Fix HDMI audio lag on Retina MacBookPro 2013 (macbook11,1) in Linux

The problem

The HDMI out works just fine out of the box, except that you’ll notice that unless you boot with the HDMI cable connected, you’ll experience some weird audio lag through HDMI. Even worse, after a few seconds, HDMI audio will simply stop working.

Audio drift, lag, and eventually no audio. To rub some salt into the wound, this does not happen under macOS. Classic.

The solution

Well, the good news is that you can get this fixed. Turns out this is because of Linux kernel bug #60769. I can’t comment on the details of how and why the IOMMU feature breaks this particular combination of videocard/HDMI/audio, but I can tell you how to work-around this.

To fix, or at least work-around this, you have to edit your /etc/default/grub and add intel_iommu=on,igfx_off to your kernel boot options:

GRUB_CMDLINE_LINUX_DEFAULT="(...) intel_iommu=on,igfx_off"

Please let me know in the comments, or @diegoe on Twitter, if this helped you, or if you have any insight on why this happens, I’m curious.

Some months with the Fujifilm XF35mm F1.4

A few months ago, Fujifilm had a big sale of lenses and gear, with some drastic discounts like the famous XF35mm F1.4 lens.

Although I couldn’t take advantage of the discounts in the US, I was able to get this lens for a similar price in the local Fujifilm distributor (which I had no clue existed).

Six months later, here are my thoughts on this lens.

Did Bukowski really said “Find what you love and let it kill you”?

While chatting about life and meaning with my still blog-less friend Pedro, I recalled the “famous” quote which according to most of the internet was written by Bukowksi in a letter:

My dear,

Find what you love and let it kill you. Let it drain from you your all. Let it cling onto your back and weigh you down into eventual nothingness. Let it kill you, and let it devour your remains.

For all things will kill you, both slowly and fastly, but it’s much better to be killed by a lover.

Falsely yours,
Henry Charles Bukowski”

I wasn’t able to find out if the quote was really from the poet himself, or just a typical invention of the internet.

In doubt, I simply labeled the letter to be misattributed since I had no further evidence to support its authenticity.

Turns out I wasn’t the only one to ask myself this question, but “Jef with one F” from HoustonPress actually got to the bottom of the matter:

The earliest source we could find for the phrase came from the April 1998 issue of CMJ New Music Monthly. In it David Grubbs interviewed Van Dyke Parks. Parks was asked about how he went about crafting a song, and he went on a roundabout answer involving trial and error and a fear that something wouldn’t work.

“It’s like my friend Kinky Friedman said,” mused Parks. “You’ve got to find what you love and let it kill you. I don’t think any of us should ever forget that.”

When contacted about Friedman being the original source, Friedman’s publicist Cleve Hattersley responded, “Kinky has assured me it is a pure Kinky-ism.”

I guess it’s myth busted… Up until the attribution to Bukowski. For all we know, Mr. Friedman could be pulling our leg :).

12 little moments of randomness

Old shop in Lima’s center

When I got my camera phone, I never thought of it as a camera or as an opportunity to develop a portfolio. I just snapped pictures for the joy of keeping a record of things I liked.

These pictures are moments that I wanted to keep with me. Some are places, some are people, some are just a memento of a specific day. But all of them are my honest desire to keep a moment with me.

I didn’t take them to show off my technique or talent, and I never thought I would ever publish them. In fact, I’m publishing most of them phone raw.

There are interesting moments around us all the time, and some that only we can see and capture. There’s no need for fancy equipment or fancy subjects, you only need your own curiosity.

These are some of those unique moments, those little moments of randomness.
