The article from The Economist discusses the future of the office in the context of evolving work practices due to the global health crisis. Here are the key points:
Remote Work Surge: The shift to remote work has been accelerated by the necessity to avoid physical gatherings during the health crisis, leading to a significant increase in remote work capabilities.
Productivity Debate: There’s an ongoing debate about whether remote work increases or decreases productivity. Some evidence suggests productivity might even improve with remote setups, though there are concerns about long-term effects on innovation and collaboration.
Office Space: Despite the rise of remote work, physical office spaces are not becoming obsolete. Instead, they are being reimagined:
- Smaller Offices: Companies might reduce office space but still maintain some physical presence for necessary in-person meetings or for those who prefer or need to work in an office environment.
- Flexible Use: Offices might transform into hubs for specific activities like team meetings, client presentations, or collaborative projects, rather than daily workspaces.
Real Estate Market: Commercial real estate markets face uncertainty. While there might be a reduction in demand for traditional office space, there could be an increase in demand for flexible, co-working spaces or spaces that can adapt to hybrid work models.
Cultural and Social Aspects: Offices serve more than just work functions; they are places for social interaction, team cohesion, and company culture. There’s a recognition that these aspects are hard to replicate fully in a remote environment, suggesting offices will retain some importance.
Future Predictions: The article predicts a hybrid model where employees might work remotely most of the time but come into the office for specific reasons or days. This could lead to a more flexible, potentially more productive workforce, but it also requires new management practices and technology solutions.
In summary, while remote work has proven viable and might continue to grow, offices are likely to evolve rather than disappear, adapting to new work patterns and possibly becoming more specialized in their function.

Total comment counts : 16
Summary
The article discusses changes in printed circuit board (PCB) design from the 1980s to the 2010s, highlighting the introduction and benefits of copper pours:
Miniaturization and Signal Integrity: By the 2010s, PCBs had become more compact with the integration of copper pours, which fill empty spaces between traces. These copper pours help improve signal integrity in high-speed electronics, essential for devices like smartphones and computers.
Regulatory Compliance: The FCC’s rules under 47 CFR Part 15 on unintentional radiators forced manufacturers to reduce RF emissions. Copper pours help in this regard by reducing electromagnetic interference, thus aiding in compliance with these regulations.
Aesthetic Trends: The use of copper pours also became fashionable within the hobbyist community, following industry trends where unusual PCB designs were often criticized.
Technical Explanation: The article explains the electromagnetic principles behind why copper pours are effective. Electromagnetic fields around charge carriers on a PCB can interact with materials like ferrite, which can absorb energy from these fields, affecting current flow. Copper pours can act similarly to inductors in managing electromagnetic interference, particularly by reducing inductance and thereby improving signal integrity at high frequencies.
Practical Application: An example is given where a PCB with a single trace and a copper plane demonstrates how AC signals behave differently from DC due to inductance, which copper pours help mitigate by providing a path for return currents that minimizes inductance effects.
Overall, the evolution in PCB design reflects not just technological advancement but also regulatory requirements and aesthetic preferences within the electronics community.
Top 1 Comment Summary
The article discusses the evolution of PCB (Printed Circuit Board) design, particularly focusing on the use of copper pours. Historically, in the 1990s, PCB designers would mask large unused areas of copper to conserve etching acid, which was expensive and had a limited lifespan based on the amount of copper it could remove. This practice also helped manage the etching process in DIY settings where conditions were not tightly controlled. DIY etching often involved basic, budget-friendly methods like using room temperature ferric chloride in simple containers, with various rudimentary techniques to apply etch resist. Masking large copper areas ensured that all copper traces were of similar width, reducing the risk of over-etching delicate parts of the PCB. Nowadays, with advancements in PCB manufacturing technology and reduced costs at professional services like PCBWay or JLCPCB, such concerns are largely obsolete due to much more controlled and efficient processes.

7. Proper decoupling capacitor practices, and why you should leave 100nF behind
Total comment counts : 19
Summary
The article delves into why the common practice of using 100nF capacitors for decoupling in electronic circuits, particularly microcontrollers, is outdated. Here’s a summary:
Decoupling Capacitors: These are used to manage the dynamic load currents in digital circuits. Every time transistors in a microcontroller switch states, they require current, leading to a need for stable power supply conditions.
Problem with 100nF Capacitors: While 100nF capacitors were widely used, they are not as effective as previously thought for modern applications due to changes in technology and understanding of circuit behavior.
Dynamic Currents (dI/dt): The article explains that the rate of change of current (dI/dt) is crucial in digital circuits, not just the clock frequency. This rate determines the frequency components that need to be managed by decoupling capacitors.
Rise and Fall Times: The speed at which signals rise or fall (rise/fall time) dictates the necessary bandwidth for decoupling, rather than the clock frequency itself. For example, a 1ns rise time requires handling frequencies up to about 350MHz.
Parasitic Effects: The physical distance between the power supply and the device, along with parasitic inductance and resistance in the circuit traces, can degrade power delivery. Inductance, in particular, causes voltage drops that manifest as noise on power rails.
Outdated Practice: The article argues that the traditional approach of using 100nF capacitors, or even adding larger capacitors in parallel, does not sufficiently address these issues due to the underestimation of parasitic effects and the actual frequency components involved in modern digital circuits.
The piece suggests a need for reevaluating decoupling strategies to better match the demands of current technology, highlighting that while 100nF capacitors have been a staple, their effectiveness is limited by today’s circuit requirements and parasitic effects.
Top 1 Comment Summary
The article discusses best practices for selecting and placing capacitors in electronic circuits:
Capacitor Value: While 1uF or 2.2uF capacitors are commonly recommended, modern designs often use higher capacitance values as engineering knowledge has advanced beyond outdated norms.
Package Size: Larger capacitors, despite offering more capacitance, can degrade high-frequency performance due to their physical size. For very high-speed designs, smaller packages like 0201 capacitors are preferred.
Distribution: Instead of using a single large capacitor, multiple smaller capacitors (e.g., 100nF) should be distributed around the PCB. This ensures effective decoupling by keeping capacitors close to the components they are intended to stabilize.
Practical Considerations: For hobbyist projects or simple microcontroller applications, exact capacitor placement and size are less critical. However, for high-speed circuits, careful consideration of capacitor placement, the number and size of vias, and minimizing loop areas are essential to maintain signal integrity.
In summary, while general guidelines exist, the specifics of capacitor use in circuit design can significantly impact performance, particularly in high-speed applications where every detail matters.
Top 2 Comment Summary
The article criticizes advice to increase capacitor size from 100nF to 1uF in USB-powered devices. Here are the main points:
Peak Currents and USB Specifications: The author argues that using larger capacitors can exceed USB power limits, potentially damaging ports or hubs due to power surge issues when devices are connected.
Capacitance Limits: Due to these limits, smaller capacitors like 100nF are preferred over larger ones like 1uF, as they add up less quickly when multiple decoupling capacitors are needed across a board.
Frequency Response: The article’s complaint about 100nF capacitors having their filtering peak at the wrong frequency is countered by the argument that this range (20MHz to 40MHz) aligns well with the operational frequencies of modern ICs, making 100nF capacitors more suitable than 1uF.
IC Compatibility: Examples like the PCM5242 IC, which has switching times suggesting the use of 100nF capacitors, support the use of smaller caps for better performance with modern electronics.
Contextual Relevance: The advice to use larger capacitors might be suitable for devices with slower ICs and dedicated power supplies, but not for USB-powered devices with modern ICs where smaller capacitors are more effective.
In summary, the author believes that for USB-powered devices using modern ICs, sticking with 100nF capacitors rather than upgrading to 1uF is more appropriate due to practical considerations in power management and IC performance.
