well, that was easy 15 epochs till 100% accuracy.
"At this point LLMs-in-the-classroom apologists should be embarrassed," she tweeted in a thread that went viral last month. "Students aren't just using this stuff as a 'problem-solving tool' or whatever BS people spout, they're using it to forget how to talk."
Shaping AI through Cultural Diversity
In another break from the usual programming... As a retired machine learning scientist, I wanted to share a few thoughts about future AI developments, since there's a lot of vague concern right now. Here are what I see to be the main issues.
AI is derivative. It's good at copying but a) lacks all originality (other than that occasional fluke maybe) and b) lacks human values, imparting a certain chill.
It may for example get good at producing pulp fiction, and you may mindlessly consume it in large quantities one day, but it won't make you feel good. We won't see ourselves deeply reflected in this content. It won't encourage intelligence and sensitivity.
We've seen already that industry will try to use it to replace decision workers, such as in filtering hate speech from your social media, or rating your job application, but that it will show no interest in edge cases, feeding into a society that's as derivative and hostile to difference as it is itself. We may start to develop weird mannerisms to get past these flawed gatekeepers. There may be pointless bubbles, e.g. if the AI randomly likes certain postcodes so house prices rise there.
It will get better and better at not making mistakes, such as driving your car off the road, but will never really understand that hitting a child is worse than hitting the central reservation. It may even get better at protecting life that you, as a driver, already are, but it won't generalise human values to novel situations. It may well be a greater danger to the life of non-European children. It will be safer if you don't have anything very unusual near the road, or change anything.
AI will become a major race issue at some point.
On the plus side, one day your cataract operation, for example, will be done perfectly virtually every time, and cheaper. I do think we'll be safer, and faster, on the road. We will extend uniformity of outcome into more complex, resistant areas. Safety is a domain where the target outcome is clear, and AI is ultimately suited. There will likely be inroads into much more complex manufacturing and automation. There will be job loss.
There is vast potential for flooding the internet with misleading content. Spam on steroids. Good content will be drowned. It might kill the internet as we know it. This is the decline of a golden age of trying to say something helpful on the internet, and one or two people possibly reading it. The internet is about to become a terrific weed patch.
People are making a valid living producing fairly derivative creative output, for example much high street fashion design, or domestic architecture, and there's nothing wrong with that. AI could move into that space. This kind of "everyday art" will get a little bit cheaper and a little bit less human, and that will be sad.
Companies will certainly try to sell you an AI of various kinds, but here it helps to remember that the word "intelligence" is part of the hype. It will be cleverly presented to keep you entertained. It will be good for some things and bad for others, like previous software, whilst even easier to anthropomorphise. Have fun, if you're into it.
Key points:
AI as gatekeeper - BAD
AI as creator - SAD
AI as surgeon, driver or skilled line worker - take it slow and build trust, with a close eye on outcomes for minorities
AI as friend and entertainer - relatively harmless?
In summary, I think my main concern is that AI is going to be hostile to difference.
watching @nanowrimo within a single hour:
make an awful, ill-conceived, sponsored post about "responsible"/"ethical" uses of ai in writing
immediately get ratio'd in a way i've never seen on tumblr with a small swarm of chastising-to-negative replies and no reblogs
start deleting replies
reply to their own post being like 'agree to disagree!!!' while saying that ai can TOTALLY be ethical because spellcheck exists!! (???) while in NO WAY responding to the criticisms of ai for its environmental impact OR the building of databases on material without author consent, ie, stolen material, OR the money laundering rampant in the industry
when called out on deleting replies, literally messaged me people who called them out to say "We don't have a problem with folks disagreeing with AI. It's the tone of the discourse." So. overtly stated tone policing.
get even MORE replies saying this is a Bad Look, and some reblogs now that people's replies are being deleted
DISABLE REBLOGS when people aren't saying what nano would prefer they say
im juust in literal awe of this fucking mess.

How to Maintain Your Muscle Mass and Strength as You Age
If you want to stay strong, healthy and independent as you get older, you need to take care of your muscles. Muscle mass and strength tend to decline with age, which can lead to problems such as falls, fractures, disability and even death. This condition is called sarcopenia, and it affects up to 50% of people 80 and over [2].
But don't worry, you can prevent or slow down sarcopenia by following some simple tips. Here are five ways to maintain your muscle mass and strength as you age:
Work out with weights regularly. Resistance training is the best way to stimulate muscle growth and prevent muscle loss. You should aim for at least two sessions per week, working all the major muscle groups of your body. You can use free weights, machines, bands or bodyweight exercises. The key is to challenge your muscles with enough intensity and volume, and progressively increase them over time [1] [3].
Eat plenty of protein. Protein is the building block of muscle, and you need enough of it to support muscle repair and growth. As you age, your protein needs may increase, especially if you are physically active. A good rule of thumb is to consume 0.8 to 1.2 grams of protein per kilogram of body weight per day, preferably from high-quality sources such as lean meat, fish, eggs, dairy, soy or whey [1] [3].
Consume enough calories. Muscle growth requires energy, and if you don't eat enough calories, your body may break down muscle tissue for fuel. This can lead to muscle loss and weakness. To prevent this, you should eat enough calories to maintain your weight or slightly above it if you want to gain muscle. You should also choose nutritious foods that provide vitamins, minerals, antioxidants and other beneficial compounds for your health [1] [3].
Combine cardio and resistance training. Aerobic exercise such as brisk walking, jogging, biking or swimming is good for your heart, lungs and brain health. It can also help you burn calories and fat, which can improve your body composition and prevent obesity-related sarcopenia. However, too much cardio can interfere with muscle growth if you don't balance it with resistance training. A good strategy is to do cardio for 30 minutes per day, five days per week, and resistance training for two hours per week [1] [4].
Get enough rest and sleep. Rest and sleep are essential for muscle recovery and growth. When you sleep, your body releases hormones such as growth hormone and testosterone that stimulate muscle synthesis. Sleep also helps you reduce stress and inflammation, which can impair muscle function. You should aim for seven to nine hours of quality sleep per night, and avoid caffeine, alcohol or screen time before bed [1] [3].
By following these tips, you can maintain your muscle mass and strength as you age, and enjoy a better quality of life. Remember that it's never too late to start exercising and eating well for your muscles. You can always improve your strength and coordination with regular practice and consistency.

How to manage your hunger, cravings and appetite while following a strict diet for bodybuilding
If you are a bodybuilder, you know how important it is to follow a strict diet that provides you with enough protein, carbohydrates, fats, vitamins and minerals to support your muscle growth and recovery. However, you also know how challenging it can be to stick to your diet when you are constantly feeling hungry, craving for junk food or losing your appetite due to stress or boredom. In this blog post, we will share with you some tips and tricks on how to manage your hunger, cravings and appetite while following a strict diet for bodybuilding.
Tip #1: Drink plenty of water Water is essential for your health and performance, as it helps you stay hydrated, regulate your body temperature, flush out toxins and lubricate your joints. Water also helps you feel fuller and suppress your appetite, as it takes up space in your stomach and prevents you from overeating. A good rule of thumb is to drink at least 2 liters of water per day, or more if you exercise intensely or sweat a lot. You can also add some lemon juice, cucumber slices or mint leaves to your water to make it more refreshing and flavorful.
Tip #2: Eat more fiber Fiber is a type of carbohydrate that is not digested by your body, but instead passes through your digestive system and helps you maintain a healthy bowel movement. Fiber also helps you feel fuller and satisfied for longer, as it slows down the absorption of sugar and fat in your bloodstream and reduces the spikes and drops in your blood glucose levels. Fiber also helps you lower your cholesterol and blood pressure levels, which are important for your heart health. Some good sources of fiber include fruits, vegetables, whole grains, beans, nuts and seeds.
Tip #3: Eat more protein Protein is the most important macronutrient for bodybuilders, as it provides you with the amino acids that are the building blocks of your muscles. Protein also helps you feel fuller and satiated for longer, as it takes more time and energy to digest than carbohydrates or fats. Protein also helps you preserve your muscle mass and boost your metabolism, which means you burn more calories even at rest. Some good sources of protein include lean meat, poultry, fish, eggs, dairy products, soy products and protein supplements.
Tip #4: Eat more healthy fats Fats are not the enemy of bodybuilders, as long as they are healthy and consumed in moderation. Healthy fats help you feel fuller and satisfied for longer, as they provide you with energy and essential fatty acids that support your brain function, hormone production and skin health. Healthy fats also help you lower your inflammation and improve your insulin sensitivity, which are important for your muscle growth and recovery. Some good sources of healthy fats include olive oil, avocado, nuts, seeds, fish oil and flaxseed oil.
Tip #5: Eat more frequently Eating more frequently does not mean eating more calories, but rather spreading them out throughout the day. Eating more frequently helps you manage your hunger, cravings and appetite better, as it prevents you from getting too hungry or too full at any given time. Eating more frequently also helps you maintain a steady supply of nutrients to your muscles and organs, which supports your performance and recovery. A good strategy is to eat 5 to 6 small meals per day, or 3 main meals with 2 to 3 snacks in between.
Tip #6: Plan ahead Planning ahead is crucial for sticking to your diet and avoiding temptations. Planning ahead means preparing your meals in advance, packing your snacks with you when you go out or travel, shopping for healthy ingredients and avoiding junk food aisles in the supermarket. Planning ahead also means setting realistic goals for yourself, tracking your progress and rewarding yourself for your achievements. Planning ahead also means having a backup plan in case something goes wrong or unexpected happens.
Tip #7: Cheat smartly Cheat meals are not forbidden for bodybuilders, as long as they are done smartly and occasionally. Cheat meals can help you satisfy your cravings, boost your metabolism and morale, and prevent you from feeling deprived or bored with your diet. However, cheat meals should not be used as an excuse to binge on unhealthy food or sabotage your progress. A good rule of thumb is to limit your cheat meals to once a week or once every two weeks, depending on your goals and preferences. You should also choose your cheat meals wisely, opting for quality over quantity and moderation over excess.

How to use cheat meals, refeeds and carb cycling to enhance your metabolism and performance
If you are following a strict diet for fat loss or muscle gain, you might be wondering if there is a way to enjoy some of your favorite foods without sabotaging your progress. The answer is yes, but you need to be smart about it. In this blog post, I will explain how to use cheat meals, refeeds and carb cycling to enhance your metabolism and performance, while still achieving your goals.
Cheat meals are occasional indulgences that allow you to eat whatever you want, without counting calories or macros. They are meant to satisfy your cravings, boost your mood and prevent diet burnout. However, they are not an excuse to binge or overeat. You should limit your cheat meals to once a week or less, and keep them within a reasonable portion size. Cheat meals can also have some benefits for your metabolism and hormones, as they can increase your leptin levels, which regulate your appetite and energy expenditure.
Refeeds are planned increases in your calorie intake, mainly from carbohydrates, that last for a day or more. They are designed to replenish your glycogen stores, which are depleted by low-carb diets. Glycogen is the stored form of glucose in your muscles and liver, and it is essential for optimal performance and recovery. Refeeds can also boost your metabolism and hormones, as they can increase your thyroid function, insulin sensitivity and testosterone levels.
Carb cycling is a strategy that involves alternating between high-carb and low-carb days, depending on your training schedule and goals. It allows you to take advantage of the benefits of both high-carb and low-carb diets, without the drawbacks of either. High-carb days can enhance your performance, strength and muscle growth, while low-carb days can promote fat loss, ketosis and inflammation reduction.
To use cheat meals, refeeds and carb cycling effectively, you need to consider several factors, such as your body type, activity level, goal, calorie intake and macronutrient ratio. There is no one-size-fits-all approach, so you need to experiment and find what works best for you. Here are some general guidelines to get you started:
If you are lean and active, you can benefit from more frequent and higher-calorie cheat meals and refeeds, as you have a faster metabolism and higher insulin sensitivity. You can also use carb cycling to optimize your performance and recovery on different days.
If you are overweight and sedentary, you should limit your cheat meals and refeeds to once every two weeks or less, as you have a slower metabolism and lower insulin sensitivity. You should also stick to a low-carb diet most of the time, as it can help you lose fat and improve your health markers.
If you are somewhere in between, you can have a cheat meal or a refeed once a week or every 10 days, depending on your progress and how you feel. You can also use a moderate-carb diet that matches your activity level and goal.
Remember that cheat meals, refeeds and carb cycling are not magic bullets that will make you lose fat or gain muscle overnight. They are tools that can help you break through plateaus, improve your adherence and enjoy your diet more. However, they still require discipline, consistency and moderation. The most important thing is to follow a balanced diet that meets your nutritional needs and supports your lifestyle.
What are cheat meals, refeeds and carb cycling?
Cheat meals are occasional indulgences in foods that are not part of your regular diet, such as pizza, burgers, ice cream, etc. They are meant to satisfy your cravings and boost your morale, but they should not be abused or used as an excuse to binge.
Refeeds are planned increases in calorie intake, usually from carbohydrates, that are done once a week or every few weeks, depending on your goals and body type. They are meant to replenish your glycogen stores, which are the main source of energy for your muscles, and to prevent metabolic slowdown, which is the decrease in calorie expenditure that occurs when you diet for a long time.
Carb cycling is a strategy that involves alternating between high-carb and low-carb days throughout the week. It is meant to optimize your hormone levels, especially insulin and leptin, which regulate your appetite and fat storage. It also allows you to have more energy and strength on your high-carb days, which are usually aligned with your most intense workouts.
How can cheat meals, refeeds and carb cycling enhance your metabolism and performance?
Cheat meals, refeeds and carb cycling can have several benefits for your metabolism and performance, such as:
Preventing metabolic adaptation: When you diet for a long time, your body adapts by lowering your metabolic rate, which means you burn fewer calories at rest and during activity. This makes it harder to lose fat and easier to regain it. By increasing your calorie intake periodically, you can trick your body into thinking that there is no food shortage and keep your metabolism high.
Restoring glycogen levels: Glycogen is the stored form of glucose in your muscles and liver. It is used as fuel for high-intensity exercise, such as weight lifting or sprinting. When you follow a low-carb diet or exercise intensely, you deplete your glycogen stores. This can impair your performance and recovery. By consuming more carbs on certain days, you can replenish your glycogen levels and improve your energy and endurance.
Balancing hormones: Hormones are chemical messengers that regulate various processes in your body, such as appetite, mood, fat storage, muscle growth, etc. When you diet or exercise, some hormones can become imbalanced. For example, insulin can become less sensitive, which means it takes more glucose to lower your blood sugar levels. This can lead to cravings, hunger and fat gain. Leptin can also become less responsive, which means it takes more food to make you feel full. This can lead to overeating and weight regain. By manipulating your carb intake, you can improve your insulin and leptin sensitivity and control your appetite and fat loss.
