Attempt to clean up tech area has shocking effect on kit

Re: Cleaners and lights

...Just like my tale of an University lab where all the sockets changed from 110V to 220V when you turned the lights off...

...Everything that needed a specific voltage on input would release blue smoke or spit its fuses out, every weekend... which happened for 3 weeks in a row until I visited it myself...

...It was my sister's University, so I would usually give her a ride on Saturdays; that day she mentioned her plight with the recent lab expansion, and its fuse-popping, sparkly sockets...

Re: No clip

In Brazil, we have pure Ethanol cars (would that be E100?) but these never induced static mishaps above their gasoline counterparts... to a significant statistic, that is.

All the employees handling the fuel pumps use 'grease monkey' cotton overalls and rubber sole boots for some obscure reason... and the extra warm and moist weather precludes static buildup anyway.

In fact, the only occasion where such things ever happened were those where that same grease monkey was SMOKING, and shoved his face on top of an open tank of a fuel tanker, cigarette butt still lit on one hand...

I believe the low temperature just precludes MOISTURE in the air, which prevents the dissipation of static charge that would normally occur.

So yes, E85 is easy to ignite at -8 Celsius only because the dry air is, counter-intuitively, non-conductive.

Grounding the work force... permanently.

A friend of mine told me about his previous job.

They were about to move their business into a new building... that the company would build from the ground up, to better suit their demands upon expansion. But, before moving, they had to install everything in it, including all the electrical bits. He was responsible for the IT part so he lets know of the grounding demands: about 75 wrist straps in an assembly line, and means to ground them, nothing complex. Well, let's just say the Sparky in charge wasn't exactly AWARE of a few demands for it.... or building codes for that matter....

...like not using the same ground for WRIST STRAPS and LIGHTNING RODS. This friend of mine, on the first inspection visit, quickly noticed this weird line across the ground, before the installation of raised floors... hooked up to the rather thick lightning rod lines running outside. About 75 people would've met their demise in the same manner as anecdotal Benjamin Franklin. The first electrical storm on the brand new facility would be the last for the majority of the workforce, no matter how thick those grounding lines could be. Stranger yet, nobody else noticed it.

Would you use a wrist strap hooked to a lightning rod? I guess not.

Gaming doesn't demand bandwidth, it demands low latency.

"And then of course there is the explosion in online video gaming – yes. Fortnite, but others too. Plus the cloud storage market, video conferencing – FaceTime etc. Smart homes. Internet of things. They all need bandwidth."

STOP. RIGHT. THERE.

Online gaming consumes ridiculously low amounts of bandwidth. Remember dial-up? Yep, you could game - COUNTER STRIKE - with dial-up. I measured my own bandwidth (DU Meter, anyone?) while playing GTA - game sessions with 30 people, vintage 5-year old netcode - and it takes about 10 kbps per user, A FRACTION of dial-up per gamer on your session. And that's being generous. Games are like chess - each PC relays what are they doing to each other, like moving to x y z, and shooting at t, u, v. Every move is relayed in extremely short code. The catch here is LAG. This demands high-quality and low-demanded routers, if you want decent amounts of lag.

Now, the others - video conferencing, facetime, these do demand bandwidth. Not just that, they require QoS and full-duplex connection. Storage needs just raw bandwidth, but it doesn't need the packets to be in order, or low latency, or they must be streamed continuously, they can be sped through in bursts and half-duplex, as long it averages out in a high value.

Netflix is pretty much storage in reverse. Once the receiver can get a large bulk in cache, as long it averages out, the player can't tell the difference, and will play smoothly. So is Youtube.

Beer oclock. End rant.

Strewth! Aussie ISP gets eye-watering IPv4 bill, shifts to IPv6 addresses

BIOS IPv4...

What I think is gonna happen is that IPv4 will become a back-channel of sorts. Only management purposes, while the thick of it goes IPv6.

My android phones don't give a crap when they latch onto my router with an IPv6 number, but oh boy would I get annoyed if I had to type one of those by hand (I never did, to be honest). And the router itself still needs an IPv4 address anyway for my own subnet.

So, it's easy to type 1.1.1.1 for your DNS eh? Who'd known? Who could've guessed?

It's like booting an old PC that relies on BIOS, then it loads higher-level drivers as it goes...

Trainer regrets giving straight answer to staffer's odd question

Luiz Abdala

A certain movie and an Artillery piece...

I remember a certain movie, where a small village with "simple folk" was caught smack-dab in a strategic defensive position... it was either Italy or somewhere in the Pacific... but it was definitely WWII.

So they parked an Artillery piece there... those truck-towed beauties with 88mm or 105mm or similar cannon size on them.

So, to avoid injury due to improper handling by untrained personnel, the sergeant starts chanting:

-"do not the load the upper feeder with ammo cartridges"

-"do not retreat the (pin) to feed another cartridge"

-"do not close the breech into lock position"

-"do not use the levers to rotate the barrel"...

... you see where this is going. (I don't remember the words, but they were foolproof...)

Eventually, they spot an Axis ship, and no soldiers in sight to operate the Artillery. They recite, word by word, those instructions, and manage to hit the ship... Lovely movie.

Does anybody remember its name, by any chance?

Windows 95 roars once more in the Microsoft round-up

Luiz Abdala
Go

I remember...

A friend of mine had a game rental store (cartridges for Genesis and SNES back then) running a Windows 3.11 app in a then several-orders-of-magnitude faster Pentium 4 hardware than the 3.11 had ever required.

It ran on bare metal, no emulation or virtual machine here. And it was FAST.

It was so fast, in fact, that it could freeze in your face, and he could hit the reset button and finish your order before you could complain it had frozen.

It was not FAIL-SAFE. It was FAIL-EXPECTED. It WOULD crash, but it could recover in 15 seconds, I kid you not.

Some lesson can be taken from here... it can fail, as long it doesn't take long to recover. Either this, or you design it not to fail for long periods of time...

The guy running a Windows 95 (which we loved) over a MacOS (that is nearly failproof) is a god damn GENIUS.

Oddly enough, when a Tesla accelerates at a barrier, someone dies: Autopilot report lands

Luiz Abdala

Dead man switch?

Quick reminder: a CFIT can happen with either man or machine, it is not specific. The Tesla crashed just like an airplane, and nobody knows why or how either one that could avoid it, did so.

Dead man switch?

Trains are able to follow a precise path, yet we still have accidents with them.

In one in particular, the man on the controls could not see the appropriate signaling at that particular time of day, and the investigators verified that fact actually was the causing factor, again, reinforcing, at that particular time of day, the signals could not be seen.

In other occasions, the men behind the controls fell ill, and were unconscious prior to the crash.

How could a sane person ignore the fact that his vehicle was headed toward a concrete barrier at 70mph? Was he awake/sober/ in command? Did the man have a seizure or heart attack or anything that would impair his ability to swerve away or brake? Could he SEE the barrier, did he have sun in his eyes, like James Dean?

If his car crashed on its own due to autopilot going titsup, why where other 3 vehicles involved? Did the other people also fail to notice the erratic behavior on the Tesla? Why didn't it crash SIDEWAYS, because that's what people in control would try to do, wrestle the controls?

Too many questions. Not enough answers. There is even a specific term for when it happens on airplanes, crashing on the ground with a controlled aircraft... Controlled Flight Into Terrain - CFIT.

This is a standard CFIT scenario. He crashed into the barrier without explanation, neither equipment nor crew could detect the disaster until too late. Finding the likely cause would fall back into the other scenarios - equipment failure, pilot error... or into what must be changed for ALL cars that are dealing with automated driving, just like Boeing has been doing since the 70's.

No, seriously, why are you holding your phone like that?

Luiz Abdala

All generations below mine...

...abhor actual phone calls and send voice messages through Whatsapp instead.

Which kinda makes sense, because actual phone calls are charged by the second, take longer to negotiate and are prone to failure, while compressed audio through whatsapp media is charged by the kilobyte in their data plan, is time-delayed instead of simply failing to transmit, and the net result is actually cheaper. Plus, the interlopers can repeat the messages to their hearts content, and those messages can be checked, before sending, for clarity.

Here is the jump to the topic: the messages are recorded using those 90 degree angles so they can see the screen at the same time they are recording, just in case the other party decides to send an emoji or (gasp!) text at the precise moment they are recording.

And during playback, they turn the volume of the phone down, in order to attain some privacy, and again hold the phone at that odd angle so they can hear the media like it was an actual phone conversation, but not being bothered by actual headphones, bluetooth or otherwise, while keeping the hand position to resume typing, or access once again the record button, at record speeds, no pun intended.

1 hour lost in my commute, observing 5 people doing those actions at the same time, in the metro, allowed this observation.

In Brazil, of all places...

...they don't call it fibre or fiber unless there is a glass-filled thin wire plugged straight into the ISP-leased router on your desk.

They call it just 'cable' or 'Internet cable' at best, due to the commonality and ubiquity of a service provider first using DOCSIS 3.0 (over coaxial cables of course) common to TV's, only having actual fiber on the light pole outside. This service provider took advantage of using TV infrastructure (being a cable TV foremost) to advertise the new method of (broadband) Internet access.

The other service providers use POTS cabling and xDSL, again leaving the actual fiber cables on the poles. Only when you ask for 100+Mbps services, they will go the extra mile, rip everything copper off, and place another section of actual fiber all the way inside.

It turned out so because all ISP's, in one way or another, were behind the evolution curve kept by the clients, that DEMANDED proper installation of newer technologies, after having used dial-up for what seems like millennia and KNOWING that those were COPPER cables, and not fiber, going inside their homes.

The entirety of the Internet service provided in the country trickled down from enthusiasts and first-adopters, into the clients, families, employees, and colleagues of where the first-adopters worked and lived.

Only after the dial-up crowd was appeased and the looming threat of suing for false advertisement ended, actual advertising offering "cable internet" coupled with TV and phone services took place to a broader audience. The generic term was broad enough to ensure marketing couldn't possibly f*** up this time.

Microsoft XML crazed fever extend to games.

Microsoft Combat Flight Simulator 3 and Age of Empires 3 had all the game variables in XML files.

Things like "points of contact" of aircraft. 3 points with Z= 0 are the landing gear. Delete all the others and enjoy your nigh-invulnerable plane. Delete these 3 and watch the airplanes cross the airfield floor and explode when they go underground, even before the game begins.

Age of Empires 3 had all the variables spelled out, like TrebuchetAttackForce = 20 or something like that. Replace that 20 with 255 or 65536 and watch all your enemies buildings crumble beneath a single catapult attack. But I think that on AoE 3 only the heroes were identified, so if you changed one of these generic attack units, they would change for BOTH sides, so you could mod your game to your heart's content, knowing that your enemies would get the upgrade too... with hilarious results.

I miss the old days...

...when the hardware said (lets use IBM) "IBM" outside.

You could be sure that every. single. chunk. inside. said IBM, or Made by IBM, or manufactured at [IBM address]. Every single part had the IBM logo, either embossed, or printed, or had at least a sticker. Every manual was carefully constructed, detailed, that even an idiot (hello, myself at age 16) could take it apart with a Phillips screwdriver. And it had pictures! Changing hard drives? Page 18! Adding RAM? Page 12! Your wife dumped you? Annex 12-b! It looked like they gave a fresh box to an intern and told him to put it together, and everything that went wrong on a statistical significance was logged and added to the manual.

Even things like flash a BIOS using a freaking bootable DOS disk were detailed, from which file to download, to "insert disk on drive a:" to how to find the reset button on the carcass of your model. They took you by the hand, and politely opened the limo door for you while holding an umbrella. You felt a VALUED CUSTOMER, you felt CARED.

These days, everything is licensed, it betrays the confidence you placed on this or that company, because almost ANYTHING is done through third-parties, where the Main company does NOT vouch for their warranty, or quality, or whatever.

(Not everybody. Shout out to AMD, that replaced me a Ryzen that never booted with a new one. RMA and a fresh proc across 2 continents in 15 days.)

We lost something valuable here.

HP is the blackest. Not the ink.

They seep blue ink along with the black ink, so you eventually need a replacement for an ink you didn't use. Specially if the color cartridge has all three colors into one body.

They say the ink is low when it is half full.

They lock third-party cartridges out, with legal proof coming from Australia.

An ink cartridge costs 0,20 currency* to manufacture, but it costs 20 full currency* to you.

Bulk-ink printers from HP are designed to fail a lot sooner than the ones that use cartridges.

(*) whatever your currency is, that is the scale of profit.

IT Angle

Re: Replacing the batteries.

Don't forget that the last 20% of said batteries are off-limits, unlocked by a special check-box that says, explicitly "I will make a long trip and require the full charge available", and said checkbox will clear itself in 72 hours. Some Tesla owner can show you that software button. Otherwise, you never get to fully charge the car to its full autonomy.

And I assume those remaining 20% (AND HERE IS YOUR IT ANGLE) gets to join an over-provisioning scheme, where these cells won't be actively charged and discharged, and will be probably used like that extra space in SSD drives, to increase durability of the battery pack, by reducing the number of cycles in each cell.

Special Jalapeños...

We had a very special jar of jalapeños... that sat on the mess hall, behind a Nuclear Power Plant Control Room.

The few employees that had the privilege -or orders - to eat there were aware of that special jar, regularly topped up with the purest olive oil. Never a single piece of those peppers was removed from the jar - except one - since the power plant was commissioned in the year 2.000. It was 2003 and it was still there, looking exactly like a fresh bottle, bought in any store. The bravest ones would serve a few drops of that liquid in their meals, with no ill-effects in the short term. Even the most insipid grub would spring to life with a single oily drop of that vial. I have tasted it myself, and survived to tell the tale.

It was said that the Power Plant was jump-started with a single piece of jalapeño, from that flask, neutron emitters be damned. Since the lights on that mess hall were never actually turned off, fed from the same circuit of the control room, in a constantly inhabited place, nobody knows if that thing could actually glow in the dark or jump-start a Nuclear Power Plant, and nobody will ever know.

My old man used to live near a FM radio broadcast antenna. Very near.

Under it. Neighbor to it.

You turned the LP player on: you could hear the radio.

You turned the tape deck on: you could hear the radio.

You turned the amp on: you could hear the radio.

You turned the shelf speaker for the PC on: you could hear the radio.

You stretched a piece of copper and bit it with your dental fillings: you could hear the radio.

So you couldn't record anything. At all. Unless you wanted some random song or the evening news playing in the background, no you couldn't.

One day, he bought a stereo system that would PURPOSELY speed up the LP, and speed up the cassete tape recorder at the same rate. You could take 23 minutes to copy 45 m. worth of music.... with the freaking radio songs played at half speed, off-tune, in the background. It was haunting to hear some tunes at half speed.

I don't miss the experience of trying to filter a FM broadcaster out, that was violating every single local FCC rule.

Meltdown/Spectre week three: World still knee-deep in something nasty

Luiz Abdala

Re: A tactical mitigation/solution...?

If a chip can be reliably run at 10% overclock, they will give a new marketing moniker to sell it for 20% more.

Locked multipliers chips were sold SOLELY based on that. Entire generations of Celerons were underclocked gems that could be taken into stratospheric overclocks, provided you could cool them and the memory could keep up with them.

The entire overclock community was BORN exclusively of the fact that some CPUs were being purposely throttled and sold under different price tags, and someone discovered that the 50$ chip could perform just as much the 100$ chip, and the 100$ chip was the the same 50$ part, overclocked into the edge of electronic migration.

One certain old-school AMD chip was even "hard-locked", but this could be unlocked/overclocked if you shorted 2 pins.

127V or 220V ?

My sister was working at a University Lab, as an undergraduate, and the place had gone under a major expansion and reform. Repainting, new furniture, more sockets, more lighting... the place was pretty much turned on 24/7 for lab experiments, except for illumination...

...but some sensitive lab equipment never survived the first weekend. And then 3 weeks in a row. Computers and more mundane gear as TVs survived without a problem.

So she asked a lift to complete an experiment on a Saturday, then we would go for lunch, so I waited for her to complete her task, and she explained the whole story. She turned off the lights and hell broke loose. Again.

We are not sure HOW the sparky managed to do it, but the 127V lights were somehow connected in series with all the power sockets...

As soon you turned all the lights off, all sockets would switch from 127V to 220V. I noticed literal sparks out of an empty socket when she turned the lights off, which shouldn't happen. At all.

A multi-meter and some turn-on-turn-off-lights later...

TVs and computers had multi-voltage PSUs and didn't give a damn about the voltage they were being fed... while the sensitive equipment, being really old, had fixed voltage PSU inputs...

I've never seen or heard of such a feat.

Q: [But why is it necessary to animate every blade of grass waving around in the background while I play Farcry ?]

A: https://en.wikipedia.org/wiki/Escapism

People want to forget about their dull daily lives and immerse in something pleasant to the brain. Somewhere on the webs it is said that the visual cortex takes 70% of our brains, audio takes another hefty chunk of the remaining... so fooling them both will immerse you pretty handily.

And yes, my GPU also has more computing power than 2x my CPU, and guzzles just as much 'leccy as the whole rest of the system.

To almost complete the immersion of brain into pleasant things, you need a beer while playing.

Name your research project Quake.exe and call it a day.

Just be sure to load some gaming on that research machine and nobody can utter a single word about EULA breach!

Time to fire that CS:GO server weekend section up!
