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.

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..

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.

Download latest Linux-based LibreELEC Krypton -- Kodi addons like Exodus and Covenant will work

The Kodi media center is facing a lot of scrutiny in the media lately. Some people feel that the negative coverage is "fake news." It is important to remember that Kodi is not illegal. With that said, it can be made so with piracy-related addons. Since Kodi is open source, even if the developers removed the ability to install addons, other people could easily fork the code to add it back. Pandora's box cannot be closed. Many people that use Kodi do so with a dedicated Linux-based operating system, such as the excellent LibreELEC. You see, these distros exist only to run the open source media center, meaning there are no resources wasted on unnecessary things. Today, LibreELEC (Krypton) v8.1.2 BETA sees release. You can install it immediately, and don't worry -- your addons like Exodus and Covenant will work fine. Read more

Arduino unveils tiny, battery powered MKR boards for LoRa and 3G

Arduino launched two 67.6 x 25mm boards for wireless IoT nodes based on Atmel’s SAM D21 MCU: The MKR WAN 1300 offers LoRa, and the MKR GSM 1400 provides 3G. At the Maker Faire in New York this weekend, Arduino unveiled two new “MKR” IoT boards with the same 32-bit, Cortex-M0+ based Microchip/Atmel ATSAMD21 MCU used by last December’s MKRZero. Available for pre-order, with shipment in November, both the LoRa enabled, $39 Arduino MKR WAN 1300 and the 2G/3G ready, $69 Arduino MKR GSM 1400 measure 67.6 x 25mm. That’s only slightly larger than the 65 x 25mm MKRZero and earlier, WiFi-enabled MKR1000. Read more

  • Future Proof Your SysAdmin Career: Advancing with Open Source
    For today’s system administrators, the future holds tremendous promise. In this ebook, we have covered many technical skills that can be big differentiators for sysadmins looking to advance their careers. But, increasingly, open source skillsets can also open new doors. A decade ago, Red Hat CEO Jim Whitehurst predicted that open source tools and platforms would become pervasive in IT. Today, that prediction has come true, with profound implications for the employment market. Participating in open source projects -- through developing code, submitting a bug report, or contributing to documentation -- is an important way to demonstrate open source skills to hiring managers.

    In the age of digitalisation and data centre modernisation, open source has come of age. This is demonstrated by the growth that enterprise open source software provider SUSE has enjoyed over the last months. “SUSE is in good shape,” says Nils Brauckmann, CEO of SUSE. “In the last year, revenue grew at 21%, and it was profitable growth.” Business is positive going forward, he adds, with SUSE now part of the larger mothership Micro Focus group following the completion this month of the HPE Software spin merger. “Micro focus is now the seventh-largest pure-play software vendor in the world, with revenues approaching $4,5-billion,” Brauckmann points out.

  • UbuCon Europe 2017
    I’ve been to many Ubuntu related events before, but what surprises me every time about UbuCons is the outstanding work by the community organising these events. Earlier this month, I was in Paris for UbuCon Europe 2017. I had quite high expectations about the event/location and the talks, especially because the French Ubuntu community is known for hosting awesome events several times a year like Ubuntu Party and Ubuntu install parties.
