How to rename files in bulk

Filed under
Howtos

Consider this common scenario. A directory contains multiple files that are named using a common convention: for example, image-001.png, image-002.png, image-003.png, etc. You want to rename the files to, say, upload-001.png, upload-002.png, upload-003.png, etc.

The coders among us can write a bash script to automate the process. For expedience, this post shows how to use the built-in rename command to achieve the same goal.

Fixing OpenSuse’s Dog Awful default fonts…

Filed under
Howtos

Lets not beat around the bush here, the default font rendering in OpenSuse and the default font do not an OS fit for reading make.. this can be fixed however..

Love or hate Ubuntu, out of the box it has one of the best font rendering setups of any distro and considering how much time we spend on our PC’s setting your fonts up correctly is one less headach, literally.

I’m not sure how much of these instructions I got right, however after a reboot the screen text does at least look better..

Howtos

While being a huge fan of the GNU/Linux OS I do also live in the real world which means using Active Directory Domain Controllers and Windows networks. this week however I’ve had to build for a project a stand alone AD network. This got me thinking to a project I built for a school 6 uears ago which I did the same thing with Samba on Fedora.

Using the right tools to get your media..

Filed under
Howtos

When it comes to getting what you want off the interent, its pretty fair to say, that there is an application and a set of instructions to do this. In this day and age its fair to say that getting media off the web should be the way that media companies distribute. Instead of trying to reinvent the wheel. Unfortunately they don't they bog you down with Websites, DRM, Magma and lots more.. Well This is how to get your media another way..

Big Bear's Helpful Hints-Google Docs Spreadsheets

Filed under
Howtos

I like to jot down things that I learn how to do on the spur of the moment so that I can find it later.

I admit, in the 80's there was quite of bit of "herbal remedy" usage and my short term memory isn't what it could be. That's my story and I'm sticking to it.

I've decided that I might as well potentially help some other folks who might want to know about some of the things I discover, so I thought why not here?

For my very first post, I wanted to figure out how to sum cells across multiple pages in Google Docs spreadsheets.

Zapcc Liberated, HMM and GPL

  • Zapcc high-speed C++ compiler now open source
    Zapcc, a caching C++ compiler built for speed, has gone open source. Ceemple Software, Zapcc’s builder, claims the compiler offers dramatic improvements in both incremental and full builds compared to building with Clang 4.0 and Clang 5.0. Based on heavily modified code from the Clang compiler project, Zapcc uses an in-memory compilation cache in a client-server architecture. All compilation information is remembered between runs.
  • Heterogeneous memory management meets EXPORT_SYMBOL_GPL()
    One of the many longstanding — though unwritten — rules of kernel development is that infrastructure is not merged until at least one user for that infrastructure exists. That helps developers evaluate potential interfaces and be sure that the proposed addition is truly needed. A big exception to this rule was made when the heterogeneous memory management (HMM) code was merged, though. One of the reasons for the lack of users in this case turns out to be that many of the use cases are proprietary; that has led to some disagreements over the GPL-only status of an exported kernel symbol. The HMM subsystem exists to support peripherals that have direct access to system memory through their own memory-management units. It allows the ownership of ranges of memory to be passed back and forth and notifies peripherals of changes in memory mappings to keep everything working well together. HMM is not a small or simple subsystem, and bringing it into the kernel has forced a number of low-level memory-management changes. After a multi-year development process, the core HMM code was merged for the 4.14 kernel, despite the lack of any users.

Software: elementary OS Software, Unified Modeling Language (UML), PulseAudio 12.0 and Zstd

  • An Awesome List of Apps & Resources for elementary OS
    It is barely up to a day since I put up a positive review of elementary OS which is well deserved because it has come a long way from what it was 2 years ago when FossMint checked it out. The good news I’ve got for you today is that the developers have published a page on GitHub that contains “curated list of awesome applications, tools and shiny things for elementary OS”. They are grouped into categories for easy selection, are all open source, and clicking on the green tick icons will direct you to the app on elementary OS’s AppCenter.
  • Best Free Unified Modeling Language Tools
    Unified Modeling Language (UML) is a general-purpose, modeling language designed to provide a standard way for visualizing, specifying, constructing, and documenting the artifacts of distributed object systems. It’s the industry standard modeling language for software engineering. The aim of UML is to give software engineers, agile and small development teams, and system architects useful tools for analysis, design, and implementation of software-based systems. It also provides modeling business and similar processes. The language helps to visualize your object-oriented design and communicate with others. It offers limited use for other programming paradigms.
  • PulseAudio 12.0 release notes
    When playing videos, it's important that the audio latency is known so that the video can be synchronized accurately. PulseAudio doesn't get good latency information from the kernel with A2DP playback, which has caused A/V sync problems for many people when watching videos. Now PulseAudio makes the audio buffer in the kernel much smaller, which reduces the problem a lot.
  • PulseAudio 12.0 Released With Many Improvements
    PulseAudio 12.0 was quietly released yesterday as the newest version of this open-source, cross-platform sound server.
  • Zstandard – A Super Faster Data Compression Tool For Linux
    This is known topic and we were using in our day to day activity to compress and decompress files & folders. You might already know zip,tar,7-zip, etc and you would have used all these application for your requirement. Even today also we are going to discuss about similar kind of topic, the tool name is Zstandard. It is super fast data compression tool and compression ratio is very very low. Zstd is lossless data compression algorithm developed by Yann Collet at Facebook. Due to high data compression ratio many of the popular companies and databases are using this tool.

KDE: CMake 3.12 With FreeBSD, Krita 4.1 Beta, C++/Qt

  • CMake 3.12 Update on FreeBSD
    CMake 3.12 has reached rc1. That means we’re testing the update on FreeBSD, and building lots and lots of packages. And, as I’ve written previously, every CMake update triggers a bunch of interesting software findings. As a motto, I’ve got “use it, aggressively improve it” on my website (you can hire me for odd CMake and C++ jobs, too). So hitting compile issues makes me turn to fixing software outside of KDE.

  • The day Kate Gregory enjoyed Qt
    At my company we use C++ for everything, from creating microservices to website backends and as a generator for website frontends, I mean, we do a lot of c++. And because of that we always need more c++ people, but sometimes it’s hard to find developers, but it’s easy to find php / python / javascript ones. Because of that we hired Kate Gregory’s famous c++ course – “Teaching the Teacher” to train current C++ developers to teach C++. (now, that’s a lot of ‘C++’ in a simple sentence, I know. bear with me.) For those that doens’t know, Kate Gregory is somebody that uses, advocates our beloved language even before I was born, and talks all over the world about C++ and also do trainings for companies, And so I enlisted to be her student. It was a really pleasant course going thru how to proplery explain C++ for people that know how to program but don’t know how to C++, and for that I’m grateful. But then when I commented out about Qt in the middle of the class she rolled her eyes, that made me feel a bit uneasy so I talked to her on why the eye-roll. “Qt is not c++”, and I tougth this was already settled down for years, so I asked her if she would be open to see some simple c++ code written in Qt and tell me what she thinks of it. “Well, Yes. but people already tried and it was not good”.

Red Hat: Kubernetes, 'Cloud', and GlusterFS 4.1.0 Release

  • Kubernetes StatefulSet In Action
    Recently, I stumbled upon a StackOverflow question around StatefulSets which made me wonder how well understood they are at large. So I decided to put together a simple stateful app that can be used to experiment with a StatefulSet. In this blog post we will have a closer look at this app and see it in action. If you’re not familiar with StatefulSets, now is a good time for a refresher, consulting the official docs concerning their usage and guarantees they provide.
  • The road to cloud-native applications
    As many organizations do not have the luxury of completely rebuilding their technology foundation or immediately adopting new practices and mindsets, they can embrace gradual yet fundamental shifts in culture, processes, and technology to help support greater velocity and agility. With software increasingly key to how users engage with businesses and how businesses can innovate to stay competitive, organizations should adapt to the new demands of the Digital Economy, such as speeding up application development and delivery. The cloud-native approach describes a way of modernizing existing applications and building new applications based on cloud principles, using services and adopting processes optimized for the agility and automation of cloud computing.
