Generally speaking “you” do not calibrate a measurement mic. I’m restricting the discussion to measurement mics because that’s pertinent to the OP and because mics have all sorts of frequency responses designed into them on purpose.

Measurement mics (the professionally targeted kind) can with some models be purchased from the manufacturer with a calibration file that can be used by various audio measurement software packages. There are also places that will calibrate your mics for you. In the end what this really means is just figuring out the frequency response characteristics of a given mic relative to a known source. This could just be a case of “we match it to this mic over here.” As long as all the mics someone is using are calibrated to the same standard then it’s less important that they’re perfectly flat in frequency response. I have some really good mics but the bulk of my measurement mics are inexpensive and not calibrated. They work fine though because they all measure close enough to the same that once you figure in all the external parts of a system (the room for instance) the mics minor variations become insignificant. The important thing is that I can put 8 mics around a room and pull reliable data to tune the room and make it sound musical. At the end of the day all the measurement stuff is just there to help you scientifically quantify why a room doesn’t sound right and then you can fix it. Like the last room I tuned that had 2 blown HF drivers and the polarity flipped on some LF drivers. The ears easily said there was a problem. The tools told me right away what they were. Sure I could have found them without the tools and by tweaking settings till everything was right, but the proper tools (and knowing how to use them) makes a huge difference.

Oh my. I mean, if this guy is happy with his results then more power to him. However, this write up is a textbook case of the blind leading the blind. I don’t even know where to begin. The classic smiley faced EQ, equating spectograph with transfer function, no discussion of phase or any other time domain considerations. It reminds me of when I was 17 and thought I knew everything about computers. Then I went to college and learned how little it was that I actually knew. The author’s knowledge is me when I was 17. I however own thousands of dollars of measurement mics, audio interfaces, and software, and have experience built on decades of pro audio work using those tools and honing my craft.

It’s not my desire to slam the author but it’s also important that people don’t take this correct methodology.

I think you are vastly over estimating the size of 80K USD in $100 bills. Each bundle of $10K is about 1/2” thick. You can easily carry 80K in 100’s without looking out of place.

I still play Threes regularly. It’s super accessible but still remains challenging after years of play. I even occasionally still set a new high score.

> Except it can't, a 100 acre wind farm can produce energy indefinitely while an oil well will eventually run dry.

Perhaps more true in that the wind (as far as we know) won’t run out but wind turbines do have a limited lifespan. After 20-30 years they usually need to be replaced. Some of the components are recycled but a significant portion - including the blades - are either not recyclable or not economically recyclable. Work is being done on this but there’s no guarantee it’ll produce dividends.

For this to be a valid pedagogical technique it has to be applied properly for the intended student. As described in the linked article for middle elementary aged students it seems effective. I can easily imagine my own middle elementary aged child responding well to it.

Your experience however seems to be either in secondary or collegiate classrooms and I can easily see where this approach there would often be problematic. That said if an instructor is trying to get students to engage in critical thinking about why something works then an intentional mistake could be educational. You can copy code from stack overflow all day long but it’s going to work a lot better if you can actually analyze it and understand what’s happening.

Eating disorders and dieting are not the same thing.

I wonder how Lee would respond to the allegations that many parts of forensic science are actually junk science.

The innocence project is rather pointed example of how many times forensic science has been used improperly to sentence people to death.

My bet is all it says is the lawyers will be getting rich.

Except that a person who is literally blind found it disrespectful.

People say all sorts of stupid stuff that they don’t intend to be disrespectful but which is. When it’s pointed out by someone the appropriate response is to change your behavior, not double down and make excuses.

Here’s another example: In my state (MN) it’s not uncommon for (largely) women to refer to themselves as hunting widows when their spouses go away for the weekend to hunt during the season. They say it as a joke but it’s disrespectful and diminishing to actual widows. How do I know? I’ve been widowed.

Saw a falcon launch at SLC-40 from banana creek last February. Unlike what the article said there was no fee beyond entrance to KSC. Had no problem finding a good seating spot in the bleachers for my 7 person group about 45 minutes prior to launch.

It was loud, louder than I expected, but not painfully cover your ears loud.

My experience may be atypical. A week prior to our visit there were no scheduled launches. I just did a random check as we were driving up that morning and saw it was going on.

100% glad we prioritized the launch over spending time at the other attractions. My 7yo would agree. We still hit other things but the launch was far and away the highlight. Just wish I could have seen a shuttle launch 40 years ago when I was 7.

Don’t miss the chance to see a launch if you get it.

I agree, more of a feel good/marketing piece. Bad electric coming into a system can cause damage so protection circuits are built in to prevent that damage from happening. I wonder how many UPSs kicked in and also lowered demand. What about poorly designed devices that stopped working?

Studio Six Digital makes the very useful app AudioTools. They test all iOS devices to create generic profiles for the built in mics. They’ve found them to be very consistent which is kind of remarkable for a consumer cell phone device.

Reminds me of my first time reading the Yamaha Sound Reinforcement Handbook when I was just getting into the live sound field. Read it again a year later after a lot of time in the trenches and the things that were gibberish at first now made complete sense.

To the OP, if you find something interesting but it's above your head dig in and you'll learn. Otherwise just smile and nod. I'm by no means a software engineer though I can (and do) write code to get various jobs done. Lots of stuff here is interesting to me but lots also is of no interest and/or way above my pay grade. I'm happy to be surrounded by stuff that has the potential to challenge me to grow.

I thought Escape from Lucania and by Roberts and No Shortcuts to the top by Viesturs were both good as well.

I did not care for Roberts personal memoir On the ridge between life and death.

Annapurna A Woman’s Place and Breaking Trail. The first is about the namesake first American expedition to the top which she led, the second is her memoir. Both great reads, thankfully lacking much of the big headed bravado of other mountaineering books.

Taking the phrase “Will route IP for beer” seriously.

This reminds me of my favorite IT gear conversion when someone turned a SGI challenge into a mini fridge. I have a fondness for all things SGI (Irix era) due to labs full of Indys during my college years.

I was pretty surprised to find that the project documentation was uploaded to a modern website when I searched. I figured like many things of its era that it had been lost to web rot.

Yes. It never said that the screw falling out would have been ok. The effect would have been the same where the flap ground connection would have found its way home via the feather system. Loose vs completely gone are just two points on a continuum of badness.

It’s amusing when the author says “when the phone crashes.”

My 2022 Subaru Outback head unit frequently crashes or is really unresponsive. My iPhone never crashes.

Car infotainment systems are garbage. I’d never buy a car without CarPlay. It’s maybe the #1 measure I have for vehicle quality when I rent on vacation.

I got sick of repairing and rebuilding my in-laws windows PC about 7 years ago and moved them over to the largest ipads that were available at the time. It was 100% the right move. I haven't had to fix their computer in the past 7 years. Bought refurbs to keep the price down but it was still a couple grand total for two units. I got the cell enabled ones too so they work when they travel. Totally worth it.

A couple years ago I finally got them to switch from their pre-paid flip phone to an iphone. That's also gone extremely well. They own a Thor RV which (no surprise) has a terrible OEM stereo. Replaced that with a carplay capable one with a giant (but pretty low res) screen and that's made their RV travel GPS integration far less buggy than when using plain old bluetooth.

TBH moving them to iOS from windows was far less of a painful process than I expected and I'm pretty apple positive. The fact that it just works and they really can't 'f it up makes a big difference. Now they can download all sorts of shit games and I really don't have to worry about the system getting hosed. If I considered how much I value my time and the frustration multiplier then it's an investment that has easily paid back in multiples.

My thoughts exactly. If feature X is important enough to do all the silly workarounds they did then why would you in the first place choose a provider that didn’t support feature X?

The choice of IPV4 + shenanigans vs IPV6 seems pretty straightforward.

There’s been sewage in the seas and oceans for as long as there’s been sewage in proximity to those places. Long before caring for the environment as it’s now understood was even a concept. I’d hazard a guess that on a population density normalized comparison for developed countries there has never been a better time for responsible sewage handling. That’s not to say that there aren’t plenty of problems like this article highlights, just that it probably has not been better in the past. Hopefully the UK courts will hand this lady a decisive win and reinforce the idea that industry does have responsibility.

Yeah. I was out of town hiking in Wyoming at the time and was told it was the 35E bridge by a passing hiker who relayed the news to me. My mom drove the 35E bridge twice a day. I couldn’t hike out and call home fast enough. I didn’t know anyone who was on the bridge when it fell but I do know many who missed being on it by minutes. Scary stuff.

I 100% agree on the correlation of price and reliability in the professional video world. My experience is in live event production and while Blackmagic has revolutionized the accessibility of high-quality production it does come with a non-dollar price. I've never had a Ross router, switcher, or other auxiliary gear go down during a show. I have experienced multiple show stopping failures of Blackmagic devices. I once was on a show where the BM router locked up fight before showtime. Doors were open and power cycling was not an option. All existing routes were passing signal just fine, it was just control that was gone. We just had to make do for the event, fortunately there were no critical audience facing changes that we needed.

For some clients the savings are worth the risk. For others they absolutely are not. With live you get no chance to shoot it on another day or go back and fix it in post. If there's thousands of people outside the room watching you better make sure that signal chain is rock solid.

100% right. I completely forgot about that. Thanks.

There’s a whole class of people working in manufacturing who are lining up to disagree. I recall seeing a woman on a TV show once who had been doing the same job in a sausage plant for 40+ years. She wasn’t a beaten down slave, she just found her joy and identity elsewhere.

My background is systems operation. The exception I could see to this is when there are rewards/incentives/etc for uptime or non-change-window uptime. Usually this would be coupled to meeting the goal of 4 9's or 5 9's of uptime, meeting SLA requirements, etc.

Granted, in my time working for a major 3 letter tech company on account with a major finance company my highest exposure to VP/C*O types was fixing the fallout from a whole chain of corporate culture related mistakes. If I hadn't already had a job lined up elsewhere I probably could have gotten a good bump out of it. I doubt that would have happened if I'd identified and fixed the problems. Part of that busted corporate culture. We didn't have metrics around uptime/SLAs there though which considering the clients business was pretty ridiculous.

This is critically important, as understanding the underlying cause of these conditions will allow us to develop targeted therapies for patients in the future,” said Prof. Matthew Campbell, Professor in Genetics and Head of Genetics at Trinity, and Principal Investigator at FutureNeuro.
