abossy··on Claude Code Unpacked : A visual guide
It's early days and we don't fully understand LLM behavior to the extent that we can assume questions like this about agent design are resolved. For instance, is an agent smarter with Claude Code's tools or `exec_command` like Codex? And does that remain true for each subsequent model release?

What others would you recommend that are comparable in quality?
abossy··on GPT-5 for Developers
I love sitting in those planning meetings, too. /s

This is exactly right. We've adapted our workflow to kick off a task and then kick off the next one and the next. Then we review the work of each as they come through. It's just CPU pipelining for human workflow.

The process is far from perfect but the throughput is very high. The limiting factor is review. I spend most of my time doing line-by-line review of AI output and asking questions about things I'm unsure of. It's a very different job from the way I historically operated, which involved tight code -> verify loops of manually written code.

abossy··on GPT-5 for Developers
At my company (Charlie Labs), we've had a tremendous amount of success with context awareness over long-running tasks with GPT-5 since getting access a few weeks ago. We ran an eval to solve 10 real Github issues so that we could measure this against Claude Code and the differences were surprisingly large. You can see our write-up here:

https://charlielabs.ai/research/gpt-5

Often, our tasks take 30-45 minutes and can handle massive context threads in Linear or Github without getting tripped up by things like changes in direction part of the way through the thread.

While 10 issues isn't crazy comprehensive, we found it to be directionally very impressive and we'll likely build upon it to better understand performance going forward.

abossy··on The Darwin Gödel Machine: AI that improves itself by rewriting its own code
We must know very different 16-year olds.
abossy··on OpenAI releases image generation in the API
The company I work for generates thousands of these each week for children's personalized storybooks to help them learn how to read. The story text is the core part of the application, but the personalized images are what make them engaging.
abossy··on 4o Image Generation
That's very interesting. I would have assumed that 4o is internally using a single seed for the entire conversation, or something analogous to that, to control randomness across image generation requests. Can you share the technical name for this reasoning process so I could look up research about it?
abossy··on When AI promises speed but delivers debugging hell
In my experience, AI isn't very good at debugging AI-generated code. If it fails to make the right insight, it loops continuously until it's completely off the rails. I'm surprised your friend hasn't fully gotten stuck with this, as it seems like a huge risk for his startup.
abossy··on Launch HN: Codebuff (YC F24) – CLI tool that writes code for you
Very interesting, thanks!

> I fine-tuned GPT-4o to turn Claude's sketch of changes into a git patch, which would add and remove lines to make the edits. I only finished generating the training data late at night, and the fine-tuning job ran as I slept

Could you say more about this? What was the entirety of your training data, exactly, and how did the sketch of changes and git patch play into that?

abossy··on ChatGPT banned from New York City public schools’ devices and networks
I wonder if the script can be flipped to both encourage the use of ChatGPT and scrutinize its output among students. I imagine that analyzing the results of ChatGPT output for something like a routine essay prompt requires a higher degree of precision and subject-matter expertise than writing the essay itself.

Could you share the process you used to write your script?

How much time do you give candidates to complete their work samples? I'm curious whether work-sample tests filter out, say, parents with young children, in which a company with a 4-6 hour technical interview might be preferred over an unbound take-home assignment (in addition to the possibility of more interviews).
abossy··on The Problem With "Warby Parker for X"
If you're returning for the same socks year after year, why not simply buy 20 years worth of socks?
abossy··on Aleksey Vayner Has Died at 29
The girl from the creepy ex-girlfriend meme actively capitalized on her stardom. It seems that the sociological phenomenon of involuntarily going viral is becoming more well-understood.
abossy··on Getting traffic for your newly launched startup
Are sign-ups intended exclusively for people listing their gear? Perhaps you can have sign-ups for people trying to rent, too, and request additional information that would help you hone the site, such as equipment sought. For example:

Email: xxx@yyy.com

Equipment Sought: <text field or drop down listing camera lenses>

This could be done under the guise that you will send them an e-mail notification when the requested equipment is posted to the site. This would help identify whether:

1. Users are camera-savvy at all or are indeed random people "stumbling" upon the site

2. Get more detailed user needs

abossy··on Instacart adds Trader Joe's
I've heard, anecdotally, that Safeway acquired the vans for their own delivery service.
abossy··on A standing desk for $22
Agreed. I do about 50%/50%. It's improved my posture tremendously.
abossy··on A standing desk for $22
Nobody I know is capable of standing for an entire workday. A drafting stool is absolutely required, and it's often the trickiest part of the configuration; for men taller than six feet, it's very difficult to find an inexpensive drafting stool that is sufficiently tall to match the height of your desk.

abossy··on Facebook acquires team behind YC alum Caffeinated Mind
Preparing well for your interview and applying directly is much more efficient. I'm sure most entrepreneurs want to salvage they're failing startups and are eager to quit for the next venture as soon as the opportunity presents itself.
abossy··on Ask HN: What's up with Silicon Valley Bank?
They don't have a pretty website because they don't need one. Most Silicon Valley startups work with them by default.

In addition to regular banking services, they provide networking events for clients and are more startup-savvy than your typical bank. My experience with them is minimal, so perhaps somebody that's worked with them more extensively can provide more depth.

abossy··on Ask HN: Who is Hiring? (May 2011)
We sponsor H1Bs.
abossy··on How I got into YC as a non-technical single founder
How does one know his or her limits without testing them? I'd much rather hire the kid that attempted 99 failed classes.
abossy··on If average salaries are 80-100k why does everyone keep getting 40-60k offers?
If you're the best programmer you know, then you're probably not in a competitive enough market to drive prices up for programmers.

In a place like Silicon Valley, it's impossible to not meet somebody that's better than you.

Either that, or I'm seriously underestimating your programming ability!

abossy··on The Boy Who Stole Half-Life 2
Agreed. I remember reading about this years and years ago, and I thought Gabe Newell said the resolution was that they flew him to the U.S. and arrested him as he de-boarded his plane.
abossy··on Poll: Tech Bubble?
"The majority of startup companies will end up losing money" is a tautology: true no matter what the inputs are.
abossy··on Quora Raises Questions
Quora uses your Facebook friends graph to determine who you'll initially follow on Quora. It's been critical to onboarding new users and showing them relevant content immediately.
abossy··on Instapaper Releases A Full API — With A Brilliant, Unique Twi$t
This is great news. However, it's unclear how the requirement to have users subscribed to Instapaper should be communicated to the users of third-party apps. Is there an easy way to subscribe new users? Does Instapaper provide any library support for this as part of its API?
abossy··on Finally: Facebook Co-Founder Opens the Curtain on Two-Year Old Asana
This is exactly how Yammer has acquired a large percentage of their customers. It's their competitive advantage, and the reason their sales force doesn't largely subsume the rest of the company. The reason it has worked for them is that they gained a lot of momentum from winning TechCrunch50, which caused companies everywhere to try the product. That's not to say they've avoided having a sales force; it's crucial to the company's success.
abossy··on Why UT Austin is second-rate at producing startup founders
The ranking has little to do with how effective the school is at producing startups.
