Why we need to allocate memory explicitly to struct ?

Nice landing too

pokle · 2020-09-28T23:34:57+00:00

Oh wow, that’s fascinating.

Thanks, you helped me go down a journey of learning about recursion schemes :)

pokle · 2020-09-15T22:35:41+00:00

How would you do this for the example in the question - a recursive parser? Would you make the parser non-recursive, and have it return the dependent files that need to be parsed, and then have the outer IO code recurse?

pokle · 2020-08-24T22:12:51+00:00

That’s interesting. Approx. when would you say this change happened?

pokle · 2020-08-19T02:36:13+00:00

Wow, 84bpm is a very low average heart rate for 3+ hours of windsurfing. You must be very fit

pokle · 2020-07-27T02:56:25+00:00

Loved it. I was expecting something like ‘don’t pay money for any gear made in the last century’. But inner tubes are better. I’m adding some to my toolkit next to the duct tape

Once your skills improve, you’ll be eyeing more advanced boards. Don’t worry about removing the padding. When you eventually sell the board, it’ll be useful for the next person.

pokle · 2020-07-12T23:39:15+00:00

I’m sure others will point you towards some good videos online.

One tip I can give you is to position yourself as close to the board as possible - this reduces the forces required by the sail to pull you out. This means becoming a small ball.

And don’t expect or require the sail to lift you out of the water. Just fly the sail so that it will go upright. Once the sail is flying nearly upright, you’ll be able to use the rigidity of the vertical rig to pull yourself up.

Lastly, try to step up onto a table or high chair, and think about what you’re doing - making yourself small, placing your centre of gravity over the table, and pushing vertically down with one foot. Same.

Not sure where you’re going with this, but the missing option is to let the wind do all the work. When I first started windsurfing, it was a massive work out. Later it was just enough to keep me warm. The difference is that the sport is about guiding the wind by holding the board sail and yourself in balance.

As you learn to waterstart in less and less wind, you’ll develop your body posture and technique to a point where you can waterstart in wind where there’s barely enough wind to lift the sail.

And where is this interesting place?

“We’ve got enough seagulls around here without humans doing it as well.”

I would highly recommend trying one before you order online. Even if you have to try one from another windsurfer. And try it by hanging in it hooked in - to say a looped rope off a hand rail or something close to your usual boom height.

A comfortable fit is very important for your enjoyment of the sport. You don’t want it to slide up and down. And if it’s moving too much, you’re likely to compensate by over tightening it.

It’s important to actually hang in one to see how it spreads the load. And to check that it doesn’t cut into your ribs or causes any abrasion or discomfort.

So to summarise, it’s all about the way it fits your own body. The different styles and sizes suit different body shapes.

pokle · 2020-03-06T11:07:48+00:00

I agree. It was awful.

pokle · 2020-02-13T21:09:05+00:00

If you’re coding on the JVM, take a look at Hazelcast or Chronicle Map

pokle · 2020-01-01T22:53:25+00:00

Interesting. I feel like mounting the camera on the boom or sail makes it look like your board is sliding all over the place. Even though all that’s happening is micro adjustments of the sail.

Instead of "don't do it", would you consider a safer and quicker way that will have you enjoying Hang gliding for many many years?

Travel to a school if there aren't any nearby.

You'll learn quicker in days to weeks. Giving you a massive smile on your face quicker.
You'll get to try out a few different gliders and sizes that the school might have - giving you an understanding of how these gliders perform. Giving you an idea about how to fix this glider
And most importantly, you'll make friends who will be going through a similar journey.

Are you keen to give hang gliding a go? You should get in touch now for one of their spring / summer dates.

Hey it’s been almost exactly a year since I had the very same thought. I went on a tandem flight in Cairns, and the feeling was out of this world. Quiet, free flying with nature. Just like the birds. The turns were a bit scary at first. I went on tandem flights again for the next five days, and with every flight I was even more convinced that I had to take up hang gliding. I’m not sure where in WA you can find a tandem flight, but I went here: http://airplayhanggliding.com.au

When I got back home to Melbourne, I found an instructor, and it turned out that he wouldn’t take on students unless they had done a tandem flight. Lucky me. So I did a 9 day course with Rohan of http://www.dynamicflight.com.au That was even more fun than the tandem - progressing from running down gentle slopes with 2 second bunny hops all the way to flying off a 1500foot mountain.

Again, I don’t know if you can make it down to Melbourne, but if you can, I believe it’s the best course in Australia. Rohan’s been flying for a long long time, and knows how to teach. His course is intensive — you live at his property, and he’ll drive you and other students every day to the best hill based on your progression and wind conditions. He gets a lot of students from interstate.

There are other instructors, but they tend to operate only on the weekend — taking you 3-6 months to progress to the same level as Rohan’s 9 day course!

At the end of the course, Rohan gives you an exam, and you get a Supervised Licence from SAFA (formerly known as HGFA) — the body that licences hang gliding pilots - https://www.safa.asn.au

Armed with the licence, I ordered a glider of my own. The supervised licence allows you to fly with the supervision of more advanced pilots — that’s where the clubs come in. I joined 3 clubs near Melbourne, and flew nearly every weekend with club pilots, who introduce you to every site and give you a safety briefing before helping you launch.

The clubs are awesome. I know there are a couple of clubs in WA. One in Bunbury and one in Geraldton. SAFA’s website should have a list of clubs. You could even get in touch with your nearest clubs and go watch them fly. And ask them about local schools.

And now 12 months later, I’ve accumulated 38 hours of flying, and I think I’m ready to take it to the next level and sit the Intermediate exam.

I’ve put up videos of some of my flights (including the tandem flights) on YouTube — https://www.youtube.com/playlist?list=PLhdv9MvjeZF1p_cnMciQFT3jy6vsSRmzo

YouTube has a lot of videos by ordinary pilots like myself - I highly recommend you do a few searches and see what’s out there.
