Orion is actually pointless, I don't understand why the mission goals are valuable. Partial success would be meaningless. Success is meaningless.
Starship in contrast has a variety of meaningful objectives. Even if Starship only achieves proving that cryogenic fuel transfer in LEO is possible that's a valuable mission goal in and of itself.
If you really think "the whole moon thing is pointless" NASA is pointless.

There's more to NASA than Artemis! NASA's robotic spaceflight programs generate extremely high science return at relatively low cost. Missions like Psyche, Europa Clipper, and Dragonfly are humanity's real explorers.
And their aeronautics work is valuable as well. Low-boom, etc.
Orion doesn't seem operationally or financially capable of launching more than once a year. It's not that they don't want to do test flights, it's that they can barely do anything.
So far, Isaacman's competence has mostly consisted of (rightfully) throwing is predecessors under the bus. The real test will be if there are problems on his watch, but also it seems likely the result of having backbone will not be good for Isaacman and sycophants will end up running the agency again.
How? He essentially said that the program would not work as designed and would probably kill people. That is both true and necessary to say in order to fix it--these are exactly the lessons NASA (allegedly) learned from Challenger.
The GGP said he threw people under the bus. That's different than making changes to a program.

I don't believe you can know that. Saying it with assurance - by Internet randos or by the NASA administrator - is more a signal of a lack of analysis. Other people aren't idiots and complex technology issues aren't that certain - those are self-serving fairy tales.
It's a single XML file. Zip sounds like the worst of both worlds. You would need a new schema that had individual files at some level (probably at the "row level.") The article mentions SQLCipher which allows encrypting individual values separately with different keys. Using different keys for different parts of a kdbx sounds ridiculous, but I could totally imagine each row being encrypted with a compound key - a database-level key and a row-level key, or using PKI with a hardware token so that you don't need to decrypt the whole row to read a single field, and a passive observer with access to the machine's memory can't gain access to secrets the user didn't explicitly request.
ZIP files can have block-like relatives to the SQLite page. It could still be a single XML file and have piecewise encryption in a way that change saving doesn't require an entire file rewrite, just the blocks that changed and the updated "File Directory" at the end of the ZIP file.
Though there would be opportunity to use more of the ZIP "folder structure" especially for binary attachments and icons, it wouldn't necessarily be "required", especially not for a first pass.
(That said there are security benefits to whole file encryption over piecewise encryption and it should probably be an option whether or not you want in-place saves with piecewise encryption or whole file replacement with whole file encryption.)
My impression is there's a definite shortage of GPUs, and if OpenAI is more reliable it's because they have fewer customers relative to the number of GPUs they have. I don't think Google is handing out 429s because they are worried about overspending; I think it's because they literally cannot serve the requests.
This sounds very plausible. OpenAI has hoarded 40% of world's RAM supply, which they likely have no use for other than to starve competition. They (or other competitors) could be utilizing the same strategy for other hardware.
Which is worrying, because if this continues, and if Google, who has GCP is struggling to serve requests, there's no telling what's going to happen with services like Hetzner etc.
I believe OpenAI's purchasing is somewhat overstated, it definitely has no effect on Google's current ability to serve Gemini requests, but it is obvious that there's a shortage of most components, and it's also obvious that even internally Google is having to make hard choices about who to let use GPUs when.
I definitely think OpenAI likely has less use for GPUs than Google. Google has $300B in annual revenue vs. $20B for OpenAI. Even if you assume 100% of OpenAI's revenue is going to renting GPUs and they are taking a 50% loss there's still a lot of room for Google to be profitable and spending more money on GPUs, and not have enough GPUs. Google also just has a wider variety of models to train and run, from Waymo to Search to whatever advertising models.
OpenAI is dependent on same hyperscalers (most specifically Microsoft/Azure) as everyone else, and even have access to preferential pricing due to their partnership.
A better explanation is to point out that ChatGPT is still far and away the most popular AI product on the planet right now. When ChatGPT has so many more users, multi-tenant economic effects are stronger, taking advantage of a larger number of GPUs. Think of S3: requests for a million files may load them from literally a million drives due to the sheer size of S3, and even a huge spike from a single customer fades into relatively stable overall load due to the sheer number of tenants. OpenAI likely has similar hardware efficiencies at play and thus can afford to be more generous with spikes from individual customers using OpenCode etc.
I would guess the biggest AI product on the planet is Google's Search AI. Although even that might not be the case, unless your definition of AI is just "LLMs" and not any sort of ML that requires a GPU.
The funny thing about Facebook is that it's got a perfectly good social network in there, I think the only one that exists. In the menu is "Feeds" which is what you want. It only shows friends and followed things. If they made that the default when you go to facebook.com I don't think I'd have any complaints feature-wise, though an ad-free option would be nice. It's a genuine social network.
Of course, then there's the question of who decides how and what is moderated, and the question of who can access your data, and Facebook definitely leaves a lot to be desired in that area just in terms of Meta not being a particularly trustworthy entity to have control of those decisions.
Wow, I did not know about this Feeds page despite being a daily FB user for 20 years (yes, to the ridicule of most people, I know). Thanks for pointing this out. I wish this was the default homepage or at least a way to set it as default.
Each feed has a unique URL, so you can bookmark it in your browser. For people using Facebook via native mobile apps, my recommendation would be to stop and use a browser.
Thankfully, since then, Chrome and all other major browsers now ask the user for permission before letting websites send requests to localhost or any local IP addresses. Obviously some users may click through that, but it prevents the behavior from being invisible to the user at least, and gives them a way to say no.
PS: I still recommend never installing Meta apps on your phone.
PPS: There are legitimate uses of this functionality, so as a web dev I'm happy the functionality wasn't silently blocked. This gives an opportunity to explain to the user why the permission is needed if the use is legitimate. Would be nice if it could be further scoped though.
Goes to show how much my 300 friends use Facebook, I had to scroll at least 3 pages before I found a post from my grandma in law about her dog, and that was all for the next few scrolls. Everything else was followed pages that I actually don't care about and ads.
Wechat moments show you the things that your contacts post. There are theoretically ads too, but ever since they forcibly converted me to a US-based account I don't get ads because no one is interested in advertising to me.
It's too bad; I liked seeing the Chinese ads.
Comments on wechat follow the Maplestory system where you can see comments (on anyone's posts) from your own contacts, but not from other people.
They fired a lot of people at the FDA and also deliberately made it harder for the FDA to regulate. That is likely to cause problems for our food and medicine supply, the FDA has been the world standard for a long time.
It's interesting to think about this in terms of something like Ars Technica's recent publishing of an article with fake (presumably LLM slop) quotes that they then took down. The big news sites are increasingly so opaque, how would you even know if they were rewriting or taking articles down after the fact?
This is typically solved by publishing reactions/corrections or in the case of news programs starting the next one with a retraction/correction. This happens in some academic journals and some news outlets. I've seen the PBS Newshour and the New York Times do this. I've also seen Ars Technica do this with some science articles (Not sure what the difference in this case is or if it will take some more time)
On their forum, an Ars Technica staff member said[1] that they took the article down until they could investigate what happened, which probably wouldn't be until after the weekend.
I'm not asking how you solve the problem of publications making mistakes, I'm asking how you know they're rewriting articles if there are no third-party records of article contents. You're talking about publications acting in good faith. I'm talking about publications using paywalls to make it easier to lie.
