Solid: new web startup by Tim Berners-Lee

The Inventor of the World Wide Web Plans to Start a New Internet to Take on Google and Facebook

"Tim Berners-Lee, the inventor of the World Wide Web, is launching a startup that seeks to rival Facebook, Amazon and Google.

The technology legend’s latest project, Inrupt, is a company that builds off of Berners-Lee’s open source platform Solid. Solid allows users to choose where their data is stored and what people are allowed to have access to what information.

In an exclusive interview with Fast Company, Berners-Lee joked that the intent behind Inrupt is “world domination."

One Small Step for the Web… – Tim Berners-Lee – Medium


"Solid changes the current model where users have to hand over personal data to digital giants in exchange for perceived value. As we’ve all discovered, this hasn’t been in our best interests. Solid is how we evolve the web in order to restore balance — by giving every one of us complete control over data, personal or not, in a revolutionary way."

"Re-decentralizing the web"

GitHub - solid/solid: Solid - Re-decentralizing the web (project directory)

"Solid (derived from "social linked data") is a proposed set of conventions and tools for building decentralized Web applications based on Linked Data principles. Solid is modular and extensible. It relies as much as possible on existing W3C standards and protocols."


Exclusive: Tim Berners-Lee tells us his radical new plan to upend the WWW

"The difference here is that, on Solid, all the information is under his control. Every bit of data he creates or adds on Solid exists within a Solid pod–which is an acronym for personal online data store. These pods are what give Solid users control over their applications and information on the web. Anyone using the platform will get a Solid identity and Solid pod. This is how people, Berners-Lee says, will take back the power of the web from corporations."

ChromeOS + Android


informative podcast interview
Android on Chrome with Shahid Hussain and Stefan Kuhne - Software Engineering Daily


Apparently there is no plan to "merge" ChromeOS and Android, but to just add Android's 2M+ apps to Chormebooks and make them more usable.

internet split? (ch-exit)

Eric Schmidt, ex-Google CEO, predicts internet bifurcation with China

"...former Google CEO Eric Schmidt predicted that the internet will bifurcate into Chinese-led and US-led versions within the next decade..."


"I think the most likely scenario now is not a splintering, but rather a bifurcation into a Chinese-led internet and a non-Chinese internet led by America," he said.

big words, what is the meaning, and what is the difference?


"the division of something into two branches or parts."


"break or cause to break into small sharp fragments"

Cloud Serverless performances compared

The largest benchmark of Serverless providers. – elbstack – Medium

"The configurable parameter for all Serverless functions is the memory size. At AWS the CPU is doubled, when the memory is doubled. At Google this is also the case but only for 128 to 512 MB of memory, for 1GB and 2GB you get a little less additional CPU, actually they provide you with concrete numbers for the CPU power. Respective to following memory size 128,256,512,1024,2048 you get 200, 400, 800, 1400 and 2400 MHz. IBM lets you choose between three memory sizes from 128 to 512MB, but the CPU is fixed. Azure will automatically determine the memory need of the function, but assigns all functions the same computational power."

cloud: Azure Immutable Storage

Microsoft Announces the General Availability of the Immutable Storage Functionality in Azure Storage

"With the immutable storage, feature blobs will be non-erasable and non-modifiable for a specific retention interval. Now Microsoft announced that this new feature is generally available in all public Azure regions after its preview since June of this year."

Write-Once-Read-Many (WORM)



Technically AWS S3 with versioning enabled also keeps previous versions of data, but semantically this is still different behavior.

Rebooting airplane every 248 days

Reboot Your Dreamliner Every 248 Days To Avoid Integer Overflow

"...all Boeing 787 Dreamliners have to be switched off every 248 days. If they are not reset then the generator control units GCUs will go into failsafe mode and the plane will lose all electrical power.
Why exactly?
To quote the FAA directive:
This condition is caused by a software counter internal to the GCUs that will overflow after 248 days of continuous power. We are issuing this AD to prevent loss of all AC electrical power, which could result in loss of control of the airplane..."

"Cloud Printing" on paper and displays

Daily Overview
is a site that is sending selected amazing satellite or aerial views daily by email, and publishing on Instagram and on web.

They also offer prints of those nice images, on paper and on "digital displays",
in collaboration with Cloud Printing NYC

That is an interesting thing, the cost of high resolution 4K TVs is now lower than cost of comparable good quality prints of pictures!
And those TV's are quite thin, and often come with smart voice agent...

C# span vs. GoLang slice

Span in .NET, C# and other languages | Tudor Turcu – blog

slices

C#
var arr = new byte[10];
var slice = new Span(arr, 5, 2);

Go:
var arr [10]int
var slice = arr[5:7]

"In both languages, a span(C#) or a slice (Go) represent a similar concept:
  • C#: ‘Span is a value type containing a ref and a length‘ , ‘represent contiguous regions of arbitrary memory‘
  • Go: ‘Slice is a descriptor for a contiguous segment of an underlying array and provides access to a numbered sequence of elements from that array‘"

The principles of versioning in Go 1.11 (vgo):
  1. Compatibility
  2. Repeat-ability (no automatic upgrades!)
  3. Cooperation (between authors of packages)

GitHub - golang/vgo: [mirror] Versioned Go Prototype
"This repository holds a standalone implementation of a version-aware go command, allowing users with a Go 1.10 toolchain to use the new Go 1.11 module support."

"dep is a dependency management tool for Go. It requires Go 1.9 or newer to compile."

Cloud-Native Beyond Kubernetes

Beyond Kubernetes - 5 Promising Cloud-Native Technologies To Watch  @ Forbes

"After Kubernetes,Istio is the most popular cloud-native technology. It is a service mesh that securely connects multiple microservices of an application.

Prometheus is a cloud-native monitoring tool for workloads deployed on Kubernetes.

If Kubernetes is the new OS, Helm is the application installer.

Spinnaker is a release management tool that adds velocity to deploying cloud-native applications.

Kubeless is one of the most popular serverless projects in the cloud-native ecosystem. Its compatibility with AWS Lambda combined with the support for mainstream languages makes it an ideal choice"

Angular ngrx-data

Redux pattern, and ngrx, tend to produce a lot of repetitive code. There is a possible solution:

GitHub - johnpapa/angular-ngrx-data: Angular with ngRx and experimental ngrx-data helper


"Zero Ngrx Boilerplate

You may never write an action, reducer, selector, effect, or HTTP dataservice again.

NgRx helps Angular applications manage shared state in a "reactive" style, following the redux pattern.

But to use it properly requires both a deep understanding of redux/ngrx and a lot of boilerplate code.

Ngrx-data is an ngrx extension that offers a gentle introduction to ngrx/redux without the boilerplate.

Try it! See the Quick Start for instructions on adding NgRx and ngrx-data to your app.

This is a library for ngrx, not an ngrx alternative."

Android Actions & Slices

A new way to integrate mobile apps with mobile OS (search box)
