  • Charted – Charted is a tool for automatically visualizing data, created by the Product Science team at Medium. Give it the link to a data file and Charted returns a beautiful, shareable chart of the data. We built Charted with a few core principles in mind: Charted does not store any data. It only fetches and visualizes what the link provides. It also refetches the data every 30 minutes, so the chart is always up-to-date. Charted does not transform or manipulate data. It displays only and exactly what it receives. Any necessary calculations or adjustments must already be reflected in the data. Charted is not a formatting tool. It is deliberately sparse in features. Charted focuses on getting from the data to the visualization with the fewest decisions possible. As a result, we simplified Charted to just a few options. Here’s a walk-through of those options. [ via ]
  • Simple Amazon Glacier Uploader – Amazon Glacier is a long-term persistent file-storage system for cold data storage. As a GUI wrapper for the Glacier command line tools, The Simple Amazon Glacier Uploader aims to be an upload and download solution that is as durable as your data. SAGU is a single .jar file Glacier interface written in Java for cross-platform accessibility. The use of Java assures that you will have access to your files regardless of your operating system when it is time to retrieve your data.
  • Snapper, The ultimate Snapshot Tool for Linux – Snapper is a tool for Linux filesystem snapshot management. Apart from the obvious creation and deletion of snapshots, it can compare snapshots and revert differences between snapshots. In simple terms, this allows root and non-root users to view older versions of files and revert changes. The features include: Manually create snapshots Automatically create snapshots, e.g. with YaST and zypp Automatically create timeline of snapshots Show and revert changes between snapshots Works with btrfs, ext4 and thin-provisioned LVM volumes Supports Access Control Lists and Extended Attributes Automatic cleanup of old snapshots Command line interface D-Bus interface PAM module to create snapshots during login and logout

  • CloudInit – Community Help Wiki – cloud-init is the Ubuntu package that handles early initialization of a cloud instance. It is installed in the Ubuntu Cloud Images and also in the official Ubuntu images available on EC2. Some of the things it configures are: setting a default locale setting hostname generate ssh private keys adding ssh keys to user's .ssh/authorized_keys so they can log in setting up ephemeral mount points cloud-init's behavior can be configured via user-data. User-data can be given by the user at instance launch time. This is done via the –user-data or –user-data-file argument to ec2-run-instances
  • Tsunami UDP Protocol – Tsunami UDP Protocol: A fast user-space file transfer protocol that uses TCP control and UDP data for transfer over very high speed long distance networks (≥ 1 Gbps and even 10 GE), designed to provide more throughput than possible with TCP over the same networks. The project is based on original Indiana University 2002 Tsunami source code, but has been significantly improved and extended. As such, large portions of the program today are courtesy by Aalto University Metsähovi Radio Observatory. Includes FTP-like client and server command line applications for normal file transfers. It has additionally been extended for high rate real-time data streaming in eVLBI radio astronomy and geodesy (VSIB, PCEVN DAQ). Licensed under the original IU open source license.

  • Simplify Advanced Shell Scripting With Ruby | AIX | IBM Systems Magazine | System p, System p5, Power System | Ruby, SSH, shell scripting, Bull Freeware, sysadmin, – IBM Systems Magazine – Ruby is just for experienced programmers. right? False! Originating in the mid-1990s, Ruby is a fantastic language, made popular recently by the Web application framework—Ruby on Rails. It’s a massively flexible and easy language to learn. You can find Ruby for AIX in the AIX Toolbox at the Bull Freeware. The script we’ll be creating will do the following:


    * Go through a large list of servers.
    * SSH them and determine whether the server is AIX.
    * If so, it will go through all disks, returning their type.
    * It will do all of this completely in parallel in batch at 25 sub-processes at a time.

  • Recovering a lost partition table with a VMFS volume | vInfrastructure Blog – Vi possono essere diversi motivi che portano alla perdita della tabella delle partizioni o alla sua corruzione. Nel caso di datastore VMFS le possibili cause sono: resignature da un altro sistema (ad esempio il backup server, nel caso funzioni in SAN mode), un errore umano (basta eseguire, su dischi condivisi, da vSphere Client un Datastore / Delete da un ESXi non ancora collegato al vCenter Server), o anche a causa di qualche problema lato storage (mi è capitato proprio questo caso di recente su uno storage entry level)[…]

    (Mi è capitato, ho seguito la kb di vmware e ne sono uscito. Comunque sto sudando ancora adesso…)
