OPTIMIZE YOUR SYNOLOGY NAS FOR DOWNLOADING The download will be added to the queue. If you use an adaptation of my unpacker script, it will already automatically scan /volume1/downloads/_queue for any new torrent or nzb task.. Tools. These programs may take up a little bit of space, but won't be active in memory until you call upon them (except for cron), so feel free to install without performance loss: CREATE DAEMONS IN PHP Execute. Just make your daemon script executable, and then execute it: $ chmod a+x ./logparser.php $ ./logparser.php. Check. Your daemon has no way of communicating through your console, so check for messages in: $ tail /var/log/logparser.log. And see if it's still running: $ ps uf -C logparser.php. Kill. ANALYZE HTTP REQUESTS WITH TSHARK The command below captures all port 110 traffic and filters out the 'user' command and saves it to a text file (from Mark's notes ): $ tshark -i 2 -f 'port 110' -R 'pop.request.parameter contains ' user '' > /tmp/pop_users.txt.

IMPROVE MYSQL INSERT PERFORMANCE March 31, 2009. Improve MySQL Insert Performance. Sometimes MySQL needs to work hard. I've been working on an import script that fires a lot of INSERTs. Normally our database server handles 1,000 inserts / sec. That wasn't enough. So I went looking for methods to improve the speed of MySQL inserts and was finally able to increase this number to ALLOW WINDOWS USERS TO RESTART SERVICE So first we need to: Download the Windows Server 2003 Resource Kit Tools. Install it. Open a command prompt ( cmd.exe) Change to installation directory ( cd "C:\Program Files\Windows Resource Kits\Tools") Prerequisite: Access to SC Manager. Your users need to be able to access this service as a prerequisite. If you want your

changes to be user

CAT A FILE, WITHOUT THE COMMENTS Cat a File, Without the Comments. I recently had to install a couple of squid servers to act as reverse proxies for a webcluster. You can teach the squid server to stand in between in the end users and the webservers, and to store all the static content ( .jpg .flv .css .htm for example ) in the RAM. This saves a lot of I/O and bandwidth on the SCHEDULE TASKS ON LINUX USING CRONTAB The crontab (cron derives from chronos, Greek for time; tab stands for table) command, found in Unix and Unix-like operating systems, is used to schedule commands to be executed periodically. To see what crontabs are currently running on your system, you can open a terminal and run:

$ sudo crontab -l.

THE UNIVERSAL MAKEFILE FOR JAVASCRIPT The :-lets us specify a default value, so that if I run npm run minify on the command-line without setting any environment, app is chosen as a default minify output. Running npm run build:plugins, overrides this defaults and minifies the plugins bundle for me.. For a larger example, check out Google's Addy Osmani's Gist that demonstrates his real world task runner in npm scripts.

INTRODUCING LANYON

January 4, 2017. Introducing Lanyon. This project also has its own homepage at lanyon.io. Lanyon is a static site generator. It functions as a wrapper around Jekyll, Webpack, and BrowserSync, in an attempt to give you the best of all worlds. Lanyon allows you to build and refresh assets instantly and offers fast and reliable file watching. BEST PRACTICES FOR WRITING BASH SCRIPTS This project now has its own homepage at bash3boilerplate.sh.. I recently tweeted a few best practices that I picked up over the years and got some good feedback. I decided to write them all down in a

blogpost.

PHP: TIFF2PDF

ps2pdf: Convert PostScript to PDF using Ghostscript. Imagick (The tiff2ps Step) Imagick is a native PHP extension to create and modify images using the ImageMagick API. It's twice as fast as making system calls to ImageMagick commands and in this case I am using Imagick to create the in-between .ps (PostScript) file. GITHUB SPRING CLEANING Starting is simple. You create a container repo on Github named deprecated, add it as an origin to existing repos, force push current master to a named branch, and done. However, spring cleaning is no fun without automation, so we wrote a script to do this for you. Just change the repo_sources and repo_destiny variables. RUN NODE.JS AS A SERVICE ON UBUNTU We decided to go conventional and chose www-data. We found the easiest way was to prepend the Node executable with a sudo like this: exec sudo -u www-data /usr/local/bin/node. Don't forget to change your export HOME accordingly. Restarting Your Node.js Daemon. This is so ridiculously easy.. $ start yourprogram $ stop yourprogram. GOING FROM MACOS TO UBUNTU It's not the first time I'm switching to Ubuntu. I've been, as they say, around the block when it comes to operating systems. I started out on MS, from DOS to XP, then Ubuntu from 5.10 Breezy to 9.10 Karmic, then on Apple from OSX 10.5 Leopard to macOS 10.14 Mojave. BLOCK BRUTE FORCE ATTACKS WITH IPTABLES July 28, 2007. Block Brute Force Attacks With Iptables. Since 2005 there has been an immense increase in brute force SSH attacks and though Linux is pretty secure by default, it does not stop evil programs from indefinitely trying to login with different passwords. Without proper protection your server is a sitting duck waiting for a
