Today on Elixir Wizards, Wojtek Mach of HexPM and Amal Hussein, engineering leader and former NPM team member, join Owen Bickford to compare notes on package management in Elixir vs. JavaScript. This lively conversation covers everything from best practices for dependency management to API design, SemVer (semantic versioning), and the dark ages of web development before package managers existed. The guests debate philosophical differences between the JavaScript and Elixir communities. They highlight the JavaScript ecosystem's maturity and identify potential areas of improvement, contrasted against Elixir's emphasis on minimal dependencies. Both guests encourage engineers to publish packages, even small ones, as a learning opportunity. Topics discussed in this episode: Leveraging community packages rather than reinventing the wheel Vetting packages carefully before adopting them as dependencies Evaluating security, performance, and bundle size when assessing packages Managing transitive dependencies pulled in by packages Why semantic versioning is difficult to consistently enforce Designing APIs with extensibility and backward compatibility in mind Using tools like deprecations to avoid breaking changes in new releases JavaScript's preference for code reuse over minimization The Elixir community's minimal dependencies and avoidance of tech debt Challenges in early package management, such as global dependency Learning from tools like Ruby Gems and Bundler to improve experience How log files provide visibility into dependency management actions How lock files pin dependency versions for consistency Publishing packages democratizes access and provides learning opportunities Linting to enforce standards and prevent certain bugs Primitive-focused packages provide flexibility over highly opinionated ones Suggestions for improving documentation and guides Benefits of collaboration between programming language communities Links mentioned in this episode: Node.js https://github.com/nodejs npm JavaScript Package Manager  https://github.com/npm JS Party Podcast https://changelog.com/jsparty Dashbit https://dashbit.co/ HexPM Package Manager for Erlang https://hex.pm/ HTTP Client for Elixir https://github.com/wojtekmach/req Ecto Database-Wrapper for Elixir https://github.com/elixir-ecto (Not an ORM) XState Actor-Based State Management for JavaScript https://xstate.js.org/docs/ Supply Chain Protection for JavaScript, Python, and Go  https://socket.dev/ MixAudit https://github.com/mirego/mixaudit NimbleTOTP Library for 2FA https://hexdocs.pm/nimbletotp/NimbleTOTP.html Microsoft Azure https://github.com/Azure Patch Package https://www.npmjs.com/package/patch-package Ruby Bundler to manage Gem dependencies https://github.com/rubygems/bundler npm-shrinkwrap https://docs.npmjs.com/cli/v10/commands/npm-shrinkwrap SemVer Semantic Versioner for NPM https://www.npmjs.com/package/semver Spec-ulation Keynote - Rich Hickey https://www.youtube.com/watch?v=oyLBGkS5ICk Amal's favorite Linter https://eslint.org/ Elixir Mint Functional HTTP Client for Elixir https://github.com/elixir-mint Tailwind Open Source CSS Framework https://tailwindcss.com/ WebauthnComponents https://hex.pm/packages/webauthn_components Special Guests: Amal Hussein and Wojtek Mach.

If you're like Robbie and you haven't dug into SQL since college, learning the basics of SQL vs NoSQL is a great place to start. Working with data isn't a part of every developer's day-to-day, but it can't hurt to understand the differences. NoSQL is gaining popularity among engineers because of the ease and flexibility of updating fields with new data. Some engineers prefer taking unstructured data and using a programming language they already know, like Python, to write their queries. SQL is far more structured and requires strict rules for writing queries. As with most things in tech, whether SQL is better than NoSQL depends on your business and use cases. In this episode, Robbie and Chuck talk about the pros and cons of SQL vs NoSQL, why they like SQL databases like Prisma and Postgres, and their Christmas and New Year festivities. Key Takeaways [00:56] - Chuck and Robbie wrap up the Advent of Whiskey. [01:35] - A whiskey Review: Yellowstone Select Kentucky Straight Bourbon Whiskey. [04:47] - SQL versus NoSQL. [ 13:24] - Using Prisma and MySQL. [28:56] - Chuck and Robbie discuss the holidays and family life. Quotes [16:40] - “I don't have to touch databases much, but when I do, I like that they are Postgres.” ~ Robbie Wagner [17:13] - “I never really remember having fun with a project that was in SQL Server or MySQL.” ~ Robbie Wagner [22:26] - “This project is using Prisma, and Prisma has nice sugar around accessing entities.” ~ Chuck Carpenter Links Yellowstone Select Kentucky Straight Bourbon Whiskey Lime Stone Branch Buffalo Trace MySQL DynamoDB PostgresSQL Prisma PostGIS Supabase Postico SQL Server Ember Data Astro SolidJS Next.js SolidStart Remix Shopify Spotify Michael Jackson Roka Akor Pepsi 90-Day Finance Andor Peaky Blinders Spirited The Greatest Showman Everyone Says I Love You Woody Allen Edward Norton Drew Barrymore Hamilton Disney Book of Mormon Deadpool Ryan Reynolds Welcome to Wrexham Mint Mobile My Next Guest Needs No Introduction Comedians in Cars Getting Coffee Kim Kardashian Kanye Titanic House of Cards James Dean Sharpie Porsche iPhone CNN Don Lemon Anderson Cooper Kevin Hart Connect with our hosts Robbie Wagner Chuck Carpenter Ship Shape Subscribe and stay in touch Apple Podcasts Spotify Google Podcasts Whiskey Web and Whatnot Top-Tier, Full-Stack Software Consultants This show is brought to you by Ship Shape.

Notes from the episode In the industry, we don't tend to own up to what went wrong in a project because it doesn't serve those involved to publicly call out struggles or failures Without this honesty on what the struggles were, what goals weren't met and why, the failures and mistakes will keep repeating themselves When choosing a system or vendor, you should look at a few and not just only look at one as it robs you of realizing all the variations and gaps out there so that you can see them in the choice you make There is a difference between CX and Digital Strategy, and many carriers invested in the latter without realizing they weren't addressing the former There's a lot of work to be done to think about how policyholders, agents or brokers, partners, etc - everyone you work with in a positive experience rather than just a digital way As we think about autonomous cars, it's hard to know what the world will exactly look like, but it will likely be a mix of Personal and Commercial exposures, with shared liability The real issue becomes if you don't even own you cars, and Uber and Lyft or whoever owns everything, and then it's all clearly a Commercial exposure Agents are still needed because even simple products exist in a context that may have complex needs Digital products are usually simpler or simplified, and that still leaves space for agents, which is sometimes for political/channel conflict reasons, but also because it is hard to buy many of these products as they are without help The rise of Low Code / No Code solutions is great, but they often sit on top of legacy systems, so there is still a lot of change needed We talked about a lot of the new and exciting things going on Usage-Based Insurance Continuous Underwriting Micro-Insurance Point of Sale Insurance or Embedded Insurance Parametric Policies Gig Economy Policies that are hybrid of Personal and Commercial Insurance works best when it covers a broad set of risks, but some of these new types of products (Micro, UBI) get much more specific, which sometimes is great, but sometimes can mess up the economics All of the startup carriers are really pushing the innovation of the industry; some will work out and be adopted by other carriers and some won't, but that will show us what does and doesn't work This episode is brought to you by Medallia (Medallia.com), and the book series, "The Future of Insurance: From Disruption to Evolution" by Bryan Falchuk (future-of-insurance.com).

2000年4月14日，在美国的威斯康星州，冬天的寒冷仍然笼罩着这个中北部的大地，在万物仍未复苏季节里，一个生命在这一天被发现永远的离开了人世。他躺在一家廉价的汽车旅馆的地板上，手里紧紧握着一个烈性酒的酒瓶，房间里稀稀拉拉的散落着几个已经喝干的酒瓶...很快，这个酒店的工作人员打电话报警，警察赶到现场，很快确认了这个人的身份和死因，他死于过量饮酒引起的急性脾出血，在此之前的十几年中，这个37岁的中年男子，因为饮酒已经多次入狱，他也多次尝试禁酒，但总是无功而返，最终，他的身体被酒精彻底摧毁，穷困潦倒的离开了这个世界。当时，北国依旧寒冷，身边没有亲人，他走的时候，不知道是否对这个世界有一丝牵挂。那一天是2000年4月14日，时至今日，几乎没有人记得他是谁，即使他留下的遗产肯定帮助了我们所有人。菲尔•卡兹在你的电脑上打开一个zip文件，然后用UltraEdit这样可以支持二进制的文本编辑器打开这个zip文件，你就可以看到这个天才的名字的缩写，PK，他的名字叫菲尔卡兹，他用这种方式，留在了我们的电脑里，留在了每一个zip压缩包里，只是，没有人知道他的存在。我猜可能会有一些同学不想动手查看二进制的zip文件，所以，我随便打开了一个zip，截了个图，放在我的微信公众号里，大家可以看到，zip文件格式的前两个字母就是PK。前两个字母是PK菲尔卡兹，1962年出生，因为他并不是传统意义上的名人，并且在37岁的时候就孤独的离开了人世，因此，他年轻时候的事迹并不为人所知。其实这符合一般规律，像我们这种默默无闻的人，根本没人在乎你小时候干了啥，在哪里读书，没人知道的。只有等出名以后，再开始重新创作一下，大部分的自传都是这么搞的，根本没什么实话，很多人都是创作自己小时候的故事。但是本文的主角，菲尔卡兹同学，他37岁去世，正如《再别康桥》那首诗里所写的：悄悄的我走了，正如我悄悄的来；我挥一挥衣袖，不带走一片云彩。他前半生的事迹并不为人所知，所以，我也不能胡编乱造，因为他这样的技术人员，我非常的佩服，即使他穷困潦倒，客死他乡，我也很佩服。正因为佩服，我觉得任何的神话他，都是对他在天之灵的不尊重。虽然把他小时候说的很聪明灵利，比如两岁背唐诗，三岁写文章，五岁抄党章会让他的一生显得很精彩，但是，这是不对的。所以，我并不知道他小时候怎么样，只能从他大学时候开始写。他大学实在威斯康星大学读的，专业是计算机工程科学，然后大学他做了啥也不清楚，反正他毕业了。毕业以后，就去了一家叫洛克威尔自动化的公司，这家公司至今仍然比较厉害，他当时所从事的工作是写软件来控制起重机的机械手臂的，一个很普通的程序员。和我们这些人一样，他也喜欢上网。但是那时候上网和现在上网，还是有巨大的不同。在当年，也就是1988年左右，上网的时候需要通过调制解调器，将电话里的模拟信号转换成数字信号来上网，速度非常慢，价格非常贵。那时候也没有现在这种一个首页就有5M的门户网站，那时候都是上BBS，类似于现在的百度贴吧吧，但是，我确信，当年的BBS是不会卖假药的！那个时候，就是登录到BBS上，然后看文章。信息以文字为主。但是，当年的网络速度非常慢，导致传送文本文件，速度也是慢的不行。因此，都必须使用压缩软件，将文件压缩以后，再互相传输，这样可以节省用户的时间。当时在美国，最流行的压缩软件叫ARC，但是，这个软件是收费的，菲尔卡兹同学觉得，这玩意也收费，受不了，他就业余时间搞了一个软件，名字叫PKARC，免费的，这个软和商业版的ARC软件完全兼容。在收钱和免费之间，广大的人民群众毫不犹豫的选择了免费软件，搞得ARC这个公司很郁闷，直接起诉了菲尔卡兹，然后，菲尔卡兹输掉了官司，法院判决菲尔卡兹今后不允许再开发PKARC这个软件，也不允许再传播这个软件。当然了，这激怒了菲尔卡兹这头雄狮。包括官司在内的这些威胁，只能吓唬一些普通人，比如说我这样的人，找几个戴金链子，纹身的大汉，上门一下，可能就可以解决问题了。实在不行，再找一些比黑社会更黑的人来解决问题，比如去派出所，实在不行，放大招，去法院起诉，这三板斧下来，99.999%的人也就服气了。但是，问题是，这个菲尔卡兹是一头狮子，这个就难办了，法院判决下来以后，他被彻底激怒了。这一怒不要紧，他喝了一瓶酒冷静了一下，花了两周时间，开发了一个软件，最后把那家公司干死了，我查了一下，有个信息说那家公司有300人左右，然后他一个人，几瓶酒，外加两周时间，那家赢了官司的ARC公司就稀里糊涂的死了。这个等会儿我们再说，先来说说压缩的问题。因为我这个节目，纯粹是自己自娱自乐，所以呢，我想讲技术就讲技术，现在我要开始讲压缩的技术。从本质上来讲，压缩的目的即使消除冗余。比如说，数据得有冗余才可以压缩，如果没有冗余，根本没办法压缩。比如说，让我们压缩20万位圆周率，这个再聪明的人也没法压缩，因为圆周率没有冗余，用啥算法也白搭，无理数没法压缩。压缩的基本原理就是寻找重复出现的字串，然后用更短的符号来代替。比如说，有2万位数字1，这个很好压缩，因为都重复么，可以用几个字符代替，比如：用字符串2万来表示，然后再加上个1。这样就可以压缩了。再比如，“然而并没有卵用”这7个字，可以用“然并卵”来代替，也算是压缩的一种，解压的过程在我们每个人的脑子里。那我们再来考虑一个问题，压缩有极限么？有没有可能无限的压缩下去呢？答案是，没有！比如很多人说自己发明了某种特别的牛逼的算法，比现在的好多少倍，这个基本上就是吹牛。比如说，在1992年，美国有一家叫WEB Technology的公司，宣称可以将任何文件压缩为原来的1/16,这个一看就是吹牛，不过这家公司就靠这个技术，忽悠了很多粉丝，还骗了不少投资，最后当然倒闭了，但是从骗投资的角度，这个技术是成功的。如果我们从纯技术的角度来看，这个撒谎一点也不高明，因为他说任何文件，他都可以压缩为原来的1/16，其实我们可以随便拿个文件，让他压缩，然后获得了一个1/16的文件，然后再递归让他压缩... 然后一个好好的文件，就压缩成0了。所以，我实在是搞不懂这个技术竟然能骗那么多钱，看来还真是没有赚钱的眼光啊！在1948年，贝尔实验室工作的香农发表了经典的论文，论文的题目叫《通信的数学原理》，这个学计算机或者通讯专业的学生肯定都是知道这一篇论文的，这篇论文的核心思想是：任何信息都存在冗余，冗余的大小与信息种每个符号出现的概率有关。然后香农借鉴了热力学的概念，把信息中排除了冗余以后的平均信息量称为信息熵，并且给出了计算信息熵的数学表达式。这篇论文就是信息论的开山之作，也正是这个信息熵奠定了所有压缩算法的基础。因此，可以根据香农老师给出的数学公式，计算出压缩的极限。讲压缩算法，必须要讲的一个算法叫LZ算法，为啥叫LZ算法呢，因为这个算法是两个犹太人的名字的首字母，一个是L，一个是Z。这个算法非常的简单，如果大家会查字典的话，就一下子明白这个LZ算法的原理了，就是使用字典的页码和行号来代替每一个单词，因此基于LZ算法的这类压缩算法又叫做Dictionary Coders。这两个老哥分别再1977年和1978年发表了两个LZ算法，分别叫LZ77和LZ78算法。这个LZ系列的算法影响非常深远，等会儿我再回过头来说这个算法。因为除了这个算法，还有一个系列的算法也特别厉害。在比较这两个算法之前，先说说那个算法。其实香农老师在那篇论文里，也提出了一个压缩算法，叫香农编码，但是这个编码技术，也不怎么样，后来麻省理工的一个教授，基于香农编码提出了一个改进的算法，就是我们教科书里说的Shannon-Fano编码，但是，这几个算法都是为了说明问题，顶多算是揭示了变长编码的一些基本的规律，如果碰到加密大量的数据，效率低下的和政府一毛一样。根本就没法将压缩算法真正的实用。因为一个东西一旦要大规模的实用化，就需要兼顾效率。否则的话，根本没人用。比如你压缩的倒是挺好，一个100M的文件压缩2小时，解压2小时，根本没人会用这玩意儿。在压缩算法上，第一个真正实用的算法叫Huffman编码，这个算法是在1952年提出的。当时Huffman在麻省理工读书，还是个学生。他不想上课，然后老师说，那行，你想上课没啥问题，但是，你得给我展示一下你不想上课的理由吧。我在上大学的时候，也经常不想上课，我给老师展示的理由是我特别能睡觉，只要是早上8点的课，我一视同仁的都不去上课，起不来。但是这个Huffman同学人家觉得老师说的对，然后他就设计了一个算法，来压缩。老师一看，我靠，好了，你不用来上课了，这门课满分。因此，这个不想上课的同学，设计的算法，一直到今天，都是压缩算法里的王牌，影响至今。在1984年，一个叫特里研究人员，这里的特里不是英格兰后卫那个特里，这个特里不会睡队友的老婆，发表了一篇论文，那篇论文的研究成果就是后来非常著名的LZW算法，如果有人不知道LZW算法的话，肯定看过GIF动画，就是现在咱们发表情包的那个GIF，虽然现在很多GIF已经不是第一版的GIF格式，但是，第一版的GIF动画，使用的算法就是LZW算法。这个算法就是我前面所提到的LZ算法。这个算法就是字典算法。讲到这里，我已经提到了两种算法，一种是字典式算法，就是LZ算法，一种是Huffman编码算法。现在我们主要使用的算法是字典式算法，比如WinZip，WinRAR，gzip等等，都是字典式算法。关于算法的事情就先讲到这里，希望大家对LZ系列算法和Huffman算法有所了解，为什么要讲这个呢，因为接下来我要开始讲本文的主人公了，就是菲尔卡兹。菲尔卡兹被ARC公司告上法庭以后，就输掉了官司，因为前文我提到的LZ78和LZW这两个神奇的算法，是有专利的。他能做的选择不多，只能选择性能最差的LZ77算法，这个算法的运行效率非常不好，否则人家也不会重新发明LZ78这个算法了。然后，菲尔卡兹天才般的将LZ77这个算法，和我前面提到的Huffman编码结合起来，创造了一个新的算法，名字就是deflate编码。因为他输掉了官司，他非常气愤，他使用这个他自己发明的新的算法，制作了一个软件，名字叫PKZIP，然后，菲尔卡兹将这个软件和以前他做的软件一样，免费的发放。这个免费的软件不仅仅是免费，无论从压缩比，压缩以及解压速度，都超过了商业软件ARC。结果，几乎所有的人都开始使用菲尔卡兹的软件，ARC这个商业公司，就此消失了。同时，菲尔卡兹还开放了所有的格式，他讨厌商业公司的做法，因此他的算法和ZIP编码格式都可以被任何人使用，而不用付给他一分钱。凭借这个无私的行为，菲尔卡兹赢得了尊重，当然，仅仅是声誉上的尊重。他尝试让用户能付给他一点钱，但是即使付给他钱，这个付费的软件和免费的软件并没有什么区别。结果可想而知，大家根本不肯付钱给他，所以，即使他做出了如此流行的软件，他个人并没有获得经济上的好处。如果他能从中获得一点钱的话，他也不会住在破旧的汽车旅馆里，喝着劣质的烈性酒，最终，结束了自己的生命。菲尔卡兹的zip已经无处不在，很长一段时间，winzip的下载量长期排在所有共享软件的第一位，高达2亿次，但是很少有人肯为此付钱。也许有人说，我天天用winrar这个软件啊，是的，在中国，这一点也不奇怪，但是不要拿中国的情况等同于全世界，比如如果在外企的话，发送的压缩格式，还是zip为主，为什么呢？因为winrar在国外一点都不流行。为什么在中国winrar如此流行呢？其实在盗版盛行的国家，winrar都特别流行，在盗版界，有个东西叫0day，就是正式版的软件发布以后，盗版在24小时之内出现，这就叫0day。发布0day的这个组织呢，和winrar有某种说不清道不明的关系，发布的破解补丁，只使用rar格式来发布。这就导致了一个很吊诡的现象，winrar这个商业软件竟然靠盗版组织来生存，zip这个开放格式的软件，竟然靠商业公司来支持。不管怎么说，zip是压缩格式毫无疑问的主流。在任何操作系统上，不需要安装任何软件，就可以解压zip格式，如果想解压rar格式，一定要先安装一个软件才行。让我们在回到2004年4月14日，那个寒冷的夜晚，穷困潦倒的菲尔卡兹，喝完最后一瓶酒，慢慢的倒在了地上。他不知道，他写出的软件已经让太多人受益，他只知道，他没有钱住一个好一点的酒店。在他弥留的那个瞬间，我不知道他是否还怀念这个世界，他付出了所有，他将他毕生的才华写出了一个伟大的软件，他却一无所获。自私是人类最根深蒂固的品德，如果世间真有轮回的话，今生他已经无牵无挂了，希望他永远都不会再转世为人了吧，这个人间对他的伤害太大了...就让人间留给卖假药的富豪，和爱占小便宜的群众吧。如果你觉得有用，欢迎打赏。

2000年4月14日，在美国的威斯康星州，冬天的寒冷仍然笼罩着这个中北部的大地，在万物仍未复苏季节里，一个生命在这一天被发现永远的离开了人世。他躺在一家廉价的汽车旅馆的地板上，手里紧紧握着一个烈性酒的酒瓶，房间里稀稀拉拉的散落着几个已经喝干的酒瓶...很快，这个酒店的工作人员打电话报警，警察赶到现场，很快确认了这个人的身份和死因，他死于过量饮酒引起的急性脾出血，在此之前的十几年中，这个37岁的中年男子，因为饮酒已经多次入狱，他也多次尝试禁酒，但总是无功而返，最终，他的身体被酒精彻底摧毁，穷困潦倒的离开了这个世界。当时，北国依旧寒冷，身边没有亲人，他走的时候，不知道是否对这个世界有一丝牵挂。那一天是2000年4月14日，时至今日，几乎没有人记得他是谁，即使他留下的遗产肯定帮助了我们所有人。菲尔•卡兹在你的电脑上打开一个zip文件，然后用UltraEdit这样可以支持二进制的文本编辑器打开这个zip文件，你就可以看到这个天才的名字的缩写，PK，他的名字叫菲尔卡兹，他用这种方式，留在了我们的电脑里，留在了每一个zip压缩包里，只是，没有人知道他的存在。我猜可能会有一些同学不想动手查看二进制的zip文件，所以，我随便打开了一个zip，截了个图，放在我的微信公众号里，大家可以看到，zip文件格式的前两个字母就是PK。前两个字母是PK菲尔卡兹，1962年出生，因为他并不是传统意义上的名人，并且在37岁的时候就孤独的离开了人世，因此，他年轻时候的事迹并不为人所知。其实这符合一般规律，像我们这种默默无闻的人，根本没人在乎你小时候干了啥，在哪里读书，没人知道的。只有等出名以后，再开始重新创作一下，大部分的自传都是这么搞的，根本没什么实话，很多人都是创作自己小时候的故事。但是本文的主角，菲尔卡兹同学，他37岁去世，正如《再别康桥》那首诗里所写的：悄悄的我走了，正如我悄悄的来；我挥一挥衣袖，不带走一片云彩。他前半生的事迹并不为人所知，所以，我也不能胡编乱造，因为他这样的技术人员，我非常的佩服，即使他穷困潦倒，客死他乡，我也很佩服。正因为佩服，我觉得任何的神话他，都是对他在天之灵的不尊重。虽然把他小时候说的很聪明灵利，比如两岁背唐诗，三岁写文章，五岁抄党章会让他的一生显得很精彩，但是，这是不对的。所以，我并不知道他小时候怎么样，只能从他大学时候开始写。他大学实在威斯康星大学读的，专业是计算机工程科学，然后大学他做了啥也不清楚，反正他毕业了。毕业以后，就去了一家叫洛克威尔自动化的公司，这家公司至今仍然比较厉害，他当时所从事的工作是写软件来控制起重机的机械手臂的，一个很普通的程序员。和我们这些人一样，他也喜欢上网。但是那时候上网和现在上网，还是有巨大的不同。在当年，也就是1988年左右，上网的时候需要通过调制解调器，将电话里的模拟信号转换成数字信号来上网，速度非常慢，价格非常贵。那时候也没有现在这种一个首页就有5M的门户网站，那时候都是上BBS，类似于现在的百度贴吧吧，但是，我确信，当年的BBS是不会卖假药的！那个时候，就是登录到BBS上，然后看文章。信息以文字为主。但是，当年的网络速度非常慢，导致传送文本文件，速度也是慢的不行。因此，都必须使用压缩软件，将文件压缩以后，再互相传输，这样可以节省用户的时间。当时在美国，最流行的压缩软件叫ARC，但是，这个软件是收费的，菲尔卡兹同学觉得，这玩意也收费，受不了，他就业余时间搞了一个软件，名字叫PKARC，免费的，这个软和商业版的ARC软件完全兼容。在收钱和免费之间，广大的人民群众毫不犹豫的选择了免费软件，搞得ARC这个公司很郁闷，直接起诉了菲尔卡兹，然后，菲尔卡兹输掉了官司，法院判决菲尔卡兹今后不允许再开发PKARC这个软件，也不允许再传播这个软件。当然了，这激怒了菲尔卡兹这头雄狮。包括官司在内的这些威胁，只能吓唬一些普通人，比如说我这样的人，找几个戴金链子，纹身的大汉，上门一下，可能就可以解决问题了。实在不行，再找一些比黑社会更黑的人来解决问题，比如去派出所，实在不行，放大招，去法院起诉，这三板斧下来，99.999%的人也就服气了。但是，问题是，这个菲尔卡兹是一头狮子，这个就难办了，法院判决下来以后，他被彻底激怒了。这一怒不要紧，他喝了一瓶酒冷静了一下，花了两周时间，开发了一个软件，最后把那家公司干死了，我查了一下，有个信息说那家公司有300人左右，然后他一个人，几瓶酒，外加两周时间，那家赢了官司的ARC公司就稀里糊涂的死了。这个等会儿我们再说，先来说说压缩的问题。因为我这个节目，纯粹是自己自娱自乐，所以呢，我想讲技术就讲技术，现在我要开始讲压缩的技术。从本质上来讲，压缩的目的即使消除冗余。比如说，数据得有冗余才可以压缩，如果没有冗余，根本没办法压缩。比如说，让我们压缩20万位圆周率，这个再聪明的人也没法压缩，因为圆周率没有冗余，用啥算法也白搭，无理数没法压缩。压缩的基本原理就是寻找重复出现的字串，然后用更短的符号来代替。比如说，有2万位数字1，这个很好压缩，因为都重复么，可以用几个字符代替，比如：用字符串2万来表示，然后再加上个1。这样就可以压缩了。再比如，“然而并没有卵用”这7个字，可以用“然并卵”来代替，也算是压缩的一种，解压的过程在我们每个人的脑子里。那我们再来考虑一个问题，压缩有极限么？有没有可能无限的压缩下去呢？答案是，没有！比如很多人说自己发明了某种特别的牛逼的算法，比现在的好多少倍，这个基本上就是吹牛。比如说，在1992年，美国有一家叫WEB Technology的公司，宣称可以将任何文件压缩为原来的1/16,这个一看就是吹牛，不过这家公司就靠这个技术，忽悠了很多粉丝，还骗了不少投资，最后当然倒闭了，但是从骗投资的角度，这个技术是成功的。如果我们从纯技术的角度来看，这个撒谎一点也不高明，因为他说任何文件，他都可以压缩为原来的1/16，其实我们可以随便拿个文件，让他压缩，然后获得了一个1/16的文件，然后再递归让他压缩... 然后一个好好的文件，就压缩成0了。所以，我实在是搞不懂这个技术竟然能骗那么多钱，看来还真是没有赚钱的眼光啊！在1948年，贝尔实验室工作的香农发表了经典的论文，论文的题目叫《通信的数学原理》，这个学计算机或者通讯专业的学生肯定都是知道这一篇论文的，这篇论文的核心思想是：任何信息都存在冗余，冗余的大小与信息种每个符号出现的概率有关。然后香农借鉴了热力学的概念，把信息中排除了冗余以后的平均信息量称为信息熵，并且给出了计算信息熵的数学表达式。这篇论文就是信息论的开山之作，也正是这个信息熵奠定了所有压缩算法的基础。因此，可以根据香农老师给出的数学公式，计算出压缩的极限。讲压缩算法，必须要讲的一个算法叫LZ算法，为啥叫LZ算法呢，因为这个算法是两个犹太人的名字的首字母，一个是L，一个是Z。这个算法非常的简单，如果大家会查字典的话，就一下子明白这个LZ算法的原理了，就是使用字典的页码和行号来代替每一个单词，因此基于LZ算法的这类压缩算法又叫做Dictionary

Coders。这两个老哥分别再1977年和1978年发表了两个LZ算法，分别叫LZ77和LZ78算法。这个LZ系列的算法影响非常深远，等会儿我再回过头来说这个算法。因为除了这个算法，还有一个系列的算法也特别厉害。在比较这两个算法之前，先说说那个算法。其实香农老师在那篇论文里，也提出了一个压缩算法，叫香农编码，但是这个编码技术，也不怎么样，后来麻省理工的一个教授，基于香农编码提出了一个改进的算法，就是我们教科书里说的Shannon-Fano编码，但是，这几个算法都是为了说明问题，顶多算是揭示了变长编码的一些基本的规律，如果碰到加密大量的数据，效率低下的和政府一毛一样。根本就没法将压缩算法真正的实用。因为一个东西一旦要大规模的实用化，就需要兼顾效率。否则的话，根本没人用。比如你压缩的倒是挺好，一个100M的文件压缩2小时，解压2小时，根本没人会用这玩意儿。在压缩算法上，第一个真正实用的算法叫Huffman编码，这个算法是在1952年提出的。当时Huffman在麻省理工读书，还是个学生。他不想上课，然后老师说，那行，你想上课没啥问题，但是，你得给我展示一下你不想上课的理由吧。我在上大学的时候，也经常不想上课，我给老师展示的理由是我特别能睡觉，只要是早上8点的课，我一视同仁的都不去上课，起不来。但是这个Huffman同学人家觉得老师说的对，然后他就设计了一个算法，来压缩。老师一看，我靠，好了，你不用来上课了，这门课满分。因此，这个不想上课的同学，设计的算法，一直到今天，都是压缩算法里的王牌，影响至今。在1984年，一个叫特里研究人员，这里的特里不是英格兰后卫那个特里，这个特里不会睡队友的老婆，发表了一篇论文，那篇论文的研究成果就是后来非常著名的LZW算法，如果有人不知道LZW算法的话，肯定看过GIF动画，就是现在咱们发表情包的那个GIF，虽然现在很多GIF已经不是第一版的GIF格式，但是，第一版的GIF动画，使用的算法就是LZW算法。这个算法就是我前面所提到的LZ算法。这个算法就是字典算法。讲到这里，我已经提到了两种算法，一种是字典式算法，就是LZ算法，一种是Huffman编码算法。现在我们主要使用的算法是字典式算法，比如WinZip，WinRAR，gzip等等，都是字典式算法。关于算法的事情就先讲到这里，希望大家对LZ系列算法和Huffman算法有所了解，为什么要讲这个呢，因为接下来我要开始讲本文的主人公了，就是菲尔卡兹。菲尔卡兹被ARC公司告上法庭以后，就输掉了官司，因为前文我提到的LZ78和LZW这两个神奇的算法，是有专利的。他能做的选择不多，只能选择性能最差的LZ77算法，这个算法的运行效率非常不好，否则人家也不会重新发明LZ78这个算法了。然后，菲尔卡兹天才般的将LZ77这个算法，和我前面提到的Huffman编码结合起来，创造了一个新的算法，名字就是deflate编码。因为他输掉了官司，他非常气愤，他使用这个他自己发明的新的算法，制作了一个软件，名字叫PKZIP，然后，菲尔卡兹将这个软件和以前他做的软件一样，免费的发放。这个免费的软件不仅仅是免费，无论从压缩比，压缩以及解压速度，都超过了商业软件ARC。结果，几乎所有的人都开始使用菲尔卡兹的软件，ARC这个商业公司，就此消失了。同时，菲尔卡兹还开放了所有的格式，他讨厌商业公司的做法，因此他的算法和ZIP编码格式都可以被任何人使用，而不用付给他一分钱。凭借这个无私的行为，菲尔卡兹赢得了尊重，当然，仅仅是声誉上的尊重。他尝试让用户能付给他一点钱，但是即使付给他钱，这个付费的软件和免费的软件并没有什么区别。结果可想而知，大家根本不肯付钱给他，所以，即使他做出了如此流行的软件，他个人并没有获得经济上的好处。如果他能从中获得一点钱的话，他也不会住在破旧的汽车旅馆里，喝着劣质的烈性酒，最终，结束了自己的生命。菲尔卡兹的zip已经无处不在，很长一段时间，winzip的下载量长期排在所有共享软件的第一位，高达2亿次，但是很少有人肯为此付钱。也许有人说，我天天用winrar这个软件啊，是的，在中国，这一点也不奇怪，但是不要拿中国的情况等同于全世界，比如如果在外企的话，发送的压缩格式，还是zip为主，为什么呢？因为winrar在国外一点都不流行。为什么在中国winrar如此流行呢？其实在盗版盛行的国家，winrar都特别流行，在盗版界，有个东西叫0day，就是正式版的软件发布以后，盗版在24小时之内出现，这就叫0day。发布0day的这个组织呢，和winrar有某种说不清道不明的关系，发布的破解补丁，只使用rar格式来发布。这就导致了一个很吊诡的现象，winrar这个商业软件竟然靠盗版组织来生存，zip这个开放格式的软件，竟然靠商业公司来支持。不管怎么说，zip是压缩格式毫无疑问的主流。在任何操作系统上，不需要安装任何软件，就可以解压zip格式，如果想解压rar格式，一定要先安装一个软件才行。让我们在回到2004年4月14日，那个寒冷的夜晚，穷困潦倒的菲尔卡兹，喝完最后一瓶酒，慢慢的倒在了地上。他不知道，他写出的软件已经让太多人受益，他只知道，他没有钱住一个好一点的酒店。在他弥留的那个瞬间，我不知道他是否还怀念这个世界，他付出了所有，他将他毕生的才华写出了一个伟大的软件，他却一无所获。自私是人类最根深蒂固的品德，如果世间真有轮回的话，今生他已经无牵无挂了，希望他永远都不会再转世为人了吧，这个人间对他的伤害太大了...就让人间留给卖假药的富豪，和爱占小便宜的群众吧。如果你觉得有用，欢迎打赏。

Free eBook: Data-Informed Product Design http://www.oreilly.com/pub/cpc/1220 Designers must understand user needs to create any product. But what type of data should you look at? In her new book, Data-Informed Product Design, Pamela Pavliscak outlines a way to use data of all kinds to understand the relationship between people and technology. Generally speaking, big data is quantitative; it gives you the what, where, and when, while “thick data” provides the qualitative perspective—the how and the why. Up until now, there hasn't been much information on how to combine quantitative big data with qualitative thick data. That's where this report can help.
