I put together a UNIX security model diagram with an application called XMind. In the coming weeks I will be blogging in more detail on each of these areas and components and will be using as my guinea pig, Ubuntu 9.10 to see how much work is necessary to conform the system to the model. Please return for more UNIX geeking out.
For our next lesson in logic again we begin with a reference from Isaac Watts book on logic:
“In our own studies, as well as in the communication of your thoughts to others, merely for their information, avoid ambiguous and equivocal terms as much as possible.”
Not to insult anyone’s intelligence, but one of my pet peeves is to define the terms I’m reference before I use them. That being said let’s look to our friend Google for the definition of the term “Ambiguity”:
Ambiguity
Definition 1: An expression whose meaning cannot be determined from its context.
Definition 2: A property of being ambiguous, where a word, term, notation, sign, symbol, phrase, sentence, or any other form used for communication, is called ambiguous if it can be interpreted in more than one way.
Definition 3: Having no intrinsic or objective meaning; not organized in conventional patterns; “an ambiguous situation with no frame of reference”; “ambiguous inkblots”
So I think 3 definitions is enough and you get the picture; Given a proposition there must be a clear symbolic link (Linux does apply to non-tech stuff) between the terms being used and the totality of the statement being said. The most obvious spectrum for where this is violated is in politics and in an area where arguments are presented and conclusions are drawn based on the validity of the arguments demonstrated. So I’m use the format of showing this between a “good” and “bad” statement for avoiding ambiguity.
Bad Example: John Wayferd entered his cubicle looking very green.
Good Example: John Wayferd entered his cubicle looking green in the face from a night of all night drinking.
So we can see from the two examples given above that what separates the good from the bad is the qualifications used to provide context for the term “green” used in our “good” example.

Direct. I. Labour to know God, and to be affected with his attributes, and always to live as in his sight.—No man can know sin perfectly, because no man can know God perfectly. You can no further know what sin is than you know what God is, whom you sin against; for the formal malignity of sin is relative, as it is against the will and attributes of God. The godly have some knowledge of the malignity of sin, because they have some knowledge of God that is wronged by it. The wicked have no practical, prevalent knowledge of the malignity of sin, because they have no such knowledge of God. They that fear God will fear sinning; they that in their hearts are bold irreverently with God, will, in heart and life, be bold with sin: the atheist, who thinks there is no God thinks there is no sin against him. Nothing in world will tell us so plainly and powerfully of the evil of sin, as the knowledge of the greatness, wisdom goodness, holiness, authority, justice, truth, &c. of God. The sense of his presence, therefore, will revive our sense of sin’s malignity.
Direct. II. Consider well of the office, the bloodshed, and the holy life of Christ.—His office is to expiate sin, and to destroy it. His blood was shed for it: his life condemned it. Love Christ, and you will hate that which caused his death. Love him, and you will love to be made like him, and hate that which is so contrary to Christ. These two great lights will show the odiousness of darkness.
Direct. III. Think well both how holy the office and work of the Holy Ghost is, and how great a mercy it is to us.—Shall God himself, the heavenly light, come down into a sinful heart, to illuminate and purify it? And yet shall I keep my darkness and defilement, in opposition to such wonderful mercy? Though all sin against the Holy Ghost be not the unpardonable blasphemy, yet all is aggravated hereby.
The next section in this blog entry that I’m going to cover is how you retain all of those wonderful ideas that have obtained using the previous steps. Mr. Watts give us a directive that is outlined as:
| Direct II. Use the most proper methods to retain that treasure of ideas which you have acquired; |
| for the mind is ready to let many of them slip, unless some pains and labour be taken to fix them upon the memory. And more especially let those ideas be laid up and preserved with the greatest care, which are most directly suited, either to your eternal welfare as a Christian, or to your particular station and profession in this life; |
| for though the former rule mends a universal acquaintance with things, yet it is but a more general and superficial knowledge that is required or expected of any man, in things which are utterly foreign to his own business; but it is necessary you should have a more particular and accurate acquaintance with those things that refer to your particular province and duty in this life, or your happiness in another. |
OK, Justin that’s all well and good, but am I supposed to do with that? I’m glad you asked that question, because there is a contemporary tool available to you to retain any and all ideas you may come up with:
Chandler – Chandler is a software application that is essentially a “To-Do” list on steroids. You can also access your calandar through a web portal and you can share lists and calandars between you and friends.
Goto Chandler for more details.
Notebook – I know this is old-school and if you have a Blackberry or a PDA, you can use that, but the bottom line is have some sort of material whereby you can record your ideas as they form in your brain, because internal memory only goes so far.

My Blogging from the reading of Richard Baxter’s, “A Christian Directory”, continues. In this blog entry Baxter outlines the duties of human speech that consist of:
1. To glorify God by the magnifying of his name; to speak of the praises of his attributes and works.
2. To sing psalms of praise to him, and delight our souls in the sweet commemoration of his excellencies.
3. To give him thanks for the mercies already received, and declare to others what he hath done for our souls and bodies, for his church and for the world.
4. To pray to him for what we want, and for our brethren, for the church, and for the conversion of his and our enemies.
5. To appeal to him and swear by his name when we are called to it lawfully.
6. To make our necessary covenants and vows to him, and to make open profession of our belief, subjection, and obedience to him, before men.
7. To preach his word, or declare it in discourse, and to teach those that are committed to our care, and edify the ignorant and erroneous as we have opportunity.
8. To defend the truth of God by conference or disputation; and confute the false doctrine of deceivers.
9. To exhort men to their particular duties, and to reprove their particular sins; and to endeavor to do to them good as we are able.
10. To confess our own sins to God and man as we have occasion.
11. To crave the advise and help of others for our souls; and inquire after the will of God, and the way to salvation.
12. To praise that which is good in others, and speak good of all men, superiors, equals, and inferiors, so far as there is just ground and cause.
13. To bear witness to the truth, when we are called to it.
14. To defend the cause of the just and innocent, and vindicate them against false accusers.
15. To communicate and convey to others the same good impressions and affections of mind, which God hath wrought on us, and not only the bare truths themselves which we have received.
16. Lastly, to be instruments of common converse; of expressing our mutual affections and respects, and transacting all our worldly business: for learning, arts, manufactures, &c.

Richard Baxter gives some sound advise to follow of thieves that should be avoided:
Thief I: One of the greatest time-wasting sins consists of idleness or sloth. One only needs to read the book of Proverbs to see this point expounded. Remember that you run for the immortal crown; and therefore see that you lose no time, and look not at the things that are behind;
Thief II: The next thief or time-waster is excess of sleep.
Thief III: The next thief or time-waster is an inordinate adorning of the body. This would include clothing, jewelry, and the like.
Thief IV: Another time-wasting thief is unnecessary pomp and curiosity in retinue, attendance, house furniture, provision and entertainments, together with excess of compliment and ceremony, and servitude to the humors and expectations of time-wasters.
Thief V: Another time-wasting sin is needless and tedious feastings, gluttony, and tippling. O remember, while you are eating and drinking, what a corruptible piece of flesh you are feeding and serving; and how quickly those mouths will be filled with dust! and a soul that is posting so fast to eternity, should find no time to spare for vanity; and that you have important work enough to do, which is performed, will afford you a sweeter and a longer feast.
Thief VI:Another time-waster is idle talk.
Thief VII: Another thief which by the aforesaid means would steal your time, is vain and sinful company. Remember, assimilation begets association.
Thief VIII: Another notorious time-wasting thief, is needless, inordinate sports and games, which are stigmatized by the offenders themselves, with the infamous name of pastimes, and masked with deceitful title of recreations; And to think that they sold that precious time for a little fleshly sport, in which they should have been working out their salvation , and making their calling and election sure.
Thief IX:Another time-wasting thief is excess of worldly cares and business. Not much needs to be said of this as there a plethora of examples within our society.
Thief X: Another time-waster is vain ungoverned and sinful thoughts.
Thief XI: Another dangerous time-waster sin is the reading of vain books , play-books, romances, and feigned histories; and also unprofitable studies, undertaken but for vain-glory, or the pleasing of a carnal or curious mind.
Thief XII: But the master-thief that robs men of their time is an unsancitified , ungodly heart; for this loseth time whatever men are doing;because they never intend the glory of God;

“Direction I: Furnish yourselves with a rich variety of ideas; acquaint yourselves with things ancient and modern; things natural, civil, and religious; things domestic and national; things of your native land, and of foreign countries; things present, past, and future; and above all, be well acquainted with God and yourselves;” Logic: The Right Use of Reason in the Inquiry after Truth – Isaac Watts, Page 69.
To be successful with any idea is to have lots of ideas. One word of caution; If you out of blue experience an idea that no one seems to have thought of, you need to find out why first. It could be because someone smarter than you saw problems or potential roadblocks for that specific idea.
When in doubt, always perform through research on your ideas if you are planning on using them to design or build something and thereby to avoid potential roadblocks down the road.
The list below is by no means a comprehensive methodology for generating ideas, but I think it is a good start and as you use the tools and methods suggested you will most likely come up with your own.
