Innovation isn't very likely to be found in a sterile corporate environment.

The attempts by Meta to control so tightly what content ends up on the Quest will only end up with results that are a reflection of their creators.

I felt like i wanted to throw up with the whole bay area, corporate environment vibe this presentation gave off.

I was most excited by the prospect of having Xbox game pass on this thing until i found out all it is is a big screen in VR (What's the fucking point, guys?). If they have the engineering resources to convert even a portion of fan favorites into native VR experiences, that's going to kill.

This feels a lot like IBM labs where the technology is "there", but these clowns are not the ones who're going to find the killer application and yet are hell bent on controlling the whole thing.

Someones going to come around eventually and hook this up with porn, native video games, psychedelic experiences in legal states etc and push the boundaries of exciting yet controversial content that would never get past the committee of corpo minded rats at Meta and that will be when it takes off.

For their sake, i hope Meta realize this.
I appreciate that the article is written to be readable to a wide audience. But:

> But ultrafast ultrasound is exponentially faster, more powerful, and more spatially sensitive than standard ultrasound: It can produce many thousands of detailed high-resolution images per second.

is there any way to stop this weird mutation of the meaning of the word "exponentially"? Probably not, I guess. I trip over it when reading: "Hmm... so it's exponential in... oh, dammit, they just mean 'way faster'."
They opened a company in Serbia so I guess that some of the Russian employees already moved to Belgrade.
I hear this a lot but this is way too caricatural.

For one, commercial services will go through SMS to contact you. Delivery people asking if my mailbox can fit parcels won’t be through Whatsapp or Messenger.

Then you’ll also want to compartmentalize and limit how some people can reach you. That means if you’re already giving them your phone number, you don’t want them on the other messaging services as well.

Life is complicated, and there will be endless use cases for the baseline, default messaging platform.
How do you know if your contacts use Signal and know to use that app instead of SMS/Messages or whatever?

With the SMS integration it was pretty easy because it would just switch over if the other person had Signal or if/when they signed up in the future.

What's the workflow now? Manually ask them on SMS if they use Signal? Just try it and see if it works?

This sounds like one of those "Don't Worry! Rejoice! We're breaking your things!" announcements that hasn't even thought about how people use Signal IRL.

I'm going to stop my monthly subscription to Signal Foundation.
Honestly I'm a little disappointed by the lack of enthusiasm for what this could be; people shat on all kinds of now-ubitquitous tech with similar "nobody will ever replace the typewriter!" kinds of arguments.

It would be cool if we could solve the hardest part of interacting with others remotely, which is the lost fidelity. That's an interesting and hard problem that we haven't yet totally solved.

Meta isn't there yet, but they're trying! I feel like the corpo-hate has overshadowed the positivity that used to be more prevalent in the tech community.
You get what you pay for. To find the useful information among the pile of what you call pedantry and nitpicking you have to not take any of it personally and not assume motivations of the people who post answers. Skip over the non-responsive and off-topic replies, and remember that someone took the time to respond at all, for free, and may have simply misunderstood the question or answered it from a different frame of reference than yours.

Consider that many questions posted in online help forums don't seem to have much clarity or effort to express the problem. Many questions already have answers, which makes those who do try to answer wonder why the questioner didn't search first.

When asking strangers for free help online you don't have the right to demand anyone conform to your definition of useful. You don't get to set the terms. If you want to set the terms and get only helpful answers you will have to pay experts.
That particular niche has had some pretty amazing successes already. It's coming.

We can't produce arbitrary media streams with many "stack layers" of meaning and detail yet, but we can do a lot of specific instrumental transformations...

If jumping in and out of VR is the desired business case, apps would just let you switch to audio only mode, when you pull off the headset or alt-tab or if you disable body language sharing.

Love the post. I'll take this opportunity to link to a favorite classic linear algebra paper in a similar vein: "Nineteen Dubious Ways to Compute the Exponential of a Matrix" [1]

California is building desal plants, Look at the one built in Carlsbad, CA that went online in 2015.

The problem is price. From the wiki[1]:

> "The cost of water from the plant will be $100 to $200 more per acre-foot than recycled water (approximately 0.045 cents per gallon), $1,000 to $1,100 more than reservoir water (approx. 0.32 cents per gallon), but $100 to $200 less than importing water from outside the county. As of April 2015, San Diego County imported 90% of its water."

Considering SD imports so much water, this is a big win. But still, this one plant cost nearly $1b to complete, and only provides 7% of the potable water for San Diego County. It's a non-trivial cost to use Desal water vs recycling efforts and loss prevention from reservoirs.

So...let's just call it sexism?
They say “opportunistic” as in similar to how iMessage works. If you’re both on the platform, it’s encrypted but you still can communicate with everyone else from one app.

That’s a major boost for those that might not particularly care about encryption to look for specific messaging apps, while still helping by building out the network slowly over time.
Thank you for this summary, I recall Dr. Oshmyansky when he first went into the PhD curriculum, time really passes you by when you forget to notice it.
I don't mind autotune as an artistic effect. I'm not against Daft Punk. But, I can't stand to listen to very much rap after M.F. DOOM because it has all been infected by T-Pain. Personally I can hear the effect that "subtle" autotuning has and I don't like it.

The fact is that "wildly successful" today is against a background of reduced expectations. Thriller sold 70 million copies, Bat out of Hell (somehow) sold 43 million copies. That's on a different order of magnitude than what seems possible today.

I think part of what makes music interesting to listen to is the subtle imperfections and nonidealities. It hurts to listen to a pure sine wave but FM synthesis adds some richness, as does the three strings on a piano that are just slightly out of tune. Numerous artists that were productive and commercially successful in the 1970s failed to make a transition to the "music word processor" in the 1980s. They kept releasing albums but fans ignored them and will boo if they try to play anything but the old favorites. I think MIDI and the click track are part of the same problem as autotune... "Snap to grid" and a lot of what makes music interesting is just gone.

My bank is already regulated and required to have strong identity verification for some operations. They won't let use any sensible multi-factor authentication, however. Requiring they use such a government mandated authentication infrastructure would be a major "win" for my piece-of-mind.

You assume that laws are moral to begin with. Remember, slavery was legal in the United States, and the Nazis made laws to deprive Jewish people of their rights.

Conversely, not all immoral acts are illegal, e.g. cheating on a spouse.
Tell HN: How to get Paid Support for Gmail account
Seeing a lot of stories about People getting locked out of Free Gmail and google providing no support, I thought to share. They have a "Google One" plan which you can buy for $1.99/Month or $19.99/Year to upgrade storage etc but it also adds Direct Support for Gmail, storage etc. This could be useful if you rely a lot on your Gmail account.

You found a bug that potentially allows strangers to invade the privacy of others. My personal opinion is that you have a moral obligation to report it to the manufacturer and give them an opportunity to patch it before releasing anything publicly.

Not disclosing it is putting countless people at risk. How would you feel if someone looked into your house and was able to see you and your family members in situations where they were expecting privacy? You have a chance to prevent that.

Don't put others at risk for your own convenience. Doing the right thing is never the wrong thing.
+1 to this. If Signal drops Android SMS support, I suspect it'll create friction within my friend group that uses it. I do not want yet another app for just text messages. No thank you.
funny enough yes I did. A school was looking for an IT admin and I got the job and after a year the headmaster asked me to teach too
They'll just call it the "Ad Light" tier then.
Yeah, I think this is more likely to be the case. People who don't understand encryption but used Signal as their SMS messenger were at least getting opportunistic encryption with any of their contacts who were using Signal. Now they'll probably just uninstall it (like every iOS Signal user I've ever known).

Well, no. Straight down is possible, but not necessary or even necessarily likely.

I think there's relatively little empirical evidence with respect to relativistic collisions at macroscopic scales, but isn't there a simpler conservation of energy argument to be made? Absent fancy orbital mechanics maneuvers, isn't the upper bound of the 'planet killing' energy of impact the total energy imparted by the accelerating lasers?

Or am I missing something (could be physics was 30+ years ago.)
Obligatory addition: Google’s version of RCS is just built on top of an open standard but is hardly more open then apple’s imessage so adopting that is not a solution either.
In resume, the night of 8-Aug, in full touristic season, a 19 Yo man alone was able to cut the high speed train connection between Madrid and Barcelona for five hours, creating chaos in the train stations with more than 12.000 passengers affected that should be rerouted that morning
I'll just go back to Android. If my only options are adware companies, I might as well get the cheaper product.
Bad move. They should be expanding support to include RCS (which can support e2ee, although I don't know if it's at the provider level or at client level).
Which is all to avoid having to admit you're in a recession to avoid the self-fulfilling prophecy aspects of that.

Economists, of course, have a lot of pressure sometimes to avoid speaking the truth, lest they exacerbate the situation. I get that.

Again, I'm not concerned that we're "going into a recession." I'm concerned that we're going into a depression, or decades of stagflation, or war.
> 1. Inverting a Matrix

Possibly only a partial sin since I use Moore-Penrose pseudo inverse and L2 ridge regularization. This sin is being commit as a consequence of committing next sin.

Yes yes this is potential numerically bad. However in practice as long as you are careful with scaling it’s perfectly fine and enable better parallel computations.

This sin is the only way I actually know so after reading this I realized I need to read more on this.

I definitely have code that should he changed. It’s also on my todo list now to audit a specific routine that I suspect can be fixed. This one is just stupid it can be avoided.

While it may, I fear (and having seen this in other places) that this would lead to some entitlement by the person asking the question seeing it as a personal help service instead of trying to build a repository of information.

As someone who might answer, the related part would be "I don't want to be waisting my time duplicating work that someone else is doing."
I don't think that's true? There are clearly users who are annoyed at being able to send insecure and possibly expensive SMS messages in their secure messaging app.
Apple does not seem to think this is a problem. Their default Message app supporting both SMS/text and iMessage. They have an opt-in to send via SMS if iMessage fails and this gives it more reliability too.
There used to be more positivity because it was genuinely about making great products that people will like and want to buy, instead of making something people will like just enough to let you datamine them for all they're worth.

Is this seriously anything beyond Facebook trying to get companies to mandate using these so they can get high fidelity 3D video footage of every living person's house and apartment, their gait and all other possible biometrics? I certainly wouldn't put it past them. Quest headsets are cheaper than all other headsets for a reason.

> That's what is nice about signals implementation is it stands.

Sure they handle SMS, but the real problem here is that Signal is just another walled garden: they have an overtly negative stance towards alternative clients, while also having very bad support for anything besides android/ios: they have a bad desktop client and they don't have a nice library. Altogether this means that Signal is overtly and willingly against things like Pidgin / multi-protocol clients or overlay, which is what the users want (ie not caring about protocols).

Signal doesn't want to deal with SMS anymore, which from an engineering and high-stakes security pov is a completely valid decision. Yet if it had clean and open local API or a simple and portable client library, or had a stable server API, then someone else could provide multi-protocol clients, tailored to each platform in a secure and stable way.
I've been using Signal for a long time. I have repeatedly been unable to convince iOS users to use Signal because "I don't want another app". Android users have been much more willing to give it a shot.

As an android user myself, I much prefer having SMS built in because I use the search feature often to look back through all my SMS/Signal chats. I also regularly forward an SMS message to a Signal user, or vice versa. I'm already starting to feel like those iOS users who told me "I don't want another app"...

Signal seems to be trying to move further and further from "my preferred way to chat with people" and closer to the chat equivalent of "that protonmail account I only log in to when I need secrecy".

I obviously love having security on messages in transit, but I also like being able to keep my message history around and search my conversations for something that happened a year ago. It seems like Signal is on a trajectory to turn everything into disappearing messages. Are they the "safe for activists" communication app, or the "let's try to make as many as possible safer by default" app? Feels like they don't know.

And on top of it all the messaging is just frustrating. "we've taken away an incredibly useful and heavily used feature so we have development resource to better implement shitcoins and such" is such an irritating defense of the decision that I disabled my monthly donation.
im surprised by all the tech readers here saying this is bad. do y’all not care about privacy? the main reason is sms compromises that

> Someone drank a lot of propaganda... proving my point again...

Did Russia not invade Ukraine? Is there some hidden history that the US managed to hide where Ukraine invaded Russia first and everything we're seeing from every firsthand source is wrong?

Like, this the modern world where civilians, soldiers, everyone can post to the internet and share what's happening. And all these sources taken in their entirety support the Ukraine narrative, definitely not the Russian narrative. And maybe you need to watch MORE Russian propaganda just to get an idea of how incredibly absurd and detached from reality it really is....

> I don't use my phone to log in to anything. All my stuff is done on a computer with a password manager.

More or less the same, except that I haven't found good TOTP solutions for the desktop, to the tune of KeePass (something that can run on Windows/*nix instead of making me use something like FreeOTP, Google Authenticator or other Android/iOS apps; or in addition to the mobile apps).

That said, even with multiple Google accounts for different things (e.g. personal e-mails, file storage, cloud services etc.) it feels like eventually you might want something like Qubes OS, another way to run multiple separate VMs, or just use separate devices for separate use cases.

Much like how some orgs have separate laptops for accessing prod environments, that are more tightly controlled, even though that's not convenient enough for most people.

This isn't the same.

Very otherwise upstanding people will absolutely talk behind people’s back about that person’s green bubble pollution.

People go on to mock the sales pitches android users use since everyone’s heard them ad nauseam for a decade

They are generally making deep assumptions about people’s decision making process if they have a choice in phone model, and making conclusions about that person’s socioeconomic class if they don’t have a choice in phone model

And it all ends with a laugh about how most android users live their life without knowing this is happening, but that reinforces the perception of a lack of self awareness and inability to pick up social cues

Science looks for predictable facts.

They're as different as chalk and cheese.

However, people do science, so, they're gonna have philosophical opinions. But you can do science without philosophy and contrawise.

Or do you mean the ontology behind science? Asking where knowledge comes from?
