What to do about PRISM is unclear as of yet

Dave Farquhar — Mon, 24 Jun 2013 11:00:09 +0000

I haven’t written a lot yet about Mr. Edward Snowden and the NSA PRISM program. I will in time, but want to be careful not to be spreading misinformation, and not to merely be repeating what everyone else says. There’s

Another easy Apache tweak

Dave Farquhar — Wed, 20 Feb 2013 20:30:34 +0000

I ran my site through Google Page Speed on Tuesday, and scored a surprising 88 out of 100–higher than I expected. Getting above 90 is going to take some optimizations on files that WordPress updates may change, so I’m hesitant

A fast way to turn lots of images into an Adobe Acrobat PDF file

Dave Farquhar — Mon, 03 Dec 2012 10:37:08 +0000

I have a collection of magazine scans that, inconveniently, came as a series of JPG images rather than as PDFs that are more conducive to reading. I wanted PDFs, so I found a way to turn lots of images into an

Unix-to-Windows copies with PSCP

Dave Farquhar — Tue, 13 Mar 2012 00:47:01 +0000

I’ve been moving files between Linux servers, and to and from Windows boxes, as part of my server migration. I started to write about how I’ve been doing it, but it seemed oddly familiar. Yep, I’ve written about SCP and

Pipe output to the clipboard in Windows

Besides all the changes to the GUI that happened post-Windows XP, they also made one useful change to the command prompt. When you run a command, it’s now possible to pipe output to the clipboard. If you’re like me and

More tips for playing with toy trains

As you can probably guess from the length of time between postings, the Lionel has proven to be quite the distraction. A welcome one, but definitely a distraction.

Easy and secure remote Linux/Unix file transfers with SCP

Dave Farquhar — Tue, 02 Dec 2003 23:42:58 +0000

Sometimes you need to transfer files between Linux boxes, or between a Linux box and some other box, and setting up Samba or some other form of network file system may not be practical (maybe you only need to transfer a couple of files, or maybe it's just a one-time thing) or possible (maybe there's a firewall involved).

Optimizing Web graphics

Gatermann told me about a piece of freeware he found on one of my favorite sites, tinyapps.org, called JPG Cleaner. It strips out the thumbnails and other metadata that editing programs and digital cameras put in your graphics that isn't necessary for your Web browser to render them. Sometimes it saves you 20K, and sometimes it saves you 16 bytes. Still, it's worth doing, because more often than not it saves you something halfway significant.
