Are Depth-2 Regular Expressions Hard to Intersect?
We study the basic regular expression intersection testing problem, which asks to determine whether the intersection of the languages of two regular expressions is nonempty. A textbook solution to this problem is to construct the nondeterministic finite automaton that accepts the language of both expressions. This procedure results in a $Θ(mn)$ running time, where $m$ and $n$ are the sizes of the two expressions, respectively. Following the approach of Backurs and Indyk [FOCS'16] and Bringmann…

Now you've done it. You've hurt my cuddle bunny's feelings.

KI-generierte Zusammenfassung von Google führt zu Gerüchten:
Vor knapp einer Woche war unser Leitungswasser wegen einer mikrobiologischen Verschmutzung nicht trinkbar. Die Bevölkerung wurde dazu aufgerufen, das Wasser abzukochen.
Nun gehen in lokalen Chats Screenshots rum, die behaupten, es wären PFAS gewesen. Die Google KI-Zusammenfassung spinnt das wohl aus einem Zeitungsartikel zusammen, in dem nebenbei über vergangene PFAS-Verunreinigungen berichtet wurde

#PennedPossibilities 692 — Share a song that either describes your current feelings about your story or your MC in general.
The first time I heard this song, I immediately thought of my poor MC. The lyrics felt honest, and fit the dark hour of his soul.
“Cause out here in the darkness,
and out of the light,
if you get to me too late,
just know that I tried”

Investigating MAXI J1752$-$457 with NuSTAR in the aftermath of a superburst
We present two NuSTAR observations of the X-ray transient, MAXI J1752$-$457, following a superburst which was observed by MAXI/GSC in November, 2024. NuSTAR follow-up confirmed that MAXI J1752$-$457 is coincident with the previously observed Einstein Probe source, EP240809a. We performed a spectral analysis of the source during both NuSTAR observations, and we confirm that the hard X-ray spectra are consistent with the inclusion of a spherical blackbody component. At about 79 hours after the on…

Brian Schottenheimer doesn't care to hurt feelings, only championships https://www.si.com/nfl/cowboys/news/dallas-cowboys-brian-schottenheimer-doesnt-care-hurt-feelings-only-championships

I need your help. It's surprisingly hard to find a PC game (or port/emulation) that ticks the following boxes:
- generally easy, or with easy difficulty setting
- mostly linear, not open world
- story-driven
- ideally, controller support
You know what I mean? I'm looking for something relaxing for when my brain is exhausted where I don't have to make too many decisions.

There was once a machine that told you "you want this" and "this is good." It said, "there can be no better system and it's foolish to try to build one." That machine has long since failed to function. Now you choke on fumes as it is consumed by the wild flames of an abandoned cause.
That machine could not possibly work anymore because the evidence of it's falsehood has become too overwhelming.
No, only abject terror now can keep you from plotting your escape, from creating an alternative. No, the illusion has long since broken. All that's left now is triggering fight, flight, freeze as hard as possible. Most will be paralyzed, and those who fight can be used as an excuse to escalate the terror.
These are the final stages of a dying sun, expanding and consuming it's children before the final supernova.
There is no longer a stable system, no longer a system with a future. All that remains is the spectacle that hopes to distract you long enough that you too can be consumed, that it may sustain itself a few moments longer.

Oh, why aren't you a cat person? I'll tell you: my brother was attacked, bitten and scratched on both hands this week by a feral cat in his kitchen and had to go for surgery to get the infected parts out. And he did all this to protect his own cat. I'll be watching those 'cute' cat videos with a different kind of feeling. I've heard they taste similar to rabbits.
