So gpt-4o is apparently inherently multi modal. From what I understand if you talk to it, it knows the tone of your voice, it doesn’t have to convert text to speech. Same with output. It’s multi modal. Inputs and outputs can start becoming things like text, image, biometric data, other data, video, probably other things overtime.
So is it now a large multimodal model? LMM?

Hello Hive Mind!
I come before you because I am plagued by a dilemma!
My setup consists of a Moog GM, a Hydra Explorer and a small modular rig (mostly rigged with effects and sound mangling modules, a sampler and some utilities). I am looking for one more piece of gear that will tie everything together, become the brain of the setup and also perform drum machine duties.
I don't have a traditional sequencer in my setup (although the GM has a basic sequencer and I also have a Melodicer) nor any dedicated drums (though there are ways to get percussion out of my modular and the Hydra, but alas, sacrificing them in the process). I also find it difficult to transition between parts without a master brain controlling everything.
I dabble mostly in experimental-freeform-ambient-noise (hey don't judge, not everyone has to like techno or IDM...) but I do want some percussion to work as an anchor and offer some rhythmic context. I find it makes stuff more "digestible" for the average listener. It's also nice to have a master brain to mix stuff in, vary the sequences etc.
SO! I have narrowed down my selection to the MPC One and the Octatrack. Both have their cons and their pros.
The MPC One is easier to grasp, is cheaper, has 4 pairs of CV/Gate outputs. On the other hand you spend most of the time fiddling with the touch screen and can only record incoming audio tied to 4/8/16 bars (as far as I know) and is mostly suited for use in beat heavy genres (hip hop, techno etc).
The Octatrack has a more powerful sequencer, an extra set of outputs and inputs and the scenes transition which is extremely cool. On the other hand, it's 13 years old, waaaay past its prime. The workflow is outdated, the UI is archaic, the RAM is just too little, also cannot record more than 80MB of incoming audio (and that's if you have 0 other samples loaded). Also, I am certain that when I purchase it, Elektron will release the Octatrack II or mk3 or whatever, sending it to Valhalla.
So the sensible option would be to get an MPC One right? It has the CV/Gate outputs ready without the need for a MIDI-CV module, it's much more modern and future proof, but there is something about the Octatrack that inspires and commands reverence. Reading the manual I'm like, "oh hey, that's cool, oh hey, this is cool too, wow it can do this too?"

Looking forward to your input.

I like to reduce the transactions sizes by separating my wallet into groups by usage, so that i on't have to toch token-holding utxos while only sending ada. A lot of dApp txbuilders do like to consolidate your utxos into a huge one holding all your ada and tokens. Especially those coming from ergo ecosystem, where the have utxo storage rent, to minimize it. Though just thinking about it, a tx that only takes ada from a token-holding utxo shouldn't need to include any information about the tokens in the tx. Don't you only have to reference and sign the input utxos? Their content are alraeady known from the previous transation that created them, and if all the tokens go back to change, the coins going to change address can be deterministically computed as "sum(inputs) - sum(recipient outputs) - fee".
If the txdata was only stored minimalistically excluding all this redundant information that the syncing nodes already know or can compute, it would reduce tx sizes and fees, and the blockchain bloat, and allow a bit higher TPS. And it would make those utxo consolidations make sense and make them more optimized than grouped utxos.

I am trying to train a machine learning model which can take books as input and do preprocessing but when i tried i found that data preprocessing has been to only csv files, now i want to train a machine learning model which can take pdf files or books as an input and then read them and understand what is inside and then whatever question i ask it should be able to build.
Any idea or guide-way or something will be helpful

Hey everyone, hoping someone can help me with some issues I'm having with my new camera.
I recently bought a Reolink Duo 2 for the price and field of view but I'm having a lot of difficulties integrating this into my setup.
The Reolink duo cameras use H.265 due to the resolution of the camera and I've read this shouldn't be an issue as long as this is restreamed but I'm having difficulties.
At the moment, the camera is in Frigate and I can view the live feed using jsmpeg but mse just loads a blank video window.
I can also see previews of events but events themselves don't load with the following error `Playback cannot continue. No available working or supported playlists`
I am running Frigate in docker with the 7100U iGPU enabled with:

devices: - /dev/dri/renderD128 

my config is as follows:

logger: default: info database: path: /db/frigate.db detectors: coral: type: edgetpu device: pci objects: track: - person - dog - laptop - cell phone - bird - cat - horse ffmpeg: hwaccel_args: - -hwaccel - vaapi - -hwaccel_device - /dev/dri/renderD128 - -hwaccel_output_format - yuv420p go2rtc: streams: camera_duo: - rtsp://frigate:REDACTED@10.99.0.200:554/h264Preview_01_main - "ffmpeg:camera_duo#video=h264#audio=opus#hardware" camera_duo_sub: - "ffmpeg:rtsp://frigate:REDACTED@10.99.0.200:554/h264Preview_01_sub#video=h264#hardware" camera_right: - rtsp://frigate:REDACTED@10.99.0.205:554/stream1 live: height: 1080 quality: 1 record: enabled: true expire_interval: 60 retain: days: 3 mode: motion events: pre_capture: 5 post_capture: 5 retain: default: 14 mode: active_objects # objects: # person: 3 # dog: 7 snapshots: enabled: True timestamp: False bounding_box: True crop: False required_zones: [] retain: default: 31 # objects: # person: 15 detect: width: 2560 height: 1920 fps: 5 enabled: True max_disappeared: 25 stationary: interval: 10 threshold: 50 max_frames: default: 3000 objects: person: 1000 cameras: camera_duo: ffmpeg: output_args: record: preset-record-generic-audio-copy inputs: - path: rtsp://127.0.0.1:8554/camera_duo?video=copy input_args: preset-rtsp-generic roles: - record - path: rtsp://127.0.0.1:8554/camera_duo_sub?video=copy input_args: preset-rtsp-generic roles: - detect detect: enabled: true width: 4608 height: 1728 fps: 5 camera_right: ffmpeg: output_args: record: preset-record-generic inputs: - path: rtsp://127.0.0.1:8554/camera_right?video=copy input_args: preset-rtsp-restream roles: - record - detect 

From what I've read, these ffmpeg settings should be restreaming into H.264 and so everything in browser should be fine, but that doesn't seem to be the case. I'm sure I've missed something so a fresh set of eyes would be great.
Also, I'm not 100% sure the `hwaccel_args` are correct here, but changing anything breaks frigate in my setup and intel_gpu_top does show usage so I've just left it as is for now.
Any help with this greatly appreciated!

Is there a tool which lets users compare outputs from multiple LLM's based off a single prompt? I imagine with LangChain someone can build this locally but wonder if any such products are out there?

So I noticed this today, but can't find many references to anyone else reporting this. I'm not sure if that's because no-one really uses the feature, or if I'm doing something wrong.
When using the h264_videotoolbox or hevc_videotoolbox codecs, the -b:v bitrates are ignored. For example, I encoded a file with -b:v 10000k then -b:v 20000k, yet both times it came out at ~38mbit!
Repeating the encodes with the regular libx264 or libx265 codecs results in the expected bitrates and filesizes.
Is this a known issue? An unknown issue? Am I holding it wrong?
Example command-lines:

ffmpeg -i "$input" -s 4096x2048 -c:v h264_videotoolbox -profile:v high -movflags "+faststart" -b:v 10000k -c:a aac -b:a 160k "$output/video_10MB.mp4" ffmpeg -i "$input" -s 4096x2048 -c:v hevc_videotoolbox -movflags "+faststart" -tag:v "hvc1" -b:v 20000k -c:a aac -b:a 192k "$output/video_hevc_20MB.mp4"

Im M28 and my partner is F27. We’ve been living together for 5 plus years now in an apartment. Recently, I think she gaslighted me - it’s a sunday, I woke up late as I streamed and played a game late the night before.
She woke me up as she cooked eggs and as I was eating, she already finished eating then told me to get up and get the clothes outside. Im fine with it initially as I asked her if I can just finish my eating then I’ll do that. To my shock, she said it cant wait and it’ll be quick. I was asking her if she was joking and as she was leaving to the room she said she wasn’t and closed the door.
I stood up, stopped eating, and followed her to the room asking if she really was joking because I’m still eating and she said she wasn’t. She knows this would frustrate me and I was disappointed and frustrated already I told her why it cant wait as Im still eating, I was asking her what’s with the rush and stuff but she just ignored me and opened her laptop to watch netflix. She ignored me and I was really frustrated. I stopped eating completely, got the hanging clothes outside (which is shaded by the way), I even hanged the newly washed clothes from the washing machine and washed the dishes as well.
We are ignoring each other for about a week now. I still do my normal routing including my solo walks every afternoon and lately it’s been giving me clarity and a moment to think if this relationship is worth it. Of course, this is not the first instance that this happened and recently I just got laid off from my work and it’s too much stress for me to handle. She knows that it takes a lot for me to get through my family problems, recent career problems, Im also not getting younger and the future worries me as I still can’t buy a house or be financially stable to provide for my future family. There are also other instances where she knows it will get me mad and frustrated so she does it or says it. There are also instances where she told me something but when I confirm it with her, she denies it when I really remember that she said it. Another instance which might seem like a little basic is when she gets cold water from the fridge and she returns the glass of water empty or only halfed - I told her to always refill it so we can drink cold water since we dont have a water dispenser and only relies on putting water in the fridge to make it cold. Whenever I ask her why the bottle is empty or halfed, she always denies its her and it’s obviously just the two of us in our apartment.
Another example is she has been asking me if she can loan money from me to buy an ipad but I told her I don’t have much savings and Im planning to go abroad so we have to save as much as we can as were both not from wealthy families, she also has a laptop and an android tablet and whenever I ask her what she will use it for she says just for watching movies and it’s apple - she keeps on repeating this and I always ask her why she can’t but it herself as we’re both working but then she always says she’s just joking but then when she constantly repeats it. I also referred her to my work (which I recently got laid off) even though she has no tech background and she got the job. I thought this could help her buy her mac/ipad. Recently, she bought a macbook thru her colleague’s credit card (she would pay her coworker for 2 months) - she could use this for both work and watching netflix.
I’m not perfect but I keep on telling her I just need peace of mind and for us not to fight and I can continue to fight life and get my stuff together but she is not helping. I have been also waiting for her to initiate and apologize but she appears to be okay even singing (We stay in one room). It’s like she does that care.
Since I’m working from home, I recently tried to work in cafes to get a different environment and think more and she has not sent me a single message to apologize or anything. Her work is only a 3 minute walk from our apartment.
NSFW: Don’t know if this helps but our sexual relationship is pretty normal I think, we have sex like twice or thrice a week (more frequent maybe 3 times or more a week when she’s safe) and just 2 weeks ago she was safe and we just had sex and she says it’s amazing but most of the time I finish before her (about 15 minutes or less I think - she has a nice body I really can’t help it). Last month she also opened up about wanting a sex toy (dildo) and I bought her that and she asks me if I like it when she uses it when we’re making love and I say yeah. Our most recent sex, she made me go outside the room for a couple of minutes then when I went inside she was using the dildo and I made her orgasm with the dildo while licking her clit. Then we do the usual sex without the toy. I noticed however that she denies having orgasm from the toy when I literally see it then she wants the toy removed and she wants my d inserted the .
Tldr: Is my girlfriend gaslighting me? She doesn’t respect my time of eating and she also has been ignoring me and does not appear to care for the past week.
Thanks in advance for thoughts/inputs. Would like to apologize for any grammatical errors if any - Im kind of winging everything right now.

hi guys, i'm relatively new in the world of cameras. i now have a dslr, more precisely a Nikon D3400, but i find it a bit too complicated for live streaming. the autofocus is a bit trash and even if i get clean hdmi output i don't like the quality. so i want to switch to a mirrorless because it is easier to use. i want to buy a used one, my budget is around 250 euros total for the body and the lenses.
i had the opportunity to work with a sony a6000 and i think this might be the best option for me. there is clean hdmi, even if there isn't the input for an external microphone, the integrated one is good enough for me. it records 1080p at 24/30/60 fps and it's good because i want to use also as a vlog camera. there is also the viewfinder if i want to use as a normal camera when i don't stream. the screen doesn't tilt by 180 degrees but in the end i don't care too much. the autofocus works flawlessly and it also shoots raw photos, so this is the best options. but it has a few drawbacks, the price is too high, on ebay and wallapop is around 300 euros, so even if it is the best option i can't afford it.
so now the options is the sony a5100, the lenses are the same to the a6000 (and this is good, because these lenses are pretty cheap), i didn't test it but after looking on internet i can assume there is hdmi output, it also records 1080p at 24/30/60 fps and it's okay. in this the screen tilts 180 degrees, which is good but as i said before i don't care too much about it. also the a5000 shoots raw, but now we arrives at the drawbacks. there isn't the viewfinder for shooting photos, and i don't trust the lcd screen that much in sunny days. it lacks the hot shoe for attaching flashes and external microphones, because the camera doesn't have the mic input.
then i watched the sony aplha nex-5, the price was pretty good, but unfortunatelly i had to exclude it because it hasn't clean hdmi output.
so, now i want to know your opinion about this. advice on other models are appreciated. thank you in advance
(sorry for my bad english🙃)

To no avail. MS official documentation says only AD environments are supported, but has anyone found any workarounds? I hate bing and I also want to have to do as little as possible manual labor when deploying new images on my home systems.
I've pretty much scripted out everything but this. And I hate bing.
Same for cookies, to no avail
Same thing applies to the cookies script I have written. I can't see anything wrong with it.

I'm referring to the Tokens Per Minute and Tokens Per Day numbers here.
I think that this counts both input and output tokens, but wanted to check.

I'm sure most of you know OpenAI just announced GPT-4o, a new model that can reason across audio, vision, and text in real time (See OpenAI's demo on YouTube)
By chance, I've been working with multimodal models far before GPT-4o's release, so I feel well-positioned to leave a guide here for anyone looking to build something with it!
Recently, I released an open source library so you can extract data in multiple modalities to feed your AI-based Python projects. In this post, I'll show you how to use it alongside GPT-4o with the OpenAI API to build multimodal apps with it. I've got nothing better to do right now, so I'll walk through the steps of extracting all multimodal content from different sources, preparing the input for GPT-4o, sending it to the model for processing, and getting our results back.
before getting into the code, let's just stop and ask ourselves why we'd use GPT-4o over previous models like GPT-4-turbo:
Multi-modal Input and Output: GPT-4o can handle text, audio, and image inputs and generate outputs in any of these formats.
Real-time Processing: The model can respond to audio inputs in as little as 232 milliseconds, making it suitable for real-time applications.
Improved Performance: GPT-4o matches GPT-4 Turbo performance on text in English and code, with significant improvements in non-English languages, vision, and audio understanding.
Cost and Speed: GPT-4o is 50% cheaper and 2x faster than GPT-4 Turbo, with 5x higher rate limits.
Ok, let's get to the code lol:

Step 1: Extract!

This can be done using The Pipe API which can handle various file types and URLs, extracting text and images in a format that GPT-4o can understand.
For example, if we were analyzing a talk based on a scientific paper, we could combine the two sources to provide a comprehensive input to GPT-4o:

from thepipe_api import thepipe # Extract multimodal content from a PDF pdf = thepipe.extract("path/to/paper.pdf") # Extract multimodal content from a YouTube video vid = thepipe.extract("https://youtu.be/dQw4w9WgXcQ") 

Step 2: Prepare the Input for GPT-4o

Here's an example of how to prepare the input prompt by simply combining the extracted content with a question from the user:

# Add a user query query = [{ "role": "user", "content": "Which figures from the paper would help answer the question at the end of the talk video?" }] # Combine the content to create the input prompt for GPT-4o messages = pdf + vid + query 

Step 3: Send the Input to GPT-4o

With the input prepared, you can now send it to GPT-4o using the OpenAI API. Make sure you have your OPENAI_API_KEY set in your environment variables.

from openai import OpenAI # Initialize the OpenAI client openai_client = OpenAI() # Send the input to GPT-4o response = openai_client.chat.completions.create( model="gpt-4o", messages=messages, ) # Print the response print(response.choices[0].message.content) 

All done!

PS:
If you have literally no idea what I'm talking about, check out the OpenAI GPT-4O announcement!.
If you're a developer, feel free to access or contribute to The Pipe on GitHub! It is important to note that OpenAI's GPT-4o model is only accepting textual and visual modalities at release, however we will be carefully monitoring the new modalities released for GPT-4o in the coming weeks and updating the library accordingly.

Mathematics has often been perceived as an abstract and theoretical discipline, one that deals with numbers, equations, and theorems far removed from the practical concerns of everyday life. However, this perception overlooks the profound impact that mathematics has on various real-world applications. Dr. Dimitrios Psaroudakis, an Associate Professor at the Department of Mathematics at Aristotle University of Thessaloniki, Greece, provides a unique perspective on how mathematics intersects with and enhances real-world applications. With his extensive research and academic contributions, Dr. Dimitrios Psaroudakis GMC illustrates how mathematical concepts are integral to solving complex problems in diverse fields.

The Role of Mathematics in Understanding the Natural World

Mathematics is often described as the language of the universe. It provides a framework through which we can describe, analyze, and predict natural phenomena. Dr. Dimitrios Psaroudakis GMC work at Aristotle University emphasizes the importance of mathematical models in understanding the natural world.

Mathematical Models in Physics and Engineering

In physics, mathematical models are crucial for describing the behavior of physical systems. For example, Newton's laws of motion, expressed through differential equations, allow us to predict the movement of objects under various forces. Similarly, Maxwell's equations describe the behavior of electric and magnetic fields. These equations are not just abstract constructs; they have practical applications in engineering, such as in the design of electrical circuits and communication systems.
Dr Dimitrios Psaroudakis GMC highlights how advanced mathematical techniques, such as partial differential equations and numerical methods, are used to solve complex problems in engineering. These techniques enable engineers to design more efficient structures, optimize manufacturing processes, and develop new materials with specific properties. By providing a rigorous framework for analyzing physical systems, mathematics becomes an indispensable tool in engineering innovation.

Mathematical Biology and Medicine

Mathematics also plays a critical role in the life sciences. Dr Dimitrios Psaroudakis GMC points out that mathematical biology uses models to understand biological processes and systems. For instance, differential equations are used to model the spread of infectious diseases, allowing public health officials to predict and control outbreaks.
