Simple minimalist JavaScript metronome

These days, when practicing guitar, I needed a metronome. Whey you type “metronome” on Google Search, it actually brings out a functional metronome – however it has no keyboard shortcut keys. So I decided to write a simple metronome, with keyboard keys, from scratch, to suit my needs.

Knowing the imprecision of JavaScript’s setTimeout function, I implemented a timer that adjusts itself each call, thus having a fairly reliable precision.

The code is so simple I decided not to create a GitHub repository, so I’m just sharing the whole source code here:

Git amend updating date and time

When commiting code on Git, very often I realize I forgot some little detail right after I end the commit operation. This is very annoying. Fortunately, we have the amend command. Recently I found a very cool trick to use with amend command: updating the date and time of the commit together with amend.

So, with those in hand, I’m now using a nice alias on my ~/.bashrc file:

alias gitamend='git commit --amend --date="$(date -R)"'

And my own memory faults are now easily addressed.

Trying out Git Subtree

Currently I have 5 projects on my computer which use WinLamb library. So far I’ve been keeping copies of the library directory on each project; these directories are kept in sync with FreeFileSync Portable. Although this approach works, it’s very cumbersome.

Since each project is versioned as a Git repository, and WinLamb itself is a Git repository on GitHub, I started searching for an alternative, and I choose Subtree over Submodule. Following is a summary of the commands I needed to do on my Windows 7 x64, using Git portable v2.13.1:

1. Remote

Add a remote with the path to the repository of the shared project:

git remote add otherproj --no-tags git@github.com:username/otherproj.git

Or if a local project:

git remote add otherproj --no-tags d:/stuff/otherproj

You can view the remotes with:

git remote -v

2. Subtree

Run the Subtree command:

git subtree add --prefix otherproj otherproj master --squash

This will copy the library into the subdirectory and create a commit, with the hash in the message. It’s unnecessary, but you can provide a custom message for the subtree commit:

git subtree add --prefix otherproj otherproj master --squash -m "Subtreeing otherproj."

3. Updating

To update your project with new library code:

git subtree pull --prefix otherproj otherproj master --squash

This leads us to a nice bash function to our ~/.bashrc file:

function gitsubtreepull { git subtree pull --prefix $1 $1 master --squash; }

Which eases our life when updating our Subtree library:

gitsubtreepull otherproj

So far this approach seems to the better than the old-fashioned directory sync, although it still feels a bit “loose”. I’m still avoiding pushing code from the local repository to the shared library; if I change something, I just copy the code to there, then I update the library repository itself.

Note: beware amending a commit on the remote library. The next time you try to update the dependency, it’s likely to get lost, and you’ll have to remove the subtree and add it again.

After 4 years, SRTEd 1.3.0

So finally I released a new version of SRTEd, my own subtitles editor. Honestly, in these four years I didn’t see a better subtitle editor, I still think it’s the most user-friendly editor out there.

The interface didn’t improve much, but there are many bugfixes and minor UI adjusts. It took so long because I entirely rewrote it using my new Win32 library, which I expect to release as open source soon, together with an article explaining what it is and how to take the best out of it.

It can be downloaded from CNET or Softpedia.

Remembering Randy Rhoads

Randy Rhoads last day was March 19, 1982, 35 years ago today. After influencing so many guitarists, I just want to leave this humble tribute here. I’ve played “Crazy Train” in bands in the past, and it was always a lot of fun.



After publishing the video, I realized the guitar track was a bit too loud in the mix. Well, too late, but not too bad.

I used my Suhr Modern Satin, with Suhr SSV/SSH+ (neck/bridge) pickups, and the POD HD500X connected via USB. After using Billy Gibbons’ .007 signature gauge set exclusively for about one year and a half, I tried the D’Addario EXL130 set again, however with a .012 for the G, as I found on my graphic string tension calculator. It feels very balanced now. I don’t know if I’ll use this custom .008 set on all guitars, but I’m keeping it on the Suhr, at least.

A graphic string tension calculator for guitar

I was assembling a custom string set for my guitar, and for that I needed to calculate the tensions of the string gauges, according to the scale length. Although I found a couple string tension calculators online, pretty much all of them had terrible usability. So I decided to write my own string tension calculator, with the best usability I could think of as an user.

It’s hosted on GitHub Pages: https://rodrigocfd.github.io/string-tension-calc/

I also made it open source on my GitHub account, and I hope to make further improvements.

Fixing bad font rendering on Chrome 54

I’ve been using Google Chrome browser on Windows 7 x64 these days, and it annoyed me how bad the fonts were being rendered. Too light and somewhat pixelated. After a quick search I found some tips, with most fixes revolving around the LCD antialiasing setting, which didn’t work for me. What did the magic was actually installing and configuring an extension named Font Rendering Enhancer.

This extension has only one setting: “font width”. After adjusting it to “50”, voilà, the fonts started looking good. And, of course, allowing it to work in incognito mode.
