Submission + - The US Government Has a Microsoft Problem (archive.is) 2

echo123 writes: Microsoft has stumbled through a series of major cybersecurity failures over the past few years. Experts say the US government’s reliance on its systems means the company continues to get a free pass.

Submission + - Canadian legislators accused of using AI to produce 20,000 amendments (www.cbc.ca)

sinij writes:

The amendments are what's left of nearly 20,000 changes the Conservatives proposed to Bill C-50 last fall at a House of Commons committee. Liberals now contend the Conservatives came up with the amendments using artificial intelligence in order to gum up the government's agenda.

These amendments is a filibustering strategy, as each has to be voted on.

Submission + - New charger could double the service-life of Li-Ion batteries 1

NewtonsLaw writes: Lithium-Ion (LI) batteries are the backbone of much of our modern technology. They're in our phones, our laptops, our smartwatches and even the EVs that are increasingly appearing on our roads. One of the problems with LI technolgy however, is the very finite life of those batteries.

In the case of an EV, the battery pack represents a very significant portion of the total price you pay when buying one. Right now, the life of EV batteries is generally considered to be at least eight years, under normal use. But what if that could be doubled — simply by changing the way those batteries are charged?

This announcement by researchers in Europe indicates that the service life (ie: the number of charg/discharge cycles) of LI batteries could be as much as doubled, through the use of a pulsed current charging technology.

The standard charge method for LI cells is to deliver a constant direct current (DC) until the voltage of the cell rises to around 4.2 volts, at which time the voltage is maintained at a constant level and the charge current allowed to fall off. Once the charge current reaches a predefined minimum level, the cell is considered charged.

The new pulsed current method does not use DC but instead opts to recharge by way of intermittent pulses of current. This is not a new charging technology although it's not the norm for LI cells. Pulsed current chargers have been used on older chemistries such as nickel-cadmium in order to reduce/eliminate the formation of dendrites that would otherwise create short-circuits or significantly increase the self-discharge rate. Applying this tech to recharging LI cells seems to be a significant game-changer, if the lab results are duplicated in "the real world (TM)"

Doubling the life of your EV's battery or even your smartphone's battery is no small thing.

Submission + - When #OpenToWork is really #OpenToScam

benrothke writes: Many job seekers often change their LinkedIn status to #OpenToWork.
Scammers have capitalized on that and reach out to them with scams to trick and swindle them.
They won’t find a new job, but will lose their money in a scam.
