epub02Converting a PDF to ePUB format isn’t difficult, but getting quality results seems to be nigh on impossible.

DevelopRx assembled a team of crack engineers (actually just me) to tackle this issue and solve it using readily available open source software (a.k.a. FREE!).

The process described in this article is primarily for text-based PDFs with common headers and footers otherwise known as “books.”

[Rx] Foxfire Security Add-ons

ff001Life was simpler before we knew supposedly non-evil companies collected our every little click on the Internet and sold the data to the highest bidder.

Surfing the net, you can get tons of opinions but seldom a definitive answer on how to best protect yourself. It’s always an answer like, “it depends.” I’m not a security expert but this is what I use…

How to Install Semi-bold and Other Font Variations for Word/PowerPoint

Font_banner

If Microsoft Word and PowerPoint don’t recognize fonts styles other than bold or italic even if other styles are installed, there is a hack.

I found the perfect font to use for titles in a presentation, Raleway Semi-bold. I installed it and when I went back to PowerPoint, I had two options: bold and italic. So, where’s semi-bold? A quick search found that it’s a MS-Office problem. A hack around it was to remove all other variations of the bold font, except for the semi-bold. This would be great unless I wanted to use the actual bold font. My solution was to rename the Semi-Bold Raleway font and install it as a “new” font.

If you’re looking for a “light” alternative to WordPress that doesn’t require a massive learning curve, PHP-driven HTMLy just might fit the ticket.

HTMLy a simple PHP CMS program that stores all the posts in Markdown. It’s also open source and free. It looks like recent development is a few months old, which is a concern.

The good news is that the github issue forum is active.

[Rx] Customizing Open Live Writer

olw_01Way back in the day, Microsoft gave out a very good offline blogging program called Windows Live Writer. It was an offline WYSIWYG blog editor that allowed you to write, save, and post all from the comfort of your local PC desktop and came bundled in an online package called Windows Essentials. The program stalled out on version Windows Live Writer 2012. Microsoft opened sourced the program as Open Live Writer at the end of 2015.

Like the older version, it’s possible to tweak the theme and to make it look more like your blog.

[Rx] Jupyter Notebook–-Select Browser

2015-10-28_091835Jupyter Notebook is an interactive computational environment to run code, add rich text, compute mathematics, draw plots, and add rich media–all in the comfort of your browser.

I have a variation of Firefox, Palemoon, running as my default browser. When I run Jupyter Notebook, I wanted it to open in the Chrome browser.

It looked like a simple command line switch would do the job:

Jupyter Notebook -–browser=”chrome”

That doesn’t work. I tried it without quotes and single quotes. I’ve got a bald spot on the side of my head trying to figure this one out. There’s not much on the web.

Here’s how to do it:
