It is indeed a huge problem of Java, that it often makes it difficult to avoid generating garbage. However, one still can reduce it a lot if trying hard. And be it by reimplementing selected parts of the standard libraries. But the job of a

Very different systems. First of all, the Tesla Autopilot is not full self driving. The Autopilot is an assistant system combining distance aware cruise control with lane keeping (autosteer) and lane changing. It always requires full driver

Only in a very limited way. As we move forward, we are quickly reaching the point where for more and more time, renewables can carry the whole grid load alone. Nuclear power plants would have to be switched off in those times. And while the

It seems the technical problems are resolved and currently the data is no longer "estimated". 3% of the consumption comes from wind, and 17% from solar, which isn't to bad. While the UK certainly isn't the optimal place

The huge problem with nuclear vs. natural gas is, that nuclear power plants have only a limited range, in which the power output can be regulated and they are not too quick in that either. So you need something else you can power switch qui

I think "estimated" is a recent addition they show, when the input data sources fail. Which unfortunately they do quite often. But then, I am not paying for the service, so who am I to complain? :) When values are non-estimated,

No, they are currently not subsidized at all. What was done was guaranteeing minimum prices for renewable energy. These prices used to be way higher than market prices to make renewable energy generation economically feasible. This way espe

Right, the detection of obstacles needs to work perfectly. This is where LIDAR is good at, it gives pretty precise 3D information about your immediate surroundings. Especially when comparing with high resolution maps, obstacle detection sho

It is the same as with any product on the market. The producing company is liable, if the product causes harm when used and it is the products fault that the harm was caused. For example if lets say a TV blows up during normal usage. This i

This is an important step. For the first time there is full self driving where the driver is no longer require to pay attention to what the car is doing. However, this is not a generic solution. This system is limited to a very narrow set o

Well, that is the catch: you can engage the system only on certain roads which also happen to have a divider between the traffic directions. So it is basically impossible to be facing an incoming truck there.

No, that was an earlier design. On later iMacs, the magnets were replaced with glue. So to perform any service on the machine, the repair shop has to cut through the glue and after the work glue the Mac back together. Which, for a desktop,
853.
by _ph_ 5y ago
Yes, its just between 100 and 200€ of service charge, as they have to unglue and glue back together the machine. And carrying an 27" iMac is also a challenge - you don't want to have it damaged in transport. This all is possible,

Obviously, dust settles on flat horizontal surfaces, so having an air intake at the very bottom isn't optimal there. And yes, if the Mac stands in an office with daily cleaning, there might not be much dust, but still, if you run it fo

My iMac once was super quiet, but many years later is less so. Unfortunately, I cannot clean its fans, which would probably reduce the noise levels quite a bit.

At minimum, Apple should be required to perform a cleaning for free. That would quickly ensure good accessibility. Equally, the cost for a keyboard exchange on a laptop should be capped at about 100€.

It is amazing, how much engineering goes into these machines - everything is designed from scratch for this form factor. It is also nice to see that the SSD are not soldered in place, though it isn't trivial to exchange them. The cooli

In professional environments, x86 really took over only in the mid-2000s, especially with the Opteron. Whether x86 ever took the performance crown is debatable, if you consider the big PowerPCs IBM still sells.

Of course the check sum would need to be distributed on a different path. A different site or just via Twitter.

Linux, or some Unix of the old times. Some EDA tools are still available on PowerPC (not sure about the state of Sparc).

Exciting news! While I am mainly a Mac user, Linux is the other operation system I use (usually via VM on the Mac) and the one alternative operating system I would use, if I would not have a Mac. Being able to boot into Linux directly adds

No, it is a reasonable category. There is a huge distiction between things, which don't work yet, but you know that you can make them work and have even a schedule for doing them. And there are things, where you either don't have

Right, but I would know it is code from the original author and not modified by anyone, who might gain access to the download server.

The point is not about running the code, it is about verifying you are running the code you intend to run. That is why I would prefer the instructions to be: download the code, compare against this checksum, then run it. The curl pipe thing

From earlier tweets by Hector I remember that virtualization is working and he was able to run Mac OS inside a VM on Linux.

Even more so: all Macs have pretty much the same hardware. From the Air to the Studio, the same CPU cores, the same GPU cores, same auxiliary hardware like neural net processors. All enhancements should pretty much affect all Macs running L

There are indeed some reasons, why it would be nice to have two JWST. Certainly, at least some costs would have been lower for building a second one. Though all the labor would have duplicated, and it seems a lot of labor went into just bui
