If you’re using /usr/bin/wget to run your Cronjobs you might notice that every time that cron runs – wget will also creates a log file and will places in your home directory. If you run cron too often (every few minutes) it can add up very quickly and pretty soon you’ll end up with thousands of useless (junk) log files in your home directory. Also your disk space could get consumed especially if you’re on shared hosting or have limited amounts of disk space available. We don’t want anything of that.
Solution is pretty simple actually. All you need to do is add an extra parameter -O /dev/null
So your wget command would look something like this:
/us/bin/wget -O /dev/null http://www.script.com/script.php
This will tell to save output to /dev/null – meaning not to save it at all..
It’s as simple as that. Let me know in comments if this worked out!
htop is an interactive process viewer for Linux, which is a powerful alternative to top utility.
Main features of htop:
– Supports mouse interactions
– Better sorting and selective display
– Color formatted display
– Resource graphs
– Process treeview
– Installing htop
To install htop to Redhat or CentOS Linux easily via the yum package manager. However sometimes it happens that yum repository doesn’t have that package, so the rpmforge package repository must be installed first. To install, retrieve, and install the following RPM for your architecture (32bit or 64bit).
rpm -Uhv rpmforge-release*.rf.i386.rpm
rpm -Uhv rpmforge-release*.rf.x86_64.rpm
Now that the rpmforge repository is installed, you can install the htop package easily via yum.
yum install htop
– Have you ever wondered how to setup your own private Cloud service?
– Is there any (preferably self hosted) alternative to DropBox, Google Drive, SkyDrive… ?
– Services like Dropbox and Google Drive are really good but they can cost you money if you need more space.
– You have tried all the alternatives to Dropbox and Google Drive but you need something different?
– Do you really need all the futures they provide?
– Do you need more features (like syncing calendars, tasks, contacts and music)?
– Do you want to be able to install pre-made or develop your own plugins for your cloud?
– Can we really trust companies like Google or Dropbox them with our data?
– Are you a small company or start-up and you can’t afford a $795/year for Dropbox team service?
– You also need iPhone and Android application so you can access your files on your phone?
– You also want a Windows, Mac or Linux Desktop application and Web access?
– You want to host that could on your company server or inhouse? And you want it on a sub-domain like cloud.yourcompany.com?
– And you want it free or really cheap?
Not a problem! We got you covered with all that!!!
The solution to problems listed (and un-listed) above is really simple. All you need is to install ownCloud on your server/hosting. This software is a PHP/MySQL powered so it will work on just about any Linux server and is released under AGPL license.
In case you have hosting (shared/vps/cloud/dedicated) you can skip this paragraph.
If you don’t have one – you can get it pretty cheap these days and my advice is to go with DigitalOcean. They will provide you with great entry level VPS (512MB of DDR3 RAM, 1 Intel Xeon 2GHz Core, 20GB od SSD hard disk space and 1TB of bandwidth) for just $5. Did I mention it’s SSD powered – so it’s blazing fast! Plus you can deploy your VPS in US or NL and you can add backups for 20% (in this case for $1 extra a month). New VPS is provisioned in 60 seconds and you pay per hour of use (not monthly). So you’re invited to play bit with different linux distributions, geo-locations and sizes etc.. and to fully test it out before you put it in production use.
Detailed installation instructions for Digital Ocean can be found in here and if you need any help in setting it up – feel free to contact me.

There are two ways to install IonCubeLoader on cPanel. The standard way includes recompiling Apache using EasyApache from WHM (or shell) and it takes 10-30 minutes to complete and results in Apache restart in the end.
But there’s also a quick way: just login to SSH and execute this command, wait a minute and that’s it!
/scripts/phpextensionmgr install IonCubeLoader
