There's a lack of sufficient transparency with regards to the real world impact of ML models. The power and information asymmetries between people and consumer technology companies employing algorithmic systems are legitimized through contractual agreements which have failed to provide people with meaningful consent and contestability, in cases of experiences of algorithmic harms.
- Improved understanding of the challenges that exist in current approaches to transparency of consent and dispute resolution mechanisms put in place by tech companies.
- Evaluation of computable contracts as a transparent socio-technical intervention that builds agency in consumer use of AI.
A feminist-inspired social, computational, and legal contract for restructuring power asymmetries and center-periphery dynamics to enable improved human agency in individual and collective experiences of algorithmic harms. It is a provocation and a speculative imaginary centered on the notions of co-constitution, through participatory mechanisms; accountability, through reparation, apology, and forgiveness; positive friction through enabling meaningful dialogue in the production and resolution of conflict; verification through open-sourced computational tools; and veto-power reflecting the temporal dynamics of how individual and collective experiences of algorithmic harm unfold.

I've been part of the core team at the IEEE P7010 working group developing a recommended practice
for Assessing the Impact of Autonomous and Intelligent Systems on Human Well-Being. Incorporating well-being factors throughout the lifecycle of
AI is both challenging and urgent and IEEE 7010 provides key guidance for those who design, deploy, and procure these technologies.
Read an overview paper introducing the standard here.
I'm also the lead guest editor of an upcoming special issue of the Springer International Journal of Community Well-being focused on the intersections of AI and
community well-being. The special issue explores three topic areas including well-being metrics framework for AI, how can AI protect community well-being from threats, as well as how can AI itself be a threat to communities and what can communities do to mitigate, manage, or negate such threats.
Bringing awareness to our inherent positionality, we gain new perspectives about the relational nature of (un)intended consequences of AI systems. Giving examples from a recent ethnographic study in the intersection of organizational structure and the work on ensuring the responsible development and use of AI, we investigate the so-called socio-technical context - the lived experience of some of the people actively involved in the AI ethics field. Learning from the field of Participatory Relational Design, we investigate what can we learn from the design of social movements (specifically in the Global South) about the way we work to ensure better alignment between AI systems and human and ecological well-being.
This research paper explored the dynamics of the repeated interactions between a user and a recommender system, leveraging the human-in-the-loop system design from the field of Human Factors and Ergonomics. We go on to derive a human-algorithmic interaction metric called a barrier-to-exit which aims to be a proxy for quantifying the ability of the AI model to recognize and allow for change in user preferences.

Once an accessory or bridge has been created, and is turned on, it can be discovered by the iOS device via the HomeKit API. Once the accessory or bridge has been selected, a prompt will appear on the iOS device to enter the Setup Code either via the camera or manually.
-
Note that for bridged accessories, the pairing process happens with the bridge and not with the bridged accessory itself. To view the Setup Code, select the accessory or bridge from the accessory list on the left side of the window. The Setup Code is displayed in the top area of the main view.
-
An accessory or bridge only needs to be paired to a device once. After the initial pairing process, the device will reconnect to the accessory or bridge when it is reachable and will not require a Setup Code again.
-
The number of devices paired with the accessory or bridge is shown below the Setup Code and accessory Category. To remove all of the accessory pairings, select the "Reset" button to the right of the number of pairings.

ProblemDrag and drop an element on the web pageSolutionBrython implements an API based on HTML5 drag and drop specification. In the basic form presented in this example, it consists in defining callback functions for 3 events : - dragstart on the draggable element (when the user starts dragging it) - dragover on the destination zone (when the draggable element is moved over it) - drop on the destination zone (when the user releases the mouse button) To attach the function callback to an event on an element, we use the method element.bind(event,callback)
The callback functions take a single argument, an instance of DOMEvent . To communicate information during the drag and drop operation, the event has an attribute data that receives a value in the callback associated to dragstart ; this value is used in the callback associated with drop to identify the element that is being dropped
In the example, when the draggable object has been dropped, it can't be dragged any more ; for this, we remove the bindings attached to an event on this object using the method element.unbind(event)

You must be wondering what an Akan Name Generator is let alone an Akan name so i'm going to briefly explain both of these terms for you. Akan names are derived from Ghanian culture. Frequently in Ghana, children are given their first name as a 'day name' which corresponds to the day in the week that they were born. These names differ based on the gender of the child as illustrated on the sidebars.
We can now understand what an Akan Name Generator does. Its main function is to give you your Akan name based on the day that you were born and based on your gender similar to how children in Ghana are named. So lets try it out shall we?

Bale set to become a Manchester United player in January, Pogba to leave: Premier League rumours
by Rhys ThomasManchester United could finally land Gareth Bale.
Gareth Bale is set to become a Manchester United player in January, according to the Sun on Sunday.
Manchester United have long been linked with Bale, and with Real Madrid keen to offload the Welshman's wages, a deal could be on the cards in January.
French star Paul Pogba would likely move in the opposite direction as part of the deal.
Reportedly Real are confident a deal can be done in January, yet could wait until the summer.
Bale's camp are said to be very keen to leave the Spanish capital, having endured a frosty relationship with Zinedine Zidane.

French giants PSG are supposedly interested in Liverpool midfielder Adam Lallana. (Sunday Mirror)
Manchester City may look to bring in Bayern Munich winger Kingsley Coman, should Leroy Sane move the other way. (Daily Mirror)

Source separation for towed-streamer marine data via sparsity promotion
This application is available only in the software release for members of SINBAD consortium.
This package contains a MATLAB implementation of a 2-D over/under blended marine acquisition scheme, and a deblending (or source separation) algorithm based on sparsity-promoting inversion in the curvelet domain using L1 minimization.
Author: Haneet Wason<EMAIL_ADDRESS>Date: July, 2016
Contents
Downloading & Dependencies
The code can be found in the SLIM sofware release under applications/Acquisition/SourceSeparationL1.
The code has been tested with Matlab R2015b.
This code uses the following packages, also found in the tools part of the SLIM software release.
- utilities/SPOT - object oriented framework for matrix-free linear algebra.
- utilities/SegyMAT - Matlab/Octave toolbox for reading and writing SEG-Y formatted files.
- functions/misc - miscellaneous functions.
- solvers/SPGL1-SLIM - SLIM version of SPGL1 solver.
The CurveLab package is downloaded from the tools part of the SLIM-release-comp repository. * transforms/CurveLab-2.1.2-SLIM - curvelet transform functions.
Functions
Some functions specific to this package can be found in the applications/Acquisition/SourceSeparationL1/misc_funcs directory.
Running & Parallelism
All the examples and results are produced by the scripts found in this software release under applications/Acquisition/SourceSeparationL1. Start matlab from that directory or run startup in that directory to add the appropriate paths.
To run the scripts follow the instructions in the README file under applications/Acquisition/SourceSeparationL1/examples. The scripts are run in serial mode but can also be run in parallel with slight modifications to the code. Please see the README file.
Read more about SLIM's approach to parallel computing in Matlab.
Examples and results
Examples and results are shown here. Scripts to reproduce the results can be found under applications/Acquisition/SourceSeparationL1/examples.

Just got it twice more, though this was after I had to restart the server, and then it went all jumpy on me before the 2nd time, so these might have been due to server problems. Still, I doubt I'm supposed to be getting this quest this many times, and certainly not all the way up to lvl 10!

Hm. Either the server's having a really bad day or there's something in the questing system that's making it jumpy. I suspect the former but wouldn't rule out the latter.

The blade horrors quest isn't limited for the only reason that these quests were designed to test a variety of parameters--this quest tests both specific monster kills and overall monster kills.
Oh and yes, the server's having a pretty bad day.

Good to know. It seems to be working well on that count. One thing though: I wasn't able to repeat the quest right away, but after I completed it the first couple times I got the "come back when you're stronger message." Is that supposed to happen, or should it be immediate?

I reported to the recipient after time had expired. Obvious fail. But then the sender wouldn't re-offer. But when I give up the quest (either before or after the time expires), I can get the offer again. Also, if I drop the letter on the ground it has no icon. Oops.

Our tension against a kill counter was that it seems to make quests less engaging and more artificial. Since the point is to be able to check your quest's progress without returning to town, what about color-coding some of the text so that stuff you've done turns green (for example) and as you get closer to completing a task, it changes color.

Since the point is to be able to check your quest's progress without returning to town, what about color-coding some of the text so that stuff you've done turns green (for example) and as you get closer to completing a task, it changes color.

With the significant increase in the ability to access the web on mobile devices — first on laptops, then phones and now tablet devices, it is now easier to access your data and your apps wherever you go. Or is it?
This article was written on a train from London to Liverpool. The train has Wifi, I have a 3G data card, yet I am still never fully connected. Besides, many online tools today can't handle this intermediate state of connectivity properly.
So how do we solve this problem? It is not simple, but there are steps that you can take today that will let your users use your app whereever they are. Some of these steps have direct solutions implemented in HTML; some will require you to implement some logic, all will help you build a better app.
Users are conditioned to not enter a URL when they are not online because they know they will get an error page. But it doesn't have to be this way. It is possible to build applications that will load even when there is no Internet connection.
You should build your application to present a consistent UI to your users so that even if they are offline, they can still see and use some of your application. This will allow you to detect presence of a network connection and inform the user of the connection requirements of your application in a graceful, friendly manner.
Following our AppCache tutorial, you will see that it is pretty easy to get this into existing apps. Your application will include a link to a manifest file, and that manifest file will contain all the files that encompass your application.
CACHE: /js/logic.js /js/options.js /images/loading.png /css/main.css
The browser then ensures that these assets are cached offline until the next time that the manifest file is updated.
Now that you can make your app load and present a consistent interface to your users even when you are offline, you need to detect when there is Internet connectivity. This is especially important if your app needs an Internet connection to function properly.
HTML5 defines an event that signals when your app has connectivity. This is the simplest approach, yet it is not supported in all browsers. It is also not guaranteed to be accurate. Most implementations of the API watch for changes in the local network interface to determine if your application is online or not. But what if your network interface is up, but your router is down? Are you offline or online?
It is simple to check if you are online by querying window.navigator.onLine
if (navigator.onLine) { alert('online') } else { alert('offline'); }
You can also be told when there is a change in the network state. Just listen for the for the events on window.onOnline and window.onOffline
window.addEventListener("offline", function(e) { alert("offline"); }, false); window.addEventListener("online", function(e) { alert("online"); }, false);
The API is straightforward, how do you get it to work if the API isn't implemented in the browser?
It is possible to use a couple more signals to detect if you are offline including side-effects of the AppCache and listening to the responses from XMLHttpRequest.
The AppCache system always makes an attempt to request the manifest to check to see if it needs to update its list of assets. If that requests fails it is normally one of two things, the manifest file is no longer being used (that is, it is not hosted) or the system is unable to access the network to fetch the file.
window.applicationCache.addEventListener("error", function(e) { alert("Error fetching manifest: a good chance we are offline"); });
Detecting this request failure is a good indication of whether you have a network connection or not.
Network connections can fail during the use of your application, so how do you detect this?
A large number of applications built today use XMLHttpRequest to fetch data from the server while keeping the user inside the page. XMLHttpRequest defines an event for when an error occurs on the network. You can use this to determine if you have a network connection.
Once you build your application to be able to handle these errors you can then interact with localStorage methods to store and fetch cached data in the presence of network failure.
The following code is a great example of a "fetch" function that is able to respond to network failures.
var fetch = function(url, callback) { var xhr = new XMLHttpRequest(); var noResponseTimer = setTimeout(function() { xhr.abort(); if (!!localStorage[url]) { // We have some data cached, return that to the callback. callback(localStorage[url]); return; } }, maxWaitTime); xhr.onreadystatechange = function() { if (xhr.readyState != 4) { return; } if (xhr.status == 200) { clearTimeout(noResponseTimer); // Save the data to local storage localStorage[url] = xhr.responseText; // call the handler callback(xhr.responseText); } else { // There is an error of some kind, use our cached copy (if available). if (!!localStorage[url]) { // We have some data cached, return that to the callback. callback(localStorage[url]); return; } } }; xhr.open("GET", url); xhr.send(); };
Watching for this error event is pretty easy, but passing the result out as a return value becomes quickly cubmersome and prone to errors. Luckily, the HTML DOM has a rich event mechanism that you can hook in to, to create a custom "offline/online" event.
var fireEvent = function(name, data) { var e = document.createEvent("Event"); e.initEvent(name, true, true); e.data = data; window.dispatchEvent(e); };
Integrating the "fireEvent" method into our "fetch" function allows us to respond to events based on the network connectivity and gives us the freedom to build applications that are not tied to monitoring the returned data from a method.
var fetch = function(url, callback) { var xhr = new XMLHttpRequest(); var noResponseTimer = setTimeout(function() { xhr.abort(); fireEvent("connectiontimeout", {}); if (!!localStorage[url]) { // We have some data cached, return that to the callback. callback(localStorage[url]); return; } }, maxWaitTime); xhr.onreadystatechange = function(e) { if (xhr.readyState != 4) { return; } if (xhr.status == 200) { fireEvent("goodconnection", {}); clearTimeout(noResponseTimer); // Save the data to local storage localStorage[url] = xhr.responseText; // call the handler callback(xhr.responseText); } else { fireEvent("connectionerror", {}); // There is an error of some kind, use our cached copy (if available). if (!!localStorage[url]) { // We have some data cached, return that to the callback. callback(localStorage[url]); return; } } }; xhr.open("GET", url); xhr.send(); };
We can now build applications that are notified when there is a failure somewhere in the network.
window.addEventListener("connectionerror", function(e) { alert("There is a connection error"); });
Using the exact same structure that we in the XML Http Request example, it is possible to periodically check a file on the network to see if there is a network connection.
setTimeout(function() { fetch("favicon.ico"); } , 30000);
Use this sparingly. If your service is popular this can produce an increased amount of traffic.
A common misconception with AppCache is the belief that all of your application's logic and assets must be cached for it to function offline. This is not the case. You can bootstrap just enough of your app to get it into a state where you can present a user interface to your users, and load the rest of the information in at run-time.
Lets have a look at a simple example:
-- index.html -- <html manifest="cache.manifest"> -- cache.manifest -- CACHE: /js/logic.js /js/options.js /images/loading.png /css/main.css NETWORK: *
It is very similar to the AppCache example in the first chapter, but note the inclusion of the “NETWORK:” section. Every request for data that is not in the CACHE section will be allowed out on to the network.
With this very simple method, we can then provide the minimum number of assets to get the application running, then once we detect that the page has loaded, we can use a JavaScript loaded to bring in the next set of assets which more completely define the application.
Script Loaders have been gaining acceptance in the Web Development community as a way to target load scripts and other against specific criteria. For example, if your browser doesn't support any client-side storage, then why load all that extra code?
Integrating a script loader into your projects can while combining it with our tests for offline support can allow you to build applications that will delight the user. Below is an example using the YepNope JavaScript framework.
yepnope({ test : isOnline, yep : ['normal.js', 'controller.js', 'assets.js'], nope : 'errors.js' });
The above example is sligthly contrived, but you can see how given knowledge of the connection state, you can easily start to load more of your application in at run-time, and, if offline load a different set of scripts that can handle the failure cases.
We gave it away a little earlier in our example "fetch" request.
To make applications useful, you must cache the data your app uses on the client. We achieved this by taking advantage of the simplicity of the localStorage API.
Every single request made by the XMLHttpRequest framework can either succeed or fail. If it is successful we store the results of the response against the URL. If there is a failure we check localStorage for the presence of the requested URL, and if there is data we return that.
if (xhr.status == 200) { clearTimeout(noResponseTimer); // Save the data to local storage localStorage[url] = xhr.responseText; // call the handler callback(xhr.responseText); } else { // There is an error of some kind, use our cached copy (if available). if (!!localStorage[url]) { // We have some data cached, return that to the callback. callback(localStorage[url]); return; } }
HTML5Rocks has many tutorials on offline technologies, where you can get hands-on with code examples.

database information organized as field separated lists
Standard RFC 4180In computing, a comma-separated values (CSV) file stores tabular data (numbers and text) in plain text. Each line of the file is a data record. Each record consists of one or more fields, separated by commas. The use of the comma as a field separator is the source of the name for this file format.
The CSV file format is not standardized. The basic idea of separating fields with a comma is clear, but that idea gets complicated when the field data may also contain commas or even embedded line-breaks. CSV implementations may not handle such field data, or they may use quotation marks to surround the field. Quotation does not solve everything: some fields may need embedded quotation marks, so a CSV implementation may include escape characters or escape sequences.
In addition, the term "CSV" also denotes some closely related delimiter-separated formats that use different field delimiters. These include tab-separated values and space-separated values. A delimiter that is not present in the field data (such as tab) keeps the format parsing simple. These alternate delimiter-separated files are often even given a [char46]csv extension despite the use of a non-comma field separator. This loose terminology can cause problems in data exchange. Many applications that accept CSV files have options to select the delimiter character and the quotation character.
CSV is a common data exchange format that is widely supported by consumer, business, and scientific applications. Among its most common uses is moving tabular data between programs that natively operate on incompatible (often proprietary or undocumented) formats.[1] This works despite lack of adherence to RFC 4180 (or any other standard), because so many programs support variations on the CSV format for data import.
For example, a user may need to transfer information from a database program that stores data in a proprietary format, to a spreadsheet that uses a completely different format. The database program most likely can export its data as "CSV"; the exported CSV file can then be imported by the spreadsheet program.
RFC 4180 proposes a specification for the CSV format, and this is the definition commonly used. However, in popular usage "CSV" is not a single, well-defined format. As a result, in practice the term "CSV" might refer to any file that:[2][5]
1. is plain text using a character set such as ASCII, various Unicode character sets (e.g. UTF-8), EBCDIC, or Shift JIS, 2. consists of records (typically one record per line), 3. with the records divided into fields separated by delimiters (typically a single reserved character such as comma, semicolon, or tab; sometimes the delimiter may include optional spaces), 4. where every record has the same sequence of fields. Within these general constraints, many variations are in use. Therefore, without additional information (such as whether RFC 4180 is honored), a file claimed simply to be in "CSV" format is not fully specified. As a result, many applications supporting CSV files allow users to preview the first few lines of the file and then specify the delimiter character(s), quoting rules, etc. If a particular CSV files variations fall outside what a particular receiving program supports, it is often feasible to examine and edit the file by hand (i.e., with a text editor) or write a script or program to produce a conforming format.
Comma-separated values is a data format that pre-dates personal computers by more than a decade: the IBM Fortran (level H extended) compiler under OS/360 supported them in 1972.[6] List-directed ("free form") input/output was defined in FORTRAN 77, approved in 1978. List-directed input used commas or spaces for delimiters, so unquoted character strings could not contain commas or spaces.[7]
The "comma-separated value" name and "CSV" abbreviation appear to have come into common use in 1983, in connection with the SuperCalc spreadsheet.[8]. The manual for the Osborne Executive computer, which bundled SuperCalc, documents the CSV quoting convention that allows strings to contain embedded commas, but does not specify a convention for embedding quotation marks within quoted strings.[9]
Comma-separated value lists are easier to type (for example into punched cards) than fixed-column-aligned data, and were less prone to producing incorrect results if a value was punched one column off from its intended location.
Comma separated files are used for the interchange of database information between machines of two different architectures. The plain-text character of CSV files largely avoids incompatibilities such as byte-order and word size. The files are largely human-readable, so it is easier to deal with them in the absence of perfect documentation or communication.[10]
The main standardization initiative transforming "de facto fuzzy definition" into a more precise and de jure one was in 2005, with RFC4180, defining CSV as a MIME Content Type. Later, in 2013, some of RFC4180s deficiencies were tackled by a W3C recommendation.[11]
In 2014 IETF published RFC7111 describing application of URI fragments to CSV documents. RFC7111 specifies how row, column, and cell ranges can be selected from a CSV document using position indexes.
In 2015 W3C, in an attempt to enhance CSV with formal semantics, publicized the first drafts of recommendations for CSV-metadata standards, that began as recommendations in December of the same year.[12]
CSV formats are best used to represent sets or sequences of records in which each record has an identical list of fields. This corresponds to a single relation in a relational database, or to data (though not calculations) in a typical spreadsheet.
The format dates back to the early days of business computing and is widely used to pass data between computers with different internal word sizes, data formatting needs, and so forth. For this reason, CSV files are common on all computer platforms.
CSV is a delimited text file that uses a comma to separate values (many implementations of CSV import/export tools allow other separators to be used). Simple CSV implementations may prohibit field values that contain a comma or other special characters such as newlines. More sophisticated CSV implementations permit them, often by requiring " (double quote) characters around values that contain reserved characters (such as commas, double quotes, or less commonly, newlines). Embedded double quote characters may then be represented by a pair of consecutive double quotes,[13] or by prefixing an escape character such as a backslash (for example in Sybase Central).
CSV formats are not limited to a particular character set.[1] They work just as well with Unicode character sets (such as UTF-8 or UTF-16) as with ASCII (although particular programs that support CSV may have their own limitations). CSV files normally will even survive naive translation from one character set to another (unlike nearly all proprietary data formats). CSV does not, however, provide any way to indicate what character set is in use, so that must be communicated separately, or determined at the receiving end (if possible).
Databases that include multiple relations cannot be exported as a single CSV file.
Similarly, CSV cannot naturally represent hierarchical or object-oriented database or other data. This is because every CSV record is expected to have the same structure. CSV is therefore rarely appropriate for documents such as those created with HTML, XML, or other markup or word-processing technologies.
Statistical databases in various fields often have a generally relation-like structure, but with some repeatable groups of fields. For example, health databases such as the Demographic and Health Survey typically repeat some questions for each child of a given parent (perhaps up to a fixed maximum number of children). Statistical analysis systems often include utilities that can "rotate" such data; for example, a "parent" record that includes information about five children can be split into five separate records, each containing (a) the information on one child, and (b) a copy of all the non-child-specific information. CSV can represent either the "vertical" or "horizontal" form of such data.
In a relational database, similar issues are readily handled by creating a separate relation for each such group, and connecting "child" records to the related "parent" records using a foreign key (such as an ID number or name for the parent). In markup languages such as XML, such groups are typically enclosed within a parent element and repeated as necessary (for example, multiple <child> nodes within a single <parent> node). With CSV there is no widely accepted single-file solution.
The name "CSV" indicates the use of the comma to separate data fields. Nevertheless, the term "CSV" is widely used to refer a large family of formats, which differ in many ways. Some implementations allow or require single or double quotation marks around some or all fields; and some reserve the very first record as a header containing a list of field names. The character set being used is undefined: some applications require a Unicode byte order mark (BOM) to enforce Unicode interpretation (sometimes even a UTF-8 BOM).[1] Files that use the tab character instead of comma can be more precisely referred to as "TSV" for tab-separated values.
Other implementation differences include handling of more commonplace field separators (such as space or semicolon) and newline characters inside text fields. One more subtlety is the interpretation of a blank line: it can equally be the result of writing a record of zero fields, or a record of one field of zero length; thus decoding it is ambiguous.
Reliance on the standard documented by RFC 4180 can simplify CSV exchange. However, this standard only specifies handling of text-based fields. Interpretation of the text of each field is still application-specific.
RFC 4180 formalized CSV. It defines the MIME type "text/csv", and CSV files that follow its rules should be very widely portable. Among its requirements: MS-DOS-style lines that end with (CR/LF) characters (optional for the last line). An optional header record (there is no sure way to detect whether it is present, so care is required when importing). Each record "should" contain the same number of comma-separated fields. Any field may be quoted (with double quotes). Fields containing a line-break, double-quote or commas should be quoted. (If they are not, the file will likely be impossible to process correctly). A (double) quote character in a field must be represented by two (double) quote characters.
The format can be processed by most programs that claim to read CSV files. The exceptions are: (a) programs may not support line-breaks within quoted fields, (b) programs may confuse the optional header with data or interpret the first data line as an optional header and (c) double quotes in a field may not be parsed correctly automatically.
In 2011 Open Knowledge and various partners created a data protocols working group, which later evolved into the Frictionless Data initiative. One of the main formats they released was Tabular Data Package. Tabular Data package was heavily based on CSV, using it as the main data transport format and adding basic type and schema metadata (CSV lacks any type information to distinguish the string "1" from the number 1). An initial v1 of Tabular Data Package was released in 2015, and after extensive real-world testing and tool development, v1 of a CSV-based Tabular Data Package was officially released in September 2017.[14] The Frictionless Data Initiative has also provided a standard CSV Dialect Description Format for describing different dialects of CSV, for example specifying the field separator or quoting rules.
In 2013 the W3C "CSV on the Web" working group began to specify technologies providing a higher interoperability for web applications using CSV or similar formats.[15] The working group completed its work in February 2016, and is officially closed in March 2016 with the release of a set documents and W3C recommendations[16] for modeling "Tabular Data",[17] and enhancing CSV with metadata and semantics.
Many informal documents exist that describe "CSV" formats. IETF RFC 4180 (summarized above) defines the format for the "text/csv" MIME type registered with the IANA.
Rules typical of these and other "CSV" specifications and implementations are as follows: CSV is a delimited data format that has fields/columns separated by the comma character and records/rows terminated by newlines. A CSV file does not require a specific character encoding, byte order, or line terminator format (some software does not support all line-end variations). A record ends at a line terminator. However, line-terminators can be embedded as data within fields, so software must recognize quoted line-separators (see below) in order to correctly assemble an entire record from perhaps multiple lines. All records should have the same number of fields, in the same order. Data within fields is interpreted as a sequence of characters, not as a sequence of bits or bytes (see RFC 2046, section 4.1). For example, the numeric quantity 65535 may be represented as the 5 ASCII characters "65535" (or perhaps other forms such as "0xFFFF", "000065535.000E+00", etc.); but not as a sequence of 2 bytes intended to be treated as a single binary integer rather than as two characters (e.g. the numbers 11264-11307 have a comma as their high order byte: ord(,)*256..ord(,)*257-1). If this "plain text" convention is not followed, then the CSV file no longer contains sufficient information to interpret it correctly, the CSV file will not likely survive transmission across differing computer architectures, and will not conform to the text/csv MIME type. Adjacent fields must be separated by a single comma. However, "CSV" formats vary greatly in this choice of separator character. In particular, in locales where the comma is used as a decimal separator, semicolon, TAB, or other characters are used instead. 1997,Ford,E350
Any field may be quoted (that is, enclosed within double-quote characters). Some fields must be quoted, as specified in following rules.
"1997","Ford","E350"Fields with embedded commas or double-quote characters must be quoted.
1997,Ford,E350,"Super, luxurious truck"Each of the embedded double-quote characters must be represented by a pair of double-quote characters.
1997,Ford,E350,"Super, ""luxurious"" truck"Fields with embedded line breaks must be quoted (however, many CSV implementations do not support embedded line breaks).
1997,Ford,E350,"Go get one now they are going fast"In some CSV implementations[which?], leading and trailing spaces and tabs are trimmed (ignored). Such trimming is forbidden by RFC 4180, which states "Spaces are considered part of a field and should not be ignored." 1997, Ford, E350 not same as
1997,Ford,E350According to RFC 4180, spaces outside quotes in a field are not allowed; however, the RFC also says that "Spaces are considered part of a field and should not be ignored." and "Implementors should be conservative in what you do, be liberal in what you accept from others (RFC 793 [8]) when processing CSV files."

Main article: CSV application support
The CSV file format is supported by almost all spreadsheets and database management systems. Many programming languages have libraries available that support CSV files. Many implementations support changing the field-separator character and some quoting conventions, although it is safest to use the simplest conventions, to maximize the recipients chances of handling the data.
Microsoft Excel will open .csv files, but depending on the systems regional settings, it may expect a semicolon as a separator instead of a comma, since in some languages the comma is used as the decimal separator. Excel supports the use of a "sep= " row at the beginning of the file to change the expected delimiter (example: sep=; will cause Excel to use ";" as the delimiter). Excel also applies some additional data manipulations, such as reformatting what looks like numbers or dates, eliminating leading + or 0, which breaks phone numbers, or a leading = makes the cell a formula, where function names must be in the openers local language. Also, many regional versions of Excel will not be able to deal with Unicode in CSV. One simple solution when encountering such difficulties is to change the filename extension from .csv to .txt; then opening the file from an already running Excel instance with the "Open" command, where the user can manually specify the delimiters, encoding, format of columns, etc.
Apache OpenOffice Calc and LibreOffice Calc handle CSV files and pasted text with a Text Import dialog asking the user to manually specify the delimiters, encoding, format of columns, etc.
Numbers (spreadsheet), the Apple equivalent of Microsoft Excel, supports import and export of CSV files as well. In fact, this feature is one that can be expected on almost any spreadsheet editing program.
There are many utility programs on Unix-style systems that can deal with at least some CSV files. Many such utilities have a way to change the delimiter character, but lack support for any other variations (or for Unicode). Some of the useful programs are:
column (-s to change the delimiter character(s)) cut (-d to change the delimiter character) paste (-d to change the delimiter character(s)) join (-t to change the delimiter character) sort (-t to change the delimiter character) uniq (-f to skip comparing the first N fields) emacs (using csv-nav mode) awk (-F to change the delimiter character)

GETCIFSACL(1) CIFS Access Control List Tools GETCIFSACL(1) NAME getcifsacl - Userspace helper to display an ACL in a security descriptor for Common Internet File System (CIFS) SYNOPSIS getcifsacl [-v|-r] {file system object} DESCRIPTION This tool is part of the cifs-utils suite. getcifsacl is a userspace helper program for the Linux CIFS client file system. It is intended to display a security descriptor including ACL for a file system object. It is best utilized when an option of cifsacl is specified when mounting a cifs share in conjunction with winbind facility of Samba suite. Fields of an ACE such as SID, type, flags, and mask are displayed separated by /. Numeric values of type, flags, and mask are displayed in hexadecimal format. OPTIONS -v Print version number and exit. -r Display a security descriptor in raw mode. Values such as type and flags are displayed in hexadecimal format, a SID is not mapped to a name. NOTES Kernel support for getcifsacl/setcifsacl utilities was initially introduced in the 2.6.37 kernel. SEE ALSO mount.cifs(8), winbindd(8), setcifsacl(1) AUTHOR Shirish Pargaonkar wrote the getcifsacl program. The Linux CIFS Mailing list is the preferred place to ask questions regarding these programs. cifs-utils 08/19/2011 GETCIFSACL(1)

MERGE_RECURSIVE(document1, document2, ... documentN) → mergedDocument
Recursively merge the documents document1 to documentN into a single document. If document attribute keys are ambiguous, the merged result will contain the values of the documents contained later in the argument list.
For example, two documents with distinct attribute names can easily be merged into one:
MERGE_RECURSIVE(
{ "user-1": { "name": "Jane", "livesIn": { "city": "LA" } } },
{ "user-1": { "age": 42, "livesIn": { "state": "CA" } } }
)
// { "user-1": { "name": "Jane", "livesIn": { "city": "LA", "state": "CA" }, "age": 42 } }
MERGE_RECURSIVE() does not support the single array parameter variant that MERGE offers.


Filter
The GridControl provides a set of filtering options that simplify data management. This demo illustrates how to specify a filter expression using the grid’s FilterString property. The specified filter is displayed in the filter panel that is automatically shown at the bottom of the grid after a filter has been applied. This panel contains buttons allowing end-users to disable/enable and clear the filter.

Instance Attribute Details
#destroyed? ⇒ Boolean
(readonly)
Returns true if this object has been destroyed, otherwise returns false.
# File 'activerecord/lib/active_record/persistence.rb', line 237
def destroyed? sync_with_transaction_state @destroyed end
#new_record? ⇒ Boolean
(readonly)
Returns true if this object hasn’t been saved yet – that is, a record for the object doesn’t exist in the database yet; otherwise, returns false.

Returns true if the record is persisted, i.e. it’s not a new record and it was not destroyed, otherwise returns false.

def persisted? sync_with_transaction_state !(@new_record || @destroyed) end
Instance Method Details
#becomes(klass)
Returns an instance of the specified klass
with the attributes of the current record. This is mostly useful in relation to single-table inheritance structures where you want a subclass to appear as the superclass. This can be used along with record identification in Action Pack to allow, say, Client < Company
to do something like render partial: @client.becomes(Company)
to render that instance using the companies/company partial instead of clients/client.
Note: The new instance will share a link to the same attributes as the original class. Therefore the sti column value will still be the same. Any change to the attributes on either instance will affect both instances. If you want to change the sti column as well, use #becomes! instead.
# File 'activerecord/lib/active_record/persistence.rb', line 372

#becomes!(klass)
Wrapper around #becomes that also changes the instance’s sti column value. This is especially useful if you want to persist the changed class in your database.
Note: The old instance’s sti column value will be changed too, as both objects share the same set of attributes.
# File 'activerecord/lib/active_record/persistence.rb', line 390
def becomes!(klass) became = becomes(klass) sti_type = nil if !klass.descends_from_active_record? sti_type = klass.sti_name end became.public_send("#{klass.inheritance_column}=", sti_type) became end
#decrement(attribute, by = 1)
Initializes attribute
to zero if nil
and subtracts the value passed as by
(default is 1). The decrement is performed directly on the underlying attribute, no setter is invoked. Only makes sense for number-based attributes. Returns self
.
# File 'activerecord/lib/active_record/persistence.rb', line 515
def decrement(attribute, by = 1) increment(attribute, -by) end
#decrement!(attribute, by = 1, touch: nil)
Wrapper around #decrement that writes the update to the database. Only attribute
is updated; the record itself is not saved. This means that any other modified attributes will still be dirty. Validations
and callbacks are skipped. Supports the #touch option from update_counters
, see that for more. Returns self
.
# File 'activerecord/lib/active_record/persistence.rb', line 525
def decrement!(attribute, by = 1, touch: nil) increment!(attribute, -by, touch: touch) end
#delete
Deletes the record in the database and freezes this instance to reflect that no changes should be made (since they can’t be persisted). Returns the frozen instance.
The row is simply removed with an SQL DELETE
statement on the record’s primary key, and no callbacks are executed.
Note that this will also delete records marked as #readonly?.
To enforce the object’s before_destroy
and after_destroy
callbacks or any :dependent
association options, use #destroy.
# File 'activerecord/lib/active_record/persistence.rb', line 323
def delete _delete_row if persisted? @destroyed = true freeze end
#destroy
Deletes the record in the database and freezes this instance to reflect that no changes should be made (since they can’t be persisted).
There’s a series of callbacks associated with #destroy
. If the before_destroy
callback throws :abort
the action is cancelled and #destroy
returns false
. See Callbacks
for further details.
# File 'activerecord/lib/active_record/persistence.rb', line 336
def destroy _raise_readonly_record_error if readonly? destroy_associations self.class.connection.add_transaction_record(self) @_trigger_destroy_callback = if persisted? destroy_row > 0 else true end @destroyed = true freeze end
#destroy!
Deletes the record in the database and freezes this instance to reflect that no changes should be made (since they can’t be persisted).
There’s a series of callbacks associated with #destroy!
. If the before_destroy
callback throws :abort
the action is cancelled and #destroy!
raises RecordNotDestroyed
. See Callbacks
for further details.
# File 'activerecord/lib/active_record/persistence.rb', line 356
def destroy! destroy || _raise_record_not_destroyed end
#increment(attribute, by = 1)
Initializes attribute
to zero if nil
and adds the value passed as by
(default is 1). The increment is performed directly on the underlying attribute, no setter is invoked. Only makes sense for number-based attributes. Returns self
.
# File 'activerecord/lib/active_record/persistence.rb', line 492
def increment(attribute, by = 1) self[attribute] ||= 0 self[attribute] += by self end
#increment!(attribute, by = 1, touch: nil)
Wrapper around #increment that writes the update to the database. Only attribute
is updated; the record itself is not saved. This means that any other modified attributes will still be dirty. Validations
and callbacks are skipped. Supports the #touch option from update_counters
, see that for more. Returns self
.
# File 'activerecord/lib/active_record/persistence.rb', line 504
def increment!(attribute, by = 1, touch: nil) increment(attribute, by) change = public_send(attribute) - (attribute_in_database(attribute.to_s) || 0) self.class.update_counters(id, attribute => change, touch: touch) clear_attribute_change(attribute) # eww self end
#reload(options = nil)
Reloads the record from the database.
This method finds the record by its primary key (which could be assigned manually) and modifies the receiver in-place:
account = Account.new
# => #<Account id: nil, email: nil>
account.id = 1
account.reload
# Account Load (1.2ms) SELECT "accounts".* FROM "accounts" WHERE "accounts"."id" = $1 LIMIT 1 [["id", 1]]
# => #<Account id: 1, email<EMAIL_ADDRESS>Attributes
are reloaded from the database, and caches busted, in particular the associations cache and the QueryCache
.
If the record no longer exists in the database RecordNotFound
is raised. Otherwise, in addition to the in-place modification the method returns self
for convenience.
The optional :lock
flag option allows you to lock the reloaded record:
reload(lock: true) # reload with pessimistic locking
Reloading is commonly used in test suites to test something is actually written to the database, or when some action modifies the corresponding row in the database but not the object in memory:
assert account.deposit!(25)
assert_equal 25, account.credit # check it is updated in memory
assert_equal 25, account.reload.credit # check it is also persisted
Another common use case is optimistic locking handling:
def with_optimistic_retry
begin
yield
rescue ActiveRecord::StaleObjectError
begin
# Reload lock_version in particular.
reload
rescue ActiveRecord::RecordNotFound
# If the record is gone there is nothing to do.
else
retry
end
end

#save(*args)
Saves the model.
If the model is new, a record gets created in the database, otherwise the existing record gets updated.
By default, save always runs validations. If any of them fail the action is cancelled and #save
returns false
, and the record won’t be saved. However, if you supply validate: false
, validations are bypassed altogether. See Validations
for more information.
By default, #save
also sets the updated_at
/updated_on
attributes to the current time. However, if you supply touch: false
, these timestamps will not be updated.
There’s a series of callbacks associated with #save
. If any of the before_*
callbacks throws :abort
the action is cancelled and #save
returns false
. See Callbacks
for further details.
Attributes
marked as readonly are silently ignored if the record is being updated.
# File 'activerecord/lib/active_record/persistence.rb', line 274

#save!(*args)
Saves the model.
If the model is new, a record gets created in the database, otherwise the existing record gets updated.
By default, #save!
always runs validations. If any of them fail RecordInvalid
gets raised, and the record won’t be saved. However, if you supply validate: false
, validations are bypassed altogether. See Validations
for more information.
By default, #save!
also sets the updated_at

raises RecordNotSaved
. See Callbacks

#toggle(attribute)
Assigns to attribute
the boolean opposite of attribute?
. So if the predicate returns true
the attribute will become false
. This method toggles directly the underlying value without calling any setter. Returns self
.
Example:
user = User.first
user.banned? # => false
user.toggle(:banned)
user.banned? # => true
# File 'activerecord/lib/active_record/persistence.rb', line 541
def toggle(attribute) self[attribute] = !public_send("#{attribute}?") self end
#toggle!(attribute)
Wrapper around #toggle that saves the record. This method differs from its non-bang version in the sense that it passes through the attribute setter. Saving is not subjected to validation checks. Returns true
if the record could be saved.
# File 'activerecord/lib/active_record/persistence.rb', line 550
def toggle!(attribute) toggle(attribute).update_attribute(attribute, self[attribute]) end
#touch(*names, time: nil)
Saves the record with the updated_at/on attributes set to the current time or the time specified. Please note that no validation is performed and only the after_touch
, after_commit
and after_rollback
callbacks are executed.
This method can be passed attribute names and an optional time argument. If attribute names are passed, they are updated along with updated_at/on attributes. If no time argument is passed, the current time is used as default.
product.touch # updates updated_at/on with current time
product.touch(time: Time.new(2015, 2, 16, 0, 0, 0)) # updates updated_at/on with specified time
product.touch(:designed_at) # updates the designed_at attribute and updated_at/on
product.touch(:started_at, :ended_at) # updates started_at, ended_at and updated_at/on attributes
If used along with belongs_to then touch
will invoke touch
method on associated object.
class Brake < ActiveRecord::Base
belongs_to :car, touch: true
end
class Car < ActiveRecord::Base
belongs_to :corporation, touch: true
end
# triggers @brake.car.touch and @brake.car.corporation.touch
@brake.touch
Note that touch
must be used on a persisted object, or else an ActiveRecordError
will be thrown. For example:
ball = Ball.new
ball.touch(:updated_at) # => raises ActiveRecordError
# File 'activerecord/lib/active_record/persistence.rb', line 651
def touch(*names, time: nil) unless persisted? raise ActiveRecordError, <<-MSG.squish cannot touch on a new or destroyed record object. Consider using persisted?, new_record?, or destroyed? before touching MSG end attribute_names = attribute_names |= names.map(&:to_s) unless attribute_names.empty? affected_rows = _touch_row(attribute_names, time) @_trigger_update_callback = affected_rows == 1 else true end end
#update(attributes) Also known as: #update_attributes
Updates the attributes of the model from the passed-in hash and saves the record, all wrapped in a transaction. If the object is invalid, the saving will fail and false will be returned.
# File 'activerecord/lib/active_record/persistence.rb', line 423
def update(attributes) # The following transaction covers any possible database side-effects of the # attributes assignment. For example, setting the IDs of a child collection. with_transaction_returning_status do assign_attributes(attributes) save end end
#update!(attributes) Also known as: #update_attributes!
# File 'activerecord/lib/active_record/persistence.rb', line 436
def update!(attributes) # The following transaction covers any possible database side-effects of the # attributes assignment. For example, setting the IDs of a child collection. with_transaction_returning_status do assign_attributes(attributes) save! end end
#update_attribute(name, value)
Updates a single attribute and saves the record. This is especially useful for boolean flags on existing records. Also note that
-
Validation is skipped.
-
Callbacks are invoked.
-
updated_at/updated_on column is updated if that column is available.
-
Updates all the attributes that are dirty in this object.
This method raises an ActiveRecordError
if the attribute is marked as readonly.
Also see #update_column.
# File 'activerecord/lib/active_record/persistence.rb', line 412
def update_attribute(name, value) name = name.to_s verify_readonly_attribute(name) public_send("#{name}=", value) save(validate: false) end
#update_attributes(attributes)
Alias for #update.
# File 'activerecord/lib/active_record/persistence.rb', line 432
alias update_attributes update
#update_attributes!(attributes)
Alias for #update!.
# File 'activerecord/lib/active_record/persistence.rb', line 445
alias update_attributes! update!
#update_column(name, value)
Equivalent to update_columns(name => value)
.
# File 'activerecord/lib/active_record/persistence.rb', line 448
def update_column(name, value) update_columns(name => value) end
#update_columns(attributes)
Updates the attributes directly in the database issuing an UPDATE SQL statement and sets them in the receiver:
user.update_columns(last_request_at: Time.current)
This is the fastest way to update attributes because it goes straight to the database, but take into account that in consequence the regular update procedures are totally bypassed. In particular:
-
Validations are skipped.
-
Callbacks are skipped.
-
updated_at
/updated_on
are not updated. -
However, attributes are serialized with the same rules as Relation#update_all
This method raises an ActiveRecordError
when called on new objects, or when at least one of the attributes is marked as readonly.
# File 'activerecord/lib/active_record/persistence.rb', line 468
