A Hyper-V virtual machine (VM)

 A Hyper-V virtual machine (VM) is a software version of a computer that runs on a physical server. Hyper-V is a virtualization platform that allows users to run multiple VMs on the same hardware. 

Benefits of Hyper-V VMs
  • Hardware efficiency: Consolidate servers and workloads onto fewer, more powerful physical computers 
  • Flexibility: Run more than one virtual machine on the same hardware at the same time 
  • Scalability: Build an easily scalable virtual environment 
  • Business continuity: Minimize the impact of downtime 
  • Software testing: Provide a safe sandbox for developers to test software 
Hyper-V on Windows
  • Hyper-V is built into most versions of Windows 
  • It's included in Pro and Enterprise editions of Windows NT (since Windows 8) 
  • Hyper-V Server is a free stand-alone product 
Managing Hyper-V VMs
  • Hyper-V Manager is used to manage all running VMs 
  • Network Address Translation (NAT) gives a VM access to the computer's network

Partitioning a hard drive on Windows 11

 Partitioning a hard drive on Windows 11 provides several advantages, including better data organization, improved security by separating sensitive data, easier system recovery, simplified backups, and potentially enhanced performance by dedicating specific partitions to different tasks like gaming or resource-intensive applications; essentially allowing you to manage your files more efficiently and minimize the risk of data loss in case of system issues. 

Key benefits of partitioning:
  • Data organization:
    Keep personal files separate from system files, allowing for easier management and access to specific data types. 
  • Security:
    Isolate sensitive data on a separate partition, providing an extra layer of protection against malware or unauthorized access. 
  • System recovery:
    If your system partition becomes corrupted, you can easily reinstall Windows without affecting your personal data stored on a separate partition. 
  • Backup efficiency:
    Back up only the necessary partitions instead of the entire drive, making the process faster and more manageable. 
  • Performance optimization:
    Allocate specific partitions for high-performance applications, potentially improving system responsiveness. 
  • Multi-OS installation:
    Install different operating systems on separate partitions, allowing you to choose which one to boot into.

Robinhood Stock Has Soared Along With Crypto. What to Expect From Its Earnings. — Barrons.com

By Andrew Welsch

Shares of Robinhood have had a tremendous run, skyrocketing 351% over the past 12 months. When the company reports earnings Wednesday, shareholders will be looking for signs that the good times can continue to roll.

Wall Street analysts expect Robinhood to report fourth-quarter earnings per share of 41 cents on revenue of $934 million. That compares with earnings of three cents and revenue of $471 million for the fourth quarter of 2023.

Shares of Robinhood are up 43% this year compared with a 3% gain for the S&P 500. The stock was trading hands at $53.60 Tuesday afternoon.

Shareholders will be looking for updates on a variety of Robinhood's growth initiatives, including its forthcoming robo-advisor and acquisition of custodian TradePMR. The Menlo Park, Calif.-based company has been launching new products and services and dangling matching bonuses to win wallet share with clients. Robinhood had nearly 25 million customers and $195 billion in assets under custody as of Nov. 30.

Digital darling. Cryptocurrency was a catalyst for Robinhood's stock last year, and could be again in 2025, given President Donald Trump's desire to loosen crypto regulations and boost investor demand for digital assets more generally. Last month, acting SEC Chairman Mark Uyeda unveiled the formation of a task force to study cryptocurrencies and chart a "sensible regulatory path that respects the bounds of the law."

Devin Ryan, a stock analyst with Citizens JMP Securities, says there are opportunities ahead for Robinhood beyond offering investors more access to digital assets. "Ultimately, we expect Robinhood to play an important role in that connection of the legacy financial markets with blockchain, not to mention as a leader in furthering innovation with the technology, which we believe is in the firm's DNA from the start," Ryan wrote in a Jan. 24 research note.

Investors should also expect to see signs that Robinhood benefited from a surge in trading activity during the fourth quarter following the presidential election. Rival brokerage firms, such as Interactive Brokers, have already reported upticks in investor activity as part of their fourth-quarter earnings.

Eye on interest rates. In addition, analysts and investors will be on the lookout for fresh guidance on how higher-for-longer interest rates may affect Robinhood's net interest income, a key metric for banks and brokerage firms.

In a research note last month, analysts at BofA Securities said the current environment is a "goldilocks scenario" for brokerage firms given prevailing interest rates and declining cash sorting (a process by which customers move idle cash from low-paying bank sweep accounts to higher paying options such as money-market funds). The analysts said Interactive Brokers and Robinhood were top picks.

美股:债务与AI泡沫共振下的全球金融危机步入倒计时

 

当下,美股繁荣背后的结构性危机当前美股估值已进入危险区间。标普500指数的预期市盈率突破25倍,接近2000年互联网泡沫时期的水平(席勒市盈率CAPE超30倍)。科技“七巨头”(Alphabet、Meta、微软、特斯拉、亚马逊、英伟达、苹果)的资本支出在2025年预计达3310亿美元,但盈利增速从2024年的34%骤降至18%,高估值与盈利能力的背离敲响警钟。与此同时,美国联邦债务规模突破36万亿美元,企业债务创历史新高,债务驱动的虚假繁荣暗藏崩塌风险。

AI泡沫虚火旺盛AI产业被过度资本化,算力军备竞赛推高企业支出,但商业化落地不及预期。英伟达、特斯拉等龙头股市盈率远超实际业绩增速,Meta、微软等公司的天价数据中心投资(如Meta的2GW计划)更被视为豪赌。中国AI初创公司DeepSeek的破局成为导火索——其以550万美元低成本训练出比肩GPT-4的模型,颠覆了“堆算力”的估值逻辑,直接导致英伟达单日市值蒸发5900亿美元,美股AI板块一周内缩水超1万亿美元。

债务堰塞湖濒临决堤美国银行破产潮初现(2024年多家地区银行倒闭),国债拍卖遇冷,而美联储维持高利率政策(5.25%-5.5%)加剧债务偿付压力。政府每月千亿美元级利息支出迫使继续发债,形成“借新还旧”的庞氏循环。前高盛分析师莫约警告,非生产性债务(如僵尸企业借贷)占比攀升,一旦泡沫破裂将引发系统性传染,重演2008年次贷危机。

当前市场与2000年互联网泡沫时期高度相似:科技股主导指数、散户狂热、美联储政策摇摆。传奇投资人Jeremy Grantham指出,标普500等权重指数与小盘股的背离(如2024年7月标普指数下跌0.88%而等权重指数涨1.17%)已现“大轮换”信号,预示资金正从高估值科技股撤离。历史上,科技泡沫破裂后纳指最大跌幅达78%,而当前AI板块调整或刚刚开始。

美股16年长牛已至尾声,AI光环褪去与债务危机共振将引发史诗级调整。当美联储失去“救市”筹码、全球资本转向东方时,2025年或成为改写金融史的分水岭——这不是一场普通的回调,而是一次秩序重构的暴风骤雨。
