The user raises concerns about the usability of popular e-commerce platforms like Pinduoduo, Taobao, and Jingdong on desktop browsers. The main argument is that these platforms may be intentionally optimizing their mobile apps at the expense of the desktop experience, potentially to gather more user data and control the shopping experience. One user poignantly stated, “They just don't want you to compare prices easily and want to trap you in a phone.”

Many users echoed this sentiment, expressing frustration with the clunky and inefficient desktop versions of these platforms. Complaints ranged from search difficulties and anti-scraping measures to complicated payment processes and UI inconsistencies. Some users believe that the deliberate degradation of the PC experience is a tactic to push users towards mobile apps, which offer more opportunities for tracking and data collection. Other users shared their experiences:

• shakaraka: Expressed a desire to use PC for shopping but finds the experience too difficult.
• katwalk: Maintains that Taobao, Jingdong, and Xianyu have usable web versions, with Taobao even releasing an optimized version this year.
• Dispatcher: Strongly criticizes the PC experience on these platforms, citing numerous issues and accusing them of intentionally undermining it to gather more user data through apps.
• dobelee: Echoes the frustration with the PC experience, lamenting the difficulty of comparing products on mobile apps.

Despite the criticisms, some users still prefer using computers for online shopping due to the larger screen size and the ability to compare multiple products simultaneously. This highlights a potential gap in the market for e-commerce platforms that prioritize a user-friendly desktop experience.

The conversation underscores the ongoing debate about user experience in the age of mobile-first design. While mobile apps offer convenience and accessibility, the discussion raises important questions about whether the desktop experience is being neglected and whether this is a deliberate strategy to control user behavior and data.

3. The Cost of App Development: Is It Worth It?

A budding Android developer shared their frustration about the costs associated with publishing an app, particularly the need for electronic copyright certificates in China and the developer registration fee for Google Play.

7. Device Ban on Xiaohongshu: A User's Experience with Platform Risk Control

A user shares their experience with risk control measures on Xiaohongshu (a popular Chinese social media and e-commerce platform) and Coolapk (a Chinese Android app store). The user’s Xiaohongshu account was flagged for violating community guidelines, specifically for using automated programs or engaging in repetitive behavior. The user suspects that their device has been blacklisted by the platform due to having a rooted Android phone with the XP framework and a modified Xiaohongshu app installed. This led to a series of events, including difficulties with the appeal process and the account being flagged again after a temporary unblocking. The key concern is the potential for device-level bans and the implications for users who sell or repurpose their devices. The user's detailed account raises important questions about platform risk control mechanisms and their impact on user privacy and device usability. Key points from the user's experience:

• Account flagged for using automated programs.
• Suspects device ban due to rooted phone and modified app.
• Difficulties with the appeal process.
• Account re-flagged after temporary unblocking.
• Concerns about device blacklisting and implications for resale.

Other users shared their insights and experiences:

• docx: Clarifies that the issue is about the platform risk control after one account is flagged, other accounts logged on the same device will also be flagged, which is pretty normal, and some platforms might even flag the IP address.
• DandelionFlowers: Mentions using Xiaohongshu as a search engine for daily consumption, finding roommates, etc.
• longzhou6431: Expresses a negative view of Xiaohongshu due to the user having seen many irrational posts.

The user's experience highlights the importance of understanding platform guidelines and the risks associated with using modified apps or rooted devices. The conversation also touches upon the broader debate about platform power and the need for transparency in risk control mechanisms.

8. 3D Acceleration in Windows Virtual Machines: A Lingering Challenge?

This technical discussion focuses on the challenges of achieving hardware-accelerated 3D graphics in Windows virtual machines (VMs) using KVM-based virtualization platforms like Proxmox VE (PVE), Unraid, oVirt, and OpenStack. The user explains that Windows desktop effects and certain software rely on 3D acceleration and OpenGL, and the lack of it can lead to high CPU usage. While solutions like VirtualBox and VMware offer seamless 3D acceleration through guest additions, KVM-based solutions lack a similarly robust and stable option. The user specifically mentions virgl, but notes its instability, poor performance, and limitations on VM sleep/hibernate functionality. This query is highly relevant for users who need to run graphically demanding applications or simply want a smoother desktop experience within a KVM-based VM. Key points raised in the discussion:

• Difficulty in achieving hardware-accelerated 3D graphics in KVM-based Windows VMs.
• Limitations of existing solutions like virgl.
• Need for a stable and performant alternative to VirtualBox/VMware guest additions.
• Inquiry about 3D acceleration solutions used by cloud server providers.

Key insights shared by other users:

• liyafe1997: Confirms the lack of a good solution for 3D acceleration in KVM VMs.
• einsdisp: Inquires about 3D acceleration solutions used by cloud server providers for Windows desktop VMs, questioning whether they use vGPUs or software virtualization.
• ryd994: Suggests using RemoteFX over RDP and clarifies that cloud hosts typically don't provide GPUs for desktop use, especially since virtual displays are usually only used for rescue operations. Further points out that even regular servers mostly use a basic graphics card. If a server has proper out-of-band management, it might not even need a graphics card at all and do headless installations with remote serial console for rescue operations.
• ntedshen: Claims that modern CPUs can handle Windows effects without significant CPU load.

This discussion highlights a persistent gap in the KVM virtualization ecosystem, particularly for users who require a seamless and efficient 3D graphics experience in Windows VMs. The lack of a readily available solution forces users to consider alternative virtualization platforms or resort to resource-intensive software rendering.

9. High Risk, Low Reward: Rethinking Risk in Investment

This post delves into the complexities of risk and reward in investing, challenging the conventional wisdom that higher risk always equates to higher returns. The author uses two simple math problems to illustrate how high-volatility investments can sometimes yield disappointing results, even when they ultimately turn a profit. The first problem demonstrates how a 55% gain followed by a 34% loss results in only a 2% profit. The second problem compares two investment scenarios, one with a 100% gain followed by a 30% loss, and another with two consecutive 20% gains, demonstrating that the latter yields a higher return. These examples highlight the impact of compounding and the importance of managing downside risk. The central argument is that not all risks are created equal, and some risks offer a poor risk-reward ratio. The author emphasizes the need to differentiate between “good” risks, which have a worthwhile potential payoff, and “bad” risks, which offer limited upside even when successful. The author aims to identify good risks and avoid bad risks, emphasizing that some risks are not worth taking even if they appear to be profitable on the surface.

Key insights from the discussion:

• zisen: Acknowledges the need for individual judgment in identifying risks and opportunities, expressing admiration for those who “buy the dip,” while being aware that it also carries the risk of ruin.
• Sawyerhou & daweii: Introduce the concepts of the Efficient Frontier and the Sharpe Ratio, which are used to assess risk-adjusted returns. daweii suggests considering investing in SPY or QQQ.
• cmdOptionKana: Highlights Sharpe Ratio for long-term investment but asks about short-term strategies, and brings up the problems of the “zero-sum game, mean reversion”.
• apollo007: States that Value investing has low risk and high reward. Going for already over-heated stocks is the opposite.
• cmdOptionKana: Discusses difficulties in calculating probabilities in practice and the potential for black swan events, suggesting that the risk of ruin needs to be considered when considering probabilities.
• ash1n2: Suggests this post is about the payoff odds but the examples are not entirely related, with examples showing volatility rather than payoff odds.

The conversation underscores the nuances of risk assessment in investing and the importance of considering factors beyond potential returns. The discussion touches upon key concepts like risk-adjusted returns, portfolio diversification, and the psychological challenges of value investing. It is a valuable resource for investors seeking to refine their risk management strategies.
