Mozilla, Microsoft drop root Certificate Authority • The Register

Updated Mozilla and Microsoft have taken action against a certificate authority accused of having close ties to a US military contractor that allegedly paid software developers to embed data-harvesting malware in mobile apps.

The CA, TrustCor, denies this, but has not responded to direct questions at time of publication.

After a lengthy discussion between staff at Mozilla and Apple, security researchers and the CA itself, Mozilla program manager Kathleen Wilson said the org's concerns were "substantiated" enough to set a distrust date of November 30 for TrustCor's root certificates.?

The back and forth took place on Mozilla's dev-security-policy (MDSP) mailing list, and you can read the full discussion there. Microsoft didn't participate in the conversation; instead, TrustCor executive Rachel McPherson claimed that Microsoft had set a distrust date of November 1 for her company's certs.?

In 1947, the United States voided all of the Nazis patents and put all their non sensitive technology and research into the public domain for all to use without restriction.

This was actually a very big deal – the Nazis had some of the world’s best scientists – and their development pushed forward computing, electronics and audio recording enormously.

JD1914 Relays

My old Plymouth Sundance had the low and high beams controlled by a JD1914 latching relay – you pulled the light stalk towards you to switch between high and low. Always thought it was a stupid design even if it was simple with one wire to the relay – throw back to the floor switch.

I much prefer the modern configuration where you push the stalk forward for high, towards you for low. I assume the turn signals and headlight bright control are a signal sensor that sends to the computer over CANBus which tells the computer to probably blip, well probably a JD1914 relay, because it’s cheaper than having two regular relays and you can keep old designs to this day and don’t have to constantly power the relay.

Break the Headphone Jack On Your Laptop? Get an Inexpensive USB-to-Audio Dongle

Break the Headphone Jack On Your Laptop?
Get an Inexpensive USB-to-Audio Dongle.

Last week I did something stupid — I left my headphones plugged into my laptop when I headed off to the office, breaking off the headphone jack in my less then two year old laptop. I found an inexpensive, plug-and-play alternative that works just a well as a headphone jack.

An USB-to-Audio dongle plugs into any USB port or hub and provides an analog headphone jack audio out. It’s a fairly tiny device with a male USB connector on one side and a headphone jack on the others. iPhone users often use a similar device to connect analog headphones to their phones.

The dongles are under $10 on Ebay and Amazon and can often be found on AliExpress direct from China for less then $5. The sound quality on the one I bought was basically the same as the laptop. The dongles works well, because USB-to-Audio standard is part of the USB standard and most software automatically supports it just like a conventional headphone jack.
