Would be interesting if this evolves into a full filesystem implementation in hardware (they talk about Object Drive but aren't focused on that yet). Some interesting future possibilities:

- A cross-platform filesystem that you could read/write from Windows, macOS, Linux, iOS, Android etc. Imagine having a single disk that could boot any computer operating system without having to manage partitions and boot records!

- Significantly improved filesystem performance as it's implemented in hardware.

- Better guarantees of write flushing (as SSD can include RAM + tiny battery) that translate into higher level filesystem objects. You could say, writeFile(key, data, flush_full, completion) and receive a callback when the file is on disk. All independent of the OS or kernel version you're running on.

- Native async support is a huge win

Already the performance is looking insane. Would love to get away from the OS dictating filesystem choice and performance.

>my phone survives much longer when there is no network

Interestingly I've had the opposite experience (with a Pixel 2 XL, and before that a Nexus 6P). With both phones, when going on out-of-service hikes the battery drained significantly faster than usual -- despite not using the phone at all, I'd see a 40-50% power drain over ~8 hrs. Putting the phone in airplane mode when I knew I'd be out of service solved the problem, as expected.

> The article mentions that the delta-v on the chart is required to go from the surface of Venus to a low Venusian orbit, not the other way around

Delta-v is symmetrical. Putting something in orbit is mostly about accelerating tangentially to the surface, not about going up. Taking something out of orbit is mostly about accelerating tangentially to the surface, not about falling down.

> I'm pretty sure that a probe in a low Venusian orbit would decay on its own just like they do in low Earth orbit

Orbital decay for small objects is slow aerobraking. It is slow, requires a heat shield, and is structurally stressful.
Ask HN: What is the worst (technical or business) advice you've ever given?
lol what so you got $2500 for free?
Your advice is good in most circumstances, and may end up being what we do.

In any case the mode I cooked up has after a few minor tweaks essentially converged with AES-(CMAC|PMAC)-SIV but with GMAC in the MAC slot and with an extra AES-ECB (AES as a 128-bit keyed hash) step after GMAC to make it into a proper PRF. If that's the case then it seems that the AES-SIV work and papers apply.

I was reading about AES-GCM-SIV and it's unfortunate that they decided to use a new MAC digest function called POLYVAL instead of GHASH/GMAC. If they'd re-used GHASH/GMAC as-is it's possible that AES-GCM-SIV could be described in terms of GMAC and AES-CTR and therefore could pass FIPS. I guess nobody but people trying to sell to certain parties cares about FIPS, which is probably as it should be because FIPS sucks.

https://tools.ietf.org/html/rfc8452#page-17

Edit: it looks like POLYVAL is GHASH optimized for little-endian machines, so I see the rationale. Still too bad. They missed a bureaucracy-hacking opportunity.

I'm not an expert on small business loans, but I would guess that incentives take care of most of this problem. The higher the loan you have, the more cash your business must have been generating in the first place, therefore the higher incentive you have to figure out how to keep it running. There probably aren't too many scenarios where you are both eligible for a material loan from Stripe and yet not highly enough incentivized to figure out how to make the business work to the best of your abilities.

That's pretty dumb. Car2go (Vancouver) has keys in the glovebox in a special holder-device: you're free to take the keys with you if you want to keep paying for the car as it's parked, but it won't let you "end session" or whatever unless the keys are replaced into the holder thingy.

This article is terrible. The change mentioned in the headline isn't explained until the fifth paragraph and beyond.

> Apple’s change involves an API called PushKit, which was originally designed to be used in apps that let people make online phone calls using voice over internet protocol. .... Over time, many apps began using the tool for purposes other than Internet phone calls, including encrypted messaging apps that found it was the best method for decrypting messages in the background on iPhones. .... But app developers could also use PushKit to collect information about the location of users and other sensitive data, which concerned Apple. .... With iOS 13....the company is finally cutting off developers from using PushKit for any purposes other than internet phone calls.

It may be string comparison on the JS level.

However If it is string comparison on the TS level then that means it isn't type checked. Are you sure this is what you mean? That means I can add a new case for string "asdasfsdfds" and TS won't throw a type error.

The variant type is not exclusively an FP paradigm.
I actually think it's a strange but probably a solid strategy under a couple of assumptions:

1. They want to differentiate their dating product.
2. There's a sector of the population interested in dating but that at the moment is underserved, too shy to try it, or just on the fence about putting the effort to try it out.

What this does is it essentially puts a dating app on everyone's phone, reducing the friction it takes to give online dating a shot.

It also "feels" different and more serious. Anecdotally Facebook seems to be, amongst my circles, a lot about life events or important stuff and less about the casual, funny, edgy, etc persona. By associating that image with their dating platform, they give it a strong identity for the get go as a place for serious relationships.

> Even announcing this through the instagram brand would have made more sense to me.

Would it? I feel like Instagram is better off being about friends and oneself, and it could be tarnished by involving dating. What dating "identity" would befall upon it? Would it lean on the side of Tinder— superficial, more about hookups than long-lasting relationships, etc? I associate instagram with influencers, young people (as in, teens), etc a lot so branding-wise it doesn't make that much sense to me personally, though of course, this is just my opinion.
I was thinking that too. Makes you think of a 90s sitcom.

Apple Music on the Web (Beta)
One thing I think is forgotten or neglected, particularly when you are a startup, is to learn your tools. If there are too many, cut down on them or isolate it’s code impact. Having too many tools/frameworks around increases the level of cognitive load and how to use them thoroughly. I’ve seen too many times where there are several different tools solving the same general problem interfere with each other because the coders don’t know that one would be enough.
Thanks for the pointer. I will certainly explore if that works well with a hosted gitlab instance.

I understand the value of static code analysis very much. Alas, I cannot start talking about things like cyclomatic complexity of code, or water-tight dependency mitigation and its impact on quality/cost-to-company/risk, as the audience isn't mature enough to really grok it.
My wife and I use Life360 every day for giving us notifications whenever we leave work, arrive at home, arrive at our kid's school, etc.

I will be very annoyed if Apple's changes break tools like Life360. I opted into the tracking for a reason. I don't need Apple making privacy decisions for me. I'm more than capable of making the decision myself.
Hasn't it been doing so for billions of years now?

Apple Music Finally Launches on the Web
I think Facebook's biggest strength is local communities. It seems to be the best place to generate interest for events and new businesses and it seems effective.

I can't imagine local newspapers are anywhere near as effective.
With Facebook's embracing of machine learning and their very deep dataset of personal information about users, this could be quite an amazing user experience and quite a terrifying prospect for privacy.

Facebook has a wealth of information on social relationship interactions and also on personal interests. Adding in information on romantic relationship interactions will allow them to (eventually, when the ML models are well-trained) provide amazing matches for users. The downside is that they'll now have a deep understanding of yet another aspect of your persona.

What are the dangers? How can they monetize this new relationship knowledge?

* Life insurance companies might want to know if someone is prone to date adrenaline junkies and be easily coerced into participating.
* Insurance might want to know if someone "hooks up" frequently, which could indicate that the person is at risk of medical problems OR has issues with impulse control.
* Dating profiles often match people by self-reported social activities like doing drugs, drinking, etc. That might be of interest to lots of companies.
* Relationship going well? Expect to see a lot of ads related to co-habitation (joint checking accounts, moving services, etc)
* If the dating service has a "feedback" component to allow people who go on dates to give information on aspects of the other persons personality, facebook might get information about a person that they don't even realize themselves and thus don't self-report. Such as the other person dresses badly, smells funny, needs dental work, tips well, etc.
* If facebook determines that you tend to fall for a certain types of physical traits, ads featuring models with those traits will become a thing.
* People don't give facebook every bit of information about themselves, but they do give it to dating services.

Think of all those questionnaires that ask about your opinions on abortion, if you want to have kids, if dating someone with different political beliefs is a hard pass, etc. Dating services use it to match people up who might be compatible, but Facebook will use it help advertisers get even more granular controls over their targeted users.

Even worse, if Facebook wants a certain political party to win, they could match up people who are firmly established in the political party they choose with people who are on the fence in order to let the dominant personality win.

> I think Facebook's goal is to make it so that you have one persona you show to everyone. To me, that seems like a cultural thing unique to Silicon Valley that the rest of the world does not necessarily want.

I disagree with this characterization. I live in SV and literally everyone I've talked to about privacy/anonymity on the internet sees the value in being able to partition one's life into different buckets for different audiences, and many of them actively maintain such partitions.

This has nothing to do with culture; this is about technology limitations and laziness. Companies like FB want to make it easier to track people online and tie everything you do to a single identity. They can certainly do a lot to link supposedly-unrelated personas through various forms of fingerprinting, but it's never perfect, and they'd love for things to be simpler.

There's also the issue of anon/pseudonymity: companies like FB don't like that because they want an indentifiable real-world person to be accountable for the things they do online.

(Really, think about it: the idea that the people who live in Silicon Valley have some magical weirdo culture where social and professional partitioning doesn't exist... well, that's absurd and doesn't even pass the smell test.)

I think you're overstating the use of "algorithms" in these apps. They just throw people at you that you haven't set up any filters to avoid seeing, and vice versa. The algorithm appears to be "people you didn't explicitly rule out based on a small handful of criteria you provided, and they didn't rule you out too".
The problem is that users can’t meaningfully make that decision. It’s especially bad when the app says “you need this for message notifications”, but then uses it for tracking.

I feel like an API that let you provide an XPC service to handle incoming messages, but restricted that service’s access to any device info, would be the best solution.

I have no idea how feasible it would be to make such an API.

The most active area of R&D in the storage industry at the moment is stuff falling under the umbrella term "computational storage". Everyone is looking into ways to make SSDs smarter, and move some processing closer to the storage where it can be done more efficiently or at least free up CPU time.

Some of the companies making enterprise SSD controller ASICs have decided to throw in extra ARM Cortex-A53 or similar cores for the customer to put software on, giving the application access to the data without a PCIe bottleneck. Some companies are putting machine learning accelerators on the SSD. Some are adding dedicated compression or crypto engines to transform data at wire speed. Some are just putting an FPGA on the drive, or implementing the controller on an FPGA and leaving leftover LUTs for the customer's use.

Almost any idea you can come up with about how to move storage hardware past the hard drive-like block storage paradigm has been at least prototyped and demoed at Flash Memory Summit.
Or Apple could make a better messaging and notification system that's similar to pushkit but without the supposed "sensitive data", or just fork pushkit to have a "low permission" version of it.

Slack isn’t a messenger app. It’s a platform. People like to “work” in slack for some reason. not that slack is so well suited, but because it reduces the number of context switches you need to do. it’s good to have something as a central hub.

If you produce some kind of app, you’ll want to integrate into a messenger platform and your choice (if only one) will be slack. this gives slack gravity and that is what makes it special.
