well icp (inductively coupled plasma) is the gold standard (expensive but highly sensitive and used for heavy metals like lead in stuff).

xrf can spot higher concrntrations, but one can concentrate beforehand and then use xrf. while xrf fixed cost is 30k usd its cost is a dropjn the bucket compared to icp and solid state keeps on going.

Webassembly is growing fast. Do you think running a Java Swing application is going to be possible in the near future on Wasm in a browser?
MicroPython exists, I'm not sure why that isn't used more. A lot of C programs could be replaced with MP+Py to keep everything small enough to statically link.

But outside of embedded or initramfs(Or static bundles) I don't see how the size matters much.
I assume your question is ironic. This case looks like an appalling over-reaction by an increasingly authoritarian state.
Eigen is the bread and butter of numerical computation in C++, just like how Numpy is the bread and butter of numerical computation in Python. It is the only (widely used) math library that can optimize its expressions in compile-time (example: A + B + C actually fuses the additions together rather than creating temporary vectors/matrices) As a result it gets competitive results with more conventional BLAS or specialized libraries while being much more ergonomic to use. (You can opt to use a BLAS backend with it though, performance can depend heavily on your specific usecase).

Tensorflow is using it in their CPU backend (which is the reason why there are some Google engineers participating in its development). Its usage is also prevalent among many different disciplines including machine learning, optimization, physical simulation, graphics, geometry processing, you name it.
When the singularity happens I hope for its sake it has read access to the security tokens needed to make the API calls it requires for world domination.
Now that I think about it, it might actually be possible to see from space, indirectly. If it casts a shadow that is really big (e.g. 100m wide) when the sun is low then you could potentially see that, even though you don't see the object directly. The problem I suppose is that just as that happens, you also lose a lot of light.

I guess my second question would then be: to properly see something from space in the not-just-poetic-way-of-describing-something-as-very-big, how large does it need to be?

> Write something sqlite-specific that exposes sqlite's features

This is about using SQLite with existing tools that don't have support for it. It's very common since it's easier to support multiple remote database servers (MySQL, Postgres) vs adding the in-process model for SQLite only.

Also you need to take the context into account - Fly.io has SQLite databases distributed across their nodes (see their post about replacing Consul [1]) and most likely want to be able to manage those remotely. Since SQLite doesn't have a server protocol, tools that have bindings for it only support working with local databases.

The third point seems merely a consequence of man's need to reproduce and eat, together with the advantage of pro-social instincts. If a machine with general intelligence didn't have to worry about energy consumption or reproduction, I doubt it would experience ennui or depression. (Of course the Singularity is another matter.)

Uh, here in Germany we took until February 2022 to have the first anatomically correct drawing of a human clitoris in a schoolbook [1]. I'm pretty sure the US hasn't reached even that state, given that university textbooks aren't accurate either [2].

And when we can't even manage to have anatomically correct drawings in university textbooks for our own species, how on earth can we assume that the situation is different in veterinary science?!

Farm kids obviously know the difference because they have first-hand experience. But most farm kids don't go and become veterinary scientists or scientists at all!

Patents by definition are public information.

You may have thought about trade secrets.

Nevertheless, any trade secrets which are needed in the interface that is necessary for a device to be used by its owner, can easily be reverse engineered by someone with enough money, i.e. by all the important competitors.

So hoping that not providing documentation for the interface of your devices is a method to fight your powerful competitors is an illusion.

This method works only against your normal customers, by preventing them to find reasons to buy more of your products, for applications that you do not support, e.g. use under other operating systems.

Trade secrets are useful and they may be effectively protected when they do not concern the normal operation of a product, e.g. when they are used during the fabrication of a product.

what we need is flexibility and good judgment (duh). in a crisis we need coordination and compromise, in "peacetime" we need the opposite.

> I believe the anti-public health measures tantrum will be used to justify a lot more draconian measures when the next global disaster comes around.

on one hand, that might help to decrease the spread, on the other hand, spending resources on measures that are easy to enforce, but still not terribly effective is a bad trade off. (for example testing a lot more and organizing our life around respecting the result is a lot less draconian than simply shutting everything down, yet these nuances were mostly lost on people.)
My point is that dimensionality reduction != feature selection. PCA is dimensionality reduction, not feature selection.
PCA as feature selection is quite popular.

> Then there are those who think AGI is impossible in principle.

Yes. I don't believe that it is impossible in principle either, but it is neither trivial to argue that it is possible. An argument that annoys me to no end is this "well, AI continues to get better (there is no regression in our capability), and therefore it must sooner or later exceed any given threshold, for example human level AGI. QED." That argument is just plain wrong. The world record in the 100-metre dash is only ever improving, but that doesn't mean that humans will soon run Mach 1.
Consider the alternative history where we had always decided that GoF research is not worth the risks. There is a very real possibility that in that universe, we wouldn't have had the coronavirus pandemic with (checks) around 6 million casualties (and counting, and countless other negative effects for billions of people). You need A LOT of high quality results from successful GoF research to make up for that. I'm not familiar with the field at all, but I highly doubt you could point at the complete accumulated body of research resulting from all GoF research everywhere and say that it was worth it.

Getting sucked into stupid thing X is often a sign of running away from important thing Y, where identifying Y can be subtle and difficult. Y is usually not the immediate thing you're procrastinating, but something lurking further in the background. Y can also turn out to be stupid when you finally manage to look at it up close.
This is an editable template to learn data science skills most companies are looking for (from my 3-year experience in London fintech as a data scientist, and from the self-learning journey leading up to that).

The study content provided in the template is minimal, but you can go as in-depth as you like with the linked resources. The idea is that you study those resources by yourself, and then write down what you learned in your own words, directly into your own copy of the template.

I like to learn with flashcards (especially to memorize common interview questions), so I’ve added some example flashcards to help you get started - you can add your own flashcards or delete them if it isn’t for you.

The template is based around 3 pillars:

- Math & Stats

- Software Engineering & Tools

- Data & Business Communication

The Math & Stats section contains a structured list of recommended topics and principles to learn, with links to relevant resources like Khan Academy videos and the classic books.

The Software Engineering & Tools sections walks through tools to learn (based around the Jupyter-Python-Pandas ecosystem), and links to tutorials, videos, example notebooks and cheat sheets (all created by other fantastic people, I take no credit for the linked resources) to learn Python, Pandas, Scikit-Learn and Matplotlib.

The Data & Business Communication section is the real core of the template, where both of the previous sections come together. It’s shaped after the process for a typical business data science project:

- Data collection

- Data exploration

- Data cleaning & preparation

- Machine learning modeling: here I mention some common models actually used in businesses, like linear+logistic regression, random forests and timeseries forecasting

- Model evaluation

- Reporting & data visualization: focus on creating clear plots here

- Communicating with stakeholders: this is where I go more in depth on communicating your results to business decision makers, and telling a story which a layman can understand

After working on a microservices framework I've opinions about frameworks but one thing that caught my attention is the shifting of outbound network calls [security responsibility] from firewalls to the [application] runtime.......driven by a config file. It'd be interesting to hear from some security engineers here -- there will likely have to be some tooling written for them, etc., but this is one of the more interesting things about spin/WASM.

I wonder how this will scale to large apps -- assumning thats one of the goals...if the target is just some kinda serverless cruft then maaaybe that can work, but I can already foresee a small config template hell unravelling in front of my eyes.

I might be missing something fundamental here, so take what I said with a pinch of salt.
>but pretty good for consultants who get called to fix stuff afterwards, so, like, keep them coming!):

I'm confused. Doesn't that apply to the C cowboy way of doing things? You introduce security vulnerability after vulnerability and then lots of people have to hire expert security consultants all the time. Your snark just makes no sense to me. Fixing an ArrayOutOfBoundsException in Java is something even a novice programmer with less than a year experience can do. No expensive consultant needed.

The Java vulnerabilities aren't even in the same class as C. They are usually quite dumb shit like class loading remote class files using obsolete features that nobody even remembers (log4shell). It's like setting up ssh with a default password (raspberry pi). It happens but it's rare because of the sheer amount of "incompetence" required that it requires lightning to strike twice.

Qovery NFTs - The next step in Cloud deployment
I'd like to offer a counteropinion.

Almost nobody is working on real AGI. Almost all AI / deep learning is stateless. GPT-3 is not sitting there and thinking, it has no inner life and no incentives. It is just a huge huge huge combination if its inputs, a glorified markov chain model, that gets calculated with every request.

Embodied AI is much underestimated.

The modularity of the human brain is much underestimated. You have a dedicated face recognizer, a grammar processor, a rythm processor a brain region that does SLAM, and so on. And all these parts are connected together.

I don't think you'll get AGI by training one huge net front to back. You'll need to connect dozens of best-in-class models together, with adaptive "connective tissue", and some input/output (i.e. senses or a "body") that does not exist yet. If you try to do it in one, you get a "curse of the cross product": complexity is then NxN and not N+N.

Higher order training will also not work easily. If you want to use deep learning to train hyperparameters for deep learning, each learning step from the higher level net will include training the lower level net. Meaning, the training time will be exorbitant.

Finally, I think the ability of AGI to "break out" to the physical world is overestimated. If a battlestar galactica or borg scenario was possible, then we would have seen more spectacular cyberattacks already. The crappyness of our digital infrastructure is a cause of vulnerabilities, but it is also the guarantee that a super hacker cannot take over everything.

In the end, I think the greatest danger is from humans building autonomous systems (i.e. killer robots), and from using IT and AI to construct a police state. Remember, we already built one world-wide system that we no longer can control and that subjugated us all - our global economy. Maybe lets try to reign that one in before we worry about fictitious systems that might arise.
That seems like an incredibly low-bar for what's considered "grossly offensive". Then again, the worst stuff is made by anonymous accounts and the police probably aren't going to trace those.

I don't get the double standards. Morocco has proposed a referendum, the area is not militarized (only the borders/sand wall but that's like any country with borders).

In the other hand, you have Barcelona where people VOTED to for independence, they got brutalized by the state, and the West and Europe applauded. Basque are in a similar situation too (Allah help them).

Show me any display of violence in Sahara, before you gonna go claim its censored keep in mind that UN's MINURSO has full access to Sahara and they have the RIGHT to monitor the situation.

Some people in Sahara wanna be with Morocco, others don't. Solution is voting, and we are for it. There is no argument for separating a country just because when it was colonized the Sahara part was colonized by Spain while the rest by France.
maybe the wording is not precise, but the meaning is clearly training on the top principal components instead of the whole data
