"Just ignore the lidar in situations where lidar and vision conflict and you have the original decision." Then why have lidar? If it's only purpose is to agree with vision or you just discard it, then why even have it?

I have, quite often. :) I've always gotten the answer from officials "if you aren't competing with local workers, you're fine". As always, depends on the country. Further down the source I just cited: "Examples

It's totally legal everywhere I've visited (and I don't know a country where it's illegal). Work visas are a thing because countries want to control the ability for foreigners to compete with locals for local jobs. Canad

It's not guaranteed to be atomic in failure conditions. Also, the biggest difference between Redis and Geode would be the "distributed" part, which involves maintaining these guarantees across a cluster of machines (which Red

Sometimes, just maybe, the priority isn't to build something from scratch (however simple), but rather press a few buttons and move onto something more important.

That was my interpretation of your comment, but I'm still not sure I follow. In my understanding, by using RAID 0, any single disk failure will brick a node. Each node would then have 3 disks that are ticking time bombs (multiplying

by jrallison 12y ago
A few reasons off the top of my head: 1) We're still interested in the nodes being as reliable as they can be. With RAID 5, we need two simultaneous disk failures to brick a node. With RAID 0 (to increase usable disk space), any of the

With a replication factor of 2 (for fault tolerance), it's ~4.5 TB. FoundationDB requires SSD drives, which the best we can get efficiently in our data center is ~670 GB of usable space (3x480GB raided). 12x670 = 8040 GB We try to keep

Multi-key transactions means coordination. Coordination is not cheap. You'll be paying a hefty cost somewhere.

Don't know much about RAMCloud, but from the description: "Many more issues remain, such as whether we can provide higher-level features such as secondary indexes and multiple-object transactions without sacrificing the latency or

Absolutely. Choosing the proper data model based on your access patterns is one of the best ways of keeping FDB performance high by reducing the likelihood of contention.

We've been using FoundationDB in production for about 10 months now. It's really been a game changer for us. We continue to use it for more and more data access patterns which require strong consistency guarantees. We currently st

Of course. I wasn't challenging the bond rating, just the parent's notion that user engagement isn't a valuable metric for Twitter.

by jrallison 12y ago
It's not hypothetical. Twitter has significant revenue. When revenue is generated from eyeballs (ads), then yes, number of users and engagement is a valuable metric (yet not the only one).

It won't do well, but at least Antirez is up front about the shortcomings. The article itself states that Redis Cluster will lose acknowledged writes during partitions (no P), will be eventually consistent (no C), and won't be ava

Of course, which was the main driver to moving to a compiled language. We just happened to choose Go :) I've done a lot of Java and C++ in the past, and wasn't looking to go back to either of those.
