Yes and as memory increases more of the high bits are used as actual address bits. X64 started with 40 physical bits. We’re now at 48.

That only ensures the programmer fixes the pointer before dereference. Tagged pointers that don’t make it to the bus are still a compatibility problem. It means malloc() can’t return an address overlapping the tagged bits.

An elliptical orbit would require the perigee to be even closer to the earth further increasing drag. It is possible for small fragments to potentially be moved to higher orbits (with counter balancing mass being moved lower) But the conser

Low earth orbit satellites decay very quickly. Without extra boost most satellites launched by these rockets will reenter within a year or two. On a wider note, I find the dramatic pessimism of our times rather unfortunate. It seems every

Back then I chose MySQL because of php-myAdmin. That and the fact there were so many more tutorials for it were the main drivers of the decisions. Proper foreign keys and transactions were nice, but who knows if this app would go anywhere

And then people would ex-filtrate data by toggling the numlock light programmatically.

Could you elaborate a little on why that's relevant? Is the extra money providing materially better education? Is it somehow impossible for Chicago to lower their costs?

Many people, myself included, see Nuclear as inseparable from climate change and green energy. We could dramatically cut our greenhouse emissions now, with technology we've had since the 1960s. It's really hard not to point out w

Cats are required everywhere, but in CA they need to contain much more precious metals to meet the state standards than they would for just the national requirements. Most automakers choose to standardize on CA emissions standards national

It was also how I found out that I could now have a whopping 2GB hard disk in my own machine - or that I could upgrade my 486 to a pentium with this cool new thing called the Pentium Overdrive. Computer mags were especially exciting becaus

That all depends on the contract with whatever service your using. It would be totally legal for the cab driver to make you sign a contract making you liable for any damages. I'd be very unlikely to sign for a cab ride, but I might i

The real magic of Optane DIMMs is their persistence. Using them as volatile memory mostly defeats the purpose unless you need A LOT for some reason.

I'm not OP but it comes from the fact that Spectre is a very specific bug, but is colloquially used to refer to all speculative execution bugs found after as well. So its true that AMD is susceptible to Spectre; However, the mitigatio

The lower the humidity the more efficient evaporative cooling is. These data centers don’t use traditional AC.

The Redis version does not thread query parsing. Its limited to only IO which is why its performance is much lower.

by jdsully 7y ago
Higher traffic loads result in latency increasing. This benchmark covers the maximum load so latency will be much higher.

No offense taken. KeyDB has different goals than Redis so you’ll see us try things Redis might not. I’m willing to make the code more complex if it makes the user’s life easier in some way.

If the perf isn’t needed we also have Active Replication, subkey expiries, and S3 integration. Multithreading is how we got our start and the reason most people use us though.

by jdsully 7y ago
Sorry we didn’t improve your use case. If you are bottlenecked by Redis I would be curious about your workload.

KeyDB provides that guarantee via a lock. However that does mean long running scripts don’t benefit from the multithreading. Ditto for modules. The goal is 100% Redis compatibility so I can’t compromise on atomicity.

A recurring debt forgiveness schedule would do just that. If all debts expired after 10 years lenders would be much more cautious.

By that logic the Pentium 3 was a 128-bit CPU. Vector width isn’t how these things are measured because its much harder to make a 128-bit ALU then add two 64-bit ones.

AVX512 is not comparable to 128-bit native. AVX/SSE are split into lanes of maximum 64-bits. You can not compute a 128-bit result only multiple 64 bit ones in parallel.
