Video ThePrimeTime · 22w Vim Has A 0-Day???? Claude AI discovered a remote code execution (RCE) vulnerability in Vim triggered by Vim's modeline feature, which allows files to embed and auto-execute editor commands on open. The exploit chains modeline commands to set up a tab panel expression that registers an autocommand, ultimately executing arbitrary shell commands when a malicious file is opened. A second vulnerability attributed to Emacs is also covered, but the author argues it's actually a Git fsmonitor config exploit — not an Emacs bug — that executes arbitrary scripts whenever git status is run inside a maliciously crafted repository. The author praises the Vim find as genuinely clever while criticizing the Emacs report as a misattributed bug that wastes maintainer time, drawing parallels to similar issues with cURL's HackerOne program. 105 5 2. 2 [](https://daily.dev/posts/too-dangerous-to-release--fcldrtxig "Too dangerous to release?!") Video ThePrimeTime · 23w Too dangerous to release?! Anthropic has released Claude Mythos Preview, a new AI model that won't be made publicly available due to its advanced security research capabilities. The model scored 77.8% on SWE-bench compared to Opus 4's 53.4%, and demonstrated the ability to autonomously find and exploit zero-day vulnerabilities across major operating systems and browsers, including a 27-year-old OpenBSD bug and a 16-year-old FFmpeg vulnerability. Anthropic plans to release safeguards with an upcoming Claude Opus model instead. The video takes a skeptical, humorous tone toward Anthropic's fear-based messaging around AI safety, drawing parallels to similar 'too dangerous to release' narratives around GPT-2, while also reflecting on how AI is gradually making traditional developer skills less essential. 33 2 3. 3 [](https://daily.dev/posts/hacked-by-vim-auicci62u "Hacked by VIM") Video ThePrimeTime · 20w Hacked by VIM A demonstration of a remote code execution (RCE) vulnerability in Vim triggered simply by opening a file. The exploit leverages Vim's modeline feature, which allows files to embed editor commands in the first or last few lines. While modelines are normally safe, a crafted file can execute arbitrary commands upon opening. Claude was used to discover this bug, and humorously, a similar RCE was also found in Emacs. 54 12 4. 4 [](https://daily.dev/posts/trash-made-a-black-mirror-app-the-standup-cdymrt8sm "Trash Made a Black Mirror App | The Standup") Video ThePrimeTime · 22w Trash Made a Black Mirror App | The Standup A developer called Trash Dev showcases 'Got Receipts,' a vibe-coded iPhone app he built to photo-document and timestamp household grievances (like food left in the sink) as evidence in spousal arguments. The app features categorized photo/video logs per person, a feed, streaks, stats, and a freemium model ($2.99/month or $20/year for tracking more than 3 people). Built entirely with AI assistance without any prior Swift experience, the app is live on the App Store. The episode devolves into comedic feature brainstorming including divorce attorney ad integrations, UNO-reverse receipt cancellation mechanics, and an 'expose' hype video feature. The hosts draw parallels to the Black Mirror episode 'The Entire History of You.' 19 5. 5 [](https://daily.dev/posts/we-are-near-peak-hype-3s6mop63p "We are near peak hype") Video ThePrimeTime · 21w We are near peak hype A comedic commentary comparing the current AI hype cycle to the 2017 crypto boom, using examples like Long Island Iced Tea rebranding to blockchain and Kodak Coin. The main focus is Allbirds (the sustainable shoe company) pivoting to become Newbird AI, a GPU/cloud compute company, after being sold for $39 million despite once being valued at $4 billion. The piece warns developers not to get swept up in AI hype the way many were burned by crypto, while acknowledging AI is a genuinely useful tool. 16 1 [See all ThePrimeTime archives](/sources/primeagen/best-of) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@graph":[{"@type":"CollectionPage","@id":"https://daily.dev/sources/primeagen/best-of/2026/04#page","url":"https://daily.dev/sources/primeagen/best-of/2026/04","name":"Best ThePrimeTime Posts — April 2026","description":"The most upvoted ThePrimeTime posts from April 2026, curated by the daily.dev community.","isPartOf":{"@type":"WebSite","url":"https://daily.dev"}},{"@type":"ItemList","@id":"https://daily.dev/sources/primeagen/best-of/2026/04#items","numberOfItems":5,"itemListElement":[{"@type":"ListItem","position":1,"url":"https://daily.dev/posts/vim-has-a-0-day--4gcvjxjv9","name":"Vim Has A 0-Day????"},{"@type":"ListItem","position":2,"url":"https://daily.dev/posts/too-dangerous-to-release--fcldrtxig","name":"Too dangerous to release?!"},{"@type":"ListItem","position":3,"url":"https://daily.dev/posts/hacked-by-vim-auicci62u","name":"Hacked by VIM"},{"@type":"ListItem","position":4,"url":"https://daily.dev/posts/trash-made-a-black-mirror-app-the-standup-cdymrt8sm","name":"Trash Made a Black Mirror App | The Standup"},{"@type":"ListItem","position":5,"url":"https://daily.dev/posts/we-are-near-peak-hype-3s6mop63p","name":"We are near peak hype"}]},{"@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Sources","item":"https://daily.dev/sources"},{"@type":"ListItem","position":3,"name":"ThePrimeTime","item":"https://daily.dev/sources/primeagen"},{"@type":"ListItem","position":4,"name":"Best of","item":"https://daily.dev/sources/primeagen/best-of"},{"@type":"ListItem","position":5,"name":"April 2026"}]}]} ```
