  • How to Securely Save All Your Passwords with Keepass
    the database and a description It s not a bad idea to take a look at the other tabs just to see what options are available and if you might want them For example in the Advanced tab you can limit the number of history items per every password entry in the database which is the number of modifications that it will remember Once you re done with Database Settings click OK to move on 4 Add new password entries and groups Now that you have a secure database file you can start filling it up with passwords you want to keep You can organize your entries in groups for easier navigation Some groups are already pre defined like General Windows Network Internet eMail and Homebanking but you can modify or remove these or add new groups as you wish To add a new group just right click anywhere on the left sidebar and choose Add Group To add a new entry right click on the right side of the window and choose Add Entry or click the new icon which looks like a golden key with a green arrow The Add Entry dialog is pretty straightforward What you ll most often want is to set the title which identifies what the password is for the username and the password you want to save If it is login details for a web site or any other network location you want to save enter the URL in the URL field You can also use the Notes text area field to write down any helpful notes regarding your details You can also explore and consider other options like setting an expiration date for your entry custom icon custom colors tags additional field values to save in string fields and so on 5 Getting your password database online safely If you chose to use the master key in addition to the password your password database is encrypted with strong 256bit encryption That means that even if you were to put it online in a publicly accessible location your passwords would be safe much safer than anything that is only password protected What would not be advisable is to make your key public especially if you haven t set the master password and the key is all that s needed to get in What you could do instead is place your key on one SFTP server and your password database on another Then anyone who would want to break into your password database would first need to find out where the key is and then break through the password of your server and then break the password of your password database file That s three significant obstacles to get through If you don t have an SFTP server you could do this by combining a couple of cloud storage services say Dropbox and Box net When you launch Keepass on your computer you would download the key from a private Dropbox folder to unlock

  • 9 Signs You Should Use Linux on Your Computer
    get online your dependence on Windows is even less significant All of the major web browsers except Microsoft s Internet Explorer work on Linux including Firefox Chrome and Opera All of the major applications for chatting and voice calls are also available like Skype and IM clients for various instant messaging networks Specialized clients for Twitter are also available and are quite nice 5 PC games you play work on Linux or you own a game console It used to be that gaming was a big hangup for Linux but things are improving dramatically in that regard It s not that there weren t good quality games on Linux before but they typically included free games from independent developers and often missed the popular commercial titles that the gaming world is usually buzzing about But today Steam is available on Linux and an increasing number of top notch games are getting ported over Valve the company behind Steam and a number of those popular titles like Half Life Portal Team Fortress DOTA and so on in fact believes that Linux is the future of gaming Nevertheless it s still quite possible that some of your most favorite games aren t yet available and if you re playing on your PC that might be a concern If you are gaming on a console like the PlayStation or Xbox or your favorite games are already on Linux then this is a non issue for you Switching to Linux wont disrupt your gaming experience 6 You re tired of adware and spyware getting onto your system You get most if not all software on Windows by downloading and installing a package from a web site of a software maker or a dedicated software download site like Softpedia or Download com It s a well known fact that these often try to install additional software that you probably don t want or need but which may undesirably change some of your settings run in the background consuming resources and even display advertisements or send information about your usage habits spy on you Sometimes they re quite sneaky about the way they do this too It s not uncommon that the checkbox to install such additional programs is preselected by default and made to be easy to miss if there is a checkbox to begin with This almost never happens on Linux and we say almost just to cover for any rare case that we might not be aware of This author has in fact never seen it Most of the software you install on Linux comes from a central repository maintained by the same company that provides your Linux distribution so all software is packaged and maintained by them You get them all through a program that resembles the Mac App Store In Ubuntu it s called the Ubuntu Software Center 7 You want something different While Windows has introduced plenty of changes in recent releases having changed the look and feel significantly between

  • The Easiest Way to Optimize Your MySQL Database Performance
    MySQL originally an independent company the MySQL community including some of its original developers worried about the direction Oracle will take with it and whether it will preserve its open source licensing This led to the founding of MariaDB by the same developer who founded the original MySQL MariaDB is meant to be a fully API compatible drop in replacement while adding some important enhancement Since then many server administrators switched to MariaDB motivated both by its arguably more trustworthy stewardship and its enhancements MariaDB contains more storange engines a number of additional features and most importantly performance improvements Percona was founded in 2006 by two MySQL support engineers to offer MySQL consulting services They maintain the MySQL Performance Blog that is chok full of very useful insights and benchmarks They offer their own fork of MySQL called the Percona Server which is basically MySQL Community Edition with their own optimizations added and including their XtraDB storage engine Both MariaDB and Percona Server will likely offer greater performance than stock MySQL and both are fully compatible with MySQL so you can easily switch to either Probably the main differences between them is that Percona Server is more focused on improving InnoDB table performance whereas MariaDB makes improvements to both InnoDB and InnoDB tables MariaDB also includes XtraDB storage engine from Percona so it might be the best bet for most people who don t have the needs that specifically match what Percona is focusing on Installing MariaDB is pretty easy Some Linux distributions are even starting to include it by default Otherwise you can use the MariaDB Repositories tool to get all the instructions you need to get it installed Once you have it just restarting your MySQL server will be all you need to start using MariaDB Getting Percona Server is similarly simple Check the Percona Software Repositories page for information and links to how to get the repository added and install Percona Server Alternatively you can go to Percona Downloads click the Download button on the latest version and choose your distribution Then you can download and install each package Use The Percona Configuration Wizard Now that you ve got a speedier version of MySQL you can use The Percona Configuration Wizard to help you create the most optimal configuration It is a great and elegant tool that will ask you some key questions about your server resources workload use cases and so on Based on the information you provide it will generate an optimal my cnf configuration file that you can simply copy to your server besides any custom modifications you might have like directory paths The configuration values it generates are tuned to your specific needs while utilizing the Percona s well acclaimed best practices The configuration file it generates is very elegant and easy to read and will probably be way better than whatever you ended up with after endless customizing and testing of your own configuration It s possible that some of the questions

  • Setting up a Linux Web Development Environment in Windows
    press enter again when it asks for a volume size It will ask to write changes to the disk yet again so just select Yes before pressing enter again Basically this is like installing most Windows applications where you typically just keep pressing next until it s done 10 Eventually it will also ask for proxy information You can probably leave this blank and continue 11 Next it asks whether you want automatic updates Either way would be fine so you can just continue with no automatic updates or if you prefer set it to install security updates automatically 12 Finally it will ask you to select extra software to install to tune the system to your needs This allows you to immediately select some of the features you might want on your development server At the least select OpenSSH server and DNS server The rest are up to you but if you re using the typical LAMP stack when developing Linux Apache MySQL PHP you should probably select LAMP server as well To select navigate to the option with arrow keys and select with the space bar Once done press enter to continue 13 Next steps will depend on what you selected As a web developer you ll probably be familiar with what it will ask you for if you selected the LAMP stack like the password for the MySQL root user if any 14 Finally it will ask to install the bootloader Just press enter to say Yes and once it does it press enter again to finish the installation It will reboot into the new system and let you log in with the username and password you specified earlier If you ve opted to install the LAMP server among the previous steps you now already have Apache MySQL and PHP installed and running They were started automatically at boot and the server is already serving a web page on the VM s IP address Remember when we set up networking for the VM by switching it to the Bridged Adapter mode This allowed the virtual machine to use your network card directly which gave it its own IP address on your local network If you run the ifconfig command on your Ubuntu Server virtual machine now you ll see its IP address in the eth0 section after inet addr It will be something like 192 168 5 14 If you type this IP address in your web browser on Windows you ll see the default Apache page served up confirming that your server is working The default web directory or HTTP directory is at var www html where this index html page resides This may in fact be all that you need to get started developing something or testing sans installing any specific software you might need like ruby python node js or whatever else you typically use in your development We won t cover the installation of any extra packages but a lot of them are available with a simple sudo apt get install package command replacing package with say ruby Connecting with SSH Since we ve selected to install the OpenSSH server during the installation process you ve already got it running and you can already log in to it through the above IP address While you can certainly simply run all the commands directly in your VirtualBox window using an SSH client like Putty gives you some extra flexibility and convenience like more easily running multiple sessions setting up colors and fonts resizing the window as you see fit without scaling and so on So if you d like to connect to your new server via SSH get a client program for Windows like putty or the Secure Shell Chrome app launch it and add your virtual machine s IP address as the host When you connect you can log in with your Ubuntu Server s username and password Setting up Virtual Hosts We ll go a bit further though and just quickly show you how to set up virtual hosts so you can assign different host names acting similarly to domain names to different web directories This can be useful if you d like to work on multiple projects at the same time assigning each their own hostname There is a lot of tutorials on setting up Apache virtual hosts out there so we wont go into much detail First of all we need to create the directories for each virtual host Let s call them nuxi1 and nuxi2 to keep things simple You can pick your own as you please of course Run the following to create them in var www sudo mkdir p var www nuxi1 html sudo mkdir p var www nuxi2 html Change permissions to the current user so you can edit them with the following sudo chown R USER USER var www nuxi1 html sudo chown R USER USER var www nuxi2 html Next we need to edit Apache configuration to add our new virtual hosts Quickest way is to copy the existing 000 default conf file into new ones and edit them sudo cp etc apache2 sites available 000 default conf etc apache2 sites available nuxi1 conf sudo cp etc apache2 sites available 000 default conf etc apache2 sites available nuxi1 conf To open a file for editing you can use nano sudo nano etc apache2 sites available nuxi1 conf Then edit it as follows putting all of this is between tags 1 Change ServerAdmin webmaster localhost by editing the email address to your own For example ServerAdmin admin example 2 Change the DocumentRoot line to look like this DocumentRoot var www nuxi1 html replace nuxi1 with your own virtual host name of choice matching a directory you created previously 3 Add ServerName nuxi1 local also replace name as above The local thing can be anything else but local makes sense as a made up domain extension for local hosts 4 Add ServerAlias www nuxi1 local or

  • Hunting Down Disk Space Hogs on Linux Command Line
    well especially if you don t have ncdu on your system If you simply run du it will start listing file sizes of everything under the current directory in kilobytes Chances are this will be a bazillion files flying across your screen making it pretty difficult to plow through Instead of doing that you can pass some options to make the results far more useful For example this command just gives you the total size of all files in the current directory du csh If you do this in the root directory you get total file size on the file system To get the same for home you just run du csh home c produces the grand total s skips listing all the files and just shows the summary h switches to the human readable format for the values But when you re looking for the specific files and directories taking up the most space it can be daunting to check each directory like this Luckily you can use the following command to list total size of all directories within the current one and sort them by size du ch d 1 sort hr The output will look something like this 39G total 39G 25G home 5 2G root 5 1G var 2 4G usr 2 1G etc 36M lib 9 9M sbin 6 7M bin 1 3M run 544K boot 140K opt 88K dev 24K tmp 16K lost found 12K config 8 0K srv 8 0K media 4 0K mnt 4 0K initrd 0 sys 0 proc As you can see home takes the most space root being second and so on Pretty simple You can then move in to home and do the same there d 1 option is what limits the listing to only the first level of directories in the current directory If you want to list two levels just type d 2 instead and so on The sign is the pipe sign which takes the result of the previous du command and passes it to the command after the pipe AKA piping The sort command takes the output of du ch d 1 and sorts it The meanings of options are h sorts it by number in a human friendly form r reverses the order since the above lists from smallest to biggest by default Leave r out if you actually prefer that A couple of other du commands you might find useful allow you to only list the files that are above a certain size or in a specified range of sizes For example if you want to list only files which are bigger than 100 MB run this du ch t 100m This will list all of the files in on the current path that are bigger than 100 MB in a human readable form along with a grand total c If you want to sort it like the previous command just do the piping the same way du ch t 100m sort

    and font of the terminal pinch to zoom option ability to set the pin code length of the buffer size and so on All in all it is on par with ConnectBot in terms of functionality but has some things ConnectBot and misses a few things ConnectBot does have So which you use will come down to your preferences in terms of needed features and user interface style 3 Server Monitor SerafinSoft This app named like a bunch of others just Server Monitor which is why we include the name of the developer is simple but quite useful for basic server monitoring You can add a server by simply specifying its host name or domain name and IP address and it will ping it to check if it s online Then you can add components to each server supporting TCP and TCP over SSH which allow you to check on specific ports running on a given server Settings allow you to set the polling frequency default being 15 minutes sound and vibrate notifications and whether to start te service automatically or not It will run in the background and notify you if something goes offline It s a pretty simple and effective way to monitor for service downtimes 4 httpmon HTTP Server Monitor The function of httpmon is somewhat similar to that of the Server Monitor above as it can also be used to check on specific hosts and ports but it goes much further than that Besides the server host and port specified under the Request option you can set up a number of conditions for which it should check as well Besides simply checking if the service is online by pinging it you can also add conditions that check for a specific response code response time content of the header and content of the actual content sent over HTTP If a certain condition is not met it can send a push notification alert sound flash or vibrate or send you a text message It will also log all of the requests into a log you can view for full details of each request 5 HostEye If neither of the above suit your needs and preferences another one to try is HostEye a neat looking app that allows you to keep an eye on the uptime of various hosts and ports of running services and notify you if something s gone down It can alert you through a phone call or by sending an email and you can also add a widget on the home screen showing the status of your services The lite version is free with the basic functionality which may be enough for most Pro version adds push notifications and some extra settings You may like HostEye for its ability to notify via email and phone calls its widget and its look feel 6 Monyt Monyt is a bit different from previous apps While it allows you to monitor the online status of your server it
