I would really like to rid myself of Dropbox, but all the alternatives I’ve tried are too bloated, beta- or alpha-quality stage, too complicated to set up, or just plain don’t do what Dropbox does (minus the sharing stuff, which I don’t care about). I don’t want btsync, it’s closed-source. Seafile is too complicated, and
Just a quick one-liner for posterity. [crayon-5c68ade83b1bd325200057/]
If you have a ton of posts in your WordPress blog (we have over 35K in one site at work), it turns out that the Previous and Next links on each post may be running a tough query on your database. I wanted to know why MySQL was using so much CPU and wrongly assumed
I was experiencing a pretty bad slowdown while trying to use the admin pages of a WordPress site recently. The load on the machine was quite low, so I began to suspect that it was trying to call out to external services (facebook, pinterest, etc) that might have been blocked by CSF (configserver firewall). I
I recently skimmed a paper showing the success of attacking the security of various password database file formats. The only one which withstood both the passive and active attacks was the Password Safe format.
If you have some need to OCR some text from a PDF or image file, you may want to use a tool like tesseract to do the job. But it won’t take any old input file, you’ll probably need to convert it first. The first error I got from tesseract was [crayon-5c68ade83b3e0430899834/] The Googles indicated
UPDATE: Major derp moment on my part, thinking that you needed a loop in AWK to print all but one fields. Commandlinefu just cause a forehead-slapping moment when I saw this in my feed: [crayon-5c68ade83b525418989934/] So, it seems AWK wins again. Carry on. If you’re trying to print one or more particular columns from some
Yes, the Raspberry Pi can do fast video encoding. Of course you normally wouldn’t want to re-encode any video with an ARM processor, but that’s not what we’re going to do here. We’re going to leverage the GPU. I should point out before proceeding that the input formats for re-encoding are limited in this method,
I recently wanted to move a system over to a faster, larger SSD. I didn’t want to have to re-install an OS, figure out which old files to transfer over, and then re-configure everything. That’s not a fun time in my book. Here’s what I did (on a live system, yeah!) to clone my disk.
I think I’ve tried pretty much all of them. After the Google Reader-pocalypse, one of the primary requirements was that I could host it myself. Bonus points go to apps that have configurable keyboard navigation (“j” to open the next item must be distinct from “space” to just scroll down in the browser), as well
While trying to move an older code base to a newer system and thus a newer version of PHP (5.3 -> 5.5), I knew that some of the code would need to be changed to avoid using some removed features. Specifically, I mean call-time pass by references. For those who don’t know, this is kind
This command line interface for administering WordPress is called wp-cli. It’s pretty great. I wrote a script to run from cron for updating a bunch of different WP installs in the same directory. [crayon-5c68ade83b7f0712878954/]
I noticed that I was getting emails from LFD (part of the ConfigServer Firewall package) about failing to find some added check line it was sending to syslog. The syslog message looks like this: lfd[%d]: *SYSLOG CHECK* Failed to detect check line [%s] sent to SYSLOG Of course I’ve replaced the pid with %d and
I was enjoying trying out APF on my Raspberry Pi, but I noticed that it wasn’t blocking repeat attackers the way I wanted it to. fail2ban was working the way it was supposed to work, but it only blocks temporarily, and I never figured out why the gamin back-end to continuously monitor log files didn’t
I’ve written about Locamatic before, and while it’s good at what it does, there are some definite drawbacks. For one, the most recent version is alpha quality and stated for use on Mountain Lion since prior versions won’t work anymore on a newer system. But as of this writing, Mountain Lion was two major releases
