Technibble, the Australian site for aspiring computer techies, recently released the second version of its popular Computer Repair Utility Kit, a collection of 57 hand picked tools to help you diagnose and repair your Windows machine.

Most of the applications don't require installation and the kit can be run directly from your thumb drive.

There are many situations where a file has been deleted (typically by an overnight log-cleaning process), yet the inode is still held open by a process reading from, or writing to, it. Recovery of such a file is simple, regardless of whether it is on ext2, ext3, reiserfs or any other filesystem. When a file is deleted in linux, it is simply 'unlinked'. The inode, which contains the file's data, is not deleted until all processes have finished with it. This is why processes can carry on writing to deleted files. (Incidentally, this is why linux can be upgraded without requiring a reboot. Programmes, which have shared libraries open, carry on using the old versions of shared libraries until they finish.)

Puppet, the configuration management solution. The Puppet framework provides a means to describe IT infrastructure as policy, execute that policy to build services then audit and enforce ongoing changes to the policy. Puppet helps accomplish the goal of a hands-off, automated infrastructure.  The benefits of automated infrastructure go beyond policy-enforced consistency and auditing.  The impact of hardware failure and other disaster scenarios can be mitigated, as services can be quickly restored by Puppet. In conjunction with virtualizaton, the ability to reliably create new systems running consistent services can be leveraged to create autoscaling applications as well as test systems identical to production environments.

Tips on displaying a downtime message during system maintenance

With multi-core processors sitting idle most of the time and workloads always increasing, it's important to have easy ways to make the CPUs earn their money's worth. My colleague Georgios Gousios told me today how the Unix xargs command can help in this regard. The GNU xargs command that comes with Linux and the one distributed with FreeBSD support a -P option through which one can specify the number of jobs to run in parallel. Using this flag (perhaps in conjunction with -n to limit the number of arguments passed to the executing program), makes it easy to fire commands in parallel in a controlled fashion.

The xargs -P flag can also be useful for parellelizing commands that depend on a large number of high-latency systems. Only a week ago I spent hours to write a script that would resolve IP addresses into host names in parallel. (Yes, I know the logresolve.pl that comes with the Apache web server distribution, and the speedup it provides leaves a lot to be desired.) Had I known the -P xargs option, I would have finished my task in minutes.

Service Wrapper,可以用于包装bat成为一个Windows Service

YAJSW is a java centric implementation of the java service wrapper by tanuki (JSW). It aims at being mostly configuration compliant with the original. It should therefore be easy to switch from JSW to YAJSW. JSW is a wonderful software I have been using for some time in production. So why yet another framework ? The main reason is that I need a better integration within my java job scheduling framework (rzomx) As of the next version the license of JSW will change making it impossible for me to use it in rzomx I may need win64 support, which is currently not available or not free for JSW.

System Administrator Cheat Sheet

I wanted a simple command-line tool to be able to grab real-time stats from memcache (memcached, I know, I know), and output it in a view something like top. I couldn't find anything like it, so I wrote one myself in perl. When writing it, I tried to keep it simple, portable, and lightweight. (No memcached perl modules required! I tried to keep it to modules I thought would be preinstalled on almost any modern system. It's also fairly polite - non-critical modules get checked, and if they aren't installed, the functionality is disabled without spewing errors or dying.) I realize it's not written well. But, hey, at least it exists, right? Until the day I released it, there wasn't any comparable tool like it for memcached. It gives you the basic stats, and not too much else. (You can specify thresholds, for instance, and it'll change color to red if you exceed the thresholds. You can also choose the refresh/ sleep time, and whether to show immediate (per second) stats, or lifetime stats.

Avoid piping a grep to wc -l in order to count the number of lines of output. The -c option to grep gives a count of lines that match the specified pattern and is generally faster than a pipe to wc, as in the following example:

Application Monitor is a program that constantly checks the processes previously chosen by the user, and when it detects that one of those processes has stopped working it will start it again. With Application Monitor you will always be sure that your important processes are running. AppMonitor has been developed keeping in mind all those admin and power users who use programs that must always been running (such as webserver, database, mailserver, p2p) and that don't have a built-in restart function.

adding elb to amazon servers

load balancing

You can load balance your Mysql cluster – however ELB is outside Amazon’s firewall and isn’t integrated with it. This means that to load balance Mysql you need to open it up to the world and rely on strong credentials to keep your data secure, rather than firewall rules.

We’ve been using the new Amazon Load Balancers (ELB) for Socialmod, and since there’s not much information out there on the subject, I thought a blog post would be in order.

Today we’re announcing the availability of the Web-based AWS Management Console, which in this first release provides management of your Amazon EC2 environment via a point-and-click interface. A number of management tools already exist: for example a popular Firefox extension known as Elasticfox; however as you read more of this post I believe you’ll agree that the new console is compelling--especially when it’s time to log in as a new AWS developer.

fsniper lets you monitor specified directories and execute scripts on any new files that are created in them. Because fsniper uses inotify to monitor its directories, the actions you define are executed as soon as filesystem changes happen. This makes fsniper both more immediate than an hourly cron job and more efficient.

# Secure and enhance performance to your Terminal Server and workstations by preventing execution of chosen applications. # Prevent access to any application by executable filename. # Freeware!

Hay algunos programas que, por más que queramos, no podemos desinstalar (¿alguien dijo Internet Explorer en el fondo?). Sin embargo, podemos hacer todo lo posible por ignorar su existencia. Una de estas medidas es bloquear su ejecución, así no se nos abren accidentalmente, ni por asociación con un tipo de archivo en especial. Para hacerlo de forma fácil, contamos con programas como Application Locker, una aplicación gratuita para Windows. El programa cuenta con una lista pre-determinada de programas a bloquear (por eso tal vez vean algunos que no tienen instalados), pero también pueden agregar sus propios programas. Además de evitar que corran los que no quieren, pueden usar esta herramienta para, por ejemplo, evitar que los niños les usen Firefox o el MSN, o mantenerlos fuera del alcance durante las horas de trabajo (un poco de ayuda a la auto disciplina).

Linux has a wealth of utilities to help you monitor what your system is up to. You can run commands, use the proc file system and get the exact state of your system. All this information is of little use if you cannot display it efficiently. You would need a system monitor right? Well let’s take a look at one of my favorite Linux system monitor apps on my system, a system monitor unmatched and unsurpassed by any other when it comes to customization and features. It’s called Conky. Conky can display the stats and information on your desktop or within another window, but trust me, you would want to display it on your desktop! Here are some screenshots of Conky displaying information to give you an idea of what can be achieved with this app.

Using Amazon EC2 Metadata as a Simple DNS

I use the amazon metadata for creating /etc/hosts and do this on a cron schedule. This does everything I need. Instead of fancy DynDNS tricks or having to run and manage an internal DNS server I just have a ruby script that looks at the metadata ec2 to build /etc/hosts. It's easy. To set it up yourself and try it all you need are 3 easy steps. Step 1- Start each of your instances with unique named key that matches what you want their internal hostname to be. Such as "onion" or "potato" or whatever you want to call them. Step 2- Make sure you have ruby, rubygems and amazon-ec2 (rubygem) installed. Then create a ruby script in /usr/local/sbin/hosts that has the following:

Network latency and bandwidth are the two metrics most likely to be of interest when you benchmark a network. Even though most service and product advertising focuses on bandwidth, at times the latency can be a more important metric. Here's a look at three projects that include tools to test your network performance: nepim "network pipemeter," LMbench, and nuttcp.

Stashboard is a status dashboard for APIs and software services. It's similar to the Amazon AWS Status Page or the Google Apps Status Page. Stashboard was originally written by Twilio to provide status information on its Voice and SMS APIs. Stashboard is designed to provide a generic status dashboard for any hosted service or API. The code can be downloaded, customized, and run on any Google App Engine account.
