Photoshop Experts Using Photoshop 1.0

Photoshop just turned 25.* Even in its first version, the program had impressive photo-editing features. Fast forward two and a half decades, and CreativeLive asked some modern-day pros to sit down with the original program, and they're delightfully stumped:

Now, a little analysis of what's happening here. As you've seen above, one of the biggest problems for modern users was the lack of multiple Undo actions. This is because modern Photoshop versions (since the early 2000s, I believe) have had a History Panel, essentially a large stack of Undo-able actions, organized and logged nicely. Another big "missing feature" is live preview (moving sliders and seeing the image adjust on the fly), which likely wasn't possible given the limitations of the hardware and its operating system at the time—this was why Photoshoppers typically saved the file after every major edit, to myfile-1, myfile-2, until the puny hard drive was full.

Oh yeah, and there were no layers; layers have been fundamental to how Photoshop has been used for decades. The final area that's really rough is how Photoshop 1.0 dealt with typography; it rendered the text straight into the image, chunky pixel edges and all. Ugh. But still...this was a professional tool (and an amazing one) 25 years ago, and it blew our minds at the time. On the flip side, it's impressive to see how similar many of the control panels are to the original, even so much later. Decades of refinement have not erased the original character of Photoshop.

* = Technically, the first version of Photoshop shipped in limited quantities in 1989, bundled with some scanners. Adobe seems to have picked 1990 as its first year, likely because it was broadly available as a standalone program at that point.

Arctic Temperatures are Rising So Fast, They're Confusing the Hell Out of Computers

This past year was a brutal one for northern Alaska, which saw temperatures that soared above what was normal month after month. But you wouldn't know that by looking at the numbers from the weather station at Utqiaġvik, Alaska. That's because the recent heat was so unusual for the area that computers marked the data as incorrect and failed to report it for the entirety of 2017, leaving a hole in the records of the Climate Monitoring group at the National Centers for Environmental Information (NCEI), according to the Huffington Post.

The weather station in the northernmost tip of Alaska has been measuring temperatures for nearly a century. A computer system there is programed to recognize if the data has been influenced by artificial forces: Perhaps one of the instruments isn't working correctly, or something is making the immediate area unnaturally hot or cold. In these cases, the computer edits out the anomalies so they don't affect the rest of the data.

But climate change has complicated this failsafe. Temperatures have been so abnormally high that the Utqiaġvik station erroneously removed all its data for 2017 and part of 2016. A look at the region's weather history explains why the computers might have sensed a mistake: The average yearly temperature for the era between 2000 and 2017 has gone up by 1.9°F from that of the era between 1979 and 1999. Break it down by month and the numbers are even more alarming: The average temperature increase is 7.8°F for October, 6.9°F for November, and 4.7°F for December.

"In the context of a changing climate, the Arctic is changing more rapidly than the rest of the planet," Deke Arndt, chief of NOAA's Climate Monitoring Branch, wrote for climate.gov. The higher temperatures rise, the faster Arctic sea ice melts. Arctic sea ice acts as a mirror that reflects the Sun's rays back into space, and without that barrier, the sea absorbs more heat from the Sun and speeds up the warming process. “Utqiaġvik, as one of a precious few fairly long-term observing sites in the American Arctic, is often referenced as an embodiment of rapid Arctic change,” Arndt wrote.

As temperatures continue to grow faster than computers are used to, scientists will have to adjust their algorithms in response. The team at NCEI plans to have the Utqiaġvik station ready to record our changing climate once again within the next few months.

Big Questions
What Could the Repeal of Net Neutrality Mean for Internet Users?

What could the repeal of net neutrality mean for the average American internet user?

Zouhair Belkoura:

The imminent repeal of net neutrality could have implications for Americans beyond the Internet’s stratification, increased costs to consumers, and hindered access to content for all. Net neutrality’s repeal is a threat to the Internet’s democracy—the greatest information equalizer of our time.

With net neutrality’s repeal, ISPs could be selective about the content and pricing packages they make available. Portugal is a good example of what a country looks like without net neutrality

What people may not realize is that a repeal of net neutrality would also give ISPs the ability to throttle people’s Internet traffic. Customers won’t likely have visibility into what traffic is being throttled, and it could substantially slow down people’s Internet connections.

What happens when this type of friction is introduced to the system? The Internet—the greatest collective trove of information in the world—could gradually be starved. People who experience slower Internet speeds may get frustrated and stop seeking out their favorite sites. People may also lose the ability to make choices about the content they want to see and the knowledge they seek.

Inflated pricing, less access to knowledge, and slower connections aren’t the only impact a net neutrality repeal might have. People’s personal privacy and corporations’ security may suffer, too. Many people use virtual private networks to protect their privacy. VPNs keep people’s Internet browsing activities invisible to their ISPs and others who may track them. They also help them obscure their location and encrypt online transactions to keep personal data secure. When people have the privacy that VPNs afford, they can access information freely without worrying about being watched, judged, or having their browsing activity bought and sold by third-party advertisers.

Virtual private networks are also a vital tool for businesses that want to keep their company data private and secure. Employees are often required by their employers to connect to a VPN whenever they are offsite and working remotely.

Even the best VPNs can slow down individuals' Internet connections, because they create an encrypted tunnel to protect and secure personal data. If people want to protect their personal privacy or company’s security with a VPN [they] also must contend with ISP throttling; it’s conceivable that net neutrality’s repeal could undermine people’s freedom to protect their online safety. It could also render the protection a VPN offers to individuals and companies obsolete.

Speed has always been a defining characteristic of the Internet’s accessibility and its power. Net neutrality’s repeal promises to subvert this trait. It would compromise both people's and companies’ ability to secure their personal data and keep their browsing and purchasing activities private. When people don’t have privacy, they can’t feel safe. When they don’t feel safe, they can’t live freely. That’s not a world anyone, let alone Americans, want to live in.
