阿波罗11号制导计算机中指令模块和登月模块原始代码已在 GitHub 上开源

维基百科上“阿波罗11号”词条下对阿波罗 11 号的介绍如下:

阿波罗11号(英语:Apollo 11)是美国国家航空航天局的阿波罗计划中的第五次载人任务,是人类第一次登月任务,歷時8天13小時18分35秒,繞行月球30周,在月表停留21小時36分20秒。三位执行此任务的宇航员分别为指令长尼尔·阿姆斯特朗、指令舱驾驶员迈克尔·科林斯与登月舱驾驶员巴兹·奥尔德林。1969年7月20日,阿姆斯特朗与奥尔德林成为了首次踏上月球的人类,而阿波羅11號登陸月球一事更進一步成為紀錄片和廣告常見之歷史事件。

阿波罗11号的成功实现了美国总统约翰·肯尼迪在1961年5月25日的演说中声称美国会在1970年以前“把一个宇航员送到月球上并把他安全带回来”的目标。

目前阿波罗11号制导计算机 (AGC) 中指令模块 (Comanche055) 和登月模块 (Luminary099) 的原始代码已经由虚拟 AGCMIT 科学博物馆 的伙计们完成电子化并在 GitHub 上开源,项目地址:

今年 (2019 年) 是阿波罗登月成功 50 周年,在此,荒原之梦向勇于探索未知,敢于挑战高峰的科技先驱和宇航英雄们致敬!在征服宇宙的征途上,每一小步都是伟大的进步!

Track THIS: 伪装你在浏览器中的网络身份

Track THIS 是 Mozilla 和 mschf 工作室合作提供的一个工具。Track THIS 直接翻译过来就是 “追踪这个” 的意思。

我们知道,广告商会追踪 Web 浏览器用户的浏览行为,然后根据获取到的数据描绘用户画像,从而有针对性的投放广告。Track THIS 的目的就是通过打开 100 个特定类型的标签,混淆 Web 浏览器用户的浏览行为,从而隐藏用户的真实网络画像。

目前,Track THIS 提供了四种用户类型可供选择,分别是 HYPEBEAST (潮人)、FILTHY RICH (肮脏的有钱人)、DOOMSDAY (相信世界末日的人) 和 INFLUENCER (意见领袖)。如图 1:

图 1

HYPEBEAST

使用该模式将会使广告商认为你对街头服装 (streetwear), 专享鞋 (exclusive kicks) 和新潮音乐 (latest music) 感兴趣。很明显,当你在互联网上搜索最新的商品时,你就是文化的推动者 (clearly you’re a driver for culture as you scour the internet for the latest merch drop). 如图 2:

图 2

FILTHY RICH

在该模式下,除了喝酒少 (less booze) 并且拥有许多信用卡积分 (credit card points) 之外,广告商会认为你就是生活在邦德电影 (bond movie) 里的人物。你的生活里充满奢侈的品牌 (luxury brands), 豪华的轿车 (fancy cars) 和专属俱乐部 (exclusive clubs). 还有什么没有列举出来的事吗 (does anything else even matter?). 如图 3:

图 3

DOOMSDAY

在该模式下,广告商会认为你常常花时间去搜索补给品 (supplies), 评估掩体 (evaluating bunkers), 打印阴谋论 (printing out conspiracy theories), 然后用红线把它们钉在你家卧室的墙上。如图 4:

图 4

INFLUENCER

在该模式下,广告商会认为你会沉迷于 (obsess over) 护肤流程 (skincare routines), 全身疗法 (holistic remedies), 占星术 (astrology) 和冥想应用程序 (meditation apps), 然后把这些内容发布到你的 vlog 上来增加点赞和订阅。如图 5:

图 5

我没有对 Track THIS 混淆用户网络行为的效果做评估,Track THIS 的目的也不是阻止广告商投放广告。但是,在我看来,Track THIS 的确是一个保护 Web 浏览器的用户隐私,对抗无处不在的追踪的一个有趣尝试。

However, there are a few exceptions to this new policy for Microsoft account, you can read these exceptions below:

★Purchases. If you have used your Microsoft account to purchase, or to redeem or access a purchase of, a current Microsoft product or service, your Microsoft account will remain active and Microsoft will not close your account due to inactivity. Note, this does not apply to gift cards, certifications or subscription-based purchases or services.

★Subscriptions. Your Microsoft account will continue to remain active for so long as you have an active Microsoft subscription associated with your Microsoft account. Following the expiration or termination of the subscription, you must sign in to your Microsoft account at least once in a two-year period to keep your account active.

★Account Balance. Your Microsoft account will continue to remain active for so long as you have an unspent balance in your Microsoft account (e.g. from a Microsoft gift card or a credit from Microsoft). If you live in a jurisdiction where gift cards are considered “unclaimed property,” Microsoft will, pursuant to local law, escheat the unspent balance associated with your Microsoft gift card.

★Accounts Payable. Your Microsoft account will continue to remain active for so long as there is an amount owed to you by Microsoft associated with your Microsoft account (e.g. amounts due to you from Microsoft Payment Central).

★Family Accounts. If you have an inactive Microsoft account that has granted consent for an active Microsoft account belonging to a minor, Microsoft will not close your Microsoft account due to your inactivity. Your inactive Microsoft account will be kept open by Microsoft until the minor’s account (i) is deemed inactive and closed by Microsoft, (ii) is closed by you, or (iii) transitions into a standard Microsoft account when the minor reaches the requisite age of majority in their region.

★Legal Requirements or as otherwise provided by Microsoft. Notwithstanding the foregoing, Microsoft reserves the right to maintain your account status as active, or not to close an inactive account, as required by applicable law or regulation, or as otherwise provided by Microsoft to you.
