Peace and Justice history for 8/3
One snip today; there is more on the page. But this entry falls into today’s Republicans lie narrative:
| August 3, 1981 |
 | Nearly 13,000 of the nation’s 17,500 air traffic controllers, members of the Professional Air Traffic Controllers Organization (PATCO), went on strike. |
| After six months of negotiations with PATCO President Robert Poli, the Federal Aviation Administration (FAA) had offered less than 10% of what the union had sought. Due to the stressful nature of their jobs, managing the nation’s ever-increasing volume of airport landings and take-offs without up-to-date equipment, they had asked for a shorter workweek, an increase in pay and retirement after 20 years. 95% of PATCO members rejected the FAA’s final offer. The union had endorsed Ronald Reagan for president in 1980 (one of very few to do so), but President Reagan said they were violating U.S. law banning strikes by federal workers, and would all be terminated unless they returned to work within 48 hours. |
| A Reagan Letter to Robert Poli, PATCO (October. 20, 1980) | |
| Dear Mr. Poli: I have been briefed by members of my staff as to the deplorable state of our nation’s air traffic control system. They have told me that too few people working unreasonable hours with obsolete equipment has placed the nation’s air travellers in unwarranted danger. In an area so clearly related to public safety the Carter administration has failed to act responsibly. You can rest assured that if I am elected President, I will take whatever steps are necessary to provide our air traffic controllers with the most modern equipment available and to adjust staff levels and work days so that they are commensurate with achieving a maximum degree of public safety…. I pledge to you that my administration will work very closely with you to bring about a spirit of cooperation between the President and the air traffic controllers. Sincerely, Ronald Reagan | |

How to strip metadata from your files
https://getsession.org/blog/how-to-strip-metadata-from-your-files
You are being sold with every email, every picture, every blog post, every Instagram post, every thing you put on X or Facebook, you are the cash cow these companies want to milk. I have been taking steps for years to reduce how much these businesses can strip mine my stuff data about me. Here is a program I like, and here is a free tutorial on how to remove a lot of the metadata out of your images and files. I recently realized how much information about myself I include in messages, so I looked into this program by Sessions. Hugs. Scottie

Metadata is a big deal — especially for people who are trying to protect their online privacy. For any files on your computer, there is probably a bunch of metadata about the file — such as location data, when the file was created, when it was last changed, or even what device created the file. If you ever give that file to someone else (or upload it to the internet), the file’s metadata will be transferred as well — which means they can see all that info.
There are plenty of reasons you might want to share a file without wanting to share the metadata as well — such as preserving your privacy or anonymity. To do that, you’ll want to strip the file’s metadata. Stripping metadata from files removes all that extra information and leaves you with just the information in the file itself. Some messengers—like Session—strip metadata from your image files when you attach them to a message. This is because they can contain sensitive EXIF data, which contains device and location information. Other file types—like MP3s—might have less sensitive metadata (such as a song name or artist) which won’t be stripped.
However, if you want to be sure, you can always manually strip the metadata from your files. Here’s how!
How to remove metadata from files using Windows
Scrubbing your files on Windows is relatively easy, you can do so directly in the File Explorer without relying on any third party software.
Locate the file you want to strip in Explorer
Right click on the file and select Properties
Select the Details tab to see the associated metadata
Click Remove Properties and Personal Information
Select the metadata you want to remove
Select to either Create a copy (if you want to preserve the original) or Remove properties from this file
Click OK
Ta-da! Metadata removed, now you can safely share the file without extra personal information being attached.
How to remove metadata from files using macOS
Unfortunately things aren’t as simple on macOS. There’s no catch-all option for all file types, and you can only remove specific kinds of data. For images, you can remove location data using macOS’s built-in Preview application.
Open the image in Preview
Hit CMD + i to display the image’s metadata
Navigate to the Info tab (circle with an ‘i’ inside it)
Click on GPS to see the location metadata
Click Remove Location Info to remove the GPS information stored in the image
For anything more thorough than this (or any file type other than images) you’ll need to use third-party software, such as Acrobat Pro for PDFs.
How to remove metadata from files using Linux
Thankfully, things are much easier on Linux! Note: Instructions may be different depending on your distro.
If you’re using a Debian-based system (such as Ubuntu), you can install MAT (which comes pre-packaged) using this command:
$ sudo apt-get install matYou can then launch the MAT GUI using this:
$ mat-guiAdd the file you want to strip to MAT by clicking the Add icon in the top navigation bar
Once the file is added, click Check to scan for metadata
If metadata is detected, MAT will mark the file as ‘Dirty’, you can double click the file to see what metadata has been detected
Click Clean to strip the metadata from the file
Simple as that!
Keep your files safe
Stripping metadata from your files before you share them is a good idea — especially if you’re going to upload them somewhere public on the internet. If you want to be certain that the files you send are completely metadata free (even to the people you send them to) — make sure to strip them first! To ensure your files stay private, it’s also important to consider how and where you store your files. Make sure you’re encrypting your hard drives, and be careful about what Cloud storage providers you use and what upload.
These days, it’s a normal everyday thing to share files on messaging apps and social media — but it’s important to be mindful about what exactly you’re sharing. Once those files hit the internet — they could end up anywhere!

New feature spotted in brightest gamma-ray burst of all time
July 28, 2024 Evrim Yazgin
NASA’s Fermi Telescope has revealed new details about the brightest of all time gamma-ray burst which may help explain these extreme and mysterious cosmic events.
Gamma-ray bursts (GRBs) usually last less than a second. They originate from the dense remains of a dead giant star’s core, called a neutron star. But what causes neutron stars to release huge amounts of energy in the form of gamma radiation is still a mystery.
In October 2022, astronomers detected the largest gamma-ray burst ever seen – GRB 221009A. It came from a supernova about 2.4 billion light years away. The event had an intensity at least 10 times greater than any other GRB detected. It was dubbed the BOAT, for brightest of all time.
Now, analysis of the data from that event has revealed the first emission line which can be confidently identified in 50 years of studying GRBs.
The new analysis is published in Science.
Emission lines are created when matter interacts with light. Energy from the light is absorbed and reemitted in ways characteristic to the chemical make up of the matter which is interacting with it.
When the light reaches Earth and is spread out like a rainbow in a spectrum, the absorption and emission lines appear. Emission lines appear as dimmer or even black lines in the spectrum, whereas emission lines are brighter features.
At higher energies, these features in the spectrum can reveal processes between subatomic particles such as matter and anti-matter annihilation which can produces gamma rays.
“While some previous studies have reported possible evidence for absorption and emission features in other GRBs, subsequent scrutiny revealed that all of these could just be statistical fluctuations,” says coauthor Om Sharan Salafia at the Italian National Institute of Astrophysics Brera Observatory in Milan. “What we see in the BOAT is different.”
The emission line appeared almost 5 minutes after the burst was detected. It lasted about 40 seconds.
It peaked at 12 million electron volts of energy – millions of times more energetic than light in the visible spectrum.
The astronomers believe the emission line was caused by the annihilation of electrons and their anti-matter counterparts, positrons. If their interpretation is correct, it means the particles would have to have been moving toward Earth at 99.9% the speed of light.
“After decades of studying these incredible cosmic explosions, we still don’t understand the details of how these jets work,” says Elizabeth Hays, Fermi project scientist at NASA’s Goddard Space Flight Center in the US. “Finding clues like this remarkable emission line will help scientists investigate this extreme environment more deeply.”

Dems, Non-Trumpers: Going on Offense in Pushing Back Against Trump’s Lies and Missteps
I have followed Gronda for a long time, before she took her long break. But she is back and her writtings while in debth and a bit long are so very interesting and well researched that they are more than worth the time to read. I love them. I hope everyone here will. Hugs. Scottie
