Alan Turing Institute Plans Revamp in Face of Criticism and Technological Change

Slashdot.org - Tue, 04/01/2025 - 05:35
Britain's flagship AI agency will slash the number of projects it backs and prioritize work on defense, environment and health as it seeks to respond to technological advances and criticism of its record. From a report: The Alan Turing Institute -- named after the pioneering British computer scientist -- will shut or offload almost a quarter of its 101 current initiatives and is considering job cuts as part of a change programme that led scores of staff to write a letter expressing their loss of confidence in the leadership in December. Jean Innes, appointed chief executive in July 2023, argued that huge advances in AI meant the Turing needed to modernise after being founded as a national data science institute by David Cameron's government a decade ago this month. "The Turing has chalked up some really great achievements," Innes said in an interview. "[But we need] a big strategic shift to a much more focused agenda on a small number of problems that have an impact in the real world." A review last year by UK Research and Innovation, the government funding body, found "a clear need for the governance and leadership structure of the Institute to evolve." It called for a move away from the dominance of universities to a structure more representative of AI in UK.

MMB Portfolio Asset Allocation & Performance – 2025 Q1 Update

MyMoneyBlog.com - Tue, 04/01/2025 - 02:53

I try to limit checking my portfolio to once a quarter, and this is my 2025 Q1 update that includes our combined 401k/403b/IRAs and taxable brokerage accounts but excluding our house and side portfolio of self-directed investments. Following the concept of skin in the game, the following is not a recommendation, but a sharing of our actual, imperfect DIY portfolio.

“Never ask anyone for their opinion, forecast, or recommendation. Just ask them what they have in their portfolio.” – Nassim Taleb

How I Track My Portfolio
Here’s how I track my portfolio across multiple brokers and account types:

  • The Empower Personal Dashboard real-time portfolio tracking tools (free) automatically logs into my different accounts, adds up my various balances, tracks my performance, and calculates my overall asset allocation daily. Formerly known as Personal Capital.
  • Once a quarter, I also update my manual Google Spreadsheet (free to copy, instructions) because it helps me calculate how much I need in each asset class to rebalance back towards my target asset allocation. I also create a new tab each quarter, so I have a personal archive of my net worth dating back many years.

2025 Q1 Asset Allocation and YTD Performance
Here are updated performance and asset allocation charts, per the “Holdings” and “Allocation” tabs of my Empower Personal Dashboard.

The major components of my portfolio are broad index ETFs. I do mix it up a bit around the edges, but not very much. Here is a breakdown of my target asset allocation along with my primary ETF holding for each asset class.

  • 35% US Total Market (VTI)
  • 5% US Small-Cap Value (VBR/AVUV)
  • 20% International Total Market (VXUS)
  • 5% International Small-Cap Value (AVDV)
  • 5% US Real Estate (REIT) (VNQ)
  • 20% US “Regular” Treasury Bonds or FDIC-insured deposits
  • 10% US Treasury Inflation-Protected Bonds

Big picture, it is 70% businesses and 30% very safe bonds/cash:

By paying minimal costs including management fees, transaction spreads, and tax drag, I am trying to essentially guarantee myself above-average net performance over time.

I do not spend a lot of time backtesting various model portfolios, as I don’t think picking through the details of the recent past will necessarily create superior future returns. You’ll usually find that whatever model portfolio is popular at the moment just happens to hold the asset class that has been the hottest recently as well.

The portfolio that you can hold onto through the tough times is the best one for you. Every asset class will eventually have a low period, and you must have strong faith during these periods to earn those historically high returns. You have to keep owning and buying more stocks through the stock market crashes. You have to maintain and even buy more rental properties during a housing crunch, etc. A good sign is that if prices drop, you’ll want to buy more of that asset instead of less. I don’t have strong faith in the long-term results of commodities, gold, or bitcoin – so I don’t own them.

Performance details. According to Empower, the S&P 500 went down about 5% the first quarter of 2025, while foreign stocks went up around 7%. I don’t remember that happening for a while, and apparently it hasn’t happened since 2009 (see below;source). Overall, my portfolio was flat.

Over the last quarter, here’s a Growth of $10,000 chart courtesy of Testfolio for some of the major ETFs that shows the difference in performance in the broad indexes:

I always like to remember the big picture. Here’s an updated Morningstar Growth of $10,000 Chart for the Vanguard LifeStrategy Growth Fund (VASGX) which holds a static 80% stocks and 20% bonds and most closely mimics my portfolio since 2005, which is when I started investing more seriously and started this blog.

I’ll share about more about the income aspect in a separate post.

Anthropic Will Begin Sweeping Offices For Hidden Devices

Slashdot.org - Tue, 04/01/2025 - 00:30
Anthropic said it will start sweeping physical offices for hidden devices as part of a ramped-up security effort as the AI race intensifies. From a report: The company, backed by Amazon and Google, published safety and security updates in a blog post on Monday, and said it also plans to establish an executive risk council and build an in-house security team. Anthropic closed its latest funding round earlier this month at a $61.5 billion valuation, which makes it one of the highest-valued AI startups. In addition to high-growth startups, tech giants including Google, Amazon and Microsoft are racing to announce new products and features. Competition is also coming from China, a risk that became more evident earlier this year when DeepSeek's AI model went viral in the U.S. Anthropic said in the post that it will introduce "physical" safety processes, such as technical surveillance countermeasures -- or the process of finding and identifying surveillance devices that are used to spy on organizations. The sweeps will be conducted "using advanced detection equipment and techniques" and will look for "intruders."

First Flight of Isar Aerospace's Spectrum Rocket Lasted Just 40 Seconds

Slashdot.org - Mon, 03/31/2025 - 22:30
An anonymous reader quotes a report from Ars Technica: The first flight of Isar Aerospace's Spectrum rocket didn't last long on Sunday. The booster's nine engines switched off as the rocket cartwheeled upside-down and fell a short distance from its Arctic launch pad in Norway, punctuating the abbreviated test flight with a spectacular fiery crash into the sea. If officials at Isar Aerospace were able to pick the outcome of their first test flight, it wouldn't be this. However, the result has precedent. The first launch of SpaceX's Falcon 1 rocket in 2006 ended in similar fashion. "Today, we know twice as much about our launch system as yesterday before launch," Daniel Metzler, Isar's co-founder and CEO, wrote on X early Monday. "Can't beat flight testing. Ploughing through lots of data now." Isar Aerospace, based in Germany, is the first in a crop of new European rocket companies to attempt an orbital launch. If all went according to plan, Isar's Spectrum rocket would have arced to the north from Andoya Spaceport in Norway and reached a polar orbit. But officials knew there was only a low chance of reaching orbit on the first flight. For this reason, Isar did not fly any customer payloads on the Spectrum rocket, designed to deliver up to 2,200 pounds (1,000 kilograms) of payload mass to low-Earth orbit. [...] Isar declared the launch a success in its public statements, but was it? [...] Metzler, Isar's chief executive, was asked last year what he would consider a successful inaugural flight of Spectrum. "For me, the first flight will be a success if we don't blow up the launch site," he said at the Handelsblatt innovation conference. "That would probably be the thing that would set us back the most in terms of technology and time." This tempering of expectations sounds remarkably similar to statements made by Elon Musk about SpaceX's first flight of the Starship rocket in 2023. By this measure, Isar officials can be content with Sunday's result. The company is modeling its test strategy on SpaceX's iterative development cycle, where engineers test early, make fixes, and fly again. This is in stark contrast to the way Europe has traditionally developed rockets. The alternative to Isar's approach could be to "spend 15 years researching, doing simulations, and then getting it right the first time," Metzler said. With the first launch of Spectrum, Isar has tested the rocket. Now, it's time to make fixes and fly again. That, Isar's leaders argue, will be the real measure of success. "We're super happy," Metzler said in a press call after Sunday's flight. "It's a time for people to be proud of, and for Europe, frankly, also to be proud of." You can watch a replay of the live launch webcast on YouTube.

'There is No Vibe Engineering'

Slashdot.org - Mon, 03/31/2025 - 20:30
Software engineer Sergey Tselovalnikov weighs in on the new hype: The term caught on and Twitter quickly flooded with posts about how AI has radically transformed coding and will soon replace all software engineers. While AI undeniably impacts the way we write code, it hasn't fundamentally changed our role as engineers. Allow me to explain. [...] Vibe coding is interacting with the codebase via prompts. As the implementation is hidden from the "vibe coder", all the engineering concerns will inevitably get ignored. Many of the concerns are hard to express in a prompt, and many of them are hard to verify by only inspecting the final artifact. Historically, all engineering practices have tried to shift all those concerns left -- to the earlier stages of development when they're cheap to address. Yet with vibe coding, they're shifted very far to the right -- when addressing them is expensive. The question of whether an AI system can perform the complete engineering cycle and build and evolve software the same way a human can remains open. However, there are no signs of it being able to do so at this point, and if it one day happens, it won't have anything to do with vibe coding -- at least the way it's defined today. [...] It is possible that there'll be a future where software is built from vibe-coded blocks, but the work of designing software able to evolve and scale doesn't go away. That's not vibe engineering -- that's just engineering, even if the coding part of it will look a bit different.
