Free and Powerful Equalizer for Windows 10

Helge Klein - Tue, 01/29/2019 - 07:23

Windows 10 does not come with an equalizer. That can be annoying when you have headphones that are too heavy on the bass, like the Sony WH-1000XM3. Enter the free Equalizer APO with Peace, its UI.

What You Get

Peter’s Equalizer API Configuration Extension (Peace) is pretty easy to use while offering powerful features:

  • Slider changes have an immediate effect
  • Settings can be applied to invididual devices only
  • Great flexibility
  • Saved configurations
  • Easy backup and restore of configurations
  • Can be started at logon so that configured settings are always applied

The UI looks like this (showing my adjustments for the Sony WH-1000XM3):

Installation

Installation is straightforward. Just make sure to install in the following order

  1. Engine: Equalizer APO
  2. UI: Peace Equalizer

Enjoy!

RISC OS on youtube

The Iconbar - Sat, 01/26/2019 - 10:14
The video sharing site youtube is always an interesting place to find tutorials and see what other people are up to. There are some nice tutorials on how to update your RaspberryPi software, requests for help and people showing off their systems. There is plenty going on - what is your favourite link?

Latest RISC OS content on youtube can be from here.

Modern Multi-Process Browser Architecture

Helge Klein - Tue, 01/22/2019 - 17:26
Contents

An architecture overview of current browsers on Windows: Chrome, Firefox and Internet Explorer.

In case you are wondering: I did not include Edge because it is currently being transitioned to the Chromium rendering engine, which might change a few things. I did include Internet Explorer because it is still the default browser in many enterprises.

Looking for a way to monitor web app performance? Take a look at uberAgent, our user experience & application performance monitoring product.

Chrome Architecture

Chrome was the first browser with a multi-process architecture. Put simply, it encapsulates all logical functions in separate processes. More specifically:

  • One main (browser) process
  • One GPU process
  • Each tab: dedicated process
  • Each extension: dedicated process

Chrome is the only browser with a useful task manager. It can be opened with the keyboard shortcut SHIFT+ESC. As you can see below, Task Manager lists all active Chrome processes with their designated functions. For each process, it shows CPU, network and memory resource usage. It also indicates whether frames are hosted in their page’s process or in dedicated processes (more on that below). Finally, Task Manager shows the Windows OS process ID, which makes it possible to correlate data with other system information tools.

Frames and Site Isolation

Frames share a process with their page if the frame and the page are from the same site (based on the URL).

Starting with Chrome 67, frames from different sites are put into different processes. This is called site isolation and aims to mitigate certain types of attacks. Chrome’s Process Internals page (chrome://process-internals/) lists the current status of each frame.

IE Architecture

IE’s multi-process architecture was introduced with IE8. It makes use of two types of processes:

  • One main (frame) process
  • Zero or multiple tab processes

Note the zero above. Depending on configuration, IE may be limited to just one process – in which case a bug in any component or add-on crashes all opened tabs. Keep in mind that IE add-ons are binary Win32 DLLs that are loaded into the tab process(es). A crash in an add-on also crashes the tab process(es) that host it. This is not the case with modern browsers (i.e., all other browsers), where extensions are basically web apps, built with JavaScript and HTML.

IE Tab Process Count

By default, the number of tab processes is auto-managed depending on the amount of RAM. This can be overridden by setting the TabProcGrowth registry value. It can either be a number (REG_DWORD) or a string (REG_SZ) – which is rather unusual.

A Microsoft blog post explains the TabProcGrowth value. It boils down to this:

Value Type Description 0 REG_DWORD single process for frame+tabs no matter what 1 REG_DWORD single process for frame+tabs per bitness (important for 32-bit add-ons on 64-bit machines) >1 REG_DWORD sets the maximum number of tab processes small REG_SZ max. 5 tabs per session medium REG_SZ max. 9 tabs per session large REG_SZ max. 16 tabs per session

Some notes and caveats:

Firefox Architecture

Historically, Firefox has been a single-process browser. As it turned out, running the browser UI plus the HTML rendering and JavaScript for all tabs in a single process is a bad idea. It easily freezes the UI, and it might not be optimal from a security point of view, either.

Mozilla started project Electrolysis as a gradual move to a multi-process architecture. This took 9 versions, from Firefox 48 to 56. The current architecture looks like this:

  • One main process
  • One GPU process
  • One extension process
  • Up to 4 content (tab) processes

The current default of 4 content processes might be changed in future versions. At this point, it can be increased to a maximum value of 7 content processes. Work is underway to encapsulate extensions in dedicate processes.

Summary

Browsers are evolving quickly – except for IE, of course. Microsoft is focusing on Edge. To be very clear: IE will not get any new features. It’s security updates only for the former world’s most popular browser who once had a market share of approximately 95% (in 2003).

It seems there is no way around the multi-process type of architecture. Benefits include increased stability and security. On the downside, we have an increased overhead.

What’s on the Edge?

Theresa Miller - Tue, 01/22/2019 - 06:54

This year many organizations will kick off edge projects. Since this is a hot space, the terms and content you come across may seem contradictory and confusing. What are the terms you’ll need to know to get started with Edge Computing? Defining Edge Computing It’s always good to define terms, so when you’re discussing projects […]
