RomanPushkin··on So you want to speak at software conferences?
This year I spoke at HOPE - Hackers On Planet Earth. The topic was "Hacking ATMs: past and present". I really enjoyed it, it took a lot to prepare though. I haven't gotten any monetary benefit from it, but I would definitely do it again.

HOPE is one of the best hacker conferences, and it's somehow [subjectively] friendlier than other. Feels like home, so if you're on hacker news, I guess you wanna speak at hacker conference or contribute to 2600? ^_^

RomanPushkin··on Launch HN: Nia (YC S25) – Give better context to coding agents
Having this RAG layer was always another thing to try for me. I haven't coded it myself, and super interested if this gives a real boost while working with Claude. Curious from anyone who have already tried the service, what's your feedback? Did you feel you're getting real improvements?
RomanPushkin··on Russia Bans Roblox
> In the West there is nothing close to that.

Well, actually, the whole cancel culture dynamic is a softer alternative to what you just described. And it doesn’t even require you to be the actor — it can be your spouse, your child, whoever. One tweet and you can lose your job, your house, your marriage, especially in an economy like this it hits hard. It really is the same idea: "your whole life, and often your family’s life, can be destroyed in an instant." You won’t go to jail, but your life can still become miserable.

Of course, the big difference is jail time — and that matters. I'm familiar with cases where a 30-year-old woman was sentenced to more than 10 years just for donating $20 to Ukrainian forces (she was traveling to her mom's funeral and got caught).

And at the end of the day, all of this is politics. If you're smart enough and in Russia or China, you can learn to navigate it. But there's never a guarantee. You can still end up as "лёд под ногами майора" ("ice under the major's feet"), as the famous Russian punk rock singer put it.

RomanPushkin··on Russia Bans Roblox
It's both good and bad. On one hand, it's sad that there's no access. On the other hand, it increases the diversity of tools and services worldwide. Google, for example, is well known for buying startups just to kill them.

In Russia and China, they have their own search engines, social networks, eBay/Amazon alternatives, and so on. These companies have produced great free software like LLMs, databases, development tools, etc.

Seeing a corporation lose control over the Internet is usually good news for us, the small people - even if that change is coming from the government.

RomanPushkin··on Mistral 3 family of models released
Mistral presented DeepSeek 3.2
RomanPushkin··on X210Ai is a new motherboard to upgrade ThinkPad X201/200
I'm the owner of one of these laptops. I paid like $2-3k or even more for the laptop. The screen got broken almost on arrival. I think few days later it started glitching. It was intermittent, so I thought it would go away. I didn't. Over time it started glitching more and more. I reached out to the person in China who sold the laptop. In broken English he told me that I should replace the screen and sent me a link. I bought the screen, actually two of them, since for some reason you can't buy one. Turned out that the screen doesn't fit, and I cracked the first one while trying to install. So now I have a laptop without a screen, and it just doesn't work.

I bought Macbook Air for $1k just one week ago. I can't be more happier. Fuck these ThinkPads.

RomanPushkin··on Search tool that only returns content created before ChatGPT's public release
For that purpose I do not update my book on LeanPub about Ruby. I just know one day people gonna read it more, because human-written content would be gold.
RomanPushkin··on Americans no longer see four-year college degrees as worth the cost
Don't forget it's free in some countries. My degree was 100% free. And don't tell me it wasn't. There has been a lot of free stuff in post-Soviet era. In Soviet Union people had more than most of the folks who are pretty much jobless and desperate now at the moment. My family gotten free 3br apartments from government. My mom and dad were high school teachers.
RomanPushkin··on The Anatomy of the Least Squares Method, Part Two
Dang, it's $10/month one... Is it worth the money?
RomanPushkin··on Ask HN: I underestimated how lonely building solo can be
I'm also building solo, applied to YC winter batch as solo, and I've been building solo for quite a while now.

My solo projects were on HN news multiple times getting hundreds and even 1000+ points (submitted by other folks tho). I am still building.

I didn't realize there is so many folks from HN building solo, so I literally 2 mins ago created a discord for all of us so we won't get lost after this post goes down: https://discord.gg/GaCz3qMK

RomanPushkin··on Cerebras Code now supports GLM 4.6 at 1000 tokens/sec
PSA: they're sold out ("GLM4.6 Temporarily Sold Out") as of 11/8/2025 for both $50 and $200 plan
RomanPushkin··on What's New in C# 14: Null-Conditional Assignments
Nice feature! (we had in Ruby for many years)
RomanPushkin··on macOS Tahoe
Maybe it's new and controversial, but I like it. Honestly, I think there is something more about it. Like another Apple product that we're going to see in the future, like Apple glasses would work perfectly with this UI.
RomanPushkin··on Many hard LeetCode problems are easy constraint problems
- Constraint solvers? That's a nice concept, I heard about this once. However, for the purposes of the interview, let's just write some Python code, I wanna see your way of thinking...

(I think it's almost impossible to convince your interviewer into constraint solvers, while the concept itself is great)

RomanPushkin··on AirPods live translation blocked for EU users with EU Apple accounts
I wish technology is not blocked that easily. I doubt people want this feature to be banned. Apple's live translation is probably the greatest feature of the last 30 years. I wanted it so bad, I lived in India and South-East Asia for 3 years, it would definitely make my experience SO much better.
RomanPushkin··on iPhone Air
Pretty excited about this one. The amount of tech went into this is obviously insane. Happy to see the company is still the driver of innovation. I bet we'll see more slim phones coming up next months from other vendors.
RomanPushkin··on OpenWrt: A Linux OS targeting embedded devices
Big fan of it. Allows you to create experimental software for OpenWrt, like I did: https://github.com/ro31337/big-internet-button?tab=readme-ov...

> In our hyper-connected world, we've become slaves to the endless scroll. Social media, news, videos - the algorithm-driven content feeds are designed to capture and hold our attention indefinitely. We tell ourselves "just 5 more minutes" but hours disappear. Our brains are being rewired for constant stimulation, making us less capable of deep thought, genuine connection, and meaningful work.

> The Big Internet Button breaks this cycle by introducing friction back into your internet consumption.

RomanPushkin··on Nepal moves to block Facebook, X, YouTube and others
> Yet it is wrong for a government to deny the people to access foreign services over the Internet when they want

"Services" here can be replaced with "control". I'm not super conservative, but social media sometimes do take control over our kids, and ourselves. If they could have offered a better way to content moderation, or ability to tune algorithms, that would be a great thing.

I recently created YouTube algo booster (open source) that allows to take this control back a little bit: https://github.com/ro31337/youtube-algo-booster

I wish there is a law that allows parents, and individuals to have control over some social media and their algorithms. For now all they do is just prevent themselves from scraping and automation

RomanPushkin··on A staff engineer's journey with Claude Code
It's easy: Cursor are resellers, they optimize your token usage, so they can make a profit. Claude is the final point, and they offer tokens for the cheapest price possible.
RomanPushkin··on A staff engineer's journey with Claude Code
There is one thing I would highly recommend to anyone using Claude or any other agents: logging. I can't emphasize it more, if you have logging you can take the whole log file, dump it into AI, outline the problem and likely you're getting solution or would advance to the next step. Logging is everything.
RomanPushkin··on Show HN: I built an app to block Shorts and Reels
Is there anything similar to block/unblock them on network level? Some kind of lists, how reliable those lists are and how often do you need to update those? Curious if I can just have a shell script and will autoupdate everything on my router - install and forget solution.
RomanPushkin··on ATM Hacking: Past and Present (HOPE conference next week)
I will be presenting my talk about ATM Hacking next week in New York. I think it would be a nice one for any hacker. If you haven't heard about HOPE, it's a good opportunity to buy tickets. They have free workshops most of the time, and they're not focused on charging you tons of cash, unlike other conferences.
RomanPushkin··on SUSE Donates USD 11,500 to the Perl and Raku Foundation
I once donated $300 to the language I like (Crystal), it was like 2-3% of my monthly salary before tax and expenses. Not bragging, and $11,5k is good money, but the donation is similar to my $5 contribution, maybe even smaller.
RomanPushkin··on Psilocybin decreases depression and anxiety in cancer patients (2016)
Thanks! I just realized we're mostly feeling normal, maybe even a bit more happy than average non-cancer family. It's only the side effects that are uncomfortable: losing money, a couple of jobs down the road, affected childhood of our 11 y.o., dealing with jerks, etc. Mood-wise psilocybin brought us back to normal life, maybe even slightly better than it was before :)
RomanPushkin··on Psilocybin decreases depression and anxiety in cancer patients (2016)
Hello from cancer family.

It indeed decreases. When my spouse was diagnosed, they prescribed her anti-depressants. We replaced them with psilocybin. Never taken any anti-depressants.

We had a very serious case with multiple surgeries, chemos, radiations. Not one, not two, and not ten or even twenty. MORE than that.

The treatment still goes on, soon it is gonna be 5 years. With ZERO anti-depressants. And I've learnt how to grow them, not buying them.

So we don't need studies, we tested it the hard way, and it works :) I can talk about it for hours.

RomanPushkin··on Finding a 27-year-old easter egg in the Power Mac G3 ROM
It's kinda cool and shows that there are real people behind corporations. Some folks with lots of $$$ say "I build this" (Zuck often says that), stealing the credit of accomplishment from small little people. While real small little people leave the note in history - "nope, it's us who put our souls into making this happen". Of course, Steve Jobs would ban this.
RomanPushkin··on Eleven v3
Congrats on v3! I have to admit Russian is pretty bad. Why even adding it to dropdown when the quality is not digestable? Curious to hear about other languages from native speakers.
RomanPushkin··on By default, Signal doesn't recall
Second this. What's the point of this security aspect when everyone has their pocket cameras in their phones? This is nonsense.

The same is true for spyware installed on employee computers. Google laptops will snitch on you if you even attempt to attach USB drive. While there is HDMI and KVMs, there is no point of having these restrictions.

RomanPushkin··on I'm Peter Roberts, immigration attorney, who does work for YC and startups. AMA
Can you clarify the current status of the U4U program? Is it limited to TPS only, or are there other pathways available? Also, what do you think the government’s broader intentions are with U4U?
RomanPushkin··on Show HN: Undetectag, track stolen items with AirTag
Tile already has this feature. You need to pass verification to use it, but it stays undetectable. However, if you got caught stalking somebody you have to pay $1M fine.
