I am about to finish a travel Facebook App. The design looks promising, especially because of the info and pictures I could crawl together. Few more days and I will release a first draft. For now the answer to: "how to create your own country API?"
New here? You might want to subscribe to my blog by email or RSS.
That seemed a challenge at first, but combining 1 flat txt file and 2 APIs, I got a pretty decent database that served my purpose.
It serves the travel fans under us to browse countries, viewing nice photos of those countries, and comment on each country page as well (logged in with Facebook). If it works, and people start to add content themselves, it will become a personal experience. It starts basic, new features can always be added.
But before this could work in any way, the app has to provide some content itself. Especially with a travel / country app, photos are unmissable!
In this posts some examples how to get the data required for a country database to build a nice travel app ...
I used geonames.org to get some basic info for all ISO 2 country codes, see a list here. I found small, nice country flag gif images here (filenames match the two-char ISO2 names -> AE, DE, NL, etc.).
Lists of these parameters per country exist. We need them for the Tixik API (next step). However the lists I found (example), did not work quite well with Tixik. What worked best were the results from the worldbank API , for example: for Spain - you can make the call to get all latitudes/ longitudes for all countries with this call. Then update the DB with these values and you have a pretty nice set to work with:
Now the fun starts: photos! A travel app is about showing photos. You will see the endresult, but here is the workhorse to get to the data: Tixik. I discovered it by accident, but it has a very simple yet efficient api. Quote from Tixik: "We have hundreds of thousands of presentations with pictures and texts in multiple languages. Would you like to have some of them on your website?"
And the answer is "of course we want that!". Well, it is plain simple and now you see the "why" of the latitude and longitude of the last step: http://www.tixik.com/en/api/nearby?lat=36.106121163930377&lng=28.07762145996093&limit=10&key=demo. You can raise the limit to get more photos, the key you put in when you sign up with just your name and email. To get some nice picture (links) from Andorra click here.
When processing this info for each country, you have a database with about 10.000 pic links:
I will keep it short given the size of this post. So not all details, just the core things you need to get started. :
CREATE TABLE IF NOT EXISTS `countries` ( `id` int(11) NOT NULL AUTO_INCREMENT, `iso2` varchar(2) NOT NULL, `country` varchar(50) NOT NULL, `capital` varchar(50) NOT NULL, `area` varchar(20) NOT NULL, `population` varchar(20) NOT NULL, `continent` varchar(2) NOT NULL, `currCode` varchar(3) NOT NULL, `currName` varchar(20) NOT NULL, `phone` varchar(10) NOT NULL, `langs` varchar(2) NOT NULL, `neighbours` varchar(30) NOT NULL, `longitude` varchar(20) DEFAULT NULL, `latitude` varchar(20) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ; -- -------------------------------------------------------- -- -- Table structure for table `images` -- CREATE TABLE IF NOT EXISTS `images` ( `id` int(11) NOT NULL AUTO_INCREMENT, `country` varchar(2) NOT NULL, `name` varchar(200) NOT NULL, `tn` varchar(200) NOT NULL, `tn_big` varchar(200) NOT NULL, `created` int(11) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;
while(<>){ chomp; @arr = split(/t/, $_); $insert ="INSERT INTO countries (id, iso2, country, capital, area, population, continent, currCode, currName, phone, langs, neighbours) VALUES (NULL, '$arr[0]', '$arr[1]', '$arr[2]', '$arr[3]', '$arr[4]', '$arr[5]', '$arr[6]', '$arr[7]', '$arr[8]', '$arr[9]', '$arr[10]');"; print "$insertn"; }
Run it as $ perl test.pl country_file - it will take that file as input, loop through it, split each line into an array based on the tab character, etc.
function getLocationParamsWorldBank(){ // saved xml from http://api.worldbank.org/countries?per_page=300 $wbUrl = 'api.worldbank.countries.all.xml'; $ns='wb'; $xml = @simplexml_load_file($wbUrl); $params = array(); $counter=0; foreach($xml->children($ns,true) as $i) { $query = "UPDATE countries SET longitude='".$i->longitude."', latitude='".$i->latitude."' "; $query .= "WHERE iso2='".$i->iso2Code."';"; echo $query ."<br>"; } }
No SQL security here, because I am going to do the import myself. I can also do the import with PHP MySql commands but for this exercise I wanted to see the commands first and then copy paste. If you want to let PHP do all the work, run something like this on the $query (after having created the database $link object):
$r = $link->query($query); $returnID = $link->insert_id; if(is_numeric($returnID)) { ..
function getThumbs($country) { $params = getLocationParamsDb($country); // skipped for brevity $xml = queryTixik($params); $images = processTixikImages($xml); writeImagesToDb($country, $images); // skipped for brevity } function queryTixik($params, $limit = 50) { $latitude = $params['latitude']; // form "getLocationParamsDb" $longitude = $params['longitude']; $tixKey = "--obtain from tixik.com -- "; $txUrl = "http://www.tixik.com/en/api/nearby?lat=$latitude&lng=$longitude&limit=$limit&key=$tixKey"; $xml = simplexml_load_file($txUrl, 'SimpleXMLElement', LIBXML_NOCDATA); return $xml; } function processTixikImages($xml){ $images = array(); $i = 0; foreach ($xml->items->item as $item) { if (@fclose(@fopen($item->tn, "r")) ) { $images[$i]['name'] = str_replace("'","'",$item->name); // not screw up sql statement $images[$i]['tn'] = $item->tn; // thumbnail $images[$i]['tn_big'] = $item->tn_big; // bigger version of image $i++; } } }
I became a fan of shortening my functions. It is a good programming practice. Next time I turn the 4 functions into 8, it really makes things cleaner.
Nice trick: LIBXML_NOCDATA allows you to read the CDATA outputs (comments) which are not processed per default by simplexml_load_file. XML Tixik returns, has this occasionally so err on the safe side.
Another thing that I wanted to make sure was that each thumbnail link was actually accessible. Here is how: basically you can test for the positive return of:
if (@fclose(@fopen($item->tn, "r")) ) { .. }
Again, I skipped some details to not make this post too long. Play with it, I learned quite a bit putting myself up for this exercise. The result was worth the effort though.
OK, you might be wondering now: "the data is there, now what?!" ... I will give you a quick preview of the FB app I am building ...

A grammar files contain both terminal and nonterminal symbols. Terminals are alphabetic strings. Nonterminals are alphanumeric strings enclosed in angle brackets. For example, print, move, and select are all terminals; <commands>, <np>, and <vp> are nonterminals.
The grammar file is a set of context-free rewrite rules. Each rule contains one nonterminal symbol on the left-hand side of an equals sign ("=") and one or more terminal or nonterminal symbols on the right-hand side. Rules must end with a period ("."). Each rule must have a unique left-hand side nonterminal---no two rules can have identical left-hand sides. For example, the following grammar fragment is not allowed:
<np> = <pronoun> . <np> = <determiner> <noun> .
However, the right-hand side of a rule can contain a list of alternative rewrites delimited by the "|" character. For example, the above fragment can be rewritten as:
<np> = <pronoun> | <determiner> <noun> .(A np can be rewritten either as a pronoun or as a determiner followed by a noun)
The following symbol-final characters have special interpretations:
The left-hand-side of the first rule in your grammar defines the root nonterminal. VoiceType or other speech applications will only recognize phrases that are derived from this nonterminal. This is illustrated in the following ill-formed grammar fragment:
<move-command> = move <direction> <count> . <:select-command> = select the next <count> words . ...A speech application using this grammar will only recognize phrases derived from <move-command> (move up five, move down six, etc.). It will not recognize phrases derived from <select-command>. In fact, this grammar will generate the warning
Non-terminal defined but not referenced BNF symbol "<select-command>"when you attempt compile it. The above grammar can be corrected by adding a grammar initial root nonterminal rule as follows:
<commands> = <move-command> | <select-command> . <move-command> = move <direction> <count> . <:select-command> = select the next <count> words .
You can include an existing grammar into the grammar file you are writing by using the INCLUDE keyword on the last line of the new grammar file. For example, the line
include 'my-numbers.bnf'
will include the rules in "my-numbers.bnf" in the current grammar.
A set of commonly used integers (one through twenty, thirty, forty and fifty) can be made available to your grammar by the special command
EXTERN <Extern_counts> .
This line must be after all the grammar rules but before any include statements. The use of the of the non-terminal <Extern_counts> is explained in the section on the @count() annotation.
Comments can be included in grammar files by use of the comment marker //.
All the characters from the comment marker to the end of the line are considered to
be the comment.
Annotations
Annotations can be attached to terminal symbols. When an annotated word is recognized
both that word and its annotation are returned to the application. These annotations
may assist the application in parsing the recognized phrases.
Annotations can either be a string or a integer ranging from 0 to 65535. For example,
<september> = September:9 . <subtract> = subtract:"-" . <db-query> = list all employees:"list-employees" | show all employees:"list-employees" .
If you are writing grammars that will be used by Voice Manager, these annotations can be used to define what actions to take when a given phrase is recognized. For information on writing Voice Manager annotations see the annotations guide.
<command> = set:"[alt f]" the font to courier | set:"[alt c]" the color to blue .
is not allowed. When the speech engine recognizes "set" it doesn't know which set is intended: set:"[alt f]" or set:"[alt c]". Often this problem can be eliminated by moving the annotations rightward. Thus, the above example can be rewritten:
<command> = set the font:"[alt f]" to courier | set the color:"[alt c]" to blue .
However, this is not always possible. For example, consider the following problematic grammar:
<print-command> = print:"[ctrl p]" | print:"[ctrl p][alt e]" even pages .
This is not allowed because when the speech engine recognizes "print" it doesn't know which print is intended: print:"[ctrl p]" or print:"[ctrl p][alt e]". Moving the annotation rightward does not eliminate the problem:
<print-command> = print:"[ctrl p]" | print even:"[ctrl p][alt e]" pages .
Print is still ambiguous between print:"[ctrl p]" and print.

Between 2012 and 2018, the New York City Department of Cultural Affairs saw a steady stream of budget increases. This led to a continued increase in the amount of program funding awarded to cultural institutions across New York City—a total increase of approximately 30% over the course of six years.
The Bronx Council on the Arts, a multidisciplinary grantmaking institution, saw their awards from the Department of Cultural Affairs increase by approximately 30% over the six year period, which allowed them to distribute more grants to artists and organizations located in the Bronx and to spearhead four different grantmaking initiatives.
“It was great, but you can always use more,” says Executive Director of the Bronx Council on the Arts Viviana Bianchi.
Organizations that saw the greatest increase in funding were folk arts, visual arts & photography and literature; funding for folk arts organizations doubled during the six years.

Want To Say Hi!


MYSTERY MEN RATING: 7 / 10 --> Good movie
For more reviews and movie screensavers, visit http://www.joblo.com/
What you get when take about a dozen name-actors and slap them into a budgeted $85 Million comic-book movie with Oscar-winner Geoffrey Rush as the bad guy, and first-time movie director of Taco Bell's infamous TV Chihuahua ads, "Yo Quiero Taco Bell", at the helm? Mystery Men: The Movie, based on the Dark Horse comic book is what you get. Is it any good? Well, let's find out.
PLOT: Captain Amazing, the popular superhero known to have abolished crime in Champion City, decides to allow one of his biggest nemeses, Cassanova Frankenstein, out of the penitentiary, because he is losing his sponsors due to the lack of altercations left for him in the big city. Unfortunately for him, Cassanova has plans of his own, leaving it up to several up-and-coming, bumbling superheroes to attempt to save the day.
CRITIQUE: Mostly enjoyable and colorful comic-book hero spoof, this movie was not as funny as I anticipated, but did offer enough original material and pretty eye-candy for yours truly to be amused during its entire showing. I am also a comic book collector myself, and appreciated many at the potshots taken at the comic-book genre (Most of the funniest stuff came from this premise). I also liked the whole concept of "disco" being integrated into the bad guys' theme, as well as the quirky special effects and the few surprises tossed in and around. The actors were all passable, with William H. Macy sticking out as the cream of their crop, but I did think Ben Stiller could have been a little funnier. Also, what's with Lena Olin taking that complete throwaway role as Cassanova's bimbo-du-jour (I still have dreams about here in ROMEO IS BLEEDING... :) Garofalo was darkly humorous as per usual.
All in all, I suppose they could have done much better with such a parody film, especially in the humor and action department, but then again, some of the stories that I had heard before this screening, had me expecting the worst as well. Geoffrey Rush for one, was a definite poor casting call, simply boring me as the bad guy. They could have gotten someone with a little more charisma. And surely the "identities" of each of the Mystery Men was not as inspirational as they could have been...I mean, I know it's a parody, but the "fork-guy"? C'mon! Having said that, I think that anyone who has ever had an interest in comic books, superheroes, or even movies based on either, will enjoy this movie for what it is: a goofy, wink-wink, over-the-top, special effects-laden comic-book spoof starring a whole bunch of name-actors having a blast! Not the best movie I've seen this summer, but definitely far from the worst. Warm your nachos, and grind right into them, cause these are the kind of movies for which nachos were indirectly invented.
Little Known Facts about this film and its stars: Director Kinka Usher is best known for having directed those cute doggie commercials for Taco Bell ("Yo Quiero Taco Bell?"). Actor Ben Stiller and Janeane Garofalo once dated for about three weeks, but stopped after they thought that it was getting "weird". They are now really good friends, and seem to be in every other movie together. They even wrote a book together called "Feel This Book: An Essential Guide to Self-Empowerment, Spiritual Supremacy, and Sexual Satisfaction". Janeane was offered the role of Gale Weathers in the movie SCREAM (8/10), but turned it down to do a movie called SWEETHEARTS. Courtney Cox then got her role and SCREAM went on to gross more than $100 million, where as SWEETHEARTS went straight to video. Her production company is called "I Hate Myself Productions". She stands 5'1". One funny in-joke is contained in the line "I'm just a publicist, not a magician!", delivered by Captain Amazing's publicist near the beginning of the film. The actor delivering the line, Rickie Jay, is in actually, a magician. Greg Kinnear lived in Greece for sometime, and can actually speak Greek. Paul Reubens (AKA Pee-Wee Herman) was born Paul Rubenfield. He was once honorably discharged from the Marine Corps, and was arrested for masturbating in an adult movie theatre in 1991. Actress Lena Olin is born in Sweden, and had already made a successful career as an actress before she came to Hollywood. Director Sydney Pollack rewrote the scenario for his movie HAVANNA especially for her. The "H" in William H. Macy's name stands for Hall. Actress Louis Lasser, who plays Hank Azaria's mom in this film, was once married to director Woody Allen for about three years in the sixties. Fugee music star Pras plays one of the Disco Boys in this film. Actor Wes Studi (The Sphynx) is an American Indian of the Cherokee Nation.

| A film which marks the 50th anniversary of England's victory in the 1966 World Cup, and uncovers the truth behind the man who led them to it... Bo66y is a powerful, dramatic and deeply personal portrait of a genuine footballing icon. Moore fought many battles besides those witnessed by millions on the football field. Behind the glory lies the story of a man who faced highs and lows with the same strength and bravery. But he died young, cruelly shunned by the game and by the very people who owed him so much. The story is told by his two wives, his friends and fans, including Pele, Sir Geoff Hurst Harry Redknapp, Ray Davies, Ray Winstone and Russell Brand, and more than 30 others, whose words are mixed with as yet unseen archive footage. | |

Chapter 23: CalculusThis chapter covers J operators for differentiation and integration. It covers
23.1 DifferentiationThere is a built-in conjunction d.(lowercase d dot). Its left argument is a function to be differentiated. Its right argument is 1 if the first derivative is required, or 2 for the second derivative, and so on. The first derivative of the "cube" function ^&3 is "3 times the square".^&3 d. 1 3&*@(^&2)The general scheme is that if e is (an expression denoting) a function, then e d. n is (an expression denoting) the n'th derivative of e. Here is another example, expressing the cube function as the polynomial 0 0 0 1 & p. 0 0 0 1 &p. d. 1 0 0 3&p.Suppose we define a verb cube:
Differentiating with d., we see that the derivative is, as expected, 3-times-the-square, but the expression for the derivative is not very informative.
The reason is that cube is a name denoting a verb, and such names are in general not evaluated until the verb is applied. (See Appendix 1 .) If we want to inspect the derivative of cube, we can force evaluation of the name cube by applying the f. adverb.
Alternatively, we could force evaluation of the expression for the derivative, again by applying f.
23.2 IntegrationWith a right argument of _1, the conjunction d. integrates the left argument. The integral of "3 times the square" is "cube".0 0 3 & p. d. _1 0 0 0 1&p. 23.3 The Domain of d.Functions which are differentiable or integrable with d. must firstly be scalar. That is, they must take scalar arguments and deliver scalar results, and all intermediate quantities must be scalars. Here is an example. The function "(x-1)*(x-2)" can be written in several different ways. Here are two:
f is scalar, and in the domain of d. However, g is not scalar, because it forms the intermediate quantity x - 1 2 which is a vector. Thus g is not in the domain of d.. To demonstrate this, we force evaluation of the derivatives.
Secondly, d. can differentiate constant functions, polynomials, exponentials ^x and integral powers x^n.
If f and g are differentiable with d., then so are the forks (f+g), (f-g), (f*g) and f%g.
Trigonometric functions are differentiable with d. The derivative of the fork (sin + cos) is (cos - sin).
If f and g are differentiable with d., then so are the compositions f@g and f@:g
23.4 The Conjunction D.The conjunction D. (uppercase D dot) computes derivatives. It differs from d. in two ways.
23.4.1 The Domain of D.Since D. can use numerical methods, its arguments can be arbitrary functions. For example, recall the function g above, to compute "(x-1)*(x-2)",which was demonstrated above to be outside the domain of d. . However it is within the domain of D.. Its derivative is "2x-3"
23.4.2 Partial Derivatives with D.Next we look at functions which compute a scalar from a vector argument. For example consider a surface where the height at a point (x,y) is given by(sin x) * (cos y)The height-function, with the vector argument (x,y) might be written: h =: (sin @ {.) * (cos @ {:)The expression (h D.1)(x,y) computes the numerical values of the two slopes, in the x-direction and the y-direction, of the function h at the point (x,y).
The result p gives the values of the partial derivatives with respect to x and with respect to y. We can check this result. Suppose we define a function q say, for the height along the line y=0.5. We want q(x) to be h(x,0.5) and thus q =: h @: (, & 0.5)The idea now is that the derivative of q applied to argument x should be the same as the first partial derivative of h at x,0.5.
Now we look at partial derivatives of functions which compute vectors from vectors. Here is an example, a function which takes the point (x,y,z) in 3-space to the point (2x,3y) in 2-space.
In general such a function will take an argument-vector of length m and produce a result-vector of length n. Hence there will be m*n partial derivatives, one for each element of the result with respect to each element of the argument. The six partial derivatives of foo at the point xyz = 1 1 1 are shown by:
Consider now a function such as cube which produces scalars from scalars. Given a vector argument, it will produce a vector result of the same length, where an element of the result depends only on the corresponding element of the argument.
Therefore, for a scalar function, all partial derivatives are zero except those for elements of the result with respect to the corresponding elements of the argument.
If a scalar function is given in fully-evaluated form, and is in the domain of d., the D. conjunction will produce an analytic expression for the partial derivatives function:
23.5 Numerical IntegrationThere is a library script-file called integrat.ijs . It contains several different operators for integration. Documentation is given in the script file.It can be be downloaded from the JSoftware website: here is a link to integrat.ijs Assuming that we have downloaded into a directory, say C:\temp for example, then we load it into the J session with: load 'c:\temp\integrat.ijs'One of the integration operators provided is the conjunction adapt ("numeric integration by adaptive quadrature"). The expression f adapt (L,U) computes the numeric value of the definite integral of f between limits L and U. For example, we expect the integral of 3&* between 0 and 1 to be 1.5
This is the end of Chapter 23. |

While I witnessed my first ever snow. There is another interesting phenomenon happens at the same time. Due to the special order of weather which a heavy was first poured then followed by a drastic rapid cooling, everything is coated in crystal-clear ice layer.
I called this sugar-coated haw phenomenon. Sugar-coated haw is a famous Chinese snack and is one of my favorite foods. Take a look at the snack itself below.
看到初学之时也见到了有趣的现象。由于老天先是写了场大雨，然后马上急速降温，造成了世间一切全包裹在亮晶晶的冰层里。
我管这现象叫冰糖葫芦现象。这不得不说冰糖葫芦是我在中国最喜欢吃的零食之一，如果不知道是什么请看下图。
Isn’t it nice to look? I can tell you with the full responsibility that they are great to eat too! Best to serve with the sugar coat frozen.
The mother nature just coated everything on the street the same way using ice.
是不是看着就想流口水的感觉？可以负全责的告诉你它们不只好看还很好吃！冰冻了再吃口感更是上佳。
大自然用同样的方法在街上制造了各种冰糖葫芦。
Lovely to see but a total nightmare to live in such environment. We can barely walk on the sugar-coated walkway. The locals must hope the ice to melt down soon.
一切都是晶莹剔透，多么可爱好看的景象。但是仅止于好看而已，生活在这样的环境可是很不方便的。我们有好几次就几乎摔倒在冰糖路上面了，想必当地人恨不得它们快点融化吧。

SpriteSpin is a jQuery plugin that turns image frames into animations. It requires an array of images or a stiched sprite sheet and plays them frame by frame like a flip book. The aim of this plugin is to provide a 360 degree view of any kind of product.
The plugin is built with extensibility in mind and allows web developers to customize the behavior and presentation of the animations.
SpriteSpin depends on the jQuery-1.4.2 framework and later. Although the basic usability is straight forward a bit of javascript knowledge is required.

DESKTOP-FILE-INSTALL(1) DESKTOP-FILE-INSTALL(1) NAME desktop-file-install, desktop-file-edit - Installation and edition of desktop files SYNOPSIS desktop-file-install [--dir=DIR] [-m MODE|--mode=MODE] [--vendor=VENDOR] [--delete-original] [--rebuild-mime-info-cache] [EDITOPTION]... FILE... desktop-file-edit [EDITOPTION]... FILE DESCRIPTION The desktop-file-install program is a tool to install, and optionally edit, desktop files. The desktop-file-edit program is a tool to edit a desktop file. They are mostly useful for developers and packagers. Various options are available to edit the desktop files. The edit options can be specified more than once and will be processed in the same order as the options passed to the program. desktop-file-install and desktop-file-edit will always try to validate the resulting desktop file. A failure to validate might lead to the abor‐ tion of the installation of the desktop files. The list of registered categories and desktop environments is defined in the Menu specification: http://freedesktop.org/wiki/Specifications/menu- spec. OPTIONS The following options are supported: --dir=DIR Install desktop files to the DIR directory. -m, --mode=MODE Set the permissions of the destination files to MODE. --vendor=VENDOR Add a vendor prefix to the desktop files. If a file already has this prefix, nothing happens; else, the file will be named VENDOR- FILE. For example: if VENDOR is freedesktop.org and FILE is speci‐ fication.desktop, the result file will be freedesktop.org-specifi‐ cation.desktop. --delete-original Delete the source desktop files, leaving only the target files. Effectively "renames" the desktop files. --rebuild-mime-info-cache Rebuild the MIME types application database after installing the desktop files. See update-desktop-database(1) for information about this database. EDIT OPTIONS The following edit options are supported: --set-key=KEY Set the KEY key to the value passed to the next --set-value option. A matching --set-value option is mandatory. --set-value=VALUE Set the key specified with the previous --set-key option to VALUE. A matching --set-key option is mandatory. --set-name=NAME Set the name (key Name) to NAME. If a name was already set, it will be overridden. Localizations of the old name will be removed. --copy-name-to-generic-name Copy the value of the Name key to the GenericName key. Note that a desktop file requires a Name key to be valid, so this option will always have an effect. --set-generic-name=GENERIC-NAME Set the generic name (key GenericName) to GENERIC-NAME. If a generic name was already set, it will be overridden. Localizations of the old generic name will be removed. --copy-generic-name-to-name Copy the value of the GenericName key to the Name key, if the GenericName key is present. --set-comment=COMMENT Set the comment (key Comment) to COMMENT. If a comment was already set, it will be overridden. Localizations of the old comment will be removed. --set-icon=ICON Set the icon (key Icon) to ICON. If an icon was already set, it will be overridden. Localizations of the old icon will be removed. --add-category=CATEGORY Add CATEGORY to the list of categories (key Categories). If CATE‐ GORY was already present in the list, this operation is a no-op. A non-registered category should be prefixed with X-. --remove-category=CATEGORY Remove CATEGORY from the list of categories (key Categories). If CATEGORY was not present in the list, this operation is a no-op. --add-mime-type=MIME-TYPE Add MIME-TYPE to the list of MIME types (key MimeType). If MIME- TYPE was already present in the list, this operation is a no-op. --remove-mime-type=MIME-TYPE Remove MIME-TYPE from the list of MIME types (key MimeType). If MIME-TYPE was not present in the list, this operation is a no-op. --add-only-show-in=ENVIRONMENT Add ENVIRONMENT to the list of desktop environments where the desktop files should be displayed (key OnlyShowIn). If ENVIRONMENT was already present in the list, this operation is a no-op. A non- registered desktop environment should be prefixed with X-. Note that an empty OnlyShowIn key in a desktop file means that the desktop file will be displayed in all environments. --remove-only-show-in=ENVIRONMENT Remove ENVIRONMENT from the list of desktop environments where the desktop files should be displayed (key OnlyShowIn). If ENVIRONMENT was not present in the list, this operation is a no-op. --add-not-show-in=ENVIRONMENT Add ENVIRONMENT to the list of desktop environments where the desktop files should not be displayed (key NotShowIn). If ENVIRON‐ MENT was already present in the list, this operation is a no-op. A non-registered desktop environment should be prefixed with X-. Note that an empty NotShowIn key in a desktop file means that the desktop file will be displayed in all environments. --remove-not-show-in=ENVIRONMENT Remove ENVIRONMENT from the list of desktop environments where the desktop files should not be displayed (key NotShowIn). If ENVIRON‐ MENT was not present in the list, this operation is a no-op. --remove-key=KEY Remove the KEY key from the desktop files, if present. ENVIRONMENT Some environment variables change the behavior of desktop-file-install: DESKTOP_FILE_VENDOR This variable can be used as an alternative to the --vendor option. If the --vendor option is used, this environment variable will be ignored. DESKTOP_FILE_INSTALL_DIR This variable can be used as an alternative to the --dir option. If the --dir option is used, this environment variable will be ignored. RPM_BUILD_ROOT This variable is set when building RPM packages. If the --dir option and the DESKTOP_FILE_INSTALL_DIR environment variable are not used, it will automatically be prepended to the default install directory to install the desktop files appropriately when building packages. BUGS If you find bugs in the desktop-file-install program, please report these on https://bugs.freedesktop.org.

Eco DC is the first conference intersecting design with climate issues. It will be held in April 2020, the weekend before Earth Day.
Our goal is simple. We aim to empower designers to be the change we need in a world galvanized to action on environmental issues. From effective visual communication that empowers individuals to how the design process itself can be changed, this conference will give you new ideas on sustainable practices.
We hope you will come in with an open mind and your own creative solutions on how you can impact your community and give back to the earth. See you there!
The conference focuses on the central message of designers being a ripple for change. As Tim Cook once said, "you want to be the pebble in the pond that creates the ripple for change". Our conference wants to recognize the feats that designers and individuals accomplish each day to make a better world. We also want to instill the passion and ideas that design and environment can come together. Design looks at visual communication and enhances how society interacts with the world around them. So why not take that a step further and make sure that we keep sustainability and environmental concerns in mind?
This is why we want designers and emerging leaders like yourself to take that small step. Be the one that starts a wave of change. Be the one that stands out in a crowd and stand for what you believe in. We need people like you to answer the environmental challenges the world is -- and will -- be facing.
The conference will be held at the Capitol View Conference Center. Participants will be located just a few blocks from the Capitol and can experience all that DC has to offer.
For any questions, please call us at<PHONE_NUMBER>. We hope to see you there!


The Grid
I’m finally able to share that I recently joined The Grid!
I feel proud to be a part of the team behind GSS, NoFlo, FlowHub, and more.
Backing the Future
I first encountered The Grid last year when I backed the NoFlo Development Environment on Kickstarter, and again a few months ago after working with Auto Layout on iOS.
GSS brings the constraint-solving Autolayout in iOS to the browser: http://t.co/DxUDiuvnYj - center any element in another with a one-liner
— Addy Osmani (@addyosmani) March 7, 2014
At that time I was frustrated with web development and had sought refuge in producing native applications. Underwhelmed by the current landscape, I wondered if I’d ever go back.
I kept dreaming of a world I thought I’d never see. And then, one day… I got in. - Tron Legacy
The Grid changed all of that. Here are just a few reasons why I’m excited about what we’re doing:

We’re a distributed team comprised of people across 7 countries. I love that our culture supports working remotely where geography isn’t a barrier to working with great people. Everyone I’ve come into contact with has been incredibly talented and humble.
Style & Substance
Design is given the attention it deserves. In conjunction with the innovative technology required to make them a reality, beautiful aesthetics are at the forefront of everything we do.
Open Source
Just take a look at one or two of our organizations on GitHub and it’s easy to see that we believe in open source. I’m a big proponent for writing software in an open source environment that encourages collaboration and produces more modular, testable code with better documentation.
A Digital Frontier
Years of development have been invested into projects like these to facilitate building our platform, which launches soon.
I’m continually blown away by what we’re doing and I can’t wait for everyone else to experience it too.
