Submission + - AMD Releases it's Rome Second Generation EPYC CPUs (anandtech.com)

SolarAxix writes: Today, AMD released it's Rome Second Generation EPYC CPUs, the AMD EPYC 7001 & 7002 series. Was the hype real? According to Anandtech's review of the top of the line EPYC 7742 with 64 cores and 128 threads dual CPU system (for a total of 128 cores and 256 threads), it seems to be the case:

"...So has AMD done the unthinkable? Beaten Intel by such a large margin that there is no contest? For now, based on our preliminary testing, that is the case. The launch of AMD's second generation EPYC processors is nothing short of historic, beating the competition by a large margin in almost every metric: performance, performance per watt and performance per dollar.

Comment Re:Power consumption? (Score 5, Informative) 195

The team that runs the www.raspberrypi.org (now running on a cluster of Pi 4 in one of their two data centers) mentioned that idle is now 3W and peak is around 7W:

"The Raspberry Pi 4 is out. It’s a quad core ARM A72 running at 1.5Ghz with 4GB of RAM and native 1Gbps ethernet. This means that according to our benchmarks (PHP 7.3 and WordPress) it’s about 2.5x the speed of the 3B+, thanks to the much faster core design and slight clock speed boost. The downside is that it uses more power. Idle power consumption is up slightly to about 3W, peak is now around 7W, up from 5W. It has some improved video features too and USB3."

While they don't mention it, I don't think it would include the total power consumption if you have additional USB devices attached to it which could drive it to 15W (5v and 3 amps for a total of 15W).

@raymoris: The quote is accurate, just not from the source article you quoted, but from the second/last one in the post from NPR which is the original source: https://www.npr.org/sections/h...

The Slashdot story has 2 separate articles that covers the topic. One from Quarts and the other from NPR which was one of the sources used for the Quarts article.

The Quarts article quotes the NPR article, but it failed to include what @Nothingburger mentioned which I agree, makes for a misleading summary and should have been included, but does not change the fact that the paper has been retracted.

I would say it that with the additional analysis that was offered by study's main author that excluding the nonrandomized people, the results were the same would imply that the paper's conclusion could still stands, but will probably need to be resubmitted with the changes to be accepted since the original submitted paper does have some issues as-is due to the nonrandomized people being included in the results.

Comment The problem was not during the VSC, but before (Score 1) 123

The actual problem from a race strategy perspective was not during the VSC, but before. Hamilton could have been going faster during the race before the VSC, but since Mercedes software said he needed a 15 second gap in case of a VSC, he did not need to get closer to Vettel since Vettel was required to do a pitstop as per the requirement for 2 different tire types in a race (and the fact that he had not made any pitstops yet). Obviously this was not the case and he probably needed to be 10 second (or less) behind Vettel which Hamilton's car could have certainly done during the race prior to the VSC.

In the last few years, and even more so this year with the 3 engine limit for the year, it's a lot more about long-term management of the car and its key components (engine, gearbox, etc...) over 6-7 races so they don't go full-out during the race, but just "fast-enough" as to not get passed. In the end, it's this managing for the long-term that's cause Mercedes to take this approach (and why many might say is one of the main factors that the current F1 format is not interesting).

Comment What about older CPUs? (Score 0) 276

While I donâ(TM)t have specific numbers at hand, I would think that the majority of active computers with Intel CPUs contain CPUs that were released before 2015.

Intel should release a statement that would cover CPUs that have been released since 2010 (because itâ(TM)s a round number and would probably cover a good majority of system). Microsoftâ(TM)s statement seem to indicate a bigger penalty for older CPUs which Intelâ(TM)s does not cover.

Comment Re:20 cores DOES matter (Score 1) 167

If you run at stock speed, you are right.

If you have the right motherboard and the right CPU, you can get some pretty good overclock on these CPUs (if you are into overclocking). I've got a few X5650s setup at home. I can get 4.2 GHz on one and 4.6 GHz @1.34 volts on the other 24/7. With 6 cores (12 cores /w HT), water cooling is almost a requirement at these speeds (unless you are really lucky with the CPU). Max temps for both is ~75 C in a 20 C room. I got each CPUs on eBay for $60 a piece and I already had the MBs.

These days the most expensive part could be the X58 motherboard unless you already have one. Some of them are selling for more used than their new MSRP. One drawback is most X58 boards don't have USB3 or SATA3. You could always get PCIe cards for those, but the bill of material (BOM) would increase.

If anyone is interested, there's an Anandtech forum thread that has a lot of information on it: http://forums.anandtech.com/sh...

Comment Sometime software can help (Score 3, Informative) 95

There are some software solutions out there that in addition to actually store your writing, have functions that help to store your research, character bios, locations etc... Some are gear more towards writing novels and others can cover a wide gamut.

I've used Liquid Story Binder (which doesn't seem to be actively updated any more) and Scrivener. They both have ways to keep your facts straight.

You don't necessarily need to use software that's specifically created for this. I've also used mind mapping tools (Mindjet MindManager, MindGenius, FreeMind (open source)) when I am starting out with some ideas. Other tools that I have used includes MS OneNote (free), Evernote (on-line), AllMyNotes, Right Note, myBase and Ultra Recall.

Interestingly, even with access to these these tools, I still use Notepad++, or vi a lot of the time to store some info in txt files.

Even with any of these tools, you should always double check and use people to verify that you didn't mess up.

When I said what's different between the banks and Apple, it was about the process itself.

My bank keeps gets information on my credit card usage even though all the information is stored with VISA, Mastercard, AMEX, etc...

What is fundamentaly different from a patent perspective between what Apple pantented and what the banks do when it comes to targeted adds based on credit availability? I would say that the only differences would be that Apple would have external ads that are targeted based on a certain credit availability. Even then, I've see ads from afiliated 3rd parties from my bank for insurance companies whereas my son, who doesn't have a job and doesn't have a lot of money going into his account, does not see any of those ads. I would think that the targeted add has looked at our credit worthiness before showing specific ads.

But if you wanted to look at it from your perpective, Apple might become a bank in the future...

Comment How can this be a patent? (Score 5, Insightful) 133

From my perspective, there isn't anything truly innovative here. It's more like a business process that shouldn't be patentable. Banks already do some of this within their environments with targeted programs based on their customer's level of credit worthiness.

What's so different between the banks and Apple? Whereas banks only do it based on certain marketing programs, Apple would/could be doing it at a transaction level instead. That being said, they are very similar in concepts.

I think the bigger question is why can this be a patent?

From a high-level perspective, it's just a bunch of APIs that are integrated together to get the job done. Put in another way, if someone decides to integrate a set of APIs together, can that be patentable? Should we start to have a patent lawyer on speed-dial if we link different APIs together? Maybe we need to submit patent applications for our new API mashups before someone else or a corporation does it.

Comment Minecraft migration anyone? (Score 1) 525

Just putting it out there...

Who thinks that one of their marquee project will be migrating Minecraft (client and/or server) from Java to .NET? Until a multi-platform version of .NET comes out, they would be limiting themselves to migrate it to only one platform (I am not including Mono in this case).

(It might also help to motivate kids to have some exposure to .NET, but the bigger story would be all those systems running the "New" version of M$craft).

Comment Re:Worthless degrees (Score 1) 438

You over estimate the university degrees from India.

I am from India. I know what I'm talking about.
But for a few good schools like IIT, IIM, IISc, AIIMS, NITs etc rest of what passes for college education in India is nothing more than rote-memorization and regurgitation. Both the Physics Nobel laureates of Indian origin (Raman and Chandrasekhar) are alumna of the University of Madras. Today, that univ does not have a single math prof capable of correcting an answers in a Real Analysis examination. The syllabus specifically says, "Real Analysis, with theorems and proofs as stated in the book Real Analysis by Apostal". You deviate from the proof given in that book, the professors are incapable of checking whether it is right or wrong. It is a disgrace to call it a university.

This statement definitively helps me to understand a prof I had 12 years ago. In a data structures course, I kept getting F's or D's for my assignments and tests because I wasn't using the material from the book even though the work and answers were correct. The prof had just moved from India and it was the prof's first time teaching in North America. The prof. from India, after reviewing my work with another more senior professor that had been teaching for 10-15 years, switched my grades to B's and A's. At the time, I just though it was because the prof. didn't know Java (which might have also been the case). Instead, it appears to me that it was based on a common practice in some colleges in India.

Submission + - LogMeIn to discontinue free access with 1 day notice despite $190m in revenue (logmein.com)

An anonymous reader writes: The remote desktop service "LogMeIn" sent an email to its users today notifying them that "LogMeIn Free" will be discontinued — as of today. This is a major shock with minimal warning to the millions of users who have come to rely on their service made all the more surprising by the fact that "consensus revenue estimates for LogMeIn in 2014 are $190.3 million", suggesting that their system of providing both free and paid accounts for what is ultimately a straightforward service that could be duplicated for well under $1 million was already doing quite well.
