lathiat··on Deleting an S3 Bucket Costs Money
“ For information about Amazon S3 inventory pricing, see Amazon S3 pricing”

Is also mentioned in the article though they don’t calculate the price.

lathiat··on Netflix's new player breaks the ability to modify the seeking of a playing video
The curse of every damn website in the mobile first and responsive some badly world. As a long time Pc user it drives me batty.
lathiat··on What the Irish Ate Before Potatoes
When I think of beans I just think botulism. But that's more to do with preserving them, not sure this within a day or two cooking method applies there. https://www.cdc.gov/foodsafety/communication/home-canning-an...

When I think four chord song I think of Axis Of Awesome :)

Medley of a bunch of pop songs on the premise they all use the same 4 chords.

lathiat··on Linux Perf Profiler UIs
This is a really great round up.
lathiat··on Linux Achieves 5.1M IOPS Per-Core with AMD Zen 3 and Intel Optane
Because hes only using a single CPU core I'm not sure how much the CPU would have helped but you're right he hasn't quantified this.

He's the lead developer of io_uring a new kernel mechanism for doing I/O that is much more effecient for these large IOPS workloads and it itself has been getting lots of optimisation in every recent kernel so it could be both.

lathiat··on Rsync.net Technical Notes – Q3 2021
I remember the same mid vendors and drive batches suggestion for HDD RAID Arrays. Ahhh.
lathiat··on I don't think Elasticsearch is a good logging system
I guess what they want is to use the elasticsearch query language but let it optionally do “expensive” non indexed filtering like a SQL database would let you do.

Without knowing for sure I imagine they originally expected the application side to handle this but many of the current solutions don’t do that. And they expose and overload the elastic search query language as the primary search interface with no additional app logic. The elastic search query “is” the search application.

Making some assumptions but might reconcile the different viewpoints on why it does or doesn’t make sense.

lathiat··on Apple’s app review prevents developer from submitting fix to game for the blind
Chrome for iOS uses the same safari rendering engine as third party browser engines are not allowed. So very curious if it works in iOS Chrome but not Safari as it’s mostly the same.

Also for your specific use case (I realise you were making a point) would be worth using the app I guess.

lathiat··on Napster.com banned at some universities for clogging networks (2000)
And funny because former owner/director Ecclestone seemingly battled against that for so long. Now he's gone, it changed, and they are doing well.
lathiat··on Authenticated Boot and Disk Encryption on Linux
I’ve not used verycrypt, only normal Linux LUKS device mapper encryption, ZFS encryption and windows bitlocker full disk encryption with a paraphrase entered on boot (no tpm). But I haven’t had this problem with any of those.

I’d suggest either your SSD just loses data on power off which is a problem with some SSDs or it’s some veracrypt specific issue that I wouldn’t be familiar with.

Id encourage you to try out one of the above options.

lathiat··on Tenderjit – A JIT for Ruby Written in Ruby
I immediately want to test it out and see if I can get it to JIT itself. I feel evil.
lathiat··on The pitfalls of using SSH-agent, or how to use an agent safely
While helpful it mostly just says “ok to sign” and it’s super easy to accidentally say yes by hitting enter at the wrong time.

I need to look into the original post have wanted this for a while.

lathiat··on Video of Tesla FSD almost hitting pedestrian receives DMCA takedown
From the comments in this thread the Twitter copy was not the original creator of the video. The original creator posted it on YouTube but has since made the video private. And they DMCAd the person that reposted it on Twitter.

I imagine they probably started getting a lot of negative attention.

lathiat··on PipeWire: A server for Linux audio and video streams
Seems that Pipewire and PulseAudio have both just recently fixed this. So yes, but it may not technically matter anymore. But it will be upcoming in a future Ubuntu it's not in the current shipping releases and I'm not sure it will make it into 21.10.
lathiat··on Transport noise linked to increased risk of dementia, study finds
With ear plugs apparently. But then you have an entirely different control problem.
lathiat··on 60x speed-up of Linux “perf”
This is kind of the crux of a long history of these licensing arguments. That dynamic linking is problematic because it potentially creates a derived work. And then you might distribute that derived work.

But shelling out to something or in some cases having an automated script create or download the derived work automatically is sometimes acceptable.

It’s a bit of a silly line in some ways. But it’s a long story.

lathiat··on Linux virtio without the “virt” (2019)
I loved the talk from Rusty Russel at linux.conf.au 2014, who wrote/implemented the VirtIO spec originally. Some funny stories about how you're "supposed" to make standards and what he did (hint: was't what you were "supposed" to do). Good and entertaining watch. Some good technical detail but also very accessible if you know very little about the topic.

lathiat··on Swap on HDD: Does placement matter?
Its been a bit of a complicated problem but memory pressure metrics are now a thing: https://facebookmicrosites.github.io/cgroup2/docs/pressure-m...
lathiat··on Notcurses 2.4
It’s often so easy not to submit these kinds of changes. But 10 years later you still don’t have them.

Seems like a long wait now but is worth it later.

lathiat··on System76 Pangolin Linux-first laptop with AMD internals now in stock
You are totally right. I forgot about this. I went from the sculpt wireless to the sculpt ergonomic and the non detachable keypad was really annoying for that exact reason.
lathiat··on Google's New AI Photo Upscaling Tech Is Jaw-Dropping
Reminds me of some Xerox copiers that actually were changing 6s to 8s with their compression: https://www.theregister.com/2013/08/06/xerox_copier_flaw_mea...
lathiat··on System76 Pangolin Linux-first laptop with AMD internals now in stock
As this thread is highlighting, in my experience there are two kinds of keyboard users. Those that love their numberpad, and those that never use it. There seems to rarely be people in the middle. On desktops it mostly doesn't matter because you can shift the keyboard over relative to the screen. On laptops this translates into people completely loathing or loving the laptop entirely :)

Personally in the never use it camp, and hate these offset laptops. Sometimes its because people do a lot of number data entry spreadsheet style, I can understand that case a little more, however even people that mostly type text I've seen for example will like to enter IP addresses on the number pad for no obvious reason. God speed IPv6 adoption :)

On the other hand laptops are terrible for ergonomics and daily usage anyway, it's unfortunately we've moved so far into laptops from desktops and it doesn't seem so common to dock them and use an external keyboard.. to my feeling mostly because the screen ends up being too small once you push it back to use an external keyboard so then you need an external monitor and the cost and complexity goes up.

lathiat··on Show HN: Blur Webcam Background on Linux
It works for me on Chrome but I had to use Wayland (not Xorg) and then force enable GPU rendering because it's currently blacklisted for Wayland. Possibly relatedly to that blacklist every couple of days (even with rebotos) new tabs in an existing browser window stop rendering content and I have to quit and reload. That doesn't seem to happen on Xorg/without GPU.
lathiat··on eBPF: A curated list of projects related to eBPF
While I don't knwo the actual answer, a good place to look may be one of the eBPF load balancers like "Katran" from Facebook. I imagine it's needing to do that sort of thing. But no idea if it's attaching at the same level. I haven't really explained eBPF outside of tracing.

lathiat··on Raiders of the Lost ARC
This would be a great blog title for something about ZFS.
lathiat··on Green roofs make solar panels 3.6% more efficient
There’s probably 3 issues to look at based on studying solar passive house building principles.

Reflected/absorbed light, thermal mass holding onto absorbed heat over time and water evaporation.

All 3 will come into play here. The roof is likely already light coloured but with high thermal mass that absorbs and holds onto heat it does absorb over the day and radiating that nearby. Covering the roof with a lightweight and insulated material with a high solar reflectivity similar to wood over insulation for a wall would likely get part of the benefit. The other part will be the water evaporating from the plants carries energy back away.

So just painting a concrete roof white probably wouldn’t be equivalent on it’s own though I am really curious whether putting some lightweight siding over an insulation barrier would perform most of the same work.

Consider also ultimately someone needs to maintain all those plants not to overgrow the panels :)

lathiat··on Chip shortage: Toyota to cut global production by 40%
Yep there is an entire risk profile stage that many people leave out. And they apparently correctly estimated the risk in this case. At least for now. Probably wasn't reasonable to estimate such a long supply chain disruption though (that it's still happening now).
lathiat··on Ask HN: Why does Zoom Desktop examine all processes and arguments?
The discord snap blocks this with apparmor by default unless you connect process-control. But it also fills your kernel log with audit denials.
