Science

  • Springer Link: a wealth of science related books and articles

Today I received a list of free PDFs links from the Springer editorial. I downloaded several interesting sounding books and then visited the site a bit. I noticed it had a lot of free ‘Open Access’ papers which means you can read / download PDFs of them. Here’s the site: Springer Link website

Wordpress fundamental plugins

While looking into Wordpress I find several plugins that seem to be ‘core’ plugins. These are:

  • Jetpack - [web] “Safer. Faster. More traffic. Security, performance, and marketing tools made for WordPress sites by the WordPress experts”. This is the product tour web page
  • VaultPress - [web] Wordpress backup and security service. “VaultPress protects you from the most common — and most serious — security threats.”
  • Akismet - [web] Filter spam from sites.

Theme inspiration for green themes

Markdown, file based CMSs

I wanted a to host this blog with some requirements:

  • markdown format - I want to have all my posts as .md files
  • minimalist pretty Theme
  • simple setup

I ended up using Github pages (a.k.a Jekyll). I found an open source theme I liked and I’m using that (plainwhite). In the process I found a couple of others I liked. I leave here my list:

  • CirculateCMS - A PHP based, very minimal CMS. [web]
  • Textpattern - Another PHP based CMS. I really liked the webpage. I might use this for another project [web]
  • Grav - This was another PHP based one I had seen in the paste. Still like it. [web]
  • Ghost - This is really nice but was too complicated for what I wanted [web] [thems for ghost]. One I particularly liked [blog styles]

Max Piantoni: interesting artist / coder

I recently came accross a [YouTube video] of someone who recreated a little animation that is shown on an Apple //c on an 80’s movie ‘A View To a Kill’ (here’s the [github repo] with the actual code). His name is Max Piantoni. So I visited his site and he does some interesting crazy projects. Checkout his site to see more fun stuff or follow him on [twitter].

Online Petscii editor for C64

This is an awesome web-based PETSCII editor: petscii editor webapp. Really complete: it allows you to add sprites, much better really that Petmate. unfoctunately there is no source code or repo o downloadable version.

There is another great PETSCII editor: lvlvl.com. This one is created by @uniquename654 twitter user.

Sony a6000, a6300, a6500, a6400, a6100 and a6600 comparison

Sony a6000 lineup

I’ve been looking into replacing my Sony a6000 with a newer model so I wanted to see what the current line of Sony a6000 looked like in 2020. After watching a couple of videos I found a really good onw [YouTube] which really covers all 6 available cameras. I’ll write my conclusions here to save me time when I finally get to making the purchase:

  • The chronological order is: a6000, a6300, a6500, a6400, a6100, a6600
  • All models except the a6000 shoot 4k video, 120 frames/sec FullHD, have 425 auto-focus points and have a mic in plug.
  • The a6400, a6100 and a6600 have the new flipup screen
  • All models except the a6000 and a6100 have a better built (and weather proof) body
  • All models except the a6600 have a built-in flash
  • The rest of the features I show in a Matrix. They are: flip screen, double resolution viewfinder, no overheating when recordin more than 30min video, better looking menues, lareger battery, image stabilization for the sensor, a new and improved processor and better quality colors.

Conclusions:

  • If you have an a6000 you should update to an a6600, a6400 or a6100 in that order.
  • They are all awesome camaras, its just a matter of price. For me I’ll probably settle on either the a6100 or a6400.
  • The a6600 at the current pricepoint is the best of best at that market. The a6400 is the best bang for the buck.
  • See all details here: [YouTube] and here a6100 [YouTube]
  • The videos by the author of the previous review is really good and has another video where he shows his favorite lenses for the a6x0 series [YouTube]. In this video he recommends the Sigma 16mm prime lens (Sigma 16mm f/1.4 DC DN Contemporary Lens for Sony E).
