No longer can find Apple keynote on App Store for some reason.
Can only find it from my purchase history.

Firestore trick that will make your Firebase app feel as fast as a local app:
Turn on persistentLocalCache, then on every page load fire two reads at once:
1. getDocsFromCache → paint instantly
2. getDocs → swap in fresh data
Now every navigation is instant.
did they spend all their money on ads so they can be 7x24 on my feed?
We just raised $5.7M for @PolarBrowser, the AI browser that beats Anthropic and OpenAI on every major web agent benchmark.
- 4,500,000+ actions taken for users, automating sales, recruiting, and ops
- One company cancelled Clay and saves 25+ hrs/wk per person
- Team is from MIT, YC, Prod, Citadel, Jane Street, Perplexity, Modal, and Apple
100 hours of work. From 30 seconds of typing.
Download the world's most powerful AI browser: polarbrowser.com
The last three mins of this review tho: youtu.be/o1qc29t04GI?is=kZY1…
HTX’s conclusion is spot on.
Maybe the ideal fold is the classic fold with one screen.
Not only am I no longer feeling guilty of not touching my codex credits, I also can’t seem to get my $100 Claude sub to over 80% usage every week, my energy and attention is the constraint, Anthropic and OAI needs to find more intensive ways to spend our tokens by introducing audio video models or something… or build better harness. I’m sure this is what having a 20G hard disk feels like in the year of 2000… and I’m sure they will succeed. But if they do spend one minute figuring it out I’m sure the market will be like: “the AI bubble is bursting”…
In the meantime, regular people who are not exposed to AI and only AI hate were like: does it consume astronomical number of water? Why do you keep producing AI slop?
Is this Anthropic’s first real stab at consumer market? OAI will be in danger if they can pull this off. Now their less polished Claude code app will become an advantage so they can split the attention and efforts with a dedicated app. They will be unstoppable when they wait OpenAI to release their opus 5.5 equivalent mode and follow up with fable 5.5…
The owner of Outlook, Microsoft, can’t compete with SES and has to shutdown their only viable email provider service on azure just few years after GA.
Of course, the owner of Gmail, the most popular email provider, didn’t even bother trying.
learn.microsoft.com/en-us/az…
All these recommended cloudflare, have your agent ever read about their terms? It says no marketing and promotional emails.
developers.cloudflare.com/em…
Also I got SES sorted out in half a hour and exit sandbox approved in mins with $100 AWS credits on top. I’m amazed no one else among the azure and GCS has figured this out yet.
I’ve wanted to build my own LMS for more than a decade. I followed and admired CanvasLMS when it was first open sourced, taught online with it as an FFT user (university was still on moodle), then spent over ten years in edtech. I’m outside academia now, and honestly a bit out of touch, but for the first time it feels like we can actually build it (it's an order of magnitude less complex than Photoshop right?).
This is a first take: minimalist and text-first. Nothing real is built yet. It’s a clickable design with made-up data.
It’s also just one dimension. I have a handful of other variations (range from promising to insane) I want to explore too.
So before I indulge myself too much: should this exist? What would make you use it, or keep you away?
Watch the 2-minute video and let me know.
Or click through the demo: zenlms.idealistspace.com
This analytics tool checks all my boxes, anyone else using traks? traks.dev/
When you control your own email infra, you can just dream up random crazy features in the morning and have it ready by 10am.
The social media should have a temp mute button for any topic. I’ve watched the roadster demo, it’s COOL, now can I mute everyone’s comments on how cool it is?
Just spent the afternoon switching from cloudflare email sending (which doesn’t support marketing emails) and resend (which has a subscription for pay to go) to SES with a custom CRM/newsletter app, that support multiple domains and products. So much nicer than Kit, it even has a linear-like local first sync engine…with all states in a local SQLite, everything feels so fast.
just signed up for SES, production application was approved in mins, now I can send 50k emails per day... 😂 but i agree without an agent, this is going to a nightmare to click thru, AWS still has the worst console UI across all providers, maybe cos it's enterprise ready and has too many controls
Long compelling list but not many use all the features of MS Office suite and everyone has their own unique list that’s just a handful. These are mine:
- custom product events that auto tag contacts
- receiving emails from customer replies
- multiple workspaces support
- per contact email timeline with notes
- auto AI generated draft using the timeline context
That’s why I’m on my internal system. Deliverability is not a huge problem if you are just the single trusted tenant not trying to spam anyone. I’m not even sharing or selling it as there is no reason to.
every week someone tells me they’re going to vibe-code their own @beehiiv alternative over the weekend.
wishing them the best, here’s the backlog of things to make sure to include:
> 99.3% email delivery rate (industry-leading)
> team of deliverability experts with decades of experience
> infrastructure to send 3M+ emails per minute
> validating every single email submission (1st and 3rd party)
> automated bot-detection to prevent spam signups
> registering for every mailbox provider’s feedback program
> ingesting data from said feedback loops and building suppression lists
> tagging every email so gmail reports complaint rates per newsletter
> classifying every bounce (hard, soft, mailbox full, DNS failure) and knowing which ones mean “try again” vs. “never again”
> three layers of suppression: global, per-publication, and transactional
> temporary suppressions that expire on their own, and permanent ones that never do
> one-click unsubscribe, the way gmail and yahoo now require it
> warming new IPs and domains on a schedule
> watching blocklists around the clock, and pulling an IP from rotation the moment it’s listed
> retrying deferred mail for 24+ hours before calling it a bounce
> blocking disposable, invalid, and typo’d addresses before they ever reach the list
> rate limiting every signup endpoint a bot can find
> filtering bot clicks out of every report (something we pay an ungodly amount of money for)
> an acquisition source on every subscriber
> engagement history for every reader, across every post
> multiple sender addresses for different emails
> custom domain configuration that is aligned with DKIM, SPF, DMARC
> a true WYSIWYG editor: what you write is what lands in the inbox, with no HTML required
> turning that editor into table-based, inline-styled email HTML that holds up in outlook
> real-time collaborative editing, so the whole team can work on the same issue at once
> dynamic content: different sections for different readers, all in a single send
> separate email and web versions of every post, from one draft
> free and premium versions of the same post, split by a paywall break
> merge tags that personalize every email, and a simulated subscriber to preview them before you send
> templates with saved colors, fonts, and spacing, plus a default style for every post
> columns, tables, buttons, blockquotes, sections, file attachments, and a table of contents with anchor links
> native embeds for X, youtube, tiktok, instagram, bluesky, stocktwits, and podcast episodes
> polls, referral blocks, recommendations, and ad slots, built right into the post
> an AI writer, AI images, and a built-in AI agent one keyboard shortcut away
> images resized and optimized automatically, however they’re uploaded
> a live email-size gauge that warns you before gmail clips your newsletter
> custom HTML blocks, cleaned so a stray script tag can’t break your post
> automatically hiding anything an inbox can’t handle (video, iframes, audio) in the email version, while keeping it on the web
> links and embeds made clickable even in outlook, which ignores links wrapped around tables
> vertical alignment in columns, because a layout that looks off by 4px looks broken to readers
> converting your newsletter to audio versions for readers who prefer to listen
> random cohort sends to randomly split your list to test different content and conversion
> slash commands: type “/” and insert any block without touching a menu
> markdown and keyboard shortcuts for people who never want to touch a mouse
> pasting from google docs with the formatting intact
> search and replace across the whole post
> comment threads right in the draft, so editors and writers stop living in google docs
> footnotes and citations that work in the inbox and on the web
> code blocks, for the technical newsletters
> an AI writer that rewrites, translates, and fixes spelling and grammar in place
> autosave, so a closed tab never costs you a draft
> subject line A/B testing, built into the send flow
> drag-and-drop images, from your computer, your media library, or a URL
> rich-text image captions, plus image titles and alt text for accessibility

oh, and besides having to manage all of this on your own indefinitely forever… your vibe-coded solution will still require paying for and stitching together a ton of software:
> email sending (sendgrid, amazon SES, postmark)
> web hosting (vercel, AWS, render)
> database + queue (supabase, neon, RDS)
> payments (stripe, memberful)
> auth (clerk, auth0, supabase auth)
> monitoring + alerting (sentry, datadog, pagerduty)
> workflow engine (inngest, temporal, upstash qstash)
> bot protection (cloudflare)
> email validation (zerobounce, kickbox)
> email rendering (litmus, email on acid)
> click verification (omnivery)
> media storage + CDN (S3, R2, vercel blob)
> product analytics (posthog, mixpanel)
…but at least you saved $59/mo not paying for @beehiiv anymore 🫡
