Just use AdBlock or NoScript to block the popup message from YouTube. Problem mitigated.

Make each program do one thing well. To do a new job, build afresh rather than complicate old programs by adding new "features". (Doug McIlroy) See MS Teams for example on how not to do videoconferencing tool. Bloated hell.

I do switch exactly as mentioned above - white background during day, black or dark gray background during night. Even during night I use small light source behind the display to dim the amount of light emitted by monitor itself.

In Amazon rainforest tribes, 4 year old kids get their first knife/machette and are already completely adapted to survive in jungle. Speak about cultural differences :)

ZFS contains deduplication feature that can be enabled on dataset basis. So dedup is done in background, always, since it's enabled, not during taking snapshot. I've been successfully using dedup to save gigabytes of data on systems hosting many identical Solaris containers (zones). But beware, the dedup feature is memory hog, taking gigabytes of RAM - at least on Solaris.

Actually I did participate on all of the above and more. As test automation engineer and dogfood tester for whole Solaris including hardware, end apps like StarOffice and integrated solutions like SparcSuperCluster and ZFS Storage Appliance. We've been running Solaris+StarOffice on our workstations. Testing the whole OS was really good school. And LDoms too, all kinds of virtualization, VritualBox, Zones, LDoms, PDoms. https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fen.wikipedia.org%2Fwiki%2F... The only stuff I'm sorry about not being opensourced in the latest version is Logical Domains HW virtualization stack, that was really cool technology. Rebooting or upgrading the hypervisor OS didn't affect running guests. It was possible to migrate the guests between hypervisors without rebooting the guest (guest services just seemed to free for about 10-30s, then continue without interruption), reconfigure guests on the fly without rebooting, adding dedicated HW IO parts or board parts to guests, etc. I see that before Oracle acquisition we've managed to opensource only pretty old version of LDoms: https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fweb.archive.org%2Fweb%2F20... It would be great if this would get implemented into QEMU too. Artyom Tarasenko already did good job of adding niagara support to QEMU.

Not only embedded space, but real Space too. Java is running on Mars landers. Java and Solaris were powering the largest banks and stack exchanges in the world. SuperCluster with Solaris and Java was modelling weather predictions at NOAA. Solaris 8 was controlling Boeing jet engines and Boeing engineers stated that this was the only OS they dared to debug during flight. I was stunned reading the discussion under bug against Solaris kernel reporting 32bit int overflow leading to freeze after cca 1 year of continuous operation. Kernel developer suggested reboot could workaround the issue. Customer replied that they're running satellite tracking software on system and any outage might result in losing the satellite position for good. Fix was delivered very quickly after that statement. :-) We also had customers running OS for 18-20 years without reboot.

... OpenOffice too! And DTrace, ZFS, Solaris Containers(zones) as inspiration to LXC/LXD, By open sourcing whole Solaris through OpenSolaris initiative under CDDL, everybody got access to SMF - init V system replacement, Crossbow network virtualization stack and other nice stuff. Another open source activity was OpenSparc, OpenBootPrompt, giving blueprints to Sparc T1000/Niagara HW, which is now more or less integrated in QEMU. Sun was giving full truckloads of high quality engineering to the world. I'm proud to have been the Sun employee.
