I don't think this will replace your big screen(s) setup any time soon. That said, think about the mobility of a setup like this. Your psuedo-physical dev environment can move with you. I don't know if that's a good thing or not, but I'm certainly interested to see how it evolves.
It seems a simple key mod bucket_size works to divide a workload based on a numeric key. I imagine this has a different distribution which works better for certain use cases. Anyone have an example of when mod will fail for something like this?
Wireshark is a good tool for inspecting 802.11 frames, but it's still a pain. If you do go down this path, I highly recommend adding a capture filter for your adapters MAC, so you don't get flooded with management frames. Filter string: wlan addr 00:00:00:00:00:00.
The devices need to leverage existing standards like TCP or UDP. Then the battle of IoT protocols happens between MQTT, CoAP, and existing things like HTTP. For the extremely tiny devices with low power budgets, these may be too heavy.. so there needs to be some sort of gateway.
The problem then is the same as the internet of now: There is another layer on top of that which is specific to an application. I hope there is a battle for different standards and the best one wins.
While I understand the concern about tracking peoples presence with phones, I don't feel like this is new. The cellular companies can track location, and it's already happening.
BLE is not ideal for accurate positioning, or RSSI for that matter. That said, it works for proximity, which should be sufficient for many applications.
The interesting take away for me was the notion of "presence", which is something that "must be experienced" in order to understand it, and only comes when certain technical criteria are met.
I think the quote means: "I learned that you should go straight to the person you're upset with rather than go to authorities [in prision]." Are you saying this quote is bullshit when it applies to the world outside prison, or inside prison?
I experienced a strange side effect when experimenting with melatonin: My vision degraded as if I was having a migraine. I experienced tunnel vision and colorful artifacts without the headache. I can't say with 100% certainty that melatonin was the cause, but there was a correlation... and I have not experienced the problem since I stopped taking it.
We can't accurately meter our performance, intelligence, and behavior. We also can't control our environment (not realistically anyways). So, it's anecdotal. I'm excited for sensor networking to get in the body, so we can actually measure the effects of our consumption. Then again... that doesn't measure behavior, or intelligence. It's a hard problem.
As of right now, with WebGL enabled, there is no confirmation of execution... it just happens. One time confirmation of execution per domain per code load might be a good option.
It's really an set of tools for lxc. Create "images", boot them, and have a sandboxed execute environment for some service(s). There are repositories with services pre installed. You can get a service running with a command like:
docker run -h myhost -t repo/redis-image redis-server
That creates a container based on the repo/redis-image image, and runs the command "redis-server" once it boots (less than a second on my machine).
Having the ability to control the height of your desk helps. When your feet get sore, lower the desk and sit. It also helps to keep the leg muscles active with small movement.
This post somehow triggered me to grab "Learn You a Haskell for Great Good" this morning and I have been gorging on it since then. I've had quite a few "holy shit" moments.
Java 7 failed to excite me. Java 8 however, has many features that I can use today. Lot's of stuff from guava, cleaner anonymous classes (lamdas), trait-like interfaces, FluentIterable++ (streams)... it's a good time to be a java developer.
One of the best features of the RPI is integration with other hardware (i2c, SPI, GPIO). It's neat to toggle a motor from a bash prompt. When that goes away, it's just a linux box. It looks like you are having fun though, so I applaud that. Edit: I guess the joke was lost on me.
They are not changing the path of Linux, but the path of graphical UX on Linux. I think it's a good thing. The GUI is simple enough for my grandma to use, yet I can open a terminal and have a very familiar experience. I see no harm here, as they will not diverge from Linux itself.
I like the idea but I am not familiar with dynamic columns in maria. Is it possible to query dynamic columns in a way that map to a column slicing operation in cassandra?
Not automagically, but java has some really good tools for helping. See the http://docs.oracle.com/javase/7/docs/api/java/util/concurren... package. Check the Executors section and you can easily distribute work via threads to all your cores. In fact, vert.x is using netty, which makes heavy use of threads along with async IO. You can do both.
