Elon Musk reveals how SpaceX will address light pollution caused by Starlink satellites

28 Apr

Following the successful launch of its Starlink 6 batch of satellites last week, SpaceX CEO Elon Musk tweeted out a few details about night sky light pollution caused by these low Earth orbit satellites and the company’s plans to address this issue.

According to the tweet, SpaceX is taking ‘some key steps to reduce satellite brightness,’ something that Musk says should make them ‘much less noticeable during orbit raise.’ This change involves adjusting the solar panel angle, according to the tweet, plus there will be a new addition to the satellites starting with the Starlink 9 launch: sunshades.

It’s unclear how drastically these changes will reduce the brightness of its satellites, but the move underscores SpaceX’s efforts to address concerns about light pollution caused by these small satellites.

The Starlink initiative aims to launch thousands of small low-Earth orbit satellites that will beam Internet service to the ground, providing high-speed broadband access in places where it’s unavailable from terrestrial providers, or where only slow and expensive options are available. Musk said in a tweet following the Starlink 6 launch that the company plans to start a private beta of the Starlink service in around three months.

Renewed attention to the issue of light pollution caused by low-Earth orbit satellites was spurred with the launch of NASA’s Satellite Streak Watcher project in early March. In explaining the reason for the initiative, the space agency said that the increasing number of these satellites launched into orbit makes things more difficult for astronomers on the ground.

The light pollution caused by these satellites is also a problem for astrophotographers, causing long streaks of light to appear in long-exposure images. Unlike avoiding light pollution from the ground, it’s not possible to head to a ‘dark sky reserve’ or other similar places to avoid light pollution originating from space.

SpaceX hasn’t been ignoring this problem; back in December 2019, the company said that it was experimenting with a new anti-reflective coating that would make the satellites less bright, though it may potentially result in satellite performance problems by causing thermal issues. Based on Musk’s most recent tweet, it seems the company is turning to sunshades as its solution.

With the Starlink 6 satellite launch last week, SpaceX now has 420 of these small satellites in orbit. The company plans to launch a minimum of 12,000 satellites over the coming months, though the figure may exceed 30,000 in the long run. A public beta of the Starlink service will start in the US and Canada in around six months following the private beta, according to Musk’s tweet. It’s still unclear how much the eventual Starlink Internet service will cost.

Nikon updates Capture NX-D, ViewNX-i and Picture Control Utility to address various bugs

20 Mar

Nikon has updated its Capture NX-D, ViewNX-i and Picture Control Utility 2 programs to address multiple bugs and add new features.

Nikon Capture NX-D

Nikon Capture NX-D version 1.5.2 is mainly about fixing various crashes and glitches that would occur when using the app. Below is a thorough rundown of the ten issues that have been fixed, according to the changelog:

  1. The application would crash under some conditions.
  2. If the Specify size option was selected in the batch processing dialog, some time would elapse before the Start button would be available.
  3. Changes to image length in the Convert Files dialog would sometimes not be matched by changes to width.
  4. All changes to NEF/NRW (RAW) pictures made with NEF/NRW + JPEG enabled would be lost when the files were saved in JPEG format.
  5. Batch processing and file conversion could not be resumed once paused.
  6. The application would sometimes fail to launch.
  7. Image artifacts (“noise”) would increase in pictures saved in other formats.
  8. Straighten now functions as intended.
  9. Files saved at an image quality of “99” would be larger than those saved at an image quality of “100”.
  10. Portions of NEF (RAW) images shot with the Z 6 would sometimes not display correctly after the pictures were saved using NEF processing.

Nikon Capture NX-D version 1.5.2 can be downloaded for macOS and Windows computers on Nikon’s website.

Nikon ViewNX-i

Nikon ViewNX-i version 1.3.2 fixes two main issues found in version 1.3.1. The first is an issue that caused files saved at an image quality of 99 to be larger in size than images captured at an image quality of 100. The update also fixes a problem that caused files being saved using ‘Ctrl+S’ to lose or alter the XMP/IPTC information.

Nikon ViewNX-i version 1.3.2 can be downloaded for macOS and Windows computers on Nikon’s website.

Nikon Picture Control Utility

Last up is Picture Control Utility version 2.4.2. This update fixes an issue that caused some NEF images shot with Nikon Z6 cameras to not be displayed properly after the images were saved.

Picture Control Utility version 2.4.2 can be downloaded for macOS and Windows computers on Nikon’s website.

Google rolls out ‘Saturated’ mode to address Pixel 2 XL display issues

10 Nov

The Google Pixel 2 might sport one of the best smartphone cameras around, but when it comes to the display—particularly on the larger XL—model, Google has had nothing but trouble. Reports of everything from burn-in, to blue tint off-axis, to ‘dull’ colors have left the tech giant playing catch up, and today it finally … well… caught up. Or at least it tried.

A promised software update released on Tuesday (and rolling out to all users by the end of the week) addresses the issue of burn-in with some minor tweaks, and adds three total color saturation modes under the phone’s Display settings to hopefully quiet down the complaints about ‘dull’ colors.

Here’s a quick summary of the update in Google’s own words:

This update includes some of the enhancements we posted about on October 26, such as the new Saturated color mode for Pixel 2 and Pixel 2 XL, a fix for the faint clicking noise heard in some Pixel 2s, and other bug and security updates. As we mentioned in our deeper dive, this update also brings planned UI changes which extend the life of the OLED display, including a fade out of the navigation buttons at the bottom of the screen and an update to maximum brightness.

According to Android Central, the updated saturation settings come in three flavors: Natural, Boosted, and Saturated. Natural should provide the most accurate color reproduction; Boosted takes the place of the “Vivid Colors” setting previously available, which boosted saturation by 10%; and, finally, Saturated will put the display in an “unmanaged configuration” that will make colors “more saturated and vibrant, but less accurate,” according to Google’s deep dive on the topic.

Unfortunately, this mode throws away one of the most important things about Android Oreo: color management. In ‘Saturated’ mode, all apps, images and video will first render to sRGB (for now) and then be stretched to the display’s wider color gamut.

This will make for inaccurate colors across the two devices, but there is hope for us color nerds. As Seang Chau, VP of Engineering at Google, says in his blog post: due to color management under the hood in the new OS, “an Android app developer can now make use of the wider Display P3 color gamut precisely for a wider range of colors. Google apps will take advantage of wide colors in the future.” We’re hoping this means that future apps will render either to P3 or straight to a display profile provided by Google, which would allow for saturated colors when appropriate, but not at the cost of accuracy.

Finally, no comment was made on the poor viewing angle of the XL model that introduces a strong blue-tint off-axis (see picture above of the Pixel 2 XL vs the original XL). This can make photos with warmer tones look even more desaturated by shifting toward blue. But while Google was able to address some of its display complaints this week, this seems like a hardware problem that will be difficult to fix via software.

Google may address ‘dull’ colors of Pixel 2 XL display, is investigating burn-in reports

24 Oct

Google’s newly launched Pixel 2 XL smartphone has received some criticism from buyers who claim the POLED display appears ‘dull’ when compared to the vivid OLED displays used by some of Pixel 2 XL’s competition. Google recently commented on the criticism, telling 9to5Google that it will consider releasing a software update that adds more display color options.

“One of our design intents was to achieve a more natural and accurate rendition of colors,” Google said in its statement. For users who want more vivid colors, Google says it has provided an optional setting to increase the saturation by 10%. However, should that prove inadequate, Google says it will, “consider adding more display color options through software if that makes the product better.”

But a ‘dull’ screen isn’t the worst of Google’s Pixel 2 XL display troubles—this week’s news is just getting worse and worse for the handset. Some early adopters claim they are already experiencing burn-in, others claim there are ‘blue tint’ issues, and some reviewers have noticed a ‘graininess’ issue.

Regarding the burn-in issue, Google told The Verge it is “actively investigating” the reports. After all, while muted colors aren’t a concern for some users, rapid burn-in—a problem that causes a potentially permanent ‘ghosting’ image to appear on the screen—could be enough to deter consumers from buying the phone altogether.

Early Pixel 2 XL users are also reporting a distinct blue tint that is visible when looking at the display from an angle. This blue tint issue is said to be most visible when the display’s background is light; a similar problem has been observed with the previously launched LG V30, a handset that features the same panel used in the Pixel 2 XL.

We can indeed confirm the viewing angle issues of the Pixel 2 XL. Here it is pictured next to the original XL (bottom) in our offices. There is a cyanish-green shift accompanied by progressive desaturation as you tilt the phone in any direction in your hand. It’s noticeable at even modest viewing angles. This can particularly make using the Pixel 2’s otherwise phenomenal camera a bit uninspiring: the preview looks noticeably desaturated and greenish if you shoot any angle that doesn’t have the phone directly in front of you.

Finally, reviewers have noted that the Pixel 2 XL’s POLED display has an underlying graininess not shared by the Samsung OLED panel used in the smaller Pixel 2 phone. Ars Technica posted a side-by-side comparison photo of the two phones that highlights the XL’s graininess issue.

It’s safe to say it’s been a rough weekend for Google. We’ll keep you updated as Google addresses each of these issues in turn, and keep an eye out for our own Pixel 2 XL review coming soon!

Inhabitable Nomadic Shelters: Designs Address LA’s Homelessness Crisis

The problem of homelessness is a complex one rooted in gross stratification of wealth, and while addressing it in full means addressing poverty itself, temporary portable housing can save lives in the meantime. Many cities are implementing transitional housing programs that make use of inexpensive, easy to move structures in interstitial urban spaces. The Martin Architecture and Design Workshop (MADWORKSHOP) teamed up with students from the University of Southern California School of Architecture (USC) to come up with some creative examples of these structures.

‘The Homeless Studio’ is an organization aiming to address LA’s homelessness crisis through design. Students built a series of full-scale, inhabitable nomadic shelters ranging from contraptions that fit onto shopping carts to more comfortable structures that wouldn’t be out of place in a tiny house village. Most of the materials were scavenged from around Los Angeles, and the designs had to be collapsible and suitable for a variety of locations.

The results are sometimes more artistic than they are practical – like a hut clad in retail mannequin displays – but in many cases, the interiors are cozy and well-lit by windows and skylights, and one design even has a roof deck.

The aim of actually addressing homelessness didn’t just consist of building a few weird-looking structures and calling it a day. The students worked with city officials, local agencies, artist and activists to come up with a holistic solution in a city where nearly 47,000 people live on the streets. They’re making repeated visits to local agencies like the Skid Row Housing Trust and the Downtown Women’s Center, speaking to people experiencing homelessness to get firsthand information about their needs.

They’ll also be taking the hands-on skills and knowledge they gained through this project and applying it to a larger solution, designing a 30-bed modular shelter for women for Hope of the Valley Rescue Mission in San Fernando Valley. Their efforts over the course will be documented and compiled into a publication set for publishing by the USC School of Architecture in 2017.

Google Search Engine – What is My IP Address?

01 May

Need to find your public IP address? It’s just a Google search away.

For playing online games or accessing particular Internet services, it might prove useful to know your public IP address (the address that other computers / devices on the Internet can use to contact your machine and the address given out when contacting other computers / devices). If you are using an ISP (Internet Service Provider) that provides dynamic IP addresses, this may change every time you go online. And, if you use a proxy server or VPN (virtual private network), displaying your “public” IP address can help ensure you are actually accessing the Internet via the connected service.

Instead of going through computer settings to display your public IP address, finding this information is just a Google search away:…
