Folks using #PhanpySocialDev , there are 2 new features that need a bit of testing:
1. QR code for profiles and shortcuts settings - includes scanner (camera) too
2. Import/export accounts - the export *excludes* access tokens, so need to login again after import

PSA about food labeling in the US
We have a gluten detection service dog because many things that should be gluten free/say they’re gluten free are not actually gluten free.
Stuff gets contaminated when growing (e.g. next to wheat field), by shared equipment, in factories, from packaging, during transport and in-store.
Every US consumer should know:
1. The list of ingredients on food isn't exhaustive
2. Allergen labeling:
a) limited to just some allergens
b) manufacturers don't actually have to test
c) "certified" foods are tested—but not continuously
d) testing only works with enough contamination
Some certifications may require batch-testing, but usually they don't.
A "certified gluten free" product may e.g. contain oats which sometimes are contaminated with gluten—but as not every batch is tested it's impossible to know unless you test yourself (hence the service dog).
Even if the product is properly batch-tested, you might get a part of the product that has the allergen in it, whereas the tested part didn't.
Or the threshold was too low (our dog can detect gluten better than any available lab testing equipment; yes, dogs are amazing).
Food products also contain ingredients that do not have to be included on the label when they're "incidental" (included in an another ingredient) or if they're considered part of the manufacturing process but not of the final product (e.g. various coatings on factory equipment).
Don't need to list flavors or specific spices either. ¯\_(ツ)_/¯
As for allergens, only those responsible for ~90% of food allergies* have to be specifically declared, and they're not tested for as it's simply based on the ingredients list.
Good luck if you have other allergies.

Non-iid hypothesis testing: from classical to quantum
We study hypothesis testing (aka state certification) in the non-identically distributed setting. A recent work (Garg et al. 2023) considered the classical case, in which one is given (independent) samples from $T$ unknown probability distributions $p_1, \dots, p_T$ on $[d] = \{1, 2, \dots, d\}$, and one wishes to accept/reject the hypothesis that their average $p_{\mathrm{avg}}$ equals a known hypothesis distribution $q$. Garg et al. showed that if one has just $c = 2$ samples from each $p_i$,…

Four-year testing finds heat pumps run efficiently even in older homes
Researchers at Fraunhofer ISE have tested various types of heat pumps in existing buildings across Germany over four years, finding that the systems achieved seasonal performance factors between 2.6 and 5.4. The team also showed that PV-driven heat pumps can boost self-consumption rates, particularly when paired with battery storage.

Asteroseismic investigation of HD 140283: The Methuselah star
HD 140283 is a well-studied metal-poor subgiant and a Gaia benchmark star, often used for testing stellar models due to its proximity, brightness, and low metallicity ([Fe/H] = -2.3 dex). Here we present the first asteroseismic analysis of HD 140283, providing improved constraints on its fundamental properties. The star was observed by TESS in 20-second cadence during Sector 51. We extracted a custom light curve and performed a frequency analysis, revealing a rich spectrum of solar-like osc…

'debootstrap' is one of my favourite parts of debian - and you can use it from other distros as well! It lets you setup a debian install in a directory for use with a container/chroot/etc .
My most recent two uses are 1) Building up a new debian install on an existing machine running a different distro in an LVM LV on the running system and configoring it, ready to go on reboot 2) Installing a very old debian chroot for some testing.

Directional replicability: when can the factor of two be omitted

Directional replicability: when can the factor of two be omitted
Directional replicability addresses the question of whether an effect studied across $n$ independent studies is present with the same direction in at least $r$ of them, for $r \geq 2$. When the expected direction of the effect is not specified in advance, the state of the art recommends assessing replicability separately by combining one-sided $p$-values for both directions (left and right), and then doubling the smaller of the two resulting combined $p$-values to account for multiple testing. …

Comparing Manual and Free Automated WCAG Reviews
Automated accessibility testing tools cannot test 100% of WCAG. This position is not controversial. Other than overlay vendors, no automated tool maker makes that claim.

Enhanced Breakdown Voltage in $β$-Ga$_2$O$_3$ Schottky Barrier Diodes via Fast Neutron Irradiation and Electrothermal Annealing
This study investigates the impact of fast neutron irradiation and post-radiation electro-thermal annealing on the electrical performance of $β$-Ga$_2$O$_3$ Schottky barrier diodes. Devices irradiated with 1 MeV neutrons at a high fluence of 1E15 n/cm^2 exhibited substantial degradation, including a drastic reduction in on-current and an increase in on-resistance. Electrothermal testing, conducted through simultaneous current-voltage (J-V) measurements and thermal annealing, resulted in signif…

Worked on some more #Gentoo global #jobserver goodies today.
Firstly, Portage jobserver support patch: #PyTest jobs will also be counted towards total job count.
Again, it's not a perfect solution, but it works reasonably. The plugin still starts -n jobs as specified by the arguments, but it acquired job tokens prior to executing every test, therefore delaying actual testing until tokens are available. It doesn't seem to cause noticeable overhead either.

Stress Testing Deliberative Alignment for Anti-Scheming Training
Highly capable AI systems could secretly pursue misaligned goals -- what we call "scheming". Because a scheming AI would deliberately try to hide its misaligned goals and actions, measuring and mitigating scheming requires different strategies than are typically used in ML. We propose that assessing anti-scheming interventions requires at least (1) testing propensity to scheme on far out-of-distribution (OOD) tasks, (2) evaluating whether lack of scheming is driven by situational awareness, and…

Testing Quantum Mechanics with Quantum Computers: Qubit Information Capacity
Motivated by John Wheeler's assertion that the continuum nature of Hilbert Space conceals the information-theoretic nature of the quantum wavefunction, a specific discretisation of complex Hilbert Space is proposed, leading to the notion of qubit information capacity $N_{\mathrm{max}}$: for any $N \ge N_{\mathrm{max}}$-qubit state, there is insufficient information in the $N$ qubits to allocate even one bit to each of the $2^{N+1}-2$ degrees of freedom demanded by complex Hilbert Space and henc…

BASFuzz: Towards Robustness Evaluation of LLM-based NLP Software via Automated Fuzz Testing
Fuzzing has shown great success in evaluating the robustness of intelligent natural language processing (NLP) software. As large language model (LLM)-based NLP software is widely deployed in critical industries, existing methods still face two main challenges: 1 testing methods are insufficiently coupled with the behavioral patterns of LLM-based NLP software; 2 fuzzing capability for the testing scenario of natural language generation (NLG) generally degrades. To address these issues, we propos…

The High Field Vertical Magnet Test Facility (HFVMTF) at Fermilab is designed to test superconducting magnets up to 20 tons and 1.3 meters in diameter. Central to the facility is a double-bath superfluid helium cryostat reaching 1.8 K at 1.2 bar. Integrated with a 15 T superconducting dipole from LBNL, HFVMTF supports HTS cable testing for fusion applications. This paper presents the design and fabrication of the cryostat, with a focus on two complex components: the 2 K heat exchanger and the l…
