> But what’s exciting about RCS is its native support for extensions. Google has taken advantage of this ability to implement its own plan for encryption on top of RCS using a version of the Signal protocol. As of now, this only works for users who are both using Google’s default messaging app (Google Messages), and whose phone companies support RCS messaging (the big three in the U.S. all do, as do a majority around the world).

A big factual error. RCS is supported by hardly any carriers globally. That's the reason why Google managed to take over the whole RCS ecosystem, running their own servers in place of the carrier's ones. Google has also choosen to rule over RCS with an iron fist, shadow-banning users at the slightest perceived violation [1].

It does not even seem to be public knownledge whether or not Google would allow generic RCS clients on their servers, but the fact that they shadow-ban those who run their proprietary implementation on a rooted device, is not exactly promising.

I am not sure why an organization like EFF should root for RCS in its current state.

> Data isn't free

The adtech industry made data and its processing not just free (as in more than covered by the ad revenue) but outright profitable.

This is frankly a one-in-a-lifetime gift to the government because we've not only built an unaccountable industrial-grade spying machine but the government doesn't even have to pay for it as it pays for itself and incentivizes its own expansion.
> Large-scale quantum computers are capable of breaking all of the common forms of asymmetric cryptography used on the Internet today.

Is that actually true?

I was under the impression that there exists quite a large class of trapdoor functions (functions that are one-to-one maps, cheap to compute but whose reciprocal is crazy expensive to compute without some sort of oracle-like information) that could not be attacked by quantum computers?

Are there no asymmetric algorithm that are impervious to QC in use today on the internet?

Or are they specifically talking about the fact that RSA-style algos are vulnerable?
My life is so sweet and easy.

It's terrifying working around fintec and seeing how many 20MLOC monoliths are laying around and the code quality issues that crop up in them.
I wonder if the 23% were largely bots? If so that may be why the experience feels better despite the metrics? (The people I follow, Paul Graham and others, seem as active now as before. Maybe daily active users isn’t a thing to maximize?)
> 2 Size. While the US economy’s size is over $21T, the stock market (here we use the S&P 500, SPY, as a proxy) is at present worth approximately $40T, so nearly 2x bigger. However, the stock market’s value can fluctuate significantly. In a downturn, the stock market’s value can converge roughly to the size of the overall economy.

This is total an utter garbage - I stopped reading after this; they seem to be confusing different units of $'s.

My house is "worth" 15x my "income" and my "income" is 1/25th of my net worth (and was 200x my net worth when I was 25). There are times these numbers may converge, but it wont tell you which pair of underpants I have on that day.

They could have made a point about prices vs earnings - which gdp / market cap would give some measure of (if you believed that the stock market was a reasonable measure of the market cap of the country) which is almost certainly what the Buffett metric they go on to mention would be motivated by.
As pointed out, it's not compile time but runtime here unless I'm missing anything. And it would be a good reason to build a Credo check exactly for this (I've done a bit of research about this).

Any calls to System in regular compile time config (e.g. config/prod/dev/test or included) should be forbidden, same for attribute-level / meta code.

I hope we will get this one day!
I might be missing something, but I don't think you even need Hashlife for this. The pattern is regular enough that you could just flat out store a static (x, y, t, state) map of a single cell and apply it fractally in order to compute the state of any part of the map at any time in constant time. You don't even need to simulate it at all.

You were at Google at the time, but your memory of the ordering of events is off. Google used HTTPS everywhere before Snowden.[1][2] HTTPS on just the login form protects the password to prevent a MITM from collecting it and using it on other websites, but it doesn't prevent someone from just taking the logged in cookie and reusing it on the same website. That was a known issue before Snowden, and Google had already addressed it. Many other websites, including Yahoo, didn't start using HTTPS everywhere until after Snowden.[3] I know because this was something I was interested in when using public WiFi points that were popping up at the time. I also remember when Facebook moved their homepage to HTTPS.[4] Previously, only the login form POSTed to an HTTPS endpoint, but that doesn't protect against the login form being modified by a MITM to have a different action for the MITM to get your password, rendering the whole thing useless.

What changed after Snowden was how Google encrypts traffic on its network, according to an article quoting you at the time.[5]

I've worked places where they had so many databases from M&A that half of their FTEs were wholly preoccupied all year with performing outstanding DB maintenance: fixing backups, doing storage management, patches, applying move/add/changes.

For them, managed DBMS was a life-changing event. As soon as they had RDS or even Azure SQL MI, they were begging the cloud team for more, so they could get their team back.

In some businesses, it's definitely not a big loss to lose agility by having a large portion of your team tangled up in infrastructure management, but for some businesses, that constraint is an impediment to their line of business. Some businesses are missing opportunities for want of infrastructure being able to move fast enough.
I think it depends what you mean by "tracker." If you mean a financial instrument that you can get returns out of, probably not (this is by design, and almost certainly a Good Thing). If you mean a thermometer for the "health" of these types of companies, you're probably going to end up looking a lot at employee/consumer sentiment. Most people in the US are employed by these small private companies so in aggregate they are probably the best source for whether or not things are going in the right direction.

I also apply the Shirky principle at larger scale when solutions have become an industry, e.g pharmaceutical industry.
My subconscious reaction when first zooming in was: “f—— you.” They’ve taken something I’ve been familiar with for 20+ years and completely blown my mind. One of the coolest things I’ve seen on here in a long time.
I don't think anyone really answered your question. I work at McKinsey and can try to provide an understanding of how we add value. I have a PhD in computer science from a T1 university, so I'm not exactly the MBA type; but I am on the exact same track as them as a generalist consultant (called integrative).

Here are the good parts:

1. We are pretty good at being translators. For companies I serve, making sound business decisions requires understanding of the technical details. However, most of the time, the C-suite will not dive deep into them (most have no time; some just refuse to learn). Our job is to distill the complex topics into something that is digestible for everyone, and I mean everyone. The time spent by an analyst or associate is mainly on slide-making for this reason - there is a lot of iteration until the message and storyline are perfected.

2. We provide a voice for the technical working teams. Pretty much every project I worked in, the technical teams have a pretty good understanding of what they can do and what they need, but this doesn't always get heard by higher-ups. Part of our job is to relay these thoughts (again, in a digestible way) - anonymously if need be. Most of the time a representative of the client team also joins our C-suite discussion, which is a great career opportunity for them.

3. In addition to point 2 above, when the technical teams don't know what they need, we build out a plan for them. I built financial models, workplans, capability assessments for e.g., cloud migration for automotive part manufacturers (i.e., high-tech but not necessarily computer savvy companies) directly collaborating with working teams. They can then use these to present their case to higher-ups, enabling them to actually get what they need.

4. We have an understanding of the industry overall, because we go around and see what's happening everywhere. In order to prevent unintended spillage of company secrets, we get "conflicted out" of working with direct competitors when we serve a client, but we can work with different parts of the supply chain. We also have industry experts, internal and external, who can provide insights - which is sometimes very critical to get up to speed quickly.

The burnout is also real, and I am actively trying to move on to a "real" tech job after approximately 2 years at the Firm. But positive client interactions are very fulfilling, and I have learned so so so much about so many different things, it's incredible.

I'm also pretty lucky to have worked mainly in growth or go-to-market strategy. I have never laid anyone off, never led to someone losing their job whatsoever (I actually kinda did the opposite once by helping them overcome a PIP), never participated in political battles, and never did anything that could be considered unethical like the Purdue thing. Just solved cool business problems for tech companies for 4-8 weeks at a time.
This is indeed funny, but the 'tribune' role of finding bad law/process and advocating for its removal is missing from most government, corporate or otherwise, and that's bad.

It is in fact the same phenomenon as treating +SLOC as a proxy for productivity. When everyone is rewarded for adding process, but it isn't anyone's job to remove it, a system inevitably ends up with too much process.
I hear your pain: if boundaries are not correctly established, it can be problematic, as with any "boundary/interface" system.

Finding the right spot is indeed important here!
The mass processing of food could be the additional mechanism allowing mass distribution of prions, no?

Through processed foods, an apex predator like humanity comes into contact with proteins from several orders magnitude more animals than our ancient hunter gatherers or farmers. This problem is compounded as our livestock eat processed foods themselves.

Perhaps prions were not as dangerous for most of evolutionary history as they simply lacked a distribution vector?
When I was diagnosed with a neurological condition that was having mostly physical symptoms, the first-line defense was antidepressants. So-named because they were developed to relieve depression, but really what they do is inhibit absorption of serotonin and/or norepinephrine leaving more free in the body to act on myriad different bodily functions. In my case, it actually caused serious digestion issues. It really clicked for me how everything in your brain is a physical process. Not just motor function, but cognition and emotions are all physical functions of how a very complicated mess of molecules bounce off each other. Autism, Alzheimers, ALS are all just misfiring molecules inside your skull. And it is therefore a given that it is physically possible to realign them back into order somehow. We just need to find the right tool to do it.

Symmetric algorithms are largely safe-ish; the best known attack is Grover's algorithm, which reduces the effective bits by half (runs in O(sqrt(N)) evaluations). Shor's algorithm is a polynomial-time solution to the discrete logarithm problem, which has traditionally been the basis for asymmetric cryptography.

So it's a bit more than a 10X size increase.

But 20 years ago we were using cryptography without it being an undue burden on the network. How much more bandwidth do we have now? How much more storage? Even on phones without wifi available, we're in pretty good shape.

Measuring cryptographic overhead as a percentage of available bandwidth and storage, it'd be interesting to figure how many years we'd regress if we went post-quantum. I'd bet it wouldn't be dramatic.
It was thought of as early as in 1960s by Rosenblatt but he did not come up with a practical implementation at the time. Lotsa things look obvious in hindsight.

2002 SpaceX is more where Boom was a decade ago when they were founded, what have they been doing since? They have one demo aircraft, not to scale of what they are marketing, and have not even demoed an engine yet. What about that makes you think they are the next SpaceX?

Even the comparison is poor. SpaceX had I guess the pieces that what would become ULA as competition? None of the players in the field had innovated for decades because they didn't need to, exactly the sort of area that is good for new people to come in and take a shot at getting a piece of the pie. And on top of that, you have an incredible amount of money and desire for the service. This has no where near the same market.

On top of that the commercial jet / engine world is incredibly competitive. Boeing/airbus and pw/ge/rr/safran have not been sitting idling by for decades reusing the same old designs with the same old technology. If you think that because this is supersonic it's not in competition with them... well I guess that's your choice in how to look at it.
Becayse marathons are relatively short distance.

We observe the same in ultracycling where Lael Wilcox is among the fastest.

The thing is traditionnally sports have been invented by men with charactetistics/rules that suited men first.

You also have to take into account that in any society influcenced by patriarcal and sexism schemes, it is logical that they ate simply more men participating. The base level of a group always increase with the participation and competitivity within that group.

Yeah, but not sure if OpenAI is profitable yet (they lost $500M last year), and costs are rising, and competition increasing.

GPT-4 cost $100M+ to train (Altman), but Dario Amodei has said next-gen models may cost $1B to train, and $10B models are not inconceivable.

I'd guess OpenAI's payroll is probably $0.5B (770 highly paid employees + benefits, not to mention hundreds of contractors creating data sets).

For some reason what really sticks out to me is how when you zoom out, you always come out of a different part of the circuit, so it doesn't feel like the normal repetitive fractal, you're seeing all the parts of the machine from different chronological angles or something.

I don't think that get() needs to launder that pointer. The object of type T is constructed only once in the storage provided by an array of bytes.
The Platonic ideal of the perfect manager is still going to want to know what's going on when a report isn't checking in commits. I vigorously agree that software quality requires that developers be free to take time to analyze, plan, or just think things through, but zero code days can also indicate a blocker or a performance issue, and a manager should be helping with those.
> Mox is nothing more than a kludge to get around the limitations of the language and I think there are much less invasive kludges available. To be honest when I’m working with devs who are new to elixir I’m embarrassed when I have to explain how Mox works.

There are other ways, more similar to Ruby etc (e.g. https://github.com/edgurgel/mimic, or with_mock etc).

And also there is the risk to "over-mock", for sure.

But a good middle ground brings the right value here!

Why shouldn't stuff be allowed to spontaneously come into existence? Why should there be any rules at all to begin with? If there is truly nothing, then there isn't any rule to force the nothing to stay nothing. So the question becomes "how was the universe chosen to be this way, rather than some other way?". The choice must be made, but there is no objective reason to prefer any option over any other. "Nothing exists" is a simple answer, but simplicity is not objectively preferred.

I think the presence of this subjective choice forces a subjective experience into existence with the free will to decide it. Though I haven't a clue how the characteristics of the experience are chosen - that's also a subjective choice. It's subjective choices all the way down.

oh no. you're responsible for a group of skilled and not so skilled engineers in a domain that you don't understand. all is not lost.

what is your only goal - to maximize your teams contribution to the goals of the company. full stop. its not to stack rank your employees unless it serves that greater goal.

but you don't understand the domain. oh no. all you can do is develop a human relationship with the team. listen to them. you can't judge the quality of their work, but they can.

don't ask them to rank each other (I've seen this), but just be attentive. after not to much time you can really start to understand how people are helping the effort, and how they are undermining it. in broad terms, without understanding the gory details.

this is the only thing that works. everything else is just obfuscation.
ASD diagnoses have skyrocketed in the past few decades (years?) with no clear cause. I'm just old enough to remember a childhood without cell phones - we didn't have a computer in my house until middle school but we were lower income than most of my friends - and people are definitely inside more and outside less than they were when I was 8 or 9 years old.

It seems like a plausible theory.
You don't have to look for oxygen etc that are the signs of earth-like lifeforms. I have no idea what prohects like this look for specifically, but any kind of thermodynamic disequilibrium that shows up in the atmospheric makeup of a planet is potentially a sign of life. Free oxygen is a very good candidate, but not necessarily the only one.

So I wonder what resolution would be possible via the 3d version.

What would be really interesting to see with this method would be to make a blend of a spiral-screw with the tesla valves to climb or control vertical rates of flow.

Payrolls gives the labour side of the equation, and captures listed / unlisted / self employeed. Tax receipts probably a pretty decent metric as well. All very much secondary data that would indicate the real number (but its how they calculate gdp etc numbers up in the first place).

Also captures government payrolls, which is probably equivalent in activity in the economy to small businesses. (? cant be bothered to look up where it would rank properly)

This is quite unlikely to be true. No correlation at all?

Especially if we shift to ΔSLOC rather than +SLOC, I don't believe that for a second.

It's true for every other mode of transport but objectively false for planes in flight. However, I'd be curious to see the average when including time sitting on the ground, taxiing, etc., and how that much lower speed affects circulation.
Of course there is always risk. But one of the supposed goals of fiat money and property rights is to reduce that risk, ensuring the ability to save into the future.

There are countless examples of countries where that trust was broken.
That’s of course very easy to remedy by only requiring taxes to be paid by those making over a certain income, say 80k and somehow tied to inflation so the amount raises slightly over time.
A wealth tax sounds good in theory but no one has ever figured out a way to make it with effectively in practice. What do you do with illiquid assets such as patents or equity in private companies? Would owners have to pay for independent valuations every year as part of filing taxes? There's just no way to do it at scale. A wealth tax would also tend to cause people to hide their assets in non-productive things like physical precious metals instead of investing in businesses that grow the national economy.
