> part of the purpose of the labs is to teach lab techniques. But the cost seems really high to me.

That cost is potentially about to change, with AR/VR-based virtual labs.

Sword combat is something that requires a lifetime of dedicated hard training, with associated injuries... or is something grandma can pick up in a few minutes and do to music. With simulation, realism can be throttled to meet user and class objectives and constraints. Exposure to real-world Murphy messiness is of course still a learning objective. But fighting it need not be quite so pervasive and costly a tax on knowledge acquisition. Especially where "the biggest payoff is having seen it/done it once" is sufficient to need. Also, challenges like getting "incorrect" results, experiment debugging, record keeping, and ethics, can be more systematically taught.

And with lab tech becoming increasingly automated...
Electronically controlled throttles have been on the road for over 30 years now, and became extremely common in the mid 2000s.
Linear regression doesn't require much, honestly, just non-null numeric data. My point was more on the interpretations of the outputs.
I've never had a problem touch typing while my pinky is holding down the shift key. I type kinda weird though. I don't use the right shift key at all. Only the left one.
You can if you don't want to see your keys.

To be honest, I've never tried--I always assumed that I'd want to be able to see the keys in order to place my hands before I touch-type. Maybe I'll give it a go.
Just read the FBI OIG report. Then read the Nunes report. Then read the Schiff report. It's pretty clear who was spreading lies.
Performing this study on humans seems like it would be incredibly easy. Why even bother with mice?
Sure if you have such a friend they would be a great alternative to legal retail. But many people don't have such a connection so the retail option is just a hell of a lot easier than what they were used to.
Affluent pedophile cult conspiracy theories have been a staple of fringe right-wing elements, and the militia movement for some time. Especially recently they've been associated with the populist wing of the Republican Party (pizzagate, Alex Jones).

Given those associations, and the surreal nature of the claims, it's hard not to blame a lot of liberal-leaning people for reflexively dismissing them.

But Epstein's recent death, and the facts surrounding his case seem to indicate that many of those theories once readily dismissed as the product of fevered minds may actualy need to be reevaluated, even if they only contain a kernel of the truth individually.
I got a 4-year cert from K Software for $234 (which is < $5 month). Of course, I had to pay for 4 years up-front, but TBH I'd much prefer that, as the verification process is a series of time-consuming farcical hoops to jump through.

Excuse me. I would say I am now now more aware of HTTPS works however what it is, how it is, how it's a life support of the internet that's going to crash and burn, I did know.

If it's the only thing of the internet to ensure security of HTTP then internet is dead.

For the last time, I do not want to use LetsEncrypt if I am to use SSL. As posted in my previous comment.

To be honest, I bored to continue in this discussion. I've said what I wanted to say long ago, take it as you wish. End of from me.

>That's how most of the world's population will experience your site.

Unless you're FAANG you probably don't care about most of the world's population, but the tiny slice that is most likely to see your site and generate revenue for you.

It's not baffling that most developers don't make things for most people. That's just a waste of time and money.
Another commercial alternative is M-Strean - non proprietary TCP based parallel streaming.

Limited to work with CIFS / SMB / NFS and S3 compatible / OpenStack Swift compatible / Ceph / Azure storage.

Commercial model is server based with no additional bandwidth charges .

Not sure if it is working with QUIC or not as it is mentioned in blog posts.

Are you tired of writing RecyclerView Adapters?
Yeah, The big problem with these frameworks is that, by their very nature, they punish you severally if you ever step outside of the framework. This can cause a whole bunch of headaches if you decide you want to pull in new functionality perhaps not supported by the framework.

An example of that is when you want to mix things like Jquery or React elements in with Angular. It is (or at least was) far to easy to step outside of what react expects you to do. The end result is a break on minor updates. So, instead, you'll often end up with these janky half maintained library like "Jquery-ui-datepicker-angular" (made up) Or whatever that try to bridge the gap as best they can.
AirPlay uses a fixed latency of 2 seconds, so 500ms is not bad. Either way it's not a technical accomplishment/failure, the longer the latency the longer you can put up with your WiFi breaking without having your audio blip.

500ms should be enough that you can roam between multiple APs without the audio stream being interrupted. If you're on hard-wired ethernet you should just be able to modify the snapcast source code to reduce it to whatever you want (10ms should be fine).
Wow, that's everything I like about snapchat without everything I dislike.

Gonna have to try to convince some friends to hop on it.
You can totally feel any delay above 5-10ms so that rules out quite a lot of things. I hear people still do it in some fashion.
Any comparative study with a decent methodology would detect the problem of differing sensitivities per person (by checking the standard deviation among other things).

The problem, as another comment points out, is that this study was done on mice. To me it removes all possibility of applying its conclusions to humans, because our sleeping habits don't seem similar at all.
Ask HN: Should I raise, stay bootstrapped or quit?
Hi HNers,

I am Anthony, solo French founder of LiNote. We build a device so obvious to use really old people ( 75 to 100 ) can use it even with cognitive diseases. Their caregivers can video call them, send them reminders, pictures, etc.

I've been working on it for 5 years now. Our MRR is now over 12kE. We were at 4kE a year ago. Our 350 customers love it and talk about us a lot. Yet we are growing slowly at 5-8% a month.

Our team is 4 people only:
1 dev
1 content marketing
my girlfriend at operations and simple customer supports
me at tech support and "CEO stuffs".

My girlfriend and I love what we do but we provide support 7 day a week, 24H a day.
We have worked every day for the last 18 months.

We are about to get cash positive. We haven't raised money but from family. I am now able to pay my girlfriend and I enough to live decently but far from what I use to earn as a python dev.

We aren't at product market fit yet but our retention is great and we think we are on something but our dev is busy with bug fixes and tiny improvements.

I am getting worse at selling my vision the more operational tasks I do and the more time I struggle with the company. 1000 of customers seems far when you fight for 20 each months.

I've talked with local investors but that didn't work 3 times. I wasn't really committed and feel disconnected to their way of thinking ( hire blindly, build partnerships with big companies). Local investors doesn't seems knowledgeable.

I can't decide between staying bootstrapped which fit us better but the road seems so long before being able to live comfortably and before being able to hire new critical people.

Raising money is a good option to grow faster but not being at product-market fit seems like a non-optimal time to raise.
I sometimes feel like I am being stubborn and if anything big should have happen, it would have already happened before.

I am sure the HN crowd would have insightful comments.

The concentration camps of North Korea can be seen on Google Maps. Surely, the US government is aware of them as well, given the high quality of their satellites [1]. Hence, I'd assume if these "internment camps" are viewable from outside, then the US government knows about them as well.

Why is that disturbing? For me, the name doesn't resolve (http://pn/).

Assuming you are using your parents' ISP's default DNS servers, isn't it a safe, though less-than-desirable, result for the ISP to forward you to a search page when resolution fails?

> Social media and blog posts should be passive entertainment

You sir hit the nail on the head! I analyzed over all (almost all) my bookmarks, lists, notes, posts and emails from 2018 and 6 months of 2019 only to realize this - its entertainment.

I could find 7 distinct valuable things from hours of consuming text/videos for over 18 months. That was insane and in stark contrast to why I picked up reading blogs/tweets/HN in the first place - 1. to dig deeper in what I know and 2. seek new shiny things. I now use books for the former and HN/twitter/reddit/blogs for the latter.

Whats interesting, important and valuable finds its way to my feeds/searches/conversations and has the characteristic of showing up multiple times. The signal/noise ratio is Goddamn low.

I now have sticky notes on the wall right above my desk, one per area of interest. I look for books around what interests me, have real conversations with real people, explain or try to get folks around me hooked onto something that also interests me.

Overall I like it and my favorite part : are only so many stick notes that will fit on the wall. When there are too many, I will know, unlike my twitter/HN/reddit feeds.

I remember reading somewhere about placebo effects changing over time, but I thought that was across populations over time, not for an effect on an individual over time. Do you have more info on what you mean?
I just used (and still use) org-mode to track todos & projects, as well as keep time that was spent on each task.

I tried not to over complicate my task keeping, because I've always been more worried about getting the tasks done, than trying to track progress.

Anything that was in planning/needs more info state got a WAIT instead of TODO, with a note on what was needed. And I'd review my list every morning before deciding on what I needed to work on, or if I needed to start pushing for information on other tasks.

I still do all this btw, I'm just not solo anymore.
There are people literally calling themselves "dark enlightenment" doing this.
Boeing’s own testing assumed pilots respond to runaway trim situation within 4 seconds [0]. Beyond that, the MCAS will have put the plane in an aerodynamic position where the pilot forces required to manually stabilise are too great. 4 seconds is not a lot of time. The Ethiopian pilots were aware of the need to disengage the powered trim and use manual control. They just couldn’t force the controls enough given the position the plane was in. The 737MAX is a death trap. It won’t fly again without significant redesign.

Could also be confirmation bias.
When that happens, I'd surmise that the following is not going to be a good hedge: a completely ephemeral "asset" that is not backed by any conventional power structure or society, while at the same time being fully dependent on a highly sophisticated infrastructure made possible by said power structures and societies.

Cryptocurrencies depend on a redundant and highly interconnected network of many diverse actors to be able to maintain their trust guarantees. How that network is going to stay around in a doomsday scenario is very much up in the air.

The main point, the crucial point of a doomsday hedge is that it should depend as little as possible on the intricacies of the old world.
Fancy tools are for teams, because everyone editing todo.txt eventually gets messy. It is not like you can't use the fancy tools, but if you expect them to somehow improve your work flow, prepare to be disappointed.

The thing about working solo is that you can get away with a lot less communication and writing stuff down. Depending on your memory you probably still should put a few core ideas on paper/file. As long as you are prepared to delete as necessary, putting ideas in code right away might work.

> Convergence takes infinite time when the sampling variable has infinite variance

That a rather assertive statement. I dare say most distributions are (due to CLT) Gaussian.
As I recall, the 707-727-737 are a direct evolutionary line serving the same niche, and the 757 was intended as a 'stretch 727', so yeah, I think you're right.

Similarly, when I consulted with one of the major airlines (although not in flight operations) I was told that many of the physical specifications of airplanes were driven/limited by airport gates. That is, wingspans, fuselage curvature, door height, etc. need to be within certain ranges so that it could use existing gates unmodified. This was one of the biggest issues with adoption of the Airbus A380...airports had to build new gates just to support them. I understand that is an issue with the 737-MAX: to place the much larger engines in a place that wouldn't screw up the balance (e.g. under the wings instead of out in front of them) would make the plane inconveniently high off the ground.

For my first 15 years of using UNIX on PC keyboards, I had to use xmodmap to remap the ~` key back to the correction location the right side of the keyboard... and move ESC to the key labeled ~`. Similarly with swapping Control/CapsLock. I finally gave it up nearly 15 years ago in an attempt to simplify my setup on new systems.

I write down all my ideas in a Trello board, and make sure that they're either easily actionable (can be done in a couple of days at worst) or tag them to split them up later.

My columns are Todo, In progress, Done and Backlog. Anything that's not a priority right now goes to the backlog. Every once in a while my Todo column gets empty, so I make a release and take stuff from my backlog.

Any time I have an idea, I instantly write it down and stop thinking about it. This lets me focus on my task at hand.
OK, privacy nut here :)

I go to great lengths to avoid being associated with the IP address assigned by my ISP.

But I'd never request that it be removed from the dataset. It would obviously be stupid to do it as Mirimir (for example). But less obviously, it would also be stupid to do it as my meatspace identity. Because that would flag it as a privacy nut. Which I'm very careful to avoid doing.

So I wonder what people think that it's smart to have their IP addresses delisted.
I guess I misunderstoof the GP then - which is why I asked why it was relevant (and got downvoted for it...).

I spent considerable time looking into how this could be done well. There are numerous factors that could all be fed into an algorithm to calculate the "pleasantness" for each segment of the pedestrian network. I had focused on factors such as the distance between the traffic and the sidewalk, the speed and quantity of the traffic, and the barriers between. (curbs, trees, parked cars, etc.). Also intersections, trees, street lights, surfaces, etc. This article mentions the use of noise which is something I had not considered.
This may be a problem of what's idiomatic in each language, as opposed to a matter of language design per se.

It's absolutely a matter of language design. Again, I'm not criticizing Rust, but a language explicitly designed to be trivially written by anyone, fast, is going to be easier to write in quickly by anyone. Imagine making that comment about Logo instead of Go. Of course Logo is more painless to write than Rust! It's a child's language. So is Go!

Rust development can't be made as easy as Swift (and it is very unlikely that what you described would be faster than Go). Even Graydon Hoare agrees that Rust is inadequate in comparison to Swift in terms of development ease:

https://www.reddit.com/r/rust/comments/7qels2/i_wonder_why_g...

I'm no stranger to languages with vastly different idioms than normal (I write APL daily), but not all languages are as quick to develop in as every other, and pretending they are is silly. Rust has some innovations, and it's by no means a bad language in itself, but pretending it wins at everything under the sun (even things it's not trying to do) doesn't reflect reality or the perspective of the original author.

You're right. What I found fascinating is how these guys theorized their way into the ballpark of what happened. They proposed eight possible future outcomes as the war unfolded and to their credit listed this one as the most likely one.

Though to be fair, the passage in context didn't so much as predict suicide but warned about a staged suicide's propagandizing impact on future generations.
No that's incorrect. All bondholders would be subject to the same terms. China has no power to enforce anything different.
That doesn't work for everyone though. I'm studying pure math and I find most applied math problems very boring. I also like solving puzzles, though. If a problem is little more than knowing which formula to use (with some manipulation) and then punching the values into my calculator then it just feels like I'm doing a computer's job.

So I think if we gear our curriculum too heavily to the applied side of things, we risk alienating some very gifted students who might otherwise go on to become brilliant mathematicians.

The reason React was made is because it's an easier way to reason about apps at scale, with many components and people working on them. As a result, there will be less errors and your team can move faster. It has nothing to do with offloading rendering to the client.
There's already extensive commentary on the organizing side of planning, but for my personal projects, much of my planning is thinking through the problem and recording my thoughts.

I've found Inkdrop[1] is quite good for that; there are a ton of them out there, but it has nice tagging and the ability to set a Status so you can have a set of notes "in progress."

I've tried a few mind-mapping tools, and can't recommend them, unfortunately. And none of these tools really talk to each other, which is disappointing.

Ask HN: How do I overcome feeling my code will be scrutinized?
I began coding in highschool in 2001 and I did all of my learning through books. A few years later, I use to post small projects on public forums. A lot of the more experienced developers at the time complete put me down for my poor programming practices and lack of knowledge and I developed this fobia of having other developers look at my work. Over the last 15 years, this has had a significant impact on my growth. I never pursued software development (even though as a hobbyist, I enjoy writing code and learning new languages). I took the sys admin route, because I'm only writing scripts and nobody cares. I don't engage in code sharing on github, I avoid meetups like the plague. I've made some personal successful projects in the past but I know my skills are severely limited due to the fact that I simply have not colloborated with more experienced developers. I want to grow as a developer, do I need to go to a therapist?

Different dementia rating scales may give different results because the study is underpowered for the effect, and/or Aducanumab is only effective in a subset of patients.

There is something to suggest that the latter is the case. The MMSE score usually becomes low relatively late in dementia. The questions are easily solvable for most non-affected people [1] and the cognitive impairment must be quite severe for a significant drop. ADAS-COG on the other hand is more sensitive, especially in early disease [2]. It would be plausible then that patients in an early dementia stage treated with a higher dose, respond, while patients in a later disease stage can not be treated using Aducanumab. (Maybe it even has a paradoxical detrimental effect in late-stage dementia, who knows?)

I would hope that they dig down in the data and find an objectively identifiable subpopulation where there appears to be significant effect, and rerun a phase III trial on that subgroup. Even if they only can treat a subset of Alzheimer patients, that's a very significant breakthrough.
