GitHub’s website currently seems to be: Using blob for files, and tree for directories, in URLs; Redirecting browsers which request file URLs containing tree to contain blob instead; and Redirecting browsers which request directory URLs containing blob to URLs containing tree instead. It’s possible that GitHub’s website, at the time you asked the question, was … Read more
You can use the MySQL function OCTET_LENGTH(your_column_name). See here for more details.
To insert a VARCHAR2 into a BLOB column you can rely on the function utl_raw.cast_to_raw as next: insert into mytable(id, myblob) values (1, utl_raw.cast_to_raw(‘some magic here’)); It will cast your input VARCHAR2 into RAW datatype without modifying its content, then it will insert the result into your BLOB column. More details about the function utl_raw.cast_to_raw
Your best option is to use a blob url (which is a special url that points to an object in the browser’s memory) : var myBlob = …; var blobUrl = URL.createObjectURL(myBlob); Now you have the choice to simply redirect to this url (window.location.replace(blobUrl)), or to create a link to it. The second solution allows … Read more
I found the solution before to post. The change of charset has not been resolved, in fact. However, I sent the UTF-8 header for the download process and Excel was able to understand the file format correctly. Thanks to this response of Erik Töyrä. blob = new Blob([“\ufeff”, csv_content]);

So if your original URI contains that filename, the easiest might be to simply make your <object>’s data to the URI you fetched the pdf from directly, instead of going the Blob’s way. Now, there are cases … Read more
Blobs are “immutable” so you can’t change one after making it. Constructing a new Blob that appends the data to an existing blob (as you wrote in your initial question) is a good solution. If you don’t need to use the Blob each time you append a part, you can just track an array of … Read more
You can do this in two ways: Load the image source using XMLHttpRequest() or fetch() instead of an image element Convert image element via a canvas element. This will recompress the image causing some quality loss. There is also the “risk” of color/gamma changes depending of the image contains ICC/gamma information and/or the browser support … Read more
I’ve found. It was so simple that I didnt even see it… /** * @param {Blob} videoFile * @param {HTMLVideoElement} videoEl * @returns {void} */ function display( videoFile, videoEl ) { // Preconditions: if( !( videoFile instanceof Blob ) ) throw new Error( ‘`videoFile` must be a Blob or File object.’ ); // The `File` … Read more
