Review or Delete Duplicate Files with Python.

• December 22, 2018 • Comments Off on Review or Delete Duplicate Files with Python.

My music and photos were getting out of hand. Thought I would share.

Author: C. Nichols,
Release: Dec. 2018

Simple script to review or remove duplicate files in a folder.
** Does not delete unless specifed.

TO RUN: See config:
    * Set dir        - path to check.
    * Set do_deletes - delete or review log mode.
    * Set log_name   - Log is unique to each run with datetime.
    * Run in terminal, cd to the folder you saved to script to and type:
import os
import datetime

Extract CAB files with Python and Patool.

• December 21, 2018 • Comments Off on Extract CAB files with Python and Patool.

Install 7zip.

This assumes you are on Windows.

Add the 7zip path to the system path. In the searchbar type env and open the result. Click Environment Variables in the dialog. Add to PATH. Windows 10 just click add and browse to the folder 7zip installed to, i.e., C:\Program Files\7-zip. Otherwise, paste the path making sure it’s at the end of the line followed by a ;

With Python installed, I use 3.7, open the terminal. In the searchbar type cmd and open the result. In the terminal type: pip install patool

You are all set. The only thing I found, and this is likely to do with 7zip, is when extracting many CABS to a single destination it hangs. I did not test this using 7z.exe directly. Just create a folder for each CAB you extract and move the extracted files to a single folder.

Here’s one I wrote to extract all the crap in DirectX9 from MS separated by 32/64 bit.

import os
import shutil

    if not os.path.exists(dest):

        for cab in os.listdir(source):
            cab = cab.strip().lower()
            if not cab.endswith('.cab'): continue
            sub_folder = os.path.join(dest,cab.split('.')[0])

            full_source = os.path.join(source.lower(),cab)
            print('extracting %s' % sub_folder) 
            patoolib.extract_archive(full_source, outdir=sub_folder, program=prg)
    tmpx86 = os.path.join(dest,'tmp', 'x86')

Linux for Graphic Artists and Designers: A real world setup.

• December 15, 2018 • Comments Off on Linux for Graphic Artists and Designers: A real world setup.

I know a lot of Linux and software bloggers write often about the “Photoshop killers this” and the “best Linux/open source that” but I want to add my two cents as a long time Linux and open source user – early nineties to present – who does graphic design. I’m also not gaining financially to pump out those types of articles. I have been writing about this stuff before it was popular and my previous site here had a good following for Linux tutorials and free software listings, even though I’m not the best writer. 🙂 I switched to WordPress a few years ago and rarely update these days since the internet is flooded with similar content, but from time to time I like to think about what I’m doing and how I can share my experiences.

Over the many years I have done graphics I have worked on BeOS, Linux, Mac, and Windows. I have software all over the place for all four OSes. On Windows I think Adobe used to be the best option by far, not that their software was super amazing as you can make art in PaintBrush if you really want to, but rather for the plug-ins, brushes, and ease of use. I swicthed to OS X as my main OS for a few years only using Linux for programming. Of course I ran out and bought Photoshop 7 so I could have the best on Mac, but I lost interest because the software really never changed over the years. Sure, they move things around, make things easier, but honestly there wasn’t a huge change and the software does what it always did.

So my Macbook Pro was finally deemed too old for Apple to support so I decided, considering the apps in the App store are really not any better than their open source cousins I’ve used over the years, that their model isn’t really for me just like Microsoft years earlier. I honestly don’t want to spend $5k to $7k for a decent machine or be controlled by any corporation. Apple is now like Microsoft, maybe worse at this point. I decided to buy a powerful laptop with 16gb ram, fast solid state drives, 12 core i7 latest gen. CPU, and mid-range Nvidia, and best of all, a 17″ display. I ended up with a System 76 machine to support Linux even more and considering the cost to rent Adobe, which is unfortunate because CS6 is the best of the product line ever, I don’t think I’ll miss being billed to work and play.

Actual specs-
Screen size: 17″
Ram: 16gb
CPU: Intel® Core™ i7-8750H CPU @ 2.20GHz × 12
Video: Intel® UHD Graphics 630 (Coffeelake 3×8 GT2) Nividia 1060
Disk 1: 250 gb solid state
Disk 2: 1 tb solid state.

Now you have a bit of background on me let’s get into my choice of Linux and desktop environment. I had the machine shipped with System 76’s Pop! OS, which is a tweaked Ubuntu 18.04 and Gnome 3. I hated it! The core, however, is solid and their drivers and driver support is tops. After giving LinuxMint, Deepin, and Manjaro a try I switched back to Pop and installed Budgie to make it more like OS X. I am not a fan of Gnome 3. Budgie gave me a little trouble but with a little tweaking I find it to be the best environment I’ve worked in for a while. Now that the OS is solid and secured it was time to install the software, and soon after I got a gig to do a bookcover, so away we go.


For the bookcover I needed to create a scroll logo and graphic element. This choice was easy, Inkscape! I have nothing bad to say about Inkscape. It works and works well. For Vector work I have been using it on Windows, Mac, and Linux for years. It does the job of Adobe Illustrator so I never bought a copy. It is the most consistently good application in the open source world.


Gimp worked well with a big image where Krita gave me some trouble. I paint in Krita at high res and had not had this problem before so it may be the latest version I used. I think Krita is as close to Photoshop as you’ll get in the opensource world and it is typically just fine, I won’t fault Krita, it’s really solid and under heavy development. Either way, Gimp did the job of adjusting the image to get it ready for print at 300dpi.

What you lose using these tools. Gimp is a bit of a learning curve from Photoshop, Krita not so much. The way I see it Gimp makes you work harder, or learn the non-automated way to get things done. If you need nice brushes and easier effects use Krita, if you don’t care either tool will do so pick the interface that suits you.

Plug-ins are basically non-existant. Gimp has a few really good plug-ins but finding them and finding versions that work with newer versions can be frustrating. This leads to my biggest complaint against open source, people create and abandon projects/web-sites often so unless you are willing to edit code you have to sometimes wait for others to find an interest in keeping things updated and available.

If you need Gimp plug-ins for versions < 2.8, some work on 2.10 for me, try the Gimp Plugin Registry archive (yes, it is dead as of this writing). Another option is to try other flavors. If you want Resynthisizer, G’Mic, etc. go here.

Other Gimp goodies, Gimp Paint Studio

For Windows users using Gimp 2.10: Gimp Extensions

Some updated plug-ins for Gimp 2.10 and G’Mic for Gimp and Krita

Multiple plug-ins


I don’t do a lot of layout and for the little things I do I typically use LibreOffice Draw. For the book I found wrapping text painful in Draw so I installed the latest Scribus 1.5.5 SNV. It took me a day to figure it out, mainly wrapping text properly, but once I got it down I found this to be excellent software! I do not typically use PageMaker/InDesign so I cannot compare, but the software worked as expected and took only a day of learning and another half day to get everything put together. Book went to print and the customer was extremely happy. This tool will stay in my toolbox. I will admit I poked around for other layout programs for Linux. I was not thrilled with my findings, still you might want to try the alternatives.

I tried VivaDesigner. This is a commercial product and compared to the big boys the price was a bit high for a lower end alternative, strike one. The Linux installer was outdated and would not install on my machine, strike two. I installed the Windows version in Wine, seemed limited for a pay product, strike three.

I also tried Pagestream, another commercial offering. After installing a library it started right up but it seemed limited and dated. It could be a great product, I simply decided not to invest in learning it.

Scribus won simply because it’s full featured, not confusing, and free, but you do have options if Scribus isn’t what you want.

Business Side


When all is said and done you need to get the product to the client. I use Filezilla as it’s the best FTP app IMO.

Now that the tools were picked and product has been delivered I’ll go into the administrative tools that I use that others fail to mention.

Kapow Time Tracking

I like to track my time when I start working on a project so I can give detailed billing. This tool is one that I was going to write until I found Kapow. I was a little bummed it already existed. Oh well. This tool will track time on tasks in real-time. You could just write down start and end time but this is so convenient.


If you’re on larger/longer projects and/or working with teams Planner Project Management may be for you. I have it for this purpose to keep track of everything.


Osmo is a nice personal task manager. It will keep you on track.


For backups and revision I use Mercurial with TortoiseHG. Better safe than sorry.

Office, etc.

For invoicing I designed a simple template in LibreOffice and all other tools are stock Gnome/Ubuntu apps, like Geary for mail, Gnote, Gnome Calender, etc.


Screen Ruler

GNOME Color Manager. Link to color info, the program is in the software repo like many of the others.

Font Manager

Birdfont Create your own fonts.

PDF of my complete software catalog. Download as PDF

In conclusion, I find this workflow to be just as powerful as the expensive alternatives, at least for me. If you do occasional freelance you cannot go wrong with these selections. The best part is that most are also available on Mac and Windows so if you’re not into Linux you can still use or try them freely.

The book can be found on Amazon here.

Python3 Gtk3 Thread Example

Quick Python3 Gtk3 app to execute Python scripts to test long running threads in Gtk3 app. Some things could be better, like the python paths collection and displaying the PID, but I was focused on running threads without freezing the GUI and it just kind of happened. Hope it’s useful to someone.

Create mov,mp4 thumbnails from Python3

• July 31, 2018 • Comments Off on Create mov,mp4 thumbnails from Python3

I was working on a Gtk 3 project to roll up all my iPhone videos into a flowbox for easy locating and processing since iPhone doesn’t name things in a meaningful way and photo managers dump things into not so meaningful folders, thumbnails was a must to locate videos easily. Plus, I wanted to do some Gtk programming.

I started with GStreamer 1.0, which worked, but not for .mov files. This handles MP4 and MOV. I have not tested other types so it might need further tweaks.

Hope it is helpful to someone. I can provide GStreamer code if you need it. It is also Python and is slightly faster.

Brightness fix on System 76 Oryx Pro

• July 8, 2018 • Comments Off on Brightness fix on System 76 Oryx Pro

Backlight Fix System 76 Oynx Pro (2018) GTX1060 update 1/16/2019

Intel never had any problems after the BIOs update so this is focused on Nvidia.
I have a GTX1060 but this may work for other cards, just be sure you have the correct driver for your card and I cannot guarantee you’ll have the same results.

Make sure your BIOs are at the latest firmware.
Update your system if you haven’t done so.
Add the Ubuntu Display repo:

	sudo add-apt-repository ppa:graphics-drivers/ppa
	sudo apt-get update

Switch to Intel if running under Nvidia:

	system76-power graphics intel


Go into the Additional Drivers section and select the Nvidia driver 4.15.x. At this point I had conflicts, you may not. I purged all Nvidia drivers while running under the Intel driver then selected 4.15.x in Additional Drivers again and booted to Nvidia. At this point some folks might get a black screen. I am using Budgie as my DE and did not experience this, it might be more of an issue on Ubuntu than Pop or other drivers, I am not sure.

To get you to a terminal so you can fix it or flip to Intel using the above command: Ctrl+Alt+F1

this might help:

Brightness works consistently now. If this driver becomes available as an update in the official Pop driver list you may not need the Ubuntu PPA.

If an update shows up in Pop! Store for Nvidia Settings 4,15.x install it. Do not install the other Nvidia drivers, especially if you had dependency issues. Some people also black listed the Nouveau driver. I did not need to do this.


I found some apps will not run while using the Nvidia driver. Krita and Blender both fail to start.

Screenshots, click to view:

I did this awhile ago and the 415 driver is showing as installable as seen in the image so either the PPA pulled it in or Pop put this driver up.

I am trying the driver directly from nvidia next.

Version: 410.93
Release Date: 2019.1.3
Operating System: Linux 64-bit
Language: English (US)
File Size: 102.29 MB

Original post below left for reference.

I recently received the System 76 Oryx Pro laptop – June 2018 – and this thing is a beast. If you want more portable go with something else. I decided to get it preinstalled with Pop! OS to see how well it integrated with the hardware. By default most things worked and I really didn’t spend much time configuring or fixing things beyond setting it up for me and my workflow. I did install Gnome Tweaks to alter a couple of things but for the most part the OS is unchanged.

To the problem. Out of the box there was no ability to control brightness on the laptop monitor. I do not use external monitors so I do not know if this will fix anything related to that. To partially fix brightness when using Nvidia in Pop! OS I simply flashed the BIOs and it magically started working. The brightness controls/keys worked in Pop but it stops working after the lid is closed or the machine goes to sleep. This did not work for Nvidia in Mint 19 at all.

Update: The following grub hack does not work! None do, unless you want to install utils and write some scripts to hack things. What I found that does work is to install Linux Mint 19, much nicer OS IMO but this likely works in any Gnome DE, and install this. The control in power settings wont work, but this does and adds color too, but only if you switch to Intel drivers. I assume Intel will work better in Pop too. I also had problems with the System 76 drivers in Mint so install at your own risk. I’m hoping a future Nvidia driver/kernel update will correct the problem at some point.

If you plan to install Windows this laptop is a rebranded Sager Gaming laptop so visit their site for ease of driver lookups. I think it’s a Clevo P650SE.

The second problem was after putting the laptop to sleep/suspend (closing the lid) the brightness controls would stop working until it was rebooted. Irritating! Here’s the fix:

1. Verify the Nvidia driver is installed and in use.
2. Update BIOs firmware if screen brightness slider missing and keyboard keys are not working.
3. Edit the /etc/default/grub file from the terminal.
a. sudo nano /etc/default/grub
b. Change GRUB_CMDLINE_LINUX_DEFAULT from “quiet splash” to “quiet splash acpi_osi=Linux”
c. sudo update-grub

Apple is a shit hole company

• August 22, 2017 • Comments Off on Apple is a shit hole company

I went to upgrade to El Capitan on my MacBook Pro (17-inch, Mid 2009). I added max ram and a solid state drive. I have no problems virtualizing Windows and Linux on this fucker, but Apple decided my 17″ MBP is no longer viable and will not let me upgrade. Yes, I know I can without them, but fuck that! This is outright bullshit! So I went to run XCode, which I hadn’t ran since the last update – I develop more in Windows or Linux in Python or Rust than OS X in XCode – and they broke it. So I go to the AppBore to upgrade and it just spins, so I am not allowed to update XCode either? I am now forced to hack Sierra onto the machine, install Linux and virtualize OS X, or buy a new laptop with a smaller fucking screen. FUCK YOU! I am buying a System76 powerhouse, and maybe a with the money I save, and virtualizing their crap. Either way, I wrote my two cents on the AppStore and of course they will not allow it to go through so here it is:

“I cannot update XCode, because Apple decided that the over priced hardware I purchased, that was 6 months behind other companies when it was new, is not viable for an OS upgrade from El Capitan to Sierra. I run Windows and Linux virtualized on this laptop as well as play games with no issue. Not only that but they broke the XCode I currently have installed, which worked fine until the last update. The reality, the company changes your system preferences without permission, the majority of AppStore apps are horrid, they kill apps in the store often or steal the ideas effectively killing the original app, and ask for way more for older hardware than required to blackmail you into buying new hardware just to run a single OS version above what you’re running already. They are not a small company that needs to command a higher cost to maintain their business or need to fill landfills with viable hardware to keep money rolling in. The iPhone is great but as a company they are worse than Microsoft in the nineties. I’m going to System76 and LinuxMint and I will virtualize OS X from now on. Not worth my time or money anymore…”

Now don’t give me that, “they are protecting you”, “they want to be secure”, “they need to advance” bullshit. If the motherfuckers are using open Unix shit to build off of, don’t fuck it up, don’t mess with my settings, allow good programs into the AppStore, allow Linux and/or open devs a good environment to build in, and stop trying to be an everything greedy business. If Windows was better I’d go back to that as Microsoft has at least wised up a little bit.
