FOXHOUND | GHOST X FEM!READER

um hi 👋👋

this has been rolling around in my subconscious for a while

enjoy x

reader's callsign is Fox (my oc's callsign - apologies)

______________________________________________________________

Freezing wind whipped through the open sides of the helicopter. You, and seven other mates who were all lined up to be candidates for the fifth TASKFORCE 141 operator, were all in five layers of clothing, trying to keep out the icy wind which bit at any square milimetre of exposed skin.

The forest below was blanketed in pale white snow, reflecting up at you as you gazed down over it. A clearing - or, more akin to a tiny break in the thickly wooded area - was visible from the sky.

Even if you could barely see him, you swore you could feel those chilly coffee-tinted irises staring up at you like a laser sight.

Ghost - the man people questioned about his mortality - was tasked with hunting down the eight soldiers packed into one Boeing AH-64E Apache. He was the best tracker the taskforce had - so the soldier who survived the longest would be admitted into the task-force.

The only way your mates could see any chance of survival was staying under the radar for as long as possible.

Which, luckily enough - was impossible for you.

From the second his calculating gaze fell on your form, he'd decided you were the one he'd push, you were the one he was hell-bent on forcing to submit or withdraw from Selection. The two months you'd endured under his command had been nicknamed the ninth circle of hell.

Your muscles burned every night before bed. Your legs felt two hundred pounds heavier than usual.

But you were going to show him that you weren't the runt of the litter.

All of that raced through your mind as you prepared to jump. Calm hands - a stark contrast to how you felt inside - clipped and secured a carabiner to your harness. Within seconds, you were fast-roping down onto the snow.

Your boots crunched as you landed, breaking through a thin layer of ice that had formed over the untouched snow.

Thirty seconds, your mind screamed, thirty seconds and then he's after you.

You were the first one detached from the helicopter, and thus the first one to get a head-start.

Silently, you thanked the man who'd recommended rubber-soled boots. His Scottish accent meant you weren't able to catch his name - did he seriously just say "Soap"? - but that advice had been a godsend, for your shoes barely made any noise against the white-blanketed ground.

You heard a frantic yelp from behind you - fuck - that sounded like Jasper - and your legs worked harder until you were sure you were completely isolated. Ghost had a wicked sense of humour. No doubt he'd track down all of the other soldiers with one hand tied behind his back, and then creep up on you in a way you didn't know was possible for a man of his size - skull-faced bastard.

Then -

CRUNCH.

'Fox.'

You didn't even have to look to know it was him.

In seconds, you were gone - sprinting away like a hare. Now you knew he had your scent, he wouldn't let it go, sometimes going to extreme measures to get you - which he would, by the way.

So why don't you have some fun?

He's gonna love this.

You had wrung a tiny woodland fox's neck after tracking one down, and after making sure deep boot-prints led to it's position, you slid your hunting knife from the underside of it's jaw to the soft, plush and fatty part of it's stomach. After coating your gloves in blood, you scrawled a scarlet message in the white snow, and vaulted up into the lower branches of a tree which had thicker than usual foliage.

Now, you wait.

Sure enough, just as the sun was starting to set, you saw a figure seemingly emerge from the shadows. The huge man moved so silently, as he approached the carcass laid down across a fallen log, with it's innards spilling out from it's chest.

You watched his head tilt, examining the message you'd left for him, before he went completely, eerily still.

Then, a muscle jumped in his neck, before a deep, rumbling growl crawled up from the depths of his throat, a sound which made your knees weak.

Ghost bent down, viciously sawed off the fox's tail with his own hunting blade, and tied it to his belt, before exiting in a way you could only describe as hot.

He was attractive when he was angry... God...

You gave yourself one last chance to proudly survey your handiwork, the maroon stain sinking into the snow.

You're hunting the wrong fox.

Who is....James Proudstar | Warpath? - A Reading Guide

James "Jimmy" Proudstar, is an X-Men affiliated character from Marvel Comics first introduced in 1984. Jimmy is a member of the Yavapai-Apache Nation, and was born in Camp Verde, Arizona. Jimmy grew up idolizing his older brother, John, who would die while on a mission with the X-Men, prompting Jimmy's own path into the world of mutant infighting. Jimmy's story includes topics around the mistreatment of indigenous people (including the medical experimentation that they've suffered), as well as dealing heavily with themes of grief and healing. However, given the nature of American comic books and the lack of diversity among writers, the comics do not always do a good job addressing themes and plots specifically related to Jimmy being Apache.

Many earlier comics do not accurately depict Jimmy's skin-tone or culture, so while in the graphic above I have adjusted some coloring, please be advised that in an unfortunately large number of the following issues...he will look white.

Reading list is under the cut!

From Hellions to X-Force

Jimmy's first appearances are with the Hellions, a villainous group of mutants under the direction of Emma Frost. Jimmy joined their ranks following the death of his brother, John, when he was determined to get revenge on the X-Men- he soon found that he didn't fit in with the Hellions and returned home. Cable approached him about joining the New Mutants but he declined until he discovered that the Hellfire Club (of which Emma was part) had murdered his entire tribe. Now fueled by a desire for revenge against Emma Frost, Jimmy agreed to join the New Mutants right before they turned into X-Force.

New Mutants (1983)#16-17 Uncanny X-Men (1981) #193 Firestar (1986) #2-3 New Mutants (1983) #39, 43, 53-54, 56, 62, 99-100, Annual 7A New Warriors (1992) #Annual 1A Uncanny X-Men (1981) #Annual 15A X-Factor (1986) # Annual 6A X-Force (1991) #1-3 Spider-Man (1990) #16 X-Force (1991) #4-5, Annual 1C Warheads (1992) #4-5 X-Force (1991) #6-7A, 9A-15 X-Cutioner's Song X-Men (1991) #17 New Warriors (1990) #31 X-Force (1991) #19, 21-26, Annual 2, 27-33 New Warriors (1990) #46 X-Force (1991) #34-38 Blaze (1994) #4-5 X-Force (1991) #39-41, 43 Cable (1993) #21 X-Force (1991) #44-53, 55-58 X-Force and Cable '96 (1996) #1A X-Force (1991) #59-61, 63-64 X-Force and Cable '97 (1997) #1 X-Force (1991) #65-66, -1, 68-71 Deadpool (1997) #12 X-Force (1991) #72-93, Annual 1999, 94-98 Cable (1993) #73-75 X-Force (1991) #99-117

X-Corporation

After the dissolution of X-Force, Jimmy would join the international mutant taskforce, X-Corporation.... it didn't last very long....

New X-Men (2001) #133 X-Force (2004) #2-3

X-Men

Jimmy keeps his powers after M-Day and returns to the Xavier Institute where he ends up "joining the X-Men". (It's complicated).

Uncanny X-Men (1981) #475-476, 478-479, 481-482, 484-491

X-Force: Take 2 (Now with Wolverine)

A new X-Force was formed, led by Wolverine (Logan) to do the more....extreme tasks the normal X-Men won't.

Uncanny X-Men (1981) #493 X-Factor (2006) #26 New X-Men (2004) #45 X-Men (1991) #206 X-Factor (2006) #27 (mostly here as set up for the next issue) New X-Men (2004) #46 X-Men (1991) #207 Uncanny X-Men (1981) #498-499 X-Force (2008) #1-6 X-Force: Ain't No Dog (2008) #1B Cable (2008) #6-7, 9-10 X-Force (2008) #7-11 X-Men: Legacy (2008) # Annual 1A, 230A X-Force (2008) #12-13 X-Force/Cable: Messiah War (2009) #1 Cable (2008) #13 X-Force (2008) #14 Cable (2008) #14 X-Force (2008) #15 Cable (2008) #15 X-Force (2008) #16-18, 20

Necrosha, etc.

After the events of Messiah War, Jimmy became embroiled in Necrosha (reanimated mutants were being controlled by Selene and the T-O virus). After fixing that scenario, Jimmy quit X-Force, stayed in Utopia after the schism, and would join the X-Men in a war against the Avengers. (This era technically includes Age of X, but Jimmy doesn't really...do much there so I didn't include those appearances).

Weapon X

After all...that. Jimmy was captured by the restarted Weapon X Program, after being rescued the team Jimmy was on started by renaming themselves "Weapon X" as a way to reclaim the program that had hurt them. During this time, Jimmy started dating Domino...which was certainly a choice on the writer's part....

Krakoa and Fall of X

Like many mutants, Jimmy moved to the mutant nation of Krakoa. While on Krakoa he joined the New Mutants, and would have a chance to reconnect with his beloved brother, John.

Overnight

Last night I downloaded the new release (26) of the Apache NetBeans development environment, intending to try it out. I noticed it wasn't seeing a few of my projects. Further investigation revealed it wasn't recognizing any projects with a particular combination of build files.

Opening an issue on NetBeans seemed like a daunting task, so I procrastinated it to today. And when the time came, I couldn't reproduce the bug at all.

I may never know whether the issue was solved by rebooting my laptop or by getting a good night's sleep!

i trained an AI for writing incantations.

You can get the model, to run on your own hardware, under the cut. it is free. finetuning took about 3 hours with PEFT on a single gpu. It's also uncensored. Check it out:

The model requires a framework that can run ggufs, like gpt4all, Text-generation-webui, or similar. These are free and very easy to install.

You can find the model itself as a gguf file here:

About:

it turned out functional enough at this one (fairly linguistically complex) task and is unique enough that I figured I'd release it in case anyone wants the bot. It would be pretty funny in a discord. It's slightly overfit to the concept of magic, due to having such a small and intensely focused dataset.

Model is based on Gemma 2, is small, really fast, very funny, not good, dumb as a stump, (but multingual) and is abliterated. Not recommended for any purpose. It is however Apache 2.0 Licensed, so you can sell its output in books, modify it, re-release it, distill it into new datasets, whatever.

it's finetuned on a very small, very barebones dataset of 400 instructions to teach it to craft incantations based on user supplied intents. It has no custom knowledge of correspondence or spells in this release, it's one thing is writing incantations (and outputting them in UNIX strfile/fortune source format, if told to, that's it's other one thing).

magic related questions will cause this particular model to give very generic and internetty, "set your intention for Abundance" type responses. It also exhibits a failure mode where it warns the user that stuff its OG training advises against, like making negative statements about public figures, can attract malevolent entities, so that's very fun.

the model may get stuck repeating itself, (as they do) but takes instruction to write new incantations well, and occasionally spins up a clever rhyme. I'd recommend trying it with lots of different temperature settings to alter its creativity. it can also be guided concerning style and tone.

The model retains Gemma 2's multilingual output, choosing randomly to output latin about 40% of the time. Lots of missed rhymes, imperfect rhythm structures, and etc in english, but about one out of every three generated incantations is close enough to something you'd see in a book that I figure'd I'd release it to the wild anyway.

it is, however, NOT intended for kids or for use as any kind of advice machine; abliteration erodes the models refusal mechanism, resulting in a permanent jailbreak, more or less. This is kinda necessary for the use case (most pre-aligned LLMs will not discuss hexes. I tell people this is because computers belieb in magic.), but it does rend the models safeguards pretty much absent. Model is also *quite* small, at around 2.6 billion parameters, and a touch overfit for the purpose, so it's pretty damn stupid, and dangerous, and will happily advise very stupid shit or give very wrong answers if asked questions, so all standard concerns apply and doubly so with this model, and particularly because this one is so small and is abliterated. it will happily "Yes, and" pretty much any manner of question, which is hilarious, but definitely not a voice of reason:

it may make mistakes in parsing instructions altogether, reversing criteria, getting words mixed up, and sometimes failing to rhyme. It is however pretty small, at 2 gigs, and very fast, and runs well on shitty hardware. It should also fit on edge devices like smartphones or a decent SBC.

for larger / smarter models, the incantation generation function is approximated in a few-shot as a TavernAI card here:

If you use this model, please consider posting any particularly "good" (or funny) incantations it generates, so that I can refine the dataset.

weird plane time!!

since i have a random unusual aircraft generator and see a severe lack of any fun airplane facts (especially on the obscure/strange ones), i decided "fuck it" and step up to give tumblr some fun little airplanes.

and for the first post....it's a helicopter.

the Bell YAH-63 (aka Bell model 409).

(link to wiki page)

this fine fella was an experimental attack helicopter created by Bell Helicopters, and it was to compete for the Advanced Attack Helicopter (AAH) competition.

bassically, the AAH competition was exactly what it sounded like; a competition between aircraft manufactures to see who could create the best next attack helicopter for the US Army. more specifically, as wikipedia states: "the Army's broader concern was the task of protecting Western Europe from the numerous Warsaw Pact tanks to the east"

what the army wanted was an attack helicopter that was better than the AH-1 Cobra in both range, firepower and performance. the YAH-63, alongside the YAH-64 (which would later become the well-known AH-64 apache), competed for that title.

unfortunately, the YAH-63 lost. why? well, the Army said that the two-bladed rotors made it "more vulnerable", and believed that the tricycle landing gear was less stable than the taildragger landing gear that the Apache had.

three helicopters total were made. the first one crashed a few months after it's initial flight. the other two were the ones that actually competed.

wikipedia doesnt state were the other two prototypes went. however, searching through google, i found that both examples of them ended up as the United States Army Aviation Museum near Daleville, Alabama:

and as an avigeek who advocates for the preservation of historical aircraft (and especially the rare and weird ones), i always love it when prototypes like these are spared from being scraped/destroyed. they really are a one-of-a-kind.

“This is a way of thinking about the past in which space and time echo each other, and it is by no means particular to the Bandanese. Indeed, this form of thought may well have found its fullest elaboration on the other side of the planet, among the Indigenous peoples of North America, whose spiritual lives and understanding of history were always tied to specific landscapes. In the words of the great Native American thinker Vine Deloria Jr., a shared feature of Indigenous North American spiritual traditions is that they all “have a sacred center at a particular place, be it a river, a mountain, a plateau, valley, or other natural feature... Regardless of what subsequently happens to the people, the sacred lands remain as permanent fixtures in their cultural or religious understanding.” Developing this argument, Deloria contrasts modes of thought that take their orientation from terrestrial spaces with those that privilege time. For the latter, the crucial question in relation to any event is “when did it happen?” For the former, it is “where did it happen?” The first question shapes the possible answers in a determinate way, locating the event within a particular historical period. The second question shapes the possible answers in a completely different way, because it accords a degree of agency to the landscape itself, and all that lies within it, including the entire range of nonhuman beings. The result, in Deloria’s words, is that “the [Indian] tribes confront and interact with a particular land along with its life forms. The task or role of the tribal religions is to relate the community of people to each and every facet of creation as they have experienced it.” For many Indigenous groups, landscapes remain as vividly alive today as they ever were. “For Indian men and women,” writes the anthropologist Peter Basso, of the Western Apache of Arizona, “the past lies embedded in features of the earth—in canyons and lakes, mountains and arroyos, rocks and vacant fields—which together endow their lands with multiple forms of significance that reach into their lives and shape the ways they think.” Stories about the past, built around familiar landmarks, inform every aspect of Apache life. Through these stories features of the landscape speak to people just as loudly as the human voices that historians bring to life from documentary sources.”  ― Amitav Ghosh, The Nutmeg's Curse: Parables for a Planet in Crisis

SYSTEM ADMIN INTERVIEW QUESTIONS 24-25

Table of Content

Introduction

File Permissions

User and Group Management:

Cron Jobs

System Performance Monitoring

Package Management (Red Hat)

Conclusion

Introduction

The IT field is vast, and Linux is an important player, especially in cloud computing. This blog is written under the guidance of industry experts to help all tech and non-tech background individuals secure interviews for roles in the IT domain related to Red Hat Linux.

File Permissions

Briefly explain how Linux file permissions work, and how you would change the permissions of a file using chmod. In Linux, each file and directory has three types of permissions: read (r), write (w), and execute (x) for three categories of users: owner, group, and others. Example: You will use chmod 744 filename, where the digits represent the permission in octal (7 = rwx, 4 = r–, etc.) to give full permission to the owner and read-only permission to groups and others.

What is the purpose of the umask command? How is it helpful to control default file permissions?umask sets the default permissions for newly created files and directories by subtracting from the full permissions (777 for directories and 666 for files). Example: If you set the umask to 022, new files will have permissions of 644 (rw-r–r–), and directories will have 755 (rwxr-xr-x).

User and Group Management:

Name the command that adds a new user in Linux and the command responsible for adding a user to a group. The Linux useradd command creates a new user, while the usermod command adds a user to a specific group. Example: Create a user called Jenny by sudo useradd jenny and add him to the developer’s group by sudo usermod—aG developers jenny, where the—aG option adds users to more groups without removing them from other groups. 

How do you view the groups that a user belongs to in Linux? 

The group command in Linux helps to identify the group a user belongs to and is followed by the username. Example: To check  user John’s group: groups john

Cron Jobs

What do you mean by cron jobs, and how is it scheduled to run a script every day at 2 AM? 

A cron job is defined in a crontab file. Cron is a Linux utility to schedule tasks to run automatically at specified times. Example: To schedule a script ( /home/user/backup.sh ) to run daily at 2 AM: 0 2 * * * /home/user/backup.sh Where 0 means the minimum hour is 2, every day, every month, every day of the week.

How would you prevent cron job emails from being sent every time the job runs? 

By default, cron sends an email with the output of the job. You can prevent this by redirecting the output to /dev/null. Example: To run a script daily at 2 AM and discard its output: 0 2 * * * /home/user/backup.sh > /dev/null 2>&1   

System Performance Monitoring

How can you monitor system performance in Linux? Name some tools with their uses. 

Some of the tools to monitor the performance are: Top: Live view of system processes and usage of resource htop: More user-friendly when compared to the top with an interactive interface. vmstat: Displays information about processes, memory, paging, block IO, and                CPU usage. iostat: Showcases Central Processing Unit (CPU) and I/O statistics for devices and partitions. Example: You can use the top command ( top ) to identify processes consuming too much CPU or memory.

In Linux, how would you check the usage of disk space?

The df command checks disk space usage, and Du is responsible for checking the size of the directory/file. Example: To check overall disk space usage:  df -h The -h option depicts the size in a human-readable format like GB, MB, etc.

Package Management (Red Hat)

How do you install, update, or remove packages in Red Hat-based Linux distributions by yum command?

In Red Hat and CentOS systems, the yum package manager is used to install, update, or remove software. Install a package:  sudo yum install httpd This installs the Apache web server.  Update a package: sudo yum update httpd Remove a package:sudo yum remove httpd 

By which command will you check the installation of a package on a Red Hat system?

The yum list installed command is required to check whether the package is installed. Example: To check if httpd (Apache) is installed:  yum list installed httpd

Conclusion

The questions are designed by our experienced corporate faculty which will help you to prepare well for various positions that require Linux such as System Admin.

Phantoms of the Lost Dutchman Mine

The story about the Lost Dutchman Mine in Arizona is the most popular story told about a lost mine in America.

Modern day prospectors still flock to the Superstition Mountains located 30 miles east of Phoenix in hopes of finding the rich deposits of gold it is said this mine contains.

Many people, unwaveringly hopeful, have bought what they were told was the “real treasure map” that would lead them to wealth and prosperity.

Over a dozen men were killed in the 1800s in pursuit of this gold. It is stated that they may be the phantoms that still protect this treasure today.

After the Mexican War in 1848 the territory of Arizona was transferred to the United States. But with plans made to build a southern transcontinental railroad to Los Angeles the U.S. discovered they needed the land south of the Gila River.

James Gadsden, the U.S. Minister to Mexico facilitated the purchase of another 45,000 square miles between the Gila River and the present Mexican border.

With the onset of the Gadsden Purchase a young Mexican man fled his home in Mexico and went into the Superstition Mountains. It is said he escaped a fathers’ wrath because he had violated the virtue of this mans’ young daughter.

Supposedly, he found a rich deposit of gold in 1852. He then returned to his village and convinced several of the men to return to the Superstition Mountains to help him remove part of the gold before the purchase of the land was complete.

This group mined a large amount of gold and happily headed home. But they didn’t get far before a band of Apaches ambushed them. All were killed with the exception of two young boys who hid. The Apaches not caring for the gold left it where it fell.

It is said the two young boys then buried the gold and ran for their lives. Years later, these two told their cousin about the gold and the 3 men then returned to the Superstition Mountains to retrieve the buried gold and reopen the mine.

As they pursued this they unfortunately met up with a German or some say a Dutch prospector by the name of Jacob Walz–sometimes spelled Welz.

The three Mexican men shared their secret with Jacob Walz and he then promptly killed them.

Walz then recruited his nephew and two friends to help with the heavy labor of digging into the mountainside in order to retrieve the gold. After they completed this task Walz killed the three and buried them deep within the mine.

Several other prospectors who had the misfortune to wander near the Dutchman’s mine suffered the same fate.

When Walz returned to Phoenix rumors about a rich mine began to circulate. Several men tried to follow Walz into the mountains but they never returned to Phoenix. It was believed Walz killed them.

When Jacob Walz died in October of 1891 his family found a shoebox under his bed that was filled with gold nuggets. Supposedly this box also contained a map to the mine but it was written in code, which was never deciphered so the location of the Lost Dutchman Mine remains a mystery.

A well-known legend that surrounds the Lost Dutchman states that if anyone comes too close to this mine they will encounter ghosts.

Several witnesses have claimed to be frightened off by the Apache warriors who murdered the Mexican villagers.

Others state these phantoms are the ghosts of the various men murdered by Walz–most often these are said to be the three whose bodies Walz placed deep in the mine.

Yet other prospectors have claimed they saw the ghost of Jacob Walz. These stories include tales of Walz drawing a gun on these unsuspecting miners.

So be forewarned modern day prospectors–if the Arizona heat or the Superstition Mountains’ rugged terrain does not get to you– a ghost or two just might.
