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..

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.

How to get APT to work through a proxy..

APT is the core of package management on Debian based systems, its a powerful suite of tools for getting and managing packages onto the system.

As powerful as the Apt suite is, it has problems as I found out this week working through a proxy server. Something i've recently implemented.

KDE4 and Plasma 5 for Slackware

  • KDE4 and Qt4 deprecation in FreeBSD
    This is a reminder — for those who don’t read all of the FreeBSD mailing lists — that KDE4 is marked deprecated in the official ports tree for FreeBSD, and will be removed at the end of this year (in about 20 days). Then Qt4 will be removed from the official ports tree in mid-march. Since both pieces of software are end-of-life and unmaintained upstream already for several years, the kde@ team at FreeBSD no longer can maintain them. Recent time-sinks were dealing with OpenSSL 1.1.1, libressl, C++17, .. the code is old, and there’s newer, nicer, better-maintained code available generally by replacing 4 with 5.
  • KDE Plasma 5 for Slackware – end of the year edition
    I just uploaded a whole new batch of packages containing KDE Plasma5 for Slackware. The previous batch, KDE 5_18.10 is already two months old and has some library compatibility issues. The new KDE 5_18.12 for Slackware consists of KDE Frameworks 5.53.0, Plasma 5.14.4 and Applications 18.08.3. All this on top of Qt 5.11.3. Compiled on the latest Slackware -current, it’s running smoothly here on my laptop. I decided against upgrading to QT 5.12.0. This is a new LTS release, but I will wait for the other distros to find bugs in this new software. Next week, KDE will release KDE Applications 18.12.0 and that too is something I want to check a bit before releasing Slackware packages. Therefore it’s likely that a new batch of packages containing Qt 5.12 and KDE Applications 18.12 will see the light shortly after the New Year.

Programming: GCC, LLVM, Rust, Ruby and Python

  • GCC 9 Guts Out The PowerPC SPE Support
    It should come as no surprise since it was deprecated in this year's GCC 8 release, but the PowerPC SPE code has been removed. This isn't to be confused with conventional POWER/PowerPC but rather PowerPC SPE that is for the "Signal Processing Engine" on older FreeScale/IBM cores like the e500. It's not all that important these days and doesn't affect newer versions of the 64-bit Power support.
  • LLVM's OpenMP Runtime Picks Up DragonFlyBSD & OpenBSD Support
    Good news for those using the LLVM Clang compiler on OpenBSD or DragonFlyBSD: the OpenMP run-time should now be supported with the latest development code.
  • Nick Cameron: Rust in 2022
    In case you missed it, we released our second edition of Rust this year! An edition is an opportunity to make backwards incompatible changes, but more than that it's an opportunity to bring attention to how programming in Rust has changed. With the 2018 edition out of the door, now is the time to think about the next edition: how do we want programming in Rust in 2022 to be different to programming in Rust today? Once we've worked that out, lets work backwards to what should be done in 2019. Without thinking about the details, lets think about the timescale and cadence it gives us. It was three years from Rust 1.0 to Rust 2018 and I expect it will be three years until the next edition. Although I think the edition process went quite well, I think that if we'd planned in advance then it could have gone better. In particular, it felt like there were a lot of late changes which could have happened earlier so that we could get more experience with them. In order to avoid that I propose that we aim to avoid breaking changes and large new features landing after the end of 2020. That gives 2021 for finishing, polishing, and marketing with a release late that year. Working backwards, 2020 should be an 'impl year' - focussing on designing and implementing the things we know we want in place for the 2021 edition. 2019 should be a year to invest while we don't have any release pressure. To me, investing means paying down technical debt, looking at our processes, infrastructure, tooling, governance, and overheads to see where we can be more efficient in the long run, and working on 'quality of life' improvements for users, the kind that don't make headlines but will make using Rust a better experience. It's also the time to investigate some high-risk, high-reward ideas that will need years of iteration to be user-ready; 2019 should be an exciting year!
  • A Java Developer Walks Into A Ruby Conference: Charles Nutter’s Open Source Journey
    As a Java developer, Nutter began looking for an existing way to run Ruby within a Java runtime environment, specifically a Java virtual machine (JVM). This would let Ruby programs run on any hardware or software platform supported by a JVM, and would facilitate writing polyglot applications that used some Java and some Ruby, with developers free to choose whichever language was best for a particular task.

  • Gnocchi: A Scalable Time Series Database For Your Metrics with Julien Danjou - Episode 189
    Do you know what your servers are doing? If you have a metrics system in place then the answer should be “yes”. One critical aspect of that platform is the timeseries database that allows you to store, aggregate, analyze, and query the various signals generated by your software and hardware. As the size and complexity of your systems scale, so does the volume of data that you need to manage which can put a strain on your metrics stack. Julien Danjou built Gnocchi during his time on the OpenStack project to provide a time oriented data store that would scale horizontally and still provide fast queries. In this episode he explains how the project got started, how it works, how it compares to the other options on the market, and how you can start using it today to get better visibility into your operations.

Best Lightweight Linux Distros for Older Computers

Don’t throw away that old Pentium III tower and CRT monitor just yet! While that old laptop in the closet may not be able to run Windows 10 or macOS Mojave, it doesn’t mean it’s destined for the dump. Many Linux distributions are made specifically for utilizing the ancient, underpowered hardware found in older machines. By installing these lightweight distros, you can breathe new life into an old PC thought to be long past its prime. Here are the best lightweight Linux distros that we’ve picked out from the pile.
