Exploring a parallel syntax with #rdatatable

```
data |>
_[, .(x = async(long(x))), by = .(group1, group2)] |>
collect_async()
```

Is syntax sugar for

```

_[, .(x = list(future::future(long(x)))), by = .(group1, group2)] |>
_[, x := future::value(x[[1]]), by = .(group1, group2)] |> […]

This was quite successful on fedi, so might post up here. Good people of the #rstats community, I have need of work. I don't need much, but some income while I keep writing and doing promo stuff is important. Given my personality, I think the R community would be a good place to look. If you know of

I'm tasked to migrate a small organization to @libreoffice but the forms from MS Access don't come over to LO Base. Is there a way to automatically import the forms, or I actually have to manually recreate them all by hand?

🌍 How trustworthy are your spatial predictions?

In my talk for the Rome R Users Group, I showed practical ways to evaluate where spatial predictions are trustworthy, and where they aren't.

How spatial sampling methods affect the variance of your mean estimate when spatial autocorrelation is present.
https://dosull.github.io/posts/2025-11-14-gia-chapter-2A-spatial-autocorrelation/
Shows four density charts. Each chart represents a sampling method: poisson, grid, evenly spaced, and clustered.. Each chart shows two densities: random (no spatial autocorrelation) and smoothed (spatial autocorrelation). Grid and evenly spaced show too narrow variance estimates while clustered shows too wide of a variance estimate.

The GreyNoise IP Checker (https://check.labs.greynoise.io) now gives geolocation info in the header (if the IP was in GN) and populates a 90-day timeline with a summary of tags.

GreyNoise IP Check results showing malicious activity detected for IP address 89.248.163.216 located in Amsterdam, Netherlands. The IP, owned by IP Volume Inc, has been classified as malicious with observed activity from February 2022 to October 2025. Activity calendars show consistent scanning behavior throughout July, August, September, and October 2025. Tagged activities include Go HTTP Client, Open Proxy Scanner, Recyber Project, SOCKS5 Proxy Scanner, and Web Crawler. A warning banner alerts users that the IP has been observed sending potentially malicious traffic. GreyNoise IP Check results for IP address 34.185.165.52 located in Frankfurt am Main, Germany and owned by Google LLC. A warning banner indicates possible spoofed traffic detection, explaining that the IP may have appeared in scanning activity using spoofed source addresses. The 'Don't Panic!' section clarifies this likely means the IP was used as a fake return address in network scanning, similar to spam email spoofing. Three key points explain: the scanning traffic probably didn't come from this network, attackers may have used the IP as a decoy, and this typically doesn't indicate compromise. Recommended actions include monitoring for unusual outbound traffic, ensuring proper firewall configuration, and contacting the ISP if suspicious activity is noticed. GreyNoise IP Check results for IP address 169.150.198.68 located in São Paulo, Brazil and owned by Datacamp Limited. A blue banner alerts that VPN is detected, noting the results may reflect the VPN provider's IP rather than the actual network. A warning banner states the IP is in the GreyNoise database with 'unknown' classification, indicating it has been observed by GreyNoise sensors scanning the internet. The 'What does this mean?' section explains this could indicate a compromised device or network, misconfigured software making excessive connections, or legitimate security scanning tools. Recommended actions include checking devices for malware, reviewing network activity, contacting the ISP's security team, and considering taking a screenshot for the ISP. An 'Observed Activity In Last 90 Days' section is collapsed.

@erc_bk Decided to improve upon this a bit (with some Claude help). The code is in this gist, https://gist.github.com/ercbk/8d8803a3b22d21a4a871dc8ae967cd6a. Not as comprehensive as skimr, but takes advantage of arrow's lazy evaluation. This only uses around 214MB of RAM. #rstats
R code that shows the summary stats output of the skim_arrow function. Code for this function is at the gist link.

Didn't know that {skimr::skim} worked an arrow object. It's pretty cool, but it hits your RAM pretty hard. That's only a 70MB directory of parquet files, and my RAM usage went up by ~1.3GB. #rstats Code: https://ray.so/fCoXwso
