Best Data Modeling Tools: Which One is Right for Data Analysis?

Data modeling is a crucial aspect of data analysis, as it lays the foundation for organizing, managing, and utilizing data effectively. The right data modeling tool can streamline this process, making it easier to design and manage databases, understand relationships between data, and ultimately drive insights. With numerous data modeling tools available, choosing the right one can be challenging. This article will explore some of the best data modeling tools and help you determine which one is right for your data analysis needs.

What is Data Modeling?

Data modeling is the process of creating a visual representation of a system or database. It involves defining the structure of data, relationships, constraints, and more. Data modeling helps organizations to understand their data better, leading to more informed decision-making. It’s a critical step in database design, ensuring that data is stored efficiently and can be retrieved easily when needed.

Why is Data Modeling Important?

Data modeling plays a vital role in the accuracy and efficiency of data analysis. It helps in:

Understanding Data Relationships: Modeling reveals how different data elements interact with each other.

"Weeks after The New York Times updated its terms of service (TOS) to prohibit AI companies from scraping its articles and images to train AI models, it appears that the Times may be preparing to sue OpenAI. The result, experts speculate, could be devastating to OpenAI, including the destruction of ChatGPT's dataset and fines up to $150,000 per infringing piece of content.

NPR spoke to two people "with direct knowledge" who confirmed that the Times' lawyers were mulling whether a lawsuit might be necessary "to protect the intellectual property rights" of the Times' reporting.

Neither OpenAI nor the Times immediately responded to Ars' request to comment.

If the Times were to follow through and sue ChatGPT-maker OpenAI, NPR suggested that the lawsuit could become "the most high-profile" legal battle yet over copyright protection since ChatGPT's explosively popular launch. This speculation comes a month after Sarah Silverman joined other popular authors suing OpenAI over similar concerns, seeking to protect the copyright of their books.

Of course, ChatGPT isn't the only generative AI tool drawing legal challenges over copyright claims. In April, experts told Ars that image-generator Stable Diffusion could be a "legal earthquake" due to copyright concerns.

But OpenAI seems to be a prime target for early lawsuits, and NPR reported that OpenAI risks a federal judge ordering ChatGPT's entire data set to be completely rebuilt—if the Times successfully proves the company copied its content illegally and the court restricts OpenAI training models to only include explicitly authorized data. OpenAI could face huge fines for each piece of infringing content, dealing OpenAI a massive financial blow just months after The Washington Post reported that ChatGPT has begun shedding users, "shaking faith in AI revolution." Beyond that, a legal victory could trigger an avalanche of similar claims from other rights holders.

Unlike authors who appear most concerned about retaining the option to remove their books from OpenAI's training models, the Times has other concerns about AI tools like ChatGPT. NPR reported that a "top concern" is that ChatGPT could use The Times' content to become a "competitor" by "creating text that answers questions based on the original reporting and writing of the paper's staff."

As of this month, the Times' TOS prohibits any use of its content for "the development of any software program, including, but not limited to, training a machine learning or artificial intelligence (AI) system.""

Info from the associated blogpost:

"Mass Effect Miniatures By Gavin Dady Art by David Benzal October sees the launch of Mass Effect The Boardgame - Priority: Hagalaz. In it, Commander Shepard and their band of loyal squadmates take on a new mission to explore a crashed Cerberus Cruiser on the storm-wracked world of Hagalaz. Within the cruiser they will face many dangerous enemies, from the survivors of the Cerberus crew, native life and even the dangerous captives and experiments that Cerberus were keeping aboard the ship. The enemies are represented by thick, full colour, illustrated card tokens in the game, but Modiphius are also producing a range of 32mm, multipart miniatures to compliment them. As with our previous Fallout and The Elder Scrolls miniatures, these are highly detailed resin collectors miniatures.    In this first phase of miniatures, we are concentrating on the core sets required to build up the forces for the board game. The first of these is The Heroes of the Normandy Alpha. It includes six miniatures in alternative poses for the PVC sculpts from the board game.  Commander Shepard is represented in both male and female versions. Armed with the M-8 Assault Rifle or her M-3 pistol and Omni-blade, Shepard is ready to take the fight to their enemies. Shepard also comes with optional parts to depict them with either bare head or their iconic helmet from their N7 armour. The former C-Sec officer, Garrus Vakarian, has been by Shepard’s side from their earliest days as a SPECTRE and is depicted in his role as one of the galaxy’s premier snipers (arguments about who is the better shot between Shepard and Garrus aside). Garrus is depicted with his signature M-92 Mantis rifle, repaired armour and the scars he gained as The Archangel. Next amongst Shepard’s staunch allies is Dr. Liara T’soni. A powerful Asari biotic, expert on the ancient Prothean race and, secretly, the powerful underworld figure The Shadowbroker. Liara  is depicted initiating one of her powerful biotic abilities, energy crackling around her hand. Tali’Zhora Nar Rayya is the young Quarian that Shepard first met whilst pursuing the rogue SPECTRE Saren. Tali is a gifted engineer and staunch advocate for the Quarian people. She is depicted with her drone, Chatika, who can be modelled attached to Tali’s Omni-tool, or kept separate to act as a marker during gameplay. Rounding out the squad is Urdnot Wrex, the veteran mercenary and leader of Clan Urdnot. Wrex is a powerhouse in battle, utilising biotic abilities, a powerful M-300 Claymore shotgun and, more than once, a well placed head-butt. As well as these miniatures, we are also producing further sets to compliment the boardgame, including Reaper Forces, Cerberus Troops and some of the Priority Threats that you will face as you make your way through the crashed cruiser. These sets are ideal for upgrading the tokens in the base game, or for use in any miniatures skirmish game (like Five Parsecs from Home) or for miniatures collectors everywhere. Look out for special collectors and gameplay bundles available exclusively from Modiphius  when the Mass Effect Board Game pre-orders go live soon! In the meantime, you can sign-up for more Mass Effect news here."

The tenth Doctor in journeys end (i think?) said a TARDIS is made to be piloted by 6 timelords, what roles would each have in the TARDIS?

What roles would six Time Lords have in piloting a TARDIS?

This is more speculative, based on the known features of a TARDIS.

Console Panels and Systems

A TARDIS console is split into six 'panels', with each panel operating a different aspect of the TARDIS' systems. When there are six pilots, each Time Lord would likely specialise in operating a specific panel and system. Although the console layout may change with each TARDIS's 'desktop theme,' the six fundamental panels remain the same.

[Image ID: On the left is a top-down diagram of the 9th and 10th Doctor's coral theme TARDIS, divided into six panel sections. Each section is labelled from 1-6 clockwise starting from the 12 o'clock position. On the right is a text list of the panels and their names: Panel 1: Mechanical and Master Control, Panel 2: Diagnostic and Internal Ship Systems, Panel 3: Fabrication and Information Systems, Panel 4: Navigation, Panel 5: Helm and Dematerialisation Systems, Panel 6: Communications and Exterior Monitor./.End ID]

See this page on the TARDIS Technical Index for more variations on desktop themes.

👨‍✈️ Roles and Responsibilities

Here's a breakdown of each potential role and their responsibilities:

🔧 Panel 1: Mechanical and Master Control

Role: Chief Engineer

Responsibilities: The chief engineer monitors the TARDIS's overall operation. They ensure that all the mechanical systems and master controls are working properly. If anything goes wrong, they step in and fix it.

🛠️ Panel 2: Diagnostic and Internal Ship Systems

Role: Systems Analyst

Responsibilities: This person is all about the internals. They monitor life support, environmental controls, and the internal power grid. Basically, they make sure everything inside the TARDIS is working as it should.

🖥️ Panel 3: Fabrication and Information Systems

Role: Data Specialist

Responsibilities: Managing the TARDIS’s databases and info systems, and handling any fabrication needs. Whether it’s creating new tools, repairing old ones, or just making sure the information systems are up-to-date, they’ve got it covered.

🧭 Panel 4: Navigation

Role: Navigator

Responsibilities: Plotting courses through time and space. The Navigator makes sure the TARDIS lands where it’s supposed to, calculating all those tricky temporal vectors and spatial positions. They work closely with the Pilot to make sure the journey is smooth and safe.

🚀 Panel 5: Helm and Dematerialisation Systems

Role: Pilot

Responsibilities: This is the person at the helm, controlling take-off, landing, and in-flight manoeuvres. They handle the dematerialisation and rematerialisation of the TARDIS, making sure it takes off and lands without a hitch.

📡 Panel 6: Communications and Exterior Monitor

Role: Communications Officer

Responsibilities: They handle all external communications and keep an eye on what’s going on outside, involving sending or receiving messages or watching out for any threats or anomalies.

🏫 So...

Potentially, each Time Lord on the TARDIS would have a specialised role associated with a specific panel. Ideally, they're probably all working together like a well-oiled machine. However, poor old solo pilots have to jump around like madmen trying to cover all the controls at once.

PSA- Don’t Buy Tesla’s

“She told NBC6 that her husband would be still alive if the Model S door handles simply opened the car. That did not happen in Jutha’s Model Y, because its doors work with electronic actuators. If an electrical failure occurs, they demand a mechanical manual release.”

“Tesla has transitioned to an electromechanical door latch system on its vehicles, which means the doors are not physically connected to the door opening handles. Instead, these are electrical switches that trigger the electric door release system to open the door. Because there is no physical connection between the door handles and the door latching mechanism, it doesn’t work when the 12-volt electrical system is down for some reason.

This usually happens in the case of a crash. At least two car crashes ended with fatalities because people got trapped inside a Tesla.”

“‘Uggh, it's a Tesla. We can't get in these cars,’ one firefighter reportedly said. Despite the difficulty, they acted swiftly, using an ax to smash a window and rescue the child.”

“The Hyundai Venue compact SUV topped iSeeCars’ review of National Highway Traffic Safety Administration Fatality Analysis Reporting System data for most dangerous cars, while Tesla topped its list of most dangerous car brands.”

“These fires burn at much higher temperatures and require a lot more water to fight than conventional car fires. There also isn’t an established consensus on the best firefighting strategies for EVs, experts told Vox.”

Seriously- no matter what your political leanings are- DON’T BUY TESLA’S; the fact that no one is widely discussing a very blatant safety risk that people can’t reliably get out of their cars during a car accident is HORRIBLE…

If you KNOW someone who owns a Tesla- make sure they are AWARE of this flaw in certain vehicles and that they should possibly purchase a window breaker to be safe.

Digimon Data Squad (Savers) - Episode 14

Wow, this episode kinda popped off. I was skeptical at first because there were a lot of wonky/off model shots in the first half, but the fight animation was great! Overall this episode had super snappy pacing and I was on the edge of my seat. Looks like this arc's gonna be good!

Notes:

I can't tell if it's just my imagination, but sometimes it looks like they're using 3DCG for Agumon and Gaomon (outside of digivolution sequences I mean). I keep getting thrown off by how derpy they look. (Maybe it's just how they're shaded?)

It was pretty satisfying when Masaru's mom confirmed that she knew about digimon all along and that's why she wasn't that surprised about Agumon. Brings some perspective/context for earlier episodes and gives this season some rewatch value.

Masaru's dad face reveal! He has his son's curtain bangs lol. Their skin tone is the same too.

We finally see Yoshi at home. Her room is pretty generic. I was kinda hoping they made it a mess as a call back to what Lalamon said about Yoshi being a slob earlier

I find it funny that Sayuri's signature dish is just fried eggs. Finally some achievable mom standards!

Loved the chunky, clunky tools DATS came up with for the journey to the digital world. One of which looks like an 90s cell phone

Love Ikuto. First of all, we haven't really seen this "feral child" concept yet, so he doesn't feel like a rehash of past characters. His design is really strong (kinda reminds me of this obscure manga I used to read called +Anima) and his way of speaking is fun too. I like how he says "humon" in the dub, that's genius. Finally, his fight scene was just really fun to watch.

Can't decide if Peckmon is hilarious or awesome. Either way I got really excited when they revealed him. He's ostrich-sized and kind of like a weird, ninja chocobo. His hair and color scheme is giving me "1980s shounen" vibes. Fascinating.

Sunflowmon continues to be pretty worthless every time 😬

Still hate Jureimon. He's definitely up there in my "top 10 worst digimon designs" list that I store in my brain. At list his Nyokimon were cute.

Was that Gotsumon supposed to be possessed/brainwashed when he was attacking everyone? His eyes got all glowy so I assume that's what they were going for. ~Mysterious~

Jelpax/Drax i(Jeldrax) s the ultimate ship besides Gothrusa.

I wrote a fast SFW fic for the three people that care lol: (warning not beta read I’m sorry, I am lazy and lonely)

Enjoy!

*********

Drax was in shock.

Complete and utter shock.

The keys in his hand were real…*right*?

“Pax…I…” Drax whispered, softly. He felt warm tears for the first time in years well up in his eyes.

“Its rent is covered for a year. I was able to get a good deal and cash a stock or three that my Housefather took out when I began schooling.” Jelpax smiled, holding his gloved hand.

The keys were to an empty old small mechanic shop that had been emptied out. The lights flickered and the paint definitely needed updated but, it was all Drax’s.

“Pax…I don’t even know how to begin to thank you.” Drax sniffled, hugging his handsome coordinator.

“Just promise me you pay the bills and taxes on time alright? If you need help just ask. You know that the High Council has people that do check in on us, okay?” Jelpax asked, glancing out the windows for witnesses before kissing the top Drax’s hat covered head.

“I am going to be a model citizen! You would think I passed Borusa’s advanced civics classes with honors! I think I can make a profit too. I can start spoiling my Jelpax, yes?” Drax smiled.

“Perhaps, but even if you don’t I think it will keep you busy and happier than you working at that awful parts store.” Jelpax explained.

Drax had worked at a local skimmer parts store for nearly 100 years after dropping out from the academy. Jelpax had concern especially when his Drax’s direct deposit would bounce or his expensive personal equipment and tools “missing”. Jelpax had reported the shop dozens of times anonymously through his own government connections, but nothing was ever truly done.

Now Drax could provide services and fill an important niche in the industry by providing regular maintenance and repairs.

The orange light from the setting suns lit the shop in a warm golden glow. Drax once more looked at the keys and smiled. He was going to make Jelpax proud.

*******

“You are letting an academy dropout run his own workshop? That you solely invested in?!” Lord Borusa asked Coordinator Jelpax sternly.

They had met to go over recent happenings in a few quadrants of space that Coordinator Jelpax managed but, like always, conversation on their own personal lives were eventually held over tea and a light snack in Lord Borusa’s office.

“Yes…I did. I know it is not logical sir but, I never felt right seeing Drax go off to work in that shop. He had two bounced paychecks last year alone!” Jelpax explained. Lord Borusa could see the carefully concealed anger brewing beneath Jelpax’s cool and collected demeanor. He, more than anyone, knew how much Drax meant to Jelpax.

“I see. Well. I suppose, as long as he inputs the data correctly, the accounting system will handle things.” Borusa muttered taking another sip of tea; he was wishing deeply that it was wine.

“More importantly, it will keep him busy and out of trouble while I am here helping you and others. My portfolio is very good, Sir. I took the economics classes seriously. He can lose quite a lot before I will shut it down. It is cheaper than funding a lawyer for a felony in street racing.” Jelpax smiled, taking another sip of his own tea.

“‘Fund the passion early so the passion does not become a liability’…that is your argument?”

“Yes, Lord Borusa.”

The Cardinal paused for a moment, reflecting on the current Timelord he shared a bed with off the record.

“Coordinator…you may just be one of the most brilliant in our chapter.” Lord Borusa remarked. Jelpax grinned.

“Thank you, Lord Borusa.”

Beginner Blender Tutorial Basic Render: Part One (Importing a Sim and Adjusting Textures)

To learn the basics, we'll begin with a super simple render: one sim, one pose, one background.

But first, the anatomy of blender.

(image & list courtesy of Blender's online manual)

Yellow - 3D viewport (workspace) The 3D Viewport is used to interact with the 3D scene for a variety of purposes, such as modeling, animating, texture painting, etc.

Green - Outliner The Outliner is a list that organizes data in the blend-file, i.e. the scene data, Video Sequencer data, or anything that gets stored in a blend-file.

Blue - Properties The Properties shows and allows editing of many active data, including the active scene and object.

Red - Timeline The Timeline editor, identified by a clock icon, is used for manipulating keyframes and scrubbing the Playhead.

The tools I use most I've highlighted below:

I won't outline their uses just now, but we'll be going over them as we use them.

Different creators like to split their blender window up in different ways, but this is my preferred setup when I'm working:

I use the yellow half of the screen as a render preview/3D workspace

I use the blue half for shader editing, posing, etc.

You can set yours up like mine or find what's comfortable for you.

When you first open blender, you'll be greeted by the default cube, lamp, and camera.

Delete them! You can do this two ways:

Click and drag your mouse over all 3 and delete or Select all 3 in the side menu and hit x on your keyboard

Step 1: Importing our Sim

After deleting the default items, we'll import our sim. This tutorial assumes you've already ripped your sim (if you haven't, check here for how to do so!)

Now, let's import.

Click file -> import -> collada (dae) Select your DAE and click "import"

Your sim will look a little... off (thick eyelashes and a weird shine), but that's okay we're going to fix it! Your sim might also look solid white. If that's the case, make sure you're in the right mode. You can adjust modes by clicking on one of the four circles in the top right of the screen.

These are your viewport modes.

Wireframe (far left) - good for mesh editing Solid (middle left) - good for posing Material Preview (middle right) - what we work in most, shows everything with textures (color) Rendered (far right) - this shows your render preview We'll be working mostly in Material Preview

You can also switch between modes by hitting z on your keyboard then selecting which one you want I'll be using mostly keyboard shortcuts but I'll show you how to do both as we go along

Step 2: Adjusting Our Sim's Textures

Let's fix our sim's textures.

First. set up your workspace. Separate your workspace into two windows (as shown in the picture above with a yellow half and a blue half) and select "shader editor" in your right-side window. Like this:

Next, navigate to your Outliner and click the little dropdown beside "rig"

Under "rig" you'll see your sim's body parts listed. We're going to select "Body" When we click "Body", these colored blocks will appear in our shader editor window.

These are called Nodes. We use Nodes to adjust textures for various items in blender (sims, walls, furniture, etc). To add a new Node, you can select "add" in the top bar, or hit Shift+A on your keyboard and add in the node you need.

We're going to add in a Mix Shader and a Transparent Shader (both found under the Shader tab) and adjust our nodes this way:

Snug the Mix Shader between the Principled BSDF and the Material Output. Now we have to connect our Nodes and adjust our Principled BSDF. For the sake of this tutorial, I'll show the basic Node & Shader adjustments, but we'll go into each of them in a later tutorial.

Adjust your Principled BSDF like this, then connect your Node lines exactly like this:

You'll see that our SIm's body looks a bit different from her head, hair and shoes. That's good! Now we need to duplicate that texture to the rest of our sim.

Navigate to your Outliner again, and use Shift+Click to select the rest of the body parts in the list Don't select pose or rig.001 and make sure the Body is selected first EDIT: You'll only see "body" if your sim has a full body outfit on! If they have a shirt and pants, you'll have "Bottom" and "Top" instead! In this case, select "bottom"!

Now, hover your cursor over your sim/the 3D viewport window, and press Ctrl+L on your keyboard. This brings up the Link/Transfer data window. Select "Link Materials"

Our sim is looking better, but her eyelashes are still dark, let's fix that now.

In your Properties area, navigate to Material Properties (the little red ball)

Change your Blend Mode to Alpha Hashed We will always set Blend Mode to Alpha Hashed

Now our sim looks right!

In Part Two, we'll pose her, set up the scene, and run the render!

i think also a huge part of why artists majorly refuse machine-learning (bc that’s what it is, i refuse to call it ai bc it’s inaccurate and gives tech bros too much credit) is that the people currently championing and developing those tools actively want it to replace artists. They loudly and proudly hate the arts and want every creative professional put out of work. They want every creative HOBBYIST to give up. I have seen machine-learning art generators call us artoids (like ‘femoids’ incels or unhealthily online misogynists use to refer to women. To give you the idea of the kind of hate-fueled superiority we’re dealing with) and circle-jerk to the idea of art no longer being a career and no one being able to ask for commissions anymore.

Machine-learning tools are currently a symbol of people who see creativity and art as an enemy, a boogeyman to be slain. They are designed accordingly - stealing human work to create the data, designing it so that people can generate ‘sketches’ or ‘doodles’ to deceive the layman that it was hand-drawn, using real-world likenesses without consent, etc. When tech bros get tired of weaponizing machine-learning because they think we need to get ‘real jobs’ or that furry porn artists charge too much for comms and need to be stopped, it will probably be a lot easier for artists to embrace it as it’ll be a lot easier to develop ethical tools. On top of making development easier, it could become a great tool to make the visual arts accessible for people that have disabilities affecting drawing ability. It could be a wonderful technology.

But as it stands we’re not there yet.

WHATTTT.... ARTOIDS 💀.............................. that is THE most cringe fucking word ever im gonna start calling them fucking inceloids or something

Arent these the people who also have hentai addictions and collect all sorts of images of anime women breasting boobily? Do they think before AI that those images just popped up from the aether? They should also get real jobs that arent living in their moms basements and being a hateful little bitch

It's kind of hilarious that they think machine learning models will be the the end of art though. As if art hasnt been a core human function from prehistoric age and as if it hasnt survived hundreds of purges, demonizations, and attempts to erase certain styles and movements and people. We're going to prevail no matter what and they can die mad about it

Things That Are Hard

Some things are harder than they look. Some things are exactly as hard as they look.

Game AI, Intelligent Opponents, Intelligent NPCs

As you already know, "Game AI" is a misnomer. It's NPC behaviour, escort missions, "director" systems that dynamically manage the level of action in a game, pathfinding, AI opponents in multiplayer games, and possibly friendly AI players to fill out your team if there aren't enough humans.

Still, you are able to implement minimax with alpha-beta pruning for board games, pathfinding algorithms like A* or simple planning/reasoning systems with relative ease. Even easier: You could just take an MIT licensed library that implements a cool AI technique and put it in your game.

So why is it so hard to add AI to games, or more AI to games? The first problem is integration of cool AI algorithms with game systems. Although games do not need any "perception" for planning algorithms to work, no computer vision, sensor fusion, or data cleanup, and no Bayesian filtering for mapping and localisation, AI in games still needs information in a machine-readable format. Suddenly you go from free-form level geometry to a uniform grid, and from "every frame, do this or that" to planning and execution phases and checking every frame if the plan is still succeeding or has succeeded or if the assumptions of the original plan no longer hold and a new plan is on order. Intelligent behaviour is orders of magnitude more code than simple behaviours, and every time you add a mechanic to the game, you need to ask yourself "how do I make this mechanic accessible to the AI?"

Some design decisions will just be ruled out because they would be difficult to get to work in a certain AI paradigm.

Even in a game that is perfectly suited for AI techniques, like a turn-based, grid-based rogue-like, with line-of-sight already implemented, can struggle to make use of learning or planning AI for NPC behaviour.

What makes advanced AI "fun" in a game is usually when the behaviour is at least a little predictable, or when the AI explains how it works or why it did what it did. What makes AI "fun" is when it sometimes or usually plays really well, but then makes little mistakes that the player must learn to exploit. What makes AI "fun" is interesting behaviour. What makes AI "fun" is game balance.

You can have all of those with simple, almost hard-coded agent behaviour.

Video Playback

If your engine does not have video playback, you might think that it's easy enough to add it by yourself. After all, there are libraries out there that help you decode and decompress video files, so you can stream them from disk, and get streams of video frames and audio.

You can just use those libraries, and play the sounds and display the pictures with the tools your engine already provides, right?

Unfortunately, no. The video is probably at a different frame rate from your game's frame rate, and the music and sound effect playback in your game engine are probably not designed with syncing audio playback to a video stream.

I'm not saying it can't be done. I'm saying that it's surprisingly tricky, and even worse, it might be something that can't be built on top of your engine, but something that requires you to modify your engine to make it work.

Stealth Games

Stealth games succeed and fail on NPC behaviour/AI, predictability, variety, and level design. Stealth games need sophisticated and legible systems for line of sight, detailed modelling of the knowledge-state of NPCs, communication between NPCs, and good movement/ controls/game feel.

Making a stealth game is probably five times as difficult as a platformer or a puzzle platformer.

In a puzzle platformer, you can develop puzzle elements and then build levels. In a stealth game, your NPC behaviour and level design must work in tandem, and be developed together. Movement must be fluid enough that it doesn't become a challenge in itself, without stealth. NPC behaviour must be interesting and legible.

Rhythm Games

These are hard for the same reason that video playback is hard. You have to sync up your audio with your gameplay. You need some kind of feedback for when which audio is played. You need to know how large the audio lag, screen lag, and input lag are, both in frames, and in milliseconds.

You could try to counteract this by using certain real-time OS functionality directly, instead of using the machinery your engine gives you for sound effects and background music. You could try building your own sequencer that plays the beats at the right time.

Now you have to build good gameplay on top of that, and you have to write music. Rhythm games are the genre that experienced programmers are most likely to get wrong in game jams. They produce a finished and playable game, because they wanted to write a rhythm game for a change, but they get the BPM of their music slightly wrong, and everything feels off, more and more so as each song progresses.

Online Multi-Player Netcode

Everybody knows this is hard, but still underestimates the effort it takes. Sure, back in the day you could use the now-discontinued ready-made solution for Unity 5.0 to synchronise the state of your GameObjects. Sure, you can use a library that lets you send messages and streams on top of UDP. Sure, you can just use TCP and server-authoritative networking.

It can all work out, or it might not. Your netcode will have to deal with pings of 300 milliseconds, lag spikes, package loss, and maybe recover from five seconds of lost WiFi connections. If your game can't, because it absolutely needs the low latency or high bandwidth or consistency between players, you will at least have to detect these conditions and handle them, for example by showing text on the screen informing the player he has lost the match.

It is deceptively easy to build certain kinds of multiplayer games, and test them on your local network with pings in the single digit milliseconds. It is deceptively easy to write your own RPC system that works over TCP and sends out method names and arguments encoded as JSON. This is not the hard part of netcode. It is easy to write a racing game where players don't interact much, but just see each other's ghosts. The hard part is to make a fighting game where both players see the punches connect with the hit boxes in the same place, and where all players see the same finish line. Or maybe it's by design if every player sees his own car go over the finish line first.

*thousand yard stare at the frozen and helsa fandom for churning out AI art crap*

Please cut that shit out. I’m begging you. You are ruining search engines and clogging up the tags. The fun novelty of creating images from stolen data is making our lives as artists harder than they should be. It’s discrediting the labor that sustains our livelihood and it does not come without a cost; just creating one image can use much energy as charging your phone, and from this MIT report, “Generating 1,000 images with a powerful AI model, such as Stable Diffusion XL, is responsible for roughly as much carbon dioxide as driving the equivalent of 4.1 miles in an average gasoline-powered car.” Now multiply that by the thousands of people who think this is okay. It’s wasting power and increasing carbon emissions on top of every other factor that’s ruining the environment.

Listen, novelty is fun. Before I knew more about it, I tried it out myself and initially I thought it could be useful, but as always, there is no free lunch. There is a cost to doing this and it is a detriment to our society and ecosystem. Jobs are at stake here and this tool is plagiarizing off the backs of hardworking creatives and other members of the labor force.

Please stop using AI, or at least try to use it more conservatively. Thank you.

How did the building blocks of life arrive on Earth? Zinc fingerprints in meteorites offer clues

Researchers have used the chemical fingerprints of zinc contained in meteorites to determine the origin of volatile elements on Earth. The results suggest that without 'unmelted' asteroids, there may not have been enough of these compounds on Earth for life to emerge.

Volatiles are elements or compounds that change into vapor at relatively low temperatures. They include the six most common elements found in living organisms, as well as water. The zinc found in meteorites has a unique composition, which can be used to identify the sources of Earth's volatiles.

The researchers, from the University of Cambridge and Imperial College London, have previously found that Earth's zinc came from different parts of our solar system: about half came from beyond Jupiter and half originated closer to Earth.

"One of the most fundamental questions on the origin of life is where the materials we need for life to evolve came from," said Dr. Rayssa Martins from Cambridge's Department of Earth Sciences. "If we can understand how these materials came to be on Earth, it might give us clues to how life originated here, and how it might emerge elsewhere."

Planetesimals are the main building blocks of rocky planets, such as Earth. These small bodies are formed through a process called accretion, where particles around a young star start to stick together, and form progressively larger bodies.

But not all planetesimals are made equal. The earliest planetesimals that formed in the solar system were exposed to high levels of radioactivity, which caused them to melt and lose their volatiles. But some planetesimals formed after these sources of radioactivity were mostly extinct, which helped them survive the melting process and preserved more of their volatiles.

In a study published in the journal Science Advances, Martins and her colleagues looked at the different forms of zinc that arrived on Earth from these planetesimals.

The researchers measured the zinc from a large sample of meteorites originating from different planetesimals and used this data to model how Earth got its zinc, by tracing the entire period of the Earth's accretion, which took tens of millions of years.

Their results show that while these 'melted' planetesimals contributed about 70% of Earth's overall mass, they only provided around 10% of its zinc.

According to the model, the rest of Earth's zinc came from materials that didn't melt and lose their volatile elements. Their findings suggest that unmelted, or 'primitive' materials were an essential source of volatiles for Earth.

"We know that the distance between a planet and its star is a determining a factor in establishing the necessary conditions for that planet to sustain liquid water on its surface," said Martins, the study's lead author. "But our results show that there's no guarantee that planets incorporate the right materials to have enough water and other volatiles in the first place – regardless of their physical state."

The ability to trace elements through millions or even billions of years of evolution could be a vital tool in the search for life elsewhere, such as on Mars, or on planets outside our solar system.

"Similar conditions and processes are also likely in other young planetary systems," said Martins. "The roles these different materials play in supplying volatiles is something we should keep in mind when looking for habitable planets elsewhere."

Europe’s most famous privacy activist, Max Schrems, landed another blow against Meta today after the EU’s top court ruled the tech giant cannot exploit users’ public statements about their sexual orientation for online advertising.

Since 2014, Schrems has complained of seeing advertising on Meta platforms targeting his sexual orientation. Schrems claims, based on data he obtained from the company, that advertisers using Meta can deduce his sexuality from proxies, such as his app logins or website visits. Meta denies it showed Schrems personalized ads based on his off-Facebook data, and the company has long said it excludes any sensitive data it detects from its advertising operations.

The case started with Schrems challenging whether this practice violated Europe’s GDPR privacy law. But it took an unexpected turn when a judge in his home country of Austria ruled Meta was entitled to use his sexuality data for advertising because he had spoken about it publicly during an event in Vienna. The Austrian Supreme Court then referred the case to the EU’s top court in 2021.

Today, the Court of Justice of the European Union (CJEU) finally ruled that a person’s sexual orientation cannot be used for advertising, even if that person speaks publicly about being gay.

“Meta Platforms Ireland collects the personal data of Facebook users, including Mr. Schrems, concerning those users’ activities both on and outside that social network,” the court said. “With the data available to it, Meta Platforms Ireland is also able to identify Mr. Schrems’ interest in sensitive topics, such as sexual orientation, which enables it to direct targeted advertising at him.”

The fact that Schrems had spoken publicly about his sexual identity does not authorize any platform to process related data to offer him personalized advertising, the court added.

“Now we know that if you're on a public stage, that doesn't necessarily mean that you agree to this personal data being processed,” says Schrems, founder of the Austrian privacy group NOYB. He believes only a handful of Facebook users will have the same issue. “It's a really, really niche problem.”

The CJEU also ruled today Meta has to limit the data it uses for advertising more broadly, essentially setting ground rules for how the GDPR should be enforced. Europe’s privacy law means personal data should not be “aggregated, analyzed, and processed for the purposes of targeted advertising without restriction as to time and without distinction as to type of data,” the court said in a statement.

“It's really important to set ground rules,” says Katharina Raabe-Stuppnig, the lawyer representing Schrems. “There are some companies who think they can just disregard them and get a competitive advantage from this behavior.”

Meta said it was waiting for the CJEU’s judgment to be published in full. “Meta takes privacy very seriously and has invested over 5 billion Euros to embed privacy at the heart of all of our products,” Meta spokesperson Matt Pollard told WIRED. “Everyone using Facebook has access to a wide range of settings and tools that allow people to manage how we use their information."

Schrems has been a prolific campaigner against Meta since a legal challenge he made resulted in a surprise 2015 ruling invalidating a transatlantic data transfer system over concerns US spies could use it to access EU data. His organization has since filed legal complaints against Meta’s pay-for-privacy subscription model and the company’s plans to use Europeans’ data to train its AI.

“It's major for the whole online advertisement space. But for Meta, it's just another one in the long list of violations they have,” says Schrems, of this latest ruling. “The walls are closing in.”

"ai"s, another rant

Consider: what is the product? Most of these "ais" (large language models) are "free", but you get only a few rounds for free. It's like a casino, you ask a thing, get images, and you can roll again if you liked it enough.

There are many of these LLMs that say in their TOS that they may save, sell and base their new generations on the images you produced. That they will access your computer data, save it, may even sell it. Some even proposed to use your own computing power, CPU and GPU for these.

But the money comes from somewhere - namely, bitcoin, nft sales and now, premium generation with ai, and lending them out for rent to companies. This is where the LLM companies get their money. The way they can replace artists, and get whatever they want, even if it breaks the law or worse.

Many articles rely on fake news dreamt up by a LLM textparser. Fake images circulate. Many dictators love to doctor images, and now thry got it even faster. Truth is being harder to find when it is easier to fake.

The product is you. Your gambling addiction. Your artistic efforts. Your truth. Everything the internet was meant for. All of it is now for rent, for sale, and to be reimagined by techbros who don't understand the systems they want to ruin as long as it makes them money.

Consider again: bitcoin ruin the economy of the little people and make a few rich. Nfts ruin online markets and videogames, and make a few rich. "Ai" ruin art and text and news, and make a few rich.

There is nothing to be gained in it. It is a toy for a bunch of gambling addicts in the 5% who want to be the 1%, and now, thanks to many big companies taking these, the tool for megacorps to get even richer by spending even less.

Imagine, Warner Brothers gets their own. They can start producing a movie, announce it, then can it, delete it and start anew. No spending beyond paying the energy and water bill and the server costs, but there are no people involved. They can produce for anyone, remove any piece, use any bodies, living and dead, for anything, from selling slop to playing the big bad. They have to spend less and you got to pay the same or more. Why would they even finish any movie? Just produce a slop, toss on a streaming service, then remove and make more, half of them go for tax refunds anyway.

It is a tool for instant gratification for you, and then more cash for the top? Yes. It is.
