Mind traps: how scientists fool themselves

Reading time5 min

Even the most honest of scientists are regularly misled by their cognitive biases. They often go to great lengths to find proof for whatever seems logical, while dismissing evidence to the contrary.

Yet this issue is rarely discussed — because it remains an embarrassing subject.

Swiss scientists develop ultra-fast resin 3D-printing technique

Scientists at the Laboratory of Applied Photonics Devices from the Swiss Federal Institute of Technology in Lausanne (EPFL) are developing a new high-performance 3D-printing technique. Their patent-pending volumetric printing technology features rotational exposure of photopolymer resins to radiation resulting in light-shaping. Another peculiarity is that the part is printed in a single step, not layer-by-layer.

The technology itself seems to be of US origin. At the beginning of the previous year, a team of scientists from Berkeley and Lawrence Livermore National Laboratory (LLNL) demonstrated Computed Axial Lithography (CAL), a 3D-printing method based on LLNL’s previous researches on resin 3D-printing technique that features holographic patterning of light fields. The models were initially formed by laser beam crossing, which is very complex and expensive. Therefore, it’s been decided to alter the technology in favor of rotational exposure of photopolymer resins.

PIM software or product information management represents a solution for e-commerce businesses where they can consolidate all of their product information into a single place.

PIM software implementations generally provide support for challenges related to:

  • Handling multi-language data
  • Multiple geographic locations
  • Modification of product information within a product catalog
  • Managing product information to be scattered throughout business processes

While PIM software handles most of the e-commerce challenges, it also works as an efficient tool that powers – omnichannel experience, product expansion to new markets, increased conversion rates, superior customer experiences, decreasing the number of product returns, and faster time-to-market.

In general, product information management or PIM software is a set of business applications focused on managing product information for use across an e-commerce business from the supply chain to managing customers, product presentation, data handling, and catalog management.

In life we often face the challenge of choosing the right colors. This happens when we need to choose clothes suitable for each other, shoes suitable for clothes, choose different wallpapers for the children's room, makeup, choose colors for our site and much more. The process of selecting several colors that combine with each other is called the construction of a color palette (gamut).

In colouristics there are several methods for constructing a color palette (color gamma) based on the arrangement of colors relative to each other in the color circle and, usually, having the same brightness. Harmonious perception of which is not sufficiently substantiated from the physical point of view.

The wave method of building color palette based on the relationship of color and acoustic waves, and also the concept of consonance (harmony) in music theory. Below is a more detailed description of the method.

This site allows you to choose the most harmonious combination of colors for your site, clothing, interior, etc.

MUROM


Hi, my name is Michael Kapelko. I'm a professional software developer. I'm fond of developing games and teaching folks to program.


Preface


Autumn 2019 was the third time I participated as one of the teachers in the course to teach 10-15-year-old folks to program. The course took place from mid. September to mid. December. Each Saturday, we were studying from 10 AM to 12 PM. More details about the structure of each class and the game itself can be found in the 2018 article.


I have the following goals for conducting such courses:


  • create a convenient tool to allow the creation of simple games, the tool interested folks of 10 years old or older can master;
  • create a program to teach programming, the program interested folks of 10 years old or older can use themselves to create simple games.

Hypercube. How we gave developers test devices without losing any

Reading time11 min
Views5.1K
You can’t properly test and debug mobile apps without test devices, which there should be plenty of considering how the same code may behave differently on different models. So how do we keep track of these devices? How do we quickly provide developers and testers with the smartphones they need, configured the way they need, and without much red tape?

I’m Alexey Lavrenuke. Over the years, I’ve worn many hats: one of the authors behind Yandex.Tank, a speaker on load testing, and the guy who calculated energy consumption by mobile phones. Now I’m a Yandex.Rover developer on the self-driving car team.

After the phones and before Yandex.Rover, there was Hypercube.

A few years ago, the head of mobile development popped in to the load testing department and mentioned a problem they were having with test devices: phones had a tendency to inexplicably migrate from one desk to another. Picking the right device and then finding it had become a challenge. We already experienced working with mobile devices from building a digital ammeter to calculate energy consumption, so we decided to help our coworkers out and quickly rig up a handy contraption. We figured the whole thing wouldn’t take more than three months. Oh how wrong we were. Let me tell you what we were really in for.

Master’s degrees are really useful. Postgrad education allows BA holders to put their new-found skills into practice, and secure great jobs further down the road. But students often need help assessing this choice, particularly if they majored in uncommon subjects — like photonics.

To set the record straight, we talked to the people behind, and the graduates of our MA programs in photonics and optical computing. In this article you’ll learn about part-time work available for photonics students, graduates’ job-hunting prospects, and the academic career options that open up.

Making a demo for NES — HEOHdemo

Reading time26 min
Views5.8K
There is a lengthy history of computer arts festivals, also known as demo parties, held in Russia over the last quarter century. For decades, once in a while people from all over the country gather together to compete in their ingenuity at getting what was once deemed impossible out of the old or new computer hardware and mere bytes of code. A few leading annual events has been established in the early years. One of them, creatively named CAFe (an acronym for Computer Art FEstival), was held in Kazan from 1999 to 2003. It went under the radar since, making the way for the everlasting Chaos Constructions (1999 — now) and DiHalt (2005 — now). After so long hiatus, the last year CAFe made a loud comeback, returning in full glory — at least by the number of prods released, if not in the scale of the event itself. Presentation of the compo entries went far into the night, with the last demos being shown at 6 AM to the popping eyes of the few hardy ones. There was my demo, too, and this is the story of its making.
