JIT translation has come a long way and MS plans to do exactly this with x86 software runnning on ARM in the near future. It’s not impossible that A12s with custom silicon working in concert with software JITing could provide a decent exper

Right… so if you’re up for some conspicuous consumption, you better shell out for the more expensive model.

I love having a camera with me everywhere I go. I love seeing something weird or amazing and being able to share that with my friends or family in seconds. There is value in not letting devices control us, but there is also value in shared

It says this has something to do with connecting to unsecured Wifi networks. That seems, amazingly, like something Apple testing might overlook. Who has unsecured networks these days? It also sounds like a bugfix that could come shortly and

It’s because in many parts of the world, people won’t buy expensive things unless there is some way for people to know you spent a lot of money and have the newest thing. I hate the red dot too. Already ordered my WatchDots.

He doesn’t really need a watch either then? If you concede it’s a gadget review for something you don’t strictly need, why not indulge him?

I use 27” 4k monitors with macbook pros running at 5k retina scaled down to 4k and it looks FINE. It doesn’t look as good as 5k, but WAY BETTER than non-retina. For about the third the cost, you get about 2/3 of the benefit.

Users want backups in resilient DB for the same reason RAID isn't considered a backup strategy.

1) There's no lag between VoltDB confirming to clients that a write has been committed and that write being on disk. Zero. 2) The way VoltDB does persistence is actually quite different than MemSQL. VoltDB is able to write deterministi

But the overclock is going to affect actual draw. Not sure by how much... possibly a lot.

> There is async lag to fsync in-memory data to disk, which is configurable, but obviously this is a trade-off with RAM based operations like any other database. As a VoltDB dev, I don't accept this. Performance and sync disk persis

I wonder how much more you pay in electricity costs over a Kaby Lake 7700K for example, which idles much lower and wouldn’t need to overclock.

We have a whitepaper here: https://www.voltdb.com/wp-content/uploads/2017/03/lv-technic... My brief summary comparison. VoltDB is a bit less general in some key ways. It tends to have the same performanc

I think that logical logging was an obvious choice given VoltDB architecture. It's totally possible there was a talk that was involved for somebody though. That said, we <3 determinism at VoltDB and rely on it to achieve what we ach

How many systems are out there that will run at YouTube/Facebook/etc scale without "huge amount of engineering resources to make it work"? Zero. Zilch. Nada.

I have young children. I’m not trying to prevent my kids from intentionally seeking something objectionable on the internet; I’m trying to avoid them accidentally finding things they’re not ready for (this happens). It’s rather amazing how

Batteries don't tend to degrade like they used to. The chips that charge and discharge them are a lot more sophisticated. Most batteries do well for 2.5-3 years these days.

The more I learn, the more I want this as a 3DS replacement. The TV aspect doesn’t interest me as much. It looks like it might deliver on that promise as they work the kinks out.

Hi Will. Thanks for the shout-out. I still think many of the arguments in that blog post hold up for non-embedded KV stores. I think you can mitigate a lot by aggressively caching metadata, but eventually you end up moving the SQL engine cl

I understand what he's saying. It's marketing. There's nothing wrong with saying it's CP, but since we control everything there's extremely rare P. Then he can show availability numbers (which he kinda does). Saying

I would expect more from Brewer. "CA except when there are partitions" is CP. It's not "effectively CA".

Note it’s not really “The Jepsen Test” as the tests are all a bit custom and different. Sometimes they’re looking to validate different claims. For example, Kyle integrated some serializability tests into the VoltDB Jepsen testing that woul

I love that you can just buy a CA and devices will trust the new owner. That’s not messed up or anything.

So you've got this thing that's of non-zero value. Because the company shut down, and didn't get acquired, it's probably still owned by a largish number of folks. Getting the right approval to sell it for a song would se
