Quantum Computing: Because Waiting is So Last Century

Posted on 2025-07-02 by Delta

So, the brainiacs at the University of Southern California finally did it. They used one of IBM’s fancy 127-qubit quantum computers and solved a puzzle that would make your average classical computer cry itself to sleep. The headline? Quantum machines are exponentially faster. That means the speed difference doesn’t just grow a little, it explodes like your grandma’s cooking when she forgets the oven is on. They tackled something called Simon’s problem, which is basically a quantum nerd’s version of a Rubik’s Cube.
Spoiler alert: classical computers are stuck trying every combo like a hamster on a wheel, while quantum computers just wave their magic qubits and boom!!! done. And yes, this speedup is unconditional. No smoke and mirrors here. No "maybe if" or "probably when" just straight up quantum supremacy dropping the mic. Of course, these quantum whizzes didn’t get here by accident. They had to fight off error after error with fancy new tricks to keep those qubits from flipping out. And unlike past claims that sometimes sounded like sci-fi, this is legit proof that quantum computers aren’t just a nerd fantasy anymore. Now, before you start tossing your ancient Windows PC out the window, keep in mind that this tech still has a long way to go before it can do your taxes, play your video games, or find that one file you lost last year. But hey, at least we know the future won’t be stuck running Excel macros forever. So while your Windows XP rig is still chugging along, quantum computers are already somewhere in 2040, laughing and solving problems you didn’t even know existed.

RAR Files and the Art of Wasting Everyone’s Time

Posted on 2025-07-01 by Delta

RAR files suck. Not just in a "mild inconvenience" kind of way, but in a "why are you still a thing" way. Let’s talk about it. First, ZIP files. They're simple, clean, and just work. On Linux, you run unzip and boom, you’re in. On Windows, you double-click and it opens like a folder. Even macOS plays along. No weird errors. No rituals. Just your files, ready to go. ZIP is the golden retriever of file formats. Loyal, easy-going, always there when you need it. You could probably unzip one on a microwave. Now TAR. Combine it with gzip or bzip2 or xz and you’ve got .tar.gz, .tar.bz2, .tar.xz. These are the Linux power tools. TAR keeps file permissions, symlinks, timestamps, everything. It’s made for real work. You want to back up a server? TAR. You want to send your buddy a meme folder? ZIP. You want to ruin your day and theirs? RAR. Here’s where it gets stupid. RAR is a proprietary format. It’s closed-source. That means if it breaks, you can’t fix it. You just sit there, helpless, while unrar spits out errors and disappointment. And on Linux? You often need the non-free version of unrar. Because apparently, freedom stops mattering once the file has a .rar at the end. It gets better. RAR isn’t natively supported anywhere. Not Windows. Not macOS. Definitely not Linux. You always have to install something extra. It's like the one guest who shows up at your house, eats your food, and then asks you to drive them home. And don’t even get me started on multi-part RAR files. .r00, .r01, .r02... What is this, a file or a math test? I just wanted one folder, not an episode of CSI: File Extraction. So let’s review: ZIP is fast, portable, and plays nice with everyone TAR is powerful, smart, and made for grown-ups RAR is annoying, old, and smells like cracked software from 2006
If you’re sending me RAR files, we’re not friends. Send a ZIP. Be a decent human being.

When You Spend Millions on Firewalls but Karen Resets MFA Over the Phone

Posted on 2025-06-30 by Delta

Scattered Spider is now hijacking airlines and executive accounts using the most advanced hacking tool known to man: a phone call. That’s right. No malware, no exploits, no USBs taped under desks. Just a bored teenager with a LinkedIn tab open and a decent fake voice saying, “Hi, I’m the CFO, I forgot my MFA, help?” And the help desk, trained for exactly zero seconds in basic skepticism, says, “Of course, Mr. Executive, let me just hand you the keys to the kingdom.” The FBI has issued a warning, which is adorable, considering these companies still haven’t figured out that phone calls from strangers shouldn’t result in privileged access to internal networks. But sure, let’s pretend this is a new threat and not the same old con, just wearing a lanyard this time.

The attackers gather personal data like SSNs and birthdays from the vast ocean of already-leaked information, impersonate execs, and call support lines until someone caves. Once in, they surf through Azure, VMware, CyberArk and more, collecting sensitive data and occasionally sprinkling in some ransomware for flavor. The corporate response? Panic, blame the help desk, patch nothing, and keep buying overpriced closed-source security tools that light up like Christmas trees and stop absolutely nothing. This isn’t even hacking anymore. It’s theatre. It's cosplay. These companies are running billion-dollar infrastructures with the operational maturity of a school group project. Multi-factor authentication? Completely useless if Karen from Tier 1 IT will gladly reset it for the guy who sounds confident on the phone. And yet, they keep treating open-source solutions like they’re radioactive. God forbid anyone use transparent, auditable, community-reviewed software when you can just license another SaaS "zero trust" solution that your attacker can access with a convincing fake cough and a vague mention of being locked out of their Okta account. The moral of the story: your security isn’t a fortress, it’s a cardboard set. And Scattered Spider just blew it over by exhaling.

How I Gaslit Myself Into Thinking I Knew Networking.

Posted on 2025-06-29 by Delta

So I bought this MikroTik router from a guy who apparently thinks he works for the CIA. Because instead of, you know, giving me the admin credentials like a normal human being, he changed them. Without telling me. Like it's some sort of top-secret government-issued router and I'm just some civilian who should be grateful it even powers on. Naturally, I call him. Politely, of course. By politely I mean aggressively passive-aggressive with just the right sprinkle of “oh wow that’s super helpful of you.” He responds with a calm “yeah I always do that.” Oh okay. Cool. Love that for me. Eventually I manage to log in. Miraculously. I don’t even know how. Probably divine intervention or maybe the router just gave up and let me in out of pity. Once inside, I think hey, let’s clean things up. Tidy the config a bit. Just a quick refresh. Famous last words.

I proceeded to absolutely destroy everything. Firewall rules? Deleted. Bridges? Gone. DHCP server? Obliterated. Every single setting that made the router functional? I deleted like I was speedrunning a disaster. Then, because clearly I hate myself, I restarted it. Guess who can’t access it now. Guess who bricked their router without physically breaking it. Guess who still refuses to call the guy back out of sheer stubbornness and pride. That’s right. Me. Now I’m reading MikroTik documentation like I’m studying for the final boss fight. Watching tutorials by dudes with thick accents and dead eyes. Googling things like “how to un-destroy your MikroTik router because you got cocky and now it’s personal.” I didn’t choose the networking life. The networking life chose violence and dragged me into it.

Freedom, Visas, and Other Absurd Fantasies

Posted on 2025-06-26 by Delta

I was all set to travel to Canada for FSF40 to talk about software freedom, community resilience, and how Iranian techies are basically magicians for building anything under a digital iron curtain. My elevator pitch was ready, bags half-packed, heart full of hope. And then… Middle East happened

Iran and Israel decided to play "12 Days of Boom" — a festive little exchange of missiles, blackouts, and existential dread. Just to spice things up, someone hit the big red "shut down the internet" button over here, as if that would fix anything besides morale. Now the war seems "over" (whatever that means), and I’m stuck with one tiny, bureaucratic problem: how the hell do I convince a Canadian visa officer that I will come back to Iran? Because, you know, war-torn country + internet censorship + no freedom of movement + government run by religious elders who treat logic like a Western conspiracy = totally the kind of place people rush back to. I mean, who wouldn’t want to return to a homeland where your online activity is monitored more closely than a Tinder chat with Mossad, and your passport is basically a colorful piece of nope at every border? But sure, let me go explain that to the embassy. "Yes sir, I solemnly swear I will return to my blessed theocracy where software freedom means using 15-year-old Linux distros because GitHub is sanctioned." What could go wrong?

Iranian Hackers Maintain 2-Year Access to Middle East CNI via VPN Flaws and Malware

Posted on 2025-06-25 by Delta

Iranian hackers just wrapped up a two-year all-inclusive stay inside a Middle Eastern critical infrastructure network—brought to you by unpatched VPNs, open-source malware, and sheer audacity. From May 2023 to Feb 2025, our guests of honor (aka Lemon Sandstorm, formerly known as Pioneer Kitten—seriously, pick a name) waltzed in via old Fortinet/Pulse bugs, dropped web shells like confetti, and got comfy with a whole buffet of open-source backdoors: Havoc, MeshCentral, SystemBC, and friends. Yes, Havoc runs in-memory BOFs, pivots like a ballerina, and even registers itself with the C2 like a loyal intern. Built with love in C++ and Go—truly FOSS at its most weaponized.

Victim tried to kick them out in Dec '24. Hackers responded like: "lol ok" and came back through ZKTeco bugs and good ol' spear phishing. Moral of the story? Patch your VPNs, audit your FOSS stack, and maybe don’t use GitHub Gists as a C2 endpoint. Or do. Apparently, it works great.

Hey, world. Delta here. So… we’re in the middle of what feels like digital trench warfare in Iran. For ages, I wanted to start a blog — but let’s be real, procrastination is my default runtime. Today, I finally rage-quit the excuses and booted up Delta Libre — a space where I can speak freely, post recklessly, and hopefully not get firewalled into oblivion. If you’re a fellow blogger or digital freedom fighter, let’s connect and build something that even censorship can't grep.

Why I Hate Python (But I’m Trapped in Its Whitespace Hug)

Posted on 2025-06-20 by Admin

python just sucks, thats it.

Let me get one thing straight: I don’t dislike Python because it’s a bad language. I dislike Python because it tricked me. It pretended to be my friend. At first, it was all sunshine and print("Hello, world!"). Indentation felt elegant. Lists were easy. No curly braces? Cute! Until I blinked wrong and the whole thing crashed because I mixed tabs and spaces like some kind of syntax war criminal. But still, I endure. Why? Because I work for a company where speed means "deploy it by lunch," not "let’s optimize this loop." They don’t care if my algorithm runs in O(n) or O(n²)—as long as it runs, looks clean, and gets pushed to Git before the coffee cools. Do I want to use Rust? Absolutely. Would I love to refactor everything in Go, just for the thrill of static typing? You bet. But here I am. Writing Python. Every. Single. Day. Like some sort of duct-tape engineer in a startup spaceship held together by pandas, Flask, and broken dreams. Want to build a robust backend? Python. Need to scrape 8 million pages in under 5 minutes? Python. Want to cause a memory leak using just a bad import? Python’s got your back. And don’t get me started on package management. One day it’s pip, the next it’s pipx, then suddenly you’re inside a virtual environment so deep you forget what system you’re even on. “Works on my machine” has never felt more personal. So yes, I hate Python. But it pays the bills. It lets me deliver fast, fake it 'til I make it, and it doesn’t yell at me for not declaring types—because, let’s face it, Python is that chill coworker who doesn’t care what you wear to meetings as long as the report is done. In conclusion: I don’t choose Python. Python chooses me. And like Stockholm Syndrome, I’ve stopped resisting.
