Rezultate backend development

Salut! A trecut ceva timp de la ultima postare referitoare la revizuirea strategiei comunitatii: click aici. A venit si 2026, iar odata cu asta am decis sa publicam o parte din rezultatele noastre pe partea de backend dev. Pentru asta, amintim in continuare serverele de discord administrate de noi, intrucat o buna parte din rezultatele muncii noastre se remarca acolo. Pe langa asta, regasiti o alta parte din rezultatele muncii noastre pe serverele oficiale de CSGO si CS2 ale comunitatii. Restul se afla in backend.

Limbaje si performanta software

In ceea ce priveste alegerea limbajelor de programare, am mers pe favoritele noastre: C, C++, C#, Java, Go, Python. Ce inseamna asta? Ei bine, in situatiile unde avem nevoie de performanta bruta, am ales C/C++. In rest: C#, Java si Go pentru software medium-sized to large-sized, iar Python (si Bash) pentru scripting. Adaug totusi urmatoarea mentiune: desi am inlocuit o buna parte din scripturile de Python (si Bash) cu scripturi scrise in Go datorita performantei, nu am renuntat complet la limbaje interpretate deoarece sunt utile in functie de use-case, iar un SysAdmin/Dev bun se foloseste de tot ce are pentru a livra rezultate exceptionale in functie de cerintele specifice pe fiecare caz. Uneori e importanta reducerea timpului de development, alteori e importata performanta chiar si la programe micute.

 

Cat despre modul in care tratam partea de software development si performanta, aici avem o multime de lucruri de zis, dar ne rezumam la cele esentiale. Se remarca diferente relevante in cazul proiectelor open-source lansate de fairside fata de proiectele closed source. De ce? Pentru ca proiectele closed source trebuie sa respecte exigentele noastre incat sa ruleze exact asa cum dorim in productie, in general pe infrastructura noastra. Comparativ cu asta, in proiectele open-source fiecare e liber sa altereze codul in functie de nevoile individuale.

 

Asadar, in proiectele closed source prioritizam:

• limbaje de programare compilate, cat mai apropiate de assembly ca nivel de abstractizare
• reducerea alocarilor de memorie (in principiu reduced stack allocs si zero or close to zero heap allocs)
• stack allocs instead of heap allocs where suitable
• high throughput and low latency
• eliminare dependente redundante
• coding from scratch in anumite cazuri in locul librariilor mainstream care acopera nevoi generice
• code concurrency with sharding (atomicity or mutual exclusion in functie de caz)
• RAM storage with fine-tuned evict policy
• backup and data recovery measures
• automatizari cat mai multe
• our own custom linux commands for SysAdmin activity
• CLI arguments instead of JSON files
• micro-optimization techniques
• lower-level networking and linux-specific tricks
• OS-level metrics (e.g., netstat, /proc/net/udp) for overall packet reception health and loss detection
• buffer pools and pointers where suitable
• code readability and maintainability

 

Mentiuni importante backend dev

In aceasta postare regasiti doar o parte din rezultatele eforturilor noastre in urma procesului de backend development. De ce? Pentru ca nu consideram ca e necesar sa publicam absolut tot ce exista in backend. Cu toate astea, informatiile publicate deja mai jos ofera un overview suficient de bun incat sa arate ceea ce am putut realiza cu efortul cumulat al perioadei anterioare.

 

Am realizat destul de multe alternative la solutiile software comerciale si open-source regasite pe Internet, iar pe langa asta am dezvoltat aplicatii proprii pe baza ideilor noastre, ajungand la concluzia ca putem inova in paralel daca tot cautam sa acoperim nevoile fundamentale ale gamerilor nostri. In plus, focusul nostru a mers in principiu catre dezvoltarea de software - nu doar partea de linux management - fapt care rezultat in rezolvarea multor probleme intalnite atat de noi, cat si de managerii de servere si jucatori. Asta nu a facut decat sa ne bucure, intrucat am obtinut ce am cautat.

 

Se remarca utilizarea de cuvinte/prefixe cheie, precum "automation", "auto", "performance", "concurrency", "atomicity", "mutual exclusion", "sharding". Daca doriti explicatii suplimentare, accesati discordul comunitatii unde regasiti detalii pe canalul #fairside-news odata cu fiecare implementare realizata de noi.

 

O alta mentiune importanta este existenta etichetei PLANNED la anumite elemente din listele de mai jos, fapt care arata ce alte lucruri avem in plan pentru perioada imediat urmatoare. Cat despre restul caracteristicilor si solutiilor software: sunt complet functionale si ruleaza deja in productie, insa n-am mai adaugat eticheta DONE pentru a evita repetitia.
