Biblijske priče o Božjem pozivu često slijede isti obrazac: čovjek dobije zadatak, uplaši se ili mu se opire, Bog ga uvjerava, a čovjek ga na kraju izvrši. Mojsije se kod gorućeg grma smatrao nedoraslim pozivu, Gideon je tražio znakove, Jona je pobjegao od zadatka, a Ananija se bojao otići Savlu. Ipak, svi su na kraju poslušali. To ne znači da su svi kojima se Bog ukazao ostali poslušni. Salomonu…
The 3-2-1-1-0 rule is a practical backup strategy for reducing the chance of losing important data such as databases, documents, or photos: 3 copies of the data in total. 2 different storage types or media. 1 copy stored off-site. 1 copy kept offline or immutable. 0 backup errors after regularly testing that restores actually work. The point is to make sure a single hardware failure, deletion,…
An agent harness is the software layer around an LLM that turns the model from a text generator into an agent that can repeatedly observe, act, verify, and continue toward a goal. A useful mental model is: Agent = Model + Harness The model provides the reasoning capability. The harness controls the environment in which that reasoning operates: tools, context, execution loop, permissions, state,…

Kršćansko učenje o uskrsnuću ne govori samo o besmrtnosti duše, nego o uskrsnuću cijelog čovjeka. Prema Novom zavjetu, Isus je uskrsnuo tjelesno: njegovo tijelo bilo je stvarno i prepoznatljivo, ali preobraženo i više nije bilo podložno smrti i raspadanju. Iz toga proizlazi nada da će i ljudi uskrsnuti kao iste osobe, ali u proslavljenom i neraspadljivom stanju. Kad Isus kaže da će ljudi nakon…
Question to explore: why can German sound “sharp” to some listeners? Possible angles: consonant clusters, fricatives, stops, rhythm, prosody, cultural stereotypes, and how perception changes with familiarity.
Stacked branches are a chain of small, dependent Git branches where each branch starts from the previous branch instead of directly from the main branch. On GitHub, each branch can have its own pull request targeting the branch below it. This keeps reviews small and focused, but the stack should be merged from the bottom up, with dependent branches rebased when earlier branches change.
Juda i Isusov poziv Isus je Judu izabrao među Dvanaestoricu, dao mu mjesto u zajednici i nije ga javno odbacio ni kada je izdaja postala neposredna. To se može tumačiti kao: Isusova ljubav prema grešniku do posljednjeg trenutka ostavljanje prostora Judi da promijeni odluku pokazivanje da neprijatelja ne treba odmah uništiti ili poniziti svjesno prihvaćanje vlastite smrti Ali kritički ostaje…
Smisao filma „Gori vatra“ je prikaz poslijeratne Bosne kao društva koje pokušava izgledati normalno i pomireno, dok ispod površine još gore rat, trauma, kriminal, mržnja i neriješeni odnosi. Radnja se odvija u Tešnju, gdje se stanovništvo priprema za navodnu posjetu američkog predsjednika Billa Clintona. Zbog te posjete svi moraju na brzinu napraviti sliku „uspješnog multietničkog grada“: sakriti…

BFF means Backend for Frontend: an API layer tailored to one frontend or client experience. REST is a resource-oriented API style that exposes reusable endpoints around domain resources. Core difference # REST usually exposes general resources such as users, orders, products, or documents. A frontend combines those resources into the shape needed by a page or workflow. A BFF exposes endpoints…
Diogenes of Sinope was the most famous Cynic philosopher. His philosophy was not a theoretical system like Plato’s or Aristotle’s. It was a radical way of living. Core idea # Diogenes believed that most people are enslaved by fake needs: money, status, reputation, luxury, social approval, politics, and comfort. For him, the good life meant living simply, needing little, obeying nature,…

Goal # Build several unrelated applications quickly with Django and a frontend, host them economically on one server, and preserve the option to move genuinely slow components to Go, Rust, or another runtime later. Core architectural decision # Start with a modular Django monolith, not microservices. Organize code by business domain and keep important workflows behind explicit inputs and outputs.…
GeoPackage is an open, SQLite-based file format for storing geospatial data, including vector features, raster tiles, and related metadata, in a single portable .gpkg file. Because it is built on SQLite, a GeoPackage is both a file and a small relational database. It can store tables, indexes, metadata, coordinate reference system information, and spatial data in one portable artifact. The main…
Heidegger focuses on Being, mortality, authenticity, and the problem of living consciously instead of drifting through inherited routines. Core idea # Thinking about death is not meant to be morbid. It is meant to make life more serious. Mortality forces the question of whether a person is living from their own understanding, or merely copying what “one” does. For Heidegger,…
Uskrsnuće i žrtva # U kršćanskoj logici, bez uskrsnuća bi Isus prvenstveno ostao nepravedno ubijena žrtva ili moralni mučenik. Mogao bi i dalje biti iznimno plemenit, ali njegova smrt sama po sebi ne bi dokazala da je njegov put istinit niti da je smrt pobijeđena. Zato Pavao kaže da je vjera prazna ako Krist nije uskrsnuo. Ljudi su se kroz povijest žrtvovali za narode, ideologije, obitelji,…
Kierkegaard focuses on the individual, faith, anxiety, despair, responsibility, and the leap of faith. His point is not manifestation or positive thinking. It is that a person must choose and commit under uncertainty. Faith is not certainty before action, but the decision to live seriously without having complete proof. Who he was # Søren Kierkegaard was a nineteenth-century Danish philosopher and…
Legacy of Kain uses gothic fantasy to question truth, destiny, divinity, and whether a godlike authority should be trusted simply because it presents itself as holy. Core idea # The series is not only about vampires, souls, and revenge. It is also about the collapse of inherited certainty. Characters discover that what looked like cosmic order may be manipulation, and that the difference between…

Modern philosophy often focuses on the human person, existence, mortality, identity, technology, society, and the loss of traditional certainty. Core idea # Twentieth and twenty-first century philosophy is shaped by modern crises: industrial war, secularization, Darwinism, political catastrophe, technology, and the weakening of inherited religious and metaphysical frameworks. When old certainties…
Newspeak is the fictional constructed language in George Orwell’s Nineteen Eighty-Four , designed by Oceania’s ruling Party to restrict thought by restricting language. Purpose # Newspeak is built on the idea that language shapes what people can think. By shrinking vocabulary, simplifying grammar, and removing nuance, the Party aims to make rebellious or unorthodox thought impossible…
ORMs make relations feel like objects inside objects. SQL does not work that way. In SQL, a table row only has columns. Relations are expressed with IDs: trips.owner_id -> users.id trip_days.trip_id -> trips.id activities.trip_day_id -> trip_days.id The mental shift is moving from object navigation to explicit data access. ORM thinking # In Django or another ORM, related data often feels like it…
Peter Singer is a utilitarian philosopher focused on reducing suffering and taking moral consequences seriously. Core idea # Singer argues that moral concern should not stop at personal preference, national borders, species membership, or social convenience. If suffering can be reduced, and the cost of helping is reasonable, then there is a strong moral reason to act. This connects his work on…
PostgreSQL is a durable, extensible relational database that often works well as the primary data store for application systems.

Religious belief is shaped not only by arguments, but also by family, culture, community, need for meaning, and early psychological experience. Core idea # Some people continue to believe and go to church because religion is not only a set of propositions. It can also be a language of trust, belonging, moral orientation, ritual, memory, and identity. For others, religious belief is harder to…

Herdr is a terminal workspace tool, similar in spirit to tmux, that supports mouse-controlled panes, tabs, persistent sessions, and agent workflows where agents can inspect panes through the Herdr integration.
People do not begin life from equal positions. Some start with family, money, stability, confidence, and social support. Others spend years trying to catch up. Core idea # This inequality can be understood through contingency: people are thrown into conditions they did not choose. Family, class, country, health, temperament, and early emotional security shape the field before personal choice…
Wittgenstein’s later philosophy argues that meaning comes from use, not from a fixed hidden essence behind words. Core idea # Words make sense inside language games: practical forms of life where people share habits, expectations, and social rules. A word does not carry one complete meaning everywhere. Its meaning depends on how it is used. Croatian at home, English in Norway, and British…
