Alpha Ordering - n, Or, Alpha Sort Ordering, this refers to a quirk of OpenGL (which the client uses) that causes two surfaces with alpha channels to be incorrectly rendered as if the farther one were nearer the viewer. This is often seen when parts of hair, skirts, and shoes flash in and out of existence as the transparent areas in the scene move in relation to each other. (Also called Alpha Flicker or Alpha Blink.)

Alt - n, "Alternate Account."

You can even design your own clothing and upload the textures to Second Life.

Coalesced Items - n, An item in your inventory that is a collection of many objects. When more than one object is returned to you from someone's land, the objects are often combined into one or more consolidated objects so that you won't receive a multitude of individual items. A coalesced inventory item appears in your inventory window with an icon that looks like a stack of cubes.

Local Coordinate System - n, A way of describing locations in the world relative to an object. The LCS of a particular object has its origin point <0,0,0> at its center, and the three coordinates correspond to the forward, left, and upward directions from the object's point of view. This is as opposed to the Global or World Coordinate System (GCS or WCS) in which everything is defined by absolute position in the world. For example, if a human lies down on the floor on their left hand side with their head facing North, then in GCS terms their head would be described as "West of their shoulders", since this is their literal position; in the person's LCS, their head would still be described as "above their shoulders," since this is its position relative to the rest of their body.

Local Lights - n, A feature built into newer graphics cards that helps render the glow of light sources very fast. Older graphics cards must simulate the glow of local lights using software algorithms, which can degrade performance on the client. This feature can be enabled/disabled in Preferences.

Mega-Prim - n, Prims that are larger than what is normally allowed, meaning that they have a dimension over 10m along one or more axes. At one time, megaprims could be created using tools invented by the libopenmv effort, but Linden Lab changed the server software to prevent new ones from being created. The existing megaprims were copied, transferred, and are still available today. Currently there is limited simulator support for megaprims. Their existence may cause simulator problems in some sims and so are not welcome everywhere. There is some movement within Linden Lab to support megaprims officially to some degree in the future.

Mentor - n, A resident volunteer working with Linden Lab of Second Life who teaches and guides other citizens.

Metaverse - n, A term for a virtual universe coined by Neal Stephenson in his 1992 science fiction novel Snow Crash. Stephenson's novel was an inspiration for Second Life.

Mono - An open source framework for executing .NET-compatible software on a wide range of operating systems. Linden Lab is currently integrating Mono into the Second Life server software. This will give several advantages: (a) allow LSL scripts that are compiled under Mono to execute much faster; (b) eventually will allow additional languages such as C# to be used for scripting in SL; (c) increased security will make it harder for scripts to crash a sim. The alternative to Mono is OSE, q.v.

Openspace Sim - n, A sim (region) for very light use with a dramatically reduced Prim Limit (750 prims) that operate four sims (regions) on a single sim processor. Designed by Linden Lab for creating open fields or seas, they are sold for about one quarter of the price of one ordinary Sim. Also called Void Sim. Also compare with Homestead (q.v.) regions.

Orbiter - n, A physics-based weapon that attacks a resident by rapidly pushing them upwards into the sky with a force that exceeds the amount of counterforce that normal Second Life flight can exert. Orbiters send their victims so far into the sky that it would take hours for them to fall back down in the normal way and/or their coordinates no longer fit within SL's world model. Normally, teleporting away or - in extreme cases - relogging will fix being orbited.

Outfit - n, A group of clothing items in a single folder in Inventory that can be dropped on the avatar to effect a fast change of appearance.



Packet Loss - n, Fragments of network data that get lost or mangled during transmission, for a wide variety of reasons. Reducing the Network Bandwidth in Preferences may reduce packet loss, with the trade-off that all data will be transferred more slowly.

Parcel - n, Section of land within one region that is treated as one lot. All land within a parcel shares the same owner, prim limit, About Land settings, ban lists, etc. A person can own more than one parcel in a region, and it is possible (though unlikely) for a parcel to be not contiguous. An estate consists of one or more regions (sims); a region (sim) consists of one or more parcels.

Particles - n, Two-dimensional sprites (graphic images that always face the viewer). Second Life's particle system allows a wide variety of particles, enabling residents to create burning fires, glistening waterfalls, vapor trails on jet fighters, tracers on bullets, the occasional macabre spurt of blood, floating hearts of affection, billowing smoke, rainbows, and much more.

Peak Usage - n, The maximum total amount of land a Second Life resident owned, at any one time, in a monthly billing period. To reduce possible exploitation of land ownership, Second Life bills land use fees based on peak usage; holding 4096 square meters for one minute costs the same as holding it for thirty days. Note that this amount always includes the resident's group contributions as well.

Permaban - n, v, The act of, and the result of, permanently banning someone.

Permissions - adj, Second Life's built-in "intellectual property" system. Abbreviated perms. Creators can choose whether subsequent owners of their creations can Copy, Modify, and/or Transfer that item. Creators who want to preserve their intellectual property rights usually limit one or more of these attributes. Every item in SL has permissions associated with it. The basic permissions are Modify, Copy, and Transfer. If you have Modify permissions on an item, this means that you can make changes to it in Edit mode. If you have Copy permissions on an item, this means that you can make copies of it for yourself-when you take it from your inventory, a copy of it remains in your inventory. If you have Transfer permissions on an item, this means that you can give it away (or sell it) to somebody else. Note that if you have Transfer but not Copy permissions, then if you give the item away, it will permanently remove it from your inventory. The term "Full Perms" means that you have all three of these basic permissions on an item.

Any activities, including monetary transactions, that occur on the Preview Grid are only temporary and are confined to the Preview Grid and have no effect on your inventory or L$ balance on the main grid.

Prim - n, Short for "primitive" the basic shapes that almost all objects in Second Life are made from. An object consists of a single primitive or multiple linked primitives. Prims are created, shaped, and textured via the Edit window or by scripts. The basic Prim types are: Box, Cylinder, Sphere, Ring, Tube, and Torus. Objects are made of one or more prims (sometimes hundreds!). Every parcel of land has a limit on how many prims it can hold (a 512-square-meter parcel of land can have 117 prims), which is why many builders try to keep their objects "low prim."

Prim Flicker - n, The condition where two textures seem to overlap and shift one over the other as you move around them. Prim flicker is caused by badly positioned overlapping sections of prims.

Prim Hair (or eyelashes, or fingernails.) - n, Hair made from twisted and textured prims. You can generate a basic non-prim hairstyle with the avatar appearance sliders, but a wig made of prims looks much more realistic.

Prim Limit - n, The number of prims that can be rezzed on a given parcel of land at any one time.

Prim Sculpture - n, v, Use of overlapping, modified prims to create artistic, realistic, and/or organic shapes. The term "Prim Sculpture" originated well before Sculpties were introduced, to describe skill at working around the fact that custom prim shapes were not available at that time; thus, Sculptie Prims are (paradoxically) not generally referred to as Prim Sculptures.

Prim Taxes - n, A now discontinued feature of Second Life. Before Second Life 1.2, the amount of prims residents could have in world was limited by "taxes" on each prim deducted from the Avatar's account when prims were rezzed.

Prim Torture - 1. v, A method for adjusting settings of a Prim which are not normally accessible, by switching the prim between different types. For example, you can set a prim to type Tube, adjust the Profile Cut setting, and then set the prim to type Box.

Currently, a "ruthed" avatar is represented by a soft particle cloud. 2. v, Being "ruthed" is Second Life slang for appearing in the shape of the default SL Avatar (normally due to server lag or dropped packets). To de-ruth yourself, go into Appearance mode, make a very minor change, and then save that change, or log out and back on, or change shapes, or do any other operation that triggers the shape information to be downloaded fresh from the sim.

RX Team - n, "Resident Experience Team," a group within Linden Lab responsible for improving the new user experience. Also see SL-UX.

Sim State - n, A snapshot of a region, including all the objects, terrain, scripts, and other things in a region. Sim states are periodically saved and backed up by each sim server and used to recover a region after a crash. Alternatively spelled "simstate."

Simulator Object Bonus - n, A special setting on Private Islands which allows the Prim Limit on some parcels to be increased. However, the sim owner must "pay back" the extra prims by leaving other areas of the sim empty.

Sit - v, To sit on something, right-click the object then choose "Sit" from the pie-shaped menu. Sometimes that slice of the pie menu might say something other than Sit (like Relax, Cuddle, or Dance). This will access an animation that is embedded in the object that you clicked on. The same process is used to run many animations in SL -- not just to sit down. Also see Pose balls.

Sit Target - n, The coordinates, as offsets from a prim's center, and the local rotation of where an avatar will be positioned when seated on the prim. Newly created prims have a default sit target and only a script can change it. Once changed by a script, the modified sit target will remain in effect even if the script is removed.

Skin - n, A texture image that replaces the default skin of your avatar. Cannot (usually) be adjusted by the appearance sliders, but looks much better than the default skin.

Skybox - n, Any building located up in the sky, instead of on the ground.

SL - n, see Second Life.

SLED - n, The mailing list for Second Life educators and those interested in the educational potential of Second Life.

SLGOGP - n, "Second Life Grid Open Grid Protocol." See OGP.

Sliders - n, Controls for customizing Avatar appearance and clothing. These sliding settings levers in Appearance mode (right-click on Avatar and select "appearance" to access) change values for avatar and clothing mesh. As an example, foot size can be altered from tiny to large on one slider, rounded to pointy toes on another, thin to thick platforms on another.

SLT - "Second Life Time." The time zone corresponding to the local time at the Linden Lab offices in San Francisco. Linden Lab now refers to Pacific Daylight Time (PDT) and Pacific Standard Time (PST), but the term SLT is commonly used in-world by residents

SLURL - n, A type of weblink that launches the Second Life client and teleports you to the location indicated via the website.

SL-UX - n, Abbreviation for the Second Life User Experience. Refers to the mailing list and activities of the Rx Team, q.v.

Spam - n, An unsolicited instant message, notecard, texture, group invite, animate request, or object sent to multiple people. This can be sent by another player, or by an object containing a script.

Statistics Bar - n, A window of detailed performance data that appears on the upper right corner of the user's screen, enabled with Ctrl-Shift-1 or View->Statistics Bar. The data can help identify the source of performance problems in the client or simulator.

Stipend - n, The money given to a resident by Linden Lab on a weekly basis. Premium accounts receive Stipends (300L$/week), though some older accounts have been grandfathered in under previous stipend programs.

Streaming Music/Video - n, Music and video that may be heard and viewed on a parcel. Each parcel may have one video and one audio stream set at any one time. Streams are specified as URLs to files or streaming servers on the Internet. With the proper permissions, an avatar can manually specify the URL of the streaming audio and video in the Media tab of Preferences, or by using a script to set those fields.

Studio Icehouse - n, An engineering group in Linden Lab focused on the architectural underpinnings of Second Life.



Target Omega - n, One of two techniques used by LSL scripts to make an object appear to spin on one or more of its axes. Target omega spinning is computed and rendered by the client. The other way to make an object spin is physical rotation, which is managed by the server side.

Tekkie-Wiki - n, Derogatory term for users with advanced technical knowledge or experience of Second Life, who are alleged to be unable to empathize with those who lack similar knowledge.

Telehubs - n, A now discontinued feature of Second Life. Telehubs were centralized teleport locations in Second Life. Before SL version 1.7, point-to-point teleporting was not enabled. Teleports all landed at the nearest Telehub to the destination point. From there, you had to fly to your destination. Most Telehubs were eliminated, but some were converted into Infohubs.

Teleport - 1. v, To transport oneself instantly to another location. In Second Life, you can teleport by clicking on a landmark, using the map window, responding to a teleport request, or by selecting "teleport home" from the World menu. Abbreviated TP. Also used as a verb meaning offer me a teleport ("Oh--that sounds cool; TP me over please."). 2. n, An offer to teleport an individual to your location, e.g., "please send me a TP."

Temporary - adj, Objects marked in Second Life as not being permanent. When an object is marked as temporary, it will be deleted a few minutes after use. This is great for things like gun projectiles, dominos, or beach balls that might get away from you, disappear somewhere, or end up on no-script land (where their script would prevent them from deleting themselves).

Terms of Service - n, The set of rules that all residents agree to follow while using Linden Lab services or products, and the consequences of violating those rules. Abbreviated TOS. Also see Community Standards.

Terraform - v, To change the shape and elevation of land. Most Mainland sims are limited to ± 4 meters terraformability. Land on Private Estates can be terraformed up to ± 100 meters depending on settings by the Estate Managers.

Texture - n, An image or graphic uploaded to Second Life for application to the surface of an object or to clothing. Textures can be purchased or found for free in-world, or created in third-party graphics programs and uploaded to Second Life for L$10 per image. You can double-click on a texture in your inventory to see it, or you can drag it onto a side of prim to "paint" it with that texture. "Texture" is also the name of one of the tabs in Edit mode. Go to the Texture tab to make changes to how the texture is placed on a prim if you have Modify permissions.

Tier - 1. n, The monthly land "tax" you pay to either Linden Lab (on the mainland) or to a private island owner to own land. The more land you own, the higher your monthly Tier fees, but the less you pay per square meter (m2). Premium members get 512 m2 of free mainland tier. 2. n, One of the levels of land ownership (and associated land use fees).

Tier Up - v, To raise the level of tier you pay monthly to Linden Lab. Tiering up allows you to own more land and/or make a higher tier contribution to a Group.

Time Dilation - n, A simulator tries to update all the physics effects in a sim 45 times a second. When the sim cannot make these calculations fast enough, time seems to slow down. Avatars, vehicles, and other things move more slowly than normal. The time dilation is shown in the Statistics Bar, and can be read by scripts.

Tiny - n, An extremely small Avatar, usually a furry, designed to resemble an animated stuffed animal.

Tiny Prim - n, See Micro Prim.

Tooltip - n, The information that appears when a mouse pointer is moved over an item or avatar. Slide the mouse arrow (without pressing any mouse buttons) over the item and the tooltip will appear, telling you the name or cost of an item, or the name of an avatar.

Tortured Prim - n, A prim that that has been modified into a shape that is normally not possible. See Prim Torture.

TOS - n, See Terms of Service.

Town Hall - n, A meeting where a senior Linden addresses and takes questions from residents. Town Halls are usually conducted via voice.

TP - see Teleport

Traffic - n, A Linden Lab generated measure of how many avatars frequent a parcel of land and how long they stay. Higher traffic results in a higher placement in the "Places" search (see Camping).

Triage - n, In Second Life, refers to several weekly meetings of Linden Lab developers and residents to discuss the priorities of fixing outstanding bug reports and enhancement requests. Bug triages occur in SL life in conjunction with the office hours meetings of several Linden Lab employees.

TTYL - "Talk To You Later"

TY - "Thank You!"


U - V

UUID - n, Globally unique identifier assigned to each item in the SL Asset Server database. Every avatar, object, texture, clothing item, body part, notecard, sound, animation, snapshot, gesture, etc. has its own UUID. Also known as a Key.

UX - n, "User Experience," See SL-UX.

VBO - n, "Vertex Buffer Objects." This is a feature in most newer graphics cards that can substantially improve client rendering performance, but may cause problems with some hardware. It can be enabled/disabled in Preferences.

Vehicle - n, A scripted object whose movement you can control. Typically, a resident will sit on/in the vehicle and use it as a form of transportation. Vehicles include cars, airplanes, hoverboards, boats, UFOs, and much more.

Vendor - n, A scripted object that designed to sell objects, clothing, or other items to residents. Many brands of vendors are networked and operate of a central server.

Void Sim - n, See Openspace Sim.

Voting Machine - n, A machine that is usually marked "Vote" that allows a visitor to register approval for the owner's build. Voting machines were once tied into the now-discontinued SL Dwell system where money was awarded to the owner of the property according to how many votes occurred the previous day.

VTeam - n, The name of the internal group of Linden Lab employees who coordinate the volunteer programs throughout Second Life.

VW - "Virtual World"


W - X - Y - Z

WarpPos - n, A scripting technique used in teleporters. This allows avatars to be teleported farther and faster than other techniques.

Wear - v, To attach prim clothing or other items to your avatar. You can wear an item by dragging it from inventory onto your avatar, or right click the item in inventory and choose "Wear." Choose "Add to Outfit" to wear all the items in an inventory folder. The creators of wearable items typically set a default body part or attachment point for the item which you can change if necessary. To stop wearing an item, right click it and choose "Detach" or choose Edit->Detach Object if it is prim-based, or right click your avatar and choose "Take Off" or click Edit->Take Off Clothing to remove a non-prim item.

WebKit - n, Linden-funded replacement for Mozilla as the in-world browser embedded in the viewer.

Welcome Area - n, Abbreviated WA, a Linden Lab-owned and designed information and social area. The two largest Welcome Areas (Ahern and South) are located at the intersection of four sims to support a large number of people, and are surrounded by Linden-owned greenspace. Some new players first spawn at one of the Welcome Areas after leaving Orientation Island or Help Island.

Whisper - n, Speech (usually by objects containing scripts) that is audible only within a 10 meter radius from the object. Compare with regular chat (20m radius), shouting (100m radius) and Region Say (sim-wide).
