zerd··on Over 20k servers have their iLO interfaces exposed to the internet
HP Microserver Gen8 with iLO from 2014 also had generated admin password.
zerd··on 717 Gigapixel Image of Rembrandt's Nightwatch
In this video [1] he mentions that each 100mp image is around 600MB, which aligns with the size of the 4-shot multi-shot mode of the H6D-400C MS. 8439 photos 579MB would be around 4.7TB in raw format.

The cost of the camera is a small drop in the bucket versus the rig and work gone into this.
zerd··on Ask HN: Has Google search become quantitatively worse?
Google now also has an extreme recency bias. Most things I search for will give top results for recent SEO optimized blog posts/Youtube videos instead of established authoritative resources. If you search for something that happens to overlap with a recent movie name, good luck, it'll drown. And I constantly "have" "to" "search" "like" "this" because Google thinks it knows better than me.
zerd··on Making the dislike count private across YouTube
I press Right arrow key 3-4 times and it skips it.
zerd··on We saved millions in SSD costs by upgrading our filesystem
There's also opportunity cost. What if you instead of hiring a team of 10 people (probably need more, managers, distributed geographically etc), you hire more developers, marketing, sales and increase revenue. So instead of saving $2M, you make $3M more revenue. Making up numbers of course, but companies can estimate this. If that's the case it makes sense to keep paying AWS, until the ratio changes, and then they can cut costs.
zerd··on Spending $5k to learn how database indexes work
Have a friend who had a BigQuery query that ended up costing $3k each time. It ran for only a minute, because BigQuery chews through data really fast. But you don't realize that when you push the run query button. And there's no spend guard rails. They switched to pay for given amount of parallelism after that.
zerd··on Spending $5k to learn how database indexes work
If you create an inefficient internal combustion engine, you'd know because you have to go to the gas station every 5 miles. In this case it would be like someone was filling up the the gas without you knowing, and then a few weeks later you get the bill, and then you realize that your engine is inefficient.
zerd··on Feds order Google to track people searching certain names or details
Also "ied package" and "eagle feather" according to the docs (from different cases) linked in https://www.forbes.com/sites/thomasbrewster/2021/10/04/googl...

Next up, "winnie the pooh" and "tank man".

zerd··on Axboe Achieves 8M IOPS Per-Core with Newest Linux Optimization Patches
Didn't see the t/io_uring script, but the branch they're working on is here https://git.kernel.dk/cgit/linux-block/log/?h=perf-wip
zerd··on Freqfs: In-memory filesystem cache for Rust
I remember watching a talk about that: https://www.youtube.com/watch?v=wN6IwNriwHc

zerd··on Are software engineering “best practices” just developer preferences?
If only building a bridge in your garage could make you a billionaire. People would build bridges like crazy.
zerd··on Mosquitto: An open-source MQTT broker
Are you sure it's MQTT adding the delay? From my experience that part is pretty much instantaneous, but processing though Home Assistant, and in my case zigbee2mqtt does add some delay.
zerd··on A search engine that favors text-heavy sites and punishes modern web design
It's also because that's a way of trying to copyright protect recipes, which are normally not copyright protected.

> “Mere listings of ingredients as in recipes, formulas, compounds, or prescriptions are not subject to copyright protection. However, when a recipe or formula is accompanied by substantial literary expression in the form of an explanation or directions, or when there is a combination of recipes, as in a cookbook, there may be a basis for copyright protection.”

zerd··on Show HN: Time travel debugger for web development
But typically it will throw an exception _after_ the interesting code happened. For instance it might throw a NullPointerException, but you want to know what set it to null in the first place. With breakpoints you have to suspend on exception, and then add additional breakpoints earlier in the code, and then rerun the code. With rewind you can just step backwards.
zerd··on Steve Jobs: Let's force Amazon to use our payment system (2010)
https://en.wikipedia.org/wiki/Whataboutism
zerd··on Scanning “private” content
Or look up how to handle kill process or sacrifice child.
zerd··on How we trace a KV database with less than 5% performance impact
Tracing is at a different level of detail. For instance you can see which user and specific query is missing caches and spending a lot of time waiting for IO. Unless you inspect local variables while walking the stack I don't see how you'd get that just just profiling. But a combination would be preferable (some observability tools have started on this, e.g. the profiler will tell the tracer where add additional instrumentation).
zerd··on Transfer.sh – Easy file sharing from the command line
Neat! This looks like the closest thing to what I'm looking for when I ssh somewhere and I don't want to cat the file, mark, scroll, scroll, scroll, scroll, copy, and paste into a gist.
zerd··on GitHub Copilot is not infringing copyright
You're assuming Copilot is the only AI-powered autocomplete?
zerd··on GitHub Copilot
And if what the economists needed to do could be programmed trivially with the help of AI then their job is probably also replaceable by AI.
zerd··on Ask HN: Best “I brought down production” story?
And thus DHCP snooping was born.
zerd··on Hacker deleted all of NewsBlur’s Mongo data and is now holding the data hostage
Docker will happily override your firewall rules even with infrastructure as code. We block the AWS/GCP metadata IP to avoid potential exploits using that to pivot, but Docker also manages to override that sometimes, so we have a cron job that re-applies it.
zerd··on Star Citizen Progress Tracker v1.0
Falcon 9 1.0 was announced in 2005, launched in 2010 and cost about US$300 million [0].

Star Citizen was announced in 2010 and has raised over US$300 million [1].

It's wild to me that it takes twice as long and similar amount of money to make a game launch than a rocket launch.

zerd··on ZFS fans, rejoice – RAIDz expansion will be a thing soon
A colleague who was used to other UNIXes was transitioning to Linux for a database. He saw in free that used was more at more than 90%, so he added more ram. But to his surprise it was still using 90%! He kept adding ram. I told him that he had to subtract the buffer and cached values (this was before free had the Available column).
zerd··on Most hospitals aren't complying with price transparency rule
Plus out of network emergency visits, which isn't uncommon https://www.kff.org/health-costs/press-release/about-1-in-6-...
zerd··on Complexities of e-mail validation logic
Etrade lets you create 32 character password, but if you enable 2FA you suddenly can't login because apparently they concatenate them together and then check the length. So make sure your password is max 26 characters. (they might've fixed this but I haven't tried).
zerd··on Judge in Fortnite case holds Tim Cook's feet to the fire
Apple also makes a 30% cut of every scam app, so they're not in a hurry to shut them down.
zerd··on Scaleway announces measures against abusive Chia plotting and farming
Sounds like the classic https://en.wikipedia.org/wiki/Protection_racket on a global scale.
zerd··on Using a GPU Boosts Analytics Performance by 10 to 150 Times
But if you have to hit the buffer pool (memory) then you have to cross the PCIe bus. With fast NVMe storage you might get similar speeds going directly to storage (e.g. DirectStorage) https://news.ycombinator.com/item?id=25956670
