Modeling Caffeine Metabolism
Caffeine is a stimulant drug that is widely consumed in tea, coffee, soda, and chocolate, among other beverages and foods. In this post, we construct a toy model for caffeine metabolism.
The mechanism of action of caffeine is complex, as is the process of developing tolerance. These are important factors to consider when thinking about the ultimate effect of the drug on alertness and we will discuss them briefly at the end.
So–let’s build our model. We need to consider caffeine input (consumption) and caffeine output (metabolism).
For our caffeine input, let’s conaider a semi-realistic model of consuming milligrams of caffeine as a single dose every hours. The simplifying assumptions associated with this model include the non-physical instant consumption of an entire source of caffeine under a rigid timeframe as well as neglecting the time needed for absorption within the body.
The instant consumption is not a terrible approximation since most sources are often consumed within 15 minutes or so. The rigid timefame is necessary to make the mathematics simple (as will be shown later), and is a more significant restriction. This model could not be used to consider someone who consumes a cup of coffee only at 9:00 am and 3:00pm every day, due to the periodic constraint on the caffeine input. This restriction imposes a constraing on the problems we can look at.
The assumption on the absorption of caffeine is a significant approximation. Typically, caffeine is absorbed through the intestine within 45 minutes of consumption with the peak blood caffeine content occuring between 1-2 hours after consumption. We have ignored these effects governing the bioavailability of caffeine. To justify this assumption, we can say that what our model is really looking at is the blood caffeine content with an instant input, i.e. instanteous absorption from the intestine into bioavailable forms that is time-shifted by some consistent amount after actual consumption. However, in a real system, there will be non-trivial dispersion of this input.
For our caffeine output (metabolism), we model the remaining active amount of the drug as an exponential decay with half-life 5.7 hours, based on the literature cited below. These assumptions are reasonable, given experimental data on caffeine content. Ignoring any prefactors, the significant tunable parameter for an exponential decay curve is the half-life (or equivalently, the time-constant). The half-life of caffeine in humans has been demonstrated to vary wildly depending on a variety of states of health. 5.7 hours is a reasonable mean value. The biochemistry underlying this decay is the degradation of caffeine into a number of other biomolecules, and follows first order kinetics.
We can now begin to put together our mathematical model.
First, the half-life of caffeine can be related to the time constant (for convenience) by
This gives our simple exponential decay for a single dose of mg at time as where gives the amount of metabolically active caffeine.
We can now evaluate a sum of these terms that are each time-shifted by the time of intake of caffeine. As a simple example, for caffeine consumption at and , we have
for all time since the second dose must be consumed for the equation to be valid.
For a more general sum at time , we need to sum the terms for all consumption events that have happened before . These events occur at time where is the largest multiple of that is less than or equal to . We find that . Thus, we can write our sum as a sum of these decaying exponentials, with the number of exponential terms equal to the number of consumption events that have occured:
We recognize the term within the summation to be a geometric series and replace the summation with the closed form sum.
We now have our closed form expression for the active caffeine content. A direct observation that we can make is that the consumption dose acts as a scalar multiplier over the entire function.
What can we do with this expression? Well, we can use it to model several profiles of caffeine consumption. I implemented the model in MATLAB. The caffeine function takes in a single time point, the caffeine content of the source , and the duration between consumptions events and returns the active caffeine amount at that time.
function [ content ] = caffeine( time, caffeineContent, durationBetween )
halfLife = 5.7;
tau = halfLife/log(2);
n = floor(time/durationBetween);
content = caffeineContent * exp(-time/tau) * (1-exp(durationBetween * (n+1)/tau))/(1-exp(durationBetween/tau));
end
The caffeineList function takes in a list of times, , and , and returns a list containing the active caffeine amounts at the times indicated by the input.
function [ content ] = caffeineList( time, caffeineContent, durationBetween )
content = zeros(1,length(time));
for i = 1:length(time)
content(i) = caffeine(time(i),caffeineContent,durationBetween);
end
end
The first thing we should do with this model is the trivial case of simulating a single dose. This acts as a sanity check to make sure that things look reasonable. This yields:
Cool! It looks like the model works on this trivial case. Now we can look at more interesting cases. The next example is a coffee-cup-equivalent every 24 hours.
We can now look at someone who drinks coffee twice a day. Unfortunately, we’re forced by our formalism to stick to doses that are 12 hours apart, which is perhaps not the most realistic model for how people consume coffee, but still perhaps worthwhile to look at.
Now, we look at frequent consumption of a smaller dose of caffeine. Our model here is four servings of 54 mg of caffeine, simulating the extreme consumption of four cans of soda per day.
Now we can think about the results a bit. First, the shape of the curves is entirely unsurprising–this is what a train of exponentials looks like. The result may be familiar from circuit theory.
We have two time-scales to look at: the steady-state and the transient.
The steady-state is perhaps more interesting, simulating the behavior of a habitutated drinker. We can see that in the case of 1 cup of coffee per day (figure 2), the caffeine content actually dips quite low before the next dose. However, when the drinker goes up to two cups per day (figure 3), they have a significant background level of active caffeine that is around 60 mg. This means that that much caffeine is constantly active in their bodies.
In the case of the transients, we can think of this as someone coming back to caffeine consumption after a long period without any consumption. The transition from no consumption to steady-state is perhaps clearest in figure 4. Here, we see the rise in background up to about 50 mg of always active caffeine (nearly a can of soda equivalent).
Remember, this is a toy model and shouldn’t be used for quantitative predictions. Qualitatively, we can clearly see that frequent consumption leads to a significant background level.
We can briefly consider the biological side of things. The mechanism of action of caffeine is to act as a competitive inhibitor on certain receptors within certain neurons. An increased background level of cafffeine means that the caffeine is constantly acting on these receptors as a competitive inhibitor. In a realistic biological system, this activity may change the profile of gene expression to increase receptor production, requiring more caffeine to result in the same effect, i.e. tolerance to a certain dosage of caffeine.
It is important to note that the relationship between our computed curves and complex physiological effects such as increased alertness is very complex. From our model, we really cannot say much with any certainty about this relationship, due to the complexity of the relationships between amounts of the drug, its biochemical activity, and its effect on behavior. There may be complex feedback regulation at multiple levels that makes this relationship complex and beyond the scope of this simple model.
To summarize: we have built a toy model for caffeine metabolism and used it to evaluate several different profiles of caffeine consumption, with a perspective towards the underlying biochemistry.

The word collaborate comes from Latin roots. Words beginning with the prefix col- mean together, implying doing something together. The root word laborare, also from Latin, gives us many of the English words used to talk about careers and work. In fact, the word labor comes from this root word. Putting the two Latin parts of this word together, the word literally means ‘to work together’.
Today, Collaboration is at the core of any artistic, curatorial, choreographic, literary or activist work, fundamentally transforming the ways in which we think of each of these fields of work both individually as well as collectively. Not even museum thinking, or thinking about museums as a form of critical artistic praxis can happen in isolation, and perhaps it is important to clarify that I write this not as an individual, but as a representative of a collective, a cultural center, a para-institution called ‘Museum of Impossible Forms’ (M{if}). Formed in 2017 and located in Kontula Helsinki, M{if} was borne out of a need for art and cultural spaces for artists and communities located in the margins. Now in its fourth year of working, it has metamorphosed into an indispensable resource within the multiple artistic, curatorial, activist and pedagogical discourses in Helsinki, Finland, and the Nordic region; and continues to make its presence felt as a decolonial, antiracist and queer-feminist project. As a heterogeneous space of unlearning, it has fostered experimental migrant forms of expression, norm-critical consciousness, and critical thinking through extensive programming towards building multiple vibrant communities within the tessellated folds of its space.
While this process of learning, unlearning, and re-learning at Museum of Impossible Forms has been made possible only by the potential generated through ‘multiple modes of working together’ that has allowed the Museum of Impossible Forms to in turn find its own socio-political and cultural location, these multiple modes of working together is a form of working that predates the formation of the space itself. For many of the members of the Museum of Impossible Forms, this work is a continuation of their own vision and practice, and for the hundreds of collaborators that have been a part of the M{if} journey as well as the thousands who have passed its doors, Museum of Impossible Forms strives to offer the not a platform or to give space, but rather to offer only the conditions for collaboration and the ‘encounter of equals’ as well as to sustain and strengthen them. But how do we outline these conditions for collaboration, for the creation of this cultural forum, where individual, sometimes professional, sometimes transgressive acts are played out; where people let their ‘real’ selves show – as a space of, for, and by the people? And who is ‘the people?
For the Museum of Impossible Forms, a relevant and uncompromising cultural space translates into the need for an actively updating ‘Safer Space Policy’ that can mould itself to operate between and beyond the conditions of conflict that surround us daily.
SAFE{R} SPACE
Why are Safer Spaces required?
Safer Spaces are sites that are senstive to modes and methods of individual and institutional discrimination, in their several normalised, normative and invisible forms, and seek to create environments that are supportive, non-threatening environment that encourages open-mindedness, respect, a willingness to learn from others, as well as physical and mental safety. They seek to prevent and prohibit the outbreak of discrimination. Every space must be a safer space, where “establishing guidelines for conditions that are not acceptable in a space, and action plan(s) for what one will do if those conditions arise, is part of being proactive in creating a safer space. Issues like hurtful language and behavior (both within the space itself, and in patterns extending beyond activities of the space), violence, touching people without their consent, intolerance of someone’s religious beliefs or lack thereof, as well as racist, ageist, sexist, heterosexist, transphobic, ableist, classist, [casteist,] sizeist, or exhibiting any other behavior or language that may perpetuate oppression”1 should be addressed with a safer space policy.
Safer Space can of course mean different things for different individuals and organisations; from seeking different forms of safety, and seeking safety from different things, safer spaces accordingly may change also depending on who constitutes them. Often a Safer space policy becomes the only enforceable tool of democratic governance for a grassroots organisation, especially ones that attempt to work on the basis of inclusion rather than exclusion.
For the Museum of Impossible Forms, the idea of being a ‘Safer Space’ is an idea that is in continuous evolution, and an important question of how our practice may be embedded, extended, and expanded beyond the activities of the space itself. It is about naming and thereby socially transforming histories of violence by creating spaces of agency, resistance, and the struggle for liberation. In this sense, a safer space is a form of learning that actively rejects dominant, privileged, exclusionary and violent forms of knowledge and acting, which we still often understand as education, and knowledge.
And so, it begins with asking that if a safer space is a policy that seeks to make a space safer, where does that space begin, and where does it end: Does the space of M{if} end at its doors, or spill out into the corridor, reach out till the front entrance of the building where many of our audience, participants and members enjoy an occasional smoke, or where they may have informal conversations that extend the program/me going on upstairs? Do its bounds extend to the Kontula Mall, its square, its parks, the restaurants and cafés we frequent, the Kierrätyskeskus (Recycling Center) where we buy most of the cutlery, or Saiturinpörssi, the shop downstairs that sells everything we may need for the space upstairs, or the various mix of markets that provide food for each of our events?
The question is not simply to determine jurisdiction but also to ascertain where does the quality of influence extend. Of course, while it may seem straightforward that the space outside the M{if} doors, and the corridors leading upto the space may be easy to oversee, or negotiate the semblance of authority when in majority, but is also apparent that further distance from the space itself causes a waning of the safer space policies’ authority. The credibility of a safer spaces policy is inversely proportional to the distance from where a safer space policy is issued.
If the relevance of Museum of Impossible Forms is to situate itself as “facilitating the process of transgressing the boundaries/borders between art, politics, practice, theory, the artist and the spectator,”2 then the tools of facilitating this transgressing must extend beyond the boundaries of its own space, one that allows a sphere of influence to reach out further, beyond Kontula, beyond Helsinki and Finland, beyond the Nordic, beyond… er, the beyond?
‘It is the trope of our times to locate the question of culture in the realm of The ‘ Beyond’3 – ‘at or to the further side of’, further both in time and space, past and future, over and under, before and after, arrival and departure. Beyond defines the limits, as being ‘outside the range of, beyond the power/capacity of, outside the limitations of, surpassing’, or as a superlative, as in ‘greater than, more than, exceeding, in excess of, above, over and above, above and beyond, upwards of’ as well as the unknown. The ‘beyond’ is neither a new horizon, nor a leaving behind of the past4, for Homi Bhabha, the present now does not signify the break with the past or a bond with the future, but has a synchronic presence, the moment of transit where space and time cross to produce complex figures of difference and identity, past and present, inside and outside, inclusion and exclusion. For there is a sense of disorientation, a disturbance of direction, in the ‘beyond’: an exploratory, restless movement caught so well in the French rendition of the words au-delà – here and there, on all sides, fort/da, hither and thither, back and forth.
‘Beyond’ signifies spatial distance, marks progress, promises the future; but our intimations of exceeding the barrier or boundary – the very act of going beyond – are unknowable, unrepresentable, without a return to the ‘present’. Being in the ‘beyond’, then, is to inhabit an intervening space. In the spirit of inhabiting the intervening spaces, a space between pre- and post- COVID-19, a of physical distancing and social solidarity, a space of finding new methods of collaboration, I propose that we re-configure the ways in which we understand space itself.
SAFE{R} PEOPLE
In the context of socio-political thought, if the walls of the house are the first and the basic unit or cell of society, it is also its most fundamental division – the house protects and gives security and privacy, from others. This means that it is a contingent grouping – by creating the grouping of a ‘family’, one is also automatically creating another group, ‘non-family’. Moving from this agrarian construct of the wall, further divisions and groupings may be extrapolated, into the compound wall, the locality, the suburb, city, district, state, nation, continent, planet, solar system, galaxy, the known universe... one’s choice, if it were possible to make such a choice, would ideally be dependent on one’s own comfort with the level of contingency. At which stage do we choose to exclude, to perform the inevitable act of exclusion? At which stage do we define ‘We, the People’? An almost Kafkaesque transmogrification connects the prehistoric past to sci-fi future. “Who really are ‘the people’? And what operation of discursive power circumscribes ‘the people’ at any given moment, and for what purpose?”5
What distinguishes the political from a civil society is that “the discourse of citizen’s rights must translate into a preemptive commitment to radical change”.6 This change is in the stark light of a reality where the rifts between power structures and the subjugated have not decreased; neither have the gaps between class distinctions. Rather, we are in a contemporary world that today has created new levels of precarity – the useless class, the refugee class, and in contrast a new kind of human being – “the kind that are put in concentration camps by their foes and in internment camps by their friends”7. Today, where we do not wall others in, we wall them out. The state of fellow-imprisonment is paramount.
How does collaboration work in these circumstances, and what do words such as solidarity mean – How do acts and expressions of individuality curb our synchronisation with others? And Why?
This is the fundamental question of Classical Social Theory, as it developed in Europe, started out from the experience of alienation, and its development accompanied successive transpositions of alienation to higher levels of mediation shaping cultural, social, political, economic, legal and educational processes and institutions. The concept of alienation is deeply embedded in all the major religions as well as the social and political theories of the civilised epoch, the idea that some time in the past people lived in harmony, and then there was some kind of rupture which left people feeling like foreigners in the world, that sometime in the future this alienation would be overcome and humanity would again live in harmony with itself and Nature. But this utopian desire of consensus8 is at odds with the world we have cultivated, one that leaves us all experiencing the Perpetual Foreigner Syndrome9 . It is imperative for us to go beyond it now, through the mode of sympathetic critique. We now need new cartography based on the mapping of continents of affinities, and a search for commonalities based on jointly faced crises and shared predicaments; to move beyond static Safer Spaces, to becoming ‘Safer People’.
Whatever Museums may not do, it must do this – It must be unflinchingly cognizant of our differences, our diversity, our plurality; but it must also highlight our affinities, our intersections, our togetherness – in order to counter alienation by providing spaces for familiarisation. Familiarisation is the key function for the Museum of today, the act of familiarising ourselves to each other is the crucial task we face. Through it we present ourselves “[…] only as members of a biological species which has a remarkable history, and whose disappearance none of us can desire”10, rather than as beings who present themselves to each other as unrecognisable aliens, self censored and segregated into claims of uniqueness and markers of identity that can have no ultimate meaning.

For some time now, Typed Racket has unsoundly type checked prefab structs. This bug been fixed for the Racket v7.0 release (for more info, see the relevant Typed Racket RFC and the illustrative examples in the Prefab section of the docs). If you suspect your prefab-utilizing Typed Racket code no longer type checks because of this fix, we hope the below instructions help make any necessary changes as painless as possible. We apologize for any inconvenience. If you believe there are issues/fixes that should be added to this list, please do let us know.
Consider the following prefab struct definition:
(struct point ([x : Number] [y : Number]) #:prefab)
Previously (Racket versions prior to 7.0) the following would type check:
(: sum-point (-> Any Number)) (define (sum-point p) (cond [(point? p) (+ (point-x p) (point-y p))] [else (error "not a point! ~a" p)]))
However, in Racket 7.0 and beyond, Typed Racket will complain with the following error messages:
Type Checker: type mismatch expected: Number given: Any in: (point-x p) Type Checker: type mismatch expected: Number given: Any in: (point-y p)
This is because point?
only tests if the value
is a prefab structure with key 'point
and has 2
fields and says nothing about the contents of the fields.
In other words, point?
is a predicate for the
type (Prefab point Any Any)
(if the prefab is
immutable). If point
were a mutable prefab
struct, the predicate would be for the type (PrefabTop point
2)
, which is a type for a prefab that can be read from, but
not written to (since we do now know what type to enforce
for the mutable fields).
Fixes for this could involve any of the following:
Manually testing the values produced by (point-x p)
and
(point-y p)
with number?
is one
(perhaps verbose) way to fix the issue.
You can test the fields directly:
(: sum-point (-> Any Number)) (define (sum-point p) (cond [(and (point? p) (number? (point-x p)) (number? (point-y p))) (+ (point-x p) (point-y p))] [else (error "not a valid point! ~a" p)]))
Or you can let bind them and then test them:
(: sum-point (-> Any Number)) (define (sum-point p) (cond [(point? p) (let ([x (point-x p)] [y (point-x p)]) (if (and (number? x) (number? y)) (+ x y) (error "not a valid point! ~a" p)))] [else (error "not a valid point! ~a" p)]))
You can define a predicate for the type which includes the field types (as long as the field types are 1st order):
(define-predicate valid-point? point) (: sum-point (-> Any Number)) (define (sum-point p) (cond [(valid-point? p) (+ (point-x p) (point-y p))] [else (error "not a valid point! ~a" p)]))
or equivalently you can define the predicate with an
explicit Prefab
type if you prefer (the
two are equivalent):
(define-predicate valid-point? (Prefab point Number Number))
One downside to using define-predicate
with a prefab
type is that it will only work in Racket versions >= 7.0. If
you would like to use this solution but in a way that is
also compatible with previous versions of Racket, you
can install the prefab-predicate-compat
package (e.g. raco pkg install prefab-predicate-compat
)
and use the following form:
(define-backwards-compatible-flat-prefab-predicate valid-point? point)This macro inspects the version of Racket which is being used and expands to code that will compile fine in both. In other words, in Racket versions prior to 7.0, it expands into the following:
(define valid-point? point?)which is clearly the same as just using the (unsound) predicate
point?
in versions.
For versions 7.0 and on it expands into this:
(define-predicate valid-point? point)
define-predicate
uses a flat contract as a
predicate. If you're concerned with the performance, it
may be worthwhile to define a manual predicate:
(: valid-point? (-> Any Boolean : point)) (define (valid-point? p) (and (point? p) (number? (point-x p)) (number? (point-y p))))
Manually defining predicates can sometimes be a little bit tricky, FYI.
Another alternative is to use more specific types so that, even
though the predicate point?
doesn't test
the values in the fields, it is enough information to
determine the value is indeed a point
(equivalently (Prefab point Number Number)
).
This will work well when you know the value is either
a point
or some other value which is not
a (Prefab point Any Any)
:
(: sum-point (-> (U point False) Number)) (define (sum-point p) (cond [(point? p) (+ (point-x p) (point-y p))] [else (error "not a point! ~a" p)]))
I.e. we changed the domain from Any
to
(U point False)
, and with that type for
the domain, point?
returning #true
tells us indeed the fields are numbers since the type point
is equivalent to (Prefab point Number Number)
.
The previous example (i.e. sum-point
) could also
be nicely written using Racket's match
macro:
(define (sum-point p) (match p [(point x y) (+ x y)] [_ (error "not a valid point! ~a" p)]))
That would have type checked prior to the 7.0 Racket
release. However, for the same reason the manual
predicate version breaks, this too will break (i.e.
there are no tests for the fields x
and y
).
In this case, adding predicates for the field patterns is probably the easiest solution:
(: sum-point (-> Any Number)) (define (sum-point p) (match p [(point (? number? x) (? number? y)) (+ x y)] [_ (error "not a valid point! ~a" p)]))
Restricting the domain of the function itself (as the previous section describes) may also solve the issue.
All field accessors and mutators are now polymorphic. This is because they work on any value which is the particular prefab, regardless of the values the fields contain.
Unfortunately, this means that some code which used to type check prior to version 7.0:
(: add-xs (-> (Listof point) Number)) (define (add-xs ps) (apply + (map point-x ps)))
will now fail to type check because Typed Racket's type inference fails to recognize some combinations of polymorphic operations. E.g., the above example will not error with the following message:
Type Checker: Bad arguments to function in `apply': Domains: (#(struct:Rest (Number)))* Arguments: (Listof Any) in: (apply + (map point-x ps))
Mousing over the expression (map point-x ps)
in
DrRacket indicates it was assigned type (Listof
Any)
, which is not a argument for (apply +
...)
.
This can be fixed by manually instantiating point-x
:
(: add-xs (-> (Listof point) Number)) (define (add-xs ps) (apply + (map (inst point-x Number) ps)))
Or a monomorphic version of point-x
could be
defined (i.e. a non-polymorphic version which expects a
(Prefab point Number Number)
and returns
a Number
).

NOBLEMAN: Now this is what I call workmanship. There is nothing on earth more exquisite than a bonny book, with well-placed columns of rich black writing in beautiful borders, and illuminated pictures cunningly inset. But nowadays, instead of looking at books, people read them. A book might as well be one of those orders for bacon and bran that you are scribbling. -- Saint Joan, Scene IV
George Bernard Shaw, 1924
Font creation
First create a new font with the New
command in the File
menu (or by using the -new argument at startup).
Give the font a name with the Font Info
command from the Element
menu. You use this same command to set the copyright message and change the ascent and descent (the sum of these two determines the size of the em square for the font, and by convention is 1000 for postscript fonts, a power of two (often 2048 or 4096) for truetype fonts and 15,000 for Ikarus fonts). (Also if you are planning on making a truetype font you might want to check the Quadratic Splines checkbox to use the native truetype format. Editing is a little more difficult in this mode though)
You may also wish to use Encoding->Reencode to change what characters are available in your font. FontForge generally creates new fonts with an ISO-8859-1, which contains (most of) the characters needed for Western Europe (the latin letters, some accented letters, digits, and symbols).
Creating a glyph
Once you have done that you are ready to start editing glyphs. Double click on the entry for "C" in the font view above. You should now have an empty Outline Glyph window:
The outline glyph window contains two palettes snuggled up on the left side of the window. The top palette contains a set of editing tools, and the bottom palette is for managing drawing layers. They can be added, deleted (not all!), shown or hidden, for example.
Cubic layers (C) use third-order Bezier splines, like PS fonts. Quadratic ones (Q) use second-degree splines, that are harder to edit, but mathematically easier and simpler to control, so they are used in TTF fonts.
The foreground (F) layer contains the outline that will become part of the font. The background (B) layer can contain images or line drawings that help you draw this particular glyph. The guide (#) layer contains lines that are useful on a font-wide basis (such as the x-height). Currently all layers are empty.
This window also shows the glyph's internal coordinate system with the x and y axes drawn in light grey. A line representing the glyph's advance width is drawn in black at the right edge of the window. FontForge assigns an advance width of one em (in PostScript that will usually be 1000 units) to the advance width of a new glyph.
Let us assume you already have a bitmap image of the glyph you are working on. Select the Import command from the File menu and import that image. It will be scaled so that it is as high as the em-square.
Select the background layer as editable from the layers palette, move the mouse pointer to one of the edges of the image, hold down the shift key, depress and drag the corner until the image is a reasonable size, then move the pointer onto the dark part of the image, depress the mouse and drag until the image is properly positioned.
If you have downloaded the autotrace program you can invoke Element->AutoTrace
to generate an outline from the image. But if you have not you must add points yourself. Change the active layer to be the foreground, and go to the tools palette and select the round (or curve) point. Then move the pointer to the edge of the image and add a point. I find that it is best to add points at places where the curve is horizontal or vertical, at corners, or where the curve changes inflection (A change of inflection occurs in a curve like "S" where the curve changes from being open to the left to being open on the right. If you follow these rules hinting will work better.
It is best to enter a curve in a clockwise fashion, so the next point should be added up at the top of the image on the flat section. Because the shape becomes flat here, a curve point is not appropriate, rather a tangent point is (this looks like a little triangle on the tools palette). A tangent point makes a nice transition from curves to straight lines because the curve leaves the point with the same slope the line had when it entered.
At the moment this "curve" doesn't match the image at all, don't worry about that we'll fix it later, and anyway it will change on its own as we continue. Note that we now have a control point attached to the tangent point (the little blue x). The next point needs to go where the image changes direction abruptly. Neither a curve nor a tangent point is appropriate here, instead we must use a corner point (one of the little squares on the tools palette).
As you see the old curve now follows the image a bit more closely. We continue adding points until we are ready to close the path.
Then we close the path just by adding a new point on top of the old start point
Now we must make the curve track the image more closely, to do this we must adjust the control points (the blue "x"es). To make all the control points visible select the pointer tool and double-click on the curve and then move the control points around until the curve looks right.
Finally we set width. Again with the pointer tool, move the mouse to the width line on the right edge of the screen, depress and drag the line back to a reasonable location.
And we are done with this glyph.
If you are mathematically inclined you may be interested in the coordinates that fontforge shows in the upper left of the window. Generally you can draw glyphs quite happily without bothering about these, but for those who are interested here is some basic info:
- Each glyph has its own coordinate system.
- The vertical origin is the font's baseline (the line on which most latin letters rest)
- The horizontal origin is the place where drawing the glyph will commence. In the example above what gets drawn initially is empty space, that is fairly common, and that empty space (the distance from the origin to the left edge of the glyph) is called the left side bearing.
- The units of the coordinate system are determined by the em-size of the font. This is the sum of the font's ascent and descent. In the example above the font's ascent is 800 and descent is 200, and the ascent line (the one just above the top of the "C") is 800 units from the baseline, while the descent line is 200 units below.
- So a position of 282,408 (as above) means that the cursor is 282 units right of the horizontal origin and 408 units above the baseline (or roughly halfway between baseline and ascent).

In previous episodes we took a look at the basics of ARM Templates, and some of the methods of developing ARM Templates. In this installation, we’ll take a look at common deployment options.
Deployment Strategy
When it comes to determining a standard deployment strategy for ARM Templates, there are a number of options, but the goal is to choose a strategy that fits the audience and situation. In certain circumstances it might make sense to mix and match these options to fit our overall deployment strategy.
To help with this decision, I’ve created a flowchart based on my own experiences and personal opinions:
Deployment Concepts
Resource Groups
Templates are always deployed to a Resource Group, and Resource Groups cannot be created via ARM Templates. This means that the target Resource Group must exist prior to template deployment.
Template Validation
Prior to deploying a template, we can validate the template code to ensure there are no syntax errors or missing values. This is done by default when deploying templates through the Azure portal, but this can also be done via PowerShell.
Test-AzureRmResource Group Deployment
Deployment Mode
Templates can be deployed in “incremental” or “complete” modes. The default deployment mode is incremental, specifying that the resources deployed to the target Resource Group are incremental changes or additions to the Resource Group. In contrast, when deploying in complete mode, we are specifying that the template deployment is the desired final state for the target Resource Group, and resources that exist in the target Resource Group that are not defined by the template will be removed. Utilizing complete mode should be used only when specifically needed as this can result in resource loss.
Azure Portal Resource Deployment
One-time ARM Template deployments can be achieved by creating a new “Template deployment” resource within the Portal. It can be a valuable tool if we just want to test something out, but prevents us from easily redeploying, reusing, or managing our templates.
Within the “Template deployment”, we can start with a sample or build our own custom template.
Here we can paste in the contents of our template, generally this consists of the “azuredeploy.json” contents.
After saving the template, we can input our parameters for the template deployment and then just click “Purchase” to deploy.
PowerShell
For those comfortable with PowerShell, deploying templates via PS scripts is fairly easy and there are some great methods to handle template deployment via PowerShell.
The first option is to utilize the “New-AzureRmResourceGroupDeployment” script which provides the ability to reference a template and parameters file to be deployed to Azure. We can even append “-Mode (complete or incremental)” to specify our desired deployment mode. In the following example, a mode is not specified, resulting in the use of “incremental” mode.
The previous script is fairly easy to use and doesn’t require much input, but there is another deployment script that provides much more flexiblity. Within the “Azure QuickStart Templates” repository, there’s a provided script Deploy-AzureResourceGroup, which will do things like validate the template prior to deployment and create a new Resource Group if the one referenced doesn’t exist.
Templates Blade
The “Templates” blade within the Azure Portal is currently a preview feature that provides the ability to store, share, and deploy commonly used templates. This is a great method for easily creating common resources as an alternative to Azure Marketplace resources. For members of the team who aren’t working with ARM Templates on a regular basis but need to deploy a standardized resource, the Templates Blade is a great option. The biggest drawbacks of this method are the inability to easily nest or reference parameters files.
When creating a new template, a name and description are provided to specify the templates purpose or additional details.
Now we’ll just paste in the code that’s stored in our “azuredeploy.json” file containing our resource definitions. We’ll click “OK” and “Add”.
The template will show up under the Templates blade and is available for deployment.
At the top of the Template, we’ll click the “Deploy” button.
After clicking “Deploy”, we receive the friendly parameters page that will allow us to input the parameter values for deployment.
Visual Studio
Visual Studio can be an extremely powerful tool for handling ARM Templates. We can develop, manage with source control, and deploy, our ARM Templates all within the same tool. The graphical interfaces used during the deployment process can help prevent copy/paste errors that may occur when deploying via PowerShell and we get the full value of specifying predefined parameter files.
To deploy a template in Visual Studio, we’ll start by creating a new project.
The Azure Resource Group project type can be found under “Visual C#” > “Cloud”. We’ll provide a name for our project and click “OK”.
After creating our new project, a second interface will allow us to choose which template we’d like to start with. In this case, we already have the code we want to use so we’ll just choose “Blank Template”.
Now all we have to do is copy our template files into our new Visual Studio project. Once we have the template files added to the project, we can right-click on our Visual Studio project and click “Deploy”, and select “New…”.
The deployment interface allows us to choose the Subscription, Resource Group, and our Template and Parameters file. This is a really nice feature when we have multiple parameters files stored in the project and want to easily select the appropriate parameters file rather than copy/pasting or typing them out into a PowerShell deployment script.
Deploy to Azure
Azuredeploy.net is a great tool to easily deploy ARM Templates from a public GitHub repository to your Azure environment. Azuredeploy.net cannot be used for private GitHub repositories and for this reason doesn’t make sense for an organization’s use. However, this is great feature for publicly shared templates, allowing others to easily deploy a template into their own Azure environment. In this case, we can navigate to the Cooper’s Cloud GitHub repository and deploy this N-Tier template into any Azure Subscription with the click of a button.
To add the “Deploy to Azure” button within a public GitHub repository, a README.md file is added to the repository containing the following string:
[![Deploy to Azure](https://azuredeploy.net/deploybutton.png)](https://azuredeploy.net/) ![image alt text](/assets/img/AzureDeploy.png)


Name can't be blank, and can only contain lowercase letters and numbers.
A repository with this name already exists, view it here.


Polarity
: whether the word can be or is negated
There is no word for “yes” or “no” in Irish. Instead, a negative particle is used in combination with the verb to give a negative polarity.
Neg
: negative
The negative particle ní* can be used in almost every tense, except the past. It causes lenition to relevant consonants (see Form), otherwise there is no change. In the past tense the particle is written as níor, and does not trigger any further lenition, though the word may already be lenited due to past tense morphology (see Tense).
*In the Ulster dialect, this particle also appears as cha (see Dialect)
Examples
- Ní thuigim “I don’t understand”
- Níor ól sé “He didn’t drink”
The interrogative negative particle nach is used to pose a negative question, or to introduce a clausal complement (see PartType).
Examples
- Nach bhfuil tú? “Aren’t you?”
- Dhaoine nach ndearna scannán riamh “People who haven’t ever made a film”
The verb “to be” (in Irish bí) is given the negative form níl in the present tense, as a contraction of ní bhfuil. It can inflect to show (for instance) person.
Examples
- Níl sé sin mí-réasúnta “That is not unreasonable”
- Ach nílirse sásta “But you aren’t happy”
Polarity in other languages: [bej] [bg] [bm] [cs] [el] [et] [fi] [fr] [ga] [gd] [gub] [hy] [jaa] [ky] [pcm] [qpm] [ru] [sl] [sv] [tr] [tt] [u] [uk] [urj]

Fortnite star Ninja claims Epic Games was 'too heavy-handed' with ban of Brit teen
Ninja has leapt to FaZe Jarvis' defence, after the youngster was banned from Fortnite for cheating in the popular game
by Shivali Best, https://www.facebook.com/shivalibestjournalist/He’s one of the biggest names in the gaming industry, and now Fortnite star Ninja has waded into the debate of whether Jarvis Kaye should have been banned from Fortnite.
Jarvis, known as FaZe Jarvis, broadcast a video of him using ‘aimbots’ - a tactic that is banned on Fortnite - to his two million YouTube subscribers.
Epic Games, the developer behind Fortnite, immediately banned Jarvis from the game, sparking a fierce debate of whether cheating should result in a permanent ban.
Now, Ninja has leapt to Jarvis’ defence, claiming that Epic Games’ punishment was ‘too heavy-handed.’

“It wasn’t a tournament, wasn’t a Cash Cup, it should be maybe a six-month ban from competitive. Permanent though?”
Jarvis has over two million subscribers on YouTube, who regularly tune in to see the youngster playing Fortnite.
Ninja claims that this large following should be a reason for Epic Games not to permanently ban him.
He added: “Without your content creators, there’s a negative impact on your game.
 What else is he going to play?
“He has to transition over from one of the most popular games, and one that’s made him skill-wise, and career-wise, and now he has to play another game.”
Ninja also drew comparisons with YouTuber Logan Paul, who drew controversy last year for point g a video showing dead bodies in Japan’s ‘Suidcide Forest’.
He said: “Logan Paul literally filmed someone hanging in a forest and his channel didn’t get banned and he’s been perfectly fine.
“In that aspect, he was a YouTuber, a big one, and he didn’t get banned. YouTube decided that he was big enough to not get banned.”
Mirror Online has contacted Epic Games for comment.

dropdb - remove a PostgreSQL database
dropdb [connection-option...] [option...] dbname
dropdb destroys an existing PostgreSQL database. The user who executes this command must be a database superuser or the owner of the database.
dropdb is a wrapper around the SQL command DROP DATABASE (DROP_DATABASE(7)). There is no effective difference between dropping databases via this utility and via other methods for accessing the server.
dropdb accepts the following command-line arguments:
dbname
Specifies the name of the database to be removed.
-e
--echo
Echo the commands that dropdb generates and sends to the server.
-i
--interactive
Issues a verification prompt before doing anything destructive.
-V
--version
Print the dropdb version and exit.
--if-exists
Do not throw an error if the database does not exist. A notice is issued in this case.
-?
--help
Show help about dropdb command line arguments, and exit.
dropdb also accepts the following command-line arguments for connection parameters:
-h host
--host=host
Specifies the host name of the machine on which the server is running. If the value begins with a slash, it is used as the directory for the Unix domain socket.
-p port
--port=port
Specifies the TCP port or local Unix domain socket file extension on which the server is listening for connections.
-U username
--username=username
User name to connect as.
-w
--no-password
Never issue a password prompt. If the server requires password authentication and a password is not available by other means such as a .pgpass file, the connection attempt will fail. This option can be useful in batch jobs and scripts where no user is present to enter a password.
-W
--password
Force dropdb to prompt for a password before connecting to a database.
This option is never essential, since dropdb will automatically prompt for a password if the server demands password authentication. However, dropdb will waste a connection attempt finding out that the server wants a password. In some cases it is worth typing -W to avoid the extra connection attempt.
--maintenance-db=dbname
Specifies the name of the database to connect to in order to drop the target database. If not specified, the postgres database will be used; if that does not exist (or is the database being dropped), template1 will be used.
PGHOST
PGPORT
PGUSER
Default connection parameters
This utility, like most other PostgreSQL utilities, also uses the environment variables supported by libpq (see Section 31.14, (lqEnvironment Variables(rq, in the documentation).
In case of difficulty, see DROP DATABASE (DROP_DATABASE(7)) and psql(1) for discussions of potential problems and error messages. The database server must be running at the targeted host. Also, any default connection settings and environment variables used by the libpq front-end library will apply.
To destroy the database demo on the default database server:
$ dropdb demo
To destroy the database demo using the server on host eden, port 5000, with verification and a peek at the underlying command:
$ dropdb -p 5000 -h eden -i -e demo Database "demo" will be permanently deleted. Are you sure? (y/n) y DROP DATABASE demo;
createdb(1), DROP DATABASE (DROP_DATABASE(7))

A THOUSAND ACRES(Touchstone/Buena Vista)Directed by Jocelyn Moorhouse The film adaptation of Jane Smiley's Pulitzer Prize-winning "A Thousand Acres" works so hard to pack as much of the book into an hour and 45 minutes that it feels like the highlights tape pulled from several months of a daytime soap-opera. Incest, lawsuits, broken marriages, impulsive affairs, senility, cancer, suicide: They're all present and accounted for. You'll barely have time to weep over one crisis before an even worse one pops up. But at the heart of this sometimes strident movie are two magnificent performances, which redeem everything that surrounds them. As the relentlessly downbeat and vengeance-hungry Rose, Michelle Pfeiffer all but breathes fire.  When Pfeiffer challenges her husband (Kevin Anderson) after a ruined game of Monopoly, it's a scene Bette Davis would have come back from the grave to play. Equally "wow"-worthy is Jessica Lange as the serene, industrious Ginny, whose perpetual happy face finally cracks and disintegrates. Few actresses give themselves over to a role as thoroughly as Lange does: She leaps into the pit at the bottom of Ginny's soul, unafraid of where she'll land. Playing off the equally determined Pfeiffer seems to sharpen her instincts even more; plenty of sparks fly before the finale. Laura Jones's screenplay sometimes short-sells the novel's themes and its' characters' motivations, but the priviledge of watching two of America's finest leading ladies scaling new dramatic heights is reason enough to put "Acres" on your must-see list.

This is your awesome new webpage template. You can always find this starter template in the SIP Student Unit 3 repository.


Player
During this tutorial we’ll create interfaces for Actors and for Drawing things. We’ll then create a simple Player class that implements both of our new interfaces. We’ll draw the Player and his field of view to the screen but we will not get into accepting keyboard input and moving the Player until next time.
Creating the Interfaces
There are two new interfaces that we want to create. In C# interfaces are used to define a set of functionality or a group of related behaviors. You can think of them as a contract that classes must follow. By implementing the interface a Class is agreeing to the contract and must implement those methods and behaviors. We will always prefix our interfaces with the letter ‘I’ as is common in C#.
IActor Interface
The first interface we will create will be IActor
. For now it will only have two properties, Name
and Awareness
. The Awareness
property will be used when calculating field-of-view to determine the maximum distance the Actor is aware of, can see or sense.
Create a new folder called Interfaces
and then create a new interface in the folder called IActor.cs
. Place the following code inside the new file.
namespace RogueSharpV3Tutorial.Interfaces
{
public interface IActor
{
string Name { get; set; }
int Awareness { get; set; }
}
}
IDrawable Interface
The next interface we will define will be IDrawable
. The properties that we need to draw a cell in the console are a Color
, Symbol
, and the X
and Y
coordinates of the cell. We also want to have a Draw
method that will take the RLConsole
to draw to as well an IMap
. Notice that we don’t require a concrete Map
class but we will accept any class that follows the IMap
contract. The IMap
is important because that will allow us to calculate field-of-view.
namespace RogueSharpV3Tutorial.Interfaces
{
public interface IDrawable
{
RLColor Color { get; set; }
char Symbol { get; set; }
int X { get; set; }
int Y { get; set; }
void Draw( RLConsole console, IMap map );
}
}
Actor Base Class
Now that we have defined our interfaces we’ll make a base class called Actor that implements both of our interfaces. In C# a class can only inherit from a single class. It can however implement as many interfaces as you want.
Start by creating a new class in the Core
folder called Actor.cs
. It should implement both IActor
and IDrawable
. Place the following code in Actor.cs
:
public class Actor : IActor, IDrawable
{
// IActor
public string Name { get; set; }
public int Awareness { get; set; }
// IDrawable
public RLColor Color { get; set; }
public char Symbol { get; set; }
public int X { get; set; }
public int Y { get; set; }
public void Draw( RLConsole console, IMap map )
{
// Don't draw actors in cells that haven't been explored
if ( !map.GetCell( X, Y ).IsExplored )
{
return;
}
// Only draw the actor with the color and symbol when they are in field-of-view
if ( map.IsInFov( X, Y ) )
{
console.Set( X, Y, Color, Colors.FloorBackgroundFov, Symbol );
}
else
{
// When not in field-of-view just draw a normal floor
console.Set( X, Y, Colors.Floor, Colors.FloorBackground, '.' );
}
}
}
Implementing the properties should be straightforward. They just have public getters and setters. The most interesting part will be the Draw() method because it needs to inspect the IMap for explored cells and cells in field-of-view so that it can draw the appropriate symbols.
Player Color
We need to establish a Color
for our Player
. Open Colors.cs
and add the following line:
public static RLColor Player = Swatch.DbLight;
Player Class
It’s time to create the Player
class. In the Core
folder make a new class called Player.cs
. We want it to have a base class of Actor
so that it will automatically get the Draw()
method and all the necessary properties. The code should look like this.
namespace RogueSharpV3Tutorial.Core
{
public class Player : Actor
{
public Player()
{
Awareness = 15;
Name = "Rogue";
Color = Colors.Player;
Symbol = '@';
X = 10;
Y = 10;
}
}
}
You’ll see that all we have to do to make the Player
unique from other Actor
s is to define unique values for our properties. In this case the Player
can see 15 cells so the Awareness
is 15. We’re also setting the starting position to 10, 10 and the Color
to the one we defined earlier. The Symbol
is the standard ‘@’ character from the original Rogue. Feel free to adjust any of these values to anything you want.
If you’ve been following along with the tutorial your project structure should now look like this:
Player Field-of-View Method
Open DungeonMap.cs
and create a new method called UpdatePlayerFieldOfView()
which will be called when we position the Player
// This method will be called any time we move the player to update field-of-view
public void UpdatePlayerFieldOfView()
{
Player player = Game.Player;
// Compute the field-of-view based on the player's location and awareness
ComputeFov( player.X, player.Y, player.Awareness, true );
// Mark all cells in field-of-view as having been explored
foreach ( Cell cell in GetAllCells() )
{
if ( IsInFov( cell.X, cell.Y ) )
{
SetCellProperties( cell.X, cell.Y, cell.IsTransparent, cell.IsWalkable, true );
}
}
}
Adding the Player to the Game
The last thing that we have to do in this tutorial is add the Player
to the Game
. Open Game.cs
and add a Player
property just above our existing DungeonMap
property.
public static Player Player { get; private set; }
Next we need to construct a new Player
in our Main()
method. Don’t forget to update the field-of-view by calling DungeonMap.UpdatePlayerFieldOfView()
.
Player = new Player();
// The next two lines already existed
MapGenerator mapGenerator = new MapGenerator( _mapWidth, _mapHeight );
DungeonMap = mapGenerator.CreateMap();
// End of existing code
DungeonMap.UpdatePlayerFieldOfView();
We’re almost done. The last thing we need to do is call Player.Draw()
in our OnRootConsoleRender()
method.
Player.Draw( _mapConsole, DungeonMap );
If all went well when you start your game you should see this:

The parking API provides real-time parking data from both the City of Madison Parking Utility and the UW Transportation Service. In addition to lot availability, API consumers can include current or future special events for a given lot which aides in detecting potential changes to the lot's payment policy.
| Name | Value | Required | Description |
|---|---|---|---|
| expand | specialevents | No | If "expand=specialevents" is included as a query string parameter, any current or future special event(s) that apply to a given lot will be embedded in the lot payload as members of the specialEvents collection. |

Special event information and pricing policies vary between city and UW operated lots making it difficult to provide a consistent, intuitive return payload across the two operators. UW makes it worse by having a dizzying array of pricing policies depending on the event type. The API had to take the simplest approach possible and push the complexity down to the API consumer (highly unfortunate).
In addition to pricing complexity, UW does not provide parkingStartDatetime and parkingEndDatetime, which makes explicit determination of special event windows impossible. To mitigate the following steps were taken:

Kali Linux ARP Spoofing
In computer networking, ARP spoofing, ARP cache poisoning, or ARP poison routing, is a technique by which an attacker sends (spoofed) Address Resolution Protocol (ARP) messages onto a local area network.
ARP
The Address Resolution Protocol (ARP) is a communication protocol used for discovering the link layer address, such as a MAC address, associated with a given internet layer address, typically an IPv4 address.
Check ARP on Linux/Mac/Win.
arp -a
Find Default Gateway
Check your default gateway:
ip route
Scan the Network
-r is for range

Detection of Bike-riders
This involves detection of bike-riders in a frame and then uses objects, the potential bike-riders returned by
background modeling step and classify them as ‘bike-rider’
vs ‘others’, based on their visual features. It involves
two steps: feature extraction and classification.
After feature extraction, next step is to
classify them as ‘bike-riders’ vs ‘other’ objects. This
requires a binary classifier.
