Mel Robbins(就是那个 The 5 Second Rule 和 The Let Them Theory 的作者)在本视频中通过心理学和神经科学的视角,颠覆了人们对拖延症的传统认知。她首先抛出了一个核心观点:你不是一个拖延者,你只是养成了一个拖延的习惯。这一区分至关重要,因为如果是性格缺陷,可能无法改变;但如果是习惯,就可以利用科学手段去打破。
拖延症与工作本身毫无关系,它的本质是一种压力释放机制(Stress Relief)。生活中的各种压力源——无论是人际关系冲突、家庭健康问题,还是财务危机——都会在潜意识中形成巨大的压力球。当你准备工作时,大脑感知到这种压力,并对那些具有挑战性的任务(如打重要电话)产生抗拒。为了逃避这种不适感,大脑会引导你去寻求即时的解脱,比如看猫咪视频或浏览无关信息。这种逃避行为虽然带来了暂时的轻松(奖赏),但随之而来的是自责,导致压力的进一步累积。
为了打破这一恶性循环,罗宾斯引入了习惯的三个组成部分:触发器(Trigger)、行为模式(Pattern)和奖赏(Reward)。在拖延症中,触发器永远是压力。既然我们无法彻底消除生活中的压力,唯一的解决之道就是改变回应压力的“行为模式”。她提出的具体方法是:当你意识到自己在逃避时,承认自己处于压力之中,然后倒数 5-4-3-2-1。这一简单的倒数动作能打断大脑的惯性思维,唤醒负责理智决策的前额叶皮层。紧接着,强迫自己只工作 5分钟。这利用了心理学原理:拖延的问题在于“开始”这一动作的阻力,而非工作本身。研究表明,一旦你跨过了开始的门槛,80%的人都会选择继续完成任务。

这个 Topic 其实在作者 The 5 Second Rule 这本书中有提到过,这个视频又细化了下。
Robbins 强调了一个核心科学事实:恐惧和兴奋在生理状态上是完全相同的。无论是恐惧还是兴奋,身体都会经历心跳加速、出汗、皮质醇激增等“高唤醒”状态。唯一的区别在于大脑如何解释这种身体反应——是将其标记为“危险”(恐惧)还是“刺激”(兴奋)。因此,传统的建议如“冷静下来”或“积极思考”往往无效,因为要求身体从极度激动的“高唤醒状态”瞬间切换到放松的“低唤醒状态”是非常困难的,这就像试图用一块石头去拦停一辆高速行驶的火车,只会导致灾难。
为了解决这个问题,Robbins 提出了一种结合了“5秒法则”(The 5-Second Rule)和“锚定思维”(Anchor Thought)的策略。通过倒数 5-4-3-2-1,我们可以激活前额叶皮层,打断恐惧的惯性思维;紧接着,利用一个与当前情境相关的、积极的“锚定思维”来重新构建大脑的认知。这种方法并不试图消除身体的激动反应,而是顺势将其重新定义为“兴奋”。通过 Mel 自己在后台准备演讲时的亲身经历,以及她克服飞行恐惧的案例,视频生动地展示了如何利用这一技巧“欺骗”大脑,将恐惧转化为兴奋,从而夺回对行动的控制权。

顺着 The Let Them Theory,摸到了作者 Mel Robbins 的这个视频:8 Things To Tell Yourself Every Morning。在这期 Mel Robbins 的播客节目中,她分享了八句简单却极具力量的“早晨真言(Mantras)”,旨在帮助听众重新编程大脑,从默认的消极和焦虑模式转变为积极、坚韧和充满希望的状态。
视频的核心概念围绕着“网状激活系统”(Reticular Activating System, RAS)展开。Mel 用“绿色皮卡车”的例子生动地解释了 RAS 的过滤功能:如果你不告诉大脑什么是重要的(比如积极的事物),大脑就会将其过滤掉。但这八句话能充当新的指令,强迫大脑去寻找美好的一天、期待酷的事情发生,并确认自己有能力应对挑战。
这八句话涵盖了从设定当天的基调、缓解对未来的恐惧、自我同情到确认自我价值的方方面面。Mel 建议听众坚持练习 30 到 60 天,通过书写或朗读的方式,彻底重塑大脑的神经网络,让自己成为一个在任何境遇下都能保持韧性和希望的人。
-
“今天会是美好的一天。”(Today is going to be a great day) 这句话的核心不在于盲目乐观,而在于“态度的选择权”。这是在告诉大脑:“无论发生什么,我有能力决定我的态度。”
-
“今天会有很酷的事情发生在我身上。”(Something cool is going to happen for me today) 这句真言将生活变成了一场“寻宝游戏”。当大多数人醒来都在为可能发生的坏事做心理准备(Bracing for the worst)时,这句话创造了积极的期待(Anticipation)。当你期待好事发生时,你会敏锐地捕捉到那个许久未见的老友发来的短信,或者在工作中得到的一个小机会。它通过 RAS 机制,让你注意到原本可能会被忽视的小确幸。
-
“无论发生什么,我都能搞定。”(No matter what happens today, I can handle it) 这是针对焦虑症患者最有力的一句话。焦虑的本质是对不确定性的恐惧,以及对自己应对能力的怀疑。这句真言直接挑战了这一核心恐惧。它并不承诺事情会一帆风顺,而是承诺无论事情多么糟糕,你都拥有应对的韧性。这是一种深层的自我赋能,让你从对未来的恐惧中收回力量,专注于当下的应对能力。
-
“我要为我如此努力而给自己更多肯定。”(I need to give myself more credit for how hard I'm trying) 生活中的很多努力是隐形的:你为了早起做的挣扎、你即使心情不好依然礼貌回复邮件、你在崩溃边缘依然照顾好了孩子。Mel 强调,努力本身就值得被看见,即便结果尚未显现。如果你总是等待外界的表扬,你可能会等一辈子。通过这句话,你成为了自己最好的拉拉队长,这种自我认可会形成正向循环,让你更有动力坚持下去。
-
“我允许自己是一个‘正在进行时’的作品。”(I'm allowed to be a work in progress) 这句真言是完美主义的解毒剂。它给了我们犯错的空间和成长的许可。
-
“激动人心的人生新篇章从今天开始。”(An exciting new chapter in my life is starting today) 这是一个随时可以按下的“重启键”。很多人认为必须等到分手、毕业或搬家才能开始新篇章,但 Mel 提醒我们,只要你愿意,任何一个早晨都可以是新篇章的开始。
-
“只要我坚持出现,生活就会奖赏我。”(If I keep showing up, life will reward me) 这是关于耐力(Stamina)的真言。很多时候,成功只是因为“没有放弃”。Mel 将其称为“做重复的动作(Doing the reps)”。
-
“我对这个世界有重要的贡献要在这个世界做出。”(I have an important contribution to make to the world) 这是最深刻的一句。在这个拥有 80 亿人口的星球上,你是独一无二的——你的声音、你的故事、你的 DNA 无人能及。即使你觉得目前一事无成,你对他人的善意、你的微笑、你所传递的能量,都是对世界的贡献。这句话旨在唤醒你的自我价值感,消除“隐形人”的感觉。当你相信自己的存在有意义时,你会更自信地与世界互动,而这种正向的能量本身就是对周围人最好的礼物。










A more sustainable way to do business
这篇文章探讨了一种反直觉的商业与生活哲学:“缓慢成长,保持小规模”(Grow slowly, stay small)。作者深受日本传统工匠精神及百年老店的启发,推崇那种通过长期、持续的投入来打磨技艺的态度,认为这才是创造美好事物的正途。与现代社会追求快速扩张、融资上市、获取暴利的商业模式不同,作者指出这种激进的扩张往往会导致组织脆弱、资源分散以及丧失自主权。
文章引用了经典的“渔夫与商人”寓言,生动地说明了盲目追求规模往往是徒劳的——人们忙碌一生追求的“退休生活”,往往就是当下已被牺牲掉的宁静与满足。作者强调,关键在于通过界定什么是“足够”(Enough),来区分对地位的追逐与内心的满足。最后,作者以自己的项目“Bear”为例,展示了这一哲学的实践:项目能够覆盖成本、提供体面的生活质量,且因未引入杠杆而保持了完全的掌控权。这种模式不仅风险更低、压力更小,更重要的是,它赋予了作者热爱生活和持续精进技艺的空间。
1. The Context: The "Cancer Arc"
To fully appreciate this comic, you must understand the history behind it. In 2010/2011, Randall’s fiancée (now wife) was diagnosed with Stage III breast cancer. Over the years, Randall has released specific comics marking the passage of time since that terrifying diagnosis:
- "Probability" (#881): Dealing with the initial statistics of survival.
- "Two Years" (#1141): A fragile celebration of making it past the initial treatment phase.
- "Seven Years" (#1928): Moving further into remission.
"Fifteen Years" is the latest, and perhaps final, major milestone in this specific narrative arc. In oncology, reaching the 15-year mark often means a patient’s life expectancy and risk of recurrence are statistically similar to someone who never had cancer.
2. Panel-by-Panel Breakdown
The comic is structured as a montage of moments—some terrifying, some mundane—spanning the last decade and a half.
The Early Anxiety (Rows 1-2)
- The Hospital Scenes: The comic starts with flashbacks to chemotherapy and hospital beds ("Bleep... Bleep...").
- The "Next Year" Promise: We see them planning a trip to the mountains "next year." In the context of a severe diagnosis, making plans for a year in the future is an act of radical hope.
- The "Two Years" Mark: A reference to the previous comic. They are looking at a bird, simply existing.
The Middle Years: Fear and Normalcy (Rows 3-5)
- "Scanxiety": There is a panel where Randall’s wife worries that a pain in her toe is the cancer spreading. This is a very real psychological burden for survivors; every minor ache feels like a return of the disease. The doctor reassures them, but the fear is palpable.
- Life Happening: Interspersed with fear are signs of life moving forward. We see them having children (the stick figures with smaller stick figures), hiking, playing games, and dealing with everyday chaos ("Has anyone seen the hand cart?").
- "Ten Years": A quiet panel of them looking at the stars. The silence suggests a peaceful stability.
The Climax: The Aurora (Large Color Panel)
- Towards the bottom, the comic breaks its usual black-and-white format for a stunning, wide-aspect depiction of the Aurora Borealis (Northern Lights).
- Symbolism: This represents the beauty of the world they fought to stay in. It is a moment of pure awe, likely fulfilling the travel promise made in the earlier panels. It signifies that they didn't just survive; they lived.
3. The Ending: The Twist on Aging
The final row delivers the emotional punchline that defines the comic.
Wife: "I am having some weird symptoms. Joint pain, fatigue. I think I'm losing my close-up vision."
Randall: "Yeah. Me too."
Wife: "I think we're getting old."
In any other context, complaining about joint pain and bad eyesight is negative. Here, it is the ultimate victory.
Randall (Final Panel): "I guess that's okay. It's all I wanted."
The Core Theme: The comic reframes the concept of aging. We often fear getting old, but for a cancer patient and their partner, getting old is the goal. It is the privilege that was almost taken away from them. The "weird symptoms" aren't signs of cancer returning; they are the mundane, beautiful symptoms of having survived long enough to age naturally.
Summary
"Fifteen Years" is a celebration of the mundane. It acknowledges the trauma of the past 15 years—the medical scans, the panic over toe pains, the exhausting treatments—but concludes with deep gratitude for the "boring" reality of growing old together. It is widely considered one of the most touching comics Randall Munroe has ever published.


This is an in-depth guide on drawing fundamentals. Learn what they are, and how to practice them. Includes techniques, materials, exercises, resources, and much more.
本文是一篇关于绘画基础的深度指南,旨在帮助自学者更快地提升绘画技能。作者Felix分享了自己学习绘画的经验,强调了掌握绘画基础的重要性,并指出清晰的基础知识概览能有效避免学习过程中的困惑和挫折。文章将绘画基础分为线性绘画、色调绘画、形态绘画和画面构成四个主要部分,每个部分都详细阐述了关键技能、练习方法和相关概念。
在线性绘画基础部分,文章首先强调了“落笔”的重要性,认为自信而精准的笔触是优秀画作的基础,并提供了直线、曲线、S形线和线性渲染等练习。接着,详细介绍了测量技巧,包括第一步的轻柔起稿、检查角度、三角测量、垂线检查和负空间观察,以确保画作的准确性。随后,探讨了形状在设计中的关键作用,鼓励通过研究大师作品来简化和理解形状。最后,介绍了姿态绘画,强调在有限时间内捕捉主体精髓的能力,并建议通过速写练习来提升。
色调绘画基础部分,文章指出色调绘画是迈向绘画和视觉思维的重要一步,并推荐使用铅笔、炭笔等工具进行练习。重点介绍了“过手握笔法”及其在绘制大面积色调时的优势,并强调了正确削铅笔的重要性。此外,还探讨了感知明暗值的能力,建议通过眯眼观察和进行2-3值景观研究来简化视觉信息。
形态绘画基础部分,文章将形态定义为使画作具有三维感和真实感的关键,融合了线性与色调技能。它涵盖了透视、光影和边缘三个核心元素。透视部分建议学习绘制基本几何体(盒子、圆柱、球体、圆锥)的1、2、3点透视,并通过大师作品研究来内化。光影部分则强调了理解不同光照场景和明暗理论(高光、半调、核心阴影、反光、投射阴影)的重要性。边缘部分则解释了如何通过明暗差异和渐变来表现物体表面的转折。
画面构成基础部分,文章将其视为更高级但同样重要的绘画技能。首先是主题知识(解剖学),强调深入了解描绘对象(如人体解剖)能显著提升绘画能力,并提供了线性与色调解剖学研究的练习方法,以及学习经典视觉模型(如Azaro头部、Loomis模型、Reilly节奏、Hogarth模型)的建议。其次是材料选择,指出不同材料(笔、纸、炭笔、彩色铅笔等)各有特点,能带来不同的学习体验和视觉效果,鼓励艺术家进行实验。最后是构图和设计,构图关注宏观层面的线条、形状和明暗块的整体排列,以引导观众视线并最大化视觉冲击力;设计则涉及绘画过程中每一个笔触的视觉决策,包括线条的质感、形状的平衡、边缘的处理、媒介的选择以及光影的创造性运用,强调有意识的设计决策是清晰表达愿景的关键。

Raph Koster 在其文章《我如何分析游戏》中,详细阐述了他作为游戏设计师分析游戏的方法论。他强调,分析游戏不应仅仅停留在玩家的主观体验层面,而应深入挖掘其“地下”的系统和机制。他将游戏体验比作山顶,而其下的地质构造(如构造板块、火山活动)才是决定山脉形态和位置的根本,这与冰山的比喻不同,因为冰山水上水下本质相同,而游戏体验与底层系统在本质上可能大相径庭。
Koster 的分析过程分为几个核心步骤。首先,他会抛开个人经验,剥离游戏的表面体验,直达其核心机制、输入、过程、规则和代币等系统层面。他认为新的游戏机制非常罕见,大多数游戏都是对现有机制的变体和深化。在这一阶段,他会探究游戏的可能性空间、玩家选择的后果、系统是否可被利用、技能的重要性以及玩家的学习过程和心智模型的构建。他进行这种机械层面的分析,主要是为了提升自己的设计技艺。
其次,他会审视这些系统“关于什么”,即设计师试图通过这些系统实现什么目标。常见的意图包括让玩家持续游玩、付费、关注体验而非系统本身,以及让玩家感到强大。他更欣赏那些具有更深层次系统意图的游戏,例如鼓励玩家互助、质疑规则、学习新思维方式或体验利他、合作、创造力等非权力带来的愉悦。
接着,他会评估玩家与系统的互动方式,包括输入操作和反馈。这涉及“游戏手感”、响应度、奖励信号和学习支架等,但仍避免陷入游戏所提供的具体“虚构”体验。通过这些分析,他能判断游戏是否有效地实现了其预设意图。例如,他以《侠盗猎车手V》的抢劫教程为例,指出其在可用性设计上的不足。
最后,他会重新审视游戏体验本身,但此时已带着对底层系统的深刻理解。他会从视觉叙事、图形渲染、音乐、文案等非游戏特有的艺术形式角度进行评判,并将其与电影、书籍等其他媒体的艺术标准进行比较。他会探究体验的意图,并认为如果无法明确意图,则视为一种失败。他特别关注系统意图与体验意图是否匹配,指出许多游戏在这两方面存在脱节,导致“空洞的山脉”。他认为,只有当游戏在各个层面都展现出高水准的执行力,并且系统与体验的意图高度一致时,才能获得他的最高评价,例如《请出示文件》。他承认这种分析方法是高度以“技艺”为中心的,旨在评估作品如何实现创作者的意图,而非仅仅关注玩家的乐趣或文化语境。他希望这种全面的分析方式能被更广泛地采纳,以促进游戏设计领域的发展。

本文由 Thorsten Ball 撰写,旨在提供关于如何进行有效产品演示的实用建议。作者强调,成功的演示不仅仅是展示产品功能,更重要的是与观众建立连接,清晰地传达产品的价值和解决的问题。文章开篇即指出,演示者应首先明确产品解决的问题及其背后的原因,从而为观众提供一个理解产品的背景和动机。
在演示过程中,作者强调了保持流畅性和同步性的重要性。他建议演示者不要自我打断,并确保口头讲解与屏幕内容保持一致,避免观众分心。时间管理也是一个核心要素,作者反复强调要“保持简短”,甚至“更短”,以避免冗余信息和观众疲劳。
为了确保观众抓住重点,作者建议演示者主动指出关键信息,例如在展示一个处理大型文件的工具时,要明确告知观众其处理能力,而不是期望他们自行发现。同时,演示中应避免展示不必要的内容,例如全屏录制时显示无关的菜单栏图标或电池电量,这些都可能分散观众的注意力。
在视觉呈现方面,作者提供了具体的操作建议。由于演示者无法使用激光笔或手指指向屏幕,他建议通过晃动光标、进行选择或高亮文本来引导观众的视线,确保他们知道应该关注哪里。此外,技术细节如使用 1080p 分辨率和增大字体大小,都是为了提升观众的观看体验和信息接收效率。
心理学层面,作者提醒演示者避免使用“可能不会成功”之类的负面预设,因为这会引导观众关注潜在的失败而非产品的成功之处。最后,文章强调了视觉化数据的重要性,指出“图片胜过千言万语”。当产品带来显著改进时,例如日志摄入量减少 100 倍,仅仅口头说明是不够的,应该通过前后对比的仪表盘或磁盘使用情况图表来直观展示这些成果,从而增强说服力。

本文深入探讨了游戏设计的核心原则,将其提炼为十二个关键步骤,旨在帮助游戏开发者更好地理解和实践游戏设计。作者Raph Koster强调,游戏设计的本质在于“解决问题并掌握问题”,而“乐趣”则源于对预测的进步。文章首先定义了游戏中的“乐趣”并非简单的感官刺激,而是通过解决问题获得掌控感的过程,即使这个过程可能伴随着痛苦和挑战。
接着,文章区分了“问题”和“玩具”,指出玩具是具有规则但缺乏明确目标的系统,而游戏则是在玩具的基础上添加了目标。游戏的核心在于“不确定性”和“预测”,好的游戏问题应具有深度、不确定性,并能在多种情境下出现。为了保持玩家的参与度,游戏需要通过“循环”来不断提供新的挑战,包括玩家与问题互动的“操作循环”和玩家技能提升的“进程循环”。
“反馈”是玩家学习和进步的关键,它需要清晰地告知玩家行动的可用性、执行情况、对问题状态的影响以及是否有助于达成目标。为了避免玩家感到厌倦,游戏设计需要引入“变化和升级”,通过不断增加情境的复杂性来推动玩家学习和发展新的策略。
“节奏和平衡”是确保玩家体验的关键,游戏应遵循学习曲线,提供适度的挑战,并在高潮和低谷之间进行切换。文章指出,游戏往往由多个相互关联的“子游戏”组成,这些子游戏通过“价值链”和“游戏经济”形成复杂的系统。
在“实际系统设计”部分,作者强调了游戏设计中问题的多样性和可组合性,并列举了数学复杂性、理解他人思维和掌握身心等核心问题类型。这些问题可以通过“借鉴”现实世界或其他游戏来获得。
“包装和体验”则关注游戏的呈现方式,包括设定、故事、艺术等,它们共同塑造了玩家对问题的感知和学习过程。最后,“动机”解释了玩家选择不同游戏的心理因素,强调了针对特定受众设计游戏的重要性。
文章总结道,游戏设计虽然看似简单,但其每个步骤都蕴含着深厚的学问,需要设计师掌握多领域的知识。游戏设计是一个不断学习和适应的过程,设计师需要不断挑战自己的知识边界,才能创造出持续吸引玩家的优秀作品。
题主你好,先不绕圈子,开门见山说一句:你爸是个高人。这句话你先记下来。我不是在恭维,我是认真的。我…
在知乎上看到的(确切来说,是知乎推给我的)一个问题,挺不错的,可以打开下思路。
现在有很多人想当码农,他们都很努力,无论是刷题,还是加班,看上去内卷的很厉害。我看见他们这种状态,觉得自己也非学计算机不可,而且也必须很拼。我问了我爸的意见,我爸跟我说:
无论你从事什么行业,首先要对市场有概念。
你选择了一个行业,首先要去想怎么切入市场。对于计算机行业而言,市场被大公司所占据,对于个人而言,切入市场的方式就是迎合这些公司的招聘要求,这相当于从被动的角度去解决问题。
但是如果你有自己的爱好,对这个爱好能保持长期的热情,并且这个爱好也可以切入市场,这时候,你可以选择去迎合大公司,但是同样,你也可以从社会的供需关系来切入市场,从最底层来塑造一个模式,利用复利的原理来扩大这个模式。这个模式,很可能不是技术书、面试题所能衡量的,它可能并不是高科技,也不漂亮,但是你的目的是让它增长,然后再复制这个模式。
如果你的兴趣就在这里,那你就仔细思考思考这个社会的经济形势和人与人之间的利益关系,想明白之后,塑造你的产品,为别人创造价值。慢慢你会发现,你自己有一个小圈子,在这个圈子里,你了解其中的一切,你明白游戏规则,这里的一切你做主。
相反,如果你只知道学技术,刷题,即便你的技术再好,内心深处仍然会有被别人支配的恐惧感。而且,你时常会疑问,技术到底学多少,才能没有恐惧感?答案是,越学技术,很可能你会越质疑自己。因为你在一个无比复杂的圈子里,但是很难塑造自己的圈子,就是那个你自己做主的圈子”
我自己也有这个感觉,当身体开始强健起来后,会潜移默化地带来一些正面影响,坚持下去,会是个不错的对自己的投资。

当人们感到无聊时,大脑中的“默认模式网络”(Default Mode Network, DMN)会被激活,这个网络会引导我们去思考如“我的人生的意义是什么?”这类深刻的、存在主义的问题。然而,正因为这些问题会带来轻微的心理不适,我们本能地想要逃避无聊。哈佛大学的实验甚至表明,许多人宁愿选择承受痛苦的电击,也不愿安静地独处15分钟。智能手机成为了我们消除所有碎片化无聊的完美工具,但这切断了DMN的激活,使我们陷入了“意义的厄运循环”:越是逃避无聊,就越难找到人生意义,这进而加剧了当代社会抑郁症和焦虑症的爆发。演讲者呼吁我们主动拥抱无聊,将其视为一种需要练习的“技能”,并给出了具体的建议,如在通勤或锻炼时完全不使用电子设备,以及分享他自己的“数字戒断”习惯,以帮助我们重新挖掘生活的意义并变得更快乐。

这篇文章详细阐述了作者Mitchellh如何利用AI作为主要辅助工具,开发Ghostty终端的非侵入式macOS自动更新功能。他分享了一个高度迭代的过程,包括前期人工规划、AI进行UI原型设计、代码清理、文档编写和模拟测试。文章强调,尽管AI在处理明确任务和提供灵感方面表现出色,但在面对复杂bug或生成次优代码时,人工的战略性调整、深入理解、重构和严格审查至关重要。整个项目耗时约8小时,花费15.98美元,作者认为AI加速了开发,尤其是在处理繁琐的UI样式方面,并允许他在AI工作时进行多任务处理,但始终坚持人工的最终审查和主导作用。
it's important that I review a plan before it goes off and does a ton of work.
Creating a comprehensive plan interactively with an agent is a really important first-step for anything non-trivial. I usually also save it out (via the agent) to something like
spec.mdand in future sessions I can say "Consult the @spec.md and work on some task".
I'll often make these few hail mary attempts to fix a bug. If the agent can figure it out, I can study it and learn myself. If it doesn't, it costs me very little. If the agent figures it out and I don't understand it, I back it out. I'm not shipping code I don't understand. While it's failing, I'm also tabbed out searching the issue and trying to figure it out myself.
It's at this point that I know I need to step back, review what it did, and come up with my own plans. It's time to educate myself and think critically. AI is no longer the solution; it is a liability.
In my first UI session, I had the agent create some demo code so I could see the UI in action without real update checks. But update flows have a number of scenarios and up to this point I only tested the happy path.
