Been using robocopy for a while and I thought it would be useful to list a few things it can do: Delete long directories or filenames: robocopy /purge c:\empty [to be deleted directory] Copy all drive/directories/files without changing any attributes: robocopy /copyall /mir /xj [sourcefile] [destination] Copy all drive/directories/files excluding duplicates: robocopy /copyall /mir /xj […]
A while ago I found a bug in imagesloaded js where images failed to appear after loading. This seems to be attributed by the “fixed” timer used by imagesloaded js to detect if an image has completely loaded. Consequently larger images taking longer loading time exceeded the specified fixed time. To rectify this, the timer […]
Ruby 2.1 64-bit for Windows have problem with sqlite3 gem install where it can’t find the native library. You would get an “unable to find sqlite3_native.so” or “checking for sqlite3_libversion_number() in -lsqlite3… no”. To fix this: Download source file from sqlite.org and unzip to a directory. Eg. C:\sqlite3 Download the 64-bit dll from here and […]
I find Steve Borgatti’s recent book (2013) on Analyzing Social Networks to be a good guide in introducing how you can use graph theory to describe social network. I remember reading some of his guides a few years back which caught my attention but they are all now translated into this book.
If you want to sync files between computers without any server or resorting to commit, push, etc… then Unison is a simple utility to do that.
TP-Link routers/AP seems to have problem with the OpenWRT firmware with wifi constantly dropping. A check on system log reveals the error message “disconnected due to excessive missing ACKs”. To circumvent this problem, edit /etc/config/wireless file and append ‘option disassoc_low_ack 0’. Update: This problem is fixed in the latest OpenWRT.
There are three different memory allocator for the Linux kernel – SLAB, SLUB and SLOB. For larger system, Linux kernel uses SLAB until kernel version 2.6.23 and now the default is SLUB. SLOB on the otherhand is for small embedded system. If you’re compiling any modules and get an undefined reference to malloc_sizes error during […]
Referring to my previous post, it seems that SMTP authentication fails when authentication is not done within a workstation logged into the NT realm. I’ve now attempted to change the PHPMailer source code though I will need an Exchange server to test it. To use it, replace the file PHPMailer/extras/ntlm_sasl_client.php with the modified one. So […]
Writing UL/LI table in HTML is always a tedious task especially when the dataset is large. So I’ve created a very simple tool long ago that can auto generate UL/LI table. This is written in Excel VBA and can place the elements horizontally or vertically. The added benefit for doing this in Excel is to […]
A while ago while using PHPMailer, I noticed there is a lack of Microsoft Exchange support for sending e-mail on STMP using NTLM authentication. Perhaps the close endedness of the proprietary protocol makes it hard for developer support. One particular file I’m very interested in is the ntlm_sasl_client.php which is pretty outdated and only supports […]
