stkim1··on Image Map View for Android, like HTML <area> tag
An image view to select a complex polygon map out of many. Extremely useful for handling touches on, for example, Europe map.

Ah, actually, the author's github repository has notebook, data, and additional tutorials. It's just that he did not link them in README.md. For example, you can see "Beginner MNIST" here ( https://github.com/Andrewnetwork/WorkshopScipy/blob/master/N... ) Since every collected project is periodically updated, the links in README.md might work sometime later.

I'm usually very careful when selecting a project, and his project gave me a hesitant moment. But, I thought the amount of material gone into building the project would outweigh inconvenience. I think I was short-sighted there. I'll make a note on this, and try to make clear communication with author in the future.

The examples are there to provide interesting implementations, tutorials, and/or articles as easy entries. I'd say some of them might look little dull to experienced veterans.

Nonetheless, they are valuable for those who seek to indulge into the fields. Hope you can look at them in that angle.

In terms of performance per cost, the cluster isn't on par with x86 system. Probably, not even close. Nonetheless, the network cost is real, and you get to have a first hand experience of how your algorithm performs.

Matthew Saunders also designed a very nice cluster stack.

stkim1··on Raspberry Pi 2 Cluster Case, Part 2
Thank you very much! I'll look into that!

It only serves two fronts; education and development. Education-wise, you need something dirt-cheap to play with. For developer, you need some intermediate stage to deploy your work to test before going after a big cluster.

David Guill is another deadly serious RPI cluster builder. I don't know what he's running, but I can only admire what he had done.

You are da man. This is really cool! I can only imagine how much you've been through!
stkim1··on Raspberry Pi 2 Cluster Case, Part 2
I'm looking into that. When you have a lot of memory, it's in fact more convenient in a way that you can carry the entire cluster in your laptop. lol

Thank you!

PXE boot is something I thought about, but I don't know if it is possible on RPI. Do you have any link where I can just go read up about that?
stkim1··on Raspberry Pi 2 Cluster Case, Part 2
Yes I do. Since Apache Spark is chewing up memory like nothing, I cannot spare any portion of 1G mem for something else. This could lead to a shorter lifespan of SD cards though.

I've never imagined the RPI cluster to be taken seriously for production purpose. It only serves two purposes; education and developmental staging. For those two, you have a real hardware cluster that serves you superbly showing every nature you can experience with big-ass datacenter cluster.
stkim1··on Raspberry Pi 2 Cluster Case, Part 2
In fact, storage is a big issue. RPI tends to destroy SD card in a way that a cluster like mine isn't exactly safe unless you put high-grade SD card and very reliable power source. Those contribute somewhat higher operation cost which violate the purpose of these single board computer.
stkim1··on Ask HN: I need to transfer 10TB of Data across Pacific
I really appreciate your warm gesture. I wish my neighbors are just as kind as you are, sir.
stkim1··on Ask HN: I need to transfer 10TB of Data across Pacific
See? this is funny. Some says this is the age of data. 10T is just a tiny amount of bits for some entities, and I cannot reliably transmit that much across pacific other than shipping actual HDD. :(

Thank you for the comic.

I'm trying to finish up a logger app for iPad. Based on NSLogger (https://github.com/fpillet/NSLogger), my goal is to build an app that could be useful out in the field when you're to debug or monitor how your app is behaving.
