### Microsoft Security Essentials Automatic Updates

I love Microsoft Security Essentials, but I'm annoyed by having to do the virus signature updates manually with each Windows Update. This could be because I have Windows Update set to download but let me choose which ones to install. However, you can use the Task Scheduler to automatically run the signature update every day.

AddictiveTips provides instructions, but on my 64-bit Win7 machine the file location was different.

C:\Program Files\Microsoft Security Essentials\MpCmdRun.exe SignatureUpdate
I used
"C:\Program Files\Microsoft Security Client\Antimalware\MpCmdRun.exe" SignatureUpdate
So far, so good!

### Make Firefox 4 to save passwords for ALL websites

Some websites ask web browsers to disable their password auto-complete features. This allows developers to increase the password security for important sites like banking, but can also be used for less important sites.

You can force Firefox to ignore the website settings and save all passwords, but you must then be extra vigilant about which passwords you save. Banking sites and the like will now prompt you to save the password, which you probably shouldn't do for them.

There was an easy fix for Firefox before version 4 (see this post), but there are a few hoops to jump through for the latest version. Firefox 4 packages all the necessary files into omni.jar in the program folder, which is a non-standard archive format that needs to be specially altered. Below are the directions from this comment:

0. Make a backup copy of omni.jar
1. Unzip the omni.jar (using either 7zip, Winrar)
2. Edit accordingly
3. Pack again using ZIP format + SFX option (Self-Extract)
4. Rename back to omni.jar
5. Launch Firefox!

### Better APA-style: working around hyperref and apacite problems

I'm writing an article in LaTeX using APA style, so I'm using the popular
apa.cls style. It defaults to using apacite for citations and references, which works well enough.

But if I have a URL field in the BibTeX, like I always do in JabRef to remember where I found things, it prints it for each reference wasting a lot of space and not breaking lines properly. I also like the URLs I do show to be clickable hyperlinks, and my citations and cross-references as well. You can usually do this using hyperref, but a lot of things break when using apacite and hyperref together. Here's the top of the file:
\documentclass[jou]{apa}\usepackage{hyperref}
And here is the output of pdflatex:
! Undefined control sequence.\hyper@@link ->\let \Hy@reserved@a                                    \relax \@ifnextchar [{\hyper@link@ }{\hyp...l.83 \cite{Aris09Visual}...! Argument of \@@cite has an extra }.                 \par l.83 \cite{Aris09Visual}...Runaway argument?>{\hyper@link@ }\def \reserved@b {\hyper@link@ [link]}\futurelet \@let@token \ETC.! Paragraph ended before \@@cite was complete.                    \par l.83 \cite{Aris09Visual}
Other people have had this problem before, but there aren't any great solutions. See the end for a good solution using biblatex-apa instead of apacite. If you insist on using apacite, there are instructions here for how to make things mostly work:
The simplest way to fix the problem is to put a single
instance of \protect into hyperref.sty.

Turn this:
   \def\bibcite#1#2{%     \@newl at bel{b}{#1\@extra at binfo}{%       \hyper@@link[cite]{}{cite.#1\@extra at b@citeb}{#2}%
into this:
   \def\bibcite#1#2{%     \@newl at bel{b}{#1\@extra at binfo}{%       \protect\hyper@@link[cite]{}{cite.#1\@extra at b@citeb}{#2}%
This occurs at
line 3972 in hyperref.sty [2007/02/07 v6.75r
and at
line 4939 in hyperref.sty [2008/04/05 v6.77l
(line 8328 of the corresponding hyperref.dtx ).
but this breaks the citations. Later they added additional code to the tex file:
It's really just a matter of executing APA's version of \bibcite
before doing the extra stuff that hyperref needs to create the hyper-linking (which seems to work just fine).

For example, the following coding seems to work OK.
\usepackage{apacite}\let\APAbibcite\bibcite   %%%%  add this line\usepackage{color}\definecolor{darkblue}{rgb}{0.0,0.0,0.3}\usepackage[bookmarks=true]{hyperref}\hypersetup{   pdfauthor={Salvatore Enrico Indiogine},   pdftitle={},   pdfsubject={TAMU EDCI},   pdfkeywords={},   pdfcreator={LaTeX with hyperref package},   pdfproducer={dvips + ps2pdf},   colorlinks,breaklinks,   linkcolor={darkblue},   urlcolor={darkblue},   anchorcolor={darkblue},   citecolor={darkblue}}%%%%  add the following 2 lines\let\HYPERbibcite\bibcite\def\bibcite#1#2{\APAbibcite{#1}{#2}\HYPERbibcite{#1}{#2}}
This fixes most problems, but there are still warnings and ampersands missing in the references.

A better solution for me was to use biblatex-apa with biblatex instead of apacite.

First replace \bibliography{...} at the end of your tex file with \printbibliography. Then modify the the top to look like this (note the noapacite option for apa.cls).
\documentclass[jou,noapacite]{apa} %%%% apacite is buggy with hyperref\usepackage{color}\usepackage[]{hyperref}\hypersetup{   pdfauthor={AUTHORS},   pdftitle={TITLE},   pdfkeywords={KEYWORDS},   colorlinks,breaklinks,   linkcolor={blue},   urlcolor={blue},   anchorcolor={blue},   citecolor={blue}}%%%% bilatex-apa\usepackage[american]{babel}\usepackage{csquotes}\usepackage[style=apa,hyperref,doi,url]{biblatex}\DeclareLanguageMapping{american}{american-apa}\bibliography{}

### CrashPlan local backup phones home way too much

I recently tried using CrashPlan, an online backup program that also provides a free client for local or local network backups. I was not happy when I discovered how much it phoned home for these supposedly local backups.

After watching the EFF's presentation The Law of Laptop Search and Seizure from DEFCON 18, I discovered that only a subpoena is required to get your data from an online provider while a court-approved warrant is needed to search your personal machines. CrashPlan claim to use file and network encryption to protect your data on their servers, but I'd much rather roll my own backup servers for the added security.

After installing the CrashPlan proprietary Java client I fired up Wireshark to see how much CrashPlan was phoning home for local backups. When you open the program, you're forced to create an account with their online service, so naturally it sends that info. I was surprised though when I started configuring local backup settings and that information was sent to their servers too. Why do they need all your configuration? To populate their web interface.

This web interface could be useful for users wanting to change their settings remotely, but I'm not pleased with all my backup selections, destination folders, exclude lists, and the like forwarded on to their service and configurable there. It would be easy for them to store a lot more information about the files on the machine without the end user knowing.

CrashPlan seems to provide a good service for users wanting to do online backup, but one of their main selling points is the free local backup system. I'd be much happier with it if they gave an option to switch the web interface and all phoning home off. As it is, I'll stick with my harder to set up but open source and private BackupPC system.

### LaTeX Error: Undefined Color when using apa.cls

I was writing a journal article in LaTeX using the apa.cls style and was having trouble with my little command for leaving notes to myself:
\documentclass[jou]{apa}\usepackage{color}...\definecolor{Orange}{rgb}{1,0.5,0}\newcommand{\todo}[1]{\textsf{\textcolor{Orange}{[#1]}}}
On building, I'd get an error message: LaTeX Error: Undefined Color ORANGE'. It only happened when using the jou option, not with man or doc. I couldn't for the life of me figure it out, and on a whim changed the color from Orange to ORANGE. Viola! It works perfectly! Apparently something in there automatically upper-cases the color.
\definecolor{ORANGE}{rgb}{1,0.5,0}%Lowercase breaks on \documentclass[jou]{apa}!\newcommand{\todo}[1]{\textsf{\textcolor{ORANGE}{[#1]}}}`
