Last week the world celebrated Safer Internet Day, a day used to call upon stakeholders to join together to make the internet a safer and better place for all, and especially for children and young people. Here at Flickr, we believe in creating spaces on the internet that take into account the safety of all of our contributors, especially our youngest and most underrepresented. So, to celebrate that and to continue the work of making our spaces safer and more accessible to all, we have added a code of conduct to our most trafficked open source repositories on GitHub.
Open source is a method of development that allows software to be available publicly so that contributors can modify, add, and remove code as they see fit in order to create a more robust codebase colored with the ideas and innovations of many developers rather than just a few. At Flickr we believe that innovation happens when we have a diverse and widespread set of voices coming together to suggest changes. Open source allows us to harness the power of these voices to create the very best software we can.
Codes of conduct are extremely common and important in the open source community. Groups like Linux, Homebrew, Bootstrap, and Kubernetes all have codes of conduct governing the use of and contributions to their open source projects. Because open source allows such a diverse set of voices to express themselves, conflicts can arise and unfortunately not all come with the best of intent.
In order to protect underrepresented groups and to foster a strong and healthy open source community here at Flickr, we thought about whether it would be best to write our own code of conduct specifically tailored to what we value at Flickr or whether it would be better to find a code of conduct already in use that we could use to guide our own open source communities. We ended up finding a code of conduct already in use by quite a few well respected organizations that directly spoke to our most important operating principles.
Contributor Covenant is a code of conduct for participating in open source communities which explicitly outlines expectations in order to create a healthy open source culture. Contributor Covenant has been adopted by over a hundred thousand open source communities and projects since 2014 and is used by Linux, Babel, Bootstrap, Kubernetes, code.gov, Twilio, Homebrew-Cask, and Target to name a few. With such well-respected organizations turning to Contributor Covenant, it was something we thought we would be foolish not to consider.
As we considered, we realized that Contributor Covenant had all of our values specified in a wonderful document that was only a little over a page long. Both accessible in its readability and shortness and robust enough to do the job of protecting underrepresented contributors on our open source repositories, we had found a perfect marriage of all of the things that we wanted in a code of conduct, while also allowing us to become part of a large scale community adopting a singular vision for a healthy, safe, and innovational open source community.
To make this process repeatable, we adopted a hybrid approach where I added the Flickr-specific transformations of the API as a plugin in a newly created Akita open source repository. (You can check out the code here!) Akita will compile that plugin in all their future CLI builds so there would be no problem with dynamic loading. I can enable the plugin for my traces with a command-line flag and use the most recent version of the CLI without recompiling my plugin to match. This is the same way Akita incorporates modules for type inference. Other users can incorporate contributions in a similar way.
Prior to his arrival at Camp Elliott, Johnston sent a preliminary report to Major Jones and Maj. Gen. Clayton B. Vogel, the commanding general of the Amphibious Corps, Pacific Fleet, that explained the many reasons he believed that the Navajo offered the best possibility for recruitment as signalmen. Included in the report was a description of Johnston's own knowledge of the Navajo gained through his childhood experiences, general background information on the status of Native Americans that gave population statistics, and a specific explanation of the potential of the Navajo language as a military code. It stressed the complexity of the Navajo language and the fact that it remained mostly "'unwritten' because an alphabet or other symbols of purely native origin" did not exist, with the exception of adaptations by American scholars, anthropologists, and Franciscan Fathers, who compiled a Navajo dictionary. Furthermore, the report noted that the languages of Native American tribes varied so significantly that one group of Native Americans could not understand another's language.
Despite these objections, the initial recruitment of code talkers was approved, with the stipulation that the Navajo meet the normally required qualifications for enlistment, undergo the same seven-week training as any other recruit, and meet strict linguistic qualifications in English and Navajo, qualifications not easily attained. On May 5, 1942, the first 29 Navajos arrived at the Recruit Depot in San Diego, California, for basic training, where they trained in the standard procedures of the military and in weapons use. Afterward, they moved to Fleet Marine Force Training Center at Camp Elliott, where they received special courses in the transmission of messages and instruction in radio operation.
The Navajo soon demonstrated their ability to memorize the code and to send messages under adverse conditions similar to military action, successfully transmitting the code from planes, tanks, or fast-moving positions. The program was deemed so successful that an additional two hundred Navajos were recommended for recruitment as messengers on July 20, 1942. This prompted Philip Johnston to offer his services as a staff sergeant to aid in the development of the code talker program. On October 2, 1942, Johnston enlisted and began training his first class in November and spent the remainder of the war training additional Navajo recruits. After the new recruits went through the Marine Corps' basic training course, they came to Johnston for what he termed an "extremely intensive" eight-week messenger training course.
With the recruitment and training program for the code talkers facing curtailment on the homefront, the Navajo code talkers assigned to the South Pacific experienced their own varying degrees of success. The official Marine Corps records contain very few battle reports related to the Navajo code talkers, citing activity only at Guam, Palau, Okinawa and Iwo Jima. Reports from Iwo Jima, typical of those related to code talkers from the front, highlight both the limitations and the strengths of the program. One of the primary limitations was the aforementioned lack of available qualified Navajos to participate. Many offices, regiments, and battalions remained without new recruits, which of course rendered communication in code between these offices and those with the code talkers impossible. Recommendations called for drastic increases in the number of recruits. The limited recruiting successes, however, made following through with these recommendations difficult.
Codebook for the 2019 Survey of Consumer FinancesThe codebook contains the text, variable names, and responses for the questions asked in the survey. Also provided are a brief summary of the technical features of the survey design; a copy of the source code for the CAPI program, a concordance of variable names in the final data set and those used in the CAPI program; two programs that calculate standard errors for regression models and another program to calculate standard errors for simple statistics such as weighted medians, all three of which account for sampling error and multiple imputation; and a list of the variables included in the public data set.
MR Interview (r) Computer Code used for Computer-Assisted Personal Interviewing (CAPI)The 2019 survey data were collected using CAPI. A copy of the source code for the program is provided below. In previous years of the SCF, an executable version of the CAPI program has been provided, but for 2019, only a text version of the program code is available. Right click and choose save, then change the file extension to .mdd and this should allow licensed users of MR Interview to use the file with the software.
Developing android projects plays a vital role in the life of an android developer because android development projects, ranging from beginner to advanced level, are not only the best but also the easiest way to learn android. All you need to develop an Android application is the basic know-how and the understanding of the languages Java and Kotlin. Earlier Java was the official language for Android which changed to Kotlin in 2017. But you can use any of the languages to build android applications. So before you get a hands-on experience of the real world, start with some sample android projects to get the gist of what goes into creating and executing them. Following in the article are the top 15 android projects along with their source code that you must take up in order to polish your skills.
