Changing the Screenshot Location in OS X

Each user in Mac OS X can customize the location that their screenshots (aka screencaptures) will go. To do so you would edit the com.apple.screencapture property list, customizing the location key. You can easily edit this file using the defaults command. For example, if we wanted to set the location to go to a folder called screenshots in the home directory of a user we could use the following command:

defaults write com.apple.screencapture location ~/screenshots

You can also change the default type of screenshot which I cover here http://krypted.com/mac-os-x/mac-os-x-changing-the-default-screen-shot-format.

Malware: The PC Users Worse Enemy

I originally posted this at http://www.318.com/TechJournal

How to Know You Have it and What to do About Removing It

What is it? Malware, short for Malicious software, is the macro concept behind names like “Adware”, “Spyware”, “Hijackers”, “Toolbars” and “Dialers”. Malware is a growing PC-related assault epidemic (doesn’t effect Macintosh too much yet).

How you get it? Malware tends to sneak into your life (usually in a hidden or invisible manner) via third party software (software from less-than well known developers) disguised as added functionality to your work flow and your internet experience (and other bells and whistles) in order to execute many malicious tasks that are bad for business.

Tell tail signs you have it- there’s the activity you can see; Pop-up ads, re-directing of your browser, out-of-the-ordinary sluggishness, and other virus-like activity. Then there’s the activity you can’t see (and generally the most malicious of all); The taking of personal information from different parts of your PC, keeping track of web sites you visit and web searches you make, files you download, software you install.

All of this can (and usually does) involve your personal and sometimes private information, cause system slow down or even interruption inproductivity and produce virus-like activity to the point of annoyance or even system crash. This involves security issues, downtime and productivity loss (money lost!)

Discovering you are one of malware’s victims is critical and yet only half the battle. Knowing what steps to take to rid your life of it (and possibly to prevent future attacks) is then key. The point is, malware is bad and Three18 can help you get rid of it.

At Three18 we continue to stay on top of current malware and other emerging malicious technologies and we pride ourselves on educating our clientele on the benefits of using practical skeptical computing technique to reduce the possibility of malware ever getting to your system and/or network.

If you do get malware’d, Three18 will help to get you and your network cleaned up and safely back onto the information super highway!

Creating a crontab

Creating your first crontab job is a three-part process:

  • Prepare the absolute path to the program or script that you want to run
  • Create a text file containing a line to schedule the job as described above for crontab fields
  • Upload the text file to your system cron

When preparing program to run or creating scripts to run remember that crontab jobs are background tasks. There is no terminal attached to a crontab job so there should be no print statements that normally write to the screen. (It is possible to redirect such print statements.) The same consideration hold true for requesting user input.

Let’s assume that we want to run this script:

/Library/WebServer/cgi-bin/parselogs.cgi

Next create a file to hold your crontab instructions. Let’s call it “cron.txt”. Let’s also have our script execute at zero minute every hour. Put the following crontab command line in the text file “cron.txt” and save this file as a text file: 0 * * * * /Library/WebServer/cgi-bin/parselogs.cgi

The last step is uploading the contents of your “cron.txt” file to the system crontab spool area. Enter the following at the system prompt.

crontab charles.txt

If you would like additional detailed information on crontab, enter the following at your bash prompt:

man crontab

Setting Compatibility Mode for Windows Applications

Some applications need a little help to run. If it’s an older application and it will not launch then think about changing the compatibility mode. In order to do so, right-click on the application and click on the Compatibility tab. From here, set the compatibility mode to a previous version of Windows and then try to fire it up. Might just help…

NetFlix Now Online

OK, so NetFlix was always online, but did you know that you can watch movies online too. Not all, but chances are, if you have enough movies in your queue that you’ll have at least one that is able to be watched online. The technology that allows all of this is Microsoft’s Silverlight. Because Silverlight is not yet available for the Mac you can’t watch NetFlix online from a Mac just yet. Rumor has it that Silverlight will be available soon though, so just be patient and it’ll get there…

Another aspect of NetFlix that is often overlooked is social networking. You can rate movies and then share your queue and your ratings with those who you connect with. This makes watching movies at home a bit more of a social experience for those of us with anti-social tendencies.

Application Acceleration in Windows XP

In Windows you can choose to speed up or slow down an application by assigning a priority to the application, which prioritizes the amount of resources that can be had by that application. In order to set the priority, bring up the Task Manager in Windows. Then click on the application in question, Right-Click on it and then choose the Set Priority sub-menu and assign the application with the appropriate priority.
