New top story on Hacker News: Show HN: Wachy – A UI for eBPF-based performance debugging
Show HN: Wachy – A UI for eBPF-based performance debugging
14 by vivek-jain | 0 comments on Hacker News.
eBPF is an amazing technology that allows safely running user-supplied functions at pretty much arbitrary probe points in a kernel/user space context. Much has been written about how amazing this feature is for kernel observability. But as someone who writes user space code, what I find even more amazing is the support for tracing arbitrary user space programs, with no code changes and low overhead. However, doing in-depth analysis can get complicated and time-consuming. My goal with wachy was to make this debugging significantly easier/faster to use, by displaying traces in a TUI next to the source code and allowing for interactive drilldown analysis. If you get a chance, check out the start of the demo video since (AFAIK) it's quite unique and gives a much clearer idea than I can provide with just text.

Show HN: Zipy.ai - Like Sentry + Hotjar, but with less noise
11 by msnkarthik | 5 comments on Hacker News.
Hey HN commmunity, Karthik here! Super stoked to announce the launch of Zipy today. Launching the product that you've been so dearly working on for months is like sending your newborn to school for the first time. Excitement to nervousness, anxiety to thrill, all sorts of emotions hit you at the same time. But the entire team of Zipy is confidently looking forward to the feedback you guys have in store for the beautiful product we’ve built. In community we trust! Over the past decade, from being a Web Development Intern to a UX Designer and a Product Manager, I have seen the struggles that both Frontend Dev and Product teams face in terms of understanding user behavior and debugging customer issues. Web technologies evolved significantly, but the debugging process still remained in the stone age. With Zipy, we are trying to change this. Zipy is a product that is primarily of the developers, by the developers and for the developers, essentially built to scratch our own itch, and thus, we've carefully handcrafted various workflows specifically for engineering, product, and support teams. We have been extremely lucky to get support from a bunch of awesome early adopters and partners, who were instrumental in carving our product experience. Hope you all find Zipy very useful. Please give it a try and do share your feedback here: https://ift.tt/SCclQNr Check out our Website: https://zipy.ai Quick 15 minute Live Demo: https://ift.tt/tdRDrAo Join our Discord Server: https://ift.tt/5cIQCo7 Benefits of using Zipy: Install in a minute VueJS, React, Angular, Ember, and any javascript web app support ▶ Replay customer sessions with errors in real-time Dev tools with Stack Trace, Console Logs, and Network Request Response details Search error sessions by customer name, URL, email ID, and more. Easy Slack Integration and Alerting Special Coupon for HN Community: 'ZIPYPH1MONTH' for a FREE 1 month access to our Startup Plan. Looking forward to your feedback and support. Fix what matters, Karthik and Team Zipy.

Show HN: I made Devzat – It's like discord but in the terminal, over SSH

Run `ssh devzat.hackclub.com` to try it out! The repo is here: https://ift.tt/OJgTkqe (golang). It has markdown and emoji support, DMs, channels, and it can show images too. You can send code, and it gets syntax highlighted (you can change the theme). You can ping people like so: @user and it sends them a \a, which should play an audible sound if the terminal allows it. There's inbuilt games and rainbow names and a lot of other small things I don't remember right now. You might find the auth system interesting: it's based on a hash of ssh pubkey (bans use that and a hash of IP, so it isn't so easy to get around a ban) Also an interesting issue: bots that go around trying to brute force ssh into random IPs with common usernames. My current solution is banning if rapid successive joins are detected.

Ask HN: Neutral DNS servers?
42 by NotAWorkNick | 24 comments on Hacker News.
Hi HN - Here’s a question that I hope will generate some useful comments, suggestions and links. Background for question: I normally run an internal DNS resolver with an upstream pool of 10-15 providers. These are normally a mix of Global Anycast servers (Quad9 etc) with some OpenNIC, YandexDNS etc thrown in towards the end to cover the ‘chilling effects’ blackholes. Currently Yandex DNS is pinging a timeout (either due to black-holing or DDOS’ing depending on where I connect To/From). My question to HN is this – Given my ‘Information Wants To Be Free’ viewpoint, are there any DNS equivalents of Switzerland (WWII, Neutral to all parties) providers?

Would senior engineers be interested in working reduced hours or part time?
28 by curiousresearch | 28 comments on Hacker News.
I work for a tech company and we're trying to see if there is interest from senior engineers who want to work part time. Now that we're a remote first company, we want to know if there are engineers who are at a point in their career where they no longer want to work full time, but are still interested in working reduced hours or part time. Specifically, we're not so much looking for contractors/freelancers to work on specific projects, but for an experienced senior engineer (previously worked for different start ups, or at a larger top tech company) to join a team and essentially be a guru or advisor to the team. What are peoples thoughts on this idea? Is this type of thing something that you've seen at other companies, or would be of interest to see at a company?

New top story on Hacker News: A word used only by Postgres developers
A word used only by Postgres developers
143 by ccleve | 74 comments on Hacker News.
I came across a word in the Postgres source code that I'd never seen before: "frammish". https://ift.tt/hHYFMd2... : > Therefore, they offer both exclusive and shared lock modes (to support read/write and read-only access to a shared object). There are few other frammishes. User-level locking should be done with the full lock manager --- which depends on LWLocks to protect its shared state. It sort of makes sense in context, as a "feature" or a "flourish". It also appears on the pg_hackers mailing list: > There has been some talk of separating the power to create new users from the power of being superuser (although presumably only a superuser should be allowed to create new superusers). If the planned pg_role rewrite gets submitted before the 8.1 feature freeze, I might look at adding that frammish into it. and here, from 19 years ago: > And we get ragged on regularly for the non-SQL-standard features we've inherited from Berkeley Postgres (eg, the implicit-FROM frammish that was under discussion yesterday). No amount of googling turns up a formal definition or usage outside of the Postgres community. "frammish.org" doesn't seem to be related. Are Postgres developers starting to evolve their own dialect? Should we call an anthropologist?

Show HN: I made a privacy-first minimalist Backblaze
31 by bimbashrestha | 8 comments on Hacker News.
Creator here. I was looking for something as simple as Backblaze Personal [1] but privacy focused and open source. This is my attempt to build that. Uses PyQt6 [2] for the GUI and Pyinstaller [3] for creating the platform specific binaries. The backup engine under the hood is Restic [4]. The server code is written in Laravel [5]. All the code is on GitHub [6]. I actually really like Backblaze (even use B2 for this offering behind the scenes) so this isn't meant to throw shade their way. Just wanted a private open source alternative. Something like Bitwarden but for backups.

New top story on Hacker News: Show HN: I made a WebGL-based app that traces images using circles
Show HN: I made a WebGL-based app that traces images using circles
17 by phqb | 7 comments on Hacker News.
I was fascinated by this [0] and this video [1]. After many struggles, I finally built this app that traces images using circles similar to what these videos had shown. The most challenging part (to me) is to find a way to convert images to vector lines. I had tried Potrace, but its output is not suitable for my use case: too many small elements share the same border. Potrace's goal is to represent the original image faithfully using vector lines. But I want to trace the image edges. After searching and trying some Potrace alternatives in vain, I finally found my keyword. Surprisingly (to me), it lies at the end of the wiki page of the very topic [2]. Then I found a paper [3] that has nice pseudocode and a C implementation. I rewrote the pseudocode in Rust because I wanted to experiment with rustwasm. Honestly, I didn't care much about the math behind it. From then, I could continue to finish the app and show it to the world. This app is also my chance to learn about rustwasm and WebGL. FYI: this app is offline-only; your images never leave your browser [0] https://www.youtube.com/watch?v=r6sGWTCMz2k [1] https://www.youtube.com/watch?v=-qgreAUpPwM [2] https://ift.tt/Pro6wkp [3] https://ift.tt/qeYthsw

New top story on Hacker News: DDoS attacks slow down Citizens' Initiative signing in Finland
DDoS attacks slow down Citizens' Initiative signing in Finland
20 by ptaipale | 0 comments on Hacker News.
The recent dramatic policy shift in Russia has brought out two Citizens' Initiatives in the Finnish government's net portal. Both are about NATO membership in the country which is traditionally militarily non-aligned. First initiative (open Feb 21) proposes a NATO membership referendum, the other (open Feb 28) proposes that parliament should go ahead to membership procedures without referendum, because of expected Russian harrasment and influence on the referendum procedures. The government portal for initiatives has been very slow today. The authentication to sign any of the initiatives is done either by a person ID smartcard, or bank-based identification. Most people use the bank authentication (in most cases 2FA using mobile phone) because they don't bother with smart card readers. The first of the initiatives has already passed the threshold (50 000) which automatically brings it to the table in Parliament. The other initiative has collected 35 000 signatures in 30 hours, meaning it will also pass the threshold tomorrow, despite many people not being able to sign it due to bank connections failing under DDoS.

In the spirit of some states now requiring salary ranges for job postings I think it would be good if HN followed that trend. I often read the “Who is hiring?” posts but I have no idea if the jobs are even remotely within my range. I think it would save everybody a lot of time if a range was posted.
