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..

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.

  • FAQ: What's so special about 802.11ad Wi-Fi?
    Here are the broad strokes about 802.11ad, the wireless technology that’s just starting to hit the market.
  • 2.5 and 5 Gigabit Ethernet Now Official Standards
    In 2014, multiple groups started efforts to create new mid-tier Ethernet speeds with the NBASE-T Alliance starting in October 2014 and MGBASE-T Alliance getting started a few months later in December 2014. While those groups started out on different paths, the final 802.3bz standard represents a unified protocol that is interoperable across multiple vendors. The promise of 2.5 and 5 Gbps Ethernet is that they can work over existing Cat5 cabling, which to date has only been able to support 1 Gbps. Now with the 802.3bz standard, organizations do not need to rip and replace cabling to get Ethernet that is up to five times faster. "Now, the 1000BASE-T uplink from the wireless to wired network is no longer sufficient, and users are searching for ways to tap into higher data rates without having to overhaul the 70 billion meters of Cat5e / Cat6 wiring already sold," David Chalupsky, board of directors of the Ethernet Alliance and Intel principal engineer, said in a statement. "IEEE 802.3bz is an elegant solution that not only addresses the demand for faster access to rapidly rising data volumes, but also capitalizes on previous infrastructure investments, thereby extending their life and maximizing value."
  • A quick fix for stupid password reset questions
    It didn’t take 500 million hacked Yahoo accounts to make me hate, hate, hate password reset questions (otherwise known as knowledge-based authentication or KBA). It didn't help when I heard that password reset questions and answers -- which are often identical, required, and reused on other websites -- were compromised in that massive hack, too. Is there any security person or respected security guidance that likes them? They are so last century. What is your mother’s maiden name? What is your favorite color? What was your first pet’s name?
  • French hosting provider hit by DDoS close to 1TBps
    A hosting provider in France has been hit by a distributed denial of service attack that went close to one terabyte per second. Concurrent attacks against OVH clocked in at 990GBps. The attack vector is said to be the same Internet-of-Things botnet of 152,464 devices that brought down the website of security expert Brian Krebs. OVH chief technology officer Octave Klaba tweeted that the network was capable of attacks up to 1.5TBps.
  • Latest IoT DDoS Attack Dwarfs Krebs Takedown At Nearly 1Tbps Driven By 150K Devices
    If you thought that the massive DDoS attack earlier this month on Brian Krebs’ security blog was record-breaking, take a look at what just happened to France-based hosting provider OVH. OVH was the victim of a wide-scale DDoS attack that was carried via network of over 152,000 IoT devices. According to OVH founder and CTO Octave Klaba, the DDoS attack reached nearly 1 Tbps at its peak. Of those IoT devices participating in the DDoS attack, they were primarily comprised of CCTV cameras and DVRs. Many of these types devices' network settings are improperly configured, which leaves them ripe for the picking for hackers that would love to use them to carry our destructive attacks.

  • Goodbye QWERTY: BlackBerry stops making hardware
    BlackBerry CEO John Chen has been hinting at this move for almost a year now: today BlackBerry announced it will no longer design hardware. Say goodbye to all the crazy hardware QWERTY devices, ultra-wide phones, and unique slider designs. Speaking to investors, BlackBerry CEO John Chen described the move as a "pivot to software," saying, "The company plans to end all internal hardware development and will outsource that function to partners. This allows us to reduce capital requirements and enhance return on invested capital." The "Outsourcing to partners" plan is something we've already seen with the "BlackBerry" DTEK50, which was just a rebranded Alcatel Idol 4. Chen is now betting the future of the company on software, saying, "In Q2, we more than doubled our software revenue year over year and delivered the highest gross margin in the company's history. We also completed initial shipments of BlackBerry Radar, an end-to-end asset tracking system, and signed a strategic licensing agreement to drive global growth in our BBM consumer business." BlackBerry never effectively responded to the 2007 launch of the iPhone and the resulting transition to modern touchscreen smartphones. BlackBerry took swings with devices like the BlackBerry Storm in 2008, its first touchscreen phone; and the BlackBerry Z10 in 2013, the first BlackBerry phone with an OS designed for touch, but neither caught on. BlackBerry's first viable competitor to the iPhone didn't arrive until it finally switched to Android in 2015 with the BlackBerry Priv. It was the first decent BlackBerry phone in some time, but the high price and subpar hardware led to poor sales.
  • Oracle's 'Gamechanger' Evidence Really Just Evidence Of Oracle Lawyers Failing To Read
    Then on to the main show: Oracle's claim that Google hid the plans to make Android apps work on Chrome OS. Google had revealed to Oracle its "App Runtime for Chrome" (ARC) setup, and it was discussed by Oracle's experts, but at Google I/O, Google revealed new plans for apps to run in Chrome OS that were not using ARC, but rather a brand new setup, which Google internally referred to as ARC++. Oracle argued that Google only revealed to them ARC, but not ARC++ and that was super relevant to the fair use argument, because it showed that Android was replacing more than just the mobile device market for Java. But, here's Oracle's big problem: Google had actually revealed to Oracle the plans for ARC++. It appears that Oracle's lawyers just missed that fact. Ouch.
