Tras el éxito de Different Class y la salida del guitarrista Russel Senior de la banda, en 1998 publican This is Hardcore, un muy buen disco, pero que no tuvo tanto éxito comercial como el anterior. Con él termina la gran trilogía de éxitos de Pulp.
«Help the Aged» fue el primer single del šlbum.

The Coup, "Piss on Your Grave" (1998)

"Twelve years after “As We May Think”, and simultaneous with the developments of the IBM 1401 and FORTRAN, copies of “Datamation” started popping up on selected newsstands. This magazine was the godfather of all programming magazines, and held its crown for 41 years (quite a few ages in computer time!), until being phased out as an online magazine in February 1998."

Fun post: Dave Farquhar, History of #overclocking
#Celeron:
> In 1998, Intel released the Celeron to compete with cheap CPUs from AMD and Cyrix. To make it, they took all of the Level 2 cache off a Pentium II, clocked it at 266 or 300 MHz, and sold it at an AMD-like price. But due to the lack of L2 cache, it was slower than a previous-generation Pentium running at 233 MHz, let alone an AMD or Cyrix chip running at 266 or 300 MHz.
>
> But the L2 cache was the Pentium II’s limiting factor in overclocking. So a 266 MHz Celeron ran happily at 400 MHz, or potentially even 450 MHz, the same speed as the fastest Pentium II at the time. It was slower than a Pentium II at the same speed, but it worked well for 3D gaming.

> But the only people who bought those Celerons were overclockers and people who didn’t know anything about computers. […]

1998 in #Canada is going to be a good year.

Crossing from Pembroke #Wales to Rosslare #Ireland, I just saw dozens of #puffins flying close to the Ferry.
When we first stayed in #Pembrokeshire in 1998, we happened to stay near Martin's Haven one night and simply got a place on a boat to #Skomer Island when arriving at the harbour. I never again saw so many puffins so close.

More on the corner-vector construction for spherical designs
This paper explores a full generalization of the classical corner-vector method for constructing weighted spherical designs, which we call the {\it generalized corner-vector method}. First we establish a uniform upper bound for the degree of designs obtained from the proposed method. Our proof is a hybrid argument that employs techniques in analysis and combinatorics, especially a famous result by Xu(1998) on the interrelation between spherical designs and simplical designs, and the cross-ratio…

On the Unimodular Isomorphism Problem of Convex Lattice Polytopes
This paper studies the \emph{unimodular isomorphism problem} (UIP) of convex lattice polytopes: given two convex lattice polytopes $P$ and $P'$, decide whether there exists a unimodular affine transformation mapping $P$ to $P'$. We show that UIP is graph isomorphism hard, while the polytope congruence problem and the combinatorial polytope isomorphism problem (Akutsu, 1998; Kaibel, Schwartz, 2003) were shown to be graph isomorphism complete, and both the lattice isomorphism problem ( $\mathrm{S…

Distinguishing Filling Invariants Associated to Conjugacy in Groups
Brick and Corson introduced annular Dehn functions in 1998 to quantify the conjugacy problem for finitely generated groups and gave the fundamental relationships between it, the Dehn function, and the conjugator length function. We furnish the theory with diverse examples groups. In particular, we show that these three invariants are independent -- no two of the three functions determine the other.

Discovery of a 0.8-mHz quasi-periodic oscillations in the transient X-ray pulsar SXP31.0 and associated timing transitions
We present the first broad-band spectral and timing study of the Be/X-ray pulsar XTE J0111.2$-$7317 (SXP31.0) during its first major outburst since its discovery in 1998. This giant Type II outburst, observed in April-June 2025, marks the source's return to activity after nearly three decades of quiescence. Utilizing our NuSTAR observations together with Swift/XRT and SRG/ART-XC ones, we trace the evolution of the outburst to a peak bolometric luminosity of $L_{\rm bol} = 3.6 \times 10^{38}$ er…

On finite factorization Puiseux algebras
An integral domain $D$ is called a finite factorization domain (FFD) if every nonzero nonunit element of $D$ has only finitely many non-associate divisors. In 1998, for an integral domain $D$ and a cancellative torsion-free monoid $S$ such that each nonzero element of its quotient group is of type $(0,0, \ldots)$, Kim proved that the monoid domain $D[S]$ is an FFD if and only if $D$ is an FFD and $S$ is an FFM. However, it is still open whether a monoid algebra $K[S]$ is an FFD provided that $S…

Towards a TeV blazar sequence and its physical interpretation
Blazars, a highly energetic subclass of jetted active galactic nuclei, show a broad band spectral energy distribution (SED) with two bumps, resulting from non-thermal jet emission. In 1998, an anticorrelation between the SED luminosity and the peaks frequency was found, later confirmed in 2017, called the blazar sequence. Its origin is still unclear. This work is part of a broader effort aiming at giving a physical interpretation to the blazar sequence, by modeling the sources emission in a Syn…

Existence of infinitely many homotopy classes from $\mathbb S^3$ to $\mathbb S^2$ having a minimimzing $W^{s,\frac 3s}$-harmonic map

Existence of infinitely many homotopy classes from $\mathbb S^3$ to $\mathbb S^2$ having a minimimzing $W^{s,\frac 3s}$-harmonic map
In 1998 T. Rivière proved that there exist infinitely many homotopy classes of $π_3(\mathbb S^2)$ having a minimizing 3-harmonic map. This result is especially surprising taking into account that in $π_3(\mathbb S^3)$ there are only three homotopy classes (corresponding to the degrees $\{-1,0,1\}$) in which a minimizer exists. We extend this theorem in the framework of fractional harmonic maps and prove that for $s\in(0,1)$ there exist infinitely many homotopy classes of $π_{3}(\mathbb S^…

Divisibility of Griesmer Codes
In this paper, we consider Griesmer codes, namely those linear codes meeting the Griesmer bound. Let $C$ be an $[n,k,d]_q$ Griesmer code with $q=p^f$, where $p$ is a prime and $f\ge1$ is an integer. In 1998, Ward proved that for $q=p$, if $p^e|d$, then $p^e|\mathrm{wt}(c)$ for all $c\in C$. In this paper, we show that if $q^e|d$, then $C$ has a basis consisting of $k$ codewords such that the first $\min\left\{e+1,k\right\}$ of them span a Griesmer subcode with constant weight $d$…
