content: Looking to acquire some sort of high CPU performance server to do Xen things on, and while I am looking around on Ebay, a friend told me a better place to look might be more local auction houses. I live in New York, and am wondering if anyone's got any ideas as to exactly where I might find such a place.

If you have tech companies or datacenters in the area you might get lucky. You could also look around for computer recycling businesses as some of them sell usable surplus.

Boosting audio in windows (specifically, microphone headset) - Page 1

content: I just thought I'd share this tidbit with anyone who, like me, has been frustrated to no end trying to improve microphone levels in Windows 10. Ever since upgrading I've had no options for microphone boost on my headset and even after plugging in a USB Bluetooth headset (LG Nortel Bluetooth 8502) I still had no options to boost mic input! I was trying to make VOIP calls and people say they can barely hear me on the other end! I have to shout all the time!!!!Anyways, after some searching and leading to dead-ends (people saying to use Windows troubleshooter and trying to find updated drivers, etc) I stumbled on this video which solved the problem. I have no connection whatsoever to this person:It seems the *SECRET SAUCE* is installing a program called "EqualizerAPO64" found here:https://sourceforge.net/projects/equalizerapo/With that program alone you can create pre-amplifier gain on the mic to boost the audio. You need to add it to the configurator and then reboot, but once installed it seems to be persistent. You then run a configuration editor and play around with various filters in the chain. Most importantly, it works! The video suggests another program ("PEACE") but I haven't bothered with it, as the first one does all I need. I assume the second program is a more user-friendly graphical interface and lets you do more custom-tuning:https://sourceforge.net/projects/peace-equalizer-apo-extension/?source=directoryWhy Windows 10 couldn't let me do something as simple as boost my microphone (which I had done years past) is just downright upsetting. Thankfully these 3rd party programs exist, which some of you are probably laughing about having known about for years already. I'm new to this... just hope it helps others get around these Win10 frustrations with audio. Well at least it saved me from having to buy another headset only to realize it is not the microphone at all but Win10! Now all my headsets work as they should!

content: If you've been following my previous posts on bad pixel rants and weird memory issue rants, you might know that I bought a SP7 on launch, then replaced it over and over again in search of one without bad pixels and memory instabilities.Well, the 7th unit I got is starting to show memory issues.On the last unit, the device constantly BSOD when I assign an SD card with a drive letter other than default one, and it is highly repeatable.On this unit, it suffers from video stuttering, random lags and other graphic-related bugs that are not seen before on other laptops models.Just like the previous one, Windows memory diagnosis tool reports no issue with default settings, and with cache-off settings, even basic test can't be passed. To be precise, it gets stuck there forever.Question I want to ask is, is there anyone who has an SP7 or any Ice Lake based laptop and are there any weird things happening? I tried Googling, with no yield.I think I might have just written off $1400 since MSFT China does not honor global warranty, just like any other Western brands here.And since the instability issue is not reliably reproducible, I don't think even MSFT USA will honor the warranty. The previous returns were done at BestBuy before return periods.So, did I just throw away $1400? It doesn't crash, though. I never had a SIGSEGV or BSOD, just video glitches, small but noticeable ones, everyday.

There are plenty of apps that are designed to transfer SIM content from one phone to the new phone, and just look for one with reasonable ratings, no adverse comments in the reviews and it probably is ad supported, so ignore the ads, and uninstall after use.

content: The UNIX epoch bug is causing YouTube videos to state that they are scheduled to be taken down due to a copyright strike on "December 31st, 1969" (1/1/70 minus the time zone difference between UTC and PST). I made a video documenting my frustrating experience with this problem:I don't normally ask for this, but please comment on, rate, and share this video to help the algorithm pick it up and maybe get it noticed by someone who can fix the problem. I have tried contacting YouTube in all the ways available to me (even sending a Tweet to Susan Wojcicki) but so far no luck in getting it resolved.And lately my channel has suffered the same fate as Fran Blanche's in 2018: views are declining and my subscriber count is barely breaking even, despite my best efforts to consistently produce good content. Some of my subscribers say they don't get notifications of my new videos even with the bell icon clicked. So if you haven't been seeing anything from me in a long time, please give my channel a look and catch up.

Turning off the above allowed the keyboard to be detected in a USB 2.0 port. Its curious though that this doesn't seem to be an issue with the built-in USB 3.0 port until the USB 3.0 hub is plugged into it.

If not, it might be better to use different pinouts, so you can't accidentally swap the two connections.Also, wouldn't it be preferable to mount the female connectors in the PSU, so you can't short out the pins by accident? Might not be too critical though, as the PSU probably can handle a shorted output.

Ex.:They don't seem to come off - even 99.8% IPA + q-tips can only manage to scrub it off a little, and that's after some vigorous attempts.It's clearly a problem with the ultrasonic bath those receive on the manufacturing process, but why exactly? Improper temperature/cleaning solvent/less time than required?Also, most companies today use a matte varnish (conformal coating?). How do they compare to what the industry used ~20 years ago? Boards from the Socket 3/Super 7 era seemed to be more robust that what we have today.

But what your looking for is the data column. Which is what the drive is reporting. Threshold is when it starts reporting a value. Which for reallocated sectors you can see it hides its health until 140 have been used up. This is why many rules of thumb about preparing to replace a drive when you see that count changeSmart data can also help catch things like crappy data cables when you see data crc errors start to spike.

Ehh, I thought, but limited space a lab not much choice to rid off 'behemoth' and squeeze two new ones in.Eventually, to my surprise, the case has 2 PSU bays and allows extra space to accommodate another E-ATX board. Relief!Just a small workaround - aluminium tray with few holes to support MB and still need print/find spacers to level it out.

content: Yes, I heard that MS is going to launch a new version, after all this time. They pretty much shut down the lab that was developing that, and they sold licenses to third parties (in 2009 or so?). The most (and only?) known "successor" was Prepar3d:https://www.prepar3d.com/Then MS released some kind of toy replacement: "Microsoft Flight". It was definitely a toy game compared to FS.Funny they decided to get back to it. Not sure why. Maybe as a gesture to promote MS technologies? (But there's got to be a reason why they decided to stop in the first place...)Anyway, that should be interesting. FS X was pretty advanced, and you could get images pretty close to what can be seen in this video already, with the proper settings and a couple extensions like REX, and customized areas. No computer could really run it to its full potential when it got released, but a few years later, it became a very decent simulator as computers could handle the job.

I don't want to mix brands and then have problems when cable-A tries to connect to mag-dongle-B that's inserted into the usb-c port of my phone.anyone have any info on this subject?they idea is really good; I'm just wondering if/when they will be standard.

content: So I'm thinking of replacing my Obi 200 with something more intricate and capable of more interesting tasks.To do this I'd be setting up a dedicated Asterisk server, and I'd like some FXS card(s)/module(s) to go with it.Obvious things being obvious, this is something that I'd want to buy on a budget, I do not want to spend much on the hardware, but I do want to ensure there is no major trap or pitfall I might be walking into.I've looked at what seem to be TD400P clones on Amazon for acceptable prices, this example being a 3x FXS 1x FXO model.https://www.amazon.com/dp/B07SBK3FL4/I'd basically want to ensure that it won't catch fire, it will do what it needs to do, and it will work with Asterisk. If someone could also tell me if A. Asterisk can use Google Voice as a VoIP provider still (I'm finding conflicting reports), and B. Do these FXS modules support pulse dialing (as opposed to tone dialing)? Might be an odd question, the manual for a real TD400P states it might.Thanks for any advice that could be rendered, I'm not experienced in the slightest with PBX or phone routing stuff, it just seems like a neat waste of money.

Both Discord and Teamspeak have proprietary licenses, but those are pretty liberal for individuals and small teams. I just would trust Teamspeak much more. Also, last I tried Discord, the app was much more ressource-hungry.Just my opinion.

I trust it more than I trust Skype or Discord. You can read the FAQ/Help/Forum to get more info.You can try it quick. The default server is: voice.teamspeak.com.
