I don't know if this affects other versions of Photoshop, but on MacOS Photoshop CC 2017 frequently starts unexpectedly graying out all save buttons when you have made changes to your file and should be able to save.
The secret is to resize and move around the dialog. Drag the lower right corner to make it bigger and smaller a few times, and try dragging the whole dialog to the upper left corner of the screen and making it small.
I use the uBlock Origin browser plugin to filter my LinkedIn Posts, Notifications, and Comments to hide anything containing objectionable topics. uBlock Origin allows you to add custom rules to block web content.
How to use and setup uBlock Origin is beyond the scope of this post. It's not hard, figure it out and then come back. What you want to know how to do is add your own custom rules.
Let's say, for purposes of these example, I want to block all mentions of someone named Grump.
The simplest version: block a single word
The following three rules hide Posts, Comments, and Notifications, respectively, that contain the word "grump", whether as a separate word, or as part of other words, such as "grumpier".
This command shows your system's total, used, and free memory in a human-readable format.
Key metrics:
total: Total RAM.
used: RAM currently in use.
free: Unused RAM.
buff/cache: RAM used for file system buffers and page cache. This is good; Linux uses free RAM for this and frees it when applications need it.
available: The most important metric. This estimates how much memory is available for starting new applications without swapping.
Run it before and after: Run free -hbefore you increase max_children and then after your server has been running for a while under typical load with the new settings. Compare the available memory.
Add or change /etc/cron.d/sysstat to this. This creates a cron jobe to write file /tmp/outage_resource_log.txt that keeps minute-by-minute stats, sometimes useful in troubleshooting slowdowns. However, it's not a great way to do things, it create a small, constant resource drag, so disable it when done troubleshooting.

For confused first-time visitors and other people still acclimating, here is a description of these little tabs to the left, as well as some other features of the site.
Open "Expert Mode" CLI Navigation - this give you the option to switch your browser's display to an old-fashioned terminal mode where you may browse this site, view pages and images by typing text commands. Just like how we used to browse the web back in 1978!
Open Visual Settings - This gives you controls to customize the visual display of this website to your liking: turn up or down the brightness, contrast, color temperature, hue, saturation, dark mode, and earthquake. Settings are saved per browser tab, so they will be remembered for your whole visit.
Open My Eyes - Have you ever been engrossed in your work, when you suddenly realize someone is staring at your screen, watching everything you do over your shoulder? If not, this simulates the experience.
Open Help - This help popup, silly! You just clicked it! Do you not remember?
New - Draggable elements! Several elements on this website, including these tabs, this popup message, and the "Hire Mike" badge in the lower right, can be dragged around with your mouse, to avoid them blocking content. Positions are remembered per tab, so as you navigate around the site, they will stay in the same place for your whole visit.
Enjoy!
CLI Website Navigation
Are you sure you want to switch to viewing this website in the "expert mode" command-line interface?
This will switch to a terminal emulator, load this page, and allow you to browse this website and view its contents by typing text commands.
Plus there might be, y'know, some fun stuff hidden in there. Just for geeks.
