🗣️ Announcing Python-Blosc2 3.8.0 🚀

A step closer to compliance with the array-api standard: data-apis.org/array-api!
This is an effort across all array-based libraries so that your code works (e.g. for both blosc2 and NumPy) by simply changing the import statement below!

Highlights:
✅ C-Blosc2 updated to latest 2.21.2
✅ Incorporate isnan, isfinite, isinf
✅ Better indexing coverage
✅ linspace and arange functions more numerically stable
✅ Improved array-api compliance

What have been peep's experiences with building RAID arrays with 16TB, 20TB, etc. hard drives?

Too big and slow to pivot when a drive breaks? Lower reliability per spindle compared to smaller units? No differences of note?

Context: I have multiple 6 disk draid2 configs with 8TB spindles. The drives are aging out and could use an excuse to reduce the number of spindles (less heat, noise, power, weight). Thinking about 3-4 way raidz[1|2] — or maybe something different.

Opinions and comments appreciated.

More about #StarIsland -- in addition to a #Solar array, they also have #wastewater treatment!

Creating the Future of Wastewater

April 25, 2018

"Plans for the new wastewater treatment/reclamation system on Star Island are moving forward and our groundbreaking project should be operational next year! Financing approval for the project was assured last July with the signing of formal documents for a low-interest loan from the State of New Hampshire Department of Environmental Services (DES) under the EPA’s Clean Water State Revolving Fund. This program has until recently provided money only to municipalities for wastewater improvements. Recent changes in the program guidelines have opened the program to non-profit organizations. Star Island was the first non-profit in the state to qualify for a wastewater loan, which has a low fixed interest rate and a term of twenty years.

"In addition to finding a reliable system that can address our seasonal occupancy fluctuation and effectively manage the high nutrient content of the island waste stream, engineers were also asked to recommend an approach which reduces electricity demand, and can allow recycling of treated wastewater for uses such as toilet flushing and irrigation.

"The first recommendation in the Underwood Report is to install an expanded grease trap system that can remove more waste materials from the kitchen flow before they hit the treatment plant. This system will be installed this spring. A series of large plastic chambers will contain the wastewater from the kitchen, slowing it down long enough to cool. This allows suspended fats, oils and grease to be captured for later disposal before it reaches the waste treatment plant. Such removal is essential to efficient and reliable operation of any system.

"The report goes on to evaluate ten different treatment system options on the basis of cost, feasibility, visual impact, ease of operation, quality of treated effluent, energy consumption and other factors. Underwood recommends a system called #Amphidrome, in technical terms a 'submerged attached growth biologically active filter (#BAF).' These systems are manufactured in New England and have been successfully deployed in hospitals, resorts, schools, office parks and similar developments with large wastewater demands not serviced by public sewers. The system, which fits entirely within the existing waste treatment tanks, relies on bacteria and filtration to process up to 17,000 gallons of island wastewater per day, using only 10% of the energy of our current system!

"The final product, after disinfection similar to that used in our drinking water system, is expected to be non-potable re-use. No longer simply wastewater for ocean discharge, this reclaimed resource will ultimately be used to flush island toilets and for lawn irrigation. Star Island is working with DES to help write the rules for the use of recycled wastewater in what is recognized as an important pilot project in New Hampshire that will have statewide benefits for waste treatment and water conservation efforts."

Georgia State University’s Center for High Angular Resolution Astronomy (CHARA) Array is marking the 20th anniversary of its first scientific results, published in July 2005: https://news.gsu.edu/2025/07/21/chara-array-enters-third-decade-of-celestial-discovery/ - one paper revealed new astronomical insights about the massive star Regulus, and the other detailed how the #CHARA interferometer enabled the discoveries.
