I'm surprised that no one brought this up here yet, so I will do albeit a little late  :D

Simon Aarons found out that Google Pixel's built-in cropping tool "Markup" does not properly remove cropped data from PNG images. What happens if you crop down to only 25% of the image? Well the other 75% of the image are not cropped, are not erased, the data remains in the .png file. Only the space needed for the 25% is overwritten in the file. If you shared this image, it's possible to recover some of this 75% data that was supposed to be deleted.

That's not all. It turned out, Microsoft's Windows cropping tool commits the exact same bug. God knows if this was intentional and how many sensitive images are out there now.

How did people not notice the image size not being reduced? At least Screenshot Captor shows the size in the info bar at the bottom :)

Setting up Wi-Fi the proper way is like science in itself. Before you get to drown in actually technical details, you'll first drown in untechnical and superficial "troubleshooting" articles written for the average Joe, trying to find worthy information. Well and last time I got to the details my head began to boil... it's just way too much.
A couple quick tips though:
  • As @Shades correctly pointed out, make sure all your channels are spaced out. Any channels in between will cause interference onto neighbouring frequencies.
  • Make sure to disable 802.11b/g if you're not using them. Especially leaving -b enabled might cause nasty fallbacks onto that slow protocol. I've once helped a person who had 'random 1-2s lags every 15min or so' who lived next to a busy street
  • Optimize beacon intervals etc. to not obstruct the air time. iirc dd-wrt/openwrt wikis had good technical explanations
  • Moar signal strength is not always better. It should be as strong as is needed for a stable signal between transponder and receiver. If A -> B always succeeds, but B -> A has trouble, you can increase signal strength on A all you want, just needlessly extending the radius of A's signal (and causing interference to neighbours).
If you want some general advice and success stories, look for Conference AP setups people. They've seen it all.

Living Room / Youtube will hide dislike counts under all videos
« on: November 13, 2021, 07:31 AM »
A couple days ago, Youtube announced it will remove the dislike counts under videos, citing few reasons (or excuses). You can listen to the announcement video here: [3:02]
In December they'll also restrict API access to dislike counts, with special treatment of select applicants (source: email).

Today, co-founder of Youtube, Jawed Karim commented under that video criticising the change:
Matt doesn't look excited because he knows it's the wrong decision.

Moreover, after 16 years of inactivity he changed the description of the famous first ever public video on Youtube "Me at the zoo" now featuring these lines (if memory serves me right, it never had a description):
When every YouTuber agrees that removing dislikes is a stupid idea, it probably is. Try again, YouTube 🤦‍♂️

Note: The commenter "A K" is not entirely wrong. Jawed's comment was near the very top shortly after posting. Now 3 hours in, it's hidden quite deep under "more comments". Had I not known of its existance, I'd not have found it again.

I totally disagree with the removal of dislike counts. Now whether you like it or not, but the trend started with Justin Bieber's "Baby" in 2010 and it was hilarious for those participating in the culture at the time. Though soon this entire list will be historical: Last but not least the curious case of sympathy with the official White House channel.
No, the actual reasons for me as a viewer are practical. Once you step outside of your subscription list (something YT too tries to abolish), like searching for a video to resolve a problem - the like/dislike ratio becomes a very helpful tool to not waste your time on absolute dumpster fire of poor/spam videos. Many desktop users have been using browser extensions to display that ratio under thumbnails.
Google's sole motive is probably their 'engagement' or viewing duration metric. To me its wasted time spent on an unhelpful/misleading video, to them it's monetizable time when they can insert more adverts. If it is about nicer human interaction for them... well comments are still there by default. People are people and hiding the dislike button will not remove negative commentary per se.

The channel owners always have had these options:
  • Disable likes & dislikes
  • Disable comments
Instead of adding another option to that list (only disable dislikes), Youtube made it mandatory for all. They must've really wanted it not to be optional.
What do you think?

Site/Forum Features / Forum Digests are sent even when empty
« on: March 15, 2021, 07:00 PM »
Hi, it's been a while.
I enabled "For topics and boards I've requested notification on, notify me: [Daily]" in my profile and noticed that this also sends a totally empty e-mail when nothing has happened. This seems like an oddity of this forum software? On other boards I've visited, this usually means "send me notification updates at most once per day when something happened"  :huh:

Now I've set it to just "instantly", that's gotta do it then  ;D Forum - Daily Digest

Quick answer (on my phone currently):
From my perspective the transparency capture used to work and at some point it stopped functioning properly (pretty sure my fault, changing settings etc); but the window is in the middle of the screen and there was plenty of space in all directions yet the window is moved when borders (dis-)appear.
I will double-check all settings tomorrow and test my settings on a clean SC install in parallel.
Thank you guys for the quick replies!
