Scrawl turns hand-drawn sketches into playable games using Gemma 4

0
·9 views

A student created Scrawl, a web app that converts a photo of a doodle, or a drawing made on screen, into a playable game within seconds. Gemma 4 identifies the drawing type, such as platformer, maze, or race track, and extracts the position of each element like platforms, coins, and goals. The app then checks the model's output and fills in missing pieces, such as a floor or goal, so every level loads reliably. Users with a free account can save their levels to replay later and share them with friends via a link. The project was built for the MLH x DEV Writing Challenge, and the creator has published the code on GitHub.

Palo Alto PAN-OS flaw CVE-2026-0321 allows unauthenticated denial-of-service via dataplane traffic

Palo Alto Networks released a batch of security advisories in mid-October 2026, which CERT-FR grouped under advisory CERTFR-2026-AVI-1326. Most issues in the batch require local or administrative access, but CVE-2026-0321 stands apart because an unauthenticated attacker with network reach can send crafted traffic to a dataplane interface. Repeated exploitation can trigger a denial-of-service state that pushes the device into maintenance mode. The flaw is rated MEDIUM at 6.6 under CVSS 4.0, reflecting its availability-only impact rather than the ease of exploitation. Analysts recommend handling it on a separate, shorter timeline from the rest of the batch, since its effect is on traffic rather than credentials.

Why PostgreSQL VACUUM Monitoring Matters for Preventing Table Bloat

Table bloat in PostgreSQL can degrade performance for weeks before it is noticed, since symptoms like growing disk usage and slower queries appear indirectly. The cause lies in MVCC, where updates and deletes leave dead row versions that only VACUUM can reclaim, and only once no running transaction still needs them. Autovacuum may be enabled yet still fall behind, because its default trigger thresholds scale poorly on very large tables. Long-running transactions, idle sessions, and replication slots can also hold back cleanup, while cost-limited workers may never catch up on write-heavy tables. Effective monitoring of dead tuples and vacuum activity is therefore needed to catch these problems early.

Only 53 of 1,045 Hours of Sleep Audio Were Usable for Training a Sleep-Phase Model

A developer team recorded about 1,045 hours of overnight bedroom audio to train a sleep-phase model, but only roughly 53 hours met the criteria for training. The main obstacle was not capturing audio, which they described as a solved problem, but obtaining reliable labels that mark sleep stages. Their labels came from wearable devices, which only worked on nights when the phone and wearable recordings overlapped cleanly, and small clock drift or early device failures removed usable hours. They concluded that defining what counts as a valid night, and discarding incomplete recordings, was more important than collecting more data. Their practices included logging each recording's completeness, aligning audio to labels before labelling, and tracking where each label came from.

Tool-cost CI check for MCP servers catches schema growth hidden by token totals

A developer guide describes a reproducible CI check for MCP tool definitions that measures total tokens, descriptions and input schemas separately. It uses an observed remote change to textokit's endpoint, where a 20-tool list lost about 32% of its counted tokens overall, mostly from shorter descriptions. The article provides a full fetch script that verifies canonical digests of the public tool lists before comparing them. Commands use pinned versions of the aimarket-histor CLI and tiktoken, and the author notes this is their own reproducibility check rather than external adoption. The check exits with code 0 when the increase stays within a configured threshold of 10%.
