Founder of Tweeting about SaaS/tech/bootstra... Who am I kidding, mostly random stuff. Father by day, dev by night.

Jitbit condemns this war. I'm from Russia originally and I'm ashamed of my passport right now. Forgive us Ukraine 🇺🇦 💙💛

@hunvreus Humans too 😃

@IanLandsman Wait, I thought it's taking every SaaS first

top #1 tech story today: Codex finding a way to give itself "sudo" from within the sandbox

top #2 tech story today: all RedHat's NPM packages are compromised

Scary times.

@jessethanley @PlanetScale Wait what... how big is your database?

Ours is 1TB and our entire (!) AWS bill is like $850/mo (standard gp3 EBS'es)

[Alex Yumashev @jitbit]

This is what happens when you rapidly resize AWS web console window.

On a 16 Core M4-MAX MacBook Pro with 64GB ram.

So... yeah.

@CasJam Why not Suno?

[Alex Yumashev @jitbit]

Google: updates SEO guidelines that “llms.txt” and json schemas don’t help with AI dicoverabiltiy at all

Also Google: adds “llms.txt” to Chrome lighthouse checks

which one is it?

[Alex Yumashev @jitbit]

@JordanGal @CasJam @mijustin Jordan, while you're here! That story about your friend vibecoding an app for his construction company!

Oh man... Made me pause my run. Sat on a bench frozen and just digested it for 10 minutes.

The industry is changing. THanks for sharing

[Alex Yumashev @jitbit]

@CasJam huge fan of the panel but one of you guys’ mics needs a highpass, too much lowfreq humming :( + I can here every elbow hittin the table😀

Opus 4.8

[Alex Yumashev @jitbit]

@pmkoom That's Codex, not Claude, Codex does not show memory/meta diffs there 😀

[Alex Yumashev @jitbit]

The biggest challenge with AI is....

...not rage-destroying your effing monitor!!!

[Alex Yumashev @jitbit]

Confirms my observations

[Alex Yumashev @jitbit]

@Shpigford Don't bother.
P.S. Also brace yourself for 100's of comments from directory owners in 3...2....

I can't tell if you're trolling or being serious 😀

Codex Plus is the one for $20.

Includes fewer limits, but they go further than Claude Max because GPT-5.5 uses ~6x fewer tokens to solve the same problem.

I've been kinda testing this for the last 3 months. Have all three subs - Codex/CCode/Cursor - and experimented with the tiers. The verdict is NO, CCode is not "the greatest deal in history" any more.

And now that Composer 2.5 is out, which is effectively unlimited and beats Opus 4.7 on many tasks - CCode is out.

In fact, CCode is the worst software product of the three.

It was first, it showed everyone the way, but there are better options now. There's no reason to use it other than "I'm too used and too lazy to switch".

[Alex Yumashev @jitbit]

Same. And boy the Codex app feels 350% more polished than ClaudeSlop -cough- - sorry- ClaudeCode

[Theo - t3.gg @theo]

It took me like 2 months, but I've grown to love gpt-5.5.

You have to prompt entirely different and put some time into your agents[.]md. Now that I'm over the hump, I can't really use any other model for code.

Nothing makes me happier than dogfooding our own AI and watching it resolve customer's tickets while I'm away

Meanwhile Ferrari

[Alex Yumashev @jitbit]

All the tech youtubers ( @MKBHD , @cleoabram ) reviewing the new Ferrari EV is hilarious.

Now I'll wait for "Scratches at level 6 with deeper grooves at level 7"
