Reddit: Free Project Idea - Physical Internet

Saturday 27th of May 2017 04:18:00 PM

Let's say things with ISP's go south in the near future, would it be possible to create a physical storage cache of popular websites and distribute like a daily subscription? Could you then call yourself an ISP?

I know people are working on distributed solutions, but this could fill a small niche if you don't really need to be connected to the Internet, basically setting up a small web front end on the client side.

Reddit: while read line . How come that it does not generate a lot of IO load?

Saturday 27th of May 2017 03:59:56 PM

This question is expanding the question that I suddenly realized should be valid in PHP (seeing obvious things is difficult, at least for me).

My point is,:while read line ; do ...code... done < file for a large file should generate a lot of IO requests due to the single line read from the file. If the file read is large with short lines.

Now I know that modern spinning commercial grade disk can handle around 100-150 IOps and SD cards should be around 50, so the code should be quite slow even just echoing the line read. (let's say the latency between printed lines should be noticeable)

It is different when one reads a lot of bytes at once (like with the dd switch bs=16K ), in that case the speed of reading sequentially a file (if the file is not fragmented) is more indicative than the IOps, but a sequential read won't generate that much of IO request because every IO reply would carry a lot of payload, not just a single line of data.

Said that, one can quickly verify that reading single lines is super fast (for the eye at least), why?

Is there a sort of buffering implied in the read application or is the OS prefetching the file? (so maybe similar settings are used for PHP)

Maybe also the memory controller in itself does prefetch the data?

I mean I also know that caching data is possible but foresee a read request is not always returning a cache hit, so prefetching may help, but where is it done?

LXer: The Linux port of Dawn of War III will use both OpenGL and Vulkan

Saturday 27th of May 2017 03:48:25 PM
Feral Interactive have just announced some exciting news! The Linux port of Dawn of War III will come with OpenGL as the default, but like with Mad Max you will be able to check a box to enable Vulkan!

Phoronix: Airlie Is Looking At Tournier's Soft FP64 Work For R600-Rats

Saturday 27th of May 2017 02:23:53 PM
A few days ago I wrote about David Airlie's work on a new "r600-rats" branch where he's working on bringing up OpenGL 4.2 support to more Radeon HD 5000/6000 series hardware on R600g that's currently limited to OpenGL 3.3. Some questions arose about the FP64 support...

Desktop: Popcorn Linux, Purism, Distro Hopping, System76, and 2017 Linux Laptop Survey

  • Popcorn Linux OS gives processors a common language
    Thanks to a new operating system called Popcorn Linux, the Navy may be able to speed systems development and cut maintenance. Developed by engineering researchers at Virginia Tech with support from the Office of Naval Research,  Popcorn Linux can compile different programming languages into a common format. The operating system takes generic coding language and translates it into multiple specialized program languages. Then it determines what pieces of the code are needed to perform particular tasks and transfers these instruction “kernels” (the “popcorn” part) to the appropriate function, ONR officials said. Chips for video systems might be programmed in one language and those for networking functions in another. These multicore processors improve computing speed, but they also force programmers to design or upgrade applications based on what programs run on which processors. That means complex systems like battlespace awareness and artificial intelligence that require specialized processors must be manually adjusted so components can interact with each other.
  • Purism's Security Focused Librem Laptops Go Mainstream as GA Begins, with $2.5M in Total Project Funding and 35 Percent Average Monthly Growth
  • Now it’s easier to buy Purism’s Linux laptops
    After running a crowdfunding campaign in 2015 to raise money for a laptop that runs free and open source software, Purism has been able to ship a limited number of 13 and 15 inch laptops, and the corporation is taking pre-orders for a 2-in-1 tablet.
  • Are You a Distro Hopper?
    Is distro hopping a dying sport or have I just gotten too old? When I first started to use Linux I was the quintessential cliche distro hopper. I swapped and switched flavor of Linux seemingly every other day, certain that at some point I’d find the right fit and stop, content with at whatever combination of distro base and desktop environment I’d hit upon.
  • System76 Continues Working On GNOME Improvements For Future Ubuntu
    System76 continues working on improvements to the GNOME stack as part of their transition in-step to using it over Unity 7, in line with Canonical's decision to switch Ubuntu over to GNOME and abandon their grand Unity 8 ambitions.
  • 2017 Linux Laptop Survey
    It has been a few years since last running any Linux hardware surveys on Phoronix, as overall the ecosystem has rather matured nicely while of course there are still notable improvements to be had in the areas of GPUs and laptops. (Additionally, OpenBenchmarking.org provides a plethora of analytic capabilities when not seeking to collect subjective data / opinions.) But now we are hosting the 2017 Linux Laptop Survey to hopefully further improvements in this area.

Software and GNOME: Pass, Popcorn Time, Nixnote2, Grive, Curlew, and GtkActionMuxer

  • Pass – A Simple command-line Password Manager for Linux
    Keep tracking the password is one of the big challenge to everyone now a days since we has multiple password like email, bank, social media, online portal, and ftp, etc.,. Password managers are become very famous due to the demand and usage. In Linux so many alternatives are available, GUI based and CLI based. Today we are going to discuss about CLI based password manager called pass.
  • Popcorn Time Watch Movies and TV Shows On Linux
    ​Watching your favorite TV shows and movies series is what you all guys do every day. Flash, Iron Fist or Moana and many more awesome movies and tv shows that we love to watch. The problems come when you are traveling. Many of your shows or movies are restricted to a particular region and cannot be accessed when you are traveling or want to just quickly watch that awesome flash punch from an episode of 1 month old.
  • Nixnote2 – A Clone of Evernote for Linux
    When I created a list of Alternative Evernote Clients for Linux, the formerly known NeverNote was on the list as NixNote since it hadn’t gained a “2” to its title yet. It has been 4 months since and I decided to give the app its own review for you guys. Without further ado, let’s get to it. NixNote2 (also called NixNote) is an unofficial client of Evernote for Linux. It possesses most of the features Evernote provides including the use of Notebooks, tags, themes, emails, and multiple accounts.
  • Grive – A Dockerized Google Drive Client for Linux
    Not too long ago I reviewed Grive2 as an alternative Google Drive client for Linux. Today, I’ll introduce you to Grive, a Docker implementation for the Google Drive client, Grive2. Docker (if you don’t already know what it is), is a tool designed to benefit both system admins and developers thanks to its use of containers. Docker’s containers provide a way for developers to create and distribute their apps using containers.
  • Curlew is a GTK Media Converter for the GNOME desktop
    There are plenty of free multimedia converters for Ubuntu available, with command-line champ FFmpeg arguably the most powerful of them all. But this power comes with a complexity. Using FFMpeg to convert media through the command line can be intimidating and arcane. Which is why FFMpeg frontends are popular.
  • Dazzle spotlight – Multi Paned and Action Muxing
    The way the GtkActionMuxer works is by following the widget hierarchy to resolve GActions. Since the HeaderBar is a sibling to the content area (and not a direct ancestor) you cannot activate those actions. It would be nice for the muxer to gain more complex support, but until then… Dazzle.
