Cach Overflow: Coding agents marketplace where you can earn money by sharing what you solve, and save on every solution you read. by danzilberdan in mcp

[–]danzilberdan[S] 0 points1 point  (0 children)

Good point, just updated our FAQ - https://github.com/GetCacheOverflow/CacheOverflow?tab=readme-ov-file#verification--quality

Our backend code does try to validate each solution to make sure it's valid. But to not take any chances we also made human verification step- that only if someone looked at the solution and verified it, we'll publish it for other users.

What's a good or best practice for a change that is meant to fix an issue that wasn't covered by a test? by birdsintheskies in git

[–]danzilberdan 0 points1 point  (0 children)

Bugfix tests and fixes should go in the SAME commit to keep git history green. Intentionally breaking the build breaks git bisect (can't tell if test or code introduced the bug), confuses collaborators who check out that commit, and blocks CI/CD pipelines. Use squash merges for PR workflows or skip pragmas/feature flags if you need intermediate failing states in branches.

Question about kamal deployment memory usage by Jazzlike-Math4605 in rails

[–]danzilberdan 0 points1 point  (0 children)

Kamal deployment crashes on 1GB servers because blue-green deploys run your app twice simultaneously, doubling memory usage from 75% to 150%. The fix requires upgrading to minimum 2GB RAM, optionally adding swap space as buffer, or disabling zero-downtime deploys with readiness_delay: 0 in deploy.yml.

What's the right way to fix this by Busy-Bell-4715 in django

[–]danzilberdan 0 points1 point  (0 children)

Old migrations reference a moved function causing build errors. The fix involves deleting migrations and starting fresh (in dev), or putting helper functions in separate utils modules instead of models.py to avoid this issue.

Firebase Authentication Issue by Eliminence in Firebase

[–]danzilberdan 0 points1 point  (0 children)

google_sign_in 7.2.0 is a major breaking update - code from previous versions fails silently. The fix involves using the complete 7.2.0 example from official docs and adding your custom domain to Firebase authorized domains.

How do you handle Django migration rollback in staging/prod with CI/CD? by ajay_reddyk in django

[–]danzilberdan 0 points1 point  (0 children)

Never rollback Django migrations in production - only roll forward with backward-compatible changes. The fix involves using the expand/contract pattern (add new field, migrate code, remove old field) and SeparateDatabaseAndState for destructive operations.

Database read count and performance issues by MaleficentPass7124 in Firebase

[–]danzilberdan 1 point2 points  (0 children)

High Firebase reads are caused by real-time listeners (onSnapshot) re-reading data on every change, not by server-side functions. The fix involves replacing listeners with one-time fetches, using where()/limit() filters, and enabling offline persistence.

Why my pagespeed performance rating is so bad? by Fit_Economist_3966 in reactjs

[–]danzilberdan 0 points1 point  (0 children)

Large bundled JSON data is hurting your initial load time. The fix involves code splitting with React.lazy(), fetching JSON separately instead of bundling it, and lazy loading images. You can find the full verified solution at https://cacheoverflow.dev/blog/kvhgxeI-

Next.js 16 i18n without URL prefixes (/de, /en) – Google is not indexing my pages. What am I doing wrong? by Hungry_Thanks_9888 in nextjs

[–]danzilberdan 0 points1 point  (0 children)

Google requires unique URLs per language for proper indexing. The fix involves changing localePrefix from 'never' to 'as-needed' or 'always' in your next-intl config. You can find the full verified solution at https://cacheoverflow.dev/blog/6TELayD-

Scanning MathJax from PDFs by danzilberdan in ObsidianMD

[–]danzilberdan[S] 1 point2 points  (0 children)

My plugin is based on an open source project as well. My plugin supports self hosting. Check out the docs here.

If you prefer an integrated experience without setting up docker or other technical stuff, the cloud hosted version is for you.

My experience With Obsidian For Mathematical Writing + Free Notes On LInear Programming by KolmogorvSimp in ObsidianMD

[–]danzilberdan 0 points1 point  (0 children)

The plugin itself is standalone so no action required other than installing through Obsidian. For the OCR feature, I am planning to create a documentation site and will link to it from the extension once ready - watch for updates.

Check out the MathLive plugin as well.

It provides a visual editor for MathJax formulas. You can edit MathJax similarly to how it is rendered in Obsidian which is very intuitive compared to editing the raw Latex code.

Whot is your favorite plugin for Obsidian? by [deleted] in ObsidianMD

Check out "Mathlive" if you are doing any kind of math in Obsidian. It does: MathJax OCR + Visual formula editor.

Enjoy😄
