Marvel's New Thor Will Be a Woman

KozmoStevnNaut Re:I've heard elsewhere this Ultimate Universe (590 comments)

Also shown here in the only true comic about Thor (and friends and foes), the Danish "Valhalla" comic by Peter Madsen. None of this Marvel junk, please.

Notice that Thor is shown in accordance with Norse mythology, as a stout man with red hair and a bushy beard. No fair-haired prettyboys here!

Best comic ever.

Ode To Sound Blaster: Are Discrete Audio Cards Still Worth the Investment?

KozmoStevnNaut Re:USB DACs (502 comments)

The conversion from electrical to optical is literally just an LED fed by the electrical signal. On the other end, it's pretty much just a photodiode outputting an electrical signal directly. There are a few extra components, but it is a very simple conversion.

Ode To Sound Blaster: Are Discrete Audio Cards Still Worth the Investment?

KozmoStevnNaut Re:USB DACs (502 comments)

Or Firewire, but fewer and fewer PCs have them, I guess. There's also Thunderbolt if you're into Apple.

Doesn't DisplayPort also do uncompressed surround sound like HDMI?

Ode To Sound Blaster: Are Discrete Audio Cards Still Worth the Investment?

KozmoStevnNaut Re:No. (502 comments)

The concept that internal noise from the PC will ruin it is a myth, at least if you use a branded PSU that gives clean power (that is cheap too if your PC is not a gas guzzler and you don't needlessly oversize the PSU). There's enough further filtering on the sound card I think.1

Even so, with a quality PSU in my system, I still get CPU/GPU-based noise on the onboard analog outputs. It's a known issue with processors in power saving modes. If the power saving is disabled completely or the CPU is loaded 100% on all cores, the noise disappears. Look it up, it's a surprisingly common issue.

I had a Xonar D1 in my PC for a while, the noise was still there, but significantly less so. With S/PDIF to an external DAC, it's completely gone.

KozmoStevnNaut Re:USB DACs (502 comments)

That's why I didn't mention the cable, just the DAC :-)

Strictly speaking, for a proper standards-compliant S/PDIF connection, it must be a 75 ohm coaxial cable. Luckily, pretty much all RCA leads seem to be coaxial (I guess it's probably the cheapest), and the impedance is close enough that it doesn't matter. If it can carry composite video, it can carry S/PDIF. I've yet to come across an RCA lead that's shitty enough that it can't handle composite video, even the $2.50 ones at the local discount store are OK.

KozmoStevnNaut Re:My sound card is an A/V amplifier (502 comments)

This is absolutely 100% the best solution if you have an AV receiver. Let the dedicated audio hardware do the sound processing it was made for.

Ode To Sound Blaster: Are Discrete Audio Cards Still Worth the Investment?

KozmoStevnNaut Re:No. (502 comments)

You can try disabling power saving on your CPU. In my PC, the lower-power states generate a lot more noise than when it's running at full tilt.

Luckily, digital S/PDIF output to an external DAC takes care of the noise completely.

Ode To Sound Blaster: Are Discrete Audio Cards Still Worth the Investment?

KozmoStevnNaut Re:HDMI or DisplayPort only option. (502 comments)

Sample rates higher than 44.1kHz/48kHz are pointless for playback anyway. Higher sample rates allow for frequencies above 22.05kHz/24kHz, but no one can hear those anyway.

Ode To Sound Blaster: Are Discrete Audio Cards Still Worth the Investment?

KozmoStevnNaut Re:Yes (502 comments)

Onboard sound sucks.

No, onboard analog outputs suck. By using a digital connection such as USB (or S/PDIF, Firewire, Thunderbolt, HDMI, DisplayPort etc.), you're passing a digital bitstream and moving the digital to analog conversion to an external device that usually has a much better signal/noise ratio.

Even the cheapest onboard sound chipsets can pass a perfect digital bitstream along via S/PDIF, even if the analog components are shit.

KozmoStevnNaut Re:DAC (502 comments)

A good DAC can be had for less than $30 now: http://www.amazon.com/D03K-Dig...

If your motherboard has an S/PDIF (coax or TOSLINK) output, get one of those and enjoy noise-free sound.

KozmoStevnNaut Re:USB DACs (502 comments)

There's no need to spend that much. A lot of motherboards have S/PDIF outputs, and with a good coax/TOSLINK DAC (like the ~$40 FiiO D3), pristine noise-free stereo sound is both easier and cheaper than buying an expensive sound card.

Ode To Sound Blaster: Are Discrete Audio Cards Still Worth the Investment?

KozmoStevnNaut Re:No. (502 comments)

Some onboard sound is noisy through the analog outputs, although I guess it's only really noticeable in headphones. For normal PC speaker e-mail notifications and whatnot, it doesn't matter.

But luckily, most motherboards have S/PDIF outputs via coax and/or TOSLINK that allow you to connect to an external DAC (like the ~$40 FiiO D3) or a reciever with digital inputs. Some all-in-one PCs and laptops (all Macbooks IIRC) have a combined headphone output and mini-TOSLINK jack, but even if they don't, you can do digital audio over USB, Firewire or Thunderbolt for not a lot of money. HDMI or DisplayPort can also transport sound, often a DAC in the monitor allows analog stereo output based on that.

The point is to remove the noise-sensitive analog parts of the signal chain from inside the PC, using a digital connection. For stereo sound, a dedicated sound card is completely overkill, when a $40 DAC and a $5 TOSLINK or coax cable will provide an even lower noise floor in real-life situations.

For surround sound applications, dedicated sound cards may still have a place, but using a digital connection to an AV receiver and letting it handle all the processing is a much better solution and integrates better with TVs, consoles etc.

Ask Slashdot: How Often Should You Change Jobs?

KozmoStevnNaut Going on 7 years in IT (282 comments)

Strictly speaking it's not 7 years in the exact same position. I have been 7 years with the same company, in 4 different functions under 3 different managers, but always with the same great colleagues, some of whom have been with the company for over 30 years.

I see a decent-paying job as a means to an end, a steady paycheck lets me have fun with motorcycles, electronics, music, movies, food, traveling, all of the things I enjoy in life. As long as the company is willing to pay me a decent wage, provide challenging tasks and projects (and with some of our applications nearing 30 years old, we see a lot of challenges), and a great social atmosphere among colleagues, I see no reason to change jobs. I also have a decent pension, premium healthcare on top of the national healthcare system and access to very competitively-priced insurance deals and so on. It's almost as cushy as an old-school government job, except I have to do some actual work sometimes.

Samsung Release First SSD With 3D NAND

KozmoStevnNaut Re:10 yr warranty hah (85 comments)

Tell that to the hard drive I switched for an SSD. I measured a drop from 33dB to 30dB measured right beside the PC during drive read/write. And that was with the harddrive mounted on rubber dampers. Most modern computers use large variable-speed fans that make very little noise.

It's true that modern hard drives are very quiet. Right up until they start seeking.

MIT flow battery tech could benefit electric cars

KozmoStevnNaut KozmoStevnNaut writes  |  more than 3 years ago

KozmoStevnNaut writes "Researchers at MIT have developed an improved version of flow battery technology, which they claim could provide at large boost in usability for electric vehicles.

From the article: "Solid particles are suspended in a carrier liquid and pumped through the system. In this design, the battery's active components — the positive and negative electrodes, or cathodes and anodes — are composed of particles suspended in a liquid electrolyte."

The researchers claim this could enable recharging times for electric cars on par with refueling times for conventional ICE vehicles. They envision replacing a vehicle's spent battery liquid with freshly charged liquid using conventional pumping technology. The spent liquid can then be recharged and reused."
