With FujiNet, I can literally - in BASIC even - open a connection to an HTTP server and pull down data, and just plop it into screen memory.

Somewhat recently, I bought a generic serial adapter for the Atari, and a Lantronix UDS device (ethernet -> serial), but didn't have time to toy with it, and it was all very clunky. I never got around to it, and frankly didn't have much way to get my Atari 'online' (dial-up modem) after college, once things switched from POTS dial-up to fancy things like ISDN and DSL. Using this, a few fun little toys were developed for FujiNet-equipped Ataris, including a (admittedly grim) COVID infection tracker, a 2020 US election results tracker, and a very nice weather forecast app.īack when I was in college, in the mid 1990s (and yes, still using my Atari), I thought it'd be cool to offload a lot of the HTML parsing complexity, and graphics conversion and scaling (GIF or JPEG -> something the Atari can view easily) to the Unix workstation at my school. One of the 'new' device types is a fairly all-encompassing networking device, which is a lot easier to work with than the 1980s-era serial/modem device, and among the protocols it supports is HTTP. These Ataris, some dating back to 1979, don't know or care what's connected on the other end, 'it just works'. Thanks to the way the Ataris were originally designed, between a daisy-chain-able serial I/O bus, and a device abstraction layer in the OS, it was relatively easy to get FujiNet to act as: a modem, floppy disk drives (both local microSD card storage, and over the Internet), printers, and more. It's original goal was to provide WiFi access to an Atari, by offloading all of the hard work to an embedded Arduino microcontroller. One such gadget for the Atari, which is under development, is a kind of swiss-army-knife called 'FujiNet'. There's a (growing!) retro hobbiest community out there, and these days it's become extremely easy (and inexpensive) to create hardware gadgets for these old computers. I grew up with an Atari 8-bit computer that I received as kid back in the early 1980s, and which I still love and use to this day. Nemiroff suggested I post about here on this forum, so here I am.

STEP 1: Download the latest fsimage copy. Lets now read and analyse the fsimage using this OIV tool.

The Offline Image Viewer does not require a Hadoop cluster to be running it is entirely offline in its operation.

If the tool is not able to process an image file, it will exit cleanly. The tool is able to process very large image files relatively quickly, converting them to one of several output formats. The Offline Image Viewer is a tool used to dump the contents of hdfs fsimage files to human-readable formats in order to allow offline analysis and examination of an Hadoop cluster’s namespace. You can perform NameSpace Analysis, find out health of your fsimage, and even explore the interesting usage patterns. At times, it is very important to read the clear text version of the fsimage which holds the meta data of the file system. Hadoop fsimage is an “Image” file and its contents cannot be read easily using normal unix file system tools like cat, more etc. Analyse Hadoop fsimage using the Offline Image Viewer (OIV) Tool
