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.

Lensset - add vintage manual lens data to photos EXIF (shell script)

Posted by: Ferenc Veres on August 1, 2021 09:31:19 AM +00:00
Linux

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.

  • Shows or sets lens data in EXIF
  • Best used with old manual lenses that do not set the EXIF data.
  • Requires Exiv2 to manipulate EXIF!

 

C64 downloads site (and converter script) updated

Posted by: Ferenc Veres on April 6, 2021 04:23:47 PM +00:00
Commodore 64

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:

C64 XLFiles

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.

Thoughts about e-mail - in 2020

Posted by: Ferenc Veres on January 3, 2020 02:38:18 PM +00:00

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).

New info site for DjVu document format - Hungarian

Posted by: Ferenc Veres on April 16, 2014 08:19:28 PM +00:00
DIY Book Scanner

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

WebDjVuTextEd - online DjVu text layer editor

Posted by: Ferenc Veres on April 9, 2014 10:35:51 PM +00:00
DIY Book Scanner

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.

DIY bookscanner and correcting barrel distortion

Posted by: Ferenc Veres on December 22, 2013 10:27:47 PM +00:00
DIY Book Scanner

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.

OpenStreetMap.hu business card and website news

I've added some improvements to the openstretmap.hu website:

  • PlanetPlanet news aggregator
  • Ability to search multiple POIs (e.g. bank & atm, or when shop type does not matter, you just need some food)
  • Added a name-less business card created by a professional designer
  • Coordinates supported in search box

And of some minor improvements, mainly in usabilty of search box, and updated street autocomplete database.
