It statrs with "At the same tiem" so it's consistent.


This is completely off topic but I'm shocked that zdnet autoplayed a video with audio on after I opened the page and scrolled down a little. Incredible that we still have websites whose primary purpose isn't playing audio automatically play audio. There's no way this doesn't annoy a vast majority of users.

This phenomenon terrifies me greatly - how large organisations can be ignorant of the basics of their purpose. I believe it is one and the same mechanism of collective incompetence, which can affect both a media company, a school, or a government. It's as if the humanity, under any system, were bound to create inhospitable conditions for one another.


Companies are not “ignorant of the basics of their purpose”. The basics of their purpose is to make money and increase value for shareholders. There is nothing in their core purpose that benefits you as a user or that says they shouldn't annoy you.


I am aware that the purpose of an overwhelming majority of companies is to earn money. Does auto-playing their own video with audio increase revenue? It's not an ad someone is paying for.


You can use a browser from a non-ad company that lets you block auto-played A/V.

As demonstrated, crisps are more valuable to the society than art.


That's too reductive. Vacuum full isn't just slow, it exclusively locks the table for the duration of the vacuum and is basically a no-go when the database is in use.


And make sure your `random_page_cost` is about 1.1 if running on an SSD or if >~98% of your hot pages fit in memory. Rather than 4 by default which makes the planner afraid of using indexes.


> Python: ~60% waste (Mostly sized for startup spikes, then idles empty).

I understand we're talking about CPU in case of Python and memory for Java and Go. While anxious overprovisioning of memory is understandable, doing the same for CPU probably means lack of understanding of the difference between CPU limits and CPU requests.

Since I've been out of DevOps for a few years, is there ever a reason not to give each container the ability to spike up to 100% of 1 core? Scheduling of mass container startup should be a solved problem by now.


I don't think there is. You should set both and limit doesn't need to match request for CPU.

Your limit should roughly be "what should this application use if it goes full bore" and your request should be "what does this use at steady state".

At least at my company, the cluster barely uses any CPU even during the busiest hours. We are fairly over provisioned there because a lot of devs are keeping limit and request the same.


CPU bursting is safe you just get throttled. Memory bursting is dangerous you get OOMKilled.

That's why Python numbers look so bad here devs set the request high enough to cover that initial model loading spike so they don't crash during a rollout, even if they idle at 10% usage afterwards.


What makes you think they're talking about CPU? It reads to me like it's memory.


Two things - the word "idles" and the nature of CPython's allocator which generally doesn't return memory to the OS but reuses it internally. So you cannot really "spike" memory usage, only grow it.


I wonder what would happen if someone evolved a circuit on a large number of FPGAs from different batches. Each of the FPGAs would receive the same input in each iteration but the output function would be biased to expose the worst-behaving units (maybe the bias should be raised biased in later iterations when most units behave well).


Either it would generate a more robust (and likely more recognizable) solution, or it would fail to converge, really.

You may need to train on a smaller number of FPGAs and gradually increase the set. Genetic algorithms have been finicky to get right, and you might find that more devices would massively increase the iteration count



So I downloaded this file... Apparently it is:

  $ file -b grecaptcha 
  Mach-O universal binary with 2 architectures: [x86_64:\012- Mach-O 64-bit x86_64 executable, flags:<NOUNDEFS|DYLDLINK|TWOLEVEL|PIE>] [\012- arm64:\012- Mach-O 64-bit arm64 executable, flags:<NOUNDEFS|DYLDLINK|TWOLEVEL|PIE>]
I cannot perform a dynamic analysis as I do not have macOS. :(

May anyone do it for me? Use "otool", "dtruss", and "tcpdump" or something. :D Be careful!

The executable is available here: https://www.amanagencies.com/assets/js/grecaptcha as per decoded base64.


No need - it's detectable as Trojan:MacOS/Amos by VirusTotal, just Google the description. Spoiler: it's a stealer. Here [0] is a writeup

> AMOS is designed for broad data theft, capable of stealing credentials, browser data, cryptocurrency wallets, Telegram chats, VPN profiles, keychain items, Apple Notes, and files from common folders.

Thank you! Nothing too interesting. :(

Got anything better? :D Something that may be worth getting macOS for!

Edit: I have some ideas to make this one better, for example, or to make a new one from scratch. I really want to see how mine would fare against security researchers (or anyone interested). Any ideas where to start? I would like to give them a binary to analyze and figure out what it does. :D I have a couple of friends who are bounty hunters and work in opsec, but I wonder if there is a place (e.g. IRC or Matrix channel) for like-minded, curious individuals. :)


You can spin up an ssh server on GitHub Actions macOS runner or most cloud providers you can rent a box

The binary itself appears to be a remote-access trojan and data exfiltration malware for MacOS. I posted a bit more analysis here: https://news.ycombinator.com/item?id=45650144


Ooh, first time I am hearing of https://dogbolt.org. Thanks for that! :)


Not long until the payloads will look like:

Sorry not to have made this clear: I am not a frontend developer. I'm a backend/infra developer who's forced to work on a React app abandoned by a frontend developer who incorporated their own wrappers-of-wrappers-of-wrappers.

Meanwhile the client is telling me is virtually impossible to find frontend devs willing to write HTML.


Almost any developer familiar with HTML would be willing to write HTML if they were paid similarly to making something flashy in React (to use your example)

Because I don't believe this is a real issue in the marketplace, I will write HTML for your client if they are truly unable to find someone. Writing HTML would be the easiest paid job I could imagine in my field right now.
