How to spent two days if you know nothing about Python:

• need parse HTML page code, where VK id and username of every person who shared post stores

with open('test.html', 'r', encoding='utf-8') as content_file:
    read_data = content_file.read()

from html.parser import HTMLParser
import re

class MyHTMLParser(HTMLParser):
    def handle_starttag(self, tag, attrs):
        vk_id = str(attrs)
        for line in vk_id:
            vk = re.findall('/\S+$', vk_id)
        vk_fnd = str(vk)
        if re.search('/\w+\'\)\]', vk_fnd):
            global vk_read
            vk_read = vk_fnd
            for ch in ['/', ')', '[', ']', '"', "'"]:
                if ch in vk_read:
                    vk_read = vk_read.replace(ch, "")
    def handle_data(self, data):
        global vk_name
        vk_name = str(data)
        assert isinstance(data, object)
        for line in vk_name:
            if re.match('\S+\s+\S+$', vk_name):
                print("@{0} - {1}".format(vk_read, vk_name))
                break


parser = MyHTMLParser()
parser.feed(read_data)

Now I know more. First bug and first fix: UnicodeEncodeError: 'charmap' codec can't encode character '\u0406' in position 15: character maps to <undefined>

How to install Python 2.7.6 on CentOS 6.3 (6.2 and 6.4 okay too, probably others)

stolen from Daniel Eriksson. Thanks Daniel! http://toomuchdata.com/2012/06/25/how-to-install-python-2-7-3-on-centos-6-2/ (modified a little) CentOS 6.2 ships with Python 2.6.6 and depends on that specific version. Be careful not to replace it or bad things will happen. If you need access to a newer version of Python you must compile it yourself and install it side-by-side with the system version. Here are the steps necessary to install Python 2.7.6. Execute all the commands below as root. Either log in as root temporarily or use sudo.

Install development tools

In order to compile Python you must first install the development tools:

yum groupinstall "Development tools"

You also need a few extra libs installed before compiling Python or else you will run into problems later when trying to install various packages:

yum install zlib-devel
yum install bzip2-devel …

Redmine Update

Great, there is a new Redmine 3.0.1 published!

• Changelog: http://www.redmine.org/projects/redmine/wiki/Changelog
• How to update: http://www.trianglesis.org.ua/update-redmine-2-6 (RU)
• Difficulties: http://www.trianglesis.org.ua/update-redmine-2-5-2
• Bad Update https://www.redmine.org/boards/2/topics/46141?r=46253

[su_note]Note! Redmine 3.0.1 has A LOT of unsupported plugins from old versions! Better remove them all and update it without plugins and than move back one by one.[/su_note] Some plugins can produce error like: [su_spoiler title="rake generate_secret_token"]

So, what can I say before migration? The first day looks good, nothing leaks, all services work as expected, and have some additional configuration for MAC addresses etc. During migration, I accidentally lost one system disk for one of my VM and photos backup disks, but this is not an issue, because all important stuff has more than one backup.

• The first expression about Hyper-V - it's more thrifty to system resources, I'm still tuning it to make my vms run smoothly but this is the first thing I saw.
• Then, Hyper-V has a good mgmt console for all my needs, I have a small env. so I do not need a HUGE MGMT-VM to host vCenterServer because of the new VM ver. cannot be managed just from preinstalled vC-client.
• Linux Vms such as Centos 6, Debian etc look good and running happily, the only change I've made - …

Required:

• http://www.eastern.nl/2014/12/mounting-vmfs-centos-7/
• http://www.tecmint.com/how-to-enable-epel-repository-for-rhel-centos-6-5/

Above May not work. So make a VMplayer VM with ESXi installation and mound physical disk where VMFS present. http://www.empirion.co.uk/vmware/vmware-vsphere-client-direct-download-links/ This is the biggest technical perversion I've ever did: There are:

• VmWare
  • Vmplayer + ESXi
  • mounted IDE disks with VMFS
  • bridged network
  • vSphereClient
  • added datastores
  • added NFS datastore to host where vmplayer runs (thought it were faster then just download)
• Windows Server 2012
  • NFS role and share
  • enought space

Bad method. Spent to much time. [su_box title="Warning IMHO!" box_color="#e4b7b7"]Send to the furnace all other ways to download vmdk from vmfs disks at EESXi, do it this way:[/su_box]

• On the host where you installed Windows 2012 (for example) and where HDD with ESXI disks is mounted install one of this
  • Hyper-V role
  • vmware player

[su_note]I assume you're smart enought to not install OS on the same disk where ESXi host kept it's filesystem?[/su_note]

• Then create new virtual machine …

When reading a lot of guides how better migrate from ESXi to Hyper-V I've saw some madness and then I become mad too. I decided to copy important VMs, which I don't want to break, on my laptop. YEAH!   Guess what? I bet when I'll migrate almost VMs to Hyper-V one last VM wouldn't convert and I will run it under the VMbox with bridged NIC from Windows Server with Hyper-V. I feel it would be exactly like that!

Very useful, much informative, wow!   http://www.virtualizationmatrix.com/matrix.php?category_search=all&free_based=1

So! This time has come! I will switch my virtual enviroment from Vmware to Windows Server 2012 + Hyper-v. I'm tired because of ESXi leak of RAM and CPU and unaviability to check a lot of health statements of my tower. If you are interested in this, grab y'r popcorn and check my tag "VMvsHyperV" in blog to watch my struggle! Let the battle begins!   Useful stuff:
