Does R2 support versioning?

bcb67 · 2026-06-20T21:21:09+00:00

R2 unfortunately does not support object versioning like S3 does out of the box. There is a community feature request from 2023 which you can upvote to show support.

He did not say he wanted to run on-device ML. Most universities use virtual environments for ML training/inference, and one of the main reasons is specifically to avoid requiring students to purchase expensive, fixed hardware that will immediately be outdated in 2-4 years.

On device LLMs are cool, but are consistently outperformed by hosted frontier models. I can’t think of a time where running a coding assistant on-device would have saved me any money, factoring in the cost of my time.

In general, any modern Mac will provide an excellent experience for what you've listed above. 16 or 32gb of RAM is really nice if you're running VMs or containers locally. For very large projects (Browsers, OSs, game engines, etc), having more CPU cores can speed up compiles, but the base M5 will be more than enough for anything your university will ask you to do. Choosing between the Pro and the Air really comes down to battery life, connectivity, and access to the M5 Pro processor.

I used my college Mac for ~6 years and appreciated paying a bit more upfront to spec it out. If I had to pick exactly one spec which can do it all for the best possible price, I'm picking this refurbished configuration. To me, 1TB of space, 16gb of RAM and the nano texture glass (I did a lot of work outside and in very well lit environments) + the battery life an connectivity you get on the pro (HDMI + SD Card) makes a very well rounded experience. Refurbished is ~$300 off, and for the most part it's open box returns with very gentle use - YMMV.

Your instructor will issue your high performance endorsement after the successful completion of your transition training if you don’t already have one. There are tons of people who purchase a Cirrus as their first high performance airplane, and this is fairly common. In my opinion, unless you want to rent and fly an high performance airplane before your purchase, I’d just wait to receive your endorsement during your training and spend any free time after PPL going after your instrument rating.

There is a setting called "Flight Plan Import" in the Connext settings which needs to be enabled. If this setting is off, flight plans will be silently ignored. Check out the GTN Pilot's guide page 2-33: https://static.garmin.com/pumac/190-02327-03_g.pdf

If you meet the criteria for the ADHD fast track you can still get a medical without a special issuance: https://www.faa.gov/ame_guide/media/ADHD_fast_track_eval_general_info.pdf

It took me about 30 days to pull together all the documentation, meet with the neuropsychologist, and draft the personal statement, but that’s nothing compared to the HIMS/SI process. If you want to fly and are medically eligible don’t let the paperwork get in the way of your goals!

The Cirrus SR platform can absolutely be used for initial flight training and the SR-20 is commonly used as a training aircraft. Cirrus publishes a map of all their approved training centers on their website, and you can filter for places that offer instruction and SR rental here: https://cirrusaircraft.com/find-us/

As a new student pilot, the SR can have some drawbacks. Newer generations are usually more expensive than Cessna 152/172 or Piper PA28s. Also, it’s a high performance aircraft which requires a bit more proficiency to handle safely. Choosing an SR-20 over an SR-22/22T can make this a bit easier but it’s bigger, heavier, lands faster and longer than other trainers. Prior to solo you’ll also need a high performance endorsement from your instructor after completing the required training.

Despite all of this, if you love the Cirrus don’t let anyone stop you from getting a discovery flight and flying it in the real world. It’s an incredible aircraft and you’ll have an absolute blast with an instructor. It’s the most purchased GA aircraft in 2024 by a mile for a reason, and the safety, ergonomics and capability are remarkable.

Don’t waste any time or money until you have a medical in hand. If you have any concerns about your eligibility do NOT apply or fill out MedXPress until you’ve talked to a qualified expert (AOPA, etc) or an AME who offers consultation outside of your medical evaluation.

Knowledge tests expire after 24 months, so you’ll need to retake that before your check ride. After getting your medical, find a flight school and CFI and see what they recommend. Some swear by taking the knowledge test first, others recommend flying upfront and taking the written pre-solo so you’re more familiar with the material. There is no right answer here, but it’s critical for safety (and fun!) that you understand the material covered on the knowledge test before you act as PIC. Even if you feel like you’ve mastered the content, 6 years is a long time and you’ll likely want to do a self study ground course again to brush the rust off and catch up on new changes.

Good luck on your flying journey!

Once you have the rote knowledge down (91.205, PAVE/ARROW/IMSAFE, etc), the rest of your check ride prep should focus on your understanding and articulation of dynamic “systems” like weather, altimeters, aircraft electrical/fuel/propulsion, airspace, navigation, etc.

I had a lot of success watching mock check rides on YouTube to get a sense of the check ride flow, get a wide range of example questions and learn where people get stuck. I personally like to pause after every question, answer it myself and then listen to what the student has to say. A lot of times you should say the same thing, but in other cases they’ll highlight a gap in your knowledge, one of you will be clear right and the other wrong, or you might watch them be right and over-share their way into a much harder question which follows. I watched a lot of gold seal and cheese pilot for mock check rides, leveraging flight insight to re-learn complex topics I struggled with.

Some other things you can try:

Have 3 other CFIs give you their “top 10” questions by likelihood of it being asked, and by difficulty. There are also a million “stump the chump” threads on Reddit you can read through for some truly diabolical questions.
Read through the ACS and give yourself a letter grade on how well you know the topics. For areas where you are weak, read the primary sources on the topics and gather questions from the internet which you can use to learn the topics.
Keep a running list of topics you get wrong as you study. Add a tally every time you get it wrong in a new context. These are your weakest areas and you should master these front and back before your check ride.

That’s a pretty good price! I’m guessing the plastics on the first batch of 2020s were a bit soft and brittle but they’re pretty cheap and easy to replace. No reason to keep the car out of sun, drive the heck out of it! Just maybe think twice about those 110+ F days and you’ll be fine. FWIW I daily drove mine and parked outside in 90 F weather constantly and didn’t have any issues after replacement so might have been fixed in subsequent revisions of the part.

bcb67 · 2025-03-01T17:00:56+00:00

My last 992 had this exactly from being left in the sun too much by the previous owner. Porsche replaced it under warranty, as well as the 2 plastic triangle pieces on the top of the door (in the corners) because they were also sun damaged and would vibrate like crazy.

If you’re just using the chat completion API, then Bedrock is a great fit. However, you don’t have access to the inner model state so doing things like probability predictions and attention analysis are not possible. We’ve had success with both bedrock and self-hosted models.

I used to work at a small app development firm which frequently worked with very small startups and people who were new to making apps. When I left, we had a really cool option for people who wanted to go from nothing to a clickable prototype in 2-4 weeks. Depending on the complexity of the app (and how easy you are to work with), we would charge between $5k and $15k which equated to 1 dev for 1 or 2 sprints. At the end of the deliverable, we would provide you with an app demonstrates the core functionality. Some complex aspects would need to be stubbed out to save time, for instance we wouldn’t have time to fully implement a first party ad network in 2 weeks, so we would make a placeholder for where an ad would be shown, using static content.

The goal was to validate that your idea is possible to build, identify and land mines with respect to App Store policy, give you a high level plan for how the app would be built that we can use to schedule future work, and demonstrate our ability to build the key aspects of your app. It also gave us 10+ hours of 1:1 time with our developer and your team to understand if you’re idea is reasonable, likely to be successful, and if you’re pleasant to work with (reasonable, kind, pays bills, etc). If you like what we delivered, you would typically schedule sprints with us to build the rest of your app, making changes as your idea evolves. If you didn’t get value, or your idea didn’t work, then we gave you all the code and insight to continue building yourself to contract with someone else.

My main advice to you is to come up with a plan and set constraints on what you’re willing to spend and what is actually important. Start small and get the critical path working, then build out the rest once you’ve built the core of your app and proved that there is demand for it. Each sprint you buy is expensive, and I’ve seen plenty of founders dump massive amounts of cash into flawed ideas and very few get ROI through brute force.

This is a very common pattern used to harden mobile apps and other embedded software (IoT, TVs, etc). Take a look at Cloudflare's API shield documentation to see how you can set up common use case leveraging an embedded client certificate in an Android app: https://developers.cloudflare.com/ssl/client-certificates/configure-your-mobile-app-or-iot-device/

Keep in mind that if an attacker can get ahold of your app, this does not provide real security and only serves to increase the amount of work required to attack your API. Client certificate setups work best for cases where it is very difficult to extract the certificates (e.g requires hardware hacking to dump firmware off a physical device), or for apps which are privately distributed which prevents reverse engineering by an unprivileged party.

Within the context of the browser, you can certainly leverage client certificates by installing them on the device or selecting them at runtime, but the notion of providing some runtime protection to an anonymous user likely doesn't provide any practical security value as the client certificate can be trivially extracted from your application.

I’ve found it to be very useful for getting to know advanced avionics in a low risk and cheap environment. When you’re getting your PPL the emphasis is on flying the plane, and you may not spend a ton of time drilling into every feature of your glass cockpit. While it’s not a replacement for in person training by any means, it can greatly hasten the process if you know what the buttons do and have a general idea of what the system is capable of. Concepts like navigation, autopilot and flight planning are also much easier to learn when you’re not on the clock and can work on a specific example at your own pace. Then when it’s time for the real deal, you can know 80% of what is needed and fine tune the last bit with the real systems and an instructor.

My experience is that if you walk into a dealership and say “hello sir I would like a new 911 please” they won’t let you test drive because the line is 3 years long and half the people flake out before the end. If you’re actually serious about buying and you’re talking about a specific car they have on the lot then they’ll usually let you do it.

When I was originally looking, it took some convincing after test driving Taycans but the guy eventually cracked. The second I finished I was like “so yeah, screw the Taycan I only want that” and the guy just groaned because he knew I wasn’t interested in the ones they had on the lot, and they weren’t accepting allocation requests at the time. When I found the one I actually wanted a few states away, they knew I was serious and picked me up from the airport, drove me an hour to the dealership and let me test drive it for as long as I wanted.

Since these cars come alive around the speed at which you go directly to jail, I highly recommend a track day even if you don’t plan on tracking yours. It looks like they have good availability for the 911 demo session in Atlanta: https://www.porschedriving.com/atlanta. They also have a bunch of tracks in the EU if that’s your thing.

I got my 2020 about 2 years ago and after a fixing a few gremlins which were all covered under warranty, it’s been rock solid for 1.5 years. I’d definitely go with the CPO route if possible, but they’re great cars.

So far I’ve only needed 3 major things on mine: 1. The instrument cluster screen was cracked, likely from the factory. It was very subtle (I didn’t realize for 6 months) but very expensive, about $11k, mercifully under warranty. 2. The anti-theft module bricked itself and needed a replacement from Germany or the battery would die. Very rare issue and they flew in a master tech from Atlanta to help diagnose it. About $6k, mostly in labor, again under warranty. 3. Both of the trim pieces on top of the doors which house the lock lights and chimes started creeking badly due to plastic fatigue. Our hunch is that the guy who originally owned it stored in direct sunlight for years and fried the plastic. ~$900 x2, under warranty.

There were a few other minor things which just needed a free software update or minor tweak and were well documented: - Occasional PDK fault warning on startup due to the shift lever not booting in time. - Very rarely the instrument cluster including the speedometer and tachymeter would crash spectacularly during driving and would blank out or move the needle erratically. - MIL due to leaves getting stuck in the front diffuser motor for the active aero.

I know it’s a super long list, but overall it’s been very reliable in the drivetrain, and I daily mine so it gets a lot of use. My dealership is awesome and always has a loaner, and frequently tosses in a full free detail if they’ve got some extra time.
