As Corona viruses tend to mutate rather quickly, it is noteworthy that the level of immunity achieved this way is MUCH higher than that of a potential vaccine. These people are, henceforward, immune to this disease; they can't spread it either.

I don't mind it. The code was pretty tight on the 68k.

This can be easily explained

Back in the days when the Amiga was designed, CPUs didn't have a "memory management unit".

Today, every program gets its own virtual address space. Therefore, every program can pretend that it is located at a fixed address. It cannot access the address space of other programs (processes). They themselves can believe to be located at the exact same address and it doesn't matter as they don't interfere.

In order for programs to work together in a multi-tasking environment, unlike DOS where only one program could run at a time, they had to be "pc-relative". "pc" stands for program counter. It's a register of the processor that determines the position of the current instruction. When your program got loaded and executed, you had to access your data relatively to the program counter (that is, relatively to where in the address space your program was loaded into).

Say, your program's start address was at 0x0000. Say the data was located at 0x0100. Now, if your program was loaded into address 0x2000, then your data was located at 0x2100 (for simplicity I used 16-bit addresses, though the 68k used 32-bit).

By accessing your data relatively to the pc-register, your programs became independent of the memory locations they were loaded into.

Some idiots never managed to program properly. Their programs were always accessing fixed addresses (most demos, for instance). If there was something else at those addresses - boom!

As has already been previously stated, the SCSI implementation was broken. Likely, some idiot forgot a fixed address somewhere. By running the clock first, you allocated a certain address space, guaranteeing that whatever came afterwards was pushed further up in memory.

I feel the obligation to tell the people that ZFS is only useful on dedicated file-servers (as Ubuntu is unlikely to be used for those). Some people read the specs and decide to run ZFS on their desktop systems. That is stupid in many ways. Do yourself the favor and don't.

On closer inspection, these accusations all fall apart!

> Other allegations include a Huawei staffer creeping around a trade show in the middle of night and removing covers from networking gear in order to photograph the circuitry inside.

This sounds like something to someone who doesn't have a clue of today's technology. It would have worked in the 70's or 80's, maybe. Today, those circuits come on boards with several layers. A photograph from the top, typically, doesn't give you much.

> Another engineer is accused of sneaking into a rival firm’s lab in order to pinch a robot arm used for testing mobile phones. The robo-arm was measured and photographed before being returned, the US claims.

This is the old Telekom accusation. A German tech-media site (Heise) commented on this, that they had built such a device themselves with little trouble. Students can do this in a few days. The accusations are ridiculous.

For those who don't know GERMany that well

The BND is just a GERMan speaking CIA outlet. They helped them to start the war against Iraq, by torturing an Iraqi until he told the lie they want him to tell (see: “Curveball”). They started the war in Sudan for the US, by delivering tanks and other weapons to both sides - “rebels” and government (see: “We’re Going to Take out 7 Countries in 5 Years: Iraq, Syria, Lebanon, Libya, Somalia, Sudan & Iran”). They have been spying on their own (strongly forbidden) for the US. All to no avail.

So this is why Huawei is so evil, eh?

Hardware specs do matter as well

Another reason being the old hardware's specs, of course. A device with 8 cores, 8 GB of RAM and 256 GB flash (hard disk), would have been considered a mainframe not so long ago.

It has become hard to slow down such machines. Even the most inefficient of software rarely manages to hog so much RAM or processing power. Therefore, you can safely keep the old, as there's not much of a difference anyhow. ;-)

When will we get rid of this malady?

That's the real culprit:

> execle("/bin/sh", "/bin/sh", "-c", mda_command, (char *)NULL, mda_environ);

The issue here is "the typical Unix problem": Programs are starting other programs to do things. The correct approach would be putting the code in libraries. The shell commands would then only be handling the command-line options, passing them on to the library. Programs could use the libraries "as part of their code". This is the safe way. This is the efficient way. But they never learn...

Reporting bugs and adding code? Don't bother!

If you are thinking about reporting bugs and adding code – don't.

I did report several bugs, sometimes proposing fixes. I got insulted, and even bugs marked as critical, which would cause the entire QtCreator installation to become unusable, were ultimately ignored.

I don't know what is going on there. They have too little personnel? They might have overstretched (3D and whatnot)? They might have issues with getting enough cash in? I don't know. All I know is that the people there appear to be stressed “beyond repair” and they pass this on whenever you get in contact with them.

I dropped Qt a while ago when I noticed that things were only getting worse instead of better (i.e.: I found the bugs in their code mostly and thus couldn't repair things. I found myself avoiding Qt functionality wherever possible and using it for the GUI only. This increasingly sucked, though.).

As much as I hate MD, there are two sides to it. You can safely assume that for every “coffee burn victim” there are thousands of people complaining that their coffee was too cold, as it cools down relatively fast and many prefer to drink it REALLY hot.

Hence, this is the typical situation, where you just can't do it right.

Just never go to Italy, Greece, Turkey or any other place. Here, we are using Celsius for the temperature. 100°C is the temperature of boiling water. There's a reason for that: Water can't get any hotter, else it evaporates. ;-)

Coffee is served hot. Tea is served hot. So are many other things. It's left up to you to leave it for cooling. They don't serve hot stuff to little children, though. Maybe there's your angle...
