So what do you do with a designer furniture

once you own one?

@ElVerdeRican @TheATX1 The current “park” is such a joke.

@data_atx Do you see improvements like this happening in north Lamar in the next 5 years realistically? I’m personally curious about that area

@codyaims Modern Drilling Practice

@CalebChamberla6 They have a similar philosophy in some electrical design softwares. Want a 10k resistor in your schematic? Open up the yageo catalog and find a part number. Forces you to always fully define everything.. package size, material, temperature coefficient, tolerance, etc.

@Xaraphim @K_leeeb The accuracy limit of this process is just that of the reference flat. A CNC actually does a pretty poor job of making things flat.. +/-0.5 thou over a large area would be considered good. Larger the area worse it gets. Hand scraping works over arbitrarily large areas

[op07 @TheReal6Liter]

@Xaraphim @K_leeeb You can easily buy granite or cast iron reference plates that are flat to 50 micro inch over the whole area. Coat the plate in some dye and then carefully set the part down and rub in the dye. The dye transfers to the workpiece and indicates where material needs to be removed.

@Xaraphim @K_leeeb The hand scraper tool is just a convenient way to remove shallow slivers of metal in a spatially localized manner. There’s no magic in it. I have done this with an angle grinder. Just takes a gentle touch

@I_loves_deep_nn Complex, precise things are not complex, they are just precise. Ok I’m confused

[op07 @TheReal6Liter]

Ok. FWIW, industry really tried to make e beams work for production. People worked on it for years while everyone was waiting for EUV.

The issue is e beams have a trade off between write speed and resolution. Higher resolution comes at the cost of reduced beam current and thus greatly increased time to write the pattern. The process is limited by the exposure sensitivity of e beam resists, which is very poor compared to optical photoresists.

I don’t know the production rate of EUV systems, but let’s say they process 50 waters per hour with 60 dies on each. I believe a modern variable shaped beam electron beam writer would take over a day to perform the equivalent operation on a single die. That means ~60 days for the full wafer, or 0.0007 wafers per hour. So e beam is five orders of magnitude off in terms of production rate.

@dirtman It is weird how rare rectangles are in nature, yet humans love rectangles.

[op07 @TheReal6Liter]

@kalocide @I_loves_deep_nn How much time do you think it takes to e beam one die?

[op07 @TheReal6Liter]

@HououinTyouma @I_loves_deep_nn No way e beams are fast enough. Are not even the modern parallelized e beam systems still substantially slower than EUV and hardly competitive on resolution?

@dirtman Basically a bunch of supposedly elite intellectuals are slighly more scared than last year, but they’re not really sure what wrong with the world or how to fix it.

@ouranometrian2 Guys I think enough people have spoken out about how difficult gaining 20lbs of muscle is. Congratulations, that is the only reason why it’s powerful (because not many people can do it)

[op07 @TheReal6Liter]

@TheCatholicEngr Men, let’s do better. We’re not slamming the weights loud enough to scare away the thotties

[op07 @TheReal6Liter]

This captures exactly what is wrong with so many churches. The groups become dumb little therapy sessions where people repeatedly nag God for help with whatever minor life struggle they are currently dealing with. Is the God we believe in forgetful, or deaf? No, he probably just can’t believe that after all he’s given us, we’re still asking for handouts and ez successes.

I’m so with you on the last statement. Gods plan for us is definitely to take action and fix our problems.

“By the sweat of your brow” good imagery there.

@servomechanica https://t.co/DhtzHSipv9 Electrical power transmission engineering is actually really cool. Also 60hz sounds so ominous and industrial. I vibe with it

[op07 @TheReal6Liter]

@codyaims I would literally overcome significant obstacles to find a woman like this

@67Designs @SutterlinDan Wait tell us about the Ohio counterfeiting gangs. Is this actually real or did you just deal with one bad shop in OH? I’ve never heard of this lmao
