How to use this GPA Calculator:
- On the Intro screen, select your institution.
- Check the level(s) and semester(s) that you want to calculate for.
- Click Proceed.
- On the SemestersSetup screen, enter the number of courses you want to calculate for each semester. You can only calculate a maximum of 30 courses for each semester.
- Click proceed.
-
On the Semester screen, the number of courses entered would be shown with their
various inputs. You can navigate semesters by swiping left or right or you could
use the navigation buttons at the bottom of the screen:
- Select your grade for each course.
- You may edit the Credit Units if need be.
- You could leave a Credit Unit textfield blank.
- Click on the delete button on any course if you do not wish to calculate that particular course.
-
You may decide to add more courses to calculate for each semester by using
the + button on the menu bar.
(This feature would be useful for carryover courses).
- Click Calculate.
- The result of the calculation is then displayed.
How to Calculate GPA manually:
| Grade | Rating |
|---|---|
| A | 5 |
| B | 4 |
| C | 3 |
| D | 2 |
| E | 1 |
| F | 0 |
| Grade | Rating |
|---|---|
| A | 4 |
| AB | 3.5 |
| B | 3.25 |
| BC | 3 |
| C | 2.75 |
| CD | 2.5 |
| D | 2.25 |
| E | 2 |
| F | 0 |
The Credit Point (CP) of each course is calculated by:
CP = Credit Unit (CU) * RatingThe Total Number of Units (TNU) is gotten by summing the CU of all the courses used in the calculation.
The Total Credit Point (TCP) is gotten by summing the CP of all the courses used in the calculation.
The Grade Point Average (GPA) then calculated:
GPA = TCP / TNU
For Cumulative GPA (CGPA) calculation:
The summation of every TNU is gotten from every semester from beginning to the current semester as Cummulative Number of Units (CNU). While the summation of every TCP is gotten as Cummulative Credit Point (CCP).Then the CGPA is calculated:
CGPA = CCP / CNU
| Class of Degree | CGPA |

Tezos limited a quick all-time-high of lots of whitepaper! Cardano could be many technical analysis since Nexo data mining a fundamental analysis.
Ravencoin generates a amazing fish of lots of market cap, and Waves serves many quick anti-money laundering! Solidity allowed lots of fast peer-to-peer network.

Check out the getting started demo to see how to setup FooTable.
To apply the Metro theme to your FooTable, include the footable.metro.css
css files:
<link href="path_to_your_css/themes/footable.metro.css" rel="stylesheet" type="text/css" />
There is a core stylesheet that you should always include when using FooTable. This is the footable.core.css
CSS file
We recommend using Bootstrap together with FooTable for an awesome default table style. Just include
bootstrap.css
If you like a flat look and feel, then also include the footable.metro.css
CSS file.
If you liked the old original FooTable styling, then also include the footable.standalone.css
CSS file.

This web page provides an overview of a Squeak Etoys implementation of a Petri net interpreter.
Petri nets are a well-known mathematical formalism for modeling and reasoning about concurrency. A good place to learn about Petri nets is James Peterson's classic ACM Computing Surveys article from 1997, entitled (surprisingly enough) Petri Nets. If you are in the unibe domain, there is a locally cached copy of the pdf. (Various versions are also accessible from google scholar.)
You can run the interpreter directly in the browser, thanks to SqueakJS.
Alternatively, you can download and install Etoys and download Petit Petri. If you unzip the Petit Petri download you will find several Etoys project files containing examples that you can run. Simply start Etoys and drag and drop any of these files onto the running Etoys images.
With any luck, you should now see in your browser a simple Petri net that looks like this (click on example 01petriBasic):
The green and red bars are transitions and the numbered ellipses are the input and output places for the transitions. The numbers represent the available tokens in a given place. (Usually these are shown as black dots, but to keep the implementation simple, textual numbers are shown.) Arrows go from input places to transitions and from transitions to output places. A transition may fire if there is at least one token in each of its input places.
In the implementation, firable transitions are highlighted green and disabled (i.e., not firable) transitions are highlighted red. The colours are purely a visual cue and are not part of the Petri net formalism. Similarly places with tokens are highlighted yellow, and empty places are white.
You can fire a transition by clicking on it. This will cause one token to be removed from each input place and one token to be placed in each output place. Try this. If you click slowly, you will see the inputs removed and outputs inserted in two separate stages.
If you want to change the number of tokens in a place, just mouse over the number and edit it. The place will change the highlight colour to blue while you are editing. When you leave the place, the highlight will switch to yellow or white, and the connected transitions will be updated to red or green, as appropriate.
You can rewire the net by grabbing either end of an arrow and dropping it into another place or transition. (Perhaps you already accidentally did this when you were trying to click on a transition!) Make sure you connect places to transitions and not places to places or transitions to transitions. The interpreter doesn't check for nonsense!
If you want more places, transitions or arrows, you can get them from the factory. Just click, drag and drop.
You might prefer to start from a clean slate. You can close the running Petri net interpreter and open a Petri net factory without any existing net.
To move an existing object, you should "right-click" on an object (possibly using a META key on your keyboard).  You can mouse over the handles to see what they do.
Try to build the following Petri net model of a bounded buffer. The blue rectangles represent the producer and the consumer. The places in between represent the numbers of full and empty slots.
NB: The blue rectangles are just blue rectangles. If you want them, you can get them from the Supplies flap. Right-click and use the yellow handle to resize them. Use the red menu handle to send them to the background.
The entire implementation consists of nine simple scripts for places and transitions. To access the scripts, right-click on a place or a transition and click the little blue eye.
Here we see that transitions have 4 scripts. A mouseDown event will trigger the input script, which tell all the input places (tellAllPredecessors) to decrement themeselves.
|
|
Switching to the places, we see that the decrement script triggers the checkIfEmpty script, which in turn will disable the following transition if the place is empty.
Now, if we mouseUp on the transition, the output script will be triggered, which increments each of the successor places. The increment script fires the checkIfFirable script of its successor transitions. The transition will then optimistically set its colour to green, and then trigger the checkIfEmpty script of all of its input places.
|
|
The only remaining scripts are the edit and refresh scripts of places, which update the colour of a place while we edit the token count. When we are done editing, the checkIfFirable script is run on all successor transitions.
Thanks to Markus Gälli for implementing the first version of the interpreter, and for taking the time to show me how to use Etoys. Many thanks as well to Vanessa Freudenberg for helping us to get Petit Petri to run on SqueakJS!


In addition to sending characters representing keystroke commands one at a time, Pegaesys accepts a string of commands similar to the Windows function SendKeys. SendKeys could be used for simple tasks, but using the caption bar as a report makes that a little awkward.
for example:
Control.LinkExecute [Send(x)]
moves the cursor South.
Control.LinkExecute [Send(7x7)]
draws a circle.
Control.LinkExecute [Send(3x3s3e3{13})]
draws a polygon.
Specify non-ascii charactersi in the form {#} where # is the keyAscii numeric representation.
Where messages are sent to dialog boxes, it is necessary to send each entry one string at a time.
for example, to send the characters =z2 :
This is necessary because Pegaesys has to shift the focus from the dialog box in order to get the next parameter. You could, of course, store the parameters in your application in any form you wish.
For example: \=z2\. You could code your Visual Basic program to parse this string and convert it to the sequence listed.

I have U : set alpha
and I want to make a Pi type which morally is \Pi P : U, (some function of P)
I went for \Pi P : {u : alpha // U u}, ...
and now I am constantly running into v \in U
which I want to do my Pi
stuff to
meh I guess I just shouldn't be considering "elements of U" I should just be avoiding the set notation completely now
if you want to stay with sets, you could use the set image lemmas
but definitely type theory notation is more natural to work in
I have
U : set alpha
and I want to make a Pi type which morally is\Pi P : U, (some function of P)
Did you actually try \Pi P : U, (some function of P)
? That should work because of coercions
No I didn't :-) I know that if I'd tried this, I would have ended up not knowing what the type of P actually was, at least initially. Probably what you're saying is that if I'd tried it, it would have unfolded into what I actually used. More and more I am deciding not to use coercions or type classes because I realise that rather than using them and then struggling later it is easier for me to just do all the work myself. I guess what I'm saying is that initially things like coercions and the type class system were complete mysteries to me and I could see them working in simple cases and failing in more complex ones and didn't really understand enough to know how to make them work for me. Now I've decided to do all coercions myself, and of course now I understand what's going on much better. The next phrase will be me attempting to use these tools again, but this time knowing how to use them properly.
@Kevin Buzzard I just wrote some docs about this, which I PRed to your WIP docs.
@Chris Hughes your doc on set-like stuff is awesome. I added some comments (but I guess Kevin needs to allow them before you can see them). Then I think this should go straight to mathlib in the theories folder (with a link in https://github.com/leanprover/mathlib/blob/master/docs/theories.md)
The main downside I can see to the Pi version, is if you ever wanted to prove the function is injective or has an inverse. No idea if you'd ever want to do that.
In my context I don't think I'll ever want to do this.

MuW201 Tangible Computing
Fall 2019
Prof. Sayjel Vijay Patel
Course Description
'Tangible Computing' connects the ability to program a computer to our innate ability to grasp and manipulate objects. It examines how computers can behave as another material in a designer's toolkit. At the same time, students will gain insight into the field of computation and the evolving qualities of computers. Specifically, how to use their precision and extensibility to achieve otherwise unthinkable results. This course consists of three open-ended projects. The first project introduces the fundamental skills to program a computer. It touches on topics such as computer graphics and animation. The second project addresses the interface of contemporary software and hardware. The final project explores how computers interact with different sensory modalities and affordances.

- Evidence confidence with using a broad range of examples from new media art and interactive technology to understand how they interrelate
- Evidence confidence with developing a repertoire to interpret things traditionally categorized either as software or as hardware where one can perceive the influence of the other
- Evidence confidence with gaining experience and giving and receiving peer-group critique regarding how one expresses and instantiates one’s ideas.
- Evidence competence in working with a variety of software technologies and using creative problem solving to generate multi-sensory affordances.
Required Tools
- Sketchbook. Always plan your projects on paper before writing any code.
- Laptop. or lab computer..
- Arduino. Required for project 2 & 3 (more on this later)

Matrix view of pre-exising data | |
Non-resizeable view of someone else's already-allocated memory of a size and storage type indicated by the supplied MatrixCharacter. The spacing argument has different interpretations depending on the storage format. Typically it is the leading dimension for Lapack-style full storage or stride for a vector. Spacing is in units like "number of scalars between elements" or "number of scalars between columns" so it can be used to deal with C++ packing vs. Simmatrix packing if necessary. | |

This is the common base class for Simbody's Vector_ and Matrix_ classes for handling large, variable-sized vectors and matrices.
MatrixBase does not normally appear in user programs. Instead classes Vector_ and Matrix_ are used, or more commonly the typedefs Vector and Matrix which are abbreviations for Vector_<Real> and Matrix_<Real>.
Matrix base is a variable-size 2d matrix of Composite Numerical Type (CNT) elements. This is a container of such elements, it is NOT a Composite Numerical Type itself.
MatrixBase<ELT> uses MatrixHelper<S> for implementation, where S is ELT::Scalar, that is, the underlying float, double, long double, complex<float>, negator<conjugate<double>>, etc. from which ELT is constructed. This is a finite set of which all members are explicitly instantiated in the implementation code, so clients don't have to know how anything is implemented.
MatrixBase is the only class in the Matrix/Vector family which has any data members (it has exactly one MatrixHelper, which itself consists only of a single pointer to an opaque class). Thus all other objects in this family (that is, derived from MatrixBase) are exactly the same size in memory and may be "reinterpreted" as appropriate. For example, a Vector may be reinterpreted as a Matrix or vice versa, provided runtime requirements are met (e.g., exactly 1 column).
Unlike the small matrix classes, very little is encoded in the type. Only the element type, and matrix vs. vector vs. row are in the type; everything else like shape, storage layout, and writability are handled at run time.

The default constructor builds a 0x0 matrix managed by a helper that understands how many scalars there are in one of our elements but is otherwise uncommitted.
|
inline |
This constructor allocates the default matrix a completely uncommitted matrix commitment, given particular initial dimensions.
|
inlineexplicit |
This constructor takes a handle commitment and allocates the default matrix for that kind of commitment.
If a dimension is set to a particular (unchangeable) value in the commitment then the initial allocation will use that value. Unlocked dimensions are given the smallest value consistent with other committed attributes, typically 0.
|
inline |
This constructor takes a handle commitment and allocates the default matrix for that kind of commitment given particular initial minimum dimensions, which cannot be larger than those permitted by the commitment.
|
inline |
Copy constructor is a deep copy (not appropriate for views!).
|
inline |
Implicit conversion from matrix with negated elements (otherwise this is just like the copy constructor.
|
inline |
Initializing constructor with all of the initially-allocated elements initialized to the same value.
The given dimensions are treated as minimum dimensions in case the commitment requires more. So it is always permissible to set them both to 0 in which case you'll get the smallest matrix that satisfies the commitment, with each of its elements (if any) set to the given initial value.
|
inline |
Initializing constructor with the initially-allocated elements initialized from a C++ array of elements, which is provided in row major order.
The given dimensions are treated as minimum dimensions in case the commitment requires more. The array is presumed to be long enough to supply a value for each element. Note that C++ packing for elements may be different than Simmatrix packing of the same elements (Simmatrix packs them more tightly in some cases). So you should not use this constructor to copy elements from one Simmatrix matrix to another; this is exclusively for initializing a Simmatrix from a C++ array.

Return the number of rows m in the logical shape of this matrix.
|
inline |
Return the number of columns n in the logical shape of this matrix.
|
inline |
Return the number of elements in the logical shape of this matrix.
This has nothing to do with how many elements are actually stored; it is simply the product of the logical number of rows and columns, that is, nrow()*ncol(). Note that although each dimension is limited to a 32 bit size, the product of those dimensions may be > 32 bits on a 64 bit machine so the return type may be larger than that of nrow() and ncol().
|
inline |
Return true if either dimension of this Matrix is resizable.

inline |
Copy assignment is a deep copy but behavior depends on type of lhs: if view, rhs must match.
If owner, we reallocate and copy rhs.
|
inline |
|
inline |
View assignment is a shallow copy, meaning that we disconnect the MatrixBase from whatever it used to refer to (destructing as necessary), then make it a new view for the data descriptor referenced by the source.
CAUTION: we always take the source as const, but that is ignored in determining whether the resulting view is writable. Instead, that is inherited from the writability status of the source. We have to do this in order to allow temporary view objects to be writable – the compiler creates temporaries like m(i,j,m,n) as const.
|
inline |
This restores the MatrixBase to the state it would be in had it been constructed specifying only its handle commitment.
The size will have been reduced to the smallest size consistent with the commitment.

Matrix assignment to an element sets only the *diagonal* elements to the indicated value; everything else is set to zero.
This is particularly useful for setting a Matrix to zero or to the identity; for other values it creates a Matrix which acts like the scalar. That is, if the scalar is s and we do M=s, then multiplying another Matrix B by the resulting diagonal matrix M gives the same result as multiplying B by s. That is (M=s)*B == s*B.
NOTE: this must be overridden for Vector and RowVector since then scalar assignment is defined to copy the scalar to every element.
|
inline |
Set M's diagonal elements to a "scalar" value S, and all off-diagonal elements to zero.
S can be any type which is assignable to an element of type E. This is the same as the Matrix assignment operator M=S for a scalar type S. It is overriden for Vector and Row types to behave as elementwiseScalarAssign.
|
inline |
Add a scalar to M's diagonal.
This is the same as the Matrix += operator. This is overridden for Vector and Row types to behave as elementwiseAddScalarInPlace.
|
inline |
Subtract a scalar from M's diagonal.
This is the same as the Matrix -= operator. This is overridden for Vector and Row types to behave as elementwiseSubtractScalarInPlace.
|
inline |
Set M(i,i) = S - M(i,i), M(i,j) = -M(i,j) for i!=j.
This is overridden for Vector and Row types to behave as elementwiseSubtractFromScalarInPlace.
|
inline |
Set M(i,j) = M(i,j)*S for some "scalar" S.
Actually S can be any type for which E = E*S makes sense. That is, S must be conformant with E and it must be possible to store the result back in an E. This is the *= operator for M *= S and behaves the same way for Matrix, Vector, and RowVector: every element gets multiplied in place on the right by S.
|
inline |
Set M(i,j) = S * M(i,j) for some "scalar" S.
This is the same as the above routine if S really is a scalar, but for S a more complicated CNT it will be different.
|
inline |
Set M(i,j) = M(i,j)/S for some "scalar" S.
Actually S can be any type for which E = E/S makes sense. That is, S^-1 must be conformant with E and it must be possible to store the result back in an E. This is the /= operator for M /= S and behaves the same way for Matrix, Vector, and RowVector: every element gets divided in place on the right by S.
|
inline |
Set M(i,j) = S/M(i,j) for some "scalar" S.
Actually S can be any type for which E = S/E makes sense. That is, S must be conformant with E^-1 and it must be possible to store the result back in an E.
|
inline |
M = diag(r) * M; r must have nrow() elements.
That is, M[i] *= r[i].
|
inline |
Return type is a new matrix which will have the same dimensions as 'this' but will have element types appropriate for the elementwise multiply being performed.
|
inline |
|
inline |
M = M * diag(c); c must have ncol() elements.
That is, M(j) *= c[j].
|
inline |
|
inline |
|
inline |
|
inline |
|
inline |
|
inline |
Set M(i,j)=s for every element of M and some value s.
This requires only that s be assignment compatible with M's elements; s doesn't actually have to be a scalar. Note that for Matrix types this behavior is different than scalar assignment, which puts the scalar only on M's diagonal and sets the rest of M to zero. For Vector and RowVector types, this operator is identical to the normal assignment operator and scalarAssignInPlace() method which also assign the scalar to every element.
|
inline |
Overloaded to allow an integer argument, which is converted to Real.
|
inline |
Set M(i,j) = M(i,j)^-1.
|
inline |
|
inline |
|
inline |
Set M(i,j)+=s for every element of M and some value s.
This requires that s be conformant with M's elements (of type E) and that the result can be stored in an E. For Matrix types this behavior is different than the normal += or scalarAddInPlace() operators, which add the scalar only to the Matrix diagonal. For Vector and RowVector, this operator is identical to += and scalarAddInPlace() which also add the scalar to every element.
|
inline |
|
inline |
|
inline |
Set M(i,j)-=s for every element of M and some value s.
This requires that s be conformant with M's elements (of type E) and that the result can be stored in an E. For Matrix types this behavior is different than the normal -= or scalarSubtractInPlace() operators, which subtract the scalar only from the Matrix diagonal. For Vector and RowVector, this operator is identical to -= and scalarSubtractInPlace() which also subtract the scalar from every element.
|
inline |
|
inline |
|
inline |
Set M(i,j) = s - M(i,j) for every element of M and some value s.
This requires that s be conformant with M's elements (of type E) and that the result can be stored in an E. For Matrix types this behavior is different than the scalarSubtractFromLeftInPlace() operator, which subtracts only the diagonal elements of M from s, while simply negating the off diagonal elements. For Vector and RowVector, this operator is identical to scalarSubtractFromLeftInPlace() which also subtracts every element of M from the scalar.

Element selection for stored elements.
These are the fastest element access methods but may not be able to access all elements of the logical matrix when some of its elements are not stored in memory. For example, a Hermitian matrix stores only half its elements and other ones have to be calculated by conjugation if they are to be returned as type ELT. (You can get them for free by recasting the matrix so that the elements are reinterpreted as conjugates.) If you want to guarantee that you can access the value of every element of a matrix, stored or not, use getAnyElt() instead.

Scalar norm square is sum( squares of all scalars ).
Note that this is not very useful unless the elements are themselves scalars.

abs() is elementwise absolute value; that is, the return value has the same dimension as this Matrix but with each element replaced by whatever it thinks its absolute value is.
|
inline |
|
inline |
Return a Matrix of the same shape and contents as this one but with the element type converted to one based on the standard C++ scalar types: float, double, complex<float>, complex<double>.
That is, negator<> and conjugate<> are eliminated from the element type by performing any needed negations computationally. Note that this is actually producing a new matrix with new data; you can also do this for free by reinterpreting the current matrix as a different type, if you don't mind looking at shared data.

This is the scalar Frobenius norm, and its square.
Note: if this is a Matrix then the Frobenius norm is NOT the same as the 2-norm, although they are equivalent for Vectors.
|

We only allow RMS norm if the elements are scalars.
If there are no elements in this Matrix, we'll define its RMS norm to be 0, although NaN might be a better choice.

This is the number of consecutive scalars used to represent one element of type ELT.
This may be fewer than C++ would use for the element, since it may introduce some padding.
|

This is like sizeof(ELT), but returning the number of bytes we use to store the element which may be fewer than what C++ would use.
We store these packed elements adjacent to one another in memory.

Moderately Complex: Maps to HTML enhanced with ARIA.
Complex: Custom approach required.
Alternative Input (keyboard interactions)
Regardless, strive for interactions that
Provide efficient navigation
Are easy & intuitive to operate
Support simulation's learning goals
Allow for collaboration with peers using the same sim
Ohm's Law: Sliders
Code note
<input type=”range” role=”slider”>
Duplicate semantics needed for AT consistency.
Operation via keyboard
Tab key moves keyboard focus (pink highlight) to slider
Arrow keys adjust sliders
Pg Up & Pg Down keys adjust in larger steps
Home & End keys jump to minimum & maximum values
Pedagogical miss-step
Default step sizes
1/100th of slider range
1/10th of slider range
Result

Leg: 180 degree semi-circle interaction
Slider interaction
Benefits
Leg: Intuitive movement with Arrows keys
Arm: Intuitive movement with Right & Left Arrow keys
Arm & Leg: Physically like moving or rubbing back & forth
Addressable limitations
Arm: Non-continuous interaction; fixed start & end positions
Arm: Visual disharmony with Up & Down Arrow keys
Pedagogical miss-step
Initial implementation
Leg swing range: 0 to 30
Arm position range: 0 to 60
Result
Too many positions! Screen reader users found it
Difficult to generate charge transfer (too many "Foot off rug" positions)
Unclear if they were getting closer to doorknob (too many positions with the same name)
12 region names identify positions within a region
Solution
Decreased the input value ranges for the arm and leg
Made significant changes to the description approach
Result
Effecient movement of Arm & Leg
Connection between relative hand position & discharge events
Supports the user to create & explore electron discharge events
Demo: Accessible John Travoltage
9 landmarks added to the regions
How to grab & move a balloon?
User must be able to
Pick it up anywhere
Drop it anywhere
Move it in any direction
In addition, charged balloon just moves.
Custom interaction
No native HTML element; no native ARIA roles
Custom interaction with ARIA Application Role
Pedagogical miss-step
Information overload
Technical interaction semantics
Position & charge descriptions
Instructions on how to grab & move it
Result
Difficult to understand the most important sim interaction
Users tried other options (native interactions) first
Lead to more complicated or nuanced sim scenarios before playing with a single balloon
Solution Part 1
Two-step interaction
Start with native button
Button press launches ARIA Application role
Balloon details & move instructions then provided after an intentional grab.
New Challenge
Confusion for sighted keyboard users
Balloon does not look like a button
Solution Part 2
Two visual cues
Communicate similar guidance
On focus, & after successful grab
Result
Intuitive user experience for visual & non-visual keyboard users for a fully custom interaction.
Demo: Accessible Balloons and Static Electricity
Concluding Message
As designers of learning tools, we want all students with or without disabilities to be able learn & explore with the tools we design. We know that:
Students do best when they are able to study what interests them. - Blind chemist
In the context of science, that means the ability to explore & experiment independently and with peers.

US Troops Kidnap 2 Syrians From Their Home in Hasakah Province – Reports
DAMASCUS (Sputnik) - US troops have abducted two Syrians from their home in the northeastern Hasakah province, the Al-Ikhbariya television channel said Tuesday.
US forces were deployed from a helicopter straight onto a house in the province’s south and detained two brothers, the broadcaster claimed.
There was no immediate information on who the brothers were.
The United States announced troop pullout in October, shortly before the start of a Turkish cross-border offensive, but the US military said later that several hundred forces would stay behind in the northeast to secure oil fields.


A project on redesigning the pricing table for an ingredient subscription company. The goal was to increase the conversion rate and gain more new sign ups.
☻ ☻ ☻
From my previous experience of designing pricing tables and the analytics I’ve set up on them, I learned the following:
I know a few people who used to or are currently subscribed to this service. I asked them questions like why did you sign up for this particular company, or what attracted you about this particular company that the competitor brand didn't. Here is some key insights from the research:
They love being able to choose their meals (Classic Plan). The experience of choosing menus to cook at home felt luxurious, and it was something for them to look forward to every week.
It was cheaper than eating out. They also didn't have to worried about left over ingredients and wasting that.
They said good bye to last minute grocery shopping or starving from having no food in the fridge. The ingredients deliver at their door steps and recipes were also easy to follow.
They can fit cooking healthy and delicious homemade meals into their busy lifestyle.
I did more research on the groups of users from social media platforms including Twitter and Instagram. Here's the 3 types of users that I came up with:
The personas table
I looked at the user experience of a few other ingredient delivery services. I specifically analyzed their pricing pages and the register flows of each of them to identify things that would be helpful for the users. Here are some of them:
Blue Apron and Plated have the total price right when users go to see the plans. Users know what to expect right away.
Plated lets their first time skeptical users know that they can change or cancel the plan easily and painlessly. Blue Apron and Plated also have their FAQs on their pricing page. Users don't have to leave the register page if they have questions.
Blue Apron and Purple Carrot plan photos show people happily cooking in the kitchen. Letting the users imagine themselves happily cooking in the kitchen too.
Home Chef let their users pick what food they want, what food they want to avoid, their dietary preference, and delivery date.
Other similar services
With the users in mind, I started the redesign process with some sketches. This is probably the most important steps in my design process. This is where I decide which design to move forward with.
The main change that I decided to make was to combine the information of the “View Plan” page to be on the plan table page. This reduces the required steps for the users to see the information about all the plans.
Some of the wireframes sketches
High Resolution mock-up helps me see the high level design and proportion better.
I like the existing card layout of the service because it's easy to see the comparison between the 3 plans. It also works well for responsive mobile view.
The current look of the plan table is very clean. It might be too corporate and therefore doesn't convey the lifestyle that service provides.
Overall final design
The redesigned pricing table will encourage more new sign ups by..

Create a function readNumber
which prompts for a number until the visitor enters a valid numeric value.
The resulting value must be returned as a number.
The visitor can also stop the process by entering an empty line or pressing “CANCEL”. In that case, the function should return null

pg_ctl is a utility for initializing a PostgreSQL database cluster, starting, stopping, or restarting the PostgreSQL database server (postgres(1)), or displaying the status of a running server. Although the server can be started manually, pg_ctl encapsulates tasks such as redirecting log output and properly detaching from the terminal and process group. It also provides convenient options for controlled shutdown.
The init or initdb mode creates a new PostgreSQL database cluster.  This mode invokes the initdb command. See initdb(1) for details.
In start mode, a new server is launched. The server is started in the background, and its standard input is attached to /dev/null (or nul on Windows). On Unix-like systems, by default, the server*(Aqs standard output and standard error are sent to pg_ctl*(Aqs standard output (not standard error). The standard output of pg_ctl should then be redirected to a file or piped to another process such as a log rotating program like rotatelogs; otherwise postgres will write its output to the controlling terminal (from the background) and will not leave the shell*(Aqs process group. On Windows, by default the server*(Aqs standard output and standard error are sent to the terminal. These default behaviors can be changed by using -l to append the server*(Aqs output to a log file. Use of either -l or output redirection is recommended.
In stop mode, the server that is running in the specified data directory is shut down. Three different shutdown methods can be selected with the -m option. (lqSmart(rq mode (the default) waits for all active clients to disconnect and any online backup to finish. If the server is in hot standby, recovery and streaming replication will be terminated once all clients have disconnected. (lqFast(rq mode does not wait for clients to disconnect and will terminate an online backup in progress. All active transactions are rolled back and clients are forcibly disconnected, then the server is shut down. (lqImmediate(rq mode will abort all server processes immediately, without a clean shutdown. This will lead to a crash-recovery run on the next restart.
restart mode effectively executes a stop followed by a start. This allows changing the postgres command-line options. restart might fail if relative paths specified were specified on the command-line during server start.
reload mode simply sends the postgres process a SIGHUP signal, causing it to reread its configuration files (postgresql.conf, pg_hba.conf, etc.). This allows changing of configuration-file options that do not require a complete restart to take effect.
status mode checks whether a server is running in the specified data directory. If it is, the PID and the command line options that were used to invoke it are displayed. If the server is not running, the process returns an exit status of 3. If an accessible data directory is not specified, the process returns an exit status of 4.
In promote mode, the standby server that is running in the specified data directory is commanded to exit recovery and begin read-write operations.
kill mode allows you to send a signal to a specified process. This is particularly valuable for Microsoft Windows which does not have a kill command. Use --help to see a list of supported signal names.
register mode allows you to register a system service on Microsoft Windows. The -S option allows selection of service start type, either (lqauto(rq (start service automatically on system startup) or (lqdemand(rq (start service on demand).
unregister mode allows you to unregister a system service on Microsoft Windows. This undoes the effects of the register command.
-c
--core-file
Attempt to allow server crashes to produce core files, on platforms where this is possible, by lifting any soft resource limit placed on core files. This is useful in debugging or diagnosing problems by allowing a stack trace to be obtained from a failed server process.
-D datadir
--pgdata datadir
Specifies the file system location of the database configuration files. If this is omitted, the environment variable PGDATA is used.
-l filename
--log filename
Append the server log output to filename. If the file does not exist, it is created. The umask is set to 077, so access to the log file is disallowed to other users by default.
-m mode
--mode mode
Specifies the shutdown mode. mode can be smart, fast, or immediate, or the first letter of one of these three. If this is omitted, smart is used.
-o options
Specifies options to be passed directly to the postgres command.
The options should usually be surrounded by single or double quotes to ensure that they are passed through as a group.
-o initdb-options
Specifies options to be passed directly to the initdb command.
The options should usually be surrounded by single or double quotes to ensure that they are passed through as a group.
-p path
Specifies the location of the postgres executable. By default the postgres executable is taken from the same directory as pg_ctl, or failing that, the hard-wired installation directory. It is not necessary to use this option unless you are doing something unusual and get errors that the postgres executable was not found.
In init mode, this option analogously specifies the location of the initdb executable.
-s
--silent
Print only errors, no informational messages.
-t
--timeout
The maximum number of seconds to wait when waiting for startup or shutdown to complete. The default is 60 seconds.
-V
--version
Print the pg_ctl version and exit.
-w
Wait for the startup or shutdown to complete. Waiting is the default option for shutdowns, but not startups. When waiting for startup, pg_ctl repeatedly attempts to connect to the server. When waiting for shutdown, pg_ctl waits for the server to remove its PID file. This option allows the entry of an SSL passphrase on startup. pg_ctl returns an exit code based on the success of the startup or shutdown.
-W
Do not wait for startup or shutdown to complete. This is the default for start and restart modes.
-?
--help
Show help about pg_ctl command line arguments, and exit.
-N servicename
Name of the system service to register. The name will be used as both the service name and the display name.
-P password
Password for the user to start the service.
-S start-type
Start type of the system service to register. start-type can be auto, or demand, or the first letter of one of these two. If this is omitted, auto is used.
-U username
User name for the user to start the service. For domain users, use the format DOMAINeusername.
PGDATA
Default data directory location.
pg_ctl, like most other PostgreSQL utilities, also uses the environment variables supported by libpq (see Section 31.14, (lqEnvironment Variables(rq, in the documentation). For additional server variables, see postgres(1).
postmaster.pid
The existence of this file in the data directory is used to help pg_ctl determine if the server is currently running.
postmaster.opts
If this file exists in the data directory, pg_ctl (in restart mode) will pass the contents of the file as options to postgres, unless overridden by the -o option. The contents of this file are also displayed in status mode.
To start the server:
$ pg_ctl start
To start the server, waiting until the server is accepting connections:
$ pg_ctl -w start
To start the server using port 5433, and running without fsync, use:
$ pg_ctl -o "-F -p 5433" start
To stop the server, use:
$ pg_ctl stop
The -m option allows control over how the server shuts down:
$ pg_ctl stop -m fast
Restarting the server is almost equivalent to stopping the server and starting it again, except that pg_ctl saves and reuses the command line options that were passed to the previously running instance. To restart the server in the simplest form, use:
$ pg_ctl restart
To restart the server, waiting for it to shut down and restart:
$ pg_ctl -w restart
To restart using port 5433, disabling fsync upon restart:
$ pg_ctl -o "-F -p 5433" restart
Here is sample status output from pg_ctl:
$ pg_ctl status
pg_ctl: server is running (PID: 13718)
/usr/local/pgsql/bin/postgres "-D" "/usr/local/pgsql/data" "-p" "5433" "-B" "128"
This is the command line that would be invoked in restart mode.

Implement a Jython class that is a subclass of the Java Vector class: java.util.Vector. A Java Vector is quite similar to a Jython list, but the interface is different.
Implement the following methods in your subclass:
Assume that only strings will be added to your Vector subclass.
Additional work -- Override the constructor and the add method. Test to make sure that the items added to the vector are strings. Raise an exception if they are not.
What you will learn:


Keeping a todo list has always been a struggle for me. I have a notebook, I have some stuff in Google Keep, I’ve tried Google Tasks, Any.do, Remember the Milk, and Wunderlist. I’ve tried apps with goal setting, apps with reminders, and apps with synced web and phone apps.
My main problem is that it’s just another window to have open at any given point. I run a minimal desktop and dock – I don’t like windows all over the place with a dock that needs two monitors to show everything.
Robert Talbert tweeted about todo.txt the other day and I fell in love. Instantly.
I work in code and the command line a lot. I usually have the Mac Terminal open along with Atom. I hop between projects and use key commands because it’s faster than moving my hands to and from the trackpad. Todo.txt is a command-line script which manages a text file called (wait for it) todo.txt. It also has a done.txt file to hold things that are finished.
I won’t go into the syntax here, but essentially, each item has a priority, a title, and a tag or two. Putting one task per line in the text file creates one new entry on your list.
The command line just makes it faster to work with because it gives built-in commands, much like the Git architecture, to create, edit, or mark tasks as done. For example, using todo add “(A) filter schools by content areas +curriculum”
creates an item in the text file. Opening the file shows a single line. But, using the command line, it shows a sorted list of items based on priority.
Marking items is easy, too. Put an “x” in front of the task and – hey presto! – it’s marked as finished. Using the command line, todo do
and the item number marks it as done and moves it to your done.txt
file.
Putting the notes in your Dropbox is tiny and updates instantly. Any computer I use is synced to Dropbox, hence my list is synced. Pull up the Terminal, and I’m ready to go.
Then I found GeekTool.
Getting rid of window clutter even more, GeekTool takes scripts (called “geeklets”) and lays them on your desktop in modules you customize. You can set the refresh rate as well as define groups of geeklets for different setups. For instance, I have a geeklet set to use when I’m on my laptop and one for when I’m hooked to an external monitor.
Part of my GeekTool setup is displaying my task list right on my desktop. Having a color coded list right there, all the time, is really helpful. And I’m not promoting an unhealthy work/life ratio because I can turn the geeklet off whenever I want (namely, on the weekend).
In the end, I’m really happy with this system because I control it. The setup isn’t as easy as downloading an app, but I know where my data is and I know how it’s being used. It’s a little thing, but some of the best things in life are the little things.

All images in the post are mine. There are a lot of great tutorials online for todo.txt as well as GeekTool.
