Share Files with Computers not in Your Windows Domain

How to share a folder and its files with computers outside of the Windows domain. This is a generally bad idea, but if you need to do it, it's possible.

My Second Angular Directive - Menus

This was downright difficult. The good news is that the code got a little shorter, the HTML is a LOT shorter, the menu settings are in a shorter config file, and the direct manipulation of the DOM has reduced significantly.

When the user clicks on a menu item, here's what happened:

The original scanned the DOM to toggle off the current item. Then toggled the new item.

Now, the new version maintains a copy of the menu configuration, and alters this model. A loop scans the model and sets a "selected" bit, then triggers the animations.

My First AngularJS Directive: Stretchdown - stretches an element to the bottom of the window.

I've made may first directive! OK, not that special, but to me it is. This is one of the more difficult features I've come across in Angular, and I still don't really "get it".

I'm not even going to do a code walkthrough, because I can't really explain it well. The easy part is calculating the height the element should be. The tricky part is implementation.

Chrome Rendering Glitch with Label's Padding in Points (PT), Even Values

I have to learn the Chromium bug reporting system. Found an interesting rendering bug if, on a label, you specify a padding with an even number of points (pt), the rendering is shifted up a little bit, and the border can disappear if it's adjacent to another element.

Two examples are attached, differing only in the amount of padding.

Maybe it's a difference in how the values are calculated and either rounded off or truncated.

The problem goes away if you use pixels instead of points.

Why is Markdown Cool?

I went to the UseR conference, and R-Markdown was all the rage. My boss/coworker/?? asked me what was so cool about it. I've been using plain Markdown around a year, and think it's kind of cool, but my initial impression was that Markdown was kind of lame.

Chinese-American Cantonese Restaurants in Los Angeles

Personally, I prefer the Hong Kong style places in Monterey Park and Alhambra, and got used to them in the past 30 years or so, but it's not true that LA doesn't have old fashioned Chinese-American food anymore. People say it, but that's because they're eating at fusion restaurants or a newer place.

Improved Learning with Transcripts of Video Tutorials

I'm learning AngularJS and noticed a few things going on. First is that there's a great tutorial out there called Angular JS in 60 Minutes Ish by Dan Wahlin. It's really good, and it's a little different from most tutorials. It read like the script of a screencast - and I thought it *was* the script of a screencast.

It's actually the inverse. It's the transcript of the screencast, and the images were taken from the screencast.

SMDR Logger for IP Office and other PBXs, logs SMDR to syslog

This is a work in progress. I wanted to log all our calls and found out that there's a feature in IP Office called SMDR that sends logs to a server.

There were a few programs that could receive these logs, but I couldn't find one that just logged the lines to a syslog. After initally reading how to do it in Python and looking a the Perl code from SimpleSMDR, it seemed like too much code. This small C program, smdr-syslog, to does what I want.

The attached file contains a better version of the program, with an installer for Ubuntu Linux.

Restore Specific Files from a Huge .BKF NTBackup.exe file

I like using NTBackup.exe on the old VMs, but discovered that if you don't keep up on the backup rotations, you will have a very hard time doing restores. The NTBackup.exe restore doesn't make it easy to restore all incrementals of a folder.

WordPress: Setting the META Description to part of the page's content

This code puts the first paragraph of the post into the description meta tag. It tries to strip out leading whitespace and any tags. If you insert an image, it should be stripped.

Re: Why Most Developers Should Avoid Apple's New Swift Language

http://www.huffingtonpost.com/ga...

I don't agree with this article, at least on the points he made.

> Swift is irrelevant to the majority of mobile audiences

Yes, but so are iOS apps, and so are Android apps. These are all much smaller than the total smartphone market... but they are larger than other software markets.

> The best use case for Swift is iOS exclusive games

This is true, though "exclusive" doesn't need to be part of it.

Raspberry Pi NAS Backup

Last year, I got one of those little Raspberry PI (R-Pi) devices. It's pretty cool, but in the end it's a little PC. Since there's a big bad PC under the desk, the R-Pi didn't get much use. Also, I'm a chicken hardware hacker and so I never put anything onto the GPIO pins.

R Database Connection Class in RS (R5 S5)

I'm learning R, and it's been interesting. The weird part is that I don't know stats. Yes, I know standard deviation, mean deviation, and easy stuff, but those are one-liners in the R tutorials. What I know in stats amounts to around 1/4 to 1/2 a page of the R tutorial. So to compensate, I have a stats text from the thrift store, so I'll eventually be less than a total ignoramus about what I'm reading.

One of the twists of what I'm messing with is that all our data is in a database. The normal mode of operation for R users is to load the entire data table into memory and do awesome reporting on it. Where I'm at, for better or worse, is more like a traditional web application with a database back end.

A problem with this is that MySQL lets me have only 16 connections going at the same time. I'm not sure if it's the driver, but I'll assume that. Since RStudio holds the connections, coding a lot of changes eventually leads to a lot of lost database connection handles, and eventually running out of connections.

Installing R Packages Globally (for rApache)

For general instructions, see: http://cran.r-project.org/doc/manuals/R-admin.html#Managing-libraries.

In Ubuntu Linux, the path to the global libraries is: /usr/local/lib/R/site-library/

To install there, you can do install.packages(c('foo'), '/usr/local/lib/R/site-library/')

or take advantage of the built in variable: install.packages(c('foo'), .Library.site[1])

Check that .Library.site has the values you need.

You can also use R CMD INSTALL -l /path/to/library foo

Weird Network Fault Due to Unknown thing on the End of the Wire

I was called in to help fix a network that had been discombobulated. I didn't end up fixing it, but one staffer there did the trick by disconnecting a switch with a bunch of wires plugged into it.
