Red arrow shortcut glyph on icon in Windows

Blogs, Snippets

After using the hardlink (instead of symbolic link in Link Shell Extension) I noticed this Red arrow shortcut glyph right on the source file from which I created the hardlink to other location. Strangely, Windows Explorer didn't show the hardlink indication however XYplorer showed this clearly. You may mistaken that red arrow is a shortcut but it's actually the source file. Red arrow glyph appearing on XYplorer but not in Window explorer for hardlinked source.

WP: Plugin download or update error

Snippets

There are many solutions around the web for this but for me, a temporary solution worked in a way when I made all of the root files read+write from /opt/ as below. Since I'm working on a separate copy of WP in my local drive, its not too risky to do this. $sudo chmod -R a+r+w opt/ And then removing the temporary directory (commenting out) mentioned in the wp-config.php file //define('WP_TEMP_DIR', '/opt/bitnami/apps/wordpress/tmp');//define('WP_TEMP_DIR', ABSPATH . 'wp-content/tmp/');

Arity & Currying

Blogs, Snippets

This is a series of blogs where I collect some interesting programming concepts, new things I learn Arity represents the number of arguments we pass to a function (or module). Say you may pass N args to a function. Currying is the process of reducing the number of arguments you pass to 1 but increase the number of functions to N. For Eg. To add three variables a, b and c you may write func like below function add (a,b,c){ return a+b+c; } add (45, 46, 47); Currying the same above function is then like below function add (a){ return function add (b){ return function add (c){ return a+b+c; }; }; } add (45) (46) (47); Notice how each function returns another function until the last function does the final…

My Favorite Linux Command line tools & Commands

Blogs, Snippets

Disk Space Analyzers df - command This command can quickly give a glance of how much space are consumed and left out on overall level. For example, below image shows that I have consumed 51% of my disc, so I have 49% left out. NCDU The below command worked for me in bitnami stack however there are also other commands for other OSes. The key feature about NCDU is we can analyze from the root folder and easily navigate with arrows and enter the key to see which is occupying more space. Remember to use Ctrl+Z to exit this at any time. sudo apt install ncdu Folder & File Permission Command: chmod Recursive: -RAll Read Write: a+r+w sudo chmod -R a+r+w /FOLDER/

Oracle ODBC Connection & Key Learnings

Blogs, Snippets

Using an Oracle database from LabVIEW is quite jargon journey. From Instant-Client to ODBC, OLE DB, SQL Developer etc, difference between ODBC, ODAC, OLE DB, ADO etc, all can lead one to confusion easily. NI has tried to explain well on this document, it's still not very lucid in other sources like stackoverflow. I'm not confronting here to clarify all those. I found some few key learning are worth sharing. Windows has implicit classification of files between 32bit and 64bit. If you create a file using C:\Windows\SysWOW64\cmd.exe, then it creates pure 32-bit file. Look at this link for more details. LabVIEW connects to the database provider purely based on the LabVIEW bitness. If you use 32-bit LabVIEW, then use the 32-bit data provider and UDL file.Never get confused with Oracle…

SVN Externals

Blogs, LabVIEW Blog, Snippets

If you are looking to reuse a project which already exists in another project and if you need that new project gets updates of the already existing project then-and-there, there is a very good feature in SVN called as externals to help on this kind of requirements. Advantages You can avoid multiple copies of the same source in SVN/source control repositories. Get updates from the root project as and when there is an update. So no need to manually copy the project again when there is an update. SVN-logs are maintained for the root project from the new project and hence better historical control. In case you don't need updates from root project, use specific revision to freeze to selective version. How does that works? This can be best explained…
