wkoszek··on Ask HN: Cheapest/easiest way to host a static site?
Love to see projects like this still in existence. I sometimes wonder if I would get some users who could also share a box and keep it going for 30 years.
wkoszek··on Ask HN: Who is hiring? (February 2021)
Segmed | Software engineering / Product | Menlo Park, CA | REMOTE | Internships / Full-time employment / Contracts | Unlimited vacation | https://www.Segmed.ai

We provide high quality data for medical research. Think of us as Bloomberg for Medicine (or Quandl/Quantconnect for medicine). We ingest and analyze huge amounts of medical data (right now: focusing on radiology), structure it in a database and allow researchers from around the world to safely access it.

We are a startup of 4 cofounders, including ex-Apple/Google/Ericsson/Xilinx/Facebook/Salesforce people with a Stanford radiology expert in the cofounding team. We came out of the Stanford Ignite program, and were in the YC Winter 2020 batch. We're backed by Blumberg Capital, Y Combinator, nina.capital, Alchemist Accelerator, and several prominent angels from the medical industry.

Our core product is a Segmed Insight web platform for dataset building, along with our CLI product for data ingesting.

The current team size: 12

*Open roles*:

- Full-stack engineer, data pipeline (Golang/Postgres/AWS) -- You will join our team and get an opportunity to work on refactoring / improving / scaling our ETL pipeline, where millions of DICOM files need to be unified, organized in the cloud, and exposed in a safe way to the research community. We have a prototype of a search engine running on top of it, and there's a huge opportunity to learn more about scalability here.

- Full-stack engineer, web platform (Golang/PostgreSQL/Javascript) -- You will be taking a feature request from our users/customers and developing it from A to Z, and shipping it to our backend/web platform. We have an early version of our webapp up and running, and you'll be responsible for making it fast and usable. The team has a pretty good usability sense and we're working with a great UX/UI expert. We use React.JS for the exiting frontend.

- Sales person: you will spend time lining up more data partners (hospitals/medical imaging clinics) and customers (AI companies). You will help with outreach, taking introductory calls, pitching our products and interacting with customers on a daily basis.

wkoszek··on Ask HN: What does mastery look like in software engineering?
Ability to: Start small with a shitty demo which can get buy-in from other folks on a team and continue pounding out high-impact features in no time first, to sell the invention to anyone. Then get this demo cleaned up to the point it ships with docs, tests, telemetry in production, and there are no bugs and crashes. Just couple of improvement requests. And when this thing can be enabled/disabled dynamically, and enhanced/expanded for the future without major rewrites.
wkoszek··on Why Jira Sucks
JIRA is just fine. Can't really go bad with it. If you have limited needs, you can try GitHub or GitLab Issues. But for a team which may end up growing, JIRA will work. It has good integration with GitHub/GitLab, and with Smart Commits enabled, most of workflows can be baked into it. It's slow, but judging by this thread, I suspect Atlassian customers are complaining about it too, so hopefully it'll be heard.
wkoszek··on Why Jira Sucks
If you want a normal software engineering process, where you want to check in with your colleagues after 1-2 weeks on the progress etc. it's not going to happen. The normal concepts of sw. eng. aren't in Monday. It's more like a clunky to-do for non-techy people. Simple things are extremely hard in Monday. For example seeing all the tasks from all projects assigned to you -> hard. I'd rather stick with GitHub/JIRA
wkoszek··on Ask HN: Who is hiring? (October 2020)

- DevOps engineer (AWS/Ansible/Terraform) -- possible contract -- You will build us an infrastructure-as-a-code system. We need fully-automated deployment with a dev/prod environment based on VPCs, with all possible security features enabled (ElasticSearch / CloudWatch) and wire it to GitLab, so that we can start treating it as a devops dashboard. Our tech stack: Golang, Python, PostgreSQL, AWS, Ansible, Terraform, GitLab.

wkoszek··on GitHub Super Linter: one linter to rule them all
GitHub got a lot of fire in their ... after acquisition. I was stunned how fast GitLab overtook GitHub feature-wise, but looks like now they're at least trying to compete.
wkoszek··on Nasty macOS flaw is bricking MacBooks: Don't install this update
Eh. I'm so happy to now be alone. I really hope they'll hear it. I just sent my brand new MBP 16" back to Apple, because I believe that's what happened to me too. 2 weeks ago Friday an update fetched overnight messed me up--upon starting I got an installer with "27 minutes to go", then a login screen, and upon a login with my password, I got a pure-white-screen for 2-5s, then 2s of max-fan speed, and an instant reboot.

And it went on to happen in the loop: login -> white screen -> reboot.

Recovery mode + macOS reinstall = "Can't install macOS on this computer"

To my that starts to match the definition of "bricked" already, because a normal person really can't probably recover from this at that point.

Recovery mode (booted via USB drive) = "Installer is missing assets" (tried 2 USB drives, after re-downloading Catalina installer

Recovery mode (booted via USB drive with Mojave) = this is not supported anymore

Recovery mode -> Disk Utility -> First Aid -> run a FS check, turned out APFS volume is corrupted ("fsroot tree is invalid")...

Target mode (went to BestBuy to get a special "SS+" certified USB-C cable, because of course a normal cable doesn't work) connected to my macOS Catalina Mac mini -> couldn't unencrypted the APFS partition enough though the password was correct. Read every possible target mode tutorial, and there's no mention about what Catalina did to Recovery Keys/User (other than them simply not being there), but you need to pass a UUID of a recovery used, and I only had some iCloud Recovery Keys there. Tried my MacBook password, my iCloud password etc. Nothing worked. Basically I couldn't un-encrypt the drive.

Ended up just starting Recovery Mode again, mounting a separate USB disk from the Terminal, copied valuable stuff over.

Removed all APFS volumes, tried to re-install on a fresh volumes. Nothing worked. Was getting the same issues from the installer. Gave up. Packed this $4k computer and sent it back to Apple. Writing this from my Mac mini, with Catalina, happily rejecting any updates. BTW, Catalina installer is a joke. It is broken since Catalina came out, and it's not getting any better.

wkoszek··on Ask HN: What were your favorite MS-DOS productivity programs?
You mean MS Xenix aka UNIX variant, or was there some CLI tool with the same name?
wkoszek··on Ask HN: What were your favorite MS-DOS productivity programs?
Can you link which firm/company/product Tornado is?
wkoszek··on Apple Mac Pro Available to Buy
I'm going to be an honest one here: I'd love to be able to just max it all out, checkout, and have it no impact on my finances :)
wkoszek··on Stripe CLI
If you guys could make your docs available for offline/downloadable reading in apps like Dash, it'd be amazing. There's a fundraiser to do it:

https://github.com/Kapeli/Dash-User-Contributions/issues/201...

but this project would be much easier to do by someone inside of Stripe.

wkoszek··on Ask HN: One-person SaaS apps that are profitable?
Hi Nate. I've looked at Draft when I wanted to build something similar. Is it profitable to the point where you could do it full-time?
wkoszek··on Sr.ht, the hacker's forge, now open for public alpha
Congratulations from an early tester. I'm happy you're making such a good progress on this.

Also happy to see more aliens here appreciating brutalist aesthetics :-)

wkoszek··on Apple Supplier List – Top 200 [pdf]
And short-sell the ones which are likely going to get killed after Apple ASIC team brings their IP into the A-... family of chips.
wkoszek··on Ask HN: What are the most enjoyable REST APIs you've used?
I'm wondering whether what you showed here is REST. I maybe meets some indempotent guidelines, but it should be something more standard like:

``` /pages/ POST create a page /pages/{id} PUT update a page /pages/{id} GET get a page ```

as looking at some standard JS code, if you stick to this theme, you will some functionality for free, like getting an array of items after GET is done for you etc.

wkoszek··on Ask HN: What are the most enjoyable REST APIs you've used?
Have you worked with any ones you liked?
wkoszek··on Ask HN: How to start a startup that requires a high amount of initial capital?
The high-entry barrier business is where VC actually makes sense. Building a webapp and getting $3M VC money is a little bit of a waste. Building a rocket or a jet requires $100M and there's no other way around it. You're maybe somewhere in between. Or start small. Maybe in a different country/province, if you can.
wkoszek··on Commons Clause
It'd be much better if they asked people who understand business of open source on how to drive more $.

For example: it could as well be: "If you're any of: FB, APPL, MS, .... and you use this software in your cloud, you owe us $2M/yr"

It'd be much easier to analyze the impact.

wkoszek··on Commons Clause
That's the thing--it's just a copyright headache. If Amazon wants, they'll use Redis anyway.
wkoszek··on Commons Clause
Weird. Company full of Open Source guys, but I think they didn't get the right advice on a business model. The reason why MIT/BSD/Apache licenses are there is that there's a group of people who want to let companies use their stuff. If you want people pay you, you just release commercial software, without showing the source. License is something that once put in, it's too late to change later, and not disrupt how your technology is used in the field.

e.g.: I was contributing to FreeBSD because I wanted to contribute to BSD licensed-software, with a hope people from FANG would use it, and maybe hire me later. If FreeBSD made a chance to the license, it'd no longer be FreeBSD. It'd be FreeCommonsClause--different project. I wouldn't like to contribute to this.

As a CEO fo a software company, if I were to go and analyze what this license change means to my business, and probably get uncertain answer, I'd rather fork Redis from before the license change, and run on the copy.

Why? Because the fee for a US software engineer is $X, for a over-sees is $0.3X or $0.5X. Fee for a US copyright lawyer with expertise in software is 10$X. Pay that much money for no value-added to my business makes no sense to me.

wkoszek··on Startup School Advisor Track: You Are In
Yup. That's what I believed too.
wkoszek··on Startup School Advisor Track: You Are In
Haha. Exactly.
wkoszek··on Startup School Advisor Track: You Are In
Also trying to understand this, because it's unclear how "audit path" differs from: "not applied, will just watch stuff on YouTube"
wkoszek··on Startup School Advisor Track: You Are In
It doesn't help it came from "noreply" email, so it's hard to clarify anything.
wkoszek··on Startup School Advisor Track: You Are In
It's like two visa lotteries I applied two: I wasn't selected in either of them, but I knew people who were, and then this happened: https://www.reuters.com/article/us-usa-visa-mistake-idUSTRE7...
wkoszek··on Startup School Advisor Track: You Are In
I'm here because of the same reason -- looks like I'm not alone. I've had a YC advisor for about 1.5 hours, shared good news with people around, and now I'm going to tell everyone it was a fake news. How many people received this email? IMO all the people who got the 1st acceptance e-mail should get in. If not now, then in the next cohort.
wkoszek··on In a world of digital nomads, we will all be made homeless
Personally I think it's a terrible idea to work at Google, live at Google, have your Google-only relationships, have your Google kids to talk to only Google kids, and stay on the campus all the time. It's a little awkward to know I walk around the SV streets and there are people who think otherwise.
wkoszek··on Sidepact: start a company with a full-time job
Make it be $300/month. This would align people too. Or maybe publish the list of VCs and angels who will come to pitch week. If its Andressen Horowitz or Sequoia or Mayfield, that makes sense
