Kinko's I believe was bought out by Fedex. The one near me basically changed names but still offers the same services.

Other than using Shazam, when is this an issue for people? On Zoom or Facetime, the audio connection is almost certainly using an HFP/SCO connection, which is going to downgrade to an 8K or 16KHz sample rate regardless of where the mic

I genuinely don't understand why anyone would be interested in using frameworks on top of JS. None of them can do anything that pure JS can't do (+libraries), they just make it less readable and less intuitive compared to the orig

Bluetooth/BLE has the unique problem that you don't own the code on both sides of the wireless tx/rx. In webdev, you have control over client side and server side code and can make them work together in some unique way, witho

Interesting. What you say is true, but there is an opposing force. If someone has cash on hand when interest rates spike, they can buy when everyone else has a much harder time getting loans. So this makes things appear cheaper because ther

>that's why they crank the interest rate through the ceiling. People that are cash heavy could come up quite a bit if left uninhibited Can you clarify?

This is interesting. Never thought about how confusing it would be when banks start playing musical chairs with your mortgage. I do agree that a soft landing is still a recession. But the more people that realize that, the less soft the lan

They also use fuel, rent, and a bunch of other things. So I think it's valid to compare the two.

No one owns the airwaves. If you don't want to pay the SIG fees, simply do not use their logo or name.

Good work putting all this together. Not saying anything is wrong necessarily, but missing part of the picture.

Right, it’s more of a configuration that is being changed. But my point was that this is all above the HCI layer, so at the end of the day it’s related to the specific host-stack implementation and not to do with Bluetooth in general. I gue

Well that's doable with enough embedded memory, but it will become an issue when you want to sync audio and video. So it really is less of a protocol thing and more of something that an individual product could design in, allowing a us

This article is not about Bluetooth in general, it is a deep dive into the bugs buried within the Android Bluetooth stack. And what the writer is not acknowledging at all is that the underlying hardware being used is highly variable. Androi

The bash script I was talking about simply curls the .txt file from Dropbox, edits/appends it, then curls it back up to Dropbox (overwriting the old copy). Dropbox iOS app allows you to create .txt files if you absolutely need to take

Funny that we all resort to the same things. I have an almost identical bash script that appends and timestamps each note, but I push it to my Dropbox account using their REST APIs instead of my local file system.

>"See the section about "CBC with Counters"." That section is talking about using an incrementing counter as the IV--it doesn't say anything about a PRNG being a bad choice (in this case, the PRNG being a SHA256)

Can you cite some source for why the SHA256 of changing data isn't sufficiently random to be used as the IV?

Agree that it would be significantly easier if you had physical access either of the devices. However, with physical access there are probably even easier attack vectors (e.g. in the case of a keyboard, why not just capture the key presses

Quoting my response to Tuna-Fish: "Trying to overpower the transmission of the BT peer is certainly the technique to take (although I was hoping not to broadcast that publicly in my original post). You will still have a tough time, how

There certainly is a penalty for missing time slots (especially if you're trying to overpower the other transmitter). There are two reasons for this: (1) the victim device will have hit the time slot and the pairing process will move i

For BT, it's not a matter of transmitting first (for Wifi it would be), but rather transmitting in the exact time slot that the two devices are expecting each other to transmit. This is tightly timed in BT devices (tens of microseconds

Only keyboards that use BR/EDR are affected. BLE keyboards are unaffected.

7 octets is the minimum set by the SIG, not a mandatory length to support for all devices. For devices that transfer sensitive information (phones, keyboards, etc.), a larger key length can be enforced. This would be enforced by the applica

by jwtorres 7y ago
This is not a trivial attack. Within the short key negotiation phase, the attacker must simultaneously prevent the two devices from hearing each other, and be transmitting in their place at the exact frequency hop and interval. "The at
