An Official Tweetstorm Feature Will Ruin Twitter Again. Twitter is reportedly testing a feature on its Android app that would automatically reformat large blocks of text into long self reply threads, or tweetstorms. This would ruin Twitter, which has already been ruined multiple times by new features. Past Twitter ruining features include GIPHY integration, which encourages mediocre GIF responses that turn a viral tweets replies into a wall of samey celebrity animations. A heightened reply limit lets users drag a dozen strangers into an unwanted public thread group DMs let spammers drag a dozen strangers into an unwanted private thread.

The algorithmic timeline makes conversation around live events Twitters killer app incoherent hashtags try to fix that, but instead they make normies write like robots in hopes of gaining a hundredth follower. Twitter just added a new feature that lets you add a seemingly infinite number of people to aRead more Read. The moments tab is condescending the reporting feature is half assed and easily abused, as is banning notifications include useless information like someone liked a reply to you. Likes were better as faves. Live updating reaction counts are distracting lists are awkward self replies mean tweets move around in your timeline as youre trying to read them multi user threading is impossible to parse now so everyone thinks theyre being insulted by their own team.

Matt Navarra, director of social media at The Next Web, credits screencaps of this new potentially Twitter ruining feature to someone named Devesh Logendran, whom hes also credited for shots of several alleged upcoming Facebook features. Twitter declined to comment about the supposed feature. But such a feature would not be out of character for a service constantly reinventing how to ruin itself. While Im not against tweetstorming, and have in fact encouraged it, there are certain strategies to it, and certain difficulties. How someone approaches these difficulties provides crucial context for the value of the tweetstorm.

S. president, for example, rarely manages to thread his own tweetstorms. In 2. 01. 6, after killing blogs dead, Twitter considered massively expanding its character limitor,Read more Read. Context clues abound. Does the user know how many tweets theyll send Does the hundredth tweet deliver on the promises of the first, or does the thread spill out, like over noticed political consultant Eric Garlands, into a rambling mess Does the writer compose each tweet as a standalone unit, fit for retweeting, or do they break off in the middle of sentences, proving that they should have put their rant on Medium instead, but chose Twitter because theyre desperate to have every sentence likedUnder the model depicted in TNWs screenshots, these signifiers would disappear. Twitter, says TNW, would automatically split a block of text into multiple tweets, then attach a clean parenthetical count to each. The storm would approach and dump its contents, just a long essay poorly broken up into tweets, calling attention to just how weird and dumb a tweetstorm can appear, while simultaneously wiping away the organic markers of the writers unhinged approach. Of course, users will always have the choice to tweetstorm the old fashioned way. The real danger is what new horrors the users will achieve with the feature. Most of the existing features only ruined Twitter because of their unintended consequences. What can spammers, hoaxers, and Nazis achieve with this new toolProbably more than the well behaved users, who just want a nice place to put one sentence at a time. Read Write Excel file in Java with Apache POIApache POI is a powerful Java library to work with different Microsoft Office file formats such as Excel, Power point, Visio, MS Word etc. The name POI was originally an acronym for Poor Obfuscation Implementation, referring humorously to the fact that the file formats seemed to be deliberately obfuscated, but poorly, since they were successfully reverse engineered. In this tutorial we will use Apache POI library to perform different functions on Microsoft Excel spreadsheet. Spring Batch Read Multiple Xml Files' title='Spring Batch Read Multiple Xml Files' />Lets get started. Tools Technologies Java JDK 1. Apache POI library v. Eclipse 3. 2 above optional1. Add Apache POI dependency. Make sure to include apache poi jar file to your project. If your project uses Maven as dependency management, add following in your Pom. Id org. apache. Id. Id poilt artifact. Id. lt version 3. If you are not using Maven then you can directly add required JAR files in your classpath. Download poi 2. 5. Include this file in your projects class path. Create new java project in eclipse with auto generated main function. Read Excel File. To read an excel file, Apache POI provides certain easy to use APIs. In below sample code we use different classes from POI library to read content of cell from excel file. This is for quick reference. HSSFSheet. import org. HSSFWorkbook. File. Input. Stream file new File. Input. Streamnew FileC test. Get the workbook instance for XLS file. HSSFWorkbook workbook new HSSFWorkbookfile. Get first sheet from the workbook. HSSFSheet sheet workbook. Sheet. At0. Get iterator to all the rows in current sheet. Iteratorlt Row row. Iterator sheet. Get iterator to all cells of current row. Iteratorlt Cell cell. Iterator row. cell. Iterator. Notice how each class in POI library starts with HSSF prefixHSSFWorkbook, HSSFSheet etc. HSSF stands for Horrible Spread. Sheet Format Im not kidding. It really is. Similar to HSSF, POI has different prefix for other file formats too HSSF Horrible Spread. Sheet Format reads and writes Microsoft Excel XLS format files. XSSF XML Spread. Sheet Format reads and writes Office Open XML XLSX format files. HPSF Horrible Property Set Format reads Document Summary information from Microsoft Office files. HWPF Horrible Word Processor Format aims to read and write Microsoft Word 9. DOC format files. HSLF Horrible Slide Layout Format a pure Java implementation for Microsoft Power. Point files. HDGF Horrible Dia. Gram Format an initial pure Java implementation for Microsoft Visio binary files. HPBF Horrible Pu. Blisher Format a pure Java implementation for Microsoft Publisher files. HSMF Horrible Stupid Mail Format a pure Java implementation for Microsoft Outlook MSG files. DDF Dreadful Drawing Format a package for decoding the Microsoft Office Drawing format. Working with. xlsx files. The classes we used in above code snippet, HSSFWorkbook and HSSFSheet works for. In order to work with newer xls format viz. POI classes like import org. HSSFSheet. import org. XSSFSheet. File. Input. Stream file new File. Input. Streamnew FileC test. Get the workbook instance for XLS file. XSSFWorkbook workbook new XSSFWorkbook file. Get first sheet from the workbook. XSSFSheet sheet workbook. Sheet. At0. Get iterator to all the rows in current sheet. Iteratorlt Row row. Iterator sheet. Get iterator to all cells of current row. Iteratorlt Cell cell. Iterator row. cell. Iterator. Use XSSFWorkbook and XSSFSheet class in all of the below examples in order to make them work with. Consider a sample excel file test. We will read above xls file using Apache POI and prints the data. File. Input. Stream file new File. Input. Streamnew FileC test. Get the workbook instance for XLS file. HSSFWorkbook workbook new HSSFWorkbookfile. Get first sheet from the workbook. HSSFSheet sheet workbook. Sheet. At0. Iterate through each rows from first sheet. Iteratorlt Row row. Iterator sheet. Iterator. Next. Row row row. Iterator. For each row, iterate through each columns. Iteratorlt Cell cell. Iterator row. cell. Iterator. whilecell. Iterator. has. Next. Cell cell cell. Iterator. Cell. Type. case Cell. CELLTYPEBOOLEAN. System. Boolean. Cell. Value tt. Cell. CELLTYPENUMERIC. System. out. printcell. Great Circle Calculation. Numeric. Cell. Value tt. Cell. CELLTYPESTRING. System. out. printcell. String. Cell. Value tt. System. out. println. File. Output. Stream out. File. Output. Streamnew FileC test. File. Not. Found. Exception e. e. Stack. Trace. catch IOException e. Stack. Trace. The above code is self explanatory. It read the sheet from workbook and iterate through each row and cell to print its values. Just note how we use different methods like get. Boolean. Cell. Value, get. Numeric. Cell. Value etc to read cell value. Before reading a cell content, we need to first determine its type using method cell. Cell. Type and then call appropriate method to read content. Output Emp IdNameSalary. John2. 00. 00. 00. Dean4. 20. 00. 0. Sam2. 80. 00. 0. Cass6. 00. 00. 00. Create New Excel File. Let us create a new excel file and write data in it. Following is the API which we will use for this purpose. HSSFSheet. import org. HSSFWorkbook. HSSFWorkbook workbook new HSSFWorkbook. HSSFSheet sheet workbook. SheetSample sheet. Create a new row in current sheet. Row row sheet. create. Row0. Create a new cell in current row. Cell cell row. create. Cell0. Set value to new value. Cell. ValueBlahblah. Below is the complete code that writes a new excel with dummy data HSSFWorkbook workbook new HSSFWorkbook. HSSFSheet sheet workbook. SheetSample sheet. Maplt String, Object data new Hash. Maplt String, Object. Object Emp No., Name, Salary. Object 1d, John, 1. Object 2d, Sam, 8. Object 3d, Dean, 7. Setlt String keyset data. Set. int rownum 0. String key keyset. Row row sheet. create.

Trace. catch IOException e. Stack. Trace. Output new. Update Existing Excel File. Updating an existing excel file is straight forward. Open the excel using different API that we discussed above and set the cells value. One thing we need to note here is that we can update the excel file only when we close it first. Following Java code read the above excel file and doubles the salary of each employee try. File. Input. Stream file new File. Input. Streamnew FileC update. HSSFWorkbook workbook new HSSFWorkbookfile. HSSFSheet sheet workbook. Sheet. At0. Cell cell null. Update the value of cell. Row1. get. Cell2. Cell. Valuecell. Numeric. Cell. Value 2. Row2. Cell2.
