City of Ivrea has been named a UNESCO heritage because of Olivetti factories, offices and worker homes. I still own an Olivetti typewriter and an AT&T Olivetti UNIX PC, vintage 1987, which is still working and has a graphical user interface, although a primitive one. It runs UNIX version 7 and a LOGO interpreter. I have 30 5" 1/4 backup disks with my GCC compiled from Open Source but, since the first disk is not readable, I cannot install it. But the UNIX and LOGO ("from the Store") disks are still readable.

Greetings Grant,

Back in the 60s I built an AM tube type radio in high school in my electronics class. We called the tubes vacuum tubes. Is Valve a trade name or type of vacuum tube? I've never heard the tubes just called valves.

Thanks for any insight you may give. :)

Tubes (Vacuum tubes) were generally known as Valves (Thermionic valves) in most of the rest of the world.

Physicists who used valves for they instruments were called "valvolisti" in Italy. When I started using germanium transistors in 1959 to rebuild the "contatori di dieci" on a bubble chamber made to detect neutrons, one of them told me "this stuff has no future".

Really killer deal going on this holiday for a EVGA GTX 1080Ti + Hydro Copper Waterblock for $760. That is $100 off the normal price for the card alone with the $170 Hydro Copper water block tossed in as a bonus. So anyone who already has a custom loop or considering building one should really consider the offer.

A lot was made of the Titan V when it was released as being the most powerful gaming video card ever made. But the fact is, it was made for scientific applications, being the best thing even for games was just a by-product of that.

AnandTech have just posted an article that looks at the Titan V- it's architecture, and what it was built do. And they have done some benchmarking based on what it was actually built for- Artificial Intelligence, Machine Learning and Deep Learning.
And it's performance, under the right conditions is impressive. For a given task that can't make use of the Tensor cores, it's performance is up to 1TFLOPs. For the same task that can make use of the Tensor cores, it's performance can exceed 90 TFLOPs.

I can't think of valves without dragging out my old, very old ca. 1910 Electrical Engineer's Pocket-Book by Horatio A Foster. It has a section on Telegraphy with a 9 page sub section on 'Wireless Telegraphy'. It goes into discussions as to how signals are propagated from spark-gaps and, using a device referred to as an 'coherer', detect the presence of oscillations. The last page of this sub section discusses 'Hot-Filament Detectors'.

"Another type of detector owes its existence to the peculiar properties of an incandescent body when placed in a rarefied gas. Under such conditions the incandescent body emits negatively charged corpuscles, or electrons, which are free to move about in the rarefied gas, thus rendering it a more or less good conductor. If, for example, an incandescent lamp filament be mounted in its exhausted bulb in close proximity to a plate of metal connected to a third terminal, and a battery be connected between this terminal and one of the terminals of the filament, a current will flow from the battery through the gas."

Any time I'm feeling old, I pull this out and realize how young I really am.

P.S. In 1978 I took a test as part of an interview to work at Texas Instruments in Dallas. One of the questions was to solve the voltages around a valve. I started to blow off that question until I realized the valve was reversed biased, non conducting. The question could be answered by putting your thumb over the valve as a static network. The interviewer's had never had anyone answer that question and were shocked by my correctly answering it. -j

For those in need of high capacity, very fast storage this sort of drive will be of great use (at least until Xpoint devices become considerably more affordable, or motherboards support more than just 1 or 2 M.2 drives).
2 and 4 M.2 SSD devices on PCIE*3 riser cards.
Unfortunately no word on pricing or availability.

New Noctua fans capable of both high static pressure & high air flow.
With a bit of luck their price should improve after a while.

I just forked over a small fortune for six of them for my dual 360mm rads. Will see whether they improve what I have on there now. The low fpi rad with little restriction should pose no issues for the lower static pressure than what would be possible with the NF-F12 IPPC 2000 fans. I have those also on another machine. A really great fan though noisy. Three of the new Noctua's are replacing the standard NF-F12 fans. If am to believe Noctua's P-Q graph literature, they are supposed to work better than the NF-F12. What will be the harder test is the high fpi/high restriction rad. That has the stock XSPC Xinruilian 120mm 1650 RPM fans on it.

I've been looking at these, too....considering them for my new build. Only downside is they're just as ugly as the old ones. And no bling whatsoever...
But please report on your findings ? Have you tried EK's Vardar fans ?

One of the best things about them.

I'm very happy with the ML140s I used to replace the original front case fans in my Obsidian 750D Airflow edition case.
They are noisier, but they also shift a lot more air.
And not an LED in sight.

In my opinion, the industry has gone WAY overboard on the 'BLING'. What good is it for? Bragging rights that: "My PC puts out more colored light than yours. Got your sunglasses?"? That's about it. It has absolutely no improvement value in the operation of the PC.

And I found out (fortunately in time) that the software used to control the 'BLING' has the potential to brick a PC. I just built this PC a few months ago and would have hated for it to get bricked by the software from ASUS (the manufacturer of my motherboard). Fortunately the 'BLING' can be disabled in the BIOS, at least for motherboards.

I'll bet that the Kitty man, Mark, has no 'BLING' on any of his PCs, not by choice anyway. :)

Ghia, the 'BLING' has no value IMHO. Just thought I would point that out. :)

Have a great day! :)

This I know. And I don't have any bling here either. What I WOULD like is some discrete lighting to showcaee the interior of the build...with the ability to turn it off when/if I want. Not talking about any full-out RGB lightshow.

Nope, not much. Have an LED lighting a flow indicator in the water cooling loop on my main rig but that is about it.

First thing I do when I'm face with a new "thing" is find out how turn off as much of the "bling" as possible.

Mark - I wouldn't call your LED lighting up a flow meter as "bling" as it is serving a useful function.

CPU block and inside bottom of reservoir so that it illuminates the water.

Enough if I open the case that I don't need extra light.

Hi Mark,

The only RGB LEDs I have are on the motherboard. They're still running from when I first built this a few months ago. Doesn't really bother me so I leave them running. I did uninstalled the control software, ASUS Aura, so that this new motherboard wouldn't get bricked. :)

Which reminds me... It's getting time to blow out dust again. I'm waiting for the forced update for Windows 10 though.

As someone said, Mark, the lighting on the flow indicator would not be considered bling since it's serving a purpose. :)

Have a great day! :)
