ZeroCool2u··on Show HN: Faster FastAPI with simdjson and io_uring on Linux 5.19
If anything you'd probably want to send it in Arrow[1] format. CSV's don't even preserve data types.

ZeroCool2u··on Show HN: Faster FastAPI with simdjson and io_uring on Linux 5.19
Though I have read a bit about simdjson I'm not super familiar with how it works, so please forgive me if this is a silly question.

Since simdjson is where a lot of the performance benefits come from here, would you need to compile the underlying C/C++ code on the machine that you're deploying on to make sure that simdjson is using the correct instruction set? Like what if the processor I'm compiling on has AVX-512 support, but the target machine for deployment doesn't? Does it just generate the machine code for all instruction sets and then can automatically choose to use the optimal instructios at runtime? Or does it just have to compile every time you pip install the package? I could see this being awkward if you're building a docker container perhaps, but maybe I'm just woefully uninformed.

ZeroCool2u··on Pandas 2.0 and the Arrow revolution
I think if anything pandas may get additional vectorized operations, but from what I understand Polars is almost completely Rust code under the hood, which makes multiprocessing much easier compared to dealing with all the extensions and marshaling of data back and forth between Python and C/C++ that pandas does.
ZeroCool2u··on Pandas 2.0 and the Arrow revolution
Yes, Marc talks extensively about the new interop options between Pandas and Polars enabled by the pyarrow backend.

You're right, something weird happened when I pasted the link in to submit it. Maybe a bug in Chrome on Android, because I just tested it again and found it only copied the link to the blog and not the specific post.

If Dang or any other mods see this, please correct the link.

ZeroCool2u··on LED lighting badly suppresses human melatonin production at night
One of my favorite features on my Pixel 7 Pro is the "Extra Dim" feature, especially since the Netflix app has started enforcing a minimum brightness level that's much too high in dark environments.
ZeroCool2u··on Ubuntu Flavors Agree to Stop Using Flatpak
I think Steam specifically does quite a bit more complicated stuff that can affect the rest of the system just to support games than most other pieces of software. It has its own built-in update mechanism, which I think makes it one of the few pieces of software I'd avoid using the package manager for.
ZeroCool2u··on YouTube CEO Susan Wojcicki is stepping down
One thing I haven't seen anyone mention is the recommendation engine is much better in YT Music than Spotify IMHO. I've found a surprisingly large number of new artists that I enjoy and it's solely due to YTM's recommendation engine. Really obscure stuff that I just wouldn't have found otherwise.
ZeroCool2u··on The Adoption of Rust in Business
Interesting, I was always pleasantly surprised at how few dependencies the GCP Python bindings pulled in.

You are hand-rolling HTTP wrappers though, so I think we have slightly different perspectives :)

ZeroCool2u··on The Adoption of Rust in Business
One of primary reasons that Rust adoption has been stifled at an org I work with is that the cloud provider we use (GCP) doesn't support Rust with client libraries or SDK's. We know there are 3rd party providers, but they're not willing to go without GCP official support and I can't blame them.
ZeroCool2u··on Choropleth maps with ggplot and R
Sure, maybe. I wouldn't bother though, because it's basically a single line in Plotly to do this. (Though I freely admit there are quite a few parameters for that one line.) See: https://plotly.com/python/mapbox-county-choropleth/#using-ge...
ZeroCool2u··on Release engineering is exhausting so here's cargo-dist
"Alright so I've given you The Pitch of how this should work, but how does it actually work today? Well, yes, I wouldn't announce this if not -- but there's a lot of future work to do! Actually no I take that back, it's definitely perfect. Those familiar with my broader oeuvre know this will absolutely be a perfectly crafted demo that avoids all the sharp corners of cargo-dist!"

One of the most honest paragraphs ever written.

Seriously though, great tool and great write up. I hope something like this lands as an official cargo feature. Coming from mostly Python land at work with crazy dependencies for TF and PyTorch GPU support (On Windows sometimes!) makes me super jealous.

ZeroCool2u··on Choropleth maps with ggplot and R
I make extensive use of geopandas and plotly for doing mapping and it’s very difficult for me to imagine it could get all that much easier. Dump my geo data frame in and specify which columns to use and boom you’ve got a fully interactive map with Open Street Maps data underneath. It even has a variety of themes to choose from!
ZeroCool2u··on Sharing Your Netflix Account
This is easily automated using Ombi and the other tools folks have mentioned in other comments.
ZeroCool2u··on Sharing Your Netflix Account
She's not the _only_ user, it's just that my "households" usage doesn't justify the expense and effort.
ZeroCool2u··on Sharing Your Netflix Account
I'm not sure I agree. If the choices are:

I can keep my account and downgrade my plan and then pay for a separate account for my Mom, then they would make about the same or even less money. They certainly won't be getting any ad revenue from either account.

I can cancel my account outright and get my content through alternative methods where Netflix is not compensated.

It seems to me the choice is obvious here and the calculus doesn't swing in Netflix's favor. Perhaps for the majority of the subscriber population it will, but that's a bit of a gamble when my generation and really every other generation after grew up knowing how to pirate whatever they wanted.

ZeroCool2u··on Sharing Your Netflix Account
Yes, that is the last paying option left. Obviously, that's not appealing though, so I'm more likely to seek out alternatives.
ZeroCool2u··on Sharing Your Netflix Account
It wasn't necessarily cheaper in terms of effort until now and I prefer to support the content creators. But I already pay over $20/month and for what? I barely use it, same with my Wife. The one person that does use it the most is getting blocked, so I have a hard time seeing a reasonable alternative.
ZeroCool2u··on Sharing Your Netflix Account
My Mom lives on the West Coast while we live on the East. She's almost 70 and on a fixed income, so I pay for Netflix access for all of us and I'm happy to do so.

However, if they block her access I can't see any reason to keep my 4k plan. I can get anything we want on a Plex server and give her whatever she wants to watch that way.

I was already on the fence with the lack of content on Netflix, but this may just be the straw that breaks the camel's back.

ZeroCool2u··on Microsoft Azure Outage
This is one of the single most comprehensively intense demo projects I've ever seen. I did a multi day AWS Data Lab for work once and it wasn't this comprehensive.
ZeroCool2u··on Replacing Pandas with Polars
I use it with plotly and it's great.
ZeroCool2u··on Quiet, ultrathin AirJet solid state active cooling chips could replace fans
The founder mentions the dust proofing as a nice side effect of the high back pressure, but I'm wondering if that might actually be necessary to prevent the mechanical membranes from getting jammed with gunk and failing over time.
ZeroCool2u··on Bank of America has lost Zelle transfers for many customers
I use Google Pay with my wife and it works great. Never had an issue.
ZeroCool2u··on Apple HomePod 2nd Generation
Seems like Apple executed the way Google should have with their Google Home Max. They've added stereo pairing, so you can have two of them sync up together and then connect them to an Apple TV 4k and you basically get a pretty nice wireless sound bar with Dolby Atmos enabled.

Still, at $300 per pod, I really need Siri to do better than the "dumber than a bag of rocks" vibe she currently gives off for this to be at all tempting.

As someone that does applied DL for work, especially NLP, I just don't understand what Apple is doing with Siri. It's like they see low user engagement metrics with Siri and assume it's because people don't want it. Instead, everyone I know that's an Apple fan uses Google Assistant, because it just works most of the time.

ZeroCool2u··on Intel Core i9-13900T CPU benchmarks show faster than 12900K 125W performance
I'm not sure it's fair to say the 5950X is a good point of reference. The 7950X has been out for quite some time at this point and the 7950X3D is announced and expected to be available next month.
ZeroCool2u··on System76 AMD-Only Laptop Returns
Try using Wayland and see how the touchpad feels. Should be much better. Nvidia makes it problematic to use Wayland, but it’s a good test to verify the quality of the trackpad hardware.
ZeroCool2u··on Wing: A cloud-oriented programming language – request alpha access
Really both. I'd prefer to be a bit more familiar with the underlying infrastructure and also I'd like to use GCP products, BigQuery is definitely a big one though!
ZeroCool2u··on Wing: A cloud-oriented programming language – request alpha access
I'm very excited about Shuttle, I've been watching it for a while and it looks fantastic. The only thing I'm looking for is support for GCP, but I don't see that happening until Google makes official Rust client packages.
ZeroCool2u··on Fusion energy breakthrough by Livermore Lab
I'm curious, when you're talking about the SMR projects, does that include the Natrium reactors from TerraPower? I think they're backed by the Gates Foundation? Those seemed pretty interesting to me as a nuclear layman. Also, I don't know a lot about Bill Gates, but he does seem like the kind of guy that if they showed some real success, boondoggle or not, he'd be willing to brute force his way past those issues by throwing money at the problem.
ZeroCool2u··on LG announces the first 1440p 240Hz OLED monitor and it only costs $999
I think they're, somewhat poorly, referring to what is called a "G-Sync Ultimate" monitor. These monitors contain an expensive proprietary hardware module that facilitates frame syncing. It's not necessary though, Nvidia firmly lost the marketing battle to AMD there. This monitor has the frame syncing support you want.
