Wow! At first, I expected this to be a demonstration of an AI playing rocket league, but I rapidly realized this is actually a model simulating rocket league. Wild! It feels just like the real game.

Feather appears to just be block compressed Arrow IPC [1]. Lightweight compression techniques generally achieve two orders of magnitude faster random access compared to block compression. That’s one of the benefits of formats like FastLanes

cppreference says [1]: A prvalue of floating-point type can be converted to a prvalue of any integer type. The fractional part is truncated, that is, the fractional part is discarded. - If the truncated value cannot fit into

I think one of my favorite examples of avoiding decompression for great profit (really: health) is PLINK. If you’re not aware, it’s a tool for doing statistical genetics (things like quality control but also inferring population structure,

We’ll post a blog post soon with specific, benchmarked numbers, but, in this case, you can have your cake and eat it too! The compression and decompression throughputs of Vortex (and other lightweight compression schemes) are similar or bet

Thanks for introducing me to these other formats! I hadn't heard of them yet. All three of fst, JDF, and Vortex appear share the goal of high throughput (de)serialization of tabular data and random access to the data. However, it is no

Yeah we should be more clear in our description about how our footers differ from Parquet. Parquet is a bit more prescriptive; for example, it requires row groups which are not required by Vortex. If you have a column with huge values and a

by danking00 2y ago
Yeah, you and us are on the same page (heh). We don’t want the format to require row grouping. The file format has a layout schema written in a footer. A row group style layout is supported but not required. Specification of the layout will

Unless I’m misreading, the first two references support the idea that vacancy rates are too low but don’t comment on why . The last reference indeed argues in favor of too much financialization of housing units but that blog is also trippi

Thanks for the reply and clarification! That’s an impressive throughput. Am I interpreting the behavior correctly to think that: your code has one branch per int and that branch will be predicted well when your integers are all of similar m

If I’m following, this presents an alternative format and implementation to LEB128 which encodes and decodes substantially faster. Notably, the implementation is quite simple. Cool! And agreed that modern CPUs really suffer from branches.

I think it might help readers to include a narrative about an example application. Perhaps I’m in the minority but I tend to think of Bloom filters as a way to reliably know something isn’t in a set (e.g. so as to not run an expensive di

I was surprised by the last clause in your last sentence, but you’re absolutely right. https://www2.census.gov/geo/docs/reference/ua/ua_list_all.tx... LA edges out NYC: 7000 to 5300. Presumably in indivi

I gathered a table for Google and Amazon's options. I do not have experience with on-prem solutions so I don't know how to compare these prices to the cost of owning and operating hardware. I'm sure its cheaper over time for

It'd be interesting to see a peak-sequential-bandwidth by cost-per-gigabyte plot. The number I keep in my head is 500 MiB/s, but you're right that there are much faster drives out there [1]. Of the public clouds: Google'

Thanks for all your comments thus far! I have an axe to grind with the US immigration system but it’s best to grind it on a stone of facts. Yeah, I was a bit loose with the parents situation. I made a general comment based on a specific ci

For India alone, Wikipedia says ~8% or ~100 million have a BS. I was more focused on PR/citizenship in my post. I do not know what qualifies you for an H1-B. In the second point, I only have an imprecise opinion which is that I’d rathe

Fair on the first point, I’ll adjust the text to clarify the need for a BS. On the second point, first claim, you can be in an EB-1 queue without an H1-B (e.g. OPT or TN [1]). On the second claim, I admit to not knowing someone who is in t

I suppose majority is factually true, but I think it’s worth being specific that nearly three billion people are in that situation.

People who gain citizenship are no longer in a precarious visa situation nor tied to their current employer. Moving people off visas and into PR/citizenship would seem to me to remove downward pressure on salaries. Heck, workers with P
