Originally a X11 Window Manager.

Extremely powerful for it had a slit. Now it's dead.

Linux users have now tooken it's soucecode and created fluxbox, which is extremely good and much better than BB4Win. Fluxbox DEVELOPMENT VERSION offers Taskbar, and Icon Bar, not needed. As well as a more customizable taskbar and fbdesk for icons. Plus the remarkable tabbing engine, allowing you to group your windows automatically and manually.

Window users can now sort of enjoy Blackbox on Windows as a shell replacement called BB4Win. You can still enjoy your internet explorer by using it instead of explorer for a filemanager. BB4Win isn't as good for sloppy focusing and it doesn't allow you to have tabs, or to shrink the taskbar to as tiny as you want it to, but it's still a good blackbox shell for windows and a good replace of Explorer.
I decided to stop using Windows because BB4Win wasn't as good as my Fluxbox v9.10 for Linux. I just kill explorer when I load up Windows and just use the task manager to load up my very addicticting games that do not have a Linux Port and is too slow for emulating.

A blackbox is an air-tight room or vehicle that contains one or more people smoking one or more American Spirit Blacks. The exhaled smoke and the smoke coming from the Spirit Blacks, unable to escape, circulates and thus is breathed in and is not wasted. Smokers in a hotbox may find themselves totally domed beyond the point of speech after about 30 minutes. Blackboxing is an event that requires some amount of planning, but ensures optimal Black usage.

murderhobo 

In a tabletop game, a murderhobo is a player who murders NPCs indiscriminately. This is normally derogatory, referring to a player who totally ignores quests, dialog, backstory, trade, world building etc.

The term is most common with Dungeons and Dragons, but it can be applied to most RPGs where the player is allowed to kill most quest-giving NPCs and NPC traders. E.g. Elder Scrolls, Fallout, Divinity original sin.

In sales terms, a whale is a prospect that is significantly larger than an organization’s average customer.

Whales are large and extremely difficult to close. Due to their immense size, they are highly sought-after.

A whale is typically identified at first by a whale hunter on the sales team, but often requires cross-discipline participation in order to close; this includes assistance from operations, engineering, creative, client success, and business development teams.
"Shit...the sales director chewed me out on the sales call this morning. He's totally pissed that I have nothing in my pipeline. I've been focused on this one whale for so long that I haven't had time to prospect for normal-sized deals."
