Migrating mission-critical payments at Nubank to Amazon Aurora PostgreSQL

Nubank, a digital banking platform with approximately 135 million customers in Brazil, Mexico, and Colombia, faced challenges with its payment infrastructure due to inefficiencies in managing 7.5 TB of self-hosted PostgreSQL databases. Queries took over 13 minutes to execute, and replication lags exceeded four minutes during peak times. To address these issues, Nubank evaluated database solutions based on developer productivity, operational efficiency, performance reliability, and scalability. They selected Amazon Aurora PostgreSQL-Compatible Edition for its compatibility, performance improvements, and automated features. The migration to Aurora was facilitated by AWS Database Migration Service (AWS DMS), which minimized downtime and allowed for efficient transition. Post-migration, query performance improved significantly, with some queries executing up to 1,900 times faster, and overall end-to-end service latency decreased, enhancing customer experience. The migration resulted in a 25 percent cost reduction and ensured compliance with regulatory requirements.

‘The mid-2000s was the golden era of first-person shooters’: David Syzmankski, creator of Dusk and Iron Lung, discusses the games on his PC

David Szymanski is the creator of the game Dusk, which was released in 2018 and is inspired by classic first-person shooters like Doom and Quake. He initially developed short horror games before achieving success with Dusk. Szymanski has also created a submarine horror game called Iron Lung, which gained recognition after being adapted into a film by YouTuber Markiplier. He categorizes the history of first-person shooters into distinct eras, labeling the '90s as the silver age and the late '90s to mid-2000s as the golden age. He enjoys survival crafting games like The Forest and Subnautica but has not finished them. The oldest game installed on his PC is Doom, which he considers nearly the best FPS ever made. His most-played game on Steam is Counter-Strike 2, with 324 hours, and he has spent 186 hours on Elden Ring. Szymanski would never uninstall Infra, which he describes as his comfort game. He uses GIMP as an essential non-gaming software tool and has a relatively tidy desktop with nine icons.

Riot quickly backpedals on paid old-school skins in League of Legends Classic after backlash

League of Legends Classic has launched in Riot Games' public test environment, featuring a reduced champion roster and character builds from 2013 and earlier.

A user criticized the charging for classic skins, leading to over 6,000 upvotes on a subreddit post. In response, Riot Games announced that all classic skins would be unlocked and set as the default appearance. Riot explained their design choice to blend elements from various patches to accommodate diverse player preferences, as indicated by survey responses. As the mode moves to standard servers, Riot plans to make changes based on player votes regarding new patches.

Explore a snapshot of a massive million-by-million block Minecraft server

The 1,024,000² 2b2t World Download Project is a significant Minecraft archiving achievement, preserving approximately 13.7 TiB of compressed world data from the 2b2t server, including a million-by-million-block section of the Overworld, and smaller captures of the Nether and End dimensions. It is the largest available Minecraft world download, released via torrent. The project took over a year to develop, involving a team that utilized 28 bot accounts to collect data, resulting in four distinct captures of varying sizes. The project was led by a developer named crayne, with key contributors including Fuch, mahan, and Steve3. The code and documentation are available on GitHub, and the project incurred over ,000 in server rental costs. 2b2t, established in December 2010, is one of the oldest Minecraft servers, known for its unyielding map and challenging environment, having hosted over 1,000,000 players. The creators assert that no AI was used in the project and have licensed their work under CC0 for community accessibility.

The 3 Big Reasons Why GTA 6 Isn’t Coming To PC At Launch

In 2026, Grand Theft Auto VI is set to launch on PS5 and Xbox Series on November 19, but there is no announced release date for the PC version. Historically, every main entry in the Grand Theft Auto series has been delayed on PC, with previous titles typically releasing several months after their console counterparts. The trend indicates that GTA VI may also experience a similar delay. Rockstar prioritizes console development due to strategic partnerships and market dynamics, which allows for a more refined gaming experience. Although PC gamers must wait for the release, they often receive a superior version with improved graphics and performance. In 2026, the performance of current-generation consoles has narrowed the gap with PCs, leading to speculation about a potentially shorter delay for the PC version of GTA VI.

As a PC Gamer Who Hasn’t Bought a Disc in a Decade, I Think PlayStation All-Digital Future Was a Long Time Coming – but There Are Still Reasons To Be Wary

Rockstar has decided not to release a physical version of its upcoming game, GTA 6, while Sony plans to stop producing discs for PlayStation consoles by January 2028. The gaming community has reacted strongly, but it is unlikely that either company will change its decision. The transition to a discless future is seen as inevitable. In the PC gaming sector, physical discs have largely become obsolete, with platforms like Steam dominating the market. The initial skepticism towards Steam has shifted as it became a reliable digital marketplace, leading to a decline in physical media. The absence of physical discs raises concerns about consumer autonomy, pricing, and game preservation, as digital ownership is often limited to licenses rather than full ownership. The shift away from physical media has been ongoing, with modern gaming increasingly reliant on digital downloads and updates.
