Rocket.Chat is Switching to Matrix to Enable Cross-App Messaging
|
||||
======
|
||||
Rocket.Chat is embracing the Matrix protocol to enable decentralized communication for the platform. That’s a huge change, isn’t it?
|
||||
|
||||
![rocket chat matrix][1]
|
||||
|
||||
Rocket.Chat is an excellent open-source messaging (collaboration) platform.
|
||||
|
||||
In fact, it is one of the [best open-source Slack alternatives][2] available. We use it as well for internal communication.
|
||||
|
||||
Rocket.Chat is also making good progress compared to some of its open-source competitors. For instance, they [teamed up with Nextcloud to provide an alternative to Office 365][3].
|
||||
|
||||
And recently announced a switch to Matrix protocol to introduce federation capabilities that allow its users to communicate with users on other platforms. In other words, [Rocket.Chat][4] will be utilizing a decentralized network for communication with the Matrix integration.
|
||||
|
||||
As a Rocket.Chat user; you can talk to users on any other app using the Matrix protocol.
|
||||
|
||||
### Rocket.Chat is Switching to a Decentralized Protocol to Enhance Collaboration
|
||||
|
||||
![][5]
|
||||
|
||||
Matrix protocol is a fantastic choice to enable an interoperable federation. Now, with Rocket.Chat onboard; the decentralized network should be stronger than ever.
|
||||
|
||||
Not to forget, we already have [Element][6], and [Gitter][7], as some of the platforms that already utilize Matrix. So, Rocket.Chat joining the network sounds exciting!
|
||||
|
||||
The [official announcement][8] further explains the collaboration:
|
||||
|
||||
> The Rocket.Chat adoption of Matrix makes it simple for organizations to easily connect with external parties, whether they’re using Rocket.Chat or any other Matrix compatible platform. This initiative is another step forward on Rocket.Chat’s journey to let every conversation flow without compromise and enable full interoperability with its ecosystem.
|
||||
|
||||
The new change with the Matrix network is already available in the latest [alpha release for Rocket.Chat 4.7.0][9]. Unless you want to experiment with it, you should wait for the stable release to introduce the Matrix network support.
|
||||
|
||||
**Aron Ogle** (*Core Developer at Rocket.Chat*) has put together a [guide][10] and a video to help you out if you want to explore the technical details of Rocket.Chat integration with the Matrix. Here’s the video for it:
|
||||
|
||||
![Setting up Rocket Chat to talk with Matrix][11]
|
||||
|
||||
### Is This a Good Move?
|
||||
|
||||
While decentralized tech hasn’t taken the internet by storm, it is promising and makes more sense with its reliability and decentralized capabilities. Matrix protocol has been getting all the praise for a couple of years now, and it seems to be heading in the right direction.
|
||||
|
||||
As of now, most of the big platforms rely on centralized infrastructure to make things work.
|
||||
|
||||
And, with the current implementations, cross-communication is not possible with most of the chat applications.
|
||||
|
||||
So, Rocket.Chat will be making a difference by offering cross-app interactions, like the ability to chat with an Element user on **matrix.org,** as shown in the image above.
|
||||
|
||||
Rocket.Chat entering the scene with Matrix protocol could open up the potential for its competitors or other services to give a second thought to solutions like Matrix protocol.

Google Makes Data Centre Scale Encryption Open Source
|
||||
======
|
||||
![google-ranking-factors][1]
|
||||
|
||||
Google has made open source an encryption scheme it developed to protect traffic between its data centres. PSP, which stands for PSP Security Protocol, was created to relieve Google’s processors of the growing burden of software-based encryption, according to the company. PSP has been hailed as a success in the company’s own environment, and the company has stated that it is “making PSP open source to encourage broader adoption by the community and hardware implementation by additional NIC [network interface card] vendors.” PSP offloads encryption to NICs, which was previously possible with existing encryption schemes, but not at the scale or with the traffic coverage required by Google.
|
||||
|
||||
“At Google’s scale,” the company wrote when announcing its decision, “the cryptographic offload must support millions of live transmission control protocol (TCP) connections and sustain 100,000 new connections per second at peak.”
|
||||
|
||||
Existing security protocols, according to Google Cloud’s Amin Vahdat and Soheil Hassas Yeganeh, had flaws. “While TLS meets our security requirements, it is not an offload-friendly solution because of the tight coupling between the connection state in the kernel and the offload state in hardware. TLS also does not support non-TCP transport protocols, such as UDP”, they stated.
|
||||
|
||||
However, the IPSec protocol cannot be offloaded to hardware at the required scale. “IPSec … cannot economically support our scale partly because they store the full encryption state in an associative hardware table with modest update rates,” the post explains.
|
||||
|
||||
Google added a custom header and trailer to standard User Datagram Protocol (UDP) encapsulation to create PSP. PSP is currently implemented in three ways: one for Google’s Andromeda Linux virtualisation kernel, one for its Snap networking system, and an application-layer version, SoftPSP, created so Google Cloud customers could use PSP on computers with traditional NICs.

Spotify Introduces an Open-Source Tool to Fix a Big Problem for Modern Musicians
|
||||
======
|
||||
Spotify’s new open-source tool helps you convert audio to MIDI version. Explore why it is a big deal for modern musicians.
|
||||
|
||||
![spotify][1]
|
||||
|
||||
Spotify is a leading music streaming platform with several open-source projects.
|
||||
|
||||
While most of the projects/tools are built for niche users, they have finally introduced something that seems enticing to all the modern musicians involved with digital music production.
|
||||
|
||||
‘Basic Pitch’ is a new free and open-source tool by Spotify that lets you convert any audio file to its MIDI (Musical Instrument Digital Interface) version.
|
||||
|
||||
In case you did not know, with MIDI notes, you can easily tweak what’s being played and analyze more to help you in digital music production.
|
||||
|
||||
### Basic Pitch: Making Things Easier
|
||||
|
||||
With Basic Pitch, one can easily have MIDI notes of an audio file they have always wanted, and with better accuracy.
|
||||
|
||||
![spotify basic pitch][2]
|
||||
|
||||
Spotify explains that it is better than existing note-detection systems by offering some advantages that include:
|
||||
|
||||
> **Polyphonic + instrument-agnostic:** Unlike most other note-detection algorithms, Basic Pitch can track multiple notes at a time and across various instruments, including piano, guitar, and ocarina. Many systems limit users to only monophonic output (one note at a time, like a single vocal melody), or are built for only one kind of instrument.
|
||||
|
||||
> **Pitch bend detection:** Instruments, like guitar or the human voice, allow for more expressiveness through pitch-bending: vibrato, glissando, bends, slides, etc. However, this valuable information is often lost when turning audio into MIDI. Basic Pitch supports this right out of the box.
|
||||
|
||||
> **Speed:** Basic Pitch is light on resources, and is able to run faster than real time on most modern computers ([Bittner et al. 2022][3]).
|
||||
|
||||
Basic Pitch uses a machine learning model that turns various instrumental performances into MIDI. The audio file may also contain your voice, but it should still be able to convert the instrument to its MIDI version.
|
||||
|
||||
![Basic Pitch demo: Convert audio into MIDI using ML][4]
|
||||
|
||||
I tried converting an MP3 karaoke file with a single instrument to get the MIDI notes, and it seemed to work pretty well.
|
||||
|
||||
The tool also lets you process more than one audio file at a time and offers a few parameter controls that include note segmentation, confidence threshold, minimum/maximum pitch, and note length.
|
||||
|
||||
### Made for Creators and Researchers
|
||||
|
||||
Spotify mentions that it targets the creators primarily, but they are also interested to learn how machine learning researchers build upon it and help develop better solutions using the [open-source project on GitHub][5].
|
||||
|
||||
As a creator/musician, you can access the open-source tool on its [official website][6] for a demo. The parameters can be adjusted using the website, and you can also download the MIDI file from there.
|
||||
|
||||
[Basic Pitch][7]
|
||||
|
||||
![spotify basic pitch][8]
|
||||
|
||||
It is also available via [PyPI][9] to install and use via the command-line interface on Linux, Windows, and macOS.
|
||||
|
||||
You can explore its [GitHub page][10] to know more about its usage/commands.
|
||||
|
||||
If you are curious, the [official announcement post][11] provides more technical comparisons and explanations regarding the development of the tool.

Cloud Storage Service Internxt Has a Photos Feature as a Google Photos Alternative
|
||||
======
|
||||
Internxt is already an interesting cloud storage service. It also has a Photos feature that can be a replacement to Google Photos for some.
|
||||
|
||||
![internxt photos][1]
|
||||
|
||||
Internxt is an open-source encrypted cloud service with a native Linux client. Our [older article][2] explaining its cloud storage service can be an interesting read if you did not know about it.
|
||||
|
||||
Initially, we focused on their cloud storage offering. And, it seems like we missed out on another product “Photos” that was unveiled by them last month in a tweet.
|
||||
|
||||
[Internxt Photos][3] pitches itself as an open-source Google Photo alternative with privacy and security in mind.
|
||||
|
||||

|
||||
|
||||
### Internxt Photos with Zero-Knowledge Encryption
|
||||
|
||||
![][4]
|
||||
|
||||
Internxt Photos claims that it puts privacy and security at its core compared to some competitors in the industry.
|
||||
|
||||
While respecting user privacy, they also try to offer the basic features that help you easily organize the photos you upload to the service.
|
||||
|
||||
Note that the Photos service is included with the cloud storage subscription. Unlike Google’s offering, there are no separate pricing plans for just storing the Photos.
|
||||
|
||||
Likewise, you need to rely on the same Internxt app to access your Photo gallery.
|
||||
|
||||
You should not have anything to worry about considering the Internxt app is available on the Google Play Store, and the App Store as well.
|
||||
|
||||
The photos you upload to the gallery get synced across multiple devices. So, even if you do not have access to one of your devices, it should not be a problem.
|
||||
|
||||
![][5]
|
||||
|
||||
The look of the photo gallery seems inspired by Apple’s Photos app, but that’s a good approach for simplicity and usability. The Photos also provide you the ability to share photos with your friends and family using a link. You can also customize the link to tweak the open limit to control access to your shared links.
|
||||
|
||||
Considering it as an open-source encrypted alternative with a primary cloud storage offering to mainstream Photo storage services, does this sound like something interesting to you?
|
||||
|
||||
You can get started using our link to the product page to explore more about it and get started. The [GitHub page][6] can also be useful if you’re curious.
