Dyatlov's interview from the 90s, which is still available on youtube [1], seems to fit better with the account given in the hit book "Midnight in Chernobyl" (which was the basis for the series,) than the story written for TV. To me the series just seemed like a rehash of the same movie tropes we've seen time and time again in dramatizations of the accident, compared to a true adaptation of book, which included a lot of updated analysis beyond the IAEA original report.

The Canon 100mm Macro is my favorite walk around lens. I really enjoy the exercise of framing shots with the prime lens. I felt like for me having a medium zoom, 24-105mm like most beginning photographers, I'd become over reliant on changing the focal length without properly evaluating the perspective and framing of the shot.

I see dB scale units used without contextual issues in near uniformity. Unfortunately, I have to agree with the OP, that microphone capsule manufactures seem to be an edge case. I'm not sure where dBV/Pa became the standard. I can understand why given 94dBSPL@1000Hz calibration standards, and the measurement equipment of the time, but I've run into my own fair share of datasheets with lines such as 'Sensitivity -45dB' with no units or other call outs for the standard in use. Thankfully, it seems like most modern datasheets use mV/Pa which seems like a much better unit in my book.

Yeah, I agree that is pretty glaring omission. To myself at least, Altavista was a huge part of that small slice of time, where it seemed instantly, the whole world finally got online with dial-up PPP, opposed to earlier when we might have been accessing the internet through gateways at a BBS, or dialup shell access from the local library or ISP.

I'm sure things seemed quite different if you were on a college campus at the time.

This is a mistake you only make once. Lesson learned when I put a boning knife through my arm in the dish rack one day. Cost me a trip in the ambulance. Absolute insanity– correct! I don't even know how it got in there with the rest of the utensils. But I triple check the sink area every time now.

There's no wheel on a one button mouse :P Sorry I am really joking here. We have a number of Avid mixing consoles from the 2010s that have extensive mouse UI wheel controls, yet they shipped with trackball controllers. They're actually much easier to use with a standard three-button scroll-wheel mouse. Haha.

I tend to agree with you. I regularly walk, sometimes up to 40 miles per month, in the suburban hellscape that is South Hill in Puyallup, WA. This is the land of major 4 lane arterials w/ turn-lanes and hundreds of unprotected two-way and four-way intersections. There’s almost no pedestrians, I’ll rarely meet other people on my way to work, and sometimes go the whole two miles without making eye contact with a single driver.

This article didn’t touch on it, but there’s another even scarier monster lurking out there. They’ve started to replace some of our larger intersections with these “Smart” traffic lights. Most drivers have a pretty well developed feel for the pattern traffic signals follow. These are pretty much random, adjusting the traffic flow based on some metrics. They use yield left turns with single direction flow and other tricks to try and control traffic. Since the light cycle doesn’t really follow any standard pattern, they’re also pretty much random when they’ll insert the protected pedestrian crossing into the cycle. It’s a death trap. There can be people waiting at a yield left turn which will be going to red, it will click on the pedestrian walk, and the opposing traffic will still be in full green, with drivers never coming to a stop. Add to that, if volume is heavy, you can stand there for 5 minutes or more waiting for a protected pedestrian crossing.

The best 68k Mac I ever had was MAE in Solaris 9 on my SunBlade 2500. Fully patched up Solaris 9 had all the filesystem and disk i/o improvements, and none of the libc changes that happened in 10 which broke all backwards compatibility.

I was so excited last year to get to work on a passion project, which has been at the back of my mind for 15 years. To design from the ground up, a guitar speaker or musical instrument speaker [1]. Something more than just a typical loudspeaker, which is optimized for things like cost or maximum sensitivity, or linearity. I wanted a design that subjectively sounded “good”. It turned out to be one of the most difficult projects I’ve ever worked on. I ended up with two different designs in the end, a standard single voice coil version, and series dual voice coil version. To me, and quite a few people I’ve let try them in different cabinets and with different guitar amps, they sound beautiful.

Usenet over NNCP 3 years ago

I follow comp.os.vms and sci.electronics.design is always hot. I think there's probably a lot of little corners of usenet which are still pretty active. I was sad to see comp.dsp die off, but it's been equally more active by the same people on stackexchange.

I had the exact opposite reaction. I grew up on UNIX. BSD, Solaris, HP-UX, then later Linux; though always as a user. The first time I ran into VMS, I fell in love. It was just such a different experience. Granted that OpenVMS has been trapped in a bubble, and that using even the latest versions, feels like you've been teleported back to 1990. I'll be really interested to see, now that the platform is much more accessible, if they can build a community of users again.

Yeah, I really feel for people here. I've been maintaining GPOs since Windows 2003 in our small business, and I never run into any of the issues most of these posts are dealing with. I download the policy files, flip the settings around so they work for our employees, and forget what most users have to deal with... If there's not someone in the loop, dealing with the problems.

It is amazing the number of hours sunk, even in our little business, into defeaturing or really just remodeling, into a more experimentally conductive fashion, any of our prototypes which involve complex lofted multi-body assemblies. This just adds another layer into the design-data stack between the design phase and cam phase, which all needs to be maintained. I'll be quite interested to see their software evolves.

VisualStudio 2013 for mixed C# / Intel C projects with all the JetBrains plugins. We have old hardware to support. Some of our other projects use a vendor specific release of clang, which I've been able to wire into VSCode, since the vendor IDE is terrible.

I haven't watched season 4 yet, after the first season it doesn't really fall into 'must see tv' anymore, where I'd bother to tune in on a weekly basis. It must be a minority opinion, but similarly, I hated season 2, and actually thought season 3 was a fun watch. I think viewed as a totally different, and not-so-serious sci-fi action series, it was okay.

You can use the Sun Type 7 USB keyboard which has a diamond symbol super key. Under Windows it functions as the Win key. Plus it has application keys on the left had side.

The section of the book where he sends Marion off to get money from Arnold, is some of the most haunting writing I've ever come across. The book is truly amazing. I've never come across another novel to so aptly relate the feelings of addiction.

The modern Comsol GUI is truly phenomenal, especially considering where it was at with the 3.x versions. It's one of the rare cases, pretty much the only one I can think of in CAD/CAM, where the effort put into a radical GUI redesign really paid off significantly and immediately.

Twitter does in fact still reset it all the time, at least on my account. I'll notice it when I run into a bunch of those recommended tweets/follows, which don't appear in the chronological feed. edit but it has been much better recently than it was when the new UI was first released.
