Putting an old laptop to good use with Xubuntu

Filed under
Ubuntu

One day while perusing the back room where the old hardware is kept, I spotted an old laptop in its docking station buried under some other hardware. At my desk I booted it up and in no time was using Windows 95 but I wondered if I could improve the situation a bit. The obvious choice for a new OS was Linux.

EditThisPagePHP offers collaboration without the wiki

Filed under
Software

If you want to share your knowledge and ideas with others, you set up a blog. If you want to collaboratively edit Web pages and keep track of changes, you use a wiki. If you need a tool that allows you to quickly set up a page that combines blog and wiki features, with some content versioning capabilities thrown in, you need something like EditThisPagePHP, a PHP script that allows you to create Web pages and do some clever things with them.

Linux: Accessing Files With O_DIRECT

Filed under
Linux

A thread on the lkml began with a query about using O_DIRECT when opening a file. An early white paper written by Andrea Arcangeli to describe the O_DIRECT patch before it was merged into the 2.4 kernel explains, "with O_DIRECT the kernel will do DMA directly from/to the physical memory pointed [to] by the userspace buffer passed as [a] parameter to the read/write syscalls. There are better ways to control the page cache than play games and think that a page cache isn't necessary.

More and more organizations are consolidating physical hardware using virtualization. But virtualization technology and tools aren't limited to big-dollar corporations. With the free-as-in-beer VMware Player, and the very cheap VMware Workstation, you too can use this fancy technology to utilize the processing horsepower of cheap multi-core hardware available off-the-shelf.

Whistle while you work

Filed under
Linux

Use Linux or Microsoft Windows, the open source sndpeek program, and a simple Perl script to read specific sequences of tonal events -- literally whistling, humming, or singing at your computer -- and run commands based on those tones. Give your computer a short low whistle to check your e-mail or unlock your screensaver with the opening bars of Beethoven's Fifth Symphony.

Filed under
Software

Being released on November 29, 2006 was the Linux 2.6.19 kernel. However, neither the November 8.31.5 or December 8.32.5 display drivers had appended official support for this kernel. Now with 8.33.6 the fglrx drivers should work fine with X.Org 7.2 RC3 and final.

Proprietary Software and Security Leftovers

  • FilelistCreator is a directory printer for Windows, macOS and Linux

    Many people organize their data into folders to quickly find what they want. The Windows operating system comes with default folders for images, videos, and downloads for example that many users of Windows use. Windows does not really provide good easily accessible options to compare the contents of two folders; this is especially the case if root folders contain hundreds of even thousands of files and folders.

  • Ragnarok Ransomware Targets Citrix ADC, Disables Windows Defender

    A new ransomware called Ragnarok has been detected being used in targeted attacks against unpatched Citrix ADC servers vulnerable to the CVE-2019-19781 exploit. Last week, FireEye released a report about new attacks exploiting the now patched Citrix ADC vulnerability to install the new Ragnarok Ransomware on vulnerable networks. When attackers can compromise a Citrix ADC device, various scripts would be downloaded and executed that scan for Windows computers vulnerable to the EternalBlue vulnerability. If detected, the scripts would attempt to exploit the Windows devices, and if successful, inject a DLL that downloads and installs the Ragnarok ransomware onto the exploited device.

  • Hacker Releases 500,000 IoT Credentials

    One of the biggest issues that IoT has is keeping everything secure. Putting devices online is a double-edged sword: it allows benevolent useful services to connect to it, but it can also allow malicious agents to harvest data from it. This was proven a few days ago when a list of 500,000 IoT credentials made their way onto the Internet. The list was posted on a hacker forum for anyone to see and use.

  • Big tech CEOs are learning the art of the filibuster

    But it’s clear that as prevailing sentiment about big tech companies has darkened, tech CEOs see increasingly little value in having meaningful public conversations. Instead, they grit their teeth through every question, treating every encounter as something in between a legal deposition and a hostage negotiation.

    We saw this in 2018, when the New Yorker profiled Mark Zuckerberg. We saw it again last year, when Jack Dorsey went on a podcast tour. At some point this year Tim Cook will probably give a zero-calorie interview to someone, and if it’s a slow-enough news day I’ll write this column for a fourth time.

Red Hat vs. SUSE vs. Canonical Contributions To The Mainline Linux Kernel Over The 2010s

After last week looking at the AMD/Intel/NVIDIA contributions to the mainline Linux kernel over the past number of years, there were reader requests for seeing how some of the top distributions compare namely Red Hat, SUSE, and Canonical. These graphs today are looking at the contributions by SUSE, Red Hat, and Canonical to the mainline Linux kernel. Keep in mind this is the Git commits made from using the respective corporate domains for each organization. Read more

Linux on AMD: Audio Issue Tackled and AMD Zen 3 CPU Support

  • AMD Prepares Fix To Address Clicking Issue With Audio Playback On Raven APUs

    Unfortunately it wasn't a trouble-free experience at launch but with time Raven Ridge APUs have been getting cleaned up on Linux for a pleasant experience, thanks in part to the Google Chromebook play that has also seen these newer AMD APUs seeing HDCP content protection support and PSP / TEE trusted execution functionality. The latest overdue improvement on the AMD Raven APU front is a fix for a pesky issue during audio playback. If playing audio streams immediately one after another, clicking noises can be heard. That is in the process of being resolved thanks to a new kernel patch.

  • AMD ZEN 3 CPU Added To Official Linux Kernel With ‘Family 19H’ Indicating Launch Of Next-Gen Processors With Higher IPC Gains?

    AMD’s ZEN 3 Architecture, the next-gen evolution of the company’s powerful CPUs, is now officially a part of the Linux Family. Spotted inside the Linux Kernel are direct references to the AMD’s Zen 3 CPU microcode. Given the recent developments about the as-yet-unannounced AMD Architecture that succeeds ZEN 2, it is quite likely the company could release the new CPUs based on ZEN 3 in the coming months. And, if the leaked benchmarks and test scores are to be believed, AMD has truly pushed its processors and managed to achieve a substantial leap in processor power with lesser power draw. After giving a tough competition to Intel last year, AMD appears to be readying a new lineup of CPUs that are based on the company’s latest Architecture, the ZEN 3. Based on the 7nm Fabrication Node, the Zen 3 is the 3rd iteration of the ZEN microarchitecture, which is built using the EUV (Extreme Ultraviolet) lithography process.

  • AMD Zen 3 CPU Support Added To Linux Kernel As We Get Closer To Official Announcement

    It looks like we are getting more closer to the launch of AMD's Zen 3 CPUs as microcode for the upcoming lineup has been added to the Linux Kernel, as spotted by Komachi. The AMD Zen 3 line of processors are aimed to hit in the coming quarters and it looks like they are going to be a bigger upgrade than we have anticipated as many leaks and official representatives have stated. [...] However, this means that in the upcoming months, AMD is definitely bringing us more news as also stated by AMD's CEO, Dr. Lisa Su, in the 'The Bring Up' interview where she states that Zen 3 architecture is doing really well, they are excited about it and that she looks forward to talking more about it later in 2020.
