Prague food guide @EthPrague version! There will be no food provided at ETHPrague this year, so I created this handy guide to help you navigate the local food scene and find options near the venue. This will be a long post with many tips, so bookmark it and come back to it during your trip! Link to Google Maps with spots mentioned in this post below! Setting the scene: Prague is a super safe and walkable city with excellent public transportation, an amazing food scene, and a rich beer culture. Use Bolt to get from the airport to the city, it should not cost you more than $20-ish (around 600 czk). ETHPrague is hosted at Obecni Dům, which is a central location with many nearby food options. It is also close to the major attraction, the Clock Tower (Orloj), which you shouldn't miss! Where to eat and drink beer around the ETHPrague venue within a 10-minute walk: - Burger service = my fav burgers right by the venue - Pizza nuova = amazing Italian right by the venue - Pult = beer hall - Kavarna Kampus = casual beer & drink & cafe spot - Prokop Coffee & Croissants = My favorite croissants and coffee in the Old Town! - Nase Maso = casual butcher with great burgers, pastrami, steaks - Lokal Dlouhá (with many locations throughout the city) = The best Czech food and beers - Restaurace Červený Jelen = Popular steakhouse - Sia = Amazing Asian restaurant - Cukrář Skála = My favorite cake shop in Prague! You must try their ice cream too! - Kantýna = Traditional Czech cuisine, expect meaty meals and great beer - Zem Prague = Upscale Czech cuisine, perfect for business dinners or lunches. - Vinograf = excellent food, on the higher-end side There’s also a mall with fast-food restaurants very close to the venue, offering plenty of food options—consider this as a backup! Extra tips! - Dlouha street = full of commercial clubs, popular bars, and a great younger party-and-going-out vibe. Clubs and Bars located on this street (about a 10-minute walk from Obecni dum): Roxy, James Dean, Steampunk Prague = usually the “afterparty” spot, Kenton’s New York Bar, FRAME = excellent gin & tonic bar! - More underground clubs = Cross club, Bukanyr, Fuchs2, Bike jesus - Matuška Brewery (two locations) = Their beer recently won two medals in the World Beer Competition (out of 1,600 beers!). - Prague has tons of laptop-friendly cafes, such as Space Cafe Karlín, Kolektor, Miners (in Letná), Cafe Neustadt, Tvaroh... - Riegrovy Sady: Park with an amazing sunset view and a beer garden. Tourists must see spots not to miss: - Orloj watch tower (about 10min walk from the ETH Prague venue) - Charles Bridge - Prague Castle (accessible from the Restaurant Lví Dvůr area—otherwise, you have to walk up the hill!) - Walk to see the major Prague “must-see” spots: Start at the castle (begin by the restaurant Lví Dvůr), walk through the castle area, visit “Zlatá ulička” (it’s paid, but worth a visit!), then continue down to the Lennon Wall and stroll around the beautiful area locals call “Czech Venice” (it’s tiny). Cross Charles Bridge to the Orloj. This should take about 20–40 minutes, depending on the time of day and how crowded it is. Random facts about Prague + good to know: - Prague has tons of Vietnamese spots, and most of the corner stores (večerka) are run by Vietnamese people. - The best pho is at Pho100! - Beer is sometimes cheaper than water. - Do NOT use public transportation without a ticket. Ticket inspectors are very strict and can be confrontational. Just buy a ticket or pay the fine (about 50 euros)—don’t argue with them for your own peace of mind. - Prague used to have the most Michelin-starred restaurants in the EU—it’s a foodie heaven! - You can find tons of great cafes and restaurants in Prague! Use the app “Coffee Trip” and filter by what you’re looking for. Anything else that I missed in this guide that you would find helpful? Comment, and I will try to reply!

@Hesamation Kudos for pointing out the hypocrisy

YC’s call for startups: “Make us electronics for space” What they end up funding: Brainrot IDE

@Virendra0698 No one cares 😂

@Maaztwts Aggregators don't cover toll fares and parking charges but the blame goes to the cab drivers.

Rapido Scam at BLR Airport? Here’s What Happened at 1AM Okay so story time. Last week I was in Bangalore for YC SUS and the Codex Hackathon, and I booked a Rapido cab from BLR Airport to my hotel for ₹723. Midway through the ride, the driver suddenly said I need to pay ₹410 extra for parking and tolls. I refused, but he started getting aggressive, so at around 1 AM, I called my hackathon teammate and asked if this was even fair. He talked to the driver, but the driver kept saying “serr serr it is fair sir I don’t lie serr” and just wouldn’t listen. And also he stopped the cab in the middle of the route. I was afraid at that time, tbh, cause the location where he stopped the cab was also shady. Then I asked him to show me the message where he got the parking charge from. Obviously he had nothing, then told me to wait and literally generated one on the spot. I saw the payment time was just a second ago and lmao I took his phone, clicked pictures of the number the message came from, and said yeah let’s go I’ll pay. On top of that, Rapido’s support is just terrible. There is no proper call option in the app. After coming back to Delhi, I used their chat support and had to explain the same issue four different times to four different agents. Three times the chat was just closed with “this is between you and the driver(they literally dropped the cab driver number to resolve the issue by my own), resolve it yourself.” On the fourth attempt, only after I mentioned legal action and posting on social media, they finally processed the refund. That honestly shows how pathetic and unreliable their support system is. This post is only meant to warn people who are planning to take a Rapido ride from BLR Airport, so please be aware of this kind of scam. @rapidobikeapp @RapidoCares

@ashwinexe @OpenAI @AniketRaj314 @gabrielchua @yashrajnayak @OpenAIDevs @reach_vb RIP Sora 💀

We won the 2nd place @OpenAI Codex Hackathon 🏆 Yes, we (@AniketRaj314 and I) made both the project and the video live in ~6 hours. Here’s the demo video. Shout out @gabrielchua @yashrajnayak @OpenAIDevs and the whole team for organising this. #CodexBLR

“Funny how when it’s Carlsen, the narrative is ‘global superstar’. When it’s Gukesh vs Sindarov, it’s ‘two players nobody outside chess or India can name’. At some point we have to admit it’s not about strength, it’s about which countries get to define ‘fame’.”

@KamStaszewski @nengjiali The thread may be llm generated. Check the github and the repos the work and the learning journey is 100% real. As someone who took a similar journey 5 months ago, I can attest this is a feat. The work's extremely time consuming and frustrating. 👏 @nengjiali .

@nengjiali Thread is so LLM generated, sentences explaining what you did are robotic. Wish they were more human. Have you responded to previous allegations? I'm having hard time believing integrity of your projects. Great presentation though x.com/Rafael_L_Sprin…

I spent 4 brutal months building a full Stereo Visual SLAM system from scratch in C++17 + CUDA. NO pre-made libraries. NO black-box magic. I just wanted to understand the underlying mechanics behind SLAM. Here’s the intuitive breakdown (the full SLAM pipeline, the math that almost broke me, and the real KITTI footage)👇 cc @aelluswamy your work in this space is a massive inspiration for tackling this from absolute scratch

@enjojoyy @ETHGlobal I mean, I kinda disagree — there wasn’t any clear policy about my stake situation either. maybe it worked, cuz i didn't go in demanding a refund. idk 🤷 But yeah, if they’re still refusing in your case, your best bet is to scalp, tbh.

@laciferin @ETHGlobal Stake is different than conference ticket. Obviously I mailed them.

.@ETHGlobal didn’t return me money for a conference ticket that I can’t attend because I got a US visa rejected (that I also paid a lot to apply for) such an insane policy of “final sales” EU could never, but Canada/US can As a hackathon finalist, I don’t have a desire to participate in their hackathons and events anymore
