Turns out to be reasonably simple, from another machine set up a file called “forcefsck” in the root of the filesystem, and it will automatically force a check of the filesystem during next boot.

Boing Boing Forward your spam to sp@mnesty.com and a bot will waste the spammer’s time

Spamnesty is a simple service: forward your spam to it and it will engage the spammer in pointless chatbot email chains, wasting their time.

If you get a spam email, simply forward it to sp, and Spamnesty will strip your email address, pretend it’s a real person and reply to the email. Just remember to strip out any personal information from the body of the email, as it will be used so the reply looks more legitimate. That way, the spammer will start talking to a bot, and hopefully waste some time there instead of spending it on a real victim. Meanwhile, Spamnesty will send you an email with a link to the conversation, so you can watch it unfold live!

The conversations are indeed posted live, and some are quite funny. It’s fascinating how obvious it is when a spammer switches from their own bot to giving a human response, and satisfying to see them fooled.

Have you met Lenny?

Hackaday Espple: A Wireless Apple 1 on an ESP8266

The Apple 1 was one of the three big hobbyist computers that burst onto the scene in 1977. Unlike the PET 2001 and the TRS-80, only a couple hundred Apple 1s were ever produced, and with only a handful in existence today, you’ll have to fork out some serious money to get a Wozniak original for yourself.

The Apple 1 experience is easily emulated, of course, but this ESP8266 emulates the Apple 1 on hard mode. Dubbed the Espple by its creator [Hrvoje Cavrak], it emulates the 6502-based original in all its 1-MHz glory, while providing 20-kB of RAM, a considerable upgrade over the 4-kB standard. The complete original character set is provided for that old-timey feel, and there’s a BASIC interpreter ready to go. The kicker here, though, is that the emulator is completely wireless. You telnet into the 8266 rather than connecting a keyboard directly, and video is transmitted over-the-air using a GPIO pin as a 60-MHz PAL transmitter. A short length of wire is all you need to transmit to an analog PAL TV on channel 4; the video below shows a little BASIC code running and a low-res version of Woz himself.

You’ll find Apple emulators aplenty around these parts, everything from an Apple ][ on an Arduino Uno to a tiny Mac on an ESP32. There hasn’t been much in the way of Apple 1 emulations, though, at least until now.

Stereophile.com Quad S-2 loudspeaker

One of the better things about bookshelf loudspeakers is that they’re innately portable. Though not generally considered the sort of music-reproduction machines you’d bring to a party, a 12-step group, or a Burning Man rave (though you certainly could), high-quality bookshelf speakers are overlooked tools in the eternal work-in-progress of introducing lovers, friends, and family to our beloved lifestyle. So during the first week or three of breaking in the Quad S-2 bookshelf speakers, I thought, Why keep these to myself? It’s strict Stereophile policy that all gear be evaluated in the context of the reviewer’s reference hi-fi rig(s), but there’s no law against sharing the joy.

One of the challenges in having a good home automation system is how to detect the presence of people in the house. I’ve had many tries on doing this, among them:

 

– Movement sensors.

These work – but for a big house you need a lot of movement sensors if you are going to have good coverage, and they do not work in practice in our house.

– iBeacons

Generally need to track a Bluetooth device, and unless you can get every household member to carry a bluetooth device, this is unworkable. The best idea would be to use a ibeacon running one a mobile phone, but these would include installing software on every household members mobile phone, not workable in practice. The option is to detect each phones bluetooth interface, but this is again not applicable for IOS devices (more about that later) – or without reducing battery life when the phone is outside the range of your house. The range is also very short, and means that you would need (potentially) a lot of receivers.

– Check for the presence of mobile phones.

You can unfortunately not ping IOS devices after that have entered deep sleep, nor use ARP to detect them.

 

As our household is run on iPhones the last has been a problem – until I found a reference to how to wake up a IOS device from deep sleep by sending packets to port 5353 (mDNS port) to wake it up, and the use ARP to check for the presence on the network.

This is a excellent way of doing detection, as the only downside is that it will lead to more battery usage (as deep sleep reduces the devices power consumption drastically). And of course it was very clear that a way to do this had to exist – otherwise you would not get alerts/messages/emails wen the IOS device was in deep sleep.

 

How to do this in practice

After installing hping3 (I did this on a Raspberry Pi by using arp-get install hping3) i made a very short shell script

#!/bin/bash

sudo hping3 -2 -c 10 -p 5353 -i u1 $1  2> /dev/null 1>/dev/null

arp -an | egrep -w $1

 

it works (though not perfectly) as it wakes up the IOS devices, and responds like this when it finds a device

First a good beer

This is a home brewed Brewdog 5 AM Saint – looking and tasting extremely good if I say so myself.

Then bread with honey

One of the best english honeys I have ever had. Bought at the market in Winchester. A bit hard to get out of the pot – but tastes really good.

Just finished the brew – and here are a few post-brew notes.

– The BrewDao brewing page enclosed with the pack is a bit lacking in details, so I used the standard Grainfather calculations for how much water to add to the sparge. This turned out to be wrong, as this should be 25 Litres, not 28 Litres as assumed in the Grainfather calculations.

– On the positive side using a keg hopper to keep the hop pellets in made cleaning a lot easier, and the finished product a lot clearer.

It’s now all fermenting – so in a couple of weeks I can report back on the results.

Never brewed this particular one before – and as it includes dry hopping it will be the first time I can do this with all the hops in my hopping container, hoping to make the finished product slightly clearer.
