Network sniffers find COVID-19 did not break the internet – though it was behind a massive jump in outages

5G protester outages?

How many recent outages have been caused by 5G sabotage? Some idiot trying to burn down a tower ended up damaging the fiber going to work causing nearly a whole day outage due to the fire being started in a pit.

I've started collecting magnetrons out of dead microwaves. I'm not sure if I should mail them to the idiots I find or just put them up on sane neighbors roofs.

Should I have used the warning icon rather than the fire icon since that will be inside the box with "warning microwave generating magnetron!"

University of Cambridge to decommission its homegrown email service Hermes in favour of Microsoft Exchange Online

Re: Business as Usual

Their dashboard has plenty of useless data. So the site downloaded 90 gb of data? Over what time frame as it isn't mentioned except in conflicting forum posts. Throw in a white text on black design mixed with black text on white for a nearly unreadable system and version specific chrome requirements make their web interface look amateurish. Their support forums tend to have their search engine optimization around the wrong way so looking for a problem will result in the 5 year old solution, not the current one. If they put google parseable dates in their metadata would fix that problem. One USG has dropped out 4 times in the last month requiring power resets. That was after replacing a unit that died more than a dozen times over the last few months and it usually happens in the wee hours of the morning. Being a "cloud" device, there is no viability into it and a serious lack of logs that can be pulled off it after a reboot. Someone needs to tell them about a watchdog feature. Their radios do tend to work well but the USG seems like a joke of a product and I'll be looking for a replacement if they can't find and fix the problem real soon as it isn't up to the task.

Keen to go _ExtInt? LLVM Clang compiler adds support for custom width integers

This is amazingly useful when it is needed

I think it should have Endianness included in there as well and I'm not sure it should be limited to integers as it could be fixed point. The implementation of pointers will get weird as a now a pointer to the 5th element of a 5 bit array will be larger than a pointer to 64 bit int in classical architectures as it needs to include a real memory base pointer and an offset as well as a size. It would also be useful to be able to tell the compiler what the base char, int and long sizes are. An option to set int=31 and crash on overflow conversions would be very useful for testing most C code.

Stripe is absolutely logging your mouse movements on websites' payment pages – for your own good, says CEO

The stripe code seems to have been written by someone who uses tabs and not windows because all the stacked windows will be sending data at the same time.

Police drone fliers' wings clipped to prevent them bumping into real aircraft

Re: Mixed measurements

In metric parts of the world, the Feet in aviation aren't a real vertical distance to the ground but an approximate distance based on air pressure which drives the altimeter which is adjusted to a nearby location and adjusted periodically during a flight. Above a point of about 10,000 feet, the altimeter will be adjusted to 29.92 inHg or 1013 mb. This result is in a low or high pressure system, the 500 ft separation of planes is slightly different than 500 ft, but they don't hit each other because they are all using the same reference. A pressure altimeter when calibrated is more accurate than a GPS altitude.

Feet aren't used for horizontal distances in metric countries. Places like Australia which mostly copied the US FAA's rule book down to the section numbers, rounded all the nice round feet to nice round meters (1000 ft became 300 meters, not 305m) but sometimes they rounded up, sometimes down.

Consumer reviewer Which? finds CAN bus ports on Ford and VW, starts yelling 'Security! We have a problem...'

Separate but still connected?

Late 1990s Saabs had 3 CAN buses. One for the ABS, one for the Engine/Transmission systems and a third for everything else. The speed of the car is determined by using the ABS sensors so as long as one wheel is rotating, it have a very good idea of of the speed and it took me about an hour on an icy parking lot to trick it. The thing is the radio needs to know how fast the car is going so it can make slight adjustments to the volume depending speed so I wonder just how isolated the busses are.

Kids these days...

I overheard some girls on a train talking about how they install virtual machines on their school provided laptop so they can have games and how there is a hack that makes the school image look like it has all the memory it should have. They also discussed how they had used social engineering to get most teachers to drop the anti-plagiarism software by jacking up the false positive rates. I expect the kids weren't over 12 based on the expensive school they attend.

Who needs the A-Team or MacGyver when there's a techie with an SCSI cable?

SCSI Hacks?

A friend had an Amiga with two SCSI cards. There was a program on the Amiga that looked like a block device to a PC that thought it was the "master" on the chain. The result is he could rapidly backup and reboot the PC much the way the virtualization allows today as well as doing RAID0 style merging of small Inexpensive (aka rejected from other projects) disks. When he ended up with a Sparcstation, it too went on the SCSI chain and it allowed him to work on the same files with the PC or Sun without all those expensive network cards as long as he remembered to only have one system active at a time.

Need 32-bit Linux to run past 2038? When version 5.6 of the kernel pops, you're in for a treat

Re: WS2003 redux

time_t didn't need to be an int which is why it was its very own type. A 32 bit singed was used in the AT&T and BSD Unix and that managed to find its way into places where a time_t was cast to an int for portability . A time_t would be 36 bits on 9 bit machines.

Re: ...why Microsoft taught people to hit Ctl-Alt-Del...

Ctrl-Alt-Del could be intercepted on x86 computers of that era. The 1st IBM PCs (5150, the ones with cassette ports) were the ones where it couldn't be intercepted as it sent a hard interrupt but that was removed by the days of the XT which implemented the reboot code in BIOS. Since an PC couldn't use that key combination, no early DOS programs supported its use and it was nearly unused by the time Microsoft needed a "force a login window" key. It had been used by a few games to adjust how they worked in "turbo" mode.

Style vs Content

I don't care about design, I care about content.

So many CSS "experts" don't seem to understand they need to define things relative to character sizes and not pixels. If I zoom in to read something, everything needs to zoom in which seems to be something the chrome broke a long time ago and has just made worse with the newer versions. I use Safari because I can right click on all images and open them in a new window where I can zoom them enough to see. Lately Chome has decided I don't need that option on all images.

There is other idiocy as well like why does Atlassian have its own font and why can't they make it so it isn't fuzzy? Why can't my bank make a PDF that doesn't need the latest version of Acrobat to display? Oh they put style over contend and don't put their magic font in the file.

Internet Society CEO: Most people don't care about the .org sell-off – and nothing short of a court order will stop it

Re: Spare a thought for the struggling Private Equity companies.....

I think they did figure out how to buy souls. Nearly every retirement fund in the world is now competing with these poor struggling Private Equity firms and many of the retirement funds are constrained in just what they can buy with their money. Two decades ago one of the larger US funds had about a billion a week (and 4 times that once a month) that was to be invested in "high tech" but there just wasn't enough shares to go around so the stock price of the tech companies went to insane levels and everyone was happy to watch the pyramid scheme until the bubble burst. A few friends noticed that at the end of their weekly investment cycle the retirement funds would buy things that weren't such a good deal but we couldn't predict which well enough to make use of it.

When the retirement funds have to start pullout cash over the next decade, I expect the Private Equity firms will be there with deals implying that the retirees have already sold their souls.

ROI?

A revision from my last attempt at this...

So a billion dollars for about 10 million DNS records. The operation of that database should cost about $600,000 a year (figure $.06 cost per record which is high). Put another way, about $100 for every .org domain now needs to go to pay back the investment which is about $333 per non-squater. Figure in inflation and the price of the .org domains are going to go way up.

One man's mistake, missing backups and complete reboot: The tale of Europe's Galileo satellites going dark

The lovely problem of a complex problem

One of the great issues of any GPS system is you don't know exactly where anything is at any given time. You know were it was and you can predict where it is going to be but its only a very good guess. The satellites are being tracked but there is a delay between signal tracking them and getting the info into a computer half a continent away. The weather is going to delay signals in odd ways that usually allows compensation using different frequencies but only some times. The clocks are ticking away with some very high degree of accuracy yet subject to all the oddness that relativity in a gravity well has to offer. The ground stations are busy floating on land that is cruising in different directions at a few cm a year which was considered slow and stable until better GPS systems showed drift rate can vary over the months yet maintain a rock solid annual average. Yet in all that chaos, my phone still can display a map of where it is down to a few meters. I guess this problem demonstrated just how related the chaos of all guesses can be.

We, Wall, we, Wall, Raku: Perl creator blesses new name for version 6 of text-wrangling lingo

The perl 6 issue has caused much confusion and is limiting future adoption of perl.

Out of all the languages we use, perl 5 is the clear winner in dollars profit per line of code, lines of code needing changes per year and feature set per line of code. Some of the other languages have maintenance costs that are more than 4 times maintenance cost of the perl code base.

Raku has some very interesting concepts and I recommend watching one of Damian Conway's talks about its advanced features.

When I first saw Randall Munroe's "Million, Billion, Trillion" on xkcd it started me thinking about how true his hypothesis was so I've been running tests on the theory. I'm assuming the subjects are all consenting adults but I'm not going to ask them if I can play with their brains as it would bias the experiment. It turns out that most people don't understand large numbers at all and this is especially true if they happen to be a politician or board member and there seems to be an inverse relationship between understanding large numbers and how successful they are in their field of endeavor which doesn't do much to give me hope for humanity or reasonable future tax bills.

Re: Telegrams. In 1987 ?

Telegraphs are still used control some equipment inside expensive containment areas like matter colliders and reactor containment vessels.

The guy who created the system needed to talk to devices using one wire (as each additional wire could cost upwards of a million dollars to install), and was a amateur radio operator who knew Morse code. His idea was to use Morse code to talk to the equipment inside much like a serial port was used at the time. His boss insisted that he apply for a patent on the concept and after the patent office had correctly rejected most of the claims as being obvious, all he was left with was a patent for the telegraph just like the system used 100 years before.

Experts: No need to worry about Europe's navigation sats going dark for days. Also: What the hell is going on with those satellites?!

Dodgy ephemeris?

It looks like the sats might be sending bad ephemeris. GPS systems send a pulse out like "at the sound of the tone it will be "xx:xx:xx.0000000000". They also send out rough position info on all the other sats which allows a receiver to get a rough position. Once it has a rough position, then it uses speed of light to set its clock better and use that to gauge the difference between each sat and itself. It then will use the ephemeris data to get a precise idea of where the sat is and how fast its moving. That data includes atmosphere model hints as well as calculations for orbital wobble. For those who want to play at home, they are something like 12th order 3d polar coordinate polynomials. They include factors that change the wobble because of things like the Moons gravity as well as factors for Saturn and Jupiter. If there is a problem with the wobble model or the atmosphere model, these sorts of problems will show up.
