In #Solaris development (I arrived at Sun during 2.6) there was a phase, "performance is a lifestyle." It meant you had to think about it all the time, and integrate it into your work. Your classification of "security community" has a similar phrase, one that would also get quoted inside Sun, "security is a lifestyle." You have to think about it all the time, and integrate it into your work, or at least document why you can't at this time, i.e. state the trade-offs.

@CursedSilicon @gettie mostly because #systemD (and it's competitiors) took all the right lessions:

  • Start less
  • Start more in parallel
  • Resolve dependencies to avoid waiting times

And basically everyone (#OpenRC, #Upstart, etc. Even #LaunchD [the #init for #macOS that is literally the SystemD but before SystemD and by Apple] and #SMF [#Sun's SystemD for #Solaris] did that to allow for boot times in secinds, not minutes…

#Introduction

Hello, my name is Christoff.

I live in Illinois, USA, outside the St. Louis area. Below I'll talk about my technology and creative interests, and a bit about me personally. I'm going to hashtag the heck out of this post.

the whole "deadbeef" thing is the magic number from #Solaris for freed memory. I simply chose .monster TLD because it seemed cool and I like "extended" TLDs.

#Technology

I have been using a OpenBSD, #NetBSD, or #GNU/#Linux since the late 1990s as a primary workstation. I used macOS from 2020 to 2025, switching to the #KDE neon distro (KDE plasma is amazing and KDE isn't bloated anymore, yay!).

My current career is as a #pentester where I break into web applications, IP networks, mobile applications (especially #Android), and people to their face or over the phone; code #malware; write documentation; and enjoy helping clients in a third party contractor/consultant role. I started that job change in 2020, when I earned the #OSCP certification at the height of "#infosec twitter" when I did well there.

Previously I worked for about 20 years as a senior-level programmer, and systems, infrastructure, and database administrator. Burnout was very real and I was extremely bored/unfulfilled.

Now that programming and sysadmin stuff isn't my career, I find I enjoy programming and tinkering again.

I am a big fan of NetBSD and always have been. I am not a huge fan of GNU/Linux but I do appreciate things "just working", even if it is full of closed-source binary blobs and other garbage. It was fun in the 1990s.

I know many programming languages but have been paid professionally to code in #C, #Perl, #Python, #PHP, #Java, and #Groovy for big commercial entities like eBay, small companies, and the US government.

I've maintained 99.99% uptime for a 60MM+ platform for years, including failover and backups (that were regularly tested... you test your failover and backups, right?!).

I always wanted to be a cool C and low-level programmer, which I thought for the longest time was being a kernel programmer, but now I know that isn't the life for me.

Emacs is something I've enjoyed since the beginning and I still can't code a #Lisp well. I'd love to be a cool #lisper with #CommonLisp, but haven't gotten there yet. I'm on the #c64 and #embedded #retrocomputing train now.

#Creative

For creative stuff, I aim to do a lot but tend to hop around as interests take me. I could use some discipline there (someday?).

For #music, I have an electric #bass (Fender Jazz) and electric #guitar. I love #jambands (#GratefulDead, #Phish, #Goose) and that's the type of music I like to play along to.

For #art, I like #acrylic and #watercolor painting. I rarely do it, but think about it a lot and love it when I do it. I don't have any skill or talent, but that's not the point. It's for me and no one else.

For #computing, I am venturing into #C64 #demoscene programming and exploration. Not only was I too poor to get one when I was little but I sorta forgot about it over time. The desire to do cool things in a restricted environment where folks are playing in the sandbox, too, is very exciting and attractive to me. I don't know how to code the #Commodore64 stuff yet, but will! Learning the assembly language (I have zero desire to code in BASIC again and I can just code assembly).

#Personal

I live with my soulmate and our five amazing cats in a small town outside St. Louis living a quiet life. Just doing our jobs, taking care of daily life stuff, and enjoying each other and life as much as we can. Ups and downs of life chaos, like anyone else, but we're doing alright!

We enjoy exploring places within driving distance and there are a lot of places to go to.

Currently, we're really into playing two-player games together and just started collecting #boardgames. Right now, we're really digging #SkyTeam, #RoyalGameOfUr, #ForrestShuffle, #SentinelsOfTheMultiverse, and this magnet game I don't know the name of. We have #SpiritIsland and #ArcNova to unwrap and learn. We tried really really hard to get into #ArkhamHorrorTheCardGame but the rules are too complicated and confusing, where it felt like we were doing the wrong thing all the time.

I am 46. I grew up loving Star Wars, Star Trek, #SciFi, reading novels non-stop, horror, and watching movies. I collect classic SciFi books from 1960s and 1970s.

I would perhaps describe myself as an extremely curious person, that loves #puzzles and #mysteries, #exploration, figuring out #HumanBehavior like I'm an alien studying humans (I'm good at it, it turns out), that has a keen eye for detail, remembering random little things, and a good listener. I'm fairly adaptable and fluid in most things, which works well for me. My brain works differently than a lot of people, and while frustrating a lot of the time for things I don't understand fully, it is me and serves me well in niches.

Making people laugh makes me happy. I am a #hacker and #tinkerer.

@ramin_hal9001 except that's yet another package and yet another config file and thus requires #Guix to support the target system. Which may not be the case (i.e. ancient versions of #Solaris or some #BSD-based distro or some weird embedded linux device...

  • So whilst that may be attractive to some (and I don't deny the fact that it has merits) I don't think that me publicly hating #YAML and working on a #GNUfree toybox+musl/linux distro is the target audience of it.

I mean if someone wants to port guix to #OS1337 they are happily invited to do so and I'll gladly accept that contribution, but it's currently not on my agenda...

@ytc1 @DenOfEarth @aka_pugs I know.

And espechally in #ScientificComputing a lot of researchers loved working with #SunMicrosystems and when #Oracle took over that relationship got sour'd instantly due to #Oracle #CEO #LarryEllison...

-> infosec.space/@kkarhan/1146825

One of the big successes of #Sun was that they basically declared a unilateral "ceasefire" in terms of #IP & #Patents re: #OpenSource. Whereas Oracle didn't seem willing to honour that.

  • Without that cooperative atmosphere we saw #OpenOffice devs literally forking off into @libreoffice and projects like #illumos and @openzfs scramble to save what was OpenSource'd and also rescue that.

Obviously #Linux with it's #GPLv2only-Kernel and most of it's Userland could not get 'closed-sourced' like #OpenSolaris which instantly got stomped out by Oracle as they wanted to sqeeze #Solaris for profits and milk their clients in typical Oracle fashion...

Now granted, I do know someone who for most of their life made their money dealing with the intricacies of setting up #postfix, #sendmail and #courier #MailServers on Solaris and if I ask said person about that they give me a kilometer stare, so OFC like a #SysV - #Unix systems Solaris and #SunOS really are one of the reasons #WindowsNT won the "#WorkstationWar" and why - if anyone - #Apple won the last "#UnixWar"...

  • Still I do am sad that I declined that #sysadmin position at a leading research center I'm not at liberty to name and I do know there's OFC still some critical infrastructure running even older Solaris servers...

Infosec.SpaceKevin Karhan :verified: (@kkarhan@infosec.space)@DenOfEarth@mas.to @aka_pugs@mastodon.social I know. Cade in point, #OpenSolaris did have avid users just below that range, and a lot of #ScientificComputing used it, as they previously used #IRIX. And #Sun being #OpenSourve-friendly was the right direction...

@fabiscafe @okapi espechally in the form of an interactive desktop...

  • I could see it valid for multiple shell sessions, but #tmux & #screen cover that pretty well.

  • If one has to login into different machines then chances are #aithentification is centralized anyway.

Needless to say #modernizations like #SystemD don't happen because people like #Poettering are "hobbyless", but because the preexisting status-quo (#SysVinit) was slow, inflexible and error-prone by strict linearity and non-parallelization.

  • With a literal /etc/init file one can literally get a system to hang due to a mistake (i.e. certain call doesn't get invoked correctly), whereas on #SystemD (and competing solutions like #LaunchD on #macOS and #SMF on #Solaris) your desktop / laptop will continue to noot even if it doesn't have a network connection.

Not to mention as Benno Rice explained: 'Shit just gotmore dynamic!': We don't have that one big ass maingrame and serial terminals, instead we have laptops that may he carried around a campus or traveled with all day and that constantly switch between wireless and wired networks and have VPN tunnels open and whatnot...

Is there anyone in #Australia or #NZ, or who would be willing to ship to NZ, who could donate a #SPARC #Solaris (sun4u/sun4v) machine to the building effort for FractalKit? We're running up against some limits and some really bad time sinks, doing all of this on a 650MHz #UltraSPARC IIe is.... really really painful. We know this is a long shot, but if anyone out there has a machine they could donate to this we would be immensely thankful. This porting effort is really important to us but it's not going to be actually useful if a single library takes a day to compile. If you can't help, then please boost? @SolarisDiaspora

Stanislaw Lem - #Solaris. 1981

Klassiker der #ScienceFiction und #Phantastik von 1961. Ein Psychologe erlebt Seltsames auf der Orbitstation beim Planeten Solaris; ein Forscher nahm sich bereits das Leben. Solaris kann humane Schuldgefühle auslesen und daraus "reale" Projektionen erschaffen. So begegnet dem Psychologen plötzlich seine tote Frau, für deren Suizid er Mitschuld empfindet. Ein surreales Zusammenleben beginnt.

Meisterwerk der #SF!

Unix friends: what are the low level calls that can create processes?

I've got fork(2), vfork(2), rfork(2), clone(2), posix_spawn(3) (and spawn(2) on Solaris). Also fork(all|1)x?. OSF/1's nfork(2) I guess.

Am I missing anything else that should be on this list? Unix-like systems only, please (so no CreateProcess or the like). What else should be on that list?

Oracle releases first “enthusiast” Solaris release in three years, promises more regular updates

You'd almost forget, but aside from the enterprise-focused variant of Solaris for which Oracle sells support contracts, the company has also nominally maintained and released a version of Solaris aimed at non-production use and enthusiasts
