This website contains my professional references, contact info and blog posts about my software projects, including but not limited to HTML/CSS, web development, CMS systems, OpenStreetMap, Commodore 64, IDE64 (ex: Xaraya CMS, OpenMoko). For more extensive information on certain topics, please see the list of my websites on the sidebar.
The best way to repair or replace parts of laptops, is to read the service manual. But if you prefer a more visual way, please read on.
Or just read the official HP Compaq 6720s Maintenance and Service Guide here.
This is a command line tool, tested on Linux only. Its use is quite hardcore, but maybe I'll improve that later on. Just wanted to publish finally, after using it for many years.
My "large archives" c64 downloads site has been updated. At least some of the most important archives on it. That adds 10 years of new updates of The Digital Dungeon or HVSC SID collection. Please find the files here:
And most notably, there is my "ai64_extractor", that I use to extract C64 stuff from FTP sites to make them available for download. It has reached a public repository on GitHub, so that you can create your own archives, without waiting for me to publish new versions of this tool.
Please read on for more info on these two updates.
I've been reading Pine manual when found some interesting recommendations. So much interesting at time of writing, 1998 as of today in 2020 . Especially in today's world of privacy (or lack of thereof).
I'll quote a few things from Pine (Alpine) manual. My point is that people keep mails forever and I don't want my mails to stay in your mailbox forever. There is a period after they are not relevant. And that's very short for most of my e-mails. Your e-mails too. Consider deleting them and clearing Trash (referred as expunge in the article below).
I've published new improvements for render(myMap) tool, my way of mapping OpenStreetMap using printed papers. Changes improve readabilty. (We might be getting older..) Please read on for list of new changes!
I've added several new features to my OpenStreetMap printing tool, called render(myMap), but never mentioned it in this blog before. You can find some info in my references page or read on.
For best results from my bookscanner, I started using the DjVu format, which is designed for scanned books. I've collected a lot of useful information, so I decided to publish that as a small info website, in Hungarian: www.djvu.hu
Exisitng editors for text data DjVu files are quite limited, like for example DjVuSmooth. So I've implemented a new editor in JavaScript, that allows editing both the strucutre of the text (paragraphs, lines, words,...) and the coordinates of the text boxes by simply dragging with the mouse, features like create, delete, merge are also available.
There are many challenges with my DIY bookscanner. I plan to document them sometime... The biggest modification was to replace the plexi glass with the top part of a scanner, because the plexi was very much scratched after a few books. Spreading the light with a semi-transparent cover near to the lamp was also necessary.
Most annoying of all problems was the barrel distortion of the camera. This made the whole equipment no competition to the flatbed scans of old books that are already scanned, that I also plan to scan to improve quality.
I've added some improvements to the openstretmap.hu website:
And of some minor improvements, mainly in usabilty of search box, and updated street autocomplete database.
