playonbsd with TrueOS: It’s Getting Steamy in Here and I’ve Had Too Much Wine (https://www.trueos.org/blog/playonbsd-trueos-getting-steamy-ive-much-wine/)
We’ve done a couple of tutorials in the past on using Steam and Wine with PC-BSD, but now with the addition of playonbsd to the AppCafe library, you have more options than ever before to game on your TrueOS system. We’re going to have a look today at playonbsd, how it works with TrueOS, and what you can expect if you want to give it a try on your own system. Let’s dive right in!
Once playonbsd is installed, go back to your blank desktop, right-click on the wallpaper, and select terminal. Playonbsd does almost all the configuring for you, but there are still a couple of simple options you’ll want to configure to give yourself the best experience. In your open terminal, type: playonbsd. You can also find playonbsd by doing a fast search using Lumina’s built-in search function in the start menu after it’s been installed. Once opened, a graphical interface greets us with easy to navigate menus and even does most of the work for you.
A nice graphical UI that hides the complexity of setting up WINE and Steam, and lets you pick select the game you want, and get it setup
Start gaming quicker, without the headache
If you’re a PC gamer, you should definitely give playonbsd a try! You may be surprised at how well it works. If you want to know ahead of time if your games are well supported or not, head on over to WineHQ and do a search. Many people have tested and provided feedback and even solutions for potential problems with a large variety of video games. This is a great resource if you run into a glitch or other problem.
Weird Unix thing: 'cd //' (https://jvns.ca/blog/2017/02/08/weird-unix-things-cd/)
So why can you do ‘cd //tmp’, and it isn’t the same as ‘cd /tmp’?
The spec says:
An implementation may further simplify curpath by removing any trailing characters that are not also leading characters, replacing multiple non-leading consecutive characters with a single , and replacing three or more leading characters with a single . If, as a result of this canonicalization, the curpath variable is null, no further steps shall be taken.
“So! We can replace “three or more leading / characters with a single slash”. That does not say anything about what to do when there are 2 / characters though, which presumably is why cd //tmp leaves you at //tmp.”
A pathname that begins with two successive slashes may be interpreted in an implementation-defined manner
So what is it for? Well, the blog did a bit of digging and came up with this stackoverflow answer (http://unix.stackexchange.com/questions/256497/on-what-systems-is-foo-bar-different-from-foo-bar/256569#256569)
In cygwin and some other systems // is treated as a unix-ified version of \, to access UNC windows file sharing paths like \server\share
Perforce, the vcs, uses // to denote a path relative to the depot
It seems to have been used in the path for a bunch of different network file systems, but also for myriad other things
Testing out snapshots in Apple’s next-generation APFS file system (https://arstechnica.com/apple/2017/02/testing-out-snapshots-in-apples-next-generation-apfs-file-system/)
Adam Leventhal takes his DTrace hammer to Apple’s new file system to see what is going on
Back in June, Apple announced its new upcoming file system: APFS, or Apple File System. There was no mention of it in the WWDC keynote, but devotees needed no encouragement. They picked over every scintilla of data from the documentation on Apple’s developer site, extrapolating, interpolating, eager for whatever was about to come. In the WWDC session hall, the crowd buzzed with a nervous energy, eager for the grand unveiling of APFS. I myself badge-swapped my way into the c
