UPDATE: PENCIL is an opensource software which is a pretty good alternative as well with a smaller learning curve and is Opensource. I was recently looking for Visio alternatives on Linux and while Dia is good it lacks the oomph of Visio and hence not an easy sell for new and potential Linux converts. Now good news for those open to enter the wonderful world of Linux is that any OS need not have an alternative for it to be usable to you, all it needs is the ability to let you run the software you find useful. So this post isn't about why Linux is better. It is about knowing that there is something better than the software you have got accustomed to. If someone is adamant on continuing with the software they have fallen in love with, there is always WINE / Virtualbox but if you have opened to the idea of new OS but you are taking baby steps software like yEd can help you take a giant leap. yEd is written in Java and can run on Windows, Mac and of-course Linux. Before we move into the steps of how to get it and use it let me bore you little with what are the other alternatives I explored. During my quest I came across two other useful candidates Activiti 5.6, ARIS Express 2.3. What went against these and in favour of yEd? Read on: Ease of installation First on the list is ARIS Express 2.3. Now this requires registration which is my first gripe. I could have lived with that but as claimed on their website the product is meant for Windwos and is reported to be working fine for Linux. What they forgot to mention is on linux using Wine or atleast that is what it did on my set-up. Now am not sure if it has something to do with my installing JRE in wine for using Open Workbench (see last post) or it is because the product works on similar lines as Open Workbench installer but eighther way it does not run natively on Linux and for that reason alone it is unreliable and looses points even to Activiti. For easiest installation, Activiti 5.6 can be added into Eclipse but that results in a bit complicated and not so user friendly user-experience. You will at-least need to have one Activiti project created in eclipse before you can draw using Activiti Diagram. (Check Screenshot) Above might be circumvented by installing standalone Activiti bit that involves configuring ANT and other stuff. While guide is there, it is not very straight forward and considering we want to win new users not scare them, it is best left as untouched topic. Ease of Use - While all the three products yEd, Activiti and ARIS are superior to Visio, in terms of ease of use I think it's yEd which wins hands down even to Visio. The one aspect of this software that won me over was it's ability to auto align the whole flowchart / diagram with just one click and it can do it in several layouts. OK, now that I have covered comparison, let's get down to how we install it on our beloved Linux Mint. It's really very simple. Step 1: Go to this website - http://www.yworks.com/en/products_yed_download.html Step 2: Download yEd for your platform. In our case for Linux Mint the 43 MB sh file in front of Linux. Step 3: a) Go to the folder where it is downloaded, select the yEd-3.7.sh file and right click on it. b) In the right click menu select Properties (last entry). This will open the yEd-3.7.sh properties box. c) On the Properties box, click on Permissions tab. d) Click the checkbox in front of Execute Allow executing file as program. e) Click Close. f) Double click on the yEd-3.7.sh file. It will display a dialogue box with four options Run in terminal, Display, Cancel, Run. Select Run in terminal g) yEd will now install, it may give one small error but it did not affect anything at all so ignore it if you get it. h) Follow the wizard and leave default options. i) Once done, you will have yEd successfully installed and can be found in MENU ALL APPLICATIONS-OTHER. j) Create a shortcut of yEd by dragging yEd from MENU ALL APPLICATIONS-OTHER onto desktop. You may need to make this dragged link executable by right clicking the link and following steps b,c and d. All Done !!! A quick tutorial from yWorks: Find more on http://www.yworks.com/en/products_yed_videos.html Having seen, how nice and easy it is to create the flowchart, let's also see the best feature of the product that is one click alignment.

Visio Alternative on Linux - Business Process Model and Notation Tool

While the majority of settings are covered in my previous post here I found that each time I switched off my printer, it used to change it's IP address and I had to repeat Steps 7 to 16 each time. My printing and scanning needs are pretty limited so I never bothered working out a solution until today and knowing what I now know, it was quite a simple and quick solution I should have done this on the first place. Anyway as they say better late than never. :) So to carry out the magical transformation to your printing experience follow the steps below: On your printer (actual machine not on laptop / computer) go to Settings (Press the button with Wrench and Screwdriver symbol as shown in picture). Using left arrow navigate to Network Settings (Computer and Printer icon) Click OK button. Using down arrow navigate to "General Setup" and click OK button. Printer will show the question "After changing the settings, network may be disconnected. Continue?" and present options Yes and No with No selected (highlighted in Yellow.) Using left arrow move to Yes and press OK. Printer will now show the screen for "Printer Name Setup", do not change anything. Just Click OK to proceed to next screen. Now printer will show screen for TCP/IP screen with two options Auto which is selected by default and highlighted in yellow and Manual. Here using down arrow key select Manual. Click OK button. The screen will show current IP address assigned to printer something like 192.168.1.66. Now I am assuming that you have already followed part 1 of this tutorial so on your laptop open the file epkowa.conf from /etc/sane.d. You can also open this file by typing the following command in terminal gedit /etc/sane.d/epkowa.conf Note down the IP address you entered last time 192.168.1.60 below usb and scsi. (Line 12 on my file.) Now on your printer change IP address to match the one on last step. To do so, first click on left arrow on printer to reach the last digit of displayed IP address and then adjust the number using up or down arrow. Once it is same as that on epkowa.conf file (192.168.1.60 in this example), click OK button. Now continue to click OK button on all remaining screens till you reach Network Settings screen (About 5 times) Press OK one final time and that's it you are done. If you are to now switch off and switch on the printer and test scan it should work without any issues. Hope you find this useful.

Part 2 - Configure Epson S515W on Linux Mint / Ubuntu 10.04

UPDATE While this tutorial will get your printer up and running, you should also follow Part 2 to ensure that it continues to work even after you have restarted your printer. -Ankit Lately I have not done much experiments and hence a stable system. I did not require any changes and all was well and then recently I changed over to Linux Mint which by the way is a UBUNTU derivative, very slick and very cool. Now after this reinstall I was able to get back all my previous installs and everything the usual way but scanning using Epson S515W was not out of the box and below are the steps I followed to get it working: Step 1: Configure Printer Step 2: Test Print a page Step 3 - Install drivers and software for scanner Step 4 - Test Scanner Step 1: Configure Printer This really works quite easily in all Ubuntu installs. Goto System > Administration > Printer Now you can see my printer configured but when you will get this window, you wil only see Print_to_PDF. You should then Click on arrow next to ADD and select Printer. It will open the window below: Again under Network Printer it may not show anything initially but if your printer is on and configured to your wireless router it will identify in a moment or two. If it does not, click on Find Network Printer. Once your printer appears, click on it and then click on "Forward". Step 2: Print a test Page Open the Printer window again from System>Administration>Printer and double click on printer. It should open the following window: Click on "Print Test Page". If it prints the ubuntu test page correctly your printer is configured. Mine was so I will not go more in details of alternative option. If you do want to know more let me know and I will put a post. However if now you will try to scan you will find that scanner either is not identified or if it is it does not complete the scanning and printer gets hanged, so over to next steps then. Step 3 - Install drivers and software for scanner Goto the avasys site that provides downloads and navigate for your model or if you have the same as mine just click on the link below and then goto Downloads and select All In One Printers. On the next page scroll down all the way and select the radio button for your printer. http://avasys.jp/eng/ Now these installs need to happen in a sequence and we don't need all deb files on the next page anyway so I will mention download and install in sequence as it should be done. From the section "Download for Epson Stylus NX510/NX515/SX510W/SX515W/TX550W data package" download the data package iscan-data_1.4.0-1_all.deb. Install this package now. From the section "Download for Epson Stylus NX510/NX515/SX510W/SX515W/TX550W core package" download iscan_2.26.0-3.ltdl7_i386.deb. Install this package now From the section "Download for Epson Stylus NX510/NX515/SX510W/SX515W/TX550W network plugin package" download iscan-network-nt_1.1.0-2_i386.deb Install this package now. Now on your printer(actual machine not on laptop / computer) goto Settings (Press the button with Wrench and Screwdriver symbol as shown in the image Printer Control). Using left arrow navigate to Network Settings (Computer and Printer icon) Click OK button. Using Down Arrow select "Confirm Settings" and click OK button. Press Down Arrow twice and it should show the Printer IP Address. Note it Down. It will be something like 192.168.1.60. Now back on your laptop open terminal and type gksudo nautilus. You will be asked your superuser password. Provide that. It will open the file explorer with admin privileges. Be extremely careful now, you do not want to delete anything in this privilege mode. In the file explorer, click on "File System" and browse to the file path etc>sane.d and open the file named epkowa.conf. (Screenshot below) In the file below usb and scsi add the line net 1865 so for our example this will be net 192.168.1.60 1865. (In gedit it was line 12 for me.) Save and close the file. Close all windows. Step 4 - Test Scanner Now open Menu>All Applications>Graphics>Image Scan! for Linux. This should open the software window. Now click on preview to see that a document preview is produced. If it does you are all set. If not you must check the configuration of epkowa.conf and try again. The preview of my 3.5 year olds drawing from scanner : and the final scan is shown below:
