A CEO can do many things, but they generally don't design, develop, test and fix products. I have no personal affection for Elon Musk, just wanted to point out that the actual things we all use are products of genuine hard work by lots

Tesla is also thousands of brilliant engineers that transformed the industry, and not just one guy who tweets a lot.

High-level targets (for whom this mode is specifically advertised) are likely aware of the dangers of installing apps. Enterprise-signed apps require an explicit (and non-obvious) action from the user when running for the first time.

ARM Windows builds run fine on Apple Silicon via Parallels. Windows also has a built-in x86 translation layer, so it is able to run most programs.

In some sense, pain is also a mental construct — just some electrons bouncing around in one's brain, yet it feels very much real.

Alternatively, the charging infrastructure needs to evolve. Even considering the currently available technology, imagine having 150kW chargers in place of every gas station that we have right now. Install ~20 chargers in the most busy locat

Parallels run a similar thin wrapper on top of the OS-provided VM API which looks somewhat like: vm = createVM([device list]); vmWindow = createVMWindow(vm); vm.run();

Theoretically, can this scheme be turned into a generic O(N) key-value retrieval for non-static content (in this example — supporting adding, removing and replacing articles without re-encrypting the whole database and re-sending the client

> Graphics is a bit better than 20 years but nothing "wow" Maybe 10 years — in which case the answer is: graphics nowadays is mostly bound to the current console generation. GTA 5 was released almost 10 years ago for PS 4. Unch

Correct, but with everything in plaintext one just needs to read a file stored somewhere in a database. With encryption, one needs to perform an active attack.

We do, but that would require the company to lie about what they are doing with the app. At Twitter's scale it's very possible that someone would notice and leak that. The goal as I imagine it is to go from "Hundreds of Twitt

Almost every encrypted app allows users to check their keys via QR code scanning or string comparison. If twitter adopts encryption, I hope they will let users do that. At this point the same entity controls both key distribution and the me

It doesn't look like Matrix has reached the point where there is any significant network effect. What I'm saying is that they are building a product, and the protocol is just one component of that product.

Yet Matrix is gaining traction while XMPP is not. Maybe the key was to have funding, build and run a reference server and quickly iterate with a reference client for all major platforms.

Are there any real websites using IPFS at the moment? Anything I find is usually a tech demo that takes a minute to load. IPFS could be what hypertext was for the web, meaning that anyone can self-host their own stuff, but so far it’s been

Looks wonderful in 2022: "Each scene is 100KB in size. It may take up to a minute for the scene to load, so please be patient."

The world is massively unfair as it is. Would anyone even notice already "privileged" societies becoming a little bit more privileged? Who knows, maybe our IQ 120 overlords will be kind to make the tech available for everyone else

Not really. TOR is specifically not safe against a global passive observer, which the (supposedly) good guys are.

I’ve always been interested in CG. Back in the day, I played with OpenGL 1.x, D3D5, lived through the introduction of shaders. Now I’m toying with Vulkan and it’s incredible how simple it feels compared to the old-school APIs. Everything ba

If I’m reading this correctly, file blocks in ipfs are individually addressable https://docs.ipfs.io/concepts/how-ipfs-works/#directed-acycl...

It would be interesting to understand why ipfs was so slow in prior experiments.

Don't forget that any of the M1-family chips are absolutely crushing the competition in single-core performance.

No, Apple already modifies uploaded binaries before storing them for distribution. In some cases Apple even compiles the binaries themselves (if the developer chose to include the LLVM "bitcode" when submitting the app).

Debug symbols are stored separately on the developer’s computer (and may be uploaded to Apple, but that’s optional). Including symbols in the App Store binary is practically useless.

There are software engineers who sometimes write code that’s not perfect.

It's clearly a personal preference. Many people adore old historical districts of Europe, dream of living in Paris or Florence. Some can't stand the buzz of the city and prefer to have a place in the countryside. Some just like mo

It didn't work when I tried to pass through a virtualized GVT instance in Catalina a couple years ago. Although this all will not matter once macOS becomes exclusive to Apple Silicon.
