Scalpel! Superglue! This mouse won't fix its own ball


Re: Ball crud

Actually I've never had any serious complaints about any Microsoft PC peripheral hardware.

The sidewinder Joystick (with USB connection) is still going, as are the 2 x intellimouse optical (although I did have to replace the USB cable on one after the wires broke internally at the flex point where the cable enters the mouse), The Xbox style controller with USB just works and my sidewinder mouse with all the options keeps soldering on...

Sometimes I think Microsoft should have gone into hardware because this stuff is so reliable, but then I remember reliable stuff ends up bankrupting companies so I'm just glad I got some quality peripherals before they bailed :-)

Re: This is one thing...

This is anecdotal (because I'm too lazy to do the research), but a long time ago one of my lecturers who had been a Electrical engineer with the armed forces in the UK explained the following to the class.

AC is used principally because it is is very easy to transform between HT power lines running at 15+KV and the street power, requiring only a passive transformer with the correct windings to do the conversion (so yes much cheaper over all).

Additionally he mentioned that AC was safer than DC because in a AC jolt your muscles spasm so in accidental contact you will usually be thrown off the wire, which is why AC electrocution of dogs/elephants/humans looks so horrifying. In a DC jolt your muscles will clamp and so if it happened you where holding the live wire it was likely you would continue to hold the live wire and just cook. Apparently Edison was loosing more linesmen for his DC systems than others where with their AC systems and put a lot of effort into hiding this fact.

He also mentioned that the survival rate for 200+ AC mains was better than 115 AC mains because if you bridge your hands across 200+V the current across your chest (based on bodies internal resistance V/R = I) has sufficient amperage to stop your heart, which usually restarted after the power source was removed and if not CPR could be performed. At 115V apparently the current induced across the chest is more likely to cause the heart to fibrillate which will kills you and makes CPR less effective requiring a defibrillator to save you.

As indicated above I've been too lazy to do the research to verify these statements, but he was a very very good lecturer who knew his stuff so I've never had a reason to doubt it. I'm willing to accept correction from others who know more though.

Buying a Chromebook? Don't forget to check that best-before date



I think instead extending the warranty laws (which is essentially what is being spoken about when talking about support for a certain amount of time after the purchase date), there should be an update to the advertising and packaging laws to make it a requirement that the manufacturer must clearly indicate the earliest manufacturer's expiry date on the external packaging. (This should cover built in hardware obsolescence as well as software)

Think best before date on semi-perishable products you buy at the supermarket.

In the same way that people think twice about buying a product that has a best before or expiry date that is due to expire in a week, people may* think twice about buying a Chromebook where the packing clearly states than in 6 months time they will not be able to get security updates.

* may because it would probably take many years of encouragement before average consumers start to examine the product packaging properly before making a purchase, but at least the technically competent among us wont be caught unawares about a rapid built in obsolescence...

Re: Luckily

I prefer the quote from James Nicoll relating to the English Language 'adopting new words...

"The problem with defending the purity of the English language is that English is about as pure as a cribhouse whore. We don't just borrow words; on occasion, English has pursued other languages down alleyways to beat them unconscious and rifle their pockets for new vocabulary."

Put a stop to these damn robocalls! Dozens of US state attorneys general fire rocket up FCC's ass



The frequency of calls I was getting about a year ago lead me to unplug the phone, resulting in complaints from relatives that they can no longer ring us. (I also have no intention of telling 90 year old grandparents to use a mobile instead). To resolve this I ended up setting up RasPBX on my Pi3 and configuring it so that whitelisted calls ring the home phone and everything else gets answered by Lenny, the calls are recorded for my entertainment and emailed to me on completion.

I went from being irrationally angry every time the phone rang (like Robert) to looking forward to the next scammer call so I could tweak the system and attempt to trap the scammers on the phone longer, this has kept me entertained and engaged for hours and I've learnt a lot about Asterisk and telephony in general as well.

Since first configuring the system I have managed to get the system to press 1 when an IVR call comes in in order to try to get connected to a human, and also randomly select Between Lenny, Astycrapper (Jordan) and the "are you there" child recordings.

Incidentally I have discovered in my fiddling that at least some scammers seem to be utilizing poorly configured (probably asterisk based) PBX's themselves, they seem to have the incoming calls being dumped into a conference type call they are already on and that the DTMF recognition is still turned on but without any actual error handling configured. I have had multiple calls where Lenny has incorrectly identified the speaker as a IVR robot and pressed 1 only to have the call suddenly disconnected by the remote end when the scammer PBX barfs on the DTMF tone.

I have wondered if you could look up the default Asterisk conference DTMF commands and find a way to cause greater disruption by shutting down the conference or conferencing in external parties (like the police) to the call vie the scammers PBX.
