I woke up at around 4am, thought “I wonder if PS5 preorders are open yet”, went to amazon, see that preorders are indeed up, one-click purchase. Go back to sleep. Got it on launch day.
Also the whole idea of the devil torturing people who didn’t follow god’s rules makes no sense. The devil is supposed to be an angel who was kicked out of heaven for opposing god. If anything he should be welcoming to sinners.
The argument is that you cannot really know. You don't know everything a person did. You don't know the motivations with which they act. You cannot look into their heart.
Yeah, we shouldn’t judge Hitler. Sure, we know he had millions of people killed, committed genocide and wrote a book detailing his exact motivations, but you cannot look into his heart and don’t know everything he did, so we should not judge him. He might just have been misunderstood and actually a really nice guy.

You don’t need to know everything a person did to judge them. Good deeds do not erase bad ones.
It us solely the company's responsibility to ensure each package is labeled with the correct weight, not the consumer to tolerate excuses like "measuing errors" whether they're valid or not
The measuring error is on OP’s end, not the manufacturer.
Scales used for commercial purposes, such as weighing the amount of product in a package, are regularly calibrated and checked. Messing with the calibration is considered an economic crime and comes with very harsh penalties.
The chip in a passport or ID card is not a simple data storage device. It's more like a tiny computer that the reader talks to. This is unlike a simple NDEF tag that you can easily clone, there are several layers of protection.
First, you need a key to even access the chip. This key is derived from 3 pieces of information on the document: the document number, the date of birth and the date of expiry. The idea is that to get this data, you already have to be looking at the data page of the passport, that is: to access the privacy-sensitive data inside the chip, you already have to be able to look at that same data printed on the page.
This data then goes into a key derivation function. Some handshake messages are exchanged which I won't bore you with, and both the chip and the reader should at that point be able to derive another key that will then be used to encrypt any communication between chip and reader. There are actually 2 different mechanisms for this, the older BAC mechanism (Basic Access Control) and the newer PACE mechanism (Password Authenticated Connection Establishment). The latter uses newer and even more secure crypto.
This prevents eavesdropping and ensures you cannot remotely read the document.
Once the connection has been established, the reader can request certain chunks of data from the document. This includes everything that is printed on the data page, as well as a higher-quality color version of the photo on you document.
The data that can be read from the document is digitally signed by the government of the issuing country. You can verify this signature against a list of trusted certificates. Only the government that issued the document should have access to the corresponding private key and as such you cannot forge this data (unless you are able to break certain cryptographic standards, but if someone can do that we have bigger problems than fake IDs). This is called 'passive authentication'.
Now, if you get your hands on someone's passport, you could still copy the data, you can't modify it, but you can clone it. To prevent this passports also have a clone detection mechanism. Again there are multiple versions of this, but the most basic form is called Active Authentication. Part of the data read from the passport, is a public key. The chip in the passport has the corresponding private key, but there is no way to read this key. You can confirm it's not a clone by sending a piece of random data to the passport and asking it to sign that data with its private key. You then use the public key to check the signature and confirm the document is in possession of the corresponding private key. You can also confirm the authenticity of the public key, because that is also signed with the private key of the issuing government.
Now, theoretically you could try to extract the private key used in clone detection from the physical document, you would need some extremely advanced tech to do this, and the chips in ID documents have all kinds of physical protections against these kind of attacks. Maybe some intelligence services would have this capability, but it would only allow you to clone a document, not forge one.
Chip cards wouldn't work online unless we had some sort of reader
Good news then. We do have a reader. Chances are you are looking at one right now.
Almost all passports have chips (with the exception of a few developing countries, but even they are starting include them) and a lot of ID cards do as well (most ID cards in Europe already do and new ones are required to have then).
You might not see them, as they are contactless chips. They can be read by the NFC reader in your phone.
If you want to try it, search in the App Store or Play Store for an app called “ReadID Me” and test it on your passport.
Tell me you use Windows without telling me you use Windows.
Meanwhile I just reboot my Mac without bothering to save anything and everything just restores as it was, even new documents that were never saved. It works so well I don’t even think about it anymore.
They may build dedicated PCs for training, but those models will be used everywhere. All computers will need to have hardware capable of fast inference on large models.
Unified memory is also huge for performance of AI tasks. Especially with more specialized accelerators being integrated into SoCs. CPU, GPU, Neural Engine, Video encoder/decoders, they can all access the same RAM with zero overhead. You can decode a video, have the GPU preprocess the image, then feed it to the neural engine for whatever kind of ML task, not limited by the low bandwidth of the PCIe bus or any latency due to copying data back and forth.
My predictions: Nvidia is going to focus more and more on the high-end AI market with dedicated AI hardware while losing interest in the consumer market. AMD already has APUs, they will do the next logical step and move towards full SoCs. Apple is already in that market, and seems to be getting serious about their GPUs, I expect big improvement there in the coming years. No clue what Intel is up to though.
I think the opposite is true. Discrete graphics cards are on the way out, SoCs are the future. There are just too many disadvantages to having a discrete GPU and CPU each with it’s own RAM. We’ll see SoCs catch up and eventually overtake PCs with discrete components. Especially with the growth of AI applications.
For example: when I start a movie, the lights in my living room dim or turn off automatically. Sure, I could get up and do and set several lights manually, but I would probably not bother and watch a movie in a lit room. When I stop or pause the movie, lights go back to the normal setting.
If it’s dark when I get home and I open the front door, it starts the default lighting program. Sure I could fumble for the light switches in the dark, but it’s another convenience.
It’s almost as if Microsoft is a software company at heart and just wants to sell as many copies of their software as possible.
