Personal data

There is a very limited number of companies that you can trust your personal information to. Things like name, surname, social security numbers, photos, home address, phone number, etc. I recommend against doing that at all.

Explanation of what personal information means to google can be found in their FAQ. I’ve found this info curious:

Types of information we might remove include:

National identification numbers like U.S. Social Security Numbers

Bank account numbers

Credit card numbers

Images of signatures

Types of information we will not remove include:

A user’s date of birth

A user’s address

A user’s telephone number

Google also doesn’t remove your pictures from the web search. Beware!

In other news – Citrix decided it’s a great idea to update/upgrade their forums. They’ve copy pasted personal information (name/surname) from your main account to the discussion boards. Currently it’s not possible to remove that, even if you adjust the information on the main Citrix account management web site. This is a good life lesson.

In other news – the same applies to real world when some companies sell their databases of personal info and you get haunted by phone calls/spam mails, etc. There’s a Latvian agency that is suppose to protect that kind of information and prevent it being used by 3rd parties without a consent. I don’t expect much from them as the fines for misuse of personal information are hilarious. Somewhere @ 100$ administrative fine. Cheapest marketing option available.

In other news – just when I wanted to buy myself an LG TV – it turns out they’re stealing end users’ personal data and selling it to advertisers. Not buying any of their products. Wireshark proof.

1Y0-300 Exam XenDesktop 7 Prep Guide

Citrix decided to revamp it’s certification paths, which is expected and pretty typical in certification business: keep people stressed, rename exams, update exams to reflect newer product version. etc.

Prove it. Again.

  

Having a CCEE certification, Citrix is suggesting the following: “CCEE for Virtualization certificants can achieve the Citrix Certified Professional (CCP-AD) by passing the Professional-level exam, 1Y0-300.”

 

At the time of writing this the information available on the internet is pretty vague. I will be sharing the information I’ve found useful for preparing for this exam. I’ve jumped right ahead to 7.1, as the changes are minor.

Official prep guide for the 1Y0-300 (Deploying Citrix XenDesktop 7 Solutions). Standard citrix prep guide, the links to multiple KB articles are useful. There are even sample questions available.

Introduction to Citrix XenDesktop 7 and Citrix Certification – cbtnuggets. Great value.

 

Field notes:

1) The most annoying things is (once again) XenServer hypervisor compatibility with Hyper-V Role. I know installing a hypervisor on a hypervisor is not a supported scenario (surprisingly), but it does work for VMWare Workstation which generally has better compatibility and in LAB environments there’s no other way to go around it if you want to properly practice XenDesktop.

XenServer 6.0.2 works on Hyper-V in Win8 out of the box. Although there still were some issues which prevented me from using the full functionality, so I went with VMWare as my final choice. 

XenServer 6.2.0 doesn’t (by default) hangs on “Detecting hardware”, disabling ACPI detection helps (“/boot/xen.gz no-real-mode acpi=off watchdog com1=115200.8n1 console=com1,tty”). Then the installation drags on to 55% and freezes. I scrapped the idea of using XS 6.2.

2) One additional disappointment was that App-V 5.0 does not work with SQL Express (Totally forgot that one! The Installler does not recognize an SQL Express instance, maybe there’s a way to “hack” the installation to skip some of the checks, but I haven’t played around with it that long). It clearly says so in this technet article:

Microsoft Windows Server 2008 (Standard, Enterprise, Datacenter, or Web Server)

R2

SP1 and higher

64-bit

Microsoft Windows Server 2012 (Standard, Datacenter)

   

64-bit

This is quite a horrible gesture from MS with no logical explanation.

Another horrible thing is excluding c++ redist from the App-V installation media.

3) Published resource keyword descriptions. KEYWORDS:Auto, KEYWORDS:Featured, KEYWORDS:prefer=””

 

To be updated.

Consumed RAM not being displayed in Windows 8

Recently ran into an issue when my PC with 16 Gbs of memory started using about 10Gb without any virtual machines running.

Task Manager and Process Explorer¬†both showed decent consumption numbers that didn’t go out of norm, this got me curious, because about 5-6 Gbs were missing.

I remember another awesome sysinternals utility – RAMMap:

“Have you ever wondered exactly how Windows is assigning physical memory, how much file data is cached in RAM, or how much RAM is used by the kernel and device drivers? RAMMap makes answering those questions easy.”

rammap

I’ve been rather surprised by this and instantly remembered I had custom settings for the size and auditing for my windows security log. So turns out windows security log uses memory mapped file. Humanity prevails once again!
