Abstract: A system for recycling drilling fluid. The system has a washer coupled to a drilling rig. The washer receives drill cuttings with entrained drilling fluid. The drilling fluid has a base, and the washing fluid has the same base fluid. The washer fluid is used to remove drilling fluid from the drill cuttings. The washed drill cuttings are sent to a shaker to separate the solids. The spent washing fluid is sent to a filter which separates solids and recovers the base fluid. The base fluid can then be used for drilling or washing.

Abstract: A method, system and computer program product for obtaining vector representations of code snippets capturing semantic similarity. A first and second training set of code snippets are collected, where the first training set of code snippets implements the same function representing semantic similarity and the second training set of code snippets implements a different function representing semantic dissimilarity. A vector representation of a first and second code snippet from either the first or second training set of code snippets is generated using a machine learning model. A loss value is generated utilizing a loss function that is proportional or inverse to the distance between the first and second vectors in response to receiving the first and second code snippets from the first or second training set of code snippets, respectively. The machine learning model is trained to capture the semantic similarity in the code snippets by minimizing the loss value.

Abstract: A social networking system receives information describing locations associated with a plurality of its users. Based on information identifying each user and a location associated with each user, the social networking system generates and stores hash values. For example, the social networking system maintains various geo-tiles that each identify geographic areas and generates a hash value based on a user identifier and an identifier of a geo-tile including the location associated with the user. Based on the hash values and locations associated with one or more users, the online system determines a number of unique users associated with locations included in a geographic region. When determining the number of unique users, the online system accounts for a rate at which the online system updates location information associated with various users.

Abstract: Embodiments relate to using flux or underfill as a trapping layer for temporarily attaching light emitting diodes (LEDs) to a substrate and heating to simultaneously bond multiple LEDs onto the substrate. The flux or underfill may be selectively coated at the ends of electrodes of the LEDs prior to placing the LEDs on the substrate. Due to adhesive properties of the flux or underfill, multiple LEDs can be placed on and attached to the substrate prior to performing the bonding process. Once LEDs are placed on the substrate, the flux or underfill facilitates formation of metallic contacts between electrodes of the LED and contacts of the substrate during the bonding process. By using the flux or underfill, the formation of metallic contacts can be performed even without applying pressure.

Abstract: Techniques related to optics formation using pick-up tools are disclosed. Optical elements are formed by pressing a pick-up tool (PUT) against elastomeric material deposited on a light-outputting side of light-emitting diode (LED) devices. Pressing the PUT against the elastomeric material causes a molded shape of the PUT to be transferred to the elastomeric material. This forms the optical elements in the elastomeric material.

Abstract: A light emitting diode (LED) includes an elastomeric material that facilitates adhesive attachment with a pick-up head for pick and place operations. The LED includes an epitaxial layer defining a mesa structure and a light emitting surface. The mesa structure includes an active layer to emit light, and the emitted light is reflected at the mesa structure toward a light emitting region of the light emitting surface and transmitted at the light emitting region. An elastomeric material is on a portion of the light emitting surface, such as the light emitting region or a passive region. At the light emitting region, the elastomeric material may be shaped as a lens that collimates light transmitted from the light emitting region, and also facilitates adhesion to the pick-up head. At the passive region, the elastomeric material facilitates adhesion to the pick-up head without interfering with light emitted from the light emitting region.
