With the latest Kubuntu 15.10 (Wily)

Filed under
Just talk

I love the KDE desktop—I really do. However… here are some grumbles.

Issues with Kubuntu 14.10

Filed under
Linux

I installed Kubuntu 14.10 a couple of weeks ago. Here's two issues I've discovered, the first one is solved, but the 2nd one isn't.

1) Kdenlive will play videos from the Clip Monitor, and in the Project Monitor. However, after rendering the video, audio is lost.

2) It's not possible to mount an nfs share automatically in /etc/fstab. You have to use
sudo mount -a and enter the root password.

Computer Equipment and Screen Recording Revisited

It has been about 3 years since my primary hardware machine has been upgraded. I already had 16GB of RAM, two 1920 x 1200 monitors, a Filco mechanical keyboard, and a graphics tablet. OK, I admit that the CPU is showing a little age, but it was an AMD Phenom II X4 965 quad-core processor, and that still has some life left in it.

So I decided to update my graphics card, which was an Nvidia GeForce 440.

Mandrake Derived Distros

Filed under
Linux

Todays special is about Mandrake derived distributions, namely,
OpenMandriva Lx 2014 alpha vs Mageia 4 final vs ROSA 2012 R2 final vs PCLinuxOS 2013.12 final.

In (my limited) testing, I've used the X86_64 versions favoring the KDE desktop, and I've used the NVidia binary drivers provided with each distro.

Here's my experience with each one:

PCLinuxOS 2013--An Old Friend Revisited

Filed under
Linux

I first heard about Bill Reynolds (AKA "Texstar") when I was using Mandrake Linux 7 (later called "Mandriva") many years ago. Back then, Texstar was putting together updated KDE releases for Mandrake Linux, as Mandrake would only typically update their KDE release once or twice a year.

Windows 8.1 "The Worst Ever"

Filed under
Just talk

I've taught High School Computer Science for 25 years--Computer Programming, Web Page Design, Word Processing, Database Processing, and Spreadsheet processing. I have Linux on all my home computers with a dual boot into MS Windows 7 on my main computer. I don't use Windows 7 very often--but, I can find my way around in Windows 7. Since I have no experience with Win 8, I've thought all the recent hoopla about Microsoft's Windows 8 and 8.1 was just inexperienced grousing.

Casual Programming and Linux Screen-Recorders

Filed under
Linux

After being retired (for four years) from teaching high school Computer Science, I decided to get back into programming again. I once taught a beginning programming class using the Ruby language, and I thought that would be a good way to get back into programming. So, I decided I needed a “Ruby refresher”, and I wanted to learn more about that language than I taught in the classroom.

Lost mime types under kde

Filed under
Linux

I downloaded the source to the (video editing) application "kdenlive" (version 0.9 just released), and following the instructions on the kdenlive web site, compiled it, and installed it on my Linux Mageia Cauldron laptop. Maybe I did something wrong, maybe not. Anyway, disaster ensued.

LibreOffice 3.5.0beta2--one person's experience

I've been working on a complex document for the last year or so. This document is now 25 pages long, and includes a dozen images in frames with captions, with text running around the images, a table of contents, Gradient backgrounds on major headings, 2 drawings, varying headers and footers (with borders and shadows), lists, varying page styles, footnotes, and font styles.

I've been working on this document long enough that I started it with openoffice. I then switched to LibreOffice with its first release. And now I'm editing it with the LibreOffice Christmas Eve (2011-12-24) 3.5.0beta2 release.

Invariably, up to now, in a 2 hour work session, openoffice/libreoffice would crash at least once. Sometimes more.

Interestingly enough, this latest LibreOffice beta has not crashed once in three 1 hour work sessions. It may only be a beta, but I'm a believer.

Gook work LibreOffice folk.

Nook Ebook Reader & DRM

I'm 62 years old, and I've always been a reader. So, a few months ago, I finally coughed up the money to purchase a Barnes and Noble Nook ebook reader. Despite being a Linux user and occasionally enjoying tinkering with the innards of things, I haven't rooted my Nook, or installed any other OS variant—it is completely stock.

Unlike my wife's Amazon Kindle (with its E-Ink display), my Nook's battery doesn't last long. The other day I was reading a good short novel I had just downloaded from Barnes and Noble. I'm about half way through the novel when my Nook's battery level gets very low.

Here's the rub: my charger unit has an intermittent electrical short, and I can't immediately plug it in to continue reading while recharging my nook (a couple of days later, I fix this).

But I want to finish reading my novel now! I've got the time, and I'm really into the story.

Hard Drive Purchase and Thailand Flooding

My 2nd desktop is largely reserved for video editing. As it often the issue with video editing, storage space is getting scarce. The sata hard drive has 320 GB, and it's getting full. Time to purchase a new hard disk drive...

BIOS Flash update under linux.

Filed under
Linux

I figured it was time to do a BIOS update on one of my main Linux boxes. The MSI NF 980-G65 AMD motherboard came with an AMI BIOS dated September 2009. This MSI motherboard is based on the NVidia NForce 980a chipset, and has built-in NVidia Geforce 8300 video (which I do not use).

Powering up this system has always been a little flaky, requiring a couple of reset-button presses before it would boot into Linux (it would hang at the BIOS splash screen). After boot-up, the system always ran great.

Alright, so on to the BIOS update. MSI has the live update online program which requires, of course, Microsoft Windows, and the Internet Explorer browser. Well, I don't have these on this system, and don't want to put them on it.

In the AMI BIOS setup program, I see the M-Flash option. I try this, but can't get it to work. Some research on the Internet indicates that it's very likely you'll wreck your BIOS using M-Flash anyway, so that's out.

Mageia 1 Alpha2 -- A Status Report

Filed under
Linux

On September 18, 2010, in response to Mandriva's liquidation of its “Edge-IT” subsidiary and the attendant layoff of a substantial share of its developers, a group consisting of former Mandriva developers and Mandriva community contributers announced their intention to form a non-profit organization and release a fork of Mandriva Linux called Mageia Linux.

How is the Mageia 1 release shaping up? This status report takes a look at Mageia Linux 1 Alpha 2 release (updated daily), from a KDE-user perspective.

Mandriva Linux 2011TP (Tech Preview) - Quick Look

Filed under
Reviews

After laying-off a significant portion of its employees, is Mandriva going to remain a viable distribution? While many distros, including Mandriva, are furiously working on their Spring 2011 releases, Mandriva announced a two-week slip from their previously announced release dates. As a compensation, Mandriva gathered up its packages from its 2011 development repositories (called "Cooker"), and released a pre-alpha 2011 TP (Technology Preview) iso. The coming Alpha version is due to be released February 14 with Alpha2 slated to be released February 28. So, here's a quick report on the Technology Preview release, and how things are shaping up.

Screencasting Under Linux--A brief Story

Since my recent retirement from 34 years of mathematics and computer science teaching, I've been working on creating creating screencasts for teaching how to use various kinds of computer software. So, I need to record my screen while narrating audio. What follows is my story of what it takes to do this under Linux.

Should Pulseaudio Die? What do you think?

Filed under
Linux

When I was installing and testing Mandriva 2010 Cooker (new development) releases this last Fall season, I kept having persistent problems with sound. Eventually, the advice in the Mandriva Cooker forum for KDE users became: "Disable Pulseaudio, and set Xine as the preferred back end over GStreamer (in the KDE multimedia settings).

Desktop Recording on my Laptop

Filed under
Linux

I bought this Acer Aspire 6930 laptop about a year ago. It is my first and only laptop--and came with Windows Vista pre-installed. Since I value good video performance, I selected a sub model of Acer laptop that has on board Nvidia GeForce 9600M GS video (confession time--yes, I use the proprietary NVidia driver). Since it came with Win Vista, I had 3GB of RAM, and a 320 GB hard disk drive. Plenty of horsepower for Linux, except for ...

Recommended: Rosewill Wireless USB 2.0 Adapter 802.11b/g

After teaching high school computer science for 33 years, I had never owned a laptop computer. I'd always wanted one, but they were just too expensive. Finally, last year, after saving up for a long time, I bought a laptop for me, and 6 months later, a laptop for my wife.

The built-in wireless on my wife's laptop has little range, and isn't very reliable.

  • Mike Hoye: Navigational Instruments

    A decade ago I got to sit in on a talk by one of the designers of Microsoft Office who’d worked on the transition to the new Ribbon user interface. There was a lot to learn there, but the most interesting thing was when he explained the core rationale for the redesign: of the top ten new feature requests for Office, every year, six to eight of them were already features built into the product, and had been for at least one previous version. They’d already built all this stuff people kept saying they wanted, and nobody could find it to use it. It comes up periodically at my job that we have the same problem; there are so many useful features in Firefox that approximately nobody knows about, even people who’ve been using the browser every day and soaking in the codebase for years. People who work here still find themselves saying “wait, you can do that?” when a colleague shows them some novel feature or way to get around the browser that hasn’t seen a lot of daylight. In the hopes of putting this particular peeve to bed, I did a casual survey the other day of people’s favorite examples of underknown or underappreciated features in the product, and I’ve collected a bunch of them here. These aren’t Add-ons, as great as they are; this is what you get from Firefox out of the proverbial box. I’m going to say “Alt” and “Ctrl” a lot here, because I live in PC land, but if you’re on a Mac those are “Option” and “Command” respectively. Starting at the top, one of the biggest differences between Firefox and basically everything else out there is right there at the top of the window, the address bar that we call the Quantumbar.

Programming: Cutelyst, C/C++, Perl and Python

  • Cutelyst 2.13 and ASql 0.19 released – Dantti's Blog

    Cutelyst the C++/Qt Web Framework and ASql the ASync SQL library for Qt applications got new versions. Thanks to the work on ASql Cutelyst got some significant performance improvements on async requests, as well as a new class called ASync, which automatically detaches the current request from the processing chain, and attaches later on when it goes out of scope. With the ASync class you capture it on your ASql lambda and once the query result arrives and the lambda is freed and the ASync object gets out of scope and continues the processing action chain.

  • LLVM Lands Very Basic Support For AMD Zen 3 CPUs

    While AMD has landed Znver3 support in GNU Binutils, the company hasn't yet sent out patches for either the GCC or LLVM/Clang compilers in setting up the Zen 3 target with its new instructions or optimized scheduling model / cost table. But a basic implementation has been merged to LLVM for allowing "-march=znver3" based on the limited public details thus far. Merged to mainline LLVM 12 yesterday was a basic implementation allowing for -march=znver3 targeting that basically flips on the new instructions known to be supported by Zen 3. Beyond Zen 2, it flips on INVPCID, PKU, VAES, and VPCLMULQDQ. There are also a few other instructions supported by Zen 3 as outlined in this earlier article.

  • Warning about Python3 update in latest -current | Alien Pastures

    Warning for people running Slackware-current and have 3rd party packages installed (who doesn’t) that depend on Python3. That includes you who are running KDE Plasma5! The “Sun Oct 25 18:05:51 UTC 2020” update in Slackware-current comes with a bump in the Python3 version (to 3.9) which is incompatible with software which already has been compiled against an older version of Python3 (like 3.8). I found 26 of my own packages on my laptop that depend on Python3 and they are all probably going to break when upgrading to the latest slackware-current. This includes Plasma5 ‘ktown’ packages but also several of my DAW packages.

ScummVM Android Love

Our new and shiny Android port for ScummVM v2.2.1 is now live on the Google Play Store. After quite a long period of dedicated work from our team developers, and a month of public beta testing by members of our community who helpfully reported quite a few issues for us to address, we are finally ready to give you the stable release for our ScummVM Android app. This app has been significantly re-written and tested on modern Android devices, running up to Android 10+. It includes new features which bring it up to speed with the desktop ScummVM application, such as FluidSynth support, Cloud Saves and more localization choices for the UI. Also included is the Local File Server (LAN) feature, whereby your device can act as a temporary file server allowing you to download files (eg. save files and even the config file) or upload new ones (eg. game data) using a web browser from a PC or another client.
