HVM vs PV is confusing because as Xen improves the performance characteristics of the two modes change. Brenden Gregg covered the differences in quite some detail in a recent blog post [1]. Basically, if you are running a new enough kernel

True, but the m1.small had instance storage as an option. Since there is no m3.small and EBS is out of the question, it looks like I'll be moving my m1.smalls to m3.mediums.

Most of the new instances are HVM only. PV vs HVM has become quite complicated but thankfully we have Brenden Gregg to straighten it out for us[1]. [1]: http://www.brendangregg.com/blog/2014-05-07/what-color-is-yo

The Court has begun to limit the scope of software patents, but has not eliminated them. This ruling is a step in the right direction and the unanimity of the Court should be taken as a positive sign for future cases.

Anandtech suggests that fabless ssd companies are having a harder time competing[1]. In such a light, the strategic long term upside would be more important than the premium paid by SanDisk. [1]: http://www.anandtech.com/sho

Yes I have used the Dreamplug, the Mirabox is a logical upgrade from that. The Mirabox uses a Marvell Armada 370 SOC. When I first got my Mirabox the kernel support wasn't great. But Marvell has been contracting with an embedded Linux

Right, you are paying an extra $945 for them to install a wifi card/antenna and preload a bunch of open source software on it. I'm sure that for some people it is totally worth it, and others would rather do it themselves. I mostl

Looks like the "Pwnie Express PwnPlug R2"[1] is just a Mirabox[2] with an extra wireless card in the Mini PCIe slot and an external antenna. The PwnPlug R2 sells for $1095; the Mirabox sells for $150. [1]: https://www.p

I've evaluated a lot of embedded arm dev boards. The first thing I look at is "Can I run a stock kernel on this board?" If the answer is no, its really a deal breaker. Without a stock kernel you are at the mercy of the vendor

If I were implementing something tracking the rate of exceptions a reasonable thing to measure it against is the total number of requests. In such a system, if each request generated multiple exceptions you would have >100% exception rat

Nope. The conclusion is that it is really easy to benchmark the wrong thing. If you are trying to evaluate AWS vs DO vs Google Compute Engine vs Joyent you better make sure you are actually comparing apples to apples. Your comparison will p

Your example of `foo.go` and `foo_test.go` would actually work the way you want. In go, tests are in the same namespace as the code they are testing so they have access to private members.

If you find strace useful, you should check out sysdig[1]. Sysdig is like strace but uses kernel trace points instead of ptrace so it has a lower probe effect on the running process. [1]: http://www.sysdig.org/

There are lots of applications that require a cryptographically secure random number generator, which math/rand doesn't claim to be.

Regardless of what editor you use, be careful that it isn't leaving copies of your passwords other places on your filesystem. For example vim will save your recent yank registers in ~/.viminfo by default. You can avoid this with v

@bcantrill is the SVP of Engineering at Joyent. I don't want to put words in his mouth, but I'm guessing he would say that Joyent is trustworthy. He would then tell you to use DTrace.

Interesting. I'll have to give that a try. Wayland is supposed actually to fix this but its a little depressing how long we'll have to wait for that.
