Getting Better at Reading Academic Papers: a Brief Guide for Beginners (Part 2)

Reading time3 min
Views2.1K
«Nothing makes you feel stupid quite like reading a scientific journal article» — writes the TV presenter and molecular biologist Adam Ruben. In a way, he's right — many of us get lost in the often confusing language of peer-reviewed papers. But the situation does not have to be hopeless. A bit of effort on the readers' part can go a long way. We looked at the techniques actual scientists use to navigate academic content. And compiled them into this two-part guide (Part 1: Getting Better at Understanding Academic Papers).

The book of Ecclesiastes


In 1998, a completely unique, for its time, application was developed that allows you to reduce the process of developing an abstract board game (or puzzle) to a small text description language, vaguely reminiscent of Lisp. This project was called Zillions of Games. It created a furor among fans of board games. Currently, over 2,000 applications have been created using this technology.

Are you ready to get started with 3D printing but just aren’t sure about what filament you’re using? You’re definitely not alone because with the multitude of different filaments out there it can really get complicated. You find yourself overwhelmed while you’re trying to research because it seems like everyone has a different idea of what the best option is and it can easily seem like you’re being pulled in different directions. So, let’s take a closer look at how you can make the right decision.

Geolocation and geoposition — mega-tool

Introduction


Today, geolocation and geo-positioning have turned into a state that we did not dream about 60 years ago, during the first thoughts about creating an Internet network.

This article was prepared thanks to the IPGeolocation.io

Cartography has turned into a miracle — from insanely large sheets of paper to what fits in the palm of your hand.

Today, maps are used not only to search for a cultural center in Paris, but to be able to find everything:

  • nearest hotel
  • pharmacy or hospital
  • grocery store
  • university or school
  • Pink Concert venue in San Francisco

The transformation of technology will not stop there. It will be better and more accurate than ever.

Evolution in time


Let's see how the evolution of geolocation began. The journey of this phenomenon begins in ancient times.

Modern Presentation Format?

Reading time7 min
Views3.4K

Nowadays, when VR helmets have become part of our reality and Tesla cars fly in space, you can use all the power of browser engines to create truly interactive, cross-platform and stylish presentations, rather than make a set of PPTX pages or, even worse, a PDF document in "illustrative material for explanatory and calculation report" style.



Since 2015, I have been trying to find the optimal presentation format for myself (apart from graduation projects). And now I think I have almost succeeded. It all started with PowerPoint, and ended with web frameworks based on JavaScript.


There are several JavaScript engines which can be used to create cool presentations: Marp, Reveal, landslide, hacker-slides, slidify and others. In some engines, you can use Markdown, some are embedded in an IDE, and some have their own editors. I have tried the first two engines.


As a demonstration, slide examples and video are available.

Tech Insights: Are LED filament-lamps so good?

Saluting my LED lamp fans!

Today we will talk about the palpitating and extremely popular subject in recent years — filament LED (Light-Emitted Diode) lamps. Numerous articles have been published here on Habr (1, 2, 3) and on the web, but none of them tells us a word about in-depth analysis of the lamps (what is actually inside) and comparison of their temperature characteristics. Therefore, especially for you — my dear LED-lovers — I conducted a detailed analysis of such lamps from different manufacturers, including temperature measurement of LEDs themselves.

Afterwards we will try to answer the question: are filament lamps as good as marketers present them to us?

Disclaimer: this is my very first attempt to translate and adopt an article from Habr into English, so I will ask you to give a fruitful feedback and correct some mistake if any present.
Shock, thrill and scandals!

Drawing of lightbulb in protected circle


At Microsoft, we’re investing in helping our customers as they move to the cloud. We see an opportunity to help support companies in this changing environment by bringing our security, privacy, compliance and intellectual property assets and expertise to bear in order to help them be more successful. We’re excited to now take an additional step that expands innovation protections.

Today, we are pleased to announce the expansion of the Microsoft Azure IP Advantage program to include new benefits for Azure IoT innovators and startups. We first announced Azure IP Advantage in February 2017, to provide comprehensive protection against intellectual property (IP) risks for our cloud customers. A trend we saw at the time – and one that continues today – is a growing risk to cloud innovation from patent lawsuits. Last year, we joined the Open Invention Network (OIN) and the License on Transfer (LOT) Network to help address patent assertion risk for our customers and partners.

How to Fail Those Students Who Rely on ChatGPT

We at Verilog Meetup constructed an exam/interview problem that has an interesting property: if a student tries to figure out a solution by thinking by himself, he usually succeeds; however if he dumps the problem on ChatGPT, the solution fails (does not pass the automated test), and the student goes into a death spiral of futility, kicking ChatGPT to get the solution right.

There is nothing weird about the problem, we do this in the industry all the time:

Exploring VALID/READY protocol, pipelines and experimenting with flow control using an HDL training tool

Understanding valid/ready protocol is extremely important for every microarchitect.

Valid/ready is one of the main protocols used to organise flow-control inside a logic block as well as on inter-block (SoC) level.

In the last lesson, we explored FIFO buffer using hdlgadgets - human-in-the-loop HDL training tool.

This time we will take two FIFO buffers (which form a pipeline with valid/ready handshakes) and will experiment with it by changing flow-control logic of the pipeline.

We will show that valid/ready is not only a mechanism for transferring data from one FIFO queue to another, but also a method for organizing various kinds of logical functionality between queues.

If you have not worked with valid/ready protocol before, you will be surprised how easy it is to achieve desired functionality of the design by simply writing couple of lines of Verilog code in the handshaking logic block between two FIFOs.

«Promising Public Transportation for Large and Medium-Sized Cities» — the main idea in a brief summary

Translation provided by ChatGPT, link to the original article.

I recently published a series of articles titled 'As Cheap as a Bus, as Convenient as a Taxi...':

Link to Part 1: «Preliminary Analysis» (ру / eng )
Link to Part 2: «Experiments on a Torus» (ру / eng )
Link to Part 3: «Practically Significant Solutions» (ру / eng )

dedicated to making public transportation in large cities completely seamless, without the need for transfers. In the last article of the series, I extensively described a microbus movement scheme that allows them to operate almost like taxis while accommodating 5-10 passengers at once. Such a transportation system would enable city residents to travel from any intersection to another without any transfers, comparable in time to a personal car journey, and at a cost similar to a regular city bus ticket. However, the feedback from readers indicated that I chose an extremely ineffective way to convey the information, resulting in a failure to effectively communicate the essence of the matter.

I must admit that the previous three articles were written in a way that allowed readers to apply the acquired knowledge in practice or continue the research I started on their own. Unfortunately, my desire to 'teach' resulted in nearly 100 pages of complex mathematical text, which is clearly excessive for readers who simply wanted to familiarize themselves with the idea. Here, I will attempt to rectify this mistake and briefly, yet simply, explain the bus taxi technology.
