Asana has the same problem. Really frustrating.

Probably trace_log (we had a similar experience), but you'll only notice with limited storage space, and a regular keen eye on how your database fills up.

New comment by mrngm in ".de TLD offline due to DNSSEC?"

mrngm — Tue, 05 May 2026 21:23:29 +0000

Unfortunately, even domains that did not have DNSSEC enabled earlier today are affected.

We observed issues on a non-DNSSEC .de domain at 19:45Z and confirmed around 20:12Z it wasn't just us, but also more high profile domain names.

New comment by mrngm in "Queueing Requests Queues Your Capacity Problems, Too"

mrngm — Fri, 03 Apr 2026 20:01:39 +0000

If you have individual request logs with timing infomation, you could construct that afterwards. It does take some effort to have an effective way of displaying these metrics. Where would you put an individual request that took 532ms and started at t=34.682s? Would you align all requests that started in the 34th second at t=34s, or look at completion time (ie within t=35s)?

Would you rather see "number of requests started at this ms" (you seem to suggest this), or is something else more interesting?

I think a sort of Gantt chart that plots duration of requests as well as starting time within the time span (e.g. a second or more) might be very informative. Each individual request on a different position on the Y axis, time on the X axis. Perhaps you have some bound on requests in flight, that could be the height of the Y axis, so you can easily see calm or busy periods.

At least our observability stack doesn't show this level of detail, but it would be very interesting to have it. (We do have calculated heatmaps based on maximum request time in Grafana, which is at least better than plots of average request times)

That reminds me of this talk[0] by Gil Tene called "How NOT to Measure Latency" at the Strangeloop conference in 2015 (or read this blog post[1] that contains the most important points).

[2020], and written for IOCCC: The International Obfuscated C Code Contest.

This was awarded "Best of Show - abuse of libc" at the time[0]. See also the judges' remarks[1]:

This program consists of a single printf(3) statement wrapped in a while loop. You would not think that this would amount to much, but you would be very, very wrong. A clue to what is happening and how this works is encoded in the ASCII art of the program source.

New comment by mrngm in "Ask HN: Notification Overload"

mrngm — Tue, 27 Jan 2026 19:54:41 +0000

Agree. I'll catch up on group chats that do not require immediate attention when it suits me, not when the stream of messages happens to arrive.

As for OP: read up on alert fatigue; if a notification isn't directly actionable, you shouldn't even see it!

The pull model for information is more durable for humans than the push model. Try RSS for news/blogs, take some time (preferably offline) each week to prepare for the important events in the upcoming week(s), write them down on something you pass by every day (such as a whiteboard near your front door).

This.

It seems your project is at a really early stage. Almost none of the links on the page work, which is too bad, because it could have provided more background information on your goals and wishes. The only thing that seems to work is login through Google, which is a bit much for a demo site.

What's going to be the edge above the already excellent https://bgp.tools ?
