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.

getpost··on I built an app to fix my depression
Sapolsky himself struggles with depression, which he claims is genetic, IIRC. Not that I know anything, but I was struck that someone with his knowledge and intellect seemed to have given up attempting to treat it. He maintained psychological defenses that made me wonder whether he'd received adequate care.

I'm not sure where I heard this, but likely it's one of the following podcasts, which are worthwhile.

Sam Harris #91 - The Biology of Good and Evil https://samharris.org/podcasts/91-biology-good-evil/ YT version: https://www.youtube.com/watch?v=rLWzMH8psFU

getpost··on Tech firms face growing resentment of parent employees during Covid-19
There is a fairness problem, and I don't see a solution except to allow everyone to work less. Working less is not a bad thing.

As a manager, I've always accommodated parental (or other family) leave requests. I even encouraged hesitant parents or other care-givers to take paid time away from work. I don't remember ever refusing leave or pressuring anyone to return to work. This was sometimes contrary to the employer's stated policy. Had I been asked about it (and I never was) I would have made the case that it is in the employer's interest and my interest as a manger to be flexible.

I never had a request for more than a few days at a time. Obviously, requests to take an extended period (months or years) are another matter.

I remember very few requests for non-vacation, self-care time off, just the rare "mental health" day.

In my experience, it really is true that parents and other care-givers take more time off than non-care-givers. In partial mitigation, I have found caregivers to be somewhat more efficient in completing work at the office, compared to single people, especially single people under 30. Parents don't have time to waste!

EDIT: I see two fairness issues, caregivers getting more time off than other employees. And, not all managers are the way I was, and it is unfair that "my" employees had a better situation than others.

getpost··on Vitamin D, part 2: Shannon's story
D2 is the active form in plants. In humans it must be converted to D3.

getpost··on Vitamin D, part 2: Shannon's story
Can’t find a citation at the moment, but it also depends on what part of your body is exposed. Just resting your forearm on an open car window won’t do it. You have to expose your torso mid-day IIRC.

A friend left an oily rag in a bucket on a ladder where it was eventually exposed to midday sun; that was enough to ignite it. Fortunately we saw it just as it happened.
getpost··on A User Guide To Working With You
This is a good example of grandiose narcissism in the workplace, wherein there is a presumption that learning about ‘me,’ the author, is an important part of someone else’s job. Look at all the statements that start with “I!”

Rather than a long essay with a self-absorbed worldview, what might be helpful is a guide written by other people who have to accommodate this person. Just kidding, nobody should be thinking about accommodating anyone in this way or to this degree.

All those statements in the essay should be private guides to the author’s own personal development. For example, “I am frequently late to meetings,” should be taken as evidence of self absorption, poor time management, and a lack of respect for coworkers. The author needs to learn how not to be late.

getpost··on NASA Astronauts in SpaceX Capsule Make First Water Landing Since 1975
It seems to me SpaceX's secret sauce is continuous iteration on vehicles that actually fly. It's hard to see how Boeing or Blue Origin can develop expertise with any confidence their designs will work, except, apparently, by going very slowly. Of course, Boeing has somewhat of a track record, but Blue Origin was founded before SpaceX and still hasn't achieved orbit.
getpost··on ‘Success Addicts’ Choose Being Special over Being Happy
Yes, this is an aspect of secure attachment. Securely attached people prioritize relationships; relationships take time and effort and require reliability.

Insecurely attached people are usually not satisfied with relationships, and consequently don't prioritize them. The (possibly unconscious) expectation of a bad relationship is self-fulfilling.

getpost··on One hour of slow breathing changed my life
I haven't tried the one nostril approach except briefly in yoga class, but you can control your energetic/restful activation level by controlling the length of inhalation and exhalation.

getpost··on Regional Air Mobility: Why we don’t plan to operate flights under 20km
It might be less expensive due to the electrical powerplant. It will take a while before there is enough of a track record to know for sure. But, for example, electric cars are much lower maintenance than gas cars, as Tesloop as shown.

getpost··on The Four Quadrants of Conformism
I suggest not putting people into quadrants and making an us-vs-them argument. Everyone is exactly the same and also completely unique. At times, some people appear to catalyze change, but it's everyone else that actually makes the change.

There has always been an "immune" reaction to new ideas. That is not going to change for the foreseeable future. Don't worry about it, just keep innovating.

Linoleum is very eco, but highly flammable.

> I've had a flood from a broken washing machine hose before.

Oh, me too! So far my only significant insurance claim, around $70K for repairs in the mid-90s. The leak occurred while the house was unoccupied for a week.

Pro tip: you have to have receipts for all personal-property damage claims, which few people would or could have prior to everything being online. Exception: my insurer did accept a list of all damaged books with the associated cover price.

>Also, I have too much experience with rotted wood decks, this one is concrete

Aluminum decking is an excellent option. It never gets hot enough to burn your bare feet, doesn't rust, or smell like 'plastic' decking. e.g., http://www.nexaninc.com/products/decking

EDIT: Also it doesn't burn. Aluminum structural members are expensive. It's possible to use pressure-treated lumber to support an aluminum deck, although, of course, it is a toxic material.

getpost··on Schools Beat Earlier Plagues With Outdoor Classes
Traffic noise is a problem for many schools in urban areas — another reason you don’t want to open windows or teach outside.

Moreover, some schools have only small 100% paved outdoor areas.

Example: Ánimo Westside Charter Middle School (funded by Gates Foundation) https://goo.gl/maps/Wn2bu5kkh97Ygqt88

Nearby public elementary school adjacent to nature area, with ample unpaved space, somewhat less noisy, bit still problematic. Playa Vista Elementary https://goo.gl/maps/tydUVn1X9ppB7p699

(Not complaining about charter schools, but this is an interesting juxtaposition, unrelated to the main point of this topic.)

getpost··on Data structures and algorithms I actually used while working at tech companies
> why hire someone with just look-up skills before hiring someone who really tries, and enjoys the challenge

This attitude will keep you from hiring someone who will just "do the right thing," which is to look up stuff that can be looked up, and also persevere when an off-the-shelf solution won't be sufficient. Plenty of engineers will spend time trying to reinvent the wheel when it is totally unncesssary.

getpost··on Orthodox Privilege
Is there a high-pitched sound, or not? If the people in power say there's no high-pitched sound, and the people out of power are suffering from the high-pitched sound, what is "true"? There is "a truth," or "two truths," but not "the truth."

The ideal of polite conversion is that people who disagree can come to a conclusion, a "truth," that was previously inaccessible to either of them. Asserting "the truth," is a dominator paradigm privilege.

getpost··on How to Understand Things
Not stopping after the first right answer is one metacognitive strategy[1] among many. Metacognition is an area of active research.

I first heard of metacognition as a distinct discipline in connection with the treatment of insecure attachment.[2]

Metarationality[3] is an aspect or extension of metacognition.
