We have, but most of it seriously flawed because of many issues.

For instance this pretty serious study on diets (http://www.dishlab.org/pubs/MannTomiyamaAmPsy2007.pdf) had to rely on BMI for segmenting the subjects because the whole field had standardized on BMI. Yet we know for decades that BMI based segmentation is meaningless, BMI itself being a clunky relic of the past. Then you can come down on the subject of the studies, repeatability, no possible control group most of the time etc.

We can say that's the best we can do, but we should also accept it's far from being reliable info most of the time.

> it actually does work

well, it doesn't work or not, it's just a concept, an observation like a law of physics. It's like saying gravity works, that's not the info you'd give people having difficulties to build a self balancing robot.
I mean, they realized their mistake for other image formats, hence: golang.org/x/image: https://pkg.go.dev/golang.org/x/image

Now it's really confusing to have to figure out to import stdlib image for jpeg, but x/image for bmp.

For bonus points, check out "image/draw" vs "golang.org/x/image/draw".

I'm not sure it makes sense to look at it that way either. What if it takes you 100 calories to move 100 meters but your competitor only takes 80 calories to move 100 meters?
It's good value for money if you can demonstrate that he's creating a hefty portion of the company's value. That may well be, but I see no good reason to assume that just because he is the CEO he is actually demonstrably responsible for creating 10x the value of an average Apple employee, never mind 100x or 1000x+. What evidence exists to show that he has made the company any money at all?
When you look at the audio routing in Linux "teams" is no where to be seen. It's all "skype". So apparently they just took Skype and made it "enTeRpRise"
Most people think the fusion idea is cool enough to be enthused over, and assume all the deep technical difficulties, beyond actual fusing itself, will evaporate, because that would be cool too.

Consider that the majority of startup companies with apparently good ideas never get to market. People like to think the hardest problem they know of right now is all that matters, but often it is a boring problem that sinks the company. Maybe it is technically solvable, but costs enough to destroy the value proposition.

So long as solar and wind costs are still falling fast, any prediction about the viability of competing tech is at best provisional.

Solar and wind benefit from the opposite effect: there are known problems, but they have lots of known viable solutions that are just competing for which ones (plural) will end up cheapest, or have the most side benefits, or are easiest to deploy.

It used to be that poor round-trip efficiency would sink a storage technology, but generation has become so cheap that losses matter less than other considerations. 50% loss? Build out more panels!

Hydrogen still has awful efficiency, electrolysers and fuel cells need platinum-group metals, and liquid hydrogen needs really rigorous handling, but H2 is so useful that those don't matter. Efficiency and cost will only improve. Ammonia synthesis is similar: super-useful, but maybe easier to make starting with water. (There will be a lot of waste oxygen soon.)

Iron-air batteries likewise have poor efficiency, and low discharge rate, but the material basis is very, very cheap. You can gang up thousands in parallel to get the rate you need, and stick lithium or lead cells on the front to handle load spikes. Useless for cars, fine for utilities.

Liquifying air is very mature tech, so as the basis for a storage medium it's a safe bet. Storage capacity grows with cheap tankage. And, excess LN2 is valuable, so when your tanks are full you still have revenue.

It turns out there are myriad elevated basins that would be perfect for pumped hydro storage, another very mature technology. Unlike hydro generation, you don't need a whole watershed and river valley, just hills with a dip.

Even if fusion fizzles for utilities, the mostly-aneutronic sort might be perfect for outer solar system propulsion, where a completely different set of constraints apply. And, military deployments will often not be able to lay out much solar where they land. So, even though fission is, relative to solar, super-expensive, places can be found where nothing else will do.
From a quick skim of search results (e.g. [1]) it sounds like it’s unlikely (although not impossible) that they’d be reading private Slack messages as it usually requires a request to Slack who will ask for appropriate employee or legal consent. Of course this could be much easier to achieve (or avoid needing) than it sounds, I have no experience of this.

It wouldn’t surprise me if it was more likely that they were either told about the chat by someone, or perhaps saw it over someone’s shoulder or whatever.

Still, it’s good advice to treat what you write on there as something that could one day be read by someone unintended for sure.

I think the debate has been settled a long time ago:

News skews negative, but you purport to combat that; the headline mood should align with your goal.
>By the time the other party learns they have the 5-day retention, it's too late.

Anyone hoping to use this trick to pull off the perfect caper will be dismayed to discover that not only is the other party allowed to talk to your employees, human testimony is admissible.

The idea of trying to make the past go away after five days, by deleting the digital records, reminds me of https://xkcd.com/1494/.

I'd also like to point out that this thread - where we're discussing the pros and cons of a technique for getting rid of inconvenient records, is itself the kind of awkward talk that, if found in a Slack channel during discovery, would turn in to something else entirely in the hands of some other company's lawyers. That sheds an interesting light on these retention policies.
I've never coded. I'm a boatbuilder and marine architect (that's a very specialized kind of hardware engineer in startup language). We have "coding problems" too: how to make a boat so it doesn't kill the people who take it out to sea.

Different parts of a boat need to do different things, and often your next boat can't be designed by copying your last one and making things smaller or bigger; you need an entirely new concept for a new function.

So when I sit and "think" about the problem, trying to make progress on it, I usually spin my wheels and get nowhere. I can't draw, I can't write, because I'm forcing it. Trying to make money thinking, right, and it just won't come.

But often, later that night, I'll have a fully-formed picture of the solution come into my head, of the thing that was puzzling me back in the daylight. I'll get up, turn on the light, go to my desk, and sketch the thing out, with explanation about what the different chicken scratch lines are. I put my mouse on top of it so my cats don't knock it onto the floor, because in the morning I've complete forgotten I even woke up and drew it. The next morning, there's my solution sitting on my desk.

So faced with problems demanding solutions, I've learned to just relax and be the space that the solution can come into.
Here is how I think of it. No one is as concerned with my employment as I am. I cannot control what happens in a company owned by someone else. The economy is much more dynamic than it used to be. In the USA, at least, there is no loyalty either way: from the company to the employee or vice versa.

Therefore paradoxically it is safer for me to work for myself than for someone else.

And in the case of us tech types, we have an advantage in that we can often conjure up a business out of nothing. Maybe it’s just search engine optimization, maybe it’s a website agency, maybe it’s an application that you sell. So if you are a programmer, the cost of building your business can be minimal. If you pursue some more expensive form of tech startup, you can easily get funding for it if you’re good or the idea is good. (in the USA, venture capitalists tend to invest in the person more than the idea.)

I took this approach starting in the 1970s and have been mostly self-employed since then. It has worked out very well financially. I consciously decided to put family and work life balance first, which I knew would limit my earnings. I made millions, not hundreds of millions, but that was plenty. My strategy was to take plenty of risks that I could afford, and go for consistent singles or doubles instead of depending on home runs.
Anything can generate interesting discussion. A little self analysis never hurt no one, and experimenting on yourself can teach you some things.

I'm not sure. If we're talking about turing complete languages, aside from performace, you can get all kinds of features in all kinds of languages. It's actually a matter of how expressive, safe, idiomatic and well designed they are for everyday usage.

When discussing a language which is defined by caching values, we sure do want to see how that looks like in practice.
But that goes to the other part of the fallacy, because even if you eat a pile of 10 Mars bars, a large amount of that will just get excreted. Meanwhile you'll start to feel physically sick and probably your body will then reject food for a while. CICO does more harm than good in IMHO because you're talking about a complex system.

Just a simple scan of some foods and some exercise calorie amounts and times should show it.

Reasonably tiring exercise on a bike could burn 10 Cal per minute, so maybe 600 an hour. But swallowing a few packs of crisps or a few chocolate bars could fill that right back up in a couple of minutes. If you were speed eating you could swallow it in under a minute.

Think about if your weight is steady, how long you spend eating and how long you spend using energy. It can easily be the case that you spent all your calories in 23.5 hours and were eating for just half an hour.

The time ratio is so lopsided it's hard to come up with a plan where exercise carries most of the weight loss vs just eating less.

If you think of your energy use as base rate plus exercise rate, because your base rate is sustained for the whole day you'd have to exercise like crazy for a long time to make up any difference to what you eat.
You can't flee from "Office politics", it is everywhere in life. In fact, I consider it a talent for a person to be able to judge someone's merits fairly if they dislike them. Academia seems to be very extreme on this though, because a lot of professor and admin jobs are "islands with a king" where merit is much harder to define than in a department of a company for example.
I experienced the exact same problem when I ran my web agency. So much so that I decided to quit after 20 years and start an insight management company instead (https://wecomplish.no/).

I belive that effectively collecting, sharing and reusing insight within any team requires culture, skills, tools, time and incentives.

## Culture/mindset
Helping your team understand the value of managing insight is central in order to have everyone contributing effectively.

Recommended reading for you and your team:

* Insight management (https://wecomplish.no/article/insight-management)
* Team playbook (https://wecomplish.no/article/team-playbook)
* Fix organizational bugs (https://wecomplish.no/article/fix-organizational-bugs)

## A system/structure/taxonomy
When you have the culture in place, you need to have a well suited location for storing and sharing insight.

I am of course biased towards the Wecomplish platform (https://wecomplish.no/platform) here, but I belive (like you) that the most important thing is to have a clearly defined structure/framework.

The structure of the Wecomplish platform is refined over 20 years and can be found here: https://app.wecomplish.no/overview

I belive this structure could be replicated in any insight management system.

## Skills
If people don't understand which types of insight the team considers valuable, nor has the ability to distinguish between them, they will be held back.

The quick fix for this is to have a catch-all Wiki section where anyone is allowed to put anything, and where more experienced team members can refine and move stuff to the proper location at a later date.

The long terms solution is to improve the understanding of the differences between concepts like roles, responsibilities, processes, checklists, polices, etc.

For our clients, this is usually done through consulting servicess, but basically I belive this just takes time and practice.

Printing out and looking at https://app.wecomplish.no/overview might be a good place to start here.

## Time and incentives
If a team always favours _doing_ work over _documenting_ or _improving_ work, there will never be time nor incentives to manage insight.

Make sure that insight sharing is clearly visible and celebrated within the team on the same level as deliveries in order to slowly but surely build up an insight management culture over time.

Good luck!
Fair question and good point. Our Slack isn’t absolutely quiet - we do have a channel for coordinating on customer issues (meets our urgent and ephemeral criteria) and it might be that some matters are raised by other processes outside of Slack but Slack itself is a good fit for in-the-moment collaboration. But in short we aren’t absolutists, it’s a mix of a few specific channels for certain contexts, channel-specific muting, and updating one’s Slack status - all under the guidance that Slack immediate responsiveness is not generally expected but more the exception. It sounds like a lot as I write that, but as a broader cultural norm within the company it does (so far!) support itself.

That said, I’ll pass your question on to the team as feedback, we should make the answer more clear.

Interesting. I've never thought of pre-built CLI commands as something that would be licensable. I'm not sure why; it's not particularly different than an NPM module or something, I suppose. I can't put my finger on it, but it feels super weird to me.
"You can’t outrun a bad diet" seems to be the party line among fitness people these days. Anecdotally speaking that's not really true for a lot of people. I run > 100km/week pretty much all year round (most of it on extremely hillly trails) and despite my bad diet consisting mainly of pancakes, white bread, nutella, pizza, fries and burgers, I am not overweight with 78kg at 190cm. Before I picked up running I was moderately overweight. If I can't run for a prolonged period of time, then I start gaining weight again. I've met plenty of people who run similar mileage and many of them also have pretty bad dietary habits but none of them are oeverweight. Note that I'm not saying that this is healthy (it clearly isn't).

However, I still think that there is a lot of truth to the "you can't outrun a bad diet" statement. A lot of people who occasionally go for a run are likely to overestimate their energy expenditure and feel like they have to eat a cow to compensate. I think, however, that the statement becomes less and less true the more excessive the exercise gets. If you burn thousands of calories day in day out with exercise it seems to become harder to overcompensate this every time with excess food intake.

I think the bigger issue with exercise is a mental one. Weight loss seems to be a pretty bad motivation for exercising. Most people I know who picked up running for the sole purpose of losing weight eventually gave up or they are stuck with their 5km weekend park run, which, of course, is rather pointless for their objective. 100% of the avid runners I know (including myself) don't care about their weight. I could probably lose more weight (or improve my long term health) if I changed my diet, but it's simply something that I'm not interested in. I run because it's fun and a somewhat low body weight seems to be a by-product of that.

Don't use a desktop environment. Literally run in text mode. Use Lynx/Links/w3m if you need to look something up. VLC has an ncurses interface, and you can use youtube-dl to download music. Use emacs or vim for text editing, and tmux to split the screen ( + more, but I never used it to it's full potential ) and you can cover a lot of ground.

The default setup for Slack (I think) dings you on any traffic in any channel. This is insane. Dinging on a direct message or a mention in a channel is a lot more reasonable and basically mimics the behavior of IRC.

But what if I like pizza?

The thing is, the 300 calories from rowing shouldn't be compared to the absolute calorific requirement (say 2500 calories) but the surplus. So Maybe I'm overweight because I need 2500 and I eat 3000. Thats 500 too much, but take out 300 and that's 60% of what I need to at least reach equilibrium. It makes a huge difference to how much I need to sacrifice out of my diet.
So, myObject and the list are allocated in different generations/scopes/etc, and we'd typically trip the write barrier, if we kept the program as is. Right. I don't see how it follows after, that we can avoid the barrier based on just mutability information. It is true that we can only "capture" data with the involvement of mutable objects, but I am struggling to figure out what more we can derive from mutability information. It feels like I'm missing some inference step between "the only thing that can be mutated is myObject" and "now you can run that in a loop, without accumulating garbage" and I can't think of one.

I would be more tempted as a compiler writer to delete all the code, since nothing is ever read outside the loop; but such analysis again doesn't depend on mutability type information per se, rather on what mutations occur in the program.
It's been a while. IIRC, it was from an article discussing the fact that radioactive fallout allows critical measurements of cellular lifetimes and that in about 25 years the fallout levels will be too low to do the experiments. I'll see if I can cough it up.

CUBIC is a good baseline congestion controller. It's the default one that is being used in Linux, so it should provide adequate performance for a wide range of use-cases. Plus it's not so "olde" - the specification is actively improved (see https://github.com/NTAP/rfc8312bis), and the implementation of the algorithm inside s2n-quic even lead to the discovery of spec gaps that had been fixed as part of this effort.

Like most other QUIC libraries the congestion controller is also pluggable. So if a different one makes more sense for a particular use-case, it could be integrated in the future.
