The building blocks are multi-variable calc and linear algebra. The leap from elementary to advanced math occurs when one transitions from dealing with a single function to dealing with parametric arrays of implicit differentials, which are abbreviated in short-hand notation for brevity. Most people , even in tech/STEM, do not get a good foundation in those topics, so that precludes the possibility of deeper understanding.
Yeah, I was looking at that. At $500 USD, that's a little outside of what I'd want to spend on something like that. I'm still thinking about it though.

Thanks. I was trying to be as diplomatic as possible because I didn't have all of the information on hand to get into a medical debate. It's outside my lane.
Now you have economic value it's time to have other kind of values. And with that amount of money you definitely can.

Hi, I'm the author of the rain effect (not of the website itself though).

You can see the original effect here[1], along with an explanation here[2].

If you like it, you can see a few more effects and experiments on my portfolio here[3], although it's been a couple of years now since I've done anything of the sort (that I can post publicly, that is).

Plants are not a sink for CO2, just a transition point. Any CO2 that is taken up by the plant gets released when it dies and decays.
Trees work like natural airconditioners. Ie trees absorb water and emit cooled water moistuire. Thus trees cool air not only by shade but also by a natural form of evaporative cooling.

Please, don’t act like nuclear fusion is a simple iteration of nuclear fission. It’s a fundamentally different process.

Fusion would provide (much) more energy, use (much) less radioactive inputs, and produce (much) less radioactive outputs. Fusion is significantly safer. In a failure mode the fusion reaction will lose containment and die out like a fire without oxygen. Fission rods will continue to produce heat & radiation in a failure mode, and all failure modes of a fission power plant need to account for this.

I’m actually pro fission, because the risks of fission are lower than the risks of coal, oil, and natural gas. Yes, the article was hyperbolic. However, you’re under-hyping the advancement of fusion. When fusion comes it will be politically palpable globally, cleaner than fission, and it will reduce the cost of energy significantly.
> In most other cases of machine learning there is no "objective" solution and hence no "target function" to approximate.

A crucial step of any AI/ML project is to define this objective solution/target function. For example, a task like "classify photos into cats and dogs" cannot be solved by an ML system: it's too ambiguous and ill-defined. We can define a specific, unambiguous task, which we feel is somehow similar to "classify photos into cats and dogs", but it wouldn't actually be the same task.

For example, "minimise the average L2 loss across these million example inputs" is a specific task, which we can hence use ML approaches to solve. This task has an objective solution: return 100% cat for all the inputs labelled cat, and 100% dog for those labelled dog. Interestingly, a perfect approximation of this target function would probably be considered a poor solution to the original, fuzzy problem (i.e. it will over-fit); although again that would be an ambiguous, ill-defined statement to make.

There are many ML problems which aren't of the 'fit these examples' type, but they still have some explicit or implicit target function; e.g. genetic algorithms have an explicit fitness function to maximise/minimise.

Even attempts to 'avoid' this "blindly optimise" approach (e.g. regularisation, optimistic exploration, intrinsic rewards, etc.) are usually presented as an augmented target function, e.g. "minimise the average L2 loss ... plus the regularisation term XYZ"

Front End Developer on Demand
Imagine your favorite front developer is always there for you. No freelance hunt and missed deadlines.

⏰ Delivery in 3 business days
Perfect for startups
No contract

We know how complicated it is to find a good front-end developer and to continue working with him over time.

We wanted to create a service as simple as Wetransfer where you can upload your design, pay and receive the code a few days later on your email.

Long story short.

When I met Jonathan in an anti-café in Station F (cowarking café), we ended up sympathizing. Soon after, we decided to create a Front team and were joined by Fred and Maxime.

2 years later, there are still four of us and we also work with other freelancers. We decided to create devondemand.co to continue working together on the technology we love the most: React.

The story continues every day and we will be happy to develop your
design (Xd / Sketch or Figma).
Walmart has their own SKUs. A lawnmower at Walmart is an entirely different product than one sold at any other store with the exact same name and company. They will work with the manufacturers to cheapen their products as much as possible.

It's like the tool already was the minimum viable level, then Walmart stepped in.

tl;dr

Whenever someone tells you something, don't listen to their actual words, rather make up a story and apply it to them, respond to that instead.

Aso, if you do listen 'be like Kellyanne Conway' and disregard that as well and suggest something entirely different.

I don't have the strength to go on, but that is, and i don't say this lightly, one of the worst things i have read on an internet.
That's only if you consider line numbers as part of the public API, which would be crazy.
I've been trying to do something similar with a less complex approach using incremental automation scripts and creating an operational meta database, then do some light integrations (a Grafana datasource that can use the ops metabase to use information in templated dashboards)

Is Tesla overvalued?

In the short term, definitely yes. In 2030, Tesla will likely be a trillion dollar market cap company.

In the post linked above I share my 10 year thesis for Tesla.

Let's suppose they are lucky and nobody dies because the prototype of vaccine caused some problem or for an unrelated cause that is wrongly attributed to the prototype of vaccine.

How much time is it necessary to make all the trials to prove that the effective and safe? How much time do they save using humans instead of mice for the preliminary tests?
So not actually SemVer.
How does that relate to Intel though? How do you know that reorganization will solve their problems?

They actually injected triethylborane to act as a match and initiate combustion (TEB auto-ignites at freezing temperatures and burns ridiculously hot).

The plane had a limited number of TEB "shots" and those were needed after each afterburner use, or when restarting the engine in mid-air (as crew needed to do under some conditions), so they had to be carefully managed.
> That would be true if we were looking for life currently alive on mars

I mean, why not?

> Fossils would survive a million-year trip just fine.

Sure, but getting to pick where we take the rocks from helps us maximize the possibility of fossils in the sample. The rovers have found rocks with evidence of water - being able to pick those instead of a random chunk (which might've been blasted from deep bedrock) found in Antarctica has its appeal.

> There has only been one serious attempt to detect current life, the labeled release experiment on the Viking lander. It came back positive.

This seems like a good argument for sample return.
This is even more annoying if you're a person of color. Mostly because a lot of the "PC Culture" zealots are middle class white people who are virtue signaling and using these far left ideologies to gain social acceptance - They're literally shooting fish in a barrel when they decide what to say vs. what they can say AND get 'credit' for.

Speaking your opinion and being called a racist on Twitter by white people is beyond infuriating when you're a black man who has actually experienced it. Twitter is a cancer to society, and I really hope this "cancel culture" dies out soon.

Most times when things like this happen, someone could have easily sent the person in question a DM, explained why they thought the tweet might have been badly timed, and that would have been all - No scandal.

But you don't get "credit" for that. You have to pretend to be angry, make a tweet with some ALL CAPS thrown in, and get someone fired. I hope people find another way to feel good about themselves soon, because throwing people under the bus is destroying any hope of free speech in the near future. Sorry about the long rant.

Hopefully I don't catch any heat for this on HN shrug

Boiling more water than you need at that time is a waste of energy.
Above a certain price point you probably want an ad hoc sales process. $1000 flat rate sounds like an awkward price point. Expensive enough to not get any random sales, but might be too cheap to build a big B2B business around it. Especially if the market is small. You want to extract as much as possible from people who can pay.

At this price you'll be doing calls either way. Why give the price away?
You're absolutely right, and I think most of us have a hard time a. learning about all of the new features and b. justifying going back and fixing up stuff to adopt the new features, but IMO for such a critical piece of infrastructure it should have been done and the engineers/architects should have been adding that sort of stuff to the backlog or requesting training or asking for resources, etc. For me, that sort of stuff is the only way I can get the green light to go back and refactor.
Isolating is not necessarily more healthy, nor required everywhere right now.

For example in Norway, you don't have to isolate. The numbers are relatively low, the clusters are well tracked, the few travelers from dangerous countries like USA have quarantines. You still have to be careful of course.
> If you are a small team solving a small part of a larger problem and you have done a good job of defining your external interfaces

I think that's where you and the other commentator are talking past each other. Amazon tends to have great managers and senior ICs that get the responsibility and technical divide right.

My experiences outside Amazon unfortunately point towards this being hard to get right in the first instance, and really really hard to fix once it has gone wrong.
The drops flicker in OSX Chrome 84 for me. Works in other browsers.

Not surprising though. This 2017 Macbook Pro's integrated gfx (Intel Iris Plus Graphics 640 1536 MB) seems incapable of rendering any 3D games after 2010 without flickering at some point. It's one reason I'm still playing Morrowind (2002).
My experience with this has been that when teams dissolve, new apis are created on top of the existing apis to avoid making changes to the original api. Debugging a production issue now involves a lot of finger pointing about which API is working correctly, and which one needs "the fix".

>But by the sentiment of all media reports INTC is in sharp decline & AMD is killing it, yet even in their most recent results Intel revenue/earnings still dwarfs AMD's.

Decline means decreasing. Which is true. But they are decreasing from a big number.
I think most of the power envelope difference these days is process node, with Intel chips usually lagging behind.

That being said, I do think that if the same amount of performance engineering were dumped into ARM as has been put into X64 ARM would win. The simpler instruction encoding, less cruft (but not none!), and other modern characteristics would make that optimization go further.

My concern as others have mentioned is lack of standardized interfaces and peripheral enumeration, leading to a lack of flexibility and the loss of ability to run alternative OSes and drivers. That can be fixed, but does anyone care enough to fix it?
There’s no way they could generate similar revenue per user. Revenue per user depends on much advertisers are willing to pay and there are a couple of differences:
1) Targeting: Instagram has exceptional ad targeting because it utilizes facebook’s existing data which TikTok tool doesn’t have.

2) Online spending: In theory wealthier countries / demographics should have higher online spending. May also have correlations with gender, age, employment status, number of digital devices, delivery infrastructure, etc.

3) Advertiser relationships: the real customers have to want to put their stuff next to your content.

4) Political risk: if many countries ban it, it’ll lose access to a lot of high value markets.

Lastly, profitability doesn’t always come later particularly for high bandwidth applications. Personally I’ve been getting a higher number of ads from YouTube but they are exceptionally poorly targeted (I skip at-least 90%). I would expect google to have as much data as anyone. The only explanation I have is that it’s simply too expensive to produce video ads to have an efficient targeted ad market.
This is a good point. The major negative impact of Amazon is on labor rights. I had a sobering conversation with a canvasser who came to my door last week; they were gathering signatures for a local bill, but their other job was at the Amazon warehouse, and they suggested that walking in the hot sun and talking to hostile folks in their home was far easier than running up and down the halls of Fulfillment.

It's a common sentiment that Sherman Antitrust was a prerequisite for prosecuting and breaking up trusts a century ago; we needed powerful legislative tools in order to even define and understand the abuses that those corporations brought upon us. Similarly, I have heard many people suggest that we will need new legislation in order to properly describe what Amazon has built in terms of systems which deliberately abuse labor, control shoppers, and grift the public.
In the US these are called 'slice pies' which are enormous and not meant (usually) to be ordered whole.
Help me understand why this is so controversial in the scientific community. I'm neither a physicist nor do I study any other relevant fields, so I'm asking as a "layman" as it were.

A cursory search shows that "dark matter" hasn't been observed at any point in time. It looks like it's a sort-of mathematical placeholder for the "something" that's missing that we can't see (or can't see _yet_.) Am I correct in my understanding that these alternative theories are trying to prove that there's a way to explain these discrepancies without inventing something unobserved?

Why is that so controversial? To me, again as an outside observer, it feels so counter-intuitive to _invent_ a new type of matter you can't observe than to just say that your calculation is close but not right and to start over. Is it not a crutch?

If I were to take this approach into another field that has an equal amount of controversy where there is a huge gap in my proof, and say that the cause is an "unseen force" that I just invented to explain how my theory works despite the fact that I can't prove in any way that the key part of my theory exists, would I not be laughed out of a room? How did dark matter become accepted while being invented instead of observed?

(I hope my tone isn't coming off as mocking. I'm genuinely trying to understand without a lot of knowledge on the subject, and I don't intend to discredit the current accepted theory nor support the alternative ones, only to understand why the scientific community came to accept the one that is accepted.)
All of that is only true if you only look at the successes, such as those you’ve illustrated.

I don't get that logic. So what if they have liabilities?

They also had experiance, proprietary knowledge, tested supply chains, tooling etc. etc.

I think the problem is that everyone is buying into the Musk==SpaceX story, which I think is wrong. He is a marketing gimmick that secures funding and cheap labor (through hype) and maybe some clients.

If you ask me, from what I've seen the actual person responsible for SpaceX is it's president/COO: Gwynne Shotwell.

Show HN: VoltBuilder, a Modern Replacement for PhoneGap
Hey HN, I’m George and I co-developed VoltBuilder (https://volt.build) with James and Tomo. VoltBuilder is a modern replacement for PhoneGap.

Early in the COVID crisis, I was running out of work and looking for a new project. I saw Adobe was abandoning PhoneGap, a tool used by thousands to convert web apps to Android and iOS native apps. (I’ve been a PhoneGap user for 10 years, so I knew I’d miss it)

I spent a weekend going through the Android, iOS and Cordova documentation to see if it would be possible to replicate what PhoneGap does and give myself and all those users some hope. Reading hundreds of messages on StackOverflow helped me figure out some stuff that is really, seriously not documented anywhere.

By Monday, I had something like a POC working. I checked with my long term collaborators, James and Tomo. They were similarly underworked, so we decided to go ahead with the other 98% of the job to make a working product.

Technologies used include Python, Node, Jekyll, Auth0, Stripe, Cordova, Xcode, Android SDK, Express, Helmet, JWT, Flask, Boto3 and more.

VoltBuilder now has a website, a build engine, queuing and billing. We’ve built the server infrastructure to spin up multiple builds at the same time and are starting to test that.

It’s deployed in beta production. About 50 beta testers have thrown thousands of jobs at it. We’re focusing on building a community to get our first users and gather as much feedback as possible. Pricing is still up in the air, but the pricing page shows where we are heading.

Thank you for reading this far. I would love to get your feedback on VoltBuilder and to answer questions.
So your argument is that because it works for your disease, it must work for covid. You provide zero evidence that it works at all for covid, zero evidence to counter the studies that show it doesn't. Then you claim some conspiracy that hcq is not being used because trump touted it. And this is supposed to be evidence of what, that society keeps you from sharing your stupid, idiotic opinions that have no basis in reality and can easily be disproved? If that's the case, good. Society is doing its job. You spoke stupidity and were shunned and unwelcomed. That's exactly how free speech is supposed to work when you say something this stupid.
If skipping patch numbers I don't think this is actually SemVer. Rather it's a custom versioning whose major and minor convention is similar. (Which is fine just not SemVer.)
Whether or not they are free to punch you has no basis in whether or not your speech is protected in that instance. And sometimes they are free to punch you.

If you say you're going to kill me (not protected speech), and a reasonable person would believe you, I can hit you in self defense (affirmative defense for criminal battery).
The cool thing is that cheat detection/unfairness detection seems to happen at the semantic level of reasoning. You can see this with kids - one example I recall is a friend's 5 year old being upset at seeing another kid with ice cream. $Parent said it was that kid's birthday (who knows), and her kid immediately got over it.

So if only billionaires were human, we could just suggest their semantic categories were wrong. <rimshot>
Nope, I don't believe so. In the long term we're all dead, and students need to be learning and staying motivated every day.

Remember, phonics gives immediate improvements too, for short words. So it's pretty much a false dichotomy.

For students who are picking up phonics quickly from the start, great. For the students who are struggling from the start, try other methods ASAP.

As a teacher, figuring out which methods work for a student isn't rocket science. Your students are either getting better on a visible daily basis or not. We're not talking a 5% difference in outcomes, it's more like 75% difference. (Of course, bad teachers just don't pay attention at all, or are too swamped with work to be able to.)
Yes, that's the "and investment" part of what I said.
These companies did "release open data". It's called Cambridge Analytica. Look it up.
That's an incredibly disingenuous response. I am sure you are perfectly capable of understanding what I said and how true it is.
Many tactical aircraft to this day use their fuel for the same purposes. I know the F-35 uses its fuel as a heat sink. The F-35B variant specifically uses fuel as the hydraulic working fluid (aka "fueldraulics")for much of the work of the 3 bearing swivel nozzle.
Spanish also has "ordenador", which is the most common way to refer to a computer in Spain (I think in Hispanic America, "computador"/"computadora" is used more often but in Spain it feels like something old).
Those were solar powered. RTGs are not as plentiful as solar panels. Sending an RTG on rover B means some other space mission doesn't happen because they cannot get an RTG.
