q_revert··on The unexpected poetry of PhD acknowledgements
I rushed mine, to the extent that my supervisor mentioned it to me a few years later... it was a reflection of my state of mind at the time, exhausted and overwhelmed.. if I ever get around to doing another one I'll give it the attention and love it deserves
q_revert··on How to make a great government website
somewhat of an aside, but really enjoyed the scrolling dynamic on this site
q_revert··on Strange Attractors
despite having a phd in nonlinear dynamics, I struggle to wrap my head around most of this stuff... but I always found is deeply fascinating.

In one system I studied we had a sequence of period doublings, which followed one of the feigenbaum constants[1]

seeing this happen in the lab, and subsequently seeing it numerically, and uncovering the analytics behind it was a worthy use of 6 years

q_revert··on Matplotlib 3.6
the extensibility of matplotlib is simply incredible to me. I've always found the main limiting factor to be my imagination, once I wrap my head around what I want a plot to look like I know matplotlib will facilitate it. An absolute marvel, and a credit to the devs
q_revert··on Tartaglia, Cardano and Ferrari – 16th Century Mathematics
exact analytical solutions are nice as a check against any numerical solutions imo. (checking the same calculations in multiple ways is handy for error catching ime)
q_revert··on Why have so many physicists shrugged off the paradoxes of quantum mechanics?
because it's really hard, and they need to publish :)

-- phd in physics

q_revert··on Neuronal Dynamics: From single neurons to networks and models of cognition
Having spent ~6 years studying nonlinear laser dynamics, it always amuses me to see bifurcation theory pop up on HN.

https://neuronaldynamics.epfl.ch/online/Ch4.S4.html

A fantastic resource on a lot of this material (basically a peer reviewed wikipedia): http://www.scholarpedia.org/article/Bifurcation

q_revert··on Unplanned Freefall? Some Survival Tips
doing the math is seldom enough ;)

*KE == kinetic energy

kinetic energy: "energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes."

in normal person terms: the energy of moving, or ~exercise, in a parallel world :)

q_revert··on No publication without confirmation
anonymous messages are sometimes very powerful, measurements that are easy to make are not necessarily the right ones to make

sometimes you get snowed in, often you get snowed under

q_revert··on Examples of unexpected mathematical images
a spectacularly unbiased example, multiple measurements, experimental and simulated, of the same thing :)

q_revert··on All I Possess
a book, with some strikingly similar ideas: https://en.wikipedia.org/wiki/The_Gospel_According_to_Larry
q_revert··on Being a Data Scientist: My Experience and Toolset
Using a term like nonlinear science is like referring to the bulk of zoology as the study of non-elephant animals.

q_revert··on Data diversity: Preserving variety in data sets should aid machine learning
I think this is the paper, which oddly isn't linked in the article:

https://arxiv.org/abs/1509.01618

q_revert··on Ask HN: What cool development languages/tools changed your career?
matplotlib. at times it can be tiresome, given the multitude of ways it's possible to do things, but it's always possible
q_revert··on When to post to Hacker News and how many points to make it to the front page
I've only made two submissions. By some odd coincidence both made it to #1, which has scared me off making any further submissions for fear of ruining my perfect score! :D

As an Irish citizen I was wondering which countries our British counterparts could get to that we couldn't :)

q_revert··on How Google Works
I'm a physicist (semiconductor lasers), now doing tech support, it's a big change for me, but so far it's been great
q_revert··on How Google Works
I started work at google pretty recently, and expressed an interest in working on a particular project. I made some notes about some of my ideas, and was putting some stuff together to show to one of the teams, to get some input before prototyping.

I asked a senior team member to have a look at the notes I had made, and see if they were ready to show to the wider team.

His advice?

"Go build something, then we can have meetings"

Coming from an academic background I find this type of thinking very refreshing.

q_revert··on Chromeos-apk – Run Android APKs on Chrome OS, OS X, Linux and Windows
Another vote for firefox OS here, I definitely think they're making a better effort than most in this space. The fact that firefox is targeting entry level devices in a serious way is another positive for me. I've been using a ZTE open as my primary device, and although the hardware is absolutely awful, I've managed to get by, mostly just because of a sentimental attachment to firefox.

I agree it's somewhat unlikely to be too successful, but I definitely think they're at least aiming in the right direction.

q_revert··on Show HN: The Markdown Resume
agreed, this is exactly the sort of thing for loops in shell are useful for.. incidentally, in zsh you can do this with

   for f (*.md) pandoc $f --to html > $f:r.html
personally I find that when I can fit a loop on a single line in zsh I'm much more inclined to use them
q_revert··on Neovim's Next Feature Poll
> What's more, if I record a macro and run it, then realize after it that I want to do a small addition, I have to go through all the "setup" steps again - go back to the start, re-record, add the logical of finding the next block, and so on. I can't just visually see the situation and say "oh yeah, why don't I add this little tweak".

this is very doable, lets say you record a macro to 'a'

    1. q:
    2. let @a='
    3. ^r^ra to put in the current contents of the macro
    4. edit as you see fit

    --- you should now have something like ---
    let @a='contents of macro'
    
    5. ???
    6. profit
q_revert··on Firefox and Flux: A New, Beautiful Browser is Coming
http://i.imgur.com/Ueqq29i.png is what my current vimperator browsing window looks like (ff27), the new changes make this very difficult to replicate via changes to userChrome.css, but hopefully, as it gets more exposure, these things will get ironed out
q_revert··on Hackers Lurking in Vents and Soda Machines
the output of htop is almost distinguishable here

"Companies scrambling to seal up their systems from hackers and government snoops are having to look in the unlikeliest of places for vulnerabilities."

q_revert··on Vim: Spacebar as leader key, CapsLock as Esc
I use <space> as my Easymotion leader..

https://github.com/Lokaltog/vim-easymotion

it's well worth a look, gives you super quick fine grained movement

similarly

    inoremap jj <ESC>
to take you from INSERT mode to NORMAL mode is nice
q_revert··on Shell script mistakes
and another reason to use zsh is the incredibly nice looping syntax, for example, this is the same as

  for fic (**/*(.)) doSomethingWith $fic
I find the fact that it fits in a single line makes me much more likely to use it in everyday shell use.. though I'd still revert to bash for scripting
q_revert··on Text-based terminal screencasts
the ability to copy/paste is particularly useful in this case, given that that's what most people end up doing anyway.. particularly for more complicated commands
q_revert··on PuTTY Tray
just in case there's anyone who hasn't seen it before, Xming[0] combined with {putty,kitty,alternative} allows you to `ssh -X host`

q_revert··on Illegally climbing the Golden Gate bridge at dawn (2011)
"the bridge" is a fantastic documentary which looks into issues, and talks with some of the people who lost family to depression/suicide on the Golden Gate bridge. Well worth watching

q_revert··on Hacker News Karma Superstars
what might also be interesting is to see how karma is accrued.. from a huge number of submissions, or from a large number of insightful comments, or what the breakdown is..

for example, i've made two submissions, both making it to the #1 spot, and have been afraid to submit any more lest my streak be ended

some measure of quality over quantity would be nice :)

q_revert··on Here’s Why Firefox is Still Years Behind Google Chrome
to me vimperator isn't just about having a few vim bindings here and there, it completely redefines the browsing experience... also, when you "f" to find links, you can just enter a piece of the url string and vimperator opens it.. either way, it doesn't matter much..

vimium is a lightweight clone of vimperator, if that's what you want then of course you'll prefer it..

these "problems" you're talking about in vimperator are features once you actually embrace it and use it properly. it's a power user's tool.. and should be recognized as such..
