Sometimes TypeScript can cache some things that you don't want it to keep cached. For example, an old lower case filename that doesn't exist anymore.
If this is the case, just restart your TypeScript server. If you're using Cursor or Visual Studio, just open up the command palette (Cmd + Shift + P
on macOS or Ctrl + Shift + P
on Windows/Linux) and type Restart TS Server
.

This is kind of a specific TIL, but hopefully it saves somebody else the time it took me to find the answer.
If you are using the TwiML <Pay> verb there is a noun on <Pay> called <Parameter> which lets you pass parameters to your action.
If your payment provider is Stripe and you want to send custom metadata, you can send a <Parameter> with a name prefaced as metadata_
and it will be added to the Stripe metadata that gets sent out in the webhook.
Here's an example:
<Pay paymentConnector="stripe">
<Parameter name="metadata_testKey" value="value" />
</Pay>
and now the object you receive in your webhook will have the following:
"metadata": {
"testKey": "value"
}
Pressing Ctrl

Say you wanted to have multiple names or aliases for the same command of a Makefile.
Something like this:
server:
rails server
s:
rails server
You can just separate them by spaces to achieve the same result, like so:
s server:
rails server
You can use /i
at the end of a regex to match with case insensitivity.
The regex: /hello/i
Will match HELLO
, hello
, and Hello

Is your Github account attached to multiple organizations? Does your primary address associated with Github get inundated with emails/notifications you don't care to find in your personal inbox?
Let me help you out by sorting your Github notification life. Get an email address to which you can flow relevant notifications and associate them with your Github account. Then head on over to Github > Settings > Notifications > Custom Routing
Click "Add new route" and choose an organization and an email address associated with your account.
As you can see, I have my primary email address with Github. Still, now all relevant notifications from Hashrocket projects will funnel into my Hashrocket email address.
To enable key repeat on mac for an app + Vim, find the bundle identifier for the app you want to enable and use its bundle identifier in the following defaults
command:
# For VSCode
defaults write com.microsoft.VSCode ApplePressAndHoldEnabled -bool false
For example we are enabling for VSCode which is why we use com.microsoft.VSCode
.
If you need to find the bundler identifier for a MacOS application for whatever reason, maybe you're trying to execute some useful defaults
command. You can use a quick AppleScript in the terminal like so:
osascript -e 'id of app "Visual Studio Code"'
> com.microsoft.VSCode
Have you ever needed to log into your Github CI run? Is it a flaky test that's hard to reproduce, and the logging output could be more helpful?
You can log into the CI run while it's going. Try out the Github action Debugging with SSH. Utilizing upterm and Tmux, allows for a session that can be logged into.
Add a step like this to your workflow:
name: CI
on: [push]
jobs:
build:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v2
- name: Setup upterm session
uses: lhotari/action-upterm@v1
A cool feature is that it lets you lock down who can log in via SSH keys. Add a limit-access-to-*
declaration like so:
name: CI
on: [push]
jobs:
build:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v2
- name: Setup upterm session
uses: lhotari/action-upterm@v1
with:
## limits ssh access and adds the ssh public key for the user which triggered the workflow
limit-access-to-actor: true
## limits ssh access and adds the ssh public keys of the listed GitHub users
limit-access-to-users: githubuser1,githubuser2
Then, you can log in via your workflow's 'checks' panel.

In Chromium based web-browsers (Chrome, Brave, etc.) go into your settings and search for site search
.
Once you find the settings, click on Add
under Site Search
. This will give you a form like so:
Search engine
is the name that will be displayed in the address bar when searching
Shortcut
is the string you type in the address bar that will begin the site-specific searching
URL
is the desired search url, putting %s
where your search terms will go.
For example, searching through all of the TILs can be done with
https://til.hashrocket.com/?q=%s
Now with this in place, you should be able to something like the following, to quickly view all TILs on a certain topic:
til vim
Now you can enjoy easily learning about the thousands of things all the Hashrocketeers have learned for themselves over the years!
When you take screenshots on MacOS they are saved with a rather long name, like Screenshot 2023-10-18 at 4.13.56 PM
To remove the timestamp making the names shorter just enter this in your terminal:
defaults write com.apple.screencapture "include-date" 0
After doing that go ahead and run this:
killall SystemUIServer
Now your screenshots will just be saved as Screenshot
and successive screenshots in the same directory will have a number appended to them. (i.e Screenshot 1
, Screenshot 2
, etc.)
By default, screenshots on MacOS are saved to the Desktop. To change this to a specific directory:
First, bring up the screenshot utilities by pressing CMD + SHIFT + 5
.
Next, click on the Options
selector.
Finally, choose a location under Save to
Note: Here is where you can set your screenshot to be on a timer, choose whether or not you want the mouse/cursor to show up on the screenshots, and a change few other options.
You can use Cmd (⌘) + w
in VS Code to close the currently open file.
OnMacOS, if you have multiple input sources for your keyboard, such as multiple languages, you'll have an icon like this in your menu bar that lets you switch between your different inputs:
Instead of clicking the menu icon and choosing your input source, you can cycle through your input sources from the keyboard using control
+ space
I think we've all been there. You're right in the middle of something, you need to brew install a formula, you go to install the formula, and then all of a sudden you're greeted with:
Running `brew update --auto-update`...
and so now you have to wait for all of your formulae to update, just so you can use the one that you need.
Well, if you're in a rush or on a slow internet connection, you can skip the auto update by setting the env var HOMEBREW_NO_AUTO_UPDATE
to 1
.
HOMEBREW_NO_AUTO_UPDATE=1 brew install <formula>
You might find it helpful to throw this into an alias so that you can brew install without updates when you're in a rush, without needing to remember the name of the env var.
From the official docs:
HOMEBREW_NO_AUTO_UPDATE:
If set, Homebrew will not auto-update before runningbrew install
,brew upgrade
orbrew tap
.
Taking a screenshot is super helpful and there are many ways to do it. My go to on the Mac is the keyboard shortcut cmd+shift+4
. This brings up a crosshair to select which part of the screen you want.
When you're done selecting you the image will be added to wherever you've configured screenshots to go. Normally the default is directly to your Desktop.
To add this screenshot directly to your pastebin you can do an alternate shortcut of cmd+ctrl+shift+4
. Then you can just paste the image wherever as soon as you're done. This is awesome but is a hard keystroke for me. However I discovered that you can use the original cmd+shift+4
to activate the crosshair but it can be redirected to the pastebin if you hold ctrl
before you click to finalize the screenshot'd section.
Hooray!
When using ⌘+d
to create multiple cursors in VSCode, each cursor has its own independent clipboard. With each cursor you can copy different text selections and paste them separately. 🤯
If you don't know what Hot Corners are, check out this post.
Say you want to utilize the Hot Corner for Lock Screen, but don't want to type in your password every time you accidentally hit the corner of your screen. Well, you can add modifier keys when selecting a hot key.
To do this, simply hold down your preferred modifier key (Command, Shift, Option, or Control , or a combination of these keys) while selecting a shortcut from the dropdown. Now whenever you move your pointer into the corner of the screen, your shortcut won't fire unless you're also holding down that modifier key.
On macOS you can take advantage of Hot Corners
, which are shortcuts activated by moving your pointer into a corner of the screen.
Currently, you can only select from a handful of options, such as Mission Control, Launchpad, Lock Screen, Quick Note and a few others.
To customize each of the four corners, on macOS Ventura 13, it can be found under System Settings->Desktop & Dock->Hot Corners
If you're on a different version, you can see exactly where the setting is located here.
A client has their RDS postgresql databases locked down to only allow connection from their EC2 instances. I found an easy way to connect with my local clients.
In ~/.ssh/config
add something like
Host prod.client
User ubuntu
Hostname prod-ec2-instance.example.com
LocalForward localhost:5433 rds-gibberish.us-west-1.rds.amazonaws.com:5432
IdentityFile ~/production-ec2-key.pem
In ~/.pg_service.conf
save the user, database name, and password
[client-prod]
host=localhost
port=5433
user=rds-user
dbname=client-production
password=blablabla
Now you can start your ssh tunnel in 1 terminal:
ssh prod.client
And connect with any postgres client tool (pg_dump
, psql
, etc.) in another:
psql service=client-prod
Well you just saved a production password to a plain text file, and now you can easily connect and muck things up in production. Make sure your machine is secure and be careful and stuff.
In MacOS you can copy a file or folder's pathname by right-clicking on the file and then holding down the option key. You will then see an option to copy the file/folder's pathname.
You can get android crash logs with adb

To explicitly remove a new line at the end of your string, use a |-
after your key definition:
---
multiline_text: |-
Let me tell you a story...
About my multi-line string.
other_key: "I'm another key"
This would output a string like so for multiline_text
:
Let me tell you a story...\nAbout my multi-line string.
To explicitly add a new line to the end of your string, use a |+
after your key definition:
---
multiline_text: |+
Let me tell you a story...
About my multi-line string.
This would output a string like so:
Let me tell you a story...\nAbout my multi-line string.\n
For the times when you have a larger bit of text or a string with new lines, this may come in handy
To preserve new lines, use a |
after your key definition:
---
multiline_text: |
Let me tell you a story...
About my multi-line string.
This would output a string like so:
Let me tell you a story...\nAbout my multi-line string.
Quick answer: Space Bar
Have you ever found yourself filling out fields in a form, tabbing over to each field as you fill them out, only to come across a dreaded, check-box field that painstakingly makes you reach all the way across your desk to the mouse, just to check this box?
Well, your suffering is over. Simply press the space bar to toggle the check-box and be on your way.
From the chrome dev tools use (⌘ + ⇧ + p) and enter Sensors to get there faster.
On mac, you can use the shortcut CMD + K +W to close all of your open files in the vscode editor. If you have unsaved changes you will still be asked if you want to save or discard them so don't worry about that.
How many times have I wanted to do this but then had to either go to Firefox or look for a Chrome extension?!
Well it turns out this functionality is available in Chrome from the dev tools command palette.
Once the palette is open, start typing screenshot. You'll be provided with all the options Chrome has. Once of them being "Capture full size screenshot".
I had no idea that Google Chrome had a command palette!
Once your dev tools are open, you can activate through the interface by clicking the 'more' icon and then 'Run command' like so:
or by cmd+shift+p (on a mac). Coincidentally this is the same keyboard shortcut as the command palette in Visual Studio Code
Now you'll see the palette which gives you direct access to a lot of Chrome's hidden functionality!
If you want to open a new tab in iTerm in your same working directory, you can use the following steps:
Now your new shortcut will open a new iTerm tab in whatever directory you have currently open.
Have you ever needed to take a screenshot just to send it to somebody, but then you are left with the cumbersome chore of having to actually delete the screenshot before they pile up on your desktop like a pile of dirty laundry?
Well, I am here to save you those 5 seconds you've been missing out on so you can enjoy that next sip of coffee--guilt free.
When taking a screenshot with CMD + shift + 3
, hold down control
as well.
When taking a screenshot with CMD + shift + 4
, hold down control
while dragging the crosshairs to select a section of screen to capture.
Now, instead of saving to your default screenshot location, it will just copy it to your clipboard. You can now just paste the image into your message with no cleanup necessary.
TL;DR
Hold down control
when taking a screenshot to copy it to the clipboard.
TIL that you can easily go to the lock(sleep) screen on OSX with the following keyboard shortcut:

Direnv can execute shell scripts, so given that your env file is encrypted, you can automatically have it become decrypted for you:
───────┬──────────────────────
│ File: .env
───────┼──────────────────────
1 │ STRIPE_PK="123456789"
2 │ API_KEY="qwertyuiop"
───────┴──────────────────────
Say is was encrypted:
ansible-vault encrypt --vault-password-file config/master.key .env
cat .env
───────┬─────────────────────────────────────────────────────────────────────────────────

Now that we have an encrypted .env file, we just need direnv to decrypt it whenever we're in our directory:
───────┬────────────────────────────────────────────────────────────────────────────────────────────────
│ File: .envrc
───────┼────────────────────────────────────────────────────────────────────────────────────────────────
1 │ export $(ansible-vault decrypt --vault-password-file config/master.key --output - .env | xargs)
───────┴────────────────────────────────────────────────────────────────────────────────────────────────
Output:
$ cd rails_app
direnv: loading ~/dev/rails_app/.envrc
direnv: export +API_KEY +STRIPE_PK
echo $API_KEY
qwertyuiop
Now whenever we enter the directory, we will have the unencrypted env vars, but the file remains encrypted on disk. For whatever that's worth.
Sed can remove a line in a file by its number with '<line number>d'

I'm trying to be one of those cool kids that doesn't have to tak their hands off the keyboard. You know the type. So I looked up GitHub's keyboard shortcuts (which are expansive).
Turns out they have a command palette reminiscent of spotlight on mac. Open with (ctrl || cmd)+k
.
Have you ever wanted to script a shell? Do you use kitty? Well then the kitty @

After using Magnet, a window manager in OSX, I remembered hearing that there was a similar facility built into Windows. Turns out, they are very easy-to-remember shortcuts for resizing windows.
Win + Right Arrow
- Snap to right half of screen** Win + Left Arrow
- Snap to left half of screen** Win + Up Arrow
- Maximize current window Win + Down Arrow
- Minimize window if not currently maximized **(will maximize the window if it is currently split on the opposite side of the screen)
There's a few others too, but these 4 I'm finding super useful. If you're interested in other Windows shortcuts, I found some other cool ones in this Lifewire article
One can keep the most recent n files in a directory with just three shell programs: ls
, tail
, and xargs
.
Here is an example to use in a nightly database backup cron job:
#!/bin/bash
# Keep last 5 files ending in .dump
# Don't forget to
# Installation
# 1. cp pg-backups.sh /usr/local/bin/
# 2. chmod u+x /usr/local/bin/pg-backups.sh
# 3. Set the DB variable
# 4. Set the BACKUP_DIR variable
# Example usage for cron to run at 4:05 am every day:
# 5 4 * * * /usr/local/bin/pg-backups.sh
DB=mydatabase
BACKUP_DIR=/mnt/object/production/db-backups
DATE=$(date "+%Y-%m-%d_%H%M")
pg_dump -Fc $DB > $BACKUP_DIR/$DATE.dump
/bin/ls -t $BACKUP_DIR/*.dump | tail +6 | xargs rm
Using sqlite to persist data is superfluous on heroku, duh, but sometimes a third party service wants my rails app to read configuration in a sqlite db file. In order to read the read-only database file, I need to install the sqlite3
gem. To get this to work on heroku I needed to do two things:
heroku buildpacks:add --index 1 heroku-community/apt
Then create an apt file:
# Aptfile
libsqlite3-dev
libsqlite3-0
Did you know that you can quickly and easily display or send someone your SSH public keys located on Github?
Just got to https://github.com/[USERNAME].keys
So in my case retrieving https://github.com/mattpolito.keys
would provide all of the public keys I have added to Github.
You can view the last modified time of a file with the date
program and -r
flag:
$ date -r Gemfile.lock

Even if your operating system enables key repeat, VSCode will disable it. To turn it on you need to update a default value and restart vscode:
defaults write com.microsoft.VSCode ApplePressAndHoldEnabled -bool false
osascript -e 'tell application "Visual Studio Code" to quit'
osascript -e 'tell application "Visual Studio Code" to activate'
TL;DR in the command palette choose "Workspaces: Configure Workspace Trust" and change "Start Prompt" to "never"
VSCode has a nice security feature warning about the risks of unknown file authors, but it is too naive to be useful; it actually has the reverse effect of being insecure (due to the fact most of these folders have been used in vscode for years before this feature was introduced). For example, I have over 200 projects on my machine:
ls ~/dev | wc -l
213
The start prompt is simply training me to continually click "Yes I trust this code" over and over again, not only does this have no effect, but actually has a negative effect of making VSCode think I gave careful consideration to the folder, when instead, I was just trying to open my files.
