Network Saboteur
问题描述 :
A university network is composed of N computers. System administrators gathered information on the traffic between nodes, and carefully divided the network into two subnetworks in order to minimize traffic between parts.
A disgruntled computer science student Vasya, after being expelled from the university, decided to have his revenge. He hacked into the university network and decided to reassign computers to maximize the traffic between two subnetworks.
Unfortunately, he found that calculating such worst subdivision is one of those problems he, being a student, failed to solve. So he asks you, a more successful CS student, to help him.
The traffic data are given in the form of matrix C, where Cij is the amount of data sent between ith and jth nodes (Cij = Cji, Cii = 0). The goal is to divide the network nodes into the two disjointed subsets A and B so as to maximize the sum ∑Cij (i∈A,j∈B).

输出规范写错了哦~
第一种方法怎么会是O(log(m+n))呢？没有二分的话直接遍历应该就是O(m+n)吧？
位运算真赞
mark, 备用
真心不错，力顶作者
给力的文章，例子也非常好
想问下computeLSPArray那里，if(len!=0) len=lps[len-1]是什么意思
int half(int *array,int len,int key)
{
int l=0,r=len;
while(l<r)
{
int m=(l+r)>>1;
if(key>array )l=m+1;
else if(key<array )r=m;
else return m;
}
return -1;
}
这种就能避免一些Bug
l,m,r
左边是l,m;右边就是m+1,r;
秒！~

SitaraWare Overview
SitaraWare provides no-OS platform support for Sitara family of processors on the Texas Instruments recommended Sitara EVMs. SitaraWare provides Device Abstraction Layer libraries and peripheral/board level sample/demo examples that demonstrate the capabilities of the peripherals on the Sitara processors. This package includes the following components:
NOTE
Though SitaraWare is intended to support multiple processors
of the Sitara family, support may be in a phased manner. The supported list of
processors and the assosciated device abstraction layer of the peripherals as
part of the library is mentioned in the release notes for every release.
- Device Abstraction Layer Library. This contains device abstraction layer for supported peripherals. The included object files are built with Sourcery G++ Lite 2009q1-161 for ARM-NONE-EABI from CodeSourcery.
- Peripheral Examples. This contains the sample applications which shall demonstrate some of the capabilities of the peripheral by using the Device Abstraction Layer APIs. The executables of the sample applications included with this release is built with Sourcery G++ Lite 2009q1-161 for ARM-NONE-EABI from CodeSourcery
- System Configuration code. This contains the primary code that sets up the Sitara processor core and prepares the system for execution of the sample application.
- Platform Code. This contains the EVM specific initialization code. This code sets up the EVM specifics like pinmux, IO expanders, GPIOs and similar board specific stuff that shall enable proper exucution of the applications.

- drivers - This directory contains the source files for the driver library APIs and build files for the driver library. The build directory contains compiler/tools specific directories which hold the related files. For example, the makefiles for the GCC are under gcc directory. Once build, the library/archive is placed in a tool specific directory under drivers/. For example, when make is invoked from driver/buils/gcc, the driverlib.a is placed as drivers/gcc/driverlib.a
- examples - Examples provided as part of the package showcase some 9not all) functionality of the peripheral. This depends on the availability of a peripheral instance and its association, mux settings etc on the EVM. Thus examples differ between EVMs, and thus are classified at the top level based the EVMs that there are intended to run. Each example contains a src/ directory which contains the source files and a build/ directory containing the build files. The build files are grouped based on the tools/compiler. For example, ccs/ shall contain the Code Composer Studio (CCS) project files and gcc shall only contain the make file. Note that, only the applications are supplied with a CCS project for aiding in loading and debugging applications. The library build files are internally invoked by the application build files. The generated binary/executable is placed in toll specific directory under the example. For example, uart.out is placed under uart/gcc/uart.out
- include - The header files for inclusion are all placed under
include/. The include files are classified as,
1. user interface driver headers, for example uart.h, which contain macro definitions and prototypes for the functions which a user might need to use for programming.
2. SOC or EVM specific header files which contain SOC specfic information/definitions, for example interrupts, CPU operations or definitions.
3. Peripheral register level definitions like register offsets and macros. - platform - Every supported EVM is called as a (hardware) platform inside the package. This exports functions specfic to an EVM that usually do (as required) peripheral mux settings, EVM mux/IO expander settings etc, to enable a peripheral operation on the platform. This code is separated out of the main applications/examples to provide a simpler look at the first level.
- system_config - The system configuration and setup code, like stratup code, interrupt vector initialization, low level CPU specific code etc are provided here. Since, this may involve assmebly level coding, such code is placed under tools specific directory.
- bootloader - Contains the boot loader specific files. The make file for building bootloader can be found in build/gcc/ folder. The bootloader executable boot.out file can be found in /gcc folder.
- third_party - May contain software from third party used, if any.
- tools - May contain tools used, if any.
- utils - May contain utility scripts etc used, if any.
Host platform Requirements
Building and runnning SitaraWare applications can be from a Windows machine or a Linux machine
A host machine is required only for:
- Compiling the SitaraWare applications
- Launching CCS v5 and loading and runnning the applications on the Sitara target
Host Software Requirements
- Code Composer Studio version CCS <IP_ADDRESS>81 for Linux and/or Windows (needed for (re)building and/or loading and running applications on the target/EVM)
- CodeSourcery tool chain for ARM : Sourcery G++ Lite 2009q1-161 for ARM-NONE-EABI for Linux and/or Windows
- Cygwin (for Windows host only) to facilitate GCC build
- Serial console terminal application (like Teraterm, minicom, HyperTerminal)
Getting Started Quickly
The SitaraWare package contains pre-compiled peripheral level examples that can be run on the EVM. Steps to run the examples are detailed here in:
Creating a target configuration, if one doesn't exist already.
- Launch Code Composer Studio v5 eclipse IDE
- File menu-> New-> Other-> General ->Target Configuration File. Click Next
- Filename : AM1808EVM. Check "Use shared location" to be available to anyone who uses the workspace. Click Finish. A window opens up which is to configure the connection details
- Connection: Chose the host-to-target connection details. For example "Spectrum Digital XDC510 USB Emulator", if XDS510 is being used.
- Device: Type AM1808. AM1808 should be available in the device list. Select AM1808
- Click on "Target Configration". "Initialization Script" should point to a proper GEL file that needs to be used.
- Click Save.
Launching a debug session and connecting to the target
- Run Menu ->Debug. This will launch the debugging session for AM1808
- Right Click on the ARM9 target and select Connect.
Loading and running a program/executable
- Run menu ->Load ->Load Program. Here browse to the required exeuctable and click OK
- Run menu -> Run
Building application - CCS project
SitaraWare package also contains the build files and CCS project files to enable the user to rebuild any modifications. The CCS project files enable those users who are comfortable with building the projects rather than command line invocation of make file. CCS projects are provided only for applications, which internally invoke the make files.
- Make changes to the source files and edit the makefiles accordingly
- Launch Code Composer Studio v5 eclipse IDE
- File menu-> Import-> CCS-> Existing CCS/CCE Eclipse Projects
- Select search-directory . Here, browse to the required example directory and click OK. A list of available projects will be displayed.
- Check only the example that is intended and click finish
- Project Menu-> Build All. This will build the selected project
Building application - Command line
From the shell window, change to the application build directory and type "make clean; make"
NOTE
1. In both cases of building the application, as detailed
above, the library makefiles are are internally invoked.
2. If a Windows
host is used, then cygwin needs to be installed.
3. Ensure that the PATH
envirinment variable contains the path for the compiler/tool chain.
4. When
compiling via CCSv5, ensure that the environment for each build configuration
(Cygwin and Linux) of the project the follwoing variable(s) are set:
LIB_PATH points to the Code Sourcery installation: Ex:
LIB_PATH=/opt/tools/CodeSourcery/Sourcery_G++_Lite/
5. When compiling via
command line, ensure that the following variable is exported :
export
LIB_PATH=/opt/tools/CodeSourcery/Sourcery_G++_Lite/
6. If Cygwin is to be
used, ensure that the code sourcery installation path does not contain any white
space.


General
Legacy DistCp works by figuring out what files need to be actually copied to target before the copy-job is launched, and then launching as many maps as required for copy. So if a majority of the files need to be skipped (because they already exist, for example), fewer maps will be needed. As a consequence, the time spent in setup (i.e. before the M/R job) is higher.
The new DistCp calculates only the contents of the source-paths. It doesn't try to filter out what files can be skipped. That decision is put- off till the M/R job runs. This is much faster (vis-a-vis execution-time), but the number of maps launched will be as specified in the -m option, or 20 (default) if unspecified.
At present, the smallest unit of work for DistCp is a file. i.e., a file is processed by only one map. Increasing the number of maps to a value exceeding the number of files would yield no performance benefit. The number of maps lauched would equal the number of files.
If the number of individual files/directories being copied from the source path(s) is extremely large (e.g. 1,000,000 paths), DistCp might run out of memory while determining the list of paths for copy. This is not unique to the new DistCp implementation.
To get around this, consider changing the -Xmx JVM heap-size parameters, as follows:
bash$ export HADOOP_CLIENT_OPTS="-Xms64m -Xmx1024m"
bash$ hadoop distcp /source /target

THE PATRIOT
Reviewed by Harvey Karten Columbia Pictures/Centropolis Director: Roland Emmerich Writer: Robert Rodat Cast: Mel Gibson, Heath Ledger, Joely Richardson, Jason Isaacs, Trevor Morgan, Bryan Chafin, Skye McCole Bartusiak, Beatrice Bush, Rene Auberjonois, Donal Logue, Logan Lerman, Michael Neeley, Chris Cooper, Tcheky Karyo,
When Playboy magazine critic Leonard Maltin slammed Hugh Hudson's 1985 movie about the American War for Independence, "Revolution," he predicted that "thanks to this megabomb, it'll be 2776 until we get another one." Though critics are never wrong, this is the exception. "Revolution," one of only about a half-dozen films that deal seriously with the Eighteenth-Century conflict, featured top actors Al Pacino, Donald Sutherland, Natassja Kinski and Joan Plowright. Nonetheless, Maltin called the script ludicrous and the acting a travesty. Unless you get a chance to take in D.W. Griffith's 1924 silent, "America," with Lionel Barrymore in an especially villainous role, "The Patriot" will likely be your first opportunity to see Redcoats and peasants battle in open fields, their stated mission to prevent the armies of General Cornwallis from moving swiftly North to New York.
While "Gone With the Wind" exploited our fascination with the Civil War during a good deal of the last century, Americans now seem to have lost interest in that conflagration and, indeed, for history in general. What could be more unusual, more horrifying, than the great experiment in modern democracy's pitting brother against brother during the 1860's? And nowadays, who could imagine that Americans could so enthusiastically fight the British people, now our staunchest allies? Perhaps the apathy lies with the history curriculum, which sucks the life out of these events by concentrating on laundry lists of causes and results and the political attitudes of only high government officials.
Utilizing Robert Rodat's ("Saving Private Ryan") screenplay, German director Roland Emmerich presents the rebellion of England's thirteen colonies with a full range of human emotions and ideologies. "The Patriot" examines the theme of father-son conflict, pits the pleas of pacifism against the allure of belligerence, sets the cowardice of collaboration against the mandate of patriotism. Some battle sequences rival even the exceptional panoramas of Steven Spielberg's "Saving Private Ryan." Solid performances by Mel Gibson in the title role and handsome Australian Heath Ledger as his defiant son fashion "The Patriot" as a spectacle that could cause its audience to rise up against the dull treatment of this marvelous episode from history teachers. By fixing attention on the lives of ordinary southerners during the final quarter of the Eighteenth Century, the film at once illuminates the ways that we ourselves might have fared were we living in good old colony times and crosses the border into schmaltz and cutesy-poo sentimentality.
Emmerich opens on a scene with the kind of humorous metaphoric resonance that can be easily grasped by a the broad audience which the picture hopes to attract. Benjamin Martin (Mel Gibson), a French-and-Indian war hero noted for his ability to fight guerrilla style rather than confront the enemy on open grasslands, has retired to raise his seven children as a single parent. Since his wife had died leaving the youngsters largely in the custody of his sister-in-law Charlotte (Joely Richardson), Martin is now determined to lay down his muskets despite the call to arms by his neighbors in the early stages of the Revolution. But when the Redcoats take the fighting right into Martin's back yard, gratuitously shooting one of his sons in the back while taking another to be hanged, Martin can no longer embrace pacifism. Arming his male children, he sets out to free his eldest son, Gabriel (Heath Ledger) and avenge the death of his boy at the hands of the evil Col. William Tavington (Jason Isaacs), whose arrant brutality shocks even the officer's superior and supreme commander of the English forces, General Cornwallis (Tom Wilkinson).
What follows during this two hour and forty-one minutes' epic is a series of scenes, alternately ruthless and emotional, as Emmerich unfolds a microcosm of the war's effect on ordinary American families during the final year of the colonial experience. While critics will be divided on which aspect is the more effective--the scenes of carnage in the fields or the display of family tensions and political strife within the environs of Charleston--I would applaud principally the former. Emmerich's cinematographer, Caleb Deschanel, makes more than effective use of costume designer Deborah L. Scott's uniforms, the outfits contrasting the majestic attire of the English (which ironically increased their vulnerability) with the peasant threads of the irregular fighting forces known as the militia. This was a time that every citizen was armed, when attempts to pass gun control laws would be properly looked upon with laughter by the raggedy bunch of "farmers with pitchforks" whose ability to take on the disciplined armies of Redcoats so shocked Cornwallis. (The right of the people to keep bear arms, "a well-regulated Militia, being necessary to the security of a free State," was to be incorporated into the Constitution fifteen years later and to become one of the most politically charged battlefields in our own time.)
The most memorable scene occurs shortly after the lingering opening of the movie, as Martin hands guns to his kids, who then methodically and with no small butchery ambush and wipe out a force of Redcoats holding Gabriel prisoner. This is the scene bound to be the most talked- about one in the movie, as present-day Americans, horrified by a sequence of murders committed by youngsters in Columbine High School and other institutions of learning, will protest the butchery.
While Martin's struggle with his insubordinate son Gabriel is well-handled--the teenager insisting on his prerogative to sign up for the conflict like any adult--other aspects of family life are maudlin. Emmerich often lingers on the scrubbed faces of the Martin brood, capturing the love-hate feelings of Martin's youngest, Susan (Skye McCole Bartusiak) in the manner of a TV soap while frequently cutting to the other children, Thomas, Williams, Samuel, Nathan and Margaret simply to evoke "awww's" from those in the audience who enjoy expressing their affinity to young'uns. Nor does Emmerich shy away from too obviously suggesting the shy attraction between Martin and Charlotte, with Charlotte at one time pretentiously intoning, "I am not my sister." The family sequence that does stand out involves the mostly New England custom of bundling, in which a young man and his sweetheart are allowed to spend some time alone in bed without undressing. The way the Pennsylvania Dutch do this is to place a wooden board between the lovers, but in the situation at hand, Gabriel is swaddled in a primitive straitjacket to immobilize his arms and legs before he is joined in the sack by his girl friend, while his in-laws-to-be retire to the next room, their ears scrunched tightly to the wall.
The largest flaw in this mostly meritorious project is its predictability.  And how often have we seen the tables turned as antagonists, facing each other, talk instead of shooting, or get tricked as the opponents play dead? Jason Isaacs is convincing, however one-sidedly ruthless, as the gung-ho officer who believes that the English have no right to play by the rules of war if they want to win, and Mel Gibson, photogenic as ever, mirrors the complexity of Tom Wilkinson's Cornwallis.

COVID-19 Global Cases
Last updated: N/A
Footnotes
Methodology Note
This data visualization uses a sankey diagram to responsibly display the overall reported cases and death toll of the 2019-2020 novel COVID-19 pandemic broken down by geography.
All reporting is at the country level with the exception of the United States which contains state-level detail.
Data sources
The data is derived from Johns Hopkins University Center for Systems Science and Engineering (JHU CSSE).
This visual uses consolidated data sources of the JHU CSSEE data sources from @covid19 and @NovelCOVID.
This dataset usually tracks 12-24 hours behind the latest reporting from JHU CSSE, so refer to their dashboard for the most up to date information.
Data Grouping
All countries that have reported less than 5,000 cases have been grouped in to one category labeled as "Other" to reduce visual noise in the visualization.
The United States is further broken down by state and groups the states in the "Other" category using a different threshold.
The specific threshold values are noted in the footnotes section.
Total Confirmed Metric
The JHU CSSE consolidated total of confirmed cases of COVID-19. Note that confirmed cases are just that, and there are an unknown quantity of unreported COVID-19 cases.
Total Deaths Metric
The JHU CSSE consolidated total COVID-19 related deaths reported by various governmental agencies.
Total Recovered Metric
The consolidated total reported recovered cases. Keep in mind that the reporting of this metric is likely to be inconsistent across global government agencies.
Active Cases Metric
The visualization computes this number by subtracting the total recovered and total deaths from the total confirmed cases:
Active Cases = Total Confirmed - Total Deaths -
Total Recovered
Death Rate
The visualization computes this number by dividing the Total Deaths metric by the Total Confirmed cases:
Death Rate = Total Deaths / Total Confirmed
The technical term for this ratio is the Case Fatality Rate (CFR). The CFR is different than the Crude Mortality Rate (CMR) which calculates the likelihood of someone in the general population dying from the virus.


Project4: due on May 10th, 2019 at 11:59:59pm (EDT).
I. Cryptocurrency and mining:
This project is based on your project3 and you are expected to build your own
cryptocurrency and minig it.
Step1:
First, you need to find a name for your new currency, such as "VikingCoin". You cannot
call it bitcoin or ether or any other existing cryptocurrency. You will create a Miner
class (see below). Your Miner will take newly-created transanction and collect transaction
into blocks. Each new block will include a "coin base" transaction that created
VikingCoin (or whatever).
You will need to denominate your cryptocurrency in 1/1000s (milli-coins).
So, as an example, 1 "VikingIron" is 0.001 "VikingCoin".
You are to create a new class/structure called TxnMemoryPool, which can be any
type you wish, but a simple list of Transaction objects/structures will do
(order is unimportant), and this will store your transactions in memory during
processing. Note you will no longer be automatically adding transactions
to blocks on creation of the transactions. Rather, you will add them to the
TxnMemoryPool on creation. This will simulate receiving them from the network.
If you plan to use multiple threads, you should set up a method or function
that creates a new unique transaction every 1-10 seconds (if using threads,
you can make this decision as you progress through your testing) and adds
each new transaction to the TxnMemoryPool. If you plan not to use multiple
threads, you may simply pre-create 91 new transactions and add them to your
TxnMemoryPool before beginning mining, which may prove easier. You should
modify your blockchain code. There is a new MAX_TXNS field, which is the
maximum number of transactions per block. You should set this to 10
(including the coinbase transaction). So 9 transactions + 1 coinbase
transaction = 10 Max.
Regarding the input and output, you could simply stuff a hash of the current
timestamp+some_randomly_generated_number into the inputs, and no one will be
the wiser. For outputs, you are expected to create an Output class.
Output
-value:int
-index:int
-script:String
Note that it is up to you to determine the best "decimal" format for your
particular language. That may be a Decimal object (serialized), or an int
(knowing that any Value is denominated in 1/1000s of your currency).
So if you placed a "1500" in your Value, that would mean 1.5 "VikingCoin".
At this point, you can put anything you want in the string Script.
Step2:
You will create a new Miner class/function, that will go through the
TxnMemoryPool (which will eventually be growing at a steady rate), and
your Miner will attempt to create a block whose Blockhash is less than
the target you will set. In this lab, our target will be calculated as:
Target = coefficient*2^(0x8 * (exponent-0x3))
Your Header.Bits (for all blocks) will default to 0x207fffff, with is the
difficulty bits for Regtest. This means that your coefficient will be
'0x7fffff' and your exponent will be '0x20'. Note that this is just
a starting default.  Feel free to
adjust your bits in order to play around with different levels of difficulty
if you get bored. In our case for this assignment, you will not need to
worry about automatically adjusting the mining difficulty. For example,
for a little more challenge, you could try the difficulty bits value
used on Testnet: 0x1d00ffff. When you are done experimenting, you will
want to reset your Header.Bits to the default of 0x207fffff for final
submission.
As you build your candidate blocks, keep in mind you will need a coinbase
transaction as the first transaction in each of the blocks.
This coinbase transaction will create an amount of your cryptocurrency
that is also up to you. You could follow the bitcoin model and start
out with 50 bitcoins, or you could be more or less generous. That's
entirely up to you.
Step3:
You want to write a test case in which you run your new Blockchain mining.
You will create a new Blockchain and doing so you will create your genesis block.
After mining the transactions in the TxnMemoryPool, print out the block height
of the tip of the chain.
Submission:
- Create a folder and name it as your (Linux) user name, e.g., hwang.
- Copy all your files to the above folder.
- Compile a README file, provide the following information
- Project description
- Provide an instruction how to compile and run your code, as well as a sample run.
- Existing bugs (things not finished)
- Log in grail, go to the parent director of the folder you created, and run (suppose the your folder is "hwang")
turnin -c cis593w -p proj4 hwang
If there is no error message, your submission is successful.
- Your most recent submission will always automatically overwrite the previous one.

Prototyping self-organized systems
Exploring the potential of Open Value Networks for a P2P Society
I am founder of bitmind.co, a decentralized Research & Development organization whose goal is the exploration of the potential of Open Value Networks (OVN). Our goal is to help Open Enterprises, Cooperatives and Communities to distribute value amongst their members and bootstrap their collective intelligence.
To do that, we focus our efforts in applied research & open source development around the OVN/DCO context, exploring how new models for self-organization can enforce the value production capacities within the P2P paradigm. In order to unify concepts, share common metodologies and explore this vaste field, we have also developed ovn.space, a shared hub for this evolving and growing ecosystem.
In ovn.space we are trying enable collaboration between different Open Value Networks. It has become apparent that the development and promotion of the OVN model of production requires a focused effort by the network of people that are working on it. This is required so as to acquire data and experiences from each group on the practices that work and those that do not so as to converge into a set of good methodologies. At the same time, the more the network shows that it has a strong mass, the easier it is to acquire funding from governments or potential investors, determine favourable policy changes or inspire people around the world to join us.

<IP_ADDRESS>. Parameter Estimation¶
Parameter Estimation methods (also known as non-linear least squares methods) are used to fit a set of m observations (in this tool defined in the QoI tab) with a model that is non-linear with n unknown parameters (in thus tool the unknown parameters are defined in the RV tab) \((m \ge n)\). The method are obtaining the parameters that best fits the experimental results, that is that minimizes the QoI, given no prior estimation as to the distribution associated with the random variables. As such the processing scripts should leave in the results.out
file differences between observed response and simulated response. The algorithms employed will find a set of parameters that minimizes these differences. The algorithms themselves are general functional minimization algorithms seeking to minimize:
where \(R_i\) might be the difference between experimental data \(y_i^{experiment}\) and model predictions \(y(x)_i^{model}\) for a response quantity at a particular location and/or time step, \(w_i\) optional weights, and \(x \in R^n\) the \(n\) model parameters which are not precisely known and are being calibrated to match available data.
The panel that is presented to the user when this Dakota Category is chosen, is as shown below.
Note
The unknown parameters (the random variables options in the RV tab) are limited to Continuous Design. The user provides min, max and starting point values for each random variable.
For parameter estimation two different optimization algorithms are currently provided under the Method drop down menu, namely OPT++GaussNewton and NL2SOL. For both methods three input parameters need to be specified as shown in the figure: 1. the convergence tolerance 2. the maximum number of iterations for the optimization subroutine. 3. the weights, \(w_i\), for each of the QoI. If no weights are specified, then \(w_i = 1.0\).
OPT++GaussNewton¶
OPT++ Provides a Gauss-Newton least squares capability which, on zero-residual test problems, can exhibit quadratic convergence rates near the solution. As a consequence, a good starting point values for the parameters should be provided. The Hessian is constructed with a Gauss-Newton approximation and the OPT++ Optimization routines are used.

Meza, R. A. Oliva, P. D. Hough, and P. J. Williams, “OPT++: An Object Oriented Toolkit for Nonlinear Optimization”, ACM Transactions on Mathematical Software, Volume 33, Number 2, June 2007.
NL2SOL¶
The NL2SOL method is based on an adaptive nonlinear least-squares algorithm, devised by Dennis and colleagues[Dennis81]. NL2SOL uses a trust region method and adaptively switches between two Hessian approximations, the Gauss-Newton approximation alone and the Gauss-Newton approximation plus a quasi-Newton approximation to the rest of the Hessian. This later approximation being useful when the starting guess is far from solution. For problems with large number of residuals, this algorithm is known to be more reliable than Gauss-Newton.

type acts as an owner of an underlyingAtkAction
instance. It provides the methods that can operate on this data type throughActionProtocol
conformance. UseAction
as a strong reference or owner of aAtkAction
instance.AtkAction
should be implemented by instances ofAtkObject
classes with which the user can interact directly, i.e. buttons, checkboxes, scrollbars, e.g. components which are not “passive” providers of UI information.Exceptions: when the user interaction is already covered by another appropriate interface such as
AtkEditableText
(insert/delete text, etc.) orAtkValue
(set value) then these actions should not be exposed byAtkAction
as well.Though most UI interactions on components should be invocable via keyboard as well as mouse, there will generally be a close mapping between “mouse actions” that are possible on a component and the AtkActions. Where mouse and keyboard actions are redundant in effect,

The
HyperlinkImpl
type acts as an owner of an underlyingAtkHyperlinkImpl
instance. It provides the methods that can operate on this data type throughHyperlinkImplProtocol
conformance. UseHyperlinkImpl
as a strong reference or owner of aAtkHyperlinkImpl
instance.AtkHyperlinkImpl allows AtkObjects to refer to their associated AtkHyperlink instance, if one exists. AtkHyperlinkImpl differs from AtkHyperlink in that AtkHyperlinkImpl is an interface, whereas AtkHyperlink is a object type. The AtkHyperlinkImpl interface allows a client to query an AtkObject for the availability of an associated AtkHyperlink instance, and obtain that instance. It is thus particularly useful in cases where embedded content or inline content within a text object is present, since the embedding text object implements AtkHypertext and the inline/embedded objects are exposed as children which implement AtkHyperlinkImpl, in addition to their being obtainable via AtkHypertext:getLink followed by AtkHyperlink:getObject.
The AtkHyperlinkImpl interface should be supported by objects exposed within the hierarchy as children of an AtkHypertext container which correspond to “links” or embedded content within the text. HTML anchors are not, for instance, normally exposed this way, but embedded images and components which appear inline in the content of a text object are. The AtkHyperlinkIface interface allows a means of determining which children are hyperlinks in this sense of the word, and for obtaining their corresponding AtkHyperlink object, from which the embedding range, URI, etc. can be obtained.
To some extent this interface exists because, for historical reasons, AtkHyperlink was defined as an object type, not an interface. Thus, in order to interact with AtkObjects via AtkHyperlink semantics, a new interface was required.

AtkPlug
,AtkSocket
provides the ability to embed accessibles from one process into another in a fashion that is transparent to assistive technologies.AtkSocket
works as the container ofAtkPlug
, embedding it using the methodatk_socket_embed()
. Any accessible contained in theAtkPlug
will appear to the assistive technologies as being inside the application that created theAtkSocket
.The communication between a
AtkSocket
and aAtkPlug
is done by the IPC layer of the accessibility framework, normally implemented by the D-Bus based implementation of AT-SPI (at-spi2). If that is the case, at-spi-atk2 is the responsible to implement the abstract methodsatk_plug_get_id()
andatk_socket_embed()
, so an ATK implementor shouldn’t reimplement them. The process that contains theAtkPlug
is responsible to send the ID returned byatk_plug_id()
to the process that contains theAtkSocket
, so it could call the methodatk_socket_embed()
in order to embed it.For the same reasons, an implementor doesn’t need to implement

Negotiation of content type is allowed. Clients may examine the backing data and transform, convert, or parse the content in order to present it in an alternate form to end-users.
The AtkStreamableContent interface is particularly useful for saving, printing, or post-processing entire documents, or for persisting alternate views of a document. If document content itself is being serialized, stored, or converted, then use of the AtkStreamableContent interface can help address performance issues. Unlike most ATK interfaces, this interface is not strongly tied to the current user-agent view of the a particular document, but may in some cases give access to the underlying model data.

Table
type acts as an owner of an underlyingAtkTable
instance. It provides the methods that can operate on this data type throughTableProtocol

as a strong reference or owner of aAtkTable
instance.AtkTable
should be implemented by components which present elements ordered via rows and columns. It may also be used to present tree-structured information if the nodes of the trees can be said to contain multiple “columns”. Individual elements of anAtkTable
are typically referred to as “cells”. Those cells should implement the interfaceAtkTableCell
, butAtk
doesn’t require them to be direct children of the currentAtkTable
. They can be grand-children, grand-grand-children etc.AtkTable
provides the API needed to get a individual cell based on the row and column numbers.Children of
AtkTable
are frequently “lightweight” objects, that is, they may not have backing widgets in the host UI toolkit. They are therefore often transient.Since tables are often very complex,
AtkTable
includes provision for offering simplified summary information, as well as row and column headers and captions. Headers and captions areAtkObjects
which may implement other interfaces (AtkText
,AtkImage
, etc.) as appropriate.AtkTable
summaries may themselves be (simplified)AtkTables
, etc.Note for implementors: in the past,
See moreAtkTable
required that all the cells should be direct children ofAtkTable
, and provided some index based methods to request the cells. The practice showed that that forcing madeAtkTable
implementation complex, and hard to expose other kind of children, like rows or captions. Right now, index-based methods are deprecated.Declaration

type acts as an owner of an underlyingAtkText

as a strong reference or owner of aAtkText
instance.AtkText
should be implemented byAtkObjects
on behalf of widgets that have text content which is either attributed or otherwise non-trivial.AtkObjects
whose text content is simple, unattributed, and very brief may expose that content viaatk_object_get_name
instead; however if the text is editable, multi-line, typically longer than three or four words, attributed, selectable, or if the object already uses the ‘name’ ATK property for other information, theAtkText
interface should be used to expose the text content. In the case of editable text content,AtkEditableText
(a subtype of theAtkText
interface) should be implemented instead.
See moreAtkText
provides not only traversal facilities and change notification for text content, but also caret tracking and glyph bounding box calculations. Note that the text strings are exposed as UTF-8, and are therefore potentially multi-byte, and caret-to-byte offset mapping makes no assumptions about the character length; also bounding box glyph-to-offset mapping may be complex for languages which use ligatures.Declaration

The
Value
type acts as an owner of an underlyingAtkValue
instance. It provides the methods that can operate on this data type throughValueProtocol
conformance. UseValue
as a strong reference or owner of aAtkValue
instance.AtkValue
should be implemented for components which either display a value from a bounded range, or which allow the user to specify a value from a bounded range, or both. For instance, most sliders and range controls, as well as dials, should haveAtkObject
representations which implementAtkValue
on the component’s behalf.AtKValues
may be read-only, in which case attempts to alter the value return would fail.On the subject of current value text In addition to providing the current value, implementors can optionally provide an end-user-consumable textual description associated with this value. This description should be included when the numeric value fails to convey the full, on-screen representation seen by users. Password strength A password strength meter whose value changes as the user types their new password. Red is used for values less than 4.0, yellow for values between 4.0 and 7.0, and green for values greater than 7.0. In this instance, value text should be provided by the implementor. Appropriate value text would be “weak”, “acceptable,” and “strong” respectively.A level bar whose value changes to reflect the battery charge. The color remains the same regardless of the charge and there is no on-screen text reflecting the fullness of the battery. In this case, because the position within the bar is the only indication the user has of the current charge, value text should not be provided by the implementor.
Implementor Notes Implementors should bear in mind that assistive technologies will likely prefer the value text provided over the numeric value when presenting a widget’s value. As a result, strings not intended for end users should not be exposed in the value text, and strings which are exposed should be localized. In the case of widgets which display value text on screen, for instance through a separate label in close proximity to the value-displaying widget, it is still expected that implementors will expose the value text using the above API. AtkValue
should NOT be implemented for widgets whose displayed value is not reflective of a meaningful amount. For instance, a progress pulse indicator whose value alternates between 0.0 and 1.0 to indicate that some process is still taking place should not implementAtkValue
because the current value does not reflect progress towards completion.On the subject of ranges In addition to providing the minimum and maximum values, implementors can optionally provide details about subranges associated with the widget. These details should be provided by the implementor when both of the following are communicated visually to the end user: The existence of distinct ranges such as “weak”, “acceptable”, and “strong” indicated by color, bar tick marks, and/or on-screen text. Where the current value stands within a given subrange, for instance illustrating progression from very “weak” towards nearly “acceptable” through changes in shade and/or position on the bar within the “weak” subrange. If both of the above do not apply to the widget, it should be sufficient to expose the numeric value, along with the value text if appropriate, to make the widget accessible. Implementor Notes If providing subrange details is deemed necessary, all possible values of the widget are expected to fall within one of the subranges defined by the implementor. On the subject of localization of end-user-consumable text values Because value text and subrange descriptors are human-consumable, implementors are expected to provide localized strings which can be directly presented to end users via their assistive technology. In order to simplify this for implementors, implementors can use atk_value_type_get_localized_name()
with the following already-localized constants for commonly-needed values can be used:ATK_VALUE_VERY_WEAK ATK_VALUE_WEAK ATK_VALUE_ACCEPTABLE ATK_VALUE_STRONG ATK_VALUE_VERY_STRONG ATK_VALUE_VERY_LOW ATK_VALUE_LOW ATK_VALUE_MEDIUM ATK_VALUE_HIGH ATK_VALUE_VERY_HIGH ATK_VALUE_VERY_BAD ATK_VALUE_BAD ATK_VALUE_GOOD ATK_VALUE_VERY_GOOD ATK_VALUE_BEST ATK_VALUE_SUBSUBOPTIMAL ATK_VALUE_SUBOPTIMAL ATK_VALUE_OPTIMAL Proposals for additional constants, along with their use cases, should be submitted to the GNOME Accessibility Team.

Some days ago I was wondering why open-source communities are so cool! You can meet a lot of interesting people, who devote a lot time of their time-lifes just to create stuffs that other people will use. It is strange. Usually, this people actually have their own business, work, family, whatever, and they still find time to work for free. It sounds weird to me (even though I devote part of my time to open-source activities).
But, the point is: how active these communities are? And if you take into consideration only the Brazilian community, what is the general picture that we can drawn from they? Thinking about it, I collected a lot of data about Brazilian developers in the github social coding website. There is a lot of interesting findings.
1. Are the brazilian open-source community active
Not as I expected. I gathered data for a total of 4.481 users, which 3.121 ones do not have any kind of contribution. That is, 30% of the users (the active group) are responsible for 100% of the contribution. The active group was sub-divided in more three groups: low active (up to 19 contribution per year), fairly active (up to 49 contributions per year) and very active (more than 49 contributions per year). Furthermore, the percentage of the low actives, fairly actives and very actives are, respectively, 57.8%, 20.9%, 21.3%. The Pareto’s principle also works here: from 30% of the users come the 100% of the contributions. This results show us that the brazilian open-source community is not so active as we may guess.
2. From where they come?
If we take into consideration the user locale, we observed that 46% of these users come from the Northeast region, which is very interesting, since, here in Brazil, the most economical region (or, in this case, from where have the most job offers) is the southeast region. If we take into consideration the specific State, the most active are Paraná (13.65%), followed by Ceará (12.37%) and followed by (11.25%). All theses states are not part of the southeast region. Nonetheless, this kind of analysis is very difficult to perform, since the user can omit the location field (which represents 8% of the total), provide unreliable information, or use acronym, nicknames, etc. But, if we can draw a chart of the Brazilian open-source contribution per state, it may look like this one.
3. Which are the most popular programming languages?
Github can infer the most used language on a given project. Then, analyzing the set of projects contributed, the list of the ten more used programming language are: JavaScript (22.77%), Ruby (18.78%), Java (14.19%), PHP (13.95%), Python (9.86%), C (3.36%), C++ (2.94%), Shell (2.55%), Objective-C (1.95%) e C# (1.88%). I have to tell that these results surprised me a bit. Since I’m a Java-guy, my heart used to fell that Java is the most popular language in Brazil. But, it seems that Brazilian hackers are more likely to use untyped languages, such as JS, Ruby, PHP, although the Java language remains in the top-3. It is cool.
Now I’m wondering if these data are only related to github, or if it could be possible to generalize. Someday I want to correlate this result with stackoverflow, or other similar forge.

For years, the jQuery Foundation has supported the development, growth and administration of the jQuery projects as well as non-jQuery projects like QUnit, Sizzle and Globalize with the goal of making the open web accessible to everyone. With that goal in mind, the jQuery Foundation has opened its doors to other open source projects that are dedicated to that same mission and are vital pieces to the open web ecosystem. But what does that mean for your project and what would your project get out of joining the jQuery Foundation? Those are good questions that we hope to answer here.
When your project joins the Foundation, we'll take care of the administrative, legal, and financial aspects of keeping your project running. We can also provide infrastructural resources and perform various supporting tasks so that the development team can focus on the project and their community.
Projects enter the jQuery Foundation in different states. If necessary, we will help a project determine their team structure, leadership and communication infrastructure. The Foundation does not micromanage the technical direction of the project, leaving direction to the project team and its community.
The jQuery Foundation has years of experience building and nurturing a community around its projects and we want to give you access to that experience. Whether your project is new or established, you can always work toward growing your community and making sure you are meeting their needs. We want to help you do that.
Projects will have access to jQuery Foundation hardware and services as well as a team dedicated to keeping it all running. The Foundation will provide resources for websites, documentation, builds, CDN access and more. We also have an ever growing stock of mobile devices available for project testing.
Whether or not your project currently brings in funding, we are here to help. All of our projects share in a single budget. Based on available funds, project goals/needs and a group prioritization system, we allocate those funds in the best way possible for all projects. This means that large projects with a good funding base, like jQuery for example, receive help in allocating that money most effectively and they also help smaller or less funded projects continue to move forward.
The jQuery Foundation will register and protect any trademarks and intellectual property belonging to a project and will protect all projects under jQuery Foundation copyright. The Foundation will also provide or help with the creation of a Contributor License Agreement for each project as well as license selection and management. Projects have access to our legal team as well if the need arises.
Our projects are accepted because we believe they are important to the open web and its future. With that in mind, we provide vendor-neutral forums such as mailing lists and other communication channels as well as in person meetings and conferences for our projects to collaborate and work together toward common goals as well as pull from the experiences and knowledge of those other projects. We think this is a unique and very important advantage of being part of the jQuery Foundation. Your project is not siloed but instead encouraged to be a contributing part of the Foundation ecosystem.
The Foundation's goal is to provide Open Source projects with the financial, logistical, and administrative resources they need to ensure each project is successful. If a project's leadership wishes to leave the Foundation at some point in the future, it is free to do so. The Foundation will transfer relevant marks and copyrights to a nonprofit organization that is committed to respecting the open source license of the project. The jQuery projects made a similar transition from the Software Freedom Conservancy in 2012 when the jQuery Foundation was created.
The Foundation offers projects support without micro-managing their technical decisions, and sets a few basic best practices for all projects, such as tagging for all releases. Projects determine their own release schedules, feature sets, team members, and tool sets.
So you've decided that your project would fit into the jQuery Foundation family, great! We want to hear from you. We don't have a set application procedure but we do have some guidelines we follow when accepting new projects. Many projects won't meet all of these guidelines, and that's ok. It's more about providing talking points for the Foundation to get to know and evaluate a potential project.
The Foundation wants to know if the goals and purpose of the project fit into the community of projects we currently support. We want our projects to benefit from each other and provide a wealth of knowledge and experiences that they can all draw from.
In many cases this means the project is already widely used, and needs support so it can continue to grow and serve the web development community. In a few cases it may mean that, in the judgement of the Foundation, a small project is important to the future of web development.
It's great when a project maintains a consistent style and organization to the code in their project. But more than that, we want to see that there is a team of people, large or small, that is willing to continue to grow and maintain that project with the support of the Foundation.
We prefer a small number of licenses like MIT or BSD style licenses. We will consider other licenses but our goal is to maintain the openness of a project and the license must reflect that.
