Updated for Rent Day 12/1. Bilt Rewards recently announced “Bilt 2.0” which promises three new credit cards with rewards on both mortgage payments and rent. Applications are not open yet; More details supposedly coming January 2026. If you have the existing card issued by Wells Fargo, it is scheduled to work as usual until February 6th, 2026.

December 1st, Bilt is offering a transfer bonus to British Airways* Avios of between 50% and 100%. (* or Aer Lingus and Iberia Avios.) Avios can be pretty useful in many cases, and this transfer bonus is a potential way of getting excellent value out of your Bilt points, if you have a redemption in mind.

If you haven’t, you should also link your Rakuten account to Bilt for a small but pretty easy bonus. Look for the option in the app.

Rent Day also means 2X double points where you can get 6X on dining, 4X on travel, and 2X on other purchases (except rent). There is a cap of 1,000 bonus points. Remember that you must use your card to make 5 purchases (of any amount) each statement period to earn points.

Existing Bilt members can still earn lots of Bilt points just for paying monthly rent to any landlord with no transaction fees, which is their most important feature.

Full review on the old card:

The updated Bilt Mastercard is a unique credit card that earns rewards on rent payments to any landlord. Bilt is a rent payment platform and they will send your landlord a check or ACH bank transfer so that your landlord will not have to do anything. The credit card itself is issued by Wells Fargo. Bilt has bonus categories and a variety of points redemption options like many other rewards credit cards. Here are the highlights:

• Up to 1X points spent on rent payments without the transaction fee, up to 100,000 points each calendar year.
• 3X points on dining.
• 2X points on travel including hotels, rental cars, and cruises when booked directly with airlines, hotels, and car rental agencies.
• 1X points on other purchases.
• Earn points when you make 5 transactions that post each statement period.
• When renting at a Bilt Alliance property, you can choose to have your rent payments automatically reported by Bilt to the three major credit bureaus each month; Experian(TM), TransUnion(TM), and Equifax(TM).
• No annual fee.
• World Elite Mastercard perks like cell phone insurance and purchase protection.

That means your rent can be up to $100,000 per year ($8,333 per month) and you would still be able to take full advantage of the 1X points per dollar spent on rent payments. They do require you to make at least 5 transactions per month (rent can be one), otherwise too many people might just put their rent on the card and not use the card otherwise.

Bilt has partnered with the owners of over 2,000,000 apartment units to create the Bilt Rewards Alliance. The easiest way is find out if you live in a qualifying property is to simply type in your address into the Bilt app.

Bilt also offers Double Points on “Rent Day”, aka the 1st of every month. This means that on the 1st day of every month, you can get 6X on dining, 4X on travel, and 2X on other purchases(except rent). They also offer other promos on this day.

Bilt Rewards Points redemption options

Travel partners. Bilt Rewards points transfer on a 1:1 basis to the following hotel and airline partners. You can also get 100 bonus points for every loyalty program you link to Bilt.

• Alaska Airlines Atmos (Hawaiian)
• Air Canada Aeroplan
• United Airlines
• FlyingBlue (Air France/KLM)
• Miles & Smiles (Turkish Airlines)
• Emirates Skywards
• Cathay Pacific Asia Miles
• British Airways Executive Club
• Virgin Atlantic Flying Club
• Aer Lingus Aer Club
• Turkish Miles & Smiles
• Iberia Plus
• TAP Air Portugal
• World of Hyatt
• IHG One
• Accor ALL

Hyatt hotel points, Alaska, and United are likely the most useful points for the average US traveler. I am conservative when valuing points and miles due to their redemption hassles and steady threat of devaluation, so I would place the value here a 1 cent a point even though I definitely plan to exceed that. You may wish to use a different value.

Home Downpayment? Bilt says that your points can be redeemed at 1.5 cents per point when used towards a home downpayment. This seems like it might be rather complicated to actually redeem, so I would keep it mind but wouldn’t count on it. If you racked up 100,000 points over time, it would be nice to have $1,500 via this method.

Shop with Points at Amazon. You can link your Bilt Rewards points to Amazon and pay for your purchases at rate of 0.70 cents per point.

Rent. Bilt will let you convert points towards your next rent payment at 0.55 cents per point. This is not a good redemption rate when compared to the miles/Hyatt option. It’s too bad there is no easy, decent cash-out option.

Statement credit. Bilt will also let you convert points towards a statement credit on your credit card statement at 0.55 cents per point.

Other options include fitness classes or physical items like “limited-edition” home decor or art in the “Bilt Collection” catalog. Personally, I like being able to add to my Hyatt and Canada Aeroplan stash.

Possibly help your credit score? When renting at a Bilt Alliance property, your on-time payment activity can be automatically reported to the three major credit bureaus. In addition, with the optional “BiltProtect” feature, your rent payments will be immediately withdrawn from a linked bank account so your credit limit is not decreased (and ideally your rent won’t contribute to your credit card debt).

How do I pay my landlord or property manager? They don’t take credit cards due to the transaction fees. Bilt will provide you with a bank ACH routing number and account number that you can use to perform an ACH transfer, or they will simply send a paper check on your behalf. In March 2025, Bilt added a pre-authorization step that you have to do first in the Bilt app. After that they will provide you new routing and account numbers. You don’t actually pay with the credit card, nor do you or your landlord have to pay any credit card transaction fees.

1. Pre-authorize your payment in the Bilt app (before you pay rent)
Each month, pre-authorize your rent payment from the Bilt app, up to five (5) days before paying rent.
Select your rent amount and payment method.
Use your Bilt Mastercard® for your usual rewards and waived fees, or
Use any other credit/debit card to earn both Bilt Points AND your card’s rewards.
First time only: You’ll receive your BillPay by Bilt routing and account numbers. Add these to your property’s payment portal, replacing your old Rent Rewards account details.
Optional: After setting up BillPay, you can enable auto-authorization under ‘Rent Payment Options’ by selecting the day of the month and payment amount you want automatically authorized each month.

Free cell phone protection. Pay your monthly cell phone bill with your Bilt Mastercard and get up to $800 of protection (subject to $25 deductible) against covered damage or theft. For complete coverage details, visit wellsfargo.com/biltbenefits. To file a claim, call 1-800-316-8051 or visit mycardbenefits.assurant.com.

Bottom line. The Bilt Mastercard offers a unique rewards structure targeted specifically at all renters with any landlord. At $2,000 a month in rent, the 1X rewards would add up to 24,000 points per year in rewards = 24,000 Alaska Atmos (Hawaiian) or United miles or 24,000 Hyatt points with no additional transaction fees and no credit card annual fee. You may even do better if you wait for a “Rent Day” promo on the first of the month. Something to consider if you already have to pay rent anyway.

After a successful November 27th launch to the International Space Station, Russia discovered an accident had occurred on their launch site's mobile maintenance cabin — when a drone spotted it lying upside down in a flame trench. "The main issue with the structure collapse is that it puts Site 31/6 — the only Russian launch site capable of launching crew and cargo to the International Space Station (ISS) — out of service until the structure is fixed," reports the space-news site NASA Spaceflight There are other Soyuz 2 rocket launch pads, but they are either located at an unsuitable latitude, like Plesetsk, or not certified for crewed flights, like Vostochny, or decommissioned and transferred to a museum, like Gagarin's Start at Baikonur. As a result, Russia is temporarily unable to launch Soyuz crewed spacecraft and Progress cargo ships to the ISS, whose nearest launch (Progress MS-33) was scheduled for December 21.... When the rocket launched, a pressure difference was created between the space under the rocket, where gases from running engines are discharged, and the nook where the [144-ton] maintenance cabin was located. The resulting pressure difference pulled the service cabin out of the nook and threw it into the flame trench, where it fell upside down from a height of 20 m. Photos of the accident showed significant damage to the maintenance cabin, which, according to experts, is too extensive to allow for repairs. The only way to resume launches from Site 31/6 is to install a spare maintenance cabin or construct a new one. Despite the fact that the fallen structure was manufactured in the 1960s, two similar service cabins were manufactured recently at the Tyazhmash heavy-engineering plant in Syzran for other Soyuz launch complexes at the Guiana Space Center and Vostochny Cosmodrome. The production of each cabin took around two years to complete, however, it was not for an emergency situation. "Various experts gave different possible estimates of the recovery time of the Site 31 launch complex: from several months to three years."

Some AI experts were reportedly shocked ChatGPT wasn't fully tested for sycophancy by last spring. "OpenAI did not see the scale at which disturbing conversations were happening," writes the New York Times — sharing what they learned after interviewing more than 40 current and former OpenAI employees, including safety engineers, executives, and researchers. The team responsible for ChatGPT's tone had raised concerns about last spring's model (which the Times describes as "too eager to keep the conversation going and to validate the user with over-the-top language.") But they were overruled when A/B testing showed users kept coming back: Now, a company built around the concept of safe, beneficial AI faces five wrongful death lawsuits... OpenAI is now seeking the optimal setting that will attract more users without sending them spiraling. Throughout this spring and summer, ChatGPT acted as a yes-man echo chamber for some people. They came back daily, for many hours a day, with devastating consequences.... The Times has uncovered nearly 50 cases of people having mental health crises during conversations with ChatGPT. Nine were hospitalised; three died... One conclusion that OpenAI came to, as Altman put it on X, was that "for a very small percentage of users in mentally fragile states there can be serious problems." But mental health professionals interviewed by the Times say OpenAI may be understating the risk. Some of the people most vulnerable to the chatbot's unceasing validation, they say, were those prone to delusional thinking, which studies have suggested could include 5% to 15% of the population... In August, OpenAI released a new default model, called GPT-5, that was less validating and pushed back against delusional thinking. Another update in October, the company said, helped the model better identify users in distress and de-escalate the conversations. Experts agree that the new model, GPT-5, is safer.... Teams from across OpenAI worked on other new safety features: The chatbot now encourages users to take breaks during a long session. The company is also now searching for discussions of suicide and self-harm, and parents can get alerts if their children indicate plans to harm themselves. The company says age verification is coming in December, with plans to provide a more restrictive model to teenagers. After the release of GPT-5 in August, [OpenAI safety systems chief Johannes] Heidecke's team analysed a statistical sample of conversations and found that 0.07% of users, which would be equivalent to 560,000 people, showed possible signs of psychosis or mania, and 0.15% showed "potentially heightened levels of emotional attachment to ChatGPT," according to a company blog post. But some users were unhappy with this new, safer model. They said it was colder, and they felt as if they had lost a friend. By mid-October, Altman was ready to accommodate them. In a social media post, he said that the company had been able to "mitigate the serious mental health issues." That meant ChatGPT could be a friend again. Customers can now choose its personality, including "candid," "quirky," or "friendly." Adult users will soon be able to have erotic conversations, lifting the Replika-era ban on adult content. (How erotica might affect users' well-being, the company said, is a question that will be posed to a newly formed council of outside experts on mental health and human-computer interaction.) OpenAI is letting users take control of the dial and hopes that will keep them coming back. That metric still matters, maybe more than ever. In October, [30-year-old "Head of ChatGPT" Nick] Turley, who runs ChatGPT, made an urgent announcement to all employees. He declared a "Code Orange." OpenAI was facing "the greatest competitive pressure we've ever seen," he wrote, according to four employees with access to OpenAI's Slack. The new, safer version of the chatbot wasn't connecting with users, he said. The message linked to a memo with goals. One of them was to increase daily active users by 5% by the end of the year.

It's "a complex mix of internet access and physical execution," says the chief informance security officer at Cequence Security. Long-time Slashdot reader schwit1 summarizes this article from The Wall Street Journal: By breaking into carriers' online systems, cyber-powered criminals are making off with truckloads of electronics, beverages and other goods In the most recent tactics identified by cybersecurity firm Proofpoint, hackers posed as freight middlemen, posting fake loads to the boards. They slipped links with malicious software into email exchanges with bidders such as trucking companies. By clicking on the links, trucking companies unwittingly downloaded remote-access software that lets the hackers take control of their online systems. Once inside, the hackers used the truckers' accounts to bid on real shipments, such as electronics and energy drinks, said Selena Larson, a threat researcher at Proofpoint. "They know the business," she said. "It's a very convincing full-scale identity takeover." "The goods are likely sold to retailers or to consumers in online marketplaces," the article explains. (Though according to Proofpoint "In some cases, products are shipped overseas and sold in local markets, where proceeds are used to fund paramilitaries and global terrorists.") "The average value of cargo thefts is increasing as organized crime groups become more discerning, preferring high-value targets such as enterprise servers and cryptocurrency mining hardware, according to risk-assessment firm Verisk CargoNet."

An anonymous reader shared this report from The Conversation: To make interplanetary travel faster, safer, and more efficient, scientists need breakthroughs in propulsion technology. Artificial intelligence is one type of technology that has begun to provide some of these necessary breakthroughs. We're a team of engineers and graduate students who are studying how AI in general, and a subset of AI called machine learning in particular, can transform spacecraft propulsion. From optimizing nuclear thermal engines to managing complex plasma confinement in fusion systems, AI is reshaping propulsion design and operations. It is quickly becoming an indispensable partner in humankind's journey to the stars... Early nuclear thermal propulsion designs from the 1960s, such as those in NASA's NERVA program, used solid uranium fuel molded into prism-shaped blocks. Since then, engineers have explored alternative configurations — from beds of ceramic pebbles to grooved rings with intricate channels... [T]he more efficiently a reactor can transfer heat from the fuel to the hydrogen, the more thrust it generates. This area is where reinforcement learning has proved to be essential. Optimizing the geometry and heat flow between fuel and propellant is a complex problem, involving countless variables — from the material properties to the amount of hydrogen that flows across the reactor at any given moment. Reinforcement learning can analyze these design variations and identify configurations that maximize heat transfer.
