The other weird unit for measuring air conditioning is "tons". One ton of air conditioning has nothing to do with the weight of the air conditioner. Instead, it means the air conditioner provides cooling equivalent to one ton of ice per day. One ton is almost exactly 12,000 BTU/h; curiously, the round number is a coincidence.

But isn't this constant idea that Apple and other OS providers should add more features to their platforms ultimately counterproductive?

If, as a developer, I knew I only had a couple of years at best before Apple replicates my app, would there be any incentive for me to create the app and pay Apple the $99 yearly fee?

The Apple App Store is a lot like a shopping mall with Apple as the landlord. Imagine you rented a spot from Apple in the mall to sell your products. Then, Apple, afraid of being left behind, starts creating the same exact shop next to you, selling the exact same products cheaper since it owns the mall. This would cause you to lose customers and eventually close down.

If this trend continues, there could come a point where every app is replicated by Apple.

These app owners would go out of business, and the App Store would become nothing but a catalog of Apple apps and other apps created by Microsoft, Facebook, and the like.

Is that good for the indie developers at the end ?

I can foresee a world where the indie software developer doesn't exist because the platform owners are essentially offering their products for free.

How about the customer ?

As Apple isn't obligated to provide anything good in terms of software, just a free alternative that's baked into the OS, would that even matter in the end?
> If you don't need stealth, you can send an F16 instead.

Not necessarily? An up-to-date F-16 block is still pretty expensive to field and needs external pods to do a lot of the stuff the F-35 can do internally (laser designation, IRST, advanced datalink, the works). It has a far smaller combat radius (295 nmi versus 669 nmi) and isn't outfitted with modern A/G weaponry outside SEAD missiles like the HARM.

There are a whole number of reasons why you'd want to field an F-35 in the F-16's place, even without stealth on the table. Low radar response is the cherry on top of the strike package.
Ride sharing app using Flutterflow or Bubble?
I'm planning to build a ride sharing app using a low/no code platform. Hoping to use Claude for customizations, if it is an option. Looking for advice from folks who have used FF or Bubble (or both).
Looks like an open source competitor to this absolutely magical app I used to use back in my Windows media PC days, way back when, which was called VideoReDo.

(Unfortunately, VideoReDo was proprietary, produced by an indie developer, and that indie developer recently passed away.)

For those who don't really get what "lossless" video editing is all about, consider that most video editing software always involves these stages: importing video/audio "clips", storing the video/audio timelines in some sort of "app native" format (e.g. Pitivi, Premiere, Final Cut), and then exporting the completed video in one or more output formats (e.g. MP4, MOV), re-encoding the entire thing from scratch.

This means that if your only goal is to, say, cut 30-90 seconds out of a 1-hour video, you're still going to have to re-encode the entire 1-hour video. That also means if your re-encoding system isn't a match for however the original video was encoded, you'll make some changes you didn't intend via the re-encoding (e.g. video or audio quality changes).

With this "lossless" style of editor, however, it'll figure out a way to "snip out" the 30-90 seconds (you can think about this being "at the byte level") without re-encoding the entire thing.
This was the most interesting point for me, and I assume most of my IOT type shit has this functionality.

Worth remembering that airlines don’t handle your luggage themselves and instead contract it out to ground handling companies.

It would be more interesting to map flight carriers/numbers to handlers (e.g. Menzies) and regions to give a more reasonable blame/availability overview.
"So be more optimistic than your comments lead you to be."

I think I am as optimistic as one can be, without closing my eyes to the reality on the ground. Where I live, the AfD got 40% of the votes. And further east, poland and co. are not that keen on phasing out coal, either.

Thinking coal is definitely going away, because some letters on a paper currently says it will happen, is dangerous I think. It will go away if there is continiously active support for that transition. So far china is also still building lots of coal plants, despite their solar panel production.

Just to clarify:

If you hold the copyright over the code, you can change the license to whatever you want, whenever you want.

In other words, if you are the lone dev of a library that has been GPL for 20 years, and then you get hired, and you want to use that library at your job, you can just make a copy of it and say "this copy is yours to do with as you please, have fun". You don't even need to mess around with dual-licensing. Licenses affect only people who aren't the copyright holder.

There may be different definitions, but also a lot of incorrect information. Nothing changes with C23 except that we added a note that clarifies that UB can not time-travel. The semantic model in C only requires that observable effects are preserved. Everything else can be changed by the optimizer as long as it does not change those observable effects (known as the "as if" principle). This is generally the basis of most optimizations. Thus, I call time-travel only when it would affect previous observable effects, and this what is allowed for UB in C++ but not in C. Earlier non-observable effects can be changed in any case and is nothing speicifc to UB. So if you call time-travel also certain optimization that do not affect earlier observable behavior, then this was and is still allowed. But the often repeated statement that a compiler can assume that "A is never true" does not follow (or only in very limited sense) from the definition of UB in ISO C (and never did), so one has to be more careful here. In particular it is not possible to remove I/O before UB. The following code has to print 0 when called with zero and a compiler which would remove the I/O would not be conforming.

int foo(int x)

{

printf("%d\n", x);

fflush(stdout);

return 1 / x;

}

In the following example

int foo(int x)

{

if (x) bar(x);

return 1 / x;

}

the compiler could indeed remove the "if" but not because it were allowed to assume that x can never be zero, but because 1 / 0 can have arbitrary behavior, so could also call "bar()" and then it is called for zero and non-zero x and the if condition could be removed (not that compilers would do this)
I'm thinking you could also create gravity waves by annihilating matter and then creating matter over and over. If you could get a bit of that wave to reflect back to you and then sync your creation/annihilation, you could build a huge wave over time
The article mentions the un-bundling of fees and charges for checked bags,
but doesn't give it enough weight.
As a counterpoint, the author writes, "Southwest Airlines passengers, who can check two bags for free, still seem to fight over limited space in bins."
Assuming that is true,
we're now in an era where passengers are conditioned to carry-on bags.
Changing their behavior solely for Southwest is unlikely, and
also Southwest is a regional carrier,
whose clientele are going to packing for shorter trips,
and thus have less to luggage.

Commercial passenger air transport today is dystopian,
and the small comfort of having your luggage with you to avoid fees, checking bags, and baggage claim,
just to get in and out of the airport as quickly as possible is perfectly rational behavior.

One quick suggestion on project structure:

Move all the structs from models/ into the root directory.

This allow users of this package to have nice and short names like: q.Message and q.Queue, and avoids import naming conflicts if the user has its own „models“ package.
"Overall, this migration proved to be a massive success" but their metrics shows this migration resulted in, on average, slower response times. Wouldn't this suggest the migration was not successful.

"At the time, it was widely believed that when a runner slowed down, a few vigorous taps on the head with a wooden mallet would revive his spirits and encourage him to renew his efforts. J.

It’s also fair to point out that someone who doesn’t litigate administrative law cases probably isn’t qualified to offer an opinion on an interpretive practice in administrative law.

But I’m curious to understand where this newfound sanctification of precedent comes from. Stare decisis has always been discretionary. The Supreme Court overturned 34 precedents in the 1970s: https://constitution.congress.gov/resources/decisions-overru.... Many of those were 50+ years old. It overturned about two dozen in the 1980s and 1990:. The current Supreme Court has overturned just 10 in 6 years and is on pace to overturn 15-16 over ten years, about the same number as from 2000-2010.

In reality, we are in a period of historically high respect for precedent. So ask yourself why this is suddenly being painted as a period of judicial activism.

Indeed, and if that software can't point to some contract or license that suggests someone else is liable, then they are responsible.

Funnily enough, almost all open source projects not only disclaim such liability in very large print at the top of their licenses, but they don't even complicate the relationship with some kind of purchase agreement and renumeration.

They literally just say "Here's a thing. Use it if you want, change it if you want, but you're responsible for making sure it meets your requirements."
> When you provide software that is widely used and that people rely on, you automatically created a community where fixing bugs is an obligation. Your software has become a corner stone in other people’s software stack/life and so those people and their issues with your software have become your problem, too. If you want it or not.

Maybe you believe they have a moral obligation, but under the most popular open source licenses, they have no legal obligation to fix bugs or be held responsible for the damages caused by their bugs, regardless of whether people rely on their software for critical software.

I don't drink a lot of the stuff, but I haven't quit.

I used to drink about a litre of brewed coffee a day, starting at 7AM and going on until 5PM. Eventually that fell away, without any decision on my part, and I now drink one mug a day (1/2 imperial pint), after getting up.

It doesn't seem to power me up or make me more alert; I think it actually makes me dozy, 2-3 hours after my morning joe. That is, I think I only notice the crash.

Honestly this kinda shows me that no matter what degree of robustness we design into our systems (null saftety, memory safety, thread safety etc.), some types of system breaking bugs are unavoidable (such as DOSing the system by calling a system API function in an infinite loop), and are often impossible to distingushing from desired behavior.

There are, for instance GNU Taler: <https://taler.net/>. But what you want is an implemented system of digital anonymous cash.

Not mentioned in this article, but certainly related, was the Canadian governments unprecedented step to freeze hundreds of bank accounts of protestors during COVID protests using their Emergencies Act.

I also don't think the comparison makes sense for a number of other reasons:

Microsoft had a real market share monopoly. Apple has a vertically integrated platform that tends to include the most monetarily valuable users.

Microsoft was regulated using long standing antitrust law and a court settlement outlining specific compliance steps. Apple is being regulated by a brand new, extraordinarily massive law that is untested with tons of unclear requirements.

Certainly, innovation might survive in the EU. But nothing about this post or comparison seems well reasoned.

Money-less society with security to stop hoarders looting stores.

All digital security ends up security through obscurity; encrypt with noise the data along some algorithmic path to obscure what the data is, divide up go has admin and tier their access to obscure who is needed for what.

There still needs to be someone with full control over the AWS account or whatever to grant further permission. There’s no perfect system security and anonymity if someone out there can drill in and use admin/keys to unwrap things.

That’s why governments like CEOs and root nodes on such groups; keeps surface area for getting what they want small.
Users flagged it. We can only guess why users flag things, but here's what I can tell you: (1) it was an unusually large number of flags; (2) the average account age of the flaggers is more than 8 years, and most are active contributors on a wide range of topics; and (3) I looked through all their flagging histories and found only one whose flags were consistently political and one-sided. That is not the case with any of the others, and nearly all seem to be using flagging as intended.

In the past it has been helpful to mention a list of "users who flagged X also flagged the following", so in that spirit, I've included a list below. The point here is not that all those other flags were good (a few were in fact bad), it's that the accounts are flagging a wide variety of stories and not in a predictable way.

Thank you for the kind words! I wanted to get something out even if it doesn't have the scalability stuff built. But I have been thinking and architecting that behind the scenes, and now I "only" need to turn it into code.

I think the queue itself will end up using a number of technologies: SQLite for some data (ie, organizing messages by date and queue), RocksDB for other things (fast lookup for messages), DuckDB (for message statistics and metadata), and other data structures.

I find that some of the most performant software often uses a mix of different data structures and algorithms by introspecting the nature of the data it has. And if I can make one node really sing, then I can have confidence that distributing that will yield results.

I think SQLite is a great start, but I really do want the software to be able to utilize the full resources the underlying hardware.
Good developer experience doesn't make developers interchangeable. It reduces the roadblocks (cognitive, technical, and aesthetic) that makes a developer's job harder, which means those same developers can get their job done more quickly.

In product-speak, it makes it more likely your product is adopted broadly.
