Fwiw, in my Signal app on Android this setting is in

Settings > Notifications > Messages > Show

On a Pixel, I can see some history by going to

Android > Settings > Notifications > Manage > Notification History

I’m surprised (unless they replaced the core tcmalloc algorithm but kept the name).

Indeed, it's not the old gperftools version.

Presumably this is the author given their UNC and SysAdmin background: https://www.linkedin.com/in/treyharris

I found it via a "trey harris sage.org" search on Google.

It seems like you're pretty close with that guess.

https://www.ibisworld.com/us/industry/ohio/bars-nightclubs/1... (2025) estimates there are about 3,000 "bars and nightclubs" in Ohio.

And https://vinepair.com/articles/map-states-with-most-bars/ (2022) estimates there are 1800 bars in Ohio, apparently placing it in the Top 10 of states with the most bars.

What are you referring to with this part?

they have blogged about their cutting-edge protobuf tsunami capabilities.

Not sure if you recall the blog post url or title, but I'm curious to read more.

Their public NTP doc for the "leap smear" also includes some other leap smear proposals: https://developers.google.com/time/smear

You can see some of the cables in https://cloud.google.com/about/locations#network

Do you have a link for Ditto? Searching for "Ditto app" and "Ditto software" returns several possible results for me (e.g. clipboard, music app, managing "copy", content sharing).

It's also mentioned in [1], which starts off

Today we're sharing open source code that can sort arrays of numbers about ten times as fast as the C++ std::sort, and outperforms state of the art architecture-specific algorithms, while being portable across all modern CPU architectures. Below we discuss how we achieved this.

I'm not very familiar with this source [0], but it states "ESA was providing support to the Chandrayaan-3 mission from three of its ground stations located in Kourou (French Guiana), Goonhilly (United Kingdom), and New Norcia (Western Australia)." Although BIK doesn't obviously map to any of those.

No issues when I opened it on mobile Chrome.

Colin (and others?) have been working to reduce the boot time of FreeBSD for a while now. At this point shaving off a few milliseconds is probably a nice win for them.

I believe OP is comparing the visualizations produced by the Auto Pilot system in their Tesla (jumpy) to Waymo's visualizations (stable and coherent).

FWIW, the Use Cases section presents data about the impact in mobile and laptop environments:

On Android, our most advanced simulation that generates memory pressure from realistic user behavior shows 18% fewer low-memory kills, which in turn reduces cold starts by 16%.

...

On Chrome OS, our field telemetry reports 96% fewer low-memory tab discards and 59% fewer OOM kills from fully-utilized devices and no UX regressions from underutilized devices.

If you're interested, check out Abseil's StrFormat [0] for a typesafe printf replacement that uses format strings. You get a nice speed up as well.

Hmm, you may be in luck. That one looks like it's in the parent directory of the second link: http://www.bitsavers.org/pdf/dec/pdp10/TOPS10/1973_Assembly_...

Do you remember if the nickname was "Orange Book" or was it "phone book"? I didn't see the former when searching for more information, but the latter was referenced here [0].

If it's actually "phone book", then [1] seems promising.

I found this [0] 2019 blog post from what looks to be one of the people credited in the blog post (Kostya). It's not directly comparing Android+jemalloc vs Android+Scudo, but it does compare the two allocators and others.

For what it's worth, here's the blog post announcing this release: https://abseil.io/blog/20200212-tcmalloc.

raphlinus had this to say in response to a similar question: https://news.ycombinator.com/item?id=22370494

Seems like Facebook uses it:

"Btrfs has played a role in increasing efficiency and resource utilization in Facebook’s data centers in a number of different applications. Recently, Btrfs helped eliminate priority inversions caused by the journaling behavior of the previous filesystem, when used for I/O control with cgroup2 (described below). Btrfs is the only filesystem implementation that currently works with resource isolation, and it’s now deployed on millions of servers, driving significant efficiency gains."
