George Will: Trump has a point about rigged elections

Exceptionally perceptive summary by George Will concerning how the Democrats underhandedly work to "tilt" the election in their favor.
-------------------------------------

Since originally posted, I ran across Project Veritas that supposedly documents Democratic dirty tricks. Below are the links to the video.

Rigging the Election - Video I: Clinton Campaign and DNC Incite Violence at Trump Rallies.

Rigging the Election - Video II: Mass Voter Fraud

I'll leave it up to you to contemplate the truthfulness of the Project Veritas videos.

 Another relevant article has since surfaced.


The Washington Times writes: "Those supposedly spontaneous protesters disrupting events for Republican presidential nominee Donald Trump actually may be professionals trained by operatives working with the Democratic National Committee and the Hillary Clinton campaign.

A yearlong undercover investigation by the conservative group Project Veritas Action shows Democratic strategists discussing how they hire agitators — including union members, homeless people and the mentally ill — to incite violence by provoking Trump supporters on camera at campaign stops."

The Washington Times has issued an updated article:



 According to the Times: "Two top Democratic strategists have exited the presidential campaign after explosive undercover videos showed them discussing voter fraud and their roles in planting paid agitators at campaign events for Republican candidate Donald Trump."

Well at this stage of the election process the resignation of any staff for bad behavior is pretty much meaningless. The damage has already been done and can't be undone by November 8, 2016, election day.

Again, any readers to this post are encouraged to do their own research on this apparent attempt to sabotage the election process by the Democratic party.
 -------------------------------------

Another update (10/31/2016). Evidently a Democratic operative has been feeding Hillary questions prior to her debates. Donna Brazile out at CNN after WikiLeaks reveals she leaked more debate questions to Clinton.  Seems that Hillary's unethical behavior is slowly being unmasked to the public.

Create Logical "Home" Volume When Using Logical Volume Management (VLM)

1. Getting Started. Introductory Material.

This guide assumes that logical volumes have been installed and that there is no volume dedicated to the “home” directory. The process for establishing a “home” directory using partitions is described in Ubuntu documentation Partitioning/Home/Moving. The process for using logical volumes is similar, but involves a substantially different process. Reading the Ubuntu documentation before beginning will be beneficial.

The nature of logical volume management (LVM) is described here. What is LVM

The following document is being referenced for informational purposes: HowTo: Set up Ubuntu Desktop with LVM Partitions

This tutorial was based on using Ubuntu 16.04.

2. Preliminary Step. Determine Volume Allocations.


Determine the amount of space that needs to be dedicated to the operating system (root) and the amount of space that should be allocated to “home”. Essentially the process you will be following will involve splitting the “root” volume into two volumes. One volume will remain "root" and a new volume “newhome” will be created. In the table below, “root” has an allocation of 915G. Fifteen Gigabytes of data have been installed of which 4.3G occurs within the “home” directory.

Size of the Hard Disk - 1000G
Applicable Volume
Current Allocation (Usage)
Proposed Allocation
Partition1 (Boot)
0.255
0.255
Root
915 (15)
100
Home
0 (4.3)
815
Swap
16
16
Total (approx)
931
931


Obtain your logical volume group name and volume name by using the Logical VolumeManagement application. This application is available through the Ubuntu Software Center by entering "LVM". This information is also available through the terminal by issuing the command "sudo lvdisplay" In this example the logical group name is: “ubuntu-vg”. The logical volume name is “root”.


Backup your computer before going further!


3. Early Steps.

Boot the computer from a live CD.
The “root” volume must be unmounted.

Before attempting to use “apt-get” to download packages run “apt-get update” to get the software list updated should downloading be necessary.

Below are two reference resources that I relied on. Please note that the syntax used in some of the examples provided may not be available in Ubuntu.

Redhat LVMConfiguration Examples

ArchLinux Wiki: LVM


4. Reduce the size of both the root volume and root file system.

Approach #1. The preferred approach.
a. Run:lvresize -L 100G -r ubuntu-vg/root 

Approach #2.
a. Run: “e2fsck-f /dev/ubuntu-vg/root”.
b. Run: “resize2fs /dev/ubuntu-vg/root 70G
c. Run: “lvresize -L 100G ubuntu-vg/root
d. Run: “Run “resize2fs /dev/ubuntu-vg/root

Notes: Apparently I did something wrong when using “lvresize” since it would not recognize the “-r” option. Consequently,  I used Approach #2. Use Approach #1 if you can.

ArchLinuxWiki examples for reducing the size of the volume and file system.

5. Create new volume and establish file system.

a. Run: "lvcreate -l 100%FREE ubuntu-vg -n newhome /dev/sda5
b. Run: "mkfs.ext4 /dev/mapper/ubuntu--vg-newhome"  
ArchLinux Wiki example for creating a volume.

To view the results of the preceding operations use: "lvdisplay"


6. Modify the "fstab" file to mount "newhome" under /media/home


Modify the  /etc/fstab file to add the lines:

# Logical volume for home
/dev/mapper/ubuntu--vg-newhome /media/home        ext4         errors=remount-ro       0       2

This can be done before you re-boot or after you reboot into normal operation. From this point on you can follow the prior Ubuntu documentation on creating a home partition stating with the section: "Copy /home to the New Partition".


7. Copy home into the new /media/home volume.

a. Run: "sudo rsync -aXS --exclude='/*/.gvfs' /home/. /media/home/. "



8. Modify the "fstab" file to mount "newhome" under /home.


# Logical volume for home
/dev/mapper/ubuntu--vg-newhome /home ext4 errors=remount-ro 0 2

Don't reboot.


9. Save "old" home by copying to "old_home"  and creating empty home folder.

 

a. Run: "cd / && sudo mv /home /old_home && sudo mkdir /home"

OK to reboot. 

Final Notes: I did this once and kept the notes you see above, I will not claim to be any sort of expert. Evidently, importing the text from LibreOffice wasn't helpful in terms of formatting this web-page. Please let me know if there are any correction and/or modifications that would benefit future readers.

The Multi-Year Science Fiction Magazine Database Extravaganza Endlessly Continues II

Screen shot of the revised main page on my testing version. As much as I hated to do so, I removed the Galaxy cover graphic as being too distracting. Now I have a lot more "real estate"  for displaying a magazine's data. I will continue to display the Galaxy cover as the opportunity arises and where it will fit-in.


Other enhancements, from the prior version:
  1. Edit issue and story data directly from the interface.
  2. Edit the names of the story author and the cover artist from the interface.
  3. Add the names of new authors and new cover artists from the interface.
  4. Add missing stories to an issue from the interface.
Previously, to edit and/or add certain data such as those identified above, had to be done through phpMyAdmin.

The Fallacy and Idiocy of the so-called "Golden Key" to Break Encryption

The recent terrorist attacks in Paris (France) and San Bernardino (California) have invigorated the demands of clueless politicians for the creation of a so-called "Golden Key" that would allow law enforcement to decrypt encrypted communications.  In a recent Washington Post Article: After terrorist attacks, the debate over encryption gets new life; the Post notes that: "On Wednesday, Sen. Dianne Feinstein (D-Calif.) became the latest senior lawmaker to call for such legislation. “If there is a conspiracy going on” among terrorist suspects using encrypted devices, “that encryption ought to be able to be pierced,” said Feinstein, vice chairman of the Senate Intelligence Committee."  In regards to another clueless politician, the Post wrote: Kasich doesn’t understand how the tech that keeps you safe online works.

The problem is that should a "Golden Key" actually be developed and implemented as demanded by the clueless politicians, the "bad" guys, such as the terrorists, will also be able to use the "Golden Key" to break the encryption of the "good" guys, thus making the communications of the "good" guys insecure. Fortunately, the Washington Post also ran the article: A key under the doormat isn’t safe. Neither is an encryption backdoor, which counters the assertion by Sen. Feinstein that "piercing" encryption would be helpful.

The mere existence of a "Golden Key" means that it can somehow be stolen or otherwise acquired by anyone. An unwritten law is that secrets leak. Once acquired by the "bad" guys, they will be able to break the encryption of the "good" guys. That means the "good" guys such as the banks may find themselves susceptible to hacking. Furthermore, as for the "bad" guys, why they will simply go to their Plan "B", the development of their own proprietary encryption. Thus the development and imposition of a "Golden Key" is a fools errand. To protect the "good" guys, unbreakable encryption is required.

The necessity for unbreakable encryption, even if it unfortunately means that the terrorists benefit, is a complex topic. For more details and greater insight, I will refer you to the TechDirt theme concerning encryption. Please read the posts of the people commenting on the various articles.  They will provide much more insight than I have provided.

A link to a variety of articles published in the Washington Post on the topic of encryption. As with the TechDirt article, it is also important to read the comments provided.

A link to an old, but still relevant, 1997 article from the Electronic Frontier Foundation: Decoding the Encryption Debate.

A post by Troy Hunt:  Security Sense: Encryption is a necessity that cannot feasibly be compromised.

Phil Muncaster writes: IT Body: 'Let’s Not Weaken Encryption in Wake of Terror Attacks'Mr. Muncaster quotes ITIC president and CEO Dean Garfield as saying:Weakening security with the aim of advancing security simply does not make sense.

The Multi-Year Science Fiction Magazine Database Extravaganza Endlessly Continues

I now have a rudimentary version of a Science Fiction Magazine Database that works through your (internet) browser. The benefit of this approach is that it works on your home computer and/or LAN, does not require specialized database software such as Base or MS Access, and (at some future point) will be internet ready. However, it does require that you have MySQL and Apache (LAMP/WAMP) operating on a computer. There is still much work to be done.


Opening Screen
The image above is the opening (main) screen.  From the opening screen one can do an author or story search. Additionally, one can display all magazine issues or filter by magazine.

Eventually, subsequent screens (as you can see below) will need to be redesigned to remove the Galaxy cover as it tends to be distracting in subsequent screens.

Note: The "Author" field contains a hyper-link. Clicking on it will display all stories written by that author.


Listing of Each Magazine Issue in the Database

My apologies to those reading other magazines. I have just been tracking Analog. The image below displays some of the F&SF magazines that have already been entered. Please be assured that this database can handle all magazines.

Note: The "Magazine Name" field contains a hyper-link. Clicking on it will display all stories for that particular issue.


Filtered Issue List

Selection of an Author


Display of all Stories Written by the Author Selected

Selection of a Magazine Issue

Display the Contents of the Selected Issue


Listing of All Stories Having "Pluto" in Their Title
Note: In the screen above there are hyper-links for both the author and magazine issue. Consequently, one can lookup either the author stories or the contents of the magazine issue.

This project still needs a lot of work. For example, I have not yet gotten around to developing editing screens. Turns out editing is much more complicated than simple data retrieval. Editing, when it is done, has been done through phpMyAdmin which works directly with MySQL.

Additionally, it seems that I will need to learn JavaScript for certain actions. Drat, yet another programming language to learn!!!

This project is essentially for my self edification. A more extensive and complete source of information is located at the Internet Speculative Fiction Database (ISFDB).

I anticipate that this browser based approach will be the final rendition in the development of this database. But then one should never say never. Eventually, I intend to complete it. But don't hold your breath.

Should you have any comments, please leave them.
