It's not clear to me from the article how Mantle was porting the build scripts, infrastructure config files, etc across languages. Typically these files don't cleanly translate from one framework to another. Was this considered as part of 20% of project for human engineering effort?

> Batch is just a special case of streaming

No. Designing a system that is always up and running and can process small amounts of data constantly is a completely different problem from designing a system that runs occasionally with a lot of data. For one thing, your output formats are usually different in the latter case (maybe you're creating a PDF for example). Also the high availability requirement just makes things different at the design level.

Finally, the author claims it's not hard to switch between batch and streaming. With a large volume of preexisting data, this is just not true. For example, if you make a REST API call for each document in a DB, it can take days or months to load that. If batching together documents isn't a possibility, how do you move data between stores easily? (This data movement is often required when switching between batch and streaming.)


I'm seconding this, and I have first hand experience in exactly this problem, in finance. My first boss also had the view that "batching is a special case of streaming where you stream N and streaming is also a special case of batching where the batch size is 1 and so it doesn't matter which one you implement". This was never performant enough and he was eventually asked to leave.

The key is working incrementally, not sitting idle for months and then hammering production as hard as possible trying to get all the deferred work done in exactly one batch.

Re LinkedIn as an example of an economic termite:

It's certainly true that LinkedIn is the go to for white collar professionals seeking to make their resumes visible passively to recruiters. But isn't life still easier with LinkedIn than in the before times, when recruiters would dig deep to get folks' phone numbers and then have to call each of those people individually? (I think the modern equivalent would be email addresses.)

It's true that LinkedIn makes recruiting much easier to scale to a mass market. And it's also true that it has a monopoly on that scaling for professional employees. But is it fair to call them an economic termite when it's still possible to do sourcing in an admittedly clunky and old fashioned way? Just because they have a monopoly on scaled recruiting doesn't mean that they hold all the cards the way Linde (also in the profile) would in the gas market. This is particularly borne out by the existence of Indeed or Stack Overflow as options for posting your resume for recruiting.


Maybe it is, maybe it isn't. It's not the point. Lawyers tend to puff their smokescreens, convincing people antitrust agenda is difficult. It isn't. Once you start eating a certain amount of the pie, the rules of the game change for you, and you only, because you become too strong, causing imbalance and threatening stability.

I'm sure LinkedIn's legal department employs an army of antitrust specialists frequently dealing with accusations from their competitors. That's a good thing.

There's one position you never wanna be in: When you don't have a choice, and it doesn't matter whether you're a company or an individual. Autodesk is one prime example of a long-term nasty sales behavior significantly distorting the market. Last but not least, democratic governments around the globe have been failing to enforce these laws, not to mention these are in many cases too permissive in the first place.


LinkedIn is eating both sides of the pie; 50 eur for premium, it's ridiculous and we are here because we really have no choice.


2022 Stack discontinued their job posting options as it was not viable.


I wouldn't use Stack Overflow as an example of the market not being viable. 2022 SO had a horrible reputation problem, and their main value proposition (that is, qualifying the candidates) used a metric that was completely broken and probably counterproductive in practice (but we can't know that one for sure).

Noted, will look into this thank you


Is there someone on HN who can speak to how fast gene editing technology is improving? I was a bit skeptical of the author's claim that construction of a mammoth genome would require 5000 years, but I couldn't find any information in a cursory search on what the technology improvement speed is.


Well it used to take ~infinity years as the technique didn’t exist to do it at all.

Claims like “it’ll take 5000 years” are always funny because they’re so incredibly status quo biased, without the least bit of self consciousness of how remarkable the progress has been in the last 50 years on things like this.

Humans overestimate progress in the near term and underestimate progress in the long term.


I'm not able to see the page due to a 'No Russians--Slava Ukraini' error.


Had a lot of spammers with Russian language. Implemented expanding xml-bombs, Google Captcha, hidden input fields and a couple of other things against bots.

But the block on the russian language was most effective ( and since I was dogfooding it, I didn't see the harm at the time. But it's out of scope at this very moment, yes).

Disabled it.


Can also recommend a gzip bomb (transfer encoding+content encoding, so 40GB+ easily possible). Works for most skiddies.


I'm a fairly junior engineer at a subsidiary of one of the big 4. Before that, I was at a well-known big box store working on a few different projects.

The most impactful thing I delivered at my previous company was a script that moved all of our team's data from a self-hosted db to something on company cloud that was a lot more stable. The script itself wasn't very complicated (essentially just mongodump and mongorestore), but it made a big impact on ensuring that our team's dataset search tool would continue to be accessible to regulatory compliance folks. In turn, the regulatory people could use the tool to protect the company from getting fined under CCPA, etc.

It made a pretty big impression on me that something incredibly simple like that could make as much financial impact in expectation as that script did. Now when I mentor interns and newer, more junior people, I always tell that story as an example of how high impact can be surprisingly uncomplicated.


Is Julia's Juno IDE going to be affected by this?


No, because they already transitioned to VS Code years ago.


+1 to worrying less about what other people think of you. Ironically, this caring less can actually make people like you more (because you seem more confident).


How do you stop caring? I would give nearly anything for this superpower. Even obviously completely insignificant moments that matter to no-one can stick with me for days, and some stay with me for years, bubbling up and causing anxiety or low mood out of nowhere. No amount of rational analysis or forced positive thinking seems to help.


For me it was a combination of having achieved some amount of success (physical, financial, career) and also some humbling failure.

Basically I learned I'm not so bad, and I'm not a great man either. I'm good enough. I don't hurt other people.

I like myself, and when you genuinely like yourself then other people's opinions aren't quite as important. Nearly everyone responds positively when you aren't seeking other's approval (but are still kind).

I suspect this comes with age for a lot of people. Didn't happen for me until my 30s. Losing weight and getting into shape was a huge catalyst, I highly recommend it.


You have to expect that quite a few people aren't going to like you, in any case, you just aren't compatible. After all, do you like everybody else?


I'm sure some people don't like me. But they keep it to themselves. Even if they didn't, so what? Unless I did something to hurt them, I shouldn't be upset about it.


Perhaps cognitive behavior therapy could help with your anxiety.


Great idea! Small feedback: one of the pianos listed for Minneapolis is in Concourse C at the airport. While this is, in fact, an actual piano, you have to go through security to play on it. So I'm not sure if this counts as a public piano?


Actually these are the best public pianos in my opinion - people often search for public pianos when they are traveling and travelers often enter/exit airports. Also the airport pianos are usually the best maintained.


Along those lines: this has happened exactly once in my life but man was it something, getting off a red eye at 6am and noticing a piano in the middle of the food court. Place was a ghost town except for the morning shift relieving the evening shift, a few food vendors setting up and us, the first arrival of the morning.

Guy a few feet ahead of me pauses, sits down, and unleashes a beautiful melody that stops everyone in their tracks.

There's an applause, he calmly gets up, and we all continue on our way.

Edit: I had to do some seriously creative google dorking to find it, but this was the melody: https://www.youtube.com/watch?v=RjqkkuhRt_M


My theory for why such moments are utterly magical: For a brief moment the non-place becomes a place.

That particular pianist, Paul Barton has a whole bunch of very nice renditions of various pieces, he lives in Thailand and seems to be a genuinely nice person as well based on the videos of him that I've watched. Two recommendations, the one is Bach's version of the adagio, the other the fugue part of 'Toccata and Fugue'.

Also a big Paul Barton fan! He has a nice video playing the 18th Goldberg Variation by JS Bach (my favorite one).

https://www.youtube.com/watch?v=zka65VYD318

And he is also a great painter and there is an awesome video of him painting a portrait of Josh Wright, who is a concert pianist that has lots of educational videos online.

https://www.youtube.com/watch?v=ovu-u8BTGxI

One thing I love about watching Barton is that he has the hands of a mere mortal. So you can see how he accomplishes various reaches and fingerings if you don't have gargantuan piano hands.


Still better than the closest piano to me that it found, which is very clearly in a private residence. I wonder how its database was sourced.


I think it still belongs on the site since it’s public to anyone who has passed security.


Pre 9-11 public?
