This has saved Uber a lot of money on compute (I'm one of the devs). If your compute fleet is large and has memory to spare (stateless), performing dynamic GOGC tuning to tradeoff higher memory utilization for fewer GC events will save quite a lot of compute.

jigneshdarji91··on Ask HN: What's your favorite AI tool?
ChatGPT’s Advanced Voice Mode is one of my favorite. We travelled to Paris and Rome last year and just having a “witty, and informative tour guide with knowledge of scientific and cultural history” was very engaging, fun, and useful throughout our trips.

It’s also very useful when reading a book, especially historical ones where auditory medium works well. iPad with stage manager running Kindle and ChatGPT is my usual setup.

jigneshdarji91··on Taking a $15 Casio F91W 5km underwater
> Incredibly, the F91W survives its journey to an official 4,950 meters—an astonishing 16,240 feet—and back.

Findings.

> 4,950 meters under the surface, the pressure is approximately 7,227 pounds per square inch, which is well over three tons pressing on the watch. For context, that’s a Dodge Ram 1500 or a young adult hippopotamus parked on every inch of your F91W. As Americans, we’ll do anything to avoid the metric system, but using scientific terminology, we’re talking about a shitload of pressure.

Appreciate the joke.

jigneshdarji91··on How I ship projects at big tech companies
As a Staff Eng, I strongly related to this. At big tech in Silicon Valley, the Tech Lead archetype does tend to do all the Project Management and, depending on whether your team can afford a Product Manager (eg. Infra team), some or all of the Product Management.

IMO, it's a little unfortunate from a productivity perspective that you have a high performing Engineer also running daily/weekly syncs, doing stakeholder management, and doing upwards management for resourcing. From a personal learning perspective, it's great though. You, as Tech Lead, learn and hone a broader set of skills and not only the Architect or Senior Engineer skillset.

jigneshdarji91··on OpenAI Announces SearchGPT
And I believe for this reason necessarily SearchGPT might come out on top, at least for higher quality content from partnerships.

I've been using Perplexity for the past 3 months on a regular basis and it has replaced DDG for most use cases. It's really nice to have answers directly.

Product comparison/updates/features:

> What's the difference in speedo latex cap vs elastomeric?

> What's new in iOS 18 Beta 4?

Documentation (esp for non-mainstream tools):

> How do i find the sioyek db files? How do I move it to my local iCloud folder instead?

I'd assume SearchGPT's results might be better given the partnerships with publishers and creators vs Perplexity searching the internet. More importantly, Perplexity already did the work of finding Product-Market Fit for OpenAI.

If you enjoyed this, I highly recommend Innovators by Walter Isaacson. It's a very deep and fascinating introduction to the history of computing.
jigneshdarji91··on Ask HN: Is it possible to make FAANG salaries without working there?
I see levels.fyi has a good list of "top paying companies"[1]. Is that helpful?

Side note: The difference at Staff Eng is slightly more wide. Eg. IBM Band 9 pays TC ~$250K while Meta E6 is ~$640K.

Side note 2: From what I understand, Big Tech often brings in Staff Eng from smaller companies to a Senior Eng role. Reverse is also true, Sr Eng at Big Tech are often able to join Staff roles at smaller companies.

I'm so sorry. My comment got mangled.

Color theme and polish feel really good.

It is a beautiful app. Some feedback: - Bug: The emoji isn't changeable on habit creation. - Love that you don't collect data or require login. Color theme and don't choice feel very polished.

I'm curious about the graphs, especially the productive time.
