coordination engine
for - definition - coordination engine - The coordination engine is - the underlying pattern of how people coordinate their actions with one another and - the material flows around them, through space and time. - It’s about the economy in a wide sense: about how human activities link up with one another. - An economy is basically a pattern of coordination of human agency over space and time.
-
purification engine
for - definition - purification engine - a purification engine, such as the Postfaustian or Postmodern metamemes, are cultural re-organizations of a particular mode of extraction, but they do not reinvent the mode of extraction itself.

ir bekennen uns zur Notwendigkeit vonInnovation und neuen Technologien zur Be-waltigung der Herausforderungen unsererZeit, insoesondere bei der Mobilitat. Diesgilt auch fur Antriebstechnologien wie denVerbrennungsmotor, der fur den WohlstandEuropas von eminenter Bedeutung ist
Über den Verbrennungsmotor heisst es, dass er „für den Wohlstand Europas von eminenter Bedeutung ist“. Dass er eine der Hauptursachen für die globale Erhitzung ist, bleibt unerwähnt, auch nicht, dass er ineffizient ist und dass das Festhalten am Verbrennungsmotor die Wettbewerbsfähigkeit der europäischen Industrie schwächt.

Increasingly, our partners are interested in building collections - or connecting to - credentials that they don’t own, issue, or offer to show learners the full pathways of learning opportunities that they can pursue.
Example of how this gets operationalized: There will be platforms (think Naviance on big data and personalized data steroids) that will help Learners discover right fit opportunities based in part on the credentials they already have. There will be savvy institutions connecting to others' credentials so as to increase the likelihood that Learners discover those institutions' program offerings. This will be akin to a sort of skill-based SEO approach as a recruitment/admissions strategy.

Examples of these sources would include an established digital walletprovider, or an exhaustive catalogue of digital credentials that are available, such as the repositoryhosted by Credential Engine. Having the curricular data source, which has a connection to the parsingcompanies, also create a connection to credential information opens up a connection, albeit anindirect one, between the non-degree credential information and the parsing activity. Instead ofreceiving just a course name from the resume parser, the intermediary can also receive a non-degreecredential identifier that is sent to the credential data source to look up and return skills information
Opportunity to go deep here. Bread crumb is to check out the issuer directory with Credential Engine, where they are inviting institutions to publish details about their credentials in a standardized format (CTDL) that will hopefully one day be consumed by connections like those hinted at here.

- Epstein's organization is building two technologies that assist in combating these problems:
- passively monitor what big tech companies are showing people online,
- smart algorithms that will ultimately be able to identify online manipulations in realtime:
- biased search results,
- biased search suggestions,
- biased newsfeeds,
- platform-generated targeted messages,
- platform-engineered virality,
- shadow-banning,
- email suppression, etc.
- Tech evolves too quickly to be managed by laws and regulations,
- but monitoring systems are tech, and they can and will be used to curtail the destructive and dangerous powers of companies like Google and Facebook on an ongoing basis.

- summary
- research that shows how search engines can actually bias towards a political candidate in an election and tilt the election in favor of a particular party.
-
In our early experiments, reported by The Washington Post in March 2013, we discovered that Google’s search engine had the power to shift the percentage of undecided voters supporting a political candidate by a substantial margin without anyone knowing.

- stats begin
- search results favoring one candidate
- could easily shift the opinions and voting preferences of real voters in real elections by up to 80 percent in some demographic groups
- with virtually no one knowing they had been manipulated.
- stats end
- Worse still, the few people who had noticed that we were showing them biased search results
- generally shifted even farther in the direction of the bias,
- so being able to spot favoritism in search results is no protection against it.
- stats begin
- Google’s search engine
- with or without any deliberate planning by Google employees
- was currently determining the outcomes of upwards of 25 percent of the world’s national elections.
- This is because Google’s search engine lacks an equal-time rule,
- so it virtually always favors one candidate over another, and that in turn shifts the preferences of undecided voters.
- Because many elections are very close, shifting the preferences of undecided voters can easily tip the outcome.

We now have the capacity to ensurethat all possible pathways – andthe essential information about allthe providers, credentials, skills,assessments, quality indicators,outcome measures, transfer values,and links to job skills critical tounderstanding and building thosepathways – can be made fully open,transparent and interoperable sothat a new generation of tools tocustom pathways to meet everyone’sindividual need
There is a lot in this little paragraph, and a big point to not miss is the call out of "individual need." There will be dashboards and other tools that purport to serve learners/earners with comprehensive data about the possible pathways that are open to their successful futures. A harmful that we can anticipate many falling into however, will be generalized data that fails to leverage "nearest neighbor" practices that provide users with data based on the outcomes experienced by people with shared characteristics to their own. For example, if a specific pathway has great outcomes that are disproportionately enjoyed by White males under 45 who already work in that industry, then the generalized data may be misleading to a career-changing Black woman in her early 60s who is investigating the next steps in her journey..

from experience, gamemaker does a phenomenal job with making simpler games that perform how you want it to, without having to worry about extra things that may not pertain to the kind of project you wish to make. you can think of gamemaker as more of a blank slate, and you add what you need versus unity being more general and having a lot of components and tools that you most likely won't have to use.

Open Knowledge Maps, meanwhile, is built on top of the open-source Bielefeld Academic Search Engine, which boasts more than 270 million documents, including preprints, and is curated to remove spam.
Open Knowledge Maps uses the open-source Bielefeld Academic Search Engine and in 2021 indicated that it covers 270 million documents including preprints. Open Knowledge Maps also curates its index to remove spam.
How much spam is included in the journal article space? I've heard of incredibly low quality and poorly edited journals, so filtering those out may be fairly easy to do, but are there smaller levels of individual spam below that?

Algospeak refers to code words or turns of phrase users have adopted in an effort to create a brand-safe lexicon that will avoid getting their posts removed or down-ranked by content moderation systems. For instance, in many online videos, it’s common to say “unalive” rather than “dead,” “SA” instead of “sexual assault,” or “spicy eggplant” instead of “vibrator.”
Definition of "Algospeak"
In order to get around algorithms that demote content in social media feeds, communities have coined new words or new meanings to existing words to communicate their sentiment.
This is affecting TikTok in particular because its algorithm is more heavy-handed in what users see. This is also causing people who want to be seen to tailor their content—their speech—to meet the algorithms needs. It is like search engine optimization for speech.

The key thing about the REST approach is that the server addresses the client state transitions. The state of the client is almost totally driven by the server and, for this reason, discussions on API versioning make little sense, too. All that a client should know about a RESTful interface should be the entry point. The rest should come from the interpretation of server responses.

A TSet stores a collection of unique values, similar to std::set. With the AddUnique and Contains methods, TArrays can already be used as sets. However, TSet has faster implementations of these operations, at the cost of not being able to use them as UPROPERTYs like TArrays. TSets are also do not index their elements like TArrays do.

I wonder if these would be good for storing metadata with prototype support (see near the end of Prototype in Game Programming Patterns).

Actor
Should be AActor
-
Object
Should be UObject?
-
UE_LOG(LogTemp, Log, TEXT("Found UObject named: %s"), *CurrentObject.GetName());
Should be:
UE_LOG(LogTemp, Log, TEXT("Found UObject named: %s"), *(CurrentObject->GetName())); -
Using object iterators in PIE (Play In Editor) can lead to unexpected results. Since the editor is loaded, the object iterator will return all UObjects created for your game world instance, in addition to those that are just being used by the editor. Actor iterators work in much the same way as object iterators, but only work for objects that derive from AActor. Actor iterators do not have the problem noted below, and will only return objects being used by the current game world instance.
-
MyUObject
Shouldn't this be
UMyObject? -
You'll first notice the inclusion of "MyClass.generated.h". Unreal will generate all the reflection data and put it into this file. You must include this file as the last include in the header file that declares your type.
-
To use a UStruct, you do not have to extend from any particular class, you just have mark the struct with USTRUCT() and our build tools will do the base work for you. Unlike a UObject, UStructs are not garbage collected. If you create dynamic instances of them, you must manage their lifecycle yourself. UStructs are meant to be plain old data types that have the UObject reflection support for editing within the Unreal Editor, Blueprint manipulation, serialization, networking, etc.
-
Use inheritance when you want to customize an existing AActor or UActorComponent. Use composition when you want many different AActor types to share the functionality.
At this high level, it almost sounds as if components are a way to implement mixins in C++, though perhaps more loosely coupled in terms of class type.
-
UActorComponents have their own behaviors and are usually responsible for functionality that is shared across many types of AActors, e.g. providing visual meshes, particle effects, camera perspectives, and physics interactions. While AActors are often given high-level goals related to their overall roles your game, UActorComponents usually perform the individual tasks that support those higher-level objectives. Components can also be attached to other Components, or can be the root Component of an Actor. A Component can only attach to one parent Component or Actor, but it may have many child Components attached to itself. Picture a tree of Components. Child Components have location, rotation, and scaling relative to their parent Component or Actor.
-
Unreal Engine calls the creation of an AActor at runtime spawning. Spawning an actor is a bit more complicated than creating a normal object in the game. The reason is that an AActor needs to be registered with a variety of runtime systems in order to serve all of its needs. The initial location and rotation for the actor need to be set. Physics may need to know about it. The manager responsible for telling an actor to tick needs to know. And so on. Because of this, we have a method devoted to the spawning of an actor, UWorld::SpawnActor(). Once that actor is spawned successfully, its BeginPlay() method is called, followed by Tick() the next frame.

AActors have their own behaviors (specialization through inheritance), but they also act as containers for a hierarchy of UActorComponents (specialization through composition). This is done through the AActor's RootComponent member, which contains a single UActorComponent that, in turn, can contain many others. Before an AActor can be placed in a level, that AActor must contain at least a USceneComponent which contains the translation, rotation, and scale for that AActor.

An AActor is an object that is meant to be part of the gameplay experience. AActors are either placed in a level by a designer or created at runtime via gameplay systems. All objects that can be placed into a level extend from this class. Examples include AStaticMeshActor, ACameraActor, and APointLight actors. AActor derives from UObject, so enjoys all of the standard features listed in the previous section. AActors can be explicitly destroyed via gameplay code (C++ or Blueprints) or via the standard garbage collection mechanism when the owning level is unloaded from memory. AActors are responsible for the high-level behaviors of your game's objects. AActors are also the base type that can be replicated during networking. During network replication, AActors can also distribute information for any UActorComponents owned by that AActor that require network support.

Now that our designers can call our C++ code, let us explore one more powerful way to cross the C++/Blueprint boundary. This approach allows C++ code to call functions that are defined in Blueprints. We often use the approach to notify the designer of an event that they can respond to as they see fit.

That is, the human annotators are likely to assign different relevance labels to a document, depending on the quality of the last document they had judged for the same query. In addi- tion to manually assigned labels, we further show that the implicit relevance labels inferred from click logs can also be affected by an- choring bias. Our experiments over the query logs of a commercial search engine suggested that searchers’ interaction with a document can be highly affected by the documents visited immediately be- forehand.
