Content Moving

Jan 30, 12:48 AM

Because I didn’t end up fleshing out this site as much as I thought, and I find that Wordpress is easier to work with, I’ve decided to merge the content from this site into my more general blog at Walter’s Rant Fest. Current articles will remain here so that I don’t break any links, but new articles and updates to existing ones will be published on my Wordpress blog.

Customer Service experience with Maha Energy/Powerex and Rayovac

'Sploded Rayovac 1800mAh NiMH rechargeable AA battery

<rant>As a proponent of voluntarism and free markets, I believe that a company should live or die according the value it brings to its customers, not through political kickbacks or regulatory capture at the expense of the taxpayers and their freedom of choice. To that end, in a truly free market, reputation is paramount and the importance of consumer reporting – both professionally and socially – cannot be understated.</rant> For this reason, I want to share my experience with two separate companies regarding a particular incident.

The products in question were a Rayovac NiMH 1800mAh rechargeable battery and a Maha Powerex MH-C9000, one of the top consumer battery chargers on the market.

Bash Script to Simplify 7z in Linux

Feb 27, 03:20 PM

I love 7zip. I use it for all of my file compression needs, exclusively. Unfortunately, in Linux, it's a bit of a PITA. Graphical utilities that support it are unreliable, and the command line utility is needlessly complicated unless you use the default options, which are suboptimal. So here's a handy little script I wrote to simplify its usage in my daily life.

Basically, all you have to do is type "7zip target" and the script will apply maximum LZMA2 compression to the file or directory as "./target.7z". You can also use "7zip *" or "7zip file_1 file_2 file_3...", and it will create one archive per argument. If you specify an output directory via -o, it will save the archives there. Spaces are supported if you use quotations.

Walter's Retro Programming

Dec 27, 11:38 AM

In my early days of geekhood, I was a part of the “wannabe hacker” crowd and, in my efforts to become a 1337 h4×0r, wrote a handful of programs for various purposes as my first foray into programming. Though of little value to me in my current activities, I thought I’d post them for others to use or admire. They were all programed in 1999-2000, give or take a year. No installation necessary, just un7zip and run. You may need the Visual Basic 6 runtime libraries. I do not have the source codes, but should I ever stumble upon them, I will post them here.

All programs here are provided free of charge, without any warranty or liability, express or implied. Though many of these programs were originally made for mischief, I have no reason to believe that they are capable of causing any major problems on the modern internet. Networks are much faster and security much better than a decade ago, and more effective tools are available from other authors. Still, you may get into trouble if you use these irresponsibly.

Linux: Enforce Recursive Ownership and Permissions of a Directory

Oct 8, 08:51 AM

On my home server is a "public" directory, where my users are able to place common files without eating into their own disk quota. The main problem I encountered in setting this up was that, when different users would write to this directory, the files would retain original ownership so that it still counted against their quotas, and others could not modify or delete them. Unfortunately, Linux does not have a simple way of enforcing recursive ownership/permissions.

Despite lots of Google surfing, I could not solve this problem and resorted to a self-invented hack...

Finally, after long months of impotent frustration, I stumbled upon the following trick, though I can't credit the original author as I don't remember the source...

Small update: added quotes to account for filenames with spaces
