Most people at these company are just trying to get through their day and don't care that much. At amazon the only time I heard social media/blogs/HN brought up was if one of the systems that your team directly worked on was in the news or if there is some obviously explosive story going on (like that NY Times article a few years ago about how much of a terrible workplace amazon was with people crying at their desk).
...but not wisely concerned about the security risks of running your own SaaS on your own server, and have enough spare time and energy to meticulously implement proper security procedures, and keep it up to date, safe and secure, 24/7.

He said "Please don't say self-host" for a good reason. Do you really believe that most regular people have the free time and technical skills and security chops to "easily run your own server instance" safely and securely?

If you think that's "easy", then you're doing it wrong.

Linux is only free if your time is worthless. ;)
Having recently relocated from a fairly populated region to a fairly rural area... A few things to add to your list that some people might not think about until they need it:

1)Doctors/pediatricians/dentists etc.

2)Emergency veterinarian (for those late night "what the hell is going on with my dog" moments)

3)More than 3 lousy restaurants

I'm sure there are many more, but these are the ones that were the biggest shock to our family!
I was asking you to justify your statement. You don't get to make such an assertion then hide behind "prediction is hard" when asked to justify it.

I will note that there have been past attempts to call a floor in the cost of PV, for example the period from 2002-2007. That was not the floor.

Current cost breakdowns are nice, but don't show that costs can't be further reduced.

> For example, what is stopping land owners from raising rents for solar projects?

What stops them is the enormous quantity of land that's available. In the US, for example, land can be < 1% of the cost of a utility-scale PV installation.
The hassle of no adblockers (or extensions), bookmarking/read listing/redirecting/etc. from in-app webviews, inability to add a website to Home Screen, zero PWA support (even if Safari's is limited), and I'm sure there's others.

It's not Firefox's fault. It's just that Safari has system-level privileges that Firefox can't have, despite just being Safari under-the-good.

With that said, I'm not the person you replied to and wouldn't argue against someone using Firefox on iOS. The above are just my reasons for not using it, so it's understandable if those things don't matter to others.
On the other hand, Teams is the reason our entire org is now using 16GB ram as the minimum for all new laptops. Getting a developer laptop with 32GB was like pulling teeth before, now it's quickly becoming the standard, all you need to say is "I'm a developer".

So it's not all negative.
Seems as good a time as any to ask about the current purpose and future of AIX, HP-UX, and similar. They seem similar to mainframes now. I feel like they only exist to support legacy systems -- even large enterprises today really seem to want to horizontally scale on Linux.

> So far, the average costs of launching cargo remain on par with the space shuttle at about $US30,000 per lb. (The space shuttle cost about $US1.5 billion per mission, including development, and could carry up to 50,000 lbs of cargo.)

Also not to mention that the Wikipedia table is probably irrelevant, because for the Space Shuttle launch cost is just the total cost of the entire program (including R&D and everything else) divided by how much it actually carried, while SpaceX figures are literally just Elon's marketing material. Look at the citations.

> The development of commercial launch systems has substantially reduced the cost of space launch. NASA’s space shuttle had a cost of about $1.5 billion to launch 27,500 kg to Low Earth Orbit (LEO), $54,500/kg. SpaceX’s Falcon 9 now advertises a cost of $62 million to launch 22,800 kg to LEO, $2,720/kg.

The fact that SpaceX advertises that figure doesn't make it true.
Say you have mirrored devices. Or RAID-5, whatever. Say the devices don't lie about flushing caches. And you fsync(), and then power fails, and on the way back up you find data loss or worse, data corruption. The devices didn't fail. The OS did.

One need not even assume no device failure, since that's the point of RAID: to make up for some not-insignificant device failure rate. We need only assume that not too many devices fail at the same time. A pretty reasonable assumption. One relied upon all over the world, across many data centers.
> I don’t know why decades later after this law came into play, nobody at Mozilla or Chrome teams thought of pushing that as a web standard, it just seems so obvious to me: if it’s something every website has to build it over and over again, let’s make it a standard. This way the browser itself could handle it, and so much better

They did. There was the do-not-track header. Of course nobody used it. Sites don't want to make it so you can automatically opt out of cookies. The only way they'll use some standard system that allows that is if the law forces them to.

I did vaguely hear that that may happen. Presumably the bureaucrats that wrote that bit of the GDPR (apparently without consulting anyone who knew anything about the web) do use the web and they must have noticed how annoying it is.
It's Microsoft. Corporations of that size don't really have to worry about technical details that much - the competition can eat their lunch here and there and they'll still survive. They know they can crush any small fish any time.

I mean, look at this very thread: Slack effectively invented this "modern IRC" bullshit, but still, when MS decided they had to have an answer, they cloned it and effectively imposed it to millions of users, no matter how inferior a product it might have been - in just a few years. They can throw hundreds of millions in the fire and they'll still be okay. No need to rush for a few perf tickets...
‘Zero-Click’ Hacks Are Growing in Popularity, Practically No Way to Stop Them
I never thought about how being diabetic takes emergency preparedness to a new level. We saw people unexpectedly stuck for a couple of days in traffic because of snow recently. What if there is an earthquake and you can't get to somewhere with snacks? There are so many situations that could unexpectedly arise that could cut you off from food. If I'm cut off from food, I'll be fine for a few days. Not so much a diabetic. That's scary.
full reusability is the holy grail. It could have been achieved at the time of X-33 with a little bit of clever engineering.

There is usually 1-2 order of magnitude cost difference between vehicle price and the gas in the tank.
I have found personally only pair programming with people regularly is the only way you can avoid adding lots of technical debt.

Technical debt isn't always avoidable, but I sure know the difference from when teams are heavily invested in pair programming vs not.

Good pair programming is hard to ingrain in a culture though.

Hm, rebooting the pi doesn't change any state on its own.

Lights which are ZigBee or wifi might turn on when power is restored, and most of my automations are of the form "when motion sensor state changes to occupied: turn on light. When motion sensor state is vacant for X minutes, turn off the lights", so they might stay on until you walk by the motion sensor, at which point they fix themselves.

If you have smart switches, I think they would be off after a power outage.

S3 is often essentially a database in these scenarios. You store columnar data format files in S3, and various analytical systems can query with S3 as a massive backing storage.
Snell's law is about refraction rather than reflection.
I think you are slightly distorting both statements when you are constructing that contradiction. If you drill down into Amazons "bias for action", what they really want is that if an issue is urgent and blocking then people should feel empowered to deal with it without having a full knowledge. They should take that risk. That doesnt mean always acting fast without knowing details.

Meanwhile staying curious isn't necessarily about researching decisions in particular. It involves for instance ongoing tech education.

So if you think about it ongoing education is totally compatible with making occasional snap decisions.
On ZFS on Solaris / Illumos you get a choice of whether fsync() acts as a write barrier or actually waits for writes to complete.
I am from the Czech Republic. Our inequality is better than American, for sure, but we seem to be on the same track. Especially the gypsy ghettos are fairly bad. Not as bad as the worst places in the U.S., but shockingly bad for the middle of the EU. In neighboring Slovakia, some of the mud hut villages look like a mixture of the Middle Ages with rural Nepal. So I am not really sure if the better numbers aren't result of some creative statistics.

I still believe that Karikó's equipment was fairly bad, because I was alive in the 1980s and I remember the shortages of everything. Late stage Communism was all about stuff shortage. Either something was really plentiful (but usually of questionable quality), or very hard to acquire. This included school equipment. The first home computers spread some 10 years later than in the West and we regarded them almost as godly objects.
The first citation is irrelevant as it is from 2008.
> Mozilla have limited resources and they (and Firefox users) want the browser to be successful and sustainable,

To begin with, near nobody uses Firefox today. Very succesful, and sustainable.

I have to pour heavy sarcasm here. It's honestly justly needed.

Firefox went from 50%+ to sub 1% under the current leadership.
That's actually really cool, thanks!

Sadly yes.

And you can blame all the fuckers who ran to Slack and VSCode, for it. Once electron became "acceptable in polite society", it was all over.
You ask, "Don't all ray tracers use snell's law or is there a different equation for reflection?" The answer is that, well, you can derive both Snell's law and Heron's law of reflection from Fermat's principle of least time (which you can derive from the wave equation), but Heron's law of specular reflection isn't usually considered to be a consequence of Snell's law; even when you're implementing TIR you can't just use the Snell's-law result because it's gone imaginary.

If you only want diffuse reflection and shadows, which is a thing you could potentially use ray tracing for, you don't even need the specular-reflection law. This might be a sensible thing to do if, for example, you were rendering a 3-D IFS; using a raytracer with BVHs allows you to do this lazily and thus get immensely more detail than a rasterizer could do.

(An alternative to conventional raytracing I've been thinking might be fun is to train a PINN on a scene with the wave equation --- a differentiable neural network which maps (x, y, z) tuples to "electromagnetic field" vectors or just pointwise amplitude and phase, trained using a loss that incorporates its deviation from the wave equation and the given boundary conditions. Then you can evaluate the amplitude of light at every pixel on an imaging plane behind a lens or pinhole camera, thus simulating bokeh, reflection, refraction, defocus, and potentially even diffraction and polarization effects. Then instead of explicitly programming Heron's reflection law, Snell's law, the Fresnel equations, etc., they'd just appear as emergent properties of the wave equation. May not work out in practice tho.)

Perhaps if Cyperpunk 2077 were using a liability pipeline that was rethought with SSDs in mind, you wouldn't have to have all that data in your RAM at once; most of it could be left on the SSD until later, thus avoiding the 30-second delay. (As I suggested, SSDs are maybe two orders of magnitude higher bandwidth, but have nearly four orders of magnitude lower read latency.) This kind of thing is a bigger problem for open-world-type games like Minetest where the data volume is potentially unbounded because players add to it over time, and where the 30-second glitches can't be papered over with cutscenes and the like.

What are some unresolved theories in AI
I made a short list of problems or areas in AI that I struggle to find answers on or simply understand. And I wonder if some of us also have similar issues about AI in general. The field of machine learning is growing so fast to keep track of everything evolving.

1. What is the computational complexity class of problems that humans can solve but artificial intelligence cannot?

2. Can neural nets always solve problems better than social nets (collective of people)?

3. Is there an Ecological Approach to Computer Visual Perception? JJ Gibson proposed a treatise of vision as related with objects around, so is an agent affected by its environment (similar to the concept of phenotropic computing by Jaron Lanier)

4. Does the presence of an agent affect the environment and model in Reinforcement Learning?

4.1 What is the causality of having an agent present in the environment, does its presence affect the reward system. In quantum computing each measurement affects the environment.
Per https://hsivonen.fi/encoding-telemetry/, it looks like they run a special encoding detector on .jp sites, which is presumably designed specifically to choose between the various Japanese encodings (Shift-JIS, EUC-JP, etc).

I think your example of emergency services is a bit hyperbolic. This is a feature that is really not often used, whose omission is not fatal, which often requires several tries to get right, and which is increasingly less useful thanks to gradual changes on the Web. Much more widely-used features like FTP and Flash have been deprecated; people howl and yell every time, but yet things still seem to work.
>but we don't live in that world anymore.

And I'm glad. I'm sick of using software that has 2 trillion toolbars, menus and settings. I want something which sets the defaults to be pretty much what I want and makes the settings all the common things I might need to change. Telemetry driven design lets designers build what the majority like rather than the most vocal bug tracker using power users who want exactly the opposite of the average user.

I used the beta without issue, and never experienced anything related to an `~/sdk` directory (I definitely don't have one created). What are you referring to?
Steam, Amazon, Uber, Google...would all be quite painful. Personally I believe this forms a sort of litmus test for me personally whether I consider a company "too big to not regulate". I can imagine some additional CFPB protections which would be useful for these mega-corps.

It's nothing like doing a chargeback to a local independent coffee-shop who double-charged you and refuses to refund the duplicate charge.
One way to think about the popularity of locked-room mysteries is to think about the popularity of knock-knock jokes, or any other joke with a similarly well-worn setup.

Precisely because it's well-worn territory, the low-hanging fruit has all been picked, and the art is in coming up with a punchline that feels new or original.

"The Mystery of the Yellow Room," published in 1908 and considered one of the best of its time, might seem downright formulaic more than a century later, because so many variations have been published since.

So the challenge for the writer of a locked-room mystery in the 21st century is to work within the boundaries of the premise but still make it feel, to the reader, that the climax is surprising or otherwise novel.
I'm pretty sure ~/sdk is only used if you install Go versions using `go install golang.org/dl/<version>`
The real problem for Starship (IMHO) is Falcon 9. Falcon 9 is now the most reliable launch vehicle ever created. With reuse the may well be $10m per launch or even less by now and likely to continue to drop. F9 can deliver ~22t to LEO and smaller payloads to geosynchronous orbit. The payloads F9 can't deliver are quite small.

What people forget is that payloads are deeply coupled to their launch vehicles. The launch vehicle will dictate the maximum weight and dimensions of the payload. You can't just take a payload designed for one vehicle and put it on another.

The evidence for this is the relatively few Falcon Heavy launches we've had and are planned.

So now SpaceX has all this launch capacity without the matching demand for it. It's a big part of why Starlink exists.

Cheaper and larger payload capacities will ultimately change the industry and create demand but that takes years.

It's likely Starship will launch ISS replacements but is there sufficient demand there for this ambitious launch vehicle? What else will it be used for? That's a bit of an open question.

The second one is from 2016 and shows where my 10% number comes from.
I think there's a difference in methodology here. When those numbers of the shuttle are listed, they're including all the upfront R&D spread across the life-cycle of the program. I believe the Falcon costs disregard all those as a sunk cost and only list the actual "launch" costs
"It is a rare example of a transgenic animal accidentally becoming established in nature"

Is it really that rare to have transgenic organisms escape? I would imagine this will increase as the use/creation of transgenic organisms increase.

Two that came to mind right away are modified grasses for golf courses and africanized bees.
Max Payload to LEO 8,200kg. Max payload of falcon 9 is 22,800kg.

Looks to me like falcon 9 is considerably better value on those numbers even at twice the price.
I'm guessing it is just referring to reliability of rockets in general. Reliability should be improved and being able to fly more rockets by being "fully and rapidly reusable" is the right approach. Planes would not have been able to become as safe as they are if we had to build a new one for each flight.
> It will take the space industry a few years to adapt to the new possibilities, yes.

There are tons of possibilities; James Web 2 with 10x the diameter, a probe to catch up with Oumaumau, real asteroid prospecting. Oh and orbital hotels. Does anyone know of any concrete projects?
The point mlindner is making is that the cost of launch vehicles is in the vehicle, not the propellant. So full rapid reuse, so you can refly the entire vehicle a lot, drives the cost per launch way down.
"The CPU can't possibly get too cold" - Untrue. There are plenty of chips with what overclockers like to call "cold bugs".

Sequential logic (flipflops) has a setup time requirement. This means the combinatorial computation between any two connected pairs of flops (output of flop A to input of flop B) has to do its job fast enough such that the input of B stops toggling some amount of time before the next clock edge arrives at the flipflop. Violate that timing, and B will sometimes sample the wrong value, leading to an error.

Setup time is what most people are thinking about when they use LN2 or other exotic forms of cooling. By cooling things down, you usually improve the performance of combinatorial logic, which provides more setup time margin, allowing you to increase clock speed until setup time margin is small again.

But flops also have hold time requirements - their inputs have to remain stable for some amount of time after the clock edge, not just before. It's here where we can run into problems if the circuit is too cold. Imagine a path with relatively little combinatorial logic, and not much wire delay. If you make that path too fast, it might start violating hold time on the destination flop. Boom, shit doesn't work.
In addition, plasma-pass, qtpass, android password store (https://github.com/android-password-store/Android-Password-S...) are nice as well. Throw in a NFC Yubikey and OpenKeychain on android, then you can lock them with hardware keys. Since pass uses git, syncing can be done to a private repo on your home network or even just a cheap usb stick.
Every release they probably have to test that it still works.

Not that I would ever justify removing something like this - it's clear that for a percentage of the userbase, this is necessary for them to browse. But I can see a product manager trying to cut "fat" if they see that 0.01% of people use it.
One of my favourite passages in the SpaceX book is from Gwen after working with Elon for a couple of weeks.

She worked really hard on a proposal about how they would go about selling the Falcon rocket to potential customers. Elon took one look and said "That's great. I don't want you to write reports and proposals, I want you to do it.".

My god, I would give anything for a boss like that.

There are also laws in the US that prevent certain people from striking. Simply signing a phone contract or registering on a website these days eliminates your constitutional rights, like to trial by jury.
