My latest @newscientist.com cartoon
Panel 1: a large robot (composed of AI servers, network switches, storage arrays, and power distribution units) and a human are talking.

Professor "You don't want to destroy humanity do you, lLLM-A-9300x?"

Robot "Haha. What a silly question, Professor. I have no desires or feelings of my own whatsoever."

Professor (relieved)"Oh good." 

Panel 2: they walk on. The robot continues  "I am merely a tool of the company that created me. And that company, being composed of humans, will naturally have humanity's best interests at heart."

Panel 3: The professor is conspicuously quiet.
"Right?" says the Robot.
…
More silence

"Professor?"

Driving safety, Motorola's 2008 version 🫪
Photo of a Motorola phone manual page from 2008: Smart Practices While Driving

Drive Safe, Call Smart (SM)

Check the laws and regulations on the use of mobile devices and their accessories in the areas where you drive. Always obey them. The use of these devices may be prohibited or restricted in certain areas. Go to www.motorola.com/callsmart for more information.

Your mobile device lets you communicate by voice and data-almost anywhere, anytime, wherever wireless service is available and safe conditions allow. When driving a car, driving is your first responsibility. If you choose to use your mobile device while driving, remember the following tips:

Get to know your Motorola mobile device and its features such as speed dial and redial. If available, these features help you to place your call without taking your attention off the road.

When available, use a handsfree device. If possible, add an additional layer of convenience to your mobile device with one of the many Motorola Original handsfree accessories available today.

Driving Safety, page 9Next page of that 2008 phone manual:

Position your mobile device within easy reach. Be able to access your mobile device without removing your eyes from the road. If you receive an incoming call at an inconvenient time, if possible, let your voice mail answer it for you.

Let the person you are speaking with know you are driving; if necessary, suspend the call in heavy traffic or hazardous weather conditions. Rain, sleet, snow, ice, and even heavy traffic can be hazardous.

Do not take notes or look up phone numbers while driving. Jotting down a "to do" list or going through your address book takes attention away from your primary responsibility-driving safely.

Dial sensibly and assess the traffic; if possible, place calls when your car is not moving or before pulling into traffic. If you must make a call while moving, dial only a few numbers, check the road and your mirrors, then continue.

Do not engage in stressful or emotional conversations that may be distracting. Make people you are talking with aware you are driving and suspend conversations that can divert your attention away from the road.

Use your mobile device to call for help. Dial 911 or other local emergency number in the case of fire, traffic accident, or medical emergencies.*

Driving Safety, page 10

CERN Transitioning To Debian After Being A Longtime RHEL Institution
CERN, the European Organization for Nuclear Research, besides being well known for its Large Hadron Collider (LHC) is known among longtime Linux users as a RHEL/CentOS shop. CERN formally even co-maintained the Scientific Linux RHEL derivative with other educational/research institutions in the past. So to much surprise now, CERN is transitioning to Debian Linux...

I just had a deeply alarming 45 minute sync with our Talent Acquisition team regarding their new Al-driven resume screening tool.
They reported that the software's reduced our time-to-hire by 60% over the last month.
I asked them to walk me through the specific algorithmic parameters they established for filtering out unqualified applicants.
The HR manager smiled and said they just told the Al to optimize for digital natives with high runway potential and a youthful energy.
I stopped typing and asked her to run a demographic report on every single candidate the software's rejected since September.
The data showed a 100% rejection rate for any applicant who graduated college before the year 2010.
I explained that automating age discrimination doesn't make it suddenly legal, it just makes it highly scalable and incredibly easy to prove in court.
She seemed genuinely confused and argued that the Al made the decision, not her, so we're insulated from liability.
I had to explain that the EEOC doesn't currently accept the robot defense for federal civil rights violations.
I'm currently drafting a memo to halt all hiring until we manually review 4,000 resumes.

Your regular reminder that there ISN’T a “war on cars.” Any objective observation in most cities however, would conclude that for 60+ years there’s been a war on every mobility choice EXCEPT cars. And that’s been bad for EVERYONE, including drivers. Poster via @urbantruth.bsky.social. #UrbanTruth
