Our new Science of Reading: Beyond Phonics series ends with our
\r\n'Foster Joy in Early Readers' webinar.
\r\nThis is perfect for new and returning users who teach grades K-8! Learn how to set your early readers up for success by using the Article-A-Day routine, along with our knowledge-building decodables. All registrants will receive a webinar recording, and attendees will get a

We've interviewed several authors on our School Me podcast. Donna Barba Higuera discusses El Cucuy is Scared, Too! and why she is so passionate about writing books that feature multiracial children, families, and identities. Wendy Shang, author of The Secret Battle of Evan Pao talks about why representation matters. Andrea Davis Pinkney, author of Loretta Little Looks Back: Three Voices Go Tell It, discusses the power of storytelling. And Duncan Tonatiuh, author of A Land of Books: Dreams of Young Mexihcah Word Painters, makes the case for the freedom to read.
Certain browsers may sanitize the clipboard data when it is read, to prevent malicious content from being pasted into the document. For example, Chrome (and other Chromium-based browsers) sanitizes HTML data by stripping tags and other potentially dangerous content. Use the unsanitized array to specify a list of MIME types that should not be sanitized.
The remaining code reads the clipboard when the destination element is clicked and copies the image data into the destinationImage element. It logs an error if it is unable to use the read() method, or if the clipboard does not contain data in PNG format.
Copy the butterfly image on the left by right-clicking the image and selecting "Copy image" from the context menu. Then click on the empty frame on the right. The example will fetch the image data from the clipboard and display the image in the empty frame.
The remaining code reads the clipboard when the destination element is clicked and displays each ClipboardItem element along with its MIME type. It logs an error it is unable to use the read() method, or if the clipboard contains any other MIME type.
Copy some text or the butterfly (JPG) image below (to copy images right-click on them and then select "Copy image" from the context menu). Select the indicated frame below to paste this information from the clipboard into the frame.
First click the "Copy HTML" button to write the HTML code from the first textarea to the clipboard. Then either click the "Paste HTML" button or the "Paste unsanitized HTML" button to paste the sanitized or unsanitized HTML code into the second textarea.

Most people spend it getting dressed, getting ready, and rushing out the door. What if that time was spent making yourself a better person? What if you woke up an hour before you needed to each day and worked on yourself? How much better would you be at work, in your relationships, and as a person?

James Clear writes about habits, decision making, and continuous improvement. He is the author of the #1 New York Times bestseller, Atomic Habits. The book has sold over 20 million copies worldwide and has been translated into more than 60 languages.
On files that support seeking (for example, a regular file), the read() shall start at a position in the file given bythe file offset associated with fildes. The file offset shall be incremented by the number of bytes actually read.
No data transfer shall occur past the current end-of-file. If the starting position is at or after the end-of-file, 0 shall bereturned. If the file refers to a device special file, the result of subsequent read() requests isimplementation-defined.
If some process has the pipe open for writing and O_NONBLOCK is clear, read() shall block the calling thread until somedata is written or the pipe is closed by all processes that had the pipe open for writing.
The read() function reads data previously written to a file. If any portion of a regular file prior to the end-of-filehas not been written, read() shall return bytes with value 0. For example, lseek() allows the file offset to be set beyond the end of existing data in the file. If datais later written at this point, subsequent reads in the gap between the previous end of data and the newly written data shallreturn bytes with value 0 until data is written into the gap.
[SIO] If the O_DSYNC and O_RSYNC bits have been set, read I/O operations on the file descriptor shall complete as defined by synchronizedI/O data integrity completion. If the O_SYNC and O_RSYNC bits have been set, read I/O operations on the file descriptor shallcomplete as defined by synchronized I/O file integrity completion.
By default, STREAMs are in control-normal mode, in which a read() from a STREAMS file can only process messages thatcontain a data part but do not contain a control part. The read() shall fail if a message containing a control part isencountered at the STREAM head. This default action can be changed by placing the STREAM in either control-data mode orcontrol-discard mode with the I_SRDOPT ioctl() command. In control-data mode,read() shall convert any control part to data and pass it to the application before passing any data part originally presentin the same message. In control-discard mode, read() shall discard message control parts but return to the process any datapart in the message.
Upon successful completion, these functions shall return a non-negative integer indicating the number of bytes actually read.Otherwise, the functions shall return -1 and set errno to indicate the error.
This volume of POSIX.1-2017 does not specify the value of the file offset after an error is returned; there are too many cases.For programming errors, such as [EBADF], the concept is meaningless since no file is involved. For errors that are detectedimmediately, such as [EAGAIN], clearly the offset should not change. After an interrupt or hardware error, however, an updatedvalue would be very useful and is the behavior of many implementations.
The use of I/O with large byte counts has always presented problems. Ideas such as lread() and lwrite() (using andreturning longs) were considered at one time. The current solution is to use abstract types on the ISO C standardfunction to read() and write(). The abstract types can be declared so thatexisting functions work, but can also be declared so that larger types can be represented in future implementations. It is presumedthat whatever constraints limit the maximum range of size_t also limit portable I/O requests to the same range. This volumeof POSIX.1-2017 also limits the range further by requiring that the byte count be limited so that a signed return value remainsmeaningful. Since the return type is also a (signed) abstract type, the byte count can be defined by the implementation to belarger than an int can hold.
The standard developers considered adding atomicity requirements to a pipe or FIFO, but recognized that due to the nature ofpipes and FIFOs there could be no guarantee of atomicity of reads of PIPE_BUF or any other size that would be an aid toapplications portability.
This volume of POSIX.1-2017 requires that no action be taken for read() or write() when nbyte is zero. This is not intended to take precedence over detection oferrors (such as invalid buffer pointers or file descriptors). This is consistent with the rest of this volume of POSIX.1-2017, butthe phrasing here could be misread to require detection of the zero case before any other errors. A value of zero is to beconsidered a correct value, for which the semantics are a no-op.
I/O is intended to be atomic to ordinary files and pipes and FIFOs. Atomic means that all the bytes from a single operation thatstarted out together end up together, without interleaving from other I/O operations. It is a known attribute of terminals thatthis is not honored, and terminals are explicitly (and implicitly permanently) excepted, making the behavior unspecified. Thebehavior for other device types is also left unspecified, but the wording is intended to imply that future standards might chooseto specify atomicity (or not).
