daily quotation server archives

In the late 90’s I started (a good decade for starts) a daily quotation server project at www.quoteserver.ca. The domain is now defunct—some pages are partially viewable at the Way Back Machine.

Below is the list of quotes I had collected by the end of the life of the project. Most are about love—duh—and a few are jolly jests from funny trenches. You know, that place where mustard gas makes your eyes water.

The quotes weren’t scraped from quote archives—each is meaningful and hand-picked.

the quote archive

And now for full list of 1,600 other things worth reading. Such as everything Dorothy Parker has written and ... yes, even the Pinky and Brain quotes, which are a special kind of special.

Quote collections about love, heart, desire, life, death, god, mind, science.

Quotes about life

2
I have no wit, no words, no tears;
My heart within me like a stone
Is numb’d too much for hopes or fears;
Look right, look left, I dwell alone;
I lift mine eyes, but dimm’d with grief
No everlasting hills I see;
My life is in the falling leaf:
O Jesus, quicken me.
Christina Georgina Rossetti
A Better Ressurrection
3
My life is like a faded leaf,
My harvest dwindled to a husk:
Truly my life is void and brief
And tedious in the barren dusk;
My life is like a frozen thing,
No bud nor greenness can I see:
Yet rise it shall — the sap of Spring;
O Jesus, rise in me.
Christina Georgina Rossetti
A Better Ressurrection
9
Howbeit, to meet you grows almost a pang
Because the pang of parting comes so soon;
My hope hangs waning, waxing, like a moon
Between the heavenly days on which we meet:
Ah me, but where are now the songs I sang
When life was sweet because you call’d them sweet?
Christina Georgina Rossetti
Monna Innominata: A Sonnet of Sonnets, i

Little fly, thy summer’s play
My careless hand hath brushed away.
Am not I a fly like thee,
Or art not thou a man like me.
For I dance, and drink, and sing
Till some blind hand doth brush my wing.
If that is life, and strength, and breath
And the word of thought is death
Then am I a happy fly?
If I live, or if I die.
William Blake
36
The mind has a thousand eyes,
And the heart but one;
Yet the light of a whole life dies,
When love is done.

With my lost saints,—I love thee with the breath

I shall but love thee better after death.

Christina Georgina Rossetti
A Birthday
132
To-morrow, and to-morrow, and to-morrow,
Creeps in this petty pace from day to day
To the last syllable of recorded time,
And all our yesterdays have lighted fools
The way to dusty death.
Out, out, brief candle!
Life’s but a walking shadow, a poor player
That struts and frets his hour upon the stage
And then is heard no more: it is a tale
Told by an idiot, full of sound and fury,
Signifying nothing.
William Shakespeare
Macbeth, V. i. 19.

workings of nature. And now to business,
I will explain ...

And in short measures life may perfect be.

In our age ... men seem more than ever prone to confuse wisdom with knowledge, and knowledge with information, and to try to solve problems of life in terms of engineering.
T.S. Eliot
566
For a long time it had seemed to me that life was about to begin, real life. But there was always some obstacle in the way, something to be gotten through first, some unfinished business, time still to be served, a debt to be paid. Then life would begin. At last it dawned on me that these obstacles were my life.

Seneca
Epistulae Morales
1082
O God! methinks it were a happy life,
To be no better than a homely swain;
To sit upon a hill, as I do now,
To carve out dials, quaintly, point by point,
Thereby to see the minutes how they run,
How many make the hour full complete;
How many hours bring about the day;
How many days will finish up the year;
How many years a mortal man may live.
William Shakespeare
Henry VII, Part III, II.v.21
1084
Nor stony tower, nor wall of beaten brass,
Nor airless dungeon, nor strong links of iron,
Can be retentive to the strength of spirit;
But life, being weary of these worldly bars,
Never lacks power to dismiss itself.
William Shakespeare
Julius Caesar, I.iii.93
1092
For the crown of our life as it closes
Is darkness, the fruit there of dust;
No thorns go as deep as the rose’s,
And love is more cruel than lust.
Time turns the old days to derision,
Our loves into corpses or wives;
And marriage and death and division
Make barren our lives.

Something mighty and sublime, leave behind to conquer time.

Ships that pass in the night, and speak each other in passing,
Only a signal shown, and a distant voice in the darkness.
So on the ocean of life we pass and speak one another.
Only a look and a voice; then darkness again and a silence.

And their lives by the moans of their hearts.

You may give me my roses now!

1190
I cannot starve thee out: I am thy prey
And thou shalt have me; but I dare defend
That I can stave thee off; and I dare say,
What with the life I lead, the force I spend,
I’ll be but bones and jewels on that day,
And leave thee hungry even in the end.
Edna St. Vincent Millay

I learned this, at least, by my experiement;
that if one advances confidently in the
direction of his dreams, and endeavors
to live the life which he has imagined,
he will meet with a success unexpected in common hours.
Henry David Thoreau
Walden
1210
I went to the woods because I wished to live deliberately,
to front only the essential facts of life, and see if I could
not learn what it had to teach, and not, when I came to die,
discover that I had not lived.
Henry David Thoreau
Walden
1220
I looked and saw your heart
In the shadow of your eyes,
As a seeker sees the gold
In the shadow of the stream;
And I said, "Ah me! what art
Should win the immortal prize,
Whose want must make life cold
And Heaven a hollow dream?"

Lady, lady, should you meet
One whose ways are all discreet,
One who murmurs that his wife
Is the lodestar of his life,
One who keeps assuring you
That he never was untrue,
Never loved another one ...
Lady, lady, better run!

Alcohol is the anesthesia by which we endure
the operation of life.
George Bernard Shaw
1429
Love loves for ever,
And finds a sort of joy in pain,
And gives with nought to take again,
And loves too well to end in vain:
Is the gain small then?
Love laughs at "never",
Outlives our life, exceeds the span
Appointed to mere mortal man:
All which love is and does and can
Is all in all then.
Christina Georgina Rossetti
1431
Morning at last: there in the snow
Your small blunt footprints come and go.
Night has left no more to show,
Not the candle, half-drunk wine,
Or touching joy; only this sign
Of your life walking into mine.
But when they vanish with the rain
What morning woke to will remain,
Whether as happiness or pain.
Philip Larkin
1471
April is the cruellest month, breeding
Lilacs out of the dead land, mixing
Memory out of desire, stirring
Dull roots with spring rain.
Winter kept us warm, covering
Earth in a forgetful snow, feeding
A little life with dried tubers.
T.S. Eliot
The Waste Land
1476
To die, to sleep—
To sleep, perchance to dream, ay there’s the rub,
For in that sleep of death what dreams may come
When we have shuffled off this mortal coil,
Must give us pause; there’s the respect
That makes calamity of so long life.
William Shakespeare
Hamlet
1482
The greatest happiness of life is the conviction that we are loved—loved for ourselves, or rather, loved in spite of ourselves.
Victor Hugo
1488
To fear love is to fear life, and those who fear life are already three parts dead.
Bertrand Russell
1502
I must down to the seas again to the vagrant gypsy life.
To the gull’s way and the whale’s way where the wind’s like a whetted knife;
And all I ask is a merry yarn from a laughing fellow-rover,
And quiet sleep and a sweet dream when the long trick’s over.
John Masefield
Sea Fever

Life does not cease to be funny when people die any more than it ceases to be serious when people laugh.

When I can look Life in the eyes,
Grown calm and very coldly wise,
Life will have given me the Truth,
And taken in exchange—my youth.
Sara Teasdale
1544
Life has loveliness to sell,
All beautiful and splendid things,
Blue waves whitened on a cliff,
Soaring fire that sways and sings,
And childrens’s faces looking up
Holding wonder in a cup.

1588
As you go down the
Stream of life in your
Little canoe, I hope
You will have a jolley
Time, with plenty of
Room for two,
Love is to the human
Heart as sunshine is
To flowers, And friendship
Is the fairest thing in
This cold world of ours.

I do not want to believe that death is the gateway to another life. For me, it is a closed door. I do not say it is a step we must all take, but that it is a horrible and dirty adventure.

Yet the timeless in you is aware of life’s timelessness, and knows that yesterday is but today’s memory and tomorrow is today’s dream.

Alas! how easily things go wrong!
A sigh too much or a kiss too long,
And there follows a mist and a weeping rain,
And life is never the same again.

He who binds to himself a joy

William Blake
Eternity
1663
First follow Nature, and your judgment frame
By her just standard, which is still the same:
Unerring nature, still divinely bright,
One clear, unchanged, and universal light,
Life, force, and beauty must to all impart,
At once the source, and end, and test of art.
Alexander Pope
Essay On Criticism
1666
I want to fall in love with him again. I never stopped loving him - I've always loved him and always will - but our life together is verging on monotony. Love can withstand this, but for lust, it's fatal.
Paolo Coelho
Adultery
1667
So she had to satisfy herself with the idea of love - loving the loving of things whose existence she didn't care at all about. Love itself became the object of her love. She loved herself in love, she loved loving love, as love loves loving, and was able, in that way, to reconcile herself with a world that fell so short of what she would have hoped for. It was not the world that was the great and saving lie, but her willingness to make beautiful and fair, to live a once-removed life, in a world once-removed from the one in which everyone else seemed to exist.
Jonathan Safran Foer
Everything is Illuminated
1670
But I say to you that when you work you fulfil a part of earth's furthest dream, assigned to you when that dream was born,
And in keeping yourself with labour you are in truth loving life,
And to love life through labour is to be intimate with life's inmost secret.

Ensemble methods: Bagging and random forests

Mon 16-10-2017
Many heads are better than one.

We introduce two common ensemble methods: bagging and random forests. Both of these methods repeat a statistical analysis on a bootstrap sample to improve the accuracy of the predictor. Our column shows these methods as applied to Classification and Regression Trees.

Martin Krzywinski @MKrzywinski mkweb.bcgsc.ca
Nature Methods Points of Significance column: Ensemble methods: Bagging and random forests. (read)

For example, we can sample the space of values more finely when using bagging with regression trees because each sample has potentially different boundaries at which the tree splits.

Random forests generate a large number of trees by not only generating bootstrap samples but also randomly choosing which predictor variables are considered at each split in the tree.

Classification and regression trees

Mon 16-10-2017
Decision trees are a powerful but simple prediction method.

Decision trees classify data by splitting it along the predictor axes into partitions with homogeneous values of the dependent variable. Unlike logistic or linear regression, CART does not develop a prediction equation. Instead, data are predicted by a series of binary decisions based on the boundaries of the splits. Decision trees are very effective and the resulting rules are readily interpreted.

Trees can be built using different metrics that measure how well the splits divide up the data classes: Gini index, entropy or misclassification error.

Martin Krzywinski @MKrzywinski mkweb.bcgsc.ca
Nature Methods Points of Significance column: Classification and decision trees. (read)

When the predictor variable is quantitative and not categorical, regression trees are used. Here, the data are still split but now the predictor variable is estimated by the average within the split boundaries. Tree growth can be controlled using the complexity parameter, a measure of the relative improvement of each new split.

Individual trees can be very sensitive to minor changes in the data and even better prediction can be achieved by exploiting this variability. Using ensemble methods, we can grow multiple trees from the same data.

Personal Oncogenomics Program 5 Year Anniversary Art

Wed 26-07-2017

The artwork was created in collaboration with my colleagues at the Genome Sciences Center to celebrate the 5 year anniversary of the Personalized Oncogenomics Program (POG).

5 Years of Personalized Oncogenomics Program at Canada's Michael Smith Genome Sciences Centre. The poster shows 545 cancer cases. (left) Cases ordered chronologically by case number. (right) Cases grouped by diagnosis (tissue type) and then by similarity within group.

The Personal Oncogenomics Program (POG) is a collaborative research study including many BC Cancer Agency oncologists, pathologists and other clinicians along with Canada's Michael Smith Genome Sciences Centre with support from BC Cancer Foundation.

The aim of the program is to sequence, analyze and compare the genome of each patient's cancer—the entire DNA and RNA inside tumor cells— in order to understand what is enabling it to identify less toxic and more effective treatment options.

Principal component analysis

Thu 06-07-2017
PCA helps you interpret your data, but it will not always find the important patterns.

Principal component analysis (PCA) simplifies the complexity in high-dimensional data by reducing its number of dimensions.

Martin Krzywinski @MKrzywinski mkweb.bcgsc.ca
Nature Methods Points of Significance column: Principal component analysis. (read)

To retain trend and patterns in the reduced representation, PCA finds linear combinations of canonical dimensions that maximize the variance of the projection of the data.

PCA is helpful in visualizing high-dimensional data and scatter plots based on 2-dimensional PCA can reveal clusters.

`k` index: a weightlighting and Crossfit performance measure

Wed 07-06-2017

Similar to the `h` index in publishing, the `k` index is a measure of fitness performance.

To achieve a `k` index for a movement you must perform `k` unbroken reps at `k`% 1RM.

The expected value for the `k` index is probably somewhere in the range of `k = 26` to `k=35`, with higher values progressively more difficult to achieve.

In my `k` index introduction article I provide detailed explanation, rep scheme table and WOD example.
