Frameshop is a practical WYSIWYG tool for game developers to create texture atlases and frame animations. Considering texture and animation packaging is all along important for game development on each platform, an efficient tool is always profoundly required, Frameshop can meet these requirements well. It runs on Windows only for the moment.
• Texture atlas packaging;
• Multi atlas page support;
• Atlas frame rotation support;
• Atlas frame padding support;
• Format conversion plugin system;
• Frame animation editing;
• Animation helper rectangle data editing.
The main window appears as below after you started Frameshop; it is composited by five areas.
Toolbar sits at the top, most of the project/texture file operations are done here.
There is a big "Page" view in the middle of the main window, we can create/remove texture atlas pages and add/remove frames under a page here.
The checkered picture box shows the content of a page. A page is represented as a folder in a tree view at the left top of the page view; all frames associated in a page are listed under a page folder representation. Page command strip is at the bottom.
Inspector view is as known as property panel in some other software, all editable properties of a page can be modified with it.
Texture assets frames are listed here in preview mode, you can add new ones to the list or remove from it, or pick textures to add to an atlas page.
Runtime status information is shown in the box.
Click the "New" button on the toolbar to create a Frameshop project package, a configuration window will show as below.
Choose an appropriate resolution for a texture atlas page, after that new created pages will use that specified size as default; the size of each page can be changed independently later.
Vector texture scale is a factor that will be applied to a .SVG (Scalable Vector Graphics) file at the importing moment.
Click the "Add Texture" button on the toolbar to add texture files into working project as assets, or click the "Add Folder" button to add textures inside a folder (recursively as default). Imported textures will be listed in the frame list. You can also drag and drop a texture file or folder to the frame list to do so.
Frameshop supports five types of texture file as below.
• PNG
• BMP
• JPG
• SVG
• TGA
To add frame assets into an atlas page, select a target page in the page/frame list to add to, then simply drag them from the frame list and drop to the center page view area; frames can be multi selected while Ctrl key is pressed down. The page/frame list and the page atlas view will be updated immediately when a frame is added. You can double click on a frame assets to perform adding as well.
Frameshop neither copies original textures to the project folder nor parse them into project file, it reads original raw texture files each time you open a project. Frameshop saves a relative path if a texture file is under the same disk with a project file; otherwise it saves an absolute path.
Click the "Save" button to save a Frameshop project package to disk.
Click the "Save As" button to save current Frameshop project to another path and use that path as the working one.
Click the "Open" button to show an open file dialog, and then choose a Frameshop project file to load it. A project file is typed as .FSP; Frameshop can relate to it so that Frameshop could be launched automatically when you tried to open a project file directly. You can also drag and drop a project file to the toolbar to do so.
Click the "+" button below the page/frame list in the page view panel to add a new page.
Click the "-" button below the page atlas view to remove current page.
Double click a frame in the page atlas view to remove it. Or right click on a frame item (either in the page/frame list or in the page atlas view) and choose "Remove from Page" to do so.
Pick a single item from the combo box on top of the frame list to show it only in the frame list view. Or type some letters and hit enter to match and filter frames approximately.
In the inspector view we can edit properties of a selected page.
A page name is unique in a Frameshop project scope; and it CANNOT contains any of these charactors: , . ! ? * : | < > " / \.
If the "AllowRotation" property is set true, Frameshop might try to rotate a frame when packing it into an atlas to optimize space occupation.
The "Padding" value will be applied to each frame in a page to make them get a few pixels away from other ones.
The "TextureSize" specifies a size of current page.
Modifications of "AllowRotation", "Padding" and "TextureSize" may cause atlas relayouting, the page may not be able to hold all packed frames after that relayouting, if so an ensurance dialog box will appear to ask you if you'd like to revert the change or keep it with some frame abandon in current atlas page.
Click the "Publish" button to export current Frameshop project, and make essential conversions at the same folder where the project file stays.
Frameshop supports customized command line tool invoking when publishing a project, so that we can make some format conversions with this functionality.
See 3.21.1 to get detail information about how to customize a conversion plugin.
Click the "Animation" button to open the animation editing window which appears as below.
The left side is a page/frame list which shows same contents as the one in the main window. The middle view is frame preview area. The right side is composited by a sequence list on top and a frame (in sequence) property grid.
Choose "File" -> "New" to create a new animation sequence.
Double click a frame item in the page/frame list to add it to the sequence. Or right click on an item and choose "Add to Sequence" to do so as well.
Click on a frame in the sequence to select it.
Choose "Edit" -> "Move Mode" to active move mode; then drag the frame in the preview area. Or in another way edit the "Offset" property in the property grid to do a fine adjustment.
Click on a frame in the sequence to select it.
Edit the "Time" property in the property grid.
Choose "Play" -> "Preview" to open the preview window as below.
You must be familiar with this easy to use player style window. Click the triangle button to play, double parallel line button to pause, square button to stop, clip button to switch loop on/off; use the slider bar on the timeline to pick frames.
Each frame in a sequence can contains three helper rectangles, these rectangles are independent data, you can use them for specific usage such as collision detection or object binding in your engine.
To edit a helper rectangle, follow the steps below.
Click on a frame in the sequence to select it.
Choose "Edit" -> "Quad Mode N" to active quad mode; then drag out a rectangle. Or in another way edit the "RectN" property in the property grid to do a fine adjustment. Notice 1, 2 and 3 substitute for "N" here.
Click the "Option" button on the main window to open the option configuration window. There are two tabs as below.
Format conversion plugin is a text based file that similar to a system shell processing batch; it doesn't do anything itself, but invokes other command line tools and pass arguments to them.
Frameshop can use four kinds of plugins that respectively process project folder, each texture, each page data, each animation. Plugins are all located in the "plugin" folder under the same folder where the Frameshop main EXE sits, a plugin is a .FSC file that you can view and edit using any text editor.
All plugins are listed in each combo box associated to operation types. You can simply choose an exist one to use it to process assuming targets; type an desired new plugin name in the combo box and press the "Edit" button to create a new plugin file.
The plugin syntax is as simple as a single line parameterized command with escape lexical tokens. Use the escape tokens below to represent published files/folders.
• $FULL$: full path
• $PARENT$: parent folder
• $FILE$: file name only
• $EXT$: file extension only
Open the options configuration window, switch to the "Misc" tab.
Check/uncheck "Relate Frameshop project (*.fsp) files" to relate/unrelate project files to Frameshop. You can double click a .FSP file to open it after it's related.
Open the options configuration window, switch to the "Misc" tab.
Check "Ensure before removing a frame" to show an insurance dialog after you were tending to remove a frame from the assets list.
Open the options configuration window, switch to the "Misc" tab.
Check "Add texture folders recursively" to parse all sub folders when parsing an outer one.


The version control system Git (cf. the excellent documentation under http://git-scm.com/) has become really popular recently. One reason for this is the success of Github (cf. http:github.com) as a (open source) code hosting platform based on Git. There are now also similar, alternative platforms available, like Codebreak (http://codebreak.com).
While, for example, Codebreak let’s you store as many private Git repositories as you like, with Github you have to pay for this feature. However, in principle, every server can serve as a Git server (even if not with the many nice, graphical features the aforementioned platforms provide).
To use the RPi as a Git server (or a “remote Git repository storage system”) does not require software-wise anything more the Git installed on the RPi. It should be installed already, if not do:
sudo apt-get install git
In addition, the RPi must be configured for SSH access (cf. SSH Access).
In what follows, we use a USB storage device to store the remote Git repositories. This allows to move your valuable backups/versions of your Git repositories and to access them from other devices as well.
Put a formatted USB stick into your RPi. The look up the mounting information:
sudo blkid
In my case, it is mounted as /dev/sda1. We want to permanently link the USB storage device to a directory in our home folder:
mkdir /home/pi/usb
Edit the following file:
sudo nano /etc/fstab
and add the line:
/dev/sda1 /home/pi/usb ext4 uid=pi, gid=pi, umask=0022, sync, auto, nosuid, rw, nouser 0 0
where some parameters might need to be changed due to your configuration (e.g. the directory or vfat instead of ext4 for the file system).
After a reboot, you should now be able to permanently access the (“any”) USB drive plugged into your RPi via /home/pi/usb.
Now that we have a proper storage device configured, we can add a remote repository to an existing one (I assume you are working with Git already and have a few repositories to use now; if not see below).
In my case, I take the repository of this tutorial which you can also find under http://github.com/yhilpisch/rpi as an example. Now do on the RPi the following:
cd /home/pi/usb
mkdir rpi.git
cd rpi.git
git init --bare
Then navigate on your local machine to the Git repository you want to push to the remote RPi location and do (cf. also Fixed IP Address for the domain name):
git remote add rpi pi@rpi.mydomain.net:/home/pi/usb/rpi.git
Then, you should be able to do something like:
git push rpi master
You can then, for instance, clone the repository to some other location via:
git clone pi@rpi.mydomain.net:/home/pi/usb/rpi.git
Of course, you can also generate a new user, say git, whose credentials you can easily and safely share with members of your team or with friends. You only have to make sure that this new user has read (or even maybe write) rights to the respective Git repository/folder (e.g. sudo chmod -R 755 /home/pi/usb/rpi).
If you do not have an example Git repository (but Git installed locally), you can do the following steps locally (assuming the the remote location was set up as above):
mkdir rpi
cd rpi
git init
# copy now some files into the the new directory
git add --all .
git commit -am 'Initial commit message.'
git remote add rpi pi@rpi.mydomain.net:/home/pi/usb/rpi.git
git push rpi master


Happy Birthday, my jaan
You know how you give me words right to rap about? Here is my word:
Birthday
My love, it's your birthday,
May you receive love and life in every way,
May you achieve greater heights and slay,
May the sun's rays kiss your face when you wake,
May your smile never fade, nor your style or your grace,
Nor your guile, nor your grades, nor the brightness of your flame,
May you have the best of days, babe,
Never change, and turn your pain into champagne!
You are my sunshine, my only sunshine.
"It start like the same story here: boy meets girl, and high school sweethearts with the instant chemistry and sparks flying left and right. Because this is a story it won't be so long as to include everything that happens. Instead, it's more about how they get closer, with the Cambodia trips, the sitting next to each other in class, the secret meetups and the rants on the call. They get tighter and tighter, more stronger than ever. They're best friends, they're lovers, they're a passionate couple. The work through their differences, they make time for each other, and they try new stuff together, from the softie at cheers while filming a documentary to watching game of thrones while sneakily having sex. In the middle of all this, they have cute moments, like how she came to visit his performance, despite her mother being angry at her, or how he scolded her when he feared that she was in danger.
At this point, they're beyond the point of best friendship, and story shifts to London, where both of them study. They explore, go on adventures, immerse themselves in the novelty of the place, all while discovering entirely new parts within each other. Then, at one lightbulb moment, when he runs back home from a party to find her sleeping in bed, looking precious and beautiful. She wakes up drowsily and he proposes to her. And after that, things get even more beautiful, with more electric nights, and explosive days, with glorious conversations and heart-catching gestures.
Climax of the story, where both of them admit their love to another, despite the arguments and fights that they argue over for no reason. At the end of each part, they keep on realizing the pointlessness of the bickering, because they know within that they love each other. That nothing will ever change. That they're at a place where anger and annoyance can't touch them. They're immortals in the books of love :)"
Dear Rutvi, I don’t know if you liked whatever I did for you over the last month or so, I don’t know whether you’ll remember it after some months or if you’ll cherish it after some years. All I know is, that I’ve had a wonderful time doing all of this, and more importantly, doing it for you. The only thing that I had in my mind while doing this was seeing your smile and seeing your eyes turn Chinese and your cheeks turning pinchable and your teeth turning into a Colgate advertisement.
Dear Rutvi, here’s wishing you a very happy birthday! I want you to know that you’re pretty much my most favorite of all time in the history of ever. You got this incredible way of making me happy and I wonder if I will ever be able to repay all this to you.
Dear Rutvi, I am ecstatic, and so very grateful that I have you as my best friend, my girlfriend, my soulmate, my trainer, my critic, my nurse, my partner-in-crime (the list goes on for quite some time). I couldn’t have asked for more from life. You are my home. I need to tell you that if ever I push you away, I don’t really mean it. We are going to talk it out. We will work out. Always. I love our chemistry. I love our equation. How amazing it is to find someone who wants to hear about all the things that go on in their lives. You and I, are a risk worth taking. We have a future that is brighter than the Sun and the stars. I can't wait to face it with you, together. We are lovebirds and we're soaring, flying, there's not a star in heaven that we can't reach :)
Dear Rutvi, sometimes we lie down side by side and I wrap my arm around your waist, or when we cuddle, and I can feel the warmth of your skin, I can’t help but think how lucky I am. You chose me of all people. You’re wonderful. And way out of my league. It's like winning the lottery that you chose me. I thank the heavens. Shout out to the lords and the gods, that you picked me. Every moment with you is bliss. The way we cook together, the way we dance together, the way we make love together. It's phenomenal.
Dear Rutvi, I hope you realize your importance not only to me, but to everyone who has been lucky enough to know you. I hope you know that whenever you feel down, I will be there and I will strive for your smile. I hope you remember I am going to be there for you no matter what.  You have helped your family become stronger than ever, you have helped those who take care of you with their lives make informed choices (like your wonderful Hetal didi!), you have even helped those who you don't know live better lives! You have taught them, showed them their true potential, and helped their find their wings!
Dear Rutvi, I fully intend on staying in your life for quite some time. I appreciate and adore you without restraints, and this friendship and the bond will never change. If anything, it will get stronger, and more unique. We are a duo to be reckoned with!
Dear Rutvi, be the amazing person that you are. Always and forever.

Attempting to solve the age-old rivalry by analyzing Reddit comments using Natural Language Processing
Using Reddit and Pushshift.io APIs, I collected comments from two different subreddits (r/cats and r/dogs). Preliminary EDA showed that of the 30 most frequent words in each subreddit, approximately 1/3 were unique to the class and 2/3 were the same in both.
CountVectorizer and TfidfVectorizer (NLP modules from scikit-learn) were each tested for vectorizing the text data. After preprocessing and vectorizing the text data, I trained various classification models to identify which subreddit a given post came from. Logistic regression, Random forest, and Multinomial naive Bayes models were trained and tested with Gridsearch. The final model used CountVectorizer and LogisticRegression to achieve 84.8% accuracy (compared to the baseline accuracy of 50% for balanced classes).
Sentiment analysis found that the comments in /r/cats were generally more positive than comments in /r/dogs, however I cannot conclude whether cats or dogs are superior. More research (and cute pet photos) are needed.
Skills and Tools Used:
Webscraping and APIs for data gathering
Natural Language Processing: Scikit-learn modules CountVectorizer, TfidfVectorizer
Helping hurricane preparedness using drone images and a convolutional neural network
I worked with a team of classmates on a real-world project for the World Bank. Our project goal was to use aerial drone image data to identify buildings in need of repairs, to prepare for future hurricanes. Given that there are approximately 80,000 buildings on the island of St. Lucia, developing a model that can quickly screen for damaged roofs would be useful for anyone assessing how to prepare the island for hurricane season.
We were provided with a large aerial image, taken by drone, of the town of Dennery, St. Lucia. Individual roof images were cropped by layering with a GIS shapefile of building locations. We then trained a CNN (convolutional neural network) to correctly classify images as either non-roof, good-quality roof, or poor-quality roof. Our model correctly identified 38% of the non-roof images and 73% of the poor roof images in the dataset, with a total accuracy for all three categories of 72% from a 56% baseline. This is a strong proof of concept for the model's viability if it could be trained on a larger set of images.
Skills and Tools Used:
Geospatial data: ArcGIS, Rasterio, Geopandas
Neural network modeling: Keras (Python deep learning library)
Business problem: What strategies can an Airbnb host take to increase profit? Using data scraped from Airbnb from 2015 - 2018 by Inside Airbnb, I built a model to predict prices for Airbnb listings in Washington DC based on features such as size, location, and time of year, and identified the most influential features. Linear regression was chosen for the interpretability of the model, so that the relative impact of various features on the price could be interpreted from the model. The model was optimized using various data preprocessing and modeling techniques: features were engineered and scaled, log transformation was applied to the target variable (price), and Lasso regression was used for both variable selection and regularization.
Findings: The final model performed better than the baseline (where the baseline predicts the mean price), with R2 of 0.6557 vs R2 of 0 for baseline. Size-related features such as number of guests accommodated, number of bedrooms and bathrooms had the greatest correlation with higher prices. For location features, neighborhoods closer to downtown DC had higher positive coefficients than other neighborhoods.
Time series and missing data imputation: One possible future improvement would be to apply time series modeling to better predict fluctuations in price over time. However, a daily price for each Airbnb listing was available for only the dates when data was scraped: 11/15/18, 10/12/18, 9/14/18, 8/18/18, 7/20/18, 5/18/18, 4/15/18, 5/10/17, 3/10/17, 10/3/15. The scraped data from the reservation calendars for the listings only included prices for the dates when the listing is available, approximately 40% of the total dates, making data imputation difficult. To get better daily price and reservation data, daily scrapes could be set up to run automatically.
Skills and Tools Used:
Data Preprocessing and Feature Engineering: Log transformation; Scikit-learn modules: StandardScaler, PolynomialFeatures
Linear Regression and Regularization: Scikit-learn modules: LinearRegression, RidgeCV, LassoCV

The built-in URL class provides a convenient interface for creating and parsing URLs.
There are no networking methods that require exactly a URL
object, strings are good enough. So technically we don’t have to use URL
. But sometimes it can be really helpful.
The syntax to create a new URL
object:
url
– the full URL or only path (if base is set, see below),base
– an optional base URL: if set and url
argument has only path, then the URL is generated relative to base
.For example:
These two URLs are same:
```js run let url1 = new URL(“https://javascript.info/profile/admin”); let url2 = new URL(“/profile/admin”, “https://javascript.info”);
alert(url1); // https://javascript.info/profile/admin alert(url2); // https://javascript.info/profile/admin ```
We can easily create a new URL based on the path relative to an existing URL:
```js run let url = new URL(“https://javascript.info/profile/admin”); let newUrl = new URL(“tester”, url);
alert(newUrl); // https://javascript.info/profile/tester ```
The URL
object immediately allows us to access its components, so it’s a nice way to parse the url, e.g.:
```js run let url = new URL(“https://javascript.info/url”);
alert(url.protocol); // https: alert(url.host); // javascript.info alert(url.pathname); // /url ```
Here’s the cheatsheet for URL components:
href
is the full url, same as url.toString()
protocol
ends with the colon character :
search
- a string of parameters, starts with the question mark ?
hash
starts with the hash character #
user
and password
properties if HTTP authentication is present<EMAIL_ADDRESS>(not painted above, rarely used).``smart header="We can pass
URLobjects to networking (and most other) methods instead of a string" We can use a
URLobject in
fetchor
XMLHttpRequest`, almost everywhere where a URL-string is expected.
Generally, the URL
object can be passed to any method instead of a string, as most methods will perform the string conversion, that turns a URL
object into a string with full URL.
## SearchParams "?..."
Let's say we want to create a url with given search params, for instance, `https://google.com/search?query=JavaScript`.
We can provide them in the URL string:
```js
new URL('https://google.com/search?query=JavaScript')
…But parameters need to be encoded if they contain spaces, non-latin letters, etc (more about that below).
So there’s a URL property for that: url.searchParams
, an object of type URLSearchParams.
It provides convenient methods for search parameters:
append(name, value)
– add the parameter by name
,delete(name)
– remove the parameter by name
,get(name)
– get the parameter by name
,getAll(name)
– get all parameters with the same name
(that’s possible, e.g. ?user=John&user=Pete
),has(name)
– check for the existence of the parameter by name
,set(name, value)
– set/replace the parameter,sort()
– sort parameters by name, rarely needed,Map
.An example with parameters that contain spaces and punctuation marks:
```js run let url = new URL(“https://google.com/search”);
url.searchParams.set(“q”, “test me!”); // added parameter with a space and !
alert(url); // https://google.com/search?q=test+me%21
url.searchParams.set(“tbs”, “qdr:y”); // added parameter with a colon :
// parameters are automatically encoded alert(url); // https://google.com/search?q=test+me%21&tbs=qdr%3Ay
// iterate over search parameters (decoded) for (let [name, value] of url.searchParams) { alert(${name}=${value}
); // q=test me!, then tbs=qdr:y } ```
There’s a standard RFC3986 that defines which characters are allowed in URLs and which are not.
Those that are not allowed, must be encoded, for instance non-latin letters and spaces - replaced with their UTF-8 codes, prefixed by %
, such as %20
(a space can be encoded by +
, for historical reasons, but that’s an exception).
The good news is that URL
objects handle all that automatically. We just supply all parameters unencoded, and then convert the URL
to string:
```js run // using some cyrillic characters for this example
let url = new URL(“https://ru.wikipedia.org/wiki/Тест”);
url.searchParams.set(“key”, “ъ”); alert(url); //https://ru.wikipedia.org/wiki/%D0%A2%D0%B5%D1%81%D1%82?key=%D1%8A
As you can see, both `Тест` in the url path and `ъ` in the parameter are encoded.
The URL became longer, because each cyrillic letter is represented with two bytes in UTF-8, so there are two `%..` entities.
### Encoding strings
In old times, before `URL` objects appeared, people used strings for URLs.
As of now, `URL` objects are often more convenient, but strings can still be used as well. In many cases using a string makes the code shorter.
If we use a string though, we need to encode/decode special characters manually.
There are built-in functions for that:
- [encodeURI](mdn:/JavaScript/Reference/Global_Objects/encodeURI) - encodes URL as a whole.
- [decodeURI](mdn:/JavaScript/Reference/Global_Objects/decodeURI) - decodes it back.
- [encodeURIComponent](mdn:/JavaScript/Reference/Global_Objects/encodeURIComponent) - encodes a URL component, such as a search parameter, or a hash, or a pathname.
- [decodeURIComponent](mdn:/JavaScript/Reference/Global_Objects/decodeURIComponent) - decodes it back.
A natural question is: "What's the difference between `encodeURIComponent` and `encodeURI`? When we should use either?"
That's easy to understand if we look at the URL, that's split into components in the picture above:
https://site.com:8080/path/page?p1=v1&p2=v2#hash ```
As we can see, characters such as :
, ?
, =
, &
, #
are allowed in URL.
…On the other hand, if we look at a single URL component, such as a search parameter, these characters must be encoded, not to break the formatting.
encodeURI
encodes only characters that are totally forbidden in URL.encodeURIComponent
encodes same characters, and, in addition to them, characters #
, $
, &
, +
, ,
, /
, :
, ;
, =
, ?
and @
.So, for a whole URL we can use encodeURI
:
```js run // using cyrillic characters in url path let url = encodeURI(“http://site.com/привет”);
alert(url); // http://site.com/%D0%BF%D1%80%D0%B8%D0%B2%D0%B5%D1%82 ```
…While for URL parameters we should use encodeURIComponent
instead:
```js run let music = encodeURIComponent(“Rock&Roll”);
let url = https://google.com/search?q=${music}
; alert(url); // https://google.com/search?q=Rock%26Roll ```
Compare it with encodeURI
:
```js run let music = encodeURI(“Rock&Roll”);
let url = https://google.com/search?q=${music}
; alert(url); // https://google.com/search?q=Rock&Roll ```
As we can see, encodeURI
does not encode &
, as this is a legit character in URL as a whole.
But we should encode &
inside a search parameter, otherwise, we get q=Rock&Roll
- that is actually q=Rock
plus some obscure parameter Roll
. Not as intended.
So we should use only encodeURIComponent
for each search parameter, to correctly insert it in the URL string. The safest is to encode both name and value, unless we’re absolutely sure that it has only allowed characters.
```smart header="Encoding difference compared to
URL" Classes [URL](https://url.spec.whatwg.org/#url-class) and [URLSearchParams](https://url.spec.whatwg.org/#interface-urlsearchparams) are based on the latest URI specification: [RFC3986](https://tools.ietf.org/html/rfc3986), while
encode*` functions are based on the obsolete version RFC2396.
There are a few differences, e.g. IPv6 addresses are encoded differently:
```js run // valid url with IPv6 address let url = “http://[2607:f8b0:4005:802::1007]/”;
alert(encodeURI(url)); // http://%5B2607:f8b0:4005:802::1007%5D/ alert(new URL(url)); // http://[2607:f8b0:4005:802::1007]/
As we can see, `encodeURI` replaced square brackets `[...]`, that's not correct, the reason is: IPv6 urls did not exist at the time of RFC2396 (August 1998).
Such cases are rare, `encode*` functions work well most of the time.

The tensor product of two vector spaces V,W over \mathbb{F} is a vector space V \otimes W over \mathbb{F} together with a bilinear map V \times W \stackrel{\otimes}{\rightarrow} V \otimes W with the property that whenever \mathcal{B}_V, \mathcal{B}_W are bases for V,W respectively, the set \{ v_i \otimes w_j \mid v_i \in \mathcal{B}_V, w_j \in \mathcal{B}_W \} gives a basis for V \otimes W.
The following theorem shows that the property in the definition need not be checked for all pairs of bases; just one pair is sufficient.
Theorem: Let Y be a vector space and \phi : V \times W \rightarrow Y be bilinear. Suppose there are bases \mathcal{B}_V, \mathcal{B}_W for V,W respectively, such that \phi(v \times w) is a basis for Y. Then the same holds for any pair of bases.
Let V, W be vector spaces over \mathbb{F}. Following (Zakharevich 2015), our goal is to construct a vector space V \otimes W such that for any vector space Z,
\mathcal{L}(V \otimes W, Z) \cong
\big\{ \substack{\text{bilinear maps}\\{V \times W \rightarrow Z}} \big\}
Let A = \mathrm{Free}(V \times W) be the free vector space over \mathbb{F} on the product V \times W. We will demonstrate that
\mathcal{L}(A,Z) \cong \big\{ \substack{\text{functions}\\{V \times W \rightarrow Z}} \big\}
For v \in V, w \in W, define the notation v \otimes w \equiv \mathbb{1}_{(v,w)} \in A. A typical vector has the form f = \sum_{k=1}^n \alpha_k (v_k \otimes w_k) \in A. By linearity, observe that each T \in \mathcal{L}(A,Z) is determined uniquely by its values on the standard basis, exposing a bijection between \mathcal{L}(A,Z) and (nonlinear) functions V \times W \rightarrow Z.
T f
= T \left( \sum_{k=1}^n \alpha_k (v_k \otimes w_k) \right)
= \sum_{k=1}^n \alpha_k T (v_k \otimes w_k)
Step 2: Since \mathcal{L}(A,Z) represents arbitrary functions, we will construct V \oplus W by shrinking A so that \mathcal{L}(V \times W, Z) represents only the bilinear maps V \times W \rightarrow Z. For example, if T \in \mathcal{L}(V \otimes W, Z) is a linear map, the following proof of bilinearity in the first argument
\begin{aligned}
T( (v_1 + v_2) \otimes w )
&= T( (v_1 \otimes w) + (v_2 \otimes w) ) \\
&= T(v_1 \otimes w) + T(v_2 \otimes w)
\end{aligned}
requires that (v_1 + v_2) \otimes w and (v_1 \otimes w) + (v_2 \otimes w) refer to the same element in V \otimes W. Starting from A, we can enforce this equivalence implicitly by defining V \otimes W to be the quotient space A / A_0, where
A_0 = \mathrm{Span}\left\{
\begin{aligned}[c]
(v_1 + v_2) \otimes w - (v_1 \otimes w) - (v_2 \otimes w) \\
v \otimes (w_1 + w_2) - (v \otimes w_1) - (v \otimes w_2) \\
(\alpha v) \otimes w - \alpha (v \otimes w) \\
v \otimes (\alpha w) - \alpha (v \otimes w)
\end{aligned}
\;\middle\vert\;
\begin{array}{l}
\alpha \in F \\ v \in V, w \in W
\end{array}
\right\}
This choice was made so that each linear map T \in \mathcal{L}(V \otimes W, Z) will satisfy
\begin{aligned}
T( (v_1 + v_2) \otimes w) &= T(v_1 \otimes w) + T(v_2 \otimes w) \\
T( v \otimes (w_1 + w_2)) &= T(v \otimes w_1) + T(v \otimes w_2) \\
T( (\alpha v) \otimes w ) &= T( \alpha ( v \otimes w) ) \\
T( v \otimes (\alpha w) ) &= T( \alpha ( v \otimes w) )
\end{aligned}
(Technically, (v \otimes w) \in V \otimes W stands for the equivalence class of v \otimes w = \mathbb{1}_{(v,w)} \in A.)
As pointed out by Purbhoo 2012, since A = \mathrm{Free}(V \times W) is the space of formal linear combinations of (v,w) pairs, A_0 is the space of those linear combinations that can be simplified to the zero vector using bilinearity. Accordingly, A / A_0 reduces A to a space where two expressions are equal iff one can be simplified to the other using bilinearity.


MARS ATTACKS! A film review by Paul W. Cashman Copyright 1996 Paul W. Cashman
Summary: see it at a matinee price; it might not be for everyone.
I'd only seen one quick ad for this film before seeing a sneak preview on December 1st, so I had few preconceptions about it. I knew that Tim Burton was involved and that it looked like a send-up of B-movies, a genre with which I'm passingly familiar, but that's about it.
For me, this film didn't -quite- work. There were some really funny moments, but many of the stereotype portrayals were a bit over the top, at least for me. Jack Nicholson turns in a truly scary performance as the President -- I'd be scared if he were in office! -- and the lampooning of various other institutions, groups and cultures continues, to the point where underneath its veneer the movie seems to be lecturing us.......
--Which would be fine if it weren't trying to be uproariously campy at the same time, and it was trying. Maybe TOO campy; some of the effects were intentionally cheesy but distracted from the flow because of that. Some scenes were so over-the-top campy that the audience could do nothing else but groan. Unfortunately, the average movie-goer won't get all the gags -- some will get fewer than half -- and so we doubted afterwards the movie would "fly."
MARS ATTACKS! includes cameo performances from a number of actors including Danny DeVito (fine if somewhat predictable, in-character as a Vegas shark) and crooner Tom Jones (also part of the Vegas scenes). No major complaints about the acting, but we wondered afterwards what some of these 'big guns' were doing in this particular film.
Overall, I thought the movie was so-so. It didn't quite work for me but for other genre fans, especially those more familiar with the lurid pulps and B-films, it might appeal more. The score, by Danny Elfman, is almost worth a matinee admission price in itself. Elfman and Burton received applause during the opening credits.
It's hard to give a best scene without revealing a spoiler, but the scene where the Easter Island statues are bowled over -- literally -- by the Martians is pretty funny. Many of the best scenes already appear in the previews, anyway.
Conclusion: see it with genre-loving friends at a matinee price. You could wait for it to come to video, but some of the effects -are- worth seeing on the large screen, and Elfman's score is worth it, too.
Rating: 6 out of 10 (but I expect a wide range here:))
