  • 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.

  • tune apache peformance using mpm prefork module – There could be many reasons why your website performance is poor, one of them can possibly be that Apache is not coping with the load. Below you’ll find ready to consume configuration to make Apache performance better using the Apache MPM prefork module.
  • check-httpd-limits – Check Apache Httpd MPM Config Limits – Google Project Hosting – check_httpd_limits.pl compares the size of running Apache httpd processes, the configured prefork / worker / event MPM limits, and the server's available memory. The script exits with a warning (or error message) if the configured limits exceed the server's available memory. The script does not use any 3rd-party perl modules, unless the –save/days/max command-line options are used, in which case you will need to have the DBD::SQLite module installed. It should work on any UNIX server that provides /proc/meminfo, /proc/*/exe, /proc/*/stat, and /proc/*/statm files. You will probably have to run the script as root for it to read the /proc/*/exe symbolic links.

  • 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.
  • nikratio / S3QL — Bitbucket – S3QL is a file system that stores all its data online using storage services like Google Storage, Amazon S3, or OpenStack.

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.
  • 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).

  • 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.

  • Centos yum 404 repository errors | Natural Order Development – […] Basically yum ran through every single mirror and got nothing but 404 errors. I thought something might have gotten broken with yum or maybe the entire Internet changed overnight to a new repository layout (not likely but it has happened before). Well a simple Google for yum 404 led to some message threads that basically said yum's caches were out of data […]
  • Avoiding reboot: Resetting USB on a Linux machine – Every now and then, some USB device misbehaves badly enough to knock out the entire interface, to the extent that the system doesn’t detect any new USB devices. Or work so well with the existing ones, for that matter. The solution for me until now was to reboot the computer. But hey, I don’t like rebooting Linux!
