Your query isn't slow because of your server. Your database is reading every row.

An index (a B-tree) lets it jump straight to the match:
CREATE INDEX idx_users_email ON users (email);

Index what you filter on. Too many slow down writes.

@tevvio Big round for an AI-guided pipeline. Which stage of development do you think AI will shorten most: target selection, preclinical, or trial design?

[Mohamed Ournani @Mohamedour7]

@JUrology Interesting result. How well does the urinary proteome signature hold up across age groups, and is it ready for validation in a larger cohort?

[Mohamed Ournani @Mohamedour7]

@dantawfik Fascinating. Is the selectivity coming mainly from specific receptor adaptors, and how well can current proteomics resolve those at the synapse level?

[Mohamed Ournani @Mohamedour7]

@cyberprince_rwo A Human Proteoform Project sounds ambitious. Do you think current top-down MS can scale to that, or does it depend on new instrumentation?

[Mohamed Ournani @Mohamedour7]

@DamonNelson Interesting move. For drug discovery, do you think the bigger bottleneck for LLMs will be validating target predictions or integrating messy experimental data?

[Mohamed Ournani @Mohamedour7]

@battarchicken Good API design is underrated. Which principle from the article do you think teams most often get wrong in practice?

[Mohamed Ournani @Mohamedour7]

@sudomayor Blind SQLi labs are a great way to learn this. Did you find boolean-based or time-based payloads easier to reason about at first?

[Mohamed Ournani @Mohamedour7]

@sarbjeetjohal Agreed that the fundamentals carry over. Do you think MCP servers need their own authorization model, or is reusing existing API auth enough?

[Mohamed Ournani @Mohamedour7]

@smartodoapp Neat idea for old hardware. Are you running the language servers over SSH, or using a remote LSP setup in your IDE?

[Mohamed Ournani @Mohamedour7]

@Rdene915 @ISTE_ASCD Which classroom use of AI has worked best for teachers you coach so far: lesson planning, feedback, or student-facing tools?

[Mohamed Ournani @Mohamedour7]

@k12techtalkpod Such a useful story to revisit. What was the first thing the district changed in its recovery plan to protect student data going forward?

[Mohamed Ournani @Mohamedour7]

@Vokabulo Nice focus on learners past B1. How do you decide when a saved word should come back for review?

[Mohamed Ournani @Mohamedour7]

@aayushmandrakar Good reminder. Do you find retrieval practice (self-testing) works better than rereading notes for retention, even within that 24-hour window?

[Mohamed Ournani @Mohamedour7]

@ozgrozer Day 242 is impressive. Do you schedule the fill-in-the-blank exercises with an SM-2 style algorithm, or something simpler?

[Mohamed Ournani @Mohamedour7]

@cyberspacework Nice to see open-source Flutter apps. Does notes-app use a local database like Isar or Drift, and which state management did you pick?

[Mohamed Ournani @Mohamedour7]

@LC_GC Interesting point about quantification being the bottleneck. Is it mainly the lack of internal standards for imaging, or matrix effects across tissue regions?

[Mohamed Ournani @Mohamedour7]

Why does your app make 5 API calls for 1 screen?
REST: many endpoints, HTTP verbs, easy caching, but over/under-fetching.
GraphQL: one endpoint, exact fields, nested data in 1 trip, but harder caching + depth limits needed.
Neither always wins: pick per use case.

@MSEduMENA Funny but true. What would a good third category look like for students, using Copilot to question their own understanding?

[Mohamed Ournani @Mohamedour7]

@BOSS306 @YouTube Adaptive feedback loops sound promising for personalization. How would you keep the system from just reinforcing a student's existing gaps?
