> I'm not saying that every person must study these metabolic pathways in detail, but rather that the quick and simple rules and choices people make in daily life should take advantage of what is known, hopefully for a better outcome than what is currently observed.

I agree. I'm simply pointing out the fact that with the picture as complex as we know it is I have a knee jerk reaction to people going from "how to have normal BF%" to "ok, let's talk about insulin". It's the same thing with people talking about brain, attention span and productivity. 10 seconds into the discussions it's "dopamine, dopamine ... DOPAMINE"

> So in the case of adipose tissue, it does require glucose in order to store fat. The glycerol backbone for intracellular triglyceride synthesis is provided by glucose.

Yes. And? Glucose to some extent is always present in the blood. Drop the glucose low enough and brain will die. One could say that adipose tissue will always figure out how to store fat.

As we go on you reference Fung (and defend him) a fair bit. I'd like to take this opportunity to state the obvious. Jason Fung is a trained and certified nephrologist, book author, popular doctor and so on. He does not hold (to my knowledge) a PhD nor has he published any peer-reviewed studies.

Thus calling him a quack on my part was bad (I was pulling your leg a bit) but he cannot be considered a scientist either. He's an expert in his field but his books can't be considered textbooks on human endocrinolongy. He's allowed to have his own opinion but asking anybody to agree or disagree with his views without in-depth study of them is asking too much and he haven't (to my knowledge) presented them in the form of some kind of scientific paper it's not worth arguing whether he's right or not.

That being said - the link you provided on FFA is about cholesterol. I fail to see how that's relevant to discussion about FFA impact on insulin resistance?

Alas, to make my point. Obesity is certainly a multifaceted problem. Thermodynamics certainly matter, human psyche, inflammation, hormones - essentially all of that has its place. Looking from a systems point of view there's no reason (and probably there isn't one) to look for single causative agent though some certainly play a grater role.

In my experience both time-restricted feeding, caloric restriction and macro restriction work and have their place depending on the individual. Generally as a rule IF and low-carb are certainly good ideas, I'm not a fan of keto for everything.
When to pivot? (new app developer)
So my dream is to get people out of social media loops and entice them to instead spend 2 minutes reflecting on their life each day (and ultimately to go LIVE it). This was my motivation behind behind my new app, Health Curious. I'm torn because it was originally developed as a tool for health coaches, but we're seeing people use it socially with friends, which may also have potential. My question is this: how should I be promoting this? To coaches or to consumers who want to share between friends? We're one week old, and starting up promo and branding now. I'm a noob to all this, so any feedback would be SUPER helpful. Thanks :)

Two other pens you might want to look at/for are the Platinum Preppy (a very cheap clear plastic pen, intended to be disposable but which can be eye-droppered or used with a converter/cartridge) and the Pilot Metropolitan (a metal body with a cartridge or converter, about the same price as the Kaweco Sport; I found one once at a Walmart). Both tend to write very well.

My pocket-pen is a Pilot Petit 1, another disposable that can be refilled and dirt cheap.

Fountain pen ink does make a difference, but nib quality is probably the major factor.

The scariest Linux installation I'd ever done was by creating a Vitual Disk for an existing partition (you can map a disk to a virtual disk) on VirtualBox as a VMDK file, then mounting that as the root partition for a VM that booted from an SamuraiLinux ISO and installed it on the root partition. Very surprisingly, it worked without breaking anything.

I am surprised people think this could affect the servers? If they scrape 300k prices from 25k pages a day, and the crawl runs every hour from 15-22 UTC, then that means the 25k is spread across 3.5k pages per crawl. Even if the crawl is aggressive and completes within a minute that is still only 58 QPS.
Not ... really? I usually compare the Gröbner basis to generalized matrix decomposition in the sense of solving systems of linear equations. If you’re solving systems of quadratic equations, you should look into interior barrier solving methods, which generalize the simplex method.
First, they came for the journalists and nobody knows what happened next.
> If I gave you an RSA modulus in which you know one factor is chosen from a range of a few trillion primes, the public key could be broken if public.

And so public CAs are obliged to forbid such practices to the extent they're able to detect them. As a result on the whole users who try to use crap moduli get denied.

Go try it, mint yourself an RSA pair such that the public modulus is 11 x n or something easy, and ask Let's Encrypt to issue for that key in a name you own, they'll refuse explaining that your proposed key is crap. Here's a nickel kid go buy yourself a better semi-prime.

In contrast the vast majority of password protected user accounts don't even check Pwned passwords. I can sign up for a lot of stuff literally using Sup3rman as my password.

> The fact that typical user-chosen passwords are iffy secrets doesn't make the hashes secrets as well.

Yes, in practice it does.

> as you say yourself, we'd still hash if the passwords were random strings. Which turns them into non-secrets.

That works on random strings, but it doesn't work on non-random strings.

No amount of processing can magically make the non-random strings be random and so Argon2id("Sup3rman") is going to need to be treated as a secret or else any fool can just try the most popular passwords and reverse it.

This is why I like the Tech Lead on Youtube. He's now retired but he encapsulated the typical engineer playbook we are all striving for, get highly educated, get a good job, be happy. From examining his outlook we can see that there rarely is satisfaction at these high stress jobs, and that there are other goals in life that are far more wholesome.
Yeah, it's not like he walked from half a million and had nothing. He walked from having half a million more. (In RSUs, subject to vesting, not including salary).
In what way does anti-fascism imply anything other than anti-authoritarian, least of all pro-communism? This guy I linked below when trying to understand your comment even questions if it can be considered a "group" at all ( "I also question whether antifa can be considered to constitute a “group” at this point in time"), and I agree. Either way, equating far-right violence (which was responsible for every extremist death in 2018) and violence associated with antifa, for example against people like those at Charlottesville, Neo-Nazis, Neo-fascists, and white supremacists, just seems deeply disingenuous to the point of trolling.

I can tell you what they are not: they are not biased political opinions that are stated without legitimate authority. Just like obligations, rights need a legitimate accepted authority to be valid. For example, in the US declaration of independence, the founders address king george, their statement about fundamentsl rights is based on the fact that these rights are self-evident as the will of a just God , and since obviously the king's authority derives from God, his violation of these rights against americans gave the americans a right to reject king george's authority.

You maybe a secularist,but even then you still need a legitimate authority all humans are subject to. That could be a global treaty (UNDHR isn't) or something else but there simply is no legitimate authority that can implement a universal human right. As things stand now, each sovreign nation's government declares what rights it's subjects have, both as citizens and humans. Not that I agree with the way things are, but I do believe in each nation's right for self determination. But I think there is a fundamental question of why and if a nation should maintain any sort of economic or diplomatic relations with a country that has contradictory views on human rights.

It's not that I agree with China's stance on human rights, but more that the west needs to take care of human rights in it's own borders first and even then how can you support China by maintaining trade relations and at the same time claim they violate human rights? Why is the west supporting human rights violations?

It isn’t. It looks like COM, but it isn’t.
I don’t know about the GP’s wording, but there is a difference. It is possible for a piece of software to be perfectly secure against software-based attacks, i.e. there‘s no possible data you can send it that will cause it to misbehave. It is not possible for a lock to be perfectly secure against physical attacks; if nothing else, you can always break it with brute force.

Of course, even perfect software is susceptible to physical attacks on the hardware it’s running on, but that’s different.

I discovered that the following link shows my FB feed in chronological order:

https://www.facebook.com/?sk=h_chr

I thought, oh, great, this is the key to making FB decent again.

But after a while of using it, it usually shows almost nothing. Sometimes literally nothing. People are still posting stuff though that I can see with the default view. I almost think I may have triggered some sort of adversarial logic that is trying to force me to use the engagement-driven ordering.

Edit: In fairness, it could be that they are hostile to uBlock origin, either deliberately or as emergent behavior. I wouldn't mind ads in principle, normal ads like you used to have in print media, but I often get ones that are very unpleasant if I don't use the blocker.
How to push negative search results down: 4 steps to bury them
Yes, the jupyter notebook thing, rightly pointed out by you, it does give a quick feedback. One can also start writing code from the beginning in it and push a working cell into a .py file. This way one is very sure from the beginning that how the code will work. The downside of it, which I think, it feels to me that code is written in a very linear fashion.

Coming to debugger in python (pdb), in your blog you criticize using debugger to step line by line. But this need not be the case, one can jump to debugger prompt and set a break point from the prompt itself where one feels something is wrong and continue to that break point and repeat this process. So one need not to jump through each line. In such a case it works equivalently to carefully put print statements, i.e judiciously put print statements = judiciously put breakpoints, what do you think?

Anti-fascist action has a strong tradition all the way back to 1936 when the fascist getting punched was Oswald Mosely. https://en.wikipedia.org/wiki/Battle_of_Cable_Street

It's not exactly recent, but it is pretty much purely reactive.
The project description ("Install Linux over or alongside an existing Windows install, straight from Windows, without requiring to boot from external media like a flash drive or making BIOS configuration changes") reminded me of the old BeOS 5 Personal Edition installer which "installs from within Windows without partitioning" and "kicks Windows out of memory and boots BeOS in its place."[1]

In the same review, Scot went on to say: "I tested the Windows installer on several machines, and was amazed. Not only did everything work as advertised -- it worked better than I dreamed possible. BeOS has always been the easiest OS on the planet to install, bar none, but this is ridiculous. BeOS is up and running in five minutes or less, and everything is totally painless. Linux distributors should be taking notes." Sounds like someone did! ;-)

Time is subjectively more important to me than money right now because I have enough money to meet my needs and not enough free time to explore my interests. But I'd add that if you don't have your health, you have nothing.
As a sibling comment says, if you are on Android and have root access, it is very easy.

Just have a look at /data/data/appname/.

For example, this is what I copy to make backups of my contacts on my Android phone:

> # pwd

> /data/data/com.android.providers.contacts/databases

>

> # ls -1

> calllog.db

> contacts2.db

> profile.db

This is a simple way for moving data around, restoring applications, performing backups, editing your data (if you know your way inside the app).

Beware of the selinux labels if you are moving files across different devices, as recent android version now run with selinux in enforcing mode.

Just be sure to adjust them (useful commands if you need a reference: ls -lZ, chcon, semanage).

I like the author's writing style too... This seems to be as much an exploration as anything:

>I’ll be the first to admit it’s not perfect yet – some vertical alignment is wrong in a few places, Hangouts doesn’t work, and our ‘contenteditable’ support is minimal. But I don’t think these detract from the achievement – as far as I’m aware, no browser engine other than Webkit, Blink and Gecko can run full Google Mail, and these have all had over twenty years of development work on them.
Thanks for sharing your story, it reminds me of the 'golden handcuffs' phenomenon. You wrote about how true wealth comes from relationships with others. Are you going to try to reconnect with the folks from your past, or maintaining the relationships you already have? Are you going to try and build new relationships through entrepreneurship? All of the above?
oh yeah absolutely. Sorting via language or framework version would be helpful too!

I am sure it is quite a complex decision. If I had to guess they have a bunch of document storage all over the place and they are unifying it.

As others have said, you can either validate the schema at WRITE time (RDBMS) or at READ time (NoSQL). Personally I hate the during READ time because then you have all sort of data integrity fun to work through... In either case, I am sure they have a ton of reference documents that they need to store, so easier to manage 1 Mongo than 64 different weird databases.
This is a serious problem. As someone with audio engineering background I can honestly say that probably only condenser microphones (like those big Yeti Blue youtubers use) are going to do the job. Contrary to a popular belief the dynamic ones, even if head mounted, aren't the best idea.

You can buy a cheap condenser mic from China for maybe 30 bucks. It'll be fine. You'll need an usb audio interface with a phantom power to run it (another maybe 50 bucks). Or go the easy route and buy an all-in-one usb condenser mic like Yeti. There are also cheaper options available I'm sure.

But! Before your friend is going to buy something ask him to tinker with his audio settings. Even the best mic isn't going to save you if you don't have a control over your audio workflow.
That was very recent and people have been talking about antifa for years. Not to suggest it was the first false flag or whatever. But I distinctly remember people ranting about them around the time of the Virginia protests.
Myspace Is Alive and Well
I felt a lot more comfortable about the idea of "networking" once I started thinking of it as "making friends with people".

When I first tried networking, I thought that I was supposed to help other people, and then ask those people for favors. To me, that felt really unnatural. It felt like we were just using each other.

Now I see that my friends are the people who help me the most. They're people who I care about, and who care about me. So when people tell you to "network", I would just translate what they're saying as "go make friends".
Swift doesn’t make low-level control of memory and other low-level details easy.

Long-term: I feel that Swift was meant as Apple’s answer to C# and as way to retain XCode users as Objective-C became increasingly unfashionable over the past decade and Apple lost employees who could properly maintain it. Swift won’t go away, but I suspect that Apple doesn’t want to have to pay to maintain Swift while the rest of the industry gets to use it for free and port it to platforms that Apple won’t see any revenue from: i.e. Apple doesn’t want to be like Sun/Oracle and have other companies (Google) use their work (Java) for a competing platform (Android’s Dalvik).

So, I’m wary of adopting Swift - while Apple does currently support it on non-Darwin platforms right now I fully expect Apple to lose interest in maintaining first-class support for Windows and Linux at some point, just like how OpenStep was repurposed as a Mac-only when it became the rational decision for them.

Maintaining a thriving developer ecosystem and platform requires a degree of trust, transparency and a history of commitment to a product - and Apple (as a company) is the anathema of transparency.

They remind me of the randomly generated maps in Soldier of Fortune 2[1], lots of steep hills with trees sparsely placed around, and the occasional building. I think SOF2 did the steep hills to cut off viewable area to make rendering less intensive. I think that is also why the random maps tend to be very foggy.

Gröbner bases appear in the standard reference on real algebraic geometry ( https://perso.univ-rennes1.fr/marie-francoise.roy/bpr-ed2-po... ), so the answer may well be "yes", but don't ask me for the details.

What would you have happen instead?

IMHO, on an ideal platform for debate, the audience's experience of the debate should itself resemble the statistical distribution of opinions held by the debaters.

I.e., if 80% of people think X while 20% of people think Y, then comments saying Y should not make up 90% of the debate by any metric (number, word-count, above-the-fold representation, etc.) If Y did take a majority share by any metric, that'd be a misrepresentation of the debate, that is likely to cause the audience to come away with a misunderstanding of the issue.

I don't know how close we are to an "ideal platform for debate" on HN (probably not very)—but I feel like a certain degree of people reflexively downvoting contrarian opinions (no matter the subject) probably bring us closer, not further, from that point. Contrarian opinions should not be presented as if they were orthodox opinions. They should be given some representation—I'm not advocating for censorship—but they should only be highlighted in any algorithmic way, to the exact degree that they're recognized as something some appreciable group of people really believes.
Not based on the list shown in the article. The closest to a radical left article is the lowest ranked; and it's about a petition to declare the KKK a terrorist group, which is hardly an exclusively left-wing position.

I'd be much happier if someone could instead just provide a version of Smalltalk that everyone can agree on.

"Use Squeak!"

"No, Squeak is old! Use Pharo!"

"Pharo doesn't adhere to the Smalltalk standard. Just use gnu-smalltalk in a terminal!"

Never have I seen such a self-defeating community. If the Smalltalk community wants it to be anything more than a historical curiosity, I beg it to form some kind of standards committee and agree on a common implementation so that I can learn Smalltalk without worrying that I'm studying a dialect that is not mutually intelligible to the other implementations.
