Infrastructure: everything you don't see until it breaks

An electric car is rather quiet, which is great. Except when you're driving around with an infant who sleeps well only to the sound of a humming car engine. So... I use a smartphone app generating white noise, jungle sounds, a fireplace, a hair dryer and... an internal combustion engine. I play that sound through Bluetooth to simulate a noisy vehicle inside. What a time to be alive!

From https://blog.vlt.sh/blog/the-massive-hole-in-the-npm-ecosystem

• a #npm package's manifest is published independently from its tarball
  manifests are never fully validated against the tarball's contents
• the ecosystem has broadly assumed the contents of the manifest & tarball are consistent
• any tools or insights using the public registry are susceptible to exploitation/likely inaccurate
• bad actors can hide malware & scripts in direct or transitive dependencies that go undetected

#Musk and #Shapiro showing imaginary tweets by Jews from 1940s is the new low...

"Musk showed fake tweets (https://bsky.app/profile/joshuajfriedman.com/post/3kjmbimymg42t) he created of people sharing photos of Nazi attacks on synagogues, supporting Jewish resistance fighters, and pushing back against #Holocaust deniers. There was even a tweet from the “official” #Auschwitz account claiming Jews there were “thriving”—only to have a community note debunk that claim" https://newrepublic.com/post/178324/auschwitz-elon-musk-social-media-prevent-holocaust

We can make fun of #JavaScript as long as we want, but 0.1 + 0.2 not equal 0.3 is not JS's bug. It's because it follows a standard, like many other languages:

$ node  
Welcome to Node.js v18.12.1.  
> 0.1 + 0.2  
0.30000000000000004  

$ python3  
Python 3.11.6  
>>> 0.1 + 0.2  
0.30000000000000004  

$ irb  
3.0.0 :001 > 0.1 + 0.2  
 => 0.30000000000000004  

$ jshell  
| Welcome to JShell -- Version 19.0.2  
jshell> 0.1 + 0.2  
$1 ==> 0.30000000000000004

I struggle to find the benefits of #Spring #R2DBC. It's a full rewrite of #JDBC API using non-blocking I/O. However, typical application shouldn't open more than a handful of DB connections. So, just a few threads blocked on I/O (plus some threads queued up) shouldn't be an issue. Unless you want to be purely reactive or you are connecting to massively scalable database. But in that case, virtual threads come in handy. So what's the point? #Java #reactive
