Something to ponder









Makes you think......

Home Made HEALTHY Hot Chocolate


Yummy - I have thought out a Hot Chocolate recipe and it works !!!! Very yummy and guess what -- no sugar, no dairy........ very, very guilt free.

Very Easy - combine one medium tin of Cocoa with one packet of Nature's Choice Swiss Dream milk replacement (approx 1:1) .

Password complexity....are we fooling ourselves ?

Many of the beliefs we have around what constitutes a “good” password are created by what default policies in software such as Microsoft teach us.
We are led to believe that a minimum length of 8 characters, a good mixture of UPPER and lower-case, numbers and uncommon (i.e. $@#&!) characters automatically make a good password.
Many Systems Administrators and Systems Engineers never delve into the analysis behind a password due to the above IT MEME created in large by the software industry. So what constitutes a strong password and why is our MEME a concern. Surely our passwords have stood the test of time.
What we need to keep in mind is that computing power has been increasing at an incredible rate and access to this computing power has become easier and easier. Lately, harnessing the power of multiple GPU’s has become the standard method to crack passwords. A recent password cracking cluster built with easily accessible hardware, managed to show that it could crack every standard Windows password in less than 6 hours. (GPU Cluster cracks passwords)
This is seriously scary tech for anyone connected with security on networks. Gone are the days of setting a password and never touching it again - at Windows complexity levels, that is. Even changing passwords regularly is no guarantee against a machine that only needs 6 hours to crack open ANY Windows password.
What shall we then do ?
First of all, we need to understand what makes a password difficult to crack. The key here is LENGTH. Sure, complexity plays a factor, but complexity becomes self defeating if a user cannot remember their own password. Force them to change this complex password every week or month and they WILL start writing it down. This then defeats the object of the exercise, as written down passwords can be snooped and are a very high risk.
Some facts:
A password of 8 characters (only a-z + A-Z) can be cracked by a Supercomputer in approx 5 millionths of a second (0.0005s) or in about 11 seconds by a PC + GPU. This password has an entropy (password strength) value of 45.6 bits.
A password of 8 characters containing a-z, A-Z, 0-9, special characters (`~!@#$%^&*()-_=;:'",<.>?) will take a Supercomputer 0.05 seconds to crack and a PC + GPU only 17 minutes.
Keeping the password simple (a-z + A-Z), but increasing the length by only 2 characters ( from 8 to 10 ) will make the Supercomputer take 1 second to crack it and the PC + GPU crack time increases to 8 hours !
Adding another 2 characters now makes our 12 character password crackable in 1 hour by Supercomputer, but our PC + GPU will now take 2 YEARS ! Password entropy has now increased to 68.4 bits.
Should we become creative and construct our password as an easy to remember object of some length such as “MydogsnameisButch” (17 characters) with an entropy of 96.9bits, our Supercomputer now needs 47,125 YEARS and our PC + GPU needs 942 MILLION YEARS to crack this !
On top of being very difficult to crack (by a computer), our password has the advantage of being easy to remember.
This does not mean that ALL restrictions must be removed from password complexity. A good requirement would be 12-16 characters, at least 2 Uppercase and no more than 2 consecutive repeated letters. The 16 character limit allows the password to be used in a Windows environment. The above password would have to be changed to “MydogsNameisBob” (Entropy value of 85.5 bits)
In general, an entropy of over 80 is considered to be a very strong password.

1000 albasters...


Uit die pen van Corné Grundling (Ex SAUK Joernalis)

               "Hoe ouer ek word, hoe meer geniet ek Saterdagoggende.
Miskien is dit die stil alleenheid wat daarmee kom om eerste op te staan, of miskien die uitbundige vreugde om nie werk toe te gaan nie.
Hoe dit ookal sy, die eerste paar ure op 'n Saterdagoggend is die lekkerste..

       "'n Paar weke gelede was ek op pad na die motorhuis met 'n stomende koppie koffie in die een hand en die oggendkoerant in die ander hand. Wat as 'n tipiese Saterdag begin het sou draai in een van daardie lesse wat die lewe van tyd tot tyd vir 'n mens gee. Laat ek vir jou hiervan vertel.

       "Ek is 'n radioamateur en het my ontvangstoestel ingeskakel op die telefoniese band om na die Saterdagoggend gesprekke te luister. Met die luister na die gesprekke kom ek af op 'n man wat ouerig klink, met 'n sterk sein en 'n goue stem. Jy weet 'n stem wat klink of hy in die uitsaaiwese hoort. Hy was besig om te vertel, wie ookal wou luister van 'n ding met 'n duisend albasters. Ek was skielik geinteresseerd en besluit om te luister na wat hy te sê  het.

       "'Wel Tom, dit klink sekerlik dat jy baie besig is in jou werk.
Ek is seker dat hulle jou goed betaal, maar dit is hartseer dat jy soveel weg is van die huis en jou gesin. Dit is moeilik om te glo dat 'n jong man sestig tot sewentig uur 'n week moet werk om deur te kom. Dit is hartseer dat jy jou dogter se dansopvoering gemis het. Maar laat ek jou iets vertel wat my gehelp het om my prioriteite reg te hou.'

       "Dit is toe wat die man sy teorie van 'n duisend albasters verduidelik.
       "'Jy sien, ek het eendag gesit en 'n bietjie somme gemaak. Die gemiddelde persoon leef 75 jaar. Ek weet, sommige leef meer en sommige minder, maar gemiddeld, leef mense ongeveer 75 jaar.

       "'Wat ek toe doen is om 75 te vermenigvuldig met 52 en ek het die getal 3900 gekry - dit is die aantal Saterdae wat die gemiddelde mens in sy hele leeftyd het. Hou nou net 'n bietjie uit Tom, ek kom nou by die belangrike deel. Ek het eers op die ouderdom van 55 jaar begin dink aan hierdie detail, en by daardie tyd het ek reeds deur meer as 2800 Saterdae geleef. Ek had nog ongeveer 'n duisend Saterdae oor om te geniet. So het ek na die speelgoedwinkel gegaan en al die albasters in die winkel gekoop.
Uiteindelik moes ek by nog twee speelgoedwinkels ingaan om by 'n 1000 albasters uit te kom. Ek het die albasters huis toe geneem en hulle in 'n groot, helder deursigtige plastiese fles geplaas - alles hier in my stoorkamer langs al my goed.

       "'Van daardie dag af het ek elke Saterdagoggend een albaster uitgehaal en weggegooi. Ek het agtergekom soos ek die albasters sien minder raak, ek al meer gefokus het op die regtige belangrike dinge in die lewe.

       "'Daar is niks soos om te sien hoe jou tyd op die aarde besig is om uit te hardloop, om jou te help om jou prioriteite reg te kry nie.

       "'Wel, laat ek jou vertel voordat ek van die lug afgaan om my lieflike vrou vir ete uit te neem. Vanoggend het ek die laaste albaster uit die fles gehaal. Ek reken indien ek dit volgende Saterdag maak, is ek 'n klein bietjie ekstra tyd gegun. En die een ding wat ons almal kan gebruik is 'n klein bietjie ekstra tyd.

       "'Dit was lekker om met jou te kon gesels, Tom, ek hoop jy spandeer meer tyd met jou gesin, en ek hoop ons ontmoet weer hier op die lug. Dit is 'n 75-jarige ou man, K9NZQ wat groet, oor en uit.'

       "Jy kon 'n speld op die lug hoor val toe die man van die lug afgaan.. Ek reken hy het vir ons almal iets gegee om oor na te dink. Ekself het beplan om die oggend te werk aan die antenna van my radio, en daarna was ek van plan om met 'n paar van die ander radioamateurs saam te werk aan ons klub se nuusbrief.

       "Ek het egter - instede daarvan om dit te doen - die trappe opgeklim na ons slaapkamer en my vrou met 'n soen wakker gemaak. 'Komaan my vroutjie,
ek neem vir jou en die kinders vir ontbyt. Sy het regop gesit met 'n glimlag: 'Wat het gemaak om dit mee te bring?' Ek het na haar gekyk en gedink hoe gelukkig ek is. 'Ag wat, niks besonders nie, dit is slegs 'n lang tyd gelede dat ons 'n Saterdagoggend saam met mekaar en met die kinders spandeer het. En terwyl ons nou uitgaan, kan ons stop by die speelgoedwinkel? Ek het nodig om albasters te koop.'"

Working in Cape Town -- against all logic

My wife and I have been blessed enough to be working in Cape Town, after following what some might describe as a totally illogical path - resigning from 2 well paid, permanent jobs to work respectively, for herself and me, on contract for 12 months. We asked the Lord to help us to Cape Town, and he did. We trust that He will provide the opportunity, both in business for my wife and in personal growth and commitment from my side to enable us to grow and prosper to the point where we can help others both in guidance and financially.


God is good!

The Cracked Pot

Author Unknown
(This is not my work, but I felt it was an important message and had to be posted here....)

A water bearer in India had two large pots, each hung on the end of a pole which he carried across his neck. One of the pots was perfectly made and never leaked. The other pot had a crack in it and by the time the water bearer reached his master's house it had leaked much of it's water and was only half full.
For a full two years this went on daily, with the bearer delivering only one and a half pots full of water to his master's house. Of course, the perfect pot was proud of its accomplishments. But the poor cracked pot was ashamed of its own imperfection, and miserable that it was able to accomplish only half of what it had been made to do.
After two years of what it perceived to be a bitter failure, it spoke to the water bearer one day by the stream. "I am ashamed of myself, and I want to apologize to you." "Why?" asked the bearer. "What are you ashamed of?" "I have been able, for these past two years, to deliver only half my load because this crack in my side causes water to leak out all the way back to your master's house. Because of my flaws, you have to do all of this work, and you don't get full value from your efforts," the pot said.
The water bearer felt sorry for the old cracked pot, and in his compassion he said, "As we return to the master's house, I want you to notice the beautiful flowers along the path."
Indeed, as they went up the hill, the old cracked pot took notice of the sun warming the beautiful wild flowers on the side of the path, and this cheered it some. But at the end of the trail, it still felt bad because it had leaked out half its load, and so again the pot apologized to the bearer for its failure.
The bearer said to the pot, "Did you notice that there were flowers only on your side of your path, but not on the other pot's side? That's because I have always known about your flaw, and I took advantage of it. I planted flower seeds on your side of the path, and every day while we walk back from the stream, you've watered them. For two years I have been able to pick these beautiful flowers to decorate my master's table. Without you being just the way you are, he would not have this beauty to grace his house."
Each of us has our own unique flaws. We're all cracked pots. But if we will allow it, God will use our flaws to grace his table. In God's great economy, nothing goes to waste. Don't be afraid of your flaws. Acknowledge them, and you too can be the cause of beauty. Know that in our weakness we find our strength

Waiting for God

The hardest part about faith is that it is just that - faith - nothing concrete, nothing "there" to focus on, to see. Faith is believing in that which we cannot see, hear, touch or sense in any normal way. Thus, if we have prayed to God to provide us with a solution, we must have faith that He will provide it, for that is what He promises in His word. Of course we have to do what we can from our side - we do the possible, God deals with the impossible. Two thing that are hard, for me especially, to remember are this: 1, even though we do what we can, we still only do it through God's grace and power, thus He must get all the credit, and 2, God will do the rest IN HIS TIME, which usually has NOTHING to do with our concept of time. I am usually stressed and in a semi-panic when God puts His hand on my shoulder and says (I imagine with a slight smile on His face) "What are you worried about, don't you trust me - see, here is the solution."

When life throws you around........

One life lesson I have learned with the help and encouragement of my lovely wife, is that when life throws you around and you feel as though you are going to come crashing down on your head, don't try to land on your feet - land on your knees !

From your knees you look up at the world, you learn the right attitude. From your knees you are equal to your fellow man. On your knees you are vulnerable. On your knees you are closer to the earth - away from worldly comforts. And lastly, on your knees you learn to get to the point before your knees start killing you !

God listens when we are on our knees - not because He wants us to suffer or be uncomfortable, but because when we are on our knees He knows our focus is on Him and we are serious. On our knees we show God that we do not think we are better than our brothers or sisters on earth and that we are not ashamed to show others that we are praying to God. On our knees we are also an encouragement for our fellow Christians as God wants us to be. 

So land on your knees and God will help you to your feet.
