It is! To everyone who is considering doing a long range motorcycle trip: just go for it!

Even reading about other people's trips on ADVrider lightens my mood, and my own trips have brought me priceless memories.

If you cannot provide actual information, why would you start rumors and make vague claims?

Why is somebody "lowly like you" doing PR and insulting people [1] on hacker news?

I don't understand what you are trying to say in this comment, can you elaborate? Where should gp voice their "special love" for Linux?

If you crave for further disappointing books, I can also recommend "Do the Work" by the same author. Instead of actually doing the work, I read the book, and it hasn't helped me a bit.

I started using a stand-up desk at home and standing on a "wobble cushion" on one leg.

This is only anecdotal, but I feel it helped me getting a grip on my weak ankles and knees, my key pain points when running.

While this looks awesome, it runs really slow for me. From sending a command in Sublime to the actual execution, it takes me > 1s. This is on Windows 10, Sublime Text 3, Chrome 66.

EDIT: if I install chromeREPL, it takes ages to open the command palette (CTL+Shift+P). If I uninstall it, the problem disappears.

If you have distorted currents and voltages, you need to do this. 3.6kHz sampling captures harmonics up to 1.8kHz, which is the 36th harmonic. Power is 1/T \int_0^T U(t)*I(t)dt for periodic signals with period T, and if current and voltage cannot be assumed to be sinusoidal, faster sampling is needed.

This will never become a problem.

Take the mediterranean for example, a relatively small ocean. It has a volume of 3.75e15m3, with a mass of 3.75e18kg.

We need 4kJ/kg/K to heat up water. To heat the whole mediterranean by 1K, we need an energy of 1.5e19kJ, or 4.16e6 TWh.

In 2008, total worldwide primary energy consumption was 1.32e5 TWh, 31x less energy than needed to heat the mediterranean by 1K.

This is not even an article, it is an ad for a company (ungleich.ch) that provides github-like hosting services.

I was excited when I heard about WSL. Of course I found the name confusing, Windows Subsystem for Linux, isn't it a Linux Subsystem for Windows?

Then I realized that the COM ports are not routed into WSL. I need USB-to-RS232 converters to interface with our hardware. Of course, there is a web of contradictory blog posts and announcements when that feature will be finished - one post stating if I upgrade to Creators Update MVP Edition 120394782034785023845 Build 23904782390475 or later, I can use the feature! It took me 1h to find out what version and build of Windows I had, and 1 hour to install the new Creators Update, and 1h to reinstall WSL - and guess what, the feature was absent. What a clusterfuck.

Third that. The author's upbringing in rural communist China gives these books an amazing depth.

2018 is, after all, the year of the Linux desktop.

I was surprised to find that Ubuntu 16.04 worked better on my Thinkpad T450s than the stock Windows 10 install (which came with a lot of crapware). I had sound stutters and mult-monitor issues on Windows, and everything worked out of the box on Ubuntu.

I am glad you are bringing this up. It's impossible to cheat and skip training. I started running alpine trail (ultra) marathons three years ago, and every time I go for a >40km run in the Alps, the hammer of reality just comes down fast and hard on both mind and body.

In the beginning I have grand plans of finishing near the peak of the Gaussian distribution of my age group. After 10km I am cursing myself for not training more. After 20km I am just focusing on finishing, and after 30km on not dying.

At ETH Zurich, there is a project aiming at scaling compressed air storage to MWhs. [1]

The interesting part is that they are trying to make the storage adiabatic, i.e., they store the heat that is generated while compressing the air in a phase change material (i.e., a material that will become liquid when hot, since a lot of energy can be stored in phase transitions) and get the heat back to warm up the cold expanding gas on decompression.

The issue is that even with the phase change storage, heat will dissipate into the rock within a couple of days, making the whole process inefficient for long-term storage.

The books I read have non-trivial content and are written in an engaging fashion, so, no, I don't.

TL/DR: "I started wearing a sweatshirt and hand warmers at work, and I avoided caffeine on the days I went to the office. The pain went away, and so far hasn’t come back."

I understand that keeping back this information is a rethorical tool to force the reader to read the article to the very end, but I believe it is a dishonest strategy of keeping people reading.

"One time, [...] Steve [...] wanted me to do a keynote that happened to be scheduled on the same day as our wedding. With a big smile and full of charm, he suggested that we postpone it. We declined, but he kept pressing. Eventually my wife countered with a suggestion that if he really wanted “her” John so much, he should loan John Lassiter to her media company for a day of consulting. Steve went from full charm to ice cold really damn quick. I didn’t do that keynote."

Quite Machiavellian, asking somebody to reschedule their wedding for a keynote and being completely unwilling to return the slightest favour!

Sweet! BTW, this was made by mattn of go-sqlite3 fame.

I had never heard of "peco" before, the self-describe "simplistic interactive filtering tool" that is called if you run $memo edit. Looks pretty handy!

Counterexamples: Polgár Sisters. And basically all professional athletes, which typically start at a very young age, presumably with a parent's support (or pressure).

And let us not forget the educational masterpiece that is "Cunk on Britain".

I'd been following Madsen before the Kim Wall murder. He founded the Copenhagen Suborbitals, a (now estranged) group of very successful rocket amateurs, and he built several working submarines. I have always been impressed by his zeal and his skill to use people to help build the stuff he envisioned.

On one occasion, they used one of the submarines to drag a rocket launch platform into the ocean. How cool is that! Using your self-built submarine to launch your self-built rocket into the stratosphere.

That said, the case seems pretty clear from the outside. I have no idea why he thougt he could get away with this.

Nice! It bothers me a bit that in the first scroll plot, it says "input current (mV): -5" - not only because current is measured in A, but also because I don't know how the input is applied and how the membrane potential is measured.

I applaud the FreeCAD team for their efforts and hope it will become to 3D mechanical CAD what KiCAD has become for PCB design and schematic capture.

That said, I can get Fusion360 for free, and while I hate the fact that it's not open-source and that my files are hidden and locked away ond Autodesk's servers and that they can cancel my free "hobbyist" subscription on a whim, Fusion360 is so much easier and faster to use for my small weekend projects that I just cannot bring myself to go through the pain of learning how to avoid the random crashes of FreeCAD.

EDIT: if there is a donation page for FreeCAD, I am willing to pitch in.

I agree.

The wikipedia article on LIDAR says

"Lidar [...] combine[s] laser-focused imaging with the ability to calculate distances by measuring the time for a signal to return using appropriate sensors and data acquisition electronics."

So this is not LIDAR. Still impressive though, I love the simplicity!

I still don't quite understand how this works. Main components are:

- Laser

- Lens

- TSL1401 line image sensor

I was always under the impression that LIDAR includes a time-of-flight measurement, which does not appear to be the case here - the TSL1401 sensor has integration times and pixel transfer times in the range of dozens of microseconds, a timespan in which light travels dozens of kilometers.

Is it? I was under the impression that we are hitting physical barriers, like transistor size getting closer and closer to Silicon atom size.

I haven't tried Affinity products, but in recent times, I have started actually buying software.

I realized that I am willing to pay around 60$ for a marvelous editor (Sublime Text) or audio recording program (Reaper), in a non-subscription model, with non-cumbersome licence handling. I wish there was something similar for CAD software - something like Fusion 360, but where I can pay 60$ and be sure to be able to use it for the next 5 years.

"When someone claims that capitalism requires coercion in order to pay high salaries, the burden is on them to explain why so many high salaries exist, sans coercion, under capitalism."

I was trying to make an argument that in capitalist countries without worker protection laws like minimum wage, holidays, worker safety regulations, retirement etc (think China, industrialization-aera Europe), workers tend to be exploited by their employers, rather than receiving part of the wealth they help generate.

"will no longer redistribute the wealth to the workers, as capitalism has done for the last few hundred years"

It appears that we have vastly different opinions on how capitalism works. Capitalism needs to be coerced by laws into giving back to the workers (taxes on companies etc.) and more often than not, companies try to circumnavigate these laws.
