I once met a person that never drank water, only soft drinks. It's not the unhealthiness of this that disturbed me, but the fact they did it without the requisite paperwork.

Unlike those disorganised people I have a formal waiver. I primarily drink steam and crushed glaciers.

  • Thankfully, it must have been all volts and no amps so I was OK, even though I let out quite the yelp. 😁

    Complete myth. Please don't repeat this. It's not even remotely close to a generalisation, it's completely wrong and dangerous.

    (Sorry, pet peeve of mine. Have had family members happy to play with mains wires but terrified to touch car batteries for fear of death)

    100mA through someone can be harmless. 1mA through someone can be fatal. Lethal conditions occur under certain complex circumstances involving not just voltage/current, but frequency, exact waveforms, duration, contact points and the individual's physical parameters (human skin resistance varies a LOT, it's not an insignificant factor).

    The most commonly encountered electrical hazards involve 50/60Hz 120/230V mains and hand/foot dermal contacts. This is a lethal combination that can cause heart fibrillation. Even 5mA or 100VAC can cause this (sometimes you will see lower numbers cited, "it depends"). Death can occur a day later, see immediate medical attention if you believe you have been shocked by mains wiring.

    At very high frequencies our nervous system is not sensitive, so we can pass larger amounts of current or deal with higher voltages without much harm. I'll still hedge this with "it depends", you can get thermal burns (which if on the eyes includes blindness) and pathways through the body vary with contact points, changing the risks.

    Static electricity discharges can be crazily high voltages and currents (many amps, sometimes hundreds of amps). Yet they are not a hazard.

    The high voltages in your CRT will supply very high currents when applied to dermal contact points on the human body. This will likely induce involuntary muscle contraction. Prolonged contact could cause burns and unwanted chemical reactions to occur internally, but is unlikely to cause heart fibrillation because of the non-repeating DC nature.

  • I was young and did not have access to soldering irons. So I bridged the two pins with aluminium foil and sticky tape.

    It would slowly peel off and my controller would suddenly stop working mid game. I couldn't reboot the console because I couldn't save (no VMUs). So I'd fix it live -- I'd leave the screws out of the case, jiggle my fingers in there and fix it.

    This was fine, worked for most of a year. Until I killed the console by accidentally touching the controller PCB to another PCB whilst doing this fix. I still have the corpse somewhere, to this day I still feel awful about it.

  • Raspberry Pi Announces Price Increases Due To Rising Memory Demand

    Jump

  • Bugger!

    Recently asked raspi foundation if they could do a sku with less ram for order quantity 1000. Answer was no.

    IIRC the lowest skus with wifi and mmc for the CM4 & CM5 are 4gb & 8gb respectively. We only need 1gb of ram.

    We were going to the CM4 to save 10usd/unit, at the cost of dramatically lower emmc write speed (slow factory programming times). I'll have to check how much worse the price gap is now :D

    Very much wishing for a competitor with reliable wifi drivers, upstream support and sim prices (or lower). Can't wait for universal distro images that work on any sbc too ( continues dreaming )

  • We have POSIX at home

    Jump

  • If something is POSIX compliant then it's very likely to work on any Linux, BSD or the like; and probably very easy to port to windows. It's a sign that the developer is willing to go the extra mile to make users' lives easier.

    N.B. "POSIX compliance" is not just considered in black or white terms, it's also done in degrees. There are many things that have never formally been changed or been specified in POSIX but informally things have evolved. By attempting any level of compliance (or a similar equivalent) you tend to be doing better than most software.

  • Were you disappointed when Perfect Dark got canceled?

    Jump

  • PSA: Perfect dark (original n64) has a community-made PC port that's beyond excellent.

    https://github.com/fgsfdsfgs/perfect_dark

    I hated the original because the low framerate gave me bad motion sickness. The PC port is like magic by comparison.

  • Notepad++ DLL Hijacking Vulnerability Let Attackers Execute Malicious Code

    Jump

  • Bogus CVE. Spam.

    From the PoC:

    Replace the original DLL (such as Notepad++\plugins\NppExport\NppExport.dll) with a DLL file with the same name containing malicious code

    If you replace parts of a program with malware then you can get malware to run. This is true of all software.

  • Read-only, or the ability to edit filenames & upload files?

    Read only: as per other answers here, basically any HTTP server. The easiest one I know would be darkhttpd, because it requires no config files and can be run without root.

    N.B. Only worked in Chromium (not Firefox) for me. Could be due to addons though, not sure.

  • ‘Wake-up call’ for Australian universities as 70% suffer a fall in latest global ranking

  • FWIW there are dozens of university ranking systems and every university says "look how well we rank in X!". It's been 10 years since I looked, but I think I recall some of them being funded by unis too.

    Nonetheless I agree they're doing stupid stuff that's not in the interests of students, staff, the country, humanity and education in general. Alas it takes them many years to feel the bad effects of bad decisions.
