An oil rig that experienced an explosive decompression in 1983 that killed four divers and one dive tender, as well as badly injured another dive tender.
The divers were killed by a pressure of 9 atm. The pressure the Oceangate Titan experienced was over 400 atm.
The thing that it really helps doing (when you're using it) is avoiding doing multiple things in one commit. Features and refactors and fixes belong in different commits.
With this I can also look at my git log and quickly see on the places where I changed things (rather than style or refactor or docs or tests). This commit, with a few lines did this - not "this change was part of this much bigger commit."
I’ve found it’s too error prone to rely on developers remembering to use conventional commits. But when you use something like cocogitto [0], it makes writing compliant commit messages the path of least resistance. I’ve always liked the idea of conventional commits, but it never felt valuable in practice until I discovered the tooling to make it easy.
I used it extensively on https://github.com/terraform-google-modules. Maintaining up-to-date release notes on 50+ repos would be extremely time-consuming and error-prone without conventional commits.
I follow it pretty closely. I don’t have any automation setup for changelogs or anything at this point, but it’s pretty easy for me, as back in ye old SVN/Trac days there were similar FIX, etc. semantics.
I often have trouble with enough room to have a meaningful subject but the time I include commit scope and Jira ticket number, but I don’t mind, I normally use the body anyway.
"... Joel Nigg has found that excessively irritable infants are more likely to become children who cannot regulate their anger or impulses when frustrated, while excessively exuberant infants are more likely to become impulsive children. In both cases, the development of effortful control is inhibited. These findings have led Nigg to propose that ADHD is not a disorder of inattention or hyperactivity, but instead a disorder of temperament-based self-regulation"
"An increase of 10 dB reduces productivity by approximately 5%."
I'm surprised it isn't more. As someone who is particularly distracted by noise and interruptions, I usually have some music without lyrics playing in noise cancelling headphones whenever I'm in an open office environment.
The real question is when are companies going to pick up on research like this and make changes to maximize productivity. What do offices at FAANG look like?
My productivity increases with regular brown noise -- it "covers-up" the irregular traffic and train noises outside my apartment so my brain doesn't pay attention to it. Brown noise is also pleasant to the ears.
Music: it depends. Any kind of forgettable music like muzak or background instrumental/classical helps. But anything with lyrics distracts me because it engages the language processing part of my brain -- I need that part to do my work. But I know many people who can work while listening to rock and roll.
Also the article makes a difference between cognitive function and effort-task performance.
If I was a mechanic or someone doing a mechanical task, I wouldn't mind blasting heavy metal in the background -- it gives me a "metronome" to sync to. But I wouldn't do the same if I was a tax accountant where I need the cognitive headspace to do careful work.
If we create a quiet office environment, everybody gets to pick their preferred noise via headphones.
I worked as a cook for years while I was younger. There was always a radio on (this is like 1980s-90s). Typical blue collar environment with tons of noise from machinery, raucous people, and the radio.
While doing prep work for the next meal time the music didn't bother me at all (so go through various fridges and the menu and make lists of tasks to prepare then execute on the list interrupted by deliveries, dishwashers quitting in the middle of their shift, and so on - peel carrots, chop onions, clean squid...).
While working the actual rushes on the line (preparing individuals meals to order as part of a team, timing courses to go out and maximizing throughput) the music was extremely annoying to me. My coworkers literally would go crazy without it so it stayed on but it was a major problem for me.
I eventually left cooking for comp sci (long story involving a health condition and a privileged life allowing me to do this) and discovered "psytrance". Finally, I understood how music could make you more productive. Since then I've gotten better at tuning out music with lyrics but it still bugs me when coding or writing.
I wish I could turn to the same genre of music to increase my performance. Like you lyrics are out with exceptions (for some reason I can sort of tune out vocal trance), but some programming I find lend itself well to something like bossa nova, while others I need something highly repetitive like house, and I can't determine ahead of time which will be better. And what really throws me is that usually something like funk will slow me down, but there are times it's the only thing that works. This would all be fine, if I could just roll through the dial, but it takes at least 15 minutes before I know, and it's distracting messing with music until I find something suitable. usually I opt for no music if I'm somewhere quiet, even if there's a good chance music might make me more productive.
Classical music doesn't work for me. It's far too interesting and I'll catch myself pausing my work cause I got distracted by it! Same with jazz and the like.
It has to be some repetitive music/noise so it doesn't catch my attention.
Here is one way to formulate this. You are an information processing machine with certain throughput. Article says 10 dB worth of energy going into your ear causes an average of 5% decrease in your throughput, in the form of processing cost to filter irrelevant bits out. What we don’t know is what that 10dB stimulus is representative of. 10dB of baby crying vs 10dB of equally distributed, unpatterned brown-noise vs 10dB of low frequency predator sounds are by definition are not going to get assigned the same attentional saliency and will have different processing costs. Furthermore, your individual processing machine will accrue certain biases throughout, so same stimulus will not have the same processing cost for everyone. A typical example would be combat PTSD biasing processing towards gunfire, so it would cost more to filter out fireworks later on. In sum, there is a lot of aggregation and averaging going on in this calculation and this is why %5 feels too little a cost for 10 dB.
The study examines a factory workplace which may already have a high-level of background noise. Perhaps the effect is non-linear? Anecdotally, two or three coworkers talking near me doesn't feel more distracting than one coworker on the phone.
Well, the dB scale is already deeply nonlinear. Adding a 50dB conversation to 40dB ambient noise results in… 50.4 dB total noise. Add two more people each talking at 50dB (at the same time!) and the total noise is about 55dB.
"Diet supplementation with ketone bodies (acetoacetate and β‐hydroxybuturate) or medium‐length fatty acids generating ketone bodies has consistently been found to cause modest improvement of mental function in Alzheimer's patients. It was suggested that the therapeutic effect might be more pronounced if treatment was begun at a pre‐clinical stage of the disease instead of well after its manifestation."
The Order of Time by Carlo Rovelli (https://www.amazon.com/Order-Time-Carlo-Rovelli/dp/073521610...) is an amazing and eye opening book on the topic of time. Carlo, a theoretical physicist who specializes in quantum gravity, slowly peels back the layers of the conceptual onion to get to some pretty strange fundamental truths about time.
As a side note, the Audible book is read by Benedict Cumberbach and is a delightful listen.
In Blindsight by Peter Watts, there are a group of revived soldiers that serve as mercenaries. Upon dying, they are 'resurrected' and immediately given a choice to go back to being dead -or- pay off the resurrection fee by serving as a zombie soldier for 8-10 years. If they survive their service, they are free to continue living in whatever mangled state their body currently is. They unaware/unconscious while serving, so they won't have any memory of the horrors that they commit or are acted upon them.
It would be strange to return to your life after dying 10 years ago, but I'd probably take the deal.
