From here you can add and edit cards.\n\n![Card UI](screenshots/cards_ui-1467754141259.png)\n\n---\n\nThe front of a General flash card.\n\n![Memorizing general knowledge](screenshots/memorize_ui-1467754306971.png)\n\n---\n\nThe reverse (answer side) of a Code flash card.\n\n![Code view](screenshots/memorize_code-1467754962142.png)\n\n## Important Note\n\nThe set included in this project (**cards-jwasham.db**) is not my full set, and is way too big already.\n\nThanks for asking for my list of 1,792 cards. But **it’s too much.** I even printed them out. It’s 50 pages, front and back, in tiny text. It would take about 8 hours to just read them all.\n\nMy set includes a lot of obscure info from books I’ve read, Python trivia, machine learning knowledge, assembly language, etc.\n\nI've added it to the project if you want it (**cards-jwasham-extreme.db**). You've been warned.\n\nPlease make your own set, and while you’re making them, only make cards for what you need to know. Otherwise, it gets out of hand.\n\n## How to convert to Anki or CSV\n\nIf you don't want to run a server, you can simply use Anki or a similar service/app. Use this script to convert from my sets (SQLite .db file), or yours, to CSV:\n\nhttps://github.com/eyedol/tools/blob/master/anki_data_builder.py\n\nThanks [@eyedol](https://github.com/eyedol)\n\n## Anki Flashcards:\n\n* [computer science flash cards - (basic)](https://ankiweb.net/shared/info/1782040640)\n* [computer science flash cards - (extreme)](https://ankiweb.net/shared/info/1691396127)\n\nThanks [@JackKuo-tw](https://github.com/JackKuo-tw)\n\n## How to run it on a server\n\n1. Clone project to a directory on your web server.\n1. Edit the config.txt file. Change the secret key, username and password. The username and password will be the login\n for your site. There is only one user - you.\n1. Follow this long tutorial to get Flask running. It was way more work than it should be:\n https://www.digitalocean.com/community/tutorials/how-to-serve-flask-applications-with-uwsgi-and-nginx-on-ubuntu-16-04\n - `wsgi.py` is the entry point. It calls `flash_cards.py`\n - This is my systemd file `/etc/systemd/system/flash_cards.service`: [view](flash_cards.service)\n - you can see the paths where I installed it, and the name of my virtualenv directory\n - when done with tutorial:\n ```shell\n sudo systemctl restart flash_cards\n sudo systemctl daemon-reload\n ```\n1. When you see a login page, you're good to go.\n1. Log in.\n1. Click the \"General\" or \"Code\" button and make a card!\n1. When you're ready to start memorizing, click either \"General\" or \"Code\"\n in the top menu.\n\n## How to run it on local host (Quick Guide)\n\n*Provided by [@devyash](https://github.com/devyash) - devyashsanghai@gmail.com - Reach out to this contributor if you have trouble.*\n\n1. Install dependencies:\n 1. Install [Python](https://www.python.org/download/releases)\n 1. Add python as environment variable [windows](http://stackoverflow.com/questions/3701646/how-to-add-to-the-pythonpath-in-windows-7)\n 1. To install pip, securely download [get-pip.py](https://bootstrap.pypa.io/get-pip.py)\n 1. Run `python get-pip.py` in terminal\n 1. Add pip to your PATH system variable [windows](https://stackoverflow.com/questions/23708898/pip-is-not-recognized-as-an-internal-or-external-command)\n 1. Run `pip install -r requirements.txt` in terminal after going to correct folder\n1. Type `python flash_cards.py` - if you get error for flask then use `python -m pip install Flask` first then run `flash_card.py` file\n1. Open localhost:5000/\n1. Login using 'admin' and 'default' for the username and password, respectively.\n\n**NOTE:** If you wish to use John's flash cards then also do following steps:\n\n1. Copy db files such as `cards-jwasham-extreme` OR `cards-jwasham` and paste them in db folder\n1. Edit file `flash_cards.py` line 8 and replace 'cards.db' with any of the other database files e.g.('cards-jwasham.db') \n1. Repeat the above steps from step 3\n\nEvery time you wish to run your db just open folder in terminal and run `python flash_cards.py`\n\n## How to run with Docker\n\n*Provided by [@Tinpee](https://github.com/tinpee) - tinpee.dev@gmail.com - Reach out to this contributor if you have trouble.*\n\n__Make sure you already installed [docker](https://www.docker.com) and optionally [docker-compose](https://docs.docker.com/compose/install/)__\n\n1. Clone project to any where you want and go to source folder.\n1. Edit the `config.txt` file. Change the secret key, username and password. The username and password will be the login for your site. There is only one user - you.\n1. Build image:\n - Docker: `docker build . -t cs-flash-cards`\n - Compose: `docker-compose build`\n1. Run container:\n - Docker: `docker run -d -p 8000:8000 --name cs-flash-cards cs-flash-cards`\n - Compose: `docker-compose up`\n1. Go your browser and type `http://localhost:8000`\n\n__If you already had a backup file `cards.db`. Run following command:__\n\n*Note: We don't need to rebuild image, just delete old container if you already built.*\n\n```shell\ndocker run -d -p 8000:8000 --name cs-flash-cards -v :/src/db cs-flash-cards\n```\n\n- ``: is the full path contains `cards.db`.\n- Example: `/home/tinpee/cs-flash-cards/db`, and `cards.db` is inside this folder.\n\nFor convenience, if you don't have `cards.db`, this container will auto copy a new one from `cards-empty.db`.\n\n---\n\n### How to backup data ?\nWe just need store `cards.db` file, and don't need any sql command.\n- If you run container with `-v :/src/db` just go to `folder_db` and store `cards.db` anywhere you want.\n- Without `-v flag`. Type: `docker cp :/src/db/cards.db /path/to/save`\n\n### How to restore data ?\n- Delete old container (not image): `docker rm cs-flash-cards`\n- Build a new one with `-v flag`:\n`docker run -d -p 8000:8000 --name cs-flash-cards -v :/src/db cs-flash-cards`\n- Voila :)\n\n### How to deploy docker file on heroku\n\n- first install [heroku CLI](https://devcenter.heroku.com/articles/heroku-cli)\n- change `entrypoint.sh`\n\n```shell\n- export CARDS_SETTINGS=/src/config.txt\ngunicorn --bind 0.0.0.0:$8000 flash_cards:app\n+ export CARDS_SETTINGS=/src/config.txt\ngunicorn --bind 0.0.0.0:$PORT flash_cards:app\n```\n- deploy docker file with following commands\n\n```shell\nheroku login\nheroku container:login\nheroku create\n# Creating app... done, ⬢ your-app-name\nheroku container:push web --app your-app-name\nheroku container:release web --app your-app-name\nheroku open --app your-app-name\n```\n\n## Alternative for Node fans\n\n[@ashwanikumar04](https://github.com/ashwanikumar04) put together an alternative flash cards site running Node: https://github.com/ashwanikumar04/flash-cards\n\nCheck out the demo!\n\n*Happy learning!*\n" }, { "path": "config.txt", "content":

Copyright and Similar Rights means copyright and/or similar rights\n closely related to copyright including, without limitation,\n performance, broadcast, sound recording, and Sui Generis Database\n Rights, without regard to how the rights are labeled or\n categorized. For purposes of this Public License, the rights\n specified in Section 2(b)(1)-(2) are not Copyright and Similar\n Rights.\n\n e. Effective Technological Measures means those measures that, in the\n absence of proper authority, may not be circumvented under laws\n fulfilling obligations under Article 11 of the WIPO Copyright\n Treaty adopted on December 20, 1996, and/or similar international\n agreements.\n\n f. Exceptions and Limitations means fair use, fair dealing, and/or\n any other exception or limitation to Copyright and Similar Rights\n that applies to Your use of the Licensed Material.\n\n g. License Elements means the license attributes listed in the name\n of a Creative Commons Public License. The License Elements of this\n Public License are Attribution and ShareAlike.\n\n h. Licensed Material means the artistic or literary work, database,\n or other material to which the Licensor applied this Public\n License.\n\n i.

Subject to the terms and conditions of this Public License,\n the Licensor hereby grants You a worldwide, royalty-free,\n non-sublicensable, non-exclusive, irrevocable license to\n exercise the Licensed Rights in the Licensed Material to:\n\n a. reproduce and Share the Licensed Material, in whole or\n in part; and\n\n b. produce, reproduce, and Share Adapted Material.\n\n 2. Exceptions and Limitations. For the avoidance of doubt, where\n Exceptions and Limitations apply to Your use, this Public\n License does not apply, and You do not need to comply with\n its terms and conditions.\n\n 3. Term. The term of this Public License is specified in Section\n 6(a).\n\n 4. Media and formats; technical modifications allowed. The\n Licensor authorizes You to exercise the Licensed Rights in\n all media and formats whether now known or hereafter created,\n and to make technical modifications necessary to do so. The\n Licensor waives and/or agrees not to assert any right or\n authority to forbid You from making technical modifications\n necessary to exercise the Licensed Rights, including\n technical modifications necessary to circumvent Effective\n Technological Measures. For purposes of this Public License,\n simply making modifications authorized by this Section 2(a)\n (4) never produces Adapted Material.\n\n 5. Downstream recipients.\n\n a. Offer from the Licensor -- Licensed Material. Every\n recipient of the Licensed Material automatically\n receives an offer from the Licensor to exercise the\n Licensed Rights under the terms and conditions of this\n Public License.\n\n b. Additional offer from the Licensor -- Adapted Material.\n Every recipient of Adapted Material from You\n automatically receives an offer from the Licensor to\n exercise the Licensed Rights in the Adapted Material\n under the conditions of the Adapter's License You apply.\n\n c. No downstream restrictions. You may not offer or impose\n any additional or different terms or conditions on, or\n apply any Effective Technological Measures to, the\n Licensed Material if doing so restricts exercise of the\n Licensed Rights by any recipient of the Licensed\n Material.\n\n 6. No endorsement. Nothing in this Public License constitutes or\n may be construed as permission to assert or imply that You\n are, or that Your use of the Licensed Material is, connected\n with, or sponsored, endorsed, or granted official status by,\n the Licensor or others designated to receive attribution as\n provided in Section 3(a)(1)(A)(i).\n\n b. Other rights.\n\n 1. Moral rights, such as the right of integrity, are not\n licensed under this Public License, nor are publicity,\n privacy, and/or other similar personality rights; however, to\n the extent possible, the Licensor waives and/or agrees not to\n assert any such rights held by the Licensor to the limited\n extent necessary to allow You to exercise the Licensed\n Rights, but not otherwise.\n\n 2. Patent and trademark rights are not licensed under this\n Public License.\n\n 3. To the extent possible, the Licensor waives any right to\n collect royalties from You for the exercise of the Licensed\n Rights, whether directly or through a collecting society\n under any voluntary or waivable statutory or compulsory\n licensing scheme. In all other cases the Licensor expressly\n reserves any right to collect such royalties.\n\n\nSection 3 -- License Conditions.\n\nYour exercise of the Licensed Rights is expressly made subject to the\nfollowing conditions.\n\n a. Attribution.\n\n 1. If You Share the Licensed Material (including in modified\n form), You must:\n\n a. retain the following if it is supplied by the Licensor\n with the Licensed Material:\n\n i. identification of the creator(s) of the Licensed\n Material and any others designated to receive\n attribution, in any reasonable manner requested by\n the Licensor (including by pseudonym if\n designated);\n\n ii. a copyright notice;\n\n iii. a notice that refers to this Public License;\n\n iv. a notice that refers to the disclaimer of\n warranties;\n\n v. a URI or hyperlink to the Licensed Material to the\n extent reasonably practicable;\n\n b. indicate if You modified the Licensed Material and\n retain an indication of any previous modifications; and\n\n c. indicate the Licensed Material is licensed under this\n Public License, and include the text of, or the URI or\n hyperlink to, this Public License.\n\n 2. You may satisfy the conditions in Section 3(a)(1) in any\n reasonable manner based on the medium, means, and context in\n which You Share the Licensed Material. For example, it may be\n reasonable to satisfy the conditions by providing a URI or\n hyperlink to a resource that includes the required\n information.\n\n 3. If requested by the Licensor, You must remove any of the\n information required by Section 3(a)(1)(A) to the extent\n reasonably practicable.\n\n b. ShareAlike.\n\n In addition to the conditions in Section 3(a), if You Share\n Adapted Material You produce, the following conditions also apply.\n\n 1. The Adapter's License You apply must be a Creative Commons\n license with the same License Elements, this version or\n later, or a BY-SA Compatible License.\n\n 2. You must include the text of, or the URI or hyperlink to, the\n Adapter's License You apply. You may satisfy this condition\n in any reasonable manner based on the medium, means, and\n context in which You Share Adapted Material.\n\n 3. You may not offer or impose any additional or different terms\n or conditions on, or apply any Effective Technological\n Measures to, Adapted Material that restrict exercise of the\n rights granted under the Adapter's License You apply.\n\n\nSection 4 -- Sui Generis Database Rights.\n\nWhere the Licensed Rights include Sui Generis Database Rights that\napply to Your use of the Licensed Material:\n\n a. for the avoidance of doubt, Section 2(a)(1) grants You the right\n to extract, reuse, reproduce, and Share all or a substantial\n portion of the contents of the database;\n\n b. if You include all or a substantial portion of the database\n contents in a database in which You have Sui Generis Database\n Rights, then the database in which You have Sui Generis Database\n Rights (but not its individual contents) is Adapted Material,\n\n including for purposes of Section 3(b); and\n c. You must comply with the conditions in Section 3(a) if You Share\n all or a substantial portion of the contents of the database.\n\nFor the avoidance of doubt, this Section 4 supplements and does not\nreplace Your obligations under this Public License where the Licensed\nRights include other Copyright and Similar Rights.\n\n\nSection 5 -- Disclaimer of Warranties and Limitation of Liability.\n\n a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE\n EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS\n AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF\n ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,\n IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,\n WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR\n PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,\n ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT\n KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT\n ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.\n\n b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE\n TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,\n NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,\n INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,\n COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR\n USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN\n ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR\n DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR\n IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.\n\n c. The disclaimer of warranties and limitation of liability provided\n above shall be interpreted in a manner that, to the extent\n possible, most closely approximates an absolute disclaimer and\n waiver of all liability.\n\n\nSection 6 -- Term and Termination.\n\n a. This Public License applies for the term of the Copyright and\n Similar Rights licensed here. However, if You fail to comply with\n this Public License, then Your rights under this Public License\n terminate automatically.\n\n b. Where Your right to use the Licensed Material has terminated under\n Section 6(a), it reinstates:\n\n 1. automatically as of the date the violation is cured, provided\n it is cured within 30 days of Your discovery of the\n violation; or\n\n 2. upon express reinstatement by the Licensor.\n\n For the avoidance of doubt, this Section 6(b) does not affect any\n right the Licensor may have to seek remedies for Your violations\n of this Public License.\n\n c. For the avoidance of doubt, the Licensor may also offer the\n Licensed Material under separate terms or conditions or stop\n distributing the Licensed Material at any time; however, doing so\n will not terminate this Public License.\n\n d. Sections 1, 5, 6, 7, and 8 survive termination of this Public\n License.\n\n\nSection 7 -- Other Terms and Conditions.\n\n a. The Licensor shall not be bound by any additional or different\n terms or conditions communicated by You unless expressly agreed.\n\n b. Any arrangements, understandings, or agreements regarding the\n Licensed Material not stated herein are separate from and\n independent of the terms and conditions of this Public License.\n\n\nSection 8 -- Interpretation.\n\n a. For the avoidance of doubt, this Public License does not, and\n shall not be interpreted to, reduce, limit, restrict, or impose\n conditions on any use of the Licensed Material that could lawfully\n be made without permission under this Public License.\n\n b. To the extent possible, if any provision of this Public License is\n deemed unenforceable, it shall be automatically reformed to the\n minimum extent necessary to make it enforceable. If the provision\n cannot be reformed, it shall be severed from this Public License\n without affecting the enforceability of the remaining terms and\n conditions.\n\n c. No term or condition of this Public License will be waived and no\n failure to comply consented to unless expressly agreed to by the\n Licensor.\n\n d. Nothing in this Public License constitutes or may be interpreted\n as a limitation upon, or waiver of, any privileges and immunities\n that apply to the Licensor or You, including from the legal\n processes of any jurisdiction or authority.\n\n\n=======================================================================\n\nCreative Commons is not a party to its public\nlicenses.
