I insert the USB stick LTE modem into my Linux laptop. I thought it was going to take a lot longer to get the internet on this device. 😭 I might need to tweak settings or download the drivers and compile it.

Linux sends a notification: 'New modem found.' What? No way.

So, I go to the network settings panel, and there's an option to connect to the Internet called “Mobile Internet”. I click on it.
I'm online, and I'm speechless 😶 The year of the Linux desktop is already here, at least for me!

최보식을 비롯한 긁우들은 거기에 보태 네이버가 북한 례성강 일대를 지도에서 삭제했다고 우기고 있는데, 위성 사진 (지들이 빨간색으로 표시한)을 자세히 보면 건천같이 된 부분이 보입니다. 사실은 뭘까요? 진짜 건천 맞습니다. 2018년, 남북공동수로조사 당시 모래가 너무 쌓여서 50cm 수심만 있어도 들어가는 소형 선박조차 들어가지 못한다고 조사된 바 있습니다. 사실상 막힌 길 맞다는겁니다. 여기서 뭔 폐수가 방류 어쩌고 해요.

Not even bad the latency (this is just about latency, not overall bandwidth which reaches the full 4.9Gbit via 2x 2.5Gbit links).

Taken inside a Debian VM running on a Proxmox node connected to the storage:

GMKTec G9 NAS
2x 2.5Gbit
NFS 4.2 (with pNFS)
2x WD Back SN7100 NVMe
Mirror mode ZFS

While this are already pretty awesome latencies, let's see how it performs with SPDK and NVMe-oF (TCP).

Woodworkers are the most welcoming community I know of. You're talking to a master craftsman but they're still excited to see your garden planter.

On the flip side, the worst are probably electronics & math folks on Stack Exchange & Reddit: "get better before you talk to us".

Working theory: toxicity grows in proportion to the distance to wood

링크는 안 올립니다. 매일신문 최훈민이 또 예성강 방사능이 후쿠시마 핵폐수 초과 어쩌고 하는 루머를 강화하고 있는데요. 사진 자세히 봅시다. 간이측정기를 돌 위에 올려서 재고 있죠? 간이측정기의 신뢰성도 문젠데, 한반도 화강암은 대다수 자연방사능을 내뿜습니다. 거리를 두고 떨어뜨려 재야 해요. 저런 작자가 기자라고 설치고 다닌 조선일보, 조선NS, 매일신문의 민낯입니다. 니들이 언론이에요?

The @datarescueproject.orgData Rescue Project needs our help preserving American history.

"Real history is not just happy stories. But the Secretary of the Interior is asking Americans to report signs in the Parks that “inappropriately disparage Americans past or living.”

Join our effort to build a community archive of the signs, exhibits, and texts that could soon disappear from our national parks."

re: blocklists, FediNuke

thinking about winding down my shared blocklists tbh. it’s draining and tons of almost entirely unpaid labor to find, archive, and catalog receipts. one awesome person pays a dollar a week but it’s really not enough to justify this effort.

i might write a retrospective and advice for anyone else who wants to try.

https://seirdy.one/support/ if you want to convince me to keep going.

Man, imagine if a professional fiction writer wanted to make the point that the tech community, even the ones who say they’re anti-AI, are embarrassingly malnourished in the arts. Imagine if they posted an “email” they received from an “AI bro” that was blatantly, fractally satire using the idea of the hate-reader email as a framing device, and proceeded to laugh their toes off at all the replies from techies engaging with it as a literal email from a real AI bro to be logically debated point-by-point and not a work of satire underscoring the non-quantifiable value of the arts. Wouldn’t that give us all something to think about. For legal purposes this post is speculative fiction

“Source code provisions” are an essential aspect of copyleft licenses — even for those designed for non-software works.

Much work remains to determine how to draft a “source code provision” for non-software. Copyleft-next hopes to get there eventually. Maybe could help!

I have deleted a few mastodon posts recently, because they were too pessimistic. In general when I delete posts here it's because I was either being rude (and I apologize) or too pessimistic. We don't need more pessimism. We need pragmatic, hopeful optimism with a path of action.

After 5 years of development, Alpine Linux just merged apk v3 into edge! 🎉

There are some fantastic things in there, such as downloading packages before installing them (which we enabled by default), so that a flaky internet connection can't ever destroy your system again.

Also the version string apk reports changed slightly, leading to a bogus "downgrade attack" message in pmbootstrap:

> ERROR: Downloaded apk-tools-static-3.0.0_rc5_git20250613-r0.apk, but the apk binary inside that package reports to be version: 3.0.0_rc5_git20250613-r0! Looks like a downgrade attack from a malicious server! Switch the server (-m) and try again.

This and other incompatibilities have been fixed in pmbootstrap 3.5.1 and higher:

Today I've released version 1.5.3 of Dowstodon, my Mastodon client for Windows. It's got some neat improvements for the system notifications and a better look when transparency is disabled, but the biggest addition is the ability to search users by name on user's lists e.g. the following list.

I know it might be annoying to some, but I've also added a donations section the settings page. If you use the app and enjoy it, and have the means to, please consider donating to help development of it.

Screenshot of a window showing the list of users I follow on Mastodon. At the top of the window is a text box which allows the user to filter the list according to what's typed.

ok, så jeg har allerede testet ultimate en periode for en liten stund siden, og opplevelsen var opp og ned, men generelt god — en kan koble på og spille der hvor en kan installere en geforcenow app — en kan feks også koble på en og spille de spillene som tilbys der — akkurat de spillene kan en også spille med der en kan installere den appen, men appen kan ikke spille steambiblioteket, bare synkronisere hvis du også kjøper spillene gjennom — og akkurat det er jo helt absurd, men men … så geforcenow er en bedre app hvis en skal spille egne spill — men nå tar jeg en kjøretur med som tilbyr noe av det samme som nvidia gjør med geforcenow — appen til shadow er i beta og de har ikke app til samsungtv, men de holder til i Europa (jeg registrerte meg i Danmark siden de av en eller annen grunn ikke har signup skjema for Norge)

Med shadow er det ikke bare spill — de tilbyr også arbeidsstasjoner i skyen

og siden jeg ikke har en windowsmaskin lenger, så er det naturlig å se om det kan være en løsning

jeg testet ut tidligere i vinter/vår, og det ble unaturlig dyrt i drift

jeg har , men det blir en begrenset opplevelse i sammenligning

prisen for shadow er i utgangspunktet sammenlignbar med prisen til microsoft, men prisen til microsoft skalerer i et system det er egen utdanning for å forstå — nå får vi se hvordan det er med shadow

det er sommersalg på gamingproduktene deres, så switcher jeg til et pro produkt hvis nødvendig
