ff: Memory-Efficient Storage of Large Data on Disk and Fast Access
Functions
The ff package provides data structures that are stored on
disk but behave (almost) as if they were in RAM by transparently
mapping only a section (pagesize) in main memory - the effective
virtual memory consumption per ff object. ff supports R's standard
atomic data types 'double', 'logical', 'raw' and 'integer' and
non-standard atomic types boolean (1 bit), quad (2 bit unsigned),
nibble (4 bit unsigned), byte (1 byte signed with NAs), ubyte (1 byte
unsigned), short (2 byte signed with NAs), ushort (2 byte unsigned),
single (4 byte float with NAs). For example 'quad' allows efficient
storage of genomic data as an 'A','T','G','C' factor. The unsigned
types support 'circular' arithmetic. There is also support for
close-to-atomic types 'factor', 'ordered', 'POSIXct', 'Date' and
custom close-to-atomic types.
ff not only has native C-support for vectors, matrices and arrays
with flexible dimorder (major column-order, major row-order and
generalizations for arrays). There is also a ffdf class not unlike
data.frames and import/export filters for csv files.
ff objects store raw data in binary flat files in native encoding,
and complement this with metadata stored in R as physical and virtual
attributes. ff objects have well-defined hybrid copying semantics,
which gives rise to certain performance improvements through
virtualization. ff objects can be stored and reopened across R
sessions. ff files can be shared by multiple ff R objects
(using different data en/de-coding schemes) in the same process
or from multiple R processes to exploit parallelism. A wide choice of
finalizer options allows to work with 'permanent' files as well as
creating/removing 'temporary' ff files completely transparent to the
user. On certain OS/Filesystem combinations, creating the ff files
works without notable delay thanks to using sparse file allocation.
Several access optimization techniques such as Hybrid Index
Preprocessing and Virtualization are implemented to achieve good
performance even with large datasets, for example virtual matrix
transpose without touching a single byte on disk. Further, to reduce
disk I/O, 'logicals' and non-standard data types get stored native and
compact on binary flat files i.e. logicals take up exactly 2 bits to
represent TRUE, FALSE and NA.
Beyond basic access functions, the ff package also provides
compatibility functions that facilitate writing code for ff and ram
objects and support for batch processing on ff objects (e.g. as.ram,
as.ff, ffapply). ff interfaces closely with functionality from package
'bit': chunked looping, fast bit operations and coercions between
different objects that can store subscript information ('bit',
'bitwhich', ff 'boolean', ri range index, hi hybrid index). This allows
to work interactively with selections of large datasets and quickly
modify selection criteria.
Further high-performance enhancements can be made available upon request.

YOU ONLY LIVE TWICE (1967) A film review by James Berardinelli Copyright 1996 James Berardinelli
RATING (0 TO 10): 6.3 Alternative Scale: **1/2 out of ****
United Kingdom, 1967 Running Length: 1:56 MPAA Classification: PG (Sexual innuendo, violence) Theatrical Aspect Ratio: 2.2:1
Cast: Sean Connery, Donald Pleasence, Akiko Wakabayashi, Tetsuro Tamba, Mie Hama, Bernard Lee, Desmond Llewelyn, Lois Maxwell Director: Lewis Gilbert Producer: Albert R. Broccoli and Harry Saltzman Screenplay: Roald Dahl based on the novel by Ian Fleming Cinematography: Freddie Young Music: John Barry U.S. Distributor: United Artists
Forever remembered as the "Japanese Bond", YOU ONLY LIVE TWICE takes 007 to the Far East for his fifth screen adventure, Sean Connery's final consecutive appearance as the top British agent (the actor returned to the role twice more: 1971's DIAMONDS ARE FOREVER and 1983's NEVER SAY NEVER AGAIN). Unfortunately, this is also among the weakest of the early Bond films, although Connery is in peak form.
The plot is the problem. It stretches the limits of credibility, even as that word is applied to Bond movies. Blofeld (Donald Pleasence in his pre-HALLOWEEN days) and SPECTRE hijack American and Soviet spaceships in an attempt to precipitate a war between the superpowers. It's up to Bond to uncover evidence that will avert the conflagration, and the trail leads to Japan. There, he's matched up with the ever- efficient, beautiful Aki (Akiko Wakabayashi) and her boss, Tiger Tanaka (Tetsuro Tamba), as he sets out to find SPECTRE's hideout, and the space capsules concealed there.
The first half of YOU ONLY LIVE TWICE is very good, with several skillfully-executed action sequences and the development of an unexpectedly warm relationship between Bond and Aki. It's only during the second half, as the plot escalates beyond the bounds of preposterousness, that the film starts to fragment. Some viewers enjoy 007's most outrageous outings; I prefer a little restraint (and I emphasize the "a little" part). Wild chases, neat gadgets, and death- defying escapes are fine; rockets that swallow up spacecraft are a bit too extravagant.
The unmasking of Blofeld is a disappointment. In FROM RUSSIA WITH LOVE and THUNDERBALL, he was just an ominous voice, his face carefully hidden from our view. Here, he's seen for the first time, and it's a letdown when all we get is a rather ordinary-looking Donald Pleasance -- a solid actor, to be sure, but not very good at creating a diabolical personality. (The best Blofeld was Max Von Sydow in NEVER SAY NEVER AGAIN.)
Nevertheless, any Bond movie with Sean Connery can't be all bad, and there are the usual chases, fights, and amazing stunts -- all sprinkled with a dash of Japanese flavoring. Bond learns what it means to be a ninja, and gets an opportunity to put that knowledge to use as he zigs and zags, avoiding assassination attempts. Then there's the usual assortment of women, both European and Asian, for Britain's most dashing secret service agent to romance. In short, while YOU ONLY LIVE TWICE falls somewhere in the middle of the 007 film heap, it still offers that unique brand of wit, style, and adventure that only comes with Bond.

Cannabis |
(plant material) |
I first tried marijuana in the winter of my eighteenth year. Until the weeks preceding my first hit, I had viewed marijuana as a dangerous drug used by good-for-nothings too ignorant to foresee the brain damage they would soon sustain. A friend of mine assured me my beliefs were flawed, that in truth marijuana was not nearly as harmful as propagandists made it out to be. I did not believe him, in fact, I decided to research the drug and show him the true extent of his misconception.
To my surprise, the more I learned about marijuana, the more I realized how I, not my friend, had been mistaken. This was no evil, deadly drug, to the contrary, it was a benevolent, even medicinal, plant. Soon I found my curiosity deeply engaged. After a few days of extensive research, I came to a conclusion: I wanted to smoke marijuana and experience its effects firsthand.
Several of my good friends, who had just recently become acquainted with the drug themselves, were overjoyed at my decision. One evening, three of my closest companions and I got together with plans to get high. I have to smile when I look back on my first time smoking grass. There I was, crouched down in a ditch at the end of a deserted cul-de-sac, huddling close with my buddies and trying to keep my hands from freezing while I fumbled with the only lighter we had available: an oversized grill igniter. None of us owned a pipe, so we used a makeshift piece crafted from aluminum foil. We had only a small quantity of bud, so, after holding a hit in for as long as we could, we would blow the smoke into the mouth of the person squatting beside us, and that person would in turn keep the smoke in for as long as possible. It was a slow and economical process, but eventually we depleted the nugget and headed back to the car.
As is often the case with new users, I did not experience a high the first time I smoked. Though I was disappointed, especially when I witnessed my friends’ obvious euphoria, I became all the more determined to get high the next time I lit up. And, not many days later, I did.
The second time I smoked and the first time I got high, I was under a bridge in a relatively deserted part of my hometown. The same three companions that had introduced me to the substance were present again, as were at least three others. The night was cold, and soon after we had finished passing the chillum we began heading back to our vehicles. Then the THC kicked in.
My vision changed, a nearby pile of stones suddenly appeared much more distant than it really was, and the ground was either too close or too far away. At this point, I knew I was high. With that blissful realization came a desire to experience everything I could in this altered state. I jumped up and down, I twirled about, and I ran, taking in these new sensations all at once. The air felt cleaner, clearer. I was no longer as cold as I had been a few minutes earlier. As our group approached the cars, there was a definitive unity in our midst.
Earlier that evening, an experienced friend of mine had told me that driving high was nothing like driving drunk, that I would be able to manage it without any problems. He was correct, but now I realize I was foolish to take his word for it.
[Erowid Note: Driving while intoxicated or tripping is dangerous and irresponsible because it endangers other people. Don't do it!] Though my friends and I were only headed a couple of minutes up the street, I should have been more prudent, what I was about to do was not safe.
As I drove up the road, I was amazed at the dotted white lines moving towards me. I pulled into a local gas station, a pit stop my friends and I had previously agreed upon to satisfy—it felt good to think it—“the munchies.” Inside, I did my best to maintain composure, but this new chemical in my body was too powerful. I caught a glimpse of one of my companions at the end of an aisle and burst out laughing. Somehow, I managed to purchase some snacks and walk back outside. Out in the parking lot, I froze. There, only a couple of parking spaces away from my vehicle, was a police cruiser.
Paranoia set in. After a moment’s hesitation, I approached my car, making every effort to remain calm. Of course, there was probably nothing suspicious about an average-looking young man walking out of a gas station, but the paranoia whispered things like, It’s hopeless, that officer knows you smoked marijuana, and he’s going to arrest you. Your parents will find out, and your life will be ruined. Fortunately, nothing of the sort happened. My anxiety did increase, however, when one of my friends came skipping out of the gas station, singing or whistling or some nonsense like that. At that point I was almost positive that the officer would question us about my friend’s strange behavior, but in reality I don’t think he even noticed us. When we pulled into my friend’s driveway, I felt a great deal of relief. Naturally, being at ease greatly increased the enjoyment of my high, and from the moment I stepped out of the car, my symptoms began to intensify.
First, right after he stepped out of the car, one of my friends faces became almost invisible. I was actually unable to recognize him for a few seconds, and when I finally could, I started to laugh at the playfulness and absurdity of it all. Once inside, we slipped by my friend’s parents and shuffled down into the basement, where we dimmed the lights and put on some tunes. I still remember the first song I ever listened to high: Finley Quaye’s “Even after All.” It was an incredible treat for my ears.  I recall sitting Indian-style on the floor, zoning out and staring at a stereo speaker for several minutes.  Everything was fascinating, everything was funny, everything was sweet.
That cold night in January I developed a true appreciation for cannabis sativa, an appreciation that has only grown with time and that I maintain to this day.

Mariano Martinez Peck<EMAIL_ADDRESS>/ [https://marianopeck.wordpress.com/](https://marianopeck.wordpress.com/))
Abstract: Anyone that has ever done a deployment with Smalltalk knows how easy it can be compared to other languages. But the technology space is always in motion and with a continued increase in DevOps roles, the rest of the world offers top notch technologies for improving deployment, availability, scalability, and other aspects of the whole software engineering process.
In this talk, I will show how VA Smalltalk integrates smoothly with these technologies to build enterprise-class scalable and performant systems. I will demonstrate how to take an application from the development environment and prepare it for deployment. I will show how to get started with Docker by building Docker images and running them within isolated containers. Finally, I will create an ARM 64 cluster using Raspberry Pi and a Pine64 IoT devices that will be running a cloud of containers: a Docker Swarm.
Bio: Mariano is a systems engineer specializing in software solutions based on dynamic programming languages currently working at Instantiations Inc. He contributes to the development and maintenance of VA Smalltalk commercial development environment. Responsibilities include crafting or importing frameworks, libraries and tools, as well as improving the existing code base of the product.
As a Smalltalk expert, he is active in the Smalltalk community and has co-authored numerous open-source project. Mariano’s academic research has been published across various international journals. He has a PhD in Computer Science from RMOD-INRIA and the École Des Mines de Douai in France, where his thesis was on application-level virtual memory for object-oriented systems.

5 Steps to Achieving Inbox Zero
If you have more than twenty emails in your inbox right now you may need to research methods on how to manage your email. Inbox Zero is a way of life that promotes a clean and empty email inbox at all times. Once you check your email, you clean it immediately. Create todo items, scribble in reference items, or reply to people in touch with you as soon as you see an email.
Getting started isn’t easy and can be a daunting task. These 5 steps will help break down the process and hopefully mitigate the torture of making big changes to your chaotic inbox.
1. Get the right email app
Inbox Zero is a methodology that can technically be used with any software but that doesn’t mean it isn’t easier and encouraged by certain apps and services. Basic email apps like Gmail, ’s standard Mail.app, and other generic email clients are some of the most bare-boned ways to manage email. Some people may like the lack of fluff — or in Apple’s case, the addition of their machine learning and sketching features. Ugly and primitive email clients can be great for staying focused on what really matters.
Email clients that encourage Inbox Zero make it very obvious and are difficult to use any other way. Apps like Airmail, Inbox by Gmail, and Outlook all have distinct features that make you want to have an empty inbox.
Conveniences like snoozing email to a later date, bundling promos and updates into folders automatically, and displaying animations when you reach Inbox Zero are great ways to accomplish effectively managed email.  Being reminded about an email you send out a month later if there’s no response is surely a job the email client can handle without you cluttering your todo list with outreach tasks like that. Although they’re not essential, they’re great to have.
2. Create folders
You don’t keep all your documents, photos, programs, and links on your desktop — I hope you don’t. You probably have a documents directory with subdirectories and even folders inside that to categorize your Photoshop files along with your wedding photos and all separated from your essays you need for school.
Managing email as files is a great way to think of how to store them when they act as reference items or reminders. Creating folders in your email client for things like "waiting", "reference", and "family vacation" bring so much value to your workflow. Search functionality in email clients are great nowadays but there’s no better feeling than opening up your email client, navigating to a folder, and instantly finding the confirmation number for the musical tickets you’re bringing a friend to while waiting on line.
3. Archive everything
The most action you’re ever going to take regarding your email is when you finally decide to archive everything. If you’re like most people, you keep hundreds of emails in your inbox and "mark as read" the ones you want to forget about without actually allocating them someplace or deleting them. This probably means you have tens, hundreds, or even thousands of emails all in one place and always in your face.
Archiving is the safest thing you can do with an email. Nothing is getting deleted and everything is still searchable. You’re merely getting it out of your face and not being bothered with it until that one time every few years you find yourself making obscure search queries to find an old email again.
The recommended method of going about this is simply selecting all and archiving it. You’ll feel better, sleep better, and live longer.
4. Hew to the Inbox Zero mindset
Now that your environment is built you have to modify some behavior to maintain it. I never leave people with a beautiful system just to ditch them and have them mess it up a week later. There’s a mindset that has to be learned and adhered to.
In short - understand the Inbox Zero workflow by checking your email at certain and scheduled times of the day, taking action on all emails immediately whether you’re replying on the spot, deferring it to a later date, archiving it on the spot, or creating action items based on it that you have to take care of later. Your inbox is for getting mail, not storing nor prioritizing them.
5. Use your trusted system
The most effective way of managing your email is to not manage it at all. If you have a trusted task manager all your email can flow directly into it. Any new mail can act as an action item — something has to be done with this; it may be as simple as recording it in the journal or as complicated as writing a four-page proposal for a new customer. No matter what has to be done with it, it’s better if it’s managed in your trusted system than in your inbox. If your inbox is your only trusted system, that calls for some further thought and action into your system.
Email is the best and worst thing in the world. Inbox Zero makes it slightly less terrible. Taking action on these steps and learning the ways of a well-managed and effective email will make you a more productive and happier person.

--- layout: post title: switch logfile VS archive log current date: 2008-07-16 20:09:05.000000000 +09:30 type: post published: true status: publish categories: - Oracle tags: - study - log - oracle meta: posturl_add_url: 'yes' _edit_last: '1' views: '751' ---
oracle文档这样解释
The SWITCH
LOGFILE
clause lets you explicitly force Oracle to begin writing to a new redo log file group, regardless of whether the files in the current redo log file group are full. When you force a log switch, Oracle begins to perform a checkpoint but returns control to you immediately rather than when the checkpoint is complete. To use this clause, your instance must have the database open.
Specify CURRENT
to manually archive the current redo log file group of the specified thread, forcing a log switch. If you omit the THREAD
parameter, then Oracle archives all redo log file groups from all enabled threads, including logs previous to current logs. You can specify CURRENT
only when the database is open.
Specify NOSWITCH
if you want to manually archive the current redo log file group without forcing a log switch. This setting is used primarily with standby databases to prevent data divergence when the primary database shuts down. Divergence implies the possibility of data loss in case of primary database failure.
You can use the NOSWITCH
clause only when your instance has the database mounted but not open. If the database is open, then this operation closes the database automatically.  checkpoint过程和归档过程之间没有依赖性。
当上面lwgr触发的checkpoint 过程完成后，会将日志文件的状态从active转到inactive; 这时候这个日志文件才可以被重新写。也就说 并不是日志文件被归档后就可以被覆盖。而要等待发生在该日志文件的检查点过程结束。
如果lgwr要覆盖一个其上检查点过程没有结束的日志文件，lgwr会等待dbwr完成，且应用session会hang住；在alter.log文件中 会出现，checkpoint not complete,unable to allocate new redo log file 类似的错误
当然，如果这个时候db不是自动归档，那么发出switch logfile之后，只会触发ckpt,arc进程不会触发，要使得redo归档，必须手工发出alter system archive log current

THE MAGPIE.
"ONE is asign of anger, Two is a sign of mirth, Three is a sign of a wedding, Four is a sign of a birth/death."
A scolding woman is called a magpie. Whenever you see a magpie, take off your hat to it; this will turnaway the anger.


I recently came across a State of the Art (SOTA) problem according to me. How I define a problem to be really good-
I do not claim that the problem has been made by me in any manner. I found this question while attempting Google FooBar.
Someone who you earlier worked for has sent her elite fighter pilot squadron after you - and they’ve opened fire!
Fortunately, you know something important about the ships trying to shoot you down. Back when you were still her assistant, she asked you to help program the aiming mechanisms for the ships. They undergo rigorous testing procedures, but you were still able to slip in a subtle bug. The software works as a time step simulation: if it is tracking a target that is accelerating away at degrees, the software will consider the targets acceleration to be equal to the , adding the calculated result to the targets end velocity at each timestep. However, thanks to your bug, instead of storing the result with proper precision, it will be truncated to an integer before adding the new velocity to your current position. This means that instead of having your correct position, the targeting software will erringly report your position as-
not far enough off to fail her testing, but enough that it might just save your life.
If you can quickly calculate the target of the starfighters’ laser beams to know how far off they’ll be, you can trick them into shooting an asteroid, releasing dust, and concealing the rest of your escape. Write a function which, given the string representation of an integer , returns the sum of
as a string. That is, for every number in the range to , it adds up all of the integer portions of .
For example, if was , the solution would be calculated as-
so the function would return
can have values upto which means it can have numbers with 101 digits! Try solving this problem yourself first before heading to the solution.
PS: If it was as easy as a for loop I would not have written this in the first place
This seems like a very easy problem. If you remove the story line, all you need to calculate is-
The only twist is you cant use recursion for each element or use a for loop as the numbers are too big. You need to try and simplify the expression.
Just some convention-
This type of sequence is called a Beatty sequence. Beatty sequence is the sequence of integers
found by taking the floor of the positive multiples of a positive irrational number. However, you do
not require any knowledge of it to solve the problem.
Let’s define a function for some irrational number and
if we say and we can also say-
Also, if and then sequences and for partition
So,
And also
Then, letting we have
Back to the problem, we have , so we start with . We can get a recurrence formula. Let
And we solved the problem, got an optimal way to solve it :)
Let us now take a look at implementing this in code. We will just convert all what we just talked about to code.

IGit is a tool for managing pull requests. It works with GitHub's API and provides mechanisms for keeping you in the loop.  IGit will give you the feel of control because it shows you exactly what's new.
IGit is open source. If you like it please give it a star or share it in Twitter.
Star TweetThat was always an issue for me. I am working actively on three repositories and have to changes pages all the time. If not that I have to keep bunch of tabs open which is a little bit frustrated for a person that loves to have just a few opened.
I bet it happens to you every day - you open a pull request, you review it and then some changes comes in. You have to again scan the PR, the comments and the new commits to understand what is actually new. IGit remembers what you checked and compares it to the incoming events. Then it sets a red marker on the new stuff. You are free to leave them unseen which I'm very often doing as a reminder that I have some work to do.
Although there are bunch of things which I'm missing in GitHub's UI it still provides some slick interaction patterns. I mimic most of them here in IGit.

java.lang.Object java.util.Timer
public class Timer
A facility for threads to schedule tasks for future execution in a background thread. Tasks may be scheduled for one-time execution, or for repeated execution at regular intervals.
Corresponding to each Timer object is a single background thread that is used to execute all of the timer's tasks, sequentially. Timer tasks should complete quickly. If a timer task takes excessive time to complete, it "hogs" the timer's task execution thread. This can, in turn, delay the execution of subsequent tasks, which may "bunch up" and execute in rapid succession when (and if) the offending task finally completes.
After the last live reference to a Timer object goes away and all outstanding tasks have completed execution, the timer's task execution thread terminates gracefully (and becomes subject to garbage collection). However, this can take arbitrarily long to occur. By default, the task execution thread does not run as a daemon thread, so it is capable of keeping an application from terminating. If a caller wants to terminate a timer's task execution thread rapidly, the caller should invoke the timer's cancel method.
If the timer's task execution thread terminates unexpectedly, for example, because its stop method is invoked, any further attempt to schedule a task on the timer will result in an IllegalStateException, as if the timer's cancel method had been invoked.
This class is thread-safe: multiple threads can share a single Timer object without the need for external synchronization.
This class does not offer real-time guarantees: it schedules tasks using the Object.wait(long) method.
Implementation note: This class scales to large numbers of concurrently scheduled tasks (thousands should present no problem). Internally, it uses a binary heap to represent its task queue, so the cost to schedule a task is O(log n), where n is the number of concurrently scheduled tasks.
Implementation note: All constructors start a timer thread.

In fixed-delay execution, each execution is scheduled relative to the actual execution time of the previous execution. If an execution is delayed for any reason (such as garbage collection or other background activity), subsequent executions will be delayed as well. In the long run, the frequency of execution will generally be slightly lower than the reciprocal of the specified period (assuming the system clock underlying Object.wait(long) is accurate).
Fixed-delay execution is appropriate for recurring activities that require "smoothness." In other words, it is appropriate for activities where it is more important to keep the frequency accurate in the short run than in the long run. This includes most animation tasks, such as blinking a cursor at regular intervals. It also includes tasks wherein regular activity is performed in response to human input, such as automatically repeating a character as long as a key is held down.

IllegalStateException
- if task was already scheduled or

In fixed-rate execution, each execution is scheduled relative to the scheduled execution time of the initial execution. If an execution is delayed for any reason (such as garbage collection or other background activity), two or more executions will occur in rapid succession to "catch up." In the long run, the frequency of execution will be exactly the reciprocal of the specified period (assuming the system clock underlying Object.wait(long) is accurate).
Fixed-rate execution is appropriate for recurring activities that are sensitive to absolute time, such as ringing a chime every hour on the hour, or running scheduled maintenance every day at a particular time. It is also appropriate for recurring activities where the total time to perform a fixed number of executions is important, such as a countdown timer that ticks once every second for ten seconds. Finally, fixed-rate execution is appropriate for scheduling multiple repeating timer tasks that must remain synchronized with respect to one another.

Note that calling this method from within the run method of a timer task that was invoked by this timer absolutely guarantees that the ongoing task execution is the last task execution that will ever be performed by this timer.
This method may be called repeatedly; the second and subsequent calls have no effect.
public int purge()
Most programs will have no need to call this method. It is designed for use by the rare application that cancels a large number of tasks. Calling this method trades time for space: the runtime of the method may be proportional to n + c log n, where n is the number of tasks in the queue and c is the number of cancelled tasks.
Note that it is permissible to call this method from within a a task scheduled on this timer.

Factory Bot is a helper for writing factories for Ruby tests. It was previously known as Factory Girl. For older versions, use FactoryGirl
instead of FactoryBot
.
FactoryBot.define do
factory :user do
first_name { 'John' }
last_name { 'Doe' }
birthdate { 21.years.ago }
admin { false }
sequence(:username) { |n| "user#{n}" }
end
end

See: Defining factories
build(:user) # → model (not saved)
create(:user) # → model (saved)
attributes_for(:user) # → hash
build_stubbed(:user) # stubbed out attributes
factory :post do
association :author, factory: :user
association :author, factory: [:user, :admin]
end
{: data-line=“2,3”}
factory :post do

osc-js
osc-js is an Open Sound Control library for all your JavaScript applications (UMD module for Node, Browser etc.) with address pattern matching and timetag handling. Sends messages via UDP, WebSocket or both (bridge mode) and offers a highly customizable Plugin API for your own network solutions.
Wiki | Basic Usage | ESDoc Documentation | Plugin API
Features
- UMD Module running in Node.js, Electron, Chrome Apps, your browser or any other JS environment
- can be used with Webpack and Browserify
- no dependencies (except of
ws
in Node.js or similar environments) - simple interface
- built-in UDP, WebSocket networking support as plugins
- special bridge plugin for easy communication between UDP- and WebSocket clients
- Plugin API for your own custom networking solutions
- featuring all OSC 1.0 specifications
- OSC Address pattern matching
- time-critical OSC Bundles with Timetags
- osc-js is written in ES6 :-)
Documentation
Read more about osc-js and how to use it in the Wiki.
Example
const osc = new OSC()
osc.on('/param/density', (message) => {
console.log(message.args)
})
osc.on(['param', 'volume'], (message) => {
console.log(message.args)
})
osc.on('open', () => {
const message = new OSC.Message('/test', 12.221, 'hello')
osc.send(message)
const bundle = new OSC.Bundle(Date.now() + 5000)
bundle.add(message)
osc.send(bundle, { host: '<IP_ADDRESS>' })
})
osc.open({ port: 9000 })
Installation and Usage
Recommended installation via bower bower install osc-js --save
or npm npm install osc-js --save
.
Import the library const OSC = require('osc-js')
or add the script dist/osc.js
or dist/osc.min.js
(minified version) for usage in a browser.
To build the library with Webpack or similar tools without errors, use the alias
configuration and point the module to node_modules/osc-js/lib/osc.browser.js
. Read more about bundling issues here: Webpack Bundling.
Plugins
osc-js offers a plugin architecture for extending it's networking capabilities. The library comes already with four built-in plugins. This is propably all you will ever need for your OSC applications:
WebsocketClientPlugin
(default)WebsocketServerPlugin
DatagramPlugin
for UDP network messagingBridgePlugin
useful Bridge between WebSocket- and UDP Clients
Configuration and examples of every plugin can be read here: Wiki.
Example: WebSocket Server
Register the plugin when creating the OSC instance:
const osc = new OSC({ plugin: new OSC.WebsocketServerPlugin() })
osc.open() // listening on 'ws://localhost:8080'
Example: OSC between MaxMSP/PD/SC etc. and your browser
Write a simple webpage. The library will use a WebSocket client by default.
<button id="send">Send Message</button> <script type="text/javascript" src="dist/osc.min.js"></script> <script type="text/javascript"> var osc = new OSC(); osc.open(); // connect by default to ws://localhost:8080 document.getElementById('send').addEventListener('click', function() { var message = new OSC.Message('/test/random', Math.random()); osc.send(message); }); </script>
Write a Node app (the "bridge" between your UDP and WebSocket clients).
const OSC = require('osc-js') const config = { udpClient: { port: 9129 } } const osc = new OSC({ plugin: new OSC.BridgePlugin(config) }) osc.open() // start a WebSocket server on port 8080
Create your Max/MSP patch (or PD, or SuperCollider or whatever you need).
[udpreceive 9129] // incoming '/test/random' messages with random number
Custom solutions with Plugin API
It is possible to write even more sophisticated solutions for your OSC application without loosing the simple osc-js interface (including it's nice message handling etc.). Read the Plugin API documentation for further information.
class MyCustomPlugin {
// ... read docs for implementation details
}
const osc = new OSC({ plugin: MyCustomPlugin() })
osc.open()
osc.on('/test', (message) => {
// use event listener with your plugin
})
Usage without plugins
The library can also be used without the mentioned features in case you need to write and read binary OSC data. See this example below for using the Low-Level API (even though the library already has a solution for handling UDP like in this example):
const dgram = require('dgram')
const OSC = require('osc-js')
const socket = dgram.createSocket('udp4')
// send a messsage via udp
const message = new OSC.Message('/some/path', 21)
const binary = message.pack()
socket.send(new Buffer(binary), 0, binary.byteLength, 41234, 'localhost')
// receive a message via UDP
socket.on('message', (data) => {
const msg = new OSC.Message()
msg.unpack(data)
console.log(msg.args)
})
Development
osc-js uses Babel for ES6 support, ESDoc for documentation, Mocha + Chai for testing and Rollup for generating the UMD module.
Clone the repository and install all dependencies:
git clone git@github.com:adzialocha/osc-js.git
cd osc-js
npm install
Testing
npm run test
for running the test suites.
npm run test:watch
for running specs during development. Check your style guide violations with npm run lint
.
Deployment
npm run build
for creating a UMD module in lib
folder and a browser distribution in dist
folder.

School's Message: ICA is an all-girls school in San Francisco California’s Mission District. We are extremely appalled by all of the horrific events that have taken place recently due to poor gun control laws and people in government willingly disregarding the tragic shootings that have taken place in schools. Schools should house environments of learning and fun, not violence. Together, we implore Nancy Pelosi to endorse stricter gun control. We understand that the process towards harsher gun control will be a cumbersome one, but this is a pivotal issue that must be tackled.

This issue needs to be addressed!!!
Wow this happened in my city too!!!

We'd love to accept your patches! Before we can take them, we have to jump a couple of legal hurdles.
Please fill out either the individual or corporate Contributor License Agreement (CLA).
Follow either of the two links above to access the appropriate CLA and instructions for how to sign and return it. Once we receive it, we'll be able to accept your pull requests.
If you are a Googler, please make an attempt to submit an internal change rather than a GitHub Pull Request. If you are not able to submit an internal change a PR is acceptable as an alternative.
The Google Test community exists primarily through the discussion group and the GitHub repository. Likewise, the Google Mock community exists primarily through their own discussion group. You are definitely encouraged to contribute to the discussion and you can also help us to keep the effectiveness of the group high by following and promoting the guidelines listed here.
Showing courtesy and respect to others is a vital part of the Google culture, and we strongly encourage everyone participating in Google Test development to join us in accepting nothing less. Of course, being courteous is not the same as failing to constructively disagree with each other, but it does mean that we should be respectful of each other when enumerating the 42 technical reasons that a particular proposal may not be the best choice. There's never a reason to be antagonistic or dismissive toward anyone who is sincerely trying to contribute to a discussion.
Sure, C++ testing is serious business and all that, but it's also a lot of fun. Let's keep it that way. Let's strive to be one of the friendliest communities in all of open source.
As always, discuss Google Test in the official GoogleTest discussion group. You don't have to actually submit code in order to sign up.
To keep the source consistent, readable, diffable and easy to merge, we use a fairly rigid coding style, as defined by the google-styleguide project. All patches will be expected to conform to the style outlined here. Use .clang-format to check your formatting.
If you plan to contribute a patch, you need to build Google Test, Google Mock, and their own tests from a git checkout, which has further requirements:
This section discusses how to make your own changes to the Google Test project.
To make sure your changes work as intended and don't break existing functionality, you'll want to compile and run Google Test and GoogleMock's own tests. For that you can use CMake:
mkdir mybuild cd mybuild cmake -Dgtest_build_tests=ON -Dgmock_build_tests=ON ${GTEST_REPO_DIR}
To choose between building only Google Test or Google Mock, you may modify your cmake command to be one of each
cmake -Dgtest_build_tests=ON ${GTEST_DIR} # sets up Google Test tests cmake -Dgmock_build_tests=ON ${GMOCK_DIR} # sets up Google Mock tests
Make sure you have Python installed, as some of Google Test's tests are written in Python. If the cmake command complains about not being able to find Python (Could NOT find PythonInterp (missing: PYTHON_EXECUTABLE)
), try telling it explicitly where your Python executable can be found:
cmake -DPYTHON_EXECUTABLE=path/to/python ...
