Abstract: The disclosed computer-implemented method may include systems for generating personalized avatar reactions during live video broadcasts. For example, the systems and methods described herein can access a social networking system user's profile to identify an avatar associated with the social networking system user. The systems and methods can generate an avatar reaction by modifying one or more features of the avatar based on a corresponding emoticon reaction. Once generated, the social networking system user can select the avatar reaction for addition to an ephemeral reaction stream associated with a live video broadcast. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: Shoe with detachable sole and vamp, in which: the sole (1) has an upper surface (2) on which several tubular elements (4) are applied spaced from each other by a preset value; the vamp (7) has a lower surface (6) on which there are applied several tubular elements (8) spaced from each other by a preset value; the vamp (7) can be positioned onto the sole (1) by positioning said lower surface (6) of the vamp (7) onto the upper surface (2) of the sole (1) with the insertion of the tubular elements (8) of the vamp (7) between the tubular elements (4) of the sole (1); and the vamp (7) is detachably anchored to the sole (1) by inserting a wire (9) through the said tubular elements of the sole and the vamp after positioning of the vamp onto the sole. Said tubular elements of the sole (1) are placed according an open annular path, with two tubular elements (40, 41) disposed in correspondence of a respective end of the open annular path and communicating with the outside of the sole (1).

Abstract: Shoe with a separable sole and upper, wherein the sole (1) features an upper surface (2) on which a plurality of tubular elements (4) are applied so as to be distanced from one another with a predetermined value, wherein the upper (7) features a lower surface (6) on which a plurality of tubular elements (8) are applied so as to be distanced from one another with a predetermined value, wherein the upper (7) is associable to the sole (1) by positioning the lower surface (6) of upper (7) on the upper surface (2) of sole (1) and by inserting the tubular elements (8) of upper (7) among the tubular elements (4) of sole (1), wherein the upper (7) is reversibly anchored to the sole (1) by passing a thread (9) into the tubular elements of the sole and of the upper after positioning said upper on the sole, characterized in that said tubular elements applied on sole (1) are positioned in an open annular disposition with two tubular elements (40,41) each positioned in correspondence of a respective end of said open annul

Abstract: An attachment to replace existing landscaping trimmer heads and for mounting on new trimmers. The attachment includes specific structure for trimming grasses and weeds as well as structure for the removal of weeds unwanted grasses and unwanted shallow roots. The structure includes at least one pre-cut flexible trimming line that extends through the body member and a tapered bit member attached to the body member. The trimming line cuts and trims grasses and weeds and the tapered bit member has structure attached thereto for removal of weeds, unwanted grasses and unwanted shallow roots.

Abstract: An attachment for a landscaping trimmer for use in precise trimming and edging of landscaped areas. The attachment has bores through an elongated body member which are adjacent to the free end of the body member and perpendicular to its axis. Pre-cut pieces of trimming line are secured through the bores by at least one screw positioned against the portions of the pre-cut pieces which are centrally located within the body member. Integral with the body member and on Its free end, the present invention may have a spacer for lawn cutting, or pointed bits with various surface configurations to perform functions including, but not limited to, "drilling out" weeds and unwanted grass in and around planters, flower pots and flower boxes, as well as tearing out unwanted roots near the surface of the soil.
