I'm frustrated reading comments here that repeatedly say "Calories in, calories out", "law of thermodynamics", etc.

Frustrated because, for one thing, this approach is extremely discouraging to people who want to, or are in the process of, losing weight. "Jesus you're so dumb, how can you not understand this one simple thing that you merely have to eat less?"

1. What works/worked for you/your friends/whoever you read about on the internet may not work for everyone. That's because when talking to each other, neither party has the full picture. Neither party knows exactly the level of activity and food habits of the other.

"I simply cut X calories from my diet and it worked!" -- yes, but you also forgot to mention you bike to work and back home every day.

2. Calories in != Calories out. CICO is an approximation, a pretty good one in terms of nutrition, but different foods break down very differently in the body. I recommend watching "Sugar: The Bitter Truth". TLDW: It's a long presentation that talks about how glucose and fructose are broken down by the body.

Furthermore, CICO is super misleading on two levels:

- It completely ignores hunger. Telling someone "Go down to 1400 calories / day" can be a horrible idea if they don't radically change their diet. It's not just about cutting, it's about replacing. There's high-calorie-budget things you can't keep eating/drinking, and low-calorie-budget things that make you feel fuller that have to be introduced.

- Metabolism matters. As I was saying further down in the thread, depending on your metabolism (influenced both by genetics and overall activity level), two people may burn different amounts of energy, both when they're active and even passively by merely existing.

So, for all intents and purposes, yes, calories in == calories out. But that's not the only thing that matters. Get your diet sorted out, get your exercise plan sorted out, find a strategy that works long term (not just a crash diet) and that is and feels comfortable. Anything that is uncomfortable/unpleasant is not something that can be maintained long term.

Also, like the post says, get a digital body scale to start recording your weight. I got a Nokia Health smart scale which gives me graphs of my weight automatically. Being able to see the trends is the most critical tool. Can you imagine getting good performance at load on your servers without instrumentation, merely by just running top once in a while?

Wikipedia is terrible at teaching.
The best way we know to think of it is in terms of variance of the gradient.

In a hard environment, your gradients will be very noisy — but effectively no more than linear in the duration you are optimizing over, provided that you have a reasonable solution for exploration. As you scale your batch size, you can decrease your variance linearly. So you can use good ol' gradient descent if you can scale up linearly in the hardness of the problem.

This is a handwavy argument admittedly, but seems to match what we are seeing in practice.

Simulators are nice because it is possible to take lots of samples from them — but there's a limit to how many samples can be taken from the real world. In order to decrease the number of samples needed from the environment, we expect that ideas related to model-based RL — where you spend a huge number of neural network flops to learn a model of the environment — will be the way to go. As a community, we are just starting to get fast enough computers to test out ideas there.
Yep. They’re effectively the same in the end.
Games have become increasingly more expensive and take much more time to develop. Especially with the new trend of having games be open-world or near open-world there's a lot more time that needs to be spent making sure the player can't break the game. That's at least in the AAA environment, and there's also been a pretty large decline in single-player based games with the rise of battle-royale and moba style games, there's a lot less churn going on. There's been a large spike in indie development though and with Steam no longer curating their store there may be even more lower price point games entering the market which could be good and bad as finding the true gems that can stand the test of time will become more difficult.

>> One has been marketing that damages its own brand, particularly the "Atom" phenomenon. Intel had such an obsession with phones that it just had to make x86 processors that were too weak for phones, never mind anything else, full of bugs, etc.

I'm not sure the low power offerings from Intel were the problem. They kept wanting to enter the mobile market with bloated software from Microsoft. It's not enough to make low power hardware, the software had to be there as well.

Well, since the problem of even figuring out if you are alone is nontrivial why would you opt to do such a astronomical operation because of a hypothetical? We most certainly would not.
Absolutely, pretty much anything I could think of doing in a slow cooker would be better off done in a pressure cooker, for about the same time investment from me.

Sous-vide much more specialized, but I find super useful not for saving time, per say, but being more flexible about it. It's great when you are doing other things at the same time as cooking dinner, i.e. - leave the steaks another 30 min while I do this chore? no problem....
It's because integration and disintegration is all cyclical, as per Clayton Christensen (Innovator's Dilemma fame). When you have a new type of product you need integration to squeeze all of the performance out of it. When the industry is mature, you need to disintegrate it so benefit from outsourcing, economies of scale, customization features for customers, etc.

Of course the devil is in the details, so you have to figure out when to do that exactly. Do it too early and it could be your downfall. Do it later, and the same could happen.
Beating kids and giving them candy is way on the extreme side of reinforcement. Having good grades be praised by teachers/parents and bad grades be associated with disappointment is already pretty good since humans are highly receptive to other people's emotions.
I really like the idea of dev-related video portal. However, I'm running into key UI/UX issues on this website -- poor design and usability makes it very difficult to use the site. Hopefully, we'll see more iteration over time. Some suggestions that might be helpful:

* Is there an option to sort the videos based on date? Or filters? I don't really want to see older video from 2014, as some are really outdated videos.

* The title of video is really hard to read, when it's white text (all upper-case) on light blue background. I really really had hard time distinguishing one video from another. Also fonts used on the titles are the similar to meta-data, so it's really hard to find the title of each video.

* Is there a special reason why thumbnails dithered? It makes it hard to see them. If you don't want it to stand out, perhaps lower the saturation,... but dithered thumbnails are really an eye-sore.

* As someone had mentioned, having a "watch" button is a really poor choice, especially on mobile device, where button is really tiny and hard to press.

* Language tag should be disabled, until it has been fixed or made accurate. I see hundreds of videos, yet only few are actually tagged as English.

* The dimension of playing video is small; in fact, it's as big as the size of the thumbnails of related videos. Please make the video bigger.
Models like these only work when considering the order of magnitudes as a feasibility assessment. If you can determine a component reasonably has such a low probability that it pulls the entire thing down to infinitesimal probability then that observation is useful. However if the bounds of accuracy are too wide its not useful, this would be more useful with bounds.

People say that but usually the truth is the second or third book is the "best" (regardless of which book) but really it's because the material sinks in after multiple itersations, other worse because the material feels familiar even though the student hasn't actually learned to solve problems, they've just memorized bits.
I use https://openpaper.work/en/ - the direct scanning feature doesn't support duplex (yet) so I additionally made a small wrapper script around SANE's 'scanimage' command to scan, which also directly pipes it into Tesseract 4 (OCR). The result is a pdf file with an invisible text layer.

I then import those pdfs into paperwork in bulk. It has a label system and learns to apply labels correctly, which isn't 100% accurate but rather helpful. It also has rather quick fulltext search, which is nice. All in all, paperwork isn't perfect but it does the job well enough for me.

As a scanner, I got an Epson ES-200 (DS-310 in Europe) from Amazon Warehouse Deals (the packaging was dinged, which apparently justified a 35% discount).

I keep around the originals in a big chronological pile, rotated yearly. If I ever need an original document, I can search for it in my digital archive and find out its date. Then I can binary search for it in the pile.

The annoying part is scanning all your old stuff. Even with a fast feed scanner (mine is about as fast as Tesseract can process it in simplex, and twice as fast as the OCR in duplex, making my CPU -- and not the scanner -- the limiting factor), it just takes a lot of time.
yeah, putting a LSTM hidden state into communication channel seems to be the most expressive way to build up team work.

Fewer, or have some spare to cater for growing population. Farmers currently growing grain for animal feed could grow other things instead. Veg perhaps?

We're now just guessing how easy or hard it is to swap these wheels. It might be that the replacement mechanism was reinvented as well so it's easier to swap than a standard wheel. But equally you might be right that there are more parts to unhook. Either way it is just guesswork.

Find or start a weekly meetup.com group for something you're interested in. Go every week. Within months you'll have friends. I've done it in a couple cities now and it works great. Any adults who are new to your city are in the same boat -- it's hard to make friends, but this plan works.

Why Your Startup Needs Serverless Slack Bots
I didn't miss Buffett's message, because the only message he delivered through the bet was that a fund of funds underperforms the S&P 500. We cannot logically extrapolate the bet's conclusion about the aggregate industry to a conclusion about any particular fund; each fund must be examined on its own weight. There are plenty of fund managers who are worth the fees they charge, and drawing conclusions about their individual performance based on the aggregate performance of the industry is silly. Buffett didn't make any claim about individual funds.
As former military, I also concur. There is no time to read a manual or tinker. It must be simple so that anyone in the field can adapt, improvise and overcome. Or at least, quickly limp away from harm. Also, the H1 already breaks enough without adding more crud. I had the H1 wagon and replaced damn near everything on it. I can't even fathom taking that nightmare apart in the mud. CTS and runflats were enough fun.

It's a beach. Presumably the part she jogged along is underwater part of the time due to tides and that is why there is no marker.

BMI is not a percentage. The unit for BMI is kg * m^-2.

Ancestor post was referring to either percentage of total body mass as fat, or percentage of lean mass. Both are dimensionless, as kg/kg cancels out.

As such, if the 12% was % of lean mass, that would be 10.7% of total body weight. If it was 12% of total body mass (more likely), that would be 13.6% of lean mass. Either way, that's classified as "very lean".
My impression is that if you sell something of higher value, the scammers come out in droves. I tried to sell a DSLR through them, and the same scammer kept winning the auction and it took weeks to get out from under that bogus bid. I ended up selling on craigslist. Yeah, I had a few scammers, but they are easier to identify on CL, IMO.

What does "At an ion temperature of about 40 million degrees" mean?

How does "ion temperature" relate to "regular" temperature?

Is it similar to how we can cool down things to fractions above absolute zero, by using lasers to reduce the movement of atoms? i.e. is the "ion temperature" a measure of how fast are they moving, as opposed to the every-day meaning of temperature as "how hot something is"?

I realize that "how hot something is" depends on how fast the atoms of said "something" are moving, but since they specify "ion temperature" I'm guessing it has a very specific meaning.

I searched for "ion temperature" but only found about Electron temperature [0].

Could someone explain it to me in lay terms? :)

How much food do you think a cow eats? How much fertile soil is dedicated to grow food for livestock instead of human food? Is it safe to say that a cow eats about 50kg per day? How much do you eat in a week? These are the things that you should be asking to yourself.
I get that it's more difficult to do such changes the older you get just from a psychological standpoint, especially if your body is used to a caloric surplus (which it probably is if you're thinking about going to a 500 kcal deficit). But I'm interested in knowing if the body metabolism really changes so drastically when you get older as to make a -500 kcal diet impractical, and where the cutoff for practicality would then be.
It would be very interesting to see and Intel or AMD designed RISC-V chip. I'm curious just how the ISA could do given similar resources brought to it.

AMD should be in a better position to try because they were already planning to put ARM cores in their SoCs a few years ago. While that effort was dropped, I assume they still have a bunch of people around that know what the issues are and are ready to tackle them. Problem is ARM doesn't really have enough of those people to divert to alternatives.
How to Create an Augmented Reality App for the Vive Focus in Unity
The 'desirable state' always exists and that is govern by the laws of physics and the environment.

In this case if we have self replicating proteins in a puddle of amino acids then those which would replicate the best in that environment and that process would be governed by multiple factors such as what is the most "cost effective" combination and what is the most "resilient" combination that will hold up to environmental factors.

For the amino acids themselves it's not that different which ones would appear and at what ratio would also be governed by the laws of physics based on the compounds available, the make up of the solvent existing energy sources and more.

If for example you have amino acids that can survive dehydration and those who cannot then the only ones which will be left after a few cycles of that puddle drying up and filling with water will be those which can survive.
Same will go for the proteins the protein which will be able to survive dehydration the best and or the proteins that would assemble and self replicate the fastest during the wet period would be the ones that are the "desirable state" as these would be the ones that survive this specific environment and process.
I haven't done much compared to some of the others in this thread, but I've done a few home automation things.

Using Phillips Hue light bulbs with the Hue API, I created a PHP script that automates a number of lights in the house to perform different actions at different times of day.
A light on my nightstand does a slow fade up for easy waking in the morning and then switches itself off about an hour later once my wife and I are long out of bed.
There are also a lights throughout the house that flip on at sunset and then switch off at different times later in the evening, signaling, hey, it's time for bed.
Yes, I could use a smartphone app (or apps) to do similar tasks, but having direct control in script form is so much easier. Changing times or adding a new bulb into the system is just a matter of editing an array in the script.

We also have a terrible time with water leaking in the basement. The sump pump we have does push out water fairly well when it runs, but it gets overwhelmed easily. Plus, the float doesn't always work correctly, so water can collect in the pit without the pump switching on like it's supposed to.
So, using a combination of a TP-Link smartplug, a Wireless Tag water sensor, IFTTT and another custom PHP script linking to the TP-Link API, I now have a system that keeps water out permanently.
This particular sump pump has a manual switch that allows it to run, bypassing the float. I leave the switch in the ON position and plug the pump into the TP-Link smartplug. Then I mounted the Wireless Tag water sensor in one of the basement drain pipes.
If the water rises high enough to trigger the sensor, IFTTT triggers the TP-Link plug and the sump pump runs. Once the sensor no longer detects water, IFTTT again sends a signal to trigger the plug so that the pump stops.
Along with this method, using PHP with the TP-Link API, I monitor weatherundergound.com every 20 minutes and if the current conditions show any form of rain, the script switches the pump on, lets it run for 10 minutes and then switches it off. Just long enough to keep the water level from rising too high.
I connected all these water prevention items up a few months ago and haven't had even close to a wet basement since.
(Oh and, why not just get a better, working correctly pump? The pump was apparently put in by the city years ago, long before I moved in, and is a cheap "torpedo cylinder" pump. Our plumber said it would take $thousands to tear up the basement floor to install a correct pump and the pump can't just be replaced because no one makes the type of pump any longer that would fit in the current pit. So going the automation route just set me back about $100.)

https://www.stavros.io/posts/building-cheap-home-sensorcontr...

I used an ESP8266 with cheapo sensors, the whole board costs like $5 or something. The software is pretty ad-hoc but is not more than 100 lines of code.
Back of the envelope:

One car weighs ~3500 lbs. If I keep 35psi of air pressure in the tires, that works out to ~100in^2 of contact patch. With four wheels, that's 25in^2 per wheel or 5in square.

This looks like the tread-extended contact patch is more like 12in long times the original width, or 60in^2. That halves the weight per square inch.
Happy to share my experience with ebay.de in Germany as a seller and buyer.

Started selling some old tech/appliances I don't need anymore on eBay: last month 4 items for 250 EUR total, before that a few more items for ~400 EUR total.

Items went for 50-70% of the original price, and then eBay took their commission which at times was quite steep at ~15% of the selling price. It was still worth it since for most items I couldn't find any takers locally on Kleinanzeigen (Craigslist analog).

eBay has annoying limits for new sellers so to sell my old Sony camera I had to wait a month after selling my old Canon DSLR. It's impossible to contact a human support for this issue. They raised my limits automatically recently though.

Don't remember any problems with my buyers or when I bought something. Some of it I shouldn't have bought at all but that's a different story :-D Looking forward to clearing more of those storage boxes.
Eating out isn't nearly as difficult as you're making it out to be. There are plenty of foods you can order where you can fairly accurately assess the calories, once you you get good at it. Once you weigh enough food you can start judging portion size, e.g., that looks like 200g of rice and 100g of pork. And you can taste how oily or how sweet something is.

You can definitely taste if a chef is adding 5 extra Tbsp of olive oil to 1 portion.

As long as you're weighing yourself and tracking calories, you'll know how accurate your estimates have been and you can adjust accordingly.

For restaurants that are listing calories, they might not always be accurate, but over time they should average out.

Also with fast food and fast casual restaurants, food assembly is so regulated, you be even more confident in the calorie count.
I think the same. I ate meat for for 33 years but I changed so I think that if the change is there maybe the humanity is gonna move that direction.
