OK, I was being sloppy in my phrasing (and probably thinking also)! Trying again: Taking your example benchmark, you aren't really calling any special methods that provide any hints for cooperative threading (to my untrained eye). Tha

I looked and your wrapper did look similar (and not obviously incorrect), but if you plan on publishing this benchmark, I would suggest including a comparison against raw Java code, for credibility's sake. I guess I'm really wonde

I noticed that you send the "native threading" case through your library as well. Have you compared to just using "naive" Java - Threads and a BlockingQueue? Also: if the Google patches for the user-mode threading are a

Even if I don't use the SDK, I greatly appreciate when the same company that writes the API also builds an SDK. APIs which don't also maintain SDKs - in my experience - don't understand the cost of making breaking changes, an

As Gogo is losing money, I think complaining that it is too expensive is curious. Yes, it is expensive, but the negative markup is much less than the airlines charge on baggage fees, drink prices, snack prices... Of course, it's not l

There may not have been a recent total outage of the kind that hits the news, but I would bet Moz are referring to degraded service (slow CPU/disk/network) that causes their application to fail (or their error rate to rise). I&#x2

Nothing is wrong with them trying, I just want to see them succeed in doing so. I was finding fault in their strategy for monetization, not in their desire to do so. I believe customers pay for support, not for the GUI that makes support e

Looks _really_ great: one of the prettiest dashboards I've seen, combining logs & metrics. However, it would be a lot more interesting if it was open source; because then it would get forked and applied for monitoring other system

Sometimes it feels like OpenStack suffers from the problem that there are too many cooks, and not enough people eating the (dog)food. So it's great to see Box getting involved in adding erasure coding: it's a technically interest

Wouldn't you get higher read throughput (2x for R1, less for R5) by reading the parity disks as well?

I thought this was going to be fixed when user namespaces were added to the kernel. I think user namespaces was merged early in 2013, but I haven't heard that it is now fixed. Is it now safe to give root inside an LXC instance?

Here is the patch (I believe): http://hg.openjdk.java.net/jdk8/tl-gate/jdk/rev/2c773daa825d I was quite surprised that we _always_ copy the array. I would have guessed that .substring(1) (all but the fi

I don't think that style of code is wide-spread in the real world; this feels like a total straw-man. Annotations are normally much better than any alternative we've come up with (e.g. XML), but the extreme case where you use eve

A nice project: Git is a wonderful version control system, but the git cli (the porcelain) definitely has some annoyances. I think submodules, for example, are completely broken at the CLI level. I don't think this project necessarily

I'd love to help (I opened KAFKA-1050 on the issue), and I even started coding, but I got stuck on how to deal with the rollback problem when a write isn't acknowledged by a quorum. I think it requires a "real" distribu

Hi there - I see you're Mr Kafka :-) I wanted to use Kafka instead of Raft for my project, but for my application I couldn't tolerate the (even highly unlikely) possibility of losing a message (when we lose all the nodes in the I

The idea of the log goes well beyond just real-time data (as the blog post describes, although the title does not). I think it might well turn out to be one of core building blocks of _all_ stateful systems. Amazon's Kinesis has for t

Offline is awesome; obviously because it means it works anywhere, but also I presume this means that all formula evaluation is now done locally, i.e. "instantly". I am pretty sure that before the server was involved in (some?) re

I was saying that the blog post is the best bug report I've ever seen. To extend the analogy: in my mind, the way you're treating it is like closing it as "INVALID" without any comment, which tends to annoy bug reporte

I would treat this as a great bug report. Aphyr has done a lot of work, showing that a (reasonable to me) formal interpretation of your gist produces catastrophically bad results. If you're unhappy with the formal interpretation of yo

Isn't the simulation sufficient? A proof that something works requires logic, but a single counter-example suffices to show that something doesn't work.

Definitely valid points! Personally, I hope that we end up with a shared-ownership model, and that the cars do park 10+ miles away if they are idle, but that this is amortized across a large number of commutes. I also hope that we use the

If self-driving cars become a reality, it is interesting to think of what happens to all this space & infrastructure. If the model is that we don't own cars, but rather share them like taxis, then there is no need for parking: the

Isn't this exactly how location is always done without GPS? Look at the strengths of all the radio signals we can see, and match against known locations? Admittedly it's previously been primarily cell-towers & wi-fi, not GPS

Personally I hate the "slide" animations when e.g. launching a new full-screen window. It takes about a second, but any keys I press during the animation seem to go into a blackhole (repro: full-screen chrome, open new window, st

I participated also, and enjoyed the hackathon itself. I wasn't expecting to win. I expected the winner to be someone that had a suitable product that was ready to launch around the same time as the hackathon was announced, and decid

Can anyone suggest why this might be the case (presuming that it is true)? It seems to be much more work to hide the image vs. simply deleting it, so I'm guessing that there is a reason...

I think this is an incredibly interesting approach, and I hope Seagate open it up a little more. If we could run some computation on the drive, that could be incredibly powerful. I can imagine that once these are SSD drives, paired with re
