Unless something new happened that I'm unaware of, it was more like "the people of Reddit made some noise in an AMA, and AMD basically said "we'll look in to it"".

I think things are still progressing. In fact, it looks like they just recently hired someone to work on the Linux display stack: https://www.phoronix.com/scan.php?page=news_item&px=Valve-Hi... I believe they also hired

Thanks! I didn't know the APU supported ECC as well.

It has sort of been that way in the past, so I wouldn't be surprised if there were similar issues with Ryzen at first. However, I expect that there will eventually be some workstation grade motherboards from vendors like Supermicro whi

Ryzen does support ECC. Confirmed by the CEO of AMD in the Reddit AMA. https://www.reddit.com/r/Amd/comments/5x4hxu/we_are_amd_crea...

How could Nvidia really shut them down? It seems like they're just selling PCIe switches. I could be missing something, but I don't see anything even remotely infringing about this.

by Unklejoe 10y ago
A somewhat related question: Do PCIe switches know the address windows of their children? Meaning that when one child does an access to one of its peers (another child), the packet is sent directly to the other child rather than all the way

...yet a large number of people here seem to support a UBI. I'm not saying I agree with wasting money, but I feel like this very same argument usually gets shunned when it comes up in UBI debates. Maybe shunned isn't the right wor

Based on my conversations with friends who were/are addicted, that seems about right. After stopping long term opiate use, your sensitivity seems amplified. That's why addicts who can't get their fix are often seen scratching

> "I mostly use my Xbox controllers..." I feel like I should give MS some credit for the Xbox One controller. It's a very high quality controller, IMO. - It doesn't flex or make any creaking noises when you're sq

True. My exotic workaround was to buy rechargeable AA batteries from the pharmacy. If you buy a 4 pack, you can have a pipeline of always-charged batteries.

I haven't used the Steam controller, but when someone talks about a controller feeling cheap, I assume that they're referring to "creaking" under stress, lack of rubber stops on the triggers (i.e., when you press it all

Assuming that they're implicitly comparing Sweden to the US, I would like clarification on how Sweden is less business-friendly. From my quick search, it seems like their corporate tax is around 17% lower than that of the US. Perhaps t

I wouldn’t expect a catalytic converter to go bad during the lifetime of any car made in the last 10 years or so. That’s right around the time when manufactures started using wideband o2 sensors, which should help prevent one of the more co

As for the new cable business, is there a way for the devices to detect the version of the cable (maybe resistor strapping or something)? The reason I ask is because HDMI cables are passive, so any cable with all of the pins populated shoul

Agreed. However, I believe that in C, standard variable types are assumed to not have such side effects on a read, which is why such variables must be explicitly declared as "volatile".

Two things: 1. What's the proper way to do a NULL check? In the first example, they show how a NULL check could be optimized away, but I didn't see where they explained how to do it the right way. I might have just missed it thoug

by Unklejoe 10y ago
Does this actually count as a side effect? I didn't think that dereferencing a variable could ever be the sole cause of a side effect. I thought that side effects were only relevant in the context of a store (except for maybe volatile

Does this same idea apply when running ZFS on top of the Linux LUKS mapper (whatever the proper terminology is)?

Wait, there was no memory protection in Windows 98? Did it implement virtual memory for processes? If so, it seems like memory protection would be a freebie at that point? I was also unaware that it was not a pre-emptive multitasking system

It’s going to be interesting watching how local police departments and municipalities handle the widespread adoption of autonomous vehicles. In my town (a suburban town with a low crime rate), the police spend the majority of their time enf

Agreed. This is exactly why I hate driving behind SUVs. I like to be able to see the car in front of the car in front of me. It gives some additional reaction time.

Just curious: Is it possible to stay on an old release forever with an iPhone, or do they force the upgrade eventually?

Thanks. Lots of good information there. As for disabling interrupts on all cores, the specific case which I was thinking of was when you’re running a preemptive OS and you have a bunch of threads (== num CPUs) which all need to temporarily

There's a slight difference between rolling your own spinlocks and simply doing something like a CAS loop to change a variable. They’re usually both built using similar atomic primitives, but… The difference is that in a true lockless

Hmm. Interesting. I would have never thought to use that within a program during runtime. I don't think that the IRQ affinity facility is meant to be used like that ("that" being the masking of interrupts for a given CPU to c

At least the IEEE 1588-2008 (PTPv2) protocol uses TAI time (with the POSIX epoch). The current UTC offset is then passed in the Announce messages (as well as some flags for indicating an upcoming leapsecond) which allows the slave to derive
