Book Review of “Cosmocopia”

“Cosmocopia” was published in 2014 and was written by Paul Di Filippo (http://paul-di-filippo.com/). This is Mr. Di Filippo’s third science fiction novel.

I obtained a galley of this novel for review through https://www.netgalley.com. I would categorize this novel as ‘R’ as there are Mature Situations. The novel is written in the third person and is set in the contemporary world as well as in an alternative dimension. The primary characters are Frank Lazorg and Crutchsup.

Frank is an artist that is in his final days. He has been successful, but now he is slowly recovering from a stroke. He has yet to pick up his brushes to paint again. He tries a drug to help him get back to his art, and he accidentally falls through an inter-dimensional crack.

Crutchsup is the female that finds Frank in the other dimension. She takes him under her wing and helps him adjust to his new world. Over time, they develop an unusual physical relationship.

This is the second book of Mr. Di Filippo’s that I have read, and it will probably be the last for me. The plot and characters were strange but OK. The story was all too weird for my tastes. I did spend a full four hours to complete reading the book, but I did not like it. I give this novel a 3 out of 5.

IEEE Rock Stars of Cyber security Event

IMG_0179I spent the day yesterday at the IEEE Rock Stars of Cyber Security event held in Austin, TX. It featured 7 notable speakers on Cyber Security, as well as a panel discussion.

I found the presentations to be very thought provoking. Computers are proliferating around us, yet we are having a difficult time protecting the data residing in those systems today. Action must be taken to strengthen the security barriers, and users must behave smarter if the data is to be protected.

Here are a few tidbits from the presentations:

  • All organizations need to pick a security framework and stick to it
  • Currently we are loosing the war on cyber attacks
  • By 2050 there are estimated to be 50 billion new devices making up the Internet of Things which will need to be protected
  • 90% of companies with 250 employees or more had malicious security events in 2012
  • Current security tools #1 job is preventing false positives
  • Biggest threat to cyber security is convenience
  • “You can’t patch stupid” – humans pose the largest vulnerability in computer security
  • Security = defense in depth
  • The top fear of the common man is that he will not be able to buy groceries or make other purchases without exposing his personal data
  • 56% of organizations have been the target of cyber attacks
  • 44% of breaches involved third party mistakes

The complete set of slides from the various presentations will soon be available on the IEEE web site.

Book Review of “Midnight fire”

“Midnight Fire” was published in 2012 and was written by Melody Anne (http://www.melodyanne.com). Ms. Anne has written almost 30 novels. Most are Romances or lean heavily in that direction.

I was alerted to this book being available for free through https://www.bookbub.com. This is a Young Adult Romantic Fantasy. The book is set in a near future and I would say it is ‘PG’. The book is written in the third person with the major characters being Phoenix Light and Jayden.

Phoenix is 11 when the world around her is suddenly thrown into war. Since then she, her family, and a few others have hidden in caves trying to survive. Phoenix is now 17 and is finding living in the caves difficult.

Jayden is a fallen angel who is sent bro cause the downfall of the group that Phoenix is living with, but he becomes attached to her and refuses to cause the group’s downfall.

Chastity is Jayden’s sister, and still an angel of the light. She tries to bring Jayden back from his fall into darkness. She meets and becomes attracted to John, Phoenix’s older brother.

A battle is going on between the forces of light and dark for the Earth. I was not a big fan of this book. The characters were OK, and the plot about what you would expect. I won’t be reading any other books in this series. Fortunately this one only took five hours to finish. I give this novel a 3 out of 5.

Book Review of “A Call to Duty”

“A Call to Duty” was published in 2014 and was written by David Weber (http://www.davidweber.net) and Timothy Zahn (http://en.wikipedia.org/wiki/Timothy_Zahn). This is the first book in the “Manticore Ascendant” series, which is a prequel to the “Honor Harrington” books. Mr. Weber has written more than 45 books and Mr. Zahn 25 books.

I obtained a galley of this novel for review through https://www.netgalley.com. This is a Science Fiction novel set in the far future. I would categorize this novel as ‘PG’ as there is some Mature Language. The novel is written in the third person, with the primary characters being Travis Long and his half brother Baron Gavin Winterfall.

Baron Winterfall is a young Lord, of very little importance. But then he is approached by some of the powerful members in Parliament to join them as they attempt to shut down, or at least significantly reduce the Royal Manticoran Navy. In part, Baron Winterfall was chosen because his half brother Travis has just joined the Navy.

Travis is drifting and is not sure where he wants to go. He wanders into a RMN recruiting station, which saves him from getting arrested when his ‘friends’ attempt to rob a jewelry store. Travis is a stickler for the rules, which causes him to rub many the wrong way. He does have a knack for thinking outside the box, which gets him noticed. Unfortunately, not all appreciate him for it.

I have been a reader of Davie Weber since 2011. After hearing Leo Laporte and Steve Gibson talk about the Honor Harrington series on the Security Now podcast (http://twit.tv/sn) I finally tried it. I have been hooked on the “Honorverse” and David weber ever since. This series is set many years prior to the time of Honor Harrington. The Royal Manticoran Navy is in shambles. This story begins the very long process of turning the Navy around. I thoroughly enjoyed the 11.5 hours I spent reading the novel. I give this novel a 4.5 (rounded up to 5) out of 5.

FOSS Under OS X: Calibre

I have been an avid reader for many years, and since getting an iPad
shortly after they were introduced in 2010, I have mostly been reading eBooks. A friend pointed out a really good FOSS application
Calibre – to manage those books that are not encumbered by DRM. I have found Calibre to be of great use.

Calibre is a Free and Open Source Software (FOSS) tool for managing your eBook library that came into being in 2006. Currently there are over 3.5 million active copies of Calibre in use. The features that it provides includes:

  • Library Management
  • E-book conversion
  • Syncing to e-book reader devices
  • Downloading news from the web and converting it into e-book
    form
  • Comprehensive e-book viewer
  • Content server for online access to your book collection
  • E-book editor for the major e-book formats

I run Calibre on my Mac Mini and I have begun to load Calibre with
all of my eBooks to make them more manageable. I can search my
library by author or genre, as well as keep track of which eBooks I
have not yet read. The program is available for Mac OS X, Windows
and Linux. If you have a large library of eBooks on your computer,
it may be something that you want to look into.

Book Review of “Nexus”

“Nexus” was published in 2013 and was written by Nicolas Wilson. Mr Wilson has written nine novels as well as some short stories. This is the first novel of “The Sontem Trilogy”.

I obtained a galley of this novel for review through https://www.netgalley.com. I would categorize this novel as ‘R’ as there is Mature Language, Mature Situations and Violence. The novel is written in the third person and is set in a far future where space exploration has just begun in ernest. The primary character is Anderson “Drew” Grant, with a little peak at Pete Ferguson’s point of view.

Drew is Captain of the starship Nexus, which is on a deep space mission for the Sontem company to explore and secure business contracts for the corporation. As they visit diverse planets they encounter friends, as well as enemies. The crew must deal with internal strife, corporate over site, and hostile aliens.

I spent about 10.5 hours reading this novel, and I had mixed feeling about it. I liked the plot from the stand point of a Star Trek like exploration. The down side is that Drew is constantly a wise ass, as is much of the rest of the crew. There was really too much of that for my taste.

I also found Drew to be a less than heroic, likable character. I would never place him as an officer on any vessel, and certainly not as the captain. I give this novel a 3 out of 5.

Book Review of “Steel Lilly”

“Steel Lilly” was published in 2013 and was written by Megan Curd (http://megancurd.com/). This is Ms. Curd’s fourth novel and the first in “The Periodic Series”.

“Steel Lilly” is a Young Adult Steampunk/Fantasy set in a post apocalypse Detroit, Michigan. I was alerted through http://daily.ereaderiq.com/ that the book was available for free. I would rate this book as ‘PG’ as there is a little violence. The novel is written in the first person and the major character is Avery Pike.

Avery is an Elementalist, that is, one who is able to exert some control over one of the elements. In Avery’s case, she can control water. This is important in her world as everything runs off of steam. The very survival of her home, Dome Four, depends upon steam for power. A world war has left the Earth in an unlivable state. The only survivors live under domes, and as far as the residents of Dome Four know, they are the only survivors.

But life in Dome Four is not a pleasant one. Avery has been alone for years since her parents disappeared. When Avery’s best friend Alice Dobson is being sought after by the Polatzi, Avery takes advantage of a strange boy’s offer and runs away with he and Alice. The boy, Jaxon Pierce, takes the girls in a strange machine to Dome Seven.

Supposedly, Dome Seven has a school for Elemantalists where she and Alice will be well treated, and she will learn how to control her ability. Avery soon finds though that the new Dome has it’s own set of secrets. One of those secrets concerns the location of her missing parents.

The novel took me about 5.5 hours to read. The premise that some people became “Elemantalists” after being exposed to radiation from bombs used in the war seems a little far fetched, but then this is a fantasy. The plot was not bad, and it kept me engaged with the story. I give this novel a 3.5 (rounded up to a 4) out of 5.

Book Review of “Schooled”

“Schooled” was published in 2012 and it was written by Christa Charter. Ms. Charter has written six novels, “Schooled” being the second. “Schooled” is also the first in her “Lexy Cooper Mystery” series.

I was alerted to “Schooled” being available for free download through http://www.moreforlessonline.com. This is a mystery set in contemporary Redmond, Washington. I would rate this novel as ‘R’ as there is Mature Language and Mature Situations. The novel is written in the third person with the primary characters being Lexy Cooper and Mike Malick.

Mike Malick is a Detective with the Redmond Police Department. A security guard at the Xenon company campus finds the nude body of a young woman in an adjacent wilderness area. Mike is called to the scene. He soon discovers that the woman’s name is Callie Caldwell and that she was a friend of his “niece”, Lexy. As Mike investigates the case, the evidence points to someone working at Xenon as the murderer. Mike takes advantage of Lexy’s employment at Xenon to get more information on some of the suspects, though he wants her to keep a low profile and play it safe.

Lexy is called by her “uncle” to identify the body of the young woman found on the Xenon campus. Lexy was friends with Callie, though she soon discovers that she did not know Callie as well as she had thought. Lexy begins to investigate those that were close to Calllie at Xenon. She learns a great deal about some of her fellow employees, not all flattering to them.

Lexy’s attention is split between her expanded role at Xenon making videos, poking around in Callie’s past, and trying to sneak as much time as she can with Nate. Finding time to be intimate with Nate is not easy as he is married and has a family.

This was a good mystery, with an engaging plot. I liked the characters that Ms. Charter created for the novel. I give this novel a 5 out of 5.

Mac OS X – Adding an External Disk Drive

We often find ourselves in the position of needing another disk for our system. External drives can be used for added data storage, as a simple backup device, as a Time machine drive, or as a complex
multi-disk RAID array for video production [1]. Adding an external drive to your Mac is very quick and simple. However, there are several questions that you need to ask your self before buying an external disk. That is what this article is about.

How Are You Going to Connect the External Drive?

There are different connection methods that you may have available
on your Mac for adding an external drive. Depending on when your Mac was built and which model it is, your Mac may have a Firewire, a USB and/or a Thunderbolt port for connecting external devices. Actually there are more types of connections than just these three, as there are sub-flavors of both USB and Firewire.

To see what your Mac has available, click on the Apple in the top left corner of your screen >> About This Mac >> More Info >> System Report. Under Hardware look for the Firewire, USB and Thunderbolt entries. You can see which interfaces your Mac has available and which speed they support. When I checked my Mid 2011 Mac Mini, I found that I have Firewire 800, USB 2.0 and Thunderbolt.

Connection Method Speed (megabits/s) Order of performance
Firewire 400 (IEEE 1394-1995) 393.216 4th
Firewire 800 (IEEE 1394b-2002) 786.432 3rd
USB 1.1 12 6th
USB 2.0 480 (effective throughput is limited to 280) 5th
USB 3.0 5000 (usable up to 4000) 2nd
Thunderbolt 10000 (actually 20000 as Thunderbolt supports
two channels at 10000 each)
1st

 

Obviously the faster connection you use the better, but there may be extra costs. USB 3.0 may cost more than USB 2.0, and Thunderbolt will definitely be the most expensive. Since USB 3.0 devices are downwards compatible (they will still work in a USB 2.0, or even a USB 1.1, port, though at down graded performance) you can buy a drive with a faster connection interface than your Mac currently has and it will still work. Since USB 3.0 has become the most common port, most manufacturers have dropped producing USB 2.0 only compatible drives.

Many drive manufacturers build their drives with multiple interfaces
– combination Firewire 800 / USB 3.0 drives are very common.

Most Likely Answer – The general case recommendation if you are buying an external drive today is a Firewire 800 / USB 3.0 Combo (or just USB 3.0) [2]. Generally you would only go to the expense of a Thunderbolt drive if you were primarily running an application that requires a lot of high speed file I/O, such as video editing.

What type of Drive Should I Choose?

There are choices to be made as to the type of disk as well.

SSA – A Solid State Drive will give the most performance, but it will have the highest cost per gigabyte of available storage. They are
highly reliable since they have no moving parts [3] and are extremely quiet for the same reason. A SDD makes much more sense as a boot drive than as an external drive in most cases.

HDDHard Disk Drives are the most common choice, but even then there are alternatives 5400rpm and 7200rpm rotating speeds (Yes. HDDs also come in 10000rpm and 15000rpm, but those are not likely to be available as external drive choices).

Disk rotation speed affects disk performance. For instance, a 5400rpm disk will have a 5.55ms average latency, while a 7200rpm disk will have only a 4.16ms latency. If the applications you generally use perform a large amount of disk I/O, the rotational speed will make a difference. If not, then you will generally be better to go with a 5400rpm drive. For a given price point, you can get a larger capacity drive at 5400rpm.

Most Likely Answer – The general case recommendation would be 5400rpm, unless the application you are using involves a lot of high speed disk I/O. If your budget allows, go for the 7200rpm drive.

Should I get a desktop hard drive or a portable hard drive?

Desktop Drives – The simplest way to differentiate an desktop
versus a portable drive is that a desktop hard drive requires an
external power source, while a portable hard drive can be powered
just by your computer [4]. The desktop’s power supply may seem
unnecessary, but many of the desktop drives will include a fan to keep the drive cooler under heavy operation [4]. In general, the
desktop drives will be able to perform under sustained heavy use
better. If I wanted to move my iPhoto library to an external drive
for my Mac Mini and keep it constantly attached and powered on, I
would choose a desktop drive.

Portable drives – They provide the benefit identified by their name, they are easy to take with you. Since they only need to connect to your computer by the USB, Firewire, or Thunderbolt connection, they are easy to set up, and easy to drop into your computer bag and take along with your laptop. Many portable drives are ruggedized to take the heavier punishment that constantly moving it around can exert. I use a portable 1 TB (terabyte) drive for my Time machine backups. Once a week I attach the drive, update my backup, then put the drive back in a desk drawer.

Most Likely Answer – This depends. Choose a portable drive if portability is needed, or if you are only going to occasionally attach the drive to your computer. If you are leaving the disk attached and running all the time, go for the desktop drive.

How Large of a Drive Should I Get?

When you are choosing an external drive, you should buy enough
space to accommodate your needs for the foreseeable future. How
much space is enough? That depends on what kind of files you are going to be storing, but in any case always get a bigger drive than you currently think you will need.

On the other hand, choosing the largest drive available may not be a
good idea as the largest disks are often at a premium price. Compare
the available drives and see what the price per GB (gigabyte) is (disk cost / disk capacity). Usually you will see that the cost per GB goes down as the size of the disk increases.

Most Likely Answer – buy the largest drive that you can afford. Even if you cannot imagine needing the space now, more than likely you will use it eventually.

Should I Consider Building Instead of Buying the Drive?

Yes, you CAN build your own external drive! Certainly the pre-installed external drives are more popular, but building your own external drive is worth considering.

Pre-installed – The pre-installed external disk is the most popular. Pre-installed external drives come completely assembled with the drive size you specify. They include a warranty that covers the case, drive, cables, and power supply. All you need to do is plug the external drive into your Mac, format the drive, and you’re ready to go.

If you do not have an extra, unused disk drive of the needed capacity, buying a drive enclosure and a new disk drive will probably be more expensive than just buying the pre-installed unit.

Assemble Yourself – Installing a hard drive in an external disk enclosure is an easy task that almost anyone can perform [2]. If you want to assemble your own external disk, then you would buy a hard drive enclosure. It would come with a power supply and hard drive interface. All you would need to do is install the disk drive. The drive you use does not have to be new. Working drives from old computers are often re-purposed as external drives.

External disk enclosures come in three sizes: 1.8″, 2.5″ and 3.5″. This refers to the physical size of the hard disk it can contain. You would pick the enclosure size to match the available drive. Usually you would choose a 3.5″ enclosures unless you are simply trying to make use of an old 2.5″ laptop drive. Power to the enclosure may be supplied by the connecting cable (USB, Firewire, Thunderbolt), but some use an external power supply (wall wart). The 3.5″ enclosures are more likely to have external power adapters.

Also check on the interface internal to the enclosure for the disk itself. The internal interface connecting the drive to the enclosure is usually a SATA (Serial ATA) 2 (3 GB per second) or SATA 3 (6 GB per second) interface [1]. If the enclosure has a USB 3.0, Firewire 800 or Thunderbolt connection to the computer, you will want to insure that the internal interface is the faster SATA 3 and that the drive you are using is compatible with that interface.

Choosing to install the drive yourself usually offers more options. There are many different case styles, and choice in the type of supported connections. You also get to choose the size and brand of the disk. If you are buying a new drive, then you may be able to get a longer warranty on it than you would a pre-installed drive [1].

If you need very large capacity, high I/O or redundancy, then you
may want to pick a muli-bay enclosure. These allow for more than
one disk to be installed, and usually configured in a RAID array.

Most Likely Answer – Both options are good choices. It is mostly a matter of your needs, your skills and your interested level.

Do I Need a RAID Array?

So, what is RAID? If you have the right enclosure with two or more disks, then you can configure the disks into a RAID (Redundant Array of Independent Disks) array. Depending on the number of drives you can configure them as:

RAID 0 – two identical drives where I/O is stripped across the pair (part of the data is written to each disk). This gives no redundancy, but it does improve performance and the capacity of the array is the sum of the two drives. Failure of one drive renders the array unusable.

RAID 1 – two identical drives where the data is mirrored (written identically to both). If you loose one drive, the array continues to function with no data loss. The capacity of the array is the capacity of one drive.

RAID 5 – requires at least three identical disks. Data is written across all disks with distributed parity. If one disk fails, it just needs to be replaced. Because of the distributed parity, the data on the failed disk will be rebuilt on the new drive. No data will be lost from a single disk failure. Capacity of a three disk array is the size of two disks (in a RAID 5 array of N disks, the array capacity will be the total of N-1 disks).

Most Likely Answer – No for most users. RAID is mostly used for those instances where you need a larger capacity than a single disk will provide OR faster I/O than a single disk is capable of OR you need the reliability RAID provides.

Should I Only Consider Local External Drives?

Adding external drive space does not necessarily mean that you connect a disk drive directly to your computer. In some situations using a remote disk makes more sense [5].

Local drives – Local drives are those connected to the computer over USB, Firewire or Thunderbolt cables. Local drives usually have a speed advantage over those connected over a network [5]. Local drives also have the benefit of little or no setup required. In many cases you just take it out of the box, connect it to the computer and you are ready to use it. You may also find that some applications will only work with local drives. Using a local external drive also means that you can take the drive with you to a new work location if needed.

Network Attached drives – You should consider a Network

Attached Storage (NAS) device if there are multiple computers in your home or office that need an external disk. A NAS is essentially a special purpose computer with one or more disks attached. It’s only purpose is to store data (act as a file server).

The disks may be configured in a RAID.

Network attached drives either connect via an Ethernet cable to your home/office network, or in some cases connect with client computers over Wi-Fi. While Wi-Fi connections are very convenient, they are also generally slower. Because of the network connection, setting up a network attached drive and then configuring all of the computers to use it generally requires more in-depth knowledge. Since there are in essence a small computer, network attached drives will be more expensive.

Your OS X Mac can work with many NAS devices. OS X supports Windows file sharing protocols, such as Common Internet File System (CIFS), as well as Apple’s own Apple Filing Protocol (AFP).

Be aware though that Time machine will only work with a network attached drive which supports AFP [5].

Apple does have network attached storage products. Apple offers
the AirPort Extreme ($99) that allows an external USB disk to be connected and shared. Apple also offers the AirPort Time Capsule (2TB $299, 3TB $399) which has an internal drive that can be shared.

Most Likely Answer – Yes, for most users a local drive is the answer.

Should I use a Cloud Service?

There are many cloud storage services available. It is an obvious questions if using those is a viable option for external storage.

Cloud storage – Access to cloud storage is going to be significantly slower than the other possible solutions. There is also the concern as to how secure the data is that is being stored on the cloud service. If the solution does not allow user side encryption, then content stored on cloud sites may be vulnerable, and would certainly be available to law enforcement with a warrant.

There are many cloud storage services, some even offer a limited amount of free disk space. The cost of cloud storage is, at this point, much higher than purchasing a local external drive. This is especially true when you consider a three or five year cost comparison.

Cloud storage solutions do provide you with off site backup if that is desired. They will allow access from anywhere there is network access and many offer some sort of shared access for multiple users.

Using a cloud storage service is a good way of sharing work between computers. I use Dropbox to have common access to files I am working on (like these articles) between my MacBook and Mac Mini. I can then work in my office on my Mac Mini, or go sit in the living room and watch TV while working on the same file. However, I move the files once they are complete to the disk drive on my Mac Mini for archival storage.

You may want to take a look at this very thorough comparison of cloud storage services. Some of the more popular are (data captured 9/8/14):

  • Dropbox – 2 GB free, $9.99/month 1 TB
  • Box – 10 GB free, 100 GB $5/month, unlimited $15/month
  • Google Drive – 15 GB free
  • iCloud – 5 GB free
  • Spideroak – 2 GB free, 100 GB $10 / month
  • Wuala – 5 GB $1.39/ month, 20 GB $3.99/month, 50 GB $6.99/month

Non-cloud storage – By non-cloud storage I refer to either a locally attached disk or NAS device located in the same home or office as the computer. These will always be faster, and will most likely always be lest costly.

Most Likely Answer – No, unless you need off site backup or the ability to share files with others.

Can I just use a Flash Drive?

We all have a few USB Flash Drives that we have picked up over the years. It is reasonable to think about using those for external storage. While these work fine for moving content between computers, they are not good choices for true external storage. The I/O rates, particularly when writing data to the drive, are far lower than for the other storage media I have discussed. The cost per GB is
also going to be higher. These drives also can wear out as they have a low limit on the number of times data can be written to the drive, with some only lasting for 3000 to 5000 cycles of writing
new data.

Saving the only copy of important files on a USB Flash Drive is not
a good idea. Because of their size they are easy to misplace unless
stored in a secure location, and I have sent at least one USB Flash
Drive on a wild ride through my washer and dryer (amazingly that one still worked afterwards, though I have no idea where it is now).

USB Flash Drives do make sense if you have apps or files you want
to carry with you to use on different Macs.

Most Likely Answer – No, generally, though they do have a place for special purpose use.

Is There Anything Else I Should be Aware of?

There are several disk drive specifications that you can look at, particularly as you compare one external drive to another:

Seek time – how long it takes for the heads to travel to the track with the data (a lower number is better)

Latency – delay for the rotation of the disk to bring the desired data under the heads (a lower number is better)

Data Transfer Rate – how long to transfer data from the disk to the buffer. Depends upon rotational speed and data recording density (higher number is better)

Disk Buffer – memory in the disk drive unit that holds recently read sectors, and nearby sectors that may be requested in the future. If the desired sector of data in in the buffer, the data can be returned much more quickly than if it has to be read from the disk itself. (Larger buffers are usually better)

What Kind of Budget Should I Expect?

So how much should you expect to spend? I spent a short time pulling some cost data, but of course this is subject to change on a moments notice. Nor did I do an exhaustive search to find the best prices.

You would want to check with your favorite computer store and see what the current prices are. Most likely you will get the best deals from an on-line store if you are willing to wait a few days for delivery.

The three items listed with 0 GB of storage are empty enclosures that you can add your own drive to.

The cost per GB of storage for those drives supporting RAID is calculated on the usable storage available, not the total storage.

What do I need to do to Use the Drive?

Your Mac uses the HFS+ filesystem while Windows computers use
NTFS. Linux based computers use yet other filesystems. The external disk you purchase will only be formatted one way, often with NTFS as the majority of computers are currently Windows based.  As mentioned above, your Mac with OS X will be able to access an NTFS formatted disk. If you are wanting to share the disk between multiple computers running different operating systems, then NTFS is going to be the best choice. OS X, Windows and Linux systems can all access a NTFS formatted drive.

Most Likely Answer – For Mac exclusive use, reformat the drive to HFS+.

To format the drive attach the drive to your Mac >> open a Finder window >> open Applications >> open Utilities >> double click on Disk Utility. Select the drive device to be formatted (above list of storage volumes on the device, often with the manufacturer name and size  CAUTION – be sure you are selecting the correct drive to format! ) >> choose ‘Partition’ tab >> select ‘1 Partition’ from drop down menu >> click the Options button and ensure that ‘GUID’ is selected as the partition scheme >> click the Apply button [6].

In the example shown below I am reformatting the 160.04 GB Seagate Freedom device. Format

Book Review of “PsyBot”

“PsyBot” was published in 2014 and was written by Nowick Gray (http://nowickgray.com). Mr. Gray has published two novels, “PsyBot” being his second.

I obtained a galley of this novel for review through https://www.netgalley.com. What I read of this Science Fiction novel is written in the first person, with the primary character being Joe Norton.

Joe is approaching middle age and is in a loose relationship with Moira. While they are not exclusive to one another, the relationship starts to fall apart when Moira mistakenly thinks Joe has been sleeping with her sister Sheila. To make matters worse, after they have a argument over it, Joe does sleep with Sheila.

Sigh . . . I really tried with this novel, reading thru chapter 3 (about 23% of the book). At that point I gave up as I could not discern what the plot was. This is the first NetGalley novel I have just put down and walked away from. I give this novel a 1 out of 5.

My book reviews are also published on Goodreads (https://www.goodreads.com).
