getpost··on A request for Pinboard old-timers
@idlewords, I renewed for a year, having signed up in 2014. For me, it's an essential service.

I didn't receive any email about this; the most recent message I have is a password reset in 2017.

Aren't the deep discounts for multi-year renewal tantamount to recapitulating the problem with the original one-time sign up fee? i.e., having to run the service with no recurring revenue.

getpost··on A request for Pinboard old-timers
I use pinboard a lot, and I'm inclined to pay. I'm curious to see all my old delicious links!

But, having said that, I'm planning to replace pinboard with my self-developed bookmarking site on repl.it.

I'm in the same boat. That's why I use repl.it[0] for nearly all my programming now. Haven't tried jupyter on repl.it, but here's[1] the first DDG result, which suggests jupyter is supported.

getpost··on I can’t work the hours I did in 2020 again yet struggling to see how to avoid it
My own experience is that startup employers really do have unrealistic/over-optimistic expectations of what's actually required to achieve a certain result. Anything worth doing in the startup world hasn't been done before, so it's usually not possible to invent it on a schedule.

People who will throw something together are heroes, but very often the result is complete crap that has enormous costs if it gets adopted as a standard. I'm being only slightly facetious asking, how much has humanity been set back due to the fact that less than two weeks was spent inventing Javascript? Maybe they should have spent an extra week or two on it and saved millions of person-years down the road [ h/t the recent repost of https://www.destroyallsoftware.com/talks/the-birth-and-death... ]

At the same time, my own psychological makeup made me vulnerable to trying to meet those unrealistic expectations, and that's on me. It took decades to really figure out what's going on, and ultimately it's a matter of acceptance rather than actionable change, although change is possible. With so much of our capabilities and challenges being unconscious, I continue to marvel at the miracle that anything gets done at all.

Yeah, Musk might be able get away with this, since I expect many key employees will be attracted by much lower housing costs out of state. Texas has high real estate taxes, but not high enough to offset savings on house prices.

How do you do this exactly?

getpost··on Sleep duration is associated with brain structure and cognitive performance
Given the time span, I assume the answer is, "no," but are you taking any dietary supplements? DMAE? Galantamine? If yes, stop taking them (after consulting with an appropriate heathcare provider).

EDIT: My own experience with DMAE is that it made some dream memories hard to distinguish from reality. Did that happen only in a dream? I wasn't so sure sometimes.

getpost··on Maddy: Composable all-in-one mail server in Go
EDIT: Oh, yes, I see, I am not sure why anyone would do this. Maybe someone who had an address or two they want to keep at the lowest possible cost. I'm not sure how email is managed for such accounts, but it's possible Dreamhost will take care of the setup, so maybe you don't have to interact with the web control panel, which might be intimidating for some users. Could also be a legacy arrangement for an older product offering.

Original reply:

Buying domain hosting gives you "unlimited" email addresses, so domain hosting is cheaper as soon as you need 3 or more addresses.

3 addresses x $2 = $6/mo for email vs $4.95/mo for any number of addresses. I have a friend who is married with 4 children. He pays $4.95/mo for 6 addresses. You don't have to actually host an http domain to get email hosting that comes with domain hosting.

"unlimited" in quotes because obviously there are some limits and service terms. You can't start a competitor to gmail with a $4.95/mo hosting account.

And, like most kinds of work these days, science progress is mainly collaborative, rather than the result of one independent thinker.

pg seems predisposed to dichotomous thinking. This could be about his rhetorical style. It's easier to write an essay, or a screenplay, with good guys and bad guys. The world is more like a novel now, with multiple independent processes in shades of gray.

The advantage is you can have "unlimited" email accounts and "unlimited" domains for $5/mo. One domain registration is even included.

Dreamhost offers email hosting for any number of addresses “free” (at no extra cost) in all plans except the starter plan, $4.95/mo.

getpost··on Google plans to shut down Google Voice integration with classic Hangouts
>Next year, Chat will become available as a free service—both in the integrated experience in Gmail and the Chat standalone app.

It was great when Chat [EDIT: This was Google Talk, I think.] was integrated within gmail, both as a ui, and the fact that chat messages were mixed-in with your regular emails, and available for searching. I don't remember when this was removed, but I haven't used it 10+ years. Somehow I doubt the new Chat will work the way it used to, but I hope so.

EDIT 2 (off topic): I tried to look at Google Chat, but first Google wanted me to answer some survey questions, so I agreed to. There's no (apparent) way to navigate the survey questions or revise your replies. I clicked through one question accidentally without answering it. For another question, I mistakenly answered the opposite of what I meant to. Garbage-in, garbage-out.

EDIT 3: After clicking "Get Started" in Google Chat, it appears this is only for groups a la Slack. Why can't I just IM other people with gmail addresses in my address book?

getpost··on Vitamin D improves survival in Covid-19 elderly patients
This is hardly worth writing up for n=57. I scanned the full text and didn't see any notation regarding vitamin d blood levels in patients, which would have been useful to know. Maybe nobody wanted to pay for those tests? A helpful result would be something like, "blood levels of X ng/ml improved survival rates Y% with a confidence interval of Z."

Instead, we have an odd and vague dosage, "80,000 IU vitamin D3 every 2–3 months." I gather this study was constructed given the supplement regimen that was in-place. Why were the patients being supplemented that way? What standard of care is that?

getpost··on American Airlines Is Quietly Bringing Back the 737Max
Mechanically linking is heavier than fbw/electrical/fiber optic linking, and what's the point if there's no mechanical linkage to the control surfaces?

With the fbw system, the software makes the choice on how to interpret the control movement, use one or both? If one, which one?

EDIT: Maybe you mean that a mechanical linkage would provide a feedback mechanism, so that one pilot would know if the other pilot was attempting an input? I don't know if there's force feedback on Airbus flight controls.

getpost··on American Airlines Is Quietly Bringing Back the 737Max
The advantages of fly-by-wire are too good to pass up, so that leaves the question of how to design an FBW system.

A high school teacher of mine in the 1970s predicted an accident like AF447. He framed it this way: the 'American' approach is to implement FBW to always do what the pilot inputs indicate, whereas the 'French' approach is to do the right thing, and override the pilot if the FBW 'knows' better. That's an interesting cultural cultural consistency as well!

So, the 'American' approach is better if the sensors are not working as expected, and it makes the software simpler. The 'French' approach is better if the pilot is wrong, but both the sensors and the software must be working perfectly. Everyone makes mistakes, and all software has bugs. What to do?

(In reality, some 'judgement' is needed by the software, even in the American approach.)

EDIT: That said, some of the design choices in the Airbus FBW are baffling, such as making the control input the average of two different inputs. I like to think AF447 is less likely to have happened in a Boeing ship, although the ulitimate cause of the crash was a pilot making what amounts to a beginner mistake.

getpost··on Show HN: Perfect Pitch Ear Training
I was intrigued by this paper. Haven't tried it though.

Valproate reopens critical-period learning of absolute pitch https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3848041/

Absolute pitch, the ability to identify or produce the pitch of a sound without a reference point, has a critical period, i.e., it can only be acquired early in life. However, research has shown that histone-deacetylase inhibitors (HDAC inhibitors) enable adult mice to establish perceptual preferences that are otherwise impossible to acquire after youth. In humans, we found that adult men who took valproate (VPA) (a HDAC inhibitor) learned to identify pitch significantly better than those taking placebo—evidence that VPA facilitated critical-period learning in the adult human brain. Importantly, this result was not due to a general change in cognitive function, but rather a specific effect on a sensory task associated with a critical-period.

getpost··on What is the PDP-11 instruction set?
Ah, my first love! The first assignment was to hand-translate a program to do keyboard input into machine language, and then use the console switches to enter the machine language, so I could then type in more machine language. After a couple small programs, I got to use the assembler! It was thrilling! No more hand translation! I wish CS was still taught this way.

getpost··on Ask HN: Essential skill needed to be a programmer?
For me, this is the attitude that there is always something wrong with the code, there are always errors, and it's a question of whether I've found enough errors so the program is sufficiently reliable.

But, I don't think this is the main skill in programming. Good programming is the iterative application of concision and honesty, tempered by the ability to interrupt overfocus so as to find the right balance between perfection and getting something done.

getpost··on Trello co-founder Michael Pryor on pandering to power users
This is a perennial issue in software design and business, something I struggled with in the 1980s, and I don’t think it was a new problem then.

Most users need only a few features and the UI can be made very simple and easy to learn. However, a small percentage of users need more powerful/hard to use features, and the needs of these users usually determine which product is purchased.

Since it’s advantageous for everyone to use the same product, most corporate employees will be stuck with a hard to learn/use product. Vendors of low-end/easy to use products won’t be successful selling to the corporate market.

What’s different now is that there is a large market for inexpensive easy to use phone apps selling to individuals. You can make a living selling to that market, but you will never be as big as a company that sells an expensive hard to use product to the corporate market.

getpost··on Employee works for both Google and Facebook from home
As an aside, I remember nonsense clauses in Incentive Stock Option agreements. Notably, there was a non-compete clause and also a paragraph stating that the clause was not enforceable in California (and I was in California).
getpost··on Employee works for both Google and Facebook from home
In the USA? I've never had an offer letter that made a statement like that, nor did I ever sign an offer letter. I interviewed for the job, got a verbal offer over the phone, received a written letter with one or two sentences confirming the start date and salary, and that's it!

EDIT: I'm referring to highly compensated professional jobs. In two such positions, I only received a verbal offer, and there was nothing in writing. Normally, I'd insist on something in writing, but in these cases, I was hired by someone I trusted.

getpost··on Embedded PDF viewer in Firefox 81 supports filling forms
That's my point. Other than printing a nice looking form (which includes faxing), the content of the field data is hard to reuse. Searching PDF content on your own hard drive is problematic.

Are there utilities that extract PDF field data and submit it to a database? I'd be grateful to see examples.

What about field validation? The PDF may have some minor validation, but that's no substitute for the validation done in a DBMS.

If you want users to be able to save a nice looking form, you'd still want the data entered online directly into a DBMS. I'd offer a "download PDF of your input" as an option, for example.

getpost··on Embedded PDF viewer in Firefox 81 supports filling forms
“After entering data into these fields you can download the file to have the filled out version saved to your computer.”

What’s the use case? Printing out filled-in forms? But otherwise, who would want the PDF in electronic format? It doesn’t seem like a practical way for users to submit data.
