Total Solar Eclipse To Hit The Earth: How To Comfortably View It
Solar: If you had not heard it, an important eclipse will soon occur. The United States has not had a total visible solar eclipse from coast to coast (from the Pacific to the Atlantic) since 1918 – so we thought we would give some retina-safe options to see the eclipse on August 21, 2017.
And to be clear, safety is paramount. Repeat after me:
- Do not watch any phase of the eclipse with your naked eye.
- Keep in mind that conventional sunglasses will not protect your eyes.
- Spectators of cheap, unsecured eclipses that are sold will not protect their eyes, either.
We have drawn those points from NASA’s safety tips to prevent eye injuries during an eclipse, and you should read all those suggestions.
When it comes to buying eclipse glasses, the emptor warning is applied – your vision is on the line, it is very important to know that you are getting the viewers with the proper protection.
To do this, we have used NASA guidelines to create our recommendations for the eclipse display team. The most important rule while buying is that there are specific manufacturers and sellers that sell certified glasses / spectators that comply with the international standard ISO 12312-2 (that is what you will need to be protected from the sun while staring). The American Astronomical Society has an excellent summary of manufacturers, vendors and retail chains where you can get sunscreen equipment, and that’s more information on our list.
Cheap and easy: paper glasses ($ 1 and more)
We have seen them before, they are paper frames that look like old school 3D glasses, but instead of the old cyan / red combo, they are equipped with solar display material. You can purchase these in packages for around a dollar per pair, making a great choice for families, teachers or organizations hoping to provide large amounts on the cheap. Again, make sure you are getting one made by or approved by the manufacturers AAS list.
Do you have a pair that puts around your plan to reuse? If they are wrinkled, cracked, or over 3 years old, litter. They are dangerous and may not provide sufficient protection.
Sturdier but still cheap: Plastic glasses / cardboard spectators ($ 10 – $ 20)
We have seen somewhat tougher options, such as plastic frames that look like sunglasses, and folding carton viewers. This is a great option if you want your glasses to last a little longer, but again, make sure you are buying from a company that sources your material from the AAS list (eg: Celestron viewers often use the Solar display material from American Optical Paper).
The ‘maybe I have this in my garage’ option: welding shields / glasses (free- $ 20)
This is complicated because while you may have a pair of welding goggles in your garage, they have to be at least 14 or more dark shade to enough, according to NASA. You can also pick up a simple piece of 14+ shade glass from a welder at a supply store and keep it between your eyes and the sun to see the eclipse. In shadow 14 and above, they are dark enough to meet the transmittance requirements for ISO 12312-2: 2015. The thing is, most basic welding glasses are not as heavy – and if it is not Sure, it’s not worth taking the risk. Trust us.
Get a closer look at a reasonable price: Solar Display Binoculars ($ 20- $ 80)
I’ve never heard of sun-vision binoculars, but it’s a very good idea. The use of binoculars with approved ISO sunscreens, such as this Celestron model, allows you to get a slightly magnified look in the sun. You will have to exercise a little caution putting them in and out of your face, but if you are a solar enthusiast, this could be a great option. (Note: Never use standard binoculars to look at the Sun. If you have ever had a magnifying glass on an ant on a sunny day … well, imagine the ant is your retina.
Going eclipse gonzo: A telescope with sunscreen lens (Price: potentially astronomical)
If you already have a telescope, you’re probably more space enthusiast than I am, so I might be repeating what you already know. But you can buy sunscreens for your telescope that allow you to get a closer look without damaging your eyes. Some of these filters are relatively affordable, and some can be very expensive, allowing you to see the sun at very specific wavelengths. (Again, never see the sun through a telescope without the right equipment.
WhatsApp Adds New Feature “Dismiss As Admin” For Group Admins
Facebook’s popular messaging application WhatsApp has started to implement a new feature that allows an administrator to ‘fire’ a co-administrator in a group chat. The ‘Dismiss as administrator’ feature allows an administrator to remove other administrators from the publication, without first removing them from the group and then re-adding them as normal members of the group.
The ‘Dismiss as administrator‘ feature of WhatsApp is now available in the beta version of WhatsApp for Android and is under development in iOS. However, the global deployment of this new feature remains currently uncertain. According to WABetaInfo, a fan site that tests the new features of WhatsApp early, the new option allows one administrator to discard another without removing it from the group.
“Currently, WhatsApp is developing this feature for iOS and will soon be available to all users. It is already enabled in the latest beta version of WhatsApp Google Play for Android 2.18.12,” the report added. At this time, when an administrator wants to eliminate a fellow administrator of the publication, first the corresponding administrator of the group must be directly deleted and then added again.
Also, WhatsApp can grant group administrators more powers in which they could restrict other members to send text messages, photographs, videos, GIFs, documents or voice messages. The application has sent the “Restricted Groups” setting through the Google Play Beta Program in version 2.17.430. Once restricted, other members will just have to read their messages and will not be able to respond or post anything in the group.
WhatsApp is used by 1 billion plus people around the world. The messaging application is a key tool for communications and commerce in many countries.

Google Set To Prepare Developers For 2018
The move is meant to prepare for a future version of Android that will only support 64-bit applications, and Google is billing it as an improvement to the security performance of the platform as a whole. Google’s announcement included a final detail about a new practice that will take effect in early 2018. This statement also indicates that Android P, expected to arrive in September 2018, probably rules out the compatibility with the slowest 32-bit application and will join IOS as another mobile OS platform with the latest processing support.
The target API level is technically defined as the version of the operating system with which an application was tested; but in more practical terms, it is used to define a set of behaviors that an application expects from the operating system. The second season has 89p, it is reduced from £ 4.59. That’s not all because the company will also require application developers to point to the Android Oreo programming interface.
As of November 2018, the same requirement applies to the update of existing applications. After years of fighting with Apple and Google over the rules for having a video store on Apple TV and Android TV today, you can now find an Amazon Prime Video on Android TV and Apple TV. The new configuration works even when the screen is off on devices that always support the listening mode. Recall that there was a time when Android watches were labeled as commercially unsuccessful by certain analysts. After Google announced that they would get support for YouTube on their FireTV and Echo Show hardware, it seems that Amazon is slowly changing, and this is a good step for customers, at least if they could install the application. The other big change comes in 2019. Most Android devices work with ARM-based chips. Android itself added 64-bit support with 5.0 Lollipop in 2014. This can result in much better performance. Google has now set clear guidelines for all developers who want to make applications for Play Store advance. Developers do not need to make any changes themselves, but metadata should help verify the authenticity of the application.
