Ask HN: Favorite note-taking software? | Hacker News
Ask HN: What is your ideal note-taking software and/or hardware?: https://news.ycombinator.com/item?id=13221158

my wishlist as of 2019:
- web + desktop macOS + mobile iOS (at least viewing on the last but ideally also editing)
- sync across all those
- open-source data format that's easy to manipulate for scripting purposes
- flexible organization: mostly tree hierarchical (subsuming linear/unorganized) but with the option for directed (acyclic) graph (possibly a second layer of structure/linking)
- can store plain text, LaTeX, diagrams, and raster/vector images (video prob not necessary except as links to elsewhere)
- full-text search
- somehow digest/import data from Pinboard, Workflowy, Papers 3/Bookends, and Skim, ideally absorbing most of their functionality
- so, eg, track notes/annotations side-by-side w/ original PDF/DjVu/ePub documents (to replace Papers3/Bookends/Skim), and maybe web pages too (to replace Pinboard)
- OCR of handwritten notes (how to handle equations/diagrams?)
- various forms of NLP analysis of everything (topic models, clustering, etc)
- maybe version control (less important than export)

- Evernote prob ruled out do to heavy use of proprietary data formats (unless I can find some way to export with tolerably clean output)
- Workflowy/Dynalist are good but only cover a subset of functionality I want
- org-mode doesn't interact w/ mobile well (and I haven't evaluated it in detail otherwise)
- TiddlyWiki/Zim are in the running, but not sure about mobile
- idk about vimwiki but I'm not that wedded to vim and it seems less widely used than org-mode/TiddlyWiki/Zim so prob pass on that
- Quiver/Joplin/Inkdrop look similar and cover a lot of bases, TODO: evaluate more
- Trilium looks especially promising, tho read-only mobile and for macOS desktop look at this: https://github.com/zadam/trilium/issues/511
- RocketBook is interesting scanning/OCR solution but prob not sufficient due to proprietary data format
- TODO: many more candidates, eg, TreeSheets, Gingko, OneNote (macOS?...), Notion (proprietary data format...), Zotero, Nodebook (https://nodebook.io/landing), Polar (https://getpolarized.io), Roam (looks very promising)

LeetCode - The World's Leading Online Programming Learning Platform
very much targeted toward interview prep
This data is especially valuable because you get to know a company's interview style beforehand. For example, most questions that appeared in Facebook interviews have short solution typically not more than 30 lines of code. Their interview process focus on your ability to write clean, concise code. On the other hand, Google style interviews lean more on the analytical side and is algorithmic heavy, typically with multiple solutions to a question - each with a different run time complexity.

Why is reverse debugging rarely used? - Software Engineering Stack Exchange
(time travel)

For one, running in debug mode with recording on is very expensive compared to even normal debug mode; it also consumes a lot more memory.

It is easier to decrease the granularity from line level to function call level. For example, the standard debugger in eclipse allows you to "drop to frame," which is essentially a jump back to the start of the function with a reset of all the parameters (nothing done on the heap is reverted, and finally blocks are not executed, so it is not a true reverse debugger; be careful about that).

Note that this has been available for several years now and works hand in hand with hot-code replacement.
As mentioned already, performance is key e.g. with gdb's reversible debugging, running something like gzip sees a slowdown of 50,000x compared to running natively. There are commercial alternatives however: I work for Undo undo.io, and our UndoDB product does the same but with a slowdown of less than 2x. There are other commercial reversible debuggers available too.

Based on GDB, UndoDB supports source-level debugging for applications written in any language supported by GDB, including C/C++, Rust and Ada.

Overcoming Bias : On the goodness of Beeminder
There is a lot of leeway in what indicators you measure, and some I tried didn’t help much. The main things I measure lately are:

- number of 20 minute blocks of time spent working. They have to be continuous, though a tiny bit of interruption is allowed if someone else causes it
- time spent exercising weighted by the type of exercise e.g. running = 2x dancing = 2 x walking
- points accrued for doing tasks on my to-do list. When I think of anything I want to do I put it on the list, whether it’s watching a certain movie or figuring out how to make the to do list system better. Some things stay there permanently, e.g. laundry. I assign each task a number of points, which goes up every Sunday if it’s still on the list. I have to get 15 points per day or I lose.

Valuing Alternative Work Arrangements
The great majority of workers are not willing to pay for flexible scheduling relative to a traditional schedule: either the ability to choose the days and times of work or the number of hours they work. However, the average worker is willing to give up 20% of wages to avoid a schedule set by an employer on a week’s notice. This largely represents workers’ aversion to evening and weekend work, not scheduling unpredictability.

A sobering thought | West Hunter
All this has an obvious implication that I have never seen discussed. If breathing two atmosphere of nitrogen is like having one drink, what would people be like if they were breathing a zero-nitrogen mixture? The natural conclusion is that they would be one drink under sober. Technically, they would be slightly knurd.

They should have slightly faster reflexes. Actually, this is known to be true, from studies of pilots breathing pure oxygen. In other respects, you would expect that the changes would be in the opposite direction to those caused by intoxication. Instead of a warm glow, a bit of dysphoria, Since a little narcosis causes a mild impairment in reasoning and judgment, you might see a mild improvement. This could be important, since the world suffers from a glaring shortage of good judgment.

If this idea is correct, how would we go about implementing it? Pure oxygen isn’t the right approach. The normal three pounds of O2 pressure, by itself, is too low: buildings would implode. A full atmosphere of oxygen is bad for your health. Obviously, we would want a full atmosphere of pressure, 80% helium and 20% oxygen. With that, you need to make a building airtight, but that’s all: there are no structural problem. This all costs money, so we (government and market) would provide this boon to people whose intellect and judgment are of unusual importance. The doors of Congress and the White House would be replaced by airlocks. You’d see top-notch research professors wearing breathing masks and carrying an air tank. Any professor walking across campus with a bare face would be low-status, probably a sociologist or cultural anthropologist. High-class hedge funds like Renaissance Technologies would put their whole campus under a transparent dome.

Experimental Psychologist wanted: https://westhunt.wordpress.com/2017/09/28/experimental-psychologist-wanted/
I mentioned this a few years ago: there is reason to suspect that just as an increased pressures of nitrogen has a narcotic effect, a zero-nitrogen breathing mixture [ presumably heliox] might leave you abnormally sober. On oxygen, I’ve felt something like that – anyone have the same experience?

Anyhow, someone is interested in checking this out. So I need an experimental psychologist.

Home Page << Autobiographical writing software designed to stimulate psychological growth; Self Authoring

I’ve been slowly working my way through Triver’s book Folly of Fools. Chapter six reviews the many amazing benefits that appear to arise from having people write about their troubles. For example:

>Writing about job loss improves one’s chance of reemployment. This sort of writing appears to be cathartic – people immediately feel better. More striking, at least in one study, is a sharply increased chance of getting a job. After six months, 53 percent of writers had found a new job, compared with only 18 percent of non writers. One effect of writing is that it helps you work through your anger so it is not displaced onto a new, prospective employer or, indeed, revealed to the employer in any form.


This suggests an easy way to increase employment, at least if the problem is employee attitudes. Digging more, I found this ’01 review, which seems to confirm the benefits of writing therapy. It all does seem a bit hard to believe, but stranger things have been true.


Not Learning From Failure—the Greatest Failure of All: https://journals.sagepub.com/doi/abs/10.1177/0956797619881133
Our society celebrates failure as a teachable moment. Yet in five studies (total N = 1,674), failure did the opposite: It undermined learning.
Why does failure undermine learning? Failure is ego threatening, which causes people to tune out. Participants learned less from personal failure than from personal success, yet they learned just as much from other people’s failure as from others’ success. Thus, when ego concerns are muted, people tune in and learn from failure.

Quiver | HappenApps
would be interesting to compare this w/ Workflowy (maybe keep Workflowy for most stuff but try out Quiver on a software side project)

biggest problems:
1. linear rather than hierarchical
2. lack of custom preamble (a limitation of MathJax). you can only define macros

both definitely are side effects of targeting programmers working on individuated projects rather than universal notetaking

What is up with carbon dioxide and cognition? An offer - Less Wrong Discussion
study: http://ehp.niehs.nih.gov/1104789/
n=22, p-values < .001 generally, no multiple comparisons or anything, right?
chart: http://ehp.niehs.nih.gov/wp-content/uploads/2012/11/ehp.1104789.g002.png
- note it's CO2 not oxygen that's relevant
- some interesting debate in comments about whether you would find similar effects for similar levels of variation in oxygen, implications for high-altitude living, etc.
- CO2 levels can range quite to quite high levels indoors (~1500, and even ~7000 in some of Gwern's experiments); this seems to be enough to impact cognition to a significant degree
- outdoor air quality often better than indoor even in urban areas (see other studies)

the solution: houseplants, http://lesswrong.com/lw/nk0/what_is_up_with_carbon_dioxide_and_cognition_an/d956

except that environmental instability tends to be harder on more 'complex' adaptations and co2 ppm directly correlates with decreased effectiveness of cognition-enhancing traits vis chronic low-grade acidosis

What is the best office chair? - Quora
I tried a lot of high end office chairs and settled on a Soma Comfort tall back chair. I am tall and have RSI and both of those affected my choice so it might not be the best for you, but it's definitely worth trying out. They don't sell direct so you have to find a place near you that carries them.

There are some pictures here: SomaComfort Tall Back Chair
