Echoing TheRealSteel's comment: IF with a reduced carb diet has worked for me and was easy to adapt to and to follow.

That last point is the key: it's a lifestyle change, not a diet, so you need a regimen that is acceptable enough to actually make it a daily routine.

Fasting for a day or three is worth exploring as well and is much easier to do if you're already doing the aforementioned time/carb restricted approach.
Do we actually know whether these effects are triggered by calorie restriction in general, as opposed to restriction of some specific nutrient that's happening incidentally to the calorie restriction protocol? I seem to remember some reports from ~10 years ago that protein restriction, and possibly even restriction of specific amino acids, has shown similar effects.
Frugality is one of Amazon’s leadership principles. The flight class restriction is consistent with that. It helps them keep doing things like building new things and lowering prices for customers.

There are other ways Amazonians get rest, like flying the day before a meeting and staying in a hotel the night before. And even with the added hotel and meals expenses, the total cost is often cheaper than flying business class.

Again, just my opinion, not speaking for Amazon.
I agree, there's different strategies for different scenarios. However your 3 scenarios don't take into account highly active people who are in shape. When losing fat, I ate less carbs, and did intermittent fasting. But once I had built muscle and kept exercising I need those carbs as short-term energy.

Carbs are fuel, if you're not exercising you don't need much fuel, and can probably run on your fat reserves. I'm on a high carb, high protein, low fat diet now, which wouldn't be viable if I stop exercising.
What I find interesting about InstaAds is that whatever product you find advertised is likely garbage... whether it is or isn’t you can find it (at the same or higher quality) for 50% off by searching eBay/Alibaba. It’s almost a joke now. Maybe I should make a meme and post it to the Gram.
Ask HN: How do you manage text in software projects?
Dealing with text in software or web projects is always a mess: the customer needs a process for changing and approving content, labels, button descriptions, etc. and we always end up implementing some sort of custom process in Trello, Jira, et.al. The result does not integrate well with the code tools we have.

PO files work well for software but don't really interface with customers and approval processes. Adding localisation into the mix makes it even more demanding - now we have to keep track if the original text changes so the translations get updated.

How do you solve this?

Another upside: you'll never be stumped implementing something in Javascript/TS. There is no lifetime management. And the entire ecosystem is async-everything. You aren't stuck in an async-ready subecosystem like you are in Rust, Python's Twisted, Ruby's Event Machine, etc.

Why designers love other people's problems (Stripe Sessions 2019)
That's seems like outdated info.
At each of my last 3 jobs I've been a strong advocate for tracking knowledge in a Wiki. We've used MediaWiki and Confluence, and both worked well. It helps if everyone does their part to contribute, which doesn't always mean everyone has to write. Some people can dictate what they know. Some can provide screenshots. Sometimes just getting someone to leave a comment with a correction is enough. I like to start with stub articles and allow them to grow organically, without harping on folks about it.

Often there are many ways that changes are communicated (for example, an email to the NOC team to advise of systems being decommissioned, an email to the helpdesk to advise of new support procedures, etc). To some people, that email is the documentation. I know that if I want it captured in the knowledge base, that email is my cue to transpose the notification email into documentation that can be referenced later.

My current job is doing sysadmin support for a consultancy, so there are lots of clients and lots of other people doing this work. We have a regular pager rotation for emergencies, so if you get an overnight call to work on something and can't find the information about it, you start to realize how important the docs are. That has been a big motivator in getting people to update docs about the things they know. If you don't want a call overnight, make sure there's nothing that isn't in the wiki!

I use plugins to help point out when content might be out of date, and guide people to archiving out-of-date docs, or to update them. I regularly refer to Stewart Mader's great book Wikipatterns and its list of patterns/anti-patterns to help with wiki adoption and behavior. http://stewartmader.com/wikipatterns/ The book is a great read and covers a lot of your questions, especially skeptics and opponents, and how to address them.

Complex numbers exist just as much as the Euclidean plane. Furthermore, they are also scalings and rotations of said plane.
I think you’re taking the term “purify” too literally. These are just filters meant to reduce the concentrations of dust and other particulates. Nobody is expecting to create like, a microprocessor clean room with these.
It doesn't. There are cheaper cars that don't skimp on these things.
> “ It turns out if you agree to take on the risk of cancellation”

This is a common fallacy that we can use the pricing mechanism to account for the risk. But whether it’s food poisoning (cheaper prices for expired goods), labor externalities (cheaper prices for goods made with slave / child / exploitative labor), or geopolitical risks (cheaper prices for travel that can be cancelled for reasons that regular citizens simply cannot adequately prepare for), across the board it’s a failed idea.

The information asymmetries and burdens are simply too lopsided against regular consumers. Pricing as information aggregation (thus reflecting correct understanding of risks impounded in prices) is not a thing. It is theorized but fails to exist.

And risks of insolvency are far worse for individuals than for corporations, on multiple levels.
Just 1.5 generations ago, University was for those who could afford it. Many grad student programs today are in that category. This category of people competing for jobs otherwise filled by individuals with wealth will always exist, there's no 'solution' to this problem.

I think it's best to not take those jobs and to find a cost-efficient way to get through grad school. If people did this, the system would change. There are many ways to access less expensive education, you don't need to be on the coast of California. It's obviously 'too expensive' and that's a real and fundamental issue in life.
I would rephrase your approach based on what technologies you know and want to work with.

Instead of looking for project who need help, why not:

I know $technology, which projects are looking for help?

It's then a matter of a couple of web searching sessions. :)

BTE, almost all scientific projects are looking for help. It's a matter of fit.
I even once got a `!!!someVariable` in a codebase I inherited. It's what convinced me that the previous devs weren't doing weird things to work around a bad backend: they just didn't know what they were doing
I think a lot things have changed since that recommendation. And maybe your doctor has not kept themselves up to date with the new research. I am particularly referring to "don't eat breakfast is destructive".

IMO, nutrition is such a complex topic and I feel like we have only begun to start peeling the layers.

As an aside, did you know that the saying "Breakfast is the most important meal of the day" was invented by the founders of the Kellogs cereal?
I've done strict calorie tracking for restriction, keto as well as IF.

The best I've ever felt was keto, the easiest for me to adhere to was calorie tracking. It's marginally harder if you eat out a lot, but if you cook for yourself and can throw everything on a food scale for a week or so until you get an idea of what's servings of your most commonly-eaten foods looks like, tracking calories made losing weight for me and reducing my daily eating almost comically easy. There's a switch in my brain somewhere that works really well when I have to enter the calories of everything that goes in my mouth into an app....suddenly that cookie or those chips that were so hard to resist aren't a thing for me at all....my brain manages to yell "200 calories for THAT?? Nope." I found myself eating more at the end of the day just to hit my total calories and macros.

You wrote a great tutorial, I'm definitely saving this and sharing it with any colleagues who need help with command line file mangling.
Yes, that is basically correct, but I think your assertions that "you cover all the cases" and "valuable in catching bugs" are not correct.

For example, in C, you can define a Union type that can hold either a string or an integer, declare a variable of that type and initialize it with a string, and then simply assert that it is an integer.

I think that with your assertion of "valuable in catching bugs" you are referring to Sum Types (often called tagged unions). For Sum Types, if a language supports this concept, it usually also forces you to cover all cases at compile time, whereas with plain unions, you can shoot yourself in the foot, if you're willing to do so.
Yes not so useful for small images but when users view multi-megabyte images then I guess the savings will start to be significant even with the page overhead. Say a 4Mb image can be optimised to 2.5Mb then total download comes down from 6.9Mb to 5.4Mb which is not trivial, especially when the same page has multiple images (some people upload a gallery of images on sites like imgur) or when viewing lots of image URLs. Especially on a limited data plan these small savings will start adding up.
I'm not sure that qualifies as a sunk cost fallacy. Most people have limited budgets for vacations. If they already booked a trip to someplace and cancel it without a refund, they may not be able to afford going somewhere else. On the other hand, if they haven't booked anything they can go somewhere that's of perceived lower risk or just hold off for the time being.

AOL used Community Leaders to moderate chats and forums. The CLs filed a complaint with the Department of Labor for violations of the Fair Labor Standards Act (FLSA) and eventually sued, winning a $15 million settlement.

It's a violation of the FLSA to use volunteers to do unpaid work at a for-profit company, even if the volunteers are OK with not getting paid. It's only going to take one mod to file a DoL complaint before Reddit scraps all the mods or centralizes the mod duties under actual employees.

Pricing Strategy for Your SaaS Business
If you’re looking for an air purifier, the Honeywell HPA300 ($200) is more than enough four our three bedroom house (despite the 465sq ft rating).

I want to be able to recommend the Bissell Air400, as it is quieter, has a built in PM 2.5 meter, auto adjusts to pollutants, and the filter works at least as well.

Unfortunately, it randomly turns itself off. This seems to be a design flaw, as many other people report the same thing. Also, it doesn’t seem to use a PID control loop to set fan speed, so the automatic speed controller sets itself far too low for our house. On the bright side, it is frequently on sale for 50%+ off, since it has a terrible reputation.

In practice, I leave the honeywell on, and use the bissell if there’s a problem (cooking smoke, allergies, wildfires, etc). In tandem, the two are able to lower PM 2.5 by over 90%, which is more than enough for fire season.

Edit: In hindsight, I would have bought the HPA 300, and a standalone sensor like the ones from purple air.

The BBB's NAD program didn't conduct these tests this because of ordinary people questioning the claims, it's doing it because another business demanded it (and paid for it).

When it comes to dealing with consumer complaints, the BBB's goal is to make its members look good and keep them out of civil lawsuits, regulatory investigations, and media reports. They want to minimize damage to paying members, and will do things like removing bad reviews from its websites (this personally happened to me).

I don't think the motive is to make it easy. I think the motive is to make it highly profitable for someone.
A couple thoughts:

1.) communicate asynchronously as much as possible. If you have a synchronous conversation like a meeting, make sure there is a written representation of what was discussed. If it doesn't persist, it doesn't exist

2.) Understand that implementing a wiki by itself will not work. There's a gravitational pull to throw a bunch of junk in it (like a file cabinet). Things become out of date and each person will structure things in a different way.

3. Create some loose structure around sharing regular, written updates about what each person/team is working on.

At my company (https://www.friday.app), we've created a tool that is somewhere in-between Slack and a wiki. It's kindof like a work journal. As a distributed team who only has 1 meeting every week, it's a place where all our updates are captured in a single place.
Ask HN: Are you paying for access to a private community? Why?
I'm trying to understand paid-for and private social networks and communties and would like some input from those who use and appreciate them.

What communities are you part of? What makes it worth the money for you? Why not just use free alternatives like Reddit or FB?

I'd really like to understand this because it's such a foreign concept to me - I don't think anything could convince me to sign up for something like that, yet loads of people do.

Any thoughts?

>Residents get a tax break because GF food tends to be more expensive.

Not exactly a tax break, people affected can get some gluten free food for free, according to a rather complex authorization process with a limit of around 100 € per month, some reference:

There used to be a tax break for a few years, but it has been cancelled currently.

No.
Only if there is a suspect of the kid being affected, and the procedure is not completely free.

But yes, generally speaking there is a lot of attention to the issues that someone celiac may have, even in (some) churches you can have gluten free (actually low gluten) communion wafers:

EV Start Up Searching for CTO and Data Scientist
Parking Eagle is a two year start-up focused on EV route planning. See our pitch video below

https://www.youtube.com/watch?v=hRxrjexIXsY

We won a Global Start up competition with Engie in 2019.

https://www.forbes.com/sites/trevorclawson/2020/01/16/its-not-just-about-the-carsfilling-the-gaps-in-the-electric-vehicle-ecosystem/#2322cf5c150e

The descriptions below are meant as guides. We want to work with people who have a zest for pushing forwards the transition to mass EV adoption.

Roles

Data Scientist Co-Founder
To work primarily on optimising algorithms related to electric car route planning. Optimising the routes based on user preference for stopping (e.g. coffee, gym etc) and vehicle type. With a goal to ultimately providing coverage for Europe. Looking for someone who has been senior operations research professional, with a background in applied math, stochastic modeling, queuing theory, machine learning, scheduling, simulation, and optimization. Has had experience in industry, developing analytics solutions in across multiple domains, including for example telecommunications, healthcare, cybersecurity and applied cryptography. Must be comfortable with AWS, Linux and OSRM. Happy to discuss all backgrounds which could fit, the above is meant more guidance.

CTO Co-Founder
As we bring in more partners, we are looking to integrate multiple APIs and data vendors. The CTO’s role will be to set out the core foundation for the data architecture, which will be the bedrock for future success. Currently will be a lead developer or have significant development input. We are not looking for someone to do just architecture, we are in build mode. Familiarity with HTML, wordpress, Restful APIs, Node.JS, Python, App development, database architecture and design. We will also collect data, with a view to generating interesting insights on how to optimally design the charge point network and increase utilisation of EVs across the system.
> It seems at least the Linux folks optimized the crap out of clone() over the last years.

The most essential Linux benchmark is compiling the Linux kernel (since it's something the Linux kernel developers do all the time, so they really feel the impact). The clone() system call is used both to create new threads and to create new processes, and the Linux kernel compilation uses a large amount of short-lived processes (each C file is a new C compiler process). It's only natural that clone() is heavily optimized, together with the filesystem caches (each new C compiler process reads the source code files from scratch).
Its often the case that less technically minded people move into management.
At FAAG its well known that some AMD procs are faster, cheaper and cooler(well higher performance per watt). None of that is in doubt, what they are having trouble with is supply.

It appears that AMD are not able to provide either the support (microcode tweaks, firmware heads up, firmware testing and bug reporting) or the volume to be useful.

The conclusion was that AMD want to nail consumer first.
You're already paying for the service. The service improves because the business providing it has to stay competitive to keep getting payed.

A business is not obligated to improve a service just because you donated your telemetry data.
Compressing improves disk's bandwidth
So annoyed I bought one of these based on testimonials from people I trust (podcasters with allergies). I haven’t seen a significant improvement over a regular HEPA filter.

At least it looks cool and has a HEPA filter at the base. It just doesn’t move that much air.
> it's a feature that's very much out of favor at the moment.

I'm glad if it is so. Exceptions should actually be "exceptional" and not the part of the normal execution flow. Whoever has other ideas has the wrong model of what, at the lower levels, exceptions actually do.
>Molekule air filters as superior technology based on nothing more than having seen their Instagram ads.

Reminds me of an overpriced tech company that claim security but continuously gets their devices hacked.
They may still be comparable. If the point of Lepton is to save space, and if a round-trip through Brunsli costs less than Lepton encoding while saving similar amounts of space, then it could be a design alternative.

Indeed, HEIF/HEIC is basically a slightly dumbed down HEVC (h.265) i-frame (full frame) (HEIC)[1] and new container format (HEIF)[2], similar to WEBP being VP8 i-frames in a RIFF container. So they are used as full blown codecs in practice, usually not in a lossless mode, so shifting JPEG to HEIC or WEBP will lose some quality.

[1] Decoding HEIC in Windows (10) requires you to have installed a compatible HEVC decoder. Which is 99 cents (and the hassle of setting up a store accounts and payment processing with MS) or an alternative free one which will use the HEVC codec that is shipped with hardware such as newer Intels (QSV) or GPUs. Thank you patent mess!

[2] HEIF the container format can contain JPEG data, but in practice does not or only as a supplementary image (previews, pre-renders, thumbnails, etc)
