No, I don't think it's suspect, because it seems like you're looking at a narrow-focus of productivity increase.

"advocates are talking about multiples of increased productivity", some are, some are not, and I don't think most people are, but sure, there's a lot of media hype.

There are places that I do think that it can make significant, multiples of difference, but it's in short spurts. Taking over code bases, learning a new language, non-tech co-founders can get started without a tech co-founder.

Django makes querying easier by generating the code for the joins, but you're still joining tables.

The point about SQLAlchemy was specifically about the issue mentioned by the GP, namely having to make more tables for composites. SQLAlchemy does a better job of mapping db tables back to regular objects. With Django you get the `alias_set` stuff but it never lets you forget that this is really a database table. Django uses the active record pattern while SQLAlchemy is a data mapper.

True, but MIFARE Classic is not an RFID system under that definition. It supports cryptographic mutual authentication (although notably the scheme has been pretty much completely destroyed from a security point of view over the years).

The title is quite misleading (at least for people in the field).

“What the fuck is wrong with you?”—what I said—is not nice.

“Maybe just don't even go out in public!” is not nice either. It did not at all have to be that way that my unborn and newly born child and his mother— both high-risk-from-COVID—were in extreme social isolation during the pandemic. We weren’t isolated because we isolated ourselves. We were isolated to our surprise and grief because people simply dropped out of contact due to the hostile socially accepted sentiment captured so well by “Maybe just don't even go out in public!”. Not nice. Not nice at all. There was a gross and ugly and blatant societal failure to protect infants. Infants.

Show HN: We made an app for splitting payments with friends ad-free
Hi HN!

Last year, my friend and I decided to build an app for splitting payments with friends.

We were on a group vacation and trying to split a bunch of bills every day, but Splitwise's clunky UX and ads kept getting in the way. So we decided to build an app for ourselves that's simpler and just does what we need.

We built Quicksplit as a side project - as always, building it took longer than we initially expected :)

It's ad-free and always will be. You can add payments in different currencies, add friends (without them needing the app), and manage tabs for vacations, events, or living expenses.

Quicksplit is a native iOS app (web app coming next!) - it's built with SwiftUI, plus a touch of UIKit for navigation and to fill in some SwiftUI gaps. The backend API is written in TypeScript and running on Deno.

Deno ended up being an interesting choice! It's great when it works (and has improved massively in the past year), but there was still some friction. For example, needing to switch database drivers due to issues with TLS support (which has since been fixed) ¯\_(ツ)_/¯

We're running on Fly.io and Supabase (for Postgres). We considered a bunch of managed and unmanaged hosts (like Render, Railway, Hetzner; serverless databases like Planetscale and Neon). We landed on Fly.io and Supabase because they have generous free plans, are simple to scale up if needed, the latency is good, and it saved us from spending an evening gluing together bash and yaml scripts ;)

Poll: When will we see full Linux distros as official iPhone apps?
I'm a happy daily iSH [1] user, it's an amazing technical project, but I really pine for the day when `apt get blah` will be a reality, using an app available from the official App Store. Be it a paid or free app. CLI only, or with graphics. For concreteness, let's say a Debian-based distro in your iPhone upon tapping Get on Apple's App Store, independently of your location. It is pretty sad that, if this ever comes to be, it will probably be the result of EU/DOJ forces, not of technological advancements.

When do you see this happening (options are number of years)?

But if you respond consistently quickly, then some lazy customers will email you rather than bothering to look in the documentation. So there can be a downside to being too responsive.
I would point out that there is a special syntax / api when you deference “any” in Go. And you are explicitly prompted by the language to consider the case where you receive an unexpected type.

I think this is an important detail, because it’s way safer than in C, where you can just re-interpret memory accidentally and the compiler won’t stop you. Go will panic the thread. Ok, but we already knew that.

The subtle bit is that it’s even a bit safer than most dynamic languages like Python. Because the programmer has to explicitly handle the “unexpected type” case. And because of how verbose Go’s error handling is, every caller up the stack has to consider the error, enforced by the type system. This is different than in Python, where every variable is type any at compiler time, so every line can throw a time error and the callers probably don’t handle it. Even when using “any”, Go’s type system enforces that both the caller and callee consider the “unexpected variable type case”. Overall, it’s still way more of a controlled failure compared to dynamic languages.

It’s great that Go has generics now, to do away with some any hacks. And in general you should avoid any in Go. But when you need it, I think Go actually has a really great reflection API (especially with how it composes with other features like error handling). It’s a bit looked over I think because the difference is subtle at first glance.

It's just astonishing to me how difficult it still seems to be for the Midjourney team to develop a web site that amounts to little more than a textbox, a button, and an img tag.

I tried their new web experience, and... it's just broken. It doesn't work. There's a showcase of other people's work, and that's it. I can't click the text-box, it's greyed out. It says "subscribe to start creating", but there's is no "subscribe" button!

Mindblowing.
I check for an RSS feed, and if it does not exist, subscribe via KTN.

The web browser (or an app with a vague likeness to a browser) would indeed be in the epicenter of a "semantic" leap if that happens.

The technical capability of the browser to be an OS within an OS is more than proven by now, but not sure I am impressed with the utility thus far.

At the same time even basic features in the "right direction", empowering the users information processing ability (bookmarks, rss, etc) have stagnated or regressed.
NATO is learning a lot from the AFU. When Ukraine eventually joins NATO (or even just after the war ends) their veterans will be eagerly sought out so the AF of other states can learn from them!

The OS already does that, though? Your program requests some number of pages of virtual memory, and the OS uses a GC-like mechanism to allocate physical memory to those virtual pages on demand, wiping and reusing it soon after the virtual pages are unmapped.

It's just that programs tend to want to manage objects with sub-page granularity (as well as on separate threads in parallel), and at that level there are infinitely many possible access patterns and reachability criteria that a GC might want to optimize for.

Meh if you’re not picky about the way your desktop looks/acts then you can install it and run __aslongas__ linux has the software you need. If you use office/play games all day long linux probably isn’t for you because it simply doesn’t have the the software you want to run which is the most important thing for people.

> don't pretend we know what the Founders intended with every little nuance of language to justify your own preferred interpretation

I wasn't doing this, so whatever you are arguing against, it isn't me.

> Every other part of law and jurisprudence deals with the words as they are written

So you think that, for example, Wickard v. Filburn, in which the Supreme Court ruled that Congress could regulate a farmer growing wheat for his own use under the Commerce Clause, was just dealing with the words as they are written?

> how can you have commerce without labor

Of course producing things that will be traded in commerce requires labor, but that's irrelevant to the question of whether employment counts as "commerce", which is what I was asking about.
It's worse than that, it's like burying a double or even triple lede:

- it's not just that the hospital told her family totally the wrong thing for a day or a year...

- or even negligently cremated or buried her in a pauper's grave...

- but they also mishandled the corpse, which IIUC is a misdemeanor (corpse desecration, which is a felony, might not apply), by shipping her decomposing body to an off-site warehouse morgue.

- and failing to timely issue a death certificate or do an autopsy prevents determining whether there had been medical malpractice associated with her death.
MIFARE Cards are not RFID cards, and similar systems can absolutely be used as possession factors.

There are also many other authentication-capable cards other than EMV (which is optimized for payments, not really general-purpose authentication) such as various building access cards, national ID cards, ICAO biometric passports etc.

> I implemented double spend protection by introducing a simple operation counter. If the sequence of operation IDs is not continuous, card is blocked. Clones were added to block list within minutes. It was good enough for the use case.

Using that scheme, you could just as well use regular old barcodes, no? Makes for much cheaper readers and even wider compatibility.

> Again, MiFARE is very cheap, so tradeoffs are expected.

There are equally-cheap but secure options that actually prevent cloning or even implement the "electronic purse" use case in a fully offline way.

Usually, MIFARE Classic is only used because there's a huge installed base of readers and/or cards (and/or attached backend software).

> the Randian paradox ... It is ... quite selfless to tell people to be selfish

Unlike most paradoxes, this "Randian paradox" has an easy resolution: it's utter bullshit parroted by asshole psychopaths who have been wishing desperately their whole lives for justification that their utter disregard for the wellbeing of their fellow humans is actually a good thing. It's not.

> the first principle of being a wolf among sheep

and one way to spot an asshole psychopath is that they divide the world into "wolves" and "sheep" and, of course, put themselves in the "wolves" category.
That assumes that employment counts as "commerce", which, as another subthread elsewhere in this discussion will show you, is not an assumption that I think you can just help yourself to.

a variable capacitor will present some mechanical resistance and thus conversion of mechanical energy into heat, at low speed this is negligible (unless you need the system to behave reversibly), but if you are going to rotate your variable capacitor at speeds where frictional heating becomes an issue (perhaps the generation of heat limits your application, or the loss of mechanical energy limits your application) then yes these types of dielectrics will be of interest to you.

Otherwise, conventional dielectric can be more compact for the same maximum energy storage in the capacitor, since no simultaneous optimization on viscosity was performed in their selection, resulting in a wider range of dielectrics being viable.

How fast do you plan to turn your variable capacitors?

I get the impression that career Windows C++ programmers, and especially game programmers, tend to really like Visual Studio. Especially IntelliSense and the debugger.

Yeah, the example is not representative - in reality there's a couple of smaller vectors (base prices, meal prices, supplements, discounts, taxes, cancellation policies, ...) + lots of vectors containing indices (`for 2018-01-01, match prices #10, #20, #21`, `for 2018-01-02, match prices #11, #30`, ...), and they can't be actually updated in-place, because that would require using `RwLock`, preventing the engine from answering queries during refreshing.

(which is actually how it used to work a couple of years ago - ditching `RwLock` for `ArcSwap` and making the entire engine atomic was one of the coolest changes I've implemented here, probably worth its own post)
winget seems like a minimum effort to say they have something that seems like a package manager, from what I can tell it's a big index that either hooks into the msstore, or points to a regular installer with a version number that usually runs in silent mode.

Packaging like linux has had for decades would seem like a huge uplift for windows if they could do it, especially if it could be done with modern approaches to isolation.
