VulgarandStupid posted:I've been out of the cell phone game for a while. How many phone models come with the charging circuit built in, just requiring you to buy the charger? I remember the Bionic offered a different back cover which was a little thicker and wouldn't fit in any cases, and combined with the charger it was around $100. Awful, just awful. But you're right, the technology should be much more wide spread. I don't think I'll be willing to buy another mobile device without Qi charging. gently caress cables.

EdEddnEddy posted:That is one of the worst things HDTV's have brought out in years. I believe the only time it is semi good is when watching Sports, but movies are just destroyed by it, and it looks the worst when you watch a Animation either drawn Disney like stuff, or 3D Pixar content. Both are impossible to watch as the blending just does not work in fast movement scenes and such. I don't think you can blame HDTV for that. Later SD CRT televisions already supported 100/120Hz and they created extra frames by interpolation.

Paul MaudDib posted:I bought into 16 GB two years ago and I wouldn't feel bad about 32 GB now for a gaming or workstation build. That's like another $100 on top of your build, which is minimal relative to the chance of future-proofing. On the other hand future-proofing RAM is silly since it's the most easy upgrade you can do on a computer as long as you haven't filled all the slots. Fill half of the slots and then buy more when you need it or when the price of the DIMMs stops dropping. It would be more worthwhile to put that money on a bigger SSD, which is a bit annoying to upgrade.

DrDork posted:Yeah, but those are also specially designed systems where the board layout, heatsink, fans, and chassis are all explicitly designed to work together to provide the proper ducting and airflow to make it all work. If you ripped the heatsink out of that 1U setup and just dropped it onto a normal ATX board and case, it would not fare well at all. True, but if you provide enough airflow for the case so that the temperature inside doesn't rise too much, then the 4000 RPM fan on the Dynatron will be able to keep the CPU cooled. Certainly not an ideal solution.

MaxxBot posted:Prime95 uses FFTs to implement large integer multiplication and FFTs are used in a wide variety of scientific and engineering applications. So basically you can use Prime95 to test your overclocking in a situation where you would not be overclocking. A while ago I read a comment that you shouldn't use P95 to test your OC and I understood the argument in the way, that if you limit your OC to where Prime95 is stable you will not get full power out of your CPU. You can OC to a degree where P95 is crashing or causing the CPU to thermal throttle, but games or anything else you do would still work perfectly at that stage.

Ak Gara posted:That sounds like a good idea. After trying stock cpu usage was 10% Getting rid of any problematic mods is the correct solution, but what is your fundamental problem? Is the problem that Minecraft is running slow even when using all of the CPU, or is the problem that your other programs are running slow because MC is hogging all the CPU? If the problem is the latter you may mitigate it by going to Task Manager and configure process affinity for Minecraft process, so that is only allowed to use 2 or 3 cores of your CPU.

I think the only people I know of that are buying physical media are all over the age of 50 (still a large group of consumers with disposable income, but they're declining by definition) or hipsters specifically for LPs. Otherwise, people with kids may be using digital downloads instead. Earlier this year I decided to finally finish watching Buffy. I watched few eps on Netflix and then I decided to compare the picture quality to the DVD collection I also owned. And the DVDs had superior quality and 16:9 widescreen format compared to the dim and dark 4:3 format on Netlix, probably close in quality to the original TV broadcasts. Supposedly Joss Whedon considers that the correct and true way to watch Buffy, but I'll have none of that.

DrDork posted:I thought one of the benefits of the latest few classes of TB optical cables was massively increased durability compared to traditional fiber? Some of Corning's stuff advertises "zero bend" cabling and basically says you can tie the stuff in knots without ill effect. I mean, I'd imagine it's never going to be as durable as anything copper (unless you throw a pretty hefty jacket around it), but it would seem the current stuff puts the most likely point of failure back on the connector bits rather than the bulk cable itself. The Linus Tech Tips "optically cabled VR headset" video does indicate that optical cable can be quite durable.

bobfather posted:I also lolled often because the SP firmware updates would be delivered by Windows Update. It never happened to me, but I always wondered if the computer would ever force a reboot to install updates, start installing a firmware update automatically, and then have the install fail, bricking the device. I have never owned any computer that had automatic firmware updates, and while I'm aware that in the days of UEFI firmware updates are a lot less scary, I've been using computers for long enough that "hold your breath" is a common practice for firmware updates of all kinds. I know a guy who experienced something like this. He was doing a test install of Win10 on a system with and SDI card. The driver install for the card also updated the firmware. At 80% of the reflash Win10 BSODed, resulting with a bricked $1000 SDI card.

My first PC was 286, but the first computer I bought myself was a 386. I bought a used set of 386 CPU, motherboard and RAM and installed them in the 286. This was sometime after 1995, so I was 10+ years behind PC evolution at that point.

I would just reinstall it, but i'm a bit worried about having to re-register my installation since I don't remember where I kept the key (and I might've used it to register the boot camp installation on my macbook...) You probably would have needed to re-register it anyway, with such a significant hardware change. Just buy cheap Win 7/8 OEM keys from eBay or SA Mart and forget about this worry. I registered my Win 10 with £5 Win 7 Pro key I bought from eBay.

We just received couple HPE Proliant servers with Xeon Gold 6146 processors which took almost month and a half to deliver. Initial estimate for the processors was 60 days. I just ordered another server. On the original configuration the CPU had normal delivery time, but the 64GB RAM sticks had 60 days. I don't know what RAM shortage we are suffering now. Fortunately we could swap it to different similar model with usual delivery time.

I'm surprised there hasn't been talk of the Intel's new Xeon R-line processors, their weird subterfuge to avoid dropping CPU prices. Feels like they are finally starting to feel pressure from AMD. We were planning to purchase new server and Xeon Gold 6248 was the prime candidate, when we noticed the 6248R for slightly lower price. But instead of a cheaper 6248, the new processor is more like a rebranded Platinum 8268, twice the price of 6248.

Friend recently complained how his son had broken the USB-port on his cellphone and he really wasn't interested on paying 69€ for the repair on a 200€ phone, and he was even less interested on doing the work himself. Those ports don't fail often, but I bet the expenses of a single failed port would cover the wireless charging resources for a whole lot of people.

Paul MaudDib posted:yeah it's the one thing I don't like about my Noctua cooler, is that larger cards sit so close that you can't hit the slot release without taking a knife and shoving it down there. A quick-release button that doesn't sit under the GPU is a very tidy solution to that. Things worked fine, because all the motherboards were horizontal, all the add in cards were small and light, and the big and heavy cards were all long enough that they attached to the rails at the front of the case. I'm sure the AGP people wouldn't have specified such an extra expense and annoyance if they hadn't found it necessary in testing. You might think the screwing the bracket would be enough, but I don't think the manufacturing quality of cases is high enough to rely on that. I used to have a case where you couldn't fasten the GPU once it was locked in the slot, the bracket notch and slot screw hole were way too misaligned. I had to put the screw on the hole below bracket.

BobHoward posted:You're way too confident that this would work well in practice. Linus Torvalds himself is well aware of the idea, and has dismissed it. The standard CPUID query could only return the features that are common for all cores. If an application wants to use the fancy features it should do a special query to return a per-core feature set and be required to tell the scheduler which cores the thread is allowed to use.

That's probably the efficiency gain for PSUs that really matter. As napkin math let's assume 200 million business desktops worldwide that are always on mostly idling, so that 4w would total to about 7 TWh savings per year, about a half a nuclear plant.

PC LOAD LETTER posted:Sure but I don't see how that works in favor of Intel's approach here (they'd have to significantly drive down costs of their Xeon money maker while still having the accelerators on die anyways while Genoa eats their lunch) and I don't see how it'll drive adoption of these accelerators either which will greatly diminish their practical value in the market place. If the premise is that there are some features that only few customers want, then there are several scenarios how Intel could handle it. 1. They could manufacture different hardware SKUs, but this would cause unwanted expenses. Most CPUs wouldn't have the features, small portion would feature A, another B, and a tiny portion both A and B. 2. They could only only manufacture full featured CPUs. This would force most customers to overpay for features they don't want, and the few customers that want them would get the CPUs cheaper than they are worth. 3. They can hardware disable the features. This way they can build a single product, but sell it a different prices to customers. 4. They can software disable the features. Similar situation to the previous, but if you get a new version of the software that could benefit from the feature youcan then license it instead of buying new hardware. This would significantly improve the chances the feature would achieve wider use.

priznat posted:The things that really don’t make sense to me are the tri mode raid controllers where people are plugging nvme drives into it. Is there really any benefit? Do people really want to run RAID on nvme in tyool 2023?? This honestly seems like a scam to me for people selling enterprise hardware to people who don’t know any better. At work we'll probably end up with that until RHEL starts supporting ZFS. And even then it will probably take some convincing that ZFS is better than battery backed write cache. It probably limits them quite a bit, but I would assume NVMe behind RAID is still much faster than SAS.

True, enterprise NVMe should have battery, and I think some of them actually have them, if not all. I think flash could end up in bad shape if it loses power suddenly. I think RAID-cards nowadays mostly have flash-backed write cache. A stick of RAM, flash storage and enough capacitor to write the RAM contents to flash in power outage.

in a well actually posted:ZFS on nvme is fine, but kinda underwhelming. A design around spinning rust doesn’t really drive a billion low latency iops well. Yeah, or if Red Hat and Oracle make some kind of deal. But then I remember how Red Hat suddenly purged Oracle Java from their distros. So not much hope for ZFS with us, we are loathe to use anything besides vanilla kernel. We mostly use HPE ProLiant servers and we don't even use drivers from HPE, except in one server where the kernel RAID driver kept crashing for some reason. But that hasn't been without issues either, one time I updated to the latest smartpqi and the RAID ran so slow it caused an outage for the service and we had to revert to the old version. Haven't dared to upgrade again.

BurritoJustice posted:I honestly don't see the issue with unlockable CPUs. The alternative is the situation right now, where they just permanently fuse off the features instead without the option of upgrading in place. I definitely agree with this. We are currently considering upgrading the CPU on an older server. The server is working perfectly fine, but people want to use it with a software that requires significantly more cores. Upgrading the CPU or replacing the server are both options with annoying expense and hassle.
