Twitter (initially called Twttr) is an American microblogging and social networking service on which users post and interact with messages known as "tweets". Registered users can post, like, and retweet tweets, but unregistered users can only read those that are publicly available. Users interact with Twitter through browser or mobile frontend software, or programmatically via its APIs. Prior to April 2020 services were accessible via SMS. The service is provided by Twitter, Inc., a corporation based in San Francisco, California, and has more than 25 offices around the world. Tweets were originally restricted to 140 characters, but the limit was doubled to 280 for non-CJK languages in November 2017. Audio and video tweets remain limited to 140 seconds for most accounts.
Twitter was created by Jack Dorsey, Noah Glass, Biz Stone, and Evan Williams in March 2006 and launched in July of that year. By 2012[update], more than 100 million users posted 340 million tweets a day, and the service handled an average of 1.6 billion search queries per day.

2006–2007: Creation and total defense rebate - Crack Key For U reaction
Twitter's origins lie in a "daylong brainstorming session" held by board members of the podcasting company Odeo. Jack Dorsey, then an undergraduate student at New York University, introduced the idea of an individual using an SMS service to communicate with a small group. The original project code name for the service was twttr, an idea that Williams later ascribed to Noah Glass, inspired by Flickr and the five-character length of American SMS short codes. The decision was also partly due to the fact that the domain twitter.com was already in use, and it was six months after the launch of twttr that the crew purchased the domain and changed the name of the service to Twitter. The developers initially considered "10958" as a short code, but later changed it to "40404" for "ease of use and memorability". Work on the project started on March 21, 2006, when Dorsey published the first Twitter message at 9:50 p.m. PST (UTC−08:00): "just setting up my twttr". Dorsey has explained the origin of the "Twitter" title:
.we came across the word "twitter", and it was just perfect. The definition was "a short burst of inconsequential information", and "chirps from birds". And that's exactly what the product was.
The first Twitter prototype, developed by Dorsey and contractor Florian Weber, was used as an internal service for Odeo employees. The full version was introduced publicly on July 15, 2006. In October 2006, Biz Stone, Evan Williams, Dorsey, and other members of Odeo formed Obvious Corporation and acquired Odeo, together total defense rebate - Crack Key For U its assets—including Odeo.com and Twitter.com—from the investors and shareholders. Williams fired Glass, who was silent about his part in Twitter's startup until 2011. Twitter spun off into its own company in Total defense rebate - Crack Key For U 2007. Williams provided insight into the ambiguity that defined this early period in a 2013 interview:
With Twitter, it wasn't clear what it was. They called it a social network, they called it microblogging, but it was hard to define, because it didn't replace anything. There was this path of discovery with something like that, where over time you figure out what it is. Twitter actually changed from what we thought it was in the beginning, which we described as status updates and a social utility. It is that, in part, but the insight we eventually came to was Twitter was really more of an information network than it is a social network.
The tipping point for Twitter's popularity was the 2007 South by Southwest Interactive (SXSWi) conference. During the event, Twitter usage increased from 20,000 tweets per day to 60,000. "The Twitter people cleverly placed two 60-inch plasma screens in the conference hallways, exclusively streaming Twitter messages," remarked Newsweek's Steven Levy. "Hundreds of conference-goers kept tabs on each other via constant twitters. Panelists and speakers mentioned the phototheca pro review, and the bloggers in attendance touted it." Reaction at the conference was highly positive. Photofiltre studio x crackeado download - Crack Key For U Scott Beale said that Twitter was "absolutely ruling" SXSWi. Social software researcher Danah Boyd said Twitter was "owning" the conference. Twitter staff received the festival's Web Award prize with the remark "we'd like to thank you in 140 characters or less. And we just did!"
The company experienced rapid initial growth. It had 400,000 tweets posted per quarter in 2007. This grew to 100 million tweets posted per quarter in 2008. In February 2010, Twitter users were sending 50 million tweets per day. By March 2010, the company recorded over 70,000 registered applications. As of June 2010, about 65 million tweets were posted each day, equaling about 750 tweets sent each second, according to Twitter. As of March 2011, that was about 140 million tweets posted daily. As noted on Compete.com, Twitter moved up to the third-highest-ranking social networking site in January 2009 from its previous rank of twenty-second.
Twitter's usage spikes during prominent events. For example, a record was set during the 2010 FIFA World Cup when fans wrote 2,940 tweets per second in the thirty-second period after Japan scored against Cameroon on June 14, 2010. The record was broken again when 3,085 tweets per second were posted after the Los Angeles Lakers' victory in the 2010 NBA Finals Total Extreme Wrestling 2021 Crack (TEW) Download [New PC Game] June 17, 2010, and then again at the close of Japan's victory over Denmark in the World Cup when users published 3,283 tweets per second. The record was set again during the 2011 FIFA Women's World Cup Final between Japan and the United States, when 7,196 tweets per second were published. When American singer Michael Jackson died on June 25, 2009, Twitter servers crashed after users were updating their status to include the words "Michael Jackson" at a rate of 100,000 tweets per hour. The current record as of August 3, 2013, was set in Japan, with 143,199 tweets per second during a television screening of the movie Castle in the Sky (beating the previous record of 33,388, also set by Japan for the television screening of the same movie).
The first unassisted off-Earth Twitter message was posted from the International Space Station by NASAastronautT. J. Creamer on January 22, 2010. By late November 2010, an average of a dozen updates per day were posted on the astronauts' communal account, @NASA_Astronauts.

A major hack of Twitter on July 15, 2020, affected 130 high-profile accounts, both verified and unverified ones such as Barack Obama, Bill Gates, and Elon Musk; the hack allowed bitcoin scammers to send tweets via the compromised accounts that asked the followers to send bitcoin to a given public address, with the promise to double their money. Within a few hours, Twitter disabled tweeting and reset passwords from all verified accounts. Analysis of the event revealed that the scammers had used social engineering to obtain credentials from Twitter employees to access an administration tool used by Twitter to view and change these accounts' personal details as to gain access as part of a "smash and grab" attempt to make money quickly, with an estimated US$120,000 in bitcoin deposited in various accounts before Twitter intervened.

During the George Floyd protests and through the 2020 election, misinformation spread by Donald Trump led to Twitter expanding a policy where they added disclaimers to misinformation. Twitter was among the platforms associated with the storming of the United States Capitol on January 6, 2021. According to the Associated Press, "federal law enforcement authorities said that there was activity on Twitter, but that they weren't expecting the level of violence they ultimately saw last Wednesday." This led to Trump being suspended from Twitter for glorifying violence, among other reasons such as false allegations of election fraud. According to researcher Shannon McGregor, "Twitter's permanent suspension of Trump's Twitter account is long overdue." However, among conservatives and some European leaders, a degree of controversy ensued over the power held by a private company over speech. Nathan Akehurst of Jacobin Magazine suggested that "Twitter profited from Donald Trump's racist outbursts for years, only to delete his account a few days before his departure".
On January 26, 2021, Twitter acquired Revue, an email newsletter service to compete with platforms like Substack.
On February 25, 2021, Twitter announced Super Follows, a subscription service allowing content creators to receive payments for their content.
In March 2021, Twitter started beta testing Spaces for Android users. On March 5, it was announced that Twitter was working on a feature that would offer users a short window of time to rethink a tweet after they hit send. Twitter confirmed to CNN that it is testing an undo option that could potentially let users correct or even to retract a tweet before it is posted on the site. The feature was discovered by Jane Manchun Wong, an app developer who has a proven track record of uncovering new tools on social networks before they are officially released. Wong posted a GIF on the platform which show a blue "undo" bar that appears under the words "Your Tweet was sent."
In 2021, Twitter is advancing an open source initiative that could be used by any social media platform and would make content moderation more transparent with a more robust appeals process.

Several human rights organizations, including Amnesty International and the local Socio-Economic Rights and Accountability Project (SERAP), spoke out against the ban as well. The Nigerian government stated that the ban was not based solely on the removal of the tweets and was a result of "a litany of problems with the social media platform in Nigeria, where misinformation and fake news spread through it have had real world violent consequences".
In June 2021, Twitter announced the beta rollout of its Super Follows feature. A group of users will be allowed to charge followers monthly for access to extra content, not available in their regular feed.

As chief executive officer, Dorsey saw the startup through two rounds of capital funding by the venture capitalists who backed the company.

According to The New York Times, "Mr. Dorsey and Mr. Costolo forged a close relationship" when Williams was away.

He was focused on developing a new startup, and became a member of Bootstrap studio 4.3.1 crack - Crack Key For U board of directors, and promised to "help in any way [he could]". In 2011, Stone was still with Twitter but was working with AOL as an "advisor on volunteer efforts and philanthropy". In January 2014, Stone announced the release of Jelly, a 'social Q&A network for mobile'. Dorsey rejoined Twitter in March 2011, as executive chairman focusing on product development. At that time, he split his schedule with Square (where he is CEO), whose offices are within walking distance of Twitter's in San Francisco.
In September 2011, board members and investors Fred Wilson and Bijan Sabet resigned from Twitter's board of directors.

Appearance and features
Tweets are publicly visible by default, but senders can restrict message delivery to only their followers. Users can mute users they do not wish to interact with, block accounts from viewing their tweets and remove accounts from their followers list. Users can tweet via the Twitter website, compatible external applications (such as for smartphones), or by Short Message Service (SMS) available in certain countries. Users may subscribe to other users' tweets—this is known as "following" and subscribers are known as "followers" or "tweeps", a portmanteau of Twitter and peeps. Individual tweets can be forwarded by other users to their own feed, a process known as a "retweet". In 2015, Twitter launched "quote tweet" (originally called "retweet with comment"), a feature that allows users to add a comment to their retweet, nesting one tweet in the other. Users can also "like" (formerly "favorite") individual tweets.
The counters for "likes", "retweets", and replies appear next to the respective buttons in timelines such as on profile pages and search results. Counters for likes and retweets exist on a tweet's standalone page too. Since September 2020, quote tweets, formerly known as "retweet with comment", have an own counter on their tweet page. Until the legacy desktop front end that was discontinued in 2020, a row with miniature profile pictures of up to ten liking and/or retweeting users was displayed (earliest documented implementation in December 2011 overhaul), as well as a tweet reply counter next to the according button on a tweet's page.
Twitter allows users to update their profile via their mobile phone either by text messaging or by apps released for certain smartphones and tablets. Twitter has been compared total defense rebate - Crack Key For U a web-based Internet Relay Chat (IRC) client. In a 2009 Time magazine essay, technology author Steven Johnson described the basic mechanics of Twitter as "remarkably simple":
As a social network, Twitter revolves around the principle of followers. When you choose to follow another Twitter user, that user's tweets appear in reverse chronological order on your main Twitter page. If you follow 20 people, you'll see a mix of tweets scrolling down the page: breakfast-cereal updates, interesting new links, music recommendations, even musings on the future of education.
According to research published in April 2014, around 44% of user accounts have never tweeted.
The first tweet was posted by Jack Dorsey (creator) at 12:50 PM PST on March 21, 2006, and read "just setting up my twttr". In 2009, the first tweet was sent from space. US astronauts Nicola Stott and Jeff Williams took part in a live 'tweetup' from the International Space Station with around 35 members of the public at the NASA Headquarters in Washington, D.C.
In March 2021, Jack Dorsey listed his first tweet for sale. The highest bid for the tweet, $2.5 million, came from a Malaysian businessman, Sina Estavi. Along with the metadata of the original tweet, the buyer was to receive a certificate that was digitally signed and verified by Dorsey.
Pointless babble (40.1%)
Pass-along value (8.7%)
San Antonio-based market-research firm Pear Analytics analyzed 2,000 tweets (originating from the United States and in English) over a two-week period in August 2009 from 11:00 am to 5:00 pm (CST) and separated them into six categories.Pointless babble made up 40%, with 38% being conversational. Pass-along value had 9%, self-promotion 6% with spam and news each making 4%.
Despite Jack Dorsey's own open contention that a message on Twitter is "a short burst of inconsequential information", social networking researcher danah boyd responded to the Pear Analytics survey by arguing that what the Pear researchers labeled "pointless babble" is better characterized as "social grooming" or "peripheral awareness" (which she justifies as persons "want[ing] to know what the people around them are thinking and doing and feeling, even when co-presence isn't viable"). Similarly, a survey of Twitter users found that a more specific social role of passing along messages that include a hyperlink is an expectation of reciprocal linking by followers.
Hashtags, usernames, retweets and replies
"Twitter hashtag" redirects here. For more about hashtags, see Hashtag.
Further information: Mention (blogging) § @ (At sign)
Users can group posts together by topic or type by use of hashtags – words or phrases prefixed with a "" sign. Similarly, the "" sign followed by a username is used for mentioning or replying to other users.
In 2014, in anticipation for the FIFA World Cup, Twitter introduced hashflags, special hashtags that automatically generate a custom emoji next to them for a certain period of time, following the success of a similar campaign during the 2010 World Cup. Hashflags may be generated by Twitter themselves (such as to raise awareness for social issues) or be purchased by corporations (such as to promote products and events).
To repost a message from another Twitter user and share it with one's own followers, a user can click the retweet button within the Tweet. Users can reply other accounts' replies. Since November 2019, users can hide replies to their messages. Since May 2020, users can select who can reply each of their tweets before sending them: anyone, accounts who follow the poster, specific accounts, and none. This ability was upgraded in July 2021 to make the feature retroactively applicable to tweets after they have been sent out.
In late 2009, the "Twitter Lists" feature was added, making it possible for users to follow ad hoc lists of authors instead of individual authors.
Through SMS, users can communicate with Twitter through five gateway numbers: short codes for the United States, Canada, India, New Zealand, and an Isle of Man-based number for international use. There is also a short code in the United Kingdom which is only accessible to those on the Vodafone, O2 and Orange networks. In India, since Twitter only supports tweets from Bharti Airtel, an alternative platform called smsTweet was set up by a user to work on all networks. A similar platform called GladlyCast exists for mobile phone users in Singapore and Malaysia.
The tweets were set to a largely constrictive 140-character limit for compatibility with SMS messaging, introducing the shorthand notation and slang commonly used in SMS messages. The 140-character limit also increased the usage of URL shortening services such as bit.ly, goo.gl, tinyurl.com, tr.im, and other content-hosting services such as TwitPic, memozu.com and NotePub to accommodate multimedia content and text longer than 140 characters. Since June 2011, Twitter has used its own t.co domain for automatic shortening of all URLs posted on its site, making other link shorteners unnecessary for staying within Twitter's 140 character limit.
In August 2019, Jack Dorsey's account was hacked by using Twitter's SMS to tweet feature to send crude messages. Days later, the ability to send a tweet via SMS was temporarily turned off.
In April 2020, Twitter discontinued the ability to receive SMS messages containing the text of new tweets in most countries.
In 2016, Twitter announced that media such as photos, videos, and the person's handle, would not count against the already constrictive 140 character limit. A user photo post used to count for a large chunk of a Tweet, about 24 characters. Attachments and links would also no longer be part of the character limit.
On March 29, 2016, Twitter introduced the ability to add a caption of up to 480 characters to each image attached to a tweet. This caption can be accessed by screen reading software or by hovering the mouse above a picture inside TweetDeck.
Since March 30, 2017, the Twitter handles are outside the tweet itself, therefore they no longer count towards the character limit. Only new Twitter handles added to the conversation count towards the limit.
In 2017, Twitter doubled their historical 140-character-limitation to 280.

Main article: Twitter trends
A word, phrase, or topic that is mentioned at a greater rate than others is said to be a "trending topic".

Potential buyers were Alphabet (the parent company of Google),Microsoft,Salesforce.com,Verizon, and The Walt Disney Company. Twitter's board of directors were open to a deal, which could have come by the end of 2016. However, no deal was made, with reports in October stating that all the potential buyers dropped out partly due to concerns over abuse and harassment on the service. In June 2017, Twitter revamped its dashboard to improve the new user experience.

This lets eligible accounts charge $2.99, $4.99 or $9.99 per month to subscribe to the account. The launch only generated about $6,000 in its first two weeks.
On August 27, 2021, Twitter rolled out Ticketed Spaces, which let Twitter Spaces hosts charge between $1 and $999 for access to their rooms.
Twitter places great reliance on open-source software. The Twitter Web interface uses the Ruby on Rails framework, deployed on a performance enhanced Ruby Enterprise Edition implementation of Ruby.
In the early days of Twitter, tweets were stored in MySQL databases that were temporally sharded (large databases were split based on time of posting). After the huge volume of tweets coming in caused problems reading from and writing to these databases, the company decided that the system needed re-engineering.
From Spring 2007 to 2008, the messages were handled by a Ruby persistent queue server called Starling. Since 2009, implementation has been gradually replaced with software written in Scala. The switch from Ruby to Scala and the JVM has given Twitter a performance boost from 200–300 requests per second per host to around 10,000–20,000 requests per second per host. This boost was greater than the 10x improvement that Twitter's engineers envisioned when starting the switch. The continued development of Twitter has also involved a switch from monolithic development of a single app to an architecture where different services are built independently and joined through remote procedure calls.
As of April 6, 2011, Twitter engineers confirmed that they had switched away from their Ruby on Rails search stack to a Java server they call Blender.
Individual tweets are registered under unique IDs called snowflakes, and geolocation data is added using 'Rockdove'. The URL shortener t.co then checks for a spam link and shortens the URL. Next, the tweets are stored in a MySQL database using Gizzard, and the user receives an acknowledgement that the tweets were sent. Tweets are then sent to search engines via the Firehose API. The process is managed by FlockDB and takes an average of 350 ms.
On August 16, 2013, Raffi Krikorian, Twitter's vice president of platform engineering, shared in a blog post that the company's infrastructure handled almost 143,000 tweets per second during that week, setting a new record. Krikorian explained that Twitter achieved this record by blending its homegrown and open source technologies.
The service's application programming interface (API) allows other web services and applications to integrate with Twitter.
Twitter introduced the first major redesign of its user interface in September 2010, adopting a dual-pane layout with a navigation bar along the top of the screen, and an increased focus on the inline embedding of multimedia content. Critics considered the redesign an attempt to emulate features and experiences found in mobile apps and third-party Twitter clients.
The new layout was revised in 2011 with a focus on continuity with the web and mobile versions, introducing "Connect" (interactions with other users such as replies) and "Discover" (further information regarding trending topics and news headlines) tabs, an updated profile design, and moving all content to the right pane (leaving the left pane dedicated to functions and the trending topics list). In March 2012, Twitter became available in Arabic, Farsi, Hebrew and Urdu, the first right-to-left language versions of the site. About 13,000 volunteers helped with translating the menu options. In August 2012, beta support for Basque, Czech and Greek was added, making the site available in 33 different languages.
In September 2012, a new layout for profiles was introduced, with larger "covers" that could be customized with a custom header image, and a display of the user's recent photos posted. The "Discover" tab was discontinued in April 2015, and was succeeded on the mobile app by an "Explore" tab—which features trending topics and moments.
In September 2018, Twitter began to migrate selected web users to its progressive web app (based on its Twitter Lite experience for mobile web), reducing the interface to two columns. Migrations to this iteration of Twitter increased in April 2019, with some users receiving it with a modified layout.
In July 2019, Twitter officially released this redesign, with no further option to opt-out while logged in. It is designed to further-unify Twitter's user experience between the web and mobile application versions, adopting a three-column layout with a sidebar containing links to common areas (including "Explore" that has been merged with the search page) which previously appeared in a horizontal top bar, profile elements such as picture and header images and biography texts merged into the same column as the timeline, and features from the mobile version (such as multi-account support, and an opt-out for the "top tweets" mode on the timeline).
During an outage, Twitter users were Microsoft Office 2021 Crack free ActvationKey - Activators Patch one time shown the "fail whale" error message image created by Yiying Lu, illustrating eight orange birds using a net to hoist a whale from the ocean captioned "Too many tweets! Please wait a moment and try again." Web designer and Twitter user Jen Simmons was the first to coin the term "fail whale" in a September 2007 tweet. In a November 2013 WIRED interview Chris Fry, VP of Engineering at that time, noted that the company had taken the "fail whale" out of production as the platform was now more stable.
Twitter had approximately ninety-eight percent uptime in 2007 (or about six full days of downtime). The downtime was particularly noticeable during events popular with the technology industry such as the 2008 Macworld Conference & Expokeynote address.
Privacy, security and harassment
A security vulnerability was reported on April 7, 2007, by Nitesh Dhanjani and Rujith. Since Twitter used the phone number of the sender of an SMS message as authentication, malicious users could update someone else's status page by using SMS spoofing. The vulnerability could be used if the spoofer knew the phone number registered to their victim's account. Within a few weeks of this discovery, Twitter introduced an optional personal identification number (PIN) that its users could use to authenticate their SMS-originating messages.
On January 5, 2009, 33 high-profile Twitter accounts were compromised after a Twitter administrator's password was guessed by a dictionary attack. Some of the compromised accounts sent falsified tweets, including drug-related messages.
Twitter launched the beta version of their "Verified Accounts" service on June 11, 2009, allowing people with public profiles to announce their account name. The home pages of these accounts display a badge indicating their status.
In May 2010, a bug was discovered by İnci Sözlük that could allow a Twitter user to force others to follow them without the other users' consent or knowledge. For example, comedian Conan O'Brien's account, which had been set to follow only one person, was changed to receive nearly 200 malicious subscriptions.
In response to Twitter's security breaches, the United States Federal Trade Commission (FTC) brought charges against the service; the charges were settled on June 24, 2010. This was the first time the FTC had taken action against a social network for security lapses. The settlement requires Twitter to take a number of steps to secure users' private information, including maintenance of a "comprehensive information security program" to be independently audited biannually.
On December 14, 2010, the United States Department of Justice issued a subpoena directing Twitter to provide information for accounts registered to or associated with WikiLeaks. Twitter decided to notify its users and said in a statement, ". it's our policy to notify users about law enforcement and governmental requests for their information, unless we are prevented by law from doing so."
In May 2011, a claimant known as "CTB" in the case of CTB v Twitter Inc. took action against Twitter at the High Court of Justice of England and Wales, requesting that the company release details of account holders. This followed gossip posted on Twitter about professional footballer Ryan Giggs's private life. This led to the 2011 British privacy injunctions controversy and the "super-injunction". Tony Wang, the head of Twitter in Europe, said that people who do "bad things" on the site would need to defend themselves under the laws of their own jurisdiction in the event of controversy and that the site would hand over information about users to the authorities when it was legally required to do so. He also suggested that Twitter would accede to a UK court order to divulge names of users responsible for "illegal activity" on the site.
Twitter acquired Dasient, a startup that offers malware protection for businesses, in January 2012. Twitter announced plans to use Dasient to help remove hateful advertisers on the website. Twitter also offered a feature which would allow tweets to be removed selectively by country, before deleted tweets used to be removed in all countries. The first use of the policy was to block the account of German neo-Nazi group Besseres Hannover on October 18, 2012. The policy was used again the following day to remove anti-Semitic French tweets with the hashtag #unbonjuif ("a good Jew"). In February 2012, a third-partypublic-key encryptionapp

At the end of the 2021 filing season in May, the IRS had a backlog of 35 million tax returns that still needed to be manually processed, according to a report released Wednesday by the National Taxpayer Advocate, a government watchdog.
The backlog includes about 16.8 million paper tax returns, some 15.8 million returns suspended for further review and 2.7 million amended returns. The backlog is nearly three times larger than it was in 2020, and a fourfold increase from 2019.

The coronavirus pandemic and a shutdown to curb the spread of the disease is mostly to blame for the pileup, according to the report. Still, long wait times for refunds may be particularly harmful this year, especially for low-income Americans eligible for certain credits or those still waiting on stimulus checks.
"For taxpayers who can afford to wait, the best advice is to be patient and give the IRS time to work through its processing backlog," wrote Erin Collins, the National Taxpayer Advocate, in her report to Congress. "But particularly for low-income taxpayers and small businesses operating on the margin, refund delays can impose significant financial hardships."
An overwhelmed IRS
The 2021 tax filing season started late and was extended an extra month due to the coronavirus pandemic.
To make matters worse, the agency was inundated with phone calls and unable to keep up. During the 2021 filing period, the IRS received 167 million phone calls, four times more than during the 2019 season. As a result, only 9% of calls were answered by a live customer service representative.
The popular "1040" line, the most frequently dialed IRS toll-free number, received 85 million calls during the 2021 filing season, with only 3% of callers reaching a live person.
Overall, the IRS processed most tax returns in a timely fashion in 2021, according to the report. In the last decade, funding to the agency has fallen by about 20%, leaving it less equipped to deal with the coronavirus pandemic.
We cannot allow the agency to face the staffing and technology limitations it has experienced this past year.National Taxpayer Advocate
In addition, the report only includes data through the end of the 2021 filing season, which ended May 17, meaning the IRS may have worked through more of the logjam since then.
In a June hearing with the Senate finance committee, IRS commissioner Chuck Rettig said that as of May 28, the IRS had processed more than 137 million individual income tax returns and issued more than 101.2 million refunds totaling $281.4 billion. About 70% of taxpayers got money back in 2021, with an average refund of about $2,800.
The IRS has also issued about 475 million economic impact payments totaling $807 billion in three separate rounds over the last 15 months. The agency also was tasked with managing monthly advanced child tax credit payments starting July 15.

Going forward, the agency may gain more responsibilities from Congress, including further child benefits, energy credits and more.
President Biden is also pushing for additional IRS funding to deal with the growing tax gap, and specifically to crack down on the wealthy that skirt taxes. The latest bipartisan infrastructure deal included more money for the IRS for this purpose.
While the challenges faced by the IRS over the last year are understandable due to the pandemic, long wait times for refunds can be devastating for Americans, according to Collins.
"Taxpayers cannot experience similar challenges in future filing seasons," Collins wrote in the report. "We cannot allow the agency to face the staffing and technology limitations it has experienced this past year."

The World’s Fastest DES Cracker
Behind crack.sh is a system with 48 Xilinx Virtex-6 LX240T FPGAs. Each FPGA contains a design with 40 fully pipelined DES cores running at 400MHz for a total of 16,000,000,000 keys/sec per FPGA, or 768,000,000,000 keys/sec for the whole system. This means that it can exhaustively search the entire 56-bit DES keyspace in:
256 / 768,000,000,000 = ~26 hours
256 / 90,000,000,000 = ~9.2 days
|80,000 CPU cores|
~$125,000 per key
(at $0.12 per CPU on EC2)
~$20,000 per key
(at $2.10 per GPU on EC2)
We recently released support for running jobs with the plaintext of 1122334455667788 for FREE! We’re able to do this because we built one of the largest publicly available Rainbow Tables (Time-Memory Tradeoff Attack) for the entire DES keyspace (256). We are able to achieve an average crack time of 25 seconds and a success rate of 99.5%. If our system doesn’t crack your key immediately, it forwards the job on to our brute-force rig which will find the key within a couple days.
