Building FlowIn, system-wide autocomplete and intent prediction.

Previously quant trading @ Point72, AI @ Amazon

[Leo Jing @leojing314]

I built FlowIn:
→ autocomplete in every app on your Mac
→ one-click replies, rewrites, and translation

English is my second language, and the gap between what I mean and what I type costs me hours every week.

Most writing tools fix what you already wrote. FlowIn works one step earlier.

Free to download at https://t.co/qKPNaZh1lJ. Would love for you to try it!

Results and findings of this paper:

Physical activity and video gaming have completely different benefits. Spending time playing video games was associated with significantly better performance in thinking skills, but it was not related to mental health scores. https://t.co/Z2F8UN3sOM

One data point in technology making everyone richer: the cost of lighting has decreased by over 1000x.

IDE is dead, code autocomplete is dead, all you need is just text autocomplete that finishes your prompt.

[宝玉 @dotey]

Gergely Orosz 观察到的几个软件行业趋势：

1. IDE 的衰亡

像 VSCode 或者 IntelliJ 这样的 IDE 的使用频率越来越低了

2. 不再追求 Token 最大化

以前很多公司内部会有 Token 消耗的排行榜，看谁用的 Token 多，越多越光荣，现在不追求这个指标了。

3. 代码审查(Code reviews)名存实亡

现在 AI 生成的代码多到没办法审查了

4. 用开源模型可以大幅节约成本

现在开源模型的能力也不输商业模型了，不仅可以节约成本，还可以避免数据安全问题。

5. 中层管理正在大幅减少

6. 工作比以前更累了
本来以为有 AI 能帮我们干活，结果有了 AI 要干更多的活

7. 招优秀的人还是很难

除非是顶尖的 AI 实验室，招优秀的工程师还是很难。

funding is pretty cool, but have you heard of revenue?

[Victor E. Nunez @victornunez]

hey Astra, how fast are you really at using a computer?

I'm using this systen-wide autocomplete to save 50% of the typing every day.

It feels like mind reading

Things like this should be a default on your computer.

I was part of Character Labs and highly recommend it to founders working toward product-market fit. Applications are closing soon!

[John Zeratsky @jazer]

Hey yall, quick announcement:

Applications are due soon for Character Labs, our startup accelerator in San Francisco! More info and application link at https://t.co/vvU4hN0s1N

The only accelerator that's 100% focused on product-market fit, it's based on sprints that we've run with 300+ teams over the past 20+ years (including those at Google, YouTube, Flatiron Health, Slack, Uber, One Medical, Gusto, Phaidra, Inductive Bio, Fathom, Orbital, House Rx, and Extend).

If you're pre-pmf and interested in working with us, please consider Character Labs — and reply/dm if you have any questions.

@xuezhao @BasisSet Lol I like it

[Loki Yan SEO @loki_yan_seo]

今天有同学问我SEO怎么学。

我市面上的SEO的课程基本上都上过，从Ahrefs, 到SemRush，到Hubspot, 到Moz，到Coursera，到Udemy.
免费的，付费的我都上过，少则花了几千刀吧。

如果你想从头走一遍的话，除非是真的热爱，不然我不推荐。

首推，肯定是按照 @aleyda 的https://t.co/2XGEQ8dLiU上的SEO Roadmap 去学习。

这个SEO 学习的Roadmap是迄今为止最完整的SEO系统性学习路径，基本上是全覆盖。

如果你学的很快，天赋异禀，可以回去看Ahrefs, SemRush, Moz, Coursera的课。

Ahrefs: https://t.co/haHsAkFjJZ
SEMRush: https://t.co/ljjIpyyvvq

Ahrefs和SEMRush的课都算比较前沿的东西。

Moz是收费给证书的，你可以自行判断。
Coursera 的课也是收费的， 我觉得0基础去学挺好的，讲的东西是有帮助的：https://t.co/92N2ZAUQFc

2026年的话 Udemy上的东西就不推荐了。很多都是小网站，Wordpress等最基础的东西，很多适合在国外的小生意去看着自己做网站这样。

I did office hours today with a startup that had three different paths to get huge. I told them to optimize for growth rate and let that decide. Maybe the winning path will be a fourth one we don't know about yet.

[Patrick Collison @patrickc]

I love agentic coding harnesses, but they shouldn't be primarily terminal-based. The terminal is great for quick and precise commands, but information density is extremely low and UI affordances are minimal. Maybe provision of TUIs is worthwhile for occasional use (when establishing a tunnel is too annoying, or something), but it feels very strange for this to be the default modality. It took a long time for dynamic language REPLs to break out of the terminal (Jupyter notebooks and similar); I hope we don't have to wait as long for the harnesses.

@Suhail NanoGPT?

[Leo Jing @leojing314]

@ShenSeanChen yahooooo!

[Leo Jing @leojing314]

@ShenSeanChen Very, very cool! Congrats man!

[Leo Jing @leojing314]

Last month, @Azure acknowledged a billing issue that overcharged us by at least $60K for GPT-5.6 usage. We were not alone: many customers using Azure-hosted GPT-5.6 models were significantly overcharged between July 9, 18:00 UTC and July 22, 18:44 UTC.

A full month later, the incorrect charges still appear on our latest bill. We have followed up every day, yet its billing team still has not corrected the wrong overcharges.

If this happened at Alibaba or Tencent, leadership would be held accountable, possibly removed. At Azure, nobody seems to care.

I’m beginning to understand why large U.S. companies often struggle to compete with startups, and why Chinese tech giants may eventually surpass their U.S. peers.

@paulg @bscholl I also feel like people work longer hours and face more pressure than decades ago.🤔

@zionlovecookies Thank you!!
