Residual vectors are compressed in a lossless compression scheme suitable for cloud DVR video content applications. Thus, a cloud DVR service provider can take many copies of the same file stored in the cloud and save storage space by compressing those copies while still maintaining their status as distinct copies, one per user. Vector quantization is used for compressing already-compressed video streams (e.g., MPEG streams). As vector quantization is a lossy compression scheme, the residual vector has to be stored to regenerate the original video stream at the decoding (playback) node. Entropy coding schemes like Arithmetic or Huffman coding can be used to compress the residual vectors. Additional strategies can be implemented to further optimize this residual compression. In some embodiments, the techniques operate to provide a 25-50% improvement in compression. Storage space is thus more efficiently used and video transmission may be faster in some cases.

Some embodiments execute a guest-introspection (GI) agent on each machine from which contextual attributes need to be captured. In addition to executing one or more machines on each host computer, these embodiments also execute a context engine and one or more attribute-based service engines on each host computer. One of these service engines is a firewall engine. Through the GI agents of the machines on a host, the context engine of that host in some embodiments collects contextual attributes associated with network events and/or process events on the machines. The context engine then provides the contextual attributes to the firewall engine, which, in turn, use these contextual attributes to identify firewall rules to enforce.

Techniques are described for relaying of high-band radiofrequency communications through a window that would otherwise partially or completely block the communications. For example, embodiments include a pair of high-band-to-optical (HB2O) relays mounted on either side of a window. One of the relays receives a high-band radiofrequency (HB-RF) communication signal that is unable to pass through the window and converts the HB-RF communication signal to an optical communication signal. As the window is substantially transparent to visible-spectrum light, the optical communication signal can pass through the window. The optical communication signal is transmitted through the window to the other HB2O relay, and the other HB2O relay converts back to a HB-RF communication signal. Thus, HB-RF networks on either side of the window can be communicatively coupled via the optical communications provided by the pair of relays.

A technique for determining the centroid for fragments generated using variable rate shading. Because the barycentric interpolation used to determine texture coordinates for pixels is based on the premise that the point being interpolated is within the triangle, centroids that are outside of the triangle can produce undesirable visual artifacts. Another concern, however, is that the further the centroid is from the center of a pixel, the less accurate quad-based pixel derivatives become for attributes of that pixel. To address these concerns, the position of the sample that is both covered by the triangle and the closest to the center of the pixel, out of all covered samples of the pixel, is used as the centroid for a partially covered pixel. For a fully covered pixel (all samples in a pixel are covered by a triangle), the center of that pixel is used as the centroid.

In order to avoid near-point stress on the eyes which may lead to the onset of myopia and/or accelerate the progression of myopia, especially in children or young adults, the system of the present invention monitors viewing distance and automatically distorts the image and/or text display into a format that is unreadable, for example, through blurring or pixilation, when the device is too close to the viewer. Alternatively, the system may automatically turn off the display when the device is too close and turn the display on when the device is at the proper viewing distance.

Topics are determined for short text messages using an unsupervised topic model. In a training corpus created from a number of short text messages, a vocabulary of words is identified, and for each word a distributed vector representation is obtained by processing windows of the corpus having a fixed length. The corpus is modeled as a Gaussian mixture model in which Gaussian components represent topics. To determine a topic of a sample short text message, a posterior distribution over the corpus topics is obtained using the Gaussian mixture model.

Acquisition of a font portion using a compression mechanism is described. In certain embodiments, an end-user device determines multiple characters to be displayed but are missing from a local font. The end-user device computes a compressed representation of the multiple characters based on multiple code points corresponding to the multiple characters. The end-user device transmits a font request including the compressed representation to a font repository. The font request may be implemented as a uniform resource locator (URL). The font repository, such as a server, decodes the compressed representation to identify at least the multiple code points encoded by the end-user device. The font repository prepares a font description including glyph data corresponding to the multiple code points and returns the font description. The end-user device produces a local font that includes at least multiple glyphs corresponding to the multiple requested characters. The local font production may include font augmentation.

Various embodiments described herein provide for track assignment of wires of a network of a circuit design by dynamic programming. In particular, various embodiments use a dynamic programming process to determine a set of breaking points for a routing wire of a global-routed and layer-assigned circuit design, and to determine track assignments for each of the sub-wires (sub-routes) formed by applying the set of selected breaking points to the routing wire. This results in a set of track-assigned sub-wires (or track-assigned sub-routes), which various embodiments can connect together to generate a connected set of track-assigned sub-wires that can be used in place of the routing wire.
