The key thing to recognize with modern Gillette cartridges is that the blades last a lot longer than the lubricating strips. For me, those lubricating strips last a couple of shaves at most but I get 15-20 shaves out of the blades.

When the strip wears off the shaves get a bit uncomfortable while that stuff peels off but then they start to feel better again after that. A friend of mine actually hates the strip so much that she scrapes it off brand new razor cartridges before using them for the first time! I think the discomfort caused by the worn out lubricating strip is a subtle push by Gillette to get people to toss the cartridge and start a new one before the blades have even begun to dull.
I'm in your club. I tried a few other ways to shave, always came back to the good ol' 3 blades (that seems to be more and more difficult to find in shops around my home)

Biggest issue with an injector razor blades (single edge/straight razor) is carry-on traveling through TSA. Apparently they want to keep a monopoly on barber studios at 30,000 MSL

Switched several years ago from cartridges to an injector blade system, and have never considered switching back.
You are (intentionally, I think) unaware of the context of this entire discussion where these are people who aren't comfortable managing their own servers. They don't know what they don't know.
They don't want to learn about systemd, sshd, users and groups, apt, ufw, and however many other things needed to run on a VPS.

You got your point across in your various comments.
An Afterlife User's Guide to the C64
Shaved head for 20+ years here. I use Gillette and get at least 8 weeks shaving daily without issue (ie. 8x7 = 56 shaves or 350% of your reported longevity). The trick is wet shaving (in the shower) with good lather (I use soap). Dry shaving is an anachronism in this day and age, save for water-scarce or highly unsanitary environments, where I prefer to just not bother.

As an aside, I'm pretty sure they are incrementally tweaking the chemistry of the blade-front indicator to break down more rapidly, which destroys the uniformity of the leading edge. IMHO older cartridges actually last longer. If you find a stash in the developing world or some other slow-moving place, buy them.
Maybe you have different numbers than I can find but all of the graphs of population growth show pretty much the same thing for India or China as they do for other countries: an almost flat increasing trend that hockey-sticks as soon as the country modernizes and then begins to level off or decrease as education catches up. The historical population of India seems large until you consider that the subcontinent is the size of Europe and then factor in the earlier start they had compared to Europe and there's no mystery left.
I've also switched from cartridge to double edged a couple of years back. Not for financial or even environmental reasons, I just find it more comfortable than the cartridge ones.
Update: Migrating the simplest possible Rails app from free-tier to free-tier didn't work on Render (deploys fail, no logs to be found), so I'm bailing out to try Fly.

To any render people reading this, it appears to have been an issue with the migration plugin and the Heroku-18 stack. Manually deploying the app worked fine.
put your feed at /feed/

As every wp site (that didn't switch it off) has a feed there it is more reliable than favicon.ico you will also find lots of feeds there not linked any place. I think many authors are not even aware they have it.

I like it as you don't have to visit the domain, you can simply point a feed reader at a list of (slightly modified) domain names and discover many precious shiny things.
You can keep a razor sharp longer by submerging the blade in a little dish/shot glass of mineral oil after shaving. It slows the microscopic pitting and corrosion from air/moisture.

As a bonus, mineral oil is a decent shave gel on its own, though it can be difficult to wash out the whiskers and gunk from multi blade razors.

Huge fan of safety razors. At least for me, razors with multiple blades would tug on my hair too much and cause ingrown hairs often (I think those two are casual)

Plus, nothing wakes you up in morning like potentially cutting yourself
Have you ever read stories written by young children? Kids learning to write have similar issues albeit with a much smaller vocabulary.

Gergely Orosz: Meta rescinding E3 and E4 offers
Hate away! As I've said before, out of hand dismissal of any publishing due to mouse models is very in fashion here at HN.

I strongly agree with you that primates would be a better model, from a cost is no object, no public opinion perspective. In fact, probably to many people's non-surprise, most primate work has been moved to China to avoid scrutiny. Last I saw at my place, primates were primarily (ha!) used for behavioral studies and nothing grisly.

I'll see your "here are the differences" and raise you a here are the similarities to humans:

* We're around 85% genetically identical to mice overall if we dump (actually controversial idea) junk DNA. This number varies on who you ask.

* Certain genes can be up to 99% the same. Your gene of interest being similar is important.

* We're both mammals. (some models are not)

* We share many of the same biochemical systems, endocrine, etc.

* Many genes for known diseases are shared. Disease similarity can be very high. (think cancer, atherosclerosis, diabetes)

* Mice can be made immunodeficient and used with human material.

* Very well studied life cycle, and measurement of health. We know most measurable parameters and their nominal ranges.

To harmonize with your idea of differences to humans here are the ones that make mice even more useful:

* Reproduce fast, this means ideas can be tested early and often.

* Small. Cheap to house, and make at scale.

* Genetically identical clones: we're better than ever at this now. This increases our ability to repeat and vet research.

It is completely standard for work to be done in mice. This constant dismissal of mouse models is a nothing burger. Animal models don't always pan out, however that's the state of the art.

I agree with you that in a no holds barred world primates would be universally better. In the US, IACUC exists because of primate experiments gone off the rails at Penn in the 80s. "Unnecessary Fuss" is the vid/incident. Video release was 83 I think? IACUC showed up 1985. This put primate work in the US under intense scrutiny and not without reason.

Oh and for what it's worth, I've never see a lab rodent's tail come back in 6 years of working with them. :) You are sending me on a new search!

>But also I've met and read some truly brilliant programmers and can't help but think they might know more than me.

I've seen a lot and done a lot in my over 20 years of building stuff. I like to think that I know some things, but I also am aware the the amount of stuff I don't know is far greater than what I do know. When I'm offering my input, I like to state it as "things I've seen in the past" vs. "what I know".
Just one small disagreement…electronic shifting on bicycles. I have had my hands cramp up on longer rides in humid/hot conditions changing gears manually. Electronic shifting makes a difference, especially when shifting a lot and you are out there for a while. Triathlon bikes are using them now as well, they allow for more aerodynamic designs because they don’t have to deal with mechanical cables anymore.
I switched to a safety razor years ago. I use about $10 worth of blades a year and just use bar soap for lather.

Quality of work beats quantity any day of the week. And at 80 hours, there just cannot be any quality left. At that point, your mistakes will cost you more. Maybe the people below you might offset your stupidity at that point.

I had managers doing 60+ hours. They were not the greatest, in fact, they were terrible.
Housing investment is a business. Buying the house is a risk, and you sink money and effort into it in the early phases, in the hope of getting profit out of it in the later phases.

If you are going to make that business unprofitable then no one will do it. People won't sign up for the risk, cost, effort and frustrations of being a landlord with no upside.

While we're on the topic, why not prevent programmers from putting their salary up? After all software is essential to society these days?
Wikipedia is can actually be a great source of high-quality mathematical exposition. It is often not the best source, but I often use it as a jumping-off point for learning about advanced topics. It helps me turn "unknown-unknowns" into "known-unknowns".
I’ve never understood shaving. Why not just buy a trimmer and trim it down to 1mm? Much more convenient, faster and cheaper. Also there’s very little visual difference - especially now that everything is remote.
Yeah it seems like with my own children good behavior is proportional to attention. They don't ask for much, but they don't like feeling like they're in my way. If I treat them decently, they'll let me do the things I need to do, and they know I'll come back to finish up with them later.

> Most of the critics of waterfall haven't actually worked in such a project.

I wouldn't say that's true.

> Most of the critics of either C or javascript haven't actually built anything noteworthy with it.

That's oddly out-of-place gatekeeping. I've built large things in C 25 years ago that didn't get finished or weren't put in production. That's enough to learn about C, at the time.

> Most of the critics of OOP don't have much practical experience with it

I wouldn't say that's true.

I read a collection of thoughts that feels like a combination of imposter syndrome (20 applications in 20 years? yeesh, that's sparse) and blanket characterization through arbitrary gatekeeping. I understand what they are getting at.

About 18 months ~ 2yrs ago, all copies of this keynote were scrubbed from the internet as part of Greg Wilson capitalizing on his geek-fame with an Oreilly book and appearances. Recently, there has been an explosion of Greg Wilson videos on youtube. Not sure how long it will last. Similar information is presented in this updated, broad presentation that Greg Wilson put up: https://www.youtube.com/watch?v=HrVtA-ue-x0 and there's a PDF and a dry, stale version of the keynote presentation that I can't find again.
The analysis excludes underlying health conditions… junk science.
I don’t want to risk sounding disgusting, I use a Mach III to shave my face…daily. Now I have a beard, so I don’t shave my whole face. Neck, cheeks … but I get 6 months to a year out of one cartridge on these. Having just replaced, I agree 100% about the lubrication strip.
The human mind is likely infinitely more complex than software that imitates any aspect of it. Just like human thought process is orders of magnitude more complex than that of a parrot.
A blade that chips is going to cause an unpredictable angle of attack. Do you want to scrape that across your face?
It’s not a conspiracy, it’s just convenience. Shaving with a Mach3 is a hell of a lot easier than a DE. Cooking with a Teflon pan is a hell of a lot easier than looking after a carbon steel skillet. The vast majority of people have busy lives, and don’t want to deal with that hassle. For those of us who do, great.
When I first got into Linux it was circumstantial. I was 11 and trying to figure out how to put "free games" (homebrew) on my console and that got me into installing Linux.

Back in those days (20 years ago) we didn't have the rich package managing ecosystems of today or fast internet access. I bought a Linux CD from a local computer store (though I called it Unix, magically the guy who sold it to me knew what I meant).

I remember trying to learn how to install things like the packages or software I wanted and being told if there isn't an .rpm then you have to try "compiling" it.

Naively, my world view was that there was a structured process for everything - the steps for compiling something would be the same for everything, one could simply learn those steps.

In my mind I imagined it was as simple as typing "make" and an install wizard would appear in a terminal.

When it wasn't that, I would go onto IRC channels and naively ask "how do I compile things". People tried to help and I guess they thought I was an adult with the comprehension of a child so people got pretty frustrated.

Makes me laugh to think of how structured I thought the world was; thinking there was a uniform and consistent way to compile software.

Even as I sit here with experience as a software engineer, compiling someone's random github project can be mind bending - especially with some of the objectively simpler yet also more complicated methods of producing binaries from within docker containers tailored to compilation.
> The problem is that "Link is reduced to a pile of ashes" should put Link into a "dead" state, and when in the "dead" state Link can't stand and be dazed.

For a cartoonish video game, that's not too far fetched...

I've seen more ridiculous things in animes and such.

That said, I do get your point, and I agree.
Hair trimmer set to shortest length will make your face like shaven 2 days ago. Costs nothing. Needs no foam, no aftershave gel, creates no irritation or red skin, just splash of water and optional facial creme. My condolences to those who must have a clean shave every day of their life.
A DLR guy let me press the horn when I was on a date once. Incredible night. He also let my date press the horn.
Indeed, there's no understanding, at all. That's of course an indication that the IQ test isn't measuring what we usually call intelligence (however ill-defined it is). But the ML approach is still following the strategy that a teacher of mine explained some 30 years ago. "It's like teaching pigs to fly and claim success because you're building higher towers."
Not directly related to the article. But I'm just glad we as a society have come back around to psychedelic's.

It was clear in the 1960's that these drugs have massive potential to help treat mental illness, but we all know what Nixon did. I was watching a documentary about it the other day and it just made me sad, imagine where we would be today with mental health treatment had Nixon not made these drugs illegal.

It seems that we as a society are starting to overcome the sins of the past. The problems mentioned in this article are real problems, but I almost look at it as a "good problem". If we're at the point with Psychedelics where our biggest issue is how the capitalists market it, I think we're doing alright.
Are Cryptocurrencies Currencies? Bitcoin as Legal Tender in El Salvador
The primitives of fine grained reactive programming seem to me more amenable to be implemented by the browser than react-style whole world diffing
Abstract:

> This paper studies the potential of a cryptocurrency to become a medium of exchange. We use evidence from a natural experiment: In September 2021, El Salvador became the first country in the world to make bitcoin legal tender, and all economic agents were required to accept bitcoin for all payments. The Salvadorean government also launched an app, “Chivo Wallet,” which allowed users to digitally trade both bitcoin and dollars, and gave major incentives to download it. We conduct a representative national face-to-face survey to obtain information on bitcoin’s usage and effects. Leveraging this data, we document how, despite the government’s “big push” and a large fraction of people downloading Chivo Wallet, usage of bitcoin for everyday transactions is low and is concentrated among the banked, educated, young, and male population. We also estimate the fixed cost of adopting the new payment technology, the importance of strategic complementarities for users, and the elasticity of substitution between mobile payments and other payment methods.

Hair density and growth rate and skin sensitivity is going to matter a lot. I use an electric razor because I don't have much facial hair and it doesn't grow very fast. But I'll relatively often get irritated skin from it and have to be careful about how I use it in advance of eg a wedding. Getting a close shave still requires maintenance of the electric razor, cleaning it and occasionally replacing the foils.

This will probably sound weird but, what is the point at which are you changing blades?

I am using mine with just water and I always make sure that I clean/ shake off everything afterwards.
My first proper blade lasted for 4 years. Then I changed just because I clicked on ad to receive free razor from Gillette. That one is already working for 2 years.

So I get that new blades are bit nicer to your skin, but as blade getting dull is gradual I never see the tipping point when I should get a new one. My skin is perfect by the way.
I use safety and very non-safety straight razors for trimming my beard. The converse of the TSA thing is also true: using a straight razor allows you to travel anywhere with a very, very dangerous weapon in your bag that nobody will look twice at. I just check my bag like a big ol grownup who doesn't need to Tony Stark it directly off the plane to get into my caravan of black SUVs.
Read "Meditations" by Marcus Aurelius. Cut off social media, gaming and other distractions. Figure out what you want and what your goals are. Figure out the things you need to do to reach your goals, and then do it (every day).
Think about it like this. There are two numbers, 1-99 choices. So there are 4545 possible pairs (since 2,5 and 5,2 are the same we ignore order). However there are only 197 sums (2-198) and only so many products (I don't want to do the math on that, but obviously a number like 60 is reached by quite a few pairs). Each time one of them says "I don't know", the other considers every sum (or product) and asks if the other person has received enough information that that sum or product they know has one unique unelimiated pair that generates it. For some pairs (1,1) both players will have a unique answer right away. Otherwise, both players eliminate from the set of possible answers any pair that would compute an answer that no other non-eliminated pair would compute. That means the next time the player says "I don't know" they were doing so with a more constrained set of pairs. Which provides more information. Until eventually they eliminate all other possibilities to calculate their product/sum.
I don't understand why people think it is so important a thesis to convince people that a person sells something to get as much profit for his product. Much as it is important to educate people of loss leaders, subscription models, brand marketing, and other newer ways profit maximization happens, they aren't really cutting edge concepts either.

I make a decent living now, and I use Harry's razors. Could I use and change the cheaper disposable ones more often? Sure. Is Harry's quality worth paying for so that I nick my face less? Very much so. I don't really need to be told they're "out to get me". I'm a big boy who can do simple price math.
Shaving is like an Inception-level hierarchy of waste and affectation. It's easy to feel superior because you ditched the biggest brands, and still be wasting your money on unnecessary and crappy products because you were tricked by marketing. Those hipster shave-by-mail clubs are not really better than Gillette. And the safety razor market-disguised-as-a-community is also full of waste disguised by hipster affectations. Specialty soaps, exotic animal hair brushes, elaborate rituals, etc. Underneath it all is the fact that you CAN buy a cheap, adequate, no-name safety razor somewhere, and you can buy cheap adequate blades in bulk with some trial and error, and you can find some combination of products that will work on your skin without going for specialty and prestige. Don't buy these things as tokens of a lifestyle, buy them for utility.
Fails the sniff test because the harms would have to be pretty massive to exceed the increased mortality of Covid given its prevalence.

It appears that this analysis hinges entirely on assuming the all cause mortality of vaccinated and unvaccinated groups should be the same and the only differences would be due to the vaccine. This is ridiculous because the vaccinated set is preferentially less healthy and excludes children.
Bitcoin Is Legal Tender in El Salvador, Here’s How It’s Going
Aside from differences in cost, do you find anything about a straight razor compellingly better than e.g. a Gillette Mach 3?

I go through Mach 3 cartridges pretty slowly, so price isn't a big concern. And I don't notice anything deficient about the quality of my shaves. But one thing I really like about safety razors is that there's zero risk of serious injury.
