• Need a per-repo…

  When you build tooling around git repos, you eventually hit "where do I store a per-repo setting?" Committing a .toolrc pollutes the repo and needs a PR; a sidecar file in ~/.config can't easily be per-repo. The clean answer: put it straight into git config under your own namespace. # per-repo (lands in <repo>/.git/config — local, never committed) git config --local mux.adhocWorktree false # per-machine, all repos (lands in ~/.gitconfig) git config --global mux.adhocWorktree false # read it back, normalized to true/false git config --bool --get mux.adhocWorktree # -> false ; exit 1 if unset git lets you invent any <section>.<key> it doesn't recognize (mux.* here) and just stores it. That hands you three things for free that you'd otherwise have to build: A per-repo store that never leaks — .git/config is local to the checkout and never committed, so it won't pollute someone else's repo. Scope layering with native precedence — --local (repo) transparently…

• PI_CODING_AGENT_DIR…

  If you copy pi's default config to a custom dir and it silently "doesn't work at all" (no auth, no models), you probably pointed PI_CODING_AGENT_DIR one level too high. The trap is that pi's default and its env override are asymmetric: Default (no env var): the agent dir is ~/.pi/agent. Your auth.json/models.json live in ~/.pi/agent/. Override: PI_CODING_AGENT_DIR is used verbatim as the agent dir — no /agent is appended. So this looks right but isn't: # WRONG: pi reads ~/.piz/auth.json (empty) and ~/.piz/models.json (missing) PI_CODING_AGENT_DIR=~/.piz pi # even though your real config is in ~/.piz/agent/ The fix is to point the variable at the agent leaf, mirroring the default layout: PI_CODING_AGENT_DIR=~/.piz/agent pi The relevant resolution (packages/coding-agent/src/config.ts): export function getAgentDir(): string { const envDir = process.env[ENV_AGENT_DIR]; if (envDir) return expandTildePath(envDir); // used as-is return join(homedir(), CONFIG_DIR_NAME,…

• For a rotating…

  If you put Pi behind a local Anthropic gateway that rotates multiple Claude accounts, the interesting part is not the token format. The gateway may hand Pi a placeholder token like claude, while the real upstream auth happens inside the proxy. That means request shaping should be attached to the anthropic provider itself, not gated on whether the token looks like sk-ant-oat.... In pi-anthropic-auth, the fix was to make the transport wrapper unconditional for Anthropic requests. Pi already routes the built-in anthropic provider through the same registry transport, so once the request is in that lane, it can be shaped every time: pi.registerProvider("anthropic", { oauth: anthropicOAuthOverride, api: "anthropic-messages", streamSimple: createAnthropicOAuthStreamSimple(builtinTransport.streamSimple), }); That lets the proxy stay dumb and flexible. I ended up using ~/.pi/agent/models.json to point anthropic.baseUrl at the local gateway, and a placeholder OAuth record in…

• Got personal files…

  When you want Git to ignore something that's yours — a local scratch dir, editor cruft, a personal plans/ folder, machine-local config — don't add it to the tracked .gitignore. That file is shared: a rule like plans/ or wiki-drafts/ forces your personal directory conventions onto everyone, and they don't have those dirs. Put it in .git/info/exclude instead. Same syntax as .gitignore, but it's per-clone and never committed — so it's invisible to teammates and travels with nothing: # .git/info/exclude .claude/settings.local.json .claude/plans/ .claude/wiki-drafts/ The rule of thumb: **.gitignore is for what the project should ignore (build output, node_modules/, *.user); .git/info/exclude is for what you happen to ignore on this machine.** If a teammate cloning fresh wouldn't also produce the file, it doesn't belong in the shared list. One gotcha with worktrees: info/exclude lives in the common git dir, so it's shared across all linked worktrees of the same clone — but still not across…

• Shell scripts can't…

  A shell script always runs in a subshell. Any cd it executes vanishes when the script exits — the calling shell's working directory is unchanged. The fix: source the script instead of executing it. Sourcing runs the script in the current shell, so cd sticks. alias sw='. ~/bin/sw' Two things to update in the script itself. First, replace every exit with return. exit in a sourced script exits the entire shell, not just the script: exit 1 → return 1 Second, $0 in a sourced script is the shell binary (bash), not the script path. Use ${BASH_SOURCE[0]} wherever you need the script's own location: source "$(dirname "${BASH_SOURCE[0]}")/git-common.sh" script_name=$(basename "${BASH_SOURCE[0]}") The one tradeoff: functions defined inside the script leak into the shell's namespace after it returns. For a personal utility this is usually fine.

• Keep secrets out of…

  When you give an AI coding agent access to your workspace, any .env file in the project is fair game. The agent will read it, and the secrets end up in conversation history, logs, or tool call outputs. The fix isn't stricter prompting — it's structural: don't put the secrets there at all. credential-gateway is a local proxy that solves this by injecting credentials at the network level. Your application connects to localhost:8080 (or localhost:3307 for MySQL, localhost:6380 for Redis) with no credentials in the connection string. The gateway holds the real credentials in ~/.config/credential-gateway/config.yaml — outside every project worktree — and injects them before forwarding each request upstream. The config file lives at ~/.config/credential-gateway/config.yaml (or /etc/credential-gateway/config.yaml). The gateway refuses to start if the file is group- or world-readable, so a forgotten chmod doesn't quietly undo the whole point. # example: OpenAI-compatible HTTP proxy proxies: -…

• Stuck mid-task…

  If you use Claude Code heavily, you've probably hit the quota wall mid-conversation and had to either wait or manually switch to a second account — digging up the right ANTHROPIC_AUTH_TOKEN, setting the env var, restarting. It's enough friction to break flow completely. agent-quota-gateway is a small Go reverse proxy you run locally on 127.0.0.1. You configure your Claude Code client to point at it instead of api.anthropic.com, and it manages a pool of your accounts behind the scenes. When one hits its quota limit, the gateway automatically switches to the next one and tells the client to retry — the mid-task context survives, the switch is transparent. # point Claude Code at the local gateway export ANTHROPIC_BASE_URL=http://127.0.0.1:9099 # the gateway reads credentials from env vars at startup AQG_POOL_MAIN_BACKEND_ACCT1=sk-ant-... AQG_POOL_MAIN_BACKEND_ACCT2=sk-ant-... A nice side effect: because the gateway does credential substitution on every request, your real OAuth tokens…

• LightDM login…

  When earlyoom kills dbus-daemon under memory pressure, the user's systemd instance ([email protected]) enters a broken state: all user-level sockets fail with status=219/CGROUP because the cgroup delegation context is corrupt. The next login attempt connects to /run/user/1000/bus — the socket file is still there — but nothing is listening, so dbus-update-activation-environment gets "Connection refused" and xfce4-session (or any DE) crashes immediately. LightDM sees the session exit and returns to the greeter. The fix-display script (stop lightdm, kill stray X locks, restart lightdm) doesn't help here because the problem isn't an X lock — it's a dead D-Bus. Diagnosis cat ~/.xsession-errors # dbus-update-activation-environment: error: unable to connect to D-Bus: # Failed to connect to socket /run/user/1000/bus: Connection refused # /usr/bin/x-session-manager: X server already running on display :0 sudo -u davidw XDG_RUNTIME_DIR=/run/user/1000 systemctl --user list-units…

• Native TUI hangs in…

  Launching a native Windows console TUI (Claude Code, codex, etc.) from a tmux pane on Git Bash gives you a frozen screen with a blinking cursor. The usual advice is "wrap it in winpty" — that's wrong, and it took three layers to get to the real fix. winpty cannot bridge through tmux winpty <app> works fine in plain mintty, so it's tempting. But inside a tmux pane it deadlocks: as the pane's initial command it hangs forever; as a child of the pane shell it exits with stdin is not a tty. winpty needs to own a Windows console and bridge stdio, and tmux's pty layer breaks that bridge. Don't reach for it in tmux. The console comes from ConPTY, which disable_pcon kills Native Windows apps can't use an MSYS/Cygwin pty as a console — to them it's just a pipe, so isatty() is false and the TUI renders garbled or bails. Modern MSYS solves this with ConPTY backing, controlled by the MSYS env var. Check yours: echo "$MSYS" # winsymlinks:nativestrict disable_pcon <- the…

• Tired of Jira's…

  If your day looks like open Jira → wait for the SPA to boot → hunt for the ticket → click into the status dropdown → wait again, you already know the tax. Most of what we actually do to a ticket — move it, comment on it, assign it — is two seconds of intent buried under ten seconds of web app. jira-sh is a tiny bash CLI that skips all of it. One command, jr, talking straight to the Jira Cloud REST API. jr move PROJ-123 "In Review" jr comment PROJ-123 "Deployed to staging" jr view PROJ-123 No Electron, no browser, no waiting. It's a single bash script plus curl and python3 (standard library only for the core commands).

• IT blocked SSH to…

  If a network policy change suddenly breaks git push/pull to [email protected]:..., the panic response is for r in */; do git -C "$r" remote set-url origin ...; done across N repos. Don't. Add this to ~/.gitconfig and never think about it again: [url "https://github.com/"] insteadOf = [email protected]: What it does: any URL starting with [email protected]: is transparently rewritten to https://github.com/... at fetch/push time. git remote -v still shows the SSH form (good for humans), but the actual network request goes over HTTPS (good for the firewall). Verify it works without pushing anything: GIT_TRACE=1 git ls-remote [email protected]:YOUR_USER/YOUR_REPO.git Look for run_command: ... remote-https ... in the output. If you see remote-ssh, the rule isn't matching (typo, wrong section, or a system-level gitconfig overriding it). The rule also covers submodule URLs and any URL that happens to embed [email protected]: — they're all rewritten the same way. If you have other GitHub…

• Two GitHub accounts…

  If you run gh auth setup-git, the GitHub CLI becomes git's credential helper — and it only ever hands out the token for the active account. The moment you git pull a repo belonging to your other account, you get the wrong token (403, or commits land under the wrong identity). There's no per-repo routing; you'd have to gh auth switch every single time you cross accounts. You can prove it to yourself — ask the helper for the non-active account and it returns nothing: "protocol=https`nhost=github.com`nusername=second-account`n`n" | & gh auth git-credential get # exit 1, no token The fix is to hand git over to Git Credential Manager (it already ships with Git for Windows). GCM picks the token by the username embedded in the remote URL, so routing becomes automatic. gh keeps working for gh issue/gh pr — it uses its own keyring, separate from the git helper. Switch the helper and point GCM at GitHub: git config --global --unset-all credential.https://github.com.helper git…

• tmux Alt+z for pane…

  tmux's built-in pane zoom (Prefix+z) can be unreliable for users with Chinese input methods. The standalone z keystroke may be intercepted by the IME before tmux sees it, forcing you to switch to English mode first. Bind Alt+z as a prefix-free shortcut instead: bind -n M-z resize-pane -Z M-z (Alt+z) is sent as a Meta key sequence directly to the terminal, which most input methods don't intercept. The same logic applies to navigation—add hjkl pane switching without the prefix: bind -n M-h select-pane -L bind -n M-j select-pane -D bind -n M-k select-pane -U bind -n M-l select-pane -R This keeps tmus responsive regardless of your current input state.

• Show each tmux…

  When you split a window into several panes — say a dev/planner/reviewer layout — it's easy to lose track of which directory each one is actually in. tmux exposes pane_current_path, so you can paint the cwd right onto the pane's top border: set -g pane-border-status top set -g pane-border-format " #{pane_index}: #{pane_title} [#{pane_current_path}] " Full paths get long and crowd out the title. Two ways to trim. #{b:...} gives just the basename (last component): set -g pane-border-format " #{pane_index}: #{pane_title} [#{b:pane_current_path}] " Or abbreviate $HOME to ~ with tmux's s/search/replace/ modifier. The neat trick is that the replacement is itself a format, so you can nest #{HOME} inside it — no hardcoded username, so the same dotfile works on every machine: set -g pane-border-format " #{pane_index}: #{pane_title} [#{s|^#{HOME}|~|:pane_current_path}] " s takes any delimiter after it; using | keeps the slashes in the path readable, and ^ anchors…

• tmux `run-shell`…

  A common pattern for "hop to another session before killing this one" looks like this: bind Q run-shell 'next=$(tmux list-sessions -F "#{session_name}" 2>/dev/null \ | grep -v "^#{session_name}$" | head -1); \ if [ -n "$next" ]; then tmux switch-client -t "$next"; \ tmux kill-session -t "#{session_name}"; \ else tmux kill-session; fi' It doesn't work. run-shell expands all #{...} format strings before handing the command to the shell. So list-sessions -F "#{session_name}" becomes list-sessions -F "mysession" — a literal string, not a format specifier. Every session prints "mysession", grep -v strips them all, $next is always empty, and you drop straight to bash. The fix is one line: set -g detach-on-destroy off bind Q kill-session detach-on-destroy off is a native tmux option: when a session is destroyed, the client automatically switches to another surviving session. It only falls back to…

• tmux: Hold Alt and…

  The standard way to switch to the previous tmux session is prefix + ( (or a custom prefix + b). The problem: every switch requires the full prefix chord again. You can't hold Ctrl and keep tapping — tmux swallows the first keypress as the prefix and expects a fresh command key each time. Use a no-prefix binding instead. Add to ~/.tmux.conf: # Alt+b to switch to previous session (no prefix needed). bind -n M-b switch-client -p The -n flag means "no prefix required." Now you hold Alt and tap b repeatedly to cycle through sessions — no prefix dance, no finger gymnastics. Why Alt+B and not something else: it's close to the default prefix (Ctrl+B) so it's easy to remember, and it doesn't conflict with any common terminal or shell binding. Your mileage may vary if you use Alt-heavy terminal apps.

• Launch a new tmux…

  Tools like team and adhoc (from the mux-relay framework) derive the project root from $PWD at invocation time. The natural instinct is to open a new tmux window, cd to the target directory, then run the command. That works, but it leaves a ghost window in the original session — and if that window gets cleaned up or the session reshuffles, pane working directories can silently drift to deleted paths. A subshell avoids all of that: (j my-project && team) The parentheses spawn a subshell. Inside it, j (zoxide) changes directory to the project, then team launches the new session with the correct $PWD. Because new-session -d is detached and switch-client handles the jump, the new session is fully independent — no nesting, no leftover windows. When the subshell exits (right after team returns), the original pane's $PWD is untouched. You never left it. This pattern works for any command that reads $PWD but doesn't accept a -C / --directory flag: (cd ~/Projects/something &&…

• diffstat: the first…

  When you're staring at a 5000-line diff, your eyes glaze over before you've read past the first file. diffstat gives you the bird's-eye view in one screen: gh pr diff 137 | diffstat lib/relay-runtime.sh | 2692 ----------------------------------- lib/relay/backends.sh | 142 ++++ lib/relay/cli.sh | 326 +++++++ lib/relay/cycle.sh | 99 ++ lib/relay/issue-comments..| 179 ++++++ lib/relay/issues.sh | 173 ++++++ lib/relay/project-regist..| 274 ++++++++ lib/relay/session.sh | 692 ++++++++++++++++++++++++++ lib/relay/telegram.sh | 389 ++++++++++++++++ lib/relay/tmux-send.sh | 337 +++++++++++++++ lib/relay/worktree.sh | 206 ++++++++ 11 files changed, 2848 insertions(+), 2686 deletions(-) From that one output you can immediately see: this is a file split (one huge file → ten smaller ones), the net change is roughly neutral, and session.sh is the biggest new file at 692 lines.

• When your…

  The my-ai-team relay has a .my-ai-team/<mode>.md prompt override mechanism — drop a markdown file into a directory and it replaces the shipped system prompt for that agent mode. It never worked in practice. The code was there, the tests passed, but real users' override files were never found. The bug was a root resolution mismatch, not a logic error. The mechanism _mux_prompt_override() in lib/relay-runtime.sh decides which prompt file an agent gets: relay_root="$(_mux_relay_root)" override_path="${relay_root}/.my-ai-team/${mode}.md" It looks for .my-ai-team/<mode>.md under the relay root, then falls back to agents/<mode>.md. What went wrong _mux_relay_root() returns the install root (~/.local/share/my-ai-team/), not the project root. Meanwhile mux-agent-launch correctly receives MUX_PROJECT_ROOT (the user's project directory) and even cds into it — but _mux_prompt_override() never sees it. Users put .my-ai-team/ in their project.

• "Permission denied"…

  You try to rename a directory and get blocked: # Git Bash $ mv my-ai-team my-ai-team.old.1 mv: cannot move 'my-ai-team' to 'my-ai-team.old.1': Permission denied # PowerShell, even elevated PS> Move-Item .\my-ai-team .\my-ai-team.old.1 Move-Item: You do not have sufficient access rights to perform this operation or the item is hidden, system, or read only. The instinct is to reach for chown/takeown/icacls. On Windows that's usually the wrong tree to bark up. When even an administrator shell is denied, the cause is almost never the ACL — it's a runtime lock: some process has a file inside the directory open, or has the directory itself as its current working directory. Windows surfaces that lock as "Access denied," which reads like a permissions problem but isn't. Rule out permissions in two commands …more

• Turn off Tailscale…

  If you enabled Tailscale's built-in SSH server with tailscale up --ssh and then realized you'd rather just use OpenSSH with a real key (no periodic browser auth to Tailscale, fewer moving parts), the way you turn it off matters. Use this: sudo tailscale set --ssh=false It flips that one flag and nothing else. tailscale status stops listing the SSH service, OpenSSH is untouched, your existing tailnet connection keeps running. The trap is reaching for tailscale up --ssh=false. up is sticky — it reapplies your full login configuration — so it can prod you to re-authenticate in the browser, and any other flags you tweaked but forgot about get reset to defaults too. set is the surgical knob for toggling a single option without disturbing the rest. Same shape applies to other booleans Tailscale exposes (--advertise-exit-node, --accept-routes, --shields-up): once the node is up and authenticated, prefer tailscale set --flag=... over re-running tailscale up.

• Designing "Explore"…

  I run a small multi-agent dev setup (my-ai-team) with three session modes: team (planner/developer/reviewer relay), adhoc (one agent owns the whole delivery cycle), and explore. The explore mode is still an RFC — we haven't shipped it yet. But the design already taught us something useful about how to scope agent autonomy. The first draft was all negatives The obvious way to define an investigation-only mode is to list what it can't do: no issues, no branches, no PRs, report findings and stop. That works — until it doesn't. The problem: there's always a case the fence didn't anticipate. If poking at a bug turns up a one-line fix, the rules force an awkward choice between "break protocol and just fix it" or "hand off to a separate session for a trivial change." Neither is right. Define by entry condition instead The fix was to redefine explore by how it starts, not what it's forbidden from doing. Team and adhoc carry a delivery obligation from the first message —…

• "Might could"…

  Non-native English speakers — especially those whose native language stacks modals freely — sometimes write things like: "One thing we might could improve..." This is a double modal. It exists in some regional American dialects (Southern US) but is grammatically incorrect in standard and professional English. Pick one modal: might or could. The right choice depends on intent: "One thing we could improve" — confident suggestion, implies you see a concrete area to fix. This is usually what you mean. "One thing we might improve" — tentative, sounds like you're unsure whether improvement will happen at all. Weaker than you probably intend. "One thing we might want to improve" — works, but adds unnecessary words. "Could" is cleaner. The other trap in the same sentence: "the pipeline I re-run" vs "the pipeline I reran". "Re-run" is the present tense or a noun; if the action already happened, it's reran (past…

• Garbled text before…

  You SSH into a machine and see garbage like ile://host/home/userurrentDir=/home/user before your prompt. Locally everything is fine. What happened? Your PROMPT_COMMAND includes an OSC 7 / OSC 1337 sequence that reports the current directory to the terminal emulator. Locally, WezTerm (or iTerm2, etc.) intercepts these invisible escape sequences. Over SSH with TERM=linux, no terminal emulator is listening — the raw bytes print as text. The fix is a guard condition before wiring __report_cwd into PROMPT_COMMAND: if [[ -n "${TERM_PROGRAM:-}" || "${TERM:-}" =~ xterm|screen|tmux|wezterm|alacritty ]]; then [[ ":$PROMPT_COMMAND:" != *__report_cwd* ]] && \ PROMPT_COMMAND="__report_cwd${PROMPT_COMMAND:+; $PROMPT_COMMAND}" fi When TERM=linux (plain SSH) and TERM_PROGRAM is empty, the function is skipped entirely. No escape sequences, no garbage. After deploying the fix, start a fresh shell — PROMPT_COMMAND is already set in the running session and…

• Short-lived tokens…

  You protect ~/.bashrc.secret with chmod 444 so nothing accidentally overwrites your API keys and passwords. Then your token-refresh script needs to write a new session cookie somewhere — and hits Permission denied. The fix isn't adding a second writable secrets file. It's stop persisting short-lived tokens entirely. Refactor the refresh script to output TOKEN HASH on stdout and let the caller capture it: # refresh_token — reads credentials, prints session token to stdout CREDENTIALS=$(bash ~/bin/refresh_token 2>/dev/null) TOKEN=$(echo "$CREDENTIALS" | awk '{print $1}') HASH=$(echo "$CREDENTIALS" | awk '{print $2}') No file writes. No second secrets layer. The token lives in the process environment for the duration of the operation and disappears when it's done. This works because session tokens are cheap to re-obtain — one HTTP call with stored credentials. The only reason to persist them is avoiding that call, which is almost never worth the complexity of…

• One Telegram Bot +…

  Running the same Telegram bot relay as a systemd service on multiple machines means both instances poll the same bot token. Telegram delivers each update to one consumer only — so messages vanish at random, or land on the wrong host. Both sides think they're healthy; neither is. The fix: one bot per machine, one channel per bot. Each channel becomes a dedicated console for exactly one host. No coordination needed, no distributed locks, no split-brain. To manage multiple bot tokens in a shared dotfiles repo, key them by hostname: # dotfiles — all tokens in one file, encrypted as usual export TG_TOKEN_homeserver="token_aaa" export TG_TOKEN_vps="token_bbb" # relay picks its own token at runtime export TG_TOKEN=$(eval echo \$TG_TOKEN_$(hostname)) Every machine runs the same service file unchanged — hostname resolves to the right token automatically. Adding a third machine is just a new bot, a new channel, and one more TG_TOKEN_<hostname> line. TG Channel:…

• `exec bash` vs…

  After changing your hostname with hostnamectl set-hostname, the current terminal still shows the old name. You want a fresh shell — but bash and exec bash behave differently. Running bash spawns a child process. Your old shell is still alive underneath, and $SHLVL increments by one. Environment changes (like the new hostname) are picked up, but you've added a layer: $ echo $SHLVL 1 $ bash $ echo $SHLVL 2 Nested shells can cause subtle issues — exit only drops you back to the parent, aliases and env vars may differ between layers, and deep nesting is easy to accidentally accumulate. exec bash replaces the current process in-place (same PID). The old shell is gone, a new one takes over, and $SHLVL stays the same: $ echo $SHLVL 1 $ exec bash $ echo $SHLVL 1 This is the clean way to reload your shell config after changing .bashrc, updating $HOSTNAME, or any other env-level change. No nesting, no leftover state.

• Telegram Bot Custom…

  Telegram bots can show a command menu when users type / in a chat. Registering commands is a single API call — no approval, no webhook setup, no special bot-side handling. curl -s -X POST "https://api.telegram.org/bot<TOKEN>/setMyCommands" \ -H "Content-Type: application/json" \ -d '{"commands": [ {"command": "status", "description": "Show active host"}, {"command": "switch", "description": "Switch active host"} ]}' From the bot's perspective, /status or /switch desktop arrives as plain text in message.text — you parse it like any other message. Scope-aware deletion deleteMyCommands supports optional scope and language_code parameters so you can clear commands for specific contexts (private chats, groups, a single chat, a specific language). But there's no API to delete individual commands. The elegant part: setMyCommands always does a full overwrite. Sending an empty…

• nohup Is Insurance,…

  Both prevent a process from dying when you close the terminal, but they work at different stages and with different guarantees. nohup intervenes before launch. It sets the process itself to ignore SIGHUP via sigaction, so no matter who sends the signal, the process won't react. It also redirects stdout/stderr to nohup.out (or a file you specify). POSIX-standard, portable to any shell. disown intervenes after launch. It removes the process from the shell's job table so the shell won't notify it on exit — but the process has no built-in signal immunity. Some SSH/terminal implementations broadcast SIGHUP to the entire process group on disconnect, bypassing the shell entirely. In that case disown alone won't save you. # nohup: know you need it upfront nohup python train.py > train.log 2>&1 & # disown: the "oh crap I need to leave" rescue ./long_task.sh # already running... # Ctrl+Z to suspend, then: bg disown %1 # Belt and suspenders — use both nohup cmd >…

• Prevent Linux OOM…

  When a Linux box slowly bleeds memory over hours, the kernel OOM killer kicks in too late — by then the machine is already frozen. Two complementary fixes: earlyoom kills a hog before the system locks up, and a periodic memory snapshot gives you post-mortem data next time it happens. earlyoom Install and go — on Debian it's one command and the service auto-enables: sudo apt-get install -y earlyoom systemctl status earlyoom.service Defaults (Debian package): kills when available RAM drops below 10% and available swap drops below 10%. Sends SIGTERM first, then SIGKILL. Configurable via /etc/default/earlyoom or override flags in the systemd unit. Memory snapshot every 5 minutes When the machine eventually does die, you want to know what was growing. A systemd timer + shell script + logrotate gives you that with near-zero overhead. The capture script (/usr/local/bin/memsnap-capture): …more

• Attach a GNU screen…

  You have a screen session running in one terminal and want to interact with it from a second terminal on the same host. Two modes: Share it — both terminals see and type in the same session: screen -x <session> Great for pair debugging. Both clients are attached simultaneously. Take it over — detach the other client and bring the session here: screen -d -r <session> Use this when you're switching from SSH to local, or reclaiming a session you accidentally left open elsewhere. Find your session name first: screen -ls If the session belongs to a different user, you'll need that user's permissions (or sudo).

• tmux send-keys…

  When dispatching commands between tmux sessions, tmux send-keys -t <target> '<command>' Enter exits 0 and the command text appears in the target's input buffer — but the Enter never commits. The agent sits idle. The dispatcher sees success. Nothing happened. This hits hardest with long commands that trigger tmux's bracketed paste mode: the trailing Enter gets absorbed into the paste block instead of executing it. Two other failure modes: the target app is in a modal state (dialog, secondary prompt) that swallows Enter, or the input handler is loaded and drops the keystroke. The fix is a verify-and-retry loop after every dispatch: dispatch() { local target="$1" cmd="$2" # 1. Send tmux send-keys -t "$target" "$cmd" Enter # 2. Wait for the target to start processing sleep 3 # 3. Verify it's actually working, not just staged if tmux capture-pane -t "$target" -p -S -10 | tail -10 \ | grep -qE…

  这里记录我的一周分享，通常在周六或周日发布。 懒聪 我们终其一生寻找的应该是，自己喜欢的生活和自己本该成为的人。所以多走点弯路没关系，花很多时间在路上也不要紧。只要你一直在成为自己的路上就行。命运的仁慈就在于，只要你往前走，它总是给路。 One could say in the first quarter-century of my life, that while I was always fascinated by programming, I could never overcome the guilt of not really knowing whether the tool I am building right now isn’t already superceded by some much better implementation someone else has already written 30 or 40 years ago; I could write a TSV-aware search and replace, or I could find out about awk and solve that entire class of problems in one fell swoop, for example. My central conceit is that this is a trap. You need to reinvent a couple of wheels to get to the edge of what we know about wheel-making, not a thousand wheels, and not zero; probably four or five is sufficient in most domains, maybe closer to twenty or thirty in the most epistemically rigorous and developed fields like mathematics or computer science.

• AI coding CLIs all…

  When you need a clean slate — testing, debugging, or isolating a project — each major AI coding CLI lets you override its config directory via an environment variable: # Claude Code CLAUDE_CONFIG_DIR=/tmp/claude-clean claude # GitHub Copilot CLI COPILOT_HOME=/tmp/copilot-clean copilot # OpenAI Codex CLI CODEX_HOME=/tmp/codex-clean codex These replace the entire config directory (~/.claude/, ~/.copilot/, ~/.codex/), so existing sessions, permissions, and plugins won't carry over. Copy the default directory contents if you need to preserve anything. Copilot also has a separate COPILOT_CACHE_HOME for marketplace cache and update packages — setting COPILOT_HOME alone won't relocate those.

• One IP, Multiple…

  In the HTTP era, virtual hosting was trivial: one IP serves many domains, the Host header tells them apart. HTTPS breaks this because TLS handshake happens before any HTTP header — the server must pick a certificate before knowing which domain the client wants. SNI — the standard fix Server Name Indication is a TLS extension where the client sends the target hostname during handshake. All modern clients support it. Nginx uses it automatically — just define separate server blocks: server { listen 443 ssl; server_name a.com; ssl_certificate /etc/ssl/a.com.crt; ssl_certificate_key /etc/ssl/a.com.key; } server { listen 443 ssl; server_name b.com; ssl_certificate /etc/ssl/b.com.crt; ssl_certificate_key /etc/ssl/b.com.key; } Each domain gets its own certificate. Nginx routes based on SNI. Zero extra config needed. When you'd rather use one certificate For a handful of related domains, a SAN certificate (Subject Alternative Name) covers multiple names in one cert: server { listen 443 ssl;…

  I Wrote a git alias using [[ ... ]] and =~. Works fine in my interactive bash. Run the alias and it explodes: $ git co master ... Syntax error: "(" unexpected (expecting "then") First instinct: "but I have bash installed": $ ls -l /bin/bash -rwxr-xr-x 1 root root 1298416 ... /bin/bash $ /bin/bash --version GNU bash, version 5.2.37(1)-release ... Doesn't matter. A git alias starting with ! is hardcoded to run under /bin/sh — it doesn't read $SHELL, doesn't care what your login shell is.

• Run Multiple Claude…

  Use CLAUDE_CONFIG_DIR to point Claude Code at a different config directory — credentials, settings, sessions all go there instead of ~/.claude. mkdir -p ~/.claude-work CLAUDE_CONFIG_DIR=$HOME/.claude-work claude Set up aliases in your shell config for quick switching: alias claude-work='CLAUDE_CONFIG_DIR=$HOME/.claude-work claude' First launch in the new directory triggers the login flow — that's how you get account isolation. Both instances can run simultaneously without interference. Share session history between instances CLAUDE_CONFIG_DIR is all-or-nothing — no built-in way to share just sessions. Symlink the projects/ directory back to the original to get shared session history with separate settings: mkdir -p ~/.claude-work cp ~/.claude/settings.json ~/.claude-work/settings.json ln -s ~/.claude/projects ~/.claude-work/projects This gives you independent config/credentials but a unified session list.

• WSL SSL Certificate…

First, refresh the bundle: sudo apt-get update && sudo apt-get install -y ca-certificates sudo update-ca-certificates That fixes most cases. If not, try a full reinstall: sudo apt-get install --reinstall ca-certificates sudo update-ca-certificates --fresh On corporate networks, you likely need your company's root CA certs. You probably already have them somewhere in your Windows filesystem (.crt or .cer files). Copy them all into the trusted store: sudo cp /c/Certificates/*.crt /usr/local/share/ca-certificates/ sudo cp /c/Certificates/*.cer /usr/local/share/ca-certificates/ sudo update-ca-certificates Skip .pfx files — those contain private keys and are a different format.

• Git Worktree:…

  Need to work on two branches simultaneously without stashing or cloning? git worktree creates a separate working directory that shares the same .git — no duplicate objects, no wasted space. git worktree add <path> <branch> For example, to checkout feature/login into a sibling directory: git worktree add ../my-feature feature/login This creates ../my-feature with the branch checked out and ready to work. Commits, branches, and remotes are shared — it's one repository, multiple workspaces. Day-to-day operations: git worktree list — see all linked worktrees git worktree remove <path> — clean up when done One restriction: the same branch cannot be checked out in two worktrees at once. Git enforces this to prevent conflicting writes to the ref.

• WSL2 Won't Run on…

  Most EC2 Windows Server instances don't expose nested virtualization to the guest OS. WSL2 requires Hyper-V extensions, so it simply won't start. WSL1 works fine — it's a translation layer, not a VM. Enable the WSL feature and reboot in an Admin powershell window: Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux Restart-Computer After reboot, pin the default version to 1: wsl --set-default-version 1 On Windows Server, Add-AppxPackage is often broken or unavailable, so the standard wsl --install route fails. Use wsl --import with a rootfs tarball instead: Now use a non-admin powershell: mkdir $HOME\WSL mkdir $HOME\WSL\Ubuntu Then: wsl --import Ubuntu $HOME\WSL\Ubuntu .\ubuntu.tar.gz --version 1 What you lose with WSL1: no Docker, no real Linux kernel, no systemd, weaker filesystem compatibility. Fine for CLI tooling, scripting, and build environments. If you need a real kernel, spin up a native Linux EC2 instance instead.

• tmux mouse…

  With set -g mouse on in tmux, dragging to select text enters copy mode but the selection stays trapped inside tmux — it never reaches the system clipboard. The fix is a two-line binding that pipes the selection through xclip: # ~/.tmux.conf set -g mouse on # Auto-copy on mouse drag end bind -T copy-mode MouseDragEnd1Pane send -X copy-pipe-and-cancel "xclip -selection clipboard" # Fallback: also copy on simple mouse-up (covers cases where drag is too short) bind -T copy-mode MouseUp1Pane send -X copy-pipe-and-cancel "xclip -selection clipboard" You need xclip installed (sudo apt install xclip). Reload with tmux source-file ~/.tmux.conf. The copy-pipe-and-cancel does three things at once: grabs the selection, pipes it to xclip -selection clipboard, then exits copy mode (which clears the highlight). That's how you know it worked — the highlight disappearing means the text is in your clipboard. Why two bindings MouseDragEnd1Pane only fires on a proper drag. If you…

This bit me in HelloEDi. I wanted to spawn claude -p with CLAUDE_CONFIG_DIR pointing at an isolated dir so the user's global ~/.claude/CLAUDE.md (which carries a personal persona) wouldn't leak into the assistant. .env had: CLAUDE_CONFIG_DIR=/home/davidw/.helloedi/claude-home But my shell already exports CLAUDE_CONFIG_DIR=/home/davidw/.claudeh for my own Claude Code setup. dotenv loaded .env, saw the var already set, did nothing. The server's process.env.CLAUDE_CONFIG_DIR was still the shell's value. The spawned claude happily read the persona from there. The assistant introduced itself with the wrong name. The fix is to never put the canonical var name in .env when your dev environment is likely to export it. Use a project-internal name and translate on spawn: # .env…

• Your .bashrc bails…

  The first non-comment line in most .bashrc files is this: [ -z "$PS1" ] && return It means: if this shell isn't interactive, do nothing. Innocent-looking, but it silently breaks any agent that shells out via bash -c '...' — the child shell gets no PATH additions, no cargo env, no API keys you carefully exported in .bashrc.custom. Your terminal works fine, your CLI agents don't, and the failure mode is some bare command name "not found" that has nothing to do with the actual problem. The fix is to split the file by purpose (env vs interactive), not by file (.bashrc vs .bashrc.custom), and use BASH_ENV as the loader for non-interactive shells. Split env from interactive Pull every export, every PATH= mutation, every . ~/.cargo/env and . ~/.bashrc.secret out of .bashrc.custom and put them in a new file. Call it ~/.bashrc.env. It must be idempotent and produce no output (no echo, no which). # ~/.bashrc.env — env-only, safe for both interactive and…

Two settings, set them once, forget about it. The reason ln -s in git-bash silently turns into cp by default is two unrelated barriers stacked together: Windows non-admins can't create symlinks unless Developer Mode is on.

• WT keeps opening as…

  Your Windows Terminal default tab is opening with admin privileges and you don't remember asking for it.

Worth checking, but it's the second place to look for WT. The first place is settings.json: { "commandline": "C:\\Program Files\\Git\\bin\\bash.exe", "elevate": true, "guid": "{17c3a2bf-...}", "name": "Git Bash" } WT 1.18+ added elevate as a per-profile flag. When it's true and that profile is also pointed to by defaultProfile, every new window silently opens elevated — no UAC prompt at the tab level because the elevation happened at WT launch. Delete the line, restart WT, done. If you still want an admin tab on demand, add a second profile with a fresh GUID and a different name (e.g. "Git Bash (Admin)") that keeps…

• VARCHAR2(4000 CHAR)…

  VARCHAR2(4000) means 4000 bytes, not characters. Most people know this. What's less obvious: VARCHAR2(4000 CHAR) doesn't guarantee 4000 characters either. Under the default MAX_STRING_SIZE=STANDARD, the hard column cap is 4000 bytes regardless of whether you declared BYTE or CHAR. In AL32UTF8, a Chinese character takes ~3 bytes, so VARCHAR2(4000 CHAR) on a column storing CJK text will fail once the actual byte count exceeds 4000 — around ~1333 characters in. To actually store 4000 CJK characters in a single VARCHAR2, the instance needs MAX_STRING_SIZE=EXTENDED (12c+), which raises the limit to 32767 bytes. This is not the default — not even in 19c — and it's a one-way migration that requires running utl32k.sql in upgrade mode. Oracle keeps it off by default precisely because it changes data dictionary behavior and breaks compatibility. Quick check for your instance: SELECT value FROM v$parameter WHERE name = 'max_string_size'; STANDARD = 4000-byte ceiling. EXTENDED = 32767-byte…

• Cloning an EC2…

  AWS console offers three ways to duplicate an EC2 instance, differing in whether disk data is carried over. Create AMI (recommended, full clone) — preserves the system disk, installed software, and all configuration. In the EC2 console, select the target instance → Actions → Image and templates → Create image. Wait for the AMI status to become available (a few minutes to tens of minutes), then go to AMIs → select it → Launch instance from AMI. Adjust instance type, subnet, Security Group as needed. Launch More Like This (fastest, no data) — copies only instance configuration (type, SG, subnet, tags). The system disk is brand new. Actions → Image and templates → Launch more like this. The Launch page opens with config pre-filled; confirm and launch. Good for stateless instances, e.g. web servers initialized via userdata. Launch Template — if the original instance had a Launch Template saved, launch directly from it. EC2 → Launch Templates → select template → Actions → Launch instance…

• Why Vite dev server…

  In development, your frontend runs on localhost:5173 and your API server on localhost:3000. The browser blocks cross-origin requests — that's CORS. Vite's dev proxy solves this by forwarding /api/* requests to the backend, making them look same-origin to the browser: // vite.config.ts server: { proxy: { '/api': 'http://localhost:3000' } } In production this proxy disappears. The built frontend is just static files (HTML/JS/CSS) — no port, no process. Nginx or a CDN serves them, and reverse-proxies /api/* to the backend the same way Vite did in dev: user → Nginx :80 ├── /api/* → backend :3000 └── /* → dist/ static files One port from the user's perspective, no CORS issue. The backend port is always real and needed; the frontend "port" only exists during development because Vite's dev server is a live process.

• Linux suddenly…

  Your Linux box resolves a host to its AAAA (IPv6) record, connects, but the remote isn't actually listening on IPv6. You see telnet hang on an IPv6 address. This happens when your system starts preferring IPv6 over IPv4. One-off fix — force IPv4 for a single command: telnet -4 api.z.ai 80 Permanent fix — edit /etc/gai.conf and uncomment this line: precedence ::ffff:0:0/96 100 This tells getaddrinfo() to return IPv4-mapped addresses with higher precedence than IPv6. Changes take effect immediately — no restart needed. gai.conf is re-read on every getaddrinfo() call, so the next DNS lookup picks up the new rule. Existing connections are unaffected. If /etc/gai.conf doesn't exist, just create it with that single line.

• `--data-raw "$VAR"`…

  When posting multipart form data via curl in a bash script, it's tempting to build the body in a variable and pass it with --data-raw "$DATA". On Linux this often works fine. On Windows Git Bash, it silently breaks — the server receives the request but fields like body come through empty. Two things go wrong at once. First, Windows-style paths (C:\Users\...) passed to bash utilities like tail and file are misread — the backslashes get misinterpreted and the file read returns nothing. Fix that with cygpath: filename=$(cygpath -u "$1" 2>/dev/null || echo "$1") Second, even with the right path, storing the body in a shell variable and passing it via --data-raw is unreliable. Shell variable expansion, CRLF handling, and platform-specific curl behavior all interact badly. The body gets mangled before it reaches the wire. The fix is to bypass variables entirely: write the multipart payload to a temp file and send it with --data-binary @file. Since the post…

• Ctrl+M is the…

  If you're using Codex CLI and want to insert a newline in the prompt box without submitting, Shift+Enter won't work. Ctrl+J works with old versions but not recent ones, now, you have to use Ctrl+M instead. Ctrl+J is the ASCII control character for line feed (\n). Many terminal TUI libraries interpret it as "insert newline" rather than "submit," which is exactly what Codex CLI's input component does. Unfortunately, in the recent version they changed to Ctrl+M instead. Shift+Enter looks like the right key (it works in browser-based chat UIs), but whether it inserts a newline or submits depends entirely on how the TUI library handles raw key events — and Codex CLI's library doesn't treat it as a newline. So: Ctrl+J Ctrl+M to insert a newline, Enter to submit.

  autossh has its own connection monitoring that opens an extra port for heartbeats. But this is redundant — SSH already has native keepalive via ServerAliveInterval. The extra port can even cause problems if it's not available on the remote side. The modern approach: disable autossh's built-in monitoring with -M 0 and let SSH's native heartbeats handle it. When SSH detects a dead connection (after ServerAliveInterval * ServerAliveCountMax seconds of no response), autossh automatically reconnects. Put everything in ~/.ssh/config: Host gateway HostName your-gateway-ip User ec2-user ServerAliveInterval 30 ServerAliveCountMax 3 LocalForward 8080 internal-soap-ec2:8080 Then the command reduces to: autossh -M 0 -Nf gateway -M 0 is the only autossh-specific flag you need. Everything else — host, user, keepalive, even the tunnel — lives in SSH config where it belongs. ServerAliveInterval 30 sends a heartbeat every 30 seconds through the SSH port itself (no extra ports needed), and…

• Newline in OpenAI…

  Shift+Enter doesn't insert a newline in the OpenAI Codex CLI. This isn't a terminal or environment issue — you'll see the same behavior whether you're using iTerm2, the macOS Terminal app, or anything else. It's built into Codex itself. The shortcut for a new line is Ctrl-J. This catches people off guard because Shift+Enter is the standard multiline shortcut in virtually every chat and code editor (Claude Code, ChatGPT web, VS Code, etc.). The muscle memory is strong and there's currently no way to remap it — Codex doesn't expose a keybinding config.

• AWS SSO login on a…

  AWS CLI v2.22.0+ switched the default SSO login flow to PKCE, which requires a browser on the same machine. If you're SSH'd into a server with no GUI, aws sso login just hangs waiting for a browser that doesn't exist. The fix is two flags: aws sso login --profile prod --no-browser --use-device-code It prints a URL and a one-time code. Open the URL on any other device (phone, laptop, tablet), enter the code, authenticate, and you're done. The CLI polls in the background and picks up the token automatically.

• I Automated My Blog…

  I write a lot of short tech notes — things I learn during daily work that are worth remembering. For years the workflow was: learn something → forget to write it down → never find it again. Then I built a pipeline: a Claude Code skill writes the note, a script publishes it to my Chyrp Lite blog, and a cron job keeps the session alive. Now I type /record and it's done — note saved, blog posted, zero friction. The Pipeline Three pieces, each doing one thing: /record skill — Claude writes a tech note from the current conversation pub_tech_note — publishes the markdown file to my blog via curl refresh_chyrp_token — re-logs into the blog monthly to keep the session cookie fresh The Skill The skill is a SKILL.md file that tells Claude how to distill a conversation into a short article. Key rules: find the one non-obvious insight, pick a title that makes someone click, write like a colleague's quick tip not documentation. After writing the file, the skill runs ~/bin/pub_tech_note…

• Automating Chyrp…

  Chyrp Lite has no API — the admin panel is the only way to create posts. But since it's just standard HTML forms, you can automate it entirely with curl. Here's the full pipeline: auto-login, extract CSRF token, create posts. Step 1: Auto-login to get a session cookie The login form at /login/ uses standard URL-encoded POST with a CSRF hash. You need to fetch the login page first to extract the hash from the hidden field, then POST credentials: # Fetch login page, extract CSRF hash LOGIN_HTML=$(curl -s -c /tmp/chyrp_cookies.txt https://blog.example.com/login/) HASH=$(echo "$LOGIN_HTML" | grep -oP 'name="hash"\s+value="\K[^"]+') # POST login curl -s -D /tmp/chyrp_headers.txt -b /tmp/chyrp_cookies.txt -c /tmp/chyrp_cookies.txt \ -X POST https://blog.example.com/login/ \ -H 'content-type: application/x-www-form-urlencoded' \ --data-raw "login=${USER}&password=${PASS}&hash=${HASH}&submit=" # Extract session token TOKEN=$(grep -oP…

• Ansible playbook…

  Ansible loads AWS credentials once at startup. If your playbook runs longer than the SSO role session (typically 1 hour), boto3 has no chance to refresh them — subsequent AWS API calls fail with expired credential errors. The fix: a credential_process profile that boto3 calls each time it needs credentials. Add to ~/.aws/config: [profile prod] sso_session = my-sso sso_account_id = 123456789012 sso_role_name = AdminRole region = ap-southeast-2 [profile prod_sdk] region = ap-southeast-2 credential_process = aws configure export-credentials --profile prod --format process Login once, then run Ansible with the wrapper profile: aws sso login --profile prod AWS_PROFILE=prod_sdk ansible-playbook site.yml Each time boto3 needs credentials, it calls aws configure export-credentials, which reads the cached SSO token from prod and returns fresh role credentials — no browser, no interaction. Don't put aws sso login in credential_process. It opens a browser and will silently hang in the…

• SSH in a script?…

  When SSH runs in a script and the key isn't set up, it prompts for a password — and your script hangs forever. BatchMode=yes disables all interactive prompts (password, passphrase, host key confirmation) and fails immediately instead. ssh -o BatchMode=yes user@host "echo ok" Returns exit code 0 on success, non-zero immediately on failure. Perfect for connectivity checks in CI/CD or Ansible pre-tasks.

• "Download a folder"…

  S3 has no real directories — what looks like a folder is just a key prefix. So there's no "download folder" operation, only "download all objects with this prefix". aws s3 sync is almost always what you want: aws s3 sync s3://your-bucket/path/to/folder/ ./local-folder/ It's incremental — run it again and it only downloads new or changed files. aws s3 cp --recursive works too, but re-downloads everything every time. Filter with --exclude / --include: aws s3 sync s3://your-bucket/logs/ ./logs/ --exclude "*" --include "*.log"

• 论人的自尊心

  你的自尊心和我的自尊心不是一回事。 心理学上至少可以分成三种自尊：稳定型自尊、防御型自尊、以及外在依赖型自尊。它们对于人的成长所起的作用截然不同。 稳定型自尊是成长的基础。 它的特点是肯定自身价值，不因一次成败就忘乎所以或者否定自己。不论身处话题中心还是独处一隅，这样的人始终清醒地知道自己是什么样的人。研究显示，当一个人不刻意维护自我形象时，更容易从批评中汲取养分，也更愿意改变自己。 防御型自尊是成长的阻力。 它的本质是"身份焦虑"——过度在意别人怎么看，批评一来就触发羞耻或愤怒，失败了总是第一时间找理由。这种自尊只是为了"维护形象"。它的表现是回避挑战、不愿请教、热衷于包装。滋养这种自尊，你就只是原地踏步。记住，时间并不会在你停滞不前时停下脚本，不进则退。 外在依赖型自尊是一种波动 。它把自我价值绑定在金钱、地位、排名、他人评价上，评价高时自信爆棚，评价低时自我怀疑。 做为一个人类个体，请一定要准确地识别出你在意的是哪种自尊，滋养助你成长的稳定型自尊，摒弃只会帮倒忙的防御型自尊，以及外在依赖型自尊。

  这里记录我的一周分享，通常在周六或周日发布。 dimlau 我们知道，宇宙中任何有质量的物体，速度都不可能达到光速，但是宇宙本身，在以超过光速的速度膨胀。结果就是，宇宙远端如果有一颗恒星，它发出的光，以光速朝我飞驰而来，却渐行渐远，永远也到达不了我的眼睛——我，永远，看不到它。更诡异的是，组成我躯体的原子，和那遥远深空中的星尘，本是同一个奇点。我也将活过、追求过，带着遗憾死去。 郝靠谱 人不需要去跟AI比阅读量、加工整理能力，但要成为能驾驭机器的人，要持续学习、保持警惕，持续提升甄别信息的能力和那些AI不可复制的能力。 Routine 是人生的复利 2026-01-30 （LimBoy） 我们通常会觉得 Routine 是「自由」的反义词，它让人联想到枯燥的重复、僵化的日程表，或者那种一眼就能望到头的生活，这是一个巨大的误解。 在谈论 Routine 之前，我们先来看看复利公式： 把它放到人生这个大背景下，天赋、机遇和单次努力的强度，构成了那个基础的增长率 r。很多雄心勃勃的人都盯着 r 看。他们试图通过一次通宵工作、一个绝妙的点子或者一次爆发式的冲刺来获得巨大的 F。 但这很难持久。 Routine 的作用，是掌控指数 n。 在很多方面，Routine 就像是定投。如果只有在「感觉来了」的时候才去写作，或者在「状态很好」的时候才去锻炼，你的 n 是断断续续的，增长曲线是锯齿状的。 而一个好的 Routine 是一种承诺：无论我今天感觉如何，无论 r 是大是小，那个 n 都会自动加一。 当 n 足够大时，它就不再是线性的累加，而是指数级的爆发。那些伟大的小说家每天早起写几千字，不是因为他们每天都有几千字的灵感，而是因为他们把写作变成了一种像刷牙一样的生理节律。他们不对抗它，只是执行它。 这就是 Routine 的本质：它把困难的事情自动化，从而让时间站在你这一边。 很多人认为「我不设计 Routine，是因为我不想被束缚」。但真相是：根本不存在「没有 Routine」这回事。 如果你不主动设计你的生活流程，你的身体和环境会为你设计一套。这套「默认 Routine」通常由你的生物本能（懒惰）和外部世界（诱惑）共同编写。 当你拿起手机无意识地刷了两个小时，这本身就是一个极其高效和稳固的 Routine。 既然「默认…

• AI, Juniors, and…

  AI is changing the IT industry’s entry-level landscape. It reduces demand for juniors trained purely under the traditional apprenticeship model, but it does not eliminate the need for juniors altogether. What it changes is the baseline: new juniors are expected to work fluently with AI rather than work around it. This shift raises concerns about experience and continuity, especially as senior engineers retire. However, senior retirement itself is not the core risk. The real issue is how judgment, taste, and practical knowledge are formed and transferred. The traditional apprenticeship model still has real value. Engineers who have built systems end to end, debugged production failures, and lived with the consequences of technical decisions develop a sense of “better” that cannot be learned from prompts or outputs alone. This taste is shaped by cost, failure, and trade-offs. AI can amplify such judgment, but it cannot create it from nothing. At the same time, the old model does not…

  这里记录我的一周分享，通常在周六或周日发布。 如果总是要求帮助，别人就会质疑你的价值；如果从不要求帮助，你就会不必要的搞砸一些事情：身边的人很可能见过这个问题，而且有很成熟的解决方案。 弄懂不明白的问题是最好的学习方式。 碗君西木子 人的天赋是需要被点明的，在此之前与之后，看待事物的方式会有区别，也就是无意识与有意识的区别。 高敏感的人一生只有一个主线任务：内心的平静、深度的人际关系、专业上的精通，以及一种与自身价值观高度一致的生活方式。（这是任务，也是目标。但我觉得它和高敏感与不高敏感没有多大关系，它是普适的，只是有的人意识到的早，有的人晚，而有些人穷其一生也没有意识到。 A journey of a thousand miles begins with a single step. -- 老子 为爱皮 做一件事情，做自己喜欢的事情，干了就开心，而不是干成了才开心。~李诞 Shengyi Wang 我以前不知道是看唐德刚的书还是啥，对中国革命还是建国后政策有句评论：不嫌任重嫌道远。 我觉得这是人性本能，面对艰巨的任务斗志昂扬，但都会低估长久坚持需要的努力。 然后就有人针对“不嫌任重嫌道远”这种人性弱点开始收割韭菜，从 21 天学会 C++ 到写什么“一天内改变人生”的鸡汤文章。 Shengyi Wang 我就想起小时候看到的传说：把人类全部知识编码成一个数，前面加个小数点，然后在一根棍子上这个小数的比例处划一刀，那这根棍子就蕴含了全部的人类知识。 小时候想想没毛病啊，目眩神迷，居然有如此美妙的方法。可惜物理世界测量精度也好普朗克极限也好，都限制了你既不能这么精准的划一刀，划不了几位小数，也不能准确的读出来。 The enjoyment of one's tools is an essential ingredient of successful work. -- Donald E. Knuth 人类哀叹聪明的章鱼只有一两年寿命。又有谁知道是否另一个时空里有更长寿的智能生命哀叹聪明的人类只有不足百年的寿命呢？ 人至晚年，父母亲朋纷纷离世，就连一起玩耍的小伙伴们也日渐凋零，离开这个世界并不会像尚年轻时那样不舍。 就章鱼而言，童年时候，唯一确认的就是努力活下去，而且它们知道自己大概率活不到成年。…

Not only is this easier and a whole lot more fun, it's also more effective. We're going to focus on being light, positive, and non-goal-oriented. We're not going to criticize or complain.
