problem with mplayer diacritics

Though not as popular as it used to be, mplayer is very versatile and I like it.
On a certain movie the .srt subtitle was displaying funny characters.
First I added all needed languages in Language Settings and then went into ~/.mplayer/config where I commented the iso8859-1 line and added utf-8. All worked well.

#subcp = iso8859-1

Blockchain Scalability

Imagine Gmail running on a single computer and processing the emails for everyone on the globe. How many total users do you think it could handle? Probably a few thousands. But the globe has billions of people.

The same applies to blockchains. We are in the stage where an Ethereum node has to mirror the whole database of past transactions and to process every single future transaction. It is obvious that mass adoption is not possible with such offer.

Databases had the same problem and software architects came with sharding, a horizontal partition of data where each shard is held on a separate database server instance, to spread load. The same solution can be applied for blockchains. Zilliqa already has a working testnet and Ethereum is implementing one.

QuarkChain is a new blockchain that utilizes sharding to create a highly scalable and secure platform to handle up to one million transactions per second. QuarkChain supports smart contracts with the use of Ethereum Virtual Machine - EVM.

With an experienced and strong team Quarkchain is an ambitious project that enters the high scalability blockchain arena. May the best ideas prevail!

Web3 Communications Layer

Gmail, Skype, Google Docs, Trello, Telegram - all these products are free, easy to use and overall they seem very convenient.

Now I stop and think why? Why would someone give you access to their infrastructure for free? Why would they constantly pay software engineers to keep their products updated? Why they constantly implement top class features and improvements? What are they getting back that is so valuable to compensate for all their costs? The answer is very short and very simple: POWER.

But I have the right to say NO, I have to right to not be a part of their system. That's why the mission of Mainframe is important to me.

In terms of value, I believe that most of the decentralized projects are going to need sooner or later a secure communication protocol, so there is a high chance that Mainframe will have a good adoption rate.

A New Generation of Blockchain: SEELE

Bitcoin is considered the v1 of Blockchains. Then Ethereum came with smart contracts and we advanced to v2. The v3 with improved scalability and advanced governance is still under development and it is represented by projects like Cardano, Lisk and Zilliqa.

But you can't stop technology from evolving, so we already have our first v4 under development: SEELE. It comes with Neural Consensus algorithm, Heterogeneous Forest, Computing sharing between on-chain and off-chain and it should be able to achieve millions of transactions per second.

Seele is getting faster as the number of nodes grows. The algorithm is inspired from the ideas of biological neural networks. Seele does not use miners, so no electricity or hardware working in vain.

Just like Ethereum and EOS, Seele uses a Virtual Machine to execute smart contracts. The Seele VM is more powerful and more customizable. Seele Blockchain is suitable for: IoT, social applications, blockchain games, E-government, Fintech, Healthcare.

TomoCoin approach to Ethereum scalability

Ethereum is a decentralized blockchain where smart contracts run exactly as programmed without any chance of fraud, censorship or third-party interference. Today, the main issue with Ethereum is the lack of scaling capability.

TomoCoin is addressing this problem in three steps.

1. TomoChain

Tomochain is planning to support horizontal scaling via adding more second layer blockchains with good performance integrated with Ethereum for backup and atomic cross-chain transfer.  

2. TomoApp

With TomoApp you can mine coins by making valuable content contributions. TomoApp offers privacy and zero fee micro payments.  

3. TomoWallet

TomoWallet is focused on security and user experience. Atomic exchanges will have with zero fee and fast confirmation. You can use TomoWallet to send and receive multiple tokens and secure messages.

Goto official website for more details.

Schedule ETH transactions with Chronobot

Sometimes you need to make an Ethereum payment transfer at a specific time that may not be very convenient to you(middle of the night, airplane flight, etc). With Ethereum Chronobot, you can submit signed transactions to be executed lately at the time you choose. In the case of ICOs this might be very handy, because you can prepare everything and schedule the payment exactly when the ICO starts so you minimize the chances of missing it.

Chronobot will broadcast your transactions to multiple nodes so miners can pick it up very fast. There is no need to keep your internet connection up or wallet open, once you have submitted to Chronobot, everything will be done automatically.

What is Beenest and The Bee Token?

Beenest is a home sharing platform for hosts to advertise their homes and for guests to search accommodations.Yes, it sounds like Airbnb, but it's completely decentralized.

The Bee Token is the cryptocurrency that fuels the Beenest platform and the Bee Protocols

Bee Protocol has three important parts:

1. Payment Protocol - send and receive tokens held until fulfillment of service
2. Arbitration Protocol - solve disputes through trustless voting
3. Reputation Protocol - manage reputation scores for all P2P entities

Beenest uses Bee Protocol, but Bee Protocol is flexible and can be used on much more purposes and applications.

Check for more details.
