process#
The process
object is a global object and can be accessed from anywhere.
It is an instance of EventEmitter.
Event: 'exit'#
Emitted when the process is about to exit. This is a good hook to perform constant time checks of the module's state (like for unit tests). The main event loop will no longer be run after the 'exit' callback finishes, so timers may not be scheduled.
Example of listening for exit
:
process.on('exit', function() {
setTimeout(function() {
console.log('This will not run');
}, 0);
console.log('About to exit.');
});
Event: 'uncaughtException'#
Emitted when an exception bubbles all the way back to the event loop. If a listener is added for this exception, the default action (which is to print a stack trace and exit) will not occur.
Example of listening for uncaughtException
:
process.on('uncaughtException', function(err) {
console.log('Caught exception: ' + err);
});
setTimeout(function() {
console.log('This will still run.');
}, 500);
// Intentionally cause an exception, but don't catch it.
nonexistentFunc();
console.log('This will not run.');
Note that uncaughtException
is a very crude mechanism for exception
handling and may be removed in the future.
Don't use it, use domains instead. If you do use it, restart your application after every unhandled exception!
Do not use it as the node.js equivalent of On Error Resume Next
. An
unhandled exception means your application - and by extension node.js itself -
is in an undefined state. Blindly resuming means anything could happen.
Think of resuming as pulling the power cord when you are upgrading your system. Nine out of ten times nothing happens - but the 10th time, your system is bust.
You have been warned.
Signal Events#
Emitted when the processes receives a signal. See sigaction(2) for a list of standard POSIX signal names such as SIGINT, SIGUSR1, etc.
Example of listening for SIGINT
:
// Start reading from stdin so we don't exit.
process.stdin.resume();
process.on('SIGINT', function() {
console.log('Got SIGINT. Press Control-D to exit.');
});
An easy way to send the SIGINT
signal is with Control-C
in most terminal
programs.
process.stdout#
A Writable Stream
to stdout
.
Example: the definition of console.log
console.log = function(d) {
process.stdout.write(d + '\n');
};
process.stderr
and process.stdout
are unlike other streams in Node in
that writes to them are usually blocking. They are blocking in the case
that they refer to regular files or TTY file descriptors. In the case they
refer to pipes, they are non-blocking like other streams.
To check if Node is being run in a TTY context, read the isTTY
property
on process.stderr
, process.stdout
, or process.stdin
:
$ node -p "Boolean(process.stdin.isTTY)"
true
$ echo "foo" | node -p "Boolean(process.stdin.isTTY)"
false
$ node -p "Boolean(process.stdout.isTTY)"
true
$ node -p "Boolean(process.stdout.isTTY)" | cat
false
See the tty docs for more information.
process.stderr#
A writable stream to stderr.
process.stderr
and process.stdout
are unlike other streams in Node in
that writes to them are usually blocking. They are blocking in the case
that they refer to regular files or TTY file descriptors. In the case they
refer to pipes, they are non-blocking like other streams.
process.stdin#
A Readable Stream
for stdin. The stdin stream is paused by default, so one
must call process.stdin.resume()
to read from it.
Example of opening standard input and listening for both events:
process.stdin.resume();
process.stdin.setEncoding('utf8');
process.stdin.on('data', function(chunk) {
process.stdout.write('data: ' + chunk);
});
process.stdin.on('end', function() {
process.stdout.write('end');
});
process.argv#
An array containing the command line arguments. The first element will be 'node', the second element will be the name of the JavaScript file. The next elements will be any additional command line arguments.
// print process.argv
process.argv.forEach(function(val, index, array) {
console.log(index + ': ' + val);
});
This will generate:
$ node process-2.js one two=three four
0: node
1: /Users/mjr/work/node/process-2.js
2: one
3: two=three
4: four
process.execPath#
This is the absolute pathname of the executable that started the process.
Example:
/usr/local/bin/node
process.abort()#
This causes node to emit an abort. This will cause node to exit and generate a core file.
process.chdir(directory)#
Changes the current working directory of the process or throws an exception if that fails.
console.log('Starting directory: ' + process.cwd());
try {
process.chdir('/tmp');
console.log('New directory: ' + process.cwd());
}
catch (err) {
console.log('chdir: ' + err);
}
process.cwd()#
Returns the current working directory of the process.
console.log('Current directory: ' + process.cwd());
process.env#
An object containing the user environment. See environ(7).
process.exit([code])#
Ends the process with the specified code
. If omitted, exit uses the
'success' code 0
.
To exit with a 'failure' code:
process.exit(1);
The shell that executed node should see the exit code as 1.
process.getgid()#
Note: this function is only available on POSIX platforms (i.e. not Windows)
Gets the group identity of the process. (See getgid(2).) This is the numerical group id, not the group name.
if (process.getgid) {
console.log('Current gid: ' + process.getgid());
}
process.setgid(id)#
Note: this function is only available on POSIX platforms (i.e. not Windows)
Sets the group identity of the process. (See setgid(2).) This accepts either a numerical ID or a groupname string. If a groupname is specified, this method blocks while resolving it to a numerical ID.
if (process.getgid && process.setgid) {
console.log('Current gid: ' + process.getgid());
try {
process.setgid(501);
console.log('New gid: ' + process.getgid());
}
catch (err) {
console.log('Failed to set gid: ' + err);
}
}
process.getuid()#
Note: this function is only available on POSIX platforms (i.e. not Windows)
Gets the user identity of the process. (See getuid(2).) This is the numerical userid, not the username.
if (process.getuid) {
console.log('Current uid: ' + process.getuid());
}
process.setuid(id)#
Note: this function is only available on POSIX platforms (i.e. not Windows)
Sets the user identity of the process. (See setuid(2).) This accepts either a numerical ID or a username string. If a username is specified, this method blocks while resolving it to a numerical ID.
if (process.getuid && process.setuid) {
console.log('Current uid: ' + process.getuid());
try {
process.setuid(501);
console.log('New uid: ' + process.getuid());
}
catch (err) {
console.log('Failed to set uid: ' + err);
}
}
process.getgroups()#
Note: this function is only available on POSIX platforms (i.e. not Windows)
Returns an array with the supplementary group IDs. POSIX leaves it unspecified if the effective group ID is included but node.js ensures it always is.
process.setgroups(groups)#
Note: this function is only available on POSIX platforms (i.e. not Windows)
Sets the supplementary group IDs. This is a privileged operation, meaning you need to be root or have the CAP_SETGID capability.
The list can contain group IDs, group names or both.
process.initgroups(user, extra_group)#
Note: this function is only available on POSIX platforms (i.e. not Windows)
Reads /etc/group and initializes the group access list, using all groups of which the user is a member. This is a privileged operation, meaning you need to be root or have the CAP_SETGID capability.
user
is a user name or user ID. extra_group
is a group name or group ID.
Some care needs to be taken when dropping privileges. Example:
console.log(process.getgroups()); // [ 0 ]
process.initgroups('bnoordhuis', 1000); // switch user
console.log(process.getgroups()); // [ 27, 30, 46, 1000, 0 ]
process.setgid(1000); // drop root gid
console.log(process.getgroups()); // [ 27, 30, 46, 1000 ]
process.version#
A compiled-in property that exposes NODE_VERSION
.
console.log('Version: ' + process.version);
process.versions#
A property exposing version strings of node and its dependencies.
console.log(process.versions);
Will print something like:
{ http_parser: '1.0',
node: '0.10.4',
v8: '<IP_ADDRESS>',
ares: '1.9.0-DEV',
uv: '0.10.3',
zlib: '1.2.3',
modules: '11',
openssl: '1.0.1e' }
process.config#
An Object containing the JavaScript representation of the configure options
that were used to compile the current node executable. This is the same as
the "config.gypi" file that was produced when running the ./configure
script.
An example of the possible output looks like:
{ target_defaults:
{ cflags: [],
default_configuration: 'Release',
defines: [],
include_dirs: [],
libraries: [] },
variables:
{ host_arch: 'x64',
node_install_npm: 'true',
node_prefix: '',
node_shared_cares: 'false',
node_shared_http_parser: 'false',
node_shared_libuv: 'false',
node_shared_v8: 'false',
node_shared_zlib: 'false',
node_use_dtrace: 'false',
node_use_openssl: 'true',
node_shared_openssl: 'false',
strict_aliasing: 'true',
target_arch: 'x64',
v8_use_snapshot: 'true' } }
process.kill(pid, [signal])#
Send a signal to a process. pid
is the process id and signal
is the
string describing the signal to send. Signal names are strings like
'SIGINT' or 'SIGUSR1'. If omitted, the signal will be 'SIGTERM'.
See kill(2) for more information.
Note that just because the name of this function is process.kill
, it is
really just a signal sender, like the kill
system call. The signal sent
may do something other than kill the target process.
Example of sending a signal to yourself:
process.on('SIGHUP', function() {
console.log('Got SIGHUP signal.');
});
setTimeout(function() {
console.log('Exiting.');
process.exit(0);
}, 100);
process.kill(process.pid, 'SIGHUP');
process.pid#
The PID of the process.
console.log('This process is pid ' + process.pid);
process.title#
Getter/setter to set what is displayed in 'ps'.
When used as a setter, the maximum length is platform-specific and probably short.
On Linux and OS X, it's limited to the size of the binary name plus the length of the command line arguments because it overwrites the argv memory.
v0.8 allowed for longer process title strings by also overwriting the environ memory but that was potentially insecure/confusing in some (rather obscure) cases.
process.arch#
What processor architecture you're running on: 'arm'
, 'ia32'
, or 'x64'
.
console.log('This processor architecture is ' + process.arch);
process.platform#
What platform you're running on:
'darwin'
, 'freebsd'
, 'linux'
, 'sunos'
or 'win32'
console.log('This platform is ' + process.platform);
process.memoryUsage()#
Returns an object describing the memory usage of the Node process measured in bytes.
var util = require('util');
console.log(util.inspect(process.memoryUsage()));
This will generate:
{ rss: 4935680,
heapTotal: 1826816,
heapUsed: 650472 }
heapTotal
and heapUsed
refer to V8's memory usage.
process.nextTick(callback)#
On the next loop around the event loop call this callback.
This is not a simple alias to setTimeout(fn, 0)
, it's much more
efficient. It typically runs before any other I/O events fire, but there
are some exceptions. See process.maxTickDepth
below.
process.nextTick(function() {
console.log('nextTick callback');
});
This is important in developing APIs where you want to give the user the chance to assign event handlers after an object has been constructed, but before any I/O has occurred.
function MyThing(options) {
this.setupOptions(options);
process.nextTick(function() {
this.startDoingStuff();
}.bind(this));
}
var thing = new MyThing();
thing.getReadyForStuff();
// thing.startDoingStuff() gets called now, not before.
It is very important for APIs to be either 100% synchronous or 100% asynchronous. Consider this example:
// WARNING! DO NOT USE! BAD UNSAFE HAZARD!
function maybeSync(arg, cb) {
if (arg) {
cb();
return;
}
fs.stat('file', cb);
}
This API is hazardous. If you do this:
maybeSync(true, function() {
foo();
});
bar();
then it's not clear whether foo()
or bar()
will be called first.
This approach is much better:
function definitelyAsync(arg, cb) {
if (arg) {
process.nextTick(cb);
return;
}
fs.stat('file', cb);
}
process.maxTickDepth#
- Number Default = 1000
Callbacks passed to process.nextTick
will usually be called at the
end of the current flow of execution, and are thus approximately as fast
as calling a function synchronously. Left unchecked, this would starve
the event loop, preventing any I/O from occurring.
Consider this code:
process.nextTick(function foo() {
process.nextTick(foo);
});
In order to avoid the situation where Node is blocked by an infinite loop of recursive series of nextTick calls, it defers to allow some I/O to be done every so often.
The process.maxTickDepth
value is the maximum depth of
nextTick-calling nextTick-callbacks that will be evaluated before
allowing other forms of I/O to occur.
process.umask([mask])#
Sets or reads the process's file mode creation mask. Child processes inherit
the mask from the parent process. Returns the old mask if mask
argument is
given, otherwise returns the current mask.
var oldmask, newmask = 0644;
oldmask = process.umask(newmask);
console.log('Changed umask from: ' + oldmask.toString(8) +
' to ' + newmask.toString(8));
process.uptime()#
Number of seconds Node has been running.
process.hrtime()#
Returns the current high-resolution real time in a [seconds, nanoseconds]
tuple Array. It is relative to an arbitrary time in the past. It is not
related to the time of day and therefore not subject to clock drift. The
primary use is for measuring performance between intervals.
You may pass in the result of a previous call to process.hrtime()
to get
a diff reading, useful for benchmarks and measuring intervals:
var time = process.hrtime();
// [ 1800216, 25 ]
setTimeout(function() {
var diff = process.hrtime(time);
// [ 1, 552 ]
console.log('benchmark took %d nanoseconds', diff[0] * 1e9 + diff[1]);
// benchmark took<PHONE_NUMBER> nanoseconds
}, 1000);

The last statement in a method is automatically returned, the use of the return
keyword is redundant in this case.

Humans have been playing board games for at least hundreds of years. They’ve evolved into the ultra-strategic card games and luxurious high-quality boards we find today on the shelves of our nearest retail stores. But do you ever think about where these games came from? Likely one of the most ancient board games still played today is tic tac toe. This is probably because it’s so simple that you don’t even need a board to play! But even with all its simplicity, the history of tic tac toe is more rich and surprising than you’d think.
Where Did the Name Come From?
The early Roman version was known as terni lapilli, or three pebbles at a time. In the mid-1800s, Britain used the name noughts and crosses, with nought referring to the O’s (or zeros) used in the game. The phrase tick-tack-toe wasn’t used until the late 1800s, and there’s some findings that report it might have been used to describe a completely different game.
The United States officially adopted the name tic tac toe in the 20th century. Historians aren’t completely clear about the origin of the game’s name, but it could be referring to the noise of repetitive ticking or writing that goes along with the game’s play.
Tic Tac Toe Variations
Because of its simplistic format and potential for a game of almost any size, there are many possibilities for tic tac toe variations. A common one is Connect 4, where a player must create four in a row of their team’s color on an interactive grid board using chips.
Other popular examples of tic tac toe variations include Mojo, Toss Across, Nine Men’s Morris, Quarto, and Gobblet, among many others.
It’s also possible to expand the board of tic tac toe and play in three dimensions. This can be done by using 3x3x3 tic-tac-toe boards, making a uniquely difficult challenge if more than two people are playing.
THE EVOLUTION OF BOARD GAME STANDARDS
Instead of using them as a way to pass the time, we utilize board games as a means of entertainment and to foster togetherness with family and friends. Board games for adults are becoming more and more popular, as are high-end luxury game boards and setups to build and strengthen those relationships.
If you’re looking for your next board game that’ll impress even the most skilled enthusiasts, Aurosi is the site that has it all.

Bill on extension of SC, ST quota in LS, Assemblies introduced
It also proposes scrapping of nomination of Anglo-Indians
by Special CorrespondentA Bill seeking to extend by 10 years reservation to the Scheduled Castes and Scheduled Tribes in the Lok Sabha and the Assemblies and remove the provision of nominating two members of the Anglo-Indian community to the Lok Sabha was introduced in the House on Monday.
The reservation given to SCs, STs and the Anglo-Indian community for the past 70 years is to end on January 25, 2020.
Trinamool opposes
Trinamool Congress MP Saugata Roy opposed the introduction of the Constitution (126th) Amendment Bill, saying the Anglo-Indian community was being deprived of representation.
Law Minister Ravi Shankar Prasad said that while the merits of the Bill could be gone into during the debate, the extension of reservation to the SC and ST communities was for representation, while the Anglo-Indian community was nominated.
“According to the 2011 census, there are 296 members of the Anglo Indian community in the entire country. However, I would still maintain that we have not closed our minds to revisiting the issue,” he said.
The Bill was then cleared for introduction by voice vote to be taken up for consideration and passing later.

Home Library Service reading groups
Monthly reading groups aimed at older people, including users of the At Home Library Service and their carers, families or volunteer visitors, offering a stimulating programme of topics to discuss and read around. If you require use of the free transport then contact the library at least one week before the event. At Home Library Service Reading Groups are held at the following Suffolk libraries:

RPANBot only stores information when it is needed to provide one of its features.
When is data removed or how can I remove it?You can delete your stream notifications settings using a command and set the custom prefix back to the bot's default prefix.
When the bot leaves or is removed from a guild it will attempt to delete any settings it has stored for that guild.
Alternatively, you can contact the developers using the bot's feedback command, or sending a modmail message to r/RPANBot through Reddit, requesting that any settings for your guild be deleted.
What information does RPANBot store?This policy may need to change with the integration of new features into RPANBot.

I have used Salvia Divinorum a total of 4 times now. I considered posting an experience report earlier, but opted not to, since my experiences had not been anything interesting or useful. All experiences were with smoking dried leaves. This was not an extract. I hope this report gives new users a slight idea of what can be expected.
--
Experience #1:
Sitting in my room, I had just received my salvia. I rolled a small amount into a cig, and proceeded to light up. I held in every hit I took. Felt slightly stoned, my visual perception was changed. Going to bed, I felt slightly cold.
--
Experience #2:
The next day, I packed a small bowl, got 2 hits, and held them for as long as possible. Had the same stoned feeling, and laid back down in bed, going to sleep. Had an incredibly vivid dream, that I thought was real, even a few hours after I'd awakened. In the dream, I was in bed (the same position that I was actually laying) and someone came in the door, took a look around, and left. Upon waking up, I thought nothing of it, until I realized that my door had been, and was still locked. I woke up quite refreshed, and felt great.
--
Experience #3:
Yesterday. It had been about 3 weeks since I'd received the Salvia. I packed a bowl and took 3 hits. I felt the effects come on strong. I felt something I hadn't before, a pressure pushing against my back and arms, accompanied by a slight tingling sensation. I proceeded inside and no longer felt the pressure or tingling, the the same stoned feeling I'd had previously.
--
Experience #4:
Today. I had a nice relaxing chair ready next to me. I took the first hit, held as long as I could. Started to take the second hit, feeling the effects start to take ahold. Third hit, I could feel pressure pushing along the back of my body, as well as a slight tingling. I was out of breath when I took the third hit, and didn't hold it in, but quickly took another 4th/final hit. I sat down in the chair with my head back, and closed my eyes, releasing the final hit.
I felt as if the sober 'reality' I had been experiencing just minutes before was washing away to display the 'true reality' of the universe. I was no longer sitting at home, I was in the land of the 'Neatz'. I did not physically see these people, only through my mind's eye. It wasn't a visual hallucination, it was an image in my head. These people were short, but also proportionally small, possesing almost cartoonish looking features (almost like the munchkins in Wizard of Oz).
These 'Neatz' controlled everything that happens in our universe, and lived inside every object. I knew they were watching me, and started feeling pressure at different points on my body. As I felt this, it passed over my neck, and started laughing because it tickled. I temporarily opened my eyes, and perceived my actual surroundings. I was right here at home, but I perceived it as being just a room, somewhere in this mystical realm.
I re-closed my eyes, and could again perceive these odd creatures (although I knew they weren't normal humans, they were on the same intelligence level if not smarter than myself). For a second, although I did not realize I had just smoked Salvia, I knew that this reality was induced. I made a comment out loud about how someone should do a pushup (which was somehow going to make things clearer). I opened my eyes, and was still a little disoriented, but I stood up and walked into my room. Reality has returned, but I still feel slightly buzzed. I turned on the tv, but the sound seemed unpleasant, so I muted it, because I didn't like it being off. I'm gonna take a shower, then I'm gonna finish writing this.
Ok, I'm not feeling the Salvia at all anymore. In the shower, I thought of a few more things to mention. Although I haven't seen the show since I was a child, the 'Neatz' remind me of some of the creatures from Fraggle Rock. When I took the first hit, it was about 11:38, and when I sat down in my room, it was 11:46. This means the strong part of the experience lasted about 8 minutes.
Near the end of that 8 minutes, I remember wanting it to end, but was reminded that in a few minutes, I'd feel better. I apologize if things don't flow logically, or if it seems like there are gaps, It was an extremely new experience, and even though it was vivid, it's hard to describe. I've gained a whole lot more respect for the plant after today's experience, and with a strong experience like this, I fully agree with everyone that says this is not a social drug.
Experience Reports are the writings and opinions of the individual authors who submit them.
Some of the activities described are dangerous and/or illegal and none are recommended by Erowid.

SparseCategoricalCrossentropy
Computes the crossentropy metric between the labels and predictions.
tf.compat.v1.keras.metrics.SparseCategoricalCrossentropy
tf.compat.v2.keras.metrics.SparseCategoricalCrossentropy
tf.compat.v2.metrics.SparseCategoricalCrossentropy
tf.metrics.SparseCategoricalCrossentropy
Use this crossentropy metric when there are two or more label classes.
We expect labels to be provided as integers. If you want to provide labels
using one-hot
representation, please use CategoricalCrossentropy
metric.
There should be # classes
floating point values per feature for y_pred
and a single floating point value per feature for y_true
.
In the snippet below, there is a single floating point value per example for
y_true
and # classes
floating pointing values per example for y_pred
.
The shape of y_true
is [batch_size]
and the shape of y_pred
is
[batch_size, num_classes]
.
m = tf.keras.metrics.SparseCategoricalCrossentropy() m.update_state( [1, 2], [[0.05, 0.95, 0], [0.1, 0.8, 0.1]]) # y_true = one_hot(y_true) = [[0, 1, 0], [0, 0, 1]] # logits = log(y_pred) # softmax = exp(logits) / sum(exp(logits), axis=-1) # softmax = [[0.05, 0.95, EPSILON], [0.1, 0.8, 0.1]] # xent = -sum(y * log(softmax), 1) # log(softmax) = [[-2.9957, -0.0513, -16.1181], [-2.3026, -0.2231, -2.3026]] # y_true * log(softmax) = [[0, -0.0513, 0], [0, 0, -2.3026]] # xent = [0.0513, 2.3026] # Reduced xent = (0.0513 + 2.3026) / 2 print('Final result: ', m.result().numpy()) # Final result: 1.176

name
: (Optional) string name of the metric instance.dtype
: (Optional) data type of the metric result.from_logits
: (Optional ) Whether y_pred
is expected to be a logits tensor.
By default, we assume that y_pred
encodes a probability distribution.axis
: (Optional) Defaults to -1. The dimension along which the metric is
computed.__init__
__init__( name='sparse_categorical_crossentropy', dtype=None, from_logits=False, axis=-1 )
Creates a MeanMetricWrapper
instance.

fn(y_true, y_pred, **kwargs)
.name
: (Optional) string name of the metric instance.dtype
: (Optional) data type of the metric result.**kwargs
: The keyword arguments that are passed on to fn
.__new__
__new__( cls, *args, **kwargs )
Create and return a new object. See help(type) for accurate signature.
reset_states
reset_states()
Resets all of the metric state variables.
This function is called between epochs/steps, when a metric is evaluated during training.
result
result()
Computes and returns the metric value tensor.
Result computation is an idempotent operation that simply calculates the metric value using the state variables.
update_state
update_state( y_true, y_pred, sample_weight=None )
Accumulates metric statistics.
y_true
and y_pred
should have the same shape.
y_true
: The ground truth values.y_pred
: The predicted values.sample_weight
: Optional weighting of each example. Defaults to 1. Can be
a Tensor
whose rank is either 0, or the same rank as y_true
,
and must be broadcastable to y_true
.Update op.

Players started modding Halo Reach within an hour of the first test flight
by Ian BoudreauThere are still a few weeks to go before Halo Reach arrives on PC, but players have already started modding the game. 343 Industries community lead Brian Jarrard said that within an hour of the first Halo Reach test flight going live, players were changing how the game worked.
“The speed at which people have started to mod and tinker already has been really cool,” Jarrard told us at XO19. “It took them maybe an hour from the first flight to start changing weapon behaviours, making players that could jump and fly.”
Jarrard said he even saw one instance of a player-created nightmare contraption like something out of Mad Max.
“I saw somebody who had just mashed a bunch of vehicles together and created this new abomination that had all the weapons attached to it,” he said. “We knew that was going to happen, I just don’t think we knew it would happen within an hour of the flight going up.”
The team at 343 Industries says they welcome modders and have been looking forward to this aspect of launching Reach on PC.
“One of the coolest parts about PC is it’s an open-ended platform,” Jarrard said. “My perfect world is, you put these games out in a great baseline experience that’s true to the originals, and then the community takes the keys at that point and they make it their own.”
There are a few provisos, of course: as a competitive multiplayer game, Halo Reach will need some limitations in place to make sure the online experience stays free of mods.
“In matchmaking, we’re not going to allow custom content, just to sort of protect the integrity of the core experience,” Jarrard said. “Outside of that? We want fans to tinker, create their own experiences, play custom games.”
“Who knows what Reach on PC will look like years from now?” he said. “I’m excited.”
Halo Reach will arrive on PC December 3. It’s the first part of The Master Chief Collection.

Since I bought my WiFi-router in 2006, a Linksys WRT54G, I've been interested in open source router firmwares and network hacking. At the time, the features seemed quite amazing. You could do all kinds of super features, for instance QoS, formerly only available in professional equipment.
The firmware that stuck with me is OpenWRT but there is more to choose from, for instance Tomato and DD-WRT.
Quite recently I've started poking around with embedded, using node.js on a Raspberry Pi. When I needed WiFi that was not always easy:
You might not be surprised that I started looking back to my dear OpenWRT. And since I last used it, lots of cheap hardware has come out which makes it ideal for low budget embedded hacking.
The TP-Link MR-3020 is about $30 / €20 and has a nice hardware despite its small size:
Watch out for TP-Link's over-promising marketing lingo though: "Portable 3G/4G Wireless N Router" does not mean a SIM card reader and 3G chip on the board. It simply means that they added software support for some 3G USB dongles. When you run OpenWRT you still have the option to add a 3G USB dongle, just like with any other OpenWRT compatible hardware that has USB.
So, you ask, why should I buy something like this and what can I do with OpenWRT? Well, here are some of my ideas:
There are obviously many cool hacks for the OpenWRT out there, for instance:
So check it out and get started hacking! As a frontend developer I admit that the learning curve can sometimes seem steep, but getting started is very easy and you can get help in the OpenWRT forums. The reward for learning about network hacking is two-fold; First of all it's fun to add network support to your hobby projects. Secondly, you get to know more about network stuff. Having insight in the "plumbing" of the Internet is something you will have lots of use for even as a frontend developer. For one thing, it can have a huge affect on page load speeds.


| DOSE: |
15 mg |
oral |
2C-B |
(pill / tablet) |
[Erowid Note: The author believed the dosage to be 75mg, but from their reaction and the fact that the main 2C-B pills were 5mg each, we have assumed their dosage was 15mg.]
I have experienced 2cb numerous times when living in Belgium, and fondly think of it as the best drug I have ever had the privilege of doing. I have been clean for 3 years now but I still fondly remember my first 2cb experience and would like to share it with you and also give you my opinion on this marvelous drug.
It was probably about 1994, might have been a year or two before...can't quite remember anymore, but a few friends and I decided to try 2cb from the local 'Smart Shop'. We had never heard of it before and based on the other products they had there it seemed like the most interesting one. We each bought three 25mg pills. We stepped out and a few blocks later each popped all three pills. There was no taste on my tongue, just felt as if I had some random pill on there. I drank it down with some water and then we all went into the main part of Antwerp. One of my friends had for some reason forgotten to tell us that he had an appointment to get his hair cut so we all went there and hung out while he got his trim.
Once there I had a clock in front of me so I pretty much was counting down to when it would start affecting me, and after about 40 - 45 minutes from taking the pills I felt a slight weightlessness feeling, but more in the sense of a huge burden was just taken from my shoulders and I could now walk carefree. I went and asked my friends and they all started feeling this same feeling around that time... Once we were on our way again it started to kick in more and more, giving us fun visuals as we walked around the city...everything was more defined than it should be. By the docks in Antwerp there is a walking area raised up, hard for me to describe, but anyhow, the ground isn't smooth, it's very bumpy. While walking on there the shadow of these bumps looked like hills, the definition was insane and walking on it became difficult, so we all sat down. Throughout the experience we kept repeating this...we would walk for 10 minutes then sit for 10 minutes, and so on.
At various points during the experience one person would have a need to go on their own, but this would only last for a few minutes, they would step out of the group and walk their own way, hen we would all run into each other and re-greet each other as if we hadn't seen each other in years...it seems that the most stories come out of the side quest ;) My sidequest brought me to the big cathedral in Antwerp, and this all taking place in the summer time, towards nightfall when the sky is a slightly darker shade of blue, they had turned the lights on for the cathedral, basically the lights shine upwards to define it so you can have a nice view of it, but in this lighting and with 2cb the cathedral looked like a giant 3 d puzzle like the ones you have to build up....I could see the individual puzzle pieces, it was awesome...
My observations on 2cb:
Dosage varies from person to person, you don't need a high dosage for 2cb to work. I have NEVER had a bad trip on 2cb, and I have never heard about a bad trip on it (except for someone snorting it)...2cb seems to take away my problems at the beginning but towards the end when I am coming down it slowly reintroduces me to reality, letting me face it one step at a time...the come down was never hard and never long...it was a great way to come off of it making the whole experience more and more enjoyable...
FYI: At that point in time 2cb was a legal drug in Belgium, and was bought over the counter at a Smart Shop...I am not sure what the legality is there nowadays since I no longer live there, and I am aware that it is an illegal substance in the US. That said, I used this drug in legal circumstances, and therefore am not ashamed to answer questions regarding it, however please note I have been sober for a long time, and have no desire to do drugs anymore. I don't have anything against them though, but anyhow, that is the end of my rant.

OFF-LINE MINIMUM
Off-line minimum problem is a problem concerned with maintaining the dynamic set T with the help of operation such as INSERT and EXTRACT-MIN. In this a sequence is maintained with the n INSERT and the m EXTRACT-MIN operations.
Every key has been inserted only once. It is used for determining the key that has been returned by EXTRACT-MIN operation. This problem is termed as off-line as the entire sequence is to be processed before the determination of the returned keys.
The algorithm of OFF-LINE-MINIMUM (m, n) is given below:
OFF-LINE-MINIMUM (m, n)
//for loop to trace all elements
1. for
2. Determine the value of j such that
//Use of if condition to check whether value should be extracted or not
3. if
4.
5. let l be the smallest value greater than j
for which set Kl exists
//Add the element in the array and destroy from the previously stored location
6. , destroying Kj
7. return extracted
a. Consider the sequence given below:
As it is clear from the above sequence that the number of INSERT call (n) is 9 and number of EXTRACT-MIN call (m) is 6.
As there are 6 EXTRACT-MIN operations, the result that has been obtained when they are performed is given below:
• When first EXTRACT-MIN operation is performed, the array has elements 4 and 8 in it. So, this call will extract the element 4.
• When second EXTRACT-MIN operation is performed, the array has elements 8 and 3 in it. So, this call will extract the element 3.
• When third EXTRACT-MIN operation is performed, the array has elements 8, 9, 2 and 6 in it. So, this call will extract the element 2.
• When fourth EXTRACT-MIN operation is performed, the array has elements 8, 9 and 6 in it. So, this call will extract the element 6.
• When fifth EXTRACT-MIN operation is performed, the array has elements 8 and 9 in it. So, this call will extract the element 8.
• When sixth EXTRACT-MIN operation is performed, the array has elements 9, 1 and 7 in it. So, this call will extract the element 1.
This sequence will provide the extracted array as:
4 3 2 6 8 1
The table that has been formed after iterations i for given sequence is shown below:
In the table given above, no changes have been made when the value of i is 5 and 7. It is because the value of j becomes equal to m+1.
b. In order to prove that the array returned by OFF-LINE-MINIMUM is correct, its contradictory should be considered.
Consider that the extracted array returned by the OFF-LINE-MINIMUM is not correct.
Consider x=extracted [j] be the smallest value.
Suppose that for this value, the array is incorrect.
And taking the correct solution is the array answer.
Consider y=answer [j] which is not equal to value of x.
So, there are two possibilities;
Either.
If both the cases will false, this means that OFF-LINE-MINIMUM always returns correct extracted array.
Assume;
This means that either y has smallest value of incorrect extracted array or the appearance of y is not there in extracted array.
The processing of y is always done before processing x.
So y had set value of m+1.
But, if answer [j] was set to y, this means that y initially have been in some Ki with i <= j.
As there is no value of extracted [j], yet processing of y is there. This means that the value of y cannot be inserted in set, because there is only union with the set above and there is no union to yet.
Therefore, the condition is false.
Consider the case when:
The argument is that x must appear in the answer array. The appearance of x should be before the extraction of jth in the original sequence. It is because there is no backward movement of sets in OFF-LINE MINIMUM algorithm. Only the operation of unions is there with sets that are later than it.
If the extraction of x is not there by the jth extraction, this means that optimal solution will be x instead of y for the extraction of jth since i is smaller.
Therefore, the optimal solution must have extracted x for some.
But, that means that extracted [j] holds some.
By similar reasoning as above, x cannot be moved past the set since extracted [i] would have been empty at the time x was chosen.
Since, only union with the sets is there and has not been union yet, we cannot put the value of x in extracted [j] before extracted [i].
Therefore, the condition is false.
This is a contradiction since it was assumed that x is not equal to y and it is proved that, and cannot be true, x has to be equal to y and extracted array is correct.
c. The OFF-LINE-MINIMUM can be implemented with the help of a disjoint set data structure.
Initially n sets are created with the help of MAKE-SET operation. After that the union operation for n–m times are performed for the creation of sets.
For each set, maintain these three additional pieces of information which mention below:
• One to the state next to it,
• Second to the previous set
• Third the number itself.
Number will correspond to j, the next will correspond to and the previous will correspond to. These properties can be easily maintained after union of two sets.
The ‘for’ loops of OFF-LINE-MINIMUM algorithm, has iterations which first call FIND-SET on i . The number field is used on returned representative as j.
Then, to determine the next smallest set greater than j, simply use the next pointer.
At-most m UNION calls are made and the same method as above is followed.
A total of n MAKE-SET operations, n FIND-SET and n UNION operations are there. Total 3n operations which can be solved in amortized time. After making the changes, the algorithm of OFF-LINE-MINIMUM (m, n) is given below:
OFF-LINE-MINIMUM (m, n)
//for loop to trace all elements
1. for
2.
//Use of if condition to check whether value should be extracted or not
3. if
4.
5.
//link the value of j and l and remove Kj from linked list
6. and removal of Kj from linked list
7. return extracted
Hence complexity of the worst case for the above implementation is equal to .
DEPTH DETERMINATION
In depth determination, a forest of trees is maintained and the following three main operations are used:
MAKE-TREE(t) : This operation is used to create a tree which has a single node t.
FIND-DEPTH(t) : This operation is used to find the depth of the node in a tree.
GRAFT (p, t) : This operation is used to make the node p the child of node t. Here, p is the root and node t may or may not be the root.
Consider the total number of nodes as n and n = m/3.
• Apply n MAKE-TREE operations on n single nodes (that is, make n trees each with a single node).
• Apply n–1 GRAFT operations on these n trees to form a single tree.
• Apply FIND-DEPTH(vi) operations on the resulting tree. In other words, find depth of each node in the tree.
• Each MAKE-TREE operation takes time. Thus, n MAKE-TREE operation takes time.
• Each GRAFT operation takes time. Thus, n GRAFT operation takes time.
• Each FIND-DEPTH operation takes time.
The total time required for the sequence of m operations is as follows:
Hence the total time required to apply m operations is ?( m 2 ).
MAKE-TREE is used to create a new tree with a single node and having its pseudo time set to 0.
A disjoint set data structure is defined as a collection of disjoint dynamic sets. Each of these can be identified by members of the set, which are representative.
In the dynamic set implementations, each element of the set is represented by an object and performs some operations.
1. Make-Set (v): Make-set is used to create a new set, which contains a single member (also representative). Since the sets are disjoint, v should not be in any other set.
2. Union (u, v): It combines the two sets u and v into one new set.
3. Find-Set (v): This operation is used to return a pointer to representative of a set that contains v.
The operation MAKE-TREE is similar to MAKE-SET operation. MAKE-TREE has one property that sets the d value to 0. The implementation of MAKE-TREE by using Make-Set operation is as follows:
MAKE-TREE (v)
//set the value of v as v.p
//set the rank of v as 0
//set the value of v.p as 0
In the case of disjoint-sets, every single node has a depth of 0 and find path for node v consists of d [ v ]. Hence, the value of d [ v ] is always set to 0.
The operation FIND-DEPTH is implemented by modifying the operation FIND-SET. FIND-SET operation uses path compression, which makes every node point to the root. FIND-SET recursively calls itself and finds the path from v to r (root).
The FIND-SET can be modified to implement FIND-DEPTH, so that in each iteration, pseudo distance of node vi is updated.
FIND-SET (v)
//Condition to check whether the value of node is equal to its parent
if
//Assign the value of node to integer y
//recursion starts here, FIND-SET is used to get the value of representative
// element
//update the pseudo distance
//return the value of v.p
return v.p
The above operation uses path compression and it updates the pseudo distances for each node.
The newly implemented FIND-DEPTH operation using modified FIND-SET operation is as follows:
FIND-DEPTH(v)
//Call FIND-SET
FIND-SET(v)
return
The FIND-DEPTH algorithm calls the algorithm of FIND-SET in order to perform path compression and to update the pseudo-distances. Finally, FIND-DEPTH returns the updated pseudo distance of v.
The operation is similar to the operation UNION BY RANK. The implementation of to combine r and v, using the modified UNION and LINK procedures, is as follows:
GRAFT(r, v)
//Call FIND-SET function to know representative element of r
//Call FIND-SET function to know representative element of v
//Call FIND-DEPTH function and assign the value of depth to variable z
//if condition to compare rank for performing LINK operation
if
//After knowing that the rank of r’ is bigger, make it as root of smaller tree (v’)
//the depth of r’ should be increased 1 more than depth of v
//Update value of v’
//When if condition is not satisfied, make v’ as root of smaller tree (r’)
else
//Update the value of r’
//if condition to check whether rank of both trees is same or not
if
//When the rank of both trees is same, the procedure has been followed as given // above, this leads to make increment in rank of v’
The algorithm finds out the representative elements of r and v, and then calculates the depth of v by using FIND-DEPTH function. Afterwards, the algorithm compares the ranks of v’ and r’ in order to perform LINK operation.
LINK creates the new tree. The tree with smaller rank becomes the child of tree having larger rank. Then LINK updates the depths of r’ and v’.
Consider the algorithm defined in the part (b). The operation MAKE-TREE is similar to operation MAKE-SET, FIND-DEPTH operation is similar to FIND-SET and GRAFT operation is similar to UNION operation.
With the reference of theorem 21.14 in the textbook, the worst-case time complexity is equal to.
Least-Common-Ancestor (LCA)
Least common ancestor algorithm is used to find the ancestor of two nodes that is farthest from the node.
Consider the tree given below:
Suppose the query is to find the LCA of nodes 4 and 7. This algorithm initially considers all the nodes as white, after visiting all children of node, the node is colored black. This algorithm returns a node that has both nodes as its child is taken and it should be farthest node from the node. In order to find LCA of pair {4, 7}, all the ancestors of both nodes are visited and it is found that the LCA of the pair is node 6.
a. As considering the algorithm, the least common ancestor is calculated in such a way that the shared ancestor is farthest and has maximum value of depth from the root.
The procedure has a part which is used for determining the distance between node pairs in a tree, the print statement is used to find the least common ancestor with the help of the FIND-SET (v) operation. This takes place in the last step. This means farthest from the root.
So, it is called exactly once in the procedure. This means when the algorithm is at the stage of termination.
b. By using the disjoint-set operation computation of the sequences is there.
Consider and for the nodes u and v.
In both sequences, P is used to represent the parent of given node and r is used to represents the root node of the tree.
The first element that has been obtained for the two sequences is the LCA.
Hence the time complexity always equal to the depth of tree.
It can be represented as (where h is the height of tree).
c. Proof:
Suppose we know the least common ancestor of nodes u and v in a rooted tree T. The tree also has a node is the node w whose height is least and is an ancestor of u and v.
It has been given a rooted tree T and a set P having a pairs of node in T for the off-line least common ancestor’s problem, and here the least common ancestor of pair formed in T is determined.
In order to prove that Least Common Ancestor always prints the LCA of pairs u and v for each pair {u, v}?P
Consider the Depth-First Search Algorithm:
1. Recall that in DFS all nodes start white, open nodes are colored grey and closed nodes are colored black. Grey nodes reside in a stack S.
2. For each pink node w maintain a set D w consisting of w and all black nodes whose least pink ancestor is w.
3. When a node u is finished, for all pairs (u, v) ?P such that v is black and v ?D w for some grey node w, w is the least common ancestor of u and v.
Initial call is to LCA (root [T]):
LCA (u)
// creation of new set in which u is the only element
1. MAKE-SET (u)
// color operation
2. Color [u] ? grey # ancestor [u] ? u.
 UNION (u, v) – union
// representative of u’s set has pointer to u.
6. ancestor.[FIND (u)] ? u
//change the color of node u to black
7. color (u) ? black
//for loop to know all the pairs of u and v
8. for each node v such that {u,v} ?P
//if condition to check whether all the children of node v are visited or not
9. if color [v] = BLACK
//This statement will return the LCA of two nodes
10. then print ‘the LCA of’ u ‘and’ v ‘is’ ancestor[FIND(v)
// terminate
Therefore, it is proved that LCA correctly prints the least common ancestor of u and v for each pair {u, v} ? P.
d. An optimal disjoint-set data structure can be obtained by performing two heuristics- path compression and union by rank. If LCA algorithm is implemented with the help of the disjoint-set data structure then it will use disjoint-set of operations.
In the same tree, the multiple pairs of nodes are calculated. After implementation, it is made to run in (where as the size of the input).
It is much slower than the linear time which has the complexity as.
