The distinction between extractive vs value-creating profits is very important.

That said, it's not automatically a "sweet deal", and identifying that difference is nontrivial. The same activity could be one or the other, depending on how it is done. Your example with a landlord is particularly thorny:

>>But how much does a landlord actually produce things of value, ...?

A good landlord creates a building from nothing, and maintains it in good condition for his/her tenants. What was an undeveloped parcel of land is now homes for all the families who live there. Considering all of the people yelling about lack of housing, that is something of real value. Even maintaining a building in good condition is a very expensive activity, and if the maintenance is not done, the homes will certainly revert to rubble.

So that good landlord is absolutely creating, for both his renters and society at large, serious value.

OTOH, a bad landlord doing superficially the exact same activity can be completely extractive - merely collecting rents and failing to maintain the building(s) in any way beyond what will keep them out of immediate trouble. The bad landlord extracts everything they can for current cashflow and allows the building(s) to degrade towards rubble, an anti-creative activity.

One is definitely creating value that is highly needed in our society, and the other is destroying and extracting it, yet both have the same business type, both have the same income and cost structure, etc..

Even more difficult, the same landlord can look like one or the other in different times - in high-demand times and/or markets, they can charge premium rents and profit while still doing lots of maintenance & upgrades, but in a down market, they may have high vacancy, and still lose money while doing the absolute minimum.

So, how do we tell the difference and tax them differently?

That's a serious question, and one which, if we can find an answer will really help the society improve.

Understanding JSON Web Encryption (JWE)
The problem is that these things are deeply personal. And this one is really, really close to what I'd want myself. Yet... I still wouldn't buy it. Here's what I'm using right now (actually I have the wireless version which they recently stopped producing): https://www.lenovo.com/us/en/p/accessories-and-software/keyb...

But I couldn't deal without the trackpoint, which I use regularly for simple mouse actions even when I have a mouse just inches away. Also my right pinky actuates the emacs "meta" key using the key immediately below "/" (it's the RCtrl on the Lenovo), and on the Altar I that key is offset from the row above, which would be a muscle memory collision[1]. And there are no volume control keys mapped, which I find I use very regularly in the post-pandemic world of constant online meetings. (But it does have display backlight buttons? Why?! You don't use external keyboards with laptops. Seems like a weird choice.)

(Also, a nitpick: the backspace key on the US layout is marked "del" on the keycap. I REALLY hope this is a typo and that the key doesn't send Delete instead of BS when pressed!)

Beyond that though, this really does look great, and if I wasn't wedded to the thinkpad keyboard I'd definitely consider it. But... I'm a really small market, and even I'm not quite onboard.

[1] And this is the primary reason why I've stuck with Thinkpads for more than a decade. This isn't a standard key position, but Thinkpads (not even Lenovo generically, most of their other keyboards mess this up) do it best for what I want.
I still have my sew awl I bought for fixing gear out field. It's a very useful skill.

You can also dampen the resonance, to limit its response at the resonance frequency.
Private companies likely would have clusters that dwarf the majority of computers on the public lists. Except they don't tell you about them.

Why would they? So their competitors can copy their business plan?

IBM has had large clusters for decades.

Any large bank or trading company would have clusters that would be at home in that list.

You don't want to know what the Apple cluster is like: they have to train for Siri, in multiple languages, etc. I be that's several orders of magnitude larger than Tesla.

AWS itself is probably several orders larger than most university clusters, probably larger than most country's combined computational capacity.
Because the effort to maintain a growing list of bookmarks organized is too high for most people. So most people don't use bookmarks, so browsers are trending towards putting less effort into a feature people don't use.

I love the website and am attracted to the keyboard. It looks really beautiful and carefully crafted. I'd love to try it.
As has been said before: Users are almost always right when they say a problem exists; but they are almost always wrong when they suggest a solution.
This is among the worst takes I’ve ever seen, to the point that I might adopt this as an interview question to avoid ever +1ing a hire who thinks in this way.

If you need broken old stuff to run, the onus must be on you to disable the security, not the other way around.

How about the Delphi community edition? https://www.embarcadero.com/products/delphi/starter

It would be nice if there was a standard for snap-on numpads, or even the cursor-plus-six-key-block-column, to be connected to either side of a keyboard.
I miss Delphi.... even though I've got it installed.

I can't bring myself to use it.

The "free" version has a hook in it that just doesn't sit well with me... they want a cut of any money I make with it, on their terms. It's easier for me to ignore it, and just put up with the limited documentation of Lazarus. I miss the days when I could afford Delphi.
$14.5 Trillion dollars sure seems like a lot of money.
Hmm, sure. Perhaps Austria and Germany are a bit culturally traumatized by the horrors they inflicted upon the world under an ideology, and they wish (based on historical data) to prevent such an occurrence again?

I don’t feel qualified to say whether this is effective, but it’s pretty obvious why this is characteristically different from “ruling class wants to crush all dissent against ruling class.”
From what I know professionally, issues during the pandemic existed beforehand. Like a lot of things, the pandemic just exposed or exacerbated them.

On the other hand, with the pandemic in particular, I think a lot of what's been attributed to the CDC is really better focused on the FDA or higher-level administrations. Not all of it, but more than seems to be acknowledged. News announcements about revamping the CDC seem to take attention away from other places the scrutiny should be directed at.
I think it already is happening in the US, even in cities that are currently considered "nice". There is no overarching ethos that the citizens hold regarding small economies and city design, and so anywhere with a lot of Americans is subject to the centralization of commerce and the development of cookie-cutter, investment-group-owned cheap buildings.
Does anyone here have a framework for iterating with end-users to determine what their needs really are? Maybe some question phrasing that can be used to extract the core of the user's needs?
Thank you for the kind words.

For now it is just linear switches but it may be possible to offer a choice of switches down the line. I'll look into it.

I don't know why you keep being so aggressive but you don't know me or anything about me and you're making weird wide ranging judgements just based on the fact that I'm asking for advice on how to find more interesting jobs.

Not everyone has to be an "entrepreneur". I like making things, not running companies and managing people/talking to investors and all the other things that come with trying to create a startup.

And yes, sorry but if you're not aware, some people have life situations that don't allow them to simply quit their job and start a company without a safety net. There's a reason the vast majority of "entrepreneurs" are of a very specific demographic
Assuming it's true, it makes you wonder what other ideas are appropriations. Buckminster-Fullerene / Bucky-balls?
One of the most interesting ideas I saw during the COVID-19 crisis about the balance of pharam research and distribution of new vaccines: What if the gov't guaranteed a price-per-vaccine and number of vaccines to be purchased if a new vaccine could be created? This is basically the scheme of Operation Warp Speed. The US gov't dumped tons of money into a few great ideas, then guaranteed to buy if they were approved by FDA. It stimulated massive parallel investment and created a few new vaccines in the shortest time in human history.
Job boards can be pretty terrible. I try to find companies doing something interesting and apply directly through their site. You can also find yourself among less competition if their jobs aren't being picked up by big boards.
It might be possible to train a neural network on the RF emissions vs the image displayed and make it able to reconstruct the image based on the RF emissions. Might be blurry and noisy but worth a try!
I dont think it was dogmatism. I think they genuinely didnt think we had time to write tests, etc. and when I argued that we should do it to be more "agile" because we'd all committed to being agile up front (in theory) they googled what the principles and said "look, thats not what agile says".

I agree that arguing from scripture is awful. I havent tried to do it since. I would like to see some other sort of anti-waterfall set of principles that I could get behind though.

I used Delphi years and years ago and it was great for building GUI applications quickly and easily. Much nicer than Visual Basic. I probably wouldn't recognize it now, other than I suppose it's still Object Pascal, which is a very good programming language, all things considered; straightforward, not too fancy, not too dumbed down.

Sunflower oil is mostly linoleic acid; its profile is unhealthy according to current thinking (and my shaky understanding). You’re right about olive oil, which is supposedly good for your heart.

EDIT: unless by “high-oleic sunflower oil” you’re referring to some special variety?
I'd love to go back to Delphi and play with it again as I did back in the day, but the price tag kills the mood pretty quickly.
It depends on what you consider interesting. I look for:

+work in person

+biz is generating revenue

+there is a physical system that the software interacts with that I have some degree of physical access to

+Follow other interesting and likeminded colleagues you've met to places that they go.

Other things:

+Look for places that greybeards tend to stay around.

+not in the trendy part of your city. It's gonna be in an older, more run down area. Or outside of the city in a burb or more rural area.

+Usually, the tech isn't going to be sexy. You probably won't be working with cloud tech, at least not exclusively.

What is the mechanism here?
The majority doesn't smoke (anymore - this would have been false 40 years ago and so different results), and so won't care.

Most people have gas cans, but didn't know that they cared about the spouts until a change was made that caused them not to work. People have better things to do than keep track of all the details that congress is doing, and I'm not sure anyone anticipated that the change would result in making gas cans unfit for the purpose of getting gas from a pump the your lawn mower. I can't blame people for being mad about it though, new gas cans either don't work or are very expensive for what is in the end just a container.
It’s very impressive, but you’re in a crowded market. If I have one piece of advice, it’s go international if you’re having sale problems. No one is really selling anything but US keyboards. I had to resort to custom designed keys to get a Canadian Multilingual.
You can build a house without a heating system. What you do is build it to better than PassivHaus insulation standards and then use the active ventilation system to cool down the house in summer when the sun is shining and the solar panels are working.

It's always struck me as odd that we continue to try to heat up houses in winter when solar panels work better in summer.

Highly insulated and airtight houses always seem to me to be candidates for cooling down rather than heating up.

Build with excess heat in the building, move that to the hot water cylinder, or vent outside as required.
Only the best memories for Delphi.
Ask HN: Online maths courses that teach the why?
Long story short - Are there any maths courses that teach why things work, instead of ways to move numbers around in notation?

Hello, I'm 16, in the UK. I've always struggled with maths in school despite enjoying it in other areas (when programming, and in videos by ThreeBlueOneBrown etc). Exams tend to be alright because I can problem solve, but I've never found it easy.

My 10 year old sister's been having a similar experience learning fractions. I sat down to help her with some homework and quickly discovered that instead of teaching her what a fraction is, she's learnt a series of heuristics that get the right answer for a given question while not understanding what she's actually doing. I started to teach her what fractions actually are - to the level of "Fractions are parts of something", "1/2 means one half of a whole", "the bottom number means how many parts the whole has been broken into, the top number how many of those parts you have" - etc. It finally clicked for her, so we decided to go over her assumptions regarding decimals as well: Again, they'd taught her "zero dot twenty-five means one over four", instead of what they actually were. 20 minutes of explaining place value later, she's gotten that too. By teaching her what things actually are, I've gotten her past months of falling behind a class as she struggled to learn the heuristics. I'm not a particularly good teacher - it's just the way it's been explained to her that caused issues.

That experience prompted me to think about my maths education, and I've had the same issues - e.g. I've learnt several rules for computing trigonometry, but I have no idea what sin, cos, and tan really are. This post is getting long so I won't go into more details, but I think I would benefit from resources that teach mathematics that way - teaching what things are, not just how to manipulate them through tricks. I'm starting maths and further maths A levels in a few weeks. I've looked at resources like ThreeBlueOneBrown, and while the quality of the content is incredible, he doesn't cover anywhere near the breadth of content I'll be doing[1]. I would really appreciate recommendations for more content like it, that explains secondary (high) school mathematics using the why.

I'd suggest not doing this.

What you're doing is not novel. You have a much better chance if you focus e.g. food and beverage.

There's many reasons but your setup will go smoother, GTM will be easier and you will get higher NPS. You will also have the opportunity to develop novel aspects.
Calling RAD Studio a high-quality IDE seems like a stretch to me. I would choose VS Code or a JetBrains product any day of the week. Unfortunately you a kinda stuck with it when developing in Delphi.
For me when Borland became Embarcadero, it seemed like it lost it’s scrappy hacker ethos.

Turbo Pascal, Turbo C, Delphi, C++ Builder were all very innovative products that catered to the individual developer. The Embarcadero rebrand seems like a turn towards Enterprise.

For me now, JetBrains is the new Borland, a scrappy company with a strong focus on what individual developers need and consistently turning out excellent software.
>see some research...spaced repetition into our actual education system.<
I have followed the research in this area closely for several years. Most of the (excellent) foundational research was done by university psychology professors who used college students as subjects; it's much harder for them to use primary school students, hence far less research with young learners. Implementing these techniques in elementary schools is more challenging then many would guess. Two good books: "Make it Stick" Brown, Roediger, McDaniel; "Powerful Teaching" Agarwal & Bain. PM me if you'd like more info. The second book describes research with middle school students. Pooja Agarwal also hosts the informative site www.retrievalpractice.org which informs K-12 teachers and has lots of free downloads. I am involved in a startup that is beginning (pilot teachers in September) to implement spaced repetition for elementary school math.
I use a custom built corne keyboard which staggers the columns based on finger length, but not the rows. I don’t think I will ever go back to a standard layout keyboard after having used this for a few months.

I still have the feeling it's the most productive way to create beautiful native Windows desktop programs.

Rapid application development is not an empty promise here.

All my other endeavours with UI programming (Java/Swing, HTML/JS frontends, QT) felt way less productive. Maybe MS C# is the closest to Delphi nowadays.
This is really impressive, well done. I love the design, how premium it looks, and the site itself.

Really amazing work, I'm blown away. Well done.

For practicality reasons, I guess best would be a mixed system: have 80% of your rooms reservation based, 20% on a reserve "first come, first serve" approach, which I can get by randomly showing up and paying a premium fee.

Amazing job! The keyboard looks great. I have a couple of question for you regarding how you built the prototype and how you are planning to manufacture it. I am building something much less ambitious but also a hardware project and could really use some answers to these questions.

* How did you get the CE compliance? Did you literally just fork out a couple of grand and send the prototype to a lab to do it for you?

* How does creating the prototype vs. getting manufacturing going look like? Did you create the aluminium body yourself in your garage, then started getting in touch with Chinese companies to see who could manufacture it? How did you find the contacts for these?

If anyone else has tips for these kinds of things, I'd appreciate them also. The CE compliance in particular is quite daunting.
