If they can sell them for more than they purchased, why even drive them for a bit?

I think rental cars have a lower value/prestige compared to single-owner used cars (the idea being people are rougher and more careless with a rental they only use for a few days).
> I think you’re assuming people are incapable of determining scope on their own, just like you’re assuming that programmatic testing is a magic bullet for finding software regressions / bugs.

You are arguing against a straw man, as I don't assume either of those things. Testing a magic bullet? Ludicrous.

> You are aware that there is such a thing as a Pontiac and such a thing as a Mercedes, right?

Hmm, but both a Pontiac and a Mercedes present the same driving interface.

Wouldn't it be possible to broadcast local magnetic declination over ATIS or other automated broadcast systems?

As far as I know (and according to the article), modern navigation systems contain databases of the local magnetic declination anyway; instead of updating maps and navigational databases, we could just update these declination database instead every once in a while if I understand it correctly.

Yes, and that's fine, provided they quote them accurately and not deliberately misquote them.
I've done something pretty ridiculous to solve this problem and I'm not sure I'd recommend it, but here it is:

- A directory is synced with the server with no conflict resolution
- The application creates its config file in that directory, named by a random UUID, which is stored outside the synced folder
- The config file stores the setting overrides (defaults were compiled-in) in any format (I used YAML)
- Each setting override includes a "locked" and "lastModifed"
- On startup (sync was external) all files in the directory are read and merged starting with the local one, then skipping any settings that are locked (locally or remotely), last modified wins

Some deployments used a daily rsync cronjob, some had a mounted network share (with hilarious broken file locking) and of course it worked with direct bind mounts as well.

I also briefly experimented turning the "locked" field into a "group" field to enable multiple "sync groups" with some keys shared globally and some only with other group members (even different groups for different settings), but it ended up not being useful for my use case, although it did work.
And because of that Pidgin is horribly unreliable. Don’t get me wrong, I used it for years, but over time all the plug-ins broke for one reason or another.

It is a western liberal idea because it is clearly laid out in the founding philosophical texts which were written in the west (thus western) and which provide the theoretical definition for the term 'liberal society'.

Examples include Hobbes, Locke ( all persons are endowed with natural rights to life, liberty, and property), the US' founding fathers writings and debates, the French national motto of Liberté, égalité, fraternité, ...

You are correct that many/all western liberal governments are adopting very harsh laws contrary to these principles.

This does indeed call into question if these are still liberal democracies/republics.

It is the sad state of man that very few social structures are able to adhere to the principles on which they are founded.

Well in this case we have a potential screwup, which doesn't seem to have had any consequences or to be directly related to the current crisis. On the other we have people wilfully lying, knowing that their lies will kill people, for their own political benefit.
Thanks for the clarification, I only remembered the "locked" behavior, and that seems to be what is discussed in the article (see main screenshot). I agree that closing without locking is a good enough middleground (i.e same as tagging the issue).
Then how is it evolution? I thought evolution was where the DNA changed to create a new species, and took millions of years.

I agree, this is incredibly frustrating. Sometimes it's hard enough to even get developers to reopen issues closed for inactivity, if they're locked it's even worse. I often don't even bother trying to open a new issue for the same thing unless it's critical, I just leave in frustration.
The basic idea I have is that when you bring to market a new technological product, you need to register it with your government/jurisdiction and depending on a few params (maybe company size, revenue, funding, industry/vertical etc.) provide more information.

Similar to tax and accounting regulations, as you grow these regulations grow, too. For example you might need to provide risks and threats analyses for your technology.

You're liable to provide this information to the best of your ability given context (e.g., they wouldn't require a 30 page risk analysis from a indie hacker who has 20 users). If it turns out that you provided false information delibrately, or acted in bad faith, there are consequences like fines, bans, and so on.

Of course, based on your technology the government can prohbit you from bringing it to market, add constraints or require more info.

Freaking downvotes. What ever happened to actually discussing the technicals here on Hacker News?

I'll help ya out. Kogge-Stone is the paper from March 1972 that states that ANY recurrence relation "x_i = f(b_i, g(a_i, x_i-1))" can be parallelized, as long as f and g satisfy distributive and associative-like properties, "executing in time proportional to log2(n)" (aka: O(log2(n)), but this paper was probably before O-notation was popular).

The if the Kogge-Stone algorithm is executed sequentially, time is proportional to n.

https://ntrl.ntis.gov/NTRL/dashboard/searchResults/titleDeta...

As you can see, Kogge-Stone can efficiently parallelize (aka: execute O(log2(N)) depth, O(N) total-work) a wide variety of recurrence relationships that initially seem sequential.

-----------

GPU programmers know this pattern as prefix-sum. In CPU-architecture books, its called Kogge-Stone.

----------

Maybe this will help? Lets say "1" is "this byte is a start-of-instruction" and "0" is "this is not the start-of-instruction".

For example: "1 0 0 1 0 1 1 0" would contain instructions at i_0, i_3, i_5, and i_6.

Now prefix_sum(1 0 0 1 0 1 1 0) == (1, 1, 1, 2, 2, 3, 4, 4)

f = 1 0 0 1 0 1 1 0
g = 1 1 1 2 2 3 4 4
idx = 0 1 2 3 4 5 6 7

So lets say we have 4-parallel decoders. Decoder #1 gets index 0, 1, 2. Decoder#2 gets byte 3 and 4. Decoder#3 gets byte 5, decoder #4 gets byte 6 and 7.

See how that works? Just Kogge-Stone it up.

----------'

I assert that "f" itself can also be computed using Kogge Stone, but maybe splitting it up like this is easier? Or will I also have to prove "f" for yall to see it?
In my opinion, domain experts have a moral obligation to speak up regarding policy that involves their area of expertise.

On the topic of encryption, we're the only community with an understanding of what "breaking encryption" means. There are no skeleton keys, only vulnerabilities. We have a moral and ethical duty to fight for encryption, privacy, and security, not against it.

What exactly does this have to do with the topic? Your first paragraphs are talking about treatment of whistleblowers and Hillary Clinton is (obviously) not a whistleblower.

Adding in a Clinton dig just adds political derailment to the topic for no particular reason.
> For example, plenty of people I know including myself would be strongly against less encryption, but strongly for more government control of tech companies (not via less encryption but via other means).

But that’s not what Haughen is lobbying for. She’s explicitly saying that end-to-end encryption is bad because it doesn’t allow Facebook to monitor private communications enough.

I’d be surprised if you could find more than a tiny minority in the tech communicate who agree with this.

It looks promising. Which frameworks does it support?
Snowden is assuming that Worldcoin is saving hashes of eyeballs. That is not what Worldcoin is doing. Zero Knowledge proofs allow the system to prove that an eyeball exists without actually tying the biometric hash directly to an ID.

From the article:
"We use the open-source Semaphore[19] zero-knowledge proof system to transfer the uniqueness of IrisHashes to the uniqueness of user accounts, without linking them."

Now, of course, one needs to trust that Worldcoin is actually doing what they say they are doing, but that is a different discussion.

Edit: I see now that they are saving this data during field testing. But it looks to me that the long term plan is to use ZK crypto to unlink the hash from the account. Snowden's "hot take" ignores this.

How Russia Is Cashing in on Climate Change
This sort of bug only happens when running a multithreaded program (with shared memory) on a multicore processor.

You do need both for the problem to happen: Without shared memory, there’s nothing to exploit. And with a single core only, you get time-sliced multithreading, which orders all operations.

My point is, that combination was a lot rarer in ARM land before people started doing serious server or desktop computing with those chips.
> Less monitoring on private messages

As pointed out on The Last Week Tonight show, private messaging apps are a cess pool of misinformation [0] especially in the developing world.

But: Facebook can and does monitor private messages whenever any user flags / reports them [1]. The problem is, how effective is the mechanism given not many know it is even there. Of course, e2ee mustn't be compromised but it should also not be used as an excuse to let misinformation run amock. May be homomorphic encryption gets us there, may be UI changes do. I hope Facebook does act swiftly and decisively whatever the case, since e2ee (backdoored or not [2][3]) seems like the scape goat here.

I already have a way to unify my messaging across different apps. It's called MacOS and cmd+tab. Sometimes on the road I use something called iOS. Sure it's not the same. But is it that different either?

All messaging apps have their own native features, some have E2E encryption etc. Not sure if there's a common subset that is enjoyable enough to use that it's worth it.

That being said, I do wonder what will be the "Facebook Events" (invite all your friends to an event) equivalent in the future when everyone is in a closed garden chat platform instead of Facebook.

In response to: how did Apple do this?

Mobile app advertising on iOS has long relied on Apple's IDFA - Identifier for Advertisers - a random, device-unique, resettable identifier that was available to all apps.

An app like Candy Crush would tell ad networks like FB that "IDFA 123456 just installed the app" or "IDFA 654321 just made a $5 in-app purchase." FB could then recognize that IDFA as a user who installed the FB app, and they could use that data to target, optimize via ML, and measure the audience and results of Candy Crush's marketing campaign.

Apple's recent iOS update made IDFA an app-level opt-in, so in order for this existing advertising mechanism to work, you needed to opt-in to tracking on FB (so they could associate your IDFA to a FB user) AND to opt-in to tracking on the other apps (so they could send ad networks data with your IDFA). This double opt-in obviously has a super low rate.

FB wasn't impacted nearly as much as other advertising businesses because they already have identifiers for their users (email, phone number, etc), have a ton of first-party interest/behavioral data, and they mostly run ads on their own properties. Apps who used third-party ad networks to sell and place ads in their apps had their business completely destroyed.

I think this is all fair in terms of user choice and to give Apple control of their own platform, but it opens Apple up for a lot of regulatory scrutiny given that they were able to flip a switch that annihilated a $50b mobile advertising industry, while making their own equivalent data collection opt-out (vs their competitors' opt-in). Even then, Apple frames their data collection option as "Personalize your experience" while forcing other apps to use the phrase "Allow this app to track you." Apple's own ads product has tripled its market share since this launched. [0]

This article might lead a reader to think that surveillance is in itself a problem, using terms like ‘invasive’, and ‘normalising’ (as though the thing being ‘normalised’ is undesirable). While it does appear to distinguish between surveillance and breach of privacy, it doesn’t do so carefully enough. What I actually want are devices that let me surveil MORE of my life, but in ways that respect my privacy, that leave me in control of that data. There are so many benefits that we can receive if companies/software/products were to offer us greater insights(/‘invasive surveillance’) into our lives without breaching our privacy or trust.

When I am surveilling my own life, with devices that only share my data in ways I happily consent to, there is no problem. I can reap great benefits through this. I can take photos of myself and my family. I can monitor my heart through a device on my wrist. I can write personal notes in a journal (whether on paper or digitised) for later reflection. I can keep a history of sites I’ve visited in my browser.

What a company like Apple claims to be doing is to try and bring us the benefits of surveillance without the breaches of privacy — without the forced and reluctant consent to share our data with everyone. Surveillance isn’t the enemy, it’s companies trying to make a product out of that data that really we’d prefer not to share at all.
I think, two entirely different topics became mixed up here: the privacy of point to point messages and the impact of algorithmic enhancement of public messages. To my best abilities, I fail to see a connection. (That is, you may suggest that the latter may lead to an increase of "problematic" calls to action in private messages, but, then, you've already messed up in the first place, by enhancing the impact of public messages.)
They're not considered necessities in the sense that the government has to, in general, provide you with a hookup at a reasonable cost.

Adobe extends Photoshop to the web
Hello all,

We recently launched Mutata.io, an innovative framework that enables iOS applications to run and release to Android without rewriting the Swift code.

After months of development, we are proud to announce that we have already released the first Swift applications to Android and we are currently looking for more apps to test it with.

Here are some of the highlighted features:

- Run Swift code directly on the Android device. Swift is compiled for both arm and arm64.

- Read design directly from .xib and .storyboards, so you can continue designing in Xcode and run it directly on your Android device/emulator. - Support for @IBActions and @IBOutlets.

- Support responsive layout using Constraints. Mutata will generate the needed ConstraintLayout and ConstraintSet from NSLayoutConstraints.

- Support most UIKit Elements.

- In-App Purchases support. For example, you can write code for In-App Purchases using StoreKit, and Mutata will automatically use the respective native functions to call the Google Billing System.

- Firebase support: Use the official firebase-ios-sdk for Auth, Realtime Database, Storage, Functions, etc., and Mutata will call the respective firebase-android-sdk methods.

In https://mutata.io you will also find our Showcase app built for iOS using Xcode and released without any code change to Google Play.

Still curious how this works? In https://youtu.be/AAgPpSKAS74 there are examples of how Mutata works and integrates with the Xcode to create Android apps.

I am looking forward to your feedback and questions about the tech behind it.
