Isn't the women that they appointed to the finance portfolio from one of the main companies involved?


Treasury Secretary Yellen had given speeches for the brokers involved for more than 800,000 USD. Government laws allow this type of legal bribery and many Congressmen and Senators do make large fortunes from honorariums and speeches both before and after their careers in the government. This info came out of reddit's many discussions about the crooked stock brokerages and SEC oversight that can look the other way so that retail customers are harmed in order to protect the brokers or their companies from loss. Yellen has received MILLIONS of dollars for her speeches. The SEC is under her chop after all.

Used a ramdisk for temporary working space today and it dramatically increased audacity's performance when working with a two-hour-long audio file. I think this is the first time I've manually created and used a RAM disk for userland stuff on something other than an Amiga.

Supposedly electrostatic has a bad low end but great highs- personally I like the high end rolled off a bit.


For speakers yes, so you probably need woofers.

For high end headphones they can have fantastic bass but are harder to drive.

I got the shits with one company they gave me a "free" upgrade to a higher end model after I had some issues with them but it requires some gigantic high end amp. Imagine a $3k pair of headphones that keep failing after 6 months of use.

I have a fairly high end amp but it requires $$$$$$$$ to run at its full potential.

My workaround solution was to plug in a USB voltage/current measurement dongle. It has a pass-through USB socket and I plugged the transmitter dongle into that. Mine is different from the one shown here because the USB socket is on the very end of the long plastic part instead of the side as you see in the picture. As a result, my transmitter dongle was far away from any nearby usb plugs/cables and I had good clean signal to both the mouse and keyboard.


D: yeah thanks, ran into this issue the other day.

Vega 64 is still doing fine, I don't get why people bitch about the reference model blower. Temp stayed at 85 during some torture testing. Maybe if you have a gamer case with side vents/windows, and low speed fans, more noise makes it out and doesn't blend in. I have a heavy steel case (62.4lb right now if my scale is correct) with strict front to back airflow and real fans. So far only furmark has made the blower spool up fully, but it really isn't bad when it does.

Upped my 3700X's overclock from 3800MHz to 4000MHz, and had to up the voltage one step. CPU+case fans don't seem to throttle any higher during normal workloads. I ran prime95 and furmark on their highest settings, it took about half an hour for the temp to level off at 71C. Pulled some fans and blocked an intake and it hit 80C with no crash so I'd call that stable.
can't find what the stock core voltage even is, but I see people running them way higher for lesser clockspeed.
Before I upped the voltage, it just crashed and rebooted when it hit 70C. That voltage was stable at 3800MHz, and while it couldn't normally get that warm, it didn't crash if I restricted cooling.

Back at work today, so I don't have the voltages handy right now, but I think the BIOS sets voltage at the regulator, and OS userland tools grab the die voltage. It's always lower and sags noticeably from idle to prime95 torture.


CPU and GPU temps seem fully independant of each other, and It takes prime95 at it's most extreme setting to hit 70C- where my fans go from 60% to 100%. Normal stuff keeps them idle or only slightly above. Think i'm doing good on cooling. I have overspecced high speed fans, so I set the most conservative fan curve the bios allows me. I have higher flow fans and potential to use a more aggressive curve if I want.

My 5900x just runs max voltage stock, i might try PBO2 undervolting to get more performance.

Was idly looking at GFX cards, nobody has had 6000 series for months and preorders are selling out in hours. Yeah right, with supply what is I'm not giving you money upfront when you haven't even claimed inventory since november.

I've done some tests with a portable version of Firefox 85, and from them, it would feel like I'm ready to graduate from 76.0.1.
But it's only from a superficial appearance testing point of view, there may be critical issues I would not be able to tell from not using a secondary browser like I do with the main one. (IMG:[invalid] style_emoticons/default/unsure.gif)

there's also the 'silicon lottery' aspect where there's an element of luck with how easily you can push your cpu's clockspeed. for example I have mine(terribly aged fx6300@4.5GHz) set to slightly over max voltage to keep it 'stable'.
at first I thought it was a terrible job since the clocks were slightly allover the place on heavy loads with windows, but 8 years later and no longer using windows it's still alive and even maintains the clock hrough compiling, which is all the workloads I have for it these days.

I wouldnt worry too much over getting the 'perfect' overclock, if it works for your hardware and is stable enough it'll be fiiiine probably

There should be a datasheet or something, I'd think. Even if it has barely any useful info.

I've found lots of such papers (including some marked "intel confidential") for the Intel side of things.

Anyone knows whether the Animation preset for --tune is for 2d animation (traditional/hand-drawn) only or also good for 3d animation (CGI)?

Encoding using setting 4000kbps 2-pass x265 at Medium preset resulted in an acceptable encoding time (2-2.5 hours compared to 4-6 hours for Slow preset & custom parameters). However I thought the quality can be better at Medium without dramatically increasing bitrate (therefore bloating the file size, my target is always less than 3.4GB per file). The "candies" in the screenshot have visible aliasing or jagged edges and it is only one such of many examples. Maybe setting Animation for --tune can help?

Scratch that. The Animation tune still resulted in the same artifact.

There are usually tech datasheets and white papers but most people won't read them.

For this generation, I read nothing and was able to tune the computer fairly easily.

I was surprised the mobo pushed a lot of the voltages near to max on auto settings...

I might be able to get more performance by lowering voltages but need to wait for a stable bios.

Animation is usually better for large flat surfaces.

Try using -qmin and -qmax.

Also if you haven't tried CRF encoding, do that. You can also probably fix things up by not using chroma subsampling (use -pix_fmt rgb24 or -pix_fmt yuv444p).

But isn't that typical of brands to try to push settings near the max to get the most performance so that comparison tests and reviews look good? And by not using the max settings, the board can also be credited with the ability to be "tweaked" to get even more performance in each category the settings weren't set to max as the default operating point.

Higher voltages without anything else changed don't perform better. They just heat up more.

Its all about the triangle of performance now. Pump it.

Stock performance was better than promised so I can't complain, though heat was higher.

Waiting two more weeks to see if the next bios is any good.

In ffmpeg, can commands such "no-early-skip" & "no-strict-cbr" written in another way: "early-skip=0", "strict-cbr=0"?

I don't know, but this will definitely work.
CODE
ffmpeg -i input.mkv -vcodec libx265 -x265-options 'no-early-skip=1:no-strict-cbr=1' output.mkv
Evidence suggests that early-skip=0 might also work, but I'd do the 'affirmative' method instead of the negating method when possible.

I don't do much h.265 encoding (none of my hardware can do accelerated decoding, so at high resolutions it can't keep up).

If you are confused another option would be to pipe from ffmpeg into x265 and then back into another ffmpeg instance. That's doable in windows iirc but easier in linux.

Trying to see if I can actually make some money at selling computer parts...
Some stuff I already had, something I got a deal on, and attempting to part out a CL computer.
On that note, haven't decided if I want to keep my old Sapphire Pulse RX 580 yet or not.

idk anything about that card but if it's newer than southern islands i might be interested.
