Ask HN: Free learning stuff during lockdown which is otherwise payable
Hi folks,

Many leading publishers and vendors are making their training / learning materials free of cose during the COVID-19 lockdown period so that people can sit and learn.

I have found ACM Digital Library[1] and RedHat[2] to be made free for now.

Can you all please point out to some valuable learning stuff which is free now but would be payable once lockdown is lifted?

Gotta make hay while the sun shines brightly on us :)

Yeah, Slack is a chat tool no work organization tool. We use Basecamp for that. Organizing work in an ordered and calm way.
A hammer and a hard place. We have alot to improve -

I had days when i down right thought “this is hell”, when deeply thinking about “modern” life and the exploitation and existential issues needed to maintain it.

I honestly wouldnt choose us, if i was starting a new. on the other hand murder or genocide arent an option either, so we have to improve, somehow, or suffer badly.

Some of us already have no choice.

That is not their mission, stated or otherwise. The repeated emphasis is on health and saving lives.

> CDC works 24/7 to protect America from health, safety and security threats, both foreign and in the U.S. Whether diseases start at home or abroad, are chronic or acute, curable or preventable, human error or deliberate attack, CDC fights disease and supports communities and citizens to do the same.

> CDC increases the health security of our nation. As the nation’s health protection agency, CDC saves lives and protects people from health threats. To accomplish our mission, CDC conducts critical science and provides health information that protects our nation against expensive and dangerous health threats, and responds when these arise.

I think the same people who were inclined to distrust health organizations probably continue to do so, and the folks who were inclined to trust health organizations probably continue to do so as well.

There has been a substantial debate about this (or at least something similar) in psychotherapy since the '70s. It is called the Dodo bird veridct, https://en.wikipedia.org/wiki/Dodo_bird_verdict
In my (brief) experience with PTLDS sufferers, there have been a couple of disturbing realizations/experiences:

1) it seems that "chronic lyme specialists" are physicians who realized that each patient they diagnose with "chronic lyme" is potentially a cash cow. In that they can be persuaded to pay out of pocket for regimens of IV infusions of antibiotics costing up to tens of thousands of dollars (and which make no antimicrobial sense). For years, because the "spirochete is hiding, round bodies, etc etc". The agents used also make no antimicrobial sense - when we show the med history to ID specialists and PharmD's, they just roll their eyes...

2) As a resident, we had a couple of cases roll through the door of a) temporal lobe epilepsy with mesial temporal sclerosis, b) Parkinson's disease, both pretty clear diagnoses, told by various "chronic lyme specialists" that their symptoms were due to Lyme,taken off their meds and put on strange regimens of IV ceftriaxone (at out of pocket expense) and ending up hospitalized as a result. With such severity that efforts were made to have the state board revoke the medical licenses of these practitioners.
Slack just need to fix threads. The UI right now is crazy if you are in more than one thread, I don’t understand why you have to click “x more replies” to see new messages - I don’t think they fixed this in the new update either. Right now it makes me (and others) avoid threads which clutters up channels for everyone.
> i get what they did but they screwed civilians for sure in the name of saving doctors. they actively lied about them being needed so one group would have a better chance.

Think a moment. The sick people need the doctors and nurses alive. Stripping the supply of PPE for medical professionals is lose-lose for everyone. Even if only all of the high-risk non-medical-workers bought effective masks, it would obliterate the supply available to nurses and doctors.

I recently decided to, for the sake of practice, build some single page apps using Vanilla JS. It was such a pain. Maybe some of it is due to my relative lack of front-end JS experience, but I found it nearly impossible to avoid duplicate code. I’m interested to know how people architected apps like that before. I was under the impression that SPAs were not nearly as common before frameworks like React.
> striking the right balance between ease of use and security is really hard.

Why not give more "Options"?

For example when generating conference id, provide an option to generate more random digits or hash codes. When installing provide an option to customize everything. Meanwhile provide a fast and fool-proof path for rest of users.
Reiki focuses specifically on this aspect in emphasizing the focus, intent and emotional commitment of the practitioner. Replace "energy" with "emotion" and it begins to look legitimate.
This new seem to be an April fools joke. There's no mention of the incident in Venezuelan press,nor Reuters nor AP.
There’s a wonderful software magazine in Japan called “Software Design” that is complete with code examples and tutorials on various topics, including web programming (both front-end and backend), Python development, Linux system administration, databases, and much more. It’s issued monthly and has been published since 1990, constantly keeping up to date with the latest technologies. The latest edition features AWS, storage, and containers.

> I would not want to be a manual font designer in the future.

I wouldn't want to be any designer in the future. Eventually there will be a tool to generate any design with easy sliders and stuff. You can already design logos in software that are as good as the best designers 20 years ago for free with a few YouTube videos, imagine what this type of generation tech will do in the future.

I think that along with the current easy to use API 3rd-party systems, like Stripe or Uberauth, we're basically going to go back to a ColdFusion style design tools for the "low hanging fruit" sites like regional grocery stores and below where there are generic templates for a whole e-commerce site and back end for your business with the front end included, but this time you can use all kinds of knobs, levers, and buttons to adjust it to look unique and personal for your business and the backend generation will happen based on your product data requirements and the like.

We already kinda have that for mom + pop stores and smaller businesses. The only companies that will need handcrafted web apps will be the out-of-the-ordinary businesses like Uber, or the huge companies that need more complex logic, like FedEx or Walmart. Everyone else will either do it themselves with whatever the Wix of this type of thing is or they will hire some farm of developers (like an Amazon warehouse, but with developers instead of pickers) to task one of their drones to do it.

On different kind of note, that page header font warping thing is super fun to look at while intoxicated!
> Isn't all psychotherapy in a way just a placebo?

Absolutely not.

It is one thing to just give someone a sugar pill or a random ritual and tell them "this will make you feel better". That's placebo. (Not saying it never works, just that's the definition of placebo.)

It is another thing completely to help people realize which thought patterns and which conscious focus and which memories keep them stuck in old loops. Which subconscious patterns and habits make them miserable. Which parts of their current world model are not working for them and help them actually transform the way they think about themselves, view themselves, feel themselves, the way they operate in the world on a day-to-day basis. That's psychotherapy. It is literally changing the software of the human mind.

Now there might be fake psychotherapists out there who don't know what they are doing and are limited to the effects of placebo in their practices. But that does not mean that one thing is the same as the other.

I can also see how there could be cases where a person receives a placebo, for some reason (the magic behind placebo) it makes them feel exceptionally well, and they use this push of energy to transform some part of their worldview on their own and so they keep some long-term effects of it. This doesn't either make one thing the same as the other, and it does not happen so often either.
All of those that are actually compiled to native code?

Optimizations done at bytecode level aren't worthwhile unless you are targeting pure interpreters.

Still, there are bytecode optimizers for Java and .NET, that is part of what code obfuscators are able to do, what many toolchains for embedded devices do as packing step, and a standard step in Android builds.

In what concerns JIT/AOT themselves, well having bytecodes with a kernel JIT is what has allowed IBM and Unisys to update their hardware designs, while keeping software with several decades of history to keep running.

It is also what allows Android and watchOS code to transition to 64 bits without most developers even having to care about it.

Or how Android, Java and .NET developers are able to take advantage of AVX auto-vectorization, string SIMD, bits operation optimizations, without having to touch their decades old binaries.

It also allows the usage of cloud compilers (UWP, Android, IBM J9), which gather PGO information across multiple deployments and use it as input to the top tier JIT/AOT optimizing compilers.
If you have studied this then you should use your usual identity with its established credibility to state your views. State them honestly and you will be treated honestly, is my experience of HN.

I don't believe in Reiki or stuff like this in general though I do appreciate the placebo effect and think that personal interaction has a benefit which is difficult to measure. If people wish to be spiritual then that may be good for them but that doesn't mean that spirits exist or have any measurable effect on the physical world. However I had a partner some years ago who was Reiki trained and did very much believe in it so as a result I have experienced Reiki and found that the effects were not clearly undetectable. For instance, though my partner did not touch me at all during sessions, I could feel the same things that I was being told. I am specifically referring to the 'energy flow' which 'channels itself to the most needed area' which I could feel the heat of this burning in the same area that my partner told me was problematic which was all around my shoulder and collar bone. Interestingly, about six months later I had a problem with a dislocated clavicle for no apparent reason (just woke up like it) though I had no treatment for this and have had no further issues for 20 years.

Anyway, apparently the person who started ('discovered') the modern Reiki movement found that his power to heal was not valued in general so he formulated the modern system where you must pay a master to be advanced through the levels (I forget but I think there are three levels) and stated that this should be an increasingly significant payment and those who are activated like this should not give Reiki for free. Now, this whole thing sounds so much like a multi-level marketing scam it is unreal but at least my partner was not involved in this aspect, had been given the training and activation for free by a buddhist monk and did not believe in charging for treatments.

It's not completely clear whether there are any psychotherapies that are better than placebos.

Though you have to be careful how you define your placebo.

One approach would be a sugar pill. But the patient would know that this is not psychotherapy. So it doesn't work as a proper placebo.

A slightly better example is a heartwarming chat with a high status individual who is not schooled in any psychotherapy. Say a random professor.

Video Meeting Platform Zoom Addresses Criticisms
A trick I use to make the JS code more maintainable is to wrap code into pure functions that returns an element. For example if you need an input that only accept numbers: var input = makeInputThatOnlyAcceptNumbers() where the function returns the element, and all nitty gritty state handling is done inside the function.
Well for example all of the explanations of how the exercises worked were wrapped around "elements" - you know the usual fire, earth, water etc. And you had "channels" that you had to move energies through by ... rubbing them.

The motions and the rubbing itself did help blood flow and it was quite a nice work out, but I'm quite confident there weren't small spirits of fire flowing down my skin, at least not in the sense the teachings portrayed them I think.

> nearly impossible to avoid duplicate code

Do you think duplicate code bad, no matter the case? I'd like to hear your thoughts.

Personally, I don't mind a bit of duplication and difficult coding if I can avoid a juggernaut like React, but I also don't mind simpler visual UIs. I actually prefer them over the complicated SPA that tries to look and feel like a native application, because it never works. There's this "uncanny valley" between native application UIs and SPA web apps which try.
From your study on point 2: "Results of our systematic review and meta-analysis show that there was no significant difference between N95 respirators and surgical masks when used by health care workers to prevent transmission of acute respiratory infections from patients. However, wide 95% CIs from our meta-analysis must be interpreted as insufficient evidence to determine whether there is a clinically significant difference."

What the study says is that we don't have enough information. As an example, one of the studies referenced in that study gives odds of 0.58 for getting infected with surgical and 0.42 with N95.

Bonus quote: "Furthermore, we do not have an adequate understanding of the number, size and dispersion of the droplets that contain live, infectious particles produced by infected patients.56 A laboratory-based study reported data that humans infected with influenza rarely produce aerosols that contain infectious viral particles.57 In 2 other laboratory studies, participants infected with influenza produced droplets containing viral RNA, but viral RNA could not be detected on manikin headforms or on filters of breathing manikins at distances as close as 0.1 m following participants breathing, counting, coughing or laughing.7"
> “What do you guys do when you just want one cup of coffee?” Adler had wondered this many times himself. He’d grown increasingly frustrated with his coffee maker, which yielded 6-8 cups per brew.

Why can’t you put just enough water and coffee in a standard coffee maker to make only one cup? My coffee maker came with a manual that said, “Always make a full pot”, but I never understood the reasoning behind that. (And admittedly never tried making just one cup to see what happens.)
When you know touching your face is the worst thing you can do this has personally been a proven lie. I assume if there is science behind a study that tracks people through out the day and shows people touch their face more often, that they were not told to avoid touching their face. I think to touch an eye brow or my hair and my face subtly moves and I feel the mask on my face and realize that I should not come anywhere close to my face. People are not stupid, they just need to be educated.

This is BS. You can be aware of existential threats, and respond to them appropriately without feeling the slightest bit anxious or paranoid. It's called planning.

The personal founder experience related here has value, but trying to create this big theory of psychology from it is not helpful, nor are the extraordinarily tenuous links to panic buying and immunology.

edit: This comment reads quite aggressively, which was not my intent. I just want to provide a counterpoint because I don't believe the central thesis is correct, as it runs counter to my experience. Someone might still find it helpful as a model though.

I guess the more you know, the more threats you can perceive, so at some point you just have to turn the limbic system off. The amygdala is not yet compatible with Wikipedia. i.e. there are existential threats that make the COVID-19 crisis seem like a picnic, but if we can't do anything to mitigate them, why worry?

This happens on set top boxes, especially when the graphics memory heap is allocated separately from the system memory heap.

Having two heaps on a low memory device leads to unfortunate compromises.
It's a way for patients to spend time with someone who cares or at the very least pretends to care. And the touching gives it a sense of intimacy. This is like catnip for lonely people.

As such, this is clearly not placebo. But I find it sad that what could be a normal part of everyone's life (taking to people who care about you) is being presented as a medical intervention.

Also, I find the timing of the article odd. Exactly now that hospitals are overwhelmed they propose treatments that require even more staff time.
