First, congrats on getting healthy!

Secondly, since you're presenting this as a portfolio entry, I have some open, honest feedback. I quickly reviewed the repository and there are some pretty major orange-red flags that would dissuade employers from reaching out. Some of them include:

- Lack of coherent repository structure. All files under src/ with no sense of modularity

- The commit messages are very poor. Messages like "cool" and "jump jump" and "perf" do not provide any context to anyone outside of yourself (and probably not even you will remember what those changes were days/weeks from now)

- There are magic numbers everywhere. The biggest offender I found was in shaders.ts

There are more but those are the top ones I saw from my quick review. Again this isn't meant to discourage you. I wanted to provide the feedback to help you be more successful with potential employers. Cheers!

Kafka, unlike Mongo DB, relies on recovery/replication instead of fsync:

Kafka has never tried to hide that fact and it does not, in any way, make Kafka unsafe.

This ^^^ My answer to this question would have been a VERY weak "Yes" before the Twitter disaster. Now that we're seeing the true Elon alongside real engineer feedback, it's a HARD no.

New comment by haggy in "A database without dynamic memory allocation"

That totally makes sense. I think you'd have a miserable time supporting this at scale if a re-compile is needed every time a new workload requires a tweaked setting or two. Config based static allocation is the best of both worlds.

I disagree in this case. Normally I'd fully agree with you but I think this animation style works really well given their use-case.

This is not really surprising considering that it's basically a (very cool) marketing article for their equipment.

They explain pretty clearly that this is static memory allocation. In other words, a calculated amount of (mostly) contiguous memory is allocated at startup and used very carefully, relying on disk to supply the dynamic nature of database load semantics.

Per the article: "(Currently it’s determined even before startup, at compile-time, but startup is the important point since that is the first time that memory can be allocated.)"

Sooo are we sure you can even change this via proc restart? This is saying the limits are built-in during compile...

Not a fan of what feels like an advertisement hijacking the OPs post. Most would probably prefer you just make a separate HN post.

Ah thank you. I figured the 'Q' stood for quantum but you saved me a fair amount of googling :)

The article body and headline are (of course) at odds IMO. The headline is very much "doomscroll" material while the article points out that interference could basically manifest as having to rely on secondary systems and protocols to land. If I'm missing something then happy to be corrected :D

Depends how you group them. If we're talking battle tested then yea maybe four but I believe there are many more that don't have widespread adoption

New comment by haggy in "Super Mario 64 game sells for record-breaking $1.5M at auction"

haggy — Mon, 12 Jul 2021 16:03:35 +0000

> A high rating is not enough to guarantee a high auction price - although it helps. Another copy of Super Mario 64 in the same auction with a 9.6 A++ rating sold for a comparatively affordable $13,200

This seems to reinforce some kind of laundering/tax evasion scenario. There is little logical reason for one cartridge to go for $13K and another to go for $1.5mm when both are certified excellent condition. It appears that the one going for far more is a product of timing. Someone needed to move a large chunk of money quickly and decided on the Mario cartridge.

How do you figure? Http proxies support various common cache invalidation strategies such as hash-TTL and ETags
