Our journey with Swift thus far - some notes and reflections
Hello! Background Our team is quietly working on developing a new electronic trading system using Swift on macOS and Linux, building on our experience from two previous projects that have been done in C, Objective-C, C++, Java, C# and even for a while, homegrown DSL. All running on multiple OS:s at various points; NeXTSTEP, OpenStep, Windows NT, HP-UX, Solaris, Linux. These past projects have been fairly sizeable, with over 25 million lines of code and several hundred components between them o…

After 11 months of being here, I decided to do a very small reflection.
When I first arrived, I didn't have any expectations or goals I'd like to achieve. Matter of fact, the main reason I left Twitter is because of all the bots that followed me and how I almost never got any real interaction.
Over time, things got a little rocky here and it seemed as though, personally, I wasn't going to be enjoying it any further at that time and contemplating shutting the instance down completely and just "disappearing".
However, several months on from that, I'm VERY glad I didn't. I like it here and I like having my "own little space" where nobody can tell me what I can and cannot discuss nor what I can and cannot see.
Something I've just recently realized though, is how important a good bit of you have become to me, personally and my Fedi experience would be very lacking without some of you here. What I didn't expect, was getting that same sentiment back when I discussed it with those few of you. I really appreciate knowing that for some of you, I have been consistently a "good" addition to your timelines and everyday online life.
Those types of comments and feelings they give me, keep me here and sane on those wilder days. To each and every one of you that have followed me for so long, through all the craziness, slight drama, wild opinions, and more, THANK YOU.
If I hadn't been almost universally accepted with such open arms and returned the same energy I try to put out, then I doubt I would still be here to this day.
I'm 11 months in and I think I'm ready to "give back" to those few folks that I consider friends and am on the cusps of creating something new and hopefully something good for Fedi as a whole.
I'm going to keep it very limited for specific reasons I'll lay out later. But, this is new ground for me and I have to figure some things out and hopefully not make too many missteps and learn some things along the way.
Thank you Fedi. I wouldn't be who I am right now, without you.

Working on some new presentation abstracts.
One topic I'm particularly interested in is versioning and how to evaluate a project with healthy versioning vs projects that have versioning that will make your life hell.
So, this talk would go over projects where they intentionally stay below 1.0.0 for 10 years, have breaking or license changes in minor or patch versions. and un-versioned documentation. Stuff like that.
What term fits best?

Soooo....I'm doing a thing...🤭😏
As a lot of you know, Tooters shut down recently and the way it was handled in the end is regrettable.
However, I felt for longest time while it was up, that it was consistently one of the BEST run instances on Fedi with how they protected their users from some of the insanity that happens here.
That being said, with Tooters being gone, it leaves a bit of a hole in my Fedi heart and I know a lot of others as well.
So, I'm creating a new, very limited for now, politically-light (as little politics as possible locally), AI friendly (AI art welcome), Sharkey instance for some folks within my circle that I've grown to consider my friends.
The Social Zone is meant to be a place to escape the very political society we currently all live in and just be social with one another about our hobbies, interests, and day to day lives.
I'm still working out all the details but when I launch it, it's going to be invite only because I'm new to something like this and I want to get it right. Especially because those I will invite are people that are close to me and I don't want to disappoint them.
Depending on how things go for the next few months, including if I can even get this thing started correctly, I MIGHT be open to allowing more members in, down the line.
But, this is just getting started. I registered the domain yesterday and just started researching Sharkey today and how hard it would be to spin something up. Then, of course, there's configuration settings and administration with Sharkey that I have to familiarize myself with.
All in all, I'm very nervous, but excited that I decided to take this next step in my Fedi adventure and hope to eventually "give back" to the entire community, the same positive energy that you've all given me over the past wonderful year of being on this amazing platform.
Please do not ask for invites. I will not be handing them out anytime soon. I've already asked about 5 of you along with some IRL folks and I feel I would like some time to get this right for them first.
Thanks for reading. I hope you understand why I'm choosing to do this and hope you're as excited as me to see where things can go and understand why I feel it's important to have these types of "politically-light" spaces so people can escape such topics from time to time.
Keep on keeping on, Fedi. The future is bright and I'm ready to learn along with you. More info about TheSocial.Zone coming soon!
Your friend,

Dilators and the reverse mathematics zoo
A predilator is a particularly uniform transformation of linear orders. We have a dilator when the transformation preserves well-foundedness. Over the theory $\mathsf{ACA}_0$ from reverse mathematics, any $Π^1_2$-formula is equivalent to the statement that some predilator is a dilator. We show how this completeness result breaks down without arithmetical comprehension: over $\mathsf{RCA}_0+\mathsf{PA}$, the statements from a large part of the reverse mathematics zoo are not equivalent to some …

Some density results for hyperkähler manifolds
Lagrangian fibrations of hyperkähler manifolds are induced by semi-ample line bundles which are isotropic with respect to the Beauville-Bogomolov-Fujiki form. For a non-isotrivial family of hyperkähler manifolds over a complex manifold $S$ of positive dimension, we prove that the set of points in $S$, for which there is an isotropic class in the Picard lattice of the corresponding hyperkähler manifold represented as a fiber over that point, is analytically dense in $S$.

Reservoir Sampling over Joins
Sampling over joins is a fundamental task in large-scale data analytics. Instead of computing the full join results, which could be massive, a uniform sample of the join results would suffice for many purposes, such as answering analytical queries or training machine learning models. In this paper, we study the problem of how to maintain a random sample over joins while the tuples are streaming in. Without the join, this problem can be solved by some simple and classical reservoir sampling algo…

Furthermore, for $q=7^k$, $m \geq 7$ and rational functions wi…

Our witnesses are applicable to both universal (all runs) and existential (some run) settings. We then consider LTL formulas in which atomic propositions can be polynomial constraints and turn our focus to polynomial arithmetic programs, i.e. programs in which…

Additionally, we prove that the Auslander-Reiten conjecture holds true for all finitely generated modules $M$ over a Noet…

Happy Appomattox Day! Frederick Douglass has some strong words for remembering what the victory over the Confederacy meant.
We are sometimes asked, in the name of patriotism, to forget the merits of this fearful struggle, and to remember with equal admiration those who struck at the nation's life and those who struck to save it, those who fought for slavery and those who fought for liberty and justice.
I am no minister of malice. I would not strike the fallen. I would not repel the repentant; but may my right hand forget her cunning and my tongue cleave to the roof of my mouth, if I forget the difference between the parties to that terrible, protracted, and bloody conflict.
...But we are not here to applaud manly courage, save as it has been displayed in a noble cause. We must never forget that victory to the rebellion meant death to the Republic."

Quasinormal modes and bound states of massive scalar fields in wormhole spacetimes
In this work we explore the propagation of massive scalar fields on some wormhole backgrounds. On one side, we consider the Bronnikov-Ellis wormhole solution and wormhole geometries with a non-constant redshift function by introducing a gravitational mass $M$, which goes over into the Bronnikov-Ellis wormhole when the gravitational mass parameter vanishes. We employ the continued fraction method to calculate accurately the quasinormal frequencies of massive scalar fields, particularly focusing …

Torsion subgroups of Whitehead groups of graded division algebras
In this paper, we study the torsion subgroup, which is denoted by ${\rm TK}_1(E)$, of the Whitehead group $E^*/[E^*,E^*]$ of a graded division algebra $E$ which is finite dimensional over its center. In particular, we provide formulas for ${\rm TK}_1(E)$ in some special cases such as when $E$ is unramified, totally ramified or semiramified. Using the formulas, we are able to compute the group ${\rm TK}_1(D)$ of a valued division ring $D$, which is finite dimensional over a henselian center.

Parameterized Complexity of Submodular Minimization under Uncertainty
This paper studies the computational complexity of a robust variant of a two-stage submodular minimization problem that we call Robust Submodular Minimizer. In this problem, we are given $k$ submodular functions $f_1,\dots,f_k$ over a set family $2^V$, which represent $k$ possible scenarios in the future when we will need to find an optimal solution for one of these scenarios, i.e., a minimizer for one of the functions. The present task is to find a set $X \subseteq V$ that is close to some opt…

Israel-Hamas war: Children begin to die of hunger in Gaza
It’s not just Israeli bombs that have killed children in war-ravaged Gaza. Now some are dying of hunger too. Officials have for months warned over the risk of famine in Gaza under Israel’s bombardment, offensives and siege. Hunger is most acute in the north, where at least 20 people — almost all children — have died from malnutrition and dehydration. That's according to Gaza's Health Ministry. But also in the south, where access to aid is more regular, particularly vulnerable children a…

Information divergences to parametrize astrophysical uncertainties in dark matter direct detection
Astrophysical uncertainties in dark matter direct detection experiments are typically addressed by parametrizing the velocity distribution in terms of a few uncertain parameters that vary around some central values. Here we propose a method to optimize over all velocity distributions lying within a given distance measure from a central distribution. We discretize the dark matter velocity distribution as a superposition of streams, and use a variety of information divergences to parametrize its …

G-semisimple algebras
Let $Λ$ be an Artin algebra and ${\mathsf{mod}}\mbox{-} ({\underline{\mathsf{Gprj}}}\mbox{-}Λ)$ the category of finitely presented functors over the stable category ${\underline{\mathsf{Gprj}}}\mbox{-}Λ$ of finitely generated Gorenstein projective $Λ$-modules. This paper deals with those algebras $Λ$ in which ${\mathsf{mod}}\mbox{-} ({\underline{\mathsf{Gprj}}}\mbox{-}Λ)$ is a semisimple abelian category, and we call G-semisimple algebras. We study some basic properties of such algebras. …

A two-state solution? How about no states instead. "There is just no escaping the absolute inadequacy of statism and nationalism for resolving questions of social justice. Here the Anarchist tradition has an old proposal that looks much more promising. The Anarchists thought that nation-states should be replaced by federations of regional assemblies."

Solving Complex Multi-UAV Mission Planning Problems using Multi-objective Genetic Algorithms
Due to recent booming of UAVs technologies, these are being used in many fields involving complex tasks. Some of them involve a high risk to the vehicle driver, such as fire monitoring and rescue tasks, which make UAVs excellent for avoiding human risks. Mission Planning for UAVs is the process of planning the locations and actions (loading/dropping a load, taking videos/pictures, acquiring information) for the vehicles, typically over a time period. These vehicles are controlled from Ground Co…

Correlated vs. Uncorrelated Randomness in Adversarial Congestion Team Games
We consider team zero-sum network congestion games with $n$ agents playing against $k$ interceptors over a graph $G$. The agents aim to minimize their collective cost of sending traffic over paths in $G$, which is an aggregation of edge costs, while the interceptors aim to maximize the collective cost by increasing some of these edge costs. To evade the interceptors, the agents will usually use randomized strategies. We consider two cases, the correlated case when agents have access to a shared…

Sound and Complete Witnesses for Template-based Verification of LTL Properties on Polynomial Programs
We study the classical problem of verifying programs with respect to formal specifications given in the linear temporal logic (LTL). We first present novel \emph{sound and complete} witnesses for LTL verification over imperative programs. Our witnesses are applicable to both universal (all runs) and existential (some run) settings. We then consider LTL formulas in which atomic propositions can be polynomial constraints and turn our focus to polynomial arithmetic programs, i.e. programs in which…

Generation and decidability for periodic l-pregroups
In [11] it is shown that the variety $\mathsf{DLP}$ of distributive l-pregroups is generated by a single algebra, the functional algebra $\mathbf{F}(Z)$ over the integers. Here, we show that $\mathsf{DLP}$ is equal to the join of its subvarieties $\mathsf{LPn}$, for $n\in\mathbb{Z}$, consisting of n-periodic l-pregroups. We also prove that every algebra in $\mathsf{LPn}$ embeds into the subalgebra $\mathbf{F}_n(Ω)$ of n-periodic elements of $\mathbf{F}(Ω)$, for some integral chain $Ω$; we us…

Higher Chow groups and not necessarily admissible cycles
We construct some analog of cubical Bloch's higher Chow groups. Instead of considering cycles in $X\times\mathbb A^n$ we consider varieties $Y$ over $X$ together with a distinguished element in the $n$-th exterior power of the multiplicative group of the field of fraction on $Y$. This definition allows us to make sense of a cycle in $X\times\mathbb A^n$ intersecting faces improperly as an element in this complex. We prove that this complex is well-defined and study its basic properties: flat …

The Iwasawa $μ$-invariant of certain elliptic curves of analytic rank zero
This paper is about the Iwasawa theory of elliptic curves over the cyclotomic $\mathbb{Z}_p$-extension $\mathbb{Q}^{\text{cyc}}$ of $\mathbb{Q}$. We discuss a deep conjecture of Greenberg that if $E/\mathbb{Q}$ is an elliptic curve with good ordinary reduction at $p$, and $E[p]$ is irreducible as a Galois module, then the Selmer group of $E$ over $\mathbb{Q}^{\text{cyc}}$ has $μ$-invariant zero. We prove new cases of Greenberg's conjecture for some elliptic curves of analytic rank $0$. The pro…

Sometimes I read an article twice, this was such an article, explains why also in 2024 we don't fully understand LLMs , they are not "just statistics" as some argue, simply because some aspects with regard to generalisation and over fitting seem to work differently. Working on those models is still "more alchemy then chemistry".

Large language models can do jaw-dropping things. But nobody knows exactly why.
And that's a problem. Figuring it out is one of the biggest scientific puzzles of our time and a crucial step towards controlling more powerful future models.

On pseudoeffective cones of projective bundles and volume function
In this article, we compute the pseudo-effective cones of various projective bundles $\mathbb{P}_X(E)$ over higher dimensional varieties $X$ under some assumptions on $X$ as well as on the vector bundle $E$. We also compute the volume function on fibre product $\mathbb{P}(E)\times_C\mathbb{P}(F)$ of two projective bundles over a smooth irreducible complex projective curve $C$. In particular, we show that the volume function on the fiber product of two ruled surfaces is of polynomial type.
