Circuit Simulator Applet - falstad.com
Feb 23 at 2:02pm by crackmac
This is a very cool little app that I found after listening to Security Now Episode 233: Let’s Design a Computer. Some of the basic circuits were hard to visualize and this app kind of brings them to life with animated current flow and some interactivity. For the podcast you’ll want to look in the Circuits menu for the Logic Families/RTL for the circuits being discussed.
Get Vista and Samba to work - Code Monkey Business AU
Feb 11 at 5:05pm by crackmac
I used these instructions to get my Windows 7 clients to connect to my Mac 10.4 server.
——————–
Early adopters of Microsoft’s new Vista operating system may notice that it will not connect to Samba share folders out of the box. This will be a bit of a pain for many enterprise customers. The technical reason is because Microsoft Vista’s default security policy is to only use NTLMv2 authentication. According to a Google search Samba doesn’t support this yet.
Update: Some readers have pointed out that NTLMv2 authentication is supported in Samba 3.0. However, this certainly wasn’t an option to get this running in my instance.
To get Vista to work with Samba follow the simple instructions

iPhone Wifi not working? Reset your network settings | A Mountain Top, LLC

iPhone Wifi not working? Reset your network settings | A Mountain Top, LLC.
From the Home Screen, I clicked on “Settings”. From there, I scrolled down to “General” and clicked on it. From there, I scrolled to the bottom, clicked “Reset”, then “Reset Network Settings”. After accepting the warning that I was doing something dangerous and clicking the giant red button, the iPhone started buzzing and shaking and generally throwing a fit. After it was done getting reset, I simply went back into Settings -> Wifi, saw my network, connected and it worked!

Google PowerMeter

Google PowerMeter
Google PowerMeter is a free electricity usage monitoring tool that provides you with information on how much energy your home is consuming. Google PowerMeter receives information from utility smart meters and in-home energy management devices and visualizes this information for you on iGoogle (your personalized Google homepage). And, Google PowerMeter is free.
Studies show that being able to see your electricity usage in near real time, throughout the day, makes it easier to reduce it and save money. This sort of feedback requires either an advanced electricity meter, a “smart meter,” or a consumer-owned electricity management device, and many of today’s smart meters don’t display information to the consumer. Consumers should have access to data on their personal electricity use, control who gets to see this data and choose from a range of services to help them understand and benefit from this data. We’re working with federal and state governments to ensure our energy policies encourage consumer information; read our comments to the Department of Energy on smart grid investment in the stimulus, Edward Lu’s testimony to the Senate Committee on Energy and Natural Resources, and our comments to the California Public Utilities Commission and our joint statement with leading companies and NGOs. We hope that consumers will soon be empowered with an entire ecosystem of energy information products and services.
Google PowerMeter is a project of Google.org, Google’s philanthropic arm, which aspires to leverage the power of information and technology to address global challenges.
Mac OS 10.5.7 update broke JMeter
Aug 3 at 5:05pm by crackmac
The latest Java update from Apple broke JMeter… not sure why but JMeter needs Java 1.5. Add this line near the top of your jakarta-jmeter-2.X.X/bin/jmeter file using your handy dandy text editor. I like TextWrangler.
JAVA_HOME="/System/Library/Frameworks/JavaVM.framework/Versions/1.5"
If you use any of the other jmeter run scripts you may need to add this to them as well.

If you are developing an application for Linux desktop and would like to automatically find out more information about system, use the following commands in shell scripts to gather information about system. Recently I was involved in project where I need to collect information about running GUI, browser and other information such as disk space, running kernel etc.

How to flush DNS Cache on Mac OS 10.5
Feb 9 at 11:11am by crackmac
Finally a way to flush the DNS cache on Mac OS 10.5 “dscacheutil -flushcache“. PC users have always had a way to do this with “ipconfig /flushdns” but Mac users usually had to restart. In Mac OS 10.4 there was “lookupd -flushcache” but that never quite worked 100% of the time. Here’s a bit of the MAN page and a link to the complete page via developer.apple.com.
dscacheutil — gather information, statistics and initiate queries to the Directory Service cache.
SYNOPSIS
dscacheutil -h dscacheutil -q category [-a key value]
dscacheutil -cachedump [-buckets] [-entries [category]]
dscacheutil -configuration dscacheutil -flushcache
dscacheutil -statistics
DESCRIPTION
dscacheutil does various operations against the Directory Service cache including gathering statistics, initiating lookups, inspection, cache flush, etc. This tool replaces most of the functionality of the lookupd tool previously available in the OS.
