If anything breaks on the desktops, 99% of the time it's just a hard drive that bricked, and if you are donating blood by changing out a hard drive, you need a new profession. To remove the hard drive on a Dell Inspiron N4010, you have to first remove no less than forty screws, the keyboard/bezel, and the logic board. I got to that last step and decided to just drill through the top of the board instead.

ACEofsnett posted:I spent over a decade working for my dad, who owns a cutter grinding business. He is one of the last small shops in New England that resharpens and customizes metal cutting tools of all kinds, mostly carbide endmills for aviation and firearms work. He doesn't make standard, basic endmills anymore, as the profit margins are too small. A standard cheap carbide 1/2" four flute uncoated endmill with no radius is only about $20-30 from a big supplier. However, these companies use so many of them that they pay for resharpening of even the cheapest Chinese made tools, sometimes many, many times. What I'm saying is that they do not encourage the breaking of said tools. We don't even use regrinds anymore because we get good enough cutter life as it is and it seems like the regrinds have more problems with tool chatter than new ones

(There is, of course, little reason to do this unless you feel that life is empty without sudden loud noises). The paper mentions that "Introducing N-oxides onto the tetrazole ring may . . . push the limits of well-explored tetrazole chemistry into a new, unexplored, dimension.", but (of more immediate importance) it may also push pieces of your lab equipment into unexplored parts of the far wall.

Giving blood to the computer gods is mostly in the poor, disheveled past for me. I still have an optical drive for ripping cds to FLAC, my audio stuff is good enough that lossy formats simply won't cut it. I use a standalone blu-ray player, though, can't be hosed to install lovely software that can't keep a steady frame rate on a rig that can play Shadow of Mordor at 4k resolution  . It's when I help other people with their junk that I get hosed up now.Also, I'm pretty sure we had the dangerous chemical talk several times already, just saying.

I seem to remember my dad talking about working with florurine ( i believe) that was a gas that when you breathe just a bit of it you die of your insides chemical burning as it reacts to the water in you. My speakers and receiver have a thd of .00001 and I have special mats to minimize flooring vibrations they onky cost 10k youguys but thats a small price to pay for audio quality.

To bring some failure into this budding audiophile derail I'll have to get a picture of the leaking filter caps in my 1977 Onkyo TX-4500. It's hi-fi, vintage audiosnobbery distilled. It's also my favorite receiver and I've had it since I was 13 and was bought new by my pops right before I was born. Luckily the power transformer wasn''t damaged and I'm going to recap the whole thing this month. I had to spend about two hours going through capacitors on Digikey which caused my eyes to blur and a headache so there's a physiological failure here as well. I'm not doing it quite right and still listen to them but with higher end audio stuff you can easily hear how lossy satelite radio or mp3s can be though that might be my no name speaker wires and RCA cables.

A thorough recapping should be easy enough, it's just time-consuming. If you're using older speakers as well, it might be beneficial to recap the crossovers as well. Caps (electrolytics in particular) do wear out over time and change the characteristics of the circuit. The most noticeable effect is a more muted treble response, but it happens so gradually that you don't notice it. It's a bit like shock absorbers, actually. But when you recap the boards and the treble is restored, it's like getting a new pair of speakers again. This is also why audiophiles think that "upgrading" crossover caps to audiophile-approved versions improves the sound. They're not upgrading anything, they're just putting the crossover back to original spec. RE: MP3, music encoded with LAME at -V0 or 320kbps is virtually impossible to tell from the CD or lossless original. You need a quiet environment and ideally a good set of headphones, and you have to listen very carefully while comparing directly with the original. Even then, it'll still be transparent on a lot of music. Stuff with lots of treble content, cymbals etc. seems to be the "easiest" (still relatively hard). Most people are perfectly happy with 128kbps in blind tests. Even at 128kbps, you'd have to compare directly to the original to notice a difference. With how good modern LAME versions have gotten, to simulate the bad old days of Xing-encoded Napster MP3s, you have to go all the way down to 32kbps and force the most simplistic psychoacoustic model. It'll sound like utter poo poo, and the Xing encoder is probably single-handedly responsible for people having bad knee-jerk responses to the slightest mention of MP3, even today. More modern codecs such as AAC and Ogg Vorbis are even harder to distinguish. I have a couple of really hard to find albums that I was only able to find as 96kbps AAC rips, and I certainly don't feel like I'm missing anything. Maybe if I compared directly to the original, but then I would have the original and it would be a moot point. Yes, I'm a bit of a  when it comes to this stuff, but I'm certainly no woo-woo audiophile.There are some great threads in IYG where this sort of discussion isn't a derail: http://forums.somethingawful.com/showthread.php?threadid=2389259 http://forums.somethingawful.com/showthread.php?threadid=3021252 http://forums.somethingawful.com/showthread.php?threadid=3166333 KozmoNaut fucked around with this message at 09:09 on Feb 11, 2015 |

Lossy codecs usually have noticeable dynamic range compression, which will gently caress over your enjoyment of music once you know about it. Lossless formats are the only way to avoid these problems. This isn't $10,000 voodoo cable territory, you can pick this stuff up with ABX testing.

EightBit posted:Lossy codecs usually have noticeable dynamic range compression No, they absolutely do not. This is an extremely common misconception that keeps getting fueled by misleading articles by audiophiles or others who are woefully unaware of their own ignorance, just like the whole "digital audio is stairsteps" idiocy that is still being bandied about. Both are 100% factually wrong. Data compression and dynamic range compression are two completely different things. Dynamic range compression is applied at the mixing/mastering stage to "flatten" out the loudness profile of tracks, and is the primary reason why a lot of modern music sounds 'squashed', uniformly loud and lifeless. It has literally nothing to do with lossy compression. The most obvious thing that MP3 does is to apply a low-pass filter to cut out the highest treble frequencies. This low-pass filter sits lower and lower in the frequency range as you go down in bitrate. At 320kbps, the filter is set at 21kHz, at 128kbps it's at 17.5kHz and at 64kbps it's at 11kHz. But there is absolutely no dynamic range compression added.

I'm late for mill chat but still. I worked at my dad's company for a little while when I was just out of high school. They rebuilt stators and rotors for industrial electric motors. Pretty big ones.  Thats the housing for the stator, to give a better sense of scale. I was running an ancient milling machine there, almost exactly like this one:  I'm pretty sure it was even this brand. Anyway, the big nut that the heavy rear end table rode up and down on decided to strip out and fail on me while I was rapid traveling it up, thus dropping the table and everything on it like a rock from over waist height to the ground. The sound it made when it hit the metal base plate thing was a lot like the sound in a cartoon when they drop an anvil. That base plate saved my feet, and that was the closest to making GBS threads myself I've ever came. edit: found the picture of the assembled stator, might as well link it. bullets cure cops fucked around with this message at 22:07 on Feb 11, 2015 |

Yeah, the parts where tolerences were tight were more in the stacks of thinly cut steel, which was cut by a nice new laser, and the lathe turned shaft of course. I only did it for about a year but I kind of miss playing around with all the ancient mills and lathes. Definitely lots of potential for horrible mechanical failures though. VVV christ  VVV

I never saw it go wrong, but the job that felt most likely to end in dismemberment was definitely sanding the completed rotor on the lathe. not my picture:  Basically, looping a strip of sandpaper over one of these (some of them were a lot bigger in diameter and length than this), and running the sandpaper from one end to the other, while taking care to lean away from the lathe, and grip the paper as lightly as humanly possible so as not to get pulled into the potential meat grinder. I uh, wasn't really allowed to do this part.
