Commercial aviation is the part of civil aviation that involves operating aircraft for hire to transport passengers or multiple loads of cargo. The Air Commerce Act of 1926 began to regularize commercial aviation by establishing standards and promotion. An Aeronautical Branch was established in the Department of Commerce with William P. MacCracken, Jr. as director. To promote commercial aviation, he told town fathers that "Communities without airports would be communities without airmail." Writing for Collier's in 1929, he noted "Commercial aviation is the first industry inspired by hero-worship and built upon heros". He cited the promotion in South America by Herbert Dargue in early 1927. After his trans-Atlantic flight, Charles Lindbergh made a tour of the 48 States paid for by the Guggenheim Foundation for the Promotion of Aeronautics. From that point commercial aviation took off: Roads were chocked on Sundays for weeks afterward, by motorists trying to get to Lambert Field, Lindbergh’s home port in Saint Louis, to buy their first air hop.
Hundreds of thousands of you went aloft for the first time that summer.” The Aeronautical Branch was charged with issuing commercial pilot licenses, airworthiness certificates, with investigating air accidents. After World War II, commercial aviation grew using ex-military aircraft to transport people and cargo; the experience used in designing heavy bombers such as the B-29 and Avro Lancaster could be used for designing heavy commercial aircraft. The DC-3 made for easier and longer commercial flights; the first commercial jet airliner to fly was the British de Havilland Comet. By 1952, the British state airline BOAC had introduced the Comet into scheduled service. While a technical achievement, the plane suffered a series of public failures, as the shape of the windows led to cracks due to metal fatigue; the fatigue was caused by cycles of pressurization and depressurization of the cabin, led to catastrophic failure of the plane's fuselage. By the time the problems were overcome, other jet airliner designs had taken to the skies.

Windows Error Reporting
Windows Error Reporting is a crash reporting technology introduced by Microsoft with Windows XP and included in Windows versions and Windows Mobile 5.0 and 6.0. Not to be confused with the Dr. Watson debugging tool which left the memory dump on the user's local machine, Windows Error Reporting collects and offers to send post-error debug information using the Internet to the Microsoft or stops responding on a user's desktop. No data is sent without the user's consent; when a dump reaches the Microsoft server, it is analyzed and a solution is sent back to the user when one is available. Solutions are served using Windows Error Reporting Responses. Windows Error Reporting runs as a Windows service and can optionally be disabled. If Windows Error Reporting itself crashes an error report that the original crashed process produced cannot be sent at all. Kinshuman is the original designer of Windows Error Reporting in Vista, the same design and implementation, present in current Windows versions. Microsoft first introduced Windows Error Reporting with Windows XP.
Windows Error Reporting was improved in Windows Vista. Most a new set of public APIs have been created for reporting failures other than application crashes and hangs. Developers can customize the reporting user interface; the new APIs are documented in MSDN. The architecture of Windows Error Reporting has been revamped with a focus on reliability and user experience. WER can now report errors when the process is in a bad state for example if the process has encountered stack exhaustions, PEB/TEB corruptions, heap corruptions, etc. In earlier OSs prior to Windows Vista, the process terminated silently without generating an error report in these conditions. A new Control Panel applet, "Problem Reports and Solutions" was introduced, keeping a record of system and application errors and issues, as well as presenting probable solutions to problems; the Problem Reports and Solutions Control Panel applet was replaced by the Maintenance section of the Windows Action Center on Windows 7 and Server 2008 R2.
A new app, Problem Steps Recorder, is available on all builds of Windows 7 and enables the collection of the actions performed by a user while encountering a crash so that testers and developers can reproduce the situation for analysis and debugging. WER is a distributed system. Client-side software detects an error condition, generates an error report, labels the bucket, reports the error to the WER service; the WER service records the error occurrence and depending on information known about the particular error, might request additional data from the client, or direct the client to a solution. Programmers access the WER service to retrieve data for specific error reports and for statistics-based debugging. Errors collected by WER clients are sent to the WER service; the WER service employs 60 servers connected to a 65TB storage area network that stores the error report database and a 120TB storage area network that stores up to 6 months of raw CAB files. The service is provisioned to receive and process well over 100 million error reports per day, sufficient to survive correlated global events such as Internet worms.
In the Microsoft Windows Error Reporting system, crash reports are organized according to "buckets". Buckets classify issues by: Application Name, Application Version, Application Build Date, Module Name, Module Version, Module Build Date, OS Exception Code/System Error Code, Module Code Offset. Ideally, each bucket contains crash reports. However, there are two forms of weakness in the WER bucketing: weaknesses in the condensing heuristics, which result in mapping reports from a bug into too many buckets. For example, if you compile your application one more time without any changes Module Build Date will changes however and same crash will be placed to another bucket, and weaknesses in the expanding heuristics, which result in mapping more than one bug into the same bucket. For example, if two different bugs crash inside strlen function because they call it with corrupted string there will be only one bucket for both; this occurs because the bucket is generated on the Windows OS client without performing any symbol analysis on the memory dump.
The module, picked by the Windows Error Reporting client is the module at the top of the stack. Investigations of many reports result in a faulting module, different from the original bucket determination. Software & hardware manufacturers may access their error reports using Microsoft's Windows Dev Center Hardware and Desktop Dashboard program. In order to ensure that error reporting data only goes to the engineers responsible for the product, Microsoft requires that interested vendors obtain a VeriSign Class 3 Digital ID or DigiCert certificate. Digital certificates provided by cheaper providers are not accepted. Software and hardware manufacturers can close the loop with their customers by linking error signatures to Windows Error Reporting Responses; this allows distributing solutions as well as collecting extra information from customers and providing them with support links. Microsoft has reported that data collected from Windows Error Reporting has made a huge difference in the way software is developed internally.
For instance, in 2002, Steve Ballmer noted that error reports enabled the Windows team to fix 29% of all Windows XP errors with Windows XP SP1. Over half of all Microsoft Office
The stock of a corporation is all of the shares into which ownership of the corporation is divided. In American English, the shares are known as "stocks." A single share of the stock represents fractional ownership of the corporation in proportion to the total number of shares. This entitles the stockholder to that fraction of the company's earnings, proceeds from liquidation of assets, or voting power dividing these up in proportion to the amount of money each stockholder has invested. Not all stock is equal, as certain classes of stock may be issued for example without voting rights, with enhanced voting rights, or with a certain priority to receive profits or liquidation proceeds before or after other classes of shareholders. Stock can be bought and sold or on stock exchanges, such transactions are heavily regulated by governments to prevent fraud, protect investors, benefit the larger economy; as new shares are issued by a company, the ownership and rights of existing shareholders are diluted in return for cash to sustain or grow the business.
Companies can buy back stock, which lets investors recoup the initial investment plus capital gains from subsequent rises in stock price. Stock options, issued by many companies as part of employee compensation, do not represent ownership, but represent the right to buy ownership at a future time at a specified price; this would represent a windfall to the employees if the option is exercised when the market price is higher than the promised price, since if they sold the stock they would keep the difference. A person who owns a specific percentage of the share has the ownership of the corporation proportional to his share; the shares together form stock. The stock of a corporation is partitioned into shares, the total of which are stated at the time of business formation. Additional shares may subsequently be authorized by the existing shareholders and issued by the company. In some jurisdictions, each share of stock has a certain declared par value, a nominal accounting value used to represent the equity on the balance sheet of the corporation.
In other jurisdictions, shares of stock may be issued without associated par value. Shares represent a fraction of ownership in a business. A business may declare different types of shares, each having distinctive ownership rules, privileges, or share values. Ownership of shares may be documented by issuance of a stock certificate. A stock certificate is a legal document that specifies the number of shares owned by the shareholder, other specifics of the shares, such as the par value, if any, or the class of the shares. In the United Kingdom, Republic of Ireland, South Africa, Australia, stock can refer to different financial instruments such as government bonds or, less to all kinds of marketable securities. Stock takes the form of shares of either common stock or preferred stock; as a unit of ownership, common stock carries voting rights that can be exercised in corporate decisions. Preferred stock differs from common stock in that it does not carry voting rights but is entitled to receive a certain level of dividend payments before any dividends can be issued to other shareholders.
Convertible preferred stock is preferred stock that includes an option for the holder to convert the preferred shares into a fixed number of common shares any time after a predetermined date. Shares of such stock are called "convertible preferred shares". New equity issue may have specific legal clauses attached that differentiate them from previous issues of the issuer; some shares of common stock may be issued without the typical voting rights, for instance, or some shares may have special rights unique to them and issued only to certain parties. New issues that have not been registered with a securities governing body may be restricted from resale for certain periods of time. Preferred stock may be hybrid by having the qualities of bonds of fixed returns and common stock voting rights, they have preference in the payment of dividends over common stock and have been given preference at the time of liquidation over common stock. They have other features of accumulation in dividend. In addition, preferred stock comes with a letter designation at the end of the security.
B, whereas Class "A" shares of ORION DHC, Inc will sell under ticker OODHA until the company drops the "A" creating ticker OODH for its "Common" shares only designation. This extra letter does not mean that any exclusive rights exist for the shareholders but it does let investors know that the shares are considered for such, these rights or privileges may change based on the decisions made by the underlying company. "Rule 144 Stock" is an American term given to shares of stock subject to SEC Rule 144: Selling Restricted and Control Securities. Under Rule 144, restricted and controlled securities are acquired in unregistered form. Investors either purchase or take ownership of these securities through private sales from the issuing company or from an affiliate of the issuer. Investors wishing to sell these securities are subject to different rules than those selling traditional common or preferred stock; these individuals will only be allowed to liquidate their securities after meeting the specific conditions set forth by SEC Rule 144.
Windows 8.1 is a personal computer operating system, produced by Microsoft and released as part of the Windows NT family of operating systems. It was released to manufacturing on August 27, 2013, reached general availability on October 17, 2013, about a year after the retail release of its predecessor. Windows 8.1 was made available as a free upgrade for retail copies of Windows 8 and Windows RT users via the Windows Store. Windows 8.1 aimed to address complaints of Windows 8 reviewers on launch. Visible enhancements include an improved Start screen, additional snap views, additional bundled apps, tighter OneDrive integration, Internet Explorer 11, a Bing-powered unified search system, restoration of a visible Start button on the taskbar, the ability to restore the previous behavior of opening the user's desktop on login instead of the Start screen. Windows 8.1 added support for such emerging technologies as high-resolution displays, 3D printing, Wi-Fi Direct, Miracast streaming, as well as the ReFS file system.
Windows 8.1 received better positive reception than Windows 8, with critics praising the expanded functionality available to apps in comparison to 8, its OneDrive integration, along with its user interface tweaks and the addition of expanded tutorials for operating the Windows 8 interface. Despite these improvements, Windows 8.1 was still criticized for not addressing all digressions of Windows 8, the potential privacy implications of the expanded use of online services. As of February 2019, 6.55% of Windows computers are running Windows 8.1. In February 2013, ZDNet writer Mary Jo Foley disclosed potential rumors about "Blue", the codename for a wave of planned updates across several Microsoft products and services, including Windows 8, Windows Phone 8, Outlook.com, SkyDrive. In particular, the report detailed that Microsoft was planning to shift to a more "continuous" development model, which would see major revisions to its main software platforms released on a consistent yearly cycle to keep up with market demands.
Lending credibility to the reports, Foley noted that a Microsoft staff member had listed experience with "Windows Blue" on his LinkedIn profile, listed it as a separate operating system from 8. A post-RTM build of Windows 8, build 9364, was leaked in March 2013; the build, believed to be of "Windows Blue", revealed a number of enhancements across Windows 8's interface, including additional size options for tiles, expanded color options on the Start screen, the expansion of PC Settings to include more options that were exclusive to the desktop Control Panel, the ability for apps to snap to half of the screen, the ability to take screenshots from the Share charm, additional stock apps, increased SkyDrive integration and Internet Explorer 11. Shortly afterward on March 26, 2013, corporate vice president of corporate communications Frank X. Shaw acknowledged the "Blue" project, stating that continuous development would be "the new normal" at Microsoft, that "our product groups are taking a unified planning approach so people get what they want—all of their devices and services working together wherever they are and for whatever they are doing."In early May, press reports announcing the upcoming version in Financial Times and The Economist negatively compared Windows 8 to New Coke.
The theme was echoed and debated in the computer press. Shaw rejected this criticism as "extreme", adding that he saw a comparison with Diet Coke as more appropriate. On May 14, 2013, Microsoft announced that "Blue" would be named Windows 8.1. Following a keynote presentation focusing on this version, the public beta of Windows 8.1 was released on June 26, 2013 during Build. Build 9600 of Windows 8.1 was released to OEM hardware partners on August 27, 2013, became available on October 17, 2013. Unlike past releases of Windows and its service packs, volume license customers and subscribers to MSDN Plus and TechNet Plus were unable to obtain the RTM version upon its release. However, after criticism, Microsoft reversed its decision and released the RTM build on MSDN and TechNet on September 9, 2013. Prior to the release of Windows 8.1, Microsoft premiered a new television commercial in late-September 2013 that focused on its changes as part of the "Windows Everywhere" campaign. Shortly after its release, Windows RT 8.1 was temporarily recalled by Microsoft following reports that some users had encountered a rare bug which corrupted the operating system's Boot Configuration Data during installation, resulting in an error on startup.
On October 21, 2013, Microsoft confirmed that the bug was limited to the original Surface tablet, only affected 1 in 1000 installations. The company released recovery media and instructions which could be used to repair the device, restored access to Windows RT 8.1 the next day. It was found that changes to screen resolution handling on Windows 8.1 resulted in mouse input lag in certain video games that do not use the DirectInput API's—particularly first-person shooter games, including Deus Ex: Human Revolution, Hitman: Absolution, Metro 2033. Users found the issues to be more pronounced when using gaming mice with high resolution and/or polling rates. Microsoft released a patch to fix the bug on certain games in November 2013, acknowledged that it was caused by "changes to mouse-input processing for low-latency interaction scenarios". On April 8, 2014, a day of the End of Support for Windows XP, Microsoft released the Windows 8.1 Update, w
A ticker symbol or stock symbol is an abbreviation used to uniquely identify publicly traded shares of a particular stock on a particular stock market. A stock symbol may consist of numbers or a combination of both. "Ticker symbol" refers to the symbols. Stock symbols are unique identifiers assigned to each security traded on a particular market. A stock symbol can consist of letters, numbers, or a combination of both, is a way to uniquely identify that stock; the symbols were kept as short as possible to reduce the number of characters that had to be printed on the ticker tape, to make it easy to recognize by traders and investors. The allocation of symbols and formatting convention is specific to each stock exchange. In the US, for example, stock tickers are between 1 and 4 letters and represent the company name where possible. For example, US-based computer company stock Apple Inc. traded on the NASDAQ exchange has the symbol AAPL, while the motor company Ford's stock, traded on the New York Stock Exchange has the single-letter ticker F.
In Europe, most exchanges use three-letter codes, for example Dutch consumer goods company Unilever traded on the Amsterdam Euronext exchange has the symbol UNA. While in Asia, numbers are used as stock tickers to avoid issues for international investors when using non-Latin scripts. For example, the bank HSBC's stock traded on the Hong Kong Stock Exchange has the ticker symbol 0005. Symbols sometimes change to reflect mergers. Prior to the 1999 merger with Mobil Oil, Exxon used a phonetic spelling of the company "XON" as its ticker symbol; the symbol of the firm after the merger was "XOM". Symbols are sometimes reused. In the US the single-letter symbols are sought after as vanity symbols. For example, since Mar 2008 Visa Inc. has used the symbol V, used by Vivendi which had delisted and given up the symbol. To qualify a stock, both the ticker and the exchange or country of listing needs to be known. On many systems both must be specified to uniquely identify the security; this is done by appending the location or exchange code to the ticker.
Although stock tickers identify a security, they are exchange dependent limited to stocks and can change. These limitations have led to the development of other codes in financial markets to identify securities for settlement purposes; the most prevalent of these is the International Securities Identifying Number. An ISIN uniquely identifies a security and its structure is defined in ISO 6166. Securities for which ISINs are issued include bonds, commercial paper and warrants; the ISIN code is a 12-character alpha-numerical code that does not contain information characterizing financial instruments, but serves for uniform identification of a security at trading and settlement. The ISIN identifies not the exchange on which it trades. For instance, Daimler AG stock trades on twenty-two different stock exchanges worldwide, is priced in five different currencies. ISIN cannot specify a particular trade in this case, another identifier the three- or four-letter exchange code will have to be specified in addition to the ISIN.
While a stock ticker identifies a security that can be traded, stock market indices are sometimes assigned a symbol though they can not be traded. Symbols for indices are distinguished by adding a symbol in front of the name, such as a caret or a dot. For example, Reuters lists the Nasdaq Composite index under the symbol. IXIC. In Canada the Toronto Stock Exchange TSX and the TSXV use the following special codes after the ticker symbol: In the United Kingdom, prior to 1996, stock codes were known as EPICs, named after the London Stock Exchange's Exchange Price Information Computer. Following the introduction of the Sequence trading platform in 1996, EPICs were renamed Tradable Instrument Display Mnemonics, but they are still referred to as EPICs. Stocks can be identified using their SEDOL number or their ISIN. In the United States, modern letter-only ticker symbols were developed by Standard & Poor's to bring a national standard to investing. A single company could have many different ticker symbols as they varied between the dozens of individual stock markets.
The term ticker refers to the noise made by the ticker tape machines once used by stock exchanges. The S&P system was standardized by the securities industry and modified as years passed. Stock symbols for preferred stock have not been standardized; some companies use a well-known product as their ticker symbol. Belgian brewer InBev, the brewer of Budweiser beer, uses "BUD" as its three-letter ticker for American Depository Receipts, symbolizing its premier product in the United States, its rival, Molson Coors Brewing Company, uses a beer-related symbol, "TAP". Southwest Airlines pays tribute to its headquarters at Love Field in Dallas through its "LUV" symbol. Cedar Fair Entertainment Company, which operates large amusement parks in the United States, uses "FUN" as its symbol. Harley-Davidson uses "HOG" for its Harley Owners Group. Yamana Gold uses "AUY", because on the periodic table of elements. Sotheby's uses the symbol "BID". While most symbols come from the company's name, sometimes it happens the other way around.

In the aviation industry, a flight number or flight designator is a code for an airline service consisting of two-character airline designator and a 1 to 4 digit number. For example, "KL 445" is a KLM service from Amsterdam to Kuwait. A service is called "direct" if it is covered by a single flight number, regardless of the number of stops or equipment changes. For example, "WN 417" flies from Jacksonville to Baltimore to Oakland to Los Angeles. A given flight segment may have multiple flight numbers on different airlines under a code-sharing agreement. Speaking, the flight number is just the numerical part, but it is used for the entire flight designator; the flight designator of the operating carrier of a commercial flight is used as a callsign. This is distinct from the aircraft's registration number. A number of conventions have been developed for defining flight numbers, although these vary from airline to airline, are being modified. Eastbound and northbound flights are traditionally assigned numbers, while westbound and southbound flights have odd numbers.
Other airlines will use an odd number for an outbound flight and use the next number for the reverse inbound flight. For destinations served by multiple flights per day, numbers tend to increase during the day. Hence, a flight from point A to point B might be flight 101 and the return flight from B to A would be 102, while the next pair of flights on the same route would be assigned codes 103 and 104. Flight numbers of less than three digits are assigned to long-haul or otherwise premium flights. Flight number 1 is used for an airline's "flagship" service. For example, British Airways flight 1 was the early morning supersonic Concorde service from London to New York City and is now a premium business-class only flight between the same cities. American Airlines Flight 1 is the daily flight from New York to Los Angeles. Four-digit numbers in the range 3000 to 5999 represent regional affiliate flights, while numbers larger than 6000 are codeshare numbers for flights operated by different airlines or railways.
Flight numbers larger than 9000 refer to ferry flights. Flight numbers starting with 8 are used for charter flights, but it always depends on the commercial carrier's choice. In a codeshare, airlines shares its aircraft with another airline, resulting in the flight having more than one flight number on the same sector, either the same or different flight numbers on joined sectors; as a hypothetical example, flight QQ1234 may fly from airport AAA to BBB to CCC. The AAA-BBB segment may be serviced by airline QQ, the BBB-CCC segment by airline RR, on a different aircraft; the same flight may be sold as RR3210, by a third airline SS as SS2345. The individual flight legs may have multiple flight numbers: AAA-BBB may be QQ12, RR23, SS45. For example, Alaska Airlines flight AS61 as of June 2018 flies from Juneau to Yakutat to Cordova to Anchorage. A ticket for the Yakutat to Anchorage segment is specified as AS61 YAK-ANC, it is possible for a given flight number to cover a sequence beginning and ending at the same airport.
Most flights are non-stop from A to B, few are from A to B to C. Aircraft type may change due to operation need. Note*: BA1 stops at Shannon, Ireland only for refuelling and for passengers go through U. S. Immigration and Customs' preclearance. Flight numbers are taken out of use after a crash or a serious incident. For example, following the crash of Alaska Airlines Flight 261, the airline changed the flight number for subsequent flights following the same route to 229. American Airlines Flight 77, which flew from Dulles International Airport in Washington, DC, to Los Angeles International Airport, was changed to Flight 149 after the September 11 attacks. On the other hand, other considerations may lead an airline not to change a flight number. There are at least four instances of flight numbers that have suffered two serious accidents: Flight 253 of Linea Aeropostal Venezolana, Flight 869 of United Arab Airlines, Flight 800 of TWA, Flight 383 of American Airlines. Another example of this is the retirement of both MH370 and MH371 after an aircraft disappeared in 2014.
Airline mega mergers, in markets such as the United States, have made it necessary to break conventional flight numbering schemes. Organizations such as IATA, ICAO, ARC, as well as CRS systems and the FAA's ATC systems limit flight numbers to four digits; the pool of available flight numbers has been outstripped by demand for them by emergent mega-carriers. As such, some carriers use the same flight number for back-and-forth flights, or in other cases carriers have assigned a single flight number to an multi-leg f
A Post-it Note is a small piece of paper with a re-adherable strip of glue on its back, made for temporarily attaching notes to documents and other surfaces. A low-tack pressure-sensitive adhesive allows the notes to be attached, removed and re-posted elsewhere without leaving residue. Small yellow squares, Post-it Notes and related products are available in various colors, shapes and adhesive strengths. Although 3M's patent expired in 1997, "Post-it" and the original notes' distinctive yellow color remain registered company trademarks, with terms such as "repositionable notes" used for similar offerings manufactured by competitors. While use of the trademark'Post-it' in a representative sense refers to any sticky note, no legal authority has held the trademark to be generic. In 1968, Dr. Spencer Silver, a scientist at 3M in the United States, was attempting to develop a super-strong adhesive. Instead, he accidentally created a "low-tack", pressure-sensitive adhesive. For five years, Silver promoted his "solution without a problem" within 3M both informally and through seminars, but failed to gain acceptance.
In 1974, a colleague who had attended one of his seminars, Art Fry, came up with the idea of using the adhesive to anchor his bookmark in his hymn book. Fry utilized 3M's sanctioned "permitted bootlegging" policy to develop the idea; the original notes' yellow color was chosen by accident, as the lab next-door to the Post-It team had only yellow scrap paper to use.3M launched the product as "Press'n Peel" bookmark in stores in four cities in 1977, but results were disappointing. A year 3M instead issued free samples directly to consumers in Boise, with 94 percent of those who tried them indicating they would buy the product; the product was sold as "Post-Its" in 1979 when the rollout introduction began, was sold across the United States from April 6, 1980. The following year, they were launched in Europe. In 2003, the company came out with "Post-it Brand Super Sticky Notes", with a stronger glue that adheres better to vertical and non-smooth surfaces; until 3M's patent expired in the 1990s, Post-it type notes were produced only in the company's plant in Cynthiana, Kentucky.
In 2018, 3M launched the new "Post-It Extreme Notes", designed to be more durable and water-resistant, to stick to a variety of surfaces to which regular Post-It notes do not adhere. The Post-It Extreme Notes were designed with work environments like construction and manufacturing in mind. Inventor Alan Amron has made claims to be the inventor who in 1973 disclosed the technology used on the Post-it Note to 3M in 1974, his 1997 suit against 3M was settled and 3M paid Amron. As part of the settlement, Amron undertook not to make future claims against the company except if a breach of the settlement agreement should occur. However, in 2016, he launched a further suit against 3M, asserting that 3M were wrongly claiming to be the inventors, seeking $400 million in damages. At a preliminary hearing, a federal judge ordered the parties to undergo mediation; the suit was subsequently dismissed declaring the previous 1998 settlement agreement to be upheld. In July 2016 a former 3M marketing department employee, Daniel Dassow, voluntarily came forward as an eyewitness that in 1974 Alan Amron had in fact disclosed his Press-on memo sticky notes invention to 3M.
"The Yellow Stickee Diary of a Mad Secretary," by Rosa Maria Arenas, is the mini graphic journal of an office worker/artist, exhibited July 7 - August 25, 2013, at the Michigan Institute of Contemporary Art Gallery in Lansing, Michigan. The 41 drawings displayed are a tiny percentage of the more than 2000 original drawings that constitute the Yellow Stickee Diary Project which Arenas created while working temp jobs from 1994 to 2005. Printed with archival inks on archival paper, the reproductions include "stickee sized" framed prints and enlargements of the original drawings. In 2012, Turkish artist Ardan Özmenoğlu was selected to have a solo exhibition at Bertrand Delacroix Gallery in the art district of Chelsea, Manhattan; the exhibition, titled "E Pluribus Unum", opened November 15, 2012 and featured large scale works on Post-It Notes. In 2004, Paola Antonelli, a curator of architecture and design, included Post-it Notes in a show entitled "Humble Masterpieces". Rebecca Murtaugh, a California artist who uses Post-it Notes in her artwork, in 2001 created an installation by covering her whole bedroom with $1000 worth of the notes, using the ordinary yellow for objects she saw as having less value and neon colors for more important objects, such as the bed.
In 2000, the 20th anniversary of Post-it Notes was celebrated by having artists create artworks on the notes. One such work, by the artist R. B. Kitaj, sold for £ 640 in an auction; the Lennon Wall, a message board created during the 2014 Hong Kong protests from a stretch of curved staircase in the Central Government Complex, is covered in multi-coloured Post-It Notes with handwritten messages from supporters. Satiregram, a parody account on Instagram by Euzcil Castaneto, showcases handwritten messages on Post-it Notes that describe typical pictures people would post on Instagram. Virtual Post-It Notes have been created for computer in the form of desktop notes; these include 3M's own Post-it Brand Software Notes, Stickies in Mac OS, Sticky Notes in Windows, or other applications like ShixxNOTE. Virtual Post-It–like notes are available online using Evernote, Google Keep, or Microsoft OneNote. In 1997, 3M sued Microsoft for trademark infringement for using the term "Post-It" in a help file.
