Ski Rental Problem The ski rental problem is a classic example problem in online algorithms. It feels like a small but interesting problem that can be explained relatively easily while some clever tricks can be applied to it. In this article, I took these lecture notes by Debmalya Panigrahi and Hangjie Ji and tried to rewrite them in a way that is easier to understand (at least for me). Formulation You are going skiing in the mountains but you are unsure about the weather reports and don't k
Even before Marvel Studios retook ownership of the Fantastic Four and got a new movie into production, there was always a bit of fondness for the old Fox movies. Not so much the 2015 one, but the mid-2000s pair directed by Tim Story and starring Ioan Gruffudd, Jessica Alba, Chris Evans, and Michael Chiklis still have their fans. Those films were general audiencesâ first introduction to the characters, and there remains a bit of attachment to those versions, particularly after Evans came back for
Jellyfish enthusiasts rejoice: Depastrum cyathiformeâa wrinkled, barrel-shaped jelly with tiny tentacles for hairâmay not actually be extinct, despite being MIA for nearly 50 years. We can thank tourist Neil Roberts, who accidentally came across the jelly while on holiday in South Uist in Scotland. This particular stalked jellyfish was much-beloved during the Victorian and Edwardian eras, appearing in exquisite detail in illustrations by famous naturalists. Historical records suggested the jell

CNET key takeways This affordable sunscreen applicator retails for $15 or less and is effective for sun protection on young children. Itâs mess-free, BPA-free and travel-friendly. Since itâs kid-friendly, older kids can apply sunscreen on their own. If you have a toddler like mine, you know what a battle it can be to get them out the door. Itâs an even bigger challenge when I apply sunscreen to my sonâs face, arms and legs. Itâs the equivalent of wrestling an alligator, and as much as Iâd lo
In partnership with developers, game marketplace GOG (Good Old Games) has launched a new website called FreedomtoBuy.games that'll let you download select "adult" games for free. GOG believes the website takes a stand "against the quiet erasure of creative works from digital shelves," a response of sorts to recent decisions from Steam and Itch to delist certain violent and sexuality-explicit games from their respective platforms. GOG is currently offering 13 games for free for the next 48 hours

YIMBYs have been winning in some of the most productive cities on Earth. Legislative victories in California and the UK have made it easier â if still not easy â to build. The logic of pro-housing reforms is both straightforward and well-supported: Fewer regulatory barriers to building mean more houses, which leads to more affordable housing and, in turn, more people able to live in dense cities that offer all the benefits of urban life. City life makes workers smarter and more productive. Urban
Some examples of people quickly accomplishing ambitious things together. San Francisco proposed a new bus lane on Van Ness in 2001. It opened in 2022, yielding a project duration of around 7,600 days. âThe project has been delayed due to an increase of wet weather since the project started,â said Paul Rose, a San Francisco Municipal Transportation Agency spokesperson. The project cost $346 million, i.e. $110,000 per meter. The Alaska Highway, mentioned above, constructed across remote tundra, c
For the past few weeks, I have been pedaling around the worldâs tiniest folding Bosch ebike as my kids (8 and 10) regard me with mingled delight and disgust. My son tried to ride away on it, with the convincing argument that this is not an adult bike, itâs a kidâs bike. I lock it up on the same rack next to my daughterâs mountain bike, and she notes that her bike is taller than mine. I ignore them all. I love this tiny bike.

This summer has seen some pretty catchy needle drops in movies, from Supermanâs Mighty Crabjoys to KPop Demon Hunters flash mob fandoms for Huntr/x and the Saja Boys. The latter Netflix release has reached not only Billboard music charts but also become the most streamed animated feature ever. With that in mind, we look back at our favorite fake bandsâ best songs of the past 30 years. While half the list includes incredible recent music from hit movies, the other half (and our number one slot)
Marvel's newest movie is here, and we have good and bad news. The good: You don't have to do any homework before seeing The Fantastic Four: First Steps, according to Marvel Studios president Kevin Feige. The bad: It's the last Marvel flick we're getting until 2026. More good: It has a super Rotten Tomatoes score. More bad: You'll miss out if you don't stick around to watch the credits. The Fantastic Four: First Steps premiered in theaters last week and kicks off Phase Six of the Marvel Cinemati
"The competition for AGIâAI that surpasses humans at all cognitive tasksâis of fundamental geopolitical importance." That's The Economist, last week. Not some breathless tech blogger or venture capitalist talking their book. The world's most prestigious economic publication. Notice the framing - it treats AGI as a foregone geopolitical contest. They're not wrong about the competition. They're just wrong about what we're competing for. I started coding again last year. First time in 13 years.

The iconic tower defense game Plants vs. Zombies is getting an HD remaster. Plants vs. Zombies: Replanted heads to the Switch and Switch 2 on October 23, as revealed during this morning's Nintendo Direct livestream. As the name suggests, it's a remake of the very first PvZ game, going all the way back to 2009.

The journalist Karen Hao â who published an absolutely fantastic book about OpenAI called âEmpire of AIâ recently â coined (as far as I know) one of the best terms for describing modern âAIâ systems: Everything Machines. âAIâ systems are not framed as specific tools that solve specific problems in specific ways but just as solution in itself: There is nothing âAIâ cannot do, if it fails we just failed it by not prompting it right or not building large enough data centers or not waiting for anot
berkozel/Getty Images Every five years or so, I make an inventory of the apps I use most frequently. It's always fascinating to see how the list has changed over time, and it usually says something about the computing landscape. When I did that exercise this year, I was astonished at the changes. Half of the apps I used five years ago are no longer on my list at all in 2025. They've been replaced, in most cases, by apps that are tightly linked with web-based services and cloud storage and can
Meta is pouring money into the physical and technical infrastructure needed to scale its AI ambitions. The company said Wednesday in its second-quarter earnings report that it plans to more than double its spend on building AI infrastructure, like data centers and servers. âWe currently expect 2025 capital expenditures, including principal payments on finance leases, to be in the range of $66-72 billionâŠup approximately $30 billion year-over-year at the midpoint,â Meta said.

Emacs: The MacOS Bug The Context I have been recently roaming. Doing some Zig, doing some Go, some Janet. Some C integration. Should have focused on my project but life threw more at me than I could handle, so I sought⊠happy distractions.
