Hacker Labs Blacks in Computer and IT

n-RESEARCH-COMPUTER-628x314Yes, Black People are in Information Technology (I.T.). the world.

I have always had an interest in Computers

I am a person of color at am a Systems/Network Administration, current working for Vulcans Logic Networks Enterprise, Inc.

This Website is focused on learning about computers, computer systems, and networks, as well as a computer system and network security. This website and blog is a place for me to post my notes, research, and tips for Information technology, computer programming, computer operations, computer science and hacking; and anything else technology related blog. It only to provide help and information.

37300399_10100557956364723_7028654670700609536_nI have been working in I.T. for 15 years and I don’t know everything. Like martial arts (I am also a Martial Artist), your skills as a Systems & Network only get better over time and with content practice and training. This is about the art and training of the I.T. Professional.

I recently started working for a friend part-time, who uses best practices in his IT management services business, the month has been a reminder of what I learned when I got into the IT industry and it has also been an eye-opener to how lazy I have gotten over the last 13 years, because I have been working for people who were doing things wrong.

This website and blog are about me retraining myself and the continued growth in the area of computer systems and networks.

Otaku IT Computer Guy!

My Favorite Windows Server DNS, Forwarders Tab Config.

Recently, I have seen this a lot in windows environments; my follow windows admins try to solution DNS issues by putting their domain controllers in the environment in the forwarders tab.

The forwarders tab is for non-authoritative requests or queries for external addresses. Now in truth, I am simplifying this article. This really about a very basic domain or domains.

The are many types of forwarders, this config is just external DNS look-up. When end-users generally talk about the internet being slow, it is usually base the DNS servers by the ISP is slow and overload with a request.

This is the config I use for my dc’s forwarders in AD has saved a lot of headaches and complains about slow internet.

 I hope it is helpful.

4.2.2.1
4.2.2.2
4.2.2.3
4.2.2.2
8.8.8.8
8.8.4.4

Forwarders should only really be used for external DNS lookup and if the root server is an unavailable and/or non-authoritative request.

I will do another article about network congestion.

Error opening attachments / Cleaning out the Temporary Outlook Files folder

I did write this article but it is the best article to write about this common problem.

————————————————————————————————————————–
When opening an attachment directly from within Outlook you could get an error message saying that it can’t create the file and to that, you need to check the permissions on the folder you want to save it in. In most cases, the permissions on the folder aren’t the issue but the fact that the folder is “full”. When you open an attachment directly from within Outlook it will first save a copy to a subfolder of the Temporary Internet Files folder.

Cleaning out the folder will solve the issue.


Outlook Secure Temp folder

Unfortunately, this is easier said than done. The subfolder name Outlook creates (on the installation of Outlook) in the Temporary Internet Files folder is quite random.
In Outlook 2003 and previous, the name starts with OLK and is followed by up to 4 random numbers or letters. In Outlook 2007, 2010 and 2013, this folder is called Content. Outlook and then has a subfolder which is named with 8 random numbers and letters.
In addition, by default, you cannot simply browse to the folder to clean it out. Getting to the Temporary Outlook Folder can still be accomplished in 2 easy steps though.
Step 1: Locate the folder
The folder location is stored in the registry in the following key;
Outlook 97 HKEY_CURRENT_USER\Software\Microsoft\Office\8.0\Outlook\Security
Outlook 98 HKEY_CURRENT_USER\Software\Microsoft\Office\8.5\Outlook\Security
Outlook 2000 HKEY_CURRENT_USER\Software\Microsoft\Office\9.0\Outlook\Security
Outlook 2002/XP HKEY_CURRENT_USER\Software\Microsoft\Office\10.0\Outlook\Security
Outlook 2003 HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Outlook\Security
Outlook 2007 HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\Security
Outlook 2010 HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\Security
Outlook 2013 HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Outlook\Security
Step 2: Get to the folder
  1. Open the OutlookSecureTempFolder registry key from the location provided in Step 1.
  2. Copy the path from the key.
  3. Open Explorer
  4. Paste the address in the Address Bar and press Enter

Use OutlookTools or OutlookTempCleaner

Still not easy enough or just don’t want to go in the Registry to find the folder location? I’ve created two free tools which can do the trick as well.
OutlookTools offers besides locating, opening and cleaning up the SecureTempFolder also quite a lot of additional features to troubleshoot and tweak Outlook.
OutlookTempCleaner focuses only on dealing with the SecureTempFolder and can also be used in (corporate) login and logoff scripts to clean up the folder without any end-user interaction.
OutlookTempCleaner
OutlookTempCleaner can detect and empty Outlook’s Secure Temp folder automatically for you.

Check out this phone-controlled robot from a Twilio/Node.js hacker

Nice!!!  Check out this phone-controlled robot from a Twilio/Node.js hacker
July 3, 2012, 11:50 AM


 

We just about overloaded on developer buzzwords there, so let’s back it up a bit.
The bot was built by Twilio developer evangelist Jonathan Gottfried, to whom we say, nice work, Jon! There’s no quicker way to developers’ hearts than showing them how to build and code a robot, and no better way to evangelize for your company’s software than by using it in a said robot in an actually interesting way. Twilio overlords, give this man a raise!
“Robots have fascinated me for as long as I can remember,” writes Gottfried on the company blog. He then proceeds to go into great, and we mean great, detail on how the bot was made “using Twilio, Arduino, Node.js, and the RN-XV WiFly module.”
The result is a robot you can control from your phone’s keypad. The post includes step-by-step images and lots of code snippets.
You might be asking, “Why, why in heaven’s name, would anyone use Node for such a task?” The Hacker News army asked the same thing, to which Gottfried replied, “It was the easiest way I found to set up a simultaneous HTTP server and TCP socket to the bot.”
In the HN thread, Gottfried also said, “The hardest part for me was getting the Wi-Fi module to work,” and, “It’s pretty fun to play with, honestly. Hasn’t tried to kill me yet….”
