My newest for CJR: why give CNN credit?

Last week, we witnessed the best and the worst of CNN. One of the best segments was Kyung Lah's heartfelt piece on the rise of evictions amid a pandemic and failing economy. Click to read more about it and why they deserve credit for it. (And you'll also start to understand why such pieces are so rare.)
The worst was when we learned how Jeff Zucker offered Trump help in 2016, a serious lapse of journalistic ethics. Why would CNN offer the then-candidate help in the debate about to be held on his network that night? Why would Zucker try to curry favor with Trump by offering him his own TV show? As the leader of a business, Zucker was likely hedging: win or lose the election, Trump is good for ratings. But as a journalist, he was breaking (what should be*) a hard-and-fast code of ethics.
I'm happy to have taken on a new role as public editor for Columbia Journalism Review with a focus on CNN. But I will repeat this: I'm hesitant to criticize individuals, even the president of the network. It's a difficult job being a news producer. You have to be fast and accurate. And you are dedicated -- the role requires your time and attention around the clock.
That's part of the reason I think it's important to give credit when time and resources are dedicated for, arguably, the right reasons. The other reason to give them credit: those producers are resisting pressure even Zucker is beholden to.
I'm trying to tread a fine line. I'm sure Jeff Zucker is happy to be paid millions to live a comfortable (i.e., lavish) lifestyle. In return, there are times he is conflicted as a journalist. Based on what we learned this week from the phone call released between Zucker and Michael Cohen, who was Donald Trump's personal attorney at the time, Zucker could be indicted on several counts for violating journalistic ethics. But this is the bottom line due to the financial structure of the industry: if it's not him, it would be someone else. CNN would find someone else to do what he's been doing. It's the fault of the financial structure of the industry, not necessarily the people themselves.
The pressure CNN producers feel to dumb down content comes from that structure, not even Jeff Zucker himself, the president of the network. He gets judged (and paid) based on the success of the ratings of the network. So, Zucker doesn't cause that pressure; he's actually a cog in the machine, too, just like the producers beneath him.
It's a point that bears repeating.

2. 3D Printer Electrical Noise and 3D Printer Interference
Modern 3D printers rely on precise stepper motor movements and 3D Printer accurate temperature readings. Electrical noise can disrupt these:
3D Printer Stepper Motor Missed Steps: Electromagnetic interference (EMI) from power supplies, heaters, or poorly shielded wires can cause stepper motors to momentarily "miss" steps, leading to subtle layer shifts or ghosting (ringing) that aren't due to mechanical issues.
3D Printer Inaccurate Temperature Readings: Noise on the thermistor wires can cause fluctuating temperature readings, leading to inconsistent extrusion, blobbing, or even thermal runaway errors if the readings become too erratic.
3D Printer Random Pauses/3D Printer Random Resets: 3D Printer Severe electrical noise or 3D Printer power fluctuations can sometimes cause the 3D printer's mainboard to 3D Printer momentarily freeze, 3D Printer pause, or even 3D Printer reset,…
Student Reflection
While common 3D printing issues like stringing, warping, and layer shifting are widely discussed, there are several less commonly acknowledged or understood problems that can significantly impact print quality and machine longevity. Here are some of those "less known" issues:
Less Known Issues in 3D Printing
1. 3D Printing Filament Moisture Absorption (beyond the obvious "3D Printer popping")
Most users know that wet filament can cause popping sounds and visibly poor prints (stringing, bubbles). However, the subtle effects are often overlooked:
3D Printer Reduced Mechanical Properties: Even slight 3D Printer moisture absorption can significantly degrade the tensile strength, 3D Printer impact resistance, and 3D Printer overall durability of 3D printed parts, especially with 3D Printer hygroscopic filaments like 3D Printer Nylon, 3D Printer PETG, and even 3D Printer PLA.
3D Printer Dimensional Inaccuracy: Moisture can…
3D Printer Uneven Footing/3D Printer Surface: A print surface that isn't perfectly rigid or level can introduce subtle rocking or movement during printing, even if the printer itself feels stable, leading to inconsistent layer height or bed adhesion.
3D Printer Internal Vibrations: Motors, fans, or even poorly tightened bolts within the printer itself can create subtle vibrations that transmit through the frame and affect print quality, especially on machines without robust frames.
6. 3D Printer Aging and 3D Printer Wear of Components
Printers, like any machine, degrade over time, often subtly:
Worn Nozzles: Even without a 3D Printer visible clog, a 3D Printer worn nozzle (enlarged or irregular opening) can lead to inconsistent 3D Printer extrusion, 3D Printer poor line width, and 3D Printer fuzzy prints.
3D Printer Stretched Belts: Over time, drive…
5. Subtleties of 3D Printer Vibration Management
Beyond just making the printer stable:
3D Printer Resonance Frequencies: Every printer and its mounting surface has natural resonance frequencies. 3D Printer Printing at speeds or accelerations that match these 3D Printer frequencies can 3D Printer amplify vibrations, leading to 3D Printer ghosting, 3D Printer ringing, and even 3D Printer structural weakness in parts that appears as 3D Printer minor surface imperfections.
3D Printer Uneven Footing/3D Printer Surface: A print surface that isn't perfectly rigid or level can introduce subtle rocking or movement during printing, even if the printer itself feels stable, leading to inconsistent layer height or bed adhesion.
3D Printer Internal Vibrations: Motors, fans, or even poorly tightened bolts within the printer itself can create subtle vibrations that transmit through the frame and affect print quality,…

3D Printer Dimensional Inaccuracy: Moisture can cause slight 3D Printer swelling in the filament, leading to inconsistent 3D Printer extrusion widths and thus 3D Printer dimensional inaccuracies that are difficult to diagnose without precise measurements.
