You can get a "Resting Metabolic Rate Test" that takes 15 minutes. That will tell you the base calories you need to maintain current body weight by measuring the amount of oxygen your body burns while breathing. I think I paid less than $100 for this.

You can also get a Dexta scan that tells you your body body composition, how much fat, how much muscle mass. I think I pay $70 every scan and get one a couple of times a year. You can use this data also to calculate estimated required calories, body composition, are you loosing fat/muscle and gives data to change diet accordingly.

You only need to be in a small 300 cal deficit to loose weight. If you want to maintain muscle mass and drop body fat it's better to be in the smallest deficit possible and this will also reduce hunger.

If you want to loose body weight quickly and maintain muscle that's hard! That does require a bigger calorie deficit by reducing food, and increasing activity (cardio) to burn more while getting macros exactly right to hold on to as much muscle as possible although you will loose muscle. Bodybuilders are experts at this, they pile on weight during the off season so they are in a calorie surplus so they can gain muscle then diet down to single digit body fat percentages trying to hold as much muscle as possible.

Everyone talks about loosing weight but you can not weigh much and be fat aka skinny fat and unfit. Alot of 'slim' people will fit in to this category unless they have an active lifestyle.

The modern normalized diet is terrible. It's carb / sugar heavy. There's nothing wrong with carbs you need them but people are eating far to many of them while not burning them and everything is sugar heavy which your body naturally wants to eat more of.

My girlfriend has mental health issues and over the past few years has become morbidly obese which causes bigger and bigger issues as I eat my veg, carbs, protein mainly whole foods. I weigh the quantities, look good, in great health medically etc. I eat well, 3500+cal a day as I burn it off with lifting weights and doing cardio.

On the other end she eats complete rubbish, sugary comfort foods, lots of fruit as it's good (high sugar), lots of full fat milk as it's good, lot's of olive oil as it's good for you, and now morbidly obese and still gaining, high cholesterol, deteriorating mental health yet somehow I'm the one with the eating issue as I watch what I eat as I eat mainly for performance, going to the gym after work most evenings isn't normal and shouldn't have to do it. She wants to loose weight but doesn't want to put in the work, she sees the stuff she's eating as normal, doesn't want to sacrifice them and sees going to the gym as abnormal. She's right the gym is abnormal in the sense it's replacing the active activity we used to do before sedate lifestyles but it's not abnormal to make your body exercise it in a way no longer doing sat at desks all day.
You're right, it's not an argument, it was a thing to point out, that this problem is not specific to non-democracies. The reason the example is from 100 years ago, is that we haven't really seen as serious a threat as that since then.

The closest we've had in the western world since then, was AIDS in the 80's, and I don't think the response was all that top-notch in the first few years. But then, the disease speed of mortality was much slower. We haven't really seen what a western democracy would do in a case like this, since 1918.
> The existence or non-existence of exploits isn't very interesting. The rate that users make vulnerable code is more interesting.

Yes. Exactly. Exploits having existed for a long time isn't interesting or relevant.

I offered no defence of C. Just that the point wasn't relevant to the argument, one way or the other.
Right, this is more broadly applicable than even just APIs or software.

Think about how often you blindly inserted a USB A or B (mini-B, micro-B) plug the wrong way first and had to try again. Why is the wrong way even possible? USB C's plug fixes this.

A huge improvement to railway safety was the invention of Mechanical Interlocking. It was made essentially impossible to set signals in some inherently unsafe ways. When you tried to give a Clear signal to the Express, through a junction a late running Coal Train is already crossing, the huge metal lever you're trying to move to do that won't budge because all your controls are connected via elaborate mechanical interlocking to prevent this mistake. The signal remains at Danger, the Express stops, tragedy is averted.

Yeah, the thing is - this is not my responsibility. I just tried, for the hell of it, FIVE other common routes around Boston. One was bad (35 minute weird route, when the 'correct' one is under 10 - Google gets it right), two got the destination completely wrong, two were fine.

It's not "some things are bad, so let's clean it up and fix the problems". It's so bad as to be unusable.

It's widely recognized in the risk reduction community that education, drug testing, and legalization is the best approach.

Interested people are going to use these substances regardless, as the abject failure of the War on Drugs has shown, and in the internet age there's no effective way of keeping people from finding out about these substances. If anything, the information about them is going to get out way more effectively and faster than ever before.

We need to inform users of the risks of these substances along with their benefits, and safe ways to use them. If they then choose to ignore those ways, that's going to be their choice.

Right now there are ayahuasca circles and peyote ceremonies people could join, and underground psychedelic therapists they could go to.

Hopefully, when these substances are legalized there'll be more safe places where people could go and have their experience with trained, caring people.

> That they had a bunch of school buses sitting around?

That they had an obvious resource which with proper planning (which would, of course, include lining up drivers) could have been used to evacuate large numbers of people, but which was not used at all, and was not even considered in what little prior planning the city and the state did do.

> most of them are usually part time employees with second or third jobs and probably also had their own families and problems to solve.

Um, put the drivers' families on the bus they're driving?

Again, this is the sort of thing proper advance planning will obviously take into account.
Illicit substance distribution is a massive, fault tolerant, self correcting and self routing network of individuals, you just have to know some people near the edge nodes. This is also why the war on drugs is such an abject failure.

As for this substance I've only had what was described as a "child dose" and enjoyed the absolute tranquility, some friends have had bad trips on much higher doses but as someone that isn't a fan of psychedelics and didn't want any hallucinations I loved that small dose.

I have to totalky disagree. Look at GPL, DeviantArt, Twitch, steam mods. People will labor for free for the purpose of leisure or enjoyment. While those people are in a minority in terms of population since most consume as opposed to produce with an actual skill.

I think if the culture was ingrained to gain a source of prestige based off of what they contribute for free, that would incentivize people to pursue those Nobel endeavors. But that sort of culture shift would take Star trek levels of time to get to.
I didn't know that. I thought the PLBs would have some feature to prevent accidental activation. But then, people have to pick up a phone and dial a specific 3 digit sequence to call for emergency, and the thing is abused too often, so, yeah, I believe it.

> Note that we call sort O(n log n) under the assumption that addition and comparison is O(1), just like the author did with multiplication.
If you’re trying to make the point that arbitrarily large inputs have non-constant complexity, you should be consistent.

I have been consistent. I agreed above that is buuble sort was one part of a program that you only call on elements of size up to 10 and the input
of the program, n, is something else then the bubble sort piece is O(1). But if n refers to the size of an array input into a bubble sort, then it is not O(1). Big-O considers what happens when the size of the _input_ grows. For a comparison sort we consider what happens where the _number_ of elements goes to infinity, but the elements themselves are assumed to bounded (e.g. 32 bit ints). This ensures comparison is O(1) not matter which two elements of the array you chosen from an arbitrarily large array. I don't see why you think the addition involved in a comparison sort wouldn't be O(1) as the addition addition that is required to increment pointers by 1.

> No operations on arbitrarily large numbers are constant on the number of digits, but that is not a good model for predicting actual runtimes of actual programs that use doubles. When I use ints or longs or doubles, it is not just appropriate to use O(1) for the basic arithmetic operations, it is incorrect to assume larger complexity when that larger complexity does not apply to your program.

You're describing the common situation when analysing a program is that the input of the program is some parameter (E.g. the size of an array) and all the integer arithmetic that arises during that program is on ints or doubles, so the program executes correctly _even as_ the input grows.

The key difference for this project Euler example is that there the input n is actually an integer that we do the main arithmetic on. The point of the program is to sum integers up to n. As I've explained before, if you then say "but practically we limit n to ints so it's O(1)" then _any_ function I write whose only input is an int is O(1) and the notion is meaningless.

When people shit on modern web development, it's hard to explain how responsible tools like webpack and babel have been in pushing the web forward so we can actually build what we can imagine.

There is SO MUCH we simply don't think about anymore because the tools do the thinking for us, like CSS prefixing mentioned in the article. I can't remember the last time I manually prefixed a CSS property, I've used tools that have autoprefixing built in since 2015. I just don't think about it anymore. Nor the differences between ES3, ES5, ES2015, ES2017 or a host of other things.

This means my brain is free to spend that energy in other places and that's absolutely a godsend for productivity.

Working in automation, I've made machines that check for grime and misprints on new bottles and cans.

If a country were to standardize, say, drink bottles, detergent bottles, etc, then this is already a solved problem. Just have a machine clean the bottles to wash away dirt and remove labels, then run it through some image processing software to auto detect any residue. Anything within a certain threshold could either be accepted as clean or needing an extra wash, and anything over a certain % of dirtiness or having undergone N number of washes without getting clean is sent off to be melted down and recycled.

Once it's standardized, the software is made, done, and ready to deploy everywhere without any changes (until the government approves new bottle designs). Facilities would be cheap to build. The only problem is every drink manufacturer in the world would oppose it since they can't make goofily shaped bottles with cartoonish logos everywhere.

Before you jump to conclusions, here’s a relevant quote from the article:

“Although almost all coronaviruses isolated from bats have not been able to bind to the key human receptor, SHC014 is not the first that can do so. In 2013, researchers reported this ability for the first time in a different coronavirus isolated from the same bat population.

The findings reinforce suspicions that bat coronaviruses capable of directly infecting humans (rather than first needing to evolve in an intermediate animal host) may be more common than previously thought, the researchers say.”

When the shooters moved from 2.5D sprite-based (Doom 1&2, Duke Nukem 3D) to 3D ones, something important was lost: restriction on performance many that no longer you could fight hordes of enemies, because computers of the day couldn't display them all fast enough. So, enemies got fewer, but tougher, and no longer you could experience the same sheer carnage as fighting hundreds of imps at once.

It was quite a while since I last played a 3D shooter (likely, HL2 Episode 2), so I don't really know if there is something out there that has a similar feel to good old Doom games.

I always thought of happiness to be in these final passages of Walter Pater’s book, The Renaissance:

“Every moment some form grows perfect in hand or face; some tone on the hills or the sea is choicer than the rest; some mood of passion or insight or intellectual excitement is irresistibly real and attractive for us - for that moment only. Not the fruit of experience, but experience itself, is the end.”

I didn’t like salvia; to me it just felt like the gain of all my neurons had been cranked up to the point where they started to feedback. It felt like my brain was no longer a device for thinking but was now just producing variegated patterns and noises and other garbage output. I also felt as if I was constantly trying to recover a lost train of thought, like I was thinking, hold on.. wait.. what was I doing again.. and when it wore off I felt more annoyed than anything else. Are all psychedelics more or less like that?
Sounds like a fan of House of Cards talking. I don't doubt that Xi may have "skeletons", but probably not like that. He wasn't born President. If there were any "skeleton" of that kind of political significance, do you not think his political enemies would already have discovered those after all those decades he has been a politician?
VCC[1] was a substantial piece of research from MSR aimed at supporting the verification of C (not C++) via a theorem prover. However, it appears in a study[2] of its application to parts of the Hyper-V code-base, there were some practical difficulties relating to proving performance in the developer workflow.

Still, fascinating to see work like this on real-world code-bases with established languages. You can also see very similar work in languages like Dafny[3].

Definitely not a fun way to bring in the new year.
> beautiful period before Google was reverse bought by DoubleClick

That's a beautiful way to put it. I remember those days and thing is, much of Google's reputation was built during those days, a coattail they're still coasting on today.

In those days I remember you could find anything at all in just a moment. "Information snacking" was a thing, versus "being given the answer we think you want (or the one that will make us the most money)".

"Reverse bought by DoubleClick", will have to remember that..

It is hard to express how fundamentally wrong the author is, in his definition of abstraction overhead, and his criteria for sound implementation practice.

The term "abstraction overhead" is already defined rigorously as the difference between the runtime performance of handwritten pre-specialized code, vs code that uses a more general abstraction.

So we don't have a proper term for what the author objects to, but avoiding powerful language features -- most particularly, destructors -- would be a huge step backward.

Most of us don't get the luxury of discarding a system and rewriting from scratch. Instead, we make the code we have maintainable. Each of the tools the author reviles is present in the language specifically because using it properly makes libraries and programs more maintainable. A system coded using the features wisely, well, and pervasively is more maintainable, and fundamentally better.

The alternative would be to say that systems in raw C, or assembly language, are more maintainable, which is obvious nonsense.

The experiences that led the author to his conclusions are no doubt tragically lamentable, but do not represent anything like the mainstream experience of system construction and maintenance.

I never once saw anyone throw trash on the street in the eighties. I have no idea why you would say that. If anything there were regular city cleanup initiatives mandated by schools. Warsaw was gray and dilapidated but it was definitely not filled with trash.

I also harbor no illusions how hard life was back then. I remember queues that lasted for hours just to get a decent piece of meat for dinner or some candy for the kids for Christmas. But with the passage of time and the experience of having lived in four different countries I can notice what the vision was and what they got right and what they got wrong.
