Your git log knows the hour you really code. One line prints it.

Vibeoverflow — Thu, 22 Oct 2026 09:26:21 +0000

The legend says real hackers commit at 3 AM. Your git history can check that, and it takes one line.

git log --author="$(git config user.email)" --date=format:%H --format=%ad |
  sort | uniq -c |
  awk '{c[$2]=$1; if ($1>m) m=$1}
       END {for (h=0; h<24; h++) {k=sprintf("%02d",h); b="";
            for (i=0; i<c[k]*30/m; i++) b=b "#"; printf "%s %5d %s\n", k, c[k], b}}'

Run it inside any repo. It prints 24 rows, one per hour, with the number of your commits at that hour and a bar.

The creator of Redis codes in office hours

I ran it on Redis with --author=antirez: 7,213 commits from 2009 to today.

His peak is 11 AM. There is a dip at 2 PM, the hour after lunch, and a second peak at 4 PM. Between 3 and 6 AM he made 54 commits in 17 years. One of the most-used databases on earth was written mostly between breakfast and dinner.

How it works

--date=format:%H prints only the hour of each commit, in the author's own time zone at the moment of the commit. A commit at 2 AM in Tokyo counts as 2 AM.
sort | uniq -c counts the commits per hour.
awk fills in the hours with no commits and scales the longest bar to 30 characters.
Your email in old commits may differ from the one in your config. Use --author="Your Name" then; it matches part of the name or the email.
For every repo in a folder, wrap the git log in a loop: for d in ~/code/*/; do git -C "$d" log ...; done, then pipe the whole loop into the same sort | uniq -c | awk.

Then the other half: your last 30 days

The hours come from your machine. Your days are public: the green squares on your GitHub profile. We made a monkey, Jitters, who lives those 30 days. Type your handle at vibeoverflow.lol and he shows the month you had: on the sofa after a quiet week, on his toes during a streak, shaking on his eighth coffee if you push ten times a day.

Your peak hour can also go on a mug, under him: the same page takes the hour you type and puts it on the mug in the cart.

What is your peak hour? Post your bars below. Does anyone here really peak at 3 AM?

Gifts for the vibe coder whose AI writes the code at 3am (2026)

Vibeoverflow — Thu, 22 Oct 2026 00:54:01 +0000

Some links below pay us a small commission if you buy (Zazzle's referral program). The products are other people's except one, which is ours and says so. Prices are as each shop showed them on 22 October 2026, in USD unless marked; Zazzle runs sales often, so yours may differ.

Somebody you love now writes code by talking to it. They describe a thing, an AI types it, they read the diff at 3am and say "looks right", and then it is 4am. You want to get them a gift, and every programmer gift guide since 2012 says split keyboard, rubber duck, mug warmer.

This list is for the other kind. One gift for each hour of a night spent asking a machine to write the code, from the last good idea to the sunrise. Every link was opened before it went in.

10. Jitters at your hour, personalized mug (ours, Vibeoverflow) - from our shop.
A small anxious monkey who codes, on a mug that prints the hour you choose: the time they usually give up, or the time they shipped the thing. We make him, so we would say this; the hour is the part that makes it theirs.
See the mug and the stickers

11. Vibe Coding: Building Production-Grade Software With GenAI, Chat, Agents, and Beyond by Gene Kim and Steve Yegge (Barnes & Noble) - $32.00 paperback.

We turned GitHub contribution graphs into a monkey for your README

Vibeoverflow — Wed, 21 Oct 2026 13:38:24 +0000

Stats cards tell you numbers. We wanted one that tells you how your month felt.

So we made Jitters: a monkey who lives your last 30 days of public GitHub contributions. One line in your profile README and he sits there, redrawn once a day.

The rules, first one that holds wins:

Seven days with nothing pushed: he is on the sofa.
Ten or more a day for 30 days: he shakes, coffee after coffee.
A streak of seven days or more: he stands on his toes.
One or more a day: he types along.
Less than one a day: he dozes at the desk.

Today @dhh's monkey is on his eighth coffee (112 contributions a day), @antirez's types along, and @karpathy's is on the sofa: his public calendar has been quiet for 30 days.

Put yours on your README

Replace YOUR_HANDLE with your GitHub handle:

[![Jitters](https://vibeoverflow.lol/card/YOUR_HANDLE.svg)](https://vibeoverflow.lol/scenes/github.html?h=YOUR_HANDLE&src=readme)

Or type your handle at vibeoverflow.lol/scenes/github.html and press copy.

How it works

It reads the public contribution calendar, the same green squares on your profile, once a day per handle. No token, no login, nothing private.
The card is one self-contained SVG, 480 by 160: no font or image loaded from outside, because GitHub's image proxy fetches only the one URL.
It answers Cache-Control: no-cache with an ETag, so the proxy asks again instead of keeping last week's monkey.
A handle that does not exist gets a sleeping monkey, never a broken image.

What is your monkey doing this month?
