It’s not removed from your device. If you have it, you have it. You just can’t download it from Apple again, and you won’t get updates.

How fast is it? SQL on top of KV is tough to make zippy due to metadata and scanning issues.

Also curious what updates are coming to the older box. Presumably it will run a tvOS light, or something?

One issue here is using tax policy to incentivize investment in higher education by penalizing institutions for NOT spending huge endowment windfalls on higher ed. You don’t tax Harvard the school like you tax a corporation. You tax Harvard

I'm actually going to be discussing this at Strangeloop next month. http://www.thestrangeloop.com/2015/all-in-with-determinism-f... VoltDB is actually a bit simpler with what it promises, full serializable ACID fo

Yeah, VoltDB's not free for many purposes; neither is it Ellison expensive. Factor that into your decision. But at least the costs are up front. In both the VoltDB case, and the Kakfa/Storm/Cassandra case, licensing is probab

Before you start plugging lots of systems together to solve this problem with a gaint hot mess, take a look at VoltDB. It basically is the system the article describes, but faster, more integrated and tested as a whole. It'll save you

This might be overdoing things a bit. FoundationDB was a rigorously tested KV store with strong consistency (uncommon for such a product). Yes, that talk from StrangeLoop was great, but there's two common misconceptions here: (What fol

My experience is that the learning curve is steep but the payoff is large. The Apple Cocoa/AppKit/CF libs are hefty things to get started with, but man do they make some hard things easy once you get the hang of it. They also tend

Degree matters. As biased toward certain groups as the US justice system is, it still resembles the rule of law.

Seems to me that robot stuff is getting cheaper faster than wages are going up. If a robot can do the job, then another $6 an hour probably isn’t all that different. Might as well pay people a living wage for hard work in the meantime.

> You could also shut down definitively, for example if the system is corrupted and cannot restart after a partition. There is no inconsistent history in this case, just complete unavailability (you could also claim being CP). This is pr

by jhugg 11y ago
I don't understand. When you run into partitions, you need to make a decision, risk being inconsistent or shut down. Ignoring the problem is just choosing inconsistency by default. You haven't actually gone CA.

Current VoltDB, former Vertica dev here. The simplest answer to this question is basically to argue that the architecture and implementation matters, and that Oracle (and others) are often bogged down by compatibility constraints and conser

Yeah, as Ryan said, no split brains possible in VoltDB for quite some time. We originally had split brain protection something you could enable for cloud deployments, but figured it wouldn't be worth the tradeoff if you had 5 machines

One of my favorite things about VoltDB, as one of the people who built it, is that its serializable isolation is actually a fundimental part of the architecture. Many of these systems get slower as you turn up the isolation. VoltDB is faste

I mean... sure. Oracle doesn't OWE me anything. They can do what they want. But if they want a positive relationship with their community, they could not break compatibility with every Java release. I don't know if they care. At s

I have an automatic, and it's neat, but I'm not sure I like it. For $70-100, it's not the cost in dollars. It's more about how much tracking data the thing uploads. I'm a bit uncomfortable with it. It feels like the

Ugh. This is super annoying. You can only see this filter and the eligability if your default address is in the region. I live in a valid area, but often have things sent to work which is just outside the valid area. I wish I could see the

Is there a way to restrict my search to eligible items?
176.
by jhugg 11y ago
Yes. I know there are other ways to do simple counters. The counter-example broadly applies to multi-statement operations that feed the output of reads into writes, i.e. in general transactions. And yes, the defaults on many systems are low

It seems like the improvements here are OLAP focused, and welcome ones at that, but the docs and product, if not the marketing, seem to be moving away from operational workloads. From my interpretation of the docs, there are no "transa

Actually no. The key innovation is that data is stored in a memory friendly way, then logged to disk in an append-only, log friendly way. VoltDB can be fast and persistent; the catch is that your data must fit in memory.

VoltDB, like MySQL Cluster and several other in-memory system, uses snapshot checkpoints and logging to maintain power-loss protection. VoltDB is a bit different because of how it uses determinism + logical logging, but the point is that mo
