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.

Using Muriatic Acid (Pool Acid) to Clean the Toilet

We're in full drought mode in LA, and that means we follow the eleventh comandment: if it's yellow, let it mellow, and if it's brown, flush it down.

Salsa Petition Counts with Scrapy the Python Web Scraper

I was feeling like crap, so after taking the day off and taking a nap, I spent several hours learning Scrapy. Scrapy is a pretty awesome website scraper. This example logs into a website, extracts some data, and stores it locally.

CSS Hints for Technoids Who Forgot to Learn CSS

Here's a bit of the article:

Dang, but it took me forever to learn CSS. Maybe I should have used a book. Here, I'm going to share with you the hard-found knowledge, presented using technical programmer jargon. (Revised in 2014.)

What is Cascading Style Sheets (CSS)? The typical answer is that it's a way to separate the way a page looks from the the underlying HTML, which describes the structure of the document.

Radeon R5 230 on Ubuntu Linux 13

It works. Haven't bought a graphics card since the mid 1990s, but did this because Gnome 3 feels a lot smoother with some extra cycles and memory. All the eyecandy effects now seem to run at around 20 fps, and the colors are nicer. Before, they were more like 10 fps and jumpy. This shows up in lspci as VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Caicos [Radeon HD 6450/7450/8450]. Seems to be a bit of a power hog, but it doesn't use a fan, so it's not going to burn too much coal.

CSS Stylesheet Switcher Widget

This snippet of code can be modified and used to change the stylesheet on your page. I set it up to work against a layout extracted from Salsa, but it should work on generic pages. It's good for demos, discussions about a layout, trying different colors, etc.
