RAM How To Boot Test Diagnose and Replace It — Part-2

Fig.1. RAM Card, 2GB DDR2 800MHz. You should avoid touching the gold connectors.
In this post we do a walk-through of the process of installing new RAM. The first post explored how to diagnose faulty RAM.

RAM that is faulty will occasionally cause your system to reboot. To correct this problem the RAM must be replaced.

Now, if you’ve got this far then you you know that my system occasionally reboots without warning. You know that I have established that malware is not to blame. No known driver issues and I’ve even made peace with the fact that my RAM failed me.

In Fig.1 at right is a top and bottom view of the replacement RAM card, 2GB DDR2 rated at 800MHz. You should take care not to touch the gold connectors, and rather handle the card by it’s short edges. For the replacement RAM I went to a local supplier here in Hermanus. You can find them online here.

Juan-Pierre of Matrix Wharehouse says: “It’s a 2GB DDR2 PC6400 RAM module that runs at an effective speed of 800Mhz. The actual speed of the memory is 400Mhz, but because it is DDR RAM, it is doubled as the transfer rate is doubled as well. Also, you will get a higher transfer rate if you connect two of the same memory modules, therefore giving you dual channel transfer speeds.”

You will hear these words, or at least think about them, when next you experience faulty RAM components. This can happen to you.

Random and without warning are four words that you do not want to hear used with computing terms like “shutdown” and particularly and ironically not together with the words “Random Access Memory” or RAM.

Just recently my computer has started occasionally rebooting spontaneously without perceivable cause. My motivation for fixing this problem is based on Van Haelen’s 3rd proposition, which, as you are no doubt aware, is based on premise that this reboot will happen right before you have saved your work and right after you have entered some critically important data, which will now be gone. The well known rider to this proposition is that the random reboot will never happen when you are playing Spider Solitaire or similar. Here’s my experience with diagnosing the problem and replacing the faulty RAM. Continue reading RAM How To Boot Test Diagnose and Replace It

Deepest Sea Shoot for Avatar Sequel in the Marianas Trench

Artists impression: the bathyscaphe 'Trieste' in the Marianas Trench, the deepest ocean on earth (click to enlarge)

The author of Avatar, James Cameron, is assembling a team to dive to the bottom of the deepest sea. He is planning to shoot footage for a sequel to Avatar. The movie is set in the turbulent waters of Pandora, an alien moon, and it’s expected to hit the circuit in 2014. Cameron has commissioned Australian engineers to build a deep sea submersible to reach the bottom of the Marianas Trench.

“We are building a vehicle to do the dive. It’s about half-completed in Australia,” said Cameron.

Camerons destination is an area known as “Challenger Deep”. At 10 916 meters (35 813 feet) below sea level, this is the deepest surveyed point on earth. It lies in the hadopelagic or Hadal zone so named from the greek word ” Hades” for the “underworld.”

This deepest part of the ocean floor has been visited only once before, in January of 1960, and never since.   Continue reading Deepest Sea Shoot for Avatar Sequel in the Marianas Trench

The Beautiful Bot River Estuary

The Bot River Estuary (click to enlarge)

Last year I took this photo of the lovely Bot River estuary. We are privileged to live within walking distance of its shores. You may notice, if you look up at the top of this page, the banner-header of this website is cropped from the same photograph.

Time and time again I am drawn to try and capture the most astonishing variety of moods and vistas that are on display throughout the year as the seasons change.

This estuary is situated in the Kogelberg Biosphere Reserve on the southern coast of South Africa. It lies at the bottom of a broad and fertile valley and measures about six by two kilometres.  It is quite shallow with an average depth of 1 – 2 metres (3 – 6 feet).  The Bot and Afdaks rivers feed this estuary which seasonally opens to the sea. This ensures a rich variety of fauna, some 32 species of fish and over 50 kinds of birds including pelicans, flamingos and the other waders. Most are migratory and so are seen at different times of the year. Occasionally a herd of wild horses grazes on the grassy banks (12 images, click here for Flickr slide show).

Quotation Mark And Space After Period: Rules You Should Know About

Punctuation Rules You Need to Know

Have you ever wondered, like me, if one or two spaces should come after a period in a sentence? Well, we are not alone. Apparently there is a dichotomy of opinion on this issue. Strongly held views are asserted by each camp. For the one-spacers, Farhad Manjoo puts it best:

“Typing two spaces after a period is totally, completely, utterly, and inarguably wrong.”

Well, alright then. Not long ago, mere hundreds of years back, inconsistency reigned regarding spelling, punctuation and print design. In the early 20th century typesetting eventually became more widespread. Typesetters began to settle on a single space after the “full stop.” Europe was first to adopt this and America followed soon after. Then came a now virtually extinct technology — the manual typewriter. The first typewriters had mono-space type. The introduction of the two-space rule was to accomodate the aesthetic shortcomings of the mono-space typewriter. Continue reading Quotation Mark And Space After Period: Rules You Should Know About

The Hunter Gatherer Diet and How to Fast Your Way to Better Health

The Hunter Gatherer's diet was not like our modern diet

Last night I was up at midnight with my better half indulging in what is known as “the midnight snack.” Why am I telling you this? Because we spontaneously decided to commence with what will henceforth be known as our first thirty-hour-fast. Right after the midnight snack, that is. As I write this to you now, I’m fasting. We will not be eating anything at all, today. Or tonight. Not till tomorrow morning will anything but liquid pass these lips of ours. So far so good. Watch this space for a follow-on as to how this went.

Lately I have been reading about how to “stimulate the caveman” in you. There are some great links here and here. Before the start of the agricultural period about 10,000 years ago man was a hunter-gatherer. Before this period, for the almost unimaginably long time of three million years, our diet contained an enormous variety of plant foods and was high in protein. There was nearly a complete absence of grains and simple carbohydrates in the hunter-gatherer diet. The closest thing to a carbohydrate was honey, Continue reading The Hunter Gatherer Diet and How to Fast Your Way to Better Health

10 Things I Have Done That You Probably Haven’t

South African Karoo

This is a meme doing the internet rounds at the moment. Feel free to leave your own list in the comments below. In no particular order, here is my contribution:

1. Shot a running wild peacock at 300 meters
At the age of thirteen I hunted and shot a running ‘Po’, a type of wild peacock, in the Karoo desert of South Africa with a .222 Remington Swift rifle. It was 300 meters (about 1 000 feet) away and running away from me, dodging from side to side. With that single shot I instantly achieved a reputation with the locals as “die Engelsman wat kan skiet”. Translated this means “the Englishman that can shoot”.

2. Bungi jumped off the Gouritz River Bridge
This bone-chilling 22 storey high Bungi jump is on the beautiful east-coast Garden Route near Knysna, South Africa. Continue reading 10 Things I Have Done That You Probably Haven’t

Language of Afrikaans and Khoisan Two of 24 Spoken in South Africa

Khoisan engraving in a riverbed on a farm in the Kalahari
Not many people know that 24 living languages are spoken in South Africa today. Of these, according to some estimates, Afrikaans is spoken by around 23 million people, or 46% of the population of nearly 50 million people.

At the other end of the scale, an almost extinct Khoisan language known by various names, including Ng’uki, is spoken by just 12 known individuals. These rare Ng’uki speakers are scattered about South Africa in isolated ‘ones’ and ‘two’s’.

The next smallest group numbers just 87 persons. They speak a marginal Khoisan language called Xiri. Also known as Grikwa or Griqua, it will soon join the other now extinct Khoisan languages of Seroa, Korana and Xam. The Khoisan were the original inhabitants of Southern Africa. The Bantu migrations from Central and East Africa towards the south eventually reached the southern African region, replacing the Khoisan as the predominant population. Today the largest Khoisan language group numbers 50 900 (2006) Continue reading Language of Afrikaans and Khoisan Two of 24 Spoken in South Africa

Eight years ago Dan Balsam received one too many emails inviting him to take advantage of an offer to enlarge his breasts. The rest is history. Dan launched a web site called danhatesspam.com, quit his job in marketing to go to law school and is now making a living suing the authors of emails offering miracle drugs, free sex and mail order brides.

Spam now accounts for 90% of all email, upwards of 200 Billion emails a day, according to Cisco Systems Inc. That’s a lot of email. ” I feel like I’m doing my bit to clean up the internet” says Dan.

Starting in 2000 Dan used the small claims court system with considerable success. Six years later he was graduating from the University of California Hastings College Law School. By then, some of his cases were being heard in the 9th U.S. Circuit Court of Appeals. He was now taking on the big guys such as Valueclick Inc and AdultFriendFinder.com, the latter after they sent Dan four emails to four different accounts all with the same subject line: “Hello my name is Rebbecca and I love you”.
