In 1968 Shirley Chisholm became the first Black woman elected to the United States Congress. In 1972 she launched a campaign for the Democratic presidential nomination, breaking another political barrier.

The MSU Lossless Video Codec is a video codec developed by the Graphics & Media Lab Video Group of Moscow State University. It was designed to provide space-effective lossless video compression. As of 2007 MSU had the second-best compression ratio when compared to many other lossless video codecs, with the better result shown by YULS codec.
Huffyuv (or HuffYUV) is a lossless video codec created by Ben Rudiak-Gould which is meant to replace uncompressed YCbCr as a video capture format. The codec can also compress in the RGB color space. "Lossless" means that the output from the decompressor is bit-for-bit identical with the original input to the compressor. Lossless only occurs when the compression color space matches the input and output color space. When the color spaces do not match, a low loss compression is performed. Huffyuv's algorithm is similar to that of lossless JPEG, in that it predicts each sample and then Huffman-encodes the error. The predictor is intraframe-only.
FFV1 (short for FF Video 1) is a lossless intra-frame video coding format. FFV1 is particularly popular for its performance regarding speed and size, compared to other lossless preservation codecs, such as Motion JPEG 2000. The encoder and decoder have been part of the free, open-source library libavcodec in the FFmpeg project since June 2003. FFV1 is also included in ffdshow and LAV Filters, which makes the video codec available to Microsoft Windows applications that support system-wide codecs over Video for Windows (VfW) or DirectShow. FFV1 has been standardized at the IETF under RFC 9043. The European Broadcasting Union (EBU) lists FFV1 under the codec-family index "31" in their combined list of video codec references.
YULS or YUVsoft's Lossless Video Codec, a lossless video codec developed by YUVsoft, was designed to produce highly compressed lossless video. YULS compares favorably, in terms of compression ratio, with other codecs.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
