The secret is to trick DeepSeek and misspell Tiananmen. You see, Artificial Intelligence is more artificial than intelligent. Here's the prompt I used on self-hosted DeepSeek-r1:14…

Oh, thank you. I hadn't test it under Big Sur. It seems there is an incompatibility with Big Sur in the Sparkle Framework (I use it for updates). Will look into it.

No, I store on OS-X's keychain. You made a fair and necessary question but I'd be embarrassed to even think about storing the password on disk, even if encrypted.

> I wish they added "unlock Mac/use id on Mac with iPhone". Me too. So I made a program that does exactly that: https://www.gadgetish.com/osx.html It also works with Android phones…

Sorry for the shameless plug, but for those without an Apple Watch I've made a program [0] that implements the Unlock Mac with Bluetooth for any other device, including Android pho…

No, there isn't yet. Sorry. I'd have to create an app for Apple devices to connect to Windows and allow rssi readings. But I don't have the time to do it now.

BLEUnlock only works with BLE devices with a static MAC address. All Apple devices do that. However almost all Android devices don't do it. My solution uses classic Bluetooth, whic…

Hi all, author here. On macOS (Mojave, Catalina, ...) you can lock/unlock the computer with an Apple Watch by proximity. But I don't want an Apple Watch... So I made a program to r…

Regular expressions do cover most of the basic cases. It will not handle some of them. But I discovered that partisan politics follow a Pareto rule, of sorts: 80% of the talk is ar…

Beware: the devil is in the details. The trick is to choose the most provocative, trolling or insulting words. I let people discuss generic terms such as income distribution, fisca…

> Watching distant cousins fight about politics I've long been cautious to step into the WhatsApp hysteria going on here in Brazil. But the last (disgraceful) election here was the…

Frankly, I am not very happy with it too. It is a concept from biology, designates the specific sensitive skills that each species has to detect their environment. I guess I just w…

Hi, I made this. This is a program (for Windows 10) and an app (for Android) that allows automatic log in/lock on a Windows PC. It works either automatically (by measuring the stre…

I love and use KeePass on my PC, although not on Android. Will try it, thanks for the tip. However, a problem I have with KeePass is that I can't get my wife to use it. It is too c…

Funny, I am doing something like that now, but using an smartphone with a fingerprint reader, instead of a Pi and sending the password through Bluetooth (adding USB might be a good…

> Not if the attacker stops the relay right after the PC is unlocked. No, if it happens the program falls back into the "user is away->lock the computer" mode.

> an attacker could just replay messages between the two devices and boost the signal without being able to decipher the contents As a simplified version of a MITM attack? That is …

> Car thieves have been using signal amplifiers Very true. But I am using Bluetooth and it has much better security protocols than the plain simple radio-frequency signals for car …

I am about to finish a more limited implementation of this idea for Android Wear smartwatches and Windows. It works by measuring bluetooth signal intensity (rssi). I already made a…
