We're in UltraHD Morty! How to watch any movie in 4K

Reading time3 min
Views14K
You’ve probably heard about Yandex’s DeepHD technology they once used to improve the quality of old Soviet cartoons. Unfortunately, it’s not public yet, and we, regular programmers, don’t have the dedication to write our own solution. But I personally really wanted to watch Rick and Morty on my 2880x1880 Retina display. And I was deeply disappointed, as even 1080p video (the highest available for this series) looks really blurry on a Retina display! Don’t get me wrong, 1080p is often good enough, but Retina is designed in such a way that an animation with its pronounced outlines in 1080p looks awfully blurry, like 480p on a FullHD monitor.

I decided I want to see Rick and Morty in 4K, even though I can’t write neural networks. And, amazingly, I found a solution. You don’t even need to write any code: all you need is around 100GB of free space and a bit of patience. The result is a sharp 4K image that looks better than any interpolation.

You Do Not Need Blockchain: Eight Well-Known Use Cases And Why They Do Not Work

Reading time9 min

People are resorting to blockchain for all kinds of reasons these days. Ever since I started doing smart contract security audits in mid-2017, I’ve seen it all. A special category of cases is ‘blockchain use’ that seems logical and beneficial, but actually contains a problem that then spreads from one startup to another. I am going to give some examples of such problems and ineffective solutions so that you (developer/customer/investor) know what to do when somebody offers you to use blockchain this way.


Disclaimers


  • The described use cases and problems occur at the initial stage. I am not saying these problems are impossible to solve. However, it is important to understand which solutions system creators offer for particular problems.
  • Even though the term ‘blockchain use’ looks strange and I am not sure that blockchain can be used for anything other than money (Bitcoin), I am going to use it without quotes.

1. Supply chain management


Let’s say you ordered some goods, and a carrier guarantees to maintain certain transportation conditions, such as keeping your goods cold. A proposed solution is to install a sensor in a truck that will monitor fridge temperature and regularly transmit the data to the blockchain. This way, you can make sure that the promised conditions are met along the entire route.

At the same time, one million clients have joined and used Monzo’s services (Monzo). Such tendency establishes substantial competition for all players including high-street banks in the payments market.

In consequences, the main object of the paper is identification the advantages of digital bank and illumination capabilities to deploy analogous mobile bank in Kazakhstani real financial sector.

A version how people transported megaliths in Stonehenge.

They started their work in summer.

They prepared road for transportation. They needed a clean and glade road without stones and other irregularities. (No.4 on picture)
Perhaps they cut the topsoil and covered the road with clay. (No.3 on the picture)
On each side they made curbs ( 5-10 cm). (No.2 on the picture)
They used clay because they wanted to hold water inside the road.
In autumn rains filled road with water. It looked like a big puddle. (No.5 on the picture)

In winter road froze. Then they got a smooth ice skating rink slightly wider than a megalith.

Megaliths (No.11) were transported in winter.

Mechanism and vehicles for transportation were prepared in summer.

Mechanism consisted of three parts.

Hi everyone!

Winter has arrived, and so I had to check the thermal insulation of my out of town residence dacha. And it just turned out a famous Chinese marketplace started to sell cheap thermal camera modules. So I decided to DIY it up and build a rather exotic and useful thing — a heat visor for the home. Why not? Especially since I had a Raspberry Pi lying around anyway… The result is down below.

Is Haskell really the language of geniuses and academia?

Reading time9 min

I once had a discussion with a founder of an Israeli startup developing a GPU-based database with a focus on speed. The work stack included Haskell and C++, among others, and the founder was complaining about how hard it is to find competent programmers. Which was part of the reason he came to Moscow.

I carefully asked if they considered using something more popular and new. And even though the answer was rather polite and well-supported with arguments, it still sounded like “Come on, don’t even bring up these toys”.

Until then, all I heard about Haskell could be summarized as “be VERY careful in dealing with it”. To get to know Haskell programmers better, I came to a topical Telegram chat with some questions. I was quite afraid at first, and, as it turned out, I was right.

Haskell doesn’t lend itself to popular explanation, and people seemingly don’t even try. If the topic is ever brought up, it’s only talked about in full depth and as objectively as possible. Someone wrote to me: “One of the defining features of both Haskell itself and its community is that they didn’t try to achieve any kind of mainstream recognition. Instead, they focused on building a logical, principal way of solving real problems over trying to appease the widest audience possible”

Nevertheless, a couple of people did tell me about their experiences, which are shown below.

Once I put on true wireless headphones and all the cables after that (even if it's a flexible headband on a “wireless” headset), became annoying. So I’ve tried a lot of AirPods-like earbuds in order to find the best ones. In 2018 aside from the AirPods themselves I tried: Jabra Elite 65+, Samsung IconX 2018 and Sony WF-1000X. The result was a neat table with all the objective data. Everything else — my personal opinion — let's discuss in the comments.

When you are sitting in your comfy chair in your cool modern office, anything distracting you from your favorite routine is really annoying. Some may call it a sign of sloth, but in fact, it relates to optimization of workflows. Our computers and smartphones provide us with many opportunities to do a lot without leaving our place. Software as such cares about our control over the physical world by just clicking and tapping. Indeed, the digitization advances: what people have had to do with their muscles for centuries in the past, could be done with either a voice command or a text message today thanks to numerous remotely controlled gizmos. And the IoT plays a crucial role in all this for a reason.

The very paradigm of automation where IoT solutions play a key role is based on a presumption that machines can act in both autonomous and intelligent manners. And what enables them doing so is a capability of handling tremendous flows of collected data.

The collectible data includes those various signals that both animate and inanimate object can send to the IoT systems. Hence, the objects should have some highly specific signal-generating devices to share information within the IoT.

I’m going to hazard a guess and say that everyone whose friends or family have ever flown on a plane, have used Flightradar24 — a free and convenient service for tracking flights in real time.



But, if my friends are any indication, very few people know that the service is community-driven and is supported by a group of enthusiasts gathering and sending data. Even fewer people know that anyone can join the project — including you.

Let’s see how Flightradar and similar other services works.
