Fruit Flies, Fighter Jets Use Similar Evasive Tactics When Attacked

Fruit Flies, Fighter Jets Use Similar Evasive Tactics When Attacked

When startled by predators, tiny fruit flies respond like fighter jets – employing screaming-fast banked turns to evade attacks. Researchers at the University of Washington used an array of high-speed video cameras operating at 7,500 frames a second to capture the wing and body motion of flies after they encountered a looming image of an approaching predator (abstract). ‘We discovered that fruit flies alter course in less than one one-hundredth of a second, 50 times faster than we blink our eyes, and which is faster than we ever imagined.’ In the midst of a banked turn, the flies can roll on their sides 90 degrees or more, almost flying upside down at times, said Florian Muijres, a UW postdoctoral researcher and lead author of the paper. ‘These flies normally flap their wings 200 times a second and, in almost a single wing beat, the animal can reorient its body to generate a force away from the threatening stimulus and then continues to accelerate,’ he said.

First there was the anternet, and now this?  It almost sounds like humans a giant insects…

Six Ways to Make Your Production Logs More Useful

Six Ways to Make Your Production Logs More Useful

  1. Log structured data in a readable format
  2. Add a dash of color
  3. Logs let your app communicate with you and your team
  4. Seriously though, don’t put exception stack traces in your logs!
  5. Log URLs for easy access to more context
  6. Add emotional context to your logs

Most of these are somewhat expected, but I emotional context in logs was definitely new to me. I wonder why I’ve never even thought of this.

Management by wandering around

Management by wandering around

The term management by wandering around (MBWA), also management by walking around, refers to a style of business management which involves managers wandering around, in an unstructured manner, through the workplace(s), at random, to check with employees, or equipment, about the status of ongoing work. The emphasis is on the word wandering as an impromptu movement within a workplace, rather than a plan where employees expect a visit from managers at more systematic, pre-approved or scheduled times. The expected benefit is that a manager, by random sampling of events or employee discussions, is more likely to facilitate improvements to the morale, sense of organisational purpose, productivity and total quality management of the organization, as compared to remaining in a specific office area and waiting for employees, or the delivery of status reports, to arrive there, as events warrant in the workplace.

Who knew that was a thing?

С Днем Космонавтики, друзья!

Чтобы все знали, папа у меня космонавт. Ну почти. Он в космос не летал, но на космонавта учился! И не просто на космонавта, а на бортстрелка-радиста. Тогда готовились станции “Алмаз” для боевых целей с экипажем из шести человек и пушкой на борту. Чтобы чужие спутники сбивать.

И вот папа часами крутился на центрифуге, стрелял подвешенный вниз головой, с качающейся платформы и готовился к космическим войнам. Но американцы струсили и договорились, что космических войн не будет.
