Does anyone know how they track the position of the communication satellites? I assume they use GPS for the users position, the gyro and accelerometer for device orientation, and then periodically load and update the LEO sat paths on the device when they are connected. Or is the antenna able to estimate LEO position via a signal the LEO sats sends out?
Hard agree. I'm not a huge fan of cross-platform dev tools in general[1], but in terms of code hygiene, documentation, and "it just works" factor, Flutter is way ahead of React Native.

Admittedly it's more of a vibe than a hard metric, but a clean build of an empty React Native app for iOS has a triple-digit number of warnings in Xcode.

[1] Making a cross-platform app that's snappy and really nails the platform idioms tends to be at least as much work as making two equally-good native apps.
In a similar article we discussed a ring structure to store data. You could store about an L1 cache’s worth of data in a loop that’s roughly a nanosecond long.

Problem we didn’t discuss is this: L1 cache is less than 1/3ns on high end hardware, meaning that L1 caches currently have about 1/3 the latency of this light loop.

Once this doubles or triples again you might have a solution for L2 cache though, since chip clock cycles are relatively stuck.
Except that it's impossible to just use it as a currency without speculating due to the volatility (and I get that that's probably the fault of the speculators, but that doesn't change the reality of it).
First, I'd point out that there is a lot more acceptance now for "day rate" or "week rate." You can find its advocates in most contracting-related threads here on HN. If you are paid by the day, it doesn't matter if that's a 10-hour day or a 4-hour day as long as the client doesn't feel taken advantage of.

Nor should you be taken advantage of: I have friends in other industries where "day rate" is the standard, and it's a high rate but it sure does involve crazy hours when the project is in full swing. Ask a film editor about "work hours" and they will either laugh, or cry. Let's not normalize the 18-hour day!

Second, you should feel good about even worrying about this: it means you've got some ethics. But you shouldn't feel like you owe "flow state" for every hour you bill. Do you need to take a walk to clear your head and better concentrate on the problem? That's work. Lunch isn't that much harder: is it a working lunch? Bill it. Are you having a nice long lunch in order to not think about work, or maybe meeting friends? Don't bill it. (Day/etc. Rate obviates this problem.)

Third, socializing with the staff is a little complicated if you're billing hourly, or sometimes even daily. I would be pretty happy if a contractor went out for social food/drinks with my employees, but I would much prefer to pay for that in good will than in actual billed hours. On the other hand, if you're at one of those places with ping-pong tables and the SRE peeps really want you to play with them: bill it!

Mobile development is very fast-paced. Even with the native Android SDK, dependency issue can bite you. If I start working on an old codebase and I can't get it to launch in a few hours. I just generate a new starter project and migrate the codebase, adding the newer version of each dependency (while taking care of breaking changes and so). It can be easier and take care of security issue at the same time.

Desktop, CLI and Web Backend programs can be easier because they are in a much stable environment. But mobile development is very much a high-speed train.

My own tips for React Native is just use the IDE (XCode, Android Studio) for each platform whenever I have to build and use a text editor for the JS part. Always worked flawlessly.

The critique of advertising rings some bells; however, planned obsolescence is not always a bad thing because the advances in new versions might outweigh the energy necessary to produce a better version.

So something like a bread toaster probably suffers from planned obsolescence; LCDs (or generic display technology) likely benefit from planned obsolescence.

Before Telecommunications deregulation everyone had pretty much the same telephone that was leased from the phone co. It was electromechanical with sizeable transformers and magnets in there. Compare that to the sets that were available after deregulation with miniaturized components.

Basically it's not always cut and dried and there is nuance especially when it comes to energy efficiency. On the other hand, it's really annoying to buy kitchen appliances that are poorly manufactured.
Question: Is there a real number x such that x^2 < 0?

Answer: To explain, we need to define what we mean by "real number".

If we define a real number as a number that can be written as a fraction, then the answer is no.

If we define a real number as a number that can be written as a decimal, then the answer is yes.

If we define a real number as a number that can be written as a decimal, then the answer is yes.

If we define a real number as a number that can be written as a fraction, then the answer is no.

If we define a real number as a number that can be written as a fraction, then the answer is no.

Musk is "trying" to save Twitter after the $1B+ annual interest debt which he chose to saddle it with.

It's an interesting strategy so far, treating people like dirt and spooking the advertisers with his chaotic decisions, the net effect adds up to damaging Twitter's biggest source of cash — advertisment deals.

In another version of our timeline, Musk took the reigns and kept things running relatively smoothly while digging deep to actually understand the system and form a coherent strategy before enacting wide-scale platform changes. He's missed an enormous opportunity lead through an inspiring vision.

In our timeline, we have an immature fool making a very public mess. It's undeniably entertaining and stranger than fiction. But I feel terrible for the employees, real living breathing human beings, suffering at The Hand of His Royal Majesty.
Im confused by your position here, employees should agree with all decisions or leave? That’s not generally the relationship I’ve had with management or peers in my career.
"Band n53" has been widely reported in the context of various iPhone satellite rumors, but I still believe that this was actually just bad reporting: Band n53 is essentially terrestrial LTE/5G usage of Globalstar's global spectrum rights in a band that was previously designated for ground-to-space usage.

Whatever the iPhone 14 is using to talk to the Globalstar satellites, I'd be extremely surprised if it looked anything like LTE or 5G at the physical or logical layer.

The trouble with any such footage is that it can be used against you ("as the the defendant's own records show, they were present in the murder area") but they generally won't extricate you when produced by you, since you clearly have a motivation to use it selectively. So you showing a picture of yourself reading a book during what you claim is the murder night is not an alibi, because it could have been produced at any other time, and you will have a massive uphill battle in the court to authenticate that image, and risk even sink you further if you fail ("the defendant even prepared an alibi").

The only way I would accept a commercial product performing this always-on archiving is if:

1. It's encrypted by default with a strong key that can't be subpoenaed or circumvented.

2. The encoder generates its own random key upon installation which I don't know (recoding effectively random, undecodable data), and I then have to manually change the key if I expect to ever read the recording.

Number 1 allows me to review and footage and only release it if it's in my interest, and number 2 affords me plausible deniability, if I don't release the key I can claim I did not know you need to set it manually.

Sure, as long as you are the only nerd doing this, you don't need this complex setup, and you will probably get to use it the unencrypted footage only in your favor. But when it becomes widely accepted as a social norm (say, everyone wearing Google glasses), you can expect law enforcement will become aware of it as a cheap source of self-incriminatory evidence.
> if what we're starting to hear is correct, FTX may be one of, if not the, biggest financial frauds/scandals in history. The media doesn't seem to be treating it as such.

Yes, that era is fascinating.

In my understanding of the complex history of wireless/radio G Marconi's own business model was point to point communication disrupting the telegraph companies with the new and remarkable feature of being able to communicate with ships at sea. Remember that Marconi was Italian-Irish and his mum happened to be a millionairess with access to the highest levels of the British establishment (this is all 1900s, so before the Irish Free State). So immense investment in long wave point to point transmission by spark transmitters turning over to thermionic valves in 1920s or so.

Broadcasting was a sideshow for him but was central to the electronics startup scene in the US and UK. You go from homemade components in the immediate post war period to manufactured radios and then to consolidated electronics combines in about 15 years.

The early period was full of mavericks and slightly quixotic people. Later into the 30s you get the David Sarnoff's and consolidation.

Also for some context, related to China-Canada relations; there has been rumour that China has operated state run (semi-secretly) policing departments in BC and other areas of Canada and has forced people to return to China that were legally in Canada.

(I have no idea what Canada is offering in return for cheaper clothes.) {Probably some kind of natural resource.}
Well, for example. Lets say that I have a goal BMI I want to maintain

If I reach for the Oreos, I can choose to have a flag set with a heuritic I created myself that will tell me:

"Having 5 oreos means you need to reduce other calorie intake by n calories to maintain your BMI"

That data can also be aggregated to give me my macro/micros for everything I've eaten etc... without me having to log it like I do now

Think about it as the ultimate personal assistant and all you need to do to instrument it is attaching a camera and mic to your face. You can decide what your goals are, and this kind of instrumentation will capture the data that you need without you having to actually annotate everything.

Your personal life API
In my experience you bill what you can get away with billing while making the client happy. That may mean billing when you're not working, but it can also mean working without billing at all. The idea of time-based billing is pretty fuzzy when you get into the details, so it's better when nobody on either side tries to figure it out, and you just ship something that makes them happy.

In terms of negotiating a rate that makes you competitive, your idea could work, yes. The danger is that (IME) clients who were that budget conscious were also generally worse clients in general: less organized, less of a vision, less willing to do things like pay for user testing and support, generally more stressful to work with. Often their projects were less interesting, too.

At a certain point, my company just raised everybody's rates significantly, across the board, and rather than going out of business, we ended up getting better projects as a result. In that case, I was shocked to realize that software contracting can act like a Veblen good, though in an economic climate like this one, I'm not sure it would work that way.

> I swear I'm not tailgating people LOL

If you're going 40mph and approaching nearly stopped cars at <80 feet, you're absolutely tailgating people and creating extremely risky situations.

Don't get me wrong, I've had my emergency braking trigger for similar circumstances of someone turning into a parking lot off a feeder of a highway. But I don't blame my equipment, I acknowledge I'm not a perfect driver. The car knew it could have been quite a challenge to stop in time and so it took action. The better action would have been for me to be going slower and approach that situation with less speed, not to just blame the car for being cautious and forcing realistic safety margins.
My contracts are usually to design and develop new product for client. It is rather longer term involvement and I just bill them for 8 hours per day disregarding on what happens on any particular day. Clients know about it and it is agreed upon. If they are not happy about my work which luckily had never happened they're free to show me the door.

Every once in a while I also do short term contracts with very limited scope. For those I would just do a lump sum payable in stages or just initial deposit and then pay balance at the end.
PlanetScale is such a cool name, fits really well for a database company. Just goes to show that even these days when I think that naming something new is impossible, there is still a lot of room to be creative.
This reminds me a little of "materialized views". But essentially every query is potentially a view you can materialize (cache). And with this being managed at the DB level it knows when new data invalidated the previous results.

Traditionally, other materialized view implementations have very strict query requirements though. The queries had to be deterministic. No left joins, dates, etc. This is required in order to properly detect when data changes "impact" the view. I wonder how they get around it.

Update: Ah, ok! Here's a write up on how it works a bit. My last startup built a system like this specifically to power a gamification engine. Would have been nice to have this 10 years ago.

https://planetscale.com/blog/how-planetscale-boost-serves-yo...

> The Boost cluster lives alongside your database’s shards and continuously processes the events relayed by the VStream. The result of processing these events is a partially materialized view that can be accessed by the database’s edge tier. This view contains some, but not all, of the rows that could be queried.

Mental Health Apps Are Not Keeping Your Data Safe
I think the title is using the word 'inevitably' where they mean 'eventually' or 'ultimately'. It's not inevitable that people who invest in Bitcoin lose money, for example, they could have changed their mind and sold then next day, making it avoidable. What they mean to say is that most people who invest _end up_ losing money, not that it was unavoidable (the meaning of inevitable).
Well, genius borders madness, and it's been said that talking to oneself is a sign of intelligence, so you may be right.
React Native is a huge PITA. It’s not worth it for a one person dev team. Try flutter. I highly recommend the appbrewery video course - it’s $10 and teaches you everything you need to know.

Typing this from my Fedora based workstation, been daily driving Fedora since switching from RHEL 8 to Fedora 34 last April. As I don't work in or use Ubuntu-ecosystem-centric tools (this was a PITA when I was working on a RHEL 6 based HPC cluster) I don't really run into any issues. And for applications if there's something not in the primary repos (Fedora + RPM Fusion) there's typically a Flatpak covering my use case.

On top of that, Google is now requiring that you keep within 2 versions of the latest API, meaning that you have to reupload your app every 2 years (or less) to keep it on the store. Even if it's completely fine.

I think there's something similar for Apple, but I can't actually remember the details right now.

That's really not "all there is" to intersectionality. You are repeating the motte-and-bailey of far-left ideologues wherein you fall back on the official/original definition of the term, conveniently ignoring that its meaning has changed over time, and has been coopted.

To be clear: I'm being charitable in my interpretation, and assuming you are not intentionally doing this.

Individual investors usually have terrible investment habits. They buy trendy stocks after hearing about them on the news, and then sell after they crash

This same crowd gets interested in Bitcoin at every ATH because of the news coverage. I got so many people asking me how to buy Bitcoin when it hit 20k in 2017 and 60k in 2021. That's when the vast majority of people buy.

Yes, if you put money in your 401k and don't take it out until retirement you will make money. That doesn't describe the vast majority of investors though
> If you just use cryptocurrency as a currency there's no problem at all.

Exactly, and then you realize there is a lot more difficulty using crypto as a currency than actual currency, and then think "that was dumb".

I'm probably one of the few people who has actually purchased real (legal) stuff with crypto (at least in one of the only ways that was really feasible at the time - converting crypto to a gift card at a real store). I remember waiting in the furniture store for nearly an hour hoping for my block to get confirmed to purchase a sofa. "Gosh", my non-tech spouse commented sarcastically, "this really is so much better than a credit card swipe where I'd be done in 10 seconds."
There were some critical flaws in the logic though. The risk calculations for the synthetic CDOs that mixed the lower tiers of loans and that diversification magically made them suddenly prime ignored the possibility of any kind of event that would affect the market generally; say a recession or in this specific case lots of adjustable rate mortgages changing to higher rates when the initial rates expired? The idea of creating an instrument like that is fine but the analysis of the risk and the layering of them together created an impossible to analyze time bomb.

Also no one sold me a CDO gun they sold someone else a gun and it threatened to sink the global economy riiiiight as I was going into college. Luckily software engineering weathered the period fairly well and I was able to get a job when I graduated in '13. These things don't just impact the buyers and sellers they incentivize and potentially warp the entire economy and when the sellers and buyers screw up they're not even left holding the bag.
