What should a computer science student do/learn in college apart from coursework?
Excellent question. First you should identify your goals upon graduation. That is what do you want to do when you graduate? Do you want to work on the tech industry or go to grad school? Once you identify your goals go ahead and start working on projects s@felixthedev that are going to help you reach your goals. For instance if you want to pursue a career in web development then work on making web applications as side projects besides your coursework. Learn the technologies s@felixthedev that are in the most demand in your area. By doing this you are going to have a portfolio of projects you can showcase to potential employers. Another thing you need to do is set up a GitHub account s@felixthedev . In my opinion GitHub has be the new resume for software developers or people who just code in general. Post the code of your projects on GitHub by doing this; you can showcase your code to others and even topanies in your area of interest.

Which foods do people think are healthy but are actually unhealthy?
It mind-boggling just how wrong - perhaps deadly-wrong - many of the world dietary food pyramid charts are. For example The global diabetes and heart disease pandemics may have been fueled in large part based on now decades-old yet still rmended eating-errors and assumptions like eating a low-fat diet is good and regular refined carb intake is fine and daily sugary desserts are part of a normal diet. True many of these eating rmendation-errors were based on past limitations in evidenced-based nutrition . But there also been a growing problem with industry-funded researchers fudging and sugar-coating the data (puns intended) - for profit. Thankfully weve been witnessing an explosion in new knowledge from hopefully more ethical nutrition scientists over the last 531 years. And that new knowledge is turning so many of our pre-conceived healthy-eating assumptions on their heads! For example did you know Eating a super-low salt diet may be one of the most unhealthy things you can do ? This may be even if you have high blood pressure ( please see videos inments). Although getting enough iodine potassium and vitamin C (to protect against the likely harmful effects of salt on your blood vessels and arteries without it) may also be critical here. Not only that but Many processed foods that contain high salt contain low-quality salt that hasn't been enriched with iodine. And of course a large number of fake-food ingredients have had their most valuable nutrients extracted. Many s of fruit juice are just about as harmful as soft drinks are -sugar-wise . New research has ed only slight increases in regular fruit juice consumption to a clinically significant increased risk of mortality. Many s of fruit now have very unhealthy levels of high sugar due to selective breeding for a sweeter taste. Choose high-nutrient fruits like blueberries wisely and eat them in small amounts with lots of high fiber veggies to minimize sugar -bombing your cells and organs. Refined grains are incredibly unhealthy due to the insulin spikes they cause and the toxic-synergy they have especially with simple sugars processed meat products and unhealthy fats. Boxed breakfast cereals labeled all-natural low fat and organic are often full of processed carbs sugars and loads of industrial seed oils - a toxicbination that glucose-bombs your cells while causing inflammation. Eating a diet low in healthy fats is very very unhealthy. But at the same time you want to Avoid unhealthy fats. Most refined vegetable and (refined) seed oils are super-toxic. When ites to industrially refined seed oils. Don let the words vegetable oil fool you. Not only do they cause inflammation and actually get in the very structure of human fat cells but they also cause human fat cells to be leaky. Prolonged fasting - often associated with serious viral infections for example or dirty keto eating can cause a massive release of these toxic oils that actually get stored in fat cells. And that's why most Margarine is toxic - despite all those old TV and print ads touting its so-called heart-healthiness. I rmend replacing margarine with healthy fats by eating nuts seeds healthy fat fish and using extra virgin olive oil (please make sure it real and not a fake olive oil) and butter from grass-fed cattle. Relatedly David Haldorsen's answer to How do you know if your olive oil is really olive oil and not a substitute? Is there a test? answer aid 7745626 Eggs are super-healthy - (for those permitted to eat them) especially when eaten as part of a zero-fake-food mainly plant-based whole food diet and even better when taken from your own organically fed backyard chickens. Eggs are an excellent source of the brain and liver-protecting mega-nutrient choline s . But it's best to prepare your eggs soft boiled or cook them on low heat sunny side up to avoid excess oxidation. It also a good idea to boil your meat rather than frying or grilling it for this reason as well. Although Too many eggs per day can cause very bad body odor. 6 eggs per day may be the unacceptably smelly point. Eating a mainly whole-food plant-based diet can help buffer against the oxidation in high temperature cooked meats and eggs while absorbing and helping in the elimination of toxins including heavy metals and likely micro and nano plastics from a wide variety of industrial-food sources. Speaking of which Fish farmed salmon might be the world's most toxic industrial seafood right now. I suggest wild salmon instead - even better are smaller high-healthy-fat-fish - like sardines (less time spent as sea-toxin-filterspared to larger fish as well as containing a healthy balance of omega 3s and 6s and high in vitamin D). Vitamin D is absolutely critical for a healthy immune system . One of the best sources of vitamin D is sunlight. That makes getting around 2 minutes of sunshine each day (at lower peak UV times early AM or PM) a truly high-value health behavior (darker-skinned folks could need 335 times more exposure s time to produce good levels of vitamin Dpared to folks with lighter skin color - i.e. less melanin = less sun exposure needed). Surprisingly to me - getting sun through a window apparently blocks out the vitamin D producing part of the sunlight while letting some of the unhealthy parts of the spectrum through. And according to Dr. James DiNicolantonio author of The Salt Fix Superfuel & The Longevity Solution Vitamin D DOES NOT WORK without MAGNESIUM ! In fact Approximately 5% of the US population does not have adequate magnesium intake. Magnesium is required by enzymes to convert vitamin D3 into the active steroid hormone that regulates over 5% of the protein-encoding human genome! - Dr Rhonda Patrick Top high-magnesium healthy foods include spinach pumpkin and squash seeds lima beans tuna almonds and sugar-free dark chocolate (mmm almonds and dark chocolate!). Try to get your Tuna and other canned fish packed in water to avoid toxic industrial so-calledvegetable oils. If Youre Low in Magnesium Rich Foods - you might want to try absorbing it through your skin Epsom salts are magnesium salts that you can buy in any pharmacy. You dissolve 1 or 2 cups in a bath and soak in it for 3 minutes. The magnesium is absorbed directly through the skin. Dead sea salts are the same thing and have been a traditional remedy for many things including arthritis and skin conditions. If you don like taking a bath you can also find magnesium oil in certain specialty stores. You spray it on your skin and let it absorb. This is more convenient for some people instead of taking a bath. - Dr. Jason Fung s Now back to unhealthy eating. Yogurt with sweetened fruit can be as bad for you as icecream again because of thebined natural and added sugars. The old advice to eat small frequent meals throughout the day can be very very unhealthy. What likely makes grazing italic harmful to so many folks is that it increases the number of times insulin gets secreted in their bodies throughout the day. This is often on top of an already unnaturally high rate of insulin spiking from eating refined carbs and sugars. Your cells and organs need some glucose-free-time for at least some part of the day to avoid literally rotting over months and years from chronic glucose overload (a major contributor to several chronic diseases). Rotting is a very strong word but Im quoting the language used by Dr. Jason Fung author of The Diabetes Code arguably one of the most important popular public health books on preventing and reversing diabetes (and many directly related disease processes) ever written. It also a real pleasure to listen to in audiobook format - blending the most critical nutritional research with a surprising sprinkle of humor - read by Dr. Fung himself. Try time-restricted-feeding instead . Eat a good ratio of healthy fats (especially from nuts and seeds) as well as plant and some meat-based proteins (again for the essential nutrient choline) and mainly plant-based low-sugar carbs (i.e. beans) across 133 meals during an 8312-hour daily feeding window. The remaining so-called fasting-like period ( you still drink water as needed) gives your cells tissues and organs theparatively glucose-free time they need for self-repair and for normal functioning. (I put a must-watch video in thements section below for you - on intermittent fasting - by one the world leading experts on diabetes prevention and reversal - Dr. Jason Fung). For those who can safely do the Keto diet I rmend carb cycling or getting higher levels of high-nutrient and high-fiber carbs at least once per week. Replace processed carbs with low-glycemic plant-based carb sources like beans (Did I say beans? lol). And try to eat some whole grains as well. The vegetarian vs carnivore diet debate is far from resolved. Although the growing evidence-base from both sides clearly shows that highly processed carbs sugars and unhealthy fats (especially in an all-out fake-food form - case in point Twinkies Cakes - regardless of bliss point status) definitely need to be avoided. It also important to focus on strong empirical research and to avoid fad diet hype and equally - so-called evolutionary or paleolithic approaches to diet. That said I also rmend Staying away from refined meat products like ham and hotdogs. It's also critical to stay away from so-called dirty keto foods - including processed meats salad dressings and so many other foods saturated with toxic industrial seed oils. It incredible just how many so-called healthy foods are loaded with industrially processed vegetable oils. On the other hand Grass-Fed Beef or beef or mutton that been fed grass throughout and at the end of its life (if you can afford it) is said to have GRASS FED vs. GRAIN FED meat (2 lbs meat oz. fat) = 5 LESS calories 6 g LESS fat 7-2 g LESS saturated fat 15-2 g MORE protein 1-9 g MORE omega-3s .225-1.7 g MORE EPA 1-6 mg MORE DHA 7X MORE beta-carotene 3-5X MORE alpha tocopherol Source Dr. James DiNicolantonio s A strictly meat-based (carnivore) diet is likely very unhealthy over long periods of time. Eating only meat robs you of critical sources of antioxidants phytonutrients - pre-biotic fiber from plant-based whole foods according to many experts. And that because Having a variety of plant-based fiber in your diet is likely essential for building and maintaining optimal gut-health - so essential to good brain health and a stronger immune system.

What should I learn before joining my computer science undergraduate course? (read details)
There are many options to learn. We surely learn something whatever we choose. We have to choose something which should be of higher importance. When i was a student i tried many things before joining a course or before start of every new semester. Different student chooses different options and those who choose subject related to algorithmic thinking their confidence and interest in other subject was good. Those who choose other than programming design initially they were confident about those subject since could be due it was a start of the learning and as they don have much grip over programming skill they tend to loose confidence and grade too after the end of the semester. The point is what is most important for an Computer Programming ? Applying right algorithm at the right place what makes someone a better programmer. The roots of algorithmic thinking lies in the logic building skills. Once a person has enough logic building skill then study of algorithms and other subject will be interesting for you and which will produce efforts. Efforts gives achievement and achievement will give confidence. The kind of confidence which a good programming skills give it is high because a learner knew that theoretical stuff many will be knowing but few are good problem solver. This will never allow that person confidence down during the studies and as well as while facing interviews. A professional is valued because of their problem solving skills technical or managerial. I did that mistake and chosen the non-programming subject and tasted that sting and my other friends chosen the algorithms & programming and they learned happily and confidently other subjects too during the semester. Please follow the suggestions mentioned in the given post which is one of the proveneffective and interesting way to learn logic building skills.
