  • ipfs/ipfs · GitHub – IPFS (the InterPlanetary File System) is a new hypermedia distribution protocol, addressed by content and identities. IPFS enables the creation of completely distributed applications. It aims to make the web faster, safer, and more open. IPFS is a distributed file system that seeks to connect all computing devices with the same system of files. In some ways, this is similar to the original aims of the Web, but IPFS is actually more similar to a single bittorrent swarm exchanging git objects. You can read more about its origins in the paper IPFS – Content Addressed, Versioned, P2P File System. IPFS is becoming a new major subsystem of the internet. If built right, it could complement or replace HTTP. It could complement or replace even more. It sounds crazy. It is crazy. [ via http://blog.quintarelli.it/2015/12/ipfs-davvero-figo.html ]

  • FreshRSS/FreshRSS · GitHub – FreshRSS is a self-hosted RSS feed agregator like Leed or Kriss Feed. It is at the same time light-weight, easy to work with, powerful and customizable. It is a multi-user application with an anonymous reading mode. Official website: http://freshrss.org Light server running Linux or Windows, it even works on Raspberry Pi with response time under a second (tested with 150 feeds, 22k articles, or 32Mo of compressed data) * A web server: Apache2 (recommanded), nginx, lighttpd (not tested on others) * PHP 5.2.1+ (PHP 5.3.7+ recommanded) * Required extensions: PDO_MySQL or PDO_SQLite, cURL, GMP (only for API access on platforms under 64 bits) * Recommanded extensions : JSON, mbstring, zlib, Zip * MySQL 5.0.3+ (recommanded) ou SQLite 3.7.4+ * A recent browser like Firefox 4+, Chrome, Opera, Safari, Internet Explorer 9+ * Works on mobile
  • PressLabs/gitfs · GitHub – gitfs is a FUSE file system that fully integrates with git. You can mount a remote repository's branch locally, and any subsequent changes made to the files will be automatically committed to the remote.
  • Redirect HTTPS to HTTP (or vice-versa) | WP-Mix – Most server configurations should redirect by default when HTTPS isn’t configured, but I’ve seen many cases where pages requested via https return the default server page, a 404 error, or duplicate content. So check first and then proceed accordingly.

  • S3QL – nikratio – S3QL is a file system that stores all its data online using storage services like Google Storage, Amazon S3, or OpenStack. S3QL effectively provides a hard disk of dynamic, infinite capacity that can be accessed from any computer with internet access running Linux, FreeBSD or OS-X. S3QL is a standard conforming, full featured UNIX file system that is conceptually indistinguishable from any local file system. Furthermore, S3QL has additional features like compression, encryption, data de-duplication, immutable trees and snapshotting which make it especially suitable for online backup and archival. S3QL is designed to favor simplicity and elegance over performance and feature-creep. Care has been taken to make the source code as readable and serviceable as possible. Solid error detection and error handling have been included from the very first line, and S3QL comes with extensive automated test cases for all its components.
  • Using Foreman, an Opensource Frontend for Puppet – – The recent vulnerability in bash, got me running to update bash. It’s easy when you have maybe one or two Linux servers, but what do you do if you have 100’s or even thousands or servers? You need to use a server configuration and management tool like puppet. However, instead of using the command line, I wanted a GUI tool where I could select the servers or server group and select an action. That is where I found Foreman, A opensource tool which not only handles configuration of your servers but also does provisioning. Foreman is easy to install, opensource, has community based support and a good deal of documentation.
  • Power Up Your Authentication with Open LDAP and Puppet | DataCentred – When you’re busy automating your infrastructure, a recurring theme that causes questions and problems is this: how do you reliably integrate your data (which changes all the time) into your configuration? As a hosting company, we find ourselves needing to tend to an ever-increasing number of devices: servers, switches, routers, hypervisors, you name it. A staple mechanism for centralised authentication is the use of an LDAP server to manage a directory of users and groups and to perform authentication of credentials and privileges on behalf of other devices on the network.
  • Enterprise/Authentication/KerberosServices – Ubuntu Wiki – This article explains a little bit about the Kerberos protocol and how it can be used in Ubuntu. It's not a thorough manual, use more authoritative sources to get more accurate information and update if you see obvious mistakes.

  • sebsauvage/rss-bridge – The RSS feed for websites missing it
  • debsecan – The debsecan program evaluates the security status of a host running the Debian operation system. It reports missing security updates and known vulnerabilities in the programs which are installed on the host. debsecan accesses the dpkg database and obtains a list of installed packages and their versions. This list is then evaluated against a feed of vulnerability information which ultimately comes from a database maintained by Debian's Testing Security Team . Various output formats are supported, including incremental reporting via email. Beginning with version 0.2, debsecan includes a script called debsecan-create-cron, which allows you to create a cron job which periodically sends you mail (once per day) when the security status of the system changes.
  • Barriers, Caches, Filesystems | monolight – With the recent proliferation of ext4 as the new “default” Linux filesystem there’s been much talk of write barrier support. The flurry of post-2.6.18 barrier related development in most storage subsystems has left some novice users and administrators perplexed. I hope I can clear it up a bit with this primer/refresher.
  • SMTP, testing via Telnet – FreeBSDwiki – When troubleshooting problems with SMTP service – your own, or others – it is frequently very helpful to be able to "speak" to the SMTP server directly, rather than going through a mail client which won't necessarily tell you exactly what the SMTP server is saying. You can easily do this with the telnet client. Note that many ISPs do not allow outbound connections on port 25 to any SMTP server but their own – if you get timeouts when trying to connect to port 25, you should try port 587, which is the standard ESMTP port. (Port 587 connections normally require SMTP AUTH, which is covered below.)

  • Passwordless – A node.js/express module for token-based logins – Token-based authentication middleware for Express & Node.js […] Passwords are broken. Inspired by Justin Balthrop's article Passwords are Obsolete token-based one-time password (OTPW) authentication is faster to deploy, better for your users, and more secure. […]
  • Mounty for NTFS – A tiny tool to re-mount write-protected NTFS volumes under Mac OS X Mavericks in read-write mode.
  • tinc wiki – tinc is a Virtual Private Network (VPN) daemon that uses tunnelling and encryption to create a secure private network between hosts on the Internet. tinc is Free Software and licensed under the GNU General Public License version 2 or later. Because the VPN appears to the IP level network code as a normal network device, there is no need to adapt any existing software. This allows VPN sites to share information with each other over the Internet without exposing any information to others.
  • AIXchange: More Resources for AIX Newbies – As I've noted previously, there are more newcomers to the AIX platform than you might imagine. A company may acquire an AIX system through a merger or replace an old Solaris or HP-UX box with a current IBM Power Systems model. As a result, one of their IT pros suddenly becomes the AIX guy. So, now what? How does an AIX newbie get up to speed with virtualization and AIX?

  • jordansissel/fpm – Effing package management! Build packages for multiple platforms (deb, rpm, etc) with great ease and sanity.
  • Linux incrond inotify: Monitor Directories For Changes And Take Action – I want to copy (rsync to remote server) a directory tree whenever file uploaded or deleted in /var/www/html/upload/ directory under Linux operating systems for backup purpose and/or load balancing purpose without getting into complex file sharing setup such as NFS or GFS iscsi storage. How do I monitor /var/www/html/upload/ and its subdirectory for new files and executes rsync command to make copy back to www2.example.com:/var/www/html/upload/? inotify is an inode-based filesystem notification technology. It provides possibility to simply monitor various events on files in filesystems. It is a very much powerful replacement of (obsolete) dnotify. inotify brings a comfortable way how to manage files used in your applications. The incrond (inotify cron daemon) is a daemon which monitors filesystem events (such as add a new file, delete a file and so on) and executes commands or shell scripts. It’s use is generally similar to cron.
  • Use incron to Trigger Action when File Changes – There are some situations, when you need to start an action or run a command when a given file has changed in your file system. The real life example I have is as follows: I have a git repository, from where I manage this blog, I have a remote branch of it on the same server, from where Nginx serves this pages. I also have another remote branch in my Macbook Pro (With the correspondent Time Machine backup). But, I’m a paranoid guy, so I just want more backups. I decided I wanted to backup all my blog files to my Dropbox account.

  • FhGFS Wiki: Tips and Recommendations for Storage Server Tuning – Here are some tips and recommendations on how to improve the performance of your storage servers. As usual, the optimal settings depend on your particular hardware and usage scenarios, so you should use these settings only as a starting point for your tuning efforts.
  • Linux NAS optimizations ← BAFM – […] Well, I recently had to flatten my archive NAS (well only the OS part … *wheeeh*). Since I didn’t have the chance to backup the old settings I had to do everything from scratch … And this time I decided, I wasn’t doing a script but rather the proper way. I spent a while reading through the Internetz about the various settings until I stumbled upon a Frauenhofer Wiki entry. From there I ended up writing those udev-rules and the sysctl configs…[…]

  • ZPanel | The free web hosting panel – ZPanel is an easy to use, enterprise class web hosting control panel with support for unlimited resellers. From the largest business to SOHO or development environments, ZPanel can support your needs.
  • Bucky — Performance Measurement of Your App’s Actual Users – Bucky is a client and server for sending performance data from the client into statsd+graphite, OpenTSDB, or any other stats aggregator of your choice. It can automatically measure how long your pages take to load, how long AJAX requests take and how long various functions take to run. Most importantly, it's taking the measurements on actual page loads, so the data has the potential to be much more valuable than in vitro measurements. If you already use statsd or OpenTSDB, you can get started in just a few minutes. If you're not collecting stats, you should start! What gets measured gets managed.
  • Linux on 4 KB sector disks: Practical advice – Advanced Format disks use 4,096-byte sectors rather than the more common 512-byte sectors. This change is masked by firmware that breaks the 4,096-byte physical sectors into 512-byte logical sectors for the benefit of the operating system, but the use of larger physical sectors has implications for disk layout and system performance. This article examines these implications, including benchmark tests illustrating the likely real-world effects on some common Linux file systems. As Advanced Format disks have become the norm, understanding how to cope with these disks is a vital skill for anyone who wants to avoid serious performance penalties associated with suboptimal configuration.
  • WPScan by the WPScan Team – WPScan is a black box WordPress vulnerability scanner.
  • SiteSucker for OS X – SiteSucker is a Macintosh application that automatically downloads Web sites from the Internet. It does this by asynchronously copying the site's Web pages, images, backgrounds, movies, and other files to your local hard drive, duplicating the site's directory structure. Just enter a URL (Uniform Resource Locator), press return, and SiteSucker can download an entire Web site. [ via http://onethingwell.org/post/79174700058/sitesucker ]

  • Observium – Observium is an autodiscovering SNMP based network monitoring platform written in PHP which includes support for a wide range of network hardware and operating systems including Cisco, Windows, Linux, HP, Dell, FreeBSD, Juniper, Brocade, Netscaler, NetApp and many more. Observium has grown out of a lack of network monitoring platforms which are both simple to manage and pleasant to use. It is intended to provide a navigable interface to the health and performance of your network. Its design goals include collecting as much historical data about devices as possible, using as much auto-discovery as possible with little or no manual intervention, and having a very intuitive interface. Observium is not intended to replace an up/down alerting system like Icinga or Nagios, but rather to complement it with an easy to manage, intuitive representation of historical and current performance statistics, configuration visualisation and syslog capture.

  • Secure encrypted backup using duplicity for Linux and Mac – I have been looking for a replacement alternative to Dropbox which I use on my Mac mainly for backups (I rarely use the sharing). The requirements were secure encrypted backup (where I control the keys) and “intelligence” so incremental backups could be performed i.e. not copying everything every time[…]
  • Duplicati – Duplicati is a free backup client that securely stores encrypted, incremental, compressed backups on cloud storage services and remote file servers. It works with Amazon S3, Windows Live SkyDrive, Google Drive (Google Docs), Rackspace Cloud Files or WebDAV, SSH, FTP (and many more).   Duplicati has built-in AES-256 encryption and backups can be signed using GNU Privacy Guard. A built-in scheduler makes sure that backups are always up-to-date. Last but not least, Duplicati provides various options and tweaks like filters, deletion rules, transfer and bandwidth options to run backups for specific purposes. Duplicati is licensed under LGPL and available for Windows and Linux (.NET 2.0+ or Mono required). The Duplicati project was inspired by duplicity. Duplicati and duplicity are similar but not compatible. Duplicati is available in English, Spanish, French, German, Danish, Portugese, Italian, and Chinese.
