, $filename) = tempfile( DIR => $dir ); # or if you don't need to know the filename my $fh = tempfile( DIR => $dir );
The File::Temp has been a standard module since Perl 5.6.1. If you don't have a modern enough Perl installed, use the "new_tmpfile" class method from the IO::File module to get a filehandle opened for reading and writing.
If you're committed to creating a temporary file by hand, use the process ID and/or the current time-value. If you need to have many temporary files in one process, use a counter:
BEGIN { use Fcntl; use File::Spec; my $temp_dir = File::Spec->tmpdir(); my $file_base = sprintf "%d-%d-0000", $$, time; my $base_name = File::Spec->catfile($temp_dir, $file_base); sub temp_file { my $fh; my $count = 0; until( defined(fileno($fh)) || $count++ > 100 ) { $base_name =~ s/-(\d+)$/"-" . (1 + $1)/e; # O_EXCL is required for security reasons. sysopen $fh, $base_name, O_WRONLY|O_EXCL|O_CREAT; } if( defined fileno($fh) ) { return ($fh, $base_name); } else { return (); } } }
Here is a sample chunk of code to break up and put back together again some fixed-format input lines, in this case from the output of a normal, Berkeley-style ps:
# sample input line: # 15158 p5 T 0:00 perl /home/tchrist/scripts/now-what my $PS_T = 'A6 A4 A7 A5 A*'; open my $ps, '-|', 'ps'; print scalar <$ps>; my @fields = qw( pid tt stat time command ); while (<$ps>) { my %process; @process{@fields} = unpack($PS_T, $_); for my $field ( @fields ) { print "$field: <$process{$field}>\n"; } print 'line=', pack($PS_T, @process{@fields} ), "\n"; }
We've used a hash slice in order to easily handle the fields of each row. Storing the keys in an array makes it easy to operate on them as a group or loop over them with "for". It also avoids polluting the program with global variables and using symbolic references.
open my $fh, $file_name; open local $fh, $file_name; print $fh "Hello World!\n"; process_file( $fh );
If you like, you can store these filehandles in an array or a hash. If you access them directly, they aren't simple scalars and you need to give "print" a little help by placing the filehandle reference in braces. Perl can only figure it out on its own when the filehandle reference is a simple scalar.
my @fhs = ( $fh1, $fh2, $fh3 ); for( $i = 0; $i <= $#fhs; $i++ ) { print {$fhs[$i]} "just another Perl answer, \n"; }
Before perl5.6, you had to deal with various typeglob idioms which you may see in older code.
open FILE, "> $filename"; process_typeglob( *FILE ); process_reference( \*FILE ); sub process_typeglob { local *FH = shift; print FH "Typeglob!" } sub process_reference { local $fh = shift; print $fh "Reference!" }
If you want to create many anonymous handles, you should check out the Symbol or IO::Handle modules.
$fh = SOME_FH; # bareword is strict-subs hostile $fh = "SOME_FH"; # strict-refs hostile; same package only $fh = *SOME_FH; # typeglob $fh = \*SOME_FH; # ref to typeglob (bless-able) $fh = *SOME_FH{IO}; # blessed IO::Handle from *SOME_FH typeglob
Or, you can use the "new" method from one of the IO::* modules to create an anonymous filehandle and store that in a scalar variable.
use IO::Handle; # 5.004 or higher my $fh = IO::Handle->new();
Then use any of those as you would a normal filehandle. Anywhere that Perl is expecting a filehandle, an indirect filehandle may be used instead. An indirect filehandle is just a scalar variable that contains a filehandle. Functions like "print", "open", "seek", or the "<FH>" diamond operator will accept either a named filehandle or a scalar variable containing one:
($ifh, $ofh, $efh) = (*STDIN, *STDOUT, *STDERR); print $ofh "Type it: "; my $got = <$ifh> print $efh "What was that: $got";
If you're passing a filehandle to a function, you can write the function in two ways:
sub accept_fh { my $fh = shift; print $fh "Sending to indirect filehandle\n"; }
Or it can localize a typeglob and use the filehandle directly:
sub accept_fh { local *FH = shift; print FH "Sending to localized filehandle\n"; }
Both styles work with either objects or typeglobs of real filehandles. (They might also work with strings under some circumstances, but this is risky.)
accept_fh(*STDOUT); accept_fh($handle);
In the examples above, we assigned the filehandle to a scalar variable before using it. That is because only simple scalar variables, not expressions or subscripts of hashes or arrays, can be used with built-ins like "print", "printf", or the diamond operator. Using something other than a simple scalar variable as a filehandle is illegal and won't even compile:
my @fd = (*STDIN, *STDOUT, *STDERR); print $fd[1] "Type it: "; # WRONG my $got = <$fd[0]> # WRONG print $fd[2] "What was that: $got"; # WRONG
With "print" and "printf", you get around this by using a block and an expression where you would place the filehandle:
print { $fd[1] } "funny stuff\n"; printf { $fd[1] } "Pity the poor %x.\n", 3_735_928_559; # Pity the poor deadbeef.
That block is a proper block like any other, so you can put more complicated code there. This sends the message out to one of two places:
my $ok = -x "/bin/cat"; print { $ok ? $fd[1] : $fd[2] } "cat stat $ok\n"; print { $fd[ 1+ ($ok || 0) ] } "cat stat $ok\n";
This approach of treating "print" and "printf" like object methods calls doesn't work for the diamond operator. That's because it's a real operator, not just a function with a comma-less argument. Assuming you've been storing typeglobs in your structure as we did above, you can use the built-in function named "readline" to read a record just as "<>" does. Given the initialization shown above for @fd, this would work, but only because readline() requires a typeglob. It doesn't work with objects or strings, which might be a bug we haven't fixed yet.
$got = readline($fd[0]);
Let it be noted that the flakiness of indirect filehandles is not related to whether they're strings, typeglobs, objects, or anything else. It's the syntax of the fundamental operators. Playing the object game doesn't help you at all here.
Since Perl 5.8.0 a file handle referring to a string can be created by calling open with a reference to that string instead of the filename. This file handle can then be used to read from or write to the string:
open(my $fh, '>', \$string) or die "Could not open string for writing"; print $fh "foo\n"; print $fh "bar\n"; # $string now contains "foo\nbar\n" open(my $fh, '<', \$string) or die "Could not open string for reading"; my $x = <$fh>; # $x now contains "foo\n"
With older versions of Perl, the IO::String module provides similar functionality.
If you want to "write" into a string, you just have to <open> a filehandle to a string, which Perl has been able to do since Perl 5.6:
open FH, '>', \my $string; write( FH );
Since you want to be a good programmer, you probably want to use a lexical filehandle, even though formats are designed to work with bareword filehandles since the default format names take the filehandle name. However, you can control this with some Perl special per-filehandle variables: $^, which names the top-of-page format, and $~ which shows the line format. You have to change the default filehandle to set these variables:
open my($fh), '>', \my $string; { # set per-filehandle variables my $old_fh = select( $fh ); $~ = 'ANIMAL'; $^ = 'ANIMAL_TOP'; select( $old_fh ); } format ANIMAL_TOP = ID Type Name . format ANIMAL = @## @<<< @<<<<<<<<<<<<<< $id, $type, $name .
Although write can work with lexical or package variables, whatever variables you use have to scope in the format. That most likely means you'll want to localize some package variables:
{ local( $id, $type, $name ) = qw( 12 cat Buster ); write( $fh ); } print $string;
There are also some tricks that you can play with "formline" and the accumulator variable $^A, but you lose a lot of the value of formats since "formline" won't handle paging and so on. You end up reimplementing formats when you use them.
You can use Number::Format to separate places in a number. It handles locale information for those of you who want to insert full stops instead (or anything else that they want to use, really).
This subroutine will add commas to your number:
sub commify { local $_ = shift; 1 while s/^([-+]?\d+)(\d{3})/$1,$2/; return $_; }
This regex from Benjamin Goldberg will add commas to numbers:
s/(^[-+]?\d+?(?=(?>(?:\d{3})+)(?!\d))|\G\d{3}(?=\d))/$1,/g;
It is easier to see with comments:
s/( ^[-+]? # beginning of number. \d+? # first digits before first comma (?= # followed by, (but not included in the match) : (?>(?:\d{3})+) # some positive multiple of three digits. (?!\d) # an *exact* multiple, not x * 3 + 1 or whatever. ) | # or: \G\d{3} # after the last group, get three digits (?=\d) # but they have to have more digits after them. )/$1,/xg;
Within Perl, you may use this directly:
$filename =~ s{ ^ ~ # find a leading tilde ( # save this in $1 [^/] # a non-slash character * # repeated 0 or more times (0 means me) ) }{ $1 ? (getpwnam($1))[7] : ( $ENV{HOME} || $ENV{LOGDIR} ) }ex;
open my $fh, '+>', '/path/name'; # WRONG (almost always)
Whoops. You should instead use this, which will fail if the file doesn't exist:
open my $fh, '+<', '/path/name'; # open for update
Using ">" always clobbers or creates. Using "<" never does either. The "+" doesn't change this.
Here are examples of many kinds of file opens. Those using "sysopen" all assume that you've pulled in the constants from Fcntl:
use Fcntl;
To open file for reading:
open my $fh, '<', $path or die $!; sysopen my $fh, $path, O_RDONLY or die $!;

To open file for writing, create new file, file must not exist:
sysopen my $fh, $path, O_WRONLY|O_EXCL|O_CREAT or die $!; sysopen my $fh, $path, O_WRONLY|O_EXCL|O_CREAT, 0666 or die $!;

To open file for appending, file must exist:
sysopen my $fh, $path, O_WRONLY|O_APPEND or die $!;
To open file for update, file must exist:
open my $fh, '+<', $path or die $!; sysopen my $fh, $path, O_RDWR or die $!;

To open file for update, file must not exist:
sysopen my $fh, $path, O_RDWR|O_EXCL|O_CREAT or die $!; sysopen my $fh, $path, O_RDWR|O_EXCL|O_CREAT, 0666 or die $!;
To open a file without blocking, creating if necessary:
sysopen my $fh, '/foo/somefile', O_WRONLY|O_NDELAY|O_CREAT or die "can't open /foo/somefile: $!":
Be warned that neither creation nor deletion of files is guaranteed to be an atomic operation over NFS. That is, two processes might both successfully create or unlink the same file! Therefore O_EXCL isn't as exclusive as you might wish.
See also perlopentut.
To get around this, either upgrade to Perl v5.6.0 or later, do the glob yourself with readdir() and patterns, or use a module like File::Glob, one that doesn't use the shell to do globbing.
The special two-argument form of Perl's open() function ignores trailing blanks in filenames and infers the mode from certain leading characters (or a trailing "|"). In older versions of Perl this was the only version of open() and so it is prevalent in old code and books.
Unless you have a particular reason to use the two-argument form you should use the three-argument form of open() which does not treat any characters in the filename as special.
open my $fh, "<", " file "; # filename is " file " open my $fh, ">", ">file"; # filename is ">file"
rename($old, $new) or system("mv", $old, $new);
It may be more portable to use the File::Copy module instead. You just copy to the new file to the new name (checking return values), then delete the old one. This isn't really the same semantically as a "rename()", which preserves meta-information like permissions, timestamps, inode info, etc.
Two potentially non-obvious but traditional flock semantics are that it waits indefinitely until the lock is granted, and that its locks are merely advisory. Such discretionary locks are more flexible, but offer fewer guarantees. This means that files locked with flock() may be modified by programs that do not also use flock(). Cars that stop for red lights get on well with each other, but not with cars that don't stop for red lights. See the perlport manpage, your port's specific documentation, or your system-specific local manpages for details. It's best to assume traditional behavior if you're writing portable programs. (If you're not, you should as always feel perfectly free to write for your own system's idiosyncrasies (sometimes called "features"). Slavish adherence to portability concerns shouldn't get in the way of your getting your job done.)
For more information on file locking, see also "File Locking" in perlopentut if you have it (new for 5.6).
sleep(3) while -e 'file.lock'; # PLEASE DO NOT USE open my $lock, '>', 'file.lock'; # THIS BROKEN CODE
This is a classic race condition: you take two steps to do something which must be done in one. That's why computer hardware provides an atomic test-and-set instruction. In theory, this "ought" to work:
sysopen my $fh, "file.lock", O_WRONLY|O_EXCL|O_CREAT or die "can't open file.lock: $!";
except that lamentably, file creation (and deletion) is not atomic over NFS, so this won't work (at least, not every time) over the net. Various schemes involving link() have been suggested, but these tend to involve busy-wait, which is also less than desirable.

Here's a much better web-page hit counter:
$hits = int( (time() - 850_000_000) / rand(1_000) );
If the count doesn't impress your friends, then the code might. :-)
If you know you are only going to use a system that does correctly implement appending (i.e. not Win32) then you can omit the "seek" from the code in the previous answer.
If you know you are only writing code to run on an OS and filesystem that does implement append mode correctly (a local filesystem on a modern Unix for example), and you keep the file in block-buffered mode and you write less than one buffer-full of output between each manual flushing of the buffer then each bufferload is almost guaranteed to be written to the end of the file in one chunk without getting intermingled with anyone else's output. You can also use the "syswrite" function which is simply a wrapper around your system's write(2) system call.
There is still a small theoretical chance that a signal will interrupt the system-level "write()" operation before completion. There is also a possibility that some STDIO implementations may call multiple system level "write()"s even if the buffer was empty to start. There may be some systems where this probability is reduced to zero, and this is not a concern when using ":perlio" instead of your system's STDIO.
perl -i -pe 's{window manager}{window mangler}g' /usr/bin/emacs
However, if you have fixed sized records, then you might do something more like this:
my $RECSIZE = 220; # size of record, in bytes my $recno = 37; # which record to update open my $fh, '+<', 'somewhere' or die "can't update somewhere: $!"; seek $fh, $recno * $RECSIZE, 0; read $fh, $record, $RECSIZE == $RECSIZE or die "can't read record $recno: $!"; # munge the record seek $fh, -$RECSIZE, 1; print $fh $record; close $fh;
Locking and error checking are left as an exercise for the reader. Don't forget them or you'll be quite sorry.
Here's an example:
my $write_secs = (stat($file))[9]; printf "file %s updated at %s\n", $file, scalar localtime($write_secs);
If you prefer something more legible, use the File::stat module (part of the standard distribution in version 5.004 and later):
# error checking left as an exercise for reader. use File::stat; use Time::localtime; my $date_string = ctime(stat($file)->mtime); print "file $file updated at $date_string\n";
The POSIX::strftime() approach has the benefit of being, in theory, independent of the current locale. See perllocale for details.
if (@ARGV < 2) { die "usage: cptimes timestamp_file other_files ...\n"; } my $timestamp = shift; my($atime, $mtime) = (stat($timestamp))[8,9]; utime $atime, $mtime, @ARGV;
Error checking is, as usual, left as an exercise for the reader.
The perldoc for utime also has an example that has the same effect as touch(1) on files that already exist.
Certain file systems have a limited ability to store the times on a file at the expected level of precision. For example, the FAT and HPFS filesystem are unable to create dates on files with a finer granularity than two seconds. This is a limitation of the filesystems, not of utime().
If you only have to do this once, you can print individually to each filehandle.
for my $fh ($fh1, $fh2, $fh3) { print $fh "whatever\n" }
open my $input, '<', $file or die "can't open $file: $!"; while (<$input>) { chomp; # do something with $_ } close $input or die "can't close $file: $!";
This is tremendously more efficient than reading the entire file into memory as an array of lines and then processing it one element at a time, which is often--if not almost always--the wrong approach. Whenever you see someone do this:
my @lines = <INPUT>;
You should think long and hard about why you need everything loaded at once. It's just not a scalable solution.
If you "mmap" the file with the File::Map module from CPAN, you can virtually load the entire file into a string without actually storing it in memory:
use File::Map qw(map_file); map_file my $string, $filename;
Once mapped, you can treat $string as you would any other string. Since you don't necessarily have to load the data, mmap-ing can be very fast and may not increase your memory footprint.
You might also find it more fun to use the standard Tie::File module, or the DB_File module's $DB_RECNO bindings, which allow you to tie an array to a file so that accessing an element of the array actually accesses the corresponding line in the file.
If you want to load the entire file, you can use the Path::Tiny module to do it in one simple and efficient step:
use Path::Tiny; my $all_of_it = path($filename)->slurp; # entire file in scalar my @all_lines = path($filename)->lines; # one line per element
Or you can read the entire file contents into a scalar like this:
my $var; { local $/; open my $fh, '<', $file or die "can't open $file: $!"; $var = <$fh>; }
That temporarily undefs your record separator, and will automatically close the file at block exit. If the file is already open, just use this:
my $var = do { local $/; <$fh> };
You can also use a localized @ARGV to eliminate the "open":
my $var = do { local( @ARGV, $/ ) = $file; <> };
For ordinary files you can also use the "read" function.
read( $fh, $var, -s $fh );
That third argument tests the byte size of the data on the $fh filehandle and reads that many bytes into the buffer $var.
Note that a blank line must have no blanks in it. Thus "fred\n \nstuff\n\n" is one paragraph, but "fred\n\nstuff\n\n" is two.
If your system supports the portable operating system programming interface (POSIX), you can use the following code, which you'll note turns off echo processing as well.
#!/usr/bin/perl -w use strict; $| = 1; for (1..4) { print "gimme: "; my $got = getone(); print "--> $got\n"; } exit; BEGIN { use POSIX qw(:termios_h); my ($term, $oterm, $echo, $noecho, $fd_stdin); my $fd_stdin = fileno(STDIN); $term = POSIX::Termios->new(); $term->getattr($fd_stdin); $oterm = $term->getlflag(); $echo = ECHO | ECHOK | ICANON; $noecho = $oterm & ~$echo; sub cbreak { $term->setlflag($noecho); $term->setcc(VTIME, 1); $term->setattr($fd_stdin, TCSANOW); } sub cooked { $term->setlflag($oterm); $term->setcc(VTIME, 0); $term->setattr($fd_stdin, TCSANOW); } sub getone { my $key = ''; cbreak(); sysread(STDIN, $key, 1); cooked(); return $key; } } END { cooked() }
The Term::ReadKey module from CPAN may be easier to use. Recent versions include also support for non-portable systems as well.
use Term::ReadKey; open my $tty, '<', '/dev/tty'; print "Gimme a char: "; ReadMode "raw"; my $key = ReadKey 0, $tty; ReadMode "normal"; printf "\nYou said %s, char number %03d\n", $key, ord $key;
You should also check out the Frequently Asked Questions list in comp.unix.* for things like this: the answer is essentially the same. It's very system-dependent. Here's one solution that works on BSD systems:
sub key_ready { my($rin, $nfd); vec($rin, fileno(STDIN), 1) = 1; return $nfd = select($rin,undef,undef,0); }
If you want to find out how many characters are waiting, there's also the FIONREAD ioctl call to be looked at. The h2ph tool that comes with Perl tries to convert C include files to Perl code, which can be "require"d. FIONREAD ends up defined as a function in the sys/ioctl.ph file:
require './sys/ioctl.ph'; $size = pack("L", 0); ioctl(FH, FIONREAD(), $size) or die "Couldn't call ioctl: $!\n"; $size = unpack("L", $size);
If h2ph wasn't installed or doesn't work for you, you can grep the include files by hand:
% grep FIONREAD /usr/include/*/* /usr/include/asm/ioctls.h:#define FIONREAD 0x541B
Or write a small C program using the editor of champions:
% cat > fionread.c #include <sys/ioctl.h> main() { printf("%#08x\n", FIONREAD); } ^D % cc -o fionread fionread.c % ./fionread 0x4004667f
And then hard-code it, leaving porting as an exercise to your successor.
$FIONREAD = 0x4004667f; # XXX: opsys dependent $size = pack("L", 0); ioctl(FH, $FIONREAD, $size) or die "Couldn't call ioctl: $!\n"; $size = unpack("L", $size);
FIONREAD requires a filehandle connected to a stream, meaning that sockets, pipes, and tty devices work, but not files.
seek($gw_fh, 0, 1);
The statement "seek($gw_fh, 0, 1)" doesn't change the current position, but it does clear the end-of-file condition on the handle, so that the next "<$gw_fh>" makes Perl try again to read something.
If that doesn't work (it relies on features of your stdio implementation), then you need something more like this:
for (;;) { for ($curpos = tell($gw_fh); <$gw_fh>; $curpos =tell($gw_fh)) { # search for some stuff and put it into files } # sleep for a while seek($gw_fh, $curpos, 0); # seek to where we had been }
If this still doesn't work, look into the "clearerr" method from IO::Handle, which resets the error and end-of-file states on the handle.
There's also a File::Tail module from CPAN.
open my $log, '>>', '/foo/logfile'; open STDERR, '>&', $log;
Or even with a literal numeric descriptor:
my $fd = $ENV{MHCONTEXTFD}; open $mhcontext, "<&=$fd"; # like fdopen(3S)
Note that "<&STDIN" makes a copy, but "<&=STDIN" makes an alias. That means if you close an aliased handle, all aliases become inaccessible. This is not true with a copied one.
Error checking, as always, has been left as an exercise for the reader.
use POSIX (); POSIX::close( $fd );
This should rarely be necessary, as the Perl "close()" function is to be used for things that Perl opened itself, even if it was a dup of a numeric descriptor as with "MHCONTEXT" above. But if you really have to, you may be able to do this:
require './sys/syscall.ph'; my $rc = syscall(SYS_close(), $fd + 0); # must force numeric die "can't sysclose $fd: $!" unless $rc == -1;
Or, just use the fdopen(3S) feature of "open()":
{ open my $fh, "<&=$fd" or die "Cannot reopen fd=$fd: $!"; close $fh; }
Either single-quote your strings, or (preferably) use forward slashes. Since all DOS and Windows versions since something like MS-DOS 2.0 or so have treated "/" and "\" the same in a path, you might as well use the one that doesn't clash with Perl--or the POSIX shell, ANSI C and C++, awk, Tcl, Java, or Python, just to mention a few. POSIX paths are more portable, too.
The executive summary: learn how your filesystem works. The permissions on a file say what can happen to the data in that file. The permissions on a directory say what can happen to the list of files in that directory. If you delete a file, you're removing its name from the directory (so the operation depends on the permissions of the directory, not of the file). If you try to write to the file, the permissions of the file govern whether you're allowed to.
Here's a reservoir-sampling algorithm from the Camel Book:
srand; rand($.) < 1 && ($line = $_) while <>;
This has a significant advantage in space over reading the whole file in. You can find a proof of this method in The Art of Computer Programming, Volume 2, Section 3.4.2, by Donald E. Knuth.
You can use the File::Random module which provides a function for that algorithm:
use File::Random qw/random_line/; my $line = random_line($filename);
Another way is to use the Tie::File module, which treats the entire file as an array. Simply access a random array element.
If you are seeing spaces between the elements of your array when you print the array, you are probably interpolating the array in double quotes:
my @animals = qw(camel llama alpaca vicuna); print "animals are: @animals\n";
It's the double quotes, not the "print", doing this. Whenever you interpolate an array in a double quote context, Perl joins the elements with spaces (or whatever is in $", which is a space by default):
animals are: camel llama alpaca vicuna
This is different than printing the array without the interpolation:
my @animals = qw(camel llama alpaca vicuna); print "animals are: ", @animals, "\n";
Now the output doesn't have the spaces between the elements because the elements of @animals simply become part of the list to "print":
animals are: camelllamaalpacavicuna
You might notice this when each of the elements of @array end with a newline. You expect to print one element per line, but notice that every line after the first is indented:
this is a line this is another line this is the third line
That extra space comes from the interpolation of the array. If you don't want to put anything between your array elements, don't use the array in double quotes. You can send it to print without them:
print @lines;
The File::Find module, which comes with Perl, does all of the hard work to traverse a directory structure. It comes with Perl. You simply call the "find" subroutine with a callback subroutine and the directories you want to traverse:
use File::Find; find( \&wanted, @directories ); sub wanted { # full path in $File::Find::name # just filename in $_ ... do whatever you want to do ... }
The File::Find::Closures, which you can download from CPAN, provides many ready-to-use subroutines that you can use with File::Find.
The File::Finder, which you can download from CPAN, can help you create the callback subroutine using something closer to the syntax of the "find" command-line utility:
use File::Find; use File::Finder; my $deep_dirs = File::Finder->depth->type('d')->ls->exec('rmdir','{}'); find( $deep_dirs->as_options, @places );
The File::Find::Rule module, which you can download from CPAN, has a similar interface, but does the traversal for you too:
use File::Find::Rule; my @files = File::Find::Rule->file() ->name( '*.pm' ) ->in( @INC );
If you have an empty directory, you can use Perl's built-in "rmdir". If the directory is not empty (so, with files or subdirectories), you either have to empty it yourself (a lot of work) or use a module to help you.
The File::Path module, which comes with Perl, has a "remove_tree" which can take care of all of the hard work for you:
use File::Path qw(remove_tree); remove_tree( @directories );
The File::Path module also has a legacy interface to the older "rmtree" subroutine.
To do the equivalent of "cp -R" (i.e. copy an entire directory tree recursively) in portable Perl, you'll either need to write something yourself or find a good CPAN module such as File::Copy::Recursive.

It also provides basic support for POSIX systems (e.g., OSX) but without any actual isolation, only resource usage reporting.
Shared Filesystem
The SharedFilesystem isolator can optionally be used on Linux hosts to enable modifications to each container’s view of the shared filesystem.
The modifications are specified in the ContainerInfo included in the
ExecutorInfo, either by a framework or by using the
--default_container_info
agent flag.
ContainerInfo specifies Volumes which map parts of the shared filesystem (host_path) into the container’s view of the filesystem (container_path), as read-write or read-only. The host_path can be absolute, in which case it will make the filesystem subtree rooted at host_path also accessible under container_path for each container. If host_path is relative then it is considered as a directory relative to the executor’s work directory. The directory will be created and permissions copied from the corresponding directory (which must exist) in the shared filesystem.
The primary use-case for this isolator is to selectively make parts of
the shared filesystem private to each container. For example, a
private “/tmp” directory can be achieved with host_path="tmp"
and
container_path="/tmp"
which will create a directory “tmp” inside the
executor’s work directory (mode 1777) and simultaneously mount it as
/tmp inside the container. This is transparent to processes running
inside the container. Containers will not be able to see the host’s
/tmp or any other container’s /tmp.
Pid Namespace
The Pid Namespace isolator can be used to isolate each container in a separate pid namespace with two main benefits:
Visibility: Processes running in the container (executor and descendants) are unable to see or signal processes outside the namespace.
Clean termination: Termination of the leading process in a pid namespace will result in the kernel terminating all other processes in the namespace.
The Launcher will use (2) during destruction of a container in preference to the freezer cgroup, avoiding known kernel issues related to freezing cgroups under OOM conditions.
/proc will be mounted for containers so tools such as ‘ps’ will work correctly.
Posix Disk Isolator
The Posix Disk isolator provides basic disk isolation. It is able to report the disk usage for each sandbox and optionally enforce the disk quota. It can be used on both Linux and OS X.
To enable the Posix Disk isolator, append disk/du
to the --isolation
flag when starting the agent.
By default, the disk quota enforcement is disabled. To enable it,
specify --enforce_container_disk_quota
when starting the agent.
The Posix Disk isolator reports disk usage for each sandbox by
periodically running the du
command. The disk usage can be retrieved
from the resource statistics endpoint (/monitor/statistics).
The interval between two du
s can be controlled by the agent flag
--container_disk_watch_interval
. For example,
--container_disk_watch_interval=1mins
sets the interval to be 1
minute. The default interval is 15 seconds.
XFS Disk Isolator
The XFS Disk isolator uses XFS project quotas to track the disk
space used by each container sandbox and to enforce the corresponding
disk space allocation. Write operations performed by tasks exceeding
their disk allocation will fail with an EDQUOT
error. The task
will not be terminated by the containerizer.
The XFS disk isolator is functionally similar to Posix Disk isolator
but avoids the cost of repeatedly running the du
. Though they will
not interfere with each other, it is not recommended to use them together.
To enable the XFS Disk isolator, append disk/xfs
to the --isolation
flag when starting the agent.
The XFS Disk isolator requires the sandbox directory to be located
on an XFS filesystem that is mounted with the pquota
option. There
is no need to configure
projects
or projid
files. The range of project IDs given to the --xfs_project_range
must not overlap any project IDs allocated for other uses.
The XFS disk isolator does not natively support an accounting-only mode
like that of the Posix Disk isolator. Quota enforcement can be disabled
by mounting the filesystem with the pqnoenforce
mount option.
The xfs_quota command can be used to show the current allocation of project IDs and quota. For example:
$ xfs_quota -x -c "report -a -n -L 5000 -U 1000"
To show which project a file belongs to, use the
xfs_io command
to display the fsxattr.projid
field. For example:
$ xfs_io -r -c stat /mnt/mesos/
Note that the Posix Disk isolator flags --enforce_container_disk_quota
,
--container_disk_watch_interval
and --enforce_container_disk_quota
do
not apply to the XFS Disk isolator.
Docker Runtime Isolator
The Docker Runtime isolator is used for supporting runtime
configurations from the docker image (e.g., Entrypoint/Cmd, Env,
etc.). This isolator is tied with --image_providers=docker
. If
--image_providers
contains docker
, this isolator must be used.
Otherwise, the agent will refuse to start.
To enable the Docker Runtime isolator, append docker/runtime
to the
--isolation
flag when starting the agent.
Currently, docker image default Entrypoint
, Cmd
, Env
, and WorkingDir
are
supported with docker runtime isolator. Users can specify CommandInfo
to
override the default Entrypoint
and Cmd
in the image (see below for
details). The CommandInfo
should be inside of either TaskInfo
or
ExecutorInfo
(depending on whether the task is a command task or uses a custom
executor, respectively).
Determine the Launch Command
If the user specifies a command in CommandInfo
, that will override the
default Entrypoint/Cmd in the docker image. Otherwise, we will use the
default Entrypoint/Cmd and append arguments specified in CommandInfo
accordingly. The details are explained in the following table.
Users can specify CommandInfo
including shell
, value
and
arguments
, which are represented in the first column of the table
below. 0
represents not specified
, while 1
represents
specified
. The first row is how Entrypoint
and Cmd
defined in
the docker image. All cells in the table, except the first column and
row, as well as cells labeled as Error
, have the first element
(i.e., /Entrypt[0]
) as executable, and the rest as appending
arguments.

The cgroups/net_cls
Isolator
The cgroups/net_cls isolator allows operators to provide network
performance isolation and network segmentation for containers within
a Mesos cluster. To enable the cgroups/net_cls isolator, append
cgroups/net_cls
to the --isolation
flag when starting the agent.
As the name suggests, the isolator enables the net_cls subsystem for
Linux cgroups and assigns a net_cls cgroup to each container launched
by the MesosContainerizer
. The objective of the net_cls subsystem
is to allow the kernel to tag packets originating from a container
with a 32-bit handle. These handles can be used by kernel modules such
as qdisc
(for traffic engineering) and net-filter
(for
firewall) to enforce network performance and security policies
specified by the operators. The policies, based on the net_cls
handles, can be specified by the operators through user-space tools
such as
tc
and iptables.
The 32-bit handle associated with a net_cls cgroup can be specified by
writing the handle to the net_cls.classid
file, present within the
net_cls cgroup. The 32-bit handle is of the form 0xAAAABBBB
, and
consists of a 16-bit primary handle 0xAAAA and a 16-bit secondary
handle 0xBBBB. You can read more about the use cases for the primary
and secondary handles in the Linux kernel documentation for
net_cls.
By default, the cgroups/net_cls isolator does not manage the net_cls
handles, and assumes the operator is going to manage/assign these
handles. To enable the management of net_cls handles by the
cgroups/net_cls isolator you need to specify a 16-bit primary handle,
of the form 0xAAAA, using the --cgroups_net_cls_primary_handle
flag at
agent startup.
Once a primary handle has been specified for an agent, for each
container the cgroups/net_cls isolator allocates a 16-bit secondary
handle. It then assigns the 32-bit combination of the primary and
secondary handle to the net_cls cgroup associated with the container
by writing to net_cls.classid
. The cgroups/net_cls isolator exposes
the assigned net_cls handle to operators by exposing the handle as
part of the ContainerStatus
—associated with any task running within
the container— in the agent’s /state endpoint.
The docker/volume
Isolator
This is described in a separate document.
The namespaces/ipc
Isolator
The IPC Namespace isolator can be used on Linux to place tasks in a distinct IPC namespace. The benefit of this is that any IPC objects created in the container will be automatically removed when the container is destroyed.
The network/cni
Isolator
This is described in a separate document.
The linux/capabilities
Isolator
This is described in a separate document.

You have agreed to help a roofer estimate the amount of material required to protect the surface of a roof from sun damage by computing the surface area of the roof that can be seen when viewed from directly above.
The geometry of a roof is defined by the vertices of the triangles that enclose the plane surfaces of the roof. The x
In an aerial view of a roof, one region of the roof can sometimes obscure a lower region. Only visible portions of the roof should be included in the total. For example, suppose you view a two-story building with a second floor that is smaller than the first floor. Obviously the area of the second floor's roof must be included in the total, but the visible surface area of the first floor's roof will not include the area directly underneath the second floor's roof.
The input consists of several test cases corresponding to roof descriptions. A test case begins with a line containing integers V
All coordinates are positive integers no greater than 100. No roof triangles are degenerate, and all pairs of roof triangles have disjoint interiors -- that is, they may touch but they will not overlap or intersect.
The last test case is followed by a line containing two zeroes.
For each test case, print a line containing the test case number (beginning with 1) followed by the total visible surface area of the roof, accurate to two fractional digits. Use the sample output format and print a blank line after each case.

WEIBO SPATIAL AND TEMPORAL DATA
By {{author.display_name}}{% if author contains 'chinese_name' %} ({{author.chinese_name}}){% endif %} on 26 may 2014
For the Digital Eternity Project, we queried the Weibo API during the period of Qing Ming festival. This traditional Chinese festival (清明节 Qīngmíng Jíe in Mandarin Chinese) also known as Ancestors’ Day held on April 5 this year. We collected about 245,000 messages created between April 1 and April 9 and localized in Shanghai. These messages aim to be analyzed for their content but they also represent a convenient dataset to explore the variation of the number of messages posted along the day across the city.
Therefore, based on the creation date of these messages, we could make the bar chart of the bottom portion, showing the number of messages per hour of the day.
As the messages are also localized, we could position them on a map of Shanghai to compare the activity registered in the different areas. Thus, we re-created a tessellation made with 4 km diameter cells centered on the 85 locations used to query the Weibo API. Each message was counted in the cell whose center was the closest to its GPS location. The top portion shows the resulting map without regard to their creation time.
Then we can combine these two informations, namely location and time, to explore the variation of activity in the various areas along the day. To see the localized activity along the day, you can mouse over the bars of the bar chart and the map will update according to the hour. It would have been as easy to create an animation that would play the 24 maps but we found that it was more exploration oriented to be able to play at will the differences between successive hours.
This visualization is built on two JavaScript libraries: D3.js for the bar chart and Mapbox.js for the maps. To learn more about how all the code works, a tutorial is available on our blog.


--- layout: resources title: Learning Programming short: learnprogramming permalink: /resources/learn-programming/ ---
Want to learn programming? Awesome! Here are a few resources to help you on your way to becoming a pro-grammer! We have resources to help beginner coders learn exactly what coding is, and how they can use it to help them out!
Coding can look super scary, and it definitely can be! Simply put, programming is becoming a professional problem solver: whether it's solving a math question, figuring out how to best convey a message, or making your wildest dreams your reality! All you need to do is explain what you want to do, to your computer.
There are two large elements to any sort of programming: logic
and syntax
. Logic
is the thought process behind your code, or a set of steps the computer will follow to solve your problem. Syntax
is the format this logic is placed in, very similar to grammar in any language.
Here are a few essential tools, no matter what language you're learning!
Here's a table of some of the most popular languages, though you certainly don't need to know all of them! Instead, pick 1 or 2 that fit what you're looking to make, and start from there. Plus, check out our sections in the sidebar for explanations and resources for each language!
One very common path is to learn Python, an object-oriented language, HTML, CSS, and Javascript. This is by no means the "correct" way to learn programming, but it covers a diverse set of languages, and can help you make almost anything!
| Language | Description | Difficulty | Used In |
|---|---|---|---|
| HTML and CSS | Hyper Text Markup Language is a markup language that is used to make content on websites, while Cascading StyleSheets is used to make that content pretty! HTML and CSS are the barebones of any website. | Easy | Website Design, Templating |
| Javascript | Javascript is a scripting language primarily designed for web interactions (like fancy buttons), but has evolved to be used almost anywhere! Many flavours of Javascript build on its core features, making it very versatile. | Medium | Website Design, Web Applications |
| Python | Python is a dynamic scripting language with very readable, English-like syntax, but also packs a punch with many features and libraries. Python is a great language to start with! | Medium | Scripting, Modelling, Machine Learning |
| Ruby | Ruby is an easily read, but powerful language with many uses in automation and web development. Ruby is often used with Rails to make web applications. | Medium | Scripting, Web Applications |
| Java | Java is a compiled, object-oriented language based off of C. Java code only needs to be written once to be used everywhere, through the Java Virtual Machine. Recently, it is also used in Android app development. | Hard | Client-Server Applications, Android Applications |
| C | C is a low-level, old, but still useful programming language that is the proverbial "grandfather" to most modern languages. It is still used today on low-level devices and programs. | Hard | Microcontrollers, Robotics, Operating Systems |
| C++ | C++ is an object-oriented variation of C designed to improve upon C. C++ works on most Operating Systems, making it a popular choice in application development. | Hard | Desktop Applications, Servers, Hardware |
| C# | C# is an object-oriented variation of C developed by Microsoft and designed to extend C's capabilities. As a result, it is often used with Windows products. | Hard | Windows Applications, Games |
HTML (Hyper Text Markup Language) and CSS (Cascading StyleSheets) are the core foundation to any website on the internet. HTML is used to structure and write content, such as this paragraph; CSS is then used to make this paragraph look good, through colours, fonts, spacing, and many others. While HTML and CSS aren't "real" programming languages, they're a good start into making awesome things with computers, and are a super useful skill to have.

Programming
The chip is so small it cannot use a SPI interface but uses instead the TPI (Tiny Programming Interface). For the AVR mkII programmer, explanation is
here.
Top view of the connector on the circuit board - Pin 1 = red wire
REMINDER: once you program it, the program will not start running (!). You have to unplug the /RESET wire (connecting the Tiny10 to the AVR programmer)
and you have to unplug the AVR ISP mkII from the USB (!!) Why? Maybe the /RESET line stays forced low. I tried to add a pullup but to no avail. This stays a mystery so far but the article here under in the links mentions the same problem...

I welcome the newness, the fresh look of the King of Kitsch. Quentin Tarantino's new movie, Jackie Brown, is just that. Bt it's also alot more. It shows a director maturing. And a mature Quentin is a good thing indeed. Based on the book Rum Punch by Get Shorty author Elmore Leonard, Jackie Brown revives Pam Grier from a life of blaxplotation retirment, and Robert Forster, who turns in what may be the film's best performance (obviously, since it got him that Oscar nomination). Grier plays Jackie Brown, an airline stewardess and sometimes money runner for Ordell Robbie (Samuel L. Jackson, who ignites the screen as always). When ATF agent Ray Nicolet (Michael Keaton) and an LAPD officer pick Jackie up for running money, she begins to get a scheme. Robbie goes to get her bonded,and sees bail bondsman Max Cherry (Robert Forster). And soon after, Jackie is double-crossing all who try to stop her plan from working. Plus, Cherry begins to care for Jackie, and the expressions on Forster's face as he watches Jackie from afar or even talk to her is reminiscent of a lonely little boy in elemenatry school, eager for the popualr girl's attention. Also along for the ride in this Tarantino epic is Robert DeNiro, suprisingly subdued, as Louis Gara, Ordell's cronie from the days of yesteryear, and Bridget Fonda as Melanie, Ordell's pot-smoking, sex-obsessed, tan beach bunny. One clever scene involves a conversation and a photo between DeNiro and Fonda. It is perfectly Tarantino. There are many other memorable moments, like a POV shoot from three different people. All in all, Quentin Tarantino's latest film is a winner, and makes one salivate for his next project. (and the play he's in now, Wait Until Dark) What else would you expect from the Master of Witty Dialogue? One of the best films of 1997, and definitely one of the very slim films of recent years that makes you wish that the film would never end.

DJFacet can be customised by setting a number of predefined variables in your settings.py file.
Note
If you do not set this variables explicitly, they’ll get a default value as specified below (which in most situations will work just fine).
Defaults to 'facetspecs'.
It determines what file name the configuration file has, and where it is located.
By default, DJFacet expects to find the configuration file (djfacetspecs.py) at the root of your django project, that is, where your setting.py file is. In general, you shouldn’t need to change this setting.
Defaults to False.
It determines whether the logs DJFacet produces should be printed out in the shell. To be used only in development mode.
Defaults to True.
It determines whether the count for the zoom-points in the facets must be calculated, or not.
If your application has a lot of data (and facets), setting this value to False can be useful for testing, since it will speed up considerably the refresh operation.
Defaults to False.
It determines whether the Cache is used or not.
Once the cache is activated, DJFacet will always attempt to refresh the facets using the values stored in the database, instead of calculating them each time. Note that if the system detects unsaved objects, it caches them on-the-fly. Alternatively, you can cache all facets-contents using the appropriate management command (see the Management commands section).
Warning
If this parameter is set to True, you must have created the cached Faceted-Manager object using the appropriate management command (see the Management commands section).
Defaults to False.
It determines whether the user interface should update the facets values asynchronously, or not.
If set to True, each of the facets in your search interface will become an html <div> element that can be opened or close. When opened, the back-end is called and its contents are refreshed via ajax.
Defaults to 50.
It determines the max number of results that a faceted search should display. The rest of the results will be paginated accordingly (see the The Template system section for more details).
Defaults to False.
It determines whether the two-columns html template should be used for rendering the list of terms within a facet (see the The Template system section for more details).

USSR Howto
This section of the manual is a basic introduction to programming with
the USSR simulator framework. Consult the Javadoc documentation
for details of the API.
Adding a new robot step 1: describing the appearance
To add a new robot type, create an appropriate package to contain the robot
description. As an example of a minimal robot,
consider ussr.samples.stickybot. The
robot description is based on components from the
package ussr.description.robot with the
appearance described using elements from the
package ussr.description.geometry.
Concretely, the physics-engine-independent configuration of a robot is done
using the classes in ussr.description: the building blocks are
interpreted by a module factory to create physically simulated modules. If the
user of the robot does not need to be able to do any actuation or connector
alignment, the robot can be created directly from the description, using the
default
factory (which as an argument takes the type name of the robot). This
should be sufficient for creating an interactive representation of the robot
that can actuate its connectors. For more advanced features, a factory
must be defined, see below.
Adding a new robot step 2: defining the details
Details about a robot must be defined using a JME factory that can add to or
modify the representation of the robot. The default JME factories are provided
in the
package ussr.physics.jme.robots, a
fairly small example with an externally provided factory is
the White robot.
The module factory
uses components defined in the
package ussr.physics.jme and its subpackages to build a module.
