oori··on Vermont replacing power plants with home batteries
Many do (assuming bidirectional charger), but it’s only 3.6kW max, in most cases
oori··on Grafana Labs internal source code accessed
Quote: “ The attacker attempted to blackmail us, demanding payment to prevent the release of our codebase. ...we’ve determined the appropriate path forward is to not pay the ransom.”
oori··on KORG phase8 – Acoustic Synthesizer
Reminds me of the original Korg Wavedrum from the 90s, which was by far the best e-drum ever, you can lightly scratch it or hit it with a strong stick, endless tone and amplitude possibilities.
oori··on Xleak – terminal Excel viewer with an interactive TUI
Features full-text search, formula display, lazy loading for large files, clipboard support, and export to CSV/JSON
oori··on How big a solar battery do I need to store all my home's electricity?
The ratio between storage capacity and production power seems way too low, unless your daily consumption is ~10-15kWh and your batteries are over spec for harsh winter days (and then you’d need couple of sun days to recover). Are you sure about these numbers?

oori··on SMTP Smuggling – Spoofing Emails Worldwide
Strange they didn’t wait with this announcement a week or two, to allow proper holiday to fellow developers.

From postfix - “Days before a 10+ day holiday break and associated production change freeze, SEC Consult has published an email spoofing attack that involves a composition of email services with specific differences in the way they handle line endings other than <CR><LF>.

Unfortunately, criticial information provided by the researcher was not passed on to Postfix maintainers before publication of the attack, otherwise we would certainly have convinced SEC Consult to change their time schedule until after people had a chance to update their Postfix systems. ” - https://www.postfix.org/smtp-smuggling.html

oori··on Affordable device will let anyone connect their brain to a computer
I have a bunch of devices (off the shelf, and custom built) and built neuro-experiences used by thousands of people.

Neurosky is by far the worst. It’s nearly random. From the low cost devices, Muse (1 or 2) is by far the best.

UX, wearability, comfort, electric signal.

oori··on AI Art: Fashion Show for Seniors
Nigerian AI artist reimagining a stylish old age - "At first glance, his images look like they were snapped on the edge of a fashion runway, but these models are not actually real people."
oori··on Tobii Pro Glasses 3
Proof please?!

“The license you accept only applies to their software, not to their hardware.”

As far as I know, their EULA has three groups: gamers, commercial, research. You can buy a 3000€ research license that simply allows you to collect the eye tracking data on the basic 250€ devices…

oori··on Ask HN: Why isn‘t „solar hydrogen“ a thing for seasonal energy storage?
1. Storage and pipes: highly regulated, you need local permits to store and use, and those are usually capacity-limited. And after that - the pipeline and various gas leak protection mechanisms are expensive.

2. Electrolyzer efficiencies are ~50%. (one way). Some new companies claim higher numbers, but it’s still 2-5 years away.

3. First viable use cases are micro-grids (towers, neighborhood, hospital, ..), rather than single homes

oori··on The US Government May Have Wasted $22B on HoloLens
“ Pentagon may have wasted more than $22 billion on Microsoft’s HoloLens by failing to ask if the soldiers who would be theoretically responsible for deploying the hardware actually wanted to use it or perceived any benefit from doing so”
oori··on Facebook drops funding for interface that reads the brain
“ The company says it now plans to open-source the software it developed for brain decoding and also provide access to prototype devices, so other researchers can benefit from its work”

Anyone found this repo ? I would love to see some of their pipeline’s parameters. They ‘should’ have a fine-tuned processing pipeline that’s interesting for different kind of bio-signal sensors.

oori··on No to Racism: Modbus Organization Replaces Master-Slave with Client-Server [pdf]
...Board Chair Todd Snide commented, "The time is overdue for these words to be removed. The terms are unnecessary and insensitive to the people who experience racism in this country and around the world. We urge our member companies and all those who use the Modbus protocol to take similar action to rid their documentation and communications of these terms."

oori··on Could wooden building be a solution to climate change?
Very interesting article. Quote:

Many pine trees in managed forests, such as the European spruce, take roughly 80 years to reach maturity, being net absorbers of carbon during those years of growth – but once they reach maturity, they shed roughly as much carbon through the decomposition of needles and fallen branches as they absorb. As was the case in Austria in the 1990s, plummeting demand for paper and wood saw huge swathes of managed forests globally fall into disuse. Rather than return to pristine wilderness, these monocrops cover forest floors in acidic pine needles and dead branches. Canada's great forests for example have actually emitted more carbon than they absorb since 2001, thanks to mature trees no longer being actively felled. Arguably, the best form of carbon sequestration is to chop down trees: to restore our sustainable, managed forests, and use the resulting wood as a building material. Managed forests certified by the Forest Stewardship Council (FSC) typically plant two to three trees for every tree felled – meaning the more demand there is for wood, the greater the growth in both forest cover and CO2-hungry young trees.

oori··on 3d print: turns smartphone into fully operational microscope
Note 1: These files have only been tested with an iPhone 6s. Other models of mobile phones may require alterations to the clip geometry. To do this, edit the solidworks file appropriately for your specific phone model.

Note 2: Depending on their 3D printer, users may need to alter the scaling for these models to fit properly over an iPhone 6s. We have encountered that the scaling may need to be adjusted by up to 10% from a FORM 1 3D printer to a FORM 2 3D printer. This can be done directly in the .form file, or using the editable solidworks file.

oori··on Vast solar power plant at the Moroccan desert
"Hundreds of curved mirrors, each as big as a bus, are ranked in rows covering 1,400,000 sq m (15m sq ft) of desert, an area the size of 200 football fields."

"The plant keeps generating energy after sunset, when electricity demands peak. Some of the day’s energy is stored in reservoirs of superhot molten salts made of sodium and potassium nitrates, which keeps production going for up to three hours. In the next phase of the plant, production will continue for up to eight hours after sunset."
