Secrets of Performance Tuning Java on Kubernetes - The Article (Part 2)
In Part 1, we saw that the JVM doesn’t always play nicely with containers, and we must be aware of that, and adjust accordingly. Now let’s invite Kubernetes to the party and see how things get really ...

Hello Internet! Ready for KubeCon? 🔥

To celebrate last week’s launch of #Agent0 - the integrated Agentic #AI inside #Dash0 - we made something we’re pretty stoked about.

At #KubeConNA 2025, we’re giving away five custom MtG-style cards. Find us at booth 710 - first teaser: The Seeker & The Oracle!

This was on for me when I checked. If you use LinkedIn, it's worth checking on. I definitely don't want my posts there being used as training data.

Dash0 raises $35M #SeriesA!🚀

#Observability is too noisy, complex & expensive. We started Dash0 to fix that - and 300+ customers joined us.

Now we’ve raised $35M in Series A led by Accel & Cherry Ventures, with DIG Ventures.

Thanks to our investors & angels for the support!

So much, so amazing. Saw them live in a small-ish pub in London when they were big in Oz, but not much elsewhere. Most energy I have ever seen in a live show, bar none. Amazing.

in other news, my upcoming trip to the UK is likely to be my last for quite some time.

so do get in touch with our sales team if you'd like to have me give a talk in-person in London first two weeks of Oct, before rules shift from you *may* let me use the loo, to you *must not* let me use the loo.

Nothing Wes said is new, he just gave an incoherent interview

The UKSC ruling happened in April.

EHRC Interim Guidance came soon after.

Official EHRC guidance has been finalised and sent to the government, we are not privy to what it says yet - that’ll be sometime before the end of the year.

Yup. Nothing odd going on here at all. Gah.
Reddit screencap from r/AMA. I'm a college-educated Black man who drove from Vermont to Florida this summer with my Asian girlfriend. We were pulled over 18 times in 4 days. Ask Me Anything. After telling a few coworkers about this when I returned to work, one of them (a true Reddit head) suggested I do an AMA. So hi Reddit, nice to meet you. So I live in New England, work a white-collar job, and fall into what most would call "upper middle class." This past August, I decided to use my summer vacation to visit family in Fort Myers, Florida. Since I'd never done a true long road trip before (my longest drives were maybe 5-7 hours), my girlfriend and I thought it would be fun to make the trip by car instead of flying. We started in Burlington, Vermont, and made our way down the East Coast. The drive was about 1,500+ miles, and we stretched it over four days. I did roughly 75% of the driving, she took the rest. Here's the part that baffled me: in just those four days, we were pulled over 18 times. Not for reckless driving or doing anything spicy. Just pulled over, again and again. Each time it was something else. So I'll give this a shot: Ask me anything.

Are you an experienced software buyer? I could use your help.

I'm working on the second edition of "Observability Engineering", and hoping to include the kind of advice an experienced principal engineer might give a staff engineer buying for the first time.

If you have strong compiler / codegen / optimization skills, this could be your next big challenge.

I know a lot of folks have moved to using newsletters and even replacing their websites with the newsletter's platform/site. But, there are still a lot of people that have websites with feeds, so those are the folks I'm appealing to.

Also, my inbox weeps daily under the heavy load.

I'm creating a genealogy feed in my newest RSS feed app, and unfortunately, many of the blogs/publications I imported from another app no longer exist. ☹️

So, if you have a genealogy or history blog or are an org/society publication with a RSS feed, please drop a link below!

Happy to reskeet, too.!

It’s been a dirty word in the US for decades. As far back as McCarthy, if not farther.

What hurts my head the most is the conflation of socialism and communism. The right equates nationalized healthcare with Soviet Russia. It’s ridiculous, but so many people don’t know better.

The fact that, in the New York City Mayors race, you can have 2 candidates as obviously corrupt and horrible as Cuomo and Adams, and still have so many folks expressing concern about a “socialist” in the race, just shows how successful the anti-socialism psy-op by the U.S. right wing has been.
