NAME
rsyslog.conf - rsyslogd(8) configuration fileDESCRIPTION
The rsyslog.conf file is the main configuration file for the rsyslogd(8) which logs system messages on *nix systems. This file specifies rules for logging. For special features see the rsyslogd(8) manpage. Rsyslog.conf is backward-compatible with sysklogd's syslog.conf file. So if you migrate from sysklogd you can rename it and it should work.Note that this version of rsyslog ships with extensive documentation in html format. This is provided in the ./doc subdirectory and probably in a separate package if you installed rsyslog via a packaging system. To use rsyslog's advanced features, you need to look at the html documentation, because the man pages only cover basic aspects of operation.
MODULES
Rsyslog has a modular design. Consequently, there is a growing number of modules. See the html documentation for their full description.
- omsnmp
- SNMP trap output module
- omgssapi
- Output module for GSS-enabled syslog
- ommysql
- Output module for MySQL
- omrelp
- Output module for the reliable RELP protocol (prevents message loss). For details, see below at imrelp and the html documentation. It can be used like this:
- *.* :omrelp:server:port
- *.* :omrelp:<IP_ADDRESS>:2514 # actual sample
- ompgsql
- Output module for PostgreSQL
- omlibdbi
- Generic database output module (Firebird/Interbase, MS SQL, Sybase, SQLite, Ingres, Oracle, mSQL)
- imfile
- Input module for text files
- imudp
- Input plugin for UDP syslog. Replaces the deprecated -r option. Can be used like this:
- $ModLoad imudp
- $UDPServerRun 514
- imtcp
- Input plugin for plain TCP syslog. Replaces the deprecated -t option. Can be used like this:
- $ModLoad imtcp
- $InputTCPServerRun 514
- imrelp
-
- Input plugin for the RELP protocol. RELP can be used instead of UDP or plain TCP syslog to provide reliable delivery of syslog messages. Please note that plain TCP syslog does NOT provide truly reliable delivery, with it messages may be lost when there is a connection problem or the server shuts down. RELP prevents message loss in those cases. It can be used like this:
- $ModLoad imrelp
- $InputRELPServerRun 2514
- imgssapi
- Input plugin for plain TCP and GSS-enable syslog
- immark
- Support for mark messages
- imklog
- Kernel logging. To include kernel log messages, you need to do
-
$ModLoad imklog
Please note that the klogd daemon is no longer necessary and consequently no longer provided by the rsyslog package.
- imuxsock
- Unix sockets, including the system log socket. You need to specify
-
$ModLoad imuxsock
in order to receive log messages from local system processes. This config directive should only left out if you know exactly what you are doing.
BASIC STRUCTURE
Lines starting with a hash mark ('#') and empty lines are ignored. Rsyslog.conf should contain following sections (sorted by recommended order in file):
- Global directives
-
Global directives set some global properties of whole rsyslog daemon, for example size of main
message queue ($MainMessageQueueSize), loading external modules ($ModLoad) and so on.
All global directives need to be specified on a line by their own and must start with
a dollar-sign. The complete list of global directives can be found in html documentation in doc
directory or online on web pages.
- Templates
-
Templates allow you to specify format of the logged message. They are also used for dynamic
file name generation. They have to be defined before they are used in rules. For more info
about templates see TEMPLATES section of this manpage.
- Output channels
-
Output channels provide an umbrella for any type of output that the user might want.
They have to be defined before they are used in rules. For more info about output channels
see OUTPUT CHANNELS section of this manpage.
- Rules (selector + action)
-
Every rule line consists of two fields, a selector field and an action field. These
two fields are separated by one or more spaces or tabs. The selector field specifies
a pattern of facilities and priorities belonging to the specified action.
SELECTORS
The selector field itself again consists of two parts, a facility and a priority, separated by a period ('.'). Both parts are case insensitive and can also be specified as decimal numbers, but don't do that, you have been warned. Both facilities and priorities are described in syslog(3). The names mentioned below correspond to the similar LOG_-values in /usr/include/syslog.h.
The facility is one of the following keywords: auth, authpriv, cron, daemon, kern, lpr, mail, mark, news, security (same as auth), syslog, user, uucp and local0 through local7. The keyword security should not be used anymore and mark is only for internal use and therefore should not be used in applications. Anyway, you may want to specify and redirect these messages here. The facility specifies the subsystem that produced the message, i.e. all mail programs log with the mail facility (LOG_MAIL) if they log using syslog.
The priority is one of the following keywords, in ascending order: debug, info, notice, warning, warn (same as warning), err, error (same as err), crit, alert, emerg, panic (same as emerg). The keywords error, warn and panic are deprecated and should not be used anymore. The priority defines the severity of the message.
The behavior of the original BSD syslogd is that all messages of the specified priority and higher are logged according to the given action. Rsyslogd behaves the same, but has some extensions.
In addition to the above mentioned names the rsyslogd(8) understands the following extensions: An asterisk ('*') stands for all facilities or all priorities, depending on where it is used (before or after the period). The keyword none stands for no priority of the given facility.
You can specify multiple facilities with the same priority pattern in one statement using the comma (',') operator. You may specify as much facilities as you want. Remember that only the facility part from such a statement is taken, a priority part would be skipped.
Multiple selectors may be specified for a single action using the semicolon (';') separator. Remember that each selector in the selector field is capable to overwrite the preceding ones. Using this behavior you can exclude some priorities from the pattern.
Rsyslogd has a syntax extension to the original BSD source, that makes its use more intuitively. You may precede every priority with an equals sign ('=') to specify only this single priority and not any of the above. You may also (both is valid, too) precede the priority with an exclamation mark ('!') to ignore all that priorities, either exact this one or this and any higher priority. If you use both extensions than the exclamation mark must occur before the equals sign, just use it intuitively.
ACTIONS
The action field of a rule describes what to do with the message. In general, message content is written to a kind of "logfile". But also other actions might be done, like writing to a database table or forwarding to another host.Regular file
Typically messages are logged to real files. The file has to be specified with full pathname, beginning with a slash ('/').Example:
- *.* /var/log/traditionalfile.log;RSYSLOG_TraditionalFormat # log to a file in the traditional format
Note: if you would like to use high-precision timestamps in your log files, just remove the ";RSYSLOG_TraditionalFormat". That will select the default template, which, if not changed, uses RFC 3339 timestamps.
Example:
- *.* /var/log/file.log # log to a file with RFC3339 timestamps
Named pipes
This version of rsyslogd(8) has support for logging output to named pipes (fifos). A fifo or named pipe can be used as a destination for log messages by prepending a pipe symbol ('|') to the name of the file. This is handy for debugging. Note that the fifo must be created with the mkfifo(1) command before rsyslogd(8) is started.Terminal and console
If the file you specified is a tty, special tty-handling is done, same with /dev/console.Remote machine
There are three ways to forward message: the traditional UDP transport, which is extremely lossy but standard, the plain TCP based transport which loses messages only during certain situations but is widely available and the RELP transport which does not lose messages but is currently available only as part of rsyslogd 3.15.0 and above.To forward messages to another host via UDP, prepend the hostname with the at sign ("@"). To forward it via plain tcp, prepend two at signs ("@@"). To forward via RELP, prepend the string ":omrelp:" in front of the hostname.
Example:
- *.* @<IP_ADDRESS>
In the example above, messages are forwarded via UDP to the machine <IP_ADDRESS>, the destination port defaults to 514. Due to the nature of UDP, you will probably lose some messages in transit. If you expect high traffic volume, you can expect to lose a quite noticeable number of messages (the higher the traffic, the more likely and severe is message loss).
If you would like to prevent message loss, use RELP:
- *.* :omrelp:<IP_ADDRESS>:2514
Note that a port number was given as there is no standard port for relp.
Keep in mind that you need to load the correct input and output plugins (see "Modules" above).
Please note that rsyslogd offers a variety of options in regarding to remote forwarding. For full details, please see the html documentation.
List of users
Usually critical messages are also directed to ``root'' on that machine. You can specify a list of users that shall get the message by simply writing ":omusrmsg:" followed by the login name. You may specify more than one user by separating them with commas (','). If they're logged in they get the message (for example: ":omusrmsg:root,user1,user2").Everyone logged on
Emergency messages often go to all users currently online to notify them that something strange is happening with the system. To specify this wall(1)-feature use an ":omusrmsg:*".Database table
This allows logging of the message to a database table. By default, a MonitorWare-compatible schema is required for this to work. You can create that schema with the createDB.SQL file that came with the rsyslog package. You can also use any other schema of your liking - you just need to define a proper template and assign this template to the action.See the html documentation for further details on database logging.
Discard
If the discard action is carried out, the received message is immediately discarded.  To do that, place the discard actions early in your log files. This often plays well with property-based filters, giving you great freedom in specifying what you do not want.Discard is just the single tilde character with no further parameters.
Example:
- *.* ~ # discards everything.
Output channel
Binds an output channel definition (see there for details) to this action. Output channel actions must start with a $-sign, e.g. if you would like to bind your output channel definition "mychannel" to the action, use "$mychannel". Output channels support template definitions like all all other actions.Shell execute
This executes a program in a subshell. The program is passed the template-generated message as the only command line parameter. Rsyslog waits until the program terminates and only then continues to run.Example:
- ^program-to-execute;template
The program-to-execute can be any valid executable. It receives the template string as a single parameter (argv[1]).
FILTER CONDITIONS
Rsyslog offers three different types "filter conditions":
* "traditional" severity and facility based selectors
* property-based filters
* expression-based filters
Blocks
Rsyslogd supports BSD-style blocks inside rsyslog.conf. Each block of lines is separated from the previous block by a program or hostname specification. A block will only log messages corresponding to the most recent program and hostname specifications given. Thus, a block which selects "ppp" as the program, directly followed by a block that selects messages from the hostname "dialhost", then the second block will only log messages from the ppp program on dialhost.Selectors
Selectors are the traditional way of filtering syslog messages. They have been kept in rsyslog with their original syntax, because it is well-known, highly effective and also needed for compatibility with stock syslogd configuration files. If you just need to filter based on priority and facility, you should do this with selector lines. They are not second-class citizens in rsyslog and offer the best performance for this job.Property-Based Filters
Property-based filters are unique to rsyslogd. They allow to filter on any property, like HOSTNAME, syslogtag and msg.A property-based filter must start with a colon in column 0. This tells rsyslogd that it is the new filter type. The colon must be followed by the property name, a comma, the name of the compare operation to carry out, another comma and then the value to compare against. This value must be quoted. There can be spaces and tabs between the commas. Property names and compare operations are case-sensitive, so "msg" works, while "MSG" is an invalid property name. In brief, the syntax is as follows:
- :property, [!]compare-operation, "value"
The following compare-operations are currently supported:
-
contains
- Checks if the string provided in value is contained in the property
isequal
- Compares the "value" string provided and the property contents. These two values must be exactly equal to match.
startswith
- Checks if the value is found exactly at the beginning of the property value
regex
- Compares the property against the provided regular expression.
Expression-Based Filters
See the html documentation for this feature.
TEMPLATES
Every output in rsyslog uses templates - this holds true for files, user messages and so on. Templates compatible with the stock syslogd formats are hardcoded into rsyslogd. If no template is specified, we use one of these hardcoded templates. Search for "template_" in syslogd.c and you will find the hardcoded ones.
A template consists of a template directive, a name, the actual template text and optional options. A sample is:
- $template MyTemplateName,\\7Text %property% some more text\\n,<options>
The "$template" is the template directive. It tells rsyslog that this line contains a template. The backslash is an escape character. For example, \7 rings the bell (this is an ASCII value), \n is a new line. The set in rsyslog is a bit restricted currently.
All text in the template is used literally, except for things within percent signs. These are properties and allow you access to the contents of the syslog message. Properties are accessed via the property replacer and it can for example pick a substring or do date-specific formatting. More on this is the PROPERTY REPLACER section of this manpage.
To escape:
% = \%
\ = \\ --> '\' is used to escape (as in C)
$template TraditionalFormat,"%timegenerated% %HOSTNAME% %syslogtag%%msg%
Properties can be accessed by the property replacer (see there for details).
Please note that templates can also by used to generate selector lines with dynamic file names. For example, if you would like to split syslog messages from different hosts to different files (one per host), you can define the following template:
- $template DynFile,/var/log/system-%HOSTNAME%.log
This template can then be used when defining an output selector line. It will result in something like "/var/log/system-localhost.log"
Template options
The <options> part is optional. It carries options influencing the template as whole. See details below. Be sure NOT to mistake template options with property options - the later ones are processed by the property replacer and apply to a SINGLE property, only (and not the whole template).Template options are case-insensitive. Currently defined are:
-
- sql
-
format the string suitable for a SQL statement in MySQL format. This will replace single
quotes ("'") and the backslash character by their backslash-escaped counterpart
("'" and "\") inside each field. Please note that in MySQL configuration, the NO_BACKSLASH_ESCAPES
mode must be turned off for this format to work (this is the default).
- stdsql
- format the string suitable for a SQL statement that is to be sent to a standards-compliant sql server. This will replace single quotes ("'") by two single quotes ("''") inside each field. You must use stdsql together with MySQL if in MySQL configuration the NO_BACKSLASH_ESCAPES is turned on.
Either the sql or stdsql option MUST be specified when a template is used for writing to a database, otherwise injection might occur. Please note that due to the unfortunate fact that several vendors have violated the sql standard and introduced their own escape methods, it is impossible to have a single option doing all the work. So you yourself must make sure you are using the right format. If you choose the wrong one, you are still vulnerable to sql injection.
Please note that the database writer *checks* that the sql option is present in the template. If it is not present, the write database action is disabled. This is to guard you against accidental forgetting it and then becoming vulnerable to SQL injection. The sql option can also be useful with files - especially if you want to import them into a database on another machine for performance reasons. However, do NOT use it if you do not have a real need for it - among others, it takes some toll on the processing time. Not much, but on a really busy system you might notice it ;)
The default template for the write to database action has the sql option set.
Template examples
Please note that the samples are split across multiple lines. A template MUST NOT actually be split across multiple lines.A template that resembles traditional syslogd file output:
-
$template TraditionalFormat,"%timegenerated% %HOSTNAME%
%syslogtag%%msg:::drop-last-lf%
A template that tells you a little more about the message:
-
$template precise,"%syslogpriority%,%syslogfacility%,%timegenerated%,%HOSTNAME%,
%syslogtag%,%msg%
A template for RFC 3164 format:
- $template RFC3164fmt,"<%PRI%>%TIMESTAMP% %HOSTNAME% %syslogtag%%msg%"
A template for the format traditionally used for user messages:
- $template usermsg," XXXX%syslogtag%%msg%r"
And a template with the traditional wall-message format:
- $template wallmsg,"\r\n\7Message from syslogd@%HOSTNAME% at %timegenerated%"
A template that can be used for writing to a database (please note the SQL template option)
-
$template MySQLInsert,"insert iut, message, receivedat values
('%iut%', '%msg:::UPPERCASE%', '%timegenerated:::date-mysql%')
into systemevents\r\n", SQL
NOTE 1: This template is embedded into core application under name StdDBFmt , so you don't need to define it.
NOTE 2: You have to have MySQL module installed to use this template.
OUTPUT CHANNELS
Output Channels are a new concept first introduced in rsyslog 0.9.0. As of this writing, it is most likely that they will be replaced by something different in the future. So if you use them, be prepared to change you configuration file syntax when you upgrade to a later release.
Output channels are defined via an $outchannel directive. It's syntax is as follows:
- $outchannel name,file-name,max-size,action-on-max-size
name is the name of the output channel (not the file), file-name is the file name to be written to, max-size the maximum allowed size and action-on-max-size a command to be issued when the max size is reached. This command always has exactly one parameter. The binary is that part of action-on-max-size before the first space, its parameter is everything behind that space.
Keep in mind that $outchannel just defines a channel with "name". It does not activate it. To do so, you must use a selector line (see below). That selector line includes the channel name plus ":omfile:$" in front of it. A sample might be:
- *.* :omfile:$mychannel
PROPERTY REPLACER
The property replacer is a core component in rsyslogd's output system. A syslog message has a number of well-defined properties (see below). Each of this properties can be accessed and manipulated by the property replacer. With it, it is easy to use only part of a property value or manipulate the value, e.g. by converting all characters to lower case.Accessing Properties
Syslog message properties are used inside templates. They are accessed by putting them between percent signs. Properties can be modified by the property replacer. The full syntax is as follows:
- %propname:fromChar:toChar:options%
propname is the name of the property to access. It is case-sensitive.
Available Properties
- msg
- the MSG part of the message (aka "the message" ;))
- rawmsg
- the message exactly as it was received from the socket. Should be useful for debugging.
- HOSTNAME
- hostname from the message
- FROMHOST
- hostname of the system the message was received from (in a relay chain, this is the system immediately in front of us and not necessarily the original sender)
- syslogtag
- TAG from the message
- programname
- the "static" part of the tag, as defined by BSD syslogd. For example, when TAG is "named[12345]", programname is "named".
- PRI
- PRI part of the message - undecoded (single value)
- PRI-text
- the PRI part of the message in a textual form (e.g. "syslog.info")
- IUT
- the monitorware InfoUnitType - used when talking to a MonitorWare backend (also for phpLogCon)
- syslogfacility
- the facility from the message - in numerical form
- syslogfacility-text
- the facility from the message - in text form
- syslogseverity
- severity from the message - in numerical form
- syslogseverity-text
- severity from the message - in text form
- timegenerated
- timestamp when the message was RECEIVED. Always in high resolution
- timereported
- timestamp from the message. Resolution depends on what was provided in the message (in most cases, only seconds)
- TIMESTAMP
- alias for timereported
- PROTOCOL-VERSION
- The contents of the PROTOCOL-VERSION field from IETF draft draft-ietf-syslog-protocol
- STRUCTURED-DATA
- The contents of the STRUCTURED-DATA field from IETF draft draft-ietf-syslog-protocol
- APP-NAME
- The contents of the APP-NAME field from IETF draft draft-ietf-syslog-protocol
- PROCID
- The contents of the PROCID field from IETF draft draft-ietf-syslog-protocol
- MSGID
- The contents of the MSGID field from IETF draft draft-ietf-syslog-protocol
- $NOW
- The current date stamp in the format YYYY-MM-DD
- $YEAR
- The current year (4-digit)
- $MONTH
- The current month (2-digit)
- $DAY
- The current day of the month (2-digit)
- $HOUR
- The current hour in military (24 hour) time (2-digit)
- $MINUTE
-
The current minute (2-digit)
Properties starting with a $-sign are so-called system properties. These do NOT stem from the message but are rather internally-generated.
Character Positions
FromChar and toChar are used to build substrings. They specify the offset within the string that should be copied. Offset counting starts at 1, so if you need to obtain the first 2 characters of the message text, you can use this syntax: "%msg:1:2%". If you do not wish to specify from and to, but you want to specify options, you still need to include the colons. For example, if you would like to convert the full message text to lower case, use "%msg:::lowercase%". If you would like to extract from a position until the end of the string, you can place a dollar-sign ("$") in toChar (e.g. %msg:10:$%, which will extract from position 10 to the end of the string).There is also support for regular expressions. To use them, you need to place a "R" into FromChar. This tells rsyslog that a regular expression instead of position-based extraction is desired. The actual regular expression must then be provided in toChar. The regular expression must be followed by the string "--end". It denotes the end of the regular expression and will not become part of it. If you are using regular expressions, the property replacer will return the part of the property text that matches the regular expression. An example for a property replacer sequence with a regular expression is: "%msg:R:.*Sev:. \(.*\) \[.*--end%"
Also, extraction can be done based on so-called "fields". To do so, place a "F" into FromChar. A field in its current definition is anything that is delimited by a delimiter character. The delimiter by default is TAB (US-ASCII value 9). However, if can be changed to any other US-ASCII character by specifying a comma and the decimal US-ASCII value of the delimiter immediately after the "F". For example, to use comma (",") as a delimiter, use this field specifier: "F,44". If your syslog data is delimited, this is a quicker way to extract than via regular expressions (actually, a *much* quicker way). Field counting starts at 1. Field zero is accepted, but will always lead to a "field not found" error. The same happens if a field number higher than the number of fields in the property is requested. The field number must be placed in the "ToChar" parameter. An example where the 3rd field (delimited by TAB) from the msg property is extracted is as follows: "%msg:F:3%". The same example with semicolon as delimiter is "%msg:F,59:3%".
Please note that the special characters "F" and "R" are case-sensitive. Only upper case works, lower case will return an error. There are no white spaces permitted inside the sequence (that will lead to error messages and will NOT provide the intended result).
Property Options
Property options are case-insensitive. Currently, the following options are defined:- uppercase
- convert property to lowercase only
- lowercase
- convert property text to uppercase only
- drop-last-lf
- The last LF in the message (if any), is dropped. Especially useful for PIX.
- date-mysql
- format as mysql date
- date-rfc3164
- format as RFC 3164 date
- date-rfc3339
- format as RFC 3339 date
- escape-cc
- replace control characters (ASCII value 127 and values less then 32) with an escape sequence. The sequence is "#<charval>" where charval is the 3-digit decimal value of the control character. For example, a tabulator would be replaced by "#009".
- space-cc
- replace control characters by spaces
- drop-cc
-
drop control characters - the resulting string will neither contain control characters, escape sequences nor any other replacement character like space.
QUEUED OPERATIONS
Rsyslogd supports queued operations to handle offline outputs (like remote syslogd's or database servers being down). When running in queued mode, rsyslogd buffers messages to memory and optionally to disk (on an as-needed basis). Queues survive rsyslogd restarts.It is highly suggested to use remote forwarding and database writing in queued mode, only.
To learn more about queued operations, see the html documentation.

The key management procedures should require the keys to be changed at least annually.
Changing encryption keys periodically makes it more difficult for an attacker to get access to a valid key.
Check the key management procedures in the information security policy to make sure they require the encryption keys to be changed at least annually.
Add a requirement to change the encryption at least annually to the information security policy as a part of the key management procedures. Change the encryption keys at least once a year.

Open Source Policy
The developers at FINN.no are encouraged to use open source software. We benefit
from freedom to review the source code, fix errors, and improve the code. Active
participation in the open source community is valuable not only to FINN's employees,
public image, hiring, and karma; it also improves the source code and adds value for
everyone.
Use of Open Source Software
All changes we make to an open source project must be committed back to the
project.
Changes to open source code that are deemed unsuitable for sharing must lead to a
design review. This design is strongly recommended to be changed in order to be
more suitable for contribution back to the project.
Publishing of Open Source Software
FINN encourages publishing of open source code. This leads to:
- Better code quality
- Higher developer competence
- Positive FINN branding
- Easier reuse of software across Schibsted
Code written by employees at FINN on company time belongs to FINN and cannot
be freely distributed without permission. Consider the size and scope of the code,
and consult with your nearest leader or the Enterprise Architect group. The EA group
may escalate to the Chief Technology Officer (CTO).
An overview must be maintained in each repository. This overview must contain:
- A primary maintainer / owner in the README
- Names of the involved employees in the README
- A brief description of the project (typically a URL) in the README
- Which licence the code is published under in the LICENSE file
The maintainer of the project must
- Answer pull requests and issues
- Decide if the project is maintained or should be archived
- Keep the code and libraries up to date
To be published, code must bring value to:
- FINN
- The Open Source community
When forking an external project, the fork should be made in FINN’s organization
only if we intend to maintain the fork. If the fork is made only for submitting a fix, the
fork should be made on the user’s own profile.
Published code must NOT:
- Contain business critical information
- Breach contracts or agreements between FINN and FINN's users or customers
- Contain information that may lead to weakened integrity for FINN's users or
customers
- Contain information that may lead to weakened security of FINN's data, users, or
customers
Maintenance of Open Source Software
Published code must have at least one maintainer at FINN. The maintainer must
show the project love. If the maintainer stops loving their project, or leaves FINN, the
maintainer must either find a replacement maintainer (not necessarily within FINN),
or declare the project inactive/end-of-life/dead. FINN should have a process
(preferably automated) to catch projects where the maintainer is no longer
associated with FINN.
Smaller projects should be published under the FINN organization on GitHub
(https://github.com/finn-no). Larger projects consisting of multiple repositories may
be candidates for separate organizations, with a clear reference to FINN.no.
Open Source Licenses
Code must be published under licences approved and deemed popular by OSI
(www.opensource.org). The licence must not hinder FINN's opportunities to further
develop the code so that a later version cannot be published. Normally, code shall
be published under MIT. If the project incorporates FINN branding elements like
color schemes, fonts and logos, use the Apache License 2.0.
Sponsoring of Open Source
FINN is positive towards monetary sponsoring of open source projects. Decisions to
sponsor (and the exact sum to sponsor with) must be determined on a case-by-case
basis by the Technology Leader Group (TLG).

Global hotkeys are very handy when your application should be accessible at all time. For instance, you are browsing the Web and suddenly want to e-mail your friend. The most convenient way to do so would be to press a shortcut and the e-mail client would popup with a "new message" window no matter what program you are using at the time. This can be done with global shortcuts. They are system-wide no matter if the program you are using uses the same shortcut. A global shortcut is more important.
Here's the code to register and unregister a global shortcut.
uses Messages, Windows; ... // Your main form's class protected procedure WMHotKey(var Message: TMessage); message WM_HOTKEY; ... implementation ... procedure TMainForm.WMHotKey(var Message: TMessage); begin // This example brings the application up front. Put your code here Application.BringToFront; end;
Example of use:
RegisterHotKey(Handle, 100000 { Any unused number}, MOD_CONTROL, VK_F7); // When closing program UnregisterHotKey(Handle, 100000);

EVEN COWGIRLS GET THE BLUES A Film Review by James Berardinelli Copyright 1994 James Berardinelli
Rating (0 to 10): 1.5
Date Released: 5/20/94 Running Length: 1:42 Rated: R (Language, sex, mature themes)
Starring: Uma Thurman, John Hurt, Rain Phoenix, Lorraine Bracco, Noriyuki "Pat" Morita, Keanu Reeves, Angie Dickenson Director: Gus Van Sant Producer: Laurie Parker Screenplay: Gus Van Sant based on the novel by Tom Robbins Music: k.d. lang and Ben Mink Released by Fine Line Features
Anyone following the behind-the-scenes history of EVEN COWGIRLS GET THE BLUES knew that the film was in trouble long before its release. Following a negative reaction at last year's Toronto Film Festival, director Gus Van Sant (DRUG STORE COWBOY, MY PRIVATE IDAHO) went back to the editing room to recut the picture, hoping to supply more life and coherency than was evident his first take. It didn't work. EVEN COWGIRLS is as close to an unwatchable film as there is available at this time in the theaters.
Perhaps I might be more sympathetic had I read Tom Robbins' 1976 book - the "first hippie novel", as Van Sant calls it - but I haven't, so I'll leave the comparisons to someone else. Whether or not this is the 90s version of BONFIRE OF THE VANITIES remains to be seen, although cinematically, it's certainly on the same level.
Uma Thurman plays Sissy Hankshaw, a loopy drifter who hitchhikes her way across the country from adventure to adventure. A letter from her old friend the Countess (played by a cross-dressing John Hurt) summons her to New York, where she meets with an asthmatic artist (Keanu Reeves) and is offered a job doing an ad campaign for the Countess' midwestern ranch - which is really a fat farm/beauty spa. Once she arrives in Oregon, however, the cowgirl workers, led by Bonanza Jellybean (Rain Phoenix) stage a coup and take over the property, running the Countess and her rich clients out. This provokes an armed federal response, and one of the most laughably idiotic denouements in recent film history.
Where to begin...
Even if the plot made sense (which it really doesn't) and wasn't unbelievably contrived (which it is), EVEN COWGIRLS is difficult to follow because of its disjointed nature. Whether this is a result of poor editing, confused writing, or (most likely) a combination of the two, the result is obvious - a chaotic motion picture that never finds its focus and is agonizing to sit through.
Sissy, the main character, is bland, although through no fault of Uma Thurman, whose performance is reasonably restrained in the midst of a festival of scenery-chomping. The problem with Sissy is that Van Sant never forges a connection between her and the audience. There is no emotional link, and the viewer isn't likely to care any more about her at the end than at the beginning.
With the notable exception of that given by Thurman, the performances are awful. Lorraine Bracco (who I don't consider to be a good actor) and John Hurt (who I do) go so far over the top that you wonder if they'll ever reach bottom. Rain Phoenix (the sister of the late River Phoenix, to whom this film is dedicated) isn't much better, probably because she doesn't know how to act.
The dialogue, especially the Tom Robbins-supplied voiceovers, is grating. There's too much pretension and posturing here, and a typical conversation consists of characters trying to one-up each other in the number of meaningless profundities they can spew out. This is probably supposed to make the viewer ponder; amidst all the other garbage that comprises EVEN COWGIRLS, it just made me reel.
The themes presented by the movie - feminism and the rights of the individual - have a heavy 70s flavor that Van Sant has done nothing to update. In a rare case of getting something right, at least EVEN COWGIRLS gives a natural, non-exploitative view of lesbian love.
Then there are Sissy's thumbs. Supposedly incredibly long and supple, these represent a botch-up by the prosthetics and make-up department. Every time Sissy sticks out these monstrosities to hitch a ride, the viewer's eyes are glued to them - not because of some inner desire to gape at the deformity, but because they look so fake.
Further rumination on EVEN COWGIRLS is probably as pointless as the film itself. The only possible reason to see it is to experience firsthand how badly a moderately-budgeted art film can go wrong. In some sense, it's hard to believe that this much talent can produce something so worthless. That's enough to give anyone the blues.

Hello, dahling. My name is Jenna Cooper, and I'm happy you've stopped by. To say that I "do" a particular thing would be misleading, as I have done many. Overall, I consider myself to be very well-rounded, when it comes to my educational background and work experience. After graduating with a degree in psychology and a minor in journalism, I decided to pursue a lifelong dream of acting in the City of Angels. In addition to acting, I have always had a great love for writing; and, I am gradually writing a book in creative non-fiction.
Career-wise, I have chosen to explore many arenas, which has led me to be the person I am, today. I have dabbled into the roles of: actress, waitress, hostess, office assistant, assistant to the VP of finance, sales associate at a multitude of high-end retailers (e.g., Nordstrom, GUESS?, Marciano, LF Boutiques, Tiffany, Neiman Marcus), preschool teacher, promotional model (e.g., brand ambassador), and flight attendant. My background has enabled me to become comfortable and confident, when it comes to connecting to people with a wide-range of personalities. I have a great love for people, and one of my top strengths is empathy.
Due to my great love of writing, I began a blog that I created and wrote on for over 3.5 years. During that time (circa 2010), I began teaching myself about CSS, html, blogging platforms, GoDaddy, domain names, Wordpress, and the likes. Ever since, during spare time, I am almost always on my MacBook, exploring the world inside a computer. Ultimately, this is what led me to Epicodus and the CSS/Design Track. Aside from my love of blogging and the internet, I have been known as an all-too-curious person to those whom I am closest to. That said, I chose to embark upon the world of coding. ...Stepping inside a whole new world is the least bit "new" to me; nevertheless, I have immense admiration for every single one of my peers, as I can most definitely say this isn't a world in which fear can thrive.

Bitcoin is Speculation and Not the Future of Money, Ex-ECB Chief Says
by Anatol AntonoviciJean-Claude Trichet, former president of the European Central Bank (ECB), said that he was strongly against Bitcoin and hinted that cryptocurrency purchases are no more than speculation, South China Morning Post reported on Sunday.
Bitcoin is Not Real
Speaking at the Caixin’s 10th annual conference in Beijing, Trichet said he was doubtful that Bitcoin and cryptocurrencies are the future of money. He stated:
“I am strongly against bitcoin, and I think we are a little complacent. The [crypto]currency itself is not real, with the characteristics that a currency must have.”
Buying Bitcoin or any other cryptocurrency is more about speculation, according to him.
“Even if [the cryptocurrency] is supposed to be based on underlying assets, I am observing a lot of speculation. It is not healthy,” the ex-ECB chief added.
While Trichet admits that the world is moving away from hard money, i.e. physical coins and banknotes, he doesn’t think the direction points to cryptocurrency. Instead, he would prefer the so-called Special Drawing Rights (SDR), a monetary instrument created by the International Monetary Fund (IMF). This unit of account is backed by a basket of fiat currencies, including the US dollar, the euro, the British pound, the yen, and the Chinese renminbi.
“I have great doubts of keeping control of monetary value in [the cryptocurrency] domain. In the so-called new stable international currencies … the SDR would be the right basket.”
Trichet was at the head of the ECB from 2003 to 2011. Previously, he was governor of the Bank of France. On a side note, the French central bank recently admitted that it considered Bitcoin investments as speculation.
Current ECB President Endorses Cryptos
Interestingly, the current ECB head, Christine Lagarde, has a history of making crypto-supportive statements on various occasions.
Ironically, she is the former head of the IMF, the creator of the SDR tool, which Trichet loves so much.
In September of this year, Lagarde hinted that central banks should be more open to cryptocurrencies.

WAG THE DOG ** 1/2. Directed by Barry Levinson. Written by Hilary Henkin & David Mamet from the book "American Hero" by Larry Beinhart. Photography, Robert Richardson. Production design, Wynn Thomas. Editing, Stu Linder. Music, Mark Knopfler. Cast: Dustin Hoffman, Robert De Niro, Anne Heche, Denis Leary, Willie Nelson, Woody Harrelson (uncredited), et al. A New Line release. 93 min. Rated R (language).
At any given moment movie genres come in twos, threes or in wolfpacks.  The title "Wag the Dog" suggests another kiddie movie about a friendly hound, It is not. It's an adult (sort of) satire of politics, Hollywood, and the media. And although beautifully acted and intermittently quite funny, I find that its premise is mean and opportunistic as the inspiration obviously comes from headlines about President Clinton. It is all the stranger since, chances are, the filmmakers are Democrats.
The President of the United States has been charged by a young girl of molesting her when she was touring the White House with a group of Firefly Girls, whatever those are. By the horniest stretch of imagination, the accusation is unbelievable, but as the country is only days away from an election, it can do irreparable harm.
The President is away in China (collecting Chinese votes???!!!). His desperate aide Winifred Ames (Heche) calls Conrad Brean (De Niro) to a top secret meeting in a White House bunker. Brean, a Mr. Fixit spin doctor opts for a major diversion. He enlists Hollywood producer Stanley Motss, pronounced Moss (Hoffman) to fabricate an imaginary war with Albania --a ludicrous, farcical yet clever choice given America's ignorance of geography. The conflict comes complete with phony documentary footage made easy (and funny) by digital techniques. It includes references to a nonexistent new bomber (an airplane that is). A country singer (Willie Nelson) is hired to write a patriotic parody of "We Are the World" that massed choirs perform.
In its last section the plot somehow gets lost. The end of the "crisis" tries to top the fabulation with a returning war hero who is not what was expected. This is a strictly from hunger development, though Woody Harrelson has memorable presence. They baptize him Schumann (read Shoe Man) and incite the public to pepper the country with symbolic shoes (sic).
The hoodwinking of an entire nation is imaginative but never gives you a chance to suspend your disbelief. The eagerness of the media, especially TV, to swallow and disseminate the "news," the gullibility of the nation and its leaders, the cooperation of the military go from very, very, very marginally believable to incredible..
The other element is the comically exaggerated. But whereas in a gem like "Dr. Strangelove" the roles are out and out caricatural, here their outrageousness is semi-realistic as both Washington and Hollywood converge in their belief that, in De Niro's words, "war is show business." Dustin Hoffman, in his physical and temperamental likeness to and parody of the outrageous producer Robert Evans, merely pushes the envelope, which he does with great gusto. With frantic pacing and faster and faster talk (a contemporary variant of Howard Hawks' screwball comedies), under the lead of he agitated Hoffman and the unflappable De Niro, there is an avalanche of in-jokes about movie-makers and politicos.
What motivates Hoffman is twofold: his gripe that producers don't get Oscars, and his compulsion to produce the Himalaya of his career. This is amusing, up to a point. The yak yak however tries to pack too many esoteric references that contribute to some troughs of monotony. The dog barks but does not bite, the film does not open eyes or soar to a higher level. Its parts can be entertaining but their sum stays on the ground.

BLINKS Trend that #BLACKPINKLEAVEYG
by rosieslalisaBlinks have yet again called out YG Entertainment’smistreatment toward their one and only Girl Group- BLACKPINK.
On Wednesday evening, YG Entertainment confirmed that their groupSechskies is preparing a comeback,but that the timeframe was not yet decided. It was also said that ”The comeback of girl group BLACKPINK is likely to be delayed until next year”. This statement upset many Blinks, as it seems YG entertainment has failed to fulfill their 2019 plans for BLACKPINK, seen in the photo below-
As it is already mid-November, it seems irrational and unlikely that YG entertainment would be able to complete their promises. BLACKPINK have not had two comebacks in one year since their debut year of 2016. Since the release of “As If Its Your Last” in 2017, BLACKPINK have received one, often rushed, comeback. This has upset fans as if they feel BLACKPINK are not getting the opportunities that they deserve. They currently have the highest selling physical album of all time throughout YG Entertainment’s history with their “Kill This Love” mini album, which only came with four new songs. It is very confusing as why YG Entertainment wouldn’t invest more into what seems to be their most profitable current act. A photo of YG Entertainment’s 2019 album sales can be see below-
Besides trending the hashtag, BLINKS have also had talks about purchasing billboards near the YG Entertainment headquarters in Korea, demanding for a comeback. Whether or not this occurs, it seems as if they’re willing to try anything for YG Entertainment to take notice and acknowledge their concerns. In the past, they even created a petition that garnered over 50,000 signatures. In the end, YG Entertainment failed to even simply acknowledge the petition.
Blinks were also upset when the official YG twitter account posted the tweet below. They felt as if YG Entertainment was taking away the credit from BLACKPINK and putting it onto themselves, even though they do little to nothing to help BLACKPINK’s career.
YG Entertainment later went and changed the tweet, mentioning BLACKPINK instead of using the term “we”. This also upset fans, as they realized that YG Entertainment do in-fact see their tweets and concerns regarding BLACKPINK’s lack of music and promotion, but they continue to do nothing about it.
It is not just BLINKS themselves, but also the members of BLACKPINK have expressed concern regarding their lack of music. See the photos below-
There is no other conclusion to come to regarding YG Entertainment’s treatment towards BLACKPINK other than misogyny. It seems that no matter what BLACKPINK achieve or what records they break, it will never be enough for the company. It is disheartening to watch these girls talents and skills go to waste. It is in best hope that YG Entertainment will change their ways and management towards BLACKPINK, especially when the company is in harsh times, making little to no profit.
We hope to see an increase in the release of BLACKPINK music and promotions in the future.

Boids: A Bird Flock Simulator
Demo // GitHub Repo
Boids are a simulation program, originally conceived by Craig Reynolds, to model the cooperative movement of animals in nature, like flocks of birds and schools of fish.
Boids are fascinating, because from the application of a few simple rules to a group of entities, complex coordinated behavior emerges.
Conrad Parker has written an excellent resource on how to code the simulation using psuedocode, which will allow you to reproduce the simulation in your own language of choice.
Here, we’ll use vanilla JavaScript and an HTML canvas to visualize the flock.
Vectors and Scalars
A brief introduction to terms.
- Scalars: represent a magnitude
- Vectors: represent direction as well as magnitude
The classic examples are speed and velocity.
Imagine you’re driving a car, and you give me your current position on a map and tell me you’re going 55 miles per hour.
I know how much distance you’re covering in a given time, but I have no idea where you’re going toward or coming from.
On the other hand, if you tell me that you’re traveling 55 miles per hour (direction) and that you’re going north on I-5 (magnitude), I can tell you where you’ll be in a given period of time, given your starting position.
But “north on I-5” is too specific. To capture the notion of direction and magnitude in the abstract, vectors have a coordinate for each direction of motion.
For a 2-dimensional vector, there is an X-component and a Y-component. For a 3-D vector, there is also a Z-component.
JavaScript has numbers to handle scalars, no problem. There’s no built in Vector object though, so let’s make one now to handle our 2D vectors.
function V2(x, y) {
// 2D vector class
this.x = x || 0;
this.y = y || 0;
this.add = (addedVector) =>
new V2(this.x + addedVector.x, this.y + addedVector.y);
this.subtract = (subtractedVector) =>
new V2(this.x - subtractedVector.x, this.y - subtractedVector.y);
this.multiply = (magnitude) =>
new V2(this.x * magnitude, this.y * magnitude);
this.magnitude = () =>
Math.sqrt(Math.pow(this.x, 2) + Math.pow(this.y, 2));
}
We intialize the default x and y copmonent to 0 and add four methods.
Addition
To add two vectors, you simply create a new vector, where each component is the sum of the added vectors' components.
For instance: [1, 2] + [3, 4]
=> [4, 6]
Subtraction
Subtraction is the inverse of addition. Just subtract instead.
For instance: [1, 2] - [3, 4]
=> [-2, -2]
Multiplication
To multiply a vector by a scalar, create a new vector with each component multiplied by the scalar.
For instance: [1, 2] * -1
=> [-1, -2]
Magnitude
To calculate magnitude, we use the Pythagorean Theorum: the magnitude of a vector is equal to the square root of the sum of the squares of each component.
For instance: [-1, 2] => sqrt(-1 * -1 + 2 * 2) => sqrt(5)
Boids
Now that we have vectors, we can make boids.
Boids have positions and velocities. We also want to be able to identify individual boids. To do this, we can create an autoincrementing instance count on the Boid object.
Velocity is the change of position over time (distance / time). Acceleration is the change of velocity over time (distance / time * 2). You can describe this using calculus (integrating the velocity over a time interval gives the distance travelled), but for our simulation, all this means is that if we update at a constant frames-per-second, we can update the position by adding the change in velocity over that time interval.
function Boid(initialPosition, initialVelocity) {
this.position = initialPosition || new V2(0, 0);
this.velocity = initialVelocity || new V2(0, 0);
Boid.numInstances = (Boid.numInstances || 0) + 1;
this.id = Boid.numInstances; // autoincrementing unique ID
}
Rules for Boid Behavior
Each of these rules considers an individual boid
with respect to the group of all boids boidList
, an array of boid
s.
Each rule returns a velocity vector.
1. Boids try to align themselves with the average position of the flock
First, we calculate the average position of the flock (excluding the current boid). We calculate this just like any other average: sum each vector and then divide by the length of the list of boids (minus one, because we’re excluding the current boid).
We subtract the current boid’s position from the average position. This generates a vector pointing from the current boid to the average position of the flock.
Finally, we multiply this alignment vector by a COHESION_FACTOR
: this can be used to temper the effect of the forced alignment.
function rule1(boid, boidList) {
// Boids try to align themselves with the average position of the flock
let theOtherBoids = boidList.filter((boidId) => boid.id != boidId.id);
let avgPosition = new V2();
theOtherBoids.forEach(
(boid) => (avgPosition = avgPosition.add(boid.position))
);
return avgPosition
.multiply(1 / theOtherBoids.length - 1)
.subtract(boid.position)
.multiply(COHESION_FACTOR);
}
2. Boids try to maintain a minimum distance between themselves and others
We can set a constant TOO_CLOSE_MAGNITUDE
that the boids will use to figure out if they are too close to one another. First, we make a list of the boids that the current boid is too close too. For each boid that’s too close, we generate a vector pulling this boid away from these boids.
function rule2(boid, boidList) {
// Boids try to maintain a minimum distance between themselves and others
let newPositionVector = new V2();
boidList
.filter((boidId) => boid.id !== boidId.id)
.map((otherBoid) => otherBoid.position)
.filter(
(otherBoidPosition) =>
otherBoidPosition.subtract(boid.position).magnitude() <
TOO_CLOSE_MAGNITUDE
)
.map((tooCloseBoid) =>
newPositionVector.subtract(tooCloseBoid.subtract(boid.position))
);
return newPositionVector;
}
3. Boids try to match their velocity with that of the flock
We can calculate the average velocity in the same way that we calculated average position. Then, multiply by a VELOCITY_MATCH_FACTOR
.
function rule3(boid, boidList) {
// Boids try to match their velocity with that of the flock
return boidList
.filter((boidId) => boid.id !== boidId.id)
.map((otherBoid) => otherBoid.velocity)
.reduce((boidA, boidB) => boidA.add(boidB), new V2())
.multiply(1 / boidList.length - 1)
.multiply(VELOCITY_MATCH_FACTOR);
}
Simulation
Set up a Canvas
<canvas id="birdflock"></canvas>
We’ll make the canvas the height & width of the window with 100 pixel margins.
ctx.translate(0.5, 0.5)
moves the canvas grid by a half-pixel for smoothing.
If you have a retina display, canvas pixels look weird unless you scale them down by a factor of 2. So, we’ll use a scaleFactor
of the pixel ratio (2x for retina, 1x for non-retina) to augment our calculations.
const scaleFactor = window.devicePixelRatio;
const MAX_X = window.innerWidth * scaleFactor - 100;
const MAX_Y = window.innerHeight * scaleFactor - 100;
c = document.getElementById("birdflock");
c.width = MAX_X;
c.height = MAX_Y;
c.style.width = `${c.width / scaleFactor}px`;
c.style.height = `${c.height / scaleFactor}px`;
ctx = c.getContext("2d");
ctx.translate(0.5, 0.5);
ctx.scale(scaleFactor, scaleFactor);
Teach the Boids to Draw Themselves
We can make each boid draw itself by just generating a rectangle on the canvas based on the boid’s x and y coordinates (taking into account the scaleFactor
of devicePixelRatio):
this.draw = (ctx) => {
ctx.fillStyle = "gold";
ctx.fillRect(
this.position.x / scaleFactor,
this.position.y / scaleFactor,
BOID_WIDTH,
BOID_HEIGHT
);
};
Introduce the element of time
Now that we have Boids and rules for their behavior, we have to introduce an element of time into our simulation. We can do this using window.requestAnimationFrame
.
In each tick of time, we’ll first check to see if we should draw a frame, based on our fpsInterval
, which is 1000ms / frames-per-second. If we haven’t reached this amount of time since we last drew, we’ll do nothing.
The main loop looks like this:
// How to know if we should draw in the next frame we're given
let then = Date.now();
function step() {
window.requestAnimationFrame(step);
now = Date.now();
elapsed = now - then;
if (elapsed < fpsInterval) {
return;
}
then = now - (elapsed % fpsInterval);
ctx.clearRect(0, 0, c.width, c.height);
ctx.fillStyle = "black";
ctx.fillRect(0, 0, c.width, c.height);
updateBoidPositions(boidList);
drawBoidList(boidList, ctx);
}
With each tick we:
- clear the canvas and paint it black
- call
updateBoidPositions
, which applies the rules to each boid, and then performs a final adjustment to make sure the boid isn’t off screen - tell the boids to draw themselves
Refining boid behavior
It helps to impose a velocity limit on the boids, so that the flocks do not hurt your eyes as they flutter about. VELOCITY_LIMIT
is a constant, and limitVelocity
can be called on the resultant velocity:
const limitVelocity = (v) =>
v.magnitude() > VELOCITY_LIMIT
? v.multiply(1 / (v.magnitude() * VELOCITY_LIMIT))
: v;
In addition, in order to keep the boids within the viewport (the part of the screen that we display on the canvas), we have to limit their coordinates to the bounds of the viewport.
So, in each frame, for each boid, we’ll make sure the X and Y coordinates are greater than zero, and we’ll make sure that the X and Y coordinates are less than some maximum value (in this case, the width and height of the viewport).
So that the boid doesn’t go all the way off the screen, we’ll make the bounds slightly smaller, by a factor of the BOID_WIDTH and BOID_HEIGHT for the X and Y components, respectively.
If the boid is out of bounds on either axis, we apply an opposing factor to the velocity FLINGBACK_VELOCITY
and multiply by -1 if the value is too large.
this.normalizePosition = (maxX, maxY) => {
// If it's too far left or too far right
if (this.position.x < BOID_WIDTH) {
this.velocity.x += FLINGBACK_VELOCITY;
} else if (this.position.x > MAX_X - BOID_WIDTH) {
this.velocity.x += -1 * FLINGBACK_VELOCITY;
}
// Or too far up or too far down
if (this.position.y < 5 - BOID_HEIGHT) {
this.velocity.y += FLINGBACK_VELOCITY;
} else if (this.position.y > MAX_Y - BOID_HEIGHT) {
this.velocity.y += -1 * FLINGBACK_VELOCITY;
}
};
In each tick, to update the positions we just apply the 3 rules to each boid. This gives us the new vector for that boid. We add it, and then we make sure the boid’s not now going too fast or flying off of the screen:
function updateBoidPositions(boidList) {
boidList.forEach((boid) => {
boid.velocity = limitVelocity(
boid.velocity.add(
rule1(boid, boidList)
.add(rule2(boid, boidList))
.add(rule3(boid, boidList))
)
);
// Add the calculated ∆velocity to get the new position
boid.position = boid.position.add(boid.velocity);
// Make sure we aren't making the boids go off into the ether
boid.normalizePosition(MAX_X, MAX_Y);
});
}
Conveniently, boids know how to draw themselves, so to draw them all:
const drawBoidList = (boidList, ctx) =>
boidList.forEach((boid) => boid.draw(ctx));
Starting the simulation
We need to generate some random boids and then feed them to the loop we wrote.
We’ll make a function to generate boids up to BOID_START_CT
with a random position (though roughly at the center of the screen) and a random velocity. These parameters are set up so that the boids are initially flying in opposite directions.
function fillBoidList() {
// Make some random boids
let list = [];
for (var i = 0; i < BOID_START_CT; i++) {
// Give a little randomization
let dir = Math.random() > 0.5 ? 1 : -1;
const initialPosition = new V2(
MAX_X / 2 + Math.random() * 25,
MAX_Y / 2 + Math.random() * 25
);
const initialVelocity = new V2(
2 * Math.random() * dir,
2 * Math.random() * dir
);
list.push(new Boid(initialPosition, initialVelocity));
}
return list;
}
Then, to kick the whole thing off:
let animFrameHandler;
function resetBoidsAndStartAnimationFrames() {
if (animFrameHandler) {
window.cancelAnimationFrame(animFrameHandler);
}
boidList = fillBoidList();
animFrameHandler = window.requestAnimationFrame(step);
}
function fly() {
setUpWindow();
resetBoidsAndStartAnimationFrames();
}
// Kick off the simulation
document.addEventListener("DOMContentLoaded", fly);
More ideas
In my CodePen, I added some sliders so that you can vary the the rule’s parameter factors dynamically, adjust the frames-per-second, and a reset button to start again from scratch.
Conrad Parker's paper details some of these ideas. You could try:
- introducing a wind as a constant vector for all the boids in the flock
- setting up obstacles for boids to fly around
- have the canvas react to mouse clicks to generate or direct flocks
- add another dimension and use https://threejs.org/ to make a VR simulation
