McAfee fails to secure!

Up to couple of weeks ago I have always used Symantec for my antivirus software. But in the last two weeks I decided to try McAfee AntiVirus, which comes as part/component of the McAfee SecurityCenter and provided for free to Comcast subscribers. So, I installed it on some of the machines I have at home.

A side note about my home network. I have couple of mid-towers, couple of laptops and a server. I use VNC to remote into the machines. For those of you who do not know what VNC is. It is an application used to remotely view the screen of another computer and have full control of it, almost as if you were there. I say almost, because the user has only software control and is not able to do anything physical to the machine, like a hard reboot for example. Hens “remote” :).

Back to McAfee. McAfee AntiVirus has a security feature called PUP – Potentially Unwanted Program. On each box I installed the antivirus, VNC was recognized as a PUP shortly after the installation was completed. Now, one would only expect that if the antivirus software recognized an application as potentially harmful to the user it will quarantine the application and disable its ability to interact with the computer until further action from the user. Well, it did NOT!

I was able to set McAfee to trust VNC through VNC. In other words, if I was an attacker I would have been able to set the antivirus software to trust my invasive program and I would have maintained my control of the victim's computer.

McAfee SecurityCenter – secure ... uhhhhh ..... only on the out side.

I suppose McAfee's excuse would be - “well you did not install other components of the SecurityCenter. Like for example the McAfee Firewall.” Oh yeah? Well, if that's the case why do you even have a feature like PUP in your antivirus software? Response: “uhhh ... sell more of our software products?! Hopefully.”

Format MAC Address [JavaScript]

I am currently working on a project which will allow users to register their Wi-Fi enabled, non-web browser enabled, devices on the network. These are devices like printers, Apple TV, and Xbox*. One of the data points that have to be collected from the user is the device MAC address. The project customer wants that address to be properly formatted when they see it in the support ticket.

We have several options. We can format the address either on the back-end after the form has been submitted. Or we can format it on the front end via a separate text field for each character pair, but that is too many fields to handle. A better solution is to use a single field and format the user input at the time of input or upon submit. In those cases, the former is better because the data will already be formatted when the overall form input is being validation after the user clicks the “Submit” button.

We are going to format the user input as it is being provided, thus having proper data when vali…

How to setup Coda 2 to push to GitHub?

Setting up a new site in Coda 2 and cloning a GitHub remote repository is not that big of a deal. Where you will most likely run into problems is when you try to push your changes to the GitHub remote repository. Below I will show you how to update the Git config file in your local repository so you do not run into one of the following errors:
git push failed remote: Remote anonymous access to repository deniedgit push origin master Username: fatal: Could not read passwordThe GitHub repository address I am going to use is that of Source Code DNA: I will assume that you have already setup your Coda 2 site profile and cloned your repository, you have made some changes, and now you are ready to push those changes to your projects GitHub repo.

SNOOZ: Sound. Sleep.

I was on the Snooz Kickstarter page today, revisiting the project’s details and timeline progress. The device, which is a white-noise generating machine, recently became available for pre-order. Snooz is meant to be an alternative to having a TV or a stationary fan running at bed time. In my case, I bought it for my wife so we can get the TV out of the bedroom.

Whilst on the comments page I read the following comment, posted recently by Ken Tran:

I'm not a fan of the new fabric design. ...
I must disagree. If you take a look at the original design, which is all plastic and no style, I must say it is fugly. It is all utilitarian - not something I rally want to look at or see when I walk into the room. The final design, seen on the right, is something that beacons to be explored, looked at, utilized.

I am a big fan of Bang & Olufsen. They use fabric from Kvadrat in their line of products. Incorporating soft materials like fabric or leather in something which is meant to be place…
