2 steps to ssh without passwords

Situation: You are on machine A, and you want to log in machine B without having to enter your password each time.

On machine A:
type: ssh-keygen -t rsa

then press enter for default settings, and make sure you don't enter any paraphrase.

Now, you need to send your public key to machine B.

type: cat .ssh/id_rsa.pub | ssh b@B 'cat >> .ssh/authorized_keys'

That's it !

async promises in a sync way?

This blog post title is pretty confusing - but if you get to read this blog post by Google, it actually makes sense. It's actually pretty cool. Not that I don't like callbacks or promises, but I can see this being useful in more complex examples. async function fetchDogPics(url) {   try {     //this looks synchronous but it isn't...     const response = await fetch(url);     await response.text();   } catch (err) {     console.log('failed', err);   } }

Git commands cheat sheet (in progress)

### Use case: Working on 2 dev branches and merging one into the other and want to revert git checkout dev_branch git merge my_new_feature // merging my branch into develop Ooops, now I realized `my_new_feature` has something wrong git revert -m 1 <sha of merged commit> OR git revert HEAD -m 1 means we keep the parent side of merge ( dev_branch  branch) ### Fetch their new commits and merge to your branch git fetch protected_repo Committed but not pushed to remote. Want to get rid of latest commit git reset --hard HEAD~1 Get a branch from a forked repo to your own repo (or to your own forked repo) git reset HEAD~1  Get a branch from a forked repo to your own repo (or to your own forked repo) git fetch git@github . com : theirusername / reponame . git theirbranch : ournameforbranch Associate your local copy to the upstream branch git remote add repo_name https://github.com/theirusername/their_repo.git Fetch their new commits and merge to your branch git

Chrome dev tools - secret weapon?

When I started working back in 2010, we used to support IE7. I still remember how much of a paint it was to debug javascript code. With IE8/IE9 debuggers, what I learned is patience, rather than figuring out how to fix all those weird bugs that *always show up *only in IE. The debuggers were so slow. Also back then, firebug was the norm. Chrome dev tools was relatively new and most people I knew did not use it. I liked Chrome so I sticked with it. Now, it's a tool that I use almost every day. In fact, I try to spend some time and follow what's new with the dev tools. I also spend some time experimenting with soon to be features/apis on Chrome Canary. This year, well last year... (2016), I've been pretty busy and haven't had much time to look at the new features. But today, I spent a few hours catching up on the last Google I/O and watch what's new with the dev tools. I wanted to share this link and give back some love to the chrome dev tools by writing this post.
