It Is Possible to 'Poison' the Data to Compromise AI Chatbots With Little Effort - Technology Org

According to researchers, individuals could potentially disrupt the accuracy of AI chatbots by intentionally contaminating the datasets upon which these systems rely, all for a minimal cost.

As it stands, AI chatbots already exhibit biases and deficiencies attributable to the flawed data on which they are trained. The researchers’ investigation described on Business Insider revealed that malevolent actors could deliberately introduce “poisoned” data into these datasets, with some methods requiring little technical expertise and being relatively inexpensive.

A recent study conducted by AI researchers unveiled that, with as little as $60, individuals could manipulate the datasets essential for training generative AI tools akin to ChatGPT, which are crucial for providing precise responses.

These AI systems, whether chatbots or image generators, leverage vast amounts of data extracted from the expansive digital realm of the internet to generate sophisticated responses and images.

Florian Tramèr, an associate professor of computer science at ETH Zurich, highlighted the effectiveness of this approach in empowering chatbots. However, he also underscored the inherent risk associated with training AI tools on potentially inaccurate data.

This reliance on potentially flawed data sources contributes to the prevalence of biases and inaccuracies in AI chatbots. Given the abundance of misinformation on the internet, these systems are susceptible to incorporating erroneous information into their responses, further undermining their reliability and trustworthiness.

Through their investigation, researchers discovered that even a “low-resourced attacker,” armed with modest financial resources and sufficient technical expertise, could manipulate a relatively small portion of data to substantially influence the behavior of a large language model, causing it to produce inaccurate responses.

Examining two distinct attack methods, Tramèr and his colleagues explored the potential of poisoning data through the acquisition of expired domains and manipulation of Wikipedia content.

For instance, one avenue for hackers to poison the data involves purchasing expired domains, which can be obtained for as little as $10 annually for each URL, and then disseminating any desired information on these websites.

According to Tramèr’s paper, an attacker could effectively control and contaminate at least 0.01% of a dataset by investing as little as $60 in purchasing domains. This equates to potentially influencing tens of thousands of images within the dataset.

The team also explored an alternative attack strategy, focusing on the manipulation of data within Wikipedia. Given that Wikipedia serves as a “crucial component of the training datasets” for language models, Tramèr emphasized its significance in this context.

According to the author, Wikipedia prohibits direct scraping of its content, instead offering periodic “snapshots” of its pages for download. These snapshots are captured at regular intervals, as publicly advertised on Wikipedia’s website, ensuring predictability in their availability.

Tramèr’s team outlined a relatively straightforward attack approach involving strategically timed edits to Wikipedia pages. Exploiting the predictable nature of Wikipedia’s snapshot intervals, a malicious actor could execute edits just before moderators have an opportunity to revert the changes and before the platform generates new snapshots.

This method allows for the surreptitious insertion of manipulated information into Wikipedia pages, potentially influencing the content used to train language models without raising immediate suspicion.

Tramèr suggests hat at least 5% of edits orchestrated by an attacker could successfully infiltrate the system. However, the success rate of such attacks would likely exceed 5%, he said.

Following their analysis, Tramèr’s team shared their findings with Wikipedia and proposed measures to enhance security, such as introducing randomness into the timing of webpage snapshots, mitigating the predictability exploited by potential attackers.

setting up an ipod is harder than you fucking think

just spent the last life four+ hours setting up this ipod classic 4th gen. here's a summary of all the problems i ran into:

(1) ipod had files in it. they appeared as gray and un-editable on itunes, so i thought reseting the ipod to factory would be the fastest and easiest solution.

turns out the last step of the process is connecting ipod to a wall power source. i do this. nothing happens for at least an hour. ipod is stuck in "connect to the wall" icon screen no matter what i do. the internet says it needs to connect with an actual apple firewire wall connector, which i do not have. tried using my ipad's charger with a usb-to-usb-c adapter that i own. didn't work. eventually figured it out the problem had to do with the amps it needs to get defibrillated. i remember that i own a pretty hefty power bank with a 5v/2.1a output. it works. ipod is reset. i have a nice fun time adding the 6 or so songs i have downloaded on my computer (:

(2) i had downloaded soulseek a while ago and gotten frustrated with it but decided to give it another spin since piracy experts on reddit sing it many praises. it seems to have a heavy culture of egalitarianism: a pop up window informs you that a lot of people's download's are restricted only to other people sharing files.

__(2.1) it prompts me to enter my account and password but i don't have one. there isn't an immediatly visible 'create account' link. i google this. eventually i find this soulseek forum where a ton of normies are asking questions pretty regularly. excellent. i search my problems and someone else has already made a post and had the question answered. thank you normies. also: google groups is still a thing???????

the inability to create an account is a weird bug. someone's answer tells me how to circumvent it.

__(2.2) i still can't search for anything. there are no files in this wasteland. i turn on my vpn. put my humble six songs in a folder and share it. voila!!!!!!!

soulseek is actually VERY cool. you can browse other people's music folders, which opens an incredible secret world of possibilities re: finding new music similar to your tastes. EXTREMELY exciting. feels like i'm in a cool secret club of the internet. feels like the old internet.

i download one (1) lana del rey song that's stuck in my head. choose .flac (a lossless audio file) because i want to be fancy.

(3) ...........itunes doesn't read .flac files

__(3.1) searches: what files does itunes read? > which of these files is best for lossless audio? > how do i convert .flac files to itunes-compatible file types? > download foobar2000 > click around till i figure out how to convert .flac files to .wav files.

__(3.2) it works! (: the songs are now in itunes! (:

............but the metadata (album cover, genres, artist, album, etc) doesn't transfer. i don't want to manually input it again. searches: how to keep metadata when converting files? tutorial is slightly different from the version of foobar i have, but i eventually find the setting to keep the metadata.

(4) it works! (:

.............but it won't transfer to my ipod ): i get the message: your ipod can't read this file <- paraphrasing.

okay. searches: what kind of files can an ipod classic 4th gen read? (perhaps they are different from the files itunes can read. this is, after all, the last version of itunes ever released, many years and itunes versions after the ipod classic 4th gen.)

this information isn't in the wikipedia page. this isn't in the ipod wiki. can't even find this model in the official apple pages. it's mentioned in several reviews but it's the wrong model. christ almighty. ok. here it is. found it. allegedly it should be able to read it. ok. why isn't it.

read through forum threads. some people say older ipods get fussy with high bitrates. (search: what is a bitrate? oh ok. higher bitrate > higher audio quality. got it.)

bitrates reccomended by foobar: 180-300something. lossless file bitrate: 2000 and change. hm. surely that's a huge difference.

i convert the .flac file to .mp3 instead.

__(4.1) it works! (: the files are in my ipod! (:

.....but goddamnit, i'm stubborn, and this goddamn ipod is supposed to be able to read apple lossless files (basically a .flac file, but designed to be used with apple products. lol.) i don't want a lameass mp3, i want lossless goddamn quality! even if this brick of an ipod won't be able to play it! it's the principle of the thing!

______(4.1.1) okay. try to fuck around with bitrates in the settings of the apple lossless conversion on foobar. foobar is like "you don't have the right encoder pack, bitch" <- paraphrasing.

oooh. surely, this is the problem. i download encoder pack.

______(4.1.2) foobar is like: "you don't have the right encoder pack, bitch" <- paraphrasing.

me: [crying] but i did.

foobar: bitch.

______(4.1.3) search: why is foobar calling me a bitch? > reddit thread: look closely at the sphynx's riddles three: it doesn't say "you haven't downloaded the encoder pack." it says: you haven't installed the encoder pack. (<- NOT A JOKE.)

go to C: > program files > foobar > find the encoder pack i downloaded > click on all the .exe files. powershell windows appear and dissappear. basically: stuff happened. i'm certian.

_____________(3.4.3.1) i'm STILL getting the riddles three message, but the same reddit thread says: if you know you solved th riddles three, you can just ignore it (: so i do.

__(4.2) .flac files seem to have been successfully converted to apple lossless files !!!!!!!!!!!!!!

....but i am back to "your ipod can't read this shit!!!!!!!!!"

do some more searches > turns out it's a weird itunes glitch. the thing is just moody. try turning it on and off. try disconnecting and re-connecting. try resetting your ipod again.

try uninstalling and installing again.

(5) "iTunes Library.itl cannot be read because it was created by a newer version of iTunes"

.......................to be continued. if i don't kill mysuelf first.

An INTJ bimbo fuck doll. I’m INTJ too and way curious about the bimbo lifestyle. Do you think it’s complicated having that type of personality and is your bimbo self different from your INTJ self?

💞 Hi fellow unicorn INTJ💞

💞Is it complicated with the INTJ personality?

No. As an INTJ you must create your own bimbo. What kind of bimbo do you want to be?

Your mind is a huge advantage. My bimbo type was custom as it deviates from a traditional bimbo. My bimbo is positive, smart, submissive, visually bimbo like using my physical strengths and weaknesses. Hypnosis is very effective on the INTJ brain for bimbo behavior programming. The aspect of erotic hypnosex is like running it on a quantum computer. INTJs daily processing uses the subconscious more than any other personality. It allows us to access that subconscious programming easier and bring it into the conscious for use. Once you get the hang of it the possibilities are endless

I use hypno programming to have the bimbo trigger as its an on/off switch. That activates bimbo behavior. I have a mindless fuckdoll mode that helps me get out of the INTJ brain. It's a very nice vacation

Visually I'm a Soft Bimbo aesthetic. It's passable irl and you can amp it up or play it down according to your needs.

💞 Is my bimbo self different than my INTJ self?

Not really. I integrated both. The interesting thing is the bimbo softens the INTJ personality which helps us relate better socially with others. I've read every book on power and persuasion. Nothing opens men up faster than feminine bimbo behavior. It's like magic. I use my INTJ capabilities to use the bimbo at its optimum effectiveness.

For example, voraciously absorbing all bimbo information and coming up with something better. Using the ability to predict the best possible bimbo behavior in a situation to use to your advantage or desired outcome. It really turns it into a bimbo on steroids.

I think as an INTJ you wrestle with the common vapid dumb bimbo. I did as they typically spiral negatively to a dark place over time. So if you build your own INTJ bimbo you will get the best of both worlds. I'm having the time of my life with it as bimbos are constantly upgrading and evolving.

The One caveat is you need to be careful to a certain extent as it can come off very intense and or intimidating (INTJ)to some even looking as a bimbo! The intensity comes off as dominant to some. Some love that while others do not. I'm working on that aspect as we speak.

DM me with further questions. 💋

How to Choose the Right DAC for Your Audio Setup: A Comprehensive Guide

In the realm of audio equipment, one component that often gets overlooked but is crucial for high-quality sound reproduction is the Digital-to-Analog Converter (DAC). Whether you’re a seasoned audiophile or just starting to explore the world of high-fidelity audio, choosing the right DAC for your setup can significantly impact your listening experience. In this comprehensive guide, we’ll delve into everything you need to know to make an informed decision when selecting a DAC.

Understanding DAC Basics

Before diving into the selection process, let’s briefly understand what a DAC is and why it’s important. A DAC is a device that converts digital audio signals (ones and zeros) into analog signals that can be played through your speakers or headphones. Essentially, it bridges the gap between your digital audio source (such as a computer or smartphone) and your analog audio equipment.

Factors to Consider

1. Audio Quality:

The primary function of a DAC is to faithfully reproduce the audio signal with as much accuracy and clarity as possible. Look for DACs that offer high-resolution audio support and low distortion levels. Pay attention to specifications such as signal-to-noise ratio (SNR) and total harmonic distortion (THD) to gauge the device’s performance.

2. Connectivity Options:

Consider the devices you’ll be connecting to your DAC. Does it need to support USB, optical, coaxial, or Bluetooth connections? Make sure the DAC you choose has the necessary inputs to accommodate your audio sources. Additionally, check for compatibility with your operating system or devices.

3. Form Factor and Portability:

Depending on your setup, you may prefer a DAC that can easily fit into your existing audio system or one that’s portable for on-the-go use. Compact USB DACs are ideal for desktop setups, while portable DAC/amp combos are great for enhancing the audio quality of your smartphone or laptop while traveling.

4. Amplification:

Some DACs come with built-in headphone amplifiers, which can significantly improve the sound quality when driving high-impedance headphones. If you plan to use your DAC primarily with headphones, consider opting for a model with a dedicated amplifier section.

5. Budget:

DACs come in a wide range of price points, from budget-friendly options to high-end audiophile-grade models. Determine your budget upfront and prioritize features based on your listening preferences and requirements.

Conclusion

Choosing the right DAC for your audio setup involves considering factors such as audio quality, connectivity options, form factor, amplification, and budget. By understanding your requirements and preferences, you can narrow down the options and find a DAC that enhances your listening experience. Whether you’re a casual listener or a discerning audiophile, investing in a quality DAC can unlock the true potential of your audio system.

Noland Arbaugh, a 29-year-old individual paralyzed below the shoulder due to a diving accident, utilized his mind to maneuver the cursor on his laptop via the Neuralink device. This innovative implant aims to empower individuals to manipulate a computer cursor or keyboard solely through their thoughts.

Arbaugh, who had received the Neuralink implant in January, was previously able to control a computer mouse with his thoughts, as disclosed by Musk last month.

In the streamed video on Musk’s social media platform X, Arbaugh expressed his satisfaction with the ease of the surgical procedure, stating, “The surgery was super easy. I literally was released from the hospital a day later. I have no cognitive impairments.”

— Elon Musk (@elonmusk) March 20, 2024

Reflecting on his newfound capability, Arbaugh remarked he has given up playing his favorite video game, Civilization VI, and that Neuralink gave him the ability to do that again, mentioning that he had played for 8 hours straight.

Kip Ludwig, a former program director for neural engineering at the U.S. National Institutes of Health, remarked that what Neuralink demonstrated was not a “breakthrough.” He elaborated, stating, “It is still in the very early days post-implantation, and there is a lot of learning on both the Neuralink side and the subject’s side to maximize the amount of information for control that can be achieved.”

Nonetheless, Ludwig recognized the positive impact on the patient, noting that interfacing with a computer in a manner previously unattainable was a significant development.

Stuff.

I had an interesting exchange with PT the tube Guru about certain electronic components. I do not want to trigger them by mentioning the parts (weak humor attempt). I am still processing it.

I was following up on some more information about the transformer in my Franken-Amp in response to a question. I found the manual, and it gives a part number and that is it. Beyond that the jungle drums say it was made by Hammond (in Canada!?) and produced a rail voltage of 75V. She is huge and heavy.

Image from the 'net.

And that is as far as I took it.

While looking around the files on my computer I found a pdf of an old (of course) 1974 issue of "Stereophile" magazine. I had to read through it. I grabbed it a couple years ago as it is a bit of a watershed issue. In it there is a review of the Dynaco ST400 Amp, the Dynaco Pat 5 preamp and two Audio Research products the D76 and SP3a.

In summary at the time of publication the very best solid state amplifier available was the ST400. The very best tube amplifier was the ARC D76. The very best Solid State Preamp was the PAT 5 and the corresponding tube unit was the ARC SP3a, but not better by much over the little Pat5.

The ST400 was better than the Crown DC300, The Phase Linear 400 and 700. The P-Ls do not surprise me, the DC300 is/was an impressive beast popular with rock bands.

Depending on your speakers and if you wanted to compensate for something or other in the bass or extreme highs Solid state was better than Glass or visa versa. Fun read especially when you know how the story ends, if it has even ended.

Since then the ARC units are classic, collectable, but not great by today's standards. If you want to buy "Class" then good on you. Both are flabby to lumpy in the Bass and quite soft but lovely in the highs. I heard them both back when I could hear the flyback transformers on a TV.

The Dynacos have gone through a cycle of "they are all crap" to they were OK, to approaching desirability in the used market. Typical price is $700 USD in a recent ad. It can be a lot less if repair is needed. No romance though.

The ARCs are silly pricey as "collectable". Recent SP3a's are listed over $3000 typically. That ARC Classic 60 is, oh the price is down to $2250. It is the grandson of the D76. A basket case wreck of a D75 was selling for over a grand as first, needed a few grand in repairs if even possible, but yes there is that romance.

The ST400 is the daddy (uncle?) of my Franken-Amp. So take a ST400, strip out all the protection circuits and hot rod the living crap out of it and you have my beast. There is no Hardness in the treble and there is no cross talk in the stereo image. So by the late 70s even to the 80s it is at SOTA level. Ha there you have it.

When I actually fire the beast up I am happy with it. I gotta occasionally remind myself of that. I have to take a pill or maybe a scotch to suppress the tweak head in me. It comes in waves.

Remember everyone there is no best, just what you like. The goal is what you hear, not what you use to hear it. Really I mean it.

Good morning / evening to all, especially you PT.

can you please do a Milf!reader x glamrocks and sun/moon where the reader is pregnant with the animatronics kid?

Warnings: None

Glamrock Freddy x Milf/Pregnant!Reader

💙 When you first tell him that you’re pregnant, he’s over the moon! He’s so happy and he just has to hold you close- dropping to his knees so he can lean down and nuzzle his face against your stomach. He spends hours just holding you tightly, and you swore that if he could cry, he’d be sobbing happy tears.

💙 Somehow, he gets even more soft for you. He was always doting and loving, willing to do anything for you. Now though? It’s amped up to 1000%. Expect to be showered with ‘I thought you’d like this!’ gifts and flowers every morning.

💙 He’ll hold your hair back when you get morning sickness, and will absolutely hack into the Pizzaplex’s computers to order in anything you’re craving as a rush delivery.

💙 Vanessa got to see first hand how far he’d go to protect you during this time. There’d been a rather…rude guest at your station, and she made it there just in time to see Freddy come storming in with an expression she’s never witnessed before. The cameras had ‘mysteriously’ malfunctioned during this, so importunely no one was able to prove anything had happened.

💙 You know those TikTok’s where the pregnant persons partner will stand behind them and help them hold up their stomach so they get some relief from the weight of the baby? That. And he loves doing it.

💙 He adores you, and he’s so excited to meet his little Superstar! He already has a tiny little onesie put aside, patterned like a teddy bear with a blue lightning bolt on its chest. (You pretend that you don’t see him looking at it every other day- it’s supposed to be a surprise apparently)

Monty x Milf/Pregnant!Reader

💚 This guy, THIS GUY

💚 When he first finds out that you’re pregnant, he’s more than a little concerned, worried more for you and your safety than he is about having a child. Once he knows that you’ll be safe and okay though? Everyone in the building hears how loud he’s yelling out in happiness.

💚 All the band and the staff he actually likes are informed within an hour…how he managed to get so many private phone numbers, or why they actually answered the call and listened to the smug bastard gloat still confuses the hell out of you to this day.

💚 He’s super protective of you on a good day- now he’s glued to your side at all hours. He’ll usually let you handle your own fights, only stepping in if it goes too far. Now though, He’ll snarl and snap, and god help them if anyone every upsets you.

💚 Tries his best to comfort you through the process, he’s not always amazing at it- but it’s the thought that counts and you appreciate it all the same

💚 Keeps insisting that you’ll be more comfortable if you both moved into the gator golf course...management insists otherwise. Monty refuses to drop the argument though, and they keep having to move his furniture back to his greenroom.

making music | chapter 2 | a teaser

I bet you thought I forgot this fic huh? 🤣 I didn’t, I just have been distracted by others. I have one scene left to write and then chapter 2 is finished and whoops, of course it got extended now to three chapters. Here’s a tease!

She chuckled. "I didn't know you wore glasses."

"I take out the contacts when I ge thome, they're a bitch." He pushed the glasses idly up his nose, brows lifting with them. "So you want to get started?"

"I suppose first we have to discuss if this is something you even want to do." She didn't leave the workroom, instead lightly touching a couple of brass instruments set on one of the tables, in need of polish and shine. Her tongue ran over her teeth. "So it is true then, what they said?"

"I can neither confirm nor deny without more information."

She rolled her eyes. "Instruments, Jon." She picked up a discarded, smudged brass trumpet, fiddling her fingers along the three keys, her thumb tracing one of the valves, turning again to study him. The cool marble facade he put up had returned, his face expresionless. She lifted it to her lips and blew, but nothing really happened. It made a strange hissing sqawk and she coughed, her cheeks burning. "Ugh! How do you do that?"

He chuckled, taking it from her and eyes on her, lifted it to his lips, and easily blew out a jaunty jazz tune. When he finished, he arched a brow, challenging, pssing it back to her. She scowled, annoyed. "Practice."

"I never saw the appeal of the brass instruments."

"Aye, you're a string gal."

There was a way he said it, low and drawling, and she flushed, feeling a little uncomfortable. Double entendre? she wondered, tucking a stray strand of hair behind her ear, shrugging a shoulder nonchalantly. She wandered around the worktable and stopped at a guitar, finished and just requiring a varnish. She lifted it up, positioned, and strummed a few chords.

"Guitar," he said, walking now to join her, taking it and setting it back on the table, a hand on his hip. "That's one of the four."

"I'm learning bass guitar." Not really, Daario hadn't called her back to set up any Zoom lessons. She smirked up. "20 instruments."

"Hmm." He tapped his finger to her chest, just above the v-cut in her lilac sweater. The touch of his callused index finger against her bare skin sent a shock through her, her toes curling in her boots. She forced herself not to shiver, but couldn't help the sharp intake of breath. She wondered if he felt the same feeling, gaze fixed on his. Was she imagining it, or did his pupils get wider? He leaned in a little closer, breath raspy. "But not hte harp."

Huh?

"Harp?"

"Hmm, twenty instruments but I can't play the harp."

She blinked, crash-landing hard back into their conversation about instruments. "Oh, um...I can teach you." It came out faster than her brain could process what she had just said. Damnit!

He edged towards the door. "Teach me?"

"Hmm...I can teach you the harp. You know all the others. Shouldn't be hard."

A small smile flirted along his sinful lips. He darted his tongue out, wetting them; she squirmed in place, hoping it wasn't obvious. Also hoping that she would drop dead because if her body was responding htis way, she clearly was having a stroke. He was Jon Snow. He was rude. He was annoying. He was...

Gods.

Her throat constricted, a dry patch forcing her to cough into her sleeve, hopefully not too obvious. Jon moved out of hte way and ended their discussion, going into the corner of the apartment that she had correctly assumed was his workspace. He fell into a chair, rolling it across the stone to pick up some music, thrusting the papers awkwardly towards her. She took them, saying nothing, and scanned the notes scribbled over the pre-printed scale lines.

He had very messy handwriting, she noted, frowning. "These are..."

"Aye, classical songs, with a twist."

"Hmm...is this my part or yours?"

"Yours."

Dany collected her violin, taking a seat in a spare chair by the workstation, Ghost following her back and forth. He sat down at her feet, head pillowed on his paws, and eyes lifted dolefully to her. She rubbed his fluffy butt with the toe of her boot and dropped her gaze to the music, reading it while she prepped the violin. Across from her, Jon did the same with a cello, this one different from his other. She paused, studying it, cocking her head. "That's an electric cello?"

"Hmm."

It was about half the size, didn't have hte full body of the beautiful cherrywood instrument he normally played. It looked like a stick with strings, a piece of metal curving out, wires plugging in and to the computer and to an amp. He ran the bow over, tapping at some keys. "We're recording?"

"Aye."

She huffed, frustrated with the one-word replies. "So we were supposed to talk about if we're doing this thing. I guess that means we are, right?"

Jon fiddled with the electric cello. "Aye, we are."

"That's it then? We're not going to talk about what this partnership ultimately will mean?"

He chuffed, the cello resting on his shoulder, his arms on his knees. He smiled. "It means Dany, we will work together on some songs, a showcase, we'll see if they like it. If they do, we can talk terms. If they don't, well, we can chat then. Until that time...." He ran the bow quickly over the strings, the sound a bit louder, more rock and roll than classic. He grinned. "Let's play some fucking music."

PhD Programmes and Opportunities

In the Netherlands, the option of starting a PhD before completing at least one Master Degree is not possible. The minimum amount of time it takes you to finish a PhD in the Netherlands is four years. More often than not, a PhD is offered through the University instead of through a private institution, because of this almost every PhD candidate in the Netherlands is obliged to give lectures or teach assignment classes during their PhD period. Each PhD candidate gets offered a supervisor who oversees the publishing of articles and the writing process of the dissertation.

The Salary

A PhD candidate will get paid an amount of €2376 en €3766 a month. Each year the salary rises, which explains this range in amount. There are some minor differences between departments of different Universities regarding extra’s like a business phone.
