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…

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..

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.

15 ways to empower students with open source tools

Recently I read the fascinating book Empower: What Happens When Students Own Their Own Learning, by John Spencer and A.J. Juliani. The book led me to think more deeply about my teaching methods and how I like to learn. I think learning should be exciting, and I'm happiest when I'm actively engaged in what I'm doing. Why wouldn't students in our schools want anything different than that? And why aren't we doing more to give that experience to them? While many schools today have a 1:1 ratio of computers/tablets to students, most of them use platforms and software that allow little (if any) modification. Students can't tinker with the software or hardware. Yet tinkering and experimenting are at the heart of learning. The authors of Empower say that students in environments that foster "making" take ownership of their learning more readily and tend to be deeper thinkers who are more at home with frustration. Ultimately, they wrote, "makers are better equipped for life." Read more

OSS: Yandex, The Open Source Way, Machine Learning, and BSD

  • In Other API Economy News: Yandex Open Source Machine Learning Library and More
    We start your weekend off with a review of the stories we couldn’t cover with a look at what what going on in the world of APIs. We start off with news that Yandex, the Russian search engine company, has announced that they are open-sourcing CatBoost, a machine learning library. The library is based on gradient boosting, a machine learning technique described by TechCrunch as being “designed to help “teach” systems when you have a very sparse amount of data, and especially when the data may not all be sensorial (such as audio, text or imagery), but includes transactional or historical data, too.” Yandex is freely releasing CatBoost for anyone to use under an Apache License. This move is similar to what we saw from Google when they open sourced TensorFlow in late 2015. As the demand for artificial intelligence solutions backed by machine learning platforms continues to grow, moves like this serve to help a wide range of developers take advantage of the technology.
  • CatBoost: Yandex's machine learning algorithm is available free of charge
  • The Open Source Way
    "Open source", in the world of IT, is program code that is meant for collaboration and open contribution. Intended to be modified and shared, because by design and spirit, it is meant for the public at large. It’s been said that “"open source" intimates a broader set of values—what we call "the open source way." Open source projects, products, or initiatives embrace and celebrate principles of open exchange, collaborative participation, rapid prototyping, transparency, meritocracy, and community-oriented development.” So it is a natural conclusion that in this age of open and transparent government, that the government IT manager or technician would be one of the first to want to embrace this new role of collaborative team member within a larger community. Additionally, as organizations, especially government, continue to emerge from the technology funding embargo of the Great (2008) Recession - an economic force that froze IT purchases and programs and forced many into strict “keep the lights on” operational mode, IT managers and CIO’s are carefully expending their still relatively measly budgets. [...] For IT organizations, especially government, with limited budgets and long procurement processes, time and increased experience with open source products will lead to a growing understanding and acceptance. And as this understanding progresses and becomes more accepted, open source will become a “go to” option to keep up with the fast moving technical environment, and perhaps eventually, as a standard first option, realizing the broader set of open source values by relying on the collective work and minds of a virtual community of IT “hackers”, “geeks” and “nerds”, working globally, 24x7/365 to explore, develop and showcase whatever tech that sparks their individual interest.
  • Top 5 open-source tools for machine learning

    Given the paradigmatic shifts that a true revolution in machine learning could bring, it’s important to maintain tech’s devotion to open-source. These kinds of scientific advancement don’t belong to any one company or corporation, but to the whole world. Making ML open and evenly distributed means everyone can join in this revolution.

  • Release of TinySegmenter 0.3
    Today I released version 0.3 of TinySegmenter, a Japanese Tokenizer in pure Python (released in New BSD license), with a single minor fix for proper install on systems not-using UTF-8 (apparently that still exists! :P). Thanks to Mišo Belica for the patch. Apparently some of his Japanese users are using it for Sumy, his software to extract summary from texts.

  • GNOME's Mutter Window Manager Now Supports Tablet Wheel Events on Wayland
    The Mutter composite and window manager of the widely-used GNOME desktop environment was updated recently both on the stable and devel channels with a bunch of new features and improvements. Mutter 3.24.4 is now the latest stable build of the application, and it's here to add a few important changes for tablets, including improved stability of tablet plugs and unplugs, working window moving and resizing via tablet tools, as well as the implementation of tablet rings/strips configuration. In addition, Mutter now no longer throttles motion events on tablet tools, it's capable of handling the left-handed mode on pen/eraser devices, and adds support for tablet wheel events when running under the Wayland display server. Talking about Wayland, the Wacom cursor offset should now work as expected in Mutter 3.24.4.
