VIM Project (VI Improvied IDE Editor extension to facilitate web development with vi enhanced editor

Wednesday, August 25th, 2010

I use VIM as an editor of choice for many years already.
Yet it's until recently I use it for a PHP ZF (Zend Framework) web development.

Few days ago I've blogged How to configure vimrc for a php syntax highlightning (A Nicely pre-configured vimrc to imrpove the daily text editing experience

This enhancements significantly improves the overall PHP code editing with VIM. However I felt something is yet missing because I didn't have the power and functunality of a complete IDE like for instance The Eclipse IDE

I was pretty sure that VIM has to have a way to be used in a similar fashion to a fully functional IDE and looked around the net to find for any VIM plugins that will add vim an IDE like coding interface.

I then come accross a vim plugin called VIM Prokject : Organize/Navigate projects of files (like IDE/buffer explorer)

The latest VIM Project as of time of writting is 1.4.1 and I've mirrored it here

The installation of the VIM Project VIM extension is pretty straight forward to install it and start using it on your PC issue commands:

1. Install the project VIM add-on

debian:~$ wget https://www.pc-freak.net/files/project-1.4.1.tar.gz
debian:~$ mv project-1.4.1.tar.gz ~/.vim/
debian:~$ cd ~/.vim/
debian:~$ tar -zxvvf project-1.4.1.tar.gz

2. Load the plugin

Launch your vim editor and type : Project(without the space between : and P)
You will further see a screen like:

vim project entry screen

3. You will have to press C within the Project window to load a new project

Then you will have to type a directory to use to load a project sources files from:

vim project enter file source directory screen

You will be prompted with to type a project name like in the screenshot below:

vim project load test project

4. Next you will have to type a CD (Current Dir) parameter
To see more about the CD parameter consult vim project documentation by typing in main vim pane :help project

The appearing screen will be something like:

vim project extension cd parameter screen

5. Thereafter you will have to type a file filter

File filter is necessary and will instruct the vim project plugin to load all files with the specified extension within vim project pane window

You will experience a screen like:


vim project plugin file filter screen

Following will be a short interval in which all specified files by the filter type will get loaded in VIM project pane and your Zend Framework, PHP or any other source files will be listed in a directory tree structure like in the picture shown below:

vim project successful loaded project screen

6. Saving loaded project hierarchy state

In order to save a state of a loaded project within the VIM project window pane you will have to type in vim, let's say:

:saveas .projects/someproject

Later on to load back the saved project state you will have to type in vim :r .projects/someproject

You will now have almost fully functional development IDE on top of your simple vim text editor.

You can navigate within the Project files loaded with the Project extension pane easily and select a file you would like to open up, whenever a source file is opened and you work on it to switch in between the Project file listing pane and the opened source code file you will have to type twice CTRL+w or in vim language C-w

To even further sophisticate your web development in PHP with vim you can add within your ~/.vimrc file the following two lines:

" run file with PHP CLI (CTRL-M)
:autocmd FileType php noremap <C-M> :w!<CR>:!/usr/bin/php %<CR>
" PHP parser check (CTRL-L)
:autocmd FileType php noremap <C-L> :!/usr/bin/php -l %>CR>

In the above vim configuration directovies the " character is a comment line and the autocmd is actually vim declarations.
The first :autocmd … declaration will instruct vim to execute your current opened php source file with the php cli interpreter whenever a key press of CTRL+M (C-m) occurs.

The second :autocmd … will add to your vim a shortcut, so whenever a CTRL+L (C-l) key combination is pressed VIM editor will check your current edited source file for syntax errors.
Therefore this will enable you to very easily periodically check if your file syntax is correct.

Well this things were really helpful to me, so I hope they will be profitable for you as well.
Cheers 🙂

Skype remove word completion / Howto Disable spellcheck autocorrect on Mac OS X, Android Phones Tablets and IPhone iOS

How-to-disable-auto-correct-on-MacOS-X-android-and-iphone

I've recently upgraded my wife's Mac Book Air Mac OS X release from Mountain Lion to latest available OS X release Yosemite and after upgrade the old version of Skype used for about 3 years without any problems (except camera issues due to mac OS X bug the old post is here) stopped working (did crashed) on Skype launch so I took few minutes to upgrade Skype as well from Skype.com Skype for Mac official download page after the quick and unproblematic Skype re-install, Skype client was back to normal with a shiny new outlook and on a first glimpse all worked like a charm but …

On the next day when I took use of temporary the upgraded Mac Book Air with the fresh new OS X Yosemite and Skype's latest app to to do a quick login with my Skype credentials noticed a very annoying autocorrect (auto spelling)  Skype behavior on any new input text message.

I have to admit the idea of autocorrect feature on a system wide scale is great however quick keyboard typers like me who are used to type more than a letter per second use to type so quickly that occasinally you do errors which you're quick to fix but anyhow errors are automatically corrected in a way that you have to retype the whole word quite often which makes your typing a hellish experience. Then the same auto-correct feature becomes a terrible experience and on any device I notice this behavior I tend to remove it immediately.

I remember  the same dictionary auto-spell check / corect behavior was present on my Android run ZTE blade 3 mobile after first Mobile boot and also present on my current iPhone 5 iOS and thus the first thing I did once I start using it is to remove autocorrect (auto spelling) feature and relax the irritation of it.

Just in case if you need to disable Spellcheck auto-correct on Android Phone or Tablet do it from

Settings -> Language & input

android-phone-tablet-disable-autocorrect-spell-check

If you happen to be using also IPhone 5 as me or  Iphone 6 / 7 to disable AutoCorrect feature on SMSes / Skype / Viber and other applications do it from Phone's:

Settings -> General

disable_Turn_off_AutoCorrect_in_IPhone_iOS

Shortly I've noticed that the auto-correct feature does not only mess up your typing in Skype but also in Mail and TweetDeck and generally any open application where you can type on Yosemite.


I've took the time to investigate quickly what was causing the new feature that bugged me so much online and came to this nice little article How to turnoff autocorrect on Mac OS X 10.11 El Captain

As the article revealed to Turn off the autocorrect Mac OS X feature you I have to go:

Finder -> System Preferences

 

stop-skype-autocorrect-annoying-macosx-yosemite-system-preferences-menu-screenshot

Click on Keyboard -> Text
and turn  Autocorrect off by unchecking Correct spelling automatically

stop-skype-autocorrect-annoying-macosx-yosemite-system-preferences-keyboard-menu-screenshot

By doing this autocorrect spelling is disabled for all applications, however for some people it might be handy to leave the correct feature for Mail app or Microsoft Office (Microsoft Word / Excel) etc. and only turn off (disable) the autorrect feature per application side.

You can  do this in the separate Applications (of choise where you need auto spelling) from  Edit Menu under Spelling and Grammer and enable / disableCheck Spelling While Typing

Tadam Enjoy ! 🙂

 

Drawing GANTT Charts and Project Management on Linux, (Microsoft Project substitute for Unix)

Tuesday, October 12th, 2010

I'm studying Project Management, right now. In that spirit of thoughts I and a couple of other guys are building a Project Plan.
As it Project Plan it's necessary to put a GANTT Chart in it to show visually the project timeline (the phases), the duration and the inter-relation between the different tasks which leads the project to an actual completion.

After a bit of thorough research online on available software to deal with project management and particularly, ones that are capable to build a GANTT charts on Linux / BSD.

I've come with the following list of software capable to be a substitute for the Microsoft Project software.
Redmine GANTT Chart

GANTT chart Redmine

1. Gantt Project
GANTTProject chart GANTTProject Chart

2. Gnome Planner
Planner GANTT Gnome Chart Planner GANTT Chone Chart

3. Task Juggler Project Manager with GANTT Capability for (KDE)
Task Juggler

4. JxProject – This software is not free, though it can be considered almost free
Take a look also at:
5. Trac , though it doesn't really support GANTT charts it's a lovely software to be used for PM.
Trac Project Management

Another option you have is to try out:
6. PHProjekt

Update 20.09.2016 – PHPProject Old download link is no longer active

It is this link http://www.phprojekt.com/, but the page doesn’t seem to be active any more. I thought you might want to update.

If you are looking for an alternative please check out http://wiht.link/PHProjekt-PM, it may make a suitable replacement.

Kind Regards,
Tom Wilcox


That piece of softwre really looks promising, especially if we consider that it's web based and how much essential is today to have an anline tools for doing the ordinary desktop jobs.

You can even check an online demo of the PHPProjekt software here

If you're a type of KDE user you definitely has to try out Kplato

As I've tested the software the software is easy to be used, however it still is missing some essential parts that Microsoft Project includes so it's not 100% substitute.
Also it's not able to open Microsoft Project (MPP) files, neither able to save the charts in the .mpp format.

Moving ahead I've came across DotProject DotProject Gantt Chart
DottProject Gantt Chart

I haven't took the time to test it myself but however, as I go through the software website the project looked quite good.
Lastly you can take a look at: 7. PStricks as a mean of project management, however I think it doesn't support GANTT chart building.

use-remote-dns-on-mozilla-firefox-howto-windows-linux-logo.svg

If you're using Mozilla Firefox browser to browse the Web with Traffic Tunneling via SSH Tunnel to your own Linux server like I do in order to prevent yourself traffic to be sniffed from your Work corporate computer (as most of the corporations such as IBM / Hewlett Packard / Concentrix etc. are forcing all employee PC traffic to be  to be transported via default set Windows Corporate Proxy active for all browsers.

Then you will certainly also want to prevent the DNS requests to be not logged somewhere in your Corporate IT department thus the question arises:

How to force DNS requests to be made through the Proxy server (SSH host)?

Nomatter where you're using Firefox browser with advanced proxying plugin such as FoxyProxy FF add-on or the default Proxy FF features the DNS lookups might end up in Corporate set DNS servers often forced for the computer / notebook and impossible to be changed to a custom ones as many of the Corporation internal Sharepoints and domains are only visible from their internal networks.

Thanksfully in newer versions there is an easy way to do it directly from Visual menus via:

Tools -> Options -> Advanced -> Network -> Settings

You will get a screen like below:
 

firefox-use-proxy-remote-dns-howto-screenshot

Just tick the Remote DNS and that will force Firefox to query remote Proxy server proxy DNS

 

If you happen to be running older Firefox which doesn't have the Remote DNS tick you can also try to set the setting manually:

 

  1. In firefox type this in your address bar:

    about:config

  2. Click I'll be careful I  promise.

  3. In the filter textbox, type: proxy

  4. Find the preference name called *network.proxy.socks_remote_dns*. Double click it to set it to true.

How to show country flag, web browser type and Operating System in WordPress Comments

Wednesday, February 15th, 2012

!!! IMPORTANT UPDATE COMMENT INFO DETECTOR IS NO LONGER SUPPORTED (IS OBSOLETE) AND THE COUNTRY FLAGS AND OPERATING SYSTEM WILL BE NOT SHOWING INSTEAD,

!!!! TO MAKE THE COUNTRY FLAGS AND OS WP FUNCTIONALITY WORK AGAIN YOU WILL NEED TO INSTALL WP-USERAGENT !!!

I've come across a nice WordPress plugin that displays country flag, operating system and web browser used in each of posted comments blog comments.
Its really nice plugin, since it adds some transperancy and colorfulness to each of blog comments 😉
here is a screenshot of my blog with Comments Info Detector "in action":

Example of Comments Info Detector in Action on wordpress blog comments

Comments Info Detector as of time of writting is at stable ver 1.0.5.
The plugin installation and configuration is very easy as with most other WP plugins. To install the plugin;

1. Download and unzip Comments Info Detector

linux:/var/www/blog:# cd wp-content/plugins
linux:/var/www/blog/wp-content/plugins:# wget http://downloads.wordpress.org/plugin/comment-info-detector.zip
...
linux:/var/www/blog/wp-content/plugins:# unzip comment-info-detector.zip
...

Just for the sake of preservation of history, I've made a mirror of comments-info-detector 1.0.5 wp plugin for download here
2. Activate Comment-Info-Detector

To enable the plugin Navigate to;
Plugins -> Inactive -> Comment Info Detector (Activate)

After having enabled the plugin as a last 3rd step it has to be configured.

3. Configure comment-info-detector wp plugin

By default the plugin is disabled. To change it to enabled (configure it) by navigating to:

Settings -> Comments Info Detector

Next a a page will appear with variout fields and web forms, where stuff can be changed. Here almost all of it should be left as it is the only change should be in the drop down menus near the end of the page:

Display Country Flags Automatically (Change No to Yes)
Display Web Browsers and OS Automatically (Change No to Yes

Comments Info Detector WordPress plugin configuration Screenshot

After the two menus are set to "Yes" and pressing on Save Changes the plugin is enabled it will immediately start showing information inside each comment the GeoIP country location flag of the person who commented as well as OS type and Web Browser 🙂

How to mount NFS network filesystem to remote server via /etc/fstab on Linux

Friday, January 29th, 2016

mount-nfs-in-linux-via--etc-fstab-howto-mount-remote-partitions-from-application-server-to-storage-server
If you have a server topology part of a project where 3 (A, B, C) servers need to be used to deliver a service (one with application server such as Jboss / Tomcat / Apache, second just as a Storage Server holding a dozens of LVM-ed SSD hard drives and an Oracle database backend to provide data about the project) and you need to access server A (application server) to server B (the Storage "monster") one common solution is to use NFS (Network FileSystem) Mount. 
NFS mount is considered already a bit of obsoleted technology as it is generally considered unsecre, however if SSHFS mount is not required due to initial design decision or because both servers A and B are staying in a serious firewalled (DMZ) dedicated networ then NTS should be a good choice.
Of course to use NFS mount should always be a carefully selected Environment Architect decision so remote NFS mount, imply  that both servers are connected via a high-speed gigabyte network, e.g. network performance is calculated to be enough for application A <-> to network storage B two sides communication not to cause delays for systems end Users.

To test whether the NFS server B mount is possible on the application server A, type something like:

 

mount -t nfs -o soft,timeo=900,retrans=3,vers=3, proto=tcp remotenfsserver-host:/home/nfs-mount-data /mnt/nfs-mount-point


If the mount is fine to make the mount permanent on application server host A (in case of server reboot), add to /etc/fstab end of file, following:

1.2.3.4:/application/local-application-dir-to-mount /application/remote-application-dir-to-mount nfs   rw,bg,nolock,vers=3,tcp,timeo=600,rsize=32768,wsize=32768,hard,intr 1 2


If the NTFS server has a hostname you can also type hostname instead of above example sample IP 1.2.3.4, this is however not recommended as this might cause in case of DNS or Domain problems.
If you want to mount with hostname (in case if storage server IP is being commonly changed due to auto-selection from a DHCP server):

server-hostA:/application/local-application-dir-to-mount /application/remote-application-dir-to-mount nfs   rw,bg,nolock,vers=3,tcp,timeo=600,rsize=32768,wsize=32768,hard,intr 1 2

In above example you need to have the /application/local-application-dir-to-mount (dir where remote NFS folder will be mounted on server A) as well as the /application/remote-application-dir-to-mount
Also on server Storage B server, you have to have running NFS server with firewall accessibility from server A working.

The timeou=600 (is defined in) order to make the timeout for remote NFS accessibility 1 hour in order to escape mount failures if there is some minutes network failure between server A and server B, the rsize and wsize
should be fine tuned according to the files that are being red from remote NFS server and the network speed between the two in the example are due to environment architecture (e.g. to reflect the type of files that are being transferred by the 2)
and the remote NFS server running version and the Linux kernel versions, these settings are for Linux kernel branch 2.6.18.x which as of time of writting this article is obsolete, so if you want to use the settings check for your kernel version and
NTFS and google and experiment.

Anyways, if you're not sure about wsize and and rise, its perfectly safe to omit these 2 values if you're not familiar to it.

To finally check the NFS mount is fine,  grep it:

 

# mount|grep -i nfs
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
server-hostA:/application/remote-application-dir-to-mount on /application/remote-application-dir-to-mount type nfs (rw,bg,nolock,nfsvers=3,tcp,timeo=600,rsize=32768,wsize=32768,hard,intr,addr=1.2.3.4)


That's all enjoy 🙂

 

 

Windows add / delete services command sc.exe create/delete – Create or Delete services

Thursday, April 9th, 2015

sc-exe-command-line-program-to-create-delete--service-start-stop-service-on-ms-windows
If you end up in situation where you need to delete or create services from current existing ones with a batch script because it is existing on multiple servers and you want to automate / deploy it via batch (.bat) script you will have to use sc.exe tool – Service Controller Command Tool

SC.EXE command  is standard windows console tool to create and delete services. If you want to create a new service, you can use the "create" parameter.

1. Deleting Service with Windows Service Controller Tool

Deleting service is very easy to do you just have to know the service you like to remove not to be listed or Automatically start

sc delete SERVICE_NAME_TO_BE_REMOVED


Below is a real time example on how to remove Apache webserver configured to auto-start

 

sc.exe delete ApacheService

[SC] DeleteService SUCCESS

2. Create / Add service to existing to auto start on Windows

Before running sc.exe create command with arguments for service you will need to know following info:

  • What will be the Service Name: A single word to name the new service.
  • Full Binary Path: The path name where the executable program for new service is currently located.
  • Dispaly Name for service: A short name for the new service.

 

C:\Windows>sc.exe create ApacheService 
   binPath= "C:\local\apache\bin\httpd.exe -k runservice" 
   DisplayName= "Apache Server"

 

[SC] CreateService SUCCESS


Once service is added to be showing in services.msc GUI  you can start the newly added Apache service with:

 

C:\Windows>sc.exe start ApacheService

 

SERVICE_NAME: ApacheService
   TYPE               : 10  WIN32_OWN_PROCESS
   STATE              : 2  START_PENDING
                      (NOT_STOPPABLE,NOT_PAUSABLE,IGNORES_SHUTDOWN)
   WIN32_EXIT_CODE    : 0  (0x0)
   SERVICE_EXIT_CODE  : 0  (0x0)
   CHECKPOINT         : 0x2
   WAIT_HINT          : 0x7530
   PID                : 2552
   FLAGS              :


To stop the ApacheService or any other service:

 

C:\Windows>sc.exe stop ApacheService

SERVICE_NAME: ApacheService
   TYPE               : 10  WIN32_OWN_PROCESS
   STATE              : 3  STOP_PENDING
                      (NOT_STOPPABLE,NOT_PAUSABLE,IGNORES_SHUTDOWN)
   WIN32_EXIT_CODE    : 0  (0x0)
   SERVICE_EXIT_CODE  : 0  (0x0)
   CHECKPOINT         : 0x4
   WAIT_HINT          : 0x7530


To get the status of a running service lets say the recently ran ApacheService:

C:\Windows>sc.exe query ApacheService

 

SERVICE_NAME: ApacheService
   TYPE               : 10  WIN32_OWN_PROCESS
   STATE              : 4  RUNNING
                      (STOPPABLE,NOT_PAUSABLE,IGNORES_SHUTDOWN)
   WIN32_EXIT_CODE    : 0  (0x0)
   SERVICE_EXIT_CODE  : 0  (0x0)
   CHECKPOINT         : 0x0
   WAIT_HINT          : 0x0


As you see from above output the STATE of service is RUNNING. If Apache Webserver was not running you will get an error like:

[SC] EnumQueryServicesStatus:OpenService FAILED 1060:
The specified service does not exist as an installed service.

 

Enjoy sc-ing 🙂
