He's using an odd defintion of suicide burn - kill your orbital velocity, drop to the surface, then kill that velocity just in time. That method is inefficient. However, suicide burn properly refers to the final maneuver. Its the most efficient method of landing from any trajectory that intersects the ground. Any other method takes longer, which means you're spending more time fighting gravity and have more velocity to burn off overall.

Manual suicide burns are actually rather easy to time. When you're on a (preferably shallow) trajectory impacting shortly behind the target, go to map view, make a full stop maneuver node directly above the target, and check estimated burn time, let's say it's N. Then just execute the maneuver almost exactly like a regular maneuver, i.e. start burning full throttle towards maneuver node at T minus N/2, adjusting in radial/antiradial direction if you feel like you're falling too fast or too slow. While burning, if you need to land somewhere specific, make sure to constantly adjust your trajectory so it always goes straight over the target in map view, overshooting the target by a bit (the anti-target marker helps). When you can't zoom further into map view, switch to ship view. For the close approach, make sure your retrograde marker stays directly below the anti-target marker. As the anti-target marker approaches the up pole, make your retrograde marker approach the anti-target marker. This way, you should land directly on top of your target. When you're close enough, as usual, land by snapping to the retrograde marker.

Mechjeb is a great way to see how it is done. If you want to do it yourself, there's a few different methods. GoSlash27 has a thorough explanation of  one here.

wait, what does this guy mean that the suicide burn is "hugely wasteful of fuel" ???

Isn't the most efficient way to traverse a gravity well (or anything) to burn for as short a time as possible at the endpoints of your journey?
Not quite, you need to change your periapsis marker to almost intersect with your landing site, which is more efficiently done at the preceding apoapsis, but less accurately so.
Then you need to kill velocity before hitting the ground, the most efficient way of doing that is air braking with or without parachutes. Or lithobreaking. Of course the final braking burn or whatever moves the final periapsis marker which you need to take into account.

I just started playing yesterday. Jebediah Kerman burned to earth like a North Korean missile and was incinerated along with all his science. Dammit. Valentina! Get in the rocket!

This thread needs some life. I've started a new career game with a bunch of USI packs, I intend to make an undersea base on laythe.
Oh and replicate a bunch of stupid shit from youtube, because yolo.

I really need to play this game again. I still haven't ever gone to another planet

I can't replicate are the welding mod Kerbal cloning bug. My Ker-popcorn machine shall go undeveloped.

Working on some science!
Anybody know how to make infernal robotics not suck? :(
I'm tying to make a simple free swinging hinge but parts not clipping makes it hard.
I was hoping to be able to set a free swinging washer to only swing in one direction. Or alternatively have one of the IR hinges be unpowered so it would just swing when impacted by a flying Kerbal.

Same. Is there any idea when it's going to come? I thought it was supposed to hit months ago.

1.1 is nearing, I think it's actually out in the wild among the experimental testers. Wouldn't be surprised if it still took a few weeks still though, that was a massive undertaking going from unity 4 to 5.

They just pushed the antenna system back beyond 1.1 so probably soonish. I'd estimate 2-3 weeks

they finally fixed the gear key so you need to hit it only once first time, allegedly, and the rest are bugfixes. luckily porting to playstation didn't take development time eh?

That was a major bummer. 

I can keep using RemoteTech, but they never updated the RT flight computer to be more in line with the new stock autopilot / pilot skills.  And I always felt like the antennas and cores never got re balanced against the new versions, so I was looking forward to something that meshed together better with the stock tech tree.

Oh well.  I guess I'll wait until 1.1.5 or 1.2 to really start playing again.  1.1 will doubtless be riddled with bugs related to the major overhaul, anyway.
