Not really, just like it's not worth it having any power supply embedded into a power outlet. It's also a bit dangerous, it can malfunction and burn your place to the ground without triggering circuit breakers. Also USB-C power in

Well, can you imagine a future where a billion battery powered cars is a possibility on this planet? A billion electric bikes though is not that crazy.

Billboards are pretty different. It's like if websites had a separate page with ads where you go if you are curious or bored, not doing anything important. And people suggesting something is on the whole another level. They have empath

I think he's talking about the freedoms that ads take away. You don't ask to see the ad or the category of products it advertises, but someone found a way to show it to you anyway through some deliberate automated system, trying t

Does it really matter what an official justification for planned obsolescence is?

Well, there is always a market for a new OS as they all are so complex and have so many baked in assumptions, that they cannot possibly do well on the variety of use cases that people need computing for.

But SD cards, CF cards, eMMCs, USB sticks - unless enterprise graded and claim otherwise, all have either very primitive wear leveling in their FTL or none at all, it's only SSDs that have full blown log structured algorithms.

Why would that be a terrible idea? If someone has unauthorized access to my PC and knows my password from the account, he can log in and pay my bills and only the usual amounts, as paying too much would trigger 2FA.

by zzzcpan 7y ago
I guess it depends on the country and the bank. My bank, for example, does mandatory 2FA for 15+ years and uses some anomaly based approach to decide how aggressively to ask for 2FA, like if you send money somewhere unusual, it does phone c

No, it's atomic. It's just not important if separate databases are not atomic to each other when you recover from backups, you will still have data loss and an inconsistent state. I.e. things that should be in the database missing

Strong consistency is not what you think then. You can only do stale reads from backups.
529.
by zzzcpan 7y ago
Backups are fundamentally limited to eventual consistent, there is no need for databases to be synchronously replicated for backups. I mean splitting database has no effect on backup consistency, although a more decent way of dealing with i

Nginx doesn't cache files by default, but it has a file based caching module and a file based store module that can be used to retrieve files from backends and cache on local filesystem.

You can get a point read with just a single aligned random I/O operation on disk with this. I don't see how a B-tree based storage can compete. And even more optimizations are possible, like grouping objects often accessed togethe

Theoretically there could exist filesystems that can do well on thumbnails and small files, but in practice this has never been true. Databases are typically better at this and specialized solutions can get you even farther, like over an or

Unlike in dropbox case, this is something people with engineering degrees that often include physics and material sciences can actually calculate.

Not how it works. It's not enough to try something, you have to share the knowledge with the community, otherwise there will be no progress until someone else willing to share the knowledge tries the same thing again. So, it's as

It's not an experiment that can yield anything or teach us anything if there is no paper and no data. A fraudulent startup maybe.

To summarize his videos: solar roadways were never feasible even in theory with quick back-of-the-envelope calculations and all of the known solar roadways projects in the world have failed or are nearing failure.

Await is just syntactic sugar. You do not really await anything. What actually happens is an event handler gets called on an event, where it sets up more event handlers for more events and so on. This is the essence of asynchronous programm

In cooperative multitasking you can program when to give up control, not when it is regained. The regaining part is unpredictable. Which introduces a lot of non-determinism to deal with and overhead.

It goes deeper than that. There is plenty of research showing that shared memory multithreading is not even a viable concurrency model. The premise that threads are fine and simple is just false.
