I’m not taking a negative view on this knife or technology. I believe you’re misunderstanding the intention of my color commentary? “Do not need” is not equivalent to “this is terrible.”

Powdered metallurgy, to parry your point, is not about hardness but about having the most precise composition of a metal. I.e you can have better wearing 440C, better machinable 440C, etc. most of this was intended for manufacturing high end industrial equipment. For kitchen knives it’s unnecessary even if it’s cool. It’s incrementally better but like this product it’s not necessary.

Similarly this isn’t “new technology” aside from the packaging of industrial technology into a chefs knife. You can get X-Acto knife sized versions of this already. Ceramic blades came from industrial alumina production. Cool, not necessary, but nothing wrong if it’s your jam.

The classic “QVC knife” is the Ginsu knife which has a lot of the same claims/qualities from a far. It’s an implementation of pattern welded steel and when you use a microscope you’ll see its thousands of serrated edges. Their ad shows the user cutting a can and then thinly slicing a tomato. Works fine until the edge gets rolled and since it’s cheaply processed steel (lacking the points of good construction I mentioned above), that’s usually what happens. I’d expect the company this whole discussion is about doing a lot better here since they’re not trying to sell a three knife set for $29.95 with free shipping.

My point about things being easily damaged with mishandling is that most people simply don’t handle knives well enough to see a benefit from high end knives, not that they aren’t nice/better/valid/different/etc. All of that can be true and the knife no longer cut because the edge is damaged. A Ferrari is a technologically complex car but not a very good car if the tires are all flat. If this thing doesn’t have an edge it isn’t going to cut well.

This is a point they make on their own site:

> Is the knife dishwasher safe?

> Updated 13 days ago

>

> No, but neither is any sharp knife. Dishwasher detergents contain micro-abrasives that dull and chip away at knife edges. If you enjoy using sharp knives, never put them in the dishwasher!

This is actually a more strict take than I have on edge retention, but I wouldn’t complain if my cutlery were treated this way.

Like I said a few posts up, I have knives that cost several hundred dollars. I keep the cheap ones out so I don’t cry when they get lobbed into a sink with the dirty dishes. When sharp they all cut very well. The expensive ones are better at edge retention and can be made a little sharper. After a friend helps clean or cuts some cheese on the cheese board the knife that was used is dull and not a great tool, be it the $30 food service knife or the $400 Henkels knife. You just can’t cheat physics.

> The minimum salary threshold is £26k

You are wrong. For the Skilled Worker route, the minimum salary threshold is 41k per year, with some special jobs at 33.4k.

> "homeopaths" and "reiki healers"

You are wrong. There are SOC codes for things like "Therapy professionals". They give examples like acupuncturists, art/drama/music therapists, chiropractors/osteopaths, nutritionists, sports therapists/massage therapists. No "reiki healers", though.

> The skilled worker visa only requires B1 English

You are technically right, but are ignoring the larger context. Jobs open for Skilled Worker migrants have to be RQF 6+, which usually means the worker has to perform at the level of a university graduate. So, while the language requirement is B1, the skill requirement is non-trivial.

> You have no idea what you're talking about.

Ironic.

My great-grandmother’s home, those of her neighbors, and their church was bulldozed for the US75/I45 rebuild/connection in Dallas in the 1950s. They were given the choice of new public housing built nearby in an industrial area (around Fair Park where State Fair of Texas is held) or figuring it out on their own. Being Black and low-income meant whatever rights they “had” were hard to come by.

I guess my point is rights and freedoms are unequally held, regardless of a nation’s stated values and laws. What makes/made the US great is not that things happening in China couldn’t happen here. It’s that we (used to?) aspire to greater ideals about individual freedom even if it isn’t present for all. CCP and I think Chinese citizens are under no such illusion, and in some cases reject the individual for the collective. (I’m hedging a bit since my understanding is limited second-hand anecdotes from Chinese American friends).

I'm not disputing that, and it's kind of my point. Most home cooks (I would bet millions) are not worrying about "the cutting experience" when they are making dinner. They are using a knife to cut up vegetables or slice meat or whatever. Then they are putting that knife in the dishwasher. Not all of them, but most.

I think my other points matter more. I think people who are invested in the experience as you suggest care about more than just the edge and finish, they care about the weight and balance and feel as well. I think this knife is probably worse on those qualities.

I don't mean to say this knife sucks or that this guy is dumb. It's a cool knife, and he's clearly not dumb. I just think this is more a passion project curiosity kind of thing than a useful product addressing a large market need. Maybe a future mass market version (cheaper steel, stamped, more contoured handle) would change my mind.

What was the SaaS idea was it interesting or do you feel that it was SaaS that was interesting over the idea itself.

Quite often developers don't care about the monetisation method with a product as much as the product itself. It's hard to see why a headshot app/tool or a learning platform is useful to developers.

Maybe something about the B2B SaaS product was difficult to make compared to a headshot or video/learning tool

My first "job" between school and university was to assemble a bunch of keyboards for banking terminals. They used configurable key caps in that a printed sheet was snapped under a transparent keycap cover. I suppose I must have been working on a short production run for a small bank or a trial project, that didn't merit screen printing the keys.

As I worked through countless of those keyboards I mused that what it needed was a little screen on each keycap, so I could just do my job using software.

This was in 1982. Seems like we're nearly there.

I don’t think I’ve had a counterfeit good come in, but the number of times I’ve heard about it led me to start going to other retailers for things I wanted guarantees on: cleaning products, personal hygiene items, and expensive electronics/accessories.

Amusingly after that, I saw I could get nearly everything else off AliExpress for cheaper. My usage of Amazon practically evaporated.

Honestly, it's sad and frustrating. It's literally a "let them eat cake" kind of statement.

China is at the point where a social safety net is needed to ensure long term prosperity, and concentrating on an export first model isn't going to cut it long term, because high value industries are heavily automated and skilled, and simply don't demand or need that many employees.

China has reached a point where the mean years of education amongst working age people (~8 years) has caught up with countries that used to be much richer than China 15 years ago like Brazil, Thailand, Turkiye, and Malaysia and it's mean life expectancy has outpaced all those countries except Turkiye and Thailand, which it is for all intents and purposes tied [0]. This is a MASSIVE win for global poverty eradication.

Yet the median age is significantly higher than all of them except Thailand [1], and median disposable household income remains around $400/mo [2] - lower than Thailand [3], Malaysia [4], or Türkiye's [5] despite having a GDP per capita (~13.3k in 2024) that is comparable to the latter 2 and above Thailand's.

Now is the time for China to expand its welfare system in order to make that leap into being a truly developed country, just like South Korea did in the late 1990s and early 2000s. Expanding the welfare state would help hundreds of millions of Chinese gain the ability to purchase higher value goods thus reducing the specter of "overproduction" leading to the current global trade war, while truly ensuring common prosperity.

Otherwise, it will flounder like Malaysia and Thailand did, both of which used to be South Korea's peer until the Asian Financial Crisis, or Turkiye after it's peak in 2014.

People mention "course correction" but what course correction can you do when disdain for a welfare system is so engrained in the upper echelons of leadership.

This is not a statement on the "collapse of China" (that's dumb), but if this problem around domestic consumption and a lack of a safety net is not nipped in the bud in the next 3-5 years, it will be much harder for China to take full advantage of the capabilities it has and ensure common prosperity.

Yeah, I don’t think the curl example was meant as a knock against curl or advice not to use it. I think any command-line user would agree that curl is not bad or bloated software, which is what they criticize.

The point seemed to be that even a rock-solid tool like curl started out tiny — just a few hundred lines — before growing to cover all the edge cases you’re describing. It’s more about showing that you can start with something simple for your own needs and customize it without depending on someone else.

ChatGPT (I gave no hints in my prompt):

To estimate how many people the *12 pizzas* were for, we can use a standard rule of thumb:

### General pizza math:

* A *large pizza* usually has *8 slices*. * Most people eat *2–3 slices*.

So:

* *12 pizzas × 8 slices = 96 slices total* * If people ate:

* **2 slices each** → feeds **48 people** * **3 slices each** → feeds **32 people**

### Most likely case:

Since this was for a *team* within a 5,000-employee company — probably a local team (not the whole company) — the number of people was likely in the *25–40* range.

### Final Estimate:

*12 pizzas would reasonably feed about 30 to 40 people*, assuming average appetites.

So far it appears the news is reporting a cyber attack in Europe that is affecting European boarding. The RADAR/RADIO (TRACON) thing in Texas and other major airports in the US. A cyber attack on Collins Aerospace and Frontier. And some blame pointing at L3Harris for inadequate failure recovery. Sounds like no one has a clue. I wonder if any of our security apparatus is still functioning enough to provide support to find the source of the problem.

That's neither here nor there.

Amazon regularly commingling legitimate and counterfeit goods, means that customers are left with the job of trying to verify that the goods they ordered are legitimate. For every customer that complaints & refunds, there might be three or more who don't.

Some of these counterfeit products have legitimate safety concerns, for example lead paint usage, battery fire risks, PPE that misstates its effectiveness, or USB chargers with poor AC DC electrical isolation.

This is a huge trust problem, and "the customer needs to detect counterfeits and refund," isn't actually a solution to THAT problem.

Agreed with others it's just what you're used to. I was inverted-y for most of my gaming life because I started with flight sims where it was mandatory, reflecting the real life hardware. So I used the same in FPS games when they came around. Decades later I had kids and had to spend some time sharing a mouse with them, and didn't want to condemn them to a life of having to look for "inverted Y axis" in the settings of every game (+1 to the post above who requested an OS-level setting for this!), so I left it on the default in Minecraft and learned the other way. Now I'm actually bilingual and can swap from one to the other with about 2 minutes warm up time. This is the same as what happens with driving on the left/right side of the road if you spend a lot of time in different countries driving.

With my kids I drew the grumpy line at Minecraft's new Autojump setting tho ... They had to learn with that disabled.

There’s a bunch of books that cover how the food industry exploits your primate brain and tries to make you eat more. Salt Sugar Fat [1] is one.

Not a traditional weight loss guide. But, learning about all the tricks they play made me so angry that I lost eighty pounds… worth a try

When the inside channels set up by the project gaslight people into thinking there is no problem at all I think it is more appropriate to use blogs, where you have complete freedom to say what you want.

Also, blogs have been used since forever to give constructive feedback to other projects, even other programming languages. So I don't understand why it is suddenly not okey for the Zig project.

My doctor in the US just waits for me to get sick enough to push some drug, then berates me to double my dose while shrugging off my complaints of chronic chest pain and dizziness. My friend in med school said she probably gets kick backs from drug companies. My health insurance is like $450/m and covers jack shit.

This article sounds exciting in a world where doctors care and try, though. I’m probably pre-diabetic but I’m not sure how to test my insulin sensitivity as the researchers suggest.

So now you're just changing the subject. Because we were talking about H1B visas and now you're complaining about someone with a different visa type being prohibited from crossing the border. Maybe what's your sensing as aggressiveness is me just pointing out that you don't seem to be talking in good faith or you constantly keep changing what you're talking about without indicating you're actually changing it. Makes it quite confusing to have any kind of cohesive discussion.

I think if you'll refer back to my original response I acknowledge that I do not like The vast majority of immigration related policies that have been instituted under the Trump administration. It was only this one specifically about H1B visas that I do agree with. So you were apparently talking about not H1B visas which resulted in this confusion.

> There's no need to use systemctl edit to make or edit an override file, its just a convenience shortcut

Do you think anyone who's reached this point in the thread has missed out on that? Yes, obviously those steps can be done manually. But that's not what's being recommended here, and it's more steps to learn and remember, and it doesn't really matter whether accomplishing this task requires one extra command or several when it either shouldn't need to be done at all, or should work the same for any config file that needs to be protected, not just systemd service definitions.

It's almost like one of the systemd developers looked at visudo and forgot that sudo should probably never be used as an example of the right way to do things.

This unsubstantiated rumor coming from......the Secretary of Commerce?

"Reuters was not immediately able to establish how the fee would be administered. Lutnick said the visa would cost $100,000 a year for each of the three years of its duration but that the details were "still being considered.""

"Lutnick said on Friday that "all the big companies are on board" with $100,000 a year for H-1B visas. "We've spoken to them," he said."

I admire you. You are a minority, you know that, right?

I don't have time in my schedule at the moment, which says "sharpen the knifes". So for me - it would be amazing if someone solved this problem in a radical way.

Sporadically I would sharpen the knives and since I don't have it in my "skills" section of the brain, I always have to "figure out" sharpening process.

Like some other people said, I drop my phones weekly. Some on wood, some on carpet, and some on concrete. It is so bad that as I have my latest phone for 2 years, I have run across 2 cases, and about to need a 3rd one or go for an upgrade (and buy a new case anyways). I have shattered the glass / screen once but that was a long time back. Yes I am clumsy and I would call myself that even before someone else told me so.

Umm, what? How is a fiber cut an "aging, analog system"? They even admitted that there was supposed to be redundancy in place but the system did not work.

Does Apple even design their own chargers? I know previous chargers have been built by Samsung, Flextronics, and other power electronics companies.

Apple sells Anker chargers from within their online store and possibly retail too so I figured they threw in the towel long ago. Honestly it seems quite overpriced when you can get a similar Anker GaN charger for much less.

And no, this isn't 2004 anymore, non-OEM chargers are outstanding as long as they're not $2 crap off AliExpress.

When Apple stopped including the charger in the box with iPhone as a sleazy money grab, it was a tacit admission that non-OEM chargers reigned supreme. Still didn't stop the pious and devout from shelling out an extra $25 though.

Whether you use Bazel or not, this is a well-known issue with an equally well-known solution. There’s no need for such a lengthy write-up: just use a consistent sysroot across your entire build environment.

If you can’t create your own sysroot image, you can simply download Chromium’s prebuilt one and configure your C++ compile rules correctly. Problem solved.

> Supreme Court has granted 16 out of 19 emergency petitions filed by the executive to overturn those rulings, grants that often require shifts in precedent without written reasoning

The emergency docket does not set precedent. (If you like your Roman law, it is analogous to how a consul acting with senatus contultum ultimum is empowered [1], versus a dictator, who can literally make law.)

SCOTUS has been deferring to the administration around what happens while a case is being litigated. It’s stupid. But it’s not Aileen Cannon corrupt (not yet).

(If I’m guessing correctly, they’re bending the knee with one leg and punting with the other. If the midterms swing even one house of the Congress, the judiciary regains its independence.)

> Phone UI paradigm isn't as easy as "Let's just scale down the Desktop/Tablet applications".

Have you tried modern Gnome/GTK+ 4 applications? You can resize the window to a tiny size and it seamlessly "scales down" to a phone layout. Very handy even on a desktop. Yes, there are real differences besides size (phone UI needs a lot of inactive padding around tap areas because finger taps are imprecise; it greatly prefers swipes to taps, while a pointer-based UI prefers clicks to drag'n'drop; phone UI needs long taps as a secondary action, etc.) but they're minor in the grand scheme of things.

There's another phase we forget about. If I could choose, I'd like to grow up in a giant forest arcology and go hang out with my friends like it's a giant vertical mall with lots of places to go get lost.

When I finally got access to grocery delivery to my door, I could see how it all will work. Carrying things for one person is fine. It's carrying groceries for a household for a week where things break down. Even putting all that on an elevator would be really unwieldy compared to unloading from the garage.

Self-driving and the evolution of early-life education will play a big role in simplifying life without the parents needing to ferry the kids around five days a week.

I know there’s certainly an efficiency tradeoff when AC to DC conversion is involved. For my car the sweet spot for comfort is between 3kW and 6kW as below 3 a substantial percentage (a few hundred watts) is wasted by the inverter and above 6kW the cooling system has to run (a few hundred more watts). For laptops and phones maybe this still holds true at .1C. Some quick napkin math puts that at 5W and at least with PC power supplies they need a bit of load to hit their 80%+ efficiency rating. I imagine it’s a bit different with small bricks?

More to your question the DIY solar community is torn between the benefits of float voltage which is a pretty low charging rate. I bought some cells (not for my house) and on the data sheet they were fine with .1C. They were more concerned with temperature and very high C rates hurting the lifespan. Since I was going to AC couple I was more worried about total system efficiency so similarly staying under a rate that heats the battery up and above the idle power of the inverter was my goal.

Oh, I hadn't heard of that tumblr.

The reality is that without a subscription, the product would not be viable. We would either have to charge nearly double upfront, or risk not being around to support it in a few years.

The subscription lets us keep the starting cost lower, which makes the tech inaccessible for many people. The subscription balances that out, and it also means we can keep supporting the system over time instead of leaving people stranded.

In a sense, it is actually what makes the long-term viability and hopefully trust possible.

That's how we view it.

I don't use knives in my kitchen. My romantic partner does. Yesterday I decided to cut some tomatoes only to find out that all knives are dull.

She never said anything, I didn't know it. Why?

Because she is just "used" to it and to her these knives were just fine. So she never thought about sharpening knives in the first place.

I will take those knives to a pro and he will sharpen them for me, as in a rental I stay in, I don't have the tools to do that and as I said in another comment - I don't have a pain free process to do that as I don't do it often.
