jepper··on Review: An iPhone Case That Claims to Boost Your Reception
Don't journalists get a course in basic statistics? Would solve a lot of these types of "reviews".
jepper··on Tell HN: Wear a Helmet
In the Netherlands we have dedicated cycling lanes along larger roads and car drivers that are comfortable with cyclists. Almost everbody cycles, nobody wears helmets. And we haven't got a raised head injury mortality or paralysis rate because of bike injuries. I've never had an injury and probably traveled more kilometers by bike than any other means of transportation.

I do wear a helmet while road biking but that's a whole different topic.

jepper··on The Man Who Made the UK Say “I’m Sorry for What We Did to Turing.”
Congratulations jgrahamc ! Thank you for your persistence! Truly horrible what happened to somebody who did a lot for Britain, computer science and the world.
jepper··on New Startup Raises $100M for Portable Ultrasound
An you can feed a software consultant on 1 dollar a day.

The price in medicine is mostly not the hardware but the required expertise to analyse the data. Ultrasound imaging is not easy. The american health system is very expensive though, a ultrasound is around 50 euro's here.

That said, 3D ultrasound can have tons of other applications not just in diagnostic medicine. Real time surgcial feedback in soft tissue, yes please!

jepper··on Lecture 5, How to Start a Startup: Peter Thiel
Yet, a 1000 years from now, nobody except maybe historians will know who Peter Thiel was. Except for Crassus there havent been many business men that survived the oblivion of time.

Eistein will certainly join the ranks of scientific giants.

jepper··on Russian M-125 Fialka Cipher Device
Really interesting post. Does it have the same weakness as Enigma devices, i.e. that the input char can never become the output char ( encrypt(a) is never a)? This significantly reduces the search space.

jepper··on Electric Velomobiles: fast, comfortable, and more efficient than cars
I see quite a lot of these vehicles in fly by on the dutch roads, they use the road and not the bicycle lane. They are becoming quite popular. Luckely we don't have that many "tractors" as we call the big SUV's. Drivers already have to mind the bicyclists so the velocycles are just another road user.

When i'm on my racing bike i can barely keep up with the non electric velocycles, often driven by 40 year old or so professionals commuting. They are incredibly fast for little energy expended.

jepper··on Show HN: YouFM - A new way to listen to music on Youtube
Nice site, one of the nicest looking youtube streaming sites. Good clean UI.

You need a favicon though, was hard tot find it amongst all my tabs.

jepper··on Global Internet slows after 'biggest attack in history'
Its most certainly fake. That is dutch riot police. We don't have SWAT teams but "arrest teams". They definitely don't wear white helmets. They definitely don't just trow around flash bangs. And the kicker, knowing dutch police bureaucracy, they did not get a refund this quick.
