The lack of JIT is interesting to me; JIT does give higher performance, but at a memory cost (because JITted code is not shared between processes). I think the 3 sweet-spots are: * JIT (OpenJDK, Android Dalvik) * AOT compilation (Android AR

My guess is that the customer for whom they developed this has crypto-acceleration hardware that is supported by OpenSSL. Also, this is only doing the actual crypto operations, not running the whole SSL protocol. Edit: I guess it's al

The question is whether the slide-deck was self-fulfilling because it came from Sequoia.

To save people a long read, there's nothing particularly surprising in these details. The key is held by the origin; when a computation using the key is needed the origin is asked to perform it over a secure connection. They have impr

I certainly take your point; that would be awesome. And thanks for the iOS information! It was more confused by the original article though; he seemed to be suggesting that you would click on a particular UI component first: Want to open

This article is not technically accurate. Most importantly, the distinction between virtual-memory stacks and copying stacks is incorrect: if the process uses more stack space than it has physical RAM, it is going to (try to) swap, whether

Presumably you just want to replace the _Oracle_ JVM? Does OpenJDK meet your needs? How about Dalvik / ART or RoboVM? I'd love to hear what you're trying to achieve here ... I have often bemoaned the JVM, but have also foun

This would be interesting if they "put their money where their mouth is", by selling insurance. 0.01% chance of reversal? Then charge me $0.01 for a $100 transaction, pay me $100 if it is not confirmed. Or charge me $0.05 and en

I love that CoreOS uses lean-startup style voting for biz-dev type decisions (e.g. which clouds should we run on next?); yet can also produce new technologies like etcd, fleet & Rudder through "vision" - knowing which pieces a

Interesting - I definitely accept the value-of-time argument (that's why I just use flat-rate, rather than going to the effort of weighing the package). Sounds like I should try Shyp next time!

Interesting - I've always used USPS Flat-Rate Priority Mail: 2 or 3 day service; free boxes; no need to weigh; free pickup at my door. About $5 for small boxes; $10 for medium boxes; $15 for larger boxes. I still hope that the USPS wo

Can anyone tell me why speeding tickets aren't enforced with video cameras (like red-light tickets are)? It would seem to be much more accurate, much easier to enforce, and much harder to dispute. Irrespective of the rights or wrongs

Looks interesting, but it's difficult to understand why it is faster (i.e. the design decisions you made). From poking around, I can see that you have specialized each collection for the primitive types, to avoid boxing/unboxing.

I'd recommend just using Google GSON instead; it gives you a low-level API comparable to json.org (though much better internally IMHO), as well as a powerful annotation/reflection driven API.

I'm not sure S3 has changed nearly as much as the rest of AWS, which is probably why it is so stable. Regardless, the point is that outages can happen to S3 as well, and have; just because it hasn't happened for a few years doesn

by justinsb 12y ago
I wasn't saying it was, merely reporting the facts! S3 targets four nines uptime; which is really good but not infallible. For most apps though, I think it's reasonable to accept that if S3 is offline, the app is offline also.

S3 went down in 2008 for a few hours. Lots of coverage at the time. e.g. http://techcrunch.com/2008/02/15/amazon-web-services-goes-do...

Does this just look for library versions with known vulnerabilities, or does it do source code analysis?

Sorry! I also think it's a bad rule, because as a society we should be rewarding you for driving a fuel-efficient car, rather than effectively giving higher tax breaks per mile to those that drive less efficient cars.

Is this an old presentation? Doesn't Go now start with 8KB stacks per goroutine, which is the same as OS level threads (which physically allocate 8KB from a larger virtual mapping)? I thought the benefits of goroutines were now about

If you're hoping to see patent reform, this dispute seems to be the wrong one to focus on. This strikes me as more of a genuine argument, and not a flagrant abuse of the system that would likely lead to change: * AGIS seems to be a ge

That is encouraging though: this doesn't get NIH grants, so it hasn't been pursued academically. Thus a group that is able to pursue it, because they got funding from an alternate source (Kickstarter), would be more likely to ach

by justinsb 12y ago
This applies to both goroutines & native threads, right? I guess with both you could periodically re-shrink the stack / release memory back to the OS, but I don't think either go or any native threading system I'm aware
327.
by justinsb 12y ago
I've been wondering about this as well. Goroutines start with an 8KB stack size now; native threads seem to use an 8MB _virtual_ stack size of which often only one or two pages (of 4KB) will be used. So is the primary remaining advan

I'm certainly not saying discriminatory pricing is entirely fair :-) But the article's premise is that costs haven't come down, and that simply isn't true. (Admittedly the reasons likely have more to do with T-Mobile&#

Without getting into the whole rabbit-hole of monopolies/government good vs evil... Do you see any realistic alternative to an auction allocation system for mobile frequencies?

by justinsb 12y ago
Indeed. Prices _have_ come way down, but the carriers are engaging in price discrimination (quite rationally). You don't get the new prices automatically, you have to switch carriers/plans or persuade your current carrier that y
