The Cherry is lighter than the speakers, but will darken quickly next to the window. I have a vented front plate coming for the top space. The cooling fan sits in that space, and is really quiet.

Hey,.. It's not like Summit has slipped to the bottom of the charts! You're still working on the peak of the Mt. Geekdom as far as I'm concerned. All hail Grawk!

That ARM system is a beast, and it’s good someone other than Cray or IBM is at the top, honestly. Keeps them on their toes. I’m hopeful that I can continue to be employed working on summit for a few more years at least, and maybe stick around long enough for whatever the next wave of HPC will be.

You prefer it when Microsoft steals your data?

Had a arborist come out to quote on trimming some of our trees. I think this may get expensive.

Socially Distant, post Costco, In N Out

After reading the article I linked above and as the dust has begun to settle, I've gone from "I'll wait and see" to " I can't wait to see". I'm very optimistic about the future of computing. Of course, the next few years will be bumpy particularly for developers (can you say job security?) but I'm hopeful that this move may lead to some real advancements.

Very nice Steve. You should definitely send pictures of the finished unit to Parasound.

Not that it's directly applicable but it's funny that this was announced on 6/22,.. Sorry Dan. Japan Captures Top500 Crown FRANKFURT, Germany; BERKELEY, Calif.; and KNOXVILLE, Tenn.—The 55th edition of the TOP500 saw some significant additions to the list, spearheaded by a new number one system from Japan. The latest rankings also reflect a steady growth in aggregate performance and power efficiency. The new top system, Fugaku, turned in a High Performance Linpack (HPL) result of 415.5 petaflops, besting the now second-place Summit system by a factor of 2.8x. Fugaku, is powered by Fujitsu’s 48-core A64FX SoC, becoming the first number one system on the list to be powered by ARM processors. In single or further reduced precision, which are often used in machine learning and AI applications, Fugaku’s peak performance is over 1,000 petaflops (1 exaflops). The new system is installed at RIKEN Center for Computational Science (R-CCS) in Kobe, Japan. Number two on the list is Summit, an IBM-built supercomputer that delivers 148.8 petaflops on HPL. The system has 4,356 nodes, each equipped with two 22-core Power9 CPUs, and six NVIDIA Tesla V100 GPUs. The nodes are connected with a Mellanox dual-rail EDR InfiniBand network. Summit is running at Oak Ridge National Laboratory (ORNL) in Tennessee and remains the fastest supercomputer in the US. https://www.top500.org/news/japan-captures-top500-crown-arm-powered-supercomputer/

They'll probably bungle it.

Dirty Mind – Prince

My PC has been randomly waking from sleep since last summer. It's usually plugged into a power outlet, so it's not a huge deal, but it's disturbing that the problem hasn't been fixed in almost a year. Microsoft has also released Edge as a macOS browser. I've been using it since last week and it's been pretty decent. I upgraded to Chromium Edge on Windows a few months ago but I don't use it very often. Yesterday, I logged into my Boot Camp Windows 7 for the first time in a few weeks and noticed that Microsoft was recommending the Edge browser in Windows Update (official support for Win7 ended in January). Better than Internet Explorer 11, I guess. And they're trying to ram an urgent security update this week to machines via the Microsoft Store, which nobody uses: https://arstechnica.com/information-technology/2020/07/unscheduled-fixes-for-critical-windows-flaws-delivered-through-rare-channel/

With 2004 I was having a lot of problems with the display driver crashing when I clicked the start menu (screen goes black for a couple seconds), and occasional random full system crashes when playing games. I couldn't nail down a solution to it besides reverting to 1909.

I am on rev 1909 and I’ve been happy with it. You’re right to be concerned about Microsoft upgrades lately. I’m using the beta version of Edge which is a chromium-based browser. I’ve been very happy with this browser. It works for all sites that I’ve used it for. I’m also happy that Google isn’t stealing my data.

That's really damn nice Steve. I'm really digging the matching aesthetic.

(Rant warning. Also, I haven't been reading any of the Apple commentariat, so I'm sure this has been covered and perhaps refuted by other people in more detail.) I'm pessimistic about this move to "Apple Silicon". Remember all the "G5, the only desktop supercomputer" nonsense from the early 2000s? Where some cherry-picked works-in-the-lab-only benchmark showed it outperforming an Intel chip, but ran everything in the real world with all the speed of frozen molasses? I'm getting echoes of the same thing here. CPU design is a game of dollars spent on chip design and optimization. Intel makes fast CPUs because it has been dumping the largest sums of money into the problem for the longest period of time. Because of this, its (crappy) microarchitecture has outran and outperformed better designs like SPARC, MIPS, PA-RISC, Transmeta Crusoe, and (especially painful to me) the superb DEC Alpha. This means Intel is the only game in town for high performance. "Lightroom ran smoothly" — yeah, that's convincing. This move is going to be a huge pain in the ass. It'll be fine for Mac users who use nothing more sophisticated than Safari and Apple Mail (those who haven't already moved to an iPad for those tasks). For the minority of us who actually use Macs to do complex things? lol. Binary compatibility will suck (no vector instructions according to the article linked above). Updating all the open-source compilers will suck (will Apple contribute changes back to LLVM upstream? no clue). A bunch of libraries will probably stop being good (I expect low-level optimized linear algebra tools to have problems). I'm already holding on to 2015 MBP because I dislike the new hardware, and running Mojave because I want nothing to do with Catalina, and dread the day that machine stops working. I think this move is to make it easier to develop i(Pad)OS apps. That way apps are developed on nearly the same hardware that they will run on, and Apple really only needs the Mac as a development platform for its mobile devices.

Happy Birthday Cristal Creg!

Happy Birthday Kreg!

Happy Birthday Crek. Any relation to that Velo Fellow? Have a great one!

Happy Birthday, only the best for you, Creg!

Happy Birthday, Greg!

Happy birthday, fellow oneophile!

Is Creg related to Graeme? Happy birthday Greg Snakebane! Hope you are bathed in wine on your big day. Cheers!

I wonder how MAGA rallies sounded on that system?

Like many people here, I use the hospital grade cords... They work great.

Buy audio components with competently designed power supplies. A $3 inductor does way more than any of these cables or conditioners.

Second coat of finish. I still have rack rails to install, to hold the gear. The holes are vents, which will get black mesh behind them.

Bohlander-Graebner ribbon super tweeters and Dayton Audio full range drivers, both from Parts Express. Luvdunhill did all the calculations for interior volume, port and he built the crossovers. They sound amazing! I liked the way I grooved the Cherry baffles, so decided to make the new rack a similar look. There's a little more about the speaker build on pages 13 and 14 of this thread.

RIP - Hugh Downs, dies at 99

Thank you, all you wild and crazies! Did a little hiking and a little driving today. Believe it or not I passed on any wine today but that oversight will be rectified this weekend.

Electric fuel pump. Fortunately I didn't have to drop the tank, but I did have to take out the entire back seat and trunk liner, then work through an access hole that some galaxy brain at GM made about half an inch too small for the pump and locking ring to fit through.
