I was trying to get a printer set up on a Chromebook and after looking through its list for the right model, it wasn’t there. It suggested I give it a PPD file. After some searching, I learned that you can find some compressed PPD files if you download the right Postscript Windows driver from
Sometimes I’m not so great at managing my time. So it makes sense that I’m sometimes not great at managing anyone else’s time either. When it comes to screen time for kids, there needs to be a limit set for how much they use it. We have an Amazon Fire tablet, and it comes with
[crayon-5dff2e06ba305789140644/] Does this look familiar? Maybe you need more fiber in your diet. Or maybe you need THIS: [crayon-5dff2e06ba30e229779442/] You’re welcome.
I have an old thin client that I upgraded to a home server by adding some additional RAM and storage. I noticed after a recent kernel upgrade that the system seemed sluggish at times, despite doing nothing in particular at the time. top showed that a kworker process was using CPU, not all of it,
I’m running Selfoss RSS reader and loving it! One thing I don’t love is that it logs me out frequently (BTW, I’m running Apache php-fpm on Debian Jessie). But I think I found a solution. Try adding this to a file called .user.ini in the document root of Selfoss: [crayon-5dff2e06ba679083557739/] The 604800 means one week.
Note: I’m running my Raspberry Pi as a server, and NetworkManager is not installed. I discovered that if you want to manually assign search and nameserver entries in your /etc/resolv.conf file, you can’t just add the relevant entries to static entry in /etc/network/interfaces: [crayon-5dff2e06ba704869638171/] For some unknown reason, the resolvconf utility will still attempt to
Just saw this on One Thing Well, and it made me so nostalgic about my early years on *nix and the net. A weather service fed over the finger protocol. [crayon-5dff2e06ba774802800716/]
I find that using an idiom like [crayon-5dff2e06ba7f9593698532/] is so useful. It replaces the replstr (“%” in this example) with all the arguments at once, or as many as can fit without going over the system’s limit. I couldn’t believe it when I learned that the GNU version of xargs lacks this flag. Yes, it’s
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
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.
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 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
