Japanese corporate | Zurich, Switzerland | FULL-TIME | ONSITE (preferred) or REMOTE | EU/EFTA

We are a global manufacturing leader in optical fiber communication systems and electronic components that supplies telecom and carmakers worldwide. Our current activities relate to upcoming wireless technologies and sensors based on mmWave for the automotive and mobility industries.

I am looking for a (Senior) Software Engineer with strong expertise in HPC to join our R&D team. Your main role is as an expert in the development and implementation of high-performance routines from our state-of-the-art algorithms.

We look for someone with a liking for software craftmanship, experience with developing compilers and eating vfmsubadd231ps and vbroadcastf32x8 for breakfast. You are proficient in modern C and experienced with SIMD, hardware offloading and safety.

Please contact me if you're interested or have further questions.

lebubule··on Polymorphic Types in C [pdf]
Yes, please better support for arrays, mainly multidimensional. Fortran is good for that. With good arrays I think that strings comes naturally.
lebubule··on Std: Clamp generates less efficient assembly than std:min(max,std:max(min,v))
Yes, I arrived at the same conclusion.

The various code snippets in the article don't compute the same "function". The order between the min() and max() matters even when done "by hand". This is apparent when min is greater than max as the results differ in the choice of the boundaries.

Funny that for such simple functions the discussion can become quickly so difficult/interesting.

Some toying around with the various implementations in C [1]:

lebubule··on Can a Human See a Single Photon? (1996)
Recent experiments have put the claim to test

Overview https://www.nature.com/articles/nature.2016.20282

The actual work https://www.nature.com/articles/ncomms12172

> Here we report that humans can detect a single-photon incident on the cornea with a probability significantly above chance.

lebubule··on A thin gold layer could be the secret to glasses that don't fog
Yes it could. But, it requires absorbing radiation further down in the infrared and power is an issue to consider! What radiates more your ears or a sun?

Titania has higher refractive index. It helps improve slightly the performance.

Work and studies of metal films and thin films as well as their fabrication has been going on for more than a century. Basically since electromagnetism is popular.

Fabrication tools for thin films have improved a lot over the past decades though. We can now fabricate exotic structured matter at the nanoscale that doesn't respond as the bulk counterpart.

Yes, of course there is still much work left for full scale industrializing but nothing insurmountable in view.

While I would agree with you that media often phrase thing the mentioned way, I would prefer here to state that X implies Y. The question is more whether it will be picked up more widely at industry scale.

We took great care to show real-world applicability of our work.

The coating is just a few nanometers thin. Price wouldn't be the main issue there.

Hi there,

I am a co-author of the mentioned work and very surprised (but pleased) to see it here.

I think that this is a good overview!

On the material part the sweet spot is the transition from assemblies of particles to forming a continuous path (film).

For the application you indeed need sunlight. The sun is a strong radiation source!

Putting your face under a light bulb might cause other issues.

Glasses is here the most accessible example to illustrate the work from the research to the application. I think we can get creative about other use cases.

lebubule··on Ur-Fascism By Umberto Eco (1995) [pdf]
"even though I am much concerned about the various Nazi-like movements that have arisen here and there in Europe, including Russia, I do not think that Nazism, in its original form, is about to reappear as a nationwide movement."

"Fascist governments are condemned to lose wars because they are constitutionally incapable of objectively evaluating the force of the enemy."

"The Ur-Fascist hero is impatient to die. In his impatience, he more frequently sends other people to death."
